    Abstract: PURPOSE:To judge appropriate driving of an operating means, to know load variation as time goes by, and to detect malfunction of such as PID adjustor by detecting the on-rate of electrification actually carried out in an ON/OFF control system. CONSTITUTION:An on-rate counter 9 is connected to an electrification circuit 8 of an operating means that has an electrification circuit for ON/OFF control, and the electrification ON-time of the electrification circuit 8 is detected, while the rate of electrification 0N-time to predetermined cycle is calculated as on- rate, and the on-rate thus calculated is output.

    Abstract: PURPOSE:To clean a roll automatically with high efficiency by providing a cleaning head for removing dust adhered onto the surface of sheet carrying roll movably in longitudinal direction of roll while contactably/separatably against the roll. CONSTITUTION:When cleaning a sheet carrying roll 2, a motor 10 is first driven to travel a truck 5 along a rail 9 thus to move to the lower position of specific roll 2. Then a motor 14 is driven to move the rail 9 through a chain 13 in longitudinal direction Y of roll 2. Consequently, a cleaning head 3 mounted on the truck 5 is moved from the retreated position A to specific position B where the roll 2 is contaminated. Thereafter, the cylinder 7 is lifted to contact the cleaning head 3 against the lower face of roll 2 and to rub against the surface of roll 2 through rotation of roll 2 thus to clean off dust adhered onto the surface of roll.

    Abstract: PURPOSE:To prevent operation in the state of the actual pressing force of a contact roll remaining abnormal by detecting/displaying the air pressure in an air cylinder of in a position very close to the air cylinder in an air pipeline through an electropneumatic converter, thereby rapidly discovering the air leak of the air pipeline or the like and the abnormality of an electropneumatic converter control system. CONSTITUTION:A contact roll 13 for pressing each take-up product roll 3 is rotataly supported at the lower end part of an arm 15, and the roll 3 is provided with the specified pressing force by pushing the arm 15 by an air cylinder 12. The air pressure to the cylinder 12 is set to the specified value or the specified pattern by a controller 16, and its output signal 18 is sent to an electropneumatic converter 19 so that the initial air pressure 20 is controlled into target control pressure and then sent to the cylinder 12 through an air pipeline 21. An electropneumatic converter 22 is connected to the pipeline 21, in a position very close to the cylinder 12 or directly to the cylinder 12. The air pressure thus detected is inputted as a detection signal, and the detected air pressure is displayed on an appropriate display means 24.

    Abstract: PURPOSE:To enable the grasp of an air bite rate in every winding layer of a take-up roll so as to establish the optimum conditions of take-up speed, take-up tension, surface pressure, and the like by computing the air bite rate of the take-up roll during take-up action every fixed cycle from the winding diameter and winding length of the take-up roll, the thickness of sheet material and a take-up core diameter, and displaying the computed result. CONSTITUTION:The winding diameter D and winding length L of a take-up roll is inputted into an arithmetic means 20 first. In the arithmetic means 20, an air bite rate epsilon at that time is computed every fixed cycle by an illustrated expression on the basis of the take-up core diameter D0 and the film thickness (t) set before operation. The computed air bite rates epsilon1, epsilon2, epsilon3 are displayed on a monitor 21. In the monitor 21, the air bite rate in each winding layer regarding each take-up roll 3 can be thereby read moment by moment. This results in understanding what kind of air bite rate is obtained according to the conditions of take-up speed, tension, surface pressure, and the like so as to enable the grasp of conditions for obtaining the optimum air bite rate.
