This document provides information on automatic conveyor systems, including sections on system maintenance, belt maintenance, and the anatomy of a belt. It discusses the importance of frame precision for proper functioning of components. Key points of system maintenance include regular cleaning and inspection of rollers, pulleys, belts, splices and sidewalls. Belt tracking, tension, and proper installation are addressed in the belt maintenance section. The anatomy section defines terms like working tension, bottom belt covers, and the factors considered in belt selection like pulley diameter and system configuration. Automating conveyor switching using sensors is also mentioned.

1. AUTOMATIC CONVEYOR
SYSTEMS

2. Theory
 System Maintenance
 Belt Maintenance
 Anatomy of a belt

3. Section I: System Maintenance

4. Considerable Point
 A conveyor system frame is like a car frame, if your frame is not
precise it will throw off other components, creating wear and tear.

5. Cleaning
• Good system maintenance can be summed up in two
words, “Good Housekeeping”.
• Check pulleys and rollers for material build-up.

6. TO-DO LIST!
 Visually inspect:
 Rollers, Pulleys, Return rollers & belt
guides for excessive wear, built up
material and damage.
 Belt Splice for wear on lace, cracks,
missing components.
 Sidewall for damage and missing sections
 Inspect belts:
 Tracking properly
 Tension

7. Section II: Belt Maintenance

8. Belt Tracking/Training Considerations
 Conveyor belt moves toward the end of the roller/idler it contacts first
 Check conveyor system for structural misalignments
 Check pulleys and idlers for misalignment and material build-up
 Check belt splice for accuracy and straightness
 Observe belt in operation empty and loaded for tracking tendencies
 Eliminate Spillage, Off-center loading and build-up of materials, factors that
cause tracking issues

9. What happens if I install the wrong belt spec?
 Belt will wear faster than expected
 Belt may potentially fail
 Cleats and/or Sidewall may separate
from belt

10. Section III: Anatomy of a belt

11. Working Tension
 Working tension is a factor of the fabric/ply
 Rated on a per inch width
 Fabric strength has a direct impact on minimum pulley diameter
requirements
Why does it matter?
 Belt can snap in operation if not rated for the tension of the system

12. Bottom Cover of a Conveyor Belt
 May have a rubber bottom or a “bare-back” bottom
 PVC belts are:
 COS = Cover one Side
 CBS = Cover both sides
 Rubber Belts are:
 Called out by actual thickness of cover materials

13. What is a “Bare-Back”?
 A conveyor belt with no bottom rubber cover
 Bottom of conveyor belt is the fabric from the bottom ply
Why use a “Bare-Back”?
 Slider Bed Applications
 Fabric bottom has a lower coefficient of friction than a Rubber bottom

14. How do I know what belt to use?
 Belt selection is based on;
 Minimum pulley diameter
 The configuration of the conveyor system including;
 Type & Style of return
 Incline
 Changes in incline
 Slider bed or troughed rollers
 Overall length
 Height of incline
 Weight of material

15. Solar Power
 A solar panel is a set of solar photovoltaic modules electrically connected
and mounted on a supporting structure. A photovoltaic module is a
packaged, connected assembly of solar cells.

16. Automation Part
In this part we will make conveyer switching
automatic. As sensor senses some object on the
conveyer, it will get start.
As object will get downfall from conveyer it will get
stop.
