Description

Identifying Object For Heat Treated Products

The present invention relates to a recognition indicator of a product for sintering, and more particularly, to a recognition indicator that can be directly molded into a product manufactured by passing through a high temperature firing furnace or a product subjected to high temperature indirect heat in the manufacturing process.

Conventionally, a technology for attaching adhesive label sheets and utilizing them as a display method for recognition that a product passing through a high-temperature firing furnace or an electric furnace in a manufacturing process such as ceramics, an electromagnetic plate, a cathode ray tube, and the like can withstand high temperatures is mainly used. As the prior art of such a label sheet for baking, US Patent No. 4,775,786, US Patent No. 4,971,858, EPO 649126A1 and the like are known.

Among them, U.S. Patent No. 4,775,786 discloses a bar code label based on ceramics. Such materials are prone to cracking during drying and lack of flexibility, resulting in long drying times and high manufacturing costs. have.

In addition, in the case of US Patent No. 4,971,858, a sheet for forming a pattern and a method of manufacturing the same are known. The ink receiving layer of the sheet contains glass frit in addition to metal powder, metal oxide powder, and an organic binder. The glass frit may adhere to the adherend, or the barcode may be damaged due to bubbles generated by the glass frit, and the manufacturing process of the label may be complicated and uneconomical.

Furthermore, EPO649126A1 discloses a label comprising a film made of silicone resin, Inorganic Monocrystalline Fiber and adhesive, wherein the adhesive consists of silicone resin and metal powder, which also has high temperature stability or adhesion. It was not possible to obtain a desirable degree in the surface.

That is, the technique using the label sheet for baking including the above-described prior art, as shown in Figure 1 and Figure 2, the release paper layer 1, the adhesive layer (2), the ink receiving layer (3) and the pattern layer It has a combined configuration of (4), but due to the above-mentioned problems, these label sheets are exposed to a lot of disadvantages to be applied to a plastic product that is directly or indirectly heated while passing through a high temperature firing furnace, and the manufacturing process is exposed. There is a problem that the manufacturing cost increases due to the complicated and expensive raw materials.In case of using the automatic labeling device for labeling, it causes unbalance between the label sheets and the operation error of the automatic labeling device frequently. This is a reality in which work losses due to shutdowns occur frequently. Furthermore, due to the nature of the work that requires the use of expensive labels, maintenance of the auxiliary equipment of the production line is required, and the necessary consumables must be replaced frequently, which is a major factor that increases the manufacturing cost of the product along with the necessary manpower. have.

In addition, in the case of the glass panel used in the manufacture of the recent flat CRT, the side part to which the label should be attached exists only as much as its own thickness, so that the attachment work by the automatic labeling device is very difficult because the space on the label attachment part is not sufficiently secured. It causes a serious problem that a lot of adhesion failure occurs.

Therefore, the object of the present invention is to solve the above-mentioned conventional problems, but not directly using a label as in the prior art, but molded directly on the appropriate portion of the product for baking, for example, the existing labeling portion, even at high temperatures It is to provide a recognition indicator that can perform a recognition indicator function such as a barcode that is not damaged.

The present invention provides a recognition indicator formed by molding the recognition display directly on the upper surface of the appropriate portion of the product for baking, in order to achieve the above object, the recognition display is formed by using a heat-resistant ink or paint.

Further, a recognition display body is formed by previously forming a heat-resistant layer for forming a recognition display portion on an upper surface of an appropriate portion of a product for baking, and forming a recognition display portion on an upper surface of the heat-resistant layer.

In this case, the recognition display unit may be configured in any form that can be recognized as a barcode, numbers, letters, symbols, or a combination thereof, which is an ink jet printing method or a dot printing method (Dot). Molding by a machine such as a printing method of a printing method. Of course, in addition to such a device, if there are other methods capable of shaping the recognition mark, an appropriate method may be selected and molded.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail with reference to various preferred embodiments.

3 to 6 show a recognition display body of the present invention in which a recognition display portion 6 is directly molded on a product 5 for baking or a heat-resistant layer 7 is formed in advance, and a recognition display portion 6 is formed thereon. Shown in schematic form.

In addition, the recognition display unit 6 is formed in the form of a bar code, letters, numbers, symbols or a combination thereof that can be recognized by the scanner, as shown in Figure 4 to form the recognition display unit 6 of the sole type or As shown in FIG. 5, the heat resistant layer 7 may be first formed, and then the recognition display unit 6 may be formed on the upper surface of the heat resistant layer 7.

In this case, when the heat-resistant layer 7 is formed, it is preferable to use the heat-resistant layer 7 and the recognition display unit 6 so as to distinguish colors as mutual complementary colors. This is to use the heat-resistant layer 7 having a complementary color relationship. This is because the recognition display unit 6 can be exposed more clearly as a background, and the recognition by the scanner can be made more sure. Furthermore, in the case where the plastic product 5 is an achromatic material having an achromatic color, the surface display and recognition of the surface of the plastic product 5 is performed when the recognition display part 6 is also printed in the achromatic color system as shown in FIGS. 3 and 4. Since the color of the display unit 6 also maintains the same state, the color of the surface color of the plastic product 5 and the color of the recognition display unit 6 are not clearly distinguished from each other, making it difficult to recognize the scanner. This may cause an error in recognition of the scanner. Accordingly, as shown in FIGS. 5 and 6, when the heat-resistant layer 7 and the recognition display unit 6 are in a state where color separation can be clearly performed, for example, in a state of complementary color relationship, a recognition image of the scanner The occurrence of errors can be prevented.

Of course, if the surface color of the plastic product 5 and the color of the recognition display unit 6 can be clearly distinguished, even if the recognition display unit 6 is directly exposed to the surface of the plastic product 5 scanner Since there is no problem in the recognition of the present invention, even if the recognition display unit 6 is directly made in the form shown in Figs.

In the recognition display body of the present invention, in the case of the heat-resistant ink or paint used in the printing molding of the recognition display unit 6 or the heat-resistant layer 7, the firing temperature is higher than or equal to the firing temperature required for the baking product 5. What is necessary is just to select and utilize heat-resistant ink or paint which have heat-resistant temperature, for example, when baking temperature of 250 degreeC is requested | required, it is good to select and use heat-resistant ink or paint which meets the specification.

Next, a molding apparatus adopting and utilizing the above-described recognition indicator will be described with reference to FIGS. 7 to 9 with reference to a preferred example.

That is, as shown in Fig. 7, the apparatus 10 for forming the recognition display portion 6 on the upper surface of the appropriate portion of the product 5 for firing is installed on one side of the manufacturing line 20 to produce the manufacturing line 20 Recognition display unit 6 is sequentially made for each firing product (5) entered from one side of the), the head portion 12 of the device 10 coincides with the upper surface of the appropriate portion of the firing product (5) It may be installed to be located in a position to.

At this time, if necessary, as shown in FIG. 8, when the device 30, 40 is viewed based on the advancing direction of the product 5 for baking on the manufacturing line 20, a predetermined distance is spaced in the front and rear directions. The front device 30 may be used as a device for molding the heat resistant layer 7, and the rear device 40 may be configured to be used as a device for molding the recognition display unit 6. Maybe. Of course, at this time, if the heat-resistant ink or paint used in the heat-resistant layer 7 formed while passing through the front device 30 is not easily dried naturally between the front and rear devices 30, 40 The dryer 50 is installed so that the heat-resistant layer 7 printed from the front device 30 can be formed to recognize the display unit 6 in the rear device 40 while the dryer 50 is completely dried. It is preferable to.

In addition, in the case of the front device 30, as described above, the inkjet printing method or not mentioned separately, but is adopted by various coating methods such as coating method by roller, coating method by brush, coating method by spraying, etc. Although it is possible, for example, the heat-resistant heater layer 7 may be formed on the product 5 for baking by the form which combined the mechanism which supplies heat ink or paint, and the application mechanisms, such as a brush and a roller.

Thus, in the case where the recognition display unit 6 is formed by using the molding apparatus shown in FIG. 7, the apparatus of the plurality of plastic products 5 moving at regular intervals on the manufacturing line 20 without the heat-resistant layer 7 When the firing product 5 is placed in front of the front surface of the container 10, for example, the recognition display unit 6 is directly printed on the side surface of the firing product 5 and molded. The unit 12 is operated to print molding the recognition display unit 6 by the heat-resistant ink.
