It is carried into the pattern forming section 8 at step c.

Then, the articles W in the three rows a, b, and c are changed direction as necessary in the pattern forming section 8 on the roller conveyors 11, 12, and 13 in the respective rows a, b, and c. Then, they are transported to the pattern alignment section 9, where they are aligned almost simultaneously, for example,
In the case of the loading pattern of Fig. 5, there are 12 items W as shown in Fig. 2, and in the case of the loading pattern of Fig. 6, there are 1 items W as shown in Fig. 3.
One stage of the loading pattern is formed by zero items W, and the second stopper 16 is raised to prevent subsequent items W from entering the pattern alignment section 9.

When a predetermined number of items W in three rows corresponding to one stage of the loading pattern are arranged in the pattern aligning section 9, the pusher device 21 is operated to move the items W for one stage to the waiting sections 2 on both sides.
Either one of the containers 9 and 30 is sent to the standby section 29 on one side, and this one stage worth of items W is transferred onto a pallet P in the loading section 31 on one side.

Further, when one stage of items W is sent out from the pattern alignment section 9 to the waiting section 29 on one side, the second stopper 16 is lowered, and the subsequent items W are carried into the pattern alignment section 9. The articles W for one stage of the loading pattern are arranged in the pattern alignment part 9, and then the second stopper 16 is raised to prevent the subsequent articles W from entering the pattern alignment part 9.
