Definitions

  • the invention relates to a method and a device for the non-cutting cutting of wooden slats and boards
  • the object of the invention is therefore to provide a new chipless cutting method that is able to cut slats and boards of different thickness from pre-cut squared timber and / or posts or even from wooden slats. This is to be achieved without the disadvantages mentioned above.
  • the non-cutting cutting of the wooden slats and thin boards is achieved according to the invention in that preferably ( (Disc) knives ") which have sharp edges on their circumference and are successively arranged in a tapered, preferably opposite, side, penetrate into the wood block or post, which is preferably still saturated with water, with their cutting edge. Due to the gradually deepening penetration of the following flat-ground (disc) knives, the lamella or thin board is finally completely removed from the wooden base - not abruptly, as is known, but gradually, gently, with a minimum of problematic pre-splitting.
  • (Disc) knives ) which have sharp edges on their circumference and are successively arranged in a tapered, preferably opposite, side, penetrate into the wood block or post, which is preferably still saturated with water, with their cutting edge. Due to the gradually deepening penetration of the following flat-ground (disc) knives, the lamella or thin board is finally completely removed from the wooden base - not abruptly, as is known, but gradually, gently, with a minimum of problematic
  • the pre-splitting is already with this non-cutting system when the individual (sliding) knife hits the wood due to the small depth of cut small and it reduces to zero when the (disc) knife has reached its greatest depth
  • the separation is achieved in that either the (disc) knife is stabilized Guide device and a drive through wood, or that the wood is clamped on a guide carriage and fed to the (disc) knife and thus separated.
  • the label (Slice) knife "comes from its preferred shape, namely circular - so that it can also rotate when cutting - but mostly only the term knife is used in the following, since this, as explained below, does not necessarily have to have a round shape can also be rigidly attached, ie it does not necessarily have to rotate during the cutting process.
  • the knives which are arranged one behind the other and have exactly the same height are preferably aligned in the horizontal plane.
  • the second, third, fourth, etc., preferably from both sides, into the wood-cutting knives are positioned or dimensioned (center distance or knife size) in such a way that they follow the cut of the previous knife, but deepen it in each case. It should be emphasized that the knives lie exactly in the same plane in order to make the previous cut and to produce a clean cut surface.
  • the depth of cut of the individual knives is adjustable, it depends on the type of wood and its moisture content. This is preferably between 5 and 30 millimeters per knife insert.
  • the knives are preferably made of metal. HSS, HM and. Stellite.
  • the cutting angle of the cutting edge depends on the following factors: if you start from the wood to be cut, it should be as small as possible so that the separated lamella does not kink across the grain and become damaged, if you start with the cutting tool, it should be larger to increase the static load capacity of the knives and the service life of the cutting edges.
  • a sharpening angle of 5 to 15 ° has proven to be advantageous. As a result, tearing parallel to the fiber on the underside of the lamella is reduced to a minimum and the stability of the knives and their cutting edge service life is acceptable.
  • the shape of the knives can be varied in the floor plan: round (disc-shaped), oval, polygonal, corrugated (no cutting teeth) circumferential cutting edge, etc., these shapes have the advantage that the knives can rotate during the cutting process. This creates a cutting speed, it helps the wood fiber more easily without cutting and therefore without cutting.
  • the rotatable knives it is quite possible with the rotatable knives to carry out sharpening work by means of built-in grinding bodies at a point on the knife that is not currently being used for cutting, even during the cutting process.
  • These grinding wheels are preferred intended for wet grinding and can be fed to the (disc) knife if the cutting quality deteriorates. Water is added during the sharpening process in the wet grinding process, so that on the one hand there is no heat build-up on the metal (shortening the tool life) and on the other hand the tiny metal chips are washed away so that the cutting edge is not injured when the cutting operation is carried out at the same time.
  • Another variant according to the invention is to use fixed knives arranged in a step-like manner, here segmental shapes are more suitable, but they have the disadvantage of a short service life because they are always worn in the same place, and they are not rotatable during cutting. and therefore not sharpenable.
  • the relative speed of the feed of the knives compared to the wood to be cut is variable, but is preferably approximately 1 m sec.
  • the cutting speed of the knives can theoretically be zero, since the wood and / or the knives are moved by the feed, cutting the Wood is made, which is the case with fixed knives anyway.
  • the cutting speed is preferably approx. 1 m sec. Compared to the wood to be cut, and preferably in synchronism.
  • the knives must be guided through the wood evenly and with as little vibration as possible; automated delivery is desirable.
  • the guide device and the drive can take place in many variants known in the prior art, is therefore not part of the invention and is therefore not discussed in detail.
  • Fig. 1 shows a wooden body (2) from which non-cutting slats are separated.
  • the knives (1) are arranged on both sides and are tapered in order to separate the lamellae without cutting in the cutting direction (4).
  • the tapering (in the exemplary embodiment, decreasing axis distance) of the knife distances continues until the two last knives completely separate the lamella.
  • the latter knives must be slightly offset so that the cutting edges do not touch each other.
  • the gradual lateral incision of the knives in the preferred embodiment is approximately 1 cm Fig. 1 (3). With a slat width of 10 cm, ten knives, five on the left or right, are therefore necessary.
  • the knives are well attached to the drive shafts and are preferably operated by an electric motor via a gear.
  • the height adjustment (infeed) of the separation device can be done hydraulically, pneumatically, via a threaded spindle and the like. a. m. take place and is preferably electronically programmable. This ensures that the desired slat or board thickness can be set quickly.
  • the feed is effected by a hydraulically operated, guided slide, on which the wood is preferably clamped by vacuum and is fed to the knives.
  • the knives are preferably rotated in synchronism during the cutting process and, if necessary, sharpened with the built-in grinding device on the mirror surface and / or on the bevel of the knife FIG. 2 (3). Both turning the knives and any small shafts (no cutting teeth) on the circumferential cutting edge help to cut through the wood fiber more easily.
