ABSTRACT:
In an apparatus and method for discharging weighed articles in a combinatorial weighing system, weighed articles discharged from a plurality of weighing hoppers are selectively released into first and second collecting routes of a collecting chute. The outlet of each collecting route is provided with a timing hopper having a gate. The gates of the two timing hoppers are opened and closed by respective drive units. The arrangement is such that one of the gates can be opened while the other gate is in the closed state or by the time the other gate is completely closed. Control is effected in such a manner that when weighed articles are released into one of the collecting routes from the weighing hoppers, the timing hopper corresponding to this collecting route is opened to completely discharge weighed articles previously released into the timing hopper. The discharge of previously released weighed articles is accomplished during the time needed for the weighed articles just released to reach the timing hopper.
