Description

Technical Field

[0001] This invention belongs to the field of ampoule production technology, and particularly relates to an automatic tube feeding device for ampoule production. Background Technology

[0002] An ampoule is a small, sealed vial made of hard glass that can be melt-sealed. It is commonly used to store injectable drugs, vaccines, serums, and the like.

[0003] The production of ampoules requires material feeding, which is divided into feeding during the scoring stage and feeding inspection during the scoring quality inspection stage. Existing feeding methods include spiral feeding and stacking feeding, which generate a lot of waste and are inconvenient for inspection. In order to reduce waste generation and improve the efficiency of quality inspection, a new type of automatic tube feeding device for ampoule production is proposed, which can effectively meet the feeding needs of unformed ampoules during the scoring stage and the feeding needs of ampoules after forming for quality inspection.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1

[0030] See appendix Figure 1-7As shown, an automatic ampoule feeding device includes an ampoule conveying structure 1 and a feeding conveying structure 3. The ampoule conveying structure 1 and the feeding conveying structure 3 are connected by support legs 2. The ampoule conveying structure 1 includes a conveyor belt 14 and an ampoule placement slot 13 fixedly connected to the conveyor belt 14 by bolts. The ampoule placement slot 13 is provided with internal conveying plates 12 on both sides, and external baffles 11 are provided on both sides of the internal conveying plates 12. The feeding conveying structure 3 is connected to the ampoule... The conveying structure 1 has the same structure. The feeding conveying structure 3 is set horizontally and inclined. The feeding conveying structure 3 is provided with a feeding tray fixing frame 4 on its side. A stepper motor is fixedly connected to the outer surface of the feeding tray fixing frame 4. The stepper motor passes through the surface of the feeding tray fixing frame 4 and is connected to the conveying roller 62. Two feeding tray structures 6 are provided on the conveying roller 62. An ampoule slot 63 is provided on the feeding tray structure 6. A scoring machine 5 is provided above the feeding tray structure 6.

[0031] Preferably, the maximum tilt angle of the feeding and conveying structure 3 is 85°.

[0032] Preferably, the ampoule placement slot 13 has a concave cross-section.

[0033] Preferably, the distance between the outer baffles 11 is consistent with the length of the unformed ampoule 7.

[0034] Preferably, the height of the internal conveying plate 12 is lower than that of the external baffle 11, and the end of the internal conveying plate 12 is provided with an inclined plate 121. The length of the internal conveying plate 12 without the inclined plate 121 is the same as the length of the conveyor belt 14.

[0035] Preferably, the bottom of the feeding conveying structure 3 is lower than the bottom surface of the ampoule conveying structure 1, and the distance between them is at least the height of two ampoule slots 63.

[0036] Preferably, the feeding tray structure 6 includes a conveying roller 62 connected to a stepper motor, a clamping plate 64 is provided on the conveying tray 61, and an ampoule slot 63 is provided between the clamping plates 64.

[0037] Preferably, the outer side of the card plate 64 is provided with a notch, and the direction of the notch is consistent with the rotation direction of the stepper motor.

[0038] Working principle: When feeding unformed ampoules 7, since the main requirement is the scoring in the middle, the ampoules are placed on the ampoule conveying structure 1. The ampoules fall into the ampoule slots 13 as the conveyor belt 14 moves. After adjustment, the unformed ampoules 7 will fall between the outer baffles 11. After being sorted, they are transported to one side. The thinner ends of the ampoules will be on the inclined plate 121, and then they will be fed into the slots of the feeding conveying structure 3. When the highest point is reached, the ampoule slots 13 will flip to one side, and then they can fall into the ampoule slots 63 set on the conveyor turntable 61. At this time, the outer side of the card plate 64 has a notch, and the direction of the notch is consistent with the rotation direction of the stepper motor. When passing the highest point, the scoring will be done by the conveyor turntable 61.

[0039] By organizing and controlling the feeding process, and ensuring a smooth flow throughout, the compression of ampoules is avoided, which effectively achieves stable markings, improves production efficiency, reduces waste, lowers production costs, and increases yield. Example 2

[0040] See appendix Figure 1-4 As shown in Figures 8-10, an automatic tube feeding device for ampoule production is provided. A stepper motor passes through the surface of the feeding tray fixing frame 4 and is connected to a conveying roller 601. The conveying roller 601 is provided with a first chuck 602 and a second chuck 603. Ampoule placement slots 604 are evenly distributed on the outer sides of the first chuck 602 and the second chuck 603. The diameter of the first chuck 602 and the ampoule placement slots 604 are both larger than the second chuck 603. The ampoule placement slots 604 are adapted to the formed ampoule 8.

[0041] Compared with Embodiment 1, the difference lies in replacing the conveyor turntable 61 with a first chuck 602 and a second chuck 603. This reduces the likelihood of ampoules falling due to the mismatch between the ampoule body and the bottle mouth diameter, thus lowering the possibility of damage. Furthermore, with optimization, second chucks 603 can be set on both sides of the first chuck 602, eliminating the need for adjustments to align the bottle body direction and further improving efficiency. This has a good effect on the quality inspection and feeding of the formed ampoule bottles 8, enabling rapid quality inspection and sorting.

[0042] This embodiment uses the same equipment, but only changes the type and number of turntables to meet the requirements of various ampoule feeding, scoring, and quality inspection steps, thus optimizing the equipment structure, reducing the difficulty of training workers, and lowering costs.

[0043] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of the equivalents of the claims be included within the present invention, and no reference numerals in the claims should be regarded as limiting the scope of the claims.
