<p>This invention concerns an apparatus adapted to control both the laying and transportation, on conveyor belts, of indexed workpieces, manufactured by a line comprising a plurality of automatic machines. The subject apparatus substantially includes a plurality of continuously operating conveyor belts, arranged sequentially to each other, among which there are provided temporary workpiece stop means. Each automatic machine is connected to the next by means of a continuously operated conveyor belt and one of the temporary stop means. Control is actuated by picking up, from the following machine, one of the manufacturing cycle characterizing signals thereof, which is sent to a pair of timers, wherein the first determines the temporary stop means enable delay time, while the second determines the enable time duration. Said signal is sent by the following machine to the timers and by controlling the latter, it is possible to prevent that on the conveyor belt associated with said machine there arrives any workpiece manufactured by the preceding machine while the just manufactured workpieces are laid on the belt.</p> |
