Description

La présente invention concerne un nouveau dispositif rotatif où linéaire équipé de caisson compacteur et de goulotte accroche sac destiné à réaliser en continu les différentes opérations d'ensachage sous vide à l'aide de caissons compacteurs conformateurs et de cloches de mise sous vide utilisées pour compacifier et mettre en forme le sac de conditionnement et son contenu éventuellement dégazéThe present invention relates to a new rotary or linear device equipped with compactor box and bag-hanging chute intended to continuously carry out the various vacuum bagging operations using conforming compactor boxes and vacuum bells used to compact and shape the packaging bag and its possibly degassed contents

Ces dispositifs sont généralement utilisés pour conserver dans les meilleures conditions et le plus faible volume les matériaux en poudre, granulés ou concassés, hygroscopiques, périssables à l'air ou à l'humidité .These devices are generally used to preserve in the best conditions and the lowest volume materials in powder, granulated or crushed, hygroscopic, perishable in air or humidity.

On utilisait jusqu'à présent différents types de conditionnement sous vide qui, généralement, s'organisaient autour d'une goulotte articulée portant le sac et commandée par un jeu de vérins . Le sac , accroché à cette goulotte, était, durant l'opération d'ensachage , placé sous vide au moyen d'une pompe externe, raccordé à des orifices disposés sur les parois de la goulotte.Until now, different types of vacuum packaging have been used, which are generally organized around an articulated chute carrying the bag and controlled by a set of jacks. The bag, attached to this chute, was, during the bagging operation, placed under vacuum by means of an external pump, connected to orifices arranged on the walls of the chute.

Cette disposition servait d'une part à évacuer l'air contenu dans le sac, et d'autre part, à faciliter l'opération de compacification obtenue au moyen d'un vibreur situé sur le plancher du compacteur conformateur et sur lequel reposait le sac .This arrangement served on the one hand to evacuate the air contained in the bag, and on the other hand, to facilitate the compacification operation obtained by means of a vibrator located on the floor of the conforming compactor and on which the bag rested. .

Tous ces disposititifs étaient caractérisés par un réservoir de matériaux à conditionner, doté à sa partie inférieure, d'un manchon souple ou rigide que l'on pouvait éventuellement obturer. Le sac de conditionnement était relié à ce manchon par l'intermédiaire d'une goulot rigide ou articulée dont l'ouverture était commandée par un jeu de deux marteaux actionnés par des vérins . La partie haute du sac fixée sur la goulotte était protégée de toute pollution au moyen de barrettes d'étanchéité reliées entre elles afin de plaquer le haut du sac contre les parois externes de la goulotte.All these devices were characterized by a reservoir of materials to be packaged, provided at its lower part, with a flexible or rigid sleeve which could possibly be closed. The conditioning bag was connected to this sleeve via a rigid or articulated neck, the opening of which was controlled by a set of two hammers actuated by jacks. The upper part of the bag fixed on the chute was protected from any pollution by means of sealing strips connected to each other in order to press the top of the bag against the external walls of the chute.

Après les opérations de remplissage et de désaération obtenues au moyen d'un circuit de pompage annexé, on compacifiait le produit au moyen d'un vibreur logé sous le plateau portant le sac.After the filling and deaeration operations obtained by means of an annexed pumping circuit, the product was compacted by means of a vibrator housed under the tray carrying the bag.

Le sac, le vibreur et le plateau étaient logés à l'intérieur d'un caisson rigide installé à J'intérieur de deux coquilles montées sur une glissière de façon à s'ouvrir à la manière d'une machoire, et se refermant sur la partie inférieure de la goulotte .The bag, the vibrator and the tray were housed inside a rigid box installed inside two shells mounted on a slide so as to open in the manner of a jaw, and closing on the lower part of the chute.

Sur la partie supérieure du caisson, on trouvait deux barres parallèles commandées par un jeu de vérins et de ressorts qui pouvaient pincer sous deux pressions différentes la partie haute du sac située sous la goulotte, suivant que l'on pratiquait un conditionnement sous vide ou une simple désaération de matériaux poudreux susceptibles de provoquer une obturation des circuits.On the upper part of the box, there were two parallel bars controlled by a set of jacks and springs which could pinch the upper part of the bag located under the chute under two different pressures, depending on whether vacuum packaging or simple deaeration of powdery materials likely to cause blockage of the circuits.

Lors de certaines opérations d'ensachage , le caisson conformateur se refermait sur le sac au niveau de la goulotte, puis était rendu étanche au moyen d'un joint placé à demeure entre les deux coquilles. Le caisson était mis ensuite en dépression par l'intermédiaire d'un autre dispositif de pompage extérieur, afin d'accélérer l'opération de remplissage du sac, la compacification du produit contenu, sa mise en forme, augmentant ainsi la cadence de conditionnement .During certain bagging operations, the shaping box closed on the bag at the level of the chute, then was sealed using a seal placed permanently between the two shells. The box was then placed under vacuum via another external pumping device, in order to accelerate the bag filling operation, the compacification of the product contained, its shaping, thus increasing the rate of packaging.

D'autres dispositifs utilisaient des techniques d'ensachage plus rudimentaires, réalisées au moyen d'un carrousel destiné à distribuer les matériaux à conditionner dans différents sacs, de façon continue, par l'intermédiaire d'une goulotte et d'une trémie .Other devices used more rudimentary bagging techniques, carried out by means of a carousel intended to distribute the materials to be packaged in different bags, continuously, via a chute and a hopper.

Tous ces types de dispositifs présentaient de nombreux avantages et notamment :

  • - un encombrement minimum
  • - un coût modéré de l'installation d'ensachage
  • - une bonne qualité de conditionnement.
All these types of devices had many advantages, including:
  • - minimum dimensions
  • - a moderate cost of the bagging installation
  • - good packaging quality.

Par contre, cette technologie présentait de nombreux inconvénients, notamment lors de l'utilisation de la goulotte articulée :

  • - une mise en oeuvre délicate, voir difficile, nécéssitant une adaptation particulière pour chaque produit,
  • - un encrassement rapide du circuit de désaération et d'écoulement des matériaux à conditionner,
  • - un fonctionnement discontinu,
  • - un faible rendement avec une cadence limite,
  • - dans le cas de l'utilisation du dispositif avec carrousel rotatif, il était difficile d'opérer une désaération du contenu du sac et sa compacification simultannément ,
  • - on créait en outre une pollution de l'atmosphère lorsqu'on utilisait des matériaux poudreux générant un aérosol .
On the other hand, this technology had many drawbacks, in particular when using the articulated chute:
  • - a delicate implementation, even difficult, requiring a specific adaptation for each product,
  • - rapid fouling of the deaeration and flow circuit of the materials to be packaged,
  • - discontinuous operation,
  • - low efficiency with a limited rate,
  • - in the case of using the device with rotary carousel, it was difficult to deaerate the contents of the bag and its compacification simultaneously,
  • - We also created air pollution when using powdery materials generating an aerosol.

C'est pour pallier à ces inconvénients qu'il est proposé ici un nouveau dispositif d'ensachage sous vide rotatif équipé de caissons compacteurs conformateurs et de goulottes accroche-sacsIt is to overcome these drawbacks that a new rotary vacuum bagging device is proposed here equipped with conforming compactor boxes and bag-hanging chutes.

Ce nouveau dispositif d'ensachage sous vide rotatif où linéaire avec caissons compacteurs conformateurs est caractérisé par un plateau mobile comprenant 4 postes de travail, équipé de caissons compacteurs conformateurs avec porte latérale, d'un conformateur vibrant, de glissières et de joints, de goulotte métallique, d'accroche sacs, de barrettes d'étanchéité mobiles, d'une cloche de mise sous vide mobile, raccordée à une pompe, des tendeurs nettoyeurs du haut du sac, des barres de serrage du haut du sac, d'un dispositif de soudure .This new rotary or linear vacuum bagging device with conforming compactor boxes is characterized by a mobile platform comprising 4 work stations, equipped with conforming compactor boxes with side door, a vibrating conformator, slides and gaskets, chute metal, bag hanger, mobile sealing bars, a mobile vacuum hood, connected to a pump, tensioners cleaning the top of the bag, clamping bars of the top of the bag, a device Welding .

La présente invention ainsi caractérisée présente de nombreux avantages et notamment :

  • - un rendement optimal
  • - une mise en oeuvre facile
  • - une grande solidité pour un fonctionnement fiable
  • - une parfaite étanchéité vis à vis de l'atmosphère ambiante

Suivant une caractéristique importante de l'invention, on a représenté à la figure 1 de la planche I/11 l'ensemble du dispositif d'ensachage sous vide rotatif équipé de caisson compacteur conformateur et de goulotte accroche sac. La tour du carrousel (17) est montée sur un plateau tournant (16) animé dans son mouvement par un moteur non représenté sur ce dessin . Sur ce carrousel (17) on trouve 4 postes de travail doté chacun d'un caisson compacteur conformateur . Chaque caisson rigide (1) est doté d'une porte latérale (2) contenant un compacteur conformateur (3). Chaque caisson est coiffé par une goulotte (4) munie d'accrôche sac (5) et de barrettes d'étanchéité (6) . Le sac (21) placé dans le caisson se déplace sur les glissières (18) solidaires du plateau (16) pour venir, en fin d'opération, se positionner sous une cloche de mise sous vide (7) pourvue de tendeurs (8) nettoyeurs du haut du sac, et d'un jeu de barres de serrage (9) exerçant une forte pression pendant la soudure du sac, obtenue par une autre barre de serrage (10). Une tubulure (11) permet de relier la cloche (7) à une pompe d'aspiration (12) située à l'intérieur de la tour du carrousel. L'étanchéité du caisson est obtenue au moyen d'une porte (2) plaquée sur le joint (13) solidaire du caisson.According to an important characteristic of the invention, there is shown in FIG. 1 of the board I / 11 the entire bagging device under rotary vacuum equipped with a shaping compactor box and a bag hanger. The carousel tower (17) is mounted on a turntable (16) driven in its movement by a motor not shown in this drawing. On this carousel (17) there are 4 work stations each with a conforming compactor box. Each rigid box (1) has a side door (2) containing a shaping compactor (3). Each box is capped by a chute (4) provided with a bag hook (5) and sealing bars (6). The bag (21) placed in the box moves on the slides (18) integral with the plate (16) to come, at the end of the operation, to be positioned under a vacuum bell (7) provided with tensioners (8) cleaners at the top of the bag, and a set of clamping bars (9) exerting a strong pressure during the sealing of the bag, obtained by another clamping bar (10). Tubing (11) allows the bell (7) to be connected to a suction pump (12) located inside the carousel tower. The tightness of the box is obtained by means of a door (2) pressed against the seal (13) secured to the box.

L'étanchéité entre la cloche de mise sous vide mobile verticalement. sur ses glissières (20) et le caisson, est assurée par le joint (14). Les éléments permettant d'assurer les mouvements du caisson (1) , de la goulotte (4) et de la cloche de mise sous vide (7) sont des vérins pneumatiques non représentés ici.The seal between the vertically movable vacuum chamber. on its slides (20) and the box, is ensured by the seal (14). The elements ensuring the movements of the box (1), the chute (4) and the vacuum bell (7) are pneumatic cylinders not shown here.

Le sac (21) est, durant toutes les opérations, placé dans le compacteur conformateur (3) et accroché à la goulotte (4) au moyen d'accroche sac (5) . Sous ces accroche sacs, on trouve les barrettes d'étanchéité (6) qui se referment lorsque le sac est rempli.The bag (21) is, during all the operations, placed in the shaping compactor (3) and hung on the chute (4) by means of bag hook (5). Under these bag hangers, there are the sealing bars (6) which close when the bag is filled.

L'étanchéité entre le sac et la goulotte est assurée par un dispositif télescopique (22) garni d'un joint (15) à sa partie inférieure au-dessus de ce dispositif (22) un système de pesage (23) alimente en produit à conditionner le sac (21). Ce produit est acheminé par une vis sans fin (24) placée au-dessus du système de pesage (23).The seal between the bag and the chute is ensured by a telescopic device (22) provided with a seal (15) at its lower part above this device (22) a weighing system (23) supplies product to condition the bag (21). This product is conveyed by an endless screw (24) placed above the weighing system (23).

Les liaisons électriques nécessaires à l'alimentation des moteurs animant l'ensemble du dispositif dont la commande est assurée par un pupitre extérieur, sont obtenues par un joint rotatif électrique (25) dont l'une des parties est solidaire de la tour (17) tandis que la partie fixe est reliée au chassis support (26). L'alimentation en air comprimé est obtenue également par un joint rotatif classiqueThe electrical connections necessary to power the motors driving the entire device, the control of which is ensured by an external console, are obtained by an electrical rotary joint (25) one of the parts of which is integral with the tower (17) while the fixed part is connected to the support frame (26). The compressed air supply is also obtained by a conventional rotary joint

On a représenté sur la figure 2 de la planche II/11 l'ensemble du dispositif vu de dessus, afin de faire apparaître les 4 postes de travail qui fonctionnent simultannément.There is shown in Figure 2 of Plate II / 11 the entire device seen from above, in order to show the 4 workstations which operate simultaneously.

Avant la mise en fonctionnement du dispositif, les quatre caissons (1) sont situés sous la cloche de mise sous vide (7). Les caissons ont les portes latérales (2) ouvertes, les compacteurs conformateurs (3) sont immobiles et le joint télescopique (22) est en position haut. Le système de pesée (23) a reçu une dose pré-déterminée de substance à ensacher .Before the device is put into operation, the four boxes (1) are located under the vacuum bell (7). The boxes have the side doors (2) open, the shaping compactors (3) are stationary and the telescopic seal (22) is in the high position. The weighing system (23) received a predetermined dose of substance to be bagged.

Au poste Pl du niveau A, on place le sac de conditionnement (21) dont la partie haute est maintenue ouverte automatiquement ou manuellement au-dessus de la goulotte (4) . En agissant sur la pédale (28) on provoque l'émergence de crochets ou de pinces (5) sur lesquels on accroche le sac (21) . En actionnant par l'air comprimé, ou manuellement (27) les vérins (non représentés) qui commandent les barrettes d'étanchéité (6), on provoque le plaquage du sac sur la goulotte sur toute sa périphérie. Les barrettes épousent parfaitement la forme extérieure de la goulotte rigide (4) avec, comme joint, le haut du sac (21).At position Pl of level A, the conditioning bag (21) is placed, the upper part of which is kept open automatically or manually above the chute (4). By acting on the pedal (28) it causes the emergence of hooks or clamps (5) on which the bag (21) is hung. By actuating the compressed air (or manually (27) the jacks (not shown) which control the sealing bars (6), the bag is pressed against the chute over its entire periphery. The bars perfectly match the external shape of the rigid chute (4) with, as a seal, the top of the bag (21).

Ces opérations terminées, le plateau (16) tourne, entrainant l'ensemble au poste P2 A ce poste de travail, la cloche sous vide (7) est maintenue en position haute, le caisson (1) a ses portes latérales qui se referment, enfermant ainsi le sac (21) dans le caisson conformateur (3).These operations completed, the plate (16) rotates, driving the assembly to station P2. At this work station, the vacuum chamber (7) is held in the high position, the box (1) has its side doors which close, thus enclosing the bag (21) in the shaping box (3).

Au poste de travail P3 le sac reçoit les matériaux à ensacher par l'intermédiaire de la goulotte (4) reliée au dispositif de pesage par le joint télescopique (22) qui s'abaisse et se plaque sur la partie de la goulotte (4) . Cette opération déclenche l'écoulement d'un volume prépesé de matériau dans le sac (21). Le remplissage terminé, le joint télescopique (22) se relève, et le sac (21) placé dans le conformateur compacteur situé sur le plateau tournant (16) subit une rotation vers le dernier poste P4 au niveau D .At workstation P3 the bag receives the materials to be bagged via the chute (4) connected to the weighing device by the telescopic seal (22) which lowers and is pressed onto the part of the chute (4) . This operation triggers the flow of a pre-weighed volume of material into the bag (21). When the filling is complete, the telescopic seal (22) is raised, and the bag (21) placed in the compacting shaper located on the turntable (16) is rotated towards the last station P4 at level D.

Au poste P4 le vibreur du compacteur conformateur s'arrête, la barrette d'étanchéité (6) s'ouvre, libérant ainsi le haut du sac de la goulotte (4). L'ensemble caisson (1) , compacteur conformateur (3) fermé par ses portes d'étanchéité, et le sac, sont placés sous la cloche de mise sous vide (7). Celle-ci, mobile verticalement, s'abaisse et vient se coller sur le haut du caisson (1) constituant ainsi un ensemble étanche grâce au joint (14).At station P4, the vibrator of the conforming compactor stops, the sealing strip (6) opens, thus freeing the top of the bag from the chute (4). The box assembly (1), conforming compactor (3) closed by its sealing doors, and the bag, are placed under the vacuum bell (7). The latter, movable vertically, lowers and sticks to the top of the box (1) thus constituting a sealed assembly thanks to the seal (14).

Dès que la cloche de mise sous vide a touché le caisson compacteur conformateur (3) le pompage commence jusqu'à l'obtention d'un vide satisfaisant du sac . A ce moment de l'opération, à partir de commandes électriques ou manuelles, les tendeurs nettoyeurs (8) sortent et dépoussièrent le haut du sac tandis qu'un jeu de barres de serrage forte pression (9) commandé par des vérins, obture le sac et provoque une soudure par thermo-compression ; la soudure terminée, les barres de serrage s'ouvrent, la hotte de mise sous vide se relève (7) , et le caisson compacteur conformateur (3) libère le sac (21) .As soon as the vacuum bell has touched the shaping compactor box (3), pumping begins until a satisfactory vacuum is obtained from the bag. At this time of the operation, using electrical or manual controls, the cleaning tensioners (8) come out and dust the top of the bag while a set of high pressure clamping bars (9) controlled by jacks, blocks the bag and causes thermo-compression welding; when the welding is finished, the clamping bars open, the vacuum hood is raised (7), and the shaping compactor box (3) releases the bag (21).

Les opérations de mise en place du sac, d'ensachage, de compacification, de mise sous vide et de soudage , étant simultannées dès que le poste Pl est libéré, un nouveau sac est immédiatement accroché, pour subir les mêmes opérations. L'ensemble constituant un système continu d'ensachage où les postes de travail sont continuellement alimentés.The operations of placing the bag, bagging, compacification, evacuating and welding, being simultaneous as soon as the station Pl is released, a new bag is immediately hooked, to undergo the same operations. The whole constituting a continuous bagging system where the workstations are continuously supplied.

La simultannéité des postes de travail.est obtenue au moyen de commandes électriques qui gèrent la continuité des opérations et assurent le fonctionnement automatique de l'ensemble .The simultaneity of the workstations is obtained by means of electric controls which manage the continuity of operations and ensure the automatic operation of the assembly.

Suivant une caractéristique importante de l'invention, on a représenté sur la figure 3 de la planche III/11, le caisson compacteur conformateur utilisé pour la conduite et la mise en forme du sac .According to an important characteristic of the invention, there is shown in Figure 3 of plate III / 11, the shaping compactor box used for driving and shaping the bag.

Ce caisson compacteur conformateur se décompose en un caisson rigide (1) extérieur, équipé de deux portes latérales (2) qui se referment sur un joint d'étanchéité (13).This conforming compactor box is broken down into an external rigid box (1), equipped with two side doors (2) which close on a seal (13).

A l'intérieur de ce caisson on trouve le compacteur conformateur (3) formé par un parallèlèpipède dépourvu de parois latérales et de couvercle et qui repose sur des vibreurs mécaniques (30) et des blocs de caoutchouc (29) . Ce caisson compacteur conformateur qui reçoit le sac de conditionnement (21) se déplace horizontalement sur des glissières (18) et (19) pendant les opérations d'ensachage.Inside this box there is the shaping compactor (3) formed by a parallelepiped devoid of side walls and cover and which rests on mechanical vibrators (30) and rubber blocks (29). This conforming compactor box which receives the conditioning bag (21) moves horizontally on slides (18) and (19) during the bagging operations.

Suivant une autre caractéristique de l'invention on a rprésenté sur les figures 4 et 5 de la planche IV/11 suivant une coupe transversale et une section , les différents éléments qui accompagnent la goulotteAccording to another characteristic of the invention, the various elements which accompany the chute are shown in FIGS. 4 and 5 of the board IV / 11 in a cross section and a section.

La goulotte (4) a la forme d'un tronc de cône de section ovale, dont les extrémités latérales (32) constituent des cheminées indépenantes permettant l'évacuation de l'air lors du remplissage du sac. A la partie inférieure de cette goulotte se situent des bras articulés qui s'écartent à la commande et constituent les accroche-sacs (5).The chute (4) has the shape of a truncated cone of oval section, the lateral ends (32) of which constitute independent chimneys allowing the evacuation of air during filling of the bag. At the lower part of this chute are articulated arms which move away from the control and constitute the bag hangers (5).

En-dessous de ces accroche-sacs, les barres de serrage (6) épousent exactement la forme ovale de la goulotte afin d'obtenir une bonne étanchéité à la poussière . Ces barres de serrage (6) forment avec la goulotte, sur les extrémités droites des pinces 31 permettant d'assurer une parfaite étanchéité .Below these bag hangers, the clamping bars (6) follow exactly the oval shape of the chute in order to obtain a good dust-tightness. These clamping bars (6) form with the chute, on the straight ends of the clamps 31 to ensure a perfect seal.

Les figures 6a, 6b, 6c, 6d, be, 6f, 6g de la planche V/11 permettent de décrire le fonctionnement de l'ensemble des éléments constitutifs de la goulotte et du caisson compacteur conformateur .Figures 6a, 6b, 6c, 6d, be, 6f, 6g of the board V / 11 describe the operation of all the constituent elements of the chute and the shaping compactor box.

Les figures 6a, 6b, 6c, 6d, 6e, 6f, 6g , 7, 8 , 9 et 10 constituent un ensemble de schémas représentant le fonctionnement de l'ensemble du dispositif.Figures 6a, 6b, 6c, 6d, 6e, 6f, 6g, 7, 8, 9 and 10 constitute a set of diagrams representing the operation of the entire device.

En se reportant à la figure 6a, on découvre le sac (21) enfilé sur la goulotte (4), et en actionnant la pédale (28), les accroche-sacs (5) se tendent, maintenant le sac sous la goulotte.Referring to Figure 6a, we discover the bag (21) threaded on the chute (4), and by actuating the pedal (28), the bag hooks (5) tighten, keeping the bag under the chute.

A la figure,6b, la commande manuelle symbolisée par la pédale (27) permet d'actionner les barres d'étanchéité (b) qui provoquent le plaquage du haut du sac (21) sur le bas de la goulotte (4), entrainant automatiquement l'extension des bras accroche-sacs (5).In FIG. 6b, the manual control symbolized by the pedal (27) makes it possible to actuate the sealing bars (b) which cause the top of the bag (21) to be pressed against the bottom of the chute (4), causing automatically extending the bag hooks (5).

L'arrimage du sac (21) à la goulotte (4) et le positionnement du sac (21) dans le caisson (1) à l'intérieur du compacteur conformateur (3) sont représentés sur la figure 6c.The securing of the bag (21) to the chute (4) and the positioning of the bag (21) in the box (1) inside the shaping compactor (3) are shown in Figure 6c.

Les schémas 6d et 6e figurent le positionnement du sac (21) dans le compacteur conformateur (3) qui repose sur les vibreurs (30) .Diagrams 6d and 6e show the positioning of the bag (21) in the shaping compactor (3) which rests on the vibrators (30).

Dès que le remplissage du sac commence, les vibreurs commencent à fonctionner. Pendant toutes ces opérations, les portes (2) du caisson rigide (1), non représentées sur ces dessins, ont été fermées, afin d'assurer une bonne conformité du sac.As soon as the filling of the bag begins, the vibrators start to work. During all these operations, the doors (2) of the rigid box (1), not shown in these drawings, were closed, in order to ensure good compliance of the bag.

Les figures 6f et 6g schématisent l'opération de fin de remplissage du sac qui, dès qu'elle est terminée, stoppe les vibreurs (30) du compacteur; dès ce moment les barrettes d'étanchéité (6) s'ouvrent, libérant le sac de la goulotte (4), qui remonte. L'ensemble sac (21) enfermé dans le caisson compacteur, glisse à ce moment vers la cloche de mise sous vide.Figures 6f and 6g show diagrammatically the end of filling of the bag operation, which, as soon as it is finished, stops the vibrators (30) of the compactor; from this moment the sealing bars (6) open, releasing the bag from the chute (4), which rises. The bag assembly (21) enclosed in the compactor box, slides at this time towards the vacuum bell.

En se reportant à la figure 7 de la planche V1/11 le sac (21) empli de matériau compacifié est placé dans le caisson compacteur (3), les portes (2) plaquées sur les joints d'étanchéité (13). Les tendeurs nettoyeurs (8) constitués de raclettes métalliques sont rentrés . Le dispositif de mise sous vide (7) est en position haute, raccordé au dispositif de pompage par la tubulure (11). Les barres de serrage (9) et (10) montées sur glissières sont en position écartées. Le joint d'étanchéité (14) , collé sur le bas de la hotte (7) est face à face avec le haut du caisson compacteur conformateur ouvert.Referring to FIG. 7 of the board V1 / 11, the bag (21) filled with compacted material is placed in the compactor box (3), the doors (2) pressed against the seals (13). The cleaning tensioners (8) consisting of metal scrapers are retracted. The vacuum device (7) is in the high position, connected to the pumping device by the tube (11). The clamping bars (9) and (10) mounted on slides are in the separated position. The seal (14), glued to the bottom of the hood (7) is face to face with the top of the conforming compactor box open.

Sur la figure 8 de 1a planche VII/11, la cloche (7) s'est déplacée verticalement pour se placer sur le haut du caisson compacteur conformateur (3), assurant, grâce au joint d'étanchéité (14), une enceinte étanche . La mise sous vide de l'ensemble est obtenue au moyen d'un système de pompage raccordé à la canalisation 11. Le haut du sac (21) est complètement ouvert tandis que les barres de serrage (9) et (10) sont encore écartées.In FIG. 8 of plate VII / 11, the bell ( 7 ) has moved vertically to be placed on the top of the shaping compactor box (3), ensuring, thanks to the seal (14), a sealed enclosure . The assembly is evacuated by means of a pumping system connected to the pipe 11. The top of the bag (21) is completely open while the clamping bars (9) and (10) are further apart .

La figure 9 de la planche VIII/11 représente l'ensemble du dispositif placé sous vide . On commande alors le mouvement des bras nettoyeurs (8) qui nettoient et tendent le haut du sac. Cette dernière opération terminée, les barres de serrage forte pression (9) commencent à pincer le haut du sac, les bras des tendeurs nettoyeurs (8) s'effacent , tandis que simultanément les barres de soudure se referment sur le haut du sac pour réaliser l'obturation définitive du sac.Figure 9 of plate VIII / 11 shows the entire device placed under vacuum. We then control the movement of the cleaning arms (8) which clean and stretch the top of the bag. This last operation finished, the high pressure clamping bars (9) begin to pinch the top of the bag, the arms of the cleaning tensioners (8) disappear, while simultaneously the bars of solder closes on the top of the bag to achieve the final sealing of the bag.

On a représenté sur les figures 10a, 10b, 10c de la planche IX/11, les opérations de dégagement du sac .There is shown in Figures 10a, 10b, 10c of the board IX / 11, the bag release operations.

Aux figures 10a et 10b, le sac sous vide (21) complètement obturé par une soudure, les barres (10) s'écartent La remise à pression atmosphèrique de l'enceinte est obtenue par l'ouverture d'une électrovanne permettant ainsi à la hotte (7) de s'élever du caisson compacteur conformateur (3). Les portes latérales (2) du caisson rigide s'ouvrent et le sac (21) complètement conditionné peut être récupéré manuellement maintenu par les barres de serrage (9), suivant le schéma figuré en 10cIn FIGS. 10a and 10b, the vacuum bag (21) completely closed by a weld, the bars (10) move apart. The atmospheric pressure return of the enclosure is obtained by the opening of a solenoid valve thus allowing the hood (7) to rise from the shaping compactor box (3). The side doors (2) of the rigid box open and the completely conditioned bag (21) can be recovered manually maintained by the clamping bars (9), according to the diagram shown in 10c

On a représenté sur les figures 11a et 11b de la planche X/11 l'opération de récupération du sac (21). Ce dernier maintenu par les barres de serrage (9) a coulissé sur un tapis roulant (34), tandis que des flasques latérales, dans un mouvement horizontal, au moyen d'un système télescopique, maintenant le sac en position verticale. A ce moment, les barres de serrage (9) s'écartent et libérent complètement le sac de l'ensemble du dispositif.There is shown in Figures 11a and 11b of the board X / 11 the recovery operation of the bag (21). The latter held by the clamping bars (9) has slid on a conveyor belt (34), while lateral flanges, in a horizontal movement, by means of a telescopic system, maintaining the bag in vertical position. At this time, the clamping bars (9) move apart and completely release the bag from the entire device.

. En se reportant à la figure 12a et à la figure 12b représentées sur la planche XI/11, on trouvé le joint tëlescopique (22) qui. relie la goulotte (4) à l'organe de dosage (23). Sur la figure 12a le joint télescopique (22) est en position haute, garni à sa base, d'une rondelle d'étanchéité (15),. Referring to Figure 12a and Figure 12b shown on the board XI / 11, we find the telescopic seal (22) which. connects the chute (4) to the metering member (23). In FIG. 12a, the telescopic seal (22) is in the high position, fitted at its base, with a sealing washer (15),

Lorsque le sac (21) se présente sous la goulotte (4), le joint télescopique (22) descend et se plaque sur le haut de la goulotte rigide (4) assurant l'étanchéité. Les matériaux s'écoulent depuis le dispositif de pesée (23) jusque dans le sac, tandis que l'air contenu dans ce dernier s'échappe par les cheminées (32) comme il est représenté à la figure 12b.When the bag (21) is under the chute (4), the telescopic seal (22) descends and is pressed onto the top of the rigid chute (4) ensuring the seal. The materials flow from the weighing device (23) into the bag, while the air contained in the latter escapes through the chimneys (32) as shown in Figure 12b.
