Description

Domaine techniqueTechnical area

La présente invention concerne le domaine général de la mise en forme de tout ou partie de boîtes d'emballage à partir d'une feuille prédécoupée que l'on appelle "découpe à plat". L'invention concerne plus particulièrement un dispositif de dépilage et de localisation en 2D de telles découpes qui extrait une par une les découpes d'une pile, située dans un magasin, et dépose la découpe extraite à un endroit prédéterminé.The present invention relates to the general field of shaping all or part of packaging boxes from a precut sheet which is called "flat cutting". The invention relates more particularly to a device for unstacking and locating in 2D such cutouts which extracts one by one the cutouts from a stack, located in a store, and deposits the extracted cutout at a predetermined location.

Technique antérieurePrior art

Dans le domaine des machines de mise en forme de découpes à plat, on connait déjà de nombreux dispositif de transfert permettant de prendre une découpe depuis une pile dans un magasin en forme générale de pile et de la déposer sur des rails de transfert par exemple.In the field of machines for shaping flat blanks, numerous transfer devices are already known which make it possible to take a blank from a stack in a store in the general shape of a stack and to deposit it on transfer rails for example.

Ainsi, la demande de brevet internationale WO 93/11928 décrit un dispositif de saisie de découpes à plat disposées dans une pile placée dans une trémie de manière à avoir la dernière découpe à plat en bas de la pile. Ladite dernière découpe à plat est alors saisie et sortie de la trémie par le dispositif de saisie qui tourne dans un sens. Ledit dispositif de saisie est en outre associé à un dispositif auxiliaire qui tourne dans le sens opposé au sien et vient en contact avec une paroi de la dernière découpe à plat afin de l'extraire du dispositif de saisie et de commencer la mise en volume de l'emballage associé.So the international patent application WO 93/11928 describes a device for gripping flat blanks placed in a stack placed in a hopper so as to have the last flat blank at the bottom of the stack. Said last flat cut is then gripped and taken out of the hopper by the gripping device which rotates in one direction. Said gripping device is also associated with an auxiliary device which rotates in the opposite direction to its own and comes into contact with a wall of the last flat cut in order to extract it from the gripping device and to start setting up volume. associated packaging.

On connaît également un dispositif de transfert pour poste d'extraction et de dépose d'une découpe d'élément d'emballage tel que celui décrit dans la demande de brevet internationale WO 2013/045808 .There is also known a transfer device for a station for extracting and depositing a blank for a packaging element such as that described in the international patent application. WO 2013/045808 .

Ces différents dispositifs de saisie ou transfert sont complexes et onéreux car ils nécessitent souvent la mise œuvre d'un dispositif auxiliaire. En outre, lorsque la dernière découpe à plat quitte la pile ou le dispositif de saisie ou transfert, le positionnement de cette dernière n'est pas garanti et il est alors souvent nécessaire de repositionner ladite dernière découpe à plat avant toute mise en volume afin, par exemple, de réaliser les pliages suivant les lignes de pliage prévues.These different capture or transfer devices are complex and expensive because they often require the implementation work of an auxiliary device. In addition, when the last flat cut leaves the stack or the input or transfer device, the positioning of the latter is not guaranteed and it is then often necessary to reposition said last flat cut before any volume setting in order, for example, to make the folds along the fold lines provided.

Exposé de l'inventionStatement of the invention

La présente invention a donc pour but de proposer un dispositif de dépilage d'une découpe à plat de conception simple, facile à mettre en œuvre et permettant d'avoir à sa sortie une découpe parfaitement positionnée dans l'espace et apte à être évacuée en l'état vers une machine à emballer sans devoir être repositionnée.The present invention therefore aims to provide a device for unstacking a flat cut of simple design, easy to implement and allowing to have at its output a cut perfectly positioned in space and able to be evacuated in condition to a packing machine without having to be repositioned.

A cet égard, la présente invention a pour objet un dispositif de dépilage et de localisation en 2D de découpes à plat de forme globalement rectangulaire destinées à être mis en forme par une machine à emballer, ledit dispositif comportant :

  • un magasin comprenant au moins un plan de pose sensiblement horizontal apte à recevoir l'un des bords des découpes et une butée arrière basse et une butée arrière haute définissant un plan M sur lequel repose chaque découpe venant en appui sur lesdites butées arrières basse et haute,
  • une zone de dépose comprenant un plan P sensiblement horizontal sur lequel chaque découpe doit se trouver juste avant son évacuation de ladite zone de dépose et
  • un organe de préhension mobile comportant au moins un bras télescopique ou rotatif de type porte-ventouse muni d'une pluralité de ventouses à l'une de ses extrémités et apte à transférer la découpe située dans le plan M dudit magasin, au moins jusqu'au droit de ladite zone de dépose,
ledit dispositif étant remarquable en ce qu'il comporte des moyens de positionnement agencés pour positionner chaque découpe, lorsqu'elle est libérée des ventouses puis déplacée entre une position au droit de la zone de dépose et une position sur le plan P de cette dernière, selon deux directions perpendiculaires contenues dans ledit plan P et correspondant à la largeur et à la longueur de ladite découpe.In this regard, the subject of the present invention is a device for unstacking and locating in 2D flat cuts of generally rectangular shape intended to be shaped by a packaging machine, said device comprising:
  • a magazine comprising at least one substantially horizontal laying plane capable of receiving one of the edges of the cutouts and a low rear stop and a high rear stop defining a plane M on which each cut rests resting on said low and high rear stops ,
  • a deposit zone comprising a substantially horizontal plane P on which each cutout must be located just before it is removed from said deposit zone and
  • a movable gripping member comprising at least one telescopic or rotary arm of the suction cup type provided with a plurality of suction cups at one of its ends and capable of transferring the cutout located in the plane M of said magazine, at least up to to the right of said drop-off area,
said device being remarkable in that it comprises positioning means arranged to position each cutout, when it is released from the suction cups and then moved between a position in line with the depositing zone and a position on the plane P of the latter, in two perpendicular directions contained in said plane P and corresponding to the width and length of said cut.

On comprend bien qu'avec une telle configuration, à la sortie du dispositif 1 de dépilage et de localisation en 2D selon l'invention, les découpes sont extraites une à une du magasin et localisées dans l'espace à une position déterminée puisqu'au niveau de la zone de dépose, chaque découpe 2 est parfaitement positionnée dans le plan P de la zone de dépose et selon deux directions perpendiculaires. En outre, le dispositif selon l'invention est particulièrement intéressant car la localisation de la découpe s'effectue simultanément avec la fin du mouvement de la découpe de sorte que lorsqu'elle arrive sur le plan P, elle est correctement localisée dans l'espace.It is clear that with such a configuration, at the output of the device 1 for unstacking and localization in 2D according to the invention, the cutouts are extracted one by one from the store and located in space at a determined position since at level of the depositing zone, each cutout 2 is perfectly positioned in the plane P of the depositing zone and in two perpendicular directions. In addition, the device according to the invention is particularly advantageous because the location of the cutout takes place simultaneously with the end of the movement of the cutout so that when it arrives on the plane P, it is correctly located in space .

Selon un mode de réalisation préféré, l'organe de préhension comporte un bras télescopique du type porte-ventouse muni d'une pluralité de ventouses à l'une de ses extrémités et monté pivotant autour d'un premier axe de rotation sensiblement parallèle au plan M du magasin et au plan P de la zone de dépose, des moyens de soutien mobiles des découpes disposés de part et d'autre dudit bras, et une manivelle montée pivotante à l'une de ses extrémités autour d'un deuxième axe de rotation sensiblement parallèle audit premier axe de rotation et entrainée en rotation par un organe d'entrainement, ladite manivelle étant solidaire de manière coulissante par son extrémité libre à l'extrémité libre dudit bras pour entrainer ce dernier en rotation autour du premier axe de rotation.According to a preferred embodiment, the gripping member comprises a telescopic arm of the suction cup type provided with a plurality of suction cups at one of its ends and mounted pivoting about a first axis of rotation substantially parallel to the plane M of the magazine and in the plane P of the depositing zone, means for moving the blanks to be supported arranged on either side of said arm, and a crank pivotally mounted at one of its ends around a second axis of rotation substantially parallel to said first axis of rotation and driven in rotation by a drive member, said crank being slidably secured by its free end to the free end of said arm to drive the latter in rotation about the first axis of rotation.

Selon ce mode de réalisation, la zone de dépose est telle que son plan P est situé à l'arrière et au-dessus du magasin.According to this embodiment, the drop-off zone is such that its plane P is located at the rear and above the shop.

Les moyens de positionnement sont alors de préférence solidaires de la zone de dépose et comportent au moins :

  • une butée latérale fixe sur laquelle vient s'appuyer l'une des largeurs de chaque découpe sous la poussée d'un actionneur de cadrage latéral disposé en vis-à-vis de ladite butée latérale et agissant sur l'autre largeur de ladite découpe,
  • une butée longitudinale fixe sur laquelle vient s'appuyer l'une des longueurs de chaque découpe sous la poussée d'un actionneur de cadrage longitudinal disposé en vis-à-vis de ladite butée longitudinale et agissant sur l'autre longueur de ladite découpe.
The positioning means are then preferably integral with the depositing zone and comprise at least:
  • a fixed lateral stop on which one of the widths of each cut comes to bear under the thrust of a lateral framing actuator disposed opposite said lateral stop and acting on the other width of said cut,
  • a fixed longitudinal stop on which one of the lengths of each cut comes to bear under the thrust of a longitudinal framing actuator disposed opposite said longitudinal stop and acting on the other length of said cut.

Selon une variante de réalisation, l'organe de préhension comporte un bras télescopique du type porte-ventouse muni d'une pluralité de ventouses à l'une de ses extrémités et monté pivotant autour d'un premier axe de rotation sensiblement parallèle au plan M du magasin et au plan P de la zone de dépose, et une manivelle montée pivotante à l'une de ses extrémités autour d'un deuxième axe de rotation sensiblement parallèle audit premier axe de rotation et entrainée en rotation par un organe d'entraînement, ladite manivelle étant solidaire de manière coulissante par son extrémité libre à l'extrémité libre du bras pour entrainer ce dernier en rotation autour du premier axe de rotation.According to an alternative embodiment, the gripping member comprises a telescopic arm of the suction cup type provided with a plurality of suction cups at one of its ends and mounted pivoting about a first axis of rotation substantially parallel to the plane M of the magazine and at the plane P of the depositing area, and a crank pivotally mounted at one of its ends around a second axis of rotation substantially parallel to said first axis of rotation and driven in rotation by a drive member, said crank being slidably secured by its free end to the free end of the arm to cause the latter to rotate about the first axis of rotation.

Selon une première variante de réalisation, la zone de dépose est telle que le plan P est situé à l'arrière et en-dessous du magasin.According to a first alternative embodiment, the deposit area is such that the plane P is located at the rear and below the magazine.

Les moyens de positionnement sont alors avantageusement solidaires du bras et comportent au moins :

  • deux butées latérales agencées pour être disposées en vis-à-vis de part et d'autre de la découpe saisie par l'organe de préhension selon la largeur de ladite découpe.
  • deux butées longitudinales agencées pour être disposées en vis-à-vis de part et d'autre de la découpe saisie par l'organe de préhension selon la longueur de ladite découpe,
lesdites butées latérales et longitudinales étant montées pivotantes sur le bras et mises en mouvement respectivement par les actionneurs de cadrage latéral et de cadrage longitudinal entre une position écartée dans laquelle la découpe peut être dégagée et une position serrée dans laquelle, lorsque la découpe est dans le plan P, elle est localisée à l'endroit souhaité en vue de son évacuation de la zone de dépose.The positioning means are then advantageously secured to the arm and comprise at least:
  • two lateral stops arranged to be arranged opposite each other of the cutout gripped by the gripping member along the width of said cutout.
  • two longitudinal stops arranged to be arranged facing each other on the cutout gripped by the gripping member along the length of said cutout,
said lateral and longitudinal stops being pivotally mounted on the arm and set in motion respectively by the lateral framing and longitudinal framing actuators between a separated position in which the cut can be released and a tight position in which, when the cut is in the plan P , it is located at the desired location for its evacuation from the drop-off area.

De manière avantageuse, la butée arrière haute est décalée de ladite butée arrière basse vers l'arrière du magasin de sorte à avoir le plan M incliné vers l'arrière du magasin.Advantageously, the upper rear stop is offset from said lower rear stop towards the rear of the magazine so as to have the plane M inclined towards the rear of the magazine.

Selon une deuxième variante de réalisation, l'organe de préhension comporte un bras robotisé muni d'une pluralité de ventouses escamotables et le magasin est tel que son plan M est horizontal, l'arrière du magasin étant orienté vers le haut, ledit bras robotisé étant alors associé de préférence avec des moyens de positionnement identiques aux moyens de positionnement de la première variante précédemment décrite.According to a second alternative embodiment, the gripping member comprises a robotic arm provided with a plurality of retractable suction cups and the magazine is such that its plane M is horizontal, the rear of the magazine being oriented upwards, said robotic arm then preferably being associated with positioning means identical to the positioning means of the first variant previously described.

Le magasin 3 comporte un plan de pose 31 sensiblement horizontal et au moins une butée arrière basse 32 et une butée arrière haute 33 définissant un plan M sur lequel repose chaque découpe venant en appui sur lesdites butées arrières basse 32 et haute 33. De manière avantageuse, la butée arrière haute 33 est décalée de ladite butée arrière basse 32 vers l'arrière du magasin 3 de sorte à présenter les découpes 2 légèrement inclinées vers l'arrière du magasin 3, le plan M étant alors incliné vers l'arrière dudit magasin 3.The magazine 3 comprises a substantially horizontal laying plane 31 and at least one low rear stop 32 and a high rear stop 33 defining a plane M on which each cutout rests on said low rear 32 and high 33 stops. Advantageously , the upper rear stop 33 is offset from said lower rear stop 32 towards the rear of the magazine 3 so as to present the cutouts 2 slightly inclined towards the rear of the magazine 3, the plane M then being inclined towards the rear of said magazine 3.

La zone de dépose 4 est telle que son plan P est située à l'arrière et au-dessus du magasin 3.The deposit area 4 is such that its plane P is located at the rear and above the magazine 3.

Le dispositif 1 de dépilage et de localisation en 2D comporte en outre des moyens de positionnement 6 associés et avantageusement solidaires de la zone de dépose 4. Lesdits moyens de positionnement 6 sont agencés pour positionner chaque dépose 2, lorsqu'elle arrive sur le plan P de la zone de découpe 4, selon deux directions perpendiculaires contenues dans ledit plan P et correspondant à la largeur et à la longueur de ladite découpe 2.The device 1 for unstacking and localization in 2D also comprises positioning means 6 associated and advantageously integral with the depositing area 4. Said positioning means 6 are arranged to position each deposit 2, when it arrives on the plane P of the cutting area 4, in two perpendicular directions contained in said plane P and corresponding to the width and the length of said cutting 2.

Lesdits moyens de positionnement 6 comportent avantageusement au moins :

  • une butée latérale 61 fixe sur laquelle vient s'appuyer l'une des largeurs de chaque découpe 2, une fois transférée à la zone de dépose 4, sous la poussée d'un actionneur de cadrage latéral 62 disposé en vis-à-vis de ladite butée latérale 61 et agissant sur l'autre largeur de ladite découpe 2, les butée latérale fixe 61 et actionneur de cadrage latéral 62 étant avantageusement agencés pour être disposés au voisinage du milieu des largeurs de la découpe 2,
  • une butée longitudinale 63 fixe sur laquelle vient s'appuyer l'une des longueurs de chaque découpe 2, une fois transférée à la zone de dépose 4, sous la poussée d'un actionneur de cadrage longitudinal 64 disposé en vis-à-vis de ladite butée longitudinale 63 et agissant sur l'autre longueur de ladite découpe 2.
Said positioning means 6 advantageously comprise at least:
  • a fixed lateral stop 61 on which one of the widths of each cut 2 comes to bear, once transferred to the depositing zone 4, under the thrust of a lateral framing actuator 62 disposed opposite said lateral stop 61 and acting on the other width of said cut 2, the fixed lateral stop 61 and lateral framing actuator 62 being advantageously arranged to be arranged in the vicinity of the middle of the widths of cut 2,
  • a fixed longitudinal stop 63 on which one of the lengths of each cutout 2 comes to bear, once transferred to the depositing area 4, under the pressure of a longitudinal framing actuator 64 disposed opposite said longitudinal stop 63 and acting on the other length of said cutout 2.

Les moyens de positionnement 6 comportent de préférence deux ensembles butée longitudinale 63 - actionneur de cadrage longitudinal 64, chacun étant agencés pour être disposés à proximité des extrémités des longueurs de la découpe 2 (Cf. figure 6).The positioning means 6 preferably comprise two sets of longitudinal stop 63 - longitudinal framing actuator 64, each being arranged to be arranged near the ends of the lengths of the cutout 2 (cf. figure 6 ).

Les actionneurs de cadrage latéral 62 et de cadrage longitudinal 64 sont de préférence des vérins.The lateral framing 62 and longitudinal framing actuators 64 are preferably jacks.

L'organe de préhension 5 comporte un bras 51 télescopique avantageusement du type porte-ventouse muni d'une pluralité de ventouses 52 à l'une de ses extrémités et monté pivotant autour d'un premier axe de rotation 53 sensiblement parallèle au plan M du magasin 3 et au plan P de la zone de dépose 4, des moyens de soutien 54 mobiles des découpes 2 disposés de part et d'autre dudit bras 51, et une manivelle 55 montée pivotante à l'une de ses extrémités autour d'un deuxième axe de rotation 56 sensiblement parallèle audit premier axe de rotation 53 et entrainée en rotation par un organe d'entraînement, par exemple du type moteur électrique, non représenté sur les figures.The gripping member 5 comprises a telescopic arm 51 advantageously of the suction cup type provided with a plurality of suction cups 52 at one of its ends and mounted pivoting about a first axis of rotation 53 substantially parallel to the plane M of the magazine 3 and in plane P of the depositing zone 4, mobile support means 54 for the blanks 2 arranged on either side of said arm 51, and a crank 55 pivotally mounted at one of its ends around a second axis of rotation 56 substantially parallel to said first axis of rotation 53 and driven in rotation by a drive member, for example of the electric motor type, not shown in the figures.

On comprend bien que le bras 51 ne pourra également qu'être rotatif en étant monté pivotant autour d'un point à son extrémité libre et entrainé en rotation par un organe d'entraînement, par exemple du type moteur électrique, sans sortir du cadre de la présente invention.It will be understood that the arm 51 can also only be rotary by being mounted pivoting about a point at its free end and driven in rotation by a drive member, for example of the electric motor type, without leaving the frame of the present invention.

La manivelle 55 est solidaire de manière coulissante par son extrémité libre à l'extrémité libre du bras 51 pour entrainer ce dernier en rotation autour du premier axe de rotation 53, lorsqu'elle pivote autour du deuxième axe de rotation 56 grâce à l'action dudit organe d'entraînement.The crank 55 is slidably secured by its free end to the free end of the arm 51 to drive the latter in rotation about the first axis of rotation 53, when it pivots around the second axis of rotation 56 thanks to the action of said drive member.

Avec cette configuration, le dispositif 1 de dépilage et de localisation en 2D selon l'invention fonctionne selon un cycle comportant les étapes suivantes.With this configuration, the 2D unstacking and localization device 1 according to the invention operates according to a cycle comprising the following stages.

Tout d'abord, en référence à la figure 1, l'organe de préhension 5 vient saisir, à l'aide des ventouses 52, la découpe 2 située du côté arrière du magasin 3 en contact avec les butées basse 32 et haute 33, puis extrait cette découpe 2 du magasin 3. Pour supprimer l'effet ventouse entre deux découpes 2 adjacentes, un mouvement de va-et-vient du bras 51 est parfois nécessaire.First, with reference to the figure 1 , the gripping member 5 comes to grip, using the suction cups 52, the cutout 2 located on the rear side of the magazine 3 in contact with the bottom 32 and high 33 stops, then extracts this cutout 2 from the magazine 3. To remove the suction cup effect between two adjacent cutouts 2, a back-and-forth movement of the arm 51 is sometimes necessary.

Ensuite, la manivelle 55 pivote autour du deuxième axe de rotation 56 grâce à l'action dudit organe d'entraînement selon le sens R+ de manière à faire pivoter l'organe de préhension 5 afin de transférer la découpe 2 au droit de la zone de dépose 4 de la machine à emballer, conformément à la figure 2.Then, the crank 55 pivots around the second axis of rotation 56 by the action of said drive member in the direction R + so as to rotate the gripping member 5 in order to transfer the cutout 2 to the right of the area of removing 4 from the packaging machine, in accordance with figure 2 .

On désigne par "au droit de la zone de dépose 4" une position dans laquelle se trouve la découpe 2 lorsqu'elle est située dans un plan sensiblement parallèle au plan P de la zone de dépose 4 et distant de moins de 100 millimètres dudit plan P.The term "in line with the deposition zone 4" denotes a position in which the cutout 2 is located when it is situated in a plane substantially parallel to the plane P of the deposition zone 4 and spaced less than 100 millimeters from the said plane. P.

La manivelle 55 continue à pivoter pour faire monter le bras 51 et commencer à engager la découpe 2 entre les moyens de positionnement 6. Simultanément, on coupe le vide pour libérer la découpe 2 des ventouses 52 puis les moyens de soutien 54 poussent la découpe 2 pour l'amener jusqu'au plan P, conformément à la figure 3.The crank 55 continues to pivot to raise the arm 51 and begin to engage the cutout 2 between the positioning means 6. At the same time, the vacuum is cut to release the cutout 2 from the suction cups 52 then the support means 54 push the cutout 2 to bring it up to plane P , in accordance with the figure 3 .

Pendant le mouvement de poussée des moyens de soutien 54 de l'organe de préhension 5, les actionneurs de cadrage latéral 62 et de cadrage longitudinal 64 poussent ensuite la découpe 2 pour qu'elle vienne en contact respectivement des butées latérale 61 et longitudinale 63. Ainsi, lorsque la découpe 2 arrive sur le plan P de la zone de dépose 4, elle est correctement localisée dans l'espace conformément à la figure 4.During the pushing movement of the support means 54 of the gripping member 5, the lateral alignment 62 and longitudinal alignment 64 actuators then push the cutout 2 so that it comes into contact with lateral 61 and longitudinal 63 stops respectively. Thus, when the blank 2 arrives on the plane P of the depositing area 4, it is correctly located in the space in accordance with the figure 4 .

En référence à la figure 5, la manivelle 55 pivote autour du deuxième axe de rotation 56 grâce à l'action dudit organe d'entrainement selon le sens R-, opposé à R+, pour ramener le bras 51 dans la position représentée sur la figure 1 afin de reprendre une découpe 2 et recommencer un nouveau cycle. Au préalable, les actionneurs de cadrage latéral 62 et de cadrage longitudinal 64 reviennent dans leur position initiale pour libérer la découpe 2 et permettre son transfert et les moyens de soutien 54 reviennent également à leur position initiale une fois la découpe 2 évacuée de la zone de dépose 4.With reference to the figure 5 , crank 55 swivels around the second axis of rotation 56 by the action of said drive member in the direction R- , opposite to R + , to bring the arm 51 back to the position shown on the figure 1 to resume cutting 2 and start a new cycle. Beforehand, the lateral framing 62 and longitudinal framing actuators 64 return to their initial position to release the blank 2 and allow its transfer and the support means 54 also return to their initial position once the blank 2 has been removed from the area of remove 4.

On comprend bien qu'en sortie du dispositif 1 de dépilage et de localisation en 2D selon l'invention, les découpes 2 sont extraites une à une du magasin 3 et localisées dans l'espace à une position déterminée et fixe. En effet, à la sortie dudit dispositif 1, chaque découpe 2 est parfaitement positionnée dans un plan P de la zone de dépose 4 selon deux directions perpendiculaires.It will be understood that at the output of the device 1 for unstacking and localization in 2D according to the invention, the blanks 2 are extracted one by one from the magazine 3 and located in space at a determined and fixed position. Indeed, at the outlet of said device 1, each cutout 2 is perfectly positioned in a plane P of the depositing area 4 in two perpendicular directions.

Description d'autres modes de réalisationDescription of other embodiments

Dans une première variante de réalisation représentée aux figures 7 à 10, le dispositif 100 de dépilage et de localisation en 2D comporte au moins :

  • un magasin 300 identique au magasin 3 précédemment décrit et définissant un plan M avantageusement incliné vers l'arrière dudit magasin 300,
  • une zone de dépose 400, semblable à la zone de dépose 4 précédemment décrite, comprenant un plan P sensiblement horizontal situé à l'arrière et en-dessous du magasin 300 et
  • un organe de préhension 500 mobile configuré pour transférer la découpe 2 située dans le plan M à l'arrière dudit magasin 3, vers ladite zone de dépose 4, et
  • des moyens de positionnent 600 sont agencés pour positionner chaque découpe 2, lorsqu'elle est sur le plan P de la zone de découpe 400, selon deux directions perpendiculaires contenues dans ledit plan P et correspondant à la largeur et à la longueur de ladite découpe 2.
In a first alternative embodiment shown in figures 7 to 10 , the 2D unstacking and localization device 100 comprises at least:
  • a magazine 300 identical to magazine 3 previously described and defining a plane M advantageously inclined towards the rear of said magazine 300,
  • a drop zone 400, similar to the drop zone 4 previously described, comprising a substantially horizontal plane P situated at the rear and below the magazine 300 and
  • a movable gripping member 500 configured to transfer the blank 2 located in the plane M at the rear of said magazine 3, towards said deposit zone 4, and
  • positioning means 600 are arranged to position each cutout 2, when it is on the plane P of the cutting area 400, in two perpendicular directions contained in said plane P and corresponding to the width and the length of said cutting 2.

De façon analogue à l'organe de préhension 5 précédemment décrit, ledit organe de préhension 500 comporte un bras 501 télescopique avantageusement du type porte-ventouse muni d'une pluralité de ventouses 502 à l'une de ses extrémités et monté pivotant autour d'un premier axe de rotation 503 sensiblement parallèle au plan M du magasin 300 et au plan P de la zone de dépose 400, et une manivelle 504 montée pivotante à l'une de ses extrémités autour d'un deuxième axe de rotation 505 sensiblement parallèle audit premier axe de rotation 503 et entrainée en rotation par un organe d'entraînement, par exemple du type moteur électrique, non représenté sur les figures.Analogously to the gripping member 5 described above, said gripping member 500 comprises a telescopic arm 501 advantageously of the suction cup type provided with a plurality of suction cups 502 at one of its ends and mounted pivoting around a first axis of rotation 503 substantially parallel to the plane M of the magazine 300 and to the plane P of the depositing area 400, and a crank 504 pivotally mounted at one of its ends around a second axis of rotation 505 substantially parallel to said first axis of rotation 503 and driven in rotation by a drive member, for example of the electric motor type, not shown in the figures.

Ici aussi, on comprend bien que le bras 501 ne pourra également qu'être rotatif en étant monté pivotant autour d'un point à son extrémité libre et entrainé en rotation par un organe d'entraînement, par exemple du type moteur électrique, sans sortir du cadre de la présente invention.Here too, it is clear that the arm 501 can also only be rotatable by being pivotally mounted around a point at its free end and driven in rotation by a drive member, for example of the electric motor type, without going out of the scope of the present invention.

La manivelle 504 est également solidaire de manière coulissante par son extrémité libre à l'extrémité libre dudit bras 501 pour entrainer ce dernier en rotation autour du premier axe de rotation 503, lorsqu'elle pivote autour du deuxième axe de rotation 505 grâce à l'action dudit organe d'entraînement.The crank 504 is also slidably secured by its free end to the free end of said arm 501 to drive the latter in rotation about the first axis of rotation 503, when it pivots around the second axis of rotation 505 thanks to the action of said drive member.

De même, de façon analogue aux moyens de positionnement 6 précédemment décrits, les moyens de positionnement 600 comportent un ensemble butée latérale 601 - actionneur de cadrage latéral 602 et un ou de préférence deux ensemble(s) butée longitudinale 603 - actionneur de cadrage longitudinal 604 (Cf. figure 10).Likewise, similarly to the positioning means 6 described above, the positioning means 600 comprise a lateral stop assembly 601 - lateral framing actuator 602 and one or preferably two longitudinal stop assembly (s) 603 - longitudinal framing actuator 604 (Cf. figure 10 ).

Toutefois, pour cette variante de réalisation, les moyens de positionnement 600 sont solidaires du bras 501 et comportent au moins :

  • deux butées latérales 601 agencées pour être disposées en vis-à-vis de part et d'autre de la découpe 2 saisie par l'organe de préhension 500 selon la largeur de ladite découpe 2.
  • deux butées longitudinales 603 agencées pour être disposées en vis-à-vis de part et d'autre de la découpe 2 saisie par l'organe de préhension 500 selon la longueur de ladite découpe 2 (Cf. figure 10).
However, for this alternative embodiment, the positioning means 600 are integral with the arm 501 and comprise at least:
  • two lateral stops 601 arranged to be arranged opposite each other on the cutout 2 gripped by the gripping member 500 along the width of said cutout 2.
  • two longitudinal stops 603 arranged to be placed opposite each other on the cutout 2 gripped by the gripping member 500 along the length of said cutout 2 (Cf. figure 10 ).

Par ailleurs, les butées latérales 601 et longitudinales 603 sont montées pivotantes sur le bras 501 et sont mises en mouvement respectivement par les actionneurs de cadrage latéral 602 et de cadrage longitudinal 604 entre une position écartée dans laquelle la découpe 2 peut être dégagée et une position serrée dans laquelle, lorsque la découpe 2 est dans le plan P, elle est localisée à l'endroit souhaité en vue de son évacuation de la zone de dépose 400 (Cf. figure 9).Furthermore, the lateral 601 and longitudinal 603 stops are pivotally mounted on the arm 501 and are set in motion respectively by the lateral framing 602 and longitudinal framing actuators 604 between a separated position in which the cutout 2 can be released and a position tight in which, when the cutout 2 is in the plane P , it is located at the desired location with a view to its evacuation from the deposit area 400 (Cf. figure 9 ).

Avec cette variante de réalisation, le dispositif 100 de dépilage et de localisation en 2D selon l'invention fonctionne selon un cycle comportant les étapes suivantes.With this variant embodiment, the device 100 for unstacking and localization in 2D according to the invention operates according to a cycle comprising the following steps.

Tout d'abord, en référence à la figure 7, l'organe de préhension 500 vient saisir, à l'aide des ventouses 502, la découpe 2 située du côté arrière du magasin 300 en contact, puis extrait cette découpe 2 du magasin 3.First, with reference to the figure 7 , the gripping member 500 grasps, using the suction cups 502, the cutout 2 located on the rear side of the magazine 300 in contact, then extracts this cutout 2 from the magazine 3.

Ensuite, la manivelle 504 pivote autour du deuxième axe de rotation 505 grâce à l'action dudit organe d'entraînement, suivant le sens S+, de manière à faire pivoter l'organe de préhension 500 afin de transférer la découpe 2 au droit de la zone de dépose 400 de la machine à emballer, conformément à la figure 8.Then, the crank 504 pivots about the second axis of rotation 505 by the action of said drive member, in the direction S + , so as to rotate the gripping member 500 in order to transfer the cutout 2 to the right of the deposit area 400 of the packaging machine, in accordance with figure 8 .

La manivelle 504 continue à pivoter pour faire descendre le bras 501 et mettre en contact la découpe 2 avec le plan P. Simultanément, on coupe le vide pour libérer la découpe 2 des ventouses 502 afin que la découpe 2 soit retenue par les moyens de positionnement 600 qui la positionnent correctement de manière à ce que, lorsque la découpe 2 arrive sur le plan P de la zone de dépose 400, elle soit correctement localisée dans l'espace, conformément aux figures 9 et 10.The crank 504 continues to pivot to lower the arm 501 and bring the cutout 2 into contact with the plane P. Simultaneously, the vacuum is cut to release the blank 2 from the suction cups 502 so that the blank 2 is retained by the positioning means 600 which position it correctly so that, when the blank 2 arrives on the plane P of the area of deposit 400, it is correctly located in space, in accordance with Figures 9 and 10 .

Ensuite, les actionneurs de cadrage latéral 602 et de cadrage longitudinal 604 reviennent à leur position initiale pour libérer la découpe 2 et permettre son évacuation de la zone de dépose 400, puis la manivelle 505 pivote autour du deuxième axe de rotation 56 grâce à l'action dudit organe d'entrainement selon le sens opposé à S+, pour ramener le bras 501 dans la position représentée sur la figure 7 afin de reprendre une découpe 2 et recommencer un nouveau cycle.Then, the lateral framing 602 and longitudinal framing actuators 604 return to their initial position to release the blank 2 and allow its evacuation from the depositing area 400, then the crank 505 pivots around the second axis of rotation 56 thanks to the action of said drive member in the opposite direction to S + , to return the arm 501 to the position shown on the figure 7 to resume cutting 2 and start a new cycle.

Dans une seconde variante de réalisation non représentée, le dispositif de dépilage et de localisation en 2D diffère des dispositifs 1,100 précédemment décrits en ce que l'organe de préhension comporte un bras robotisé muni à son extrémité libre d'une pluralité de ventouses. Ledit bras robotisé est apte à transférer la découpe située dans le plan M dudit magasin vers le plan P de ladite zone de dépose, ledit magasin étant, par exemple ,tel que son plan P est horizontal, l'arrière du magasin étant orienté vers le haut. Ledit bras robotisé est alors équipé de ventouses escamotables et associé avec des moyens de positionnement identiques aux moyens de positionnement 600 précédemment décrits.In a second embodiment not shown, the unstacking and localization device in 2D differs from the devices 1,100 previously described in that the gripping member comprises a robotic arm provided at its free end with a plurality of suction cups. Said robotic arm is capable of transferring the cutout located in the plane M of said magazine to the plane P of said depositing zone, said magazine being, for example, such that its plane P is horizontal, the rear of the magazine being oriented towards the high. Said robotic arm is then equipped with retractable suction cups and associated with positioning means identical to the positioning means 600 previously described.
