Abstract

A packaging machine (10) includes a lane assembly (12) that includes one or more lanes (L) which guide cylindrical articles (B), such as cans or bottles, across a series of substantially parallel conveyors. The lane assembly (12) includes an adjustable guide bar (34) which defines an adjustable portion (V) of the lane (L) that can be adjusted to adapt to the diameter of articles (B). The lane assembly (12) also includes lane extensions (70) that can be adjusted to control the position of rows of articles (B) as the articles (B) exit the lanes (L) onto a conveyor (20).

Claims

1. A packaging machine (10), comprising:

a plurality of substantially parallel lanes (L) each for guiding articles (B) from and infeed end to an outfeed end thereof, said lanes (L) being defined with respect to one another by an inside lane guide (32) and an outside lane guide (33); and

a lane extension (70) telescopingly mounted at the outfeed end of each of said lanes (L), wherein each said lane extension (70) is selectively extendable and retractable to modify the length of said outside lane guide (33).

2. The packaging machine of claim 1, further comprising a pocket conveyer (20) for receiving articles (B) exiting said lanes (L);

wherein;

said articles (B) are deposited onto said pocket conveyor (20); and

each said lane extension is capable of extending above said pocket conveyor (20) such that the degree of extension of each said lane extension (70) controls the position at which said articles (B) are deposited.

3. The packaging machine of claim 2, wherein said pocket conveyor (20) travels in a direction of flow (F) and said lanes (L) are angled with respect to said direction of flow (F).

4. The packaging machine of claim 1, wherein each said lane extension (70) is independently extendable.

5. The packaging machine of claim 1, further comprising electromechanical means for automatically adjusting the extension of said lane extensions (70).

6. The packaging machine of claim 5, wherein all of said lane extensions (70) are synchronously extendable.

7. A method for arranging articles (B) on a conveyor (70) that drives the articles (B) in a direction of flow (F), comprising:

providing a plurality of substantially parallel lanes (L) each for guiding articles (B) from and infeed end to an outfeed end thereof, said lanes (L) being defined with respect to one another by an inside lane guide (32) and an outside lane guide (33), and said lanes (L) being angled with respect to said direction of flow (F);

for each of said lanes (L), selectively controlling the degree of extension over the conveyor (70) of a lane extension (70) that is telescopingly mounted at the outfeed end of said each of said lanes (L), thereby modifying the length of said outside lane guide (33); and

wherein said degree of extension is selected according to the desired position of said articles (B) on said conveyor (70).

8. The method of claim 7, further comprising:

depositing said articles (B) on the conveyor (70) in a matrix-like arrangement having a plurality of rows each defined by articles (B) exiting a single lane; and

selecting the degree of extension of each of said lanes (L) to control the distance between adjacent ones of said rows of articles (B).

9. The method of claim 7, further comprising selecting the degree of extension of each of said lanes (L) according to the diameter of each of said articles (B).
