Title: Paper machine - has dual detectors in the drying range to sense a break in the paper
Inventor: RUF GUENTHER
IPC: B26D5/34
Filed: 1992-05-20
Abstract: Paper entering the drying cylinders of a paper machine is diverted when a break is identified. The detector to identify the break is a sender to receiver type, fitted at two locations of the drying range. The first formulates a pattern in memory, in which the paper is absent, and the second recognises the pattern, and identifies it with the actual situation, to actuate the reject mechanism. Pref., the web of paper (3) is produced at the wet end, at the squeeze rollers (10). It then enters the first set of four drying cylinders (20), which have reversal rollers (22) to redirect the paper between the drying felt and bowl (21). The exposed paper at the second roller lies on top of the felt and the roller. The detector (a) is directed to this point (30) and repeated at the second drying range (20). The detectors are in a tube with lenses for projection and reception, set at an angle of 30 deg. The connections out of the tube is through a conduit with fibre optic cables. Projection is from a halogen lamp and received at an analyser circuit. Air is blown through the conduit to maintain a state of cleanliness to ensure efficiency. The first detector formulates a pattern in memory of the colour of the felt, as distinct from the paper, compared with white light after analysis with red, blue and green filters. This is then compared with the second detector output, and if the two indicate a pattern of felt, then the paper is absent, and separated at the mechanism (40). ADVANTAGE - The detection is efficient, avoiding incorrect interpretation. Damage to equipment is avoided, which may happen when a break is overlooked and allowed to continue.
