Definitions

  • the invention relates to a method and an apparatus for cutting a tree trunk into wood products without cutting, in which the tree trunk is guided in the axial direction past at least one mass which splits a wooden product, preferably a side board, from the tree trunk, one of which Adjustable radial force is applied to the surface of the log ⁇ .
  • one of the frames is arranged fixed in space, while the other frame can be adjusted in the radial direction to the tree trunk by means of hydraulic piston-cylinder units, so that the movable frame can be pressed against the tree trunk with predetermined pressure.
  • a pressure bar is arranged on each frame in front of each knife.
  • the radial distance between the pressure bar head and the cutting edge of the knife is constant, so that the knives and the pressure bars can only be pressed against the tree trunk as a whole as a result of the radial movement of the movable frame.
  • the pressure bars in the known device therefore only have the function of guide bars, which also follows from the fact that the pressure bars are arranged on the radially undeliverable frame.
  • the known device therefore has the disadvantage that pressure can only be exerted by the pressure bar if the pressure bar protrudes radially over the cutting edge of the respectively associated knife. Then the pressure exerted by the pressure bar can no longer be freely adjusted because radial pressure changes Deflection of the pressure bar (increase of the contact pressure) would also change the radial position of the associated knife and thus the section thickness.
  • a method and a device for cutting wood and wood-based materials are known.
  • side pieces which have the thickness of small parquet slats are cut off from a wooden blank without cutting.
  • the wooden blank is guided axially by means of a mechanical dovetail guide, and a cutting knife set in vibration movements cuts off a lateral region of the wooden blank.
  • a radial pressure bar is provided which is adjustable in the radial direction and presses in front of the front edge of the cutting knife onto the wood blank which has not yet been split .
  • a similar method is also known from DE-C-25 14 901, in which logs are to be broken down into boards without cutting.
  • swinging knives are also used, which are staggered in the radial direction and arranged one behind the other in the direction of advance of the round wood, in order to successively split side boards from the raw wood.
  • a pressure bar is used, which is arranged on the back of each of the knives and presses sideways on the raw wood shortly before the interface of the subsequent knife. The contact pressure of the pressure bar is therefore the same as the cutting pressure of the knife and is therefore not variable.
  • the known methods and devices have in common that the respective pressing tools, pressure bars or the like, which press directly on the round wood directly in front of the knife edge, rest there with an essentially constant pressure and in a constant position with respect to the knife, which at most more or less by eye - set at the beginning of the machining process. becomes.
  • the known methods and devices in some cases expressly accept that the splitting and the associated radial deformation of the side boards cause macroscopic and microscopic damage to the boards, which are at best compensated for by the subsequent bending devices with regard to the dimensional accuracy of the boards.
  • boards produced by chipless cleavage generally have a lower mechanical stability than boards which have traditionally been produced by means of gang saws or the like.
  • the invention is therefore based on the object of a method and a device of the type mentioned to further develop in such a way that damage to the side boards when cutting off from a tree trunk without cutting is largely avoided.
  • the object is achieved according to the method mentioned at the outset by the fact that the force exerted by the pressing tool and / or its position on the tree trunk, viewed in the direction of advance of the tree trunk, can be set in front of the knife independently of the force exerted by the knife during the splitting-off
  • the object is achieved in that the pressure beam is provided with an adjustable adjusting device which is independent of the knife.
  • the object on which the invention is based is completely achieved in this way because it has become possible for the first time to ensure, by means of a precisely metered contact pressure and positional adjustment of the pressure bars, that the particular circumstances of the particular processed wood are taken into account, taking into account the set process parameters.
  • This essentially has the advantage that hydrodynamic processes in the capillaries of the wood can advantageously be controlled in the interior of fresh wood or drier wood in such a way that the effect of pre-splitting and damage to the wood composite can be minimized by deflecting at the interface. In this way, an optimal compromise can be found between the conflicting demands to set the contact pressure of the pressure bar as high or as low as possible.
  • the aim is to achieve the highest possible pressure and proximity to the knife in order to prevent the wedge gap created by the knife from running too far in front of the knife edge and creating a tear in the wood, while on the other hand one wishes a large distance from the knife in order to to achieve a low contact pressure and around that Bend the side board at the height of the cutting edge of the knife as gently as possible.
  • the pressure and the position of the pressure bar are adjusted optimally with regard to the respective application and independently of the position and the pressing force of the knife, and can also be variably set while walking through a tree trunk, these can be adjusted combine the two conflicting boundary conditions to an optimal compromise.
  • the force can be adjusted according to the amount, the axial or radial point of application or the direction.
  • An oscillating movement of the pressing tool in the radial and / or axial direction is particularly advantageous.
  • the force is set along a predetermined course.
  • the tree trunk can set a predetermined force profile along the tree trunk axis on the pressure beam. This setting can take place either as a function of time or as a function of the axial position of the knives on the tree trunk, which is more expedient.
  • the force is set alternatively or complementarily or position depending on the measured values determined on the tree trunk or on the finished wood product.
  • This measure has the advantage that even tree trunks can be processed sensitively and individually, in which parameters of interest vary along the axial length of the tree trunk.
  • measurements of interest for example temperature, moisture or color of the wood
  • the measured values can also be measured on the finished or unfinished wood product, for example a side board. Tolerances that have crept into the wood product can then in setting the path / force characteristic of the pressure beam ein ⁇ related w 'ground.
  • the wood product in order to produce a finished wood product, is glued to another wood product on its gap side.
  • the wood product and the other wood product are symmetrical in cross section and glued to one another in such a way that the glue plane is in the plane of symmetry.
  • This measure has the advantage that the gap side with the damaged fiber structure is in the so-called neutral plane of the wood product, which is not subjected to any stress when the wood product is subjected to bending stress. This has the consequence that the bending stability of the invention produced Finished wood product can be as great as the bending stability of finished wood sawn in a classic manner.
  • the wood product and the other wood product are split in pairs from the same tree trunk and glued to one another on their gap sides.
  • This measure has the advantage that a particularly uniform process can be implemented in which the wood products are split off from the tree trunk, for example on opposite sides, and then glued to one another on their gap sides.
  • the gap sides or the glue plane are in the plane of symmetry, so that the bending stability of the finished wood product is also optimal in this case.
  • the wood products are fed to bending devices after they have been split off.
  • This measure has the advantage that a rough alignment can take place before the gluing and possibly pressing of the wood products, but without the bending process having to be carried out as intensively as was the case with the already prior art.
  • the wood products are fed to the heating devices after they have been split off.
  • This measure is used advantageously when the wood, as is useful for splitting, is still relatively moist, because on the other hand, a drier wood is desired for gluing the wood.
  • a particularly good effect is achieved if, from the same tree trunk and in the feed direction, several wood products are split in pairs and glued in pairs to finished wood products.
  • This measure has the advantage that a tree trunk can be completely cut into wood products in one pass. It is also advantageous if the processing of the wood products after splitting takes place at a lateral distance from the feed axis of the tree trunk.
  • Another important advantage of these exemplary embodiments is that when wood products are glued in pairs to form a finished wood product, the wood products naturally have to be split off from the tree trunk by half the thickness than is necessary in comparison to conventional sawing methods in order to produce finished products of the same thickness. If an essentially cylindrical tree trunk is broken down into thinner slices, this also results in better utilization of the wood, because the circular cross section of the tree trunk is naturally better filled by lining up thin slices side by side than by comparatively few thick slices, in particular for mass production of wood products produced according to the invention this means that the higher investment endings for the gluing and pressing of the wood products compared to classic sawing systems can be amortized in a short time by a higher wood yield.
  • suitable device measures are required in each case. These include in particular axially or radially directed piston-cylinder units, which are used to adjust the pressure beam and to set a certain force.
  • the last-mentioned group of exemplary embodiments of methods according to the invention can be carried out with particular advantage on a device in which, seen in the direction of advance of the tree trunk, behind knives for splitting off the wood products, a gluing station arranged on the gap side of the wood product and a press are provided.
