Although the switching operation timings of No. 3 are synchronized with each other, in other embodiments, the switching conveyors 13 and 23 may be operated at mutually staggered timings.

FIG. 18 shows an example in which only two types of block-shaped products, white roll paper Ya and red roll paper Yb, are used and packaged in a packaging bag S. In this case, the log switching device 1 side A red long log is placed on one side of each conveyor 2a, 2b of the feeding device 2.
In addition to supplying only the white long logs
7) and the above-mentioned sorting conveyor 16 (or 17) on the other conveyance lane 20 side are the heads of the block-shaped product rows that are supplied in advance to each terminal side of the upward and downward sorting conveyors 27 (or 26). One block-like product (for example, white roll paper 1a) of a different color from the block-like product (for example, red roll paper Yb) is placed. When the production line for bagged block-shaped products is operated in this state, the block-shaped products of different colors are arranged in a staggered manner when viewed from each side in four directions, as shown in Fig. 18. It becomes stuffed.

In this example, the block-shaped products are packaged in four rows each, but the block-shaped products are packed in two rows.
For row-by-row packaging, a series of product transport lanes 1
0 (or 20) using only one lane, and when the block-shaped products are packaged in 6 or more even numbered rows, the product transport lanes 10 (or 20) are arranged in parallel as appropriate. Just go.

In the above embodiments, the case where roll papers of different colors are packaged has been described, but the present invention is applicable not only to roll paper but also to the packaging of other block-shaped products.

(Effects of the Invention) According to the automatic bagging device for block-like products of different colors of the present invention, two rows of block-like products of mutually different colors are packed.
In cases where multiple products are packed in bags in appropriate even number rows such as 4 rows or 6 rows, each block of products adjacent to each other vertically or horizontally is of a different color, and each row has two different colors. Different block-shaped products are alternately arranged one after another and can be automatically packaged one after another in a packaging bag S whose interior can be seen through. Therefore, the design of the packaged block-shaped products It has the effect of improving feelings.
