Stamping face of penetrating type stamp

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamping surface of a penetration stamping mechanism made of a thermoplastic resin having a continuous bubble, and more particularly to a stamping surface of a penetration stamping mechanism capable of forming a dense stamp image.

The penetrating stamp mechanism applies light or heat to the stamping surface made of a thermoplastic resin having a continuous bubble while applying a light or heat, and melt-curing the light or heat transmitted portion, thereby stamping characters or images of the film. It is known that there is. The seal formed by the stamping surface is formed by injecting ink penetrated into the resin having a continuous bubble of a portion which has not been melt-cured by the stamp.

Therefore, in an image in which the bright and dark areas of the seal are clear, such as letters, a clear ink can be formed by sufficiently bleeding out of ink from the pores forming the stamping surface.

However, in the case where the dark and dark areas are mixed, such as an image, or when the image is represented by the difference in the tone, the ink spreads to adjacent pixels if too much ink is supplied from the stamping surface with respect to the predetermined pixel. Inyoung becomes obscure.

In particular, in the case of forming a stamping surface based on a digital image such as a digital camera image, even if a stamping surface having a high resolution can be formed using data having a high resolution, it is not clear when the stamping is actually performed. There is a problem that can only be realized.

In order to solve the problems of the prior art as described above, the amount of ink supplied to a medium such as paper can be controlled from each bubble of a stamping surface made of a thermoplastic resin having a continuous bubble, and a high resolution printing can be realized. It is an object to provide a stamping surface of a penetrating stamp mechanism.

According to the above invention, the ink supply at the time of stamping becomes a small quantity or a suitable quantity, and a clear phosphorus can be formed. Although it is preferable to make it thinner from a viewpoint of reducing the amount of ink accumulate | stored in the whole stamp surface, the stamping surface which has the thickness (0.4-1.2 mm) disclosed in this invention is suitable from the viewpoint of manufacture and use.

Furthermore, in order to form the thin layer of 0.4-1.2 mm in thickness, it is preferable that the bubble ratio is 65 to 85%. It is because it is difficult to shape | mold or slice into a thin layer, when foam ratio is too high. When the bubble ratio is set to 64 to 85%, the amount of ink accumulated in the bubble becomes an appropriate amount without overflowing, and an amount of ink supplied to the stamping surface does not overflow even when stamping, resulting in a clear print. Can be formed.

Moreover, in the said invention, it is preferable that the stamping surface of a penetration type | mold stamping mechanism is a thin layer of 0.4-2.1 mm in thickness, and is comprised from the polyurethane-type resin of 65-85% of foam ratios.

The ink holding layer made of a thermoplastic resin that is continuous to the marking surface layer forming the marking surface and has the same continuous bubble as the marking surface layer is supplied with ink from the marking surface and holds the ink. Then, the ink held by the force applied during stamping is extruded, soaks out to the stamped surface to form phosphorus. As described above, when ink is supplied from the ink holding layer of the stamping surface having the continuous bubbles, a small amount of ink corresponding to the fine pixels is supplied from the continuous bubbles of the ink holding layer having the small bubbles in the thin layer, thereby providing clear You can form a seal. Moreover, it is preferable to make the said stamping surface into a polyurethane-type resin.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described.

Stamping surface of penetrating stamping mechanism

The thermoplastic continuous porous body used in the present invention is not particularly limited, but is preferably an elastomer of polyethylene, polypropylene, and styrene such as polyethylene, polypropylene, and polystyrene, including polyurethane resins. . It is preferable to employ | adopt these thermoplastic resins which have melting | fusing point of 190 degreeC-210 degreeC.

In addition, the continuous foaming of the thermoplastic resin is not particularly limited, but a method of treating with an inorganic acid dissolving calcium arsenite or calcium luterate in a polyolefin resin (for example, JP-A-A) SO 47-39212), non-ionic surfactants or polyatomic alcohols, water insoluble in organic solvents or thermoplastic polyolefin resins of soluble powdery materials in acidic aquatic solutions, obtained during molding The method of washing a molded object with water (for example, refer Unexamined-Japanese-Patent No. 57-42651) is mentioned. In addition, a method of breaking bubbles by using a needle punch or the like in a foam having an independent bubble can also be used.

The thermoplastic resin having a continuous bubble obtained by the above method is molded and / or sliced to a thickness of 0.4 mm to 1.2 mm to become a material of the stamping surface. The stamping surface preferably has a bubble ratio of 65 to 85%. In addition, when the average cell diameter of the bubble is 20 to 50 µm and / or the Ascal C hardness is 30 to 70 °, clear printing can be realized.

The stamping surface of the permeable stamping mechanism is formed by applying light or heat to the stamping surface made of a thermoplastic resin having a continuous bubble while strongly applying a negative film, and melt curing the portion where the light or heat is transmitted. Specifically, the mask film is directly applied to the foam, the heating wire (or light ray) is selectively irradiated, and the portion of the bubble that is hardened by absorbing the heating wire (or photon) is destroyed, and the air bubble is not absorbed without absorbing the heating wire. Forms part. Then, when the ink penetrates the stamping surface and stamps, the ink contained in the bubble (the portion where the bubble is not destroyed by heat irradiation) bleeds out, and the ink does not bleed out in the portion where the bubble is destroyed during the heat irradiation. Therefore, the phosphorus is formed by both of these parts (see Japanese Patent Laid-Open No. 6-155698). In addition, the original image used as said negative film may be a digital image by photography | photography with a digital camera.

The penetrating stamp mechanism of the present invention and its stamping surface are shown in FIGS. 1 and 2. As shown in FIG. 1, the penetrating stamp mechanism 10 generally consists of a stamping surface 1 and a holder 2 supporting the stamping surface 1. The stamping surface 1 of the present invention is used as a stamping mechanism 10 mounted at the tip of the holder 2 of the stamping mechanism 10. The stamping surface 1 is made of a thin layer of resin having a continuous bubble, but the imprinted surface layer 11 in which the resin is dissolved by the imprinted hot wires (or light rays) and the ink supply layer for holding and supplying ink ( 12).

Ink is required to form the phosphorus, which is generally supplied from an ink tank installed inside the holder (back supply) and from an ink holder in surface contact with the outer surface of the stamping surface (surface supply). There is). In the present embodiment, unlike the above, a sufficient amount of ink is applied to the outer surface of the stamping surface in advance, and left to stand for several minutes to pass the ink holding layer 12 (continuous bubble) through the stamped surface layer 11 of the stamping surface. The branches were penetrated into the inside of the thin layer resin), and then, by wiping off excess ink, a means for supplying ink from the ink supply layer 12 was employed. By performing the ink supply once, the stamp mechanism of the present embodiment enables 100 stamps. In addition, since the ink is retained on the stamping surface, it is preferable to cover and store the cap (cap 3 shown in Fig. 2) after use.

FIG. 2 is an X-X cross-sectional exploded view of the stamp mechanism 10 shown in FIG. 1. The cap 3 covers the stamping surface 1 to prevent drying of the stamping surface. The stamping surface 1 made of a thermoplastic resin having a continuous bubble of a thin layer holds the imprinted surface layer 11 to be imprinted and the ink supplied from the outer surface of the imprinted surface layer 11, and again on the imprinted surface 11. The ink holding layer 12 to supply is provided. The thickness of the stamping surface 1 is represented by "t" in FIG. In the said embodiment, the thickness of the stamping surface 1 was 0.4-1.2 mm. The thickness of the stamping surface 1 is the sum of the thickness of the stamping surface layer 11 and the thickness of the ink holding layer 12. Here, since the imprinted surface layer 11 is an image formed by melting by light or heat, the thickness is very thin. In the present embodiment, the stamping surface 1 is provided on the upper surface of the elastic layer 4, so that the force applied at the time of stamping forms a clear phosphorus dispersed on average throughout the stamping surface 1. did.

As described above, the stamping surface of the penetration type stamping mechanism made of a polyurethane-based resin having a thickness of 0.4 to 1.2 mm and having a bubble ratio of 65 to 85% of continuous bubbles has a small average cell diameter and an appropriate hardness. . For this reason, at the time of stamping, only a small amount of ink supplied in the continuous bubble is supplied in a range corresponding to the fineness of the pixels of the stamp plate, so that the pixels can express fine images clearly and are photographed and photographed. The same image can be realized.

Inyoung

The original image was created based on the image data photographed with the digital camera, and the stamping surface (FIG. 3A) which concerns on this invention created based on this was compared with the conventional stamping surface (FIG. 3B). Figure 3 shows a print a using a stamping surface 1 of the penetrating stamping mechanism according to the invention and a print b using a conventional stamping surface.

3a is a drawing when the stamping surface 1 of the penetrating stamping mechanism according to the invention is used. Inyoung is a digital image of a person photographed with a digital camera as an original image, but the face of the person appears as a photographic image. This is because the stamping surface 1 is made into a thin layer with a thickness of 0.4 to 1.2 mm, and only a small amount is supplied in the range corresponding to the fineness of the pixels of the stamping plate, when the ink containing continuous bubbles having a bubble ratio of 65 to 85% is supplied. This is because the pixels can express the fine image clearly.

On the other hand, Fig. 3B is a phosphor formed by a stamping surface supplied with ink (surface supply) in an ink holder which is in surface contact with the outer surface of the stamping surface. Unlike the print of FIG. 3A, ink is supplied in large quantities, and this spreads and the outline of the characters is blurred. This makes it possible to reliably read a character, but it is impossible to clearly express an image with fine pixels like a portrait.

As described above, the difference occurs in the printing, because the stamping surface according to the present invention is made into a thin layer having a thickness of 0.4 to 1.2 mm, and the material is made of a polyurethane-based resin having a continuous bubble of 65 to 85% of the bubble ratio. to be.
