PURPOSE:To automatize operation and minimize the quantity of wastes by detecting the rear end and the front end of a strip and carrying out required number of feeds and cuts of a defined cutting quantity and removing unnecessary parts, in the captioned device for a steel plate production line. CONSTITUTION:The front end of a steel plate 6 on a roll 5 is sent into an end plate treating device 1 via pinch rolls 3D and a strip inlet 8D, the position of the front end is detected by an end part position detector 23D, and positioning is made so that the front end comes between shears 12 to carry out cutting. Then, a constant quantity feed and cut for removal is repeated to obtain a defined removing quantity. Steel plate pieces cut off for removal are carried out by an end plate disposing conveyor 14. For treating the rear end of a steel plate on a coil 4, when a rear end enters between rear end shears 11, the rear end is cut off 31 in a welder 2 and sent in the opposite direction by the operation of an end part detector 23U and cut off. This operation is repeated for a required number of times. Due to this construction, the operation can be automatized while minimizing the quantity of waste. |
