Description

Technical Field

[0001] This utility model belongs to the field of label pasting technology, specifically an automatic bottle labeling machine. Background Technology

[0002] Labeling machines are devices used to affix labels to bottles, primarily used in the food, pharmaceutical, and daily chemical industries. Existing round bottle labeling machines mainly consist of an unwinding reel, a buffer reel, a guide roller, a drive roller, a rewinding reel, a peeling plate, and a labeling roller. However, they cannot identify damaged bottles during labeling, resulting in labeling waste.

[0003] The relevant reference CN113002910A discloses an automatic bottle labeling machine, which includes a frame, a conveyor belt, a top pressure belt, a label-applying assembly, and a label-feeding assembly for feeding labels to the label-applying assembly. The conveyor belt, top pressure belt, label-applying assembly, and label-feeding assembly are all installed on the frame. The bottle is placed on the conveyor belt for conveying. The top pressure belt is located above the conveyor belt and presses against the top of the bottle. The top pressure belt and the conveyor belt have the same running speed and the same running direction. There are two sets of label-applying assemblies, which are located on both sides of the conveyor belt. Each label-applying assembly includes a power roller with a surface that can adsorb labels, and the two sets of power rollers rotate in opposite directions. The label-feeding assembly is located next to the power roller and feeds the label to the power roller. The structure is relatively complex. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic bottle labeling machine that avoids labeling waste, simplifies the structure, and reduces manufacturing costs.

[0005] To solve the above technical problems, this utility model provides an automatic bottle labeling machine, including an unwinding reel, a labeling reel, a guide reel, a take-up reel, and a conveyor belt; the conveyor belt is mounted on a conveyor belt frame; a guardrail I, a guardrail II, and a labeling seat are provided on the conveyor belt frame; the labeling seat is mounted on the conveyor belt frame on the side of guardrail I; the unwinding reel, labeling reel, guide reel, and take-up reel are mounted on the labeling seat; guardrail I and guardrail II are located on opposite sides of the conveyor belt; a peeling plate is provided between the unwinding reel and the labeling reel, and the peeling plate is mounted on the labeling seat; a pressing sponge is provided on the labeling reel; a mounting plate is provided on one side of the labeling reel, and the mounting plate is fixed between guardrail I and the conveyor belt frame; a photoelectric sensor is provided on the mounting plate, and a rejection structure is provided between the photoelectric sensor and the labeling seat, and the rejection structure is mounted on guardrail I and the conveyor belt frame.

[0006] By adopting the above technical solution, bottles are detected by photoelectric sensors on one side of the labeling roller. Sorting is achieved based on differences in photoelectric sensitivity. Signals are sent to a computer for processing to identify whether the bottles are damaged. This works effectively with the rejection structure, allowing qualified bottles to pass through and rejecting unqualified bottles, thus avoiding labeling waste. A peeling plate is fixed to the labeling base, and a photoelectric sensor is installed on the mounting plate. The mounting plate is fixed between guardrail I and the conveyor belt frame. Rejection structures are installed on guardrail I and the conveyor belt frame, simplifying the labeling machine structure and reducing manufacturing costs.

[0007] Preferably, the rejection structure includes a frame-shaped bracket, which is set on the guardrail I and the conveyor belt frame; a telescopic cylinder is installed on the bracket, a rotary motor is installed on the telescopic rod of the telescopic cylinder, and a gripper is installed on the output shaft of the rotary motor, the gripper being shaped to fit the bottle.

[0008] By adopting the above technical solution, when the photoelectric sensor detects a damaged bottle, the telescopic cylinder extends its gripper to hold the defective bottle, the rotary motor rotates to tilt the bottle down, and the telescopic cylinder extends again to send the defective bottle out through the gap between the protective barrier II and the conveyor belt frame. Through the coordinated operation of the telescopic cylinder, rotary motor, and gripper, the defective bottles are accurately and efficiently rejected, avoiding the need to label them, improving labeling efficiency, and enhancing product quality.

[0009] Preferably, the bracket is installed on the guardrail I and the conveyor belt frame by fasteners.

[0010] By adopting the above technical solution, the bracket uses the guardrail I and the conveyor belt frame as the installation base, eliminating the need for additional complex installation structures, simplifying the installation process, and reducing installation costs.

[0011] Preferably, the upper surface of the conveyor belt frame is flush with the upper surface of the conveyor belt.

[0012] By adopting the above technical solution, the surfaces of the conveyor frame and the conveyor belt are flush, which makes it easier to push unqualified bottles into the waste box.

[0013] Preferably, the peeling plate is 30-80mm long and 0.5-3mm thick, has sharp edges, and is tilted at 30 degrees to the label surface.

[0014] By adopting the above technical solution, the label can be more easily separated from the backing paper.

[0015] Preferably, the tail of the peeling plate is chamfered; the tail of the peeling plate is 1-3mm away from the labeling wheel.

[0016] By adopting the above technical solution, the chamfer at the tail of the peeling plate forms a smooth transition surface. The distance between the transition surface and the labeling roller is 1-3 mm, which helps the label maintain the correct movement trajectory after peeling. After being peeled, the label is quickly pasted onto the bottle body by the labeling roller, making the label adhere to the bottle body more smoothly after the backing paper is peeled off, thus improving the reliability of the equipment.

[0017] Preferably, the take-up roller is driven by a servo motor, which is mounted on the bottom surface of the label holder, and the output shaft of the servo motor passes through the label holder and is keyed to the take-up roller.

[0018] By adopting the above technical solution, the servo motor is installed on the bottom surface of the labeling seat and directly connected to the winding wheel. The connection method is relatively simple. When maintenance or replacement is required, operators can easily disassemble and install the servo motor, which shortens the maintenance and replacement time and reduces maintenance costs.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a photoelectric sensor on one side of the labeling wheel to detect bottles, and sorts them by the difference in photoelectric sensitivity. The signal is sent to a computer for processing to identify whether the bottle is damaged. It works effectively with the rejection structure to release qualified bottles and reject unqualified bottles, thus avoiding labeling waste.

[0020] 2. The overall structure of this utility model is compact and simple. The peeling plate is fixed on the labeling seat, and a photoelectric sensor is set on the mounting plate. The mounting plate is fixed between the guardrail I and the conveyor belt frame. The guardrail I and the conveyor belt frame are equipped with a rejection structure, which simplifies the structure of the labeling machine and reduces manufacturing costs.

[0021] 3. The frame-shaped bracket of this utility model utilizes the guardrail I and the conveyor belt frame as the installation base, eliminating the need for additional complex installation structures, simplifying the installation process, and reducing installation costs. A waste bin is installed on the side of the guardrail II for easy collection of rejected defective bottles and for convenient cleaning by operators. Attached Figure Description

[0024] like Figure 1 As shown, an automatic bottle labeling machine includes an unwinding reel 1, a labeling reel 2, a guide reel 21, a take-up reel 3, and a conveyor belt 4. The conveyor belt 4 is mounted on a conveyor belt frame 5. A protective barrier I 6, a protective barrier II 7, and a labeling seat 8 are provided on the conveyor belt frame 5. The labeling seat 8 is mounted on the conveyor belt frame 5 on the side of the protective barrier I 6. The unwinding reel 1, the labeling reel 2, the guide reel 21, and the take-up reel 3 are mounted on the labeling seat 8. The protective barriers I 6 and II 7 are located on both sides of the conveyor belt 4, respectively. Figure 2 As shown, a peeling plate 9 is installed between the unwinding roller 1 and the labeling roller 2. The peeling plate 9 is fixedly installed on the labeling seat 8 via a vertical plate 22. A pressing sponge 20 is installed on the labeling roller 2 to press the label firmly under the action of the sponge. A mounting plate 10 is installed on one side of the labeling roller 2, and the mounting plate 10 is fixed between the guardrail I 6 and the conveyor belt frame 5. Figure 4 As shown, a photoelectric sensor 11 is installed on the mounting plate 10, and a rejection structure 12 is installed between the photoelectric sensor 11 and the labeling seat 8. The rejection structure 12 is installed on the guardrail I 6 and the conveyor belt frame 5. This application uses the photoelectric sensor 11 on one side of the labeling wheel 2 to detect bottles, achieving sorting through differences in photoelectric sensitivity. Signals are sent to a computer for processing to identify whether the bottles are damaged. This works effectively with the rejection structure, allowing qualified bottles to pass and rejecting unqualified bottles, avoiding labeling waste. This application fixes the peeling plate 9 to the labeling seat 8, and the mounting plate 10 is fixed between the guardrail I 6 and the conveyor belt frame 5. The rejection structure 12 is installed on the guardrail I 6 and the conveyor belt frame 5, simplifying the labeling machine structure and reducing manufacturing costs. A waste box 17 is installed on the side of the guardrail II 7 to facilitate the collection of rejected unqualified bottles and to facilitate cleaning by operators.

[0025] like Figure 3As shown, the peeling plate 9 is 30-80mm long and 0.5-3mm thick. The peeling plate 9 has a sharp edge 18 and is inclined at a 30-degree angle to the label surface, making it easier to separate the label from the backing paper. The tail of the peeling plate 9 is chamfered; the distance between the tail of the peeling plate 9 and the labeling roller 2 is 1-3mm. The chamfer at the tail of the peeling plate 9 forms a smooth transition surface, and the distance between the transition surface and the labeling roller 2 is 1-3mm, which helps the label maintain the correct movement trajectory after peeling. After being peeled, the label is quickly adhered to the bottle body by the labeling roller 2, allowing the label to adhere more smoothly to the bottle body after peeling off the backing paper, improving the reliability of the equipment.

[0026] like Figure 5 As shown, the rejection structure 12 includes a frame-shaped bracket 13, which is mounted on the guardrail I 6 and the conveyor belt frame 5. A telescopic cylinder 14 is installed on the bracket 13, and a rotary motor 15 is mounted on the telescopic rod of the telescopic cylinder 14. A gripper 16 is mounted on the output shaft of the rotary motor 15, and the gripper 16 is shaped to fit snugly against the bottle. When a photoelectric sensor detects a damaged bottle, it sends a signal, the telescopic cylinder 14 extends the gripper 16 to hold the defective bottle, the rotary motor 15 rotates to tilt the bottle down, and the telescopic cylinder 14 extends again to send the defective bottle out through the gap between the guardrail II 7 and the conveyor belt frame 5. Through the coordinated operation of the telescopic cylinder, the rotary motor, and the gripper, precise and efficient rejection of defective bottles is achieved, avoiding the need to label defective bottles, improving labeling efficiency, and enhancing product quality.

[0027] The bracket 13 is installed on the guardrail I 6 and the conveyor belt frame 5 by fasteners 23, and a waste box 17 is set on the side of the guardrail II 7. The bracket 13 uses the guardrail I 6 and the conveyor belt frame 5 as the installation base, which eliminates the need for additional complex installation structures, simplifies the installation process, and reduces installation costs.

[0028] The upper surface of the conveyor frame 5 is flush with the upper surface of the conveyor belt 4. The flush surfaces of the conveyor frame 5 and the conveyor belt 4 facilitate the pushing of defective bottles into the waste box 17.

[0029] The take-up reel 3 is driven by a servo motor 19, which is mounted on the bottom surface of the label holder 8. The output shaft of the servo motor 19 passes through the label holder 8 and is keyed to the take-up reel 3. The servo motor 19 is mounted on the bottom surface of the label holder 8 and directly connected to the take-up reel 3, making the connection relatively simple. When maintenance or replacement is required, operators can easily disassemble and install the servo motor 19. Compared to motors installed inside equipment or in hard-to-reach locations, this structure significantly shortens maintenance and replacement time and reduces maintenance costs.

[0030] The photoelectric sensor 11, telescopic cylinder 14, rotary motor 15, and computer in this application are connected via signal lines. During labeling, the label paper is released from the unwinding wheel 1 and transported by two guide wheels 21, while the backing paper is wound up by the rewinding wheel 3. Bottles are conveyed forward on the conveyor belt 4, with gaps between each pair of bottles. The photoelectric sensor 11 detects each passing bottle, sorts them based on differences in photoelectric sensitivity, and sends a signal to the computer for processing to identify whether the bottle is damaged. If damaged, the computer outputs a signal to drive the telescopic cylinder 14 to extend its gripper 16 to hold the defective bottle, drives the rotary motor 15 to tilt the bottle, and then drives the telescopic cylinder 14 to send the defective bottle out through the gap between the guardrail II 7 and the conveyor belt frame 5. The telescopic cylinder, rotary motor, and gripper work together to accurately and efficiently remove defective bottles, preventing them from entering the labeling process, avoiding labeling waste, and improving labeling efficiency. Once the bottles pass inspection, the sharp edge 18 of the peeling plate 9 peels one end of the label from the backing paper onto the bottle. Then, the sponge 20 on the labeling roller 2 presses the label firmly against the label surface, evenly pressing the label onto the bottle. After labeling, the bottles are conveyed to the next work module by the conveyor belt 4.

[0031] The unwinding roller 1, labeling roller 2, rewinding roller 3, and peeling plate 9 are mounted on a labeling seat 8, which is mounted on a conveyor belt frame 5 on the side of the guardrail I 6. A photoelectric sensor 11 is fixed between the guardrail I 6 and the conveyor belt frame 5 via a mounting plate 10. A rejection structure 12, including a telescopic cylinder 14, a rotary motor 15, and grippers 16, is mounted on the guardrail I 6 and the conveyor belt frame 5. The overall structure is relatively simple, reducing manufacturing costs.
