BARS-4 is a new development of the company. The machine is designated for cutting round logs into high-quality edged lumber. The productivity of BARS-4 is two times higher than that of any other BARS machine.
SCOPE OF APPLICATION
The machine is to be used at woodworking factories to manufacture high-quality lumber, glued beam, edge-glued panel, and window, parquet, molding and furniture workpieces.
UNIQUE FEATURES
- High productivity and minimum labor costs
The influence of the human factor on the process of cutting is reduced, consequently the machine productivity is increased and labour costs are reduced.
- Automatic cutting process
The process of cutting is fully automatic thanks to cutting optimization system and automatic lumber removal system
BRIEF DESCRIPTION
The sawlog is secured on a stationery stand of the machine, and a bridge carrying the saw assembly moves along the machine's guide rails.
The process of cutting is accomplished with the help of two pairs of circular saw blades in the vertical and horizontal planes.
Circular saw blades are positioned to a specified size under the control of a microprocessor-based control system, according to the cutting chart tailored by the optimization program in the automatic mode.
The log is clamped and aligned with the help of hydraulic system.
Sawn-off boards are removed automatically by the reverse movement of the bridge at maximum speed to the conveyor. After the board is removed, the saw blades are automatically repositioned and another cut is made.
BARS-4 is complete with
- Conveyors for side slabs
- OPTIMA + MONITORING software
- Bridge remote control (option)
PRINCIPAL BENEFITS
- Two pairs of circular saw blades contribute to the increase of productivity two times compared to other BARS machines
- Automatic process of cutting – only one operator is required
- The machine replaces several machines so the required floor area is significantly reduced as well as the number of workers, and power expenditures
- BARS-4 is compatible with industrial lines due to small size
- The machine is equipped with side slab conveyors and can cut automatically without stops.
- The MONITORING system provides 100% automatic recordkeeping of lumber and raw material and 100% automatic monitoring of machine operation and personnel performance.
- The OPTIMA system provides the variability of cutting and contributes to the minimization of wood waste.
The program allows to obtain
- high lumber yields of 63-69%
- maximum yield of quarter-sawn lumber (up to 90% of the total lumber)
