Claims
- 1. In an on-line system for reclaiming a portion of oriented and unoriented film produced on an extrusion line, wherein at least one carrier stream transfers said portion of said film to a means for both entangling said oriented and unoriented film to form a collection thereof containing at least 25% by weight of unoriented film and chopping said collection to form a chopped reclaim therefrom, and wherein at least one other carrier stream transfers said chopped reclaim to a means for transferring both virgin resin and said chopped reclaim to a means for plasticizing such materials which is a part of said line, an improvement to said means for transferring both virgin resin and said chopped reclaim comprising: a first container which is suitable for storage of a virgin resin and is adapted to transfer a first and second part of said virgin resin, a second container which is adapted both to separate incoming chopped reclaim from said at least one other carrier stream and to induce mixing of any virgin resin simultaneously entering therein, a first means for transferring which is adapted to transfer a first part of said virgin resin from said first container to said second container in such a manner that said virgin resin and said chopped reclaim which simultaneously enters therein become intermixed so as to form a mixture therein, wherein a second means for transferring is adapted to transfer said mixture from said second container to said means for plasticizing, and wherein a third means is adapted to transfer said second part of said virgin resin from said first container to said means for plasticizing at a location downstream from where said mixture enters said means for plasticizing.
- 2. The improvement of claim 1, wherein said means for plasticizing comprises an extruder with a screw; said means both for: entangling and chopping comprises a cyclone attached to a chopper means; said second container comprises a cyclone; said first means comprises a conduit with a powered auger therein; said second means comprises at least one conduit with at least one powered auger therein; and said third means comprises a conduit which is adapted to gravitationally transfer said second part of said virgin resin from said first container to said means for plasticizing.
- 3. The improvement of claim 2, wherein said second means comprises at least a first and a second conduit with at least a first and a second powered auger respectively contained therein, said first conduit with said first powered auger therein being adapted to transfer said mixture from said second container to the inside of said second conduit, and said second conduit with second powered auger therein being adapted to transfer independently said mixture to said extruder.
- 4. The improvement of claim 3, wherein at least part of the rotary power both to said powered auger of said first means and said first powered auger within said first conduit of said second means is transferred by a drive means from said screw of said extruder.
- 5. The improvement of claim 4, wherein said drive means comprises a first, second, third and fourth cog wheel, a first chain and a second chain; said first cog wheel being attached to said screw of said extruder so as to rotate in response to any rotary movement of said screw, said first chain being adapted to couple said first cog wheel and said second cog wheel so as to cause rotation of said second cog wheel in response to any rotary movement of said first cog wheel, said second cog wheel being attached to said first powered auger, which comprises a part of said second means for transferring, so as to cause rotation thereof in response to any rotary movement of said second cog wheel, said third cog wheel being attached to said first powered auger so as to rotate in response to any rotary movement of said first powered auger, said second chain being adapted to couple said third cog wheel and said fourth cog wheel so as to cause rotary motion of said fourth cog wheel in response to any rotary movement of said third cog wheel, and said fourth cog wheel being attached to said powered auger, which comprises a part of said first means for transferring so as to cause rotation thereof.
- 6. The improvement of claim 5, wherein said first cog wheel is torque limiting.
- 7. The improvement of claim 5, wherein at least a portion of said second powered auger which comprises a part of said second means for transferring is located within said conduit which comprises a part of said third means for transferring.
- 8. In an on-line system for reclaiming a portion of oriented and unoriented film produced on an extrusion line, wherein at least one carrier stream transfers said portion of said film to a means for both entangling said oriented and unoriented film to form a collection thereof containing at least 25% by weight of unoriented film and chopping said collection to form a chopped reclaim therefrom and wherein at least one other carrier stream transfers said chopped reclaim to a means for transferring both virgin resin and said chopped reclaim to a means for plasticizing such materials which is a part of said line, an improvement to said means for transferring both virgin resin and said chopped reclaim comprising: a first container, a cyclone, a first conduit with a first auger therein, a second conduit with a second auger therein, a third conduit with a third auger therein, a passageway, a meter, and a drive means; wherein said first container is adapted (i) to receive and to store virgin resin and (ii) to transfer a first portion of said virgin resin to the interior of said first conduit and to transfer a second portion of said virgin resin gravitationally to the interior of said passageway wherein said cyclone is adapted (i) to receive and to separate chopped reclaim from said at least one other carrier stream, (ii) to receive said first portion of said virgin resin from said first conduit so that such virgin resin and said chopped reclaim simultaneously being received in said cyclone become intermixed under the influence of said at least one other carrier stream so as to form a mixture thereof which collects within said cyclone, and (iii) to transfer said mixture to the interior of said second conduit, wherein said passageway is attached at one end to said first container and at the other end to the interior of said means for plasticizing, said passageway being adapted to accommodate said third conduit with said third auger while also transferring gravitationally said second portion of said virgin resin into said means for plasticizing; wherein said first conduit is connected at one end to said first container and at the other end to said cyclone, said one end of said first conduit being adapted to receive said first portion of said virgin resin and upon rotation of said first auger to transfer said first portion of said virgin resin to said cyclone; wherein said second conduit is connected at one end to said cyclone and at the other end to said third conduit, said one end of said second conduit being adapted to receive said mixture from within said cyclone and said other end of said second conduit being attached to said third conduit so that upon rotation of said second auger said mixture is transferred to the interior of said third conduit; wherein said third conduit is supported within said first container, one end of said third conduit being disposed within said passageway so that upon rotation of said third conduit said mixture is transferred to the interior of said means for plasticizing; wherein said third auger within said third conduit has attached at one end thereof said motor, wherein said motor is adapted to impart said rotary motion to said third auger; wherein said drive means comprises a first, second, third, and fourth cog wheel, a first chain and a second chain, said first cog wheel being attached to a screw of said extruder so as to cause rotation of said first cog wheel in response to any rotary movement of said screw, said first chain being adapted to couple said first cog wheel and said second cog wheel so as to cause rotation of said second cog wheel in response to any rotary movement of said first cog wheel, said second cog wheel being attached to said second auger so as to cause rotation thereof in response to any rotary movement of said second cog wheel, said third cog wheel being attached to one of said second cog and said second auger so as to rotate in response to any rotary movement of said second auger, said second chain being adapted to couple said third cog wheel and said fourth cog wheel so as to cause rotation of said fourth cog wheel in response to any rotary movement of said third cog wheel, said fourth cog wheel being attached to said first auger so as to cause rotation of said first auger in response to any rotary movement of said fourth cog wheel.
