Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestal for stocking wire harness subassemblies in advance.

[0002]

2. Description of the Related Art A wire harness is composed of a large number of electric wires gathered together, but these large numbers of electric wires are not bundled together at once.
That is, most wire harnesses are divided into multiple subassemblies. After assembling the individual sub-assemblies, the sub-assemblies are bundled (referred to as "main binding") to form a wire harness. Referring to FIG. 3, the sub-assembly includes, for example, 10 to 30 electric wires 1, and one or more connectors C are attached to these terminal portions. The wire harness is assembled using such a sub-assembly as a unit.

That is, the sub-assembly is a part for carrying out the main binding work. Therefore, when this binding work is performed on the assembly line, a sufficient number of subassemblies are stocked in advance as a prerequisite for the smooth progress of the work, and the sub-assemblies are ready to be sequentially supplied on the assembly line. There is a need. Therefore, in the conventional case, as shown in FIG.
The sub-assemblies were stocked by the dolly as shown in.

With reference to FIG. 4, this trolley 2 has a holding member 3, a supporting column 4 for supporting the supporting member 3, and a base 5 for supporting the supporting column 4. The holding member 3 is formed by connecting elongated rail members 3a, 3b, 3c, 3d in a cross shape. The assembled sub-assembly SA is adapted to be hooked and held on the rail members 3a, 3b, 3c, 3d. Specifically, as shown in FIG. 5, in the assembled sub-assembly SA, the connectors C are gathered together and stopped by a rubber band G, or a tape is wound and temporarily fixed. As a result, the electric wire 1 included in the subassembly SA is kept in a ring shape. Then, the subassembly SA can be hooked and held by passing the electric wire 1 held in a ring shape through the rail members 3a, 3b, 3c or 3d.

[0005]

However, the conventional trolley 2
Then, there were the following problems. That is, FIG.
With reference to, adjacent rail members (for example, 3a, 3b) are
Since the angles are about 90 ° apart, both rail members 3a, 3
Between b, there is a wasted space not involved in holding the subassembly SA. In order to eliminate this useless space, the number of rail members 3a and 3b is increased to increase the holding member 3.
It is conceivable to arrange them radially. However, when the holding members 3 are arranged radially, the distance between the rail members 3a, 3b, 3c, 3d becomes narrow near the center CL of the holding member 3. Therefore, in the vicinity of the center CL, the connectors C cannot contact each other to hold the subassembly SA, and as a result, a useless space that is not involved in holding the subassembly SA is formed. As described above, in the conventional bogie 2, the stock capacity of the sub-assembly SA cannot be secured so large that the space efficiency is poor.

Since the holding member 3 is formed in a cross shape, the subassembly SA is attached to the rail members 3a, 3b,
In the case where the sub-assemblies SA are sequentially hooked to the 3c and 3d and when the sub-assemblies SA are sequentially taken out from the rail members 3a, 3b, 3c and 3d, the worker moves around the holding member 3 or the carriage 2 I have to rotate.

Moreover, the rail members 3a, 3b, 3
In many cases, the sub-assembly SA hooked on c and 3d does not face straight upward and is inclined obliquely from the rail members 3a, 3b, 3c and 3d. In this way, when the hooked sub-assemblies SA are inclined, the respective sub-assemblies SA are not properly aligned on the holding member 3,
It becomes difficult to take out the sub-assembly SA from the holding member 3.

Further, if the respective sub-assemblies SA are not properly aligned on the holding member 3, especially the holding member 3
The subassembly SA held near the center CL of
Are so dense that the hanging wires 1 are easily entangled with each other. Thus, when the electric wires 1 are entangled with each other, a very troublesome work must be performed to remove the entanglement between the electric wires 1.

The connector holding portion A includes a plurality of U-shaped members 10 and a connecting member 20 that connects the U-shaped members 10 in parallel with each other at a predetermined interval. That is, the connector holding portion A is in a state in which the plurality of U-shaped members 10 are arranged in parallel on the same plane.

Each U-shaped member 10 is formed by forming a round bar 11 into a substantially U-shape. Then, as a result of the plurality of U-shaped members 10 being arranged in parallel at a constant narrow interval, the connector of the sub-assembly is supported by the pair of round bars 11 included in the U-shaped members 10 adjacent to each other. It is like this. With the above-mentioned predetermined interval,
The distance is such that the connector can be supported in a state of being bridged between the round bars 11, and a plurality of electric wires connected to the connector can hang down between the pair of round bars 11. In addition, in order to secure sufficient rigidity of the U-shaped member 10, cross members 12 are arranged between the round bars 11 of each U-shaped member 10 (in this embodiment, three positions). There is.

The connecting member 20 has a comb shape. The connecting member 20 is arranged so as to project upward from the arrangement surface of the U-shaped members 10 and connects the cross members 12 of each U-shaped member 10 to each other. As a result, the U-shaped members 10 are arranged such that the one end 10a side, that is, the side curved in a substantially U-shape is aligned. Therefore, the one ends 10a side of the pair of round bars 11 are curved in a direction away from each other. On the other hand, each U-shaped member 10
The other end 10b side, that is, the open end side, is bent so as to flip up.

The supporting portion B has a pillar member 30 for supporting the connector holding portion A and legs 40. In this embodiment, an elongated flat plate member is adopted as the column member 30, and two U-shaped members 10 are connected to each of them. That is, the upper end of one pillar member 30 is
It is connected to the cross member 12 on the one end 10a side,
The upper end of the other pillar member 30 is connected to the cross member 12 on the other end 10b side. Further, the lower ends of the pillar members 30 are connected to the legs 40.

One side of the pillar member 30, that is, the one connected to the cross member 12 on the one end 10a side of the U-shaped member 10 is more than the pillar member 30 connected to the cross member 12 on the other end 10b side. Even, its dimensions are set long. Therefore, the connector holding portion A has the U-shaped member 1
A downward slope is formed from one end 10a side of 0 to the other end 10b side. Reference numeral 31 is a reinforcing member for reinforcing the pillar member 30, and connects the pillar member 30 and the leg 40. Further, casters 41 for movement are provided at the lower ends of the legs 40. As a result, the gantry can be easily moved.

As described above, since the cross member 12 of the U-shaped member 10 and the leg 40 are connected to each other by the elongated flat plate-shaped column member 30, vertically downward between the pair of adjacent round rods 11, A predetermined space is formed. This predetermined space constitutes an electric wire hanging portion 50 in which the electric wires of the held sub-assembly are arranged. That is, the pair of round bars 11
When supporting the connector of the sub-assembly by
The electric wire hanging from the connector is located in the electric wire hanging portion 50.

Next, how to use this mount will be described together with its function and effect. FIG. 2 is an enlarged perspective view of an essential part showing a state in which the assembled sub-assembly SA is inserted between a pair of round bars 11 formed by adjacent U-shaped members 10. Referring to FIG. 2, the assembled sub-assembly SA
The connectors C included in the sub-assembly SA are gathered together, and the plurality of electric wires 1 connected to each connector C are temporarily fixed with a rubber band G or a tape.

The bundled electric wires 1 are inserted between the round bars 11 in the direction of the white arrow, and the connector C is arranged so as to bridge over between the pair of round bars 11. At this time, the electric wire 1 is U
The character-shaped member 10 is inserted from one end 10a side. As a result, each connector C is supported while being placed on the pair of round bars 11, and the plurality of electric wires 1 are connected to each other by the connector C.

The sub-assemblies SA are arranged one after another.

In this way, the subassembly SA
Can be easily stocked simply by bundling the electric wires 1 and inserting them between the round bars 11. Moreover, since the assembled connectors C are bridged over the pair of round bars 11, the sub-assembly SA does not tilt when supported, and the electric wire 1 connected to the connector C hangs vertically downward. Therefore, the subassemblies SA can be stocked in an aligned state.

On the other hand, by sliding the assembled connectors C toward the other ends 10b of the pair of round bars 11, the sub-assembly SA can be easily taken out. In particular, since the sub-assemblies SA are held in an aligned state, even if a large number of sub-assemblies SA are densely packed, the electric wires 1 are unlikely to be entangled with each other, and the work for taking out the sub-assemblies SA can be performed smoothly.

Further, since the U-shaped members 10 are juxtaposed at the above-mentioned predetermined intervals, the connector holding portion A does not have a useless space that is not involved in holding the sub-assembly SA. Therefore, the space efficiency of the connector holding portion A is good, and a large number of subassemblies SA can be stocked without wasting space. Further, the worker is to detect the other end 10b of each U-shaped member 10.
Since it is possible to work on the side, there is no need to move around the gantry or move the gantry when supporting the connector C and when taking out the sub-assembly SA. You can work. As a result, the worker can easily perform the work of stocking the sub-assembly SA and the work of taking out the sub-assembly SA.

In addition, the present embodiment has the following operational effects. First, since the one end 10a side of the round bar 11 is curved in a direction away from each other, the sub-assembly SA
When a pair of round bars 11 are held, the plurality of electric wires 1 connected to the connector C can be inserted between the round bars 11 while being guided by the curved portions. As a result, the work of stocking the sub-assemblies SA can be performed more easily.

Further, since the connector holding portion A has a downward slope from the one end 10a side to the other end 10b side, the held sub-assembly SA has the other end 1 by its own weight.
Slide to the 0b side. Therefore, when the worker takes out the held sub-assembly SA, the sub-assembly SA sequentially moves to the front side of the worker who takes out the work. As a result, the worker can more smoothly execute the sub-assembly SA.
There is an advantage that the work of taking out can be performed. Moreover, since the other end 10b side of each round bar 11 is bent upward, it is possible to prevent the subassembly SA from easily falling off the connector holding portion A. As a result, there is also an advantage that the gantry can be freely moved while stocking the sub-assembly SA.

The present invention is not limited to the above embodiment, and as shown in FIG.
A partition plate 60 may be interposed between 0s. That is, the partition plate 60 is disposed between the pair of column members 30 connected to each U-shaped member 10. Thereby, each wire hanging part 50 can be divided. In addition, in FIG. 1, in order to simplify the drawing, the pillar member 30 on the front side in the drawing is used.
Although it is provided only between them, it is actually provided between the pillar members 30 connected to each U-shaped member 10.

By providing the partition plate 60 in this way, it is possible to prevent the electric wires 1 housed between the adjacent electric wire hanging parts 50 from coming into contact with each other, and reliably prevent the electric wires 1 from being entangled with each other. You can As a result, the work of taking out the sub-assembly SA can be performed even more smoothly. Further, in the present embodiment, a plurality of pairs of round rods 11 forming a pair are formed by the adjacent U-shaped members 10, but a plurality of pairs of straight rod-shaped members forming a pair may be arranged in parallel. Further, in this case, the pair of adjacent rod-shaped members may be arranged with their heights alternately changed.
