Abstract

The present disclosure relates to an axle retainer and associated conveyor system. An example axle retainer is defined by a housing that includes a first surface configured to be secured to an inner-sidewall of a conveyor frame and a second surface opposite the first surface. The second surface defines two or more apertures configured to mount a conveyor roller axle therein. Each aperture includes a snap-fit bracket defining two arms each with a corresponding protrusion. The two arms of the snap-fit bracket are configured to expand from a first position to a second position within the aperture to receive a conveyor roller axle and rebut from the second position to the first position such that the pair of corresponding protrusions defined by the two arms of the snap-fit bracket retain the conveyor roller axle in the aperture.

First claim

What is claimed is:

1. An axle retainer comprising a housing, the housing comprising:
a first surface configured to be secured to an inner-sidewall of a conveyor frame, wherein the first surface comprises:
a locking hook on the first surface of the housing, wherein the locking hook is configured to be mounted on a groove seat at the inner-sidewall of the conveyor frame, and
an inverted hook on the first surface of the housing, wherein the inverted hook is configured to be inserted within a hook groove at the inner-sidewall of the conveyor frame, and wherein the inverted hook is inserted within the hook groove such that a pair of flaps of the inverted hooks rest against an outer-sidewall of the conveyor frame; and

a second surface opposite the first surface, wherein the second surface defines:
an aperture configured to mount a conveyor roller axle therein, wherein the aperture comprises:
a snap-fit bracket comprising two arms each with a corresponding protrusion, wherein each arm of the two arms of the snap-fit bracket are configured to:
expand from a first position to a second position within the aperture to receive the conveyor roller axle, and
rebut from the second position to the first position such that the pair of corresponding protrusions defined by the two arms of the snap-fit bracket retain the conveyor roller axle in the aperture.

2. The axle retainer of claim 1 , wherein the first surface of the axle retainer is configured to be clamped between two ends of adjacent conveyor zones defined by one or more frame-walls of a conveyor frame.

3. The axle retainer of claim 1 , wherein each arm of the two arms of the snap fit bracket are further configured to:
expand from the first position to the second position within the aperture for dismounting the conveyor roller axle from the aperture; and
rebut to the first position from the second position in an instance in which the conveyor roller axle is dismounted from the aperture.

4. The axle retainer of claim 1 , wherein the second surface of the housing further comprises at least one channel for receiving a transition plate.

5. The axle retainer of claim 1 , wherein the aperture comprises a supporting arm configured to support the conveyor roller axle mounted in the aperture.

6. The axle retainer of claim 3 , wherein the inverted hook includes a protrusion or the pair of flaps extending away from each other.

7. The axle retainer of claim 1 , wherein the locking hook on the first surface of the housing includes a hex shaped protrusion to receive the complementary shaped groove seat.

8. A conveyor system with one or more axle retainers comprising:
a conveyor frame defining a first frame-wall and a second frame-wall; and
the one or more axle retainers secured to an inner side-wall of the first frame-wall and the second frame-wall, the one or more axle retainers defined by a housing comprising:
a first surface configured to be secured to the inner-side wall of the first frame-wall and the second frame-wall, wherein the first surface comprises:
a locking hook on the first surface of the housing, wherein the locking hook is configured to be mounted on a groove seat at the inner-sidewall of the first frame-wall and the second frame-wall, and
an inverted hook on the first surface of the housing, wherein the inverted hook is configured to be inserted within a hook groove at the inner-sidewall of the first frame-wall and the second frame-wall, and wherein the inverted hook is inserted within the hook groove such that a pair of flaps of the inverted hooks rest against an outer-sidewall of the first frame-wall and the second frame-wall;

an aperture configured to mount a conveyor roller axle therein, wherein the aperture comprises:
a snap-fit bracket comprising two arms each with a corresponding protrusion, wherein each arm of the two arms of the snap-fit bracket are configured to:
expand from a first position to a second position within the aperture to receive the conveyor roller axle, and
rebut from the second position to the first position such that the pair of corresponding protrusions defined by the two arms of the snap-fit bracket retain the conveyor roller axle in the aperture.

9. The conveyor system of claim 8 , wherein the conveyor frame is divided into a plurality of conveyor zones, wherein each conveyor zone comprises a set of conveyor rollers mounted between the first frame-wall and the second frame-wall of the conveyor frame and, wherein a conveyor belt is reeved over the set of conveyor rollers.

10. The conveyor system of claim 9 , wherein at least one of the one or more axle retainers is clamped between two ends of adjacent conveyor zones on the first frame-wall or the second frame-wall of the conveyor frame.

11. The conveyor system of claim 8 , wherein at least one of the first frame-wall and the second frame-wall of the conveyor frame comprises the groove seat configured to engage with the locking hook of the one or more axle retainers for securing the one or more axle retainers on the first frame wall or the second frame-wall, respectively.

12. The axle retainer of claim 11 , wherein the flaps are made of a flexible material.

13. The conveyor system of claim 8 , wherein at least one of the first frame-wall and the second frame-wall of the conveyor frame comprises the hook groove configured to receive the inverted hook of the one or more axle retainers for securing the one or more axle retainers on the first frame-wall or the second frame wall, respectively.

14. A method of coupling a conveyor roller axle to a conveyor frame, the method comprising:
securing, a first surface of an axle retainer to an inner-sidewall of the conveyor frame, wherein the axle retainer includes a second surface opposite to the first surface, wherein the first surface comprises:
a locking hook on the first surface of the housing, wherein the locking hook is configured to be mounted on a groove seat at the inner-sidewall of the conveyor frame, and
an inverted hook on the first surface of the housing, wherein the inverted hook is configured to be inserted within a hook groove at the inner-sidewall of the conveyor frame, and wherein the inverted hook is inserted within the hook groove such that a pair of flaps of the inverted hooks rest against an outer-sidewall of the conveyor frame; and

mounting, the conveyor roller axle to an aperture of the second surface, wherein the aperture includes a snap-fit bracket comprising two arms each with a corresponding protrusion, the mounting comprises:
expanding, of the two arms, from a first position to a second position within the aperture to receive the conveyor roller axle, and
rebutting, of the two arms, from the second position to the first position such that the pair of corresponding protrusions defined by the two arms of the snap-fit bracket retain the conveyor roller axle in the aperture.

15. The method of claim 14 , further comprising clamping the first surface between two ends of adjacent conveyor zones defined by one or more frame-walls of the conveyor frame.

16. The method of claim 14 , further comprising the second surface of the axle retainer comprising of at least one channel for receiving a transition plate.

17. The method of claim 14 , further comprising the locking hook on the first surface of the housing includes a hex shaped protrusion to receive the complementary shaped groove seat.

18. The method of claim 14 , further comprising the transition plate covering the open spaces between the axle retainer and the conveyor frame.
