Abstract
A material processing system with a pallet changing system includes a first base frame, a first pallet positionable on the first base frame, and a second base frame in alignment with the first base frame. The second base frame has two running rails on which the first pallet is displaceable longitudinally toward or away from the first base frame via rollers. A guide contour is arranged on one of the running rails for laterally guiding at least one roller, and/or at least one lateral guide element is fixed relative to the second base frame or the first pallet arranged in the second base frame and projects beyond one of the running rails so that, when a lateral force is applied onto the first pallet arranged on the second base frame, lateral movement of the first pallet relative to the second base frame is limited by a one-sided stop.
