Patent number: 8256607Abstract: A monitoring system is provided for a moving conveyor belt having a plurality of embedded reinforcing cords and identification tags. A tag reader detects and identifies the identification tags passing by the tag reader while a belt monitor scans the cords to detect a plurality of magnetic reference points and a damage event of at least one cord. A control unit in communication with the belt monitor and the tag reader analyzes the belt monitor to identify the plurality of magnetic reference points and the damage event. The control unit also acquires a belt location on the moving conveyor belt from a belt map based on the detected and identified identification tag and a magnetic reference point from the plurality of magnetic reference points. When a damage event is identified, a location of the damage event is determined by the control unit based on the acquired belt location.Type: GrantFiled: October 12, 2010Date of Patent: September 4, 2012Assignees: Veyanee Technologies Inc., Advanced Imaging Technologies Ltd.Inventors: Jack Bruce Wallace, Michael John Alport, Jacques Frederick Basson

Patent number: 8069975Abstract: The present invention provides a conveyor belt rip detection system with belts having rip detection inserts that can be more easily integrated into conveyor belts at low cost. These rip detection inserts do not adversely affect the durability of the conveyor belt and can be easily replaced in the event of belt damage. This rip detection system also provides a highly reliable early image of belt damage that can facilitate quick repair before extensive belt damage occurs.Type: GrantFiled: November 17, 2009Date of Patent: December 6, 2011Assignee: Veyance Technologies, Inc.Inventor: Jack Bruce Wallace

Patent number: 7942258Abstract: A digital processor for use in a conveyor belt rip detector, which provides excitation signals at a selected frequency to inverted and noninverted sensor loops on a conveyor belt and then detects corresponding received signals from the sensor loops. The digital processor then performs FFTs on the corresponding received signals to provide respective received signal frequency spectrums. Next magnitude and phase values of the selected frequency in the respective received signal frequency spectrums are used to determine a qualitative state of the sensor loops. The selected frequency has a lowest detected ambient noise level, and the magnitude value is a normalized magnitude value.Type: GrantFiled: May 27, 2010Date of Patent: May 17, 2011Assignee: Veyance Technologies, Inc.Inventors: Jack Bruce Wallace, John James Gartland, Richard Herman Blausey, Edward Louis Kerekes, Jr.

Patent number: 7894934Abstract: A remote conveyor belt monitoring system for monitoring an operation of a conveyor belt at a first geographic location. A local HMI is operable to acquire and store data representing conveyor belt conditions and operating characteristics. First and second computers at different geographic locations acquire the data via an internet. Thus, data relating to the operating conditions of the conveyor belt can be remotely consolidated and monitored by computers at different global locations.Type: GrantFiled: December 5, 2006Date of Patent: February 22, 2011Assignee: Veyance Technologies, Inc.Inventors: Jack Bruce Wallace, Mauricio Pinto Spaolonzi

Patent number: 7740128Abstract: A self-synchronizing system and method for conveyor belt sensor operation is disclosed based on the address of an RFID tag in the belt and the location of that tag in the system memory. A moving conveyor belt system has a plurality of sensors spaced along the belt and a sensor reader for detecting and identifying the presence of a sensor passing by the sensor reader. The belt further includes a plurality of identification tags spaced along the belt and a tag reader for detecting and identifying the presence of a tag passing by the tag reader. Associated time and distance target values are acquired from a calibration table for a next sensor (S1) based upon a detected and identified functional tag. Time and distance counters are initiated. The conveyor belt may be stopped in the event that the next sensor (S1) is not detected before the time and distance target values are exceeded.Type: GrantFiled: November 8, 2005Date of Patent: June 22, 2010Assignee: Veyance Technologies, Inc.Inventors: Jack Bruce Wallace, John James Gartland

Publication number: 20080257692Abstract: A conveyor belt includes at least one rip detection sensor having at least two cords, each cord formed in an endless loop and arranged in a signal inverting configuration, and at least one cross connector connecting the at least two cords so as to arrange the at least two cords in a parallel configuration. The sensor provides a redundancy feature such that should one cord break, the remaining cord allows the sensor to continue operation. The parallel configuration of the cords reduces overall resistance of the sensor and extends the sensor life as the conveyor belt wears.Type: ApplicationFiled: June 5, 2008Publication date: October 23, 2008Applicant: VEYANCE TECHNOLOGIES, INC.Inventor: Jack Bruce Wallace
