Title: Tension control method for continuous rolling mill
Inventor: KIMURA KAZUYOSHI
IPC: B21B37/00
Filed: 1989-07-04
Abstract: PURPOSE:To control accurately tension by performing estimate operation of tension between stands and also the component of torque due to load from the armature current, terminal voltage and number of revolution of drive motor for roll without use of rolling torque. CONSTITUTION:Because fluctuation of the component of torque due to rolling load is enough slow compared with fluctuation of tension between stands, tension between stands and also the component of torque due to the above load are estimated from armature current, terminal voltage and number of revolution of the drive motor for roll without use of rolling torque. Differentiation of torque arm and number of revolution are included in the arithmetic expression of rolling torque and further the plate thickness on the inlet side, the plate thickness on the outlet side and the opening of roll are included in torque arm, so everything has many errors. Therefore, error at the above operation of torque arm and rolling torque is nothing. Thereby, tension can be accurately operated and tension control can be performed without use of looper.

Abstract: PURPOSE:To aim at enhancing the availability of sheets to be conveyed on a first conveying path, by detecting remaining sheets on a second conveying path so that normal sheets are fed again onto the first conveying path while abnormal sheets are accumulated in a reject section. CONSTITUTION:When postal mediums P clogs up on a first conveying path 2, a first gate is rotated in the direction of the arrow so that the conveying direction of the postal mediums P is turned into toward a second conveying path 10, and simultaneously, the conveying path 2 is stopped. Then, after the clogging postal mediums P are removed from the second conveying path, when restarting is made while the remaining postal mediums P are left to be as they are, a first take-out mechanism in a supply section 1 is not at once driven but the conveying path 2 is started first. Accordingly, the remaining postal mediums P on the conveying path after the gate 9 are stored in a reject stacker 8 while the remaining postal mediums P on the conveying path before the gate 9 and on the conveying path 10 are accelerated on the conveying path 10 and are merged together just before a detecting section 3, and thereafter, they are conveyed into the detecting section at a constant speed. Accordingly, not all remaining postal mediums on the first conveying path are stored in the stacker, and thereby it is possible to enhance the availability.

IPC: F03D11/02
Filed: 1986-07-22
Abstract: PURPOSE:To make it possible to smoothly and satisfactorily operate a wind power driven rotary drive mechanism with a high degree of accuracy and to make the mechanism compact, by automatically selecting one of input power sources in accordance with the degree of wind power and the degree of load exerted to a rotary shaft. CONSTITUTION:The rotary motion of a wind power driven pipe shaft 4 is decreased in its rotational speed, and is transmitted to a center rotary shaft 2 by revolution of planetary gears 14 through a gear attaching member 13 so that the load exerted to the wind power driven rotary pipe shaft 4 is reduced. When the wind power is lower or the load on the working side increases exceeding a predetermined value, the self-rotation of a wind power driven rotary ring member 8 is interrupted, but the window power drive rotary pipe shaft 4 is rotated even under lower wind power so that the transmission of input energy is automatically changed over into the wind power driven rotary pipe shaft 4 side and therefore, the rotation of the center rotary shaft 2 is continued. Thus, the center rotary shaft 2 is rotated by the wind power rotary pipe shaft 4 or the wind power rotary ring member 8 as an input power source which is automatically selected in accordance with the degree of wind power and the degree of load exerted to the center rotary shaft 2 at that time, and therefore, output energy may be continuously produced.
