Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a core extracting device for a paper roll, and in particular, the unwound paper (generally referred to as a side run) which is the remaining portion when the paper roll is cut into a predetermined width. Existing) is the device for pulling out the core.

[Prior Art] The remaining side run when the paper roll is cut to a predetermined width is disintegrated by a pulper and then sent to a preparation step for reuse.

Conventionally, in the side run, without pulling out the core, with the core attached, pass the wire rope inside the core,
They are hoisted, piled up sequentially on a transport pallet, and after removing the wire rope, they are transferred to the waste paper room. In the waste paper room, the side run is cut with a cutter knife or the like to remove the core.

[Problems to be solved by the present invention] However, in the conventional method, the paper is cut from the outside with a cutter knife or the like to be loosened, and then the core is removed, which is not only complicated but also inefficient.

In addition, since the quality of the side run when the raw material chemicals are drastically changed and the paper is made is different, it cannot be put into the pulper together with other side runs and must be stored temporarily.

However, in the conventional side run, when the core is attached, the end of the core may protrude from the side run in this case, so the shape of the package is unstable when stacked, and the load collapses. Not only is there a risk, but the amount of side runs that can be stacked is also limited.

Therefore, it is desired to pull out the core from the side run, but at present, a device for pulling out the core from the paper roll such as the side run has not been developed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a device that makes it possible to pull out a core directly from a side run in a wound state and easily store the core afterwards or throw a waste paper into a pulper.

[Means for Solving the Problems] In the present invention, a piston is attached to a cylinder, which has a tip having a thick cone and a piston on the piston side. The piston is attached to the outer periphery of the tip of the piston. Is fitted, and a plurality of rollers are loosely fitted in the stopper seat so as to be free to move outward in the radial direction, and a part of the outermost part of the rollers can project to the outside of the stopper seat. On the other hand, the paper web pressing member is positioned on the outer periphery of the stopper seat and is fixed to the cylinder, and a stopper is attached to the paper web pressing member, so that the stopper seat serves as the paper web pressing member. It is configured to be detachable.

[Operation] The present invention is constructed as described above, and is loosely fitted radially outward in the piston tip portion and the stopper seat, which form a cone with a thick tip and a tapered piston side. The stopper seat is brought into close contact with the core of the side run by the joint operation with the mounted roller, while the joint operation of the piston and the paper-sheet holding member presses the web, while the piston can pull out the core.

Next, the piston 2 is lowered, the tip end portion 3 of the piston rod 2A is inserted into the core K of the side run main body S as shown in FIG. Remove the stopper rod 12 from the engaging portion 5 of the stopper seat 4 as shown in.

When the stopper rod 12 is disengaged from the engaging portion 5, the stopper receiving seat 4 is placed on the upper end surface of the core K as shown in FIG. 2 due to the lowering of the piston rod 2A. In this state, the roller 7 of the stopper seat 4 is located in a loosely fitted state in the space formed by the holding wheel 6 and the piston rod 2A.

Next, the paper holding member 10 is lowered to move the side run main body S
When it is placed on the upper surface and the piston 2 is raised,
As shown in FIG. 3, the stopper seat 4 relatively moves to the lower part of the piston 2, and the roller 7 abuts on the outer peripheral surface of the tip end portion 3.
As shown in the figure, the roller 7 is pressed into the concave portion 8 of the holding wheel 6 as the tip portion 3 rises, and the outermost part of the roller 7 projects from the groove 9 of the holding wheel 6 to the inner peripheral surface of the core K. It bites into and is strongly adhered.

When the piston 2 continues to rise, the side run body S
Is pushed up by the bottom surface of the paper presser member 10, while the core K of the side run main body S is bitten by the roller 7, so that the piston 2 is gradually pulled out from the side run main body S and removed. To be done.

After the core K is removed as described above, when the locking portion 5 of the stopper seat 4 and the stopper rod 12 are at the same height, the handle 13 is rotated in the direction opposite to the arrow and the stopper rod 12 is rotated.
Is engaged with the locking portion 5, and then the piston rod 2A is moved downward, so that the core K is disengaged from the roller 7. Hereinafter, the core K can be pulled out from the plurality of side run main bodies S by sequentially performing the above work.
