Наиболее близким по технической сущности является устройство для первичной ¹⁰обработки спиленных деревьев, включающее механизм подачи деревьев, круговое основание, поворотный в горизонтальной плоскости манипулятор с захватом, сучкорезную головку, раскряжевочный узел и накопители для укладки сортиментов [2], Недостатком известных устройств является сложность конструкции.The closest in technical essence is a device for the primary ¹⁰ processing of sawn trees, including a tree feeder, a circular base, a horizontal swivel arm with a grip, a delimbing head, a cutting unit and drives for stacking assortments [2], The disadvantage of the known devices is the design complexity .

Цель изобретения — упрощение конструкции.The purpose of the invention is to simplify the design.

Достигается это тем, что каждый из на- 20 копителей снабжен челюстным захватом и установлен по периферии основания шарнирно с возможностью поворота в вертикальной плоскости при помощи привода, а сучкорез2 ная головка и раскряжевочный узел смонтированы на манипуляторе.This is achieved by the fact that each of the 20 accumulators is equipped with a jaw grab and is mounted pivotally on the periphery of the base with the possibility of rotation in the vertical plane by means of a drive, and the delimbing head and the cutting unit are mounted on the manipulator.

На фиг. 1 изображено устройство для первичной обработки спиленных деревьев, общий вид; на фиг. 2 — конструкция накопителя.In FIG. 1 shows a device for the primary processing of sawn trees, a general view; in FIG. 2 - drive design.

Устройство для первичной обработки спиленных деревьев включает механизм подачи деревьев в виде поперечного транспортера 1, круговое основание 2, поворотный в горизонтальной' плоскости манипулятор 3 со смонтированными на нем захватом 4, сучкорезной головкой 5 и раскряжевочным узлом в виде пильного аппарата 6. С внешней стороны основания 2 концентрично манипулятору 3 смонтированы рамы 7 накопителей. Верхние концы рам наклонены в сторону манипулятора, а нижние — через шарниры 8 опираются на основание. Количество накопителей, как правило, согласовано с числом отпиливаемых типоразмеров сортиментов (обычно на каждый типоразмер предусмотрено, как минимум, два накопителя).A device for the primary processing of sawn trees includes a tree feed mechanism in the form of a transverse conveyor 1, a circular base 2, a rotary manipulator 3 in a horizontal plane with a gripper 4 mounted on it, a delimbing head 5 and a cutting unit in the form of a sawing device 6. From the outside of the base 2 concentric to the manipulator 3 mounted frames 7 drives. The upper ends of the frames are tilted towards the manipulator, and the lower ones, through the hinges 8, are supported on the base. The number of drives, as a rule, is consistent with the number of sawn sizes of assortments (usually at least two drives are provided for each size).

Каждый накопитель снабжен челюстным захватом 9, и посредством гидроцилиндров 10 рама 7 вместе с захватами 9 имеет возможность поворота относительно шарниров в радиальном по отношению к манипулятору 3 направлении. Верхняя часть 11 основания горизонтальна и отделена от рам 7 накопителей вертикальной стенкой 12, концентричной центру крепления манипулятора 3, образуя вокруг него кольцевую зо- j ну, в которой размещены скребки 13, прикрепленные к днищу корпуса манипулятора 3. Между транспортером 1 и основанием 2 установлен продольный транспортер 14 для вершин и крупных сучьев разделанных стволов. Между транспортером 14 и верхней <0 частью 1 1 основания 2 размещен козырек 15 с окнами 16, под которыми установлен ленточный транспортер 17 для выноса мелких сучьев и мусора. Каждая рама 7 снабжена днищем 18, закрепленным перпендикулярно продольной оси 19 накопителя. В конструкции крепления днища 18 к раме предусмотрена возможность ступенчатого перемещения днища по оси 19 в зависимости от длины отпиливаемых сортиментов, например при помощи ряда отверстий 20 и 20 проставок 21.Each drive is equipped with a jaw jaw 9, and by means of hydraulic cylinders 10, the frame 7 together with the jaws 9 can be rotated relative to the hinges in a radial direction with respect to the manipulator 3. The upper part 11 of the base is horizontal and separated from the drive frames 7 by a vertical wall 12, concentric to the mounting center of the manipulator 3, forming an annular zone around it, in which scrapers 13 are attached, attached to the bottom of the manipulator 3. Between the conveyor 1 and the base 2 is installed longitudinal conveyor 14 for tops and large knots of cut trunks. Between the conveyor 14 and the upper <0 part 1 1 of the base 2 there is a visor 15 with windows 16, under which a belt conveyor 17 is installed for the removal of small knots and debris. Each frame 7 is equipped with a bottom 18, mounted perpendicular to the longitudinal axis 19 of the drive. In the design of attaching the bottom 18 to the frame, it is possible to stepwise move the bottom along the axis 19 depending on the length of the cut assortments, for example, using a number of holes 20 and 20 of the spacers 21.

Работа устройства для первичной обработки спиленных деревьев осуществляется следующим образом.The operation of the device for the primary processing of sawn trees is as follows.

Стволы деревьев (хлысты) подаются в виде поперечной щети транспортером 1, где, попадая в зону действия манипулятора 3, захватываются, ставятся в вертикальное положение и переносятся в зону накопителя, предназначенного для приема сортимента, по диаметру, соответствующему захва- 3Q ченному стволу. После этого захват 4 разжимается и ствол за счет потенциальной энергии движется вниз. Во время движения посредством сучкорезной головки 5 производится обрезка сучьев, которые подаются на верхнюю часть 11 основания 2. После упо- ³⁵ра торца ствола в днище 18 накопителя оператор зажимает верхнюю часть ствола захватом 4, ориентирует подлежащий отпиливанию конец ствола по оси 19 накопителя с учетом ранее уложенных в накопитель бре- _<0вен и производит отрезку сортимента, включив пильный орган.Tree trunks (whips) are fed in the form of a transverse brush by conveyor 1, where, falling into the area of operation of the manipulator 3, they are captured, placed in a vertical position and transferred to the area of the drive intended for receiving the assortment, according to the diameter corresponding to the captured 3Q trunk. After that, the grip 4 is unclenched and the barrel moves down due to potential energy. During movement through delimber head 5 is made delimbing which are fed to the upper part 11 of the base 2. After upo- ³⁵ pa in the bottom end of the stem 18 clamps the upper drive operator of the barrel gripper 4, subject to the sawing orients the barrel end of the drive shaft 19 with the previously placed in the drive logs- _<0 veins and produces a piece of assortment, including the saw body.

Оставшуюся часть ствола поворотом манипулятора 3 переносят к следующему на копителю (при необходимости), а при малой сбежистости ствола цикл повторяют над этим же накопителем. Оставшаяся вершинная часть ствола падает на верхнюю часть И основания и при повороте манипулятора за очередным стволом скребком вместе с сучьями передается на козырек и далее уносится транспортером 14. Мелкие сучки и мусор при движении по козырьку 15 через окна 16 попадают на выносной транспортерThe remainder of the barrel by turning the manipulator 3 is transferred to the next to the accumulator (if necessary), and if the trunk is too small, the cycle is repeated over the same drive. The remaining vertex of the trunk falls to the upper part of the base and, when the manipulator rotates behind the next barrel, the scraper, together with the knots, is transferred to the visor and then carried away by the conveyor 14. Small knots and debris when moving along the visor 15 through the windows 16 fall onto the external conveyor

17. По мере заполнения накопителей оператором включается челюстный захват 9 и известными устройствами может производиться обвязка сформированного пакета. После этого гидроцилиндрами 10 рама 7 вместе с пакетом переводится в горизонтальное положение, челюсти захвата разводятся и пакет остается на поверхности, а рама 7 под действием этих же гидроцилиндров 10 переводится в исходное положение для приема следующего пакета.17. As the drives fill the operator, the jaw grab 9 is turned on and the formed packet can be strapped using known devices. After that, the hydraulic cylinders 10 frame 7 together with the package is moved to a horizontal position, the jaw of the grasp is opened and the package remains on the surface, and the frame 7 under the action of the same hydraulic cylinders 10 is moved to its original position to receive the next package.

Применение устройства позволяет механизировать весь комплекс нижнескладских работ и увеличить производительность труда в 4—5 раз.The use of the device allows to mechanize the whole complex of lower warehouse operations and increase labor productivity by 4-5 times.

(54) DEVICE FOR PRIMARY TREATMENT OF SPILLED WOODWORKS The invention relates to devices for the primary processing of sawed trees and can be used in the forest industry. A device for processing sawed trees is known, which includes a base, a tree noddering mechanism, a manipulator pivoting in a horizontal plane, a cutting unit and storage devices for stacking assortments I. The closest to the technical essence is a device for preprocessing sawed trees, including a tree feeding mechanism, a circular base, a horizontal pivoting arm with a grab, a delimbing head, a cutting unit and storage devices for assortments 2. The disadvantage of estno devices is the complexity of design. The purpose of the invention is to simplify the design. This is achieved by the fact that each of the drives is provided with a maxillary gripper and is mounted around the periphery of the base, hingedly with the possibility of rotation in a vertical plane by means of an actuator, and the delimbing head and spreading unit are mounted on the manipulator. FIG. 1 shows a device for the primary processing of sawed trees, general view; in fig. 2 - accumulator design. The device for preprocessing sawed trees includes a tree feed mechanism in the form of a transverse conveyor 1, a circular base 2, a manipulator 3 rotatable in a horizontal plane with a gripper 4 mounted on it, a delimbing head 5 and a cutting unit in the form of a saw unit 6. On the outer side The bases 2 are concentric with the manipulator 3 and the storage frames 7 are mounted. The upper ends of the frames are inclined towards the manipulator, and the lower ends, through the hinges 8, rest on the base. The number of accumulators, as a rule, is coordinated with the number of sawn off sizes of assortments (usually, at least two accumulators are provided for each size). Each accumulator is provided with a maxillary gripper 9, and by means of hydraulic cylinders 10 the frame 7 together with the grips 9 has the ability to rotate relative to the hinges 8 in a direction radial with respect to the manipulator 3. The upper part 11 of the base is horizontal and separated from the frames 7 of the drives by a vertical wall 12, concentric to the center of attachment of the manipulator 3, forming around it an annular zone in which the scrapers 13 are placed attached to the bottom of the manipulator body 3. A longitudinal section is installed between the conveyor 1 and the base 2. 14 conveyor for the tops and large branches of the cut trunks. Between the conveyor 14 and the upper part 1 1 of the base 2, there is a visor 15 with windows 16, under which there is a belt conveyor 17 for carrying out small branches and debris. Each frame 7 is provided with a bottom 18 fixed perpendicular to the longitudinal axis 19 of the accumulator. The mounting structure of the bottom 18 to the frame provides for the possibility of stepwise movement of the bottom along the axis 19 depending on the length of the sawn timber to be sawed off, for example, using a series of holes 20 and spacers 21. The device for the primary processing of sawed trees operates as follows. Tree trunks (whips) are fed as a transverse brush by conveyor 1, where, when they fall into the area of the manipulator 3, they are captured, placed in a vertical position and transferred to the area of the drive intended for receiving the assortment, according to the diameter corresponding to the captured trunk. After that, the gripper 4 is expanded and the barrel moves downward due to the potential energy. During movement, the delimbing head 5 is used to trim the branches that are fed to the upper part 11 of the base 2. After the butt end stops at the bottom 18 of the accumulator, the operator presses the upper part of the trunk with the grip 4, orients the end of the trunk to be sawed along the axis 19 of the accumulator, taking into account log drive and produces a piece of assortment, including a sawing body. The remaining part of the barrel is transferred by turning the handpiece 3 to the next drive (if necessary), and with a low trunk slackness, the cycle is repeated over the same drive. The left part of the trunk falls onto the upper part of the base and, when the manipulator turns over the next trunk, the scraper along with the boughs is transferred to the visor and then carried away by the conveyor 14. The small knots and debris move along the visor 15 through windows 16 to the outboard conveyor 17 As the accumulators are filled by the operator, the maxillary gripper 9 is turned on and known devices can be tied up by the formed package. After that, the hydraulic cylinders 10 frame 7 together with the package is transferred to a horizontal position, the jaws of the gripper are diluted and the package remains on the surface, and the frame 7 under the action of the same hydraulic cylinders 10 is transferred to its original position to receive the next package. The use of the device makes it possible to mechanize the whole complex of Lower-warehouse works and to increase labor productivity by 4–5 times.
