5.12 Material Measurement sensor/Cutting sensor
Caution prior to inspecting the Material Measurement sensor/Cutting
sensor place the bar feeder into emergency stop.
The material measurement or cutting sensor is an input to the PLC. When material is moved
forward during the pre-feed bar change process, the end of the bar makes contact with a steel
flap. This flap is moved away from the cutting sensor and triggers the PLC to determine the
length of the bar based on the current pusher location. To reset the cutting Sensor flap back to
measuring positon a small throttle valve is used to push the flap back into position. This valve is
air controlled by the PLC.
The resetting of this device is important to proper bar change cycles. If the material gate is
unable to reset bar changes will not occur. Check for a bent flag or obstruction with the channel.
Note if the measurement sensor is in the wrong state of position, bar changes will not
The standard cutting sensor trip plate is designed for bar stock
larger than 2mm. If 2mm and smaller bar stock is to be used a
new trip plate may be obtained from Edge Technologies.
