Abstract
Description
Technical Field
[0001] This invention relates to a ton bag lifting rope gripper, which belongs to a type of packaging logistics automation equipment. Background Technology
[0002] Ton bags are commonly used for packaging and transporting powders. A single bag can hold a large amount of material, making them suitable for transporting powders in factories.
[0003] Currently, the single-rod lifting structure of ton bags is flat, requiring a lifting hook to attach to the rope before lifting during logistics transport. Currently, other companies manually attach the lifting rope to the hook. However, some powders have special chemical properties, making manual bag attachment dangerous. Furthermore, the ton bags are often quite tall, requiring operators to climb, and suitable climbing equipment is often lacking at the storage sites, posing a safety hazard to manual work. Currently, there are no robotic arms specifically designed for the flexible lifting ropes of ton bags, while automated logistics equipment has a certain need for gripping these ropes. Summary of the Invention
[0004] This invention provides a gripper for lifting ropes of ton bags, solving the problem of gripping the lifting ropes of flexible ton bags.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] The present invention relates to a ton bag lifting rope gripper, characterized in that it includes a pressing part, a hook, a horizontal bidirectional drive, and a vertical drive.
[0007] The hooks are L-shaped and consist of two sets, each located at one end of the bidirectional driver. The bidirectional driver drives the hooks to approach and separate, with the horizontal L-shaped portions of the two hooks facing the center of the bidirectional driver.
[0008] The lower pressure section is set on both sides of the two sets of hooks, one pair on each side, with a spacing between each pair for the ton bag tethering rope to pass through;
[0009] The vertically driven moving end is equipped with the pressing part and the bidirectional driver.
[0010] According to the ton bag lifting rope gripper, each set of hooks is provided with two hooks, and the moving end of the bidirectional driver is provided with a gripper frame. The gripper frame is long and narrow, with a hook at each end, and the two gripper frames are arranged in parallel.
[0011] According to the ton bag lifting rope gripper, the maximum distance between the two hooks when the bidirectional driver drives them to separate is greater than the width of the ton bag lifting rope.
[0012] According to the ton bag lifting rope gripper, it also includes a lower pressure frame, which is perpendicular to the bidirectional drive. The two ends of the lower pressure frame extend to both sides and downwards, and the lower pressure part is provided at the lower end of the extension.
[0013] According to the ton bag lifting rope gripper, the pressing part is a rectangular ring, the rectangular ring is arranged vertically, the two rectangular rings are arranged in parallel and perpendicular to the movement direction of the hook claw.
[0014] The vertical drive is provided with guide mechanisms on both sides. The guide mechanisms include guide sleeves and guide rods. The guide sleeves and the vertical drive are integrally set, and the guide rods are fixed to the moving end of the vertical drive.
[0015] The ton bag lifting rope gripper also includes a robotic arm, and the vertical drive is located at the moving end of the robotic arm.
[0016] According to the ton bag lifting rope gripper, the vertical part of the L-shaped hook is fixed to the bidirectional driver, and the front end of the horizontal part is arc-shaped and smooth.
[0017] According to the ton bag lifting rope gripper, the bidirectional drive is a bidirectional cylinder, and the vertical drive is a unidirectional cylinder.
[0018] The advantages of this invention are: this device can effectively grab the flexible lifting rope of the ton bag; this device has two functional structures, namely grabbing and pressing down the ton bag, which can improve the success rate of single grabbing.
[0019] This device has a high degree of automation and is in line with the development trend of logistics automation.
[0020] This device is small in size and can work in conjunction with existing ton bags to achieve the gripping of the lifting rope. Attached Figure Description

[0026] The specific implementation details of the present invention are described below:
[0027] The present invention relates to a ton bag lifting rope gripper, which is used to grab and lift the ton bag from the bag opening for hoisting and transportation.
[0028] The specific structure of this device includes a pressing part 2, a hook 1, a horizontal bidirectional drive 3, and a vertical drive 4.
[0029] In this device, the hooks 1 are specifically L-shaped and are respectively set at both ends of the bidirectional driver 3. The bidirectional driver 3 drives the hooks 1 to approach and separate, and the horizontal part of the L-shape of the two hooks 1 faces the middle of the bidirectional driver 3.
[0030] The pressing part 2 is set on both sides of the two sets of hooks 1, one pair on each side, and the interval between each pair is used for the ton bag tethering rope 5 to pass through.
[0031] The vertical drive 4 is equipped with the pressing part 2 and the bidirectional driver 3 at its moving end.
[0032] The end has two claws. The moving end of the bidirectional driver 3 is equipped with a gripper frame 6. The gripper frame 6 is long and has a claw 1 at each end. The two gripper frames 6 are arranged in parallel.
[0033] The maximum distance between the two hooks 1 when driven by the bidirectional driver 3 is greater than the width of the ton bag lifting rope. There are two sets of pressing parts in pairs, connected by a pressing frame. The pressing frame is perpendicular to the bidirectional driver 3, and the two ends of the pressing frame extend to the sides and downwards. The pressing parts 2 are set at the lower ends of the extensions. There are a total of four sets.
[0034] Specifically, the pressing part 2 is a rectangular ring, arranged vertically, with two rectangular rings arranged parallel to each other and perpendicular to the direction of movement of the hook 1. This ring structure prevents the ends from protruding from the hook onto the ton bag structure, thus avoiding damage to the ton bag. It achieves efficient pressing.
[0035] In this device, the bidirectional driver 3 and the lower pressure frame are fixed to the moving end of the vertical driver 4. Guide mechanisms are provided on both sides of the vertical driver 4. The guide mechanism includes a guide sleeve 7 and a guide rod 8. The guide sleeve 7 and the vertical driver 4 are integrally set, and the guide rod 8 is fixed to the moving end of the vertical driver 4.
[0036] This device is fixed to the robotic arm, specifically the moving end of the robotic arm equipped with the vertical drive 4. The vertical part of the claw 1 is fixed to the bidirectional drive 3, and the front end of the horizontal part is smoothly curved.
[0037] The bidirectional drive 3 is a bidirectional cylinder, and the vertical drive 4 is a unidirectional cylinder. The cylinders operate at high speeds and have low requirements for the load on the lifting rope, making them suitable for use in various environments.
[0038] The device descends to the position of the lifting rope on the ton bag under vertical drive. The pressing parts at the four corners of the device press down the four outer corners of the lifting rope to a certain height, suspending the lifting rope at a certain height relative to the bag. The two side hooks 1 pass under the lifting rope under the push of the bidirectional cylinder. Then, the vertical drive rises to lift the lifting rope. After being lifted to a certain height, the main hook of the lifting rope engages and catches the lifting rope. The hooks are pushed outward by the bidirectional drive to release the lifting rope, completing the gripping of the ton bag lifting rope.
