JPS58158280A - Ink impregnator for type body, roller, etc. - Google Patents

Abstract

PURPOSE:To enable both stamping and printing with ink impregnated into type body, roller, etc., to be performed by a method in which fine powder of a metal or inorganic substance is temporarily solidified and sintered to form a solid material having a specific porosity and then ink is impregnated into the solid material. CONSTITUTION:An appropriate amount of a metal or inorganic fine powder is put in a mold with a concave or convex letter pattern, etc., and then pressed under a proper pressure to raise the density of the compressed fine powder. The fine powder is temporarily solidified with a binder to prevent the degradation of the shape of molding and thereby to make the separation and moving of the molding from the mold easier. Then, the molding is dried, separated from the mold, and put in a sintering furnace for sintering. The product X thus obtained can have a porosity of 20-60% as a whole despite the mutually and partly strong combination of the fine powder. The product X is then impregnated with an aqueous or oily ink for stamping and printing.

Description

[Detailed description of the invention] The present invention relates to printed materials.

A feature of the present invention is that the printed portion is made of a sintered body of metal or inorganic material.

The printed body of conventional seals was often made of wood, stone, ivory, rubber, synthetic resin, etc. In addition, recently, stamps with a printed body that has countless fine continuous pores have become popular and are widely used, but in order to eliminate this drawback, the printed body lacks strength. Although it has been proposed to manufacture printed materials using hard materials such as metal,
It had not yet reached the stage of practical application.

Therefore, the present invention has been developed to produce typewriter typefaces, postmarks, etc. using fine powder of hard metal or inorganic material, and to make stamps that can be stamped with ink impregnated inside. Its purpose is to provide fonts.

An embodiment of the present invention will be described in detail below.

First, the material used for the printed body of the present invention is fine particles of stirrup material or fine particles of metal, and examples thereof are as follows.

Table 1 Next, a method for manufacturing a printed body using the fine powder materials listed in Table 1 will be described.

First, select any one of the materials listed in Table 1,
The appropriate amount of letters, etc. to be formed are placed in a mold with four parts or raised steps.

The material for the mold may be iron, lead, phenol photosensitive resin plate, etc., but aluminum is the most preferable material.

Further, the shape of the mold differs depending on the shape of the product to be molded. For example, if it is a flat plate type product, it is better to use a mold that expands in the upper F direction, and if you are trying to mold a roll type product, it is better to use a mold that expands by dividing it into left and right sides. Next, the material placed in the mold is moderately pressed to increase the density of the fine powder material.

Next, this material fine powder is temporarily solidified with a binder.

The reason for solidification is to temporarily retain the shape of the material fine powder itself and prevent it from deforming (to facilitate mold release and movement).

The material used as the binder is a thermoplastic resin, water-soluble resin, glue, or popal, which is applied to the surface.

If the temporary solidification with the above binder is incomplete, you can solidify by adding phenol, melamine, etc., or pouring water-based glue together.

Once solidified in this manner, it is dried and released from the mold.

Next, this is put into a sintering furnace and sintered.

Sintering temperature varies depending on the material used, but is 1.000℃
~4,000°C.

In addition, in order to make the printing surface uniform and to make the stamp clear, it is preferable to apply a press again after sintering with a pressure of 201 Di/d to 30 and 9/d.

Although the product thus produced or the fine powder material is partially firmly bonded to each other, voids are formed in the range of about 10 to 40% overall.

This is impregnated with water-based or oil-based ink and used for stamping.

Next, a case in which a typewriter typeface is formed using fine powder of stainless steel will be specifically described.

[Example 1] Put an appropriate amount of stainless steel (SUS 316) fine powder with a particle size of 100A into a flat mold made of aluminum together with water-based glue.The flat mold is vibrated to form the fine powder at the bottom of the flat mold. Spread it throughout the entire part of the Roman alphabet [A].

Next, the entire fine powder is pressed into a mold from above.

Continuing τ, this flat mold is placed in a drying chamber at a room temperature of 40° C. and left to dry and temporarily solidify.

Once dry, the fine powder mass is released from the mold, placed in a sintering furnace, and sintered at a temperature of approximately 2,000°C.

Sintering time is 10 minutes.

After sintering, it was removed from the sintering furnace and left to cool naturally.

In this state, the fine particles of stainless steel are partially welded together to form a solid solid mass, and as shown in Figure 1, 40% of the pores are formed inside. , a raised letter Y of the Roman alphabet (A) was formed on the surface.

When this typeface was impregnated with XK oil-based ink, attached to the tip of the platen of an English typewriter, and typed by striking it directly onto high-quality paper, clear prints were made on the high-quality paper.

If you stack two sheets of high-quality paper and put carbon paper between them and set it on a typewriter to print, the first sheet of high-quality paper on the front side will be directly printed with the ink impregnated in the type, and The carbon of the carbon paper was transferred to the second sheet of high-quality paper by the collision pressure of the type, and a clear print was made like the first sheet.

[Example 2] When the above typeface is attached to the print shaft of a check writer and printed on bill paper, the letter (A) in the Roman alphabet is engraved on the bill paper as in the case of conventional check writers, and at the same time the inside Printing was also done using ink impregnated with.

[Example 6] By the method described above, a printing roller Z having the letter Y protruding from its surface is formed (see Figure 2). When this is passed through a shaft rod and rolled in contact with the paper surface, there is no contact with the printing roller on the paper surface. At the same time that the same characters as the protruding characters were engraved, ink was also attached by the ink impregnated inside, resulting in a readable stamp 14J.

[Example 4] The type produced by the above method was stored in a bumpy stamping tool holder, and when the holder was held in hand and stamped on the paper surface, a clear stamp was made on the paper surface.

As described above, in the type body and roller according to the present invention, arbitrarily selected inorganic or metal fine powders are partially firmly bonded to each other, and voids of 10% to 60% can be formed inside. If this is impregnated with ink, the printing material will be strong and the ink can gradually leached in the printing direction, so it can be used for example, check writers, numbering, date stamps, typewriters, computers, calculators, etc. Not only is it useful as a font, but it is also useful as an inking roller, printing roller, or printing part of a bumpy hand stamp.
