[0002] At present, most granular raw materials are packed in bags and then fed into the equipment. Due to the shape of the raw materials, the shape of the material bags is not fixed, resulting in very troublesome single transfer of the material bags, that is, it is difficult for the manipulator to stably pick up the material bags for transfer, making the feeding efficiency low.

[0003] Referring to a material bag clamp disclosed in a patent document with the publication number CN214878408U, which includes a clamp body, a pressing mechanism and two picking mechanisms. The picking mechanism includes a picking driving part, a picking transmission part and a picking part. The picking driving part is used to drive the picking part to rotate through the picking transmission part. The picking parts of the two picking mechanisms are used to lift the material bag from both sides of the bottom of the material bag. The pressing mechanism is used to press down the material bag lifted by the picking mechanism. When this technical solution is used, it is driven by the picking driving part to drive the picking part to rotate to realize the lifting of the material bag, and after the material bag is lifted, the pressing mechanism presses down and positions the material bag, ensuring a stable picking and clamping effect on the material bag for easy transfer. For the above technical solution, although the stable picking of the material bag is realized, the grasping rod cannot be quickly retracted and positioned during use, which is inconvenient during use.

[0026] See Figure 1 and Figure 3 On the rotating shaft 6, a rotating arm 7 is fixedly installed. On the rotating arm 7, a gripper rod fixing plate 8 is fixedly installed. On the gripper rod fixing plate 8, a gripper rod 9 is fixedly installed. Between the gripper rods 9, a material bag 30 is movably installed. By driving the gripper rod fixing plate 8 and the gripper rod 9 to rotate and tilt synchronously through the rotating arm 7, the movement of the gripper rod 9 completes the secondary clamping and fixing of the material bag 30.

[0027] See Figure 1 、 Figure 2 and Figure 3 One end of the guide post 12 is fixed with a universal bearing fixing plate 14. On the universal bearing fixing plate 14, a cylinder connecting plate 13 is fixed. The cylinder connecting plate 13 is fixedly installed at the bottom of the fixture connecting plate 2. Through the cylinder connecting plate 13, the suction cup fixing bracket 21 is fixedly installed at the bottom of the fixture connecting plate 2.

[0028] See Figure 2 At the bottom of the universal bearing fixing plate 14, a connecting flange shaft 15 is rotatably installed. At the bottom of the connecting flange shaft 15, a polyurethane sleeve 16 is installed. At the bottom of the polyurethane sleeve 16, a flange shaft collar 17 is fixedly installed. At the bottom of the flange shaft collar 17, a spacer ring 18 is installed. At the bottom of the spacer ring 18, a backing plate 20 is installed. Between the backing plate 20 and the spacer ring 18, a universal bearing 19 is installed. Through the universal bearing 19, the suction cup fixing bracket 21 drives the suction cup 29 to rotate, and the rotational movement of the clamping position completes the clamping of the material bag 30.

[0029] See Figure 2 At the bottom of the backing plate 20, a suction cup fixing bracket 21 is fixedly installed. On the suction cup fixing bracket 21, a linear bearing 23 is installed. At the top of the linear bearing 23, a buffer washer 22 is fixedly installed. At the side of the suction cup fixing bracket 21, a baffle 24 is fixedly installed. The baffle 24 is fixedly installed at the side of the universal bearing 19 to shield and protect the position of the universal bearing 19.

[0030] See Figure 1 、 Figure 2 and Figure 3 At the bottom of the suction cup fixing bracket 21, a stainless steel sleeve 25 is fixedly installed. Inside the stainless steel sleeve 25, a buffer shaft 26 is installed. At the side of the buffer shaft 26, an inner stainless steel sleeve 27 is movably installed. At one end of the inner stainless steel sleeve 27, a contact block 28 is fixedly installed. At the bottom of the suction cup fixing bracket 21, a suction cup 29 is fixedly installed.

[0031] The implementation principle of a material bag unpacking and palletizing fixture in an embodiment of the present application is as follows: The device provides the required electrical energy through an external kinetic energy. When using this device, the connecting flange 1 drives the fixture connecting plate 2 to be fixedly installed on the mobile device. When in use, the lifting cylinder 10 is started to push the suction cup fixing bracket 21 downward. While the suction cup fixing bracket 21 moves downward, the suction cup 29 comes into contact with the material bag 30. The inside of the suction cup 29 is evacuated through an external air extraction device, and the suction cup 29 generates suction to adsorb and fix the material bag 30. When the suction cup 29 is in contact with the material bag 30, the contact blocks 28 come into contact with the material bag 30 from the four corners of the material bag 30. The contact blocks 28 move up and down through the buffer shafts 26 to complete the distance adjustment, thereby avoiding damage to the material bag 30 caused by the contact blocks 28. After the contact blocks 28 are in contact with the material bag 30, they provide multi-point support at four positions to avoid the influence caused by the inclination of the material bag 30 on the suction cup 19. While the suction cup 29 adsorbs and fixes, the displacement cylinder drives the rotating arm 6 and the swing arm 7 to rotate and tilt through the connecting plate. The swing arm 7 rotates and tilts to drive the gripper fixing plate 8 and the gripper 9 to move inward and clamp, and the gripper 9 completes the secondary clamping and fixing of the material bag 30, facilitating subsequent palletizing use.

[0032] The advantages of this embodiment are as follows:

[0033] When this device is in use, a universal bearing mechanism and a material detecting mechanism are arranged in the suction cup assembly. When in close contact with the material bag, it can better adapt to the material bag. The hook flipping mechanism is driven by a cylinder, and the cylinder is provided with a quick exhaust valve, which can extend and retract better.

[0034] The contact blocks of this device come into contact with the material bag. After the contact blocks are in contact with the material bag, they provide multi-point support at four positions to avoid the influence caused by the inclination of the material bag on the suction cup.
