Procedure and machine for automatic laying of bricks on a substrate

摘要

The application disclosed a method and machine for the automatic setting of bricks onto a supporting layer. So far, prefabricated wall panels have been made by setting the bricks manually into a mold equipped with brick compartments and intended for the said panel. A separate mold had to be prepared for each different panel shape. The object of the present invention is to facilitate, speed up and decrease the cost of the setting of bricks. In the machine according to the invention, the method is carried out by feeding into a cassette conveyor (1, 2, 3, 4) a batch of filled cassettes, of which the first is directed to below the brick take-off device (5). When the cassette conveyor is full and the first cassette is under the take-off, the automatic operation of the machine is started. The brick take-off lifts the topmost brick layer from the cassette and lowers it onto a brick conveyor (6), wherefrom the brick rows are directed onto a transverse belt conveyor (8). A rotating wheel (9) has been fitted to receive one brick at a time into a compartment at its periphery and, after rotating half a round, to lower it onto a flight conveyor (10). The flight of the flight conveyor takes the brick fed by the turning device, or remains vacant if the rotating wheel has been programmed not to rotate and not to deliver a brick onto the flight. A full row of bricks is formed on the flight conveyor, and a pushing device (11) pushes the row onto a centering table (12), on which the distances between the bricks are evened out. A pick-up device above lifts the centered bricks, centering them in their longitudinal direction, and lowers them into the mold in one, two or several batches, in accordance with the desired bond, the machine moving forward one step between the lowerings in accordance with the programmed bond. The machine stops at the latest upon the panel being completed and also upon the cassettes having been emptied.
