Abstract

A temperature monitor is provided for use on a conveyor belt. The temperature monitor includes a first wall and a second wall. The first wall and the second wall are generally parallel to one another. The temperature monitor also includes a first anchor and a second anchor. The first wall is attached to the first anchor at a first end and the first wall is attached to the second anchor at a second end. The second wall is attached to the first anchor at a first end and the second wall is attached to the second anchor at a second end. The temperature monitor further includes a temperature deformation mechanism defined between the first wall and the second wall. The temperature deformation mechanism is altered in an instance in which a predetermined temperature is reached. A method of manufacturing a temperature monitor and a temperature monitor system are also provided.

First claim

What is claimed is:

1. A temperature monitor for use on a conveyor belt, the temperature monitor comprising:

a first anchor and a second anchor, wherein the first wall is attached to the first anchor at a first end of the first wall and the first wall is attached to the second anchor at a second end of the first wall, wherein the second wall is attached to the first anchor at a first end of the second wall and the second wall is attached to the second anchor at a second end of the second wall; and
a temperature deformation mechanism defined between the first wall and the second wall, wherein the temperature deformation mechanism comprises a temperature deflection strip configured to deflect towards the first wall or the second wall in an instance in which a predetermined temperature of the conveyor belt is reached.

2. The temperature monitor of claim 1 , wherein the temperature monitor is configured to be placed on an exterior of the conveyor belt or within a top cover of the conveyor belt.

3. The temperature monitor of claim 1 , wherein the first wall, the second wall, the first anchor, and the second anchor are a unitary housing.

4. The temperature monitor of claim 1 , wherein the temperature deflection strip is attached to the first wall at a first end of the temperature deflection strip and the temperature deflection strip is attached to the second wall at a second end of the temperature deflection strip.

5. The temperature monitor of claim 1 , wherein the first wall of the temperature monitor is configured to be located perpendicular to the movement of the conveyor belt during operation.

6. The temperature monitor of claim 1 , wherein the temperature deformation mechanism further comprises a plunger mechanism and a temperature deformation material, wherein the temperature deformation material is configured to restrict the movement of the plunger mechanism until a predetermined temperature of the conveyor belt is reached.

7. The temperature monitor of claim 6 , the plunger mechanism comprises a plunger attached at spring end of the plunger to a spring, wherein the spring is attached to the plunger at a plunger end of the spring and attached to the second anchor at a wall end of the spring.

8. The temperature monitor of claim 7 , wherein in an instance the predetermined temperature has not been reached, the temperature deformation material is configured to fill an area between the plunger and the first anchor.

9. The temperature monitor of claim 7 , wherein the temperature deformation material is configured to be a solid at below the predetermined temperature and a non-solid at or above the predetermined temperature, wherein in an instance in which the predetermined temperature is reached, the temperature monitor is permanently deformed.

10. A temperature monitor for use on a conveyor belt, the temperature monitor comprising:
a first wall and a second wall, wherein the first wall and the second wall are generally parallel to one another;
a first anchor and a second anchor, wherein the first wall is attached to the first anchor at a first end of the first wall and the first wall is attached to the second anchor at a second end of the first wall, wherein the second wall is attached to the first anchor at a first end of the second wall and the second wall is attached to the second anchor at a second end of the second wall; and
a temperature deformation mechanism defined between the first wall and the second wall, wherein the temperature deformation mechanism comprises a plunger mechanism and a temperature deformation material, wherein the temperature deformation material is configured to restrict the movement of the plunger mechanism until a predetermined temperature of the conveyor belt is reached.

11. The temperature monitor of claim 10 , the plunger mechanism comprises a plunger attached at spring end of the plunger to a spring, wherein the spring is attached to the plunger at a plunger end of the spring and attached to the second anchor at a wall end of the spring.

12. The temperature monitor of claim 11 , wherein in an instance the predetermined temperature has not been reached, the temperature deformation material is configured to fill an area between the plunger and the first anchor.

13. The temperature monitor of claim 11 , wherein the temperature deformation material is configured to be a solid at below the predetermined temperature and a non-solid at or above the predetermined temperature, wherein in an instance in which the predetermined temperature is reached, the temperature monitor is permanently deformed.

14. A temperature monitor for use on a conveyor belt, the temperature monitor comprising:
a first wall and a second wall, wherein the first wall and the second wall are generally parallel to one another;
a first anchor and a second anchor, wherein the first wall is attached to the first anchor at a first end of the first wall and the first wall is attached to the second anchor at a second end of the first wall, wherein the second wall is attached to the first anchor at a first end of the second wall and the second wall is attached to the second anchor at a second end of the second wall; and
a temperature deformation mechanism defined between the first wall and the second wall, wherein the temperature deformation mechanism is altered in an instance in which a predetermined temperature is reached,
wherein the temperature monitor is configured to be placed on an exterior of the conveyor belt or within a top cover of the conveyor belt.

15. The temperature monitor of claim 14 , wherein the temperature deformation mechanism comprises a temperature deflection strip configured to deflect towards the first wall or the second wall in an instance in which a predetermined temperature of the conveyor belt is reached.

16. The temperature monitor of claim 15 , wherein the temperature deflection strip is attached to the first wall at a first end of the temperature deflection strip and the temperature deflection strip is attached to the second wall at a second end of the temperature deflection strip.

17.
