209517000 | Sorting lumber, logs, pipes, rails, or like items | 7 |
20080197054 | Means and Method for Classifying Logs - A mechanism ( | 08-21-2008 |
20080237096 | Methods for determining pith direction and location in lumber - Methods are provided for determining a location of a pith along a length of a wood sample. The methods may comprise the steps of: determining pith direction; selecting two areas of the wood sample at which two or more chords of a ring can be defined; bisecting the chords to define a line perpendicular to the chords; and locating at least one intersection point for two or more of the bisecting perpendicular lines. | 10-02-2008 |
20100116721 | Wig wag bin flow directors - The flow director apparatus according to the present invention in such bins include a plurality of the flow directors which are pivotally mounted or mountable beneath said plurality of diverter gates and to said upper end of said frame so as to depend a free end of each flow director of said plurality of said flow directors downwardly from said upper end into an entrance cavity of said bin defined by said upper end of said frame. Each flow director is elongate and has a base end opposite said free end. Each flow director pivotally is mounted or mountable to said upper end of said frame at said base end of the flow director. | 05-13-2010 |
20130233774 | APPARATUS AND SYSTEM OF A SORTER AND METHOD FOR SORTING WOOD PIECES - The present disclosure relates to a system and method of a sorter and a method for sorting wood pieces and for guiding them to a conveyor. This type of sorter comprises a lower frame, a receiving deck for wood pieces, and a feeder for detaching a wood piece from the receiving deck. Said feeder comprises a controller for supporting the wood piece during movement directed to it and transferring it substantially vertically from the receiving deck. In that case the control means is traversed by at least two bearers controlled by an actuator for producing the vertical movement of the wood piece. The bearers are arranged to project from an outer surface of the controller by an amount of projection that is adjustable during lifting. The feeder further comprises a measuring unit for detecting a wood piece of a given diameter (e.g., the largest or larger cross-sectional diameter) on the bearers and for controlling the projection of the bearers to a position corresponding to this given diameter. | 09-12-2013 |

20080223767 | Selection and bundling apparatus for random length materials - An apparatus for selecting and sorting a plurality of random length boards to form at least one row of boards having a total length within a predetermined target length range includes a measurement section operative to measure the length of each board and a sorting section which includes a sorting device and system for sorting the boards. An accumulating row section accumulates and stores rows of boards selected from the plurality of boards and a vacuum suction transport device moves rows of boards from the accumulating rows to a bundling section which receives rows of boards and then bunches and aligns the rows of boards and bundles the rows of boards in a board row bundle. Finally, a central processor performs all calculations and controls to properly sort the boards to create bundles of rows of boards having a total length generally within a predetermined target length range. | 09-18-2008 |
20080223768 | Vacuum suction transport carriage for a selection and bundling apparatus for random length materials - A vacuum suction transport carriage includes a movably mounted carriage body, a vacuum suction generating device and a vacuum picker apparatus mounted on the carriage body, the vacuum picker apparatus including a main frame and at least two vacuum bar assemblies mounted on the main frame. These each include extension and retraction devices mounted on and extending downwards from the main frame and a vacuum bar mounted on a lower end of the extension and retraction device, the vacuum bar including a plurality of suction pads connected to the vacuum suction generating device. At least one of the at least two vacuum bar assemblies is transversely movably mounted on the main frame to alternatively increase and decrease the transverse distance therebetween to engage boards with the suction pads having suction applied thereto via the vacuum suction generating device for transport thereby, lift the boards via retraction of the extension and retraction device, and move the boards into adjacent proximity via transverse movement of the vacuum bar assemblies for transport of the boards. | 09-18-2008 |
20090184033 | Wood products having warp orientation indicia and methods for making the same - The method is provided that identifies warp orientation of a wood product in an automated or semi-automated process, and affixes the wood product with indicia that will assist the end user, such as a framing carpenter, a finish carpenter, a trim carpenter, etc., with improved wood product application, e.g., studs, beams, joists, molding, etc, and in-service placement. e.g., location and orientation. Wood products with warp orientation indicia are also provided. | 07-23-2009 |
