Abstract

A method of engaging a plurality of products, the method includes positioning the plurality of products on a conveyor assembly, driving the conveyor assembly to move the plurality of products in a machine direction, driving a plurality of flight assemblies in a closed path about a product engaging assembly positioned above the conveyor assembly, engaging a respective product with a respective flight assembly, and engaging the respective flight assembly with a respective cam track of a plurality of cam tracks along a cam plate of the product engaging assembly to one of maintain a rotational arrangement of a portion of the respective flight assembly or cause the portion of the respective flight assembly to rotate.

First claim

What is claimed is:

1 . A method of engaging a plurality of products, the method comprising:
positioning the plurality of products on a conveyor assembly; driving the conveyor assembly to move the plurality of products in a machine direction; driving a plurality of flight assemblies in a closed path about a product engaging assembly positioned above the conveyor assembly; engaging a respective product with a respective flight assembly; and engaging the respective flight assembly with a respective cam track of a plurality of cam tracks along a cam plate of the product engaging assembly to one of maintain a rotational arrangement of a portion of the respective flight assembly or cause the portion of the respective flight assembly to rotate.

2 . The method of claim 1 , wherein the respective flight assembly comprises a top plate and a plurality of product engaging plates rotatably coupled to the top plate, the portion of the respective flight assembly is the plurality of product engaging plates, and the plurality of product engaging plates arranged for at least partially receiving a respective product therebetween.

3 . The method of claim 2 , wherein the plurality of product engaging plates are rotatably coupled to the top plate through a pinion, the flight assembly further comprising a cam follower extending from a rack operably coupled to the pinion for causing rotation of the plurality of product engaging plates relative to the top plate.

4 . The method of claim 3 , wherein the method further comprises engaging the cam follower in the respective cam track of the plurality of cam tracks to move the rack to cause rotation of the plurality of product engaging plates relative to the top plate.

5 . The method of claim 4 , wherein the cam follower is a first cam follower and the respective flight assembly comprises a second cam follower extending from the top plate, and the method further comprises moving the first cam follower toward the second cam follower to move the rack to cause rotation of the plurality of product engaging plates relative to the top plate.

6 . The method of claim 3 , wherein each flight assembly of the plurality of flight assemblies is associated with a respective product lane of a plurality of product lanes on the conveyor assembly, the plurality of product lanes comprising a generally straight product lane extending in the machine direction and at least one curved lane at least partially diverging from the generally straight product lane.

7 . The method of claim 6 , wherein the product engaging assembly further comprises a plurality of diverter assemblies operably engaged with the cam plate, each diverter assembly comprises a diverter plate pivotably arranged relative to the cam plate and supporting at least one diverter track portion thereon.

8 . The method of claim 7 , wherein the method further comprises pivotably moving the diverter plate of a respective diverter assembly toward a discontinuity in the cam plate to align the at least one diverter track portion with a respective cam track of the plurality of cam tracks to cause the respective flight assembly to move above the at least one curved product lane.

9 . The method of claim 7 , wherein the method further comprises maintaining the mount of a respective diverter plate at least partially above the cam plate to cause the respective flight assembly to remain above the generally straight product lane.

10 . The method of claim 9 , wherein the product engaging assembly further comprises a plurality of bypass assemblies operably engaged with the cam plate, each bypass assembly comprises at least one cam track portion pivotably arranged relative to the cam plate.

11 . The method of claim 10 , wherein the method further comprises pivotably moving the at least one cam track portion of a respective bypass assembly toward a discontinuity in the cam plate to align the at least one cam track portion with a respective cam track of the plurality of cam tracks to cause the portion of the flight assembly to rotate.

12 . The method of claim 11 , wherein the method further comprises engaging the cam follower in the respective cam track of the plurality of cam tracks to move the rack to cause rotation of the plurality of product engaging plates relative to the top plate.

13 . The method of claim 12 , wherein the cam follower is a first cam follower and the respective flight assembly comprises a second cam follower extending from the top plate, and the method further comprises moving the first cam follower toward the second cam follower to move the rack to cause rotation of the plurality of product engaging plates relative to the top plate.

14 . The method of claim 10 , wherein the method further comprises maintaining the at least one cam track portion of a respective bypass assembly at least partially above the cam plate to maintain the rotational arrangement of the portion of the respective flight assembly.

15 . A system for engaging a plurality of products, the system comprising:
a conveyor assembly configured to move the plurality of products in a machine direction; and a product engaging assembly positioned above the conveyor assembly, the product engaging assembly comprising a plurality of flight assemblies for engaging a respective product of the plurality of products, the product engaging assembly comprising a cam plate and a plurality of cam tracks extending at least partially therealong, the plurality of flight assemblies movably supported along a closed path for engaging a respective cam track of a plurality of cam tracks for one of maintaining a rotational arrangement of a portion of the respective flight assembly or causing the portion of the respective flight assembly to rotate.

16 . The system of claim 15 , wherein the respective flight assembly comprises a top plate and a plurality of product engaging plates rotatably coupled to the top plate, the portion of the respective flight assembly is the plurality of product engaging plates, and the plurality of product engaging plates arranged for at least partially receiving a respective product therebetween.

17 . The system of claim 16 , wherein the plurality of product engaging plates are rotatably coupled to the top plate through a pinion, the flight assembly further comprising a cam follower extending from a rack operably coupled to the pinion for causing rotation of the plurality of product engaging plates relative to the top plate.

18 . The system of claim 17 , wherein the cam follower is configured for engagement in the respective cam track of the plurality of cam tracks to move the rack to cause rotation of the plurality of product engaging plates relative to the top plate.

19 . The system of claim 18 , wherein the cam follower is a first cam follower and the respective flight assembly comprises a second cam follower extending from the top plate, the first cam follower configured for movement toward the second cam follower to move the rack to cause rotation of the plurality of product engaging plates relative to the top plate.

20 . The system of claim 17 , wherein each flight assembly of the plurality of flight assemblies is associated with a respective product lane of a plurality of product lanes on the conveyor assembly, the plurality of product lanes comprising a generally straight product lane extending in the machine direction and at least one curved lane at least partially diverging from the generally straight product lane.
