Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thin film cutting device, and more particularly to a device that cuts brittle thin films supplied in strips into predetermined shapes and then stores them in a stacked manner.

Conventionally, there have been two types of cutting devices for uncured, brittle sheets such as ceramic green sheets: (i) those using punches and dies, and (ii) those using blades and T-shapes.

In the former method (i), high dimensional accuracy of the cut film or the punching die was required to obtain a film with a good cut surface.

For this reason, the number of times the punching die must be ground increases, and when the thin film is fed onto the die, it tends to bend on the die, resulting in poor dimensional accuracy of the cut film, which also causes problems in feeding the film.

Even in the case of the latter (ii), since a die is used for the lower part of the blade, the same problem as in the case of the punching die occurs.

In addition, in order to take out the cut membrane, the cut membrane is first moved to the stage of the method, and then the membrane is taken out in a certain size and stored in a predetermined position, but if the membrane is thin or brittle, especially It had the disadvantage of causing damage to the

In addition, with conventional thin films, static electricity is likely to be generated when the film is moved or cut, which obstructs feeding, cutting, and storage operations, or causes the films to stick together, significantly impeding workability in subsequent processes.

An object of the present invention is to provide a thin film cutting and storage device having high quality and high workability.

According to the present invention, there is obtained a thin film cutting device characterized in that a member mounted on an elastic support base for cutting the thin film into a predetermined shape is provided with means for attaching and detaching the cut thin film.

In particular, according to the present invention, a belt conveyor with elasticity,
A cutting blade block installed on the upper part of the belt conveyor has a cutting blade on its outer peripheral edge and a suction hole, an exhaust hole, and a static elimination electrode hole on the lower surface, and a cutting membrane that moves back and forth to the position of this cutting blade block. A thin film cutting/storage device characterized by being provided with a take-out plate is obtained.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows an external perspective view of an embodiment of the present invention, and FIG. 2 shows a sectional view of a cutting blade block.

The structure of the cutting block 1 is as follows.

A single-edged cutting blade 2 is attached to four sides of the outer peripheral surface of a cutting blade block 1 so that the corners are aligned and there is no gap.

The static eliminating component 4 is fitted into the center of the cutting blade block 1 so that the static eliminating electrode 5 is located on the lower surface.

The mold removal component 4 has a through hole 41, and a tube (not shown) is connected to the upper part through which negative and positive air pressure is output by switching the adsorption/exhaust valve.

A pad 3 is attached to the lower surface of the cutting blade block 1, with a hole 31 about the area directly below the static elimination electrode 5 and a hole 32 about 1 to 2 mm in diameter on the other surface.

As shown in Fig. 1, the external structure of the main part of the device consists of a drive boot connected to a drive motor 17 that rotates the belt conveyor.
J-10, driven boo' J-11. Belt tension relief 1
2 and the rubber belt 18 constitute a belt conveyor.

The die holder 19 is arranged at a position where the belt slides on the upper surface of the die holder 19.

The upper surface of the cutting blade block 1 is attached to the lower surface of the block holder 8.

The block holder 8 is passed through the guide 9, and the cutting blade block 1 is installed in a suspended state in the space above the belt conveyor.

Fixing plate 7 is fixed to the upper end of guide 9.

The press cylinder 6 body is attached to the fixed plate 7 by connecting the piston and the block holder 8.

The piston of the cut film take-out cylinder 16 and the cut film take-out plate 14 are connected.

The cutting membrane storage case 15 is removably set on the cutting membrane take-out plate 14.

The cutting film take-out cylinder 16 is operated to position the film storage case 15 directly below the cutting blade block 1 when the piston is at the front dead center.

Next, the operation of this device will be explained.

First, the drive motor 17 is rotated, and the belt-shaped thin film 13 on the rubber belt 18 is fed to below the cutting block 1 and the cutting operation begins.

In order to adsorb the membrane 13a cut out in cutting 1 (hereinafter referred to as the cutting membrane) during the cutting operation, positive pressure is applied to the tube of the static elimination component 4 attached to the cutting blade block 1 at the same time as the press cylinder 6 is lowered. Then, the strip-shaped thin film 13 is cut at the bottom dead center of the press, and the cutting blade block 1 is raised while the cutting film 13a is adsorbed to the lower surface of the cutting blade block 1, and returned to the top dead center.

to just below the cutting blade block 1 with the cutting film adsorbed,
Place the cutting membrane storage case 15 and operate the cutting membrane take-out plate 14 and the cutting membrane take-out cylinder 16.
There, the tube that had been set to the above-mentioned positive pressure is switched to positive pressure, and the air containing the static elimination ions produced by the static elimination electrode 5 of the static elimination component 4 is blown out, and the cutting membrane 13a is blown into the cutting membrane storage case 15. Drop it.

Then, lower the cut membrane removal plate 14 to its original position,
One cycle of steps is completed.

When this process is performed continuously, the cut films 13a whose charges have been removed one after another are stacked and stored in the cut film storage case 15.

Incidentally, the cut scraps 20 ride on the rubber belt 18,
If the scrap pulley 21 is continuously rotated by the scrap feed motor 22 to apply a tensile force to the scrap 20, the scrap 20 will be pulled out of the center of the strip-shaped thin film 13 and become weak. It also has the advantage of not bending or shifting sideways.

As described above, according to the thin film cutting and storage device of the present invention, since the film is fed together with the belt on the flat surface of the belt before cutting, even weak and brittle thin films can be easily fed, and the cutting blade and rubber can be easily fed. The dimensional accuracy of the cut membrane and the condition of the cut surface are good because the cut is made between the two ends.

Furthermore, since the cutting edge is absorbed into the flexible rubber material during cutting, there is less wear on the cutting edge.

Furthermore, the method of taking out and storing the material using the device of the present invention has great effects such as eliminating the static electricity without damaging the cutting film.
