Weighing bridge for conveyor weighing arrangements - has wt. support rollers frame tilting w.r.t. conveyor about central axis

摘要

The weighing bridge is for conveyor belt weighing arrangements of the electromechanical or electronic type and has rollers mounted on a carrier or a frame bearing the wt. of the goods with electromechanical transducers in the path of the spring or force travel. It is improved w.r.t. conventional bridges to achieve higher accuracy with simpler construction and adjustment. The roller carrier or frame (11) swivels about an axis (9) lying in the conveyor feed direction and approximately symmetrical to the conveyor belt (12). The bearing stud (9) is held in position by a clamp (8). The carrier forms part of a bridge (1) consisting of a wt. supporting rod (2) and a plate spring (3) which counteracts the tendency of the bridge to distort. The vertical movements of the ends of the carrier are limited by straps (14).
