Description
(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ДИАМЕТРА БРЕВЕН ПРИ ПОДСЧЕТЕ ОБЪЕМА ВЫРАБОТКИ(54) DEVICE FOR MEASURING THE DIAMETER OF A LOG IN WHEN CALCULATING THE VOLUME
на большого диаметра; на фиг,3 схема фотоэлементов со световодами.on a large diameter; Fig, 3 scheme of photocells with optical fibers.
Устройство содержит первый и второй источники 1 и 2 света, расположенные по одну сторону измер емого предмета 3, фотоэлементы 4 первого р да и фотоэлементы 5 второгр р да, 1 расположенные по другую сторону измер емого предмета, световоды 6, состо щие из параллельных пластин, в которые помещены фотоэлементы 4 и 5 первого и второго р да, причем световоды 6 с фотоэлементами 4 направлены к источнику 1 света, а световоды 6 с фотоэлементами 5 - к истонику 2 света, что исключает попадание света на фотоэлементы соседнего р да .The device contains the first and second sources 1 and 2 of light located on one side of the measured object 3, photo cells 4 of the first row and photo cells 5 of the second row, 1 located on the other side of the measured object, optical fibers 6, consisting of parallel plates, The photocells 4 and 5 of the first and second rows are placed in, the light-guides 6 with the photo-cells 4 are directed to the light source 1, and the light-guides 6 with the light-emitting cells 5 - to the source 2 light, which excludes the light entering the photoelectric cells of the neighboring row.
Устройство работает следующим образом .The device works as follows.
При отсутствии измер емого бревна 3 первый источник 1 света освещает все фотоэлементы 4 первого р да, а второй источник 2 света - все фотоэлементы 5 второго р да. При по влении измер емого бревна 3, диаметр которого не превьшает значени , соответствующего середине диапазону измерени (фиг.1), затемн етс часть фотоэлементов 4, освещенных первым источником 1 света, а все фотоэлементы 5 продолжают освещатьс вторым источником 2 света. При измерении предмета 3 с диаметром, превышсшхцим значение, соответствующее середине диапазона измерени (фиг.2), затемн ютс все фотоэлементы 4 первого р да и часть фотоэлементов 5 второго р да, освещаемых вторым источником 2 света.In the absence of a measurable log 3, the first light source 1 illuminates all photocells 4 of the first row, and the second light source 2 illuminates all the photocells 5 of the second row. When a measurable log 3 appears, the diameter of which does not exceed the value corresponding to the middle of the measurement range (Fig. 1), part of the photo cells 4 illuminated by the first light source 1 is darkened, and all the photo cells 5 continue to be illuminated by the second light source 2. When measuring an object 3 with a diameter exceeding the value corresponding to the middle of the measurement range (Fig. 2), all photo cells 4 of the first row and part of the photo cells 5 of the second row, illuminated by the second light source 2, are darkened.
После срабатывани фотоэлементов 4, и 5 визуально либо с помощью логической-схемы определ етс диаметр предмета.After the photocells 4 and 5 have been activated, the diameter of the object is determined visually or by means of a logic circuit.
Устройство обладает повышенной точностью за счет возможности увеличени числа фотоэлементов. Кроме того, использование двух источников света упрощает устройство.The device has increased accuracy due to the possibility of increasing the number of photocells. In addition, the use of two light sources simplifies the device.
