Description
Technical Field
[0001] This utility model belongs to the field of labeling equipment technology, specifically relating to an automatic labeling machine for beverage bottles. Background Technology
[0002] Labeling machines are devices that affix rolls of self-adhesive labels to bottled products or prescribed packaging. In existing technologies, beverage bottles often accumulate dust and impurities on their outer walls during other production lines or transportation. After labeling, larger particles of these impurities can easily cause labels to blister or not adhere firmly, reducing the quality and pass rate of labeling. Therefore, there is an urgent need for an automatic beverage bottle labeling machine to solve these technical problems. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a labeling machine body, which includes a frame, a conveyor and a labeling assembly mounted on the frame; a bottle blowing assembly is provided at the feed end of the conveyor, the bottle blowing assembly includes a support bracket and an annular blowing pipe, the support bracket is fixedly connected to the frame, a vertical telescopic rod is fixedly fixed at the top of the support bracket, the telescopic end of the vertical telescopic rod is vertically downward and fixedly connected to a connecting plate, a second vertical telescopic rod is fixedly fixed on the connecting plate, the telescopic end of the second vertical telescopic rod is vertically downward and fixedly connected to the blowing pipe, multiple air outlets are evenly distributed on the inner annular surface of the blowing pipe, the blowing pipe is connected to an air inlet pipe, the air inlet pipe is a spring pipe, the air inlet pipe is connected to an air pump or air compressor, the conveyor can be a chain conveyor, and the first and second vertical telescopic rods are electric push rods or hydraulic rods. Beverage bottles requiring labeling are placed one by one on the conveyor chain. As the conveyor transports the bottles to the center of the connecting plate, the chain stops moving, the second vertical telescopic rod extends, and the air blower moves downwards. During this movement, an air source supplies air to the blowing ring, which is then sprayed onto the beverage bottles through the air outlets. This blows away any sticky impurities from the outer surface of the bottles, improving the quality of the subsequent labeling process. After blowing, the air blower moves upwards, the conveyor chain resumes its rotation, and the blown bottles are transported away for labeling. Unblown bottles are moved to the bottom of the connecting plate, and the blowing process is repeated. The combination of the first and second vertical telescopic rods increases the vertical movement distance, making the system more versatile.
[0004] Preferably, the frame is further provided with a bottle-sorting assembly, which includes a first baffle and a second baffle. The first baffle and the second baffle are respectively set on both sides of the conveyor surface of the conveyor by a support member. The support member includes a column and a horizontal telescopic rod. The lower end of the column is fixed to the frame, and the upper end of the column is connected to the fixed end of the horizontal telescopic rod. The telescopic end of the horizontal telescopic rod is connected to the corresponding first baffle or second baffle. The horizontal telescopic rod is an electric push rod or a hydraulic rod. The beverage bottle passes between the first baffle and the second baffle, making its position on the conveyor more conducive to subsequent labeling operations. The distance between the first baffle and the second baffle can be adjusted by extending and retracting the horizontal telescopic rod, which is suitable for bottle sorting operations of beverage bottles of different sizes.
[0005] Preferably, the discharge end of the conveyor is equipped with an inspection area, which is fixed to the frame. The inlet of the inspection area is equipped with a guide plate located at the discharge end of the conveyor. The guide plate guides the labeled beverage bottles from the conveyor into the inspection area, where manual or machine inspection can be performed. Products with unqualified labels are rejected, and qualified products are packaged.
[0006] Preferably, the labeling assembly includes a second bracket, on which a support plate is mounted. The support plate is equipped with a feeding roller, a labeling roller, and a take-up roller. The lower ends of the feeding roller, labeling roller, and take-up roller are rotatably connected to the support plate via bearings. A motor is connected to the lower end of the take-up roller. Multiple transition rollers are mounted on the support plate between the feeding roller and the labeling roller, with their lower ends rotatably connected to the support plate via bearings. A roll of self-adhesive label tape is placed on the feeding roller. One end of the self-adhesive label tape passes sequentially through the transition roller and the labeling roller before being fixed to the take-up roller. When a beverage bottle passes the labeling roller on the conveyor belt, the label is affixed to the bottle under the action of the labeling roller and the first baffle. The take-up roller then rotates, rewinding the self-adhesive label tape. The remaining unattached label is positioned at the labeling roller, awaiting labeling when the next beverage bottle passes by.
[0007] Preferably, the second baffle and the labeling assembly are located on the same side of the conveyor, the ends of the first baffle and the second baffle that are close to the feed end of the conveyor are flush, the length of the first baffle is greater than the length of the second baffle, and the first baffle cooperates with the labeling assembly.
[0008] Preferably, the air pump is equipped with a filter screen at the air inlet. The filter screen can remove impurities in the air, making the air blown out by the blower cleaner and avoiding secondary pollution to the beverage bottle.
[0009] Preferably, an infrared sensor is located at the center of the lower surface of the connecting plate, and the infrared sensor is electrically connected to the second vertical telescopic rod. A control box is mounted on the frame, containing a controller. The infrared sensor, conveyor belt, first vertical telescopic rod, second vertical telescopic rod, horizontal telescopic rod, and air pump or compressor are all electrically connected to the controller, which controls their operation. When a beverage bottle moves to the area below the connecting plate, the infrared sensor transmits a signal to the controller, which then issues a command to stop the conveyor and initiate the blowing operation of the bottle blowing assembly.
[0010] This utility model also includes other components that enable the automatic labeling machine for beverage bottles to operate normally, such as control components for the motor, air source, conveyor, vertical telescopic rod one, vertical telescopic rod two, horizontal telescopic rod, and infrared sensor, all of which are conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as conveyors, electric push rods, hydraulic rods, motors, infrared sensors, air pumps, air compressors, and controllers, all employ conventional technologies and equipment in the field.
[0011] Working principle: Beverage bottles to be labeled are placed one by one on the conveyor belt. As the conveyor belt transports the bottles to the center of the connecting plate, it stops. The vertical telescopic rod extends, and the air blower moves downwards. During this movement, the air source supplies air to the blowing ring, which is then sprayed onto the beverage bottles through the air outlets. This blows away any sticky impurities from the outer surface of the bottles, improving the quality of the subsequent labeling process. After the blowing is complete, the air blower moves upwards, the conveyor belt resumes operation, and the blown bottles move towards the labeling assembly. Unblown bottles move to the bottom of the connecting plate, and the blowing process is repeated.
[0012] When beverage bottles are transported on the conveyor belt, they pass between baffle one and baffle two, making their position on the conveyor belt more favorable for the subsequent labeling operation of the labeling roller. The distance between baffle one and baffle two can be adjusted by extending and retracting the horizontal telescopic rod, which is suitable for bottle handling operations of different sizes of beverage bottles.
[0013] This invention has the following advantages: Before labeling beverage bottles, a blowing operation can be performed to reduce the adhesion of impurities on the surface of the beverage bottles, and avoid bulging or poor adhesion caused by the presence of large particles of impurities during labeling, thereby improving the quality of labeling and benefiting production.

[0019] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.
[0020] Example 1
[0021] like Figure 1-2As shown, this utility model provides an automatic labeling machine for beverage bottles, including a labeling machine body. The labeling machine body includes a frame 2, on which a conveyor and a labeling assembly are mounted. The feed end of the conveyor is equipped with a bottle blowing assembly. The bottle blowing assembly includes a support bracket 13 and an annular blowing pipe 17. The support bracket 13 is fixedly connected to the frame 2. A vertical telescopic rod 14 is fixed to the top of the support bracket 13. The telescopic end of the vertical telescopic rod 14 points vertically downward and is fixedly connected to a connecting plate 16. A vertical telescopic rod 19 is fixed on the connecting plate 16. Both the first and second vertical telescopic rods are electric push rods or hydraulic rods. The telescopic end of the second vertical telescopic rod 19 points vertically downward and is fixedly connected to the air blowing pipe 17. Multiple air outlets 20 are evenly distributed on the inner ring surface of the air blowing pipe 17. The air blowing pipe 17 is connected to an air inlet pipe, which is a spring tube 18. The spring tube is connected to an air pump 15 or an air compressor. The air pump 15 or air compressor can be fixed on the bracket. The conveyor is a chain conveyor. Beverage bottles that need to be labeled are placed one by one on the conveyor chain plate 3 of the conveyor. After the conveyor reaches the center of the connecting plate 16, the conveyor chain plate 3 stops driving, the second vertical telescopic rod 19 extends, and the air blowing pipe 17 moves from top to bottom. During the movement, the air inlet pipe delivers air to the air blowing ring. The air is sprayed onto the beverage bottle through the air outlets 20, blowing away the sticky impurities on the outer surface of the beverage bottle, which helps to improve the quality of the next labeling step. After the blowing is completed, the blowing pipe 17 moves upward, the conveyor chain plate resumes transmission, and the blown bottles are transported away by the conveyor for labeling. When the unblown beverage bottles move to below the connecting plate 16, the above blowing operation can be repeated.
[0022] The conveyor has an inspection area 11 at its discharge end, which is fixed to the frame. A guide plate 12 is located at the inlet of the inspection area 11. The guide plate 12 guides labeled beverage bottles from the conveyor into the inspection area 11 for manual or machine inspection (e.g., using a vision inspection system). Products with non-compliant labels are rejected, and qualified products are packaged.
[0023] In this embodiment, an air filter can be installed at the air inlet of the air pump 15 (Xinweicheng PCF series). The air filter can remove impurities from the air, making the air blown out by the blower pipe 17 cleaner and avoiding secondary pollution to the beverage bottle. Alternatively, an air compressor with a filter at the air inlet can be used directly; the air compressor model can be KJ40.
[0024] Example 2
[0025] like Figure 1-2As shown, the difference between this embodiment and Embodiment 1 is that an infrared sensor (such as an Omron B5W series sensor) is located at the center of the lower surface of the connecting plate 16. This infrared sensor is electrically connected to the second vertical telescopic rod 19. A control box 1 is mounted on the frame 2, containing a controller (PLC controller). The infrared sensor, conveyor belt 3, first vertical telescopic rod 14, second vertical telescopic rod 19, horizontal telescopic rod 6, air pump 15, and air compressor are all electrically connected to the controller, which controls their operation. When the beverage bottle moves below the connecting plate 16, the infrared sensor transmits a signal to the controller, which then issues a command to stop the conveyor and initiate the blowing operation of the bottle blowing assembly.
[0026] Example 3
[0027] like Figure 3 As shown, this embodiment provides an automatic labeling machine for beverage bottles, including a labeling machine body. The labeling machine body includes a frame 2, on which a conveyor and labeling components are mounted. A bottle-sorting component is also mounted on the frame 2, including a first baffle 4 and a second baffle 21. The first baffle 4 and the second baffle 21 are respectively mounted on opposite sides of the conveyor surface via support members. The support members include a column 5 and a horizontal telescopic rod 6. The lower end of the column 5 is fixed to the frame 2, and the upper end of the column 5 is connected to the fixed end of the horizontal telescopic rod 6. The telescopic end of the horizontal telescopic rod 6 is connected to the corresponding first baffle 4 or second baffle 21. The horizontal telescopic rod is an electric push rod or a hydraulic rod. Beverage bottles pass between the first baffle 4 and the second baffle 21, making their position on the conveyor more advantageous for subsequent labeling operations. The distance between the first baffle 4 and the second baffle 21 can be adjusted by extending and retracting the horizontal telescopic rod 6, making it suitable for sorting beverage bottles of different sizes.
[0028] The discharge end of the conveyor is equipped with an inspection area 11, which is fixed on the frame. The inlet of the inspection area 11 is provided with a guide plate 12. The guide plate 12 guides the labeled beverage bottles on the conveyor into the inspection area 11, where manual or machine inspection can be performed. Products with unqualified labels are rejected, and qualified products are packaged.
[0029] The frame 2 is also equipped with a labeling assembly, which includes a bracket 2 with a support plate. The support plate has a feeding roller 7, a labeling roller 9, and a take-up roller 10. The lower ends of the feeding roller 7, the labeling roller 9, and the take-up roller 10 are rotatably connected to the support plate via bearings. The lower end of the take-up roller 10 is connected to a motor. The support plate between the feeding roller 7 and the labeling roller 9 has multiple transition rollers 8, the lower ends of which are rotatably connected to the support plate via bearings. A roll of self-adhesive label tape is placed on the feeding roller 7. One end of the self-adhesive label tape passes through the transition roller 8 and the labeling roller 9 in sequence and is then fixed on the take-up roller 10. When a beverage bottle passes the labeling roller 9 on the conveyor belt 3, the label is affixed to the beverage bottle under the action of the labeling roller 9 and the baffle 4. Then, the take-up roller 10 rotates to rewind the self-adhesive label tape. Another unattached label is located at the labeling roller 9, waiting to be labeled when the next beverage bottle passes by.
[0030] The second baffle 21 and the labeling assembly are located on the same side of the conveyor. The first baffle 4 and the second baffle 21 are flush with the feed end of the conveyor. The length of the first baffle 4 is greater than the length of the second baffle 21. The first baffle 4 cooperates with the labeling assembly.
[0031] Example 4
[0032] like Figure 1-2 As shown, the difference between this embodiment and Embodiment 2 is that the frame 2 is equipped with a bottle-sorting assembly. This assembly includes a first baffle 4 and a second baffle 21. The first baffle 4 and the second baffle 21 are respectively mounted on opposite sides of the conveyor via support members. The support members include a column 5 and a horizontal telescopic rod 6. The lower end of the column 5 is fixed to the frame 2, and the upper end of the column 5 is connected to the fixed end of the horizontal telescopic rod 6. The telescopic end of the horizontal telescopic rod 6 is connected to the corresponding first baffle 4 or second baffle 21. The horizontal telescopic rod is either an electric push rod or a hydraulic rod. Beverage bottles pass between the first baffle 4 and the second baffle 21, making their position on the conveyor more advantageous for subsequent labeling operations. The distance between the first baffle 4 and the second baffle 21 can be adjusted by extending and retracting the horizontal telescopic rod 6, making it suitable for sorting beverage bottles of different sizes.
[0033] The labeling assembly includes a second bracket, on which a support plate is provided. The support plate is provided with a feeding roller 7, a labeling roller 9, and a take-up roller 10. The lower ends of the feeding roller 7, the labeling roller 9, and the take-up roller 10 are all rotatably connected to the support plate through bearings. The lower end of the take-up roller 10 is connected to a motor. The support plate between the feeding roller 7 and the labeling roller 9 is provided with multiple transition rollers 8. The lower ends of the transition rollers 8 are rotatably connected to the support plate through bearings. The roll of self-adhesive label tape is placed on the feeding roller 7. One end of the self-adhesive label tape passes through the transition roller 8 and the labeling roller 9 in sequence and is then fixed on the take-up roller 10. When the beverage bottle passes the labeling roller 9 on the conveyor, the label is affixed to the beverage bottle under the action of the labeling roller 9 and the baffle 4. During labeling, the baffle 4 can limit the beverage bottle to prevent it from tipping over when the labeling roller affixes the label to the beverage bottle. Then the take-up roller 10 rotates to rewind the self-adhesive label tape. Another unattached label is located at the labeling roller 9, waiting to be labeled when the next beverage bottle passes by.
[0034] The second baffle 21 and the labeling assembly are located on the same side of the conveyor. The first baffle 4 and the second baffle 21 are flush with the feed end of the conveyor.
