<p>PURPOSE:To perform an automatic conveyance of parts, by storing a conveyance control quantity per tracking zone unit of a conveyance line, and providing an output for the starting of a conveyor according to the conveyance control quantity corresponding to the quantity required at the point of time when the conveyance of the parts is detected. CONSTITUTION:A conveyance control quantity 8 is stored in each tracking zone 7, an output signal for the starting of a conveyor pertaining to the corresponding tracking zone is outputted according to the conveyance control quantity 8 corresponding to the point of time when an input signal is detected, and this method allows the automatic conveyance of parts in the corresponding tracking zone. In which case, when a conveyance detecting signal from a zone No e to a zone No d is inputted, in case the type of a part in the foremost tracking table of the zone No e is ''1'', the conveyance control quantity is e<l>i...e<m>i. Then, the tracking table for the corresponding part is eliminated from tracking tables in the zone No e, the number e<1> of parts is reduced, and the number e<l>i of parts in a zone No e<2>i is added to form a tracking table for the corresponding part toward a zone No e<2>i.</p> |
