Description

[Technical Field]

[0001] The present invention relates to a hose winding device and method, and more particularly to a hose winding device and method that can easily change the winding diameter of the hose. [Background technology]

[0002] In manufacturing lines for hoses such as rubber hoses, the hoses are wound at a predetermined length onto drums for temporary storage or transportation (see, for example, Patent Document 1). There are various types of hose winding devices, and turret-type winding devices are used to make the hose winding process more efficient.

[0003] In a turret-type winding device, a drum body is rotatably supported on both ends of an arm around a rotation axis. Once the hose winding process onto the drum body at one end of the arm is completed, the arm is rotated around the pivot shaft to move the drum body from the winding position to the drum body removal position, and the empty drum body that was waiting at the removal position is moved to the winding position. At the winding position, the winding process is performed on the empty drum body. At the removal position, a bundling process is performed in which the hose wound onto the drum body is bundled with a bundling wire, and then a removal process is performed in which the wound hose bundled with the bundling wire is removed from the drum body. The hose removed from the drum body is transported to a storage facility or the like.

[0004] In this way, with a turret-type winding device, while the winding process is performed using one drum, the bundling and detaching processes are performed using the other drum. By performing different processes in parallel on each drum, there is an advantage in that a series of processes can be efficiently performed, from the start of winding the hose onto the drum to transporting the wound hose, bound with a bundling wire, to the subsequent process.

[0005] Since the hose is wound around the outer peripheral surface of a drum, the winding diameter of the hose is determined by the outer diameter of the drum used. While appropriate winding diameters exist depending on the hose specifications, conventional winding devices require a drum with the desired outer diameter to achieve the desired winding diameter. This requires the cumbersome task of attaching a drum corresponding to the desired winding diameter to the arm. If the drum were configured to be expandable and contractible to change the drum outer diameter in order to eliminate the need for drum replacement, the device structure would become more complex and require significant costs. Therefore, there is room for improvement in how to easily change the hose winding diameter. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 60-120040 Summary of the Invention [Problem to be solved by the invention]

[0007] An object of the present invention is to provide a hose winding device and method that can easily change the winding diameter of the hose. [Means for solving the problem]

[0008] In order to achieve the above object, the hose reeling device of the present invention has an arm pivotally supported around a pivot shaft, a rotation drive motor for rotating the arm around the pivot shaft, and drum bodies pivotally supported around rotation shafts at both longitudinal ends of the arm, and by rotating the arm, each drum body is moved between a winding position and a removal position, and at the winding position, a winding step is performed in which a predetermined length of hose is wound onto the empty drum body, and at the removal position, a hose is wound onto the drum body. bodyThe turret-type hose winding device performs a binding process in which the hose wound around the drum is bound with a binding wire, and a removal process in which the hose bound with the binding wire in a wound state is removed from the drum body, and is characterized in that it is provided with a cylindrical large-diameter attachment that is detachably attached to the outer periphery of each of the drum bodies.

[0009] In the hose winding method of the present invention, drum bodies are rotatably supported by a rotary shaft at both longitudinal ends of an arm that is pivotally supported around a rotary shaft, and the arm is pivoted to move each of the drum bodies between a winding position and a removal position, and a winding step is performed in which a predetermined length of hose is wound onto the empty drum body at the winding position, and a predetermined length of hose is wound onto the drum body at the removal position. body In a hose winding method using a turret-type hose winding device, the method includes a binding step in which the hose wound around the drum body is bound with a binding wire, and a removal step in which the hose bound with the binding wire in a wound state is removed from the drum body, and the method is characterized in that the outer diameter of at least one of the drum bodies is changed by attaching a cylindrical large-diameter attachment that is detachably attached to the outer periphery of at least one of the drum bodies. [Effects of the Invention]

[0010] According to the present invention, the drum body with the large-diameter attachment attached to its outer periphery is integrated with the large-diameter attachment, and its outer diameter becomes the same as that of the large-diameter attachment, allowing the hose winding diameter to be increased. In this way, by attaching and detaching the large-diameter attachment to the drum body, the winding diameter of the hose wound onto the drum body can be easily changed.

[0012] Hereinafter, a hose reeling device and method according to the present invention will be described based on an embodiment shown in the drawings.

[0013] The embodiment of the hose reeling device 1 illustrated in Figures 1 to 3 is a turret type and includes an arm 2 journaled on a revolving shaft 2a, a revolving drive motor 3 for revolving the arm 2, drum bodies 4A and 4B journaled rotatably on rotation shafts 5a and 5b at both longitudinal ends of the arm 2, and a control unit 9. The reeling device 1 further includes a cylindrical large-diameter attachment 10. The large-diameter attachment 10 is detachably attached to the outer periphery of the drum bodies 4A and 4B. Details of the large-diameter attachment 10 will be described later. In the production line for hose H, a hose supply unit 13 is located upstream of the reeling device 1, and a bundling machine 14 is located downstream.

[0014] The position of the drum body 4A arranged on the hose supply unit 13 side in Fig. 1 is the winding position P1, which will be described later. The position of the drum body 4B arranged on the binding machine 14 side is the removal position P2, which will be described later.

[0015] In this reeling device 1, the arm 2 is rotated vertically to move each of the drum bodies 4A, 4B between a reeling position P1 and a removal position P2. At the reeling position P1, a reeling process is carried out in which a predetermined length of hose is reeled onto the empty drum body 4A. At the removal position P2, a bundling process is carried out in which the hose H reeled onto the drum 4B is bound with a binding wire 15, and a removal process is carried out in which the hose H, bound with the binding wire 15 in a wound state, is removed from the drum body 4B.

[0016] The hose H wound up by the winding device 1 is of various types, such as a rubber hose or a resin hose. For example, a hose H in which a reinforcing layer formed by spirally winding a metal or resin reinforcing cord or a reinforcing layer formed by braiding such a reinforcing cord is embedded can be wound up by the winding device 1. The outer diameter of the hose H is, for example, about 10 mm to 40 mm.

[0017] The arm 2 is connected to a pivot 2a and pivots vertically around the pivot 2a. Various motors, such as a servo motor, can be used as the pivot drive motor 3 that rotates the pivot 2a. In this embodiment, the pivot drive motor 3 is attached to a support post that stands on the base.

[0018] The drums 4A and 4B are rotated around their respective rotation shafts 5a and 5b by respective rotation drive motors 6a and 6b, which are servo motors.

[0019] Each drum body 4A, 4B has a plurality of segments 4s connected to a base 4c that rotates together with the rotation shafts 5a, 5b, and a plurality of flanges 4f. Since each drum body 4A, 4B has a similar structure, the following description will focus on the drum body 4A.

[0020] As shown in Figures 4 and 5, the drum body 4A is made up of four segments 4s, each of which is formed by dividing a cylindrical body into equal parts in the circumferential direction. A gap extending in the axial direction of the drum is formed between adjacent segments 4s in the circumferential direction. The number of segments 4s is, for example, three to four. The outer peripheral surface of each segment 4s forms the outer peripheral surface of the drum around which the hose H is wound. The outer diameter of the outer peripheral surface of the drum is, for example, 30 cm to 60 cm.

[0021] Flanges 4f are provided at both ends of the drum body 4A in the axial direction. More specifically, flanges 4f are provided at both ends of each segment 4s in the axial direction. In this embodiment, a substantially rectangular plate-shaped flange 4f is provided at both ends of each of the four segments 4s in the axial direction.

[0022] The drum body 4A is supported by a cantilever on a rotating shaft 5a, and the rotating shaft 5a is connected to one side of the drum body 4A in the drum axis direction (the side where the rotation drive motor 6a is located). Therefore, the other side of the drum body 4A in the drum axis direction is a free end. Each flange portion 4f located on one side of the drum body 4A in the drum axis direction extends radially outward. Each flange portion 4f is composed of two plates, one of which can slide relative to the other in the drum radial direction. This allows the radial length of each flange portion 4f to be variable, and each flange portion 4f is designed to always protrude radially outward beyond the outer circumferential surface of the drum body 4A (segments 4s).

[0023] Each flange 4f located on the other axial end (free end) of the drum body 4A can be switched between extending radially outward and extending axially. The flanges 4f extending radially outward protrude radially outward beyond the outer circumferential surface of the drum body 4A (segments 4s), whereas the flanges 4f extending axially do not protrude radially outward beyond the outer circumferential surface of the drum body 4A (segments 4s). For example, the advancement and retreat of a fluid cylinder located in the inner space surrounded by each segment 4s and a link mechanism connected to this fluid cylinder allow each flange 4f to be switched between protruding radially outward beyond the outer circumferential surface of the drum body 4A (segments 4s) and not protruding.

[0024] The drum body 4A is also provided with a hose start end holder 7 that moves toward and away from the outer circumferential surface of the drum body 4A (segment 4s). When the hose start end holder 7, which is operated by a fluid cylinder or the like, moves toward the outer circumferential surface of the drum body 4A (segment 4s), it holds the start end Ht of the hose H by sandwiching it between itself and the outer circumferential surface of the drum body 4A (segment 4s).

[0025] In this embodiment, the rewinding device 1 further includes a hose detection sensor 8 disposed on the inner periphery of the drum body 4A and a passage 4t that connects the drum body 4A (segments 4s) in the drum radial direction. The hose detection sensor 8 can be any of a variety of known non-contact sensors that emit detection light and receive the detection light reflected by an object. The passage 4t is a notch or a through hole. In this embodiment, the passage 4t is an elongated notch extending in the drum axial direction.

[0026] A detection light is emitted from the hose detection sensor 8 toward the outside in the drum radial direction. If the hose H extends on the outer peripheral surface of the drum body 4A, crossing the passage portion 4t, the detection light that passes through the passage portion 4t is reflected by the hose H, passes through the passage portion 4t again, and is received by the hose detection sensor 8. In this way, the hose detection sensor 8 is configured to detect whether or not the hose H is wrapped around the drum body 4A.

[0027] A detection signal from the hose detection sensor 8 is input to the control unit 9. The control unit 9 operates the hose beginning end holding unit 7 based on this detection signal.

[0028] In this embodiment, the cables that supply electricity for operating the rotation drive motors 6a, 6b, flange portion 4f, and hose beginning end holder 7 are held by a wire protection moving guide 9a such as a Cableveyor (registered trademark), as shown in Figure 1. As the arm 2 rotates, the cables held by the wire protection moving guide 9a move a predetermined length of stroke together with the wire protection moving guide 9a. The wire protection moving guide 9a moves a stroke in the up and down direction in Figure 1.

[0029] The control unit 9 controls the movement of the swivel drive motor 3, the rotary drive motors 6a and 6b, and the hose start end holder 7, as well as the movement of the flange 4f to switch between a state in which it protrudes outward from the outer circumferential surface of the drum body 4A and a state in which it does not protrude. A known computer is used as the control unit 9.

[0030] The hose supply unit 13 has a conveying mechanism 13a and a cutter 13b. A known belt conveyor or similar device is used as the conveying mechanism 13a. The manufactured hose H is placed on the conveying mechanism 13a and moved to be supplied to the winding device 1. The supplied hose H is cut to a predetermined length by the cutter 13b.

[0031] The bundling machine 14 bundles the hose H, which has been wound around the drum bodies 4A, 4B by the winding device 1, with a bundling wire 15 while it is wound up. Various known types of bundling machines can be used as the bundling machine 14. The bundling wire 15, guided out by bundling guides 14a, 14b of the bundling machine 14, bundles the hose H at the position of the gap that is formed between circumferentially adjacent segments 4s and extends in the axial direction of the drum.

[0032] An example of the procedure for winding up the hose H using this winding device 1 will now be described.

[0033] 1 and 2, at the winding position P1, a winding process is carried out in which a predetermined length of hose H is wound onto an empty drum body 4A, and at the removing position P2, a bundling process is carried out in which the hose H wound onto the drum 4B is bound with a binding wire 15, and a removing process is carried out in which the hose H wound and bound with the binding wire 15 is removed from the drum body 4B. The winding process, the bundling process, and the removing process are carried out in parallel.

[0034] In the winding process, the start end Ht of the hose H supplied from the hose supply unit 13 is inserted between the outer circumferential surface of the drum body 4A and the hose start end holder 7. When the start end Ht of this hose H extends across the passing portion 4t on the outer circumferential surface of the drum body 4A (segment 4s), it is detected by the hose detection sensor 8, and a detection signal is input to the control unit 9.

[0035] When the control unit 9 receives this detection signal and determines that the hose H is wound around the drum body 4A, it moves the hose starting end holding part 7 from the state in Figure 5 toward the outer circumferential surface of the drum body 4A as shown in Figure 6. As a result, the starting end Ht is sandwiched and held between the hose starting end holding part 7 and the outer circumferential surface of the drum body 4A. During the winding process, the flanges 4f at both ends of the drum body 4A in the axial direction protrude outward from the outer circumferential surface of the drum.

[0036] Next, the rotary drive motor 6a is operated to rotate the drum body 4A about the rotary shaft 5a as shown in Fig. 3, thereby winding the hose H onto the drum body 4A. The hose H is cut to a predetermined length by the cutter 13b at an appropriate timing, and is wound spirally onto the outer circumferential surface of the drum body 4A between the flanges 4f that are spaced apart in the axial direction of the drum body 4A.

[0037] In the bundling process, the bundling wire 15 led out from the bundling guides 14a, 14b is repeatedly wound across the hose H wound around the drum body 4B in the gaps extending in the drum axial direction, which are formed between circumferentially adjacent segments 4s of the drum body 4B. As a result, the hose H wound in a spiral shape around the drum body 4B is bundled with the bundling wire 15. The drum body 4B is sequentially rotated 90° around the rotation shaft 5b, and the hose H is similarly bundled with the bundling wire 15 at all locations (four locations in this embodiment) in the gaps between circumferentially adjacent segments 4s.

[0038] During the bundling process, the flanges 4f at both ends of the drum body 4B in the axial direction protrude outward from the outer circumferential surface of the drum. At an appropriate timing, the hose starting end holder 7 is moved away from the outer circumferential surface of the drum body 4B to release the hold of the hose starting end Ht by the hose starting end holder 7.

[0039] In the removal process after the bundling process is completed, the flange 4f at the free end of the drum body 4B in the axial direction is switched from extending radially outward to extending axially, as shown in Figures 7 and 8. This causes the flange 4f to no longer protrude outward from the outer circumferential surface of the drum.

[0040] Next, the hose H, which is wound in a spiral shape around the drum body 4B and bound with the binding wire 15, is moved toward the free end of the drum body 4B in the drum axial direction using a known transfer device and removed from the drum body 4B. The hose H removed from the drum body 4B is then transferred to a storage facility or the like using this transfer device.

[0041] After the winding and removal steps are completed, the arm 2 is rotated counterclockwise by 180° around the pivot 2a as shown in Fig. 9. As a result, the drum 4A with the hose H wound thereon is moved from the winding position P1 to the removal position P2, and the empty drum 4B is moved from the removal position P2 to the winding position P1 as shown in Fig. 10.

[0042] When the arm 2 is rotated, the control unit 9 controls the rotation drive motor 3 and the rotation drive motor 6a in cooperation with each other while the drum body 4A is being moved from the winding position P1 to the detaching position P2 so that the wound-up hose H does not become unwound (does not come unwound), as shown in Fig. 9. The control unit 9 controls the rotation drive motor 6a so as to eliminate relative rotation of the drum body 4A, which is being moved from the winding position P1 to the detaching position P2, around the rotation shaft 5a.

[0043] Specifically, as illustrated in Figures 9 and 10, the rotary drive motor 6a is controlled to rotate the drum body 4A around the rotary shaft 5a so that the end portion He of the hose H, which was located diagonally below and to the right of the outer peripheral surface of the drum body 4A at the winding position P1, is always located diagonally below and to the right of the outer peripheral surface of the drum body 4A while the drum body 4A moves from the winding position P1 to the removal position P2.

[0044] In this way, the drum body 4A pivots from the winding position P1 to the removal position P2 while the end portion He is maintained in a position diagonally downward to the right on the outer peripheral surface of the drum body 4A where unwinding (unwinding) is unlikely to occur. Note that the position where the end portion He is maintained as the drum body 4A pivots from the winding position P1 to the removal position P2 is not limited to the diagonally downward to the right on the outer peripheral surface of the drum body 4A, as long as it is a position where unwinding (unwinding) of the hose H is unlikely to occur. For example, the end portion He may be maintained in a position diagonally downward to the left on the outer peripheral surface of the drum body 4A or at the bottom end of the outer peripheral surface.

[0045] The drum 4A, which has moved from the winding position P1 to the removal position P2, is subjected to the binding and removal processes that were previously performed on the drum 4B. The drum 4B, which has moved from the removal position P2 to the winding position P1, is subjected to the winding process that was previously performed on the drum 4A. After the winding and removal processes are completed, the arm 2 is rotated clockwise around the pivot 2a to move the drum 4B from the winding position P1 to the removal position P2, and move the drum 4A from the removal position P2 to the winding position P1.

[0046] While the empty drum body 4B is being moved from the removal position P2 to the winding position P1, the control unit 9 can control the rotation drive motor 3 and the rotation drive motor 6b in conjunction with each other to position the hose beginning end holder 7 of the drum body 4B at a predetermined hose holding position. When the empty drum body 4B is placed at the winding position P1, the position at which the hose beginning end holder 7 can easily hold the beginning end Ht of the hose H supplied from the hose supply unit 13 is set as this predetermined hose holding position.

[0047] By positioning the hose start end holding part 7 in this way, when the empty drum body 4B moves to the winding position P1, the start end Ht of the hose H supplied from the hose supply part 13 can be quickly held by the hose start end holding part 7. This allows the winding process to start immediately, which is even more advantageous for efficiently winding the hose H onto the drum body 4B.

[0048] In this embodiment, the arm 2 is alternately rotated 180° clockwise and 180° counterclockwise about the pivot shaft 2a, thereby moving the drum bodies 4A, 4B between the winding position P1 and the detaching position P2. This eliminates the need to connect the cables that supply electricity to the rotation drive motors 6a, 6b, flange portion 4f, and hose beginning end holder 7 to the respective devices via slip rings. Therefore, in this embodiment, these cables are held by the wire protection movement guide 9a.

[0049] The arm 2 can also be designed to rotate 360° about the pivot 2a to move each of the drum bodies 4A, 4B between the winding position P1 and the removal position P2. That is, the arm 2 can be designed to rotate in only one direction, either clockwise or counterclockwise, about the pivot 2a. In this case, the cables that supply electricity to operate the rotation drive motors 6a, 6b, flange 4f, and hose start end holder 7 are connected to the respective devices via slip rings.

[0050] When the winding diameter of the hose H is to be increased, a detachable large-diameter attachment 10 is attached to the outer periphery of the drum body 4A as shown in Fig. 11. 4 A is integrated with the large diameter attachment 10 attached.

[0051] Similarly, the large-diameter attachment 10 can be attached to the drum body 4B. The large-diameter attachment 10 is detachably attached to the outer periphery of at least one of the drum bodies 4A, 4B. The procedure is the same whether the large-diameter attachment 10 is attached to or detached from the outer periphery of the drum body 4A or the outer periphery of the drum body 4B, so the following description will focus on the case where the large-diameter attachment 10 is attached to or detached from the outer periphery of the drum body 4A.

[0052] Describing the large-diameter attachment 10 in detail, as illustrated in Figures 11 to 13, the large-diameter attachment 10 has a plurality of segments 11. The number of segments 11 constituting one large-diameter attachment 10 is the same as the number of segments 4s of the drum body 4A, for example, three or four. Each segment 11 has a shape obtained by dividing a cylinder into equal parts in the circumferential direction. A gap extending in the axial direction of the drum is formed between adjacent segments 11 in the circumferential direction.

[0053] When the large-diameter attachment 10 is attached to the outer periphery of the drum body 4A, a corresponding segment 11 is disposed on the outer periphery of each segment 4s. The gaps between adjacent segments 4s and the gaps between adjacent segments 11 corresponding to these segments 4s are aligned along the drum circumferential direction. When the attachment 10 is attached to the outer periphery of the drum body 4A and integrated with the drum body 4A, the outer periphery of each segment 11 becomes the outer periphery of the drum around which the hose H is wound.

[0054] A spacer portion 12 protrudes from the inner peripheral surface of each segment 11. The spacer portion 12 is interposed between the inner peripheral surface of each segment 11 and the outer peripheral surface of the corresponding segment 4s. By varying the length of these spacer portions 12 in the drum radial direction, the outer diameter of the large-diameter attachment 10 can be varied.

[0055] The large-diameter attachment 10 (segment 11) is formed with an attachment passage 11t that communicates in the drum radial direction. The attachment passage 11t is a notch or a through-hole. In this embodiment, the attachment passage 11t is an elongated notch extending in the drum axial direction.

[0056] Each segment 11 is integrated with a corresponding segment 4s located on the inner periphery side by a connecting member such as a bolt. In this embodiment, the segment 11 and the segment 4s are connected and integrated by a bolt that connects the segment 11 and the spacer portion 12 and is screwed onto the segment 4s.

[0057] When the large-diameter attachment 10 is mounted on the outer periphery of the drum body 4A, it is positioned so that the passing portion 4t and the attachment passing portion 11t communicate in the radial direction. That is, the segment 11 on which the attachment passing portion 11t is formed is mounted to the segment 4s on which the passing portion 4t is formed so that the positions of the passing portion 4t and the attachment passing portion 11t in the drum circumferential direction are aligned. A hose detection sensor 8 is disposed on the inner periphery of the segment 4s on which the passing portion 4t is formed.

[0058] Even when a large diameter attachment 10 is attached to the outer periphery of the drum body 4A, the hose detection sensor 8 emits detection light radially outward from the drum, as shown in Fig. 13. When a hose H extends on the outer periphery of the large diameter attachment 10 (segment 11), crossing the attachment passing section 11t, the detection light that passes through the passing section 4t and the attachment passing section 11t is reflected by the hose H, passes through the attachment passing section 11t and the passing section 4t again, and is received by the hose detection sensor 8. In this way, the hose detection sensor 8 is configured to detect whether or not the hose H is wound around the large diameter attachment 10 (segment 11).

[0059] In the winding process, the starting end Ht of the hose H supplied from the hose supply unit 13 is inserted between the outer peripheral surface of the large diameter attachment 10 (segment 11) and the hose starting end holding unit 7. When the starting end Ht of this hose H extends across the outer peripheral surface of the large diameter attachment 10 (segment 11) and crosses the attachment passing portion 11t, it is detected by the hose detection sensor 8, and this detection signal is input to the control unit 9.

[0060] When the control unit 9 receives this detection signal and determines that the hose H is wound around the drum body 4A integrated with the large diameter attachment 10, it moves the hose start end holding unit 7 from the state shown in Figure 13 to approach the outer circumferential surface of the large diameter attachment 10 (segment 11) as shown in Figure 14. As a result, the start end Ht is sandwiched and held between the hose start end holding unit 7 and the outer circumferential surface of the large diameter attachment 10 (segment 11).

[0061] During the winding process, the flanges 4f at both ends of the drum body 4A in the axial direction protrude outward from the outer circumferential surface of the large-diameter attachment 10. In this embodiment, in each of the flanges 4f located on one side of the drum body 4A in the axial direction, one plate slides outward in the radial direction of the drum relative to the other plate. This allows these flanges 4f to protrude outward from the outer circumferential surface of the large-diameter attachment 10 (segments 11).

[0062] Even when the large diameter attachment 10 is attached to the outer periphery of the drum body 4A, the winding process, bundling process, and removal process are performed in the same manner as when the large diameter attachment 10 is not attached. To reduce the winding diameter of the hose H, the attached large diameter attachment 10 (each segment 11) can be removed from the drum body 4A.

[0063] In this way, the drum body 4A with the large diameter attachment 10 attached to its outer periphery is integrated with the large diameter attachment 10, and its outer diameter becomes the same as that of the large diameter attachment 10, making it possible to increase the winding diameter of the hose H. Therefore, by attaching or detaching the large diameter attachment 10 to or from the drum body 4A, the winding diameter of the hose H wound around the drum body 4A can be easily changed.

[0064] In this embodiment, the hose detection sensor 8 is disposed on the inner circumferential side of the segment 4s of the drum bodies 4A, 4B, and a passage 4t is formed in the segment 4s, and an attachment passage 11t is formed in the segment 11. This makes it possible to determine whether or not the hose H is wound around the drum bodies 4A, 4B (the large-diameter attachment 10 attached to the drum bodies 4A, 4B), regardless of whether or not the large-diameter attachment 10 is attached to the drum bodies 4A, 4B.

[0065] In this embodiment, the passage 4t and the attachment passage 11t extend in the drum axial direction. Therefore, even if the segments 4s and 11 are slightly misaligned in the drum axial direction as a result of switching the flanges 4f arranged on the free end of the drum width direction between extending radially outward and extending in the drum axial direction, the detection light of the hose detection sensor 8 can easily pass through the passage 4t and the attachment passage 11t.

[0066] The application of the present invention is not limited to the case where the rotation direction of the arm 2 is vertical. For example, the present invention can also be applied to a winding device 1 in which the rotation shaft 2a extends vertically and the arm 2 rotates horizontally. [Explanation of symbols]
