Abstract

A method and apparatus for transferring discrete articles such as eggs or fruit from a conveyor having at least one row of article holders to a receiver having a resilient upwardly facing portion which then carries the articles generally horizontally to a receiving station. The upwardly facing portion has a resilient structure including for example brush bristles or an air bellows.

Claims

1. An apparatus for transferring discrete articles, comprising:

a conveyor having at least one row of article holders for conveying articles which are spaced apart from each other in the direction of travel of the conveyor,

a resilient receiving means having an upwardly facing portion positioned beneath the conveyor for receiving articles dropped from the conveyor, the upwardly facing portion of the receiving means being moveable transversely, relative to the direction of the movement of the conveyor, in a generally horizontal direction, said upwardly facing portion having a resilient structure for resiliently receiving the articles which are dropped from the conveyor and a lateral engaging structure for engaging the sides of the articles to assure movement of the articles along with the receiving means,

and a receiving station positioned adjacent said upwardly facing portion of the receiving means downstream from the location where the articles are dropped thereon,

whereby articles delivered from the conveyor drop onto the upwardly facing portion of the receiving means, which then moves the articles therealong in a generally horizontal direction to the receiving station.

2. An apparatus according to claim 1, wherein the upwardly facing portion is long enough, in its direction of travel, to receive at least two articles, such that a plurality of articles carried by the conveyor, side by side, can be dropped simultaneously onto the upwardly facing portion of the receiving means.

3. An apparatus according to claim 1, wherein the upwardly facing portion comprises brush bristles which form the resilient structure as well as the lateral engaging structure, as the articles fall into the bristles.

4. An apparatus according to claim 3, wherein the receiving means is a cylindrical brush, the curved uppermost portion of which comprises said upwardly facing portion.

5. An apparatus according to claim 3, wherein the receiving means comprises an endless conveyor having a generally straight upper run which forms said upwardly facing portion.

6. An apparatus according to claim 5, wherein the resilient structure and the lateral engaging structure are formed by a plurality of discrete brushes which are connected side by side to the endless conveyor, such that the bristles of the discrete brushes are side by side with the bristles essentially parallel to each other when traveling along the generally straight upper run of the endless conveyor, but are capable of separating from each other at turns at the ends of the endless conveyor.

7. An apparatus according the claim 3, wherein the brush bristles are interrupted to form pockets, each pocket adapted for receiving an article or a row of articles.

8. An apparatus according to claim 3, wherein the bristles are of differing lengths to prevent the articles from sinking too deep into the brush bristles.

9. An apparatus according the claim 3, wherein the upwardly facing portion forms a plurality of channels, arranged side by side in the direction of travel of the conveyor, and rigid disc structures separating the respective channels from each other.

10. An apparatus according to claim 1, wherein the receiving means is cylindrical, the curved uppermost portion of which forms the said upwardly facing portion.

11. An apparatus according to claim 1, wherein the receiving means is an endless conveyor having a generally straight upper run which forms said upwardly facing portion.

12. An apparatus according to claim 1, wherein the upwardly facing portion forms a plurality of channels, arranged side by side in the direction of travel of the conveyor, and rigid disc structures separating the respective channels from each other.

13. An apparatus for transferring eggs, comprising:

an article conveyor having at least one row of egg holders for conveying eggs in a row, spaced apart from each other from the direction of travel of the conveyor,

a resilient receiving means comprising an endless surface and mounted for movement about a horizontal axis or horizontal axes and having brush bristles extending outwardly therefrom along its entire surface, the axis or axes being essentially parallel to the direction of travel of the article conveyor such that the receiving means moves transversely to the direction of travel of the article conveyor,

said receiving means having an upwardly facing portion positioned beneath the egg holders to receive within its brush bristles eggs dropped from the article conveyor,

and a receiving station positioned adjacent to said upwardly facing portion of the receiving means downstream from the location where the eggs are dropped thereon to receive eggs which have moved along the receiving means,

whereby eggs dropped from the article conveyor fall into the bristles of the upwardly facing portion of the receiving means, which then moves the eggs therealong in a generally horizontal direction to the receiving station.

14. An apparatus according to claim 13, wherein the receiving means is a cylindrical brush, the curved uppermost portion of which forms said upwardly facing portion.

15. An apparatus according to claim 13, wherein the receiving means comprises an endless conveyor having a generally straight upper run which forms said upwardly facing portion.

16. An apparatus according to claim 13, wherein the upwardly facing portion is long enough, in the direction of its travel, to receive at least two eggs, such that a plurality of eggs, carried by the article conveyor, side by side, can be dropped simultaneously into the bristles of the upwardly facing portion of the receiving means.

17. A method for transferring discrete articles from a conveyor to a receiving station, comprising:

conveying two rows of discrete articles along a conveyor side by side in two rows of article holders which are side by side and spaced apart from other article holders in the direction of movement of the conveyor,

releasing two articles, one from each row, side by side, simultaneously onto the upwardly facing portion of the receiver, which upwardly facing portion has a resilient structure to resiliently receive the articles and an engaging structure to engage the sides of the articles to assure their movement along the receiver, and

moving the upwardly facing portion transversely, relative to the direction of the conveyor, in a generally horizontal direction, to deliver the articles to a receiving station.

18. A method according to claim 17 wherein the receiver has brush bristles which form the resilient structure and the engaging structure which receives the articles.
