Abstract

This invention relates to a system for efficiently transporting large quantities of initially loose pieces of irregularly shaped scrap sheet metal by temporarily compressing batches of such pieces together into unitary slabs and then forming stacks of numerous slabs, arranged in closely fitted rows within open-top railroad cars or truck trailers. Each slab is formed by ramming a batch of pieces against a vertical plate so that the slab is generally vertically arranged. The slab is then allowed to gravity-fall upon a downwardly tilted table. A second slab is formed and similarly allowed to fall on the table in end-to-end contact with the first slab. The table is then tilted into a horizontal position. A horizontal magnet is positioned to overlap and engage both slabs simultaneously. The magnet is supported by a crane which lifts and moves the magnet over the open-top railroad car or truck and deposits the pair of slabs into an adjacent pair of stacks. The successive stacks are arranged in closely positioned rows for substantially filling the car or trailer which then transports the slabs to a recycling location.

Dependent claims

A system for transporting large quantities of initially loose, separated, irregularly shaped, pieces of thin scrap sheet metal comprising:

a compactor having a compactor chamber with a rear end and a forward, discharge end, for receiving a predetermined size batch of numerous loose pieces;
a horizontally reciprocatable ram arranged within the chamber for ramming the pieces against a plate covering said compactor chamber open end;
said ram being reciprocal towards said plate for forming a temporarily compacted, unitary slab arranged vertically against said place;
said plate being removable upwardly for passage of the slab through the opening so that the slab may be discharged from the chamber;
a flat table arranged beneath and at the discharge opening of the chamber, with said table normally sloping downwardly in a forward direction relative to the chamber, whereby the slab emerging from the chamber discharge opening will gravity-fall downwardly upon the table in face-to-face contact therewith and slide down the table a predetermined distance;
a magnet having a substantially flat, horizontally arranged face of a size and shape for substantially overlapping a slab resting upon the table;
a lift member connected to the table for raising the table into a horizontal plane and thereby arranging a slab on the table in a horizontal position;
a crane arranged above the magnet for lifting and moving the magnet laterally, relative to the table, above an open-top container, such as a railroad car or truck trailer arranged adjacent the table;
whereby the crane may lower the magnet with its attached slab for positioning the slab with similarly formed additional slabs in stacks, formed in rows of stacks, within such container for substantially filling the volumetric space within the container and the container may then be moved for transporting the slabs to a recycling facility.

A method as defined for efficiently transporting large quantities of initially separated, loose, irregularly shaped pieces of scrap sheet metal from a location where such scrap pieces are initially located to a recycling facility remote therefrom, comprising repetitive cycles of:

(a) collecting a predetermined size batch of a number of pieces in a compression chamber;
(b) compressing the batch of pieces together against a vertical support plate at an end of the chamber to form a large, vertically arranged, wide, high and relatively thin slab formed of temporarily compressed together pieces;
(c) removing the plate and permitting the slab to fall, under the force of gravity, forwardly of the chamber and down upon the face of a downwardly sloped table so that the slab slides down the table a predetermined distance;
(d) moving the table into a horizontal position so that the slab is arranged in a generally horizontal plane upon the horizontally arranged table;
(e) positioning an electromagnet above the slab with the magnet substantially overlapping and engaging the slab for lifting the slab from the table;
(f) moving the magnet laterally, that is, sidewise of the table into a position above a transportation container;
(g) lowering the magnet with the slab into the container;
(h) arranging the slab within the container for forming a stack of successive slabs;
(i) repeating the cycle and forming successive stacks of slabs, side-by-side and end-to-end within the container for substantially filling the container;
whereby the filled container may be transported to a recycling facility and unloaded for recycling the scrap metal pieces.

7 more elements

A system for efficiently transporting large quantities of initially loose, separated pieces of scrap sheet metal comprising:

a compressor having a horizontally arranged compression chamber having a rear end and a forward, opened discharge end with a collection area adjacent said discharge end;
a horizontally reciprocatable ram for ramming a batch of scrap pieces through the collection area and against a vertically arranged backing plate to form an upright slab of compacted-together pieces;
a conveyor system for continuously feeding scrap pieces from a source, downwardly through a feed opening located above the ram and into the collection area;
a horizontally arranged cover sheet arranged upon the ram upper portion for moving with the ram beneath, thereby temporarily closing, said feed opening as the ram moves through the collection area towards the backing plate;
whereby pieces moving downwardly through the feed opening, when the ram moves forwardly towards the backing plate land upon and are momentarily collected upon the ram cover sheet;
and a scraper member located in the chamber above the ram cover sheet for contacting and pushing pieces collected upon the ram cover sheet off the cover sheet so that the pieces fall into the collection area as the ram retracts toward the rear end of the chamber, to form a batch of pieces in the compression area;
whereby pieces are continuously fed into the compressor and batches of said pieces are intermittently formed in the collection area by the forward and rearward movements of the ram relative to the backing plate.
