[0032] A medicine residue bag is mounted on the rear opening of the medicine residue box.

[0033] Compared with the prior art, the present invention has the following technical features and advantages:

[0034] 1. Independence: A unit medicine cabinet is an independent individual. As long as it is connected to the external power supply and communication network, it can independently complete the tasks of adding, taking and dispensing medicine.

[0035] 2. One-key connection mode: The wire trough on the cabinet is a reserved channel for the unit medicine cabinet to connect the power cord and communication line outside the cabinet. The one-key connection mode of the unit medicine cabinet power supply and communication can be realized through the plug-in terminal in the wire trough.

[0036] 3. Adaptability: By adopting different hoppers, upper discharging and medicine taking devices and stirring devices, the shape and bulk density of medicinal materials can be adapted to complete the work of taking out medicine from different medicinal materials.

[0037] 4. Modularity: All kinds of devices in the unit medicine cabinet, such as the upper discharging and dispensing device, stirring device, metering push flip, metering calibration device, rear door device, dosing door, cabinet front door, etc., are modularly designed and have relatively independent functions. If a device fails, it can be replaced separately, thereby realizing rapid replacement and maintenance. In particular, the card strip of the upper discharging and dispensing 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 is adopted, which realizes the rapid assembly and disassembly and positioning of the upper discharging and dispensing device.

[0038] 5. Good sealing: The unit medicine cabinet is an independent space, and all joints are sealed. The opening and closing interfaces of 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 an enclosed space with good mosquito-proof effect.

[0039] 6. Accurate medicine dispensing: By increasing the spacing between the baffles on the composite conveyor belt, the spacing between the medicinal materials on the composite conveyor belt is increased, and the time for the two medicinal materials to pass through the infrared counter is increased, ensuring that the infrared counting can achieve accurate statistics of the number of medicinal materials.

[0040] 7. Fast medicine dispensing speed: Choose a large torque brushless DC motor, and the composite conveyor belt can produce a large amount of medicinal materials by rotating one circle.

[0041] 8. Eliminate the material bridge phenomenon: Through the operation of the stirring device in the hopper, the medicinal pieces in the hopper are prevented from forming a material bridge during the sliding process, so that the medicinal pieces can slide smoothly along with the medicine taken by the upper discharging device.

[0042] 9. Self-cleaning capability: A cleaning scraper is designed inside the upper discharging and drug taking device, which can clean the drug residue and drug dust attached to the inside of the composite tape through the residue opening into the drug residue cover, and finally accumulate in the drug residue bag. You only need to clean the drug residue in the drug residue bag regularly.

[0043] 10. Good heat dissipation: A breathable mesh is set at the position of the control panel on the front door of the cabinet to ensure the heat dissipation of the control panel; an air intake mesh with a dustproof net is set at the rear end of the cabinet, and a heat dissipation exhaust mesh is set at the front end of the cabinet. An exhaust fan is installed on the mesh. When the exhaust fan is running, fresh air enters from the air intake mesh at the rear end of the cabinet, taking away the heat generated by the middle motor, and then the hot air is discharged through the exhaust fan, thereby achieving the purpose of heat dissipation.

[0044] 11. The operating status of the unit medicine cabinet is obvious: the operating status of the unit medicine cabinet can be judged by observing the color of the medicine shortage indicator light and the fault indicator light on the front door of the cabinet.

[0045] 12. Advantages of split-unit medicine cabinet: Split-unit medicine cabinet can separate the hopper from the cabinet box. The hopper positioning pin on the hopper and the hopper positioning slot on the cabinet box are assembled together for positioning, and then fastened to the hopper through the fixing holes on the cabinet box. Therefore, the hopper and the cabinet box are easy to assemble and disassemble, and it is convenient to replace other types of hoppers without changing the cabinet box.

[0046] 13. Prevent medicine from being scattered during dosing: Side baffles are set on the left and right sides of the dosing door to prevent the medicinal pieces from accidentally falling out of the hopper during the dosing process; the side baffles of the dosing door are inserted into the baffle box of the dosing door, and a sealing brush strip is set in the side baffle box of the dosing door to prevent the medicinal pieces from accidentally falling into the side baffle box.

[0047] 14. Prevent pollution: The control panel is covered with a control panel box, which isolates the control panel from the internal space of the cabinet and prevents the drug dust in the cabinet from contaminating the control panel; some unit medicine cabinets may generate more drug dust during the process of taking the medicinal pieces, which will pollute the inside of the unit medicine cabinet. To prevent this kind of drug dust pollution, a dust-proof isolation plate (or dust-proof isolation mesh) can be set to divide the inside of the cabinet into two areas, the upper one is the heat dissipation area, and the lower one is the drug output area, so as to reduce the space contaminated by drug dust. The two areas are isolated from each other and do not affect each other. The drug dust generated in the drug output area with larger drug dust will not pollute the heat dissipation area. The drug output area should be cleaned regularly during use.

[0048] 15. Manual unlocking: The electric locks of the cabinet front door and the dosing door are designed with manual mechanical unlocking parts. In the event of failure of the electric lock, the cabinet front door and the dosing door can be opened manually. BRIEF DESCRIPTION OF THE DRAWINGS

[0117] (2) The weighing pan receives the medicinal material pieces output by the medicine dispensing device;

[0118] (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;

[0119] (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;

[0120] (5) The metering push flipping device receives the dumping command issued by the superior system, and the motor of the metering push flipping device drives the screw to rotate, pushes the T-flange nut to move, and the T-flange nut drives the slider to move linearly on the slide rail; the slider is connected to the scale pan turntable, and the slider drives the scale pan turntable to move linearly, thereby driving the scale pan to move linearly; when the scale pan moves to a certain position, the gear on the scale pan turntable meshes with the rack, so that the scale pan has a flipping movement on the basis of linear motion; when the scale pan moves linearly to the specified position, the limit lever touches the limit touch switch and stops moving. At this time, the flipping movement of the scale pan just flips the scale pan to a certain angle, so that the medicinal materials in the scale pan are dumped out, and the medicine is discharged; after the scale pan remains in the dumped state for a few seconds, the motor rotates in the opposite direction, driving the scale pan to rotate back to the horizontal state first, and then make a linear motion back to the initial starting point, and the motor stops after the limit lever touches the reset touch switch;

[0121] (6) The scale pan is reset and the weight is cleared to zero, waiting for the next operation.

[0122] Working process of this unit cabinet:

[0123] Dosing:

[0124] 1. The control panel receives the unlocking command of the dosing door from the upper system, and the control panel controls the electric lock of the dosing door to be powered on and unlocked. The dosing door automatically pops up and opens under the action of the spring sheet and remains open.

[0125] 2. The user loads the medicinal pieces into the hopper.

[0126] 3. The user manually closes the dosing door and the dosing is completed.

[0127] Get medicine:

[0128] After the control board receives the medicine picking instruction from the superior system, the control board controls the stirring device to start stirring, the control board controls the infrared counter to start counting, and the control board controls the upper discharging and medicine taking device to start action. The baffle on the composite conveyor belt drives the medicinal slices, passes through the medicine limiting spring, and blocks the excess slices outside the inner medicine cover, ensuring that only one baffle brings out one medicinal slice, so that the medicinal slices can be discharged one by one in an orderly manner. When the circular medicinal slices pass through the infrared counter on the rear cover, the control board counts through the infrared counter, and the medicinal slices finally fall into the weighing pan. At this time, the weighing pan does not measure, but only serves to receive, push, and flip the medicine. When the medicinal slices in the medicine tray reach the required number, the upper discharging and medicine taking device stops moving and the stirring device stops stirring.

[0129] Dispensing medicine:

[0130] 1. After the control system receives the medicine dispensing instruction from the superior system, the control panel 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.

[0131] 2. The control panel controls the action of the push-turn device while controlling the action of the rear door device. The motor in the push-turn device starts to rotate, pushing the scale plate toward the rear door. After moving horizontally for a certain distance, the gear and rack on the scale plate engage, so that the scale plate can flip on the basis of horizontal movement and start to dump the medicinal materials. After the scale plate flips to a certain angle and touches the limit switch, the motor stops rotating and the scale plate stops flipping. At this time, the medicinal materials can be completely dumped out.

[0132] 3. After the scale pan maintains the tilting angle for a certain period of time, the control panel controls the motor in the push-turn device to start rotating in the opposite direction, the scale pan rotates back to a horizontal state, and then moves back horizontally. After touching the limit switch, the motor stops rotating and the scale pan resets.

[0133] 4. When the push-turn device is reset, the control panel 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 and lower sealing plates 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, the motor stops rotating, and the rear door device is in a closed state.

[0134] 5. Wait for the next dose of medicine.

A control method using the flipping device according to any one of claims 1 to 8, The following steps are involved: (1) Before weighing, the upper system controls the electronic scale control circuit board to reset the measurement data to zero; (2) The weighing pan receives the medicinal material pieces output by the medicine dispensing device; (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; (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; (5) The metering push flipping device receives the dumping command issued by the superior system, and the motor of the metering push flipping device drives the screw to rotate, pushes the T-flange nut to move, and the T-flange nut drives the slider to move linearly on the slide rail; the slider is connected to the scale pan turntable, and the slider drives the scale pan turntable to move linearly, thereby driving the scale pan to move linearly; when the scale pan moves to a certain position, the gear on the scale pan turntable meshes with the rack, so that the scale pan has a flipping movement on the basis of linear motion; when the scale pan moves linearly to the specified position, the limit lever touches the limit touch switch and stops moving. At this time, the flipping movement of the scale pan just flips the scale pan to a certain angle, so that the medicinal materials in the scale pan are dumped out, and the medicine is discharged; after the scale pan remains in the dumped state for a few seconds, the motor rotates in the opposite direction, driving the scale pan to rotate back to the horizontal state first, and then make a linear motion back to the initial starting point, and the motor stops after the limit lever touches the reset touch switch; (6) The scale pan is reset and the weight is cleared to zero, waiting for the next operation.

10. A method for controlling a control panel of a unit medicine cabinet according to any one of claims 1 to 8, It is characterized in that The following steps are involved: Dosing:

1. The control panel receives the unlocking command of the dosing door from the upper system, and the control panel controls the electric lock of the dosing door to be powered on and unlocked. The dosing door automatically pops up and opens under the action of the spring sheet, and remains in the open state; 2. The user loads the medicinal pieces into the hopper; 3. The user manually closes the dosing door and the dosing is completed; Get medicine: After the control panel receives the medicine picking instruction from the superior system, the control panel controls the stirring device to start stirring, controls the infrared counter to start counting, and controls the upper discharging and medicine taking device to start action; the baffle on the composite conveyor belt drives the medicinal slices, passes through the medicine limiting spring, and blocks the excess slices outside the inner medicine cover, ensuring that only one baffle takes out one medicinal slice, so that the medicinal slices are discharged one by one in an orderly manner; when the round medicinal slices pass through the infrared counter on the rear cover, the control panel counts through the infrared counter, and the medicinal slices finally fall into the weighing pan; at this time, the weighing pan does not measure, but only serves to receive, push, and flip the medicine. After the medicinal slices in the medicine tray reach the required number, the upper discharging and medicine taking device stops moving, and the stirring device stops stirring; Dispensing medicine:

1. After the control system receives the medicine dispensing instruction from the superior system, the control panel 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; 2. The control panel controls the action of the push-turn device while controlling the action of the rear door device. The motor in the push-turn device starts to rotate, pushing the scale plate to move toward the rear door. After a certain distance of horizontal movement, the gear on the scale plate engages with the rack, so that the scale plate can also flip on the basis of horizontal movement, and starts to dump the medicinal materials. After the scale plate flips to a certain angle and touches the limit switch, the motor stops rotating and the scale plate stops flipping. At this time, the medicinal materials can be completely dumped out; 3. After the scale pan keeps the tilting angle for a certain period of time, the control panel controls the motor in the push-turn device to start rotating in the opposite direction, the scale pan rotates back to a horizontal state, and then moves back horizontally. After touching the limit switch, the motor stops rotating and the scale pan resets; 4. When the push-turn device is reset, the control panel 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 and lower sealing plates 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, the motor stops rotating, and the rear door device is in a closed state.

5. Wait for the next dose of medicine.
