SPEDE Vision solutions also use Keyence vision sensors to prevent errors in identifying, counting, packing and labeling finished parts. When workers are new to a job, tired or distracted, they can confuse similar-looking parts and cause serious problems downstream for both customer and supplier.
Infrared or Visible Light Sensors? For part validation and counting, SPEDE uses Infrared vision sensors.
For color detection, or detection of color variations in parts, SPEDE uses Visible Light sensors.
SPEDE vision sensor solutions include these functions:
How a SPEDE Vision Sensor Solution works:
A Keyence vision sensor is "trained" to recognize a part number based on the unique characteristic of that part, using image capture and pixel analysis.
A SPEDE vision solution does not require a PLC to supply part number data. This means vision sensors can be used at Pack and Re-pack stations where no PLC is present, in addition to at the production machine if parts are packed there. A touchscreen PC will display an image of the part being scanned as the part passes under the sensor via conveyor, or is presented by hand. If SPEDE determines the part is correct, it will increment the count towards the pack count. If not, it can optionally trigger the part to be diverted via conveyor and increment a scrap count increase. An audio/visual signal will alert the operator of the exception to prevent the packing of wrong or scrap parts.
