Abstract
The present invention discloses a log sawing system comprising multiple cutting blades. The multiple cutting blades are positioned to cut laterally or perpendicular to the centerline of the log which is to be cut. The logs are transported into cutting position using some type of log positioner. The multiple cutting blades are rotatably mounted on an arm which is pivotally mounted on a shaft in groups, being driven by an electrical or like motor, all of which are mounted onto a platform positioned adjacent to the log to be cut. Hydraulic lifters are used to partially rotate the saw blades into the cutting position adjacent the log. Means utilizing a computer and lasers are provided to develop a log cutting solution to best utilize the logs.
Claims12
An apparatus for cutting logs, comprising:
- a) a plurality of cutting blades, said blades being rotatable;
- b) a frame for supporting said plurality of cutting blades;
- c) a means for conveying the logs to said plurality of cutting blades;
- d) a means for conveying the logs away from said plurality of cutting blades;
- e) a plurality of arms having one each of said cutting blades disposed thereon;
- f) means for moving said plurality of arms between an upward position or a downward position;
- g) means for rotatably mounting said cutting blades on said arm;
- and
- h) at least one drive shaft for rotatably driving said plurality of cutting blades in both of said upward and downward positions, such that at least one of said rotating blades may be moved by said arm to the downward position and continue rotating so as to cut the logs while the remaining of said cutting blades continue rotating in said upward position.
