The packaging bag is placed on the belt conveyor 5 for transportation, and stops after moving to the bottom of the grabbing claw 4; after the angle of the adjustment unit is adjusted, the grabbing claw 4 grabs the packaging bag and moves it upward; the pushing plate 8 pushes the packaging bag to the temporary stacking plate 6 for placement; after placing a packaging bag, the lifting screw machine 7 drives the temporary stacking plate 6 to move downward, gradually overlapping multiple packaging bags, and completing temporary stacking above the belt conveyor 5; the longitudinal component 2 and the transverse component 3 drive the entire storage assembly to move, and move to the area on both sides of the belt conveyor 5 for stacking; all the packaging bags on the temporary stacking plate 6 are placed in the stacking area; the grabbing claw 4 returns to the top of the belt conveyor 5 for grabbing operation; the longitudinal component 2 and the transverse component 3 are both electric slide rails, and the belt conveyor 5 is used to transport packaging bags.

[0040] Secondly, the first lifting component 9 is disposed at the output end of the transverse component 3. The output end of the first lifting component 9 is fixedly connected to the bracket 10. The rotating component 11 is disposed inside the bracket 10. The output end of the rotating component 11 passes through the bracket 10 and is fixedly connected to the rotating frame 12. The first lifting component 9 is a self-locking cylinder, and the rotating component 11 is a self-locking motor. When the first lifting component 9 is activated, it drives the bracket 10 to move up and down, thereby adjusting the height of the grabbing shell 13 and the storage shell 14. At the same time, when the rotating component 11 is activated, it drives the rotating frame 12 to rotate, thereby adjusting the angle of the grabbing shell 13 so that it is better aligned with the packaging bag.

[0041] At the same time, the grabbing housing 13 and the storage housing 14 are both disposed below the rotating frame 12. The grabbing housing 13 and the storage housing 14 are in communication. Two pushing components 15 are sequentially disposed on the inner top wall of the grabbing housing 13. The output ends of the two pushing components 15 are both fixedly connected to the pushing plate 8. The two sliding support units are symmetrically disposed within the grabbing housing 13. The grabbing claw 4 grabs the packaging bag into the grabbing housing 13. At this time, the sliding support unit is activated and positioned below the packaging bag. The grabbing claw 4 then releases its grip and places the packaging bag on the sliding support unit, thereby activating the pushing component 15, driving the pushing plate 8 to move and push the packaging bag into the storage housing 14 for temporary palletizing. The pushing component 15 is a cylinder.

[0042] In addition, the electric suction cup 16 is disposed on the inner top wall of the U-shaped plate 19. The second lifting component 18 is disposed above the gripping housing 13. The output end of the second lifting component 18 passes through the gripping housing 13 and is fixedly connected to the U-shaped plate 19.

The output ends of the two clamping components 20 are respectively fixedly connected to corresponding clamping plates 21. Multiple first infrared sensors 17 are sequentially disposed below the U-shaped plate 19. The first infrared sensors 17 can be used to scan and identify packaging bags on the belt conveyor 5, facilitating better positioning of the gripping claw 4 and improving gripping accuracy. The second lifting component 18 is a self-locking cylinder. When activated, it drives the U-shaped plate 19 downward, positioning the packaging bag within the U-shaped plate 19. First, the electric suction cup 16 is activated to absorb the upper portion of the packaging bag. Then, the clamping component 20 is activated to move the clamping plate 21 to clamp the packaging bag. The clamping component 20 is a self-locking cylinder.

[0043] Then, the plurality of side telescopic components 22 are sequentially arranged on the inner side wall of the grabbing housing 13, the output ends of the plurality of side telescopic components 22 are fixedly connected to the support plate 23, and the plurality of first rollers 24 are sequentially arranged on the support plate 23. The plurality of side telescopic components 22 are self-locking cylinders. First, the packaging bag is grabbed and brought into the grabbing housing 13. At this time, the side telescopic components 22 are activated, driving the support plate 23 to extend and be located below the U-shaped plate 19 and the packaging bag. At this time, the clamping plate 21 is released, and the packaging bag falls onto the support plate 23 and contacts the plurality of first rollers 24. Then, the pushing plate 8 pushes the packaging bag into the storage housing 14 and is stacked on the temporary stacking plate 6.

[0044] Again, the second infrared sensor 25 is arranged on the inner side wall of the storage shell 14, multiple second rollers 26 are arranged in sequence on the temporary stacking plate 6, and the ejection unit is arranged on the temporary stacking plate 6; the two ejection components 27 are arranged in sequence on the temporary stacking plate 6 and are located on one side of the second roller 26, the output ends of the two ejection components 27 are fixedly connected to the ejection plate 28, and the clamping mechanism is arranged on the ejection plate 28. When the packaging bag is located on the temporary stacking plate 6, the second infrared sensor 25 can detect that there is an object above the temporary stacking plate 6. This object occupies the normal stacking of the next packaging bag. At this time, the lifting screw machine 7 can be started to drive the temporary stacking plate 6 to move downward. When the second infrared sensor 25 no longer detects the object, it can stop moving downward, thereby continuing to grab subsequent packaging bags; the pushing component 27 is a self-locking cylinder. When the pushing component 27 is started, it drives the pushing plate 28 to move, and then it is located at one end of the packaging bag above the temporary stacking plate 6, playing a limiting role to prevent the overlapping packaging bags from tilting or offsetting. At this time, the clamping mechanism is started again to clamp the packaging bag to prevent loosening and improve the stacking quality.

[0045] Furthermore, the two moving parts 29 are sequentially arranged on one side of the ejection plate 28, the side clamping plates 30 are arranged at the output ends of the two moving parts 29, the top support plate 31 is arranged above the side clamping plates 21, and the pressing part 32 is arranged above the top support plate 31. The output end of the pressing part 32 passes through the top support plate 31 and is fixedly connected to the top clamping plate 33. The moving parts 29 are screw machines, and the pressing part 32 is a self-locking electric push rod. After temporary palletizing is completed, the moving parts 29 are activated, driving the side clamping plates 30 to move, thereby holding the packaging bags from one side. At the same time, the top support plate 31 supports the pressing part 32. When the pressing part 32 is activated, it presses and clamps the temporarily palletized packaging bags from top to bottom through the top clamping plate 33, thereby moving the storage housing 14 to the palletizing area and removing the temporarily palletized packaging bags. This can prevent the temporarily palletized packaging bags from loosening during transportation.

The opening and closing component 35 is an electric slide rail. The door panel 34 opens and closes the storage housing 14. When the opening and closing component 35 is activated, the door panel 34 is opened through the connection of the connecting block 36. At this time, the pushing component 27 is activated, driving the pushing plate 28 to move. At the same time, the bottom of the temporarily stacked packaging bags contacts the multiple second rollers 26, and they are then smoothly pushed out of the storage housing 14.

[0047] When using a grabbing and stacking device for packaging bags of the present embodiment, the packaging bags are placed on the belt conveyor 5 for transportation, and stop after moving to the bottom of the grabbing claw 4; the first lifting component 9 is started to drive the bracket 10 to move up and down, thereby adjusting the height of the grabbing shell 13 and the storage shell 14, and at the same time the rotating component 11 is started to drive the rotating frame 12 to rotate, and the angle of the grabbing shell 13 can be adjusted to better align it with the packaging bag; then the second lifting component 18 is started to drive the U-shaped plate 19 to move downward, so that the packaging bag is located inside the U-shaped plate 19, and first the electric suction cup 16 is started to suck the upper part of the packaging bag. Attached, then the clamping component 20 is started, driving the clamping plate 21 to move, clamping the packaging bag and putting it into the grabbing shell 13; at this time, the side telescopic component 22 is started, driving the support plate 23 to extend, and is located under the U-shaped plate 19 and the packaging bag, at this time the clamping plate 21 is loosened, and the packaging bag falls on the support plate 23 and contacts the multiple first rollers 24, and then the pushing plate 8 pushes the packaging bag into the storage shell 14 and is stacked on the temporary stacking plate 6; after placing a packaging bag, the second infrared sensor 25 can detect that there is an object above the temporary stacking plate 6, and this object occupies the next bag The bags are stacked normally. At this time, the lifting screw machine 7 can be started to drive the temporary stacking plate 6 to move downward. When the second infrared sensor 25 no longer detects an object, it can stop moving downward, thereby continuing to grab the subsequent packaging bags; the pushing component 27 is a self-locking cylinder. When the pushing component 27 is started, it drives the pushing plate 28 to move, and then it is located at one end of the packaging bag above the temporary stacking plate 6, playing a limiting role to prevent the overlapping packaging bags from tilting or offsetting. At this time, the clamping mechanism is started again to clamp the packaging bag to prevent loosening and improve the stacking quality; thereby gradually overlapping multiple packaging bags and completing temporary stacking above the belt conveyor 5 without going back and forth Palletizing area; finally, after the temporary palletizing is completed, the moving component 29 is started, driving the side clamping plate 30 to move, thereby holding the packaging bag from one side, and at the same time the top support plate 31 supports the pressing component 32, and the pressing component 32 is started to press and clamp the temporarily palletized packaging bag from top to bottom through the top clamping plate 33, thereby moving the storage shell 14 to the palletizing area, and taking out the temporarily palletized packaging bag, thereby preventing the temporary palletized packaging bag from loosening during transportation; the longitudinal component 2 and the transverse component 3 drive the entire storage assembly to move to the area on both sides of the belt conveyor 5 for palletizing;The opening and closing component 35 is activated, and the door panel 34 is opened through the connection of the connecting block 36. At this time, the pushing component 27 is activated, driving the pushing plate 28 to move.

All the packaging bags on the temporary stacking plate 6 are placed in the stacking area. The grabbing claw 4 returns to the top of the belt conveyor 5 to perform the grabbing operation.

[0048] Through the above-mentioned structural setting, the packaging bags are first temporarily stacked on the temporary stacking plate 6.
