Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a web division winder control device that divides a supplied web into a plurality of strips and winds the divided webs by uniaxially distributing the webs, or winding the webs forward and backward.

2. Description of the Related Art The function of an expander roll in a winder device is mainly to prevent wrinkles on the web, to improve separation of roll end faces (slit faces) between take-up rolls, and to obtain better roll end faces. However, in order to make full use of the function, the present situation is that the angle of the expander roll is conventionally set by human eyes.

[Problems to be solved by the device]

However, in the expander roll system of the winder device, the setting of the holding angle is determined by humans according to the intuition, the paper quality, the web speed, etc., and a setting means cannot be quantitatively found. In addition, the setting of the angle of the expander roll is forced to rely on manual operation, and even in that operation, the winder speed cannot be followed. Therefore, when the winder speed is increased or decreased, or when the winder speed is low, the winding roll end surface is not aligned (misalignment).
Moreover, when the winder speed is low, the time after which the web after the slitter is in contact with the expander roll is naturally long, and therefore the web after the slitter is expanded strongly and the running property in the width direction of the web is kept constant. In the end, the winding roll end surface was not uniform (edge misalignment). An object of the present invention is to provide a winder controller that detects the speed of a web wound by a winder and automatically and swiftly controls the angle of the expander roll to an optimum position in order to solve the above-mentioned conventional drawbacks. It is in.

[Means for Solving the Problems]

The present invention relates to a winder device that winds a web divided into a plurality of strips by a slitter, a speed detector for detecting a winder speed, a calculator for setting an angle of an expander roll by a detection value of the speed detector, The winder controller is characterized in that a positioner for adjusting the angle of the expander roll is provided by a signal of the arithmetic unit to control the angle of the expander roll.

[Action]

The winder controller of the present invention is a conventional manually variable type expander roll holding angle in order to keep the running properties of a plurality of divided webs after slitting in the width direction constant regardless of changes in winder speed. The amount is calculated relative to the winder speed, and the signal is used to control the angle of the expander roll, to prevent wrinkles from occurring on the web and to eliminate defects on the end surface of the winding roll. .

【Example】

The present invention will be described with reference to the drawings. FIG. 1 is a schematic view of an embodiment of a winder control device of the present invention, and FIG. 2 is a plan view of an expander roll. The web 2 pulled out from the base paper roll 1 laid on the reeler is divided into the base paper 2 after passing through the transport rolls 3, the dancer rolls 4, the tension detecting rolls 5, the fid rolls 6, the slitters 7, the expander rolls 8 and the proximity rolls 9. Is wound as a split winding roll 10. The web speed is detected by the speed detector 12 of the speed signal of the winding motor 10 for the winding roll 10 and the signal is sent to the expander roll in real time to the angle setting calculator 13
To input the angle of hold depending on the winder speed. The signal from the calculator 13 is sent to the positioner 14 for adjusting the included angle amount of the expander roll 8. A worm gear is provided on the support portion of the expander roll 8, and a signal from the positioner 14 is input to the worm gear drive motor 15 to operate the worm gear drive motor 15 to drive the second gear.
As shown in the figure, the expander roll 8 is automatically controlled in such a manner that the angle of inclination of the expander roll 8 is increased at high speed, and conversely, at the time of low speed, the angle of inclination is decreased.

[Effect of device]

The present invention, the wrinkle of the web of the winding roll due to the speed change in the split winder, the end face defect (deviation)
Can automatically control the angle angle of the expander roll after slitting in relation to the winder speed, and has the effect of stably eliminating the above defects.
