Abstract
The invention relates to a transfer device for goods delivered on a first conveyor device, particularly cans, which are transferred in groups, as a row in the direction of conveyance of said first conveyor device, from said first conveyor device to a second conveyor device, the depositing of the goods onto the second conveyor device taking place in the manner that said row extends transverse to its direction of conveyance, having a receiving device which holds the corresponding group of goods upon the transfer and is guided by at least one drive along a path of movement, the receiving device being a suction beam which is connected by a switch device to a source of vacuum, the switch member of which switch device is brought into a vacuum connect position or vacuum disconnect position as a function of the position of the suction beam. It is provided that the switch member (27) is driven by an electric actuator (servomotor M2) which is connected to an electric open-loop control device (22) or electric closed-loop controller which has at least one sensor (S1, S2) which detects the instantaneous position of the suction beam (17).
