Method and equipment for shaving or similar planing sex - Förfarande och anordning för att good pärtor eller liknande

The invention relates to planing a shingle or the like.

In traditional shaving planes, shingles are planed from logs cut to the desired shank length with a blade that travels back and forth at a certain stroke length. The length of the shingles is thus limited to the maximum stroke length. The blade planes on the shore. forward and then return to plan a new one, and in a conventional planer the blade speed is slow at the beginning and end of the stroke. In this case, the tree 15 tears easily, especially after the branch, according to the causes of the tree, and the cut is not smooth. It also follows that the stem wood must be fresh and thawed. The slow-moving blade breaks the dry shingles into easy cracks, and in icy wood, the shear cut "escapes" in front of the 20 blades and proceeds according to the causes of the wood. The effectiveness of traditional planers is also poor for a number of reasons. First, because the blade speed decreases the impact ·. at both ends and in addition the blade always burns idle,. · back. Second, traditional planers only plan • ··. * / 25 one tree at a time, as it is difficult to hold several short logs *** * at the same time. In addition, the planer • · · '· "runs empty" during a log change, because a new log cannot be • · · inserted until the previous "base" has been removed.

The object of the invention is to provide such a method and apparatus for planing a shingle or the like, *. which eliminate the above disadvantages.

• · ··· • · * ··· * 35 In order to achieve these objects, the invention according to the invention. The method for planing shingles or the like is characterized by what is defined in claim 1. Correspondingly, the apparatus according to the invention for planing shingles or the like is characterized by what is defined in claim 6. In the other claims. various embodiments of the method and apparatus according to the invention are shown.

The invention and some embodiments thereof will be described in more detail below with reference to the accompanying drawings, in which: Figure 1 schematically shows planing means and an arrangement for planing shingles or the like, Figure 2 schematically shows a side view of a method and apparatus according to the invention and Figure 3 top view of an implementation of a method and apparatus according to

Apparatus for planing a shingle or the like comprises; planing devices, the implementation of which is shown schematically in Figure 1. The planing means 3, 4, 8 and ·· 25 9 plan 1 1 of the supported material wood on the base 2, • ·; · 1 flange or the like 6.

The blade 4 is, for example, a blade comparable to a chopper blade, and in testing the invention, a blade made of chopper steel has been used, in which the blade r. the chamfer 5 is ground considerably more gently than what it is ···· in a conventional chipper blade. In the solution according to the invention, the suitable blade angle is in many cases * ·., About 20 degrees, but the blade angle can also be one of the · ·99 • 9 999 98282 3

somewhat larger or smaller. Too large a blade angle will cause the shingle or chisel to break, and reducing the blade angle will again make the blade durable a problem, especially if the wood is knotty. Tools for moving planer-5 VED material timber length to cause the direction of the arrow B.

As already stated above, the representation of Fig. 1 is schematic and merely illustrative, and the planing means suitable for use in the solution according to the invention can be realized in many different ways.

Figure 2 schematically shows an implementation of the method and apparatus according to the invention. In the solution according to the invention, the material trees 1, 1 'can be in succession, and they can in principle be of any length. They are well supported by means 10 suitable for the base 2, for example by slightly concave holding pieces, especially at the junction of the two material trees 1 and 1 ', so as to prevent them from moving both longitudinally and transversely and also from rotating. At the same time, these support means 10 can be used to adjust the height of the trees relative to the base 2. This% is not implemented as a means of moving planing tools. * or run along the material tree. '

. *. * 25 The planing means 3, 4, 8 are pivotally attached from the frame 3 at points l 16 and 12 to the drawbar or arms • · # * · * · 15 and the push arm 11, respectively. Here the tractor • • · * ··· * can be used. normal three-point hitch and arrange it in such a way that the brackets 12 and 16 in the frame 3 and the corresponding brackets 13 and 17 in the tractor 20 form a parallelepiped when viewed from the side: * · *: the position of the blade 4 attached to the frame 3 remains planing means *. when raising and lowering the same. In addition, it is advantageous to provide the pusher arm 11 with means 14, for example a conventional rotary arrangement, by means of which the e 14 can be extended. and shortens the arm 11 to fine-tune the position of the blade 4.

It is essential in the invention that the planing means 5 are driven along the surface 7, 7 'of the logs 1, 1' over the whole log assembly from end to end at a substantially constant speed which can be adjusted. By adjusting the speed, the quality of the resulting surface 6 can be influenced and a suitable or ideal speed can also be found in each case, with which a very smooth planing surface is obtained. The slower the blade advances, the farther the wood cuts in front of the blade according to the grain structure of the wood and the coarser the surface becomes. The quality of the surface depends not only on the speed of the blade but also on the quality of the wood; 15 freshness, type of wood, grain structure, icing, etc. It is clear that the appropriate speed in each case is also substantially affected by the thickness of the planing sheave or the like. In dry or icy wood, cutting progresses faster in front of the blade than in fresh and molten wood, 20 and then a higher speed is required to smoke a smooth surface. Experiments show that when planing suitably fresh pine wood, the optimal speed for achieving a smooth surface • t j is in the order of 30 km / h, when the thickness of the planed ridge or grout is in the order of 5 mm.

·· 25 • · · · It is also essential in the invention that the substance trees 1, 1 '»· ·' * * J are arranged as an arrangement of successions and / or alignments, '• 5. * which is at least several meters long and can be • • ev: tip long. In the experiments, individual shingles and slats longer than 10 meters have been planed. Figure 3 Γ \. illustrates an embodiment of the invention, in which the tractor 20 is further used as the driving means, and in which the material trees 1, 1 ', pre- •. for example, pine logs, are arranged in succession and in parallel so that there are three in parallel between the 20 wheels of the tractor 20 ·· # * • · ’··· 35 and four on each side of the wheels.

The planing means here comprise three different blades 4, 4 'and ··· 9 9 9 · 999 5 98282 411, one for each log assembly, and corresponding stops 8, 8' and 8 ", which on the other hand could well also consist of one long stop. Also the blades could naturally replace a uniform long blade.

The integral frame 3 of the planing means is attached to the tractor 20 by means of pulling and pushing arms 15 and 11 as shown in Fig. 2.

With the solution according to the invention, it is possible to achieve a very high planing efficiency compared to conventional planers. If, for example, in the case of Fig. 3, the planing lines are driven at a speed of 30 km / h, then a burr or grit is formed during the run from 11 material trees in a total of about 90 meters per second. The log assembly can be driven with 15 planer tools in both directions, allowing efficiency to be improved. It is further conceivable to arrange in parallel or otherwise suitably several material-tree arrangements over which the planing means can be driven in succession or by rotation, for example by arranging two parallel long material-tree arrangements, one driven in the forward direction and the other in the return direction. If a tractor or similar is used as the means of transport, then the tree arrangements can be placed quite freely | ti. One possibility is, for example, to arrange parallel platforms so that the logs can be unloaded from the • load of the forestry tractor directly on the platforms on both sides. The collection of the resulting long shingles or flakes: · * can and should be carried out efficiently, ··: * in order to take full advantage of the efficiency of the solution according to the invention, and its own solutions have been developed, which are not described in more detail here.

It is clear to a person skilled in the art that the tractor is only •. . ..... .

35 is an example of driving equipment. If the planing takes place in a permanently located plant, it is advantageous to use electric traction equipment, which can be, for example, moving on rails and to which the transmission can be arranged, for example, by means of gears and racks. The provision of transmission and speed control 5 in such installations is a well-known technique per se, and the implementation alternatives are therefore not considered in more detail here. One skilled in the art will readily be able to see other possibilities for arranging vehicles moving on and / or sideways of a log assembly, and all such possibilities are considered to be within the scope of the invention as defined in the claims below.

As has been shown above, the solution according to the invention can be used very efficiently to produce a pearl or glue which has many other uses than the traditionally planed shingles. The solution according to the invention is well suited for planing a 3 to 7 mm thick shingle or slat, but also 20 somewhat thinner or thicker articles can be made. The surface quality can be adjusted as needed. In addition to pine, birch, spruce, aspen and alder, as well as many other tree species, are also suitable as material. The prepared • glaze or adhesive can be used as a
