Corrugated carton glue line effective control scheme continues

When the first stored image showed a hairline-like glue strip, Amcor's manager, John Singleton, saw that the high resolution of the vision system meant that there was only a difference between a very few rejects and a full semi-trailer return. "This means that we can completely rewrite the history of the packaging industry. After this 100% comprehensive inspection, why do we still need 3 (glue) strips? Why can't we have two or even one?" said Lee Dawson, Amcor's director of standards and environment. Think about how much it can save."

The DVT 630 vision sensor helps produce a better carton.

Process improvement

The causes of the above failures are random and have now been resolved, including:

* When the line is running at full speed, the glue strip is too thin and below the required thickness. The initial modification was to apply more pressure on the glue storage bag, and an improved pressure regulator was installed later.

* At the start and stop of the glue line, spattering will reduce the accuracy; after the glue of the glue is re-made, the problem is solved.

* Frequent skewing of the carton location; check the conveyor belt drive system.

* There is a batch of products because the glue viscosity exceeds the index results in a small amount of glue. The glue supplier solved this problem.

After finding these reasons, the defective rate was reduced to zero, eliminating the need for high-cost defective machinery. Dicker said, “Carton machines complete hundreds of tasks of different specifications every week. Most of them can automatically download their machine setup data from their production control systems. In many cases, because they are not synchronized with the actual running tasks, So that the incorrect glue setting data was downloaded, our detection system will immediately pick out the incorrect glue additions, saving resources and avoiding rework.”

Smofad's model, the SM-Vidmon1's glue detection system, can also be equipped with optical feature recognition, bar code reading, component positioning and high-speed detection devices required for robot operation.
