Patent number: 4977805Abstract: An edging apparatus edges a wood board to achieve a desired rounding effect under a rounding rule of the lumber industry. A positioning apparatus positions and holds two edging saws, and the positions of the saws are initially controlled by an operator who selects initial cut positions. Input data, including board length and thickness parameters and the initial cut positions are generated by input devices and a computer is responsive to the input data for computing the best cut positions of the saws. In making this computation, the computer takes into consideration the rounding rule and, according to predetermined criteria, the computer selects best cut positions that will produce an edged board whose measurement exceeds a whole board foot measurement by a desired fraction of a board foot. Adjustment input may be provided to adjust the size of the desired fraction of the board foot.Type: GrantFiled: June 16, 1987Date of Patent: December 18, 1990Assignee: Corley Manufacturing CompanyInventor: Andrew J. Corley, III

Patent number: 4972743Abstract: An apparatus for feeding sheets comprises a variable speed conveyor for feeding a sheet cut from a web. A high speed conveyor receives the sheet fed by the variable speed conveyor, and feeds it at a high speed v1. A cutting completion detector detects the separation of the sheet from a cutter and generates a detection signal. A controller adjusts the feeding speed of the variable speed conveyor to a feed speed v2 as long as the leading portion of the web is being fed to the cutter, adjusts the feeding speed to a speed v0 (v0<v1, v2), at which the sheet is kept stationary with respect to the cutter, during the time from when the cutter starts cutting the web to when the cutting is finished and the cut sheet separates from the cutter, and increases the feeding speed from the speed v0 to the speed v1 during the time from when the detection signal is generated to when the sheet arrives at the high speed conveyor.Type: GrantFiled: May 16, 1989Date of Patent: November 27, 1990Assignee: Fuji Photo Film Co., Ltd.Inventor: Yoshio Nojima

Patent number: 4951215Abstract: A lineal output measurement circuit adapted for use with product cutting apparatus, primarily with wood cutting apparatus of the type which have a plurality of simultaneously operable cutting elements. This product cutting apparatus is thereby capable of cutting product stock, such as ripping of a wood member simultaneously into individual wood section strips with a plurality of saw blades positioned to cut the individual strips. The apparatus generally includes some form of input mechanism for programming the cutting mechanism to produce the individual sections of product, that is, to produce the desired amount of the selected widths of product. The measurement circuit of the present invention utilizes program electrical signals from the apparatus which provide a program input representative of the different sizes of product sections to be produced, along with a port circuit and a processing means.Type: GrantFiled: February 21, 1989Date of Patent: August 21, 1990Assignee: Sanford-Lussieng, Inc.Inventor: Paul K. Scherer

Patent number: 4947909Abstract: A system of optimizing the volume of boards that may be cut from a log provides for one surface of a cant to be cut with a curved or straight surface. This takes into account curved, tapered or straight logs. The system comprises a scanner positioned to scan the log and determine an optimum cut surface profile, a cutting head positioned to cut the top surface of the log, the cutting head having relative vertical movement to the top surface, a conveyor to convey the log passed the scanner and the cutting head, and a controller to control the relative movement of the cutting head in accordance with the signal from the scanner to produce the predetermined optimum cut surface profile for the top surface of the log.Type: GrantFiled: February 14, 1989Date of Patent: August 14, 1990Assignee: CAE Machinery Ltd.Inventor: Brian T. Stroud

Patent number: 4941100Abstract: A controller for a head rig edger saw for sawing the edges of a board that is cut from a log by a head saw includes a detector for determining the surface contour of the log to be sawed, along a line displaced from the face of the log; a computer device for selecting an edger saw line through the log from the surface contour to produce a board satisfying predetermined criteria; and an edger saw controller connected to the computing device for providing control signals to the edger for causing the saw to cut the board along the selected line.Type: GrantFiled: November 30, 1988Date of Patent: July 10, 1990Inventors: Arthur M. G. McFarlane, Stuart R. McFarlane

Patent number: 4926917Abstract: A feed speed control for band saws avoids overfeeding and underfeeding of logs or cants to allow higher initial input feeds and takes into account varying cutting depth throughout a log or cant length. The method comprises the steps of positioning a log or cant in preparation for sawing in a saw line, projecting a first light line onto the surface of the log or cant at the projected saw entry line, and a second light line onto the surface of the log or cant at the projected saw exit line and the second light line to determine depth of cut, and controlling the feed speed of the log or cant during the sawing step past the saw blade, to a predetermined feed speed for the measured depth of cut to avoid overfeeding and underfeeding.Type: GrantFiled: July 10, 1989Date of Patent: May 22, 1990Inventor: Eberhard Kirbach
