Description
Technical Field
[0001] The utility model relates to the technical field of ceramic tile production, in particular to a production line for spraying invisible codes on the surface of ceramic tiles. Background Art
[0002] In order to achieve orderly sales in the market, the common practice of each ceramic production enterprise is to spray information on the packaging of each package of products: company name, place of origin, batch number, production date, etc. Information, and then through the sales software, it can be queried where this product is sold. However, since there is no anti-counterfeiting code on each tile in this conventional mode, it cannot solve the problem that customers sell the products privately to other areas by removing the packaging or replacing the packaging, resulting in market chaos. When the ceramic tile is laid on the ground, even if the enterprise inspection personnel are on the spot, it is impossible to determine where this tile was bought from, which is very disadvantageous for combating cross-region sales. In order to be able to track where each ceramic tile is sold, and to solve the problem that even if the user lays the tile on the ground, the product information can also be read through a special device. Therefore, during the production process of ceramic tiles, invisible codes are usually sprayed on the front of the ceramic tiles for easy traceability.
[0003] However, due to the particularity of the invisible code, it can only be read by a special code reading device. When reading, there are strict requirements for the position and distance between the code reader and the ceramic tile, and the ceramic tile must be in a static state to ensure the recognition accuracy rate. Therefore, simply spraying invisible codes on the tile surface makes it difficult to directly read the invisible code when the green body is automatically packed. Summary of the Utility Model

[0023] In an embodiment of the present utility model, such as Figure 1-2As shown in the figure, a production line for spraying invisible codes on the surface of tiles includes a press 1, a tile turner 2, a dryer 3, an inkjet printer 4, a firing kiln 5, a packing device 6, a bottom code spraying device 81, a first bottom code reading device 82, an invisible code spraying device 83, a second bottom code reading device 84, a side code spraying device 85, a side code reading device 86, and a conveyor line 9. The press 1, the tile turner 2, the dryer 3, the inkjet printer 4, the firing kiln 5, and the packing device 6 are arranged in sequence along the conveying direction of the conveyor line 9. The press 1 is used to press a brick blank into a tile, and the conveyor line 9 is used to convey the tiles. The bottom code spraying device 81 is arranged between the press 1 and the tile turner 2, and the bottom code spraying device 81 is used to spray a two-dimensional code on the back of the tile. The tile turner 2 is used to turn over the tile with the bottom code sprayed. The dryer 3 is used to dry the turned-over tile. The first bottom code reading device 82 and the invisible code spraying device 83 are arranged between the dryer 3 and the inkjet printer 4. The first bottom code reading device 82 is connected to the invisible code spraying device 83. The first bottom code reading device 82 is used to read the bottom code of the dried tile and feed back the read information to the invisible code spraying device 83. The invisible code spraying device 83 is used to receive the information from the first bottom code reading device 82 and spray an invisible code on the front of the tile. The inkjet printer 4 is used to inkjet the tile surface with the invisible code sprayed. The firing kiln 5 is used to fire the inkjeted tile. The second bottom code reading device 84, the side code spraying device 85, and the side code reading device 86 are arranged between the firing kiln 5 and the packing device 6. The second bottom code reading device 84 is connected to the side code spraying device 85.

The side code spraying device 85 is used to receive the information from the second bottom code reading device 84 and spray a two-dimensional code on the side of the tile. The side code reading device 86 is used to read the two-dimensional code on the side of the tile.In this embodiment, the press 1, the tile turning device 2, the dryer 3, the inkjet printer 4, the firing kiln 5, the packing equipment 6, the bottom code inkjet coding equipment 81, the first bottom code reading equipment 82, the invisible code inkjet coding equipment 83, the second bottom code reading equipment 84, the side code inkjet coding equipment 85, the side code reading equipment 86 and the conveyor line 9 are all prior arts. The first bottom code reading equipment 82, the invisible code inkjet coding equipment 83, the second bottom code reading equipment 84, the side code inkjet coding equipment 85 and the side code reading equipment 86 are respectively connected to the warehousing and sales system. During operation, the press 1 stamps the green body into a ceramic tile. At this time, the back of the ceramic tile faces up and the front of the ceramic tile faces down. Then the conveyor line 9 conveys the ceramic tile to the bottom code inkjet coding equipment 81. The bottom code inkjet coding equipment 81 sprays a two-dimensional code on the back of the ceramic tile to form a bottom code, and uploads the coding information to the warehousing and sales system. After spraying the bottom code, the conveyor line 9 conveys the ceramic tile to the tile turning device 2. The tile turning device 2 turns the ceramic tile by 180°, so that the front of the ceramic tile faces up and the back of the ceramic tile faces down. After the turning is completed, the conveyor line 9 conveys the ceramic tile to the dryer 3. After the ceramic tile is dried, the conveyor line 9 conveys the ceramic tile to the first bottom code reading equipment 82. The first bottom code reading equipment 82 reads the bottom code of the ceramic tile, obtains the corresponding information and feeds it back to the invisible code inkjet coding equipment 83. Then the invisible code inkjet coding equipment 83 generates a corresponding invisible code according to the fed-back information and sprays the invisible code on the front of the ceramic tile. The reading information of the bottom code and the coding information of the invisible code are correspondingly uploaded to the warehousing and sales system. After spraying the invisible code, the conveyor line 9 conveys the ceramic tile to the inkjet printer 4. The inkjet printer 4 applies decorative patterns on the front of the ceramic tile. Specifically, the decorative patterns cover the invisible code. Then the conveyor line 9 conveys the ceramic tile into the firing kiln 5 for firing. After firing, the conveyor line 9 conveys the ceramic tile to the second bottom code reading equipment 84. The second bottom code reading equipment 84 reads the bottom code and feeds back the information to the side code inkjet coding equipment 85. The side code inkjet coding equipment 85 generates a corresponding side code according to the fed-back information and sprays a two-dimensional code on the side of the ceramic tile to form a side code. Then the conveyor line 9 conveys the ceramic tile in the direction of the packing equipment 6. Before being conveyed to the packing equipment 6, it also needs to go through the information reading and uploading of the side code reading equipment 86. The side code reading equipment 86 reads the side code, reads out and associates the information of the corresponding bottom code and invisible code, and then uploads it to the warehousing and sales system. Through the press 1, the tile turning device 2, the dryer 3, the inkjet printer 4, the firing kiln 5, the packing equipment 6, the bottom code inkjet coding equipment 81, the first bottom code reading equipment 82, the invisible code inkjet coding equipment 83, the second bottom code reading equipment 84, the side code inkjet coding equipment 85, the side code reading equipment 86 and the conveyor line 9, by spraying the bottom code, invisible code and side code during the production process of the ceramic tile, the association of the bottom code, invisible code and side code is realized, and it is easy to read the information of the invisible code into the computer on the production line and associate it with the warehousing and sales system, so as to achieve the purpose of traceability of each ceramic tile.
[0024] As Figure 1-2 shown, it further includes a polishing and edging device 7, which is used to polish and grind the fired tiles. The polishing and edging device 7 is arranged between the firing kiln 5 and the packing device 6. In this embodiment, the polishing and edging device 7 is a prior art. After the firing kiln 5, polishing and grinding are carried out. In terms of aesthetics, the edges of the tiles after polishing and edging become smooth, bright, without burrs, and the whole looks cleaner and more beautiful; in terms of tile splicing, the edging treatment can make the joints more natural; in terms of practicality, the edge treatment helps to prevent moisture from seeping in from the edges of the tiles, enhancing the waterproof performance of the tiles. The smooth tile edges reduce the risk of scratching or hurting people during daily use, which is particularly important for families with children or the elderly. The edges of the edging tiles are not easy to hide dirt and are more convenient to clean. The second bottom code reading device 84, the side code spraying device 85 and the side code reading device 86 are arranged between the polishing and edging device 7 and the packing device 6. After polishing and edging, the bottom code is read again and the side code is sprayed, and the side code is read before the packing device 6 to associate the bottom code, the invisible code and the side code for later traceability.
[0025] As Figure 1-2 shown, it further includes a grading device 8, which is used to screen and grade the polished and ground tiles. The grading device 8 is arranged between the polishing and edging device 7 and the packing device 6, and the second bottom code reading device 84 and the side code spraying device 85 are arranged between the polishing and edging device 7 and the packing device 6, and the side code reading device 86 is arranged between the grading device 8 and the packing device 6. In this embodiment, the grading device 8 is a prior art. After passing through polishing and grinding, secondary bottom code reading and side code spraying in sequence, the grading device 8 grades and screens the tiles. Grading is to further ensure that the quality of the tiles meets the established standards and requirements. After firing and polishing and grinding, although most tiles have reached the basic production requirements, there may still be some minor defects or quality problems, such as size deviation, uneven gloss, surface scratches, etc. Through grading, these unqualified products can be found and removed in time to ensure that the tiles leaving the factory are of high quality.
[0026] As Figure 1-2 shown, the numbers of the packing device 6 and the side code reading device 86 are both two. In this embodiment, the two packing devices 8 are connected in parallel to the output end of the grading device 8. After the grading and screening by the grading device 8, the side code is read to associate the bottom code and the invisible code and then corresponding packing is carried out, so that the tiles can be classified and managed according to different quality grades, which is convenient for subsequent sales and use.
[0027] As Figure 1-2As shown, it further includes a warehousing device 10, and the warehousing device 10 is arranged at the output end of the packing device 6. In this embodiment, the warehousing device 10 is a prior art. The output ends of the two packing devices 6 are both connected to the warehousing device 10. Immediately warehousing after the two packing devices 6 finish packing can not only avoid material accumulation, but also facilitate the classified materials to be placed in different areas.
[0028] As Figure 1-2 shown, the numbers of the press 1, the bottom code spraying device 81, and the tile turning device 2 are three respectively. The output ends of the three tile turning devices 2 are respectively connected to the dryer 3. In this embodiment, the output ends of the three presses 1 are respectively connected to the three tile turning devices 2, and the output ends of the three tile turning devices 2 are respectively connected to the dryer 3. The bottom code spraying device 81 is arranged between each press 1 and the tile turning device 2. The three presses 1 can produce corresponding tiles according to requirements, which is beneficial to improving production efficiency.
