Description

The invention relates to the forestry and woodworking industries and can be used for the production of parts of wooden houses from logs / lumber.

A known method of manufacturing parts from bars on a line with programmed control, in which the workpieces are sequentially processed in processing units, moving from one unit to another using conveyors, securing with various positioning devices (V.M. Kuznetsov, V.I. Livshits A.N.Kamionsky, Automatic and Semi-Automatic Lines of Woodworking Production, Moscow: Vysshaya Shkola, 1982, pp. 186-188).

A known line for processing squared parts with software control MOB-2, implemented in this way. The line contains processing units, interconnected by conveying conveyors and feeding mechanisms, loading devices and a lifting table for forming a stack of finished parts.

The disadvantages of the known method of manufacturing parts from bars and a device that implements it are: the need to use a large number of transporting and positioning devices: for moving, turning and fixing the workpieces in front of each processing unit, which complicates the device and reduces efficiency and productivity.

A known installation for the manufacture of wooden parts of a log house, comprising a frame with longitudinal guides for reciprocating movement of the carriage with mounting rails for fixing mechanisms. On the carriage there is a processing head with cutters for turning the log and a mechanism for selecting a longitudinal groove with a mill. The installation is made three-position with transverse movement of the log. In the installation, logs are loaded, the workpiece is turned and the longitudinal groove is made, the transverse grooves are made, the holes are drilled and the ends are cut (lengthwise) (see application for invention of the Russian Federation No. 94005745, MKI V27C 9/04, 1995).

The disadvantage of this solution is the inability to automate the processing of logs / beams and to ensure the required product quality due to the lack of a single end measuring base for parts located at positions and for processing heads, as well as the absence of movable program-controlled processing units.

The closest in technical essence is a method of manufacturing house parts from a log / timber, in which the blanks are delivered individually to the processing center with an automatic metering pusher, where each blank is moved or stopped with this pusher depending on the types of processing performed by the blocks of the processing center: processing of grooves, drilling, grooving, end cuts (“Production technology of log houses” Makron Engineering OY).

A known installation for processing logs / beams "LOGMATIC" that implements the specified method. The line contains a dosing transverse conveyor, a log / beam rotation device, a sliding table, a LOGMATIC processing center, consisting of processing units, conveyors for unloading parts and shipping wastes, an automatic metering pusher.

The disadvantages of this method of manufacturing house parts from a log / beam and installation of its implementation "LOGMATIC" are:

- the need for accurate positioning of the workpiece after each longitudinal movement, which requires the use of a precise meter pusher;

- the possibility of sequential processing of only one workpiece with the subsequent supply through a clear interval.

All this reduces profitability and productivity. In addition, the installation occupies large production areas.

The object of the present invention is to increase the efficiency and productivity of the process of production of houses from logs / beams by automating the process without compromising product quality.

This problem is solved by the fact that in the method of manufacturing house parts from a log / beam, including the supply of a log / beam to the processing area, automatic positioning of the log / beam, processing of groove grooves, drilling, grooving, grooving. Before the log / beam is fed into the processing zone, one base end is processed, grooves are processed at several positions simultaneously with the corresponding tools. Moving logs / beams from position to position is carried out in the transverse direction. The log / beam is based on each position: in the longitudinal direction, relative to the longitudinal base, and in the transverse direction, relative to one end base common to all positions. After processing, the log / beam is sawn with face saws into individual parts.

In addition, the grooving process includes: milling grooved grooves, milling grooves for installing windows and doors, milling elements for a dovetail connection, milling planes for installing platbands, milling elements with a 5-axis milling cutter, longitudinal sawing and angle sawing.

What is new in this method is that before the log / beam is fed into the processing zone, one base end is processed, grooves are processed at several positions simultaneously with appropriate tools. Moving logs / beams from position to position is carried out in the transverse direction. The log / beam is based on each position: in the longitudinal direction, relative to the longitudinal base, and in the transverse direction, relative to one end base common to all positions. After processing, the log / beam is sawn with face saws into individual parts.

In addition, the grooving process includes: milling grooved grooves, milling grooves for installing windows and doors, milling elements for a dovetail connection, milling planes for installing platbands, milling elements with a 5-axis milling cutter, longitudinal sawing and angle sawing.

This problem is also solved by the fact that the installation for the manufacture of house parts from a log / beam contains a dosing transverse conveyor, a device for rotating the log / beam, a sliding table, a machining center consisting of processing units, conveyors for unloading parts and shipping waste. The sliding table is made in the form of a frame with sliding guides fixed on it, in which controlled base stops are installed, controlled pneumatic clamps-pushers for moving the log / beam and a device for rotating the log / beam. The processing center is made in the form of several movable portals located above the sliding table, on which the movable processing units are mounted. The movable portals are mounted on horizontal rails mounted on two beams, each portal being connected to the beams by synchronized servo tracking drives. On the portals, on two sides of the guides, movable carriages are installed, connected by servo drives to the portals. On carriages, on vertical guides, processing units are installed, connected by servo drives with carriages. An end face ruler is installed on one side of the slide table, and pneumatic end clamps are installed on the other side, and a face block is fixed in front of the end face ruler. On the last portal, carriages with blocks of miter sawing of the log / beam into parts are installed.

In addition, processing blocks are installed on the carriages of the movable portals: a block for milling grooved grooves, a block for milling grooves for installing windows and doors, a block for milling elements for the “dovetail” connection, a block for milling planes for installing platbands, a block for milling elements with a 5-axis mill, block longitudinal cutting and block cutting at an angle.

New in this installation is that the sliding table is made in the form of a frame with sliding guides fixed on it, in which controlled base stops are installed, controlled pneumatic clamps and pushers of the log / beam and the device of rotation of the log / beam. The processing center is made in the form of several movable portals located above the sliding table, on which the movable processing units are mounted. The movable portals are mounted on horizontal rails mounted on two beams, each portal being connected to the beams by synchronized servo tracking drives. On the portals on two sides on the rails mounted movable carriages connected by servo drives with portals, on the carriages on vertical guides installed processing units connected by servo drives with carriages. An end face ruler is installed on one side of the slide table, and pneumatic end clamps are installed on the other side, and a face block is fixed in front of the end face ruler. On the last portal, carriages with blocks of miter sawing of the log / beam into parts are installed.

In addition, processing blocks are installed on the carriages of the movable portals: a block for milling grooved grooves, a block for milling grooves for installing windows and doors, a block for milling elements for the “dovetail” connection, a block for milling planes for installing platbands, a block for milling elements with a 5-axis mill, block longitudinal cutting and block cutting at an angle.

The technical result consists in the fact that the proposed set of features leads to the achievement of an unobvious result. Due to the basing of the processed workpieces and processing units with respect to a single base and the simultaneous processing of workpieces located on the sliding table by all processing units, it allows you to automate the processing of parts, at the same time improves the quality of products and increases productivity and production efficiency. In addition, the installation is more compact, due to which the production space occupied by it is reduced.
