1. A system for taking out items wrapped in a packaging film and accommodated in a packaging box with an open top, comprising:
a first conveyor configured to transfer a packaging box accommodating items therein;
a fixing means for fixing, at a withdrawal position where the items are taken out of the packaging box, the packaging box transferred by the first conveyor with its top open;
a withdrawal means for moving to a space in which the items are accommodated in the packaging box so as to suck and take out the items;
an item transfer means for transferring the items taken out by the withdrawal means with the items placed on the item transfer means; and
a box transfer means for transferring an empty packaging box from which the items are taken out;
wherein, the items are stacked to form a cylinder as a whole, and are arranged in the packaging box such that the cylinder of stacked items has an axis parallel to a direction transferred by the first conveyor;
wherein the withdrawal means is provided with a concave arc-shaped suction surface having a diameter corresponding to the diameter of each item, and the suction surface is provided with a through-hole in communication with an external vacuum source for suctioning the packaging film of the item by vacuum;
wherein, the item has both longitudinal ends having different diameters;
wherein the withdrawal means is provided with a sensor configured to detect the diameter of one end of the item;
wherein, the item transfer means comprises a third conveyor, on which the item taken out by the withdrawal means is placed and transferred, and a rotating device on which the item taken out by the withdrawal means are placed and rotated by 180 degrees; and
when the diameter of one end of the item detected by the sensor is different from the diameter of one end of another item, the withdrawal means loads the associated item onto the rotating device, and sucks and loads the associated item onto the third conveyor after the rotating device rotates.
