Methods and apparatus for freight container loading
Disclosed are apparatuses and methods for use thereof for loading bulk material into freight containers. One apparatus comprises a hopper configured to receive bulk material that is sized and shaped to be at least partially en do sable by a container to occupy a substantial volume of the container and a ram. The ram comprises a plate and a driver configured to move the plate from a back end of the hopper to an open end of the hopper to expel material into a container. Another apparatus comprises a hopper configured to receive bulk, material that is sized and shaped to be at least partially enclosable by a container to occupy a substantial volume of the container and a reciprocating conveyor floor system. Optionally, the apparatuses further include a stand and/or collapsible legs to further support the hopper.
1. A method of loading a shipping container with material comprising:
(a) loading the material into a hopper with a first end and a second end;
(b) first partially enclosing at least a portion of said hopper within said container, wherein said portion occupies substantially the entire volume of said container; and
(c) then transferring said material from said hopper into said container by shifting said material towards an open end of said hopper and by moving said container away from said hopper.
2. The method of claim 1 , wherein the hopper further comprises a movable plate positioned adjacent said material and wherein step (c) comprises causing the plate to move towards said open end.
3. The method of claim 1 , wherein said container is attached to a tractor-trailer.
4. The method of claim 3 , wherein step (c) comprises driving said tractor-trailer forward.
5. The method of claim 1 , wherein step (b) comprises: positioning said container in front of said hopper and moving said container backwards towards said hopper to cause said container to enclose said portion of said hopper.
6. The method of claim 1 , wherein the volume of said portion is determined based upon the volume of said container to be filled with said material.
7. The method of claim 1 , wherein the length of said portion is substantially equal to or less than the length of said container.
8. The method of claim 1 , wherein said hopper is capable of extending into substantially the entire length of said container.
9. A method of loading a shipping container with material comprising:
loading the material into a hopper with a first end and a second end;
enclosing at least a portion of said hopper within said container; and
transferring said material from said hopper to occupy a substantial volume of said container by synchronously shifting said material in said hopper through an open end of said hopper and moving said container away from said hopper.
10. The method of claim 9 wherein said portion occupies substantially the entire volume of said container.
11. The method of claim 10 , wherein the volume of said portion is determined based upon the volume of said container to be filled with said material.
12. A method of loading a shipping container with material comprising:
loading the material into a hopper with a first end and a second end;
enclosing at least a portion of said hopper within said container; and
transferring said material from said hopper to occupy a substantial volume of said container by a combination of shifting said material in said hopper through an open end of said hopper and moving said container away from said hopper;
wherein said portion occupies substantially the entire volume of said container.
13. The method of claim 12 , wherein the volume of said portion is determined based upon the volume of said container to be filled with said material.
