TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an electric wire supply shelf that is used in a manufacturing process of a wire harness (automotive assembled electric wire) in which a plurality of electric wires are grouped and wired, and sorts and stores the same type of electric wires.
[0002]
[Prior art]
The wire harness is obtained by bundling and wiring a plurality of electric wires by tape winding or the like, and includes a trunk line and a branch line folded back from the trunk line. Exterior parts such as protectors and grommets are attached to the wire harness as needed, and an electric connection box such as a junction box is connected. Terminals are connected to the terminals of the wire harness. A plurality of terminals are accommodated in a connector housing, and signals are exchanged between components mounted on the vehicle by performing connector connection.
[0003]
The manufacturing process of such a wire harness includes a plurality of processes, and generally includes a preprocess, a subassembly process, a wiring process, an exterior component mounting process, and an inspection process.
[0004]
Each of these steps will be briefly described below.
The pre-process is a process of cutting an electric wire having no terminal at both ends, peeling off the insulation coating, and then crimping the terminal to the core portion of the electric wire to produce an electric wire with a terminal. There are many types of wires with terminals that differ in the length and thickness of wires, the size and shape of terminals, and the like. The electric wire with a terminal is used for producing a sub-harness in a sub-assembly process.
[0005]
The sub-assembly step is a step in which various electric wires are combined in a connector unit, and terminals are accommodated in a terminal accommodating chamber of the connector housing to produce a sub-harness.
The wiring step is a step of two-dimensionally wiring a plurality of sub-harnesses prepared for each connector using a plurality of fork-shaped locking pins or the like so as to substantially conform to a wiring configuration in an automobile.
[0006]
The exterior component mounting process is a process of mounting exterior components such as a protector for protecting the wire harness from interference with the outside and a grommet for soundproofing and waterproofing with a tape or the like. The inspection step is a step of checking for disconnection, crimping failure and the like using a continuity checker. In the continuity test, continuity is inspected for each connector by fitting a connector into a housing receiver of the continuity checker. In the appearance inspection, the whole is observed and inspected for defects or defects.
[0007]
In short, a plurality of electric wires with terminals are assembled and wired in connector units to produce a sub-harness as an intermediate product, and a wire harness as a final product is manufactured by combining the plurality of sub-harnesses.
[0008]
Here, in the conventional manufacturing process of a wire harness, when manufacturing a sub-harness, there is a problem that an operator makes an incorrect wire and manufactures a sub-harness with an incorrect wire. In order to prevent such mistakes, there is an invention related to an electric wire supply shelf that sorts and stores electric wires for each type.
[0009]
FIG. 6 shows an electric wire supply shelf disclosed in Japanese Patent Application Laid-Open No. H8-83522 previously proposed by the present applicant as an example of a technique related to this kind of electric wire supply shelf.
[0010]
As illustrated, the electric wire supply shelf 50 includes a shelf main body 51, an electric wire storage body 58, and an opening / closing cover 54. The shelf main body 51 has a skeleton structure formed by assembling a plurality of pipes. The shelf main body 51 is provided with four legs 52a, 52a, 52b, 52b having casters 53. The two front legs 52a, 52a are short, and the two rear legs 52b, 52b are long. For this reason, the cradle of the shelf main body 12 is inclined forward and downward.
[0011]
The electric wire housing 58 includes a plurality of cylinders 59 arranged in a horizontal row. Inside the cylinder 59, many electric wires 60 of the same type are stored. The electric wire 60 protrudes from the rear end of the tube 59 and hangs down.
[0012]
The electric wire 60 is a terminal-equipped electric wire with terminals (not shown) crimped to both ends. The electric wires 60 have different thicknesses and lengths for each type. A predetermined electric wire 60 is taken out from the tube 59 and assembled and wired in a connector unit to produce a sub-harness.
[0013]
The opening / closing cover 54 is provided at the front end of the cylinder 59. For this reason, the opening formed at the front end is in a state of being closed by the opening / closing cover 54. The opening / closing cover 54 includes a lid 56 that opens and closes on a frame 55, and a control unit 57 for the lid 56. The cover 56 is opened by a signal from the control unit 57, and the necessary electric wire 60 can be taken out at that time. For this reason, it is prevented that an operator mistakenly takes out the electric wire 60 and manufactures the sub-harness.
[0014]
[Patent Document 1]
JP-A-8-83522 (page 3, FIG. 1)
[0015]
[Problems to be solved by the invention]
However, the conventional electric wire supply shelf has the following problems to be solved.
[0016]
For one thing, there is a concern that the wire 60 protruding from the rear end of the tube 59 and hanging therefrom may become entangled. When the electric wires 60 are entangled with each other, a tension is generated when a tensile force is applied to the electric wires 60, and the electric wires 60 may be broken or damaged. In particular, the thinner the electric wire 60, the more likely it is that damage such as disconnection will occur. Such a problem occurs when the electric wire 60 is longer than the cylinder 59. When the electric wire 60 is shorter than the tube 59, the electric wire 60 fits into the tube 59, so that the electric wire 60 does not protrude from the tube 59 and does not hang down.
[0017]
On the other hand, when the types of the electric wires 60 increase, the number of the cylinders 59 constituting the electric wire storage body 58 increases, and the shelf main body 51 on which the electric wire storage body 58 is mounted becomes large. is there. When the size of the shelf body 51 increases, the work space in the factory becomes narrower, and the workability deteriorates. Further, when the cylinders 59 are long in a horizontal line, there is a problem that the labor of an operator who takes out the electric wires 60 also increases the work efficiency and deteriorates the work efficiency.
[0018]
Furthermore, when removing the electric wire 60 from the tube 59, the end of the hanging electric wire 60 rubs against the rear end of the tube 59, or the terminal crimped to the end of the electric wire 60 is caught on the rear end of the tube 59. In some cases, the electric wire 60 may be damaged. The terminal is hooked because the electric contact portion and the wire connection portion protrude outward.
[0019]
In view of the above, an object of the present invention is to provide an electric wire supply shelf that can prevent an electric wire from being damaged by entanglement of an end of the electric wire.
[0020]

[0023]
According to the above configuration, since the angle formed between the upper cylinder and the lower cylinder is arranged in the cross direction so as to form an acute angle, the electric wire is bent in a U-turn shape and stored in a pair of the upper cylinder and the lower cylinder. Is done.
[0024]
According to a third aspect of the present invention, in the wire supply shelf according to the first or second aspect, the upper tube overlaps in a plurality of stages, and the upper upper tube projects rearward from the lower upper tube. Features.
[0025]
According to the above configuration, the upper upper cylinder projects rearward from the lower upper cylinder, so that the inner electric wire and the outer electric wire bent in a U-turn shape are prevented from coming into contact with each other and becoming entangled.
[0026]
According to a fourth aspect of the present invention, in the electric wire supply shelf according to the first or second aspect, the lower cylinders overlap in a plurality of stages, and the lower cylinder lower than the upper cylinder projects rearward. Features.
[0027]
According to the above configuration, since the lower cylinder below the upper cylinder protrudes rearward than the lower cylinder, the inner wire and the outer wire bent in a U-turn shape are prevented from contacting and becoming entangled. .
[0028]
According to a fifth aspect of the present invention, in the electric wire supply shelf according to any one of the first to fourth aspects, a pair of guide members for guiding the electric wire bent on both sides of the open end of the upper cylinder. Is provided.
[0029]
According to the above configuration, since the guide members are disposed on both sides of the open end of the upper tube in which the electric wires are bent, the electric wires respectively housed in the upper tubes adjacent in the lateral direction are guided by the guide members. At the same time, partitioning by the guide member prevents entanglement.
[0030]
According to a sixth aspect of the present invention, in the electric wire supply shelf according to any one of the first to fifth aspects, a support member that supports the bent electric wire at a position facing an opening end of the upper cylinder. Is provided.
[0031]
According to the above configuration, since the support member is provided at the open end of the upper cylinder, when the electric wire is taken out from the electric wire supply shelf, the pulled electric wire is caught by the opening edge of the upper cylinder, and the electric wire may be damaged. Is prevented.

[0034]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific examples of the embodiments of the present invention will be described in detail with reference to the drawings.
1 to 3 show one embodiment of an electric wire supply shelf according to the present invention.
[0035]
The wire supply shelf 10 according to the present invention is used in the sub-assembly process of the next process following the wire cutting and crimping and the wire stripping as the preceding processes in the wire harness manufacturing process shown in FIG. The sub-assembly process includes an electric wire setting operation, a joint operation, and a case fitting operation. The electric wire supply shelf 10 inserts an electric wire with terminals 48 (FIG. 2) into a terminal accommodating chamber of a connector housing (not shown) to insert a sub-harness ( (Not shown). The description of the pre-process and the post-process after the production of the sub-harness is the same as the description in the column of the related art, and thus the description is omitted here.
[0036]
As shown in FIG. 1, the electric wire supply shelf 10 includes a shelf main body 12 and an electric wire housing 30. On the front side of the electric wire supply shelf 10, there is provided an electric wire guiding device 40 for guiding the removal of the electric wire 48 (FIG. 2). The electric wire guiding device 40 as a peripheral device will not be described in detail here because it will be described in another application. However, the device main body 41, the confirmation switches 42, the indicating lamps 43, the continuity checker 44, and the like are included. It is provided with.
[0037]
The operation of the electric wire guiding device 40 will be briefly described. First, when assembling and wiring the sub-harness for each connector, the operator instructs the electric wire 48 to be inserted into the terminal accommodating chamber of the connector housing by turning on or off the indicator lamp 43. The operator takes out the electric wire 48 at the position where the indicator lamp 43 is lit or flashes, inserts the electric wire 48 into a predetermined position of the terminal housing chamber of the connector housing, and presses the confirmation switch 42.
[0038]
Again, the electric wire guidance device 40 turns on or blinks the instruction lamp 43 and indicates the next electric wire 48. Similarly, the operator takes out a predetermined electric wire 48 according to the instruction lamp 43 and inserts it into the terminal receiving chamber of the connector housing. By repeating such an operation until the sub-harness is completed, the sub-harness is accurately manufactured without the operator taking out the wrong electric wire 48. Then, after completing the sub-harness, the conduction checker 44 inspects the connector for conduction such as disconnection or crimping failure of the electric wire 48. Each time the electric wire 48 is inserted into the connector housing, it is possible to inspect whether the conduction is good or bad.
[0039]
According to the electric wire guiding device 40, the order of taking out the electric wires 48 only by turning on or blinking the indicating lamp 43 is sequentially instructed without the necessity of the open / close cover 54 provided with the cover 56 and the control unit 57 as in the conventional example. Therefore, the structures of the electric wire supply shelf 10 and the electric wire guiding device 40 are simplified, and the cost can be reduced.
[0040]
As shown in FIG. 1, a shelf main body 12 as an electric wire supply shelf 10 has a frame structure in which pipe-shaped members are assembled, and is configured in two stages, upper and lower. Lower cylinders 35 and 36 are attached to the lower stage 14, and upper cylinders 31 and 32 are attached to the upper stage 20. The pair of upper cylinders 31, 32 and lower cylinders 35, 36 constitute the electric wire housing 30.
[0041]
The frame structure of the lower stage 14 is composed of two front legs 15a, 15a and two rear legs 15b, 15b, and a horizontal member 17 connecting the adjacent legs 15a, 15b. The horizontal member 17 is connected to lower and upper portions of the legs 15a and 15b. The number of the legs 15a and 15b is determined in consideration of the strength of the shelf body 12, and the strength of the shelf body 12 can be increased by increasing the number of the legs 15a and 15b.
[0042]
Further, a plurality of mounting members 18, 18, 18, 18 (FIG. 2) for mounting the lower cylinders 35, 36 are connected to the horizontal member 17 facing the left-right direction (width direction) Y. The reason why the number of the mounting members 18 is four in total is that the lower cylinders 35 and 36 are mounted in an upper and lower tier. When the lower cylinders 35 and 36 are stacked in three or more stages, it is necessary to connect six or more attachment members 18 to the horizontal member.
[0043]
At the lower ends of the four legs 15a, 15a, 15b, 15b, casters 16 are provided as leg rings. The electric wire supply shelf 10 can smoothly move the floor by rotating the casters 16.
[0044]
Here, for convenience of description of the present invention, distinction between front and rear, left and right, and up and down will be defined. The front side means a side on which the electric wire 48 is taken out from the electric wire supply shelf 10 or a side on which the electric wire guiding device 40 shown in FIG. 1 is provided. The rear side refers to a side where the electric wire 48 is led out from the upper cylinders 31 and 32 and bent in a U-turn shape (FIG. 2). The distinction between left and right is not performed because it is symmetric. The left-right direction Y is defined as a direction in which the upper cylinders 31, 32 or the lower cylinders 35, 36 are arranged in a line. The upper side is the side where the upper cylinders 31 and 32 are provided, and the lower side is the side where the lower cylinders 35 and 36 are provided.
[0045]
The frame structure of the upper stage 20 includes two front legs 21a, 21a, two rear legs 21b, 21b, and a horizontal member 17 and a mounting member 18 connecting these legs 21a, 21a, 21b, 21b (FIG. 2). It is composed of The horizontal member 17 protrudes forward (FIG. 2). At the front end of the protruding horizontal member 17, a mounting member 22 (FIG. 2) for mounting the upper cylinders 31, 32 is formed. A mounting member 22 is also formed on the upper ends of the front legs 21a, 21a. The rear leg 21b is formed in an L-shape or an inverted L-shape, and an attachment member 22 is formed at an intermediate portion of the rear leg 21b and at a position closer to the upper portion.
[0046]
A total of four mounting members 22 for mounting the upper cylinders 31 and 32 are formed, two on each of the front side and the rear side (FIG. 2). Since the two front mounting members 22 are located at a lower position than the two rear mounting members 22, the upper cylinders 31, 32 are mounted so as to be inclined forward and downward.
[0047]
As shown in FIG. 2, the electric wire 48 is a terminal-equipped electric wire having a terminal (not shown) connected to an end by crimping or the like. The terminal is formed by punching and bending a conductive substrate. Such an electric wire 48 is manufactured in a pre-process of the sub-harness as described in the section of the related art. A plurality of electric wires 48 are manufactured and separately stored in the electric wire housing 30 composed of a plurality of sets of upper cylinders 31, 32 and lower cylinders 35, 36 for each type.
[0048]
Returning to FIG. 1 again, as described above, the electric wire housing 30 includes the upper cylinders 31 and 32 attached to the upper stage 20 of the shelf body 12 and the lower cylinders 35 and 36 attached to the lower stage 14 of the shelf body 12. It is composed of A plurality of upper cylinders 31 and 32 are provided and arranged in a line in the left-right direction Y (FIG. 3). In addition, they are vertically overlapped. The upper cylinders 31, 32 adjacent to each other on the left and right are arranged without a gap. The upper and lower upper cylinders 31 and 32 are arranged parallel to each other with an interval.
[0049]
The lower cylinders 35 and 36 are the same as the upper cylinders 31 and 32, and a plurality of lower cylinders 35 and 36 are arranged in a line in the left-right direction (FIG. 3). And it overlaps in two steps up and down. As described above, the configuration in which the electric power supply shelves 10 are stacked is effective as a configuration for preventing the electric wire supply shelf 10 from being enlarged. The upper cylinders 31 and 32 and the lower cylinders 35 and 36 are not limited to being stacked in two stages, but may be one stage or three stages or more.
[0050]
As shown in FIG. 2, the pair of upper cylinders 31, 32 and lower cylinders 35, 36 are arranged in a crossing direction so as to form a U-shaped or V-shaped acute angle. The upper cylinders 31 and 32 are inclined forward and downward at an inclination angle α, and the lower cylinders 35 and 36 are also inclined forward and downward at an inclination angle β. For this reason, the electric wire 48 is stored in a U-turn shape (bent). Thus, by arranging the upper cylinders 31 and 32 and the lower cylinders 35 and 36 in the cross direction, the electric wires 48 are not protruded from the cylinders 31, 32, 35 and 36, but are connected to the cylinders 31, 32, 35 and 36. It is designed to be stored. Such a configuration is particularly effective in the case of a long electric wire, and stores the electric wire 48 without increasing the depth of the electric wire supply shelf 10 (without increasing the dimension in the front-rear direction X). Can be.
[0051]
The illustrated upper cylinders 31, 32 and lower cylinders 35, 36 are square tubular bodies, but may be cylindrical tubular bodies. Further, as long as the electric wire 48 can be accommodated, it may not be a tube and may be a gutter.
[0052]
The upper cylinders 31 and 32 have a closed end 33a on one side and an open end (rear opening) 33b on the other side. One closed end 33a is arranged so as to face the front side of the shelf main body 12, and the other open end 33b is arranged so as to face the rear side. An opening (front opening) 34 for taking out the electric wire 48 is formed in the cylindrical wall on the one closed end 33a side. An electric wire 48 inserted into the lower cylinders 35 and 36 is led out from the other open end 33b. When mounting the upper cylinders 31 and 32 to the upper stage 20 of the shelf body 12, the mounting is performed with the opening 34 facing upward. The reason why the opening 34 is formed in the cylindrical wall while leaving the closed end 33a in this manner is that the electric wires 48 naturally flow from the upper cylinders 31 and 32 because the upper cylinders 31 and 32 are inclined forward and downward. This is to prevent slipping.
[0053]
The reason why the upper cylinders 31 and 32 are attached so as to incline forward is to prevent the wires 48 from friction with each other and tension being generated in the wires 48. In other words, this is for improving the slip of the electric wire 48 so that the electric wire 48 can be taken out with a small tensile force. The inclination angle α is arbitrary and is set to an angle that does not hinder workability.
[0054]
As described above, the upper cylinders 31 and 32 are two-tiered and overlap each other with a forward and backward displacement. That is, the upper cylinder 32 protrudes rearward from the lower cylinder 31. In other words, it protrudes in the lead-out direction of the electric wire 48. In this manner, the upper cylinders 31 and 32 are arranged to be shifted back and forth to prevent the electric wire 48 folded in a U-turn form from the upper and lower upper cylinders 31 and 32 from being entangled or the like, thereby being prevented from being damaged. To do that.
[0055]
As shown in FIG. 4, a pair of vertical members (guides) for guiding the electric wire 48 (FIG. 2) folded in a U-turn so as not to be entangled so as to face both sides of the open end 33 b of the upper cylinders 31 and 32. It is also effective to provide a (member) 28. The vertical member 28 is a vertical member that forms a part of a frame-shaped protection frame 25 formed integrally with the rear legs 21 b of the shelf body 12 (FIG. 2), and the upper cylinder 31 that is adjacent in the left-right direction Y. , 32. Since the vertical member 28 has a rod shape, it is prevented from being damaged when the electric wire 48 is pulled. It is also effective to form the vertical member 28 as a cylindrical roller so as to rotate with the movement of the electric wire 48. With this configuration, the electric wire 48 is guided and protected by the vertical members 28 on both sides, and is folded without being entangled with the electric wires 48 of the adjacent upper cylinders 31 and 32.
[0056]
It is also effective to provide a lower chord material (support member) 27 that supports the electric wire 48 folded in a U-turn so as to face the lower edge of the open end 33b of the upper cylinders 31, 32. Similarly to the vertical member 28, the lower chord member 27 forms a part of a protection frame 25 integrally formed with the rear legs 21b, 21b of the shelf body 12, and is a horizontal abdominal member. Since the lower chord material 27 has a rod shape, when the electric wire 48 folded in a U-turn shape is stored in the lower cylinders 35 and 36, it is prevented from being bent at an acute angle and broken.
[0057]
The protection frame 25 is a lattice-like or frame-like frame in which the vertical member 28 and the lower chord member 27 are integrally formed, and the rear legs 21b and the rear legs 21b and It is provided at the end of 21b. The rectangular frame defined by the vertical material 28 on both sides and the lower chord material 27 and the upper chord material 26 faces the open ends 33 b of the upper cylinders 31 and 32.
[0058]
Returning to FIG. 2, the lower cylinders 35 and 36 are formed to penetrate with open ends 37a and 37b on both sides. An electric wire 48 led out from the upper cylinders 31 and 32 is inserted into the rear opening end 37b. The electric wire 48 does not protrude from the front open end 37a. As described above, since the electric wires 48 are housed in the lower cylinders 35 and 36, damages due to entanglement of the electric wires 48 and the like are prevented.
[0059]
Similarly to the upper cylinders 31, 32, the lower cylinders 35, 36 also overlap in two stages in an inclined state. The upper and lower cylinders 35 and 36 are arranged in parallel with each other and at an interval. Further, the lower cylinder lower than the upper cylinder protrudes rearward, and the lower cylinders 35 and 36 overlap with each other in a manner shifted forward and backward. The reason why the upper and lower lower cylinders 35 and 36 are shifted back and forth is that the pair of upper cylinders 31 and 32 and the opening ends 33b and 37b of the lower cylinders 35 and 36 are brought close to each other to reduce the exposure of the electric wire 48. This is to avoid interference between the inner electric wire 48 and the outer electric wire 48 which are turned back.
[0060]
【The invention's effect】
As described above, according to the first aspect of the present invention, the upper cylinder is attached to the upper stage of the shelf main body, the lower cylinder is attached to the lower stage of the shelf main body, and one side half of the electric wire is stored in the upper cylinder. The other half of the bent wire drawn out of the upper tube is stored in the tube. For this reason, the electric wires are stored in both the cylinders and are prevented from protruding. Therefore, entanglement of the electric wires is prevented, and the electric wires are protected.
[0061]
According to the second aspect of the present invention, the electric wire is bent into a U-turn shape and is stored in the upper tube and the lower tube without protruding from the shelf main body. Therefore, it is possible to prevent the long electric wire from becoming entangled.
[0062]
According to the third or fourth aspect of the present invention, even when the upper cylinder or the lower cylinder overlaps in a plurality of stages, the inner wire and the outer wire bent in a U-turn form come into contact with each other. Tangles are prevented. Therefore, the same effect as that of the first aspect can be obtained without causing damage to the electric wire.
[0063]
According to the fifth aspect of the present invention, the electric wires housed in the upper cylinders adjacent in the left-right direction are guided and protected by the guide member, and are separated by the guide member to prevent the electric wires from becoming entangled. Therefore, in addition to the effect of claim 1, contact between adjacent electric wires is effectively prevented.
[0064]
According to the sixth aspect of the present invention, when the electric wire is taken out from the electric wire supply shelf, the pulled electric wire is prevented from being caught by the opening edge of the upper cylinder, thereby preventing the electric wire from being damaged. Therefore, in addition to the effect of the first aspect, damage at the time of taking out the electric wire is prevented.
[0065]
According to the seventh aspect of the present invention, since the guide member and the support member are integrally formed, the manufacturing is simplified and the assembling workability is improved. Therefore, it is possible to provide an electric wire supply shelf which can prevent electric wire damage at low cost.
