Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine decoction, in particular to automatic rapid decoction equipment for Chinese medicine decoction pieces. Background Art

[0002] Chinese herbal medicine pieces are made by processing Chinese herbal medicine into coarse granules or powders of 0.2 to 10 mm in size according to regulations, decocted in water, and the residue is removed to extract the juice or taken together with the residue. The decoction of Chinese herbal medicine pieces is increasingly being decocted by a decoction center, and then the packaged decoction is delivered to the patient.

[0003] Currently, most of the decoction equipment on the market is in the form of single-pot and single-stove independent decoction. It can also automatically control the decoction process, but each pot and each stove has independent operation and decoction program setting, and needs to be completed manually. In addition, the temperature of the boiler is high during the decoction process. Manual decoction operation has safety risks such as easy scalding and boiler tipping over, and is inefficient, which cannot meet the current growing decoction demand of decoction centers. Summary of the invention

[0004] In view of the low efficiency of the above-mentioned decoction equipment, the present invention provides an automatic and rapid decoction equipment for decocting loose Chinese medicine slices, which integrates multiple decoction points into a decoction table and connects the medicine pot from the preceding workstation through several branch conveyor lines, thereby reducing manual intervention in the decoction process, improving work efficiency, and realizing automatic and rapid decoction.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an automatic rapid decoction device for decoction pieces of Chinese medicine, comprising at least one decoction station, the decoction station comprising a branch conveyor line and a decoction table, one end of the branch conveyor line is connected to a water adding station, and the other end is connected to a medicine pouring station, the decoction table comprises a plurality of decoction points, the decoction points comprise two soaking positions and one medicine decoction position, the soaking position is provided with a soaking conveyor belt docking with the branch conveyor line so that the medicine pot of the branch conveyor line enters the soaking position through the soaking conveyor belt under set control;

[0006] The decoction table further comprises a lifting frame for lifting the medicine pot on the soaking position and placing it in the decoction position and / or lifting the medicine pot in the decoction position and placing it on the branch conveyor line;

[0007] The decoction position includes a steam heater arranged inside the decoction table, a steam heating port for placing the medicine pot opened on the decoction table corresponding to the position of the steam heater, and a decoction cover corresponding to the steam heating port.

[0008] As a further improvement of the invention: the soaking position is located at the end of the soaking conveyor belt and a positioning frame is provided, so that the medicine pot is positioned at a designated position by the positioning frame during the continuous transmission of the soaking conveyor belt, and a lifting and pouring device is provided at the designated position, so that the medicine pot on the soaking position is lifted by the lifting and pouring device and poured into the medicine pot on the decoction position.

[0009] As a further improvement of the invention: a vertical rod extending upward is provided on one side of the frying table corresponding to each soaking position, the end of the vertical rod extends toward the positioning frame and is provided with a telescopic cylinder, the output end of the telescopic cylinder is provided with a pressing net, the center of the pressing net is aligned with the positioning center of the positioning frame.

[0010] As a further improvement of the invention: the water adding station includes a positioning sensor for sensing the medicine pot in place, a water adding scanner for scanning the marking on the medicine pot barrel, and a water adding pipeline for filling water into the medicine pot. The medicine pot is positioned after being sensed by the positioning sensor on the conveyor line, and the marking on the medicine pot barrel is identified by the water adding scanner to obtain the prescription information associated with the current medicine pot and the information of medicinal materials placed through the dispensing station and the corresponding water injection amount information. The water adding pipeline is controlled by the water adding control module to add water to the medicine pot in a quantitative manner according to the water injection amount information.

[0011] As a further improvement of the invention: the conveyor line and branch conveyor line are provided with a plurality of independently controlled conveyor plates, each conveyor plate has a unique coding and an independently controlled transmission power mechanism, the conveyor plates run on the track of the conveyor line extended by the transmission power mechanism and have belts for conveying toward both sides of the track.

[0012] As a further improvement of the invention: the conveyor line is provided with a decoction scanner between the water adding station and the decoction station. After the decoction scanner identifies the label on the barrel of the medicine pot passing by, it obtains the idle decoction point on the current decoction station, determines the position of the decoction table according to the idle decoction point, and controls the medicine pot to enter the branch conveyor line of the decoction table. A decoction sub-scanner is provided at the front end of the branch conveyor, which is used to scan the label on the barrel of the medicine pot passing by and then form feedback to the conveyor line, and is used to determine the number of medicine pots required for the current prescription according to the acquired prescription information and judge whether the soaking position is idle, thereby controlling the current medicine pot to enter the soaking position.

[0013] As a further improvement of the invention: after the decoction sub-scanner scans the passed medicine pot barrel body mark, the prescription information associated with the current medicine pot is obtained and the number of medicine pots required for the current prescription is determined. When the number of medicine pots required for the prescription is less than or equal to two, the branch conveyor line directly conveys the medicine pot to the soaking position. When the number of medicine pots required for the prescription is greater than two, it is determined that the current medicine pot belongs to the front decoction process or the back decoction process in the front decoction and back decoction process. The front decoction and back decoction process pre-sets the decoction order in the adjustment process and forms an association through the medicine pot barrel body mark;

[0014] If it is a pre-decoction process, determine whether the soaking position is free: if it is free, directly enter the free soaking position through the soaking conveyor belt; if it is not free, control the hanging lifting frame to put the medicine pot of the pre-decoction process of one of the soaking positions into the steam heating port to make the soaking position free;

[0015] If it is the next process, it will enter the standby area for frying.

[0016] As a further improvement of the invention: when the current medicine pot belongs to the latter process in the process of pre-decoction and post-decoction, the number of medicine pots in the pre-decoction process in the current prescription is determined:

[0017] If there are three or more medicine pots in the front-end decoction process, the current medicine pot will directly enter the standby area for decoction, and a manual intervention warning will be issued when the front-end decoction process starts;

[0018] If there are two medicine pots in the front decoction process, it is obtained whether there are medicine pots for the next process at the two immersion positions. If there are medicine pots for the next process, the current medicine pot directly enters the standby area for decoction, and a manual intervention warning is issued when the front decoction process starts. If there are no medicine pots for the next process, the branch conveyor line directly transfers the current medicine pot to the immersion position;

[0019] If the number of medicine pots in the front-decoction process is one, it is determined whether both immersion positions are idle. If both immersion positions are idle, the branch conveyor line directly transfers the current medicine pot to the immersion position.

[0020] As a further improvement of the invention: if there is only one medicine pot in the pre-decocting process, when there is only one or no soaking position vacant, it is determined whether the medicine pot in the pre-decocting process has entered the decoction position:

[0021] If only one soaking position is free, and the medicine pot of the previous decoction process has entered the decoction position, the branch conveyor line will directly transfer the current medicine pot to the free soaking position. Otherwise, it will wait for the medicine pot of the previous decoction process to enter the decoction position before executing the next step;

[0022] If there is no vacant soaking position, when the medicine pot of the previous decoction process is in the soaking position, the hanging lifting frame is controlled to put the medicine pot of the previous decoction process into the decoction position to make the soaking position vacant; when the medicine pot of the previous decoction process is in the decoction position, the current medicine pot directly enters the standby area for decoction, and a manual intervention alarm is issued when the previous decoction process starts.

[0023] As a further improvement of the invention: it includes a decoction control method, wherein the decoction control method uses an automatic rapid decoction device to perform the following steps:

[0024] The sensing signal of the positioning sensor passing through the water adding station is obtained. The sensing signal corresponds to the conveying plate to control the medicine pot to be positioned at the designated water adding position. The medicine pot barrel body mark is identified by the water adding scanner at the designated position to obtain the water injection amount information and control the quantitative water injection of the water adding pipeline;

[0025] The medicine pot coming out of the water adding station passes through the decoction scanner and obtains the water adding and decoction process information from the barrel body mark. Combined with the idle decoction points on the current decoction station, the decoction table position is determined according to the idle decoction points, and the medicine pot is controlled to enter the branch conveyor line of the decoction table. The decoction sub-scanner before the branch conveyor scans the medicine pot barrel body mark and then forms feedback to the conveyor line;

[0026] The branch conveyor line transfers the medicine pot to the soaking side, and under the set control, it enters the soaking position through the soaking conveyor belt, and then the medicine pot on the soaking position is lifted by the lifting frame and placed in the decoction position;

[0027] The soaking time of the prescription information is obtained. During the soaking process, since the medicine pot at the soaking position is accurately positioned, the pressing net is controlled by the telescopic cylinder to press down toward the medicine pot, so that the boiled and loose medicinal pieces are completely immersed in water;

[0028] When the medicine pots of all the pre-decoction processes meet the corresponding set soaking time, the decoction cover is closed and the steam heater is started to decoct at the set temperature, pressure and decoction parameters; after the decoction is completed according to the set decoction process, the medicine pots in the decoction position are lifted by the hanging lifting frame and placed on the branch conveyor line, and the medicine pots enter the medicine pouring position from the conveyor line.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention integrates multiple decoction points into a decoction table and effectively distributes them through a number of branch conveyor lines, thereby improving the efficiency of decocting medicines, reducing manual intervention in the process from soaking the pieces in water to decocting, and greatly reducing the tediousness and errors of manual operation. It not only improves the efficiency and quality of decocting Chinese medicine pieces, but also effectively reduces the labor costs of hospitals or pharmacies. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0038] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0039] The embodiment of the present invention discloses an automatic rapid decoction device for decoction pieces of traditional Chinese medicine, Figure 1 and Figure 2 , including at least one decoction station 100, the decoction station 100 includes a branch conveyor line 200 and a decoction table 300, one end of the branch conveyor line 200 is connected to a water adding station 400, and the other end is connected to a medicine pouring station 500, the decoction table 300 includes a plurality of decoction points 310, the decoction points 310 include two soaking positions 311 and a decoction position 312, the soaking position 311 is provided with a soaking conveyor belt 313 docking the branch conveyor line 200 so that the medicine pot of the branch conveyor line 200 enters the soaking position 311 through the soaking conveyor belt 313 under set control;

[0040] The decoction table 300 also includes a lifting frame 320, which is used to lift the medicine pot on the soaking position 311 and place it in the decoction position 312 and / or lift the medicine pot in the decoction position 312 and place it on the branch conveyor line 200; it should be noted that the lifting frame adopts the existing technology to lift or lower and move the decoction position.

[0041] The decoction position 312 includes a steam heater arranged inside the decoction table, a steam heating port 314 for placing the medicine pot on the decoction table corresponding to the position of the steam heater, and a decoction cover 315 corresponding to the steam heating port.

[0042] In this embodiment, the conveyor line and the branch conveyor line are provided with a number of independently controlled conveyor plates 210, each conveyor plate having a unique coding and independently controlled transmission power mechanism, and the conveyor plate 210 runs on the track of the conveyor line extended by the transmission power mechanism and has a belt for conveying toward both sides of the track. In other words, the conveyor plate has a power device to drive itself to walk on the track on the conveyor line and / or the branch conveyor line, and at a specified position, the medicine pot on the belt can also be conveyed outwards through the belt toward both sides of the track. It should be noted that this embodiment does not impose any form of restrictions on the transmission power mechanism of the conveyor plate and the means and principles for realizing its own walking and transmission toward both sides of the belt. The technicians can set it according to the actual use requirements, which can be driven by a motor to drive the roller to walk on the track, etc. The conveyor plate can be operated on the conveyor line by using the existing technology.

[0043] In this embodiment, the immersion position 311 is located at the end of the immersion conveyor belt 313 and is provided with a positioning frame 316, so that the medicine pot is positioned at a specified position by the positioning frame 316 during the continuous transmission of the immersion conveyor belt 316, and the positioning frame is an arc-shaped bar or baffle, and the arc-shaped contour is similar to the outer wall contour of the medicine pot, so that the medicine pot continuously provides a force toward the positioning frame on the immersion conveyor belt, and the positioning coordination of the arc-shaped contour and the outer wall contour is used to achieve precise positioning of the medicine pot, providing an accurate position for the subsequent lifting and pouring process and sufficient immersion of the pressing net when sinking, thereby avoiding accidents when the medicine pot is lifted and dumped and interference when the pressing net is sunk.

[0044] In order to allow the Chinese medicine pieces to be fully soaked, the decoction table of this embodiment is provided with a vertical rod extending upward on one side corresponding to each soaking position, the end of the vertical rod extends toward the positioning frame and is provided with a telescopic cylinder, the output end of the telescopic cylinder is provided with a pressing net, the center of the pressing net is aligned with the positioning center of the positioning frame. The positioning frame enters the designated position of the soaking position after the medicine pot is filled with water, and the size of the pressing net of this embodiment is similar to the size of the inner wall of the medicine pot, so that the pressing net can basically sink the floating pieces of boiled medicine into the water when it sinks, so that the Chinese medicine pieces of boiled medicine are fully soaked.

[0045] Furthermore, a lifting medicine pouring device is provided at the designated position positioned by the positioning frame, so that the medicine pot on the soaking position is lifted and poured into the medicine pot on the decoction position under the action of the lifting medicine pouring device. That is to say, the medicine pot on the soaking position can pour the soaked medicine juice and medicinal materials in the medicine pot into the medicine pot on the decoction position through the lifting medicine pouring device. In addition to limiting the transmission position of the medicine pot on the soaking conveyor belt, the positioning frame also provides positioning, so that it is limited to the designated position to meet the operation of the lifting medicine pouring device just to lift the medicine pot and pour it onto the medicine pot at the decoction position. It should be noted that this embodiment does not impose any form of limitation on the lifting medicine pouring device, and the technicians can set it according to actual use needs. It can be a right-angle flip structure, the bottom surface supports the medicine pot, and the side surface provides support when the medicine pot is flipped and flipped. It can also be a flip frame acting on the fulcrums on both sides of the medicine pot, etc., as long as the medicine pot can be flipped through the lifting and dumping related structures and the medicine juice and other materials in the pot are poured into the decoction position when dumping at the designated position limited by the positioning frame.

[0046] Through the above structure, after the medicine pot coming out of the adjustment station 600 is filled with water by the water adding station, at least one decoction station is carried out according to several branches. The decoction station integrates multiple decoction points, which greatly improves the decoction efficiency. The decoction points can meet the requirements of soaking loose pieces and decocting first and then adding in the decoction of traditional Chinese medicine. Through the coordinated use of the soaking position and the decoction position, automatic and rapid decoction can be achieved, which can reduce manual intervention and improve efficiency.

[0047] Those skilled in the art can understand that, in the dispensing station before the water adding station, the operator classifies the different Chinese medicine decoction pieces in the prescription by obtaining the prescription information and places them in different medicine pots. In the actual application scenario, the Chinese medicine in the prescription is generally decocted after soaking in one pot, and some are soaked in two pots and decocted first and then added. A few are soaked separately in a third pot according to different soaking times. The decoction method of each prescription can determine the soaking time, water injection volume and decoction process of each subsequent medicine pot when adjusting. Therefore, in this embodiment, after the dispensing station, how many medicine pots are used for soaking and decocting for a prescription, the related water injection volume information and soaking time and decoction process have been associated and bound through the unique code of the medicine pot, and the subsequent process can call the relevant pre-set information by scanning the barrel body logo of the medicine pot.

[0048] In an optional embodiment, the water adding station 400 includes a positioning sensor 410 for sensing the medicine pot in place, a water adding scanner 420 for scanning the label on the medicine pot barrel, and a water adding pipe 430 for injecting water into the medicine pot. The medicine pot is positioned after being sensed by the positioning sensor on the conveyor line, and the label on the medicine pot barrel is identified by the water adding scanner to obtain the prescription information associated with the current medicine pot and the information of the medicinal materials placed through the dispensing station and the corresponding water injection amount information. The water adding pipe is controlled by the water adding control module to add water to the medicine pot in a quantitative manner according to the water injection amount information.

[0049] In an optional implementation, the conveyor line is located between the water adding station 400 and the decoction station 300 and has a decoction scanner 330. After the decoction scanner 330 identifies the passing medicine pot barrel body mark, it obtains the idle decoction point on the current decoction station, determines the decoction table position according to the idle decoction point, and controls the medicine pot to enter the branch conveyor line of the decoction table. A decoction sub-scanner 340 is provided at the front end of the branch conveyor line, which is used to scan the passing medicine pot barrel body mark and then form feedback to the conveyor line, and is used to determine the number of medicine pots required for the current prescription according to the acquired prescription information and judge whether the soaking position is idle, thereby controlling the current medicine pot to enter the soaking position.

[0050] In order to better understand the structure of the automatic rapid decoction device, the control process of the automatic rapid decoction device is described below in conjunction with an embodiment, but it is not intended to limit the technical solution of the embodiment of the present invention. On the basis of one or more of the above embodiments, this embodiment includes:

[0051] refer to Figure 1 and Figure 2 The decoction scanner 330 scans the barrel mark of the passing medicine pot, classifies and controls the medicine pots, allocates one or more medicine pots of the same prescription to the same decoction point, calls the idle status information of the decoction point on the decoction table, and makes effective allocation to avoid blockage of the conveyor line and the decoction process, thereby improving the utilization rate and decoction efficiency of the decoction table.

[0052] It should be noted that the medicine pot in this embodiment adopts a circular barrel body design, and its barrel body logo can be set to be evenly arranged in a circle around the barrel body, so that the barrel body logo of the medicine pot can be obtained by scanning the barrel body of the medicine pot from any position on the side, that is, the QR code. By setting multiple identical QR codes around the barrel body, the medicine pot can be scanned by the scanner as a QR code during the transmission process.

[0053] After being allocated, the medicine pot enters the branch conveyor line 200. After the decoction sub-scanner 340 scans the body mark of the medicine pot passing by, the prescription information associated with the current medicine pot is obtained and the number of medicine pots required for the current prescription is determined. When the number of medicine pots required for the prescription is less than or equal to two, the branch conveyor line 200 directly conveys the medicine pot to the soaking position 311 of the same decoction point. When the number of medicine pots required for the prescription is greater than two, it is determined that the current medicine pot belongs to the front decoction process or the back decoction process in the front decoction and back decoction process. The front decoction and back decoction process pre-sets the decoction order in the adjustment process and forms an association through the body mark of the medicine pot;

[0054] If it is a pre-decoction process, determine whether the soaking position of the designated decoction point is free: if it is free, directly enter the free soaking position through the soaking conveyor belt; if it is not free, control the hanging lifting frame to put the medicine pot of the pre-decoction process of one of the soaking positions into the steam heating port to make the soaking position free;

[0055] If it is a later process, it enters the frying standby area 350.

[0056] That is to say, if the soaking position of the decoction point is full, the medicine pot of one of the front decoction processes is controlled to enter the decoction position, so that the soaking position is vacant, and the medicine pots of the front decoction process on the branch conveyor line all enter the vacant soaking position. For better understanding, in the control of the following embodiment, when there is no medicine pot placed at the decoction position, two medicine pots of the subsequent process will not be placed at the two soaking positions to block the medicine pot of the front decoction process.

[0057] In an optional implementation, when the current medicine pot belongs to the latter process in the first decoction and then decoction process, the number of medicine pots in the first decoction process in the current prescription is determined:

[0058] If there are three or more medicine pots in the front-end decoction process, the current medicine pot will directly enter the standby area for decoction, and a manual intervention warning will be issued when the front-end decoction process starts;

[0059] If there are two medicine pots in the front decoction process, it is obtained whether there are medicine pots for the next process at the two immersion positions. If there are medicine pots for the next process, the current medicine pot directly enters the standby area for decoction, and a manual intervention warning is issued when the front decoction process starts. If there are no medicine pots for the next process, the branch conveyor line directly transfers the current medicine pot to the immersion position;

[0060] If the number of medicine pots in the front-decoction process is one, it is determined whether both immersion positions are idle. If both immersion positions are idle, the branch conveyor line directly transfers the current medicine pot to the immersion position.

[0061] If there is only one medicine pot in the pre-decocting process, when there is only one or no immersion position available, determine whether the medicine pot in the pre-decocting process has entered the decoction position:

[0062] If only one soaking position is free, and the medicine pot of the previous decoction process has entered the decoction position, the branch conveyor line will directly transfer the current medicine pot to the free soaking position. Otherwise, it will wait for the medicine pot of the previous decoction process to enter the decoction position before executing the next step;

[0063] If there is no vacant soaking position, when the medicine pot of the previous decoction process is in the soaking position, the hanging lifting frame is controlled to put the medicine pot of the previous decoction process into the decoction position to make the soaking position vacant; when the medicine pot of the previous decoction process is in the decoction position, the current medicine pot directly enters the standby area for decoction, and a manual intervention alarm is issued when the previous decoction process starts.

[0064] Obviously, the above embodiments are only used to illustrate the operation process of the automatic rapid decoction device, and are not intended to limit the scope of protection of the present invention. Without departing from the concept of the present invention, those skilled in the art can adjust the above structure and control so that the present invention can be applied to more specific application scenarios.

[0065] On the other hand, another embodiment of the present invention provides an automatic rapid decoction device for Chinese medicine decoction pieces, which can achieve automatic rapid decoction by executing the following steps, which can reduce manual intervention and improve efficiency. Although the following steps are described in order, some of the steps can be run independently or in reverse order. In this regard, without departing from the inventive concept, the technical solutions of the following steps running independently and / or in combination and after the order is disordered also belong to the embodiments of the present invention.

[0066] This embodiment includes a decoction control method, which uses an automatic rapid decoction device to perform the following steps:

[0067] The sensing signal of the positioning sensor passing through the water adding station is obtained. The sensing signal corresponds to the conveying plate to control the medicine pot to be positioned at the designated water adding position. The medicine pot barrel body mark is identified by the water adding scanner at the designated position to obtain the water injection amount information and control the quantitative water injection of the water adding pipeline;

[0068] The medicine pot coming out of the water adding station passes through the decoction scanner and obtains the water adding and decoction process information from the barrel body mark. Combined with the idle decoction points on the current decoction station, the decoction table position is determined according to the idle decoction points, and the medicine pot corresponding to the prescription is controlled to enter the branch conveyor line of the decoction table. The decoction sub-scanner before the branch conveyor scans the medicine pot barrel body mark and then forms feedback to the conveyor line;

[0069] The branch conveyor line transfers the medicine pot to the soaking side, and under the set control, it enters the soaking position through the soaking conveyor belt, and then the medicine pot on the soaking position is lifted by the lifting frame and placed in the decoction position, which includes:

[0070] like Figure 3As shown, the prescription information associated with the current medicine pot is obtained and the number of medicine pots required for the current prescription is determined. When the number of medicine pots required for the prescription is less than or equal to two, the branch conveyor line directly conveys the medicine pot to the soaking position of the same decoction point;

[0071] When the number of medicine pots required by the prescription is greater than two, determine whether the current medicine pot belongs to the front-decoction process or the back-decoction process in the front-decoction and back-decoction process:

[0072] If it is a pre-decoction process, determine whether the soaking position of the designated decoction point is free: if it is free, directly enter the free soaking position through the soaking conveyor belt; if it is not free, control the hanging lifting frame to put the medicine pot of the pre-decoction process of one of the soaking positions into the steam heating port to make the soaking position free;

[0073] If it is a later process, determine the number of medicine pots in the previous decoction process in the current prescription:

[0074] If there are three or more medicine pots in the front-end decoction process, the current medicine pot will directly enter the standby area for decoction, and a manual intervention warning will be issued when the front-end decoction process starts;

[0075] If there are two medicine pots in the front decoction process, it is obtained whether there are medicine pots for the next process at the two immersion positions. If there are medicine pots for the next process, the current medicine pot directly enters the standby area for decoction, and a manual intervention warning is issued when the front decoction process starts. If there are no medicine pots for the next process, the branch conveyor line directly transfers the current medicine pot to the immersion position;

[0076] If there is only one medicine pot in the front-decoction process, then check whether both immersion positions are free. If both immersion positions are free, the branch conveyor line directly transfers the current medicine pot to the free immersion position. If there is only one or no immersion position free, determine whether the medicine pot in the front-decoction process has entered the decoction position:

[0077] If only one soaking position is free, and the medicine pot of the previous decoction process has entered the decoction position, the branch conveyor line will directly transfer the current medicine pot to the free soaking position. Otherwise, it will wait for the medicine pot of the previous decoction process to enter the decoction position before executing the next step. At this time, when the medicine pot of the current decoction process enters the soaking position, it means that there is no soaking free position.

[0078] If there is no vacant soaking position, when the medicine pot of the previous decoction process is in the soaking position, the hanging lifting frame is controlled to put the medicine pot of the previous decoction process into the decoction position to make the soaking position vacant; when the medicine pot of the previous decoction process is in the decoction position, the current medicine pot directly enters the standby area for decoction, and a manual intervention alarm is issued when the previous decoction process starts.

[0079] In the medicine pot entering the decoction point, the immersion time of each medicine pot is obtained. The immersion time can be obtained through the prescription information when the decoction sub-scanner scans the corresponding medicine pot barrel body mark. In this regard, during the immersion process, since the medicine pot at the immersion position is accurately positioned, the pressure net is controlled by the telescopic cylinder to press down toward the medicine pot, so that the boiled and loose medicinal pieces are completely immersed in water.

[0080] When the medicine pots of all the pre-decoction processes meet the corresponding set soaking time, close the decoction cover and start the steam heater to decoct at the set temperature, pressure and decoction parameters. It should be noted that the set temperature, pressure and decoction parameters and other related decoction process information have been set by the operator in the prescription information or the dispensing station. When the decoction scanner scans the medicine pot barrel mark and determines the decoction point, the decoction point can be connected to complete the control of the subsequent decoction process.
