Important aspects to improve conveyor performance

2. 2008 Training Installation and Maintenance Replacement

3. Installation and Maintenance

4. Installation

5. Installation • 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. Maintenance 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. Cleaning 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 <10 (weekly) Rare cleaning with pH >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. New: 20 links = 762mm Replace if : 20 links > 784mm Replacing Tabletop chains • Elongation • Maximum 3% elongation (762 mm > 784 mm) • Cause • Worn hinges • worn pins

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
