Abstract

A filling system includes a first component having a fiber opener configured to open fibers. A second component is connected to the first component. The second component includes a fiber blower configured to blow opened fibers. A third component is connected to the second component. The third component includes a weighing system configured to weigh the opened fibers. A fourth component is connected to the third component. The fourth component includes a filler configured to dispose the opened fibers into a shell. Methods of use are disclosed.

Claims

1. A filling system comprising:

a first component comprising a fiber opener configured to open fibers;

a second component connected to the first component, the second component comprising a fiber blower configured to blow opened fibers;

a third component connected to the second component, the third component comprising a weighing system configured to weigh the opened fibers;

a fourth component connected to the third component, the fourth component comprising a filler configured to dispose the opened fibers into a shell; and

a silo positioned between the first component and the second component, the silo comprising a photo eye configured to sense when the silo is full and an air supply configured to blow the opened fibers away from the photo eye when the silo is not full.

2. A filling system as recited in claim 1, wherein the first component comprises a conveyor belt configured to move a bale of fibers to the fiber opener.

3. A filling system as recited in claim 1, wherein the fiber blower comprises a first fiber blower and a second fiber blower that is spaced apart from the first fiber blower by the silo.

4. A filling system as recited in claim 3, further comprising a tube having a first end that is connected to the second fiber blower and a second end that is connected to the silo, the first end comprising perforations configured to pull ambient air into the tube.

5. A filling system as recited in claim 3, further comprising a tube having a first end that is connected to the second fiber blower and a second end that is connected to the silo, the first end comprising an airflow adjustment sleeve configured to control the amount of ambient air that is pulled into the tube.

6. A filling system as recited in claim 3, further comprising a tube having a first end that is connected to the second fiber blower and a second end that is connected to the silo, the first end comprising perforations and an airflow adjustment sleeve configured to change the amount of the perforations that are exposed to ambient air to control the amount of ambient air that is pulled into the tube.

7. A filling system as recited in claim 3, further comprising:

a duct positioned between the second fiber blower and the silo; and

an airline positioned within the duct to blow air into the duct to move the opened fibers through the duct to the second fiber blower.

8. A filling system as recited in claim 1, wherein the fiber blower comprises a first fiber blower and a second fiber blower that is spaced apart from the first fiber blower by a mixer that is configured to mix the opened fibers.

9. A filling system as recited in claim 8, wherein the mixer comprises a perforated transfer gate.

10. A filling system as recited in claim 8, further comprising a duct having a first end that is connected to the first fiber blower and a second end that is connected to a perforated panel of the mixer.

11. A filling system as recited in claim 8, wherein the first fiber blower by a first duct and the second fiber blower is connected to the mixer by a second duct, the ducts each comprising a flexible end that is connected to the mixer to allow the flexible ends to move relative to the mixer.

12. A filling system as recited in claim 8, wherein the mixer includes a chamber and flaps positioned within the chamber, the flaps being configured to rotate within the chamber to move the opened fibers within the chamber.

13. A filling system as recited in claim 8, wherein the mixer includes a ground wire configured to discharge any electrostatic charge within the mixer.

14. A filling system as recited in claim 1, further comprising a mixer, wherein the fiber blower comprises a first fiber blower, a second fiber blower and a third fiber blower, the second fiber blower being spaced apart from the first fiber blower by the mixer, the third fiber blower being spaced apart from the second fiber blower by the silo.

15. A filling system as recited in claim 1, further comprising a mixer, wherein the silo includes a first silo and a second silo, the fiber blower comprising a first fiber blower, a second fiber blower, a third fiber blower and a fourth fiber blower, the second fiber blower being spaced apart from the first fiber blower by the first silo, the third fiber blower being spaced apart from the second fiber blower by a mixer, the fourth fiber blower being spaced apart from the third fiber blower by the second silo.

16. A filling system as recited in claim 1, further comprising a blower positioned between the third component and the fourth component.

17. A filling system as recited in claim 1, wherein the filler comprises a vacuum filling cabinet and a plurality of nozzles that are connected to the cabinet.

18. A filling system as recited in claim 1, wherein the filler comprises a first vacuum filling cabinet, a second vacuum filling cabinet, a plurality of nozzles that are connected to the first vacuum filling cabinet and a plurality of nozzles that are connected to the second vacuum filling cabinet.

19. A filling system comprising:

a first component comprising a fiber opener configured to open fibers;

a mixer configured to mix the opened fibers;

a second component connected to the first component, the second component comprising a fiber blower configured to blow opened fibers, the fiber blower comprising a first fiber blower and a second fiber blower that is spaced apart from the first fiber blower by the mixer, the first fiber blower being connected to the mixer by a first duct and the second fiber blower being connected to the mixer by a second duct, the ducts each comprising a flexible end that is connected to the mixer to allow the flexible ends to move relative to the mixer;

a third component connected to the second component, the third component comprising a weighing system configured to weigh the opened fibers; and

a fourth component connected to the third component, the fourth component comprising a filler configured to dispose the opened fibers into a shell.

20. A filling system comprising:

a first component comprising a fiber opener configured to open fibers;

a mixer configured to mix the opened fibers;

a silo;

a second component connected to the first component, the second component comprising a fiber blower configured to blow opened fibers, the fiber blower comprising a first fiber blower, a second fiber blower and a third fiber blower, the second fiber blower being spaced apart from the first fiber blower by the mixer, the third fiber blower being spaced apart from the second fiber blower by the silo;

a third component connected to the second component, the third component comprising a weighing system configured to weigh the opened fibers; and

a fourth component connected to the third component, the fourth component comprising a filler configured to dispose the opened fibers into a shell.
