Abstract

A transfer apparatus ( 1 ) for transferring a plurality of discrete articles ( 3 ) between a first location and a second location is disclosed. The apparatus comprises a transfer beam ( 9 ) comprising at least one article receiving means ( 10 ), adapted to be positioned adjacent the first location ( 7 a ) to receive at least one article. The transfer beam is also adapted to be adjacent the second location ( 7 b ) to discharge the at least one article. First and second bridging conveyors ( 12 a; 12 b ) are located adjacent the second location and spaced apart such that the transfer beam is movable between the first and second bridging conveyors. A method of transferring articles using such an apparatus is also disclosed. Preferably the articles are abrasive discs.

First claim

1 . Transfer apparatus for transferring a plurality of discrete articles between a first location and a second location, the apparatus comprising:
a transfer beam comprising at least one article receiving means, adapted to be positioned adjacent the first location to receive at least one article and adjacent the second location to discharge the at least one article; and first and second bridging conveyors located adjacent the second location and spaced apart such that the transfer beam is movable between the first and second bridging conveyors.

2 . Apparatus of claim 1 , wherein the transfer beam comprises a plurality of receiving means.

3 . Apparatus of claim 1 , wherein the transfer beam comprises an array of regularly spaced article receiving means.

4 . Apparatus of claim 3 , wherein the array is a linear arrangement of receiving means.

5 . Apparatus of claim 1 , wherein the receiving means comprises a locator.

6 . Apparatus of claim 1 , wherein the locator comprises a cylindrical post.

7 . Apparatus of claim 1 , wherein the article is an abrasive article.

8 . Apparatus of claim 1 , wherein the article is an abrasive disc.

9 . Method of transferring a plurality of discrete articles between a first location and a second location, the method comprising:
delivering a plurality of discrete articles to a first location; positioning a transfer beam comprising at least one article receiving means adjacent the first location; receiving at least one article onto the receiving means; positioning the transfer beam adjacent a second location; moving the transfer beam between first and second bridging conveyors located adjacent the second location, and spaced apart such that the transfer beam is movable between the first and second bridging conveyors; discharging the at least one article from the article receiving means onto the first and second bridging conveyors.

10 . Method of claim 9 , wherein the step of discharging the at least one article comprises lowering the transfer beam relative to the first and second bridging conveyors such that the at least one article remains on the first and second bridging conveyors.

11 . Method of claim 9 , further comprising the step of:
moving the transfer beam after discharging the at least one article back to be adjacent to the first location.

12 . Method of claim 9 , wherein the plurality of discrete articles is delivered to the first location on a conveyor.

13 . Method of claim 12 , wherein the method further comprises:
picking the at least one article up from the conveyor; moving the at least one article to be adjacent the receiving means; and dropping the at least one article onto the receiving means.

14 . Method of claim 9 , wherein the transfer beam comprises an array of regularly spaced article receiving means.

15 . Method of claim 14 , wherein the array is a linear arrangement of receiving means.

16 . Method of claim 9 , wherein the receiving means comprises a cylindrical post.

17 . Method of claim 9 , wherein the article is an abrasive article.
