Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine decoction technology, and in particular to an automatic decoction method. Background Technology

[0002] Currently, automated decoction technology for traditional Chinese medicine (TCM) is gradually emerging, which can improve decoction efficiency and is very important for many patients. Because TCM requires proportioning (the weight of the herbs and water) and heating, the medicine container needs to be moved and poured. Currently, existing technologies can only handle the conveying and clamping of the container. The applicant previously applied for an automated decoction room feeding device and method (application number 202211686372.5). The decoction process involves first placing the medicine bag and water into the medicine container (operation outside the decoction room itself), then conveying the container closer to the decoction room, and finally transferring it to the top of the decoction machine using a clamp. The water and medicine bag are then poured into the decoction machine. After decoction, the resulting liquid is directly sent to an automatic packaging machine for packaging into smaller packages. The medicine bags inside the decoction machine are then manually removed. The medicine barrel is then returned to the conveyor roller by the clamp, and then the medicine barrel is cleaned manually.

[0003] However, the above-mentioned steps for decocting medicine are unreasonable, with at least the following drawbacks: 1. The medicine bag needs to be removed manually, and the bag is very hot after decoction, which can easily cause burns; 2. When the medicine bag needs to be replaced, the inner cavity of the decoction machine needs to be cleaned. The cleaning process is lengthy and the decoction process cannot be carried out, so the decoction efficiency is relatively low. In particular, because the decoction water churns inside during the decoction process, the inner wall of the decoction machine near the top will also have decoction residue, so more water needs to be added for cleaning, resulting in increased water consumption; 3. The medicine barrels also need to be cleaned after use, and after cleaning, they need to be manually transported one by one to the upstream of the conveyor roller line, so the operators need to move the medicine barrels, which is labor-intensive; 4. The medicine barrels need to be tilted, which can easily cause water to splash. The splashed water reduces the amount of decoction water and affects the final amount of decoction. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic decoction method. This automatic decoction method eliminates the need for manual removal of the medicine bag and the step of emptying the medicine bag from the medicine bag in the medicine bag. This not only improves safety performance, but also avoids the situation where the amount of water is reduced due to splashing during emptying, and improves the accuracy of the final decoction amount.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic decoction method, comprising the following steps:

[0006] S1. An automatic decoction room is provided, comprising a decoction room body, a medicine inlet channel on the decoction room body, a medicine barrel input assembly located within the medicine inlet channel, one end of the medicine barrel input assembly extending into the decoction room body, and the other end extending to the outside of the decoction room body; the decoction room body is provided with multiple decoction machines, a buffer platform, and an automatic decoction packaging machine, each decoction machine including a decoction machine body, the upper end of the decoction machine body being open and provided with a placement chamber for placing medicine barrels, and an electric heating device for heating the medicine barrels in the placement chamber being provided within the decoction machine body. The decoction room body is equipped with a lifting device for lifting medicine barrels from the buffer platform to the placement chamber. The decoction room body is also equipped with a top cover for sealing the top of the decoction machine. The top cover is driven by a top cover transfer device. The top cover is equipped with a water inlet pipe and a medicine extraction pipe. The medicine extraction pipe extends to the bottom of the medicine barrel. The water inlet pipe is connected to the water addition system. The medicine extraction pipe is connected to the liquid inlet of the automatic decoction packaging machine. The decoction room body is also equipped with a cleaning water tank. The decoction room body is also equipped with a lifting device for moving medicine barrels from the decoction machine to the cleaning water tank.

[0007] S2. The medicine barrels containing medicine bags are fed one by one from the medicine barrel input assembly into the decoction room body;

[0008] S3. Place the medicine barrels into the lifting device and lift and arrange them on the buffer platform;

[0009] S4. The top cover is moved from the top cover transfer device to the avoidance state, and the medicine barrel is placed into the lifting device to lift the medicine barrel on the buffer platform and put it into the placement chamber of the decoction machine body.

[0010] S5. The top cover is moved by the top cover transfer device and seals the top opening of the decoction machine. When sealing the cover, the medicine suction pipe and the water inlet pipe are inserted into the medicine barrel.

[0011] S6. The water supply system injects a measured amount of clean water into the medicine tank through the water inlet pipe and then stops injecting;

[0012] S7. The electric heating device of the decoction machine is activated to heat the medicine pot for decoction.

[0013] S8. After the decoction is completed, the decoction in the medicine barrel is sent to the automatic decoction packaging machine through the medicine extraction tube to be packaged into small bags of decoction.

[0014] S9. After the drug extraction is completed, the top cover is opened by the top cover transfer device and moved to the avoidance position;

[0015] S10. The medicine barrel is removed from the decoction machine by the lifting device and sent to the cleaning water tank for cold water rinsing.

[0016] As a preferred embodiment, the automatic decoction method further includes a cleaning step for rinsing the residual decoction from the previous decoction. The cleaning step is performed after step S6 and specifically includes the following steps:

[0017] S61. After injection, the medicine extraction tube is started, drawing the newly added clean water in the medicine tank into the automatic decoction packaging machine, and cleaning the internal pipes of the automatic decoction packaging machine at the same time.

[0018] S62. During the cleaning process, clean water is continuously injected into the inlet pipe until the cleaning time ends. Therefore, when the herb bag formula is changed, after the new herb container is placed into the decoction machine, clean water can be injected and the container can be pulled out through the herb extraction pipe. This allows for the cleaning of the pipes between the automatic decoction packaging machine and the decoction machine before proceeding with the decoction process. Since the herb container is already clean, only the residual herbs inside the pipes and the pipes within the automatic decoction packaging machine need to be cleaned; the container itself does not need to be cleaned. This reduces the amount of water injected into the container, decreases cleaning time, and improves efficiency.

[0019] As a preferred embodiment, the lifting device for removing the medicine barrel and the lifting device for placing the medicine barrel are the same device. In step S10, before moving the medicine barrel to the cleaning water tank, it is first moved above the medicine bag collection pool, and the medicine bags in the medicine barrel are emptied before it is moved to the cleaning water tank. In this way, after the medicine barrel is removed, the medicine bags can be emptied into the medicine bag collection pool first, and then the medicine barrel is sent into the cleaning water tank for cleaning.

[0020] As a preferred embodiment, the medicine barrel is further provided with a vertically arranged dividing net. The dividing net divides the medicine barrel into a medicine bag cavity for placing medicine bags and a filtrate cavity. The medicine bags are placed into the medicine bag cavity, and the medicine barrel is adjusted to a specified angle when it is transported on the medicine barrel input assembly. When the medicine barrel is placed into the decoction machine body by the lifting device, the medicine suction tube corresponds to the bottom of the filtrate cavity. In this way, the dividing net provided in the medicine barrel can separate the medicine bags, and the medicine suction tube can be accurately inserted to the bottom, avoiding collision with the medicine bags and thus preventing it from being inserted to the bottom.

[0021] As a preferred embodiment, the method further includes a medicine barrel recycling step S11, in which the cleaned medicine barrel is placed on a medicine barrel recycling device and transported to the medicine barrel input assembly.

[0022] As a preferred embodiment, the bottom of the inner cavity of the medicine barrel is inclined, and when the medicine extraction tube is inserted into the filtrate chamber, the lower end corresponds to the lowest point of the bottom of the medicine barrel, so that all the decoction can be extracted.

[0023] After adopting the above technical solution, the effects of this invention are as follows: 1. This automatic decoction method directly lifts the medicine barrel and places it into the decoction machine body. The top cover lowers to seal the top opening of the decoction machine body, and water is then added for decoction. This eliminates the need to pour out the medicine bag and water in the medicine barrel, avoiding water splashing and loss of clean water, ensuring that the final decoction volume meets the requirements. 2. After the automatic decoction room completes the decoction, the decocted medicine is sent to the automatic decoction packaging machine for packaging through the medicine extraction tube. After the decoction is completed, the entire medicine barrel can be taken out and placed in the cleaning water tank for cleaning. Cold water can be used for cleaning to cool down the medicine bag and medicine barrel, thus preventing the cleaning personnel from being scalded. It also eliminates the need to remove the hot medicine bag, avoiding burns. During the cleaning process, the next medicine barrel can be placed into the decoction machine body for decoction.

[0033] The present invention will be further described in detail below through specific embodiments.

[0034] An automated method for decocting medicine includes the following steps:

[0035] S1. An automatic decoction room is provided, comprising a decoction room body 1. The decoction room body 1 has a medicine inlet channel, and a medicine barrel input assembly 2 is located within the medicine inlet channel. One end of the medicine barrel input assembly 2 extends into the decoction room body 1, and the other end extends to the outside of the decoction room body 1. The decoction room body 1 contains multiple decoction machines, a buffer platform 6, and an automatic decoction packaging machine 9. Each decoction machine includes a decoction machine body 8, the upper end of which is open and has a placement chamber for placing medicine barrels 7. An electric heating device is provided inside the decoction machine body 8 to heat the medicine barrels 7 in the placement chamber. The decoction room body 1... The decoction room body 1 is equipped with a lifting device 3 for lifting medicine barrels 7 from the buffer platform 6 to the placement chamber. The body 1 is also equipped with a top cover 11 for sealing the top of the decoction machine. The top cover 11 is driven by a top cover transfer device 4. The top cover 11 is equipped with a water inlet pipe 12 and a medicine extraction pipe 13. The medicine extraction pipe 13 extends into the bottom of the medicine barrel 7. The water inlet pipe 12 is connected to the water supply system. The medicine extraction pipe 13 is connected to the liquid inlet of the automatic decoction packaging machine 9. The decoction room body 1 is also equipped with a cleaning water tank 10. The decoction room body 1 is also equipped with a lifting device for moving the medicine barrel 7 from the decoction machine to the cleaning water tank 10.

[0036] In this embodiment, the medicine barrel 7 is further provided with a vertically arranged dividing net 74. The dividing net 74 divides the medicine barrel 7 into a medicine bag cavity 72 for placing medicine bags and a filtrate cavity 73. The medicine bags are placed into the medicine bag cavity 72, and the medicine barrel 7 is adjusted to a specified angle when it is conveyed on the medicine barrel input assembly 2. When the medicine barrel 7 is placed into the decoction machine body 8 by the lifting device 3, the medicine extraction tube 13 corresponds to the bottom of the filtrate cavity 73. The bottom of the inner cavity of the medicine barrel 7 is set in an inclined shape. When the medicine extraction tube 13 extends into the filtrate cavity 73, its lower end corresponds to the lowest point of the bottom of the medicine barrel 7. The dividing net provided in the medicine barrel 7 can separate the medicine bags, so the medicine extraction tube 13 can be accurately inserted to the bottom, avoiding collision with the medicine bags and being unable to be inserted to the bottom. In this way, all the decoction can be extracted. And since the filtrate cavity 73 that can be separated by the dividing net is larger than the size of the medicine extraction tube 13, the position of the medicine barrel 7 on the medicine barrel 7 conveying assembly does not need to be very precise.

[0037] S2. The medicine barrels 7 containing medicine bags are fed one by one from the medicine barrel input assembly 2 into the decoction room body 1;

[0038] S3. Place the medicine barrel 7 into the lifting device 3 and lift and arrange the medicine barrel 7 onto the buffer platform 6;

[0039] S4. The top cover 11 is moved from the top cover transfer device 4 to the avoidance state, and the medicine barrel is placed into the lifting device 3 to lift the medicine barrel 7 on the buffer platform 6 and put it into the placement chamber of the decoction machine body 8.

[0040] S5. The upper cover 11 is moved by the upper cover transfer device 4 and seals the upper opening of the decoction machine body 8. When sealing the cover, the medicine extraction pipe 13 and the water inlet pipe 12 extend into the medicine barrel 7.

[0041] S6. The water supply system injects a measured amount of clean water into the medicine tank 7 through the water inlet pipe 12 and then stops injecting;

[0042] The automatic decoction method also includes a cleaning step to wash away the residual decoction from the previous decoction. This cleaning step is performed after step S6 and specifically includes the following steps:

[0043] S61. After the injection is completed, the medicine extraction tube 13 is started, and the newly added clean water in the medicine tank 7 is pumped into the decoction automatic packaging machine 9, which also cleans the internal pipes of the decoction automatic packaging machine 9 at the same time.

[0044] S62. During the cleaning process, the water inlet pipe 12 continuously injects clean water through the extraction pipe 13 until the cleaning time ends. When the medicine bag formula is changed, a new medicine bag is placed in the new medicine barrel 7. After the entire medicine barrel 7 is placed into the decoction machine body 8, clean water can be injected and extracted through the extraction pipe 13. This allows for the cleaning of the pipes between the automatic decoction packaging machine 9 and the decoction machine before the decoction process can begin. Since the medicine barrel 7 is already clean, only the residual medicine inside the pipes and the pipes inside the automatic decoction packaging machine 9 need to be cleaned. There is no need to clean the barrel wall of the medicine barrel 7. This reduces the amount of water injected into the medicine barrel 7, decreases the cleaning water consumption, reduces the cleaning time, and improves efficiency.

[0045] S7. The electric heating device of the decoction machine body 8 is activated to heat the medicine barrel 7 for decoction;

[0046] S8. After the decoction is completed, the decoction in the medicine barrel 7 is sent to the automatic decoction packaging machine 9 through the medicine extraction tube 13 for packaging into small bags of decoction.

[0047] S9. After the drug extraction is completed, the top cover 11 is opened by the top cover transfer device 4 and moved to the avoidance state;

[0048] S10. The medicine barrel removal and lifting device removes the medicine barrel 7 from the decoction machine body 8 and sends it to the cleaning water tank 10 for cold water rinsing. The method also includes a medicine barrel 7 recycling step S11, in which the cleaned medicine barrel 7 is placed on the medicine barrel 7 recycling device and transported to the medicine barrel input assembly 2.

[0049] The lifting device for removing the medicine barrel and the lifting device for placing the medicine barrel into the lifting device 3 are the same device. In step S10, before the medicine barrel 7 is moved to the cleaning water tank 10, it is first moved above the medicine bag collection pool. The medicine bags in the medicine barrel 7 are then emptied before it is moved to the cleaning water tank 10. In this way, after the medicine barrel 7 is removed, the medicine bags can be emptied into the medicine bag collection pool first, and then the medicine barrel 7 is sent into the cleaning water tank 10 for cleaning.

[0050] In addition, this invention also discloses an automatic decoction room, such as... Figures 1 to 7 As shown, the system includes a decoction room body 1, which has a medicine inlet channel. A medicine barrel input assembly 2 is located within the medicine inlet channel. In this embodiment, the medicine barrel input assembly 2 uses a conveyor roller conveyor, and its specific structure is the same as that described in patent application number 202211686372.5. The medicine barrel 7 is fed with a corresponding medicine bag before being input into the decoction room body 1 by the medicine barrel input assembly 2.

[0051] One end of the medicine barrel input assembly 2 extends into the decoction room body 1, and the other end extends to the outside of the decoction room body 1. The decoction room body 1 is equipped with multiple decoction machines, a buffer platform 6, and an automatic decoction packaging machine 9. The buffer platform 6 is used to temporarily place the medicine barrels 7. The automatic decoction packaging machine 9 is a commonly used packaging machine; its structure and principle are currently known and can be purchased commercially.

[0052] Each decoction machine includes a decoction body 8, with an opening at the top and a placement chamber for holding a medicine barrel 7. The decoction body 8 is equipped with an electric heating device for heating the medicine barrel 7 in the placement chamber. This electric heating device can be a conventional electric heating plate or electromagnetic induction heating. Alternatively, an electric heating plate can be directly placed at the bottom of the placement chamber to heat the medicine barrel 7. Electromagnetic induction heating can also be used, where an electromagnetic coil generates a magnetic field to directly heat the medicine barrel 7. This heating method ensures that the medicine barrel 7 is heated evenly throughout, eliminating the need to conduct heat through the bottom, resulting in higher thermal efficiency.

[0053] The decoction room body 1 is equipped with a lifting device 3 for lifting the medicine barrel 7 from the buffer platform 6 to the placement chamber. The decoction room body 1 is also equipped with an upper cover 11 that seals the upper opening of the decoction machine. The upper cover 11 is driven by an upper cover transfer device 4. The upper cover 11 is equipped with a water inlet pipe 12 and a medicine extraction pipe 13. The medicine extraction pipe 13 extends into the bottom of the medicine barrel 7. The water inlet pipe 12 is connected to a water supply system. The water supply system can be equipped with a flow meter to control the water supply.

[0054] The medicine extraction tube 13 is connected to the liquid inlet of the automatic decoction packaging machine 9. The decoction room body 1 is also equipped with a cleaning water tank 10. The decoction room body 1 is also equipped with a lifting device for moving the medicine barrel 7 in the decoction machine to the cleaning water tank 10.

[0055] like Figure 3 and Figure 4As shown, the medicine barrel 7 is placed into the lifting device 3, which includes a conveyor frame 31 fixed inside the decoction room body 1. A longitudinal beam 32 extending from the buffer platform 6 to the decoction machine is provided on the conveyor frame 31. A transverse beam 33 is longitudinally slidably mounted on the longitudinal beam 32, and a transverse slide block 34 is transversely slidably mounted on the transverse slide block 33. A vertical beam 35 is fixedly mounted on the transverse slide block 34, and a lifting seat 36 is longitudinally slidably mounted on the vertical beam 35. A medicine barrel 7 clamp 37 for holding the medicine barrel 7 is fixedly mounted on the lifting seat 36. A flange 71 is provided at the upper opening of the medicine barrel 7. The longitudinal beam 32 is driven by a longitudinal power device, the transverse beam 33 is driven by a transverse power device, and the lifting seat 36 is driven by a medicine barrel 7 lifting power device. Preferably, the longitudinal power device, the transverse power device, and the medicine barrel 7 lifting power device are all electric slides to accurately control the movement precision.

[0056] like Figure 6 As shown, the medicine barrel 7 clamp 37 includes two clamping arms 371, which are driven by a clamping power device 372. The clamping power device 372 is driven by a cylinder, which drives the two clamping arms 371 to move closer together or separate. An arc-shaped clamping block 373 is rotatably mounted on each of the two clamping arms 371. One of the arc-shaped clamping blocks 373 is driven by a rotary power element 375, which can be either a rotary cylinder or a rotary motor. Each arc-shaped clamping block 373 is provided with a clamping groove 374 for clamping the flange edge 71.

[0057] like Figure 3 and Figure 4 As shown, the upper cover transfer device 4 includes a transfer frame 41, on which a transfer slide 42 is slidably mounted. A lifting cylinder 43 is fixedly mounted on the transfer slide 42, and the upper cover 11 is fixedly mounted at the lower end of the lifting cylinder 43. The transfer slide 42 is driven by a transfer power device to slide between the avoidance station and the working station. The upper cover 11 can seal the upper opening of the decoction machine body 8. In this embodiment, after the medicine barrel 7 is placed in the placement cavity, the flange edge 71 at the upper end of the medicine barrel 7 is higher than the upper opening of the decoction machine body 8, so as to facilitate the clamping of the medicine barrel 7 by the clamp 37. The upper cover 11 can cover the medicine barrel 7 and seal its lower edge with the decoction machine body 8. At the same time, the upper cover 11 is also squeezed and sealed with the upper opening of the medicine barrel 7. Of course, the lifting cylinder 43 can also use other power, such as a motor and a screw nut mechanism to drive the upper cover 11 to lift.

[0058] In this embodiment, the medicine barrel removal lifting device and the medicine barrel 7 placement lifting device 3 are the same set of devices, and the medicine barrel 7 clamp 37 of the medicine barrel 7 placement lifting device 3 covers the cleaning water tank 10. In this way, the medicine barrel 7 can be placed and removed by using the medicine barrel 7 placement lifting device 3, and after removal, the medicine bag inside the medicine barrel 7 can be discarded by tilting the medicine barrel 7, further saving the operator's labor intensity.

[0059] The automatic decoction room includes a medicine barrel recycling and conveying device 5, and the medicine barrel 7 recycling device is located outside the decoction room body 1. The medicine barrel recycling and conveying device 5 connects the cleaning water tank 10 to the medicine barrel input assembly 2, so that the cleaned medicine barrel 7 can be directly recycled. At this time, it is only necessary to put the medicine bag into the medicine barrel 7 at the medicine barrel input assembly 2, without the need for water filling, making the operation simpler.

[0060] The bottom of the medicine container 7 is inclined, and the lower end of the medicine extraction tube 13 corresponds to the lowest point of the bottom of the medicine container 7, which allows for better and more complete extraction of the medicine. The medicine container 7 is also equipped with a vertically arranged partition net 74, which divides the medicine container 7 into a medicine bag cavity 72 for placing medicine bags and a filtrate cavity 73. The medicine extraction tube 13 extends into the bottom of the filtrate cavity 73, so that when the top cover 11 descends, the medicine extraction tube 13 can be inserted into the filtrate cavity 73, avoiding collision between the medicine extraction tube 13 and the medicine bag, which would cause the top cover 11 to descend unsmoothly.

[0061] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and alterations made to the technical solutions of the present invention without departing from the spirit of the present invention shall fall within the protection scope defined by the claims of the present invention.
