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: PROBLEM TO BE SOLVED: To provide a detecting device which can clearly image-display a tape end in the width direction of a laminate tape. SOLUTION: A laminate tape 1 is composed by gluing a synthetic resin separative film tape whose tape width is smaller than that of a synthetic resin basic material film tape onto the upper face of the synthetic resin basic film tape, and transported from a left side to a right side. A projector 3 projects light and at the same time an irradiation means 5 downward irradiates. Therefore a detection spot is picked up by a CCD camera to be displayed in an image display device 6. In this case, a dichroic filter 7 transmits only light whose color component is damped at a fixed rate from light from the projector 3. On the other hand, light transmitted the laminate tape 1 and the reflected light of downward irradiating light are incident upon the dichronic filter 8, and their transmitted light is inputted to the CCD camera 4. Therefore, both the width direction end of a base material film tape and the width direction end of a separative film tape can be clearly image displayed in linear form.

Abstract: PURPOSE: To provide a device for detecting the defect of a sheet-shaped object capable of automatically and accurately detecting the type, size, and position of the dent defect or internal defect of the sheet-shaped object. CONSTITUTION: The defect detecting device 5 is formed by a light projector 7A for applying illumination light Q to an expandable sheet 1a with a dent defect 1b and an internal defect 1h (Fig. 9), a light receiver 8A for receiving reflection light R and outputting defect information as an image signal, and an image processing device 9 for electrically processing the image signal from the light receiver. The light projector 7 applies light to a position which is at a specific inclination angle of θ1 and where the application point is offset from a defect position by a specific distance E and at the same time, the light receiver 8A employs a diffusion reflection lighting system where a reflection angle θ2 of the reflection light from the defect point is within 70-90 degrees for a sheet-shaped object plane. Also, an image processing device 9 employs a differential system.

Abstract: PURPOSE:To form a water screen having uniform thickness on a casting drum by controlling an air quantity to be supplied to a moist air generating means with a predetermined relation in accordance with screen manufacturing speed of a resin film. CONSTITUTION:A quantity of air to be supplied to a moist air generating device 80 is controlled based on a result obtained in such a manner that a signal obtained from a rotation speed detecting means 120 of a casting drum 4 or a speed measuring means 130 of a resin film is computed by a control device 1351. When the air quantity to be supplied is represented by Q at atmospheric pressure per unit length of a main moist air blowoff device 21 in a direction along the rotation of a casting drum 4 and an auxiliary moist air blowoff device 22 and when control is to be performed by the signal from the rotation speed detecting means 120 of the casting drum 4, the control is performed by Q=a1V+b1 to a rotation speed V of the surface of the casting drum, where 0.10

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.
