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 is equipped with a fluid cylinder that opens and closes a flange portion in an internal space, and that allows the diameter of a drum body in which the hose winding process, tying process with a binding wire, and hose removal process are carried out to be easily reduced, thereby making it possible to further reduce 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] The drum body has flanges at both ends in the axial direction of the drum in order to wind the hose into a spiral shape of a predetermined height. The flange, located on one side of the drum width direction, can be switched between a state in which it protrudes from the outer surface of the drum body (a radially open state) and a state in which it does not protrude from the outer surface (a closed state) in order to remove the wound hose from the drum body. For this reason, a fluid cylinder is located in the internal space of the drum body to switch the flange between the open and closed states. The flange can be switched between the open and closed states by moving the rod of this fluid cylinder back and forth via a link mechanism.

[0005] During the bundling process, a bundling guide of the bundling machine is inserted between adjacent circumferential segments that make up the drum body, and the bundling guide enters the internal space of the drum body. Therefore, the fluid cylinders must be spaced apart within the internal space of the drum, making it difficult to reduce the diameter of the drum body. Therefore, there is room for improvement in how to easily reduce the diameter of the drum body and further reduce the winding diameter of the hose. [Prior art documents] [Patent documents]

In this device, each drum body has a base portion disposed on the other end side in the drum width direction, and a tip end portion of a rod of each of the fluid cylinders is connected to the base portion, and each of the fluid Cylinder The base end of the cylinder body is connected to the corresponding flange portion via a link mechanism, and in the binding process, by extending each of the rods, each of the flange portions is brought into the open state, and a binding guide of the binding machine is inserted into the gap in the drum circumferential direction between the rods that are being extended.

[0009] In a hose winding method of the present invention, a drum body is rotatably supported by a rotating shaft at both longitudinal ends of an arm that is pivotally supported around a pivot shaft, and each of the drum bodies has a plurality of segments that are arranged at intervals around the drum circumference, a plurality of fluid cylinders that are arranged in an inner space surrounded by each of the segments, and a flange portion that is arranged on one end of each of the segments in the drum axial direction, and each of the flange portions is switched between an open state and a closed state radially around the drum axis by the corresponding fluid cylinder, and the arm is rotated to move each of the drum bodies between a winding position and a detaching position, and a winding step is performed in which a predetermined length of hose is wound around the empty drum body at the winding position, and a retraction step is performed in which the drum body is retracted at the detaching position. body In a hose winding method using a turret-type hose winding device, the method includes a bundling step in which the hose wound around the drum is bound with a binding wire, and a removing step in which the hose bound with the binding wire in a wound state is removed from the drum body.

[Effects of the Invention]

[0010] According to the present invention, in the bundling process, the rods of each of the fluid cylinders are extended to open the flanges, and a bundling guide of a bundling machine is inserted into the gap between the extended rods in the drum circumferential direction. In each of the fluid cylinders, the rod has a smaller diameter than the cylinder body. In the bundling process, the bundling guide is inserted into the gap between the rods in the drum circumferential direction, rather than the gap between the cylinder bodies in the drum circumferential direction, ensuring a larger gap for inserting the bundling guide. This advantageously allows the fluid cylinders to be positioned closer to each other, making it possible to easily reduce the diameter of the drum body and thereby reduce the hose winding diameter.

DETAILED DESCRIPTION OF THE INVENTION

[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] 1 to 4 is a turret type embodiment of a hose reeling device 1, 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 rotating shafts 8a and 8b at both longitudinal ends of the arm 2, and a control unit 11. In the production line for hose H, a hose supply unit 12 is disposed upstream of the reeling device 1, and a bundling machine 13 is disposed downstream.

[0014] The position of the drum body 4A arranged on the hose supply unit 12 side in Fig. 1 is a winding position P1, which will be described later. The position of the drum body 4B arranged on the binding machine 13 side is a 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 14, and a removal process is carried out in which the hose H, bound with the binding wire 14 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 8a and 8b by respective rotation drive motors 9a and 9b, 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 rotary shafts 8a, 8b, 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] The drum body 4A has multiple segments 4s, multiple fluid cylinders 5 arranged in the inner space surrounded by each of the segments 4s, and flange portions 4f arranged on both ends of each segment 4s in the drum axial direction. In this embodiment, the drum body 4A is made up of four segments 4s, but the number of segments 4s may be, for example, three to four.

[0021] Each segment 4s has a shape obtained by dividing a cylinder into equal parts in the circumferential direction. A gap extending in the drum axial direction is formed between adjacent segments 4s in the circumferential direction. The outer circumferential surface of each segment 4s becomes the outer circumferential surface of the drum around which the hose H is wound. The outer diameter of the outer circumferential surface of the drum is, for example, 30 cm to 60 cm.

[0022] Four fluid cylinders 5 extending in the drum axial direction are arranged in the inner cylindrical space surrounded by each segment 4s. The number of fluid cylinders 5 is the same as the number of segments 4s. Well-known air cylinders, hydraulic cylinders, etc. can be used as the fluid cylinders 5. Each fluid cylinder 5 extends and retracts a rod 7 relative to a cylinder body 6.

[0023] The tip end 7a of the rod 7 of each fluid cylinder 5 is connected to the base 4c. Cylinder The base end 6a of the cylinder body 6 of 5 is connected to the corresponding flange portion 4f via a link mechanism. This link mechanism can be any of various known link mechanisms that convert linear motion into rotational motion.

[0024] The flange portions 4f are disposed at both ends of each segment 4s in the axial direction of the drum. In this embodiment, the flange portions 4f are substantially rectangular plate-shaped and disposed at both ends of each segment 4s in the axial direction of the drum.

[0025] The drum body 4A is supported by a cantilever on a rotating shaft 8a, with one end of the drum body 4A in the drum axial direction being a free end. The rotating shaft 8a is connected to the other end of the drum body 4A in the drum axial direction (the side where the rotation drive motor 9a is located). Each flange 4f located at the other end of the drum body 4A in the drum axial direction extends radially outward and is designed to always protrude radially outward beyond the outer circumferential surface of the drum body 4A (segments 4s).

[0026] Each flange 4f located at one end (free end) of the drum body 4A in the axial direction is connected via a link mechanism to a base end 6a of a cylinder body 6 of a corresponding fluid cylinder 5. Each flange 4f located at one end of the drum in the axial direction is configured to be switched between an open state and a closed state radially around the drum axis by the corresponding fluid cylinder 5 connected thereto.

[0027] The flange portions 4f illustrated in Figures 3 and 4 are in a state where they open radially around the drum axis (rotation shaft 8a) and extend radially outward from the drum. In this open state, each flange portion 4f protrudes radially outward from the outer peripheral surface of the drum (the outer peripheral surface of the corresponding segment 4s). In a closed state, each flange portion 4f extends in the drum axial direction. In the closed state, each flange portion 4f does not protrude radially outward from the outer peripheral surface of the drum body 4A (segment 4s).

[0028] Each flange 4f located at one end (free end) of the drum in the axial direction switches between an open state and a closed state depending on the advancement and retreat (extension and contraction) of the rod 7 of each fluid cylinder 5. As shown in Fig. 4, the rotational position (rotational angle) of the drum body 4A about the rotation axis 8a when the drum circumferential gap L between the rods 7 of the fluid cylinders 5 arranged adjacent to each other in the circumferential direction of the drum is maximized is known in advance and stored in the control unit 11.

[0029] Furthermore, the drum body 4A is equipped with a hose start end holder 10 that moves toward and away from the outer circumferential surface of the drum body 4A (segment 4s). When the hose start end holder 10, which is operated by various fluid cylinders 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).

[0030] The control unit 11 controls the movements of the swivel drive motor 3, the rotary drive motors 9a and 9b, the hose start end holder 10, and each of the fluid cylinders 5. Therefore, the movement of switching the flange portion 4f between the open state and the closed state is controlled by the control unit 11. A known computer is used as the control unit 11.

[0031] The hose supply unit 12 has a conveying mechanism 12a and a cutter 12b. A known belt conveyor or similar device is used as the conveying mechanism 12a. The manufactured hose H is placed on the conveying mechanism 12a and moved to be supplied to the winding device 1. The supplied hose H is cut to a predetermined length by the cutter 12b.

[0032] The bundling machine 13 bundles the hose H, which has been wound around the drum bodies 4A, 4B by the winding device 1, with a bundling wire 14 while it is wound up. Various known types of bundling machines can be used as the bundling machine 13. The bundling wire 14, guided by bundling guides 13a, 13b of the bundling machine 13, bundles the hose H at the position of the gap that is formed between circumferentially adjacent segments 4s and extends in the drum axial direction.

[0033] An example of the procedure for winding up the hose H using this winding device 1 will now be described.

[0034] 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 14, and a removing process is carried out in which the hose H wound and bound with the binding wire 14 is removed from the drum body 4B. The winding process, the bundling process, and the removing process are carried out in parallel.

[0035] During the winding process, the starting end Ht of the hose H supplied from the hose supply unit 12 is inserted between the outer circumferential surface of the drum body 4A and the hose starting end holder 10, and the hose starting end holder 10 moves toward the outer circumferential surface of the drum body 4A. As a result, the starting end Ht is sandwiched and held between the hose starting end holder 10 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 9a is operated to rotate the drum body 4A about the rotary shaft 8a as shown in Figures 3 and 4, thereby winding the hose H onto the drum body 4A. The hose H is cut to a predetermined length by the cutter 12b 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 14 led out from bundling guides 13a and 13b is repeatedly wound across the hose H wound around the drum body 4B in the gaps extending in the drum axial direction that 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 14. The drum body 4B is sequentially rotated 90° around the rotation shaft 8b, and the hose H is similarly bundled with the bundling wire 14 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 10 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 10.

[0039] More specifically, as illustrated in Figures 5 and 6, during the bundling process, each rod 7 is extended, causing the flange portions 4f at one axial end (free end) of the drum to open radially around the drum axis. Therefore, each rod 7 is extended, and each cylinder body 6 moves away from the base 4c. From above the drum body 4B, one bundling guide 13b moves downward and enters the interior of the drum body 4B. That is, one bundling guide 13b enters from above into the circumferential gap (distance L in plan view) between the two upper rods 7 that are being extended.

[0040] The other bundling guide 13a moves horizontally from one end (free end) in the drum axial direction and enters the interior of the drum body 4B. That is, the other bundling guide 13a moves toward the drum axial center and enters the interior of the drum body 4B, bringing the bundling guides 13a and 13b into close proximity. In this state, the bundling wire 14 is led out between the bundling guides 13a and 13b, and the hose H is bundled.

[0041] In the removal process after the binding process is completed, the flange 4f at the free end in the axial direction of the drum body 4B is switched from an open state to a closed state 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.

[0042] Next, the hose H, which is wound in a spiral shape around the drum body 4B and bound with the binding wire 14, 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.

[0043] To close the flanges 4f on the free ends in the axial direction of the drum, the rods 7 are retracted as shown in Figures 9 and 10. This brings the cylinder bodies 6 close to the bases 4c. The flanges 4f rotate toward the base ends 6a of the cylinder bodies 6 to which they are connected, and are closed.

[0044] When the winding and removal processes are completed, a predetermined length of hose H is wound around the drum body 4A at the winding position P1, as shown in Figure 11. The drum body 4B at the removal position P2 is empty, with no hose H wound around it.

[0045] Next, as shown in Fig. 12, the arm 2 is rotated counterclockwise by 180° around the pivot 2a. As a result, as shown in Fig. 13, the drum body 4A with the hose H wound thereon is moved from the winding position P1 to the detaching position P2, and the empty drum body 4B is moved from the detaching position P2 to the winding position P1.

[0046] In the bundling process of this embodiment, the bundling guide 13b is inserted into the gap (distance L in plan view) between the rods 7 being extended in the drum circumferential direction. If the longitudinal directions of the fluid cylinders 5 were reversed, the base end 6a of each cylinder body 6 were connected to the base 4c, and the tip end 7a of each rod 7 were connected to the corresponding flange 4f via a link mechanism, the gap (distance L in plan view) where the bundling guide 13b is inserted would be the gap between the cylinder bodies 6 in the drum circumferential direction. In each fluid cylinder 5, the rod 7 has a smaller diameter than the cylinder body 6. The outer diameter of the rod 7 is smaller than the outer diameter of the cylinder body 6 by, for example, about 2 cm to 6 cm. Therefore, this embodiment is advantageous in ensuring a larger gap L.

[0047] That is, in this embodiment, the bundling guide 13b is inserted into the gap between the rods 7 in the drum circumferential direction, not the gap between the cylinder bodies 6, so a larger gap (distance L in plan view) can be secured for the bundling guide 13b to be inserted. This is advantageous for arranging the fluid cylinders 5 arranged in the inner peripheral space surrounded by the segments 4s of the drum bodies 4A, 4B closer to each other. As a result, the diameters of the drum bodies 4A, 4B can be easily reduced, thereby making it possible to further reduce the winding diameter of the hose H. The size of this gap (distance L in plan view) is, for example, 4 cm or more and 10 cm or less.

[0048] Conventionally, the number of fluid cylinders 5 arranged in the inner space surrounded by the segments 4s of each of the drum bodies 4A and 4B was four or more, but according to this embodiment, it is possible to reduce the number of fluid cylinders 5 arranged inside each of the drum bodies 4A and 4B to three, which makes it possible to further reduce the diameter of the drum bodies 4A and 4B and thereby make the winding diameter of the hose H even smaller.

[0049] When the arm 2 is rotated, the control unit 11 can also control the rotation drive motor 3 and the rotation drive motor 9a in conjunction with each other while the drum body 4A is being moved from the winding position P1 to the detaching position P2, as shown in Fig. 12, so that the wound hose H does not become unwound (to prevent unwinding). The control unit 11 controls the rotation drive motor 9a 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 8a.

[0050] Specifically, as illustrated in Figures 11, 12, and 13, the rotary drive motor 9a is controlled to rotate the drum body 4A around the rotary shaft 8a 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.

[0051] 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.

[0052] 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.

[0053] While the empty drum 4B is being moved from the removal position P2 to the reel-in position P1, the control unit 11 can control the rotation drive motor 3 and the rotation drive motor 9b in conjunction with each other to position the hose beginning end holder 10 provided on the drum 4B at a predetermined hose holding position. When the empty drum 4B is placed at the reel-in position P1, the position at which the hose beginning end holder 10 can easily hold the beginning end Ht of the hose H supplied from the hose supply unit 12 is set as this predetermined hose holding position.

[0054] By positioning the hose beginning end holding part 10 in this way, when the empty drum body 4B moves to the winding position P1, the beginning end Ht of the hose H supplied from the hose supply part 12 can be quickly held by the hose beginning end holding part 10. This allows the winding process to start immediately, which is even more advantageous for efficiently winding the hose H onto the drum body 4B.

[0055] In this embodiment, the arm 2 is alternately rotated 180° clockwise and 180° counterclockwise around 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 9a, 9b, flange 4f, and hose beginning end holder 10 to the respective devices via slip rings.

[0056] 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 9a, 9b, flange 4f, and hose start end holder 10 are connected to the respective devices via slip rings.

[0057] 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]
