It comprises a return means (128,129) for maintaining the position.

The return means is a spring fixed portion 129 and the braid coupling portion 124 is fixed to the rotating cylinder 60, one side of the coupling is fixed and the other side is fixed to the spring fixing portion 129 (128).

On the other hand, in the braid rotary cutting device according to the present invention, the moving shelf 10, the shelf moving means 20, the left and right fixing parts 30A, 30B, guide rollers 40A, 40B, 40C, rotation The upper part including the cylinder 60, the trumpet-shaped cylinder 70, the trumpet-shaped cylindrical moving means, and the rotating braid part is sealed by, for example, a high-strength plastic made of a transparent material except for a portion through which the pipe to be cut 1 passes. It is desirable to have.

The operation of the braided rotary cutting device according to the preferred embodiment of the present invention configured as described above will be described. The case where the present cutting device is used to cut the plastic pipe that is injected from the plastic pipe injection device into a predetermined length unit will be described as an example.

First, the control means (not shown) drives the left and right fixing parts 30A and 30B when a sensing signal transmitted from the plastic injection device (that is, a signal transmitted by sensing the length of the pipe that is injected) is input. To control the pipe 1 and simultaneously drive the shelf moving means 20 so that the shelf 10 is in the injection direction of the pipe 1 at the same speed as the pipe 1 is ejected from the injection device. Control to proceed.

At the same time, the motor 50 is driven to control the rotating cylinder 60 to rotate at a high speed in a direction perpendicular to the traveling direction of the pipe 1, and also the fallopian cylinder moving means 90 is driven to the fallopian tube 70 ) Moves forward in the same direction as the traveling direction of the pipe (1).

Accordingly, since the moving shelf 10 moves in the state in which the pipe 1 is fixed by the left and right fixing parts 30A and 30B, the left and right fixing parts 30A and 30B mounted on the moving shelf 10 are moved. ), The guide rollers 40A, 40B, 40C, the rotating cylinder 60, the trumpet cylinder 70, and the trumpet cylindrical moving means 90 move at the same speed as the forward speed of the pipe 1.

At the same time, since the rotating cylinder 60 rotates at a high speed and the fallopian tube cylinder 70 moves forward, the cam 122 rotates and is located outside the large diameter on the inner surface of the fallopian tube cylinder 70 as shown in FIGS. 5 and 7. As the fallopian tube 70 gradually moves forward, the braid 120 is pushed toward the center of the pipe 1 as the inner diameter of the fallopian tube 70 moves toward the smaller diameter. Accordingly, the pipe 1 is cut by the braid 120.

Then, the control means (not shown) drives the left and right fixing parts 30A and 30B to release the fixing of the pipe 1, for example, in response to the signal input from the limit switch, and at the same time the shelf By controlling the driving means 20 to reverse in the direction opposite to the traveling direction of the pipe 1, and at the same time to control the driving of the motor 50 to stop the rotation of the rotating cylinder 60, and at the same time The fallopian tube cylindrical moving means 90 is driven to control the fallopian tube cylinder 70 to reverse in a direction opposite to the traveling direction of the pipe 1.

Subsequently, the control means (not shown) stops driving of the shelf moving means 20 and the fallopian tube cylindrical means 90 according to a signal input from a limit switch, for example. 70) is in the initial position.

By repeating the above process, the plastic pipe injected from the plastic pipe injection device is cut to a predetermined length.

As described above, according to the present invention, since the saw blade is not generated because of the use of the rotating braid, it is possible to maintain the cleanliness of the work space and reduce the waste disposal cost.

In addition, according to the present invention, the use of a rotating braid can significantly reduce the generation of various harmful components such as dioxins due to friction with plastic pipes, compared to conventional saw blades, providing a healthy working environment and an environment such as dioxins. Contamination can be significantly reduced.

In addition, according to the present invention, since the rotary blade is used, the perpendicularity of the cutting plane with respect to the longitudinal direction of the pipe is superior to that of the conventional saw blade.

On the other hand, the present invention is not limited to the above specific embodiments, but can be modified and modified in various ways without departing from the gist of the present invention. It will be obvious that such modifications and variations are included in the appended claims.
