Technical field

The invention relates to a device for the longitudinal processing of wood material regardless of its diameter and length.

BACKGROUND OF THE INVENTION

A device for longitudinally dividing tree trunks is known, by cutting two circular saws fixed one above the other in a common cutting plane, which makes it possible to cut trunks of larger diameters, but only in one plane. There is also known a device for longitudinal division of half-timber species, by cutting in several planes by a set of circular saws, but without the possibility of selecting the thickness of the billet and without the possibility to produce e.g. fries with optional dimensions. There are also known devices for splitting wood mass by saw blades according to SK patent no. 277 764, which are arranged in the horizontal and vertical directions, allowing simultaneous sawing of one blade in the horizontal and one blade in the vertical plane. The disadvantage of such devices is that the cuts can only be guided by successive cuttings from one edge of the trunk, which is poorly productive. Also in deeper cuts, especially at the edges of the trunks, there is an imbalance in the cutting system, resulting in dimensional inaccuracy of the cuttings.

SUMMARY OF THE INVENTION

The above-mentioned drawbacks are eliminated by a device for longitudinal processing of wood mass by parallel cuts in vertical and horizontal plane, which consists of a frame placed opposite to each other horizontally and vertically conceivable horizontal saw blades, fixed through shafts on horizontal drive units and also vertical saw blades with limiting rings interconnected to vertical drive units, whose essence is that in the rear part of the frame is located a pair of rear slides with horizontal saw blades and in the front part of the frame is located a pair of front slides with vertical saw blades.

Such a construction of the device allows one cycle not only to make a horizontal cut along the whole width of the trunk, but at the same time to cut the cuttings with a set of vertical discs into plates or prisms of different desired thicknesses. By arranging the slides in the rear and front of the frame, a high degree of system balance is achieved, which ensures high cutting accuracy with a wide range of adjustments of all cutting discs.

BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 schematically illustrates the positioning of the slides and saw blades in the frame of the machine, as well as the cutting engagement of the blades in a certain cutting cycle.

DETAILED DESCRIPTION OF THE INVENTION

The device according to the invention consists of a steel frame 10 (see Fig. 1), in which a rectangular support 11 is movably mounted on its side columns, consisting of a front and a rear part which are fixed to each other by crossbars (not shown in Fig. 1). ). An independent pair of rear slides 91 with fixed horizontal saw blades 3, connected via shafts 8 to the horizontal drive units 1, is hinged to the rear part of the carrier 11. threaded to each other (not indicated in Figure 1). An independent pair of front slides 92 with fixed vertical saw blades 5 connected to the vertical drive units 4 is suspended on the front of the carrier 11.

The first notch in the wood material to be processed 7 is made by horizontal saw blades 3, thereby cutting the top round irregular layer of wood material 7 along its entire length. A further notch is already made after adjusting the thickness of the cuttings by the spacer rings 6 and then simultaneously cutting the horizontal saw blades 3 and the vertical saw blades 5 by cutting the entire length of the trunk. In the event that large-scale wood mass 7 and horizontal saw blades 3 fail to cut the entire layer at the same time, proceed from one side and the other side of the wood mass 7 simultaneously, which is enabled by moving the rear slides 91. 11 in the frame 10 with the slides 91, 92 downwards to the required dimension and the whole process is repeated.

The slides of the horizontal disks 3 are adjustable in the height direction relative to the vertical disks 5 in case the vertical disks 5 are used of a different diameter in order to achieve the cutting plane in both vertical and horizontal position. The speed of the horizontal discs 3 is selected so as to cut the discs from the inside of the wood material 7, thereby extending their service life. The nuts 2 are therefore configured such that one has a right-handed thread and the other a left-handed thread, which prevents their loosening.

Claims (1)
