[0010] A rear door automatic opening and closing device is arranged at the medicine outlet of the rear vertical plate of the cabinet.

[0011] Compared with the prior art, the present invention has the following technical features and advantages:

[0012] 1. Independence: One unit medicine cabinet is an independent individual. As long as the external power supply and communication network are connected, it can independently complete the functions of adding medicine, taking medicine and discharging medicine.

[0013] 2. One-key connection mode: The wire groove on the cabinet is a reserved channel for connecting the power supply line and communication line outside the cabinet for the unit medicine cabinet. Through the pluggable terminal in the wire groove, the one-key connection mode for the unit medicine cabinet to be powered on and communicate can be realized.

[0014] 3. Adaptability: The unit medicine cabinet for bulk Chinese herbal medicine slices with upper discharge on the composite conveyor belt type double hopper is applicable to Chinese herbal medicine slices such as rhizoma sparganii, alisma orientale, and typhonium giganteum with a single slice weight greater than 1 gram, and usually the single slice weight is in the range of 3 - 5 grams. Through the medicine extraction plan where the Chinese herbal medicine slices in the fine medicine extraction part are pretreated by crushing and the Chinese herbal medicine slices in the rough medicine extraction part still maintain their original shape, the requirements for the management of Chinese herbal medicine slices in the Chinese medicine pharmacy and the provisions of the national pharmacopoeia can be fully met. There are many types of Chinese herbal medicine slices such as rhizoma sparganii, alisma orientale, and typhonium giganteum. Therefore, the unit medicine cabinet for bulk Chinese herbal medicine slices with upper discharge on the composite conveyor belt type double hopper has a wide range of applicability.

[0015] 4. Modularity: All kinds of devices in the unit medicine cabinet, such as the upper discharge medicine taking device, stirring device, metering pushing and flipping, metering correction device, rear door device, medicine adding door, cabinet front door, etc., adopt modular design and have relatively independent functions. If a certain device fails, it can be replaced separately, thus realizing rapid replacement and repair. Especially, the card strip of the upper discharge medicine taking device cooperates with the card slot on the hopper, and the design method of positioning and fixing the two components with locking screws and locking holes realizes the rapid installation, disassembly and positioning of the upper discharge medicine taking device.

[0016] 5. Good sealing performance: Taking the 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 unit medicine cabinet box body a closed space and having a good effect of preventing mosquitoes and insects.

[0017] 6. Fast and accurate medicine dispensing speed: For relatively large sheet-shaped medicinal materials such as rhizoma sparganii, rhizoma alismatis, and typhonii rhizome, by adopting a dual-hopper mode, one hopper contains unprocessed and non-crushed medicinal materials. Since the weight of each single-piece medicinal material is 3-5 grams, the weight of each piece of medicinal material taken out by the composite conveyor belt is relatively large. There are multiple rows of cylindrical pins on the composite conveyor belt, and each time it rotates one circle, multiple pieces of medicinal materials can be taken out. Therefore, the medicine dispensing speed of the rough separation hopper is very fast; the other hopper contains preprocessed and crushed medicinal materials, and the weight of each single piece of the preprocessed and crushed medicinal materials is less than 1 gram, which can fully ensure the accuracy of precise medicine dispensing. First, take out the uncrushed medicinal materials to ensure the medicine dispensing speed, and then take out the crushed medicinal materials to ensure the medicine dispensing accuracy. The combination of the two hoppers for medicine dispensing satisfies both the speed and the accuracy of medicine dispensing; moreover, the upper discharging medicine taking device (coarse) and the upper discharging medicine taking device (fine) adopt a special composite conveyor belt. Through the careful design of the width of the composite conveyor belt, the height of the steel belt pins, the spacing between the steel belt pins, and the upward slope of the upper discharging medicine taking device, and then through the action of the limited spring piece and the inner material cover, the excess medicinal materials are blocked in the hopper, ensuring that only a certain amount of medicinal materials can be taken out during the medicine taking process of the upper discharging medicine taking device, so as to achieve the purpose of accurate medicine taking.

[0018] 7. Eliminate the phenomenon of material bridge: Through the operation of the stirring device in the hopper, prevent the medicinal materials in the hopper from forming a material bridge during the downward sliding process, so that the medicinal materials can smoothly slide to the bottom of the hopper along with the medicine taking of the upper discharging medicine taking device.

[0019] 8. Have self-cleaning ability: Inside the upper discharging medicine taking device, there is a cleaning scraper, which can sweep the medicinal residues and dust attached to the inside of the composite tape into the medicine residue cover through the material residue port and finally accumulate in the medicine residue bag. Only need to clean the medicinal residues in the medicine residue bag regularly.

[0020] 9. Good heat dissipation: There are ventilation mesh holes at the position of the control circuit board corresponding to the front door of the cabinet, which ensures the heat dissipation of the control circuit board; there is an air intake mesh hole with a dust-proof net at the rear end of the cabinet box, and a heat dissipation exhaust mesh hole is set 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 middle motor, and then discharges the hot air through the exhaust fan, so as to achieve the purpose of heat dissipation.

[0021] 10. The operating state of the unit medicine cabinet is obvious: By observing the colors of the medicine shortage indicator light and the fault indicator light on the front door of the cabinet, the operating state of the unit medicine cabinet can be judged.

[0022] 11. Advantages of the split-unit medicine cabinet: The split-unit medicine cabinet can separate the hopper from the cabinet box. The hopper positioning pin on the hopper is engaged with the hopper positioning groove on the cabinet box for positioning and assembly, and then fastened through the fixing holes on the cabinet box and the hopper. Thus, the hopper and the cabinet box can be easily disassembled and assembled, facilitating the replacement of other types of hoppers without replacing the cabinet box.

[0023] 12. Preventing medicine spillage during dosing: Side baffles are provided on both sides of the dosing door to prevent the medicinal herbal pieces from accidentally falling outside the hopper during the dosing process. The side baffle of the dosing door is inserted into the baffle box of the dosing door, and a sealing brush strip is provided inside the baffle box of the dosing door to prevent the medicinal herbal pieces from accidentally falling into the side baffle box.

[0024] 13. Preventing contamination: The control circuit board is covered with a control circuit board box, isolating the connection between the control circuit board and the internal space of the cabinet box, and avoiding the contamination of the control circuit board by the medicine dust inside the cabinet box. For some unit medicine cabinets, more medicine dust may be generated during the process of taking the corresponding medicinal herbal pieces, causing pollution to 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 box 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 contaminate the heat dissipation area, and the medicine dispensing area is regularly cleaned during use.

[0025] 14. Manual unlocking available: Both the electric control locks of the front cabinet door and the dosing door are designed with manual mechanical unlocking parts, and the front cabinet door and the dosing door can be opened manually through artificial means in case of the failure of the electric control locks.

[0026] 15. Regularly calibrating the metering error: A metering calibration device is installed above the metering pushing and flipping device corresponding to the unit medicine cabinet. The upper computer system can regularly control the metering calibration device through the control circuit board of the unit medicine cabinet to calibrate the metering accuracy of the metering pushing and flipping device, so as to ensure the metering accuracy of the metering pushing and flipping device.

[0074] A control method for the metering, pushing, and flipping device includes the following steps:

[0075] (1). Before the weighing operation, the superior system controls the metering data of the electronic scale control circuit board of the electronic scale to return to zero;

[0076] (2). The weighing pan receives the medicinal material slices output by the medicine taking device;

[0077] (3). The electronic scale sensor under the weighing pan real-time detects the weight of the medicinal material slices in the weighing pan, and uploads the weight data to the superior system through the electronic scale control circuit board in real time;

[0078] (4). After the weight of the medicinal material slices reaches the required weight, the material taking device stops taking out materials, and the metering, pushing, and flipping device waits for the next action instruction;

[0079] (5) 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 designated 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 herb slices 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;

[0080] (6) The scale plate resets, the scale plate metering is cleared, and it waits for the next operation.

[0081] The control method of the metering calibration device includes the following steps:

[0082] (1) The control system issues a "metering calibration" command;

[0083] (2) The unit medicine cabinet control board controls the metering, pushing and flipping device to clear the scale plate metering;

[0084] (3) The unit medicine cabinet control board controls the motor of the metering calibration device to work, driving the spring wire winding rod and the weight wire winder to rotate;

[0085] (4) The weight wire winder releases the weight wire and gently lowers the weight. At the same time, the weight releases the reset touch switch, and the unit medicine cabinet control board detects that the weight has moved;

[0086] (5) While the weight is moving, the spring wire winding rod retracts the spring wire, pulls out the spring wire in the spring coil, 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;

[0087] (6) The weight continues to descend until it falls into the scale plate 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, leaving this additional weight wire suspended so that it does not 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 preset in advance;

[0088] (7) After the weight falls onto the scale plate of the metering push-turn device, the positioning node fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning node is larger than the small hole of the spring sheet, the mainspring continues to be retracted, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor to stop rotating;

[0089] (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;

[0090] (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;

[0091] (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 system detects that the weight reaches the initial fixed position and controls the motor to stop rotating.

[0092] (11) Metrology calibration is completed.

[0104] Working process:

[0105] Medicine adding:

[0106] 1. When the control circuit board receives the unlocking instruction for the medicine adding door sent by the upper computer system, the control circuit board controls the medicine adding door electric lock 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.

[0107] 2. The user loads the same kind of cut Chinese herbal medicines into the corresponding hoppers according to whether they are pre-processed and small. The unprocessed and small cut Chinese herbal medicines are loaded into the coarse material hopper, and the pre-processed and small cut Chinese herbal medicines are loaded into the fine material hopper.

[0108] 3. The user manually closes the medicine adding door, and the medicine adding is completed.

[0109] Medicine taking:

[0110] Setting of precise medicine dispensing when taking medicine: When configuring the precise medicine dispensing setting quantity of the compound conveyor belt type double hopper upper discharging bulk Chinese herbal medicine slices unit medicine cabinet, the upper computer system shall set it according to the maximum single grain weight of the contained medicinal materials or the multiple of the maximum single grain weight.

[0111] After the control circuit board receives the medicine picking instruction issued by the upper computer system, the control circuit board controls the stirring device to start stirring, the control circuit board controls the metering push device to start metering, and the control circuit board controls the upper discharging and taking medicine device (coarse) to start action. The motor in the upper discharging and taking medicine device (coarse) drives the composite conveyor belt to rotate. The two side-by-side cylindrical pins on the composite conveyor belt take out the medicinal slices from the coarse hopper like hooks, pass through the limiting spring sheet and the inner material cover, and under the action of the limiting spring sheet and the inner material cover, the excess medicinal slices are blocked in the hopper, so that the baffle only takes out one or one medicinal slice under normal circumstances, so as to achieve the requirement of accurate measurement. The medicinal slices pass through the discharging cover and fall into the weighing pan in the metering push flipping device until the weight of the medicinal slices in the medicine pan in the weighing pan is greater than or equal to the coarse medicine measurement setting value (coarse medicine measurement setting value = planned medicine picking amount - fine medicine setting amount), and the upper discharging and taking medicine device (coarse) stops. Then, the control circuit board controls the upper discharging and taking medicine device (fine) to start jogging medicine. The motor in the upper discharging and taking medicine device (fine) drives the composite conveyor belt to rotate. The two side-by-side cylindrical pins on the composite conveyor belt take out the pre-processed small medicinal material slices from the subdivided hopper like hooks, and pass through the limiting spring sheet and the inner material cover. Under the action of the limiting spring sheet and the inner material cover, the excess small medicinal material slices are blocked in the hopper, so that the baffle only takes out one or one small medicinal material slice under normal circumstances, so as to achieve the requirement of accurate measurement. The small medicinal material slices pass through the discharging cover and fall into the scale pan in the metering push flip device until the actual total amount of medicine discharged (actual total amount of medicine discharged = actual coarse medicine amount + actual fine medicine amount) is greater than or equal to the planned medicine picking amount, and the upper discharging and taking medicine device (fine) stops moving. Then the metering push device stops metering, and the stirring device stops stirring. Complete this medicine picking task.

[0112] Dispensing medicine:

[0113] 1. After the control system receives the medicine dispensing command from the upper computer system, the control circuit 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 lifts 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, the motor stops rotating, and the rear door device remains open.

[0114] 2. While the control circuit board controls the operation of the rear door device, it also controls the operation of the metering push and flip device. The motor in the metering push and flip device starts to rotate, pushing the weighing pan towards the rear door. After moving horizontally for a certain distance, the gear on the weighing pan turntable meshes with the rack, causing the weighing pan to have a flipping motion in addition to the horizontal movement, and start to pour out the medicinal slices. When the weighing pan flips to a certain angle and touches the limit switch, the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal slices can be completely poured out.

[0115] 3. After the weighing pan maintains the dumping angle for a certain period of time, the control circuit board controls the motor in the metering push and flip device to start rotating in the reverse direction. The weighing pan rotates back to the horizontal state and then moves back horizontally. After touching the limit switch, the motor stops rotating and the weighing pan is reset.

[0116] 4. When the metering push and flip device is reset, the control circuit board controls the motor in the rear door device to rotate inward, driving 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 to a certain angle, the sensor dial touches the rear door reset sensor, and the motor stops rotating. The rear door device is in the closed state.

[0117] 5. Wait for the next medicine dispensing.

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 line winder continues to rotate for a certain period of time to release more weight line, leaving the extra weight line hanging in the air so that it does not 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 node on the clockwork line and needs to be set in advance. (7) After the weight falls onto the scale plate of the metering push-turn device, the positioning node fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning node is larger than the small hole of the spring sheet, the mainspring continues to be retracted, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor to stop rotating; (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.
