Abstract

Claims (47)

1 . A sensor assembly for a conveyor belt, comprising:

a load cell attachable to a link of a modular conveyor belt and configured to measure tension in the belt; and

a housing having:

a first cavity configured to receive at least a portion of the load cell;

a second cavity configured to receive one or more electronic components; and

two or more electronic components disposed within the second cavity of the housing;

wherein the two or more electronic components includes a power source; and

wherein the power source includes at least one capacitor configured to periodically discharge power for operation of the another of the two or more electronic components.

2 . The sensor assembly of claim 1 , wherein the load cell has a first end and a second end; and

wherein the first end includes an opening through which a fastener may be inserted in order to attach the first end of the load cell to a body of the link.

3 . The sensor assembly of claim 2 , wherein the second end of the load cell has a second opening configured to receive a connecting rod of the belt.

4 . The sensor assembly of claim 1 , wherein the one or more electronic components are configured for inductive charging of the power source.

5 . The sensor assembly of claim 1 , wherein the one or more electronic components includes a memory device configured to store data received by the sensor assembly.

6 . The sensor assembly of claim 5 , wherein the memory device is configured to store data selected from at least one of the following:

location data;

gyroscopic sensor data; and

acceleration sensor data.

7 . A tension sensing system for a conveyor belt, comprising:

a first link pivotally connectable to other links of the conveyor belt;

a sensor assembly attached to the first link, the sensor assembly including:

a load cell attachable to the first link and configured to measure tension in the belt; and

a housing having:

a first cavity housing at least a portion of the load cell; and

a second cavity housing one or more electronic components;

wherein the one or more electronic components includes a memory device configured to store data received by the sensor assembly; and

wherein the memory device is configured to store data selected from at least one of the following:

data regarding the location of the sensor assembly;

belt angle data from a gyroscopic sensor; and

belt acceleration data.

8 . The system of claim 7 , wherein the load cell has a first end and a second end; and

wherein the first end includes an opening through which a fastener may be inserted in order to attach the first end of the load cell to a body of the first link.

9 . The system of claim 7 , wherein the one or more electronic components includes a power source; and

wherein the power source includes at least one capacitor.

10 . The system of claim 9 , wherein the one or more electronic components are configured for inductive charging of the power source.

11 . A conveyor belt, comprising:

a plurality of links connected by a plurality of connecting rods, the plurality of links including at least a first link;

a sensor assembly attached to the first link, the sensor assembly including:

a load cell attachable to the first link and configured to measure tension in the belt; and

a housing having:

a first cavity configured to receive at least a portion of the load cell;

wherein the first link is substantially U-shaped, including a first leg, a second leg, and a connecting portion extending between the first leg and the second leg; and

wherein the second leg of the first link includes a lateral extension having a recess configured to receive a portion of the load cell.

12 . The conveyor belt of claim 11 , wherein the housing of the sensor assembly includes a second cavity configured to receive one or more electronic components.

13 . The conveyor belt of claim 11 , wherein the lateral extension includes a receptacle for a fastener configured to affix the load cell to the lateral extension of the link.

14 . The conveyor belt of claim 11 , wherein a first end of the load cell is attached to the lateral extension with a fastener and a second end of the load cell includes an opening through which one of the connecting rods extends such that the load cell is configured to detect elongation of the second leg of the link due to tension in the conveyor belt.

15 . The conveyor belt of claim 11 , wherein the housing further includes a second cavity; and

wherein the sensor assembly further includes one or more electronic components disposed within the second cavity of the housing.
