Abstract

A nail plater apparatus includes at least one nail plate magazine configured to hold a plurality of nail plates, and at least one nail plate extractor assembly associated with the at least one nail plate magazine and configured to position at least one nail plate therefrom to at least one nail plate pressing area. A board feeder is configured to position a board to a board receiving area. At least one nail plate presser assembly is adjacent the board receiving area and aligned with the at least one nail plate pressing area and configured to press the at least one nail plate into the board.

First claim

That which is claimed:

1. A nail plater apparatus comprising:
a pair of nail plate magazines configured to hold a plurality of nail plates;
a pair of nail plate extractor assemblies associated with said pair of nail plate magazines and configured to position nail plates therefrom to respective nail plate pressing areas;
a board feeder configured to position a board to a board receiving area; and
a pair of nail plate presser assemblies adjacent the board receiving area and aligned with the respective nail plate pressing areas, and configured co press the nail plates into the board.

2. The nail plate apparatus according to claim 1 , further comprising a board magazine configured to hold a plurality of boards, and wherein said board feeder and said pair of nail plate extractor assemblies are linked together so that the board is positioned in the board receiving area simultaneously when the nail plates are positioned in the respective nail plate pressing areas.

3. The nail plater apparatus according to claim 1 , further comprising a board magazine configured to hold a plurality of boards, and wherein said board feeder comprises a pair of extractors, and wherein said pair of nail plate extractor assemblies comprises a pair of nail plate extractors.

4. The nail plater apparatus according to claim 3 , further comprising:
a pair of cams configured to rotate between an in-position and an out-position, with said pair of board extractors coupled to said pair of cams;
when said pair of cams are rotated to the out-position a board is dropped from said board magazine to a board staging area adjacent said pair of board extractors, and nail plates are dropped from said pair of nail plate magazines to respective nail plate staging areas adjacent said pair of nail plate extractors; and
when said pair of cams are rotated to the in-position the board is positioned from the board staging area to the board receiving area by said pair of board extractors, and the nail plates are positioned from the nail plate staging areas to the nail plate receiving areas by said pair of nail plate extractors.

5. The nail plater apparatus according to claim 4 , wherein the board in the board staging area is used by said pair of board extractors to push a board out of the board receiving area after the nail plates have been pressed into the board by said pair of nail plate presser assemblies.

6. The nail plater apparatus according to claim 1 , wherein each nail plate presser assembly comprises:
a hydraulic ram;
a press foot coupled to said hydraulic ram; and
a pair of spaced apart nail plate retainer jaws pivotly coupled to said press foot and configured to hold the nail plate when positioned in the nail plate receiving area.

7. The nail plater apparatus according to claim 6 , wherein said pair of nail plate retainer jaws pivotly move to release the nail plate when said hydraulic ram causes the nail plate to be pressed into the board.

8. The nail plater apparatus according to claim 1 , further comprising:
an accumulator apron to receive the boards after the nail plates have been pressed therein by said pair of nail plate presser assemblies; and
a pair of accumulator push arms adjacent said accumulator apron and configured to push the boards after a predetermined number of boards have been stacked on said accumulator apron.

9. The nail plater apparatus according to claim 1 , further comprising a hydraulic cylinder coupled to said pair of nail plate presser assemblies for control thereof.

10. The nail plater apparatus according to claim 1 , further comprising a pneumatic cylinder coupled to said board feeder for control thereof.

11. A method for pressing nail plates into a board comprising:
stacking a plurality of nail plates in a pair of nail plate magazines;
operating a pair of nail plate extractor assemblies associated with a pair of nail plate magazines to position the nail plates therefrom to respective nail plate pressing areas;
operating a board feeder to position a board from a board magazine to a board receiving area; and
operating a pair of nail plate presser assemblies adjacent the board receiving area and aligned with the respective nail plate pressing areas to press the nail plate plates into the board.

12. The method according to claim 11 , wherein the boards feeder and the pair of nail plate extractor assemblies are linked together so that the board is positioned in the board receiving area simultaneously when the nail plates are positioned in the respective nail plate pressing areas.

13. The method according to claim 11 , wherein the board feeder comprises a pair of board extractors, and wherein the pair of nail plate extractor assemblies comprises a pair of nail plate extractors.

14. The method according to claim 13 , wherein a nail plate apparatus further comprises a pair of cams configured to rotate between an in-position and an out-position, with the pair of board extractors coupled to the pair of cams, the method further comprising:
when the pair of cams are rotated to the out-position, a board is dropped from the board magazine to a board staging area adjacent the pair of board extractors, and nail plates are dropped from the pair of nail plate magazines to nail plate staging areas adjacent the pair of nail plate extractors; and
when the pair of cams are rotated to the in-position, the board is positioned from the board staging area to the board receiving area by the pair of board extractors, and the nail plates are positioned from the nail plate staging areas to nail plate receiving areas by the pair of nail plate extractors.

15. The method according to claim 14 , wherein the board in the board staging area is used by the pair of board extractors to push a board out of the board receiving area after the nail plates have been pressed into the board by the pair of nail plate presser assemblies.

16. The method according to claim 11 , wherein each nail plate presser assembly comprises a hydraulic ram, a press foot coupled to the hydraulic ram, and a pair of spaced apart nail plate retainer jaws pivotly coupled to the press foot and configured to hold the nail plates when positioned in the nail plate receiving area, the method further comprising:
pivotly moving the respective pairs of nail plate retainer jaws to release the nail plates when the hydraulic ram cause the nail plate to be pressed into the board.

17. The method according to claim 11 , wherein a nail plate apparatus further comprises an accumulator apron to receive the boards after the nail plates have been pressed into the board by the pair of nail plate presser assemblies, and at least one accumulator push arm adjacent the accumulator apron, the method further comprising:
operating the at least one accumulator push arm to push the boards after a predetermined number of boards have been stacked on the accumulator apron.
