Abstract

A hot glass sheet processing system includes a roller conveyor (22) having sintered bonded fused silica rollers (24) and a roller support structure (34) located within a heated location (32) together with an elongated cooling unit (36) having a housing (38) defining a cooling chamber (40) that receives and has bearings (42) that rotatably support an aligned set of roller ends (30) having end caps (86) adhesively bonded to the roller ends. The cooling unit includes a cooling circuit that supplies cooling fluid to the cooling chamber (40) to provide cooling of the aligned set of roller ends (30) and the bearings (42).

First claim

What is claimed is:

1. In a hot glass sheet processing system, the invention comprising:
a roller conveyor extending along a direction of conveyance of the processing system and including a plurality of rollers made of sintered bonded fused silica and having a set of roller ends that are located within a heated location of the system and aligned with each other along the direction of conveyance, and the roller ends having associated end caps secured thereto by an adhesive; and
a roller support structure located within the heated location of the system and having an elongated cooling unit including a housing defining a cooling chamber that receives and has bearings that rotatably support the end caps of the aligned set of roller ends, and the cooling unit including a fluid cooling circuit that supplies cooling fluid to the cooling chamber to provide cooling of the aligned set of roller ends and cooling of the bearings.

2. The invention of claim 1 wherein the fluid cooling circuit is a liquid cooling circuit for the aligned set of roller ends and the bearings.

3. The invention of claim 2 wherein the fluid cooling circuit is a water cooling circuit for the aligned set of roller ends and the bearings.

4. The invention of claim 3 wherein the fluid cooling circuit is a water and an antifreeze cooling circuit for the aligned set of roller ends and the bearings.

5. In a hot glass sheet processing system, the invention comprising:
a roller conveyor extending along a direction of conveyance of the processing system and including a plurality of rollers made of sintered bonded fused silica and having a set of roller ends that are located within a heated location of the system and aligned with each other along the direction of conveyance, and the roller ends having associated end caps secured thereto by an adhesive;
a roller support structure located within the heated location of the system and having an elongated cooling unit including a housing defining a cooling chamber that receives and has bearings that rotatably support the end caps of the aligned set of roller ends, and the cooling unit including a liquid cooling circuit that supplies cooling liquid to the cooling chamber to provide cooling of the end caps of the aligned set of roller ends and cooling of the bearings; and
an air supply that prevents heated air in the processing system from flowing into the cooling unit and heating the aligned set of roller ends and the bearings.
