Technical update: sawmill scanners and optimizers in 2021


Automatic recording
Autolog launches a revolutionary new sensor called R-TRAC Rotation Tracking. This new sensor takes live measurements while the log is rotating. It is a fully autonomous system, independent of the geometric model of the log optimizer and works with all types of log turners, regardless of the brand of optimizer installed. No mechanical modification is required on the log turner or on the feed chain. Integration with any control system (PLC) is very easy, as R-TRAC allows the use of closed loop feedback to control the position of the log turner cylinders based on rotation instead of their linear motion. The R-TRAC system maintains a continuous reading of the rotation angle while the log is in the field of view instead of applying a rotation correction after the rotation is complete. R-TRAC has an accuracy better than five degrees of standard deviation using all data.

JoeScan’s newest sawmill scanner is quickly becoming a scanner of choice for optimization integrators across North America. Hundreds of JS-50 sweepers are currently operating in a wide variety of sawmill systems, including log merchandising / chopping, whole log decomposition, groups, edger and trimmer. The JS-50 family of scanners has several innovative features to improve reliability and usability, such as a single-cable Power over Ethernet (PoE) connector, which reduces the number of cables, Picatinny-inspired QuikMount which enables installations faster and secure fixation, and next-generation image sensors that provide high-resolution gray scale for flaw detection.

IDB Group
BID Group has developed a complete suite of SmartTools to improve and ensure constant optimization performance. These software applications monitor equipment, analyze performance and optimization, identify errors in real time, make adjustments, run diagnostics on automation equipment, and more. SmartTools allow operators to intervene quickly before errors or defects affect quality or operations. For example, the Primary Breakdown SmartTool secures the optimal cant position. It also uses the data from the scanner (which provides the real and complete form of the log) for the closed loop system which ensures maximum optimization of the log.

Automated quality control systems have been available for years from third parties, but closing the loop completely requires original optimization data. USNR’s Self-Adjusting Machine (SAM) technology digitizes each part before and after each cutter. Prior scanning allows the optimizer to develop a fault solution. Scanning subsequently identifies how the part was actually cut. Using the trends in the data from this second scan, SAM transmits the corrections to the PLC. If the workpiece is not the correct size, it is important to know which saw is not in position, as well as how much and in which direction it needs to be adjusted. SAM technology closes the loop, providing comprehensive data to automatically adjust saws.

Woodtech SA
Logmeter is an automatic scanning system that measures and inspects logs loaded on trailers in real time before entering the plant and provides high precision solid volume measurements and estimates biometric characteristics. These results allow operators to control the quality and real value of the logs purchased, thus improving fair trade. In addition, all information is recorded in its audit system, serving as evidence to improve the procurement process. Logmeter has been present in North America for 10 years. Woodtech is a technology company focused on the design, development and maintenance of innovative high-tech industrial solutions that digitize, interpret and measure industrial processes in real time.

SiCam Systems
For over 30 years, SiCam Systems has been developing and advancing quality control technologies. SiCam’s systems are designed for on-line and off-line product inspection. SiCam’s real-time scanning systems reliably and accurately measure logs, slopes or boards during production. SiCam Realtime will verify that factories are producing what they intended and allow factories to cut closer to target and achieve target size reductions. SiCam’s web interface software will allow operators to visualize what is happening with products and machining centers, allowing them to make machine adjustments when needed. SiCam can also make these adjustments with SiCam’s closed loop size control.

Prological +
Prologic + recently announced a major contract with one of Eastern Canada’s leading lumber manufacturers, Groupe Lebel, for the delivery of the Finnos ProX-Ray log sweeping system next spring. This delivery will mark the opening of North American markets for the Finnos / Prologic + alliance. Finnos ProX-Ray log scanners can be used to detect rot, assess MSR qualities or take into account internal defects such as knots and cracks for internal grades. This scanner can be equipped on log sorters, displays and saw lines.

Raptor integration
The FL5000-S Rod Optimizer is the evolution of Raptor’s log analysis optimization to meet upstream merchant requirements. The system supports single or multiple linear scan areas to create the 3D rod model at high production speeds with 1/2 inch scan resolution between slices. It also has full log optimization for each segment, board deflection setup to match Raptor’s log optimization, route specific logging solutions for preferred downstream machining centers , fixed and / or flying saws with configurable scope constraints and an intuitive results screen with 3D graphics and critical solution information. The web architecture allows users to connect remotely from PCs, tablets or phones.

Airstar manufactures quality control systems for the forest products industry such as plywood, LVL, OSB, glulam, lamination, hardwood floors, MDF, crack detection in solid wood, finger joint and MDF density testing. Airstar’s signal-to-noise ratio is unmatched in the industry. Airstar Blow (Blister) detectors penetrate products up to 10 inches thick and can be configured for full panel testing. The Airstar thickness measurement system uses high resolution laser sensors. Over the past 20 years, Airstar has replaced 61 competitive systems.

Finna sensors
Scanframe enables the OMNIR near infrared layer moisture and weight sensor to take multiple readings on a strip, rather than just measuring a fixed point. Powered by a motor and gear system, Scanframe is a non-contact aluminum beam, with customizable width, that allows operators to position OMNIR to perform manual and pre-programmed readings. To facilitate line integration and data output, Scanframe has its own control panel, intelligent software and a motorized guidance system that accepts motion patterns adaptable to different line speeds.

Accurate log rotation before the first processing step is essential to achieve high value recovery. With its optimization software, Linck uses 3D scan data to generate a value-optimized cutting model, then determines the angle required for the logs to rotate. With Log Motion Control, Linck presents a new stage in the development of this technology. In addition to determining the angle of rotation of the log, a Microtec Truespin scanner will be used when a camera records a characteristic pattern on the surface of the log and the position of the log is transmitted to the Linck Log Motion Control during the entire process. rotation process. The software determines the true rotational position of the log to compare with the theoretical position. Any deviation will be compensated by immediately adjusting the position of the rotating rollers. The ball rotation process is therefore under the full control of the Linck Log Motion Control software.
