Description

Technical Field

[0001] The present invention relates to the field of medicine distribution, and in particular to an intelligent track box-type logistics automatic retractable system and a use method thereof. Background Art

[0002] Currently, most hospitals still rely on online doctor prescriptions, which are then manually dispensed and delivered. This traditional manual dispensing and delivery method has many limitations: First, it is inefficient. Manual drug distribution and delivery is time-consuming, especially in large hospitals or during peak hours, which can lead to delayed drug delivery and affect treatment effectiveness. Second, the error rate is high. Human factors can easily lead to dispensing errors, such as choosing the wrong drug or incorrect dosage. These errors can have serious impacts on patients' health. Third, there is the risk of infection. Frequent interpersonal contact increases the risk of cross-infection, especially during epidemics. Fourth, it consumes a lot of human resources, requiring a large number of medical staff to participate in drug dispensing and delivery, which not only increases labor costs but also distracts medical staff from patient care. Fifth, it is difficult to track and manage. Manually recording drug distribution and usage makes it difficult to track drug flow and manage inventory, which is not conducive to optimizing resource utilization and ensuring drug safety.

[0003] Although different delivery robots and robotic carts have appeared on the market, the maintenance and daily upkeep of such equipment require a high cost. Secondly, these devices are equipped with many electronic components, and electronic control methods are mostly used when storing and placing medicines. However, electronic control methods are easily affected by factors such as the environment and work intensity during actual use, causing equipment failure. This method is far inferior to a purely mechanical storage and placement system. The pure mechanical structure reduces the use of electronic components, has more reliable control, a long service life, and low maintenance and servicing costs. Summary of the Invention

[0008] Preferably, two limiting pins and two limiting grooves are provided at each end of the medicine-containing box body, and the limiting pins are located above the limiting grooves.

[0009] Preferably, the connecting rod mechanism includes a first pressure arm, a second pressure arm, a sliding wheel, a first movable arm, a second movable arm, a connecting column and a tension spring. The first pressure arm and the second pressure arm are movably mounted on the connecting pin, and the tops of the first pressure arm and the second pressure arm are movably mounted with sliding wheels respectively. The bottoms of the first pressure arm and the second pressure arm are movably connected to the first movable arm and the second movable arm. The other ends of the first movable arm and the second movable arm are connected to corresponding fixed pins. A connecting column is also provided on the first pressure arm and the second pressure arm, and the two connecting columns are fixedly connected by a tension spring.

[0010] Preferably, the locking mechanism includes a pressure plate, a fixed block, a lock tongue control block, a movable groove, an arc track groove, a lock tongue, a guide column, a positioning plate, a compression spring and an adjusting screw. A straight slot is provided on the pressure plate, and the bottom of the pressure plate is fixedly connected to the top of the lock tongue control block. The lock tongue control block is movably installed in the fixed block, and the fixed block is fixedly installed at both ends of the medicine box body, and the fixed block is connected to the channel. A movable groove is also provided in the middle of the lock tongue control block, and arc track grooves are provided on both sides of the inner side of the movable groove.

[0012] Preferably, sliding grooves are provided on both sides of the inner wall of the fixing block, and limiting strips are also provided on both sides of the lock tongue control block, and the limiting strips are located in the sliding grooves.

[0013] Preferably, the present invention also provides a method for using the intelligent rail box-type logistics automatic retractable system, comprising the following specific steps:

[0014] S1: When using this device, first, the smart car is driven along the track to the medicine storage room according to the control instructions. During this process, the control system of the smart car will control the drive motor to rotate. When the drive motor rotates, the driving gear will cause the two driven gears on the left and right to rotate, thereby lifting the medicine box connected to the flat rope;

[0015] S2: As the medicine-loading box gradually approaches the bottom of the intelligent trolley, the first pressing arms at both ends of the medicine-loading box and the sliding wheels on the tops of the second pressing arms will contact the bottom of the intelligent trolley. At this time, as the flat rope is tightened, the intelligent trolley will make the first pressing arms and the second pressing arms rotate around the connecting pin. During this process, the upper and lower parts of the first pressing arms and the second pressing arms will move away from each other, which will cause the first movable arm and the second movable arm connected to the first pressing arm and the second pressing arm to move. During the movement, the first movable arm and the second movable arm will drive the left flap and the right flap to retract until the fixing pin reaches the limit slot;

[0016] S3: After the left and right flaps are folded, continue to tighten the flat rope. At this time, the top of the pressure plate contacts the bottom of the smart cart, which will push the pressure plate down. During the downward movement of the pressure plate, the lock tongue control block will be pushed down in the fixed block. At this time, as the lock tongue control block moves down, under the action of the compression spring, the lock tongue inside the lock tongue control block will gradually extend out of the channel, locking the left and right flaps. At the same time, the bottom of the lock tongue control block exceeds the medicine box to prevent the medicine from falling during transportation.

[0017] S4: When taking medicine, the medicine is directly placed into the medicine box through the intelligent robot, and then the intelligent trolley is transported along the track to the designated platform through the control system. After arriving, the drive motor is reversed to release the flat rope, which moves downward under the action of gravity. When the protruding part of the bottom of the lock tongue control block first contacts the platform, the lock tongue control block moves upward, which will cause the locked lock tongue to move out of the channel. This process compresses the compression spring. After the lock tongue control block is completely moved up into the fixed block, the locking process is released. At this time, the drive motor rotates forward, and in the process of lifting the medicine box off the platform, under the action of the tension spring, the left flap and the right flap will be stretched open, so that the medicine can fall down, and then the medicine is released. A closed-loop process can complete the taking and releasing of medicines, completely replacing manual labor and with higher efficiency.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention adopts an intelligent trolley to pull the medicine box to collect and release medicines, replacing the traditional manual medicine dispensing process. The medicines can be delivered to different medicine collection platforms through the intelligent trolley. This process avoids problems such as delayed medicine delivery, inaccurate medicine dispensing, and untimely tracking and management. In the process of dispensing medicines, the medicine box is in close contact with the bottom of the intelligent trolley, and the structure is more compact, which not only improves the distribution efficiency but also saves labor costs.

[0020] 2. The present invention adopts a purely mechanical mechanism. When storing and releasing medicines, the opening and closing of the left and right flaps are realized by a connecting rod mechanism, and in order to prevent the medicines from falling, they are locked by a locking mechanism. The structure is simple and has high stability. Unlike the delivery carts controlled by electronic devices, it will not cause problems such as medicines falling and equipment being unable to be stored and released. It has a long service life and low repair and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 1

[0038] See also Figure 1 , an intelligent track box-type logistics automatic retractable system includes a track 1, an intelligent trolley 2, a flat rope 3, a retractable medicine box 4, a connecting rod mechanism 5 and a locking mechanism 6. The track 1 is arranged indoors as needed, and the intelligent trolley 2 is mounted on the track 1. The retractable medicine box 4 includes a medicine-loading box body 40 and a protective shell 41. The medicine-loading box body 40 is a box body with upper and lower openings. Adjustment plates 7 are fixedly provided at both ends of the medicine-loading box body 40. A winch mechanism 8 is also provided inside the intelligent trolley 2. The winch mechanism 8 is fixedly connected to the corresponding adjustment plate 7 through a flat rope 3. Connecting pins 9 are also fixedly provided at both ends of the medicine-loading box body 40. Both ends of the medicine-loading box body 40 are equipped with a connecting rod mechanism 5 and a locking mechanism 6. The rod mechanism 5 and the locking mechanism 6 are respectively movably connected to the connecting pin 9, and the protective shell 41 partially wraps the connecting rod mechanism 5 and the locking mechanism 6. The left flip shaft 10 and the right flip shaft 11 are also installed on both sides of the bottom of the medicine box 40. The left flip shaft 10 and the right flip shaft 11 are respectively provided with a left flip plate 12 and a right flip plate 13. The connecting rod mechanism 5 mainly controls the opening and closing of the left flip plate 12 and the right flip plate 13. Channels 14 are also opened at both ends of the medicine box 40. The outer end of the channel 14 cooperates with the locking mechanism 6. The locking mechanism 6 mainly controls whether the left flip plate 12 and the right flip plate 13 are locked. During the process of drug delivery, the left flip plate 12 and the right flip plate 13 at the bottom of the medicine box 4 are always in a closed state.

[0039] The hoisting mechanism 8 includes a driving motor 80, a driving gear 81, a driven gear 82, a rotating rod 83 and a fixed pulley 84. The driving motor 80 is installed inside the intelligent trolley 2, and the output end of the driving motor 80 is connected to the driving gear 81. The driving motor 80 is connected to the control system of the intelligent trolley 2. Two rotating rods 83 and two fixed pulleys 84 are also arranged inside the intelligent trolley 2. The two rotating rods 83 are located between the two fixed pulleys 84. One end of each rotating rod 83 is fixedly connected to the driven gear 82, and the two driven gears 82 are respectively engaged with the driving gear 81. Each rotating rod 83 is fixedly connected to the top of the flat rope 3, and each flat rope 3 is in contact with the adjacent fixed pulley 84. When the driving motor 80 receives the tightening and releasing instructions, it will drive the driven gears 82 on both sides to rotate. The rotation of the driven gear 82 will drive the rotating rod 83 to rotate, so that the rotating rod 83 will drive the flat rope 3 to tighten upward or release downward, which will lift or lower the retractable medicine box 4. The fixed pulley 84 mainly plays a guiding role to reduce the wear of the flat rope 2.

[0040] See Figure 7-8 A fixing pin 15 is provided at both ends of the left flap 12 and the right flap 13, and the fixing pin 15 is movably connected to the corresponding connecting rod mechanism 5. In this way, during the action of the connecting mechanism 5, the fixing pin 15 is driven to move, so that the left flap 12 and the right flap 13 can be opened and closed.

[0041] Each end of the medicine box 40 is provided with two limit pins 16 and two limit slots 17, and the limit pins 16 are located above the limit slots 17. The limit pins 16 mainly serve as limiters, that is, when the first movable arm 53 and the second movable arm 54 are in the opening process and until they contact the two limit pins 16, the bottom of the medicine box 40 is in the maximum open state. The limit slots 17 also serve as limiters, that is, when the connecting mechanism 5 drives the left flap 12 and the right flap 13 to approach each other, the fixing pin 15 gradually moves into the limit slots 17 until they contact the limit slots 17, at which point the left flap 12 and the right flap 13 are completely in the same horizontal plane.

[0042] See Figure 7-13The connecting rod mechanism 5 includes a first pressing arm 50, a second pressing arm 51, a sliding wheel 52, a first movable arm 53, a second movable arm 54, a connecting column 55, and a tension spring 56. The first pressing arm 50 and the second pressing arm 51 are movably installed on the connecting pin 9, and the connecting pin 9 is fixed to both ends of the medicine charging box 40. The first pressing arm 50 and the second pressing arm 51 are movably connected to the connecting pin 9, and the tops of the first pressing arm 50 and the second pressing arm 51 are movably installed with sliding wheels 52. The sliding wheels 52 can rotate, which can reduce friction when in contact with the bottom of the smart car 2. To reduce the noise caused by friction, the bottoms of the first pressing arm 50 and the second pressing arm 51 are movably connected to the first movable arm 53 and the second movable arm 54. The other ends of the first movable arm 53 and the second movable arm 54 are connected to the corresponding fixing pins 15. In this way, the left flap 12 and the right flap 13 can be connected through the first movable arm 53 and the second movable arm 54. A connecting column 55 is also provided on the first pressing arm 50 and the second pressing arm 51. The two connecting columns 55 are fixedly connected by a tension spring 56. The tension spring 56 mainly plays a positioning role, which is specifically divided into opening and closing:

[0043] Opening principle:

[0044] In the initial state, that is, the left flap 12 and the right flap 13 are completely horizontally supported and arranged, and the locking mechanism 6 is not unlocked. When the medicine inside the medicine box 40 needs to be put down, the smart car 2 is first transported to the designated platform along the track 1 through the control system. After arriving, the driving motor 80 is reversed to release the flat rope 3. At this time, it moves downward under the action of gravity. After the downward movement starts, the tension spring 56 is still in a stretched state; until the protruding part of the bottom of the lock tongue control block 62 first contacts the platform, at this time the lock tongue control block 62 moves up, and the upward movement During the process, the guide post 66 of the lock tongue 65 will move the lock tongue 65 to the outside away from the channel 12 under the action of the arc track groove 64. During this process, the lock tongue 65 will compress the compression spring 68, which will cause the locked lock tongue 65 to move out of the channel 14. After the lock tongue control block 62 is completely moved up to the fixed block 61, the locking process is released. At this time, the drive motor 80 rotates forward and will lift the medicine box 4 off the platform. At this time, under the contraction of the tension spring 56, the left flap 12 and the right flap 13 will be stretched open, so that the medicine can fall down.

[0045] Closing principle:

[0046] When it is necessary to load medicine, the smart trolley 2 first controls the driving motor 80 to rotate, so that the flat rope 3 is tightened. As the medicine loading box 40 gradually approaches the bottom of the smart trolley 2, the first pressure arm 50 at both ends of the medicine loading box 40 and the sliding wheel 52 on the top of the second pressure arm 51 will contact the bottom of the smart trolley 2. At this time, as the flat rope 3 is tightened, the smart trolley 2 will make the first pressure arm 50 and the second pressure arm 51 rotate around the connecting pin 9. During this process, the upper and lower parts of the first pressure arm 50 and the second pressure arm 51 will move away from each other, which will cause the first movable arm 53 and the second movable arm 54 connected to the first pressure arm 50 and the second pressure arm 51 to move. During the movement, the first movable arm 53 and the second movable arm 54 will drive the left flap 12 and the right flap 13 to retract until the fixing pin 15 reaches the limit groove 17, which is now in a closed state. However, medicines cannot be put in under this state. Once the medicines are too heavy, the drive motor 80 will be burned out. Therefore, a locking mechanism 6 is designed. When the fixing pin 15 reaches the limit groove 17, the lock tongue control block 62 also reaches the inside of the fixing block 61. At this time, the lock tongue 65 just extends out of the channel 14, thereby completely locking the medicine to prevent it from falling during transportation.

[0047] See Figure 6-13 , the locking mechanism 6 includes a pressure plate 60, a fixed block 61, a lock tongue control block 62, a movable groove 63, an arc track groove 64, a lock tongue 65, a guide column 66, a positioning plate 67, a compression spring 68, and an adjusting screw 69. A straight slot 18 is provided on the pressure plate 60, and the pressure plate 60 is sleeved on the connecting pin 9 through the straight slot 18. The bottom of the pressure plate 60 is fixedly connected to the top of the lock tongue control block 62. The lock tongue control block 62 is movably installed in the fixed block 61. The fixed blocks 61 are respectively fixedly installed at both ends of the medicine box 40, and the fixed block 61 is connected to the channel 14. A movable groove 63 is also provided in the middle of the lock tongue control block 62, and the inner sides of the movable groove 63 are opened. An arc-shaped track groove 64 is provided, which is a component for controlling the movement of the lock tongue 65. In the process of moving the lock tongue control block 62 up and down, the lock tongue 65 will drive the lock tongue 65 to move left and right under the action of the arc-shaped track groove 64, thereby controlling the lock tongue 65. Guide columns 66 are fixedly provided on both sides of the lock tongue 65. The lock tongue 65 is located in the movable groove 63, and the protruding end of the guide column 66 is located in the arc-shaped track groove 64. A positioning plate 67 is also fixedly provided at the outer end of the fixed block 61, and an adjusting screw 69 is threadedly mounted on the positioning plate 67. A compression spring 68 is also fixedly provided at the tail of the lock tongue 65, and the other end of the compression spring 68 is in contact with the adjusting screw 69.

[0048] Locking principle:

[0049] When locking, the pressure plate 60 pushes the lock tongue control block 62 downward. During the pushing process, the guide posts 66 on both sides of the lock tongue 65 will slide along the arc track groove 64, and the lock tongue 65 will only move horizontally to the left and right, and will not move up and down. In this way, as the lock tongue control block 62 descends, under the pressure of the compression spring 68, the front end of the lock tongue 65 will be pushed out of the channel 14, so that the front end of the lock tongue 65 will block the closed contact part between the left flap 12 and the right flap 13, so that the left flap 12 and the right flap 13 will not open as the amount of medicines increases, thus preventing the medicines from falling. When the lock is released, the bottom of the lock tongue control block 62 contacts the platform, and under the action of gravity, the medicine box 40 drops as a whole, causing the lock tongue control block 62 to move upward. When moving upward, the lock tongue 65 will gradually retract, that is, compress the compression spring 68, so that the front end of the lock tongue 65 blocking the contact part between the left flap 12 and the right flap 13 will be retracted into the channel 14, so that the lock will be released. Then, during the rising process of the flat rope 3, under the action of the tension spring 56, the left flap 12 and the right flap 13 gradually move along with the fixed pin 15, thereby opening the left flap 12 and the right flap 13, so that the medicines fall automatically, thereby completing the delivery of the medicines.

[0050] The extending end of the guide column 66 is further provided with a roller 19 , which contacts the inner wall of the arc-shaped track groove 64 . The roller 19 can reduce friction and make driving more convenient.

[0051] The inner wall of the fixing block 61 is provided with grooves 20 on both sides, and the locking tongue control block 62 is also provided with limit bars 21 on both sides. The limit bars 21 are located within the grooves 20. The grooves 20 are mainly used to prevent the locking tongue control block 62 from rocking left and right, thereby preventing wear on the locking tongue 65.

[0052] The present invention also provides a method for automatically retracting and releasing an intelligent rail box-type logistics system, comprising the following specific steps:

[0053] S1: When using the device, first, the smart car 2 is controlled by the control command along the track 1 to the medicine storage chamber. During this process, the control system of the smart car 2 will control the drive motor 80 to rotate. When the drive motor 80 rotates, the driving gear 81 will cause the left and right driven gears 82 to rotate, thereby lifting the medicine box 40 connected to the flat rope 3;

[0054] S2: As the medicine loading box 40 gradually approaches the bottom of the smart trolley 2, the first pressing arms 50 at both ends of the medicine loading box 40 and the sliding wheels 52 on the top of the second pressing arms 51 will contact the bottom of the smart trolley 2. At this time, as the flat rope 3 is tightened, the smart trolley 2 will make the first pressing arm 50 and the second pressing arm 51 rotate around the connecting pin 9. During this process, the upper and lower parts of the first pressing arm 50 and the second pressing arm 51 will move away from each other, which will cause the first movable arm 53 and the second movable arm 54 connected to the first pressing arm 50 and the second pressing arm 51 to move. During the movement, the first movable arm 53 and the second movable arm 54 will drive the left flap 12 and the right flap 13 to retract until the fixing pin 15 reaches the limit slot 17;

[0055] S3: After the left flap 12 and the right flap 13 are folded up, the flat rope 3 is tightened. At this time, the top of the pressure plate 60 contacts the bottom of the smart cart 2, which will push the pressure plate 60 downward. During the downward movement of the pressure plate 60, the lock tongue control block 62 is pushed downward in the fixed block 61. At this time, as the lock tongue control block 62 moves downward, under the action of the compression spring 68, the lock tongue 65 inside the lock tongue control block 62 will gradually extend out of the channel 14, locking the left flap 12 and the right flap 13 to prevent the medicine from falling during transportation. At the same time, the bottom of the lock tongue control block 62 exceeds the bottom surface of the medicine box 40.

[0056] S4: When taking medicine, the medicine is directly placed into the medicine-filled box 40 by the intelligent robot, and then the intelligent trolley 2 is transported to the designated platform along the track 1 through the control system. After arriving, the driving motor 80 is reversed to release the flat rope 3, which moves downward under the action of gravity. When the protruding part of the bottom of the lock tongue control block 62 first contacts the platform, the lock tongue control block 62 moves upward, which will cause the locked lock tongue 65 to move out of the channel 14. This process compresses the compression spring 68. After the lock tongue control block 62 is completely moved up into the fixed block 61, the locking process is released. At this time, the driving motor 80 rotates forward, and in the process of lifting the medicine-filled box 40 off the platform, under the action of the tension spring 56, the left flap 12 and the right flap 13 will be stretched open, so that the medicine can fall down, and then the medicine is released. A closed-loop process can complete the taking and releasing of medicines, completely replacing manual labor, and with higher efficiency.

[0057] Working principle of the present invention:

[0058] When taking medicines, the present invention is in the initial state, that is, the left flap 12 and the right flap 13 are completely horizontally supported and arranged, and the locking mechanism 6 is not unlocked. When it is necessary to transport medicines, the smart trolley 2 first sends the medicine box 4 to the medicine storage chamber, and directly puts the medicine into the medicine box 40. Then, the smart trolley 2 is transported to the designated platform along the track 1 through the control system. After arriving, the driving motor 80 is reversed to release the flat rope 3. At this time, it moves downward under the action of gravity. After the downward movement starts, the tension spring 56 is still in a stretched state until the protruding part of the bottom of the lock tongue control block 62 first contacts the platform. At this time, the lock tongue control block 62 moves up. During the upward movement, the guide post 66 of the lock tongue 65 will move the lock tongue 65 to the outside away from the channel 12 under the action of the arc track groove 64. During this process, the lock tongue 65 will compress the compression spring 68, which will cause the locked lock tongue 65 to move out of the channel 14. After the lock tongue control block 62 is completely moved up to the fixed block 61, the locking process is released. At this time, the drive motor 80 rotates forward to lift the medicine box 4 off the platform. At this time, under the contraction action of the tension spring 56, the left flap 12 and the right flap 13 will be stretched open, so that the medicine can fall down. When all the medicines are put down, continue to control the tightening of the flat rope 3. As the medicine box 40 gradually approaches the bottom of the smart cart 2, the first pressure arms 50 at both ends of the medicine box 40 and the sliding wheels 52 on the top of the second pressure arms 51 will contact the bottom of the smart cart 2. At this time, as the flat rope 3 is tightened, the smart cart 2 will make the first pressure arm 50 and the second pressure arm 51 rotate around the connecting pin 9. During this process, the upper and lower parts of the first pressure arm 50 and the second pressure arm 51 will move away from each other, which will cause the first movable arm 53 and the second movable arm 54 connected to the first pressure arm 50 and the second pressure arm 51 to move. During the movement, the first movable arm 53 and the second movable arm 54 will drive the left flap 12 and the right flap 13 to retract until the fixing pin 15 reaches the limit slot 17, and it is in a closed state at this time. When the fixing pin 15 reaches the limiting groove 17, the locking tongue control block 62 also reaches the inside of the fixing block 61. At this time, the locking tongue 65 just extends out of the channel 14, thereby completely locking the medicine to prevent it from falling during the delivery process.

7. The intelligent rail box-type logistics automatic retractable system according to any one of claims 1 to 6, characterized in that: The method for using the intelligent rail box-type logistics automatic retracting and releasing system includes the following steps: S1: When using the device, first, the intelligent trolley (2) is moved along the track (1) to the medicine storage chamber according to the control instruction. During this process, the control system of the intelligent trolley (2) controls the driving motor (80) to rotate. When the driving motor (80) rotates, the driving gear (81) causes the left and right driven gears (82) to rotate, thereby lifting the medicine box (40) connected to the flat rope (3); S2: As the medicine-filled box (40) gradually approaches the bottom of the intelligent trolley (2), the first pressing arms (50) at both ends of the medicine-filled box (40) and the sliding wheels (52) at the top of the second pressing arms (51) will contact the bottom of the intelligent trolley (2). At this time, as the flat rope (3) is tightened, the intelligent trolley (2) will cause the first pressing arm (50) and the second pressing arm (51) to rotate around the connecting pin (9). During this process, the upper and lower parts of the first pressing arm (50) and the second pressing arm (51) will move away from each other, which will cause the first movable arm (53) and the second movable arm (54) connected to the first pressing arm (50) and the second pressing arm (51) to move. During the movement, the first movable arm (53) and the second movable arm (54) will drive the left flap (12) and the right flap (13) to fold together until the fixing pin (15) reaches the limit groove (17); S3: After the left flap (12) and the right flap (13) are folded up, the flat rope (3) is tightened. At this time, the top of the pressure plate (60) contacts the bottom of the smart car (2), which will push the pressure plate (60) downward. During the downward movement of the pressure plate (60), the lock tongue control block (62) is pushed downward in the fixed block (61). At this time, as the lock tongue control block (62) moves downward, under the action of the compression spring (68), the lock tongue (65) inside the lock tongue control block (62) will gradually extend out of the channel (14), and the left flap (12) and the right flap (13) are locked to prevent the medicine from falling during the transportation process. At the same time, the bottom of the lock tongue control block (62) exceeds the bottom surface of the medicine box (40); S4: When taking medicine, the medicine is directly placed into the medicine storage box (4) by the intelligent robot, and then the intelligent trolley (2) is transported to the designated platform along the track (1) by the control system. After arriving, the driving motor (80) is reversed to release the flat rope (3). At this time, it moves downward under the action of gravity. When the protruding part of the bottom of the lock tongue control block (62) first contacts the platform, the lock tongue control block (62) moves upward, so that the locked lock tongue (65) moves out of the channel (14). This process compresses the compression spring (68). After the lock tongue control block (62) is completely moved upward into the fixed block (61), the locking process is released. At this time, the driving motor (80) rotates forward, and in the process of lifting the medicine box (40) off the platform, under the action of the tension spring (56), the left flap (12) and the right flap (13) will be stretched open, so that the medicine can fall down, and then the medicine is released. A closed-loop process can complete the taking and releasing of medicine, completely replacing manual labor and with higher efficiency.
