Abstract

A wear detection system for detecting beam wear along a support flange of a beam includes a rail riding portion configured to travel along the support flange and a processor portion connected to the rail riding portion. The rail riding portion includes a wear measurement system comprising one or more measuring sensors configured to provide an output indicative of thickness of the support flange. The processor portion includes an integrated processing system that receives the output of the one or more measuring sensors and generates measurement information based on the output.

Claims

1. A wear detection system for detecting beam wear along a support flange of an overhead beam of an overhead conveyor system, the wear detection system comprising:

a rail riding portion configured to hang within a channel of the overhead beam of the overhead conveyor system and travel along the support flange of the overhead beam with the rail riding portion at least partially within the channel; and

a processor portion connected to the rail riding portion;

the rail riding portion comprising a wear measurement system comprising one or more measuring sensor pairs configured to provide an output indicative of thickness of the support flange, wherein the one or more measuring sensor pairs comprise a first measuring sensor and a second measuring sensor in a face-to-face relationship above and below the support flange;

the processor portion comprising an integrated processing system that receives the output of the one or more measuring sensor pairs and generates measurement information based on the output, the measurement information being indicative of wear on the support flange of the overhead beam.

2. The system of claim 1, wherein the rail riding portion comprises a frame and a sensor mount assembly that mounts the one or more measuring sensor pairs to the frame, the processor portion connected to the frame such that the processor portion hangs from the frame at a location below the overhead beam of the overhead conveyor system during a wear detection process.

3. The system of claim 1, wherein the rail riding portion includes one or more wheels arranged and configured to ride along the support flange of the overhead beam of the overhead conveyor system.

4. The system of claim 1, wherein the rail riding portion comprises an encoder having a rotary wheel that engages the support flange and is configured to provide an output indicative of location along the support flange of the overhead beam of the overhead conveyor system to the integrated processing system.

5. The system of claim 4, wherein the rail riding portion comprises a detecting sensor arranged and configured to detect an indicator marker and provide an output to the integrated processing system.

6. The system of claim 5, wherein the integrated processing system includes logic that resets the encoder based on output from the detecting sensor when the indicator marker is detected.

7. The system of claim 1, wherein the first measuring sensor is a first laser displacement sensor configured to be at least partially located within the channel of the overhead beam of the overhead conveyor system and the second measuring sensor is a second laser displacement sensor configured to be located underneath the support flange of the overhead beam of the overhead conveyor system.

8. A method for detecting beam wear along a support flange of an overhead beam of an overhead conveyor system using a wear detection system, the method comprising:

moving a rail riding portion of the wear detection system hanging within a channel of the overhead beam of the overhead conveyor system along the support flange of the overhead beam with the rail riding portion at least partially within the channel, the wear detection system comprising a processor portion connected to the rail riding portion;

generating an output indicative of thickness of the support flange using one or more measuring sensors of a wear measurement system carried by the rail riding portion;

generating measurement information using an integrated processing system of the processor portion using the output of the one or more measuring sensors, the measurement information being indicative of wear on the support flange of the overhead beam; and

providing an output to the integrated processing system indicative of location of the wear detection system along the support flange of the overhead beam of the overhead conveyor system using an encoder having a rotary wheel that engages an underside of the support flange; and

wherein the encoder is biased into engagement with the underside of the support flange by the biasing arm, the integrated processing system generating location information based on the output of the encoder.

9. The method of claim 8 further comprising providing the location information to an external computer.

10. The method of claim 8 further comprising providing an output to the integrated processing system using a detecting sensor upon detecting an indicator marker.

11. The method of claim 10 further comprising the integrated processing system resetting the encoder based on the output from the detecting sensor when the indicator marker is detected.

12. The method of claim 8, wherein the one or more measuring sensors comprise a pair of laser displacement sensors.

13. The method of claim 8 further comprising providing the measurement information to an external computer.

14. The method of claim 13 further comprising reporting the measurement information to a user using the external computer.

15. The method of claim 14, wherein the measurement information is reported to a user using a mobile computing device.

16. A wear analysis system for detecting beam wear along a support flange of an overhead beam of an overhead conveyor system, the wear analysis system comprising:
