Description

Technical Field

[0001] The invention belongs to the technical field of logistics and transportation, and in particular relates to a conveying material system for rapidly lifting goods with adjustable positions and uninterrupted grouping. Background Art

[0002] Nowadays, large-scale logistics or storage centers mostly use conveyor lines to transport materials, which are highly efficient and stable. Some production lines need to organize the goods and lift the goods to a specified height to convey the goods to the robot gripper or subsequent production lines. The current logistics and transportation industry has high requirements for efficiency and stability, and it is necessary to develop a conveyor system that can adjust the position of goods, continuously organize and quickly lift the goods. It can realize the rapid and continuous grouping of goods, the adjustment of the position of goods, and the rapid lifting and conveying of goods.

[0003] Technical solutions of the prior art The existing conveyor line ends are mainly used to lift goods using scissor lifts or winch lifts, which are large in size, occupy a large space, and are heavy.

[0004] Disadvantages of existing technology The existing technology mainly has the following problems: Ordinary lift modules are large in size and weight, driven by air cylinders and oil cylinders, and have low lifting speeds. They need to be equipped with hydraulic pump systems and air compressors separately. In addition, the lifting height accuracy of such mechanisms is not high and difficult to control, and the use of oil cylinders is prone to oil pollution. When an ordinary elevator lifts a cargo box, subsequent cargo boxes cannot continue to be transported into the marshalling unit and need to stop transporting and wait for the elevator to finish feeding and return to its position before entering. The overall material transport marshalling rhythm is slow and the efficiency is low.

[0005] Aiming at the operational requirements of realizing continuous and rapid grouping of goods, adjusting the position of goods, and rapidly lifting and transporting goods at the end of the conveyor line, the present invention proposes a conveying material system with adjustable position of goods for uninterrupted grouping and rapid lifting. It mainly solves the problem of completing a specified number of continuous groupings of goods at the end of the conveyor line, automatically adjusting the position of goods, and completing rapid lifting and transport of goods. The lifting height can be automatically controlled and adjusted by the PLC algorithm, and can cooperate with the receiving mechanism such as the manipulator gripper and the conveyor line to transfer goods. During the cargo lifting operation, the subsequent goods can continue to be input into the continuous and rapid grouping, and there is no motion interference with the goods being grouped when descending. It has the characteristics of compact structure, light weight and miniature, high efficiency and stability, and safe and reliable operation. Summary of the invention

A photoelectric sensor is arranged at the entrance of the conveyor roller line.

[0009] Preferably, the one-level and two-level lifting mechanism comprises a base bottom plate, a guide rail seat, a slider, a guide rail, a screw rod, a screw rod support side, a servo motor, a motor mounting seat, a synchronous pulley set, a first-level lifting side plate and a second-level lifting side plate, the base bottom plate is connected to the roller support side plate by bolts, the base bottom plate is connected to the guide rail seat, the guide rail seat is connected to the guide rail, the guide rails are symmetrically arranged, the two ends of the screw rod are inserted into the screw rod fixed side and the screw rod support side and arranged in the middle of the guide rail, the screw rod fixed side and the screw rod support side are connected to the base bottom plate, the servo motor is connected to the motor mounting seat, and the synchronous pulley set is connected to the base bottom plate.
