Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , the present utility model provides the following technical solutions: A bagged material unpacking device includes a robot arm 1, a fixture mechanism 2, a material placement rack 3, an unpacking mechanism 4, a climbing ladder 5, a belt conveyor 6, and a collection box 7. The front end of the robot arm 1 is fixedly installed with the fixture mechanism 2. A material placement rack 3 is arranged on the left side of the robot arm 1. A belt conveyor 6 is arranged on the right side of the robot arm 1. A collection box 7 is arranged below the discharge end of the belt conveyor 6. An unpacking mechanism 4 is arranged directly in front of the robot arm 1. A climbing ladder 5 is arranged in front of the unpacking mechanism 4.

[0025] The jig mechanism 2 includes a fixed frame 201, a connecting seat 202, a cylinder 203, a connecting rod 204, a rotating shaft 205, a shaft seat 206, a connecting plate 207, a piercing gripper 208, a connecting member 209, a baffle 2010 and a jaw groove 2011. The connecting seat 202 is fixedly connected to the center of the upper end of the fixed frame 201. Two cylinders 203 are symmetrically and fixedly installed at the lower end of the fixed frame 201. The front ends of the piston rods of the two cylinders 203 are movably connected to the connecting rods 204 respectively, and the connecting rods 204 are fixedly connected to the rotating shafts 205 on the same side respectively.

[0026] Both ends of the rotating shaft 205 are movably installed in the corresponding two shaft seats 206 respectively. Both ends of the rotating shaft 205 are fixedly connected with connecting plates 207, and the lower ends of the two connecting plates 207 are fixedly connected to the piercing gripper 208.

[0027] Connecting members 209 are fixedly connected to the four corners of the fixed frame 201, and the lower ends of the four connecting members 209 are fixedly connected to the baffle 2010. Claw grooves 2011 are symmetrically formed on the baffle 2010.

[0028] The connecting seat 202 at the upper end of the fixed frame 201 is fixedly connected to the front end of the robotic arm 1.

[0029] Through the link transmission mechanism composed of the cylinder 203, the connecting rod 204, the rotating shaft 205, the connecting plate 207 and the piercing gripper 208 of the jig mechanism 2, the grasping of the material bag can be realized. And through the optimized design of the jaw mechanism, the grasping is more firm. During the stage of retracting the material bag, the added baffle 2010 can ensure that the material bag can smoothly disengage from the jaws, and the material bag is not easily hung on the jaws. At the same time, through the connection between the connecting seat 202 and the robotic arm 1, during unpacking, the robotic arm rotates, so that the materials in the material bag fall out completely.

[0030] Please refer to Figure 1 and Figure 4 , the unpacking mechanism 4 includes a vertical frame 401, a cross beam 402, a cross fixing frame 403, an unpacking cutter group 404, an anti - accumulation baffle 405, a hopper 406, a double - rotor crushing valve 407 and a discharge port 408. A cross beam 402 is fixedly connected inside the vertical frame 401. A cross fixing frame 403 is fixedly connected to the top end of the vertical frame 401. An unpacking cutter group 404 is arranged on the cross fixing frame 403, and an anti - accumulation baffle 405 is fixedly connected to the cross bar of the cross fixing frame 403.

[0031] The hopper 406 is arranged below the unpacking cutter group 404. A double - rotor crushing valve 407 is fixedly installed at the lower end of the hopper 406, and a discharge port 408 is arranged at the lower end of the double - rotor crushing valve 407.

[0032] The above unpacking tool set 404 is composed of an intermediate tapered column and blades that can move in four directions. The movement of the four blades in four directions cuts open the material bag for unpacking, so that the material falls into the hopper 406.

[0033] The working principle and usage process of the present utility model: In specific use, the robotic arm 1 moves above the material bag to be grabbed according to the system instructions. The robotic arm 1 automatically changes the angles of each joint to the position to be grabbed, so that the baffle 2010 at the front end of the fixture mechanism 2 presses down to fix the material bag. Then the air cylinder 203 automatically operates to pull the connecting rod 204, and drives the rotating shaft 205 to rotate through the connecting rod 204. The rotation of the rotating shaft 205 drives the piercing gripper 208 to turn downward through the connecting plates 207 fixedly connected at both ends, so that the jaws on the piercing gripper 208 pass through the baffle 2010 and insert into the material bag, thereby grabbing the material bag; then the robotic arm 1 grabs the material bag above the unpacking mechanism 4 according to the preset program, and the intermediate tapered column and the blades in four directions of the unpacking tool set 404 move in four directions respectively to cut open the material bag for unpacking. After unpacking is completed, the robotic arm 1 lifts and rotates the material bag so that the material in the material bag can completely fall; then the robotic arm 1 moves the material bag above the belt conveyor 6, and the air cylinder 203 pushes the connecting rod 204 to drive the piercing gripper 208 on the connecting plate 207 to retract and release the material bag, and the baffle 2010 can ensure that the material bag smoothly detaches from the piercing gripper 208, avoiding the situation that the material bag hangs on the jaws.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
