Device for automatically filling and packing predetermined weight of product in containers.

摘要

A kind of automatic rotary weighing and packing machine having a plurality of weighers (1-8) radially or annularly arranged on a circular rotary table (10) for automatically effecting such processes as filling of product, weighing and judgement at respective positions around the table, which is especially suitable in the case where the product to be packed is sticky granular or powdered bulk material and the packing container is a bag or the like. This machine uses no weigh hopper or backet in which sticky product is liable to remain to cause weight error and the packing container is held by a holding mechanism (12) attached to each weigher (1-8) and directly filled with product, which is then weighed and sealed. A fixed amount feeding device (24) is used for feeding product in the container (16) and it is throughout controlled, based upon the result of weighment for keeping the weight of product packed in each container always at a predetermined value.
