Description

La présente invention concerne le ravitaillement d'une machine en éléments rigides ayant la forme de segments de barres ou de bâtonnets.The present invention relates to the supply of a machine with rigid elements in the form of bar or rod segments.

Dans la fabrication des cigarettes, il est nécessaire d'alimenter certaines machines avec des segments de barres cylindriques qui sont des assemblages de filtres comportant trois filtres bout à bout destinés à être sectionnés ultérieurement et incorporés aux cigarettes au moment de l'enrobage de celles-ci dans le papier qui les entoure. Les diverses opérations qu'effectuent ces machines sont largement automatisées mais jusqu'à maintenant certaines opérations continuaient à être effectuées manuellement.In the manufacture of cigarettes, it is necessary to supply certain machines with cylindrical bar segments which are filter assemblies comprising three end-to-end filters intended to be sectioned later and incorporated into cigarettes when they are coated. this in the paper around them. The various operations carried out by these machines are largely automated, but until now certain operations have continued to be carried out manually.

Toutefois, on a constaté que les dispositifs de ravitaillement déjà connus ne présentaient pas toute la souplesse souhaitable dans leur fonctionnement. La présente invention a pour objet un dispositif de ravitaillement d'une machine en éléments rigides ayant la forme de bâtonnets, comprenant une trémie agencée de manière à contenir un empilement de bâtonnets parallèles, un réceptacle mobile destiné à recevoir des emballages contenant chacun un ensemble de bâtonnets ordonnés parallèlement les uns aux autres, ledit réceptacle étant porté par un équipage mobile en hauteur, des moyens d'entraînement du réceptacle capables de le placer au-dessus dudit empilement de bâtonnets, des organes d'actionnement capables d'entraîner ledit équipage mobile de manière qui le réceptacle soit maintenu à une hauteur supérieure à celle de l'empilement et soit amené dans une position de chargement située immédiatement au-dessus de l'empilement quand le niveau de ce dernier atteint une valeur minimale préétablie, un mécanisme de guidage extensible qui est mobile en hauteur pour contenir les bâtonnets dudit empilement et indépendant de l'équipage mobile du réceptacle, des moyens de détection et d'actionnement pour commander une mise en place du réceptacle et assurer la vidange de l'emballage dans la trémie quand le niveau de l'empilement atteint ladite valeur minimale préétablie, et un détecteur de niveau d'empilement solidaire du mécanisme de guidage. Des dispositifs de ce genre sont déjà connus, notamment par la publication de demande anglaise GB-A-2 055 354. Or, dans cette construction connue, le mécanisme de guidage et le réceptacle mobile sont amenés en contact l'un avec l'autre et sont déplacés conjointement l'un par l'autre au moins au cours d'une phase du fonctionnement du dispositif.However, it has been found that the supply devices already known do not have all the flexibility desirable in their operation. The present invention relates to a device for supplying a machine with rigid elements in the form of sticks, comprising a hopper arranged so as to contain a stack of parallel sticks, a movable receptacle intended to receive packages each containing a set of rods ordered parallel to each other, said receptacle being carried by a movable device in height, means for driving the receptacle capable of placing it above said stack of rods, actuating members capable of driving said movable element so that the receptacle is maintained at a height greater than that of the stack and is brought into a loading position located immediately above the stack when the level of the latter reaches a minimum preset value, a guide mechanism extendable which is movable in height to contain the sticks of said stack and independent of the mobile equipment of the ceptacle, detection and actuation means for controlling a positioning of the receptacle and ensuring the emptying of the packaging into the hopper when the level of the stack reaches said predetermined minimum value, and a stack level detector integral with the guide mechanism. Devices of this kind are already known, in particular by the publication of English application GB-A-2 055 354. However, in this known construction, the guide mechanism and the movable receptacle are brought into contact with each other and are moved together by at least one during a phase of operation of the device.

Le présente invention a précisément pour but d'améliorer la souplesse du dispositif en permettant au mécanisme de guidage et au réceptacle de se mouvoir indépendamment l'un de l'autre en effectuant des déplacements qui sont commandés séparément.The present invention specifically aims to improve the flexibility of the device by allowing the guide mechanism and the receptacle to move independently of one another by carrying out movements which are controlled separately.

Pour cela, l'objet de la présente invention est caractérisé en ce que le mécanisme de guidage comporte ses propres moyens d'entraînement qui sont indépendants des organes d'actionnement de l'équipage mobile, en ce que le détecteur solidaire du mécanisme de guidage agit sur les moyens d'entraînement de ce mécanisme de manière à l'amener automatiquement à une hauteur telle qu'il contient l'empilement des bâtonnets dans la trémie jusqu'à son niveau supérieur, et en ce que les organes d'actionnement de l'équipage mobile sont asservis à au moins un autre détecteur de niveau d'empilement des bâtonnets dans la trémie.For this, the object of the present invention is characterized in that the guide mechanism has its own drive means which are independent of the actuating members of the moving element, in that the detector integral with the guide mechanism acts on the drive means of this mechanism so as to automatically bring it to a height such that it contains the stack of sticks in the hopper to its upper level, and in that the actuating members of the mobile equipment are slaved to at least one other level sensor for stacking the sticks in the hopper.

Bien entendu, outre l'application à des bâtonnets constituant des ensembles de filtres destinés à être sectionnés ultérieurement, le dispositif selon l'invention se prête également à des utilisations dans d'autres domaines de la fabrication des cigarettes ou des produits du même genre.Of course, in addition to the application to rods constituting sets of filters intended to be sectioned subsequently, the device according to the invention also lends itself to uses in other fields of the manufacture of cigarettes or products of the same kind.

On va décrire ci-après, à titre d'exemple, une forme de réalisation du dispositif selon l'invention, en se référant au dessin annexé dont:

  • la fig. 1 est une vue générale en perspective,
  • la fig. 2 une vue agrandie des éléments importants, et
  • la fig. 3 est une vue en élévation latérale partielle.
An embodiment of the device according to the invention will be described below, by way of example, with reference to the attached drawing, in which:
  • fig. 1 is a general perspective view,
  • fig. 2 an enlarged view of the important elements, and
  • fig. 3 is a partial side elevation view.

L'installation visible à la fig. 1 comporte une trémie 1 en forme de puits de section horizontale rectangulaire qui débouche à l'entrée d'un canal coudé 2 par lequel des éléments de filtre 3 sont conduits vers l'entrée d'une machine. Ce canal comporte, de façon connue en soi, deux bandes sans fin guidées par des galets entre lesquelles les éléments de filtre 3 sont déplacés. Dans l'exemple décrit ici, ce qu'on appelle éléments de filtre est une pièce rigide de forme cylindrique d'environ 8 cm de longueur et constituée par l'assemblage bout à bout de trois filtres de cigarettes. Dans la machine 4 qui est alimentée par l'installation décrite, ces éléments de filtre sont sectionnés en trois, puis répartis de façon à parvenir dans l'ordre voulu à l'emplacement où ils sont incorporés aux cigarettes. Le canal coudé 2 est représenté entièrement fermé à la fig. 2. Ce dispositif connu en soi n'a pas besoin d'être décrit. Deux brins parallèles des bandes sans fin délimitent entre elles un conduit de quelques centimètres d'épaisseur dans lequel les éléments de filtre rangés parallèlement les uns aux autres sont entraînés en bloc tout en restant parallèles. Un segment initial horizontal 2a du conduit coudé 2 est situé en regard du pied de la trémie 1 et les éléments de filtre qui sont amoncelés à l'intérieur de cette trémie tout en étant arrangés parallèlement les uns aux autres, comme on le verra plus loin, sont entraînés par un courant d'air créé au moyen d'un ventilateur 5 et se déplacent dans le sens de la flèche 6 de façon à entrer dans le conduit 2.The installation visible in fig. 1 comprises a hopper 1 in the form of a well of rectangular horizontal section which opens at the inlet of an elbow channel 2 by which filter elements 3 are led to the inlet of a machine. This channel comprises, in a manner known per se, two endless bands guided by rollers between which the filter elements 3 are moved. In the example described here, what are called filter elements is a rigid piece of cylindrical shape about 8 cm in length and constituted by the end-to-end assembly of three cigarette filters. In the machine 4 which is supplied by the installation described, these filter elements are sectioned in three, then distributed so as to arrive in the desired order at the location where they are incorporated into the cigarettes. The bent channel 2 is shown fully closed in FIG. 2. This device known per se need not be described. Two parallel strands of the endless bands delimit between them a conduit a few centimeters thick in which the filter elements arranged parallel to each other are driven as a block while remaining parallel. A horizontal initial segment 2a of the bent conduit 2 is located opposite the base of the hopper 1 and the filter elements which are stacked inside this hopper while being arranged parallel to each other, as will be seen below. , are entrained by a current of air created by means of a fan 5 and move in the direction of the arrow 6 so as to enter the duct 2.

L'agencement de la trémie 1 et de ses dispositifs accessoires, est conçu de façon à simplifier l'introduction des éléments de filtre dans la trémie, tout en maintenant leur alignement et sans qu'ils subissent de chocs. Ces éléments de filtre sontfabriqués dans une installation particulière et pour les besoins de l'organisation de la production, ils sont ensuite emballés dans des cartons 36 en forme de parallélépipède dont la largeur correspond à la longueur des éléments de filtre. Le dispositif représenté à la fig. 2 comporte un réceptacle désigné de façon générale par 7 dont la pièce principale est un plateau 8 qui est normalement disposé dans une position légèrement inclinée vers le bas de façon que les cartons 36 ouverts sur leur côté étroite supérieure puissent être placés commodément sur le réceptacle 7 tout en étant retenu par les rebords 8a prévus à cet effet. En outre, les emballages sont fixés au plateau 8 par une ventouse 37, comme on le verra plus loin.The arrangement of the hopper 1 and its accessory devices is designed so as to simplify the introduction of the filter elements into the hopper, while maintaining their alignment and without them being subjected to shocks. These filter elements are manufactured in a particular installation and for the needs of the organization of production, they are then packed in cartons 36 in the shape of a parallelepiped whose width corresponds to the length of the filter elements. The device shown in fig. 2 comprises a receptacle generally designated by 7, the main part of which is a plate 8 which is normally disposed in a slightly inclined downward position so that the cartons 36 open on their upper narrow side can be placed conveniently on the receptacle 7 while being retained by the flanges 8a provided for this purpose. In addition, the packages are fixed to the plate 8 by a suction cup 37, as will be seen below.

Selon l'invention, le dispositif de ravitaillement comporte des agencements qui ont pour but d'amener le réceptacle 7 a une hauteur qui correspond à celle atteinte par l'accumulation des éléments de filtre déjà contenus dans la trémie, de renverser l'emballage de façon qu'il soit disposé sens dessus dessous à l'intérieur même de la trémie, et de le déplacer vers le haut progressivement afin qu'il se vide, les éléments de filtres se répartissant sur toute la surface de la trémie en restant parallèles les uns aux autres. De plus, le dispositif comporte des moyens qui observent le niveau supérieur de l'amoncellement des éléments de filtre dans la trémie au fur-et-à- mesure qu'il baisse par évacuation des éléments dans le canal 2 à la base de la trémie et qui, au moment voulu, commandent le fonctionnement du réceptacle 7 afin qu'il vienne se placer dans la position correcte et opère le renversement de l'emballage, comme indiqué ci-dessus.According to the invention, the refueling device has arrangements which aim to bring the receptacle 7 to a height which corresponds to that reached by the accumulation of the filter elements already contained in the hopper, to reverse the packaging of so that it is placed upside down inside the hopper itself, and move it upwards gradually so that it empties, the filter elements being distributed over the entire surface of the hopper while remaining parallel to each other. In addition, the device includes means which observe the upper level of the accumulation of the filter elements in the hopper as it drops by evacuation of the elements in the channel 2 at the base of the hopper. and which, at the desired time, control the operation of the receptacle 7 so that it comes to be placed in the correct position and operates the overturning of the packaging, as indicated above.

Pour cela, comme on le voit à la fig. 2, la trémie 1 ne comporte pas de paroi latérale frontale sur son côté antérieur. En effet, elle est constituée par une pièce de tôle coudée en forme de U disposée verticalement et formant le fond vertical 9 et les deux côtés latéraux 10 et 11 qui sont munis de deux fentes verticales 12 et 13 dont le rôle sera expliqué plus loin.For this, as seen in fig. 2, the hopper 1 does not have a front side wall on its front side. Indeed, it is constituted by a piece of bent U-shaped sheet metal arranged vertically and forming the vertical bottom 9 and the two lateral sides 10 and 11 which are provided with two vertical slots 12 and 13 whose role will be explained below.

Sur son côté frontal antérieur, la trémie 1 est partiellement fermée par une paroi extensible constituée par un écran 14 dont le bord supérieur horizontal est lié à un cadre 15 entournant tout le profil de la trémie 1. Cet écran est constitué dans l'exemple décrit par une feuille de matière souple qui passe à la base de la trémie sur un rouleau 16 et qui s'enroule sur une bobine 17. Cette bobine peut être équipée d'un dispositif à ressort qui tend constamment à enrouler l'écran et par conséquent à déplacer le cadre 15 vers le bas. Toutefois, ce même cadre 15 est connecté à des moyens d'entraînement qui commandent ses déplacements. Ainsi, le montant vertical 18 situé derrière la trémie et muni d'une coulisse de guidage 19, constitue un rail permettant aux moyens d'entraînement du cadre 15 de déplacer ce dernier de haut en bas ou de bas en haut. La constitution exacte de ces moyens d'entraînement n'est pas représentée au dessin. On peut prévoir par exemple un vérin ou une tige filetée logée à l'intérieur du montant 18 et guidant un écrou solidaire du cadre 15. En variante, on peut prévoir des moyens d'entraînement tels qu'un câble formant une boucle fermée sur elle-même et accrochée à des poulies disposées en haut et en bas du montant 18.On its front front side, the hopper 1 is partially closed by an extendable wall constituted by a screen 14 whose horizontal upper edge is linked to a frame 15 surrounding the entire profile of the hopper 1. This screen is constituted in the example described by a sheet of flexible material which passes at the base of the hopper on a roller 16 and which is wound on a reel 17. This reel can be equipped with a spring device which constantly tends to wind the screen and consequently to move the frame 15 down. However, this same frame 15 is connected to drive means which control its movements. Thus, the vertical upright 18 located behind the hopper and provided with a guide slide 19, constitutes a rail allowing the drive means of the frame 15 to move the latter from top to bottom or from bottom to top. The exact constitution of these drive means is not shown in the drawing. One can provide for example a jack or a threaded rod housed inside the upright 18 and guiding a nut integral with the frame 15. Alternatively, one can provide drive means such as a cable forming a closed loop on it - even and hung on pulleys arranged at the top and bottom of the upright 18.

Le cadre 15 porte un détecteur 20 qui est constitué d'une cellule photosensible disposée en regard de la fente 13 et d'une source de lumière (non représentée) placée sur l'autre petit côté du cadre 15 et capable d'émettre un faisceau lumineux horizontal passant à travers les fentes 12 et 13 de façon à agir sur la cellule photosensible. Cette dernière peut être une photorésistance, une cellule photoélectrique ou tout autre type d'élément sensible au rayonnement électromagnétique et capable d'émettre un signal électronique sous l'effet d'un tel rayonnement. Les signaux émis par le détecteur 20 sont conduits à un dispositif de commande dont certains éléments sont représentés à la fig. 1 et qui assure la programmation du fonctionnement automatique du dispositif de ravitaillement comme on le verra plus loin.The frame 15 carries a detector 20 which consists of a photosensitive cell arranged opposite the slot 13 and a light source (not shown) placed on the other short side of the frame 15 and capable of emitting a beam horizontal light passing through the slots 12 and 13 so as to act on the photosensitive cell. The latter can be a photoresistor, a photoelectric cell or any other type of element sensitive to electromagnetic radiation and capable of emitting an electronic signal under the effect of such radiation. The signals emitted by the detector 20 are led to a control device, certain elements of which are shown in FIG. 1 and which ensures the programming of the automatic operation of the refueling device as will be seen below.

Le bâti 21 du dispositif décrit est constitué par un ensemble de barres formant une structure rigide qui maintient en place la trémie 1 ainsi que le montant 18. Ce bâti 21 maintient également en place deux montants de guidage verticaux 22 et 23 ainsi qu'une tige filetée d'entraînement 24 qui est disposée parallèlement au montant 22 et au voisinage de celui-ci et dont l'extrémité inférieure est liée à un engrenage de renvoi 25 de sorte que cette tige 24 peut être entraînée en rotation à partir d'un arbre rotatif horizontal 26 entraîné par un moteur (non représenté). Deux manchons de guidage 27 montés, l'un sur le montant 22, et l'autre sur le montant 23, sont reliés rigidement par une barre transversale 28 qui passe derrière la trémie 1, ce qui constitue un équipage mobile. Sur la barre 28 est fixé un écrou 29 qui, comme on le voit à la fig. 2 se trouve au voisinage du manchon 27 et est engagé sur la tige filetée 24, de sorte que la rotation de cette tige dans un sens ou dans l'autre, fait monter ou descendre l'équipage mobile constitué par les manchons 27 et la barre de liaison 28. Des consoles 30 qui s'étendent de part et d'autre de la trémie 1 vers l'avant, à partir des deux extrémités de la barre 28, portent des paliers 31 qui guident un arbre rotatif 32 commandé par un moteur à réducteur 33. Le bâti de ce moteur est aussi solidaire de l'équipage mobile (27, 28) qui porte le réceptacle 7. Comme on le voit à la fig. 2, l'arbre 32 porte et commande le réceptacle 7 dont les moyens d'entraînement sont donc entièrement différents de ceux du détecteur 20, une cellule 43 analogue à la cellule 20 commande les déplacements de l'équipage mobile 27, 28.The frame 21 of the device described consists of a set of bars forming a rigid structure which keeps the hopper 1 in place as well as the upright 18. This frame 21 also keeps in place two vertical guide uprights 22 and 23 as well as a rod drive thread 24 which is arranged parallel to and in the vicinity of the upright 22 and the lower end of which is linked to a return gear 25 so that this rod 24 can be driven in rotation from a shaft horizontal rotary 26 driven by a motor (not shown). Two guide sleeves 27 mounted, one on the upright 22, and the other on the upright 23, are rigidly connected by a transverse bar 28 which passes behind the hopper 1, which constitutes a mobile assembly. On the bar 28 is fixed a nut 29 which, as seen in FIG. 2 is located in the vicinity of the sleeve 27 and is engaged on the threaded rod 24, so that the rotation of this rod in one direction or the other, causes the mobile assembly constituted by the sleeves 27 and the bar to go up or down. of connection 28. Consoles 30 which extend on either side of the hopper 1 forwards, from the two ends of the bar 28, carry bearings 31 which guide a rotary shaft 32 controlled by a motor with reducer 33. The frame of this motor is also integral with the movable assembly (27, 28) which carries the receptacle 7. As can be seen in FIG. 2, the shaft 32 carries and controls the receptacle 7, the drive means of which are therefore entirely different from those of the detector 20, a cell 43 similar to the cell 20 controls the movements of the mobile assembly 27, 28.

A la fig. 3, on voit un des paliers 31 monté sur une console 30. Le réceptacle 7 est représenté simultanément dans sa position abaissée et dans sa position relevée. La plaque de support 8 pourvue des rebords 8a est fixée sur un cadre de support 34 formé de deux barres profilées parallèles reliées par des plaques d'extrémité. Ce cadre 34 est lui-même fixé par l'intermédiaire d'oeillets 35 à l'arbre 32. L'emballage 36, placé sur le plateau 8, peut être fermé par un obturateur 38. Cet obturateur coulissant 38 est constitué par une plaque de tôle allongée portée par deux coulisseaux 39 engagés l'un et l'autre sur des barres cylindriques rigides 40 solidaires d'étriers 41 fixés au cadre 34.In fig. 3, we see one of the bearings 31 mounted on a console 30. The receptacle 7 is shown simultaneously in its lowered position and in its raised position. The support plate 8 provided with the flanges 8a is fixed to a support frame 34 formed by two parallel profiled bars connected by end plates. This frame 34 is itself fixed by means of eyelets 35 to the shaft 32. The packaging 36, placed on the plate 8, can be closed by a shutter 38. This sliding shutter 38 is constituted by a elongated sheet metal plate carried by two slides 39 engaged one and the other on rigid cylindrical bars 40 integral with stirrups 41 fixed to the frame 34.

Par rotation de l'arbre 32, le réceptacle 7 peut passer de la position abaissée dans laquelle le plateau 8 est disposé de façon que l'on puisse facilement poser sur lui un emballage 36 contenant des éléments de filtre 3 arrangés parallèlement à l'épaisseur de l'emballage, à une position élevée dans laquelle l'emballage 36 est entièrement renversé et se trouve à l'intérieur de la trémie 1. La ventouse 37 maintient l'emballage 36 en place. Pour commander la libération des éléments de filtre au moment voulu, le cadre 34 porte à ses deux extrémités des moyens de guidage et de commande de l'obturateur coulissant 38. Comme moyen de commande, on prévoit de préférence un petit vérin (non représenté) monté sur l'un des étriers 41 et capable de déplacer l'obturateur 38 de la position ouverte dans laquelle il se trouve représenté à la partie inférieure gauche de la fig. 3, à la position fermée dans laquelle il est représenté à la partie supérieure de la même figure.By rotation of the shaft 32, the receptacle 7 can pass from the lowered position in which the plate 8 is arranged so that one can easily place on it a package 36 containing filter elements 3 arranged parallel to the thickness of the package, to an elevated position in which the package 36 is completely inverted and is inside the hopper 1. The suction cup 37 holds the package 36 in place. To control the release of the filter elements at the desired time, the frame 34 carries at its two ends means for guiding and controlling the sliding shutter 38. As control means, a small cylinder is preferably provided (not shown) mounted on one of the stirrups 41 and capable of moving the shutter 38 from the open position in which it is shown in the lower left part of FIG. 3, in the closed position in which it is shown in the upper part of the same figure.

Le dispositif décrit peut fonctionner de façon automatique tout en gardant une grande souplesse dans son mode d'opération.The device described can operate automatically while retaining great flexibility in its operating mode.

En effet, les moyens de commande pilotés par le détecteur 20 peuvent être ajustés et réglés de façon à fonctionner de différentes façons.Indeed, the control means controlled by the detector 20 can be adjusted and adjusted so as to operate in different ways.

On peut prévoir, par exemple, le fontionnement suivant: Tant que la cellule 20 est impressionnée par le rayon lumineux provenant de la source lumineuse disposée en regard de la cellule sur l'autre côté de la trémie, les moyens d'entraînement du cadre 15 sont commandés de façon à faire descendre ce dernier lentement le long de la trémie. En revanche, dès que ce rayon lumineux est interrompu par l'empilage des éléments de filtre dans la trémie, les moyens d'entraînement sont commandés de façon à faire remonter, par exemple par étapes, le cadre 15 le long de la trémie. Ainsi, le cadre 15 et, par conséquent le bord supérieur de l'écran 14 suivent le haut de l'empilage des éléments de filtre au fur-et-à- mesure que sa hauteur diminue, et lors du rechargement, ils s'élèvent jusqu'à atteindre le nouveau niveau supérieur de l'empilage.One can provide, for example, the following operation: As long as the cell 20 is impressed by the light ray coming from the light source placed opposite the cell on the other side of the hopper, the frame drive means 15 are controlled so as to lower the latter slowly along the hopper. On the other hand, as soon as this light ray is interrupted by the stacking of the filter elements in the hopper, the drive means are controlled so as to raise, for example in stages, the frame 15 along the hopper. Thus, the frame 15 and, consequently the upper edge of the screen 14 follow the top of the stack of the filter elements as its height decreases, and when reloading, they rise until reaching the new upper level of stacking.

Quant au réceptacle 7, son fonctionnement sera piloté par le détecteur 43, mais différemment: Normalement, le réceptacle est maintenu à une hauteur moyenne et dans la position de la fig. 1, c'est-à-dire la position abaissée de façon à pouvoir être chargé d'un emballage 36 à n'importe quel moment convenable.As for the receptacle 7, its operation will be controlled by the detector 43, but differently: Normally, the receptacle is maintained at an average height and in the position of FIG. 1, that is to say the position lowered so that it can be loaded with a package 36 at any convenient time.

Cependant, une butée 42, prévue sur la trémie 1 à une hauteur correspondant au niveau minimum que l'empilage des éléments de filtre doit atteindre, provoquera l'émission d'un signal lorsque le cadre 15 atteindra cette butée. Sous l'effet de ce signal, le moteur à réducteur 33 sera enclenché de façon à faire pivoter le réceptacle de la position abaissée à la position élevée tout en amenant l'obturateur 38 en position d'obturation au cours de ce mouvement. L'emballage 36 sera alors maintenu par la ventouse 37 et l'empilage des éléments de filtres contenus dans cet emballage sera supporté par l'obturateur 38. Le signal donné par l'arrivée du cadre 15 à la hauteur de la butée inférieure 42 enclenchera outre le basculement du plateau 8, la mise en route des moyens d'entraînement du réceptacle, c'est-à-dire la mise en route du moteur entraînant l'arbre 26. Le réceptacle affectuera donc un déplacement vers le bas qui sera arrêté lorsque l'emballage 36 se présentera avec son bord inférieur immédiatement au-dessus de l'empilage des éléments de filtres dans la trémie. A ce moment, les moyens de commande de l'obturateur 38 seront mis en route de façon à libérer le contenu de l'emballage 36 qui tombera dans la trémie sans que l'empilage perde son orientation horizontale et perpendiculaire à l'axe de pivotement du réceptacle. Il est évident que le rayon lumineux pilotant le détecteur 20 sera alors obturé, ce qui aura pour effet de faire monter le cadre 15 pas à pas comme on l'a vu précédemment. Au cours de cette opération, les moyens d'entraînement du réceptacle seront couplés aux moyens d'entraînement du cadre 15 afin que l'équipage mobile 27, 28 se déplace vers le haut en précédant le cadre 15. Le réceptacle mobile 7 sera alors commandé de façon à se trouver à chaque instant à une hauteur prédéterminée par rapport au cadre 15 et par conséquent au détecteur 20.However, a stop 42, provided on the hopper 1 at a height corresponding to the minimum level that the stack of filter elements must reach, will cause the emission of a signal when the frame 15 reaches this stop. Under the effect of this signal, the gear motor 33 will be started so as to pivot the receptacle from the lowered position to the raised position while bringing the shutter 38 to the closed position during this movement. The packaging 36 will then be held by the suction cup 37 and the stacking of the filter elements contained in this packaging will be supported by the shutter 38. The signal given by the arrival of the frame 15 at the height of the lower stop 42 will engage in addition to the tilting of the plate 8, the starting of the means for driving the receptacle, that is to say the starting of the motor driving the shaft 26. The receptacle will therefore affect a downward movement which will be stopped when the package 36 is presented with its lower edge immediately above the stack of the filter elements in the hopper. At this time, the shutter control means 38 will be started so as to release the contents of the package 36 which will fall into the hopper without the stack losing its horizontal orientation and perpendicular to the pivot axis of the receptacle. It is obvious that the light ray driving the detector 20 will then be closed, which will have the effect of raising the frame 15 step by step as we have seen previously. During this operation, the drive means of the receptacle will be coupled to the drive means of the frame 15 so that the movable element 27, 28 moves upwards preceding the frame 15. The movable receptacle 7 will then be controlled so as to be at all times at a predetermined height relative to the frame 15 and therefore to the detector 20.

Dès que ce dernier sera parvenu au-dessus de l'empilage des éléments contenus dans la trémie, son mouvement ascendant cessera et il commencera à suivre cet empilage dans son mouvement progressif vers le bas. Le couplage entre le déplacement du réceptacle et celui du détecteur sera alors interrompu, le réceptacle revenant se placer dans la position initiale représentée à la fig. 1. Une fois cette position atteinte, on peut encore prévoir de commander l'éjection de l'emballage 36 vide par exemple en connectant la ventouse 37 à une source d'air comprimé au lieu qu'elle soit connectée comme normalement à une source de vide.As soon as the latter has reached above the stack of elements contained in the hopper, its upward movement will cease and it will begin to follow this stacking in its progressive downward movement. The coupling between the movement of the receptacle and that of the detector will then be interrupted, the receptacle returning to place in the initial position shown in FIG. 1. Once this position has been reached, provision can also be made to control the ejection of the empty package 36, for example by connecting the suction cup 37 to a source of compressed air instead of being connected as normal to a source of compressed air. empty.
