A sorting system for an absorbent product which is provided with: a main conveyor path; a branch conveyor path which is branched from the main conveyor path; a main conveyor mechanism which is configured to convey an absorbent product along the main conveyor path; a sorting mechanism which is configured to divert an absorbent product in the main conveyor path from the main conveyor path to the branch conveyor path; and a branch conveyor mechanism which is configured to convey an absorbent product which was diverted by the sorting mechanism along the branch conveyor path wherein the sorting mechanism is provided with a sorting member (8A, 8B) which is configured to divert the absorbent product, and wherein the sorting member (8A, 8B) is configured to be held in a stand-by position outside the main conveyor path when said absorbent product should move along the main conveyor path and is moved, without being stopped, from said standby position outside the main conveyor path to the inside of the main conveyor path and is configured to divert the absorbent product from the main conveyor path to the branch conveyor path and is configured to be then retracted from the main conveyor path and is returned to the standby position, wherein the sorting member (8A, 8B) is configured to be rotated in one direction so as to leave the standby position, cut across the main conveyor path, and return to the standby position, characterised in that the rotation operation of the sorting member (8A, 8B) is started so that the front ends of the absorbent products strike the leading end parts (8AE, 8BE) of the sorting member (8A, 8B). a main conveyor path; a branch conveyor path which is branched from the main conveyor path; a main conveyor mechanism which is configured to convey an absorbent product along the main conveyor path; a sorting mechanism which is configured to divert an absorbent product in the main conveyor path from the main conveyor path to the branch conveyor path; and a branch conveyor mechanism which is configured to convey an absorbent product which was diverted by the sorting mechanism along the branch conveyor path wherein the sorting mechanism is provided with a sorting member (8A, 8B) which is configured to divert the absorbent product, and wherein the sorting member (8A, 8B) is configured to be held in a stand-by position outside the main conveyor path when said absorbent product should move along the main conveyor path and is moved, without being stopped, from said standby position outside the main conveyor path to the inside of the main conveyor path and is configured to divert the absorbent product from the main conveyor path to the branch conveyor path and is configured to be then retracted from the main conveyor path and is returned to the standby position, wherein the sorting member (8A, 8B) is configured to be rotated in one direction so as to leave the standby position, cut across the main conveyor path, and return to the standby position, characterised in that the rotation operation of the sorting member (8A, 8B) is started so that the front ends of the absorbent products strike the leading end parts (8AE, 8BE) of the sorting member (8A, 8B).
