Definitions

  • ABSTRACT A press for continuously producing fiber board, chip board or the like comprising an upper and a lower endless link chain each traveling between a pair of guide rollers rotatable in one direction about parallel horizontal axes, each of said chains consisting of rigid link plates each pivotably connected to the adjacent plates, an endless feed belt surrounding each chain and traveling therewith, a plurality of pressure rollers acting upon the link plates of the inner stringers of both chains, and adjustable hydraulic or pneumatic pressure means acting at least upon each pressure r01- ler for the upper chain, each link plate as seen in the direction of its travel having a length equal to at least twice the distance between the'axes of two adjacent pressure rollers of the same chain so that each link plate of each inner chain stringer will be acted upon by the pressure of at least two adjacent
  • the present invention relates to a continuously operating press for continuously producing chip board, fiber board or the like of a mixture of fibrous material such as wood chips, fibers, cellulose or similar materials and suitable binders.
  • This press is of the type which comprises an upper and a lower endless belt each of which forms a link chain the individual links of which consist of rigid steel plates which are pivotally connected to each other at their longitudinal ends. These two chains are movable around and are tightened longitudinally by guide wheels, preferably of a polygonal peripheral shape, which are rotatable in the same direction about horizontal parallel axes.
  • the stringers of these chains facing each other between which the material is to be compressed are movable along pressure rollers which are rotatably mounted between the upper and lower stringers of each chain.
  • the pressure rollers on the link plates at least of the upper chain are acted upon by the controlled but variable pressure of hydraulic or pneumatic cylinder-'and-piston units which press these rollers in the direction toward the opposite pressure rollers of the lower chain and the link plates thereof.
  • One or more of. these pressure rollers of both chains are connected to drive means for driving the chains at the same speed.
  • Presses of the type as above described have been previously designed so as to act as so-called preliminary presses for merely compressing the loose material to a certain thickness which is thereafter passed to at least one further press in which the fiber or chip board is further compressed to the desired final thickness and heated so as to set and harden the binder of the mate rial.
  • a so-called caterpillar-chain press for continuously producing chip board or the like under pressure or under pressure and heat.
  • a layer of wood chips, saw dust or other comminuted fibrous or cellulose material which is mixed with a suitable binder is at first compressed within a short compression stage between the link plates of two chains to the desired final thickness of the board to be produced and it is then maintained under a uniform pressure so as to prevent any swelling of the material while being set and hardened.
  • the link plates of one chain are guided along a curved path which has such a radius of curvature that the upper and lower endless metal belts which are disposed between the two chains will not be damaged by being bent when passing around their guide rollers or guide drums or within the compression stage in which the adjacent link plates abut at an angle upon each other while pressing upon the endless belts.
  • all link plates of each of the two chains are disposed within a common straight plane and the adjacent plates of each chain are separated from each other by slots of such a narrow width that the metal feed belt of the material while running in a straight direction covers or bridges this slot and will be concavely bent only to an insignificant ex tent.
  • the presses as first described have the advantage over these catepillar-chain presses that they may be made of any desired length since the endless plate-link chains are not merely driven by their guide wheels, but primarily by at least some of the pressure rollers which act upon the inner stringers of the two chains, that is, the stringers which face each other. If such a press should have a great length, it is merely necessary to provide means for positively driving a larger number or all of the pressure rollers.
  • These presses have, however, the disadvantage that, since each rigid link plate of the two chains is acted upon only by one pressure roller, it has the tendency to tilt relative to the adjacent link plates.
  • An additional object of the invention is to provide suitable means for preventing the pressure rollers from being bent under the pressure which is exerted on their ends by hydraulic or pneumatic units.
  • each link plate of the two chains has a length equal to at least twice the distance between the axes of two adjacent pressure rollers acting upon each chain.
  • each link plate of each chain while passing through the compression and setthe adjacent link plates.
  • This also permits the individual pressure rollers to be made of a considerably smaller diameter, for example, a diameter of one half or less than that which was previously required, the hydraulic or pneumatic forces which have to be exerted upon the individual pressure rollers may be considerably lower and be more accurately controlled and the link plates do not have to be as thick, heavy and solid as they had to be when each link plate was acted upon only by one pressure roller.
  • the endless feed belts which travel along with and around the link plate chains and then directly between the inner stringers of these chains for feeding the loose fibrous material continuously toward and between these stringers and for then transmitting the pressure which is exerted by the pressure rollers upon these inner chain stringers and through the latter during the compression and setting stages upon the opposite sides of the fibrous material will not be subjected to very high stresses and may therefore consist of relatively thin and flexible belts of steel, plastic, andsuitable fabric, netting, or the like. Furthermore, the wearing plates which were required in some of the known continuously operating presses betwen the pressure rollers and the like plates may now be omitted entirely.
  • These bracing means preferably consist of smaller rollers which act upon the main pressure rollers at least centrally of their length and, in turn, are acted upon by hydraulic or pneumatic units similar to those which act at least upon the upper pressure rollers.
  • bracing rollers should also be provided for all those lower pressure rollers which are vertically opposite to the upper pressure rollers which are supported by such bracing rollers. If only the upper or lower pressure rollers would thus be supported, the stresses and wear upon the bearings of the opposite unbraced rollers might become excessive.
  • these bracing rollers are preferably provided in pairs at equal distances from the vertically longitudinal plane of the respective pressure roller so that, as seen in cross secion, this pressure roller will have a uniform three-point support by the lines of engagement with the two bracing rollers and the line of its engagement with the respective link plate of the upper or lower chain.
  • FIG. 1 shows a side view of the press according to the invention, some outer parts of which are broken away to show the inside of the press;
  • FlG. 2 shows a cross section which is taken along the line ll ll of HG. 1; while FIG. 3 shows a cross section which is taken along the line lll ill of FIG. 2.
  • the press according to the invention essentially consists of two frames 1 and 2 on each of which an endless link chain 3 or 4 is mounted which is composed of link plates 19 or 20, respectively, which are of equal length and are pivotably connected by link pins or hinges to each other.
  • Each of these chains is surrounded by an endless feed belt 7 or 8, respectively, which preferably consists of thin fexible steel, but may also consist of plastic or a suitable fabric or a screen material.
  • the inner stringers of the chains 3 and 4 that is, those facing each other, directly engage upon the corresponding parts of the belts 7 and 8 and are adapted to take along and drive these belts at the same speed.
  • Chains 3 and 4 and belts 7 and 8 are mounted so that between the sides of the belts which are directly acted upon by the opposite chain stringers 19 and 20 a slot is formed in which a layer 21 of chips, fibers or the like is compressed between the belts 7 and 8 to form a chip or fiber board of a certain but adjustable thickness.
  • Each of the opposite end parts of belt 7 is movable along guide rollers 7 the axes of which are disposed substantially within a semicircle, and the right end part of the lower belt 8 is similarly movable along guide rollers 8, while the left end part of the lower belt 8 which also serves for feeding the layer 21 of fibers or chips to the press is guided by a guide drum or by similar guide rollers which are not shown in the drawings since for this feeding movement of the lower belt 8 toward and into the press, they are spaced at a certain distance from the press as shown in FIG. 1.
  • the guide wheels 13, 14 and 15, 16 for these chains which are mounted on parallel horizontal shafts 9, 1t) and ll, 12, respectively, are made, for example, of a hexagonal shape and each straight outer surface of each of these guide wheels l3 to 16 has a length substantially corresponding to the distance between the link pins or the like which connect each chain link to the adjacent links of the same chain.
  • the inner stringers 5 and 6 of the two chains 3 and 4 are pressed toward each other by pressure rollers 17 and 18 which also drive the two chains and the belts 7 and 8 thereon and are rotatably mounted in corresponding positions opposite to each other so as to engage upon the upper side of the stringer 5 of the upper chain 3 and the lower side of the stringer 6 of the lower chain 4, respectively.
  • the lower pressure rollers 18 may be rotatably mounted in fixed bearings and their axes are disposed within a common horizontal plane
  • the bearings of each of the upper pressure rollers 17 are connected to and preferably mounted on and vertically movable by adjustable hydraulic or pneu' matic cylinder-and-piston units.
  • a certain number of these upper pressure rollers 17 at the inlet side of the machine form a compression stage in cooperation with the opposite lower rollers 18 by being controlled so that each of these rollers exerts a higher pressure upon the inner stringer 5 of the upper chain 3 than the preceding roller so as to effect a successive compression of the layer 21 of fibers, wood chips, or the like until it has the final thickness of the fiber or chip board which is to be produced.
  • the subsequent upper pressure rollers 17 together with the opposite lower rollers 18, the intermediate inner stringers 5 and 6 of chains 3 and 41 and the intermediate parts of belts 7 and 8 form the setting stage of the machine, that is, the stage in which the binder in the previously compressed fibrous material is set and hardened.
  • These subsequent upper pressure rollers 17 are movable by their hydraulic or pneumatic units toward these lower rollers 18 only so far that the slot between the parts of the belts 7 and 8 subsequent to the compression stage will have a uniform thickness and the surfaces of these belt parts will extend parallel to each other up to the outlet end of the machine from which the fiber or chip board is delivered.
  • the diameters of the pressure rollers 17 and 18 are made of such a size that during the travel of the two chains 3 and 4 each link plate 19 and 20 of these chains will engage with and be acted upon by at least two laterally adjacent pressure rollers 17 and 18, respectively.
  • Each link plate 19 and 20 therefore has a length equal to at least twice the distance between the axes of two adjacent pressure rollers 17 or' 18, respectively. Consequently, each link plate 19 and 20 will at all times be acted upon by the pressure of at least two upper pressure rollers 17 and two lower pressure rollers 18, respectively.
  • the outer stringers of the two link chains 3 and 4 are adapted to be heated by suitable heating means, for example, by gas burners 22 and 23.
  • suitable heating means for example, by gas burners 22 and 23.
  • the endless belts 7 and 8 surrounding the link chains 3 and 4 may be heated, for example, by electric heating plates 24 and 25.
  • FIG. 2 illustrates a pair of opposite pressure rollers 17 and 18 of the setting stage of the pressure subsequent to the pressure rollers 17a to 17d of the compres sion stage.
  • These rollers are rotatably mounted in bearings 26, 27 and 28, 29, respectively.
  • each upper and lower pressure roller 17 and 18 is supported at the center of its length by a pair of bracing rollers 30 and 31 or 32 and 33, respectively, as shown in FIGS. 2 and 3 but not visible in H6. 1.
  • bracing rollers are rotatably mounted in bearings 34' and 35 or 36 and 37, respectively, which, in turn, are mounted on the piston rods 38 or 39 of hydraulic 0r pneumatic units the cylinders of which are mounted on fram e 1 or frame 2, respectively. These units are therefore controlled so that the line of engagement of each pressure roller 17 or 18 with the respective link plate 19 or 211 will at all times be straight and the opposite sides of the slot between the parts of belts 7 and 8 on the link plates 19 and 20 upon which the respective pressure rollers act will always be parallel to each other, as seen in the direction of the length of each pressure roller.
  • Suitable adjustable control means should also be provided for the hydraulic or pneumatic units acting upon the bracing rollers 30 and 31 or 32 and 33 and upon the bearings 26 and 27 of eachpressure roller 17 or 18 for insuring that the finished fiber or chip board delivered by the machine will have the desired uniform thickness.
