Abstract

Systems and methods of providing powder are disclosed. A system includes a powder hopper, one or more sensors, a feeder hopper and a processor in operable communication with the one or more sensors and the feeder hopper. The powder hopper is configured to provide a powder to a pair of rollers. Each of the one or more sensors is configured to determine a characteristic of the powder in the powder hopper. The feeder hopper is configured to provide the powder to the powder hopper. The processor is configured to cause the feeder hopper to provide the powder to the powder hopper in response to the characteristic of the powder in the powder hopper being less than a threshold.

First claim

What is claimed is:

1 . A system comprising:
a first powder hopper configured to provide a first powder to a first pair of rollers; one or more first sensors, wherein each first sensor is configured to determine a characteristic of the first powder in the first powder hopper; a first feeder hopper configured to provide the first powder to the first powder hopper; and a processor in operable communication with the one or more first sensors and the first feeder hopper, wherein the processor is configured to cause the first feeder hopper to provide the first powder to the first powder hopper in response to the characteristic of the first powder in the first powder hopper being less than a first threshold.

2 . The system of claim 1 , wherein the first powder hopper is positioned adjacent to the first pair of rollers.

3 . The system of claim 1 , wherein:
the one or more first sensors comprise a level sensor; and the characteristic of the first powder comprises a height of the first powder within the first powder hopper.

4 . The system of claim 1 , wherein:
the one or more first sensors comprise a weight sensor; and the characteristic of the first powder comprises a weight of the first powder within the first powder hopper.

5 . The system of claim 1 , further comprising:
a second powder hopper configured to provide a second powder to a second pair of rollers; one or more second sensors, wherein each second sensor is configured to determine a characteristic of the second powder in the second powder hopper; and a second feeder hopper configured to provide the second powder to the second powder hopper, wherein the processor is in operable communication with the one or more second sensors and the second feeder hopper, wherein the processor is further configured to cause the second feeder hopper to provide the second powder to the second powder hopper in response to the characteristic of the second powder in the second powder hopper being less than a second threshold.

6 . The system of claim 5 , wherein the second powder hopper is positioned adjacent to the second pair of rollers.

7 . The system of claim 5 , wherein:
the one or more second sensors comprise a level sensor; and the characteristic of the second powder comprises a height of the second powder within the second powder hopper.

8 . The system of claim 5 , wherein:
the one or more second sensors comprise a weight sensor; and the characteristic of the second powder comprises a weight of the second powder within the second powder hopper.

9 . The system of claim 5 , wherein the first powder is the same as the second powder.

10 . The system of claim 5 , wherein the first powder is different from the second powder.

11 . The system of claim 5 , wherein the first feeder hopper is connected to the second feeder hopper.

12 . A method comprising:
providing first powder from a first powder hopper to a first pair of rollers; determining, by at least one first sensor, a characteristic of the first powder within the first powder hopper; and delivering first powder from a first feeder hopper to the first powder hopper in response to the characteristic of the first powder being less than a first threshold.

13 . The method of claim 12 , wherein the first powder hopper is positioned adjacent to the first pair of rollers.

14 . The method of claim 12 , wherein:
the at least one first sensor comprises a level sensor; and the characteristic of the first powder comprises a height of the first powder within the first powder hopper.

15 . The method of claim 12 , wherein:
the at least one first sensor comprises a weight sensor; and the characteristic of the first powder comprises a weight of the first powder within the first powder hopper.

16 . The method of claim 12 , further comprising:
providing second powder from a second powder hopper to a second pair of rollers; determining, by at least one second sensor, a characteristic of the second powder within the second powder hopper; and delivering second powder from a second feeder hopper to the second powder hopper in response to the characteristic of the second powder being less than a second threshold.

17 . The method of claim 16 , wherein the second powder hopper is positioned adjacent to the second pair of rollers.

18 . The method of claim 16 , wherein:
the at least one second sensor comprises a level sensor; and the characteristic of the second powder comprises a height of the second powder within the second powder hopper.

19 . The method of claim 16 , wherein:
the at least one second sensor comprises a weight sensor; and the characteristic of the second powder comprises a weight of the second powder within the second powder hopper.
