figure 12 is section XII-XII offigure 9 . - With reference to the figures of the drawings, 1 denotes in its entirety a machine for manufacturing pressed loose material products (possibly with the use of a glue). The loose material could comprise, for example, wood chips. The material to be pressed and/or the glue are heated by a hot fluid (for example water vapour) in order to activate in a short time the reactions which contribute to transforming the loose material into a compact block by effect of pressing. The pieces obtained in the illustrated example are small blocks, for example rectangular or cylindrical, destined for example to be used as components in manufacturing pallets: in this case the pieces obtained constitute spacer elements, located below the load plane of the pallet, the spacer elements going to create the spaces below the plane for the insertion of forklift truck forks.
- The
machine 1 comprises amould 2 in which a plurality of through-cavities 3 are afforded, one by the side of another, longitudinally extended and parallel to each other. In the illustrated case the mould comprises a single parallelepiped block of considerable width and provided withcavities 3 arranged in a special order. - The cavity axis is vertical.
- A first
pressor element 4 is axially mobile on command according to an axis which is parallel to the vertical axis of thecavity 3. The firstpressor element 4 can assume an active position (figure 4 andfigure 3 in a broken line) in which it is lowered, and presents a flat lower side which is in contact with an upper face, also flat and horizontal, of themould 2. The upper face of themould 2 is perpendicular to the axis of thecavity 3. In the active position the firstpressor element 4 closes the upper end of thecavity 3. - The first
pressor element 4 can also assume an inactive position (represented infigures 1 ,5 and3 in a continuous line), in which the lower side thereof is distanced from the upper face of themould 2. - The machine comprises a plurality of second
pressor elements 5 which face the firstpressor element 4 and collaborate there-with. The secondpressor elements 5 extend in length in a parallel direction to the vertical cavities arranged one beside another. Each of the secondpressor elements 5 is axially mobile on command internally of arespective cavity 3 of the mould and can assume a lower first position (figures 1 and3 ) in which the cavities are filled with material to be pressed, and in which the lower end of therespective cavities 3 is closed, i.e. the end situated at the opposite end of the mould from the above-cited upper face. In the lower first position each of the secondpressor elements 5 is relatively distant from the upper face of the mould and inferiorly delimits the cavity to be filled with the material to be pressed. The lower position of the secondpressor elements 5 with respect to the upper face of themould 2 determines the size of the filling cavity and can be chosen on the basis of the final density of the product to be obtained. Eachfilling cavity 3 extends in a vertical direction. The material to be pressed can be constituted by solid loose material (for example wood chips) or by an agglomerating substance (for example an adhesive resin), or by a mixture of the two. The secondpressor elements 5 are supported by and are solidly constrained to a horizontallower plate 6 which is perpendicular to the secondpressor elements 5 and vertically mobile on command. - Each of the second
pressor elements 5 can assume an intermediate second position (figure 4 ) for the material pressing operation, chosen on the basis of the height or breadth of the final piece desired, in which intermediate second position the secondpressor elements 5 exhibit their upper end internally of the respective cavities and closer to the upper face of the mould. Each secondpressor element 5 can also assume an upper third position (figure 5 ) in which the pressed piece P is expelled from the mould; in this third position the upper end of the secondpressor element 5 is coplanar or very nearly so to the flat upper face of themould 2. - The machine comprises means for injecting a hot activating fluid internally of the
filling cavity 3; the activating function is generally the heat of the fluid. The hot fluid is injected internally of the mass of the material introduced into thefilling cavity 3 before and during the pressing operation, so that it can act on the material (for example the resin or the material to be pressed) in order to obtain compact and resistant pieces rapidly. The hot fluid used is, for example, water vapour. - The means for injecting the hot fluid comprise at least one feeding line 7 of hot fluid which sends the fluid towards a
manifold 8 afforded internally of thelower plate 6 supporting the second pressor elements 5 (figure 1 ). The manifold 8 s connected to a plurality of hot fluid infeedconduits 9, each of which is afforded internally of a secondpressor element 5. In the enlargement offigure 1 , the secondpressor elements 5 are only schematically represented: figures from 8 to 12 give more detailed illustrations of a secondpressor element 5. Each infeedconduit 9 superiorly terminates in a horizontally-extendedchamber 9a from which plurality of nozzles 9' depart, which nozzles 9' are also afforded internally of the secondpressor element 5. Each nozzle 9' opens into thefilling cavity 3 through one or more outlets for the fluid located at the upper end of the secondpressor element 5. Thus each filling cavity comes into contact with a plurality of upwards-facing hot fluid outlets. In the illustrated embodiment these outlets are aligned one with another. - The machine further comprises means for heating both the first
pressor element 4, themould 2 and the secondpressor elements 5. The means for heating comprise a series of separate circuits, afforded internally of the above-cited elements, in which a second hot fluid (for example heat-radiating oil) circulates. The heating facilitates the hardening of the pressed material and the activation of a glue if present. In thefigures 11 and 12 denote the delivery and return conduits of the second hot fluid, which are afforded internally of a secondpressor element 5 and are extended over almost the whole length thereof. - In each of the second
pressor elements 5 there is at least one further infeedconduit 13 for an active substance, for example paraffin, having one or more outlets 13' arranged on the lateral side of the secondpressor element 5 in alow area 14 preferably close to the upper end of the secondpressor element 5. The substance is injected from the inside of the secondpressor elements 5 towards the outside during the return run of the secondpressor elements 5, internally of thefilling cavities 3 before filling them. The substance is distributed on the internal walls of thecavities 3, forming a thin layer so that after filling and pressing the external surfaces of the pieces exhibit special characteristics which depend on the substance used (for example by using paraffin water-repellent surfaces are obtained) and which also facilitate detachment of the pieces from the mould walls. The variouslower areas 14 form, together with the internal surface of thefilling cavity 3, small chambers which spread over the whole of the transversal of thecavity 3. - The machine can be equipped with means for aspirating, of known type and not illustrated, which are preferably connected to the circuits through which the activating fluid is injected into the
filling cavity 3. These means for aspirating create a depression in the filling cavities and thus collect the vapours issued during the pressing operation. - With reference to
figures 6 and 7 , the material loading device into the mould is now described. This device comprises a commandable axiallymobile drawer 15, mobile onhorizontal guides 16 in the direction of arrows J. Thedrawer 15 can assume a first position (figure 7 and on the right infigure 6 ) in which it is in a material deposit station and receives the material destined for pressing; this station can be for example ahopper 17. The drawer can also assume a second position (on the left infigure 6 ) in which it is entirely above themould 2. Thedrawer 15 is open both above and below. One or more rotating combs (set on rollers 18) are located at the lower opening of thedrawer 15; therollers 18 can be commanded to rotate about an axis which is transversal to the drawer movement axis. Eachroller 18 bears a plurality of radial teeth thickly distributed over the external surface of theroller 18 and arranged in such a way as not to interfere with the teeth of anadjacent roller 18 during rotation. - When the
drawer 15 is in the first position, the lower opening is closed by a horizontal fixedplane 19, which in effect becomes the bottom of thedrawer 15 and prevents exit of the material from the bottom of thedrawer 15. Theplane 19 is coplanar to the mould and extends up to the mould itself. To fill themould 2, thedrawer 15 displaces axially towards themould 2, moving on the horizontal guides 16. While the lower opening of thedrawer 15 is thus closed by the fixedplane 19, up to the edge of themould 2, the material will not fall down; then, as the drawer advances onto themould 2, the material will fall, as the bottom constituted by the plane is no longer present. In the meantime the rotating combs distribute the material in thecavities 3, depositing the material uniformly up until thecavities 3 are filled. Once this point has been reached, thedrawer 15 returns and its front terminal part, equipped with a scraper, removes the excess material, thus guaranteeing optimal conditions for a homogeneous pressing of the material. The pressing operation is now described, starting from the configuration offigure 1 , in which the firstpressor element 4 is raised and in the inactive position and the secondpressor elements 5 are lowered and in the filling position. In this configuration the above-described loading device introduces the material to be pressed into the fillingcavities 3 which are closed below by the second pressor elements 5 (figure 3 ). - Subsequently the first
pressor element 4 is made to lower, in the direction of arrow F, up until it comes into the active position in which it superiorly closes the various filling cavities. At this point theplate 6 supporting the secondpressor elements 5 is raised, in the direction of arrow G into an end-pressing position (seefigure 4 ), to press the material into the fillingcavities 3. At the same time the means for injecting inject the hot fluid upwards into the mass of material. The injection stage can begin before the pressing phase. The hot activating fluid enters from the bottom into the mass of material contained in the cavity to activate the reactions contributing to transforming the loose material into a compact and coherent block after pressing. - Once the compacting stage has been completed, comprising both the pressing and the activation of the glue if any, the first
pressor element 4 is raised in the direction of arrow H, after which the plate is also raised (arrow K) to bring the secondpressor elements 5 into the expelling position (figure 5 ). The pressed pieces P, after expulsion from the cavities in an upwards direction, can be easily removed from the mould. - The hot fluid can be injected internally of the filling
cavities 3 from above, through the firstpressor element 4, either alternatively or in concert with the means for injecting which operate from the side of the secondpressor elements 5. In this case second means for injecting the hot fluid are provided, which comprise asupply line 10 which conveys the fluid towards a manifold afforded internally of the firstpressor element 4. The manifold is connected to a plurality of nozzles which terminate with downwards-facing outlets for the fluid, predisposed on the flat lower side of the firstpressor element 4, for injecting the fluid internally of the filling cavities during the material compacting stage, activating the resin or glue.
