<p>PURPOSE: A tension control apparatus for a damper, a collector, and a conveyor is provided to detect slack of the connection line and to control the tension automatically through the controller. CONSTITUTION: A tension control apparatus for a damper, a collector, and a conveyor comprises a connection line(21), a body(52), a hydraulic unit(32), a link body(33), a limit sensor(30), and a controller(31). The connection line surrounds the outer surfaces of rolls(10,20). A guide block(58) connected to a shaft(57) of one roll is installed to slide inside the body. The hydraulic unit is fixed to one side of a gas frame. One end of the link body is in contact with the guide block. The guide block includes a stopper for preventing retreat of the guide block. The limit sensor is connected to one side of the connection line at an interval. The controller regulates the hydraulic unit to push the line member when the limit sensor detects slack of the connection line.</p> |
