ABSTRACT:
A combinatorial weighing system includes a combinatorial weighing apparatus, a packing machine and master/slave changeover switch. The combinatorial weighing apparatus has a plurality of weighing machines for sensing the weight of articles supplied thereto, and a calculation control unit for performing a combinatorial calculation, based on weight data from the weighing machines, to obtain an optimum combination, and for causing weighing machines corresponding to the optimum combination to discharge their articles. The articles are then packed by the packing machine. The master/slave changeover switch switches between a mode in which the packing machine is the master of the weighing and packing operation and a mode in which the weighing apparatus is the master of the weighing and packing operation. The arrangement results in a combinatorial weighing apparatus which has greatly simplified hardware and which can operate in association with either a master- or slave-type packing machine.
