Description

On sait que pour des raisons évidentes d'hygiène, en fin de travail, tous les outils et équipements utilisés dans les abattoirs et autres laboratoires ou ateliers de l'industrie agro-alimentaire doivent faire l'objet d'un nettoyage complet effectué dans un milieu aseptisé. Un tel nettoyage pose un problème assez ardu lorsqu'il concerne un nombre important d'opérateurs au sein d'une même entreprise et les installations proposées jusqu'à ce jour ne se sont pas révélées entièrement satisfaisantes.We know that for obvious reasons of hygiene, at the end of work, all the tools and equipment used in slaughterhouses and other laboratories or workshops in the food industry must be thoroughly cleaned in a sanitized environment. Such cleaning poses a rather difficult problem when it concerns a large number of operators within the same company and the installations proposed to date have not proved entirely satisfactory.

La présente invention a pour objet une laveuse industrielle spécialement conçue pour assurer la manutention et le nettoyage automatiques des outils et équipements du genre susvisé, et ce sans aucune intervention manuelle et tout en permettant d'individualiser les outils et équipements de chaque opérateur.The present invention relates to an industrial washer specially designed to provide automatic handling and cleaning of the tools and equipment of the aforementioned kind, and this without any manual intervention and while making it possible to individualize the tools and equipment of each operator.

La laveuse suivant l'invention est définie à la revendication 1.The washer according to the invention is defined in claim 1.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 7 enfin est une coupe horizontale schématique illustrant l'agencement et le fonctionnement des rampes et buses d'aspersion.Fig. 7 finally is a schematic horizontal section illustrating the arrangement and operation of the spray nozzles and nozzles.

La laveuse représentée en fig. 1 comprend essentiellement un tunnel de stockage 1 pourvu à chacune de ses extrémités d'une tour verticale 2, respectivement 3.The washer shown in fig. 1 essentially comprises a storage tunnel 1 provided at each of its ends with a vertical tower 2, respectively 3.

Le tunnel 1 est constitué en assemblant bout-à-bout, par exemple par simple boulonnage, des caisssons élémentaires 4 dont le nombre varie en fonction de l'importance du laboratoire envisagé. Comme montré en fig. 2, chaque caisson 4 est ouvert à ses deux extrémités afin que son espace intérieur communique librement avec celui des deux caissons adjacents. Il est constitué par une paroi arrière verticale 5 solidaire d'un toit 6 et d'un fond inférieur 7, l'espace intérieur ainsi défini étant fermé par une porte d'accès latéral 8 articulée sur un pivot 6a de manière à pouvoir être relevée à la manière illustrée en 8' .The tunnel 1 is formed by assembling end-to-end, for example by simple bolting, elementary boxes 4, the number of which varies according to the size of the laboratory envisaged. As shown in fig. 2, each box 4 is open at its two ends so that its internal space communicates freely with that of the two adjacent boxes. It consists of a vertical rear wall 5 secured to a roof 6 and a bottom bottom 7, the interior space thus defined being closed by a lateral access door 8 hinged on a pivot 6 a so as to be able to be noted in the manner illustrated in 8 '.

On observera que le fond 7 présente en section transversale un profil en V de façon à recueillir les égouttements et à diriger ceux-ci vers une canalisation d'évacuation 9.It will be observed that the bottom 7 has a V-shaped profile in cross section so as to collect the drips and direct them towards an evacuation pipe 9.

A l'intérieur de chacun des caissons 4 qui forment le tunnel de stockage 1 sont prévues deux voies superposées de guidage qui s'étendent sur toute la longueur du caisson envisagé de manière à prolonger en quelque sorte les deux voies de chacun des deux caissons contigus. Chaque voie de guidage est constituée par deux fers horizontaux à profil en C qui s'ouvrent en vis-à-vis, ces fers ayant été référencés 10 pour la voie supérieure, 11 pour la voie inférieure.Inside each of the boxes 4 which form the storage tunnel 1 are provided two superimposed guide tracks which extend over the entire length of the box envisaged so as to extend in a way the two tracks of each of the two adjacent boxes . Each guide track is formed by two horizontal bars with a C profile which open opposite, these bars having been referenced 10 for the upper track, 11 for the lower track.

Chaque voie 10 ou 11 est destinée à assurer le guidage d'une série de chariots 12 dont l'agencement a été détaillé en fig. 3. Chacun de ces chariots 12 comprend deux barres parallèles 13 réunies par deux flasques latéraux 14, chaque flasque étant équipé de deux galets 15 qui sont disposés à l'extérieur pour être aptes à rouler à l'intérieur du profil en C des fers 10 ou 11. L'une des barres 13 est solidaire de deux tiges verticales 16 dont les extrémités inférieures coudées portent une rampe 17, tandis que vers le haut elles sont réunies par un guide 18 à section en forme de double équerre.Each track 10 or 11 is intended to guide a series of carriages 12, the arrangement of which has been detailed in FIG. 3. Each of these carriages 12 comprises two parallel bars 13 joined by two lateral flanges 14, each flange being equipped with two rollers 15 which are arranged outside to be able to roll inside the C profile of the irons 10 or 11. One of the bars 13 is integral with two vertical rods 16 whose bent lower ends carry a ramp 17, while upwards they are joined by a section guide 18 in the form of a double square.

Chaque chariot 12 est destiné à recevoir de manière amovible un cadre 19 qui est agencé pour loger l'ensemble des outils et équipements individuels d'un opérateur. Dans l'exemple considéré, le cadre 19 comporte deux plaquettes horizontales superposées 20 découpées de perforations aptes à former logements pour des couteaux de découpage et un fusil d'aiguisage, ces outils étant introduits verticalement par le haut ; aux deux plaquettes 10 est associé un support 21 en forme de main, profilé pour recevoir un gant de protection à mailles. Une fois les outils et équipements mis en place, l'opérateur fait basculer vers le haut un portillon supérieur 22 qui s'oppose à tout retrait et qui peut être verrouillé en position fermée par un cadenas latéral du genre de ceux référencés 23 en fig. 2.Each carriage 12 is intended to removably receive a frame 19 which is arranged to accommodate all of the individual tools and equipment of an operator. In the example considered, the frame 19 comprises two superimposed horizontal plates 20 cut out with perforations capable of forming housings for cutting knives and a sharpening steel, these tools being introduced vertically from above; to the two plates 10 is associated a support 21 in the form of a hand, shaped to receive a protective glove with mesh. Once the tools and equipment have been put in place, the operator swings up an upper door 22 which opposes any removal and which can be locked in the closed position by a lateral padlock of the kind of those referenced 23 in FIG. 2.

Il convient d'observer que la traverse horizontale supérieure de chaque cadre porte-outils 19 est pourvue d'un fer-cornière 19a propre à coopérer à coulissement avec le guide 18 de l'un quelconque des chariots 12. On conçoit dans ces conditions qu'une fois garni, chaque cadre 19 est susceptible d'être mis en place sur un chariot 12 du tunnel 1, la rampe 17 s'opposant à tout balancement intempestif.It should be noted that the upper horizontal cross member of each frame tool holder 19 is provided with an angle iron 19 is adapted to cooperate slidingly with the guide 18 of any of the carriages 12. It is conceivable under these conditions that once furnished, each frame 19 is capable of being placed on a carriage 12 of the tunnel 1, the ramp 17 opposing any untimely swaying.

Pour le déplacement horizontal des chariots 12 et leur cheminement à travers le tunnel 1, il est prévu à l'intérieur de chacune des tours 2 et 3 un mécanisme de poussée du genre de celui qui a été représenté en 24 en fig. 4 et 5 et qui correspond à celui qui est monté dans la tour 2. Chaque mécanisme 24 comprend un poussoir horizontal 25 orienté transversalement à la hauteur des fers 10 et pourvu de coulisses longitudinales 26 associées à des guides fixes 27 ; ce poussoir 25 est relié par deux embiellages 28 à un arbre inférieur 29 lui-même attelé par une manivelle 30 à l'organe mobile d'un vérin 31. On comprend que le déplacement de cet organe mobile anime le poussoir 25 d'un mouvement horizontal alternatif.For the horizontal movement of the carriages 12 and their path through the tunnel 1, there is provided inside each of the towers 2 and 3 a pushing mechanism of the kind which has been shown at 24 in FIG. 4 and 5 and which corresponds to that which is mounted in the tower 2. Each mechanism 24 comprises a horizontal pusher 25 oriented transversely to the height of the irons 10 and provided with longitudinal slides 26 associated with fixed guides 27; this pusher 25 is connected by two connecting rods 28 to a lower shaft 29 itself coupled by a crank 30 to the movable member of a jack 31. It is understood that the movement of this movable member animates the pusher 25 with a movement horizontal alternative.

Le mécanisme de poussée 24 logé dans la tour opposée 3 est symétrique à celui qui vient d'être décrit, étant noté qu'il est fixé en place de façon à ce que son poussoir 25 soit disposé à la hauteur des fers 11 (étage inférieur).The pushing mechanism 24 housed in the opposite tower 3 is symmetrical to that which has just been described, it being noted that it is fixed in place so that its pusher 25 is disposed at the height of the irons 11 (lower stage ).

Chacune des tours 2 et 3 est également équipée d'un mécanisme élévateur référencé 32. Tel que représenté en fig. 4 et 6 pour la tour 2, ce mécanisme 32 comprend un coulisseau 33 monté sur deux guides verticaux 34 solidaires du bâti fixe de la tour, lequel coulisseau est solidaire de deux tiges horizontales 35 qui s'étendent en porte-à-faux en étant réunies à leurs extrémités libres par un flasque terminal 36 qui forme un doigt en saillie auquel correspond un prolongement ou doigt équivalent 36' sur le coulisseau. Dans sa partie inférieure, ce dernier est solidaire d'un bout d'axe horizontal 37 qui est relié par un embiellage 38 à l'arbre de sortie d'un moto-réducteur 39, si bien que la rotation de cet arbre dans un sens ou dans l'autre provoque le déplacement vertical (élévation ou abaissement) du coulisseau 33 et de ses tiges 35.Each of the towers 2 and 3 is also equipped with an elevating mechanism referenced 32. As shown in fig. 4 and 6 for tower 2, this mechanism 32 comprises a slide 33 mounted on two vertical guides 34 secured to the fixed frame of the tower, which slide is secured to two horizontal rods 35 which extend in overhang being joined at their free ends by a terminal flange 36 which forms a projecting finger to which corresponds an extension or equivalent finger 36 'on the slide. In its lower part, the latter is integral with a horizontal axis end 37 which is connected by a connecting rod 38 to the output shaft of a geared motor 39, so that the rotation of this shaft in one direction or in the other causes the vertical displacement (raising or lowering) of the slide 33 and its rods 35.

Les faces des doigts 36 et 36' qui sont tournées en vis-à-vis sont pourvues de paires d'ailettes 40, l'écartement des deux ailettes 40 de chaque paire correspondant à la distance verticale séparant les retours horizontaux de chacun des fers 10 ou 11. Par ailleurs, les extrémités de ces fers qui sont disposées à l'aplomb des tours 2 ou 3 pénètrent à l'intérieur de celles-ci et sont équipées de butées éclipsables référencées 41 pour les fers supérieurs 10 et 42 pour les fers inférieurs 11 ; chacune de ces butées 41 ou 42 est constituée par une pièce basculante pourvue d'un contrepoids de rappel qui tend par gravité à maintenir son extrémité antérieure au niveau du fer qui la porte, la disposition dudit contrepoids étant inversée dans les butées 41 et 42, comme illustré en fig. 6.The faces of the fingers 36 and 36 ′ which are turned opposite are provided with pairs of fins 40, the spacing of the two fins 40 of each pair corresponding to the vertical distance separating the horizontal returns from each of the irons 10 or 11. Furthermore, the ends of these irons which are placed vertically above the towers 2 or 3 penetrate inside the latter and are fitted with eclipsable stops referenced 41 for the upper irons 10 and 42 for the irons lower 11; each of these stops 41 or 42 is constituted by a tilting part provided with a return counterweight which tends by gravity to maintain its anterior end at the level of the iron which carries it, the arrangement of said counterweight being reversed in the stops 41 and 42, as illustrated in fig. 6.

Si l'on suppose que lors du fonctionnement de l'un des mécanismes de poussée 24, le coulisseau opposé 33 est à l'arrêt en fin de course à une hauteur telle que ses ailettes 40 se trouvent dans le prolongement des fers 10 ou 11 envisagés, les butées 41 ou 42 de ceux-ci étant éclipsés vers le haut, respectivement vers le bas, par portée des doigts 36 et 36' contre la partie dépassante desdites butées, le chariot 12 qui se trouve en bout des fers concernés est repoussé en direction du coulisseau 33 et les ailettes 40 recueillent les galets 15 du chariot 12 envisagé. Ce dernier est ainsi pris en charge par le coulisseau 33 pour être déplacé verticalement.If it is assumed that during the operation of one of the thrust mechanisms 24, the opposite slide 33 is stopped at the end of the race at a height such that its fins 40 are in the extension of the irons 10 or 11 envisaged, the stops 41 or 42 thereof being eclipsed upwards, respectively downwards, by bearing of the fingers 36 and 36 'against the protruding part of said stops, the carriage 12 which is located at the end of the irons concerned is pushed back in the direction of the slide 33 and the fins 40 collect the rollers 15 of the carriage 12 envisaged. The latter is thus supported by the slide 33 to be moved vertically.

Il va de soi que l'écartement des deux tiges 35 de chaque coulisseau 33 doit être tel que le poussoir 25 de chaque mécanisme 24 puisse passer entre elles pour atteindre le chariot 12 d'extrémité. On conçoit par ailleurs que les deux mécanismes 24 doivent être actionnés en succession, de manière coordonnée vis-à-vis des deux mécanismes élévateurs 32 ; à cet effet, les vérins 31 et les moto-réducteurs 39 sont placés sous la dépendance d'un automate (non représenté), convenablement programmé.It goes without saying that the spacing of the two rods 35 of each slide 33 must be such that the pusher 25 of each mechanism 24 can pass between them to reach the end carriage 12. It will also be understood that the two mechanisms 24 must be actuated in succession, in a coordinated manner with respect to the two lifting mechanisms 32; for this purpose, the jacks 31 and the geared motors 39 are placed under the dependence of an automaton (not shown), suitably programmed.

Au cours du déplacement vertical de chaque coulisseau 33, le cadre porte-outils 19 qui a été pris en charge par ledit coulisseau est soumis, avec les outils et équipements dont il est garni, à une opération efficace de prélavage et de lavage. A cet effet, la tour 2 renferme plusieurs rampes et/ou buses d'aspersion indiquées en 43, 44 et 45 en fig. 7. Ces rampes ou buses sont alimentées par des canalisations indépendantes reliées à des pompes de projection à travers des vannes placées sous la dépendance de l'automate sus-mentionné, et elles sont orientées pour assurer une action efficace vis-à-vis de tel ou tel outil ou équipement supporté par chaque cadre 19.During the vertical movement of each slide 33, the tool holder frame 19 which has been supported by said slide is subjected, with the tools and equipment with which it is provided, to an effective prewash and washing operation. To this end, tower 2 contains several booms and / or spray nozzles indicated in 43, 44 and 45 in fig. 7. These ramps or nozzles are supplied by independent pipes connected to projection pumps through valves placed under the dependence of the aforementioned automaton, and they are oriented to ensure an effective action with respect to such or such tool or equipment supported by each frame 19.

A l'intérieur de la tour 2, l'automate peut impartir au coulisseau 33 correspondant plusieurs déplacements verticaux alternatifs avant évacuation d'un chariot et de son cadre porte-outils. La tour 2 est avantageusement équipée de son propre système de nettoyage interne schématisé en 46 en fig. 1 et 4. En outre le caisson 4 qui est disposé au droit de la tour 2 renferme une rampe 47 pour la projection d'un liquide de rinçage alors que la tour opposée 3 comporte une rampe d'aspersion 48 pour un produit de désinfection.Inside the tower 2, the automaton can impart to the slide 33 corresponding several alternative vertical displacements before evacuation of a carriage and of its tool holder frame. Tower 2 is advantageously equipped with its own internal cleaning system shown schematically at 46 in fig. 1 and 4. In addition, the box 4 which is arranged in line with the tower 2 contains a ramp 47 for spraying a rinsing liquid while the opposite tower 3 comprises a spraying ramp 48 for a disinfection product.

On comprend finalement qu'une fois garnis des outils à nettoyer, les cadres 19 sont disposés par les opérateurs sur les chariots 12 de l'étage inférieur de la machine (fers 11). Quand ce chargement est terminé, la laveuse est mise en fonctionnement, de sorte que sous l'action du mécanisme de poussée 24 de la tour 3, les chariots 12 se déplacent par saccades sur les fers inférieurs 11 pour être successivement introduits dans la tour 2. Chacun d'eux est alors saisi par le coulisseau 33 pour que le cadre porte-outil 19 dont il est muni soit soumis à l'action de pré-lavage et de lavage avant d'être repoussé sur les fers supérieurs 10 par le mécanisme de poussée 24 de la tour 2. A l'étage supérieur, les chariots 12 et les cadres 19 avancent également par saccades et sont rincés par les rampes 47 avant d'être successivement introduits dans la tour 3 où ils sont soumis, lors du mouvement de descente qui leur est imparti par le coulisseau 33 de ladite tour 3, à une opération de stérilisation par la rampe ou buse 48.It is finally understood that once furnished with the tools to be cleaned, the frames 19 are arranged by the operators on the carriages 12 of the lower stage of the machine (irons 11). When this loading is finished, the washer is put into operation, so that under the action of the pushing mechanism 24 of the tower 3, the carriages 12 move by jerks on the lower irons 11 to be successively introduced into the tower 2 Each of them is then gripped by the slide 33 so that the tool-carrying frame 19 with which it is provided is subjected to the pre-washing and washing action before being pushed back onto the upper irons 10 by the mechanism. thrust 24 of the tower 2. On the upper floor, the carriages 12 and the frames 19 also jerk and are rinsed by the ramps 47 before being successively introduced into the tower 3 where they are subjected, during the downward movement which is imparted to them by the slide 33 of said tower 3, to a sterilization operation by the ramp or nozzle 48.

On notera que pendant le cycle de lavage, les portes 8 du tunnel sont fermées, de sorte qu'à l'étage inférieur dudit tunnel, les cadres porte-outils 19 sont maintenus dans une atmosphère stérilisée qui améliore les conditions d'aseptie du nettoyage. Ce n'est que lorsque tous les cadres 19 ont parcouru l'ensemble du trajet ou cycle de nettoyage que la laveuse est arrêtée par l'automate.It will be noted that during the washing cycle, the doors 8 of the tunnel are closed, so that on the lower floor of said tunnel, the tool-carrying frames 19 are maintained in a sterilized atmosphere which improves the aseptic conditions for cleaning. . It is only when all of the frames 19 have covered the entire cleaning path or cycle that the washer is stopped by the machine.

Il va de soi que la machine suivant l'invention est avantageusement équipée de systèmes permettant la récupération et le recyclage de certains au moins des liquides, de dispositifs de filtration, de vannes d'évacuation, etc... qui ne nécessitent aucune description détaillée.It goes without saying that the machine according to the invention is advantageously equipped with systems allowing the recovery and recycling of at least some of the liquids, filtration devices, evacuation valves, etc. which do not require any detailed description. .

On conçoit par ailleurs que l'avance saccadée des chariots 12 dans l'un et l'autre étages du tunnel 1 peut être obtenue, non pas par poussée, mais à l'aide de chaînes ou câbles d'entraînement tendus entre des poulies motrices logées dans les tours 2 et 3.It is also understood that the jerky advance of the carriages 12 in one and the other stages of the tunnel 1 can be obtained, not by pushing, but by means of chains or drive cables stretched between drive pulleys housed in towers 2 and 3.
