Infeed Option
The bagger can be configured with an optional Infeed to automatically deliver product into the opened bag. The
device can be selected as a Filler The general Filling machine can take on many variations and is usually sup-
plied by another company.
Filler
This selects an independent, automated device that will deliver product to the Sharp bagger and can provide
digital I/O signaling to the bagger, i.e., bowl feeder, conveyor or weigh scale.
Filler Drop Time
Filler Drop Time is user adjustable time delay that provides a sufficient amount of time for the part to fall from the
filler device into the opened bag and past the pressure bar. It can be adjusted from 0 – 9.99 seconds. Typically
the bagger is setup to run in Auto Filler Mode, so that when the Filler Drop Timer expires, the next bagger cycle
will start.
Filler Handshaking Specification
This document is intended to be an agreement between Sharp Packaging Systems and parties that design and
manufacture equipment which will be interfacing with the Sharp product line. It describes multiple variations of
interfacing options. The interfacing option chosen will be application dependent.
Filler Definitions
Filler
: An independent, automated device that will deliver product to the Sharp bagger and can provide
digital I/O signaling to the bagger, i.e. bowl feeder, conveyor or weigh scale.
Intermittent Filler
: This type of filler is characterized by asynchronous cycling action. The filling ma-
chine will hold or manage its product until it is instructed by the Sharp Bagger to deliver the product. The timing
of the filler delivery is determined by the length of time between bagger cycles. Intermittent Fillers are only per-
mitted to deliver product between bagger cycles.
Examples of intermittent fillers include linear weigh scales, indexing infeed conveyors and bowl feeders.
Handshaking Signals Definition
O-13
-
Ready for Filler
: This is an output that signals the filling machine when the bagger is ready to ac-
cept product delivery. This signal must be continuously monitored by the filling device. The signal is presented
as a N.O. dry contact closure to provide electrical isolation between the two systems. The contacts will be closed
when O-13 is on and will open when O-13 is off.
Intermittent Applications
– O-13 cycles from OFF to ON with each bagger cycle. It goes HIGH when a bag has
been fed out into the filling position. It goes LOW if the bagger receives a valid I-11 Filler Trigger signal OR if the
bagger is faulted and unable to automatically cycle.
I-11 – Filler Trigger
: This is an input from the filling system telling the bagger that the filler has complet-
ed its product delivery. The bagger will provide a suitable drop delay to account for the last part clearing the bag-
ger funnel before cycling. The filler will present this signal to the bagger as a N.O. dry contact to ensure electri-
cal isolation between the two systems.
Filler Trigger
should be switched on immediately at the point in time when
product delivery is completed.
Intermittent Applications
– The Filler PLC program should reset I-11 Trigger Filler when it sees that O-13
Ready For Filler has transitioned from ON to OFF.
