Important aspects to improve conveyor performance 2008
Training 2008 Installation and Maintenance Replacement
Installation and Maintenance
Before installation please check the following parts –Wear strips (No glass or metal) –Drive sprockets and idler –Return part
Installing tabletop chains Important: –Running Direction –Mounting pins in plastic chains
Installing modular belts Important Note: Running direction is not important, only position of PosiTrack Are all clips in place?
Installing sprockets for modular belts Install sprockets with arrows in the same direction
Installation sprockets for modular belts Belts with PosiTrack> do not fix sprockets Belts without positrack> fix centre sprocket
Checklist Do the chains shown unusual wear patterns ? Is the chain surface still OK ? Is he elongation still acceptable ? Do the chains run smoothly? Is the adjustments of transfer and dead plates OK ? Are the sprockets still in proper condition ?
Maintenance Checklist Does the area around the sprockets collect a lot of dirt ? Are the sprockets fixed properly ? Are the wear strips still in proper conditions ? Does the lubrication system work properly ? Are the corner tracks still in good condition ? Do the chains shown any sign of chemical damage ? Is the catenary sag not to big ?
Improper cleaning will result in: Damage and dirt to products conveyed Increased chain load and motor load Increase of sprocket wear Increased wear of wear strips Sticking of chains to the sprockets
Cleaning Important aspects of cleaning Cleaning away of broken products Use warm water and soap Cleaning agent must be suitable with chain materials In lubrication agent, cleaning agent can be included
Cleaning Agents Consider the following : pH-value between 4 and 10 for stainless steel chains Neutral pH value for plastic chains Frequent cleaning only with pH > 7 and 4 and <6 (monthly with very good rinsing) no free chlorine no ammonium no phosphoric acid no halogenic agents
Cleaning Lubrication should be on top of the chain and underneath the chain At curves we recommend to lubricate the inside of the corners If the conveyor can not be lubricated during normal running, we recommend to lubricate during a stop By putting mineral oil on side flexing chain, the lifetime can be increased significantly Roller chains should be additionally lubricated before installation
Replacing Tabletop chains Elongation Maximum 3% elongation (762 mm > 784 mm) Cause –Worn hinges –worn pins New: 20 links = 762mm Replace if :20 links > 784mm
Replacing TableTop Chains If plate thickness is reduced to half of original plate thickness –Normal wear: –Uneven wear: –Wear of hinges: –Uneven wear:
Replacing Modular Chains Modular belt replacement: Maximum 3% elongation Thickness 50% of original thickness Belt is jumping on the sprockets Damaged end modules
Comparison old and new Positrack Design for Modular Chains Old Design (FTP or FGP Series) New Double Positrack Design (FTDP or FGDP Series)
Replacing Curves Magnetflex Curve Replacement
Replacing Curves - Curve Installation
Replacing Curves - Guide Shoe Position
Replacing Curves – Chainbelts (Series 105X and 1060)
Replacement of Components Wear Strips –Glass / metal has embedded in the wear strips –uneven wear Return Rollers –Glass or metal is embedded in the rollers –Do the rollers rotate Sprockets –If chain is replaced due to elongation –Damaged teeth
