Applications - Bottling and Canning - Mounts directly on Krones Labeling Equipment

PC-Eyebot can be effectively uses for 360 degree wraparound inspection of containers and labels for bottling and canning lines. Sightech's equipment can be mounted directly on popular Krones labeling equipment to allow three rotational views, all with only on camera! The ability to define multiple inspection Areas, assign frame delays, and to apply sophisticated decision consolidation allows all of the defined views (Areas) to result in a single PASS/FAIL decision per can or bottle.

 

The following example shows the ease of setup, training, and operation as well as the high degree of inspection ability.

 

PC-Eyebot can easily detect for the following 8 conditions:
1) dents, 2) up/down label shifts, 3) wraparound label uneven overlaps,
4) missing labels, 5) torn labels, 6) glue problems, 7)end flaps, and 8) wrong labels
.

If you want the best inspection for Krones equipment, be sure to contact Sightech Vision Systems!

can label wraparound inspection 360 degrees works with Krones equipment
Running: The image (above) shows detecting improper label shift, uneven overlap, and three different examples of dents in action. We have drastically slowed down the frame rate - we can operate at high container production speeds of 1400ppm if needed. Often, such lines will run from 200 to 600 PPM The desire to only produce the utmost in quality, automated inspection for a range of potential defects is important. PC-Eyebot offers the benefits of easy setup, intuitive operation, and powerful full-speed inspection ability. (above)

Step 1 - Setup: Place four Areas - one to inspect each container of three separate container view in the image, and one to inspect the center container's label overlap. (above). This arrangement allows 360 degree wraparound inspection with only one camera.

Step 2 - Learn: Simultaneously train all Areas on several good containers. Training is very easy to perform and normally 5 to 60 seconds is all that is required. Sightech can configure an external "Learn" button that can be accessed by the operators without directly controlling the system. When training is needed, the operator can just push the button. (above)
Step 3 Run: Running in Inspect mode, his example, (above), shows a PASS condition. The containers show no defects. The (above) image shows a dent in the center container view. The purple markup shows where the dent is. This is a FAIL condition.
The (above) image shows a misaligned label on the left container view. The purple markup shows where the defect is detected. This is a FAIL condition. The (above) image shows a wraparound label overlap misalignment. By dedicating a separate Area for this inspection task, you can set the decision sensitivity separately for this type of defect detection.
We have shown several impressive and important points:
1) Wraparound 360 degree inspection of containers for the bottling and canning industry.
2) Mounted the inspection system directly on Krones labeling equipment..
3) Using proprietary frame-delay technology, Sightech can consolidate decision results from 4 separate Areas so the ejection action always refers to the same can!
4) Sightech's self-learning technology lends itself well to Krones-based applications.
5) Line change-over's and product variance are easily accommodated due to a simple start-from-scratch or cumulative training function.
6) Additionally, PC-Eyebot has an option that can save up to 20,000 images of failed containers! These images can be accessed over ethernet from a remote location as well.
