Coiler device for rolled strip
View Patent ↗The invention relates to a coiler device for a rolled strip comprising at least one driven troughed roller ( 1 ) for rotating a coil ( 2 ) during the coiling and uncoiling of a rolled strip, in addition to a roller line located upstream or downstream of the coil. According to the invention, the troughed roller ( 1 ) is configured with an elastically deformable outer collar ( 4 ).
1. Coiler for rolled strip, which comprises at least one driven troughed roller ( 1 ) for turning a coil ( 2 ) during coiling or uncoiling of a rolled strip and a roller table upstream or downstream from the coiler, wherein the troughed roller ( 1 ) is designed with an elastically deformable outer collar ( 4 ), wherein the outer collar is uniformly supported by support members that are spring-tensioned from the inside by disk springs against the outer collar.
2. Coiler in accordance with claim 1 , wherein the troughed roller ( 1 ) has a bearing surface ( 3 ) formed by a series of adjoining outer collars ( 4 ) of different diameters, which surround a core ( 5 ) of the troughed roller ( 1 ) so that they act on a contact surface ( 7 ) of the troughed roller ( 1 ) with the coil ( 2 ) over its entire longitudinal extent with uniform contact pressure.
3. Coiler in accordance with claim 2 , wherein the support members ( 6 ) are designed with curved contact surfaces to adapt them to the inner circumference of the outer collars ( 4 ).
4. Coiler in accordance with claim 2 , wherein the back of each support member ( 6 ) is lined with a set of disk springs ( 8 ) with predeterminable pretensioning.
5. Coiler in accordance with claim 2 , wherein the support members ( 6 ) are mounted in the outer collars ( 4 ) with pretensionable spring force.
6. Coiler in accordance with claim 1 , wherein to compensate a load-related flexure of the troughed roller ( 1 ), which can be calculated or empirically determined, the outside diameters of the outer collars ( 4 ) increase towards the middle of the troughed roller ( 1 ).
7. Coiler in accordance with claim 1 , wherein adjoining outer collars ( 4 ) are provided with an oblique transition to the adjacent outer collars ( 4 ).
8. Coiler in accordance with claim 1 , wherein the bearing surfaces of the outer collars ( 4 ) are designed with a slight camber ( 9 ), which, however, does not exceed the magnitude of the difference in diameters.
9. Coiler in accordance with claim 1 , wherein two troughed rollers ( 1 , 1 ′) that can be arranged with a predeterminable axially parallel separation act together to support the load of the coil ( 2 ).
10. Coiler in accordance with claim 9 , wherein at least one of these troughed rollers ( 1 ) has a rotational drive.
11. Coiler in accordance with claim 1 , wherein the troughed roller ( 1 ) comprises
a solid central shaft ( 5 ),
a middle collar ( 11 ) on the shaft ( 5 ) for holding support members ( 6 ) that can be spring-tensioned, and
an outer collar ( 4 ) with an outer support collar ( 12 ) for supporting the load.
12. Coiler in accordance with claim 1 , wherein a contact surface ( 7 ), especially concave contact surface ( 7 ), that forms on a coil during the uncoiling can be automatically adapted to the usually cambered circumference of the coil ( 2 ) by means of the elastically yielding outer collars ( 4 ).
