Cabinet
3.2.2. Bin Full Sensor
To prevent commodity from overflowing the bins, each lower cabinet has a bin full sensor. If a sensor
detects that a bin is full, the machine stops collecting the commodity whose bin is full. If the machine
only collects one type of container, and its bin is full, the machine goes out of service and displays an
appropriate message. If the machine collects two or three types of containers, the machine continues to
function, collecting any containers whose bin is not full.
3.2.2.1. ULTRA 48 Bin Full Sensor
In the
ULTRA
48, the bin full sensor comprises an emitter and a receiver. These components are
attached to the side walls of the lower cabinet: the emitter is on the left, and the receiver is on
the right. When looking into the lower cabinet from the door (whether it is in the rear or the
front of the machine), the emitter and receiver are located towards the top rear of the cabinet.
Since the glass bins are shorter than the can and
PET
bins, a glass machine’s bin full sensor is
installed in a lower position than in the can and
PET
machines.
3.2.2.2. ULTRA HDS Bin Full Sensor
In the
ULTRA HDS
, the bin full sensor is an ultrasonic sensor that is installed in the top cabinet.
It faces the bottom of the commodity bins and measures the distance from the sensor to the
top of the pile of commodity. The software considers the commodity bin to be full if the top of
the pile is less than 12 inches (30 cm) away from the sensor.
3.2.3. ULTRA and ULTRA 48 Cabinets
The
ULTRA
and
ULTRA
48
RVM
s have two front doors: one on the bottom that covers the commodity
bins and one on the top. An access panel on the rear of the machine facilitates machine maintenance
and service. For safety reasons, sponsors and customers are not permitted to open the rear access panel.
The bottom of the cabinet features four levelers and four casters. The rear casters are fixed, and the front
casters swivel. Figure 3-3 shows the
ULTRA
48 cabinet and its components.
