It is possible to effectively prevent the print bundle B on the pallet P from collapsing while being conveyed from the article transfer device 100 to the wrapping device 400. In particular, during the time until the load collapse prevention device 300 is transferred to the wrapping device 400, the pallet P of the load collapse prevention device 300 is held by the pressing plate 322 pressing the printing plate bundle B regardless of the power of the motor 312 by the carriage.
Since it moves in accordance with the above, it is possible to effectively prevent the shift and deformation of the printing plate bundle B.

Furthermore, in the article transfer apparatus 100, when the rotating frame 110 is located at the first position, the pallet take-out mechanism 200T automatically takes out an unnecessary empty pallet P from the pallet receiving section 120, and The pallet P is automatically supplied to the pallet dispensing unit 130 by the pallet supply mechanism 200S when the rotary frame 110 is located at the second position. Therefore, it is possible to efficiently carry the bundle of printed books B without bothering the operator.

The pallet P in which the book bundle B is vertically stacked by the article transfer device 100 is conveyed to the lapping device 400, and the book bundle B on the pallet P is laterally wrapped by the wrapping device 400. The film is bundled and conveyed by the slat conveyor 30 to a bookbinding process or the like. Therefore, it is possible to prevent the deformation of the printed book, and it is possible to effectively prevent the collapse of the load before being conveyed to the bookbinding process or the like.

As described above, according to this embodiment, after stacking the book bundle B on the pallet P in a horizontally stacked state, the pallet P on which the book bundle B is stacked is placed on the conveyor 1
0, 20 to convey to the article transfer device 100 and press the bundle B
Is vertically stacked on another pallet P, and then
The pallet P, in which this bundle of printing books B is vertically stacked, is transferred to the conveyor 20.
