Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper core winding method and a winding core, in which a shaft is inserted into a hollow of the core and rotated to wind the roll paper around the outer periphery of the core. Regarding

[0002]

2. Description of the Related Art As a method of winding a strip-shaped roll paper around a core, there are a method of winding one end of the roll paper by adhering to the core and a method of winding without such adhesion.

The above-mentioned method of adhering the end portion of the roll paper to the core and winding it is based on an axial rotation method in which a shaft is inserted into the hollow of the core and the core is rotated by the rotation of the shaft to wind the shaft. It is necessary to lock the end of the roll to the outer periphery of the core with an adhesive or the like by some means. If this is not done, the end of the roll paper will slip around the outer periphery of the core and spin around, making it impossible to wind.

On the other hand, a method of winding one end of a roll around a core without adhering the roll is by pressing a plurality of rollers onto the outer circumference of the core without depending on the shaft and rotating the core by following the rotation of these rollers. This is based on a surface drive method in which roll paper is wound. In this case, the end of the roll paper that contacts the core rotates while being attached to the outer periphery of the core due to the pressure contact force of the roller, so that the end of the roll paper does not spin around without adhering to the core Be done.

[0005]

However, the roll winding method based on the axial rotation method has an advantage that it can be wound regardless of the type of paper as long as the front end of the roll paper is adhered to the outer periphery of the core. Since the bonded part and its vicinity cannot be used, it is uneconomical.

Further, in various devices, the detection of the paper break of the roll paper is made by an optical method or the like when the final end of the roll paper passes, and the above method of bonding the roll paper to the core is not used. However, there is a drawback in that a piece of paper cannot be detected because the final end does not separate from the core.

On the other hand, in the surface-driving roll winding method, since it is not necessary to bond the roll paper to the core, the roll paper can be economically used, but the roll paper to be wound is limited. For example, tack paper used for handy terminals and the like has a small friction coefficient, so it tends to slip around the core, and the end of the tack paper must be bonded to the outer periphery of the core in order to roll it around the core. Of.

In recent years, such devices as a handy terminal have been downsized and can be used up to the final end of tack paper, and the final end of tack paper is detached from the core in order to detect paper breakage. Thus, there is a demand for a method of winding.

The present invention has been made in view of the above circumstances and has a method in which the final end portion is separated from the core and the winding end portion is formed by some method regardless of the type of paper, such as a surface-driving roll paper. SUMMARY OF THE INVENTION An object of the present invention is to provide a method of winding a core of a roll paper and a winding core that are wound by being locked on the core by the method.

[0010]

In order to solve the above-mentioned problems, the method of winding a core of roll paper according to the present invention is such that the shaft 2 inserted into a core 2 having a hollow 1 is rotated to rotate the core 2. In the method for winding a roll paper core around the outer periphery of the roll paper 4, the non-adhesive portion of the locking paper 5 adhered with one end wound around the outer periphery of the core 2 is released as the tongue piece 6. After the tip of the roll paper 4 is clamped between the outer periphery of the core 2 and the tongue piece 6, the roll 2 is rotated by the rotation of the shaft 3 to move the roll paper 4 to the core. It is characterized in that it is wound around the outer circumference of 2.

The winding core of the present invention is a winding core in which a roll paper 4 is wound around the outer periphery of the core 2 by rotating a shaft 3 inserted in a core 2 having a hollow 1. It is characterized in that the non-adhesive portion of the locking sheet 5 adhered with one end wound around the outer periphery of the core 2 is released as a tongue piece 6.

Further, the width of the locking sheet 5 is set to the core 2
The length of the locking sheet 5 may be formed to be substantially the same as or substantially shorter than that of the above, and to be formed to have a length or a short length corresponding to one round of the outer circumference of the core 2.

[0013]

In the above structure, the core 2 is in a state in which the non-adhesive portion of the locking sheet 5 adhered with one end wrapped around the outer periphery is separated from the core 2 as the tongue piece 6.

When the roll paper 4 is wound around the core 2, the roll paper 4 is placed between the core 2 and the tongue piece 6 which is the non-adhesive portion of the locking paper 5 adhered to the outer periphery of the core 2. When the core 2 is rotated by the shaft 3 with the tip sandwiched, the tip of the roll paper 4 is sandwiched between the tongue piece 6 and the outer periphery of the core 2 at least when the roll paper 4 makes one revolution.
Further, as the core 2 rotates, the roll paper 4 is firmly held by the holding force between the tongue piece 6 and the core 2, and the subsequent winding can be performed without slipping.

In addition, after use, after the winding is completed, the hollow 1 of the core 2 is inserted into the shaft 3 for mounting roll paper of various devices.

Even when the roll paper 4 after winding is used, the winding end of the roll paper 4 maintains the state of being sandwiched between the tongue piece 6 and the outer periphery of the core 2 for the same reason as above. When the roll paper 4 is used up to the winding end without spinning around the roll 2, the tongue piece 6 is released from the state of being clamped to the end of the roll paper 4, and the end of the roll paper 4 is moved to the core 2 You are free to leave.

Embodiments of the present invention will be described below with reference to the drawings.

1A to 1C are perspective views showing various embodiments of the winding core according to the present invention. 2 (a) to 2 (c) are plan views corresponding to FIGS. 1 (a) to 1 (c), respectively. 3 (a) to 3 (c) are schematic views of a method of winding a core of roll paper according to the present invention.

Each of the cores 2 shown in FIGS. 1 and 2 has a structure in which the non-adhesive portion of the locking paper 5 adhered by winding one end around the outer periphery of the core 2 is detached as a tongue piece 6. Is. In these figures, 5a indicates an adhesive portion of the locking paper 5 to the outer periphery of the core 2, and 5b indicates an adhesive portion 5.
It is a boundary line between a and the tongue piece 6. It suffices that the adhesive portion 5a of the locking paper 5 with respect to the outer circumference of the core 2 is formed so as to go around the outer circumference of the core 2 about once.

The locking paper 5 is not particularly limited to the type of paper to be used, but a paper having a friction coefficient as large as possible improves the holding force at the time of winding.

The width of the locking sheet 5 is not particularly limited as long as it has a certain length. As an example,
Also, FIG. 2 shows three types.

1A and 2A, the width of the locking sheet 5 is substantially the same as the width of the core 2, and the tongue piece 6 released from the core 2 is long. And both ends of the tongue have a shape with corners cut off.

1B and 2B, the width of the locking sheet 5 is substantially the same as the width of the core 2 as described above, but the length of the tongue piece 6 is the same. Is shortened.

1 (c) and 2 (c), the width of the locking sheet 5 is significantly smaller than the width of the core 2, and the width of the tongue piece 6 is also the same. It is narrow.

As described above, the width or length of the locking paper 5, that is, the tongue piece 6, can be freely formed as long as the end portion of the roll paper 4 can be sandwiched between the cores 2. However, the length of the tongue piece 6 is such that it goes around the core 2 for convenience, and the holding force when the roll paper 4 is clamped also works effectively.

In FIGS. 3A to 3C, the core 2 described above is used.
In order to wind the roll paper 4 by using the core 2, the core 2 is inserted into a predetermined shaft 3 so that the rotation of the shaft 3 allows the core 2 to be driven and the roll side of the roll paper 4 is wound. The core 7 of the core 2 is inserted into the shaft 8 and the shaft 3 of the core 2 is connected to the rotary drive system.
Is in a free state or can be rotated for feeding.

Then, the core 2 is rotated (see FIG. 3 (b)) with the tip of the roll paper 4 sandwiched between the tongue piece 6 and the core 2 (see FIG. 3 (a)), and the roll paper 4 is rotated. Wrap one or more rounds.

By doing so, the tip of the roll paper 4 is clamped between the tongue piece 6 and the outer periphery of the core 2, and the core 2
By rotating, the roll paper 4 sandwiched between the tongue piece 6 and the core 2 is firmly locked on the outer periphery of the core 2, and subsequent winding can be performed without slipping on the outer periphery of the core 2.

When the winding is completed and the core is used, the hollow 1 of the core 2 can be inserted into the roll paper mounting shaft of various devices. Even in this use, since the winding tip of the roll paper 4 holds the state of being sandwiched between the tongue piece 6 and the outer circumference of the core 2, it can be used without spinning around the core 2.

When the roll paper 4 is used up to the winding end portion, the tongue piece 6 is released from the core 2 again, and the state in which the roll paper 4 is clamped with respect to the winding end portion is released.
The end portion of is freely separated from the core 2 and is used for detection of paper shortage and the like.

The method and wrapping core of the present invention are used not only for rolling rolls of tack paper used for handy terminals and the like, but also for wrapping strip-shaped paper around rolls of wrapping core such as cash register paper and toilet paper. Is applicable to everything.

[0032]

As described above, according to the present invention,
The roll paper is wound between the tongue piece and the core in the locked state, and the roll paper is wound. Therefore, it is possible to roll the shaft by the axial rotation method without using an adhesive, It can be rolled regardless of the type of paper such as easy tack paper.

Further, since the rolled paper wound according to the present invention is not fixed at the winding end by gluing or the like but is simply sandwiched, once it is released from the sandwiched state of the tongue, it is natural. In addition, the roll paper can be used up to the final end after being detached from the core, and it can be effectively used for detection of paper shortage.
