Description

La présente invention se rapporte à un dispositif de déversement dans un réceptacle, d'objets plats en particulier de plis en sortie d'une machine de tri dans laquelle les plis sont acheminés disposés verticalement dans des godets et libérés au-dessus du dispositif.The present invention relates to a device for pouring into a receptacle, flat objects in particular folds out of a sorting machine in which the folds are routed arranged vertically in buckets and released above the device.

Plus précisément, dans une telle machine de tri, chaque pli dont la destination a été préalablement reconnue, est disposé verticalement dans un godet. Les godets sont acheminés selon un carrousel et leur fond est ouvert au-dessus de la sortie adéquate pour libérer chaque pli. A cette sortie, les plis sont empilés à plat ou rangés sur chant dans un bac mobile ou dans une case fixe.More specifically, in such a sorting machine, each fold whose destination has been previously recognized, is arranged vertically in a bucket. The buckets are conveyed in a carousel and their bottom is open above the appropriate outlet to release each fold. At this exit, the folds are stacked flat or stored on edge in a mobile bin or in a fixed box.

De manière générale, les plis sont empilés à plat dans des bacs. Or ces sorties sont particulièrement encombrantes.Generally, the folds are stacked flat in trays. These outputs are particularly bulky.

Les bacs en sortie doivent être dimensionnés conformément aux dimensions maximales des plis traités.The output bins must be dimensioned in accordance with the maximum dimensions of the folds treated.

Grâce à l'invention, les plis sont rangés sur chant. Ainsi est réalisé un gain de place important, deux sorties en case pouvant être disposées par exemple à la place d'une seule sortie en bac. De plus, seule la longueur maximale des plis traités est à prendre en compte pour dimensionner le réceptacle recevant les plis triés.Thanks to the invention, the folds are stored on edge. Thus, a significant space saving is achieved, two outputs in a box being able to be arranged for example in place of a single output in a container. In addition, only the maximum length of the treated folds is to be taken into account to size the receptacle receiving the sorted folds.

Le dispositif de déversement doit donc recevoir le pli vertical et le guider afin qu'il arrive sur son chant dans le réceptacle, où les plis doivent être rangés de façon satisfaisante. Ce guidage doit être réalisé parfaitement quelle que soit la rigidité du pli, qui peut être un courrier simple relativement flexible ou un prospectus relativement rigide et quel que soit le matériau constituant l'enveloppe du pli qui peut être de nature variée, en particulier du papier ou une pellicule de matière plastique.The spill device must therefore receive the vertical fold and guide it so that it reaches its edge in the receptacle, where the folds must be stored satisfactorily. This guiding must be carried out perfectly whatever the stiffness of the fold, which can be a relatively flexible simple mail or a relatively rigid flyer and whatever the material constituting the envelope of the fold which can be of varied nature, in particular paper or a plastic film.

La présente invention résoud ces problèmes et pour ce faire, le dispositif comprend :

  • une surface principale de guidage plane inclinée par rapport au plan vertical selon lequel descend par gravité l'objet plat en sortie de godet,
  • une palette de déviation et de maintien en aval de la surface principale,
  • un réceptacle incliné par rapport au plan horizontal, la palette étant mobile d'une position initiale où son bord inférieur est parallèle à et proche de la base de la paroi la plus basse du réceptacle, à une position finale où elle est proche de la paroi la plus haute du réceptacle.
The present invention solves these problems and to do this, the device comprises:
  • a main flat guide surface inclined relative to the vertical plane along which the flat object descends by gravity at the outlet of the bucket,
  • a range of deflection and maintenance downstream of the surface main,
  • a receptacle inclined relative to the horizontal plane, the pallet being movable from an initial position where its lower edge is parallel to and close to the base of the lowest wall of the receptacle, to a final position where it is close to the wall the highest of the receptacle.

Ainsi sont obtenues les qualités requises de déviation et de rangement sur chant dans le réceptacle. La surface principale de guidage dévie le pli de sa position initiale verticale à une position inclinée et la palette assure le freinage et la stabilisation de ce pli dans un premier temps. Dans un second temps, elle le dévie parallèlement aux parois du réceptacle et le pli vient se positionné parallèlement aux parois sur les plis éventuellement déjà rangés et elle le maintient dans cette position. Elle est articulée pour permettre son déplacement au cours de la formation de l'empilement vertical des plis.Thus are obtained the required qualities of deflection and storage on edge in the receptacle. The main guide surface deflects the fold from its initial vertical position to an inclined position and the pallet brakes and stabilizes this fold at first. In a second step, it deflects it parallel to the walls of the receptacle and the fold is positioned parallel to the walls on the folds which may already be stored and it maintains it in this position. It is articulated to allow its movement during the formation of the vertical stack of folds.

De préférence, en position initiale la palette est légèrement inclinée par rapport au plan vertical selon lequel descend l'objet plat en sortie de godet.Preferably, in the initial position, the pallet is slightly inclined relative to the vertical plane along which the flat object descends at the outlet of the bucket.

Afin d'améliorer le guidage du pli, le dispositif peut comprendre une surface secondaire sensiblement parallèle à la surface principale et formant avec elle une fente de passage pour l'objet plat et la surface principale peut être constituée simplement d'une surface statique de glissement à faible coefficient de frottement ou la surface principaleainsi que la surface secondaire peuvent être équipées d'une bande convoyeuse.In order to improve the guidance of the fold, the device can comprise a secondary surface substantially parallel to the main surface and forming with it a passage slot for the flat object and the main surface can simply consist of a static sliding surface. with a low coefficient of friction or the main surface as well as the secondary surface can be equipped with a conveyor belt.

Dans le cas où le réceptacle est une case, c'est-à-dire est fixe par rapport à la machine, la palette est articulée en son bord supérieur autour d'un axe horizontal de pivotement. Cet agencement est avantageux dans le cas où le nombre de plis triés pour cette destination est relativement limité. En effet le fait que la case ne soit pas remplie, ne gêne nullement au retrait des plis hors de la case. Ce genre de réceptacle permet également un gain de place, on peut de façon générale mettre au moins deux cases à la place d'un seul bac amovible.In the case where the receptacle is a box, that is to say is fixed relative to the machine, the pallet is articulated at its upper edge around a horizontal pivot axis. This arrangement is advantageous in the case where the number of folds sorted for this destination is relatively limited. Indeed the fact that the box is not filled, does not interfere with the withdrawal of the folds out of the box. This kind of receptacle also saves space, we can generally put at least two boxes in place of a single removable tray.

Dans le cas de bacs, c'est-à-dire de réceptacles plus grands amovibles, dans lesquels les plis triés peuvent être transportés pour leur traitement ultérieur, le déplacement de la palette seulement ne suffit pas. Dans ce cas, la surface principale et la palette sont fixées en un ensemble articulé autour d'un axe horizontal de pivotement.In the case of trays, that is to say larger removable receptacles, in which the sorted plies can be transported for their further processing, moving the pallet only is not enough. In this case, the main surface and the pallet are fixed in an assembly articulated around a horizontal pivot axis.

De préférence, cet ensemble est pivoté pas à pas grâce à un moteur.Preferably, this assembly is pivoted step by step thanks to a motor.

Lorsque la surface principale de guidage est équipée d'une bande convoyeuse, de préférence, l'axe horizontal de pivotement de l'ensemble est l'axe supérieur d'entraînement de la bande convoyeuse de la surface principale.When the main guide surface is equipped with a conveyor belt, preferably, the horizontal pivot axis of the assembly is the upper drive axis of the conveyor belt of the main surface.

Afin de permettre l'enlèvement du bac rempli, selon un agencement particulier, la palette est rétractable vers le haut.In order to allow removal of the filled container, according to a particular arrangement, the pallet is retractable upwards.

Selon une caractéristique particulière, la palette présente un bord inférieur conformé pour assurer un croisement avec le fond du réceptacle coopérant.According to a particular characteristic, the pallet has a lower edge shaped to ensure crossing with the bottom of the cooperating receptacle.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant un mode de réalisation.The invention is set out below in more detail with the aid of drawings representing an embodiment.

La figure 1 est une vue de face de deux variantes de réalisation du dispositif conforme à l'invention et équipant une machine de tri.Figure 1 is a front view of two alternative embodiments of the device according to the invention and fitted to a sorting machine.

La figure 2 est une vue de face de dispositifs conformes à l'invention, l'un étant en position initiale de rangement et l'autre en position finale.Figure 2 is a front view of devices according to the invention, one being in the initial storage position and the other in the final position.

Sur la figure 1, sont représentés deux dispositifs dont l'un correspond à une première variante A où le réceptacle est un bac 1 amovible et l'autre à une seconde variante B où le réceptacle est une case 2 fixe. Les éléments communs à ces deux variantes sont référencés de façon identique.In Figure 1, two devices are shown, one of which corresponds to a first variant A where the receptacle is a removable tray 1 and the other to a second variant B where the receptacle is a fixed box 2. The elements common to these two variants are referenced identically.

Les plis 3 sont acheminés dans des godets 4 se déplaçant selon un carrousel sur des rails. A l'ouverture du fond escamotable du godet 4, le pli tombe verticalement par gravité selon le plan P-P.The folds 3 are conveyed in buckets 4 moving in a carousel on rails. At the opening of the retractable bottom of the bucket 4, the fold falls vertically by gravity along the plane P-P.

La première variante A va tout d'abord être décrite.The first variant A will first be described.

Elle comprend une surface principale de guidage 5 plane inclinée d'un angle α égal sensiblement à 30° par rapport au plan P-P. Cette surface 5 est équipée d'une bande convoyeuse entraînée par des rouleaux 11, 12, le rouleau supérieur 11 étant actionné en rotation par un moteur 13 par l'intermédiaire d'une courroie sans fin 14.It comprises a main guide surface 5 inclined at an angle α equal to substantially 30 ° relative to the plane P-P. This surface 5 is equipped with a conveyor belt driven by rollers 11, 12, the upper roller 11 being actuated in rotation by a motor 13 by means of an endless belt 14.

Une surface secondaire 6 est disposée parallèlement à la surface principale 5 et est équipée également d'une bande convoyeuse entraînée par des rouleaux 15, 16 et actionnée en rotation par le même moteur 13 grâce à un agencement de courroies et de poulies de renvoi. Ainsi le pli est pincé entre ces deux surfaces 5, 6.A secondary surface 6 is arranged parallel to the surface main 5 and is also equipped with a conveyor belt driven by rollers 15, 16 and actuated in rotation by the same motor 13 thanks to an arrangement of belts and return pulleys. Thus the fold is pinched between these two surfaces 5, 6.

En aval du chemin de guidage ainsi réalisé est disposée une palette 7 de déviation et de maintien. Cette palette 7 est légèrement inclinée par exemple de 5° par rapport au plan P-P. Cette palette 7 est escamotable par translation vers le haut grâce à un agencement classique de poulies et de courroies crantées motorisées.Downstream of the guide path thus produced is arranged a pallet 7 for deflection and holding. This pallet 7 is slightly inclined for example by 5 ° relative to the plane P-P. This pallet 7 is retractable by translation upwards thanks to a conventional arrangement of pulleys and toothed motorized belts.

Le bac 1 est disposé sur un socle incliné d'un angle δ égal par exemple à 30° par rapport au plan horisontal. Les plis y sont rangés sur chant parallèlement à la paroi 1' du bac 1.The tank 1 is arranged on a base inclined at an angle δ equal for example to 30 ° relative to the horizontal plane. The folds are stored there on edge parallel to the wall 1 'of the tray 1.

L'ensemble surfaces principales 5 et secondaires 6, palette 7 et agencements d'entraînement associés est fixé sur une structure rigide essentiellement constituée de parois avant et arrière et est mobile par pivotement autour d'un axe d'articulation horizontal 9 qui est de préférence l'axe du rouleau supérieur 11 de la bande convoyeuse de la surface principale 5. Ce pivotement est réalisé pas à pas grâce à un moteur 10 par l'intermédiaire d'un agencement connu par exemple à vis et écrou.The set of main 5 and secondary 6 surfaces, pallet 7 and associated drive arrangements is fixed to a rigid structure essentially consisting of front and rear walls and is movable by pivoting around a horizontal articulation axis 9 which is preferably the axis of the upper roller 11 of the conveyor belt of the main surface 5. This pivoting is carried out step by step thanks to a motor 10 by means of a known arrangement, for example with screw and nut.

Ainsi l'ensemble est déplacé en fonction de la progression de la pile de plis dans le bac 1. Les positions extrêmes sont détectées par des capteurs mécaniques fin de course 17 et 18 (figure 2) permettant l'arrêt du dispositif lorsque le bac est plein et interdisant le déchargement des plis. Ils sont fixés sur le bâti de la machine de tri et coopèrent avec une pièce fixée sur le dispositif A.Thus, the assembly is moved as a function of the progression of the stack of plies in the bin 1. The extreme positions are detected by mechanical limit switches 17 and 18 (FIG. 2) allowing the device to stop when the bin is full and preventing the unloading of folds. They are fixed on the frame of the sorting machine and cooperate with a part fixed on the device A.

Un capteur 19 (figure 2) est disposé sur la face gauche de la palette 7 pour détecter l'absence d'espace libre entre la palette 7 et la pile de plis et commander le déplacement pas à pas de l'ensemble afin de recréer à nouveau un espace libre permettant l'arrivée des plis suivants.A sensor 19 (FIG. 2) is arranged on the left side of the pallet 7 to detect the absence of free space between the pallet 7 and the stack of plies and to control the stepwise movement of the assembly in order to recreate at new free space allowing the arrival of the following folds.

Le mode de fonctionnement est décrit précisément plus loin.The operating mode is described precisely below.

La seconde variante B de constitution plus simple est destinée au rangement sur chant dans une case 2 fixe de dimension moindre.The second variant B of simpler construction is intended for storage on edge in a fixed box 2 of smaller size.

La surface principale de guidage 5, inclinée d'un angle β d'environ 40° par rapport au plan P-P, est équipée d'une bande convoyeuse entraînée sur des rouleaux 11, 12 et actionnée en rotation par le moteur 13 par l'intermédiaire d'une courroie 14'. Cette dernière actionne également une bande convoyeuse équipant la surface secondaire 5 qui est dans ce cas limitée à la ligne de contact de la seconde bande avec la première où est pincé et entraîné le pli.The main guide surface 5, inclined at an angle β about 40 ° relative to the PP plane, is equipped with a conveyor belt driven on rollers 11, 12 and actuated in rotation by the motor 13 by means of a belt 14 '. The latter also actuates a conveyor belt equipping the secondary surface 5 which is in this case limited to the line of contact of the second band with the first where the fold is pinched and driven.

Une palette 7 est disposée en aval de la surface principale 5 et est librement articulée à son bord supérieur autour d'un axe horizontal 8 fixe sur la structure porteuse également fixe des bandes convoyeuses.A pallet 7 is arranged downstream of the main surface 5 and is freely articulated at its upper edge around a horizontal axis 8 fixed on the supporting structure also fixed conveyor belts.

La case 2 est fixée à la machine de tri, inclinée d'un angle δ d'environ 30° par rapport au plan horizontal.Box 2 is fixed to the sorting machine, inclined at an angle δ of about 30 ° relative to the horizontal plane.

Le pli vertical libéré du godet 4 est donc entraîné le long de la surface principale 5 puis vient buter contre la palette 7 où il est dévié pour venir se ranger sur son chant dans la case sur les plis éventuels déjà empilés.The vertical fold released from the bucket 4 is therefore driven along the main surface 5 and then abuts against the pallet 7 where it is deflected to come and line up on its edge in the box on any folds already stacked.

La palette 7, qui peut être sollicitée par un ressort de rappel, se déplace lors de la formation de la pile verticale par poussée des plis rangés contre sa face 7''. Au cours de ce déplacement, la palette 7 arrive au contact d'un capteur qui détecte le remplissage de la case 2 et qui suspend l'arrivée des plis dans cette case jusqu'au vidage de celle-ci par un opérateur.The pallet 7, which can be urged by a return spring, moves during the formation of the vertical stack by pushing the folds stored against its face 7 ''. During this movement, the pallet 7 comes into contact with a sensor which detects the filling of box 2 and which suspends the arrival of the folds in this box until the latter is emptied by an operator.

La figure 2 est une vue schématique représentant les éléments essentiels de la première variante A du dispositif conforme à l'invention. Selon cette figure, le dispositif de gauche est en position initiale de remplissage, le bac étant vide et le dispositif de droite en position finale, où le bac est rempli.Figure 2 is a schematic view showing the essential elements of the first variant A of the device according to the invention. According to this figure, the device on the left is in the initial filling position, the container being empty and the device on the right in the final position, where the container is filled.

En position initiale, la palette 7 a son bord inférieur 7' parallèle à et proche de la base de la paroi 1' la plus basse du bac 1 et dans la position finale, la palette 7 est proche de la paroi 1'' la plus haute du bac 1 ou même en butée contre celle-ci.In the initial position, the pallet 7 has its lower edge 7 'parallel to and close to the base of the lowest wall 1' of the tank 1 and in the final position, the pallet 7 is close to the most wall 1 '' high of tray 1 or even in abutment against it.

Par ailleurs, le bord inférieur 7' de la palette peut présenter une forme de peigne qui assure son croisement avec le fond du bac 1 ou de la case 2. Dans le cas de la case 2 (figure 3), le fond de celle-ci présente des fentes dans lesquelles passent les dents du peigne. Le même agencement peut être utilisé dans le cas du bac 1, mais de préférence, son fond présente des nervures entre lesquelles les dents du peigne passent et ainsi le bac 1 garde un fond fermé.Furthermore, the lower edge 7 ′ of the pallet can have a comb shape which ensures its crossing with the bottom of the tank 1 or of box 2. In the case of box 2 (FIG. 3), the bottom of this these have slots through which the teeth of the comb pass. The same arrangement can be used in the case of tray 1, but preferably, its bottom has ribs between which the teeth of the comb pass and thus the tray 1 keeps a closed bottom.

Il est possible de réaliser le dispositif sans surface secondaire la surface principale 5 assurant seule le guidage du pli 3 vers la palette 7 où il est freiné, stabilisé et dévié.It is possible to produce the device without a secondary surface, the main surface 5 ensuring only the guiding of the fold 3 towards the pallet 7 where it is braked, stabilized and deflected.

Il est aussi possible de réaliser le dispositif, dans sa variante A ou B, avec une surface principale 5 statique et à faible coefficient de frottement.It is also possible to make the device, in its variant A or B, with a main static surface 5 and with a low coefficient of friction.
