The 3D inspection system is an extension of the SHV200 and SHV500 to the measuring system, which allows the quality control of all products on the production board in terms of both height and surface. The system is mounted on the wet side directly behind the block machine. 3D laser technology enables accurate quality analysis: the surface and height of the concrete blocks are analysed at the same time.

MEASURING METHOD:

R&W measuring systems analyse the height of the production board and the height of the concrete block.

The 3D sensor, in combination with 3-point lasers, can measure the height of all products on the production pallet.

The 3D system also uses the relative height between the top edge of the board and the top edge of the stone to measure the height. This measuring principle makes the 3D Inspection system independent of the changing dimensions and quality of production pallets.

DETECTION OF PRODUCT SURFACE DEFECTS:

The device displays product heights with a resolution of 0.1 mm. The measurement accuracy is +/- 0.5 mm.

In addition to height measurement, the 3D sensor can analyze the surface of stones for defects. This is made possible by a special 3D camera and a bright laser line. This enables the sensor to accurately inspect even dark-coloured concrete products.

Optionally, the system can be equipped with an additional high-resolution 2D camera with illumination to detect small cracks and spots in the texture of the blocks.

BENEFITS:

◎ accurate height measurement of all products on the production plate
◎ detailed inspection of blocks for irregularities such as bulges, cracks, cavities, etc.
◎ possibility of extending existing height measuring systems from R&W (SHV200 / SHV500)
◎ measurement of freshly manufactured concrete products on the production boards in circulation in the height range 20-490 mm
◎ early detection of defects
◎ reduction of waste
◎ data acquisition and analysis
