Physical Space
In some cases the addition of inspection options that require an
upstream or downstream trigger can change spacing requirements.
In these instances you should also review the requirements for
each option.
Conveyor System
The following conveyor requirements are designed to achieve
maximum inspection performance.
The rejector’s conveyor requirements, especially the Servotec’s, are
more critical than the FT-70’s requirements. When determining the
conveyor requirements it is imperative that you include the
rejector’s conveyor requirements. For the rejector’s conveyor
requirements refer to the rejector manual included with your
FT-70.
Production Conveyor
• A minimum chain velocity of zero (chain may stop without
losing synchronization) to a maximum chain velocity of 350
feet per minute (107 meters per minute).
• The conveyor must be capable of soft start-up . This means the
conveyor can gradually accelerate from a full stop to
production speed. This prevents containers from sliding and
upsetting on the chain.
• The conveyor chain must run smoothly during its passage
through the inspection and rejection area. Conveyor motion
that produces excessive foam or contents motion, or creates
slipping on the conveyor can decrease the accuracy of the fill
level inspection or interfere with rejection.
• IDC recommends that all conveyor chain wear strips in the
inspection and rejection areas be attached only on the upstream
end. This insures that when the wear strips thermally expand
they will not cause the chain to bow upward and effect the
inspection and rejection areas.
• The conveyor side channel must be at least 5 inches (12.6 cm)
tall in order to mount the rejector.
When determining the physical spacing requirements, you
must also consider the spacing requirements for the
rejector. Refer to the
FT-50 and FT-70 Installation and
Service Drawing Pack for an overview of the space
requirements.
