Description

In a broad sense, the present invention relates to a limited length transfer device and an infinite length transfer device for a coating film.

A coating film transfer tool for transferring a coating film from a base of a tape to a target substrate by a roller while feeding a tape coated with a coating film on one side and wound in a roll is widely provided.
For example, if the coating film is an adhesive material, it is used for application to a cover of an envelope or the like, and if the coating film is an opaque film containing a pigment, it is used for correction for covering characters and the like.

The present application improves upon these conventional embodiments to expand the degree of freedom of the posture of the apparatus at the start of transfer and improve the accuracy of the transfer start position.

As shown in the background art, in the coating film transfer tool for transferring the coating film to the adherend surface as the target substrate by pressing with a roller from the base surface side of the tape,
By providing a member that can rotate and support the roller in a rotatable manner, the roller can be moved slightly along the surface on the base side of the tape so that the roller always contacts the base surface with the coating film. Constitute.

In addition, the elastic material is urged over the entire moving range of the roller, and the elastic material has viscosity at the same time, so that the coating film can be easily cut at the end position of the transfer.

In the conventional example, it was necessary to adjust the angle by intuition so that the apparatus was laid down and the coating film was in contact with the adherend surface, but in the present invention, the range of adjustment was widened and the roller was applied straight from above. By touching the surface, the transfer start position can be accurately positioned, and the tape can be pulled out.

Further, after the use is completed, the above-mentioned intuition and extra operation are not required because the roller is moved to a portion where the coating film is provided by elasticity.

First, the configuration of the conventional example will be described in detail.

1 to 3 show an example of a conventional coating film transfer tool.
As shown in FIG. 1, a tape arc 11c comprising a tape portion 11a with a coating film and a base portion 11b of a tape without a coating film is provided outside a container 3 constituted by a base 1 and a cover 2 held by the user's hand. And a roller 4 disposed so that the tape arc 11c does not sag inside.

The left figure of FIG. 2 is a YY sectional view of FIG. 1, and the right figure is a XX sectional view.
The configuration and operation will be described with reference to FIG.
The tape 11 is wound around the delivery reel 7 to form a roll. Further, the delivery gear 9 is arranged coaxially with the delivery reel 7, and a friction spring 7 b acts between the delivery reel 7 and the delivery gear 9, and the delivery reel 7 and the delivery gear 9 are integrated with the delivery reel of the base 1. The shaft 11e is used as a guide and rotates around the point P1.
A reverse rotation preventing claw 1 d that restricts the rotation direction only to the delivery direction acts on the delivery gear 9.
A take-up reel 8 and a take-up gear 10 that rotate around a point P2 with the take-up reel shaft 1f as a guide are disposed on the upper portion of the base 1, and both rotate together.
A roller 4 that rotates around a point P3 with a roller shaft 1a disposed at the lower part of the base 1 as a guide is fitted.

The end of the tape 11 is separated from the outermost periphery of the roll wound around the delivery reel 7, and the roller 4 is rotated in the clockwise direction so as to come into contact with the outermost periphery of the roll again on the opposite side and wind in the counterclockwise direction. To be held in.
A tape arc 11c is formed by a tape portion 11a with a coating film and a base portion 11b of a tape without a coating film, and the tape arc 11c is maintained in tension without being loosened by a roller 4 disposed inside thereof.
Further, since the number of teeth of the take-up gear 10 is sufficiently smaller than that of the delivery gear, the rotational peripheral speed of the take-up reel becomes faster than that of the outermost roll of the tape 11. At the same time, the difference in peripheral speed is slipped and released by the friction spring 7 b, so that the tape 11 is wound around the take-up reel 8 without sagging in the container 3.
A part of the tape arc 11 c and the roller 4 are exposed to the outside of the container 3.

The usage method will be described with reference to FIG.
The user holds the container 3 by hand, presses the roller 4 against the adherend surface 12, and pulls it in the direction of the arrow V. The tape portion 11a with the coating film is placed in the direction of the arrow S while being in contact with the adherend surface 12 at the point PD. At point PD, the coating film is transferred to the adherend surface 12. Therefore, after the roller 4 is rotated, the base portion 11b of the tape without the coating film is wound around the take-up reel as described above.
When the container 3 is lifted so as to be swung forward, the coating film is broken at the point PD, and the tape portion 11a with the coating film can be pulled out by pressing the roller 4 against the adherend surface again from the next time.

By the way, the above conventional example has a large drawback in use.
This will be described with reference to FIGS.

In FIG. 3, in order to pull the container 3 forward, the container 3 is usually pulled and moved in the direction of the arrow V while the container is laid down. That is, when the angle W1 formed between the container 3 and the adherend surface is smaller than 90 degrees, as described above, the coating film can be removed at the point PD.
In the case of re-use, if it is intended to transfer to a small area such as a large stamp, it is desirable to accurately determine the initial position of the transfer, so if the container is set up straight and pressed from directly above, the state shown in FIG. Thus, even if it touches the surface to be adhered at the point PT and lays it forward, there is no coating between the point PT and the point PD, so that the positioning at the beginning of the transfer cannot be performed accurately. In this case, as shown in FIG. 5, a deviation DF occurs between the desired initial transfer position and the actually transferred coating film 13.

In general, PET having a low coefficient of friction is used as the tape base material, and even if the base portion 11b of the tape without a coating film is applied to the adherend surface 12 at the point PT, slipping occurs between them. There are many cases where the tape cannot be fed and transfer cannot be performed only by the occurrence of the error.

As shown in FIG. 6, if the angle W2 formed by the container 3 and the adherend surface is smaller than W1 in FIG. 3, that is, if the container 3 is further laid and placed on the adherend surface 12, the point PD becomes the adherend surface 12. 5 does not occur, but the laying out of the container 3 makes it very difficult to position the transfer at the beginning.

As described above, since accurate transfer is very difficult at present, it is practically impossible to use, for example, a small area of a stamp size. But only when it's okay.

If the tape arc 11c is fed by the aforementioned deviation DF before use, the initial position of the transfer can be accurately determined with the container 3 standing straight, but a complicated feeding mechanism is required, and the apparatus This leads to an increase in size and failure, which is not desirable.

The present invention eliminates the above-mentioned drawbacks with a very simple configuration without providing a complicated mechanism, and improves the user's pulling comfort.

A swing arm 5 that rotatably supports the roller 4 is provided, and is supported by the base 1 so that the swing arm can be fanned at a limited angle. The swing arm 5 is in contact with an elastic material to urge the roller to a clockwise position.

One of the embodiments will be described with reference to FIGS.
As shown in FIG. 7, the rotating parts centered on the points P1 and P2 are the same as in the conventional example.
Therefore, the reference numerals in the figure are omitted and the description is also omitted.
The swing shaft portion 1b is provided on the base 1, the swing center hole portion 5b of the swing arm 5 is fitted, and the swing arm 5 can be fanned around the point P0. The roller 4 is fitted to the roller shaft portion 5a formed integrally with the swing arm 5, and the roller 4 rotates around the point P3. Further, an elastic material action portion 5 c is formed integrally with the other end of the swing arm 5 and is in contact with the elastic material 6 implanted in the elastic material guide portion 1 g of the base 1. As shown in FIG. 8, the guide protrusion 5 d formed on the back surface integrally with the swing arm 5 is fitted into the guide hole 1 c formed in the base 1 to regulate the fan angle of the swing arm 5.

As shown in FIG. 9, at the beginning of use, when the swing arm 5 stands straight and is pressed against the adherend surface 12 and pulled in the direction of the arrow V, the swing arm 5 is centered on the point P0 as shown in FIG. As described above, the elastic material is compressed simultaneously to the position of one end of the restricted angle as described above, and at the same time, the elastic material 6a is compressed.

In FIG. 11, the swing arm 5 fanned to the position determined in the clockwise direction is a two-dot chain thin line, and the swing arm 5 fanned back to the position determined in the counterclockwise direction by the elastic material 8 is a solid line. , The middle line.

As shown in FIGS. 10 and 11, when the fan is moved clockwise, it is in contact with the adherend surface at the point PA in FIG. 11, and in this state, it is swung forward as in the conventional example. When lifted in this way, the coating film can be point PA.
Thereafter, the elastic member 8 acts, and the swing arm 5 is fanned to a predetermined angular position in the counterclockwise direction. At the same time, the point PA on the arc 11c of the tape wraps around the roller 4 and moves to the position of the point PB. .
Therefore, after use, the roller 4 is always sufficiently covered with the tape portion 11a with the coating film, and the tape portion 11a with the coating film can be attached to the adherend surface 12 even if the angle W is reduced and not laid down for the next use. Can be transferred to the coating film.
The peripheral lengths 3 and 2.1 on the roll outer diameter of the tape 11 in FIG. 11 are the movement amounts.
In addition, since a roll outer diameter changes according to use, a movement amount also changes simultaneously.
The dimension of 28 ° indicates the fan angle movement range.

According to this embodiment, in use, even if the swing arm 5 is pressed straight against the adherend surface, the coated tape portion 11a always comes into contact with the adherend surface, and positioning at the beginning of transfer is easy. it can.

FIG. 12 shows three states of the swing arm fan movement.
The left figure shows the restricted position in the counterclockwise direction, the central figure shows the central position of the fan angle range, and the right figure shows the restricted position in the clockwise direction.
The tape arc 11c extends from the point P4 to the point P5. Since the fan center P0 of the swing arm 5 is in the vicinity of the line connecting the points P1 and P3, the length of the tape arc 11c is set to the above three lengths. Almost no change in the state. Therefore, the arc 11c of the tape does not loosen while maintaining the tension.

In addition, as the elastic material, if the continuous foamed polyester with little repulsion and no compression strain is used, the swing arm 5 is not restored immediately even if the force to press the container 3 against the adherend surface 12 is lost. It is easy to cut the coating film at the point PA in FIG.

In addition, the force of the above-mentioned continuous foamed polyester increases nonlinearly against strain. Therefore, in use, the swing arm 5 in the state returning to the counterclockwise direction starts to rotate clockwise even if the pressing force is weak. However, since the coating surface has adhesiveness with respect to the adherend surface, the tape can be pulled out without the contact point slipping.

In addition, the force of pressing the container 3 is less affected by the property of the above-mentioned continuous foamed polyester having less resilience and viscosity. Therefore, with elasticity alone, it is less likely that the user's hands will be concerned about the difficulty of use, that is, the increase or decrease of the repulsive force.
