Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine granule packaging equipment, and particularly relates to an automatic blanking and sealing device for traditional Chinese medicine granules. Background Art

[0002] Traditional Chinese medicine culture in China has a long history and rich resources. However, currently, China only accounts for a small part of the global export volume of traditional Chinese medicine. The main reason is that China still uses the primitive method of dispensing raw herbs by hand and weighing them. During the process of dispensing traditional Chinese medicine, the speed is slow, the measurement error is large, and it is difficult to connect with the international market that requires standardization, standardization, and scientific management of medicine dispensing.

[0003] With the development of technology, some hospitals have started to use mechanical automatic medicine dispensing. To meet the needs of mechanized medicine dispensing, existing medicine dispensing machines use medicine boxes with fixed shapes. After traditional Chinese medicine is loaded into the medicine box, the surface of the medicine box is sealed with a plastic film. However, the medicine box takes up a large amount of space, has a high cost, and is inconvenient to carry. If the bagged packaging method can be used, it can save costs and is convenient to carry.

[0004] A continuous metering and blanking device for traditional Chinese medicine granules with the publication number CN205045020 discloses a structure of a medicine bottle and a blanking port. The medicine bottle is driven by the blanking port to quantitatively drop the traditional Chinese medicine granules in the medicine bottle into the medicine box below it. With the blanking port and the medicine bottle of the above structure, the quantitative blanking function of the medicine box can be realized. However, if the medicine box is replaced with a medicine bag, since the opening area of the medicine bag is small and the opening shape is difficult to control, it is necessary to redesign the medicine bag control mechanism to cooperate with the above blanking device to keep the opening all the time during the blanking process and complete automatic blanking.

[0005] In addition, since the packaging bag is easy to deform and its shape is difficult to control, and the dosage fluctuations of different prescriptions are large, after traditional Chinese medicine granules are loaded into the medicine bag, the opening shape of the medicine bag and the proportion of traditional Chinese medicine granules in the capacity of the packaging bag will have a great impact on the sealing quality of the medicine bag.

[0056] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0057] Combined with Figures 1 - 3 , an automatic feeding and sealing device for traditional Chinese medicine granules according to an embodiment of the present invention includes a feeding mechanism 100, a medicine bag control mechanism 200 and a medicine bag sealing mechanism 300;

[0058] The feeding mechanism 100 includes a feeding port 101 and a medicine bottle, and is used for quantitatively pouring the medicines contained in different medicine bottles into the medicine bags below the feeding port 101 through the feeding port 101;

[0059] The medicine bag control mechanism 200 includes a turntable moving mechanism 1 and a turntable 2 provided on the turntable moving mechanism 1, and the turntable moving mechanism 1 can drive the turntable 2 to move;

[0060] The turntable 2 includes a dosing tray rotating mechanism 21, a dosing tray 22 and a fixing frame 23, the dosing tray 22 is provided on the dosing tray rotating mechanism 21, and a plurality of the fixing frames 23 are provided on the dosing tray 22; the fixing frame 23 is used for carrying medicine bags;

[0061] The medicine bag sealing mechanism 300 includes a sealing component for sealing traditional Chinese medicine in bags, a displacement component for driving the sealing component to translate, and a jacking component for driving the traditional Chinese medicine in bags to lift;

[0062] The medicine bag control mechanism 200 can drive the medicine bag to move, so that the medicine bag is directly below the feeding port 101 and moves to the medicine bag sealing mechanism 300.

[0063] It should be noted that the meaning of traditional Chinese medicine in bags refers to the medicine bags that have completed feeding, including the medicine bags and the traditional Chinese medicine inside the medicine bags.

[0064] The present invention moves the turntable 2 through the turntable moving mechanism 1 to realize the switching of the turntable 2 between different working stations; a plurality of fixing frames 23 are provided on the turntable 2, which can fix the medicine bags, so as to realize the functions of receiving bags at the bag-making station, feeding at the feeding station and sealing at the sealing station. Different working stations can work simultaneously, and the dispensing efficiency is high.

[0065] Through a specially designed fixing rack 23, the medicine bag can be fixed while keeping its opening open. After the medicine bag is placed in the fixing rack 23, it can be transferred to the blanking station for blanking, without the need for an additional spreading step, simplifying the structure of the blanking mechanism 100 and also avoiding possible contamination of the medicine bag caused by using tools to open the bag mouth. Through the above structure, the multi-station automatic blanking and sealing functions of the medicine can be realized, meeting the requirements of automatic medicine dispensing in the pharmacy.

[0066] Among them, the medicine bottles containing different traditional Chinese medicine granules are arranged on a shelf on one side of the automatic blanking and sealing device for traditional Chinese medicine granules, similar to the arrangement of a traditional Chinese medicine cabinet. When blanking is required, the dispensing personnel can manually take the corresponding medicine bottle and put it into the blanking port 101, and add a predetermined amount of traditional Chinese medicine granules into the medicine bag. Preferably, in order to improve the blanking accuracy and automation level, the medicine bottle can adopt an existing special medicine bottle with an automatic weighing mechanism, and the blanking port 101 is provided with an automatic weighing mechanism driving device. When the automatic weighing mechanism of the medicine bottle extends into the blanking port 101, the automatic weighing mechanism driving device will drive the automatic weighing mechanism to measure a predetermined weight of traditional Chinese medicine granules in the medicine bottle, and then fall into the medicine bag directly below it by gravity.

[0067] The turntable moving mechanism 1 of the multi-station medicine bag control device is used to drive the turntable 2 to move, facilitating the switching of the turntable 2 between different stations, enabling the simultaneous progress of the bagging, blanking, and sealing processes, thereby improving the medicine dispensing efficiency. The turntable moving mechanism 1 can drive the turntable 2 to move linearly or drive the turntable 2 to rotate, which is specifically set according to actual needs. In this embodiment, the turntable moving mechanism 1 drives the turntable to rotate.

[0068] According to a specific embodiment of the present invention, in combination with Figures 4 - 6 , the turntable moving mechanism 1 includes a turntable rotating mechanism 11 and a turntable mounting member 12 connected to the turntable rotating mechanism 11. The turntable rotating mechanism 11 is used to drive the turntable mounting member 12 to rotate, thereby realizing the switching of the turntable 2 between different stations. It includes a turntable motor 111, a turntable synchronous belt 112 connected to the turntable motor 111, and a turntable gear 113 connected to the turntable synchronous belt 112. Among them, the turntable gear 113 is fixedly connected to the turntable mounting member 12. Therefore, when the turntable motor 111 works, it drives the turntable synchronous belt 112 and the turntable gear 113 to move, and the turntable gear 113 drives the turntable mounting member 12 to rotate, thereby realizing the rotation of the turntable mounting member 12.

[0069] Preferably, at least two turntable mounting positions are provided on the turntable mounting member 12, and the turntable 2 is mounted on the turntable mounting positions. Therefore, when the turntable mounting member rotates, the turntable 2 is driven to move together, so that the turntable 2 can be switched between different workstations.

[0070] The turntable 2 is arranged on the turntable mounting member of the turntable moving mechanism 1, and its number is preferably at least two, which is convenient for realizing synchronous operation of at least two processes and improving the medicine dispensing efficiency. In this embodiment, the turntable 2 includes a dosing tray rotating mechanism 21, a dosing tray 22 arranged on the dosing tray rotating mechanism 21, and a plurality of fixing frames 23 arranged on the dosing tray 22. The dosing tray rotating mechanism 21 is used to drive the dosing tray 22 to rotate to ensure that a plurality of medicine bags can complete the operations of corresponding processes in sequence.

[0071] Specifically, as Figure 7 shown, the dosing tray rotating mechanism 21 includes a dosing tray motor 211, a dosing tray synchronous belt 212 connected to the dosing tray motor 211, and a dosing tray gear 213 connected to the dosing tray synchronous belt 212. Among them, the dosing tray gear 213 is connected to the dosing tray 22. Therefore, when the dosing tray motor 211 works, the dosing tray synchronous belt and the dosing tray gear rotate under the action of the dosing tray motor, thereby driving the dosing tray 22 to rotate.

[0072] The dosing tray 22 is circular, and a plurality of mounting openings 24 are provided thereon. The plurality of mounting openings 24 are evenly distributed along the circumferential direction of the dosing tray 22. The fixing frames 23 are fixed to the dosing tray 22 through the mounting openings 24, so that the fixing frames 23 can be evenly distributed in the circumferential direction of the dosing tray 22, which is convenient for mechanized control.

[0073] Specifically, the mounting opening 24 has an axisymmetric structure, and its shape and size are adapted to the shape and size of the fixing frame 23. It includes an outwardly curved arc structure and a U-shaped structure connected to the arc structure. The U-shaped structure is located at both ends of the arc structure.

[0074] As Figure 8 shown, in order to facilitate blanking and improve the blanking efficiency, the mounting opening 24 is inclined on the dosing tray 22. Specifically, the center line of the U-shaped structure of the mounting opening 24 forms an intersection with the edge of the dosing tray 22, and the angle a between the tangent line passing through this intersection and this center line, the angle a > 0° and < 90°. Preferably, the angle a is 10° - 60°, so that the blanking mechanism 100 can better align with the fixing frame, which is convenient for blanking and improves the distribution density of the mounting openings at the same time.

[0075] As Figures 9 - 10As shown, the fixing bracket 23 is arranged inside the installation opening 24, and its shape and size match those of the installation opening, facilitating the placement of multiple medicine bags, thereby enabling multiple medicine bags to sequentially complete corresponding operations. In this embodiment, the fixing bracket 23 includes a main body 231, a first opening 232 provided at the top of the main body 231, a receiving cavity 233 provided inside the main body 231 and communicating with the first opening 232, and a second opening 234 provided at the bottom of the main body 231. The receiving cavity 233 includes a medicine bag cavity 23a for receiving medicine bags and a positioning cavity 23b. The positioning cavity 23b is provided at both ends of the medicine bag cavity 23a and communicates with the medicine bag cavity 23a.

[0076] Among them, the width of the medicine bag cavity 23a gradually decreases from the top to the bottom, and the width of the central region on the same horizontal plane is greater than that of its two sides; the width of the positioning cavity 23b is equal to the minimum width of the medicine bag cavity 23a, and both sides of the medicine bag extend into the positioning cavity 23b.

[0077] The shape and size of the first opening 232 match those of the installation opening 24, and it is embedded inside the installation opening 24. To facilitate the detachable connection between the fixing bracket 23 and the batching tray 22 and for easy cleaning, etc., a fixing strip 235 extending outward is provided at the edge of the first opening 232. During installation, the fixing strip 235 abuts against the upper surface of the batching tray 22, thereby realizing the connection between the fixing bracket 23 and the batching tray 22, which is convenient and quick to disassemble and assemble and easy to maintain.

[0078] The second opening 234 extends upward from the bottom of the main body 231, causing two fixing feet 236 to be formed at the bottom of the main body 231 for supporting the main body 231 and the medicine bags, ensuring that an external mechanism can smoothly apply force to or detect the medicine bags and ensuring the smooth progress of the medicine dispensing process.

[0079] Combined with Figure 11 and Figure 12, the medicine bag sealing mechanism 300 includes a sealing component 3 for sealing traditional Chinese medicine in bags, a displacement component 4 for driving the sealing component 3 to translate, and a lifting component 5 for driving the bagged traditional Chinese medicine to lift; the sealing component 3 includes a first guide rail 31, a first slider 32, a second slider 33, a first heating block 34, a second heating block 35, and a slider driving mechanism 36; the first slider 32 and the second slider 33 are arranged on the first guide rail 31; the first heating block 34 is arranged on the first slider 32, and the second heating block 35 is arranged on the second slider 33; the slider driving mechanism 36 is used to drive the first slider 32 and the second slider 33 to slide towards each other along the first guide rail 31; the lifting component 5 includes a lifting block 51 and a lifting block driving mechanism 52, and a bayonet 511 is arranged at the upper end of the lifting block 51. Preferably, the cross-section of the bayonet 511 is V-shaped. The lifting block driving mechanism 52 is used to drive the lifting block 51 to move up and down.

[0080] With the medicine bag sealing mechanism 300, the lifting component 5 can support the bottom of the packaging bag and push it upwards. The bayonet 511 positions the medicine bag during the upward movement of the packaging bag, preventing the medicine bag from rotating and ensuring the same orientation when the medicine bag is sealed. The first heating block 34 and the second heating block 35 move towards each other under the drive of the first slider 32 and the second slider 33, and can gradually press the bag mouth towards its center, and tightly fit through the hot melting method to ensure the sealing quality.

[0081] Combined Figure 13 As shown, the lifting block driving mechanism 52 includes a lifting rod 521, a linear bearing 522, a synchronous belt 523, and a third motor 524. The lifting rod 521 is sleeved in the linear bearing 522, and the top is connected to the lifting block 51; the lower part of the lifting rod 521 is connected to the synchronous belt 523, and the third motor 524 drives the synchronous belt 523 to move, so as to drive the lifting rod 521 to extend or retract vertically.

[0082] Since there is a certain amount of movement space for the whole packaging bag after being lifted by the lifting component 5, which makes the position of the bag mouth change within a certain range. Therefore, the first heating block 34 and the second heating block 35 must be able to approach each other sensitively and quickly, straighten the bag mouth and gradually compress it until it is completely fitted. For this reason, the present application designs a special slider driving mechanism 36. As Figure 12As shown in the figure, the slider driving mechanism 36 includes a slider fixing frame 361, a first motor 362, a crank 363, a linkage 364, a first spherical bearing 365 and a second spherical bearing 366; the linkage 364 is hinged to the slider fixing frame 361 through a hinge point 369, and is connected to the first slider 32 through the first spherical bearing 365 and to the second slider 33 through the second spherical bearing 366; a chute 367 is further provided on the linkage 364, and a needle roller bearing 368 is provided at one end of the crank 363, and the needle roller bearing 368 is arranged in the chute 367. The needle roller bearing 368 can slide in the chute 367; the first motor 362 can drive the linkage 364 to rotate through the crank 363, so as to drive the first slider 32 and the second slider 33 to move towards each other. Usually, the specifications of the first spherical bearing 365 and the second spherical bearing 366 are the same, and the connection positions with the linkage 364 should be on the circumference with the same diameter as the hinge point of the linkage 364 and the slider fixing frame 361, so as to realize the same-speed movement of the first slider 32 and the second slider 33.

[0083] As mentioned above, since the weight of the traditional Chinese medicine granules loaded into the above-mentioned traditional Chinese medicine granule packaging bag each time is different, the space remaining at the bag mouth before sealing the medicine bag also varies greatly. For example, sometimes the traditional Chinese medicine granules only occupy one-third of the space of the medicine bag, and sometimes they occupy three-quarters. If a simple sealing technology is adopted for different loading ratios, in the case of a small loading amount, the medicine bag is likely to contain too much air, which is likely to affect the shelf life of the medicine, and the bulging medicine bag is also likely to be damaged due to pressure; in the case of a large loading amount, the traditional Chinese medicine granules are likely to run to the sealing position, affecting the sealing reliability. Therefore, in this embodiment, a first shaping member is further provided on the first slider 32, and a second shaping member is further provided on the second slider 33. The first shaping member includes a side plate 37 and a first pressing plate 38, and the side plate 37 extends from both sides of the front surface of the first pressing plate 38; the second shaping member includes a second pressing plate 39, and the first pressing plate 38 and the second pressing plate 39 are arranged opposite to each other. The side plate 37 contacts both sides of the bag mouth to straighten the bag mouth. During the sealing process, the first pressing plate 38 and the second pressing plate 39 abut against the first heating block 34 and the second heating block 35 first; the air in the packaging bag is pressed out. If there are already traditional Chinese medicine granules at the pressing position, they will be gradually tightened upwards, and the traditional Chinese medicine granules will be slightly pressed downwards during the process of pressing the opening. After the sealing is completed, the first heating block 34 and the second heating block 35 separate from the first pressing plate 38 and the second pressing plate 39 first, and the first pressing plate 38 and the second pressing plate 39 fix the medicine bag to prevent the medicine bag from adhering to the first heating block 34 or the second heating block 35, which is convenient for automatic discharging.

[0084] After the sealing is completed, through the displacement assembly 4, the medicine bag is driven to translate and move to the discharge port to realize automatic discharging. Combined withFigure 14 As shown, the displacement assembly 4 includes a second guide rail 41, a translation slider 42, a translation fixed seat 43, and a translation slider driving mechanism 44; the second guide rail 41 is installed on the translation fixed seat 43; the translation slider driving mechanism 44 is used to drive the translation slider 42 to move along the second guide rail 41; the translation slider 42 is connected to the slider fixing bracket 361. The translation slider driving mechanism 44 can be a cylinder, a linear motor capable of driving the translation slider 42 to reciprocate linearly, or a swing rod mechanism 46 driven by a motor 45, etc.

[0085] Preferably, in order to avoid rigid collisions when the first heating block 34 and the second heating block 35, the first pressing plate 38 and the second pressing plate 39 approach each other, the first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 are all connected to an elastic buffer mechanism (not shown in the figure). Specifically, the elastic buffer mechanism can be a spring. The first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 are all connected to the first slider 32 or the second slider 33 through corresponding guide posts, and springs are sleeved outside the guide posts. The first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 are connected to the corresponding first slider 32 or the second slider 33 through the springs, so that the first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 have a certain buffer space when encountering resistance.

[0086] The working principle of this embodiment is as follows:

[0087] The bag-making mechanism places the made medicine bags inside the fixing bracket 23. The batching tray 22 rotates to the position of one mounting opening, and then places new medicine bags inside the next fixing bracket 23 until the preset number of medicine bags are loaded. The turntable rotation mechanism 11 drives the turntable 2 to rotate until the batching tray 22 with medicine bags is located below the feeding mechanism 100. The feeding mechanism 100 has an automatic quantitative feeding function and can inject a preset weight of medicine into the medicine bags. After the feeding of one medicine bag is completed, the batching tray rotation mechanism 21 drives the batching tray 22 to rotate to the position of one mounting opening 24 to feed the next medicine bag until the preset number of medicine bags are loaded.

[0088] After the medicine bag is filled with Chinese medicinal granules, the turntable rotation mechanism 11 drives the turntable 2 to rotate again, coordinating with the rotation of the ingredient tray 22, and delivering the medicine bag currently in need of sealing to the top of the lifting assembly 5, which is directly opposite the sealing assembly 3. At this time, the lifting assembly 5 drives the lifting block 51 to rise. The latter, through its latch 511, presses against the bottom of the medicine bag and ejects it upward from the fixed frame 23. During the ejection process, the positioning cavity 23b of the fixed frame 23 continuously guides the medicine bag until it is lifted to the predetermined position of the sealing assembly 3. Subsequently, the slider drive mechanism 36 drives the first slider 32 and the second slider 33 to move toward each other, and the sealing action begins. During the sealing process, the side plates 37 first contact the medicine bag, gently contacting both sides of the medicine bag to prevent it from tilting. Then, the first and second compression plates 38, 39 begin to contact the center height of the medicine bag and gradually compress it toward each other. If Chinese medicine granules are already contained at the compression position, the first and second compression plates 38, 39 have elastic margins, and the compression surfaces of the first and second compression plates 38, 39 are slightly tilted, causing the medicine bag to form a central bulge and gradually fit from the center to the opening. Finally, the first and second heating blocks 34, 35 compress and heat the predetermined sealing position near the opening of the medicine bag to complete the sealing process. After sealing is completed, the displacement assembly 4 drives the sealing assembly 3 to translate as a whole, driving the medicine bag to the discharge station. Then, the first and second sliders 32, 33 move away from each other, and the first and second heating blocks 34, 35 are first separated from the medicine bag. Then, the first and second compression plates 38, 39 separate from the medicine bag, and the medicine bag falls into the discharge station due to gravity. The discharge station can be a simple discharge port, from which the operator manually takes the sealed medicine bags; or it can be a discharge conveyor line, through which the sealed medicine bags are transported to a predetermined temporary storage location and discharged after all packaging is completed.

[0089] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
