Abstract

An adjustable over and under line feed system having a first end, a second end, a plurality of adjustable first support legs, a plurality of adjustable second support legs, and a plurality of adjustable support cross members connected substantially perpendicular to a corresponding one of the plurality of adjustable first support legs and a corresponding one of the plurality of adjustable second support legs, and a conveyor assembly positioned substantially perpendicular to the plurality of adjustable support cross members.

Claims

1. An over and under line feed system having a first end and a second end comprising:

a plurality of first support legs;

a plurality of second support legs, the plurality of second support legs spaced apart from the plurality of first support legs;

a plurality of adjustable support cross members positioned between the first and second support legs;

a conveyor assembly comprising a lower conveyor and an upper conveyor; and

an elevator assembly positioned at the first end,

wherein the elevator assembly comprises spaced elevator supports.

2. The line feed system as claimed in claim 1, wherein the plurality of adjustable support cross members lie in substantially the same imaginary plane.

3. The line feed system as claimed in claim 1 wherein the conveyor assembly comprises at least one conveyor track assembly and a plurality of indexing rails.

5. The device as claimed in claim 1 wherein the elevator assembly further comprises a workstation.

6. The device as claimed in claim 1 wherein the elevator assembly further comprises an adjustable elevator.

4. An over and under line feed system having a first end and a second end comprising:

a plurality of first support legs;

a plurality of second support legs, the plurality of second support legs spaced apart from the plurality of first support legs;

a plurality of adjustable support cross members positioned between the first and second support legs;

a conveyor assembly; and

an elevator assembly positioned at the first end,

wherein the elevator assembly comprises two substantially parallel elevator supports connected to each other by a support cross member, wherein at least one of the substantially parallel elevator supports is connected to the first end of the over and under line feed system.

7. An over and under line feed system having a first end and a second end comprising:

a plurality of first support legs;

a plurality of second support legs, the plurality of second support legs spaced apart from the plurality of first support legs;

a plurality of adjustable support cross members positioned between the first and second support legs;

a conveyor assembly; and

an elevator assembly positioned at the first end,

wherein the elevator assembly further comprises a movable elevator,

wherein the movable elevator comprises an adjustable elevator cross member,

a pair of adjustable, spaced-apart, elevator support members, a pair of adjustable, spaced-apart elevator base members, and an adjustable elevator base cross member, wherein the elevator cross member is positioned between the pair of elevator support members, and the adjustable elevator base cross member is positioned between the pair of elevator base members.

8. A method of converting an over and under line feed system to accommodate a larger or smaller container, the over and under line feed system having a first end, a second end, a plurality of adjustable first support legs, a plurality of adjustable second support legs, a plurality of adjustable support cross members, at least one support cross member connected substantially perpendicular to a corresponding one of the plurality of adjustable first support legs, and substantially perpendicular to a corresponding one of the plurality of adjustable second support legs, two movable elevator supports connected to each other by a support cross member, and an adjustable elevator positioned adjacent to the elevator supports comprising the step of adjusting at least one of the plurality of adjustable support cross members to a length greater than a width of the container.

9. The method as claimed in claim 8 further comprising the step of moving the two substantially-parallel elevator supports to a position substantially parallel to the plurality of adjustable cross members.

10. The method as claimed in claim 8 further comprising a plurality of inserts having a plurality of desired heights and further comprising the step of inserting at least one of the plurality of inserts into the adjustable first support legs to increase or decrease an overall length of each of the plurality of adjustable first support legs.

11. The method as claimed in claim 8 further comprising the step of adjusting the elevator to fit the larger or smaller container.

12. An over and under line feed system having a first end and a second end comprising:

a plurality of adjustable first support legs;

a plurality of adjustable second support legs spaced from the first support legs;

a plurality of adjustable support cross members positioned between the first and second support legs;

a conveyor assembly comprising a lower conveyor and an upper conveyor; and

an elevator assembly positioned at the first end,

wherein the elevator assembly comprises spaced elevator supports connected by a support cross member, and wherein at least one of the elevator supports is connected to the first end.

13. The device as claimed in claimed 12 wherein the conveyor assembly comprises a conveyor track assembly and a plurality of indexing rails.

14. An over and under line feed system having a first end and a second end comprising:

a plurality of adjustable first support legs;

a plurality of adjustable second support legs spaced from the first support legs;

a plurality of adjustable support cross members positioned between the first and second support legs;

a conveyor assembly; and

an elevator assembly positioned at the first frame end,

wherein the elevator assembly further comprises a movable elevator having an adjustable elevator cross member, a pair of adjustable elevator support members, a pair of adjustable elevator base members, and an adjustable elevator base cross member, wherein the adjustable elevator cross member is positioned between the pair of elevator support members, and the elevator base cross member is positioned between the pair of elevator base members.
