Abstract

An improved egg handling device is disclosed in which a number of egg lifting vacuum cups, mounted on a convenient support, are used both to transfer eggs and to punch the egg shells. The egg piercing system is incorporated with the transfer cups to provide for a simultaneous piercing and lifting of the eggs. A piercing needle is mounted within each vacuum cup in a position to pierce or puncture each egg shell while it is held within the cup by the vacuum lifting force.

Claims

1. An improved vacuum egg handling means comprising the combination of:

a vacuum support means for receiving and supporting eggs;

means for connecting said support means to a source of vacuum;

punch means positioned on said support means for punching an aperture in the shells of eggs held by said support means; and

said connecting means including means for controlling the vacuum such that said eggs as a result of said vacuum are forced into engagement with said punch means.

2. A vacuum egg handling means as set forth in claim 1 in which said vacuum support means comprises a plurality of resilient and flexible hollow cup members having air outlets communicating with said connecting means.

3. A vacuum egg handling means as set forth in claim 2 in which said punch means comprises a needle-like punch member positioned within the vacuum cup means adjacent to said air outlet.

4. A vacuum egg handling means as set forth in claim 1 in which said vacuum support means comprises a hollow support member and a plurality of resilient and flexible cups mounted in a row on said member, and means for attaching each of said cups to said member including an air conduit coupling the interiors of said cups to the interior of said hollow support member.

5. A vacuum egg handling means as set forth in claim 4 in which said means for attaching said cups to said support member comprises a mounting stud for each of said cups including said air conduit and means for engaging the cups.

6. A vacuum egg handling means as set forth in claim 1 which further comprises a gripping handle positioned on said support means, and a vacuum release switch positioned adjacent to said handle and having an air outlet coupled to said connecting means, and valve means for opening said air inlet.

7. A vacuum egg handling means as set forth in claim 1 in which said vacuum support means comprises a plurality of resilient and flexible cups having bellows in the side walls of each cup.

8. A vacuum lifter as set forth in claim 1 which further comprises switch means in said connecting means for controlling the vacuum egg support force.
