At the same time, the hook 27 is lowered by driving the hook lifts 28, 28. When the product 1 approaches the collecting cart 39, the extruder 2
9 operates to drop one end of the row of products 1 onto the accumulation trolley, and then the traveling cart 22 of the other hook 26 moves backward, so that the other end of the row of products 1 is placed on the accumulation trolley. The row of products 1 is thus placed on the stacking trolley 39.

At this time, the front and rear wheels are fixed by using the bogies 44, 44 in order to fix and stop the integrated cart 39 on the rail 38. As a result, the product 1 is placed so that the central portion in the longitudinal direction is located at the central portion of the accumulation trolley 39,
Since the integrated products are balanced, it is possible to prevent a situation in which the load is collapsed when the integrated cart 39 is moved.

Therefore, the hooks 26, 27 are returned to the original positions via the hook elevators 28, 28, and the traveling vehicles 22, 22 are moved to the original positions, and the above-described operation is repeated, thereby accumulating the integrated vehicles. Rows of the same product 1 classified into each of 39 to 43 are placed and accumulated. Then, such a repetitive operation can be automatically controlled by an appropriate controller. The stacking carts 39 to 43 on which a predetermined number of stages are stacked are removed from the rails 3 by removing the bollards 44, 44.
The bundle of products 1 drawn out from the classification and accumulation site 45 along the line 8 and stacked in a rectangular cubic shape is transported by a forklift or the like for shipping.
