Patent number: 8662290Abstract: A conveyor belt monitoring system is disclosed that uses sensors to measure magnetic disruptions (“events”) in a conveyor belt which are indicative of one or more splice joints, rip panels and reinforcing cord damage. The system may comprise a plurality of sensing components, including coils or Hall Effect sensors for sensing rip panels, splices and generalized reinforcing cord damage. The system may also have RFID-based rip panels and may use RFID chips to identify various belt components. A PLC-based control system may communicate with the aforementioned components via an Ethernet link. Data received by the control system is used to chart belt wear and damage trends and to provide user alarms when signal levels exceed predetermined norms. The system may stop the belt when imminent belt failure is predicted. The PLC-based control system is highly scalable and will integrate easily into existing conveyor control systems and facility-wide monitoring systems.Type: GrantFiled: September 16, 2009Date of Patent: March 4, 2014Assignee: Fenner Dunlop Americas, Inc.Inventors: Mick Twigger, George Mark Myers, David Hurd

Patent number: 8657105Abstract: A system and method are disclosed for controlling a conveyor belt condition monitoring system, and for automatically providing user alarms and system trips when sensed conditions exceed acceptable values. The system may use sensors to measure magnetic disruptions (“events”) in belt components and an algorithm may be used to monitor changes in these disruptions over time. The magnitude of these changes can then be used to predict when belt failures will occur. The system may also be used to sense when imminent failure of the belt will occur and to automatically stop the belt before failure occurs. An integrated display provides detailed information on the measured belt events and enables the user to customize alarm/trip levels and to assess problem as conditions via a virtual private network or the Internet while the belt is operating. The system is modular so that its features may be selectively integrated into existing facility-wide monitoring systems.Type: GrantFiled: September 16, 2009Date of Patent: February 25, 2014Assignee: Fenner Dunlop Americas, Inc.Inventors: Mick Twigger, George Mark Myers

Publication number: 20120217132Abstract: A conveyor belt rip monitoring system is disclosed. The system includes at least one rip panel having a conductive loop positioned in or on a conveyor belt so that the loop extends substantially across the width of the belt. The conductive loops may be formed from metallic or non-metallic materials. An RFDD chip is electrically coupled to the loop and provides a signal to an RFID interrogation unit positioned on the conveyor structure indicative of the health of the conductive loop. If a break is sensed in the loop, the RFID chip sends an appropriate signal to the interrogation unit which passes the information to a processing system. A unique resistor or diode may be included in the circuit between the chip(s) and the legs of the loop so that the interrogation unit can distinguish one leg or loop from another. If the break in the loop is determined to be due to a rip in the conveyor belt, the processing system alerts a user of the rip condition via an attached display device.Type: ApplicationFiled: September 16, 2009Publication date: August 30, 2012Applicant: FENNER DUNLOP AMERICAS, INC.Inventors: Mick Twigger, George Mark Myers

Patent number: 7815043Abstract: In improved reinforced conveyor belt structure is disclosed having a segmented reinforcing structure for enabling enhanced in-plane expansion of the belt under conditions of extreme in-plane experienced during operation. The belt comprises at least one elastomer layer and at least one reinforcing layer. The reinforcing layer may comprise a continuous strip disposed along the longitudinal center line of the conveyor belt. A series of laterally-extending reinforcing strips are disposed on either side of the center strip, radiating outward toward respective edges of the belt. These laterally-extending strips are spaced apart from one another to form a series of flexibility enhancing gaps therebetween, thus enabling the belt to elongate at its edges without undue restraint from the reinforcing layer. The laterally-extending strips may be oriented perpendicular to the center strip, or they may be oriented at oblique angles with respect to the center strip. The reinforcing layer may comprise one or more plies.Type: GrantFiled: August 10, 2007Date of Patent: October 19, 2010Assignee: Fenner Dunlop Americas, Inc.Inventors: John Hawkins, Geoff Normanton, Arthur B.

Patent number: 7759266Abstract: A conveyor belt reinforcing fabric weave is disclosed, having a plurality of center tension warps crimped about a plurality of middle wefts. Upper and lower wefts lie above and below the middle wefts. The upper and lower wefts are in opposition to each other and in non-opposition with the center wefts. Binder warps are interlaced above and below the central tension warps in alternating sequence, with at least one of the binder warps interlacing upper and lower wefts other than those interlaced by an adjacent binder warp. Interlacing of the middle wefts by the central tension warps locks the wefts in place, providing enhanced resistance to faster pullout. The lack of straight tension warps provides a highly flexible fabric that can be used in multi-ply applications. A conveyor belt incorporating one or more plies of the inventive fabric is disclosed, as is a method for manufacturing the belt.Type: GrantFiled: July 13, 2007Date of Patent: July 20, 2010Assignee: Fenner Dunlop Americas, Inc.Inventors: John Hawkins, Geoff Normanton
