Abstract
A self-cleaning weighing hopper to be used in a weighing apparatus is particularly adaptable for utilization with a sticky product. The hopper has two rotary doors containing a series of tined panels. One tined panel on each of the two doors extend toward each other so as to form a hopper bottom to hold a product charge. The panels on the two doors rotate in unison to release the weighed product charge into a receptacle. The hopper includes a comb scraper through which each tined panel rotates following release of the product charge. The comb scraper removes the sticky remnants of the product charge from the tines of the panels while the weighing apparatus is in operation. The doors are operated by a sliding arm in response to an actuator. A pin on the arm is guided by a spring/linkage mechanism along a slot on a guide plate and a stop is provided on the arm to insure proper actuation.
