Dehacking and stacking concrete brick machine or the like is disclosed for automatically removing arrays of brick from a hack and for producing stacks of arrays suitable for packaging. A gripper transfer grips full arrays of brick resting on the kiln car and deposits such arrays on one of two compacting tables. While resting on the tables, the arrays are compacted to ensure lengthwise and lateral abutting alignment of the concrete brick machine in the arrays.
The concrete brick machine are subsequently transferred after compacting directly to a stacking elevator on which the stack is formed. One compacting table is utilized to produce void rows and operates to withdraw compacted arrays from the stacking location so that brick can be removed to produce the required voids. The array with void rows is then returned to the stacking station for transfer to the stacking elevator at appropriate times in the machine cycle.
Such prior art machines tend to encounter wear problems if the concrete brick machine are required to slide along a support system because fired brick are hard and abrasive and will wear away the supporting surface. Further when the brick are handled excessivelythe machinery cost is relatively high and the possibility of brick damage increases.
In the illustrated embodiment a gripper transfer engages the sides of an array of spaced rows of endwise aligned brick resting on a kiln car. The gripper transfer moves the rows laterally until they abut and are gripped. The transfer thentransfers the gripped arrays to the stacking locations where the brick are released either on a setting table or a void row table.
After side compacting of an array on the void forming table to complete the aligning and compacting operation, the side grippers are retracted and the void table is retracted to remove the array resting thereon from the stacking station. Whileretracted and while subsequent cycles utilizing the stacking table are being performed, selected concrete brick machine are removed from the array on the void forming table to produce the required voids.
