Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a green sheet cutting device that can be used for mass producing multilayer ceramic capacitors.

BACKGROUND OF THE INVENTION In recent years, the green sheets used in multilayer ceramic capacitors have become thinner, and as a result, it has become increasingly difficult for green sheet cutting devices to transport the green sheets, and transport technology has become more important.

A conventional green sheet cutting device will be described below with reference to the drawings. FIG. 6 shows a configuration diagram of a conventional green sheet cutting device.

In Fig. 6, 1 is a green sheet, 1b is a cut green sheet, 6 is a cutting blade, an aid backing plate, 9 is a carrier tape, 1o is a winding motor, 12 is a peeling edge, 13 is a sensor, and 1 is a cutting blade. The green sheet cut into a predetermined size by the blade 6 is transferred and taken out by using the angle of inclination of the tray 14, which is mounted obliquely.

In the three-page green sheet cutting device configured as described above, the winding motor 10 is continuously rotating, and by winding up the carrier tape 9, the green sheet 1a is separated from the carrier tape 9 by the peeling edge 12. It is sent forward while being peeled off. Next, the green sheet 1a is transferred while rubbing against the cut green sheet 1b on the tray 14, and is stored in the tray 11T114. The green sheet 11L transported in this manner is cut by reading the length of the green sheet 1a with the sensor 13, and without stopping the take-up motor 10, the green sheet is cut by the cutting blade 6 as the backing plate 8 rises as it is fed out. are doing.

Problems to be Solved by the Invention However, with the above configuration, the green sheet is extremely thin and soft, so the transported green sheet 1a could hardly be transported due to friction with the cut green sheet 1b. .

Further, since the winding motor 10 continuously rotates, the fed green sheet was jammed between the cutting blade 6 and the backing plate 8 after being cut by the cutting blade 6. As a result, when transporting the green sheets, the green sheets are actually taken out one by one manually, which poses the problem of greatly hindering productivity.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a green sheet cutting device that can automatically transfer green sheets without relying on human hands.

Means for Solving the Problems In order to solve the above problems, the green sheet cutting device of the present invention guides the green sheet to a predetermined position with a vane, and then cuts the green sheet with air from an air blowing pipe. It has a function of pressing the green sheet against the suction plate, suctioning the green sheet with the suction plate, and then transporting the green sheet while slightly sliding it between the green sheet and the suction plate. At the same time, it also has a function that temporarily stops the take-up motor when cutting the green sheet, stopping feeding of the green sheet before cutting.

6. Beno action In the present invention, with the above-described configuration, the green sheet is transported by the suction plate, so that it can be reliably and mechanically taken out. Furthermore, since the take-up motor is stopped when cutting the green sheet and the green sheet is cut after stopping feeding, the green sheet does not become jammed.

EXAMPLE Hereinafter, a green sheet cutting device according to an example of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration diagram of a green sheet cutting device according to an embodiment of the present invention. In Figure 1, 1a is a green sheet, 1b
is a cut green sheet, 2 is a suction plate, 3 is a wing plate, 4 is an air blowing pipe, 5 is a cylinder, 6 is a cutting blade, 7 is an absorber, 8 is a backing plate, 9 is a carrier tape,
10 is a winding motor, 12 is a peeling edge, 13 is a sensor, and 14 is a receiver. The operation of the green sheet cutting device configured as described above will be described below with reference to FIGS. 1 to 6.

Page 6 First, in FIG. 1, when the carrier tape 9 is wound up by the winding motor 10, the green sea 1a is peeled off from the carrier tape 9 at the peeling edge 12, and the blade plate on the air blowing pipe 4 is removed. You will be guided to 3. At this position, as shown in FIG. 2, the green sheet 1a is pressed against the suction plate 2 by air from the air blowing pipe 4, and at the same time, the green sheet 1a is vacuum suctioned from the suction plate 2 by the suction device 7. The vacuum-adsorbed Green Sea) 1a is then transferred by a cylinder 6 as shown in FIG. At this time, the drawing speed of the cylinder 6 is set higher than the winding speed of the carrier tape 9, and the green sheet 1a is forcibly transferred while causing slippage between the green sheet 1a and the suction plate 2 due to the speed difference.

Next, as shown in FIG. 4, when the length of the green sheet 1a reaches a predetermined length, the sensor 13 detects that the length is the same, and the backing plate 8 rises, and the green sheet 1a is cut off by the cutting blade. 6 and 7 base 7 are cut to a fixed length. At this time, in order to prevent the green sheet from clogging, the take-up motor 10 is temporarily stopped and the feeding of the green sheet is stopped before cutting.

Finally, when the suction plate 7 retreats to a predetermined position as shown in FIG. Green Sea) 1b
Stack and store.

As described above, according to this embodiment, a vane plate for guiding the green sheet is provided, the green sheet 1a is sprayed onto the suction plate 2 by the air blowing pipe 4, and the green sheet 1a is suctioned by the suction device 7. and the suction plate 2, forcibly transferring it while causing a slight slippage between the suction plate 2 and the
On the other hand, when cutting the green sheet, the winding motor 10
By stopping the feeding of the green sheet and cutting the green sheet, the green sheet can be transported reliably and automatically.

Effects of the Invention As described above, the present invention provides green sheet guide vanes,
An air blowing pipe, a suction plate for green sheet transfer, and a suction device are installed to forcibly transfer the green sheet, and by stopping the feeding of the green sheet and cutting it when cutting the green sheet, the transfer and removal of the green sheet is ensured. and can be done automatically rather than manually.
