Description
La présente invention concerne un dispositif de dépilage d'objets plats en particulier de plis de courrier notamment ouverts du type brochures publicitaires ou autres, comportant un moyen pour porter une pile de plis sur chant en butée contre une rive de taquage, un moyen pour dépiler séquentiellement lesdits plis, ce moyen de dépilage étant disposé devant la face libre du premier pli de la pile et effectuant une translation dudit pli à une vitesse V₁ perpendiculaire à la pile sous contrôle de moyens de détection de la position du pli, un moyen de transfert pour transférer le pli dépilé à une vitesse V₂, un organe anti prise double intercalé entre ces deux moyens de dépilage et de transfert, cet organe anti prise double étant une tête à dépression agissant sur l'autre face du pli pour le retenir et ayant une force de rétention qui est inférieure à la force de translation du moyen de transfert, la vitesse V1 de l'organe de translation étant inférieure à la vitesse V2 du moyen de transfert.The present invention relates to a device for unstacking flat objects, in particular mail folds, in particular open, of the advertising brochure or other type, comprising means for carrying a stack of folds on edge in abutment against a jogging edge, means for unstacking sequentially said folds, this unstacking means being disposed in front of the free face of the first fold of the stack and carrying out a translation of said fold at a speed V₁ perpendicular to the stack under control of means for detecting the position of the fold, a transfer means to transfer the depilated fold at a speed V₂, a double anti-gripping member interposed between these two destacking and transfer means, this double anti-gripping member being a vacuum head acting on the other face of the fold to retain it and having a retention force which is less than the translation force of the transfer means, the speed V1 of the translation member being less than l at speed V2 of the transfer means.
Un tel dispositif est connu du document US-3 847 383.Such a device is known from document US-3,847,383.
Les documents US-4 893 804 et US-435 7007 divulguent un dispositif de dépilage analogue dans lequel l'organe antiprise double est constitué d'un rouleau agissant contre le déplacement des plis en sortie du moyen de dépilage ou encore d'un volet articulé.Documents US Pat. .
Dans le dispositif de dépilage connu du US-3 8 47 383, l'organe antiprise double est constamment en dépression ce qui pose des problèmes d'éfficacité pour certains types de plis.In the unstacking device known from US Pat. No. 3,847,383, the double anti-grip member is constantly under vacuum, which poses efficiency problems for certain types of folds.
C'est principalement le cas lorsque les plis traités sont des objets ouverts, de type brochures publicitaires ou autres. Ces brochures peuvent se composer par exemple d'une feuille pliée en plusieurs volets ou de quelques feuillets reliés tel un petit fascicule. Le fonctionnement continu de l'organe antiprise double est néfaste car il provoque des bourrages ou des déchirements des plis dépilés.This is mainly the case when the folds processed are open objects, such as advertising brochures or others. These brochures can consist, for example, of a sheet folded in several sections or of a few sheets linked like a small booklet. The continuous operation of the double anti-socket device is harmful because it causes jams or tears in the depilated folds.
Le but de l'invention est de résoudre ces problèmes de dépilage et de prises doubles sur des plis ouverts.The object of the invention is to solve these problems of unstacking and double sockets on open pleats.
Ce problème est résolu par le dispositif de dépilage selon la revendication 1.This problem is solved by the unstacking device according to
Dans la pratique, on constate que le nombre de prises doubles où les fronts avant des deux plis coïncident est très faible.In practice, it is found that the number of double takes where the front edges of the two folds coincide is very low.
Ces cas surviennent avec une fréquence inférieure à la fréquence de prises doubles couramment tolérée. En général, une prise double présente un décalage entre les fronts avant des deux plis concernés.These cases occur with a frequency lower than the frequency of double taps currently tolerated. In general, a double grip has an offset between the front edges of the two folds concerned.
Le dispositif grâce à trois détecteurs permet de commander l'organe antiprise double pour retenir le deuxième pli en cas de prise double et autoriser le passage normal du pli dépilé en cas d'absence de prise double ce qui assure la non-détérioration des plis ouverts. En particulier, la mise en action de l'organe antiprise double au moment où le front avant du pli est pris en charge pour l'organe de transfert permet d'éviter l'ouverture d'un pli sous les effets antagonistes de l'organe de dépilage d'une part, agissant sur le front arrière du pli, et de l'organe antiprise double d'autre part, maintenant la partie avant de ce pli. Par ailleurs, le pli en prise double, s'il existe, est stoppé par l'organe de retenue. Il ne risque pas d'être détérioré puisqu'il n'est pas au contact de l'organe de dépilage.The device thanks to three detectors makes it possible to control the double anti-grip member to retain the second fold in the event of a double grip and to allow the normal passage of the depilated fold in the absence of a double grip, which ensures that the open folds are not damaged . In particular, the actuation of the double anti-socket member when the front edge of the fold is taken care of for the transfer member makes it possible to avoid the opening of a fold under the antagonistic effects of the member unstacking on the one hand, acting on the rear front of the fold, and the double anti-socket member on the other hand, maintaining the front part of this fold. Furthermore, the fold in double grip, if it exists, is stopped by the retaining member. There is no risk of it being damaged since it is not in contact with the unstacking member.
Lorsque la séparation des deux plis est constatée par un détecteur, ce pli est à son tour engagé dans l'organe de transfert.When the separation of the two folds is observed by a detector, this fold is in turn engaged in the transfer member.
L'invention s'étend également à un procédé de mise en oeuvre d'un tel dispositif de dépilage tel que défini aux revendications 6 et 7.The invention also extends to a method of implementing such a unstacking device as defined in
Les fonctions et avantages de ces caractéristiques du dispositif de dépilage apparaîtront à la lecture de la description suivante qui concerne un mode de réalisation préféré de l'invention illustré par la figure unique.The functions and advantages of these characteristics of the unstacking device will appear on reading the following description which relates to a preferred embodiment of the invention illustrated by the single figure.
Cette dernière représente un dispositif de dépilage conforme à l'invention en vue de dessus.The latter represents a destacking device according to the invention in top view.
Le dispositif se compose essentiellement :
- d'un chemin d'amenage sensiblement horizontal d'une pile de
plis 1 sur chant en butée contre une rive de taquage 2 sensiblement verticale, - d'un moyen de
dépilage 3 disposé devant la face du premier pli de lapile 1 et constitué d'un organe de translation à une vitesse V₁ perpendiculaire à lapile 1; il est constitué d'une courroie perforée 8 guidée et actionnée par poulies et associée à une tête à dépression 9 disposée derrière lacourroie 8, sur la trajectoire des plis, - d'un organe de retenue 4 constitué d'une tête à dépression agissant sur la face arrière du pli dépilé,
- d'un moyen de
transfert 5, à une vitesse V₂ supérieure à V₁, constitué de deuxcourroies
- a substantially horizontal feeding path of a stack of
folds 1 on edge abutting against a substantially vertical jogging edge 2, - unstacking means 3 disposed in front of the face of the first fold of the
stack 1 and consisting of a translation member at a speed V₁ perpendicular to thestack 1; it consists of aperforated belt 8 guided and actuated by pulleys and associated with a vacuum head 9 disposed behind thebelt 8, on the path of the folds, - a retaining member 4 consisting of a vacuum head acting on the rear face of the unstacked fold,
- a transfer means 5, at a speed V₂ greater than V₁, consisting of two
belts
La dépression de l'organe 4 est telle que son effort de retenue est inférieure à l'effort de translation par pincement du moyen de transfert 5.The depression of the member 4 is such that its retaining force is less than the translational force by pinching the transfer means 5.
Le moyen de dépilage 3 est disposé d'un côté du plan de la rive de taquage 2 et l'organe de retenue 4 et le moyen de transfert 5 de l'autre côté.The unstacking means 3 is arranged on one side of the plane of the jogging edge 2 and the retaining member 4 and the transfer means 5 on the other side.
Des détecteurs 6, 7, 13 constitués de capteurs photoélectriques sont disposés sur la trajectoire du pli dépilé.
Le premier détecteur 13 est situé en aval de la rive de taquage et à proximité de celle-ci.The
Le deuxième détecteur 7 est situé plus en aval mais de préférence en amont de la tête à dépression 4.The second detector 7 is located further downstream but preferably upstream of the vacuum head 4.
Le troisième détecteur 6 est le plus en aval; il est situé à proximité du point de pincement des courroies 10, 12 du moyen de transfert 5.The
Le moyen de dépilage 3 entraîne le pli à la vitesse V₁ jusqu'au point de pincement du moyen de transfert 5 où il est mis à la vitesse V₂. A titre d'exemple, V₁ peut être égale à 2m/s et V₂ à 3,2 m/s.The unstacking means 3 drives the fold at speed V₁ to the pinch point of the transfer means 5 where it is set to speed V₂. For example, V₁ can be equal to 2m / s and V₂ to 3.2m / s.
Le fonctionnement du dispositif géré grâce aux détecteurs 6, 7, 13 est le suivant :
- le premier pli est entraîné par le moyen de
dépilage 3, la tête à dépression 9 étant activée, - lorsque le front avant de ce pli est détecté par le capteur 7, la tête 4 est activée après une temporisation assurant la prise en charge du pli dépilé par le moyen de
transfert 5, - lorsque le front avant de ce pli est détecté par le
capteur 6, la tête 9 est désactivée.
- the first fold is driven by the unstacking means 3, the vacuum head 9 being activated,
- when the front edge of this fold is detected by the sensor 7, the head 4 is activated after a delay ensuring the handling of the fold unstacked by the transfer means 5,
- when the front edge of this fold is detected by the
sensor 6, the head 9 is deactivated.
Trois possibilités peuvent survenir :
- 1) Aucun second pli n'est en prise double et aucun second pli n'a avancé par friction ou accrochage devant le
capteur 13.
Dans ce cas, le front arrière du pli dépilé désocculte lecapteur 13, initialisant une temporisation à l'issue de laquelle la tête 9 est réactivée pour le dépilage du pli suivant.
Par ailleurs, le front arrière du pli dépilé désocculte le capteur 7, désactivant la tête 4. - 2) Aucun second pli n'est en prise double, mais un second pli a avancé par friction ou accrochage devant le
capteur 13.
Dans ce cas, le front arrière du pli dépilé désocculte le capteur 7, désactivant la tête 4 et initialisant une temporisation au terme de laquelle la tête 9 est réactivée pour le dépilage du pli suivant. - 3) Un second pli retenu par la tête 4 est en prise double, occultant les
capteurs 13 et 7.
Dans ce cas, le front arrière du pli dépilé désocculte lecapteur 6, initialisant une temporisation au terme de laquelle la tête 4 est désactivée et la tête 9 réactivée.
- 1) No second fold is in a double grip and no second fold has advanced by friction or hooking in front of the
sensor 13.
In this case, the rear edge of the depilated fold disables thesensor 13, initializing a time delay at the end of which the head 9 is reactivated for unstacking the next fold.
In addition, the rear edge of the depilated fold conceals the sensor 7, deactivating the head 4. - 2) No second ply is in a double grip, but a second ply has advanced by friction or hooking in front of the
sensor 13.
In this case, the rear edge of the depilated fold disables the sensor 7, deactivating the head 4 and initializing a time delay at the end of which the head 9 is reactivated for unstacking the next fold. - 3) A second fold retained by the head 4 is in double engagement, obscuring the
sensors 13 and 7.
In this case, the rear edge of the depilated fold disrupts thesensor 6, initializing a time delay at the end of which the head 4 is deactivated and the head 9 reactivated.
Le second pli est donc remis en vitesse. Son front avant occulte le capteur 6, ce qui a pour effet de réactiver la tête 4 et de désactiver la tête 9.The second fold is therefore put back in gear. Its front edge obscures the
Le front arrière du second pli permettra, selon l'état des capteurs 13 et 7, la réactivation de la tête 9 et la désactivation de la tête 4 en fonction des possibilités décrites ci-dessus et appliquées au troisième pli.The rear edge of the second fold will allow, depending on the state of the
Le choix des temporisations évoquées ci-dessus, celui de V₁ et V₂, enfin celui de la position des capteurs 13, 7, 6 et des organes 9, 4, 5, conduit à maximiser le débit d'objet dépilés en permettant un dépilage à intervalle constant entre plis quelle que soit leur longueur.The choice of timers mentioned above, that of V₁ and V₂, finally that of the position of the
Pour réaliser un prépositionnement des plis à dépiler, une chambre à faible dépression 11 est installée à côté du moyen de dépilage 3 en amont de celui-ci.To pre-position the folds to be unstacked, a
