Abstract
The invention relates to an apparatus for handling sheets or the like. The apparatus comprises a bridge structure displacable on rails, an upper carriage displaceable on the bridge structure in a direction perpendicular to the rails, vertical beams attached to the upper carriage, and a carriage displaceable on the vertical beams in the direction thereof. The carriage is provided with lifting forks for removing a sheet pack or the like from a shelf place. The carriage is further provided with a gripper frame for picking up a sheet or the like from the shelf place or the like. In order to provide a simple and reliable apparatus, the carriage is provided with arms pivotable around a horizontal axis from a first position above the lifting forks and essentially in parallel therewith to a second position, and vice versa. The gripper frame is, at its symmetry axis essentialy parallel to the carriage, fastened between the arms in such a manner that the gripper frame is entirely beyond the edges of the carriage in the first and the second position of the arms. The gripper frame is pivotable around an axis going through the connection points between the arms and the gripper frarme.
