WEIGHT PROPORTIONER Russian patent published in 1995 - IPC

FIELD: weight measurement technology. SUBSTANCE: resting on weight receiving platform is section of belt conveyer which is chute-shaped in form. Weight receiving platform is connected via hinged with suspensions coupled with force sensor which is connected to control unit. Hinges are located in horizontal plane above calibrating roll at distance not exceeding half the distance between calibrating roll and packing roll. Calibrating element made in form of part of hollow cylinder is mounted coaxially relative to packing roll. Its working edge is located above lower surface of packing roll at distance equal to 0.04-0.25 of its diameter. Mounted in the bin are high and low level sensors electrically connected with drive of belt conveyer. Distributing funnel is provided with cam and is linked with turn drive. Additional limit switches are mounted for alternate engagement with cam and are linked with control unit connected to the drive of distributing funnel. EFFECT: enhanced efficiency. 2 cl, 5 dwg
