Abstract

The apparatus used for applying the process comprises a pair of reels (1, 2) for rolling up/unrolling a belt (8) bearing a layer of a bulk material. A roller which is mobile perpendicularly to the section of belt extending between the two reels can force the belt along a looped trajectory (9), at the end of which, around the roller (3), the product to be unloaded leaves the belt under the effect of gravity at the time of unwinding of the reel (1), and on the upper length (9a) of which loading of the product can be carried out when the belt is wound onto the reel (1). <IMAGE>

Description

L'invention concerne un dispositif de chargement et déchargement d'un produit en vrac sur une bobine de traitement de ce produit, selon le préambule de la revendication 1.The invention relates to a device for loading and unloading a bulk product on a reel for processing this product, according to the preamble of claim 1.

Certains traitements de produit en vrac, notamment la filtration ou la séparation des phases qui le constituent, consistent à répartir ce produit en couches relativement minces sur un support et à traiter ces couches (application d'une pression d'essorage, lavage ....).Certain treatments of bulk product, in particular filtration or separation of the phases which constitute it, consist in distributing this product in relatively thin layers on a support and in treating these layers (application of a spin pressure, washing ... .).

Dans le cas particulier du pressage d'une pulpe pour en exprimer le jus, on connaît une technique qui consiste à enrouler en couche mince la pulpe autour d'une bobine, et à soumettre cet enroulement à une compression radiale. la pulpe est supportée par une toile que l'on enroule autour d'un noyau de bobine, qui est placée dans une enceinte de pressage ; le jus extrait, on déroule la bobine pour débarrasser la toile du déchet et la recharger avec de la pulpe à presser. Cette technique est illustrée par le document EP 0 125 982.In the particular case of pressing a pulp to express the juice, a technique is known which consists of winding the pulp in a thin layer around a coil, and subjecting this winding to radial compression. the pulp is supported by a canvas which is wrapped around a coil core, which is placed in a pressing enclosure; the juice extracted, the reel is unwound to rid the canvas of the waste and reload it with pressing pulp. This technique is illustrated by document EP 0 125 982.

Pour procéder à ces opérations de chargement et déchargement du produit à traiter, l'invention entend proposer un dispositif plus simple que celui décrit dans ce document grâce auquel, avec moins de composants, on peut desservir une pluralité de portes de traitement et ce de manière automatisable.To carry out these loading and unloading operations of the product to be treated, the invention intends to propose a simpler device than that described in this document thanks to which, with fewer components, it is possible to serve a plurality of processing doors and this so automatable.

A cet effet, le dispositif selon l'invention est conforme à la revendication 1.To this end, the device according to the invention is in accordance with claim 1.

Dans un mode de réalisation de ce dispositif, les moyens de déplacement du rouleau de renvoi sont constitués par deux organes d'entraînement souples sans fin et parallèles entre eux auxquels sont attelées les extrémités du rouleau, une table de soutien du brin supérieur de la toile étant disposée entre lesdits organes, derrière le rouleau par rapport à son sens de déplacement de sa première vers sa deuxième position.In one embodiment of this device, the means for moving the deflection roller are constituted by two endless flexible drive members which are parallel to each other and to which the ends of the roller are coupled, a support table for the upper strand of the fabric being disposed between said members, behind the roller relative to its direction of movement from its first to its second position.

Il existe plusieurs variantes de ce mode de réalisation. Dans une première variante, le support motorisé de la bobine principale appartient à un bâti fixe de la machine de pressage et peut déplacer la bobine parallèlement à son axe depuis une position de traitement par exemple à l'intérieur d'une enceinte, jusqu'à une position de chargement-déchargement, à l'extérieur de cette enceinte.There are several variants of this embodiment. In a first variant, the motorized support of the main coil belongs to a fixed frame of the pressing machine and can move the coil parallel to its axis from a treatment position, for example inside an enclosure, up to a loading-unloading position, outside this enclosure.

La bobine secondaire peut être portée par un support secondaire situé sous la bobine principale en position de chargement-déchargement. Le support secondaire peut également supporter le rouleau de renvoi et le mécanisme qui permet de le déplacer pour former la boucle susdite. Dans le cas où il existe plusieurs postes de traitement à desservir, le support secondaire peut être mobile le long d'un chemin de guidage s'étendant devant chacun de ces postes, jusqu'à un poste de chargement qui peut être constitué par une trémie d'amenée du produit.The secondary coil can be carried by a secondary support located under the main coil in position loading-unloading. The secondary support can also support the deflection roller and the mechanism which makes it possible to move it to form the above-mentioned loop. In the case where there are several treatment stations to be served, the secondary support can be movable along a guide path extending in front of each of these stations, up to a loading station which can be constituted by a hopper the product.

Dans une autre variante, la ou les bobines secondaires sont fixes, sous la ou les bobines principales et le rouleau de renvoi est déplaçable le long d'un guide fixe sensiblement horizontal s'étendant dans un plan intermédiaire entre les bobines principales et les bobines secondaires.In another variant, the secondary coil or coils are fixed, under the main coil or coils and the deflection roller is movable along a substantially horizontal fixed guide extending in an intermediate plane between the main coils and the secondary coils .

Dans une variante supplémentaire, le support des bobines secondaires et du rouleau de renvoi constitue également le support motorisé des bobines principales qui sont extraites de l'enceinte de traitement et peuvent ainsi être conduites à un poste de déchargement et un poste de chargement.In an additional variant, the support for the secondary coils and the deflection roller also constitutes the motorized support for the main coils which are extracted from the treatment enclosure and can thus be brought to an unloading station and a loading station.

La ou les bobines secondaires présentent de manière avantageuse une fente dans leur moyeu pour la fixation amovible de l'extrémité libre lestée de la toile.The secondary coil (s) advantageously have a slot in their hub for the removable fixing of the free weighted end of the fabric.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif qui permettra d'en dégager les avantages et d'autres caractéristiques.The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will make it possible to identify the advantages and other characteristics thereof.

En se reportant tout d'abord aux figures 1 à 7, on voit une bobine principale 1, une bobine secondaire 2 située à l'aplomb de la bobine principale, un rouleau de renvoi 3 déplaçable par des moyens d'entraînement 4 qui s'étendent dans un plan sensiblement horizontal entre les bobines 1 et 2. Ces figures montrent aussi une trémie de chargement 5 pour un produit P à traiter et un transporteur 6 d'évacuation du produit P′ traité, et un rouleau secondaire 7 de guidage de la toile 8 qui circule entre les deux bobines, lorsque le rouleau de renvoi 3 est dans sa position active. Les différents supports de ces organes ne sont pas représentés aux figures. Ils apparaîtront en regard des figures suivantes. Les bobines 1 et 2 sont accouplées à des organes d'entraînement et de contrôle de leur rotation permettant l'enroulage et le déroulage de la toile avec des possibilités de réglage de sa tension.Referring first to Figures 1 to 7, we see a main coil 1, a secondary coil 2 located directly above the main coil, a deflection roller 3 movable by drive means 4 which extend in a substantially horizontal plane between the coils 1 and 2. These figures also show a loading hopper 5 for a product P to be treated and a conveyor 6 for discharging the treated product P ′, and a secondary roller 7 for guiding the fabric 8 which flows between the two coils, when the deflection roller 3 is in its active position. The various supports of these members are not shown in the figures. They will appear next to the following figures. The coils 1 and 2 are coupled to drive and rotation control members allowing the winding and unwinding of the fabric with possibilities of adjusting its tension.

La figure 1 représente le dispositif à l'état initial, c'est-à-dire au moment où le chargement de la bobine 1 va commencer. La toile 8 est entièrement déroulée de la bobine 1 sur laquelle elle est fixée par l'une de ses extrémités. Le rouleau de renvoi 3 est dans sa position active dans laquelle il force la toile 8 à former entre les bobines une boucle 9 dont le brin supérieur 9a est sensiblement horizontal. Le déplacement du rouleau 3 s'effectue le long du brin supérieur 4a de l'organe d'actionnement 4 qui est ici constitué par deux chaînes sans fin parallèles auxquelles est fixé le rouleau 3. Ces chaînes portent derrière le rouleau 3 une pluralité de lattes 10 qui forment une table sur laquelle peut reposer le brin 9a de la toile 8, notamment sous l'action du rouleau de renvoi secondaire 7.Figure 1 shows the device in the initial state, that is to say when the loading of the coil 1 will begin. The fabric 8 is fully unwound from the reel 1 on which it is fixed by one of its ends. The deflection roller 3 is in its active position in which it forces the fabric 8 to form between the coils a loop 9 whose upper strand 9 a is substantially horizontal. The movement of the roller 3 is carried along the upper run 4a of the actuator 4 which is constituted by two parallel endless chains to which is fixed the roller 3. These chains are behind the roller 3 a plurality of slats 10 which form a table on which the strand 9 a of the cloth 8 can rest, in particular under the action of the secondary deflection roller 7.

La toile 8 est donc déformée en boucle 9 et enroulée sur la bobine secondaire 2. La boucle 9 s'étend jusque sous la trémie 5 ou du moins jusque sous son ouverture de distribution (qui peut comporter un tapis d'entraînement du produit).The fabric 8 is therefore deformed into a loop 9 and wound on the secondary coil 2. The loop 9 extends as far as under the hopper 5 or at least as far as its distribution opening (which may include a product drive belt).

La bobine 1 est entraînée en rotation pour enrouler la toile avec le produit P qui s'y dépose. Cette phase est représentée en figure 2.The coil 1 is rotated to wind the fabric with the product P which is deposited there. This phase is shown in Figure 2.

Sur la figure 3, la toile 8 est presque totalement enroulée autour de la bobine 1. La distribution du produit P par la trémie 5 est arrêtée et le rouleau 3 est déplacé vers la droite de la figure pour effacer la boucle 9.In FIG. 3, the fabric 8 is almost completely wound around the reel 1. The distribution of the product P by the hopper 5 is stopped and the roller 3 is moved to the right of the figure to erase the loop 9.

La figure 4 montre la fin de l'enroulement de la toile sur la bobine 1 et la libération de l'attache de la toile à la bobine secondaire 2. Le rouleau 3 est dans une position 3′ escamotée.FIG. 4 shows the end of the winding of the fabric on the spool 1 and the release of the attachment of the fabric to the secondary spool 2. The roller 3 is in a retracted position 3 ′.

Entre la figure 4 et la figure 5 il s'est produit un traitement de la toile chargée enroulée sur la bobine 1, cette bobine ayant été déplacée depuis ce poste d'enroulement déroulement jusqu à un poste de traitement, puis ramenée à sa position d'origine. En actionnant sa motorisation, on commence le déroulement de la toile 8 dont l'extrémité 8a, de préférence lestée, vient se loger dans une fente 2a de la bobine 2 prévue à cet effet. L'extrémité de la toile est donc immobilisée dans la bobine 2.Between FIG. 4 and FIG. 5, there has been a treatment of the loaded fabric wound on the spool 1, this spool having been moved from this unwinding winding station to a treatment station, then brought back to its position d 'origin. By actuating its motorization, one begins the unwinding of the fabric 8 whose end 8 a , preferably ballasted, is housed in a slot 2 a of the coil 2 provided for this purpose. The end of the fabric is therefore immobilized in the coil 2.

La figure 6 illustre le déplacement du rouleau 3, perpendiculairement au pan de toile entre les bobines 1 et 2, et la formation qui en résulte de la boucle 9, la toile étant déviée par le rouleau 3.FIG. 6 illustrates the displacement of the roller 3, perpendicular to the section of fabric between the coils 1 and 2, and the resulting formation of the loop 9, the fabric being deflected by the roller 3.

La figure 7 enfin montre le dévidage de la toile qui s'enroule sur la bobine 2 entraînée en rotation. Le produit P′ résiduel situé sur cette toile s'en détache au passage du rouleau 3 et tombe sur le tapis transporteur 6 d'évacuation. La toile peut, entre le rouleau 3 et la bobine 2 subir un traitement de nettoyage approprié.Figure 7 finally shows the unwinding of the fabric which is wound on the spool 2 driven in rotation. The residual product P ′ located on this fabric is detached from it when the roller 3 passes and falls onto the conveyor belt 6 for evacuation. The fabric can, between the roller 3 and the spool 2 undergo an appropriate cleaning treatment.

Sur ces figures on voit également des bobines 1a et 1b dessinées en traits interrompus, qui illustrent le fait que la machine de traitement (par exemple pressage) du produit peut comporter plusieurs postes. Le dispositif de chargement-déchargement schématiquement illustré peut desservir chacun de ces postes si les temps de cycle le permettent et si la bobine 2 peut être amenée à l'aplomb de chacune des bobines 1, 1a et 1b. Il suffit en effet que la course du rouleau 3, au moyen de son dispositif d'entraînement 4, soit suffisante pour pouvoir intercepter chacune des bandes issues des bobines et former avec chacune d'elles une boucle 9.In these figures we also see coils 1 a and 1 b drawn in dashed lines, which illustrate the fact that the product processing machine (for example pressing) can have several stations. The schematically illustrated loading-unloading device can serve each of these stations if the cycle times allow it and if the coil 2 can be brought in line with each of the coils 1, 1 a and 1 b . It suffices in fact that the stroke of the roller 3, by means of its driving device 4, is sufficient to be able to intercept each of the strips coming from the reels and to form a loop 9 with each of them.

La figure 8 montre schématiquement que la bobine 2 peut être solidaire d'un chariot 11 qui se déplace de l'une à l'autre des bobines 1, 1a, 1b. Ce chariot 11 peut également porter le rouleau de renvoi secondaire 7.FIG. 8 schematically shows that the coil 2 can be secured to a carriage 11 which moves from one to the other of the coils 1, 1 a , 1 b . This carriage 11 can also carry the secondary deflection roller 7.

La figure 9 est un schéma dans lequel le chariot 12 possède en plus les moyens pour prendre en charge chacune des bobines 1, 1a, 1b lorsqu'elles sortent du poste de traitement pour les véhiculer vers un poste 13 de déchargement et sous un poste 14 de chargement. Dans ce cas, le rouleau 3 et son mécanisme d'entraînement 4 sont également portés par le chariot 12. Le mécanisme 4 peut dans cette variante de réalisation affecter une forme autre que celle de chaînes sans fin d'entraînement. Il peut notamment s'agir de verins poussant le rouleau 3, compte tenu du fait que la course de ce rouleau est beaucoup plus limitée que dans les cas précédents.FIG. 9 is a diagram in which the carriage 12 additionally has the means for taking charge of each of the coils 1, 1 a , 1 b when they leave the processing station to transport them to an unloading station 13 and under a loading station 14. In this case, the roller 3 and its drive mechanism 4 are also carried by the carriage 12. The mechanism 4 can, in this variant embodiment, have a shape other than that of endless drive chains. It can in particular be cylinders pushing the roller 3, taking into account the fact that the travel of this roller is much more limited than in the previous cases.

Sur la figure 10 on voit une disposition dans laquelle chaque bobine 1, 1a, 1b est associée à une bobine fixe 2, 2a, 2b et à des rouleaux secondaires de renvoi 7, 7a 7b également fixes. Le rouleau 3 est entraîné, ainsi que la table 10 par une paire de chaînes ou câbles sans fin 4. Cette figure montre le chargement ou le déchargement de la bobine 1a tandis que les deux autres bobines subissent des phases de traitement (par exemple un pressage radial dans des enceintes 15).In Figure 10 we see an arrangement in which each coil 1, 1 a , 1 b is associated with a fixed coil 2, 2 a , 2 b and secondary return rollers 7, 7 a 7 b also fixed. The roller 3 is driven, as the table 10 by a pair of chains or endless cables 4. This figure shows the loading or unloading of the coil 1 a while the other two coils undergo processing phases (for example a radial pressing in chambers 15).

Le support motorisé des bobines 1, 1a, 1b, comporte un bras horizontal parallèle à l'axe de chaque enceinte 15 et la traversant ce qui permet de déplacer chaque bobine de l'intérieur vers l'extérieur de l'enceinte et inversement et, en position extérieure, de la faire tourner autour de son axe.The motorized support of the coils 1, 1 a , 1 b , comprises a horizontal arm parallel to the axis of each enclosure 15 and passing through it which makes it possible to move each coil from the inside to the outside of the enclosure and vice versa and, in the external position, to rotate it around its axis.

La figure 11 montre par une vue de détail que chaque bobine 2 possède une fente 16 dans laquelle l'extrémité 8a, lestée, est logée pour être emprisonnée par un volet de rabattement 17 ou tout autre dispositif adéquat lorsqu'il s'agit de dérouler la toile de la bobine 1, et pour être libérée à la fin de l'enroulement de la toile sur la bobine 1.11 shows a detailed view of each coil 2 has a slot 16 in which the end 8a, ballasted, is accommodated to be trapped by a folding flap 17 or any other suitable device in the case of unwind the fabric from the spool 1, and to be released at the end of the winding of the canvas on the spool 1.

L'une des applications intéressantes de l'invention est le chargement et le déchargement des bobines d'une machine de pressage d'un produit (par exemple une pulpe) pour en extraire la phase liquide. L'invention s'applique également à la manutention d'un produit d'un poste de stockage à un poste de traitement quelconque et de ce poste à un poste d'évacuation, dans la mesure où le traitement du produit implique son enroulement en couches autour d'un noyau cylindrique.One of the interesting applications of the invention is the loading and unloading of the coils of a machine for pressing a product (for example a pulp) in order to extract the liquid phase therefrom. The invention also applies to the handling of a product from a storage station to any treatment station and from this station to an evacuation station, insofar as the treatment of the product involves its winding in layers around a cylindrical core.
