ABSTRACT:
A compact combinational weighing apparatus comprises a compact housing structure for weighing devices and a remote control unit which are connected only by an elongate signal-transmitting cable. Inside the housing are a number of article batch handling units disposed in a linear array. Each article batch handling unit includes a pool hopper of a double-gate structure for receiving an article batch from an article feeder and two weigh hoppers for weighing received article batches. The article batch in the pool hopper is selectably discharged into either of the weigh hoppers below by opening the gate corresponding to the selected weigh hopper. The two gates of each pool hopper are closed by a single spring and opened by individual rotary solenoids. Load cells for weighing the article batches in the pair of weigh hoppers belonging to each article batch handling unit are disposed in mutually lined-symmetrical relationship with respect to a horizontal line. Rotary solenoids for opening the weigh hopper gates are disposed in efficiently space-saving manners. A funnel-shaped article discharging unit into which article batches are discharged from weigh hoppers has buffer plates strategically placed to uniformize the time it takes for article batches from the various weigh hoppers to reach an outlet at its bottom.
