Abstract

In multilayer ceramic manufacturing operations green sheets are placed in trays prior to their being bonded in an automatic stacker. This apparatus uses an optical system to count the sheets to insure that the proper number are in place prior to the trays being placed on the automatic stacker. This would reduce production time lost when a tray contains less than the specified amount. Prior to stacking for lamination, green sheets are placed in a tray with spacer papers between them. The sheets are either 8 mils or 11 mils thick, and the spacer papers are 3 mils in thickness. Each tray is to contain a specific number of identical green sheets which represent one layer in the finished multilayer ceramic.
