6with the definite proportionality constant of experimental technique.When 20Cong reference position, dancer unit is during to the second pulley R1, R3 and R5 rotation, the anglec of rotation x of dancer unit 20 is set to negative value, and when dancer unit 20 rotates from reference position on the rightabout of the second pulley R1, R3 and R5, the anglec of rotation x of dancer unit 20 be set on the occasion of.Aforementioned proportion constant can calculate according to the position relationship the distance from rotating shaft to the first pulley R2 and R4 and the first pulley R2 and R4 and the second pulley R1, R3 and R5.Can be identified for by different way by experiment calculating by the polynomial dimension of the length of the material (L) of dancer unit 20 suspensions.
The length of (L) of the material being hung by dancer unit 20 calculating according to the anglec of rotation of dancer unit 20 may be provided in look-up table, and computation processor 43 can be searched for according to the anglec of rotation of the dancer unit 20 from 42 transmission of PID measuring unit the length of the material (L) being hung by dancer unit 20.
The variation correction of the length of the material (L) that computation processor 43 is hung by dancer unit 20 by consideration is wound up into the radius of the material (L) on reel 31.Computation processor 43 can calculate with reference to the radius that is initially wound up into the material (L) on reel 31 radius of the material (L) reducing along with the driving of unwinding motor 30.Here, computation processor 43 is in the variation of the length of the material (L) of considering to be hung by dancer unit 20, and compensation is wound up into the radius of the material (L) on reel 31.
For example, when dancer unit 20 is when the initial point of winding process is disposed in reference position, the radius that is wound up into the material (L) on reel 31 is r, and the thickness of material (L) is d.If the time durations of length k has been reeled from reference position rotation anglec of rotation x at drive motor 10 by material (L) in dancer unit 20, the length of the material (L) being hung by dancer unit 20 is changed to the length y2 at the anglec of rotation place of position x from the reference position of the length y1 (=b) of x=0.Correspondingly, when drive motor 10 is during by material (L) coiling length k, from the length of the material (L) of reel 31 unwindings, become k+ (y2-y1).If y2-y1=-2pr, the little 2pr of length of the material (L) of being reeled by drive motor 10 from the Length Ratio of the material (L) of reel 31 unwindings.Correspondingly, the radius ratio material (L) that is wound up into the material (L) on reel 31 large d during from reel 31 unwinding, for example, the thickness of the material of being reeled by drive motor 10 (L).
That is to say, the radius that is wound up into the material (L) on reel 31 changes according to the length of the material (L) being hung by dancer unit 20, and computation processor 43 offset value calculation, to be compensated the radius of the material (L) being wound up on reel 31 by the length variations of the material (L) of dancer unit 20 suspensions by consideration.Computation processor 43 transfers to PID controller 44 by the radius information of having considered the material (L) of offset.
