Description

  The present invention relates to a transfer tool. More specifically, the tension can be relaxed even when the tension of the transfer tape is increased and the feeding resistance is increased. In particular, even when a long transfer tape is used as a target, the tension is smooth. It is related with the transfer tool which can implement | achieve the coating film transfer which becomes.

By using a transfer tape in which a white coating film for concealment is laminated on one surface of a belt-like base tape, the transfer head is pressed against the transfer surface in a state where the transfer tape is wound around the transfer head. A transfer tool capable of transferring a film is widely used.
The transfer tool includes a feeding core that supports a transfer tape wound in a roll shape so that the transfer tape can be fed, a winding core that winds up the base tape, and a transfer head around which the transfer tape is wound. Since the winding diameter of the transfer tape in the feeding core is large and the winding diameter of the base tape of the winding core is small, the transfer tape can be smoothly fed out.
However, there is a characteristic that the tension increases as the winding diameter of the transfer tape on the feeding core side becomes relatively small. For this reason, the actual length of the transfer tape wound around the feeding core is, for example, about 10 m, and there is a problem that the frequency of replacing the transfer tape increases.

Therefore, Patent Document 1 proposes a transfer tool that can relieve the tension of the transfer tape and reduce the feeding resistance by displacing the rotation center of the winding core so as to approach the feeding core side. Yes.
Japanese Patent Laid-Open No. 2002-28395

The transfer tool described in Patent Document 1 adopts a configuration in which the relative distance between the winding core and the feeding core is shortened when a transfer force is applied by pressing the transfer head against the transfer surface. .
However, since the transfer force applied to the transfer head does not coincide with the moving direction of the take-up core and is applied in a direction inclined by a predetermined angle, even if transfer force is applied to the transfer head. Depending on the degree of inclination, there is an inconvenience that the winding core cannot move smoothly toward the feeding core. In this case, as a result, the tension is not sufficiently relaxed and the feeding resistance is not reduced, so that the transfer operation becomes difficult especially at the end of use of the transfer tape. Such inconvenience becomes more difficult when the length of the transfer tape is, for example, about 25 m, and the transfer itself becomes impossible.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to provide a transfer head along the direction in which a pressing force is applied during transfer when the tension of the transfer tape reaches a predetermined tension. Even when the take-up core is moved closer to the feeding core side and the tension is relaxed to achieve smooth feeding, and even for long transfer tapes, the transfer tape It is in providing the transfer tool which can be consumed to the last.

To achieve the above object, the present invention provides a feeding core that is disposed in a case and supports a transfer tape provided with a coating film on a base tape so that the transfer tape can be fed, and a transfer head on which the transfer tape is wound around And a transfer tool comprising a winding core for winding the base tape,
A holder for supporting the transfer head and the winding core located in the case, and a position regulating member for keeping the holder in an initial position,
The holder is rotatably provided in a direction in which when the predetermined pressing force is applied to the transfer head, the transfer head is displaced by a predetermined angle and at the same time the rotation center of the winding core is displaced toward the feeding core. The structure is adopted.

  In the present invention, the holder is configured to be rotatably supported by the case at a position away from the center of the winding core.

  Further, the position regulating member is configured by an elastic member provided so that one end is engaged with the case, and the other end is engaged with the holder, and the elastic member is elastically deformed. The holder can be provided to allow rotation.

According to the present invention, when the tension of the transfer tape reaches a predetermined tension, the transfer head is displaced by the reaction force of the transfer force, and at the same time, the rotation center of the winding core and the rotation center of the feeding core are close to each other. As a result, the tension is relaxed and the feeding resistance can be reduced. At this time, the transfer head is configured so that when the transfer force is applied, the take-up core is displaced at the same time as the transfer force is applied, the relative distance between the take-up core and the feed core is ensured. It will be shortened.
Moreover, since the said holder has a rotation center in the position away from the center of the said winding core, the said movement can be performed smoothly.

  As shown in FIG. 11, the cover 17 includes a support shaft 86 and a cover portion 88 having a substantially square shape in plan view, which is connected in a direction orthogonal to the axial direction of the support shaft 86. . One end side of the support shaft 86, that is, the lower end side in FIG. 11A is formed as a tapered portion 86A, while the other end side is formed as a large-diameter operation portion 86B. The tapered portion 86A is received in a circular hole 71 formed in the surface of the leaf spring portion 65 of the first holder forming body 16A, while the operating portion 86B is an operating hole of the second holder forming body 16B. 82.

It is designed to engage with the peripheral wall. The coil spring 87 normally biases the cover 17 so that the cover 17 takes an open position along the outer periphery of the holder 16 or the case 11.

  In the present embodiment, the position restricting member 18 is composed of a rod-like elastic member. As shown in FIG. 12, the position restricting member 18 includes an elongated plate-like linear portion 90, a curved portion 91 formed on one end side of the linear portion 90, and a corner provided on the other end side. Part 92. A circular hole 93 is formed in the corner portion 92, and the convex portion 67 formed in the first holder forming body 16 </ b> A fits in the hole 93, while the curved portion 91 has a first shape. Thus, the position restricting member 18 restricts the initial position of the holder 16 accommodated in the case 11.

  Next, an assembly method and transfer operation of the transfer tool 10 according to the present embodiment will be described with reference to FIG.

  When the transfer tool 10 is assembled, the position restricting member 18 is arranged in the flat surface portion 22 of the first case 11A. As shown in FIG. 1, the position restricting member 18 is arranged in an inclined posture so that the curved portion 91 is in contact with the rib 25, while the corner portion is located obliquely lower left in the drawing. The Then, the feeding core 12 is mounted around the support cylinder 24.

On the other hand, the first head support shaft 63 of the first holder forming body 16A of the holder 16 is inserted into the support hole 55 of the transfer head 15, and the transfer head 15 is fixed. Then, the winding core 13 to which the tip of the transfer tape T is fixed in advance is set so that the upright cylinder 61 is positioned in the rotation center hole 48.
In the state where the mounting of the transfer head 15 and the winding core 13 is completed in this way, the second holder forming body 16B is assembled to the first holder forming body 16A. At this time, the tapered portion 86A of the support shaft 86 of the cover 17 is received in the circular hole 71 of the leaf spring portion 65, and the operation is performed in the operation hole 82 formed on the second holder forming body 16B side. Position part 86B. Then, the cylindrical portion 79 and the insertion shaft portion 80 of the second holder forming body 16B are fitted or abutted with the cylindrical portion 64 and the connecting cylinder 66 of the first holder forming body 16A. Assembling of the holder 16 is completed by fitting the peripheral walls partially formed on the outer periphery of the holder forming bodies 16A and 16B.

  Next, the transfer tape T wound in a roll shape is mounted on the outer peripheral side of the feeding core 12, and the holder 16 is mounted in the first case 11A. For this mounting, the cylindrical body 27 formed in the first case 11A is inserted into the cylindrical portion 64 and the cylindrical body 79 of the holder 16, and the convex portion 67 formed in the first holder forming body 16A is This is performed by fitting into a hole 93 formed in the corner portion 92 of the position regulating member 18, whereby the holder 16 is set at the initial position shown in FIG. 1.

  After the setting of the holder 16 is completed, the second case 11B may be combined with the first case 11A. In this combination, the fitting protrusion shaft 34 and the shaft 37 of the second case 11B are fitted to the support cylinder 24 and the connecting cylinder 28 of the first case 11A, and the peripheral walls of the first and second cases 11A and 11B. This is done by fitting 31 and 39 together. In a state in which the second case 11B is fitted to the first case 11A, the claw piece 50 provided on the winding core 13 is engaged with a ratchet mechanism 76 that meshes with a serrated tooth 76 formed on the inner surface side of the second case 11B. Thus, the winding core 13 is allowed to rotate only in the winding direction.

  When performing the transfer, it is only necessary to hold the case 11 and pull it while pressing the tip of the transfer head 15 against the surface to be transferred. In the transfer operation, at the initial stage of use of the transfer tape T, since the winding diameter of the transfer tape T on the feeding core 12 side is relatively larger than that on the winding core 13 side, the tension is maintained moderately and smoothly. The coating film can be transferred to the transfer surface.

As the consumption of the transfer tape T progresses and the transfer tape winding diameter on the feeding core 12 side becomes smaller,
Since a large force is required to pull out the transfer tape T, when the transfer head 15 is pressed against the surface to be transferred, the holder 16 is displaced toward the feeding core 12 along the transfer force applying direction, and the tension of the rubber belt B is increased. Relax. That is, the transfer head 15 is angularly displaced by receiving a reaction force along the direction in which the transfer force is applied. More specifically, the position restricting member 18 whose one end is engaged with the holder 16 is elastically deformed in the direction of bending at the linear portion 90, and the holder 16 rotates the rotation center shaft 26 about the rotation center 26. As shown in FIG. 13, it is rotated and displaced clockwise in FIG. At this time, at the same time that the winding core 13 approaches the feeding core 12 side, the transfer head 15 is also angularly displaced from the position indicated by the two-dot chain line in FIG. 13 to the position indicated by the solid line, thereby relaxing the tension. As a result, the transfer tape T is smoothly fed and wound. Incidentally, although the rotation angle of the holder 16 in this embodiment is about 5 degrees, the angle is not particularly limited. When the coating film is transferred to the transfer surface, the coating film may be transferred by being dragged over a certain length from the tip of the transfer head 15 to the upstream side in the transfer tape feeding direction. In this case, when the next transfer is performed, the coating film does not exist at the tip of the transfer head 15 and the coating film cannot be transferred. Since the tension is relaxed by the displacement of the feeding core 12 and the winding of the transfer tape T is promoted, the coating film is fed so that it is positioned at the tip of the transfer head 15 and the transfer is performed each time. Can do.

  When the transfer is completed, the position restricting member 18 exhibits an elastic restoring force to return the holder 16 and the transfer head 15 supported by the holder 16 to the initial position to maintain the same position.

  When the transfer operation is not performed, the transfer head 15 is protected by a cover 17. In this case, the free end side of the cover 17 is picked with a fingertip, and is rotated in the direction of arrow a in FIG. Then, when the cover 17 is rotated to the position indicated by the two-dot chain line in FIG. 1, it moves to the position where the side end of the cover 88 is hooked on the step 84 formed on the second holder forming body 16B. As a result, the cover 17 covers and protects the tip of the transfer head 15 and the upstream region of the transfer tape T in the feeding direction. At this time, immediately before the side end portion of the cover portion 88 is hooked on the step portion 84 side, the support shaft 86 of the cover 17 moves in the axial direction so that the tapered portion 86 faces the free end side of the leaf spring portion 65 outward. When the plate spring portion 65 is displaced by being pressed and is caught on the step portion 84, the leaf spring portion 65 is elastically restored, so that the side end portion of the cover portion 88 is kept on the step portion 84.

  On the other hand, when the protection of the transfer head 15 by the cover 17 is released, the fingertip may be applied to the operation portion 86B and pressed. As a result, when the leaf spring portion 65 is displaced by the tapered portion 86B, the axis of the support shaft 86 moves and the side end portion of the cover portion 88 moves in the opposite direction of the step portion 84, the coil spring 87 is attached. The cover 17 returns to the initial open position by the force.

  Therefore, according to such an embodiment, even if the feeding resistance increases due to a change in tension when the use of the transfer tape T is advanced, the winding core is caused by the rotational displacement of the transfer head 15 and the holder 16. 13 is configured to move closer to the feeding core 12 side, so that the tension can be relaxed and the transfer tape T can be smoothly fed out to transfer the coating film. Therefore, it is possible to provide a transfer tool suitable for use.

  Further, since the cover 17 is integrally provided, there is no possibility of losing the cover 17 and the transfer tape T can be protected as necessary. In addition, since the area to be protected is a portion of the transfer tape T on the upstream side in the feeding direction from the front end of the transfer head 15, that is, only the part where the protection is substantially required is protected, the component shape is compact and It can be formed simply. Further, when the cover 17 is in the open position, the cover 17 is maintained at a position substantially along the outer periphery of the case 11, so that there is no inconvenience that the presence of the cover 17 is in the way.

Although the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, the present invention is not limited to this.
That is, the invention has been illustrated and described with particular reference to particular embodiments, but it should be understood that the above-described embodiments are not deviated from the technical idea and scope of the invention.

  For example, in the above-described embodiment, the transfer tool 10 that transfers the coating film for correction is illustrated and described. However, an adhesive tape, an adhesive, or the like may be laminated and transferred on the base tape BT.

  Further, when a transfer force is applied to the transfer head 15, the transfer tool 10 displaces the holder 16 together with the transfer head 15 so that the rotation center of the winding core 13 approaches the feeding core side. The configuration is sufficient, and other detailed structures can be arbitrarily changed as necessary.
