Abstract

A nail plater apparatus includes a board magazine configured to hold stacked boards, and a pair of spaced apart nail plate magazines, with each nail plate magazine configured to hold stacked nail plates. The nail plater apparatus includes a pair of spaced apart nail plate extractor assemblies, with each nail plate extractor assembly associated with a respective nail plate magazine and configured to position a nail plate therefrom to a respective nail plate pressing area. A board feeder is configured to position a board from the board magazine to a board receiving area, with ends of the board being aligned with the nail plates positioned in the respective nail plate pressing areas. A pair of spaced apart nail plate presser assemblies overlie ends of the board receiving area and is aligned with the respective nail plate pressing areas to press the nail plates into the ends of the board.

First claim

That which is claimed:

1. A nail plater apparatus comprising:
a board magazine configured to hold a plurality of stacked boards;
a pair of spaced apart nail plate magazines, with each nail plate magazine configured to hold a plurality of stacked nail plates;
a pair of spaced apart nail plate extractor assemblies, with each nail plate extractor assembly associated with a respective nail plate magazine and configured to position a nail plate therefrom to a respective nail plate pressing area;
a board feeder configured to position a board from said board magazine to a board receiving area, with ends of the board being aligned with the nail plates positioned in the respective nail plate pressing areas; and
a pair of spaced apart nail plate presser assemblies overlying ends of the board receiving area and aligned with the respective nail plate pressing areas and configured to press the nail plates into the ends of the board.

2. The nail plater apparatus according to claim 1 , wherein said board feeder and said pair of spaced apart 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 , wherein said board feeder comprises a pair of spaced apart first and second board extractors, and wherein said pair of spaced apart nail plate extractor assemblies comprises a pair of spaced apart first and second nail plate extractors.

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

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

11. A nail plater apparatus comprising:
a board magazine configured to hold a
plurality of stacked boards;
a pair of spaced apart nail plate magazines, with each nail plate magazine configured to hold a plurality of stacked nail plates;
a pair of spaced apart nail plate extractor assemblies, with each nail plate extractor assembly associated with a respective nail plate magazine and configured to position a nail plate therefrom to a respective nail plate pressing area;
a board feeder configured to position a board from said board magazine to a board receiving area, with ends of the board being aligned with the nail plates positioned in the respective nail plate pressing areas;
a pair of spaced apart nail plate presser assemblies overlying ends of the board receiving area and aligned with the respective nail plate pressing areas and configured to press the nail plates into the ends of the board;
said board feeder and said pair of spaced apart nail plate extractor assemblies being 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;
an accumulator apron to receive the boards after the nail plates have been pressed into the ends thereof by said nail plate presser assemblies; and
at least one accumulator push arm adjacent said accumulator apron configured to push the boards after a predetermined number of boards have been stacked on said accumulator apron.

12. The nail plater apparatus according to claim 11 , wherein said board feeder comprises a pair of spaced apart first and second board extractors, and wherein said pair of spaced apart nail plate extractor assemblies comprises a pair of spaced apart first and second nail plate extractors.

13. The nail plater apparatus according to claim 12 , further comprising:
a pair of spaced apart first and second cams each configured to rotate between an in-position and an out-position, with said first board extractor coupled to said first cam and said second board extractor coupled to said second cam;
a first linkage coupled between said first cam and said second nail plate extractor, and a second linkage coupled between said second cam and said first nail plate extractor;
when said first and second cams are rotated to the out-position a board is dropped from said board magazine to a board staging area adjacent said pair of spaced apart first and second board extractors, and nail plates are dropped from said pair of a nail plate magazines to a nail plate staging area adjacent said pair of spaced apart first and second nail plate extractors; and
when said first and second 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 spaced apart first and second board extractors, and the nail plates are positioned from the nail plate staging areas to the nail plate receiving areas by said pair of spaced apart first and second nail plate extractors.

14. The nail plater apparatus according to claim 13 , wherein the board in the board staging area is used by said first and second board extractors to push a board out of the board receiving area after the nail plates have been pressed into the ends thereof by sa
