[0018] Please see Figures 1 to 6This application provides an automatic bagging device for a medicine filling machine, including a bag-separating part 1, a first conveyor belt 2, a bag-opening part 3, a bag-fitting part 4, and a clamping part 5.

[0019] The bag-separating section 1 includes an automatic lifting and storage mechanism 11, a bag-separating motor 12, and a friction wheel 13 mounted on top of it. The automatic lifting and storage mechanism 11 is used to stack and store packaging bags 7 (e.g., woven bags), and specifically includes a base 111, multiple vertically fixed guide rods 112, a lifting plate 113 that slides along the guide rods (on which the packaging bags 7 are placed), a vertically arranged lead screw 114 (threaded to the lifting plate 113), and a lifting motor 115 mounted on the base 111 (driving the lead screw 114 to rotate). The friction wheel 13 is connected to the drive shaft of the bag-separating motor 12, and its bottom is designed to be close to the topmost packaging bag 7. A first infrared sensor 116 is horizontally arranged on the guide rods 112, at the same height as the bottom surface of the friction wheel 13, for detecting the stacking height of the packaging bags 7 and is electrically connected to the lifting motor 115 to control its start and stop.

[0020] The bag opening section 3 is located at the end of the first conveyor belt 2 (bag-packing area). It includes a gantry frame 31, on which a bag opening cylinder 32 is vertically mounted. A vacuum suction plate 33 is mounted on the piston rod of the bag opening cylinder 32, and multiple suction cups are arranged horizontally on the plate. The suction cups are connected to a vacuum generator through air pipes. A second infrared sensor 34 is also vertically downward mounted on the gantry frame 31 to detect whether the packaging bag 7 is in position, and is electrically connected to the bag opening cylinder 32, the first conveyor belt 2, and the bag-splitting motor 12 to coordinate and control related actions.

[0021] The bagging section 4 is located above the end of the first conveyor belt 2 and cooperates with the bag opening section 3. It includes a rotating shaft 41, a rotary motor 42, and two bagging manipulators 43. The rotating shaft 41 is driven by the rotary motor 42. The two bagging manipulators 43 are symmetrically mounted on the rotating shaft 41. Each manipulator includes an arc-shaped plate 431 fixed at one end to the rotating shaft 41, a spreading plate 432 hinged to the arc-shaped plate 431, and a spreading cylinder 433 for controlling the opening and closing of the spreading plate 432.

[0022] The clamping part 5 is located on both sides of the loading tube 8 (the discharge port of the loading machine). It includes two clamping cylinders 51, which are inclined downwards. An arc-shaped clamping plate 52 is fixed on the piston rod of the cylinder. The arc of the clamping plate is consistent with the arc of the outer surface of the loading tube 8 to facilitate clamping.

[0023] This embodiment also includes a second conveyor belt 6, the front end of which is located directly below the filling tube 8, for supporting the packaging bag 7 and transporting it away after the filling is completed.

[0024] The working process of this utility model is as follows: 1. Bag separation and automatic lifting: such as Figure 2 As shown, the bag-separating motor 12 in the bag-separating section 1 rotates, driving the friction wheel 13 to rotate. Under the action of friction, the friction wheel 13 pushes the topmost of the stacked packaging bags 7 (with their openings all facing the first conveyor belt 2) in the automatic lifting storage mechanism 11 onto the first conveyor belt 2, completing the bag-separating action. After the top packaging bag 7 is sent away, the first infrared sensor 116 detects that the height of the stacked packaging bags 7 is lower than the bag-separating height (i.e., the bottom of the friction wheel 13). At this time, the first infrared sensor 116 controls the lifting motor 115 to operate, driving the lead screw 114 to rotate, causing the lifting plate 113 to rise until the topmost packaging bag 7 contacts the first infrared sensor 116 (reaching the bag-separating height). The lifting motor 115 then stops, preparing for the next bag-separating operation.

[0025] 2. Conveying and Opening: After the packaging bag 7 enters the first conveyor belt 2, it moves with it to the bagging area at the end. When the second infrared sensor 34 on the gantry 31 detects that the packaging bag 7 has arrived, it sends a signal to stop the first conveyor belt 2 and controls the piston rod of the opening cylinder 32 to extend. The opening cylinder 32 drives the vacuum suction plate 33 to move downward until the suction cup adheres to the upper side of the bag opening of the packaging bag 7. Subsequently, the vacuum generator starts to draw a vacuum, the piston rod of the opening cylinder 32 retracts, and drives the vacuum suction plate 33 to move upward, thereby opening the bag opening of the packaging bag 7 to a certain size (e.g., Figure 3 (As shown), complete the bag opening action.

[0026] 3. Bagging and Opening: After the filling machine finishes filling the previous packaging bag 7 and transports it away via the second conveyor belt 6, the rotary motor 42 inside the bagging section 4 rotates clockwise, driving the two bagging manipulators 43 (the arc plate 431 and the opening plate 432 are in a closed state at this time) to rotate downwards, extending into the already opened packaging bag 7. At this time, the suction cup in the vacuum adsorption plate 33 breaks the vacuum (stops pumping), releasing the packaging bag 7, and the piston rod of the bag opening cylinder 32 continues to retract and reset, leaving the bagging area. Next, the piston rod of the opening cylinder 433 on the bagging manipulator 43 extends, pushing the opening plate 432 to rotate, making the angle between the arc plate 431 and the opening plate 432 larger, thereby completely opening and locking the opening of the packaging bag 7 (as shown). Figure 4 (As shown).

[0027] 4. Bag positioning and clamping: The rotary motor 42 rotates in the opposite direction, driving the two bag-feeding robotic arms 43, whose bag openings have been opened, to rotate upwards, accurately placing the bag opening onto the medicine-filling tube 8 (e.g., Figure 5 (As shown). After the bagging action is completed, the piston rod of the clamping cylinder 51 in the clamping part 5 extends, driving the arc-shaped clamping plate 52 to fix and clamp the bag opening on the drug-filling tube 8 from both sides.

[0028] 5. Reset and Cycle: After the clamping part 5 clamps the packaging bag 7, the expansion cylinder 433 retracts, causing the bagging robot arm 43 to release the packaging bag 7. The rotary motor 42 continues to rotate in the opposite direction, driving both bagging robots 43 back to the initial reset position (e.g., ...). Figure 6 (As shown). At this time, the filling tube 8 can begin filling the packaging bag 7 with materials. At the same time, when the second infrared sensor 34 detects that there is no packaging bag 7 in the bagging area (i.e., the packaging bag 7 has been removed), the second infrared sensor 34 will send a signal to the first conveyor belt 2 and the bag-separating motor 12 again, so that it can run again and transport the next packaging bag 7 to the bagging area, in preparation for the next bagging action (the bag-separating motor 12 has been programmed to rotate a specific number of times after receiving the signal to ensure that only one packaging bag 7 is delivered).

[0029] 6. Loading and Discharging: The bottom of the packaging bag 7 is supported on the second conveyor belt 6. After the metering valve in the filling machine loads a specific amount of material into the packaging bag 7, the filling machine sends a signal to the second conveyor belt 6 to operate, transporting the full packaging bag 7 to the next process (such as the sealing process), thus making room for the bagging action of the next empty bag.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
