Abstract

Various embodiments of the present disclosure provide a lumber handling and cutting apparatus, including an incoming material conveyor assembly, a material infeed assembly adjacent to the incoming material conveyor assembly, a cutting assembly adjacent to the material infeed assembly, a material outfeed assembly adjacent to the cutting assembly, an outgoing material conveyor assembly adjacent to the cutting assembly, and a printer assembly adjacent to the incoming material conveyor assembly and the material infeed assembly.

First claim

The claims are as follows:

1. A lumber handling and cutting apparatus comprising:
an incoming material conveyor assembly;
a material infeed assembly adjacent to the incoming material conveyor assembly;
a cutting assembly adjacent to the material infeed assembly; and
a printer assembly adjacent to the incoming material conveyor assembly, the printer assembly comprising:
a printer support base;
a printer support frame supported by and connected to the printer support base;
a printer support arm supported by and connected to the printer support frame;
a print head mounting bracket connected to the printer support arm;
a print head supported by and connected to the print head mounting bracket, the print head configured to print on a lumber board as the lumber board passes the print head;
a multi-size board alignment assembly at an end of the incoming material conveyor assembly adjacent to the material infeed assembly, wherein the multi-size board alignment assembly is configured to align the lumber board with respect to the print head prior to the print head printing on the lumber board; and
a print sensor configured to detect the lumber board and to cause activation of the print head,

wherein the incoming material conveyor assembly is configured to, after the lumber board is aligned with the print head, back the lumber board up before feeding the lumber board to the material infeed assembly, and
wherein the multi-size board alignment assembly is configured to, at a point the lumber board is over halfway underneath the print head and a lumber board center of gravity passes over a center of the multi-size board alignment assembly, allow the lumber board to feed downwardly into the material infeed assembly.

2. The lumber handling and cutting apparatus of claim 1 , wherein the print head is positioned facing downwardly.

3. The lumber handling and cutting apparatus of claim 1 , wherein the print head is positioned at a transition point between the incoming material conveyor assembly and an infeed conveyor of the material infeed assembly.

4. The lumber handling and cutting apparatus of claim 3 , wherein the printer support frame is configured such that the printer support arm is above the transition point.

5. The lumber handling and cutting apparatus of claim 1 , wherein the print head mounting bracket is attached to the printer support arm such that the print head is positioned above a transition point between the incoming material conveyor assembly and an infeed conveyor of the material infeed assembly.

6. The lumber handling and cutting apparatus of claim 1 , wherein the multi-size board alignment assembly is connected to feed members of the incoming material conveyor assembly.

7. The lumber handling and cutting apparatus of claim 6 , wherein the multi-size board alignment assembly includes an idler roller positioned at an end of one of the feed members of the incoming material conveyor assembly.

8. The lumber handling and cutting apparatus of claim 6 , wherein the multi-size board alignment assembly is positioned at a transition point between the feed members of the incoming material conveyor assembly and the infeed conveyor of the material infeed assembly.

9. The lumber handling and cutting apparatus of claim 1 , wherein the multi-size board alignment assembly is configured to align the lumber board with respect to the print head for a period of time as the lumber board passes underneath the print head.

10. The lumber handling and cutting apparatus of claim 9 , wherein the incoming material conveyor assembly is configured to deliver the lumber board such that the lumber board can be aligned under the print head prior to passing underneath the print head for the period of time.

11. The lumber handling and cutting apparatus of claim 1 , wherein the multi-size board alignment assembly is attached to the material infeed assembly.

12. A lumber handling and cutting apparatus comprising:
an incoming material conveyor assembly;
a material infeed assembly adjacent to the incoming material conveyor assembly;
a cutting assembly adjacent to the material infeed assembly; and
a printer assembly adjacent to the incoming material conveyor assembly, the printer assembly comprising:
a print head;
a multi-size board alignment assembly at an end of the incoming material conveyor assembly adjacent to the material infeed assembly, wherein the multi-size board alignment assembly is configured to align a plurality of different lumber boards of different dimensions with respect to the print head prior to the print head printing on each of the plurality of different lumber boards without adjusting a position of the print head and without reconfiguring the print head; and
a print sensor configured to detect the lumber board and to cause activation of the print head,
wherein the incoming material conveyor assembly is configured to, after each of the lumber boards is aligned, back each lumber board up before feeding each lumber board to the material infeed assembly, and
wherein the multi-size board alignment assembly is configured to, for each of the plurality of different lumber boards, at a point that said lumber board is over halfway underneath the print head and a lumber board center of gravity of said lumber board passes over a center of the multi-size board alignment assembly, allow said lumber board to feed downwardly into the material infeed assembly.
