Abstract

A combinatorial weighing apparatus comprises weighing receptacles (5), a distributing device (1) for distributing products to be supplied, a feeding device (2) for feeding the products from the distributing device (1) to a respective one of the weighing receptacles (5), a driving device (3) for oscillating the feeding device (2) and a coupling device (4) for detachably coupling the feeding device (2) to the driving device (3) with a first coupling piece (12) and a second coupling piece (8), a slide (23) which is displaceably connected to the first coupling piece (12), one of the coupling pieces (8, 12) being connected with the feeding device (2) and the other coupling piece (12, 8) being connected to the driving device (3), a tension member (33) connected to the slide (23) for displacing the slide (23) along a displacement direction from a first position into a second position in which the slide (23) can be locked against displacement into the first position, a support bolt (19) having a shaft (20) and a head (21) connected to the shaft (20), an elongate hole (28) extending substantially parallel to the displacement direction and having a first portion (29) which is greater than the head (21) and a subsequent second portion (30, 31) which is smaller than the head (21), the slide (23) and the second coupling piece (8) forming two coupling members, the shaft (20) being connected to one of the coupling members and the elongate hole (28) being connected to the other one of the coupling members. The combinatorial weighing apparatus guarantees a reliable, detachable and playfree coupling of feeding device and driving device.
