Abstract

A motor driven roller support assembly includes a motorized roller having a cylindrical outer surface that is configured to rotate, a support frame within which the roller is mounted, and a roller support connected to the support frame and engaging the outer surface of the motorized roller. The roller support may include a pair of support wheels for contacting the outer surface of the motorized roller, and include a pivot whereby the roller support is moveable relative to the support frame. The assembly may be integrated with a transfer conveyor, such as a right angle transfer having transfer blades that include belts driven by the motorized roller. The roller support engages the motorized roller in a direction that is generally opposite from the direction in which the belts engage the motorized roller to thereby counteract forces imparted by the belts on the motorized roller.

First claim

The invention claimed is:

1. A motor driven roller support assembly comprising:
a motorized roller, said motorized roller having a cylindrical outer surface with said motorized roller configured to provide driving rotation whereby said outer surface rotates;
a support frame, said motorized roller being mounted to said support frame;
a roller support, said roller support engaging said outer surface of said motorized roller;
wherein said roller support includes a pair of support wheels, and wherein said support wheels engage said outer surface of said motorized roller.

2. The assembly of claim 1 , wherein said roller support is connected to said support frame.

3. The assembly of claim 2 , wherein said roller support includes a pivot whereby said roller support is moveable relative to said motorized roller.

4. The assembly of claim 1 , wherein said support wheels have axes of rotation that are substantially parallel with the axis of rotation of said motorized roller, ands wherein the axes of rotation of said support wheels are not collinear with respect to one another.

5. The assembly of claim 1 , wherein said support wheels are mounted to a pivot plate, and wherein a pivot axle connects said pivot plate with said support frame.

6. The assembly of claim 5 , wherein said pivot plate comprises a pair of pivot plates, and wherein said support wheels are mounted between said pivot plates.

7. The assembly claim 1 , wherein said support frame includes a cross member and wherein said roller support is mounted to said cross member.

8. The assembly of claim 7 , wherein said support frame includes a pair of side frame members and wherein said motorized roller is mounted to and between said side frame members, and wherein said side frame members are connected to said cross member.

9. The assembly of claim 8 , further including a pair of roller shaft mounts, and wherein said roller shaft mounts connect to respective ends of said motorized roller to mount said motorized roller to said side frame members.

10. The assembly of claim 8 , further including a pair of mounting plates, each said mounting plate being connected to a respective one of said side frame members, wherein said mounting plates connect to respective ends of said motorized roller to mount said motorized roller to said side frame members.

11. The assembly of claim 1 , wherein said motorized roller includes either one or two internal motors within a cylindrical tube of said motorized roller.

12. A transfer conveyor, said transfer conveyor comprising:
a frame to which rollers are mounted, with said rollers oriented to convey items in a first direction;
a platform disposed beneath said rollers, said platform configured to being raised and lowered relative to said rollers;
a transfer blade mounted to said platform, said transfer blade including a belt, and wherein said transfer blade is configured to be extended upwards between said rollers with said belt being driven and configured to convey items in a second direction; and
a motor driven roller support assembly, said motor driven roller support assembly comprising a motorized roller, a support frame, and a roller support;
wherein said motorized roller has a cylindrical outer surface with said motorized roller being mounted to said support frame and configured to provide driving rotation whereby said outer surface rotates, and wherein said belt engages said outer surface of said motorized roller whereby said motorized roller imparts driving motion to said belt, and wherein said roller support engages said outer surface of said motorized roller.

13. The transfer conveyor of claim 12 , wherein said transfer blade has a longitudinal orientation extending with the direction of movement of said belt, and wherein the longitudinal orientation of said transfer blade is oriented perpendicularly to the axis of rotation of said motorized roller.

14. The transfer conveyor of claim 12 , wherein said transfer conveyor comprises two said transfer blades, and wherein said belts of said transfer blades contact said outer surface of said motorized roller on opposite sides of said roller support relative to the longitudinal length of said motorized roller.

15. The transfer conveyor of claim 12 , wherein said belt of said transfer blade engage said outer surface of said motorized roller in a generally diametrically opposite orientation relative to the engagement of said roller support with said motorized roller.

16. The transfer conveyor of claim 12 , wherein between two to eight transfer blades are mounted to said platform.

17. The transfer conveyor of claim 12 , wherein said transfer conveyor comprises a right angle transfer with said second direction being orthogonal to said first direction.

18. The transfer conveyor of claim 17 , further comprising a plurality of rollers upon which objects are configured to be moved with said platform disposed beneath said rollers, and wherein a plurality of transfer blades are mounted to said platform with said platform configured to be raised to extend each said transfer blade between a pair of said rollers.

19. The transfer conveyor of claim 12 , wherein said roller support is connected to said support frame with said roller support including a pivot whereby said roller support is moveable relative to said support frame, and wherein said roller support includes a pair of support wheels that engage said outer surface of said motorized roller, and wherein said support wheels have axes of rotation that are substantially parallel with the axis of rotation of said motorized roller.

20. A motor driven roller support assembly comprising:
a motorized roller, said motorized roller having a cylindrical outer surface with said motorized roller including an internal motor configured to provide driving rotation whereby said outer surface rotates;
a support frame, said motorized roller being mounted to said support frame; and
a roller support, said roller support including a support wheel;
wherein said support wheel engages said outer surface of said motorized roller.

21. The assembly of claim 20 , wherein said roller support includes a pair of support wheels that both engage said outer surface of said motorized roller, and wherein said roller support includes a pivot whereby said support wheels are moveable relative to said motorized roller.
