Description
La présente invention concerne un dispositif de transfert d'objets plats. Elle vise également un dispositif de dépilage d'objets plats équipé de ce dispositif de transfert.The present invention relates to a device for transferring flat objects. It also relates to a device for unstacking flat objects equipped with this transfer device.
Un dispositif de dépilage d'objets plats comprend quatre organes principaux:
- un magasin d'approvisionnement du courrier,
- un préhenseur de courrier,
- un séparateur de prises doubles,
- un dispositif de transfert ou évacuateur.
- a mail supply store,
- a mail gripper,
- a double outlet separator,
- a transfer device or spillway.
Le courrier est posé sur chant sur un tapis, adossé à une palette. Grâce à une motorisation simultanée du tapis et de la palette, le courrier avance vers le préhenseur. Le tapis débouche sur un brusque changement de niveau, appelé dans la suite chute, à proximité du préhenseur de courrier. Le magasin d'approvisionnement, disposé entre cette chute et le préhenseur, est prévu pour recevoir les plis ou objets plats en attente de dépilage. Le préhenseur comprend des zones de dépression devant lesquelles passe une courroie perforée.The mail is placed on edge on a carpet, against a pallet. Thanks to a simultaneous motorization of the conveyor and the pallet, the mail advances towards the gripper. The carpet leads to an abrupt change in level, called in the following fall, near the mail gripper. The supply magazine, located between this chute and the gripper, is designed to receive folds or flat objects awaiting unstacking. The gripper includes vacuum zones in front of which a perforated belt passes.
Au sortir du préhenseur, le courrier passe devant la zone à dépression du séparateur de prises doubles, situé sur l'autre face du courrier. Cet organe retient les courriers qui seraient entraînés par friction par le courrier précédent, de façon à ne laisser partir qu'un seul courrier à la fois.When leaving the gripper, the mail passes in front of the vacuum zone of the double outlet separator, located on the other side of the mail. This body retains the mail which would be driven by friction by the previous mail, so as to let go only one mail at a time.
En sortie du séparateur de prises doubles, le courrier est pris en charge dans un dispositif de transfert qui assure l'interface entre le dispositif de dépilage et un dispositif de tri.At the output of the double outlet separator, the mail is taken up in a transfer device which provides the interface between the unstacking device and a sorting device.
Le tri des courriers grand format s'effectuant par insertion dans des godets, le dépilage doit se faire à la demande et non en continu.The sorting of large format mail is done by insertion into buckets, unstacking must be done on demand and not continuously.
Il est également nécessaire de stopper le courrier presque immédiatement après son entrée dans le dispositif de transfert. Or les moyens traditionnels donnent une grande dispersion sur l'arrêt du courrier à cause de rebonds importants lors du passage de courriers épais, conduisant alors à une perte de contact avec le pli alors qu'il est temps de l'arrêter.It is also necessary to stop mail almost immediately after entering the forwarding device. However, the traditional means give a great dispersion on the stopping of the mail because of significant rebounds during the passage of thick mail, then leading to a loss of contact with the fold when it is time to stop it.
On connaît déjà par la demande de brevet français n°9109431 du 25 Juillet 1991 au nom de la Demanderesse un dispositif de dépilage de plis de courrier comprenant à sa sortie des moyens de transfert des plis constitués de deux courroies associées pour agir par pincement. Mais ces moyens de transfert ne peuvent assurer le transfert d'objets d'épaisseur variable, et fonctionnent en permanence.Already known from French patent application No. 9109431 of July 25, 1991 in the name of the Applicant, a device for unstacking mail folds comprising at its outlet means for transferring folds consisting of two belts associated to act by pinching. However, these transfer means cannot transfer objects of variable thickness, and operate continuously.
Le but de l'invention est de proposer un dispositif de transfert apte à arrêter un objet plat d'épaisseur "quelconque" et notamment de grand format en sortie d'un dispositif de dépilage, à délivrer cet objet plat à la demande à un dispositif de tri et dont l'agencement contribue à minimiser la dispersion des temps d'arrêt des objets plats à l'intérieur de celui-ci.The object of the invention is to provide a transfer device capable of stopping a flat object of "any" thickness and in particular large format at the output of a unstacking device, to deliver this flat object on demand to a device sorting and whose arrangement contributes to minimizing the dispersion of downtime of flat objects inside it.
Selon l'invention, il est proposé un dispositif de transfert d'objets plats, pour transférer vers des moyens de tri des objets plats en sortie d'un dispositif de dépilage d'objets plats, caractérisé en ce qu'il comprend des moyens pour pincer un objet plat initialement situé dans un plan de transfert, ces moyens étant agencés pour se déplacer dans une direction sensiblement perpendiculaire au premier plan et en ce que ces moyens de pincement sont commandés pour immobiliser ledit objet plat dans l'attente d'une autorisation de transfert vers les moyens de tri.According to the invention, there is proposed a device for transferring flat objects, for transferring to sorting means flat objects at the outlet of a device for unstacking flat objects, characterized in that it comprises means for pinch a flat object initially located in a transfer plane, these means being arranged to move in a direction substantially perpendicular to the foreground and in that these pinch means are controlled to immobilize said flat object while awaiting authorization transfer to sorting means.
Ainsi, il devient possible d'arrêter des objets d'épaisseur variable et de réaliser leur transfert vers un dispositif de tri conçu pour traiter chaque objet l'un après l'autre.Thus, it becomes possible to stop objects of variable thickness and carry out their transfer to a sorting device designed to process each object one after the other.
Dans un mode de réalisation préféré de l'invention, les moyens pinceurs comprennent deux rouleaux pinceurs comportant sur leur périphérie un matériau mou et dont au moins l'un des deux est mobile dans un second plan de déplacement perpendiculaire audit premier plan et, pour chaque rouleau, un ensemble de courroies d'entraînement tendues autour dudit rouleau et d'au moins une poulie de renvoi disposée de part et d'autre dudit rouleau.In a preferred embodiment of the invention, the pinching means comprise two pinching rollers comprising on their periphery a soft material and at least one of which is movable in a second plane of movement perpendicular to said first plane and, for each roller, a set of drive belts stretched around said roller and at least one return pulley disposed on either side of said roller.
Suivant un autre aspect de l'invention, le dispositif de dépilage d'objets plats comprenant des moyens d'approvisionnement en objets plats, des moyens préhenseurs, des moyens séparateurs de prises doubles, et un dispositif de transfert d'objets plats selon l'invention, est caractérisé en ce que le dispositif de transfert d'objets plats comprend des moyens pour pincer un objet plat préalablement entraîné par des moyens préhenseurs, ces moyens pinceurs étant commandés de sorte que ledit objet plat est transféré par ledit dispositif de transfert après réception d'une autorisation de transfert.According to another aspect of the invention, the device for unstacking flat objects comprising means for supplying flat objects, gripping means, means for separating double sockets, and a device for transferring flat objects according to the invention is characterized in that the device for transferring flat objects comprises means for gripping a flat object previously driven by gripping means, these gripping means being controlled so that said flat object is transferred by said transfer device after reception a transfer authorization.

On va maintenant décrire un dispositif de dépilage d'objets plats équipé d'un dispositif de transfert selon l'invention, en même temps que le fonctionnement de ce dispositif de transfert, en référence aux figures 1 à 3.We will now describe a device for unstacking flat objects equipped with a transfer device. according to the invention, at the same time as the operation of this transfer device, with reference to FIGS. 1 to 3.
Le dispositif de dépilage 10 comprend un tapis mobile 14 sur lequel le courrier est posé à chant, un magasin d'approvisionnement 13, un préhenseur d'objets plats 16, un séparateur de prises doubles 11 et un dispositif de transfert d'objets plats 20 selon l'invention. Le préhenseur 16 comprend une courroie perforée 15 se déplaçant devant une zone de dépression 12.The
Lorsque les objets plats posés sur le tapis 14 atteignent le bord de ce tapis, ils sont entraînés dans la magasin d'approvisionnement 13. Le premier objet plat est attiré par le préhenseur 16 du fait de la dépression générée au niveau de la zone de dépression à travers les perforations de la courroie 15. Celle-ci entraîne alors cet objet plat dans une direction perpendiculaire à la direction de déplacement du tapis 14, vers le séparateur de prises doubles 11. Ce séparateur comprend une zone de dépression et a pour fonction de retenir un objet plat qui aurait été éventuellement entraîné par friction par un objet plat précédent. L'objet plat 1, posé sur chant sur un plan sensiblement horizontal 31, est ensuite entraîné dans un plan de transfert P sensiblement vertical entre deux rouleaux pinceurs 21, 22 montés en vis à vis par rapport au plan P. Chaque rouleau pinceur 21, 22 est disposé entre deux poulies 23 et 24, respectivement 25 et 35. Ces poulies 23, 24, respectivement 25, 35 sont montées selon un alignement parallèle au plan P de telle façon que les poulies 23 et 25, respectivement 24 et 35 se font face par rapport au plan P et définissent un passage pour un pli s'étendant dans le plan P. Deux courroies 27, 30 engagent le rouleau 21 et les poulies 23 et 24 sur deux niveaux et deux courroies 28, 29 engagent le rouleau 22 et les poulies 24 et 35 sur deux niveaux en faisant face respectivement aux courroies 27 et 30 par rapport au plan P.When the flat objects placed on the
Les rouleaux pinceurs 21, 22 comportent de préférence sur leur périphérie une couronne en matériau mou 21a, 22a qui permet de supprimer tout risque de rebond du courrier et contribue à l'obtention d'un arrêt quasi-immédiat d'un pli pincé entre les deux rouleaux. Ces rouleaux pinceurs ont un diamètre suffisamment important pour favoriser la pénétration des plis épais entre eux. Le diamètre des rouleaux 21 et 22 est plus grand que celui des poulies 23, 24, 25, 35 de sorte que les courroies 28, 29 viennent seulement en contact avec les courroies 27, 30 respectivement en un point de pincement situé entre les axes des deux rouleaux et indiqué par le point d'intersection entre le plan P et le plan D sur la figure 2.The
La motorisation du dispositif de transfert 20 peut être assurée soit au niveau des rouleaux pinceurs 21, 22, soit au niveau des poulies 23, 24, 25, 35. Dans un mode préféré de réalisation, les deux rouleaux pinceurs 21, 22 peuvent se déplacer librement dans un plan de déplacement D perpendiculaire au plan de transfert des plis. Dans un second mode de réalisation, seul un des rouleaux pinceurs est mobile, l'autre restant fixe. Le ou les rouleaux mobile(s) dans le plan D s'efface(nt) devant un pli qui pénètre dans le passage entre les poulies 24 et 35 et les courroies 27 à 30 maintenues tendues, agissent pour rapprocher les deux rouleaux 21, 22 l'un contre l'autre de telle façon à pincer le pli. Le dispositif de transfert 20 est de préférence placé le plus près possible du préhenseur 16 et possède un plan de transfert P qui est de préférence parallèle au plan de préhension. Par ailleurs, le séparateur de prises doubles 11 est de préférence placé entre les deux niveaux de courroie 28, 29 et en amont des rouleaux pinceurs 21, 22, en référence à la figure 3.The motorization of the
La mise en oeuvre de deux niveaux de courroies de part et d'autre du séparateur de prises doubles 11 présente l'intérêt de contribuer à la création d'une résultante de forces de contact qui est située au voisinage immédiat du séparateur 11. Un seul niveau de courroies aurait pour effet d'entraîner la création d'un mouvement qui provoquerait des plis, et par conséquent un changement d'inclinaison des plis.The use of two levels of belts on either side of the
Les rouleaux pinceurs 21, 22 ont pour fonction d'immobiliser chaque objet plat en attendant une autorisation de transfert vers des godets de tri (non représentés). Cette autorisation de transfert peut être émise par des moyens de contrôle et de traitement associés aux moyens de tri. Pour conserver un débit acceptable, les rouleaux pinceurs sont placés immédiatement après le séparateur de prises doubles 11.The
Un dispositif de transfert selon l'invention permet donc d'assurer un arrêt quasi-immédiat de chaque pli pris en compte quelle que soit son épaisseur et sa forme et contribue donc à réduire considérablement la dispersion observée généralement dans l'arrêt des plis.A transfer device according to the invention therefore makes it possible to ensure an almost immediate stop of each fold taken into account whatever its thickness and its shape and therefore contributes to considerably reducing the dispersion generally observed in the stop of the folds.
Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et de nombreux aménagements peuvent être apportés à ces exemples sans sortir du cadre de l'invention. Ainsi, on peut prévoir de nombreux types de motorisation des rouleaux pinceurs ainsi que des procédures de contrôle du fonctionnement du dispositif de transfert prenant en compte les spécificités du dispositif de tri situé en aval du dispositif de dépilage. On peut également envisager un nombre de courroies différent de deux et un autre agencement des poulies associées aux courroies.Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention. Thus, many types of motorization of the pinch rollers can be provided as well as procedures for controlling the operation of the transfer device taking into account the specificities of the sorting device located downstream of the unstacking device. One can also consider a number of belts other than two and another arrangement of the pulleys associated with the belts.
