Abstract

PROBLEM TO BE SOLVED: To rotate a cylindrical roll and to extract/retract a wound material by installing multiple rotatable cylinders in contact with the outer peripheral portion of a cylindrical roll partially or wholly. SOLUTION: Multiple rotatable cylinders 1 are arranged at intervals in no contact with an outer frame 3 so that part or all of multiple rotatable cylinders 1 are kept in contact with the other periphery of a cylindrical roll 2. Multiple rotatable cylinders 1 are rotated by the rotation of the cylindrical roll 2 or the rotation of part or all of multiple rotatable cylinders 1 in response to the extracting/retracting action of the material wound on the cylindrical roll 2. The wound material is moved in the direction of the motion generated by the rotation of multiple rotatable cylinders 1 by a series of continuous motions.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention uses a plurality of cylinders which can be rotated by mounting a shaft at the center of the circumference on the side of the cylinder or by using a ball bearing such as a bearing or a ball bearing, Multiple cylinders (Figure 1
Using each of the rotations of 1, 2, 3, 4, 5, 6, 7), the shape of the rolled material is cylindrical (FIGS. 2A and 2).
B) and those having a frame having a circumference on the side of the rolled material (FIGS. 2C, 2D, 2E), (the shape of the rolled material being cylindrical and the frame having a circumference on the side of the rolled material) Is called a column-shaped scroll.) When a plurality of rotatable cylinders are rotated, a plurality of rotatable cylinders (Fig. 1-8) are rotated. Utilizing a plurality of rotatable cylinders that allows the rolled material to move by a series of continuous movements of the rotatable cylinder.

[0002] A plurality of rotatable cylinders mounted on a scroll pulling-in device are brought into contact with the outer periphery of the cylindrical scroll so that when the rolled material is extracted from the columnar scroll and when the rolled material is rolled out. When rolling in, a part or all of the plurality of cylinders set in the scroll pull-in device rotate to rotate the rolled material, pull out the rolled material, and roll in the rolled material Has become.

[0003] The present invention allows a plurality of rotatable cylinders of a roll unwinder to be moved (Fig. 3) to accommodate changes in the circumference and size of a cylindrical roll. To

[0004] The present invention allows the outer frame on which a plurality of rotatable cylinders is installed to be movable (FIGS. 4A and 4B) so as to cope with the change in the circumference and the size of the cylinders. It can be so.

According to the present invention, the outer frame on which a plurality of rotatable cylinders are installed is divided (FIGS. 5A and 5B) or opened and closed (FIGS. 6A and 6B). Make it possible to combine.

[Industrial applications]

[0006] The present invention is used for drawing out a cylindrical rolled material and for rolling up a rolled material.

[0007] The present invention is used for drawing cylindrical rolled paper, cloth, cloth, synthetic fiber, synthetic paper, synthetic resin and metal foil, and for winding these rolls.

The present invention is used for drawing out a thread, a rope, a rope, a string, a chain, and a wire wound on a winding frame having a circumference, and for winding these wound materials.

[Prior art]

When the cylindrical roll is rotated and the rolled material is extracted or the rolled material is rolled up, the central portion of the cylindrical roll has an axis which allows the cylindrical roll to rotate. By setting a cavity through which the shaft is passed, the cylindrical scroll is rotated through the shaft, and the wound material is drawn out or the wound material is involved.

[0010] A shaft for rotating a cylindrical roll or a cavity passing through the shaft has a single fulcrum.

[Problems to be solved by the invention]

[0011] It is a problem to rotate a cylindrical roll to draw out the rolled material and to roll up the rolled material without using a shaft or a hollow through which the cylindrical roll can be rotated. Was.

It has been a problem to cope with a change in the circumference of a cylindrical roll and the magnitude of the circumference.

[0013] With respect to a heavy columnar roll, it has been a problem to support and rotate a roll that exceeds the weight supported by a uniaxial fulcrum.

[Means for Solving the Problems]

By installing a plurality of rotatable cylindrical parts in contact with part or all of a plurality of rotatable cylinders on the outer peripheral portion of the circumference of the cylindrical scrolls, the cylindrical scrolls are rotated, and the rolled material is removed. The material can be drawn or rolled up.

[Action]

According to the present invention, a part or all of a plurality of rotatable cylinders are brought into contact with the outer periphery of a cylindrical scroll at such an interval that each of the plurality of rotatable cylinders does not touch each other. In accordance with the operation of pulling out the material wound on the cylindrical roll or involving the rolled-up material by rotating the cylindrical roll or rotating a part or all of the cylindrical shape that can rotate a plurality of times,
Each of the plurality of rotatable cylinders rotates and makes a series of continuous movements, so that the wound material or the material to be wound moves in the direction of the movement caused by the plurality of rotatable cylinders. I do.

Embodiment 1

[0016] A cylindrical toilet paper is placed on a scroll pull-in device (Fig. 7), and the end of the rolled toilet paper is held and a plurality of rotations in contact with the outer periphery of the toilet paper when trying to pull out the toilet paper. By rotating simultaneously with the rotation of the toilet paper that starts to rotate by the force that tries to pull out the toilet paper, the toilet paper can be pulled out.

Embodiment 2

When pulling out a rolled material from a long cylindrical scroll such as a piece of cloth, or when rolling in a rolled material, a scroll pulling-in / retracting device is attached to a desk or a cutting table to pull out or roll in a long cylindrical roll such as a piece of cloth. be able to.

Embodiment 3

A scroll pull-in / retract device in which the outer frame can be changed so as to be able to cope with a change in the diameter of the cylindrical scroll to be installed or the size of the diameter.

Embodiment 4

In order to correspond to the width of the winding frame having a circumference,
Use more than one scroll drawer and retractor.

For a long cylindrical scroll, a plurality of scroll pull-in / roll-in devices are used.

Embodiment 5

In order to install a heavy material such as an electric wire wound around a reel on a scroll pull-in device (FIG. 5A,
5B) Divide the scroll pull-in device, attach a heavy material, and join the divided portions.

Embodiment 6

It is used when pulling out or winding a fishing reel line (FIGS. 6A and 6B).

Embodiment 7

【The invention's effect】

Rotating a cylindrical roll without drawing the center of a surface having a circumference on the side of the cylindrical roll as the axis of rotation when pulling out or rolling up the rolled cylindrical material. Can be.

The weight of a cylindrical scroll can be distributed over a plurality of axes by means of a plurality of rotatable cylinders, so that the heavier weight of a cylindrical scroll can be supported than supported by a single axis. Can be rotated.

By changing the position at which a plurality of rotatable cylinders are installed or by changing the outer frame, it is possible to cope with a change in the circumference of a cylindrical scroll or a change in the size.

By being able to be divided or opened and closed, it is easy to install a cylindrical scroll.
