Description

L'invention concerne le conditionnement et le déconditionnement d'enveloppes.The invention relates to conditioning and deconditioning envelopes.

Dans le présent texte, on appelle "enveloppes", toutes les poches ou pochettes de papier, voire de carton destinés à recevoir une lettre, des feuillets, voire tout autre objet susceptible d'y contenir. De manière générale, une enveloppe est considérée par les spécialistes du domaine comme un "produit plat" et ce terme est fréquemment utilisé. En l'espèce, il s'applique à notre terme "enveloppe", laquelle présente plus ou moins, suivant sa structuration, une certaine souplesse ou flexibilité qui fait que notamment sous contrainte (par exemple, induite par une série d'enveloppes disposées les unes derrière les autres, dos à dos), une déformation née des différences d'épaisseurs existant en différents endroits de chaque enveloppe apparaít.In this text, we call "envelopes", all pockets paper bags, or even cardboard intended to receive a letter, leaflets or any other object that may contain them. Generally, an envelope is considered by specialists in the field as a "flat product" and this term is frequently used. In this case, it applies to our term "envelope", which more or less structuring, flexibility or flexibility which under stress (for example, induced by a series of envelopes arranged one behind the other, back to back), a deformation born of differences in thicknesses in different parts of each envelope appears.

Dans ce contexte, l'invention propose :

  • un bloc d'enveloppes conditionnées présentant une stabilité et/ou une planéité améliorée,
  • un ensemble de blocs d'enveloppes conditionnées sur une palette de manutention dans des conditions améliorées de maintien et/ou de stabilité et/ou de mise en blocs pour un déconditionnement futur plus aisé,
  • un procédé pour déconditionner un bloc d'enveloppes en permettant d'améliorer les conditions de chargement d'un chargeur d'une machine de traitement d'enveloppes (par exemple, une machine d'insertion),
  • une machine pour enrubanner une série d'enveloppes conditionnées conformément à l'invention,
  • et un procédé pour conditionner ainsi une telle série d'enveloppes.
In this context, the invention proposes:
  • a pack of packaged envelopes having improved stability and / or flatness,
  • a set of envelope blocks packaged on a pallet handling under improved conditions of maintenance and / or stability and / or blocking for easier unpacking future,
  • a method for deconditioning a block of envelopes by making it possible to improve the loading conditions of a loader of an envelope processing machine (for example, an insertion machine),
  • a machine for wrapping a series of envelopes conditioned in accordance with the invention,
  • and a method for packaging such a series of envelopes.

Concernant le premier aspect (bloc d'enveloppes conditionnées), l'invention propose une solution aux problèmes constatés de défaut de planéité d'une série d'enveloppes disposées les unes derrière les autres et/ou l'inadaptation du conditionnement typique en carton, en liaison en particulier avec une réduction des volumes de déchets et une diminution des temps des opérateurs qui doivent préparer les enveloppes, par exemple dans un chargeur de machine à insertion. A cet égard, il est à noter qu'améliorer le conditionnement d'une série d'enveloppes peut induire un gain notable dans le chargement des machines de traitement d'enveloppes, d'autant qu'avant d'être traitées par ces machines, les enveloppes doivent être déconditionnées. Il existe donc une synergie réelle entre le conditionnement, le déconditionnement et le traitement ultérieur de ces enveloppes.Concerning the first aspect (pack of packaged envelopes), the invention proposes a solution to the problems found by default of flatness of a series of envelopes arranged one behind the other and / or the maladaptation of the typical cardboard packaging, in connection with particularly with a reduction in waste volumes and a decrease in time of the operators who have to prepare the envelopes, for example in an insertion machine loader. In this respect, it should be noted that improving the conditioning of a series of envelopes can induce a significant gain in the loading of envelopes processing machines, especially as before being processed by these machines, the envelopes must be deconditioned. There is therefore a real synergy between conditioning, deconditioning and subsequent processing of these envelopes.

Dans ce cadre, une caractéristique importante de l'invention conseille donc l'utilisation d'un bloc d'enveloppes conditionnées comprenant :

  • une série d'enveloppes présentant une surface avant par-dessus laquelle se ferme un volet de fermeture de l'enveloppe, une surface arrière et une tranche, les enveloppes étant disposées les unes en regard des autres, par l'une et/ou l'autre des surfaces avant et arrière,
  • des cales rigides disposées de part et d'autre de ladite série d'enveloppes, en regard de la face avant ou de la face arrière des première et dernière enveloppes de la série,
  • et un moyen de maintien de la série d'enveloppes, ce moyen de maintien entourant étroitement la série d'enveloppes et les deux cales rigides.
In this context, an important feature of the invention therefore advises the use of a pack of packaged envelopes comprising:
  • a series of envelopes having a front surface over which closes a closure flap of the envelope, a rear surface and a wafer, the envelopes being arranged opposite one another, by one and / or other front and rear surfaces,
  • rigid shims disposed on either side of said series of envelopes, opposite the front face or the rear face of the first and last envelopes of the series,
  • and a holding means of the series of envelopes, this holding means closely surrounding the series of envelopes and the two rigid wedges.

Selon une autre caractéristique de l'invention, le moyen de maintien est avantageusement élastiquement déformable, hors tension exercée sur lui, et entoure dans un état élastique la série d'enveloppes et les cales rigides.According to another characteristic of the invention, the means of maintenance is advantageously elastically deformable, off exerted on it, and surrounds in an elastic state the series of envelopes and the rigid wedges.

On préfère cette solution à un bandeau de cerclage non élastique.This solution is preferred to a non-elastic banding band.

En effet, avec un moyen élastiquement déformable, on peut en particulier absorber, dans le temps, une éventuelle diminution de volume de la série d'enveloppes. Il se peut en effet qu'après coup, l'air emprisonné entre les enveloppes lors du conditionnement puisse s'évacuer progressivement et que l'on se trouve au bout d'un certain temps, avec un "retrait" du volume occupé par la série d'enveloppes. Indeed, with an elastically deformable means, it is possible to to absorb, over time, a possible decrease in the volume of the series of envelopes. It may be that after the fact, the air trapped between envelopes during conditioning can be evacuated gradually and that one is at the end of a certain time, with a "shrinkage" of the volume occupied by the series of envelopes.

En tant que solution technique préférée pour absorber une telle éventuelle diminution de volume, on conseille que le moyen de maintien comprenne un film étirable en matière plastique, utilisé dans son état élastique.As a preferred technical solution for absorbing such possible decrease of volume, it is advised that the means of maintenance includes plastic stretch film, used in its condition elastic.

Pour favoriser l'utilisation du bloc d'enveloppes conditionnées et faire notamment gagner du temps à un opérateur, en tirant un autre parti de l'utilisation d'un tel film étirable, une autre caractéristique de l'invention conseille que les cales rigides et le film de maintien de la série d'enveloppes soient transparents, ou bien que le film et/ou les cales soient pourvues d'un moyen de repérage pour fournir à l'utilisateur du bloc d'enveloppes conditionnées un repérage dans l'espace des enveloppes, lesquelles sont, dans la série, alors toutes orientées de la même manière.To promote the use of packaged envelopes and in particular to save time for an operator, by drawing another party from the use of such stretch film, another feature of the invention advises that the rigid shims and the film holding the series of envelopes transparent, or that the film and / or the holds are provided with a locating means for providing the user of the envelope block conditionned a location in the space of the envelopes, which are, in the series, then all oriented in the same way.

En relation avec ce qui précède, un problème que résout l'invention concerne justement l'exigence d'une orientation correcte de chaque bloc d'enveloppes en liaison avec en particulier la disposition de ce bloc sur le chargeur d'une machine de traitement d'enveloppes, tout particulièrement s'il s'agit non pas de pochettes, mais d'enveloppes rectangulaires à volet de fermeture situé sur l'une des plus grandes longueurs de l'enveloppe. Dans ce cas, la solution largement conseillée par l'invention consiste en ce que, au sein de la série d'enveloppes :

  • a) toutes les enveloppes sont identiquement orientées, le moyen de maintien entourant les enveloppes à l'écart du volet de fermeture, et
  • b) un repérage de l'orientation des enveloppes, y compris la position du volet de fermeture, existe :
    • du fait d'une capacité de repérer visuellement cette orientation à travers le moyen de maintien et l'une au moins des cales,
    • et/ou par l'intermédiaire de moyens de repérage identifiant cette orientation et prévus sur le moyen de maintien et/ou sur au moins une des cales.
    • In connection with the foregoing, a problem solved by the invention precisely concerns the requirement of a correct orientation of each block of envelopes in connection with in particular the disposition of this block on the charger of a processing machine. envelopes, especially if they are not pouches, but rectangular envelopes with closure flap located on one of the longest lengths of the envelope. In this case, the solution widely recommended by the invention consists in that, within the series of envelopes:
  • a) all the envelopes are identically oriented, the holding means surrounding the envelopes away from the closure flap, and
  • (b) an orientation of the orientation of the envelopes, including the position of the closure flap, exists:
    • because of an ability to visually identify this orientation through the holding means and at least one of the wedges,
    • and / or by means of identification means identifying this orientation and provided on the holding means and / or on at least one of the shims.

    • Comme déjà indiqué, l'invention s'est par ailleurs intéressée aux conditions de manutention de blocs d'enveloppes ainsi conditionnées. As already indicated, the invention has also been interested in handling conditions of envelopes blocks thus conditioned.

    Un autre aspect de l'invention concerne la manière de préparer le manutentionnage d'une série de blocs d'enveloppes conditionnées sur une palette, en assurant de bonnes conditions de stabilité, sans risque notable d'endommagement des enveloppes, voire en favorisant le travail des opérateurs pour une présentation plus rapide et plus sûre des blocs d'enveloppes en vue de leur déconditionnement et de leur mise en place dans le chargeur de la machine de traitement.Another aspect of the invention relates to the manner of preparing the handling of a series of packs of envelopes conditioned on a pallet, ensuring good conditions of stability, without any significant risk damage to the envelopes or even favoring the work of the operators for a faster and safer presentation of blocks envelopes with a view to their being deconditioned and put in place in the loader of the processing machine.

    De ce fait, une caractéristique de l'invention se rapporte à un ensemble comprenant :

    • une série de blocs d'enveloppes conditionnées tels que présentés ci-avant,
    • une palette de manutention sur laquelle reposent plusieurs blocs d'enveloppes conditionnées, disposés au moins pour certains avec un tronçon de la tranche des enveloppes et des cales desdits blocs en regard d'une surface supérieure d'appui de la palette,
    • et un moyen d'enrobage de la palette et de la série de blocs d'enveloppes disposés sur elle, ce moyen d'enrobage comprenant un film élastique étirable, étiré dans sa zone de déformation élastique.
    As a result, a feature of the invention relates to an assembly comprising:
    • a series of conditioned envelope blocks as presented above,
    • a pallet of handling on which rest blocks of packaged envelopes, arranged at least for some with a section of the edge of the envelopes and wedges of said blocks facing an upper bearing surface of the pallet,
    • and means for coating the pallet and the series of envelope blocks disposed thereon, said coating means comprising a stretchable elastic film stretched in its elastic deformation zone.

    Avantageusement, selon une caractéristique complémentaire :

    • la série de blocs d'enveloppes conditionnées se répartira sur plusieurs couches superposées,
    • un intercalaire sera interposé entre certaines au moins des couches,
    • certains au moins des blocs d'enveloppes présentant dans ce cas, au sein de la série d'enveloppes, des irrégularités de surface à un niveau supérieur et/ou inférieur du bloc, en liaison avec des tolérances de fabrication.
    Advantageously, according to a complementary characteristic:
    • the series of conditioned envelope blocks will be divided into several superimposed layers,
    • an interlayer will be interposed between at least some layers,
    • at least some of the packs of envelopes having, in this case, within the series of envelopes, surface irregularities at a higher and / or lower level of the block, in connection with manufacturing tolerances.

    Par ailleurs, selon encore une autre caractéristique, alternative ou complémentaire de la précédente, on conseille qu'à l'endroit du premier niveau de bloc d'enveloppes situé immédiatement au-dessus de la palette, les blocs d'enveloppes concernés reposent sur une surface de support pleine, non ajourée, par l'intermédiaire pour cela d'au moins une feuille intercalaire et/ou d'une surface supérieure horizontale pleine de la palette.Moreover, according to yet another characteristic, alternative or complementary to the previous one, we advise that at the place of the first Envelope block level located immediately above the pallet, the relevant envelope blocks rest on a support surface full, not perforated, for this purpose at least one sheet interlayer and / or a full horizontal top surface of the pallet.

    Un autre aspect inventif, qui peut être indépendant de ce qui précède, concerne donc un procédé pour déconditionner un dit bloc d'enveloppes.Another inventive aspect, which may be independent of what precedes, therefore relates to a method for deconditioning a said block envelopes.

    Un problème que résout le procédé de l'invention est celui de l'ouverture du moyen de maintien serré, en évitant que son retrait puisse endommager les enveloppes ou puisse altérer leur bon positionnement, par exemple en les décalant.A problem solved by the process of the invention is that of opening of the holding means tight, avoiding that its withdrawal can damage to envelopes or alter their proper positioning, for example example by shifting them.

    Une solution proposée par l'invention consiste donc en ce que pour déconditionner le(s) bloc(s) d'enveloppes :

  • a) on dispose au moins un dit bloc d'enveloppes dans un chargeur de machine de traitement d'enveloppes,
  • b) préalablement ou postérieurement à l'étape a), on retire d'une seule pièce le moyen de maintien qui enserre alors la série d'enveloppes et les cales rigides, sans donc rompre ce moyen de maintien, et on retire également les cales rigides,
  • c) puis on alimente la machine de traitement des enveloppes avec cette série d'enveloppes déconditionnées, disposées dans le chargeur.
    • A solution proposed by the invention therefore consists in that to decondition the block (s) of envelopes:
  • a) at least one said envelope block is arranged in an envelope processing machine loader,
  • b) before or after step a), the holding means is withdrawn in one piece, which then encloses the series of envelopes and the rigid blocks, without breaking the holding means, and the holds are also removed. rigid,
  • c) then feed the envelope processing machine with this series of deconditioned envelopes, arranged in the charger.

    • En particulier si le moyen de maintien est élastiquement déformable, on recommande, pour retirer ce moyen de maintien et/ou les cales rigides vis-à-vis d'une série d'enveloppes conditionnées, d'écarter le moyen de maintien et/ou les cales rigides par rapport à ladite série d'enveloppes, en maintenant malgré tout à ce moment le moyen de maintien et/ou les cales rigides en regard des surfaces avant ou arrière des enveloppes qui leur font face, puis de retirer le moyen de maintien et/ou les plaques rigides, par déplacement transversal relatif, à l'écart de ces surfaces, entre la série d'enveloppes et lesdites cales et/ou le moyen de maintien.In particular if the holding means is elastically deformable, it is recommended to remove this holding means and / or rigid shims vis-à-vis a series of packaged envelopes, to discard the holding means and / or rigid wedges with respect to said series of envelopes, while still maintaining at this time the means of maintenance and / or the rigid blocks facing the front or rear surfaces of the envelopes facing them, then removing the holding means and / or the rigid plates, by relative transverse displacement, away from these between the series of envelopes and the shims and / or the means of maintenance.

    Un autre aspect encore inventif, qui peut aussi être indépendant de ce qui précède, concerne une machine pour enrober les enveloppes et leurs cales rigides. Another aspect still inventive, which can also be independent of the foregoing, relates to a machine for coating the envelopes and their rigid holds.

    Pour cela, il est conseillé d'utiliser une machine comprenant :

    • des pinces avec des mors pour serrer la série d'enveloppes et les cales rigides,
    • et des moyens pour disposer, serré autour d'eux, un moyen de maintien de la série d'enveloppes et les cales rigides, ledit moyen de maintien étant disposé, lors de sa mise en place, autour de la série d'enveloppes, des cales rigides et des mors de la pince.
    For this, it is advisable to use a machine comprising:
    • clamps with jaws to clamp the series of envelopes and rigid wedges,
    • and means for arranging, tightly around them, means for holding the series of envelopes and the rigid wedges, said holding means being arranged, when it is put in place, around the series of envelopes, rigid wedges and jaws of the clamp.

    De préférence, certains au moins des mors de la pince seront pourvus d'une surface ayant un pouvoir glissant vis-à-vis des cales rigides et/ou du moyen de maintien, pour en faciliter le retrait après mise en place de ce moyen de maintien autour des cales et de la série d'enveloppes.Preferably, at least some of the jaws of the clamp will be provided with a surface having sliding power with respect to rigid blocks and / or holding means, to facilitate removal after setting up of this holding means around the wedges and the series of envelopes.

    Conditionner ainsi les enveloppes et les cales rigides permet d'obtenir un conditionnement fiable, rapide et peu onéreux, en particulier en liaison avec l'utilisation d'un moyen de maintien élastiquement déformable.Conditioning thus the envelopes and the rigid wedges allows to obtain a reliable, fast and inexpensive packaging, in particular in connection with the use of an elastically deformable holding means.

    Selon encore une autre caractéristique inventive de l'invention, en liaison avec la machine qui vient d'être présentée, on conseille, pour conditionner donc par enrobage la série d'enveloppes et les cales rigides de procéder comme suit :

    • on dispose la série d'enveloppes et les cales rigides entre des mors d'une pince,
    • on serre les mors pour rapprocher l'une de l'autre les cales rigides entre lesquelles la série d'enveloppes est interposée,
    • on entoure la série d'enveloppes, les cales rigides et les mors avec un moyen de maintien serré des cales et de la série d'enveloppes,
    • on desserre les mors de la pince, et
    • on retire hors de cette pince la série d'enveloppes et les cales entourées par le moyen de maintien serré.
    According to yet another inventive characteristic of the invention, in connection with the machine which has just been presented, it is advisable, to condition, therefore, by coating the series of envelopes and the rigid shims, to proceed as follows:
    • we have the series of envelopes and the rigid wedges between jaws of a clamp,
    • the jaws are tightened to bring the rigid blocks between which the series of envelopes interposed, to one another;
    • the series of envelopes, the rigid wedges and the jaws are surrounded by a means for tightly holding the wedges and the series of envelopes,
    • the jaws of the forceps are loosened, and
    • the series of envelopes and the shims surrounded by the tight holding means are removed from this clamp.

    Cette solution est particulièrement intéressante lorsqu'on utilise comme moyen de maintien serré un film étirable, son élasticité facilitant le retrait des enveloppes et des cales conditionnées, à l'écart des mors de la pince. This solution is particularly interesting when using tightening film, its elasticity facilitating the removal of envelopes and packed holds, away from the jaws of the clamp.

    Une description encore plus détaillée de l'invention va maintenant être fournie en référence aux dessins annexés donnés uniquement à titre d'exemples et dans lesquels :

    • les figures 11, 12, 13, montrent trois étapes successives d'une alternative de réalisation d'un tel déconditionnement.
    An even more detailed description of the invention will now be given with reference to the accompanying drawings given solely by way of example and in which:
    • FIGS. 1 and 2 show two packaging solutions of a batch of envelopes, according to the invention,
    • FIG. 3 shows, on a smaller scale, a batch of envelopes being conditioned by a wrapping machine,
    • FIG. 4 is an enlarged view of a detail of FIG. 3,
    • FIG. 5 shows a handling pallet filled by a whole series of conditioned envelope blocks, with an enlarged detail of a block of envelopes some of which are projecting,

    • Figures 11, 12, 13 show three successive steps of an alternative embodiment of such a deconditioning.

    Sur la figure 1, on voit un bloc 1 d'enveloppes conditionnées. Ce bloc, ou ensemble, comprend une succession d'enveloppes 3 et des cales rigides 5, 7, entre lesquelles est disposé et maintenu le lot d'enveloppes 3.In Figure 1, we see a block 1 of packaged envelopes. This block, or assembly, comprises a succession of envelopes 3 and shims rigid 5, 7, between which is arranged and maintained the batch of envelopes 3.

    Au sein de cette série, toutes les enveloppes sont, à l'image de celle repérée 3a qui a été extraite du lot, de préférence toutes identiquement disposées et orientées. Elles sont donc, pour une enveloppe intermédiaire comme l'enveloppe 3, deux à deux en contact dos à dos, soit par leur surface avant 30a, soit par leur surface arrière 30b.Within this series, all envelopes are, like identified 3a that has been extracted from the lot, preferably all identically arranged and oriented. They are therefore, for an intermediate envelope as the envelope 3, two by two in back-to-back contact, either by their front surface 30a, or by their rear surface 30b.

    Les cales de maintien de la série d'enveloppes sont avantageusement constituées par deux plaques rigides pleines, rectangulaires, par exemple des plaques planes en matière plastique transparente, ayant comme dimensions celles des enveloppes, lesquelles sont en l'espèce toutes de même dimension et sont disposées avec leur volet de fermeture 9 identiquement situé sur toutes les enveloppes du lot. Le volet 9, s'il est rabattu par-dessus une partie de la surface avant 30a, n'est pas fermé (c'est-à-dire qu'il n'est pas collé au corps de l'enveloppe puisque les enveloppes 3 du lot considéré n'ont pas encore été remplies).The holding wedges of the series of envelopes are advantageously constituted by two solid rigid plates, rectangular, for example flat plastic plates transparent, having as dimensions those of the envelopes, which are in this case all of the same size and are arranged with their shutter 9 identically located on all the envelopes of the lot. The flap 9, if folded over a portion of the front surface 30a, is not closed (that is to say, it is not glued to the body of the envelope since the envelopes 3 of the lot under consideration have not yet been fulfilled).

    Bien que la solution paraisse moins appropriée, compte tenu des multiples déformations possibles des enveloppes du lot, tout particulièrement s'il s'agit d'enveloppes souples, peu rigides, telles que les enveloppes non cartonnées, l'une et/ou l'autre des cales d'extrémité 5, 7, pourrai(en)t être constituée(s) d'un moyen autre qu'une plaque, tel par exemple qu'un cadre, avec ou sans croisillon central pour assurer la planéité des enveloppes, en partie centrale de leurs surfaces.Although the solution seems less appropriate, given the multiple possible deformations of the envelopes of the lot, especially if it is flexible envelopes, not rigid, such as envelopes not cardboard, one and / or the other of the end blocks 5, 7, may be constituted by means other than a plate, such as a frame, with or without a central brace to ensure the flatness of the envelopes, central part of their surfaces.

    On pourrait également envisager des plaques naturellement cintrées assez fines, qui atteindraient un état plan sous la tension du moyen de serrage.One could also consider plates naturally curved rather thin, which would reach a plane state under the tension of the medium Clamping.

    Autour des enveloppes du lot et des cales 5, 7, est disposé un moyen 11 de maintien serré des enveloppes du lot.Around the envelopes of the lot and holds 5, 7, is arranged a medium 11 tight hold of the envelopes of the lot.

    Ce bandeau 11 entoure étroitement les enveloppes et les plaques.This band 11 tightly surrounds the envelopes and plates.

    On aura constaté que les enveloppes sont rectangulaires. Elles présentent chacune une fine tranche 13 avec, le long de cette tranche, deux côtés opposés de plus petite longueur l et deux côtés opposés de plus grande longueur L . Il en est de même pour les plaques 5, 7.It will be found that the envelopes are rectangular. They each have a thin slice 13 with, along this slice, two opposite sides of smaller length l and two opposite sides of greater length L. It is the same for the plates 5, 7.

    Le moyen 11 de maintien serré passe le long des deux tronçons opposés de plus petite longueur l des enveloppes et des cales 5, 7, et s'étend avantageusement sur toute la petite longueur l des enveloppes et des cales.The means 11 for maintaining tight passes along the two opposite sections of shorter length the envelopes and pads 5, 7, and advantageously extends over the entire free length l envelopes and shims.

    Ainsi, une fois qu'un tel lot d'enveloppes repose sur un support d'appui de chaque tronçon inférieur de plus grande longueur L , il est bloqué latéralement par le moyen 11 et empêché, tant frontalement que dorsalement, de s'arquer, de par la présence des cales 5, 7.Thus, once such a batch of envelopes rests on a support support of each lower section of greater length L , it is blocked laterally by the means 11 and prevented, both frontally and dorsally, from arching, by the presence of shims 5, 7.

    Pour maintenir dans le temps la pression la plus efficace sur le lot d'enveloppes, le moyen 11 de maintien consiste, sur la figure 1, en un film étirable en matière plastique, tel qu'un fin film en polyéthylène. To maintain in time the most effective pressure on the batch of envelopes, the holding means 11 consists, in FIG. Stretchable plastic material, such as a thin polyethylene film.

    Il s'agit donc là d'un moyen élastiquement déformable qui, une fois placé serré autour du lot d'enveloppes et des cales 5, 7, est encore malgré dans son état élastiquement déformable, de sorte que si le lot d'enveloppes perd de son volume, il absorbe ce "retrait" en continuant à exercer malgré tout une pression de serrage sur le lot d'enveloppes et les cales d'extrémité.It is therefore an elastically deformable means which, once placed tight around the lot of envelopes and wedges 5, 7, is still despite in its elastically deformable state, so that if the batch of envelopes loses its volume, it absorbs this "withdrawal" by continuing to nevertheless, to exert a tightening pressure on the batch of envelopes and end wedges.

    Eventuellement, en substitution, on aurait pu envisager de remplacer le moyen élastiquement déformable 11 par une lanière ou un ruban plus épais, non élastiquement déformable 110, que l'on aurait simplement serré autour du lot d'enveloppes et des cales 5, 7, au moment du conditionnement d'origine (figure 2).Possibly, in substitution, we could have considered replace the elastically deformable means 11 with a strap or a thicker ribbon, not elastically deformable 110, that one would have simply tight around the lot of envelopes and holds 5, 7, at the moment original packaging (Figure 2).

    Sur la figure 2, au moins la cale 5 est transparente. Le ruban 110 l'est de préférence aussi. Un opérateur peut ainsi déceler à travers la cale 5 et la partie du ruban 110 qui la recouvre, la position du volet de fermeture 9 et ainsi vérifier si le bloc 1 conditionné est correctement orienté, notamment pour une mise en place optimisée sur le chargeur d'une machine à insertion d'enveloppes.In Figure 2, at least the shim 5 is transparent. The ribbon 110 is preferably too. An operator can thus detect through the hold 5 and the portion of the tape 110 which covers it, the position of the shutter 9 and thus check if the conditioned block 1 is correctly oriented, in particular for optimized placement on the loader of an insertion machine envelopes.

    Sur la figure 1, on a imaginé que ni les cales d'extrémité 5, 7, ni le banderolage 11 ne permettaient de repérer les volets 9 à travers eux. Aussi a-t-on prévu un moyen de repérage 12. Dans l'exemple, il s'agit d'une flèche dirigée vers le bas et imprimée sur une zone du moyen de maintien 11 s'étendant en regard de la surface extérieure de la cale 5 pour indiquer que le volet de fermeture fait face à la cale 5 le long de sa plus grande longueur inférieure (à l'image d'ailleurs de la situation du volet 9 que l'on voit par transparence sur la figure 2). Dans une autre solution, le repérage pourrait être porté sur l'une au moins des cales.In FIG. 1, it has been imagined that neither the end wedges 5, 7, nor the wrapping 11 did not identify the shutters 9 through them. As well is there a way of locating 12. In the example, it is an arrow directed downwards and printed on an area of the holding means 11 extending opposite the outer surface of the shim 5 to indicate that the closure flap faces the hold 5 along its longer length (in the same way as the situation of the shutter 9 that we see by transparency in Figure 2). In another solution, the identification could be worn on at least one of the holds.

    La figure 3 montre une solution de mise en place du film plastique étirable 11 autour du lot d'enveloppes 3 et des cales d'extrémité 5, 7.Figure 3 shows a solution for placing the plastic film stretchable 11 around the pack of envelopes 3 and the end blocks 5, 7.

    La machine 10 pour conditionner l'ensemble 1 tel qu'illustré sur la figure 2, comprend une banderoleuse 15 dans laquelle est stocké un rouleau de film étirable 111 qui, une fois enroulé de la manière déjà indiquée autour des cales 7, 5, et du lot d'enveloppes 3, constitue le banderolage 11, après rupture de la bande 111 en un endroit approprié, par exemple, par découpe via un couteau chaud (non représenté). Pour la mise sous tension du film étirable 11, un système (non représenté) de traction assure un étirement dans sa zone élastique de la partie terminale de la bande 111.The machine 10 for packaging the assembly 1 as illustrated on the FIG. 2 comprises a wrapping machine 15 in which is stored a roll of stretch film 111 which, once wound in the manner already indicated around shims 7, 5, and the batch of envelopes 3, constitutes the wrapping 11, after rupture of the strip 111 in a suitable place, for example, by cutting via a hot knife (not shown). To turn on the film stretchable 11, a system (not shown) of traction provides a stretch in its elastic zone of the end portion of the band 111.

    Comme illustré, les cales 5, 7, et le lot d'enveloppes 3 sont disposés au milieu du rouleau de film et sont supportés par la pince 17 (dont on n'a pas représenté la liaison avec le reste de la machine, par souci de simplification).As illustrated, the shims 5, 7, and the pack of envelopes 3 are disposed in the middle of the film roll and are supported by the clip 17 (of which the link with the rest of the machine has not been represented, for the sake of simplification).

    La pince comprend un mors supérieur 19 comportant en l'espèce deux plaquettes 21 a, 21 b, et un mors inférieur 23 constitué de la même manière.The clamp comprises an upper jaw 19 comprising in the present case two plates 21 a, 21 b, and a lower jaw 23 consisting of the same way.

    Les deux mors sont mobiles l'un par rapport à l'autre en translation via un système à piston 25 pour serrer dans le sens des flèches de la figure 4.The two jaws are movable relative to each other in translation via a piston system 25 to tighten in the direction of the arrows of Figure 4.

    On notera que les plaquettes de serrage des mors, telles que 21 a, 21 b, sont, au moment du banderolage, interposées entre la bande extérieure 11 et les cales rigides 5, 7 (voir notamment figure 3).It will be noted that the clamping plates of the jaws, such as 21 a, 21 b, are, at the time of wrapping, interposed between the outer band 11 and rigid shims 5, 7 (see in particular Figure 3).

    Après mise sous tension du film étirable et séparation de la bande 11 par rapport au reste du rouleau 111, on procède au retrait de l'ensemble 1 conditionné. Pour cela, les surfaces de tout ou partie des mors 19, 23, sont de préférence recouvertes d'un revêtement glissant 27 (par exemple un revêtement de Téflon®). Le revêtement peut être situé sur les faces supérieure et inférieure des plaquettes telles que 21 a, 21 b. Après retrait hors de la machine 10, on obtient le bloc d'enveloppes 1 de la figure 1 sur lequel on distingue en 29 la zone de soudure où la bande est refermée sur elle-même et à partir d'où elle a été séparée du reste du rouleau 111 de la figure 3.After tensioning the stretch film and separating the tape 11 relative to the rest of the roller 111, the removal of the whole 1 conditioned. For this, the surfaces of all or some of the jaws 19, 23, are preferably covered with a sliding coating 27 (for example a Teflon® coating). The coating can be located on the faces upper and lower platelets such as 21 a, 21 b. After withdrawal out of the machine 10, the block of envelopes 1 of FIG. we distinguish in 29 the welding zone where the band is closed on itself and from where it was separated from the rest of the roller 111 of the figure 3.

    La figure 5 montre un ensemble de blocs d'enveloppes conditionnées tels que 1, 20, 30, 40 et disposés, en piles adjacentes, sur une palette de manutention 31.Figure 5 shows a set of envelope blocks packaged such as 1, 20, 30, 40 and arranged, in adjacent piles, on a pallet of handling 31.

    Les différents blocs tels que 20, 30, sont identiques au bloc 1 de la figure 1 et sont disposés chacun de la même manière que sur la figure 1, c'est-à-dire avec un banderolage sur les parois latérales, dans le sens de la hauteur, avec les tranches supérieure et inférieure libres, une portion de tranche inférieure de plus grande longueur L des enveloppes et des cales reposant soit sur un bloc identique inférieur, soit, pour le bloc le plus inférieur, directement sur la surface supérieure 32 de la palette.The various blocks such as 20, 30, are identical to block 1 of FIG. 1 and are each arranged in the same manner as in FIG. 1, that is to say with a wrapping on the side walls, in the direction the height, with the upper and lower free edges, a lower portion of the lower portion L of the envelopes and shims resting on either an identical lower block or, for the lower block, directly on the upper surface 32 of the palette.

    Dans un certain nombre de situations, certaines enveloppes (telles que 300) d'un bloc d'enveloppes conditionnées peuvent être décalées dans le sens de la hauteur, comme le montre la vue agrandie à droite sur cette même figure 5. Plus exactement, les blocs peuvent présenter, au sein de la série d'enveloppes, des irrégularités de surface au niveau supérieur et inférieur du bloc liées à des tolérances de fabrication.In a number of situations, some envelopes (such as 300) of a pack of packaged envelopes can be shifted in the sense of height, as shown in the enlarged view to the right on this same figure 5. More exactly, the blocks can present, within of the series of envelopes, surface irregularities at the upper level and lower block related to manufacturing tolerances.

    Pour éviter des problèmes consécutifs à cette situation, des feuillets intercalaires tels que 33 sont interposés au moins entre certains des niveaux de blocs d'enveloppes conditionnées en s'étendant individuellement sur une surface plus grande que la surface supérieure ou inférieure S d'un bloc unique. L'épaisseur et la flexibilité de ces intercalaires (typiquement en papier) sont telles qu'on récupère ainsi la planéité entre les niveaux de blocs empilés, en rattrapant les irrégularités créées par ces décalages en hauteur de certaines enveloppes dans un bloc, sans pour autant endommager les enveloppes (étant entendu que le décalage est typiquement peu prononcé).To avoid problems arising from this situation, leaflets such as 33 are interposed at least between some of the packaged envelope block levels by extending individually on a larger surface than the upper or lower surface S of a single block. The thickness and flexibility of these spacers (typically in paper) are such that we recover the flatness between the block levels stacked, catching the irregularities created by these offsets in height some envelopes in a block, without damaging the envelopes (with the understanding that the offset is typically not pronounced).

    A l'endroit du plus bas niveau des piles, les blocs d'enveloppes conditionnées, tel que le bloc 40 sur la figure 5, reposent sur un plancher plein 32 constituant la surface supérieure de la palette 31.At the lowest level of the batteries, the envelope blocks packaged, such as block 40 in FIG. 5, rest on a floor full 32 constituting the upper surface of the pallet 31.

    En alternative, on peut prévoir de remplacer ce plancher plein 32 par un cloisonnage ajouré 37 formant le plancher supérieur de la palette 39 de la figure 6, avec interposition d'une série de feuillets intercalaires 35 qui, comme les feuillets intermédiaires 33, présentent chacun une surface supérieure à chaque surface individuelle S d'un bloc d'enveloppes conditionnées, et qui sont interposés, bord à bord ou avec un faible chevauchement, entre les différents blocs d'enveloppes conditionnées du niveau le plus inférieur des piles et la surface supérieure discontinue de la palette. Alternatively, it can be expected to replace this solid floor 32 by a perforated partition 37 forming the upper floor of the pallet 39 of FIG. 6, with the interposition of a series of intermediate sheets 35 which, as the intermediate leaflets 33, each have a surface greater than each individual surface S of a block of envelopes conditioned, and which are interposed, edge to edge or with a weak overlap, between the different packaged envelope blocks of the lowest level of piles and the discontinuous upper surface of the palette.

    Sur la figure 6, toutes les piles d'enveloppes conditionnées sont représentées enrobées par un film étirable de maintien 45.In FIG. 6, all the stacks of packaged envelopes are shown coated with a stretchable holding film 45.

    Sur les figures 7 à 10, on voit un premier moyen de conditionnement du bloc d'enveloppes 1, suivant plusieurs étapes de mise en oeuvre.In FIGS. 7 to 10, we see a first means of conditioning of the envelope block 1, according to several stages of setting implemented.

    Sur ces figures, comme d'ailleurs sur les figures suivantes 11 à 13, le dispositif de déconditionnement présenté va permettre de retirer le moyen de maintien 11, sans le rompre, évitant ainsi tout endommagement éventuel des enveloppes ou altération de l'ensemble relativement compact qu'elles constituent.In these figures, as in the following figures 11 to 13, the unpacking device presented will allow to remove the holding means 11, without breaking it, thus avoiding any damage possible envelopes or alteration of the relatively compact set they constitute.

    Sur la figure 7, le dispositif de déconditionnement 50 comprend un poussoir 51 monté sur vérin 53 porté par un bâti 55 dont deux bras opposés 57, 59, portent des tiges 61 a, 61 b, 61 c, 61 d, mobiles en écartement relatif, deux à deux, pour constituer des moyens d'élargissement contrôlés du bandeau 11, jusqu'à en assurer le retrait, comme on peut le voir sur la figure 9.In FIG. 7, the deconditioning device 50 comprises a pusher 51 mounted on cylinder 53 carried by a frame 55 including two opposing arms 57, 59, carry rods 61a, 61b, 61c, 61d, movable in relative spacing, two by two, to constitute controlled means of enlargement of the band 11, to ensure the withdrawal, as can be seen in the figure 9.

    De préférence, les moyens d'écartement 61a, ....., 61d, sont prévus pour agir sur le moyen de maintien 11 à l'endroit des cales d'extrémité 5, 7, évitant ainsi d'interférer avec les enveloppes, au risque de les endommager ou d'en perturber le maintien en bloc uniforme et correctement positionné.Preferably, the spacing means 61a, ....., 61d, are provided to act on the holding means 11 at the location of the holds 5, 7, thus avoiding interfering with the envelopes, at the risk of damage or disrupt the uniform blocking and correctly positioned.

    A noter que dans l'hypothèse où une ou plusieurs cerclages, comme sur la figure 2, remplaceraient le banc d'enrôlage avec le moyen élastiquement déformable 11, l'invention conseille fortement de déconditionner le bloc d'enveloppes à partir d'au moins une zone située à l'endroit des cales d'extrémité 5, 7, c'est-à-dire à l'écart des enveloppes, tout particulièrement pour les mêmes raisons que celles qui précèdent.Note that in the event that one or more strapping, as in Figure 2, would replace the enrollment bench with the medium elastically deformable 11, the invention strongly advises unpacking the envelope block from at least one zone located at the place of the end wedges 5, 7, that is to say away from the envelopes, all especially for the same reasons as above.

    Sur la figure 7, les tiges d'écartement 61a, ..., 61 d sont montées dans des glissières 63a, 63b, 63c, 63d, lesquelles sont situées au droit des extrémités longitudinales des cales d'extrémité 5, 7, respectivement.In FIG. 7, the spacer rods 61a,..., 61d are mounted in slides 63a, 63b, 63c, 63d, which are located at the right longitudinal ends of the end wedges 5, 7, respectively.

    Sur la hauteur (petite longueur) l de chacune des cales, à ces extrémités longitudinales, des rainures ouvertes 65a, 65b, 65c, 65d, permettent aux tiges 61a, ...., 61d, de venir agir sur les moyens de maintien 11, par engagement à l'intérieur des rainures ouvertes, comme on le voit sur la figure 7.On the height (small length) l of each of the wedges, at these longitudinal ends, open grooves 65a, 65b, 65c, 65d, allow the rods 61a, ...., 61d, to act on the holding means 11 , by engagement within the open grooves, as seen in Figure 7.

    Dans cette position, l'ensemble du bâti 55 avec les tiges 61a, ...., 61 d, a été rapproché du bloc d'enveloppes 1 conditionnées et le poussoir 51 est en appui contre une tranche commune de plus grande longueur L de l'ensemble du bloc d'enveloppes et des deux cales d'extrémité 5, 7, de manière à les plaquer, sous l'effet du vérin 53, contre leur surface opposée d'appui 67 (action dans le sens de la flèche 69 sur la figure 8). La surface 67 peut constituer le fond 'un chargeur d'une machine à insertion d'enveloppes.In this position, the assembly of the frame 55 with the rods 61a, ...., 61 d, has been brought closer to the pack of packaged envelopes 1 and the pusher 51 is in support against a common slice of greater length L of the entire block of envelopes and two end blocks 5, 7, of in order to flatten them, under the effect of the jack 53, against their opposite surface support 67 (action in the direction of the arrow 69 in Figure 8). The surface 67 can constitute the bottom a charger of an envelope insertion machine.

    Dans cette position, les tiges d'écartement 61a, ...., 61d, sont en position "escamotée", à l'extrémité arrière de leur glissière (respectivement 63a, ..., 63d.In this position, the spacer rods 61a, ...., 61d, are in "retracted" position, at the rear end of their slide (respectively 63a, ..., 63d.

    Le moyen 11 étirable de maintien n'est pas surétiré.Stretchable holding means 11 is not over stretched.

    Il l'est par contre sur la figure 9 où le dispositif 50 est dans la même position que sur la figure 8, à l'exception des tiges d'écartement 61a, ...., 61d, qui sont maintenant en position "active", sorties des rainures ouvertes 65a, ....., 65d, pour pousser le moyen étirable 11 à l'écart de la tranche de deux côtés opposés de plus petite longueur du lot d'enveloppes (en l'espèce, en étirant le film 11 suivant les deux sens opposés 71 a, 71 b, suivant une même direction).It is, however, in FIG. 9 where the device 50 is in the same position as in FIG. 8, with the exception of the spacer rods 61a, ...., 61d, which are now in the "active" position, outputs of the grooves open 65a, ....., 65d, to push the stretchable means 11 away from the slice of two opposite sides of smaller length of the envelope lot (in this case, stretching the film 11 in the two opposite directions 71a, 71b, following the same direction).

    Il ne reste plus ensuite qu'à relever l'ensemble du bâti 55, y compris donc les tiges 61a, 61b, .... qui maintiennent alors le bandeau étirable 11, tout en plaquant toujours sur leur surface d'appui 67 le lot d'enveloppe 3 et les cales 5, 7, par l'intermédiaire du poussoir 51 et du déploiement de la tige du vérin 53 dans le sens de la direction 72 (voir figure 10).All that remains is to lift the entire building 55, including therefore included the rods 61a, 61b, .... which then maintain the headband stretchable 11 while still plating on their support surface 67 the batch 3 and the shims 5, 7, via the pusher 51 and the deployment of the cylinder rod 53 in the direction of the direction 72 (see FIG. 10).

    Il ne reste plus alors qu'à retirer les deux cales d'extrémité 5, 7.It then remains only to remove the two end blocks 5, 7.

    Sur les figures 11, 12, 13, une variante de réalisation d'un dispositif de déconditionnement, 70, a été illustrée. Il se distingue du dispositif 50 par la direction des rainures 73a, 73b, 73c, 73d, suivant lesquelles se déplacent les tiges d'écartement 61a, ..., 61d (étant précisé que sur cette figure, on a attribué les mêmes repères aux mêmes moyens que ceux décrits en relation avec le dispositif de déconditionnement 50).In FIGS. 11, 12, 13, an alternative embodiment of a deconditioning device, 70, has been illustrated. It is different from device 50 by the direction of the grooves 73a, 73b, 73c, 73d, following which move the spacer rods 61a, ..., 61d (being specified that in this figure, the same references have been attributed to the same means than those described in relation to the deconditioning device 50).

    En l'espèce, les rainures 73a, ...., sont dirigées de biais pour assurer un écartement du moyen de maintien 11 sur les quatre côtés latéraux du bloc d'enveloppes conditionnées 100, lorsque toutes les tiges d'écartement 61a, ...., agissent de façon conjuguée.In this case, the grooves 73a, ...., are directed at an angle to ensure a spacing of the holding means 11 on all four sides side of the pack of conditioned envelopes 100, when all the stems spacers 61a, ...., act in conjunction.

    A noter également sur les figures 11 à 13, une autre particularité consistant en la possibilité de retirer, dans une unique opération, à la fois le moyen 11 élastiquement déformable et les cales d'extrémité 5, 7, à l'écart du lot d'enveloppes 3.Also note in Figures 11 to 13, another feature consisting in the possibility of withdrawing, in a single operation, both the elastically deformable means 11 and the end blocks 5, 7, away from the lot of envelopes 3.

    Bien entendu, l'écartement des quatre côtés du film étirable par les rainures en biais 73a, ..., peut être dissocié du retrait simultané des cales.Of course, the spacing of the four sides of the stretch film by the angled grooves 73a,... can be dissociated from the simultaneous withdrawal of shims.

    Cela étant, pour tout retrait automatisé de ces cales d'extrémité 5, 7, il doit être clair que l'invention prévoit des zones délimitées d'appui pour les moyens de retrait (tels que 61a, ..., 61d), qu'il s'agisse du retrait du moyen de maintien 11 seul, ou du retrait conjugué de ce moyen de maintien et des cales (comme sur la figure 13).That being so, for any automated removal of these end shims 5, 7, it must be clear that the invention provides delimited areas of support for the withdrawal means (such as 61a, ..., 61d), whether the withdrawal of the holding means 11 alone, or the conjugate withdrawal of this holding means and shims (as in Figure 13).

    En effet, il importe alors que ces cales d'extrémité 5, 7, soient localement conformées pour recevoir l'appui sur elles soit de moyens de poussée (comme les tiges 61a, ...,) soit de moyens de traction (non représentés ici) qui permettent, à l'endroit de ces cales, d'agir au moins sur le moyen de maintien 11 (pour l'éloigner du lot d'enveloppes 3), voire sur l'ensemble constitué par ce moyen 11 et les cales 5, 7, pour, ensemble, les éloigner du lot d'enveloppes, comme sur la figure 13.Indeed, it is important that these end blocks 5, 7, are locally conformed to receive support on them either means of thrust (as the rods 61a, ...,) is traction means (no represented here) which allow, at the location of these holds, to act at least on the holding means 11 (away from the batch of envelopes 3) or on the assembly constituted by this means 11 and the shims 5, 7, for, together, the away from the package of envelopes, as in Figure 13.

    Sur les figures 7 à 10, lesdites zones délimitées d'appui réservées sur les cales d'extrémité 5, 7, sont constituées par les rainures ouvertes 65a, ..., 65d. Sur les figures 11 à 13, on retrouve des rainures ouvertes 75a, ..., 75d situées sur la hauteur l des cales, à leurs extrémités longitudinales opposées, mais ces rainures sont ici formées à l'endroit de l'angle intérieur de ces extrémités des cales, pour réserver un rebord extérieur d'appui 77, à chaque extrémité, permettant d'écarter le moyen 11 par l'intermédiaire d'une action sur des zones ainsi limitées.In FIGS. 7 to 10, said defined support zones reserved on the end wedges 5, 7 are constituted by the open grooves 65a,..., 65d. In FIGS. 11 to 13, there are open grooves 75a,..., 75d located on the height l of the wedges, at their opposite longitudinal ends, but these grooves are here formed at the location of the internal angle of these wedge ends, to reserve an outer bearing flange 77, at each end, to separate the means 11 through an action on areas thus limited.

    A noter qu'éventuellement, ces zones délimitées d'appui pourraient être situées ailleurs sur les cales et/ou conformées autrement, si nécessaire en liaison avec des moyens d'écartement autres que les tiges 61a, ..., même si ces moyens facilitent l'automatisation du déconditionnement. Ainsi, on pourrait par exemple envisager la présence, sur les cales d'extrémité, de pattes en saillies accessibles aux doigts d'un opérateur et permettant d'assurer le déconditionnement du lot d'enveloppes 3, manuellement.Note that eventually these demarcated areas of support could be located elsewhere on holds and / or otherwise shaped, if necessary in connection with spacer means other than rods 61a, ..., even if these means facilitate the automation of deconditioning. Thus, one could for example consider the presence, on the end wedges, protruding legs accessible to the fingers of a operator and to ensure the deconditioning of the batch of envelopes 3, manually.

    Sur les figures 11 à 13, on aura également noté la présence, sur chaque cale d'extrémité 5, 7, d'une découpe 79 qui peut se présenter comme une gorge verticale (voir figure 13) et qui évite que le barreau d'appui 51 agisse sur les cales.In FIGS. 11 to 13, the presence, on each end wedge 5, 7, of a cutout 79 that can be presented as a vertical groove (see figure 13) and which prevents the support bar 51 act on the holds.

    Ainsi, une fois les tiges de poussée 61 a, ..., engagées devant les rebords 77, ces tiges sont activées, tandis que le barreau 51 appuie sur les enveloppes (figure 12). Tant les deux cales d'appui 5, 7, que le moyen de maintien 11 étirable, sont alors écartés du lot d'enveloppes 3. Il ne reste plus qu'à écarter ce lot d'enveloppes 3 du reste (voir figure 13).Thus, once the push rods 61 a, ..., engaged before the edges 77, these rods are activated, while the bar 51 presses the envelopes (Figure 12). Both the support wedges 5, 7, the means of 11 stretchable, are then removed from the batch of envelopes 3. There is no longer any than to discard this batch of envelopes 3 from the rest (see Figure 13).

    Sur aucune des figures montrant les éléments principaux du dispositif de déconditionnement 50, 70, n'ont été illustrés les bâtis ou moyens annexes de support ou d'actionnement (moteur, tringlerie, ...) permettant par exemple aux tiges de poussées 61a, ..., de passer de leur position escamotée à leur position active. Ces moyens sont à la portée de l'homme du métier et sont en eux-mêmes connus.In none of the figures showing the main elements of the deconditioning device 50, 70, have been illustrated the frames or ancillary means of support or actuation (engine, linkage, ...) allowing for example push rods 61a, ..., to pass from their retracted position to their active position. These means are within the reach of the skilled person and are known in themselves.
