The invention relates to an automatic
pallet transfer device and a conveying
system. The automatic
pallet transfer device comprises a first aerial conveying line, a second aerial conveying line, a
pallet with a workpiece, a ground conveying line, an automatic conveying trolley, a first lifter, a second lifter and a transfer device
assembly, one end of the first aerial conveying line is connected with the upper portion of the first lifter, the upper portion of the second lifter is connected with an upper
station of the workpiece, the lower portion of the first lifter is connected with one end of the ground conveying line, the other end of the ground conveying line is connected with the lower portion of the second lifter, the transfer device
assembly crosses over the ground conveying line, and the automatic conveying trolley is respectively connected with the ground conveying line and the transfer device
assembly in a matched manner. The automatic pallet transfer device meets requirements of automatic transfer of the workpiece, safety of an assembly shop is improved, drop risks of the workpiece in the lifting process are effectively reduced, and the
automation degree of a factory is improved.
