Verfahren zum Herstellen geschäumter Gegenstände und Füllvorrichtung für geschäumte Teilchen aus thermoplastischem Kunststoff zur Verwendung bei solchem Verfahren

摘要

Disclosed herein is a method of producing an expansion-molded article by filling foamed particles of a thermoplastic resin into a mold and then causing the foamed particles to expand and fusion-bond under heat. The method comprises measuring the weight of the foamed particles to be filled to fill a fixed weight of the foamed particles into the mold, thereby expansion-molding them. A filling apparatus of foamed particles of a thermoplastic resin is also disclosed. The apparatus comprises a weigh hopper equipped with a weighing means; a foamed particle feeder adapted to control the amount of the foamed particles of the thermoplastic resin to be fed to the weigh hopper according to the weight of the foamed particles contained in the weigh hopper; a particle feed hopper adapted to temporarily keep a fixed weight of the foamed particles, which have been weighed in the weigh hopper, and then to transfer them; and a filling machine for filling the foamed particles into a mold.
