Description

DETAILED DESCRIPTION OF THE INVENTION The present invention cuts thin films made of brittle and malleable materials, such as porcelain materials or plastic materials that are half-dried before being fed, into a fixed size, and also eliminates the cuts that occur during cutting. This relates to a device that removes powder while stacking it in a predetermined container in a clean state and taking it out.

Conventionally, this type of cutting equipment automatically and accurately performs the work of applying feed to the thin film to be cut, cutting the thin film, stacking the cut thin film in a designated container, and taking it out in a clean state. There is no continuous cutting, but a simple cutting jig consisting of a punch and die is used, and each time the worker cuts each piece, he uses tweezers to take it out of the cutting jig and reach the required number of pieces. The common method was to stack them in containers up to the maximum.

In such conventional methods, the production is inefficient, the yield is low, and the products are expensive because they are all done manually by workers. In addition, methods such as blowing compressed air onto the cut portion have been used to remove chips generated during cutting, but the chips scatter and adhere to the product, causing a reduction in quality. Furthermore, even if the thin film is manipulated during cutting, the cutting operation continues as is, resulting in various drawbacks such as the inability to obtain products with good dimensional accuracy. SUMMARY OF THE INVENTION An object of the present invention is to provide a thin film cutting device which eliminates the above-mentioned drawbacks, allows thin films to be stacked and taken out after cutting with high precision, and which can be easily handled by an operator.

According to the present invention, an apparatus for cutting brittle and flexible thin films has a plurality of vacuum suction holes on one end surface (hereinafter referred to as the lower end surface), and has a plurality of vacuum suction holes on the same axis as the lower end surface. A punch with a constant cross-sectional shape and a driving source connected to the other end surface (hereinafter referred to as the upper end surface) is arranged facing vertically downward at a fixed distance from the lower end surface of the punch, and is arranged on a sliding surface with the punch. a die having an air suction space; a wrinkle holder for the thin film that is slidable on the outer circumferential surface of the punch and whose tip protrudes slightly from the lower end surface of the punch and has a dust suction space at the lower inner surface; a take-out container disposed facing the punch in a downward direction, a thin film feeding section disposed near the punch and the die, a vacuum suction hole of the punch, an air intake space of the die, and a dust suction space of the wrinkle presser. a vacuum source connected to the die, a compressed air source connected to the intake space of the die, a mechanism control unit that controls the operation of the punch and the thin film feeding unit, and a mechanism control unit connected to the vacuum source, the compressed air source, and the mechanism control unit. There is obtained a thin film cutting device characterized in that it is configured with a central control section that controls the entire operation.

Next, an embodiment of the present invention will be described with reference to the drawings.

Figure c is a cross-sectional view showing the state after cutting, Figure d is a cross-sectional view showing the state after stacking, and Figure e is a cross-sectional view showing the state after thin film feeding.

In the figure, the film is a thin film, and 11 is a punch having a plurality of vacuum suction holes 13 on the lower end surface 12, and the upper end surface 14 is connected to a driving source 15 for vertical movement.

In order to cut the thin film 10 with a die, 17 is arranged below the punch 11 facing each other at a constant interval L, and on the sliding surface 18 with the punch 11, chips 19 of the thin film 10 generated during cutting are placed.
The intake space 2 is used to blow out compressed air 20 that vacuum removes the thin film 101 and gives a buoyancy force to the thin film 101 when feeding the thin film.
1.

23 is a wrinkle presser that hangs down on punch 11, and then presses punch 1.
The punch 11 is arranged so as to slightly protrude from the lower end surface 12 of the punch 11 and surround the outer circumferential surface 24 of the punch 11, and has a dust suction space 26 in a lower inner surface 25 for vacuum removing chips 19 of the thin film 10 generated during cutting.

28 is disposed below the die 17 and facing the punch 11 in order to stack the thin films 30 cut in the take-out container.

Reference numeral 32 denotes a thin film feeding section, and drive rollers 3 are paired across both ends 33 of the thin film 10 to feed the thin film 10.
4, a pinch roller 35, and a rotational drive source 36 connected to the drive roller 34.

38 is a vacuum source that connects the vacuum suction hole 13 of the punch 11 and the die 1.
7. The suction space 21 is connected to the dust suction space 26 of the wrinkle presser 23.

39 is a compressed air source connected to the intake space 21 of the die i7.

A mechanism control section 40 is connected to the drive source 15 and the rotary drive source 36.

A central control section 41 is connected to a vacuum source 38, a compressed air source 39, and a mechanism control section 40, respectively, in order to control the overall operation.

Next, the operation of the embodiment of the present invention configured as above will be explained.

As shown in FIGS. 1 and 2a, the compressed air source 39 is activated by a command from the central control unit 41, and the compressed air 20 is spouted from the intake space 21 of the die 17, thereby causing the thin film 1 to 1.
01 When the thin film 10 is positioned between the punch 11 and the die 17 with the buoyancy applied to it and the sagging due to its own weight removed, the mechanism control section 40 is activated based on a command from the central control section 41. Through this, the drive source 15 is activated and the punch 11 begins to descend. At this time, the wrinkle presser 23 hanging from the punch 11 descends together with the punch 11, as shown in Fig. 2b.
As shown in the figure, the wrinkle presser 23 touches the thin film 10 in advance of the lower end surface 12 of the punch 11 to remove the wrinkles on the thin film 10 and maintain this state. The wrinkle presser 23 stops at this point, but the punch 11 continues to descend further and cuts the thin film 10 as shown in FIG. 2c. At the same time as the punch 11 begins to cut the thin film 10, the compressed air source 39 stops operating and the vacuum source 38 starts operating in response to a command from the central control unit 41. When the vacuum source 38 is activated, the vacuum suction hole 13 of the punch 11 vacuum suctions the cut thin film 30, and
Chips 19 generated when cutting the thin film 10 are removed from the air suction space 21 and the dust suction space 26 by vacuum suction. The thin film 30' vacuum-adsorbed on the lower end surface 12 of the punch 11 or the second
As shown in FIG. d, the operation of the vacuum source 38 is stopped at the same time as the punch 11 is transferred to the take-out container 28, so that the punch 11 is separated from the lower end surface 12 of the punch 11 and stored in the take-out container 28. When the cut thin film 30 is stored in the take-out container 28, the drive source 15 is activated by a command from the mechanism control unit 40, and the punch 11 and the wrinkle presser 23 hanging from the punch 11 are moved as shown in FIG. 2e. rise again. Punch 11 and wrinkle presser 23
When it completes its rise, the compressed air source 39 operates and blows out the compressed air 20 from the intake space 21. At the same time, the mechanism control unit 4
In response to the command 0, the rotational drive source 36 is activated, and the drive roller 34 and pinch roller 35 feed the thin film 101 by a predetermined distance, thereby completing the first cutting operation. Subsequently, the second and subsequent cutting operations are repeated in the same manner as the first cutting operation. In this way, the cutting operation continues, but since the required number of cut thin films 30 to be stacked in the take-out container 28 is known in advance, this value is transferred to the central control unit 4.
By setting this value to 1, when the accumulated value matches the value set in the central control unit 41, the device automatically stops and the cutting operation ends. As explained above, according to the present invention, chips generated when cutting a thin film are removed by a vacuum method from both the punch side and the die side, and the thin film is fed without contacting the necessary parts of the thin film. Because of this, there is no chance of chips getting mixed in between the stacked thin films, resulting in a clean, high-quality product.

In addition, when cutting the thin film, the thin film is cut with a jet of compressed air and a wrinkle press without any manipulation of the thin film, and the cut thin film is transferred by vacuum suction, so that it can be sized without any misalignment. It is possible to obtain products with high precision and uniform quality. Furthermore, when feeding the thin film, compressed air is ejected from below, which allows for good feeding without the cut surface of the thin film getting caught in the corners of the die, and because cutting is done continuously, production is extremely efficient. It is efficient and can easily reduce the cost of the product. Therefore, the apparatus of the present invention is easy to operate and can produce high-quality products with high precision efficiently and at low cost, so its effects are significant.
