BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet winding apparatus which winds up a sheet to be continuously fed at a terminal of a sheet production line made of synthetic resin, paper, fabric, or the like and winds up the sheet.

Generally, a synthetic resin sheet heats and melts a pellet of a thermoplastic resin in an extruder, and pushes it continuously from a T-shaped pedestal into a sheet form, and winds up the cold-cured sheet | seat by the winding machine at the end of a traveling process, and a required diameter Let's use cold trolls. For example, as shown in FIG. 20, the winding inserts the paper tube P as the winding core into the winding shaft 2 of the winding machine 1, and ends the end of the sheet S in the paper tube P. The take-up shaft 2 wound up by winding by winding the take-up shaft 2 by rotation, and pulled out from the take-up machine 1 by stopping the take-up shaft 2 at the step of reaching the required winding amount is wound around the take-up shaft 2. ) Is pulled out integrally with the paper tube (P). Moreover, as this winding machine 1, a pair of winding shafts 2 and 2 are provided in the both ends of the main swing arm 4 which can be wound around the pivot axis 3, The winding of the sheet S can be continued with the other winding shaft 2 during the operation of removing the winding sheet R as described above with the winding shaft 2 on the side. 5 is guide rolls provided in the both ends of the secondary swing arm 6 orthogonally arranged with respect to the main swing arm 4.

As the winding shaft 2, an air shaft is used for general purposes. As shown in Fig. 21 (A), the air shaft has a plurality of radially arranged on the outer circumferential surface of the metal tube shaft 21 in which the short slit-shaped windows 21a are formed along the axial direction on the circumferential surface thereof. The rubber tube 22 provided with the short field-like lag protrusion 22a ... along the axial direction of the said lag protrusion 22a is fitted to the said slit-shaped window part 21a, and this rubber | gum is The internal pressure of the tube 22 can be increased or decreased, and each lag protrusion 22a enters and exits the slit-shaped window part 21a by expansion and contraction of the rubber tube 22 according to the increase and decrease of the internal pressure.

Therefore, in winding the sheet S, the paper tube P is inserted into the movable shaft 2 in which the lag projections 22a are retracted in a movable state, and then the internal pressure of the rubber tube 22 is increased. As shown in Fig. 21B, the rag projections 22a are pressed against the inner circumferential surface of the paper tube P to join the paper tube P so as to be integrally rotatable with the take-up shaft 2. Keep it. Then, after winding the required amount of the sheet S in this state, the internal pressure of the rubber tube 22 is lowered to release the pressing of the lag protrusions 22a...
