An avoidance conveying device and an avoidance conveying method are provided. The device includes a receiving device, a front lifting device, a transition device, a rear lifting device, and a sending device arranged in sequence along a direction of conveying glass sheets; the receiving device receives the glass sheets conveyed by a front roller conveyor of an original sheet production line; the sending device conveys the glass sheets to a rear roller conveyor of the original sheet production line; an avoidance channel is formed between the front lifting device and the rear lifting device. Pedestrians and forklifts directly pass through the glass production line at any time through the avoidance channel, shortening the travel distance and the travel duration of pedestrians and forklifts. The glass sheets are finally conveyed to the rear roller conveyor by bypassing the avoidance channel, which ensures continuous and uninterrupted transportation of the glass sheets.
