Transport device, especially for transporting flat substrates through a coating installation
View Patent ↗The transport device especially for transporting flat substrates through a coating installation comprises a plurality of transporting rolls, which are arranged transversely in relation to the transporting direction, and supporting rolls are also provided.
1. A transport device, especially for transporting flat substrates through a coating installation, comprising
a plurality of transporting rolls arranged transversely in relation to a transporting direction and rotatably mounted on both sides, wherein uppermost surface lines of the transporting rolls define a transporting plane and wherein at least some of the transporting rolls are capable of being driven and
a plurality of supporting rolls are arranged transversely in relation to the transporting direction rotatably mounted on both sides and arranged in a parallel plane lying below the transporting plane
wherein at least in regions in which supporting rolls are arranged, collecting containers for coating material are provided in a space between the supporting rolls and the transporting plane, in a vicinity of ends of the supporting roll.
2. The transport device as claimed in claim 1 , wherein in the transporting direction, no transporting rolls are provided in regions in which supporting rolls are arranged.
3. The transport device as claimed in claim 1 , wherein the transporting rolls and the supporting rolls are of substantially the same length.
4. The transport device as claimed in claim 3 , wherein the transporting rolls and the supporting rolls are mounted on both sides, in a respective common bearing support.
5. A transport device, especially for transporting flat substrates through a coating installation, comprising
a plurality of transporting rolls arranged transversely in relation to a transporting direction and rotatably mounted on both sides, wherein uppermost surface lines of the transporting rolls define a transporting plane and wherein at least some of the transporting rolls are capable of being driven,
a plurality of supporting rolls are arranged transversely in relation to the transporting direction rotatably mounted on both sides and arranged in a parallel plane lying below the transporting plane, and
at least one bridging roll wherein the bridging roll lies in parallel on two supporting rolls and the bridging roll has a diameter chosen such that an uppermost supporting line of the bridging roll lies in the transporting plane.
6. The transport device as claimed in claim 5 , wherein adjacent bridging rolls lie together on the same supporting roll arranged between them.
7. The transport device as claimed in claim 5 , wherein the bridging rolls are shorter than the transporting rolls.
8. The transport device as claimed in, claim 5 wherein the supporting rolls have guiding means for the axial fixing of the bridging rolls.
9. The transport device as claimed in claim 1 , wherein at least some of the supporting rolls can be driven.
10. The transport device as claimed in claim 9 , wherein the transporting rolls and supporting rolls can be driven by a common driving means with a power transmission device.
11. The transport device as claimed in claim 5 , wherein at least some of the supporting rolls can be driven.
