Transport mechanism and method for transporting a print medium in a printing system

摘要

A transport mechanism and method are provided for transporting sheets of a print medium in a printing system. The transport mechanism includes a first conveyor device having a first conveyor body configured to hold a plurality of sheets of print medium and to convey the sheets along the transport path, and a transfer system including a second conveyor device having a second conveyor body configured to hold the sheets and to convey the sheets further along the transport path. The transfer system is configured to transfer the sheets from the first conveyor body to the second conveyor body in a transfer region. The second conveyor body is adjacent the first conveyor body in the transfer region, and the transfer system includes a suction device configured to provide an under-pressure at the second conveyor body for contactless transfer of the sheets from the first conveyor body to the second conveyor body.

1. A transport mechanism for transporting sheets of a print medium along a transport path in a printing system, comprising:
a first conveyor device having a first conveyor body which is configured to hold a plurality of sheets of print medium and is movable to convey the sheets along the transport path; and a transfer system comprising a second conveyor device having a second conveyor body which is configured to hold the sheets and is movable to convey the sheets further along the transport path, wherein the transfer system is configured to transfer the sheets from the first conveyor body to the second conveyor body in a transfer region, wherein the second conveyor body is arranged adjacent the first conveyor body in the transfer region, and the transfer system is configured to provide a second under-pressure at the second conveyor body arranged for contactless transfer of the sheets from the first conveyor body to the second conveyor body, wherein the second conveyor body has a second carrier surface configured to support the sheets thereon, and wherein the second conveyor device provides regions on the second carrier surface of different air-flow from the second under-pressure, the second carrier surface including a region of relatively higher suction force or air-flow arranged in a central region of the second carrier surface with respect to the transport path arranged for attracting a centre portion of the each sheet with respect to the transport path towards the second conveyor body in the transfer region.
