っている。However, when winding the web with the above configuration by rotating the winding shaft at a constant rate, the amount of web feed differs at the beginning and end of the winding. As shown in Figure 1, which is a graph showing the change in the amount of web feeding with respect to the change in the diameter of the web winding shaft, the diameter of the winding shaft is 8. Accordingly, the amount of web feeding per unit time changes from the initial value to the final value of 1. Changes to At this time, the minimum value! However, the amount of feed is set to allow for complete leaning. Therefore, sending)
If the amount is 10 or more, the web is being fed in a wasteful amount more than the required amount, which impedes the web replacement interval of the web cleaning device. In other words, it is a drawback that shortens the lifespan.

している。In order to solve this drawback, it is conceivable that the web be fed in a fixed quantity by holding the web between rows 26 that rotate at a constant speed, as shown by broken lines in FIG. 1. This is a well-known method in the field of tape recorders. However, in the case of a web cleaning device, unlike a tape recorder, such an extremely precise feeding speed is not required. Further, at least one roller that rotates at a constant speed is required in addition to the curling shaft, the feeding shaft, and the pressing roller 3. Furthermore, in order to realize this method, it is necessary to apply tension to the web to prevent it from sagging, and it is necessary to rotate the winding shaft a little faster than the roller base. Therefore, a driving source is required at one location. Moreover, if the torque of the winding shaft q becomes larger than that of the roller 6, the roller Ad will no longer be used, and the amount of web winding will be determined by the winding shaft DA. In order to prevent this, it is necessary to provide a sliding mechanism or the like on the winding shaft to absorb a large amount of winding, but this has the disadvantage of complicating the device and increasing costs.

By controlling the amount of deposits, it is possible to feed cilanib in a constant amount, thereby extending the life of the web.Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows an embodiment of the present invention, and parts common to those in FIG. 1 are designated by the same numbers.

ブの一定量巻き上げを行っている。The tip of the arm 7 is pivoted on a shaft 10 which is in contact with the outer diameter of the booster O and is interlocked with the input part of the potentiometer, and is biased counterclockwise by a spring (not shown). A rotatable roller 1 is provided in the section. The webco is a motor (not shown) that rotates the winding shaft in the direction of arrow A.
As the outer diameter of the take-up shaft q increases, the amount of take-up follows the swing from the solid line position to the two-dot chain line position as the outside diameter of the take-up shaft q increases. The movement of the winding arm is detected by the potentiometer, and the winding is performed as shown in the figure. As the outer diameter of the winding shaft increases, the amount of rotation of the winding shaft is decreased, thereby winding up a certain amount of the shiranib. There is.

Q is a comparator, Q2 is a transistor for the driver, RI is a resistor, Q is a driver that controls ON/OFF of the motor, and the variable resistor ii of the potentiometer that detects the amount of web winding is used to control the web winding. This is to detect the amount taken and control the speed of the drive motor M.

とも可能である。In this embodiment, when the remaining amount of web on the feeding side reaches a small amount that requires replenishment, a signal is generated based on the position of the potentiometer to the position of the taper, and is displayed to the operator. . This signal is not emitted at one place as in this embodiment, but if the potentiometer measures the amount of positional displacement using electrical resistance, it is a change in the j# rule, so it is not always possible to determine how much power is remaining. It is also possible to calculate and display whether there is any.

できる。The remaining web amount can be known on the display device by emitting a signal indicating the remaining web amount by the web outer diameter detection means. Further, the means for detecting the outer diameter of the feeding shaft or the winding shaft is a means for detecting the outer diameter of the feeding shaft or the winding shaft.
Place the roller in contact with the outer diameter of the web O on the shaft at the end of the arm (b)
Since it is rotatably mounted and the arm is pivotally connected to a potentiometer, the outer diameter of the web can be determined with simple components.
