Blockprofile measurement system

Transcription

1 Purpose of the plant Experience shows that it is difficult during the current foaming the exact amount of the block to measure and assess the block form. While the block height can be determined by point measurements at different points in the foam system, the block shape by eye on the cut on the saw is assessed attributive. To get from the estimate to an automatic identified and comparable size, a measurement system was developed, the size of "cross-block" practice is just available. Function of the system The measurement of block height is done with a laser distance meter of the company Sick. With a mobile gantry axis, the laser distance measuring device is transversely procedures to foam device. From the distance of the entire surface, we shall calculate the altitude profile of the foam block. Through integration of the measured height values on the infrastructure, the current cross-sectional area of the block is calculated. The measured values are represented as a curve on a computer screen and showing the cross section and profile of the foam block. The maximum value of the series of measurements indicates the maximum height of the block. Through an iterative calculation method, the maximum rectangle under the curve is determined and displayed. The ratio of the area of this rectangle and the determined block area is the area ratio (FVZ1) as a measure of the achievements the ideal rectangular shape. A second rectangle is created, after the adjustable, admitted to the trimming of the block needed. From the block surface and the newly formed rectangle calculated the surface area ratio (FVZ 2) as a measure of the block of yield after the trimming. Page 1 of ProZa A.Zahler
