Description

Broyeur ou concasseur à marteaux ou analogue muni  Hammer crusher or crusher or the like provided therewith
d'un dispositif d'extraction du rotor  a rotor extraction device
La présente invention concerne le domaine du traitement de matériaux de toutes origines, en particulier par déchiquetage au moyen de concasseurs ou de broyeurs à marteaux, ou analogues et a pour objet un broyeur ou concasseur ou analogue muni d'un dispositif d'extraction du rotor. The present invention relates to the field of the treatment of materials of all origins, in particular by shredding using crushers or hammer mills, or the like, and relates to a crusher or crusher or the like provided with a rotor extraction device .
La récupération de produits métalliques à partir d'objets hors d'usage, en particulier de véhicules automobiles, au moyen de concasseurs ou de broyeurs, s'effectue généralement par introduction des objets dans un broyeur à marteaux, par l'intermédiaire d'une rampe d'introduction équipée d'un tambour écraseur ; ledit broyeur à marteaux arrache et déchiquette la matière y entrant, par interaction avec une ou plusieurs enclumes, qui éjectent et/ou évacuent à travers des parois criblantes les déchets mécaniques obtenus présentant un calibre déterminé. Ces déchets sont ensuite traités en vue d'une élimination des matières impropres à la réutilisation et d'un tri des matières restantes en fonction de leurs caractéristiques métallurgiques.  The recovery of metal products from spent objects, especially motor vehicles, by crushers or grinders, is generally carried out by introducing the objects into a hammer mill, via a introduction ramp equipped with a crushing drum; said hammer mill tears and shreds the material entering, by interaction with one or more anvils, which eject and / or discharge through screen walls mechanical waste obtained having a given size. This waste is then treated for disposal of unsuitable materials for reuse and sorting of the remaining materials according to their metallurgical characteristics.
Les broyeurs à marteaux connus à ce jour, dont les marteaux sont généralement montés sur un rotor constitué par un assemblage de disques et sont éclipsables dans le rotor, permettent, généralement, un broyage correct des produits suivant une densité prédéterminée.  The hammer mills known to date, whose hammers are generally mounted on a rotor constituted by a disk assembly and are eclipsable in the rotor, allow, generally, a correct grinding of the products to a predetermined density.
Ces broyeurs connus sont généralement sous forme d'unités de dimension plus ou moins importante, en fonction de leur rendement journalier et présentent un dispositif d'entraînement du rotor en prise directe avec ce dernier ou par l'intermédiaire d'un ensemble de transmission à poulies et courroies ou à pignons et chaînes, à vitesse unique ou à variateur de fréquence, éventuellement avec interposition d'un coupleur hydraulique destiné à favoriser le démarrage et à protéger les parties mécaniques et électriques en cas de surcharge ou de blocage. Par ailleurs, pour permettre un accès à l'intérieur de l'enceinte de broyage, le carter de celle-ci est généralement constitué par des demi-coquilles pouvant être déployées de part et d'autre de l'axe longitudinal du rotor.  These known mills are generally in the form of units of greater or lesser size, depending on their daily efficiency and have a drive device of the rotor in direct contact with the latter or via a transmission assembly. pulleys and belts or gears and chains, single speed or variable frequency, possibly with the interposition of a hydraulic coupler intended to promote starting and to protect the mechanical and electrical parts in case of overload or blockage. Furthermore, to allow access to the interior of the grinding chamber, the housing thereof is generally constituted by half-shells can be deployed on either side of the longitudinal axis of the rotor.
Cependant, si les broyeurs existant satisfont aux différents cahiers des charges concernant leurs performances, il se pose un problème lié à l'extraction du rotor en vue de travaux de maintenance. En effet, il est extrêmement difficile, voire impossible, de réaliser cette extraction sans un démontage d'une partie importante de la machine, ce qui entraîne des frais d'interventions correspondants très élevés. En outre, il est absolument nécessaire de mettre en ouvre un engin de levage de forte puissance, tel qu'une grue, ce qui entraîne encore l'inconvénient supplémentaire de disposer d'un espace au sol suffisamment important. However, if the existing shredders meet the various specifications concerning their performance, there is a problem related to the extraction of the rotor for maintenance work. Indeed, it is extremely difficult, if not impossible, to perform this extraction without disassembly of a large part of the machine, resulting in very high corresponding intervention costs. In addition, it is absolutely necessary to implement a high-powered lifting device, such as a crane, which still entails the additional disadvantage of having a sufficiently large floor space.
Il existe, par conséquent, une demande pour une solution permettant d'intervenir rapidement et simplement sur le rotor du broyeur ou concasseur ou dans l'enceinte de broyage, par prévision d'une manutention dudit rotor préférentiellement sans mise enouvre de moyen extérieur.  There is, therefore, a demand for a solution allowing to intervene quickly and simply on the rotor of the crusher or crusher or in the crushing chamber, by predicting a handling of said rotor preferably without setting out of external means.
Par le document GB-A-2 178 675, on connaît déjà un broyeur ou concasseur essentiellement constitué par un rotor ou moyen de réduction dimensionnelle par broyage, par concassage, par déchiquetage ou par grignotage, par un châssis de support de l'ensemble ou carter du broyeur et par un capot de protection recouvrant l'ensemble et renfermant une enceinte de broyage munie de parois criblantes.  GB-A-2 178 675 already discloses a crusher or crusher essentially consisting of a rotor or means of dimensional reduction by grinding, crushing, shredding or nibbling, by a support frame of the assembly or crusher housing and a protective cover covering the assembly and enclosing a grinding chamber provided with screening walls.
Le dispositif d'extraction du rotor proposé par ce document réalise une extraction par soulèvement, est associé au capot pivotant, sur lequel il est monté pivotant, et utilise le même organe de maraeuvre (vérin) que celui déplaçant ledit capot.  The extraction device of the rotor proposed by this document carries out extraction by lifting, is associated with the pivoting cover, on which it is pivotally mounted, and uses the same maraeuvre member (cylinder) that moving said cover.
F -A-2 326 234 a pour objet un broyeur ou concasseur à rotor extractible, avec un châssis fixe et un capot mobile.  F -A-2 326 234 relates to an extractable rotor crusher or crusher, with a fixed frame and a movable cowl.
Selon ce document, le rotor peut, si nécessaire, être solidarisé au capot (monté pivotant sur le châssis) en vue de son extraction par soulèvement.  According to this document, the rotor may, if necessary, be secured to the hood (pivotally mounted on the frame) for extraction by lifting.
US-A-1 602 622 concerne également un broyeur ou concasseur à rotor extractible, avec un châssis fixe et un capot mobile. L'extraction du rotor est réalisée en plusieurs phases, savoir démontage de la partie supérieure du palier, soulèvement du rotor au moyen d'un moyen d'accrochage solidaire du capot monté pivotant et, enfin, dépose et évacuation du rotor sur des rails support.  US-A-1 602 622 also relates to an extractable rotor crusher or crusher, with a fixed frame and a movable cover. The extraction of the rotor is carried out in several phases, namely disassembly of the upper part of the bearing, lifting of the rotor by means of a fastening means integral with the pivotally mounted cover and, finally, removal and evacuation of the rotor on support rails .
Le soulèvement du capot, en vue de son pivotement et du soulèvement du rotor, est réalisé par un moyen de levage externe.  The lifting of the hood, for its pivoting and the lifting of the rotor, is performed by an external lifting means.
Les solutions proposées par ces documents antérieurs sont donc relativement complexes structurellement et opérationnellement, et associent systématiquement le capot, directement ou indirectement, à l'extraction du rotor. Ce dernier doit donc être équipé des moyens adéquats et présenter une structure renforcée en conséquence. The solutions proposed by these prior documents are therefore relatively complex structurally and operationally, and systematically associate the hood, directly or indirectly, with the extraction of the rotor. The latter must therefore be equipped with adequate means and have a reinforced structure accordingly.
La présente invention vise notamment à surmonter ces limitations  The present invention aims in particular to overcome these limitations
A cet effet, l'invention a pour objet un broyeur ou concasseur ou analogue du type précité, caractérisé en ce qu'il est muni d'un dispositif d'extraction du rotor consistant en des moyens de montage pivotant des extrémités du rotor sur le châssis du broyeur, du concasseur ou analogue.  For this purpose, the invention relates to a crusher or crusher or the like of the aforementioned type, characterized in that it is provided with a device for extracting the rotor consisting of pivotally mounting means of the ends of the rotor on the frame of the crusher, crusher or the like.
L'invention sera mieux comprise, grâce à la description ci- après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :  The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
la figure 1 est une vue en élévation latérale d'un broyeur muni d'un dispositif d'extraction du rotor conforme à l'invention, en position de service du rotor, l'enceinte de broyage étant ouverte (les équipements annexes, notamment d'alimentation, d'évacuation et d'entraînement n'étant pas représentés) ;  FIG. 1 is a side elevational view of a mill provided with a device for extracting the rotor according to the invention, in the operating position of the rotor, the grinding chamber being open (ancillary equipment, in particular feeding, evacuation and training are not shown);
la figure 2 est une vue analogue à celle de la figure 1 représentant le rotor extrait, en position de maintenance ;  Figure 2 is a view similar to that of Figure 1 showing the extracted rotor in the maintenance position;
les figures 3 et 4 sont des vues en perspective selon deux directions différentes de l'objet représenté figure 2 ;  Figures 3 and 4 are perspective views in two different directions of the object shown in Figure 2;
les figures 5 à 7 sont des vues en perspective illustrant les moyens du dispositif d'extraction du rotor (le capot et le rotor étant enlevés), en position d'extraction du rotor (figures 5 et 6) et en position de travail du rotor (figure 7), et,  FIGS. 5 to 7 are perspective views illustrating the means of the rotor extraction device (the hood and the rotor being removed), in the rotor extraction position (FIGS. 5 and 6) and in the rotor working position; (Figure 7), and,
la figure 8 est une vue similaire à celle de la figure 3, le capot étant d'une seule pièce.  Figure 8 is a view similar to that of Figure 3, the cover being in one piece.
Les figures 1 à 4 et 8 des dessins annexés représentent, à titre d'exemples, un broyeur ou concasseur à marteaux 1 ou analogue, qui est essentiellement constitué par un rotor 1 ou moyen de réduction dimensionnelle par broyage, par concassage, par déchiquetage ou par grignotage, par un châssis 2 de support de l'ensemble ou carter du broyeur et par un capot de protection, d'un seul tenant ou sous forme de deux demi- coquilles 3 recouvrant l'ensemble et renfermant une enceinte de broyage munie de parois criblantes.  Figures 1 to 4 and 8 of the accompanying drawings show, by way of example, a hammer crusher or crusher 1 or the like, which essentially consists of a rotor 1 or means of dimensional reduction by grinding, crushing, shredding or by nibbling, by a support frame 2 of the assembly or crusher housing and by a protective cover, in one piece or in the form of two half-shells 3 covering the assembly and enclosing a grinding chamber provided with screens.
Le rotor 1 ou moyen de réduction dimensionnelle du broyeur ou concasseur est entraîné par un dispositif d'entraînement, qui est essentiellement constitué par un moyen de transmission, sous forme d'une boîte de vitesse (non représentée) reliée à l'arbre du rotor 1, ou par un moteur hydraulique relié directement à l'arbre dudit rotor 1, le moyen d'entraînement ainsi constitué étant relié de manière déconnectable à l'arbre du rotor 1 , sans démontage total du châssis du broyeur. En outre, le rotor 1 est, de manière connue, monté à chaque extrémité dans un palier 4 du châssis 2. The rotor 1 or dimensional reduction means of the crusher or crusher is driven by a drive device, which is essentially consisting of a transmission means, in the form of a gearbox (not shown) connected to the rotor shaft 1, or by a hydraulic motor connected directly to the shaft of said rotor 1, the drive means and formed being disconnectably connected to the rotor shaft 1, without total disassembly of the frame of the mill. In addition, the rotor 1 is, in known manner, mounted at each end in a bearing 4 of the frame 2.
Conformément à l'invention, le broyeur ou concasseur ou analogue est muni d'un dispositif 5 d'extraction du rotor 1 consistant en des moyens de montage pivotant des extrémités du rotor 1 sur le châssis 2 du broyeur, du concasseur ou analogue.  According to the invention, the mill or crusher or the like is provided with a device 5 for extracting the rotor 1 consisting of pivoting mounting means of the ends of the rotor 1 on the frame 2 of the mill, the crusher or the like.
Comme cela ressort de manière évidente des figures 1 à 8, le pivotement du rotor 1 s'effectue latéralement et autour d'axes de pivotement 7 mutuellement alignés selon une direction parallèle à l'axe du rotor 1, en position de travail et l'extraction.  As is evident from FIGS. 1 to 8, the pivoting of the rotor 1 takes place laterally and around pivoting axes 7 mutually aligned in a direction parallel to the axis of the rotor 1, in the working position and extraction.
En outre, le dégagement latéral du rotor 1, autorisé par l'écartement préalable du capot 3, est avantageusement réalisé par un mouvement de petite ampleur, ne nécessitant pas de débordement en dehors de l'enceinte du broyeur ou concasseur. Dans la pratique, des bras de montage 2' ou analogues ou des parties du châssis 2 peuvent être reliés, de manière articulée en pivotement, latéralement aux supports 6 ou directement aux paliers 4. Ces bras 2' ou analogues peuvent être eux-mêmes montés articulés sur le châssis 2, par exemple par une seconde liaison pivotante.  In addition, the lateral clearance of the rotor 1, authorized by the prior separation of the cover 3, is advantageously achieved by a small-scale movement, requiring no overflow outside the enclosure of the mill or crusher. In practice, mounting arms 2 'or the like or parts of the frame 2 can be pivotably connected laterally to the supports 6 or directly to the bearings 4. These arms 2' or the like can themselves be mounted articulated on the frame 2, for example by a second pivoting connection.
Ainsi, l'extraction du rotor 1 est réalisée très simplement par un mouvement de pivotement par rapport au châssis 2 et ce dernier le supporte donc aussi bien en position de travail (figure 1) qu'en position d'extraction (figures 2 à 4 et 8).  Thus, the extraction of the rotor 1 is made very simply by a pivoting movement relative to the frame 2 and the latter thus supports it both in the working position (Figure 1) and in the extraction position (Figures 2 to 4 and 8).
Le capot 3, quant à lui, n'intervient pas dans l'extraction du rotor et ne doit par conséquent pas être adapté ou pourvu de moyens adaptés pour une telle extraction.  The cover 3, meanwhile, does not intervene in the extraction of the rotor and must therefore not be adapted or provided with suitable means for such extraction.
En accord avec une caractéristique de l'invention, le dispositif d'extraction 5 comprend un ou des organes 8 spécifique(s) assurant le déplacement du rotor 1, par pivotement par rapport au châssis 2, entre sa position de travail et sa position d'extraction.  According to a feature of the invention, the extraction device 5 comprises one or more specific members 8 ensuring the displacement of the rotor 1, by pivoting relative to the frame 2, between its working position and its position. 'extraction.
Ainsi, le mouvement d'extraction et de retour en position de travail du rotor 1 peut être effectué indépendamment de tout autre mouvement de parties constitutives du broyeur ou concasseur, et sans faire appel à un autre moyen. Thus, the movement of extraction and return to working position of the rotor 1 can be performed independently of any other movement of constituent parts of the crusher or crusher, and without using any other means.
Le dispositif d'extraction 8 peut soit ne comporter qu'un seul vérin 8, soit présenter un vérin 8 associé à chaque ensemble axe 7 / support 6.  The extraction device 8 may have only one cylinder 8, or have a cylinder 8 associated with each axis 7 / support 6.
Comme l'illustrent les dessins des figures annexées, le dispositif d'extraction 5 est indépendant et séparé du capot 3 ou des deux demi-coquilles 3 formant le capot, les déplacements du rotor 1 entre sa position de travail et sa position d'extraction et le déplacement du capot 3 ou des deux demi-coquilles 3 du capot étant indépendants entre eux.  As illustrated by the drawings of the appended figures, the extraction device 5 is independent and separate from the cover 3 or the two half-shells 3 forming the cover, the movements of the rotor 1 between its working position and its extraction position and the displacement of the cover 3 or the two half-shells 3 of the cover being independent of each other.
De manière préférée, les moyens de montage pivotant des extrémités du rotor 1 sur le châssis 2 constituant le dispositif d'extraction 5 se présentent, pour chaque extrémité de rotor, préférentiellement, comme le montrent les figures 1 à 8 des dessins annexés, sous forme d'un support 6 du palier 4, relié audit palier 4 et monté à articulation, au moyen d'un axe de pivotement 7 au châssis 2 du broyeur, concasseur ou analogue, ce support 6 étant relié, à distance de l'axe de pivotement 7, à la tige d'un vérin 8, dont la chape s'appuie sur le châssis 2.  Preferably, the means for pivotally mounting the ends of the rotor 1 on the frame 2 constituting the extraction device 5 are, for each rotor end, preferably, as shown in FIGS. 1 to 8 of the accompanying drawings, in the form of a support 6 of the bearing 4, connected to said bearing 4 and mounted to articulation, by means of a pivot axis 7 to the frame 2 of the mill, crusher or the like, the support 6 being connected, at a distance from the axis of pivoting 7, to the rod of a jack 8, whose yoke is supported on the frame 2.
Ainsi, il est possible, après ouverture de l'enceinte de broyage par pivotement du capot 3 ou des demi-coquilles 3 la délimitant en coopération avec le châssis 2, de dégager, dans un premier temps, le rotor 1 et ses supports 6 de paliers 4, puis par actionnement du ou de chacun des vérins 8 de faire effectuer un pivotement au rotor 1 autour des axes de pivotement 7 alignés des supports 6 opposés, de manière à l'amener de sa position de travail représentée à la figure 1 à une position d'extraction représentée à la figure 2.  Thus, it is possible, after opening the grinding chamber by pivoting the cover 3 or the half-shells 3 delimiting it in cooperation with the frame 2, to release, in a first step, the rotor 1 and its supports 6 of bearings 4, then by actuating the or each of the cylinders 8 to rotate the rotor 1 about the aligned pivot axes 7 of the opposed supports 6, so as to bring it from its working position shown in Figure 1 to an extraction position shown in Figure 2.
Bien entendu, préalablement à l'ouverture des demi-coquilles, dans une position telle que représentée à la figure 1 des dessins annexés, le ou les moteurs d'entraînement ou moyens de transmission, connectés sur l'arbre du rotor 1, seront déconnectés de manière à permettre le basculement ultérieur du rotor dans sa position d'extraction. Une telle déconnexion de l'arbre du rotor 1 et du ou des moteurs d'entraînement ou du ou des moyens de transmission sera avantageusement réalisée, de manière connue, par prévision d'une liaison entre lesdits moteurs ou moyens de transmission et l'arbre du rotor du type à clavette ou à cannelures, permettant un montage et un démontage par simple coulissement longitudinal. Il s'ensuit qu'un démontage complexe des moyens d'entraînement peut être évité. Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, chaque palier 4 de support du rotor 1 peut, quand sa constitution le permet, être monté directement de manière pivotable autour d'un axe d'articulation, sur le châssis 2 du broyeur, concasseur ou analogue et être actionné directement par un vérin 8 correspondant. Of course, prior to the opening of the half-shells, in a position as shown in Figure 1 of the accompanying drawings, the drive or transmission means, connected to the rotor shaft 1, will be disconnected so as to allow the subsequent tilting of the rotor in its extraction position. Such disconnection of the rotor shaft 1 and the drive motor or the transmission means or means will advantageously be carried out, in a known manner, by predicting a connection between said motors or transmission means and the shaft key or spline type rotor, allowing assembly and disassembly by simple longitudinal sliding. As a result, complex disassembly of the drive means can be avoided. According to an alternative embodiment of the invention, not shown in the accompanying drawings, each support bearing 4 of the rotor 1 can, when its constitution allows it, be mounted directly pivotally about a hinge axis, on the frame 2 of the crusher, crusher or the like and be actuated directly by a cylinder 8 corresponding.
Le pivotement dans la position d'extraction s'effectue, dans un tel cas, de manière tout à fait identique à celle décrite à propos du mode de réalisation selon les figures 1 à 8.  The pivoting in the extraction position takes place, in such a case, in exactly the same manner as described with respect to the embodiment according to FIGS. 1 to 8.
L'homme du métier comprend à la lecture de la présente que le principe de l'invention, à savoir réaliser une extraction du rotor 1 par simple pivotement sur le seul châssis 2 indépendamment du capot 3 et avec des moyens d'actionnement 8 propres, peut s'appliquer à diverses structures de support et de guidage en rotation du rotor 1 , pour autant que ces structures puissent être déplacées par basculement par rapport au châssis 2, de telle manière que l'accès au rotor 1 et au fond intérieur dudit châssis 2 (formant la partie inférieure de la chambre de broyage) soit possible en vue de la maintenance ou du remplacement de pièces.  The person skilled in the art understands, on reading this, that the principle of the invention, namely to achieve an extraction of the rotor 1 by simple pivoting on the single frame 2 independently of the cover 3 and with own actuating means 8, can be applied to various structures for supporting and guiding rotation of the rotor 1, provided that these structures can be displaced by tilting relative to the frame 2, so that access to the rotor 1 and the inner bottom of said frame 2 (forming the lower part of the grinding chamber) is possible for the maintenance or replacement of parts.
Dans les exemples illustrés schématiquement et pour visualiser les fonctions réalisées et la structure générale du dispositif 5, les supports de paliers 6 reposent à plat sur des parois opposées du châssis 2 en position de travail du rotor 1 (en étant calés latéralement), mais bien entendu d'autres modes de montage sont possibles avec éventuel blocage en position par emboîtement, ou venue en prise ou analogue.  In the examples illustrated schematically and to visualize the functions performed and the general structure of the device 5, the bearing supports 6 lie flat on opposite walls of the frame 2 in the working position of the rotor 1 (being wedged laterally), but other modes of assembly are possible with possible locking in position by interlocking, or engaged or the like.
Selon une caractéristique de l'invention, le support 6 de palier 4 ou le palier 4 est préférentiellement pourvu d'un moyen de verrouillage en position de service (non représentée) qui peut être sous forme d'un verrou mécanique à actionnement par vérin, monté sur le châssis 2 du broyeur, concasseur ou analogue. Il est également possible de réaliser un tel verrouillage par mise en ouvre d'un vérin d'actionnement 7 de type autobloquant. Ainsi, lorsqu'une extraction du rotor 1 doit être effectuée, il est nécessaire de réaliser une suite d'opérations consistant en un déverrouillage préalable de la position de service, puis en un actionnement en pivotement du rotor 1. Bien entendu, ces opérations seront avantageusement réalisées de manière automatique, c'est-à-dire que la commande de l'extraction entraînera automatiquement un déverrouillage préalable au pivotement du rotor 1. Grâce à l'invention, il est possible de réaliser une extraction rapide et simple d'un rotor de broyeurs, concasseurs ou analogues, ce sans mettre enoawre de dispositif complexe et lourd de manutention, intégré au broyeur ou concasseur ou séparé, et sans nécessiter d'opération de démontage longue et onéreuse. Ceci est plus particulièrement possible également du fait que les moyens d'entraînement, à savoir directement par moteur ou par une transmission intermédiaire peuvent être montés en extrémité de l'arbre du rotor, de manière facilement et rapidement déconnectable. According to a characteristic of the invention, the support 6 of bearing 4 or the bearing 4 is preferably provided with a locking means in the operating position (not shown) which can be in the form of a mechanical lock actuated by jack, mounted on the frame 2 of the crusher, crusher or the like. It is also possible to achieve such locking by implementation of an actuating jack 7 of the self-locking type. Thus, when an extraction of the rotor 1 is to be performed, it is necessary to carry out a sequence of operations consisting of a prior unlocking of the operating position, then a pivotal actuation of the rotor 1. Of course, these operations will be advantageously performed automatically, that is to say that the control of the extraction will automatically unlock before the pivoting of the rotor 1. Thanks to the invention, it is possible to achieve a quick and simple removal of a rotor mills, crushers or the like, without putting enoawre complex and heavy handling device, integrated mill or crusher or separated, and without requiring disassembly operation long and expensive. This is particularly possible also because the drive means, namely directly by motor or by an intermediate transmission can be mounted at the end of the rotor shaft, easily and quickly disconnectable.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
