Raw material consumption measurement method, raw material supply method and raw material supply device

摘要

PPROBLEM TO BE SOLVED: To provide a method for measuring a raw material consumption, a raw material feeding method, and a raw material feeder, which enable the simplification of a constitution and a reduction in cost, and which enable a plurality of raw materials to be constantly mixed together at a fixed rate. PSOLUTION: The per-unit-of-time reference extrusion output of the raw materials 14a and 14b for use in a molder 12 is set, and the raw materials 14a and 14b of an amount equivalent to the reference extrusion output are continuously fed to a feed hopper 32. The per-unit-of-time variation of the weight of the raw materials 14a and 14b for the feed hopper 32 is measured, and undergone substraction or addition with respect to the reference extrusion output, so that an actual extrusion output can be computed. In addition, the raw materials 14a and 14b are supplied to the feed hopper 32 so that the variation of the weight can be eliminated. PCOPYRIGHT: (C)2004,JPO
