As shown in fig. 17, a =10, b =4, m =18, and n =12 are exemplified. From bottom to top in the direction, the brick row in the third layer that forms fork truck hole A carries out the pile up neatly after the brick row sign indicating number brick of second layer, because the quantity of every row of brick in the third layer is 12, then can carry out the separation of fragment of brick with the brick row that 12 bricks formed, and then form two vacancies in every row of brick. And each vacancy is formed by the thickness of three bricks, so that the size of the forklift hole A is larger than the length of a half brick, and the width requirement of the forklift upper fork plate can be met. Thus, when the forklift is carried, the fork plate can be easily inserted into the forklift hole A by the forklift, and the requirement on the forklift is reduced.

Further, in order to accurately place the number of bricks in the b rows of the brick rows in the one layer of the brick layer forming the forklift hole a when an operator places the bricks on the conveying line, the brick row placing and conveying method further comprises: the conveying line carries out light indication to the row b brick row in the one deck brick layer that is arranged in forming the fork truck hole through the pilot lamp at the in-process that carries the brick row.

Specifically, because operating personnel need arrange the brick to b in the one deck brick layer that forms the forklift hole and arrange the brick of putting a small amount when placing the fragment of brick to the transfer chain, in order to avoid misoperation, then instruct under the condition that n bricks were placed to needs through the pilot lamp, like this, operating personnel is when placing the fragment of brick, when the pilot lamp is bright, then the quantity of every row of brick of reduction that corresponds to accurate placing n bricks.

Preferably, the operator places the bricks on the conveyor line to form a row of bricks, the conveyor line being operated continuously, and the row of bricks having a greater number of bricks, obviously without placing m or n bricks at a time. And in order to ensure that the operator can be accurately instructed to place n bricks so as to improve the operation accuracy, the indicator lights are alternately lighted along with the moving b rows of bricks in the conveying process of the b rows of bricks in one layer of brick layer for forming the forklift holes on the conveying line. Specifically, in the process of placing the b-row brick rows in the one layer of brick layer forming the forklift holes, the lamps indicate that the lamps are alternately lightened along the conveying direction along with the conveying steps of the conveying line, namely in the process of conveying the b-row brick rows in the one layer of brick layer forming the forklift holes, the indicating lamps arranged in the conveying direction of the conveying line are lightened one by one to indicate along with the brick rows in the advancing process of the brick rows positioned at the forefront row; and when the last row of bricks is far away from the indicator lamp at the corresponding position, the indicator lamp at the corresponding position is powered off. Like this, alright in order to ensure b row brick row conveying process in the one deck brick layer that is arranged in forming the fork truck hole to have the light instruction of following, and then satisfy the requirement of the accurate sign indicating of operating personnel. And for the distribution of the indicator lamps, the indicator lamps are at least arranged at the front half part of the conveying line so as to meet the indication requirement of the brick placing station.
