The present invention relates to a coating film transfer tool in which a transfer head can protrude or retract into the inside of a casing body.

In the past, there has been provided a coating film transfer tool in which a transfer head can protrude or retract into the inside of the case body. For example, the coating film transfer device disclosed in Japanese Patent Application Laid-Open No. 2007-136959 disclosed in the Japanese Patent Application Publication No. 2007-136959 is a mechanism capable of protruding or retracting the transfer head by a slider mechanism. In such a coating film transfer tool, when the transfer head is brought into a retracted state from the protruding state, the gear is rotated by a rack provided on the slider, and the slider is moved forward and backward along with the transfer head. mobile. When the gear can move freely in the front-rear direction, so that the transfer head changes from a protruding state to a retracted state, it meshes with the gear that drives the supply bobbin, reverses the supply bobbin, and takes up the amount of the transferred transfer head. The amount of transfer belt. At this time, the gear for driving the take-up bobbin rotatably connected to the supply bobbin is idling. When the transfer head is changed from the retracted state to the projected state, the freely movable gear is moved forward, and the meshing with the gear driving the supply tube is released. The take-up bobbin is provided with a reverse prevention mechanism. Accordingly, the transfer belt is stretched by the advance of the transfer head, and the supply tube is rotated.

However, the take-up amount of the transfer head when it is retracted may vary depending on the remaining amount of the unused transfer belt wound onto the supply bobbin. Therefore, the position of the separation line of the unused portion of the transfer belt with respect to the transfer roller of the transfer head varies with the remaining amount of the unused transfer belt. Therefore, when it is used again, it may be necessary to manually adjust the position of the separation line of the unused part of the transfer belt, etc., which may cause tedious procedures during use.

The present invention has been made in view of the foregoing problems, and an object thereof is to provide a coating film transfer device capable of positioning a separation line of an unused portion of a transfer belt on a transfer head with better accuracy.

At this time, the press-fit rib 32c2 formed on the outer periphery of the cylindrical shaft portion 32c is crimped by the inner peripheral surface of the large-diameter portion 37a1. The rotational force when the first supply bobbin drive shaft 37 and the second supply bobbin drive shaft 32 rotate relative to each other, that is, the clutch force of the clutch mechanism 4, is that the large-diameter portion 37a1 is crimped by the press-fit rib 32c2. The force on the inner peripheral surface is determined, that is, the gripping force is determined by the length of the press-fit rib 32c2 and the large-diameter portion 37a1 at the time of pressure contact. In addition, the annular concave-convex portion 32d at the front end portion of the cylindrical shaft portion 32c is elastic due to its concave-convex shape. Therefore, when the annular uneven portion 32d abuts on the step portion 37a3, the convex portion of the annular uneven portion 32d is compressed and deformed in the inner diameter direction. Accordingly, the amount of insertion when the cylindrical shaft portion 32c is inserted into the large-diameter portion 37a1 can be adjusted. Thereby, the insertion amount of the press-fit rib 32c2 (that is, the length of the press-fit rib 32c2 and the large-diameter portion 37a1 being press-bonded) can be adjusted, and thus the gripping force can be adjusted. Therefore, the holding force of the clutch mechanism 4 can be set to a fixed value without manufacturing errors of the components.

When the protruding operation is performed, although the transfer belt T is tensioned by the transfer roller 21a of the transfer head 21, the reverse rotation of the take-up bobbin drive shaft 35 is prevented by the reverse prevention mechanism 6, so only The supply bobbin 82 is rotated in the transfer direction of the transfer belt T, and the transfer belt T is delivered.

In addition, when the protrusion retracting operation portion 7 moves forward at a very fast speed, the stepped portion at the front end of the guide groove 52j abuts on the buffer lever 71c, causing the buffer lever 71c to rebound, so the protrusion can be retracted during operation. When the operation portion 7 is inserted, a good operation feeling is obtained.

The coating film transfer tool 10 is used by protruding the transfer head 21 as described above. At this time, by the engagement between the step surfaces 22b3, 22c3 and the front end faces 52h1c, 52h2c of the upper component guide 52h1 and the lower component guide 52h2, it can withstand the pressing from the transfer head 21 during use. pressure. In addition, the transfer operation of the transfer belt T is performed by using the coating film transfer tool 10, the unused transfer belt T is delivered from the supply bobbin 82, and the coating film is transferred by the transfer roller 21a. It is printed on a paper surface and the like, and the used tape body is taken up by a take-up bobbin 83. At this time, the number of teeth of each gear of the rotary coupling mechanism 30 (supply bobbin transmission gear 36, transmission gear 34, and winding bobbin transmission gear portion 35b) is set, so that the winding amount of the winding bobbin 83 is always larger than The delivery amount of the supply bobbin 82. The difference between the transmission amount and the winding amount is adjusted by driving the clutch mechanism 8. Therefore, an appropriate tension is often applied to the transfer belt T to reduce slack in the transfer belt T and the like.

When the use of the coating film transfer tool 10 is ended and the retracting operation is performed, when the protruding retracting operation portion 7 is retracted, the slider 71 is also retracted, and the pressing portions 71a and 71b press the inclined surfaces 22b1 and 22c1, As a result, the slider engaging portions 22b and 22c approach each other. In this way, the stepped surfaces 22b3, 22c3 and the upper end guides 52h1 and 52h2 of the lower end guide 52h2 are released from the engagement state, and the transfer head 21 is retracted as shown in FIG. 5b after passing through the state shown in FIG. 5a.

When the retracting operation is performed, the transfer belt T is the amount of the stroke after the winding of the transfer head 21 only. The take-up transfer belt T during the retracting operation will be described with reference to Figs. 6a and 6b.

FIG. 6 a shows the state of the coating film transfer tool 10 in use (that is, the protruding state of the transfer head 21). When the coating film transfer tool 10 is used to move the protruding retracting operation portion 7 to the rear, the rear movement of the transfer head group 20 is also started via the slider 71. In this way, the first abutting portion 22 a 1 of the slider body portion 22 a of the slider portion 22 abuts on the front edge surface of the abutting protruding portion 31 b of the intermediate gear 31. Since the contact range of the first contact portion 22a1 toward the front edge surface of the contact protrusion portion 31b lies below the rocking shafts 31c and 31d, the intermediate gear 31 is closer to the rack portion 31a toward the supply bobbin drive shaft gear portion. The direction of 32a (clockwise in FIGS. 6a and 6b) is rocked around the rocking shafts 31c and 31d. When the intermediate gear 31 is shaken, the rack portion 31 a and the supply bobbin drive shaft gear portion 32 a mesh with each other. When the protrusion retracting operation portion 7 is moved rearward, the rack portion 31a is also moved rearward, and the bobbin drive shaft gear portion 32a is rotated and supplied. When the supply bobbin drive shaft gear portion 32 a is rotated and the second supply bobbin drive shaft 32 is rotated, the first supply bobbin drive shaft 37 is also rotated via the clutch mechanism 4. When the first supply bobbin drive shaft 37 is rotated, the supply bobbin 82 is rotated to interlock with the backward movement of the transfer head 21, that is, interlocked with the backward movement of the transfer head group 20 to take up the amount that has retracted Transfer belt T. At this time, the reverse rotation of the take-up bobbin 83 is restricted by the reverse rotation prevention mechanism 6. At this time, since the driving clutch mechanism 8 is operated, the supply bobbin transmission gear 36 is not rotated, and the first supply bobbin drive shaft 37 and the supply bobbin transmission gear 36 are relatively rotated.

The operation of the intermediate gear 31 during the projection operation of the transfer head 21 is as follows. As shown in FIG. 7a, when the coating film transfer tool 10 in which the transfer head 21 has been retracted is used, the protrusion retracting operation portion 7 is moved forward. Thereafter, the transfer head group 20 also starts to move toward the direction via the slider 71. Thereafter, as shown in FIG. 7b, the second abutting portion 24c of the hook portion 24 (more specifically, the corner portion 24c1 of the second abutting portion 24c) is an abutting rear edge surface of the abutting protruding portion 31b. . The contact portion of the second contact portion 24c toward the rear edge surface of the contact protrusion 31b is located below the rocking shafts 31c and 31d. Therefore, the intermediate gear 31 faces the supply bobbin drive shaft gear portion 32a and the rack portion. The direction in which 31a is separated (counterclockwise in FIG. 7b) is rocked around the rocking shafts 31c and 31d. When the protrusion retracting operation portion 7 is continuously moved forward in the state of FIG. 7B, the meshing state of the supply bobbin drive shaft gear portion 32 a and the rack portion 31 a is released, so it is pulled by the transfer roller 21 a. The stretched transfer belt T is delivered from the supply bobbin 82.

In addition, at this time, since the protruding portion 31e of the intermediate gear 31 is abutted to the inclined portion 24b of the hook portion 24, the intermediate gear 31 is restricted from being separated from the supply barrel driving shaft gear portion 32a and the rack portion 31a. Shake in the direction. Therefore, since the rocking stroke of the intermediate gear 31 can be limited to a minimum distance, the responsiveness of the intermediate gear 31 can be optimized. In addition, since the supply bobbin drive shaft gear portion 32a and the rack portion 31a are formed by the teeth of the ratchet device, the supply bobbin drive shaft gear portion 32a and the rack portion 31a when the transfer head 21 projects can be reliably released State of engagement.

In addition, since the rocking shafts 31c and 31d of the intermediate gear 31 are guided by the guide portion 9 (the left rocking shaft guide hole 33a and the right rocking shaft guide groove 52n) which are longer in the front-rear direction, they have both The support function of the rocking shafts 31c and 31d and the guide function of the intermediate gear 31 can reduce the volume of the overall structure.

Accordingly, the rack portion 31 a of the intermediate gear 31 synchronized with the backward movement of the transfer head group 20 and the supply bobbin drive shaft gear portion 32 a that is rotatably connected to the supply bobbin 82 are used to implement the transfer head 21 The winding operation of the transfer belt T at the time of retracting. In addition, since the intermediate gear 31 or the slider portion 22 of the transfer head group 20 is formed in a plate shape, the coating film transfer tool 10 having a simple structure and saving space can be configured.

The coating film transfer tool 10 is provided on the case body 5 side, and includes a transfer head 21 or a rotation coupling mechanism 30. Thereby, since the number of components mounted on the replacement core 80 which is discarded after replacement can be reduced, it is possible to provide the coating film transfer tool 10 which reduces component waste.

When the transfer belt T is rewound, the clutch mechanism 4 operates as follows.

The amount of rewinding of the transfer belt T per rotation of the supply bobbin 82 varies depending on the remaining amount of the unused transfer belt T that is wound on the supply bobbin 82. Specifically, when the remaining amount of the unused transfer belt T wound on the supply bobbin 82 is large (that is, when the outer diameter of the transfer belt T in the supply bobbin 82 is large) , The amount of rewinding will be smaller than the remaining amount (that is, the outer diameter of the transfer belt T in the supply tube 82 is smaller). Here, in this embodiment, since the clutch mechanism 4 is provided between the first supply bobbin drive shaft 37 and the second supply bobbin drive shaft 32, it is not subject to unused rotation that is wound into the supply bobbin 82. With the influence of the remaining amount of the printing tape T, the rewind amount of the supply bobbin 82 can be set to a certain amount. Thereby, regardless of the remaining amount of the unused transfer belt T wound onto the supply bobbin 82, even if the protruding and retracting operation of the transfer head 21 is performed, the coating film of the unused transfer belt T can still be frequently applied. The separation line is positioned on the transfer roller 21a.

Specifically, for example, when the retreating stroke of the transfer head 21 is set to 10 mm, the 10 mm transfer belt T is rewinded while the transfer tube 82 is not yet wound on the transfer tube T, and the supply tube driving shaft is implemented. Setting of the number of teeth of the gear portion 32a and the rack portion 31a. That is, the number of teeth of the supply bobbin drive shaft gear portion 32a and the rack portion 31a is set so that the rewind amount of the supply bobbin 82 is formed while the outer diameter of the transfer belt T in the supply bobbin 82 is minimized. It is 10mm.

With this setting method, when an unused transfer belt T is wound into the supply tube 82 in a large amount in the initial state, for example, a 15 mm rewind may occur. Even in this case, during the movement toward the rear of the intermediate gear 31 (the rack portion 31 a), the reverse rotation prevention mechanism 6 of the take-up bobbin drive shaft 35 is applied to apply a tensile force to the transfer belt T, The clutch mechanism 4 is actuated, and the second supply bobbin drive shaft 32 appropriately rotates relative to the supply bobbin 82 and the first supply bobbin drive shaft 37. Accordingly, the amount of rewinding of the supply bobbin 82 is formed to 10 mm. Thereby, the amount of rewinding of the transfer belt T can be set to a fixed value without being affected by the remaining amount of the unused transfer belt T wound on the supply bobbin 82. In this way, regardless of the remaining amount of the unused transfer belt T wound on the supply bobbin 82, the separation line of the coating film of the transfer belt T can be regularly positioned on the transfer roller 21a.

As mentioned above, although the embodiment of this invention was described, this invention is not limited to this embodiment, It can implement various aspects. For example, although the coating film transfer tool 10 in the present embodiment is provided with a correction belt as the transfer belt T, it is not limited to this, and various types of coating film transfer belts such as a tape adhesive may be used. . In addition, although the intermediate gear 31 has a slightly L-shaped plate shape, it is not limited to this, and may be various types such as gears and the like disclosed in the prior art, such as gears that move together as the transfer head group 20 moves back and forth. In addition, regarding the clutch mechanism 4, if the other shaft is inserted into the cylindrical shaft portion as shown in this embodiment, it can be formed with a simple structure, but it can also be set as a friction plate or an elasticity formed separately. The component is a clutch mechanism that implements other forms such as pressing. [Industrial availability]
