Description

Technical Field

[0001] The present invention relates to an intelligent Chinese medicine cabinet, in particular to a cutting-type bulk Chinese medicine decoction piece unit medicine cabinet (including stirring, crushing, conveying, and metering functions) that can automatically and intelligently complete the functions of adding medicine, taking medicine, and discharging medicine. Background Art

[0002] The traditional dispensing method of Chinese medicine is usually manual dispensing. That is, when a patient goes to the pharmacy to pick up medicine, the pharmacist directly goes to the corresponding drawer of the Chinese medicine cabinet to manually pick up, weigh, and prepare the prescription for the patient. This manual dispensing method has the disadvantages of low efficiency, easy to make mistakes, time-consuming and laborious.

[0003] Technicians in the field of Chinese medicine have proposed some solutions for the automation of Chinese medicine dispensing and dispensing. First, the "automatic Chinese medicine dispensing machine" (CN107200156): It consists of a weighing unit, a negative pressure collector, and a controller. The weighing unit consists of multiple weighing devices, a main medicine discharge pipe, and a temporary medicine discharge device. Weigh each Chinese medicine independently and use negative pressure to suck and collect the drugs to achieve centralized dispensing. Second, the "fully automatic sliced Chinese medicine intelligent medicine dispensing machine" (CN104828445): There are at least two columns of medicine dispensing units on the frame. The medicine dispensing unit consists of a medicine storage box, a linear motion module, a flipping feeding hopper, a linear feeding hopper, etc. It is controlled by a mechanical automation program and has the characteristics of accurate metering and fast dispensing speed.

[0004] None of the above technical solutions can centrally and automatically and intelligently complete all operations such as adding medicine, taking medicine (including stirring, crushing, conveying, and metering functions), and discharging medicine in a single unit medicine cabinet. Summary of the Invention

[0006] The purpose of the present invention is achieved as follows:

[0007] A cutting-type bulk Chinese medicine decoction piece unit medicine cabinet, the unit medicine cabinet is composed of a cabinet box and a hopper assembly. The hopper assembly is integrally formed by a hopper and an upper cover plate. The cuboid upper cover plate is buckled on the upper end surface of the opening at the top of the cabinet box, and the hopper extends into the inner cavity of the cabinet box. A dosing door with side baffles on both left and right sides is hinged at the dosing port in the front of the upper cover plate.

A material taking conveyor belt device and a cutting type medicine taking device are successively installed on the fixed base from bottom to top. A metering pushing and flipping device is installed on the bottom plate of the cabinet box below the discharge end of the material taking conveyor belt device. A rear door automatic opening and closing device is also arranged on the cabinet box.

[0009] The structure of the above-mentioned curved rod stirring device is as follows: The right bearing seat is fixed on the right outer wall of the lower opening of the hopper by bolts. The driving shaft is installed and fixed on the inner ring of the right bearing in the right bearing seat. The motor seat is fixed on the outside of the right bearing seat.

The driven shaft is installed and fixed on the inner ring of the left bearing in the left bearing seat. The left and right ends of the curved rod stirring shaft are respectively fixed on the driven shaft and the driving shaft by axle pins.

[0010] The structure of the material taking conveyor belt device arranged below the discharge port of the cutting type medicine taking device is as follows: The main body frame is composed of the horizontal top plate of the main body beam welded on the bottom surface of the horizontal bottom plate of the support beam. The main body beam is integrally composed of the horizontal top plate and two vertical plates extending downward at the left and right ends. The support beam is formed by two vertical plates extending upward from the left and right ends of the horizontal bottom plate and then extending left and right respectively to form the left and right top plates. The driving wheel component: A bearing is fixed at the left end of the axial through hole of the driving wheel. A bushing (501) with a D-shaped inner hole is movably sleeved at the right end of the axial through hole of the driving wheel. The D-shaped reduction motor shaft of the reduction box driven by the motor is sleeved and fixed in the inner hole of the bushing. The shaft support extends into the axial through hole of the driving wheel from the left end and is fixed on the inner ring of the bearing. A side plate is respectively fixed on the outer extending parts of the shaft support and the reduction motor shaft. The two side plates are used for being respectively fixed on the front parts of the two vertical plates of the main body beam by bolts. The driven wheel component: Bearings are respectively fixed at the left and right ends of the axial through hole of the driven wheel. The driven wheel shaft is installed and fixed on the inner rings of the two bearings. Outer side plates are respectively fixed on the two outer extending parts of the driven wheel shaft extending out of the driven wheel. The two outer side plates are used for being sleeved on the rotating shafts of the two vertical plates at the rear of the main body beam. The mesh belt coated with food-grade PU layer or rubber layer is sleeved on the driving wheel and the driven wheel, and the driven wheel component is fixed to the main body beam by rivets passing through the fixing holes on the two outer side plates of the driven wheel and the holes on the main body beam.

[0011] The structure of the above-mentioned cutting type medicine-taking device is as follows: on its outer circumference, a left cutter shaft and a right cutter shaft with several racks uniformly arranged along the axial direction are respectively installed between the front seat plate and the rear seat plate in parallel through bearings and bearing seats; the structure of the cutting blade is composed of a blade body, a cutting tool head and a spring supporting device. There is a central hole in the blade body, and tooth grooves formed by racks are evenly distributed on the circumference of the central hole. These tooth grooves are used to match with the racks on the cutter shaft to install the blade body on the cutter shaft. The outer shape of the blade body is a closed curve: the right curve is a nearly semi-circular arc or equal to a semi-circular arc formed by taking the center of the central hole and a larger radius and starting from the 270-degree point in the counterclockwise direction. The left curve is a larger semi-circular arc or equal to a semi-circular arc formed by taking a smaller radius and starting from the 270-degree point in the clockwise direction, and extends longitudinally to the end point of the right curve. And there is a card slot for the cutting tool head to be embedded at the adjacent position of the left curve and the right curve; the cutting tool head has a long cutting edge and a short cutting edge formed by inward depression and a V-shaped opening with one long and one short at the top formed by inward depression; the cutting tool head is embedded on the card slot of the blade body, and the top curve of the cutting tool head and the right curve of the blade body are both on the circumference of the same center; the structure of the spring supporting device is that the ejector rod is integrally composed of a disc-shaped large head and a round rod. There is a through hole on the cushion column. The spring is placed or fixed between the disc-shaped large head of the ejector rod and the cushion column. The spring supporting device is inserted into the through hole on the blade body. The rear arc surface of the cushion column coincides with the outer surface of the blade body, and then it is fixed on the blade body by a pin or a bolt through the fixing hole on the blade body and the through hole of the cushion column. And the round rod of the ejector rod extends into the concave notch formed by the long cutting edge and the short cutting edge of the cutting tool head movably;

[0012] The thickness of the shaft sleeve is the same as that of the cutting blade. Tooth grooves used for sleeving with the racks of the left and right cutter shafts are uniformly arranged on the inner circumference of the shaft sleeve; on the left cutter shaft and the right cutter shaft, starting from the same starting position, multiple cutting blades and the same number of shaft sleeves are alternately installed from front to back. The cutting blade and the shaft sleeve are respectively installed at the same starting positions of the left cutter shaft and the right cutter shaft. The same multiple cutting blades on the left cutter shaft and the right cutter shaft are respectively distributed in a spiral shape on two different semi-circumferences of the left and right cutter shafts; there is also a motor reduction device for driving the left and right cutter shafts to rotate inwardly in opposite directions: the motor gear on the reduction motor shaft, that is, the first driving gear, meshes and drives the first driven large gear. The second driving gear installed on the same shaft as the first driven large gear meshes with the second driven large gear on the left cutter shaft. Another gear on the left cutter shaft meshes with the gear on the same right cutter shaft and drives inwardly in opposite directions;

[0013] The multiple cutting blades on the left cutter shaft from front to back are installed on the upper half circumference surface of the left cutter shaft at the same deflection angle. The same multiple cutting blades on the right cutter shaft from front to back are installed on the lower half circumference surface of the left and right cutter shafts at the same deflection angle.

[0014] Compared with the prior art, the present invention has the following technical features and advantages

[0015] 1. Technical features of the cutting type medicine taking device:

[0016] ⑴ The cutting type medicine taking device is composed of a reduction motor, a reduction gear set, a reduction gear set cover plate, a front seat plate of the cutter shaft, a rear seat plate of the cutter shaft, a cutting tool holder, a cutting auxiliary tool holder, bearings, a cutting cutter shaft, a bushing, cutting blades, and slag scraping blades.

[0017] ⑵ The cutting auxiliary tool holder is fixed on the cutting tool holder, with a distance equivalent to that of one cutting blade between them. Its outer shape is like a rake. When the cutting type medicine taking device is assembled, the cutting auxiliary tool holder corresponds to the position of the bushing on the cutting blade group and covers the bushing on the cutting blade group.

[0018] ⑶ The cutting cutter shaft, the bushing, and the cutting blades are assembled to form a cutting blade group. The cutting blades and the bushings are assembled at intervals on the cutting cutter shaft, and the cutting blades are arranged in a spiral shape on the cutting cutter shaft. The cutting blade at the spiral tail does not exceed the starting cutting blade. Thus, when the cutting blade group rotates one circle, all the cutting blades can perform a cutting and crushing operation once.

[0019] ⑷ The cross section of the cutting cutter shaft is in the shape of a gear, with equally spaced racks evenly distributed on its surface. The pitch of the racks matches the rotation angle of the cutting blades arranged in a spiral shape in the cutting blade group. Racks corresponding to the racks on the cutter shaft are distributed on the middle holes of the cutting blades. Thus, when the cutting blades are installed on the cutting cutter shaft, they can be installed according to the deflection angle of the spiral arrangement between the front and rear cutting blades required by the design. Racks corresponding to the racks on the cutter shaft are distributed on the middle holes of the bushings, which can make the bushings rotate together with the cutting cutter shaft.

[0020] ⑸ Two cutting blade groups are installed in one cutting type medicine taking device, and they are installed in the cutting type medicine taking device in such a way that the cutting edge of one blade group faces the back of the other blade group. When the cutting device operates, one cutting blade group starts to cut after the other cutting blade group has finished cutting. The semi-circular spiral arrangement of each blade group allows the blades to contact the medicinal slices in a set order successively to cut the medicinal slices. In this way, the number of blades contacting the medicinal slices is the least and the cutting resistance is the smallest during each cutting. The blades of one cutting blade group correspond to the bushings of the other cutting blade group. When the reduction motor operates, both cutting blade groups rotate inwards towards each other. The blades of one cutting blade group use the cutting auxiliary tool holder above the bushings of the other cutting blade group and the blades on both sides as the tool holder to cut the medicinal slices.

[0021] ⑹. The cutting edge of the cutting blade is V-shaped, with one side of the V being long and the other short. When cutting medicinal herb slices, the long side of the cutting edge contacts and cuts the medicinal herb slices first, and the short side contacts and cuts the medicinal herb slices later. This can effectively reduce the stress on the cutting blade and save power consumption. Since the woody fibers of the medicinal herb slices of liana plants are heavy and tend to clog the cutting edge, a spring support device is provided inside the cutting edge to prevent the cut and small medicinal herb slices from clogging the cutting edge.

[0022] ⑺. Since the reduction ratio of a conventional reduction motor cannot reach the required rotational speed and will also reduce the transmission force, therefore, a reduction gear set design is adopted, which can not only meet the rotational speed requirement after reduction but also maintain the transmission force.

[0023] ⑻. The slag scraping blade can effectively prevent the cut and small medicinal herb slices from adhering to the shaft sleeve and prevent the cutting blade group from being blocked.

[0024] 2. Independence: A single-unit medicine cabinet is an independent entity. As long as the external power supply and communication network are connected, it can independently complete the tasks of adding medicine, dispensing medicine, and discharging medicine.

[0025] 3. One-key connection mode: The wire groove on the cabinet is a reserved channel for connecting the power cord and communication line outside the cabinet for the single-unit medicine cabinet. Through the pluggable terminal in the wire groove, the one-key connection mode for the single-unit medicine cabinet to be powered on and communicate can be realized.

[0026] 4. High adaptability: By matching different models of hoppers, cutting-type medicine dispensing devices, and stirring devices, it can adapt to the changes in the shape and bulk density of medicinal herb slices and complete the task of dispensing different medicinal herb slices.

[0027] 5. Modularity: Various devices inside the single-unit medicine cabinet, such as the curved rod stirring device, cutting-type medicine dispensing device, material taking conveyor device, metering pushing and flipping, metering correction device, rear door device, medicine adding door, cabinet front door, etc., all adopt modular design and have relatively independent functions. If a certain device fails, it can be replaced separately, thus realizing fast replacement and repair.

[0028] 6. Good sealing performance: Taking the single-unit medicine cabinet as an independent space, all joints are sealed. The opening and closing interfaces of the frequently opened devices such as the medicine adding door, cabinet front door, rear door device, and upper cover plate are sealed with rubber strips, making the single-unit medicine cabinet box form a closed space and having a good effect of preventing insects and rodents.

[0029] 7. Precise medicine dispensing: The high-torque motor in the cutting-type medicine dispensing device drives the cutting blade group to rotate uniformly. The cutting blades in the cutting blade group perform size reduction processing on the medicinal herb slices. Each time the cutting blade rotates one circle, size reduction processing is carried out on the medicinal herb slices. The outer dimensions and weights of the single medicinal herb slices after size reduction are basically the same, thereby improving the accuracy of medicine dispensing measurement and achieving the purpose of accurate medicine dispensing.

[0030] 8. High medicine dispensing efficiency: Select a high-torque reduction motor (either DC or AC motor can be selected). When the cutting blades in the cutting blade group rotate one circle, a relatively large amount of medicinal herb slices can be cut and reduced.

[0031] 9. Preventing the formation of material bridges: Through the operation of the curved rod stirring device in the hopper, it prevents the formation of material bridges of the medicinal herb slices in the hopper during the downward sliding process, enabling the medicinal herb slices to smoothly slide to the bottom of the hopper along with the medicine dispensing of the cutting-type medicine dispensing device.

[0032] 10. Self-cleaning ability: At the bottom of the material taking conveyor belt device, a cleaning brush strip is designed. As the conveyor belt rotates normally, the medicinal residues and dust attached to the conveyor belt can be swept to the medicinal residue outlet in the fixed base device through the cleaning brush strip and finally accumulate in the medicinal residue bag. Only the medicinal residues in the medicinal residue bag need to be cleaned regularly.

[0033] 11. Good heat dissipation: Ventilation mesh holes are provided at the position of the control circuit board corresponding to the front door of the cabinet, ensuring the heat dissipation of the control circuit board; an air intake mesh hole with a dust-proof net is provided at the rear end of the cabinet box, and a heat dissipation exhaust mesh hole is provided at the front end of the cabinet box. An exhaust fan is installed on the mesh hole. When the exhaust fan operates, fresh air enters from the air intake mesh hole at the rear end of the cabinet box, takes away the heat generated by the intermediate motor, and then discharges the hot air through the exhaust fan, thereby achieving the purpose of heat dissipation.

[0034] 12. High visibility of the operation status of the unit medicine cabinet: By observing the colors of the medicine shortage indicator light and the fault indicator light on the front door of the cabinet, the operation status of the unit medicine cabinet can be judged.

[0035] 13. Advantages of the split-type unit medicine cabinet: The split-type unit medicine cabinet can separate the hopper from the cabinet box. The hopper positioning pin on the hopper is assembled with the hopper positioning groove on the cabinet box for positioning, and then fastened to the hopper through the fixing holes on the cabinet box. Thus, the hopper and the cabinet box are easy to assemble and disassemble, facilitating the replacement of other types of hoppers without replacing the cabinet box.

[0036] 14. Preventing medicine spillage during medicine addition: Side baffles are provided on both sides of the medicine addition door to prevent the medicinal herb slices from accidentally falling outside the hopper during the medicine addition process; the side baffle of the medicine addition door is inserted into the baffle box of the medicine addition door, and a sealing brush strip is provided in the baffle box of the side baffle of the medicine addition door to prevent the medicinal herb slices from accidentally falling into the side baffle box.

[0037] 15. Pollution prevention: The control circuit board is covered with a control circuit board box, which isolates the connection between the control circuit board and the internal space of the cabinet, avoiding dust in the cabinet from polluting the control circuit board; during the process of dispensing Chinese herbal medicine pieces corresponding to some unit medicine cabinets, more medicine dust may be generated, polluting the inside of the unit medicine cabinet. To prevent this kind of medicine dust pollution, a dust-proof isolation board (or dust-proof isolation mesh cloth) can be set to divide the inside of the cabinet into two areas. The upper part is the heat dissipation area, and the lower part is the medicine dispensing area, reducing the space polluted by medicine dust. The two areas are isolated from each other and do not affect each other. The medicine dust generated in the medicine dispensing area with larger medicine dust will not pollute the heat dissipation area, and the medicine dispensing area is regularly cleaned during use.

[0038] 16. Manual unlocking available: The electric control locks of the front cabinet door and the medicine adding door are both designed with manual mechanical unlocking parts. In the case of the failure of the electric control lock, the front cabinet door and the medicine adding door can be opened by manual unlocking.

[0039] 17. Regular calibration of measurement error: A measurement calibration device is installed above the measurement pushing and flipping device corresponding to the unit medicine cabinet. The superior system can regularly control the measurement calibration device through the unit medicine cabinet control board to calibrate the measurement accuracy of the measurement pushing and flipping device, so as to ensure the measurement accuracy of the measurement pushing and flipping device.

[0040] (1) Stirring: The motor in the curved rod stirring device drives the curved stirring rod to rotate. When the curved stirring rod rotates, it stirs the Chinese herbal medicine pieces in the hopper, making the surface of the Chinese herbal medicine pieces slide along the central axis of the curved stirring rod towards the cutting type medicine dispensing device, so that the surface of the Chinese herbal medicine pieces is perpendicular to the blade of the cutting type medicine dispensing device, facilitating the cutting of the Chinese herbal medicine pieces by the cutting edge of the cutting type medicine dispensing device. At the same time, the operation of the curved rod stirring device can prevent the formation of a material bridge during the medicine dispensing process, avoiding the idling of the cutting type medicine dispensing device;

[0041] (2) Small and fragmented: There are two cutting blade groups installed in the cutting-type medicine-taking device, and they are installed in the cutting-type medicine-taking device in such a way that the cutting edge of one blade group faces the back of the other blade group. When the cutting device operates, one cutting blade group starts cutting after the other has finished cutting. The semi-circular spiral arrangement of each blade group allows the blades to contact the medicinal herb slices in a set order, cutting the medicinal herb slices. In this way, the number of blades in contact with the medicinal herb slices is minimized during each cut, and the cutting resistance is minimized. (Note: If all the cutting blades cut simultaneously, it will cause a large resistance, and the motor load of the cutting-type medicine-taking device will be very high. The cutting blades in the cutting blade group are arranged in a spiral shape, and the cutting blades cut the medicinal herb slices in a set order, which can effectively reduce the resistance when cutting the medicinal herb slices and reduce the motor load of the cutting-type medicine-taking device). When assembling the cutting-type medicine-taking device, the starting blade of the spiral blade group should face the metering and pushing device. This ensures that when the cutting-type medicine-taking device rotates, the small and fragmented medicinal herb slices cut by the starting blade of the blade group will first fall onto the conveyor belt of the material-taking conveyor belt device. As the blade group continues to rotate, the small and fragmented medicinal herb slices cut by the second blade, the third blade, and other subsequent blades will fall successively. However, it takes a certain amount of time for each blade to cut the small and fragmented medicinal herb slices. The small and fragmented medicinal herb slices that have fallen earlier have moved forward with the rotation of the conveyor belt of the material-taking conveyor belt device. In this way, the distance from the small and fragmented medicinal herb slices that have fallen after being cut by the previous blade is increased, ensuring that the small and fragmented medicinal herb slices that are cut first can be sent into the metering and pushing device first. (Note: If, when assembling the cutting-type medicine-taking device, the starting blade of the spiral blade group faces away from the metering and pushing device, when the cutting-type medicine-taking device rotates, the small and fragmented medicinal herb slices cut by the starting blade of the blade group will fall at the end of the conveyor belt of the material-taking conveyor belt device. As the conveyor belt of the material-taking conveyor belt device rotates towards the metering and pushing device, the small and fragmented medicinal herb slices cut by the starting blade will overlap and accumulate with the small and fragmented medicinal herb slices cut by the second blade, and then overlap and accumulate with the small and fragmented medicinal herb slices cut by the third blade, and so on. Overlap and accumulation will occur with the small and fragmented medicinal herb slices cut by subsequent blades, resulting in blockage of the material-taking conveyor belt device and affecting the operation of the cutting-type medicine-taking device and the material-taking conveyor belt device). The external dimensions and weights of the single-piece medicinal herb slices after being cut and fragmented are basically the same, thereby improving the accuracy of medicine-taking metering;

[0042] (3) Conveying: The rotation of the conveyor belt of the material-taking conveyor belt device is synchronized with the rotation of the cutting blade group in the cutting-type medicine-taking device, that is: every time the cutting blade group in the cutting-type medicine-taking device rotates one circle, the conveyor belt of the material-taking conveyor belt device also rotates one circle at the same time. This can ensure that the small pieces of cut medicinal materials can be timely sent into the metering and pushing device, and can also ensure the coordination between the cutting-type medicine-taking device and the material-taking conveyor belt device, avoiding the accumulation or uneven distribution of the medicinal materials on the conveyor belt of the material-taking conveyor belt device, thus affecting the accuracy of metering;

[0043] (4) Metering: The small pieces of cut medicinal materials are conveyed by the conveyor belt of the material-taking conveyor belt device and fall into the weighing pan in the metering, pushing and flipping device. When the weight of the medicinal materials in the weighing pan is greater than or equal to the set value of rough medicine-taking metering, the control board controls the cutting-type medicine-taking device and the material-taking conveyor belt device to start decelerating the cutting of small pieces of medicinal materials for medicine-taking until the required weight is reached, and all devices stop running and wait for medicine output.

[0044] 18. Medicine output:

[0045] (1) After the control system receives the medicine output instruction sent by the superior system, the control board controls the motor in the rear door device to rotate outward, and drives the connecting rod and the sensor dial to rotate outward. The connecting rod pushes up the upper sealing plate of the rear door and drives the lower sealing plate of the rear door to open. When the sensor dial rotates to a certain angle, the sensor dial touches the rear door limit sensor, and the motor stops rotating, and the rear door device remains in the open state.

[0046] (2) While the control board controls the action of the rear door device, it controls the operation of the metering, pushing and flipping device. The motor in the metering, pushing and flipping device starts to rotate, pushing the weighing pan backward. After moving horizontally for a certain distance, the gear on the weighing pan turntable meshes with the rack, so that the weighing pan has a flipping motion on the basis of horizontal movement and starts to pour out the medicinal materials until the weighing pan flips to a certain angle and touches the limit switch, then the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal materials can be completely poured out.

[0047] (3) After the weighing pan maintains the dumping angle for a certain period of time, the control board controls the motor in the metering, pushing and flipping device to start rotating in the reverse direction. The weighing pan rotates back to the horizontal state, and then moves horizontally back. After touching the limit switch, the motor stops rotating and the weighing pan resets.

[0048] (4) After the metering, pushing and flipping device resets, the control board controls the motor in the rear door device to rotate inward, and drives the connecting rod and the sensor dial to rotate inward. The connecting rod drives the upper sealing plate and the lower sealing plate of the rear door to rotate and close. When the sensor dial rotates back to a certain angle, the sensor dial touches the rear door reset sensor, and the motor stops rotating, and the rear door device is in the closed state.

[0134] The metering and calibration method of the metering and calibration device includes the following steps:

[0135] (1) The control system issues a "metering and calibration" command;

[0136] (2) The control board of the unit medicine cabinet controls the metering pushing and flipping device to zero the weighing pan metering;

[0137] (3) The control board of the unit medicine cabinet controls the motor of the metering and calibration device to work, driving the spring wire winding rod and the weight wire winder to rotate;

[0138] (4) The weight wire winder releases the weight wire to gently lower the weight. At the same time, the weight releases and resets the touch switch, and the control board of the unit medicine cabinet detects that the weight has moved;

[0139] (5) While the weight is moving, the spring wire winding rod retracts the spring wire, pulls out the spring wire in the spring disk, turns through the pulley, passes through the small hole at one end of the spring piece, and is wound into the wire groove in the spring wire winding rod;

[0140] (6) The weight continues to descend until it falls into the weighing pan of the metering pushing and flipping device. The weight is no longer subject to any pulling force. The motor continues to work for a certain period of time and then stops. The weight wire winder continues to rotate for a certain period of time to release some additional weight wire, making this additional part of the weight wire hang in the air so as not to affect the accuracy of the weight; the length of "the motor continues to work for a certain period of time" is controlled by the positioning section on the spring wire and needs to be set in advance;

[0141] (7) After the weight falls into the weighing pan of the metering pushing and flipping device, the positioning section fixed on the spring wire, passing through the pulley, reaches the spring piece. Since the positioning section is larger than the small hole of the spring piece, when the spring wire continues to be retracted, it will deflect the spring piece, and the spring piece will press the dial of the weight in-place touch switch. The control board of the unit medicine cabinet detects that the weight reaches the predetermined position and controls the motor to stop rotating;

[0142] (8) When the weight of the specified weight of the metering calibration device falls into the scale pan of the metering push flip device, the metering device of the metering push flip device will read the metering data of the weight in the current scale pan and send it to the unit medicine cabinet control board. The unit medicine cabinet control board compares the metering data with the weight data of the weight entered in advance. If the comparison error is within the specified error range, the metering device of the metering push flip device is determined to be qualified. If the comparison error exceeds the specified error range, the metering device of the metering push flip device is unqualified, and the unit medicine cabinet control board alarms the superior system, prompting that the metering device in the metering push flip device needs to be replaced;

[0143] (9) The control system controls the metering push device to automatically control the motor to rotate in the opposite direction after the metering calibration is completed. The weight line winder reels in the weight line to lift the weight, and the winding line rod releases the winding line. The winding line is pulled by the spring and wound into the spring disk. The positioning node goes back with the spring line, and the spring sheet rebounds to release the weight in place to touch the switch. The control system detects that the weight starts to return;

[0144] (10) The weight continues to rise and enters the weight reset fixing seat, the weight is fixed, and the paddle of the weight reset touch switch is pressed. The control method of the metering push flip device includes the following steps:

[0145] (1) Before weighing, the upper system controls the electronic scale control circuit board to reset the measurement data to zero;

[0146] (2) The weighing pan receives the medicinal material pieces output by the medicine dispensing device;

[0147] (3) The electronic scale sensor under the scale pan detects the weight of the medicinal materials in the scale pan in real time, and uploads the weight data to the upper system through the electronic scale control circuit board in real time;

[0148] (4) When the weight of the medicinal material slices reaches the required weight, the material taking device stops taking out the material, and the metering and pushing flipping device waits for the next action instruction;

[0149] (5) When the metering, pushing, and flipping device receives the dumping command sent by the superior system, the motor of the metering, pushing, and flipping device drives the screw rod to rotate, pushing the T-shaped flange nut to move. The T-shaped flange nut drives the slider to move linearly on the slide rail. The slider is connected to the scale plate turntable, and the slider drives the scale plate turntable to move linearly, thereby driving the scale plate to move linearly. When the scale plate moves to a certain position, the gear on the scale plate turntable meshes with the rack, enabling the scale plate to have a flipping motion on the basis of the linear motion. When the scale plate moves linearly to the specified position, the limit lever touches the limit touch switch and stops moving. At this time, the flipping motion of the scale plate just flips the scale plate to a certain angle, causing the medicinal herbal pieces in the scale plate to pour out, completing the medicine dispensing. After the scale plate stays in the dumping state for a few seconds, the motor rotates in the reverse direction, driving the scale plate to first rotate and fall back to the horizontal state, and then move linearly back to the initial starting point. The motor stops operating after the limit lever touches the reset touch switch.

[0150] (6) The scale plate resets, the scale plate metering is cleared, and it waits for the next operation.

[0158] Working process

[0159] 1. Medicine adding:

[0160] (1) The control board receives the medicine adding door unlocking instruction sent by the superior system. The control board controls the electro - lock of the medicine adding door to be powered on and unlocked. The medicine adding door automatically pops up and opens under the action of the spring plate and remains in the open state.

[0161] (2) The user loads the medicinal herb slices into the hopper.

[0162] (3) The user manually closes the medicine adding door, and the medicine adding is completed.

[0163] 2. Medicine fetching:

[0164] After the control board receives the medicine picking instruction sent by the superior system, the control board controls the curved rod stirring device to start stirring, controls the cutting - type medicine fetching device to start running, controls the material fetching conveyor device to start running, and controls the metering pushing and flipping device to start metering.

[0165] (1) Stirring: The motor in the curved rod stirring device drives the curved stirring rod to rotate. When the curved stirring rod rotates, it stirs the medicinal herb slices in the hopper, causing the surface of the medicinal herb slices to slide along the central axis of the curved stirring rod towards the cutting - type medicine fetching device, so that the surface of the medicinal herb slices is perpendicular to the blade of the cutting - type medicine fetching device, facilitating the cutting of the medicinal herb slices by the cutting edge of the cutting - type medicine fetching device. At the same time, the operation of the curved rod stirring device can prevent the formation of a material bridge during the medicine fetching process and avoid the idling of the cutting - type medicine fetching device;

[0166] (2) Small and fragmented: There are two cutting blade groups installed in the cutting-type medicine-taking device, and they are installed in the cutting-type medicine-taking device in such a way that the cutting edge of one blade group faces the back of the other blade group. When the cutting device operates, one cutting blade group starts cutting after the other has finished cutting. The semi-circular spiral arrangement of each blade group allows the blades to contact the medicinal material slices in a set order, cutting the medicinal material slices. In this way, the number of blades in contact with the medicinal material slices is minimized during each cut, and the cutting resistance is minimized. (Note: If all the cutting blades cut simultaneously, it will cause a large resistance, and the motor load of the cutting-type medicine-taking device will be very large. The cutting blades in the cutting blade group are arranged in a spiral shape, and the cutting blades cut the medicinal material slices in a set order, which can effectively reduce the resistance when cutting the medicinal material slices and reduce the motor load of the cutting-type medicine-taking device). When assembling the cutting-type medicine-taking device, the starting blade of the spiral blade group should face the metering and pushing device, so as to ensure that when the cutting-type medicine-taking device rotates, the small and fragmented medicinal material slices cut by the starting blade of the blade group can first fall on the conveyor belt of the material-taking conveyor belt device. As the blade group continues to rotate, the small and fragmented medicinal material slices cut by the second blade, the third blade, and other subsequent blades will fall one after another. However, it takes a certain amount of time for each blade to cut the small and fragmented medicinal material slices. The small and fragmented medicinal material slices that have fallen earlier have moved forward with the rotation of the conveyor belt of the material-taking conveyor belt device. In this way, the distance from the small and fragmented medicinal material slices that have fallen after being cut by the previous blade is increased, so as to ensure that the small and fragmented medicinal material slices that are cut first can be sent into the metering and pushing device first. (Note: If, when assembling the cutting-type medicine-taking device, the starting blade of the spiral blade group faces away from the metering and pushing device, when the cutting-type medicine-taking device rotates, the small and fragmented medicinal material slices cut by the starting blade of the blade group will fall at the end of the conveyor belt of the material-taking conveyor belt device. As the conveyor belt of the material-taking conveyor belt device rotates towards the metering and pushing device, the small and fragmented medicinal material slices cut by the starting blade will overlap and accumulate with the small and fragmented medicinal material slices cut by the second blade, and then overlap and accumulate with the small and fragmented medicinal material slices cut by the third blade, and so on. Overlap and accumulation will occur with the small and fragmented medicinal material slices cut by subsequent blades, which will cause blockage of the material-taking conveyor belt device and affect the operation of the cutting-type medicine-taking device and the material-taking conveyor belt device). The external dimensions and weights of the single-piece medicinal material slices after being cut and fragmented are basically the same, so as to improve the accuracy of medicine-taking metering;

[0167] (3) Conveying: The rotation of the conveyor belt of the material taking conveyor belt device is synchronized with the rotation of the cutting blade group in the cutting type medicine taking device, that is: every time the cutting blade group in the cutting type medicine taking device rotates one circle, the conveyor belt of the material taking conveyor belt device also rotates one circle at the same time. This can ensure that the cut and crushed medicinal material pieces of the cutting type medicine taking device can be timely sent into the metering and pushing device, and can also ensure the coordination between the cutting type medicine taking device and the material taking conveyor belt device, avoiding the accumulation or uneven distribution of the medicinal material pieces on the conveyor belt of the material taking conveyor belt device, so as not to affect the accuracy of metering;

[0168] (4) Metering: The cut and crushed medicinal material pieces are conveyed by the conveyor belt of the material taking conveyor belt device and fall into the weighing pan in the metering, pushing and flipping device. When the weight of the medicinal material pieces in the weighing pan is greater than or equal to the rough medicine taking metering set value, the control board controls the cutting type medicine taking device and the material taking conveyor belt device to start decelerating to cut and take the crushed medicinal material pieces until the required weight is reached, and all devices stop running and wait for the medicine to be discharged.

8. A control method for the control board of the unit medicine cabinet according to any one of claims 1 to 7, characterized in that, It includes the following steps: Medicine adding: (1) The control board receives the medicine adding door unlocking instruction sent by the superior system, and the control board controls the electric lock of the medicine adding door to be powered on and unlocked. The medicine adding door automatically pops up and opens under the action of the spring piece and remains in the open state; (2) The user loads the medicinal herb slices into the hopper; (3) The user manually closes the medicine adding door, and the medicine adding is completed; Medicine taking: After the control board receives the medicine picking instruction sent by the superior system, the control board controls the curved rod stirring device to start stirring, controls the cutting type medicine taking device to start running, controls the material taking conveyor device to start running, and controls the metering pushing and flipping device to start metering; (1) Stirring: The motor in the curved rod stirring device drives the curved stirring rod to rotate. When the curved stirring rod rotates, it stirs the medicinal herb slices in the hopper, making the plate surface of the medicinal herb slices slide along the central axis of the curved stirring rod towards the cutting type medicine taking device, so that the plate surface of the medicinal herb slices is perpendicular to the blade of the cutting type medicine taking device, facilitating the cutting of the medicinal herb slices by the cutting edge of the cutting type medicine taking device; at the same time, the operation of the curved rod stirring device can prevent the formation of a material bridge of the medicinal herb slices during the medicine taking process and avoid the idling of the cutting type medicine taking device; (2)Fragmentation: There are two cutting blade groups installed in the cutting type medicine taking device, and they are installed in the cutting type medicine taking device in such a way that the cutting edge of one blade group faces the back of the other blade group; when the cutting device operates, one cutting blade group starts cutting after the other cutting blade group has finished cutting; the semi-circular spiral arrangement of each blade group enables the blades to contact the medicinal herb slices in a set order, cutting the medicinal herb slices. In this way, each time of cutting, the number of blades contacting the medicinal herb slices is the least, and the cutting resistance is the smallest; if all the cutting blades cut simultaneously, it will cause a great resistance and the motor load of the cutting type medicine taking device will be very large; the cutting blades in the cutting blade group are arranged in a spiral shape, and the cutting blades cut the medicinal herb slices in a set order, which can effectively reduce the resistance when cutting the medicinal herb slices and reduce the motor load of the cutting type medicine taking device; when assembling the cutting type medicine taking device, the starting blade of the spiral blade group should face the metering and pushing device, so as to ensure that when the cutting type medicine taking device rotates, the medicinal herb slices cut by the starting blade of the blade group can first fall on the conveyor belt of the material taking conveyor belt device. As the blade group continues to rotate, the medicinal herb slices cut by the subsequent blades fall successively. However, each blade needs a certain time to cut the medicinal herb slices into small pieces. The medicinal herb slices cut into small pieces and fallen by the previous blade have moved forward with the rotation of the conveyor belt of the material taking conveyor belt device, so that the distance from the medicinal herb slices cut into small pieces and fallen by the subsequent blade is widened. In this way, it can be ensured that the medicinal herb slices cut into small pieces first can be sent into the metering and pushing device first; if when assembling the cutting type medicine taking device, the starting blade of the spiral blade group faces away from the metering and pushing device, when the cutting type medicine taking device rotates, the medicinal herb slices cut by the starting blade of the blade group will fall at the end of the conveyor belt of the material taking conveyor belt device. As the conveyor belt of the material taking conveyor belt device rotates towards the metering and pushing device, the medicinal herb slices cut into small pieces by the starting blade will overlap and pile up with the medicinal herb slices cut into small pieces by the second blade, and then overlap and pile up with the medicinal herb slices cut into small pieces by the third blade, and so on, and there will be overlap and piling up with the medicinal herb slices cut into small pieces by the subsequent blades, which will cause blockage of the material taking conveyor belt device and affect the operation of the cutting type medicine taking device and the material taking conveyor belt device; the external dimensions and weights of the single medicinal herb slices after being cut into small pieces are basically the same, so as to improve the accuracy of medicine taking metering; (3)Conveyance: The rotation of the conveyor belt of the material taking conveyor belt device is synchronized with the rotation of the cutting blade group in the cutting type medicine taking device, that is: every time the cutting blade group in the cutting type medicine taking device rotates one circle, the conveyor belt of the material taking conveyor belt device also rotates one circle at the same time; thus, it can not only ensure that the medicinal herb slices cut into small pieces by the cutting type medicine taking device can be timely sent into the metering and pushing device, but also ensure the coordination between the cutting type medicine taking device and the material taking conveyor belt device, avoiding the accumulation or uneven distribution of the medicinal herb slices on the conveyor belt of the material taking conveyor belt device, so as not to affect the accuracy of metering; (4)Measurement: The small cut medicinal material pieces are conveyed by the conveyor belt of the material taking conveyor belt device and fall into the weighing pan of the metering pushing and flipping device. When the weight of the medicinal material pieces in the weighing pan is greater than or equal to the rough medicine taking metering set value, the control board controls the cutting type medicine taking device and the material taking conveyor belt device to start decelerating and cutting the small cut medicinal material pieces for medicine taking until the required weight is reached, and all devices stop running and wait for medicine discharging.
