Vision sensors know the drill

German machine builder Schuster-Prazision uses Cognex vision systems as a robust and innovative component to make the difference on its sorting machines.

As a manufacturer of special machines, Schuster-Prazision in Germany ensures that its customers can assure the smooth running of various processes such as sorting, turning, milling and cutting parts to the correct length.

Quality assurance and automation technology are of the highest priority.

When it comes to the sorting of large numbers of parts, it is essential that the systems performing the task are completely reliable and capable of enduring the rigours of continuous operation.

One of the most important components of these special machines is the In-Sight vision system from Cognex.

For example, one of Schuster's largest customers, which manufactures 180,000 drill pieces per day, can count on 100% accurate sorting thanks to these precise sensors.

In the first step of the sorting process, the container of the machine which is equipped with an In-Sight 5100 from Cognex, is filled with several thousand drill components.

A sliding mechanism then moves the individual pieces down a ramp and onto a conveyor line.

The In-Sight and a special gripper ensure that the heads of the drill bits point in the correct direction.

With its precise sensors, the system detects the positions of the parts and transfers this information to the container's microprocessor.

If a drill component is positioned correctly, it is simply transported further on towards the output area.

If a drill piece is not positioned correctly however, the In-Sight informs the gripper, which grabs it and positions it correctly so it can continue to the output area with the other pieces.

This is a simple process but it requires reliable machine components because of the large numbers of parts being processed.

As in many other areas of the metal processing industry, machines must be robust in order to achieve the required precision, reliability and to operate round-the-clock.

The vibrations caused by mechanical conveyors, jolts from pneumatic systems and the dust in the production areas present quite a challenge to precision machinery.

Vision systems from Cognex are built to be particularly robust so that quality standards are always maintained, even under the most difficult conditions.

Equipped with die cast housings, lens protectors and M12 connectors with seals, they can withstand even the roughest industrial environments.

Today, the In-Sight 5000 family is indispensable for Schuster-Prazision because it guarantees high-quality production systems.

General Manager and company founder Helmut Schuster can no longer imagine his special machines without Cognex systems: "With Cognex, complete reliability, innovative technologies and excellent service allow us to meet our quality standards 100% of the time and allow us to plan our business effectively".

"Another benefit is that In-Sight can be operated simply and reliably".
