L'invention sera plus particulièrement utilisée pour l'équipement d'installations mises en place dans des lieux aptes à dispenser des repas collectifs tels que restaurants traditionnels, restaurants en libre-service, cantines, réfectoires de collectivité, lieux de restauration rapide etc...The invention will be more particularly used for the equipment of installations set up in places suitable for providing collective meals such as traditional restaurants, self-service restaurants, canteens, community dining halls, fast food places, etc. .

Les machines qui ont été réalisées jusqu'à présent en vue d'automatiser le travail de lavage de vaisselle dans les installations collectives présentent toutes un certain nombre d'inconvénients, notamment l'encombrement, les manipulations à l'entrée et à la sortie, une consommation excessive en eau et en énergie thermique et enfin un état final de la vaisselle peu satisfaisant par suite de dépôt de produits actifs concentrés à la surface après séchage.The machines which have been produced up to now with a view to automating the work of washing dishes in collective installations all have a certain number of drawbacks, in particular the bulk, the handling at the entry and at the exit, excessive consumption of water and thermal energy and finally an unsatisfactory final state of the dishes as a result of deposition of concentrated active products on the surface after drying.

L'invention vise à remédier à ces divers inconvénients et propose à cet effet un procédé et un dispositif appliquant une méthodologie nouvelle et un appareillage plus efficace, plus compacté et totalement automatique.The invention aims to remedy these various drawbacks and proposes for this purpose a method and a device applying a new methodology and a more efficient, more compact and fully automatic apparatus.

Ainsi qu'on le verra tout au long du présent mémoire descriptif, le procédé de lavage collectif d'articles de vaissellerie utilise une seule opération humide de lavage en eau détergente, qui est recyclée après filtration et maintenue à une température modérée de l'ordre de 60°, tandis ' que l'eau de lavage unique et les produits actifs qu'elle contient, est éliminée de la surface des articles non pas par rinçage humide mais par raclage physique, de préférence sous forme d'une rampe éjectant une lame d'air chassant le film humide dans le sens de la gravité.As will be seen throughout this specification, the collective washing process for tableware uses a single wet washing operation in detergent water, which is recycled after filtration and maintained at a moderate temperature of the order 60 °, while the single wash water and the active products it contains is removed from the surface of the articles not by wet rinsing but by physical scraping, preferably in the form of a ramp ejecting an air knife chasing the wet film in the direction of gravity.

La machine selon l'invention peut être alimentée par un empilement d'articles sales correspondant à une certaine quantité, positionnés dans un conteneur standard, le personnel étant libérés des tâches de mise en place des plateaux dans la machine, mise en place qui est effectuée automatiquement à un poste d'alimentation, tandis que la machine restitue de façon continue à un poste de sortie une quantité ou empilement d'articles propres, disponibles pour un nouvel emploi immédiat.The machine according to the invention can be fed by a stack of dirty articles corresponding to a certain quantity, positioned in a standard container, the staff being freed from the tasks of placing the trays in the machine, which is carried out. automatically at a feeding station, while the machine continuously returns to an output station a quantity or stack of clean articles available for immediate re-use.

Plus particulièrement, l'invention concerne un procédé de lavage mécanique d'articles de platrerie ou vaissellerie plate telles que assiettes, soucoupes ou analogues, acheminés en continu, le procédé étant caractérisé en ce que les articles soumis à une phase humide par brossage rotatif sous projection d'eau détergente, sont ensuite soumis à une phase d'élimination physique du reliquat humide par projection d'une lame d'air suivant toute la surface des articles, maintenus en position inclinée, la lame d'air chassant le film liquide rémanent dans la direction de la pesanteur.More particularly, the invention relates to a mechanical washing process for articles of flatware or flat tableware such as plates, saucers or the like, conveyed continuously, the process being characterized in that the articles subjected to a wet phase by rotary brushing under projection of detergent water, are then subjected to a phase of physical elimination of the wet residue by projection of an air space along the entire surface of the articles, maintained in an inclined position, the air space chasing the residual liquid film in the direction of gravity.

Selon ce procédé, les articles sont acheminés tout au long du parcours à plat et selon un plan incliné ascendant tant au cours de la phase de brossage sous projection d'eau détergente qu'au cours de la phase d'élimination du film humide rémanent, et l'angle de cheminement ascendant des articles est compris entre 10 et 30°.According to this process, the articles are conveyed all along the flat course and in an ascending inclined plane both during the brushing phase under spraying with detergent water and during the phase of elimination of the residual wet film, and the upward tracking angle of the articles is between 10 and 30 °.

L'invention concerne encore un dispositif pour la mise en oeuvre du procédé ci-dessus, du type comportant un poste de brossage sous projection liquide d'eau détergente, une réserve d'eau détergente alimentée par le retour par gravité de l'eau provenant dudit poste de brossage humide, des moyens de recyclage de l'eau depuis cette réserve vers les moyens de projection d'eau détergente, et le dispositif est caractérisé en ce qu'il comporte en aval immédiat dudit poste de brossage humide des moyens de projection d'une lame d'air apte à racler et éliminer physiquement le film d'humidité rémanent à la surface des articles.The invention also relates to a device for setting using the above method, of the type comprising a brushing station under liquid spray of detergent water, a supply of detergent water supplied by the gravity return of the water coming from said wet brushing station, recycling means water from this reserve to the means for spraying detergent water, and the device is characterized in that it comprises immediately downstream of said wet brushing station means for projecting an air knife capable of scraping and physically removing the residual moisture film from the surface of the articles.

Other characteristics and advantages of the invention will emerge from the description which follows and which is given in relation to two particular embodiments presented by way of example without limitation.
  • Figure 1 shows a schematic longitudinal sectional view of the entire installation according to the invention.

En considérant l'ensemble des figures, on voit que le dispositif selon l'invention est constitué essentiellement d'un poste de lavage 2 suivi d'un poste 3 d'élimination physique du film humide qui constituent, accolés l'un à l'autre, le coeur de la machine ou du dispositif.Considering all of the figures, it can be seen that the device according to the invention essentially consists of a washing station 2 followed by a station 3 for the physical elimination of the wet film which constitute, attached to one other, the heart of the machine or device.

En amont, se trouve le poste d'alimentation 1 à partir de l'empilement amont 5 de produits sales, tandis que en aval se trouve le poste 4 de remise en piles 41 des produits propres.Upstream, there is the supply station 1 from the upstream stack 5 of dirty products, while downstream is the station 4 for re-storing 41 clean products.

Selon l'invention, la machine est alimentée à partir de conteneurs 54 constituant des cassettes interchangeables et qui seront utilisées pour le stockage, le transport, la réception des produits propres au poste aval 4, tout comme pour la mise en place de l'empilement des produits sales pour constituer la pile 5 des articles de vaissellerie plate destinés à être soumis au lavage continu dans la machine. Ces conteneurs peuvent être montés sur roulement pour constituer des chariots, (V. Fig 6, 7 et 8)According to the invention, the machine is supplied from containers 54 constituting interchangeable cassettes and which will be used for storage, transport, reception of the products specific to the downstream station 4, as well as for the establishment of the stack. dirty products to constitute the stack 5 of flat tableware intended to be subjected to continuous washing in the machine. These containers can be mounted on bearings to form trolleys, ( V. F ig 6, 7 and 8)

L'empilement de vaisselle 5 est mis en place au poste aval 1 à l'intérieur d'une cassette standard et le poste comporte à cet effet des moyens de repérage tels que la cassette soit mise en place automatiquement au bon emplacement pour permettre le travail et la préhension des organes de reprise schématisés en 6 (figure 1) et qui sont représentés en position de départ (en trait plein) et en position 6' d'arrivée pour alimenter la machine (en traits pointillés).The stack of dishes 5 is put in place at the downstream station 1 inside a standard cassette and the station includes for this purpose locating means such that the cassette is automatically placed in the right location to allow the work and gripping of the recovery members shown schematically in 6 (Figure 1) and which are shown in the starting position (in line full) and in position 6 'of arrival to supply the machine (in dotted lines).

Ce dispositif est formé d'un attelage 7 manoeuvré par le vérin 59 (voir figure 7 et 8) coulissant sur un ensemble de rails 8 et porteur d'un vérin 9 à la base duquel un système de préhension à ventouses 10 permet d'appréhender individuellement les assiettes, plats, plateaux etc... pour les amener à leur position de départ dans l'alimentation de-la machine.This device is formed by a coupling 7 operated by the jack 59 (see FIGS. 7 and 8) sliding on a set of rails 8 and carrying a jack 9 at the base of which a gripping system with suction cups 10 makes it possible to grasp the plates, dishes, trays etc ... to bring them to their starting position in the feeding of the machine.

Au poste de départ amont 1, on peut prévoir un système visant à éliminer physiquement les déchets solides ou pâteux qui peuvent subsister sur l'assiette, par exemple sous forme d'une projection d'un fluide destiné à chasser ces débris qui tombent dans le bac 11. Le fluide peut être liquide ou éventuellement de l'air et cette phase vise essentiellement à retirer physiquement de l'assiette les éléments solides de façon à livrer à la machine une assiette sale mais sans dépôts importants de matières solides.At the upstream departure station 1, a system can be provided for physically eliminating solid or pasty waste which may remain on the plate, for example in the form of a projection of a fluid intended to expel these debris which fall into the tank 11. The fluid may be liquid or possibly air and this phase essentially aims to physically remove the solid elements from the plate so as to deliver a dirty plate to the machine but without significant deposits of solid matter.

L'ensemble de la machine fonctionne en continu et à cet effet, les assiettes, plats, plateaux sont véhiculés par un moyen d'entrainement constitué de courroies crantés 12,12' coopérant avec des rails de guidage 13,13',14,14'. Les articles sont ainsi positionnés à plat et maintenus dans cette position selon un plan incliné ascendant. Les rails 13,13',14,14' sont de simples supports fixes et passifs permettant le glissement ascendant des articles de vaissellerie tels que les assiettes 15,15', 16,16'.The whole machine operates continuously and for this purpose, the plates, dishes, trays are conveyed by a drive means consisting of toothed belts 12,12 'cooperating with guide rails 13,13', 14,14 '. The articles are thus positioned flat and maintained in this position along an ascending inclined plane. The rails 13,13 ', 14,14' are simple fixed and passive supports allowing the upward sliding of the tableware such as 15.15 ', 16.16' plates.

Les rails sont par exemple constitués de supports linéaires fixes formés plus particulièrement de cordons en matière synthétique semi-rigides extrudés et offrant une paroi extérieure lisse et à faible coefficient de frottement, éventuellement supportée en position inférieure par une tige rigide telle qu'une tige plate en acier inoxydable 17,17'(figure 2).The rails for example consist of fixed linear supports formed more particularly of semi-rigid extruded synthetic cords and offering a smooth outer wall with low friction coefficient, possibly supported in the lower position by a rigid rod such as a flat rod 17.17 'stainless steel (Figure 2).

Les rails constituent de simples moyens de glissement permettant d'assurer le positionnement constant des assiettes le long de leur parcours ascensionnel et à cet effet, les rails sont disposés selon un parcours en plan incliné formant un angle de l'ordre de 15 à 20° avec l'horizontale.The rails constitute simple sliding means making it possible to ensure the constant positioning of the plates along their upward course and for this purpose, the rails are arranged along a course in inclined plane forming an angle of the order of 15 to 20 °. with the horizontal.

Entre deux rails voisins et récepteurs d'un train d'assiettes successives est disposée une courroie d'entrainement crantée 12 et 12' qui repose elle-même sur un support inférieur 18 formé par exemple d'une tige rigide à section carrée par exemple en acier inoxydable (figures 2 et 3).Between two adjacent and receiving rails of a train of successive plates is arranged a notched drive belt 12 and 12 'which itself rests on a lower support 18 formed for example of a rigid rod with square section for example in stainless steel (Figures 2 and 3).

On voit que les assiettes sont ainsi acheminées depuis leur arrivée au poste aval 1 à travers la machine et elles traversent le poste de lavage 2 et le poste d'élimination du film humide 3.It can be seen that the plates are thus routed from their arrival at the downstream station 1 through the machine and they pass through the washing station 2 and the wet film elimination station 3.

Selon l'invention, le procédé et la machine qui met en oeuvre ce procédé comportent une seule phase humide réalisée au poste 2; à ce poste sont projetés depuis les buses supérieures 19 et inférieures 20, des jets d'eau détergente à température de l'ordre de 60° C qui atteignent la surface supérieure et la surface inférieure de l'assiette 15; cette opération est couplée à un brossage depuis la brosse rotative 21 et permet d'éliminer tout dépôt sur les parois de l'assiette.According to the invention, the method and the machine which implements this method comprise a single wet phase carried out at station 2; at this station, water jets are sprayed from the upper nozzles 19 and lower 20 detergent at a temperature of the order of 60 ° C which reaches the upper surface and the lower surface of the plate 15; this operation is coupled to brushing from the rotary brush 21 and makes it possible to eliminate any deposit on the walls of the plate.

Une paroi 60(figure 6) sépare le poste de lavage de l'amont et elle comporte deux lèvres 61,62 en matériau élastiquement déformable apte à se prêter au passage des articles en épousant et en raclant leurs faces supérieure et inférieure. Cette paroi 60 maintient l'eau au poste de lavage.A wall 60 (Figure 6) separates the washing station from upstream and it has two lips 61,62 of elastically deformable material capable of lending itself to the passage of articles by marrying and scraping their upper and lower faces. This wall 60 keeps the water at the washing station.

L'eau s'écoulant de ce poste de lavage rejoint par les plans inclinés 22,23 le bac récepteur 24 en traversant un dégrilleur 25, de sorte que l'eau dans le bac ne comporte pas de résidus solides qui ont été retenus par le dégrilleur 25; cette eau peut être recyclée par la pompe 26 vers les buses de projection 19 et 20. L'eau de lavage est reguliérement renouvelée. L'article qui sort du poste de lavage est donc propre mais comporte à sa surface un film humide d'eau de lavage. Cette eau contient les produits actifs (détergents et bactéricides) selon un dosage approprié et évitant tout excès mais il est clair que ce résidu ou ce film humide doit être éliminé.The water flowing from this washing station joins the receiving tank 24 through the inclined planes 22, 23 through a screen 25, so that the water in the tank does not contain solid residues which have been retained by the screen 25; this water can be recycled by the pump 26 to the spray nozzles 19 and 20. The washing water is regularly renewed. The article which leaves the washing station is therefore clean but has on its surface a wet film of washing water. This water contains the active products (detergents and bactericides) according to an appropriate dosage and avoiding any excess, but it is clear that this residue or this wet film must be eliminated.

Contrairement aux dispositifs antérieurs dans lesquels l'élimination se faisait à grand renfort d'énergie par un rinçage constituant en réalité une dilution des produits actifs, suivis d'un séchage aboutissant à concentrer les résidus à la surface de l'assiette, l'invention procède par une élimination physique en rejetant par raclage le film humide dans le sens de la pesanteur, le film étant chassé sous forme de goutelettes qui rejoignent le bac de lavage 24.Unlike the previous devices in which the elimination was done with great energy reinforcement by a rinsing constituting in reality a dilution of the active products, followed by a drying resulting in concentrating the residues on the surface of the plate, the invention proceed by a physical elimination by rejecting by scraping the wet film in the direction of the gravity, the film being expelled in the form of droplets which join the washing tub 24.

Dans le cadre de l'exemple réalisé, on a mis en oeuvre une lame d'air projeté à partir de la buse supérieure 27.In the context of the example carried out, an air knife projected from the upper nozzle 27 was used.

Symétriquement une buse inférieure 28 projette à la base de l'assiette un flux d'air sous forme de lame qui racle et repousse vers l'extrémité arrière, sous forme de gouttelettes qui retombent ensuite dans le bac, le film ou pellicule humide qui subsistent sur l'embase de l'assiette.Symmetrically a lower nozzle 28 projects at the base of the plate an air flow in the form of a blade which scrapes and pushes towards the rear end, in the form of droplets which then fall back into the tank, the remaining film or wet film on the base of the plate.

Les buses 27,28 forment des rampes projetant un flux d'air formant une lame disposée selon un plan incliné par rapport au plan général de l'assiette selon un angle légèrement inférieur à la perpendiculaire et de l'ordre de 75°.The nozzles 27, 28 form ramps projecting an air flow forming a blade arranged in an inclined plane relative to the general plane of the plate at an angle slightly less than the perpendicular and of the order of 75 °.

Les assiettes sont alors acheminées au poste de desserte où elles sont délivrées par la courroie crantée 12; ce poste de desserte peut être un poste d'attente intermédiaire 29 où les assiettes individuelles entrent en repoussant le cliquet 30 qui vient se repositionner à l'arrière de l'assiette, ce cliquet étant situé à l'extrémité du piston 31 manoeuvre par le vérin 32. Le piston représenté en traits pointillés en position d'extension et en traits pleins en position de rétraction est apte à ramener l'assiette vers l'extérieur, c'est-à-dire vers le poste de remise en piles.The plates are then sent to the serving station where they are delivered by the toothed belt 12; this serving station can be an intermediate waiting station 29 where the individual plates enter by pushing the pawl 30 which is repositioned at the rear of the plate, this pawl being located at the end of the piston 31 maneuvered by the cylinder 32. The piston shown in dotted lines in the extended position and in solid lines in the retracted position is capable of bringing the plate outward, that is to say towards the re-stacking station.

A ce poste de remise en piles est manoeuvré un descenseur constitué d'un train ou attelage support 33 monté sur une ou deux colonnes de guidage et manoeuvré par la tige du piston 34 provenant du vérin de manoeuvre verticale 35. L'attelage 33 comporte un dispositif support et de dépose des assiettes représentées à la figure 5 et constitués des deux bras 36,37 de supportage de l'assiette 38 figurés en position haute, en traits pleins (et en position inférieure et de dépose en traits pointillés).At this re-stacking station is operated a descender consisting of a support train or hitch 33 mounted on one or two guide columns and operated by the piston rod 34 coming from the actuating cylinder vertical 35. The coupling 33 comprises a device for supporting and removing the plates shown in FIG. 5 and consisting of the two arms 36, 37 for supporting the plate 38 shown in the high position, in solid lines (and in the lower position and dotted lines).

Les deux bras sont associés chacun à un vérin de manoeuvre 39,40, de sorte que les bras peuvent être amenés en position rapprochée pour supporter l'assiette puis écartée pour permettre la dépose de l'assiette au sommet de la pile.The two arms are each associated with an actuating cylinder 39.40, so that the arms can be brought into the close position to support the plate and then moved apart to allow the plate to be deposited at the top of the stack.

L'ensemble des vérins 35,39 et 40 est associé à un dispositif de commande et d'asservissement (non représenté) comportant lui-même des contacteurs aptes à déceler la présence de l'assiette 38 en position d'arrivée sur les bras rapprochés 36,37, ce qui commande le départ du cycle avec abaissement de l'attelage 33 jusqu'au sommet de la pile 41; l'arrêt est commandé par un contacteur associé au train 33 et venant par exemple en butée sur l'assiette supérieure 42, ce qui provoque l'arrêt du vérin et le positionnement à hauteur convenable de l'attelage 33; par la suite les deux vérins 39 et 40 sont amenés en position d'écartement de sorte que l'assiette 38 soit déposée sur l'assiette supérieure 42; après quoi le train 33 peut être remonté avec rapprochement des bras 36 et 37 pour revenir à la position haute ou de départ du cycle.All of the jacks 35, 39 and 40 are associated with a control and servo-control device (not shown) itself comprising contactors capable of detecting the presence of the plate 38 in the arrival position on the close arms 36.37, which controls the start of the cycle with lowering of the coupling 33 to the top of the stack 41; the stop is controlled by a contactor associated with the train 33 and coming for example in abutment on the upper plate 42, which causes the stop of the jack and the positioning at suitable height of the coupling 33; subsequently the two jacks 39 and 40 are brought into the spacing position so that the plate 38 is deposited on the upper plate 42; after which the train 33 can be raised with approximation of the arms 36 and 37 to return to the high position or start of the cycle.

L'invention permet de réaliser un appareillage compacté et à fonctionnement entièrement automatique.The invention makes it possible to produce compact, fully automatic apparatus.

L'écartement entre les rails 13,13',14,14' correspond à un intervalle inférieur à la moitié de la plus petite dimension en largeur des articles de vaissellerie en s'opposant ainsi à la chute d'un article entre deux rails.The spacing between the rails 13,13 ', 14,14' corresponds to an interval of less than half the smallest width dimension of the items of tableware, thus opposing the fall of an article between two rails.

Les courroies crantées 12,12', sont montées sur deux poulies d'extrémité dont une poulie motrice 47, la courroie étant ainsi apte à suivre un parcours aller ascendant, étant positionnée entre deux rails fixes formant chemin de guidage, et un parcours retour inverse inférieur, les crantages étant en position débordant vers l'extérieur pour faire prise sur les articles soumis au lavage.The toothed belts 12,12 ′ are mounted on two end pulleys, one of which is a drive pulley 47, the belt thus being able to follow an upward path, being positioned between two fixed rails forming a guide path, and a reverse return path. lower, the notches being in position projecting outward to grip on the articles subjected to washing.

Les figures 6,7,8 montrent une variante dans laquelle la machine assure le lavage de plateaux, qui sont acheminés selon un parcours ascendant, étant guidés et entraînés par un train de galets latéraux.Figures 6,7,8 show a variant in which the machine is washing trays, which are routed in an ascending path, being guided and driven by a train of side rollers.

Comme on le voit plus spécialement sur ces figures, la machine comporte en amont un poste de stockage des articles de vaissellerie à l'état sale et situés sous les moyens de reprise et de déplacement (6,10,8); en aval, la machine comporte un poste de stockage des articles de vaissellerie propres et chaque poste de stockage amont et aval est apte à recevoir un conteneur amovible 54 formant une cassette (par exemple montée sur moyens de roulement) et dans laquelle peut-être positionné un empilement d'articles de vaissellerie disposés horizontalement en reposant l'un sur l'autre; chaque conteneur est ainsi apte à être mis en place au poste de stockage amont pour délivrer les articles de vaissellerie sales repris par la machine et le même conteneur une fois vide peut être amené au poste de stockage aval pour recevoir les articles de vaissellerie propres délivrés par la machine, chaque conteneur se trouvant par ailleurs constituer une cassette de stockage des articles soit à l'état sale soit à l'état propre.As can be seen more particularly in these figures, the machine comprises upstream a storage station for tableware in the dirty state and located under the recovery and displacement means (6,10,8); downstream, the machine comprises a storage station for clean tableware and each upstream and downstream storage station is capable of receiving a removable container 54 forming a cassette (for example mounted on rolling means) and in which can be positioned a stack of tableware arranged horizontally resting on each other; each container is thus able to be put in place at the upstream storage station to deliver dirty cutlery items picked up by the machine and the same container, once empty, can be brought to the downstream storage station to receive the cutlery items clean delivered by the machine, each container also being a storage cassette for articles either in the dirty state or in the clean state.
