Description

The present invention relates to a technical field of a transfer head of 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.

The transfer head of a conventional coating film transfer tool has a pressure transfer portion formed at the tip of the transfer head, a lower surface portion on which an unused transfer tape runs, and an upper surface portion on which a substrate tape after transfer is reversed. And a tape guide for restricting the swing of the transfer tape in the width direction is provided at both ends in the width direction of the lower surface and the upper surface of the transfer head. On the other hand, in recent years, there has been a demand for a compact coating film transfer tool or a long transfer tape, and accordingly, a thin transfer tape is required. In order to reduce the thickness of the transfer tape, it is necessary to reduce the thickness of the base tape, and a plastic film is used as the base tape. In the coating film transfer tool using the plastic film as a base tape, the shape of the upper surface of the transfer head in which each tape guide narrows upward in order to prevent deviation of the transfer tape from the transfer head. Has been proposed. (For example, see Patent Document 1)

  In order to prevent the film transfer tape from coming off due to looseness as much as possible, a tape guide has also been proposed in which the top surface portion of the transfer head is opposed to each other and the tip portion protrudes forward from the pressure transfer portion. (For example, see Patent Document 2)

  However, in the tape guide in the conventional coating film transfer tool, when a thin plastic film is used as the base tape, the dynamic friction coefficient is low because the back surface of the transfer tape is treated with a release agent. In addition, since the rigidity is lower than that of the paper base material, the force in the width direction acts on the transfer tape, and even if the width direction swing in the base tape after transfer can be regulated by the tape guide, In the transfer section, the swinging and meandering of the transfer tape cannot be sufficiently controlled, and a problem of detachment from the transfer head occurs, which may cause a running failure, transfer failure, or even unusability.

  Even when using tape guides that are opposed to each other on the upper surface of the transfer head and whose front end protrudes forward from the pressure transfer unit, it is effective for removing the transfer tape. The tape guide protruding forward from the transfer section becomes an obstacle.For example, if the coating film transfer tool is to be transferred in a posture perpendicular to the transfer surface, the coating film does not contact the transfer surface and the transfer is performed. In some cases, the transfer angle of the coating film transfer tool is restricted. For example, the transfer operation can be performed only at a certain angle.

  Even when a thin plastic film is used as the base material of the transfer tape, the present invention prevents the transfer tape from coming off due to the swinging and meandering of the transfer tape when a force that swings the transfer tape in the width direction is applied. A coating film transfer tool transfer head that can stably run the transfer tape, avoid transfer work, and avoid unusable conditions, and is not subject to restrictions on the transfer angle of the coating film transfer tool in normal use. It is intended to provide.

The first invention includes a feeding portion for feeding out a transfer tape provided with a coating film on a base tape, a transfer head that presses and transfers the coating film to a transfer target, and a winding for winding up the base tape after transfer. A coating film transfer tool having a take-off portion, wherein the left and right lengths of the side portions of the transfer head where the base tape does not run in the width direction of the transfer head are in the range of 2 to 10 mm. is there. Here, the side portion refers to a portion that comes into contact with the transferred material when the coating film is transferred by applying the transfer head to the transferred material. Since the left and right ends of the transfer head of a commercially available coating film transfer tool are rounded, generally the entire length of the side portion of the apparent transfer head is in contact with and pressed against the transfer target. It is not a thing. There are many things which do not become the length of the side part said by this application.
A second invention is the coating film transfer tool according to the first invention, wherein the transfer head and the main body of the coating film transfer tool are integrally formed.
A third invention is the coating film transfer tool according to the first invention or the second invention, wherein the material of the transfer head is ABS.
A fourth invention is the coating film transfer tool according to the first to third inventions, wherein the right and left side portions of the transfer head are elastically deformable.

  Since the length of the side portion of the transfer head is longer than the width of the transfer tape, when the coating film transfer tool is pressed against the transfer target and pulled, the meandering of the coating film transfer tool itself is regulated. That is, since the coating film is drawn in a straight line, as a result, the transfer tape does not meander, and running failure and transfer failure can be suppressed. In addition, the transfer head that is integrally formed with the body of the coating film transfer tool in order to reduce the manufacturing cost has a poor transfer tape running compared to the shape that the transfer head swings to fit the transferred object. Although it is easy to generate | occur | produce, if it is the transfer head of this invention, a driving | running | working defect can be suppressed remarkably.

It is the front view and top view of the coating-film transfer tool which are the Examples of this invention. It is the front view and top view of a coating-film transfer tool which are the Example of 2nd invention. It is a perspective view of the coating-film transfer tool of FIG.

  FIG. 1 is a front view and a plan view of a coating film transfer tool of the present invention. The transfer head is rotatable with respect to the axis A of the transfer head. This is a so-called rotary head. Even when the coating film transfer tool main body swings to the left and right when using the coating film transfer tool, the tip of the transfer head can be uniformly pressed against the transfer target by the rotating head. The width of the base tape is 5 mm. The length of the side part of the transfer head where the base tape does not travel is 3.5mm, which is longer than the length of both sides of the conventional transfer head. The coating film transfer tool itself is easy to draw in a straight line without meandering.

  The length of each of the left and right side portions of the transfer head where the base tape does not travel is preferably in the range of 2 to 10 mm. The range of 3 to 7 mm is more preferable. A particularly preferable range is a range of 3.5 to 5 mm. If the length of the side portion is less than 2 mm, it becomes difficult to suppress meandering of the coating film transfer tool. If it exceeds the range of 10 mm, the side portion may be damaged during use or storage, and when it is stored in a pen case or the like, a protrusion protrudes and is difficult to store.

  FIG. 2 is a front view and a plan view of the coating film transfer tool of the second invention. The transfer head and the main body are integrally formed. The transfer head is made of resin and moves up and down slightly in the direction of the arrow shown in FIG. The width of the base tape is 5 mm. The length of each side portion of the transfer head where the base tape does not travel is 3.5 mm, which is longer than the length of both sides of the conventional transfer head.

  The transfer head and the main body of the coating film transfer tool which are integrally molded can be manufactured at a low cost, but it is difficult for the transfer head to uniformly press the transfer material when using the coating film transfer tool. Meandering is likely to occur. However, when the length of both sides of the transfer head is increased, such as a coating film transfer tool, the coating film transfer tool is easily drawn in a straight line, and the substrate tape is less likely to meander.

  The shape that allows elastic deformation of the side portion of the transfer head where the base tape of the transfer head does not travel generally includes a shape that reduces the overall thickness of the side portion. It is also possible to make the side part thinner so that a part of the side part is confined. For example, there is a shape in which a part of the side portion in the boundary surface between the end portion in the width direction of the base tape and the side portion is thinned. However, even if the shape of the side portion is designed so that it can be elastically deformed, it is desirable that the line in contact with the transfer head with respect to the transfer target has a uniform shape as a whole.

  Conventionally, various molding resins have been used as materials for the transfer head. For example, PE (polyethylene), PP (polypropylene), AS (acrylonitrile styrene resin) ABS (acrylonitrile butadiene styrene resin), POM (polyacetal), PA (polyamide), PC (polycarbonate), PPS (polyphenylene sulfide) PBT (poly) Butylene terephthalate), PET (polyethylene terephthalate), HIPS (high impact polystyrene) and the like.

  Among these, PP is particularly preferable as a material for the transfer head because it can easily adjust the amount of elastic deformation on both sides and has appropriate rigidity. The transfer head shown in FIG. 1 is particularly preferably used as a rotary head type.

As a material of the transfer head when the transfer head and the main body are integrally formed, ABS is preferable because it can easily adjust the elastic deformation amount on both sides and has an appropriate rigidity.
