[0017] The control method of the metering pushing and flipping device includes the following steps:

[0018] (1), Before the weighing operation of the weighing scale, the superior system controls the electronic scale control circuit board to zero the metering data;

[0019] (2) The weighing pan receives the medicinal herbal pieces output by the medicine taking device;

[0020] (3) The electronic scale sensor under the weighing pan real-time detects the weight of the medicinal herbal pieces in the weighing pan, and uploads the weight data to the superior system through the electronic scale control circuit board in real time;

[0021] (4) After the weight of the medicinal herbal pieces 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;

[0022] (5) When the metering pushing and flipping device receives the dumping command issued by the superior system, the motor of the metering pushing and flipping device drives the lead screw 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 weighing pan rotating plate, and the slider drives the weighing pan rotating plate to move linearly, thereby driving the weighing pan to move linearly; when the weighing pan moves to a certain position, the gear on the weighing pan rotating plate meshes with the rack, so that the weighing pan has a flipping movement on the basis of the linear movement; when the weighing pan moves linearly to the specified position, the limit lever touches the limit touch switch and then stops moving. At this time, the flipping movement of the weighing pan just flips the weighing pan to a certain angle, so that the medicinal herbal pieces in the weighing pan pour out, completing the medicine discharging; after the weighing pan stays in the dumping state for a few seconds, the motor rotates in the reverse direction, driving the weighing pan to first rotate and fall back to the horizontal state, and make a linear movement back to the initial starting point. The motor stops operating after the limit lever touches the reset touch switch;

[0023] (6) The weighing pan resets, the weighing of the weighing pan is cleared, and it waits for the next operation.

[0024] Compared with the prior art, the present invention has the following technical features and advantages:

[0025] 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.

[0026] 2. 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 unit medicine cabinet. Through the pluggable terminal in the wire groove, the one-key connection mode of the unit medicine cabinet for power-on communication can be realized.

[0027] 3. Adaptability: By adopting different hoppers, upper discharging medicine taking devices and stirring devices, it can adapt to the changes in the shape and bulk density of the medicinal herbal pieces, and complete the work of taking out different medicinal herbal pieces.

[0028] 4. Modularity: All kinds of devices in the unit medicine cabinet, such as the upper and lower material medicine-taking device, conversion cutting device, stirring device, metering pushing and flipping device, 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. In particular, the clamping strip of the upper and lower material medicine-taking device is matched with the card slot on the hopper, and the positioning and fixing of the two components are realized by using locking screws and locking holes, achieving the rapid installation, disassembly and positioning of the upper and lower material medicine-taking device.

[0029] 5. Good sealing performance: Taking the unit medicine cabinet as an independent space, all joints are sealed. The opening and closing interfaces of devices that are often opened, such as the medicine adding door, cabinet front door, rear door device, upper cover plate, etc., are sealed with rubber strips, making the unit medicine cabinet box body a closed space and having a good effect of preventing mosquitoes and flies.

[0030] 6. Precise medicine dispensing: The upper and lower material medicine-taking device adopts a special composite conveyor belt. Through the careful design of the width of the composite conveyor belt, the height and width dimensions of the baffle, and the upward slope of the upper and lower material medicine-taking device, and then through the action of the limited spring piece and the inner material cover, the excess medicinal herb slices are blocked in the hopper, ensuring that only a certain amount of medicinal herb slices can be taken out during the medicine-taking process of the upper and lower material medicine-taking device. Finally, the sheet-shaped medicinal herb slices are cut into small pieces by the conversion cutting device to achieve the purpose of accurate medicine dispensing.

[0031] 7. Fast medicine dispensing speed: A large-torque brushless DC motor is selected. When the composite conveyor belt rotates one circle, a large amount of medicinal herb slices can be taken out.

[0032] 8. Eliminate the phenomenon of material bridge: Through the operation of the stirring device in the hopper, prevent the medicinal herb slices in the hopper from forming a material bridge during the sliding process, so that the medicinal herb slices can smoothly slide down with the medicine-taking of the upper and lower material medicine-taking device.

[0033] 9. Have self-cleaning ability: Inside the upper and lower material medicine-taking device, a cleaning scraper is designed, 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 medicine residue in the medicine residue bag regularly.

[0034] 10. Good heat dissipation performance: Ventilation mesh holes are arranged at the position of the control board corresponding to the cabinet front door to ensure the heat dissipation of the control board; an air intake mesh hole with a dust-proof net is arranged at the rear end of the cabinet box, and a heat dissipation exhaust mesh hole is arranged 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, thus achieving the purpose of heat dissipation.

[0035] 11. The operating status 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 status of the unit medicine cabinet can be judged.

[0036] 12. 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, and it is convenient to replace other types of hoppers without replacing the cabinet box.

[0037] 13. Prevent medicine spilling during medicine adding: Side baffles for the feeding door are provided on both sides of the medicine adding door to prevent the medicinal herbs from accidentally falling outside the hopper during the medicine adding process; the side baffle of the medicine adding door is inserted into the baffle box of the medicine adding door, and a sealing brush strip is provided inside the baffle box of the medicine adding door to prevent the medicinal herbs from accidentally falling into the side baffle box.

[0038] 14. Prevent pollution: The control board is covered with a control board box, isolating the connection between the control board and the internal space of the cabinet box, and avoiding the pollution of the control board by the medicine dust in the cabinet box; for some unit medicine cabinets, more medicine dust may be generated during the process of taking the corresponding medicinal herbs, which may pollute 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 discharging 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 discharging area with larger medicine dust will not pollute the heat dissipation area, and the medicine discharging area is regularly cleaned during use.

[0039] 15. 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.

[0040] 16. Regularly calibrate the metering error: A metering calibration device is installed above the metering pushing and flipping device corresponding in the unit medicine cabinet. The upper-level system can regularly control the metering calibration device through the unit medicine cabinet control board 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.

[0093] Working process:

[0094] Dosing:

[0095] 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.

[0096] 2. The user loads the medicinal pieces into the hopper.

[0097] 3. The user manually closes the dosing door and the dosing is completed.

[0098] Get medicine:

[0099] After the control panel receives the medicine picking instruction sent by the superior system, the control panel controls the stirring device to start stirring, controls the metering and pushing and flipping device to start metering, controls the position of the ordinary discharge port at the conversion and cutting device to correspond to the position of the upper discharge and medicine picking device, and controls the upper discharge and medicine picking device to start operating. The motor in the upper discharge and medicine picking device drives the composite conveyor belt to rotate. The baffle on the composite conveyor belt takes out the medicinal slices, passes through the limit spring piece and the inner material cover, and under the action of the limit spring piece and the inner material cover, the excess medicinal slices are blocked in the hopper, ensuring that the baffle only takes out one piece or one grain of medicinal slice. Finally, it falls into the weighing pan in the metering and pushing and flipping device through the ordinary discharge port of the conversion and cutting device. When the weight of the medicinal slices in the weighing pan in the medicine tray is greater than or equal to the rough medicine picking metering set value, the control panel controls the upper discharge and medicine picking device to stop operating. The control panel controls the conversion and cutting device to switch the cutting discharge port to the position corresponding to the upper discharge and medicine picking device, controls the upper discharge and medicine picking device to start jogging to pick up medicine, and the medicinal slices enter the cutting discharge port. When the sensor senses that there are medicinal slices in the cutting discharge port, the control panel controls the upper discharge and medicine picking device to stop jogging to pick up medicine, controls the cutting motor to start operating, and the cutting blade and the cutting tool holder cut the medicinal slices into small pieces. The cut small pieces of medicinal slices fall into the weighing pan in the metering and pushing and flipping device. Until the required weight is reached, the metering and pushing device stops metering, the upper discharge and medicine picking device stops operating, the stirring device stops stirring, and the control panel controls the conversion and cutting device to be at the ordinary discharge port.

[0100] Medicine discharging:

[0101] 1. After the control system receives the medicine discharging instruction sent by the superior system, the control panel controls the motor in the rear door device to rotate outward, drives the connecting rod and the sensor dial to rotate outward, the connecting rod jacks 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, the motor stops rotating, and the rear door device remains in the open state.

[0102] 2. While the control panel controls the rear door device to operate, it controls the metering and pushing and flipping device to operate. The motor in the metering and pushing and flipping 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, enabling the weighing pan to have a flipping motion on the basis of horizontal movement and start pouring out the medicinal slices. Until 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.

[0103] 3. After the weighing pan maintains the pouring angle for a certain period of time, the control panel controls the motor in the metering and pushing and flipping device to start rotating in the reverse direction. The weighing pan rotates back to the horizontal state, then moves horizontally back and touches the limit switch, and the motor stops rotating, and the weighing pan resets.

[0104] 4. After the metering and pushing turnover device is reset, the control 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.

[0105] 5. Wait for the next medicine dispensing.

[0106] The side baffle of the medicine adding door is inserted into the side baffle box in the closed state. There is a sealing brush strip at the upper opening of the side baffle box of the medicine adding door to prevent the medicinal herb slices from accidentally falling into the side baffle box.

[0107] The motor in the upper discharge and medicine taking device drives the composite conveyor belt to rotate. The baffle on the composite conveyor belt takes out the medicinal herb slices, passes through the medicine limit spring piece and the inner material cover. Under the action of the medicine limit spring piece and the inner material cover, the excess medicinal herb slices are blocked in the hopper, ensuring that the baffle only takes out one medicinal herb slice, thus meeting the requirement of accurate metering.

[0108] Rear door automatic closing device: When the control system controls the rear door to open, the motor drives the dial to rotate. The dial drives the connecting rod to push outward. The connecting rod pushes the upper sealing plate of the rear door to open, and the lower sealing plate of the rear door follows the upper sealing plate of the rear door to open. After opening a certain angle, the right end extension arm of the dial touches the rear door limit switch, and the motor stops rotating. At this time, the rear door is in the open state. When the control system controls the rear door to close, the motor drives the dial to rotate back. The dial drives the connecting rod to pull inward. The connecting rod pushes the upper sealing plate of the rear door to close, and the lower sealing plate of the rear door follows the upper sealing plate of the rear door to close. The dial touches the rear door reset switch, and the motor stops rotating.

[0109] Heat dissipation holes are provided at the position of the control board corresponding to the front door of the cabinet to ensure the heat dissipation of the control 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 middle motor, and then discharges the hot air through the exhaust fan, thus achieving the purpose of heat dissipation.

[0110] The control board is covered with a control board box, isolating the connection between the control board and the internal space of the cabinet box, avoiding the pollution of the control board by the medicine dust in the cabinet box; during the process of taking medicine for the medicinal herb slices 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 net 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 pollute the heat dissipation area, and the medicine dispensing area is regularly cleaned during use.

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.
