IPC: D01H1/36
Filed: 1994-06-22
Abstract: PURPOSE:To reduce end breakage in restarting of a frame after unexpected suspension of the frame such as power failure or abnormal suspension. CONSTITUTION:A lifting drive system is driven by a servo motor and a spindle drive system is driven by a main motor. In restarting after abnormal suspension of a frame, the spindle drive system and the lifting drive system are synchronously driven and a ring rail is moved from a suspension position downward until the revolving speed of the spindle reaches a fixed value (alpha). When the revolving speed of the spindle reaches the fixed value (alpha), the position of the ring rail is judged whether it is a position possible to continue normal lifting and lowering actions or not. When the position is a possible position, the lowering is continued and after the ring rail reaches the lower end of normal lifting and lowering movement, a central treating device is transferred to a normal lifting and lowering program. When the position is not the possible position, the ring rail is moved to a zone capable of continuing the normal lifting and lowering movement and the central treating device is transferred to the normal lifting and lowering program.
