Description

Technical Field

[0001] The utility model belongs to the technical field of palletizers, and in particular relates to an end limiting device for a roller conveyor. Background Art

[0002] The palletizer consists of a roller conveyor for conveying and positioning workpieces, a collecting trough for palletizing, and a material transfer rack for transferring workpieces. The use of the roller conveyor will result in a positioning plate being set at one end of the roller conveyor to limit the end of the workpiece and play a positioning role.

[0003] As for the use of steel, steel has the characteristics of being long and heavy, and its impact force is strong. If a fixed limit plate is set, the large impact will be transmitted to the limit plate, affecting its position stability and life, and will also affect the roller frame.

[0004] If a limit plate with a buffer structure is set up, it can block a certain impact force. However, the reset force of the buffer mechanism is limited, and the elastic force of the buffer mechanism itself may not be able to drive the end of the workpiece to the corresponding position, which will affect the subsequent material movement and stacking.

[0005] Therefore, designing an end limit device that is applicable to steel materials, has a buffering function and can be accurately positioned is a problem that needs to be solved by people skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide an end limit device for a roller conveyor, which bears the impact force of the workpiece on the roller conveyor through a buffer seat and performs buffering protection through a spring. After the impact of the workpiece is offset, the end of the workpiece can be adsorbed by an electromagnet to ensure that the two are connected together. The push cylinder pushes the workpiece to the limit distance to control the accuracy of the position of the buffer seat and the workpiece, ensure the position accuracy of the workpiece, facilitate the subsequent grasping and stacking of the palletizer, ensure that the ends of the workpiece are flush after stacking, and reduce the problem of scattering caused by uneven ends of the workpiece.
