Description
The Allen-Bradley 45PVA is a photoelectric Parts Verification
Array designed for bin picking applications and object
detection in the parts assembly industry. When used as part of
a suitably configured bin-picking system, the 45PVA effectively
prevents mispicks to enhance efficiency and minimize down
time. It is also the ideal solution to address the “error proofing”
initiatives prevalent in the automotive industry.
The 45PVA uses an array of LEDs to create a light screen that
can be spanned across bins at an assembly station. By
mounting the sensors on parts bins and wiring them into a
controller programmed with the necessary logic, a virtually
error-free bin-picking process can be achieved. ‘Job lights’ on
the 45PVA will not only show the assembler the bins required
to complete the current process, but will also indicate the
correct picking sequence. In the event the assembler attempts
to pick an incorrect part, a selectable warning light on the
45PVA will illuminate to indicate the error; additional fault
enunciation can be achieved via controller logic in conjunction
with a tower light or audible alarm.
In addition to increasing efficiency and quality control by
preventing faults in the bin-picking process, the 45PVA is
instrumental in personnel stress reduction and the
simplification of personnel training—especially in multi-lingual
facilities.
