Carton forming machines yog cov cuab yeej tseem ceeb ntawm kev lag luam ntim khoom, nws txoj haujlwm ruaj khov ncaj qha cuam tshuam rau kev tsim khoom thiab cov khoom zoo. Txawm li cas los xij, hauv cov txheej txheem tsim khoom tiag tiag, feem ntau cov ntawv jamming, ua rau cov khoom siv poob qis, cov ntaub ntawv pov tseg, kev txiav txim qeeb, thiab lwm yam. Daim ntawv no txheeb xyuas qhov ua rau ntawm daim ntawv jamming hauv lub thawv molding tshuab thiab tso rau pem hauv ntej cov kev daws teeb meem los muab kev siv rau kev lag luam practitioners.
I. Ua rau Paper Jamming
1.Cov khoom muaj feem xyuam
(1) Cov ntsiab lus tsis sib xws yog qhov tsis sib xws.
Daim ntawv noo noo cov ntsiab lus yog qhov tseem ceeb cuam tshuam rau molding zoo. Yog tias daim ntawv khaws cia rau hauv qhov chaw ntub dej, nws cov fibers nqus dej noo thiab nthuav dav, ua rau "curling" lossis "tight edges." Piv txwv li, tej yam kev mob qhuav tuaj yeem ua rau daim ntawv me me thiab ua rau nkig. Cov ntsiab lus tsis sib xws no tuaj yeem ua rau daim ntawv curl los yog deform thaum lub sij hawm thauj khoom, ua rau daim ntawv tau daig hauv pwm lossis cov khoom siv. Piv txwv li, lub tuam txhab ntim khoom siv damp corrugated cardboard rau peb hnub ua ke. Qhov teeb meem tau daws los ntawm kev hloov cov ntawv ntub dej thiab ntxiv cov khoom siv dehumidification rau lub tsev rau khoom.
(2) Kev taw qhia ntawm Daim Ntawv Fiber thiab cov kev taw qhia ntawm molding.
Daim ntawv fibers yog kev taw qhia. Yog hais tias qhov qhib kev taw qhia ntawm lub thawv yog sib npaug mus rau qhov kev taw qhia ntawm fiber ntau, qhov qhib qhib yuav bulge. Qhov no yog vim tias cov fibers deform thaum lawv nqus dej noo thaum luam ntawv thiab tuag- txiav, ua rau lub thawv nthuav tawm sab nraud thaum kho. Lub tuam txhab luam ntawv tau ntsib qhov teeb meem no thaum tsim cov thawv cawv. Los ntawm kev kho cov kev taw qhia layout, lub kaum sab xis ntawm cov kev taw qhia fiber ntau thiab cov kev taw qhia kev sib sau ncav cuag 45 degree, thiab cov teeb meem ntawm perforation bulge yog daws.
(3) Kev sib tw tsis txaus ntawm cov ntawv tuab thiab cov khoom siv.
Cov khoom sib txawv rau cov ntawv tuab muaj qhov sib txawv tshwj xeeb. Siv daim ntawv nyias dhau (piv txwv li, duab los qhia hauv qab 200 g / m2) yuav tsis muaj zog thiab yuav ua rau raug crushed los yog curled thaum thauj. Hloov pauv, daim ntawv uas tuab heev (piv txwv li, grey panels ntau dua 400 g / m2) tuaj yeem ua rau muaj teeb meem kev thauj mus los vim muaj kev sib txhuam ntau dhau. Ib lub tuam txhab ib zaug tsim khoom plig tawm lub thawv khoom plig g / m2 tshwj xeeb ntawm daim ntawv tshwj xeeb. Vim tias daim ntawv sib txhuam coefficient thiab cov khoom siv tsis sib xws, feem ntau cov ntawv jamming tshwm sim. Qhov teeb meem tau daws los ntawm kev hloov mus rau 300 g / m2 daim ntawv ntawm daim ntawv thiab kho lub siab ntawm lub nruas conveyor.
2. Cov khoom muaj feem cuam tshuam
(1) Conveyor System Failures
conveyor system yog ib qho chaw uas muaj ntawv thaiv. Cov teeb meem muaj xws li:
- Hnav Pub Cov Menyuam Yaus: Cov roj hmab saum npoo ntawm cov menyuam yuav hnav lub sijhawm, yog li txo kev sib txhuam thiab tiv thaiv kev sib cais ntawm ib daim ntawv. Ib lub tuam txhab tau txo cov ntawv txhaws los ntawm 15 feem pua mus rau 3 feem pua los ntawm kev hloov cov khoom noj txhua txhua rau lub hlis.
- Loose los yog misaligned Belts: Loose conveyor siv yuav ua rau daim ntawv plam los yog dislocation, thiab dislocated daim ntawv yuav yooj yim tau daig ntawm ntug ntawm pwm. Ib lub cuab yeej tau hloov kho dua tshiab nrog cov cuab yeej siv tensioning thiab photoelectric sensors los saib xyuas txoj haujlwm ntawm txoj siv sia nyob rau lub sijhawm, txo cov kev ua tsis tiav.
- Txoj Kev Qhia Rail Spacing tsis tsim nyog: Txoj kev nqaim dhau ntawm txoj kab tsheb ciav hlau tuaj yeem nthuav tawm daim ntawv, thiab qhov dav dav tuaj yeem ua rau muaj kev cuam tshuam. Ib lub tuam txhab tau kho cov lus qhia kev tsheb ciav hlau sib nrug mus rau daim ntawv dav + 2 hli, ntxiv cov lus qhia kho tau thiab txo cov ntawv jamming tus nqi los ntawm 40%.
(2) Tsim Flaws ntawm molding tuag.
Kev tsim pwm tsis zoo yog qhov ua rau muaj kev sib sib zog nqus ntawm daim ntawv jamming, xws li:
- Cov kab nrib pleb: Cov kab nrib pleb uas tsis tob txaus tiv thaiv kev sib cais ntawm cov fibers, ua kua muag lossis txhaws thaum lub sij hawm molding. Ib lub tuam txhab tau nce qhov tob ntawm cov kab nrib pleb los ntawm 0.3 hli mus rau 0.5 hli thiab siv laser tuag- txiav los txhim kho qhov tseeb thiab daws qhov txhaws ntawm sab ntawm lub thawv khoom plig.
- Lub kaum sab xis khoov tsis zoo: lub kaum sab xis me me dhau los ua rau daim ntawv khoov lub vojvoog, ua rau cov ntawv daig hauv cov kab pwm. Ib qho kev hloov kho rau ib qho khoom siv tau tsa lub kaum sab xis ntawm 60 degrees mus rau 90 degrees thiab ntxiv ib qho kev hloov pauv uas txo cov ntawv jamming tus nqi los ntawm 60%.
- Pwm nto ntxhib: khawb los yog burrs ntawm cov pwm tuaj yeem khawb daim ntawv, ua rau cov fibers tawg lossis lo. Ib lub tuam txhab tau txo cov ntawv congestion thiab pov tseg los ntawm tsis tu ncua polishing nto ntawm pwm thiab txheej lawv nrog nplaum.
(3) Sensor thiab tswj qhov tsis ua haujlwm
Sensors yog "qhov muag" uas cov cuab yeej ua haujlwm, thiab qhov tsis ua haujlwm ntawm lub sensor tuaj yeem ua rau kev txiav txim tsis zoo lossis kev tswj tsis tau:
- Contaminated Photoelectric Sensors: hmoov av los yog number case hmoov npog qhov chaw ntawm lub sensor tuaj yeem ua rau kev nyeem ntawv tsis raug ntawm txoj hauj lwm. Ib lub tuam txhab tau txo qis qhov ntsuas qhov tsis ua haujlwm los ntawm peb mus rau ib lub hlis, ntxiv cov khoom siv ntxuav lub cev xws li compressed cua tshuab- tshuab ziab khaub ncaws thiab siv cov txheej txheem kev ntxuav tes tsis tu ncua.
- Kev tswj qhov system tsis raug: Kev teeb tsa tsis raug, xws li qhov nrawm thiab siab ntawm cov khoom siv, tuaj yeem ua rau asynchronous txav ntawm daim ntawv thiab khoom siv. Ib lub tuam txhab tau tsim cov ntaub ntawv ntawm cov ntaub ntawv uas tau txais kev pom zoo raws li hom ntawv, txo cov ntawv jamming tus nqi los ntawm 50%.
3. Kev ua haujlwm thiab kev tu vaj tse
(1) Kev ua haujlwm tsis raug
Kev paub tus neeg ua haujlwm tsis txaus yog feem ntau ua rau daim ntawv jamming:
- Misplaced daim ntawv: piv txwv li, misaligned, ntau stacking los yog cov ntawv sib xyaw ntawm ntau qhov sib txawv nrog cov lus qhia. Ib lub tuam txhab txo cov ntawv cuam tshuam los ntawm 30% los ntawm kev cob qhia cov neeg ua haujlwm siv "peb - kauj ruam kev sib raug zoo" -- aiming ua ntej ntawm tus Tsov tus tw, tom qab ntawd ntawm sab, ces nias rau ntawm daim ntawv.
- Ua tsis tiav cov khoom pov tseg hauv lub sijhawm: Cov kab ntawv thiab cov kab xev khib nyiab tuaj yeem thaiv cov kab conveyor. Ib lub tuam txhab tau txo cov ntawv tsis sib xws thiab cov khoom siv ua tsis zoo los ntawm kev siv "5S Management" system (sorting, teem, polishing, standardizing, tswj) uas xav kom cov neeg ua haujlwm tshem tawm cov khib nyiab tom qab txhua txoj haujlwm.
(2) Kev kho tsis zoo
Kev siv sijhawm ntev - tuaj yeem ua rau hnav lossis plua plav ntawm cov khoom siv, ua rau kev ua haujlwm tsis zoo:
- Lubrication tsis txaus: Tsis muaj lubrication ntawm conveyor rollers, chains thiab lwm yam khoom tuaj yeem ua rau muaj kev sib txhuam, ua rau daim ntawv hlais lossis txhaws. Ib lub tuam txhab txuas ntxiv lub neej ntawm cov cuab yeej siv thiab txo qis cov ntawv jamming los ntawm kev tsim lub sijhawm lubrication (xws li, greasing txhua ob lub lis piam) thiab siv lub tshuab lubrication tsis siv neeg.
- Kev laus hluav taws xob Cheebtsam: Oxidized tiv tauj ntawm relays thiab contactors cuam tshuam cov teeb liab tswj. Ib lub tuam txhab tau txo qis hluav taws xob tsis ua hauj lwm los ntawm tsib zaug hauv ib hlis mus rau ib zaug los ntawm kev soj ntsuam cov hluav taws xob tsis tu ncua rau kev tiv thaiv thiab hloov cov khoom qub.
