Yuav ua li cas tswj kev nro thaum lub sij hawm siab -rewinding ceev kom tsis txhob wrinkling, sib txawv, los yog inconsistent nro?

Kev tswj nruj nruj yog qhov tseem ceeb ntawm kev nruj kom tsis txhob wrinkling, sib txawv los yog tsis sib xws thaum lub sij hawm siab - ceev winding. Nws yog ib qho tsim nyog kom ua tiav cov txiaj ntsig ruaj khov ntawm qhov nro los ntawm kev ua kom zoo ntawm cov khoom siv, kev tawm tswv yim hloov pauv thiab cov txheej txheem parameter txuam. Cov hauv qab no yog cov ntsiab lus tseem ceeb ntawm kev tswj hwm thiab kev siv cov tswv yim:

I. Cov ntsiab cai tseem ceeb ntawm kev tswj nruj
Lub ntsiab lus ntawm kev tswj nruj yog kom muaj lub zog tensile tas li ntawm cov khoom siv thaum lub sij hawm winding txheej txheem thiab tsis txhob deformation los yog hloov chaw ntawm cov khoom vim muaj kev sib hloov nro. Lub ntsiab logic yog:
Tension=winding torque/winding radius
Thaum lub sij hawm rewinding txheej txheem, lub rewinding vojvoog hloov tas li. Kev hloov pauv hauv lub vojvoog yuav tsum tau them nyiaj los ntawm kev hloov pauv hloov pauv ntawm lub zog winding (xws li lub cev muaj zog torque torque, braking force) lossis linear ceev (xws li kev sib kis loj) kom muaj kev ruaj ntseg ntawm kev nro.

II. Kev ntsuas tseem ceeb kom tsis txhob muaj wrinkles
Wrinkles feem ntau yog tshwm sim los ntawm qhov tsis muaj qhov nro lossis tsis sib xws hauv zos thiab yuav tsum tau tswj ntau txoj hauv kev:
Co-tsim ntawm coiling cov menyuam thiab cov menyuam
Cov menyuam siab: Siv lub siab sib xws los ntawm lub nruas los yog lub caij nplooj ntoos hlav kom paub meej tias cov khoom siv nruj rau lub nruas, tiv thaiv huab cua los ntawm ntxiab thiab ua rau wrinkles.
Cov khoom siv ntawm cov menyuam siab: Xaiv cov khoom nruab nrab elastic modulus (xws li roj hmab, polyurethane, thiab lwm yam), uas tuaj yeem muab siab txaus, tab sis kuj tuaj yeem hloov mus rau cov khoom me me tsis sib xws.
Txoj hauj lwm ntawm cov menyuam siab: Cov menyuam lub siab yuav tsum ncaj nraim saum toj lossis me ntsis ua ntej ntawm lub yob kom tiv thaiv cov khoom los ntawm sagging thiab wrinkling ua ntej nkag mus rau yob.
2.Tension yog tswj ntawm qhov hla ntu.
Thaj chaw nruj: Cov txheej txheem unwinding tau muab faib ua ntau qhov chaw (piv txwv li, unwinding, intermediate traction zone thiab unwinding), nrog rau cov nqi nro teem rau nws tus kheej nyob rau hauv txhua cheeb tsam los xyuas kom meej tias cov khoom ib tug stretched xeev nyob rau hauv tag nrho cov theem.
Taper nro tswj: Raws li lub coil txoj kab uas hla nce, qhov nro hauv cheeb tsam hauv cheeb tsam maj mam txo qis (los ntawm kev txo cov coil torque los yog ua kom lub coil nro) kom tiv thaiv cov khoom sab nraud los ntawm kev sib tsoo los ntawm compressing txheej sab hauv nrog ntau qhov nro.
3. Dynamic ceev sib piv
Main tsav thiab winding synchronization: Lub ntsiab tsav (xws li traction roller) thiab winding lub cev muaj zog yuav tsum tau kaw - voj ceev tswj los ntawm encoders los yog sensors los xyuas kom meej zoo linear ceev thiab zam cov khoom stretching los yog stacking vim ceev sib txawv.
Acceleration tswj: Thaum pib-nce, acceleration los yog deceleration, qhov ceev nkhaus yuav tsum tau kho kom zoo kom tsis txhob tam sim ntawd hloov ntawm nro los ntawm inertial cuam tshuam.

III. Cov tswv yim tseem ceeb los tiv thaiv kev sib txawv
Kev sib txawv yog tshwm sim los ntawm qhov tsis sib haum xeeb ntawm ob sab ntawm cov khoom siv lossis kev sib txawv ntawm lub kauj mechanism. Optimization yog xav tau nyob rau hauv cov hauv qab no:
Centering Device (Centering device)
Tsis siv neeg sib txawv kev kho qhov system: Lub ntug txoj hauj lwm ntawm cov khoom raug kuaj pom los ntawm photoelectric sensor los yog ultrasonic sensors, uas tsav deviation kho cov menyuam (xws li hluav taws xob los yog pneumatic deviation kho rollers) txav mus rau sab thiab kho cov khoom siv hauv lub sijhawm.
Tsim kev sib txawv ntawm kev kho cov menyuam: Lub qhov sib txawv ntawm qhov kev kho cov menyuam yuav tsum du kom tsis txhob khawb cov khoom. Txoj kev kho yuav tsum suav nrog qhov siab tshaj plaws ntawm cov khoom siv los xyuas kom muaj peev xwm kho tau txaus.
2. Kev tswj kom nruj
Kev ywj pheej hloov ntawm ob sab tensions: Tension sensors yog teem rau ntawm txhua sab ntawm cov khoom kom dynamically kho lub torque los yog tso nro ntawm ob lub windings los ntawm PID maub los los xyuas kom meej qhov nro ntawm ob sab.
Symmetrical tsim: lub installation txoj hauj lwm ntawm winding yob, siab rau cov menyuam thiab cov kev taw qhia cov menyuam yuav tsum nruj me ntsis symmetrical kom tsis txhob sib sib zog nqus tis ntawm nro vim mechanical deviation.
3. Kev ua kom zoo ntawm cov kev taw qhia rollers;
Qhia rau cov menyuam nto kev kho mob: kev qhia cov menyuam nto yuav tsum du, nto roughness yuav tsum tsis sib xws, txhawm rau tiv thaiv cov khoom hauv siab -kev ua haujlwm ceev vim muaj kev sib txhuam thiab sib txawv.
Qhia cov menyuam lub kaum sab xis hloov kho: los ntawm kev kho cov kev taw qhia cov menyuam lub kaum sab xis ntawm inclination (xws li winding lub kaum sab xis hloov), koj tuaj yeem hloov cov kev taw qhia ntawm cov khoom siv quab yuam, pab kho deviation.
Plaub. Cov kev daws teeb meem rau kev sib khi tsis sib xws
Kev nruj nruj feem ntau yog tshwm sim los ntawm kev sib hloov ntawm qhov nro lossis qhov tsis xws ntawm cov qauv winding thiab xav tau kev txhim kho hauv cov hauv qab no:
1. Optimization ntawm Winding roller qauv
Kev nruj ntawm cov menyuam winding: Cov menyuam winding yuav tsum muaj qhov nruj txaus los tiv thaiv kev sib hloov ntawm qhov nro los ntawm centrifugal quab yuam deformation thaum lub sij hawm siab - kev sib hloov ceev.
Roll deg kho: yob nto yuav tsum du, roughness uniformity, zam lub zos so vim kev sib txhuam.
Txoj kev centrifugation: centrifugation yuav tsum tau nruab rau hauv nruab nrab nrog cov menyuam winding kom tsis txhob muaj qhov cua eccentricity.
2. Nruas kaw - voj tswj
Tension sensor Cov lus teb: Nruab nro sensors (xws li ntab cov menyuam hom lossis hom ntsuas ntsuas) nyob rau hauv qhov chaw winding, saib xyuas tus nqi nro hauv lub sijhawm, thiab dynamically kho winding torque los yog tso nro los ntawm PLC lossis maub los.
PID parameter tuning: Kho PID maub los qhov sib piv, ib qho, thiab qhov sib txawv raws li cov khoom siv xws li elastic modulus thiab tuab kom ntseeg tau tias cov lus teb ceev nrooj tsis muaj overtuning.
3.Cov txheej txheem parameter txuam
Cov khoom siv hloov kho: Kho qhov pib tensioning tus nqi thiab taper tensioning nkhaus ntawm cov khoom raws li nws elastic modulus, thickness thiab nto roughness kom tsis txhob muaj kev sib txhuam vim cov khoom deformation.
Kev tswj kom nrawm nrawm: Hauv siab - nrawm nrawm, yuav tsum maj mam nce qhov nrawm kom tsis txhob muaj kev hloov pauv sai sai thiab ua rau muaj kev sib hloov ceev. Nyob rau tib lub sijhawm, txhawm rau xyuas kom meej tias qhov rewinding ceev thiab cov khoom ua haujlwm muaj peev xwm (xws li ziab ceev, txheej ceev, thiab lwm yam).
