[0079] Hereinafter, an embodiment of the wire harness manufacturing apparatus will be described.

[0080] Figure 1 is a schematic external perspective view showing a wire harness manufacturing device according to the embodiment, and Figure 2 It is shown Figure 1 Schematic plan view of a sliding portion, a base end holding portion, and their surrounding structures in the wire harness manufacturing device shown. Figure 3 It is shown by Figure 1 and Figure 2 The schematic diagram of an example of a wire harness manufactured by the wire harness manufacturing apparatus shown.

[0081] The wire harness manufacturing device 1 according to the present embodiment is configured to automatically manufacture Figure 3 The example shown is a branch-shaped device of the wire harness W1.

[0082] The wire harness W1 as a manufacturing target is installed and routed in a vehicle to connect multiple devices inside the vehicle. The wire harness W1 includes multiple front connectors W11, multiple rear connectors W12, multiple tape winding parts W13, multiple exterior parts W14, and multiple fixing clamps W15.

[0083] The front-end connector W11 is a connector that moves in the sliding direction D11 while being held by the sliding portion 12 in the wiring harness manufacturing device 1 described below, and serves as a connector on the front-end side that moves. On the other hand, the rear-end connector W12 is a connector that does not move in the sliding direction D11 while being held by the base-end holding portion 13 described below, and serves as a connector on the base-end side. Here, according to the present embodiment, the wiring harness W1 as a manufacturing target is constructed by combining a plurality of sub-wiring harnesses W1a composed of one or more electric wires W16, wherein both ends of the electric wire W16 are composed of the front-end connector W11 and the rear-end connector W12. This combination is achieved by forming a tape winding portion W13 and an outer casing portion W14, and attaching a fixing clamp W15.

[0084] The tape winding portion W13 is a portion where the electric wires W16 of the plurality of sub-wiring harnesses W1a are selectively bundled to be wound by the tape W131. Figure 3 In the example shown, first, a tape wrapping portion W13 is formed at both ends of the main line portion W1b in which all the electric wires W16 of the sub-wiring harness W1a are bundled. The main line portion W1b is bifurcated into two branches, and then further bifurcated into two branches at the rear end connector W12 side, but a tape wrapping portion W13 is also formed at the end of the rear end connector W12 side in the middle line portion W1c sandwiched between the two branches. The exterior portion W14 is formed at two locations, including a location where the electric wires W16 of the main line portion W1b are accommodated in a corrugated tube W141 and a location where the electric wires W16 of the middle line portion W1c are accommodated in the corrugated tube W141. The fixing clamp W15 is a component for joining and fixing the wiring harness W1 to a predetermined fixing destination, and is used at a predetermined fixing destination. Figure 3 In the example shown, the fixing clamp W115 is attached to the exterior portion W14 at two locations.

[0085] Figure 1 and Figure 2 The wire harness manufacturing device 1 shown is a device for automatically manufacturing the above-mentioned wire harness W1, and includes a device frame 11, a slide portion 12, a base end holding portion 13, and a wire processing portion 14. The wire harness manufacturing device 1 also includes a sub-wire harness supply vehicle 15 and a reference Figures 6 to 8 The external mounting plate 16 and the electric wire guide portion 17 described below are components that are appropriately installed and constructed later on the device frame 11 .

[0086] The device frame 11 is a part for holding various parts of the wire harness manufacturing device 1, and includes a bottom plate portion 111, a top plate portion 112, and a support portion 113. The bottom plate portion 111 and the top plate portion 112 are rectangular plate-like parts of the same shape, wherein their corners are connected to each other by four square column-shaped support portions 113.

[0087] The bottom plate portion 111 includes an upper surface that serves as a reference surface 111a in the harness manufacturing device 1, and is a component placed at a predetermined installation position in such a manner that the reference surface 111a extends along a horizontal surface. In the reference surface 111a, the lower end of the support portion 113 is connected to its corner, and two arm rails 111b are formed so that the two robot arms 141 described below move along a straight line in the sliding direction D11 along the long side of the rectangular reference surface 111a. Each arm rail 111b is arranged so that each robot arm 141 moves along a straight line between the first end side 1a and the second end side 1b in the sliding direction D11 in the harness manufacturing device 1. Then, the two arm rails 111b are arranged so that the two robot arms 141 move along a straight line in parallel with each other in the arrangement direction D12 along the short side of the reference surface 111a.

[0088] The top plate portion 112 includes a lower surface as a top surface 112a on which the sliding portion 12 and the like are arranged, and is a component placed so that the top surface 112a is located at a predetermined top height H11 from the reference surface 111a of the bottom plate portion 111 while facing the reference surface 111a. In the top surface 112a, the upper end of the pillar portion 113 is connected to its corner, and a plurality of sliding rails 112b are formed so that the plurality of sliding portions 12 move linearly in the sliding direction D11 along the long side of the rectangular top surface 112a. Each sliding rail 112b is arranged so that each sliding portion 12 moves linearly between the first end side 1a and the second end side 1b of the wire harness manufacturing device 1. Then, such sliding rails 112b are arranged in plurality so that the plurality of sliding portions 12 move linearly in a manner parallel to each other in the arrangement direction D12 along the short side of the top surface 112a. Furthermore, in the arrangement direction D12, the area near a pair of side edges adjacent to the outer sides of the plurality of slides 12 becomes a standby position of a processing mechanism 142 described below that is selectively held by the robot arm 141. Each standby position 112c is an area where every three of the processing mechanisms 142 are arranged in the sliding direction D11 and stand by.

[0089] As described above, the support column 113 is formed as four corner columns to connect the corners of the reference surface 111a in the bottom plate portion 111 and the corners of the top surface 112a in the top plate portion 112 in the up-down direction D13. The length of each support column 113 is a length that allows the top surface 112a to be located above a predetermined top height H11 from the reference surface 111a. The top height H11 is a height at which the electric wire W16 does not contact the reference surface 111a when the electric wire W16 hangs down to the maximum expected length during the manufacturing of the wire harness W1 in the wire harness manufacturing apparatus 1.

[0090] The device frame 11, in which the bottom plate portion 111 and the top plate portion 112 are connected by four support portions 113, generally has a rectangular parallelepiped frame structure with open sides, and the manufacturing of the wire harness W1 is performed on the top surface 112a inside thereof. Here, the manufacturing of the wire harness W1 is performed by holding the wire ends by the sliding portion 12 and the base end holding portion 13 and by wire processing including branching by the wire processing portion 14.

[0091] The sliding parts 12 are attached one by one to the multiple sliding rails 112b of the top surface 112a so as to be able to rotate around the rotation axis 121. Then, the sliding parts 12 are arranged parallel to each other in the arrangement direction D12, and move in a straight line on the sliding rails 112b between the first end side 1a and the second end side 1b in the sliding direction D11. Each sliding part 12 is a component that holds the front end connector W11 of the above-mentioned sub-wiring harness W1a one by one so as to be able to open toward the reference surface 111a side. The sliding part 12 holds one end of at least one electric wire W16, that is, one end of the number of electric wires W16 connected to the front end connector W111, via the front end connector W11 so as to be able to open toward the reference surface 111a.

[0092] The base end holding portion 13 is a component that is arranged in the top surface 112a at the first end side 1a of the base end side of the sliding movement of the sliding portion 12 so as to be immovable in the sliding direction D11. One or more base end holding portions 13 are arranged at the first end side 1a in the arrangement direction D12 while being rotatable around the rotation axis 131 respectively. Here, according to the present embodiment, the base end holding portions 13 are respectively fixedly arranged at the first end side 1a in the plurality of sliding rails 112b. That is, the plurality of sliding portions 12 are configured to be opposite to the plurality of base end holding portions 13 one by one so as to move linearly. Each base end holding portion 13 is a component that holds the rear end connector W12 in the sub-wiring harness W1a one by one so as to be able to open toward the reference surface 111a side. The base end holding portion 13 holds the other end of at least one wire W16, that is, the other end of the number of wires W16 connected to the rear end connector W12, via the rear end connector W12 so as to be able to open toward the reference surface 111a.

[0093] According to the wire harness manufacturing device 1, the front end connectors W11 of the plurality of sub-wiring harnesses W1a are respectively held by the sliding parts 12, and the rear end connectors W12 thereof are respectively held by the base end holding parts 13. Thereafter, by moving the sliding parts 12 holding the front end connectors W11 to positions corresponding to the branching shapes of the wiring harness W1 as the formation target, the plurality of electric wires W16 are stretched between the plurality of base end holding parts 13 and the plurality of sliding parts 12. At this time, Figure 3In the example shown, in the wire harness W1, the number of front-end connectors W11 and the number of rear-end connectors W12 are the same, so that the electric wires W16 are stretched between the plurality of base end holding portions 13 and the plurality of sliding portions W12 having the same number. However, the wire harness as a formation target is of course not limited to Figure 3 The example shown, for example, can be implemented in which there is one rear-end connector and a plurality of front-end connectors. Alternatively, the wiring harness can be constructed to have a plurality of rear-end connectors and a number of front-end connectors that is different from the number of rear-end connectors, that is, more or less than the number of rear-end connectors. In this case, a plurality of sliding portions and one or more base end retaining portions 13 are selected corresponding to the number of front-end connectors and rear-end connectors in the wiring harness as a formation target, and the ends of the wires W16 are retained by each connector. Then, after the sliding portion 12 moves, the plurality of wires W16 are stretched between the one or more base end retaining portions 13 and the plurality of sliding portions 12. Thereafter, wire processing is performed on the wires W16 stretched between the base end retaining portion 13 and the sliding portion 12 by the wire processing portion 14.

[0094] The wire processing section 14 is a mechanism configured to perform wire processing, which includes a process of selectively bundling a plurality of wires W16 stretched between the base end holding section 13 and the slide section 12 to form a branch shape by each slide section 12 moving to a position corresponding to the branch shape. Thus, the wire processing section 14 is set not to contact the wires W16 even when the wires W16 sag due to the position of the slide section 12. The wire processing section 14 includes two robot arms 141 and six processing mechanisms 142.

[0095] As described above, the robot arm 141 is an articulated robot attached to the arm rail 111b provided on the reference surface 111a of the bottom plate portion 111 to move linearly in the sliding direction D11. The robot arm 141 holds a processing mechanism 142 at its front end in a manner that can be replaced with other processing mechanisms 142 to be transported to a work site for wire processing.

[0096] The processing mechanism 142 is a mechanism that is detachably held by the robot arm 141 and transported to the work site of the wire processing to perform the wire processing. In addition, as described above, the processing mechanism 142 stands by at a standby position adjacent to the slide rail 112b that is the moving path of the slide portion 12 in the top surface 112a until it is held by the robot arm 141. According to the present embodiment, the standby positions are set at two positions near a pair of side edges in the rectangular top surface 112a, and three processing mechanisms 142 are set in each standby position 112c. The three processing mechanisms 142 in each standby position 112c are mechanisms corresponding to three types of wire processing performed one by one on the wire W16. That is, the first processing mechanism 142 is a mechanism that performs winding of the tape W131, the second processing mechanism 142 is a mechanism that performs attachment of the corrugated tube W141, and the third processing mechanism 142 is a mechanism that performs attachment of the fixing jig W15. Between the standby positions 112c at two positions, the same type of processing mechanism 142 is set.

[0097] According to the wire processing unit 14, two robot arms 141 correspond to the standby positions 112c at two positions one by one, and each robot arm 141 selectively holds one of the three processing mechanisms 142 corresponding to the processing content to be performed at the corresponding standby position 112c. Thereafter, the robot arm 141 moves on the arm rail 111b to a position corresponding to the work site to transport the processing mechanism 142 to the work site for operation. When performing other operations, the robot arm 141 moves on the arm rail 111b to replace the processing mechanism 142 in the standby position 112c, and transports the replaced processing mechanism 141 to the corresponding work site for operation. In addition, during operation, when the wire W16 droops, the robot arm 141 moves on the arm rail 111b to a position that does not contact the wire W16, and operates while avoiding the wire W16.

[0098] By using the sub-wiring harness supplying vehicle 15, a plurality of sub-wiring harnesses W1a are supplied to the wire harness manufacturing apparatus 1 operating in this manner.

[0099] Figure 4 It is shown from Figure 1 When looking in the direction of arrow V11 Figure 1 A schematic plan view of the secondary wiring harness supply vehicle is shown.

[0100] The auxiliary wiring harness supply vehicle 15 is a vehicle that can move in and out along the reference surface 111a to the supply position P11 between the reference surface 111a, the plurality of slides 12, and the one or more base end holding portions 13 while holding the plurality of auxiliary wiring harnesses W1a. As described above, the device frame 11 generally has a rectangular parallelepiped frame structure with open sides. When supplying the auxiliary wiring harness W1a, as shown in FIG. Figure 1 As shown, the sub-wiring harness supply cart 15 enters the interior of the device frame 11 from the open side surface along the arrangement direction D12 of the arm rail 111b and the slide rail 112b. In addition, at this time, the robot arm 141 retreats from the path of the sub-wiring harness supply cart 15 so as not to hinder the entry of the sub-wiring harness supply cart 15. Then, when the sub-wiring harness supply cart 15 reaches the supply position P11, the front end connector W11 and the rear end connector W12 of the plurality of sub-wiring harnesses W1a being held are delivered from the sub-wiring harness supply cart 15 from the lower side to the sliding portion 12 and the base end holding portion 13. Due to this delivery, the sub-wiring harness W1a is supplied between the sliding portion 12 and the base end holding portion 13.

[0101] The auxiliary wiring harness supply vehicle 15 has a rectangular parallelepiped frame structure, wherein the arrangement direction D12 is the length direction when inserted into the device frame 11, and the auxiliary wiring harness supply vehicle 15 includes a wheeled bottom plate portion 151, a front end retaining top plate portion 152, a rear end retaining top plate portion 153 and a vehicle support column portion 154.

[0102] The wheeled bottom plate portion 151 is a rectangular plate having four wheels 151 a , and when the sub-wiring harness supply cart 15 is inserted, it travels in the arrangement direction D12 on the reference surface 111 a of the bottom plate portion 111 in the device frame 11 .

[0103] The front end holding top plate portion 152 is a rectangular plate to line up the front end connectors W11 of the plurality of sub-wiring harnesses W1a in the arrangement direction D12 and to detachably hold the front end connectors W11 of the plurality of sub-wiring harnesses W1a. On the upper surface of the front end holding top plate portion 152, a plurality of front end connector cups 152a arranged in a line in the arrangement direction D12 are provided to hold the front end connectors W11 respectively. Each front end connector cup 152a is opened on the top side and on the side facing the rear end holding top plate 153, the front end connector W11 enters and exits from the opening at the top side, and the side opening is an extended opening for the wire W16 when holding the connector.

[0104] The rear end holding top plate 153 is a rectangular plate substantially the same as the front end holding top plate portion 152, and on its upper surface, a plurality of rear end connector cups 153a arranged in a row in the arrangement direction D12 are provided. The rear end holding top plate 153 and the front end holding top plate portion 152 are arranged parallel to each other to leave a gap therebetween for the wires W16 to hang down when the connector is held. The wires W16 of the sub-wiring harness W1a extending from the rear end connector cups 153a and the front end connector cups 152a hang down from the gap between the rear end holding top plate 153 and the front end holding top plate portion 152 toward the bottom plate portion 151 of the pulley in a state bent into a U shape.

[0105] The vehicle support pillars 154 are eight support pillars that connect the corners of the rear end holding top plate 153 and the front end holding top plate 152 to the pulley bottom plate 151. The eight vehicle support pillars 154 are configured to support the rear end holding top plate 153 and the front end holding top plate 152 so that they are parallel to each other to leave a gap therebetween for the wire W16 to pass through.

[0106] Here, according to the present embodiment, when the front-end connector W11 and the rear-end connector W12 are delivered from the auxiliary wiring harness supply vehicle 15, the sliding portion 12 moves along the sliding direction D11 to the connector receiving position P12 at the first end side 1a. On the other hand, in the auxiliary wiring harness supply vehicle 15, the front-end connector cup 152a and the rear-end connector cup 153a are arranged as follows. That is, the front-end connector cup 152a is arranged so that the front-end connector W11 at the supply position P11 faces the plurality of sliding portions 12 arranged in a row in the arrangement direction D12 at the connector receiving position P12, respectively. Similarly, the rear-end connector cup 153a is arranged so that the rear-end connector W12 at the supply position P11 faces one or more base end retaining portions 13 arranged in a row in the arrangement direction D12 at the first end side 1a, respectively. As a result, in the stage of inserting the sub harness supply cart 15 up to the supply position P11, the front end connector W11 and the rear end connector W12 are positioned directly below the slide portion 12 and the base end holding portion 13 in the top plate portion 112 in a state of facing each other one-to-one.

[0107] After that, the sub-wiring harness supply vehicle 15 rises at the supply position P11, and presses the front-end connectors W11 and the rear-end connectors W12 of the plurality of sub-wiring harnesses W1a against the slide portion 12 and the base end holding portion 13 one by one, so as to deliver them together. After the sub-wiring harness W1a is supplied by this delivery, the sub-wiring harness supply vehicle 15 descends and retreats to the side from the device frame 11.

[0108] Figure 5A and Figure 5B They are shown in Figures 1 to 4 In the wiring harness manufacturing device shown in the figure, it is a schematic diagram of the state of supplying the sub-wiring harness from the sub-wiring harness supply vehicle and the state of unloading the wiring harness after the manufacturing process is completed. Figure 5A and Figure 5B In the process, the two states of supply and discharge are similar to Figure 4 The side plan view is shown. Figure 5A In FIG. 1 , the state of supplying the sub-wiring harness W1a is shown, and in FIG. Figure 5B , a state where the wire harness W1 is removed is shown.

[0109] In the state when the auxiliary wiring harness W1a is supplied, the front-end connector W11 and the rear-end connector W12 are held by the sliding portion 12 located at the connector receiving position P12 and the base end holding portion fixedly arranged at the first end side 1a. In this state, the electric wire W16 is held in the auxiliary wiring harness supply vehicle 15 while hanging downward in a state bent into a U shape. Thereafter, the sliding portion 12 moves to a position corresponding to the branch shape along the stretching direction D111 away from the base end holding portion 13 to stretch the electric wire W16 in the sliding direction D11, so that the electric wire W16 is stretched between the base end holding portion 13 and the sliding portion 12. The stretched electric wire W16 is subjected to electric wire processing, and the winding of the belt W131, the attachment of the corrugated tube W141 and the attachment of the fixing clamp W15 are performed, thereby manufacturing the wiring harness W1.

[0110] In the unloading state of the wire harness W1 that has been wire-processed by the wire processing portion 14, the plurality of slide portions 12 move along the folding direction D112 to approach the base end holding portion 13, thereby folding the wire W16 in the sliding direction D11. The movement in the folding direction D112 is performed so that the plurality of slide portions 12 are arranged in a row in the arrangement direction D12 of the slide rail 112b at the unloading position P13 at the first end side 1a. According to the present embodiment, the unloading position P13 is the same as the connector receiving position P12 when the secondary wire harness W1a is supplied. Once the state that all the slide portions 12 holding the front-end connector W11 reach the unloading position P13 to be arranged in a row is achieved, each slide portion 12 releases the front-end connector W11 at the unloading position P13. In addition, at this time, the base end holding portion 13 releases the rear-end connector W12. By releasing these connectors, the wire harness W1 that has been processed by the wire processing falls toward the unloading direction D14 due to its own weight to be unloaded.

[0111] Here, based on the description so far, Figure 3 The wire harness W1 shown is shown as an example of a manufacturing target in the wire harness manufacturing apparatus 1. However, the manufacturing target in the wire harness manufacturing apparatus 1 is not limited thereto, and other examples as shown below may be regarded as manufacturing targets.

[0112] Figure 6 is similar to Figure 3 To show as Figure 1 Schematic plan view of another example of a wire harness that is a manufacturing target of the wire harness manufacturing device shown. Figure 6 In, with Figure 3 The same construction components as shown are used in Figure 3 The same reference symbols are used to represent the same structural components, and hereinafter, repeated description of these same structural components is omitted.

[0113] As another example Figure 6The wiring harness W2 shown includes a plurality of front-end connectors W11, a plurality of rear-end connectors W12, and a plurality of tape winding portions W13. In addition, the wiring harness W2 is constructed by combining a plurality of sub-wiring harnesses W2a in which both ends of the electric wire W16 are connected to the front-end connector W11 and the rear-end connector W12. Then, according to the present embodiment, the electric wire 16 bundled into a branch shape by the tape winding portion W13 has a structure in which it is accommodated in two exterior components as a front-end protector W21 and a rear-end protector W22. Either the front-end protector W21 or the rear-end protector W22 is a forked cylindrical exterior component capable of accommodating the electric wire W16 therein from the side intersecting with the length direction, and is composed of a groove-shaped protector body W211 or W221 and a protector cover W212 or W222. In the state where the protector covers W212, W222 are removed, the electric wires W16 are accommodated therein from the slot openings of the protector bodies W211, W221, and thereafter, the protector covers W212, W222 are attached thereto. Here, according to the wire harness manufacturing device 1 in this embodiment, the accommodation of the electric wires W16 to the protector bodies W211, W221 is performed by using the external mounting plate 16 and the electric wire guide 17 described below.

[0114] Fig. 7A and Figure 7B is shown for relative to Figure 6 A schematic diagram of the protector body housing the external mounting plate of the wires is shown, and Figure 8 is shown for use with Fig. 7A and Figure 7B Schematic diagram of the wire guide that receives the wires relative to the protector body together with the external mounting plate shown. Figure 8 In order to make the figure easier to see, the illustration of the sliding portion 12 and the base end holding portion 13 in the top surface 112a is omitted.

[0115] like Fig. 7A As shown, according to the wire harness manufacturing device 1, in the top surface 112a of the top plate portion 112, the wire processing is performed by forming the tape winding portion W13 with respect to the wire W16. At this time, at the outside of the device frame 11, the protector main bodies W211 and W221 are relative to each other as shown in FIG. Figure 7BThe external mounting plate 16 shown in the figure is installed. The external mounting plate 16 is a plate component that can move in and out along the reference surface 111a to the insertion position P14 between the multiple sliding parts 12 and one or more base end retaining parts 13 and the reference surface 111a of the bottom plate part 111. On the upper surface of the external mounting plate 16, the protector bodies W211, W221 are arranged to orient the groove opening as the accommodating side of the wire W16 upward. As described above, during the wire processing of the wire W16 in the top surface 112a, the installation of the protector bodies W211, W221 to the external mounting plate 16 is performed manually by an operator, an operating robot (not shown), etc. at the outside of the device frame 11. The external mounting plate 16 with the protector bodies W211, W221 installed is inserted into the above-mentioned insertion position P14 in the device frame 11. At the insertion position P14, the slot openings of the protector bodies W211 and W221 on the external mounting plate 16 are in a state facing the wires W16 that have become branched after wire processing. In this state, when the slide portion 12 and the base end holding portion 13 release the front connector W11 and the rear connector W12, the wires W16 are unloaded downward and fall toward the external mounting plate 16. At this time, the wire guide portion 17 is used to accommodate the wires W16 from the slot openings of the protector bodies W211 and W221.

[0116] The wire guide 17 is a component configured to guide the wire W16 so as to accommodate the wire W16 in the protector body W211, W221, wherein the wire guide 17 is arranged to be detachable between the external mounting plate 16 and the sliding portion 12 and the base end retaining portion 13 moved to a position corresponding to the branch shape. According to the present embodiment, the wire guide 17 is a plurality of pairs of rod-shaped components as follows. Each wire guide 17 connects the vicinity of the branch point of the wire W16 in the top surface 112a provided with the sliding portion 12 and the base end retaining portion 13 with the vicinity of the end of the protector body W211, W221 in the external mounting plate 16 in the up-down direction D13. One end of each wire guide 17 is fixed in the top surface 112a, and the other end is fixed in the external mounting plate 16. When the electric wires W16 are discharged to fall, the electric wires W16 passing between each pair of electric wire guides 17 are guided to the slot openings of the protector bodies W211, W221 while maintaining the branched shape, and are then accommodated therein. Thereafter, the electric wire guides 17 are removed, and the external mounting plate 16 is taken out to the outside of the device frame 11 together with the undischarged electric wires W16. Then, at the outside, the protector covers W212, W222 are attached to the protector bodies W211, W221, and as Figure 6 As shown, the wire harness W2 having the electric wires W16 with the protectors has been completed.

[0117] According to the above-mentioned wire harness manufacturing device 1, the wire harnesses W1 and W2 can be automatically manufactured by performing a wire processing including stretching the wire W16 between the base end holding portion 13 and the sliding portion 12 to form a branch. At this time, for the wire W16 in the manufacturing process, both ends thereof are in a state of being held by the sliding portion 12 and the base end holding portion 13 at the top height H11 from the reference surface 111a. Depending on the position of the sliding portion 12, however, in this case, the wire W16 may become loose, but in this case, the wire W16 will hang down due to its own weight, thereby preventing the wire W16 from being caught by the sliding portion 12 and the base end holding portion 13 at the top height H11. In addition, the wire processing portion 14 that performs the wire processing on the wire W16 is set not to contact the wire hanging downward, thereby also preventing the wire W16 from being caught by the wire processing portion 14. Thus, according to the wire harness manufacturing device 1 of this embodiment, the wire harnesses W1 and W2 can be automatically manufactured while preventing the wire W16 in the manufacturing process from being caught.

[0118] Here, according to the present embodiment, the sub-wiring harness W1a is supplied between the sliding portion 12 and the base end holding portion 13. Then, the sliding portion 12 and the base end holding portion 13 hold both ends of the electric wire W16 via the front end connector W11 and the rear end connector W12 in the sub-wiring harness W1a. According to this configuration, the electric wire W16 is supplied between the sliding portion 12 and the base end holding portion 13 in the state of the sub-wiring harness W1a, and at this time, the delivery of the front end connector W11 and the rear end connector W12 is performed from below the side of the reference surface 111a. As a result, the supply of the sub-wiring harness W1a as a preliminary stage of the manufacturing of the wiring harness is performed in a state where the electric wire W16 is suspended downward, so that it can be performed in a state where the electric wire W16 is prevented from being caught by the sliding portion 12, the base end holding portion 13 and the wire processing portion 14.

[0119] Furthermore, according to the present embodiment, a sub-wiring harness supply vehicle 15 is provided in the wiring harness manufacturing device 1. The sub-wiring harness supply vehicle 15 is capable of entering and exiting the supply position P11 while holding a plurality of sub-wiring harnesses W1a, and is capable of entering the supply position P11 to supply a plurality of sub-wiring harnesses W1a. According to this structure, by making the sub-wiring harness supply vehicle 15 hold a plurality of sub-wiring harnesses W1a and enter the supply position P11, it is possible to make the supply more efficient compared to the case where a plurality of sub-wiring harnesses W1a are supplied separately.

[0120] Furthermore, according to the present embodiment, when the front-end connector W11 is received from the auxiliary wiring harness supply vehicle 15, the sliding portion 12 moves to the connector receiving position P12 at the first end side 1a. At this time, the sliding portion 12 is arranged in a row in the arrangement direction D12 at the connector receiving position P12, and the base end retaining portion 13 is arranged in a row in the arrangement direction D12 at the first end side 1a. When the auxiliary wiring harness supply vehicle 15 is inserted into the supply position P11, the front-end connector W11 and the rear-end connector W12 are detachably retained so as to be arranged relative to these sliding portions 12 and the base end retaining portion 13 in a one-to-one correspondence. According to this configuration, the front-end connector W11 and the rear-end connector W12 held by the auxiliary wiring harness supply vehicle 15 as the supply target are arranged in a one-to-one correspondence relative to the sliding portion 12 and the base end retaining portion 13 as the supply destination, thereby facilitating delivery.

[0121] Furthermore, according to the present embodiment, when the auxiliary wiring harness supply vehicle 15 enters the supply position P11, the auxiliary wiring harness supply vehicle 15 can rise. Due to the rise, the auxiliary wiring harness supply vehicle 15 presses the front-end connector W11 and the rear-end connector W12 against the sliding portion 12 at the connector receiving position P12 and the base end retaining portion 13 at the first end side 1a to deliver them together. According to this configuration, due to the rise of the auxiliary wiring harness supply vehicle 15, the front-end connector W11 and the rear-end connector W12 are delivered together, so that the operation time related to the supply of the auxiliary wiring harness W1a can be significantly reduced.

[0122] Furthermore, according to the present embodiment, the sliding portion 12 and the base end holding portion 13 release one end and the other end of the electric wire W16 that has been processed in the electric wire processing portion 14 to drop, and the electric wire W16 is discharged to the reference surface 111a side. According to this configuration, the discharge of the electric wire W16 that has been processed in the electric wire processing portion 14 can be performed by only releasing the end portions in the sliding portion 12 and the base end holding portion 13, and there is no need to provide a special clamp or the like. As a result, the operation time and the device cost associated with the discharge operation of the processed electric wire W16 can be reduced.

[0123] Furthermore, according to the present embodiment, after processing at the wire processing portion 14, the sliding portion 12 moves to line up in the arrangement direction D12 at the discharge position P13 at the first end side 1a, and releases one end side of the wire W16 at the discharge position P13. According to this configuration, before discharge, the sliding portion 12 approaches the base end retaining portion 13 at the first end side 1a to line up at the discharge position P13. As a result, in a state where the front end connector W11 is aligned together with the rear end connector W12, the wire W16 as the discharge target is folded and hangs downward. Due to this drooping of the wire W16, during discharge of the wire W16, it is possible to discharge while preventing the wire W16 from being caught by structures such as the sliding portion 12, the base end retaining portion 13, etc. on the top surface 112a.

[0124] Furthermore, according to the present embodiment, the wire harness manufacturing device 1 includes an external mounting plate 16 and an electric wire guide 17. The external mounting plate 16 is a component that enters the insertion position P14 in a state where the protector bodies W211 and W221 constituting the front protector W21 and the rear protector W22 are mounted on the upper surface as an exterior component in a manner that the accommodation side of the electric wire W16 faces upward. The electric wire guide 17 is a component for guiding the electric wire W16 that falls due to unloading to accommodate the electric wire 16 in the protector bodies W211 and W221. According to this configuration, the protector bodies W211 and W221 are attached to the electric wire W16 by setting the protector bodies W211 and W221 on the upper surface of the external mounting plate 16, inserting the external mounting plate 16, and guiding the falling electric wire by the electric wire guide 17. Among these steps, the step performed by the operator, the robot arm, etc. is to set the protector bodies W211 and W221 on the upper surface of the external mounting plate 16. This operation is much more efficient than directly attaching the protector bodies W211, W221 to the wires W16 stretched at a predetermined height. Thereafter, the external mounting plate 16 in which the protector bodies W211, W221 are arranged is inserted, and the unloading of the wires W16 through the falling of the wires W16 is performed. During the unloading process, the wires W16 are automatically accommodated inside the protector bodies W211, W221 through the guidance of the wire guide 17. In this way, according to the above-mentioned structure, it is possible to minimize the operations performed by the operator, the robot arm, etc. to the necessary minimum limit for setting the protector bodies W211, W221 to the upper surface of the external mounting plate 16, thereby improving operability.

[0125] Furthermore, according to the present embodiment, the wire processing section 14 includes a robot arm 141 and a processing mechanism 142. The robot arm 141 is arranged at a position where it does not contact the wire W16 even if the wire W16 droops. The processing mechanism 142 is a mechanism that is detachably held by the robot arm 141 to be transported to a work site for wire processing to perform wire processing. The processing mechanism 142 stands by at a standby position 112c adjacent to the moving route of the sliding portion 12 on the top surface 112a at the top height H11 until it is held by the robot arm 141. According to this configuration, the robot arm 141 is set at a position where it does not contact the wire W16, and the processing mechanism 142 stands by in the standby position 112c at the top height H11 before being held by the robot arm 141. As a result, it is possible to effectively prevent the wire W16 in a drooping state from being caught by either the robot arm 141 or the processing mechanism 142.

[0126] Furthermore, according to the present embodiment, in the standby position 112c, various types of processing mechanisms having different processing contents stand by in the standby position 112c. The robot arm 141 selectively holds one processing mechanism 142 from these various types of processing mechanisms 142 according to the processing content to be performed. According to this configuration, by arranging various types of processing mechanisms 142 in the standby position 112c at the top height H11, it is possible to cope with various wire processing while effectively preventing the wire W16 from being caught.

[0127] Note that the above-described embodiment merely shows a typical form of the wire harness manufacturing apparatus. The wire harness manufacturing apparatus is not limited thereto, and various modifications can be implemented.

[0128] For example, according to the above-described embodiment, as an example of the wire harness of the manufacturing target, the wire harness W1 installed and routed in the vehicle is exemplified. However, the wire harness is not limited thereto, and it may be a wire harness for use outside the vehicle.

[0129] Furthermore, according to the above-described embodiment, as an example of a wiring harness of a manufacturing target, Figure 3 , Figure 6 However, the wire harness is not limited thereto, and as long as it has a branched shape, the specific number of branches, the presence or absence of an exterior component, the type, etc. are not critical.

[0130] Furthermore, according to the above-described embodiment, as an example of a harness manufacturing device, a harness manufacturing device 1 is illustrated in which a sub-harness W1a is supplied between a sliding portion 12 and a base end holding portion 13. The sliding portion 12 and the base end holding portion 13 shown in this example hold both ends of the wire W16 via the front-end connector W11 and the rear-end connector W12 in the sub-harness W1a. However, the harness manufacturing device is not limited thereto, and the wires drawn from the wire reel may be supplied between the sliding portion and the base end holding portion instead of the sub-harness, and the sliding portion and the bottom end holding portion may directly hold the ends of the wires. In this case, a mechanism for connecting the ends of the wires held by the various parts to the connectors of the harness may be additionally provided. However, as described above, according to the supply of the wires via the front-end connector W11 and the rear-end connector W12 of the sub-harness W1a, it is possible to prevent the wire W16 from being stuck in the supply stage before the harness manufacturing.

[0131] Furthermore, according to the above-described embodiment, as an example of a wire harness manufacturing device, a wire harness manufacturing device 1 including a sub-wiring harness supply vehicle 15 for holding and supplying a plurality of sub-wiring harnesses W1a is described. However, the wire harness manufacturing device is not limited thereto. In the wire harness manufacturing device, for example, a plurality of sub-wiring harnesses may be supplied individually by an operator, a robot arm, or the like. However, as described above, by using the sub-wiring harness supply vehicle 15, a plurality of sub-wiring harnesses W1a can be efficiently provided.

[0132] Furthermore, according to the above-described embodiment, as an example of a wire harness manufacturing device, a wire harness manufacturing device 1 is described, in which, when receiving the front-end connector W11, the sliding portion 12 moves to the connector receiving position P12 to be aligned with the base end retaining portion 13. Then, according to the wire harness manufacturing device 1, the sub-wiring harness supply vehicle 15 detachably holds the front-end connector W11 and the rear-end connector W12 in an arrangement state to face the sliding portion 12 and the base end retaining portion 13 in a one-to-one correspondence at the supply position P11. However, the wire harness manufacturing device is not limited to this. For example, the wire harness manufacturing device may be constructed so that the arrangement of the sliding portion and the base end retaining portion and the connector arrangement in the sub-wiring harness supply vehicle at the supply position are not particularly corresponding. However, as described above, by making these arrangements one-to-one correspondence, it is possible to facilitate the delivery of the front-end connector W11 and the rear-end connector W12 to the sliding portion 12 and the base end retaining portion 13.

[0133] Furthermore, according to the above-described embodiment, as an example of a sub-wiring harness supply vehicle, the sub-wiring harness supply vehicle 15 is described which rises when entering the supply position P11 and presses the front-end connector W11 and the rear-end connector W12 against the delivery destination to deliver them together. However, the sub-wiring harness supply vehicle is not limited thereto, and it may be constructed so that the connector supply after entering the supply position P11 is performed separately by an operator, a robot arm, etc. However, as described above, according to the construction in which the connectors are pressed against the supply destination to deliver them together due to the rise of the sub-wiring harness supply vehicle 15, the supply time of the sub-wiring harness W1a can be significantly reduced.

[0134] Furthermore, according to the above-described embodiment, as an example of a wire harness manufacturing device, the wire harness manufacturing device 1 is described, which is configured to discharge the electric wire W16 by causing the electric wire to fall due to the release of the connector at the sliding portion 12 and the base end holding portion 13. However, the wire harness manufacturing device is not limited thereto, and may be configured to discharge the electric wire using a discharge jig. However, as described above, according to the configuration of discharging the electric wire W16 by releasing the connector to cause the electric wire to fall, it is possible to reduce the operation time and device cost associated with the discharge operation of the processed electric wire W16.

[0135] Furthermore, according to the above-described embodiment, as an example of a wire harness manufacturing device, the wire harness manufacturing device 1 is described in which the slide portion 12 moves to the unloading position P13 after the processing at the wire processing portion 14 to perform the release of the wire W16. However, the wire harness manufacturing device is not limited thereto, and, for example, it may be configured so that the slide portion does not move from the position at the end of the wire processing to release the wire W16. However, as described above, by moving the slide portion 12 to the unloading position P13 to release the wire W16 in a state where the wire W16 is suspended downward, during the unloading of the wire W16, it is possible to perform the unloading while preventing the wire W16 from being caught by the structure on the top surface 112a.

[0136] Furthermore, according to the above-described embodiment, as an example of a wire harness manufacturing device, a wire harness manufacturing device 1 including an external mounting plate 16 and a wire guide 17 is described. However, the wire harness manufacturing device is not limited thereto, and it may be configured such that an exterior component is directly attached to the wire stretched at a predetermined height by an operator, a robot arm, or the like. However, as described above, by providing the external mounting plate 16 and the wire guide 17, it is possible to improve its operability while minimizing the necessity of operations by the operator, the robot arm, or the like. Furthermore, according to the above-described embodiment, as an example of an exterior component, a front end protector W21 and a rear end protector W22 including a protector body W211, W221 and a protector cover W212, W222 are described. However, the exterior component is not limited thereto, and the specific form of the component is not limited as long as it has a cylindrical shape and can accommodate the wire inside from the side intersecting the length direction. Examples of such exterior components include corrugated tubes and twisted tubes that can accommodate wires through slits on the circumferential surface.

[0137] Furthermore, according to the above-described embodiment, as an example of a wire processing unit, a wire processing unit 14 is described, which includes a robot arm 141 that does not contact the wire W16 hanging down and a processing mechanism 142 that stands by at a standby position 112c until it is held by the robot arm 141. However, the wire processing unit is not limited thereto, and the specific mechanism configuration is not limited thereto, and for example, it may be configured as a robot arm having a processing mechanism as an integrated mechanism, etc., as long as it is set in a manner that does not contact the wire. However, as described above, according to the wire processing unit 14 including the robot arm 141 and the processing mechanism 142, it is possible to effectively prevent the wire W16 in a hanging down state from being stuck.

[0138] Furthermore, according to the above-described embodiment, as an example of a processing mechanism and an example of a robot arm, various types of processing mechanisms 142 that stand by at the standby position 112c and the robot arm 141 that is configured to selectively hold one processing mechanism 142 according to the processing content are described. However, the processing mechanism and the robot arm are not limited thereto, and may be configured such that only one processing mechanism stands by at the standby position, and the robot arm holds the one processing mechanism. However, as described above, according to the configuration in which the robot arm 141 selectively holds one processing mechanism 142 among various types of processing mechanisms 142 at the standby position 112c, it is possible to cope with various wire processing while effectively preventing the wire W16 from being caught.
