Device for counting and packing elements of uniform shape, in particular circular lids for drinks cans

摘要

The invention relates to a device for counting elements of uniform shape, in particular circular lids for drinks cans. The invention is based on the object of ensuring that the most precise possible counting and packing of a specifiable number of covers at a high frequency, for example 400 lids per second. This object is achieved according to the invention essentially by means of the following features: a) the gearwheel (5) is provided with an outer contour (5') which is exactly matched in a positively engaging manner to the edge shape (2') of the elements (2) arranged immediately behind one another, b) the centring device (3) consists of a centring tube (25), c) the elements (2) are led past the outer contour (5'), which protrudes into the centring tube (25), of the gearwheel (5) with their edge shape (2') in a positively engaging manner, d) the gearwheel (5) synchronously drives a pulse generator wheel (6) which dips into a forked photoelectric barrier (7), e) the pulses emitted by the pulse generator wheel (6) are fed to an electronic counting device (9). <IMAGE>
