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

摘要

An infeed station has a carriage that is supported on a machine frame of the infeed station in a way that allows it to be moved laterally and a stack conveyor mounted on the carriage for conveying stacks from an infeed position to a transfer position, from which the stacks can each be removed by the stack gripper. The stacks can be centered in two stack chambers, which are arranged side by side on the carriage. A stop element supported on the carriage is assigned to each stack chamber and can be moved between a working position and a retracted position, such that in their 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 stacks positioned on the stop elements are gripped by the stack gripper between a finger and pressing means and conveyed to a pallet.

主权项

1. An infeed station and stack gripper of a palletizing system, comprising 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, the stack conveyor having gaps, at least two stack chambers which are arranged on the carriage and in which the stacks can be centered; and a control unit, wherein the stack gripper has stop edges, pressing means and fingers that cooperate to grip a stack, 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 step edges of the stack gripper from a forward holding position of the transfer position towards the stop elements so that a rear end of the stack is placed against the stop elements, wherein the stack gripper is positionable and moveable so that the fingers enter the gaps of the stack conveyor, and wherein the stop elements are movable horizontally in or opposite a direction of conveyance of the stacks only to adjust to a format of the stacks but not for moving the stacks.
