Description

Procédé et dispositif d'introduction de plaques pour une machine de transformation de plaques de carton ondulé ou à micro-cannelure.  Method and apparatus for introducing plates for a corrugated or micro-corrugated board converting machine
1. Domaine de l'invention  1. Field of the invention
L'invention concerne le domaine des machines de transformation d'éléments en plaque, et plus particulièrement un procédé d'introduction d'éléments en plaque de carton ondulé ou à micro-cannelure et un dispositif pour la mise en œuvre du procédé.  The invention relates to the field of plate element processing machines, and more particularly to a method for introducing elements made of corrugated board or microstrip board and a device for implementing the method.
2. Art antérieur 2. Prior Art
On connaît des procédés et dispositifs d'introduction d'éléments en plaques (ci après plaques) pour des machines de transformation desdites plaques. Entre les différentes machines, ces plaques de grandes dimensions sont transportées par piles de grande hauteur placées sur des palettes.  Methods and devices for introducing plate elements (hereinafter plates) for processing machines of said plates are known. Between the different machines, these large plates are transported by high-pile piles placed on pallets.
Une première catégorie de ces dispositifs nommés feeders utilise un paquet de plaques dont la plaque inférieure est prélevée par un dispositif de transport comme par exemple une plaque aspirante, des courroies ou rouleau vacuum. Dans le but de ne prendre qu'une plaque à la fois, ces dispositifs sont munis d'une jauge qui est réglée à une valeur empirique d'environ 1.5 fois la hauteur de l'élément en plaque à prendre.  A first category of these devices called feeders uses a pack of plates whose lower plate is taken by a transport device such as for example a suction plate, belts or vacuum roller. In order to take only one plate at a time, these devices are provided with a gauge which is set to an empirical value of approximately 1.5 times the height of the plate element to be taken.
Ces dispositifs, particulièrement utilisés pour l'introduction de plaques de carton ondulé, présentent plusieurs inconvénients dont la difficulté à régler la hauteur de la jauge. Si elle est trop haute, on risque d'avoir deux plaques qui partent et cela va occasionner un bourrage en aval dans la machine de transformation, et si elle est trop basse, on risque de coincer la plaque ou de fortement la détériorer. Ces inconvénients sont d'autant plus flagrants que l'épaisseur des plaques est faible.  These devices, particularly used for the introduction of corrugated cardboard plates, have several drawbacks including difficulty in adjusting the height of the gauge. If it is too high, there is a risk of having two plates leaving and this will cause a jam downstream in the processing machine, and if it is too low, there is a risk of jamming the plate or strongly deteriorate it. These disadvantages are all the more obvious as the thickness of the plates is low.
D'autre part, il est fréquent que la jauge endommage les plaques à introduire, en particulier sur leur bord frontal. Le fait de prendre les plaques par le bas implique également un frottement conséquent entre la plaque qui s'introduit et la suivante. Il n'est pas rare de constater des marques sur les plaques dues à ce frottement, ce qui peut par exemple détériorer une impression réalisée sur la surface de la plaque, lorsque l'introduction concerne une machine de traitement postimpression, comme par exemple une machine de découpe. Un inconvénient supplémentaire provient du fait que la précision d'introduction des plaques est fortement dépendante de la hauteur du paquet. Pour pallier à ce problème et conserver une hauteur constante de paquet, il est d'usage d'avoir un dispositif de pré-introduction des plaques nommé communément pré-feeder, qui partant d'une pile constitue une nappe qui vient charger le paquet du dispositif d'introduction des plaques. Ce dispositif assure l'alimentation en continu, même lors de changements de pile. Il est également responsable d'évacuer les quelques dernières plaques de la pile qui ont été endommagées lors du transport de la pile, en particulier pour des plaques de carton ondulé. La création de la nappe est elle aussi faite à l'aide d'une jauge qui elle aussi peut potentiellement endommager la plaque. On the other hand, it is common that the gauge damages the plates to introduce, especially on their front edge. Taking the plates from the bottom also involves a significant friction between the plate that is introduced and the next. It is not uncommon to note marks on the plates due to this friction, which can for example deteriorate an impression made on the surface of the plate, when the introduction concerns a post-impression processing machine, such as for example a machine cutting. An additional disadvantage arises from the fact that the precision of introduction of the plates is highly dependent on the height of the package. To overcome this problem and maintain a constant package height, it is customary to have a pre-introduction device plates commonly called pre-feeder, which from a stack is a sheet that comes load the package of plate introduction device. This device provides continuous power, even during battery changes. It is also responsible for evacuating the last few plates of the battery that have been damaged during the transport of the battery, especially for corrugated sheets. The creation of the sheet is also made using a gauge which also can potentially damage the plate.
Une seconde catégorie de dispositifs nommés margeurs prélève les plaques au sommet de la pile, ce qui permet d'éviter les dégâts occasionnés par la jauge du feeder. En revanche ce genre de dispositif ne peut pas assurer à la fois l'alimentation en continu et l'évacuation des dernières plaques de la pile endommagées par le transport, en particulier pour les plaques de carton ondulé. De plus pour assurer l'alimentation en continu, il nécessite une palette spéciale.  A second category of devices called feeders picks the plates at the top of the stack, which avoids the damage caused by the feeder gauge. On the other hand, this kind of device can not ensure both the continuous supply and the evacuation of the last plates of the pile damaged by the transport, in particular for corrugated board plates. In addition to ensure continuous feeding, it requires a special palette.
De ce fait, cette catégorie de dispositif n'est en pratique pas utilisée dans le carton ondulé, plus personne ne voulant avoir des palettes qui doivent être de tailles très variables pour s'adapter aux dimensions des différentes plaques.  Therefore, this category of device is in practice not used in corrugated cardboard, no one wanting to have pallets that must be of very variable sizes to adapt to the dimensions of the different plates.
L'état de l'art ne propose donc pas de procédé ou dispositif d'introduction de plaques permettant simultanément une alimentation en continu, l'évacuation des plaques en bas de chaque pile, sans risque de dommage aux plaques dû aux différentes jauges.  The state of the art therefore does not propose a method or device for introducing plates simultaneously allowing a continuous supply, the evacuation of the plates at the bottom of each stack, without risk of damage to the plates due to different gauges.
De plus l'état de l'art des feeders convient très mal aux machines d'impression jet d'encre. En effet, pour les raisons de fiabilité et économiques, il est avantageux d'avoir la laize la plus petite possible, en particulier pour une machine « single-pass ». Pour cette raison dans ce genre de machine, la plaque est mise lors de grand format avec le côté long dans le sens de la poussée. Les pré-feeder et feeder selon l'état de l'art deviennent alors extrêmement longs et il devient difficile de placer la machine dans une usine existante.  In addition, the state of the art feeders is very poorly suited to inkjet printing machines. Indeed, for reasons of reliability and economic, it is advantageous to have the smallest width possible, especially for a machine "single-pass". For this reason in this kind of machine, the plate is put in large format with the long side in the direction of thrust. The pre-feeder and feeder according to the state of the art then become extremely long and it becomes difficult to place the machine in an existing factory.
Pour l'impression numérique il est essentiel que le bord de la plaque ne soit pas détérioré, car un défaut sur le bord pourrait conduire à un contact entre la plaque et les têtes d'impression qu'il faut à tout prix éviter pour éviter d'endommager les têtes d'impression.  For digital printing it is essential that the edge of the plate is not damaged because a defect on the edge could lead to a contact between the plate and the print heads that must be avoided at all costs to avoid 'damage the printheads.
3. Objectifs de l'invention 3. Objectives of the invention
L'invention a notamment pour objectif de pallier tout ou partie de ces inconvénients de l'art antérieur. Plus précisément, un objectif d'au moins un des modes de réalisation de l'invention est de proposer un procédé et un dispositif d'introduction de plaques pour une machine de traitement, qui n'endommage pas le bord ou la surface des plaques ni par des jauges, ni par un frottement excessif. Au moins un des modes de mise en œuvre de l'invention assure une introduction avec une alimentation continue. Au moins un mode de mise en œuvre de l'invention permet l'évacuation des plaques situées à la base des la pile. The invention particularly aims to overcome all or part of these disadvantages of the prior art. More specifically, it is an objective of at least one of the embodiments of the invention to provide a method and a device for introducing plates for a processing machine, which does not damage the edge or surface of the plates or by gauges, or by excessive friction. At least one of the embodiments of the invention provides an introduction with a continuous supply. At least one embodiment of the invention allows the evacuation of the plates at the base of the stack.
Tout en étant utilisable pour l'introduction de plaques de tout type de plaques pour des machines de transformation classiques de toutes sortes (par exemple l'impression flexo, la découpe), un dispositif selon l'invention est particulièrement adapté pour l'introduction de plaques de carton ondulé ou à micro-cannelures pour une machine d'impression numérique conformément au procédé selon l'invention.  While being usable for the introduction of plates of any type of plates for conventional processing machines of all kinds (for example flexo printing, cutting), a device according to the invention is particularly suitable for the introduction of corrugated or micro-fluted cardboard plates for a digital printing machine according to the method according to the invention.
4. Résumé de l'invention 4. Summary of the invention
Tout ou partie de ces objectifs, ainsi que d'autres qui apparaîtront plus clairement par la suite sont atteints par l'invention à l'aide d'un procédé d'introduction d'éléments en plaque de carton ondulé ou à micro-cannelure, dans une machine de transformation, comprenant une étape de dépose d'un paquet d'éléments en plaque sur un ascenseur, une étape de montée progressive de l'ascenseur portant le paquet, une étape de saisie au cours de laquelle un effet vacuum est appliqué sur la surface supérieure de l'élément en plaque au sommet du paquet et une étape de transport au cours de laquelle l'élément en plaque saisi est transporté vers la machine de transformation.  All or part of these objectives, as well as others which will appear more clearly later are achieved by the invention using a method of introduction of corrugated board elements or micro-flute, in a processing machine, comprising a step of depositing a pack of plate elements on an elevator, a step of gradual rise of the elevator carrying the package, a capture step during which a vacuum effect is applied on the upper surface of the plate member at the top of the package and a transport step in which the grasped plate member is transported to the converting machine.
Ainsi les éléments en plaque de carton ondulé ou à micro-cannelure sont introduits sans en détériorer le bord frontal ou la surface.  Thus the elements of corrugated board or micro-flute are introduced without damaging the front edge or the surface.
Préférentiellement, au moins la partie frontale de l'élément en plaque saisi est soulevée lors de l'étape de saisie.  Preferably, at least the front portion of the gripped plate member is lifted during the gripping step.
On limite ainsi le risque de transporter une seconde plaque par adhérence avec la plaque saisie.  This limits the risk of transporting a second plate by adhesion with the plate entered.
Avantageusement lors de l'étape de saisie l'effet vacuum est appliqué sur au moins deux zones distinctes de la surface supérieure de l'élément en plaque au sommet du paquet, et le déplacement est contrôlé séparément pour chaque zone d'application de l'effet vacuum lors de l'étape de transport. Ce mode de réalisation permet de corriger lors de la phase de transport d'éventuelles erreurs de positionnement de l'élément en plaque. Advantageously, during the capture step, the vacuum effect is applied to at least two distinct zones of the upper surface of the plate element at the top of the packet, and the displacement is controlled separately for each zone of application of the vacuum effect during the transport step. This embodiment makes it possible to correct during the transport phase any positioning errors of the plate element.
Selon un mode de réalisation particulier, le procédé comprend une phase non-stop comprenant  According to a particular embodiment, the method comprises a non-stop phase comprising
- Une étape de dépose du paquet résiduel sur un dispositif non-stop ;  A step of depositing the residual packet on a non-stop device;
Une étape de descente de l'ascenseur ;  A step down the elevator;
Une étape de dépose d'un second paquet sur l'ascenseur ;  A step of depositing a second package on the elevator;
Une étape de montée progressive de l'ascenseur portant le second paquet ;  A step of gradually raising the elevator carrying the second package;
Une étape de fusion de paquets au cours de laquelle le paquet résiduel est déposé au sommet du second paquet ;  A packet merge step in which the residual packet is deposited at the top of the second packet;
Une étape de montée progressive de l'ascenseur portant le paquet fusionné. Ainsi le procédé permet d'introduire des plaques dans la machine de traitement sans nécessiter d'interruption pour ajouter de nouveaux paquets de plaques.  A step of gradual rise of the elevator carrying the fused package. Thus, the method makes it possible to introduce plates into the processing machine without requiring interruption to add new packets of plates.
Optionnellement le procédé comprend, en plus de l'étape non-stop, une étape de dépilage au cours de laquelle est formé le second paquet à partir d'une pile d'éléments en plaque.  Optionally, the method comprises, in addition to the non-stop step, an unstacking step during which the second packet is formed from a stack of plate elements.
Ainsi le procédé permet l'introduction en continu des plaques sans en détériorer le bord frontal ou la surface, à partir de piles de grande dimension dont on peut éliminer les dernières plaques abîmées par le transport.  Thus the method allows the continuous introduction of the plates without deteriorating the front edge or the surface, from large stacks which can be removed the last plates damaged by transport.
L'invention concerne également un dispositif d'introduction d'éléments en plaque pour une machine de transformation de plaques de carton ondulé, comprenant un ascenseur destiné à recevoir un paquet d'éléments en plaque, un dispositif de transport vacuum destiné à saisir l'élément en plaque situé au sommet du paquet par application de l'effet vacuum et à le transporter vers la machine de transformation et un contrôleur permettant de contrôler les mouvements de l'ascenseur et de commander le dispositif de transport vacuum. Ainsi le dispositif permet la mise en œuvre du procédé d'introduction selon l'invention et d'introduire les éléments en plaque sans en détériorer le bord frontal ou la surface.  The invention also relates to a plate element introduction device for a corrugated board plate converting machine, comprising an elevator for receiving a pack of plate elements, a vacuum transport device for gripping the plate. plate element located at the top of the package by applying the vacuum effect and transporting it to the processing machine and a controller for controlling the movements of the elevator and controlling the vacuum transport device. Thus the device allows the implementation of the method of introduction according to the invention and to introduce the plate elements without damaging the front edge or the surface.
Avantageusement le dispositif de transport vacuum est apte à soulever au moins la partie frontale de la plaque au sommet d'un paquet et est apte à faire avancer la plaque de manière contrôlée, afin de limiter le risque de transporter une seconde plaque adhérant à la plaque saisie.  Advantageously, the vacuum transport device is capable of lifting at least the front part of the plate at the top of a package and is able to advance the plate in a controlled manner, in order to limit the risk of transporting a second plate adhering to the plate. capture.
Optionnellement le transport vacuum comprend un caisson vacuum et une courroie présentant des ouvertures aux travers desquelles ledit caisson vacuum est apte à appliquer un effet vacuum sur la surface supérieure de la plaque au sommet d'un paquet pour la saisir. Préférentiellement, le dispositif d'introduction comprend au moins deux transports vacuum comprenant chacun un caisson vacuum et une courroie présentant des ouvertures aux travers desquelles ledit caisson vacuum est apte à appliquer un effet vacuum sur une zone de la surface supérieure de la plaque. Ainsi la saisie de la plaque est facilitée lorsque la laize est importante. Avantageusement, le contrôleur contrôle séparément les déplacements de chaque courroie des transports vacuum et permet de corriger lors du transport d'éventuelles erreurs de positionnement de la plaque saisie. Optionally the vacuum transport includes a vacuum chamber and a belt having openings through which said vacuum chamber is adapted to apply a vacuum effect on the upper surface of the plate at the top of a package to enter it. Preferably, the introduction device comprises at least two vacuum transports each comprising a vacuum chamber and a belt having openings through which said vacuum chamber is able to apply a vacuum effect on an area of the upper surface of the plate. Thus the input of the plate is facilitated when the width is important. Advantageously, the controller separately controls the movements of each belt of the vacuum transports and makes it possible to correct during the transport of any positioning errors of the plate seized.
Optionnellement, le dispositif d'introduction comprend un dispositif non-stop apte à recevoir le paquet résiduel d'éléments en plaque jusqu'à sa fusion avec un nouveau paquet d'éléments en plaque. Avantageusement, un tel dispositif d'introduction avec un dispositif non- stop comprend également une table de dépose apte à recevoir un paquet d'éléments en plaque destiné à être fusionné avec le paquet résiduel d'éléments en plaque.  Optionally, the introduction device comprises a non-stop device capable of receiving the residual pack of plate elements until it mergers with a new pack of plate elements. Advantageously, such an introduction device with a non-stop device also comprises a removal table adapted to receive a pack of plate elements to be merged with the residual pack of plate elements.
Ainsi le dispositif d'introduction permet d'introduire des plaques dans la machine de traitement sans interruption lorsqu'un nouveau paquet de plaques est fourni.  Thus, the introduction device makes it possible to introduce plates into the processing machine without interruption when a new pack of plates is provided.
Avantageusement le dispositif d'introduction avec un dispositif non-stop et une table de dépose comprend également un dispositif de dépilage apte à former des paquets à partir d'une pile d'éléments en plaque et à les déposer sur la table de dépose ; le dispositif de dépilage comprenant avantageusement un dispositif séparateur de paquet et une pince apte à saisir un paquet séparé par ledit dispositif séparateur et à déposer le paquet sur la table de dépose.  Advantageously, the introduction device with a non-stop device and a removal table also comprises an unstacking device able to form packets from a stack of plate elements and to deposit them on the deposit table; the unstacking device advantageously comprising a packet separator device and a clamp adapted to grip a package separated by said separator device and to deposit the package on the deposit table.
Ainsi le dispositif permet d'introduire des plaques dans la machine de traitement de façon continue et sans en détériorer le bord frontal ou la surface, à partir de piles de grande dimension dont on peut rejeter les plaques de la base qui ont été détériorées pendant le transport de la pile.  Thus the device makes it possible to introduce plates into the processing machine in a continuous manner and without deteriorating the front edge or the surface, from large stacks which can be rejected from the base plates which have been damaged during the treatment. transport of the battery.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante d'un mode de réalisation particulier, donné à titre de simple exemple illustratif et non limitatif, et des dessins annexés, parmi lesquels :  Other features and advantages of the invention will appear more clearly on reading the following description of a particular embodiment, given as a simple illustrative and nonlimiting example, and the appended drawings, among which:

6. Mode de réalisation  6. embodiment
Fig. 1 illustre de façon schématique un procédé et un dispositif d'introduction d'éléments en plaque de carton ondulé ou de micro-cannelure selon l'art antérieur. Classiquement, un feeder 10 comprend une jauge 11 permettant à un dispositif de transport 12 de séparer l'élément en plaque 13 se trouvant en bas du paquet 14, et de transporter l'élément en plaque 13 vers une machine non représentée. Ainsi qu'il est représenté Fig. 1, une nappe 15 d'éléments en plaque alimente fréquemment le feeder 10, de façon à ce que le niveau du paquet 14 reste sensiblement constant. Cette nappe 15 est créée par un pré-feeder 20 comportant une jauge 21, un dispositif de transport 22. Un dispositif pousseur 23 permet de scinder une pile 24 d'éléments en plaque en une succession de paquets 25 alimentant le pré-feeder.  Fig. 1 schematically illustrates a method and a device for introducing elements of corrugated board or micro-groove according to the prior art. Conventionally, a feeder 10 comprises a gauge 11 allowing a transport device 12 to separate the plate member 13 at the bottom of the packet 14, and to transport the plate member 13 to a machine not shown. As shown in FIG. 1, a web 15 of plate elements frequently feed the feeder 10, so that the level of the package 14 remains substantially constant. This sheet 15 is created by a pre-feeder 20 comprising a gauge 21, a transport device 22. A pusher device 23 makes it possible to split a stack 24 of plate elements into a succession of packets 25 feeding the pre-feeder.
Les jauges 11 et 21 sont difficiles à régler, en particulier pour des épaisseurs de plaques inférieures à 1,5 millimètre, et sont responsables de nombreux bourrages. De plus ces jauges détériorent fréquemment le bord frontal des éléments en plaques, ce qui est problématique pour l'introduction d'éléments en plaque dans une machine d'impression numérique. Le dispositif pousseur 23 peut également marquer le bord arrière des éléments en plaque, voire pousser le paquet de travers.  The gauges 11 and 21 are difficult to adjust, in particular for plate thicknesses less than 1.5 millimeters, and are responsible for many jams. In addition these gauges frequently deteriorate the front edge of the plate elements, which is problematic for the introduction of plate elements in a digital printing machine. The pusher device 23 may also mark the trailing edge of the plate elements, or even push the package across.
Fig. 2 à Fig. 9 représentent un dispositif d'introduction 30 conforme à l'invention, comprenant un ascenseur 31 sur lequel est placé un paquet 32 d'éléments en plaque, par exemple de carton ondulé ou de micro-cannelure. Un contrôleur 33 contrôle le mouvement de l'ascenseur Fig. 2 to FIG. 9 show an introducer 30 according to the invention, comprising an elevator 31 on which is placed a pack 32 of plate elements, for example corrugated cardboard or micro-groove. A controller 33 controls the movement of the elevator
31 de façon classique pour que le sommet du paquet 32 reste à un niveau sensiblement constant. Un dispositif de transport vacuum 34 soulève au moins la partie frontale de l'élément en plaque 35 situé au sommet du paquet 32 par application d'un effet vacuum sur la surface de la plaque, et transporte la plaque 35 de façon contrôlée vers la machine de transformation non représentée. Fig. 3 représente l'élément en plaque 35 en fin de phase de transport. 31 so that the top of the package 32 remains at a substantially constant level. A vacuum transport device 34 raises at least the front portion of the plate member 35 located at the top of the pack 32 by applying a vacuum effect to the surface of the plate, and transports the plate 35 in a controlled manner to the machine. transformation not shown. Fig. 3 shows the plate member 35 at the end of the transport phase.
Dans un procédé d'introduction d'éléments en plaque conforme à l'invention, un paquet In a method of introducing plate elements according to the invention, a package
32 est déposé sur un ascenseur 31 dont l'ascension est contrôlée ; lors d'une phase de saisie un effet vacuum est appliqué sur la face supérieure de l'élément en plaque 35 situé au sommet du paquet 32, et l'élément en plaque 35 saisi est transporté lors d'une phase de transport. Préférentiellement, la partie frontale de l'élément en plaque 35 est soulevée lors de la phase de saisie, et le déplacement est contrôlé lors de la phase de transport. Ainsi dans un procédé d'introduction conforme à l'invention, les éléments en plaque de carton ondulé ou à micro-cannelure sont introduits dans la machine de traitement après avoir été regroupés en paquets, chaque plaque étant séparée du sommet du paquet et introduite sans passer par des jauges ni subir de frottement sur sa surface supérieure. 32 is deposited on an elevator 31 whose ascension is controlled; during a capture phase a vacuum effect is applied to the upper face of the plate member 35 located at the top of the packet 32, and the plate member 35 is conveyed during a transport phase. Preferably, the front portion of the plate member 35 is lifted during the gripping phase, and the movement is controlled during the transport phase. Thus, in an introduction method according to the invention, the corrugated or micro-corrugated board elements are introduced into the processing machine after having been grouped into packets, each plate being separated from the top of the pack and introduced without pass through gauges or rub on its upper surface.
L'étape préliminaire de mise en paquet à partir d'une pile peut être réalisée de nombreuses façons différentes. C'est une étape additionnelle par rapport au fonctionnement classique des margeurs selon l'art antérieur qui utilisent directement les piles placées sur des palettes. L'utilisation de paquets dans le procédé d'introduction permet de s'affranchir des palettes, elle permet également d'écarter les dernières plaques des piles qui sont très fréquemment endommagées, et enfin elle permet de réduire la hauteur du dispositif. En effet les piles d'éléments en plaque sont de grandes dimensions et leur utilisation directe impose soit de surélever la machine soit d'abaisser l'alimentation des piles  The preliminary step of packing from a stack can be done in many different ways. This is an additional step compared to the conventional operation of the feeders according to the prior art which directly use the batteries placed on pallets. The use of packets in the introduction process makes it possible to dispense with the pallets, it also makes it possible to discard the last plates of the batteries which are very frequently damaged, and finally it makes it possible to reduce the height of the device. Indeed, the stacks of plate elements are large and their direct use requires either raising the machine or lowering the battery power
Le dispositif de transport vacuum 34 peut prendre de nombreuses formes. Le mode de mise en œuvre représenté comprend avantageusement deux dispositifs de transport vacuum 34, placés sur un élément support 36 et dont l'écartement peut être réglé de façon à s'adapter à la laize des éléments en plaque. Optionnellement, chaque transport vacuum 34 peut être contrôlé individuellement lors de la phase de transport, ce qui permet de corriger une éventuelle erreur de positionnement de la plaque 35 au sommet du paquet 32.  The vacuum transport device 34 can take many forms. The illustrated embodiment advantageously comprises two vacuum transport devices 34, placed on a support member 36 and whose spacing can be adjusted to fit the width of the plate elements. Optionally, each vacuum transport 34 can be individually controlled during the transport phase, which makes it possible to correct any positioning error of the plate 35 at the top of the package 32.
Avantageusement, le dispositif de transport vacuum 34 comprend un caisson vacuum 37 et une courroie 38 munie d'ouvertures au travers desquelles le caisson vacuum 37 peut appliquer l'effet vacuum à la surface des plaques 34 saisies et transportées. La mise en mouvement de la courroie 38 permet de transporter la plaque 34 une fois qu'elle a été saisie par application de l'effet vacuum. Fig. 5 représente un mode de réalisation particulier où l'élément support 36 est creux de façon à protéger en les contenant les dispositifs permettant de transmettre l'effet vacuum jusqu'au sein des caissons 37 des deux dispositifs de transport vacuum 34. Ainsi dans l'exemple de mise en œuvre de l'invention représenté Fig. 5, deux tuyaux 39 émergent du dispositif support 36 et sont reliés à des ouvertures prévues dans le flanc des caissons vacuum 37 des dispositifs de transport vacuum 34.  Advantageously, the vacuum transport device 34 comprises a vacuum box 37 and a belt 38 provided with openings through which the vacuum box 37 can apply the vacuum effect to the surface of the plates 34 captured and transported. The setting in motion of the belt 38 makes it possible to transport the plate 34 once it has been grasped by application of the vacuum effect. Fig. 5 represents a particular embodiment where the support member 36 is hollow so as to protect containing the devices for transmitting the vacuum effect into the caissons 37 of the two vacuum transport devices 34. Thus in the example of implementation of the invention shown in FIG. 5, two pipes 39 emerge from the support device 36 and are connected to openings provided in the side of the vacuum boxes 37 of the vacuum transport devices 34.
Fig. 4 représente le moment où arrive sous le dispositif de transport vacuum 34 l'extrémité arrière de la plaque 35 introduite dans la machine de traitement. Avantageusement, le dispositif d'introduction 30 empêche la plaque suivante 40 d'être saisie immédiatement, afin de limiter le risque de bourrage en aval dans la machine de traitement. Différents modes de réalisation de cette fonction sont envisageables, selon le type de substrat travaillé et selon la machine alimentée. Fig. 4 represents the moment when arrives under the vacuum transport device 34 the rear end of the plate 35 introduced into the processing machine. Advantageously, the introduction device 30 prevents the next plate 40 from being seized immediately, in order to limit the risk of downstream stuffing in the processing machine. Different embodiments of this function are possible, depending on the type of substrate worked and the machine powered.
Ainsi, lorsque la machine de transformation alimentée tient fermement la plaque 35 dès sa sortie du dispositif d'introduction 30 et lorsque les plaques sont suffisamment rigides, il suffit que le dispositif de transport vacuum 34 stoppe le mouvement de la courroie 38 avant qu'une partie du caisson vacuum 37 ne soit découverte par la partie arrière de la plaque 35 introduite. La plaque introduite 35 est alors transportée par la machine de traitement, sa partie arrière glissant sur la bande du transport vacuum 38. L'effet vacuum s'applique à la plaque suivante 40 au fur et à mesure que la plaque 35 introduite découvre le caisson vacuum 37, sans que la plaque suivante 40 ne soit transportée puisque la courroie 38 du dispositif de transport vacuum 34 n'est pas en mouvement.  Thus, when the powered transformation machine firmly holds the plate 35 as soon as it leaves the insertion device 30 and when the plates are sufficiently rigid, it is sufficient for the vacuum transport device 34 to stop the movement of the belt 38 before a part of the vacuum chamber 37 is found by the rear portion of the plate 35 introduced. The inserted plate 35 is then transported by the processing machine, its sliding rear part on the belt of the vacuum transport 38. The vacuum effect applies to the next plate 40 as the plate 35 introduced discovers the box vacuum 37, without the following plate 40 being transported since the belt 38 of the vacuum transport device 34 is not moving.
Dans le cas où les plaques sont plus fragiles, en particulier si le dispositif de transport vacuum 34 est équipé d'une courroie 38 avec un très fort coefficient de frottement, on peut couper l'effet vacuum pour limiter le frottement, voire utiliser un dispositif de séparation 41 qui éloigne la fin de la plaque 35 de la courroie 38, par exemple au moyen d'un patin mobile présentant avantageusement un très faible coefficient de frottement.  In the case where the plates are more fragile, particularly if the vacuum transport device 34 is equipped with a belt 38 with a very high coefficient of friction, the vacuum effect can be cut to limit the friction, or even use a device separation piece 41 which moves the end of the plate 35 away from the belt 38, for example by means of a movable pad advantageously having a very low coefficient of friction.
Le dispositif d'introduction représenté Fig. 2 à Fig. 9 est équipé d'un dispositif optionnel de taquage arrière 42 et d'un dispositif optionnel d'appui 43. Le dispositif de taquage arrière 42 permet de positionner correctement les plaques situées en haut du paquet 32 contre le dispositif d'appui 43. Le dispositif d'appui 43 prend ici la forme d'une plaque.  The introducer shown in FIG. 2 to FIG. 9 is equipped with an optional rear jogging device 42 and an optional support device 43. The rear jogging device 42 makes it possible to correctly position the plates situated at the top of the pack 32 against the support device 43. support device 43 here takes the form of a plate.
Au fur et à mesure que les plaques sont introduites par le dispositif d'introduction 30, l'ascenseur 31 monte le paquet 32. La montée de l'ascenseur 31 est contrôlée par un contrôleur 33 représenté schématiquement Fig. 5, mais dont la position au sein du dispositif d'introduction 30 n'est pas importante. La distance à monter à chaque plaque peut être calculée si l'épaisseur des plaques est suffisamment constante, ou bien déduite par le contrôleur 33 au moyen de mesures de ou de détections effectuées par des capteurs, par exemple placés dans le dispositif de taquage arrière 42. Le contrôleur 33, typiquement de type microprocesseur ou microcontrôleur, permet également de commander le dispositif de transport vacuum 34.  As the plates are introduced by the introduction device 30, the elevator 31 mounts the package 32. The rise of the elevator 31 is controlled by a controller 33 shown schematically in FIG. 5, but whose position within the introduction device 30 is not important. The distance to be mounted to each plate can be calculated if the thickness of the plates is sufficiently constant, or deduced by the controller 33 by means of measurements or detections made by sensors, for example placed in the rear jogging device. The controller 33, typically of the microprocessor or microcontroller type, also makes it possible to control the vacuum transport device 34.
Les dispositifs d'introduction 30 selon l'invention décrits jusqu'à présent sont parfaitement adaptés à l'utilisation d'un dispositif non-stop, et les figures Fig. 2 à Fig. 9 représentent un exemple de dispositif d'introduction 30 selon l'invention équipé d'un dispositif non-stop 45 particulièrement avantageux. Le dispositif non-stop 46 comprend une grille 46 qui se trouve à l'extérieur du dispositif d'introduction 30 lorsque le dispositif non stop 45 n'est pas en action. The introduction devices 30 according to the invention described up to now are perfectly adapted to the use of a non-stop device, and FIGS. 2 to FIG. 9 show an example of introduction device 30 according to the invention equipped with a particularly advantageous non-stop device 45. The non-stop device 46 comprises a gate 46 which is outside the insertion device 30 when the non-stop device 45 is not in action.
Comme représenté Fig. 6, la grille 46 du dispositif non-stop 45 est insérée dans le dispositif d'introduction 30 lorsque l'ascenseur 31 arrive à une certaine hauteur. Dans l'exemple représenté, l'ascenseur 31 est constitué de rouleaux, la grille 46 du dispositif non-stop 45 venant s'intercaler entre les rouleaux. Comme à ce stade le dispositif non-stop 45 n'a rien à porter, la flexion de la grille As shown in FIG. 6, the gate 46 of the non-stop device 45 is inserted into the insertion device 30 when the elevator 31 reaches a certain height. In the example shown, the elevator 31 consists of rollers, the grid 46 of the non-stop device 45 being interposed between the rollers. As at this stage the non-stop device 45 has nothing to wear, the bending of the grid
46 n'est pas grande bien qu'elle soit en porte-à-faux lors de son insertion. 46 is not large although it is cantilevered when inserted.
En revanche, comme représenté Fig. 7 et Fig. 8, la grille 46 du dispositif non-stop 45 prend appui sur ses deux extrémités lorsque l'ascenseur 31 redescend, de façon à supporter le poids du paquet 32 résiduel sans fléchir.  On the other hand, as shown in FIG. 7 and FIG. 8, the grid 46 of the non-stop device 45 bears on its two ends when the elevator 31 descends, so as to support the weight of the remaining pack 32 without bending.
La montée de la grille 46 du dispositif non-stop 45 est commandée par le contrôleur 33, afin que le dispositif d'introduction 30 continue d'alimenter la machine avec les plaques du paquet 32 résiduel, ce qui permet de placer un nouveau paquet 47 sur l'ascenseur 31. Une fois le paquet The rise of the gate 46 of the non-stop device 45 is controlled by the controller 33, so that the insertion device 30 continues to supply the machine with the plates of the remaining pack 32, which enables a new pack 47 to be placed. on the elevator 31. Once the package
47 placé, l'ascenseur 31 est remonté jusqu'à ce que le nouveau paquet 47 soit presque en contact avec la grille 46 qui est alors retirée, de telle sorte que le paquet résiduel 32 fusionne avec le nouveau paquet 47. 47, the elevator 31 is raised until the new package 47 is almost in contact with the grid 46 which is then removed, so that the residual package 32 merges with the new package 47.
Avantageusement le cadre servant à monter et descendre le dispositif 45 peut aussi embarquer un ou plusieurs dispositifs de soutien servant à retenir le bord frontal des dernières plaques qui composent le paquet résiduel 32 lorsque la grille 46 du dispositif non-stop 45 est retirée. Ces dispositifs de soutien peuvent être passifs, comme des crochets flexibles ou des brosses ou encore être un ou plusieurs dispositifs actifs commandés par l'unité de contrôle 33. On limite ainsi le risque d'interruption d'alimentation en plaque lié à la fusion du paquet résiduel 32 avec le nouveau paquet 47.  Advantageously, the frame for raising and lowering the device 45 can also carry one or more support devices for retaining the front edge of the last plates that make up the residual package 32 when the grid 46 of the non-stop device 45 is removed. These support devices may be passive, such as flexible hooks or brushes or be one or more active devices controlled by the control unit 33. This limits the risk of interruption of the plate supply related to the melting of the residual package 32 with the new package 47.
Dans l'exemple de mise en œuvre de l'invention, les rouleaux de l'ascenseur 31 sont entraînés par friction. L'ascenseur 31 peut ainsi déplacer le paquet 47 jusqu'au dispositif d'appui 43 sans qu'il soit nécessaire de motoriser les rouleaux de l'ascenseur 31. Alternativement les rouleaux de l'ascenseur peuvent être motorisés.  In the exemplary implementation of the invention, the rollers of the elevator 31 are driven by friction. The elevator 31 can thus move the package 47 to the support device 43 without the need to motorize the rollers of the elevator 31. Alternatively the rollers of the elevator can be motorized.
Avantageusement, le dispositif d'introduction 30 équipé du dispositif non-stop 45 comprend également une table de dépose 48 permettant de placer facilement les nouveaux paquets 47 sur l'ascenseur 31. Une telle plaque d'introduction 48 peut optionnellement être équipée de dispositif de contrôle, par exemple de lecture de marques, afin de vérifier que le paquet 47 est valide et correctement orienté. Le dispositif d'introduction 30 équipé d'un dispositif non-stop 45 peut être alimenté en paquets de nombreuses façons différentes, par exemple manuellement ou bien par un robot. Les figures Fig. 9 à Fig. 12 représentent schématiquement un dispositif de dépilage 50 particulièrement avantageux, permettant de former des paquets à partir d'une pile 51, et de placer ces paquets sur la table de dépose 48. Advantageously, the introduction device 30 equipped with the non-stop device 45 also comprises a removal table 48 making it easy to place the new packs 47 on the elevator 31. Such an introduction plate 48 may optionally be equipped with control, for example reading marks, to verify that the packet 47 is valid and correctly oriented. The introduction device 30 equipped with a non-stop device 45 can be fed in packets in many different ways, for example manually or by a robot. The figures 9 to FIG. 12 schematically show a particularly advantageous unstacking device 50, making it possible to form packets from a stack 51, and to place these packets on the deposit table 48.
Dans un premier temps, on introduit une pile 51 d'éléments en plaque avec un convoyeur non représenté sur une table 52. La pile fait typiquement 2m de haut mais rien n'empêche d'utiliser des piles d'autres hauteurs.  Firstly, a stack 51 of plate elements is introduced with a conveyor not shown on a table 52. The stack is typically 2m high, but nothing prevents the use of piles of other heights.
L'exemple de dispositif de dépilage 50 représenté Fig. 9 à Fig. 12 comprend une pince 53 comprenant deux dispositifs de taquage latéraux motorisés 54, un dispositif de taquage arrière motorisé 55, un dispositif de taquage frontal fixe 56, une fourche motorisée 57 et un dispositif de séparation de pile 58.  The example of unstacking device 50 shown in FIG. 9 to FIG. 12 comprises a clamp 53 comprising two motorized lateral jogging devices 54, a motorized rear jogging device 55, a fixed front jogging device 56, a motorized fork 57 and a battery separating device 58.
Lors de la dépose sur la table 52 de la pile 51, la hauteur de cette dernière est mesurée par un capteur (non représenté). Le dispositif de commande décide alors combien de paquets de tailles sensiblement similaires seront constitués. Les dernières plaques du bas de la pile 51 seront sur option évacuées car considérées comme endommagées par le transport.  Upon removal from the table 52 of the stack 51, the height of the latter is measured by a sensor (not shown). The controller then decides how many packages of substantially similar sizes will be made. The last plates of the bottom of the pile 51 will be optionally evacuated as considered damaged by the transport.
La pince 53 est abaissée jusqu'à l'endroit où on désire créer le premier paquet. Les taquages latéraux 54 et arrière 55 se resserrent, puis le dispositif de séparation de paquet 58 sépare le futur paquet sur le haut de la pile 51. Par exemple le dispositif de séparation 58 représenté comprend un piston qui vient pousser un plan incliné lequel vient soulever le bord avant d'un élément en plaque de la pile. La fourche 57 peut alors s'introduire sous le paquet ainsi constitué. Ce système avec un seul dispositif de séparation centré est particulièrement adapté, car il s'adapte aux différentes piles d'éléments en plaque qui ne sont pas toujours planes , les éléments en plaque pouvant présenter un tuilage. Dans l'exemple de mise en œuvre de l'invention le dispositif de séparation de paquet 58 est un sous-ensemble de la pince 53, mais ce dispositif de séparation peut éventuellement être distinct de la pince 53.  The clamp 53 is lowered to where you want to create the first package. The lateral 54 and rear 55 tilts are tightened, then the package separation device 58 separates the future package on the top of the stack 51. For example, the separation device 58 shown comprises a piston which pushes an inclined plane which raises the front edge of a plate element of the stack. The fork 57 can then be introduced under the package thus formed. This system with a single centered separation device is particularly suitable because it adapts to different stacks of plate elements that are not always flat, the plate elements may have a tiling. In the exemplary embodiment of the invention, the package separation device 58 is a subset of the clamp 53, but this separation device may possibly be distinct from the clamp 53.
Le paquet est alors transporté au-dessus de la table de dépose 48, puis relâché par la pince 53 sur la table de dépose 48, qui va alors transporter le paquet jusque sur l'ascenseur 31 lorsque celui-ci sera redescendu pendant que le dispositif non-stop 45 supportera le paquet résiduel 32.  The package is then transported over the depositing table 48, then released by the clamp 53 onto the deposit table 48, which will then transport the package to the elevator 31 when the latter is lowered while the device non-stop 45 will support the residual packet 32.
