Stacker module for a converting machine

A stacker module for a folder-gluer machine, the stacker module being located downstream of a transfer module in a direction of transportation of the folder-gluer machine and configured to receive folding boxes from the transfer module, wherein the stacker module comprises:

• a loading surface configured to receive a plurality of folding boxes and to descend vertically as a number of folding boxes on the loading surface increases,
• a linearly movable ejector configured to be moved from a retracted position to an extended position and eject a stack of folding boxes from the loading surface, and
• an upper guide configured to move between a clearing position which is vertically distant from an upper surface of the stack, and a guiding position, in which the upper guide is located closer to the upper surface of the stack,
• wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the extended position,
• wherein the upper guide comprises a first elongated guide member and a second elongated guide member,
• wherein the first elongated guide member and the second elongated guide member extend in the direction of transportation,
• wherein the ejector comprises a first pusher and a second pusher arranged laterally of each other,
• wherein each pusher is linearly displaceable in the direction of transportation and configured to move in unison between the retracted position and the extended position, and
• wherein the first pusher and the second pusher are laterally and longitudinally displaceable in relation to each other, such that their retracted position and extended position in the direction of transportation are different.

• wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the extended position, and
• a front abutment guide configured to move between an abutment position in which the front abutment guide is positioned in front of a front leading edge of the folding boxes as they are deposited onto the loading surface, and a clearing position in which the front abutment guide is positioned distant from the stack such that the ejector can evacuate the stack from the loading surface, wherein the front abutment guide is moved vertically upward when the loading surface is descending.
