GEBHARDT Automated Guided Vehicle

Automated guided vehicles (AGV) are the innovative solution for the future in times of digitalization and Industry 4.0 in order to ensure a permanent, flexible product and a more reliable flow of goods in intralogistics. They improve automation and solve the problems of continually increasing complexity. They make it possible to meet the demands of increasingly variable products in small batch numbers, continually changing production conditions as well as just-in-time provision of goods, permitting short throughput times while also optimizing utilization of individual stations for high overall availability. The AGV can be used to optimize the internal material flow as well as the entire value-added chain. Depending on AGV type, goods of different weights can be autonomously moved through the warehouse. Therefore, automated guided transport systems are the innovative response to the internal material flow of the future.

The automated guided vehicles by GEBHARDT Fördertechnik permit future-proof innovative goods transport in intralogistics. They perform logistics tasks autonomously and cooperatively. The AGV used for this apply dynamic route planning, which implements a loose link between process modules. The autonomous, smart and self-organized vehicles for intralogistics and assembly are navigated by inductive or visual tracking depending on demand, supported additionally by RFID sensors that are installed in the floor next to the navigation tracking front of forks, stations, etc., in order to position the AGV with a deviation not exceeding ten millimeters. Additionally, it is possible to use visual 2D-barcodes to achieve a positioning accuracy of five millimeters deviation at most. The inductive version is made possible by measurement of the magnetic field via line conductors, while visual navigation uses a camera-based sensor system. That recognizes the painted or glued-on navigation lines without being susceptible to interference from reflection, sunlight and hall lighting. The AGVs recognize obstacles on their own with their integrated safety scanner, which enables them to slow down and stop. If the route remains occupied by another vehicle, the AGV is able to switch to energy saving mode and report that the route is already occupied. Once the route has been cleared, the AGV will move on automatically. In order to ensure error-free navigation, we recommend using several technologies together. Differential control permits going around bends as well as turning in place. The autonomous transport systems transfer energy either on the inductive navigation route, on an inductive charging station or by contact. The advantage of conductive charging is the maintenance- and wear-free system that permits routes without any obstacles. An additional power accumulator is integrated as well to ensure 24/7 operation. This accumulator can be with Supercaps or a lead-crystal accumulator. The Supercaps are quick to charge, have a long service life and are also maintenance-free. The lead-crystal accumulators have a high energy density and can be used for a long time before they need to be recharged. They are also very robust and long-lived, which is also reflected in the large number of charge cycles.

The superordinate material flow computer operated by the customer is connected to the vehicle administration, route administration, energy management, etc., via a logistics controller and communicates with the individual automated guided vehicles via Wi-Fi with UDP protocol (User Datagram Protocol).

The automated guided vehicles are operated via a touch-sensitive screen that makes it possible to request the status or errors of the AGV directly on site via a user interface. It is also possible to guide the vehicle manually using an interface.

The automated guided vehicles are available in three different versions in order to transport loads from 500 kg to 3000 kg at speeds of up to 1.5 m/s. The autonomous transport systems are available in different designs by combination of standardized assemblies.
