Gravity power and free chain system

Abstract

The invention discloses a gravity power and free chain system which comprises a plurality of trolley trays, a lifting mechanism and a double-layer track conveying mechanism, an upper-layer track and a lower-layer track of the double-layer track conveying mechanism are in an inclined state so that the trolley trays can be conveyed from the high side to the low side by means of self-gravity, and the low side end of the lower-layer track and the high side end of the upper-layer track are arranged on the same side; and the lifting mechanism comprises a vertical frame, a supporting table capable of moving up and down on the vertical frame and a supporting table lifting mechanism, the supporting table comprises a tray clamp, a clamp air cylinder and a thrust air cylinder, the lower-layer track is used for temporarily storing trays with workpieces, a stopper is arranged at the lower side end of the lower-layer track, one trolley tray is released by the stopper every time, the released trays with the workpieces enter the tray clamp and are clamped by the clamp air cylinder, and the workpieces on the trays with the workpieces are extracted when the trays with the workpieces are lifted to a second working position along with the supporting table. The system can replace a motor driving type power and free chain system, the workpieces of the trolley trays can be temporarily stored, and accurate release is realized.

Description

technical field [0001] The invention relates to an accumulation chain system, in particular to a gravity accumulation chain system. Background technique [0002] The product chain system is generally used as the workpiece conveying equipment in the body-in-white main line or side body line welding line. [0003] In the prior art, the power and free chain system is driven by motor power and controlled by a program to ensure the normal operation of the equipment. Due to the complex structure of the system and cumbersome process, the input cost is high, and the traditional power and free conveyor gradually cannot meet the production needs. [0004] Therefore, it is necessary to provide a new accumulation chain system to replace the existing motor-driven accumulation chain system. Contents of the invention [0005] The object of the present invention is to provide a gravity accumulation chain system, so that workpieces can be accumulated and conveyed without power and gravity...
