  • Publication number: 20130334346
    Abstract: A wood chipper comprises a frame, an infeed system, a rotatable cutting system, and at least one feed wheel disposed between the infeed system and the cutting system to feed wood material to the cutting system. The wood chipper also includes a winch comprising a winch line having a first end, and a collar disposed adjacent the first end of the winch line. The wood chipper further includes a detector adapted to detect a first and a second position of the winch line, wherein the detector is adapted to allow operation of the at least one feed wheel and prohibit operation of the winch when the first position of the winch line is detected, and to allow operation of the winch and allow operation of the at least one feed wheel in a predefined manner when the second position is detected. The wood chipper further comprises a bypass for operation of the at least one feed wheel.

  • Patent number: 7974731
    Abstract: The disclosure relates to a computer-implemented method for stacking wood products. In some embodiments, the disclosure the steps of designing at least two types of engineered wood products via a software application; producing the at least two types of engineered wood products based on the designs utilizing a saw in conjunction with the software application; designating, via the software application, at least two bins to hold the at least two different types of engineered wood products; selecting a first bin for depositing a first type of engineered wood product; selecting a second bin for depositing a second type of engineered wood product; automatically placing the first type of engineered wood product into the first bin; and automatically placing the second type of engineered wood product into the second bin. The at least two types of engineered wood products are at least two of: panels, I-joists, headers and dimensional lumber.

  • Patent number: 7801637
    Abstract: Provided is a system for cutting and sorting of engineered wood products. Using appropriate software, a designer may model an entire house's structural frame. The dimensions and labeling for individual members of the structure are extracted from the model and captured by the software. The software may batch and optimize the products to be cut on the saw and develop sawing control instructions. The instructions are used by the saw to process the parts according to the house structure design. As the parts are processed by the saw, they are discharged and sent to an outfeed system that will stack the engineered wood products according to the parameters defined by the workstation operator. The system can handle the multiple lengths and widths of engineered wood parts from the saw and stack them in the order the software may specify.

  • Patent number: 6651798
    Abstract: An apparatus for repositioning a workpiece on a lugged conveyor, where the conveyor has lugs for carrying the workpiece spaced apart by a lug space in a downstream direction. The apparatus includes a sensor for detecting the position of the workpiece on the conveyor and relaying position information to a processor, at least one running element mountable in cooperation with the conveyor, a selectively actuable actuator cooperating with the processor for the selective actuation of the running element.

  • Patent number: 6561238
    Abstract: A door preparation station includes a data processing control system that drives a display for presenting sequential series of menu selections that illicit operator information that is used as control data to configure the station for preparing a door for receipt of predetermined door hardware (e.g., locks, hinges, etc.) of one type or another. Based upon responses received at the menu selections, the processing system positions and operates various door preparation cutting and drilling elements for the door preparation procedure.

  • Patent number: 5564483
    Abstract: A machining unit, typically for wood panels, features a work table afforded by a body of prismatic geometry having at least two faces and rotatable about an axis which is also its instantaneous center, in such a way as to establish at least two movable and tiltable work surfaces; the prismatic body is carried within a frame encompassing the tool and combining with the two faces to create respective independent work areas, one in which panels are fed to and from the unit, the other coinciding with a station at which machining takes place, and where the waste and chips generated by machining are cleared from the table and the work. The prismatic body also functions as the main barrier separating two work environments, the one an open external space occupied by the operator, the other an enclosure disallowing access to the operator while machining is in progress.
