ABSTRACT:
A machine for automatically laying building blocks and the like into a panel. It includes a supply conveyor for feeding a predetermined number of blocks into the machine in proper sequence to form a course, the blocks standing on end. An in-feed support conveyor receives the blocks while still in upright position. A feeder carriage reciprocates over the in-feed conveyor and carries flow-guns for applying adhesive to the exposed upper ends of the blocks and to the exposed edges of the blocks at different times. The carriage is provided with clamps which, as the carriage advances, successively clamp the blocks for pivotal movement about transverse axes. Beyond the in-feed conveyor, is a course-forming and supporting conveyor which is transversely arranged relative to the in-feed conveyor and, over which the carriage advances, which has pairs of parallel guides for receiving the clamped blocks on the feeder carriage. As the blocks are moved by the advancing carriage into a pair of the aligned guides, they are tilted into horizontal positions, by movement about the transverse clamp axes, and arranged in the guides as a horizontal row of spaced blocks, and are later released by the clamps. The released blocks are slidably pushed together in the guides and centered relative to the conveyor by ram units so that they will adhere as a horizontal course. The course-forming and supporting guide conveyor is advanced inwardly or rearwardly intermittently to advance the formed course successively into engagement with a transfer unit which reciprocates rearwardly and forwardly above the conveyor to successively grip the adhered courses, and at the same time to align other pairs of guides successively with the rows of blocks supplied by the feeder carriage. The transfer unit moves the formed courses successively over a panel-support elevator where they are released, the elevator being lowered gradually so that the courses are laid thereon, with the courses then adhering to form a panel. Automatic programming and timing controls are provided for bringing about all of the operations in proper sequence.
