Abstract

The invention relates to a device and a method for handling a metal strip. The device comprises a coiling device ( 110 ) with a coiling mandrel ( 112 ) for winding the metal strip to form a coil ( 200 ) on the coiling mandrel and a coil stripper car ( 120 ) with supports ( 124 ) for receiving the coil ( 200 ) from the coiling mandrel and removing the coil from the coiling device ( 110 ). In order to additionally secure the metal strip in the coiling device during the transfer from the coiling mandrel onto the coil stripper care and during a transport by means of the coil stripper car, a first hold-down arm ( 130 ) is provided for exerting a first hold-down force (F 1 ) onto the outer circumference of the coil ( 200 ) in order to press the coil onto the supports of the coil stripper car.

First claim

The invention claimed is:

1. Device ( 100 ) for handling a metal strip, with a coiling device ( 110 ) with a coiling mandrel ( 112 ) for winding the metal strip to the form of a coil ( 200 ) on the coiling mandrel;
and
with a coil stripper car ( 120 ) with supports ( 124 ) for receiving the coil ( 200 ) from the coiling mandrel and removing the coil from the coiling device ( 110 );
and
a first hold-down arm ( 130 ) for applying a first hold-down force (F 1 ) with at least one component in direction of the gravity force to an outer circumference of the core at a mid-plane of the coil for pressing the coil onto the support of the coil stripper car,
characterized by
a second hold-down arm ( 150 ) for applying a second pressure force (F 2 ) with its coil-side end in the eye of the coil ( 200 ), wherein the second hold-down arm ( 150 ) is designed so that it is set in the eye of the coil ( 200 ) in such a manner that the second hold-down force (F 2 ) applied by the second hold-down arm in the eye of the coil has at least one component in the direction of the gravity force.

2. Device ( 100 ) according to claim 1 ,
characterized in that
that an overhang beam ( 133 ) is provided, which is arranged above a path for the coil stripper car, particularly above a fixed track configuration ( 122 ),
that a trolley ( 135 ) is provided for holding the first hold-down arm ( 130 ) and for moving together with the hold-down arm ( 130 ) on the overhang beam ( 133 ); and
that a synchronization device is provided for synchronizing the movement of the trolley ( 135 ) with the first hold-down arm and of the coil stripper car in such a manner that the first hold-down arm ( 130 ), during the movement of the coil stripper car, is applied onto the outer circumference of the coil.

3. Device ( 100 ) according to claim 2 ,
characterized in that
the synchronization device is designed in the form of an electronic control ( 140 ) or in the form of a mechanical coupling of the coil-side end ( 131 ) of the hold-down arm to the coil.

4. Device ( 100 ) according to claim 2 ,
characterized in that
the overhang beam ( 133 ) is anchored with one end fixed in or on the area of the coiling device ( 110 ).

5. Device ( 100 ) according to claim 1 ,
characterized in
that the first hold-down arm ( 130 ) is coupled mechanically by means of its end away from the coil to the coil stripper car ( 120 ).

6. Device ( 100 ) according to claim 1 ,
characterized in that
the first hold-down arm ( 130 ) is designed so it can be moved in and out telescopically.

7. Device ( 100 ) according claim 6 ,
characterized in that
the second hold-down arm ( 150 ) is attached by means of its end away from the coil eye to the coil stripper car ( 120 ) or to an additional coil car ( 160 ).

8. Device ( 100 ) according to claim 1 ,
characterized in that
the first and/or second hold-down arms ( 130 , 150 ) is/are designed so they/it are/is height adjustable.

9. Method for handling a metal strip, with the following steps:
winding the metal strip to form a coil ( 200 ) on a coiling mandrel ( 112 ) of a coiling device ( 110 );
transferring the coil ( 200 ) from the coiling mandrel to a coil stripper car ( 120 );
removing the coil on the coil stripper car from the coiling device;
applying a first hold-down force (F 1 ) with at least one component in direction of the gravity force to the outer circumference of the coil ( 200 ) with a first hold-down arm ( 130 ) for pressing the coil ( 200 ) onto the coil stripper car ( 120 ) during the transfer of the coil from the coiling mandrel onto the coil stripper car, and while the coil is being removed from the coiling device ( 110 ),

characterized by
applying a second down force (F 2 ) with at least one component in direction of the gravity force in the eye of the coil using a second hold-down arm for pressing the coil on the supports of the coil stripper car, after the coil on the coil stripper car has been removed at least some distance from the coiling device, and before the end of the range of the first hold-down arm has been reached, and
removing the first hold-down arm ( 130 ) from the coil ( 200 ) after the second hold-down arm ( 150 ) engages in the eye of the coil ( 200 ).

10. Method according to claim 9 ,
characterized in that,
while the coil on the stripper car ( 120 ) is being removed from the coiling device ( 110 ), at least the coil-side end of the first hold-down arm ( 130 ) is also moved synchronously with the coil and the coil stripper car.

11. Method according to claim 9 ,
characterized in that
the coil ( 200 ) on the coil stripper car ( 120 ) is transported further to at least one coil binding machine, which is arranged, for example, outside of the range of the first hold-down arm ( 130 ).

12. Method according to claim 9 ,
characterized in that
an additional coil car ( 160 ), on which the second hold-down arm ( 150 ) is anchored by means of its end away from the coil, is moved synchronously with the coil stripper car ( 120 ) for the purpose of maintaining the second hold-down force (F 2 ) by the second hold-down arm ( 150 ) in the eye of the coil ( 200 ) during the further transport.

13. Method according to claim 9 ,
characterized by
binding the coil in the coil binding machine and releasing the second hold-down force by removing the second hold-down arm ( 150 ) from the eye ( 210 ) of the coil ( 200 ).

14. Method according to claim 9 ,
characterized in that
the first hold-down arm ( 130 ) is adjusted in terms of its height so that it can exert the first hold-down force (F 1 ) onto the outer circumference of the coil ( 200 ); and/or
the second hold-down arm is adjusted in terms of its height so that it can exert the second hold-down force in the eye ( 210 ) of the coil ( 200 ).
