Abstract

A conveyor assembly is configured to convey and maintain compression of multiple compressible batts. Adjacent pairs of conveyor systems within the conveyor assembly define a space between the pair of conveyor systems for receiving and conveying compressible batts. Each pair of adjacent conveyor systems has at least two upper belts in a coplanar relationship. One of the two upper belts travels in an advancing direction and other upper belt travels in a returning direction. Each pair of adjacent conveyor systems also has at least two lower belts in a coplanar relationship. One of the lower belts travels in the advancing direction and the other lower belt travels in the returning direction.

Claims

1. A conveyor assembly configured to convey and maintain compression of multiple compressible batts, the assembly comprising a vertical stack of at least two conveyor systems, wherein

adjacent pairs of conveyor systems within the conveyor assembly define a space between the pair of conveyor systems for receiving and conveying compressible batts;

and

,

ii) and at least two lower belts in a coplanar relationship and positioned below and facing the space between the pair of conveyor systems, with one of the two lower belts positioned below the space mounted for traveling in the advancing direction relative to the conveyor assembly and the other of the two lower belts positioned below the space mounted for traveling in the returning direction.

2. The assembly of claim 1 including shields associated with each of the belts traveling the returning direction, the shields being positioned to prevent contact between the belts and a compressible batt contained between the conveyor systems.

3. The assembly of claim 1, wherein the upper advancing belt and the lower returning belt are in a vertically aligned relationship, and wherein the lower advancing belt and the upper returning belt are in a vertically aligned relationship.

4. The conveyor assembly of claim 1, wherein each belt operatively engages and extends between a forward driving roller assembly configured to drive one belt in the advancing direction and a rearward driving roller assembly configured to drive an adjacent belt in the returning direction.

5. The conveyor assembly of claim 4, wherein the forward driving roller assembly includes an axis having mounted thereon:

i);

a drive roller configured to drive the advancing belt, and ii) an idler roller configured to allow the returning belt to freely rotate about the forward drive roller axis; and

wherein the rearward driving roller assembly includes an axis having mounted thereon;

i) a rearward drive roller configured to drive the returning belt, and ii) an idler roller configured to allow the advancing belt to freely rotate about the rearward driving roller axis.

6. The conveyor assembly of claim 1, including a controlling device configured to allow each conveyor system to be separately controlled.

7. The conveyor assembly of claim 4, including a controlling device configured to allow each forward driving assembly and each rearward driving assembly to be separately controlled.

8. The assembly of claim 1 wherein a pair of adjacent conveyor systems has:

i) four upper belts in a coplanar relationship and positioned above and facing the space between the pair of conveyor systems, with two of the four upper belts positioned above the space mounted for traveling in the advancing direction and the other of the four upper belts positioned above the space mounted for traveling in the returning direction; and

,

ii) four lower belts in a coplanar relationship and positioned below and facing the space between the pair of conveyor systems, with two of the four lower belts positioned below the space mounted for traveling in the advancing direction and the other of the four lower belts positioned below the space mounted for traveling in the returning direction.

9. The assembly of claim 8 including shields associated with each of the belts traveling the returning direction, the shields being positioned to prevent contact between the belts and a compressible batt contained between the conveyor systems.

10. The assembly of claim 8, wherein the upper advancing belts and the lower returning belts are in a vertically aligned relationship, and wherein the lower advancing belts and the upper returning belts are in a vertically aligned relationship.

11. The conveyor assembly of claim 8, wherein each belt operatively engages and extends between a forward driving roller assembly configured to drive the advancing belt in the advancing direction and a rearward driving roller assembly configured to drive the returning belt in the returning direction.

12. The conveyor assembly of claim 11, wherein the forward driving roller assembly includes an axis having mounted thereon:

i) forward drive rollers configured to drive the advancing belts, and ii) idler rollers configured to allow the returning belts to freely rotate about the forward drive roller axis; and

wherein the rearward driving roller assembly includes an axis having mounted thereon;

i) rearward drive rollers configured to drive the returning belts, and ii) idler rollers configured to allow the advancing belts to be freely rotate about the rearward driving roller axis.

13. The conveyor assembly of claim 8, wherein the four upper belts are in a coplanar relationship and a first and third belt are the advancing belts and the second and fourth belts are the returning belts;

and wherein the four lower belts are in a coplanar relationship and a first and third belt are the returning belts and the second and fourth belts are the advancing belts.

14. The conveyor assembly of claim 8, wherein the four upper belts are in a coplanar relationship and a first and fourth belt are the advancing belts and the second and third belts are the returning belts;

and wherein the four lower belts are in a coplanar relationship and a first and fourth belt are the returning belts and the second and third belts are the advancing belts.

15. The conveyor assembly of claim 8, including a controlling device configured to allow each conveyor system to be separately controlled.

16. The conveyor assembly of claim 8, including a controlling device configured to allow each forward driving assembly and each rearward driving assembly to be separately controlled.

17. A method for conveying compressible batts and for maintaining compression of multiple compressible batts, comprising:

conveying multiple compressible batts using a conveyor assembly configured to convey and maintain compression of multiple compressible batts, the assembly comprising a vertical stack of at least two conveyor systems, wherein adjacent pairs of conveyor systems within the conveyor assembly define a space between the pair of conveyor systems for receiving and conveying compressible batts; and

,

a pair of adjacent conveyor systems has;

i) at least two belts in a coplanar relationship and positioned above and facing the space between the pair of conveyor systems, with one of the two belts positioned above the space mounted for traveling in an advancing direction relative to the conveyor assembly and the other of the two belts positioned above the space mounted for traveling in a returning direction, and

ii) and at least two belts in a coplanar relationship and positioned below and facing the space between the pair of conveyor systems, with one of the two belts positioned below the space mounted for traveling in the advancing direction relative to the conveyor assembly and the other of the two belts positioned below the space mounted for traveling in the returning direction.
