Abstract

A conveyor including a plurality of individual conveyor units associated with a common conveyor frame and adapted for independent lateral and vertical position adjustment. The conveyor units form independent conveyors capable of conveying an object. The position of each conveying unit is adjustable along the conveyor frame in a direction substantially transverse to the conveying direction. The height of each conveying unit is also independently adjustable. Consequently, the conveying units may be arranged to form overall conveying surfaces of different configuration. The conveyor may also include a frame lift assembly capable of simultaneously and uniformly raising or lowering one end of all the conveyor units present.

Claims

1. An adjustable multi-lane conveyor, comprising:

a conveyor frame;

a plurality of individual conveying units, each conveying unit including a conveying unit frame, a conveyor belt, and a drive means for driving said conveyor belt, said conveying units movably coupled to said conveyor frame;

a lateral positioning assembly associated with said conveying units, said lateral positioning assembly operative to laterally displace an associated conveying unit with respect to a centerline of said conveyor frame; and

a vertical positioning assembly associated with each conveying unit, said vertical positioning assembly operative to vertically displace an associated conveying unit with respect to the ground;

wherein, the lateral and vertical position of each conveying unit is independently adjustable to allow for the formation of different conveyor configurations.

2. The conveyor of claim 1, further comprising a conveyor sub-frame residing between said conveyor frame and said conveying unit frames, said conveying units movably coupled to said conveyor sub-frame.

3. The conveyor of claim 1, wherein each lateral positioning assembly is slidably associated with said conveyor sub-frame.

4. The conveyor of claim 3, wherein said lateral positioning assembly includes a motor, a threaded drive shaft coupled to said motor and passing through a clutch/brake device of each conveying unit, said clutch/brake devices operative to selectively couple and decouple associated conveying units to/from said drive shaft.

5. The conveyor of claim 1, wherein each vertical positioning assembly is disposed between said conveyor sub-frame and the frame of an associated conveying unit.

6. The conveyor of claim 1, wherein each vertical positioning assembly includes a motor coupled to a central lift mechanism by a ball screw, and a pair of outwardly disposed lift mechanisms located near opposite ends of each conveying unit, said outwardly disposed lift mechanisms coupled to said central lift mechanism by associated linkage rods such that said linkage mechanisms are uniformly raised or lowered by operation of said motor.

7. The conveyor of claim 1, further comprising a frame lift assembly for simultaneously and uniformly raising or lowering one end of all of said conveying units.

8. The conveyor of claim 7, wherein each frame lift assembly is disposed between said conveyor frame and said conveyor sub-frame.

9. The conveyor of claim 8, wherein each frame lift assembly includes a motor and an associated jack screw that is extended or retracted by operation of said motor.

10. The conveyor of claim 1, wherein all of said conveying units are used to convey an object of interest.

11. The conveyor of claim 1, wherein only certain ones of said conveying units are used to convey an object of interest.

12. An adjustable multi-lane conveyor, comprising:

a conveyor frame;

a plurality of individual conveying units, each conveying unit including a conveying unit frame, a conveyor belt, and a drive means for driving said conveyor belt;

a conveyor sub-frame residing between said conveyor frame and said conveying unit frames, said conveying units movably associated with said conveyor sub-frame;

a lateral positioning assembly associated with said conveying units, said lateral positioning assembly including a motor coupled to a drive shaft that passes through each conveying unit, said lateral positioning assembly operative to laterally displace an associated conveying unit with respect to a centerline of said conveyor frame; and

a vertical positioning assembly associated with each conveying unit, each vertical positioning assembly disposed between said conveyor sub-frame and the frame of an associated conveying unit and operative to vertically displace an associated conveying unit with respect to the ground;

wherein, the lateral and vertical position of each conveying unit is independently adjustable to allow for the formation of different conveyor configurations.

13. The conveyor of claim 12, wherein said lateral positioning assembly includes a motor, a threaded drive shaft coupled to said motor and passing through a clutch/brake device of each conveying unit, said clutch/brake devices operative to selectively couple and decouple associated conveying units to/from said drive shaft.

14. The conveyor of claim 12, wherein each vertical positioning assembly is disposed between said conveyor sub-frame and the frame of an associated conveying unit.

15. The conveyor of claim 12, wherein each vertical positioning assembly includes a motor coupled to a central lift mechanism by a ball screw, and a pair of outwardly disposed lift mechanisms located near opposite ends of each conveying unit, said outwardly disposed lift mechanisms coupled to said central lift mechanism by associated linkage rods such that said linkage mechanisms are uniformly raised or lowered by operation of said motor.

16. The conveyor of claim 12, further comprising a frame lift assembly for simultaneously and uniformly raising or lowering one end of all of said conveying units.

17. The conveyor of claim 16, wherein each frame lift assembly includes a motor and an associated jack screw that is extended or retracted by operation of said motor.

18. An adjustable multi-lane conveyor, comprising:

a conveyor frame;

a plurality of individual conveying units, each conveying unit including a conveying unit frame, a conveyor belt, and a drive means for driving said conveyor belt;

a conveyor sub-frame residing between said conveyor frame and said conveying unit frames, said conveying units slidably associated with said conveyor sub-frame;

a lateral positioning assembly associated with said conveying units, said lateral positioning assembly including a motor, a threaded drive shaft coupled to said motor and passing through a clutch/brake device of each conveying unit, said clutch/brake devices operative to selectively couple and decouple associated conveying units to/from said drive shaft, said lateral positioning assembly operative to laterally displace a selected conveying unit with respect to a centerline of said conveyor frame; and

a vertical positioning assembly associated with each conveying unit, each vertical positioning assembly disposed between said conveyor sub-frame and the frame of an associated conveying unit and including a motor coupled to a central lift mechanism by a ball screw and a pair of outwardly disposed lift mechanisms located near opposite ends of each conveying unit, said outwardly disposed lift mechanisms coupled to said central lift mechanism by associated linkage rods such that said linkage mechanisms are uniformly raised or lowered by operation of said motor, said vertical positioning assembly operative to vertically displace an associated conveying unit with respect to the ground;

wherein, the lateral and vertical position of each conveying unit is independently adjustable to allow for the formation of different conveyor configurations.

19. The conveyor of claim 18, further comprising a frame lift assembly for simultaneously and uniformly raising or lowering one end of all of said conveying units.

20. The conveyor of claim 19, wherein each frame lift assembly includes a motor and an associated jack screw that is extended or retracted by operation of said motor.
