Abstract
A sawmill for tree logs includes a rocking carriage to pick up fresh logs and feed them into the path of a saw blade, as well further provisions relating to improvements to infeed systems for the fresh logs, as well as to, outflow systems for transfer of sawn-off product to a production line conveyor or the like for further processing to downline processes after the first saw cuts on the fresh logs.
Claims7
A sawmill for logs comprising:
- a bandsaw mounted on a carriage for traversing between left and right extremes;
- a rocking carriage supporting and manipulating a log loaded into the rocking carriage at an elevation above a ground plane during saw operations;
- an infeed log deck rearward of the rocking carriage comprising a conveyor supporting a multiplicity of fresh new logs and serially forwarding for the loading of one fresh new log at a time from the multiplicity of logs into the rocking carriage;
- an outflow downslide for catching fresh sawn off slices or planks sawn free from the log loaded into the rocking carriage during saw operations;
- said racking carriage comprising a log bunk comprising a spaced plurality of frames collectively defining a plane of the log bunk which primarily serves as a support deck for the log loaded into the rocking carriage during saw operation and secondarily serves as a backstop surface for the fresh new log during fresh new log loading operations;
- said rocking carriage further comprising plural head assemblies coupled with respect to the log bunk to translate over the plane of the log bunk between forward and rearward extremes;
- each head assembly presenting a forward-facing surface that can be individually adjusted to be collectively contained in a plane of the forward-facing surfaces that is generally perpendicular to the plane of the log bunk;
- said rocking carriage being arranged to rock forwardly and rearwardly between clockwise and counterclockwise extremes about a rocking axis;
- wherein the plane of the log bunk and the plane of the collective forward-facing surfaces of the head assemblies define essentially a perpendicular vertex;
- wherein the bandsaw comprises a saw blade which makes saw cuts in a given plane of saw blade cutting travel;
- and
- wherein the bandsaw is carried by the carriage therefor such that the given plane of saw blade cutting travel is tilted rearwardly to such an angle from vertical that each fresh sawn off slice or plank sawn free from the log loaded into the rocking carriage during saw operations has a fresh sawn face that lands down on the outflow downslide.
