BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention engraves an identification bar (article) code for displaying the information such as the origin and area of a product as an identification bar (article) code, which can confirm the orientation of the so-called identification bar (article) code. Related to materials or products.

2. Description of the Related Art Conventionally, wood, fibers, stones, glass, metals, synthetic resin materials, ceramics, etc. have typically been used as materials for products, and these materials have been commercialized. In order to indicate the manufacturer in these products, the manufacturer's own trade name, trademark, etc. are printed on a sticker, which is affixed to the product, or stamped on the plate by press processing, and this product is Attached to or engraved directly on the material. In this way, trade names, trademarks, etc. are applied using a printing machine, a mold, or a mold. In the recent printing technology, there is also a so-called etching process in which a printing ink is made into a chemical liquid that dissolves a resin or a metal and a desired character or design can be delicately applied to a product.

Further, the present invention may be an etching process by the above-mentioned printing, but particularly uses a laser device. The latter outlines a so-called laser device in the context of engraving identification bar codes on various materials or products while operating the laser device by making full use of data from a computer. Gas (CO ₂ ) is mainly used for laser equipment.
In addition to laser devices, there are yag laser devices, UV laser devices, excimer laser devices, and the like. In addition, it is effective to use a laser for processing when it is used in a narrow position because it has a high degree of focusing. In other words, since the energy can be concentrated on the spot, an extremely high temperature can be generated locally.

It can be used for contacts. In addition, there is a ruby laser in the solid laser processing machine, but the reflecting mirrors are placed opposite to each other on both ends of the ruby crystal, and one reflecting mirror completely reflects,
The other reflecting mirror can transmit a part of light through a mask. At this time, the Xe discharge tube excites the chromium electrons in the ruby crystal, and the generated light reciprocates between the two reflecting mirrors and causes a feedback action between the reciprocations, so that automatic emission occurs. In the method of radiating from the reflector, energy is small because the energy is small because it is stimulated to be emitted before the energy is sufficiently accumulated in the resonator, and the pulse cannot be lengthened. Giant pulse

As a so-called Q-switch method, a rotating prism or a saturable dye is placed between the ruby and the reflecting mirror so that resonance occurs at a predetermined position. When the laser beam is applied to the material or product, the desired concave groove is formed by the photoheat of the beam. Further, when the tip of the laser beam is moved in a desired direction, a glass (not shown) provided in the laser device and which can freely move back and forth and left and right is used. For example, a laser device (not shown) having a medium laser wavelength is used. This is a method of applying a laser beam and operating a glass (not shown) that moves forward, backward, leftward and rightward, and continuously moves the point light at the tip of the laser beam according to the identification data.

[0006]

When printing a trade name or a trademark on the surface of various materials or products, the adhesiveness of printing is poor depending on the material other than paper. Although the surface is subjected to a special process of applying varnish, for example, there is a drawback that the cost is high due to the large-scale equipment. Further, in the case of press working, there is a drawback that the cost of the die and the mold and the equipment cost for the marking become high. Moreover, since the mold is likely to be worn during long-term use, there is a drawback that the engraved machining line becomes unclear.
Further, when the product is extremely small or the position of the marking is narrow, there is a drawback that the trade name and the trademark cannot be processed. In addition, processed products of trademarks and trade names were thin parts like needles.

[0007] There is a drawback that pressing cannot be performed depending on the product which is not only thin or thin but also thin-walled, and small and concave or convex. There is also a drawback that small or thin parts cannot be marked with a stamped plate. In addition, there is a drawback that it takes time to attach or detach the mold and the mold. Further, printing plates, dies, and molds are greatly worn in mass production, so that they have a big defect in durability. When the mold and mold are removed and an identification bar (article) code for identifying a large amount of information is engraved by a laser beam of a laser device, each of the above-mentioned drawbacks is solved, but only the identification bar (article) code is eliminated. , Eg hand-sewn needles or other materials used for sewing

Alternatively, even if the product or the product is engraved and the material or product is destroyed, and the identification bar (article) code is present in the fragment,
The identification bar (article) code has the drawback that it cannot be confirmed at all whether it is upside down, that is, the vertical direction. In addition, it is important to identify the means to confirm the top and bottom of the identification bar (article) code other than the identification bar (article) code.
If this is not the case, there is a drawback that the data amount of the identification bar (article) code will be halved if the top and bottom are inverted in plan. That is, when the data 1211 is inverted to 1121, the data becomes the same as the data 1121 of the identification bar (article) code engraved on another sewing needle or product.

An object of the present invention is to determine the vertical direction of an identification bar (row) code engraved on a material or a product in order to eliminate such a defect.

[0010]

In order to achieve such an object, the present invention provides a material or product for engraving an identification bar (article) code, which is a product of metal and synthetic resin, glass, ceramics, stone, or rubber. Alternatively, one or a plurality of concave grooves that form a notch width in the material and one or more parallel to the concave groove that are adjacent to the concave groove and that form a flat width outside are arranged in parallel along the material or the product.
And alternately formed, the width of the cutout width of the recessed groove and the number of recessed grooves having the cutout width, and the width of the flat width of the thick portion and the number of thickened portions having the flat width, the product The identification bar (article) code is used to identify the source, manufacturing time, area, etc. of the groove, and the width of each of the notch width of the concave groove and the flat width of the thick portion becomes the identification bar (article) code. A wide and constant reference width is divided by a dividing groove, and this reference width is formed on either the left or right side of the identification bar (article) code,
The presence of this reference width determines the vertical direction of the identification bar (article) code engraved on the material or product.

A constant reference width C, which is larger than each width of the flat width 21 of the thick portion 20 to be the (bar) code B, is divided by the delimiter groove 30 so that the reference bar C on the right and left sides of the identification bar (bar) code B is separated. The reference width C, which is formed on one of the two sides, determines the vertical direction of the identification bar (row) cord B engraved on the hand-sewn needle body 1. To further explain, the laser beam (not shown)
Is directed in the longitudinal direction of the hand-sewn needle main body 1 and the dividing groove 30 is formed while applying the heat of light. Further, when moving the tip of the laser beam in a desired direction, a glass (not shown) provided in the laser device and which can freely move back and forth and left and right is used. Hand-sewn needle book

A laser beam is directly applied to the surface of the body 1, and the point light at the tip of the laser beam is continuously moved in accordance with the identification data as the glass (not shown) is moved back and forth and left and right. Also, a laser device having a medium laser wavelength is appropriately selected and used. The laser beam is engraved from a point light into a line. This laser beam is orthogonal to the longitudinal direction of the hand-sewn needle body 1 and reciprocates in parallel to engrave a desired interval. That is, the concave groove 10 and the dividing groove 30 are formed based on the data. At this time, in order to form the concave groove 10 and the dividing groove 30 on the surface of the plated layer, the heating close to the intermediate temperature is set to an appropriate temperature, and this adjustment is performed by the adjusting speed and the bite (not shown).

Adjustments in terms of heating are relatively easy as a lamp (not shown) allows adjustment of the light source. Therefore, other gas laser devices may be used depending on the depth of engraving. Also, since the laser device can be used by computer data, it is effective as a so-called hidden code for distinguishing small products and unauthorized similar products when it is desired to engrave small, and the large flat plate depends on the printing method. The barcode is etched by a solution that dissolves the material.
