From the labeling of the bottles to the box packing and case packing, there are many manual participation steps, the degree of automation is low, the labor cost is relatively high, and the packaging efficiency is easily affected by manual work. Summary of the Invention

[0004] The present invention provides a product labeling process to solve the technical problems of low automation degree and high labor cost in the labeling, packing, and case packing processes of products in the prior art.

[0005] To solve the above problems, a product labeling process provided by the present invention adopts the following technical solutions:

[0006] A product labeling process includes the following steps:

[0007] S1. Convey the bottles to the first side labeling station and paste a label on one of the sides of the bottle body;

[0008] S2. Convey the bottles to the first side label inspection station, and the bottles with unqualified first side labels are automatically removed;

[0009] S3. The bottles with qualified first-side labels are conveyed forward to the turning station, where the bottles are turned.

[0010] S4. The turned bottles are conveyed to the top labeling station, where labels are pasted on the tops of the bottles.

[0011] S5. The bottles are conveyed to the top label inspection station, and the bottles with unqualified top labels are automatically removed.

[0012] S6. The bottles with qualified top labels are conveyed to the second-side labeling station, where labels are pasted on the other side of the bottle body.

[0013] S7. The bottles are conveyed to the second-side label inspection station, and the bottles with unqualified second-side labels are automatically removed.

[0014] S8. The bottles with qualified second-side labels are conveyed to the cradling station. Meanwhile, the bottle cradles are conveyed to the cradling station by the bottle cradle conveyor line, and in-place detection is performed on the bottle cradles on the bottle cradle conveyor line. After the in-place detection of the bottle cradles is successful, the bottle-in-cradle manipulator grabs the bottles with qualified second-side labels and loads them into the bottle cradles.

[0015] S9. The bottle cradles with bottles are conveyed forward to the instruction sheet cradling station. Meanwhile, the instruction sheets are conveyed to the instruction sheet cradling station by the instruction sheet conveyor line, and in-place detection is performed on the instruction sheets. After the in-place detection of the instruction sheets is successful, the instruction sheet-in-cradle manipulator takes one instruction sheet and places it into the instruction sheet placement slot in the bottle cradle with the bottle.

[0016] S10. The bottle cradles with the placed instruction sheets are conveyed forward to the boxing station. Meanwhile, the cartons are conveyed to the boxing station on the carton conveyor line, and the boxing manipulator grabs the bottle cradles with the bottles and the instruction sheets and places them into the cartons.

[0017] S11. The cartons with the bottles, bottle cradles, and instruction sheets are conveyed to the product information card inserting station. The information card printer prints out the product information cards, and after the product information cards are detected in place, they are inserted into the cartons.

[0018] S12. The cartons with the inserted product information cards are conveyed to the box-closing station, where the side plates, top covers, and tongue plates at the top of the cartons are folded to close the cartons. Then, box-closing detection is performed, and the cartons with unqualified box-closing are automatically removed.

[0019] S13. The cartons with qualified box-closing are conveyed to the weighing station, where the cartons are weighed, and the cartons with unqualified weights are automatically removed.

[0020] S14. The cartons with qualified weights are conveyed to the carton labeling station, where labels are pasted on two corners and the sealing part of the cartons in sequence, and carton labeling detection is performed. The cartons with unqualified labeling are automatically removed.

[0021] S15. The carton is conveyed to the carton arranging station, and the carton pushing assembly pushes multiple cartons onto the carton arranging platform and arranges them into a layer of cartons in a square shape.

[0022] S16. The framing manipulator grabs a layer of cartons arranged in a square shape and places them into the transfer frame at the framing station. After the transfer frame is filled with cartons, it leaves the framing station.

[0023] The beneficial effects of the above technical solution are as follows: The labeling process of this product realizes the full automation of the whole process of labeling, palletizing, boxing, sealing, box labeling and final packing of bottled products, and can reject bottles with unqualified labeling or cartons with unqualified labeling to ensure the quality of labeling. At the same time, this process realizes the automatic packing of accessories such as instruction manuals, improves work efficiency, and can effectively save labor costs.

[0024] Further, in step S4, the bottle is conveyed to the top labeling station. After the bottle arrival detection photoelectric eye detects the bottle, the positioning cylinder clamps the bottle. At the same time, the top label printer prints a label, and the top labeling manipulator adsorbs the label and pastes it on the top of the bottle.

[0025] The beneficial effects of the above technical solution are as follows: After the positioning cylinder clamps the bottle, labeling is carried out, avoiding inaccurate label placement caused by the movement of the bottle during the labeling process.

[0026] Further, in step S6, the bottle is conveyed to the second side labeling station. After the bottle arrival detection photoelectric eye detects the bottle, the positioning cylinder clamps the bottle. At the same time, the second side label printer prints a label, and the second side labeling manipulator adsorbs the label and pastes it on the other side of the bottle body.

[0027] Further, in step S8, the bottle tray is conveyed to the end of the bottle tray conveying line. The bottle tray arrival detection photoelectric eye conducts in-place detection on the bottle tray. The bottle tray transfer assembly transfers the bottle tray at the end of the bottle tray conveying line to the bottle-in-tray conveying line on the main conveying line. The bottle-in-tray manipulator grabs the bottle with qualified second side label detection and places the bottle into the bottle tray on the bottle-in-tray conveying line. After the bottle tray is filled with bottles, the bottle tray and the bottles are conveyed to below the bottle pressing cylinder. After the bottle pressing photoelectric eye detects the bottle, the bottle pressing cylinder presses down on the bottle to tightly press the bottle in the bottle tray.

[0028] The beneficial effects of the above technical solution are as follows: After the bottle is placed in the bottle tray, the bottle pressing cylinder is used to tightly press the bottle in the bottle tray, and the bottle is firmly installed in the bottle tray, preventing the bottle from shaking during subsequent transportation.

[0029] Furthermore, in step S10, the carton is conveyed by the carton conveyor line to the cartoning station, the carton opening and transfer assembly opens the carton at the end of the carton conveyor line and transfers it to the cartoning conveyor line on the main conveyor line, the opening block rod on the cartoning conveyor line opens the top cover of the carton, and then the cartoning robot grabs the bottle tray containing the bottle and instruction manual on the bottle tray conveyor line and puts it into the carton on the cartoning conveyor line.

[0030] The beneficial effects of the above technical solution are: the carton opening and transfer component opens the carton at the end of the carton conveyor line and transfers it to the carton loading conveyor line, realizing the two steps of opening and transferring the carton, and the box opening baffle bar opens the top cover of the carton on the carton loading conveyor line, making it convenient to place bottles and bottle trays in the carton.

[0031] Furthermore, in step S11, the paper box is conveyed from the cartoning conveyor line to the product information card delivery station, the information card printer prints out the product information card, the product information card falls onto the information card conveyor belt at the exit of the information card printer, the information card detection electric eye detects the position of the product information card, the folding mechanism on the information card conveyor belt folds the product information card, and the folded product information card is conveyed to the end of the information card conveyor belt and falls into the paper box on the cartoning conveyor line.

[0032] The beneficial effects of the above technical solution are: the product information card is directly put into the paper box by the information card conveyor belt, the putting method is simple, the product information card is put into the paper box after being folded, and the area of the product information card is reduced after folding, which is convenient for putting.

[0033] Further, in step S12, the carton is conveyed to the box closing station after the product information card is loaded on the carton conveyor line, a fixed pressure plate presses down a side panel on the top of the carton, the carton is conveyed forward, and the side plate folding cylinder pushes downward the other side panel on the top of the carton. After completion, the carton continues to be conveyed forward, the top cover folding cylinder pushes downward the top cover of the carton, and the tongue folding plate cylinder pushes the tongue plate at the end of the folding top cover. After that, the carton is conveyed forward again, the correction cylinder corrects the position of the carton, and the tongue pressing cylinder presses the tongue plate into the carton. After completion, the carton continues to be conveyed forward, and the cover pressing cylinder presses down the top cover of the carton to complete the box closing.

[0034] The beneficial effect of the above technical solution is that after the tongue plate is inserted into the paper box, the top cover of the paper box is pressed down by the cover pressing cylinder, so that the paper box is closed more smoothly.

[0035] Furthermore, in step S16, before the framing robot grabs the carton and puts it into the transfer frame, the transfer frame is transported to the framing station via conveyor rollers. After the transfer frame detection electric eye detects that there is a transfer frame placed at the framing station, it sends a signal to the PLC control module. The PLC control module controls the framing robot to grab a layer of carton on the box sorting platform and put it into the transfer frame.

[0036] The beneficial effects of the above technical solution are as follows: After the detection photoelectric eye detects that the transfer frame is located at the box loading station, the box loading manipulator is controlled to grab the paper box and load it into the transfer frame, ensuring that there is a transfer frame at the box loading station during box loading. At the same time, when the transfer frame is used up, the frame can be replenished in a timely manner according to the situation. Description of the Drawings
