Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering device for binding a bundle of electric wires in a line in an automatic bundle gathering machine with a string.

[0002]

2. Description of the Related Art The configuration of a conventional automatic bundling line will be described with reference to the drawings. In FIG. 3 which is a plan view of the entire automatic winding line and FIG. 4 which is a side view, first, the electric wire is automatically wound into an annular bundle 2 by the automatic winding machine (bundling machine) 1 on the right side. . This bundle 2 of electric wires is pushed out to the center position of the vertical binding machine 3 on the left side by a bundle feeding device composed of two expandable and contractable arms 6 provided on both sides of the bundling machine 1, and here, it is vertically moved by a string. Unity is done. Next, in order to bundle the wire bundle 2 in the lateral direction, the centering arm 7 is moved to the rotary table 8. As shown in the plan view of the rotary table portion of FIG. 2, the centering arm 7 is moved in the left-right direction along a guide arm provided in parallel with the vertical / horizontal binding machines 3 and 4. 7
The two claws 7a at the tip of the hook are hooked on the bundle 2 of electric wires, and the centering arm moving motor 12 shown in the side view of FIG.
The chain 11 driven by is moved from the state indicated by the broken line to the state indicated by the solid line to the left side indicated by the arrow, and is placed at the center position of the rotary table 8.

At this time, the stop position of the centering arm 7 moved by the chain 11 is the rotary table 8.
The limit switch 9 is provided so as to be movable left and right by a guide arm 10 installed parallel to the side surface of the. That is, when the end of the centering arm 7 touches the limit switch 9, the driving of the centering arm drive motor 12 is stopped and positioning is performed.

By the way, the outer diameter of the bundle 2 of electric wires formed by the automatic bundling machine 1 differs depending on the product type, and the centering arm 7 is moved to the center position of the rotary table 8 for each different outer diameter. The position of the limit switch 9 that is automatically stopped is adjusted by the operator's hand according to the product type, and the center position of the bundle 2 of electric wires is set to the center position of the rotary table 8. That is, in the vertical binding machine 3, since the bundle 2 of electric wires is sent from the automatic binding machine 1 in a state where the center position in the vertical direction is set, it is not necessary to perform centering, and the center of the vertical binding machine 3 is kept as it is. Vertical stringing is performed at the position. Next, turning is performed by moving the vertically bundled wire bundle 2 to the turntable 8 and rotating the bundle 2 by 90 degrees in order to perform the horizontal strapping. At this time, although the centering in the vertical direction is performed, the center position in the horizontal direction is moved only by turning the rotary table 8 90 degrees. Then, the bundle 2 of electric wires is driven by the centering arm moving motor 12 and the claw portion 7a of the centering arm 7 is hooked and moved again via the chain 11 to be moved to the horizontal binding machine 4. At this time, it is necessary to move it to the position of the horizontal binding machine 4 with the lateral center position being taken out. Therefore, in order to position the bundle 2 of electric wires at the center position of the rotary table 8, the limit switch 9 determines the stop position. Then, the bundle 2 of electric wires is turned 90 degrees on the rotary table 8 to perform centering in the horizontal direction and is moved to the horizontal binding machine 4, and after binding with a horizontal string, it is hung on the vertical and horizontal crosshairs. The bundle of electric wires 2 was moved to the left side conveyor belt 5 again by the centering arm 7 and carried out.

As described above, the outer diameter of the bundle 2 of electric wires formed by the automatic bundle takeer 1 varies depending on the product type, and the centering arm 7 moves the bundle 2 of electric wires for each different product type. The position of the limit switch 9 for automatically stopping the electric wire is finely adjusted by the operator's hand so that the center position of the bundle 2 of electric wires is centered on the center position of the rotary table 8, and this is centered on the horizontal binding machine 4. It was moved by the arm 7 to carry out lateral binding. That is, a bundle of electric wires 2
Each time the outer diameter dimension of the device changes (every product type changes), the limit switch 9 is finely adjusted to perform the centering of the stop position of the bundle 2 of electric wires on the rotary table 8.

[0006]

As described above, in the conventional automatic bundling line, the outer diameter of the bundle of electric wires on the rotary table changes every time the product type changes, and the stop position of the centering arm is changed each time. I had to make fine adjustments with the limit switches.

The object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a laser reflection system in which the inside of the bundle of electric wires is provided above and below the rotary table regardless of the change in the outer diameter of the bundle of electric wires due to the difference in product type. Detecting using a switch and a reflector, centering is performed by driving the centering arm 7 for the amount of movement from this point to the center position (d / 2) for the time set by the timer, and the fine limit switch It is an object of the present invention to provide a positioning device for an automatic wire bundle picker for electric wires that does not require adjustment.
