TECHNICAL FIELD

[0001] The present application relates to a vertical glass semi-finished product conveying and buffering system, belonging to the technical field of glass production devices. BACKGROUND

[0002] Current glass panel production lines are roughly divided into front and rear sections. The front section is mainly responsible for the formation and semi-finished processing of glass panels, while the rear section is mainly responsible for the finishing of semi-finished glass (24) panels and the final output of finished products. A glass semi-finished product buffering device is usually installed at the end of the front production line to prevent the front production line from being affected by the rear production line stopping due to equipment failure or other reasons.

[0003] There are also some devices that can be used for buffering during the glass production process, such as patent CN210973000U: Buffering device for glass conveying device and glass conveying equipment, which mainly solves the buffering of the upper and lower processes. However, the buffering space is limited and is mainly applied to relatively small-scale glass production lines. Patent CN209583027U: Buffering system of automatic glass production line, which has a similar structure to patent CN210973000U and basically the same design principle, is also suitable for relatively small-scale glass production lines. Both patents mainly achieve buffering and do not effectively connect the front and rear processes. Some glass buffering devices currently in use have a large footprint and low space utilization.
