Possible actuators are e.g. points, reversing stations or blow−
down nozzles which sort out the parts at certain positions on
the transporting device depending on the test result. The
number and assignment of the actuator positions may vary
depending on application. The assignment of the actuator
positions can be adapted with the CheckKon software.
Example of configuration Transporting device with
2blow−down nozzles (see Fig.1/1)
The compressed air valves of the blow−down positions must
be connected directly with the outputs for actuators 1...2.
These outputs are set to + 24 V DC if the parts test provides
the following result:
incorrectly−orientated or superfluous (good) part
bad or foreign part.
If the CHB−C−... recognizes a test part as good, the signal
actuator 3 will be set from open−circuit potential 0 V to + 24 V
DC and the good part will be output at the end of the trans
porting device.
Output Signal level 1) (example of configuration)
Actuator 1 There is a + 24 V DC signal when the test part
passes the actuator position for incorrectly−
orientated or superfluous good parts.
Actuator 2 There is a + 24 V DC signal when the test part
passes the actuator position for bad or foreign
parts.
Actuator 3 There is a + 24 V DC signal when the test part
passes the actuator position for good parts
(here: the end of the transporting device).
1) The duration of the signal correpsonds to the time required for
the part to reach the blow−down nozzle.
