ABSTRACT:
Conveyor system particularly suitable for the bulk transfer of cigarettes from one or more manufacturing machines to one or more packaging machines, and comprising at least one device for controlling the quantity of cigarettes at a determined position.
The control device comprises a plurality of photoemitter elements disposed at different levels relative to the controlled position, which direct their rays through the controlled position to corresponding photosensitive elements. An electrical circuit controls drive means for the conveyor system by means of a voltage which in terms of absolute value and sign is a function of the number of photosensitive elements illuminated by the corresponding photoemitter elements.
