Description

Technical Field

[0001] The utility model relates to a bagged material grabbing device. Background Art

[0002] At present, in the cement industry, grain industry and fertilizer industry, most of the bagged materials are stacked in a five-color shape during the palletizing and transportation process (two horizontal and three vertical, alternating up and down). A double-bag gripper is installed at the end of the palletizing robot. Two bags are grabbed at the grabbing roller each time, and then the robot's posture is adjusted on the pallet according to the current stacking position, so that the stack is arranged in a five-color shape.

[0003] When stacking, the existing double-bag gripper needs to consider the gap between two adjacent bags, so the height of the gripper needs to be raised to place the bags during stacking. During this process, the shaking and height of the gripper can easily cause bag compression, and the stacking shape has a large front-to-back deviation and is uneven. In addition, due to the uneven placement, the gripper needs to be constantly adjusted, which makes the robot's movement frequency and path frequent, reducing the stacking efficiency. Therefore, a bagged material gripper device is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to overcome the existing defects and provides a bagged material gripping device with a simple structure, neat stacking shapes and high stacking efficiency.

[0005] The technical solution to achieve the above-mentioned purpose is: a bagged material gripping device, comprising a main frame, a drive assembly and a bag blocking assembly; a clamping claw is slidably connected to each end of the main frame, the drive assembly is connected to the upper end surface of the main frame, and the drive assembly is connected to the two clamping claws; the bag blocking assembly is connected to the lower end surface of the main frame.

[0006] Preferably, both ends of the main frame are connected to slide rails respectively, the clamping claws are connected to a sliding frame, and the sliding frame is slidably connected to the slide rails.

[0007] Preferably, the driving assembly includes a driving cylinder, the driving cylinder is connected to the upper end surface of the main frame, and the output end of the driving cylinder is connected to the sliding frame.

[0008] Preferably, the bag blocking assembly includes two bag baffles, and the two bag baffles are respectively connected to both sides of the lower end surface of the main frame.

[0009] Preferably, there are two driving cylinders, and the output ends of the two driving cylinders are arranged opposite to each other and are each connected to one of the sliding racks.

[0010] Preferably, the two bag baffles are located on the inner sides of the two clamping jaws.

[0011] The beneficial effects of the utility model are as follows: the bag material gripper device has a simple structure, and by arranging material bag baffles on both sides of the lower end surface of the main frame, it prevents the bag material from moving with the grabbing teeth, thereby ensuring the uniformity of the stacking shape, and at the same time cooperates with the main frame above to ensure that during the grabbing process, the bag material will not bulge and deform on one side, thereby making the stacking shape neat; the number of robot movements is reduced, and the time consumption in the process is reduced, thereby improving the stacking efficiency.

[0014] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a bag material gripping device includes a main frame 1, a driving assembly and a bag blocking assembly; a clamping claw 2 is slidably connected to each end of the main frame 1, and the two ends of the main frame 1 are respectively connected to the slide rail 3, the clamping claw 2 is connected to the slide frame 4, and the slide frame 4 is slidably connected to the slide rail 3.

[0017] Specifically, the drive assembly is connected to the upper end of the main frame 1 and to the two clamping jaws 2. The drive assembly includes a drive cylinder 5, which is connected to the upper end of the main frame 1. The output end of the drive cylinder 5 is connected to the sliding frame 4. There are two drive cylinders 5, with the output ends of the two drive cylinders 5 arranged in opposite directions, each connected to a sliding frame 4. The output ends of the two drive cylinders 5 extend or retract simultaneously, driving the two clamping jaws 2 to simultaneously tighten the clamp or release the material.

[0018] Specifically, the bag retaining assembly is connected to the lower end face of the main frame 1. It includes two bag retaining plates 6, one attached to each side of the lower end face of the main frame 1. These plates are located inside the two gripping jaws 2. These plates prevent the bagged material from following the gripping teeth during the gripper's extension and retraction process, ensuring a uniform stack shape. In conjunction with the main frame 1 above, these plates prevent the bagged material from bulging or deforming on one side during the gripping process, resulting in a neatly stacked stack.

[0019] This bag material gripper device is connected to the robot. When the robot moves to the top of the grabbing roller, the output ends of the two driving cylinders 5 extend at the same time, pushing the two sliding frames 4 to slide on the slide rail 3, so that the two clamps 2 open, and the robot moves to the grabbing position. The output ends of the two driving cylinders 5 retract at the same time, driving the two clamps 2 to close and grab the material. Then the robot moves to the stacking point, opens the telescopic gripper, and the single-layer palletizing is completed. Repeat the operation to complete the palletizing of the material. Because the material bag baffles 6 are set on both sides of the lower end face of the main frame 1, during the process of the gripper's extension and retraction, the bagged material is prevented from moving with the grabbing teeth, ensuring the uniformity of the stack shape. Cooperating with the main frame 1 above, it is ensured that during the grabbing process, the bagged material will not bulge and deform on one side, thereby making the stacking shape neat. If the stacking shape is neat, there is no need for the robot to move multiple times to adjust the stack shape, which reduces the number of movements and the time consumption in the process, thereby improving the stacking efficiency.

[0020] The bagged material gripper device has a simple structure. By arranging material bag baffles 6 on both sides of the lower end surface of the main frame 1, the bagged material is prevented from moving with the grabbing teeth, thereby ensuring a uniform stack shape. At the same time, in conjunction with the main frame 1 above, it ensures that during the grabbing process, the bagged material will not bulge or deform on one side, thereby making the stacking shape neat; the number of robot movements is reduced, and the time consumption in the process is reduced, thereby improving the stacking efficiency.

[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
