Abstract

Abstract A method and apparatus for assembling bricks in layers or flats for stacking on a kiln car or the like wherein bricks of different sizes can be assembled in transverse rows that are spaced at various distances from one another by first moving the bricks in longitudinal rows on a feed belt against a stop which compacts them together longitudinally of the feed belt and at the same time aligns them into the transverse rows, which are then moved onto a transfer belt by automatically programming the starts and stops of the feed belt as the transfer belt is run continuously during the assembly of the layer, so that each row is moved onto the transfer belt and then moved a predetermined distance to space it the required amount from the next row on the feed belt while the latter is momentarily stopped. The invention also includes a method and means for forming oblong stacks by feeding different numbers of longitudinal rows for alternate layers of the stack, the number of longitudinal rows for alternate layers of the stack, the number of longitudinal rows for alternate layers of the stack, the number of longitudinal rows for one layer corresponding to the length of the stack and the number of longitudinal rows for the alternate layer corresponding to the width of the stack.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 204 words
A method of stacking bricks which comprises the steps of moving a plurality of adjacenT longitudinal rows of brick onto a feed belt, aligning the bricks in transverse rows by moving said longitudinal rows lengthwise against a fence, thereupon raising said fence and starting said feed belt in order to move a first of said transverse rows onto a transfer belt while running said transfer belt in the same direction as, and at substantially the same speed as, said feed belt, stopping said feed belt for a predetermined length of time when said first transverse row is disposed on said transfer belt while continuing to run said transfer belt such that said first transverse row is spaced a predetermined distance from the next transverse row on said feed belt, and sequentially starting and stopping said feed belt in timed relation with the speed of said transfer belt in order to form a layer of said transverse rows on said transfer belt with said transverse rows spaced at predetermined distances from each other, and thereafter gripping the ends of said transverse rows while maintaining the spacing between them in order to lift them as a layer, and then depositing said layer at a stacking station.
