Schubert is expanding its portfolio to meet the inline inspection task with a new standard module that performs several functions while also being easy to install, maintain and replace. “With this 600mm-wide unit, we are expanding our range of image processing systems to include a highly flexible option,” points out Daniel Greb, head of image processing at Gerhard Schubert. “We are specifically targeting manufacturers who are looking for an efficient, easy-to-use solution without having to compromise on the functional versatility of Schubert scanners.”

Today, not a single item exits the production line without having been rigorously inspected from all sides. This task is now rarely carried out by human eyes. With high throughput rates and stringent quality criteria, line scan cameras check the shape, colour and size of the products. They compare the results against predefined parameters. This provides a clear picture of the products, and a solid basis for decision-making regarding subsequent process steps.

The 600mm-wide module enables users to switch freely between 2D and 3D modes. The former checks products for surface characteristics such as shape, size and colour. The latter creates a three-dimensional image of the product and enables, for example, the precise measurement of volume and height, which are values that a simple ‘view from above’ cannot capture. The 3D function can detect complex quality characteristics, such as uneven fill levels, deformations or insufficient product quantities. In the generated image itself, variable colour values represent the differences in height.

The option to select between the two core methods offers flexibility when inspecting frequently changing goods. If a product requires a surface inspection or localisation, the 2D scanner is used. For more complex requirements, the 3D scanner takes over. “This not only saves time but also avoids an excess of costly and space-intensive technology within the production line,” adds Greb.

With the new generation of scanners, alignment is largely automated: a calibration template serves as the basis for a guided process that precisely aligns the optics and sensors. This eliminates the need for manual readjustment on each module. As a result, the process remains streamlined, and the technology is ready for use quickly after a new installation, without the need for extensive technical knowledge. The module reduces downtime and the need for human intervention to a minimum.
