HERZOG expertise in pneumatic systems

The pneumatic tube installation enables the transport of carriers containing samples of various types to different tube stations within the pneumatic system. The technology is based on quick transportation using air as power source. A compressor generates the required pressure and suction for transport of the pneumatic carrier. Alternatively, the pneumatic system can make use of compressed air that is abundant in production plant.

Pneumatic systems

The pneumatic tube installation enables the transport of carriers containing samples of various types to different tube stations within the pneumatic system. The technology is based on quick transportation using air as power source. A compressor generates the required pressure and suction for transport of the pneumatic carrier. Alternatively, the pneumatic system can make use of compressed air that is abundant in production plant. The product of differential pressure acting on the carrier and the cross-sectional area of the carrier has to be equal to the weight force of the carrier during upward movement and the friction forces. The pneumatic carriers have a waisted design that allows passing of turns and bends. The distance between the two protruding seal rings is usually 3 to 5 times the tube diameters. In general, this guarantees that carriers can transit bends with radii that are 5 to 10 times of the tube diameter.

Depending on whether a blower or compressed air is used, the speed of the pneumatic carrier can between 6 m/s and 20 m/s. In case of specially configured pneumatic systems and air tubes, an even higher velocity is possible. Usually, the external diameter of pneumatic tubes is 80 mm whereas the internal diameter is 75 mm. At special request, systems with larger diameters are available as well.
Usually, there is a direct connection between plant and laboratory stations. Alternatively, diverters can be integrated to allow transportation of carriers from a sending station to different receiving stations.
According to the sample type, different pneumatic carriers are available. For cold powder material and other light samples, we use carriers made from plastic. For hot powder and steel or iron samples, carriers are made from aluminum. For transportation of metallic samples, tailor-made inserts are used. This allows the reliable sample handling in fully automatic systems while increasing lifetime of carriers.
Pneumatic systems are available as manual or automatic versions. Using a manual system, the operator inserts the carrier manually into the plant station and removes it manually from the receiving station. Usually, the subsequent sample processing is manual as well.
In case of automatic operation, different options are available. For powder material, the plant station covers automatic dosing, filling into carrier and transportation into the laboratory.

Within the laboratory station, unpacking of the carrier and filling of the sample into a cup takes place. Then a transport system or robot forwards the cup for further sample preparation. After emptying and cleaning, the carrier is locked and sent back to the plant station. Metallic samples are unpacked and possibly cooled down within the laboratory station. The unpacking station can handle different sample shapes. Usually, unpacking is followed by fully automatic sample preparation and analysis.
The control of the pneumatic system is due to the coordinated interaction between the PLC of the pneumatic station, the Scada system (PrepMaster) and the level 2 system of the client. The intelligent control of the system enables the efficient and quick sample transport into the laboratory.
