Today we are going to discuss how to track a belt on a roller or slider bed conveyor.
Using recommended safety gear, follow these steps for pre-tracking inspection.
Lockout-tagout prior to physical inspection.
Make sure the conveyor is level across the width and length of the unit. Adjust the supports as necessary.
Check to make sure the drive pulley, tail pulley, snub idlers and all return idlers are square with the conveyor bed.
Next, ensure the belt is routed correctly. You may reference your installation and maintenance manual for additional assistance with this.
Finally make sure the belt lacing has been installed correctly and the edges of both ends of the belt are in-line with each other.
Remove lock-out equipment and run the belt at least 7 cycles to see if the problem is corrected.
If the belt is still experiencing tracking issues, we will begin tracking the belt using the handle bar method.
Think of the snub idler as a set of handle bars on a bike. You are riding a bike going against the flow of the conveyor. Now “steer” the snub idler to track the belt. In this case, the belt is tracking to your left, so pull the idler’s right side to you by moving the idler clip and roller shaft in 1/8 inch increments. Continue moving the idler, “your handle bars”, until the belt appears to be tracking straight.
Allow the conveyor belt to cycle at least 7 times to notice a change in tracking.
You may have to repeat this step multiple times depending on the length of your conveyor and number of snub idlers.
When you are finished tracking all idlers, tighten the bolts in the idler clips.
You have now tracked a belt on Hytrol roller or slider bed conveyor.
