Lingl Innovation in Record Time at Vandersanden
With the new directive in the labour catalogue of the Dutch construction site inspectorate, from 2010 pavement blocks have to be machine-laid on all surfaces wherever this is possible, and the laying of pavers has to be actually carried out in this way.
This means for the companies involved that the layers of bricks or pavers have to be supplied on pallets with the desired laying pattern ready for machine-laying. With the erection of the installation for the laying of pavers the Dutch/Belgian Vandersanden Group (Spijk, Netherlands) has reacted to this demand. Being the major family-managed brick manufacturer in Europe, Vandersanden is specialised in the production of facing and pavement clinkers. In total the company is producing approximately 100 million pavement blocks as well as approximately 500 million facing bricks per year and supplies these products from its factories in The Netherlands and Belgium to countries all over the world.
The pavers laying installation developed by Hans Lingl GmbH (Krumbach, Germany) is described as a real innovation: the first installation of this kind was set into operation in a customer's factory, in its type and scope based on a completely new design. So it is more than remarkable, says the company, that the realisation of the project was completed within 4 months. This is cited as evidence of the innovative capacity and the implementing capability of Lingl.
The pavers laying installation consists of individual lines and can be developed and enlarged according to required performance. The capacity of the individual line is 3,600 pcs/h (ref size Dutch Waal format 200mm x 100mm x 50mm). The laying varieties are almost unlimited. It is possible to lay any bond, to programme a large number of different patterns and to blend colours. The system of Vandersanden at Spijk comprises five lines and reaches a capacity of 18,000 pcs/h (approx. 500 pallets per shift). For comparison, the conventional production procedure requires 45 persons for supplying 18,000 pcs/h pavement blocks ready to be laid. Nowadays only two persons are needed for operating and supervising the Lingl installation.
The complete product handling is carried out by vacuum grippers having been especially designed for this purpose. These grippers take the blocks from the pallet-free transport packs by layers, separate them and compose layers according to a defined pattern. These layers which are ready for laying are directly set onto pallets and wrapped. By means of a laying device, also covered by the Lingl delivery programme, the block layers are taken off and laid without any problems.
The laying installation developed by Lingl is eminently suited for any type and size of pavement blocks. The highly flexible vacuum technique offers a maximum degree of flexibility in the handling of the products. The absolute reliability is secured even under most difficult conditions like heat, dust and sand which, due to modern compressor and filter equipment, cannot affect the system. The new type of user interface is combined with the well-proven Lingl machine operating and visualisation technique and allows the easy creation of the most various individual laying patterns. The correction values for dimensional differences can be directly entered at the operating panel.
