Abstract

A removable cartridge cleaner assembly is provided that allows for easier replacement of the belt cleaner blades from under a conveyor belt. In one aspect the assembly includes a cartridge assembly configured for connection with at least one belt cleaner blade assembly and a support assembly configured to support the cartridge assembly across a transverse width of the conveyor belt. A releasable connection between the cartridge assembly and the support assembly is configured to be sheltered from dust and debris. The releasable connection may be disposed within a chamber formed by the engaging portions of the cartridge and support assemblies. The releasable connection can be released by removing a longitudinally oriented rod member that extends along a length of the cartridge and support assemblies. The support assembly may include a secondary cartridge support for easing installation and removal of the cartridge assembly.

First claim

What is claimed is:

1. A removable cartridge cleaner assembly for cleaning a conveyor belt, comprising:
an elongate cartridge assembly configured for having at least one cleaner blade assembly fixed thereto;
an elongate support assembly configured for supporting the elongate cartridge assembly adjacent to and across the conveyor belt in a lateral direction transverse to a longitudinal belt travel direction;
a lower engaging portion of the elongate cartridge assembly for engaging and being supported by the elongate support assembly;
a fastening projection extending from the lower engaging portion of the elongate cartridge assembly, the fastening projection including a through-opening extending in the lateral direction;
an upper engaging portion of the elongate support assembly for engaging the lower engaging portion of the elongate cartridge assembly;
at least one opening in the upper engaging portion of the elongate support assembly for receiving the fastening projection of the elongate cartridge assembly; and
an elongate rod member configured to be received in the through-opening of the fastening projection to extend along the lateral direction for securing the elongate cartridge assembly to the elongate support assembly.

2. The removable cartridge cleaner assembly of claim 1 , wherein the fastening projection comprises a plurality of fastening projections extending from the lower engaging portion of the elongate cartridge assembly, the plurality of fastening projections including a plurality of corresponding through-openings therein, wherein the through-openings are aligned along an axis extending in the lateral direction for receiving the elongate rod member therethrough.

3. The removable cartridge cleaner assembly of claim 2 , wherein the upper engaging portion of the elongate support assembly includes a plurality of spaced openings therein for receiving the plurality of fastening projections of the elongate cartridge assembly.

4. The removable cartridge cleaner assembly of claim 1 , wherein the lower engaging portion of the elongate cartridge assembly and the upper engaging portion of the elongate support assembly are mating portions having complimentary shapes such that the upper engaging portion of the elongate support assembly is in a nested configuration with the lower engaging portion of the elongate cartridge assembly when engaged therewith in the operative position for protecting the fastening projection from debris removed from the conveyor belt.

5. The removable cartridge cleaner assembly of claim 1 , wherein the elongate cartridge assembly includes first and second transversely extending leg portions comprising the lower engaging portion, and the fastening projection extends between and is connected to both the first and second leg portions.

6. The removable cartridge cleaner assembly of claim 1 , wherein the upper engaging portion of the elongate support assembly includes first and second transversely extending leg portions having an upper corner juncture therebetween with the leg portions extending transversely down and away from the corner juncture.

7. The removable cartridge cleaner assembly of claim 1 , wherein the elongate rod member is configured to be disposed within a chamber of the elongate support assembly with one or both of a first and second end portion thereof protruding therefrom.

8. The removable cartridge cleaner assembly of claim 1 , wherein the elongate support assembly includes a tube with a mounting flange disposed at each end thereof, wherein at least one of the mounting flanges includes a through-aperture aligned with the fastening projection through-opening for receiving the rod member therethrough.

9. The removeable cartridge cleaner assembly of claim 1 , wherein the elongate support assembly includes at least one secondary cartridge support disposed adjacent to the upper engaging portion for supporting the elongate cartridge assembly adjacent to the upper engaging portion in an inoperative position with the fastening projection of the elongate cartridge assembly removed from the at least one opening in the upper engaging portion of the elongate support assembly.

10. The removeable cartridge cleaner assembly of claim 9 , wherein the at least one secondary cartridge support includes a plate-like projection that extends transversely to a longitudinal axis of the elongate support assembly and is arranged and configured to support the elongate cartridge assembly in the inoperative position.

11. A removable cartridge cleaner assembly for cleaning a conveyor belt, comprising:
an elongate cartridge assembly having a length extending along a longitudinal axis, the elongate cartridge assembly configured for fixing at least one cleaner blade assembly thereto;
an elongate support assembly for supporting the elongate cartridge assembly having an elongate cartridge assembly engaging portion for engaging with and supporting the elongate cartridge assembly adjacent to and laterally across the conveyor belt;
a releasable connection of the elongate cartridge assembly to the elongate support assembly for allowing the elongate cartridge assembly to be secured to and removed from the elongate support assembly; and
a longitudinally extending chamber of at least one of the elongate cartridge assembly and the elongate support assembly that extends along the length of the elongate cartridge assembly, wherein the releasable connection extends longitudinally within the chamber such that the releasable connection is protected from fouling by conveyor belt debris released from the conveyor belt.

12. The removable cartridge cleaner assembly of claim 11 , wherein the releasable connection includes at least a portion of an elongate rod member that extends in the chamber along the length of the elongate cartridge assembly when fixing the elongate cartridge assembly to the elongate support assembly.

13. The removable cartridge cleaner assembly of claim 11 , wherein the releasable connection includes fastening projections having openings through which a common central axis extends that is aligned with or parallel to the longitudinal axis of the cartridge assembly.

14. The removable cartridge cleaner assembly of claim 11 , wherein the elongate cartridge assembly includes at least one fastening projection and the elongate support assembly includes at least one opening for receiving the at least one fastening projection of the elongate cartridge assembly.

15. The removable cartridge cleaner assembly of claim 11 , wherein the elongate support assembly includes a longitudinally extending through-opening disposed at an end of the chamber for receiving an elongate rod member therethrough to fix the elongate cartridge assembly to the elongate support assembly.

16. The removable cartridge cleaner assembly of claim 11 , wherein the chamber includes a generally triangular cross-sectional area in a plane perpendicular to the longitudinal axis.

17. A cartridge assembly for a conveyor belt cleaning assembly, comprising:
an elongate base configured for being mounted to an elongate support member, the elongate base extending along a longitudinal axis and having a belt-facing side and an opposite elongate support member-facing side;
a belt cleaner blade assembly mounted to extend from the belt-facing side of the elongate base for scraping a conveyor belt; and
at least one fastening projection extending from the support member-facing side of the elongate base, wherein the at least one fastening projection includes a through-opening having a central axis that extends longitudinally.
