Abstract

The invention relates to a device for winding a strip material into a coil. The device comprises a winding mandrel ( 1 ) having a shaft element ( 2 ) and radially movable segments ( 16 ) mounted on the shaft element for winding and unwinding the strip material. The device further comprises an actuating drive ( 26 ) for spreading or collapsing the segments. The device also has a rotary drive ( 5 ) for rotationally driving the winding mandrel. To achieve a simpler and more economical design, a displacement device ( 60 ) is provided for axially displacing the actuating drive ( 26 ) together with the winding mandrel ( 1 ).

First claim

The invention claimed is:

1. A device for winding a strip material into a coil, comprising a single winding mandrel ( 1 ) having a shaft element ( 2 ) and radially displaceable segments ( 16 ) mounted on the shaft element ( 2 ) for winding the strip material onto the segments;
an actuation drive ( 26 ) for displacing the segments ( 16 ) relative to the shaft element ( 2 ) with actuation elements ( 29 ) either further radially outwardly or further radially inwardly; and
a rotary device ( 5 ) for rotationally driving the single winding mandrel, wherein the actuation drive ( 26 ) and the rotary device ( 5 ) are arranged on axially opposite end sides of the single winding mandrel ( 1 ),
wherein
a displacement device ( 60 ) is provided for an axial displacement of the actuation drive ( 26 ) together with the single winding mandrel ( 1 ).

2. The device according to claim 1 ,
wherein
an actuation drive side thrust bearing and a rotary drive side thrust bearing ( 52 , 54 ) are provided for axially and rotationally supporting the shaft element ( 2 ) at the both ends thereof.

3. The device according to claim 2 , wherein the rolling drive side bearing ( 54 ) is formed as a coupling bearing for releasably connecting and disconnecting the shaft element ( 2 ) to and from the rotary drive ( 5 ).

4. The device according to claim 3 , wherein the shaft element ( 2 ) has, on the side of the rotary drive ( 5 ), a rotary drive journal section ( 8 ) that fixedly but releasably connects the shaft element with an output shaft of the rotary drive ( 5 ).

5. The device according to claim 4 , wherein the coupling bearing ( 54 ) is formed as a flat, or a spline bearing and journal bearing the rotary drive journal section ( 8 ) is formed as a flat journal or a spline journal cooperating with the flat journal bearing or the spline bearing.

6. The device according to claim 1 , wherein the actuation drive ( 26 ) is axially arranged adjacent to the radially displacement segments ( 16 ) for directly controlling the segments ( 16 ) with the actuation elements ( 29 ).

7. The device according to claim 6 , wherein the actuation drive ( 26 ) actuation elements ( 29 ) are interposed between and the radially displaceable segments ( 16 ).
