Functions
3.1.3 Sensor details
Sensor B1 "Pre-stop"
Sensor B2 and B3 "Sensing pallet route"
Sensor B2 and B3
Sensor B4 and B5 "Arm"
Function: Detects the arm position.
Sensor B4 and B5
Type: Proximity switch, inductive
Position: Placed together with Pre-stop.
Function: Detects the initiator plate of the pallet
before the pallet is stopped and stays active until
the pallet leaves the stop.
The reason why the pallet is detected by the
sensor before the pallet hits the stop, is to
enhance the efficiency of the pallet flow. As the
pallet is detected in advance, the controller has
time to take a decision whether or not the pallet
should be stopped. If it should pass, the stop
changes state to ”Release flow” before the pallet
reaches it.
Type: Photo eye.
Function: Detects if there is a pallet in the merging
area. A new pallet must not be released from any
of the stop positions before the merging area is
clear.
Type: Cylinder sensor
Position: Placed on the arm cylinder.
