Description

The present invention relates to a coating film transfer tool used for transferring a transfer tape having a base film tape provided with a correction coating film, an adhesive for adhesion, a decorative coating film, and the like to a transfer target.

In the conventional coating film transfer tool, as shown in FIG. 5, the supply reel that feeds the transfer tape when the transfer tape runs and the take-up reel that winds the substrate tape after transfer are interlocked. In general, a coating film transfer tool Z (Patent Document 1) having an interlocking mechanism for meshing a take-up reel and a take-out gear arranged coaxially with the take-up gear is generally used.

In the conventional coating film transfer tool Z, as shown in FIG. 6, the supply reel and the take-up reel may be inclined due to the tension of the transfer tape. When the take-up reel is tilted with respect to the feeding reel, the transfer tape is skewed in the coating film transfer tool.

By the way, in recent years, with the demand for miniaturization of the coating film transfer tool by the user, the transfer tape has been made thinner, and the base material used has also been subjected to a release treatment from a paper base material (40 μm) such as glassine paper. Transition to a thin film (6 to 12 μm) resin film is progressing. Since the transfer tape has been made thinner, the reels wound around the transfer tape have become smaller, and the entire coating film transfer tool has been downsized.

JP2003-54191A

However, since the transfer tape is made thinner, the amount of skew of the transfer tape in the coating film transfer tool becomes larger than that of the conventional coating film transfer tool, and the occurrence frequency of skew is also increased. When the amount of skew of the transfer tape in the coating film transfer tool increases, the transfer tape travels with the end of the transfer tape in strong contact with the tape guide of the transfer head and the inner wall of the coating film transfer tool. . As a result, the transfer tape end part is broken or the transfer tape end part is damaged. When such a transfer tape with a broken edge or a scratched coating film on the edge is used, the transferred coating has a streaked surface or a scratched edge. There is a problem of becoming.

The present invention pays attention to the disadvantages of the conventional example, and even when a transfer tape having a thin film is used, the transfer tape in the coating film transfer tool is compared with the conventional coating film transfer tool. It is an object of the present invention to provide a coating film transfer tool that can reduce problems caused by skew.

In the first invention, the transfer tape is fed out from a feeding core in which a transfer tape provided with a coating film is provided on a base tape, and the coating film is pressed against a transfer target with a transfer head to transfer the transfer tape. A coating film transfer tool that rotates the take-up core in conjunction with a pair of meshing gears and winds the base tape after coating film transfer onto the winding core,
One of the gears is provided integrally with the feeding core, and the other of the gears is provided on a winding gear having a shaft that transmits rotation to the winding core in a slidable manner, and is provided integrally with the feeding core. Means for preventing the outer peripheral portion of the gear from being sandwiched between the winding core and the winding gear, and preventing the distance between the winding core and the winding gear from sandwiching the gear from increasing; and The means for transmitting the rotation so that the winding gear can slip to the winding core is an elastic piece that presses the inner periphery of the winding core provided on the shaft. Is a coating film transfer tool characterized by

The second invention is the coating film transfer according to the first invention , characterized in that the means for preventing the distance between the winding core and the winding gear from increasing is an elastic piece provided on the shaft. It is a tool.

The third invention is provided with means for transmitting rotation the slip it can, in a second invention, characterized in that the means for preventing the distance between the winding core and the take-up gear spreads are provided separately It is a coating-film transfer tool of description.

The fourth invention is provided with means for transmitting rotation the slip can, in the third invention means for preventing the distance between the winding core and the take-up gear spread, characterized in that it is provided alternately It is a coating-film transfer tool of description.

According to the present invention, the outer peripheral portion of the gear of the feeding core is sandwiched between the winding gear and the winding core, and the clearance between the winding gear and the winding core is widened. Since the preventing means is provided, the outer peripheral portion of the feeding core gear does not move beyond the range restricted by the gap between the winding gear and the winding core. As a result, in the coating film transfer tool of the present invention, the take-up core attached to the take-up gear does not tilt beyond the range restricted by the gap with respect to the feeding core. Therefore, the coating film transfer tool of the present invention can reduce both the amount of skew of the transfer tape and the frequency of occurrence of skew of the transfer tape, as compared to the conventional coating film transfer tool.

Coating film transfer tool A of the first embodiment of the present invention Coating film transfer tool B of the second embodiment of the present invention Winding core portion of coating film transfer tool C of the third embodiment of the present invention Coating film transfer tool D of 4th Embodiment of this invention Conventional film transfer tool Z The figure which shows the state which the supply reel and the take-up reel incline with the conventional film transfer tool The figure which shows the state which used the gear with very thin thickness for the conventional coating film transfer tool

A coating film transfer tool A according to the first embodiment of the present invention is shown in FIG. Fig.1 (a) is a top view of the state which opened the cover 2 of the coating-film transfer tool A of 1st Embodiment. FIG.1 (b) is MM sectional drawing of Fig.1 (a).

The coating film transfer tool A includes a case 1, a cover 2, a feeding core 3 wound with a transfer tape 9 coated with a coating film, a transfer head 6 that transfers the coating film to a transfer target, and a substrate after the coating film is transferred. The winding core 5 that winds the material tape 10 and the winding gear 4 that transmits the rotation of the feeding core 3 to the winding core 5 are configured. When the coating film transfer tool A is moved on the surface to be transferred while pressing the transfer head 6 against the surface to be transferred, the transfer tape 9 is fed out from the feeding core 3, and the transfer tape 9 is transferred by the pressure transfer unit 13 of the transfer head 6. Thus, the coating film is transferred to the transfer surface, and the remaining base tape 10 is wound around the winding core 5.

In the coating film transfer tool A, the gear 7 provided on the feeding core 3 and the gear 8 provided on the winding gear 4 are engaged with each other. Therefore, when the feeding core 3 rotates, the winding gear is interlocked with this. 4 rotates.

When the winding core 5 is mounted on the shaft portion of the winding gear 4, the three pressing pieces 11 provided at 120 ° intervals on the shaft of the winding gear 4 are elastically deformed to press the inner periphery of the winding core 5. Therefore, when the winding gear 4 rotates, this rotation is transmitted to the winding core 5 via the three pressing pieces 11.

The outer peripheral portion of the gear 7 provided on the feeding core 3 is configured to be sandwiched between the flange portion 14 provided on the winding gear 4 and the winding core 5. Since the thickness of the gear 8 of the winding gear 4 is thicker than that of the gear 7 of the feeding core 3, the width of this gap is larger than the thickness of the gear 7 of the feeding core 3.

A stopper 12 is provided at the tip of the pressing piece 11. The retainer 12 is a means for preventing a gap between the flange portion 14 of the winding gear 4 and the winding core 5 sandwiching the outer peripheral portion of the gear 7 from expanding. Since there is the stopper 12, the gap that sandwiches the outer peripheral portion of the gear 7 does not widen. As described above, since the outer periphery of the gear 7 is sandwiched between the gaps between the two parts and the means for preventing the gap from expanding is provided, the outer peripheral portion of the gear 7 moves beyond the range restricted by the gap. There is nothing. Since the outer peripheral portion of the gear 7 does not move beyond the range restricted by the gap, in the coating film transfer tool A, the winding core 5 attached to the winding gear 4 is There is no inclination beyond the range regulated by the gap. Therefore, in the coating film transfer tool A, the inclination of the winding core 5 with respect to the feeding core 3 can be reduced as compared with the conventional coating film transfer tool. As a result, the coating film transfer tool A can reduce both the amount of skew of the transfer tape and the frequency of occurrence of skew of the transfer tape, as compared with the conventional film transfer tool.

The distance between the flange portion 14 of the winding gear 4 and the winding core 5 sandwiching the outer peripheral portion of the gear 7, that is, the difference between the width of the gap and the thickness of the gear 7 is preferably 0.05 mm or more and 0.2 mm or less. 0.1 mm or more and 0.15 mm or less is more preferable. When this difference is less than 0.05 mm, the gear 7 comes into contact with the winding gear and / or the winding core, and the feeding core 3 moves smoothly with respect to the winding gear 4 and the winding core 5. There is a risk of disappearing. On the other hand, if this difference exceeds 0.2 mm, the effect on the skew of the transfer tape is reduced.

The pitch circle diameter ratio between the gear 7 and the gear 8 is such that the transfer tape 9 fed from the feeding core 3 is not loosened even when the outer diameter of the feeding reel of the transfer tape 9 wound around the feeding core 3 is large. The length of the base tape 10 wound around the winding core 5 is set to be longer than the length 9.

Since the length of the wound base tape 10 is set to be longer than the transferred transfer tape 9, the transfer tape 9 is tensioned, but a certain level of tension is applied to the transfer tape 9. Then, slip occurs between the pressing piece 11 and the inner periphery of the winding core 5 to release the tension of the transfer tape 9, so that the transfer tape 9 is not broken.

In this embodiment, the pressing piece 11 that is an elastic piece provided on the winding gear 4 is used as a means for transmitting rotation from the winding gear 4 to the winding core 5. Any transmission means may be used as long as it slips and releases the tension of the transfer tape 9.

The coating film transfer tool B which is 2nd Embodiment of this invention is shown in FIG. FIG. 2A is a front view of the coating film transfer tool B with the cover opened. FIG. 2B is an NN cross-sectional view of FIG.

The coating film transfer tool B is the same as the coating film transfer tool A of the first embodiment, except that the winding piece 4 is provided with the pressing piece 11 and the stopper 12 separately. In the coating film transfer tool B, three retainers 12 are provided on the shaft of the winding gear 4 alternately with the three pressing pieces 11 at intervals of 120 °.

By providing the retaining member 12 and the pressing piece 11 separately, the retaining member 12 and the pressing piece 11 do not interact with each other as compared with the case where they are integrally provided, and there is no adverse effect on the function that each of them should perform. can do. For example, when the retainer 12 and the pressing piece 11 are provided integrally as in the coating film transfer tool A of the first embodiment, if the pressing piece 11 is greatly elastically deformed by contacting the inner periphery of the core, the further Since the position of the retainer 12 provided at the tip of the pressing piece 11 changes, the retaining effect of the winding core 5 may be insufficient. However, such an influence can be prevented by providing the pressing piece 11 and the stopper 12 separately.

A coating film transfer tool C according to a third embodiment of the present invention is shown in FIG. Fig.3 (a) is a front view of the winding core part of the coating-film transfer tool C of the state which opened the cover. FIG. 3B is a cross-sectional view taken along line OO in FIG.

The coating film transfer tool C is the same as the coating film transfer tool B of the second embodiment except that the shape of the pressing piece 11 provided on the winding gear 4 is different.

As shown in FIG. 3B, the pressing piece 11 of the winding gear 4 of the coating film transfer tool C has a U-shaped cross section. By making it U-shaped, the length of the pressing piece 11 of the coating film transfer tool C is longer than the pressing piece 11 of the coating film transfer tool B. In the coating film transfer tool C, the pressing piece 11 is made difficult to break by making the pressing piece 11 longer.

The coating film transfer tool D which is 4th Embodiment of this invention is shown in FIG. Fig.4 (a) is a front view of the coating-film transfer tool D of the state which opened the cover. FIG. 4B is a cross-sectional view taken along the line P-P in FIG.

The coating film transfer tool D, except that the gear 7 portion of the feeding core 3, the gear 8 portion of the winding gear 4 and the flange portion 14 are made of a material different from that of the other portions of the feeding core 3 and the winding gear 4. This is the same as the coating film transfer tool B of the second embodiment.

The feeding core 3 is manufactured by inserting a stainless steel gear 7 portion into an injection mold and molding a portion other than the gear 7 with a thermoplastic resin. Further, the winding gear 4 is manufactured by inserting the stainless steel gear 8 portion and the flange portion 14 into an injection mold and molding the portions other than the gear 8 and the flange portion 14 with a thermoplastic resin. By manufacturing the gear 7 and the gear 8 portion of a metal such as stainless steel, the gear 7 and the gear 8 can maintain the strength necessary for transmitting the rotation even if the gear 7 and the gear 8 are very thin. Therefore, the thickness of the coating film transfer tool D can be made very thin. In the present embodiment, only a part of the feeding core 3 and the winding gear 4 is made of metal, but the whole feeding core 3 and the winding gear 4 may be made of metal. Further, the metal is not limited to stainless steel, and any metal may be used as long as the strength as a gear can be secured.

If the gear 7 and the gear 8 are made very thin, in the conventional coating film transfer tool Z shown in FIG. 5, the tooth tips of the gears may shift up and down as shown in FIG. In the coating film transfer tool of the invention, the outer peripheral portion of the gear 7 is sandwiched between the winding gear 4 and the winding core 5 and is kept engaged with the gear 8, so that the gear 7 and the gear 8 do not mesh. There is no fear.

The coating film transfer tool D according to the fourth embodiment has a great effect when using a narrow transfer tape and manufacturing a coating film transfer tool in which the entire size of the coating film transfer tool is reduced. It is.

Even when a narrow transfer tape is used, if the interlocking mechanism of the conventional coating film transfer tool Z shown in FIG. That is, the overall width of the coating film transfer tool is only reduced in size by the reduction in the width of the transfer tape. Further, in the coating film transfer tool using a narrow transfer tape, it is necessary to reduce the skew feeding amount of the transfer tape as compared with the coating film transfer tool using a wide transfer tape. For example, in a coating film transfer tool using a transfer tape with a tape width of 6 mm, even if the transfer tape is skewed 1 mm, it is only 1/6 of the tape width, so the coating film at the end of the tape is scratched. Although there is a possibility that problems such as sticking may occur, there is no problem that the transfer tape cannot run. On the other hand, in a coating film transfer tool using a transfer tape having a tape width of 2 mm, if the transfer tape is skewed by 1 mm, the tape is also skewed by half, so that the transfer tape may be twisted or cut. There is a risk that the transfer tape cannot run.

Thus, in a coating film transfer tool using a transfer tape with a narrow tape width, the skew feeding amount of the transfer tape needs to be smaller than that using a transfer tape with a wide tape width. The effect of adopting the configuration of the coating film transfer tool is great. In addition, when the configuration of the coating film transfer tool of the fourth embodiment is adopted for a coating film transfer tool that uses a transfer tape with a narrow tape width, the width of the interlocking mechanism portion is reduced in addition to the tape width being narrowed. As a result, the entire width of the coating film transfer tool can be reduced.
