Abstract

PURPOSE:To adjust the inclination before meandering of the strip by setting the sensors at both right and left ends of the carriage, detecting and calculating the inclination of the carriage and its change with the lapse of time. CONSTITUTION:The sensors 2 are set at both right and lift ends of the carriage 1 and at both fixed parts 3 opposite to the above so as so sense with right and left at the same time if the carriage 1 is in the horizontal state. When the carriage 1 is moved up and down as it is in this state, the both right and left sensors 2 sense at the same time. If the carriage 1 elevates or lowers in the inclined state caused on the generation of the stretch of the wire rope 6 hanging the carriage 1, etc., the difference ( t) of the sensing time is generated at the both right and left sensors. By detecting this deference of sensing time, the inclination of the carriage 1 can be known. And the inclined quantity ( h) is obtd. by multiplying the speed (v2) of elevating/lowering of the carriage 1 by the difference ( t) of detected time, i.e., it can be calculated as h=v2X t.
