Description

La présente invention a pour objet un mélangeur avec bol amovible et support de bol comprenant un écran mobile de protection.The present invention relates to a mixer with removable bowl and bowl support comprising a movable protective screen.

Dans différentes industries telles que la boulange­rie, pâtisserie, ou plus généralement l'agro-ali­mentaire, il existe des mélangeurs comprenant un bâti, lui-même composé d'une tête et d'un corps, la tête étant orientée à 90° par rapport au corps de façon que l'axe de l'outil soit vertical. Le corps assure généralement la stabilité de l'ensemble, et comprend la motorisation tandis que la tête joue le rôle de transmission de la force motrice à l'outil. La matière à travailler est généralement contenue dans un bol amovible qui vient se loger dans un support de bol de façon que la face ouverte du bol soit dans un plan horizontal. Par ailleurs, le support de bol est relié à un dispositif monte et baisse permettant d'amener le bol amovible et donc la matière qu'il contient, à hauteur de l'outil de façon que cette matière puisse être travaillée par cet outil. Le système monte et baisse comprend généralement deux colonnes orientées verticalement et toutes deux solidaires du support de bol, l'une au moins de ces deux colonnes pouvant être entraî­née en translation suivant son axe longitudinal par un dispositif adéquat à caractère irréversible en position de travail tel que vis à bille, crémail­lère et pignon, ou tout simplement came et levier de manoeuvre.In different industries such as baking, pastry, or more generally the food industry, there are mixers comprising a frame, itself composed of a head and a body, the head being oriented at 90 ° relative to to the body so that the axis of the tool is vertical. The body generally ensures the stability of the assembly, and includes the motorization while the head plays the role of transmitting the driving force to the tool. The material to be worked is generally contained in a removable bowl which is housed in a bowl support so that the open face of the bowl is in a horizontal plane. Furthermore, the bowl support is connected to an up and down device making it possible to bring the removable bowl and therefore the material it contains, up to the tool so that this material can be worked by this tool. The up and down system generally comprises two columns oriented vertically and both integral with the bowl support, at least one of these two columns being able to be driven in translation along its longitudinal axis by an appropriate device of irreversible nature in the working position such than ball screw, rack and pinion, or simply cam and operating lever.

Dans ce type de mélangeur il existe donc une pos­sibilité d'accès au bol par l'utilisateur à tout instant puisque le bol ne vient pas au contact de la tête et celle-ci est généralement de dimensions inférieures à celles du bol. Un tel dispositif pourrait donc présenter un danger pour l'utilisa­teur compte tenu de cette possibilité d'introduc­tion entre l'outil et le bol, par exemple de la main de l'utilisateur. De plus, un élément exté­rieur au mélangeur peut venir se loger entre la tête et le bol, ce qui entraînerait des dégrada­tions du mélangeur.In this type of mixer there is therefore a possibility of access to the bowl by the user at any time since the bowl does not come into contact with the head and the latter is generally of dimensions smaller than those of the bowl. Such a device could therefore present a danger to the user taking into account this possibility of introduction between the tool and the bowl, for example by the hand of the user. In addition, an element external to the mixer can be housed between the head and the bowl, which would cause damage to the mixer.

Aussi, ces mélangeurs sont munis d'un écran mobile de protection destiné à interdire l'accès au bol durant la phase de travail de l'outil.Also, these mixers are provided with a mobile protective screen intended to prevent access to the bowl during the working phase of the tool.

Différents types d'écran sont connus selon qu'ils sont escamotables par dessus la tête par pivotement autour d'un axe horizontal de la même façon qu'une visière ou qu'ils sont pivotants autour d'un axe orienté verticalement de façon à être rabattu autour de la tête du mélangeur. Ces écrans sont généralement des grilles métalliques.Different types of screen are known depending on whether they are retractable over the head by pivoting about a horizontal axis in the same way as a visor or whether they are pivotable around an axis oriented vertically so as to be folded around the mixer head. These screens are generally metallic grids.

De plus, ces écrans mobiles sont munis de disposi­tifs de sécurité comprenant généralement un contac­teur qui arrête la machine ou empêche son fonction­nement lorsque l'écran est en position ouverte.In addition, these mobile screens are provided with safety devices generally comprising a contactor which stops the machine or prevents its operation when the screen is in the open position.

De tels écrans assurent bien la protection recher­chée mais ils présentent un certain nombre d'incon­vénients et notamment celui de nécessiter une manipulation particulière et indépendante qui n'est effectuée qu'après la préparation complète du mélangeur.Such screens do provide the desired protection, but they have a certain number of drawbacks and in particular that of requiring a specific and independent manipulation which is only carried out after the complete preparation of the mixer.

La présente invention a pour but de proposer un mélangeur avec écran mobile de protection dont la mise en place est automatique et simultanée à la mise en position de travail du bol amovible, l'écran interdisant tout fonctionnement de ce mélangeur lorsqu'il n'est pas en place, dont la mise en place se fait en temps masqué et dont l'écran assure la totale protection de l'ouverture du bol amovible et supprime les organes de sécurité électriques spécifiques à l'écran.The object of the present invention is to propose a mixer with a mobile protective screen, the installation of which is automatic and simultaneous with the placing in the working position of the removable bowl, the screen prohibiting any operation of this mixer when it is not not in place, whose installation is done in masked time and whose the screen provides total protection of the removable bowl opening and removes the specific electrical safety devices on the screen.

A cet effet, le mélangeur comprend un bol amovible, un support de bol, une tête avec notamment un pla­teau porte-outil sur lequel est monté un outil, un corps comprenant un dispositif monte et baisse du support de bol, constitué d'au moins une colonne orientée verticalement et solidaire du support de bol et d'un mécanisme d'entraînement en transla­tion de cette colonne entre deux positions haute et basse suivant son axe longitudinal, ainsi qu'un écran mobile de protection et se caractérise en ce que cet écran est mobile en translation ou en rotation autour d'un axe entre une position fermée et une position ouverte et en ce que cet écran est relié à cette colonne par des moyens d'entraînement de façon que les positions haute et basse de cette colonne correspondent respectivement à des posi­tions fermée et ouverte de l'écran.For this purpose, the mixer comprises a removable bowl, a bowl support, a head with in particular a tool-holder plate on which a tool is mounted, a body comprising a device for raising and lowering the bowl support, consisting of at least a column oriented vertically and integral with the bowl support and a drive mechanism in translation of this column between two high and low positions along its longitudinal axis, as well as a movable protective screen and is characterized in that this screen is movable in translation or in rotation about an axis between a closed position and an open position and in that this screen is connected to this column by drive means so that the high and low positions of this column correspond respectively to closed and open positions of the screen.

Selon une autre caractéristique, le mélangeur comprend un écran ayant au moins une tige montée coulissante par rapport à la tête et orientée parallèlement à la colonne du dispositif monte et baisse.According to another characteristic, the mixer comprises a screen having at least one rod mounted to slide relative to the head and oriented parallel to the column of the device rises and falls.

Selon une variante de l'invention, le mélangeur comprend deux colonnes et un écran à deux tiges et se caractérise en ce qu'il comprend deux barres transversales qui relient les colonnes entre elles et les tiges entre elles et en ce que les extrémi­tés du levier sont montées coulissantes par rapport à ces deux barres transversales.According to a variant of the invention, the mixer comprises two columns and a screen with two rods and is characterized in that it comprises two transverse bars which connect the columns to one another and the rods to each other and that the ends of the lever are slidably mounted relative to these two transverse bars.

Sur la figure 1 on a représenté un mélangeur 10 comprenant un corps 12 et une tête 14, la tête 14 étant disposée à 90° de l'axe longitudinal du corps 12. Sur cette figure 1 on a également représenté un dispositif monte et baisse 16, un écran mobile 18 ainsi qu'un bol amovible 20 reposant sur le support de bol 22.In Figure 1 there is shown a mixer 10 comprising a body 12 and a head 14, the head 14 being disposed at 90 ° to the longitudinal axis of the body 12. In this Figure 1 there is also shown a device for raising and lowering 16 , a movable screen 18 and a removable bowl 20 resting on the bowl support 22.

Le corps 12 du mélangeur 10, tronqué sur le dessin repose généralement sur le sol. A l'intérieur du corps est prévu le dispositif monte et baisse 16 qui comprend deux colonnes 24 mobiles en transla­tion suivant leur axe longitudinal 26 par coulisse­ment à travers la tête. Le mécanisme d'entraînement en translation proprement dit de ces colonnes selon leur axe longitudinal comprend deux biellettes 28 et 30 articulées entre elles par une de leurs extrémités, la seconde extrémité de la biellette 28 étant solidaire d'un levier de manoeuvre 32, monté rotatif par rapport à un axe perpendiculaire au plan comprenant la biellette tandis que la seconde extrémité de la biellette 30 est montée pivotante sur la colonne 24 autour d'un axe perpendiculaire au plan contenant cette même biellette 30.The body 12 of the mixer 10, truncated in the drawing generally rests on the ground. Inside the body is provided the up and down device 16 which comprises two columns 24 movable in translation along their longitudinal axis 26 by sliding through the head. The drive in translation proper of these columns along their longitudinal axis comprises two links 28 and 30 hinged together at one of their ends, the second end of the link 28 being secured to an operating lever 32, mounted to rotate relative to an axis perpendicular to the plane comprising the link while the second end of the link 30 is pivotally mounted on the column 24 around an axis perpendicular to the plane containing this same rod 30.

Ces colonnes 24 sont solidaires du support de bol 22 par leur extrémité inférieure de façon à entraî­ner ce support de bol durant leur translation suivant les axes 26.These columns 24 are integral with the bowl support 22 by their lower end so as to drive this bowl support during their translation along the axes 26.

Par ailleurs, il est prévu un détecteur de position 34 comprenant une pièce de commande 36 destinée à coopérer avec le logement 38 ménagé sur la colonne, la position de ce logement 38 sur la colonne 24 étant telle que le mélangeur ne puisse fonctionner que lorsque cette colonne 24 est en position haute et que la pièce de commande 36 coopère avec le logement 38.Furthermore, a position detector 34 is provided comprising a control part 36 intended to cooperate with the housing 38 formed on the column, the position of this housing 38 on the column 24 being such that the mixer can only operate when this column 24 is in the high position and the control piece 36 cooperates with the housing 38.

La tête 14 du mélangeur qui joue le rôle de renvoi d'angle et qui reçoit la force motrice générée par les moteurs d'entraînement généralement disposés dans le corps du mélangeur, comprend un arbre moteur (non figuré) destiné à entraîner un plateau porte-outil 40, lui-même supportant un dispositif planétaire 42 de manière à conférer à l'outil 44 un mouvement épicycloïdal. La tête 14 supporte égale­ment l'écran de protection 18 qui comprend une grille de protection 46 constituée par exemple d'un treillis soudé, et de deux tiges 48 solidaires du treillis dont la partie supérieure est orientée verticalement et parallèlement aux colonnes 24. Ces tiges 48 sont montées coulissantes à travers la tête 14. Les extrémités des deux colonnes 24 et des deux tiges 48 sont munies chacune d'un ergot 50 faisant saillie et qui coopère avec des trous oblongs 52 ménagés dans des leviers 54 qui relient l'ergot d'une tige 48 à l'ergot d'une colonne 24, l'axe de pivotement 56 de ces leviers 54 étant orienté perpendiculairement au plan contenant les couples tige-colonne.The head 14 of the mixer which plays the role of angle transmission and which receives the motive force generated by the drive motors generally arranged in the body of the mixer, comprises a motor shaft (not shown) intended to drive a carrier plate tool 40, itself supporting a planetary device 42 so as to give the tool 44 an epicyclic movement. The head 14 also supports the protective screen 18 which comprises a protective grid 46 consisting for example of a welded mesh, and two rods 48 integral with the mesh, the upper part of which is oriented vertically and parallel to the columns 24. These rods 48 are slidably mounted across the head 14. The ends of the two columns 24 and the two rods 48 are each provided with a protruding lug 50 which cooperates with oblong holes 52 formed in levers 54 which connect the lug of a rod 48 to the lug of a column 24, the pivot axis 56 of these levers 54 being oriented perpendicular to the plane containing the stem-column pairs.

Sur la figure 2 on a représenté un mélangeur iden­tique à celui de la figure 1 en position de travail dans laquelle l'outil de travail 44 est entraîné en rotation par le plateau porte-outil 40 tandis que l'écran a été abaissé dans le sens de la flèche 58 simultanément au mouvement du bol dans la direction de la flèche 60 et que le levier 32 a été actionné dans le sens de la flèche 62.FIG. 2 shows a mixer identical to that of FIG. 1 in the working position in which the working tool 44 is driven in rotation by the tool-holder plate 40 while the screen has been lowered in the direction arrow 58 simultaneously with the movement of the bowl in the direction of arrow 60 and that the lever 32 has been actuated in the direction of arrow 62.

Le contacteur 36 est alors dans une position telle que le mélangeur puisse fonctionner. Chaque levier 54 a pivoté autour de son axe de rotation.The contactor 36 is then in a position such that the mixer can operate. Each lever 54 has pivoted about its axis of rotation.

Sur la figure 3 on a représenté un mélangeur 10 identique au mélangeur précédent comprenant des colonnes 24 et des tiges 48. Néanmoins, dans cette variante les deux colonnes 24 et les deux tiges 48 sont reliées entre elles par des barres transver­sales 64 et 66 disposées sensiblement à l'extrémité supérieure de ces colonnes et tiges, un levier unique 68 étant monté pivotant autour d'un arbre 70 dont l'axe longitudinal est confondu avec l'axe 56, le levier 68 ayant ses extrémités montées coulis­santes libres à travers les barres transversales 64 et 66.FIG. 3 shows a mixer 10 identical to the previous mixer comprising columns 24 and rods 48. However, in this variant the two columns 24 and the two rods 48 are connected together by transverse bars 64 and 66 arranged substantially at the upper end of these columns and rods, a single lever 68 being pivotally mounted around a shaft 70 whose longitudinal axis coincides with axis 56, the lever 68 having its ends mounted free sliding through the bars 64 and 66.

Dans cette variante également l'écran a été modifié dans le sens où en lieu et place du treillis pro­posé aux figures 1 et 2, cet écran comprend main­ tenant une plaque de forme sensiblement en tronc de cône, non ajouré de façon a assurer une certaine herméticité de l'ensemble durant la phase de tra­vail.In this variant also the screen has been modified in the sense that instead of the trellis proposed in FIGS. 1 and 2, this screen includes hand holding a plate of substantially truncated cone shape, not perforated so as to ensure a certain hermeticity of the assembly during the working phase.

Sur la figure 4, on a représenté une variante de levier 72 à double fourche emboîté entre deux barres transversales 74, 76 reliant les colonnes 24 et les tiges 48.FIG. 4 shows a variant of a lever 72 with a double fork nested between two transverse bars 74, 76 connecting the columns 24 and the rods 48.

Les branches du levier 72 comprennent à leurs extrémités des logements 78 pour permettre l'em­boîtement, la profondeur de ces logements étant suffisante pour compenser les variations de dis­tance entre les barres transversales sans désenga­gement.The arms of the lever 72 include at their ends recesses 78 to allow nesting, the depth of these recesses being sufficient to compensate for the variations in distance between the transverse bars without disengagement.

Sur la figure 5, on a représenté une variante de liaison du levier 72 avec les barres transversales 74, 76, dans laquelle les branches du levier sont fixées à ces barres transversales au moyen de liaisons souples du type silent-bloc 80.In FIG. 5, a variant of connection of the lever 72 with the transverse bars 74, 76 is shown, in which the arms of the lever are fixed to these transverse bars by means of flexible connections of the silent-block type 80.

Le fonctionnement d'un tel mélangeur est main­tenant décrit en regard des figures 1 et 2.The operation of such a mixer is now described with reference to FIGS. 1 and 2.

En position de repos telle que représentée à la figure 1 le levier 32 est généralement orienté vers l'arrière de telle sorte que les colonnes 24 sont en position basse, ce qui amène donc également le support de bol 22 en position basse. Le bol 20 peut être disposé sur le support de bol après avoir pris la précaution d'introduire l'outil 44 dans le bol par son ouverture supérieure.In the rest position as shown in Figure 1 the lever 32 is generally oriented towards the rear so that the columns 24 are in the low position, which therefore also brings the bowl support 22 in the low position. The bowl 20 can be placed on the bowl support after taking the precaution of introducing the tool 44 into the bowl through its upper opening.

Lorsque les colonnes 24 sont en position basse, le levier 54 dont l'axe de pivotement est disposé entre ces colonnes 24 et les tiges 48 provoque la montée de ces mêmes tiges en position haute, ces tiges entraînant le treillis constituant l'écran vers le haut. Dans l'exemple représenté, la forme tronc de cône de cet écran lui permet de venir à proximité de la partie inférieure de la tête par sa petite base tandis que sa grande base est située sensiblement à hauteur du dispositif planétaire 42. Ainsi en position de repos, le dispositif plané­taire 42 et son outil 44 restent accessibles puis­que l'écran est escamoté en partie supérieure.When the columns 24 are in the low position, the lever 54 whose pivot axis is arranged between these columns 24 and the rods 48 causes the same rods to rise in the high position, these rods driving the trellis constituting the screen to the top. In the example shown, the truncated cone shape of this screen allows it to come close to the lower part of the head by its small base while its large base is located substantially at the height of the planetary device 42. Thus in the position of rest, the planetary device 42 and its tool 44 remain accessible since the screen is retracted in the upper part.

Si l'on se reporte à la figure 2, le levier 32 ayant été actionné dans le sens de la flèche 62, les deux biellettes 28 et 30 convertissent ce mouvement de rotation du levier en une translation des colonnes 24 ce qui a pour triple fonction de remettre en circuit le détecteur de position 34, de monter le support de bol et le bol donc la matière qu'il contient, à hauteur de l'outil afin que cette matière soit travaillée et enfin, de provoquer simultanément l'abaissement de l'écran 18 par mouvement de translation des tiges 48 inverse au mouvement de translation des colonnes 24. Le détecteur de position 34 ne permet la mise en marche du mélangeur que lorsque le logement 38 arrive à hauteur de la pièce de commande 36 ce qui correspond à un mouvement de l'écran tel que sa grande base vient à proximité immédiate de l'ouver­ture supérieure du bol 20.Referring to FIG. 2, the lever 32 having been actuated in the direction of the arrow 62, the two links 28 and 30 convert this movement of rotation of the lever into a translation of the columns 24 which has a triple function to reconnect the position detector 34, to mount the bowl support and the bowl, therefore the material it contains, at the height of the tool so that this material is worked and finally, to simultaneously cause the lowering of the screen 18 by translational movement of the rods 48 opposite to the translational movement of the columns 24. The position detector 34 does not allow the mixer to be started until the housing 38 reaches the control part 36, which corresponds to a movement of the screen such that its large base comes close to the upper opening of the bowl 20.

Le déplacement en translation dans des sens op­posés des colonnes 24 et des tiges 48 est obtenu par le fait que l'axe de pivotement 56 est disposé entre les colonnes et les tiges. Les trous oblongs 52 permettent donc au levier 54 de coulisser par rapport aux ergots 50 ce qui permet par ailleurs de compenser les variations de distance entre les ergots 50 des tiges et ceux des colonnes 24.The translational movement in opposite directions of the columns 24 and the rods 48 is obtained by the fact that the pivot axis 56 is disposed between the columns and the rods. The oblong holes 52 therefore allow the lever 54 to slide relative to the lugs 50, which moreover makes it possible to compensate for the variations in distance between the lugs 50 of the rods and those of the columns 24.

Le fonctionnement des variantes représentées aux figures 3, 4 et 5 est identique, le levier unique et la double barre transversale, ou la fourche, pouvant se révéler utiles dans certains modes de réalisation de mélangeurs au sein desquels l'im­plantation de deux leviers latéraux s'avère impos­sible. Dans cette variante, le rattrapage des variations de distance qui sépare les deux barres transversales est assuré par le coulissement du levier à travers ces mêmes barres transversales ou par des liaisons souples.The operation of the variants represented in FIGS. 3, 4 and 5 is identical, the single lever and the double transverse bar, or the fork, being able to prove to be useful in certain embodiments of mixers within which the implantation of two lateral levers s turns out to be impossible. In this variant, it is possible to compensate for the variations in distance which separates the two transverse bars by sliding the lever through these same transverse bars or by flexible connections.

Il est également possible de prévoir une variante dans laquelle l'écran a le profil de la tête et des dimensions supérieures de façon à venir en position escamotée autour de cette tête.It is also possible to provide a variant in which the screen has the profile of the head and of larger dimensions so as to come into the retracted position around this head.

Sur les figures 6 et 7, on a également représenté deux variantes de réalisation de l'écran mobile.In FIGS. 6 and 7, two alternative embodiments of the mobile screen have also been shown.

Sur la figure 6, l'écran 18 est mobile en rotation autour d'un axe vertical 82 confondu avec l'axe de rotation du plateau porte-outil. De plus, il com­prend une ouverture d'accès 83.In Figure 6, the screen 18 is movable in rotation about a vertical axis 82 coincident with the axis of rotation of the tool holder plate. In addition, it includes an access opening 83.

Chaque colonne 24 porte une crémaillère 84 qui coopère avec un pignon 86 solidaire d'un arbre 88, orienté perpendiculairement à la colonne, sur lequel est fixée une poulie 90. Dans la variante à deux colonnes représentée il est prévu deux poulies 90 et 92 qui sont entraînées dans le même sens de façon synchrone par les crémaillères des colonnes. Un câble 93 relie les deux poulies entre elles et ce câble est solidaire de l'écran de façon telle qu'il passe autour de l'axe de rotation 82.Each column 24 carries a rack 84 which cooperates with a pinion 86 integral with a shaft 88, oriented perpendicular to the column, on which is fixed a pulley 90. In the variant with two columns shown, two pulleys 90 and 92 are provided which are driven in the same direction synchronously by the column racks. A cable 93 connects the two pulleys together and this cable is integral with the screen so that it passes around the axis of rotation 82.

Par ailleurs, le câble est enroulé dans un sens sur la première poulie et dans le sens opposé sur la seconde.Furthermore, the cable is wound in one direction on the first pulley and in the opposite direction on the second.

Le fonctionnement est le suivant : lorsque le dispositif monte et baisse est actionné, les colon­nes 24 montent ce qui provoque la rotation des deux poulies, le câble s'enroule alors sur l'une et se déroule sur l'autre provoquant la rotation de l'écran sur lui-même autour de l'axe 82 sensible­ment d'un demi-tour. Le bol monte et l'ouverture d'accès 83 en position frontale à l'arrêt se trouve orientée vers le bâti du mélangeur qui empêche l'accès.The operation is as follows: when the device rises and falls is actuated, the columns 24 rise which causes the rotation of the two pulleys, the cable then winds up on one and unwinds on the other causing the rotation of the screen on itself around the axis 82 substantially a half-turn. The bowl rises and the access opening 83 in the frontal position when stopped is oriented towards the frame of the mixer which prevents access.

Sur la figure 7, l'écran de protection 18 est complété par un écran fixe 94. L'écran 18 est mobile par rapport à un axe horizontal perpendicu­laire à la colonne 24. Un premier pignon 96 est solidaire du levier de manoeuvre 32 du mécanisme d'entraînement.In FIG. 7, the protective screen 18 is completed by a fixed screen 94. The screen 18 is movable relative to a horizontal axis perpendicular to the column 24. A first pinion 96 is integral with the operating lever 32 of the mechanism drive.

L'écran mobile 18 comprend deux tiges dont les extrémités en partie supérieure sont montées rota­tives par rapport à la tête du mélangeur. L'une des tiges est solidaire d'un second pignon 98 relié au premier par une chaîne 100.The movable screen 18 comprises two rods, the ends of which at the top are rotatably mounted relative to the head of the mixer. One of the rods is integral with a second pinion 98 connected to the first by a chain 100.

Le fonctionnement de cette variante est le sui­vant : lorsque le levier de manoeuvre 32 est ac­tionné, il met en rotation le premier pignon qui entraîne en rotation le second pignon par la chaîne 100. La tige 97 effectue une rotation par rapport à son extrémité. Les différents rapports d'entraîne­ment sont tels que l'écran mobile 18 complète la partie fixe 94 de façon à assurer une continuité de l'écran, au moment où le bol est en position haute.The operation of this variant is as follows: when the operating lever 32 is actuated, it rotates the first pinion which rotates the second pinion by the chain 100. The rod 97 rotates relative to its end. The various drive ratios are such that the movable screen 18 completes the fixed part 94 so as to ensure continuity of the screen, when the bowl is in the high position.

Le pignon 96 peut également être solidaire d'un au­tre pignon coaxial (non représenté) entraîné par une crémaillère portée par la colonne 24.The pinion 96 can also be integral with another coaxial pinion (not shown) driven by a rack carried by the column 24.

Un tel mélangeur muni de cet écran mobile de sécu­rité permet la mise en place automatique de cet écran en position au dessus du bol amovible. On comprend par ailleurs, que le fonctionnement du mélangeur est rendu impossible tant que l'écran n'est pas parfaitement mis en place. Il est totale­ment impossible d'accéder au détecteur de position pour le bloquer de façon artificielle; quant aux corps étrangers tels que poussière, graisse, huile, farine et autres, ils ne peuvent entraver le bon fonctionnement du détecteur de position.Such a mixer provided with this mobile safety screen allows the automatic positioning of this screen in position above the removable bowl. We also understand that the operation of the mixer is made impossible until the screen is not perfectly in place. It is completely impossible to access the position detector to block it artificially; as for foreign bodies such as dust, grease, oil, flour and others, they cannot hinder the proper functioning of the position detector.

Les liaisons entre l'écran, les colonnes, le sup­port de bol étant mécaniques seule la non montée du support de bol empêche la descente de l'écran, mais dans ce cas le mélangeur ne peut pas fonctionner.The connections between the screen, the columns, the bowl support being mechanical only the non-mounted bowl support prevents the screen from lowering, but in this case the mixer cannot operate.

L'utilisateur n'a pas à se soucier de la mise en place de cet écran puisque celle-ci est automatique et qu'elle se fait par la manoeuvre du levier de commande de montée du bol, opération dans tous les cas nécessaire.The user does not have to worry about the setting up of this screen since it is automatic and is done by the operation of the bowl rise control lever, operation in any case necessary.
