Abstract

PROBLEM TO BE SOLVED: To wind a waste cut wire housed in a container installed on a turntable in a multilayer vortex so as to increase a volume by several times by attaching a speed sensor to a feed roller. SOLUTION: A waste cut wire 1 is held between the tension roller 2 of a feeding device and a feed roller 4 having a speed sensor 3 incorporated to be rotated in press contact and discharged and drooped by gravity from a wire cut discharge machine main body 5. The waste cut wire 1 is housed in a container 10 installed on a turntable 9 supported and rotated on the output shaft 8 of a motor 7 controlled by a controller 6 based on the information of the speed sensor 3. Following the housing, a rotating speed is changed and the waste cut wire 1 is wound in a multilayer vortex. By providing a disturbed winding preventing shaft around the container 10, efficient winding is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding a waste cut wire in a wire-cut electric discharge machine.

[0002]

2. Description of the Related Art Conventionally, a waste cut wire of a wire cut electric discharge machine has a waste cut wire winding device incorporated on the machine, and is wound by a bobbin or the like. It is fed out of the machine body and pushed into the container due to the rigidity and straightness of the waste cut wire. In addition, it is cut to a fixed size by a cutting device and freely dropped on a container to compress the volume of the entanglement.

[0003]

Disadvantages of the prior art However, the winding of the bobbin in the automatic wiring device must be pre-tensioned so that the waste cut wire does not slip even when the bobbin rotates, but it cannot be done unattended. In the method of pushing into a container, the volume entangled with the bobbin before processing becomes several tens times larger than the volume of the winding wound on the bobbin, the space of the dedicated container becomes large, and when transferring to another container, There is a danger of being injured because the surface roughened by the discharge of the waste cut wire has a thread saw shape, and cannot be easily performed when compressed. In addition, the cutting device cannot be used unless the blade to be cut is worn or replaced or polished. Further, the waste cut wire after cutting has a very high possibility of sticking to a human body at the time of transfer to a container.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve such disadvantages of the conventional means, and enables unattended operation of a wire-cut electric discharge machine and increases the volume of a waste cut wire by several times. In addition, it can be processed without touching it when transferring it to another container, and there is no danger of injury. It is intended to provide a device.

[0005]

According to the present invention, a waste cut wire is discharged from a feeding device incorporating a speed sensor, and the cut wire is dropped by its own weight. The waste cut wire is installed on a turntable provided with a mechanism controlled and rotated by a controller based on sensor information. This is a waste cut wire take-up device that is put into a container and the number of rotations changes to form a multilayer spiral.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiment shown in FIG. 1. A waste cut wire 1 is sandwiched between a tension roller 2 of a feeding device and a feeding roller 4 incorporating a speed sensor 3 which rotates by pressing. It is thrown down from the main body 5 by its own weight and is thrown into a container 10 installed on a turntable 9 which rotates on an output shaft 8 of a motor 7 controlled by a controller 6 based on information from a speed sensor 3, and the number of rotations changes. The waste cut wire 1 is a multilayer spiral.

[0007] By providing a winding prevention shaft at the center of the container 10, the winding can be performed more efficiently.

[0008]

The present invention is embodied as described above. To set this, the speed sensor 3 is attached to the feeding roller 4 of the wire-cut electric discharge machine body and wound around the lower part of the discharge port of the waste cut wire. Install the take-off device and turn on the power.

[0009]

As described above, according to the present invention, the speed sensor 3 is attached to the feeding roller 4 of the basic mechanism of the wire cut electric discharge machining.
In any state of the wire speed, the controller 6 controls the motor 7 so that the waste cut wire 1 put in the container 10 installed on the turntable 9 which rotates while being supported on the output shaft 8 is attached. It is wound up in a multi-layer spiral, and its volume is several times larger, and even if it is used continuously for a long time, the waste cut wire container is about several tenths of the conventional one, and it also saves space in the transport and storage of industrial waste. .

If the container 10 is lifted and tilted, the waste cut wire can be discharged, and when the container 10 is transferred to another container, the waste cut wire can be treated without touching the waste cut wire. Can reduce operation downtime.

[0011] In addition, since parts such as blades which are consumed in a short period of time are not used for the entire apparatus, unattended operation can be performed day and night without management of replacement and the like, and running costs are low only because of the cost of electric power for driving the motor.
