BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a textile machine equipped with a winding section, and a display control device.

2. Description of the Related Art
Textile machines including a plurality of winding units are known in the art. One such textile machine is disclosed in Japanese Patent Application Laid-open No. 2012-218915. A winding unit rotates a bobbin and forms a package by winding a yarn on the rotating bobbin. For this purpose, the winding unit includes a winding section that winds the yarn to form the package. However, because the yarn is wound by rotating the bobbin, vibration is generated in the winding unit due to the eccentricity and the like of the bobbin. Therefore, in the conventional textile machines, specifically, for example, in the textile machine disclosed in Japanese Patent Application Laid-open No. H8-301523 or in Utility Model Application Publication No. H4-118462, a vibration sensor is installed in each winding unit to enable recognition of the magnitude of the vibration. However, in the conventional textile machine, it is difficult to precisely recognize which winding unit among a plurality of the winding units arranged side by side has large vibrations. Therefore, there is a need for a technology to easily recognize the winding unit having large vibrations from among the winding units arranged side by side. There is also a need for an associated technology in which the user can set a reference for determining whether the vibrations are large.

DETAILED DESCRIPTION

A textile machine according to an embodiment of the present invention is explained first in a simple manner. The technical idea of the present invention is not limited to an automatic winder 100 explained below and can also be applied to other textile machines (for example, an air-jet spinning frame or an open-end spinning frame). FIG. 1 is a drawing of an overall structure of the automatic winder 100. The automatic winder 100 mainly includes winding units 1, a transport device 2, a doffing device 3, and a control device 4 (machine control section). The control device 4 is shared by all the winding units 1 of the machine and is arranged at one end of the machine. The winding unit 1 unwinds a yarn Y from a bobbin Bl and winds the unwound yarn Y around a bobbin B2 to form a package P. While forming the package P, the winding unit 1 removes any defective portion from the yarn Y to improve the quality of the yarn Y. By doing so, the winding unit 1 can form a package P with a stable quality. Each winding unit 1 includes a unit control section 14 (see FIG. 2) .

The unit control section 14 is electrically connected to the transport device 2 and the doffing device 3 via the control device 4. Thus, the unit control section 14 allows transmission and reception of electric signals among the control device 4, the transport device 2, and the doffing device 3. The transport device 2 transports the bobbin Bl with the yarn Y wound around it up to each of the winding units 1. By doing so, the transport device 2 delivers the yarn Y to each winding unit 1. The transport device 2 also transports the empty bobbin Bl to a prescribed location after the yarn has been unwound from the bobbin Bl. The transport device 2 includes a not shown transport control section. The transport control section is electrically connected to each of the winding units 1 and the doffing device 3 via the control device 4. Thus, the transport control section allows transmission and reception of electric signals among the control device 4, the winding units 1, and the doffing device 3. The doffing device 3 has a function to remove the bobbin B2 from the winding unit 1 and collect the packages P of each of the bobbins B2.

Thus, the doffing device 3 allows collection of the fully wound packages P from the winding units 1. The doffing device 3 also has a function to set an unused bobbin B2 in the winding unit 1. The doffing device 3 includes a not shown doffing control section. The doffing control section is electrically connected to each of the winding units 1 and the transport device 2 via the control device 4. Thus, the doffing control section allows transmission and reception of electrical signals among the control device 4, the winding units 1, and the transport device 2. The control device 4 recognizes the operating state of each of the winding units 1, the transport device 2, and the doffing device 3. Moreover, the control device 4 can issue driving action instruction to each of the winding units 1, the transport device 2, and the doffing device 3. In this manner, the control device 4 performs coordination between the control targets, namely, the winding units 1, the transport device 2, and the doffing device 3. The control device 4 collects information pertaining to the operating state from the unit control section 14 of each of the winding units 1.

The collection of information by the control device 4 is performed, for example, periodically. The information collected by the control device 4 includes vibration information detected by a detecting section 141 explained later. The control device 4 includes the function of a display control section 4c (see FIG. 2) . The display control section 4c controls display of contents on a display section 5. The display section 5 of the automatic winder 100 is a touch panel, and therefore, information can also be input from the display section 5. The winding unit 1 is explained in detail below. FIG. 2 is a drawing of a structure of the winding unit 1 and a control system thereof. The winding unit 1 mainly includes a yarn supplying section 11, a processing section 12, and a winding section 13. The winding unit 1 also includes the unit control section 14. The yarn supplying section 11 has a configuration that allows the bobbin Bl to be set. During the winding operation, the yarn Y is unwound from the bobbin Bl set in the yarn supplying section 11.

The yarn supplying section 11 includes an unwinding assisting device 111. The unwinding assisting device 111 regulates the yarn Y that is unwound from bobbin Bl such that the yarn Y does not spread due to centrifugal force. The processing section 12 removes any defective portion of the yarn Y. The processing section 12 includes a tension applying device 121, a defect detecting device 122, a yarn cutting device 123, and a yarn joining device 124. The tension applying device 121 applies a predetermined tension on the yarn Y unwound from the bobbin Bl. The defect detecting device 122 detects the defective portion of the yarn Y based on a light quantity shielded by the yarn Y. The yarn cutting device 123 cuts the yarn Y when the defect detecting device 122 detects a defective portion is in the yarn Y. A yarn cut signal output at yarn cutting is input into the unit control section 14, and thereby, the unit control section 14 recognizes that the yarn cutting device 123 has been operated. The yarn joining device 124 joins the broken yarn Y when a yarn breakage occurs or when the yarn Y is cut by the yarn cutting device 123. The term "defective portion" refers to a portion of the yarn Y that is too thin or too thick or where a foreign substance is mixed with the yarn Y.

The winding section 13 winds the yarn Y to form the package P. The winding section 13 includes a bobbin supporting device 131 and a bobbin rotating device 132. The bobbin supporting device 131 rotatably supports the bobbin B2 or the package P formed on the bobbin B2. The bobbin rotating device 132 rotates the bobbin B2 or the package P formed on the bobbin B2. The bobbin supporting device 131 is explained in detail below. The bobbin supporting device 131 mainly includes a cradle 131a. The cradle 131a rotatably supports the bobbin B2 or the package P formed on the bobbin B2 in an insert-held state. The cradle 131a is swingable about a rotating axis. This feature enables the cradle 131a to make contact with a later-explained traverse drum 132b at a constant load even when the outer diameter of the package P increases with the winding of the yarn Y. Moreover, a yarn layer thickness (thickness of the portion where the yarn is wound) of the package P can be recognized by detecting a swing angle of the cradle 131a.

The bobbin rotating device 132 is explained in detail below. The bobbin rotating device 132 mainly includes an electric motor 132a and the traverse drum 132b. The electric motor 132a is driven based on instructions issued from a motor control section 132c. The traverse drum 132b is rotated by the torque of the electric motor 132a. Because the bobbin B2 (or the package P) is in contact with the traverse drum 132b, the bobbin B2 (or the package P) rotates as the traverse drum 132b is rotated. The yarn Y is guided along helical grooves provided on an outer peripheral surface of the traverse drum 132b. Thus, the traverse drum 132b traverses the yarn Y. By traversing the yarn Y, the traverse drum 132b ensures that the yarn Y is evenly wound across the package P. The unit control section 14 recognizes the operating states of the yarn supplying section 11, the processing section 12, and the winding section 13. The unit control section 14 also issues driving action instructions to the yarn supplying section 11, the processing section 12, and the winding section 13. The unit control section 14 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory).

The CPU is an arithmetic processing device that executes control programs. The ROM is a storage medium that stores therein the control programs. The RAM is a storage medium that temporarily stores therein data when the control programs are executed. All the winding units 1 constituting the automatic winder 100 have the detecting section 141 in the unit control section 14. The detecting section 141 is a vibration sensor that detects vibrations that occur during the formation of the package P. That is, the detecting section 141 is a vibration sensor that detects a vibration amount generated during the formation of the package P. The detecting section 141 is mounted on an electronic circuit board 142. The CPU, the ROM, and the RAM are also mounted on the electronic circuit board 142. The unit control section 14 always stores updated vibration detection values detected by the detecting section 141 in a storage section. The vibration detection values stored in the storage section of the unit control section 14 are transmitted to the control device 4 upon requests from the control device 4. The timing of request for the vibration detection values made by the control device 4 to the unit control section 14 can be periodic or non-periodic. The unit control section 14 can voluntarily transmit the vibration detection values to the control device 4 without any request from the control device 4. The control device 4 stores the vibration detection values received from the unit control section 14 in the storage section.

Because the detecting section 141 is mounted on the electronic circuit board 142 incorporated in the winding unit 1, no long wiring is required for connecting the electronic circuit board 142 of the unit control section 14 and the detecting section 141, and thereby simplification of the structure of the winding 15 unit 1 can be realized. In an alternative configuration, the detecting section 141 can be mounted on the cradle 131a. With this arrangement, only the vibrations generated during the formation of the package P by the winding unit 1 are detected and not the vibrations of the yarn cutting device 123 or the yarn joining device 124 and the like. The contents displayed on the display section 5 are explained in detail below. FIG. 3 is an image of a graph G in which the vibration value of each of the winding units 1 is visually arranged side by side. FIG. 4 is an image of a setting section 53 capable of setting an abnormality determination level L. A graph view frame 51 is provided in this graphic. The graph view frame 51 shows the graph G (bar chart) in which the vibration value of each of the winding units 1 is visually arranged side by side. The graph G shows the maximum value of the magnitude of the vibration value (height of the bar) of each winding unit 1 in the process of formation of one package P. The abnormality determination level L that serves as a reference for determining whether the vibration is large is displayed in the graph view frame 51.

The abnormality determination level L is a straight line extending in the direction in which the bars are lined up. The display of the components of the graph G is controlled by the display control section 4c The display control section 4c thus exerts control so as to display the graph G in which the vibration value of each of the winding units 1 is visually arranged side by side. The display control section 4c also exerts control so as to display on the graph G the abnormality determination level L that serves as a reference for determining whether the vibration is large. If the bar that functions as a visual representation of the vibration value crosses the abnormality determination level L, it indicates that the vibration is large. With the aid of such a graph, an operator can easily recognize the winding unit 1 that has a large vibration from among the winding units 1 arranged side by side. As shown in FIG. 3, etc., a display style (display color) of the winding unit 1 with the bar thereof crossing the abnormality determination level L differs from that of the other winding units 1. That is, those bars from among the bars forming the graph G whose upper ends cross the abnormality determination level L have a display style that is different from that of the other bars.

This allows the operator to easily recognize the winding units 1 crossing the abnormality determination level L. Additionally, a warning lamp can be lit, or a warning buzzer can be rung, of those winding units 1 whose vibration detection values cross the abnormality determination level L. In this arrangement, the operator can more easily recognize those winding units 1 whose vibrations are large from among the winding units 1 arranged side by side. An icon 52 is provided in this image. On tapping the icon 52, a screen for setting the abnormality determination level L is displayed. This screen can be called the setting section 53. In an alternative configuration, the setting section 53 can be a keyboard, etc., that allows information to be input into the control device 4. Once setting of the abnormality determination level L is completed, the newly set abnormality determination level L is displayed in the graph view frame 51. The display control section 4c thus exerts control so as to display the abnormality determination level L set by using the setting section 53. The operator can therefore set a desired reference for determining whether the vibrations are large.

FIG. 5 shows how the abnormality determination level L is shifted following the operation of the setting section 53. An area R shown in FIG. 5 shows the shifted abnormality determination level L. As explained above, the setting section 53 for setting the abnormality determination level L is displayed on the display section 5. The abnormality determination level L displayed in the graph view frame 51 moves up or down (see an arrow M) when the setting section 53 is operated. That is, the abnormality determination level L displayed in the graph view frame 51 shifts following the operation of the setting section 53. The display control section 4c thus exerts control so as to shift the abnormality determination level L following the operation of the setting section 53 with the graph G displayed on the display section 5. In this manner, the reference for determining whether the actual vibrations are large can be set while referring to the actual magnitude (variation) of the vibration values. For example, as shown in FIG. 5, the abnormality determination level L can be shifted upward by referring to the magnitude of the actual vibration values.

The technology pertaining to variations in the winding conditions is explained below. FIGS. 6A and 6B show the function that the abnormality determination levels L for different winding conditions are displayed. FIG. 6A is an image of display of an abnormality determination level L for a first winding condition. FIG. 6B is an image of display of an abnormality determination level L for a second winding condition. The control device 4 of the automatic winder 100 includes a storage section 41 (see FIG. 2). The storage section 41 is a storage medium that stores therein the winding conditions, such as a thickness (count) of the yarn Y and a winding speed, etc. The storage section 41 stores therein an abnormality determination level L for each winding condition. The control device 4 functions as the display control section 4c to exert control so that the abnormality determination level L corresponding to the winding condition is displayed. The display control section 4c thus exerts control such that the abnormality determination level L corresponding to the selected winding condition is read from the storage section 41 and displayed. Consequently, even if the winding conditions vary, a suitable abnormality determination level L can be set.

The technology pertaining to how the abnormality determination level L can be changed is explained below. FIGS. 7A and 7B show, when the abnormality determination level L for the first winding condition is changed, how the abnormality determination level L for the second winding condition is changed. FIG. 7A shows how the abnormality determination level L is changed for the first winding condition. FIG. 7B shows how the abnormality determination level L is automatically changed for the second winding condition. However, the graphic displayed on the display section 5 only shows changing of the abnormality determination level L for the first winding condition (the winding condition of the current winding operation) (see FIG. 7A) . Therefore, FIG. 7B is a schematic diagram for explaining the above operation. The control device 4 of the automatic winder 100 includes an arithmetic section 42 (see FIG. 2) . The arithmetic section 42 is an arithmetic processing device that executes the control programs. When the abnormality determination level L for the first winding ! condition is changed (see the arrow M) , the control device 4 rewrites the information in the storage section 41 based on a calculation result obtained by the arithmetic section 42. That is, the control device 4 exerts control such that the abnormality i determination level L for the second winding condition is automatically changed based on an amount of change made in the abnormality determination level L for the first winding condition (see an arrow m).

When instructed of a change from the first winding condition to the second winding condition, the control device 4 exerts control so as to read from the storage section 41 and display the abnormality determination level L for the second winding condition. The abnormality determination level L for the second winding condition > that is read from the storage section 41 is the abnormality determination level L that has been changed automatically. The display control section 4c thus exerts control so that when the abnormality determination level L for the first winding condition is changed, the abnormality determination level L for the second winding condition stored in the storage section 41 is automatically changed based on the amount of change in the abnormality determination level L for the first winding condition. Consequently, time and effort for manually changing the abnormality determination level L for each winding condition can be saved. The arithmetic section 42 calculates a change rate of the abnormality determination level L with its value before the change as a reference. "Change rate" is an amount of change represented in percentage from the abnormality determination level L with its value before the change as a reference. The control device 4 automatically changes the abnormality determination level L for the second winding condition based on the calculated change rate.

The display control section 4c thus exerts control such that when the abnormality determination level L for the first winding condition is changed by a certain change rate, the abnormality determination level L for the second winding condition previously stored in the storage section 41 is automatically changed for the same change rate as that of the abnormality determination level L for the first winding condition. For example, if the abnormality determination level L for the first winding condition is increased by 5%, the abnormality determination level L for the second winding condition is also increased by 5%. Consequently, the abnormality determination level L can be optimized for each winding condition. The technology whereby the winding unit 1 having large vibrations is recognized with high accuracy is explained below. FIG. 8 shows graphs G (including the abnormality determination level L), one for a period until the yarn layer thickness of the package P reaches a predetermined value and the other for the period thereafter. The outer diameter of the package P gradually increases with the winding of the yarn Y. That is, the outer diameter of the package P gradually increases as the winding of the yarn Y around the bobbin B2 (package P) progresses. During such fattening of the package P, the vibration caused by the eccentricity of the bobbin B2 keeps on increasing until the yarn layer thickness of the package P reaches a predetermined value, and the vibration goes on reducing thereafter.

That is, the vibration caused by the eccentricity of the bobbin B2 keeps on increasing until the yarn layer thickness of the package P reaches a predetermined value. One of the reasons for this is that after the yarn layer thickness of the package P has reached the predetermined value, the vibrations are absorbed by the yarn layers. Another reason is that the rotation speed of the package P reduces with fattening of the package P. Accordingly, it becomes necessary to assess the magnitude of the vibrations while making a distinction between the period until the yarn layer thickness of the package P reaches the predetermined value and the period thereafter. Therefore, the display control section 4c exerts control so as to display different graphs G (including the abnormality determination level L) , one for the period until the yarn layer thickness of the package P reaches the predetermined value and the other for the period thereafter. The display control section 4c thus exerts control so as to display different graphs G, one for the period until the yarn layer thickness of the package P reaches the predetermined value and the other for the period thereafter. Consequently, the winding unit having large vibrations can be recognized with high accuracy.

Furthermore, in the present embodiment, two graph view frames 51 each containing a different graph G are simultaneously displayed on one screen. However, in an alternative configuration, a single graph view frame 51 can be displayed on one screen, and the graphs G can be displayed one at a time by selective switching of the graphic displayed in the graph view frame 51. The term "the period thereafter" need not be limited to one period but can be a plurality of periods. The graph G representing "the period thereafter" can display the average of chronologically changing vibration values. FIG. 9 shows a graph G (including the abnormality determination level L) for each vibration detection direction. Although it is also possible to assess (determination of presence/absence of abnormality) the vibration values in one direction regarding the vibrations caused by the eccentricity of the bobbin B2, by using the vibration values in a plurality of directions, assessment (determination of presence/absence of abnormality) can be made with even greater accuracy. For example, vibrations in the two directions perpendicular to the gravitational direction are detected and the magnitude of the vibrations is comprehensively assessed.

In this case, the display control section 4c exerts control so as to display the graphs G for the two directions.The display control section 4c thus exerts control so as to display the graphs G for each vibration detection direction. Consequently, the winding unit 1 having large vibrations can be recognized with even greater accuracy. Furthermore, in the present embodiment, two graph view frames 51, each containing a different graph G, are simultaneously displayed on one screen. However, in an alternative configuration, a single graph view frame 51 can be displayed on one screen, and the graphs G can be displayed one at a time by selective switching of the images displayed in the graph view frame 51. The vibration detection directions are not limited to those mentioned above. For example, including the gravitational direction, vibrations in three directions can be detected. In the automatic winder 100, the unit control section 14 bars updating of the vibration detection values by the detecting section 141 for a predetermined period immediately after the yarn cutting device 123 has been operated. Therefore, the vibration detection values in that period are not transmitted to the control device 4. Consequently, the vibrations in that period are not reflected in the graph G. The display control section 4c thus does not reflect the vibration caused by the operation of the yarn cutting device 123 in the graph G. Consequently, the winding unit 1 with the large vibrations can be recognized with even greater accuracy.

FIG. 10 shows different graphs G, one for the period until the yarn layer thickness of the package P reaches a predetermined value and the other for the period thereafter along with a graph G for each vibration detection direction. This kind of display enables the winding unit 1 having large vibrations to be recognized at one glance. The possible patterns of the contents displayed on the display section 5 are explained next. In the graphs G shown in FIGS. 3 to 10, the vibration value is shown per package P. The vibration value shown in the graph G is not that of the package P being currently formed but of the last fully wound package P (that is, the vibration value at the time of forming the last package P). The display control section 4c thus exerts control so as to display the graph G obtained while the last package P is being formed. Consequently, it can be determined whether the vibration at the time of forming the last package P was large. In an alternative configuration, the display control section 4c can be caused to display, instead of the graph G of only the last package P, the graphs G for plural previous packages P differentiating them package-wise. This enables comparison of the vibration values of the previous plural packages P. The display control section 4c thus exerts control so as to display the graph G per package P.

Consequently, the contents displayed on the display section 5 can be simplified. If no vibration value data of the previous package P is available, for example, as in the case of formation of the very first package P, the graph G for the package P being currently wound can be displayed. Consequently, the winding unit 1 with missing vibration value can be prevented from being displayed on the graph G. The automatic winder 100 according to an embodiment of the present invention is explained above. The object of the present invention is to provide a technology for easily recognizing the winding unit 1 having large vibrations from among the plurality of winding units 1 arranged side by side and a technology associated with the above technology. The present invention can also be said to be that of a display control device because of its focus on the control device 4 of the automatic winder 100. That is, the present invention can also be said to be that of a display control device that generates signals to enable realization of the above technical ideas. Furthermore, the automatic winder 100 realizes the above technical ideas through the execution of a control program by the control device 4. Therefore, the present invention can also be said to be that of a control program for executing a process to realize the above technical ideas.

According to the sixteenth aspect of the present invention, the display control device generates the signal so as to cause the display section to display the abnormality determination level set by the setting section. Consequently, the reference for determining whether the vibrations are large can be arbitrarily set. According to the seventeenth aspect of the present invention, the display control device generates the signal so as to cause the display section to shift the abnormality determination level following the operation of the setting section, with the graph displayed on the display section. Consequently, the reference for determining whether the vibrations are large can be set while referring to the actual magnitude of the vibration values. According to the eighteenth aspect of the present invention, the control program executes a process so as to cause the display section to display a graph in which a vibration value of each of the winding units is visually arranged side by side and to also display on the graph an abnormality determination level that serves as a reference for determining whether the vibration is large.
