The first transfer unit 110 and the second transfer unit 130 may each include conveyor rollers 111 and 131 that are rotated by receiving power from a driving motor (not shown). The conveyor rollers 111 and 131 may be connected to a power transmission means such as a chain or a belt, and may be disposed along a direction in which the pallet P is to be transported.

In addition, the reason why the pair of second transfer units 130 are disposed to be spaced apart from each other is to provide a space in which the main discharge unit 150, which will be described later, enters and is disposed. To be described later, the main discharge unit 150 and the auxiliary discharge unit 170 may have a width direction area corresponding to the width of the pallet P. As shown in FIG. Accordingly, the main discharge unit 150 and the auxiliary discharge unit 170 having various widthwise areas corresponding to the pallets P having various widths are selectively used, among which the main discharge unit 150 is It is preferable that the pair of second transfer units 130 be spaced apart from each other to provide a predetermined space so as to enter and dispose.
