    (54) ROLLER TARGET FOR THE INVENTION The invention relates to wood processing industry and relates to a roller chain of a continuous press for making wood and similar boards. The famous roller press chain for the manufacture of wood and similar plates, including a series of elastic steel strips arranged transversely permeable material and having rod-like rollers 1 |. The closest technical solution to the present invention is a continuous press roller chain for the manufacture of wood and similar boards, including individual elements, each of which contains rollers mounted on an axis, with adjacent elements connected in a chain by plates, and the end surfaces of the extreme rollers of the elements are located parallel to the planes 2. And for the SSA of the continuous oxidation of wood ŠMG A disadvantage of the known roller chains is that they transfer pressure and heat in a strip-like manner, which entails and a receipt of low-quality product. The purpose of the invention is to ensure uniform transfer of friction and heat. The goal is achieved by the fact that the corresponding heels of the adjacent elements have different levels. The ends of the axles are made flush with the outer end surfaces of the extreme rollers of the elements. In addition, the plates are made in the form of a rectangular z-shaped profile with equal shelves. Extreme rollers in adjacent elements, located on one side of the elements, are longer than the previous rollers, and located on the other side - less than the same size or vice versa.
    Extreme rollers in adjacent elements are longer than the previous rollers, by the same size or smaller length.

    The upper forming belt 1 moves along rollers or drums 5 and 6 located transversely pressed. lane 4. The drum 6 is placed in a fixed bed 7, and the drum 5 in a rotary bed 8, which rotates around an axis and is placed in a support 9. The bed 8 is driven by a hydraulic cycler 10 for tensioning the forming belt.
    The shaping belt 2 moves along the drums 11 and 12 located transversely to the pressable strip 4, the drum 11 being placed in the fixed bed 13, and the drum 12 in the bed 14 moving along the guides. The bed 14 is displaced with the help of a hydraulic cylinder in the longitudinal direction relative to the compressible Band, having carried out the tension of the forming tape 2. The driving of the forming tapes is carried out by the indicated drums.
    The forming belts move in the direction shown by the arrows 15. On the right side of the press, the friable mass 16 is loaded onto the longitudinal section 3 using devices (not shown). The compressed strip 4 leaving the press is removed (Fig. 1) from the left portion of the forming belt 2 by appropriate means (not shown). In the longitudinal section 3 inside the forming belt 1, an upper support structure 17 is provided, which cooperates with a lower support structure 18 placed inside the lower forming tape 2. The structures 17 and 18 serve for clamping with large. force, facing the strip 4, surface areas forming
    tapes 1 and 2.
    The support structures 17 and 18 consist of separate beams 19 and 20, located opposite each other above and below the forming tapes 1 and 2
    and compressible strip 4 (Fig. 2). Each pair of beams 19. and 20 are fastened together by straps at the side and outside the strip, forming closed pressure elements. Strengthening beams between each other
    It is manufactured (Fig. 1 and 3) with screws 21, operating between consoles 22 and 23, connected with end plates 24 and 25, beams 19 and 20. Screws 21 can be equipped with a power drive (not shown). Besides
    In addition, the compression of the beams can be carried out by hydraulic cylinders. The lower beams 20 transmit the force through the filled hydraulic medium pressure pads, ensuring uniform pressure distribution across the entire width of the compression strip (even when the beams 19 and 20 deflect under pressure).
    Each of beams 19 and 20 may be provided with a pressure pad, or such a pillow is attached to several joint beams. Between the beams 19 or the pressure-generating cushion and the forming ribbons 1 and 2 are plates 26 and 27 transmitting to the forming belts. 1 and 2 the pressure created by individual lower elements, and these plates are provided with channels in which heating elements are placed or through these channels flow, heating medium. Roller chains are placed between facing sides of the plates 26 and 27 and the forming tapes 1 and 2, along which the forming tapes 1 and 2 are rolled relative to the plates 26 and 27 and these roller chains move endlessly around the plates 26 and 27 of the vertical plane. Rollers of roller chains transfer pressure and heat from plates 26 and 27 to the forming tapes 1 and 2 and to the extruded strip 4. After the roller chains reach the end of rectifier section 3, they return to the pressing zone between beams 19 and 20 and the plates 26 and 27 of FIG. 2). You can also direct the roller chains around the support structure .18 (FIG. 2). Along the straight section 3, several individual plates may be placed, made similar to plates 26 and 27. For example, it may be preferable to separate the inclined section 28 for chaining formed by the plate 29 from the plate 26, part of which is shown to the left in FIG. 2, and provide two sets of roller chains moving separately around the plate 26 and the plate 29. FIG. 4 and 5 show the first example of the execution of the plates 26 and 27 and the associated roller chains. In this example, the design is provided on a separate plate 30, in which longitudinal grooves 31 and 32 are made on the lower and upper sides, in which roller chains 33 of a general type move, consisting of separate consecutive rollers 34 interconnected placed on both sides of the plates 35 and pins 36. Chains 33 form one branch. At the ends of the plate 3, shaped elements 37 are placed, guiding the roller chains 33 from the lower side of the plate 30 to its upper side and vice versa, therefore the chains 33 can move closed around the plate 30. The shaped elements 37 are fixed to the ends of the plate 30 with the tabs 38. The grooves 31 have greater depth than the height of the rollers 34, whereby the roller chains 33 move freely in these grooves. The grooves 32 have a smaller depth than the diameter of the rollers 34, so they protrude outward on the underside of the plate and 76 can roll on the forming tapes 1 and 2. The rollers 34, in contact with the tapes 1 and 2, also come into contact with the plate 30. Side edges of the grooves 32 serve as side guides for roller chains. These edges (ribs) are superfluous if the roller chains 33 are located adjacent, in this case only one guide is required on the edge of the plate 30. In order to position the roller chains close to each other, a different design of the upper side of the plate 30 is required. plate 30 has transverse heating bar 500, the ends of which are connected to pipelines for supplying heating medium to plate 30, the heat of which is necessary for curing the mass forming the strip 4. To prevent heat loss, between the upper side of plate 30, The heat insulating intermediate plate 41 is attached to the supporting structures 17 or 18 and the sides of the beams 19 or 20 facing the same plate 30. In FIG. 6 and 7 depict a second embodiment of plates 26 and 27 and roller chains. The plates 26 and 27 consist of a heating and support plate 42 and a reciprocally moving plate 43 separated from it. In the plate 42 there are heating channels 40, the ends of which are connected by pipe bends 44, forming a closed circulation system. Plate 42 has no grooves, and its bottom side is flat. Roller chains 45, which directly abut one another, move between this flat bottom side and the forming belt 1. The side restraints of the plate 43 are formed by the direction of the slats 46 for all roller chains 45 forming separate branches 47. Since the roller chains rest one against the other, from the reverse movement on the upper side of the plate 42, according to the first embodiment (Figures 4 and 5) appears impossible because there is no space for partitions between the grooves. Because of this, a separate plate 43 is provided for the return movement, which is more than twice as thick as the diameter of the roller rollers.
     45, and on the side of the plate 43 facing the beams 19 and 20, there are grooves 48 for the reverse movement, and on the side facing the plate 42 there are grooves 49 also for the reverse movement. The grooves 48 and 49 are disposed relative to each other and transversely relative to the compressible strip, due to which the lateral limiting surfaces 50 are arranged vertically one above the other. Otherly, therefore, the respective bounding surfaces of the adjacent roller chains 45 are located in the same plane. The force is transmitted through an intermediate zone 51, which is formed because the thickness of the plate 43 exceeds the doubled diameter of the rollers.
    At the end of the plate 42, shaped elements 52 are provided, guiding roller chains 45 from the lower side of the plate to its upper side and vice versa, and for adjacent roller chains 45 these shaped elements have different radii of deflection so that roller chains 45 fall into all grooves 48 and 49 located at different heights.
    In the second version (Figs. 6 and 7), it is provided that air pressure is somewhat higher than atmospheric within the running-around of the roller chains 45 to prevent ingress of dust and the like. in the specified zone. For this, a casing 53 is provided between the beam 19 and the forming tape 1, which is tightly connected to the supporting structure and sealed relative to the moving forming tape around the entire perimeter by seals 54. Compressed air is fed into the resulting closed space through the air line 55. The seal 54 should not be tight, it is sufficient if a slight excess pressure is maintained inside the closed portration.
    The adjacent two roller chains 33 and 45 move forward independently of each other. The set of supporting elements forms a field divided by moving in the longitudinal direction of the individual branches of the chains (Fig. 8). The individual branches 56 are displaced relative to each other in the longitudinal direction with a corresponding load, due to which
    no force may be generated by the forming belts. Separate branches 56 formed by chains 33 and 45 cover the entire bearing area.
    The area of the fit corresponds to the chains 33 of the aggregate of the strips overlapped by the rollers 34. When using lamellar chains (Fig. 4 and 5), there remains an area 57 on which the forming strips 1 and 2 pass freely and which is not rolled by the rollers 34. The area (section) is not can be made as narrow as possible since the plates 35 are constantly between the rollers 34. Although in this case the forming tapes 1 and 2 are directed (deflected) by the reels 5, 6, P and 2, but they are rather rigid and therefore in zone 57 at not too high pressures no harmful deflections occur and the thermal conductivity of the mold strips 1 and 2 is sufficient for the rollers 34 to equalize the transmitted tag in separate bands for its further transfer to the compressible strip 4.
    However, there are cases where uniform application of high pressure is required and the temperature difference should be minimal. In these cases, the arrangement of the circuits according to FIG. 4 and 5 does not give the required results.
    For these cases, chains have been developed which have no gaps between the rollers. Chain 58 (FIG. 9) contains connecting plates bent at a right angle and rollers 59 and 60 of different lengths which are arranged alternately according to the bends of the plates, due to which the outer parallel limiting surfaces 61 and 62 remain parallel to each other. However, the intermediate spaces 63 between the rollers in which the plates are located have lateral displacement relative to each other due to the curvature of the plates 64. The intermediate space between the previous rollers 59. and 60 (Fig. 9) is rolled by a rolling roller 59 if the chain 58 moves upwards.

    Another embodiment of the chain is chain 65 with straight plates 66 (Fig. 10). The straight plates 66 do not form a straight line parallel to the movement of the chain, but are displaced in one direction relative to each other. So, for example, plate 67 (Fig. U) is displaced upward relative to plate 66, and plate 68 is upward relative to plate 67. Plate 69 is displaced downward relative to plate 68, and four more plates displaced downward are adjacent to them. - Subsequent plates with scheny up. Thus, the entire plate branch is positioned inside the chain in a zigzag manner, whereby the intermediate space that is not rolled by any two rollers is rolled by subsequent rollers. The branches formed by the plates 66 are opposite to the branch formed by the plates 70, which are displaced relative to each other in the opposite direction to the plates 66 Each link 65 consists of three rollers whose width varies periodically and all links of this chain form a branch with parallel restrictive surfaces 71 and 72. Every three rollers of one link are held by a bolt 73, the head 74 of which is recessed in the countersink 75 and does not protrude beyond the bounding surfaces 71 and 72. The chain 65 is similar to the chain shown in phi . 6 and 7. Neighboring circuits 65 are in contact with their end surfaces 71 and 72, which eliminates gaps that do not create pressure. The distances (gaps) between the individual rollers of the chain links are periodically rolled by subsequent chain rollers, thus achieving a uniform effect of pressure on the pressing surfaces, i.e. forming tapes 1 and 2. Chain 76 (Fig. II) is an example of a chain in which the drawback is eliminated, consisting in the presence of bands that are not subjected to pressure. The design of circuit 76 is similar to that of circuit 65, but the plates 77-79 are offset only in one direction relative to the plates located in front. The parallelism of the end surfaces 80 and 81 is created by the different length of the individual rollers. After a certain gap containing several rollers, the upper branch 82 of the plates approaches the edge and therefore the roller 83 is made narrow (short). At this point, the plate-shaped branch 82 is interrupted and a wide (long) roller 84 is placed here, overlapping the total length of both rollers 83 and 85 placed behind it and located in the next branch 86 of the chain. At the lower edge of the chain 76 (FIG. 11), the plate branch 87 is removed from the lateral bounding surface of the chain 76, with the chain link with roller 88 located in front of roller 83 having a length corresponding to roller 84. Only two rollers 89 are attached to roller 88 and 90, between which a new branch 91-chains begins. On the other side, roller 89 is inserted into a chain branch 87. Thus, a jump takes place here, where the branches 82 and 87 of the chain are replaced by branches 86 and 91. In the execution of the side restricting surfaces of the rollers, the chain 76 corresponds to the chain 65. In all chains 58, 65 and 76, the outer rollers are installed so that they allow direct interconnection of individual branches located nearby. All of these chains are placed in a pressure device. They can also be used where uniform, flat description, rolling or contacting is required. Claim 1.
