Description

Technical Field

[0001] This invention relates to automated production equipment for cushioning inflatable bags, and particularly to an automated bagging device for producing cushioning inflatable bags. Background Technology

[0002] Inflatable cushioning bags prevent damage from collisions between goods during logistics transportation, and are therefore widely used in the logistics field. Inflatable cushioning bags include single-layer and double-layer bags. The inflatable cushioning bag produced in this invention is a double-layer bag, specifically comprising an inner bag and an outer bag, with the inner bag nested inside the outer bag. Furthermore, an inflation valve is fixed to the inner bag, and an opening matching the inflation valve is provided on the outer bag.

[0003] Currently, the existing production methods for double-layer cushioning air bags still rely on manual operation for bagging. Workers must first open the outer bag, then insert the inner bag inside, and finally push the valve, fixed to the inner bag, through the opening in the outer bag. During bagging, the inner and outer bags must be aligned and kept flat. Therefore, this process is cumbersome and complex for a single worker, resulting in low efficiency. Furthermore, this traditional manual method is labor-intensive and does not align with the principles of automated production workshops.

[0004] For the reasons mentioned above, there is an urgent need to develop an automated bagging device suitable for producing cushioning air bags, in order to further improve the production efficiency of cushioning air bags and reduce labor costs. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to propose an automated bagging device for producing cushioning inflatable bags, which significantly improves work efficiency and reduces labor costs compared to the traditional manual bagging method.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] An automated bagging device for producing cushioned inflatable bags includes an inner bag support platform, an outer bag support platform, and a bagging platform. The inner bag support platform is connected to the right side of the bagging platform, and the outer bag support platform is connected to the front side of the bagging platform. An inner bag gripper mechanism is provided on the left side of the bagging platform. A pair of conveying slots are arranged side by side in the middle of the bagging platform, and an outer bag conveying device is installed in the conveying slots. Frames are installed on the left and right edges of the bagging platform. Outer bag gripper mechanisms are installed on both frames. A bagging valve device is also installed on the left frame. The bagging valve device includes a valve body positioning clip and a positioning clip telescopic arm. The positioning clip telescopic arm is vertically fixed to the frame, and the valve body positioning clip is fixed to the bottom end of the positioning clip telescopic arm. The valve body positioning clip has a V-shaped notch, which is suspended directly above the circular valve opening of the outer bag. When the valve body positioning clip is lowered to its lowest position, both sides of the V-shaped notch are tangent to the edge of the circular valve opening.

[0008] A further preferred technical solution is that the inner bag gripper mechanism includes a slide rail, a slide plate, a support roller, a gripping arm, and a gripper; the slide plate is installed on the slide rail, the support roller is installed at the front end of the slide rail, the gripper is installed at the front end of the gripping arm, the rear part of the gripping arm is fixed on the slide plate, and the front end of the gripping arm rests on the support roller.

[0009] Further optimizing the technical solution, the inner bag gripper mechanism also includes a gripping arm reinforcing rod, one end of which is fixed to the gripping arm, and the other end is fixed to the slide plate; the gripping arm reinforcing rod and the gripping arm form an angle. This design ensures the stability of the gripping arm during repeated extension and retraction, thereby ensuring the operational stability and reliability of the inner bag gripper mechanism.

[0010] Further optimizing the technical solution, when the grab arm retracts to the end point, the valve body positioning card simultaneously descends to the lowest point.

[0011] A further optimized technical solution includes an outer bag conveying device comprising a conveying track, a conveying block, a first gripper, and a second gripper. The conveying track is fixed to the bottom surface of the packing platform, and the conveying block slides back and forth on the conveying track. The first gripper is located at the front end of the conveying block, and the second gripper is located at the rear end of the conveying block. The first gripper is used to transfer the outer bag from the outer bag carrying platform to the packing platform, and the second gripper is used to remove the packed outer bag from the packing platform to the next process platform.

[0012] Further optimizing the technical solution, the outer bag gripper mechanism includes a hydraulic cylinder, a horizontal connecting rod, a first pneumatic suction cup, and a second pneumatic suction cup; the hydraulic cylinder is vertically fixed on the frame, and the bottom of its telescopic rod is fixedly connected to the horizontal connecting rod, driving the horizontal connecting rod to move up and down; the first pneumatic suction cup includes several units and is fixed to the bottom of the horizontal connecting rod; the second pneumatic suction cup includes several units and is fixed below the packaging platform.

[0013] Further optimization of the technical solution involves providing a plurality of suction cup openings on the kit platform, with each suction cup opening corresponding to a second pneumatic suction cup.

[0014] In a further optimized technical solution, the sleeve valve device also includes a brush pressing device, which includes a brush pressing telescopic arm and a short brush; the brush pressing telescopic arm is fixed on the frame, the short brush is vertically suspended on the outer edge of the V-shaped bayonet, and its brush handle is fixed on the brush pressing telescopic arm and moves up and down with the brush pressing telescopic arm.

[0015] In a further preferred technical solution, the brush pressing device also includes a long brush, which is vertically suspended above the edge of the outer bag. Its handle is fixed on the brush pressing telescopic arm and can move up and down synchronously with the short brush along with the brush pressing telescopic arm.

[0016] Further optimizing the technical solution, the left and right sides of the assembly platform are respectively equipped with pressing devices; the pressing device includes a pressing plate and a pressing plate telescopic arm; the pressing plate telescopic arm is fixed on the frame, the pressing plate is fixed at the bottom end of the pressing plate telescopic arm, and can move up and down with the pressing plate telescopic arm.

[0017] The beneficial effects of this invention are: This device can perfectly automate the bagging process, eliminating the need for manual intervention and significantly reducing labor costs while greatly improving bagging efficiency. Furthermore, the device operates stably, ensures accurate valve application, and has low maintenance costs. Attached Figure Description

Detailed Implementation

[0026] The invention will be further described below with reference to the accompanying drawings.

[0027] The overall layout structure of the present invention is as follows Figure 1 As shown, an automated bagging device for producing cushioned inflatable bags includes an inner bag support platform 1, an outer bag support platform 2, a bag fitting platform 3, and an inner bag gripper mechanism 4. Figure 1 The diagram shown is a top view of the device. The inner bag support platform 1 is connected to the right side of the packaging platform 3, the outer bag support platform 2 is connected to the front side of the packaging platform 3, and the inner bag gripper mechanism 4 is located on the left side of the packaging platform 3. An outer bag conveying device 5 is arranged in parallel in the middle of the packaging platform 3.

[0028] According to the above layout structure, when the bagging operation begins, the inner bag is placed on the inner bag support platform 1 and the outer bag is placed on the outer bag support platform 2. The outer bag is first conveyed to the designated installation position on the bagging platform 3 by the outer bag conveying device 5, and then the inner bag is grabbed into the outer bag of the bagging platform 3 by the inner bag gripper mechanism 4.

[0029] The inner bag has a cylindrical valve body that protrudes upwards, while the outer bag has a valve opening that matches the cylindrical valve body. Therefore, the most difficult part of fitting the inner bag into the outer bag is ensuring that the inner bag is accurately grasped to the designated position each time and that the fixed cylindrical valve body passes through the pre-set valve opening on the outer bag, thus accurately completing the bagging process.

[0030] To achieve the aforementioned goal of precise valve fitting, the inventor has provided ingenious design solutions for each mechanism of this device, as follows:

[0031] like Figure 2As shown, the inner bag gripper mechanism 4 includes a slide rail 41, a slide plate 42, a support roller 43, a gripping arm 44, and a gripper 45. The slide plate 42 is mounted on the slide rail 41, the support roller 43 is mounted at the front end of the slide rail 41, and the gripper 45 is mounted at the front end of the gripping arm 44. The rear end of the gripping arm 44 is fixed to the slide plate 42, and the front end of the gripping arm 44 rests on the support roller 43. The gripping arm 44 slides back and forth with the slide plate 42, thereby pulling the inner bag from the inner bag support platform 1 into the outer bag on the packaging platform 3.

[0032] In addition, in order to improve the stability of the gripper arm during multiple extensions and retractions and ensure the operational stability and reliability of the inner bag gripper mechanism, the inner bag gripper mechanism 4 also includes a gripper arm reinforcing rod 46. One end of the gripper arm reinforcing rod 46 is fixed to the gripper arm 44, and the other end is fixed to the slide plate 42. The gripper arm reinforcing rod 46 and the gripper arm 44 form an angle.

[0033] like Figure 3 and 4 As shown, a pair of conveyor slots are arranged side-by-side in the middle of the packaging platform 3, and an outer bag conveying device 5 is installed in the conveyor slots. The outer bag conveying device 5 includes a conveyor track 51, a conveyor block 52, a first gripper 53, and a second gripper 54. The conveyor track 51 is fixed to the bottom surface of the packaging platform 3, and the conveyor block 52 is mounted on the conveyor track 51 and slides back and forth. The first gripper 53 is located at the front end of the conveyor block 52, and the second gripper 54 is located at the rear end of the conveyor block 52. The first gripper 53 is used to clamp and send the outer bag from the outer bag carrying platform 2 to the packaging platform, and the second gripper 54 is used to clamp the bagged outer bag from the packaging platform 3 to the next process platform.

[0034] like Figure 5 and 7 As shown, frames 31 are mounted on the left and right sides of the assembly platform 3, and an outer bag gripper mechanism is provided on the frame 31. The outer bag gripper mechanism includes a hydraulic cylinder 32, a horizontal connecting rod 33, a first pneumatic suction cup 34, and a second pneumatic suction cup 35. The hydraulic cylinder 32 is vertically fixed to the frame 31, and the bottom of its telescopic rod is fixedly connected to the horizontal connecting rod 33, driving the horizontal connecting rod 33 to move up and down. Several first pneumatic suction cups 34 are included and fixed to the bottom of the horizontal connecting rod 33; several second pneumatic suction cups 35 are included and fixed below the assembly platform 3.

[0035] A pressing device is also installed on the left and right sides of the assembly platform 3. The pressing device includes a pressing plate 36 and a pressing plate telescopic arm 37; the pressing plate telescopic arm 37 is fixed on the frame 31, and the pressing plate 36 is fixed to the bottom end of the pressing plate telescopic arm 37 and can move up and down with the pressing plate telescopic arm 37.

[0036] like Figure 6 and 7As shown, a valve mounting device is also installed on the frame 31. This device includes a valve body positioning clip 381 and a positioning clip telescopic arm 382. The positioning clip telescopic arm 382 is vertically fixed to the frame 31, and the valve body positioning clip 381 is fixed to the bottom end of the positioning clip telescopic arm 382. The valve body positioning clip 381 has a V-shaped notch, which faces the valve body mounting position, and both sides of the notch are tangent to the edge of the valve body.

[0037] To ensure that the edge of the outer bag valve body opening can be completely fitted into the bottom of the valve body, the valve fitting device also includes a brush pressing device. The brush pressing device includes a brush pressing telescopic arm 384 and a short brush 383. The brush pressing telescopic arm 384 is fixed on the frame 31, and the short brush 383 is vertically suspended from the outer edge of the V-shaped bayonet. Its brush handle is fixed on the brush pressing telescopic arm 384 and can move up and down with the brush pressing telescopic arm 384.

[0038] In this embodiment, the pressure brush device 384 also includes a long brush 385. The long brush 385 is designed to expel air from the rear edge of the outer bag, making the rear edge of the outer bag easier for the second gripper 54 to hold, thereby enhancing the conveying reliability of the outer bag conveying device 5.

[0039] The long brush 385 is suspended vertically above the edge of the outer bag, and its handle is fixed on the brush pressing telescopic arm 384. It can move up and down synchronously with the short brush 383 along with the brush pressing telescopic arm 384.

[0040] The working principle of this invention is as follows: The inner bag with the valve body fixed is placed on the inner bag support platform 1, and the outer bag with the valve body opening is placed on the outer bag support platform 2; the outer bag conveying device 5 conveys the outer bag from the outer bag support platform 2 to the set platform 3; the outer bag gripper mechanism opens the outer bag through the first pneumatic suction cup 34 and the second pneumatic suction cup 35; the inner bag gripper mechanism 4 grabs the inner bag into the outer bag; when the gripper arm 44 retracts to the end point, the valve body positioning card 381 descends to the lowest point simultaneously. At this time, the V-shaped card slot of the valve body positioning card 381 is just locked on the outer wall of the cylindrical valve body, and the valve body is fitted into the valve body opening of the outer bag. Finally, the outer bag gripper mechanism releases the suction cup, and the short brush 383 and long brush 384 in the pressure brush device press down simultaneously to ensure the reliability of the sleeve valve and squeeze out the gas from the edge of the outer bag, so that the second gripper 54 on the outer bag conveying device 5 can clamp the edge of the outer bag. Then the edge pressing device presses down to squeeze out the air inside the bag body, and finally the outer bag conveying device 5 transports the fitted cushioning air bag to the next process.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this solution. Those skilled in the art should understand that this solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this solution. Various changes and modifications can be made to this solution without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed solution. The scope of protection of this solution is defined by the appended claims and their equivalents.
