Abstract
A device for feeding a packaging machine via a bag stack feeder possesses at least one holder to secure a stack of bags. To date an operator placed the corresponding empty bags in stacks on a chain conveyor which fed the bags into the packaging machine. Due to the short cycle time, the manual loading tied an operator continuously to the machine. In order to avoid this, a bag stack feeder is equipped with a plurality of tray-like carriers, each fitted with a holder and each being detachable from the bag stack feeder. These carriers are respectively stored in large numbers in a magazine, which is exchangeable as a unit.
