One end of the brake band 29 is fixed to the frame 11 as shown in FIG. 1, and the other end is connected to the frame 11 via a spring 31. The required braking force is applied to the winding drum 25 by the tension of the spring 31. This is the case.

33 is a cam integrally attached to the tip of the drive shaft 21,
The cam 33 is located in a concave portion 35 formed at the center of the front surface of the winding drum 25.

37 is a striated body wound around the winding drum 25, such as a tape wire,
39 is an insertion port at the beginning of the winding of the tape wire 37 formed on the winding drum 25, and 41 is a winding drum such that the tip enters and exits the insertion port 39.
A clamp piece 43 incorporated in 25 is a rubber plate embedded in the insertion port 39 at a position facing the tip of the clamp piece 41.

The winding drum 25 is composed of two members 25A and 25B as shown in FIG. 7 to incorporate the clamp piece 41 therein. A hole 45 for accommodating the clamp piece 41 is formed in one member 25A, and a hole 47 through which the above-described insertion port 39 and the tip of the clamp piece 41 penetrate is formed in the other member 25B. These two members 25A and 25B are integrated by bolts 49 as shown in FIGS. In the hole 45 of the one member 25A, a coil spring 51 is housed in a compressed state together with a clamp piece 41, and the clamp piece 41 receives the repulsive force of the coil spring 51 at the rear end flange and always receives the center of the winding drum 25. Is being urged towards.

On the outer periphery of the cam 33, a cam surface a for slidingly moving the clamp piece 41 by slidingly contacting the rear end face of the clamp piece 41, and two abutting surfaces b and c substantially orthogonal to each other are formed. An adjusting screw 53 for regulating the rotation angle of the cam 33 in the concave portion 35 is provided on the winding drum 25.
・ 55 are provided. One of the adjusting screws 53 is, for example, as shown in FIG. 5, the cam 33 rotates forward with respect to the winding drum 25 (clockwise in the figure) in a state where the winding start end of the tape wire is not inserted into the insertion port 39. When the clamp piece 41 is advanced (raised) to a position where the tip of the clamp piece 41 contacts the rubber plate 43, it is adjusted so as to contact one of the abutting surfaces b of the cam 33. When the cam 33 rotates in the reverse direction (counterclockwise in the figure) with respect to the winding drum 25 and separates from the clamp piece 41, for example, as shown in FIG. Is adjusted so as to abut against the abutting surface c. Therefore, if the cam 33 is further rotated forward from the state shown in FIG. 5, the winding drum 25 rotates forward together with the cam 33, and if the cam 33 is further rotated reversely from the state shown in FIG. It will rotate in reverse.

In addition, an insertion guide 61 is attached to the frame 11 as shown in FIG. 1 to facilitate the insertion of the tape wire 37 into the insertion opening 39 at the winding start end.

Further, in order to prevent the tape wire 37 wound around the winding drum 25 from falling apart, a holding roll 63 is provided as shown in FIG. The holding roll 63 is supported by the tip of an arm 67 that rotates about a fixed shaft 65, and a spring 69
Thereby, it is pressed against the peripheral surface of the winding drum 25.

 Next, the operation of this device will be described.

When the winding start end of the tape wire 37 is inserted into the insertion port 39 of the winding drum 25, the winding drum 25 and the cam 33 are in a positional relationship as shown in FIG. In other words, the tip of the clamp piece 41 is
It does not protrude inside. In this state, the drive shaft 21 is rotated forward (clockwise in the figure) after the winding start end of the tape wire 37 is inserted all the way into the insertion port 39, and the winding band 25 is braked by the brake band 29 and the brake wheel 27. At first, only the cam 33 rotates forward to move the clamp piece 41 forward (push up). When the tip of the clamp piece 41 moves forward until the tape wire 37 abuts against the rubber plate 43 as shown in FIG. 3, the clamp piece 41 cannot move forward any more, and the tape 33 is pressed between the rubber plate 43 by the pressing force of the cam 33. The electric wire 37 is clamped. When the cam 33 further rotates, the rotational force is applied to the clamp piece 41, the tape wire 37,
The power is transmitted to the winding drum 25 via the rubber plate 43, and the winding drum 25 starts rotating against the braking force. This allows the tape wire 37 to be wound
It will be wound up in 25.

The clamping force at the winding start end of the tape wire 37 can be adjusted by adjusting the braking force, that is, the tension of the brake band 29.

When the tape wire 37 cut to a predetermined length in the previous step is wound up to the end, the rotation of the drive shaft 21 is stopped, and then the drive shaft 21 is reversely rotated by about 90 °. Then, the winding drum 25 does not rotate because the braking force is applied, and only the cam 33 rotates in the reverse direction. Therefore, the clamp piece 21 retreats by the repulsive force of the coil spring 51 and returns to the state shown in FIG. The clamp at the winding start end of the electric wire 37 is released. As a result, the coiled tape wire can be removed from the winding drum 25.

The above is one embodiment of the present invention, and the present invention is not limited to this. For example, as shown in FIG. 8, the forward and backward movement of the clamp piece 41 can be performed by a crank mechanism 71 attached to the drive shaft 21. In FIG. 8, the same parts as those of the above embodiment are denoted by the same reference numerals, and the description of the other parts will be omitted.

In addition to the band brake, a disc brake, an electromagnetic brake, or the like can be used as the winding drum braking means.

Further, the present invention can be applied to winding of a wire other than the tape wire.

By simply rotating the drive shaft in the reverse direction, the clamp at the start end of the winding of the filament can be released. Therefore, the structure of the device is extremely simplified, cost is reduced, failures are reduced, and reliability for automatic operation is increased.
