The SPF – Safe Press Feed system has been designed to control the mat at the infeed to the continuous press.
The SPF provides a continuous and rapid control of the mat as it goes into the press to promptly warn if the mat is not straight or has curved upwards in which case permanent and expensive damage could be caused to the press.
The system consists of a SFHH (Safe For Human Health) millimetre wave sen-sor with ISM band (61.00 – 61.50GHz) controlled by a PLC system to ensure a real time response. The millimeter wave band is reflected to the sensor by a mirror placed opposite the production line. The position of the sensor is essential for deducing the conditions in which it is to operate and it requires a rapid response, but above all an accurate (real-time) response to collect and process the data. The millimetre wave band will therefore be at a slightly high-er level to that of the mat. The maximum response time of the complete sys-tem is equivalent to 300ms. When mat thickness reaches the pre-set alarm threshold, the PLC enables a hardware signal to signal the hazard and provide a contact which may be used to discharge the high pressure circuit of the press cylinders. The sensor is positioned on a vertical linear support to be installed next to press infeed just a couple of mm higher than the mat. The sensor is positioned automatically at the height set on the relative production page in the software. Movement and sensor have been designed to work safely in an environment where dust and vapours are present. A smooth aluminium mirror is placed on the other side of the line.
