Abstract
1349546 Endless conveyers BANDO KAGAKU CO Ltd 7 Sept 1971 [7 Sept 1970 27 Feb 1971 24 May 1971 3 July 1971] 41740/71 Heading B8A [Also in Division G1] Longitudinal cracks in a conveyer belt are detected by embedding at intervals along and across the width of the belt rubber magnets 5 which are short circuited by iron plates 6. If a longitudinal crack appears in the belt near one of the magnets 5 this will be ruptured and the associated iron plate 6 displaced therefrom so that the magnetic flux from the magnet is no longer short circuited and reaches a detector positioned under the belt. The detectors may be inductance coils, magnets, diodes, relays or magneto resistors connected in a circuit, Fig. 5 (not shown), which controls the belt motor to stop the belt when a crack is detected. A plurality of detectors may be distributed over the whole width of the belt or a single extended detector used. In order to prevent the iron plates 6 being ruptured together with the rubber magnets, particularly when a wide belt is used, each single magnet 5 is replaced by a plurality of magnet elements having corresponding iron plates and are disposed in a zig-zag arrangement on the belt, Fig. 8 (not shown). Leakage magnetic flux effects are obviated by using a single detector and consecutively arranging a plurality of magnet/plate pairs transverse to the belt but at different longitudinal displacements so that they lie along a line inclined to the belt in a stepwise arrangement, Fig. 9 (not shown). In order to ensure that the belt is not stopped by the detection of leakage fluxes the detector Fig. 11 may include two main detectors 4bL; 4bR and two auxiliary detectors 4aL, 4aR which are connected in a circuit Figs. 12 or 13 (not shown) whereby in the absence of a crack both main detectors emit identical signals and when a crack is present one signal is greater than the other, and only when a signal is simultaneously generated by both auxiliary and main detectors will the control circuit be energized. Reference has been directed by the Comptroller to Specification 1,151,335.
