Abstract

A feed unit, for example for feeding components to smoking article assembly apparatus, has a guide member ( 14 ) and a plurality of pushers ( 21 ) arranged to push components ( 2 ) along a path defined by the guide member ( 14 ) for output from the feed unit. The guide member ( 14 ) is arranged to separate the components ( 2 ) into separate streams ( 63, 64 ) according to their orientation. The stream ( 63 ) of non-correctly oriented components ( 2 ) comprises a channel that is helically rotated to orientate correctly said components ( 2 ). Both streams ( 63, 64 ) converge downstream said helical section to achieve a single flow of components ( 2 ) of similar orientation.

First claim

The invention claimed is:

1. A feed unit comprising a guide member and a plurality of pushers arranged to push components along a path defined by the guide member for output from the feed unit, wherein the guide member comprises a separator arranged to separate the components into separate streams according to their orientation,
wherein the path defined by the guide member splits into a first portion and second portion to separate the components into separate streams according to their orientation, and
wherein the first portion of the path is shaped to only accept components having a first orientation and the second portion of the path is shaped to only accept components having a second orientation.

2. The feed unit of claim 1 , wherein the guide member is further arranged to rotate at least one stream of components as they are pushed along the path by the pushers.

3. The feed unit of claim 2 , wherein the guide member comprises a rotated section to rotate components being pushed through the rotated section by the pushers.

4. The feed unit of claim 2 , wherein the guide member is further arranged to recombine the separate streams of components after at least one of said separate streams has been rotated.

5. The feed unit of claim 1 , wherein the guide member comprises a surface disposed to guide components along said path.

6. The feed unit of claim 5 , wherein the guide member comprises a groove in which components are received.

7. The feed unit of claim 6 , wherein at least a part of the guide member comprises oppositely arranged grooves to define a channel through which components are pushed.

8. The feed unit of claim 7 , wherein the one or more grooves are shaped to substantially match the shape of said components.

9. The feed unit of claim 1 , wherein the first portion is shaped to accept components having a first orientation and the second portion shaped to accept components having a second orientation.

10. The feed unit of claim 1 , wherein the pushers extend across the path.

11. The feed unit of claim 10 , wherein the pushers are arranged such that a component is received in each space between adjacent pushers during use of the feed unit.

12. The feed unit of claim 1 , wherein the path directs components to a transfer drum for transfer to subsequent apparatus.

13. The feed unit of claim 1 , wherein the pushers are arranged to push the components through the separator.

14. The feed unit of claim 1 , wherein the path defined by the guide member is arcuate and the pushers are mounted to a rotary device such that the pushers follow the path as the rotary device rotates.

15. A method of feeding components to subsequent apparatus comprising pushing components along a path defined by a guide member for output to subsequent apparatus, and separating the components into separate streams according to their orientation,
wherein the path defined by the guide member splits into a first portion and second portion to separate the components into separate streams according to their orientation, and
wherein the first portion of the path is shaped to only accept components having a first orientation and the second portion of the path is shaped to only accept components having a second orientation.

16. A method of assembling an article comprising method of claim 15 and further comprising combining each said components with one or more further components to form an article.

17. An article assembled using the method of claim 16 .
