Abstract

A conversion bracket for converting a conveyor frame to accommodate a conveyor belt. The bracket includes a base, a plurality of shaft holders extending from a first end of the base and a plurality of wearstrip receptacles extending from a second end of the base. The bracket attaches to a shaft of a conveyor frame by inserting the shaft into the shaft holders. Wearstrips are inserted into the wearstrip receptacles, which are oriented and configured so that the inserted wearstrips rest on the tops of the shaft.

First claim

What is claimed is:

1. A bracket for connecting a wearstrip to a conveyor frame shaft, comprising:
a base extending laterally from a first side to a second side;
a shaft holder comprising a protrusion extending from a first end of the base and having an opening for receiving the conveyor frame shaft;
a wearstrip receptacle on the base, the wearstrip receptacle comprising a seat for receiving a wearstrip such that a wearstrip inserted in the wearstrip receptacle will rest above a conveyor frame shaft received in the opening; and
a first containment block receptacle at the first side of the base for receiving a first containment block.

2. The bracket of claim 1 , wherein the bracket includes a plurality of shaft holders and a plurality of wearstrip receptacles.

3. The bracket of claim 1 , wherein the seat comprises a first L-shaped bracket overlapping a second L-shaped bracket.

4. The bracket of claim 3 , wherein the wearstrip receptacle includes a curved arm extending from the base and the overlapping L-shaped brackets are fastened to the curved arm.

5. The bracket of claim 1 , wherein the shaft holder further includes tabs on each side of the opening for securing a strap to hold a conveyor frame shaft in the opening.

6. The bracket of claim 1 , further comprising a second containment block receptacle at a second side of the base for receiving a second containment block.

7. A method of retrofitting a positive-drive low tension thermoplastic conveyor belt to a flat belt conveyor frame, comprising the steps of:
attaching a plurality of conversion brackets to shafts on the conveyor frame, each conversion bracket including a plurality of shaft holders and a plurality of wearstrip holders; and
inserting wearstrips into the wearstrip holders, such that the wearstrips rest on the tops of the shafts.

8. The method of claim 7 , further comprising the step of:
inserting containment blocks into containment block receptacles on the conversion brackets.

9. The method of claim 7 , further comprising the step of securing the shafts in the shaft holders.

10. The method of claim 7 , wherein the wearstrip holders comprises a first L-shaped bracket overlapping a second L-shaped bracket.

11. The method of claim 10 , wherein the wearstrip receptacle includes a curved arm and the overlapping L-shaped brackets are fastened to the curved arm.

12. The method of claim 7 , further comprising the step of connecting ends of serial wearstrips using a wearstrip connector.

13. The method of claim 12 , wherein the wearstrip connector comprises two halves that mate to form a seat for the ends of the wearstrips.

14. A conveyor frame, comprising:
a central spine extending from a first end to a second end;
a plurality of shafts extending from the central spine;
a plurality of brackets attached to selected shafts;
a plurality of wearstrips inserted into wearstrip holders on the brackets such that the wearstrips rest on the tops of the shafts; and
containment blocks inserted in containment block receptacles on the brackets.
