Infeed station and stack gripper of a palletizing system and method for transferring stacks from an infeed station to a stack gripper

A method for transferring stacks from an infeed station to a stack gripper including a carriage supported on a machine frame of the infeed station so as to be movable laterally,

• a stack conveyor mounted on the carriage for conveying stacks from an infeed position to a transfer position, from where the stacks can each be removed by the stack gripper,
• at least two stack chambers which are arranged on the carriage and in which the stacks can be centered;
• and a control unit, wherein a stop element supported on the carriage is assigned to each stack chamber and is movable between a working position and a retracted position, wherein in the working position, the stop elements project into the associated stack chamber in such a way that the stacks can be moved by the stack gripper from a forward holding position of the transfer position towards the stop elements and placed against the stop elements, the method comprising moving the stacks or a single stack by the stack conveyor into a forward holding position where the stop elements are then moved out of the retracted position and into the working position by a certain distance from the rear end of the corresponding stack, and pushing the stacks or stack by the stack gripper towards the stop element or elements until the stacks or stack rests against the stop element or elements.
