    • 专利摘要:
    An elongated workpiece having unfinished side surfaces inclined laterally downwardly and outwardly from a finished top surface is scanned to produce signals denoting location of the longitudinal edges of the top surface at numerous points along them. An elongated scanning zone, extending across the workpiece, is translated all along the workpiece. In synchronism with scanning zone translation the workpiece is alternately illuminated from opposite sides at a low angle of incidence to the top surface to shadow first one side surface, than the other. Scanning lengthwise along the scanning zone is synchronized with translation of that zone and lighting alternation.

    reflector 3 around the horizontal axis, computational b, one input of which is connected with the output of recorder 2, and the second with the output of block 7 for synchronizing the beam illumination and rotation of the reflector, means of fixed installation of the bar and orientation perpendicular to the longitudinal axis, made in the form support rollers 8 and control tapes 9, 10, recording unit L, the input of which is connected with the output of computing unit 6 ..
    The operation of the device is as follows.
    To determine the size of the board, the location of the edges 12, 13 and to determine the dawn location of the beam 14 in the woodworking machine and the position of the saws 15, 16 when trimming the edges so that the waste is minimal, the beam 14 is installed on the rollers 8 and tape 9, 10 and illuminated by sources 1. Light sources are located in two rows, on both sides of the beam and at an angle to its upper surface, which, when switched on alternately, of the sources, the upper surface of the beam obscures the edges 12, 13 located at an obtuse angle to this surface. awes This achieves such a dramatic separation of the lines delimiting the upper surface of the beam 14 and its edges 12, 13, that this line is clearly detected with the help of a signal generated by the photoelectric recorder 2. The photoelectric recorder 2 outputs signals to the computing unit 6 associated with an actuator (not shown), controls the ribbons 9, 10 and adjusts the distance between the saws 15, 16, which can vary according to the width of the boards. The control of switching on the light sources 1 is carried out using block 7. synchronization, which is associated with the computing unit and the light source switching switch :. A pulse generator 5 coupled to the computing unit 6 coupled to the reflector 3 generates a periodic signal used. First, to synchronize the light sources during board processing and secondly to indicate the location of the points to be examined along the length of the beam, in other words to create a coordinate axis with which the corresponding. It carries a photoelectric recorder 2 signal.
    Thus, introducing into the design of the device the scanning reflector of the block for lighting the beam and turning the reflector, as well as the means for installing and orienting the beam, made it possible to get clear signals with high accuracy indicating the location of the demarcation lines in each of the row of points without moving the beam, and .also provide significant savings in consumable material.
