7.5. The Detection Belt
7.5.1. General
Schematic
The detection belt consists of a wide fl at belt (640 or 1200 mm) of a specifi c colour chosen in function of
the products to be sorted. It is driven by a reductor motor that rotates the drive drum (1). The upper part
of the belt runs from the drive drum over gliding plates (3) to the return station (4), and the lower part
goes straight back to the drive drum.
To keep the belt clean during the sorting process the system has been equipped with an optional water
spray system (6). To remove any sticky product or objects, an outside scraper (7) and a v-shaped inside
scraper (8) have been added. During operation one should regularly check that the scrapers - inside and
outside - really do touch the belt, but are not pressed too tightly against the belt (for this could damage
the belt and thus affect the sorting effi ciency).
The return station (4) may consist of a large or a small return axle. The choice of return station is
determined by the shape and the properties of the products that are to be sorted. Large or small return
axle makes absolutely no difference when tensing or tracking the detection belt. Keep in mind that the
return station is always fi xed to the frame, so any adjustments for tensing and/or tracking will have to be
done by adjusting the position of the drive drum.
If the GENIUS Compact sorter unit is equipped with a laser box, a background drum (5) will be added
to the confi guration.
General
Remember that correct tensing and tracking is very important for any kind of belt (including return system,
accept and/or reject belts). If the belt is under enough tension it will start slipping and will not function
properly. However, if it is under too much tension, this will damage and decrease the lifetime of not only
the belt itself, but also of the bearings of the belt system.
It is also important to regularly grease the bearings of all rotating elements, including drive drum, return
axles, background drums/reference rollers (laser box option), light tubes (FSV-option), etc... For more
info, check greasing procedure later in this chapter. The return axle of the detection belt is greased for
life and should not need any maintenance.
