Sub stream auto sampling
A sub stream auto sampling system includes an inspection unit and a sorter unit. The inspection unit includes a camera configured to capture an image of a sample, a light configured to illuminate a sample, a processor configured to process the captured image, and a memory configured to store the captured image. The sorter unit is configured to divert a sub stream of samples, from a main stream of samples, toward the inspection unit. The output of the inspection unit may be directed to the main stream of samples, or the output of the inspection unit may be directed to a collection unit. In addition to the inspection performed by the inspection unit, weighing of the sub stream of samples may also be performed by a weighing unit before the sub stream of samples are routed to the main stream of samples or the collection unit.
1. A system, comprising:
an inspection unit, comprising:
a camera configured to capture an image of a sample;
a light configured to illuminate a sample;
a processor configured to process the captured image;
a memory configured to store the captured image; and
a sorter unit that is configured to divert a sub stream of samples, from a main stream of samples, toward the inspection unit, wherein the sorter unit comprises:
a vacuum system comprising:
a device that is capable generating a vacuum;
a pressurized air inlet; and
a valve, wherein the pressurized air inlet is connected to the valve, and wherein the valve controls a flow of pressurized air through the device.
2. The system of claim 1 , wherein the inspection unit is an in-flight 3D inspector.
3. The system of claim 1 , wherein at least one sample of the sub stream of samples passes through the inspection unit.
4. The system of claim 1 , wherein the inspection unit further comprises an output chute that directs the sub stream of samples to the main stream of samples.
5. The system of claim 1 , wherein the inspection unit further comprises an output chute that directs the sub stream of samples to a collection unit.
6. The system of claim 1 , further comprising a weighing unit.
7. The system of claim 6 , wherein the weighing unit comprises a strain gauge.
8. The system of claim 6 , wherein the weighing unit comprises a force transducer.
9. The system of claim 6 , wherein the weighing unit comprises an output chute that directs the sub stream of samples from the weighing unit to the main stream of samples.
10. The system of claim 6 , wherein the weighing unit comprises an output chute that directs sub stream of samples from the weighing unit to a collection unit.
11. The system of claim 6 , wherein the sub stream of samples passes through the weighing unit before passing through the inspection unit.
12. The system of claim 6 , wherein the sub stream of samples passes through the inspection unit before passing through the weighing unit.
13. The system of claim 1 , wherein the inspection unit captures a sample image while the sample is traveling along a conveyor belt.
14. The system of claim 1 , wherein the sorter unit comprises a mechanical pedal system.
15. The system of claim 1 , wherein the sorter unit comprises an air jet system.
16. The system of claim 1 , wherein the sorting unit diverts a sample while the sample is traveling along a conveyor belt.
17. The system of claim 13 , wherein the sorter unit is electronically controlled.
18. The system of claim 13 , wherein the sorter unit is pneumatically controlled.
19. A method, comprising:
(a) diverting a sample from a main stream of samples toward an inspection unit;
(b) inspecting the sample by the inspection unit, wherein the inspecting includes illuminating the sample, capturing an image of the sample, and storing the captured image, wherein the inspecting of (b) is performed in part by a camera and in part by a processor; and
(c) after the inspecting of (b), directing the sample back to the main stream of samples, wherein the directing of (c) is performed in part by an output chute.
20. A method, comprising:
(a) diverting a sample from a main stream of samples toward an inspection unit;
(b) inspecting the sample by the inspection unit, wherein the inspecting includes illuminating the sample, capturing an image of the sample, and storing the captured image, and wherein the inspecting of (b) is performed in part by a camera and in part by a processor; and
(c) after the inspecting of (b), directing the sample to a collection unit, wherein the directing of (c) is performed in part by an output chute.
