A workpiece conveying and feeding unit for conveying a long workpiece in the lengthwise direction to feed the workpiece to a cutting machine is disposed in the rear of the cutting machine. A workpiece conveying unit conveys the workpiece in the lengthwise direction of the workpiece into a workpiece conveying passage of the workpiece conveying and feeding unit. When a plurality of workpieces placed on the workpiece conveying unit are sequentially conveyed to the workpiece conveying passage of the workpiece conveying and feeding unit to convey the workpieces to the cutting machine, the side surface of the workpiece which is conveyed to the workpiece conveying passage of the workpiece conveying and feeding unit by the workpiece conveying unit is detected by a side-surface detector. In accordance with the conveyance distance calculated in accordance with the diameter of the workpiece, the side surface of which has been detected, and the positional relationship between the workpiece conveying passage and the side-surface detector, the workpiece is located on the workpiece conveying passage.

Method and apparatus for feeding workpiece

A bar storage apparatus comprises: a shelf frame (19) provided with a plurality of pallet accommodating shelves (17) each for movably accommodating a pallet (15) on which a plurality of bars are mounted; an elevator device (23) disposed on one side of the shelf frame so as to be movable up and down and provided with a traverser (21) for moving each pallet into and from each of the pallet accommodating shelves; and a bar supplying device (25) for supplying a bar, mounted on the pallet moved from the pallet accommodating shelf and further located at a predetermined position by the elevator device, to a bar processing machine (3). The bar storage apparatus can store a great number of bars of various kinds and various dimensions, select any required bars from a great number of bars, and supply the selected bars to a bar processing machine easily and quickly.

Bar storage apparatus

A method for conveying a long workpiece to a cutting machine includes the steps of conveying a long workpiece laterally to a feed conveyor positioned in parallel with the path line of the cutting machine by a cross conveyor extending in the lateral direction of the workpiece; stopping the cross conveyor when a workpiece reaches a regulating member provided above the cross conveyor, in a line parallel to the path line of the cutting machine; moving the feed conveyor with respect to the cutting machine path line in response to the workpiece width so that the feed conveyor is located at a position for selectively scooping up the workpiece; moving at least one of the feed conveyor or the cross conveyor in the vertical direction so that the workpiece is selectively loaded on the feed conveyor; and conveying the loaded workpiece to the cutting machine by the feed conveyor. A workpiece conveying device for conveying a long workpiece to a cutting machine, includes a cross conveyor for conveying the workpiece laterally to the direction normal to the cutting machine path line; a regulating member for regulating the position of the workpiece in alignment with the cutting machine path line; a feed conveyor disposed parallel to the cutting machine path line; a position adjusting means for adjusting the position of the feed conveyor in the lateral direction; and a vertical operating device for moving a part of the cross conveyor in the vertical direction.
