LabelScan

Typical applications include direct mounting in roll fed and sheet fed rotary labelers where the LabelScan will inspect each container:

to confirm that the proper label has been applied
to detect any container with a missing label
to inspect each label for tears, ripples and irregular applications
to measure minimum skew at lap point

Precision

LabelScan "learns" the proper label and location by assembling a statistical model of the target and then comparing each picture to the model. At the option of the user, LabelScan can eject products with extremely small differences or an acceptable amount of leniency.

Control

LabelScan inspection can be targeted on specific parts of the labeled package by defining the appropriate "regions of interest (ROI)." In addition, a tolerance setting enables smaller defects to be either accepted or rejected by the user.

Changeover

LabelScan stores multiple configurations from prior label runs for the same label. Each of these configurations can be easily accessed as a new run of an old labeled product commences. If differences require ther creation of a new model, LabelScan can assemble a new model in seconds.

Ejector / diverter options

LabelScan can be configured to interface with existing ejectors or work with the full range of Peco ejectors such as the high speed EJH-ST or the unique SlimLine flexible rail system .

Versatile

LabelScan’s single camera system frequently provides full circumference inspection of round containers by dividing each camera shot into multiple images and processing each separately. Optional multiple camera configurations allow for front and back inspection.

Ejector control

LabelScan includes Peco’s Multi-Trac ejector control system that assures accurate tracking of the mislabeled container from the discharge of the labeler to the ejector.

Easy to operate

Setup

With proper lighting, the inspection region of interest is defined by setting of the rectangular inspection area. As shown, multiple images can be taken from the same camera and used for independent analysis.

Learn

Once setup, the LabelScan will capture a sequence of images from the defined region of interest. The number of images varies with the repeatability of the container image and the degree of precision required for the application.

Run

Once the image is learned and the inspection resolution criteria selected, the LabelScan will inspect each container and signal for reject any containers whose image varies from the "good" learned image by a user-controlled degree of variation.
