BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the auxiliary device for assembling the wire harness and the method for manufacturing the wire harness according to the embodiment will be described.

[0028] Here, the basic configuration of the wire harness assembly auxiliary device and the method of manufacturing the wire harness will be described, and then a more specific example of the wire harness assembly auxiliary device will be described.

Two examples will be described.

[0029] <1. Basic configuration of wire harness assembly auxiliary device and wire harness manufacturing method> First, the wire harness to be manufactured will be described. Fig. 1 is a diagram showing an example of the wiring pattern of the wire harness.

[0030] The wire harness 10 is used as a wiring material in a vehicle, and is assembled in a predetermined wiring form in which a three-dimensional wiring form in the vehicle is two-dimensionally developed. The wire harness 10 is configured by bundling a plurality of electric wires together with a tape, a binding tool, or the like at an appropriate place while collecting and branching along a predetermined wiring form. Further, on the middle part of the wire harness 10, exterior parts such as a corrugated tube for protecting the electric wire, a grommet for waterproofing, and a fixing tool for fixing the wire harness are attached. In addition, a connector, a crimp terminal, or the like is attached to the end of each electric wire, and each electric wire is electrically connected to a predetermined on-vehicle electric product via the connector crimp terminal.

In addition, the wire harness 10 has a main line portion 12 and a branch line portion 14. The trunk portion 12 is a portion in which the electric wires are bundled most, and here, the trunk portion 12 is arranged so as to extend along the substantially left-right direction of the wire harness 10. Further, the branch line portion 14 is disposed so as to extend outward from the end or middle of the main line portion 12.

[0032] Such a wire harness 10 is manufactured by combining a plurality of temporary joints 16 (see FIGS. 2 and 3). The temporary connection 16 is composed of one or a plurality of electric wires with connectors and terminals attached to the ends. Such a temporary connection 16 is manufactured by a temporary wire harness assembly work table apparatus or the like located at a different location from the wire harness assembly work table apparatus 30 (see FIG. 3) for assembling the wire harness 10. Then, the temporary binding 16 is transported to the wire harness assembly work table device 30 and is appropriately bound by the wire harness assembly work table device 30 to be manufactured in the form of the wire harness 10.

A method for manufacturing the wire harness 10 will be described. 2 and 3 are diagrams showing each process of manufacturing the wire harness, FIG. 2 is a diagram showing a state in which the end of each temporary connection is held by a temporary holder, and FIG. 3 is a temporary diagram. It is a figure which shows the state which arrange | positions a knot on the main work surface. In addition, in each figure, the connector, the terminal, etc. of the temporary connection part are abbreviate | omitted.

[0034] The method of manufacturing the wire harness 10 includes a step of holding the end portions of the temporary connections 16 to the temporary connection holder 20, and a main operation of the wire harness assembly work table apparatus 30 by fixing the end portions of the temporary connections 16 to each other. And a process of disposing on the surface 31. Of these, the former process is a temporary wire harness assembly. This is related to the process of transporting the temporary assembly 16 manufactured by the standing work table apparatus etc. to the wire harness assembly work table apparatus 30. The latter process uses the transported temporary structures 16 to perform the wire harness 10 It relates to the manufacturing process.

[0035] Describing for each step, the step of holding the end of each temporary connection 16 on the temporary connection holder 20 is performed by connecting the end of each temporary connection 16 to the wire harness 10 as shown in FIG. This is the process of holding the temporary holding fixture 20 for each of the groups G1 to G7 (see FIG. 1) divided according to the position in the form. In this manner, the end portions of the temporary connections 16 are held in the temporary connection holder 20 separately for the Gnoles G1 to G7, so that the end portions of the temporary connections 16 are prevented from being entangled and damaged.

More specifically, in this step, it is premised that the ends of the respective fabrics 16 in the predetermined wiring form are divided into a plurality of groups G1 to G7 (see FIG. 1). ). The main criteria for the gnope division are the gnole divisions according to the positions of the end portions of the temporary bonds 16 in the predetermined wiring form of the wire harness 10 in the wire harness assembly work table apparatus 30. Preferably, as a secondary reference, the main line portion 12 may be divided above and below, or may be divided into a plurality along the extending direction of the main line portion 12.

[0037] From another viewpoint, such grouping is directed from one side of the wire harness 10 to the other side, more specifically, from one end along the main line portion 12. It is possible to grasp that the end portions of each temporary connection 16 are divided into gnorapes so that the end portions of each temporary connection 16 can be sequentially arranged on the wire harness assembly work table device 30 toward the end portion.

[0038] Here, the end of each temporary connection 16 is divided into gnoles Gl, G2, G3, G4, G5, G6, and G7 from one end side of the trunk line portion 12 to the other end side.

[0039] Then, on the premise of the above-described gnoleop division, each end portion of each temporary connection 16 manufactured individually is held in the temporary connection holder 20 for each of the groups G1 to G7 to which it belongs.

[0040] The temporary holding tool 20 has a plurality of temporary connection end holding parts 22 for holding the end of each temporary connection 16. Each temporary connection end holding portion 22 is configured to hold the end of each temporary connection 16 for each of the groups G1 to G7, and is formed in a substantially U-shaped slit groove shape in which an electric wire can be inserted. Yes. In addition, each temporary connection end holding portion 22 is provided with a linear interval. Then, by holding the end portions of one or a plurality of temporary connections 16 in each temporary connection end portion holding section 22, the end portions of each temporary connection 16 are held separately for the above-mentioned gnolees G1 to G7. Here, each group G1 to G7 are held in such a positional relationship that they are arranged in the order in which they are directed from one end side to the other end side of the trunk portion 12. A plurality of such temporary holding tools 20 are prepared to hold each temporary connection 16 continuously manufactured for a plurality of wire harnesses 10 for each target wire harness 10. Each temporary connection 16 held by one temporary connection holder 20 may be all temporary connections 16 constituting the wire harness 10 or a part of the temporary connections 16.

[0041] Then, in a state where the plurality of temporary bonds 16 are held using the temporary holder 20, the temporary wire harness assembly work table apparatus to the wire harness assembly work table apparatus together with the temporary holder 20 Delivered to 30.

[0042] In the next step, as shown in Fig. 3, the temporary holding fixture 20 is moved along the main work surface 31 on which the wire harness 10 is assembled, and the end of each temporary connection 16 is moved to the main work. Arrange on surface 31.

That is, the wire harness assembling work table device 30 is configured to be able to hold each temporary connection 16 along the predetermined wiring form of the wire harness 10. Here, the wire harness assembly work table apparatus 30 has a work plate 32 for assembling the wire harness 10. The upper surface of the work plate 32 is a main work surface 31 for assembling the wire harness 10. The main work surface 31 is formed in a substantially rectangular shape that is long in one direction, and is arranged such that its longitudinal direction follows a substantially horizontal posture. In addition, a holder (not shown) for the wire harness 10 such as a U-shaped jig is erected on the main work surface 31, and the trunk portion 12 extends along the longitudinal direction of the main work surface 31 (that is, The wire harness 10 can be assembled on the main work surface 31 in such a posture as to be along a substantially horizontal posture. The attitude along the longitudinal direction (substantially horizontal position) of the main work surface 31 means that the main line portion 12 is an attitude along the longitudinal direction (substantially horizontal position) of the main work surface 31 as a whole. This includes the case where the main work surface 31 is partially inclined with respect to the longitudinal direction (substantially horizontal posture). Note that the wire harness 10 may be assembled on a work frame in which rod-like frames that are not necessarily assembled on the work plate 32 are assembled two-dimensionally or three-dimensionally. In this case, the surface on which the main portion such as the trunk portion 12 of the wire harness 10 is disposed is the main work surface.

[0044] The wire harness assembling work table apparatus 30 includes a temporary holding fixture mounting portion 40 and a temporary attachment tool 40. A tie holder moving support 50 is provided.

[0045] The temporary holding fixture mounting portion 40 is configured to be able to attach the temporary holding fixture 20 detachably. As a configuration for detachably attaching the temporary holder 20, a configuration using magnetic force, a configuration using a fitting structure, an engagement structure, or the like is employed.

[0046] Further, the temporary holding tool movement support section 50 is configured to support the temporary holding tool mounting section 40 on the wire harness assembly work table apparatus 30 so as to be movable. Such a virtual holder moving support part 50 is constituted by a guide rail structure or the like.

[0047] Then, by attaching the temporary holder 20 to the temporary holder holder 40, the temporary holder 20 is supported on the main work surface 31 by the temporary holder moving support 50. The Here, the temporary holder 20 is in a posture substantially perpendicular to the extending direction (ie, substantially horizontal posture) of the trunk portion 12 and along the extending direction (ie, substantially horizontal direction) of the trunk portion 12. Supported movably. The temporary holder 20 and the temporary holder holder 40 are supported so as to move at a height above the main work surface 31 so as not to interfere with the holder of the wire harness 10 and the like.

[0048] The auxiliary device for assembling the wire harness includes the temporary holding fixture 20, the wire harness assembling work table device 30, the temporary holding fixture mounting portion 40, and the temporary holding fixture moving support portion 50. is there.

[0049] In manufacturing the wire harness 10 by arranging each temporary connection 16 on the wire harness assembly work table apparatus 30, first, the temporary connection holder 20 is attached to the temporary attachment holder mounting portion 40. Thus, it is disposed on one end side in the moving direction A by the temporary holder moving support portion 50, here, on one end side of the trunk portion 12 (left end side in FIG. 3, hereinafter referred to as the movement start end side).

[0050] The temporary holding tool 20 is continuously or intermittently moved to the other end side in the moving direction A (the other end side of the trunk portion 12 (the right end side in FIG. 3, hereinafter referred to as the movement end end side). First, an area corresponding to the group G1 that is present at the position closest to the movement start end along the moving direction A of the temporary holding holder 20 is disposed in the vicinity of the temporary holding holder 20. Therefore, the end of the temporary connection 16 corresponding to the Gnolepe G1 is detached from the temporary connection holder 20, and is disposed and fixed at a predetermined position on the work plate 32. The temporary connection holder 20 Is moved further toward the end of movement, then it corresponds to group G2 that is located at a position closer to the end of movement. The region is arranged near the temporary holder 20. Therefore, the end of the temporary connection 16 corresponding to the group G2 is removed from the temporary connection holder 20, and is disposed and fixed at a predetermined position on the work plate 32. Hereinafter, in the same manner, while moving the temporary holder 20 along the moving direction A toward the end of movement, the ends of the temporary holders 16 corresponding to the Gnoles G3 to G7 are sequentially attached to the temporary holder. Remove from 20 and place and fix in place on work plate 32.

That is, when the temporary holder 20 is moved continuously or intermittently toward the movement end, the regions corresponding to the above-mentioned gnolees G1 to G7 are directed from one end of the main line portion 12 to the other end. In this order, they are arranged in the vicinity of the temporary holder 20 one after another. Therefore, as the temporary holder 20 is moved, the ends of the temporary members 16 belonging to the Gnolepes G1 to G7 arranged in the vicinity of the temporary holder 20 are sequentially attached to the temporary holder 20. And then placed and fixed in place on the work plate 32. At this time, the end of each temporary connection 16 is held for each of the above groups G1 to G7, and each group G1 to G7 is positioned so as to be arranged in order of force from one end side to the other end side of the temporary connection holder 20. Because of this, the end of each temporary connection 16 is removed sequentially from the temporary connection end holding part 22 on one end side of the temporary holding holder 20 toward the temporary connection end holding part 22 on the other end side. I'll do it.

[0052] When all the temporary bonds 16 are arranged as the constituent wiring members of the wire harness 10 on the main work surface 31, the wire harness 10 is manufactured. At this time, the wire harness 10 may be manufactured by appropriately adding another temporary bonding 16.

The temporary holder 20 from which all the temporary bonds 16 have been removed is removed from the temporary holder holder 40. The removed temporary holding tool 20 is returned to the temporary wire harness assembly work table device or the like, and the additional temporary attachment 16 of the wire harness 10 leaves or the temporary attachment 16 for another wire harness 10 is held. And used again.

[0054] According to the auxiliary device for assembling the wire harness configured as described above, the temporary attachment holder 20 having the plurality of temporary connection end holding portions 22 for holding the end portions of the temporary connections 16 is provided. In the state where the end of each temporary connection 16 is held by each temporary connection end holding section 22, the temporary connection 16 can be transported and handled. Therefore, it is possible to prevent entanglement, scratches, etc. of each temporary assembly 16. In addition, the temporary holding holder 20 is attached to the temporary holding holder attaching portion 40, and the main working surface 31 of the wire harness assembly work table device 30 together with the temporary holding holder attaching portion 40. Since the temporary holder 20 is moved, the end portion of the temporary holder 16 held by the temporary holder 20 is attached to the mounting position of each group G1 to G7 on the main work surface 31. It can arrange | position sequentially in the vicinity of an installation. Accordingly, the wire harness 10 can be easily manufactured by sequentially arranging the end portions of the temporary bond 16 held by the temporary holder 20 on the main work surface 31 of the wire harness assembly workbench device 30. Can do. In addition, since such a temporary holder 20 does not need to adopt a stretchable configuration, it is possible to easily simplify the configuration.

[0055] Further, even when paying attention to the manufacturing method of the wire harness 10, the end portions of the temporary bonds 16 are divided into groups Gl to G7 divided according to the positions of the wire harnesses 10 in a predetermined wiring form. Then, the temporary holding tool 20 is held, and the temporary holding tool 20 is moved along the main work surface 31, and the end of each temporary connection 16 is disposed on the main work surface 31. For this reason, it is possible to deliver the temporary connection 16 with the temporary holder 20 having a relatively simple configuration while preventing the temporary connection 16 from being twisted. Further, while moving the temporary holder 20 according to the position of the Gnolepe G1 to G7, the end of each temporary unit 16 can be arranged on the main work surface 31 for each Gnolepe G1 to G7. The wire harness 10 can be easily manufactured from the temporary assembly 16.

The wire harness assembly work table apparatus 130 has a work plate 132 having the same configuration as the work plate 32 described above. On the main work surface 131 of the work plate 132, the wire harness 10 to be manufactured is held in a posture in which the main line portion 12 is aligned in a substantially horizontal direction (longitudinal direction of the main work surface 131). It has been done.

[0068] Further, the temporary attachment holder mounting portion 140 causes the temporary attachment holder 120 to be substantially parallel to the main work surface 131 and substantially in the extending direction (substantially horizontal direction) of the main line portion 12. It can be held in a vertical position. Further, the temporary holder holding support 150 is configured to support the temporary holder holder 140 so as to be movable in a substantially horizontal direction.

[0069] More specifically, the temporary holding fixture attaching portion 140 is a rod-like member formed of a metal or the like that can be attracted by a magnet. In addition, the temporary holding fixture attaching portion 140 may have a configuration in which a metal plate or the like that can be attracted by a magnet is attached to a rod-like member formed of resin or the like. Then, the temporary holding holder 120 is mounted in a posture in which the longitudinal direction thereof is along the longitudinal direction of the temporary holding holder mounting portion 140 and is directed away from the main work surface 131. It can be detachably attached to part 140 by magnetic force. In addition, here, the end portion of the temporary connection 16 held by the temporary connection holder 120 is directed to the movement end end side in the movement direction A, and the intermediate portion of the temporary connection 16 is the movement start end in the movement direction A. The temporary holder 120 is attached to the temporary holder attachment part 140 in such a posture as to face the side.

[0070] Temporary holder moving support 150 is attached to guide rail member 152 disposed above work plate 132 in a substantially horizontal direction, and is reciprocally attached to guide rail member 152. And a movable member 154. From the viewpoint of reducing the burden on the operator, it is preferable that the movable member 154 can be moved with a pushing force of about 5N, for example. The temporary holding fixture mounting portion 140 is disposed so that its longitudinal direction is substantially parallel to the main work surface 131 and substantially perpendicular to the extending direction (substantially horizontal direction) of the main trunk portion 12. Attitude and support It is.

[0071] Thereby, the temporary holding holder 120 attached to the temporary holding holder attaching portion 140 is supported to be movable along the substantially horizontal direction in the above posture.

[0072] The auxiliary device for assembling the wire harness according to the first example includes the wire harness assembling work table device 130, the temporary holding fixture attaching portion 140, and the temporary holding fixture moving support portion 15 as described above.

It is configured with 0.

[0073] Further, the auxiliary device for assembling the wire harness has each temporary binding held by the temporary holder 120.

Interference prevention members 160, 162, and 164 are provided to prevent the 16 hanging portions from interfering with the wire harness assembly work table device 130.

Here, three interference preventing members 160, 162, 164 are provided.

The interference prevention member 160 is a substantially rectangular plate-like member formed of resin or the like, and has a length dimension that is substantially the same as the length dimension of the temporary holding holder 120. The interference prevention member 160 is attached in a substantially parallel posture with the main work surface 131 along the side of the temporary attachment holder attachment portion 140 on the movement end end side in the movement direction A (the right side portion in FIG. 8). It has been.

[0076] Even when the end portion of the temporary connection 16, for example, the connector end portion, the terminal end portion, or the like largely extends from the temporary connection holder 120 to the movement end end side in the movement direction A, Guide the end of the temporary connection 16 to support it from below so that it does not interfere with the members on the main work surface 131 side.

[0077] Further, the interference preventing member 162 is a substantially right triangular plate member formed of resin or the like.

Of the two sides sandwiching the right apex, one side 162a has substantially the same length as the length of the temporary holder 120. The interference prevention member 162 is attached along the side portion on the movement start end side in the movement direction A (the left side portion in FIG. 8) of the temporary holding fixture attachment portion 140. In this mounted state, the interference preventing member 162 has a side 162a having a length substantially the same as the length of the temporary holder 120 out of the two sides sandwiching the right-angled vertex. And the other side 162b is disposed so as to extend from the free end of the temporary holder attaching portion 140 to the movement start end side along the movement direction A, and The posture is substantially parallel to the main work surface 131.

[0078] Then, an intermediate portion of the temporary fastening 16 that hangs down from the temporary fastening holder 120 so as to draw a substantially U shape (see FIG. 8) is supported from below while being guided toward the free end of the temporary holder mounting portion 140 so as not to interfere with members on the main work surface 131 side.

[0079] Further, the interference preventing member 164 is a substantially rod-like member formed of metal or resin, and the length dimension of the side 162b extending along the moving direction A among the sides of the interference preventing member 162 is as follows. Is also formed in a large length dimension. The interference preventing member 164 is attached to the free end of the temporary holder attaching portion 140 so as to extend from the free end along the moving direction A to the movement start end side.

[0080] Even if the intermediate portion (see Fig. 8) of the temporary fastening 16 that drastically drops so as to draw a substantially U-shape from the temporary attachment holder 120 protrudes from the interference preventing member 162, the temporary fastening The middle part of 16 is hung on the interference prevention member 164 to guide the member so as not to interfere with the member on the main work surface 131 side.

[0081] With the wire harness assembling auxiliary device configured as described above, the wire harness 10 can be manufactured by the same procedure as described above.

Accordingly, as described above, it is possible to easily manufacture the wire harness 10 from the temporary connection 16 by delivering the temporary connection 16 with a relatively simple configuration while preventing the temporary connection 16 from being entangled. it can.

[0083] In particular, the temporary holding fixture mounting portion 140 is configured so that the temporary holding fixture 120 is substantially parallel to the main work surface 131 and substantially perpendicular to the extending direction (substantially horizontal direction) of the main line portion 12. The temporary attachment holder moving support portion 150 can be attached in a posture, and supports the temporary attachment holder attachment portion 140 so as to be movable in a substantially horizontal direction. For this reason, the end portion of the temporary connection 16, particularly the end portion of the temporary connection 16 held at the intermediate portion in the longitudinal direction of the temporary attachment holder 120, is located at the intermediate portion in the vertical direction of the wire harness 10 on the main work surface 131. It can be arranged. Accordingly, there is an advantage that when the end portion of the temporary connection 16 held by the temporary connection holder 120 is disposed at a predetermined position on the main work surface 131, the amount of movement can be reduced.

[0084] Further, interference preventing members 160, 162, and 164 are provided for guiding the suspended portions of the temporary members 16 held by the temporary holder 120 so as not to interfere with the wire harness assembly work table device 130. Therefore, the interference between the temporary assembly 16 and the wire harness assembly work table device 130 is effectively prevented, and the wire harness 10 can be manufactured more easily. [0085] Note that the interference prevention members 160, 162, and 164 need not be all provided, and only one or two of them may be provided.

[0086] <2- 2. Auxiliary device for assembling wire harness according to second example>

In the auxiliary device for assembling the wire harness according to the second example, the same configuration as that of the temporary holder 120 shown in FIGS. 4 and 5 is used. Is omitted.

FIG. 9 and FIG. 10 are explanatory diagrams showing the wire harness assembly work table device, the temporary holding fixture mounting portion, and the temporary holding fixture moving support portion, and FIG. 11 and FIG. FIG.

[0088] The wire harness assembly workbench apparatus 30 according to the second specific example of the wire harness assembly workbench device 30, the temporary attachment holder mounting portion 40, and the temporary attachment holder movement support portion 50, temporary attachment The holder mounting part 240 and the temporary holder moving support part 250 will be described.

Since the wire harness assembly work table device 230 has the same configuration as that of the wire harness assembly work table device 130, the same components are denoted by the same reference numerals and the description thereof is omitted. In this wire harness assembly work table apparatus 230, the main work surface 131 is an area in which the trunk portion 12 of the wire harness 10 is oriented in a substantially horizontal direction and is biased to the lower side of the main work surface 131. Hold in (lower half area). Specifically, in order to hold the wire harness 10 in such a state, a support for the wire harness 10 is erected at an appropriate position. Normally, the trunk portion 12 of the wire harness 10 is biased from the true center position in a predetermined wiring configuration. Therefore, the wiring form of the wire harness 10 on the main work surface 131 is set so that the main line portion 12 is biased to the lower side of the main work surface 131.

[0090] Temporary holding fixture mounting portion 240 is configured so that temporary holding fixture 120 is substantially parallel to main work surface 131 and has a posture (substantially horizontal posture) along the direction in which main line portion 12 extends. ) Can be mounted. In addition, the temporary holding tool moving support portion 250 is configured to support the temporary holding tool mounting portion 240 so as to be movable in a substantially horizontal posture at a corresponding portion of a region that is biased to the lower side of the main work surface.

[0091] More specifically, the temporary holding fixture mounting portion 240 is a member formed of a resin, a metal plate, or the like. A pair of receiving portions 242 into which the lower ends of both ends of the temporary holder 120 can be fitted. The pair of receiving portions 242 are attached to the distal end portion of the support rod portion 256, which will be described later, and the distal end portion of the interference prevention member 260, and are disposed and fixed at a distance corresponding to the length of the temporary holder 120. Has been. Then, by fitting the lower ends of both ends of the temporary holder 120 into the pair of receiving parts 242, the temporary holder 120 is detachably attached to the temporary holder attachment part 240. Further, in the state in which the temporary holder 120 is attached to the temporary holder 120 in this way, the end of the temporary 16 held by the temporary holder 120 is in a direction away from the main work surface 131. In addition, the intermediate portion of the temporary assembly 16 is extended to the main work surface 131 side.

[0092] Temporary holding tool movement support portion 250 is attached to guide rail member 252 arranged above the work plate 132 in a substantially horizontal direction, and is reciprocally attached to the guide rail member 252. The movable member 254 and a support bar portion 256 attached to the movable member 254 are provided. The support rod portion 256 is supported by the movable member 254 in a cantilever manner so as to extend in a posture substantially parallel to the main work surface 131 from the movable member 254 and substantially orthogonal to the main line portion 12. The movable member 254 is preferably movable with a pushing force of about 5N, for example, from the viewpoint of reducing the burden on the operator.

[0093] Then, the pair of receiving portions 242 are spaced apart from each other along the substantially horizontal direction at the distal end portion of the support rod portion 256 and the distal end portion of the interference preventing member 260 supported by the support rod portion 256. It is supported like this.

Thus, the temporary holder 120 attached to the temporary holder attachment part 240 is supported in a substantially horizontal position so as to be movable along the substantially horizontal direction.

[0095] The wire harness assembling auxiliary device according to the first example includes a wire harness assembling work table device 130, a temporary holding fixture mounting portion 240, and a temporary holding fixture moving support portion 25 as described above.

It is configured with 0.

[0096] Further, the auxiliary device for assembling the wire harness includes each temporary binding held by the temporary holder 120.

The 16 hanging portions are provided with an interference preventing member 260 for preventing interference with the wire harness assembly work table device 130.

More specifically, the interference preventing member 260 is a member made of metal or resin, Temporary holding fixture mounting portion 240 Linear interference preventing portion 262 arranged in parallel with a distance from temporary holding fixture 120 attached to 240, and the movement start end side of linear interference preventing portion 262 11 (the left end portion in FIG. 11) and a closing portion 264 that closes the end portion (the left end portion in FIG. 11) on the movement start end side of the temporary holder 120, It is formed in a shape that lies on the side of an approximately J-shape. It should be noted that here, the end portion on the movement end end side of the temporary holder 120 and the end portion on the movement end end side of the linear interference preventing portion 262 are also closed by the front end portion of the support rod portion 256. .

[0098] Then, with the temporary holder 120 attached to the temporary holder holder 240, the intermediate portion of the temporary holder 16 hanging from the temporary holder 120 so as to draw a substantially U-shape, Pull out through the gap between the temporary holder 120 and the linear interference prevention part 262 of the interference prevention member 260, and place it on the linear interference prevention part 262 of the interference prevention member 260 (see FIGS. 11 and 12). . As a result, the intermediate portion of each temporary connection 16 is guided downward away from the main work surface 131, and interference with members on the main work surface 131 side is prevented.

[0099] In this state, both ends of the gap between the temporary holder 120 and the linear interference preventing portion 262 are closed by the end portions of the closing portion 264 and the support rod portion 256. The intermediate part is difficult to be removed from between the temporary holder 120 and the linear interference preventing part 262.

[0100] With the wire harness assembling auxiliary device configured as described above, the wire harness 10 can be manufactured by the same procedure as described above.

[0101] Therefore, in the same manner as described above, it is possible to easily manufacture the wire harness 10 from the temporary connection 16 by delivering the temporary connection 16 with a relatively simple configuration while preventing the temporary connection 16 from being entangled. it can.

[0102] In particular, the temporary holding fixture mounting portion 240 has a posture (substantially horizontal posture) in which the temporary holding fixture 120 is substantially parallel to the main work surface 131 and along the direction in which the trunk portion 12 extends. ) And is supported so as to be movably supported in a substantially horizontal posture at a corresponding portion of a region that is biased downwardly from the main work surface. For this reason, the end of each temporary connection 16 held by the temporary connection holder 20 can be disposed at a position close to the main line portion 12. Here, normally, each temporary connection 16 is transferred from the fixed position of the end part belonging to a predetermined group Gl to G7 to another gnole G1 to G7 via the trunk portion 12. It is attached toward the fixed position of the end part to which it belongs. Therefore, by supporting the end of each temporary connection 16 held by the temporary connection holder 20 movably at a position close to the main line portion 12, for example, one end of the temporary connection 16 is attached to the main work surface 131. There is an advantage that the temporary connection 16 is hardly pulled in a state where it is disposed and the other end is held by the temporary connection holder 20.

[0103] Further, since the suspension part 260 of each temporary holding 16 held by the temporary holding tool 120 is provided with an interference preventing member 260 for guiding the hanging part so as not to interfere with the wire harness assembly work table device 230, the temporary holding tool 120 is temporarily provided. Interference between the connection 16 and the wire harness assembly work table device 230 is effectively prevented, and the wire harness 10 can be manufactured more easily.

[0104] Moreover, the interference preventing member 260 includes a linear interference preventing unit 262 disposed in parallel with a space with respect to the temporary holding holder 120 attached to the temporary holding holder attaching portion 240. Since there is a blocking portion 264 that closes between the end of the linear interference preventing portion 262 and the end of the temporary holder 120, the hanging portion of the temporary connection 16 is temporarily connected to the interference preventing member 260 and If it is placed between the tie holders 120, it will be difficult to remove it. For this reason, during the assembly work of the wire harness 10, the interference between the temporary connection 16 and the wire harness assembly work table apparatus 230 can be more effectively prevented.

[0105] Furthermore, since the temporary holding fixture mounting portion 240 is configured to hold the temporary holding holder 120 by a pair of receiving portions 242 arranged at intervals, before the temporary holding fixture 120 is attached, The force S can be easily disposed in the interference preventing member 260 through the pair of receiving portions 242 through the hanging portion of the temporary connection 16.

Note that the configuration of the interference preventing member 260 is not limited to the above example.

For example, in the example shown in FIG. 13 and FIG. 14, the interference preventing member 360 is moved toward the movement start end side by the length of the temporary holder 120 along the movement direction A of the front end force of the support bar portion 256. And is connected to the end portion on the movement start end side of the temporary holder attaching portion 340.

[0108] Further, the temporary holding fixture attaching portion 340 is formed in a long member similar to the temporary holding fixture attaching portion 140, and is connected and fixed to the free end portion of the interference preventing member 360. . The virtual holder attaching portion 340 is disposed so as to extend from the free end portion of the interference preventing member 360 along the moving direction A toward the moving end end side. That is, the temporary holding fixture attaching portion 340 and the interference preventing member 360 as a whole have a shape that is substantially U-shaped.

[0110] The interference prevention member 360 as described above is also provided with a linear interference prevention unit 362 arranged in parallel to the temporary attachment holder 120 attached to the temporary attachment holder attachment portion 340, and a linear shape. It can be grasped as a member having a closing portion 264 that closes between the end portion on the movement start end side of the interference prevention portion 362 and the end portion on the movement start end side of the temporary holder 120.

[0111] The interference preventing member 360 can also more effectively prevent interference between the temporary connection 16 and the wire harness assembly work table apparatus 230. In addition, since one of the gaps between the linear interference preventing portion 362 of the interference preventing member 360 and the temporary holder 120 is closed by the closing portion 364, the hanging portion of the temporary attachment 16 is connected to the interference preventing member 360 and the temporary holding fixture 120. It is difficult to remove from the tie holder 120.

[0112] Of course, even if there is no configuration corresponding to the blocking portions 264, 364, it is possible to prevent the bonding 16 from interfering with the wire harness assembly work table apparatus 230.

[0113] <3. Variations etc.>

Note that the temporary holders 20 and 120 need not be assigned to one wire harness assembly work table device 30 in a one-to-one relationship. For example, there is a relationship in which a plurality of temporary holders 20 are assigned to one wire harness assembly work table apparatus 30, or one or a plurality of temporary connection holders are held by a plurality of wire harness assembly work table apparatuses 30. The component 20 may be shared.

[0114] Also, the temporary holding fixture mounting portion 140 and the temporary holding fixture moving support portion 150 need not be assigned to one tire harness assembly work table device 30 in a single relationship. For example, the temporary holding fixture mounting portion 140 and the temporary holding fixture moving support portion 150 are attached to the annular guide rail member so as to circulate and rotate, and a plurality of wire harness assemblies are assembled along the guide rail member. A work table device 30 may be provided.

[0115] As described above, the auxiliary device for assembling the wire harness and the method for manufacturing the wire harness have been described in detail. However, the above description is illustrative in all aspects, and the present invention is limited thereto. It is not a thing. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
