[0002]

2. Description of the Related Art In recent years, the trend toward fashion has been remarkably increasing, and nail art for designing hands and toenails has attracted attention. The basic method of designing nails is to apply colors to your nails using special paints, etc.
Drawing shapes, photographs, characters, etc., requires special skills and talents in order to design well, and it is not easy to apply design especially to dominant nails, even if it is an expert. But it was very troublesome.

Therefore, a nail salon in which specialists design nails of applicants has been started, but it has not yet been widely used because the cost burden on users is high and it is not economical. Artificial nails made of synthetic resin (artificial nails) were designed and applied to their own nails using double-sided adhesive tape, etc. There was a problem that the design had to be done by oneself, which was troublesome, and that the shaping as an artificial nail took time.

[0004] Furthermore, in consideration of the simplicity that anyone can use, stickers and the like that can be applied to the surface of own nails or artificial nails have been developed, but it is difficult to apply any design, and the unique artistic effect is exhibited. There was a problem that it was not possible. In such a situation, the inventor has developed a false nail base material that the user can freely design and a false nail using the same, and filed a patent application (Japanese Patent Application Laid-Open No. 11-89626). ).

[0005] This false nail is thermally transferred to a substrate made of a film or a sheet having a size capable of giving a false nail display such as a color, a graphic, a photograph, a character, or the like on one side thereof, by PPC,
Using a printing device such as a pen plotter or inkjet,
The user of the artificial nail selects and determines an image for artificial nail display such as an arbitrary color, figure, character, etc. from the image data in the printing device, and prints and displays the image on the base material. In addition, each of the artificial nails is formed into a curved shape.

[0006] The shape of the false nail after being formed into a curved shape may be formed with a notch for breaking so that the false nail can be broken from the base material along the false nail indication, if necessary.

[0007]

Heretofore, the inventor of the present invention has provided a step of curving a film or a sheet on which an artificial nail indication has been given as an artificial nail shape along the artificial nail indication as described above. It has been considered to separately perform a step of forming a cut for breaking so that the cut can be made from the substrate. However, in this case, not only the number of steps for manufacturing false nails is increased, but also it is difficult to perform the curved forming of the film or the sheet and the formation of the cut for breaking with high accuracy without causing a positional shift. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel false nail punching die which can perform the bending process and the breaking notch forming process in one step with high accuracy.

[0009]

Means for Solving the Problems and Effects of the Invention In order to solve the above-mentioned problems, the inventor firstly formed a concave portion having a flat plate-like shape and having an inner peripheral shape corresponding to the shape of a cut for breaking on the upper surface thereof. Forming, at the corner between the inner peripheral surface of the concave portion and the upper surface of the flat plate, a cutting blade for forming a cut for breaking is provided, and the bottom surface of the concave portion has a convex curved shape corresponding to the curved shape of the artificial nail. And the lower mold, and a convex portion having an outer peripheral shape corresponding to the shape of the cut for breaking, which can be inserted into the concave portion of the lower mold, the outer peripheral surface of the convex portion, and a lower end surface facing the lower mold. At the corners, while providing a cutting blade for forming a cut for breaking, the lower end surface, an upper mold having a concave curved shape corresponding to the curved shape of the false nail, using a punching die having, The step of bending and the step of forming a cut for breaking are performed at once. It was 討.

That is, when at least one of the two molds is heated to the vicinity of the softening point of the film or sheet and the film or sheet is sandwiched between the two molds, a cutting notch is formed by the cutting edge of both molds. At the same time, the area within the breaking notch, which is sandwiched between the lower end surface of the upper mold convex portion and the bottom surface of the lower mold concave portion, of the film or sheet is curvedly formed as an artificial nail shape. However, in the above-mentioned die, since the upper die and the lower die are both formed of a hard material such as a metal or ceramics, it is apparent from the subsequent studies by the inventors that the following various problems may occur. It became. (1) When the two molds are combined, the lower end surface of the upper mold convex portion and the bottom surface of the lower mold concave portion do not come into contact with each other. In order to achieve this, in addition to both types of cutting blades for forming the cut for breaking, the both surfaces are processed and formed with high processing accuracy so as to maintain a constant interval over the entire surface. Required, and the production cost of the die is high. (2) Both molds need to be aligned with high accuracy in the plane directions (X, Y directions) including the upper surface of the flat plate of the lower mold when incorporated into the device for curve molding and notch formation. In addition, when the molds are combined, when the lower end surface of the upper mold protrusion and the bottom surface of the lower mold recess do not contact each other as described above, and when the film or sheet is sandwiched between these two surfaces, The opening and closing directions (Z
Direction), it is necessary to perform alignment with high dimensional accuracy, and it is particularly difficult to align the latter, which is the movable direction of the mold, in the Z direction. (3) It is difficult to maintain the alignment in the Z direction because the stress of opening and closing the mold is applied during use of the device, it is easy to cause a shift, and when a shift occurs in a direction in which both molds approach, the upper mold is closed. The lower end surface of the convex portion and the bottom surface of the concave portion of the lower mold come into contact with each other, and these surfaces are scratched, and the scratches may be transferred to the false nail at the time of curve molding, and the appearance of the false nail may be significantly impaired. is there. Further, when the two molds are displaced in the direction in which the two molds are separated from each other, there is a possibility that the film or the sheet cannot be curved and formed clearly.
Therefore, in addition to the problem (2), maintenance of the device becomes difficult. (4) The cutting notch after the notch for breaking is formed and curved is fitted in the recess of the lower mold, and even in a part thereof, the original film or sheet is connected by the connecting material. Even if it is connected, it may not be easy to take it out of the recess, and if the connecting material is cut and the false nail remains in the recess, it cannot be easily taken out.

Then, as a result of further study, a surface corresponding to the bottom surface of the concave portion of the lower die is formed on the upper end surface of a receiving member which is a separate component detachable from the lower die, and the receiving member is made of metal or the like. It has been found that all of the above problems can be solved by using an elastic material such as rubber instead of a hard material, and the present invention has been completed. That is, the false nail cutting die of the present invention forms a cut for breakage on a film or a sheet on which false nail indications such as colors, figures, photographs, characters, etc. have been made so that the film or sheet can be broken along the false nail indication. Together with a punching die for curved molding as an artificial nail shape, (a)
In the form of a flat plate, the upper surface thereof is formed with a concave portion having an inner peripheral shape corresponding to the shape of the cut for breaking, and at the corner between the inner peripheral surface of the concave portion and the upper surface of the flat plate, for forming the cut for breaking. A lower mold provided with a cutting edge, and (b) a convex portion having an outer peripheral shape corresponding to the shape of the cut for breaking, which can be inserted into the concave portion of the lower die, the outer peripheral surface of the convex portion, At the corner with the lower end face facing the mold, while providing a cutting blade for forming a cut for breaking, the lower end face, the upper mold having a concave curved shape corresponding to the curved shape of the false nail, (c) The upper end face that is inserted and placed in the recess of the lower mold and faces the upper mold,
And a receiving member formed entirely of an elastic material and having a convex curved shape corresponding to the curved shape of the artificial nail.

In the punching die for false nails of the present invention, the surface of the lower die corresponding to the bottom surface of the concave portion as described above is
Since it is formed on the upper end surface of a receiving member made of an elastic material such as rubber, which is a separate component from the lower die, even if the upper end surface contacts the lower end surface of the convex portion of the upper die, the lower end surface is There is no risk of being scratched. Further, when a film or a sheet is sandwiched between the upper end surface of the receiving member and the lower end surface of the upper mold convex portion, the film or sheet is substantially evenly formed on the lower end surface of the upper mold convex portion by the elasticity of the receiving member. Is pressed into the shape, and it is curved and formed neatly.

Therefore, the cutting die for false nails according to the present invention is characterized in that only the upper and lower cutting edges and the lower end surface of the upper die convex portion are processed with high precision.
It only needs to be formed, and the manufacturing cost can be lower than before. In addition, when both types are incorporated into an apparatus, only the X and Y directions need to be aligned with high precision, and the Z direction can be roughly adjusted. In addition, when the apparatus is used, a slight shift occurs in the Z direction. Since there is no problem, the maintenance of the device can be performed more easily than before.

Further, when the mold is opened after the breakage notch is formed and curved, the false nail is automatically pushed out of the lower mold recess by the restoring force of the receiving member. There is no possibility that the problem that the false nail remains in the concave portion will occur. Therefore, according to the false nail punching die of the present invention, the step of bending and the step of forming a notch for breaking can be performed in one step without causing various problems such as the above (1) to (4). In addition, it can be performed with high accuracy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing an example of the embodiment. As shown in FIG. 1, the punching die for false nails of this example has a pair of lower die 1 and upper die 2 both formed of a hard material such as metal or ceramic, and a through hole as a recess of the lower die 1. And a receiving member 3 made of an elastic material such as rubber and inserted and disposed in the receiving member 3.

The lower die 1 is formed as a thick flat plate as a whole. The lower die 1 is penetrated from the upper surface 11 to the lower surface 12 of the flat plate 10 to form an inner peripheral shape corresponding to the shape of the cut for breaking. The through-hole 13 is formed as a concave portion, and a cutting edge 14 for forming a cut for breaking is provided at a corner between the inner peripheral surface 13a of the through-hole 13 and the upper surface 11 of the flat plate. . Further, in the case of the example shown in the figure, the cutting blade 14 has a body portion 14a corresponding to the outer shape of the false nail itself, and a connecting member projecting upward and rightward from the figure to connect the false nail to the original film or sheet. And a small protruding portion 14b corresponding to the outer shape.

On the other hand, the upper mold 2 has a convex portion 20 which can be inserted into the through hole 13 of the lower die 1 and has an outer peripheral shape corresponding to the shape of the cut for breaking, and the convex portion 20 is connected to its upper end side (see FIG. Although the upper mold 2 is shown upside down, it is on the lower side.)
And a thick flat base 21 supported by the
In addition to providing a cutting edge 22 for forming a cut for breaking at a corner between the outer peripheral surface 20a of the lower mold 1 and the lower end surface 20b facing the lower mold 1, the lower end surface 20b is formed in a concave shape corresponding to the curved shape of the false nail. It has a curved shape.

In the case of the example shown in the figure, the cutting blade 22 connects the body part 22a corresponding to the outer shape of the artificial nail itself to the artificial nail or the original film or sheet projecting from the upper right in the figure. Small protruding portion 22b corresponding to the outer shape of the connecting member
And By setting the length of the small protruding portion 22b shorter than the length of the small protruding portion 14b of the lower die 1, as shown in FIG.
The base of the connecting material S2 connecting the original film or sheet S is left without being cut by the two cutting blades 14 and 22.

Further, the receiving member 3 is provided with the through hole 1 of the lower die 1.
3 has an outer peripheral shape corresponding to the shape of the notch for break, which can be inserted into the upper die 2, and an upper end surface 3 facing the upper die 2.
0 is a convex curved shape corresponding to the curved shape of the false nail. Further, in this example, when the receiving member 3 is inserted into the through hole 13 of the lower die 1 and arranged, as shown in FIG. The thickness of the receiving member 30 is set so as to protrude above the upper surface 11 of the receiving member 30.

Using the false nail cutting die of this example having the above-mentioned parts, a notch for breaking is formed in a film or sheet on which false nails such as colors, figures, photographs, characters and the like are displayed. In order to form a curved shape, first, as shown in FIG. 2A, the lower mold 1 on which the receiving member 3 is set is set.
The film or sheet S is inserted between the upper mold 2 and the upper mold 2 which is arranged upside down from FIG. 1 and is aligned in the X and Y directions. In addition, at least one of the upper and lower dies 1 and 2, preferably the upper die 2 which does not always contact the receiving member 3.
Is heated to near the softening point of the film or sheet S in the same manner as before.

Next, after the not-shown false nail indication formed on the film or sheet S is aligned with both molds 1 and 2, the upper mold 2 is lowered as indicated by the white arrow in the figure.
Then, as shown in FIG. 2 (b), the portion of the film or sheet S, which indicates the false nail, is attached to the upper mold 2.
It is sandwiched between the lower end surface 20b of the convex portion 20 and the upper end surface 30 of the receiving member 3, and is pressed almost uniformly to the lower end surface 20b by the elasticity of the receiving member 3 as described above, so that the curved shape is neatly formed. Is done.

At the same time, the receiving member 3 is compressed by the pressing force of the upper die 2, and the projection 20 of the upper die 2 is
Is inserted into the through hole 13 of the connecting member S as described above.
A cutting notch for breakage (indicated by reference numeral S3 in FIG. 3) is formed around the curving false nail S1 by the two cutting blades 14 and 22 except for the base portion of No. 2. Thereafter, when the upper mold 2 is raised as shown by a black arrow in FIG. 2C, the false nail S1 pushed into the through hole 13 of the lower mold 1 is moved to the receiving member 3.
Is automatically pushed out of the through hole 13 by the restoring force of the above, and a series of operations is completed.

In the above description, for convenience, the lower mold 1 and the upper mold 2 for forming one false nail shown in FIGS.
However, in practice, it is efficient to simultaneously form a plurality of false nails S1 on one film or sheet S as shown in FIG. 3, for example. , Having a large number of through-holes, the receiving member is inserted into each through-hole, respectively, or a lower mold in which the upper mold having a number of convex portions corresponding to the number of the through-holes is used, Alternatively, the lower mold 1, the upper mold 2, and the receiving member 3 in FIGS.
To form an artificial nail S on a single film or sheet S
It is preferable to use a plurality of them in a row according to the number of 1.

As shown in FIG. 3, the number of false nails S1 formed on one film or sheet S is set to be larger than the number of fingers, and the size of each is set to be different from the right and left by one. Then, there is an advantage that it is possible to flexibly respond to the size of each user's nail. For example, a user with a large nail selects a total of 10 pieces, each of which has the largest size (the leftmost one in the figure) of the artificial nails S5, each of which has a larger size, and a user with a smaller nail has the most. A total of 10 pieces are selected for each of the 5 small-sized ones including the small ones (the rightmost ones), and the intermediate user selects one of the five arbitrary pieces in the middle.
Usage methods such as selecting and using 0 pieces are possible.

The false nail cutting die of the present invention is used by being incorporated in an artificial nail manufacturing apparatus B as shown in FIG. 4, for example. The operation unit on the front of the manufacturing apparatus B displays image data for displaying an artificial nail such as an arbitrary color, figure, photograph, character, etc. prepared in advance on the apparatus, and a user of the artificial nail displays a pointing device B ₁ for inputting an image selected from the image data to the device,
And display B ₂ for confirming the selected display is arranged.

Further, inside the manufacturing apparatus B, a step of printing on the surface of the film or sheet S based on the above-mentioned input result, and a step of cutting the false nail of the present invention on the printed film or sheet S is performed. Using, while forming a notch for breaking so that it can be broken, the step of curving and forming as an artificial nail shape sequentially, means for automatically performing, a number of films cut to a predetermined size or The sheet S or the film or sheet S obtained by winding a large number of sheets into a single roll is sequentially conveyed to each of the above-described units, and then the film or sheet S on which the false nail S1 is formed is manufactured by the manufacturing apparatus B. and conveying means for discharging the bottom of the outlet B ₃ are arranged.

The printed film or sheet S has
Sometimes a protective film for printing protection is laminated,
In that case, prior to the step of forming a cut for breakage using an artificial nail punching die, and curving the artificial nail shape, a step of laminating both by heat bonding may be added, Alternatively, a protective film may be laminated by thermal bonding simultaneously with these operations in the step of forming a cut for breaking using the above-mentioned false nail cutting die and forming a curved shape into the shape of an artificial nail.

[0028] Users of nails attached, according to such a device, desired color, graphic, photo, by selecting an image display nail such as characters input by the pointing device B _1, it displays B ₂ above , The film or sheet S on which a large number of false nails are formed can be automatically obtained as shown in FIG. Then, the user may cut off the individual nails and then attach them on their own nails using, for example, a double-sided tape.

At this time, since the false nail S1 is made of a flexible film or sheet, it is easy to cope with the nail shape of an individual by utilizing its flexibility. In addition, in the manufacturing apparatus B,
It is also possible to incorporate a means for capturing the nail shape of each user as an image with a CCD camera or the like, matching the nail shape data prepared in advance, and changing the print shape or the formed shape. In addition, C
A means for capturing an image with a CD camera or the like, synthesizing it with an image prepared in advance, and using it as a false nail display may be incorporated.

The manufacturing apparatus B of the above-mentioned example automatically performs the steps up to the forming step using the false nail punching die of the present invention. However, the manufacturing apparatus B performs printing or thermal bonding of the protective film. The steps after molding using the false nail punching die may be arbitrarily performed by the user by setting the apparatus in a separately prepared device (not shown). In this specification, the names of the upper mold and the lower mold are used for convenience, however, the false mold for the false nail of the present invention, the upper mold is lower,
The lower mold may be used with the upper mold up, or both molds may be arranged sideways to use.

In addition, appropriate design changes can be made without departing from the spirit of the present invention.
