Description

Domaine de l'inventionField of the invention

La présente invention concerne le domaine du dépilage d'objets plans empilés dans un chargeur, en particulier de feuilles en carton découpées, de feuilles semi-rigides en PVC ou encore de circuits imprimés empilés dans un chargeur et du transfert de ces objets entre le chargeur et un tapis de transfert.The present invention relates to the field of unstacking flat objects stacked in a charger, in particular cut cardboard sheets, semi-rigid PVC sheets or even printed circuits stacked in a charger and the transfer of these objects between the charger and a transfer mat.

De tels dépileurs comportent un mécanisme d'entraînement d'une ventouse qui est alternativement approchée, mise en contact puis écartée de la pile de feuilles. La ventouse est plaquée sur la feuille supérieure de la pile, et entraîne ensuite la feuille supérieure pour l'éloigner de la pile avant de la déposer sur une autre zone de travail, par exemple sur un convoyeur à dépression.Such unstackers comprise a mechanism for driving a suction cup which is alternately approached, brought into contact and then moved away from the stack of sheets. The suction cup is pressed against the top sheet of the stack, and then drives the top sheet away from the stack before depositing it on another work area, for example on a vacuum conveyor.

Afin de permettre un fonctionnement à de très grandes cadences avec une précision et une reproductibilité de la dépose, il est important de synchroniser les vitesses de prise et de dépose de la feuille, et donc de démarrer avec une vitesse nulle, la position de la feuille sur le chargeur étant fixe, et une vitesse égale à celle de convoyeur à bande. Ceci implique donc une forte accélération et une grande précision des vitesses de déplacement pendant cette étape de transfert.In order to allow operation at very high speeds with precision and reproducibility of the deposit, it is important to synchronize the pick-up and deposit speeds of the sheet, and therefore to start with zero speed, the position of the sheet on the feeder being fixed, and a speed equal to that of belt conveyor. This therefore implies a strong acceleration and a high precision of the displacement speeds during this transfer step.

On connaît dans l'état de la technique la demande de brevet US2013/170928 décrivant un système de palettes une piste sans fin d'un bout à l'autre d'une zone d'impression et d'une zone de manipulation. Dans la zone d'impression, les palettes sont temporairement regroupées de manière à supporter et à déplacer un support d'impression au cours de l'impression à une vitesse sensiblement constante. Dans la zone de manipulation, les palettes sont espacées les unes des autres lorsqu'elles reviennent vers la zone d'impression sans supporter aucun support d'impression. US2013/170928 décrit en outre le préambule de la revendication 1.We know in the state of the art the patent application US2013/170928 describing a system of pallets an endless track from one end to the other of a printing area and a handling area. In the printing area, the paddles are temporarily grouped together to support and move a print medium during printing at a substantially constant speed. In the handling area, the pallets are spaced from each other when they are return to the print area without supporting any print media. US2013/170928 further describes the preamble of claim 1.

La demande de brevet internationale WO2017021103 décrit un procédé pour retirer des feuilles de placage d'une pile, selon lequel une première feuille d'une pile est retirée de la pile au moyen d'un dispositif aspirant d'un préhenseur mobile et la feuille est ensuite transférée sur un convoyeur puis transportée, ledit procédé étant caractérisé en ce qu'après avoir été soulevée par un premier préhenseur, la feuille est remise à un second préhenseur qui la transfère au convoyeur.The international patent application WO2017021103 describes a method for removing veneer sheets from a stack, in which a first sheet of a stack is removed from the stack by means of a suction device of a movable gripper and the sheet is then transferred onto a conveyor and then transported, said method being characterized in that after having been lifted by a first gripper, the sheet is delivered to a second gripper which transfers it to the conveyor.

Le brevet français FR2623473 décrit un dispositif de transfert d'une pile de flans pour cartons depuis une palette jusqu'au magasin d'une machine à emballer dans des cartons, dans lequel les flans en carton sont disposés verticalement l'un à côté de l'autre, en particulier pour l'industrie du tabac, caractérisé par les particularités suivantes :

  2. b) dans la position verticale du chariot de déchargement et donc dans la position horizontale de la fourche de déchargement, les dents de cette dernière peuvent coulisser pour venir sous la pile dans les intervalles entre les planches de la face supérieure de la palette
  3. c) un mécanisme d'entraînement fait coulisser le chariot de déchargement, et donc les dents, dans la direction des intervalles entre les planches de la face supérieure de la palette
et d) dans le chariot de déchargement est incorporé un mécanisme de transport (pour le transfert des flans individuels depuis le chariot de déchargement, vers le magasin.The French patent FR2623473 describes a device for transferring a stack of carton blanks from a pallet to the magazine of a carton-packing machine, in which the carton blanks are arranged vertically next to each other, particular for the tobacco industry, characterized by the following features:
  1. a) an unloading carriage, which can pivot about a horizontal axis to pass from a substantially vertical position to a substantially horizontal position, comprises an unloading fork which is movable along the unloading carriage
  2. b) in the vertical position of the unloading trolley and therefore in the horizontal position of the unloading fork, the teeth of the latter can slide to come under the stack in the gaps between the boards of the upper face of the pallet
  3. c) a drive mechanism slides the unloading carriage, and thus the tines, in the direction of the gaps between the boards of the upper side of the pallet
and d) in the unloading carriage there is incorporated a transport mechanism (for the transfer of the individual blanks from the unloading carriage, to the magazine.

Inconvénients de l'art antérieurDisadvantages of the prior art

Les solutions de l'art antérieur donnent globalement satisfaction, mais sont très délicates à régler et sont très sensibles aux variations de vitesse du tapis convoyeur. Par ailleurs, elles ne tolèrent aucun changement entre deux articles consécutifs.The solutions of the prior art give overall satisfaction, but are very tricky to adjust and are very sensitive to variations in the speed of the conveyor belt. Moreover, they do not tolerate any change between two consecutive articles.

Par ailleurs, les solutions de l'art antérieur ne permettent pas d'individualiser les déplacements, pour appliquer une légère correction de vitesse à l'un des flans transférer car tous les supports de ventouses sont entraînés par le même mécanisme.Furthermore, the solutions of the prior art do not make it possible to individualize the movements, in order to apply a slight speed correction to one of the blanks to be transferred, since all the suction cup supports are driven by the same mechanism.

Description d'ensembleGeneral Description

La figure 1 représente une vue d'ensemble de la partie amont d'une installation de cartonnage. Elle comprend de manière connue une unité d'alimentation (100) pour l'approvisionnement et le chargement des piles de flans (101) et un convoyeur (200) des flans dépilés (301).The figure 1 shows an overview of the upstream part of a cartoning installation. It comprises, in known manner, a supply unit (100) for supplying and loading the stacks of blanks (101) and a conveyor (200) of the unstacked blanks (301).

Le transfert entre la pile de flans (102) du dépileur (110) sur le convoyeur à dépression (200) est réalisé par une unité de transfert (300) objet de l'invention.The transfer between the stack of blanks (102) of the destacker (110) on the vacuum conveyor (200) is carried out by a transfer unit (300) which is the subject of the invention.

Le rôle de cette unité de transfert (300) est de prendre le flan (111) présent à la surface supérieure du dépileur (110), à vitesse horizontale nulle pour éviter tout glissement par rapport au flan suivant, qui pourrait occasionner des éraflures ou dégradation de l'état de surface, s'il s'agit par exemple de feuilles vernis.The role of this transfer unit (300) is to take the blank (111) present at the upper surface of the destacker (110), at zero horizontal speed to avoid any slippage with respect to the following blank, which could cause scratches or damage. the surface condition, if it is for example varnish sheets.

Lors de la prise de contact entre la ventouse de l'unité de transfert (300) et le flan supérieur (111), il est usuel d'appliquer d'abord, avant tout déplacement vers le convoyeur (200), une légère angulation pour faciliter le décollage par rapport au flan suivant et compenser l'effet de collage électrostatique. Pour cela, l'unité de transfert commande un déplacement angulaire de tête d'aspiration pour modifier le plan de contact par rapport au plan parallèle au plan du convoyeur de quelques degrés, selon un exemple de solution décrit dans ce qui suit.When making contact between the suction cup of the transfer unit (300) and the upper blank (111), it is customary to first apply, before any movement towards the conveyor (200), a slight angulation to facilitate separation from the next blank and compensate for the electrostatic sticking effect. For this, the transfer unit controls an angular displacement of the suction head to modify the plane of contact with respect to the plane parallel to the plane of the conveyor by a few degrees, according to an example of a solution described below.

Le flan (111) détaché de la pile du dépileur (102) passe ensuite d'une vitesse horizontale nulle à une horizontale identique à celle du convoyeur à dépression (300). L'unité de transfert (300) commande alors la libération du flan, lorsque la vitesse relative entre la ventouse et le convoyeur est nulle, pour appliquer le flan transféré sur le convoyeur. On entend dans le présent brevet par « horizontal » le plan formé par la surface supérieure du tapis aspirant du convoyeur (200).The blank (111) detached from the stack of the destacker (102) then passes from zero horizontal speed to a horizontal speed identical to that of the vacuum conveyor (300). The transfer unit (300) then controls the release of the blank, when the relative speed between the suction cup and the conveyor is zero, to apply the transferred blank to the conveyor. In the present patent, the term "horizontal" means the plane formed by the upper surface of the suction belt of the conveyor (200).

Il est à noter que cette cinématique précise doit être réalisée sur une installation fonctionnant à des cadences très élevées, typiquement 10.000 flans par heure, et pendant des périodes longues, typiquement plusieurs heures, sans disfonctionnement ni interruption, et avec un minimum de temps de calage et de réglage initial.It should be noted that this precise kinematics must be carried out on an installation operating at very high speeds, typically 10,000 blanks per hour, and for long periods, typically several hours, without malfunction or interruption, and with a minimum of setting time. and initial setting.

L'unité d'alimentation (100) comporte un poste de chargement (120) constitué par un plateau de chargement (121) dont le fond est constitué d'une fourche (122) présentant plusieurs dents reliées à l'arrière par une traverse (123). Les dents sont espacées par des intervalles correspondant à l'espacement des bandes (131) d'un convoyeur à bandes (130).The supply unit (100) comprises a loading station (120) consisting of a loading plate (121) the bottom of which consists of a fork (122) having several teeth connected at the rear by a crosspiece ( 123). The teeth are spaced at intervals corresponding to the spacing of the belts (131) of a conveyor belt (130).

Ce convoyeur à bandes (130) assure le déplacement des piles de flans entre le poste de chargement (120) et le dépileur (110).This belt conveyor (130) moves the stacks of blanks between the loading station (120) and the destacker (110).

Le plateau (121) est mobile verticalement par rapport à un bâti motorisé (132) entre une position haute de chargement, permettant à un opérateur de déposer une pile de flans (101) sans se baisser, et une position basse où le bas de la pile vient reposer sur les bandes (131) du convoyeur à bandes (130).The plate (121) is vertically movable relative to a motorized frame (132) between a high loading position, allowing an operator to deposit a stack of blanks (101) without bending down, and a low position where the bottom of the stack comes to rest on the bands (131) of the belt conveyor (130).

Lorsque la pile de flans du dépileur (110) est complétement transférée, le convoyeur à bandes (130) assure le déplacement d'une nouvelle pile dans le dépileur (110).When the stack of blanks from the destacker (110) is completely transferred, the belt conveyor (130) moves a new stack into the destacker (110).

Le dépileur (110) comporte également un plateau (112) constitué par une traverse munie de dents espacées pour s'intercaler entre les bandes (131) du convoyeur à bandes (130). Ce plateau (112) est mobile par rapport à un bâti motorisé (113) entre une position basse, inférieure à la surface des bandes (131), où il peut venir en contact avec la surface inférieure d'une pile présente sur le convoyeur à bandes (130), et des positions de travail où le plateau (112) est remonté séquentiellement pour que le flan supérieur (111) soit positionné dans le plan horizontal de prise par une ventouse de l'unité de transfert (200).The unstacker (110) also comprises a plate (112) constituted by a crosspiece provided with teeth spaced apart to fit between the strips (131) of the belt conveyor (130). This plate (112) is movable relative to a motorized frame (113) between a low position, lower than the surface of the strips (131), where it can come into contact with the lower surface of a stack present on the conveyor strips (130), and working positions where the plate (112) is raised sequentially so that the upper blank (111) is positioned in the horizontal gripping plane by a suction cup of the transfer unit (200).

Description détaillée d'un support de ventouseDetailed description of a suction cup holder

La figure 3 représente une vue schématique d'un exemple de réalisation d'un équipage mobile commandant la trajectoire et l'orientation de la ventouse (430).The picture 3 represents a schematic view of an embodiment of a moving assembly controlling the trajectory and orientation of the suction cup (430).

La ventouse (430) est actionnée par un équipage formé par un chariot aval (410) et un chariot amont (420).The suction cup (430) is actuated by a crew formed by a downstream carriage (410) and an upstream carriage (420).

Les deux chariots (410, 420) sont de manière connue équipés d'aimants permanents couplés électro-magnétiquement avec les bobines électriques équipant le stator (250), pour former un couple de moteurs linéaires.The two carriages (410, 420) are in known manner equipped with permanent magnets electromagnetically coupled with the electric coils equipping the stator (250), to form a pair of linear motors.

Le pilotage de l'alimentation des bobines statoriques permet de commander le déplacement indépendant de chacun des chariots (410, 420) constituant un équipage mobile. Ce pilotage permet de commander la vitesse et l'amplitude du déplacement de chacun des chariots (410, 420), le sens du déplacement, et bien sur le déplacement relatif du chariot aval (410) de l'équipage mobile par rapport au chariot amont (420) du même équipage mobile.Controlling the supply of the stator coils makes it possible to control the independent movement of each of the carriages (410, 420) constituting a moving assembly. This control makes it possible to control the speed and the amplitude of the movement of each of the carriages (410, 420), the direction of the movement, and of course the relative movement of the downstream carriage (410) of the mobile assembly with respect to the upstream carriage (420) of the same mobile assembly.

La ventouse (430) est supportée par une platine basculante (431) reliée par un pivot au bras inférieur (424) d'une structure formant un parallélogramme déformable. Ce parallélogramme déformable est formé par un bras supérieur (421) fixé sur le chariot amont (420). Le bras inférieur (424) et le bras supérieur (421) sont reliés par deux bras parallèles (422, 423) par l'intermédiaire de pivots.The suction cup (430) is supported by a tilting plate (431) connected by a pivot to the lower arm (424) of a structure forming a deformable parallelogram. This deformable parallelogram is formed by an upper arm (421) fixed to the upstream carriage (420). The lower arm (424) and the upper arm (421) are connected by two parallel arms (422, 423) via pivots.

Un autre point de la platine basculante (431) est relié par un pivot à une bielle (411) au chariot aval (410).Another point of the tilting plate (431) is connected by a pivot to a connecting rod (411) to the downstream carriage (410).

La déformation du parallélogramme déformable reliant la ventouse (430) au chariot amont (420) détermine la distance entre la ventouse (430) et le rail (250) et permet de commander le positionnement vertical de la ventouse (430).The deformation of the deformable parallelogram connecting the suction cup (430) to the upstream carriage (420) determines the distance between the suction cup (430) and the rail (250) and makes it possible to control the vertical positioning of the suction cup (430).

Le déplacement relatif du chariot amont (420) par rapport au chariot aval (410) modifie l'inclinaison de la platine basculante (431).The relative movement of the upstream carriage (420) with respect to the downstream carriage (410) modifies the inclination of the tilting plate (431).

Description détaillée du support d'une ligne de ventousesDetailed description of the support for a line of suction cups

La figure 2bis représente une vue en perspective de la liaison entre une ligne de ventouses (430) montées sur une tige cannelée ou carrée (460). Les ventouses sont fixées sur la tige (460) par une bride (465) qui peut être déplacé le long de la tige (460) pour adapter la position latérale de la ou des ventouses (430) aux dimensions de flan à déplacés, puis serrés sur la tige (460). Toutes les ventouses (430) montées sur une même tige pivotent en même temps.The Figure 2bis shows a perspective view of the connection between a line of suction cups (430) mounted on a splined or square rod (460). The suction cups are fixed on the rod (460) by a flange (465) which can be moved along the rod (460) to adapt the lateral position of the suction cup(s) (430) to the dimensions of the blank to be moved, then tightened on the rod (460). All the suction cups (430) mounted on the same rod pivot at the same time.

La rotation de la tige est assurée par la platine basculante (431) qui est articulée, de part et d'autre de la tige (460), par rapport à une paire de bras avant (422, 442) et de bras arrière (424, 444). Les autres extrémités de ses bras sont articulées par rapport à la platine supérieure (421), l'ensemble formant une paire de parallélogrammes déformables.The rotation of the rod is ensured by the tilting plate (431) which is articulated, on either side of the rod (460), with respect to a pair of front arms (422, 442) and rear arms (424 , 444). The other ends of its arms are articulated with respect to the upper plate (421), the assembly forming a pair of deformable parallelograms.

Une bielle (450) est positionnée à l'intérieur du parallélogramme et a pour fonction d'amplifier la rotation de la ventouse (430) quand le parallélogramme arrive en bout de course dans un sens.A connecting rod (450) is positioned inside the parallelogram and has the function of amplifying the rotation of the suction cup (430) when the parallelogram reaches the end of its travel in one direction.

Description d'un exemple de cinématiqueDescription of an example of kinematics

Les figures 3 à 9 représentent un exemple non limitatif de cinématique de prise et dépose d'un flan (111) présent, au dépôt, au sommet de la pile du dépileur.The figures 3 to 9 represent a non-limiting example of kinematics for picking up and depositing a blank (111) present, at the deposit, at the top of the stack of the destacker.

La figure 2 représente l'équipage en position d'arrivée de la ventouse, en approche du dépileur. Le circuit de pilotage électrique commande le ralentissement du chariot aval (410) par rapport au chariot amont (420).The figure 2 represents the crew in the arrival position of the suction cup, approaching the unstacker. The electric control circuit controls the slowing down of the downstream carriage (410) relative to the upstream carriage (420).

La figure 3 représente la position lors de la mise en contact de la ventouse (430) avec le flan supérieur (111). Le circuit de pilotage continue à commander un ralentissement du chariot aval (410) par rapport au chariot amont (420) et commande l'activation du vide dans le conduit relié à la ventouse active (430). Le déplacement horizontal de la ventouse est nul.The picture 3 represents the position when the suction cup (430) is brought into contact with the upper blank (111). The control circuit continues to control a slowing down of the downstream carriage (410) relative to the upstream carriage (420) and controls the activation of the vacuum in the conduit connected to the active suction cup (430). The horizontal displacement of the suction cup is zero.

La figure 4 représente l'étape suivante de maintien de la ventouse (430) à un point fixe tout en continuant l'avance des chariots (410, 420). Le circuit de pilotage commande le maintien du ralentissement du chariot aval (410) par rapport au chariot amont (420).The figure 4 represents the next step of maintaining the suction cup (430) at a fixed point while continuing to advance the carriages (410, 420). The control circuit controls the maintenance of the slowing down of the downstream carriage (410) relative to the upstream carriage (420).

L'étape suivante est illustrée par la figure 5, représentant le décollement du flan (111) par rapport à la pile du dépileur. On continue à ralentir le chariot aval (410) par rapport au chariot amont (420), les deux continuant à avancer.The next step is illustrated by the figure 5 , representing the detachment of the blank (111) relative to the stack of the destacker. The downstream carriage (410) continues to be slowed relative to the upstream carriage (420), both continuing to advance.

La figure 6 représente le déplacement vertical du flan (111) maintenu par la ventouse (430).The figure 6 represents the vertical displacement of the blank (111) held by the suction cup (430).

L'étape suivante représentée en figure 7 correspond à l'accélération de l'équipage mobile pour passer d'une vitesse nulle à une vitesse correspondant à celle du convoyeur, pour synchroniser les vitesses.The next step represented in figure 7 corresponds to the acceleration of the moving assembly to pass from zero speed to a speed corresponding to that of the conveyor, to synchronize the speeds.

La figure 8 représente la dépose du flan (111) sur le convoyeur (300).The figure 8 represents the placement of the blank (111) on the conveyor (300).
