DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laminating and cutting ceramic green sheets in which a plurality of ceramic green sheets are laminated and then cut to obtain a plurality of ceramic green sheet laminates.

[0002]

2. Description of the Related Art When a ceramic green sheet is laminated by pressing with a laminating press, a pressing force is applied while a plurality of ceramic green sheets are stacked on a jig. Conventionally, a plurality of ceramic green sheets in a laminated state are removed from the jig after the laminating press by the laminating press and supplied to the cutting machine because the jig is in the way.

[0003]

When a ceramic green sheet is laminated and pressed by a laminating press, it is necessary to heat the ceramic green sheet to about 80 to 90 ° C. When it is necessary to remove the jig after the laminating press, the temperature of the ceramic green sheet falls during that time. In order to set the same temperature conditions at the time of cutting in the cutting machine, the ceramic green sheet once dropped Needs to be raised again, which not only takes time for the temperature rise, but also increases the energy consumption for the temperature rise. Moreover, it is difficult to compact the laminating press and cutting machine because of the necessity of a step of removing the jig. Furthermore, the cutting accuracy is low because the laminated ceramic green sheets are in a free state when cutting with the cutting machine. Is difficult to improve.

The present invention has been made in view of the above circumstances, and has been made in order to reduce the amount of energy consumption, make the laminating press and cutting machine compact, and improve the cutting accuracy.・
It is intended to provide a cutting method.

[0005]

In order to achieve the above-mentioned object, the present invention provides a method for producing a plurality of ceramic green sheet laminates by laminating a plurality of ceramic green sheets after laminating the plurality of ceramic green sheets. After the green sheet is positioned and mounted on the mounting plate via the sheet made of synthetic resin, the pressing force of the laminating press is applied to the plurality of ceramic green sheets, and then the stacking state is performed on the mounting plate. Ceramics in
Green sheet from stacking press to cutting machine
The ceramic green sheets are immediately conveyed while being placed on the mounting plate, and the ceramic green sheets stacked on the mounting plate are cut by a cutting machine so that the cutter is cut into the lowermost sheet. It is characterized in that a sheet laminate is obtained.
