SECTION 1 - INTRODUCTION
THEORY OF OPERATION
Ready for Filler (O:3/00) - The bagger PLC (Programmable Logic Controller) turns on this output as follows:
1. The machine has successfully completed a cycle and presented a new bag.
2. If the bagger is equipped with a positive entry funnel.
• The funnel is opened
3. If the bagger is equipped with a positive entry funnel AND “Bag Opened” Sensor (s):
• The funnel is opened
• The sensor detects that the bag is positively opened.
Once the above condition (s) is (are) met the PLC program turns on O:3/00, essentially telling the Filler device
that a bag is present and ready to be filled. The filling device releases its product into the open bag.
Filler Done (I:2/00) - The Filler device will turn on the bagger PLC input I:2/00
This signals the bagger that the filler has completed delivery of the product. The filler machine must include a dry
contact isolation relay for its signaling device to ensure electrical isolation between the Filler and the Bagger
PLC.
The filler function has a separate detailed specification, “Sharp Packaging Filler Handshaking”. The specification
covers all Sharp Baggers and includes signature sign-off lines so that Filling machine vendors are in 100% com-
pliance with this specification. This also ensures proper operation of a complete system.
AUTO MODE
Filler = OFF
Auto = ON
With Filler OFF and Auto ON, the bagger will run in “Auto Mode”. In Auto Mode the machine operator manually
fills the opened bag, while the machine cycles automatically. The cycle is started by means of a time delay
called the “Auto Dwell Timer”. This allows the bagger machine to be self paced, when production rates are criti-
cal. The Auto Dwell timer allows the operator time to manually drop product into the open bag. When the time
delay is ended the bag is sealed and the next bag is fed out. The Load Dwell time is adjustable at the HMI.
The operator initiates the first bag out and Auto Mode is immediately activated. When the bag is opened, the
operator loads the bag (Load Dwell Timer is timing). When the timer finishes, the bagger automatically starts the
bagger sealing cycle and feeds out the next bag. To cancel Auto Mode, the operator can press the Stop Button
on the HMI.
