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 enclosable 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. An apparatus for loading metal scrap material into an ISO standard-compliant shipping container having an internal width [of 7′ 7¾″], an internal height and an external length and defining a volume, the apparatus comprising:
a hopper for receiving the metal scrap material, the hopper comprising a bottom having an external width slightly less than the internal width of the ISO standard-compliant shipping container and opposing side walls having an internal height slightly less than the internal height of said ISO standard-compliant shipping container, and the bottom having a length at least as long as the external length of said ISO standard-compliant shipping container, said hopper comprising a first end and a second end positioned opposite said first end, wherein said hopper has an open top extending between said first and second end and said hopper is fixed in position and oriented so as to enable the ISO standard-compliant shipping container to be moved into engagement with said hopper to thereby receive said hopper therein to extend along the entire length of the ISO standard-compliant shipping container;
a plate disposed within said hopper having a width just less than an internal width of said hopper, and configured to move between said first end and said second end of said hopper; and
a driver configured for moving said plate between said first end and said second end to shift said heavy metal scrap material out of said hopper.
2. The apparatus of claim 1 , wherein said driver comprises a hydraulic cylinder.
3. The apparatus of claim 1 , further comprising a stand mounted near said first end of said hopper configured to support said hopper above the ground at a height approximately equivalent to the height of said ISO standard-compliant shipping container above the ground.
4. The apparatus of claim 1 , wherein said plate is positionable between said first end and said second end of said hopper to define a portion of said hopper to receive the heavy metal scrap material.
5. The apparatus of claim 4 , wherein the portion defines a volume, and the volume of said portion is determined based upon the volume of said ISO standard-compliant shipping container to be filled with said metal scrap material.
6. The apparatus of claim 4 , wherein said plate pushes the metal scrap material contained in said portion into said ISO standard-compliant shipping container.
7. The apparatus of claim 4 , wherein the position of said plate is determined based upon the volume of said ISO standard-compliant shipping container to be filled with the metal scrap material.
8. The apparatus of claim 4 , wherein said hopper is capable of occupying less than the entire volume of said ISO standard-compliant shipping container.
9. The apparatus of claim 1 wherein the driver comprises a chain drive connected to the plate.
10. The apparatus of claim 1 wherein the driver comprises a belt drive connected to the plate.
11. The apparatus of claim 1 wherein the driver comprises a rack and pinion setup, wherein the pinion is connected to a motor and to the plate to move the plate.
12. The apparatus of claim 1 wherein the driver comprises a screw system to move the plate.
13. The apparatus of claim 1 wherein the driver comprises a cable and winch system, wherein the cable routed is to the plate via pulleys.
