It is for continuously separating only the release paper 6 from the wound diode roll 1.

As shown in FIG. 2, one side of the base plate 10 is equipped with a feed roller 12 capable of inserting and supplying a diode roll 1, which is supplied to the bolt 14. It is supported by the bracket 16 that is fixed by. Further, in front of the feed roller 12, a release paper winding means for continuously winding the release paper 6 separated from the diode roll 1 inserted into the supply roller 12 is provided. The release paper winding means is composed of a winding roller 20, the winding roller 20 is a bracket (24A) fixed to the base plate 10 by the bolt 22, similar to the supply roller 20, ( 24B) is installed on the upper side.

On the other hand, a rotation means for rotating in the direction of the arrow A of the take-up roller 20 is connected to the end of the rotation shaft 26 of the take-up roller 20, the rotation means is composed of a torque motor (30).

As can be seen in FIG. 2, between the winding roller 20 and the torque motor 30, when the motor 30 is stopped (here, the stopped state of the motor is completely stopped or the release paper 6 is removed). Means that the motor is overloaded and the motor is overloaded between the feed roller 12 and the winding roller 20). The reverse rotation preventing means 40 is mounted so that the release paper 6 being wound in the first direction (that is, the B-direction) is not unwound again by the winding roller 20 in the second direction (that is, the C-direction). .

The reverse rotation preventing means 40 is on the outer circumferential surface of the shaft coupling 42 and the shaft coupling 42 for connecting the rotary shaft 26 of the take-up roller 20 and the rotary shaft 32 of the torque motor 30. And projections 42A mounted at predetermined angles. The projection 42A is mounted inclined at a predetermined angle with respect to the normal of the shaft coupling 42 on the outer circumferential surface of the shaft coupling 42 as shown in FIG. 4, and the projection 42A is a suitable method. It is mounted on the outer circumferential surface of the shaft coupling 42 (for example by bolting or welding) and effectively prevents the reverse rotation of the motor as described in detail later.

In addition, the reverse rotation preventing means 40 is located at a predetermined distance from the projection 42A mounted on the shaft coupling 42 so that the winding roller 20 does not reversely rotate in the C-direction when the torque motor 30 is stopped. And a reverse rotation suppressing mechanism 46 mounted on the bracket 44 to prevent it.

As can be seen in FIGS. 3 and 4, the reverse rotation inhibiting mechanism 46 includes a support plate 400 fixed to at least one screw 48 on the bracket 44, and the support plate 400. ), A stopper fixing plate 402 fixed to at least one screw 50, a stopper 404 rotatably mounted below the support plate 400, and a spring providing elasticity to the stopper 404. 406).

At one end of the support plate 400, a projection 400B having a spring 406 is provided with a locking piece 400A, and at its other end, a screw hole fixed to the bracket 44 by a screw 48. 400C is formed. In addition, the support plate 400 is provided with a hole 400D of the screw 50 for fastening the stopper fixing plate 402.

The stopper fixing plate 402 is fastened by the screw 50 on the support plate 400, and at least one screw hole 402A for inserting the screw 50 is formed. Further, two holes 402B are formed in the downward protrusion of the stopper fixing plate 402 to which the rotation shaft 404A of the stopper 404 can be fitted.

In the stopper 404, two rotary shafts 404A inserted into the rotary shaft hole 402B of the stopper fixing plate 402 are integrally formed at the end thereof, and the end of the spring 406 is fixed to the central portion of the stopper 404. The spring engaging piece 404B is formed.

In the assembled state of the diode release paper removing device according to the present invention configured as described above, the bracket 44 is fixed on the base plate 10 by a suitable method, such as bolting, and the torque motor 30 on one side thereof. Mount the, but inserts the rotation shaft 32 of the torque motor 30 through a hole (not shown) formed in the bracket 44. Then, the rotary shaft 26 of the take-up roller 20 is inserted through a hole (not shown) formed in the bracket 44, and the rotary shaft 32 of the torque motor 30 and the rotary shaft 26 of the take-up roller 20 are formed. ) Is firmly connected to each other by the shaft coupling (42).

In addition, as shown in FIG. 4, the projection 42A is fixedly installed on the outer circumference of the shaft coupling 42, and the support plate 400 constituting the reverse rotation suppressing mechanism 46 is provided at the center of the bracket 44. As shown in FIG. It is fixed by this screw 48. The stopper fixing plate 402 is fixed to the support plate 400 as a screw 50, and the spring 406 is inserted into the rotating shaft hole 402B of the stopper fixing plate 402 by inserting the rotating shaft 404A of the stopper 404. Assembling process is completed by connecting one end of the end to the spring engaging piece 400A of the support plate 400, and the other end of the spring 406 to the spring engaging piece 404B of the stopper 404.

When the torque motor 30 is rotated in the direction of the arrow A during assembly of the flyback transformer in the assembled state, the shaft coupling 42 connected to the rotation shaft 32 of the motor is also rotated in the same direction.

When the shaft coupling 42 is rotated, the projection 42A fixed on its outer circumferential surface is also rotated in the direction of the arrow A. As shown in detail in FIG. 4, the end of the projection 42A is a stopper ( 404 is lowered while pressing the end.

When the lowering of the protrusion 42A as the rotation of the shaft coupling 42 proceeds gradually to reach the position shown by the dotted line in FIG. 4, the stopper 404 is separated from the protrusion 42A to the spring 406. To return to the solid line position. By the way, the projection 400B formed at the lower end of the support plate 400 is to prevent the stopper 404 from further progressing upward.

When the shaft coupling 42 is rotated in the clockwise direction A, the rotary shaft 26 of the winding roller 20 connected thereto is also rotated in the clockwise direction, so that the release paper 6 is released from the supply roller 12 and the arrow B It proceeds in the direction of) and is wound on the take-up roller 20, the diode 2 is supplied to a diode supply device (not shown) to be used in the manufacture of the flyback transformer.

However, when the motor 30 is temporarily stopped or the release paper 6 is very tight between the feed roller 12 and the take-up roller 20 and the motor 30 is overloaded, the motor 30 is a torque motor. Because of this may be rotated in the opposite direction of the arrow (A), when the reverse rotation of the motor 30 may be a problem that the release paper 6 wound so far is released in the C-direction.

To this end, in the present invention, a reverse rotation preventing means has been devised. Even if the motor 30 rotates in reverse as shown in FIG. 4, the projection 42A provided on the outer circumferential surface of the shaft coupling 42 is formed of the stopper 404. Since the shaft coupling 42 is no longer rotated in the opposite direction to the arrow A as it is caught by the lower end, the wound release paper 6 is not released in the C-direction of FIG. In this case, as shown in FIG. 4, the projection 42A can prevent the reverse rotation of the motor more efficiently because its end portion is inclined upward with respect to the outer circumferential surface of the shaft coupling 42.

As described above, according to the diode release paper removing apparatus according to the present invention, there is an effect that the work efficiency can be increased by automatically separating the release paper from the diode roll by using the rotational force of the motor.
