Abstract
An apparatus for controlling the operation of a packaging machine of the type which carries out the operations of causing a tube film placed around articles under transport to be cut and sealed between adjacent articles for being successively formed into bags, then causing individual bags, each with an article contained therein, to be conveyed forward by a delivery conveyor, causing the bags to be sequentially transferred from the delivery conveyor onto moving surface plates, causing each surface plate to be covered with a cover member, and then causing the interior of the cover member to be placed under a vacuum atmosphere while the open end of the bag is hermetically sealed. A bag sensor sequentially detects the passage of open ends of bags on the delivery conveyor, and a surface plate detecting sensor sequentially detects the passage of individual surface plates. Information received from the bag sensor and information received from the surface plate detecting sensor are checked against each other for finding relative positional deviation between the bag and the surface plate. Any positional deviation is corrected according to the result of such checking.
