Description

Technical Field

[0001] This utility model relates to the field of plastic bag production technology, specifically to a plastic bag collection device. Background Technology

[0002] In the plastic bag production process, the collection and palletizing stage after cutting or printing has long relied on manual operation. Workers need to manually sort the scattered plastic bags and stack them into piles. However, the speed of manual operation is limited by physiological conditions and it is difficult to match the high-speed operation rhythm of the production line, which can easily cause production stagnation and low overall efficiency. At the same time, with the continuous rise in labor costs, long-term reliance on manual collection will significantly increase the company's production costs and weaken the product's market competitiveness. The limitations of manual collection have become a prominent problem restricting production.

[0003] To address the drawbacks of manual collection, some companies have introduced robotic arms to replace manual labor for collection and palletizing. However, the operation of robotic arms requires complex programming and debugging, demands high technical skills from operators, and is cumbersome to adjust and adapt to plastic bags of different sizes and materials, resulting in poor flexibility. Furthermore, the purchase cost of robotic arms is high, placing a significant burden on small and medium-sized enterprises with the initial investment. In addition, their precision structure is prone to failure during high-frequency operations, requiring professional personnel for maintenance and incurring high component costs, leading to persistently high maintenance costs. This makes it difficult for robotic arms to be widely adopted in plastic bag collection scenarios. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This embodiment of a plastic bag collection device includes an operating table 1 and a conveying device 2 installed on the operating table 1. The conveying device 2 is used to move and convey a tray carrying plastic bags after cutting or printing. A transfer assembly is also installed on the operating table 1. A suction cup device 19 is installed on the moving end of the transfer assembly. The transfer assembly is used to drive the suction cup device 19 to move, thereby adsorbing and transferring the plastic bags. A side frame 11 is also fixed on the operating table 1 in front of the conveying device 2. Four side plates 16 are fixed on the top of the side frame 11. The side plates 16 are L-shaped, and a placement area is formed between the four side plates 16. It is used for stacking and palletizing plastic bags. A lifting component is installed on the side frame 11. The lifting end of the lifting component is fixed with an upper moving plate 15 located in the placement area. The lifting component can adjust the height of the upper moving plate 15 so that the upper moving plate can move to the optimal position to receive the plastic bags. It also moves down gradually so that the top is always in the optimal placement position, which facilitates the stacking of plastic bags. The bottom of the operating table 1 is fixed with a base plate 6 located below the conveying device 2. A limit component is installed on the base plate 6 to position the tray carrying the plastic bags during the conveying process, so that it is in a designated position for easy suction cup adsorption.

[0020] like Figure 4 The transfer assembly includes a side frame 20 fixed to the operating table 1 and spanning above the conveying device 2. A linear module 17 is mounted on the side frame 20. The moving end of the linear module 17 is fixed with a push cylinder 18 connected to the suction cup device 19. The linear module 17 can drive the suction cup device 19 to move horizontally between the placement area of ​​the conveying device 2 and the side frame 11. The push cylinder 18 can push the suction cup device 19 to move up and down, making it convenient to pick up and place plastic bags.

[0021] The lifting assembly includes a screw device 12 installed inside the side frame 11. The screw of the screw device 12 is threadedly connected to a lifting plate 13 located inside the side frame 11. Four sets of guide rods 14 extending into the placement area are fixed to the top of the lifting plate 13. The tops of the guide rods 14 are fixed to the upper moving plate 15. When the screw device 12 is working, it drives the lifting plate 13 to move up and down. The guide rods 14 drive the upper moving plate 15 to move up and down synchronously, thereby adjusting the stacking height in the placement area.

[0022] like Figure 3The limiting component includes a push cylinder 9 fixed to the top of the base plate 6. The piston rod of the push cylinder 9 is fixed with a baffle 10. The push cylinder 9 can push the baffle 10 to extend and retract, limiting the disc on the conveying device 2 so that the plastic bag stays at the designated position.

[0023] The bottom plate 6 is also equipped with an upper lifting cylinder 7. The piston rod of the upper lifting cylinder 7 is fixed to the upper lifting plate 8. The upper lifting cylinder 7 can push the upper lifting plate 8 to rise, and cooperate with the conveying device 2 to lift the plastic bag to a suitable height, so that the suction cup device 19 can pick it up and prevent the plate from moving.

[0024] like Figure 2 A cover plate 3 is fixed on the conveyor device 2. The bottom of the cover plate 3 is a certain distance away from the belt end of the conveyor device 2 so as not to obstruct the conveying of the disc. A frame 4 is fixed on the inner side of the cover plate 3. The frame 4 is square. Two sets of buffers 5 opposite to the upper top plate 8 are installed on the bottom of the short side of the frame 4. When the disc is lifted by the upper top cylinder 7, the buffer 5 can buffer the disc and press the plastic bag tightly to avoid deviation. After the suction cup device has adsorbed the plastic bag on the disc, the upper top cylinder 7 retracts and then the transfer device removes the plastic bag.

[0025] Two sets of push cylinders 51 opposite to the baffle 10 are installed on the left side of the frame 4. When the disc is lifted by the upper top plate, the push cylinder 51 pushes the disc and retracts when the disc is aligned with the piston rod of the push cylinder. This works in conjunction with the baffle 10 to correct the disc. Then the upper top plate continues to move upward and buffers the shock absorber.

[0026] The working principle of the above embodiments is as follows:

[0027] After slitting or printing, the plastic bags are placed on a tray and conveyed by a conveyor. During conveying, the push cylinder pushes the baffle to lift and limit the tray, positioning it in the designated position. Simultaneously, the upper push cylinder pushes the upper plate upward, lifting the tray to align with the push cylinder. The push cylinder extends and then retracts, working with the baffle to complete the alignment. The upper push cylinder continues to push upward until the upper plate and buffer collide, compressing the plastic bag and achieving precise positioning. The linear module then moves the lower push cylinder and suction cup device onto the plastic bag. The downward-pushing cylinder pushes the suction cup device down to pick up the plastic bag. At this time, the upward-pushing cylinder retracts, and then the downward-pushing cylinder retracts. The linear module drives the suction cup device to move above the placement area of ​​the side frame. The downward-pushing cylinder pushes the suction cup device down again to place the plastic bag on the upward-moving plate. The side plate limits the plastic bag from the side, completing one placement. As the plastic bags are continuously stacked, the screw device drives the lifting plate, guide rod and upward-moving plate to gradually descend, so that the plastic bags placed each time can be neatly stacked until the set number of stacks is completed.

[0028] The entire process is automated, requiring no human intervention, and is highly efficient and stable.

[0029] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
