Description
нировани рефлектора 3 вокруг горизонтальной оси, вычислительный б, один вход которого св зан с выходом регистратора 2, а второй с выходом блока 7 синхронизации освещени бруса и поворота рефлектора , средства неподвижной установки .бруса и ориентации его перпендикул рно к продольной оси, выполненные в виде опорных роликов 8 и управл кщих лент 9, 10, регистрирующий блок Л, вход которого св зан с выходом вычислительного блока 6..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 ..
Работа устройства заключаетс в следующем.The operation of the device is as follows.
Дл определени размеров доски, местоположени кромок 12, 13 и дл рассветного определени места установки бруса 14 в деревообрабатывающем станке и положени пил 15, 16 при обрезке кромок, чтобы отходы были минимальными, брус 14 устанавливаетс на ролики 8 и ленты 9, 10 и освещаетс источниками света 1. Источники света располагаютс при этом в два р да, по обе стороны от бруса и под углом к .его верхней поверхности , что при поочередном включении , источников верхн поверхность бруса затен ет кромки 12, 13, расположенные под тупым углом к этой поверхности. Этим достигаетс настолько резко.е выделение линий, разграничивающих верхнюю поверхность бруса 14 и его кромок 12, 13, что эта лини четко обнаруживаетс с помощью сигнала, генерируемого фотоэлек-трическим регистратором 2. Фотоэлектрический регистратор 2 выдает сигналы на вычислительный блок 6, св занный с исполнительным механизМОМ (на чертеже не показан), .управл ющий лентами 9, 10 и регулирующий рассто ние между пилами 15, 16, которое в соответствии с размерами досок по- ширине может мен тьс . Управление включением источников света 1 осуществл етс с помощью блока 7 . синхронизации, который св зан с вычислит зльным блоком и коммутатором переключени источников света:. Соединенный с рефлектором 3 генератор 5 импульсов, подключенный к вычислительному блоку 6, выдает периодический сигнал, используемый., во-первых , дл синхронизации источников света в процессе обработки доски и по-вторых, дл указани местоположени обследуемых точек по длине бруса , другими словами, дл создани координатной оси, с которой соот-. носитс сигнал фотоэлектрического регистратора 2.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.
Таким образом, введение в конструкцию устройства сканирующего рефлектора блока синхронизации освещени бруса и поворота рефлектора, а также средств установки и ориен-тации бруса позволило получить четкие сигналы, .с высокой точностью указывающие местоположение разграничительных линий в каждой из р да точек без перемещени бруса, а .также обеспечить значительную экономию расходуемого материала.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.
