Description

Technical Field

[0001] The invention relates to a lifting mechanism for an intelligent Chinese medicine cabinet, in particular to a lifting pressure plate mechanism attached to a hopper of the intelligent Chinese medicine cabinet and installed on the hopper for medicine adding operation. Background Art

[0002] As a treasure of Chinese medicine, traditional Chinese medicine has played a huge role in its history of thousands of years. However, the traditional Chinese medicine industry itself still has room for improvement and improvement in many aspects.

[0003] Traditional Chinese medicine (TCM) dispensing is typically done manually. This means that when a patient arrives at the pharmacy to pick up their medicine, the pharmacist manually retrieves, weighs, and prepares the medicine from a drawer in the traditional Chinese medicine cabinet according to the prescription. This manual dispensing method is inefficient, prone to errors, and time-consuming.

[0004] Technicians in the field of traditional Chinese medicine have proposed some solutions for the automation of Chinese medicine preparation and dispensing, such as the "fully automatic intelligent Chinese medicine dispensing machine for medicinal slices" (CN104828445A): the machine frame is equipped with at least two rows of dispensing units, which are composed of a medicine storage box, a linear motion module, a flip hopper, a linear feeding hopper, etc., and are controlled by a mechanical automation program, and also have the characteristics of accurate measurement and fast dispensing speed.

[0005] None of the above technical solutions can centrally and intelligently complete all operations such as adding, shaving, removing, and dispensing medicines within a single unit medicine cabinet. Furthermore, the shaving operation within a single unit medicine cabinet involves shearing and shaving equipment, and the feeding of these equipment requires a supporting lifting device for the medicinal material raw materials. Summary of the Invention

[0006] The present invention provides a lifting and pressing plate mechanism attached to a hopper, designed for use with a planing / shearing unit medicine cabinet. This mechanism provides a well-sealed hopper and prevents material bridging during lifting operations. This mechanism is suitable for use with the inventor's "Smart Pharmacy Intelligent Dispensing and Dispensing System for Chinese Herbal Pieces."

[0007] The object of the present invention is achieved as follows: a lifting and pressing plate mechanism attached to a hopper, the hopper is composed of a front plate, a rear plate, a left plate and a right plate, the unit medicine cabinet is composed of a cabinet box and a hopper assembly, the hopper assembly is composed of a hopper and an upper cover plate integrated into one, the rectangular upper cover plate is buckled on the upper end surface of the cabinet box top opening, the hopper extends into the inner cavity of the cabinet box, a dosing door with side baffles on the left and right sides is hinged at the dosing port on the front of the upper cover plate, and a baffle box for inserting the side baffles of the dosing door when closing the dosing door is fixed on the left and right inner walls of the dosing port of the upper cover plate; the cabinet front door is arranged in front of the cabinet box via a door hinge, and the rear door for dispensing medicine is arranged on the rear panel of the cabinet box;

[0008] The rear plate of the hopper is an oblique plate member, and the upper roller and the lower roller are respectively installed on the outer walls of the upper and lower strip grooves of the rear plate of the hopper, and the annular steel belt used to seal the strip groove is hung on the upper roller and the lower roller; the hinge pressure plate assembly structure is as follows: a plurality of pressure rods are fixed on a horizontal bar along the longitudinal direction and at equal intervals, and a hinge pressure plate is installed at the front of each pressure rod via a torsion spring, and the counterweight block is transversely fixed to the rear of all pressure rods, and when no external force is applied, the hinge pressure plates of all pressure rods form an integral pressure plate adjacent to each other under the action of the torsion spring. A fixing seat for being fixed to the lifting mechanism via bolts is fixed on the longitudinal fixed shaft fixed in the middle of the horizontal bar, and a lowering limit switch and a lifting limit switch are installed on the fixing seat. A clamping mechanism for grabbing the grab plate is vertically arranged on the horizontal plate of the fixing seat: the upper and lower ends of the central axis of the bayonet fixing shaft respectively have a round table and a disc, and an inverted round table symmetrical to the shape of the round table, that is, a movable bayonet shaft, is movably sleeved on the central axis;

[0009] The longitudinal fixed axis of the hinge pressure plate assembly extends into the inner cavity of the hopper through a through-hole of the annular steel belt and a strip groove of the hopper, and only the fixing seat and the clamping mechanism of the hinge pressure plate assembly are located outside the hopper;

[0010] A hinged folding frame is installed on the upper part of the rear wall of the hopper cavity;

[0011] The lifting mechanism structure used to grab the hinge pressure plate assembly is as follows: the slide rail is fixed on the outer wall of the hopper rear plate parallel to the hopper strip groove, the slider is slidably arranged on the slide rail, the fixed seat of the hinge pressure plate assembly is fixedly connected to the slider, the screw rod is installed on the outer wall of the hopper rear plate through the upper bearing seat and the lower bearing seat parallel to the slide rail, the outer end of the screw rod extending from the lower bearing seat is equipped with a driven gear, the driving gear installed on the reduction motor shaft installed on the lower bearing seat is meshed with the driven gear, the nut is screwed on the screw rod, the grabbing plate is fixed on the nut, and a plurality of grabbing plate nails of the set spring are respectively arranged in the openings on the side wall of the grabbing plate, the spring cover is sealed on the opening, and the tightening screw is screwed on the grabbing plate nail and The cam is pressed onto the spring cover. When the reduction motor drives the grabbing plate to move downward, the round table of the clamping mechanism overcomes the spring force and causes the grabbing plate nail to extend outward, thereby causing the round table to move upward and enter the upper chamber of the grabbing plate. At the same time, the grabbing plate touches the lifting limit switch to stop the reduction motor from rotating. The grabbing plate nail returns to its original shape under the action of the spring force, causing the grabbing plate nail to be clamped under the round table, thereby realizing the grabbing action of the grabbing plate. After completing the grabbing action of the grabbing plate, under the drive of the reduction motor, when the grabbing plate continues to move downward, the inverted round table located in the lower chamber of the grabbing plate moves upward to squeeze the grabbing plate nail into the upper chamber of the grabbing plate, and finally causes the entire clamping mechanism to disengage from the upper chamber of the grabbing plate, thereby completing the release action of the grabbing plate.

[0012] The structure of the hinge retracting frame 806 is as follows: a plurality of groups of bayonet-type parallel plates are fixedly connected to the strips arranged on the inner wall of the rear plate of the hopper, which are used to cooperate with each hinge pressure plate 803 in the hinge pressure plate assembly. When the hinge pressure plate assembly moves upward, each hinge pressure plate is gradually retracted under the blocking action of the corresponding group of bayonet-type parallel plates and finally reaches the top of the hinge retracting frame.

[0013] Another object of the present invention is to provide a control method for the lifting plate mechanism attached to the hopper.

[0014] Another object of the present invention is achieved in this way:

[0015] A control method for a lifting plate mechanism attached to a hopper includes the following steps:

[0016] Working process:

[0017] Dosing:

[0018] 1. The control panel receives the instruction from the upper system to unlock the dosing door.

[0019] 2. The control panel driver controls the reduction motor in the lifting mechanism to rotate, which drives the screw to rotate through the gear. The screw pushes the grabbing plate fixed on the screw nut to move downward. When the grabbing plate moves downward and passes through the round table, it touches the lifting limit switch. The control panel driver controls the reduction motor to stop rotating, and the grabbing plate stops moving downward. At this time, the grabbing plate nail pops out under the action of the grabbing plate spring, jamming the grabbing plate fixing tower cap, thus completing the grabbing action of the grabbing plate.

[0020] 3. When the grabbing plate completes the grabbing action, the control panel driver controls the reduction motor in the lifting mechanism to immediately start reverse rotation, the grabbing plate moves upward, and at the same time drives the pressing plate mechanism to move upward together, and drives the sealing steel belt to rotate in the opposite direction to ensure the sealing of the hopper;

[0021] 4. When the pressing plate mechanism is lifted to the top of the hopper, the hinge pressing plate in the pressing plate mechanism enters the hinge retracting frame, and the hinge pressing plate is retracted. At this time, the grabbing plate touches the limit switch of the lifting mechanism, and the control panel driver controls the reduction motor to stop, and the lifting mechanism and the pressing plate mechanism stop rising;

[0022] 5. The control panel driver 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.

[0023] 6. The user puts the medicinal slices into the hopper;

[0024] 7. The user manually closes the dosing door;

[0025] 8. The reduction motor of the lifting mechanism rotates, the grabbing plate moves downward, and the pressing plate mechanism moves downward under the action of its own weight and the grabbing plate. The hinge pressing plate exits the hinge retracting frame and is unfolded into a 180° flat plate under the action of the torsion spring. As the grabbing plate and the pressing plate mechanism continue to move downward, the hinge pressing plate contacts the top of the medicinal material slices in the hopper until the full weight of the pressing plate mechanism presses the medicinal material slices. At this time, the pressing plate mechanism will not move downward;

[0026] After the pressure plate mechanism stops moving, the lifting mechanism continues to move downward, and the grab plate moves downward with the lifting mechanism through the grab plate movable tower cap, that is, the inverted round table 708. After the grab plate passes through the grab plate movable tower cap, it touches the lowering limit switch, and the reduction motor starts to rotate in the opposite direction. The lifting mechanism starts to move upward, and the grab plate moves upward with the lifting mechanism through the grab plate movable tower cap and the grab plate fixed tower cap, so that the lifting mechanism grab plate is separated from the pressure plate mechanism. At this point, the release action of the grab plate is completed; the lifting mechanism continues to move upward, and the grab plate touches the lifting mechanism limit switch. The control board driver controls the reduction motor to stop, and the lifting mechanism stops rising; the lifting mechanism waits for the next grabbing task;

[0027] 9. The dosing work is completed.

[0028] Compared with the prior art, the present invention has the following technical features and advantages:

[0029] 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.

[0030] 2. Eliminate the phenomenon of material bridge: Under the action of its own weight and the counterweight block, the pressing plate mechanism compacts the fluffy medicinal slices, so that the medicinal slices in the hopper slide down as the medicinal slices are taken out, thereby avoiding the phenomenon of empty bridges in the medicinal slice materials.

[0031] 3. The airtightness of the hopper: When the pressing plate mechanism moves up and down, the sealing steel belt moves up and down with the pressing plate mechanism, and the steel belt pressing plate always presses the sealing steel belt, so that the sealing steel belt blocks the strip groove of the hopper to achieve the effect of sealing the hopper.

A fixed seat 801 is fixed to the longitudinal fixed shaft fixed in the middle of the horizontal bar, which is used to be fixedly connected to the lifting mechanism via bolts. The fixing seat is installed with a lowering limit switch 709 and a lifting limit switch 710.

[0055] The longitudinal fixed axis of the hinge pressure plate assembly 800 extends into the inner cavity of the hopper through a through hole 50d of the annular steel belt and the strip groove 5b of the hopper. Only the fixing seat 801 and the clamping mechanism of the hinge pressure plate assembly are located outside the hopper.

When the hinge pressure plate assembly moves upward, each hinge pressure plate is gradually retracted under the blocking action of the corresponding group of bayonet-type parallel plates and finally reaches the top of the hinge retracting frame.

[0060] Detailed process of grabbing the plate by the lifting mechanism

[0061] 1. The grab plate in the lifting device moves downward, and the bayonet fixing shaft passes through the hole below the grab plate (such as Figure 13 ).

[0062] 2. The grabbing plate continues to move downward, and the inclined surface on the bayonet fixed shaft squeezes and compresses the grabbing plate pin to move outward, and the grabbing plate pin compresses the spring (such as Figure 14 ).

[0063] 3. The grabber continues to move downward, and the upper inclined surface of the bayonet fixed shaft completely passes through the upper end spring of the grabber nail and the grabber nail to reset. At this time, the fixed shaft can be lifted by the grabber to achieve the grabbing effect. At this time, the lower edge of the grabber touches the lifting limit switch (such as Figure 15 Figure 18 ).

[0064] 4. The grabbing plate grabs the pressing plate mechanism and moves upward together (such as Figure 16 ).

[0065] Detailed process of lifting mechanism grabbing and lowering the plate:

[0066] 1. Initial state ( Figure 19 ).

[0067] 2. The grabbing plate continues to move downward, and the movable shaft of the bayonet squeezes the grabbing plate nail, causing the grabbing plate nail to move outward. The grabbing plate nail compresses the spring (such as Figure 20 ).

[0068] 3. The grabbing plate continues to move downwards. After the upper surface of the grabbing plate nail passes the upper surface of the bayonet movable shaft, the spring and the grabbing plate nail reset. At this time, the upper edge of the grabbing plate touches the lower limit switch. Figure 16 Figure 24 .

[0069] 4. The grabbing plate continues to move upward, and the grabbing plate nail lifts the bayonet movable shaft and moves upward. After the bayonet movable shaft and the bayonet fixed shaft are tightly attached, they continue to move upward, causing the grabbing plate nail to move outward, and the grabbing plate nail compresses the spring ( Figure 22 ).

[0070] 5. After the grabbing plate nail passes through the lower end surface of the bayonet fixed shaft, the grabbing plate will fall off from the bayonet shaft to achieve the effect of putting it down. Figure 22 Figure 17 .

[0071] Working process:

[0072] Dosing:

[0073] 1. The control panel receives the instruction from the upper system to unlock the dosing door.

[0074] 2. The control board driver controls the reduction motor in the lifting mechanism, which in turn rotates the lead screw through the gears. The lead screw pushes the grab plate, which is fixed to the lead screw nut, downward. When the grab plate moves downward and passes through the grab plate fixing cap (i.e., round platform 707), it hits the lifting limit switch. The control board driver controls the reduction motor to stop, and the grab plate stops moving downward. At this point, the grab plate pin is ejected by the grab plate spring, locking into the grab plate fixing cap, thus completing the grab plate's grabbing action.

[0075] 3. When the grabbing plate completes the grabbing action, the control panel driver controls the reduction motor in the lifting mechanism to immediately start reverse rotation, the grabbing plate moves upward, and at the same time drives the pressing plate mechanism to move upward together, and drives the sealing steel belt to rotate in the opposite direction to ensure the sealing of the hopper.

[0076] 4. When the pressing plate mechanism is lifted to the top of the hopper, the hinge pressing plate in the pressing plate mechanism enters the hinge retracting frame, and the hinge pressing plate is retracted. At this time, the grabbing plate touches the limit switch of the lifting mechanism, and the control panel driver controls the reduction motor to stop moving, and the lifting mechanism and the pressing plate mechanism stop rising.

[0077] 5. The control panel driver 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.

[0078] 6. The user puts the medicinal slices into the hopper.

[0079] 7. The user manually closes the dosing door.

[0080] 8. The reduction motor of the lifting mechanism rotates, the grabbing plate moves downward, and the pressing plate mechanism moves downward accordingly under the action of its own weight and the grabbing plate. The hinge pressing plate exits the hinge retracting frame, and the hinge pressing plate is expanded into a 180° flat plate under the action of the torsion spring. As the grabbing plate and the pressing plate mechanism continue to move downward, the hinge pressing plate contacts the top of the medicinal materials in the hopper until the full weight of the pressing plate mechanism presses the medicinal materials. At this time, the pressing plate mechanism will not move downward.

[0081] After the pressure plate mechanism stops moving, the lifting mechanism continues to move downward. The grab plate moves downward with the lifting mechanism, passing through the grab plate movable tower cap, i.e., the inverted circular table 708. After passing through the movable tower cap, the grab plate hits the lowering limit switch. The reduction motor begins to rotate in the opposite direction, and the lifting mechanism begins to move upward. The grab plate moves upward with the lifting mechanism, passing through the movable tower cap and the fixed tower cap, disengaging the lifting mechanism grab plate from the pressure plate mechanism, thus completing the grab plate release action. The lifting mechanism continues to move upward, and the grab plate hits the lifting mechanism limit switch. The control board driver controls the reduction motor to stop, and the lifting mechanism stops rising. The lifting mechanism then waits for the next grab task.

[0082] 9. The dosing work is completed.

When the grabbing plate completes the grabbing action, the control panel driver controls the reduction motor in the lifting mechanism to immediately start reverse rotation, the grabbing plate moves upward, and at the same time drives the pressing plate mechanism to move upward together, and drives the sealing steel belt to rotate in the opposite direction to ensure the sealing of the hopper; 4. When the pressing plate mechanism is lifted to the top of the hopper, the hinge pressing plate in the pressing plate mechanism enters the hinge retracting frame, and the hinge pressing plate is retracted. At this time, the grabbing plate touches the limit switch of the lifting mechanism, and the control panel driver controls the reduction motor to stop, and the lifting mechanism and the pressing plate mechanism stop rising; 5. The control panel driver 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.

6. The user puts the medicinal slices into the hopper; 7. The user manually closes the dosing door; 8. The reduction motor of the lifting mechanism rotates, the grabbing plate moves downward, and the pressing plate mechanism moves downward under the action of its own weight and the grabbing plate. The hinge pressing plate exits the hinge retracting frame and is unfolded into a 180° flat plate under the action of the torsion spring. As the grabbing plate and the pressing plate mechanism continue to move downward, the hinge pressing plate contacts the top of the medicinal material slices in the hopper until the full weight of the pressing plate mechanism presses the medicinal material slices. At this time, the pressing plate mechanism will not move downward; After the pressing plate mechanism stops moving, the lifting mechanism continues to move downward, and the grabbing plate moves downward along with the lifting mechanism, passes through the grabbing plate movable tower cap, i.e., the inverted circular table (708), and after the grabbing plate passes through the grabbing plate movable tower cap, it touches the lowering limit switch, the reduction motor starts to rotate in the opposite direction, and the lifting mechanism starts to move upward, and the grabbing plate moves upward along with the lifting mechanism, passes through the grabbing plate movable tower cap and the grabbing plate fixed tower cap, so that the lifting mechanism grabbing plate is separated from the pressing plate mechanism, and thus the release action of the grabbing plate is completed; the lifting mechanism continues to move upward, and the grabbing plate touches the lifting mechanism limit switch, and the control board driver controls the reduction motor to stop, and the lifting mechanism stops rising; the lifting mechanism waits for the next grabbing task; 9. The dosing work is completed.
