The object of the present invention is to obtain a contact pressure control device capable of carrying out feedback control enduring a practical use by inventing a pressure detecting means and the employment structure of the same. The contact pressure control device of the take-up winder comprises a bobbin holder 5, a contact pressure roller 11 contacted against the bobbin B set on the bobbin holder 5, a slide supporting mechanism (s) for supporting the contact pressure roller 11 elevating or descending to the machine main body 2 , and a contact pressure cylinder 13 freely adjusting the contact pressure of the contact pressure roller 11 and the bobbin holder 5. Moreover, a load cell 16 is provided directly below one contact pressure cylinder 13 located between a pair of slide supporting mechanisms (s), (s). Furthermore, a print circuit board for controlling is provided for controlling the contact pressure cylinder 13 based on the detected value of the load cell 16 so that the contact pressure is to be maintained at a designated value.
A take-up winder comprising:
A take-up winder comprising:
A take-up winder for measuring repetitively a load acting upon the contact pressure cylinder while supplying air to the contact pressure cylinder or while releasing the air from the contact pressure cylinder for fixing the contact pressure of the bobbin holder, the package and the contact roller at a designated value, and for diagnosing whether or not there is an abnormality in the elevation and descending of the slide box which supports the contact roller according to the fact of whether or not the load is within a tolerance range.
A take-up winder comprising:
