IVS is the integrated system that allows the artificial vision of the leather, with the consequent recognition of the quality and defect zones and the automatic nesting of the pieces.
In the first level of IVS ™ automation a projector is mounted directly on the loading area or cutting area of the digital cutter, the operator will stretch the leather under the projection and nest the pieces directly on the material, seeing them projected. In this way he will have total control of the actual nesting before the cut.
Also in this second level of automation the projector is mounted directly on the loading are or cutting area of the digital cutter, the operator will stretch the leather under the projection delimiting the outline through a rapid process of digitization, the automatic nesting software on leather will provide the positioning of the pieces optimizing the leather to the maximum. The speed of this solution accelerates production rates and improves nesting performances.
At the highest level of automation, dedicated to sectors that require considerable production speed, such as the automotive and the furniture industries, the projector and cameras for the artificial vision of the leather are also mounted on an inclined off-line table. The leather on the off-line table, will perform the detection of the outline and the software will automatically nest the pieces, with the possibility of nesting some parts manually. A bar code will then be applied to the leathers to allow the digital cutter to recognize the individual leather. The projection will then be mounted on the off-line table, in order to see the nested pieces on the material and have complete control of the nesting. The operator of the cutting machine will then load the nesting file recalling the leather with the barcode on the ZUND cutter, that will perform the cut. The storage of the leathers previously viewed off-line, codified with the barcode in the DB allows to have the cutting machine always operational and a 24/7 workflow.
