Les machines de fabrication d'enveloppes travaillent en continu et avec une cadence de production importante. Il est nécessaire, lors du conditionnement, de regrouper les enveloppes produites en lots, c'est d'ailleurs l'objet de la demande de brevet français FR-A-2600992 au nom de la demanderesse. Ces enveloppes, une fois regroupées par lots, sont alors conditionnées, cette opération est le plus généralement réalisée de façon manuelle.The envelope making machines work continuously and with a high production rate. It is necessary, during packaging, to group the envelopes produced in batches, this is also the subject of French patent application FR-A-2600992 in the name of the applicant. These envelopes, once grouped in batches, are then packaged, this operation is generally carried out manually.

On connaît toutefois la demande de brevet français FR-A-2 318 788 qui décrit un dispositif pour former des paquets avec des piles de sachets en papier comprenant un moyen de saisie et de basculement des piles et un moyen d'évacuation des piles vers un poste de réception pour la formation des paquets, ledit moyen d'évacuation ou de transport étant constitué d'un chariot coulissant sur des guidages.However, French patent application FR-A-2 318 788 is known, which describes a device for forming packages with stacks of paper bags comprising a means for gripping and tilting the stacks and a means for discharging the stacks towards a receiving station for the formation of packages, said means of evacuation or transport consisting of a carriage sliding on guides.

Dans le but d'améliorer la fiabilité ainsi que les conditions de travail, tout en s'adaptant à des cadences de fabrication de plus en plus élevées, l'invention propose un nouveau dispositif automatique de sélection et de conditionnement.In order to improve reliability as well as working conditions, while adapting to increasingly high production rates, the invention proposes a new automatic selection and packaging device.

Selon l'invention, ce nouveau dispositif est du type comme décrit par ledit document FR-A-2318788, qui est en outre caractérisé en ce que que le moyen de saisie du lot est constitué d'une première pince susceptible de déplacer les lots à partir du moyen de sélection jusqu'au moyen de basculement, et d'une deuxième pince susceptible d'un mouvement entraînant les enveloppes entre des positions verticale et horizontale et en ce que ledit dispositif comprend un moyen distributeur du lot d'enveloppes destiné à placer les lots à partir du moyen de basculement dans des emballages, ledit moyen distributeur comportant une troisième pince à mouvement de translation.According to the invention, this new device is of the type as described by said document FR-A-2318788, which is further characterized in that the means for gripping the lot consists of a first clamp capable of moving the lots to from the selection means to the tilting means, and from a second clamp capable of movement causing the envelopes between vertical and horizontal positions and in that said device comprises means for distributing the batch of envelopes intended to place the batches from the tilting means in packages, said distributor means comprising a third clamp with translational movement.

Le moyen distributeur comporte deux volets latéraux et une pince à déplacement longitudinal parallèle aux deux volets.The dispensing means comprises two lateral flaps and a clamp with longitudinal displacement parallel to the two flaps.

Ce dispositif distributeur est complété par un plateau rotatif muni de cornières de centrage ou d'une piste à rampes de galets inclinées autocentreuse supportant l'emballage.This dispensing device is completed by a rotary plate provided with centering angles or a track with self-centering inclined roller ramps supporting the packaging.

Le moyen d'évacuation est plus particulièrement un poussoir animé d'un mouvement de translation permettant le glissement du carton perpendiculairement au côté libre de cornière.The evacuation means is more particularly a pusher with a translational movement allowing the cardboard to slide perpendicular to the free side of the angle iron.

D'autres détails, objets et avantages de la présente invention seront plus apparents au fur et à mesure de la description d'un mode de réalisation particulier tel qu'il va suivre.Other details, objects and advantages of the present invention will become more apparent as the description of a particular embodiment as it follows follows.

La figure unique présente le dispositif selon l'invention dans une forme éclatée.The single figure shows the device according to the invention in an exploded form.

Le dispositif de sélection d'enveloppes par lots 1 est monté rotatif sur un axe 10 qui le rend effaçable sur incident du dispositif selon l'invention. Une plaque de réception 11 permet de maintenir les enveloppes dans une position verticale tandis que le doigt de sélection 12 actionné par un vérin 13 définit des lots d'enveloppes lorsqu'il est commandé par un dispositif opto-électronique non représenté, tel que celui de la demande de brevet no 2600 992. Le lot d'enveloppes est alors saisi latéralement par une pince 20 constituée d'une cornière 21 tandis qu'une barrette 22 assure le serrage sous l'effet des vérins 23 et 24. Cet ensemble cornière plus vérin est également déplaçable en translation sous l'effet d'un vérin 25 et des deux barres de guidage 26 et 27. Le vérin 25 et les deux barres 26 et 27 sont parallèles.The device for selecting envelopes in batches 1 is rotatably mounted on an axis 10 which makes it erasable on incident from the device according to the invention. A receiving plate 11 keeps the envelopes in a vertical position while the selection finger 12 actuated by a jack 13 defines batches of envelopes when it is controlled by an opto-electronic device not shown, such as that of patent application No. 2 600 992. the batch of envelopes is then gripped laterally by a clamp 20 consisting of a bracket 21 while a bar 22 ensures clamping under the effect of jacks 23 and 24. This bracket assembly more cylinder is also movable in translation under the effect of a cylinder 25 and two guide bars 26 and 27. Cylinder 25 and two bars 26 and 27 are parallel.

Lorsque le moyen de saisie est reculé dans sa position maximum le moyen de basculement 3 se trouve entre le moyen de saisie et le moyen de sélection effaçable. Ce moyen de basculement est constitué d'une pince particulière comportant une plaque 30 dont la longueur est supérieure à la longueur de la cornière 21 de façon que sa partie inférieure soit au même niveau que la partie inférieure de la cornière 21 c'est-à-dire au niveau du plan de la table tandis que sa partie supérieure se trouve au-dessus du dispositif de saisie. Le dispositif de saisie en lui-même est constitué d'une barrette 31 actionnée par des vérins tels que 32 et dont la plus grande longueur est disposée perpendiculairement à l'axe longitudinal de la cornière 21 ou de la plaque 30. Parallèlement, cette même barrette 31 assure sous l'effet des vérins un effort de serrage sur la partie haute de la plaque 30. La plaque 30 et la barrette 31 associée aux vérins 32 sont disposées de part et d'autre d'une pièce de supportage 33 pouvant pivoter autour d'un axe 34. A cet effet, la structure 35 qui supporte les vérins et la plaquette 31 se prolonge en partie au-dessus de la pièce 33 de façon à pouvoir jouer un rôle de levier soumis à l'action d'un vérin 36. L'axe 34 est orienté dans une direction parallèle au mouvement de translation du moyen de saisie 2. Le vérin 36 par contre a son axe disposé perpendiculairement à l'axe de pivotement 34.When the gripping means is moved back to its maximum position, the tilting means 3 is located between the gripping means and the erasable selection means. This tilting means consists of a particular clamp comprising a plate 30 whose length is greater than the length of the angle 21 so that its lower part is at the same level as the lower part of the angle 21 that is - say at the level of the table plan while its upper part is above the input device. The gripping device itself consists of a bar 31 actuated by jacks such as 32 and the greatest length of which is disposed perpendicular to the longitudinal axis of the angle iron 21 or of the plate 30. At the same time, this same bar 31 ensures under the effect of the jacks a clamping force on the upper part of the plate 30. The plate 30 and the bar 31 associated with the jacks 32 are arranged on either side of a support piece 33 which can pivot around an axis 34. To this end, the structure 35 which supports the jacks and the plate 31 extends partly above the part 33 so as to be able to act as a lever subjected to the action of a actuator 36. The axis 34 is oriented in a direction parallel to the translational movement of the gripping means 2. The actuator 36, on the other hand, has its axis arranged perpendicular to the pivot axis 34.

Le moyen distributeur 4 est constitué d'une structure de supportage 40 dans laquelle sont disposés des axes 41, 42, et 43 sur lesquels peut coulisser un chariot 44 entraîné par un système vis 45 écrou 46 motorisé 47. Ce dispositif peut être remplacé par un vérin sans tige comportant un piston libre magnétique qui circule à l'intérieur du corps et une pièce d'entrainement coulissante. Une nouvelle pince 48 est solidaire du chariot 44. Elle est constituée d'une plaque fixe 49 disposée dans un plan horizontal et une plaque mobile 50 autour d'un axe 51 sous l'effet du vérin 52.The dispensing means 4 consists of a support structure 40 in which axes 41, 42 and 43 are arranged on which a carriage 44 can slide, driven by a screw 45 nut 46 motorized 47 system 47. This device can be replaced by a rodless cylinder comprising a free magnetic piston which circulates inside the body and a sliding drive part. A new clamp 48 is integral with the carriage 44. It consists of a fixed plate 49 arranged in a horizontal plane and a movable plate 50 around an axis 51 under the effect of the jack 52.

Le distributeur proprement dit est constitué de deux volets 53 et 54 disposés en position fermée dans un plan horizontal parallèle à la plaque fixe 49 de la pince 48 mais à un niveau inférieur. Des cornières 55, 56 bloquées sur la structure de supportage 40 permettent un réglage en hauteur par les pièces coulissantes 55, 56 tandis que les barres latérales telles que 57 supportent les vérins 58 orientés perpendiculairement au mouvement de translation de la pince 48 et dont le montage sur étrier permet de faire pivoter les volets vers le bas de façon à ce que le plan de chacun des volets soit vertical.The distributor itself consists of two flaps 53 and 54 arranged in the closed position in a horizontal plane parallel to the fixed plate 49 of the clamp 48 but at a lower level. Angle brackets 55, 56 blocked on the support structure 40 allow height adjustment by the sliding parts 55, 56 while the lateral bars such as 57 support the jacks 58 oriented perpendicular to the translation movement of the clamp 48 and the mounting of which on stirrup allows you to rotate the flaps down so that the plane of each flap is vertical.

La plaque 60 du dispositif à plateau rotatif 6 est directement liée à la tige 61 d'un vérin 62 qui assure un mouvement monte et baisse selon la flèche 63 tandis que le vérin 62 est lui-même monté sur un dispositif rotatif non figuré lui permettant un déplacement angulaire par secteur. Dans l'exemple particulier représenté chacun des secteurs a une valeur de 90°. L'emballage 64 qui repose sur la plaque 60 est positionné grâce à des cornières 65 solidaires de cette même plaque 60 et disposées pour bloquer trois des faces dudit emballage. Ces cornières peuvent être remplacées par une piste à rampes de galets inclinées autocentreuse (non figuré).The plate 60 of the turntable device 6 is directly linked to the rod 61 of a jack 62 which ensures an upward and downward movement according to the arrow 63 while the jack 62 is itself mounted on a not shown rotary device allowing it angular displacement by sector. In the particular example shown, each of the sectors has a value of 90 °. The package 64 which rests on the plate 60 is positioned by means of angles 65 integral with the same plate 60 and arranged to block three of the faces of said package. These angles can be replaced by a track with self-centering inclined roller ramps (not shown).

Le moyen d'évacuation des emballages 7 est un poussoir 70 monté à l'extrémité de la tige 71 d'un vérin fixe 72. La longueur de travail de ce vérin est choisie en fonction de la plus grande longueur des emballages utilisés dans ce dispositif de conditionnement.The means for evacuating the packages 7 is a pusher 70 mounted at the end of the rod 71 of a fixed jack 72. The working length of this jack is chosen as a function of the greatest length of the packages used in this device conditioning.

Nous allons maintenant décrire le fonctionnement d'un dispositif de sélection et de manutention particulier tel qu'il vient d'être décrit. Les enveloppes issues de la machine de fabrication s'accumulent contre la plaque 11 du dispositif de sélection effaçable 1 et lorsque la quantité d'enveloppes est atteinte, le doigt de sélection 12 s'insère entre les enveloppes pour définir un lot. Celui-ci est alors saisi par la pince 20 entre l'une des ailes de la cornière 21 et la barrette 22 par mise en service des vérins 23 et 24. Le blocage du lot d'enveloppes dans la cornière étant maintenu, le vérin 25 est actionné en traction et fait effectuer à l'ensemble de la pince 20 et de son lot d'enveloppes un déplacement en translation jusqu'à ce que la tige du vérin 25 vienne en butée.We will now describe the operation of a particular selection and handling device as it has just been described. The envelopes from the manufacturing machine accumulate against the plate 11 of the erasable selection device 1 and when the quantity of envelopes is reached, the selection finger 12 is inserted between the envelopes to define a batch. This is then gripped by the clamp 20 between one of the wings of the angle iron 21 and the bar 22 by putting the jacks 23 and 24 into service. The blocking of the batch of envelopes in the angle iron being maintained, the jack 25 is actuated in traction and causes the assembly of the clamp 20 and its batch of envelopes to move in translation until the rod of the jack 25 comes into abutment.

Le lot d'enveloppes a alors sa partie médiane qui coïncide avec le dispositif de basculement 3. Sous l'effet des vérins tels que 32, la barrette de pressage 31 vient en appui en partie hau te des enveloppes pour les presser contre la plaque 30 et assurer ainsi un nouveau blocage. Les vérins 23 et 24 sont alors actionnés en sens inverse pour libérer le lot d'enveloppes de la pince 20. La pression étant maintenue dans les vérins 32, le vérin 36 est alors mis en action pour amener le lot d'enveloppes qui repose sur la plaque 30 dans un plan quasi-horizontal.The batch of envelopes then has its middle part which coincides with the tilting device 3. Under the effect of jacks such as 32, the pressing bar 31 comes to bear partly upwards of the envelopes to press them against the plate 30 and thus ensure a new blocking. The jacks 23 and 24 are then actuated in the opposite direction to release the batch of envelopes from the clamp 20. The pressure being maintained in the jacks 32, the jack 36 is then actuated to bring the batch of envelopes which rests on the plate 30 in a quasi-horizontal plane.

Le lot d'enveloppes est saisi à son extrémité libre par la pince 48. En effet, le vérin 52 mis en service actionne la plaque mobile 50 qui vient presser le lot d'enveloppes dans son épaisseur entre cette même plaque mobile 50 et la plaque fixe 49. La pression étant relâchée dans les vérins 32, le blocage par la plaquette 31 est supprimé. Le moteur 47 actionné fait tourner la vis 45 et assure le déplacement de l'écrou 46 et de façon simultanée celui du chariot 44 qui supporte la pince 52 qui elle-même maintient le lot d'enveloppes.The batch of envelopes is gripped at its free end by the clamp 48. In fact, the jack 52 put into service actuates the movable plate 50 which presses the batch of envelopes in its thickness between this same movable plate 50 and the plate fixed 49. The pressure being released in the jacks 32, the blocking by the plate 31 is eliminated. The actuated motor 47 turns the screw 45 and ensures the displacement of the nut 46 and simultaneously that of the carriage 44 which supports the clamp 52 which itself maintains the batch of envelopes.

Ce dernier est alors entraîné par glissement sur la plaque 30 et sur chacun des volets 53 et 54. Lorsque le chariot 44 est arrivé en fin de course, le moyen de basculement 3 est ramené à sa position initiale. La pince 52 est alors rendue inactive et le paquet d'enveloppes repose donc uniquement sur les deux volets puisque la plaque mobile inférieure 50 est revenue en position initiale.The latter is then driven by sliding on the plate 30 and on each of the flaps 53 and 54. When the carriage 44 has reached the end of the stroke, the tilting means 3 is returned to its initial position. The clamp 52 is then made inactive and the package of envelopes therefore rests only on the two flaps since the lower movable plate 50 has returned to the initial position.

Le plateau tournant 6 a parallèlement été alimenté par un emballage du type carton ,ces moyens d'alimentation n'étant pas représentés car réalisés de façon classique. Cet emballage 64 a sa plus grande longueur orientée parallèlement à la direction de translation de la pince 52 et par conséquent parallèlement à la plus grande longueur des enveloppes. La disposition des cornières 65 sont telles que le carton se trouve parfaitement aligné avec le lot d'enveloppes.The turntable 6 has at the same time been supplied with cardboard-type packaging, these supply means not being shown since they are produced in a conventional manner. This package 64 has its greatest oriented length parallel to the direction of translation of the clamp 52 and therefore parallel to the greatest length of the envelopes. The arrangement of the angles 65 are such that the cardboard is perfectly aligned with the batch of envelopes.

Le vérin 62 qui supporte la plaque 60 est alors mis en pression pour que le carton vienne immédiatement en-dessous du lot d'enveloppes. Les vérins tels que 58 mis en pression assurent le déplacement angulaire des volets et libèrent le lot d'enveloppes qui par gravité tombe dans l'emballage. Le plateau tournant est alors ramené en position basse et le système de mouvement angulaire fait effectuer à l'emballage un double mouvement de rotation de 90° de façon à ce que le lot suivant d'enveloppes soit disposé tête-bêche avec le premier lot. Ainsi, la symétrie du chargement est respectée compte tenu des surépaisseurs dues au rabat des enveloppes.The jack 62 which supports the plate 60 is then pressurized so that the carton comes immediately below the batch of envelopes. The cylinders such as 58 pressurized ensure the angular displacement of the flaps and release the batch of envelopes which by gravity falls into the packaging. The turntable is then returned to the low position and the angular movement system causes the packaging to perform a double rotation movement of 90 ° so that the next batch of envelopes is arranged head to tail with the first batch. Thus, the symmetry of the load is respected taking into account the extra thicknesses due to the flap of the envelopes.

On peut associer également à ce dispositif un pressoir non représenté dans l'exemple décrit qui a pour rôle de comprimer chacun des lots d'enveloppes après qu'il ait été introduit évacuant ainsi l'air contenu entre les différentes feuilles.One can also associate with this device a press not shown in the example described which has the role of compressing each of the batches of envelopes after it has been introduced thus evacuating the air contained between the different sheets.

Une fois l'emballage complété, le dernier mouvement de rotation est un mouvement de rotation simple de façon à ce que l'emballage effectue un quart de tour. Le sens de rotation est tel que le U formé par les trois cornières de positionnement ait sa base orientée vers le moyen d'évacuation 7. Ce dernier est alors actionné par mise en pression du vérin 72, qui prenant appui sur l'emballage par l'intermédiaire du poussoir 70 évacue ledit emballage hors de la plaque 60 vers un dispositif de transport adéquat non représenté.Once the packaging has been completed, the last rotational movement is a simple rotational movement so that the packaging performs a quarter turn. The direction of rotation is such that the U formed by the three positioning angles has its base oriented towards the discharge means 7. The latter is then actuated by pressurizing the jack 72, which is supported on the packaging by the 'Intermediate pusher 70 evacuates said packaging from the plate 60 to a suitable transport device not shown.
