COIL DEPLETION SENSOR |
摘要 |
<p>A control device for a continuous processing line which is fed material from a coil utilizes information regarding the outside diameter of the material on a coil having a constant inside diameter as a basis for its control functions. A typical application is in the control of a strip accumulator (15) in n strip processing line wherein strip (8) on a revolvable coil is drawn from an uncoiler (10) by the revolvable pinch rolls (16) of the accumulator at which point a certain quantity of material is stored so that when the end of a coil is reached a new coil may be attached to the old coil without stopping the line. In such instances it id highly desirable that the accumulator be substantially filled so that a maximum time is available to attach the new coil. The control device includes means (31) providing a signal proportional to the revolutions of the pinch rolls and means (30) providing a signal proportional to the revolutions of the supply coil. The pinch roll revolutions are counted by a counter (38) and if the counter receives the signal proportional to the revolution of the supply coil after counting a predetermined number of pinch roll revolutions, it is reset to count again until such time that the counter does not reach the predetermined number of counts before receiving a supply coil revolution signal at which time accumlator control is initiated.</p> |
