The invention is applied in particular to the adhesive strips for affixing the flaps of packets of paper handkerchiefs. A strip of flexible material such as polyethylene is previously marked with a discontinuous cutting line which traces the outline of the flap, the adhesive strips are laid on the strip acrossthe flaps, and then the film is cut, transversally to its direction of motion into individual sheets (3) in which the packets (2) are wrapped.

Description

DISPOSITIF POUR ENVELOPPER DES PRODUITS DANS DES ETUIS DEVICE FOR WRAPPING PRODUCTS IN CASES
AVEC ETIQUETTEWITH LABEL
L'invention se rapporte à un dispositif pour emballer des produits dan une feuille en matière souple, avec une étiquette appliquée extérieure¬ ment sur l'une de ses faces.The invention relates to a device for packaging products in a sheet of flexible material, with a label applied externally on one of its faces.
Elle s'applique en particulier aux mouchoirs en ouate de cellulose, plies en accordéon, et conditionnés dans un étui parallélepipedique en matière plastique ou en papier.It applies in particular to handkerchiefs made of cellulose wadding, folded into an accordion, and packaged in a parallelepipedal case made of plastic or paper.
Afin de préserver la propreté des mouchoirs après l'ouverture du paquet, il est déjà connu de pourvoir l'ouverture de distribution d'un rabat convenablement découpé sur 1*enveloppe.In order to preserve the cleanliness of the handkerchiefs after opening the package, it is already known to provide the dispensing opening with a flap suitably cut out of the envelope.
Ce volet est délimité par une ligne de perforations que l'on déchire au moment où l'on veut extraire le premier mouchoir. La forme de cette ligne, par exemple en arc de cercle avec une zone d'amorçage de la découpe, permet ainsi le dégagement partiel de l'une des faces de l'étui par pliage autour de l'axe formé par la ligne passant par les extrémités de la découpe.This shutter is delimited by a line of perforations which one tears at the time when one wants to extract the first handkerchief. The shape of this line, for example in an arc of a circle with a zone for initiating the cut, thus allows the partial release of one of the faces of the case by folding around the axis formed by the line passing through the ends of the cut.
Une languette adhesive, solidaire du volet par une extrémité, sert d'attache amovible et le maintient en position rabattue quand on n'a pas besoin dé mouchoirs. L'extrémité de la languette opposée au rabat peut comporter une partie de surface non adhesive pour faciliter la préhen- sion et permettre la réouverture du- paquet.An adhesive tab, secured to the flap at one end, serves as a removable fastener and keeps it in the folded position when tissues are not needed. The end of the tab opposite the flap may have a non-adhesive surface portion to facilitate gripping and allow the package to be reopened.
L'invention a pour objet un procédé permettant de réaliser industriel¬ lement ce type de conditionnement avec languette ou, plus généralement, avec une étiquette rapportée extérieurement sur une face.The subject of the invention is a process allowing this type of packaging to be produced industrially with a tongue or, more generally, with a label attached externally to one face.
Les installations connues de la Demanderesse comportent un dispositif de pose par transfert d'étiquettes, placé en aval du poste où sont enve¬ loppés les paquets de mouchoirs dans leur étui.The installations known to the Applicant include a device for applying labels by transfer, placed downstream from the station where the packages of tissues are wrapped in their case.
Ainsi, la mise en place des étiquettes intervient en dernière phase de fabrication. Cette organisation des différentes étapes de confection des étuis, à priori la plus simple, conduit à l'adjonction en bout de machine d'un dispositif de pose des étiquettes encombrant et assez complexe. En effet, il faut positionner avec précision, par des moyens mécaniques, chaque étui par rapport à l'organe de transfert des étiquettes. Le cas échéant, si on. désire poser l'étiquette sur une face qui n'est pas la face supérieure telle qu'elle sort du poste de confection des étuis, il est nécessaire d'adjoindre un mécanisme de retournement et de position¬ nement supplémentaire. En outre, le support des étiquettes étant mou - un paquet de mouchoirs en papier - un adhésif à tack élevé est indis¬ pensable pour réduire au maximum la pression exercée au moment du trans¬ fert, et limiter les risques d'endommagement du produit et de pose défectueuse. Le coût de fabrication s'en trouve augmenté.Thus, the establishment of the labels occurs in the last phase of manufacture. This organization of the various stages of making of cases, a priori the simplest, leads to the addition at the end of the machine of a device for applying the bulky and fairly complex labels. Indeed, it is necessary to position with precision, by mechanical means, each case relative to the label transfer member. If so, if one. wishes to place the label on a face which is not the upper face as it leaves the case-making station, it is necessary to add an overturning and additional positioning mechanism. In addition, the support for the labels being soft - a packet of tissues - a high tack adhesive is essential to reduce as much as possible the pressure exerted at the time of transfer, and limit the risks of damage to the product and defective installation. The manufacturing cost is increased.
On peut s'affranchir de ces problèmes en modifiant l'ordre dans lequel sont accomplies certaines des tâches, notamment en rapportant l'éti¬ quette sur la feuille avant que l'on enveloppe le paquet de mouchoirs avec celle-ci. De préférence on va apposer les étiquettes à Intervalles réguliers sur la bande destinée à l'enveloppage puis séparer les feuilles et -former les étuis.These problems can be overcome by modifying the order in which some of the tasks are carried out, in particular by bringing the label on the sheet before wrapping the packet of tissues with it. Preferably, we will affix the labels at regular intervals on the strip intended for wrapping, then separate the sheets and form the cases.
Grâce à cette disposition :Thanks to this arrangement:
L'étiquette n'est plus apposée sur un produit mou, il suffit de pré¬ voir un support rigide de la feuille, en regard de l'organe de pose. Il s'ensuit une plus grande fiabilité et une meilleure précision.The label is no longer affixed to a soft product, it suffices to pre¬ see a rigid support for the sheet, facing the fitting member. This results in greater reliability and better precision.
On peut utiliser un adhésif de qualité standard, un faible tack suffit.Standard quality adhesive can be used, low tack is sufficient.
On dispose d'une plus grande liberté de choix pour l'emplacement de l'étiquette. En effet, la feuille devant constituer l'emballage du produit est, à ce moment, développée à plat sous la forme d'une bande continue. Comme elle est en défilement par rapport à l'organe de pose, un simple réglage des paramètres respectifs d'entraînement suffit.There is greater freedom of choice for the location of the label. In fact, the sheet intended to constitute the packaging for the product is, at this time, developed flat in the form of a continuous strip. As it is moving relative to the setting member, a simple adjustment of the respective drive parameters is sufficient.
Dans le cas particulier de l'étui de mouchoirs en papier, dont le rabat est formé par une partie de l'enveloppe elle-même, convenable¬ ment prédécoupée, la ligne de perforations est réalisée sur la bande de matériau souple avant sa transformation en étuis. Or, les prédé¬ coupes sont autant de lignes de faiblesse susceptibles de céder sous l'action des diverses tensions qui s'exercent sur la bande souple dans son passage à travers la machine. Grâce aux étiquettes chevau chant les lignes de perforation, les risques de déchirure, voire d rupture de la bande sont de ce fait nettement réduits. Cet avantage bien entendu, est valable dans la mesure seulement où celles-ci son appliquées immédiatement en aval de l'endroit où l'on réalise le prédécoupes. A la limite, cette disposition des organes autorise l réalisation d'une découpe continue du rabat.In the particular case of the tissue case, the flap of which is formed by a part of the envelope itself, suitably precut, the line of perforations is made on the strip of flexible material before it is transformed into cases. However, the pre-cuts are as many lines of weakness liable to give way under the action of the various tensions exerted on the flexible strip. in its passage through the machine. Thanks to the labels overlapping the perforation lines, the risks of tearing or even breakage of the strip are therefore considerably reduced. This advantage of course is valid only insofar as these are applied immediately downstream of the place where the precuts are made. Ultimately, this arrangement of the bodies allows the realization of a continuous cutting of the flap.
L'invention vise un dispositif permettant de réaliser ces étuis ave étiquettes. Il comporte un moyen pour entraîner une bande de matièr souple, la découper en feuilles et envelopper les produits avec celles ci et est caractérisé en ce qu'il comporte un organe de coupe coopéran avec un moyen de transfert pour découper les étiquettes dans un ruba adhésivé sur une face et rapporter lesdites étiquettes sur la bande e mouvement.The invention relates to a device for making these cases with labels. It comprises a means for driving a strip of flexible material, cutting it into sheets and wrapping the products with these and is characterized in that it comprises a cooperating cutting member with a transfer means for cutting the labels in an adhesive tape on one side and attach the said labels to the movement strip.
Selon un mode préféré de l'invention le moyen de transfert est constitu par un cylindre tournant dont l'axe de rotation est perpendiculaire à l direction de défilement de la bande et en contact sans glissement avec elle.According to a preferred embodiment of the invention, the transfer means consists of a rotating cylinder whose axis of rotation is perpendicular to the direction of travel of the strip and in contact without sliding with it.
La description qui suit se rapporte à un mode de réalisation non limi¬ tatif de l'invention.The description which follows relates to a nonlimiting embodiment of the invention.
La figure 1 est un schéma simplifié d'une ligne de production.Figure 1 is a simplified diagram of a production line.
La figure 2 représente en détail le poste de pose des étiquettes.Figure 2 shows in detail the labeling station.
On a représenté schématiquement sur la figure 1 une installation d'em¬ ballage de paquets de mouchoirs en ouate de cellulose. Ces paquets for¬ més de 8 ou 10 mouchoirs proviennent d'un poste amont par rapport à la direction des flèches, non représenté, où la ouate de cellulose a été transformée, c'est-à-dire pliée et découpée, et où les mouchoirs ont été empilés par paquets (2). Ils sont conduits par un transporteur à bande vers le poste (4), représenté suymboliquement par un bloc, pour être emballés dans un étui. Le poste (4) est également alimenté en feuilles (3) devant constituer les étuis. A la sortie, les paquets de mouchoirs (5) enveloppés dans les feuilles (3) sont dirigés au moyen d'un trans¬ porteur à bande vers un autre poste pour y subir éventuellement d'autres transformations, ou bien pour être préparés pour le transport. Dans les installations connues par la Demanderesse, l'étiquette est apposée sur les paquets à leur sortie du poste (4) , avec les inconvé¬ nients dus au fait qu'il s'agit d'un produit mou.There is shown schematically in FIG. 1 an installation for packaging packets of tissues of cellulose wadding. These packets formed of 8 or 10 handkerchiefs come from an upstream post with respect to the direction of the arrows, not shown, where the cellulose wadding has been transformed, that is to say folded and cut, and where the handkerchiefs were stacked in bundles (2). They are led by a conveyor belt to the station (4), represented suymbolically by a block, to be packaged in a case. The station (4) is also supplied with sheets (3) which must constitute the cases. At the exit, the packages of handkerchiefs (5) wrapped in the sheets (3) are directed by means of a belt conveyor to another station to undergo further possible transformations, or else to be prepared for the transport. In installations known to the Applicant, the label is affixed to the packages as they leave the station (4), with the drawbacks due to the fact that it is a soft product.
On peut réaliser cette opération plus simplement et avec une grande fiabilité en déposant l'étiquette sur le film d'enveloppe, avant la con¬ fection des étuis.This operation can be carried out more simply and with great reliability by depositing the label on the envelope film, before the packaging of the cases.
La figure 2 représente plus en détail le poste (6) dans lequel est effectuée cette opération.Figure 2 shows in more detail the station (6) in which this operation is carried out.
Une bande (11) d'un matériau plastique tel que le polyéthylene, ou bien en papier, est fournie à partir d'une bobine montée à rotation sur un axe (10) . La bande est maintenue tendue, au cours de son défilement à une vitesse linéaire VI, au moyen d'un bras oscillant (12).A strip (11) of a plastic material such as polyethylene, or else of paper, is supplied from a reel rotatably mounted on an axis (10). The strip is kept taut, during its running at a linear speed VI, by means of an oscillating arm (12).
Elle est guidée par divers cylindres de renvoi (13) jusqu'à un dispo¬ sitif de prédécoupe (14) des rabats. Celui-ci comprend deux cylindres (15, 16) montés à rotation sur des axes parallèles. L'un des cylindres (15) comporte une lame coupante (17) pourvue d'échancrures assurant une ligne de coupe discontinue, et dont la forme correspond à celle de la prédécoupe désirée. Cette dernière est réalisée sur la bande, au passage de la lame (17), par l'intervalle de pincement des deux cylindres.It is guided by various return cylinders (13) to a pre-cutting device (14) of the flaps. This comprises two cylinders (15, 16) mounted for rotation on parallel axes. One of the cylinders (15) comprises a cutting blade (17) provided with notches ensuring a discontinuous cutting line, and the shape of which corresponds to that of the desired precut. The latter is produced on the strip, at the passage of the blade (17), by the nip interval of the two cylinders.
Une bobine de ruban en plastique ou en papier (21) , adhésivé sur une face, est montée à rotation sur l'axe (22). Le ruban (21) est entraîné à une vitesse linéaire V2 inférieure à VI par les cylindres moteurs (24) dont les axes de rotation sont parallèles.A reel of plastic or paper tape (21), adhesive on one side, is rotatably mounted on the axis (22). The ribbon (21) is driven at a linear speed V2 lower than VI by the driving cylinders (24) whose axes of rotation are parallel.
Conformément à l'invention, on a disposé, en aval des cylindres (24) par rapport au sens de défilement du ruban (21) , un dispositif de coupe et de transfert (25). Il est constitué de deux cylindres (26, 28) entraînés en rotation dans des sens opposés autour d'axes parallèles aux cylindres moteurs. En particulier, le cylindre de transfert 28 est disposé et est entraîné de telle sorte qu'il roule sans glissement sur la bande (11). Sa vitesse linéaire est VI.According to the invention, there is arranged, downstream of the cylinders (24) relative to the direction of travel of the ribbon (21), a cutting and transfer device (25). It consists of two cylinders (26, 28) rotated in opposite directions around axes parallel to the driving cylinders. In particular, the transfer cylinder 28 is arranged and is driven so that it rolls without slipping on the strip (11). Its linear speed is VI.
Le cylindre (26) tourne à une vitesse synchronisée avec celle des cylindres moteurs (24) et comporte, en surface, des lames coupantes (27) orientées parallèlement à sa génératrice, venant à chaque rotation prendre appui sur la surface du cylindre adjacent (28) . Elles coopèrent avec le cylindre (28) aspirant pour découper les étiquettes dans l ruban qui est introduit dans leur intervalle. La surface du cylindr (28) est percée d'orifices communiquant avec une zone sous vide, e retient les étiquettes après leur découpe. Il est à noter que le ruba est présenté face non adhésivée sur le cylindre 28.The cylinder (26) rotates at a speed synchronized with that of the driving cylinders (24) and comprises, on the surface, cutting blades (27) oriented parallel to its generatrix, coming at each rotation to bear on the surface of the adjacent cylinder (28 ). They cooperate with the suction cylinder (28) for cutting the labels from the ribbon which is inserted in their interval. The surface of the cylinder (28) is pierced with orifices communicating with a vacuum zone, and retains the labels after they have been cut. It should be noted that the ruba is presented face non-adhesive on the cylinder 28.
Un troisième cylindre (30) , à la verticale des deux premiers (26 e 28) , tournant en sens opposé par rapport au cylindre (28) , comporte de éléments (31), formant enclumes, qui viennent, à chaque rotation, e appui sur le cylindre (28) .A third cylinder (30), vertical to the first two (26 e 28), rotating in opposite direction with respect to the cylinder (28), comprises elements (31), forming anvils, which come, at each rotation, e support on the cylinder (28).
Dans la zone d'appui des deux cylindres (28, 30), pour faciliter l transfert des étiquettes au moment où elles passent dans cette position, la communication de la surface du cylindre (28) avec le vide est inter rompue par une chicane non représentée, ou par un autre moyen interne.In the support zone of the two cylinders (28, 30), to facilitate the transfer of the labels when they pass in this position, the communication of the surface of the cylinder (28) with the vacuum is interrupted by a baffle not represented, or by some other internal means.
La bande provenant du dispositif de prédécoupe passe dans l'intervall de pincement des cylindres (28 et 30), y reçoit les étiquettes, et es acheminée vers le poste de confection des étuis (4) , par les cylindre de renvoi (33) •The strip coming from the precut device passes through the nip between the cylinders (28 and 30), receives the labels there, and is conveyed towards the case-making station (4), by the return cylinders (33) •
Dans l'exemple représenté, le poste d'emballage comporte un disque d grand diamètre (40) , dans lequel on a ménagé des alvéoles (4l) parallè¬ les à son axe pour recevoir individuellement les feuilles (3) • Celles-c sont obtenues par le dispositif ( 42) qui assure à la fois la découpe de la bande et la distribution dans les alvéoles. Après rotation du disque, d'un certain angle, les paquets de mouchoirs sont introduits à leur tour dans les emplacements occupés par les feuilles pour y être emballés. Bien que le fonctionnement apparaisse clairement à la lecture de ce qui précède, on le résume brièvement ci-après.In the example shown, the packing station includes a large diameter disc (40), in which cells (4l) have been arranged parallel to its axis to receive the sheets individually (3) • These are obtained by the device (42) which ensures both the cutting of the strip and the distribution in the cells. After rotation of the disc, from a certain angle, the packs of tissues are introduced in their turn into the locations occupied by the sheets to be wrapped there. Although the operation appears clearly on reading the above, it is briefly summarized below.
La bande (11) est déroulée depuis sa bobine d'alimentation, elle est guidée jusqu'au dispositif (14) où la lame (17) lui imprime, à interval¬ les réguliers, une ligne de perforations (lia). Le levier oscillant (12) permet de régler la bande à une tension suffisante pour éviter les plis ou les relâchements.The strip (11) is unwound from its supply reel, it is guided to the device (14) where the blade (17) prints, at regular intervals, a line of perforations (lia). The oscillating lever (12) allows the belt to be adjusted to a sufficient tension to avoid creases or slackening.
Ensuite, la bande parvient au niveau des cylindres (26, 28, 30) pour recevoir les étiquettes (11b) de la façon suivante : Le ruban (21) est guidé à la vitesse V2 par les rouleaux (24) en direc¬ tion du cylindre de transfert (28) qui tourne à la vitesse VI. La face non adhésivée du ruban est maintenue en contact glissant avec celui-ci grâce à la différence de pression qui règne de part et d'autre de la paroi du cylindre. Quand le ruban a été engagé d'une longueur déter¬ minée, la lame coupante (27) vient en position dans l'intervalle de pincement entre les cylindres (26 et 28) et pénètre dans le ruban dont il découpe une étiquette (11b) . Celle-ci poursuit alors son déplacement à la vitesse VI jusqu'à venir au contact de la bande 11, par sa face adhésivée contre lequel il est pressé.Then, the strip reaches the level of the cylinders (26, 28, 30) to receive the labels (11b) in the following manner: The ribbon (21) is guided at speed V2 by the rollers (24) in direction of the transfer cylinder (28) which rotates at speed VI. The non-adhesive side of the ribbon is kept in sliding contact with the latter thanks to the pressure difference which prevails on either side of the cylinder wall. When the ribbon has been engaged with a determined length, the cutting blade (27) comes into position in the nip between the cylinders (26 and 28) and enters the ribbon of which it cuts a label (11b) . The latter then continues its movement at speed VI until it comes into contact with the strip 11, by its adhesive-coated face against which it is pressed.
Quand la face adhésivée de l'étiquette vient au contact du film (11) la dépression, à laquelle est soumise sa face opposée, est interrompue afin de permettre le transfert sur le film. La rotation du contre-rouleau (30) est synchronisée avec l'avance des étiquettes de sorte que les enclumes (31) servent de surface d'appui.When the adhesive-coated face of the label comes into contact with the film (11), the depression, to which its opposite face is subjected, is interrupted in order to allow transfer to the film. The rotation of the counter-roller (30) is synchronized with the advance of the labels so that the anvils (31) serve as a bearing surface.
Il appartient au technicien de disposer les différents éléments les uns par rapport aux autres, et de synchroniser les mouvements de rotation des cylindres de telle sorte que les étiquettes viennent se placer à l'endroit souhaité, par rapport à la prédécoupe (lia), comme cela est représenté sur la figure.It is up to the technician to arrange the various elements with respect to each other, and to synchronize the rotational movements of the cylinders so that the labels are placed at the desired location, with respect to the precut (lia), as this is shown in the figure.
La bande est ensuite guidée vers le poste (42) où elle est séparée en feuilles- individuelles qui sont introduites une à une dans les alvéoles (4l) pour recevoir les paquets de mouchoirs. L'étui est ensuite formé autour du paquet par un rabattement approprié des bords de la feuille et leur scellage.The strip is then guided to the station (42) where it is separated into individual sheets which are introduced one by one into the cells (41) to receive the packs of tissues. The case is then formed around the package by an appropriate folding of the edges of the sheet and their sealing.
La description qui précède se rapporte à la pose de languettes adhési- vées sur des étuis de mouchoirs en papier. Le procédé est bien entendu applicable chaque fois qu'un produit doit être enveloppé dans une feuille en un matériau souple, qu'il s'agisse d'une languette adhésivée formant attache ou bien d'une simple étiquette. The foregoing description relates to the application of adhesive strips to tissue boxes. The method is of course applicable whenever a product must be wrapped in a sheet of flexible material, whether it is an adhesive tab forming a fastener or even a simple label.
