Description

TECHNICAL FIELD 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 ART In a production line of hoses such as rubber hoses, hoses of a predetermined length are wound around a drum body for temporary storage and transportation (see, for example, Patent Document 1). There are various types of hose winding devices, and a turret type winding device is used to improve the efficiency of the hose winding process.

In a turret-type winding device, a drum body is rotatably supported on both ends of an arm about a rotation shaft. When the hose winding process for the drum body at one end of the arm is completed, the arm is turned around the turning shaft to move the drum body from the winding position to the drum body removal position and stand by at the removal position. The empty drum body that has been held 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 binding step of binding the hose wound around the drum body with a binding wire and then a removal step of removing the hose bound by the binding wire in the wound state from the drum body are performed. The hose removed from the drum body is transferred to a storehouse or the like.

Thus, in the turret-type winding device, while one drum is used for the winding process, the other drum is used for the binding process and the removing process. By performing different processes in parallel on each drum body, the series of processes from the start of winding the hose onto the drum body to the transport of the wound hose to the post-process in a state of binding with a binding wire can be efficiently performed. There is an advantage to be able to

By the way, since the hose is wound around the outer peripheral surface of the drum body, the winding diameter of the hose is determined by the outer diameter of the drum body to be used. There is an appropriate winding diameter according to hose specifications, but in order to obtain the desired winding diameter in the conventional winding device, it is necessary to prepare a drum body with a desired outer diameter. Then, a troublesome work of exchanging the drum body is required to attach the drum body corresponding to the desired winding diameter to the arm. In order to omit the replacement work of the drum body, if the drum body is configured to be expandable and retractable to make the outer diameter of the drum variable, the structure of the apparatus becomes complicated, resulting in a great cost. Therefore, there is room for improvement in easily changing the winding diameter of the hose.

BEST MODE FOR CARRYING OUT THE INVENTION The hose winding device and method of the present invention will be described below based on the embodiments shown in the drawings.

The embodiment of the hose winding device 1 illustrated in FIGS. It has drum bodies 4A and 4B rotatably supported by rotating shafts 5a and 5b at both ends thereof, and a control section 9. As shown in FIG. Further, the winding device 1 has a cylindrical large-diameter attachment 10 . The large-diameter attachment 10 is detachably attached to the outer peripheral sides of the drum bodies 4A and 4B. Details of the large-diameter attachment 10 will be described later. In the production line of the hose H, a hose supply section 13 is arranged upstream of the winding device 1, and a binding machine 14 is arranged downstream thereof.

The position of the drum body 4A arranged on the side of the hose supply section 13 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.

In this winding device 1, the respective drum bodies 4A and 4B are moved between the winding position P1 and the removing position P2 by rotating the arm 2 in the vertical direction. At the winding position P1, a winding step of winding a hose of a predetermined length onto the empty drum body 4A is performed. At the removal position P2, there is a binding step in which the hose H wound around the drum 4B is bound with the binding wire 15, and a removal step in which the hose H bound with the binding wire 15 in the wound state is removed from the drum body 4B. process is performed.

The hose H wound by the winding device 1 is of various types such as a rubber hose and a resin hose. For example, the winding device 1 winds up a reinforcing layer formed by spirally winding reinforcing cords made of metal or resin, or a hose H in which a reinforcing layer formed by braiding these reinforcing cords is embedded. . The outer diameter of the hose H is, for example, about 10 mm to 40 mm.

The arm 2 is connected to a swivel shaft 2a and swivels vertically around the swivel shaft 2a. Various motors can be used as the turning drive motor 3 for rotationally driving the turning shaft 2a, and for example, a servomotor is used. In this embodiment, a swing drive motor 3 is attached to a support post erected on a base.

The respective drum bodies 4A, 4B are rotationally driven by respective rotational driving motors 6a, 6b about respective rotating shafts 5a, 5b. A servomotor is used for each of the rotary drive motors 6a and 6b.

Each drum body 4A, 4B has a plurality of segments 4s and a plurality of flanges 4f connected to a base 4c that rotates together with the rotary shafts 5a, 5b. Since the respective drum bodies 4A and 4B have the same structure, the drum body 4A will be explained below.

As illustrated in FIGS. 4 and 5, four segments 4s constitute the drum body 4A, and each segment 4s has a shape obtained by equally dividing a cylindrical body in the circumferential direction. A gap extending in the axial direction of the drum is formed between the segments 4s adjacent to each other in the circumferential direction. The number of segments 4s is, for example, 3-4. The outer peripheral surface of each segment 4s serves as 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.

Flange portions 4f are arranged at both ends of the drum body 4A in the axial direction of the drum. More specifically, flange portions 4f are arranged at both ends in the axial direction of the drum for each segment 4s. In this embodiment, substantially rectangular plate-like flange portions 4f are arranged at both ends of each of the four segments 4s in the axial direction of the drum.

The drum body 4A is cantilevered on a rotary shaft 5a, and the rotary shaft 5a is connected to one side of the drum body 4A in the drum axial direction (the side on which the rotary drive motor 6a is arranged). Therefore, the other side of the drum body 4A in the axial direction of the drum is a free end. Each flange portion 4f arranged on one side of the drum body 4A in the axial direction of the drum extends outward in the radial direction of the drum. These flange portions 4f are composed of two plates, one of which is slidable in the radial direction of the drum with respect to the other. As a result, the length of these flange portions 4f in the radial direction of the drum is variable, and these flange portions 4f are set so as to always protrude outward from the outer peripheral surface of the drum body 4A (segment 4s). .

Each flange portion 4f arranged on the other side (free end side) of the drum body 4A in the drum axial direction extends outward in the drum radial direction and in a state in which it extends axially. can be switched to The flange portion 4f extending radially outward of the drum protrudes outward from the outer peripheral surface of the drum body 4A (segment 4s), and the flange portion 4f extending axially of the drum is It does not protrude to the outer peripheral side from the outer peripheral surface of the drum body 4A (segment 4s). For example, each flange portion 4f is connected to the drum body 4A (segment 4s ) is switched between a state in which it protrudes outward from the outer peripheral surface of ) and a state in which it does not protrude.

Further, the drum body 4A is provided with a hose start end holding portion 7 that moves toward and away from the outer peripheral 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 closer to the outer peripheral surface of the drum body 4A (segments 4s), the start end portion Ht of the hose H is held between the drum body 4A (segments 4s) and the outer peripheral surface of the drum body 4A (segments 4s). sandwiched and held.

In this embodiment, the winding device 1 further includes a hose detection sensor 8 arranged on the inner peripheral side of the drum body 4A, and a passage portion 4t that communicates the drum body 4A (segment 4s) in the drum radial direction. ing. As the hose detection sensor 8, various known non-contact sensors that emit detection light and receive detection light reflected by an object can be used. The passage portion 4t is a notch or a through hole. In this embodiment, an elongated notch extending in the axial direction of the drum serves as the passing portion 4t.

The hose detection sensor 8 emits detection light outward in the radial direction of the drum. When the hose H extends across the passage portion 4t on the outer peripheral surface of the drum body 4A, the detection light that has passed through the passage portion 4t is reflected by the hose H and passes through the passage portion 4t again. The light is received by the hose detection sensor 8 . In this manner, the hose detection sensor 8 is configured to detect whether or not the hose H is wound around the drum body 4A.

A detection signal from the hose detection sensor 8 is input to the controller 9 . The controller 9 operates the hose start end holder 7 based on this detection signal.

In this embodiment, the cables that supply electricity for the operation of the rotary drive motors 6a and 6b, the flange portion 4f, and the hose start end holding portion 7 are cableveyors (registered trademark), as illustrated in FIG. It is held by a wire protection movement guide 9a such as. As the arm 2 rotates, the cables held by the wire protection movement guide 9a move a stroke of a predetermined length together with the wire protection movement guide 9a. The wire protection movement guide 9a is stroke-moved in the vertical direction in FIG.

The control unit 9 controls the movement of the turning drive motor 3, the rotation drive motors 6a and 6b, and the hose start end holding portion 7, and the state in which the flange portion 4f protrudes outward from the outer peripheral surface of the drum body 4A and the state in which it does not protrude. control the movement to switch to A known computer is used as the control unit 9 .

The hose supply section 13 has a transport mechanism 13a and a cutter 13b. As the transport mechanism 13a, a known belt conveyor or similar equipment is used. The manufactured hose H is placed on the conveying mechanism 13 a to be moved and supplied to the winding device 1 . The supplied hose H is cut to a predetermined length by the cutter 13b.

The binding machine 14 binds the hose H wound around the drum bodies 4A and 4B by the winding device 1 with a binding wire 15 in a wound state. Various known types can be used as the binding machine 14 . A binding line 15 led out by binding guides 14a and 14b of a binding machine 14 binds the hose H at a gap extending in the axial direction of the drum formed between adjacent segments 4s in the circumferential direction.

An example of the procedure for winding the hose H using the winding device 1 will be described below.

As illustrated in FIGS. 1 and 2, at the winding position P1, a winding process is performed to wind the hose H of a predetermined length on the empty drum body 4A, and at the removing position P2, the hose H is wound onto the drum 4B. A binding step in which the wound hose H is bound with the binding wire 15 and a removal step in which the hose H bound by the binding wire 15 in a wound state is removed from the drum body 4B. The winding process, the binding process and the removing process are performed in parallel.

In the winding step, the starting end Ht of the hose H supplied from the hose supply part 13 is inserted between the hose starting end holding part 7 and the outer peripheral surface of the drum body 4A. When the leading end Ht of the hose H extends across the passage portion 4t on the outer peripheral surface of the drum body 4A (segment 4s), it is detected by the hose detection sensor 8, and this detection signal is sent to the control unit. 9.

When the controller 9 receives this detection signal and determines that the hose H is wound around the drum body 4A, the hose start end holder 7 moves from the state shown in FIG. 5 to the drum body 4A as shown in FIG. Move closer to the outer peripheral surface. As a result, the starting end portion Ht is sandwiched and held between the hose starting end holding portion 7 and the outer peripheral surface of the drum body 4A. In the winding process, the flange portions 4f at both end portions in the axial direction of the drum body 4A protrude from the outer peripheral surface of the drum toward the outer peripheral side.

Next, the rotary drive motor 6a is operated to rotate the drum body 4A about the rotating shaft 5a as illustrated in FIG. 3, thereby winding the hose H around the drum body 4A. The hose H, which is cut to a predetermined length by the cutter 13b at an appropriate timing, is spirally distributed on the outer peripheral surface of the drum body 4A between the flange portions 4f spaced apart in the axial direction of the drum body 4A. be wound up.

In the binding process, the binding wire 15 led out from the binding guides 14a and 14b is inserted into the drum body 4B in a gap extending in the drum axial direction formed between the segments 4s adjacent to each other in the circumferential direction of the drum body 4B. The hose H that is wound up in the cross section is traversed and wound repeatedly. As a result, the hose H spirally wound around the drum body 4B is bound by the binding wire 15 . The drum body 4B is sequentially rotated by 90° around the rotating shaft 5b, and the hose H is similarly tied by the binding wire 15 at all the gaps (four places in this embodiment) between the segments 4s adjacent in the circumferential direction. Band together.

In the bundling process, the flange portions 4f at both ends of the drum body 4B in the drum axial direction protrude from the outer peripheral surface of the drum toward the outer peripheral side. The hose start end holding portion 7 is moved away from the outer peripheral surface of the drum body 4B at an appropriate timing to release the hose start end portion Ht held by the hose start end holding portion 7 .

7 and 8, the flange portion 4f on the drum axial direction free end side of the drum body 4B is moved from the state extending outward in the drum radial direction. Switch to the state of extending in the axial direction of the drum. As a result, the flange portion 4f does not protrude from the drum outer peripheral surface to the outer peripheral side.

Next, the hose H, which has been spirally wound around the drum body 4B and bound by the binding wire 15, is moved to the free end side of the drum body 4B in the axial direction by using a known transfer device. Remove from Then, the hose H removed from the drum body 4B is transferred to a storehouse or the like by this transfer device.

When the winding process and the removing process are completed, the arm 2 is turned counterclockwise by 180° around the turning shaft 2a as illustrated in FIG. As a result, the drum body 4A around which the hose H is wound is moved from the winding position P1 to the removal position P2 as shown in FIG. move to

When rotating the arm 2, the drum body 4A is wound as shown in FIG. During the movement from the position P1 to the removal position P2, the controller 9 interlocks and controls the swing drive motor 3 and the rotation drive motor 6a. The control unit 9 controls the rotation drive motor 6a so that the drum body 4A, which is being moved from the winding position P1 to the removal position P2, does not rotate relative to the rotation shaft 5a.

Specifically, as illustrated in FIGS. 9 and 10, the end portion He of the hose H, which is located obliquely downward to the right of the outer peripheral surface of the drum body 4A at the winding position P1, is positioned at the winding position P1. While moving to the removal position P2, the drum body 4A is rotated around the rotation shaft 5a by controlling the rotation drive motor 6a so that the drum body 4A is always positioned obliquely downward to the right of the outer peripheral surface of the drum body 4A.

In this manner, the end portion He is maintained at a position obliquely lower right on the outer peripheral surface of the drum body 4A, where unwinding (unwinding) is unlikely to occur, while the drum body 4A pivots from the winding position P1 to the removing position P2. The position where the end portion He is maintained in the course of the drum body 4A turning from the winding position P1 to the removing position P2 is not limited to the position diagonally below the outer peripheral surface of the drum body 4A. Any position may be used as long as it is difficult for (rolling collapse) to occur. For example, the end portion He may be maintained at a position obliquely lower left on the outer peripheral surface of the drum body 4A or at a position at the lower end of the outer peripheral surface.

For the drum body 4A that has moved from the winding position P1 to the removal position P2, the above-described binding process and removal process for the drum body 4B are performed. For the drum body 4B that has moved from the removal position P2 to the winding position P1, the above-described winding process for the drum body 4A is performed. After the winding process and the removing process are completed, the arm 2 is turned clockwise around the turning shaft 2a to move the drum body 4B from the winding position P1 to the removing position P2, and the drum body 4A. is moved from the removing position P2 to the winding position P1.

While the empty drum body 4B is being moved from the removal position P2 to the winding position P1, the control unit 9 interlocks and controls the turning drive motor 3 and the rotation drive motor 6b to move the drum body 4B. The provided hose start end holder 7 can also be positioned at a predetermined hose holding position. When the empty drum body 4B is arranged at the winding position P1, the position where the hose start end holding part 7 can easily hold the start end Ht of the hose H supplied from the hose supply part 13 is this predetermined hose. Set as holding position.

By positioning the hose start end holding portion 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 portion 13 is quickly moved to the hose start end holding portion 7. can be held by Therefore, the winding process can be started immediately, which is more advantageous for efficiently winding the hose H onto the drum body 4B.

In this embodiment, the arm 2 is alternately rotated 180 degrees clockwise and 180 degrees counterclockwise about the rotation shaft 2a, thereby moving the drum bodies 4A and 4B to the winding position P1. and the removal position P2. Therefore, it is not necessary to connect the cables for supplying electricity for the operation of the rotary drive motors 6a and 6b, the flange portion 4f, and the hose start end holding portion 7 to the respective devices via slip rings. Therefore, in this embodiment, these cables are held by the wire protection movement guide 9a.

In order to move the respective drum bodies 4A and 4B between the winding position P1 and the unloading position P2, the arm 2 can be designed to rotate 360° around the pivot shaft 2a. That is, the arm 2 may be designed to be rotatable only in one direction, clockwise or counterclockwise, about the pivot 2a. With this specification, the cables that supply electricity for the operation of the rotary drive motors 6a and 6b, the flange portion 4f, and the hose start end holding portion 7 are connected to the respective devices via slip rings. .

When the winding diameter of the hose H is to be increased, as shown in FIG. 11, a detachable large-diameter attachment 10 is attached to the outer peripheral side of the drum body 4A. As illustrated in FIGS. 12 and 13, the drum body 10A is integrated with the attached large-diameter attachment 10. As shown in FIGS.

A large-diameter attachment 10 can be similarly mounted on the drum body 4B. The large-diameter attachment 10 is detachably attached to the outer peripheral side 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 peripheral side of the drum body 4A or to the outer peripheral side of the drum body 4B. A case of attaching and detaching the attachment 10 will be described.

More specifically, the large-diameter attachment 10 has a plurality of segments 11 as illustrated in FIGS. 11 to 13 . 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 equally dividing a cylindrical body in the circumferential direction. A gap extending in the axial direction of the drum is formed between the segments 11 adjacent in the circumferential direction.

When the large-diameter attachment 10 is attached to the outer peripheral side of the drum body 4A, the corresponding segment 11 is arranged on the outer peripheral side of each segment 4s. The gaps between the segments 4s adjacent in the circumferential direction and the gaps between the segments 11 adjacent in the circumferential direction corresponding to the segments 4s are arranged at the same positions in the drum circumferential direction. become. By mounting the attachment 10 on the outer peripheral side of the drum body 4A and integrating with the drum body 4A, the outer peripheral surface of each segment 11 becomes the outer peripheral surface of the drum around which the hose H is wound.

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 the spacer portion 12 in the radial direction of the drum, the outer diameter of the large-diameter attachment 10 can be varied.

The large-diameter attachment 10 (segment 11) is formed with an attachment passing portion 11t that communicates with the drum radial direction. The attachment passing portion 11t is a notch or a through hole. In this embodiment, an elongated notch extending in the axial direction of the drum serves as the attachment passing portion 11t.

Each segment 11 is integrated with the corresponding segment 4s located on the inner peripheral side by a connecting member such as a bolt. In this embodiment, the segment 11 and the segment 4s are coupled and integrated by a bolt that communicates the segment 11 and the spacer portion 12 and screws into the segment 4s.

When the large-diameter attachment 10 is attached to the outer peripheral side of the drum body 4A, it is positioned at a position where the passing portion 4t and the attachment passing portion 11t communicate with each other in the radial direction. That is, the segment 11 in which the attachment passing portion 11t is formed is attached to the segment 4s in 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 match. A hose detection sensor 8 is arranged on the inner peripheral side of the segment 4s where the passing portion 4t is formed.

Also when the large-diameter attachment 10 is attached to the outer peripheral side of the drum body 4A, the hose detection sensor 8 emits detection light outward in the radial direction of the drum as shown in FIG. When the hose H extends on the outer peripheral surface of the large-diameter attachment 10 (segment 11) crossing the attachment passing portion 11t, the detection light passing through the passing portion 4t and the attachment passing portion 11t is reflected by the hose H. Then, it passes through the attachment passage portion 11t and the passage portion 4t again and is received by the hose detection sensor 8. In this manner, 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).

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

When the controller 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, the controller 9 moves the hose start end holder 7 from the state shown in FIG. is moved closer to the outer peripheral surface of the large-diameter attachment 10 (segment 11). As a result, the starting end portion Ht is sandwiched and held between the hose starting end holding portion 7 and the outer peripheral surface of the large-diameter attachment 10 (segment 11).

In the winding process, the flange portions 4f at both end portions of the drum body 4A in the drum axial direction protrude from the outer peripheral surface of the large-diameter attachment 10 to the outer peripheral side. In this embodiment, in each flange portion 4f arranged on one side in the drum axial direction of the drum body 4A, one plate slides outward in the drum radial direction with respect to the other plate. As a result, these flange portions 4f can be made to protrude further to the outer peripheral side than the outer peripheral surface of the large-diameter attachment 10 (segment 11).

Even when the large-diameter attachment 10 is attached to the outer peripheral side of the drum body 4A, the winding process, the binding process, and the removal process are performed in the same manner as when the large-diameter attachment 10 is not attached. In order to reduce the winding diameter of the hose H, the attached large-diameter attachments 10 (each segment 11) may be removed from the drum body 4A.

Thus, the drum body 4A with the large-diameter attachment 10 mounted on the outer peripheral side is integrated with the large-diameter attachment 10, and the outer diameter becomes the outer diameter of the large-diameter attachment 10, so the winding diameter of the hose H is increased. be able to. Therefore, by attaching and detaching the large-diameter attachment 10 to and from the drum body 4A, the winding diameter of the hose H wound around the drum body 4A can be easily changed.

In this embodiment, the hose detection sensor 8 is arranged on the inner peripheral side of the segment 4s of the drum bodies 4A and 4B, the segment 4s is formed with a passage portion 4t, and the segment 11 is formed with an attachment passage portion 11t. there is As a result, the hose H is attached to the drum bodies 4A and 4B (the large-diameter attachment 10 mounted to the drum bodies 4A and 4B) regardless of whether or not the large-diameter attachment 10 is mounted on the drum bodies 4A and 4B. ) can be grasped.

Further, in this embodiment, the passage portion 4t and the attachment passage portion 11t are shaped to extend in the axial direction of the drum. Therefore, the segments 4s, 11 is slightly displaced in the axial direction of the drum, the detection light of the hose detection sensor 8 can easily pass through the passage portion 4t and the attachment passage portion 11t.
