Abstract
In a method and apparatus for manufacturing ceramic green sheets, first and second long ceramic green sheets are selectively drawn out by means of first and second draw-out rollers into a commonly used punching station. In the punching station, predetermined areas of the long ceramic green sheets are punched, so that ceramic green sheet cut pieces having predetermined sizes are formed. A cut piece held by a punching head is conveyed to a lamination station adjacent to the punching station, where lamination and press-bonding are carried out.
Claims20
A lamination apparatus for a ceramic green sheet comprising:
- one punching station disposed in a fixed position and adapted to punch a predetermined area of each of a plurality of long ceramic green sheets so as to form a ceramic green sheet cut piece having a predetermined size, and one lamination station disposed in a fixed position adjacent to the punching station and adapted to laminate the ceramic green sheet cut piece, such that a plurality of different types of long ceramic green sheets are processed;
- a single punching head which cuts each of the plurality of long ceramic green sheets in the punching station so as to form a cutting line enclosing the predetermined area thereof, and which conveys the piece from the punching station to the lamination station while holding the formed ceramic green sheet cut piece;
- a feeding mechanism for feeding each of the plurality of long ceramic green sheets in a longitudinal direction of the long ceramic green sheets, respectively;
- and
- a plurality of introducing mechanisms for selectively introducing respective ones of the plurality of long ceramic green sheets from different directions into the punching station disposed at the fixed position.
A method of laminating a ceramic green sheet comprising the steps of:
- selectively introducing each of a plurality of different kinds of long ceramic green sheets from different directions into one punching station that is disposed at a fixed position and having a single punching head;
- punching a predetermined area of each of the plurality of long ceramic green sheets to form a ceramic green sheet cut piece having a predetermined size on the punching station;
- conveying the ceramic green sheet cut piece from the punching station to a lamination station;
- and
- laminating the ceramic green sheet cut piece in the lamination station.
