FIELD OF THE INVENTION

The present invention relates to a bobbin loading apparatus and a method for delivering/loading the bobbins in an Auto doffer ring spinning machine. More particularly, the bobbin loading apparatus and the method for loading the bobbins is adapted to deliver the bobbins with non-uniform cross sectional area in upright position onto the transport pegs of the Auto doffer ring spinning machine.

BACKGROUND OF THE INVENTION

The Auto doffer ring spinning machine includes a number of systems apart from the already known regular ring spinning systems like headstock, a plurality of spin places, end-stock, etc. The Auto doffer ring spinning machine further includes bobbin loading apparatus & longitudinal elements for loading bobbins onto the transport pegs of the Auto doffer ring spinning machine in a desired configuration.

The present invention relates to a bobbin loading apparatus for an Auto doffer ring spinning machine, in which the empty bobbins are located in upright position over the pegs which are moving in the endless peg tray extending along the machine sides. More particularly, the empty bobbins are located in upright position with larger cross-sectioned ends thereof supported over the pegs. The bobbin loading apparatus is adapted for loading the empty bobbins over the pegs in the desired configuration & unloading of full bobbins from the pegs. The longitudinal elements comprise drive components of pegs and a gripper beam. The drive components of pegs enables them to transport the empty / full bobbin to loading and unloading area in the endless peg tray and the drive components of the gripper beam enable them to transfer the empty / full bobbins between pegs and spindles.

It is known in the related art of yam spinning, when the pre-determined amount of yam has accommodated over the bobbin supported in the spindles, the full bobbin has to be manually replaced with an empty bobbin. In Auto doffer ring spinning machine, the automatic replacing of full bobbins with empty bobbins between spindles and pegs, is executed by means of gripper beam extending on both sides of the Auto doffer ring spinning machine. As a preliminary work to facilitate auto doffing, the bobbin loading apparatus performs the sequentially loading of empty bobbins in the moving pegs one after the other and thus the pegs along with the empty bobbin moves to the respective spinning positions of the entire machine and are kept ready for doffing.

During the auto doffing process, the gripper beam which is having grippers with respect to spinning positions, which grips the empty bobbins from the pegs and place it at the intermediate peg position. And then the gripper beam moves to the spinning positions and collects the full bobbins from the spindle and place it at the pegs, then the gripper beam moves to the intermediate peg position and collects the empty bobbins from intermediate pegs and place it in the spindle. Now the machine starts its next cycle of spinning process.

Meanwhile to the next doffing cycle, the preliminary work of the loading of empty bobbins in pegs, unloading of frill bobbins from pegs and the transportation of the pegs to the loading area is carried out by the drive elements of peg fray arrangement and bobbin loading apparatus in co-operation with each other.

In the known art of bobbin loading (not shown), the apparatus consists of at least one circular drum having recess(es) / groove(s) over its periphery to collect a single bobbin in each recess / groove from the storage chamber and sequentially loads each one bobbin per peg. The circular drum performs the sequential loading operation by means of a pneumatic cylinder. The linear reciprocating motion of pneumatic cylinder is converted to swiveling motion by the drum to perform bobbin loading operation which causes problems for a reliable working performance. These problems include bobbins getting jammed in the bobbin loading mechanism itself and bending of drive actuating levers and the like.

In accordance with another prior art such as for example, US 3,531,016 there is provided a bobbin orienting and loading apparatus. The bobbin orienting and loading apparatus includes a hopper containing a supply of tapered bobbins, a chute, a bobbin carrier, the bobbin carrier includes agitating fins and a rectangular bobbin receiving opening. The bobbin carrier is employed between the hopper and the chute. The rectangular bobbin receiving opening is adapted to hold the bobbin horizontally in the opening. The bobbin orienting and loading apparatus further includes an arcuate support plate for supporting the bobbin and cam means including a pair of arcuate fingers with mutual distance there-between. The chute includes a pair of abutment members. Although a cylinder reciprocates the carrier but the carrier moves along an arcuate path of travel, thereby making the release of the bobbin held in the bobbin carrier difficult. Furthermore, the agitating fins used in the above arrangement are adapted to move along an arcuate path and cause agitation only in a portion inside the hopper and accordingly the arrangement is less effective in preventing jamming of the bobbins inside the hopper.

So it is necessary to provide an improved bobbin orienting and loading apparatus that is highly reliable and efficient in operation and that is capable of avoiding jamming of bobbins in the storage chamber.

Hence this invention is more useful and takes care of the said problems, assuring a trouble free operation and improved productivity of the machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment will now be described in detail with reference to the accompanying drawings. The preferred embodiment does not limit the scope and ambit of the invention. The description provided is purely by way of example and illustration.

The bobbin loading apparatus is adapted to deliver bobbins in upright position to the transport pegs of the Auto doffer ring spinning machine. Each bobbin is has body of non¬uniform cross-sectional area defined by a first end having a smaller cross-sectional area and an opposite second end having a larger cross sectional area. The bobbins are to be loaded in an operative vertical alignment on the transport pegs of the textile machinery, such that the second end of the bobbin having larger cross sectional area is resting on the transport pegs. Referring to Figures 1-4 of the accompanying drawings, the Figure 1, 2 and 3 schematically illustrates cross-sectional views of the bobbin loading apparatus 100 in different working positions generally referred to a as bobbin catching position (I), a bobbin delivering position (II) and a bobbin loading position (III) respectively.

Referring to Figure 1 of the accompanying drawings, the bobbin loading apparatus 100 includes a storage chamber 1 that is adapted to hold a plurality of bobbins therein and dispense one bobbin at a time. More specifically, the storage chamber 1 is adapted to hold a plurality of bobbins 2 in a horizontal position, wherein the plurality of bobbins 2 are disposed substantially parallel with random end / tip positions. The storage chamber 1 includes a bottom portion having sloping guide surfaces 3a and 3b which guides the bobbins to move purposely towards an outlet opening 4. The outlet opening 4 is generally rectangular in shape and is adapted to deliver the bobbins along the horizontal axis thereof The outlet opening 4 is configured to have an opening gap of dimensions corresponding to the dimensions of the bobbins held inside the storage chamber 1. Accordingly, the outlet opening 4 is adapted to dispense a single bobbin at a time through the outlet opening 4. The storage chamber 1 further includes an agitating member 16 disposed inside the storage chamber 1. The agitating member is adapted to agitate the bobbins 2 held inside the storage chamber 1 to prevent jamming of bobbins inside the storage chamber 1.

The bobbin loading apparatus 100 further includes a bobbin carrier 6 and a pair of inclined rest plates 5a and 5b disposed beneath the outlet opening 4 of the storage chamber 1. The reciprocating bobbin carrier 6 (hereinafter referred to as bobbin carrier 6) is adapted to receive a bobbin dispensed by the outlet opening 4. More specifically, the bobbin carrier 6 is having a U channel recess 7, adapted to catch the bobbin in a horizontal configuration of the bobbin, as is delivered from the outlet opening 4 of the storage chamber 1. The bobbin carrier 6 is provided with reciprocating means adapted to configure a reciprocating motion of the bobbin carrier 6 between the bobbin catching position (I) and the bobbin loading position (III) along a slant. Furthermore, the bobbin carrier is connected to the agitating member 16 such that the slant reciprocating motion of the bobbin carrier 6 moves the agitating member 16 inside said storage chamber 1. The said bobbin carrier 6 moves downward along a slanting direction until the agitating member 16 completely reaches the outlet opening 4. The pair of rest-plates 5a and 5b is adapted to support extreme ends of a bobbin received by the bobbin carrier 6 out of the plurality of bobbins 2.

When one bobbin is held horizontally in the U channel 7 of the bobbin carrier, the two rest plates 5a, 5b provide support to the bobbin at end / tip edges of the bobbin. The two rest plates 5a, 5b and the bobbin carrier 6 are parallely positioned in line with each other and the bobbin carrier 6 that is inclined at an angle A with respect to the horizontal.

Particularly, each rest plate of the pair of rest plates 5 a, 5b is provided with a first portion thereof disposed at an angle A for example 35° to 55° with respect to the horizontal and a second portion disposed at a second angle B for example 20° to 40° with respect to the horizontal, wherein the angle A may be greater or smaller than the angle B. The pair of rest plates 5a, 5b and the bobbin carrier 6 is adapted to facilitate sliding of the bobbin received in the bobbin carrier 6 on the pair of rest-plates and relieving of the bobbin from the bobbin carrier 6.

More specifically, the bobbin received in the bobbin carrier 6 slides on the pair of rest plates as the bobbin carrier 6 moves along the rest plates. As the bobbin received in the bobbin carrier 6 passes the point of intersection between the first portion and the second portion of the pair of rest plates the bobbin received in the bobbin carrier 6 is relieved from the bobbin carrier 6 due to change in path and is guided to a funnel 14.

In the path of travel of the bobbin carrier 6 from the catching position (I) to the bobbin loading position (III) and at the bobbin delivering position (II), there is disposed a pair of stationary cam members 12a, 12b mounted in a common plane and substantially parallel to the rest plates 5a, 5b and spaced from the rest plates 5a, 5b. The stationary cams 12a, 12b are having respective inclined guide surfaces 13a, 13b with mutual distance between them diminishing thus forming a track which converges in the delivery direction of bobbin (as illustrated in Figure 4). The stationary cam members 12a, 12b and the rest plates 5a, 5b are maintained at a distance from said rest plates, the distance being equal to a dimension corresponding to the mean cross-sectional area of each bobbin. Such an arrangement of the cam members 12a, 12b and the rest plates 5a, 5b facilitates engagement between larger cross-sectioned end portion of the bobbin with either of the guide surface 13a, 13b so as to axially shift the bobbin sideways and at the same time allowing smaller cross-sectioned end of the bobbin to pass through the space between the bottom surface of the cam members 12a, 12b and top surface of the rest plates 5a, 5b, thereby relieving the bobbin from the bobbin carrier in a first orientation, in which the first end portion of the bobbin having smaller cross-sectional area is leading while being relieved in a direction parallel to the direction of traverse of the bobbins.

More specifically, when the bobbin carrier 6 moves forwardly towards the bobbin delivering position (II) the bobbin held in the U channel 7 of the bobbin carrier 6 slides over the pair of rest plates 5a, 5b. As the bobbin 2 is sliding over the pair of rest plates 5a, 5b the end of the bobbin having larger cross-sectional area portion engages with either of the guide surfaces 13a, 13b of stationary cams 12a, 12b and as the guide surfaces 13a, 13b converges in the delivery direction, the guide surfaces 13a, 13b axially shifts the bobbin towards the smaller cross-sectioned end portion thereof. The smaller cross-sectioned end portion of the bobbin passes freely beneath the similar cam members 12a/12b to guide the bobbin to the bobbin delivering position (II). The passage of bobbin from the bobbin catching position (I) to the bobbin delivering position (II) is carried out by bobbin carrier 6, its U channel 7, the pair of rest plates 5a, 5b and the pair of stationary cam members 12a, 12b which all are positioned at an angle referred as A. The angle A of the rest plates 5a, 5b between the bobbin catching position (I) and bobbin delivering position (II) is altered to angle B, causing the bobbin carrier 6 still traveling along a path at an angle A to relieve the bobbin and drop the bobbin over the pair of rest plates 5a, 5b. From the bobbin delivering position (II), the axially shifted bobbin slides over the rest plates 5a, 5b and reaches the loading position (III) as is illustrated in Figure 3. Whenever the bobbin carrier 6 along with guide bracket 8 reaches its fully extended position, then it starts retracting to its original position of bobbin catching position (I) for performing next cycle of above operations.

At the end of the path i.e. at the end of the pair of rest plates 5a, 5b, a funnel 14. The funnel 14 adapted to receive the bobbins relieved from the rest plates 5a, 5b after the first orientation of the bobbins. The funnel 14 includes an inlet, a swap mechanism including a pair of swap plates 15 a, 15b and an outlet. The inlet of the funnel 14 is adapted to receive the bobbins in the first orientation. The swap plates 15a, 15b of the swap mechanism are disposed near the inlet of the funnel 14 for orienting the bobbins to a second orientation in which the second end portion of the bobbins having larger cross-sectional area is leading and the body of each of the bobbins is in an operative vertical alignment for being loaded on the pegs of the of the Auto doffer ring spinning machine in sequence one after the other. As per Figure 4 of the accompanying drawings, the swap plates 15a, 15b engages with the axially shifted bobbin at a smaller cross-sectioned end portion thereof and changes the orientation of the bobbin to upright position. More specifically, the smaller cross-sectioned end of the bobbin strikes either one of the swap plates 15a, 15b and the swap plates 15a, 15b urges the larger cross-sectioned end portion of the bobbin to lead while passing through the funnel 14 and thus the bobbin is loaded over pegs in the upright position with the larger cross-sectioned end portion of the bobbins resting over the pegs.

The bobbin loading apparatus 100 further includes reciprocating means that are adapted to configure reciprocating motion of the bobbin carrier 6 between the bobbin catching position (I) and the bobbin loading position (III). The reciprocating means includes a guide bracket 8, a guide rod 10, and a pneumatic piston cylinder arrangement 9. The bobbin carrier 6 is connected at a lower portion thereof with an extreme end of the guide bracket 8. The other extreme end of the guide bracket 8 is adapted to slide along a guide rod 10, when a piston of a pneumatic cylinder arrangement 9 pushes the guide bracket 8 along a direction parallel to the guide rod 10. More specifically, the bobbin carrier 6 along with the guide bracket 8 is linearly moved by the pneumatic cylinder arrangement 9, between the bobbin catching position (I) (As shown in Figure 1) and the bobbin delivering position (II) (As illustrated in Figure 2). The linearly reciprocating motion of the above assembly is aided by a linear bearing 11 provided at the guide bracket 8, in which the above assembly slides. The guide rod 10 is disposed at an angle A with respect to the horizontal and runs parallel with respect to the reciprocating movement of the bobbin carrier 6. As the piston of the pneumatic cylinder retracts and extends inside the piston of the pneumatic piston arrangement 9, the piston pushes the guide bracket 8 so as to cause reciprocating movement of the bobbin carrier 6 connected to the extreme end of guide bracket 8 between the bobbin catching position (I) and the bobbin loading position (III). More specifically, at the bobbin catching position (I) as illustrated in Figure 1, the piston of the pneumatic cylinder arrangement 9 will be at fully retracted position, at the bobbin delivering position (II) as illustrated in Figure 2, the piston of the pneumatic cylinder arrangement 9 will be at 3/4th extended position and at the bobbin loading position (III) as illustrated in Figure 3, the piston of the pneumatic cylinder arrangement 9 will be at fully extended position.

Apart from the above mentioned elements, the bobbin loading apparatus 100 also includes jamming prevention means that are adapted to avoid bridge formation or jamming of bobbins 2 inside the storage chamber 1. The jamming prevention means include an agitating member 16 as illustrated in Figures 1-4. The agitating member 16 is connected with the bobbin carrier 6. The agitating member 16 is disposed inside the storage chamber 1 and engages with the bobbins 2 disposed inside the storage chamber 1 every time the bobbin carrier 6 reciprocates. In order to facilitate entry of the agitating member 16 inside the storage chamber 1 the sloping guide surface 3b of the storage chamber is provided with longitudinally extended slot(s) 17 illustrated in Figure 4. The agitating member 16 enters inside the storage chamber 1 through the slots 17 and travels along the slots 17 to engage with the horizontally disposed bobbins 2 every time the bobbin carrier 6 reciprocates to & fro in the path of travel of the bobbin carrier 6. The regular engagement of agitating member 16 with the bobbins 2 facilitates placement of the bobbins 2 substantially parallel in horizontal manner, without any bridge formation.

At least one or multiple number of said apparatus can be employed in a machine, based upon the need. Various modifications and alternative embodiments will be apparent to those skilled in the art.

Further, the present invention also discloses a method of loading bobbins, held in a storage chamber of a bobbin loading apparatus, onto textile machinery without jamming of the bobbins inside the storage chamber. The method of loading bobbins includes the steps of using reciprocating motion of a bobbin carrier transporting bobbins from the storage chamber to the textile machinery, to agitate the bobbins stored in the storage chamber with the help of an element extending from the bobbin carrier into the storage chamber.
