Method, holding means, apparatus and system for transporting a flat material to be treated and loading or unloading apparatus
View Patent ↗In order to transport a flat material to be treated ( 21 ) in an installation for the chemical and/or electrochemical treatment of said material, within which the material to be treated ( 21 ) is transported within a plane of transport in a direction of transport ( 5 ), holding means ( 22, 25 ) are attached to said material to be treated ( 21 ). The holding means ( 22, 25 ) hold the material to be treated ( 21 ) at at least two points on an edge region of said material, which edge region is directed along the direction of transport ( 5 ) when said material to be treated ( 21 ) is being transported. The holding means ( 22, 25 ) are coupled in a detachable manner to a transporting device ( 41 ) which moves said holding means ( 22, 25 ) in the direction of transport in order to transport the material to be treated ( 21 ). At least during a portion of the transportation of the material to be treated ( 21 ), a force ( 6, 7 ) having a component which lies within the plane of transport and is directed transversely to the direction of transport ( 5 ), is exerted upon a region of the material to be treated ( 21 ), for example upon the longitudinal edge regions.
1. Device for transporting a flat material to be treated, which is mounted along an edge region by means of holding means, for an installation for the chemical and/or electrochemical treatment of said material to be treated, wherein said device is set up so as to transport the material to be treated within a plane of transport in a direction of transport, said device comprising:
transporting means coupled to the holding means in a detachable manner and which are configured to move said holding means, with the material to be treated mounted thereon, in the direction of transport; and
tensioning means for exerting, upon the holding means, a force which is directed within the plane of transport and transversely to the direction of transport, the tensioning means comprising:
a movable bearing to guide the holding means; and
at least one magnet in order to exert a force on the movable bearing transversely to the direction of transport,
wherein the device is configured to exert, at least during a portion of the transportation of the material to be treated, a force having a component which lies within the plane of transport and is directed transversely to the direction of transport, upon at least one region of the material to be treated.
2. Device according to claim 1 ,
wherein the transporting means comprise a driving shaft to which the movable bearing is attached.
3. Device according to claim 1 ,
wherein said device is configured to transport the material to be treated which is mounted along a further edge region by means of further holding means,
wherein said device comprises further tensioning means which are configured to exert, upon said further holding means, a force which is directed within the plane of transport and transversely to the direction of transport.
4. A system for transporting a flat material to be treated for an installation for the chemical and/or electrochemical treatment of said material to be treated, said system comprising:
holding means configured to be coupled to the edge region of the material to be treated, wherein the holding means comprise a holding rail in which passages for a liquid are formed; and
a device to transport the material to be treated within a plane of transport in a direction of transport, said device comprising:
a transport mechanism coupled to the holding means in a detachable manner, the transport mechanism configured to move said holding means, with the material to be treated mounted thereon, in the direction of transport; and
tensioning means for exerting, upon the holding means, a force which is directed within the plane of transport and transversely to the direction of transport, the tensioning means comprising:
a movable bearing to guide the holding means; and
a bias mechanism to exert a force upon the movable bearing transversely to the direction of transport.
5. A system according to claim 4 , further comprising:
a loading or unloading apparatus for the installation for the chemical and/or electrochemical treatment of the material to be treated,
wherein the loading or unloading apparatus is set up so as to transfer the holding means between a closed condition for holding the material to be treated and an open condition, and comprises a supporting apparatus for supporting said material to be treated when the holding means are transferred into the open condition.
6. A system according to claim 5 , wherein the loading or unloading apparatus is configured to receive the holding means in the closed condition, transfer them from the closed condition into the open condition and then back into the closed condition, and to pass them out in the closed condition.
7. A system according to claim 4 , wherein the holding means are detachably coupled to the transporting means.
8. A system according to claim 4 , wherein the holding means extend along the direction of transport on the edge region of the material to be treated.
9. A system according to claim 4 , wherein the holding means comprise a first holding part and a second holding part, the first and second holding parts having a closed condition for mounting the material to be treated and an open condition for insertion of the material to be treated.
10. A system according to claim 9 , wherein the first and second holding parts are coupled to the material to be treated in a force-locking connection.
11. The device of claim 1 , wherein the holding means comprise a holding rail in which passages for a liquid are formed.
