The invention provides a conveying system for paper packages and a layered stacking device. The layered stacking device comprises an upper mechanism, a lower mechanism and a push mechanism, wherein the upper mechanism extends to a push opening of a conveying device so as to receive at least two paper packages from the conveying device, the at least two paper packages are stacked and are orderly arranged on the upper mechanism, when the lower mechanism is lifted to a first height and approaches to the push opening, the upper mechanism is pulled away from the push opening of the conveying device, the stacked paper packages which fall from the upper mechanism are received by the lower mechanism, and then when the lower mechanism is descended to a second height, the paper packages which are stacked on the lower mechanism are pushed to a feeding mechanism which is arranged beside the lower mechanism by the push mechanism.
