Claims

[Scope of Claim for Utility Model Registration] When winding up a sheet material such as paper, plastic, aluminum foil, copper foil, etc. onto a paper tube, or when unwinding the sheet material wound around a paper tube, the end of the paper tube In the paper tube holding device for holding the paper tube by pressing the inner surface of the end portion; Slope core surfaces 15 which are attached or have attachment means 10 for attachment to the drive cylinder piston and which descend forwardly at predetermined angles circumferentially around the periphery 13 of the front portion 12;
A stopper body 5 is fixed to the front end 14 of the lock body 4, and is guided by the slope core 15, and walls 16 on both sides partitioning the slope core 15. , 17, each of which has a plurality of holding claws 6 disposed on each slope core 15, and each of the holding claws 6 has a contact surface 30 in planar contact with the inner circumferential surface 38 of the paper tube. , a compression spring 7 is disposed between the rear end and the mounting flange of the lock body 4,
The paper tube holding device 1, 41 is attached to each end 3 of each paper tube 2.
As the paper tube 2 is inserted and its both ends 3 are pressed, the plurality of holding claws 6 are guided by the slope core 15 and protrude in the radial direction to press and hold the paper tube 2 in a planar manner from the inner surface of each end 3 of the paper tube 2. Furthermore, each end surface 3 of the paper tube 2 is held by the end portion 31 of the holding claw 6.
A paper tube holding device characterized by simultaneously holding a paper tube.
