Chapter 1: FT-70 System Overview
Triggering System
The Trigger System uses a fiber-optic light source to transmit a
light beam across the inspection tunnel to a receiver mounted on
the opposite side.
When a container passes through the beam, continuity is broken
and a container present state is created. The trigger initiates all
inspection activities, and in conjunction with the encoder provides
system timing for the rejector.
High Resolution Encoder
The High Resolution Encoder is calibrated to the conveyor speed
and container type, and provides timing pulses which the FT-70
uses to synchronize inspector and rejector activities. This allows
the microprocessor to track specific containers during inspection
and rejection regardless of the conveyor speed. The High
Resolution encoder is required for variable speed lines.
Rejection
The rejector removes all containers that fail inspection from the
production line. Timing for the rejector is provided by the encoder
and inspection trigger. This allows the conveyor to operate at
variable speeds without loss of rejection index timing.
For more information on the rejectors, see the rejector operation
manual that is included with your system.
Mounting
The FT-70 is mounted on a steel floor stand that is secured to the
floor. It will accommodate conveyor heights from 24 inches to 60
inches (61.5 cm to 153.8 cm). The floor stand height is specified
when you place your order.
Height Adjustment
A mechanical height adjustment mechanism provides 6.5 inches
(16.5 cm) of vertical adjustment to accommodate various container
heights. The height is displayed in a small counter on the front of
the FT-70 to provide adjustment measurement accuracy.
