Second Embodiment of the Invention A second embodiment of the present invention will be described with reference to FIG.

In the second embodiment, vertically movable elevator conveyors 1d and 1e according to the present invention are arranged in parallel so that their heights are synchronized and controllable.

FIG. 4 is a front view showing the same time series as FIG. A large veneer having a length of 2400 mm and a width of 1020 mm is placed across the elevating conveyors 1d and 1e (FIG. 4a). Then, the long-sized residential panels 101 are sequentially stacked and placed on this (FIG. 4b). Here, the upper surface of the panel 101 has a lifting device 13d that is interlocked with each other.
By sequentially setting 13 and 13e to be low, the height is always kept substantially constant as indicated by the height A.

Next, the object to be packed is the cross conveyor 2
It is transported to d and 2e. Thereafter, packaging is performed by the same operation as in the first embodiment.

In the second embodiment, when the plate-like members that are long in the lengthwise direction are stacked and packed, the elevating type free roller 21 is used.
Since the conveying direction is changed by using the cross conveyor 2 composed of the drive type rollers 22 orthogonal to it, it has a feature that it is possible to supply the objects to be packed to the packing device without using a wide device in particular. . Therefore, it is preferable to use a cross conveyor for handling long products such as housing materials. The other operations are substantially the same as those in the first embodiment, and thus the description thereof is omitted.

The embodiments and examples of the present invention have been described in detail above with reference to the drawings. However, the specific configuration is not limited to the embodiments and examples, and may be within the scope of the present invention.
