Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical equipment technology, and particularly relates to a rubber stopper delivery mechanism and method. Background Technology

[0002] For rubber stoppers with similar diameters at both ends, it is difficult to distinguish their front and back using a vibrating bucket. For example, the rubber stoppers for cartridge bottles are rubber stoppers with similar heights at both ends, and the difference in diameter between the two ends is only 0.1mm. After sorting, the end with the larger diameter of the rubber stopper should face the bottle and be inserted into the bottle. During the sorting process, it is necessary to distinguish the front and back of the cartridge bottle rubber stoppers. The rubber stoppers are transported by a suspended slide rail, which has low sorting efficiency and the defect of difficulty in distinguishing the front and back of the rubber stoppers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a rubber stopper conveying mechanism and method that can improve the efficiency of rubber stopper material handling.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A rubber stopper conveying mechanism includes a material handling channel 2, which comprises a feeding channel 21, a first discharge screening channel 22, a forward and reverse screening channel 23, and a second discharge screening channel 24 connected sequentially. The outlet of the feeding channel 21 is located above the inlet of the first discharge screening channel 22. The first discharge screening channel 22 has a first through hole 221 on its side for removing horizontally conveyed rubber stoppers. The forward and reverse screening channel 23 is used to change the conveying state of vertically conveyed rubber stoppers with the larger diameter end facing down to horizontal conveying. The second discharge screening channel 24 has a second through hole 241 on its side for removing horizontally conveyed rubber stoppers. This allows the rubber stoppers to change their conveying state multiple times and screen rubber stoppers in different conveying states, achieving rubber stopper material handling with high efficiency and accurate differentiation of the forward and reverse sides of the rubber stoppers.

[0006] As a further improvement to the above technical solution:

[0007] The feeding channel is connected to the vibrating bucket body 1. The feeding channel 21 is a curved upward channel, so that when the rubber plug moves along the feeding channel 21, it is basically conveyed horizontally.

[0008] The first through hole 221 has a height of H1 and a length of L1, the second through hole 241 has a height of H2 and a length of L2, the rubber stopper has a height of h, and the maximum diameter of the rubber stopper is R1, wherein H1 > R1, L1 > h, H2 > R1, and L2 > h, so that the horizontally conveyed rubber stopper can leave the material handling channel 2 through the first through hole 221 and the second through hole 241.

[0009] The width of the feed inlet of the forward and reverse screening channel 23 is W. The diameters of the two ends of the rubber stopper are R1 and R2, respectively, where R1 > R2 and R1 > W ≥ R2. This prevents the rubber stopper with one end of diameter R1 facing down and being conveyed vertically from entering the feed inlet of the forward and reverse screening channel 23 vertically, while the rubber stopper with one end of diameter R2 facing down and being conveyed vertically can enter the feed inlet of the forward and reverse screening channel 23 vertically, thereby performing forward and reverse screening on the vertically conveyed rubber stopper.

[0010] A stop block 231 is provided on one side of the bottom of the forward and reverse screening channel 23, and a side baffle 232 is provided on the other side of the forward and reverse screening channel 23. A vertical conveying channel for rubber plugs is formed between the side of the stop block 231 and the side baffle 232. The stop block 231 can be adjusted and installed on the forward and reverse screening channel 23. A horizontal conveying channel for rubber plugs is formed between the upper surface of the stop block 231 and the side baffle 232. A rubber plug with a diameter of R1 facing down and conveyed vertically cannot enter the feed port of the forward and reverse screening channel 23 vertically. It is blocked by the stop block 231, thereby changing the conveying state to horizontal conveying and conveying on the upper surface of the stop block 231.

[0011] The first through hole 221 and the second through hole 241 connect the vibrating bucket body 1, so that the horizontally conveyed rubber plugs return to the vibrating bucket body 1 and re-enter the material handling channel 2 for material handling.

[0012] The material handling channel 2 also includes a tilting channel 25. The second material discharge screening channel 24 is connected to the tilting channel 25. The two sides of the tilting channel 25 are provided with spiral side plates 251. The rubber plug is tilted 180 degrees through the tilting channel 25 so that the end with the larger diameter of the rubber plug is conveyed downwards.

[0013] The material handling channel 2 also includes a discharge channel 25. The flipping channel 25 is connected to the discharge channel 26. An upper baffle 27 is provided above the connection between the discharge channel 26 and the flipping channel 25. The number of discharge channels 26 is greater than the number of flipping channels 25. The upper baffle 27 prevents the rubber plugs from overlapping and changing direction, and keeps the larger diameter end facing down, so as to output the material handling channel 2.

[0014] Multiple material handling channels are arranged in parallel, with a reasonable structural layout that improves material handling efficiency.

[0015] A method for conveying rubber plugs includes a rubber plug conveying mechanism. Rubber plugs enter a feeding channel 2 and fall from a height through a feeding channel 21 to a first discharge screening channel 22. Once in the first discharge screening channel 22, the rubber plugs are either conveyed horizontally, vertically with the larger diameter end facing down, or vertically with the smaller diameter end facing down. Horizontally conveyed rubber plugs exit the feeding channel 2 through a first through-hole 221. The remaining rubber plugs enter a forward and reverse screening channel 23. The rubber plugs with the larger diameter end facing down that were vertically conveyed are blocked in the forward and reverse screening channel 23 and their conveying direction is changed to horizontal before entering the first discharge screening channel 22. In the second discharge screening channel 24, the vertically conveyed rubber plugs with the smaller diameter end facing down are kept in this transport state and enter the second discharge screening channel 24. The horizontally conveyed rubber plugs in the second discharge screening channel 24 leave the material handling channel 2 through the second through hole 241. The vertically conveyed rubber plugs with the smaller diameter end facing down are kept in this transport state and enter the flipping channel 25. The flipping channel 25 flips the rubber plugs so that the larger diameter end faces down and is conveyed in the output direction. The vertically conveyed rubber plugs enter the discharge channel 26, completing the material handling output, realizing the separation of the positive and negative rubber plugs, and the material handling efficiency is high.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] The present invention discloses a rubber stopper conveying mechanism and method. The rubber stopper moves along the material handling channel 2 and falls from the feeding channel 21 to the first discharge screening channel 22, so that most of the rubber stoppers are changed from horizontal conveying to vertical conveying. Through the forward and reverse screening channel 23, the rubber stoppers with the smaller diameter end facing down in vertical conveying are screened out, thus completing the screening of rubber stoppers. The material handling channel 2 has a simple structure and a reasonable channel docking layout, which can realize the distinction between the forward and reverse sides of the rubber stopper and has high material handling efficiency.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, a rubber stopper conveying mechanism includes a material handling channel 2. The material handling channel 2 includes a feeding channel 21, a first discharge screening channel 22, a forward and reverse screening channel 23, and a second discharge screening channel 24 connected in sequence. The outlet of the feeding channel 21 is located above the inlet of the first discharge screening channel 22. The side of the first discharge screening channel 22 is provided with a first through hole 221 for removing horizontally conveyed rubber stoppers. The forward and reverse screening channel 23 is used to change the conveying state of vertically conveyed rubber stoppers with the larger diameter end facing down to horizontal conveying. The side of the second discharge screening channel 24 is provided with a second through hole 241 for removing horizontally conveyed rubber stoppers. This allows the rubber stoppers to change their conveying state multiple times and screen rubber stoppers in different conveying states, achieving rubber stopper material handling with high efficiency and accurate differentiation of forward and reverse rubber stoppers.

[0025] The feeding channel is connected to the vibrating bucket body 1. The feeding channel 21 is a curved upward channel. When the rubber plugs move along the feeding channel 21, they are basically conveyed horizontally. Due to the different diameters at both ends of the rubber plugs, during the process of being conveyed upwards by the vibrating bucket body 1 to the curved feeding channel 21, the rubber plugs that are conveyed horizontally upwards are more likely to have the larger diameter end at the bottom than the smaller diameter end at the bottom. When the height difference between the feeding channel 21 and the first discharge screening channel 22 causes the horizontally conveyed rubber plugs to fall and become vertical, most of the rubber plugs are at the smaller diameter end at the bottom and are conveyed vertically. Only a small number of rubber plugs, due to the very small difference in diameter between the two ends, are at the larger diameter end at the bottom and are conveyed vertically.

[0026] The first through hole 221 has a height of H1 and a length of L1, the second through hole 241 has a height of H2 and a length of L2, the rubber stopper has a height of h, and the maximum diameter of the rubber stopper is R1, wherein H1 > R1, L1 > h, H2 > R1, and L2 > h, so that the horizontally conveyed rubber stopper can leave the material handling channel 2 through the first through hole 221 and the second through hole 241.

[0027] The width of the feed inlet of the forward and reverse screening channel 23 is W. The diameters of the two ends of the rubber stopper are R1 and R2, respectively, where R1 > R2 and R1 > W ≥ R2. This prevents the rubber stopper with one end of diameter R1 facing down and being conveyed vertically from entering the feed inlet of the forward and reverse screening channel 23 vertically, while the rubber stopper with one end of diameter R2 facing down and being conveyed vertically can enter the feed inlet of the forward and reverse screening channel 23 vertically, thereby performing forward and reverse screening on the vertically conveyed rubber stopper.

[0028] A stop block 231 is provided on one side of the bottom of the forward and reverse screening channel 23, and a side baffle 232 is provided on the other side of the forward and reverse screening channel 23. A vertical conveying channel for rubber plugs is formed between the side of the stop block 231 and the side baffle 232. The stop block 231 is adjustablely installed on the forward and reverse screening channel 23. The stop block 231 is provided with a waist-shaped hole. The stop block 231 is installed on the forward and reverse screening channel 23 by passing a locking member through the waist-shaped hole. By adjusting the position of the stop block 231, the width W of the feed inlet can be set more accurately. A horizontal conveying channel for rubber plugs is formed between the upper surface of the stop block 231 and the side baffle 232. A rubber plug with a diameter of R1 facing down and conveyed vertically cannot enter the feed inlet of the forward and reverse screening channel 23 vertically. It is blocked by the stop block 231, thereby changing the conveying state to horizontal conveying and conveying on the upper surface of the stop block 231.

[0029] The first through hole 221 and the second through hole 241 connect the vibrating bucket body 1, so that the horizontally conveyed rubber plugs return to the vibrating bucket body 1 and re-enter the material handling channel 2 for material handling.

[0030] The material handling channel 2 also includes a tilting channel 25. The second material discharge screening channel 24 is connected to the tilting channel 25. The two sides of the tilting channel 25 are provided with spiral side plates 251. The rubber plug is tilted 180 degrees through the tilting channel 25 so that the end with the larger diameter of the rubber plug is conveyed downwards.

[0031] The material handling channel 2 also includes a discharge channel 25, a flipping channel 25 that connects to a discharge channel 26, and an upper baffle 27 above the connection point between the discharge channel 26 and the flipping channel 25. The number of discharge channels 26 is greater than the number of flipping channels 25. For example, there are three flipping channels 25 and eight discharge channels 26. The upper baffle 27 prevents the rubber plugs coming out of the flipping channel 25 from overlapping and changing direction when entering the discharge channel 26, so that the rubber plugs are kept in a downward orientation with the larger diameter end facing down, and are output from the material handling channel 2.

[0032] Multiple material handling channels 2 are arranged in parallel, and multiple material handling channels 2 can handle materials simultaneously. All material handling channels are arranged in parallel on the vibrating bucket body 1, with a reasonable structural layout, which improves material handling efficiency.

[0033] A method for conveying rubber plugs includes a rubber plug conveying mechanism. Rubber plugs enter a feeding channel 2 and fall from a height through a feeding channel 21 to a first discharge screening channel 22. Once in the first discharge screening channel 22, the rubber plugs are either conveyed horizontally, vertically with the larger diameter end facing down, or vertically with the smaller diameter end facing down. Horizontally conveyed rubber plugs exit the feeding channel 2 through a first through-hole 221. The remaining rubber plugs enter a forward and reverse screening channel 23. The rubber plugs with the larger diameter end facing down that were vertically conveyed are blocked in the forward and reverse screening channel 23 and their conveying direction is changed to horizontal before entering the first discharge screening channel 22. In the second discharge screening channel 24, the vertically conveyed rubber plugs with the smaller diameter end facing down are kept in this transport state and enter the second discharge screening channel 24. The horizontally conveyed rubber plugs in the second discharge screening channel 24 leave the material handling channel 2 through the second through hole 241. The vertically conveyed rubber plugs with the smaller diameter end facing down are kept in this transport state and enter the flipping channel 25. The flipping channel 25 flips the rubber plugs so that the larger diameter end faces down and is conveyed in the output direction. The vertically conveyed rubber plugs enter the discharge channel 26, completing the material handling output, realizing the separation of the positive and negative rubber plugs, and the material handling efficiency is high.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
