Then, the pallet B on which the container group F is loaded is lifted to a predetermined height by the rotary table 17 and the direction is changed (about 90 degrees).

In the same manner as described above, the remaining bundled body G wound around the container group F is cut and collected, and the cutting unit 6 is returned to the initial position. The group F is transported to the next step (for example, a box making step). Similarly, the pallet B on which the next container group F is loaded is transported to the cutting position a, and the cutting operation of the bound body G is continuously performed.

As described above, the holding plate 5 of the holding arm 59
8 is moved while elastically displacing the locking member 60 provided along the side surface of the container E, even if the container E and the binding body G are in close contact with each other as in the conventional example, the binding body G can be securely held. Can be picked up.

Furthermore, since the bundle G held by the holding plates 57 and 58 is pulled and cut away from the side surface of the container E, the bundle G can be reliably cut without damaging the container E. And the commercial value of the container E can be prevented from being impaired.

Further, when the locking member 60 comes into contact with the side surface of the container E, it is displaced to a state along the side surface of the container E by the reaction force, so that the adjacent or other container E is surely projected to the side portion. And the work of holding another binding body G can be reliably performed.
