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 efficiently wind a hose onto a drum body and more reliably prevent the hose wound onto the drum body from becoming unwound. [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] However, between the winding process and the bundling process, the hose wound onto the drum body is in an unstable state, not bound by the bundling body. If the arm is rotated in this state, the drum body rotates around its rotation axis, making the wound hose prone to unwinding. Therefore, in a winding device in which the arm rotates vertically, if the arm is rotated while its rotation around the drum body's rotation axis is locked, the circumferential position of the end of the hose wound onto the drum body changes as the arm rotates, which can cause the hose to unwind while the arm is rotating. Therefore, there is room for improvement in order to efficiently wind the hose onto the drum body while more reliably preventing the hose from unwinding. [Prior art documents] [Patent documents]

[0007] An object of the present invention is to provide a hose winding device and method that can efficiently wind a hose onto a drum body and more reliably prevent the hose wound onto the drum body from becoming unwound. [Means for solving the problem]

[0008] In order to achieve the above object, the hose reeling device of the present invention has a revolving shaft as a center. Up and downThe device has a rotatably supported arm, a rotation drive motor for rotating the arm about the rotation axis, and a drum body rotatably supported about a rotation axis 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 binding step is performed in which the hose wound onto the drum is bound with a binding wire, and a binding step is performed in which the hose bound with the binding wire in a wound state is bound with the binding wire. In a turret-type hose reeling device in which a removal process is performed in which a hose is removed from a drum body, each drum body is provided with a dedicated rotary drive motor, each drum body and its respective dedicated rotary drive motor are attached to the arm, and a control unit is provided which controls the swivel drive motor and each rotary drive motor, and the dedicated rotary drive motor for this drum body is controlled so that there is no relative rotation about its rotation axis of the drum body as it moves from the reeling position to the removal position by rotating the arm.

[0009] The hose winding method of the present invention is Up and downIn this hose winding method using a turret-type hose winding device, a drum body is rotatably supported by a rotating shaft at both longitudinal ends of a rotatably supported arm, and the arm is rotated to move each of the drum bodies between a winding position and a removal position, and at the winding position a winding process is performed in which a predetermined length of hose is wound onto the empty drum body, and at the removal position a binding process is performed in which the hose wound onto the drum is bound with a binding wire, and a removal process is performed in which the hose bound with the binding wire in a wound state is removed from the drum body.The method is characterized in that each of the drum bodies is provided with a dedicated rotation drive motor, and each of the drum bodies and its dedicated rotation drive motor are attached to the arm, and the dedicated rotation drive motor for this drum body is controlled by a control unit to eliminate relative rotation of the drum body about its rotation axis as the arm is rotated to move the arm from the winding position to the removal position. [Effects of the Invention]

[0010] According to the present invention, a turret-type hose reeling device is used, allowing for efficient reeling of the hose onto the drum. Furthermore, the dedicated rotary drive motor for each drum is attached to the arm along with the drum. Therefore, the dedicated rotary drive motor for that drum can be controlled to eliminate relative rotation around the rotation axis of the drum that rotates the arm to move it from the reeling position to the unreeling position. This control allows the terminal end of the hose reeled at the reeling position to be maintained at a predetermined position around the drum, which is advantageous for preventing the hose from becoming unwound.

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 3 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 rotation shafts 5a and 5b at both longitudinal ends of the arm 2, and a control unit 9. In the production line for hose H, a hose supply unit 10 is located upstream of the reeling device 1, and a bundling machine 11 is located downstream.

[0014] The position of the drum body 4A arranged on the hose supply unit 10 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 11 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 12, and a removal process is carried out in which the hose H, bound with the binding wire 12 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 rotation shaft 2a and rotates vertically around the rotation shaft 2a. The rotation shaft 2a is driven to rotate by a rotation drive motor 3. Various motors can be used as the rotation drive motor 3, such as a servo motor. In this embodiment, the rotation drive motor 3 is attached to a support post that is erected on a base.

[0018] The drums 4A and 4B have basically the same structure. Each drum 4A and 4B rotates around a respective rotation shaft 5a and 5b. The respective rotation shafts 5a and 5b are driven to rotate by respective rotation drive motors 6a and 6b. Therefore, each drum 4A and 4B can be rotated independently by its own dedicated rotation drive motor 6a and 6b. Each rotation drive motor 6a and 6b is a servo motor.

[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] The drum body 4A is made up of, for example, three or four segments 4s, each of which is formed by dividing a cylindrical body equally in the circumferential direction. A gap extending in the drum axial direction is formed between adjacent segments 4s in the circumferential direction. The outer surface of each segment 4s forms 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.

[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, the drum body 4A has four segments 4s, and a substantially rectangular plate-shaped flange 4f is provided at both ends of each segment 4s in the axial direction.

[0022] The drum body 4A is supported at one end by a rotary shaft 5a, which is connected to one end of the drum body 4A in the axial direction (the end where the rotary drive motor 6a is located). Therefore, the other end of the drum body 4A in the axial direction is a free end. Each flange 4f located on one end of the drum body 4A in the axial direction extends radially outward. These flanges 4f are fixed in a state where they 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 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 8. That is, the cables extending from the power source to the respective devices are held in the wire protection moving guide 8, such as a Cableveyor (registered trademark). As the arm 2 pivots, the cables held in the wire protection moving guide 8 move a predetermined length of stroke together with the wire protection moving guide 8. The wire protection moving guide 8 moves in a stroke in the up and down direction in FIG. 1.

[0026] The control unit 9 controls the movement of the swivel drive motor 3 and the rotary drive motors 6a and 6b. A known computer is used as the control unit 9. The control unit 9 also controls the movement of the hose start end holder 7, switching the flange portion 4f 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.

[0027] The hose supply unit 10 has a conveying mechanism 10a and a cutter 10b. A known belt conveyor or similar device is used as the conveying mechanism 10a. The manufactured hose H is placed on the conveying mechanism 10a and moved to be supplied to the winding device 1. The supplied hose H is cut to a predetermined length by the cutter 10b.

[0028] The bundling machine 11 bundles the hose H, which has been wound around the drum bodies 4A, 4B by the winding device 1, with a bundling wire 12 while it is wound up. Various known types of bundling machines can be used as the bundling machine 11. The bundling wire 12, guided out by bundling guides 11a, 11b of the bundling machine 11, bundles the hose H at the position of the gap extending in the axial direction of the drum, which is formed between circumferentially adjacent segments 4s.

[0029] An example of the procedure for winding up the hose H using this winding device 1 will now be described.

[0030] 1 and 2, one drum body 4A is positioned at a winding position P1, and the other drum body 4B is positioned at a removal position P2. At the winding position P1, a winding process is carried out in which a predetermined length of hose H is wound onto the empty drum body 4A, and at the removal position P2, a bundling process is carried out in which the hose H wound onto the drum 4B is bound with a binding wire 11, and a removal process is carried out in which the hose H bound with the binding wire 11 in a wound state is removed from the drum body 4B. The winding process, the bundling process, and the removal process are carried out in parallel.

[0031] During the winding process, the starting end Ht of the hose H supplied from the hose supply unit 10 is inserted between the outer circumferential surface of the drum body 4A and the hose starting end holder 7, and the hose starting end holder 7 moves closer to 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 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.

[0032] 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 10b 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.

[0033] In the bundling process, the bundling wire 11 led out from bundling guides 11a and 11b 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 11. The drum body 4B is sequentially rotated 90° around the rotation shaft 5b, and the hose H is similarly bundled with the bundling wire 11 at all locations (four locations in this embodiment) in the gaps between circumferentially adjacent segments 4s.

[0034] 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.

[0035] 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 4 and 5. This causes the flange 4f to no longer protrude outward from the outer circumferential surface of the drum.

[0036] Next, the hose H, which is wound around the drum body 4B in a spiral shape and bound with the binding wire 11, 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.

[0037] 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 6. The drum 4B at the removal position P2 is empty, with no hose H wound around it.

[0038] Next, as shown in Fig. 7, the arm 2 is rotated 180° counterclockwise around the pivot 2a. That is, the drums 4A and 4B are rotated up and down around the pivot 2a, and as shown in Fig. 8, the drum 4A with the hose H wound on it is moved from the winding position P1 to the detachment position P2, and the empty drum 4B is moved from the detachment position P2 to the winding position P1.

[0039] When the arm 2 is rotated, the rotation of the drum body 4A around the rotation axis 5a is controlled so that the wound hose H does not become unwound (does not come unwound). That is, the rotation of the drum body 4A around the rotation axis 5a is controlled so that the end He of the hose H is maintained at a predetermined position, for example, on the lower half side of the outer circumferential surface of the drum body 4A, so that the wound hose H does not become unwound (does not come unwound).

[0040] 7, while the drum body 4A is being moved from the winding position P1 to the detaching position P2, the control unit 9 controls the swing drive motor 3 and the rotation drive motor 6a in conjunction with each other. The control unit 9 controls the rotation drive motor 6a so as to eliminate relative rotation of the drum body 4A about the rotation shaft 5a as it is being moved from the winding position P1 to the detaching position P2.

[0041] 6, the rotation drive motor 6a is controlled to rotate the drum 4A about the rotation shaft 5a so that the end portion He of the hose H, which was located diagonally downward to the right of the outer periphery of the drum 4A at the winding position P1, is always located diagonally downward to the right of the outer periphery of the drum 4A while the drum 4A moves from the winding position P1 to the detaching position P2. If the rotation of the drum 4A about the rotation shaft 5a is locked while the drum 4A moves from the winding position P1 to the detaching position P2, the circumferential position of the end portion He on the drum 4A changes as the drum 4A rotates about the pivot axis 2a. The end portion He, which was located diagonally downward to the right of the outer periphery of the drum 4A at the winding position P1, changes its position in the drum circumferential direction so as to pass the position of the upper end of the outer periphery of the drum 4A as the drum 4A moves to the detaching position P2. If the circumferential position of the end portion He changes in this way, the hose H is likely to unwind from the end portion He and become unwound.

[0042] Meanwhile, in this embodiment, the end portion He, which was located diagonally downward to the right on the outer periphery of the drum body 4A, is maintained in this position diagonally downward to the right on the outer periphery of the drum body 4A as the drum body 4A moves to the removal position P2. That is, in FIGS. 6, 7, and 8, the end portion He of the hose H is maintained in this position diagonally downward to the right on the outer periphery of the drum body 4A. In this manner, the drum body 4A pivots from the winding position P1 to the removal position P2 while the end portion He is maintained in this position diagonally downward to the right on the outer periphery 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 periphery 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 the diagonally downward to the left on the outer periphery of the drum body 4A or at the bottom end of the outer periphery.

[0043] 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.

[0044] Thereafter, the arm 2 is similarly rotated to move each of the drums 4A, 4B between the winding position P1 and the detaching position P2, and the winding process at the winding position P1 and the bundling process and detaching process at the detaching position P2 are repeated in parallel, which is advantageous for efficiently winding the hose H onto the drums 4A, 4B.

[0045] Dedicated rotation drive motors 6a, 6b for each drum body 4A, 4B are attached to the arm 2 along with the respective drum bodies 4A, 4B. This makes it easy to control the rotation drive motors 6a, 6b to eliminate relative rotation about the rotation shafts 5a, 5b of the drum bodies 4A, 4B that are pivoting the arm 2 to move them from the winding position P1 to the removal position P2. As a result, the position of the terminal end He of the hose H wound at the winding position P1, as described above, in the circumferential direction of the drum can be maintained at a predetermined position where the hose H is less likely to become unwound, which is advantageous for more reliably preventing the hose H from becoming unwound.

[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 also control the rotation drive motor 3 and the rotation drive motor 6b in conjunction with each other. That is, the drum body 4B being moved from the removal position P2 to the winding position P1 is rotated about the rotation shaft 5b to position the hose start end holder 7 provided on the drum body 4B at a predetermined hose holding position.

[0047] When the empty drum body 4B is positioned at the winding position P1, the position at which the hose starting end holder 7 can easily hold the starting end Ht of the hose H supplied from the hose supply unit 10 is set as the predetermined hose holding position. In Figure 8, the hose starting end holder 7 is positioned at the upper end of the outer circumferential surface of the drum body 4B, and this position is set as the predetermined hose holding position.

[0048] 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 10 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.

[0049] In this embodiment, the arm 2 is alternately rotated 180° clockwise and 180° counterclockwise about the pivot shaft 2a, thereby moving each of the drum bodies 4A and 4B between the winding position P1 and the detaching position P2. Therefore, the cables that supply electricity to the rotation drive motors 6a and 6b, the flange 4f, and the hose beginning end holder 7 do not need to be connected to the respective devices via slip rings. Therefore, in this embodiment, these cables are held by the wire protection and movement guide 8, and are protected by moving the wire protection and movement guide 8 along with the rotation of the arm 2. Using a slip ring would make maintenance of the cables (electrical system) more complicated, so this embodiment improves maintainability.

[0050] 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.

[0051] In the above-described embodiment, the case where the pivot shaft 2a extends horizontally and the arm 2 pivots vertically is illustrated, but the pivot direction of the arm 2 is not limited to the vertical direction. For example, the present invention can also be applied to a winding device 1 in which the pivot shaft 2a extends vertically and the arm 2 pivots horizontally. [Explanation of symbols]
