Method and Device for Automatic Packing of Wood

A method of preparing wood for packing comprises: loading wood lengthwise into a conveyor system; conveying the wood pieces one-by-one onto a loading hatch in a predetermined orientation; when a wood piece is fully on the loading hatch, opening the loading hatch and dropping the wood piece in the predetermined orientation into a measuring compartment; repeating the conveying and dropping process so that multiple wood pieces are stacked in the same orientation in the measuring compartment; and, when a required amount of stacked wood is within the measuring compartment, dropping the stacked wood pieces into a packing area.

Automated Compound Retrieval and Delivery of Lumber
20170217022 · 2017-08-03 ·

An automated lumber handling method for transferring various size boards from multiples board storage stations to a common board-receiving area uses a trolley that carries at least two board pickers that can operate independently. The method provides several operating modes. In a first mode, a first board picker retrieves single boards from various stations, while a second board picker is inactive. In a second mode, two board pickers retrieve two individual boards from a single station. In a third mode, one board picker retrieves one size board from a first station, and s second board picker retrieves a different size board from a second station. The two different boards can be released simultaneously at the board-receiving area. In some examples, the lumber at each station is laser scanned to determine the number of boards at each station, and a worker is notified if a station needs to be restocked.

Process accuracy and throughput in a system for processing timber and lumber with a circular gang saw can be improved by measuring a sawing force and a guide friction force near an end of one or more saw arbors and incorporating the force measurement into a process control system to adjust the workpiece feed speed (or other process parameters) to achieve better results.

Adjustable positioning structure for feeding support plate of circular sawing machine

An adjustable positioning structure for a feeding support plate of a circular sawing machine contains a magnetic element, a micro pneumatic cylinder, and a control button. The magnetic element is accommodated in a magnetic slider which is fitted with a guide column on a material feeding side of a table of the circular sawing machine and is configured to produce a change of a magnet value of the magnetic slider when the magnetic slider moves along the guide column reciprocately, such that a displacement value of the magnetic slider is calculated and is displayed by a display on the magnetic slider. The micro pneumatic cylinder is mounted on the magnetic slider and is configured to fix or release the magnetic slider relative to the guide column. The control button is arranged on the feeding support plate and is configured to control the micro pneumatic cylinder to operate.

Pass-under lumber transfer methods and systems

A lumber transfer system includes an overhead track and a lower conveyor for retrieving and delivering boards from multiple racks of lumber to a platform leading to a saw. In some examples of operation, a board picker travels along the track to pick up a chosen board from one of the racks. The board picker then releases the board onto the conveyor. The conveyor conveys the board underneath the other racks and delivers the board to the saw feed platform. While the conveyor is conveying the board toward the saw feed platform, the board picker returns to the racks for another board. The board picker traveling along the track and handling boards while the conveyor delivers them to the saw saves production time and increases throughput.

LOG AND CANT OPTIMIZATION

Embodiments provide methods, apparatuses, and systems for cutting wood workpieces, such as logs and cants, into desired products. In various embodiments, after a log is chipped into a cant, the cant may be scanned and re-optimized based on the new scan data and information about the source log, such as simulated orientation parameters, a 3D model, and/or potential cut solutions. In other embodiments, data from multiple sensor types may be used in combination to detect splits in logs, cants, or both. Optionally, re-optimization and split detection techniques may be used in combination to improve wood volume recovery, value, and/or throughput speed.
