Definitions

  • the invention relates to a method of the type corresponding to the preamble of claim 1 and corresponding double belt presses.
  • the wood particles are flat chips, but also other particles created by chopping wood, e.g. by planing, chopping, sawing, grinding or defibrating, which are provided with a binder in the form of a thermosetting synthetic resin and are piled up or sprinkled into a mat or a fleece.
  • the mat is pressed between the surfaces to form a plate-like or similar shaped part, the surfaces being heated and heat being transferred from the surfaces to the mat in order to raise the temperature, to bring the binder to harden and to form the mat into a compact plate or to solidify.
  • the "surfaces" are the pressing plates or sheets in a multi-tier press and the two belts in a double belt press. Instead of flat surfaces as in the two aforementioned cases, there are also presses with a large drum and a steel band wrapped around it for the production of thin plates.
  • the plasticization which the wood fibers or chips experience under the combined effects of pressure, heat and the carefully controlled moisture present in the mat, plays an important role in the failure of the product.
  • DE-OS 35 38 531 which deals with a so-called calender press of this type with a heated press drum spanned on part of its circumference by a steel belt running over guide and pressure rollers, has already described that the nonwoven preferably at the beginning of the press nip compressed to a value in the range above or below the nominal thickness of the finished plate and then enclosed between the heated press drum and the steel belt while being transported further until the particles are continuously converted into their plastic state and the binder has been brought to the required curing temperature.
  • the measures described are intended to achieve a good board surface by means of a single pressing operation and, at the same time, due to the increased compression at the beginning of the pressing, better heat transfer in the chip layer and faster penetration the heat can be achieved in the outer areas of the compressed chip layer. Details of the pressure and temperature control are not apparent from DE-OS 35 38 531.
  • This double belt press has a flat part of the support structure which is adjustable by pivoting about a transverse axis and delimits the inlet section. A particularly quick and strong compression of the mat cannot be achieved here.
  • the press has an adjustable first part of the support plate, but if the steepness of the position were sufficient to achieve the desired rapid compression, the forces that would occur would be so great that they endangered the press and would no longer transmit the necessary propulsive force from the forming belts could be, not to mention the sharp kink between the steep first part of the press plate and the press plate in the main press section, which would destroy the forming belts.
  • the invention has for its object to design the generic double belt press so that wood chips and similar panels of different structure can be produced on it with tolerable load.
  • the tray can ensure that the mat comes into contact with the two forming tapes substantially simultaneously.
  • the tray initially keeps the mat away from the forming belt underneath and only releases it onto the lower forming belt at a desired point in time.
  • the desired surface improvement itself promoted because the mat is not preheated for a long time from below (as in the exemplary embodiment of DE-PS 21 57 746), but also the substantially uniform formation of the top and bottom of the plate possible.
  • the inlet gap is delimited by the protruding support plates, the form belts conforming to the curvature of the support plates and striving apart at the inlet so that the mat only comes into contact with the form belts in the inlet is coming.
  • the part of the support plate adjoining the bulge of the inlet gap can be pivoted together with the bulged part in order to form a variable inlet. This is particularly important in practice because it allows different plate structures to be produced with the same machine. If the essentially flat part of the support plate is set parallel or essentially parallel to the opposite support plate, the compression takes place rapidly in the area of the bulging part and the caliber is then held, as is the case in the important application of producing thin MDF (Medium Density) Fiber Board) boards with smooth and particularly tensile surface layer is desired.
  • MDF Medium Density
  • fibreboards from 2.5 to 5 mm thick with a specific weight of 600 to 900 kg / m3, which can be used in the furniture industry without surface grinding, for example for cabinet heating and drawer bottoms, but also for painting and as a base for Laminates.
  • the features of the invention work together in the manufacture of MDF panels in that the mat provided with the binder is compressed very rapidly under the influence of the setting temperature which is transferred from the surfaces to the outer layers of the mat, and so quickly that when the full compression is reached, the inner zones of the mat are not yet on higher Temperatures have been warmed.
  • the outer layers are already plasticized and compliant and cling to the surfaces with compression and formation of a smooth surface, while the inner zones are not yet plasticized and offer a correspondingly high compression resistance. With this compression, the outer layers are subject to a peak pressure that is higher than if the mat was continuously at a high temperature and then compressed to the same final thickness. The compression must therefore be reached before the inner zone of the mat warms up.
  • the plasticization and hardening which then initially only takes place on the outside, not only increases the smoothness, but also the hardness and tensile strength of the surface layer. As the action of pressure and heat continues, the latter also penetrates into the inner zone and there leads to plasticization of the wood particles. Since the caliber, that is to say the existence between the surfaces, is then essentially kept, there is no progressive compression on the inside, but instead hardens the mass at an essentially constant, lower density.
  • the essentially flat part of the pivotable support plate is swung open so that it forms an inlet gap which narrows steadily in the running direction with the opposite support plate, then none occurs abrupt compaction with subsequently held caliber, but a gradual compaction as the warming of the inner zones of the mat progresses.
  • a plate can be produced which is essentially constant in its properties over the thickness.
  • Such panels are used in the furniture industry for cabinet doors or cabinet side surfaces in a thickness of the order of approximately 20 mm, and are often subjected to subsequent milling to produce folds or decorative surface reliefs. In order for the milled surface to have properties that are as constant as possible, the milling cutter must find the same material properties at all milling depths.
  • the double belt press in question meets both of these requirements without having to make any changes other than simply adjusting the infeed area.
  • the position of the transverse axis relative to the opposite support surface can also be adjusted in order to be able to adapt the transition to the actual pressing section as required.
  • Embodiments of double belt presses with variable infeed are known from DE-OS 24 48 794 and DE-ASen 10 09 797 and 23 43 427, although in the latter case the support plate, in contrast to the invention, should be just elastically deformable.
  • this time must be approximately 0.1 to 2 seconds (claim 2) in order to achieve the desired To achieve board structure, with thin MDF boards 0.15 to 0.5 seconds.
  • the compression of the mat should be carried out in one go within the abovementioned short time to practically the final thickness of the plate.
  • the running distance which corresponds to the aforementioned time and within which the highest compression must be reached, depends on the advance speed of the forming belts, which can vary considerably in individual cases, for example 30 m / min for plates of 3 mm thickness and 10 m / min for panels 16 mm thick.
  • the design of the protrusion in detail is a compromise between the requirements of the process and the technical possibilities of a double belt press.
  • the process for the production of MDF boards requires a quick compression of the mat in order to achieve the preferred compression in the board surface. This is opposed to the fact that the forming tapes, which provide the advance of the mat under the pressing pressure through the pressing section, are under considerable longitudinal tensile stress, which is still superimposed on the bending stresses when the forming tapes bend. So that the yield stress range is not reached, especially at elevated temperatures, there is a lower limit of the permissible radii. A rule of thumb is that a radius of 400 mm must not be exceeded per millimeter of strip thickness.
  • the form tapes used in practice have a thickness of about 1.5 to 2.0 mm, the smallest radius is in the range of 600 to 800 mm, from which the diameter of the deflection drums of about 1500 mm which is usually used is derived from that of smallest occurring radius of the bulge should be substantially the same (claim 3).
  • the inlet gap does not have to have a purely circular longitudinal section, but can also be one of the Circular shape have slightly different, steady shape. The only important thing is that the permissible smallest radius is not fallen below at any point and the desired rapid compression is nevertheless achieved at a given working speed.
  • a heat shield may also be necessary, for example in the area before the inlet where the hot form tape faces the unprotected surface of the mat and the precautions could be taken to prematurely start the hardening without precautions (claim 5).
  • the double belt press designated as a whole in FIG. 1 with 400 comprises a lower forming belt 1 and an upper forming belt 2 made of sheet steel of approximately 1.5 mm thickness, which endlessly rotate one above the other in a vertical plane.
  • the shaping belts 1, 2 are deflected via deflecting drums 3, 4 which correspond to two further deflecting drums (not shown) on the right outside of FIG. 1 and whose bearing points are displaceable for the purpose of tensioning the shaping strips.
  • the upper run of the lower forming belt 1 and the lower run of the upper forming belt 2 lie one above the other at a short distance and form pressing surfaces between which the mat 10 is pressed together according to a certain time program.
  • the forming belts 1, 2 run in a horizontal, essentially flat pressing section 38, 5 at the same speed in the same direction indicated by the arrow 18.
  • a mat 10 of wood chips provided with binding agent which is located between the shaping belts 1, 2, is exposed to the action of pressure and heat and cured to form a coherent plate web P (FIG. 6).
  • the form belts 1, 2 are driven via the deflection drums.
  • the deflection drums 3, 4 shown are heated and have a heat-conducting surface, so that the heat is transferred to the forming strips 1, 2.
  • the heating is dimensioned in such a way that the shaping tapes 1, 2 reach a temperature during one revolution around the deflecting rollers 3, 4, which is sufficient to harden the layers 10 of the mat 10 locked between the shaping tapes 1, 2 adjacent to the shaping tapes 1,2.
  • a lower support plate 6 is arranged in the pressing section 38, 5 below the upper run of the forming belt 1 and an upper support plate 7 above the lower run of the upper forming belt 2.
  • the support plates 6, 7, in turn, are supported on support structures designated as a whole by 8 or 9, which consist of I-beams 11, which successively follow one another in the running direction and extend across the width of the shaping strips 1, 2, one of which is above and one above the other is vertically opposite below the pressing section 38.5 and is laterally connected to the outside of the forming belts 1, 2.
  • the pressure is applied by hydraulic pressure elements 12 arranged between the support structure 8 and the lower support plate 6, by means of which the caliber, ie the distance between the mutually facing strands of the shaping belts 1, 2 in the pressing section 38, 5, can also be controlled.
  • the press section 5 can be 10 to 20 m long; 1, a whole number of carrier pairs 11, 11 follow to the right.
  • the support plates 6, 7 form an inlet gap 13 which narrows in the running direction of the forming bands 1, 2.
  • the deflection drums 3, 4 have moved as close as possible to the inlet gap 3.
  • the mat 10 is not deposited by the spreading device, as usual, on the upper run of the lower forming belt 1, which would then be brought out much further to the left. Rather, the formation of the mat takes place in another way, and the mat 10 is brought up via a tray 30 which extends in the running direction 18 into the inlet gap 13. The mat 10 slides from the tray 30 over its front edge 31 onto the lower forming belt 1 and is then carried along on it.
  • the actual pressing section 5, in which the forming belts 1, 2 run essentially parallel, is preceded by an inlet section 37, which is considerably shorter than the pressing section 5 and, in the exemplary embodiment shown, a part 38 with flat support plates 6, 7 extends over a length of six pairs of beams 11, 11, and includes an upstream inlet section 50 which extends only over the length of a pair of beams 11 ⁇ , 11 ⁇ and in which the support plates 6, 7 are bent apart so that the outermost, ie 1 and 2 left ends of the convex against the incoming into the inlet gap 13 mat 10 bulging parts 6 ', 7' with the plane of the mat 5 include angles of about 40 °.
  • the curved parts 6 ', 7' are evenly bulged against the mat 10, ie they form partial cylinder surfaces with a radius which corresponds approximately to the radius of the deflection drums 3 and 4, respectively.
  • the support plates 6.6 'and 7.7' are in one piece or in any case connected to one another to form a rigid unit.
  • the form belts 1.2 do not run approximately parallel, but obliquely from above and below into the inlet gap 13 and nestle from the ends of the bulging parts 6 ', 7' of the support plates 6.7 to them, so that they are from the beginning are in thermal contact with the heated support plates 6,6 'and 7,7' and are already at the required temperature when they come into contact with the mat 10, as is the case at points 34, 35. (Fig. 2)
  • additional heating elements 39 are provided, which are indicated by dashed lines in FIG. 1.
  • the deflection drums 3, 4 can also be heated. If the deflection drum 4 takes over the sole heating of the forming belt 2 and the forming belt 2 is heated up correspondingly high, a heat shield 41 can be attached over the incoming area of the mat 10, so that the mat 10 does not prematurely open on its upper side due to the radiant heat of the forming belt 2 Temperatures are brought at which the curing begins. At point 43, the inlet section 50 merges continuously into section 38, in which the support plates 6, 7 are essentially flat.
  • the transfer and feed zone is drawn out again enlarged in FIG. 3.
  • the front edge 31 of the tray 30 is formed by a cutting-like pivoting member 33 which can be pivoted about a transverse axis 32 at its end remote from the front edge forming the cutting edge. 3, the underside of the mat comes into contact with the hot lower shaping belt 1 at approximately the point 34, while the top of the mat 10 comes into contact with the upper shaping belt resting against the upper support plate 7 at approximately 35 2 starts.
  • the locations 34 and 35 are therefore the locations at which the outermost layers of the mat 10 experience the setting temperature.
  • the locations 34, 35 are not at the same height.
  • the mat 10 By pivoting the pivot member 33 in the position shown in dashed lines down, the mat 10 lowers earlier, so that the point 34 moves to the left and the point 35 to the right and thus the position of the contact points can be changed. If the plate to be produced from the mat 10 is to be made the same on both sides, care will be taken to ensure that the locations 34, 35 are approximately at the same height, viewed in the direction of travel of the mat 10.
  • a tray 30 ' is indicated, the front edge 31 can be adjusted by shifting in the direction of the arrow.
  • the points 34, 35 of the contact of the mat 10 with the hot forming tapes 1, 2 are approximately at the same height.
  • the diameter of the deflection drum 4 is approximately 150 cm and the distance shown in FIG. 3 from the area of the contact points 34, 35 to the apex of the roll gap is approximately 25 cm.
  • 100 of 15 m / min 1.0 seconds are required to pass the distance 36.
  • Fig. 5 indicates the situation in the inlet gap 13.
  • the mat 10 has only been in contact for a short time of 0.1 to 2 seconds with the strands 1 ', 2' of the shaping belts 1, 2 and experiences a strong compression in the inlet gap 13 , while the heat from the strands 1 ', 2' transferred only into the outermost layers 10 'and the middle zone 10' of the mat 10 is still cold. So you oppose the compression a much greater resistance than the chips in the outer layers 10 ', which are already plastic and are highly compressed, which is characterized by the greater density of the lines indicating the chips in the zones 10'. At the same time, however, due to the increased temperature present in the zones 10 ', the binder sets, which is represented by the cross hatching.
  • the lower deflection drum 3 need not be heated.
  • the lower support plate 6,6 ' is as a rigid unit by a right according to Fig. 1, i.e. the pressing section 5 facing the end of section 38 located transverse axis 42 downward by a few degrees from the upper support plate 7,7 '.
  • This is done by corresponding actuation of the pressure elements 12.
  • the transverse axis 42 It is not absolutely necessary for the transverse axis 42 to be formed by a transverse pin attached to the support plate 6, 6 '. It can be an imaginary axis.
  • the inclination of the support plate 6,6 ' results from the setting of the pressure elements 12. This also makes it possible to shift the transverse axis 42 from the upper support plate 7,7' away according to FIG.
  • FIG. 7 The overall view of FIG. 7 reveals the convexly curved inlet section 50, the subsequent flat section 38 and the actual pressing section 5, which is also essentially flat.
  • the support plate 6,6 'according to FIG. 7a is set so that it is parallel in section 38 of the support plate 7.
  • the rapid compression has ended at the end of the inlet section approximately at point 43, at which inlet section 50 merges into section 38.
  • the caliber is essentially maintained, i.e. the support surfaces S1, S2 are parallel to each other at a distance which corresponds to the final thickness.
  • the embodiment shown in FIG. 7a is concerned with the production of a thin plate 2.5 mm thick.
  • the caliber "2.5" is held from point 43 to the end of the pressing section 5, as indicated by the corresponding numbers in Fig. 7a.
