Dispenser Motor
and Transport
1
The spray presenter is supplied with either a 120 V or 240 V
induction type motor. This motor drives the presenter transport and
also, via toothed timing belts and gear trains, the transports and
pick arms of the pick modules. It also powers the pick vacuum
system.
In the presenter transport the bills are gripped between an upper
and a lower belt and driven through plastic guides to the dispenser
exit.
Main Timing Disk
1
The main timing disk is incorporated in the presenter transport
attached to the LVDT reference wheel shaft. The beam of an opto-
electronic sensor is chopped by the segments of the disk to create
timing pulses. These timing pulses are used to measure the
movement of the bills and as a reference in the measurement of bill
width. The interval between each pulse represents a distance
travelled by the bill of approximately 2 mm.
Linear Variable
Displacement
Transducer (LVDT)
1
The term “singularity” describes the parameters used by the
dispenser to recognize a single currency bill. In the 5635 dispenser
the detection of singularity of the currency is related to the cross-
sectional area of the bills. This is measured by the Linear Variable
Displacement Transducer assembly shown in the illustration below.
