Description

  The present invention belongs to the technical field of a coating film transfer tool for press-transferring a character correction coating film, an adhesive film, a decorative coating film, etc. to a transfer surface. It belongs to the technical field of a horizontal transfer type coating film transfer tool guided almost parallel to the front and back surfaces.

FIG. 9 is a top view of a state in which a cover of a conventional horizontal drawing type film transfer tool is removed (see, for example, Patent Documents 1 to 4).
The coating film transfer tool 10A includes a case 111 in which a feeding core 115 around which a transfer tape 119 is wound and a winding core 116 around which the transfer tape 119 after coating film transfer is wound are rotatably housed. A point-shaped transfer head 118 protrudes from the end 111, one end of the transfer tape 119 is extended from the supply core 115, and twisted by 90 ° before the transfer head 118, and passes through the pressure transfer portion 132 of the transfer head 118. Then, the torsion is returned to the original state, or is further twisted by 90 °, and wound around the winding core 116.

  According to this horizontal pulling type coating film transfer tool 10A, the transfer tape 119 is twisted by 90 ° in front of the transfer head 118, so that the transfer tape 119 is substantially parallel to both the front and back surfaces of the case 111 in the transfer head 118. Guided. For this reason, it is possible to erase erroneously written characters by gripping both sides by hand and moving them horizontally while pressing them on a desk without stretching their elbows, so that the transfer head 118 can be accurately and stably placed at a desired location. There is a feature that can be moved to.

  However, the coating film transfer tool 10A has a structure in which the surface of the transfer tape 119 is changed by 90 ° by abutting against the guide pins 122 and 123 at two locations of the entrance and exit of the transfer head 118. It has been a heavy load on the tape 119, making it difficult for the transfer tape 119 to be smoothly fed out. That is, in this coating film transfer tool 10A, the urging force required to feed out the transfer tape 119 depends on the frictional force between the coating film at the tip of the transfer head 118 and the surface to be transferred. Adhesives such as tapes are weakly sticky and therefore have a low frictional force, making it difficult to feed out the transfer tape 119 as compared with strong adhesives.

On the other hand, Patent Document 5 discloses a coating film transfer tool 10B as shown in FIG.
In the coating film transfer tool 10B, the feeding core 3 and the winding core 4 are rotatably accommodated in the case 2, and the first bevel gear 7 is rotatable in the case 2 so that the rotation axis thereof is coaxial with the feeding core 3. The transfer head 5 having the pressure transfer portion 6 protrudes from the end portion of the case 2 and is engaged with a second bevel gear 9 formed on one side of the winding core 4 so as to cross the rotation axis. The transfer tape T is fed from the feed core 3 and twisted by 90 ° in front of the transfer head 5, and is divided into a coating film transferred to the transfer surface in the pressure transfer unit 6 and the remaining tape base T1, and the tape base The material T1 is wound around the winding core 4 without being twisted.

According to this coating film transfer tool 10B, since the transfer tape T is guided substantially parallel to both the front and back surfaces of the case 2 in the transfer head 5, the pressure transfer of the transfer head 5 with the user lying on the case 2 is performed. The coating film can be transferred while visually recognizing the portion 6 from above, and after the coating film transfer, the tape base material T1 is wound around the winding core 4 without being twisted. However, it is said that the transfer tape T can be smoothly fed even if the adhesive force is weak such as a correction tape or a marking tape and the frictional force is small.

  However, in the coating film transfer tool 10B, the first bevel gear 7 and the feeding core 3 are both coaxial, and the second bevel gear 9 is formed on one side of the winding core 4, so that the feeding core 3 The positional relationship between the winding core 4 and the winding core 4 is limited to the same position as a bevel gear in which the respective axes are orthogonal to each other, and the degree of freedom in designing both cores is poor.

  Further, the coating film transfer tool increases the number of rotations of the winding core more than the rotation number of the feeding core so that the transfer tape in use does not loosen. 4, the gear ratio between the first and second bevel gears 7 and 9 coaxial with each other needs to be increased.

  Specifically, the gear ratio can be increased by increasing the number of teeth of the first bevel gear 7 or decreasing the number of teeth of the second bevel gear 9. Since there is a minimum number of teeth necessary to function as a gear and there is a limit to reducing the number of teeth, the number of teeth of the first bevel gear 7 is eventually increased.

  However, if the number of teeth is increased without changing the gear module, the outer diameter of the gear increases and the coating film transfer tool cannot be made compact. Also, if the gear module is made smaller without changing the outer diameter of the gear and the number of teeth is increased, advanced manufacturing technology is required to resin-mold the gear with the smaller module, resulting in higher manufacturing costs and replacement. In the case of the type, there is a problem that the meshing margin between the tooth tip of the first bevel gear 7 on the main body side and the tooth base of the second bevel gear 9 is reduced, and the bevel gears 7 and 9 are not smoothly meshed with each other.

  In the present invention, a feeding core, a winding core, and a first bevel gear are rotatably housed in a case, a transfer head having a pressing transfer portion protrudes from the case end, and a transfer tape extends from the feeding core. The winding core is divided into a coating film and the remaining tape base material that is fed out, twisted before the transfer head, and transferred to the transfer surface in the pressure transfer portion, and the tape base material is not twisted. In the coating film transfer tool adapted to be wound around the winding core, the feeding core and the first bevel gear are rotated together by an interlocking mechanism, and a second bevel gear provided on one side of the winding core is The above-mentioned problem has been solved by a coating film transfer tool characterized in that the first bevel gear and the rotation axis intersect and mesh with each other.

According to the present invention, the feeding core and the first bevel gear are rotated together by the interlock mechanism, and the second bevel gear provided on one side of the winding core is the first bevel gear and the rotation shaft. By crossing and meshing with each other, the feeding core and the winding core can be designed relatively freely without limiting the positions.
Further, since the speed can be increased in two steps from the feeding side to the winding side, and the speed increasing ratio in each step can be reduced, the outer diameter of the first and second bevel gears can be reduced and the module can be increased. it can. And even if it is an exchange type, the meshing margin of both gears will become large, and since winding force will be transmitted reliably, rotation will become smooth.

Fig. 5 (a) is a perspective view of the coating film transfer tool replacement cassette of the present invention as seen from above, and Fig. 5 (b) is the main body of the coating film transfer tool of the present invention from above. 6 is an exploded sectional view taken along line 2-2 in FIG. 1, FIG. 7 is an exploded sectional view taken along line 3-3 in FIG. 1, and FIG. 8 is an exploded sectional view taken along line 4-4 in FIG. The coating film transfer tool 10 of the present invention is a transfer in which the feeding core 20, the winding core 30, and the first bevel gear 40 are rotatably accommodated in a case 60, and a pressing transfer portion 52 is provided from the end of the case 60. The head 50 protrudes, the transfer tape T is fed out from the feeding core 20, and the direction of the transfer tape T is guided by being twisted by 90 ° by the guide pin G 1 in front of the transfer head 50. The coating film to be transferred and the remaining tape base material T1 are divided, and the tape base material T1 is guided by the guide pins G2 without being twisted and wound around the winding core 30.
The twist of the transfer tape T is not limited to 90 °, and the transfer tape T may be twisted about 45 ° to 80 ° and wound around the winding core 30 without being twisted after transfer. .

  The case 60 includes a main body 62 and an exchange cassette 64. The first bevel gear 40 is attached to the main body 62, and the feeding core 20, the winding core 30, and the transfer head 50 are attached to the replacement cassette 64.

The main body 62 includes support shafts S1 and S2, and the support pulley S1 and the first bevel gear 40 are rotatably fitted to the support shaft S1 and S2, respectively. An endless rubber belt B (O-ring) is wound around the feeding pulley 22 and the first bevel teeth 40 so that the feeding pulley 22 and the first bevel teeth 40 rotate in conjunction with each other. The feeding core 20 is mounted on the same axis. By this belt-type interlocking mechanism, the feeding core 20 and the first bevel gear 40 rotate in conjunction with each other. Of course, gears may be provided in the feeding pulley 22 and the first bevel gear 40 in place of the belt type, and the two gears may be linked via an intermediate gear.
On the other hand, the winding core 30 is rotatably fitted to the exchange cassette 64, and the second bevel gear 32 formed on one side of the winding core 30 intersects the first bevel gear 40 and the rotation axis. Mesh.

  When the transfer tape T is fed from the feeding core 20, the rotation of the feeding core 20 is transmitted to the first bevel teeth 40 via the feeding pulley 22 and the rubber belt B, and the rotation of the first bevel teeth 40 is the second. It is transmitted to the winding core 30 via the tooth 32. Thus, the feeding core 20 and the winding core 30 rotate in conjunction with each other.

  In the coating film transfer tool 10 of the present invention, after the coating film is transferred, the tape substrate T1 is wound around the winding core 30 without being twisted. Further, in this way, the feeding core 20 and the first bevel gear 40 are interlocked and rotated by the belt-type interlocking mechanism, and the second bevel gear 32 formed on one side of the winding core 30 is the first bevel gear 40. And the rotating shaft can be crossed and meshed so that the speed can be increased in two stages from the feeding side to the winding side, and the speed increasing ratio in each stage can be reduced. Therefore, the first and second bevel gears The outer diameter of 40 and 32 can be reduced, and the module can be enlarged. Moreover, even if it is an exchange type, the meshing margin of both gears will become large, and since winding force will be transmitted reliably, rotation will become smooth. Furthermore, it is possible to design relatively freely without limiting the positions of the feeding core 20 and the winding core 30.

  In addition, in this way, by conducting power transmission by the rubber belt B that is wound between the feeding pulley 22 and the pulley of the first bevel gear 40, the feeding side and the winding side are synchronized with each other between the pulley and the belt. Therefore, a separate slip mechanism is not required.

The ring portion R of the main body 62 can be detached from the main body 62. By removing the ring portion R from the main body 62, the replacement cassette 64 can be removed from the main body 62 or the replacement cassette 64 can be attached to the main body 62. it can. The ring portion R is provided with a coupling means (not shown) such as a projection for coupling with the main body 62, but a projection for fitting with the replacement cassette 64 may be further provided.
In addition, in the winding core 30 and the first bevel gear 40, the main body 62 and the replacement cassette 64 are fixed by providing a hook (not shown) in the replacement cassette 64, and a hole (see FIG. This can be realized by providing (not shown).
It should be noted that various means can be selected as the means for coupling the ring portion R to the main body 62 and the means for fixing the main body 62 and the exchange cassette 64, and the above means are merely examples.

  Thus, by dividing the coating film transfer tool 10 into the main body 62 and the replacement cassette 64, when the transfer tape T of the coating film transfer tool 10 is used to the end, the main body 62 can be reused, and only the replacement cassette 64 is used. Since it is only necessary to replace it, the amount of plastic to be discarded can be reduced.

On the other hand, it is necessary to lengthen the transfer tape T in order to increase the commercial value, and since the outer diameter of the tape base T1 wound around the winding core 30 after transfer increases, The replacement cassette 62 has a large protruding shape.
The outer diameter of the tape is determined by the tape thickness and the tape length. An extremely short tape has no commercial value, so a length of 8 to 10 meters is required. For example, when the tape length is 8 meters, the tape thickness is 22 micrometers, and the winding core diameter is 6 millimeters, the outer diameter is 17 millimeters. In addition, since it will become difficult to have if the width dimension of a coating-film transfer tool is too large, even if it is the part of the winding core 30, it is preferable that it is 20 millimeters or less. Since the thickness of the tape base material T1 is as large as 32 micrometers in glassine paper, the outer diameter of the tape base material T1 is increased. In the coating film transfer tool 10 of the present invention, in order to reduce the width dimension to 20 mm or less, a plastic tape base material having a thin tape thickness and strong, for example, polyethylene terephthalate having a tape thickness of 4 to 22 micrometers. The tape base material is preferable.

  In addition, although the cassette exchange type coating film transfer tool has been described so far, the present invention is not limited to this, and can be applied to a coating film transfer tool in which a conventional cassette and a main body are integrated. Of course.

As described above, according to the present invention, the feeding core and the first bevel gear are rotated together by the interlock mechanism, and the second bevel gear provided on one side of the winding core is the first bevel gear. By configuring the bevel gear and the rotation shaft to intersect and mesh with each other, the feeding core and the winding core can be designed relatively freely without limiting the positions.
Further, since the speed can be increased in two steps from the feeding side to the winding side, and the speed increasing ratio in each step can be reduced, the outer diameter of the first and second bevel gears can be reduced and the module can be enlarged. it can. And even if it is an exchange type, there exists an effect that the meshing margin of both gears becomes large, and since winding force is transmitted reliably, rotation becomes smooth.
