Description

Automatic winder

Technical Field

The present invention relates to an automatic winder. More specifically, the present invention relates to a state display unit for displaying the state of equipment included in an automatic winder.

Background

Patent document 1 is japanese patent application laid-open No. 2010-269915.

The automatic winder of patent document 1 includes a winding unit that winds a plurality of yarns of a yarn feeding bobbin to form a package. Each winding unit is provided with an alarm portion as a lamp or a buzzer. Patent document 1 discloses that an abnormality notified by an alarm unit is a doffing error of a doffing device in addition to a defective rotation of a package.

In the automatic winder of patent document 1, when an abnormality occurs and the winder stops, the alarm unit is turned on, but the alarm unit is turned off in a state other than that. For this reason, for example, it is not clearly discriminated whether the doffing device stops in the middle of a series of doffing operations (operation cycle) or stops after the doffing device ends a series of doffing operations. Therefore, the operator cannot grasp the state of the doffing device at a glance. The problem is not limited to the doffing device, and the same problem also exists in other devices provided in an automatic winder, for example, a package conveyor.

Disclosure of Invention

The present invention has been made in view of the above circumstances, and a main object thereof is to provide an automatic winder in which an operator can easily grasp the operation state of a doffer or a package conveyor at a glance.

The problems to be solved by the present invention are as described above, and means for solving the problems and effects thereof will be described below.

According to an aspect of the present invention, there is provided an automatic winder having the following structure. That is, the automatic winder includes a plurality of winding units, doffing devices, package conveyors, and operation status display panels. The winding unit unwinds the yarn from the yarn feeding bobbin and winds the unwound yarn to form packages, respectively. The doffing device doffs the package formed by the winding unit. The package conveyor conveys the packages doffed by the doffing device. The operation state display panel is provided on the doffing device and the package conveyor. The operation state display panel includes a segmented display portion including a plurality of columns and a plurality of rows of segments. The segment display unit of the operation state display panel displays an operation state of at least one of the doffing device and the package conveyor by a regular lighting and extinguishing pattern.

Thus, since the operation state is displayed for at least one of the doffing device and the package conveyor, for example, the operator can easily confirm whether the device to be operated is temporarily stopped during the operation or stopped after the operation is completed.

In the automatic winder, it is preferable that the segment display unit of the operation state display panel is a seven-segment display.

This suppresses the number of segments and enables various displays.

In the automatic winder, the following structure is preferable. That is, the winding unit includes a unit operation panel for controlling the operation of the equipment provided in the winding unit. The unit operation panel includes a segmented display portion including a plurality of columns and a plurality of rows of segments. The segment display portion of the operation state display panel and the segment display portion of the unit operation panel have the same configuration.

In this way, at least a part of the components can be shared by the unit operation panel and the operation state display panel, and therefore, the cost can be reduced.

In the automatic winder, the following structure is preferable. Namely, an automatic winder preparing device and a bobbin conveyor. The preparation device pre-processes the yarn feeding bobbin so that the winding unit can process the yarn feeding bobbin. The bobbin conveyor supplies the yarn feeding bobbin pretreated by the preparation device to the winding unit. The operation state display panel is further provided on at least one of the preparation device and the bobbin conveyor, and the segment display portion of the operation state display panel further displays an operation state of at least one of the preparation device and the bobbin conveyor.

Thus, since the operation state is displayed for at least one of the preparation device and the bobbin conveyor, for example, the operator can easily confirm whether the operation is temporarily stopped during the operation or stopped after the operation is completed.

In the automatic winder, the following structure is preferable. That is, the automatic winder includes a supply device that supplies the yarn feeding bobbin to the bobbin conveyor. The operation state display panel is further provided in the supply device, and the segment display portion of the operation state display panel further displays an operation state of the supply device.

Thus, the operation state display panel displays the operation state of the supply device, so that the operator can easily confirm whether the supply device is temporarily stopped during a work or stopped after the work is completed, for example.

In the automatic winder, the following structure is preferable. That is, the operation state display panel is provided on the package conveyor. The segment display part of the operation state display panel arranged on the package conveyor displays the operation state of the package conveyor.

Thus, since the operating state of the package conveyor is displayed, for example, the operator can easily confirm whether the operation is temporarily interrupted during the work or stopped after the work is completed.

In the automatic winder, it is preferable that the segment display unit provided on the operation state display panel of the package conveyor displays a rotation of the lighting position by making the lighting and extinguishing timings different for each segment when the package conveyor is in operation.

Thus, the concept of the operation of the package conveyor and the rotation of the lighting position are similar, so that the operator can intuitively grasp the operation of the package conveyor.

In the automatic winder, the following structure is preferable. That is, the automatic winder includes a package shutter that can switch between a first state in which the package can be moved from the winding unit to the package conveyor and a second state in which the package cannot be moved from the winding unit to the package conveyor. The single operation state display panel displays the operation state of the package conveyor and the operation state of the package gate.

Thus, the operating states of the two devices performing a series of operations are displayed on the single operating state display panel, and thus the operator can grasp the operating states of the two devices performing a series of operations by observing only the single operating state display panel.

In the automatic winder, the following structure is preferable. That is, the automatic winder includes a package shutter that can switch between a first state in which the package can be moved from the winding unit to the package conveyor and a second state in which the package cannot be moved from the winding unit to the package conveyor. The segment display unit of the operation state display panel for displaying the operation state of the roll-up door displays that the lighting position moves in the up-down direction by making the lighting and extinguishing timings different in units of the segments.

Thus, the concept of the operation of the package shutter and the movement of the lighting position in the up-down direction are similar, so that the operator can intuitively grasp the operation of the package shutter.

In the automatic winder, it is preferable that when the seven-segment display of the operation state display panel is turned on and off in a regular pattern, the number of the turned-on segments is the same for each pattern.

Thus, a sense of unity can appear between the patterns.

In the automatic winder, the following structure is preferable. That is, the segment display unit displays an on character by turning on or off the segment, thereby indicating that the device to be operated is operating, and the segment display unit displays an off character by turning on or off the segment, thereby indicating that the device to be operated is stopped.

Thus, the operator can grasp at a glance whether the apparatus is in operation.

Detailed Description

Next, embodiments of the present invention will be described with reference to the drawings.

The automatic winder 100 shown in fig. 1 includes an automatic winder main body 1, a bobbin preparation system 2, and a supply device 3.

As shown in fig. 2, the automatic winder main body 1 mainly includes a plurality of winding units 1a arranged in an array, a control box 85, and a doffing device 17. As shown in fig. 1, a bobbin conveyor 4 for automatically conveying a yarn feeding bobbin 12 to each winding unit 1a is formed in the automatic winder main body 1. Each winding unit 1a unwinds the yarn 10 from the yarn feeding bobbin 12 and winds the unwound yarn 10 around the winding tube while traversing the yarn to form a package 15.

The control box 85 is provided with a centralized management device 91. The central management device 91 can communicate with each winding unit 1a. The centralized management device 91 can centrally manage information of each winding unit 1a and the like. As shown in fig. 2, the centralized management apparatus 91 includes a display 92, an input unit 93, and a main control unit 94.

The display 92 displays information on the operation condition and/or yarn quality of each winding unit 1a by an appropriate operation of an operator. The input unit 93 includes a plurality of input keys. The input unit 93 is used for an operator to select information to be displayed on the display 92. The input unit 93 receives settings of information on various operating conditions and/or yarn qualities of the winding units 1a and settings of operations of various devices of the automatic winder 100.

The doffing device 17 shown in fig. 2 moves to a position corresponding to one winding unit 1a of the plurality of winding units 1a when the package 15 is fully wound (a state in which a predetermined amount of the yarn 10 is wound) in the winding unit 1a. The doffing device 17 reaching the winding unit 1a can automatically take down the full package 15 and doff and place a new winding tube.

An operation state display panel 80 is provided on the front side of the doffing device 17. The operation state display panel 80 displays the operation state of the doffing device 17. The display operation state indicates whether or not the doffing device 17 is in operation. The operation is a period from after the instruction of the operation is received (or after the operation is started) to the end. In the case of the doffing device 17, the operation corresponds to the period from the time when the request for doffing is received to the time when the doffing operation is completed (the middle of the operation cycle). After the start of the doffing operation, the doffing device 17 is operated in a state of being temporarily stopped in order to wait for the completion of the operation of the other equipment. Therefore, by providing the operation state display panel 80 to the doffing device 17, the operator can easily grasp whether the doffing device 17 is in operation (further, whether the operation is temporarily interrupted or the doffing operation is ended and stopped). The above description of the operation state is applicable not only to the doffer 17 but also to other devices described below.

As shown in fig. 3, the package 15 fully wound in the winding unit 1a is recovered by the package conveyor 52. Specifically, the package 15 that is fully wound and removed by the doffing device 17 moves obliquely downward toward the package conveyor 52 while rolling along the conveying surface 50.

The conveying surface 50 is provided with a package shutter 51. As shown in fig. 3, the roll-up door 51 is capable of switching states between a first state (upper in fig. 3) and a second state (lower in fig. 3). In the first state, since the package shutter 51 protrudes with respect to the conveying surface 50, the movement of the package 15 from the winding unit 1a to the package conveyor 52 is prevented. In the second state, the package shutter 51 moves downward from the first state, and thus the protrusion of the package shutter 51 with respect to the conveying surface 50 disappears. As a result, in the second state, the movement of the package 15 from the winding unit 1a to the package conveyor 52 is allowed. In the present embodiment, one package shutter 51 is provided for each set of predetermined amount of winding units 1a. However, the package shutter 51 may be provided for each winding unit 1a, or one package shutter 51 may be provided for all the winding units 1a.

The package conveyor 52 includes a motor, a pulley, and a belt, not shown, and moves the belt by driving the pulley with the driving force of the motor. The direction of movement of the package conveyor 52 is the same as the direction in which the winding units 1a are aligned, and the direction of movement of the packages 15 is the same as the axial direction.

After the package conveyor 52 starts the conveyance of the package 15, it stops when the package 15 reaches a predetermined position (for example, an end in the conveyance direction). The operator collects the package 15 placed on the package conveyor 52 and puts it into a predetermined collection box. The stop timing of the package conveyor 52 may be stopped after a time from driving the package conveyor 52 to reaching a predetermined position has elapsed, or a sensor for detecting the package 15 may be provided at the predetermined position. This can suppress the package 15 from falling off the package conveyor 52.

The package conveyor 52 is provided with the above-described operation state display panel 80. In the present embodiment, an operation state display panel 80 is provided at the end portion on the downstream side in the conveying direction of the package conveyor 52. However, the operation state display panel 80 may be provided at a position other than the end portion on the downstream side of the package conveyor 52. An operation state display panel 80 provided on the package conveyor 52 displays the operation states of the package shutter 51 and the package conveyor 52.

Here, when the package conveyor 52 simultaneously conveys two packages 15, the package conveyor 52 is stopped at the timing when the first package 15 is conveyed to the predetermined position. In this state, the package conveyor 52 waits for the first package 15 to be recovered by the operator, and the operation of the package conveyor 52 is stopped. However, the package conveyor 52 conveys the second package 15 after the first package 15 is recovered, and thus does not mean that the operation of the package conveyor 52 is completed and stopped. In this state, since the package conveyor 52 is in operation, the operation state display panel 80 displays that the package conveyor 52 is in operation. Therefore, the operator can grasp at a glance whether the package conveyor 52 is in operation (further, whether the operation is temporarily interrupted or the conveying operation of the package 15 is ended and stopped) by looking at the operation state display panel 80.

Next, the winding unit 1a will be described in detail with reference to fig. 2. As shown in fig. 2, the winding unit 1a is configured to unwind the yarn 10 of the yarn feeding bobbin 12 and wind the unwound yarn 10 around a winding tube of the winding unit 22 while traversing the yarn to form a package 15. The winding section 22 includes a cradle 31 and a winding drum 30.

The cradle 31 rotatably supports the winding tube or package 15. The cradle 31 can bring the outer periphery of the supported package 15 into contact with the outer periphery of the winding drum 30.

The take-up drum 30 traverses the yarn 10 on the surface of the package 15 and rotates the package 15. In a state where the outer periphery of the package 15 is brought into contact with the winding drum 30, the winding drum 30 can be driven to rotate by rotation driving. A spiral traverse groove is formed in the outer peripheral surface of the winding drum 30, and the yarn 10 unwound from the yarn feeding bobbin 12 is wound around the surface of the package 15 while being traversed by the traverse groove with a constant width. Thereby, the package 15 having a constant package width can be formed.

The winding unit 1a includes a bobbin placement section 20 that supports the yarn feeding bobbin 12, and a winding section 22 that winds the yarn 10. A path of travel of the yarn 10 is formed between the bobbin placement section 20 and the winding section 22. The winding unit 1a includes, in the middle of the travel path, from the bobbin placement section 20 side toward the winding section 22 side: an unwinding assisting device 23, a tension applying device 25, a jointing device 26, and a yarn quality measuring device 27.

The unwinding assisting device 23 assists in unwinding the yarn 10 from the yarn feeding bobbin 12. The unwinding assisting device 23 is provided with a movable member. The movable member swings the yarn 10 unwound from the yarn feeding bobbin 12 and contacts a balloon formed on the upper portion of the yarn feeding bobbin 12. The unwinding assisting device 23 appropriately controls the size of the balloon by changing the position of the movable member.

The tension applying device 25 applies a predetermined tension to the advancing yarn 10. The tension applying device 25 of the present embodiment is configured as a gate type in which movable comb teeth are arranged with respect to fixed comb teeth. The movable-side comb teeth are rotatable by a rotary solenoid so that the comb teeth are engaged or disengaged.

The yarn quality measuring device 27 monitors the thickness of the yarn 10 and detects yarn defects such as knots. A cutter, not shown, for immediately cutting the yarn 10 when the yarn quality measuring device 27 detects a yarn defect is disposed in the vicinity of the yarn quality measuring device 27.

The yarn joining device 26 joins the lower yarn on the yarn feeding bobbin 12 side and the upper yarn on the package 15 side when the yarn 10 is in the broken state. A lower yarn guide tube 28 for capturing the lower yarn on the yarn feeding bobbin 12 side and guiding the yarn to the yarn splicing device 26, and an upper yarn guide tube 29 for capturing the upper yarn on the package 15 side and guiding the yarn to the yarn splicing device 26 are provided on the lower side and the upper side of the yarn splicing device 26. The case where the yarn 10 is broken includes, for example, a case where the yarn quality measuring device 27 detects a yarn defect and cuts the yarn 10 with a cutter, a case where the yarn 10 being unwound from the yarn feeding bobbin 12 is cut, a case where the yarn feeding bobbin 12 is replaced, and the like. The yarn joining device 26 of the present embodiment uses compressed air to twist the upper yarn and the lower yarn, and the like, to join the yarns.

In the above configuration, each winding unit 1a of the automatic winder main body 1 can unwind the yarn 10 from the yarn feeding bobbin 12 supported by the bobbin placement section 20 and wind the yarn around the winding tube, thereby forming the package 15 having a predetermined length.

Each device included in the winding unit 1a is controlled by a unit control unit 95 shown in fig. 2 and 4. The unit control unit 95 is provided for each winding unit 1a. The unit control unit 95 can communicate with the centralized management apparatus 91.

A unit operation panel 96 is provided on the front side of the winding unit 1a. The unit operation panel 96 is used to control the operation of the equipment provided in the winding unit 1a. The specific configuration of the unit operation panel 96 will be described later.

The spinning machine 40 shown in fig. 1 winds the yarn 10 produced by drawing and twisting the roving around a bobbin to form the yarn feeding bobbin 12. The spinning machine 40 forms a header yarn for winding the yarn 10 around the axial end of the yarn feeding bobbin 12, thereby preventing the yarn 10 from being wound around surrounding members.

The following structure exists as a mechanism for supplying the yarn feeding bobbin 12 around which the yarn spun by the spinning machine 40 is wound to the automatic winder 100. A mechanism for supplying the yarn feeding bobbin 12 removed from the spinning frame 40 by an operator to the automatic winder 100 by using the supply device 3 shown in fig. 1. And a mechanism for directly supplying the yarn feeding tube 12 removed from the spinning frame 40 by an operator to the magazine type yarn feeding tube supply mechanism provided in each winding unit 1a of the automatic winder 100. Further, there is a mechanism in which the spinning frame 40 and the automatic winder 100 are connected by a conveyor, and the yarn feeding bobbin 12 is conveyed from the spinning frame 40 to the automatic winder 100 by the conveyor. In the present embodiment, the yarn feeding bobbin 12 is fed to the automatic winder 100 by the feeding device 3 shown in fig. 1. The feeder 3 places yarn feeding bobbins 12 fed from the spinning machine 40 one by one on the transport tray 16. The transport tray 16 supports the yarn feeding bobbin 12 in a substantially upright state. The supply device 3 is provided with the operation state display panel 80. An operation state display panel 80 provided in the supply device 3 displays the operation state of the supply device 3.

As described above, the yarn feeding bobbin 12 is conveyed to the winding unit 1a via the bobbin conveyor 4 in a state of being placed on the conveying tray 16, and the yarn 10 is unwound by the winding unit 1a. The yarn feeding bobbin 12 from which the yarn 10 is unwound is discharged from the winding unit 1a via the bobbin conveyor 4 while being placed on the conveying tray 16. The bobbin conveyor 4 is provided with the operation state display panel 80. An operation state display panel 80 provided on the bobbin conveyor 4 displays the operation state of the bobbin conveyor 4.

The bobbin preparation system 2 is disposed between the automatic winder main body 1 and the supply device 3. The bobbin preparation system 2 includes a preparation device 8. The preparation device 8 pre-processes the yarn feeding bobbin 12 so that the winding unit 1a can process the yarn feeding bobbin 12. The preparation device 8 unwinds the header yarn of the yarn feeding bobbin 12 to free the yarn end. The preparation device 8 captures the yarn end which is free, pulls the captured yarn end from the yarn feeding bobbin 12, and blows the yarn end to the vicinity of the tip end of the yarn feeding bobbin 12. Then, by rotating the yarn feeding bobbin 12, the yarn end is wound around the upper portion of the core tube of the yarn feeding bobbin 12. The pretreatment of the yarn feeding bobbin 12 is completed. In addition, some of the above-described pretreatment may be omitted. The preparation device 8 is provided with the operation state display panel 80. An operation state display panel 80 provided in the preparation device 8 displays the operation state of the preparation device 8.

The operating state display panel 80 is provided in the supply device 3, the bobbin conveyor 4, and the preparation device 8, so that an operator can grasp the operating state of the apparatus at a glance.

Next, the operation state display panel 80 will be mainly described with reference to fig. 5.

As shown in fig. 5, the operation state display panel 80 includes a segment display 81 and an operation key group 82. The operation key group 82 includes an upper key 82a, a lower key 82b, and a center key 82c.

The segmented display 81 is a display in which segments are arranged in a plurality of rows and a plurality of columns. The segment display unit 81 can individually turn on or off each segment in response to an instruction from the outside. The arrangement method of the segments of the present embodiment is general, in which the segments are arranged in a shape similar to the shape of the arabic numeral 8, and by switching on/off of the segments, one-digit arabic numerals, a part of letters, or the like can be displayed.

In the present embodiment, three seven-segment displays are arranged side by side, but one, two, or four or more seven-segment displays may be arranged side by side. The segment display 81 is not limited to seven segments, and may be of different layouts as long as the segments are arranged in a plurality of rows and a plurality of columns. For example, rectangular or circular dots may be arranged vertically and horizontally with a uniform width.

The operation key group 82 is used to instruct the devices (doffer 17, package shutter 51, package conveyor 52, supply device 3, bobbin conveyor 4, and preparation device 8) whose operation states are displayed on the operation state display panel 80. The up key 82a and the down key 82b are used for selecting, for example, job contents or job objects. The center key 82c is used, for example, to execute the selected job content or job object. The operation key group 82 shown in fig. 5 is an example, and keys may be added, changed, or omitted.

For example, when the package shutter 51 is instructed by using the operation key group 82, the operation of the package shutter 51 can be selected by using the upper key 82a and the lower key 82 b. In the present embodiment, since the package shutter 51 is provided for each set of the predetermined amount of the winding units 1a, the set of objects can be selected using the upper key 82a and the lower key 82 b. When the package shutter 51 is provided in units of one winding unit 1a, the winding unit 1a to be selected can be selected using the upper key 82a and the lower key 82 b.

In addition, when the bobbin conveyor 4 is instructed using the operation key group 82, switching of the path of the bobbin conveyor 4 can be instructed. For example, the switch position of the object can be selected using the up key 82a and the down key 82 b. The use example of the operation key group 82 is an example, and other instructions may be given using the operation key group 82.

The operation state display panel 80 provided in the doffing device 17 switches the display mode of the segment display unit 81 in response to a command from the doffing device 17. In addition, a signal based on an operation performed on the operation key group 82 is transmitted to the doffing device 17. In other words, the doffing device 17 and the operation state display panel 80 communicate directly (the same applies to other devices). Instead, the device to be connected and the operation state display panel 80 may communicate with each other via the central management apparatus 91.

In the present embodiment, at least a part of the operating state display panel 80 and the unit operation panel 96 is shared. Specifically, the housing, the segment display 81, the operation key group 82, and the substrate for operating them are shared. The common use of the parts means that the respective parts have the same structure (the same specification). By sharing the parts, the purchase cost of the product can be reduced, or the inventory management cost can be reduced. In particular, since the segment display 81 and the substrate have high versatility, they are shared, whereby the cost can be reduced and the influence on convenience and operability can be suppressed. The operation state display panel 80 and the unit operation panel 96 may not include common components.

Next, the lighting/extinguishing pattern of the segment display portion 81 will be described with reference to fig. 6 to 8.

Fig. 6 is a diagram showing a rotation display by turning on/off each segment of the segment display unit 81. As described above, the segment display portion 81 includes three seven-segment displays arranged side by side in the lateral direction. Therefore, the segment display 81 has a horizontally long display area having an approximately rectangular shape. The segment display unit 81 can display (rotate display) that the lighting position appears to rotate by moving the lighting position along the side (outline) of the approximate rectangle. Specifically, first, a segment of a predetermined amount (three in fig. 6) continuous to the sides (outline) of the approximate rectangle is turned on, and the other segments are turned off. Then, the segment at the upstream end in the rotation direction of the lighted segment is turned off, and the segment at the downstream side in the rotation direction is lighted. By repeating this process at predetermined time intervals, the segment display unit 81 can perform rotation display. In addition, as shown in fig. 6, even if the lighting/extinguishing pattern is switched, the number of lighted segments is the same number (in fig. 6, the number of lighting is always three). The number of lighted segments does not change, whereby a sense of unity can occur between patterns, or an impression that the lighted position is moving can be given.

A general rotation display indicates a case where a device for indicating an object is in motion. Accordingly, while the operating state display panel 80 displays that the operating state devices (the doffing device 17, the package shutter 51, the package conveyor 52, the supply device 3, the bobbin conveyor 4, and the preparation device 8) are in operation, the rotating display may be performed on the segment display portion 81. In particular, since the package conveyor 52 and the bobbin conveyor 4 convey the packages 15 or the yarn feeding bobbin 12 by rotation of the pulleys, the affinity with the rotation display is high. Therefore, the operator who has seen the rotation display can intuitively grasp that the package conveyor 52 or the bobbin conveyor 4 is in operation. The direction in which the rotation display of the segment display portion 81 provided on the operation state display panel 80 of the package conveyor 52 changes corresponds to the driving direction (rotation direction) of the package conveyor 52. This is specifically described with reference to fig. 3 and 6. In fig. 3, when an operator located on the front surface of the operation state display panel 80 views the package conveyor 52, the package conveyor 52 is driven to rotate clockwise as indicated by an arrow. As shown in fig. 6, the rotation display of the segment display portion 81 is similarly changed clockwise. Accordingly, since the affinity between the driving of the package conveyor 52 and the display of the segment display 81 is high, the operator can grasp the operation of the package conveyor 52 more intuitively.

In the present embodiment, three seven-segment displays are used for the rotation display, but one, two, or four or more seven-segment displays may be used for the rotation display in the same order.

Fig. 7 is a diagram showing up-and-down movement display by turning on/off each segment of the segment display unit 81. The seven-segment display includes three bar-shaped segments arranged in the up-down direction. Therefore, by switching the on/off of the segments of the bar shape, a display (up-down movement display) in which the on position appears to move up and down can be performed. Specifically, the uppermost (or lowermost) bar-shaped segment is first lighted. Then, the uppermost (or lowermost) bar-shaped segment is extinguished and the central bar-shaped segment is lit. Then, the segment of the bar shape located at the center is extinguished and the segment of the bar shape located at the lowest (or uppermost) is lit. By repeating the above processing, the segment display unit 81 can perform up-and-down movement display. In addition, as shown in fig. 7, even if the lighting/extinguishing pattern is switched, the number of lighted segments is the same (in fig. 7, the number of lighting is always three).

In the present embodiment, the segment display unit 81 includes three seven-segment displays arranged side by side in the lateral direction. Therefore, by turning on/off the respective bar-shaped segments of the three seven-segment displays at the same timing, the segment display portion 81 can perform up-down movement display using the three seven-segment displays.

The up and down movement display is for any object movement from top to bottom, or from bottom to top. Therefore, for example, the affinity with the operation (switching between the first state and the second state) of the package shutter 51 is high. The operation state display panel 80 shown in fig. 3 displays the operation states of both the package shutter 51 and the package conveyor 52. Therefore, the operation state display panel 80 is required to distinguish between the case where the package shutter 51 is in operation and the case where the package conveyor 52 is in operation. Therefore, the operation state display panel 80 performs up-and-down movement display when the package shutter 51 is in operation, and performs rotation display when the package conveyor 52 is in operation. By using a plurality of displays separately in this way, the operating states of a plurality of devices can be displayed on one operating state display panel 80.

Specifically, when the operator instructs the package 15 to be recovered, first, the segment display unit 81 performs up-and-down movement display. Then, when the package 15 reaches the package conveyor 52, the segment display unit 81 performs a rotation display. Thus, the operator can know the state of the package 15 being recovered by merely viewing the operation state display panel 80. The switching from the vertical movement display to the rotation display can be performed by time, for example. That is, after the instruction of the operator or after the operation of the package shutter 51, the count is started at the same time as the up-down movement display is started, and the rotation display is switched to the rotation display at the time when the count reaches the predetermined value. The switching from the up-down movement display to the rotation display is not limited to time. For example, the display may be switched from the up-down movement display to the rotation display, triggered by detection of the package 15 by a sensor or the like provided on the package conveyor 52 side.

The up-and-down movement display is not limited to the operation status of the package shutter 51, and may be used to indicate the operation status of other devices. In the present embodiment, three seven-segment displays are used for the rotation display, but one, two, or four or more seven-segment displays may be used for the rotation display in the same order.

Fig. 8 is a diagram showing on/off display by turning on/off each segment of the segment display unit 81. The seven-segment display is capable of displaying a portion of letters in addition to numbers. The segment display unit 81 of the present embodiment includes three seven-segment displays arranged side by side in the lateral direction. Thus, three letters can be displayed. Therefore, as shown in fig. 8, the segment display section 81 can display "on" and "off".

When the on/off display is used, the segment display unit 81 performs the on display when the target equipment (doffer 17, package shutter 51, package conveyor 52, supply device 3, bobbin conveyor 4, preparation device 8) is in operation. When the device to be operated is not in operation, the segment display unit 81 performs off display. on/off shows a high affinity for all devices.

The above-described regular lighting and extinguishing patterns shown in fig. 6 to 8 are examples, and other patterns may be used to indicate the operation states of the respective devices. For example, the segment display unit 81 may display whether or not the operation is in progress by lighting or blinking a predetermined number or character.

As described above, the automatic winder 100 of the present embodiment includes the plurality of winding units 1a, the doffing device 17, the package conveyor 52, and the operation state display panel 80. The winding unit 1a unwinds the yarn from the yarn feeding bobbin 12 and winds the unwound yarn to form packages 15, respectively. The doffing device 17 performs doffing by taking down the package 15 formed by the winding unit 1a. The package conveyor 52 conveys packages 15 doffed by the doffing device 17. The operation state display panel 80 is provided on the doffing device 17 and the package conveyor 52. The operation state display panel 80 includes a segmented display portion 81 including a plurality of columns and a plurality of rows of segments. The segment display unit 81 of the operation state display panel 80 displays the operation state of at least one of the doffing device 17 and the package conveyor 52 by the regular lighting and extinguishing pattern.

Thus, since the operation state is displayed for at least one of the doffer 17 and the package conveyor 52, for example, the operator can easily confirm whether the device to be operated is temporarily stopped during the operation or the operation is ended and stopped.

In the automatic winder 100 of the present embodiment, the segment display 81 of the operation state display panel 80 is a seven-segment display.

This suppresses the number of segments and enables various displays.

In the automatic winder 100 of the present embodiment, the winding unit 1a includes a unit operation panel 96 for controlling the operation of the equipment included in the winding unit 1a. The unit operation panel 96 includes a segmented display portion 81 including a plurality of columns and a plurality of rows of segments. The segment display 81 of the operation state display panel 80 and the segment display 81 of the unit operation panel 96 have the same configuration.

In this way, at least a part of the components can be shared by the unit operation panel 96 and the operation state display panel 80, so that the cost can be reduced.

The automatic winder 100 of the present embodiment includes a preparation device 8 and a bobbin conveyor 4. The preparation device 8 pre-processes the yarn feeding bobbin 12 so that the winding unit 1a can process the yarn feeding bobbin 12. The bobbin conveyor 4 supplies the yarn feeding bobbin 12 pretreated by the preparation device 8 to the winding unit 1a. The operation state display panel 80 is further provided on at least one of the preparation device 8 and the bobbin conveyor 4, and the segment display portion 81 of the operation state display panel 80 further displays the operation state of at least one of the preparation device 8 and the bobbin conveyor 4.

Thus, since the operation state is displayed for at least one of the preparation device 8 and the bobbin conveyor 4, for example, the operator can easily confirm whether the operation is temporarily stopped during the operation or stopped after the operation is completed.

The automatic winder 100 of the present embodiment includes a supply device 3 that supplies the yarn feeding bobbin 12 to the bobbin conveyor 4. The operation state display panel 80 is further provided to the supply device 3, and the segment display portion 81 of the operation state display panel 80 further displays the operation state of the supply device 3.

Thus, since the operation state display panel 80 displays the operation state of the supply device 3, the operator can easily confirm whether the supply device 3 is temporarily stopped during a work or stopped after the work is completed, for example.

In the automatic winder 100 of the present embodiment, the operation state display panel 80 is provided on the package conveyor 52. The segment display unit 81 provided on the operation state display panel 80 of the package conveyor 52 displays the operation state of the package conveyor 52.

Thus, since the operation state of the package conveyor 52 is displayed, for example, the operator can easily confirm whether the operation is temporarily stopped during the work or stopped after the work is completed.

In the automatic winder 100 of the present embodiment, when the package conveyor 52 is in operation, the segment display unit 81 provided on the operation state display panel 80 of the package conveyor 52 displays that the lighting position is rotated by making the lighting and extinguishing timings different in units of segments.

Thus, since the operation of the package conveyor 52 is similar to the concept of rotation at the lighting position, the operator can intuitively grasp the operation of the package conveyor 52.

The automatic winder 100 of the present embodiment includes a package shutter 51 capable of switching between a first state in which the package 15 can be moved from the winding unit 1a to the package conveyor 52 and a second state in which the package 15 cannot be moved from the winding unit 1a to the package conveyor 52. The single operation state display panel 80 displays the operation state of the package conveyor 52 and the operation state of the package shutter 51.

Accordingly, since the operation states of the two devices performing a series of operations are displayed on the single operation state display panel 80, the operator can grasp the operation states of the two devices performing a series of operations by merely viewing the single operation state display panel 80.

The automatic winder 100 of the present embodiment includes a package shutter 51 capable of switching between a first state in which the package 15 can be moved from the winding unit 1a to the package conveyor 52 and a second state in which the package 15 cannot be moved from the winding unit 1a to the package conveyor 52. The segment display unit 81 of the operation state display panel 80, which displays the operation state of the package shutter 51, displays that the lighting position moves in the up-down direction by making the lighting and extinguishing timings different in units of segments.

Thus, since the concept of the operation of the package shutter 51 and the movement of the lighting position in the up-down direction are similar, the operator can intuitively grasp the operation of the package shutter 51.

In the automatic winder 100 of the present embodiment, the segment display unit 81 displays on characters by turning on or off segments, thereby indicating that the target device is operating. The segment display unit 81 displays an off character by turning on or off the segment, thereby indicating that the device to be operated is stopped.

In the automatic winder 100 of the present embodiment, when the seven-segment display of the operation state display panel 80 is turned on and off in a regular pattern, the number of the turned-on segments is the same for each pattern.

Thereby, a sense of unity can appear between the patterns.

Thus, the operator can grasp at a glance whether the apparatus is in operation.

While the preferred embodiments of the present invention have been described above, the above-described structure can be changed as follows.

The operation state display panel 80 of the above embodiment includes the segment display portion 81 and the operation key group 82, but the operation key group 82 may be omitted. The operation state display panel 80 may be provided with a member other than the segment display 81 and the operation key group 82.

The operation state display panel 80 may be provided to at least one of the doffer 17 and the package conveyor 52, and the operation state display panel 80 other than this may be omitted. In the present embodiment, the operating state display panel 80 provided on the package conveyor 52 displays the operating states of both the package shutter 51 and the package conveyor 52, but only one of the operating states may be displayed.

In the above embodiment, although the rotation display, the up-down movement display, and the on/off display have been described as examples of the display performed by the operation state display panel 80, other displays than the above may be performed. For example, the segment display portion 81 of the operation state display panel 80 may perform a left-right movement display in which the lighting position is moved in the left or right direction.
