Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the winding device of Patent Document 1, the user needs to first hook the bedding on the holding bar. Therefore, for example, when performing an operation of sequentially winding a large number of bedding, there may be a problem in terms of work efficiency and the like.

[0006] In view of the above problems, an object of the present invention is to provide a winding device capable of improving the efficiency of the winding operation.

Means for Solving the Problems

[0007] The winding device according to the present invention performs a conveying process of placing an object on a conveying path and conveying it toward a winding shaft, fixes the vicinity of the leading end portion in the conveying direction of the object to the winding shaft, and rotates the winding shaft to wind the object. At least a part of the conveying path is configured as a movable conveying path that moves away from the winding shaft after the conveying process. According to this configuration, it is possible to improve the efficiency of the winding operation.

[0008] More specifically, as the above configuration, the movable conveying path may be configured to move away from the winding shaft while pressing the object toward the winding shaft as the winding of the object progresses. Further, in the above configuration, the winding shaft may be disposed above the vicinity of the end portion on the conveying direction side of the movable conveying path, and the movable conveying path may be configured to move away from the winding shaft by rotation around the end portion on the opposite side in the reverse direction of the conveying direction as the rotation axis.

[0009] Further, in the above configuration, a winding guide that forms a gap with the winding shaft may be fixed to the winding shaft, and the vicinity of the leading end portion in the conveying direction of the object may be fixed to the winding shaft by inserting the object into the gap. Further, in the above configuration, the gap may be formed so that the object can be wound around the winding shaft by 90 degrees or more.

[0010] Further, in the above configuration, the winding guide has a first plate-like portion, a second plate-like portion whose one end is connected at an angle of 90 degrees to one end of the first plate-like portion, a third plate-like portion whose one end is connected at an angle of 135 degrees to the other end of the second plate-like portion, and a fourth plate-like portion whose one end is connected at an angle of 135 degrees to the other end of the second plate-like portion. The first plate-like portion and the fourth plate-like portion face each other in the direction in which the second plate-like portion extends. The winding shaft has, in a side view, an arc-shaped portion and a straight line portion connecting both ends of the arc-shaped portion. The winding shaft may be integrated with the winding guide by fixing the straight line portion to the inner surface near the other end of the first plate-like portion.

[0011] In the above configuration, the winding of the object by the winding shaft may be stopped when the end portion in the direction opposite to the conveyance direction of the object is located near directly above the winding shaft.

[0012] In the above configuration, the conveyance path may have a feed roller that feeds the object in the conveyance direction, and the rotation speed of the feed roller may be lower than the rotation speed of the winding shaft. In the above configuration, the object may be a cushion body formed from a filament three-dimensional conjugate.

Mode for Carrying Out the Invention

[0015] Hereinafter, exemplary embodiments of the present invention will be described with reference to each drawing. In the drawings, the left - right direction is taken as the X - direction, with the left side being X1 and the right side being X2, the front - rear direction is taken as the Y - direction, with the front side being Y1 and the rear side being Y2, and the up - down direction is taken as the Z - direction, with the upper side being Z1 and the lower side being Z2. When the winding device is in use, the floor surface side on which the winding device is placed is the lower side (Z2 side).

[0016] <Overall Configuration of the Winding Device> FIG. 1 is a perspective view of the winding device 1 according to an exemplary embodiment of the present invention as viewed from the approximate right side, FIG. 2 is a perspective view of the winding device 1 as viewed from the approximate left side, and FIG. 3 is a perspective view of the winding device 1 as viewed from the approximate front side.

[0017] The winding device 1 is a device for winding a bedding as an example of a workpiece (object). In particular, here, the bedding is a cushion body used for a bed mattress or the like. More specifically, the cushion body is formed from a filament three - dimensional conjugate (three - dimensional network structure) obtained by three - dimensionally fusion - bonding filaments made of a thermoplastic resin, and has become a substantially plate - like body with flexibility. Since the filament three - dimensional conjugate is known as disclosed in, for example, Japanese Patent Application Laid - Open No. 2020 - 26586, its detailed description is omitted here.

[0018] The winding device 1 includes a conveying roller 2, a pair of feeding rollers 3, a left side plate 4, a right side plate 5, a pair of feeding workpiece 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, a discharge cylinder 12, a feeding roller drive mechanism 13, a winding shaft drive mechanism 14, a bag set jig 15, a winding shaft supporter 16, a lower frame 17, a pair of air cylinders 18, a discharge bar 19, and a winding workpiece sensor 20.

[0019] The plurality of conveying rollers 2, the pair of feeding rollers 3, and the movable conveying path 8 constitute a 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 FIGS. 1 and 2.

[0020] Each of the plurality of conveying rollers 2 is rotatable around a rotation axis extending in the left - right direction (axial direction), and is arranged side by side from the rear side to the front side. Each conveying roller 2 is arranged between the left side plate 4 and the right side plate 5.

[0021] Specifically, the pair of feeding rollers 3 consists of an upper feeding roller 3A and a lower feeding roller 3B. The lower feeding roller 3B is arranged adjacent to the front side of the most front - side conveying roller 2 among the plurality of conveying rollers 2 (FIG. 4 to be described later). The upper feeding roller 3A is arranged above the lower feeding roller 3B. A gap SS is provided between the upper feeding roller 3A and the lower feeding roller 3B for inserting the workpiece (FIG. 4). The pair of feeding rollers 3 is rotationally driven around a rotation axis extending in the axial direction by a feeding roller drive mechanism 13. The feeding roller drive mechanism 13 includes a feeding motor 131 provided on the right side surface of the device and a gear box 132 provided on the left side surface of the device. A clutch is provided between the feeding motor 131 and the feeding roller 3, and by disengaging this clutch, the idling of the feeding roller 3 to be described later becomes possible.

[0022] 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 the presence of a work at the conveyance start position, which is a position immediately in front of the pair of feed rollers 3. The pair of input guides 7 is composed of a left guide 7A and a right guide 7B. Each guide 7A, 7B is slidable on the conveyance roller 2 in opposite directions in the left-right direction. That is, each guide 7A, 7B can approach or separate from each other in the left-right direction, and its slide position can be adjusted according to the width of the work. The work is sandwiched and guided by the input guides 7 from the left and right and then conveyed.

[0023] The movable conveyance path 8 is arranged in front of the pair of feed rollers 3 and extends in the front-rear direction. The movable conveyance path 8 is rotatable around a rotation axis extending in the axial direction, which is located near the rear end portion (the end portion on the reverse side of the conveyance direction) of itself. The more detailed configuration of the movable conveyance path 8 will be described later.

[0024] The take-up shaft 9 is arranged above the conveyance path 8. The take-up shaft 9 is rotationally driven around a rotation axis extending in the axial direction by a take-up shaft drive mechanism 14. The take-up shaft drive mechanism 14 includes a take-up motor 141 provided on the right side surface of the device. The take-up shaft 9 is a member for taking up the work.

[0025] The take-up guide 10 is a plate-like member fixed to the peripheral surface of the take-up shaft 9 and bent in a shape when viewed from the left-right side surface (Fig. 4). The take-up guide 10 extends over the entire axial direction of the take-up shaft 9. The take-up guide 10 is a member for guiding the insertion of the leading end portion in the conveyance direction of the work and fixing the vicinity of the leading end portion in the conveyance direction to the take-up shaft 9.

[0026] The plurality of guide rollers 11 are each rotatable around a rotation axis extending in the axial direction and are arranged in an arc shape around the take-up shaft 9 and the take-up guide 10 when viewed from the left-right side surface (Fig. 4). The guide rollers 11 come into contact with the work and guide the work when the number of windings of the work increases when winding up the work.

[0027] The take-up work sensor 20 is a sensor for detecting that the leading end of the work being conveyed is located at a predetermined position inside the take-up guide 10 in the conveyance direction.

[0028] A pair of left and right air cylinders 18 are fixed to the lower frame 17. The air cylinder 18 is connected to the movable conveyance path 8. When the air cylinder 18 is driving, the movable conveyance path 8 can stand up above the horizontal position. When the driving of the air cylinder 18 stops, the movable conveyance path 8 stops at the horizontal position.

[0029] The take-up shaft supporter 16 supports the take-up shaft 9. As will be described later, when discharging the work wound by the take-up shaft 9 to the left, the take-up shaft supporter 16 is driven to move downward so as not to interfere with the discharge of the work.

[0030] The bag setting jig 15 is a jig for fixing the storage bag for storing the work to the winding device 1, and is provided on the left side surface of the device.

[0031] The discharge cylinder 12 can move the discharge bar 19 in the left-right direction (axial direction). By moving the discharge bar 19 to the left, the work wound by the take-up shaft 9 is discharged into the storage bag fixed to the bag setting jig 15.

[0032] Note that the lower frame 17 has casters 17A at the four corners of the lower end. Thereby, for example, the user can push and move the winding device 1.

[0033] <Configuration of the movable conveyance path> FIG. 4 is a cross-sectional side view of a main part showing the configuration around the movable conveyance path 8 in the winding device 1. As shown in FIG. 4, the movable conveyance path 8 has four movable rollers 81A and one fixed roller 81B.

[0034] As shown in FIG. 6 described later, the movable conveyance path 8 has a frame 82 extending in the front-rear direction. The movable roller 81A is disposed and held between the left and right sides by the frame 82. The movable rollers 81A are arranged in the front-rear direction.

[0035] As shown in FIG. 4, one conveyance roller 2 is disposed adjacent to the front of the lower feed roller 3B. And a fixed roller 81B is disposed adjacent to the front of the conveyance roller 2. Four movable rollers 81A are disposed in front of the fixed roller 81B.

[0036] 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. That is, the movable roller 81A is movable up and down.

[0037] As shown in FIG. 4, the winding shaft 9 is disposed above the vicinity of the front end portion of the movable conveyance path 8. Also, as shown in FIG. 4, an air cylinder 18 is connected to the lower front end portion of the frame 82.

[0038] <Configuration of winding guide> FIG. 5 is a side view of the winding guide 10 and the winding shaft 9 in a side view in the left-right direction. As shown in FIG. 5, the winding guide 10 is a plate-like member having a shape bent in a side view in the left-right direction, and integrally includes 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.

[0039] One end of the first plate-like portion 101 is connected to one end of the second plate-like portion 102, and the angle formed with the second plate-like portion 102 is 90 degrees. The other end of the second plate-like portion 102 is connected to one end of the third plate-like portion 103, and the angle formed with the third plate-like portion 103 is 135 degrees. The other end of the third plate-like portion 103 is connected to one end of the fourth plate-like portion 104, and the angle formed with the fourth plate-like portion 104 is 135 degrees. The first plate-like portion 101 and the fourth plate-like portion 104 face each other in the direction in which the second plate-like portion 102 extends.

[0040] The take-up shaft 9 has an arc-shaped portion 9A with a diameter D in a side view in the left-right direction, and a straight portion 9B connecting both ends of the arc-shaped portion 9A. By fixing the straight portion 9B to the inner surface near the other end of the first plate-shaped portion 101, the take-up shaft 9 is integrated with the take-up guide 10.

[0041] A gap S is formed between the take-up guide 10 and the take-up shaft 9. It is possible to insert a workpiece from the opening SA of the gap S into the gap S. As shown in FIG. 5, in a side view in the left-right direction, the gap S extends from the opening SA to a position deeper than the position of a line segment L2 obtained by rotating a line segment L1 connecting the rotation axis position (center position of the arc-shaped portion 9A) of the take-up shaft 9 and the outer end of the opening SA by 90 degrees around the rotation axis position. Thereby, it is possible to wind the workpiece around the take-up shaft 9 by 90 degrees or more around the rotation axis. Therefore, the workpiece can be firmly fixed to the take-up shaft 9. Note that the take-up guide 10 of the present embodiment extends over the entire axial direction of the take-up shaft 9, but other forms may be adopted as long as the workpiece can be appropriately fixed. For example, the take-up guide 10 may be in a claw shape (the same shape as in FIG. 5 in a side view in the left-right direction, but shortened in the axial direction of the take-up shaft 9), and may be provided only at both axial ends of the take-up shaft 9, for example.

[0042] <Configuration of the bag set jig> FIG. 6 is an enlarged view of a main part showing the configuration around the bag set jig 15 in the take-up device 1. The bag set jig 15 has a flange 151 and bag gripping portions 15A to 15C.

[0043] The flange 151 is attached to the outer surface of the left side plate 4. The opening 151A of the flange 151 is disposed on the left side of the take-up shaft 9 and faces the take-up shaft 9 in the left-right direction.

[0044] Near the outer peripheral end of the flange 151, the bag gripping portions 15A to 15C are arranged at equal intervals around the central axis extending in the left - right direction of the flange 151. The bag gripping portions 15A to 15C are each openable and closable by a hinge. When the bag gripping portions 15A to 15C are in the open state, there is a space for inserting the storage bag between the flange 151 and the bag gripping portions 15A to 15C (the bag gripping portions 15B and 15C in FIG. 6 are in the open state). When the bag gripping portions 15A to 15C are in the closed state, there is almost no gap between the flange 151 and the bag gripping portions 15A to 15C, and the storage bag can be gripped between the flange 151 and the bag gripping portions 15A to 15C (the bag gripping portion 15A in FIG. 6 is in the closed state).

[0045] Thus, by setting the bag gripping portions 15A to 15C in the open state, attaching the storage bag to the flange 151, and then setting the bag gripping portions 15A to 15C in the closed state, the storage bag can be fixed to the winding device 1.

[0046] <Configuration of the 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 viewed from the right side of the winding device 1. The discharge bar 19 that can move in the left - right direction by the discharge cylinder 12 (FIG. 8) is located at the initial position on the back side of the paper in FIG. 7 in the state shown in FIGS. 7 and 8. The discharge bar 19 is located on the right side (the back side of the paper in FIG. 7) of the work wound by the winding shaft 9 in the state of the initial position. The discharge bar 19 moves to the left side (the front side of the paper in FIG. 7) from the initial position, thereby pushing out the wound work toward the bag setting jig 15 side. As a result, the work is stored in the storage bag set on the bag setting jig 15.

[0047] <Processing steps of the winding device> Next, the processing steps performed by the winding device 1 according to the present 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 the present embodiment. As shown in FIG. 10, the winding device 1 has a control unit 30 that controls each part.

[0048] When the process of the flowchart shown in FIG. 9 starts, first in step S1, the control unit 30 determines whether or not a workpiece is detected by the feed work sensors 6A and 6B. While not detected (NO in step S1), step S1 is repeated.

[0049] Here, when an operator sets a substantially plate-shaped workpiece on the conveying roller 2, pushes the workpiece in the conveying direction toward the feed motor 3 side, and the leading end portion of the workpiece in the conveying direction reaches the conveying start position immediately in front of the feed roller 3, the workpiece is detected by the feed work sensors 6A and 6B (YES in step S1). Then, the process proceeds to step S2, and the control unit 30 determines whether or not a storage bag is set in the bag setting jig 15.

[0050] Whether or not a storage bag is set in the bag setting jig 15 can be confirmed, for example, by checking whether all of the bag gripping portions 15A to 15C are in a closed state. While the storage bag is not set (NO in step S2), the control unit 30 repeats step S2.

[0051] When it is determined by the control unit 30 that the storage bag is set (YES in step S2), the process proceeds to step S3, and the control unit 30 starts driving the air cylinder 18. As a result, as in step S4, the movable conveyance path 8 stands up from the horizontal posture. At this time, as shown in the schematic diagram of FIG. 11, the take-up guide 10 is in the posture of the initial position such that the opening SA is on the lower side. Then, the movable conveyance path 8 rotates around the rotation axis J1 of the fixed roller 81B until it contacts the fourth plate-shaped portion 104 of the take-up guide 10 and stands up from the horizontal posture (dashed line in FIG. 11). After standing up, until step S10 described later is performed, the movable conveyance path 8 is continuously urged upward by the action of the air cylinder 18 with a substantially constant force.

[0052] Thereafter, in step S5, the control unit 30 starts driving the feed motor 131 to start driving the feed rollers 3 (the upper feed roller 3A and the lower feed roller 3B). Then, the leading end portion of the workpiece in the conveying direction is drawn into the gap SS (FIG. 4) between the pair of feed rollers 3, and the conveying process of the workpiece in the conveying direction is started.

[0053] As a result, as shown in FIG. 11, the workpiece W is conveyed in the conveying direction A, and the leading end portion T1 of the workpiece W in the conveying direction passes over the rollers in the order of the fixed roller 81B of the movable conveying path 8 and the movable roller 81A from the conveying roller 2 shown in FIG. 11.

[0054] Then, the leading end portion T1 of the workpiece W in the conveying direction enters inside through the opening SA in the gap S between the winding guide 10 and the winding shaft 9. Then, as shown in FIG. 12, the leading end portion T1 of the workpiece W in the conveying direction reaches a predetermined position P that is further rotated from the line segment L1 (FIG. 10) described above by 90 degrees around the rotation axis J2 of the winding shaft 9. As a result, as shown in FIG. 12, winding of the workpiece W around the winding shaft 9 by 90 degrees or more near the leading end portion T1 in the conveying direction becomes possible. Note that the specific position of the predetermined position P can be arbitrarily set within a range where the leading end portion T1 of the workpiece W in the conveying direction does not accidentally deviate from the gap S.

[0055] After step S5, in step S6, the control unit 30 determines whether a workpiece is detected by the winding workpiece sensor 20. When the leading end portion T1 of the workpiece W in the conveying direction reaches the predetermined position P as shown in FIG. 12, the workpiece W is detected by the winding workpiece sensor 20. Note that the winding workpiece sensor 20 is shown in FIG. 8.

[0056]

[0055] If a workpiece is detected by the winding workpiece sensor 20 (YES in step S6), the process proceeds to step S7, and the control unit 30 stops the driving of the feed roller 3 by stopping the driving of the feed motor 131. As a result, the conveyance process of the workpiece is stopped.

[0057] Thereafter, the process proceeds to step S8, and the control unit 30 starts driving the take-up motor 141 and starts driving the take-up shaft 9. As a result, the take-up shaft 9 starts rotating around the rotation axis J2 in the clockwise direction when viewed from the left side. At this time, the control unit 30 idles the feed motor 131 (i.e., the feed roller 3). Note that the control unit 30 is not limited to this, and may control the rotation speed of the feed roller 3 to be lower than the rotation speed of the take-up shaft 9. Thereby, the workpiece can be conveyed while being pulled in the conveyance direction, and slackness or the like of the workpiece can be more sufficiently suppressed.

[0058] In step S8, as shown in FIG. 13, the workpiece W is wound around the take-up shaft 9 and the take-up guide 10. At this time, as shown in FIG. 13, as the winding of the workpiece W progresses, the radially dimension of the wound workpiece W gradually increases, and accordingly, it acts to press the movable conveyance path 8 downward against the biasing force of the air cylinder 18 described above. At this time, it can also be seen that the movable conveyance path 8 moves away from the take-up shaft 9 while being pressed (while applying a biasing force) toward the take-up shaft 9 side of the workpiece W by the air cylinder 18.

[0059] Therefore, the movable conveyance path 8 gradually descends while supporting the workpiece W with a substantially constant force. FIG. 13 shows that the movable conveyance path 8 has rotated and moved around the rotation axis J1 from the position (dashed line) of the movable conveyance path 8 in FIG. 12 to the position of the solid line. Thereby, since the workpiece W can be wound while being supported by the movable conveyance path 8, it is possible to continue winding while avoiding the situation where the workpiece W sags and the winding becomes unstable.

[0060] FIG. 14 shows a state where the winding further progresses from FIG. 13, and the movable conveyance path 8 has moved (descended) from the position (dashed line) in the state of FIG. 13 to the position of the solid line.

[0061] Then, in step S9, the control unit 30 stops driving the take-up motor 141, thereby stopping the drive of the take-up shaft 9. This stop timing is preferably, for example, the timing when the end portion T2 in the direction opposite to the conveyance direction of the workpiece W is positioned near directly above the take-up shaft 9, as shown in FIG. 15. If, in the take-up stop state, the take-up shaft 9 rotates further to the left than shown in FIG. 15, the vicinity of the end portion T2 will be peeled off from the workpiece W, making it difficult to store during the discharge process to the storage bag described later.

[0062] To set the take-up stop timing to the timing when the end portion T2 is positioned near directly above the take-up shaft 9, for example, the end portion T2 may be detected by a sensor (not shown). Alternatively, after the control unit 30 determines that the workpiece W is no longer detected by the feed workpiece sensors 6A and 6B, the time measurement may be started, and when a predetermined time has elapsed, the drive of the take-up shaft 9 may be stopped.

[0063] When the take-up process stops in step S9, in step S10, the control unit 30 stops driving the air cylinder 18, thereby lowering the movable conveyance path 8 to the horizontal posture. Then, proceeding to step S11, the control unit 30 drives the discharge cylinder 12 to move the discharge bar 19 from the initial position to the left. As a result, the workpiece is pushed out toward the bag setting jig 15 by the discharge bar 19, and the workpiece is stored in the storage bag. When discharging the workpiece by the discharge bar 19, the take-up shaft supporter 16 is driven to move downward in advance so as not to obstruct the discharge of the workpiece.

[0064] Then, it returns to step S1. In the subsequent step S2, when determining whether the storage bag is set, it is preferable to confirm that the bag gripping portions 15A to 15C of the bag setting jig 15 are once in the open state and then in the closed state. This is because if it is only determined whether it is in the closed state, there is a possibility that the previous storage bag instead of a new storage bag is set.

[0065] After step S11, if the operator sets a new storage bag and then sets a new workpiece W on the conveyance path 50 and pushes it toward the feed roller 3, the process proceeds to step S3 and the conveyance process is started.

[0066] As described above, according to the winding device 1 according to the present embodiment, it is possible to automatically perform the conveyance process, winding process, and discharge process of the workpiece. Therefore, a series of operations of winding up the workpiece to make it compact and storing it in a storage bag can be performed very efficiently, and even when there is a large amount of workpieces, the efficiency of the operation can be significantly improved.

[0067] <Others> As described above, the winding device 1 performs a conveyance process of placing the workpiece on the conveyance path 50 and conveying it toward the winding shaft 9, fixing the vicinity of the leading end in the conveyance direction of the workpiece to the winding shaft 9, and rotating the winding shaft 9 to wind up the workpiece. A part of the conveyance path 50 is formed as a movable conveyance path 8 that moves away from the winding shaft 9 after the conveyance process. Therefore, the conveyance path 50 is configured not to hinder the winding of the workpiece by moving away from the winding shaft 9 while facilitating the conveyance of the workpiece and the fixing to the winding shaft 9. In this way, the winding device 1 is devised to improve the efficiency of the winding operation.

[0068] As described above, the embodiments of the present invention have been described. However, the configuration of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the invention. That is, the above embodiments should be considered as illustrative in all respects and not restrictive. The technical scope of the present invention is shown not by the description of the above embodiments but by the scope of the claims, and it should be understood that all modifications belonging to the meaning and scope equivalent to the scope of the claims are included.

Industrial Applicability
