Some large libraries use the latest material-handling systems from Swisslog-Telelift and sensors from Leuze Electronic to get fast access times, shorter queues and more economical processes.

An example is the German National Library, Leipzig, which makes nearly 25 million pieces of media available to its users, along with the Jacob-und-Wilhelm-Grimm-Zentrum of the Humboldt University of Berlin (The Grimm Library) and the Berlin State Library.

Each of these large libraries use material-handling systems from Swisslog-Telelift, which make a key contribution in these institutions by accelerating order processing and relieving personnel of manual transport tasks.

Swisslog-Telelift manufactures conveyor systems for the in-house handling of lightweight goods and documents.

In the library sector, the company handles the entire logistics process with all of Swisslog-Telelift’s transport systems being integrated according to individual requirements in the now-standard self-service lending systems used in libraries, even in the customer terminals where media are checked out and returned.

At Berlin’s University Library and the German National Library in Leipzig, systems were implemented during the course of renovation work, with Swisslog’s Multlift system being used in both of these applications.

The Multilift technology consists of conveyor belt sections and roller conveyors for the horizontal transport within a building floor and fully automatic container lifts for the vertical transport between individual building floors.

The Multilift system operates with direct destination control.

The destination is set on code carriers located directly on the container, either with slider coding bars or rotary coding discs.

The contactless destination queries performed by the Leuze BCL 34 barcode readers detect the destination setting at all decision points along the transport system.

In the Grimm Library in Berlin, rotary coding discs from Leuze are used.

The codes can be quickly and easily set by hand with a turning motion.

On the other hand, the slider coding bars used at the state library and at the German National Library save space by offering unlimited nesting capability for the containers.

The barcode readers are equipped with an integrated Profibus interface, eliminating the need for Profibus gateways and RS-232 components, which considerably reduces the system costs.

The Leuze BCL 34 barcode readers read the codes that have been manually preset on the slider coding bars and transfer the data via Profibus directly to the control, positively identifying each container’s destination.

Leuze’s barcode scanners with Profibus integration allow the scanner to be programmed directly with the software tool of the Profibus master.

This makes it possible to exchange a barcode reader in just seconds without any special technical knowledge.

The BCL 34 state can be queried and monitored directly by the Profibus diagnostics tool.

A continuous container lift that functions similar to a paternoster is used in the Berlin State Library, and in the Grimm Library, a linear lift is used to connect the eleven floors to one another.

The Multilift systems are loaded and unloaded fully automatically.

For the vertical movement of the containers in the lift, the control uses the signals provided by Leuze’s AMS 200 laser distance measurement devices, transmitting via Profibus, using integrated interfaces.

The sensors achieve an absolute accuracy of +/-2mm over a measurement distance of 120m, with fast position calculation in the device, enabling modern drive technology to be used to its full potential.

Leuze AMS 200 devices provide warning signals that inform the user in good time of decreasing laser diode performance, impermissible temperatures or soiling of the optics.

All in all, the technological alliance between Swisslog-Telelift and Leuze ensures that a visitor to the library quickly obtains his or her book at the check-out/return terminal and can return it there with ease after reading.

Books can be returned and made available for use again in just minutes, even over long distances in multiple buildings and over several floor levels.
