Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a device for preventing bottles from falling over in a vertical labeling machine. Background Art

[0002] An ampoule is a hard glass container that can be melted and sealed. It is commonly used to store injectable drugs, vaccines, and serums. It is also used to package injectable and oral liquids. The capacity is generally 1 to 25 ml. Currently, in pharmaceutical production plants, after the ampoule is filled with liquid medicine or preparations and sealed, a labeling machine is required to affix labels with relevant information to the outside of the bottle.

[0003] After searching, the Chinese patent publication number CN220577712U discloses a labeling device for veterinary ampoule bottles, including a frame, a support frame, a feeding mechanism, a conveying mechanism, a labeling mechanism and a feeding mechanism. The support frame is arranged on the frame, and the feeding mechanism includes a first motor, a rotating shaft, a rotating plate, a first guide block and a receiving plate. The first motor is arranged on the frame, and the rotating shaft is coaxially connected to the first motor output shaft. The rotating shaft is rotatably connected to the frame, and a plurality of arc holes are provided on the rotating plate. The rotating plate is provided with a plurality of rotating plates, and the rotating plate is sleeved on the rotating shaft. The first guide block is arranged on the frame, and the first guide block is provided with a first guide inclined surface, and the receiving plate is arranged on the frame.

[0004] This patent can reduce the number of collisions between the ampoule nipples, thereby reducing the probability of ampoule nipple breakage. However, as the ampoule moves toward the spiral conveyor roller, there is a high probability that the ampoule will fall over due to the lack of a limiting mechanism. This requires manual shutdown to sort out the fallen ampoule before restarting the machine. This poses a certain safety hazard, and the shutdown and sorting process also consumes a lot of production time. Utility Model Content

[0027] Example 1

[0028] A device for preventing bottles from falling over in a vertical labeling machine, such as Figures 1 to 3 As shown, it includes a loading platform 1 with a feeding screw 2 at one end, a fixing frame 3 is fixed on the top of the loading platform 1, and the inner wall of the top of the fixing frame 3 is connected to the connecting frame 4 through a first driving component, and the bottom end of the connecting frame 4 is connected to a connecting plate 5, and one side of the connecting plate 5 is connected to a push plate 6 through a buffer component, and a sliding groove 10 is provided on the outer wall of one side of the push plate 6, and a push block 7 that slides with the loading platform 1 is provided on one side of the push plate 6, and the push block 7 is slidably connected to the inner wall of the sliding groove 10, and a second driving component is provided on the top of the connecting frame 4, and the moving end of the second driving component is connected to an electric push rod 15, and the telescopic end of the electric push rod 15 is connected to a limiting plate 14.

[0029] The first driving assembly includes a threaded rod 11 and a moving block 12. The threaded rod 11 is rotatably connected to the inner wall of the fixed frame 3. The moving block 12 is slidably fitted with the inner wall of the fixed frame 3. The moving block 12 is threadedly fitted with the threaded rod 11. A motor 13 is installed on the outer wall of one end of the fixed frame 3. The output end of the motor 13 is connected to the threaded rod 11. The moving block 12 is connected to the connecting frame 4. The second driving assembly has the same structure as the first driving assembly.

[0030] The buffer assembly includes a telescopic rod 8 and a spring 9. The telescopic rod 8 is installed on the outer wall of one side of the connecting plate 5. The push plate 6 is connected to the telescopic end of the telescopic rod 8. The spring 9 is sleeved on the outside of the telescopic rod 8. The two ends of the spring 9 are respectively connected to the connecting plate 5 and the push plate 6.

[0031] When feeding, the bottle is placed on the top of the feeding platform 1, the motor 13 in the second driving assembly is started, driving the limit plate 14 to move towards the push plate 6, and the two sides of the bottle are limited and fixed by the limit plate 14 and the push plate 6. The telescopic rod 8 and the spring 9 buffer the contact impact between the bottle and the push plate 6, so that there is no space for the bottle to tip over. Then the motor 13 in the first driving assembly is started, driving the moving block 12 to move along the threaded rod 11, so that the push plate 6 pushes the bottle toward the feeding screw 2. When the limit plate 14 moves to one side of the feeding screw 2, the electric push rod 15 drives the fixed plate 16 to move up, so that the bottle can contact the feeding screw 2 under the push of the push plate 6; when there are fewer bottles, the push block 7 is pushed by the push plate 6 to move toward the feeding screw 2, and the push block 7 contacts the outer wall of the feeding screw 2. It is pushed by the feeding screw 2 to move in one direction along the sliding groove 10, reducing the space where the bottle can tip over.

[0033] By providing the buffer assembly, the contact impact between the bottle body and the push plate 6 can be buffered to prevent the bottle body from being broken by the impact.

[0034] Example 2

[0035] A device for preventing bottles from falling over in a vertical labeling machine. This embodiment makes the following improvements based on embodiment 1: Figures 4 and 5 As shown, the telescopic end of the electric push rod 15 is connected to a guide cylinder 17, and the inner wall of the guide cylinder 17 is slidably fitted with a sliding rod 18. One end of the sliding rod 18 is connected to the limit plate 14. Fixed plates 16 are provided on both sides of the electric push rod 15. The side wall of the fixed plate 16 is provided with a guide groove 19. The inner wall of the bottom end of the guide groove 19 is set as an inclined surface, and guide rods sliding along the guide groove 19 are connected to both sides of the sliding rod 18.

[0036] When the electric push rod 15 contracts, the guide cylinder 17 and the sliding rod 18 drive the limit plate 14 to move, and the guide rod slides along the guide groove 19, causing the sliding rod 18 to contract toward the inside of the guide cylinder 17, so that the limit plate 14 first moves away from the bottle body and then continues to move vertically upward.

[0037] By arranging the electric push rod 15, the fixing plate 16, the guide cylinder 17, the sliding rod 18 and the guide groove 19, when the limiting plate 14 is separated from the bottle body, it first moves away from the bottle body and then continues to move vertically upward, thereby reducing the friction between the limiting plate 14 and the bottle body.

[0038] Working principle: When loading, place the bottle on the top of the loading platform 1, and the motor 13 in the second drive assembly starts, driving the limit plate 14 to approach the push plate 6. The limit plate 14 and the push plate 6 limit and fix both sides of the bottle. The telescopic rod 8 and the spring 9 buffer the contact impact between the bottle and the push plate 6, so that there is no space for the bottle to fall. Then the motor 13 in the first drive assembly starts, driving the moving block 12 to move along the threaded rod 11, so that the push plate 6 pushes the bottle toward the feeding screw 2. When the limit plate 14 moves to one side of the feeding screw 2, The electric push rod 15 drives the fixed plate 16 to move upward, and the guide cylinder 17 and the sliding rod 18 drive the limit plate 14 to move. The guide rod slides along the guide groove 19, causing the sliding rod 18 to retract toward the inside of the guide cylinder 17, so that the limit plate 14 is first away from the bottle body, and then continues to move vertically upward. The bottle body is pushed by the push plate 6 to contact the feeding screw 2; when there are fewer bottles, the push block 7 is pushed by the push plate 6 to approach the feeding screw 2, and the push block 7 contacts the outer wall of the feeding screw 2. It is pushed by the feeding screw 2 to move in one direction along the sliding groove 10, thereby reducing the space where the bottle can be dumped.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
