Description
Technical Field
[0001] This utility model relates to the technical field of palletizer gripper equipment, specifically a gripper assembly for a palletizer. Background Technology
[0002] A palletizer, also known as a stacker crane or palletizing machine, is an automated device primarily used to stack products or packaged materials onto pallets or shelves in a specific order and manner. It is commonly used in the final stage of a production line, particularly in industrial production and logistics. Its main function is to automatically transfer materials from conveyor belts to stacking areas, ensuring efficient transportation and storage by piling these items together in a specific way.
[0003] The existing technology has the following defects or problems: The existing technology disclosed in CN210914431U discloses an adjustable spacing palletizer left and right gripper assembly, including a first pneumatic assembly fixed on the left and right mounting plates to drive the gripper to release or grasp, and a top plate. Mounting plates are fixed at both ends of the top plate, and a hanging shaft is fixed between the two mounting plates. Sliding sleeves are fixed on the left and right mounting plates. The left and right gripper assemblies are hung on the hanging shaft through the sliding sleeves, and the left and right gripper assemblies can slide laterally on the hanging shaft. A spacing adjustment cylinder is also provided between the two left and right mounting plates. The spacing adjustment cylinder is a double-headed cylinder, and the piston ends of the two ends of the spacing adjustment cylinder are fixed to the two left and right mounting plates respectively. Driving the spacing adjustment cylinder causes the relative distance between the left and right gripper assemblies to expand or shrink.
[0004] The above-mentioned equipment can accurately and quickly adjust the distance between the left and right gripper components without manual operation during use, and can reliably fix the material bag to the gripper.
[0005] The components mentioned above do not have a structure to adjust the left and right movement of the gripper. If the goods are not in the designated position during the gripping process, they still need to be manually moved to the designated position before being gripped, which is time-consuming and labor-intensive. In addition, the gripping effect is generally poor and the goods are easy to fall. Therefore, a gripper component for a palletizer is proposed to address the above shortcomings.
[0006] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content
