Specification

1. Field of the Invention
One aspect of the present invention relates to a yarn winding machine.
2. Description of the Related Art
There is known a technique in which, in a spinning machine equipped with a plurality of spinning units, a plurality of work carts that work on the plurality of spinning units move individually to positions of the spinning units that require work (or processing), and work on the spinning units.
For example, JP Hl-213417 A discloses a technique that enables, when some of a plurality of work carts become inoperable, shifting to a state where the number of spinning units under the charge of another work cart is increased, such that the another work cart can work on the spinning unit under the charge of the inoperable work cart. This allows an operation rate of the spinning unit to be maintained.
Some of the work carts as described above have a long member such as a cable or a hose connected between

with a machine. In order to apply the above technique to such a work cart, it is conceivable to allow the inoperable work cart to travel within a range of being under the charge of another work cart when some of a plurality of work carts become inoperable, for example, by increasing a total length of the long member connected to the work cart. However, in such a configuration, it is necessary to increase the total length of the long member connected to all the work carts, which increases the cost.
BRIEF SUMMARY OF THE INVENTION An object of one aspect of the present invention is to provide, at a low cost, a yarn winding machine capable of maintaining an operation rate in an emergency when a work cart fails, even in a configuration having a work cart connected to a long member.
A yarn winding machine according to one aspect of the present invention includes: a machine; a plurality of yarn winding units provided to the machine and arranged in one direction; a plurality of work carts provided to be able to travel in the one direction, to enable work to be performed on at least a part of the yarn winding units arranged continuously in the one

direction; and a long member having a fixed end connected to the machine and a moving end connected to the work cart, for which there are two types of a first long member having a first total length and a second long member having a total length longer than the first total length. Each fixed end of each long member is spaced apart and connected to the machine, and a plurality of the work carts include a general work cart to which the first long member is connected, and a special work cart to which the second long member is connected to allow travelling in at least a part of a travelable range of the general work cart.
In the yarn winding machine having this configuration, when the general work cart fails and a travelable range of the failed general work cart overlaps with that of the special work cart, the failed general work cart may simply be removed from the first long member and removed from the yarn winding machine. Since the special work cart can take over work for the yarn winding unit belonging to the travelable range of the removed general work cart, the operation rate can be maintained. This enable cost reduction as compared with a configuration in which all the long members connected to the work cart are lengthened.

In the yarn winding machine according to one aspect of the present invention, the number of general work carts may be equal to or greater than the number of the special work carts. In this configuration, it is possible to improve maintainability of the work cart while reducing an increase in cost due to an increase in the number of second long members.
In the yarn winding machine according to one aspect of the present invention, the long member may be at least one of a cable or a hose, or may be configured by at least one of the cable or the hose and a protective guiding member that protects and guides the cable or the hose.
In the yarn winding machine according to one aspect of the present invention, the long member may be detachably provided to the work cart. In this configuration, since the long member can be removed from the work cart, and then the work cart can be removed from the machine in an emergency when the work cart fails, it is possible to reduce deterioration in the operation rate of the yarn winding machine.
In the yarn winding machine according to one aspect of the present invention, a connector insertion port that allows the long member to be attached to and

detached from the work cart may be provided on both a front surface and a rear surface in a travelling direction of the work cart. In this configuration, the work cart and the long member can be easily connected.
In the yarn winding machine according to one aspect of the present invention, in plan view seen from above, the long member may be arranged along the one direction, and provided in a plurality of rows in a direction orthogonal to the one direction. Further, a length of the second long member may be longer than a length of the first long member and shorter than twice the length of the first long member. In this configuration, for example, by arranging, in mutually different rows, the long members adjacent to each other in the one direction, a distance for avoiding contact between the long members can be shortened. As a result, it is possible to avoid an increase in size of the yarn winding machine in the one direction.
In the yarn winding machine according to one aspect of the present invention, adjacent long members may be arranged so as not to be in the same row. In this configuration, a distance for avoiding contact between adjacent long members can be shortened. As a result, it is possible to avoid an increase in size of the yarn

winding machine in the one direction.
In the yarn winding machine according to one aspect of the present invention, there may be provided a plurality of sensors that detect that the long member is positioned at a predetermined position in the one direction, and the plurality of sensors may be arranged along the one direction and provided in a plurality of rows in a direction orthogonal to the one direction. In this configuration, the sensor can be arranged at an appropriate position where the long member can be easily detected, in accordance with arrangement of the long member.
In the yarn winding machine according to one aspect of the present invention, at least one work cart arranged next inside of the work carts arranged at both ends in the one direction may be provided as a special work cart, and a remaining work cart may be provided as a general work cart. In this configuration, when the general work cart fails, the yarn winding machine can efficiently shift to a configuration that does not deteriorate the operation rate.
In the yarn winding machine according to one aspect of the present invention, the long member may be formed with a U-shaped section that is a folded portion between

the fixed end and the moving end. Further, the long member connected to the work carts arranged at both ends in the one direction may be provided such that a folding direction of the U-shaped section faces inward of the machine in the one direction. In this configuration, an amount of the long member protruding from an arrangement region of the yarn winding unit can be reduced, which makes it possible to avoid an increase in size of the yarn winding machine.
A yarn winding machine according to one aspect of the present invention may further include a control section that controls travelling of the work cart. When the control section detects that the general work cart has been removed from the first long member, the control section may control the special work cart to travel within a travelable range of the removed general work cart. In this configuration, even in an emergency when the general work cart is removed, one or two special work carts can take over work for the yarn winding unit belonging to the travelable range of the removed general work cart. Therefore, it is possible to reduce deterioration in the operation rate of the yarn winding machine as a whole.
In the yarn winding machine according to one aspect

of the present invention, the control section may manage a plurality of the yarn winding units arranged in the machine by dividing into a plurality of groups, and may execute: normal control for controlling one work cart to be in charge of the yarn winding unit belonging to one group, in a normal state where the work cart is connected to each of all the long members provided to the machine; and emergency control for controlling the special work cart to be in charge of a group under the charge of the removed general work cart in addition to a group under the charge in the normal state, in an emergency state where the general work cart is removed from the first long member. In this configuration, even in an emergency when the general work cart is removed, one or two special work carts may be in charge of work for the yarn winding unit belonging to a range of being under the charge of the removed general work cart. Therefore, it is possible to reduce deterioration in the operation rate of the yarn winding machine as a whole.
In the yarn winding machine according to one aspect of the present invention, in the normal state, a work cart that is in charge of at least one of groups set next inside of groups set at both ends in the one direction may be provided as a special work cart, and a

remaining work cart may be provided as a general work cart. In this configuration, when the general work cart fails, the yarn winding machine can efficiently shift to a configuration that does not deteriorate the operation rate.
In the yarn winding machine according to one aspect of the present invention, the control section may automatically recognize which long member among the plurality of long members is connected to which work cart among the plurality of work carts by connecting the work cart and the long member. In this configuration, when the general work cart fails, the yarn winding machine can efficiently shift to a configuration that does not deteriorate the operation rate.
According to one aspect of the present invention, even in a case of a yarn winding machine including a work cart having a configuration connected to a long member, it is possible to provide, at a low cost, a yarn winding machine capable of maintaining an operation rate in an emergency when a work cart fails.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Hereinafter, a spinning machine (a yarn winding machine) 1 according to an embodiment of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant descriptions are omitted. In this specification, for convenience of explanation, a description will be made in which an arrangement direction (one direction) of a spinning unit (a yarn winding unit) 2 is referred to as an X-axis direction, a depth direction when the spinning machine 1 is viewed from the front is referred to as a Y-axis direction, and a height direction (a vertical direction) of the spinning machine 1 is referred to as the Z-axis direction. The X-axis direction also corresponds to a longitudinal direction of a frame (a machine) 50. The X-axis direction, the Y-axis direction, and the Z-axis direction are orthogonal to each other.
As illustrated in FIG. 1, the spinning machine 1 includes a plurality of spinning units 2, a yarn joining cart (a work cart) 3, a doffing cart (not illustrated), a first end frame 4, and a second end frame 5. The plurality of the spinning units 2 are arranged in one

direction. Each of the spinning units 2 produces a yarn Y and winds the yarn Y around a package P. The yarn joining cart 3 performs a yarn joining operation in a spinning unit 2, when the yarn Y is cut or is failed for some reason in such a spinning unit 2 . The configuration of the yarn joining cart 3 will be described in detail later. The doffing cart doffs the package P and supplies a new bobbin B to the spinning unit 2 when the package P is fully-wound in a spinning unit 2.
The first end frame 4 accommodates, for example, a collecting device that collects a fiber waste, a yarn waste, and the like generated in the spinning unit 2. The second end frame 5 accommodates an air supplying section that adjusts air pressure of compressed air (air) to be supplied to each section of the spinning machine 1 and supplies the air to each section, a drive motor that supplies power to each section of the spinning unit 2, and the like. The second end frame 5 is provided with a machine control device (a control section) 15, a display screen 16, and an input key 17. The machine control device 15 intensively manages and controls each section of the spinning machine 1.
The machine control device 15 has: an input/output interface for input and output a signal to and from

outside; a read only memory (ROM) that stores a program and information for processing; a storage medium such as a random access memory (RAM) that temporarily stores data; a central processing unit (CPU); a communication circuit; and the like. The machine control device 15 stores input data in the RAM on the basis of a signal outputted by the CPU, loads a program stored in the ROM into the RAM, and executes various processes by executing the program loaded in the RAM. The machine control device 15 controls travelling of the yarn joining cart 3. Note that the travelling control of the yarn joining cart 3 by the machine control device 15 will be described in detail later.
The display screen 16 is capable of displaying information relating to set contents and/or a status, or the like of the spinning units 2. An operator can perform a setting operation of the spinning units 2 by performing an appropriate operation with the input key 17. When the display screen 16 includes a touch panel display, the display screen 16 and the input key 17 are integrally configured.
As illustrated in FIG. 2 each spinning unit 2 includes a draft device 6, a pneumatic spinning device 7, a yarn monitoring device 8, a tension sensor 9, a

yarn accumulating device 11, a waxing device 12, and a winding device 13 in this order from upstream in a travelling direction of the yarn Y. A unit controller 10 is provided for every predetermined number of the spinning units 2, and controls operations of the spinning units 2. Note that the unit controller 10 may be provided for each spinning unit 2.
The draft device 6 drafts a sliver (a fiber bundle) S. The pneumatic spinning device 7 produces the yarn Y by twisting a fiber bundle F, which has been drafted by the draft device 6, with a whirling flow of air. More specifically (however, not illustrated) , the pneumatic spinning device 7 includes a spinning chamber, a fiber guiding section, a whirling airflow generating nozzle, and a hollow guide shaft body. The fiber guiding section guides, into the spinning chamber, the fiber bundle F supplied from the upstream draft device 6. The whirling airflow generating nozzle is arranged around a path where the fiber bundle F travels. Whirling airflow is generated in the spinning chamber by air being injected from the whirling airflow generating nozzle. This whirling airflow causes each fiber end of a plurality of fibers that form the fiber bundle F to be reversed and whirled. The hollow guide shaft body guides the yarn Y

from the spinning chamber to an outside of the pneumatic spinning device 7.
The yarn accumulating device 11 accumulates the yarn Y between the pneumatic spinning device 7 and the winding device 13. The yarn accumulating device 11 has a function of drawing out the yarn Y from the pneumatic spinning device 7. The yarn Y may be drawn out from the pneumatic spinning device 7 by a pair of delivery rollers instead of the yarn accumulating device 11.
The waxing device 12 applies wax to the yarn Y between the yarn accumulating device 11 and the winding device 13.
The winding device 13 winds the yarn Y around the bobbin B to form the package P. The winding device 13 includes a cradle arm 21, a winding drum 22 and a traverse guide 23. The cradle arm 21 rotatably supports the bobbin B. The cradle arm 21 is supported to be swingable about a supporting shaft 24. When the bobbin B (the package P) is rotated in a winding direction, the cradle arm 21 brings a surface of the bobbin B or a surface of the package P into contact with a surface of the winding drum 22 at an appropriate pressure. A drive motor (not illustrated) provided in the second end frame 5 simultaneously drives the winding drums 22 each

provided in the plurality of the spinning units 2. Accordingly, in each spinning unit 2, the bobbin B or the package P is rotated in a winding direction.
The traverse guide 23 of each spinning unit 2 is provided on a shaft shared by the plurality of the spinning units 2. By the drive motor (not illustrated) in the second end frame 5 driving the shaft to reciprocate in a rotational axis direction of the winding drum 22, the traverse guide 23 traverses the yarn Y in a predetermined width with respect to the rotating bobbin B or package P.
The yarn monitoring device 8 monitors information on the travelling yarn Y between the pneumatic spinning device 7 and the yarn accumulating device 11, and detects presence or absence of a yarn defect based on the information acquired by the monitoring. When detecting the yarn defect, the yarn monitoring device 8 transmits a yarn defect detection signal to the unit controller 10. The tension sensor 9 measures tension of the travelling yarn Y between the pneumatic spinning device 7 and the yarn accumulating device 11, and transmits a tension measurement signal to the unit controller 10. When the unit controller 10 determines that there is an abnormality on the basis of a detection result of the

yarn monitoring device 8 and/or the tension sensor 9, the unit controller 10 cuts the yarn Y by stopping the spinning operation in the spinning unit 2.
A plurality of yarn joining carts 3 are provided in the spinning machine 1. In the present embodiment, a description is given with an assumption that six pieces of the yarn joining cart 3 are provided. Each yarn joining cart 3 travels along the X-axis direction so that work can be performed on at least a part of the spinning units 2 arranged continuously in the X-axis direction. As illustrated in FIG. 1, the yarn joining cart 3 travels by a travelling wheel 35 being driven by a travelling motor 34.
Next, a configuration of a travelling portion of the yarn joining cart 3 will be described. As illustrated in FIG. 3, a frame 50 of the spinning machine 1 includes an upper frame 51, a front-side column 52, a back-side column 53, a lower frame 54, and a base 55. In the Z-axis direction, the upper frame 51 is arranged at a position above the lower frame 54, and is supported by the front-side column 52 and the back-side column 53 erected on the lower frame 54. The upper frame 51 and the lower frame 54 extend in the X-axis direction. A plurality of front-side columns 52 and back-side columns

53 are provided at predetermined intervals in the X-axis direction. The back-side column 53 is provided at a position near a back side of the spinning machine 1. The front-side column 52 is provided at a position closer to a front side (a worker passage side) of the spinning machine 1 than the back-side column 53. The base 55 is installed between the lower frame 54 and a ground G, to support the lower frame 54. A plurality of the bases 55 are provided at predetermined intervals in the X-axis direction.
The upper frame 51 is provided with the draft device 6, the pneumatic spinning device 7, the yarn monitoring device 8, the yarn accumulating device 11, the waxing device 12, and the like described above. On a lower surface of the upper frame 51, an upper rail 56 extending in the X-axis direction is provided at a position closer to the front side of the spinning machine 1 than the front-side column 52. The upper rail 56 is formed by one surface extending in the Z-axis direction, in a U-shaped member arranged with an opened portion facing downward, extending in the X-axis direction, and having a substantially U-shaped cross section.
The lower frame 54 is provided with the winding device 13 described above. On an upper surface of the

The yarn joining cart 3 is placed on the lower rail 57. The yarn joining cart 3 is provided with the travelling wheel 35 that contacts an upper surface of the lower rail 57 in a state where the yarn joining cart 3 is placed on the lower rail 57. The yarn joining cart 3 travels on the lower rail 57 by driving the travelling wheel 35 with the travelling motor 34. Further, the yarn joining cart 3 is provided with a pair of lower guide rollers 36 and 36 that respectively come into slidably contact with surfaces of the lower rail 57 on a front side and a back side of the spinning machine 1. The pair of lower guide rollers 36 and 36 are individually provided near both end parts of the yarn joining cart 3 in the X-axis direction (see FIG. 1).
An upper part of the yarn joining cart 3 is provided with a pair of upper guide rollers 37 and 37 that respectively come into slidably contact with surfaces of the upper rail 56 on the front side and the back side of the spinning machine 1. By the pair of upper guide rollers 37 and 37 sandwiching surfaces of

the upper rail 56 on the front side and the back side of the spinning machine 1, it is inhibited that the yarn joining cart 3 falls to the front side and the back side of the spinning machine 1. The pair of upper guide rollers 37 and 37 are individually provided near both end parts of the yarn joining cart 3 in the X-axis direction (see FIG. 1).
The yarn joining cart 3 moves along an extending direction of the upper rail 56 and the lower rail 57 by the pair of lower guide rollers 36 and 36 slidably contacting the lower rail 57, and the pair of upper guide rollers 37 and 37 slidably contacting the upper rail 56.
Next, a configuration of the yarn joining cart 3 will be described. As illustrated in FIG. 2, the yarn joining cart 3 includes a yarn joining device 26, a suction pipe 27 and a suction mouth 28.
When the yarn Y is brought into a divide state between the pneumatic spinning device 7 and the yarn joining device 26, the yarn joining device 26 executes a yarn joining operation for bringing the yarn Y into a continuous state. The yarn joining device 26 performs yarn joining of the yarn Y (hereinafter referred to as a first yarn Y) drawn out from the pneumatic spinning device 7, and the yarn Y (hereinafter referred to as a

second yarn Y) drawn out from the package P. The yarn joining device 26 is a splicer using compressed air, a knotter that joins the yarns Y together in a mechanical manner, or the like. In the present embodiment, the splicer will be described as an example.
The suction pipe 27 is swingably supported by a supporting shaft 31, and catches the first yarn Y from the pneumatic spinning device 7 and guides the caught first yarn Y to the yarn joining device 26. The suction pipe 27 is provided to be movable to a standby position Pll, a first yarn catching position P12 for catching the first yarn Y from the pneumatic spinning device 7, and a first yarn guiding position P13 for guiding the first yarn Y to the yarn joining device 26. The standby position Pll and the first yarn guiding position P13 may be the same position. Movement (rotation) of the suction pipe 27 is controlled by a yarn joining cart control section 40.
The suction mouth 28 is swingably supported by a supporting shaft 32, and catches the second yarn Y from the winding device 13 and guides the caught second yarn Y to the yarn joining device 26. The suction mouth 28 is provided to be movable to a standby position P21, a second yarn catching position P22 for catching the second

yarn Y from the winding device 13, and a second yarn guiding position P23 for guiding the second yarn Y to the yarn joining device 26. The standby position P21 and the second yarn guiding position P23 may be the same position. Movement (rotation) of the suction mouth 28 is controlled by the yarn joining cart control section 40.
As illustrated in FIG. 4, the yarn joining cart 3 is connected with a cable (a long member) C as a power line or a communication line, and a hose (a long member) H to which compressed air is supplied. The cable C and the hose H are long members having flexibility. The cable C and the hose H are not particularly limited, and cables and hoses having various shapes or specifications can be used. The cable C and the hose H are accommodated in a protective guiding member (a long member) 60 that accommodates the cable C and the hose H. As will be described later, the protective guiding member 60 has two types of a first protective guiding member (a first long member) 60A having a predetermined total length (a first total length) and a second protective guiding member (a second long member) 60B having a total length longer than the predetermined total length. Note that a total length of the cable C and the hose H accommodated

in the second protective guiding member 60B is longer than a total length of the cable C and the hose H accommodated in the first protective guiding member 60A.
The protective guiding member 60 is a long member having a fixed end El and a moving end E2 . The protective guiding member 60 is also a member that guides the cable C and the hose H so that the cable C and the hose H follow movement of the yarn joining cart 3. A shape and a specification of the protective guiding member 60 are not particularly limited, and parts having various shapes or specifications can be used. Hereinafter, the protective guiding member 60 in a state of accommodating the cable C and the hose H is simply referred to as a "protective guiding member 60".
The fixed end El of the protective guiding member 60 is fixed to the lower frame 54 of the frame 50, and the moving end E2 of the protective guiding member 60 is connected to the yarn joining cart 3. The protective guiding member 60 is configured to be bent exclusively in an axial direction in the Y-axis direction. The protective guiding member 60 includes: a lower-stage section 61 extending from the fixed end El along the X-axis direction; an upper-stage section 62 extending along the X-axis direction from the moving end E2, which

is a connection section with the yarn joining cart 3; and a U-shaped section 63 extending from the lower-stage section 61 so as to be folded back to the upper-stage section 62 in a U-shape. In the protective guiding member 60, when the yarn joining cart 3 moves to one side or another side in the X-axis direction of, the moving end E2 and the U-shaped section 63 accordingly move to the one side or the another side.
The protective guiding member 60 connected to the yarn joining cart 3 (3A, 3F) that is in charge of groups (a region SI and a region S6 in the present embodiment) set at both ends in the X-axis direction in the spinning machine 1 is provided such that a distal end of the U-shaped section 63 faces inward of the frame 50 in the X-axis direction.
FIG. 5A is a schematic plan view illustrating an arrangement state of a plurality of the yarn joining carts 3 when viewed from above in the vertical direction. Note that SI to S6 illustrated in FIGS. 5A, 5B, 7A, and 7B described below show individual regions when the frame 50 is divided into six in the X-axis direction. In the following description, a description will be made with an assumption that 16 pieces of the spinning unit 2 are arranged in each of regions SI to S6. As illustrated in

FIG. 5A, the protective guiding member 60 is arranged along the X-axis direction in plan view seen from above, and provided in a plurality of rows (two rows in the present embodiment) in the Y-axis direction. Further, in the present embodiment, the protective guiding members 60 adjacent to each other in the X-axis direction are arranged in different rows from each other. Moreover, a length of the second protective guiding member (the second long member) 60B is longer than a length of the first protective guiding member (the first long member) 60A and shorter than twice the length of the first protective guiding member 60A.
The lower frame 54 of the frame 50 is provided with a duct 64 that guides the protective guiding member 60. The duct 64 constitutes a placing section provided to allow the protective guiding member 60 to be placed. More specifically, the duct 64 contacts the lower-stage section 61 of the protective guiding member 60. The duct 64 guides the protective guiding member 60 such that a position of the lower-stage section 61 does not shift, while supporting the lower-stage section 61. The duct 64 is provided so as to extend from a position close to the fixed end El of the protective guiding member 60 to one side in the X-axis direction. The duct 64 of the

present embodiment is arranged along the X-axis direction in plan view seen from above, and provided in a plurality of rows (two rows in the present embodiment) in the Y-axis direction.
At both ends of each yarn joining cart 3 in the X-axis direction, inversion sensors 67 are individually provided. At a predetermined position on the upper rail 56, detected parts (sensor plates) are provided at both ends of the regions SI to S6 of each yarn joining cart 3. Examples of the inversion sensor 67 include a contact sensor, an optical sensor, and the like. The inversion sensors 67 are arranged along the X-axis direction, and provided in a plurality of rows (two rows in the present embodiment) in the Y-axis direction. A detection result of the inversion sensor 67 is acquired by the machine control device 15, and is used for movement control of the yarn joining cart 3. Specifically, when the machine control device 15 confirms the detection result of the inversion sensor 67 while the yarn joining cart 3 is moving, the machine control device 15 determines that the yarn joining cart 3 has reached an end part of the regions SI to S6, and stops or reverses the movement of the yarn joining cart 3. In addition, in a state where a sixth unit 3F is removed for maintenance, the detected

parts (the sensor plates) of a fifth unit 3E are individually arranged at an end part on a side where regions S5 and S6 are not adjacent to each other, in order to cause the fifth unit 3E connected to the second protective guiding member 60B to travel in both the regions S5 and S6. This enables the fifth unit 3E to travel in both the regions S5 and S6.
At the moving end E2 of the protective guiding member 60, a connector 65 is formed. As illustrated in FIG. 3, the yarn joining cart 3 is provided with an insertion port 38 for attachment of the connector 65. The worker can connect the protective guiding member 60 and the yarn joining cart 3 by simple work of inserting the connector 65 into the insertion port 38 of the yarn joining cart 3. The insertion port 38 of the yarn joining cart 3 of the present embodiment is provided on both a front surface 33a and a rear surface 33b (see FIG. 1), which are surfaces orthogonal to a travelling direction of a housing 33 of the yarn joining cart 3. Further, in the present embodiment, two insertion ports 38 are arranged in the Y-axis direction on each surface of the front surface 33a and the rear surface 33b.
FIG. 5B is a schematic view illustrating an arrangement state of a plurality of the yarn joining

carts 3 when the spinning machine 1 is viewed from the front. As described above, in the present embodiment, six pieces of the yarn joining cart 3 are arranged, and the six pieces of the yarn joining cart 3 includes a general yarn joining cart (a general work cart) 130 and a special yarn joining cart (a special work cart) 230. The special yarn joining cart 230 is connected to the second protective guiding member 60B having a longer total length than that of the first protective guiding member 60A connected to the general yarn joining cart 130. This allows the special yarn joining cart 230 to have a configuration being able to travel in at least a part of a travelable range R of the general yarn joining cart 130. In the present embodiment, the yarn joining cart 3 that is in charge of at least one of groups (the region S2 and the region S5 in the present embodiment) set next inside groups (the region SI and the region S6 in the present embodiment) set at both ends of the spinning machine 1 in the X-axis direction is provided as the special yarn joining cart 230, and the remaining yarn joining cart 3 is provided as the general yarn joining cart 130.
Hereinafter, the six pieces of the yarn joining cart 3 will be referred to as a first unit 3A, a second

unit 3B, a third unit 3C, a fourth unit 3D, the fifth unit 3E, and the sixth unit 3F from the second end frame 5 side in the X-axis direction. In addition, in FIGS. 5A, 5B, 7A and 7B, the unit number of the yarn joining cart 3 is indicated by a circled number. In the present embodiment, the fifth unit 3E, which is the yarn joining cart 3 that is in charge of a group (the region S5) set next inside of a group (the region S6) set on one of both ends in the X-axis direction is provided as the special yarn joining cart 230, and the first to fourth units 3A to 3D, which are the remaining yarn joining carts 3, are provided as the general yarn joining carts 130.
For each of the yarn joining carts 3 (the general yarn joining cart 130 and the special yarn joining cart 230), the travelable range R is set on the basis of a position of the fixed end El of the connected protective guiding member 60 and a total length of the protective guiding member 60. In the present embodiment, as illustrated in FIG. 5B, each of the first to fourth units 3A to 3D is set such that the individual regions SI to S4 are to be travelable ranges Rl to R4. The fifth unit 3E is set such that the regions S5 and S6 are to be a travelable range R5. The sixth unit 3F is set such that

the region S6 is to be a travelable range R6.
As illustrated in FIG. 6, the machine control device 15 includes a spinning unit management section 15A and a yarn joining cart management section 15B. In the machine control device 15, the spinning unit management section 15A and the yarn joining cart management section 15B shown below are formed by cooperation of hardware such as a CPU, a RAM, and a ROM, with software such as a program.
The spinning unit management section 15A manages the plurality of spinning units 2 arranged in the frame 50 by dividing into a plurality of groups. In the present embodiment, the spinning unit management section 15A manages 96 pieces of the spinning unit 2 by dividing into six groups, and manages which spinning unit 2 belongs to which group.
The yarn joining cart management section 15B automatically recognizes which protective guiding member 60 among a plurality of protective guiding members 60 is connected to which yarn joining cart among the plurality of yarn joining carts 3 by connecting the yarn joining cart 3 and the protective guiding member 60.
The yarn joining cart management section 15B performs control such that one yarn joining cart 3 is in

charge of the spinning unit 2 belonging to one group (to enable a yarn joining operation of the spinning unit 2), in a normal state where the yarn joining cart 3 is connected to each of all the protective guiding members 60 provided to the frame 50 (normal control) . More specifically, each of the first to sixth units 3A to 3F is set such that each of the regions SI to S6 is to be a region of being under the charge.
The yarn joining cart management section 15B controls the yarn joining cart 3 that is the special yarn joining cart to travel in the travelable range R6 of the yarn joining cart 3 that is the removed general yarn joining cart, in an emergency state where one yarn joining cart 3 that is the general yarn joining cart is removed from the protective guiding member 60 (emergency control). In the present embodiment, in an emergency state where the sixth unit 3F that is the general yarn joining cart is removed from the first protective guiding member 60A, the fifth unit 3E, which is the special yarn joining cart, is controlled to be in charge of a group (the region S6 in the present embodiment) under the charge of the sixth unit 3F, which is the removed general yarn joining cart, in addition to a group (the region S5 in the present embodiment) under the charge in the normal

state (the emergency control).
Next, a description is given to a handling method by the worker when the yarn joining cart 3 fails, and an operation of the machine control device 15 at that time.
(1) When sixth unit 3F that is general yarn joining cart fails, as illustrated in FIG. 7A, the worker disconnects the connection between the sixth unit 3F and the protective guiding member 60, and removes the sixth unit 3F from the frame 50. Specifically, the worker removes the sixth unit 3F from a removal opening formed on a back surface of the frame 50. By disconnecting the connection between the sixth unit 3F and the protective guiding member 60, the yarn joining cart management section 15B recognizes that the sixth unit 3F has been removed from the spinning machine 1 (the yarn joining cart 3 is not connected to the protective guiding member 60 that manages the region S6). Next, the yarn joining cart management section 15B expands (switches) the range of being under the charge of the fifth unit 3E from a range of the region S5 to a range in which the region S5 is added with the region S6. As described above, a length of the second protective guiding member (the second long member) 60B is longer than a length of the first protective guiding member (the first long member)

60A and shorter than twice the length of the first protective guiding member 60A. By arranging in this way, the fifth unit 3E connected to the second protective guiding member 60B can work in a region of two pieces of the yarn joining cart 3. Then, by making the length of the second protective guiding member 60B shorter than twice the length of the first protective guiding member, the fifth unit 3E attached with the fixed end El of the second protective guiding member 60B and working in the regions S5 and S6 does not interfere with the fourth unit 3D working in the region S4.
(2) When second unit 3B that is general yarn joining cart fails, the worker disconnects the connection between the second unit 3B and the protective guiding member 60, and removes the second unit 3B from the removal opening formed on the back surface of the frame 50. Then, the worker disconnects the connection of the protective guiding member 60 at each of the third unit 3C, the fourth unit 3D, the fifth unit 3E, and the sixth unit 3F, and, as illustrated in FIG. 7B, connects the third unit 3C to the protective guiding member 60 to which the second unit 3B has been connected, connects the fourth unit 3D to the protective guiding member 60 to which the third unit 3C has been connected, connects

the fifth unit 3E to the protective guiding member 60 to which the fourth unit 3D has been connected, and connects the sixth unit 3F to the protective guiding member 60 to which the fifth unit 3E has been connected.
As a result, the yarn joining cart management section 15B recognizes that the second unit 3B has been removed from the spinning machine 1, further recognizes that the yarn joining cart 3 is not connected to the protective guiding member 60 that has been connected with the yarn joining cart 3 that has been in charge of the region S6, and rewrites (updates) the information about which yarn joining cart 3 is connected to which protective guiding member 60. Next, the yarn joining cart management section 15B expands (switches) the range of being under the charge of the fifth unit 3E from a range of the region S5 to a range in which the region S5 is added with the region S6. Further, when the second protective guiding member 60B is provided in the region SI and the region S3, it is also possible to cause the first unit 3A and the third unit 3C to share and be in charge of the region S2 that is under the charge of the second unit 3B, which is a general yarn joining cart.
In addition, even when the first unit 3A, the third unit 3C, and the fourth unit 3D fail, the failed yarn

joining cart 3 is removed by a procedure similar to above, and the range of being under the charge is switched by a procedure similar to above.
(3) When fifth unit 3E that is special yarn joining cart fails, the worker disconnects the connection between the fifth unit 3E and the protective guiding member 60, and removes the fifth unit 3E from the removal opening formed on the back surface of the frame 50. Then, the worker disconnects the connection between the sixth unit 3F and the protective guiding member 60, and moves the sixth unit 3F to the left. Next, the worker connects the sixth unit 3F to the protective guiding member 60 to which the fifth unit 3E has been connected.
As a result, the yarn joining cart management section 15B recognizes that the fifth unit 3E has been removed from the spinning machine 1, further recognizes that the yarn joining cart 3 is not connected to the protective guiding member 60 that has been connected with the yarn joining cart 3 that has been in charge of the region S6, and rewrites (updates) the information about which yarn joining cart 3 is connected to which protective guiding member 60. Next, the yarn joining cart management section 15B expands (switches) the range of being under the charge of the fifth unit 3E from a

range of the region S5 to a range in which the region S5 is added with the region S6.
An operation and an effect of the spinning machine 1 of the above-described embodiment will be described. In the spinning machine 1 of the above-described embodiment, when the general yarn joining cart 130 fails and the travelable range R of the failed general yarn joining cart 130 overlaps with that of the travelable range R of the special yarn joining cart 230, the failed general yarn joining cart 130 may simply be removed from the first protective guiding member 60A and removed from the spinning machine 1. Since the special yarn joining cart 230 can take over work for the spinning unit 2 belonging to the travelable range R of the removed general yarn joining cart 130, the operation rate can be maintained.
When the general yarn joining cart 130 fails and the travelable range R of the failed general yarn joining cart 130 does not overlap with the travelable range R of the special yarn joining cart 230, it suffices to remove the failed general yarn joining cart 130 from the first protective guiding member 60A and removed from the spinning machine 1, remove the general yarn joining cart 130 having the travelable range R overlapping with that

of the special yarn joining cart 230 from the first protective guiding member 60A, and connect the general yarn joining cart 130 to the first protective guiding member 60A to which the failed general yarn joining cart 130 has been connected. Since the special yarn joining cart 230 can take over work for the spinning unit 2 belonging to the travelable range R of the general yarn joining cart 130 removed from the first protective guiding member 60A as a substitute for the failed general yarn joining cart 130, the operation rate can be maintained.
When the special yarn joining cart 230 fails, it suffices to remove the special yarn joining cart 230 from the second protective guiding member 60B and remove from the spinning machine 1, remove the general yarn joining cart 130 having the travelable range R overlapping with that of the special yarn joining cart 230 from the first protective guiding member 60A, and connect the general yarn joining cart 130 to the second protective guiding member 60B to which the special yarn joining cart 230 has been connected. In this case as well, since the new special yarn joining cart 230 can take over work for the spinning unit 2 belonging to the travelable range R of the general yarn joining cart 130

removed from the first protective guiding member 60A as a substitute for the failed special yarn joining cart 230, the operation rate can be maintained.
Such a spinning machine 1 that can shift to a configuration that does not deteriorate the operation rate is realized by forming the plurality of yarn joining carts 3 with five general yarn joining carts 130 and one special yarn joining cart 230. This enables cost reduction as compared with a configuration in which all the protective guiding members 60 connected to the yarn joining cart 3 are lengthened. That is, even in a case of the spinning machine 1 provided with the yarn joining cart 3 connected to the protective guiding member 60, it is possible to provide, at a low cost, the spinning machine 1 that does not deteriorate the operation rate in an emergency when one yarn joining cart 3 fails.
In the spinning machine 1 of the above-described embodiment, the yarn joining cart 3 is detachably provided with the protective guiding member 60. Therefore, in an emergency when one yarn joining cart 3 fails, since the protective guiding member 60 can be removed from the yarn joining cart 3, and then the yarn joining cart 3 can be removed from the frame 50, it is possible to reduce deterioration in the operation rate

of the spinning machine 1.
In the spinning machine 1 of the above-described embodiment, since the connector 65 that allows the protective guiding member 60 to be attached to and detached from the yarn joining cart 3 is provided on both the front surface 33a and the rear surface 33b in the travelling direction of the yarn joining cart 3, the yarn joining cart 3 and the protective guiding member 60 can be easily connected.
In the spinning machine 1 of the above-described embodiment, the protective guiding member 60 is arranged along the X-axis direction in plan view seen from above, and provided in two rows in the Y-axis direction, and the protective guiding members 60 adjacent to each other in the X-axis direction are arranged in different rows. This can shorten a distance for avoiding contact of the protective guiding members 60, and can avoid an increase in size of the spinning machine 1 (the frame 50) in the X-axis direction.
In the spinning machine 1 of the above-described embodiment, there are provided a plurality of inversion sensors 67 that detect that the protective guiding member 60 is positioned at a predetermined position in the X-axis direction, and the plurality of inversion sensors

67 are arranged along the X-axis direction and provided in two rows in the Y-axis direction. This allows the inversion sensor 67 to be arranged at an appropriate position where the protective guiding member 60 can be easily detected in accordance with arrangement of the protective guiding member 60.
In the spinning machine 1 of the above-described embodiment, the yarn joining cart 3 arranged inside the yarn joining carts 3 arranged at both ends in the X-axis direction is provided as the special yarn joining cart 230, and the remaining yarn joining cart 3 is provided as the general yarn joining cart 130. This allows the spinning machine 1 to efficiently shift to a configuration that does not deteriorate the operation rate, when one yarn joining cart 3 fails.
In the spinning machine 1 of the above-described embodiment, the protective guiding member 60 is formed with the U-shaped section 63 that is a folded portion between the fixed end El and the moving end E2. Further, the protective guiding member 60 connected to the yarn joining carts 3 arranged at both ends in the X-axis direction is provided such that a distal end of the U-shaped section 63 faces inward of the frame 50 in the X-axis direction. This can reduce an amount of the

protective guiding member 60 protruding from an arrangement region of the spinning unit 2, which makes it possible to avoid an increase in size of the spinning machine 1.
In the spinning machine 1 of the above-described embodiment, when the general yarn joining cart 130 is removed from the protective guiding member 60, the machine control device 15 controls the special yarn joining cart 230 to travel in the travelable range R of the removed general yarn joining cart 130. In this configuration, even in an emergency when one yarn joining cart 3 is removed, one special yarn joining cart 230 can take over work for the spinning unit 2 belonging to the travelable range R of the removed yarn joining cart 3. Therefore, it is possible to reduce deterioration in the operation rate of the spinning machine 1 as a whole.
In the spinning machine 1 of the above-described embodiment, the machine control device 15 manages the plurality of spinning units 2 arranged in the frame 50 by dividing into a plurality of groups, and executes: normal control for controlling one yarn joining cart 3 to be in charge of the spinning unit 2 belonging to one group, in a normal state where the yarn joining cart 3 is connected to each of all the protective guiding

members 60 provided to the frame 50; and emergency control for controlling the special yarn joining cart 230 to be in charge of a group under the charge of a removed general yarn joining cart 130 in addition to a group under the charge in the normal state, in an emergency state where the general yarn joining cart 130 is removed from the first protective guiding member 60A. With such a configuration, even in an emergency when one yarn joining cart 3 is removed, one special yarn joining cart 230 can be in charge of work for the spinning unit 2 belonging to the range of being under the charge of the removed yarn joining cart 3. Therefore, it is possible to reduce deterioration in the operation rate of the spinning machine 1 as a whole.
In the spinning machine 1 of the above-described embodiment, the yarn joining cart 3 that is in charge of a group that is set next inside of a group that is set at one end part in the X-axis direction is provided as the special yarn joining cart 230, and the remaining yarn joining cart 3 is provided as the general yarn joining cart 130. That is, the fifth unit 3E that is the yarn joining cart 3 in charge of the group (the region S5) set next inside of the group (the region S6) set at one end part in the X-axis direction is provided

as the special yarn joining cart 230, and the first to fourth units 3A to 3D, which are the remaining yarn joining carts 3, are provided as the general yarn joining carts 130. In this configuration, when one yarn joining cart 3 fails, the spinning machine 1 can efficiently shift to a configuration that does not deteriorate the operation rate.
In the spinning machine 1 of the above-described embodiment, the machine control device 15 automatically recognizes which protective guiding member 60 among a plurality of protective guiding members 60 is connected to which yarn joining cart 3 among a plurality of yarn joining carts 3 by connecting the yarn joining cart 3 and the protective guiding member 60. This allows the spinning machine 1 to efficiently shift to a configuration that does not deteriorate the operation rate, when one yarn joining cart 3 fails.
Although an embodiment has been described above, one aspect of the present invention is not limited to the above-described embodiment. Various changes can be made without departing from the spirit of the invention. The following alternative embodiments and the above-described embodiment can be combined appropriately.
In the spinning machine 1 of the above-described

embodiment, a description has been made with an example in which one of the plurality of yarn joining carts 3 is exclusively set as the special yarn joining cart 230. However, two among the plurality of yarn joining carts 3 may be set as the special yarn joining cart 230. In this case, it is desirable that the yarn joining carts 3 that are in charge of groups (the region S2 and the region S5) set next inside of groups (the region SI and the region S6) set at both end parts in the X-axis direction are provided as the special yarn joining carts 230, and the remaining yarn joining cart 3 is provided as the general yarn joining cart 130. That is, it is desirable that the second unit 3B and the fifth unit 3E, which are the yarn joining carts 3 that are in charge of the region S2 and the region S5 set next inside of the region SI and the region S6, are provided as the special yarn joining carts 230, and the first unit 3A, the third unit 3C, the fourth unit 3D, and the sixth unit 3F, which are the remaining yarn joining carts 3, are provided as the general yarn joining carts 130.
In the spinning machine 1 of the above-described embodiment, a description has been made with an example in which six pieces of the yarn joining cart 3 are configured including five general yarn joining carts 130

and one special yarn joining cart 230, but the number of each cart is not limited to the above-described embodiment. In the spinning machine according to the alternative embodiment, the six pieces of the yarn joining cart 3 may be configured including four general yarn joining carts 130 and two special yarn joining carts 230, or may be configured including three general yarn joining carts 130 and three special yarn joining carts 230. Note that a cost reduction effect is higher as the number of the special yarn joining carts 230 included in the plurality of yarn joining carts 3 is smaller. Therefore, the spinning machine 1 having one or two special yarn joining carts 230 has a high cost reduction effect.
For example, when two yarn joining carts 3 are paired, one may be used as the special yarn joining cart 230 and another as the general yarn joining cart 130, and the travelable range R of the one special yarn joining cart 230 may overlap with the travelable range R of the another general yarn joining cart 130. In the spinning machine 1 according to this alternative embodiment, no matter which general yarn joining cart 130 fails, the operation of the spinning machine 1 can be continued by simply removing the failed general yarn

joining cart 130. In addition, when the special yarn joining cart 230 fails, the operation of the spinning machine 1 can be continued by simple work of disconnecting the failed special yarn joining cart 230 from the protective guiding member 60, and connecting the general yarn joining cart 130 that has been paired with the disconnected special yarn joining cart 230 to the protective guiding member 60 to which the special yarn joining cart 230 has been connected.
Although the spinning machine 1 of the above-described embodiment has been described with an example in which six pieces of the yarn joining cart 3 are provided, the total number of yarn joining carts 3 is not limited.
When two among the plurality of yarn joining carts 3 are set as the special yarn joining cart 230, the spinning machine 1 can efficiently shift to a configuration that does not deteriorate the operation rate even when the two yarn joining carts 3 are removed from the spinning machine 1.
In the spinning machine 1 of the above-described embodiment, a description has been made with an example in which 96 pieces of the spinning unit 2 are arranged in the X-axis direction, but the number is not

particularly limited. Further, in the spinning machine 1 of the above-described embodiment, a description has been made with an example in which groups are set at equal intervals and the number of the spinning units 2 managed by one group is the same, but a width of the group may be different for each group, and the number of the spinning units 2 managed by one group may be different for each group.
In the spinning machine 1 of the above-described embodiment, a description has been made with an example in which the yarn joining cart 3 removed from the spinning machine 1 is automatically acquired by the yarn joining cart management section 15B, but may be acquired on the basis of information inputted by the worker or the like via an input key 17 and the like, for example.
In the spinning machine 1 of the above-described embodiment, a description has been made with an example in which the cable C and the hose H are accommodated in the protective guiding member 60. However, at least one of the cable C or the hose H may be arranged in an exposed state without being accommodated in the protective guiding member 60, or one of the cable C or the hose H may be exclusively accommodated in the protective guiding member 60. When the protective

guiding member 60 is not provided, the cable C and/or the hose H corresponds to a long member (the first long member or the second long member).
In the spinning machine 1 of the above-described embodiment, a description has been made with an example in which the failed yarn joining cart 3 is removed from the removal opening formed on the back surface of the frame 50 after the connection by the protective guiding member 60 is disconnected. However, for example, the failed yarn joining cart 3 may roll along the upper rail 56 and the lower rail 57 to move to a removal end part at a right end or a left end of the upper rail 56 and the lower rail 57, and removed from the removal end part. In this case, the normal yarn joining cart 3 between the failed yarn joining cart 3 and the removal end part is once removed from the removal end part, the failed yarn joining cart 3 is removed from the removal end part, and then the normal yarn joining cart 3 is rearranged on the upper rail 56 and the lower rail 57 again.
In the above-described embodiment, a description has been made with an example in which the present invention is applied to the spinning machine 1, but the present invention may be applied to an automatic winder. Further, in the above-described embodiment, the yarn

joining cart 3 has been described as an example of the work cart, but the yarn joining cart 3 can also be applied to a doffing cart.
Instead of the draft device 6, a combing roller may be provided, and the pneumatic spinning device 7 may twist a fiber bundle supplied from the combing roller to generate the yarn Y.
Instead of the above-described configuration, the pneumatic spinning device may include a pair of air-jet nozzles that twist the fiber bundle in directions opposite from each other.
The spinning unit 2 may be provided with an open-end spinning device (a rotor type spinning device) instead of the draft device 6 and the pneumatic spinning device 7. The open-end spinning device is a device that separates fibers of the sliver S with a combing roller or an airflow, conveys, with an airflow, the separated fibers into a rotor rotating at high speed, and converges the fibers on an inner wall of the rotor. The yarn Y is produced by drawing out the converged fibers from the open-end spinning device.
In the above-described embodiment, a description has been made with an example in which the individual regions SI to S6 and the individual travelable ranges R

coincide with each other. However, the individual regions SI to S6 and individual travelable ranges R do not need to coincide with each other, and individual travelable ranges R may be set to exceed the individual regions SI to S6. Specifically, for example, one or several spinning units 2 arranged near a boundary between the regions S2 and S3 may be set such that the yarn joining work is performed by both the yarn joining cart 3 that is the second unit 3B and the yarn joining cart 3 that is the third unit 3C.
In the above-described embodiment, a description has been made with an example in which the inversion sensor 67 is provided to the yarn joining cart 3. However, the inversion sensor 67 may be provided, for example, in a portion that supports the protective guiding member 60 in the duct 64 illustrated in FIG. 4.
In the above-described embodiment, a description has been made with an example in which the worker removes the yarn joining cart 3 from the removal opening formed on the back surface of the frame 50, but the spinning machine 1 may be configured such that the yarn joining cart 3 can be removed from a side of the frame 50.
In the above-described embodiment, the spinning machine 1 includes a splicer using compressed air, a

knotter that joins the yarn Y in a mechanical manner, and the like as the yarn joining device 26. However, by causing the spun yarn Y from the package P to be sent back to at least the pneumatic spinning device 7, and starting the draft by the draft device 6 and the spinning by the pneumatic spinning device 7, the spinning machine
1 may bring the spun yarn Y into a continuous state.
In the above-described embodiment, a description has been made with an example in which the spun yarn Y is drawn out from the pneumatic spinning device 7 by the yarn accumulating device 11. However, the spinning unit
2 may include a pair of known delivery rollers, and the
spun yarn Y may be drawn out from the pneumatic spinning
device 7 by the pair of delivery rollers. In this case,
the yarn accumulating device 11 and/or a slack tube may
be provided downstream of the pair of delivery rollers.
In the above-described embodiment, a description has been made with an example in which each device is arranged such that the spun yarn Y supplied at an upper side is wound at a lower side in a machine height direction. However, each device may be arranged such that the spun yarn Y supplied at the lower side is wound at the upper side.
In the above-described embodiment, a description

has been made with an example in which the yarn joining cart 3 has the yarn joining device 26, the suction pipe 27, and the suction mouth 28. However, for example, a configuration corresponding to the suction mouth 28 may be provided in the spinning unit 2 or the doffing cart.
