<p>PURPOSE:To improve the efficiency in manufacturing by placing a stoppage command to a working machine at the time when the sum of the number of windings delivered from receiving a stoppage command by a work machine until its complete stop and the number of windings to be left on a reel, and the remaining number of windings detected are coincided. CONSTITUTION:The metal foil A to be rolled is wound on a rewinding reel 1. In this case the number of windings N1 is measured in advance. On the other hand, the observed length of the foil A to be rolled which is re-wound is found and converted in the number of windings N2, until a work roll 3 is completely stopped after receving a stoppage command by a rolling mill. A remaining number of windings 3 is counted simultaneously with the start of the rolling mill and when N2 +N5 is coincident with N3, a stoppage command is placed to stop the rolling mill. In this way the generation of a defective product is prevented and an efficient manufacture can be realized.</p> |
