ABSTRACT:
An oblong block turning apparatus comprises a conveyor pin assembly, a block advance pin assembly, a pivot pin assembly, a flip pin assembly, and an elongated trough with a pair of side walls bridged by a bottom surface. The pin assemblies include respective chains carrying a plurality of respective pins which extend laterally through the trough while moving downstream through the trough. To turn an oblong block deposited into the trough, the block is first pushed downstream through the trough using a conveyor pin of the conveyor pin assembly. Next, the block is disengaged from the conveyor pin by advancing the block downstream away from the conveyor pin with a faster-moving block advance pin. While maintaining the lower leading corner of the block against a pivot pin of the pivot pin assembly, the block is turned ninety degrees forward about the pivot pin using a flip pin of the flip pin assembly. After turning the block, the conveyor pin re-engages the block to push the block downstream through the trough.
