Description

Technical Field

[0001] This invention relates to the field of oral straw formulation manufacturing technology, and in particular to an oral straw formulation and its filling and assembly equipment and manufacturing method. Background Technology

[0002] In daily life, people often take various medications, including sugar pills and other granules and powders, with water. This often requires swallowing the medication first, followed by drinking water to allow it to enter the stomach for digestion and absorption. This feeding process is cumbersome and prone to choking, causing discomfort. For bedridden individuals, administering medication is even more difficult. With market development, customized tubular containers have emerged, primarily for storing and quickly administering powdered (pill) medications. Currently, most domestic dry powder inhaler manufacturers use manual loading and unloading methods for producing tubular container formulations. Even those using automated equipment typically place the tubular containers horizontally on a conveyor belt. Patent application CN113558987A discloses a pharmaceutical straw and its assembly method, belonging to the field of filled tube technology. The pharmaceutical straw includes a tube body, a filter device at the inlet, and a cap at the outlet. A drug placement area is formed inside the tube body between the filter device and the cap. The filter device includes a filter element and an outer ring, with the filter element embedded within the outer ring. The drug particle size is larger than the pore size of the filter element. The assembly method includes the following steps: 1) inserting the inlet of the tube body into the filter device and fixing it; 2) pouring the drug into the outlet of the tube body; 3) placing the cap at the outlet of the tube body to complete the assembly. The inlet of the pharmaceutical straw in this patent application is inserted into the filter device. Since the powder and the filter device have a certain weight, if there is a deviation in the production process between the filter device and the pharmaceutical straw, resulting in a loose connection, the filter device may detach when it scrapes against the bag wall when the pharmaceutical straw is removed from the bag. Summary of the Invention

[0012] Preferably, the conveying mechanism is a magnetic levitation conveyor line.

[0013] The present invention also provides a method for producing an oral straw formulation, comprising the following steps:

[0014] S1. Loading: The tubular container is transported to the positioning clamping carrier on the conveying mechanism and placed in a vertical position.

[0015] S2. First filter assembly: Insert the first filter into the tubular container;

The tubular container feeding mechanism conveys the tubular container into the positioning and clamping carrier.

This invention enables the automated assembly of a tubular container with two filters, one above and one below, resulting in high production efficiency. Furthermore, the bottom and top fusion-sealing edges effectively prevent the filters from spilling out of the tubular container, avoiding the possibility of them falling off due to scratches. The filters are also less likely to fall off due to manufacturing processes, thus ensuring the quality of oral straw formulations. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] See attached document Figure 2 and attached Figure 3 This embodiment provides an oral straw preparation, including a tubular container 100. A first blocking portion 1001 and a second blocking portion 1002 are respectively provided at the first and second ends of the tubular container 100. Specifically, the bottom of the tubular container 100 is the first end, and the top end is the second end. The first blocking portion 1001 is formed by rolling the edge inward from the bottom opening of the tubular container 100, and the second blocking portion 1002 is formed by rolling the edge inward from the top opening of the tubular container 100. A first filter 12 and a second filter 13 are installed inside the tubular container 100 between the first blocking portion 1001 and the second blocking portion 1002. A region for placing granular medication is formed in the tubular container 100 between the first filter 12 and the second filter 13. Filters are installed at both the upper and lower ends of the tubular container 100, and the granular medication is located between the two filters. The granular medication is blocked inside the tubular container 100 by the two filters, and the two blocking portions block the two filters inside the tubular container 100. This invention utilizes the opening of the tubular container 100 itself to form a first blocking part 1001 and a second blocking part 1002. This structure provides good blocking effect for the filter, avoiding the possibility of the filter falling off due to scratches. The filter will also not fall off due to the manufacturing process, ensuring the quality of oral straw preparations. Furthermore, the first blocking part 1001 and the second blocking part 1002 do not require additional accessories, thus saving costs.

[0032] See attached document Figure 1The present invention also provides a filling and assembly apparatus for the above-mentioned oral straw preparation, including a conveying mechanism 1, a plurality of positioning and clamping carriers 2 are provided on the conveying mechanism 1, the positioning and clamping carriers 2 are used to clamp a plurality of tubular containers 100, and a tubular container feeding mechanism 3, a first filter feeding mechanism 5, a first blocking mechanism 6, a filling mechanism 7, a second filter feeding mechanism 9, a second blocking mechanism 10 and a tubular container unloading mechanism 11 are arranged sequentially along the conveying mechanism 1, the tubular container feeding mechanism 3 is used to convey the tubular containers 100 to the positioning and clamping carriers 2, the first blocking mechanism 6 is used to fill the tubular containers 100, the tubular container feeding mechanism 3 is used to convey the tubular containers 100 to the positioning and clamping carriers 2, the first blocking mechanism 6 is used to fill the tubular containers 100, the tubular container feeding mechanism 3 is used to fill the tubular containers 100, the tubular container feeding mechanism 5 is used to fill the tubular containers 100, the tubular container feeding mechanism 6 ... A first blocking part 1001 is provided at the bottom of the tubular container 100. The filling mechanism 7 is used to fill the powder into the tubular container 100. The second blocking mechanism 10 is used to provide a second blocking part 1002 at the top of the tubular container 100. The first filter feeding mechanism 5 is used to install the first filter 12 into the lower end of the tubular container 100. The first filter feeding mechanism 5 is used to install the second filter 13 into the upper end of the tubular container 100. The tubular container unloading mechanism 11 is used to unload the assembled tubular container 100 (oral straw preparation) from the positioning clamping carrier 2. The tubular container feeding mechanism 3 pushes the tubular container 100 into the positioning and clamping carrier 2, and then the conveying mechanism 1 transports the positioning and clamping carrier 2 to each station. When the positioning and clamping carrier 2 arrives at the first filter feeding mechanism 5, the first filter feeding mechanism 5 loads the first filter 12 into the lower end of the tubular container 100. The positioning and clamping carrier 2 is then transported to the first blocking mechanism 6, which has a first blocking part 1001 at the bottom of the tubular container 100 to prevent the first filter 12 from coming out of the lower end of the tubular container 100. The positioning and clamping carrier 2 is then transported to the filling mechanism 7, which fills the granular medicine. The second filter 13 is filled into the tubular container 100; the positioning and clamping carrier 2 is conveyed to the second filter feeding mechanism 9, which loads the second filter 13 into the upper end of the tubular container 100; the positioning and clamping carrier 2 is conveyed to the second blocking mechanism 10, which provides a second blocking part 1002 at the top of the tubular container 100 to prevent the second filter 13 from coming out of the upper end of the tubular container 100; the positioning and clamping carrier 2 is conveyed to the tubular container unloading mechanism 11, which moves the tubular container 100 with completed drug filling from the positioning and clamping carrier 2 onto the unloading conveyor belt.

[0033] Specifically, the conveying mechanism 1 is a magnetic levitation conveyor line. The magnetic levitation conveyor line can transport each positioning clamping carrier 2 individually, that is, it can transport the positioning clamping carrier 2 to different workstations for assembly. For example, when the magnetic levitation conveyor line transports one positioning clamping carrier 2 to the tubular container feeding mechanism 3 for feeding, it can also transport another positioning clamping carrier 2 to the filling mechanism 7 for filling, or transport a third positioning clamping carrier 2 to the first blocking mechanism 6 for bottom fusion.

[0034] As another embodiment of the present invention: a first aligning mechanism 4 is provided between the tubular container feeding mechanism 3 and the first filter feeding mechanism 5 to align the lower end of the tubular container 100. The first aligning mechanism 4 is used to align the lower end of the tubular container 100 to facilitate the subsequent insertion of the first filter 12 into the lower end of the tubular container 100.

[0035] Specifically, the first filter feeding mechanism 5 loads the first filter 12 into the lower end of the tubular container 100 from bottom to top, and the first filter 12 is inserted into the tubular container 100.

[0036] As another embodiment of the present invention: a second aligning mechanism 8 is provided between the filling mechanism 7 and the second filter feeding mechanism 9 to align the upper end of the tubular container 100. The second aligning mechanism 8 is used to align the upper end of the tubular container 100 so as to facilitate the subsequent insertion of the second filter 13 into the upper end of the tubular container 100.

[0037] Specifically, the second filter feeding mechanism 9 loads the second filter 13 into the upper end of the tubular container 100 from top to bottom, and the second filter 13 is inserted into the tubular container 100.

[0038] In another embodiment of the present invention, the first blocking mechanism 6 is used to roll the bottom opening of the tubular container 100 inward to form a first blocking part 1001. The first blocking mechanism 6 forms the first blocking part 1001 by heat-melting the rolling edge of the tubular container 100. The diameter of the first filter 12 is much larger than the inner diameter of the first blocking part 1001. Therefore, the first blocking part 1001 can prevent the first filter 12 from coming out of the bottom of the tubular container 100. The heat-melting rolling method does not require additional accessories, which saves costs and has a good blocking effect. Of course, a limiting ring can also be inserted into the first blocking mechanism 6, and then the limiting ring can be fixed in the tubular container 100 by bonding or other means.

[0039] In another embodiment of the present invention, the second blocking mechanism 10 is used to roll the top end of the tubular container 100 inward to form a second blocking part 1002. The second blocking mechanism 10 forms the second blocking part 1002 by heat melting the tube opening of the tubular container 100. The diameter of the second filter 13 is much larger than the inner diameter of the second blocking part 1002. Therefore, the second blocking part 1002 can prevent the second filter 13 from coming out from the bottom of the tubular container 100.

[0040] Specifically, the structure of the second filter 13 is the same as that of the first filter 12. Both the second filter 13 and the first filter 12 allow water to pass through, but not the granular medicine. When taking the medicine, the tubular container 100 is placed in water, and the water enters along the first filter 12 to dissolve the granular medicine. Then, the medicine is inhaled.

[0041] As another embodiment of the present invention: there are two first filter feeding mechanisms 5 between the first leveling mechanism 4 and the first blocking mechanism 6. The two first filter feeding mechanisms 5 load two sets of first filters 12 into a row of tubular containers 100 on two positioning clamping carriers 2 respectively. The two first filter feeding mechanisms 5 together complete the assembly of the first filters 12 in the tubular containers 100 on one positioning clamping carrier 2. This arrangement enables the two first filter feeding mechanisms 5 to assemble the filters at the same time, which can effectively improve production efficiency.

[0042] As another embodiment of the present invention: there are two second filter feeding mechanisms 9 between the second flushing mechanism 8 and the second blocking mechanism 10. The two second filter feeding mechanisms 9 load two sets of second filters 13 into a row of tubular containers 100 on two positioning clamping carriers 2 respectively. The two second filter feeding mechanisms 9 together complete the assembly of the second filters 13 in the tubular containers 100 on one positioning clamping carrier 2. This arrangement enables the two second filter feeding mechanisms 9 to assemble the filters at the same time, which can effectively improve production efficiency.

[0043] As another embodiment of the present invention: there are two filling mechanisms 7 between the first blocking mechanism 6 and the second flushing mechanism 8, and the two filling mechanisms 7 can respectively fill different granular drugs into the tubular container 100.

[0044] As another embodiment of the present invention: refer to the appendix Figure 4 The positioning clamping carrier 2 is provided with multiple clamping slots 200 for clamping tubular containers 100. The multiple clamping slots 200 are divided into two rows, and the two rows of clamping slots 200 are staggered. This arrangement makes the structure of the positioning clamping carrier 2 more compact, or, in the case of the same length, the staggered two rows of clamping slots 200 can transport more tubular containers 100.

[0045] As another embodiment of the present invention: the tubular container feeding mechanism 3 is used to push two rows of tubular containers 100 into the clamping slots 200 on the two positioning clamping carriers 2 respectively. After the two rows are clamped into the clamping slots 200 on the positioning clamping carriers 2, the two rows of tubular containers 100 on the two positioning clamping carriers 2 are staggered. That is, the tubular container feeding mechanism 3 feeds the two rows of tubular containers 100 into the two positioning clamping carriers 2 at the same time through staggered feeding.

[0046] In another embodiment of the present invention: the tubular container unloading mechanism 11 takes the assembled tubular container 100 out of the positioning clamping carrier 2, and then flips the tubular container 100 into a horizontal state and places it on the unloading conveyor belt.

[0047] Specifically, the magnetic levitation conveyor line is a ring-shaped conveyor belt consisting of two straight segments and two curved segments.

[0048] See attached document Figure 5 The present invention also provides a method for producing an oral straw formulation, comprising the following steps:

[0049] S1. Loading: The tubular container 100 is conveyed to the positioning clamping carrier 2 on the conveying mechanism 1, and the tubular container 100 in the positioning clamping carrier 2 is in a vertical state. The magnetic levitation conveyor line moves one positioning clamping carrier 2 to the tubular container loading mechanism 3 each time, and the tubular container loading mechanism 3 sends the tubular container 100 into the positioning clamping carrier 2 in a vertical state. Specifically, the tubular container loading mechanism 3 sucks up the tubular container 100 by vacuuming, then flips it into a vertical state, and finally sends it into the positioning clamping carrier 2. For example, the tubular container loading mechanism 3 sucks up the tubular container 100 through a suction nozzle, then flips it into a vertical state and sends it into the positioning clamping carrier 2.

[0050] S2. First filter assembly: The magnetic levitation conveyor line transports the positioning clamping carrier 2 to the first filter feeding mechanism 5, and the first filter feeding mechanism 5 pushes the first filter 12 upward into the tubular container 100.

[0051] S3, Fusion: The magnetic levitation conveyor line transports the positioning clamping carrier 2 to the first blocking mechanism 6. The first blocking mechanism 6 heats the tube opening at the bottom of the tubular container 100 to form the first blocking part 1001. The inner diameter of the first plug part is smaller than the outer diameter of the first filter 12, which can prevent the first filter 12 from falling out of the tubular container 100.

[0052] S4, Drug filling: The magnetic levitation conveyor line transports the positioning clamping carrier 2 to the filling mechanism 7, and the filling mechanism 7 fills the drug into the tubular container 100 of the positioning clamping carrier 2.

[0053] S5. Second filter assembly: The magnetic levitation conveyor line transports the positioning clamping carrier 2 to the second filter feeding mechanism 9, and the second filter feeding mechanism 9 presses the second filter 13 downward into the tubular container 100.

[0054] S6, Fusion: The magnetic levitation conveyor line transports the positioning clamping carrier 2 to the second blocking mechanism 10. The second blocking mechanism 10 heat-melts the opening at the top of the tubular container 100 to form a second blocking part 1002. The inner diameter of the second block part is smaller than the outer diameter of the second filter 13, which can prevent the second filter 13 from coming out of the tubular container 100.

[0055] S7. Unloading: The magnetic levitation conveyor line transports the positioning clamping carrier 2 to the tubular container unloading mechanism 11. The tubular container unloading mechanism 11 takes the oral straw preparation made in the above steps out of the positioning clamping carrier 2, and then flips the oral straw preparation into a horizontal state and places it on the unloading conveyor belt.

[0056] The feeding step and the first filter assembly step also include a step of aligning the bottom of the tubular container 100: in this step, the tubular container 100 is arranged so that the bottom of the tubular container 100 is aligned.

[0057] Between the second filter assembly step and the fusion step, there is also a step of aligning the top of the tubular container 100: in this step, the tubular container 100 is arranged so that the top of the tubular container 100 is aligned.

[0058] In another embodiment of the present invention: the positioning clamping carrier 2 is provided with two rows of clamping slots 200 for clamping tubular containers 100. The two rows of clamping slots 200 are staggered, and each row of clamping slots 200 clamps one set of tubular containers 100. One positioning clamping carrier 2 will transport two sets of tubular containers 100 for the assembly of oral straw preparations. After the magnetic levitation conveyor line has transported one positioning clamping carrier 2, the production of two rows of oral straw preparations can be completed. This setting can effectively improve the assembly efficiency of oral straw preparations. The production of two rows of oral straw preparations is as follows:

[0059] In the feeding process: the tubular container feeding mechanism 3 pushes two rows of tubular containers 100 into the clamping slots 200 of the two positioning clamping carriers 2 each time. The first row of clamping slots 200 of one positioning clamping carrier 2 holds one row of tubular containers 100, while the second row of clamping slots 200 of the other positioning clamping carrier 2 holds the other row of tubular containers 100. Specifically, the tubular container feeding mechanism 3 pushes two rows of tubular containers 100 into the two positioning clamping carriers 2, and then the magnetic levitation conveyor line moves the rear positioning clamping carrier 2 to the position of the front positioning clamping carrier 2. The tubular container feeding mechanism 3 then pushes two rows of tubular containers 100 into the two positioning clamping carriers 2 again, repeating the above steps to achieve staggered feeding. For example, four positioning and clamping carriers 2 (a, b, c, d) and a tubular container feeding mechanism 3 push two rows of tubular containers 100 into a and b. The magnetic levitation conveyor line moves c to position b, and the tubular container feeding mechanism 3 pushes two rows of tubular containers 100 into b and c. At this time, b clamps two rows of tubular containers 100. The magnetic levitation conveyor line moves d to position c, and the tubular container feeding mechanism 3 pushes two rows of tubular containers 100 into c and d. At this time, c clamps two rows of tubular containers 100, thus achieving staggered feeding.

[0060] When the positioning clamping carrier 2 clamps two rows of staggered tubular containers 100, one way to assemble the first filter is as follows: two first filter feeding mechanisms 5 are distributed sequentially along the magnetic levitation conveyor line. One first filter feeding mechanism 5 loads the first filter 12 into the lower end of one row of tubular containers 100 of the positioning clamping carrier 2. Then the magnetic levitation conveyor line transports the positioning clamping carrier 2 to the other first filter feeding mechanism 5, and the other first filter feeding mechanism 5 assembles the first filter 12 onto the other row of tubular containers 100 of the positioning clamping carrier 2.

[0061] When the positioning and clamping carrier 2 clamps two rows of staggered tubular containers 100, one way to achieve drug filling is as follows: two filling mechanisms 7 are distributed sequentially along the magnetic levitation conveyor line. One filling mechanism 7 fills the granular drug into one row of tubular containers 100 of the positioning and clamping carrier 2. Then, the magnetic levitation conveyor line transports the positioning and clamping carrier 2 to the other filling mechanism 7, and the other filling mechanism 7 fills the granular drug into the other row of tubular containers 100 of the positioning and clamping carrier 2.

[0062] When the positioning clamping carrier 2 clamps two rows of staggered tubular containers 100, one way to assemble the second filter is as follows: two second filter feeding mechanisms 9 are distributed sequentially along the magnetic levitation conveyor line. One second filter feeding mechanism 9 loads the second filter 13 into the lower end of one row of tubular containers 100 of the positioning clamping carrier 2. Then, the magnetic levitation conveyor line transports the positioning clamping carrier 2 to the other second filter feeding mechanism 9, and the other second filter feeding mechanism 9 assembles the second filter 13 onto the other row of tubular containers 100 of the positioning clamping carrier 2.

[0063] In this invention, the conveying mechanism 1 sequentially conveys the positioning and clamping carrier 2 to the tubular container feeding mechanism 3, the first filter feeding mechanism 5, the first blocking mechanism 6, the filling mechanism 7, the second filter feeding mechanism 9, the second blocking mechanism 10, and the tubular container unloading mechanism 11. The tubular container feeding mechanism 3 conveys the tubular container 100 into the positioning and clamping carrier 2. The second aligning mechanism 8 aligns the tubular container 100 on the positioning and clamping carrier 2, ensuring its bottom is aligned. The first filter feeding mechanism 5 loads the first filter 12 into the tubular container 100 on the positioning and clamping carrier 2. At the lower end, the first blocking mechanism 6 provides a first blocking part 1001 at the lower end of the tubular container 100 to prevent the first filter 12 from coming out. The filling mechanism 7 fills the granular medicine into the tubular container 100. The second filter feeding mechanism 9 loads the second filter 13 onto the upper end of the tubular container 100 on the positioning clamping carrier 2. The second blocking mechanism 10 provides a first blocking part 1001 at the upper end of the tubular container 100 to prevent the second filter 13 from coming out. Finally, the tubular container 100 that has been filled on the positioning clamping carrier 2 is transferred to the unloading conveyor belt by the tubular container unloading mechanism 11. This invention realizes the automated assembly of a tubular container 100 with two filters, one above and one below, with high production efficiency. Secondly, the bottom fusion crimping and top fusion crimping can better prevent the filter from coming out of the tubular container 100, avoiding the possibility of the filter falling off due to scratches. The filter will not fall off due to the production process, which helps to ensure the quality of oral straw preparations.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
