The invention relates to woodworking industry, and in particular to methods of manufacturing the walls of wooden buildings. The inventive method provides for the formation of the geometric shape of logs with imitation of manual cutting and reducing processing costs, makes possible fabrication wooden frames with high performance quality.

The prior art known technical solution according to the patent RU 2324590 C2 from 27.07.2006 "Universal round-shaping machine for processing logs containing composite frame installed on it feed device, a device for the mechanical treatment of wood and exhaust device. The bed is made of two parts with the ability to transport the machine with separated parts of the frame, with the first part of the base hosted the input device, and the second part of the base hosted a device for the mechanical treatment of wood and exhaust device. The disadvantage of this technical solution is the technological complexity of the process, which is not provided complete processing of the product per unit; in addition, the goal of treatment is cylindering, in which the surface layers of the wood are removed, which reduces the quality and durability of the product, as well as the ratio of output of commercial timber.

Known targetenemy decision on patent RU 52760 U1 from 15.11.2005, machine for cylindrical shaping of logs and sample longitudinal grooves, containing a frame with guide rails mounted on the movable frame and the fixed tailstock centers, the carriage drive mechanism to move along the guide rails and mounted on the carriage, the cutting mechanisms cylindrical shaping and sampling longitudinal grooves actuators, and the cylindrical shaping mechanism made in the form of rigidly mounted on the carriage body, the mechanism of selection of the longitudinal grooves made in the form of at least two milling units, installed on the housing for movement to adjust the milling depth. A disadvantage of the known technical solution is that when such processing is performed only operations cylindrical shaping and sampling of longitudinal grooves, which increases the complexity and reduces the performance of the manufacturing of a product, as it requires additional equipment, and several stages of processing to produce the final product.

It is also known technical solution according to the patent RU 68416 U1 30.07.2007, a machine for cylindrical shaping of logs and sample of grooves, allowing the machining of timber cutting mechanisms and the selection of longitudinal grooves for one setting of the workpiece using a movable carriage. However, the disadvantage of this utility model is that the process must p is Emesene logs along the axis of the machine by rollers, installed in the frame, and with the same purpose - to ensure the passage of logs - at least one grandmother made in the form of an arch, which is the complicating elements of the machine and leads to increased labor, materials, and the increase in the cost of a machine and process logs, process logs with the use of this utility model is not final, requires further technological operations machining logs. Also a disadvantage of the known solution is that the mechanical treatment of wood by the method of cylindrical shaping surface layers of the wood are removed, which reduces the quality and durability of the product, as well as the ratio of output of commercial timber.

It is also known technical solution according to the patent RU 2051025 C1 from 31.12.1992, according to which the processing method of logs includes machining the mating surfaces of the logs, including the cutting of the groove. When this processing is done under diameter larger initial diameter of the trunk at a width corresponding to the width of the cut groove, and the width of the handle provides for copying the surface of the rollers. The disadvantage is the inability to ensure uniformity of the final product, which leads to additional work when assembling the frame.

There is a method of manufacture of parts of houses from logs/brosai installation for its implementation in the patent RU 2390410 23.06.2008, by which method includes the supply of logs/timber in the treatment area, automatic positioning of logs/timber, processing ring grooves, drilling, machining grooves face the cut. Thus, before submitting logs/timber in the treatment area is treated with one base edge, the slot machining carried out on several items at the same time the relevant instruments, and moving logs/beams with position is carried out in the transverse direction, the location of logs/timber in each position exercise: in a longitudinal direction relative to the longitudinal base, and in a transverse direction relative to the one end of the base, the total for all items, after processing the log/timber sawn mechanical saws into its individual parts. In addition, in the process of grooves include: milling ring grooves, milling grooves for installation of Windows and doors, milling elements under connection dovetail milling planes for installation of casings, milling elements 5-axis cutter, longitudinal cutting and cutting at an angle. There is a method allows the manufacture of parts made of logs, taking into account sbeinati that allows preservation of the surface layers of wood logs, but the disadvantage is the high energy consumption during processing of the slots, and no University is the codification of the final product, that increases the cost of the Assembly frame. In addition, the installation for the implementation of the known method is special and high-tech units, providing automation of the process, increasing the cost of the equipment, consequently increase the cost of the product.

There is a method of fabrication according to the patent RU 2397860 C1 dated 16.12.2008, including the liberation of wood from the bark and twigs, cut longitudinal and transverse joints, marking of logs in accordance with the project documentation, the Assembly frame. Longitudinal and transverse joints of logs opt for woodworking device in accordance with a pre-designed individual optimal profiles, for which first logs Oberau on site measurement of the geometrical characteristics of the logs, then on the software to determine the mutual location of the logs in the log cabin, and the plane of their contact, taking into account the geometry and the natural taper of sbeg logs, subject to a minimum of machining. The invention improves the accuracy of Assembly of the frame and reduces the consumption of timber. The disadvantage of this method is inevitably high cost of the equipment required for its implementation, i.e. high-tech specialized installation, which uses a sophisticated electronic equipment. In addition,the improved accuracy leads to an increase in processing time, that reduces productivity, and a method of processing logs increases the energy consumption. The disadvantage is that each log after processing has its own form that when the Assembly increases the complexity, i.e. when significant costs associated with automating the process of unification of the items is missing.

The closest to the proposed invention to the technical essence and the achieved result is a method of processing logs and device for its implementation in the patent RU 2282855 C2 from 17.12.2003, which method includes machining the mating surfaces, including the undercut longitudinal groove diameter, the larger diameter of the original logs. The processing of the mating surfaces is performed after processing the surface of the logs due to its rotation about the longitudinal axis of the tool is moved along the guides, and the axis of the log tilted relative to the guides to position the top surface of the log parallel to the guides. The known method allows us to produce parts of the frame, taking into account sbeinati logs, keeping it superficial layers of the wood and increasing the yield of timber, as well as ensuring the standardization of products. The disadvantage of this method is processed by milling, which increases energy and reduces the performance, the AOC is e is also a device for implementing the known method involves the use of metal construction machine using non-standard equipment - geometrically-complex cutters, which leads to higher cost of production and increase the cost of the final product.

The technical problem of the present invention is to improve the efficiency and productivity of the production process houses of logs, also to reduce the amount of wood waste; reduction of energy consumption in the manufacture of the frame; the unification of the final product, maintaining a dense outer layer of wood, which increases the durability of the structure and the resistance of the wall frame. Currently, a large number of forests by timber harvesting, faced with a lack of economic motivation: the low cost of raw logs with the rising costs of harvesting makes their implementation disadvantageous. Treated timber, which is the finished product under the frame, to realize it is much easier and more profitable, but small forestry can not afford expensive equipment, additionally, the energy consumption and equipment costs should be minimal, but the performance is high and at the same time to ensure uniformity of products. This challenge is solved by the present invention.

The technical result of the invention is increased productivity, cost reduction in the manufacture of the wooden frame using mechanical processing b is even, providing unification of the final product, maintaining a dense outer layer of wood, coefficient of output of commercial timber, and also increases the resistance of the wall frame.

The technical result of the invention is achieved by the fact that the claimed method of the manufacture of lumber includes the liberation of wood from the bark and twigs (acoreana), machining the surface of the logs, machining of the mating surfaces, the Assembly frame, in contrast to the prototype sample of a tongue and groove in the mating surfaces are mechanical sawing, shaping the profile of the carriage in places mates logs in the corners with vertical and parallel faces, the formation of the profile of the beam is carried out by mechanical sawing, and the profiles of all interfaces of the same type, which allows to unify the product; sbeinati logs accounted for by changing the size between the top and bottom groove along the length of the logs, acoreana products is carried out in the last turn, reducing the area of processing and sbinet compensated when assembling the logs in the log: Komel-peak, peak-butt. The inventive method does not require for its implementation of costly specialized equipment and can be implemented using the available blocks, packaged in AG is EGAT. For example, to perform the operation for longitudinal processing use the band saw Assembly from the machine, for example of the type PL-60, MG, Taiga T-2 or other, and a circular saw with a diameter of 300-500 mm For transverse sawing used chain saws industrial production professional type. Acoreana is the last operation, so the processing is subjected to the least square logs, which also improves performance. In addition, regular lock the longitudinal axis of the logs can be metal studs hammered into the opposite ends of the logs, and clamp the transverse axis of the stem upright radius logs, drawn from the pin in the end of the log.

The advantages of the proposed method:

- possible adjustment fabrication of any size in plan and logs of any diameter;

unlike cylindrical shaping processing of the logs is preserving sbeinati individual logs and save the most superficial dense layers of wood;

- when assembling the wooden frame of logs made with imitation of manual felling, logs alternate taking into account sbeinati and get a greater wall thickness, respectively, warmer room.

- uniform product allows to establish a continuous method of producing timber;

- increases performance for 8 min one merchantable is and turns into a finished product;

- reduced the energy intensity of manufacturing is due to the replacement of milling sawing operation, in which the unnecessary portion of the workpiece is removed by sawing, but does not translate into chips;

- ability to use inexpensive standard equipment.

Example implementation: mechanical processing of the logs is done for a single installation at a fixed position logs on the stationary frame. All processing steps are performed using a movable carriage with the attached units, providing full cycle of processing, the processing of the workpiece with imitation hand-harvesting is based sbeinati workpiece as by changing the angle of inclination of the workpiece to the frame, and by changing the angles of the cutting surfaces of the saw mechanisms to the axis of the workpiece. Technological processing steps include: sorting of logs, the workpiece, the sample groove V-shaped mechanical sawing. Then there is the change of position of the workpiece in the clamp 180 degrees. Next: forming a V-shaped ridge on the opposite side mechanical sawing, shaping the profile of the carriage in places mates logs in the corners with vertical and parallel faces, then changes the position of the workpiece, the forming of the profile beam mechanical sawing, profile LAF is t and the beam in all places mates logs in the corners of the same type. When processing is taken into account sbinet logs by changing the size between the top and bottom of the groove along the length of the logs. Sbinet compensated when assembling the logs: Komel-top, top-bottom part.

For the implementation of the proposed method make logs with imitation of manual cutting can be used following the design of the machine, containing a frame with guide rails, a movable carriage on rollers, moving on rails, lifting and installation logs, clamps logs, mounted on a movable carriage of the saw mechanisms actuators and clamps the position of each of the saw mechanism. All mechanisms for processing a workpiece mounted on a movable carriage. While on a movable carriage mounted all sawing machines: band saw, mounted on frame with guides, with the possibility of changing the angle of inclination with respect to the guide rails of the machine; chain saw with the possibility of rotation of the working body in the plane perpendicular to the axis of the workpiece; two circular saws, mounted rotatably around an axis parallel to the axis of the workpiece; two circular saws, which are located with a minimum technologically possible offset distance for safe sawing relative to each other; the device installation and configuration of circular saws, with which change is is the angle of rotation; each cutting mechanism has a rotary indexing head with clamp for controlling the position of the cutting tool is thus governed by the angle of approach, the depth of cut is limited by means of stops on the guides; however, the processing of the workpiece with imitation hand-harvesting, i.e. taking into account sbeinati logs is performed by changing the angle of the workpiece relative to the guides of the machine, and by changing the angles of the cutting surfaces of the saw mechanisms to the axis of the workpiece.

The bed is a metal frame on the Foundation with the guides on top. The clamps are designed to secure the workpiece pivotally connected with the frame and operate in a horizontal plane, either as a staff lock the longitudinal axis of the logs can be used metal studs hammered into the opposite ends of the logs, and clamp the transverse axis of the stem upright radius logs, drawn from the pin in the end of the log.

The angle of the workpiece relative to the guide frame changes the supports located on the frame below the guide. Adjusting their height is either manual, or a manual or automatic way. The manual method involves a set of pads; mechanical adjustment takes place by means of screws is or hydraulic Jack; in the case of automatic motor raises the edge of the workpiece, until the work of the height sensor (e.g., laser beam).

All cutting elements of the saw blade mechanisms are mounted on a movable carriage. A movable carriage is a spatial truss frame of metal on four wheels. The mobile carriage moves along the guide rails of the bed plane-parallel relative to the workpiece. On the movable carriage movably attached with the possibility of changing the angle processing two circular saws, frame rails to move the band saw and the band saw, mobile chain saw. The geometric axis of the saw blade mechanisms are movable relative to the movable carriage, the position is controlled by dividing heads, while the band saw is moved relative to the carriage on its own rails. The cutting element of the chain saw is perpendicular to the axis of the workpiece and changes position in the plane perpendicular to the axis of the workpiece for operation facing. Two circular saws for groove sample blanks have the ability to change the angles of the blades to the horizontal plane on the movable carriage. Band saw, recorded in a special position at an angle relative to the moving carriage, is used for formation of the ridge when the ACC is the author of the carriage along the workpiece.

Thus, changing the position of the workpiece relative to the guide frame and rotating the workpiece about its axis, it is possible to carry out sampling tongue and groove log band saw, and two circular saws, with sbeinati procurement, simulating manual felling. Changing the angle between the circular saws and angle of rotation of the workpiece, it is possible to change the sample size of the groove, which is necessary when changing the grade of wood (i.e. when changing the diameter of the workpiece). While the tongue and groove will always be the same size and shape, ensuring consistency of product.

To perform the operation for longitudinal processing use the band saw Assembly from the machine, for example, type PL-60, MG, Taiga T-2 or other, and a circular saw with a diameter of 300-500 mm For transverse sawing used chain saws industrial production professional type.
