Description

Technical Field

[0001] The invention belongs to the field of self-service medicine vending machines, and in particular relates to a plate medicine packaging device applied to the self-service medicine vending machines. Background Art

[0002] With the development of society and the changes in people's living needs, the convenience and timeliness of drug purchases have attracted more and more attention. Self-service drug vending machines, as a new type of drug retail equipment, came into being under such a background, meeting people's needs for convenient drug purchases, greatly shortening the distance for consumers to obtain drugs, and improving the convenience of drug purchases.

[0003] At present, most of the existing self-service medicine vending machines mainly sell whole boxes of medicines. Although this sales method can meet the needs of some consumers to purchase a certain amount of medicines at one time, for some consumers who only need a small amount of medicines for emergency use, or only need to use a single board of certain medicines, buying a whole box not only causes drug waste, but also increases the economic burden. For example, consumers may only need to take one or two medicines to relieve the symptoms of occasional headaches or colds. At this time, buying a whole box of medicines is obviously not economical and environmentally friendly.

[0004] In addition, current self-service medicine vending machines generally lack an effective packaging structure. After consumers purchase medicines, they can only take the medicines away in pieces by themselves, which is not convenient to carry and is not conducive to protecting the integrity and cleanliness of the medicines. This problem is particularly prominent in the scenario of medicine delivery. When the delivery riders pick up the medicines, due to the lack of appropriate packaging measures, the medicines are easily collided and squeezed during transportation, resulting in damage to the medicine packaging or even damage to the medicines themselves. Moreover, scattered medicines cannot provide privacy protection for consumers, and people around them can easily see the information of the purchased medicines. This is an extremely unfriendly experience for buyers of some medicines that involve personal privacy (such as medicines for treating special diseases, health care products, etc.). Summary of the invention

[0005] The purpose of the present invention is to develop a board medicine packaging device for use in self-service medicine vending machines, in response to the difficulties in the existing self-service medicine vending machines in the drug selling and packaging links, and to enable it to have both single-board drug selling and efficient packaging functions, so as to greatly improve the convenience and safety of drug selling services.

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is: a plate medicine packaging device applied to a self-service medicine vending machine, which includes a base frame, a medicine loading area is arranged on the surface of the base frame, a movable track is arranged on one side of the medicine loading area, and a bag taking mechanism is installed on the upper end of the movable track for horizontal sliding along the length direction of the base frame; a bag opening and sealing mechanism and a packaging bag storage bin are arranged in sequence along the length direction of the base frame on the other side of the medicine loading area, the bag opening and sealing mechanism can be arranged opposite to the bag taking mechanism, and the packaging bag storage bin can be arranged opposite to the bag taking mechanism; an auxiliary bracket is arranged above the medicine loading area, a plate medicine storage and dispensing mechanism is arranged on the upper end of the auxiliary bracket, a medicine hopper is arranged at the discharging end of the plate medicine storage and dispensing mechanism, and the discharging end of the medicine hopper is located above the medicine loading area. At this time, when applying the plate medicine packaging device for self-service medicine vending machines provided by the present invention, the bulk plate medicine can be placed in the plate medicine storage and dispensing mechanism, and the packaging bag can be placed in the packaging bag storage bin, and when it is necessary to take the medicine and pack it, the bag taking mechanism is first controlled to move to a position relative to the packaging bag storage bin, and perform the bag taking action; then the bag taking mechanism is controlled to move to a position relative to the bag opening and sealing mechanism, and cooperates with the bag opening and sealing mechanism to perform the bag opening action to open the packaging bag; then, it can first control the plate medicine storage and dispensing mechanism to output the plate medicine into the medicine hopper, and then control the medicine hopper to flip, so as to output the plate medicine in the medicine hopper into the opened packaging bag, and in this process, it can release one plate at a time, that is, control the plate medicine storage and dispensing mechanism to release only one plate medicine each time, and control the medicine hopper to flip and discharge the material once each time it receives a plate medicine, so as to ensure that the entire device can accurately output the corresponding number of plate medicines; finally, it can seal the packaging bag after the medicine is loaded through the action of the bag opening and sealing mechanism to realize the final packaging action, so as to facilitate users to carry medicines and enhance user experience.

[0007] Furthermore, the bag taking mechanism includes a movable bracket installed on a moving track for horizontal sliding along the length direction of the base frame, and the movable bracket is connected to a linear drive mechanism 1 for transmission; a bag taking bracket is installed on the upper end of the movable bracket for horizontal sliding along the width direction of the base frame, and the bag taking bracket is connected to a linear drive mechanism 2 for transmission; a vacuum bag taking nozzle is arranged at the end of the bag taking bracket, and the vacuum bag taking nozzle is connected to an air pump through a pipeline, and the state of the vacuum bag taking nozzle can be controlled by the air pump, and the position of the vacuum bag taking nozzle is adjusted by the movement of the bag taking bracket and the movable bracket, that is, the entire bag taking mechanism is controlled to move between the packaging bag storage bin and the bag opening and sealing mechanism through the movement of the movable bracket to realize the corresponding bag taking action and bag opening and material receiving action; the position of the vacuum bag taking nozzle is controlled to adjust by the movement of the bag taking bracket to ensure that the vacuum bag taking nozzle can adsorb the packaging bags in the packaging bag storage bin, and ensure that the packaging bags adsorbed at the vacuum bag taking nozzle can be adsorbed by the bag opening and sealing mechanism.

[0008] Further, a bag picking sensor is provided at the end of the bag picking bracket. When the bag picking mechanism is disposed opposite to the packaging bag storage bin, the detection end of the bag picking sensor faces the packaging bag storage bin. At this time, it can be determined whether the vacuum bag picking suction nozzle has adsorbed the packaging bag through the bag picking sensor. That is, when the vacuum bag picking suction nozzle adsorbs the packaging bag, the bag picking sensor can detect whether there is an obstacle within a certain range in front of it. When an obstacle is detected, it is concluded that the packaging bag has been adsorbed; when no obstacle is detected, it is concluded that the packaging bag has not been adsorbed. Preferably, the bag picking sensor can be a common laser sensor, ultrasonic sensor, infrared sensor, etc.

[0009] Further, the bag opening and sealing mechanism includes two parallel optical axes. At one end of the two optical axes facing the medicine loading area, a first mounting plate is commonly installed. A heat sealing heating strip is fixedly installed on the first mounting plate. At the other end of the two optical axes away from the medicine loading area, a second mounting plate is commonly installed. A heat sealing bracket is horizontally slidably installed along the width direction of the chassis in the middle of the two optical axes. A vacuum bag opening suction nozzle is provided on one side of the heat sealing bracket facing the medicine loading area. The vacuum bag opening suction nozzle is connected to an air pump through a pipeline. The heat sealing bracket is fixedly installed on the auxiliary bracket. A sliding rod is horizontally slidably installed along the width direction of the chassis on the heat sealing bracket. A heat sealing heating strip is also provided at one end of the sliding rod facing the medicine loading area. A pull rod is provided at the other end of the sliding rod away from the medicine loading area. A third linear driving mechanism is provided between the pull rod and the second mounting plate. The third linear driving mechanism is installed on the heat sealing bracket. The third linear driving mechanism can drive the heat sealing bracket and the optical axis to move relative to each other, and drive the sliding rod and the heat sealing bracket to move relative to each other, so as to control the two heat sealing heating strips to approach each other to achieve the corresponding bag sealing operation.

[0010] Further, the third linear driving mechanism includes a support plate fixedly installed on the heat sealing bracket. A rotating shaft is rotatably installed on the surface of the support plate. One end of the rotating shaft is drivingly connected to a rotating drive motor. The other end of the rotating shaft is drivingly connected to the middle of a crank. Two ends of the crank are respectively rotatably installed with a first connecting rod and a second connecting rod. The end of the first connecting rod is hinged to the pull rod. The end of the second connecting rod is hinged to the second mounting plate. At this time, the first connecting rod, the second connecting rod, and the crank will jointly form a crank connecting rod mechanism. Under the action of this crank connecting rod mechanism and the rotating drive motor, the pull rod and the heat sealing heating strip are controlled to approach each other to achieve the corresponding bag sealing operation.

[0011] Furthermore, a detection plate is provided on the slide bar, and a closing sensor and an opening sensor are sequentially provided at the end of the support plate in a direction away from the charging area. When the slide bar moves along the width direction of the base, the detection plate can pass through the closing sensor and the opening sensor, and respectively block the detection ends of the closing sensor and the opening sensor at the corresponding positions, so as to judge the state of the packaging bag by the detection results of the closing sensor and the opening sensor. And preferably, the closing sensor and the opening sensor can adopt common laser sensors, ultrasonic sensors, infrared sensors, etc. And when it adopts a laser sensor, it can work by relying on the laser beam it emits. That is, when the object blocks the propagation of the laser beam, the sensor does not receive the reflected signal, so as to judge that the detection plate is located at the position of the corresponding sensor; and it has high measurement accuracy and fast response speed. When it adopts an ultrasonic sensor, it can determine the state of the object by emitting and receiving ultrasonic waves. When the ultrasonic wave encounters an object and is reflected back, according to the time and intensity of the reflected wave, the corresponding sensor can determine the position and state of the detection plate, so as to accurately judge whether the packaging bag is in a closed or open state, and effectively avoid failures caused by poor sealing. When it adopts an infrared sensor, it can obtain the state information of the object by emitting and receiving infrared rays. When the emitted infrared rays are blocked or reflected by the detection plate, the corresponding sensor can quickly and accurately determine the position of the object based on the changes in the infrared rays, thereby accurately determining whether the packaging bag is in a closed or open state, effectively avoiding failures caused by poor sealing.

[0012] Furthermore, two bag opening paddles are rotatably installed on the side of the heat sealing bracket facing the charging area. Both bag opening paddles are transmission-connected to a rotary servo, and the rotation of the bag opening paddles is controlled by the rotary servo to move the two sides of the packaging bag to ensure that the packaging bag can be fully opened.

[0013] Furthermore, one end of the medicine hopper is hingedly mounted on the auxiliary bracket, and the other end of the medicine hopper is hingedly mounted with a push rod, which is hinged to the auxiliary bracket and can push the medicine hopper to rotate in a vertical plane to achieve a corresponding discharging action.

[0014] Furthermore, a discharge end of the medicine hopper is provided with a cross-shooting sensor, and the cross-shooting sensor is used to determine whether the plate medicine temporarily placed in the medicine hopper has slipped off.

[0015] Furthermore, the bottom frame is provided with a discharging channel in the medicine loading area, and the packaging bags after packaging can be discharged through the discharging channel to facilitate the medicine purchasing personnel to take the medicine.

[0016] As can be seen from the above technical solutions, the present invention has the following advantages: The present invention designs a tablet medicine packaging device applied to an automatic medicine dispenser. When applying the tablet medicine packaging device provided by the present invention for a self-service medicine dispenser, bulk tablet medicines can be placed in the tablet medicine storage and dispensing mechanism, and the packaging bags can be placed in the packaging bag storage bin. When it is necessary to dispense and package medicines, first control the bag-taking mechanism to move to a position opposite to the packaging bag storage bin and perform a bag-taking action; then control the bag-taking mechanism to move to a position opposite to the bag-opening and sealing mechanism and cooperate with the bag-opening and sealing mechanism to perform a bag-opening action to open the packaging bag; subsequently, it can first control the tablet medicine storage and dispensing mechanism to output the tablet medicines into the medicine hopper, and then control the medicine hopper to flip so as to output the tablet medicines in the medicine hopper into the opened packaging bag. Moreover, during this process, it can place one tablet board at a time, that is, control the tablet medicine storage and dispensing mechanism to release only one tablet board each time, and control the medicine hopper to perform a flipping and discharging action every time it receives one tablet board, so as to ensure that the entire device can accurately output the corresponding number of tablet medicines; finally, it can seal the packaging bag after loading the medicines through the action of the bag-opening and sealing mechanism to complete the final packaging action. Therefore, this tablet medicine packaging device has functions such as bag-taking, bag-opening, tablet medicine dispensing, and sealing. It can dispense tablet medicines according to the actual usage amount, which can effectively avoid waste of medicines and can also seal multiple tablet boards at one time, thus facilitating users to carry medicines and enhancing the user experience.

[0022] Among them, a moving track 2 is provided in the mobile device area, and a bag-taking mechanism 4 is horizontally slidably installed at the upper end of the moving track 2 along the length direction of the underframe. Specifically, as Figure 1 、 Figure 2As shown, the bag-taking mechanism 4 includes a moving bracket 407 horizontally and slidably mounted on the moving track 2 along the length direction of the chassis 13. The moving bracket 407 is drivingly connected to a first linear driving mechanism 1, and the first linear driving mechanism 1 can adopt any one of conventional linear driving mechanisms commonly available in the market, such as ball screw driving mechanism, gear rack driving mechanism, synchronous belt driving mechanism, chain driving mechanism, pneumatic linear driving mechanism, hydraulic linear driving mechanism, etc. For example, when it adopts a ball screw driving mechanism, the screw in the ball screw driving mechanism can be rotatably mounted on the chassis 13 or the moving track 2 and drivingly connected to the first driving motor; the nut in the ball screw driving mechanism is mounted together with the moving bracket 407, so as to transmit motion and power through the rolling of the balls between the screw and the nut, convert the rotational motion of the first driving motor into a linear motion, and control the left-right movement of the moving bracket 407. When it adopts a gear rack driving mechanism, the gear in the gear rack driving mechanism can be rotatably mounted on the chassis 13 or the moving track 2 and drivingly connected to the first driving motor; the rack in the gear rack driving mechanism is mounted together with the moving bracket 407, so as to drive the gear to rotate by the first driving motor, drive the rack meshing with the gear to do a linear motion through the gear, and drive the moving bracket 407 to move through the rack.

[0023] Meanwhile, the present invention also horizontally slidably mounts a bag-taking bracket 406 along the width direction of the chassis 13 at the upper end of the mobile bracket 407. The bag-taking bracket 406 is drivingly connected to a second linear driving mechanism 402, and the second linear driving mechanism 402 drives the bag-taking bracket 406 to move in the corresponding direction at the upper end of the mobile bracket 407. Moreover, similar to the first linear driving mechanism 1, the second linear driving mechanism 402 can also adopt any one of the conventional linear driving mechanisms commonly available on the market, such as a ball screw driving mechanism, a gear rack driving mechanism, a synchronous belt driving mechanism, a chain driving mechanism, a pneumatic linear driving mechanism, a hydraulic linear driving mechanism, etc. For example, when it adopts a ball screw driving mechanism, the screw in the ball screw driving mechanism can be rotatably mounted on the mobile bracket 407 and drivingly connected to a second driving motor 401; the nut in the ball screw driving mechanism is mounted together with the bag-taking bracket 406, so as to transmit motion and power through the rolling of the balls between the screw and the nut, convert the rotational motion of the second driving motor 401 into a linear motion, and control the bag-taking bracket 406 to move in the front-rear direction. When it adopts a gear rack driving mechanism, the gear in the gear rack driving mechanism can be rotatably mounted on the mobile bracket 407 and drivingly connected to a second driving motor 401; the rack in the gear rack driving mechanism is mounted together with the bag-taking bracket 406, so that the second driving motor 401 drives the gear to rotate, the gear drives the engaged rack to perform a linear motion, and the rack drives the bag-taking bracket 406 to move. And preferably, a ball screw driving mechanism is adopted. At the end of the bag-taking bracket 406 facing the charging area 12, a vacuum bag-taking suction nozzle 404 is provided, that is, a vacuum bag-taking suction nozzle 404 is provided at the rear end of the medicine-taking bracket. Moreover, the vacuum bag-taking suction nozzle 404 is communicated with an air pump 3 through a pipeline. Thus, the present invention can control the state of the vacuum bag-taking suction nozzle 404 through the air pump 3, and adjust the position of the vacuum bag-taking suction nozzle 404 through the movement of the bag-taking bracket 406 and the mobile bracket 407, so as to ensure that the vacuum bag-taking suction nozzle 404 can perform a sucking action on the packaging bag and ensure that the bag-taking mechanism 4 can complete the bag-taking action.

[0024] In addition, as a preference, the present invention can also provide a bag-taking sensor 405 at the end of the bag-taking bracket 406 facing the charging area 12, that is, a bag-taking sensor 405 is provided at the rear end of the medicine-taking bracket, and the detection end of the bag-taking sensor 405 is arranged facing the charging area 12. At this time, it can judge whether the vacuum bag-taking suction nozzle 404 adsorbs the packaging bag through the bag-taking sensor 405, that is, when the vacuum bag-taking suction nozzle 404 adsorbs the packaging bag, the bag-taking sensor 405 can detect whether there is an obstacle within a certain range in front of it, and when an obstacle is detected, it can conclude that the packaging bag has been adsorbed; when no obstacle is detected, it can conclude that the packaging bag has not been adsorbed. Moreover, as a preference, the bag-taking sensor 405 can adopt common laser sensors, ultrasonic sensors, infrared sensors, etc.

[0025] A discharging channel 11 is provided at one end of the medicine loading area 12, and the packaging bags after packaging can be discharged through the discharging channel 11, so as to facilitate the medicine purchaser to take the medicine.

[0026] The fixed equipment area is sequentially provided with a bag opening and sealing mechanism 5 and a packaging bag storage bin 9 along the length direction of the base frame 13, and the discharge channel 11 is located at the front side of the bag opening and sealing mechanism 5. When the bag taking mechanism 4 moves along the movable track 2, it can be arranged opposite to the bag opening and sealing mechanism 5 and the packaging bag storage bin 9, thereby ensuring that the bag taking mechanism 4 can not only take the bag at the packaging bag storage bin 9, but also move to the top of the discharge channel 11, and cooperate with the bag opening and sealing mechanism 5 to realize the bag opening action, material receiving action and packaging and sealing action.

[0027] Specifically, Figure 3 As shown, the bag opening and sealing mechanism 5 includes two parallel optical axes 605, and a mounting plate 1 610 is commonly installed at one end of the two optical axes 605 facing the medicine charging area 12, and a heat sealing heating strip 608 is fixedly installed on the mounting plate 1 610; a mounting plate 2 611 is commonly installed at one end of the two optical axes 605 away from the medicine charging area 12, and a heat sealing bracket 606 is horizontally slidably installed in the middle of the two optical axes 605 along the width direction of the bottom frame 13, and a vacuum bag opening suction nozzle 609 is arranged at one end of the heat sealing bracket 606 facing the medicine charging area 12, and the vacuum bag opening suction nozzle 609 is connected to the air pump 3 through a pipeline. Two bag opening paddles 607 are rotatably installed on one side of the heat sealing bracket 606 facing the medicine charging area 12, and the two bag opening paddles 607 are both transmission-connected to a rotary steering gear 612, and the rotation of the bag opening paddles 607 is controlled by the rotary steering gear 612 to paddle the two sides of the packaging bag to ensure that the packaging bag can be fully opened. The heat sealing bracket 606 is horizontally slidably installed with a slide bar 618 along the width direction of the base frame 13, and a heat sealing heating strip 608 is also arranged on the end of the slide bar 618 facing the charging area 12, and a pull rod 619 is arranged on the end of the slide bar 618 away from the charging area 12, and a linear drive mechanism three is arranged between the pull rod 619 and the second mounting plate 611, and the linear drive mechanism three can adopt any one of the conventional linear drive mechanisms commonly seen on the market, such as ball screw transmission mechanism, gear rack transmission mechanism, synchronous belt transmission mechanism, chain transmission mechanism, pneumatic linear drive mechanism, hydraulic linear drive mechanism, etc., and the heat sealing bracket 606 is driven by the linear drive mechanism three to move linearly along the optical axis 605, so as to control the two heat sealing heating strips 608 to approach each other, so as to realize the corresponding bag sealing operation.

[0028] Moreover, as an optimization, the present invention can be provided with an auxiliary bracket 10 at the upper end of the chassis 13, and the linear drive mechanism three and the entire bag opening and sealing mechanism 5 are installed on the auxiliary bracket 10. At this time, the heat sealing bracket 606 is fixedly installed on the auxiliary bracket 10; the linear drive mechanism three includes a support plate 615 fixedly installed on the heat sealing bracket 606, a rotating shaft 616 is rotatably installed on the surface of the support plate 615, one end of the rotating shaft 616 is drivingly connected to a rotation drive motor 601, the other end of the rotating shaft 616 is drivingly connected to the middle of a crank 604, and both ends of the crank 604 are respectively rotatably installed with a connecting rod one 613 and a connecting rod two 614, the end of the connecting rod one 613 is hinged to a pull rod 619, and the end of the connecting rod two 614 is hinged to a mounting plate two 611. Based on this, the connecting rod one 613, the connecting rod two 614, and the crank 604 together form a crank 604 connecting rod mechanism, and under the action of the crank 604 connecting rod mechanism and the rotation drive motor 601, the two heat sealing heating strips 608 are controlled to approach each other to realize the corresponding bag sealing operation.

[0029] In addition, to facilitate determining the position of the packaging bag and its state, the present invention may further be provided with a detection plate 617 on the sliding rod 618, and a closing sensor 602 and an opening sensor 603 are sequentially arranged at the end of the support plate 615 in a direction away from the medicine loading area 12. At this time, when the sliding rod 618 moves along the width direction of the base, the detection plate 617 can pass by the closing sensor 602 and the opening sensor 603, and respectively block the detection ends of the closing sensor 602 and the opening sensor 603 at the corresponding positions. In this way, the entire device can judge the state of the packaging bag based on the detection results of the closing sensor 602 and the opening sensor 603. That is, when the closing sensor 602 is blocked, it is known that the packaging bag has moved to the heat-sealing position for heat-sealing treatment; when the opening sensor 603 is blocked, it is known that the packaging bag has not moved to the heat-sealing position for heat-sealing treatment and is still in an open state. Moreover, preferably, the closing sensor 602 and the opening sensor 603 can adopt common laser sensors, ultrasonic sensors, infrared sensors, etc. And when it adopts a laser sensor, it can carry out work by virtue of the laser beam it emits. That is, when an object blocks the propagation of the laser beam, the sensor cannot receive the reflected signal, thereby judging that the detection plate is located at the position of the corresponding sensor; and it has high measurement accuracy and fast response speed. When it adopts an ultrasonic sensor, it can determine the state of the object by emitting and receiving ultrasonic waves. When the ultrasonic wave is reflected back by an object, the corresponding sensor can determine the position and state of the detection plate according to the time and intensity of the reflected wave, so as to accurately judge whether the packaging bag is in a closed or open state, effectively avoiding failures caused by insufficient sealing. When it adopts an infrared sensor, it can obtain the state information of the object by emitting and receiving infrared rays. When the emitted infrared rays are blocked or reflected by the detection plate, the corresponding sensor can quickly and accurately judge the position of the object based on the change of the infrared rays, so as to accurately judge whether the packaging bag is in a closed or open state, effectively avoiding failures caused by insufficient sealing.

[0030] In addition, a medicine hopper 8 and a tablet storage and dispensing mechanism 6 are further arranged above the auxiliary bracket 10 in the present invention. Among them, the medicine hopper 8 is located at the discharge end of the tablet storage and dispensing mechanism 6, and the discharge end of the medicine hopper 8 is located above the medicine loading area 12. The lower side of the discharge end of the medicine hopper 8 is hinged and installed on the auxiliary bracket 10. A push rod 7 is hinged and installed on the lower side of the end of the medicine hopper 8 far from the discharge end. The push rod 7 is hinged to the auxiliary bracket 10 and can push the medicine hopper 8 to rotate in the vertical plane to achieve the corresponding discharging action. At the same time, preferably, the present invention may further be provided with a pair of sensors 801 at the discharge end of the medicine hopper 8, and judge whether the tablets temporarily placed in the medicine hopper 8 have slipped through the pair of sensors 801.

[0031] Based on this, when applying the tablet medicine packing device for the self-service medicine vending machine provided by the present invention, the loose tablet medicines can be placed in the tablet medicine storage and dispensing mechanism 6, and the packaging bags can be placed in the packaging bag storage bin 9. When it is necessary to take medicine and perform packing processing, first control the bag-taking mechanism 4 to move to a position opposite to the packaging bag storage bin 9 and perform the bag-taking action; then control the bag-taking mechanism 4 to move to a position opposite to the bag-opening and sealing mechanism 5 and cooperate with the bag-opening and sealing mechanism 5 to perform the bag-opening action to open the packaging bag. Subsequently, it can first control the tablet medicine storage and dispensing mechanism 6 to output the tablet medicines into the medicine hopper 8, and then control the medicine hopper 8 to flip so as to output the tablet medicines in the medicine hopper 8 into the opened packaging bag. Moreover, during this process, it can place one board at a time, that is, control the tablet medicine storage and dispensing mechanism 6 to only release one board of tablet medicine each time, and control the medicine hopper 8 to perform a flipping and discharging action every time it receives one board of tablet medicine, so as to ensure that the entire device can accurately output the corresponding number of tablet medicines. Finally, it can seal the packaging bag after loading the medicine through the action of the bag-opening and sealing mechanism 5 to complete the final packing action, thereby facilitating the user to carry the medicine and enhancing the user experience.

[0032] Moreover, the working process of the self-service medicine vending machine applying the present invention is as follows: After the user completes the medicine purchasing process such as remote consultation, medicine selection, and payment on the self-service medicine vending machine, the self-service medicine vending machine extracts the medication data from the user's prescription information, obtains the optimal number of tablet packs for shipment, and temporarily stores the tablet packs for shipment in the tablet storage and dispensing mechanism 6, waiting for the tablet packs to be packed in bags. After receiving the tablet pack sealing instruction sent by the automatic medicine vending machine, the tablet pack packing device applied to the self-service medicine vending machine first controls the operation of the linear drive mechanism 1, moves the bag-taking mechanism 4 connected thereto to the relative position of the bag storage bin 9. After the bag-taking mechanism 4 reaches the relative position of the bag storage bin 9, the drive motor 401 drives the linear drive mechanism 402 to move. The linear drive mechanism 402 drives the bag-taking support 406 connected thereto to move forward, bringing the vacuum bag-taking suction nozzle 404 into contact with the bags stored in the bag storage bin 9. During this process, since the vacuum bag-taking suction nozzle 404 is fixed to the bag-taking support 406 by a spring, the spring is compressed to generate an elastic force, ensuring that the bag is in close contact with the vacuum bag-taking suction nozzle 404 to prevent air leakage. At the same time, the vacuum bag-taking suction nozzle 404 is connected to the air pump 3 through a trachea. The air pump 3 operates to extract the gas from the vacuum bag-taking suction nozzle 404, forming a negative pressure on the vacuum bag-taking suction nozzle 404. The bag is adsorbed to the vacuum bag-taking suction nozzle 404 under the negative pressure. After completing the above actions, the drive motor 401 moves in the reverse direction to drive the linear drive mechanism 402 to return to the initial position, extracting the bag from the bag storage bin 9. At the same time, the voltage of the sampling bag-taking sensor 405 is measured to ensure that the bag moves with the bag-taking support 406. Moreover, preferably, the present invention can also be provided with a position sensor 403 in the linear drive mechanism 402, and the position of the power output end in the linear drive mechanism 402 is detected by the position sensor 403 to determine whether the drive motor 401 is blocked.

[0033] After the bag taking action is completed, the driving motor 1 rotates forward, driving the linear driving mechanism 1 to move forward, and the bag taking mechanism 4 fixed on the power output end of the linear driving mechanism 1 moves to the relative position of the bag opening and sealing mechanism 5. After the bag taking mechanism 4 reaches the relative position of the bag opening and sealing mechanism 5, the driving motor 2 401 moves forward again to drive the linear driving mechanism 2 402 to move, and controls the bag taking bracket 406 connected to the linear driving mechanism 2 402 to move forward again, so as to separate the packaging bag from the vacuum bag opening mechanism 5. The vacuum bag opening suction nozzle 609 contacts the vacuum bag opening suction nozzle 609, and the vacuum bag opening suction nozzle 609 is connected to the air pump 3 through the air pipe. The air pump 3 extracts the gas from the vacuum bag opening suction nozzle 609, and forms a negative pressure on the vacuum bag opening suction nozzle 609. The packaging bag is adsorbed on the vacuum bag opening suction nozzle 609 by the negative pressure. The vacuum bag taking suction nozzle 404 and the vacuum bag opening suction nozzle 609 respectively adsorb the two sides of the packaging bag, and then the driving motor 2 401 is controlled to move in the opposite direction to drive the bag taking bracket 406 connected to the linear driving mechanism 2 402 to move backward, and at the same time, the bag opening plate 60 7 moves the two sides of the packaging bag to make the packaging bag fully open; after the packaging bag is opened, the plate medicine storage and dispensing mechanism 6 will discharge the plate medicine temporarily stored inside through the medicine dispensing channel, and the plate medicine will fall onto the medicine hopper 8; and when the plate medicine falls onto the medicine hopper 8, the push rod 7 is controlled to extend, pushing the medicine hopper 8 to pour the plate medicine into the packaging bag, and in this process, the present invention can place a travel switch at the front end of the medicine dispensing channel of the plate medicine storage and dispensing mechanism 6, and the travel switch is closed after detecting the plate medicine, and opened after the plate medicine is sent out, so as to be used for the plate medicine delivery action Detection, and used to detect the number of plate medicines shipped; a through-shooting sensor 801 is placed at the discharge end of the medicine hopper 8, and the through-shooting sensor 801 is used to detect whether the plate medicine is sent into the packaging bag by the medicine hopper 8, and if the plate medicine storage and dispensing mechanism 6 temporarily stores multiple plate medicines to be packaged, it can be released one by one, that is, the plate medicine storage and dispensing mechanism 6 is controlled to release only one plate medicine each time, and the medicine hopper 8 is controlled to perform a flipping and unloading action every time it receives a plate medicine, thereby ensuring that the entire device can accurately output the corresponding number of plate medicines.

[0034] When all the plates to be sealed are sent into the packaging bag in turn and there are no plates to be sealed in the plate medicine storage and dispensing mechanism 6, the rotary drive motor 601 rotates forward to drive the crank 604 to rotate clockwise, and the crank 604 drives the connecting rod 1 613 and the connecting rod 2 614 to rotate, thereby controlling the slide bar 618 to move in the closing direction of the packaging bag. When the closing sensor 602 is blocked, the rotary drive motor 601 stops rotating to complete the closing of the packaging bag. At the same time, the heat sealing heating strip 608 heats the packaging bag in a controlled manner to achieve heat sealing of the packaging bag.

[0035] After the heat sealing of the packaging bag is completed, the air pump 3 is controlled to close, and the negative pressure of the vacuum bag-taking suction nozzle 404 and the vacuum bag-opening suction nozzle 609 disappears. At the same time, the rotation drive motor 601 rotates in the reverse direction to drive the crank 604 to rotate counterclockwise. The crank 604 drives the first connecting rod 613 and the second connecting rod 614 to rotate in the reverse direction, thereby controlling the slide rod 618 to move along the optical axis 605 in the opening direction. When the opening sensor 603 is blocked, the rotation drive motor 601 stops rotating. At the same time, the heat-sealed packaging bag falls off from the vacuum bag-taking suction nozzle 404 and the vacuum bag-opening suction nozzle 609, and falls out through the discharge channel 11 to the next mechanism in the self-service medicine vending machine to complete operations such as labeling. The drive motor 1 is installed in reverse to drive the bag-taking mechanism 4 back to the initial position, completing all the operations of packing the tablet medicine.
