Apparatus for producing bricks

Abstract

Abstract APPARATUS FOR CUTTING A CONTINOUS LENGTH OR STAND OF COMPRESSED RAW MATERIAL AS IT COMES FROM AN EXTRUSION PRESS AND THEN STACKING THE BLOCKS OR BRICKS THUS CUT SO THAT THE FACING SIDES OF THE INDIVIDUAL BRICKS LIE IN FULL ENGAGEMENT WITH EACH OTHER FOR PROTECTION FROM DISCOLORATION WHEN THEY FIRED. THE APPARATUS INCLUDES A PAIR OF BELT CONVEYORS DISPOSED IN TANDEM FOR CARRYING THE STRAND OF MATERIAL AS IT COMES FROM THE EXTRUDER AND A CUTTER INTERMEDIATE THESE FIRST TWO CONVEYORS FOR CUTTING THE STRAND INTO SECTIONS. A THIRD CONVEYOR, WHICH MOVES IN THE SAME DIRECTION AS THE FIRST TWO, CARRIES EACH SECTION AGAINST A STOP FROM WHICH IT IS PUSHED LATERALLY THROUGH A CUTTER FRAME THAT DIVIDES IT INTO THE DESIRED NUMBER OF BRICKS TO FORM A ROW OF SUCH BRICKS. A FOURTH CONVEYOR THAT OPERATES INTERMITTENTLY IS DISPOSED AT RIGHT ANGLES TO THE OTHER DOWNSTREAM OF THE CUTTER FRAME TO RECEIVE THE ROWS OF BRICKS AS SUCCESSIVE SECTIONS ARE PUSHED THROUGH THE CUTTER FRAME ONE AFTER ANOTHER,SO THAT THE ROWS OF BRICKS COMING FROM THE CUTTER ARE PUSHED TRANSVERSELY ONTO THE FOURTH CONVEYOR. TWO GROUPS OF ROWS ARE FORMED ON THIS LAST CONVEYOR AND ARE SPACED FROM EACH OTHER SO THAT THE SECOND ONE TO BE FORMED CAN BE INVERTED ONTO THE OTHER BY A TURNOVER DEVICE SUCH THAT THE FACES OF THE BRICKS IN ONE GROUP ARE ACCURATELY ALIGNED IN REGISTRY WITH THOSE OF THE OTHER GROUP. A GRIPPER ASSEMBLY THEN PICKS UP THE DOUBLE-LAYER FLAT OF BRICKS THUS FORMED AND PLACES IT ON A KILN CAR. AS SUCCESSIVE DOUBLE-LAYER FLATS ARE FORMED THEY ARE STACKED ONE ON TOP OF THE OTHER UNTIL A STACK OF THE DESIRED HEIGHT IS BUILT ON THE KILN CAR.
