System element for the transporting and positioning of tools

1. A system element for the transporting and positioning of a tool on a surface of a workpiece, comprising

at least one suction device that generates a suction stream; and

a transport device that is arranged around the suction device, the transport device having at least two rollers that are rotatably supported on the suction device, and connection elements that interconnect end regions of the rollers; wherein the rollers and the connection elements are elastically deformable, and the system element substantially conforming with the surface of the workpiece where there is a suction stream.

2. The system element of claim 1 , wherein the rollers and the connection elements contact lateral walls of the suction device.

3. The system element of claim 1 , wherein an advance of the system element takes place by a torque applied to at least one of the rollers.

4. The system element of claim 1 , wherein at least one of the connection elements designed as a running belt that connects two of the rollers at the end regions of the two rollers.

5. The system element of claim 4 , wherein pulleys are arranged at least on one of the end regions of the rollers, the pulleys being rigidly connected to the rollers, and the running belt being placed around the pulleys for transmitting a torque to the rollers.

6. The system element of claim 4 , wherein a torque is applied directly to at least one axle of the rollers or to at least one running belt or both.

7. The system element of claim 1 , wherein a surface of the suction device that is defined by opposite lateral walls of the suction device and that faces away from a suction side of the suction device, is formed quadrangular,

wherein one of the rollers is arranged on the opposite lateral walls of the suction device, and

the end regions of the rollers are connected to each other by a running belt.

8. A transport system comprising a plurality of system elements of claim 1 .
