As a key piece of equipment in the field of automated logistics and warehousing, the palletizer can efficiently and precisely stack packaged items on pallets in a preset arrangement, enabling automatic palletizing operations. This greatly improves logistics efficiency and the utilization rate of warehousing space. From traditional mechanical palletizers to advanced robotic palletizers, the technology has been continuously innovated and is widely applied in numerous industries such as food and beverage, chemical, pharmaceutical, and building materials.
Working Principle
Take the common mid-level and low-level palletizers as an example. The working process is as follows: The flat plate carries a layer of workpieces that meet the requirements of the pallet and moves forward to the vertical plane of the pallet. The upper material baffle descends, and the positioning baffles on the other three sides are activated to clamp. The flat plate returns to its original position, and the workpieces drop onto the surface of the pallet. A certain distance (such as 10mm) is maintained between the surface of the pallet and the bottom surface of the flat plate, and the pallet descends by the height of one workpiece. This process is repeated until the stacking on the pallet reaches the set requirements. As for high-level palletizers, the packaged products are usually conveyed through the feeding conveyor. After passing through the flattening machine and the acceleration conveyor, the elevator equipped with the manipulator gripper grabs the products and stacks them on the lifting platform according to the preset stacking pattern. After stacking the specified number of layers, the products are sent out by the pallet conveyor.
Structural Features
Mid-level and low-level palletizers are mainly composed of a flattening conveyor, a buffer stop conveyor, a transfer conveyor, a pallet magazine, a pallet conveyor, a marshalling machine, a bag pushing device, a palletizing device, and a pallet conveyor. The structural design has been optimized, ensuring smooth and reliable operation. No manual intervention is required during normal operation, and it has a wide range of adaptability. In addition, according to different application scenarios and requirements, there are various variant structures of palletizers. For example, the beam structure design of gantry palletizers is suitable for large-span and high-load palletizing. Column-type palletizers, on the other hand, are supported by compact columns, taking up less space and being suitable for working environments with limited space.
