The V 4000 camera for folding improves the performance of conventional security systems
A safe Imaging for folding sensor
The new folder V4000 camera offers maximum safety at work and maximum optimisation of the functioning of the folding. This device is the first electro-sensitive safety equipment based on image processing system and has been approved for category 4 in accordance with the European standard EN 954-1 and SIL3 according the EN61508. Moreover, the new V 4000 camera for folding sets new standards with regard to the improvement of processes, variability during different types of folding, installation and availability.
Conventional systems to ensure the dangerous movement, which is the closure of the folder, consist of simple opto-electronic receivers and transmitters, they create the "trancha" and move with it. These systems may find dangerous exploits in the field of protection, but they have serious disadvantages from the point of view of the productivity of the machine. The "visionary" solution of the new folding V4000 camera offers several advantages.
A field of protection adapted to the process is active at the moment in which the tool bending (punch) and the material to be folded appear in the two-dimensional camera image. The height of this area of security decreases in accordance with the position of the awl, which this V4000 for folding mounted, while approaching the matrix. This offers a number of advantages: the thickness of the metal parts to fold, the forms of the pieces to fold and pieces with sidewalls can be bent with the assurances active in different modes of operation: guitar mode for easy folding in a single dimensionMode "Box" for bending multi-dimensional objects such as boxes and how "Top back" to take into account the top rear envelope which supports the piece to be dubbed. The security team can dynamically change the optimum safe mode via selection of the mode of operation. The machine can activate the protection mode most appropriate to the paste to make, one after the other and as many times as necessary, for the same piece. For example first "Standard", then "box" to fold the piece with a side already folded, and finally "came back" for small bent.
Thus it is possible to a greater availability of the folder because of the adjustment in the way of working with production faults.
