Double-layer conveying system

Abstract

The invention discloses a double-layer conveying system. The double-layer conveying system comprises a supporting part and a conveying trolley, and further comprises an elevator part, wherein the supporting part is provided with an upper layer of guide rails and a lower layer of guide rails; a drive part capable of driving the conveying trolley to move along the upper layer of guide rails or the lower layer of guide rails is arranged on the supporting part; a positioning unit capable of positioning the conveying trolley which moves along the upper layer of guide rails on each station is arranged on the supporting part; and the elevator part can be used for switching the conveying trolley between the upper layer of guide rails and the lower layer of guide rails. During working, a workpiece which is needed to be conveyed on a production line is placed onto the conveying trolley, and the drive part drives the conveying trolley to move along the upper layer of guide rails; when the workpiece reaches the corresponding station, the positioning unit is used for positioning and locking the conveying trolley, and the positioning unit is combined with the elevator part for switching the conveying trolley between the upper layer of guide rails and the lower layer of guide rails, so that long-distance, high-speed and high-precision conveying of the industrial manufacturing automatic production line is completed; and with the design, the cost can be reduced, the performances are reliable, the mounting is convenient, and the conveying needs of the industrial automatic production line are met.

Description

technical field [0001] The invention is used in the technical field of industrial automation equipment, and in particular relates to a double-layer conveying system. Background technique [0002] With economic globalization and high production efficiency, global manufacturing is bound to be intelligentized. At the same time, people's living standards are improving and labor costs are increasing. It is bound to be particularly important to develop fully automatic industrial manufacturing. The automatic conveying system is the main artery of the entire industrial production line, and it is a conveying machine that transmits at high speed within a certain distance. At present, for the long-distance transportation of loads, rack and pinion drives, belt conveyors, linear guide rail slider guides, etc. are often used. However, the above driving and guiding methods have higher requirements on the machining accuracy of mechanical parts, equipment installation and debugging. At pre...
