Definitions

  • This invention relates to continuous presses of the type including endless loops formed by longitudinally and transversely flexible conveyor belts which form opposed, substantially linear spans defining a pressing zone. Means are provided for rotatively driving one or both of the loops to drive the spans in the same direction, and press platens apply pressure through the traveling spans to the work carried therebetween. Antifriction means are interposed between the platens and the spans for obvious reasons.
  • Such presses are used for the manufacture of wood-chip board, laminated products, minerally-bonded construction boards or plates, for sintering sheets of polytetrafluorethylene, etc.
  • the flexible belt spans through which the pressing pressure is transmitted may locally flex and stretch unpredictably, and the above-mentioned anti-friction means should be capable of operating satisfactorily under such random stressing conditions. Similar conditions are not encountered by either roller or ball bearings in general, because rigid bearing races apply the load uniformly throughout the rolling elements.
  • the object of the present invention is to provide a continuous press of the type described, which is improved in that its antifriction elements are substantially free from flexure and skewing stresses, and which can be made at a manufacturing cost that is commercially acceptable.
  • the flexible conveyor belts are used, in particular, belts made of strip steel having a gauge in the area of 1 mm. thickness. This has the advantage of low cost, imperviousness and effective heat and pressure transmission properties.
  • a multiplicity of rotatively unpowered endless loops of roller chains are used, these being packed transversely together to form a bed interposed between the platens and the steel strip conveyor belts.
  • the chains are not only unpowered, but also each chain is individually free to travel independently with respect to the others as well as the belt spans themselves. For a belt width in the area of 2 or 2.5 meters, more than of these chains may run side-by-side, each individually free to adopt any traveling velocity independently of all of the others. Each chain is free to change in velocity with respect to the steel belts.
  • the individual rollers are, for all practical purposes, entirely free from horizontal flexure and skewing stresses caused by belt flexure or stretching because each roller is so very short in length individually and does not span the belt areas under deformation. Skewing forces are translated into individual accelerating and decelerating velocities of the various chains. Flexure stresses only result in the chains moving relative to each other.
  • Standard, light-weight machinery roller chains may be used.
  • a successful experimental machine embodying the above features located in Germany uses a chain roller diameter of 12.77 mm. This would generally correspond to American Standard ASA light weight machinery chain, designated as No. 41, having a nominal roller diameter of 0.306 inch, or possibly No. 40 having a 5/16 inch roller diameter.
  • the roller width of No. 41 is A inch, and of No. 40, it is 5/16 of an inch.
  • the roller length should not be very much greater than the roller diameter although this relationship may be exceeded to meet special circumstances providing the roller length is not so great as to span the localized belt deformation to be expected.
  • roller pins When standard roller chains are used, the roller pins should not protrude beyond the pin-link plates to a degree causing chain interlocking preventing the individual free travel of adjacent chains. Obviously the rollers should have a diameter greater than their interconnecting plates; if a nonstandard construction is used, it should be kept in mind that the rollers must be linked together so the rollers can perform their anti-friction function. In any event, chain interference can be prevented in the case of the present invention by the use of thin strips of steel, such as 1 mm. thick, extending between the chains in vertical planes and with their ends anchored at the entering end of the pressing zone.
  • roller link plates may be modified either by making them with transversely offset portions or by modifying their normal overlapping relationship, permitting the use of rollers of differing lengths having overlapping travel paths. Although such arrangements use longer rollers, their individual lengths should be kept within the limits previously described.
  • FIG. I is a side elevation of a continuous press embodying the invention.
  • FIG. 2 is a longitudinal vertical section of that press shown very schematically
  • FIG. 3 is a cross section of the press
  • FIG. 4 is a vertical cross section showing only a small portion of an upper press platen with the roller chains transmitting its force to the steel strip conveyor belts;
  • FIG. 5 is the same as FIG. 4 but shows the modification of divider steel strips separating adjacent chains
  • FIG. 6 is a vertical longitudinal section of the entering end portion of an upper platen, showing the ends of the chain loops
  • FIG. 7 and 8 are like FIGS. 5 and 6, respectively, but show modifications
  • FIG. 9 entirely schematically suggests the transversely offset chain plates with the rollers of differing lengths to provide overlapping roller paths
  • FIGS. 10 and 11 each partly sectioned, suggest how the rollers may be interfastened by differently overlapped link plates to permit the use of rollers of differing lengths to provide overlapping rolling paths.
  • FIG. 1 shows the upper and lower endless conveyor belt loops I and 2 respectively, which form opposed, substantially linear spans defining the pressing zone embraced by the bracket 3.
  • These belts are made of thin strip steel having a thickness of about 1 to 1.5 mm. and are flexible both longitudinally and transversely.
  • the upper belt I is looped around rotative drums 4 and 5, the drum 4 being fixed against lateral motion by being journaled in stationary pedestals 6; the drum 5 being capable of lateral motion by being journaled in swinging arms 7 provided with suitable swinging means 8 which provide for the application of proper tension to this upper belt.
  • the lower belt 2 at one end loops around a rotative drum 9 which is also fixed against lateral motion by being journaled in stationary pedestals 10, the other end of this lower loop passing around a rotative drum 11 journaled in sliding mountings l2 pulled by suitable actuating means 13 so that the tension of the lower belt loops may be properly attained.
  • the work W enters at the right-hand end of the press, in FIG. 1, and comes out the left-hand end with a reduced thickness, assuming wood-chip board or the like is being made;
  • the working spans of the two belts in the zone 3 are pressed together by press platens l4 and 15, the lower platen 14 being held against downward motion by transverse l-beams 16 supported by base members 17 which extend longitudinally for the length of the press.
  • the upper platen is is supported by transverse I-beams 18 which can be pulled downwardly by suitable actuators 19 which may be either of the motorized mechanical screw-t7pe or hydraulically actuated.
  • suitable actuators 19 which may be either of the motorized mechanical screw-t7pe or hydraulically actuated.
  • the platens 14 and 15 each extend for the full length of the zone 3 as one-piece constructions, excepting that, as suggested in FIG. 2, the upper one may be in two-sections to define a converging entrance zone for the work so that the latter can receive a gradually increasing pressure as it initially enters the press.
  • the beams 16 and 18 are shown as being relatively massive and, therefore, very resistant to beam stress, it is still possible for them to deflect slightly under the loading applied by the actuators 19. Should this deflection be troublesome, hollow cushions may be used between the beams and the platens, these cushions extending for the full length of the beams with which they are used and being made of flexible sheet metal, for example, and filled with fluid under pressure sufficient to carry the loading to which the beams are subjected. With such an arrangement beam deflection is not transmitted to the platens. In schematic FIG. 2 such cushions are indicated at 21. They may be used between any of the beams or all of the beams whenever needed to obtain a uniform loading throughout the widths of the platens.
  • roller chain loops providing the anti-friction means between these platens and the steel strip conveyor belt spans throughout the pressing zone 3, are generallyindicated in FIG. 2, the roller chains 22 extending between the lower belt 2 and the lower platen l4 and being individually looped by individual looping sprocket wheels 23 appropriately positioned and which are unpowered and rotatively free from one another. It can be seen that these roller chain loops 22 encircle both the lower platen 14 and its supporting beams 16.
  • FIGS. 4 through 6 the chain loops are shown as they appear with their spans running between the upper platen l8 and the upper flexible belt loop 1.
  • the above-mentioned special roller chain loop arrangement is not used in this instance, the chains entering the spanning length via semi-circular guiding surfaces 25 keyed to the ends of the platen 15 and looping in the manner of the lower chain loops. Inverting these FIGS. 4 through 6 provides a fairly clear representation of the lower platen and its anti-friction means.
  • each chain comprises inside link plates 26 between which steel rollers 27 are journaled on pins 28 passed through these plates, and
  • the outside plates have countersunk holes in which the ends of the pins are flared to provide the outside plates with smooth-flat plane surfaces beyond which the pin ends do not project.
  • the rollers 27 are 12.77 mm. in diameter, as previously mentioned, so it can be seen that FIGS. 4 through 6 are substantially full scale or 1:1 drawings. It can also be seen that the rollers are not substantially longer than their diameters.
  • each chain is entirely individually free to travel at any velocity it may acquire independently with respect to the others and, of course, with respect to the steel strip belt spans.
  • the chains are held transversely packed together and substantially intercontacting by end guides 30 fixed to the platens; because the chains outside plates 29 are smooth the chains can slide relative to each other when necessary.
  • the rollers 27 are all individually very short as previously noted. Because the chains are capable of random movement relative to each other, their various rollers are substantially incapable of becoming transversely aligned to any great extent.
  • the velocities of the various chains in the affected areas can change individually so that no roller horizontal flexing, twisting or other strain can be involved, only the press force being carried.
  • Localized belt stretching is due to the thinness of the steel strip belts which is in the area of from I to 1.5 mm. in thickness, and the driving tension on the belts.
  • the pressing surfaces 31 of the illustrated platens are flat plane surfaces free from any necessity for precision machined channels or rolling element races.
  • the platen faces may be finished by inexpensive machining, and although preferably finished as smoothly as possible for obvious reasons, slight imperfections are relatively immaterial.
  • FIGS. 5 and 6 show the thin metal strips 32, which may be steel of about 1 mm. in thickness, which serve to separate the great multiplicity of roller chains without substantially increasing their transverse separating distances.
  • the edges of these strips 32 must be kept from being rubbed by the traveling steel strip belts and this can be done by letting their opposite-ends project far enough beyond the platens for engagement by tensioning elements.
  • One such tensioning element is schematically shown at 33 in FIG. 6.
  • the lower roller chains 22 only the ends of these strips at the entrance end of the machine need be anchored because the motion of the tend lengthwise on opposite sides of the press to provide for inlet and outlet flows.
  • the platens are heated, the passages 34 being spaced far enough apart from each other to provide intervening areas of solid platen metal through which the pressing pressure from the transverse beams can travel safely.
  • Thermal insulation 36 is used where appropriate, such as between the platens and the manifolds 35 and between the platens and the beams.
  • roller chains 24a are of a difierent construction than described before.
  • each chain is a double width chain made from pairs of rollers 27a with the rollers in axial alignment as to each pair and journaled on common pins 28a and interconnected by links 26a, the flared or headed ends of the pins being in countersunk holes in the rollers so that the outer ends of the rollers of each pair are flat and smooth.
  • the separating strips 32 previously described are used to separate the various chains and the chains are kept transversely packed together by end guides 30 as previously described.
  • one of these strips shown at 32a is made high, or wide, enough to extend into a saw kerf 32b cut in the underside of the upper platen 15 which differs from the ones previously described principally only in that a sheet metal manifold 35a is shown instead of the much heavier one 35 illustrated before.
  • the strip 32a press fitted in the saw kerf 32b it is held upwardly so that only an immovable anchor 33a at the entrance end of the machine is needed even though in this instance the upper platen is involved.
  • wedges may be used to hold the strip 320 in the saw kerf, thus eliminating any need for precision work.
  • the sawing of such saw kerfs is a very simple operation as compared to the precision machining required to form bearing races.
  • FIGS. 7 and 8 The fundamental difference between FIGS. 7 and 8 and the constructions of the preceding FIGS., is that the semicircular guiding surface shown at 25 in FIG. 6 is made with alternately differing levels 25a and 2512, these levels being formed by grooves which start out at the same level and which as the rollers of the chains leave the steel strip belt 1, gradually diverge upwardly so that alternating roller chains arrive at or leave at different levels above the platen 15. Between the platen is and the upper beam 18 a metal plate 37 is interposed to handle these chain spans traveling at differing vertical heights.
  • This plate 37 has longitudinally extending passageways 38 and 39 which are laterally off set transversely and vertically from one another at the alternately different levels required by the vertically separated upper chain spans Therefore, the plate 37 can be and is made thick enough to provide adequate metal diagonally between the passageways 38 and 39 to safely carry the force exerted by the beams 18 and applied to the platen 15 through this plate 37, and the passageways 38 and 39 can be and are made to have greater heights then the diameters of the rollers of the chain spans so that these rollers do not have to carry the press force but can simply run loosely through their respective passageways.
  • the width of the passageways 38 and 39 should provide just about enough clearance to permit the chain roller to roll along freely in the passageways. The heat from the heated platen 15 is conducted into this plate 37 for absorption by the rollers of the roller chains traveling through this plates passageways, thus providing for greater heating efficiency.
  • shielding 38 provided with a flexible seal 38a where the strip belts enter or leave the press, and corresponding side edge seals 38b bearing on these belts.
  • the roller chains are fully enclosed and by providing the shielding 38 with a source of air under super-atmospheric pressure, the source being generally indicated at 39, contamination is prevented from entering the space enclosed around the roller chains.
  • the seals 38a and 38b need not be air-tight, providing the source 39 introduces an adequate volume of air to the shielding 38 to maintain a superatmospheric pressure surrounding the roller chains.
  • roller chains being packed transversely together. This is intended to mean that the various roller chains are arranged as physically close together in a transverse direction as is possible, considering the endwise roller spacing required by the chain links and the separating or divider strips 32 and 32a if they are used. Such interspacing is adequately small for most purposes, but in the manufacture of certain products, such as for the sintering of sheets of polytetrafluorethylene, the existence of longitudinally running impressions may be possible, considering the fact that the conveyor belts are flexible.
  • rollers 40 are longer than the rollers 41 and their relationship is reversed alternately from pair to pair of the rollers so that spaces between the rolling paths of any pair of rollers are always immediately rolled over by one of the longer rollers 40.
  • roller chains of FIG. 9 may be transversely packed together with their respective roller ends interengaging without any substantial danger of the chains interlocking with each other to destroy their individual ability to accelerate and decelerate relative to each other.
  • FIG. 10 A further form of such chain construction is shown in FIG. 10 in the form of the chain having strands of straight links 44.
  • These links in the upper strand however are not aligned in one lane parallel to the direction of advance but are offset, following one another, toward the same side.
  • the link 44a in FIG. 10 is offset upward relatively to the link 44.
  • the link 44b is again offset upward relatively to the link 44a.
  • the link 440 however is offset downward relatively to the link 44b, and is followed by four additional links each offset downward, as far as link 44d, after which an upward offsetting toward the right occurs.
  • the complete strand of links thus runs in a zig-zag inside the chain 80, so that the gap left between any two rollers is rolled over by the following rollers.
  • the other or lower strand of links 82 has links offset in the opposite direction relatively to the central plane of the chain.
  • Each element of the chain therefore consists of three rollers which change periodically in width, or length, and which taken all together make a single roller chain with parallel smooth surfaced delimiting faces.
  • FIGS. 9 to 11 are approximately full scale representations and it can be seen that thechains widths are very small as compared to the overall widths of the conveyor belts and their pressing platens, the latter of which may well be in the area of one to several meters in extent. If the widths of the individual chains were to be increased so extensively that only a few of the chains would be required transversely, the principles of the present invention would not be involved.
  • a fundamental concept of the present invention is the provision of unpowered roller chains each free to increase or decrease in velocity independently of the others and with the widths of the individual chains, or the lengths of their rollers, extremely small as compared to the overall transverse width of the platen and of the transversely and longitudinally flexible conveyor belts, so that a very great number of transversely packed chains are required to transversely fill the widths of these two elements of which one must move relative to the other under pressure.
  • Transversely localized and longitudinal stretching or other deformation of the flexible conveyor belts can only result in acceleration or deceleration of the individual roller chains, the rollers of which are too short individually to span such localized disturbances. Therefore, the rollers receive neither horizontal flexure not skewing strains to any extent capable of affecting their intended operation.
  • An improved continuous press including endless loops formed by longitudinally and transversely flexible conveyor belts which form opposed, substantially linear spans defining a pressing zone, means for rotatively driving at least one of said loops to drive said spans in the same direction, press platens applying pressure through said traveling spans to work carried therebetween, and anti-friction means interposed between said platens and said spans; wherein the improvement comprises said anti-friction means being formed by a multiplicity of endless loops of rotatively unpowered roller chains forming a bed interposed between said platens and said belt spans, said roller chain spans being trans-- versely packed together but each chain being individually free to travel independently with respect to the others and said belt spans.
  • rollers of said roller chains are in sets of two or more axially aligned rollers rotatively mounted on a common pin and linking plates located between the rollers of said sets interconnect the sets, the transverse width of the sets being less than can span localized deformations of said conveyor belts.
  • roller chains when free from said pressing zone are looped at differing levels around one of the platens and a plate has passages at corresponding different levels through which the chains travel and which is positioned against said one of the platens to transmit pressing force therethrough.
  • roller chains have transversely offset rollers of different lengths providing overlapping rolling paths.
  • rollers of said sets are of difl'ering lengths providing overlapping rolling paths.
