Device and method for independently transporting two glass panes in a pane processing device

A transport device configured for transporting upstanding glass panes, comprising:

• a pane processing device with a processing unit which can be moved up and down along a supporting plane formed by a supporting wall;
• a first horizontal conveyor arranged in a lower region of the supporting wall and forms an upward-facing first conveying surface, which is linearly movable along a horizontal conveying direction for transporting a glass pane standing on the first conveying surface;
• a second horizontal conveyor arranged in line with the first horizontal conveyor and forms an upward-facing second conveying surface, which can be moved linearly along the conveying direction;
• a suction conveyor comprising a perforated suction belt;
• wherein a section of the suction belt runs over a suction chamber configured to be able to suck a glass pane onto the suction belt;
• wherein said section of the suction belt extends in the supporting plane parallel to the conveying direction from an area above the first conveying surface to an area above the second conveying surface;
• wherein the transport device is configured to move the second conveying surface synchronously with the first conveying surface or independently of the first conveying surface;
• and
• wherein a spacer movable relative to the supporting wall is arranged in the region above the second conveying surface, which spacer can be moved into a working position in which a guiding surface of the spacer is located on the side of the suction belt opposite the suction chamber.
