Coiled sheet rolls changing device in coiling machine - has two pivoting frames with pivot arms alternatively changing winding sleeves

摘要

The two pvoting frames each have two arms pivotably mounted. The free ends of the arms carry one winding sleeve each and the winding sleeves are pivoted by the arms from a winding position on a pull off roller in a removing position. Both pivoting frames (5, 6) are positioned on the same side of the pull-off roller (2) and their pivoting axes (7, 8) are so arranged opposite each other that the winding sleeves carried by the pivoting arms (5, 6) are pivoted in the same winding position on the pull-off roller (2). - The circles (22, 23) traced by the pivoting frames (5, 6) intersect each other in one or two points. The pivoting axes (7, 8) of the pivoting arms (5, 6) are located in a vertical plane parallel to the axis of the pull-off roller (2) and winding position and in the removing position are the same.
