psb innovations in the
overhead conveyor technology

The most recent example for psb’s expertise in the handling of hanging items is the development of a coupled trolley mtl, based on the advanced psb micro trolley systems technology mtr.

With a loading length of 100 mm, the new mtl system can carry a total load of up to 5 kg. Thus, this system is especially suitable for the handling of hanging items, which are transported in sets: the transport of several garments/textiles, or of a complete car-set of seat covers conveyed on a single load carrier mtl.

Despite the length of the individual trolleys, the overall conveying and sorting capacity is very high: the system achieves a performance of over 5,000 mtl per hour in Power & Free operation, no matter whether the goods have to be transported, buffered, sorted or sequenced.

Like the sister product mtr, the mtl trolleys can be buffered in gravity lanes up to 35 m long. This buffering capacity allows for a highly efficient system configuration, because in these lanes, there is no need for drives nor related components.

The transfer from the gravity buffer to the automated track is initiated by opening the gravity lanes. The collision-tolerant carriers of the main track directly take over the mtl and transport them further on the system. An expensive carrier control during the transfer process into the main track is not necessary.

The system family comprises of fully-automated loading and unloading stations. Utilizing multi-step sorting algorithms, any possible required order of items can be established.

Matrix barcodes are used as standard coding of the mtl. Coding with RFID is also possible.

The system installation is controlled by the approved psb selektron WMS Warehouse Management System: in interaction with the psb selektron MFC Material Flow System, the system installation is optimally organized. A psb selektron SCADA module is utilized for visualizing the entire system.

The mtl has outstanding features, with respect to throughput, mobility, expandability and scalability. Moreover, through the non-driven buffer tracks and the non-monitored transfer into the main tracks, highly efficient integrated systems can be realized.
