Barcode Positioning System

By Balluff

 

The new BPS 8 barcode positioning system from Leuze electronic is designed for ease of use and operation. In conjunction with the
MA 8-01 connection unit, the system permits low-cost solutions within the industrial sector.

Optical measuring methods are particularly suitable for establishing the positions of rail-mounted industrial trucks, overhead carrier systems, hoists, rack handling and similar automatic transport systems. They function without mechanical wear or slippage. With the Barcode Positioning System (BPS) from Leuze electronic, positions can be exactly determined in both horizontal and vertical travel. The BPS determines its position relative to the barcode tape by means of a visible red light laser. The codes which are read within the scanning range of the laser beam make it possible to calculate the position with millimetric accuracy using a combination of code information and code position. A large scanning distance is able to compensate for mechanical tolerances. In addition to the BPS 34/37 already mentioned, Leuze has developed a new variant which has been optimised from the functional point of view. The new '
BPS 8 transfers the position values which have been calculated to the higher-level control system via an RS232 interface. For use in industrial environments, such as car body overhead conveyors within vehicle manufacturing or the automotive supply industry, an interfacing unit
(MA 8-01) can adapt the level for the supply voltage as well as for the switching input and output. In addition, this means that a RS485 interface is available. Accommodated in small, robust metal housings, the new
BPS 8 units fulfil Protection Class IP67. The equipment is simple to assemble and allows precise positioning up to a distance of 10,000 metres.
