Material blending/supplying device and method

Abstract

Disclosed is a material blending / supplying device (1) that weighs the respective particulate materials supplied by a plurality of material suppliers (10A, 10B, 10C, 10D) by means of a weighing mechanism (20) so that the materials have a predetermined mass ratio, and then blends the materials with a blending means (30) and supplies the blended materials to a molding mechanism (9). The material blending / supplying device is provided with: a processing capacity detection means (61) for detecting the processing capacity of the molding mechanism in terms of the material processed per unit of time; a blend supply capacity detection means (61) for detecting the blend supply capacity in terms of the amount of blended material that can be supplied to the molding mechanism per unit of time; and a blend supply capacity control means (61), for comparing the processing capacity and the blend supply capacity based on a predetermined programme, and updating the blending / supplying process so as to reduce the blend supply capacity when the blend supply capacity exceeds the processing capacity and the blend supply capacity can be reduced to a predetermined level.

Description

technical field [0001] The present invention relates to a material mixing and supplying device and a material mixing and supplying method for mixing a plurality of powder and granular materials in a predetermined ratio and then supplying them to a molding machine. Background technique [0002] Conventionally, as a material mixing and supplying device that mixes a plurality of powder and granular materials in a predetermined ratio and supplies the mixed material to a molding machine, there is known a material mixing and supplying device that is equipped with A single-batch type weighing machine with sensors such as a load cell measures each powder material supplied from a plurality of material feeders that store various powder materials separately, so that the powder material is Specified mass ratio. One batch of material weighed by the weighing machine is mixed by a mixing mechanism such as a mixing drum (container for mixing) downstream of the weighing machine, and then su...

AI Technical Summary

Problems solved by technology

[0009] Among them, when the material is replaced, the mass ratio of each material is changed, the molded product is changed (die change), the manufacturing lot number (lot) is changed, or the molding is completed (the operation is completed), etc., wait and hold in each part after the weighing machine Since the materials used are mixed with various materials, there is a problem that it is difficult to recycle and the amount of waste increases.
