Abstract

A substrate verification system is utilized for verifying substrate location and orientation in a catalytic converter mat wrapping mechanism. A mat wrap mechanism reads data from a substrate. A verification mechanism compares the identifier data with stored data. If the substrate is verified as correct, the verification mechanism activates the mat wrap mechanism. If the data from the substrate does not match the data in a system an alert is activated. If there is an error, the wrapping process will not be activated. The present invention therefore provides a substrate verification system for verifying substrate location and orientation.

Claims

1. A substrate verification system for converter substrates comprising:

a wrap mechanism with a wrap surface;

a mat wrap on said wrap surface of said wrap mechanism;

at least one substrate on said wrap mechanism on top of said mat wrap;

a reader mounted adjacent said wrap surface for reading an identifier on said substrate; and

a controller programmed to compare the identifier on said substrate to stored data prior to activation of said wrap mechanism.

2. The verification system in claim 1 wherein the reader is one of a plurality of readers.

3. The verification system in claim 1 wherein said identifier is a barcode and said reader is a barcode scanner.

4. The verification system in claim 1 wherein the wrap mechanism includes a wrap roller to apply said mat wrap to said at least one substrate.

5. The verification system as recited in claim 1, wherein a computer is connected to said controller, said computer for input and storage of said stored data.

6. The system as recited in claim 5, wherein a printer is attached to said verification system to create a converter label using information from said computer.

7. The system as recited in claim 6, wherein said information includes data from said identifier, data stored on said computer, and data generated by said computer.

8. A method of verifying a substrate comprising the steps of:

a) placing a mat wrap on a wrap mechanism;

b) placing a substrate with an identifier on the mat wrap;

c) reading data associated with the identifier on the substrate with a computer verification system; and

d) comparing the data associated with the identifier with stored data prior to activation of the wrap mechanism.

9. The method as recited in claim 8, wherein said step d) further includes comparing an orientation of said substrate against said stored data.

10. The method as recited in claim 8, wherein said step d) further includes comparing a substrate part number against said stored data.

11. The method as recited in claim 8, further including the step of:

e) activating a system alert when the identifier data does not match the stored data.

12. The method as recited in claim 11, further including the step of:

f) inhibiting operation of the wrap mechanism and waiting for an operator to check the alert based upon said step e).

13. The method as recited in claim 12, further including the step of:

g) the operator restarting the wrap mechanism after checking the alert.

14. The method as recited in claim 8, further including the step of:

h) applying the mat wrap to the substrate if the computer verification system confirms the substrate is correct.

15. The method as recited in claim 14, further including the steps of:

i) placing the substrate in a converter housing;

j) printing a converter label; and

k) applying the converter label to the converter housing.

16. A method of verifying a substrate comprising the steps of:

a) placing a mat wrap on a wrap mechanism;

b) placing a substrate on the mat wrap; and

c) reading the substrate with a computer verification system to verify orientation or position of the substrate prior to activation of the wrap mechanism.

17. The method as recited in claim 16, further including the step of:

d) activating a system alert based upon a determination that the substrate is in the incorrect orientation or position.

18. The method as recited in claim 17, further including the step of:

c) inhibiting operation of the wrap mechanism and waiting for an operator to check the alert based upon a determination that the substrate is in the incorrect orientation or position.

19. The method as recited in claim 18, further including the step of:

g) the operator activating the wrap mechanism after checking the alert after said step e).

20. The method as recited in claim 16, further including the step of:

h) applying the mat wrap to the substrate based upon a confirmation by the computer verification system that the substrate is in the correct position and orientation.

21. The method as recited in claim 20, further including the steps of:

i) placing the substrate in a converter housing;

j) printing a converter label; and

k) applying the converter label to the converter housing.
