Uneven loads on Roller Conveyors
Uneven loads on roller conveyors are difficuilt to be carried unless a roller conveyor is specially designed for that. While design of a Gravity Roller Conveyor or Powered Roller Conveyor, we use 3 or more rollers to make the product more stable. But in case of uneven loads it won't work.
We have to support the uneven portion by 3 rollers so that it wont topple. The even portion may get stuck in the gap between the rollers. To avoid this, we have to reduce the roller pitch to minimum possible according to the size of the uneven portion.
In the image below, the carton box is having concentric load at the arrow portion. This will make the box behave as shown.
