Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical production technology, specifically relating to a method for dispensing traditional Chinese medicine decoction pieces, and also to a system for dispensing traditional Chinese medicine decoction pieces to implement this dispensing method. Background Technology

[0002] In the production process of traditional Chinese medicine (TCM), a set amount of medicinal herbs needs to be mixed and decocted together according to a predetermined dosage to form a TCM preparation. Weighing the prescribed weight of medicinal herbs according to the TCM formula is called dispensing. To improve the production efficiency and automation of TCM, a TCM decoction dispensing mechanism has been designed to achieve automatic dispensing of TCM decoction herbs.

[0003] However, existing Chinese herbal medicine dispensing facilities all use a method of dispensing and weighing the herbs one at a time. Due to the varying shapes and sizes of Chinese herbal medicine pieces, their overlapping and complex adhesion, overweight issues are prone to occur during dispensing. If overweight occurs during machine dispensing, all the Chinese herbal medicine pieces in the weighing hopper need to be emptied and re-weighed, resulting in a large quantity of Chinese herbal medicine pieces requiring repeated weighing during dispensing.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method for dispensing Chinese herbal medicine slices. By setting both an automatic dispensing stage and a manual dispensing stage in the dispensing process, the Chinese herbal medicine slices output by the automatic dispensing stage can have their overweight parts removed manually. This overcomes the problem of the existing technology that requires repeated feeding and weighing of overweight Chinese herbal medicine slices, which causes serious damage to the Chinese herbal medicine slices.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A method for dispensing traditional Chinese medicine decoction pieces includes an automatic dispensing stage and a manual dispensing stage. The dispensing method includes the following steps:

[0008] When the actual amount of medicine dispensed during the automatic dispensing phase exceeds the expected amount, the excess amount can be removed during the manual dispensing phase.

[0009] Furthermore, when the actual amount of a certain herb dispensed during the automatic dispensing stage exceeds the expected amount, the conveying device will send a separate transfer box to receive and transport that portion of the Chinese herbal medicine pieces separately.

[0010] Furthermore, before the manual dispensing stage, the weight of the Chinese herbal medicine pieces in the turnover box is checked to determine whether the error between the actual amount of medicine dispensed and the expected amount of medicine dispensed meets the accuracy requirements.

[0011] During the manual dispensing stage, some Chinese herbal medicine pieces that do not meet the dispensing accuracy requirements in the turnover box are removed.

[0012] Furthermore, during the automatic dispensing stage, the actual amount of Chinese herbal medicine pieces that meet the accuracy requirements of the expected amount of dispensing are received and transferred by the conveying device to the medicine frame. The medicine frame will receive and transfer all the required Chinese herbal medicine pieces one by one according to the requirements of the Chinese herbal medicine formula to complete the entire dispensing work.

[0013] Furthermore, during the automatic dispensing stage, multiple Chinese herbal medicine pieces within the same Chinese medicine formula, whose actual dispensing amount meets the expected dispensing amount accuracy, are received and transported by the same medicine frame;

[0014] It also includes a review stage, in which the Chinese herbal medicine pieces from the manual dispensing stage are added to the corresponding medicine boxes according to the Chinese herbal medicine prescription.

[0015] Furthermore, in the automatic dispensing stage, the dispensing unit dispenses the medication, and the dispensing speed of the dispensing unit gradually slows down as the difference between the actual amount of medication dispensed and the expected amount of medication dispensed decreases.

[0016] Furthermore, the dispensing unit stores multiple adjustment levels from fast to slow. As the difference between the actual amount of medicine dispensed and the expected amount of medicine dispensed gradually decreases, the dispensing unit gradually switches from the fast level to the slow level.

[0017] Furthermore, when switching to a slower setting, if the difference between the actual and expected drug dispensing amounts increases, the dispensing unit will switch back to a faster setting corresponding to the difference between the actual and expected drug dispensing amounts at this time.

[0018] The present invention also discloses a system for implementing the above-mentioned method for dispensing Chinese herbal medicine pieces, including a conveying device carrying a medicine frame and a turnover box, and an automatic dispensing area, a manual dispensing area and a verification area arranged sequentially along the conveying direction of the conveying device. An online scale is also provided on the conveying device between the automatic dispensing area and the manual dispensing area.

[0019] Furthermore, the automatic dispensing area is equipped with several dispensing units for dispensing medicine;

[0020] The dispensing unit is located above the conveying device and arranged along the extension direction of the conveying device. The dispensing unit is modularly designed and can be combined and arranged in modules according to actual needs to meet the requirements of formula and production capacity.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0022] 1. This invention incorporates both an automatic dispensing stage and a manual dispensing stage during the dispensing process of traditional Chinese medicine (TCM) decoction pieces. By manually removing the excess weight of the TCM decoction pieces output from the automatic dispensing stage, it ensures a high degree of automation and guarantees the production efficiency of TCM. On the other hand, it also reduces the number of times TCM decoction pieces are repeatedly fed and weighed, thereby reducing the degree of damage to the TCM decoction pieces.

[0023] 2. This invention improves the accuracy of the dispensing process by setting the dispensing unit's speed to be adjustable in multiple levels and gradually slowing it down as the difference between the actual and expected dispensing amounts decreases. Furthermore, considering the impact of material drop on weighing, when the dispensing unit switches to a slower speed, if an increase in the difference between the actual and expected dispensing amounts is detected, the dispensing unit switches back to a faster speed corresponding to the current difference, achieving adaptive adjustment of the dispensing speed and improving dispensing efficiency.

[0038] Example 1

[0039] like Figures 1 to 6 As shown in the embodiment of the present invention, a method for dispensing traditional Chinese medicine decoction pieces is introduced, which includes an automatic dispensing stage, a manual dispensing stage, and a verification stage.

[0040] During the automatic dispensing stage, the dispensing unit 2 of the traditional Chinese medicine (TCM) decoction piece dispensing mechanism dispenses the medicine. The TCM decoction piece dispensing mechanism includes a support 1 and a dispensing unit 2 installed on the support 1. The conveying device 4 extends at least partially into the support 1. The dispensing unit 2 places the corresponding TCM decoction pieces onto the conveying device 4 according to the dispensing requirements, and the conveying device 4 outputs the medicine.

[0041] In this embodiment, the dispensing unit 2 includes a hopper 201, a discharge hopper 202, and a weighing hopper 204 arranged sequentially. The discharge hopper 202 connects the hopper 201 and the weighing hopper 204, conveying the Chinese herbal medicine pieces in the hopper 201 to the weighing hopper 204 for weighing. The weighing hopper 204 has a discharge port at its bottom, with a controllable door for opening and closing. The conveying device 4 is equipped with a medicine frame and a turnover box for holding the Chinese herbal medicine pieces. After being weighed by the weighing hopper 204, the Chinese herbal medicine pieces are discharged from the discharge port at the bottom of the weighing hopper 204 into the medicine frame or turnover box on the conveying device 4.

[0042] During the automatic dispensing phase, Chinese herbal medicine pieces whose actual dispensing quantity meets the accuracy requirements are carried and transported by a medicine basket; those whose actual dispensing quantity does not meet the accuracy requirements are received and transported by a turnover box. Specifically, when the control unit detects that the actual dispensing quantity equals the expected dispensing quantity, or the difference between the actual and expected dispensing quantities does not exceed the allowable error range, dispensing is stopped, and the conveying device 4 dispatches a medicine basket to receive and transport that portion of the Chinese herbal medicine pieces; when the control unit detects that the actual dispensing quantity of a certain herb is greater than the expected dispensing quantity, and the difference between the two exceeds the allowable error range, dispensing is stopped, and the conveying device 4 dispatches a turnover box to receive and transport that portion of the Chinese herbal medicine pieces separately.

[0043] In this embodiment, the manual dispensing stage involves adjusting the Chinese medicinal herbs in the turnover box. Specifically, the manual dispensing stage removes any Chinese medicinal herbs in the turnover box that exceed the expected dispensing quantity, ensuring that the remaining herbs meet the accuracy requirements. By manually removing the overweight portions of the herbs output from the automatic dispensing stage, the manual dispensing stage eliminates the need for repeated feeding and weighing of herbs exceeding the expected dispensing quantity, thus improving the integrity of the herbs. Furthermore, the manual dispensing stage only requires manipulation of the herbs in the turnover box, eliminating the need to manipulate the herbs in the medicine rack, thereby reducing the workload of workers in the manual dispensing stage.

[0044] Preferably, in this embodiment, before the manual dispensing stage, the weight of the Chinese herbal medicine in the turnover box is checked to determine the difference between the actual amount dispensed and the expected amount. That is, before the turnover box enters the manual dispensing stage, the amount of Chinese herbal medicine pieces that need to be manually removed from the turnover box has been determined. During the manual dispensing stage, workers only need to remove a fixed amount of Chinese herbal medicine pieces from the turnover box as required, further reducing the labor intensity of workers.

[0045] In this embodiment, the verification stage involves matching the medicinal herbs in the medicine boxes output from the automatic dispensing stage and the turnover boxes output from the manual dispensing stage according to the traditional Chinese medicine formula. Specifically, the conveying device 4 transports medicine boxes and / or turnover boxes containing multiple types of medicinal herbs from the same traditional Chinese medicine formula to the same verification station. The workers at this verification station then move the different types of medicinal herbs from the medicine boxes and / or turnover boxes into the same container to complete the matching.

[0046] Preferably, in this embodiment, during the automatic dispensing stage, each turnover box is only used to receive and transport one type of overweight Chinese herbal medicine slice within a Chinese herbal medicine formula; multiple Chinese herbal medicine slices within the same Chinese herbal medicine formula whose actual dispensing quantity equals the expected dispensing quantity, i.e., the error between the actual dispensing quantity and the expected dispensing quantity meets the accuracy requirements, are received and transported by the same medicine box.

[0047] In this embodiment, both the medicine basket and the turnover box are equipped with identification chips. The types and quantities of Chinese herbal medicine pieces held by the medicine basket and the turnover box are written into the identification chips. Workers in the manual dispensing stage and the verification stage can determine the information of the medicines carried in the medicine basket and the turnover box by reading the information in the identification chips.

[0048] Specifically, in the automatic dispensing stage, multiple dispensing units 2 dispense medicine according to a traditional Chinese medicine formula. A fixed quantity of medicinal herbs is transferred from the material hopper 201 to the weighing hopper 204 via the discharge hopper 202. If the actual amount of medicine dispensed from one or more weighing hoppers 204 exceeds the expected amount, the conveying device 4 dispatches one or more turnover boxes to individually receive and transfer the overweight medicinal herbs. The number of turnover boxes dispatched by the conveying device 4 is equal to the number of types of overweight medicinal herbs. The remaining different types of medicinal herbs in the formula, whose actual amount of medicine dispensed is equal to the expected amount, are received and transferred by the same medicine basket dispatched by the conveying device 4. After verification, the turnover box containing the overweight medicinal herbs enters the manual dispensing stage for adjustment. One or more turnover boxes containing overweight Chinese herbal medicine pieces from the Chinese medicine formula are simultaneously transported to the same verification station along with medicine baskets containing the remaining Chinese herbal medicine pieces from the Chinese medicine formula, with the actual amount of medicine dispensed equal to the expected amount of medicine dispensed. The workers at the verification station move all the Chinese herbal medicine pieces from the turnover boxes into the corresponding medicine baskets to complete the mixing process. Finally, the medicine baskets contain a set of Chinese medicines that meet the mixing requirements.

[0049] Example 2

[0050] In this embodiment, the automatic dispensing stage is performed by the dispensing unit 2. In order to improve the dispensing speed of the dispensing unit 2 and ensure the dispensing accuracy, the dispensing speed of the dispensing unit 2 gradually slows down as the difference between the actual amount of medicine dispensed and the expected amount of medicine dispensed decreases.

[0051] In this embodiment, the discharge hopper 202 is installed on the driver, which is electrically connected to the control unit. The control unit adjusts the working intensity of the driver according to the difference between the actual amount of medicine dispensed and the expected amount of medicine dispensed, thereby adjusting the dispensing speed and improving the dispensing accuracy.

[0052] In this embodiment, the control unit adjusts the dispensing speed of the dispensing unit 2 using a multi-level adjustment method. The control program within the dispensing unit 2 has multiple dispensing levels ranging from fast to slow. As the difference between the actual dispensing amount and the expected dispensing amount gradually decreases, the dispensing unit 2 automatically switches from the fast level to the slow level.

[0053] In this embodiment, the weighing hopper 204 is provided with a weight sensing unit for obtaining the weight of the material in the weighing hopper 204. The weight sensing unit is electrically connected to the control unit, and the weight sensing unit, the control unit and the driver adopt an adaptive adjustment mode.

[0054] Specifically, due to the impact of the falling Chinese herbal medicine pieces, the weight sensing unit inside the weighing hopper 204 experiences a certain amount of impact during the dispensing process. This causes the displayed value of the actual dispensing amount to be the sum of the true value and the impact force, meaning the displayed value of the actual dispensing amount is greater than the true value. The control unit adjusts the dispensing speed of the dispensing unit 2 based on the displayed value of the actual dispensing amount. When the dispensing speed is faster, the falling impact is greater, and the control unit controls the driver to switch from the fast gear to the slow gear at a faster speed, reducing the dispensing speed more quickly. When the dispensing speed slows down, the falling impact decreases, and the displayed value of the actual dispensing amount decreases. The control unit adjusts the dispensing speed based on this displayed value. If the difference between the displayed value of the actual dispensing amount and the expected dispensing amount increases, the control unit controls the driver to switch to the faster gear corresponding to the displayed value of the actual dispensing amount, thereby improving the dispensing efficiency of the dispensing mechanism.

[0055] Example 3

[0056] like Figures 1 to 4 and Figure 6 As shown, this embodiment discloses a traditional Chinese medicine decoction piece dispensing system. The dispensing system includes a conveying device 4 carrying a medicine frame and a turnover box, and an automatic dispensing area 7, a manual dispensing area 9 and a verification area 10 arranged sequentially along the conveying direction of the conveying device 4. An online scale 8 is also provided on the conveying device 4 between the automatic dispensing area 7 and the manual dispensing area 9.

[0057] In this embodiment, the automatic dispensing area 7 is equipped with several dispensing units 2, each of which is electrically connected to the control unit and is used to dispense medicine according to the control program; the online scale 8 is equipped with a weighing device, which is used to determine the excess amount of Chinese herbal medicine pieces in the turnover box where the actual amount dispensed exceeds the expected amount; the manual dispensing area 9 is equipped with several dispensing stations, where workers at each dispensing station remove the excess portion of Chinese herbal medicine pieces in the turnover box; the verification area 10 is equipped with several verification stations, where workers at each verification station transfer all the Chinese herbal medicine pieces from the multiple turnover boxes and / or medicine frames delivered to that station into a single container to complete the compatibility.

[0058] Example 4

[0059] like Figures 1 to 4 As shown, this embodiment discloses a traditional Chinese medicine decoction piece dispensing mechanism, including a support 1. The support 1 is equipped with multiple maintenance slide rails 5. In this embodiment, there are four maintenance slide rails 5, and each maintenance slide rail 5 has a dispensing unit 2 sliding on it, meaning there are also four dispensing units 2. Each dispensing unit 2 includes a single-cabinet support 6 and a dispensing cabinet 601. The single-cabinet support 6 has a material discharge channel 3 in the middle, and multiple dispensing cabinets 601 are installed on both sides of the single-cabinet support 6. In this embodiment, the total number of dispensing cabinets 601 is eight, meaning four dispensing cabinets 601 are installed on each side of the single-cabinet support 6. All dispensing cabinets 601 are connected to the material discharge channel 3. The dispensing mechanism consists of a dispensing module composed of 32 dispensing cabinets 601. Eight dispensing cabinets 601 are arranged and installed on a material discharge channel 3 to form a single dispensing unit. Four dispensing units 2 are arranged and installed on a support 1 via maintenance slide rails 5 to form a dispensing module. The four dispensing units 2 on each dispensing module can slide freely relative to the dispensing module, which facilitates routine maintenance and replacement of parts. Each dispensing unit 2 is equipped with a material discharge channel 3, which has 8 medicine dispensing ports. Each medicine dispensing port corresponds to a dispensing cabinet 601. The dispensing cabinet 601 is installed on each medicine dispensing port on the material discharge channel 3 via a cabinet bracket 6. The cabinet bracket 6 has a ramp slide structure so that the medicine discharged from the weighing hopper 204 on the dispensing cabinet 601 after each weighing can smoothly fall into the medicine dispensing port through the inside of the material discharge channel 3. Since the dispensing module has a gate-shaped structure below, a conveyor line or AGV trolley can be used to transport medicine frames or turnover boxes to catch the medicine discharged from each medicine dispensing port in sequence.

[0060] Each dispensing unit 2 is equipped with a material discharge channel 3, which has 8 medicine dispensing ports. Each medicine dispensing port corresponds to a dispensing cabinet 601. The dispensing cabinet 601 is installed on each medicine dispensing port on the material discharge channel 3 via a cabinet bracket 6. The cabinet bracket 6 has a ramp slide structure so that the medicine discharged from the weighing hopper 204 on the dispensing cabinet 601 after each weighing can smoothly fall into the medicine dispensing port through the inside of the material discharge channel 3. Since the dispensing module has a gate-shaped structure below, a conveyor line or AGV trolley can be used to transport medicine frames or turnover boxes to catch the medicine discharged from each medicine dispensing port in sequence.

[0061] The dispensing module is equipped with 4 rows of dispensing units 2; each dispensing unit 2 has 1 dispensing port, 8 dispensing cabinets 601 and a set of maintenance slide rails 5.

[0062] Both sides of the single cabinet support 6 are equipped with a dosing port that is connected to the material discharge channel 3. The dosing port is equipped with a ramp channel that is connected to the dispensing cabinet 601.

[0063] like Figure 4 As shown, in this embodiment, the maintenance slide rail 5 includes a slide rail bracket 501, a guide rail 502, and pulleys 503. The slide rail bracket 501 is mounted on the bracket 1, and a plurality of pulleys 503 are mounted on the slide rail bracket 501. The guide rail 502 is mounted on the adjustment unit 2, and the guide rail 502 slides on the slide rail bracket 501 via the pulleys 503. Each dispensing unit 2 is mounted on a support 1 via a maintenance slide rail 5. The support 1 has four sets of slide rail brackets 501, and each set of slide rail brackets 501 has 22 pulleys 503. The pulleys 503 are stainless steel bearing wheels. Each dispensing unit 2 slides freely on the support 1 via a guide rail 502 mounted at its lower end, which facilitates routine maintenance and parts replacement. Furthermore, when one dispensing unit 2 on one support 1 is pulled out for maintenance, since each dispensing unit 2 has an independent power supply and communication mechanism, the multiple dispensing cabinets 601 on the other three dispensing units 2 can still work normally, ensuring the overall dispensing efficiency and stability of the dispensing mechanism.

[0064] The bottom of the material discharge channel 3 is provided with a discharge port, which is a straight outlet and / or a funnel outlet.

[0065] The dispensing cabinet 601 includes a hopper 201, a discharge hopper 202, and a weighing hopper 204. The discharge hopper 202 is connected to the hopper 201 and conveys the medicinal materials to the weighing hopper 204. The weighing hopper 204 is connected to the discharge hopper 202 and conveys the weighed medicinal materials into the discharge channel 3. The silo 201 is responsible for storing the Chinese medicinal materials to be dispensed. The discharge hopper 202 is installed below it. The Chinese medicinal materials in the silo 201 enter the discharge hopper 202 through the medicine drop outlet below the silo 201. The discharge hopper 202 can continuously and evenly transport the Chinese medicinal materials to the weighing hopper 204 through vibration. The weighing hopper 204 has a weighing function and a gate opening and closing function. After the weighing hopper 204 completes the weighing, it opens the gate and discharges the Chinese medicinal materials onto the single cabinet support 6 by its own weight. The Chinese medicinal materials enter their respective discharge channels 3 through the sliding structure of the single cabinet support 6 and finally fall out from the medicine drop outlet, completing the dispensing of one Chinese medicinal material in the prescription.

[0066] This embodiment also discloses a dispensing system with the aforementioned Chinese herbal medicine dispensing mechanism, including an upper-level central processing unit. Each dispensing cabinet 601 is equipped with a lower-level control unit connected to the upper-level central processing unit. The lower-level control units control the dispensing of medicine from the dispensing cabinet 601. Each dispensing cabinet 601 is managed by an individual lower-level control unit, and multiple lower-level control units are all managed by the upper-level central processing unit. When the dispensing machine is working, the upper-level central processing unit sends the dispensing task of multiple Chinese herbal medicines within a single prescription to the corresponding multiple lower-level control units based on the pre-stored Chinese herbal medicines. Each lower-level control unit receiving a dispensing task controls the discharge hopper 202 in its corresponding dispensing cabinet 601 to continuously dispense medicine. The Chinese medicinal materials conveyed by the discharge hopper 202 are discharged into the weighing hopper 204. The lower-level control unit continuously reads the weight data of the Chinese medicinal materials inside the weighing hopper 204. When the weight requirement of the dispensing task is met, the lower-level control unit controls the discharge hopper 202 to stop working. At this time, the weighing hopper 204 will not open its gate to discharge medicine. When the conveyor line or AGV trolley transports the medicine frame or turnover box to the bottom of its corresponding medicine drop port, the upper-level central processing unit issues a medicine discharge command to the lower-level control unit. The lower-level control unit receiving the command then controls the weighing hopper 204 in its corresponding dispensing cabinet 601 to open its gate, completing the dispensing task. Since one dispensing unit 2 is equipped with eight dispensing cabinets 601, multiple dispensing tasks can be completed simultaneously, ensuring the overall dispensing efficiency of the dispensing mechanism.
