Description

Technical Field

[0001] The invention relates to a device for conveying, dividing and pre-sorting continuously bagged medicines, in particular to a medicine cabinet capable of pre-sorting a discharging unit of continuously bagged medicines. Background Art

[0002] In the prior art, there are pharmacies that dispense bagged medicines. Each bag of medicine has a fixed dosage. During the dispensing process, the purpose of dispensing medicines is achieved by simply conveying the continuous medicine bags that are connected in a long strip and manually cutting them.

[0003] A Chinese patent document discloses an automated pharmacy for bagged medicine (CN204433567): Long, strip-shaped bags of medicine are transported outward by a conveying device. At the medicine outlet, first and second rollers press the inside and outside of the broken edges of the bagged medicine, respectively, before the medicine is cut by a cutter in a cutting device. This patent is not suitable for automating the transport, cutting, counting, pre-sorting, and dispensing of continuously bagged medicine within the confined space of a unit medicine cabinet. Summary of the Invention

[0004] The purpose of the present invention is to provide a unit medicine cabinet for pre-sorting continuous bagged Chinese herbal medicine slices, which has a compact design, small space occupation, modularization, a smooth conveying device, and a fast and efficient shearing device.

[0005] The object of the present invention is achieved as follows: a unit medicine cabinet capable of pre-sorting continuous bagged Chinese herbal medicine slices is composed of one or more continuous bagged medicine taking-out machines installed on a machine frame;

[0006] The medicine taking-out machine is composed of a width-limiting guide device, a conveyor belt device and a shearing device which are sequentially installed in the machine box from front to back, and a medicine bag box which is installed on a frame below the medicine inlet of the machine box.

[0007] The structure of the conveyor belt device is as follows: the driving gear on the transmission motor shaft is adjacent to the left side plate of the chassis, the driving gear is meshed with the first, second, third and fourth driven gears in sequence to form a gear set, the second and third driven gears are the same, the first and fourth driven gears are the same, and the second and third driven gears are smaller than the first and fourth driven gears, the first and fourth driven gears are smaller than the driving gear, the fourth and first driven gear shafts are movably mounted on the left and right side plates of the front of the chassis to form a front upper roller and a front lower roller respectively, the rear upper roller and the rear lower roller corresponding to the front upper roller and the front lower roller are installed on the left and right side plates of the rear of the chassis, and the upper conveyor belt sleeved on the front upper roller and the rear upper roller is tilted downward, and the lower conveyor belt sleeved on the front lower roller and the rear lower roller is tilted upward, the rear end of the upper conveyor belt contacts the rear end of the lower conveyor belt and is used to clamp and transport continuous medicine bags;

[0008] The shearing device structure arranged at the rear of the conveyor device is as follows: a first matching sensor is installed on the inner surface of the rear cover bottom plate, a first limit switch is installed on the inner surface of the rear cover side plate, a medicine discharge plate with a shearing notch thereon is fixed horizontally on the frame, two vertical shafts with linear bearings respectively mounted on the left and right sides of the bottom surface of the medicine discharge plate and the frame are fixed, the knife holder is fixed between the two linear bearings, and the knife holder is provided with a knife holder notch for inserting a rotating plate lever and lifting it upward or forcing it down, and a blade for cutting continuous medicine bags is installed, two second linear bearings are fixed on the left and right sides of the frame respectively, the upper ends of the two vertical shafts installed in the two second linear bearings are fixed to the pressure plate, and the lower ends of the two vertical shafts are fixed to the pressure rod, and the pressure rod is provided with a pressure rod notch for inserting a rotating plate lever and forcing it down or for lifting it up; a second matching sensor and a second limit switch are installed on the bottom surface of the medicine discharge plate;

[0009] The rotating plate is connected to the shear motor shaft, the rotating plate lever is eccentrically fixed to the rotating plate, the two first linear bearings are fixed to the frame, the two horizontal shafts are respectively mounted on the two first linear bearings, the two pressure rod buckles are respectively fixed to the outer ends of the two horizontal shafts, and a spring is sleeved on the horizontal shaft between the pressure rod buckle and the first linear bearings;

[0010] In the initial state, the turn plate lever is in the pressure rod slot. When the unit medicine cabinet control panel receives the medicine dispensing instruction sent by the superior system, the unit medicine cabinet control panel controls the shearing device motor to start working. The shearing motor drives the turn plate to rotate clockwise. The turn plate lever presses the pressure rod downward, and drives the pressure plate downward at the same time. When the pressure rod contacts the first inclined surface of the pressure rod buckle and moves down to the first vertical surface of the pressure rod buckle, it starts to push the pressure rod buckle backward. When the lever presses the pressure rod to the bottom, the turn plate contacts the first inclined surface of the pressure rod buckle. On the second vertical surface, the pressure rod buckle is pushed to the innermost position, at this time the push rod enters the knife holder slot, and the medicine bag incision position is also pressed by the pressure plate. At the same time, as the rotating plate continues to rotate, the push rod will leave the pressure rod slot; at the bottom, the pressure rod buckle has not yet clamped the pressure rod. When the push rod is at the bottom and has a very small clockwise angle, the rotating plate enters the second inclined surface of the pressure rod buckle and slides from the inclined surface to the pressure rod. The pressure rod buckle will clamp the pressure rod. During this process, the pressure rod will rise a short distance The cam is pressed against the bottom edge of the knife block, and the ...

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

[0012] 1. The advantages of a separate box and machine design are significant: The continuous bagging medicine cabinet utilizes a design that combines a separate medicine removal machine and a medicine bag box. The medicine removal machine of the continuous bagging medicine cabinet is fixed to the frame and rarely moves after configuration. The medicine bag box of the continuous bagging medicine cabinet can be removed or installed at any time according to the consumption of medicine bags. The advantages of this design are: (1) The medicine removal machine is fixed to the frame, avoiding frequent movement of the medicine removal machine. Each time the medicine removal machine is removed, the power and communication line interfaces must be unplugged. Excessive movement can easily damage these interfaces and even damage the components or motor of the unit cabinet control board; (2) The medicine bag box does not contain any electronic components and only serves to hold medicine bags for loading onto the frame. Due to the frequent removal and installation of the medicine bag box, it is easily damaged. Therefore, the medicine bag box design is simple in structure, easy to replace, and low in cost. Users can have more spare ones for easy use or replacement; ⑶. A strip-shaped card slot is set at the bottom of the medicine bag box, and a raised card strip is set at the corresponding position on the rack. When the medicine bag box is installed on the rack, it can play a good positioning, guiding and fixing role.

[0013] 2. Compact design of the drug dispensing machine: The drug dispensing machine has a compact and rational design. The overall height is generally 10cm, which can meet the requirements of dispensing medicines from continuously packed bags with an average thickness of 2cm or less. If the average thickness of the medicine bags used by the user is greater than 2cm, the height of the drug dispensing machine can be increased to meet the requirements.

[0014] 3. The conveyor system of the medicine bag removal device is smooth and fast: The conveyor system consists of a conveyor motor, a gear set, and two sets of upper and lower conveyor belts. When conveying continuously packed medicine bags, the two sets of conveyor belts move synchronously, pulling the continuous bag from both the top and bottom surfaces simultaneously. This effectively prevents wrinkling, tumbling, and curling of the continuous bag during the pulling process, ensuring smoother and faster pulling of the continuous bag. The platform and side baffles of the medicine bag box outlet are both inward-facing, trumpet-shaped, effectively preventing the continuous bag from shifting and twisting when the continuous bag is pulled out by the conveyor system of the medicine bag removal device.

[0015] 4. Suitable for continuous bagging of various widths: A limited width guide device is installed at the front end of the drug dispensing machine. When continuous bagging of a certain size is loaded onto the machine, the baffle on the limited width guide device must be adjusted to the corresponding position. The limited width guide device is suitable for drug bag sizes of various widths. Its function is to prevent the continuous bagging device of the drug dispensing machine from swaying when removing the drug bag, which may cause the continuous bagging tape or metering to be inaccurate.

[0016] 5. The internal status of the medicine bag box can be observed: There is a transparent observation window on the medicine bag box, so you can observe the status of the medicine bags in the medicine bag box at any time.

[0017] 6. Accurate counting: The beam sensor of the shearing device counts the medicine bags passing through the shearing opening. This sensor has accurate counting, high position accuracy, stable data output, and strong anti-interference ability. It can ensure accurate counting of medicine bags and control the shearing position error of medicine bags within 2mm.

[0018] 7. Compact, efficient, and fast shearing mechanism: The shearing mechanism is compact and takes up little space, significantly reducing the overall size of the bag dispensing machine. A single motor is used to both compress and shear continuously packed bags. The cutting blades are made of high-speed steel, offering high hardness, toughness, sharpness, and wear resistance, resulting in smooth cuts. A food-grade silicone strip is affixed to the bottom of the bag holding strip. When the strip presses against the continuously packed bags, the silicone strip prevents the bags from slipping during the shearing process, ensuring a smooth cut.

[0019] 8. Real-time monitoring of the medicine cabinet's operating status: Two indicator lights are located on the medicine cabinet door: one indicates the cabinet's operating status, and the other indicates the remaining medicine bags in the medicine bag box. These two operating status indicators allow real-time monitoring of the cabinet's operating status and the remaining medicine bags.

[0020] 9. Prevent drug dust pollution: Picking up medicines by bagging medicinal pieces can perfectly avoid drug contamination problems during the process of taking out the medicines.

[0021] 10. Pre-picking and discharging medicines saves time: There is a pre-picking and conveying device behind the medicine removal machine. When a multi-dose prescription is discharged from the medicine bag, after the medicine bag of the first dose is sent out, the medicine bag of the second dose can be immediately cut and stored in the pre-picking and conveying device. There is no need to wait until the superior system issues the medicine discharging instruction for the second dose of the prescription, and then take out and cut the medicine bag of the second dose of the prescription. When the superior system issues the medicine discharging instruction for the second dose of the prescription, the medicine bag can be directly discharged, thereby effectively saving the time of taking out the medicine.

DETAILED DESCRIPTION

[0047] In the accompanying drawings, the clamping plate 18a, the tower spring 307, the cover plate 302, the upper conveyor belt 304, the front flip cover 308, the first inclined surface 4a (i.e., inclined surface 1), the first vertical surface 4b (i.e., vertical surface 1), the second vertical surface 4c (i.e., vertical surface 2), the second inclined surface 4d (i.e., inclined surface 2), the eccentrically raised cylinder 3a (on the turn plate lever), the clamping spring 303a, and the counter-rivet 313 (for fixing the rear upper roller).

[0048] Figures 39 to 42 A unit medicine cabinet for pre-sorting continuous bagged Chinese herbal medicine slices is shown, characterized in that it is composed of one or more continuous bagged medicine removal machines installed on a frame;

[0049] The medicine taking-out machine is composed of a width-limiting guide device 100, a conveyor device 300 and a shearing device 400 which are sequentially installed in the machine box from front to back, and a medicine bag box 17 which is installed on a frame below the medicine inlet of the machine box.

[0050] The structure of the conveyor belt device 300 is as follows: the driving gear on the shaft of the conveying motor 301 is adjacent to the left side plate of the chassis, and the driving gear sequentially meshes with the first, second, third and fourth driven gears to form a gear set 309, the second and third driven gears are the same, the first and fourth driven gears are the same, and the second and third driven gears are smaller than the first and fourth driven gears, and the first and fourth driven gears are smaller than the driving gear, the fourth and first driven gear shafts are movably mounted on the left and right side plates of the front of the chassis to form a front upper roller 303 and a front lower roller 306 respectively, and the rear upper roller and rear lower roller corresponding to the front upper roller and the front lower roller are installed on the left and right side plates of the rear of the chassis, and the upper conveyor belt 304 sleeved on the front upper roller and the rear upper roller is set to tilt downward, and the lower conveyor belt 305 sleeved on the front lower roller and the rear lower roller is set to tilt upward, and the rear end of the upper conveyor belt contacts the rear end of the lower conveyor belt to clamp and transport continuous medicine bags;

[0051] The shearing device 400 arranged at the rear of the conveyor device has the following structure: a first matching sensor 12 is installed on the inner surface of the bottom plate of the rear cover 14, a first limit switch 15 is installed on the inner surface of the side plate of the rear cover, a medicine discharge plate 7 with a shearing notch thereon is fixed horizontally on the frame, two vertical shafts with linear bearings respectively mounted on the left and right sides of the bottom surface of the medicine discharge plate and the frame are fixed, the knife seat 5 is fixed between the two linear bearings, and the knife seat is provided with a knife seat slot 5a for inserting the rotating plate lever 3 and lifting it upward or forcing it down, and a blade 5b for cutting continuous medicine bags is installed, two second linear bearings 11 are fixed on the left and right sides of the frame respectively, the upper ends of the two vertical shafts installed in the two second linear bearings 11 are fixed to the pressure plate 8, and the lower ends of the two vertical shafts are fixed to the pressure rod 6, and the pressure rod is provided with a pressure rod slot 6a for inserting the rotating plate lever 3 and forcing it down or for lifting it up; a second matching sensor 13 and a second limit switch 16 are installed on the bottom surface of the medicine discharge plate;

[0052] The rotating plate 2 is connected to the shaft of the shearing motor 1, the rotating plate lever 3 is eccentrically fixed to the rotating plate, the two first linear bearings 10 are fixed to the frame, the two horizontal shafts are respectively mounted on the two first linear bearings 10, the two pressure rod buckles 4 are respectively fixed to the outer ends of the two horizontal shafts, and a spring 9 is sleeved on the horizontal shaft between the pressure rod buckle and the first linear bearing;

[0053] In the initial state, the turn plate lever is in the pressure rod slot. When the unit medicine cabinet control panel receives the medicine dispensing instruction sent by the superior system, the unit medicine cabinet control panel controls the shearing device motor to start working. The shearing motor drives the turn plate to rotate clockwise. The turn plate lever presses the pressure rod downward, and at the same time drives the pressure plate downward. When the pressure rod contacts the first inclined surface 4a of the pressure rod buckle and moves down to the first vertical surface 4b of the pressure rod buckle, it starts to push the pressure rod buckle backward. When the lever presses the pressure rod to the bottom, the turn plate contacts the pressure rod buckle. On the second vertical surface 4c, the pressure rod buckle is pushed to the innermost position, at this time the push rod enters the knife holder slot, and the medicine bag incision position is also pressed by the pressure plate. At the same time, as the rotating plate continues to rotate, the push rod will leave the pressure rod slot; at the bottom, the pressure rod buckle has not yet clamped the pressure rod. When the push rod is at the bottom and has a very small clockwise angle, the rotating plate enters the second inclined surface 4d of the pressure rod buckle and slides from the inclined surface 4d to the pressure rod. The pressure rod buckle will clamp the pressure rod. During this process, the pressure rod will rise a little When the pressure plate moves up until it touches the first limit switch above, the motor stops, completing one shearing operation, and the shearing device returns to its initial state (see Figure 1). Figures 30 to 34 , Figures 26 to 29 The upper transmission belt and the lower transmission belt are both silicone transmission belts; an upper roller frame plate (45a) is provided above the upper transmission belt: it is composed of a top plate and left and right side vertical plates, and the left and right side vertical plates are respectively movably mounted on the front upper roller and the rear upper roller through two holes thereon;

[0054] In the initial state, if Figure 10 As shown, the rotating plate shift shaft is in the pressure rod slot.

[0055] Figure 11 Figure 12 : When the shearing command is received, the rotating plate begins to rotate clockwise driven by the shearing motor, and at the same time drives the pressure rod downward. When the pressure rod moves downward, it contacts the pressure rod buckle inclined surface 1, pushing the pressure rod buckle backward.

[0056] Figure 13 Figure 14 Figure 15As the turntable continues to rotate, the pressure rod moves from the pressure rod buckle inclined surface 1 to the pressure rod buckle vertical surface 1. The turntable also contacts the pressure rod buckle vertical surface 2. As the turntable continues to rotate, the pressure rod disengages from the pressure rod buckle. When the turntable rotates to the bottom, the turntable shift shaft just enters the tool holder slot. At this time, the pressure rod buckle is pushed to its innermost position and has not yet locked the pressure rod. Under the action of the turntable shift lever, the tool holder and pressure rod are at the bottom. Subsequently, as the turntable continues to rotate, the contact surface between the turntable and the pressure rod buckle will move from the vertical surface to the inclined surface 2. During this short process, as the pressure plate presses tightly against the shearing opening and the rotating plate rotates, the pressure rod will also rise a short distance. However, since the lever has an eccentric, raised cylindrical section, the pressure rod will continue to be pressed at a stable height during this short process (that is, the pressure plate continues to press tightly against the shearing opening of the medicine bag, preventing the pressure rod from rising slightly as the rotating plate rotates, reducing the pressure at the shearing opening and causing subsequent shearing to fail.) As the rotating plate rotates, this section of the cylinder will leave the pressure rod only after the pressure rod buckle locks the pressure rod.

[0057] Figure 16 Figure 17 The turn plate continues to rotate, and the shaft exits the notch in the pressure bar, driving the toolholder upward. When the turn plate contacts the inclined surface 2 of the pressure bar buckle, the turn plate rotates, and the pressure bar buckle, acting on the spring, moves forward, locking the pressure bar (before locking, the pressure bar is always at its lowest point due to the eccentric cylindrical section on the turn plate lever).

[0058] Figure 18 Figure 19 : The rotating plate drives the knife holder to rotate clockwise until the medicine bag is cut. At the same time, after the knife holder touches the limit switch, it immediately rotates counterclockwise, driving the knife holder to move downward.

[0059] Figure 20 Figure 21 : The turn plate rotates counterclockwise. When the turn plate touches the inclined surface 2 of the pressure rod buckle, as the turn plate continues to rotate, the pressure rod buckle will be pushed backward by the turn plate.

[0060] Figure 22 Figure 23 : After the turn plate rotates counterclockwise to the bottom, the turn plate contacts the vertical surface of the pressure rod buckle, thereby loosening the pressure rod, and the turn plate lever enters the pressure rod slot. As the turn plate continues to rotate counterclockwise, the turn plate lever will exit the tool holder slot, and continued rotation will drive the pressure rod to rise.

[0061] Figure 24 Figure 25 : The rotating plate drives the pressure rod to move upward. After the pressure rod rises a certain distance, the rotating plate will no longer contact the pressure rod buckle, and the pressure rod will press against the pressure rod buckle. As the rotating plate continues to rotate, the pressure rod is brought upward by the rotating plate (when the pressure plate touches the limit switch, the motor stops rotating, and one shear is completed). Return to the initial state.

[0062] See also Figures 30 to 34 The structure of the width limiting guide device 100 is as follows: the left and right ends of the arc-shaped guide plate 102 are respectively provided with a width limiting buckle 101 with the same structure that can move along the center line of the guide plate. The width limiting buckle of the left section is composed of: the buckle plate 101d is composed of an arc-shaped bottom plate and a vertical plate that are used to buckle on the guide plate. The shell 101a is composed of two horizontal side plates and a vertical top plate. The shell is fixed to the vertical plate of the buckle plate through the ear plates on the two horizontal side plates by screws. The upper buckle tongue 101e and the lower buckle tongue 101f are symmetrically arranged in the inner cavity of the shell, and the upper buckle tongue and the lower buckle tongue are movable. It is equipped with two shafts, each of which is fitted with a compression spring 101c. The pressing columns 101g and 101h fixed on the upper and lower buckle tongues extend from the holes of the two horizontal side plates of the shell respectively. When inward pressing force is applied to the two pressing columns, the upper and lower buckle tongues retract inward and can extend from the rectangular hole 101i of the arc-shaped bottom plate of the buckle plate and one of the multiple rectangular holes on the left section of the guide plate. After the pressing force is eliminated, the upper and lower buckle tongues return to their original positions and fix the left section width limiting buckle to a specific position on the guide plate; a mounting buckle 103 is fixed on the back of the guide plate. The width limiting guide device 100 is Figure 43 The two bar holes shown are fixed to the frame with screws.

[0063] See also Figure 36 Figure 37 The chassis also has a shearing device 400 and a pre-sorting conveying device 500 is installed at the rear: the motor base 502 is fixed to the rear of the chassis, the motor 501 is installed on the motor base, the driving gear 503 is installed on the motor shaft, the driven gear is engaged with the driving gear, the driving roller 505 is installed on the driven gear 504 shaft, the fixed shaft 510 is installed on the chassis, the inner ends of the two pad frames 508 are movably connected to the two outer ends of the fixed shaft, and the outer ends of the two pad frames 508 are movably connected to the driven roller 506, the conveyor belt 507 is sleeved on the active roller and the driven roller, and there are two openings on one edge of the conveyor belt with a spacing of half the length of the conveyor belt. The beam sensor 509 is installed on the chassis and the optical path between the transmitter and the receiver of the beam sensor can be covered by the above-mentioned edge of the conveyor belt.

[0064] The two support plates can rotate around fixed axes respectively so as to fit the conveyor belts on the driving roller and the driven roller.

[0065] The front door of the chassis is hinged on the chassis, and two indicator lights 19 are installed on the front door; a vertical plate type electromagnet seat 201 is fixedly connected to the front edge of the bottom plate 206 of the chassis, and the vertical plate has an opening for the mounting buckle 103 sleeve used as the width limiting guide device, and the power-off type electromagnet 202 is installed on the electromagnet seat. When the power is not supplied, the lock tongue 205 is adsorbed on the power-off type electromagnet, the cylinder and the torsion spring baffle 203 are fixed on the bottom plate 206, the torsion spring 204 is sleeved on the cylinder, and the two ends of the torsion spring are respectively against the torsion spring baffle and the lock tongue 205. When the power is supplied, the power-off type electromagnet loses its magnetism, and the lock tongue is separated from the electromagnet under the action of the torsion spring and is stuck in the opening on the side panel of the chassis, thereby fixing the width limiting guide device to the chassis. ( Figure 35 )

The removal machine consists of a unit medicine cabinet door, a control circuit board, a control circuit board box, a medicine bag removal device, a shearing device, and a pre-sorting and storage device. The unit medicine cabinet door is equipped with two indicator lights.

[0071] 2. Installation:

[0072] ⑴. Install the drug dispensing machine: Place the drug dispensing machine into the rack, hang the hanging shaft at the rear of the upper part of the drug dispensing machine on the hanging buckle of the rack, then support the drug dispensing machine with your hands and rotate it upward until the lock buckle at the upper front of the drug dispensing machine is locked on the spring lock tongue on the rack. This completes the installation of the drug dispensing machine on the rack. Then connect the power cord and communication line of the drug dispensing machine to ensure normal operation of the drug dispensing machine.

[0073] ⑵、Install the medicine bag box: Insert the medicine bag box filled with continuous bagging medicine bags and matched with the medicine removal machine into the rack through the raised guide rails on the rack chassis. When the medicine bag box is inserted into place, make sure that the upper edges of the side panels on both sides of the upper opening of the medicine bag box enter the card slots on both sides of the lower part of the medicine removal machine. After the medicine bag box is inserted into place, load the medicine bag onto the medicine removal machine to remove the medicine. Then, press the unit medicine cabinet door at the front end of the medicine removal machine so that the card slot on the unit medicine cabinet door is locked by the electromagnetic lock at the front of the medicine removal machine, thereby preventing the medicine bag box from exiting the rack.

Open the medicine cabinet door at the front of the medicine dispensing machine. Press the upper conveyor of the medicine dispensing machine upward. Then place the end of the continuously bagged medicine bag into the medicine dispensing machine. Lower the upper conveyor of the medicine dispensing machine so that the upper and lower conveyor belts of the medicine dispensing machine clamp the continuously bagged medicine bag. (Note: The end of the continuously bagged medicine bag must not extend beyond the conveyor to avoid blocking the shearing device's beam counting device.) Place the medicine bag following the end of the continuously bagged medicine bag into the width-limiting guide to ensure that the medicine bag does not shift during transportation. Continue pushing the medicine bag box into the machine frame until it is in place and close the front door of the medicine dispensing machine. This completes the medicine bag loading process.

[0076] 3. Take out the medicine:

[0077] 1. Medication Removal: When the unit medicine cabinet control board (hereinafter referred to as the unit medicine cabinet control board) receives a medicine pick-up instruction from the upper system, the unit medicine cabinet control board driver controls the medicine bag removal device in the medicine removal machine to begin medicine removal. The conveyor belt motor of the medicine bag removal device begins to operate, driving the gear train to synchronize the upper and lower conveyor belts, delivering the medicine bags evenly to the shearing device. Through the shearing device, the conveyor belt of the pre-sorting storage device also begins to operate at the same speed, ensuring that the continuous bagged medicine bags entering the pre-sorting storage device are spread more evenly in the pre-sorting storage device. As the continuous bagged medicine bags pass through the shearing device, the shearing device's cross-beam sensor counts the number of medicine bags passing through the shearing opening. When the count reaches the number of medicine bags required for the medicine pick-up instruction, the medicine bag removal device and the pre-sorting storage device stop operating, waiting for the shearing device in the medicine bag removal device to cut the medicine bags.

[0078] 2. Shearing: When the number of bags of medicine continuously packed into the shearing device reaches the number of medicine bags required by the medicine picking instruction, the medicine bag taking device and the pre-sorting medicine storage device stop working, and the unit medicine cabinet control board driver immediately controls the shearing device in the medicine removal machine to shear: the shearing device motor starts working, and the shearing device motor drives the rotating plate to rotate clockwise. The lever on the rotating plate presses the pressure rod downward, and at the same time drives the pressure plate downward, gradually tightening the position of the medicine bag cut. When the rotating plate lever presses the pressure rod to contact the pressure rod buckle inclined surface 1, as the pressure rod slides downward on the pressure rod buckle inclined surface 1, the pressure rod buckle moves backward. When the pressure rod presses to the pressure rod buckle vertical surface 1 below the pressure rod buckle inclined surface 1, the rotating plate just rotates to the pressure rod buckle vertical surface 2. As the rotating plate lever rotates to the bottom, the pressure rod just moves down and disengages from the pressure rod buckle vertical surface 1. The rotating plate rotates to the middle of the pressure rod buckle vertical surface 2. At this time, the pressure rod buckle also retreats to the innermost position. When the turn plate lever pushes the pressure bar to the bottom, the turn plate lever also enters the knife holder slot. However, at this time, the pressure bar buckle is held against the turn plate and has not yet locked the pressure bar. As the turn plate continues to rotate from the bottom, the turn plate enters the pressure bar buckle inclined surface 2. At this time, under the thrust of the spring, the pressure bar buckle gradually extends above the pressure bar as the turn plate slides on the pressure bar buckle inclined surface 2, locking the pressure bar. To prevent the pressure bar from moving upward as the turn plate lever rotates, the section of the turn plate lever that presses the pressure bar is provided with a raised eccentric cylindrical section. This ensures that the turn plate will continue to press the pressure bar at a stable height during the rotation and sliding of the pressure bar buckle inclined surface 2. This ensures that the pressure bar buckle can fully extend above the pressure bar, pressing the pressure bar, and prevent the turn plate lever from moving back after leaving the pressure bar as the turn plate rotates. This maintains the pressure plate's continuous and stable pressure on the medicine bag cut, ensuring successful medicine bag cutting. The turntable lever then drives the knife holder upward, allowing the blade to shear the bag. After the bag is sheared, the knife holder reaches the limit switch. When the knife holder hits the limit switch, the unit medicine cabinet control panel controls the shear mechanism motor to rotate counterclockwise. The shear mechanism motor drives the turntable in the opposite direction, and the turntable lever drives the knife holder downward. When the knife holder returns to the bottom, the turntable lever exits the knife holder slot. When the turntable rotates counterclockwise until it contacts the inclined surface 2 of the pressure bar buckle, it begins to push the pressure bar buckle backward and away from the pressure bar. This is achieved when the turntable bottoms out and slides onto the vertical surface 2 of the pressure bar buckle, completely pushing the pressure bar buckle away from the pressure bar. When the turntable bottoms out, the turntable lever enters the pressure bar slot. As the turntable continues to rotate counterclockwise, the lever drives the pressure bar upward, simultaneously driving the pressure plate upward. When the pressure plate hits the upper limit switch, the motor stops, completing a complete shearing operation. The cut medicine bags are temporarily kept in the pre-sorting conveyor, waiting for the medicine discharging instruction.

[0079] 3. Dispensing: When the unit medicine cabinet control panel receives the dispensing instruction from the upper system, the unit medicine cabinet control panel driver controls the pre-sorting conveyor to begin dispensing medicine. The pre-sorting conveyor motor starts to operate, driving the conveyor belt inside the pre-sorting conveyor toward the medicine outlet of the pre-sorting conveyor until the continuous bagged medicine bags remaining in the pre-sorting conveyor are sent out of the pre-sorting conveyor. This completes one dispensing operation and waits for the next dispensing.

[0080] On one side of the pre-sorting conveyor belt, there are two counting holes, spaced at a distance equal to half the belt's circumference. These holes are used by the pre-sorting conveyor's internal through-beam sensor to monitor the belt's rotation. When a counting hole passes the sensor, the sensor reads once, indicating the conveyor has completed half its rotation. If the sensor reads the counting holes twice in a row, the pre-sorting conveyor stops, indicating that the continuous bagged medicine bags remaining in the pre-sorting conveyor have been transported out of the conveyor.

[0081] 4. Pre-sorting and discharging medicines: When the unit medicine cabinet receives the task of picking up medicines for multiple prescriptions at the same time, the pre-sorting conveyor device will immediately pick up the medicine bag of the second prescription after transporting the medicine bag of the first prescription to the rack conveyor belt, and cut it and leave it in the pre-sorting conveyor device. When the medicine of the next prescription needs to be taken out, the medicine can be directly taken out, thereby greatly shortening the time for taking out the medicine for the next prescription.

[0082] 5. Wait for the next time to take out the medicine.

[0083] 6. Setting the maximum number of medicine bags that can be taken out: Due to the limited internal space of the pre-sorting conveyor device, in order to prevent medicine bags from falling out of the pre-sorting conveyor device and affecting the operation of other equipment, each unit medicine cabinet should set a maximum number of medicine bags that can be taken out based on the size of the medicine bags. When the number of medicine bags required for a dose of medicine is greater than this value, the control program of the unit medicine cabinet control panel must make a judgment and take out the medicine in two or more times to meet the medication requirements of this dose of medicine.
