Abstract

A method of forming bundles of glass articles is provided. The method includes transporting individual glass articles to an insert building station using a conveying system. The glass articles are individually located within article receiving slots of a layer separation insert using the conveying system. Each slot of the layer separation insert receives a single glass article forming a glass article layer of side-by-side glass articles. Multiple glass article layers including layer separation inserts are stacked using the conveying system forming a bundle. The layer separation inserts provide a barrier between adjacent glass articles of each of the glass article layers to inhibit glass-to-glass contact.

First claim

What is claimed is:

1. A method of forming bundles of glass articles, the method comprising:
transporting individual glass articles to an insert building station using a conveying system, the conveying system comprising a continuous conveyor belt comprising sectioned article retaining regions that are each sized and configured to retain a single glass article spaced from adjacent glass articles in a conveying direction as the glass articles are transported to the insert building station;
moving a layer separation insert to the insert building station using a conveyor different from the continuous conveyor belt;
individually locating the glass articles within article receiving slots of the layer separation insert using the continuous conveyor belt and the conveyor, wherein each article receiving slot of the layer separation insert sequentially receives a single glass article that is released from a respective sectioned article retaining region of the continuous conveyor belt forming a glass article layer of side-by-side glass articles;
moving the layer separation insert with the glass articles from the insert building station to a bundle building station using the conveyor once the layer separation insert is filled; and
using a robotic lift assembly, removing the layer separation insert with the glass articles from the conveyor and stacking multiple glass article layers including layer separation inserts using the conveying system forming a bundle, the layer separation inserts providing a barrier between adjacent glass articles of each of the glass article layers.

2. The method of claim 1 , wherein the glass articles are in the form of glass tubes, the method further comprising detecting if any of the article receiving slots are unfilled using a sensor before the step of moving the layer separation insert with the glass articles from the insert building station to the bundle building station.

3. The method of claim 2 further comprising individually locating the glass tubes in multiple layer separation inserts using the conveying system forming a glass article layer of side-by-side glass tubes.

4. The method of claim 1 further comprising wrapping the bundle with a plastic film.

5. The method of claim 1 further comprising forming the bundle within a shipping container.

6. The method of claim 1 , wherein the layer separation inserts comprise sidewalls that separate adjacent slots.

7. An apparatus that forms bundles of glass articles, the apparatus comprising:
a glass article infeed station that provides glass articles to a conveying system, the conveying system transports individual glass articles to an insert building station, the conveying system comprising a continuous conveyor belt comprising sectioned article retaining regions that are each sized and configured to retain a single glass article spaced from adjacent glass articles in a conveying direction as the glass articles are transported to the insert building station;
an insert feed station comprising a plurality of layer separation inserts, the conveying system transports the plurality of layer separation inserts to the insert building station;
the conveying system is configured to individually locate the glass articles within article receiving slots of the plurality of layer separation inserts using the continuous conveyor belt, wherein each article receiving slot of the plurality of layer separation inserts sequentially receives a single glass article that is released from a respective sectioned article retaining region of the continuous conveyor belt forming a glass article layer of side-by-side glass articles;
a bundle building station where the conveying system stacks multiple glass article layers including layer separation inserts forming a bundle, the layer separation inserts providing a barrier between adjacent glass articles of each of the glass article layers;
a conveyor different from the continuous conveyor belt that moves each one of the plurality of layer separation inserts from the insert building station to the bundle building station once each one of the plurality of layer separation inserts is filled; and
a robotic lift assembly that removes each one of the plurality of layer separation inserts with the glass articles from the conveyor and stacks the multiple glass article layers.

8. The apparatus of claim 7 , wherein the glass articles are in the form of glass tubes, the apparatus further comprising a sensor that is used to detect if any of the article receiving slots are unfilled before the conveyor moves each one of the plurality of separation inserts from the insert building station to the bundle building station.

9. The apparatus of claim 8 , wherein the conveying system simultaneously transports multiple ones of the layer separation inserts to the insert building station, each glass article being received by slots of the multiple ones of the layer separation inserts forming the glass article layer of side-by-side glass tubes.

10. The apparatus of claim 7 further comprising a film supply and seal station that wraps the bundle with a plastic film.

11. The apparatus of claim 10 comprising a heating station that heats the plastic film.

12. The apparatus of claim 7 , wherein the conveying system stacks the multiple glass article layers in a shipping container.

13. The apparatus of claim 7 , wherein the plurality of layer separation inserts comprise sidewalls that separate adjacent slots.

14. The apparatus of claim 7 , wherein the conveying system comprises a robotic lift assembly that stacks the multiple glass article layers.

15. A method of forming a palletized package of bundles of glass articles, the method comprising:
building multiple glass article layers using a conveying system by individually locating the glass articles sequentially within article receiving slots of multiple layer separation inserts using a continuous conveyor belt, the continuous conveyor belt comprising sectioned article retaining regions that are each sized and configured to retain a single glass article spaced from adjacent glass articles in a conveying direction as the glass articles are transported by the conveying system, wherein each article receiving slot of the layer separation inserts sequentially receives a single glass article that is released from a respective section article retaining region forming glass article layers of side-by-side glass articles;
moving each layer separation insert with the glass articles from the insert building station to a bundle building station using a conveyor different from the continuous conveyor belt once each layer separation insert is filled;
using a robotic lift assembly, removing each layer separation insert from the conveyor and stacking multiple glass article layers including layer separation inserts using the conveying system forming multiple bundles at the bundle building station, the layer separation inserts providing a barrier between adjacent glass articles of each of the glass article layers; and
stacking the multiple bundles forming the palletized package.

16. The method of claim 15 , wherein the glass articles are in the form of glass tubes, the method further comprising detecting if any of the article receiving slots are unfilled before the step of moving each layer separation insert with the glass articles from the insert building station to the bundle building station using the conveyor.

17. The method of claim 15 further comprising wrapping the multiple bundles with a plastic film.

18. The method of claim 15 further comprising forming
