Qhov sib txawv tseem ceeb ntawm lub zog thiab tsis muaj zog rau cov menyuam conveyors yog nyob rau hauv yuav ua li cas lawv txav cov ntaub ntawv:
Powered Roller Conveyor:
Powered roller conveyors yog nruab nrog lub cev muaj zog lossis lwm qhov chaw ntawm lub zog uas tsav cov chais kom txav cov khoom raws li txoj kab conveyor.
Lawv tsim nyog rau kev thauj cov khoom hnyav dua lossis cov khoom siv ntev dua.
Powered roller conveyors muab kev tswj ntau dua ntawm kev ceev thiab kev taw qhia ntawm cov khoom raug xa tawm.
Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau ua haujlwm tas mus li lossis siv cov khoom siv, xws li hauv kev tsim khoom, chaw faib khoom, lossis cov tsev khaws khoom.
Variations ntawm powered roller conveyors muaj xws li lineshaft conveyors, siv-tsav conveyors, saw-driven conveyors, thiab motor-tsav roller conveyors.
Unpowered Roller Conveyor(Gravity Roller Conveyor):
Unpowered roller conveyors cia siab rau lub ntiajteb txawj nqus txav cov ntaub ntawv raws li txoj kab conveyor. Cov rollers feem ntau muab tso rau ntawm qhov qis me ntsis, cia lub ntiajteb txawj nqus rub cov ntaub ntawv los ntawm ib kawg mus rau lwm qhov.
Lawv yooj yim dua hauv kev tsim thiab tsis tas yuav tsum tau siv hluav taws xob sab nraud lossis lub cev muaj zog.
Unpowered roller conveyors yog qhov zoo tshaj plaws rau kev sib zog ua haujlwm lossis kev siv qhov chaw txav ntawm cov ntaub ntawv tuaj yeem pab los ntawm lub ntiajteb txawj nqus ib leeg.
Lawv feem ntau yog siv rau kev tuav cov khoom siv, xws li kev thauj khoom thiab tshem tawm cov tsheb thauj khoom, cais cov pob khoom, lossis thauj cov khoom hauv qhov chaw.
Txawm hais tias lawv tsis tshua muaj kev nyuaj thiab feem ntau tsis tshua kim tshaj li cov khoom siv hluav taws xob siv hluav taws xob, lawv muaj kev tswj xyuas tsawg dua ntawm kev ceev thiab kev taw qhia ntawm cov ntaub ntawv thiab tsis haum rau txhua hom kev siv.
