Troubleshooting - Wedgemaster belt skipping

Applies to	VLF Trendsetter AL

Machines affected	All machines.

Error Number	None

Component	Picker - Wedgemaster

Problem	We have been having problems with the belts on the wedgemaster skipping because they are too loose.

Causes and Solutions	Cause: Several machines in the field have had the belts skip causing the slip sheet picking to fail. Solution: Page 6 of Dwg 50-1743 contains the assembly drawing showing the procedure used in production to adjust the belt tension. This procedure requires the use of a force gauge. The belt must be tight enough that it will never skip. If you do not have a force gauge, you can rotate the cups forcibly by hand against the force of the cylinder. This is the maximum load the belts will ever experience. The belt must not skip or be on the verge of skipping under this condition. Conversely they must not be too tight or it will make the mechanism too hard too turn or move smoothly. If the belt has skipped you will have to skip it back to the correct position. On page 7 is the procedure for adjusting the endpoints of the icup and ocup.
