Abstract
A product feeding device for use in a combination weigher which includes a plurality of conveyor troughs arranged radially for feeding product to corresponding weighing units and a central product feeder for distributively feeding product to the respective conveyer troughs. The device comprises a product detecting device which revolves around the central feeder for sequentially detecting the amount of product carried by each conveyer trough in order to control the amount of product fed to each conveyer trough.
Claims13
A product feeding device used in a combination weigher comprising a plurality of weight units arranged circularly around a central axis, a plurality of conveyer troughs radially arranged around said central axis for feeding product to said weigh units, and a central product dispensing means for feeding product to said conveyer troughs, said device comprising:
- a detector;
- means for revolving said detector about said central axis such that said detector sequentially detects the amount of product on each of said conveyer troughs, said detector being adapted to provide a detection signal corresponding to the amount of product detected in each conveyer trough, and control means responsive to said detection signal for controlling the amount of product fed from said product dispensing means to the corresponding conveyer trough.
A product feeding device used in a combination weigher comprising a plurality of weight units arranged circularly around a central axis, and a plurality of conveyer troughs arranged around said central axis for feeding product to said weigh units,
- said device comprising a body including an upper inlet port, a side outlet port adapted to face the proximal ends of said conveyer troughs one at a time, and a sliding surface sloping primarily in one direction connecting said inlet and outlet ports for feeding product to the conveyer troughs one at a time, and means for rotating said body about said central axis whereby product fed into said inlet port is adapted to slide down said sloped surface and out said outlet port for sequential delivery to the conveyor troughs.
