Abstract: PURPOSE:To assure the winding form at a fixed level or above and prevent the occurrence of a large quantity of loss by warning an abnormality to process it before a large adverse effect is given to the winding form of a winding product roll when the control abnormality of each operation condition occurs. CONSTITUTION:When the actual control value of each operation condition differs from the preset instruction value by the preset ratio or above continuously for a preset period or longer in a sheet-shaped object slitter, the situation is judged as abnormal, and a warning signal is issued.

Abstract: PURPOSE:To correctly control the actual winding tension to a target value by correctly grasping the mechanical loss changed by the rotating speed of a winding shaft or as the time elapses and the mechanical loss component changed in response to the weight of a winding product roll or the face pressure of a contact pressure roll, and performing the optimum mechanical loss compensation. CONSTITUTION:The rotating speed of a winding drive source is automatically changed in the winding core fitting no-load state, the load current of the winding drive source is detected and stored, and the load current and the winding tension generating instruction current partition are added to obtain the instruction current to the winding drive source. The winding drive source is rotated in the winding product roll fitting no-load state, the mechanical loss component caused by the product weight is calculated, and it is added to the instruction current to the winding drive source. The mechanical loss component caused by the face pressure of a contact pressure roll is detected and calculated, and it is added to the instruction current to the winding drive source.

Abstract: PURPOSE:To prevent the generation of various kinds of trouble caused by oscillation during acceleration/deceleration and obtain the optimum thickness unevenness moderating effect by controlling the reciprocating speed performed by an oscillation device into the speed proportional to the sheet material conveying speed. CONSTITUTION:Oscillation for moderating the unevenness of film thickness in raw material 2 is performed by reciprocating a winding-out frame 15 by a hydraulic cylinder 17. In the speed control of this oscillation, the oscillation speed Vo proportional to the film carrier speed Vc detected from the speed of a guide roll 5 and the like is set previously, so that the oscillation speed Vo corresponding to the detected speed Vc is read out and set as the command value of the oscillation speed at that time. The position in the film width direction is detected by a magnetic scale 23, and the actual oscillation speed is computed on the basis of the difference between the present detection value and the preceding detection value. Solenoid flow control valves S1, S2 then control in such a way that actual oscillation speed coincides with the command value.

Abstract: PURPOSE:To enable control into the desired pressing force even in the case of using a contact roll of different self-weight by controlling the air pressure of an air cylinder in such a way as to place the contact roll into the preset neutral position before bringing the contact roll into contact with a take-up core. CONSTITUTION:The position of a roll 13 is detected by a photo-sensor 21 before a take-up core 15 is brought into contact with a contact roll 13. The air pressure of an air cylinder 12 is then controlled through an electropneumatic converter 19 so that this detected position is placed into a neutral position. At this time, the self-weight elements of the roll 13 and an arm 16 are balanced with the force by the air cylinder 12, and the roll 13 stands still in the neutral position. The air pressure in this neutral position is stored as the base pressure, and air pressure required for the generation of pressing force to the take-up core 15 is added to this base pressure at the take-up time so as to be made into the actual control pressure for performing take-up. The pressing force can be thereby controlled accurately regardless of change in the self-weight of the contact roll 13.

Abstract: PURPOSE:To prevent the weaving when a wound layer body is wound and prevent the drift or snaking when the wound layer body is unwound by suppressing the residual tension of the wound layer body low, and suppressing the air biting factor near the winding end section of the wound layer body in particular to a preset value or below. CONSTITUTION:The winding tension is reduced and the winding speed is lowered near the winding end of a wound layer body to control the air biting factor near the winding end to a preset value or below in the winding method of a plastic film. The residual tension at a surface layer section is made equal to or below the residual tension at an inner layer section, and the air biting factor at the surface layer section is suppressed to the preset value or below in the wound layer body of the plastic film.

Abstract: PURPOSE:To prevent the occurrence of a trouble such as the tearing off of a selvage section by invariably controlling the selvage section winding tension to the optimum value in response to the trim of the selvage section changed by oscillation. CONSTITUTION:In a sheet-shaped object slitter with an oscillation device on the unwinding side, the winding tension of a selvage section is controlled in proportion with the trim of the selvage section changed by oscillation, and the winding tension is invariably controlled to the optimum value in response to the trim of the selvage section at that time.

Abstract: PURPOSE:To reduce the pressure difference between the inside and the outside of an oil seal and prevent an oil from leaking, by a method wherein a lubricating oil is supplied to an object to be lubricated by a compressed gas, and a mixed fluid of the gas and the oil is sucked in through the object. CONSTITUTION:The compressed gas and the lubricating oil are supplied into a mixer 1 respectively through pipes 8, 9, the mixed fluid of the gas and the oil is discharged through a pipe 10 to lubricate the object 2 to be lubricated, the heat generated in the object 2 is absorbed through heat transfer, and the mixed fluid is separated into the gas and the oil by a gas-liquid separator 3. The gas is exhausted through an exhaust port of a sucking device 5, while the oil is stored in a tank 4, and is supplied to the mixer 1 by a pump 6, thereby forming a circulating line.
