Abstract
A high-throughput, high-end-product-recovery, lineal log bucking device featuring continuous stem travel during the cutting process by using a simple and efficient machinery design for economy of equipment and monies. The apparatus includes: (1) a saw for cutting stem into logs; and (2) apparatus for accelerating the carrier up to the speed of the stem conveyor(s), maintaining the speed during the cut, decelerating the carrier, and then returning the carrier to its starting point.
Claims9
A saw system for cutting a stem continuously moving lengthwise along a lineal conveyor, said saw system comprising:
- a. saw carrier means comprising a support frame movably supported on at least two lineal tracks each aligned at least obliquely above a different longitudinal side of a lineal conveyor path and each supporting an upper crier frame having a lower carrier frame downstanding therefrom, said upper carrier frames including roller means for riding along said lineal tracks, said lower carrier frames including means for pivotally supporting a cutting lever arm obliquely above the lineal conveyor path;
- b. at least two independent saw means each comprising said cutting leverage arm having an upper lever end, a lower cutting end, and said pivotal supports fulcrumatic therebetween and obliquely above a different longitudinal side of the lineal conveyor path, said lower cutting end including a saw, said upper lever end connected to one end of means, attached to said carrier frames for urging said saws essentially pendularly through the stem;
- and
- c. control means synchronizing a positioning of said saws with the travel of the stem so that said saw will be positioned to cut the stem at a desired variable cut point without stopping stem travel.
