Sick ConVer quality control system

Errors and mistakes are an inevitable part of manual packing processes, which is why downstream completeness checks are essential to ensure product quality and customer satisfaction.

To have these quality control processes carried out by staff is expensive, time-consuming and often inconsistent. The ConVer quality control system from Sick checks whether boxes or containers have been filled correctly and include all the required contents.

The ConVer system comprises a scalable number of inspection stations that can be positioned along a belt wherever they are required. Each station is fitted with a Ranger E 3D vision sensor and a laser platform with six 2M lasers. The lasers generate a 1 m wide laser line that is powerful yet still safe for the eyes.

The Ranger E uses this laser to collect 3D information about the objects passing the sensor. This information is then compared in real time with reference images that have been taught-in previously. If any variance is detected, the system stops the belt straight away. Signal lamps and the monitor display guide the operator to quickly correct the packaging error.

ConVer is suitable for companies that offer a wide range of different products in either large or small batches as the product can be changed in seconds.

To teach-in reference images for the checking process, the packaged object is transported once through all stations of the packaging process and the operator sets parameters, such as characteristic features. The measurement data and images recorded by the system can also be used in subsequent systematic evaluations to identify any errors in the upstream production process that would otherwise remain undetected.
