[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The medicine bag dispensing machine is compact in design: the body of the medicine bag dispensing machine is compressed as much as possible in design, freeing up more space for the medicine bag box to load more medicine bags. The general height of the medicine bag dispensing machine is 10cm, and it can dispensing medicine from continuous medicine bags with an average thickness of 2cm. If the average thickness of the medicine bag is greater than 2cm, the overall height of the medicine bag dispensing machine will be increased.
[0018] 2. The unit medicine cabinet is installed with guide positioning: there is a strip-shaped slot at the bottom of the medicine bag box, and a corresponding card strip is set on the rack. When the medicine bag box is installed on the rack, it can play a good role in positioning, guiding and fixing.
[0019] 3. The conveyor is stable and fast: The conveyor consists of a conveyor motor, a gear set, and two sets of upper and lower conveyor belts. When conveying continuous medicine bags, the upper and lower conveyor belts move synchronously, pulling the continuous medicine bags from both the upper and lower sides at the same time, effectively avoiding the continuous medicine bags from wrinkling, rolling, and curling during the pulling process, and can pull the continuous medicine bags more smoothly and quickly. The table plate of the medicine bag box outlet and the baffles on both sides are inward-facing trumpet-shaped. When the continuous medicine bags are pulled out by the conveyor of the medicine bag machine, the continuous medicine bags can be well prevented from being offset and twisted.
[0020] 4. The internal status of the medicine bag box can be observed: There is a sliding observation window on the cover of the medicine bag box, and the status of the medicine bags in the medicine bag box can be observed at any time during operation.
[0021] 5. 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.
[0022] 6. The shearing device is exquisite, efficient and fast: The shearing device has a compact structure and occupies little space, which greatly reduces the overall size of the medicine bag dispensing machine. Only one motor is used to achieve the compaction and shearing of continuous medicine bags. The cutting blade is made of high-speed steel, which has high hardness, good toughness, sharpness, and wear resistance. The cut of the medicine bag is smooth. There is a food-grade silicone strip at the bottom of the medicine bag pressure strip. When the pressure strip presses the continuous medicine bag, the silicone strip can well prevent the continuous medicine bag from sliding during the shearing process, making the cut of the medicine bag smooth.
[0023] 7. Four functions of the socket lock box: The socket lock box is compact and has the functions of power supply, communication, fixed locking and interchangeable medicine bag boxes. That is: one-touch insertion can connect power and communication; a power-off type electromagnet can be used to lock and fix the medicine bag box; the socket lock box is designed to a uniform specification and installed in a uniform position on the rack, so it is also applicable to different models of medicine bag dispensers.
[0024] 8. Prevent drug dust pollution: Picking up medicines by bagging medicinal materials can perfectly avoid drug contamination during the process of taking out medicines.
[0025] 9. Modular design, easy to replace and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The medicine bag taking machine 20 is composed of a conveying device 37 and a shearing device 36 installed in a machine case;
[0043] The structure of the conveying device is as follows: the driving gear on the conveying motor 42 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 50, 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 part of the chassis to form a front upper roller 44 and a front lower roller 46 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 part of the chassis, and the upper conveyor belt 45 mounted on the front upper roller and the rear upper roller is tilted downward, and the lower conveyor belt 47 mounted 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 convey continuous medicine bags;
[0044] The shearing device 36 arranged at the rear of the conveying device has the following structure: a first cross-beam 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 discharging plate 7 with a shearing notch thereon is fixed horizontally on the frame, two vertical shafts respectively provided with linear bearings are fixed between the left and right sides of the bottom surface of the medicine discharging plate and the frame, a knife seat 5 is fixed between the two linear bearings, and a knife seat notch 5a is provided on the knife seat for inserting the rotating plate lever 3 and lifting it upward or forcing it downward, and a blade 5b is installed for shearing continuous medicine bags, two second linear bearings 11 are respectively fixed on the left and right sides of the frame, 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 notch 6a for inserting the rotating plate lever 3 and forcing it downward or for lifting it upward; a second cross-beam sensor 13 and a second limit switch 16 are installed on the bottom surface of the medicine discharging plate;
[0045] The rotating plate 2 is connected to the shaft of the shearing motor 1, the rotating plate lever 3 is eccentrically fixed on the rotating plate, two first linear bearings 10 are fixed on the frame, two horizontal shafts are respectively mounted on the two first linear bearings 10, two pressure rod buckles 4 are respectively fixed on 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;
[0046] When the pressure rod is pressed to the bottom, the rotating plate contacts the second vertical surface 4c of the pressure rod buckle, and the pressure rod buckle is pushed to the innermost position. At this time, the lever enters the knife seat slot, and the medicine bag cutting position is also pressed by the pressure plate. At the same time, as the rotating plate continues to rotate, the lever will leave the pressure rod slot; at the bottom, the pressure rod buckle has not yet clamped the pressure rod, and when the lever is at a very small clockwise angle at the bottom, the pressure rod buckle will clamp the pressure rod. During this period, the pressure rod will rise a short distance; the rotating plate lever has a deflection The raised cylinder in the center will continue to press the pressure rod when it rotates at this small angle, keeping the pressure rod at the lowest point, that is, maintaining the pressure on the shearing edge of the medicine bag, to ensure successful shearing; as the rotating plate rotates, the pressure rod buckle will clamp the pressure rod, and the raised cylinder will leave the pressure rod to ensure successful shearing afterwards; the lever enters the knife seat slot, driving the knife seat to move upward, so that the blade shears the medicine bag. After the medicine bag is sheared, the knife seat also moves to the position of touching the second limit switch. When the knife seat touches the second limit switch, the unit medicine cabinet control board controls the shearing motor to rotate counterclockwise, and the rotating plate pushes the pressure rod buckle backward by contacting the inclined surface of the pressure rod buckle. When the rotating plate exits the knife seat slot, it immediately drives the pressure rod to move upward, the pressure plate also moves upward, and the cut medicine bag falls under the action of gravity; when the pressure plate moves up until it touches the first limit switch above, the motor stops, completing a shearing work, and the shearing device returns to its initial state.
[0047] See also Fig.37 When the driving gear rotates counterclockwise, the upper and lower conveyor belts on the first and fourth driven gear shafts are synchronized (same speed) and the upper conveyor belt rotates counterclockwise, while the lower conveyor belt rotates clockwise, clamping the continuous medicine bags and pushing them backwards. Fig.26, a medicine dispensing door opening and closing mechanism 35 is also provided at the rear part of the chassis of the medicine dispensing machine: the medicine dispensing door motor 21 is installed on the rear side vertical plate of the rear cover 14, the connecting member 22 has a first baffle 23 and the inner end of the second baffle 24 is fixed on the medicine dispensing door motor shaft, and the outer end of the connecting member is fixed on the medicine dispensing door 26, and the third matching sensor 25 is installed on the rear side vertical plate of the rear cover located on the rotation path of the first baffle and the second baffle. When the control circuit board 48 receives the medicine picking instruction sent by the superior system, the medicine dispensing door motor is controlled to rotate in the reverse direction to open the medicine dispensing door. When the medicine dispensing door is fully opened and the first baffle is inserted into the third matching sensor, the medicine dispensing door motor stops rotating and the medicine dispensing door remains in a fully open state. When the control circuit board receives the stop medicine picking instruction sent by the superior system, the medicine dispensing door motor is controlled to rotate forward to close the medicine dispensing door. When the medicine dispensing door is fully closed and the second baffle is inserted into the third matching sensor, the medicine dispensing motor stops rotating and the medicine dispensing door remains in a closed state.
[0048] See also Fig.30 , Fig.33 , Fig.38 A lock box connecting plate 38 is provided below the medicine outlet door on the rear side vertical plate of the medicine bag box, and a power supply communication interface and two positioning columns are provided on the lock box connecting plate;
[0049] It also has a lock box 19: a de-energized electromagnet 56 is mounted on a magnet seat 58, the magnet seat is mounted on the bottom plate of the lock box, two positioning cylinders 53 used for inserting and fixing two positioning columns on the lock box connecting plate, and a connector 54 used for cooperating with the power supply and communication interface on the lock box connecting plate are arranged on the inner surface of the inclined top plate of the lock box.
[0050] See also Fig.29 , Fig.31 , Fig.32 , Fig.33 Two card strips are arranged at the bottom of the chassis of the medicine bag dispensing machine, and the chassis is connected to two card slots on the rear base 31 of the medicine bag box through the two card strips.
[0051] A gear cover plate 39 is provided at the front of the gear set 50; a control board box 41 is provided on the inner surface of the top plate above the front upper roller, and a control circuit board 48 is installed in the control board box; two front flip covers 49 are installed on the top of the left and right side vertical plates of the medicine bag dispensing machine chassis; a cover plate 18 is provided on the top of the medicine bag box, and an observation window 28 is provided on the cover plate, and a medicine discharging baffle 29 and a medicine discharging bottom plate 30 of a continuous medicine bag in an inwardly contracted trumpet-shaped shape are provided at the rear of the medicine bag box, and a handle 32 is installed on the front side vertical plate of the medicine bag box.
[0052] Fig.11 , Fig.12 It is shown that when the shearing instruction is received, the rotating plate starts to rotate clockwise under the drive of the shearing motor, and at the same time drives the pressure rod to move downward. When the pressure rod moves downward, it will contact the first inclined surface of the pressure rod buckle, pushing the pressure rod buckle backward.
[0053] Fig.13 , Fig.14 , Fig.15 As shown, the rotating plate continues to rotate, and when the pressure rod moves from the first inclined surface of the pressure rod buckle to the first vertical surface of the pressure rod buckle, the rotating plate contacts the second vertical surface of the pressure rod buckle at the same time. As the rotation continues, the pressure rod is separated from the pressure rod buckle. When the rotating plate rotates to the bottom, the rotating plate lever just enters the knife seat slot. At this time, the pressure rod buckle is pushed to the innermost position and has not yet locked the pressure rod. Under the action of the rotating plate lever, the knife seat and the pressure rod are at the bottom. Then, as the rotating plate continues to rotate, the contact surface between the rotating plate and the pressure rod buckle will move from the second vertical surface to the second inclined surface. During this short process, as the pressure plate presses tightly against the shearing opening on the medicine outlet plate and the rotating plate rotates, the pressure rod will also rise a short distance. However, as the lever has an eccentrically raised cylindrical section, the pressure rod will continue to be pressed at a stable height during this short process (i.e., 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, thereby reducing the pressure at the shearing opening and causing subsequent shearing failure.) 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.
[0054] Fig.16 , Fig.17 It shows that the rotating plate continues to rotate, the lever exits from the pressure lever slot, and the rotating plate lever enters the knife seat slot, thereby driving the knife seat to move upward. When the rotating plate contacts the second inclined surface of the pressure lever buckle, as the rotating plate rotates, the pressure lever buckle moves forward under the action of the spring, and the pressure lever is stuck (before being stuck, the pressure lever is always at the lowest point due to the eccentric cylindrical section on the rotating plate lever).
[0055] Fig.18 , Fig.19 It shows that: 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.
[0056] Fig. 20 , Fig.21 It shows that: the rotating plate rotates counterclockwise, and when the rotating plate touches the second inclined surface of the pressure rod buckle, as the rotating plate continues to rotate, the pressure rod buckle will be pushed backward by the rotating plate.
[0057] Fig. 22 , Fig.23 It shows that after the rotating plate rotates counterclockwise to the bottom, the rotating plate contacts the second vertical surface of the pressure rod buckle, thereby releasing the pressure rod, and the rotating plate lever enters the pressure rod slot. As the rotating plate continues to rotate counterclockwise, the rotating plate lever will exit the tool holder slot, and continued rotation will drive the pressure rod to rise.
[0058] Fig.24 , Fig.25It shows that the rotating plate drives the pressure rod to move upward. After the pressure rod rises for a while, the rotating plate will not contact the pressure rod buckle, and the pressure rod will resist 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 first limit switch, the motor stops rotating and a shearing is completed). Return to the initial state.
[0059] Charge installation:
[0060] Open the cover of the medicine bag box, place a certain number of continuous medicine bags neatly into the medicine bag box, take out one end of the continuous medicine bag, open the front cover of the medicine bag dispensing machine, put one end of the continuous medicine bag into the conveying device of the medicine bag dispensing machine, and let the upper and lower conveyor belts of the medicine bag dispensing machine clamp the medicine bag (Note: the end of the medicine bag cannot exceed the conveying device to avoid blocking the shooting counting device of the shearing device.), cover the front cover of the medicine bag dispensing machine, assemble the medicine bag dispensing machine and the medicine bag box, cover the cover of the medicine bag box, install the assembled continuous medicine bag dispensing unit medicine cabinet to the designated position of the frame, push the continuous medicine bag dispensing unit medicine cabinet to the designated position so that it can be successfully docked with the connector of the socket lock box, and now the medicine loading and installation work is completed.
[0061] Working process:
[0062] 1. Picking medicine: When the unit medicine cabinet control board receives the medicine picking instruction sent by the superior system, the unit medicine cabinet control board driver controls the medicine dispensing door motor to rotate in the opposite direction to open the medicine dispensing door. When the medicine dispensing door is fully opened and the baffle of the motor connector is inserted into the through-shooting sensor, the medicine dispensing door motor stops rotating and the medicine dispensing door remains fully open. At the same time, the unit medicine cabinet control board driver controls the conveyor belt motor to start working, and the conveyor belt motor drives the gear set to drive the upper and lower conveyor belts to move synchronously, and the medicine bags are sent to the shearing device evenly and smoothly. The through-shooting sensor on the shearing device counts the medicine bags passing through the shearing port. When the count reaches the number of medicine bags in the medicine picking instruction, the conveyor device stops working and waits for the shearing device to cut the medicine bags and take out the medicine.
[0063] 2. Cutting out medicine: When the unit medicine cabinet control panel receives the medicine dispensing instruction sent by the superior system, the unit medicine cabinet control panel driver controls the shearing device motor to start 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 drives the pressure plate downward at the same time, gradually tightening the incision position of the medicine bag. When the rotating plate lever presses the pressure rod to contact the first inclined surface of the pressure rod buckle, as the pressure rod slides downward on the first inclined surface of the pressure rod buckle, the pressure rod buckle is pushed to move backward. When the pressure rod is pressed to the first vertical surface of the pressure rod buckle below the first inclined surface of the pressure rod buckle, the rotating plate just rotates to the second vertical surface of the pressure rod buckle. As the rotating plate lever rotates to the bottom, the pressure rod just moves down and disengages from the first vertical surface of the pressure rod buckle. The rotating plate rotates to the middle of the second vertical surface of the pressure rod buckle. At this time, the pressure rod buckle also retreats to the innermost position. When the turn plate lever presses the pressure bar to the bottom, the turn plate lever also enters the knife seat slot, but at this time, the pressure bar buckle is held by the turn plate and has not yet clamped the pressure bar. As the turn plate continues to rotate from the bottom, the turn plate enters the second pressure bar buckle inclined surface. At this time, the pressure bar buckle gradually extends to the top of the pressure bar under the thrust of the spring as the turn plate slides on the second pressure bar buckle inclined surface, clamping the pressure bar. In order to prevent the pressure bar from moving upward with the rotation of the turn plate lever, the section of the turn plate lever that presses the pressure bar is provided with a raised eccentric cylindrical section to ensure that the turn plate will continue to press the pressure bar at a stable height during the rotation and sliding of the second pressure bar buckle inclined surface, thereby ensuring that the pressure bar buckle can fully extend to the top of the pressure bar, press the pressure bar, and prevent the turn plate lever from leaving the pressure bar as the turn plate rotates and the pressure bar moves back, thereby maintaining a continuous and stable pressure on the medicine bag incision to ensure the success of the medicine bag shearing. Then, the rotating plate lever drives the knife holder to move upward, so that the blade cuts the medicine bag. After the medicine bag is cut, the knife holder also moves to the position of touching the limit switch. When the knife holder touches the limit switch, the unit medicine cabinet control panel controls the shearing device motor to rotate counterclockwise. The shearing device motor drives the rotating plate to rotate in the opposite direction, and the rotating plate lever drives the knife holder to move downward. When the knife holder returns to the bottom, the rotating plate lever exits the knife holder slot. When the rotating plate rotates counterclockwise to contact the second inclined surface of the pressure bar buckle, it starts to push the pressure bar buckle backward and away from the pressure bar, until the rotating plate rotates to the bottom and the rotating plate slides to the second vertical surface of the pressure bar buckle, the pressure bar buckle is completely pushed away from the pressure bar. When the rotating plate rotates to the bottom, the rotating plate lever enters the pressure bar slot. As the rotating plate continues to rotate counterclockwise, the rotating plate lever drives the pressure bar to move upward, and at the same time drives the pressure plate to move upward. When the pressure plate touches the upper limit switch, the motor stops working, completing a complete shearing movement. When the pressing plate moves upward, the compressed medicine bag is released, and the cut medicine bag falls into the medicine tray below by its own weight. At this point, one cutting and discharging of medicine is completed.
