Description

The present invention relates to an electric wire supply device that supplies electric wires to a predetermined supply destination, and an electric wire bundle manufacturing system that manufactures an electric wire bundle using the electric wires supplied from the electric wire supply device.

Conventionally, there has been known an electric wire supply device that draws an electric wire from a reel or the like around which the electric wire is wound and supplies the electric wire to a predetermined supply destination (see, for example, Patent Documents 1 to 3).

For example, one of the conventional electric wire supply devices (hereinafter referred to as "conventional device") rotates around a reel around which the electric wire is wound and a direction in which the electric wire is half-wound (the direction in which the electric wire is unwound). It is provided with a drawer (flyer) and an electric wire lead-out pipe provided at the position of the rotation shaft of the drawer (flyer). In the conventional device, when the electric wire is pulled out from the reel by rotating the drawer (flyer), the rotation of the drawer (flyer) is controlled according to the degree of the electric wire being pulled out (the amount of the electric wire supplied to the supply destination). , It is designed to prevent entanglement and twisting (so-called kink) of the electric wire due to excessive supply of the electric wire (in particular, refer to Patent Document 1).

Japanese Unexamined Patent Publication No. 7-176224 Japanese Unexamined Patent Publication No. 9-77373 Japanese Unexamined Patent Publication No. 9-9443

The above-mentioned conventional device includes a control mechanism for controlling the rotation of the drawer (flyer) in consideration of the degree of pulling out the electric wire. Although this control mechanism can suppress entanglement and twisting (kink) of electric wires, it is considered that the manufacturing cost and maintenance cost are large due to its structure. In particular, when supplying a plurality of types of electric wires to a supply destination, it is necessary to provide a plurality of conventional devices in parallel, which is considered to further increase the above-mentioned cost. From the viewpoint of reducing the manufacturing cost of the electric wire supply device (and the system including the supply destination), a device capable of exhibiting the same effect as the conventional device with a structure simpler than that of the conventional device is desired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to use an electric wire supply device capable of suppressing entanglement and twisting of electric wires by a simple structure, and an electric wire supplied from the electric wire supply device. The purpose of the present invention is to provide an electric wire bundle manufacturing system for manufacturing electric wire bundles.

In order to achieve the above-mentioned object, the electric wire supply device according to the present invention is characterized by the following (1) and (2).
(1)

The reel
It has a small diameter portion around which the electric wire is wound, and a pair of large diameter portions provided at the upper end portion and the lower end portion of the small diameter portion and each of which is in pressure contact with the elastic member.
The elastic member is
Arranged so as to fill the gap between the outer peripheral surface of each of the pair of large diameter portions and the inner wall surface of the case.

After passing between the outer peripheral surface of the large-diameter portion on the upper side and the elastic member while pressing and contacting the elastic member, the product is supplied to the supply destination through an opening provided in the upper part of the case. Be done,
Must be an electric wire supply device.

According to the electric wire supply device having the configuration of (1) above, when the electric wire is supplied to the supply destination (for example, when the electric wire is pulled out by the device of the supply destination), the electric wire is unwound from the reel (to the reel). Moves toward the supply destination (while turning around the reel in the direction opposite to the winding direction of). At this time, the electric wire passes between the outer peripheral surface of the large diameter portion of the reel and the elastic member while being pressed against the elastic member. Therefore, the electric wire is gradually pulled out without being excessively pulled out as compared with the case where there is no such pressing by the elastic member. As a result, entanglement and twisting (kink) of the electric wire due to excessive supply of the electric wire are suppressed.

Therefore, the electric wire supply device having this configuration can suppress entanglement and twisting of the electric wire by a simple structure as compared with the conventional device.

According to the electric wire supply device having the configuration of (2) above, when the electric wire is supplied from the case in the supply direction (for example, when the electric wire is pulled out by the device of the supply destination), the tension generated in the electric wire guides the tension adjusting mechanism. The tool moves in the supply direction. Then, when the electric wire is loosened between the tension adjusting mechanism and the supply destination due to a decrease in the supply amount of the electric wire, the guide tool is moved in the counter-supply direction by the urging tool, and the slack of the electric wire is eliminated. ..

As a result, entanglement and twisting of the electric wire between the tension adjusting mechanism and the supply destination can be more reliably suppressed. Further, since the slack of the electric wire between the tension adjusting mechanism and the supply destination is suppressed, even when a plurality of electric wire supply devices are provided in parallel, the electric wires extending from each electric wire supply device come into contact with each other. And entanglement is suppressed. It should be noted that such elimination of the slack in the electric wire is particularly effective when, for example, the device at the supply destination intermittently pulls out the electric wire.

By the way, "the urging tool that urges the guide tool in the counter-supply direction" may urge the guide tool by directly exerting the urging force on the guide tool, and the support tool that supports the guide tool. The guide may be indirectly urged by exerting an urging force on the.

Further, in order to achieve the above-mentioned object, the electric wire bundle manufacturing system according to the present invention is characterized by the following (3).

Hereinafter, the electric wire supply device and the electric wire bundle manufacturing system according to the embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the electric wire supply device according to the embodiment of the present invention (hereinafter referred to as "electric wire supply device 1") accommodates the bobbin-shaped reel 20 around which the electric wire 10 is wound and the reel 20 in a non-rotatable manner. A cup-shaped case 30 and a cylindrical elastic member 40 arranged between the reel 20 and the case 30 are provided. The upper wall 33 of the case 30 is provided with a circular opening 34 (through hole) formed coaxially with the axis of the case 30. The electric wire 10 is led out from the opening 34 to the outside of the case 30 and is supplied to the supply destination device 80 described later. The detailed structure of the electric wire supply device 1 will be described later.

As shown in FIG. 2, the electric wire bundle manufacturing system according to the embodiment of the present invention (hereinafter referred to as “electric wire bundle manufacturing system 2”) is a shelf on which a plurality of electric wire supply devices 1 and a plurality of electric wire supply devices 1 are arranged. A 70 and a supply destination device 80 are provided. The shelf 70 is placed on a predetermined horizontal plane. The supply destination device 80 is a device that manufactures a bundle of electric wires using a plurality of electric wires 10, and the configuration thereof is not particularly limited. As the supply destination device 80, for example, attachment (crimping) of a terminal to the electric wire 10, cutting out of the electric wire 10 having a required length, insertion of a connector of the terminal attached to the electric wire 10 into a predetermined terminal accommodating chamber, etc. Examples thereof include known devices (automatic machines) that automatically perform the above.

The metal shelf 70 has a long rectangular bottom plate 71, a long rectangular side wall 72 rising vertically from the end of the bottom plate 71, and a length extending from the upper end edge of the side wall 72 so as to face the bottom plate 71. A shelf having a U-shaped cross section, which is composed of a rectangular top plate 73 and a top plate 73.

The plurality of electric wire supply devices 1 are arranged side by side on the bottom plate 71 at predetermined intervals along the longitudinal direction of the bottom plate 71. A plurality of supply holes 74 (through holes) are formed in the top plate 73 so as to correspond to the openings 34 of the plurality of electric wire supply devices 1. The plurality of electric wires 10 led out from the openings 34 of the plurality of electric wire supply devices 1 are supplied to the supply destination device 80 through the respective supply holes 74. Although the tension adjusting mechanism 50 (see FIG. 3) is actually provided around the supply port 74, the tension adjusting mechanism 50 is not shown in FIG. 2 for convenience of explanation.

Hereinafter, the electric wire supply device 1 of one of the electric wire bundle manufacturing systems 2 will be described in detail with reference to FIGS. 3 to 5. The other electric wire supply device 1 also has the same configuration.

As shown in FIG. 3, the resin reel 20 has a small diameter portion 21 extending in the vertical direction and large diameter portions 22 and 23 coaxially provided at the upper end portion and the lower end portion of the small diameter portion 21, respectively. It has a bobbin-like (stepped columnar) shape. The outer diameters of the large diameter portions 22 and 23 are the same. An electric wire 10 is wound around the small diameter portion 21. The reel 20 is fixed to the bottom plate 71 so as not to rotate around the axis.

The resin case 30 has a cylindrical portion 31 extending in the vertical direction, a donut-shaped flange portion 32 coaxially provided at the lower end portion of the cylindrical portion 31, and a cylindrical portion at the upper end portion of the cylindrical portion 31. It has a cup-like shape including an upper wall 33 connected to the portion 31. As described above, the upper wall 33 is formed with an opening 34. The inner diameter of the inner wall surface 35 of the cylindrical portion 31 is larger than the outer diameter of the large diameter portions 22 and 23 of the reel 20. The case 30 is arranged around the reel 20 coaxially with the reel 20 so as to cover the reel 20, and is fixed to the bottom plate 71.

The elastic member 40 is made of a known elastic material such as an elastic resin foam and rubber (cushion sheet), and has a cylindrical shape. The elastic member 40 may have a cylindrical shape by winding a long plate-shaped sheet material. The elastic member 40 fills the gap between the inner wall surface 35 of the cylindrical portion 31 and the outer peripheral surfaces 22a and 23a of the large diameter portions 22 and 23 of the reel 20, and the lower end surface is in contact with the bottom plate 71. Is placed in. An annular double-sided tape 43 is provided between the outer wall surface 42 of the elastic member 40 and the inner wall surface 35 of the case 30. The case 30 and the elastic member 40 are fixed by the double-sided tape 43.

The thickness of the elastic member 40 is slightly larger than the radial dimension of the gap. Therefore, as shown in FIG. 4, the contact portion of the inner wall surface 41 of the elastic member 40 with the large diameter portions 22 and 23 of the reel 20 is elastically deformed outward in the radial direction. In other words, the large diameter portions 22 and 23 of the reel 20 are in pressure contact with the inner wall surface 41 of the elastic member 40.

As shown in FIGS. 3 and 4, the electric wire 10 wound around the small diameter portion 21 of the reel 20 passes through the outside of the outer peripheral surface 22a of the large diameter portion 22 and the opening 34 of the case 30, and then outside the case 30. It is led out to (Supply destination device 80). In particular, as shown in FIG. 4, the electric wire 10 passes outside the outer peripheral surface 22a of the large diameter portion 22 while being pressed against the elastic member 40 between the outer peripheral surface 22a and the inner wall surface 41 of the elastic member 40.

As shown in FIG. 3, a tension adjusting mechanism 50, which is a part of the electric wire supply device 1, is provided in a portion near the supply hole 74 on the upper surface of the top plate 73 of the shelf 70. That is, the tension adjusting mechanism 50 is arranged on the electric wire path between the case 30 and the supply destination device 80. Hereinafter, the constituent members related to the tension adjusting mechanism 50 will be described.

A stay 51 extending upward is fixed to a portion of the upper surface of the top plate 73 near the supply hole 74 on the side far from the supply destination device 80 with respect to the supply hole 74. The base end portion 54 of the rod-shaped pulley arm 53 is rotatably supported by the support portion 52 of the stay 51 about the support portion 52. Hereinafter, for convenience of explanation, the A direction and the B direction shown in FIG. 3 are referred to as “supply direction A” and “anti-supply direction B”, respectively.

The pulley 56 is rotatably supported by the tip end portion 55 of the pulley arm 53. Therefore, when the electric wire 10 is pulled out by the supply destination device 80 and an external force in the supply direction A is applied to the pulley 56, the pulley arm 53 rotates in the supply direction A and the pulley 56 moves in the supply direction A. It has become.

The pulley arm 53 is always urged in the counter-supply direction B by an urging tool 57 composed of a part of the pulley arm 53 and a coil spring or the like connected to the stay 51. The pulley arm 53 cannot be rotated from the rotation position in contact with the stopper 58 to the anti-supply direction B side by the stopper 58 provided on the stay 51.

On the other hand, a stay 61 extending upward is fixed to a portion of the upper surface of the top plate 73 near the supply hole 74 on the side closer to the supply destination device 80 with respect to the supply hole 74. Pulleys 62 and 63 are rotatably supported on the stay 61 so as to be arranged at predetermined intervals along the vertical direction.

As shown in FIG. 3, in the pulley 56, the electric wire 10 led out through the supply hole 74 is a part of the outer peripheral portion including the upper end portion of the pulley 56 (in FIG. 3, about 8 on the dial of the clock). It is hung in the first rotation direction (clockwise rotation direction in FIG. 3) over a range (a range corresponding to about 2 o'clock from time) and is guided toward the pulley 62.

The pulley 62 corresponds to the electric wire 10 derived from the pulley 56 from a part of the outer peripheral portion including the lower end portion of the pulley 62 (in FIG. 3, from about 8 o'clock to about 2 o'clock on the clock face). It is hung in the second rotation direction (counterclockwise rotation direction in FIG. 3) over the range) and is guided toward the pulley 63.

The pulley 63 extends the electric wire 10 led out from the pulley 62 to a part of the outer peripheral portion including the upper end portion (in FIG. 3, the range corresponding to about 8 o'clock to about 2 o'clock on the clock face). It is hung in the first rotation direction (clockwise rotation direction in FIG. 3) and guided toward the supply destination device 80. In this way, the pulleys 62 and 63 form a portion in which the electric wire path is substantially S-shaped.

Next, the operation of the electric wire supply device 1 described above will be described with reference to FIGS. 3 to 5. For example, when the supply destination device 80 pulls out the electric wire 10, the reel 20 itself does not rotate, so that the electric wire 10 is unwound from the reel 20 (in the direction opposite to the winding direction around the small diameter portion 21, the outer circumference of the large diameter portion 22). It moves toward the supply destination device 80 (while turning the outside of the surface 22a).

Specifically, the electric wire 10 moves between the outer peripheral surface 22a of the large diameter portion 22 of the reel 20 and the inner wall surface 41 of the elastic member 40 so as to rotate (turn) in the circumferential direction of the large diameter portion 22. While moving toward the supply destination device 80 through the opening 34, the supply hole 74, the pulley 56, the pulley 62, and the pulley 63.

At this time, since the electric wire 10 is pressed against the elastic member 40 between the outer peripheral surface 22a of the large diameter portion 22 of the reel 20 and the inner wall surface 41 of the elastic member 40, the electric wire 10 is gradually pulled out without being excessively pulled out. Will be. As a result, entanglement and twisting (kink) of the electric wire 10 can be suppressed as compared with the case where the elastic member 40 is not provided (excessive drawing occurs). In particular, the electric wire supply device 1 is effective for a thin electric wire 10 in which such entanglement and twisting are likely to occur.

In addition, when the supply destination device 80 pulls out the electric wire 10, as shown in FIG. 5A, the pulley 56 (in other words, the pulley arm 53) applies the tension in the supply direction A generated by the drawing out to the electric wire 10. In response to the urging force of the urging tool 57, it moves (rotates) in the supply direction A.

After that, when the supply destination device 80 temporarily suspends the drawing of the electric wire 10, the tension of the electric wire 10 weakens, so that the electric wire 10 between the pulley 63 and the supply destination device 80 becomes loose as shown in FIG. 5 (b). In some cases. However, even if the electric wire 10 is loosened in this way, as shown in FIG. 5C, the pulley arm 53 (pulley 56) rotates (moves) in the counter-supply direction B due to the urging force of the urging tool 57. ), The slack of the electric wire 10 between the pulley 63 and the supply destination device 80 is eliminated. In other words, the tension adjusting mechanism 50 constantly exerts a tension (back tension) in the anti-supply direction B on the electric wire 10. Actually, as the tension of the electric wire 10 decreases (occurrence of slack), the tension increases due to the rotation of the pulley arm 53 (elimination of slack). Therefore, the electric wire 10 as shown in FIG. 5 (b). The loosened state does not substantially occur. Due to such an operating principle, the electric wire supply device 1 is particularly effective when the supply destination device 80 intermittently pulls out the electric wire 10.

As a result, as compared with the case where the electric wires 10 are loosened, it is possible to prevent the electric wires 10 led out from the adjacent electric wire supply devices 1 (see also FIG. 2) from coming into contact with each other and being entangled with each other. Further, when the supply destination device 80 temporarily suspends the drawing of the electric wire 10, the electric wire 10 is likely to be excessively drawn out from the reel 20. As described above, the electric wire 10 is located outside the large diameter portion 22 of the reel 20 in the electric wire 10. Since the portion is pressed against the elastic member 40, the electric wire 10 is not pulled out excessively. As a result, entanglement and twisting (kink) of the electric wire 10 are surely suppressed.

As described above, according to the electric wire supply device 1 and the electric wire bundle manufacturing system 2 according to the embodiment of the present invention, when the electric wire 10 is supplied to the supply destination device 80 (specifically, the electric wire bundle manufacturing system 2). While being towed by the destination device 80), the wire 10 moves toward the destination device 80 while unwinding from the reel 20 (turning around the reel 20 in the direction opposite to the winding direction around the reel 20). .. Specifically, the electric wire 10 moves between the outer peripheral surface 22a of the large-diameter portion 22 of the reel 20 and the elastic member 40 so as to rotate (swirl) in the circumferential direction of the large-diameter portion 22, and is supplied to the supply destination. Move towards device 80.

At this time, since the electric wire 10 is pressed against the elastic member 40 between the outer peripheral surface 22a of the large diameter portion 22 of the reel 20 and the elastic member 40 (see FIG. 4), the electric wire 10 is gradually pulled out without being excessively pulled out. Will be pulled out to. As a result, entanglement and twisting (kink) of the electric wire 10 can be suppressed as compared with the case where the elastic member 40 is not provided (excessive drawing occurs).

Further, when the electric wire 10 is supplied from the case 30 in the supply direction (specifically, when the supply destination device 80 is towed), the pulley 56 of the tension adjusting mechanism 50 moves in the supply direction A due to the tension generated in the electric wire 10. (See FIG. 5 (a)). Then, when the electric wire 10 is loosened due to a reason such as a decrease in the supply amount of the electric wire 10 (specifically, the traction of the supply destination device 80 is temporarily interrupted) (see FIG. 5B), the urging tool The pulley 56 is moved in the counter-supply direction B by the 57, and the slack of the electric wire 10 is eliminated (see FIG. 5C). As a result, as compared with the case where the electric wires 10 are loosened, it is possible to prevent the electric wires 10 led out from the adjacent electric wire supply devices 1 from coming into contact with each other and being entangled with each other.

Further, the pulleys 62 and 63 in the tension adjusting mechanism 50 form a portion in which the electric wire path is substantially S-shaped. Therefore, the pull-out resistance of the electric wire 10 from the pulley 63 to the supply destination device 80 increases. This also makes it difficult for the electric wire 10 to loosen between the pulley 63 and the supply destination device 80.

Further, the tension adjusting mechanism 50 is provided with a stopper 58. As a result, the pulley arm 53 (pulley 56) does not excessively rotate (move) in the counter-supply direction B due to the urging force of the urging tool 57. As a result, it is possible to prevent excessive tension from being generated in the electric wire 10.
