Abstract

A method, product cracker, and nest are used with a derelict product having a shell covering a core. The shell has opposed front and rear faces and a sidewall having at least one pair of diagonally opposed corner-edges extending transversely between the faces, and is separable along the sidewall into a pair of covers. In the method, the front and rear faces of the product are placed in alignment with a first axis and the pair of diagonally opposed corner-edges are placed in alignment with a second axis perpendicular to the first axis. The shell is directly supported near one corner-edge of the pair of diagonally opposed corner-edges and is impacted at the other corner-edge with sufficient force to separate the covers. The alignments are maintained during the impacting. The covers and core are collected and the core is sorted out.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

The above-mentioned and other features and objects of this invention and the manner of attaining them will become more apparent and the invention itself will be better understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying figures wherein:

FIG. 1 is a perspective view of an embodiment of the derelict product cracker.

FIG. 2 is a partial enlargement of the view of FIG. 1, with some frame components deleted.

FIG. 3 is a front view of the cracker nest, ram, ram driver, and associated frame components of the cracker of FIG.

1. The ram is in the far position.

FIG. 4 is the same view as FIG. 3, but the ram is in the near position.

FIG. 5 is a perspective view of the nest of the cracker of FIG.

1.

FIG. 6 is a semi-diagrammatical cross-sectional view of the nest of FIG.

5.

FIG. 7 is a diagram of an embodiment of the method.

FIG. 8 is a semi-diagrammatical view of a one-time-use camera prior to cracking.

FIG. 9 is a semi-diagrammatical view of the camera of FIG. 8 after cracking and of a sorting step applicable to the method shown in FIG.

7.

FIG. 10 is a perspective view of another embodiment of the nest. The flap is shown in the rest position.

FIG. 11 is the same view as FIG. 10, but the flap is shown in the elevated position.

Claims

1. A method of cracking a derelict product having a shell covering a core, said shell having opposed front and rear faces and a sidewall extending between said faces, said sidewall having at least one pair of diagonally opposed corner-edges extending transversely between said faces, said shell being separable along said sidewall into a pair of covers, each said cover including one of said faces and a part of said sidewall, said method comprising:

2. The method of claim 1 further comprising:

3. The method of claim 1 further comprising sweeping has been inserted between in a direction away from said axis following said impacting.

4. The method of claim 1 further comprising, during said impacting, directly supporting said shell near one corner-edge of said pair of diagonally opposed corner-edges.

5. The method of claim 1 further comprising impelling said derelict product into said alignment with said nest axis.

6. The method of claim 5 wherein said impelling further comprises dropping said derelict product and, following said dropping, catching said derelict product in said nest; wherein said nest is an inclined nest.

7. The method of claim 5 wherein said impelling is at a velocity insufficient to cause bouncing of said derelict product.

8. The method of claim 1 further comprising, during said impacting, gripping said faces of said shell.

9. The method of claim 1 wherein said core is a circuit board.

10. The method of claim 1 wherein said sorting follows said collecting.

11. A method of cracking a derelict product having a shell covering a core, said shell having opposed front and rear faces and a sidewall extending between said faces, said sidewall having at least one pair of diagonally opposed corner-edges extending transversely between said faces, said shell being separable along said sidewall into a pair of covers, each said cover including one of said faces and a part of said sidewall, said method comprising:

12. The method of claim 11 wherein said corner-edges define a nest axis following said impelling and said method further comprises, during said impacting, holding said derelict product in alignment with a transverse axis perpendicular to said nest axis.

13. The method of claim 11 wherein said sweeping is in a direction outward from said nest and transverse axes.

14. The method of claim 11 wherein said impelling further comprises dropping said derelict product at a maximum velocity insufficient to cause bouncing of said derelict product in said nest.
