Optical length and speed measurement

In highly automated production processes measurement of operational throughput delivers essential data to control process parameters or, as in the manufacturing of piece goods, an automatic start and end recognition mechanism allows autonomous length measurement. When working with hot, elastic, highly sensitive, or dough-like materials, it is impossible to use tactile sensors such as odometers or tacho rolls. The accuracy of a mechanical sensor system is also reduced by slippage, which in practice can lead to measuring errors of 10% or more. In both cases, non-contact optical metrology provides significant benefits. Well Gain Cable Systems Ltd has added two products to its range – a multi-wire drawing machines and Electrolytic tinning plant – which have been added with the help of Kunshan Hongtai Machinery and Electric Equipment Ltd. The multi-wire drawing machine, with continuous annealer, is an ideal solution for customers who are looking for efficiency, cost effectiveness and reliability in drawing and bunching wire strands. With a maximum inlet wire diameter of 2mm, the machine is able to draw bare Cu, tinned Cu and silver plated Cu wires down to an outlet diameter of

or better. The measured length is transmitted to subsequent electronics using an industry standard incremental interface. An alternative synchronous serial interface (SSI) is also available. In addition, an electrical output signal compatible with common incremental encoders is available and can be directly connected to control systems, electrical counters or frequency inverters.

With the Speel 3000, Zumbach offers a gauge that can be used for applications that demand a high degree of accuracy at high velocities. Speel 3000 is available for a measuring distance of 300mm and is said to achieve an accuracy of 0.05%

Two new products from Well Gain

0.15-0.40mm at max. line speed 32m/s. Both 8-wire and 16-wire machines are available. The electrolytic tinning plant, complete with water treatment system, is a waste water free process of producing the best quality tin plated copper wires of wire diameter 1.0-2.6mm at max line speed 13m/s. The tinned wires are suitable for further wire drawing and continuous annealing.
