Claims (2)

(57) [Claims] 1. A block group consisting of a set of blocks arranged vertically and horizontally in a fixed direction in the horizontal direction is stacked on a pallet from the top block stage of the block group.
The block rows in the row are sequentially taken out, conveyed from the block row take-out station to the block row transfer station, and transferred onto the intermediate table installed in the block row transfer station, and transferred to the intermediate table. At least one block from the placed block row is taken out sequentially and conveyed to the block arranging station, and the direction of the block is the same as the direction at the time of paving. Block transfer mechanism that sequentially transfers each set of blocks to the alignment panel according to the arrangement mode at the time of pavement construction, and collectively removes the arranged block group arranged on the alignment panel and removes the block group It is transported from the station to the stacking station and stacked on the pallet at the stacking station. Laying device for paving blocks, characterized in that a and click group transport mechanism. 2. The intermediate table is arranged so that each block of the block row transferred on the intermediate table is restricted to one side in a horizontal direction orthogonal to the arrangement direction while restricting the movement of each block. Forming a first ruler surface and a second ruler surface that positions and positions the leading block of the block row on the intermediate table in a direction away from the block adjacent to this block. The block row transfer station has a first pressing member that presses all the blocks of the block row on the intermediate table so that all the blocks come into contact with the first ruler surface, and all the blocks on the intermediate table are the leading blocks. The laying device for the paving block according to claim 1, further comprising a second pressing member that presses the second ruler surface so as to contact the second ruler surface.
