Description

Technical Field

[0001] The present invention relates to an intelligent traditional Chinese medicine cabinet, in particular to a spiral-pushing and discharging bulk traditional Chinese medicine slice unit cabinet. Background Art

[0002] As a treasure of traditional Chinese medicine, traditional Chinese medicine has played a huge role in the health of the Chinese people and the prosperity of the nation over its thousands of years of history. However, there are still areas in the traditional Chinese medicine industry that need improvement.

[0003] The traditional dispensing method of traditional 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 in the traditional 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.

[0004] Technical personnel in the field of traditional Chinese medicine have proposed some solutions for the automation of traditional Chinese medicine dispensing and dispensing. First, the "automatic traditional 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 outlet pipe and a temporary medicine outlet device. Weigh each traditional Chinese medicine independently and use negative pressure to suck and concentrate the medicine to achieve centralized dispensing. Second, the "fully automatic intelligent traditional Chinese medicine dispensing machine for cut pieces" (CN104828445): There are at least two columns of dispensing units on the frame. The dispensing unit consists of a medicine storage box, a linear motion module, a flipping material taking hopper, a linear feeding hopper, etc. It is controlled by a mechanical automation program and has the characteristics of accurate measurement and fast dispensing speed.

[0005] None of the above technical solutions can complete all operations such as adding medicine, taking medicine, and discharging medicine in a centralized, automated and intelligent manner within a single unit cabinet. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following technical features and advantages:

[0020] 1. Independence: One unit medicine cabinet is an independent individual, and as long as the external power supply and communication network are connected, it can independently complete the tasks of adding medicine, taking medicine and discharging medicine.

[0021] 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 plug-in wiring terminals in the wire groove, the one-key connection mode of power-on communication for the unit medicine cabinet can be realized.

[0022] 3. Adaptability: By adopting different hoppers, spiral pushing and discharging medicine taking devices and stirring devices, it can adapt to the changes in the shape and bulk density of the medicinal herb slices and complete the work of taking out different medicinal herb slices.

[0023] 4. Modularity: Various devices within the unit medicine cabinet, such as the spiral push discharging and dispensing device, stirring device, metering push and flip device, metering calibration device, rear door device, dosing door, and cabinet front door, all adopt a modular design and have relatively independent functions. If a device malfunctions, it can be replaced separately, thus achieving rapid replacement and maintenance. In particular, the locking strip of the spiral push discharging and dispensing device matches the slot on the hopper, and the design method of fixing the two components in place with a locking screw and locking hole realizes the rapid assembly, disassembly, and positioning of the spiral push discharging and dispensing device.

[0024] 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 dosing door, cabinet front door, rear door device, and upper cover are sealed with rubber strips, making the unit medicine cabinet box an enclosed space with good anti-mosquito effect.

[0025] 6. Accurate medicine discharging: The spiral push discharging and medicine taking device adopts trapezoidal spiral grooves of different sizes, cooperates with the inching discharging method and the weighing measurement of the metering scale, which can achieve precise control of the discharging of various Chinese herbal medicines.

[0026] 7. Fast medicine discharging speed: The cross-sectional size design of the trapezoidal spiral groove is matched with the bulk density ratio of the medicinal materials. Every time the screw rotates a certain angle, a certain weight of medicinal materials will be pushed out. With the continuous and uninterrupted rotation of the screw, the spiral pushing discharging and medicine taking device will continuously take out the medicinal materials from the hopper, and the medicine discharging efficiency is relatively high.

[0027] 8. Eliminate the material bridge phenomenon: Through the operation of the stirring device in the hopper, the medicinal materials in the hopper are prevented from forming a material bridge during the sliding process, so that the medicinal materials can slide smoothly along with the medicine taking device.

[0028] 9. Easy to maintain: The mechanical parts of the spiral push discharging and medicine taking device are reasonably designed and simple in structure. They are easy to disassemble and replace, and convenient for maintenance.

[0029] 10. Scalability: Each mechanical component of the spiral push discharging and medicine taking device can be expanded and upgraded according to production and use requirements, and has good scalability.

[0030] 11. 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.

[0031] 12. 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.

[0032] 13. Small interference and accurate measurement: High-precision electronic scale sensors are selected, with stable output sensitivity, small hysteresis error, and little influence from temperature and vibration. The electronic scale sensor and the metering module are tightly arranged together with short wiring. The output signal wire of the metering module uses a shielded wire, so the external interference is small.

[0033] 14. 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 through the fixing holes on the cabinet box. Thus, the hopper and the cabinet box are easy to disassemble and assemble, which is convenient for replacing other types of hoppers without replacing the cabinet box.

[0034] 15. Prevent medicine scattering during medicine addition: Side baffles for the feeding door are set on both sides of the medicine addition door to prevent the medicinal herbs 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 set in the baffle box of the medicine addition door side baffle to prevent the medicinal herbs from accidentally falling into the side baffle box.

[0035] 16. 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, avoiding the dust of the medicine in the cabinet box from polluting the control board; for some unit medicine cabinets, more medicine dust may be generated during the process of taking medicine for 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 internal part of the cabinet box into two areas. The upper part is the heat dissipation area, and the lower part is the medicine output 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 output area with larger medicine dust will not pollute the heat dissipation area, and the medicine output area is cleaned regularly during use.

[0036] 17. Manual unlocking available: The electric control locks of the front door and the medicine addition door of the cabinet are both designed with manual mechanical unlocking parts. In the case of the failure of the electric control lock, the front door and the medicine addition door can be opened manually.

[0037] 18. 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 superior 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.

[0082] A method for controlling a metering and overturning device of a unit medicine cabinet for discharging bulk Chinese herbal medicine pieces with a spiral pusher comprises the following steps:

[0083] (1) Before the weighing operation, the upper system controls the electronic scale control circuit board to reset the measurement data to zero;

[0084] (2) The weighing pan receives the medicinal pieces output by the medicine dispensing device;

[0085] (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;

[0086] (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;

[0087] (5) The metering push flipping device receives the dumping command from the superior system, and the motor of the metering push flipping device drives the screw to rotate, pushing the T-type flange nut to move, and the T-type flange nut drives the slider to move linearly on the slide rail; the slider is connected to the scale plate, and the slider drives the scale plate 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 engages with the rack, so that the scale plate has a flipping motion on the basis of 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, so that the medicinal materials in the scale plate are dumped out, completing the medicine dispensing; after the scale plate remains in the dumping state for a few seconds, the motor rotates in the opposite direction, driving the scale plate to rotate back to the horizontal state first, and then make a linear motion back to the original starting point. After the limit lever touches the reset touch switch, the motor stops;

[0088] (6) The scale pan is reset and the measurement is cleared to zero, waiting for the next operation.

[0089] A method for measuring and calibrating a measuring and calibrating device of a unit medicine cabinet for discharging bulk Chinese herbal medicine pieces with a spiral pusher comprises the following steps:

[0090] (1) The control system issues a "measurement correction" command;

[0091] (2) The unit medicine cabinet control panel controls the metering push flip device to clear the weighing pan;

[0092] (3) The unit medicine cabinet control panel controls the operation of the metering calibration device motor, driving the winding rod of the mainspring wire and the weight wire winding device to rotate;

[0093] (4) The weight line reel releases the weight line and gently puts the weight down. At the same time, the weight releases the reset touch switch, and the unit medicine cabinet control panel detects that the weight has moved;

[0094] (5) As the weights move, the winding rod reels in the winding wire, pulling the winding wire out of the winding disc, turning it through the pulley, passing through the small hole at one end of the spring sheet, and winding it into the wire groove in the winding rod;

[0095] (6) The weight continues to drop until it falls into the scale pan of the metering push-turn device. The weight is no longer subjected to any tension. 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.

[0096] (7) After the weight falls onto the scale plate of the metering push-turn device, the positioning section fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning section is larger than the small hole of the spring sheet, the mainspring is further wound up, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control panel detects that the weight has reached the predetermined position and controls the motor to stop rotating.

[0097] (8) When the weight of the specified weight of the metering calibration device falls into the scale pan of the metering push-turning device, the meter of the metering push-turning 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 meter of the metering push-turning device is judged to be qualified. If the comparison error exceeds the specified error range, the meter of the metering push-turning device is unqualified. The unit medicine cabinet control board alarms the superior system, prompting that the meter in the metering push-turning device needs to be replaced;

[0098] (9) After the control system controls the metering and pushing device to complete automatic metering and calibration, it controls the motor to rotate in the reverse direction. The weight wire winder retracts the weight wire to lift the weight, and the spring wire winding rod releases the spring wire. Under the tension of the spring wire, the spring wire is wound into the spring disc. The positioning section returns with the spring wire, and the spring piece rebounds to release the weight in place to touch the switch. The control system detects that the weight starts to return.

[0099] (10) The weight continues to rise and enters the weight reset fixing seat. The weight is fixed, pressing the dial of the weight reset touch switch. The system detects that the weight reaches the initial fixed position and controls the motor to stop rotating.

[0100] (11) The metering and calibration are completed.

[0101] A control method for a spiral pushing and discharging bulk Chinese herbal medicine piece unit medicine cabinet, including the following steps:

[0102] Adding medicine:

[0103] (1) When the control board receives the unlocking instruction for the medicine adding door sent by the superior system, 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.

[0104] (2) The user loads the medicinal herb pieces into the hopper.

[0105] (3) The user manually closes the medicine adding door, and the medicine adding is completed.

[0106] Retrieving medicine:

[0107] After the control board receives the medicine picking instruction sent by the superior system, the control board controls the stirring device to start stirring, controls the metering and pushing device to start metering, and controls the spiral pushing and discharging medicine picking device to start operating; the motor in the spiral pushing and discharging medicine picking device drives the trapezoidal spiral rod to rotate, and the trapezoidal spiral groove on the trapezoidal spiral rod pushes the medicinal herb pieces to move in the spiral cylinder until they are pushed to the discharge port; the rotation speed of the spiral pushing and discharging mechanism is adjustable to meet the requirements of different discharge rates and precise metering of different pieces; the medicinal herb pieces fall into the weighing pan in the metering and pushing flipping device through the discharge cover until the weight of the medicinal herb pieces in the medicine tray in the weighing pan is greater than or equal to the rough medicine picking metering set value, the spiral pushing and discharging medicine picking device starts to pick medicine by jogging. Until the required weight is reached, the metering and pushing device stops metering, the spiral pushing and discharging medicine picking device stops operating, and the stirring device stops stirring.

[0108] Discharging medicine:

[0109] (1)After the control system receives the medicine delivery instruction issued 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 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, and the motor stops rotating, and the rear door device remains in the open state;

[0110] (2)While the control board controls the action of the rear door device, it controls the action 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, enabling the weighing pan to have a flipping motion on the basis of horizontal movement and start to pour 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;

[0111] (3)After the weighing pan maintains the dumping angle for a certain period of time, the control 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, then moves horizontally back and touches the limit switch, and the motor stops rotating, and the weighing pan is reset;

[0112] (4)When the metering push and flip device is reset, 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; After completing the above series of medicine delivery actions, the metering calibration device will automatically calibrate the weighing scale to ensure that every subsequent weighing is accurate;

[0113] (5)Wait for the next medicine delivery.

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 slices 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 metering and pushing device to start metering, and controls the spiral pushing discharging and medicine taking device to start action; the motor in the spiral pushing discharging and medicine taking device drives the trapezoidal spiral rod to rotate, and the trapezoidal spiral groove on the trapezoidal spiral rod pushes the medicinal material slices to move in the spiral cylinder until they are pushed to the discharge port; the speed of the spiral pushing discharging mechanism is adjustable to adapt to the discharge rate and precise metering requirements of different medicinal materials; the medicinal material slices pass through the discharge cover and fall into the weighing pan in the metering and pushing flipping device until the weight of the medicinal material slices in the medicine pan on the weighing pan is greater than or equal to the rough medicine metering set value, the spiral pushing discharging and medicine taking device starts to jog medicine until the required weight is reached, the metering and pushing device stops metering, the spiral pushing 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 upper 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 cover plate of the rear door and drives the lower cover 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 movement of the rear door device while controlling the movement of the metering, pushing and flipping device. The motor in the metering, pushing and flipping device starts to rotate, pushing the scale plate 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 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. (3) After the scale pan maintains the tilting angle for a certain period of time, the control panel controls the motor in the metering push-turning device to start rotating in the reverse 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 metering 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 the closed state. After completing the above series of medicine dispensing actions, the metering calibration device will automatically calibrate the metering scale to ensure that each subsequent weighing is accurate. (5) Wait for the next dose of medicine.
