Definitions

  • the present invention relates to a procedure as defined in the preamble of claim 1.
  • the invention also relates to an apparatus as defined in claim 10.
  • Elongated particles such as chips or fibres
  • structural products e.g. boards made of wood material, especially OSB boards (oriented strand board).
  • OSB boards are fabricated from relatively large chips of different lengths, which are scattered in suitable orientations onto a base together with a binding agent and pressed to produce boards.
  • the chips in the surface layers are usually oriented in the longitudinal direction, i.e. in the direction of the longer side of the finished product, while the chips in the middle layer are oriented in the transverse direction or they are not oriented at all.
  • separate orienting equipment is used for the surface layers and for the middle layers. This requires relatively large investments on equipment. Moreover, the equipment currently used requires a large space.
  • the object of the present invention is to achieve a completely new type of procedure and apparatus for the fabrication of a blank for a structural product, which make it possible to avoid the drawbacks of prior-art solutions.
  • the procedure and apparatus of the invention have numerous significant advantages. Now it is possible to handle OSB chips of all sizes and lengths and orient them e.g. in transverse and longitudinal directions using the same unit. This makes it possible to produce OSB boards at considerably lower investment costs than before.
  • the space requirement and energy consumption of the apparatus of the invention are considerably lower than in conventional solutions.
  • the material to be scattered may contain relatively short particles and these can be scattered on a desired part of the board and, if necessary, they can be oriented in a given direction. This allows e.g. better utilisation of the raw material.
  • the apparatus of the invention the material can fractionated better than before and therefore better scattering and orienting results are achieved. These circumstances signify that the quality of the final product is also improved.
  • smaller particles can be used than at present without impairing the strength or rigidity of the product or its stability against deformation.
  • the particles are brought onto the base 10 in given orientations so that at least part of the particles are oriented in a direction substantially different from the direction of orientation of other particles.
  • at least part of the particles is oriented substantially in the longitudinal direction of the base 10 and part of them is oriented in the transverse direction relative to the base 10.
  • At least one surface layer A 1 (Fig. 3) of mainly longer particles L is brought onto the base, and smaller particles F, S are brought onto the first layer to form one or more middle layers B 1 , F 1 , F 2 , B 2 , upon which at least one more layer of longer particles L is brought to form a second surface layer A 2 .
  • Fig. 1 shows two scattering/orienting units, the first one of which is used to form the lower layers A 1 , B 1 , F 1 of the blank 10 while the second one is used to form the upper layers.
  • F 2 , B 2 , A 2 The dimensions of the figure are not in proportion to reality but they have been modified for the sake of clarity.
  • an actual product such as a structural board
  • an actual product is obtained by pressing the blank in a press.
  • the middle layer B 1 , F 1 , F 2 , B 2 is transversely oriented relative to the direction of advance of the base 10 while the surface layers A 1 , A 2 are longitudinally oriented.
  • the material 1 to be processed is conveyed onto a preliminary roller set 3 in a blank former, to be screened mainly by particle length.
  • a preliminary roller set 3 in a blank former, to be screened mainly by particle length.
  • At this stage, at least part of the material being screened falls down below the plane formed by the rollers through the gaps between them while the possible remainder is passed down over the tail end of the roller set 3.
  • At least part of the material falling down below the preliminary roller set 3 through the gaps between the rollers, screened by an intermediate roller set 5 placed under the preliminary roller set, is passed via an orienting mechanism 6, 7, 8 onto the scattering base 10.
  • the smallest particles F, S are passed down below the plane formed by the intermediate rollers 5 through the gaps between the rollers of the intermediate roller set 5 while the longer particles L are passed down over the tail end of the roller set 5 via the orienting mechanism 6,7,8 onto the scattering base 10.
  • the orienting mechanism 6,7,8 part of the particles is oriented substantially in the longitudinal direction of the base and part of the particles is oriented in the transverse direction of the base.
  • the longer particles L are fractionated by length before being oriented and/or scattered.
  • the longer particles L are oriented by means of orienting elements 8, preferably longitudinally relative to the track.
  • the shorter particles S and particles F smaller than these are fractionated by size before being oriented and/or scattered.
  • the shorter particles S and possibly part of the smallest particles F are mainly transversely oriented by means of orienting elements 6,7 when brought onto the scattering base 10.
  • the smallest particles F are scattered onto the scattering base 10 in such a way that the shorter they are, the closer to the final middle layer of the board to be pressed they are positioned in the mat formed on the scattering base.
  • the particle size F,S,L typically increases from the middle towards the upper or lower surface.
  • the smallest particles F are brought onto the base so that they are mainly placed in the middle layer in the cross-section of the structural product blank and that their amount decreases towards the surface layers as seen in the cross-section of the blank.
  • a symmetrical blank for a structural product is obtained.
  • Fig. 3 shows a part of the blank sectioned at point C.
  • Fig. 2 presents one scattering/orienting station.
  • scattering/orienting stations are used in pairs, one being used to bestrew the lower side of the board and the other to bestrew the upper side.
  • the scattering/orienting station depicted in Fig. 2 is used to bestrew the upper side of the blank.
  • Fig. 2 thus presents one of the scattering/orienting stations included in the assembly illustrated by Fig. 1, in which the material 1 to be processed, comprising longer L and shorter S particles, preferably such as longer and shorter chips and/or fibres, and possibly even smaller particles F than these, is supplied by means of a feed conveyor onto an accelerating roller 2 rotating at a high speed.
  • the accelerating roller 2 is provided with a suitable rough surface pattern so that it hurls the material to be screened onto a preliminary roller set 3, which consists of at least two substantially parallel rollers 3, preferably rotating and placed in a substantially horizontal plane with gaps between them, allowing part of the material being processed to fall down through the gaps between the rollers while the rest is passed out via the tail end of the roller set 3.
  • the gaps between the rollers may be individually adjustable, for instance in the way described in patent application FI 922777. In a preferred case, the gap width increases towards the tail end of the preliminary roller set 3.
  • the accelerating roller 2 and the preliminary rollers rotate in the clockwise direction as seen in the drawing.
  • the structure of individual rollers in the preliminary roller set 3 may be e.g. like that described in patent application FI 950518.
  • the intermediate roller set 5 Disposed below the preliminary roller set 3 is a set of intermediate rollers 5, extending through at least part of the length of the preliminary roller set from its beginning as seen in the direction of material supply.
  • the intermediate roller set 5 consists of at least two substantially parallel rollers, preferably rotating and placed in a substantially horizontal plane. Between the rollers 5 there are gaps, allowing part of the material being processed to fall down through the gaps between the rollers while part of it is passed out over the tail end of the roller set.
  • the gaps between the rollers in the intermediate set may also be individually adjustable, e.g. as in patent application FI 922777. In a preferred case, the gap width increases towards the tail end of the preliminary roller set.
  • the rollers may have a patterned surface, which may be a milled, faced, glued or similar type of grooved and patterned surface.
  • the roller set may also consist of so-called disc rollers, in which case each roller is provided with discs disposed or formed at a distance from each other and having an outer diameter larger than the outer diameter of the rest of the roller.
  • the discs of adjacent disc rollers may be disposed in an interlapping arrangement.
  • an orienting mechanism Disposed below the preliminary and intermediate roller sets is an orienting mechanism, which comprises orienting elements 6, 7, 8, such as orienting rollers, some of which have been arranged to orient particles coming from the preliminary roller set, possibly via the intermediate roller set, in the transverse direction and some are arranged to orient particles in the longitudinal direction.
  • orienting elements 6, 7, 8 such as orienting rollers, some of which have been arranged to orient particles coming from the preliminary roller set, possibly via the intermediate roller set, in the transverse direction and some are arranged to orient particles in the longitudinal direction.
  • guide elements such as guide vanes or the like may be provided.
  • the apparatus of the invention works as follows.
  • the material 1 to be processed is brought to the beginning of the preliminary roller set.
  • the accelerating roller 2 hurls the material onto the preliminary roller set 3, where the rotation and roller structure of the preliminary rollers cause the material to move on.
  • material of elongated shape tends to be so oriented that even narrow particles cannot fall down through the gaps between the rollers too early.
  • the rotating rollers, especially in the forepart of the preliminary roller set cause long particles to rise up from the gaps between the rollers, thus preventing them from falling down too soon, whereas shorter particles S, F can fall down through the gaps between the rollers and thus land on the intermediate roller set 5.
  • the shorter particles are fractionated by means of the intermediate roller set 5, preferably by size, so that the smallest particles are allowed to fall down through the gaps between the rollers in the forepart of the roller set into the space below the rollers while the largest particles fall down via the tail end of the roller set.
  • the use of an intermediate roller set 5 makes it possible to prevent the longer chips from being intermingled with the shorter chips and, on the other hand, it allows controlled fractionation of the smallest particles.
  • the apparatus is preferably provided with a chip orienting mechanism 6, 7, 8 placed below the roller sets 3, 5.
  • the orienting mechanism preferably comprises, as seen in the material feed direction, a first set of orienting elements 6, designed to orient shorter particles S, F, and a second set or orienting elements 7, designed to orient longer particles L and/or S.
  • the first and second orienting rollers 6, 7 are arranged to orient particles in a direction substantially transverse to the direction of motion of the base.
  • Placed after the first and second orienting elements is a set of third orienting elements 8, designed to orient mainly longer particles, in the case illustrated by the figure in a substantially longitudinal direction.
  • the orienting mechanism may also comprise other types of orienting elements besides rollers.
  • orienting rollers for transverse orientation comprise walls 13, 14 disposed in the lengthways direction of the roller on the roller circumference, forming compartments between them.
  • Placed in the immediate vicinity of the roller circumference is typically a guide wall 11, 12 extending over part of the circumference, so the longitudinal axis of the particles is oriented in the direction of the roller wall while the guide wall keeps the chip in the compartment. In this case, the chip falls onto the base in transverse orientation.
  • the elements 8 for longitudinal orientation of particles may consist of e.g. disc rollers, in which case each roller is provided with discs disposed or formed at a distance from each other and having an outer diameter larger than the outer diameter of the rest of the roller.
  • the discs on adjacent disc rollers may be disposed in an interlapping arrangement.
  • the scattering base 10 is a scattering belt conveyor, whose direction of motion is from left to right.
  • a structural product blank as illustrated in Fig. 3 such as a blank for a structural board, from material comprising longer L and shorter S particles and possibly particles F smaller than these, such as chips and/or fibres, and a binding agent, said blank consisting of two surface layers A 1 , A 2 and at least one middle layer B 1 , B 2 , F 1 , F 2 , between them.
  • the surface layers mainly contain longer particles L, S while the middle layer mainly contains shorter particles S, F.
  • the middle layer thus also contains the smallest particles F, the amount of which diminishes from the middle towards the surface layers A 1 , A 2 as seen in the cross-section of the blank.
  • the particles in the surface layer A 1 , A 2 are typically mainly oriented in the longitudinal direction.
  • the particles in the middle layer B 1 , B 2 , F 1 , F 2 are typically mainly oriented in the transverse direction. Typically, at least part of the smallest particles F is also oriented.
  • the smallest particles F are generally smaller than about 25 mm (1"), preferably under 6.25 mm (1/4").
  • the longest particles L are typically 75 mm - 150 mm (3" - 6") long.
  • the shorter particles are typically under 25 mm - 75 mm (1" - 3") long.
  • the particle lengths and their distribution in the structural product blank depend on the material used and on the structural product blank and its intended use.
