ABSTRACT:
A material magazine for automatically feeding material such as long steel bars to a metal working machine including at least two parallel chain-conveyers, material guide rollers, a material arrival detecting means, and a material feed roller. The chain-conveyers are driven by a hydraulic motor which runs with a predetermined rotating force continuously produced when overloaded and have material push rollers with the axes vertically upward of the carrying faces of the chain-conveyers. The material push rollers are not only spaced in the direction of the conveyers but also arranged to form straiaght rows in the direction perpendicular to the conveyers, forming material holding spaces between them in the direction perpendicular to the conveyors. The material guide rollers are provided at or near one end of each of the conveyers with the axes kept vertical so that the material guide rollers may be arranged straight and parallel to the rows of the material push rollers. A material arrival detecting roller and material feed roller are provided along the material guide rollers. The material arrival detecting roller includes a vertical roller with the axis not rigidly fixed but slightly slidable and mechanically interlocked with a switch. The material feed roller feeds the material having arrived at the material guide rollers toward an index vise of the sawing machine along the length direction of the material.
