[Technical field]

[0001] It relates to a wire transport device that holds and transports wires. [Background technology]

[0002] Conventionally, in the manufacture of wire harnesses for automobiles and the like, when performing end processing such as connecting a crimp terminal to the end of an electric wire, an electric wire conveying device that holds and conveys the electric wire has been used (see, for example, Patent Documents 1 and 2).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 09-328212 [Patent Document 2] JP 2012-126493 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned electric wire transport device, the tip of the electric wire may sag vertically due to its own weight during transport. Such sagging during transport may be noticeable when transporting a thick electric wire for high voltage. In the case of end processing such as connecting a crimp terminal, the tip of the electric wire is often in a state where the core wire is exposed by stripping. If the electric wire is transported with the tip sagging, the core wire may come into contact with peripheral equipment, crimp terminals, or other components during transport, causing fraying, which is undesirable.

[0005] Therefore, in view of the above-mentioned problems, an object of the present invention is to provide an electric wire transport device capable of transporting an electric wire while suppressing sagging of the tip portion. [Means for solving the problem]

[0006] In order to solve the above problems, the wire transporting device is characterized by comprising: a wire holding part that holds a held part of the wire that is away from the tip so that the held part is aligned in a horizontal direction; a transporting part that transports the wire holding part holding the wire to a processing position where a predetermined tip processing is performed on the tip; and a tip side support part that supports a supported part of the wire held in the wire holding part that is closer to the tip than the held part from below in the vertical direction, and is transported by the transporting part together with the wire holding part. Effect of the Invention

[0007] According to the above electric wire transport device, it is possible to transport the electric wire while preventing the tip portion from sagging. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An embodiment of the wire transport device will be described below.

[0010] FIG. 1 is a schematic diagram showing a wire transport device according to an embodiment.

[0011] The electric wire transport device 1 of this embodiment is a device that holds an electric wire W1 and transports it to a crimping machine 2 when performing end processing such as connecting a crimp terminal W12 to the end portion W11 of the electric wire W1 using a crimping machine 2 in the manufacture of wire harnesses for automobiles, etc.

[0012] The crimping machine 2, which is the destination of the conveyance, is provided with an anvil 21 disposed below in the vertical direction D11 on which the crimp terminal W12 is placed, and a crimper 22 as an upper die. The electric wire conveying device 1 conveys the electric wire W1, the tip portion W11 of which has been stripped to expose the core wire W111, to the crimping machine 2, and positions the tip portion W11 above the crimp terminal W12 on the anvil 21. Then, the crimper 22 descends in the crimping direction D12, and applies pressure to the crimp terminal W12 and the tip portion W11 of the electric wire W1 between the anvil 21 and the crimp terminal W12, thereby connecting the crimp terminal W12.

[0013] The electric wire transport device 1 used for such end processing includes an electric wire holding unit 11, a transport unit 12, an end side support unit 13, a mounting unit 14, an electric wire stretch absorbing mechanism 15, and a support unit moving mechanism 16.

[0014] The wire holding portion 11 holds the held portion W13 of the wire W1, which is separated from the tip portion W11, so that the held portion W13 is aligned in a horizontal direction D13. The wire holding portion 11 has a chuck mechanism that clamps the held portion W13 with a pair of gripping jaws 111 in a direction intersecting both the vertical direction D11 and the wire length direction D14 of the wire W1.

[0015] The conveying section 12 conveys the electric wire holding section 11 holding the electric wire W1 and the tip side support section 13 to a crimping processing position P11 where the crimp terminal W12 can be connected to the tip section W11. The conveying section 12 is a belt conveyor that conveys the electric wire holding section 11 and the tip side support section 13 via a mounting section 14, and has a conveying belt 121 that moves along a horizontal direction D13 and in a conveying direction D15 that intersects with the wire length direction D14.

[0016] The tip side support part 13 is a part that supports the supported part W14, which is closer to the tip part W11 than the held part W13, of the electric wire W1 held by the electric wire holding part 11 from below in the vertical direction D11. The tip side support part 13 supports the supported part W14 so that the electric wire W1 is linear from the held part W13 to the tip part W11. The tip side support part 13 is transported by the transport part 12 together with the electric wire holding part 11. In this embodiment, the tip side support part 13 has a band-like shape that extends so as to intersect with the electric wire W1, and a recess 131 that receives the supported part W14 is formed on a side edge on one end side of the band-like tip side support part 13. The other end side of the band-like tip side support part 13 is supported by a support part moving mechanism 16.

[0017] The mounting unit 14 is a portion on which the electric wire holding unit 11 and the tip side support unit 13 are mounted. Here, the tip side support unit 13 is mounted on the mounting unit 14 together with the electric wire holding unit 11 via a support unit movement mechanism 16. The mounting unit 14 includes a mounting portion 141 and a vertical movement mechanism 142.

[0018] The mounting portion 141 is a plate-like portion on which the electric wire holding portion 11 and the support portion moving mechanism 16 supporting the tip side support portion 13 are mounted. The electric wire holding portion 11 and the support portion moving mechanism 16 (i.e., the electric wire holding portion 11 and the tip side support portion 13) are mounted on this mounting portion 141 in a state in which they can move in the wire length direction D14 of the electric wire W1 held by the electric wire holding portion 11. This movably mounting is achieved by attaching the electric wire holding portion 11 so as to fit into a pair of rail portions 141a formed on the upper surface of the mounting portion 141 in the wire length direction D14.

[0019] The vertical movement mechanism 142 is a mechanism that moves the mounting portion 141 in the vertical direction D11 by a cylinder. In this embodiment, the vertical movement mechanism 142 is fixed to the conveyor belt 121 in the conveyor unit 12, and moves in the conveyor direction D15 together with the conveyor belt 121. The vertical movement mechanism 142 positions the mounting portion 141 at a conveying height higher than a processing height at which the crimp terminal W12 can be connected to the tip portion W11 until the electric wire holding portion 11 reaches the crimping processing position P11 by being conveyed by the conveyor unit 12. Then, when the electric wire holding portion 11 reaches the crimping processing position P11, the vertical movement mechanism 142 lowers the mounting portion 141 to that processing height.

[0020] The wire stretch absorbing mechanism 15 is a spring member provided in the mounting portion 141 of the mounting unit 14. Here, the connection of the crimp terminal W12 by the crimping machine 2 is a process that involves stretching of the electric wire W1 in the wire length direction D14 during crimping. The wire stretch absorbing mechanism 15 biases the electric wire holding portion 11 toward the tip portion W11, and absorbs the stretch by allowing the electric wire holding portion 11 to move in a direction away from the tip portion W11 when stretching occurs in the electric wire W1 due to the connection of the crimp terminal W12. The wire stretch absorbing mechanism 15 is a coil spring interposed in a compressed state between the electric wire holding portion 11 and a standing wall portion 141b provided on the edge of the mounting portion 141 on the conveyor belt 121 side. The wire stretch absorbing mechanism 15 biases the wire holding portion 11 in the stretching direction of the coil spring, and when the wire holding portion 11 is pushed back by the stretching of the wire W1, the coil spring is compressed, thereby absorbing the stretch.

[0021] The support part moving mechanism 16 is a mechanism that connects the tip side support part 13 to the electric wire holding part 11 and moves the tip side support part 13 in the wire length direction D14 of the electric wire W1 by a cylinder. The support part moving mechanism 16 includes a drive part 161 connected to the electric wire holding part 11 and a support arm 162 that extends from the drive part 161 in the wire length direction D14 and supports an end of the band-shaped tip side support part 13 at the tip. The support part moving mechanism 16 moves the tip side support part 13 in the wire length direction D14 by moving the support arm 162 in the wire length direction D14 by the drive part 161. The support part moving mechanism 16 moves the tip side support part 13 from the initial position P12 to the support position P13 at any timing until the electric wire holding part 11 reaches the crimping processing position P11 by the conveyance by the conveyance part 12. The supporting position P13 is a position for supporting the supported portion W14 of the electric wire W1, and the initial position P12 is a position closer to the electric wire holding portion 11 than the supporting position P12.

[0022] Next, a series of operations from when the electric wire W1 is set on the electric wire transport device 1 described above until when it is transported to the crimping machine 2 and connected to the crimp terminal W12 will be described below.

[0023] FIG. 2 is a diagram showing a state in which an electric wire is set in the electric wire transport device shown in FIG. 1 and the electric wire is supported by a tip side support part.

[0024] First, in a first step S11, the electric wire W1 is set on the electric wire transport device 1. At this stage, the electric wire holding part 11 is positioned by the transport part 12 at a position away from the crimping machine 2 on the rear side in the transport direction D15. The tip side support part 13 is positioned by the support part movement mechanism 16 at an initial position P12 closer to the electric wire holding part 11. Furthermore, the mounting part 141 on which the electric wire holding part 11 and the tip side support part 13 are placed is positioned by the vertical movement mechanism 142 at a transport height H11 in the vertical direction D11 that is higher than a processing height at which the crimp terminal W12 can be connected. When the electric wire W1 is held by the electric wire holding part 11 in this state, the tip part W11 hangs down in the vertical direction D11 due to its own weight.

[0025] In the next second step S12, the support part moving mechanism 16 in the electric wire transport device 1 moves the tip side support part 13 in the forward direction D141 along the wire length direction D14 to a support position P13 where the tip side support part 13 supports the supported part W14 of the electric wire W1. This movement of the tip side support part 13 lifts the tip part W11 of the electric wire W1 that was hanging down in the first step S11, and the electric wire W1 becomes linear from the held part W13 to the tip part W11.

[0026] FIG. 3 is a diagram showing how the electric wire held in the state of the second step in FIG. 2 is conveyed to the crimping machine and the tip portion is placed on the crimp terminal.

[0027] 2, in the electric wire conveying device 1, the electric wire holding part 11 that holds the electric wire W1 and the tip side support part 13 that supports the electric wire W1 are conveyed in the conveying direction D15 by the conveying part 12 via the support part moving mechanism 16 and the mounting part 14. This conveying is continued until the electric wire holding part 11 and the tip side support part 13 reach the crimping processing position P11 where the tip part W11 of the electric wire W1 is positioned directly above the crimp terminal W12 set in the crimping machine 2.

[0028] In the next fourth step S14, the mounting portion 141 carrying the electric wire holding portion 11 and the tip side support portion 13 that have reached the crimping processing position P11 is lowered in a descending direction D111 along the vertical direction D11 by the vertical movement mechanism 142 in the mounting portion 14 of the electric wire transport device 1. This descent is continued until the mounting portion 141 reaches a processing height H12 at which the tip portion W11 of the electric wire W1 descends in the descending direction D111 and fits into the barrel W121 of the crimp terminal W12 in the crimping machine 2, enabling connection of the crimp terminal W12.

[0029] FIG. 4 is a diagram showing how the crimp terminal is connected to the tip of the electric wire accommodated in the barrel of the crimp terminal by a crimping machine in the fourth step of FIG.

[0030] In a fifth step S15 following the fourth step S14 in FIG. 3, the crimper 22 descends in a crimping direction D12 toward the tip W11 of the electric wire W1 that has been accommodated in the barrel W121 of the crimp terminal W12 on the anvil 21 of the crimping machine 2 by being transported by the electric wire transport device 1.

[0031] In the next sixth step S16, the crimper 22 clamps the crimp terminal W12 and the tip portion W11 of the electric wire W1 between the anvil 21 and the crimper 22 and applies pressure to connect the crimp terminal W12. At this time, the pressure applied by the crimping machine 2 causes the electric wire W1 to elongate in the wire length direction D14. Here, the tip portion W11 is fixed by the crimping machine 2, and the wire W1 is linear from the tip portion W11 to the held portion W13 of the electric wire holding part 11. Therefore, in the electric wire transport device 1, the electric wire holding part 11 is pushed by the elongation of the electric wire W1 and moves together with the tip side support part 13 in the elongation direction D142 away from the crimping machine 2 along the wire length direction D14. This movement compresses the electric wire elongation absorbing mechanism 15, which is a coil spring, and absorbs the elongation.

[0032] FIG. 5 is a diagram showing how the tip end with the terminal is removed from the crimping machine after the crimp terminal has been crimped in the sixth step of FIG.

[0033] 4, in a seventh step S17, the crimper 22 after crimping in the crimping machine 2 moves in a crimper upward direction D16 away from the anvil 21 to release the crimped crimp terminal W12. This release releases the restriction on the tip part W11 with the terminal, so that in the electric wire transport device 1, the electric wire holding part 11 moves together with the tip side support part 13 in the biasing direction D143 along the wire length direction D14 by the biasing force from the electric wire stretch absorbing mechanism 15. During this movement, the crimped terminal W12 on the anvil 21 also moves together with the electric wire W1 in the biasing direction D143.

[0034] In the next eighth step S18, in the mounting part 14 of the electric wire transport device 1, the vertical movement mechanism 142 raises the mounting part 141 on which the electric wire holding part 11 and the tip side support part 13 are placed in a mounting ascent direction D112 along the vertical direction D11 to a transport height H11. Due to this ascent, the tip part W11 of the electric wire W1 and the crimped crimp terminal W12 are also raised, taken out of the crimping machine 2, and transported by the transport part 12 in the transport direction D15.

[0035] According to the electric wire conveying device 1 of the embodiment described above, the electric wire W1 is conveyed in a state in which the supported portion W14, which is closer to the tip portion W11 than the held portion W13 held by the electric wire holding portion 11, is supported from below in the vertical direction D11 by the tip side support portion 13. This support from below by the tip side support portion 13 suppresses sagging of the tip portion W11 of the electric wire W1 due to its own weight. In this way, according to the electric wire conveying device 1 described above, the electric wire W1 can be conveyed while suppressing sagging of the tip portion W11. Furthermore, by suppressing this sagging, contact between the tip portion W11 and peripheral equipment and various members during conveyance can be effectively suppressed. In addition, since the supported portion W14 close to the tip portion W11 is supported, the tip portion W11 of the electric wire W1 can be effectively positioned at an optimal position for connecting the crimp terminal W12.

[0036] In this embodiment, the conveying unit 12 conveys the electric wire holding unit 11 and the tip side support unit 13 via the mounting unit 14 on which the electric wire holding unit 11 and the tip side support unit 13 are mounted. According to this configuration, by passing the electric wire W1 through the mounting unit 14, the tip side support unit 13 can suppress sagging of the tip portion W11, and the electric wire W1 can be conveyed in a stable state.

[0037] In this embodiment, the connection of the crimp terminal W12 is a process that involves stretching of the electric wire W1. The tip side support portion 13 supports the supported portion W14 so that the electric wire W1 is linear from the held portion W13 to the tip portion W11. The electric wire stretch absorbing mechanism 15 biases the electric wire holding portion 11, which is movable in the wire length direction D14, toward the tip portion W11, and absorbs the stretch by allowing the electric wire holding portion 11 to move in a direction away from the tip portion W11 when the electric wire W1 stretches. With this configuration, the position of the electric wire holding portion 11 during transportation can be stabilized by the biasing force of the electric wire stretch absorbing mechanism 15. When the electric wire W1 stretches due to the connection of the crimp terminal W12, the electric wire holding portion 11 is moved in the wire length direction D14, so that the electric wire stretch absorbing mechanism 15 can effectively absorb the stretch without impeding the stretch. In addition, during this absorption, the electric wire W1 is made straight from the held portion W13 to the tip portion W11 by the tip side support portion 13, so that in this respect too, the elongation caused by the movement of the electric wire holding portion 11 in the wire length direction D14 can be effectively absorbed.

[0038] In this embodiment, the mounting unit 14 includes a mounting portion 141 of the electric wire holding unit 11 and the tip end support unit 13, and a vertical movement mechanism 142 that moves the mounting portion 141 in the vertical direction D11. The vertical movement mechanism 142 positions the mounting portion 141 at a higher transport height H11 until the electric wire holding unit 11 reaches the crimping processing position P11, and lowers the mounting portion 141 to a lower processing height H12 when the electric wire holding unit 11 reaches the crimping processing position P11. According to this configuration, the mounting portion 141 is positioned at the higher transport height H11 until the electric wire holding unit 11 reaches the crimping processing position P11, so that the tip end W11 of the electric wire W1 is also positioned at a higher position and transported. This transport can further reduce contact between the tip end W11 and peripheral equipment and various members during transport.

[0039] In this embodiment, a support moving mechanism 16 is provided that connects the tip side support part 13 to the electric wire holding part 11 and moves the tip side support part 13 in the wire length direction D14 of the electric wire W1. The support moving mechanism 16 moves the tip side support part 13 from an initial position P12 close to the electric wire holding part 11 to a support position P13 on the tip part W11 side at any timing until the electric wire holding part 11 reaches the crimping processing position P11. According to this configuration, even if there are peripheral equipment or various members that may come into contact with the tip side support part 13 during the transport until the electric wire holding part 11 reaches the crimping processing position P11, the tip side support part 13 is retreated to the initial position P12. By transporting the electric wire holding part 11 in this retreated state, it is possible to effectively avoid contact between the tip side support part 13 and the peripheral equipment or various members.

[0040] The above-described embodiment is merely a representative example of the electric wire transport device, and the electric wire transport device is not limited to this embodiment but can be modified in various ways.

[0041] For example, in the above-described embodiment, an electric wire conveying device 1 that holds an electric wire W1 and conveys it to a crimping machine 2 so that a crimp terminal W12 can be connected to an end W11 of an electric wire W1 for a wire harness for an automobile by the crimping machine 2 is exemplified as an example of an electric wire conveying device. However, the electric wire conveying device is not limited to this, and the specific use of the electric wire to be conveyed is not limited to this. Furthermore, the end processing performed on the end of the electric wire at the conveying destination is not limited to the connection of a crimp terminal by the crimping machine, and any end processing such as stripping of the coating can be adopted.

[0042] In the above-described embodiment, as an example of the electric wire holding part, the electric wire holding part 11 having a chuck mechanism that clamps the electric wire W1 with a pair of gripping claws 111 is exemplified. However, the electric wire holding part is not limited to this, and any specific mechanical configuration is not required.

[0043] In the above-described embodiment, the conveying unit 12 having the conveying belt 121 is exemplified as an example of the conveying unit. However, the conveying unit is not limited to this, and may have a conveying chain instead of the conveying belt, and the specific mechanical configuration is not important.

[0044] In the above-described embodiment, the conveying unit 12 that conveys the electric wire holding unit 11 and the tip side support unit 13 via the mounting unit 14 on which the electric wire holding unit 11 and the tip side support unit 13 are mounted is exemplified as an example of the conveying unit. However, the conveying unit is not limited to this, and may be, for example, a mechanism that conveys the electric wire holding unit and the tip side support unit individually. However, as described above, by conveying the electric wire W1 via the mounting unit 14, the sagging of the tip portion W11 is suppressed by the tip side support unit 13, so that the electric wire W1 can be conveyed in a stable state.

[0045] In the above-described embodiment, the electric wire transport device 1 is exemplified as an example of the electric wire transport device, in which the tip side support part 13 supports the tip side of the electric wire W1 in a straight line, and the electric wire stretch absorbing mechanism 15 biases the electric wire holding part 11 and absorbs the stretch of the electric wire W1. However, the electric wire transport device is not limited to this, and the tip side support part may support the electric wire in a state where some sagging of the tip side is allowed, and an absorbing mechanism for the stretch of the electric wire may not be provided. However, as described above, by making the tip side of the electric wire W1 straight and configuring the electric wire stretch absorbing mechanism 15 to absorb the stretch, the stretch of the electric wire W1 can be effectively absorbed without being hindered. In the present embodiment, the electric wire stretch absorbing mechanism 15 is exemplified as an example of the electric wire stretch absorbing mechanism. However, the electric wire stretch absorbing mechanism is not limited to this, and may be, for example, a mechanism that absorbs the stretch by moving the electric wire holding part in the stretching direction of the electric wire by a cylinder or a servo motor.

[0046] In the above-described embodiment, as an example of the mounting part of the electric wire holding part and the tip side support part, the mounting part 14 is exemplified as a vertical movement mechanism 142 that lowers the mounting part 141 to a lower processing height H12 when the electric wire holding part 11 reaches the crimping processing position P11. However, the mounting part is not limited to this, and may not be provided with a vertical movement mechanism in particular, and may simply be mounted on the electric wire holding part and the tip side support part to mediate the transportation by the transport part. However, as described above, according to the mounting part 14 that is mounted so as to move the electric wire holding part 11 and the tip side support part 13 in the vertical direction D11, contact between the tip part W11 and peripheral equipment and various members during transportation can be further suppressed. In addition, in the present embodiment, as an example of the vertical movement mechanism, the vertical movement mechanism 142 that moves the mounting part 141 with a cylinder is exemplified. However, the vertical movement mechanism is not limited to this, and may be, for example, a mechanism that moves the mounting part with a servo motor.

[0047] In the above-described embodiment, the electric wire transport device 1 in which the support part moving mechanism 16 moves the tip side support part 13 from the initial position P12 close to the electric wire holding part 11 to the support position P13 on the tip side is exemplified as an example of the electric wire transport device. However, the electric wire transport device is not limited to this, and may not particularly include the support part moving mechanism, and the tip side support part may be fixed to the support position on the tip side. However, as described above, by moving the tip side support part 13 between the initial position P12 and the support position P13 by the support part moving mechanism 16, contact between the tip side support part 13 and peripheral equipment and various members during transport can be effectively avoided. In addition, in the present embodiment, the support part moving mechanism 16 that moves the tip side support part 13 by a cylinder is exemplified as an example of the support part moving mechanism. However, the support part moving mechanism is not limited to this, and may be, for example, a mechanism that moves the tip side support part by a servo motor. [Explanation of symbols]
