Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness manufacturing apparatus for manufacturing a harness in which connectors are connected to a plurality of electric wires.

[0002]

2. Description of the Related Art Harness manufacturing apparatuses have been conventionally used for manufacturing harnesses by measuring the length of a supplied electric wire, cutting it, and connecting a connector to at least one end of the electric wire. As an example of such a harness manufacturing apparatus, for example, it is configured to supply a plurality of connectors at the same time, supply a number of electric wires corresponding to the plurality of connectors, and connect these to manufacture a plurality of harnesses at once. There is also a harness manufacturing device.

[0003]

By the way, it may be necessary to bind a plurality of harnesses manufactured by such a harness manufacturing apparatus. In this case, conventionally, the operator manually sorts the harnesses manufactured by the harness manufacturing apparatus and discharged to a tray or the like into good products and defective products, counts them, aligns both ends, and then binds them by a binding device. For this reason, a counting error has occurred, and the number of harness manufacturing devices that can be operated by one operator has been limited.

Heretofore, a harness manufacturing apparatus having a function of automatically checking the continuity of a manufactured harness has also been proposed. However, also in this case, counting and aligning both ends are left as manual work by the operator.
The reason why the operator is conventionally interposed between the harness manufacturing apparatus and the binding apparatus is as follows: (1) Harness manufactured by the harness manufacturing apparatus is pushed from the side using a cylinder or the like and dropped into the product tray. Since the harnesses are discharged from the manufacturing apparatus or are discharged by receiving the manufactured harness by a discharge clamp or the like and dropping it onto the product tray, it is not possible to supply the harness to the next step in an aligned state. (2) Even in the case of a harness manufacturing apparatus having a harness continuity inspection function, a harness determined to be a defective product is also dropped and discharged through the same route as a harness determined to be a non-defective product. The operator had to remove the harness each time. Therefore, only good products could not be counted and bound. (3) In a harness manufacturing apparatus configured to simultaneously manufacture a plurality of harnesses, the number of harnesses manufactured is usually counted up every time one cycle of the harness manufacturing process is completed. It was not possible to count any number of harnesses. For example, if three harnesses are manufactured in one cycle and 50 harnesses are to be bound together, 3 wires × 17 cycles =
It becomes 51 and cannot count 50.

In view of the above circumstances, it is an object of the present invention to provide a harness manufacturing apparatus having a function of binding manufactured harnesses without the intervention of an operator.

[0006]

In order to achieve the above object, the harness manufacturing apparatus of the present invention measures and cuts a plurality of supplied electric wires, and at the same time attaches a connector to at least one end of the electric wires. A harness manufacturing section that manufactures a harness by connecting the harness manufactured by the harness manufacturing section, and a binding section that binds the harness manufactured by the harness manufacturing section with a predetermined number of binding bands, and the harness manufactured by the harness manufacturing section to the binding section. And a transfer unit for transferring.

Here, the transfer section preferably includes an inspection section for determining whether the manufactured harness is good or bad, and a discharge section for discharging the harness determined as a defective article without transferring it to the binding section. A harness counting unit that sends a predetermined number of harnesses determined to be non-defective to the binding unit is provided. In addition, the binding unit preferably includes a harness clamp that clamps a harness fed in a predetermined number and a binding machine that binds the harness clamped by the harness clamp.

[0008]

In the harness manufacturing apparatus of the present invention, the harness is manufactured by the harness manufacturing section, the manufactured harness is sent to the binding section through the transfer section, and the harness is bound by the binding section. Without this, a harness that is bundled by a predetermined number is manufactured.

EXAMPLES Examples of the present invention will be described below. 1 is a perspective view showing the structure of a harness manufacturing apparatus according to an embodiment of the present invention, and FIG. 2 is a side view showing the harness manufacturing apparatus shown in FIG. 1 from the upper right side to the lower left side of FIG. is there.

A plurality of wires 10 are supplied to the harness manufacturing apparatus 100 via a wire inlet guide 102 from a wire supply unit (not shown). After the wire 10 is clamped by the wire clamp 104 and cut at the second pressure contact portion 120 (this cutting will be described later), the cut tip of the wire 10 is positioned at the first pressure contact portion 110. , This wire clamp 104 is a cylinder 106
Be pulled back by. On the other hand, from the first part feeder 130, a connector having pressure contact contacts is supplied to the lower pressure contact member 112 of the first pressure contact portion 110, and the lower pressure contact member 112 moves up and the upper pressure contact member 114 moves down. As a result, the wire 10 is pressure-contacted to the connector 20. Thereafter, the lower pressure contact member 112 descends and the upper pressure contact member 114 rises. After that, the measure motor 136 rotates, the measure clamp 134 advances to the position of the first press contact portion 110, and the measure clamp 13
The first pressure contact portion 1 connected to the tip of the wire 10 by
The connector 10 located at 10 or the wire 10 near the connector 20 is clamped, and in that state, the measure motor 13
6 is reversed and the measure clamp 134 returns to the position shown. As a result, the length of the wire 10 connected to the connector 20 is measured. Here, the connector is supplied from the second part feeder 132 to the lower pressure contact member 122 of the second pressure contact portion 120, and the lower pressure contact member 122 moves up and the upper pressure contact member 124 moves down, so that the wire 10 The connector is pressed and connected to the wire 10 and the wire 10 is cut. As a result, the connector 2 is attached to both ends of the wire 10 having a predetermined length.
A harness with 0 connected is manufactured.

In the above embodiment, the first pressure contact portion 11
0, the second press contact portion 120 has a first part feeder 130,
The second parts feeder 132 supplies three connectors 20 each, and the wire supply unit (not shown) supplies the number of wires 10 corresponding to the three connectors, and simultaneously manufactures three harnesses. To be done. In the harness manufactured in this manner, the connector 20 connected to the front end and the rear end of the harness has the harness pusher 140,
Continuity inspection unit 15 which is pushed by 142 and is thereby arranged on the transfer path constituted by guide rail 200.
Moved to 0. In the continuity inspection unit 150, the harness checker 152 performs the continuity inspection of the moved harness.

The harness subjected to the continuity inspection by the continuity inspection unit 150 is moved to the defect selection unit 160 by the harness pushers 140 and 142 pressing the three harnesses sequentially manufactured as described above. .. FIG. 3 is a schematic diagram showing the operation of the defect selection section 160. The defect selection unit 160 is provided with a cylinder 162, and when the continuity inspection unit 150 determines that the harness is defective, the cylinder 162 operates and moves the guide rail 200 connected to the cylinder 162. In FIG. 3, three harnesses are discharged at the same time, but the length of the guide rail 200 in the transfer path direction may be one connector, and only the defective harness may be discharged. As a result, the transfer route of the harness is interrupted, and this defective harness is discharged to the defective product tray 164 indicated by the chain double-dashed line in FIG. The harness determined to be non-defective by the continuity inspection unit 150 passes through the defect selection unit 160 and the counting unit 170.
Be transferred to. A feed pawl 172 is connected to a motor 176 via a timing belt 174 in the counting unit 170, and a predetermined number of harnesses are fed to the delivery unit 180 by the feed pawl 172. The sending portion 180 has a sending claw 1
82 is provided, and the harness that has been sent to the sending section 180 is sent to the focusing section 190 by the sending claw 182.

FIG. 4 is a schematic view (A) of the feed claw provided in the counting unit, a plan view (B) of the counting unit, the sending unit and the focusing unit,
It is a side view (C). The feed claw 172 provided in the counting unit 170 has a shaft 173, as shown in FIG.
It is configured so as to be rotatable about the center of the arrow, and is in a state of being pressed by the pressing spring 174 and in contact with the stopper 175. Here, when the motor 176 shown in FIG.
2, the connector 20 is pushed in the direction of the sending section 180 (left side in FIG. 4). After that, the motor 176 rotates in the reverse direction and the feed claw 172 returns to the original position. When the feed claw 172 returns, the feed claw 172 is pushed by the connector 20 and falls against the biasing force of the push spring 174, and Connector 20
Will be sent only in one direction of the sending unit 180. Here, by adjusting the amount of rotation of the motor 176, that is, the amount of movement of the feed claw 172, the number of harnesses delivered at one time is determined, and the number of harnesses delivered by this is counted.

The harness fed into the feeding section 180 by the feeding claw 172 is transferred to the bundling section 190 by rotating the feeding claw 182 provided in the feeding section 180 in the direction of arrow A shown in FIG. 4C. It is sent in and held by the focusing claw 192. By repeating the above operation once or a plurality of times, a predetermined number of harnesses to be bound are collectively held.

When a predetermined number of harnesses to be bundled are held by the bundling section 190 as described above, these harnesses are held by the harness clamp 210 shown in FIGS. 1 and 2, and together with the bundling claws 192. The harness held by the bundling unit 190 is delivered to the harness clamp 210. A cylinder 212 is connected to the harness clamp 210, and the cylinder 212 operates after the harness is transferred to the harness clamp 210.
The harness held at 0 is the binding claw 232 of the binding machine 230.
The harness clamp 210 is moved in the arrow B direction shown in FIG. 2 so as to be moved to the position corresponding to.

In this binding machine 230, the wire of the harness is surrounded by the binding claw 232, and the reel 23 around which the binding band is wound.
4 is a device for feeding a binding band from the binding cord 232 to the binding claw 232, and binding the wires with the binding band. The binding machine 230 is screwed into a screw rod 238 attached to the shaft of the motor 236. When the motor 236 rotates, the slide rail 2
It is guided by 39 and moves along the longitudinal direction of the harness.

FIG. 5 is a diagram schematically showing a bound harness. When the harness held by the harness clamp 210 is moved to the position corresponding to the binding claw 232, the binding machine 230 initially has the measure clamp 134 side (see FIG. 1).
1), the binding machine 230 is moved to the left in FIG. 1 to bind a plurality of parts of the harness, which allows the wires 10 and the connector 20 as shown in FIG. 5 to be connected to each other. A harness bundle in which the harnesses are bound by the binding band 30 is completed.

When the binding is completed as described above, the cylinder 214 is operated and the harness clamp 210 is moved to the position shown in FIG.
The harness clamp 210 is opened as it rotates in the direction of arrow C, and the harness bundle thus bound is discharged onto the shooter 214 and accumulated on the product tray 242. As described above, in the above embodiment, since the continuity inspection unit 150 and the defect selection unit 160 are arranged on the harness transfer path, only good harnesses can be bound.
Further, in the above-described embodiment, it is possible to send an arbitrary number of harnesses to the sending unit 180 at one time by adjusting the moving amount of the sending claw in the counting unit 170.
It is possible to bind an arbitrary number of harnesses without depending on the number of harnesses manufactured simultaneously in 10, 120.

Since this embodiment is constructed as described above, the harness is manufactured, and a predetermined number of the manufactured harnesses are bound together without the intervention of an operator. Figure 6
It is the figure which showed the other structural example of the defect selection part for discharging a defective harness. The defect selection section 360 is shown in FIG.
It can be used instead of the defect selection section 160 shown in FIG.
The lower member 402 of the
When the continuity inspection unit 150 determines that the harness is defective, the lower member 402 is opened, and the defective harness is used as the defective product tray 16.
It is discharged to 4.

FIG. 7 is a view showing another example of the harness bundle. Each harness that constitutes this harness bundle is a wire 10
The connector 20 is connected to only one end of the. Next, differences from the embodiment shown in FIGS. 1 to 5 on the side of the apparatus for making such a harness bundle will be described. Figure 8
FIG. 8 is a view showing a part of the apparatus for manufacturing the harness bundle shown in FIG. 7, which is different from the embodiment shown in FIGS. 1 to 4.

The first of the harness manufacturing apparatus 100 shown in FIG.
The connector 20 is attached to the tip of the wire 10 at the press-contact portion 110.
Is connected to the wire 10 by the measure clamp 134.
After the length is measured, the wire 10 is cut without connecting the connector 20 to the rear end side of the wire 10.
The harness manufactured in this manner, in which the connector 20 is connected to only one end of the wire 10 of a predetermined length, is pushed by the harness pusher 140 and is transferred along the guide rail 200 as in the case of the above-described embodiment. However, in order to prevent the wire 10 from hanging down at this time, as shown in FIG. 8, the electric wire cover 500 is arranged along the transfer path of the harness, and the wire 10 advances on the electric wire cover 500.
Further, as shown in FIG. 8, a handle clamp 510 is arranged adjacent to the binding claw 232 of the binding machine 230. Note that FIG.
Although the continuity inspection unit 150, the defect selection unit 160, and the defective product tray 164 are shown in the figure, a harness in which a connector is connected to only one side cannot perform the continuity inspection, and therefore these are not used. Other than that, the sequence until clamped by the harness clamp 210 is the same as the case of the above-described embodiment except that only the harness clamp 210 on one side is used.

FIG. 9 is a schematic view (A) showing a state of binding a harness in which a connector is connected to only one side of a wire,
9 is a side view (B) shown from the left side of FIG. 9 (A). The harness 20 is clamped on the connector 20 side of a predetermined number of harnesses, and the wires 10 are sequentially bound from the harness clamp 210 side.
At this time, the handling clamp 510 arranged adjacent to the binding machine 230 moves the wire 10 from the first binding for the harness bundle to the final binding for the harness bundle.
Keep holding lightly. As a result, when the binding machine 230 moves, the binding machine 230 binds the wires 10 while the handling clamps 510 handle the wires 10. This prevents the wires 10 from being entangled with each other. As described above, according to the present invention, it is possible to handle the harness having the connector connected to only one side.

FIG. 10 is a schematic configuration diagram of a harness manufacturing apparatus according to another embodiment of the present invention. The wire 10 is supplied from the electric wire supply device 800 to the harness manufacturing device 600 via the electric wire habit removing portion 810. This harness manufacturing apparatus 600 includes two rows of endless belts 612, 6
Each of the fourteen is provided with an electric wire conveying section 610 to which electric wire clamps 616 and 618 are fixed at equal intervals.
0, strip section 630, crimp section 640, insertion section 650
Are arranged.

The wire 10 supplied to the harness manufacturing apparatus 600 is measured and fed by the length measuring roller 622, and the vicinity of the tip of the wire 10 is clamped by the electric wire clamp 616 located in the length measuring unit 620. To be done. After that, the wire 10 is further fed by the length measuring roller 622, and when it reaches a predetermined length, the wire clamp 61
The rear end of the wire 10 is clamped by 8 and cut by the cutter 624.

In this way, the wire 10 cut in the length measuring section 620 and clamped by the electric wire clamps 616 and 618 in the vicinity of both ends thereof is next conveyed to the strip section 630. In the strip portion 630, the coating of the wire 10 is removed by the wire strips 632 and 634, and the core wire is exposed. The removed coating is sucked into the vacuums 636 and 638 and discharged.

The wire 10 whose core wires at both ends are exposed by the strip section 630 is then sent to the crimp section 640. In the crimping section 640, the contacts 50 supplied to the crimping section 640 are crimp-connected to the exposed core wires at both ends by a contact feeder (not shown). Then, this wire 10 is conveyed to the insertion part 650. Insertion part 6
A connector housing (not shown) is supplied to the connector 50 from connector feeders 652 and 654, and a contact housing chamber (not shown) of the connector housing.
Then, the contacts 50 crimped and connected to the wire 10 are sequentially inserted. By repeating the above operation and inserting a predetermined number of contacts 50 into the connector housing, the harness is completed. This harness is transported along the guide rails 200, and finally a predetermined number of harnesses are bundled and accumulated in the product tray 242. The embodiment is the same as that of the embodiment shown in FIG.

As described above, the present invention can also be applied to a harness manufacturing apparatus of the type in which the wire 10 and the contact 50 are connected by crimping.
