[0071] In the slice roller table 1 of the present application, a slice conveying surface is formed.

[0073] The working principle of the device is that the slicing conveying surface of the slicing roller 1 is leveled with the horizontal surface of the main line roller by the upward swinging assembly 4, which plays a role in conveying the glass sheet. According to the information of the glass sheet, the upward swinging assembly 4 is operated when the glass sheet needs to be conveyed to the branch line, the conveying roller transmission assembly 3 is lowered or raised, and when it is lowered, it is leveled with the main line roller and is connected with the lower layer of the double-layer receiving roller 2, and when it is raised, it is inclined upward and is connected with the upper layer of the double-layer receiving roller 2, and finally is operated to the double-layer roller and the turning device to convey the glass sheet to the branch line conveying roller.
