Description

The utility model relates to equipment of the woodworking industry for the production of wood products, mainly parquet boards from parquet blanks.

Known combined equipment of the company Lurem Machines (France), combining the functions of 6 machines: saw, planer, planer, milling, grooving and tenoning (see the magazine "Tree.ru" No. 5, 2007, p.17) .

However, its multifunctionality is aimed at the needs of industries specializing in the manufacture of piece joinery and furniture, and is not intended for the mass production of wood products.

There are also known lines for the automation of individual technological operations in the manufacture of natural wood parquet, for example:

- an automated line for the format processing of parquet products with the formation of a groove and a crest at the edges and ends (see ibid., pp. 74-75). The line includes two double-sided tenoning or format-cutting machines, combined with a 4-sided longitudinal milling machine through an angular transmitting device;

- an automated production line for glued board, including a device for splicing a parquet board from short lengths of wood onto a toothed spike, a cutting machine for cutting workpieces of the required size, a calibrator, a face layer stacker and a hot press for gluing the package as a whole (see ibid., p. 73- 74);

- an automated splicing line along the length (see the magazine “Tree ru”, No. 2, 2009, p. 68, Fig. 4), including a blank loading shop, a conveyor for feeding them into a single-sided tenoning machine, where blanks are trimmed and milled spikes. After applying glue to the spikes, the workpieces are conveyed by the conveyor to the device for lashing the whips and then to the splicing press.

The disadvantage of such lines is the impossibility in the complex to automate the entire process of manufacturing parquet boards: starting from the operation of loading parquet blanks into the drive and ending with the release of a usable parquet board.

The task of creating a utility model is to master the production of high-quality long-length Nika parquet boards using modern automated high-performance equipment using end-to-end technology, starting with the loading operation of parquet blanks in a line and ending with the release of suitable products.

The goal is achieved with the help of the Nika integrated automated production line for parquet boards, including a drive for parquet blanks combined with a tenon cutting machine for cutting the ends of parquet blanks into a microchip, a device for preliminary forming a set of parquet blanks into a parquet board, parquet board splicing press, profile and planer and calibration and grinding machines, tenoning machines for grooving and combing parquet boards around the perimeter, drives, tilters and conveyors.

This arrangement of equipment in line corresponds to a comprehensive (end-to-end) technology for the manufacture of long parquet boards.

The tenoning machine for cutting the end face of parquet blanks into a microchip performs one-sided cutting of the first and last links of the spliced parquet board, two-sided cutting of its remaining links and is equipped with a built-in mechanism for applying glue to the cut microchip.

The device for preliminary formation of a set of parquet blanks is configured to form each parquet board as a long product of the same length.

The preliminary profile of the parquet board is formed by a profile planing machine simultaneously from all sides in one pass, and the final working profile of the board is formed on tenoning machines in the sequence of cutting grooves and ridges first at the ends of the board, and then on its sides.

At the same time, the calibration and grinding machine is installed in a line in front of the tenoning machines for groove and crest cutting along the width and length of the parquet board.

Figure 1 shows a block diagram of a utility model of a comprehensive automated line for the production of flooring boards "Nick" with a specific arrangement of its equipment.

The complex automated production line for the Nika parquet board (Fig. 1) includes a drive for parquet blanks 1 combined with a tenoning machine 2 for cutting the end face of parquet blanks into a microchip, a splicing device 3 sets of parquet blanks into a parquet board, a splicing press 4 parquet boards, profile-planing 7 and calibration-grinding 11 machines, tenoning machines 13, 14 cutting the groove and crest of the parquet board around the perimeter, drives 5, 9, tilters 8, 12 and conveyors 6, 10 parquet boards.

The tenoning machine 2 has a built-in mechanism 15 for applying glue to the chopped microchip. Calibration-grinding machine 11 in accordance with the manufacturing technology of the parquet board is installed in line in front of the tenoning machines, double-sided 13 and 3-sided 14.

The line works as follows. In the drive 1 load six pieces of pre-dried parquet blanks of exactly the same length, high quality - without knots, delamination cracks, burrs. Moreover, all blanks are selected the same cut (radial or tangential). The capture of the drive 1 moves the parquet blanks alternately at the same interval to the tenoner 2.

Moving the conveyor of the machine 2, the parquet blanks pass the first cutting head, which cuts the workpieces to the same length and makes a shoulder, the second cutting head cuts at the ends the microchip necessary for splicing the parquet blanks into a long product - a parquet board.

At the same time, the tenoning machine automation is set up so that the ends of the first and last links of the future parquet board are cut on one side, and on all intermediate links the ends are cut on both sides. This sequence of cutting the ends of the individual links of the spliced board will allow in the future to form its lengthy workpiece.

The tenoning machine 2 is equipped with a mechanism 15 built into it for applying glue to one of the cut ends of the links at the exit of the machine, skipping the last link.

Next, the links of the parquet board with adhesive applied to the cut ends enter the device 3 for the preliminary formation of a set of parquet blanks in a long product. At the same time, the preformed parquet board turns out to be of standard length, the same for all subsequent boards.

The formed parquet board from the device 3 by longitudinal movement enters the splicing press. Moving along the press, the board reaches the stop and all glued and connected into a single unit are pressed against it with a certain force, providing a single length, standard for all spliced parquet boards. In this case, the press clamp 4 is triggered and finally forms a spliced parquet board of a given size. From the press 4, the parquet board gets to the conveyor of the drive 5. The speed of the conveyor 5 is slow, which allows the glue to dry out and create a certain supply of spliced parquet board for the continuity of the work of the profile planing machine 7, where the board gets by the piece, moving by conveyor 6.

Machine 7 has four cutting heads that process a parquet board from 4 sides simultaneously in one pass, forming a preliminary profile of a parquet board having a rectangle of a given size in cross section. The processed parquet board from the profile planing machine 7 falls onto the conveyor-tilter 8, from where it is turned over with a 180 degree flip. (from the back to the front surface) and enters the drive conveyor 9. The functions of the drive 9 and its operating mode are similar to drive 5.

From the drive 9, the parquet board, by the piece (face up), will fall onto the conveyor 10, accumulating on it in sufficient quantity and fed to a calibration and grinding machine 11, the working body of which is three belt-type grinding calipers with different sizes of abrasive used. Here is the mechanical finishing (calibration and grinding) of the front surface of the parquet board. Calibration-grinding machine 11 is installed in a line in front of the tenoning machines 13, 14 of groove and comb cutting along the width and length of the parquet board and allows already at this stage of its manufacture to obtain the required quality of processing of its front surface.

From the machine 11, the conveyor-tilter 12 turns the parquet board (turns over) 180 degrees, falling into the double-sided tenoning machine 13 (face down) in which the groove and the comb of the ends of the board are cut. From the machine 13, the parquet board enters the three-side tenoning machine 14, in which the groove and the crest of the board are cut along its length and its thickness is leveled by processing the back surface. In this case, the roller clamp rigidly fixes the board in the cutting position, since it is very important to cut the groove and comb along the entire length of the board, while simultaneously ensuring its predetermined thickness.

Machines 13 and 14 finally form the working profile of the parquet board. When passing the machines 13 and 14, the parquet board lies face down so that when cutting along the perimeters of the grooves and ridges, the ground surface of its front layer is not damaged.

Leaving the machine 14, the parquet board in the form of finished products is fed to the packaging.

The technical result of the utility model consists in the fact that the Nika integrated automated line allows producing parquet boards using end-to-end technology, starting from the operation of loading parquet blanks into a line and ending with the release of usable products.

At the same time, this line provides both high productivity and the required quality of processing the front surface of the parquet board with a minimum of maintenance personnel.
