By foregoing description, the above-mentioned cable windings method that the present invention provides, turn owing to first wrapping post being fixed on On dynamic disk, and being fixed by the first end of cable, then the front portion at described rotation disk arranges lifting platform, described lifting Platform rises the height equal with described cable diameter, further according to described line automatically for ordering about when described rotation disk rotational one encloses Cable and the change of the position of the intersection point of described rotation disk, at the second end applying balancing force of described cable, make described cable exist Each moment stress in rotation process is the most equal, the most both can guarantee that the binding of operation below and line taking process were smoothed out, It is avoided that again the generation of the slack and undisciplined phenomenon of coiling.

The second cable windings method that the present invention provides, is on the basis of the first cable windings method above-mentioned, also Including following technical characteristic:

Described the second end at described cable applies balancing force and is:

Utilize PLC to control the electric current of servomotor input real-time change, utilize the electric current of described real-time change at described line Second end of cable applies balancing force.

It should be noted that utilize PLC to control servomotor to control the output of electric current, it is a kind of conventional method, By accurately analyzing the size of the required balancing force applied, calculate the size of the electric current that needs compensate, as base Plinth controls the output of electric current, it becomes possible to power cable suffered by is effectively ensured the most equal in each moment, thus solves cable Loose problem.

The third cable windings method that the present invention provides, is on the basis of above-mentioned the second cable windings method, also Including following technical characteristic:

When the angle that rotation disk turned within the t time is less than critical angle, the first size of current of described real-time change For:

$I^{\′}=\frac{f+lR\sin \mathrm{\ω}t+I}{C_M\mathrm{\Φ}}$

Wherein, f is the frictional force that described rotation disk is subject to, and l is that the outlet point of described cable is in described rotation disk The distance of the heart, R is the radius of described rotation disk, and I is the rotary inertia of described rotation disk, C_MFor torque constant, Φ is magnetic Logical.

The 4th kind of cable windings method that the present invention provides, is on the basis of the third cable windings method above-mentioned, also Including following technical characteristic:

When the angle that rotation disk turned within the t time is more than critical angle, the second size of current of described real-time change For:

$I^{\′\′}=\frac{\frac{\sin \mathrm{\ω}t(l^{3}R-{\mathrm{lR}}^3)}{l^2+R^2-2lR\cos \mathrm{\ω}t}+f+I}{C_M\mathrm{\φ}}$

The 5th kind of cable windings method that the present invention provides, is at above-mentioned the third or the base of the 4th kind of cable windings method On plinth, also include following technical characteristic:

In once for every half, whenTime, described rotation disk turns to described critical angle position.

Concrete, it is the cable stress analysis when the angle that rotation disk turns over is less than critical angle referring initially to Fig. 2, Fig. 2 Figure.

Wherein, l is the cable outlet point distance to disc centre, and R is the radius of disk, and wherein the size of critical angle θ is (i.e. The size of the angle θ as ∠ ACO=90 °), cable go out and a little determine to the distance of disc centre and the radius of disk, then θ= arccos(R/l)；Moment produced by motor is M, and cable Moment size is M', and the frictional force that disk is subject to is f, disk Rotary inertia be I；Then the moment suffered by cable is M'=M-f-I；If the angle that disk turned within the t time is α=ω T, as α≤θ, owing to using permanent magnetism cam servomotor, by its moment formula M=C_MφI(C_MFor torque constant, φ is Magnetic flux) understand, when the electric current of input motor is certain, and moment produced by motor is certain；Moment suffered by cable is permissible Be expressed as F, then F can be expressed as F=AB r.

By cosine formula C²=A²+B²-2ABcosC understands:

AB²=l²+R²-2lRcosα

$AB=\sqrt{l^2+R^2-2lRcos\mathrm{\α}}$

By sine:Understand:

$\sin \mathrm{\β}=\frac{R\sin \mathrm{\α}}{AB}$

Then the moment suffered by cable is:

For sine curve figure, then

F=M'

Therefore F=M-f-I

Owing to the value of M, f, I is for determining value, so M=F+f+I

M'=C_Mφ I'=F+f+I

So

$I^{\′}=\frac{f+lR\sin \mathrm{\ω}t+I}{C_M\mathrm{\Φ}}$

On the other hand, as θ ＜ α≤Π, it is when the angle that rotation disk turns over is more than critical angle with reference to Fig. 3, Fig. 3 Cable stress analysis chart, from figure, as long as crossing C point, cable all can have two intersection points with the movement locus of circle, i.e. this Time:

AB=AB'+BB "

Understand

By sine:

$\sin \mathrm{\β}=\frac{R\sin \mathrm{\ω}t}{AB},cos\mathrm{\β}=\sqrt{1-\frac{R^2{\sin }^2\mathrm{\ω}t}{{\mathrm{AB}}^2}}$

If B'B " chord length be d:

Then

So

Rope Moment M=AB r

$\begin{array}{c}M=lR\sin \mathrm{\ω}t+2R(\sqrt{1-\frac{R^2\sin \mathrm{\ω}t}{{\mathrm{AB}}^2}}\cos \mathrm{\ω}t-\frac{R{\sin }^2\mathrm{\ω}t}{AB})\·\frac{R\sin \mathrm{\ω}t}{AB}\\ =lr\sin \mathrm{\ω}t+2{\mathrm{lR}}^2\sin \mathrm{\ω}t(\sqrt{\frac{1}{{\mathrm{AB}}^2}-\frac{R^2{\sin }^2\mathrm{\ω}t}{l^2+R^2-2lR\cos \mathrm{\ω}t}}\cos \mathrm{\ω}t-\frac{R{\sin }^2\mathrm{\ω}t}{{\mathrm{AB}}^2})\\ =lR\sin \mathrm{\ω}t+2{\mathrm{lR}}^2\sin \mathrm{\ω}t(\sqrt{\frac{l^2+R^2\cos \mathrm{\ω}t-2lR\cos \mathrm{\ω}t}{{(l^2+R^2-2lR\cos \mathrm{\ω}t)}^2}}\cos \mathrm{\ω}t-\frac{R{\sin }^2\mathrm{\ω}t}{l^2+R^2+2lR\cos \mathrm{\ω}t})\\ =lR\sin \mathrm{\ω}t+2{\mathrm{lR}}^2\sin \mathrm{\ω}t\left(\frac{1-R\cos \mathrm{\ω}t}{l^2+R^2-2lR\cos \mathrm{\ω}t}\cos \mathrm{\ω}t-\frac{R{\sin }^2\mathrm{\ω}t}{l^2+R^2-2lR\cos \mathrm{\ω}t}\right)\\ =lR\sin \mathrm{\ω}t+2{\mathrm{lR}}^2\sin \mathrm{\ω}t\left(\frac{1\cos \mathrm{\ω}t-R}{l^2+R^2-2lR\cos \mathrm{\ω}t}\right)\end{array}$

$\begin{array}{c}=\frac{lR\sin \mathrm{\ω}t+{\mathrm{lR}}^3\sin \mathrm{\ω}t-2l^2{R}^2\sin \mathrm{\ω}t\cos \mathrm{\ω}t+22l^2{R}^2\sin \mathrm{\ω}t\cos \mathrm{\ω}t-2{\mathrm{lR}}^3\sin \mathrm{\ω}t}{l^2+R^2-2lR\cos \mathrm{\ω}t}\\ =\frac{\sin \mathrm{\ω}t(l^{3}R-{\mathrm{lR}}^3)}{l^2+R^2-2lR\cos \mathrm{\ω}t}\end{array}$

Therefore F=M-f-I

Owing to the value of M, f, I is for determining value, so M=F+f+I

So M'=C_Mφ I=F+f+I

$I^{\′\′}=\frac{F+f+I}{C_M\mathrm{\φ}}=\frac{\frac{\sin \mathrm{\ω}t(l^{3}R-{\mathrm{lR}}^3)}{l^2+R^2-2lR\cos \mathrm{\ω}t}+f+I}{C_M\mathrm{\φ}}$

Owing to l and disk coiling radius are certain, then the size understanding critical angle θ is known, it may be assumed that

θ=ω t=arccos (R/l)；

$t=\frac{arccos\frac{R}{l}}{\mathrm{\ω}}$

In sum, i.e. in once for every half when disk rotational to critical angle position, i.e. as T ＜ t, I' is mended Repay；As T ＞ t, to I " compensate, therefore according to corresponding electric current I' and I " it is compensated, i.e. can reach cable The purpose of uniform force.
