VORRICHTUNG UND VERFAHREN ZUM ZUBRINGEN VON ERZEUGNISSEN VON AUSGEWÄHLTEN STAPELN VON ERZEUGNISSEN
摘要
A number of product feeders comprise a conveyor underlying a friction wheel operated by a pulsed drive. A continuously rotating drive shaft is coupled to a selected feeder by a controller coupling a drive wheel on the drive shaft with a drive transmission wheel associated with the conveyor of the feeder. This may be effected by an air cylinder of the feeder operating under control of the controller to move the drive transmission wheel into a position whereat it is driven by the drive wheel. Alternatively, the drive wheel may be clutched under control of the controller. The pulsed friction wheel rotates through an arc in order to drop a product from a stack of products partially supported by the friction wheel onto the now moving conveyor. A downstream product sensor, when sensing that a product has been delivered, signals the controller so that the controller decouples the conveyor from the drive shaft.
