Quality control for data cable production

The Centerview 8000 from Sikora is designed to deliver non-contact continuous measurements of 8-point eccentricity, 4-axis diameter and 8-point ovality during the production of data cables. The online repeatability and accuracy of these non-contact measurements provide optimum control and productivity on today’s production lines at all line speeds. A feature of the Centerview is the automatic positioning of the gauge head to the cable position. With this design, guide rollers are not required to achieve precise single measuring values, even at the micron level. Centerview 8000 records the single measuring values with highest precision. These are displayed at 4-points (diameter) and 8-points (eccentricity, ovality) on the processor system Ecocontrol 600, 1000 or 2000. Instantly, the operator has clear information about eccentricity values that can be used for control or crosshead adjustments. Centerview 8000 is available as a stand-alone gauge head with direct connection to a control system or a data collection system for SPC (statistical process control). It can be combined with the processor system, Ecocontrol, for constant accurate online measurement and control. The cloud diagram provides an additional way to present the measuring values of the ongoing measurement at the Ecocontrol. It provides information on distribution of short-term variation of eccentricity in graphical form. Each dot corresponds

to one single measuring value of the eccentricity in relation to the amount and angle. The extension of the cloud diagram is the indicator for the standard deviation of the eccentricity. The display of the single eccentricity values in the cloud diagram shows the operator what eccentricity values remain and what fluctuation the product has, even after a perfect centring. This visualisation of the single values provides an option for the operator to take appropriate measures to minimise the eccentricity.
