を発する。A deterioration determination circuit is provided separately or attached to the tension control device, and the tension of the running paper that is kept constant and detected by the tension detector of the running paper and the gradually changing diameter of the web are input to this circuit. Then, the brake torque determined only by this tension and diameter is calculated, and the braking force Fi applied to the support shaft necessary to output this brake torque and the brake Fa actually applied to the brake device of the support shaft, That is, the output from the tension control device including the deterioration of the braking device (the output to the braking device) is compared, and if the difference between Fi and Fa exceeds a preset value, it is judged as deterioration or abnormality and a warning is issued.

で劣化の度合を判定し得る。The braking device deteriorates as it is used, and the difference between the calculated braking force Fi and the actual braking force Fa becomes larger than the difference that occurs when a new product is used. Therefore, the degree of deterioration can be determined by comparing the difference between Fi and Fa.

装置８に指令する。As shown in FIG. 1, the deterioration determining device for a braking device according to the present invention has a deterioration determining circuit 9 additionally provided to the tension control device 7 installed in the paper feeding device described in FIG. The deterioration determining circuit 9 outputs a signal regarding the tension T, which is kept almost constant, from a tension detector 6 of the guide roller 5 (by a commonly used detection method) and a signal regarding the diameter D of the web (running). The traveling speed of the paper and the detection method that is generally used depending on the number of rotations of the support shaft 4 of the paper roll and the like) are input as electrical values. The brake torque in the steady state is calculated from these values, and the theoretical command Fi to be applied to the brake device 8 necessary to generate this brake torque is calculated. On the other hand, from the tension control device 7, the control command Fa actually applied to the braking device 8
Is input to the deterioration determination circuit 9. Since the tension control device 7 always operates so as to keep the tension of the traveling paper constant, when the brake device 8 deteriorates, the brake device 8 is instructed to compensate for the deterioration.
従って、ブレーキ装置８の劣化により発生トルクが減少

レーキ装置の異常により発生トルクが増大した場合指令
Faは減少してFaとFiとの差が大きくなる。この差が予め
設定された値以上になるとブレーキ劣化又は異常として
警報等を含めた警告が出される。Therefore, when the generated torque decreases due to deterioration of the brake device 8, the command Fa from the tension control device 7 increases, and conversely, when the generated torque increases due to the abnormality of the brake device, the command Fa increases.
Fa decreases and the difference between Fa and Fi increases. When this difference exceeds a preset value, a warning including an alarm and the like is issued as brake deterioration or abnormality.
なお、輪転機の加減速中は、ブレーキ装置８への指令は
一義的に算出できないため、劣化判定は行なわないよう
にインタロツクを取っている。During the acceleration / deceleration of the rotary press, the command to the brake device 8 cannot be uniquely calculated, so an interlock is made so that the deterioration determination is not performed.
