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.
Claims22
An apparatus for cutting a log, the apparatus comprising:
- a plurality of rotational drive devices;
- a plurality of drive shafts, each of said drive shafts being operably connected to a respective one of said drive devices;
- and
- a plurality of cutting blades, at least two of said blades being operably connected to each of said drive shafts, each of said cutting blades being moveable between first and second positions such that said cutting blades in the second position are configured to cut the log in a cutting position,
- wherein each cutting blade operably connected to a respective one of said drive shafts is configured to be moved to the second position while at least one of said blades operably connected to the respective drive shaft is in the first position such that the log in the cutting position is cut by less than all of the cutting blades operably connected to each of said drive shafts.
An apparatus for cutting logs, comprising:
- a plurality of cutting blades, said blades being rotatable;
- a frame for supporting said plurality of cutting blades;
- a log positioner for conveying the logs to said plurality of cutting blades;
- a plurality of arms having one each of said cutting blades disposed thereon;
- a plurality of lifters for moving said arms between an upward position and a downward position;
- and
- 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.
