Abstract

A mounting assembly 10 for mounting a roller brush 12 onto an operating apparatus includes a mounting structure 14 configured to be mountable on the operating apparatus. The mounting structure has a through hole for receiving an idle shaft 16 that is sized to be engageable within a blind hole 42 formed in the adjacent end hub 32 of the brush 12 . The idle shaft 16 is resiliently loaded in the direction toward the brush hub 12 by a loader assembly 18 which includes a compression spring 16 acting against retaining ring 48 engaged with the idle shaft 16.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A mounting assembly for mounting a roller brush on an operating apparatus, the roller brush having an end structure with a longitudinal bore of a depth formed in the end structure of the roller brush, the roller brush moveable along a path longitudinally of its length during mounting to the mounting assembly, the mounting assembly comprising:
(a) a mounting structure configured to be mountable on an operating apparatus, the mounting structure having portions defining a longitudinal guide extending at least partially through the mounting structure;
(b) an idle shaft disposed within the guide of the mounting structure with a portion of the idle shaft projecting from the mounting structure, the projecting portion of the idle shaft engageable with a longitudinal bore of a brush end structure; and
(c) a loader assembly imposing a load on the idle shaft to urge the projecting portion of the idle shaft in an engagement direction into engagement within the longitudinal bore of the brush end structure and also enabling the idle shaft to retract toward the mounting structure in a direction opposite to the engagement direction the idle shaft within the longitudinal bore of the brush end structure under the movement of the roller brush toward the mounting structure.

2. A roller brush mounting assembly according to claim 1 , wherein the mounting structure has portions defining a recess therein for receiving the brush end structure.

3. A roller brush mounting assembly according to claim 1 , wherein the mounting housing has portions defining flanges for mounting the mounting housing to an operating apparatus.

4. A roller brush mounting assembly according to claim 1 , wherein the mounting structure is generally circular in shape and the longitudinal guide is located generally centrally relative to the mounting structure.

5. A roller brush mounting assembly according to claim 1 :
wherein the idle shaft is elongate in structure; and
wherein the loader assembly comprises a loader to apply a resilient load on the idle shaft along the length of the idle shaft in the direction of engagement of the idle shaft with the longitudinal bore of the brush end structure.

6. A roller brush mounting assembly according to claim 5 , wherein the loader assembly comprises a spring acting on the idle shaft to urge the idle shaft into engagement with the longitudinal bore of the brush end structure, the spring acting to enable the idle shaft to retract relative to the mounting structure under the movement of the roller brush toward the mounting structure.

7. A roller brush mounting assembly according to claim 6 , wherein the spring is engaged over the idle shaft, the spring having a proximal end toward the brush end structure and a distal end away from the brush end structure.

8. A roller brush mounting assembly according to claim 7 , wherein the loader assembly further comprises a loader structure extending from the mounting structure for engaging over the spring which in turn is engaged over a corresponding section of the idle shaft, the loader structure defining an abutment for the distal end of the spring.

9. A roller brush mounting assembly according to claim 8 , wherein the loader structure is configured to be removably attachable to the mounting structure.

10. A roller brush mounting assembly according to claim 9 , wherein the loader assembly further comprises a retainer engageable with the idle shaft, the retainer configured to bear against the proximal end of the spring, whereby the spring urges the idle shaft into engagement with the longitudinal bore of the brush end structure.

11. A roller brush mounting assembly according to claim 10 , wherein at least one groove is formed in the idle shaft for receiving the retainer.

12. A roller brush mounting assembly according to claim 11 , wherein a plurality of grooves are formed in the idle shaft for receiving the retainer within a selected one of the plurality of grooves.

13. A roller brush mounting assembly according to claim 6 , further comprising a retainer engageable with the idle shaft against which one end of the spring bears when urging the idle shaft into engagement with the longitudinal bore of the brush end structure.

14. A roller brush mounting assembly according to claim 13 , wherein a plurality of grooves are formed in the idle shaft for receiving the retainer in a selected one of the plurality of grooves, the retainer engaging with the adjacent end of the spring.

15. A roller brush mounting assembly according to claim 1 , wherein the idle shaft has portions defining a longitudinal bore extending therethrough, the longitudinal bore adapted to hold lubricant therein.

16. A roller brush mounting assembly according to claim 15 , further comprising a fitting disposed in communication with the longitudinal bore of the idle shaft through which lubricant is introducible into the longitudinal bore of the idle shaft.

17. A mounting assembly for mounting a roller brush on a food processing apparatus, the roller brush having an end structure with a longitudinal bore of a depth formed in the end structure of the roller brush, the mounting assembly comprising:
(a) a mounting housing configured to be mountable on a processing apparatus, the mounting housing having portions defining a bore extending at least partially through the mounting housing;
(b) an elongate idle shaft disposed within the mounting housing guide and projecting a distance from the mounting housing to be engageable with a longitudinal bore of a brush end structure;
(c) a loader assembly imposing a resilient load on the idle shaft to urge the idle shaft into engagement with the longitudinal bore of the brush end structure and enabling the idle shaft to move relative to the mounting housing in a direction opposite to the engagement of the idle shaft with the longitudinal bore of the brush end structure; and
(d) a stop acting on the idle shaft to limit the distance that the idle shaft projects from the mounting housing into engagement with the longitudinal bore of the brush end structure.

18. A roller brush mounting assembly according to claim 17 , wherein the stop is engageable with the idle shaft along different locations along the length of the idle shaft, with the location of such engagement dictating the extent to which the idle shaft projects from the mounting housing to be engageable with the longitudinal bore of the brush end structure.

19. A roller brush mounting assembly according to claim 18 , wherein the loader assembly comprises a spring acting against the stop to urge the idle shaft into engagement with the longitudinal bore of the brush end structure, the spring being compressible to enable the idle shaft to retract relative to the mounting housing under the movement of the roller brush toward the mounting housing.

20. A roller brush mounting assembly according to claim 19 , wherein the spring is engageable over the idle shaft to act against the stop and also bear against an abutment spaced from the stop, thereby to apply a load against a retainer and in turn apply a resilient load on the idle shaft along the length of the idle shaft in the direction toward the brush end structure.
