4.1 Functionality of the device
Compartment fine positioning is used for the detection of so-called hole positions (hole or reflector) that
are set into crossbeams of the high rack.
• Two different hole positions can be detected,
Rack Near
and
Rack Far
.
A check program is stored on the device for each detection position.
The distance between the rack profiles and the lens cover of the device can be specified for each
hole position.
• The control uses a signal that is constantly applied at digital switching inputs IO2 and IO3 to deter -
mine which check program is active; see chapter 4.4 "Process sequence".
4.2 Check programs
The
Rack Near
and
Rack Far
check programs detect the respective hole position. A BLOB tool and a
measuring tool in the check program are used for this purpose.
• With activation, compartment fine positioning for the
Rack Near
or
Rack Far
check program is
started or stopped via digital switching input I01.
Figure 4.1: Display of the detected hole position
• Digital switching outputs IO5 … IO8 signal whether the device is within the scan area for Rack Near
or Rack Far in relation to the hole position. Whether or not compartment fine positioning is correct or
whether the high-bay storage device is positioned too far to the left or right and/or too far up or down
relative to the hole position is displayed.
Figure 4.2: Switching outputs IO5 … IO8 activated
Digital switching outputs IO5 … IO8 are permanently on as long as the control performs compart -
ment fine positioning via the device.
• To compensate for the difference in position between loading position and unloading position of the
high-bay storage device, a shift of the coordinate origin is defined for the current check program by
entering an offset value.
On delivery, two check programs are set up in the device for
Rack Near
and
Rack Far
. These check
programs are optimized as follows:
•
Rack Near
Distance: 450 mm
Hole diameter: 15 mm
•
Rack Far
Distance: 1850 mm
Hole diameter: 15 mm
