Description

The present invention relates to a winding device.

Conventionally, winding devices have been developed for winding bedding such as down comforters for packaging. One example of such a winding device is disclosed in Patent Document 1.

In the winding device of Patent Document 1, the bedding is folded and stacked, and the folded portion of the bedding is hooked onto one of the retaining bars of a rotating winding member, which is made up of multiple retaining bars arranged in a circle, and the rotating winding member is rotated to wind the bedding into a hollow shape.

JP 2019-151400 A

However, with the winding device of Patent Document 1, the user must first hook the bedding onto the holding bar. This can cause problems in terms of work efficiency, for example, when winding up a large number of pieces of bedding one after another.

In view of the above-mentioned problems, the present invention aims to provide a winding device that can improve the efficiency of winding operations.

The winding device according to the present invention is a winding device that performs a transport process in which an object is placed on a transport path and transported toward a winding shaft, fixes the vicinity of the leading end of the object in the transport direction to the winding shaft, and rotates the winding shaft to wind up the object, and is configured such that at least a portion of the transport path is formed as a movable transport path that moves away from the winding shaft after the transport process. This configuration makes it possible to improve the efficiency of the winding work.

More specifically, the above configuration may be such that, as the winding of the object progresses, the movable transport path moves away from the winding shaft while pressing the object toward the winding shaft. In the above configuration, the winding shaft may be disposed on the upper side near the end of the movable transport path in the transport direction, and the movable transport path moves away from the winding shaft by rotating around the end of the movable transport path in the opposite direction to the transport direction.

In the above configuration, a winding guide that forms a gap between the winding shaft and the winding guide may be fixed to the winding shaft, and the object may be inserted into the gap to fix the vicinity of the leading end of the object in the transport direction to the winding shaft. In the above configuration, the gap may be formed so that the object can be wound around the winding shaft at an angle of 90 degrees or more.

In the above configuration, the winding guide may have a first plate-shaped portion, a second plate-shaped portion having one end connected at an angle of 90 degrees to one end of the first plate-shaped portion, a third plate-shaped portion having one end connected at an angle of 135 degrees to the other end of the second plate-shaped portion, and a fourth plate-shaped portion having one end connected at an angle of 135 degrees to the other end of the second plate-shaped portion, the first plate-shaped portion and the fourth plate-shaped portion facing each other in the direction in which the second plate-shaped portion extends, and the winding shaft may have, in a side view, an arc-shaped portion and a straight portion connecting both ends of the arc-shaped portion, and the straight portion may be fixed to the inner surface near the other end of the first plate-shaped portion, so that the winding shaft is integrated with the winding guide.

In the above configuration, the winding of the object by the winding shaft may be stopped when the end of the object facing in the opposite direction to the transport direction is located immediately above the winding shaft.

In the above configuration, the transport path may have a feed roller that transports the object in the transport direction, and the rotation speed of the feed roller may be slower than the rotation speed of the winding shaft. In the above configuration, the object may be a cushion body formed from a three-dimensional filament assembly.

The winding device of the present invention makes it possible to improve the efficiency of winding operations.

<Overall configuration of winding device>
FIG. 1 is a perspective view of a winding device 1 according to an exemplary embodiment of the present invention, viewed approximately from the right side; FIG. 2 is a perspective view of the winding device 1, viewed approximately from the left side; and FIG. 3 is a perspective view of the winding device 1, viewed approximately from the front side.

The winding device 1 is a device for winding up bedding as an example of a work (target object). In particular, the bedding here is a cushion body used in bed mattresses and the like. More specifically, the cushion body is formed from a three-dimensional filament bond (a three-dimensional mesh structure) obtained by three-dimensionally fusing and bonding filaments made of thermoplastic resin, and is a flexible, approximately plate-like body. Note that the three-dimensional filament bond is publicly known, as disclosed in, for example, JP 2020-26586 A, and therefore a detailed description thereof will be omitted here.

The winding device 1 includes a conveying roller 2, a pair of feed rollers 3, a left side plate 4, a right side plate 5, a pair of feed work sensors 6, a pair of input guides 7, a movable conveying path 8, a winding shaft 9, a winding guide 10, a guide roller 11, an ejection cylinder 12, a feed roller drive mechanism 13, a winding shaft drive mechanism 14, a bag setting jig 15, a winding shaft supporter 16, a lower frame 17, a pair of air cylinders 18, an ejection bar 19, and a winding work sensor 20.

The multiple conveying rollers 2, the pair of feed rollers 3, and the movable conveying path 8 constitute the conveying path 50. The conveying path 50 is a passage for conveying the workpiece in the conveying direction A (forward) indicated by the arrow in Figures 1 and 2.

The multiple transport rollers 2 are arranged from rear to front, and each of them is rotatable around a rotation axis that extends in the left-right direction (axial direction). Each transport roller 2 is sandwiched between a left side plate 4 and a right side plate 5.

The pair of feed rollers 3 specifically consists of an upper feed roller 3A and a lower feed roller 3B. The lower feed roller 3B is arranged adjacent to the front side of the frontmost conveying roller 2 among the multiple conveying rollers 2 (see FIG. 4 described later). The upper feed roller 3A is arranged above the lower feed roller 3B. A gap SS is provided between the upper feed roller 3A and the lower feed roller 3B to insert a workpiece (see FIG. 4). The pair of feed rollers 3 are driven to rotate around a rotation axis extending in the axial direction by a feed roller drive mechanism 13. The feed roller drive mechanism 13 includes a feed motor 131 provided on the right side of the device and a gear box 132 provided on the left side of the device. A clutch is provided between the feed motor 131 and the feed roller 3, and by disengaging this clutch, the feed roller 3 described later can be idling.

The pair of feed work sensors 6 specifically consists of a left work sensor 6A and a right work sensor 6B. The feed work sensor 6 is a sensor that detects that the work is located at the transport start position, which is a position just in front of the pair of feed rollers 3. The pair of input guides 7 consists of a left guide 7A and a right guide 7B, and each guide 7A, 7B can slide on the transport rollers 2 in opposite directions in the left-right direction. In other words, each guide 7A, 7B can move toward or away from each other in the left-right direction, and the sliding position can be adjusted according to the width of the work. The work is sandwiched between the input guides 7 from the left and right and guided while being transported.

The movable transport path 8 is disposed forward of the pair of feed rollers 3 and extends in the front-rear direction. The movable transport path 8 is rotatable about a rotation axis extending in the axial direction located near its rear end (the end opposite the transport direction). A more detailed configuration of the movable transport path 8 will be described later.

The winding shaft 9 is disposed above the transport path 8. The winding shaft 9 is driven to rotate around an axis of rotation extending in the axial direction by a winding shaft drive mechanism 14. The winding shaft drive mechanism 14 includes a winding motor 141 provided on the right side of the device. The winding shaft 9 is a member for winding up the workpiece.

The winding guide 10 is a plate-like member that is fixed to the circumferential surface of the winding shaft 9 and is bent when viewed from the left and right side (Figure 4). The winding guide 10 extends over the entire axial direction of the winding shaft 9. The winding guide 10 is a member that guides the insertion of the tip of the workpiece in the transport direction and fixes the vicinity of the tip in the transport direction to the winding shaft 9.

The multiple guide rollers 11 are each rotatable around a rotation axis that extends in the axial direction, and are arranged in an arc shape around the winding shaft 9 and winding guide 10 when viewed from the left and right side (Figure 4). The guide rollers 11 come into contact with the workpiece to guide it when the number of turns of the workpiece increases during winding.

The winding work sensor 20 is a sensor for detecting that the leading end of the work in the transport direction is located at a predetermined position inside the winding guide 10.

A pair of left and right air cylinders 18 are fixed to the lower frame 17. The air cylinders 18 are connected to the movable transport path 8. When the air cylinders 18 are driven, the movable transport path 8 can rise above the horizontal position. When the air cylinders 18 are not driven, the movable transport path 8 is stopped in the horizontal position.

The winding shaft supporter 16 supports the winding shaft 9. As described below, when the workpiece wound by the winding shaft 9 is discharged to the left, the winding shaft supporter 16 is driven to move downward so as not to interfere with the discharge of the workpiece.

The bag setting jig 15 is a jig for fixing a storage bag for storing workpieces to the winding device 1, and is provided on the left side of the device.

The discharge cylinder 12 can move the discharge bar 19 left and right (axial direction). By moving the discharge bar 19 to the left, the workpiece wound by the winding shaft 9 is discharged into the storage bag fixed to the bag setting jig 15.

The lower frame 17 has casters 17A at the four corners of the lower end. This allows the user to move the reeling device 1 by, for example, pushing it.

<Configuration of movable transport path>
Fig. 4 is a side cross-sectional view of a main part showing a configuration around the movable transport path 8 in the winding device 1. As shown in Fig. 4, the movable transport path 8 has four movable rollers 81A and one fixed roller 81B.

As shown in FIG. 6, the movable conveying path 8 has a frame 82 extending in the front-rear direction, and the movable rollers 81A are sandwiched between the frames 82 in the left-right direction and are held by the frames 82. The movable rollers 81A are aligned in the front-rear direction.

As shown in FIG. 4, one transport roller 2 is arranged adjacent to and in front of the lower feed roller 3B. A fixed roller 81B is arranged adjacent to and in front of the transport roller 2. Four movable rollers 81A are arranged in front of the fixed roller 81B.

The fixed roller 81B is rotatable around a rotation axis extending in the axial direction. The position of the fixed roller 81B is fixed. The movable roller 81A and the frame 82 are integrally rotatable around the rotation axis of the fixed roller 81B. In other words, the movable roller 81A is movable up and down.

As shown in FIG. 4, the winding shaft 9 is disposed on the upper side near the front end of the movable conveying path 8. Also, as shown in FIG. 4, an air cylinder 18 is connected to the front lower end of the frame 82.

<Configuration of the winding guide>
Fig. 5 is a side view of the winding guide 10 and the winding shaft 9 as viewed from the left and right side. As shown in Fig. 5, the winding guide 10 is a plate-like member having a bent shape as viewed from the left and right side, and has a first plate-like portion 101, a second plate-like portion 102, a third plate-like portion 103, and a fourth plate-like portion 104 as an integral part.

The first plate-shaped portion 101 has one end connected to one end of the second plate-shaped portion 102, and the angle between the first plate-shaped portion 101 and the second plate-shaped portion 102 is 90 degrees. The other end of the second plate-shaped portion 102 is connected to one end of the third plate-shaped portion 103, and the angle between the second plate-shaped portion 102 and the third plate-shaped portion 103 is 135 degrees. The other end of the third plate-shaped portion 103 is connected to one end of the fourth plate-shaped portion 104, and the angle between the third plate-shaped portion 104 and the fourth plate-shaped portion 104 is 135 degrees. The first plate-shaped portion 101 and the fourth plate-shaped portion 104 face each other in the direction in which the second plate-shaped portion 102 extends.

The winding shaft 9 has an arc-shaped portion 9A with a diameter D when viewed from the left and right side, and a straight portion 9B connecting both ends of the arc-shaped portion 9A. The straight portion 9B is fixed to the inner surface near the other end of the first plate-shaped portion 101, so that the winding shaft 9 is integrated with the winding guide 10.

A gap S is formed between the winding guide 10 and the winding shaft 9. A workpiece can be inserted into the gap S through an opening SA of the gap S. As shown in FIG. 5, the gap S extends from the opening SA to the rear side of the line segment L2, which is obtained by rotating a line segment L1 connecting the rotation axis position (center position of the arc-shaped portion 9A) of the winding shaft 9 and the outer end of the opening SA by 90 degrees around the rotation axis position, in a left-right side view. This makes it possible to wind the workpiece around the winding shaft 9 by 90 degrees or more around the rotation axis. Therefore, the workpiece can be firmly fixed to the winding shaft 9. Note that the winding guide 10 of this embodiment extends over the entire axial direction of the winding shaft 9, but other shapes may be adopted as long as the workpiece is appropriately fixed. For example, the winding guide 10 may be in a claw shape (the same shape as in FIG. 5 when viewed from the left-right side, but a shape that is shortened in the axial direction of the winding shaft 9), and may be provided only at both axial ends of the winding shaft 9.

<Configuration of bag setting jig>
6 is an enlarged view of a main portion showing the configuration around the bag setting jig 15 in the winding device 1. The bag setting jig 15 has a flange 151 and bag gripping portions 15A to 15C.

The flange 151 is attached to the outer surface of the left side plate 4. The opening 151A of the flange 151 is located to the left of the winding shaft 9 and faces the winding shaft 9 in the left-right direction.

Near the outer circumferential edge of the flange 151, the bag gripping parts 15A to 15C are arranged at equal intervals around a central axis extending in the left-right direction of the flange 151. Each of the bag gripping parts 15A to 15C can be opened and closed freely by a hinge. When the bag gripping parts 15A to 15C are in the open state, there is a space between the flange 151 and the bag gripping parts 15A to 15C to insert a storage bag (bag gripping parts 15B and 15C in FIG. 6 are in the open state). When the bag gripping parts 15A to 15C are in the closed state, there is almost no gap between the flange 151 and the bag gripping parts 15A to 15C, and the storage bag can be gripped between the flange 151 and the bag gripping parts 15A to 15C (bag gripping part 15A in FIG. 6 is in the closed state).

As a result, the storage bag can be fixed to the winding device 1 by opening the bag gripping parts 15A to 15C, attaching the storage bag to the flange 151, and closing the bag gripping parts 15A to 15C.

<Configuration of Discharge Mechanism>
FIG. 7 is an enlarged view of the main part mainly showing the configuration of the bag setting jig 15 in the winding device 1. FIG. 8 is an enlarged view of the main part of the winding device 1 as viewed from the right side. The discharge bar 19, which can be moved in the left-right direction by the discharge cylinder 12 (FIG. 8), is located at an initial position on the back side of the paper in FIG. 7 in the state shown in FIG. 7 and FIG. 8. In the initial position state, the discharge bar 19 is located to the right of the work taken up by the winding shaft 9 (back side of the paper in FIG. 7). The discharge bar 19 moves to the left side of the initial position (front side of the paper in FIG. 7) to push the taken up work towards the bag setting jig 15. As a result, the work is stored in a storage bag set in the bag setting jig 15.

<Processing steps of the winding device>
Next, the processing steps performed by the winding device 1 according to this embodiment will be described with reference to the flowchart shown in Fig. 9. Here, Fig. 10 is a block diagram showing the electrical configuration of the winding device 1 according to this embodiment. As shown in Fig. 10, the winding device 1 has a control unit 30 that controls each unit.

When the process of the flowchart shown in FIG. 9 is started, first in step S1, the control unit 30 determines whether or not a workpiece is detected by the feed workpiece sensors 6A and 6B. If a workpiece is not detected (NO in step S1), step S1 is repeated.

The operator sets a roughly plate-shaped workpiece on the conveyor rollers 2 and pushes the workpiece in the conveying direction toward the feed motor 3. When the leading edge of the workpiece in the conveying direction reaches the conveying start position just before the feed rollers 3, the workpiece is detected by the conveyor work sensors 6A and 6B (YES in step S1). Then, the process proceeds to step S2, where the control unit 30 determines whether a storage bag is set in the bag setting jig 15.

Whether a storage bag is set in the bag setting jig 15 can be determined by, for example, checking whether the bag gripping units 15A to 15C are all in a closed state. The control unit 30 repeats step S2 while a storage bag is not set (NO in step S2).

If the control unit 30 determines that a storage bag is set (YES in step S2), the process proceeds to step S3, where the control unit 30 starts driving the air cylinder 18. As a result, as in step S4, the movable transport path 8 rises from the horizontal position. At this time, as shown in the schematic diagram in FIG. 11, the winding guide 10 is in the initial position with the opening SA facing downward. Then, the movable transport path 8 rotates around the rotation axis J1 of the fixed roller 81B until it comes into contact with the fourth plate-shaped portion 104 of the winding guide 10, and rises from the horizontal position (dashed line in FIG. 11). After rising, the movable transport path 8 continues to be urged upward with a generally constant force by the action of the air cylinder 18 until step S10, which will be described later, is performed.

Then, in step S5, the control unit 30 starts driving the feed motor 131, thereby starting to drive the feed rollers 3 (upper feed roller 3A, lower feed roller 3B). Then, the leading end of the work in the transport direction is pulled into the gap SS (Figure 4) between the pair of feed rollers 3, and the transport process of the work in the transport direction is started.

As a result, as shown in FIG. 11, the workpiece W is transported in the transport direction A, and the transport direction leading end T1 of the workpiece W passes over each roller, in the order shown in FIG. 11, from the transport roller 2 to the fixed roller 81B of the movable transport path 8, and then over the movable roller 81A.

Then, the leading end T1 of the work W in the transport direction enters the gap S between the winding guide 10 and the winding shaft 9 through an opening SA. Then, as shown in FIG. 12, the leading end T1 of the work W in the transport direction reaches a predetermined position P that is rotated further than the line segment L2, which is rotated 90 degrees around the rotation axis J2 of the winding shaft 9 from the aforementioned line segment L1 (FIG. 10). This allows the work W to be wound around the winding shaft 9 near the leading end T1 in the transport direction by more than 90 degrees, as shown in FIG. 12. The specific position of the predetermined position P can be set arbitrarily as long as the leading end T1 of the work W in the transport direction does not unintentionally deviate from the gap S.

After step S5, in step S6, the control unit 30 determines whether or not the workpiece is detected by the winding workpiece sensor 20. When the leading end T1 of the workpiece W in the transport direction reaches a predetermined position P as shown in FIG. 12, the workpiece W is detected by the winding workpiece sensor 20. The winding workpiece sensor 20 is shown in FIG. 8.

When the winding workpiece sensor 20 detects a workpiece (YES in step S6), the process proceeds to step S7, where the control unit 30 stops driving the feed motor 131, thereby stopping the drive of the feed roller 3. This stops the workpiece transport process.

Then, the process proceeds to step S8, where the control unit 30 starts driving the winding motor 141, and starts driving the winding shaft 9. As a result, the winding shaft 9 starts rotating clockwise around the rotation axis J2 when viewed from the left side. At this time, the control unit 30 causes the feed motor 131 (i.e., the feed roller 3) to rotate freely. However, this is not limited to this, and the control unit 30 may also control the rotation speed of the feed roller 3 to be slower than the rotation speed of the winding shaft 9. This makes it possible to transport the workpiece while pulling it in the transport direction, and makes it possible to more sufficiently suppress slackness of the workpiece, etc.

In step S8, as shown in Figure 13, the work W is wound around the winding shaft 9 and winding guide 10. At this time, as shown in Figure 13, as the winding of the work W progresses, the radial dimension of the wound work W gradually increases, and accordingly, it acts to press the movable conveying path 8 downward against the force of the air cylinder 18 described above. At this time, it can also be seen that the movable conveying path 8 moves away from the winding shaft 9 while pressing (applying force) the work W toward the winding shaft 9 by the air cylinder 18.

As a result, the movable conveying path 8 gradually descends while supporting the workpiece W with a roughly constant force. Figure 13 shows that the movable conveying path 8 has rotated and moved around the rotation axis J1 from the position of the movable conveying path 8 in Figure 12 (dashed line) to the position shown by the solid line. This allows the workpiece W to be wound up while being supported by the movable conveying path 8, making it possible to continue winding while preventing the workpiece W from sagging and making winding unstable.

Figure 14 shows a state where winding has progressed further from that shown in Figure 13, with the movable conveying path 8 moving further (downward) from the position shown in Figure 13 (dashed line) to the position shown by the solid line.

Then, in step S9, the control unit 30 stops driving the winding motor 141, thereby stopping the driving of the winding shaft 9. The timing of this stop is preferably set, for example, when the end T2 of the work W in the opposite direction to the transport direction is located near directly above the winding shaft 9, as shown in FIG. 15. If the winding shaft 9 rotates further to the left than shown in FIG. 15 when winding is stopped, the area near the end T2 will be peeled off from the work W, making it difficult to store the work W in the storage bag during the discharge process described below.

To set the timing for winding to stop when end T2 is located near directly above winding shaft 9, end T2 may be detected by a sensor (not shown), for example. Alternatively, the control unit 30 may start measuring time after determining that the feed workpiece sensors 6A, 6B no longer detect the workpiece W, and stop driving the winding shaft 9 when a predetermined time has elapsed.

When the winding process stops in step S9, in step S10 the control unit 30 stops driving the air cylinder 18, thereby lowering the movable transport path 8 to a horizontal position. Then, proceeding to step S11, the control unit 30 drives the discharge cylinder 12 to move the discharge bar 19 leftward from the initial position. This causes the discharge bar 19 to push the workpiece toward the bag setting jig 15, and the workpiece is stored in the storage bag. Note that when the workpiece is discharged by the discharge bar 19, the winding shaft supporter 16 is driven to move downward in advance so as not to impede the discharge of the workpiece.

Then, return to step S1. In the subsequent step S2, it is preferable to determine whether a storage bag has been set by first checking that the bag gripping portions 15A-15C of the bag setting jig 15 are open and then closed. This is because simply checking that they are closed may not indicate that a new storage bag has been set, but rather that the previous storage bag has been set.

After step S11, the worker sets a new storage bag, then sets a new work W on the conveying path 50 and pushes it toward the feed rollers 3, and proceeds to step S3, where the conveying process begins.

As described above, the winding device 1 according to this embodiment can automatically transport, wind, and discharge the workpiece. This allows the series of operations of winding up the workpiece to make it compact and storing it in a storage bag to be carried out very efficiently, and the efficiency of the operations can be significantly improved even when there is a large amount of workpiece.

＜Other＞
As described above, the winding device 1 is a winding device that performs a transport process in which the workpiece is placed on the transport path 50 and transported toward the winding shaft 9, fixes the vicinity of the leading end of the workpiece in the transport direction to the winding shaft 9, and rotates the winding shaft 9 to wind the workpiece, and a part of the transport path 50 is formed as a movable transport path 8 that moves away from the winding shaft 9 after the transport process. Therefore, the transport path 50 transports the workpiece and makes it easy to fix it to the winding shaft 9, but moves away from the winding shaft 9 so as not to hinder the winding of the workpiece. In this way, the winding device 1 is devised to make it possible to improve the efficiency of the winding operation.
