Preventive Maintenance Tips for Product Handling Conveyors

Preventive maintenance of conveyors is necessary to avoid unwanted interruptions, caused by failures or malfunctions, which would block the transport of materials along machinery.

MAINTENANCE CONSIDERATIONS

Avoid misusing conveyors.

Monitor belt tracking closely.

Know how to properly lubricate bearings.

Proper installation is a must.

Clean and check photo eyes.

Avoid under sizing pneumatic controlled devices.

Avoid water build-up in air lines.

Make sure conveyor systems are properly grounded.

Check chain and belt tension regularly.

Follow a Comprehensive Maintenance Plan

A comprehensive Preventative Maintenance Plan will convert to the highest possible levels of up-time for your packaging line. Initiate check lists and have the discipline for all maintenance personnel to use them.

Train your maintenance personnel on what the sounds and sights are for strained components, as well as how to properly test components.

Record equipment deterioration so parts can be replaced or repaired before they cause system failure.

Schedule regular maintenance and plan for outages when necessary. In a 24/7/365 factory, it may be necessary to plan weekly walk-arounds, with an outage scheduled every two months for stripping out the conveyor for cleaning and giving more thorough checks to the conveyor drives.

Clean Conveyors Regularly

The proper cleaning of conveyors and belts in a timely manner is important to the longevity of the belts and wear-strips. Regular cleaning maintenance procedures can also prevent product conveying issues.

Lack of proper cleaning has been the most contributing factor in Nercon service calls to determine conveying issues and performance.

Monitor Chain Tension

Inaccurate chain and belt tension is one of the top reasons for performance and wear related issues for conveyor belting, plastic chain and wear strips. It can be directly related to excessive wear and premature replacement of conveyor belting and chain.

. Routine inspection is a must to assure performance and longevity of the conveying surface.

Be sure to Ground Conveyor Systems Properly

Proper and assured grounding of the conveying system and all of the components is critically important to the proper operation and longevity of the conveyor system.

Many times our services team see instances of stray and induced voltages that are guilty of causing numerous functional and operational issues in installed conveyor systems. These are most often noticeable in frequency controllers and PLC’s but not limited to them as other individual devices can be affected as well.

Proper inspection and testing as part of a Preventative Maintenance (PM) program is important to confirm and assure the systems continued grounding integrity.

Give attention to Photo Eye Cleaning and Electrical Components

Another preventative maintenance issue that is often over looked is proper and timely cleaning of photo electric controls, targets and other electrical control components on the conveying line.

Routine visual inspections can identify issues before they lead to damage, down time and unnecessary replacement requirements.

Make sure the System is Properly Installed

Improper installation is probably the leading cause of operational issues and poor overall performance of the conveyor system.

m. Proper installation is the best assurance of long term performance and reliability of the conveying system. Misalignment of conveyors, interference with other equipment or devices, and incorrect placement of secondary devices that interfere with conveyor belt operation are all examples of poor installation.

Bearings must be Properly Lubricated

Proper lubrication of bearings is another preventative maintenance issue that is quite prevalent in many conveyor systems.

The proper type of lubricant and the proper amount are equally important maintenance issues. Many times Nercon service technicians see conveyors with bearings that are either over or under lubricated, neither of which is good for the bearing.

. Following the manufacturers recommended guidelines is important to achieve the proper operation and lifespan of bearings.

Provide Proper Tracking for Belt Conveyors

Belt conveyors should be visually inspected at minimum every shift. Often times there are many environmental issues as well as product issues that have the potential for adversely affecting the tracking of belts and potentially leading to unnecessary down time and repair or replacement costs.

Avoid Misuse of Conveyors

Placing heavier and larger objects on a lighter duty conveyor system will add stress and wear to not only the chain and wear strips, but also the motors and reducers — which will eventually result in a breakdown.

When repurposing conveyors, take the conveyor’s belt pull rating and horsepower requirements into consideration before increasing it’s workload.
