The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, the structure of feeding of the present utility model and embossing electric device embodiment is, comprise main control module 10, main control module 10 and man-machine interface 1, coder transitions module 3, SITOP power supply 4, tension pick-up 5, near switch 6, optoelectronic switch 7, reactor 9, power module 11 connects respectively, coder transitions module 3 is connected with encoder 2 on the main motor, encoder 2 is used to gather the rate signal of main motor, reactor 9 is connected with wave filter 8, power module 11 is connected with motor module 12, motor module 12 and feeding motor 13, embossing motor 14 connects and composes two independent control closed-loop paths respectively.Main control module 10 is selected SIMOTION motion-control module structure for use,

Tension pick-up 5 is arranged on embossing feeding portion and embossing driving section, measure the real-time tension signal of strip, be arranged on the embossing driving section, be used to control the measurement of embossing alignment scope near switch 6, optoelectronic switch 7 is arranged on the embossing driving section, is used to control the measurement of embossing alignment precision.

The operation principle of feeding of the present utility model and embossing electric device is,

1) to the collection of main motor speed.Gather the speed V1 signal of main motor with encoder 2, by its interface coder transitions module 3 the TTL signal is converted to the Drive_CLiQ signal, be connected to main control module 10, draw feeding principal velocity controlled quentity controlled variable V21 and embossing principal velocity controlled quentity controlled variable V31 in conjunction with feeding gearratio i2 and embossing gearratio i3.

V21＝V1xi2；V31＝V1xi3xKxD _min/D

Wherein D is the knurling rolls diameter, the K correction factor.

2) control of feeding motor.The closed-loop control system control that the control of embossing motor 14, feeding motor 13 is made up of tension pick-up 5.

Feeding tension force adopts PID control, PID adjuster principle:

$M\left(t\right)=\mathrm{Kc}\×e+\mathrm{Kc}{\∫}_0^t\mathrm{edt}+M_{\mathrm{initial}}+\mathrm{Kc}\×\frac{\mathrm{de}}{\mathrm{dt}}$

More than each the amount all be continuous quantity, first be proportional, last is a differential term, the centre two be the integration item.E is a loop errer; Kc is the gain of pid loop; Minitial is the initial value of pid loop output.

To the discrete periodic sampling deviation formula that turns to of above-mentioned formula, each signal is also wanted discretization simultaneously below, and discrete expression is:

$\mathrm{Mn}=K_c\&times;e_n+{\mathrm{<figure-callout\; id="1"\; label="K"\; filenames="Y2009200327940008H1.png"\; state="\{\{state\}\}">K</figure-callout>}}_1\underset{i=1}{\overset{n}{\mathrm{\&Sigma;}}}{e}_i+M_{\mathrm{initial}}+K_D\&times;(e_n-e_{n-1})$

Utilize the interative computation of Computer Processing, promptly can simplify above expression formula and be:

Mn＝K _c×e _n+K ₁×e _n+M _X+K _D×(e _n-e _n-1)

Following formula is made up simplification, can obtain formula:

Mn＝MP _n+MI _n+MD _n

MP _n＝K _c×(SP _n-PV _n)

MIn＝K _c×(T _S÷Ti)×(SPn-PVn)+M _X

MD _n＝K _c×(T _D÷T _S)×(PV _n-1-PV _n)

Mn, MPn, MIn, MDn are calculated value, proportional value, integration item value, the differential term value of n sampling instant.

PVn is a process variables in the following formula, SPn specified rate, Mn controlled quentity controlled variable, Kc proportional term gain, T _SBe the sampling time, Tl is an integration time constant, and TD is a derivative time constant, and MX is an integration item preceding paragraph, and PVn-1 is the process variable value of PID computing last time.

Kc is a proportionality coefficient, it is summary responses that ratio is regulated deviation e, deviation is in case produce, adjuster produces control action immediately makes controlled volume change towards the direction that reduces deviation, its effect power depends on Kc, Kc heightens as far as possible, and bigger Kc can make regulating loop not only soon but also accurate, but too high Kc value can cause overshoot even vibration (instability).

The effect of integration is to eliminate remaining static difference in the proportional controller, as long as deviation is non-vanishing, it will influence controlled quentity controlled variable by cumulative function, and in the hope of reducing deviation, when deviation was zero, controlled quentity controlled variable no longer changed, and system just can reach stable state.Tl is the time of integration, has reflected the power of controller integral action, and a little less than the big integral action of Tl, the little integral action of Tl is strong.

Differential is regulated and is worked when deviation changes, it is regulated according to the rate of change of deviation, deviation changes fast more, the differential controlled quentity controlled variable is big more, so on the basis of proportional action, increase the differential action degree of oscillation of the transitional processes of system will be reduced, the dynamic stability of raising system, the dynamic property of improvement system.But the differential action can not be too strong. be TD can not be too big. otherwise can cause system's thermal agitation too soon because of reaction speed.

3) control of embossing motor.The controlled quentity controlled variable V3 of embossing motor 14 is made up of embossing motor main control quantity V31 and embossing motor regulated quantity V32.V3＝V31+V32，

Wherein V32 is made up of the plus or minus stack regulated quantity that the manual adjustments button produces under manual state.The regulated quantity that the deviation of mark's wire tag that is detected by photoelectric sensor under auto state produces is formed.Control method is: after manual casing pressure puts, will overlap the flower button and get to auto state, and detect the angular displacement that mark's line begins more main motor version roller and knurling rolls from the first time, thereby produce corresponding positive and negative regulated quantity.The size of regulated quantity is set by man-machine interface.

Feeding of the present utility model and embossing electric device adopt high-precision encoder 2 to gather main motor speed, thereby realize high precision tracking.Feeding adopts tension pick-up 5 to detect PID control, thereby has guaranteed the stable of feeding tension force, for the embossing alignment is got ready.The cover flower adopts near switch 6 and 7 alignments of optoelectronic switch, then switches to auto state, carries out automatic casing pressure.Different versions knurling rolls directly change plate simple, only need to import the new edition diameter and get final product on man-machine interface 1, are undertaken sending instruction after the computing by main control module 10, control embossing motor 14,13 rotations of feeding motor respectively by motor module 12.The size of feeding tension force can be passed through man-machine interface setting range 0～500N.

Feeding of the present utility model and embossing device are simplified mechanical driving device greatly, have realized that automation precisely controls, and be simple in structure, the product plate change time shortens, reduce percent defective, made the synchronizing sleeve flower stable more, quick, accurate, improved productivity effect.
