Abstract

An apparatus and method for separating recyclable corrugated paper from a stream of commingled waste. Commingled waste is loaded onto a conveyor with two alternating sets of jogger beams. A motor drives the jogger beams out of phase with respect to one another causing the waste to fall between the jogger beams, while corrugated paper remains above and moves along the jogger beams, thereby separating the two components. Optionally, a second stage of jogger beams can be positioned forward of the conveyor to create a drop therebetween to further separate the commingled waste. The jogger beams are cantilevered beyond the motor so that waste falls clear of the motor.

Claims

1. A method to separate corrugated paper from a stream of commingled waste containing corrugated paper and other waste, said method comprising the steps of:

loading the stream of commingled waste onto a conveyor, said conveyor having at least two substantially parallel jogger beams separated by a spacing;

alternating the motion of said two jogger beams to move said stream of commingled waste along said conveyor;

separating the corrugated paper from the other waste as the stream of commingled waste is moved along said conveyor, the other waste falling between and beneath said two jogger beams and said corrugated paper remaining above and moving along said two jogger beams;

collecting said corrugated paper separately from the other waste at a distal end of said conveyor.

2. The method of claim 1 wherein the step of alternating the motion of said two jogger beams further includes the step of moving at least one jogger beam forward and upward while moving at least one jogger beam rearward and downward.

3. The method of claim 1 wherein the step of alternating the motion of said two jogger beams uses a drive motor to move said jogger beams and said jogger beams are cantilevered beyond said drive motor.

4. The method of claim 1 wherein said jogger beams are inclined.

5. A recycling apparatus for separating corrugated paper from a stream of commingled waste containing corrugated paper and other waste, said recycling apparatus comprising:

a conveyor having at least two substantially parallel jogger beams spaced apart from one another, said stream of commingled waste loaded onto said two jogger beams;

a drive mechanism driving each of said jogger beams, said drive mechanism including;

(a) a motor driving said two jogger beams out of phase with respect to one another to move said stream of commingled waste along said conveyor;

(b) a crankshaft driven by said motor;

(c) a link arm extending from a first end of said jogger beam and pivotably connected to said crankshaft;

(d) a first bell crank pivotably mounted beneath said first end of said jogger beam;

(e) a first tie rod connecting said first end of said jogger beam to said first bell crank;

(f) a second bell crank pivotably mounted beneath said jogger beam;

(g) a second tie rod connecting said first bell crank to said second bell crank; and

(h) a slide shoe pivotally connected to said second bell crank and slidingly engaging said jogger beam; and

a collection area beneath the conveyor, the other waste falling between said two jogger beams and into said collection area, the corrugated paper remaining above and moving along said two jogger beams, thereby separating the corrugated paper from the other waste.

6. The recycling apparatus of claim 5 wherein said jogger beams are inclined.

7. The recycling apparatus of claim 5 further comprising a second stage of jogger beams following said conveyor.

8. The recycling apparatus of claim 7 wherein said second stage of jogger beams are positioned lower than the distal end of said conveyor creating a drop therebetween to further separate said stream of commingled waste.

9. The apparatus of claim 8 wherein at least one jogger beam is thrust forward and upward while at least one jogger beam is moved rearward and downward thereby causing the corrugated paper dropping from said conveyor onto said second stage of jogger beams to tumble to further separate the waste from the corrugated paper.

10. The apparatus of claim 5 further comprising a skirt at least partially covering said first and second bell cranks and said slide shoe.

11. The apparatus of claim 5 wherein said jogger beams further include teeth.

12. The apparatus of claim 11 wherein said teeth are formed on a single sheet of metal fashioned into a substantially U-shape and secured to said jogger beams.

13. An apparatus for separating recyclable corrugated paper from a stream of commingled waste containing corrugated paper and other waste, said apparatus comprising:

a conveyor having at least two sets of jogger beams, said stream of commingled waste loaded thereon, and

a drive mechanism including;

(a) a motor, said jogger beams being cantilevered beyond said motor,

(b) a crankshaft driven by said motor,

(c) a link arm extending from a first end of said jogger beam and pivotably connected to said crankshaft, so that said sets of jogger beams are driven out of phase with respect to one another by said crankshaft;

(d) a first bell crank pivotably mounted beneath said first end of said jogger beams;

(e) a first tie rod connecting said first end of each set of jogger beams to said first bell crank;

(f) a second bell crank pivotably mounted beneath said jogger beams;

(g) a second tie rod connecting said first bell crank to said second bell crank for each set of jogger beams; and

(h) a slide shoe pivotally connected to said second bell crank and slidingly engaging at least one jogger beam of each set of jogger beams; and

a collection area beneath said conveyor, with the other waste falling between said jogger beams and into said collection area, said corrugated paper remaining above and moving along and toward a distal end of said jogger beams, thereby separating the corrugated paper from the other waste.

14. The apparatus of claim 13 further including a skirt covering said drive mechanism.

15. The apparatus of claim 13 wherein said jogger beams further include teeth.

16. The apparatus of claim 15 wherein said teeth are formed on a single sheet of metal fashioned into a substantially U-shape secured to said jogger beams.

17. The apparatus of claim 13 wherein said jogger beams are inclined.

18. The apparatus of claim 13 further comprising a second stage of jogger beams positioned forward of said conveyor and lower than the distal end of said conveyor creating a drop therebetween to further separate said stream of commingled waste.
