Description

[Detailed description of the invention] (Field of industrial application) This invention is a thin wire terminal processing machine that automatically pulls out a set length of wires from a bundle and strips off the insulation coating at the ends. The present invention relates to a device for supplying electric wires smoothly without twisting.

(Prior Art) When pulling out wires from a bundle of wires, it is necessary to remove the kinks caused by the curls. For this reason, conventionally, for example, a bundle of wires is set on a rotatable drum, and the wires are drawn out while the drum is rotated by pulling the wires.

(Problem to be solved by the invention) In the conventional method described above, due to repeated rotation and stopping of the drum as the wires are drawn out and stopped, the wire bundle becomes loose due to centrifugal force or inertia, or the drawn-out wires become bundled. It is not possible to supply the wires smoothly because the wires dig into the wires or the lead wires sag. This invention attempts to solve the above-mentioned conventional problems.

(Means for Solving the Problems) In this invention, in order to solve the above problems, the turntable 2 that holds the wound bundle W of the electric wires W is rotated by the motor M, the support 10 is erected, The part of the drawn-out electric wire w is hung around the mechanical synchronization sensor 16 or 23 provided on the support 10, and the mechanical synchronization sensor 16 or 23 senses the tension of the electric wire w above a predetermined value and connects it to the electric contact 18.
a or 26a, and is provided with an electrical synchronization contact 27a that closes in synchronization with the drawing operation of the thin wire end processing machine A that draws out and processes the electric wire w,
The synchronization contacts 18a, 27a, and 26a are interposed in series between the power source S and the motor M, and the rotation of the turntable 2 is controlled by the wire drawing operation of the thin wire end processor A and the wire w accompanying this. It was made to synchronize with the increase in tension.

(Function) When the wire drawing operation of the fine wire end processor A starts, the electrical synchronization contact 27a closes, and the wire w hooked to the mechanical synchronization sensor 16 or 23 is pulled, and its tension is detected by the sensor 16. or 23 senses, its contact 18a or 26a closes, thereby conducting between the power source S and the motor M, and the motor M
rotates, and the turntable 2 is rotationally driven.
As the turntable 2 rotates, the electric wire w is unwound and fed to the thin wire end processing machine A.

(Embodiment) A dish-shaped turntable 2 having a conical guide column 2a protruding from the center is mounted on a substrate 1 so as to be horizontally rotatable. As shown in FIG. 2, the turntable 2 is powered by a belt 3, a shaft 4, and a drive wheel 5 by a motor M located on the side thereof and provided on a base plate 1.
Rotationally driven through. Motor M, belt 3,
The shaft 4 and the drive wheel 5 are fixed to a mounting frame 6 rotatably provided on the base plate 1, and the mounting frame 6 is biased by a spring 7 so as to keep the drive wheel 5 in pressure contact with the outer periphery of the turntable 2 at all times. has been done.

An annular wire receiving tray 8 is fitted onto the turntable 2 in an overlapping manner. As shown in FIG. 3, on the inside of the saucer 8, a plurality of claws 9 are protruded concentrically to insert into the wire bundle W and hold it while preventing it from collapsing. The saucer 8 is detachable from the turntable 2.

A support 10 is erected on the substrate 1. The strut 10 is bent so that its upper part extends above the turntable 2, and its height can be changed by adjusting the height adjustment mechanism 10a according to the hardness and thickness of the electric wire.

A support frame 13 that supports the lower end of the support rod 11 via a spring 12 is attached to the middle of the support column 10. An elongated hole 13a is formed in the support frame 13, into which an adjustment bolt 14 is movably inserted, and the adjustment bolt 14 is screwed into a spring hook nut 15 that locks one end of the spring 12, so that the support frame 13 The position is fixed and can be adjusted freely.

A first sensor 16 for mechanical synchronization is attached midway up and above the column 10. The sensor 16 consists of a support rod 11, a pair of parallel frames 17 fixed to the support column 10, and a limit switch 18 attached inside the frames. Said support rod 1
1 is pivotally attached to a frame 17 by a pivot 19, and a limit switch 18 is provided above the pivot portion. Then, the end of the electric wire w is hung on the tip of the support rod 11, and the electric wire w is pulled to the support rod 1.
1 rotates counterclockwise around a pivot 19, the limit switch 18 is pushed by the pivot 19 and closes its contact 18a. The tip of the support rod 11 may be bent as shown to form a hook, or a pulley (not shown) for wrapping the electric wire w may be attached thereto.

A mounting plate 20 is fixed to the tip of the support 10, and feed rollers 21 and 22 that sandwich the electric wire w are rotatably attached to the mounting plate 20. A second sensor 23 for mechanical synchronization is provided at the bottom of the mounting plate 20. As shown in FIG. 6, the second sensor 23 includes a second support rod 24 pivotally attached to the mounting plate 20, a spring 25 stretched between the lower end of the support rod 24 and the mounting plate 20, and a support rod 24 that is connected to the mounting plate 20. A limit switch 26 closes its contact 26a by counterclockwise rotation of the rod 24. An electric wire w is hung on the tip of the support rod 24, and the support rod 24 can be rotated by being pulled by the electric wire w. A pulley (not shown) can also be attached to the tip of the support rod 24.

The tip end of the electric wire w is introduced into a known thin wire end processing machine A that pulls out the electric wire w by a preset length, cuts it, and peels off the coating from the end.

As shown in FIG. 7, between the motor M and the power source S, the contacts 18a and 26a of the limit switches 18 and 26 of the first sensor and the second sensor, and
A control circuit is constructed by connecting in series a contact 27a of an electrical synchronization sensor that responds to the drawing operation of the thin wire end processor A and a main switch SW. In FIG. 7, L ₁ is a power indicator light, and L ₂ is a sensor operation indicator light.

This wire supply device is used in the following manner. Put the coiled bundle W of electric wire into the tray 8, fit the tray 8 into the turntable 2, pull up one end of the electric wire w, and first connect the support rod 1 of the first sensor 16 along the way.

When the thin wire end processing machine A starts drawing out the electric wire w, the electrical synchronization contact 27a closes. Electric wire lol
, the first and second sensors 16, 2
The support rods 11 and 24 of No. 3 are pulled and rotated counterclockwise in the figure, causing the limit switches 18 and
When the contacts 18a and 26a of 26 are closed, the motor M
rotates, causing the saucer 8 to rotate together with the turntable 2. Therefore, the wire bundle W rotates in accordance with the withdrawal of the wires w, and removes the curling of the wires w. The hardness of electric wires varies depending on their thickness. Furthermore, the hardness of the wire coating changes slightly depending on the outside temperature. Due to these changes, the tensile force applied to the support rod 11 of the first sensor 16 changes, so the position of the adjustment bolt 14 is determined to correspond to this change.

The invention is not limited to the illustrated embodiment. For example, the wire bundle W can be placed directly on the turntable, and one of the mechanical synchronization sensors can be omitted. The electrical synchronization contacts may also take the form of relays or other forms having the same effect.

(Effect of the invention) In this invention, the wire bundle W can be rotated electrically in synchronization with the operation of the thin wire end processing machine A and mechanically synchronized with the tensile force of the wire w. The wire w can be smoothly supplied to the thin wire end processing machine A while removing curls in the wire w without causing sag, digging into the wire bundle W, or deformation of the wire bundle W. Further, in this case, there is an effect that a long distance to the thin wire end processing machine A is not required, and work can be performed in a narrow space.
