Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne une installation destinée à permettre la réalisation automatique, c'est-à-dire en l'absence de toute intervention d'un opérateur ou d'un utilisateur, d'un album, notamment photographique, constitué d'une pluralité de feuillets solidarisés entre eux et articulés entre eux au niveau de l'une de leur tranche, de telle sorte à constituer une reliure.The invention relates to an installation intended to allow the automatic realization, that is to say in the absence of any intervention of an operator or a user, of an album, in particular a photographic album, consisting of a plurality sheets joined together and articulated together at one of their edges, so as to constitute a binding.

L'objectif premier visé par la présente invention consiste à permettre à un utilisateur d'imprimer, par le biais d'une imprimante thermique, les différents clichés réalisés par photographie numérique et à immédiatement réaliser un album photographique correspondant.The primary objective of the present invention is to enable a user to print, by means of a thermal printer, the different shots made by digital photography and immediately make a corresponding photographic album.

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE TECHNIQUE

A ce jour, et de manière la plus courante, lorsqu'un utilisateur souhaite compiler des photographies, qu'elles soient d'ailleurs d'origine argentique ou numérique, en fonction de thèmes ou d'évènements déterminés, il dispose de la faculté de coller ou d'insérer les photos en question au sein d'un album classique constitué d'une pluralité de feuillets rigides assemblés entre eux au niveau d'une charnière. Chaque feuillet est associé à un rabat transparent réalisé en un film plastique permettant de positionner les photos au gré de l'utilisateur. Ce type d'album est lourd et encombrant, et ne permet donc pas de disposer d'autant d'albums que de thèmes de photos en question.To date, and most commonly, when a user wishes to compile photographs, whether they are of silver or digital origin, according to specific themes or events, he has the faculty of paste or insert the photos in question in a classic album consisting of a plurality of rigid sheets assembled together at a hinge. Each sheet is associated with a transparent flap made of a plastic film to position the photos at the discretion of the user. This type of album is heavy and cumbersome, and therefore does not allow to have as many albums as photo themes in question.

Or, avec l'explosion littérale des photos numériques, les utilisateurs sont de plus en plus demandeurs d'albums thématiques, adaptés aux dimensions, notamment en termes d'épaisseur, c'est-à-dire fonction du nombre de tirages.However, with the literal explosion of digital photos, users are increasingly demanding thematic albums, adapted to the dimensions, especially in terms of thickness, that is to say function of the number of prints.

On a décrit dans le document FR 2 904 579 un dispositif semi-automatique permettant d'ores et déjà de faciliter la réalisation d'un tel album. Fondamentalement, ce dispositif comprend :

  • une unité de pliage des feuillets aux fins de les configurer au format souhaité ;
  • une unité de rainage desdits feuillets, de telle sorte à faciliter leur pliage et à maintenir lesdits feuillets sous leur forme pliée ;
  • une unité d'encollage, destinée à encoller deux à deux partie au moins des feuillets après pliage ;
  • et un plateau de réception des feuillets rainés et de compilation desdits feuillets entres eux aux fins de réaliser un album, ledit plateau de réception étant mobile en translation parallèlement à la direction de progression desdits feuillets au sein du dispositif, et ce entre plusieurs positions et en synchronisme avec le fonctionnement de l'unité de pliage.
We have described in the document FR 2 904 579 a semi-automatic device already allowing to facilitate the realization of such an album. Basically, this device includes:
  • a folding unit of the leaflets to configure them in the desired format;
  • a creasing unit of said leaflets, so as to facilitate their folding and to maintain said leaflets in their folded form;
  • a sizing unit, intended to glue two or two parts at least of the sheets after folding;
  • and a receiving tray of the slotted leaflets and compiling said leaflets therebetween for the purpose of producing an album, said receiving tray being movable in translation parallel to the direction of progression of said leaflets within the device, and this between several positions and synchronism with the operation of the folding unit.

Si incontestablement, ce dispositif constitue un progrès significatif pour la réalisation d'album photo et notamment de photos numériques, en revanche il se heurte aux inconvénients suivants.So unquestionably, this device is a significant advance for the production of photo album including digital photos, however it faces the following drawbacks.

Tout d'abord, l'album après réalisation doit être récupéré par un opérateur sur le plateau et ensuite soumis à l'action d'un massicot aux fins de propreté, les différents feuillets subissant de légers décalages en termes de positionnement lors de leur compilation. Ceci empêche la production automatique en continu de plusieurs albums sans intervention d'un opérateurFirst, the album after completion must be recovered by an operator on the board and then subjected to the action of a cutter for cleanliness, the various sheets experiencing slight misalignment in terms of positioning during compilation . This prevents the automatic production of several albums continuously without the intervention of an operator

De plus, l'unité d'encollage mise en oeuvre, certes escamotable hors dudit dispositif ainsi décrit, s'avère relativement délicate à manipuler en raison de sa conception.In addition, the sizing unit implemented, certainly retractable out of said device thus described, is relatively difficult to handle because of its design.

Au surplus, ce dispositif est relativement encombrant et pesant, constituant un obstacle pour certains utilisateurs potentiels.In addition, this device is relatively bulky and heavy, constituting an obstacle for some potential users.

EP-A2-1 886 831 montre aussi l'état de la technique. EP-A2-1 886 831 also shows the state of the art.

L'objectif visé par la présente invention est de proposer une installation complètement automatique pour la réalisation d'un tel album, dans la mesure où tout d'abord, les tirages imprimés par exemple par une imprimante thermique, sont immédiatement pris en charge par l'installation proprement dite, sans intervention aucune d'un quelconque opérateur ou de l'utilisateur, et dans la mesure où, ladite installation comprend un massicot intégré et une unité d'éjection de l'album après réalisation et découpe.The aim of the present invention is to propose a completely automatic installation for the production of such an album, insofar as first of all, the prints printed for example by a thermal printer, are immediately taken care of by the printer. installation proper, without any intervention of any operator or the user, and in that, said installation comprises an integrated paper cutter and an ejection unit of the album after production and cutting.

said sheets being received and compiled at a receiving plate, provided for this purpose with reference members, said plate being able to move in translation in a direction substantially parallel to the direction of progression of the sheets within the installation between several positions and in synchronism with, in particular, the gluing unit.

Selon l'invention, l'unité de retournement du feuillet de couverture comporte un bras sensiblement curviligne, articulé sur le bâti de l'installation, destiné à se mouvoir entre au moins deux positions extrêmes, respectivement une position inférieure ou basse, propre à recevoir la partie amont du feuillet de couverture, et une position supérieure ou haute, destinée à induire notamment le rabat de la partie amont du feuillet de couverture sur les autres feuillets intermédiaires. Ce bras articulé est mû entre ces deux positions extrêmes au moyen d'une came motorisée, et est pourvu au niveau de son extrémité opposée à son axe d'articulation d'un rouleau monté fou en rotation, apte à coopérer avec partie des rouleaux assurant la progression des feuillets au sein de l'installation.According to the invention, the cover sheet reversal unit comprises a substantially curvilinear arm, articulated on the frame of the installation, intended to move between at least two extreme positions, respectively a lower or lower position, adapted to receive the upstream portion of the cover sheet, and an upper or upper position, intended to induce in particular the flap of the upstream portion of the cover sheet on the other intermediate sheets. This articulated arm is moved between these two extreme positions by means of a motorized cam, and is provided at its end opposite its axis of articulation of a roller mounted idler in rotation, adapted to cooperate with part of the rollers ensuring progress of leaflets within the facility.

Avantageusement, l'installation est pourvue d'un massicot intégré, destiné à assurer la découpe franche des bords libres des feuillets constitutifs de l'album après réalisation de celui-ci, ledit album étant acheminé au niveau de la zone opérationnelle dudit massicot par le plateau de réception. Ce faisant, on gagne en sécurité en raison de l'absence de toute manipulation dangereuse.Advantageously, the installation is provided with an integrated cutter, intended to ensure the free cutting of the free edges of the constituent sheets of the album after completion thereof, said album being conveyed at the operational zone of said cutter by the reception tray.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On a donc représenté en relation avec les figures 1 et 2 une vue générale de l'installation conforme à l'invention. Celle-ci présente une compacité élevée, dans la mesure où, au sein d'un même bâti 1 sont inclus d'une part une imprimante thermique 3, (par exemple du type format 8 pouces x 12 pouces commercialisée sous la dénomination SHINKO SHS-1245), destinée à imprimer des clichés obtenus par photographie numérique, lesdits clichés étant assemblés par un logiciel de composition d'album ou tout autre logiciel, ladite imprimante étant reliée à un PC (non représenté), et de manière sous-jacente par rapport à l'imprimante 3, une unité fonctionnelle 4, propre à assurer la réalisation proprement dite d'un album en l'espèce de photographies numériques.We therefore represented in relation with the Figures 1 and 2 a general view of the installation according to the invention. This has a high compactness, insofar as, within the same frame 1 are included firstly a thermal printer 3, (for example of the 8 inch x 12 inch format marketed under the name SHINKO SHS- 1245) for printing photographs obtained by digital photography, said images being assembled by an album composition software or any other software, said printer being connected to a PC (not shown), and in an underlying way to the printer 3, a functional unit 4, able to ensure the actual realization of an album in this case digital photographs.

On a illustré par la référence 7 la sortie des tirages issus de l'imprimante, lesdits tirages étant ensuite pris en charge par l'unité fonctionnelle 4, ainsi que décrit plus en détail ci-après. 7 is the output of the prints from the printer, said prints being then supported by the functional unit 4, as described in more detail below.

Selon une variante de l'invention (non représentée), l'imprimante thermique 3 est remplacée par un dépileur (mieux connu sous l'expression anglo-saxonne « stacker ») c'est-à-dire une pile de clichés préalablement réalisés, ou par tout autre type d'imprimante, notamment à jet d'encre.According to a variant of the invention (not shown), the thermal printer 3 is replaced by a unstacker (better known by the English expression " stacker "), that is to say a stack of previously made clichés, or by any other type of printer, especially ink jet.

On a ménagé sous l'unité fonctionnelle 4 un réceptacle 5 des albums réalisés par celle-ci, un accès 6 étant en outre prévu pour permettre à l'utilisateur de récupérer le ou les albums stockés dans ledit réceptacle 5. Under the functional unit 4 there is a receptacle 5 of the albums made by the latter, access 6 being further provided to allow the user to recover the album or albums stored in said receptacle 5.

Cet ensemble est accessible par une porte 2 articulée sur le bâti 1, permettant ainsi d'assurer la maintenance de l'installation et plus particulièrement, et avantageusement de changer simultanément le consommable de l'imprimante 3 et le consommable de l'unité d'encollage, telle que décrite plus en détail ultérieurement. On conçoit d'ores et déjà outre la compacité de l'installation, la facilité de maintenance d'une telle installation.This assembly is accessible through a door 2 hinged to the frame 1, thus ensuring the maintenance of the installation and more particularly, and advantageously simultaneously change the consumable of the printer 3 and the consumable of the unit. sizing, as described in more detail later. In addition to the compactness of the installation, the ease of maintenance of such an installation is already conceivable.

On a représenté plus en détail au sein des figures 3 et 4 l'unité fonctionnelle proprement dite 4. Tel qu'on peut bien l'observer notamment au sein de la figure 4, l'unité fonctionnelle 4 comporte un certain nombre de rouleaux assurant différentes fonctions, notamment de progression des feuillets issus de l'imprimante 3, mais également de contre réaction (notamment lors de la phase de collage) et de rouleaux presseurs pour assurer la cohésion et le maintien de l'album à proprement dit.Represented in more detail within figures 3 and 4 the functional unit itself 4. As can be seen in particular in the figure 4 , the functional unit 4 comprises a number of rollers providing different functions, including progress sheets from the printer 3, but also against reaction (especially during the bonding phase) and pressure rollers to ensure cohesion and maintaining the album itself.

Ainsi donc les rouleaux 11, 15, 17, 19, 26, et 30 sont tous motorisés, et actionnés par le biais d'une courroie crantée 39 mue en rotation par un moteur électrique 31.Thus the rollers 11, 15, 17, 19, 26, and 30 are all motorized, and actuated by means of a toothed belt 39 rotated by an electric motor 31 .

L'installation comporte également, ainsi que déjà dit, des rouleaux presseurs respectivement 28, 32 et 33, montés fous en rotation, et destinés à exercer une pression sur l'album en cours de constitution, ainsi que décrit plus en détail ultérieurement.The installation also comprises, as already said, pressure rollers respectively 28, 32 and 33 , mounted idle in rotation, and intended to exert pressure on the album being formed, as described in more detail later.

Les rouleaux 10, 14, 16, 20, 25, 29 représentés sur les figures 3 et 4 sont montés fous en rotation, ou simplement viennent engrener sur le rouleau sur lequel ils sont maintenus en pression. Le rouleau 27 sert de simple guide : il est monté fou. Les rouleaux spécifiques à l'unité d'encollage 22, 23 et 24, faisant l'objet également d'une description spécifique ultérieure.The rollers 10, 14, 16, 20, 25, 29 shown in the figures 3 and 4 are mounted crazy in rotation, or simply mesh with the roller on which they are held in pressure. The roller 27 serves as a simple guide: it is mounted crazy. The rolls specific to the sizing unit 22 , 23 and 24 , which are also the subject of a specific description later.

Ces différents rouleaux sont pourvus à leur périphérie soit d'une couche de mousse, soit d'une couche de silicone, selon que l'on souhaite qu'ils exercent une adhérence sur le feuillet non encollé ou au contraire s'oppose à toute forme d'adhérence au contact des feuillets encollés.These different rollers are provided at their periphery with either a layer of foam or a layer of silicone, depending on whether it is desired that they exert an adhesion on the unsized sheet or on the contrary opposes any shape adhesion in contact with glued sheets.

Aux fins de mieux comprendre le fonctionnement et la structure de cette unité fonctionnelle 4, il va être décrit ci-après les différentes étapes mises en oeuvre pour la réalisation d'un album conformément à l'invention.In order to better understand the operation and the structure of this functional unit 4 , the various steps implemented for the production of an album according to the invention will be described below.

Ainsi et en référence aux figures 10a à 10d, ont été illustrées les différentes étapes d'introduction de l'ensemble des feuillets constitutifs de l'album au sein de l'unité fonctionnelle et des premières phases de progression desdits feuillets au sein de l'unité fonctionnelle 4.So and with reference to Figures 10a to 10d , have been illustrated the various steps of introduction of all the sheets constituting the album within the functional unit and the first stages of progression of said sheets within the functional unit 4 .

Ainsi le feuillet 50 issu de l'imprimante 3 est guidé par des déflecteurs appropriés (non représentés), au niveau de deux rouleaux d'entrée 10 et 11 de l'unité fonctionnelle. L'introduction du feuillet 50 à ce niveau est en outre détectée par un détecteur 12, en l'espèce constitué d'une cellule photoélectrique, induisant l'activation du moteur 31, et corollairement la rotation des rouleaux appartenant à ce premier groupe moteur.Thus the sheet 50 from the printer 3 is guided by appropriate baffles (not shown), at two input rollers 10 and 11 of the functional unit. The introduction of the sheet 50 at this level is further detected by a detector 12 , in this case constituted by a photoelectric cell, inducing the activation of the motor 31 , and corollary the rotation of the rollers belonging to this first motor unit.

Le feuillet ainsi détecté est donc pris en charge par le couple de rouleaux 10 et 11, qui induit sa descente en zone postérieure de l'unité fonctionnelle 4. Lorsque le feuillet a été intégralement pris en charge par le couple de rouleaux 10 et 11, la cellule de détection 12 induit l'inversement du sens de rotation du moteur 31 pour provoquer la remontée dudit feuillet 50. Celui-ci vient coopérer avec un déflecteur 51, l'orientant en direction de deux couples de rouleaux plaqueur, respectivement 14, 15 et 16, 17, induisant sa progression au sein de l'unité fonctionnelle. Ledit feuillet 50 est alors détecté (figure 10c) par une nouvelle cellule de détection 21, en l'espèce constituée par un capteur à fourche, qui va permettre d'assurer le traitement ultérieur du feuillet avec toute la précision requise dans la mesure où il détermine précisément le bord d'attaque dudit feuillet et par suite la position exacte du feuillet en comptant le nombre de pas du moteur pas à pas 31. Lorsque la feuille est en position adéquate, cela provoque l'actionnement de l'unité de rainage 18 qui, en fonction de la nature du feuillet va induire la réalisation d'une seule rainure (feuillet intermédiaire) ou de quatre rainures (feuillet de couverture).The sheet thus detected is thus supported by the pair of rollers 10 and 11, which induces its descent into the rear area of the functional unit 4. When the sheet has been fully supported by the pair of rollers 10 and 11, the detection cell 12 induces the reversal of the direction of rotation of the motor 31 to cause the rise of said sheet 50. It cooperates with a deflector 51, orienting it towards two pairs of roller platers, respectively 14, 15 and 16, 17, inducing its progression within the functional unit. Said sheet 50 is then detected ( figure 10c ) by a new detection cell 21, in this case constituted by a fork sensor, which will allow to ensure the subsequent processing of the sheet with all the required precision insofar as it precisely determines the leading edge of said sheet and therefore the exact position of the sheet by counting the number of steps of the stepper motor 31. When the sheet is in the proper position, it causes the actuation of the creasing unit 18 which, depending on the nature of the sheet will induce the realization of a single groove (intermediate sheet) or four grooves (cover sheet).

Cette unité de rainage est davantage décrite en relation avec la figure 5. Celle-ci est constituée d'une matrice 60 et d'un poinçon 61 destiné à coopérer avec cette dernière, ledit poinçon étant monté à l'extrémité d'un bras 62 articulé en 63 sur le bâti de l'unité fonctionnelle 4, et maintenu en position non opérationnelle au moyen d'un ressort 64 solidarisé audit bâti. De manière connue, le poinçon est muni d'une zone 65 en saillie linéaire, propre à coopérer avec une fente 66 ménagée au sein de la matrice 60, afin d'assurer le rainage du feuillet transitant entre les deux.This creasing unit is further described in connection with the figure 5 . This consists of a die 60 and a punch 61 intended to cooperate with the latter, said punch being mounted at the end of an arm 62 articulated at 63 on the frame of the functional unit 4, and maintained in nonoperational position by means of a spring 64 secured to said frame. In known manner, the punch is provided with a region 65 projecting linear, adapted to cooperate with a slot 66 formed within the matrix 60, to ensure the creasing of the slip transiting between the two.

Avantageusement, ladite matrice 60 est à fond amovible. A cet effet, elle comprend un éjecteur occupant la fente 66, ledit éjecteur étant repoussé vers le haut par deux poussoirs à ressort 67, induisant l'éjection du pli ménagé au sein du feuillet par la coopération de la zone 65 du poinçon et de la fente 66 de la matrice, et évitant ainsi l'accroche du feuillet contre le rebord de ladite fente lorsque le feuillet repart en mouvement.Advantageously, said die 60 is removable bottom. For this purpose, it comprises an ejector occupying the slot 66, said ejector being pushed upwards by two spring loaded pushers 67, inducing ejection of the fold formed in the sheet by the cooperation of the area 65 of the punch and the slot 66 of the matrix, and thus avoiding the attachment of the sheet against the edge of said slot when the leaflet starts moving.

L'actionnement du poinçon 61 en coopération avec la matrice 60 est réalisé au moyen d'une came 41 en prise directe avec l'axe moteur d'un moteur 40. Bien évidemment lors de l'opération de rainage, le feuillet est statique, les rouleaux assurant sa progression étant stoppés. Après opération de rainage, la progression des feuillets se poursuit.The actuation of the punch 61 in cooperation with the die 60 is achieved by means of a cam 41 in direct contact with the motor axis of a motor 40. Obviously during the creasing operation, the leaflet is static, the rollers ensuring its progression being stopped. After the creasing operation, the progress of the slips continues.

On a décrit en relation avec les figures 11a à 11d le traitement spécifique du feuillet de couverture. Celui-ci est le premier feuillet traité de l'album, c'est-à-dire le premier issu de l'imprimante pour la réalisation d'un album considéré. Consécutivement à l'étape de rainage, ledit feuillet de couverture 52 est réceptionné au niveau d'un bras dit de couverture 53, de forme sensiblement curviligne ou arquée, afin de favoriser la courbure dudit feuillet, ainsi qu'on peut bien l'observer notamment sur la figure 11a.We have described in relation with the Figures 11a to 11d the specific treatment of the cover sheet. This one is the first treated sheet of the album, that is to say the first one coming from the printer for the realization of a considered album. Subsequent to the creasing step, said cover sheet 52 is received at a so-called cover arm 53, of substantially curvilinear or arcuate shape, in order to promote the curvature of said sheet, as may well be observed especially on the figure 11a .

Ce bras de couverture 53 est représenté plus en détail au sein des figures 7a et 7b. Il est articulé en 54 au niveau de l'une de ses extrémités sur le bâti de l'unité fonctionnelle 4, et est actionné au moyen d'une came 56, de telle sorte à permettre son positionnement selon deux positions opérationnelles, respectivement :

  • ■ une position basse représentée sur la figure 7a, permettant de dégager l'accès d'un plateau de réception 55 au sein duquel va être positionné et conformé l'album,
  • ■ et une position haute, destinée d'une part à permettre le positionnement en attente du rabat de ladite couverture, et d'autre part la mise en place effective dudit rabat sur l'empilage constitué des feuillets intermédiaires, après positionnement et collage deux à deux de ceux-ci.
This cover arm 53 is shown in more detail within the Figures 7a and 7b . It is articulated at 54 at one of its ends on the frame of the functional unit 4, and is actuated by means of a cam 56, so as to allow its positioning in two operational positions, respectively:
  • ■ a low position represented on the figure 7a , making it possible to clear the access of a reception tray 55 within which the album will be positioned and shaped,
  • And a high position, intended on the one hand to allow the positioning of the blanket of said blanket pending, and on the other hand the effective establishment of said flap on the stack consisting of intermediate sheets, after positioning and gluing two to two of these.

A cet effet, l'extrémité libre du bras 53 est pourvue d'un rouleau 57, monté fou en rotation, et agencé de telle sorte à venir coopérer avec la troisième paire de rouleaux de descente 29 et 30, et ce pour faire remonter le rabat de couverture et pousser le rouleau 37 vers le haut et ainsi libérer le passage nécessaire à la montée du rabat.For this purpose, the free end of the arm 53 is provided with a roller 57, rotatably mounted, and arranged in such a way as to cooperate with the third pair of descent rollers 29 and 30, and to raise the cover flap and push the roller 37 upwards and thus release the passage necessary for the rise of the flap.

Ainsi, sur la figure 11a, le bras de couverture 53 est en position haute. Ce faisant, la première partie ou partie amont du feuillet 52 de couverture est réceptionnée au niveau dudit bras et vient s'infléchir sensiblement parallèlement à la courbe du bras 53. Après stockage de cette partie amont du feuillet de couverture 52 au sein du bras 53, ce dernier s'abaisse en position basse (figure 11b) sous l'action de la came 56, et le plateau de réception 55 est translaté au niveau de son lieu de positionnement et de réception des feuillets. Corolairement, cela induit la coopération du rouleau presseur arrière 28 avec ledit plateau 55, induisant la tension de la zone aval du feuillet de couverture 52, puis son plaquage sur ledit plateau. On a ainsi représenté sur la figure 11c le plaquage de la zone aval du feuillet de couverture 52 sur le plateau 55 par ledit rouleau presseur arrière 28. So, on the figure 11a , the cover arm 53 is in the up position. In doing so, the first portion or upstream portion of the cover sheet 52 is received at said arm and is bent substantially parallel to the curve of the arm 53. After storage of the upstream portion of the cover sheet 52 within the arm 53 , the latter lowers in the low position ( figure 11b ) under the action of the cam 56, and the receiving plate 55 is translated at its place of positioning and receiving the sheets. Corollary, this induces the cooperation of the rear pressure roller 28 with said plate 55, inducing the tension of the downstream zone of the cover sheet 52, then its plating on said plate. It has thus been represented on the figure 11c plating the downstream zone of the cover sheet 52 on the plate 55 by said rear pressure roller 28.

En suite de ce plaquage, le plateau 55 est translaté dans l'autre sens pour venir se positionner au niveau de son lieu de réception des autres feuillets intermédiaires (figure 11d).As a result of this plating, the plate 55 is translated in the other direction to be positioned at its place of reception of the other intermediate sheets ( figure 11d ).

On a décrit en relation avec les figures 12a et 12f le traitement des feuillets intermédiaires c'est-à-dire hors feuillet de couverture. Consécutivement à l'étape de rainage d'ores et déjà décrite, le feuillet intermédiaire subit tout d'abord un recul par inversion du sens de rotation du moteur 31 et ainsi pris en charge par les couples, de rouleaux respectivement 14, 15 et 16, 17 notamment aux fins d'assurer le début de la phase d'encollage (figure 12a).We have described in relation with the Figures 12a and 12f the processing of the intermediate sheets, that is to say outside the cover sheet. Following the creasing step already described, the intermediate sheet first undergoes a reversal by reversing the direction of rotation of the motor 31 and thus supported by the pairs of rolls 14, 15 and 16, respectively. , 17 in particular with a view to ensuring the beginning of the sizing phase ( figure 12a ).

Selon l'invention, seule la moitié de la face envers ou verso de chacun des feuillets intermédiaires est encollée, à l'exception du .dernier feuillet intermédiaire, qui lui est encollé sur l'intégralité de son verso, afin de permettre ensuite le collage du dos de couverture. Plus particulièrement, seule la moitié de la zone amont de la face envers de chacun des feuillets en question est effectivement encollée.According to the invention, only half of the reverse or reverse side of each of the intermediate sheets is glued, with the exception of the last intermediate sheet, which is glued to it on the entire back, in order to then allow gluing. back cover. More particularly, only half of the upstream area of the back side of each of the sheets in question is effectively glued.

A cet effet (figure 12b), l'unité d'encollage est activée. Afm de mieux comprendre le principe de fonctionnement de cette unité d'encollage, on décrit ci-après en relation avec les figures 6a, 6b et 6c cette dite unité d'encollage.For this purpose ( figure 12b ), the gluing unit is activated. In order to better understand the principle of operation of this sizing unit, the following is described in connection with the Figures 6a, 6b and 6c this said gluing unit.

Fondamentalement, l'encollage conforme à l'invention consiste à revêtir la zone dédiée des feuillets d'un film adhésif transférable, tel que par exemple commercialisé par la société 3M ou TESA. Ce film adhésif transférable est par exemple réalisé à base d'acrylique ou vinylique ou autre. L'acrylique est cependant mieux adapté au collage pérenne de papier photographique.Basically, the sizing according to the invention consists of coating the dedicated area of the sheets with a transferable adhesive film, such as for example marketed by the company 3M or TESA. This transferable adhesive film is for example made based on acrylic or vinyl or other. Acrylic is however better suited to the permanent collage of photographic paper.

Ce film adhésif est stocké sur un support non adhésif, par exemple réalisé en papier enduit de silicone, l'ensemble étant lui-même stocké sur une bobine 34, montée folle en rotation, légèrement freinée dans sa rotation, et constituant l'un des consommables de l'installation. Cette bobine est reçue dans des logements dédiés à cet effet, ménagés au sein du bâti de l'unité fonctionnelle 4. This adhesive film is stored on a non-adhesive support, for example made of paper coated with silicone, the assembly being itself stored on a coil 34, mounted idle in rotation, slightly braked in its rotation, and constituting one of the consumables of the installation. This coil is received in dedicated housing provided in the frame of the functional unit 4.

Le support siliconé dépourvu de film adhésif, c'est-à-dire après opération d'encollage, est quant à lui stocké sur une bobine 35, reçue également au sein de logements dédiées à cet effet. Celle-ci est mue en rotation à l'aide d'un moteur à courant continu qui engrène directement sur la bobine 35 grâce à un pignon denté, afin d'assurer le rembobinage du support silicone sur elle-même. Elle est également escamotable hors de l'installation après usage.The silicone support without adhesive film, that is to say after sizing operation, is stored on a reel 35, also received in dedicated housing for this purpose. This is rotated using a DC motor which meshes directly on the coil 35 by means of a toothed pinion, to ensure the rewinding of the silicone support on itself. It is also retractable out of the installation after use.

De fait, et ainsi qu'on peut l'observer notamment sur la figure 1, ces deux bobines 34 et 35 sont aisément accessibles une fois la porte 2 ouverte et le bras d'encollage 71, 74, 75 déverrouillé et relevé conformément à la figure 6c, pour ainsi faciliter les opérations de maintenance.In fact, and as can be seen in particular on the figure 1 these two coils 34 and 35 are easily accessible once the door 2 is open and the gluing arm 71, 74, 75 is unlocked and raised in accordance with the Figure 6c , to facilitate the maintenance operations.

Le support muni du film adhésif 36 est pris en charge par un rouleau motorisé 22 dit rouleau moteur de colle. La motorisation de ce dernier est assurée par un moteur électrique spécifique 70, susceptible de tourner dans les deux sens. Le rouleau 22, assurant donc le déroulement dudit support muni du film adhésif 36 depuis la bobine 34, coopère avec un rouleau encolleur 24, monté sensiblement à l'extrémité d'un levier 71 articulé en 72 sur le bâti de l'unité fonctionnelle 4, ledit levier étant maintenu en position opérationnelle à l'aide d'un ressort 73, dont l'un des points d'application est également constitué par le bâti (voir figures 6a et 6b).The support provided with the adhesive film 36 is supported by a motorized roller 22 said motor roller glue. The motorization of the latter is provided by a specific electric motor 70, capable of rotating in both directions. The roller 22, thus ensuring the unwinding of said support provided with the adhesive film 36 from the coil 34, cooperates with a gluing roll 24, mounted substantially at the end of a lever 71 articulated at 72 on the frame of the functional unit 4, said lever being held in operative position by means of a spring 73, the one of the points of application is also constituted by the frame (see Figures 6a and 6b ).

Ledit levier 71 est en outre susceptible d'être partiellement escamoté hors de sa position opérationnelle au moyen d'une poignée 75, que l'on peut également observer sur la figure 1, et reliée audit levier 71 par des traverses 74. L'ensemble constitué par le levier 71, la poignée 75 et les traverses 74 forme le bras d'encollage, mentionné précédemment.Said lever 71 is also likely to be partially retracted out of its operating position by means of a handle 75, which can also be observed on the figure 1 , and connected to said lever 71 by cross members 74. The assembly constituted by the lever 71, the handle 75 and the cross-members 74 forms the sizing arm mentioned above.

Ainsi, lorsque l'opérateur de maintenance souhaite procéder au changement des consommables d'encollage, et notamment des bobines 34 et 35, il exerce une poussée vers le haut puis une traction sur la poignée 75, induisant alors la rotation du levier 71 autour de son axe d'articulation 73 (voir figure 6c qui illustre l'unité d'encollage en position ouverte), permettant alors de libérer le support du film adhésif et corollairement d'enlever l'intégralité des éléments 34 et 35. Thus, when the maintenance operator wishes to proceed with the change of the sizing consumables, and in particular of the coils 34 and 35, he exerts an upward thrust and then a pull on the handle 75, then inducing the rotation of the lever 71 around its hinge pin 73 (see Figure 6c which illustrates the gluing unit in the open position), then allowing to release the support of the adhesive film and corollary to remove the entirety of the elements 34 and 35.

Ledit rouleau encolleur 24, monté à l'extrémité du levier 71 opposée à l'axe d'articulation 73, est susceptible d'engrener sur le rouleau de colle motorisé 22. Il est donc muni à cet effet d'une roue dentée coopérant avec une roue dentée dont est muni le rouleau 22 ces différents éléments n'étant pas représentés afin de ne pas surcharger inutilement les figures.Said gluing roller 24, mounted at the end of the lever 71 opposite to the hinge pin 73, is capable of meshing with the motorized glue roll 22. It is therefore provided for this purpose with a toothed wheel co-operating with a toothed wheel which is provided with the roller 22 these different elements not being shown so as not to unnecessarily overload the figures.

Le rouleau encolleur 24 est monté sur le levier 71 selon le principe de la roue libre. En d'autres termes, il est susceptible de tourner dans un sens seulement, étant bloqué dans le sens de rotation inversé. Dans une telle hypothèse, et en raison de son blocage, il va subir une rotation par rapport au centre de rotation du rouleau de colle motorisé 22 et donc autour de ce dernier, en raison de l'engrènement sur ledit rouleau de colle motorisé 22. Cette rotation est rendue possible, nonobstant sa solidarisation sur l'extrémité du levier 71 de par la présence d'une lumière 76 ménagée au voisinage de ladite extrémité, permettant un basculement du levier 71 malgré son verrouillage par la poignée 75. C'est ce qui a été représenté en relation avec la figure 6b, qui illustre l'unité d'encollage en position d'attente, alors même que la figure 6a représente la même unité en position d'encollage effectif. Lorsque le moteur 70 se remet à tourner dans le sens de l'encollage, le retour en position d'encollage se fait également grâce à l'action d'un ressort 77, en appui sur la traverse 74, qui repousse vers l'avant le levier 71. The gluing roll 24 is mounted on the lever 71 according to the principle of the freewheel. In other words, it is rotatable in one direction only, being locked in the direction of inverted rotation. In such a case, and because of its blocking, it will be rotated relative to the center of rotation of the motorized glue roll 22 and therefore around the latter, because of meshing on said motorized glue roll 22. This rotation is made possible, notwithstanding its attachment to the end of the lever 71 by the presence of a light 76 formed in the vicinity of said end, allowing the lever 71 to tilt despite being locked by the handle 75. who was represented in relation to the figure 6b , which illustrates the sizing unit in the waiting position, even though the figure 6a represents the same unit in actual sizing position. When the motor 70 starts to rotate in the direction of the gluing, the return to gluing position is also done through the action of a spring 77, resting on the cross 74, which pushes forward the lever 71.

Enfin l'unité d'encollage comporte un rouleau 23 assurant le rôle de butée d'encollage, c'est-à-dire remplissant la fonction de contre-réaction lors de la phase effective d'encollage sur le feuillet considéré en réponse à l'action positive du rouleau encolleur 24. Finally, the sizing unit comprises a roller 23 acting as a sizing abutment, that is to say, filling the counter-reaction function during the actual sizing phase on the sheet considered in response to the sizing. positive action of the gluing roller 24.

Ainsi, au sein de la figure 12b, le rouleau encolleur 24 est remonté et coopère avec le rouleau de butée d'encollage 23 entre lesquels progresse la zone du feuillet considéré. Ce faisant, le rouleau encolleur 24 transfère de manière effective le film adhésif sur cette zone considérée.So, within the figure 12b , the gluing roller 24 is raised and cooperates with the sizing stop roller 23 between which progresses the area of the sheet considered. In doing so, the glue roll 24 effectively transfers the adhesive film to that area.

Lorsque la zone amont a été intégralement encollée, le bord libre amont dudit feuillet vient prendre appui contre des butées 80, dont est muni le plateau de réception 55. When the upstream zone has been fully glued, the upstream free edge of said sheet bears against stops 80, which is provided with the receiving plate 55.

Le moteur 70 spécifique à l'unité d'encollage est inversé, induisant, en raison du montage en roue libre du rouleau encolleur 24, la rotation de ce dernier autour du rouleau moteur de colle 22, et partant le recul de celui-ci (figure 12c) puisqu'aussi bien celui-ci ne peut pas tourner en sens inverse. Ce faisant, la combinaison de la progression du feuillet considéré et du recul de ce rouleau induit une coupure nette du film adhésif, évitant ainsi le dépôt intempestif d'adhésif avec les conséquences dommageables susceptibles d'en résulter.The motor 70 specific to the sizing unit is inverted, inducing, due to the free-wheel assembly of the gluing roller 24, the rotation of the latter around the glue motor roller 22, and consequently the retreat thereof ( figure 12c ) since this one can not turn in the opposite direction. In doing so, the combination of the progression of the sheet considered and the retreat of this roller induces a clean cut of the adhesive film, thus avoiding inadvertent adhesive deposition with the damaging consequences that may result.

Corollairement, ainsi que représenté sur les figures 12b, 12c et 12d, le plateau de réception 55 progresse en direction de l'avant de l'unité fonctionnelle 4, et le feuillet considéré, et plus particulièrement sa zone amont alors encollée est soumis à l'action du rouleau presseur avant 32, assurant non seulement le plaquage de cette zone amont sur la première partie du feuillet de couverture mais également son collage effectif sur celle-ci.As a corollary, as represented on the Figures 12b, 12c and 12d , the receiving plate 55 progresses towards the front of the functional unit 4, and the sheet considered, and more particularly its upstream area then glued is subjected to the action of the front pressure roller 32, ensuring not only the plating this upstream zone on the first part of the cover sheet but also its actual bonding thereon.

Le sens de progression du plateau 55 de réception est alors à nouveau inversé, et ce dernier retourne en direction arrière de l'unité fonctionnelle, de sorte qu'en raison de la poursuite de la progression de la zone aval du feuillet, outre de la rainure réalisée antérieurement, on induit ainsi la pliure dudit feuillet, pliure qui va être prise en charge par le rouleau presseur arrière 26 ainsi qu'on peut l'observer sur la figure 12e.The direction of progression of the receiving plate 55 is then reversed again, and the latter returns in the backward direction of the functional unit, so that due to the continued progression of the downstream zone of the sheet, in addition to the groove made previously, thereby inducing the folding of said sheet, fold which will be supported by the rear pressure roller 26 as can be observed on the figure 12e .

Il est rappelé que la zone aval dudit feuillet n'est quant à elle pas encollée. Le recul du plateau de réception 55 s'effectue jusqu'au dégagement du feuillet des organes assurant sa progression. Le plateau de réception 55 subit une nouvelle inversion de progression pour revenir se positionner en zone de réception du ou des feuillets suivants (figure 12f), qui subissent consécutivement le même cheminement.It is recalled that the downstream zone of said sheet is not glued. The decline of the receiving plate 55 is effected until the release of the sheet of bodies ensuring its progression. The receiving tray 55 undergoes a new inversion of progression to return to position itself in the receiving area of the following sheet (s) ( figure 12f ), which follow the same path consecutively.

On a représenté avec les figures 13a à 13e le rabat du dos de couverture. Il est rappelé que ledit rabat était provisoirement stocké au sein du bras de couverture 53 (cf. figures 11a à 11d). Ainsi donc, après réalisation d'un empilement constitué de l'ensemble des feuillets intermédiaires successivement positionnés et encollés conformément aux figures 12a à 12f, le plateau de réception 55 est translaté en avant de l'unité fonctionnelle 4 pour ainsi permettre de libérer la rotation dudit bras de couverture 53 et notamment son positionnement en position haute (figure 13b).We have shown with figures 13a to 13e the flap of the back cover. It is recalled that said flap was provisionally stored within the cover arm 53 (cf. Figures 11a to 11d ). Thus, after completion of a stack consisting of all the intermediate sheets successively positioned and glued according to the Figures 12a to 12f , the receiving tray 55 is translated ahead of the functional unit 4 to thereby release the rotation of said cover arm 53 and in particular its positioning in the up position ( figure 13b ).

Ce faisant, en raison de la présence du rouleau 57 monté fou en rotation à l'extrémité libre dudit bras de couverture, qui vient coopérer avec le rouleau 29, et induit le passage du dos de couverture au-dessus des différents rouleaux assurant la progression des feuillets (figure 13b en début et figure 13c à la fin).In doing so, because of the presence of the roller 57 rotatably mounted at the free end of said cover arm, which cooperates with the roller 29, and induces the passage of the cover back over the various rollers ensuring the progression leaflets ( figure 13b in the beginning and figure 13c at the end).

Lorsque l'intégralité dudit dos de couverture a ainsi été retournée, le bras de couverture 53 redescend, ce qui permet au plateau de réception 55 de subir une nouvelle translation en direction de l'arrière de l'unité fonctionnelle. En raison de la prise en charge dudit rabat par les rouleaux 29 d'une part et 37 d'autre part, il est assuré une certaine tension du dos de couverture, permettant, en suite de la progression vers l'arrière dudit plateau de réception 55, le rabat correct sur l'empilement d'ores et déjà réalisé, rabat ensuite repris par le rouleau presseur arrière 28 (figure 13e).When the entirety of said cover back has been turned over, the cover arm 53 goes down, which allows the receiving plate 55 to undergo a new translation towards the rear of the functional unit. Due to the support of said flap by the rollers 29 on the one hand and 37 on the other hand, it is ensured a certain tension of the back cover, to allow, following the increase rearwardly of said receiving tray 55, the correct flap on the stack already made, then folded back by the rear pressure roller 28 ( figure 13e ).

Dans le cas précis de ce rabat du dos de la couverture, il est rappelé que le feuillet intermédiaire précédent a été encollé sur l'intégralité du son verso, contrairement aux autres feuilles intermédiaires, afin de permettre l'encollage effectif dudit dos de couverture sur celui-ci.In the specific case of this flap of the back of the cover, it is recalled that the previous intermediate sheet has been pasted on the entire backside, unlike the other intermediate sheets, to allow the actual sizing of said back cover on this one.

L'album est donc ainsi assemblé.The album is thus assembled.

La finition de l'album est décrite ci-après plus en détail en relation avec les figures 14a à 14e. Conformément à une caractéristique de l'invention, cette finition vise fondamentalement à massicoter ledit album aux fins, nonobstant les positionnements précis des différents feuillets venant en butée contre les butées 80 du plateau de réception 55, de conférer un aspect propre audit album. Au surplus, en raison du format identique du feuillet de couverture et des feuillets intermédiaires, et en raison du fait que ledit feuillet de couverture assure l'épaisseur de l'album, on observe nécessairement un décalage entre le bord libre dudit feuillet de couverture et celui des feuillets intermédiaires, d'où, la nécessité de ce massicotage afin d'assurer une tranche nette du bord libre de l'album.The finish of the album is described below in more detail in relation to the Figures 14a to 14e . According to a feature of the invention, this finish basically aims to trim the album for the purposes, notwithstanding the precise positioning of the various sheets abutting the stops 80 of the receiving plate 55, to confer a clean appearance to said album. In addition, because of the identical format of the cover sheet and the intermediate sheets, and because said cover sheet ensures the thickness of the album, there is necessarily a gap between the free edge of said cover sheet and that of intermediate sheets, hence the need for this cutting to ensure a clean slice of the free edge of the album.

A cet effet, le plateau de réception 55 progresse vers l'avant de l'unité fonctionnelle 4 et l'album est alors pris en charge par le rouleau presseur massicot 33, ainsi qu'on peut bien l'observer sur les figures 14a et 14b. La progression du plateau à ce niveau induit l'escamotage des butées 80 ainsi qu'on peut bien l'observer sur les figures 9a et 9b.For this purpose, the receiving plate 55 progresses towards the front of the functional unit 4 and the album is then taken over by the pressure roller trimmer 33, as can be observed on the Figures 14a and 14b . The progression of the plateau at this level induces the retraction of the stops 80 as can be observed on the Figures 9a and 9b .

Ainsi, on peut observer sur celles-ci que lesdites dents ou butées 80 sont en fait montées à l'extrémité d'un bras 81, lui-même articulé en 82 sur le dessous dudit plateau 55. Ce bras 81 comporte deux cames ou saillies dirigées vers le bas, respectivement une came antérieure 83 et une came postérieure 84, destinées chacune à coopérer avec un chemin de came 85, associé au plateau 55 et libre en translation par rapport à celui-ci.Thus, it can be observed on them that said teeth or stops 80 are in fact mounted at the end of an arm 81, itself hinged at 82 on the underside of said plate 55. This arm 81 comprises two cams or projections directed downwards respectively an anterior cam 83 and a rear cam 84, each intended to cooperate with a cam path 85, associated with the plate 55 and free in translation relative thereto.

Pendant toutes les phases antérieures, la came 83 coopère avec la zone supérieure plane du chemin de came 85, induisant de fait le positionnement des butées 80 en mode opérationnel. En revanche (figure 9b), lorsque le plateau de réception 55 progresse en position antérieure c'est-à-dire lors de la phase de massicotage, c'est la came 84 qui coopère avec le chemin de came 85, induisant, en raison de l'axe d'articulation sensiblement médian 82, l'escamotage des dents ou butées 80. During all the previous phases, the cam 83 cooperates with the planar upper zone of the cam path 85, thereby inducing the positioning of the stops 80 in operational mode. On the other hand ( figure 9b ), when the receiving plate 55 progresses to the anterior position, that is to say during the cutting phase, it is the cam 84 which cooperates with the cam path 85, inducing, because of the axis d substantially median articulation 82, the retraction of the teeth or stops 80.

Corollairement, en cette zone du plateau de réception 55, une butée anti-recul schématisée par la référence 86, actionnée par une came (non représentée) s'abaisse.As a corollary, in this area of the receiving plate 55, an anti-recoil stop schematized by the reference 86, actuated by a cam (not shown) is lowered.

Le sens de progression du plateau de réception 55 est de nouveau inversé, induisant la coopération de la butée anti-recul 86 avec la reliure ou dos de l'album ainsi réalisé et corollairement, son décalage dudit plateau en direction de la zone avant de l'unité fonctionnelle 4 (en direction de la droite sur la figure 14b). En d'autres termes, en raison de l'escamotage des butées 80 et de la translation du plateau 55 vers l'arrière de l'unité fonctionnelle, l'album glisse sur ledit plateau et fait saillie par rapport à son bord amont.The direction of progression of the receiving plate 55 is again reversed, inducing the cooperation of the anti-recoil stop 86 with the binding or back of the album thus produced and consequently, its offset from said plate towards the front zone of the functional unit 4 (towards the right on the figure 14b ). In other words, because of the retraction of the stops 80 and the translation of the plate 55 towards the rear of the functional unit, the album slides on said plate and protrudes with respect to its upstream edge.

On inverse alors à nouveau le sens de progression du plateau de réception 55 en direction de l'avant de l'unité fonctionnelle jusqu'à atteindre la zone d'actionnement d'un massicot 38. Celui-ci est typiquement constitué par une lame guillotine, actionnée par une came démultipliée susceptible d'assurer une pression de l'ordre de 400 daN sur la longueur de coupe. Cette lame guillotine assure donc une découpe franche du bord libre de l'album réalisé, l'album étant maintenu lors de l'action du massicot 38 par le rouleau presseur massicot 33, le plateau de réception 55 étant alors statique.The direction of progression of the receiving plate 55 is then reversed again in the direction of the front of the functional unit until it reaches the operating zone of a cutter 38. This is typically constituted by a guillotine blade. , actuated by a geared cam capable of providing a pressure of the order of 400 daN on the cutting length. This guillotine blade therefore ensures a free cut of the free edge of the album made, the album being maintained during the action of the paper cutter 38 by the pressure roller trimmer 33, the receiving plate 55 then being static.

Après le relevage de la lame guillotine constitutive du massicot, le plateau de réception 55 recule, mais en raison de la présence de la butée anti-recul 86, l'album glisse hors du plateau et est dégagé puis reçu sur un pan incliné 42 ménagé dans le fond de l'unité fonctionnelle 4, permettant l'évacuation par simple gravité dudit album en direction du réceptacle 5. After raising the guillotine blade constituting the cutter, the receiving plate 55 moves back, but because of the presence of the anti-recoil stop 86, the album slips out of the tray and is cleared and then received on an inclined flange 42 in the bottom of the functional unit 4, allowing the evacuation by gravity of said album towards the receptacle 5.

On a représenté en relation avec la figure 8 le principe général sous-tendant le fonctionnement et notamment la progression du plateau de réception 55 conformément à l'invention. Comme déjà dit, celui-ci est monté sur des glissières ou rails 90, montées sur des bras pivotant 91, à l'instar d'un parallélogramme déformable. Ces glissières sont maintenues en position haute par l'intermédiaire de ressorts 92, dont l'un des points d'application est solidarisé au bâti de l'unité fonctionnelle 4, de telle sorte, en raison de la coopération du plateau 55 avec les différents rouleaux presseurs notamment avant et arrière 28 et 32, de maintenir en pression et toujours à la même hauteur le dernier feuillet déposé, cette hauteur étant déterminée par le bas des rouleaux 28 et 32. We have shown in relation to the figure 8 the general principle underlying the operation and in particular the progression of the receiving plate 55 according to the invention. As already said, it is mounted on rails or rails 90, mounted on pivoting arms 91, like a deformable parallelogram. These slides are held in the high position by means of springs 92, one of the points of application is secured to the frame of the functional unit 4, so, because of the cooperation of the plate 55 with the different pressure rollers including front and rear 28 and 32, maintain pressure and always at the same height the last sheet deposited, this height being determined by the bottom of the rollers 28 and 32.

Ce plateau est solidaire d'une courroie crantée 93, actionnée en translation dans les deux directions par un moteur électrique dédié 94. This plate is secured to a toothed belt 93, actuated in translation in both directions by a dedicated electric motor 94.

En raison du mode particulier du traitement de la couverture, on peut réduire la longueur du plateau de manière significative par rapport au dispositif décrit dans l'art antérieur précité. Ce faisant, on gagne en compacité et en encombrement.Because of the particular mode of treatment of the cover, the length of the tray can be reduced significantly compared to the device described in the aforementioned prior art. In doing so, we gain in compactness and size.

L'installation conforme à l'invention permet de réaliser des albums photos d'épaisseurs variables pouvant typiquement aller jusqu'à 20 feuilles ou 40 pages.The installation according to the invention makes it possible to produce photo albums of variable thicknesses that can typically be up to 20 sheets or 40 pages.

Avantageusement, l'ensemble de l'installation est géré par un automate programmable ou un PC ou une logique électronique, assurant notamment l'activation des différents moteurs ainsi que le traitement des signaux transmis par les cellules de détection.Advantageously, the entire installation is managed by a programmable logic controller or a PC or an electronic logic, ensuring in particular the activation of the various motors as well as the processing of the signals transmitted by the detection cells.

Elle est donc complètement automatisée, puisque tant le massicotage que l'éjection de l'album réalisé ne nécessitent pas l'intervention d'un quelconque opérateur.It is thus completely automated, since both the trimming and the ejection of the realized album do not require the intervention of any operator.
