Description

  The present invention relates to a take-up roll carry-out method and a take-up roll carry-out apparatus for a sheet split take-up device for carrying out a plurality of take-up rolls formed on two take-up shafts arranged at upper and lower take-up positions.

  In order to form a plurality of winding rolls on two winding shafts, a plurality of strip-shaped sheets obtained by dividing a wide strip-shaped sheet into a plurality of strip-shaped sheets having a required width by a slitter in a sheet split winding device. Are alternately distributed to two winding shafts in the order in which the belt-like sheets are arranged in the width direction, and wound around a tubular core for each belt-like sheet that is penetrated and supported by the winding shaft.

  In the conventional take-up roll carrying-out method of the sheet split take-up device, as disclosed in the following Patent Document 1, a carriage provided with a common base for the take-up roll for each winding axis so that it can be moved up and down is advanced. After the cradle has entered the lower side of the winding roll on the winding shaft, the cradle is raised and the lower part of the outer peripheral surface of the winding roll is received by the cradle. After removing in the axial direction, the carriage is moved backward.

  However, when the outer periphery of the take-up roll is received and carried out by the cradle, the contact portion of the outer peripheral surface of the take-up roll with the cradle receives a pressing force from the cradle. Further, the winding roll on the pedestal tends to move together with the winding axis moving in the axial direction when the winding shaft is extracted, and the winding roll tends to roll on the cradle during carry-out. Therefore, the outer peripheral surface of the take-up roll and the cradle are rubbed and the outer peripheral surface of the take-up roll is likely to be damaged. In particular, when the belt-like sheet to be wound is easily scratched on the surface, such as a plastic film with a coating on the surface, and the wound greatly affects the quality of the winding roll, the problem is that the yield decreases. Occurs.

In general, due to uneven thickness of the belt-like sheet, even if a plurality of winding rolls are wound at the same time, there is a slight difference in the radius of each winding roll. In that case, when a plurality of winding rolls formed on one winding shaft are received by a common receiving base, the lifting force of the receiving base concentrates on the winding roll having a large radius, and an excessive pressing force is applied, thereby increasing the radius. The outer surface of the small take-up roll rises from the cradle. When the winding shaft is pulled out, the winding roll falls by the amount lifted from the upper surface of the cradle, so that it is difficult to avoid scratches on the outer peripheral surface of the winding roll. Therefore, before removing the winding shaft from the winding position, each winding roll must be properly supported according to its radius, and for that purpose, a stand that is raised and lowered individually for each winding roll. And the height of each cradle needs to be adjusted according to the radius of the winding roll. Accordingly, the take-out operation of the take-up roll becomes very troublesome, the take-up roll carry-out device becomes complicated, and the take-up roll carry-out device becomes more complicated and larger.
