[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0026] Example:

[0027] This device replaces the conveyor belt equipment to feed the empty packaging bags. The feeding mechanism is used to cooperate with the robot to maintain the feeding and deliver the materials one by one.

[0028] The main structure includes a feeding mechanism and a grabbing mechanism.

[0029] The feeding mechanism includes a feeding box 1, which is a rectangular box body. The interior of the feeding box 1 is provided with a silo that is adapted to the size of the packaging bag. The top of the silo is provided with an upward-through feeding port 2, and the bottom of the silo is provided with a feeding port. The feeding port 2 and the feeding port are open structures corresponding to the cross-section of the silo, so that the feeding box 1 is a straight cylindrical square tube that passes through from top to bottom. The feeding port is provided with a bottom plate 3 that closes it, and lugs 4 are provided on both sides of the bottom plate 3. Threaded holes are provided on the lugs 4. Bolt seats 5 are provided at the bottom corresponding to the lugs 4 on both sides of the feeding box 1. Fixing bolts are passed through the bolt seats 5 from top to bottom. The fixing bolts are threadedly connected to the threaded holes to tighten and seal the bottom plate 3 at the feeding port position, which is convenient for disassembly and replenishment of packaging bags inside.

[0030] A support plate 6 is provided in the silo, and the shape of the support plate 6 is adapted to the cross-section of the silo. A downwardly extending side plate 7 is provided on the circumference of the support plate 6. The side plate 7 cooperates with the inner wall of the silo to make the up and down sliding of the support plate 6 relative to the silo more stable, without tilting, and the lifting and lowering are smooth.

[0031] Two left and right spring slots 8 are provided at the bottom of the support plate 6 , and reinforcing ribs 9 are provided between the spring slots 8 and the side plates 7 to increase the strength of the support plate 6 and prevent deformation.

[0032] The bottom plate 3 is provided with two spring seats 10 at the position corresponding to the spring groove 8, and a compression spring 11 is installed on the spring seat 10. The top end of the compression spring 11 is connected to the spring groove 8. The compression spring 11 has an elastic force to lift the support plate 6 and the packaging belt upward, thereby maintaining the upward supply of the packaging bag.

[0033] The support plate 6 is used to store stacks of packaging bags for loading and preparing materials.

[0034] A cross frame 12 is provided on both sides of the feeding port 2. The length direction of the cross frame 12 is adapted to the length direction of the feeding port 2. The cross frame 12 is provided near the long side of the feeding port 2. The cross frame 12 extends horizontally and is provided with four pressing shafts equidistantly along its length. A pressing wheel 13 is rotatably sleeved on the pressing shaft. The pressing wheel 13 is a rubber wheel with rounded edges and corners. It will not leave any marks when it comes into contact with the packaging bag, thus ensuring the integrity of the packaging bag. Even if the packaging bag comes into contact with and is pulled by the pressing wheel 13, the movement of the packaging bag can be coordinated by the rotation of the pressing wheel 13. Moreover, since the support plate 6 has an upward tendency to lift the packaging bag, the packaging bag can be effectively pressed upward onto the bottom surface of the pressing wheel 13, and the packaging bag can be well fixed between the support plate 6 and the pressing wheel 13 in cooperation with the pressing wheel 13, maintaining a neat feeding state.

[0035] The feeding port 2 is provided with a horizontal frame 12 on both sides of which are respectively provided with a downwardly concave groove 14, and a fixing frame 16 is provided on both sides of the groove 14. The fixing frame 16 is a long strip bracket vertically arranged and fixed to the outer wall of the feeding box 1, and the fixing frame 16 is penetrated by a strip hole 17 extending vertically up and down. The two sides of the horizontal frame 12 are penetrated by fastening bolts that cooperate with the strip hole 17. The horizontal frame 12 can be fixed to both sides of the feeding port 2 with adjustable height by fastening bolts, which facilitates disassembly, adjustment, maintenance, replacement, etc. And by adjusting the relative height of the horizontal frame 12 relative to the feeding port 2, the relative height of the pressure wheel 13 at the feeding port 2 can be adjusted, so that after the bottom surface of the suction cup contacts the packaging bag on the top surface, the distance between the pressure wheel 13 and the packaging bag is separated when the feeding box 1 continues to move upward.

[0036] The feed box 1 is provided with a vertical plate 18 on both sides, and a lifting guide rail 19 and a lifting screw 20 are installed on the inner end surface of the vertical plate 18. The lifting guide rails 19 are two and are arranged vertically in parallel. The lifting screw 20 is set between the two lifting guide rails 19. The lifting guide rails 19 slide up and down with a slider, and a lifting slide 21 is fixed on the slider. The lifting screw 20 is equipped with a nut, and the nut is fixed on the lifting slide 21. A motor 25 for driving the lifting screw 20 is installed at the bottom of the vertical plate 18.

[0037] Based on the above structure, the material feeding box 1 can have an up and down lifting stroke.

[0038] The gripping mechanism includes a mounting arm 22 installed at one end of the production line, one end of the mounting arm 22 is used to install a motor 25, and the mounting arm 22 itself is installed and fixed based on the production position requirements. The mounting arm 22 extends horizontally, and the other end of the mounting arm 22 is provided with a swing shaft 23, and one end of the swing shaft 23 is provided with a pulley 24. The pulley 24 and the motor 25 drive the swing shaft 23 through a belt transmission. A special-shaped portion 26 is provided on the swing shaft 23, and the special-shaped portion 26 is a shaft rod portion with a square cross-section, which facilitates more stable installation of the component and avoids loosening and vacancies caused by loose circumferential locking.

[0039] The shaped portion 26 of the swing shaft 23 is provided with two parallel suction cup seats 27. The suction cup seats 27 are cylindrical components. An air cavity is provided inside the suction cup seats 27. A suction cup head 28 connected to the air cavity is installed at the bottom of the suction cup seats 27. An air nozzle is provided on the side wall of the suction cup seats 27. The air nozzle is used to connect to a negative pressure air source through an air pipe, thereby generating vacuum suction to suck and grab the packaging bag. The top of the suction cup seats 27 is provided with a cutout 29. The top of the cutout 29 is provided with a stud bolt that penetrates and tightens it. The bottom of the cutout 29 is provided with a square mounting opening that adapts to the shaped portion 26. After the shaped portion 26 penetrates the mounting opening, it is fixed by the stud bolt at the top of the cutout 29. Based on the mounting relationship between the shaped portion 26 and the suction cup seats 27, when the swing shaft 23 rotates, it can accurately and accurately drive the two suction cup seats 27 to swing, realizing the grabbing action.

[0040] A clearance opening 15 is provided on one side of the feeding port 2 close to the suction cup to leave space for swing feeding.

[0041] When the feeding box 1 rises to the top of its lifting stroke, the bottom surface of the suction cup head 28 is located below the pressure wheel 13, and the bottom surface of the suction cup head 28 presses on the top surface of the packaging bag, limiting the highest position of the topmost packaging bag, thereby stopping the follow-up (following the feeding box 1) rising action of the support plate 6, and the feeding box 1 drives the cross frame 12 and the pressure wheel 13 to continue to rise, thereby separating the pressure wheel 13 from the packaging bag, making it easier to extract a piece of packaging when the suction cup flips. The feeding box 1 can be dropped at the same time as the suction cup flips, or it can be dropped after the suction cup flipping action is completed. In order to ensure that the lower packaging bag is not affected after each packaging bag is extracted, the first timing setting is recommended.

[0042] This device replaces the conveyor belt for loading, significantly reducing the linear distance occupied by the conveyor belt, providing no obstruction for workers walking back and forth. The vertical feeding mechanism automatically feeds the packaging bags upward, eliminating the need for manual piece-by-piece loading, saving workstations and improving loading efficiency. Furthermore, loading is mechanically controlled, resulting in higher time interval accuracy and smoother coordination with subsequent production lines.
