Description

Technical Field

[0001] This utility model relates to the field of ampoule processing equipment technology, and in particular to a medicine bottle conveying mechanism. Background Technology

[0002] Ampoules are widely used packaging containers in pharmaceutical packaging. The text information on their surface, including the name of the medicine, volume, production date, batch number, etc., is related to the user's life safety. Accordingly, the printing of this information requires an ampoule printing machine. An ampoule printing machine mainly consists of an ampoule conveying mechanism and a printing mechanism. The ampoule conveying mechanism moves the ampoule, and the printing machine prints the text on the bottle. After printing, the conveyor automatically carries the ampoule into a packaging box, thus completing the printing on the ampoule and the packaging of the bottle.

[0003] Ampoule conveyors often use chain conveyors. When the ampoules are transported to the packaging box, they detach from the conveyor. A device is usually needed to keep the ampoules attached to the conveyor until they rotate to the next process point, where they finally detach from the chain under gravity. Current technology typically uses a crescent-shaped baffle at the conveyor's output end to prevent ampoules from detaching during transport. However, these baffles are usually fixed to the frame. If the ampoule's position changes during transport, it is prone to collision, falling, or even breaking, impacting production efficiency and causing losses. Therefore, there is an urgent need for a medicine bottle conveying mechanism that can react to the ampoule's position to reduce the probability of breakage. Utility Model Content

[0004] The purpose of this invention is to provide a medicine bottle conveying mechanism that can make an early warning response based on the position changes of the ampoule during the conveying process, reduce the probability of the ampoule falling and breaking during the conveying process, reduce economic losses, and ensure production efficiency.

[0005] The present invention adopts the following technical solution:

[0006] A medicine bottle conveying mechanism includes a frame, a chain conveyor mounted on the frame, a support at the output end of the chain conveyor, a crescent-shaped baffle movable along its length on the support, a detection rod on one side of the crescent-shaped baffle, the detection rod initially contacting a detection switch mounted on the frame; a pneumatically controlled disc is mounted behind the crescent-shaped baffle, and a conveying track is mounted below the disc.

[0007] Preferably, a slide rail is provided on the inner side of the bracket, a connecting plate is provided on one side of the crescent-shaped baffle, a slide groove is provided on the connecting plate to slide in contact with the slide rail, and a first return spring is provided between the connecting plate and the bracket.

[0008] Preferably, the flower disc is provided with a plurality of teeth grooves evenly arranged along its circumference, and each tooth groove is provided with an air hole that is connected to the air source pipe. The side of the flower disc away from the crescent-shaped baffle is connected to the pneumatic slip ring through the air source pipe; the pneumatic slip ring is connected to the solenoid valve.

[0009] Preferably, a detection frame is provided below the flower plate, a slider that can slide up and down is provided on the detection frame, a detection plate is provided at the bottom of the slider, and a trigger switch is provided below the detection plate.

[0010] Preferably, the slider is elastically mounted on the detection frame by a second reset spring.

[0011] Preferably, the detection frame is threaded with an adjusting rod, and the slider has a through hole for the adjusting rod to pass through; both the adjusting rod and the through hole have a T-shaped cross-section, the second return spring is located in the larger diameter space inside the through hole, and the second return spring is sleeved on the outside of the adjusting rod.

[0012] Preferably, the two sides of the testing frame are arc-shaped structures.

[0013] Preferably, the connecting plate is provided with an oblong adjustment hole, and the crescent-shaped baffle is connected to the connecting plate through the adjustment hole using bolts.

[0014] Preferably, a limiting plate is provided on the bracket, and a limiting rod is provided on the connecting plate on one side of the crescent-shaped baffle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By sliding the crescent-shaped baffle on the bracket, when the ampoule on the chain conveyor is not in the correct position, as the ampoule enters the crescent-shaped baffle, it generates a pushing force that causes the crescent-shaped baffle to move away from the chain conveyor along the bracket. At this time, the detection rod will disengage from the detection switch, and the PLC will immediately stop the machine for maintenance after receiving the relevant signal. This reduces the probability of the ampoule breaking during the conveying process, ensures production efficiency, and reduces economic losses. Attached Figure Description

[0023] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 7 As shown, the present invention provides a medicine bottle conveying mechanism, including a frame 1, on which a chain conveyor 2 is mounted for the orderly conveying of ampoules; a support 3 is mounted at the output end of the chain conveyor 2, and the support 3 is connected to the frame 1; a crescent-shaped baffle 4 is mounted on the support 3 and can move along its length direction; the crescent-shaped baffle 4 has an arc-shaped guide opening on the side facing the chain conveyor 2 so as to match with the end of the chain conveyor 2 to complete the conveying of ampoules; a detection rod 7 is mounted on one side of the crescent-shaped baffle 4, and in the initial state, the detection rod 7 is in contact with a detection switch 8 mounted on the frame 1; a pneumatically controlled flower plate 5 is mounted on the rear side of the crescent-shaped baffle 4 along the ampoule conveying direction, and a conveying track 6 is mounted on the lower side of the flower plate 5. During operation, ampoules are conveyed by the chain conveyor 2 and output from the lower end of the crescent-shaped baffle 4. The flower disc 5 picks up the ampoules one by one and transports them to the conveyor track 6. The conveyor track 6 and subsequent workstations cooperate to complete the conveying operation. If the position of an ampoule on the chain conveyor 2 is incorrect during the conveying process, it will exert a pushing force on the crescent-shaped baffle 4 when it moves to it, causing the crescent-shaped baffle 4 to move away from the chain conveyor 2. At this time, the detection rod 7 disengages from the detection switch 8. After receiving the relevant signal, the equipment PLC will immediately control the machine to stop for timely inspection and adjustment, avoiding the breakage of ampoules due to continued conveying. This greatly reduces the breakage rate of ampoules and reduces economic losses in the production process.

[0025] Furthermore, a slide rail 9 is provided on the inner side of the bracket 3, and a connecting plate 10 is provided on one side of the crescent-shaped baffle 4. The connecting plate 10 is provided with a sliding groove that slides in contact with the slide rail 9, and a first return spring is provided between the connecting plate 10 and the bracket 3. When the crescent-shaped baffle 4 moves away from the chain conveyor 2, the first return spring is stretched, the detection rod 7 disengages from the detection switch 8, and the equipment stops. Since the first return spring has a certain restoring force, the ampoules with incorrect positioning will be clamped between the crescent-shaped baffle 4 and the chain conveyor 2, preventing the ampoules from falling, reducing the probability of ampoule breakage, and reducing economic losses.

[0026] Furthermore, the connecting plate 10 is provided with a waist-shaped adjustment hole 11, and the crescent-shaped baffle 4 is connected to the connecting plate 10 via the adjustment hole 11 using bolts. The waist-shaped adjustment hole 11 helps to fine-tune the position of the crescent-shaped baffle 4 to meet the needs of use in various situations, enhancing the practicality of this utility model. In addition, in this embodiment, the bracket 3 is also provided with a limiting plate 12, and the connecting plate 10 on one side of the crescent-shaped baffle 4 is provided with a limiting rod 13. Through the contact between the limiting rod 13 and the limiting plate 12, the crescent-shaped baffle 4 can be limited during reset, preventing it from moving rapidly under the elastic restoring force and causing damage to the ampoule during reset. In addition, the limiting rod 13 is threaded on the connecting plate 10, so that by rotating the limiting rod 13, its length extending from the connecting plate 10 can be adjusted, changing the distance between the connecting plate 10 and the limiting plate 12, thereby adjusting the distance between the crescent-shaped baffle 4 and the chain conveyor 2, thus meeting the needs of conveying different ampoules.

[0027] Furthermore, the flower disc 5 is evenly provided with multiple toothed grooves 14 along its circumference. Each toothed groove 14 is provided with an air hole that is connected to the air source pipe 15. The side of the flower disc 5 away from the crescent baffle 4 is connected to the pneumatic slip ring through the air source pipe 15. The pneumatic slip ring is connected to the solenoid valve 16 so that the PLC of the equipment can control the vacuum valve to open and realize the adsorption of ampoules. During operation, the flower disc 5 rotates and uses the toothed grooves 14 to adsorb and pick up the ampoules output from the bottom of the crescent baffle 4 one by one. Using vacuum adsorption to pick up ampoules can avoid rubbing off the lettering printed on the ampoules and ensure production quality.

[0028] Furthermore, a detection frame 17 is installed below the flower tray 5. The detection frame 17 has an arc-shaped structure on both sides to facilitate its use with the chain conveyor 2 and the flower tray 5. A sliding block 18 is installed on the detection frame 17, and a detection plate 19 is installed at the bottom of the sliding block 18. A trigger switch 20 is installed below the detection plate 19. When the vacuum of the flower tray 5 is not working and cannot adsorb the ampoules, the ampoules will fall onto the sliding block 18 below. The sliding block 18 moves downward under the force, causing the detection plate 19 to move down and contact the trigger switch 20. At this time, the PLC receives the relevant signal and issues a stop instruction to enable timely maintenance and adjustment. This further reduces the breakage rate of ampoules during operation and avoids a series of subsequent failures, ensuring smooth production.

[0029] Preferably, in this embodiment, the slider 18 is elastically mounted on the detection frame 17 via a second return spring to facilitate the reset of the slider 18. Specifically, an adjusting rod 21 is threaded upwards from the bottom of the detection frame 17, and a through hole 22 is provided on the slider 18 for the adjusting rod 21 to pass through. Both the through hole 22 and the adjusting rod 21 have a T-shaped cross-section, with the larger diameter end located at the bottom and the smaller diameter end located at the top. The second return spring is located in the larger diameter space at the bottom of the through hole 22 and is sleeved on the outside of the adjusting rod 21. The diameter of the second return spring is larger than the diameter of the smaller diameter end at the top of the through hole 22. During operation, by rotating the adjusting rod 21 to extend further into the through hole 22, the second return spring can be compressed, thereby adjusting the elastic force to meet different needs.

[0030] In operation, when an ampoule is mispositioned on the chain conveyor 2, it pushes against the crescent-shaped baffle 4 as it enters the baffle. This causes the detection rod 7 on one side of the baffle 4 to disengage from the detection switch 8. Upon receiving this signal, the equipment's control system immediately stops the machine, thus preventing ampoule breakage and subsequent malfunctions. If the vacuum of the flower disc 5 fails to effectively hold the ampoule, it will fall onto the lower slider 18, pushing it downwards and causing the detection plate 19 to contact the trigger switch 20. Upon receiving this signal, the equipment's control system immediately stops the machine, further preventing ampoule breakage and subsequent malfunctions, saving costs and ensuring production efficiency.
