Abstract
Description
Technical Field
[0001] This utility model relates to a woven bag processing equipment, and more particularly to a woven bag stacking mechanism. Background Technology
[0002] After production and processing, woven bags are bundled by a packing machine, and then stacked neatly and stably for storage, transportation, and subsequent processing. With technological advancements, palletizing has been replaced by machinery. Existing palletizing machines use robotic arms and end-effectors to pick up bundles of woven bags and accurately place them in designated positions according to pre-set parameters, achieving automated palletizing.
[0003] Existing palletizing mechanisms mainly consist of a boom, two gripper arms rotatably mounted on the boom, several gripper fingers mounted on each gripper arm, and a drive assembly for driving the movement of the two gripper arms. When a company's production needs change, such as needing to grip woven bags of different sizes, materials, or weights, the gripper fingers need to be replaced to better meet diverse gripping requirements and ensure gripping stability. However, the existing gripper fingers are fixed to the gripper arms with fasteners, requiring individual operation during disassembly and assembly. This disassembly and assembly method not only involves a large amount of manual labor but also affects the production efficiency of woven bags to some extent. Utility Model Content
[0004] The purpose of this invention is to provide a woven bag palletizing mechanism that enables convenient assembly and disassembly of the claws, thereby reducing manual labor and increasing the production efficiency of woven bags.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a woven bag stacking mechanism, including a boom, two claw arms rotatably mounted on the boom via a rotating shaft, a plurality of claw fingers respectively mounted on each claw arm, and a driving component for driving the two claw arms to move. Each claw finger is provided with a mating structure between it and the claw arm. The mating structure has a mating state and a disengaged state. A fixing plate is detachably fixedly mounted on each claw arm. A limiting structure is formed between the fixing plate and each claw finger to limit the mating structure to be in the mating state.
[0006] By adopting the above technical solution, when replacing the claw fingers, the fixing plate fixed to the claw arm can be removed, thus releasing the limiting structure from restricting the mating structure. This allows the mating structure to be switched from the mating state to the disassembly state, enabling convenient assembly and disassembly of the claw fingers and claw arm. Removing the fixing plate releases the fixing of all claw fingers, significantly reducing the amount of manual operation required for assembling and disassembling claw fingers, thereby increasing the production efficiency of woven bags.
[0007] The further configuration includes a slot disposed on the claw arm and a strip disposed on the claw finger for insertion into the slot. When the strip is inserted into the slot, the movement of the claw finger is restricted in a direction perpendicular to the insertion direction.
[0008] By adopting the above technical solution, the insert is inserted into the slot to form a horizontal limit for both the claw arm and the claw finger, thereby cooperating with other methods to achieve the installation and fixation of the claw finger.
[0009] The limiting structure is further configured such that: the limiting part is disposed on the fixed plate and the limiting groove is disposed on each claw finger and into which the limiting part is inserted; when the limiting part is inserted into the limiting groove, the claw finger is restricted from moving along the length direction of the groove.
[0010] By adopting the above technical solution, the limiting part is inserted into the limiting groove to form a vertical limiting between the claw arm and the claw finger, thereby cooperating with other components to achieve the installation and fixation of the claw finger.
[0011] Further configuration: the opening of the limiting groove is arranged facing the opposite slot side, the fixing plate and the limiting part are fixedly connected by a connecting part, adjacent limiting parts are integrally connected to form an elongated shape, a reinforcing rib is connected between the limiting part and the fixing plate, and several reinforcing ribs are arranged along the length direction of the limiting part.
[0012] By adopting the above technical solution, the reinforcement ribs are set to improve the structural strength of the limiting part, so as to prevent the limiting part from deforming and to better bear the force exerted on it by the claw fingers.
[0013] The further configuration is as follows: the fixing plate and the claw arm are connected by bolt threads, and the number of bolts on each fixing plate is set to at least two.
[0014] By adopting the above technical solution, the fixing plate and the claw arm can be detachably fixed through a bolt structure.
[0015] The drive component is further configured to include gears mounted on two rotating shafts, racks slidably disposed on the boom and meshing with the two gears, and a drive assembly for driving the two racks to move synchronously toward or away from each other.
[0016] By adopting the above technical solution, the drive component drives two racks to move synchronously in opposite directions or back to back, and then cooperates with the rack and gear structure to control the two claw arms to perform actions. This configuration structure makes the claw arms have a wider range of motion.
[0017] The drive assembly is further configured such that: the drive assembly includes a dual-axis motor and screws fixedly mounted on the dual-axis motor and threadedly connected to two racks respectively, wherein the helical patterns on the two screws are reverse threads.
[0018] By adopting the above technical solution, a dual-axis motor drives two screws to rotate, and the two racks are controlled by a reverse thread structure to achieve reciprocating motion in opposite directions.
[0019] In summary, this utility model has the following beneficial effects: it enables convenient assembly and disassembly of the claw fingers, thereby reducing manual operation and increasing the production efficiency of woven bags. Attached Figure Description
