Abstract

In embodiments, a conveyor apparatus can include a conveyor ribbon having a length, a width, a thickness less than the width, and a plurality of receiving apertures located along the length and extending through the thickness of the conveyor ribbon. The plurality of receiving apertures are dimensioned to receive and hold a plurality of glass articles. A conveyor drive and guidance system directs the conveyor ribbon along a predefined conveyor path. The predefined conveyor path can include an immersion section and a drain section. The immersion section can be oriented to direct the conveyor ribbon into and out of an immersion station and the conveyor ribbon is rotated about a horizontal axis in the drain section after being directed out of the immersion station.

First claim

The invention claimed is:

1. A method for processing a plurality of glass articles comprising:
loading and retaining a plurality of glass articles into a plurality of receiving apertures of a conveyor ribbon, the conveyor ribbon extending along a predefined conveyor path comprising an ion-exchange tank section and a drain section, the ion-exchange tank section comprising an ion-exchange tank containing molten salt and a first drum positioned within the ion-exchange tank, the drain section comprising a loop to facilitate rotating the conveyor ribbon about a horizontal axis, wherein the conveyor ribbon extends through at least a portion of the ion-exchange tank containing the molten salt in the ion-exchange tank section, wraps around and along a length of the first drum in the ion-exchange tank section, and is rotated about the horizontal axis in the drain section;
directing the conveyor ribbon with the plurality of glass articles along the ion-exchange tank section of the predefined conveyor path whereby the plurality of glass articles are submerged in the ion-exchange tank containing molten salt; and
directing the conveyor ribbon from the ion-exchange tank section to the drain section wherein the conveyor ribbon with the plurality of glass articles is rotated about the horizontal axis thereby draining molten salt from the plurality of glass articles.

2. The method of claim 1 , wherein the predefined conveyor path extends through a plurality of ion-exchange tanks and the method further comprises directing the conveyor ribbon along the predefined conveyor path and through the plurality of ion-exchange tanks.

3. The method of claim 1 , wherein each of the plurality of receiving apertures have a keyhole shape with a first portion having a first diameter and a second portion having a second diameter, the first portions dimensioned for receiving glass articles into the conveyor ribbon and the second portions dimensioned for retaining glass articles in the conveyor ribbon.

4. The method of claim 1 , wherein the conveyor ribbon comprises a top ribbon with a plurality of top ribbon apertures and a bottom ribbon with a plurality of bottom ribbon apertures, the top ribbon translatable with respect to the bottom ribbon such that the plurality of top ribbon apertures and the plurality of bottom ribbon apertures align to form the plurality of receiving apertures extending through a thickness of the conveyor ribbon.

5. The method of claim 4 , wherein the plurality of top ribbon apertures and the plurality of bottom ribbon apertures have a same diameter.

6. The method of claim 5 , wherein:
the conveyor ribbon has an open position with the plurality of top ribbon apertures coaxial with the plurality of bottom ribbon apertures and providing a first opening; and
the conveyor ribbon has a lock position with the plurality of top ribbon apertures offset from the plurality of bottom ribbon apertures and providing a second opening.

7. The method of claim 6 , wherein the first opening is dimensioned for receiving glass articles and the second opening is dimensioned for retaining glass articles.

8. The method of claim 1 , wherein each of the plurality of receiving apertures has an outer diameter and a plurality of tabs extending inwardly from the outer diameter towards an aperture center, wherein a distal end of the plurality of tabs define a generally circular opening with an inner diameter equal, the outer diameter receiving glass articles into the conveyor ribbon and the tabs retaining glass articles in the conveyor ribbon.

9. The method of claim 1 , further comprising a flange extending from a top surface of the conveyor ribbon, the flange sliding along an outer surface of the first drum when the conveyor ribbon is directed into the ion-exchange tank by winding down the first drum.

10. The method of claim 1 , further comprising a second drum within the ion-exchange tank, wherein the conveyor ribbon wraps along and down the first drum into the ion-exchange tank and wraps along and up the second drum out of the ion-exchange tank.
