Three-dimensional conveying device and method for plate glass production line

A three-dimensional conveying device for a plate glass production line, comprising:

• a plate receiving device, arranged at a tail end of an original plate production line, wherein the plate receiving device comprises a plate receiving height-adjustable rail and not fewer than two layers of plate receiving roller beds, wherein adjacent plate receiving roller beds are arranged parallel to each other, each of the plate receiving roller beds is configured to ascend or descend in a height direction of the plate receiving height-adjustable rail, and plate glass is movable in a driving direction of driving components in the plate receiving roller beds;
• a vertical height-adjustable device, comprising a vertical height-adjustable rail and not fewer than two layers of vertical roller beds, wherein the vertical height-adjustable rail is arranged in a vertical direction, adjacent vertical roller beds are arranged parallel to each other, each of the vertical roller beds is configured to ascend or descend in a height direction of the vertical height-adjustable rail, the vertical roller bed is opposite to the plate receiving roller bed, and the plate glass is movable in a horizontal direction of the vertical roller bed;
• and
• a plate sending device, arranged at a head end of a deep processing line or a stacking machine roller bed, wherein the plate sending device is arranged above or below the plate receiving device, and the plate sending device comprises a plate sending height-adjustable rail and not fewer than two layers of plate sending roller beds, wherein adjacent plate sending roller beds are arranged parallel to each other, each of the plate sending roller beds is configured to ascend or descend in a height direction of the plate sending height-adjustable rail, and the plate glass is movable in a driving direction of driving components in the plate sending roller beds;
• wherein the plate receiving device is provided with a plate receiving roller bed zero-position switch configured to position a docked conveying zero position of the plate receiving roller bed relative to the vertical roller bed, the vertical height-adjustable device is provided with a first vertical roller bed zero-position switch and a second vertical roller bed zero-position switch respectively configured to position docked conveying zero positions of the vertical roller beds relative to the plate receiving roller bed and the plate sending roller bed, and the plate sending device is provided with a plate sending roller bed zero-position switch configured to position a docked conveying zero position of the plate sending roller bed relative to the vertical roller bed.
