And a cutting means for cutting the slices.

(Operation) Therefore, a series of devices for mounting the paper tube, winding the raw tape on the paper tube, cutting the winding end of the raw tape, cutting the raw tape and removing the raw tape. Can be performed in a series of steps.

This does not require separate equipment for each step and does not require a large space.

Further, it is possible to efficiently manufacture a tape.

(Example) Hereinafter, an example of a tape manufacturing method and a tape manufacturing apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic front view of a tape manufacturing apparatus according to the present invention, FIG. 2 is an explanatory view of a drive mechanism thereof, FIG. 3 is an enlarged front view of a cutting means showing a state before cutting a tape raw material, FIG. 4 is an enlarged front view showing a state where the raw tape is cut.

The manufacturing apparatus 1 includes a rotating body 2 that is rotated in one direction,
A plurality of (six in this embodiment) rotating shafts 3 arranged at predetermined intervals around the circumference of the rotating body 2, and a raw tape wound around a paper tube S mounted on the rotating shaft. End cutting means 4 for cutting the end portion of T; and a tape raw material T which is arranged on the rotation direction front side of the rotating body 2 with respect to the end cutting means 4 and whose end is cut and wound, is cut together with the paper tube S into a round slice. Two slice cutting means 5, 5 are provided.

 The rotating body 2 has a disk shape.

Note that the rotating body 2 is not limited to a disk-shaped one, and may be, for example, one in which a plurality of plates or bars are radially extended from a shaft in a radial direction.

The rotating body 2 is rotated by rotating means such as a motor (not shown).
It is rotated in one direction (counterclockwise in the figure).

By rotating the rotating body 2 in one direction, the rotating shafts 3.
Is rotated in the rotation direction of the rotating body 2.

 The rotating shafts 3 are separately driven to rotate.

The rotational drive structure of the rotating shafts 3 is as shown in FIG.

That is, the first for driving the gear 31 of the rotating shafts 3.
The drive gear 6a, the second drive gear 6b, the third drive gear 6c, and the fourth drive gear 6d wind a portion where the raw tape T is wound and the raw tape T whose end is cut by the end cutting means 4. The positions are fixed and fixed so as to be rotatable at a place where the tape material T is to be cut and a place where the tape material T is cut.

The first drive gear 6a and the second drive gear 6b are rotationally driven by separate motors 7a, 7b via chains 8a, 8b.

Another indirect gear 9 is disposed between the third drive gear 6c and the fourth drive gear 6d, and the chain 8c is driven by one motor 7c.
Is driven to rotate.

The end cutting means 4 has a wide cutting blade (not shown).

The end cutting means 4 rotates the rotating body 2 in a state where the raw tape T is wound around the paper tube S, and rotates the gear of the rotating shaft 3.
The tape 31 is moved to a position where it meshes with the second drive gear 6b, and is moved inward from the outside of the rotary shaft 2 in a state where the end of the raw tape T is stretched.

At the time of this movement, the distal end of the raw tape T is cut by the cutting blade.

At the position of the second drive gear 6b, the end of the raw tape T after cutting is wound by the rotation of the rotary shaft 3 and the pressing action by the pressing roll 20.

On the other hand, the starting end of the raw tape T after cutting is pressed against the surface of the next paper tube S by the end cutting means 4,
The next rotation of the rotating shaft 3 at the position of the first drive gear 6a winds up the paper tube S.

A plurality of rotating plates 52 are arranged and fixed at predetermined intervals in the axial direction of a rotating shaft 51 rotatably arranged at a fixed position.
52. The positions of the cutting blades 53 in the circumferential direction are shifted by a certain angle in the circumferential direction.

As shown in FIG. 2, these wheel cutting means 5 are driven to rotate in the same direction by one motor 10 via two chains 11, 11, respectively.

It is not always necessary to provide two ring cutting means 5, 5, and one or three or more pieces may be provided.

Next, a method of manufacturing a tape according to the present invention using the manufacturing apparatus having the above structure will be described.

The manufacturing method starts with a step of mounting a paper tube S on a plurality of rotating shafts 3 arranged at predetermined intervals around the circumference of a rotating body 2.

Next, there is a step of winding the raw tape T around the paper tube S of the rotating shaft 3 which has been rotated by a predetermined angle in the circumferential direction of the rotating body 2 with the paper tube S mounted.

Next, with the raw tape T wound on the paper tube S, the end of the raw tape T of the rotating shaft 3 that has been rotated by a predetermined angle in the circumferential direction of the rotating body 2 is cut by the end cutting means 4. There is a process of winding up.

Next, the rotating shaft 3 which is rotated by a predetermined angle in the circumferential direction of the rotating body 2 in a state where the raw tape T is wound around the paper tube S.
Cutting means 5, 5
There is a step of cutting in a circle.

Next, the process is completed in which, in a state in which the raw material tape T is cut into a slice, the raw material tape T having been cut together with the paper tube S is extracted from the rotating shaft 3 that has been rotationally moved by a predetermined angle in the circumferential direction of the rotating body 2. .

Therefore, mounting of the paper core S, winding of the raw tape T onto the core S, cutting of the winding end of the raw tape T, cutting of the raw tape T, and extraction of the raw tape T Can be carried out in a series of steps with a series of devices.

This does not require separate equipment for each step and does not require a large space.

Further, it is possible to efficiently manufacture a tape.

Further, in this embodiment, a plurality of rotating plates 52 arranged and fixed at predetermined intervals in the axial direction of a rotating shaft 51 rotatably arranged in a fixed position are respectively provided with rotating plates 52.
.. Are cut in a circumferential direction by a predetermined angle and are attached with narrow flat cutting blades 53.
Since the raw material tape T is cut into a slice, there is an advantage described below.

That is, as shown in FIG. 3 and FIG. 4, when the raw tape T is cut into round slices, only the narrow flat cutting blade 53 is in contact with the cut surface of the raw tape T. Therefore, the frictional resistance is very small, and the round cutting can be smoothly performed.

(Effects of the Invention) As described above, according to the present invention, the mounting of the paper tube, the raw tape and winding on the paper core, the cutting of the winding end of the raw tape, and the cutting of the raw tape are performed.
