iVu TG Image Sensor Zooms in for Reliable Small Part Inspection in Tough Location
A large-scale brewing company brews and bottles many popular and well known brands of beer in regional breweries throughout the United States. The company uses high-capacity rotary fillers to keep pace with the demand for their products.
The rotary fillers dispense beer into bottles traveling at speeds of up to 900 bottles per minute. Periodically a spreader washer and/or a vent tube may become loose and drop into a bottle or onto the line. Beer will continue to dispense but the bottles will not fill correctly and product will be wasted. If undetected, affected bottles may be capped, packaged and even shipped. These products will have to be recalled.
The company needed a solution capable of detecting spreader washers on the vent tubes as well as loose or missing tubes. However, the movement of the rotary filler and the wet wash-down environment made close proximity deployments difficult and the range required for a remote solution could compromise inspection reliability.
The company installed an iVu TG at target level 32″ from the target. Two air knives protect the iVu from spray and prevent associated interference. A 50mm C-Mount lens with extender lengthens the sensor’s working distance. This allows the company to deploy the sensor away from the target while providing the solution needed to detect loose or missing vent tubes as well as missing spreader washers.
Configured as an Area sensor, the iVu TG inspects for spreader washer and vent tube location and presence within 16 milliseconds. The operator defines the region of interest using the remote touch screen. If a washer drops below the region – indicating a loose tube – or if the washer or tube is missing, the single powered I/O will shut off the filler. The operator can then remove any affected product, correct the problem and get the filler working again with minimal downtime.
