12.
Start the conveyor and adjust it to the speed it will run at
during production. It is important that the chain run smoothly
to obtain accurate calibration.
Fine Tuning the Rejector Timing
To fine-tune the calibration accuracy you may need to adjust the
Millimeter Translation Value estimated during the Millimeter
Calibration Routine. Experiment with a production container and
observe the rejector timing. Based on where the rejector pad
contacts the container, you must increase or decrease the value
until the can contacts the pad correctly.
13.
Press Key 4 until REJECT NEXT appears and then press the
Arrow Key to enter the number of containers you want to reject
consecutively. Choose a number such as 6 or higher to provide
enough attempts to make adjustments. When the number
reaches zero, you must repeat this step to reactivate the
rejector.
14.
Press Key 5 until MILLIMETER TRANSLATION VALUE
appears.
15.
Spread a light film of grease across the face of the rejector pad.
The container will leave a mark in the grease at the point it
contacts the pad thereby making it easier for you to see where
the contact is occurring.
16.
With the conveyor running at production speed, place a
production container (preferably the container measured for
the Can Width At Trig value) upstream of the FT-50 so that it
passes through the FT-50 without slipping and is rejected by
the rejector.
17.
Examine the marking in the grease. If your calibration
procedure was accurate, the mark will be close to the center of
the pad. If the mark is off, adjust the Millimeter Translation
Value as follows:
•
If the rejector fired late (the mark is in the downstream
third of the rejector pad), decrease the millimeter trans-
lation value by 2.
•
If the rejector fired early (the mark is in the upstream third
of the rejector pad), increase the millimeter translation
value by 2.
18.
Repeat steps 16 and 17 until the rejector is contacting the cans
directly on the centerline of the pad.
