1 Important aspects to improve conveyor performance 2008

2 Training 2008 Installation and Maintenance Replacement

3 Installation and Maintenance

4 Installation

5 Before installation please check the following parts –Wear strips (No glass or metal) –Drive sprockets and idler –Return part

6 Installation Catenary

7 Installing tabletop chains Important: –Running Direction –Mounting pins in plastic chains

8 Installing modular belts Important Note: Running direction is not important, only position of PosiTrack Are all clips in place?

9 Installing sprockets for modular belts Install sprockets with arrows in the same direction

10 Installation sprockets for modular belts Belts with PosiTrack> do not fix sprockets Belts without positrack> fix centre sprocket

11 Maintenance

12 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 ?

13 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 ?

14 Cleaning

15 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

16 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

17 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

18 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

19 Replacement

20 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

21 Replacing TableTop Chains If plate thickness is reduced to half of original plate thickness –Normal wear: –Uneven wear: –Wear of hinges: –Uneven wear:

22 Replacing Modular Chains Modular belt replacement: Maximum 3% elongation Thickness 50% of original thickness Belt is jumping on the sprockets Damaged end modules

23 Comparison old and new Positrack Design for Modular Chains Old Design (FTP or FGP Series) New Double Positrack Design (FTDP or FGDP Series)

24 Replacing Curves Magnetflex Curve Replacement

25 Replacing Curves - Curve Installation

26 Replacing Curves - Guide Shoe Position

27 Replacing Curves – Chainbelts (Series 105X and 1060)

28 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
