A.5b Exit Conveyor
The Exit Conveyor is located at the output end of the folder. The mailers
exiting the folder are shingle stacked on the Exit Conveyor. As each mailer
exits the folder it passes through the discharge sensor, causing a signal to be
registered at the CPU. The CPU then sends a pulse to the Exit Conveyor and
the Exit Conveyor moves forward. When the machine is continuously cycling,
the Exit Conveyor is continuously running.
A.5c Sensor Input
With the folder and transfer conveyor running, touching the “FEED”+”ON” will turn
on the feed clutch. The feed clutch remains on until the feed sensor sees the leading
edge of a sheet.
If the leading edge of the paper is not seen after one rotation of the clutch, a “FEED”
alarm is declared.
Once the feed sensor sees the leading edge of the paper, the batch -count decrements
and the resettable total counts increment. Then the PLC checks if the batch count
number has been reached or the M-40 is single sheet cycling. If either case is true,
the feeding process is stopped and the feed clutch is shut off. Otherwise, the PLC
checks if continuous or noncontinuous feeding is selected. If noncontinuous feeding
is selected, the feed clutch is shut off.
While the sheet passes under the double detect sensor, the voltage values received
from the feed sensor are averaged to keep a nominal value of the paper’s thickness.
If a double feed occurs, the feed sensor voltage value will be less than one half of
this running average. If the feed sensor voltage is less than one half the average feed
sensor voltage for one time, the CPU declares a “DBL FEED” alarm.
The feed sensor signals the glue gun tips sealers to open when the first sheet of paper
passes through.
The sheet length is also monitored as it passes under the feed sensor. If the sheet is
under the feed sensor for more than a calculated distance of conveyor belt travel
(three inches plus the sheet size), a “DBL FEED” alarm is declared.
IMPORTANT!
Z-Fold, Four Plate Setup Only
To prevent possible Z-fold jams, make sure the Stripper Plate is mounted as
shown below. With the Stripper Plate adjacent to the perforating cutter wheel,
Z-fold documents will not tend to rise with the cutter blade.
