Description

Procédé de fixation d'étiqueffes sur des emballages élémentaires en forme de sacs.Method of fixing labels on elementary packaging in the form of bags.

La présente invention se rapporte à un procédé pour fixer des étiquettes ou des bandes de papier sur les ouvertures d'emballages élémentaires en forme de sacs et susceptible d'être utilisé en particulier en combinaison avec des installations d'emballage entièrement automatiques. The present invention relates to a method for attaching labels or strips of paper to the openings of elementary packaging in the form of bags and which can be used in particular in combination with fully automatic packaging installations.

Une grande partie des marchandises vendues, par exemple dans les magasins appelés supermarchés est actuellement empaquetée séparément dans des emballages formés par des sacs de matière plastique. Bien que ce procédé d'emballage, à savoir le remplissage et la fermeture de ces emballages puisse être mis en ouvre rationnellement, depuis quelque temps, au moyen d'installations d'emballages automatiques et de matière d'emballage ou d'empaquetage appropriées pour cet usage, la fixation d'indicaions, par exemple de prix, sur chaque emballage terminé implique encore un travail considérable et long. La fixation de ces indications de prix sur ce type d'emballage doit encore en effet être exécutée à la main, en collant des bandes de papier portant le prix et présentant la forme d'étiquettes. Un autre inconvénient de ce mode de fixation des étiquettes de prix consiste dans le fait que ces emballages unitaires qui sont constitués par des sacs ne comportent pas de surfaces planes appropriées pour la fixation de l'étiquette et que, pour cette raison, la fixation manuelle ne sera pas, dans la plupart des cas, satisfaisante, l'étiquctte risquant fréquemment de se détacher lors de la manipulation de l'emballage. A large part of the goods sold, for example in stores called supermarkets, is currently packaged separately in packages formed by plastic bags. Although this packaging process, namely the filling and closing of such packages, can be implemented rationally, for some time, by means of automatic packaging installations and suitable wrapping or packaging material for This practice, the fixing of indications, for example of price, on each finished package still involves considerable and long work. The fixing of these price indications on this type of packaging must in fact still be carried out by hand, by gluing strips of paper bearing the price and in the form of labels. Another drawback of this method of fixing the price tags consists in the fact that these unit packages which are constituted by bags do not include suitable flat surfaces for fixing the label and that, for this reason, the manual fixing will not, in most cases, be satisfactory, as the label frequently may come off when handling the packaging.

Il existe d'autres difficultés qui ont trait à la fabrication d'étiquettes ayant une adhérence suffisante sur la surface de matière plastique.There are other difficulties which relate to making labels having sufficient adhesion to the plastic surface.

Le but de la présente invention est d'éliminer les inconvénients énumérés ci-dessus et de donner un moyen simple et sûr de fixation des étiquettes sur les emballages du type cité plus haut. Un autre avantage que l'on obtient consiste dans le fait que suivant l'invention, les étiquettes sont fixées de façon à être toujours situées au même endroit de l'emballage, à savoir à l'ouverture de l'emballage. The aim of the present invention is to eliminate the drawbacks enumerated above and to provide a simple and secure means of fixing labels on packaging of the type mentioned above. Another advantage which is obtained consists in the fact that according to the invention, the labels are fixed so as to always be located in the same place of the packaging, namely when the packaging is opened.

Suivant l'invention, on obtient ce résultat, ainsi que d'autres avantages par le fait que avant de fermer l'orifice du sac au moyen de rubans de fermeture connus en soi, l'étiquette est introduite et ajustée entre le ruban de fermeture et la face externe de la paroi du sac et, que, lors de la fermeture de l'orifice du sac, cette étiquette se trouve bloquée entre le ruban de fermeture et la paroi du sac. According to the invention, this result is obtained, as well as other advantages, by the fact that before closing the opening of the bag by means of closure tapes known per se, the label is introduced and adjusted between the closure tape and the outer face of the wall of the bag and that, when the opening of the bag is closed, this label is blocked between the closure tape and the wall of the bag.

Le procédé suivant l'invention peut avantageusement être mis en oeuvre dans des installations d'emballage à fonctionnement automatique dans le cas où l'on utilise la matière d'emballage sous la forme d'un tube comportant des logements d'emballage ou emballages élémentaires placés les uns à la suite des autres dans le sens de la longueur du tube et reliés entre eux d'une façon qui permet de les séparer, ce tube étant mû sur un support au moyen d'une bande transpurteuse sans fin, et les emballages élémentaires étant introduits un par un pour être ouverts, après quoi la denrée ou marchandise à emballer est introduite dans l'ouverture ainsi formée et les emballages remplis sont amenés un à un à un poste de fermeture situé dans le prolongement de la bande transporteuse; là ils sont séparés successivement du tube et fermés au moyen de rubans de fermeture susceptibles d'être tordus. The method according to the invention can advantageously be implemented in packaging installations with automatic operation in the case where the packaging material is used in the form of a tube comprising packaging housings or elementary packaging. placed one after the other in the direction of the length of the tube and connected together in a way which allows them to be separated, this tube being moved on a support by means of an endless transpurteuse belt, and the packaging elementary being introduced one by one to be opened, after which the food or merchandise to be packaged is introduced into the opening thus formed and the filled packages are brought one by one to a closing station located in the extension of the conveyor belt; there they are separated successively from the tube and closed by means of closing tapes capable of being twisted.

A ce stade, la bande ou étiquette portant le prix, qui est formée par exemple par une bande rectangulaire, peut être enfilée et ajustée entre le ruban de fermeture et la paroi du sac d'une façon continue à l'aide de moyens mécaniques appropriés connus en soi. At this stage, the strip or label bearing the price, which is formed for example by a rectangular strip, can be threaded and adjusted between the closure strip and the wall of the bag in a continuous fashion using suitable mechanical means. known per se.

D'autres avantages apparaîtront au cours de la description qui va suivre d'un mode de réalisation de l'invention. Other advantages will emerge from the following description of an embodiment of the invention.

Au dessin annexé, donné uniquement à titre d'exemple
La figure 1 représente un emballage élémentaire en forme de sac;
La figure 2 représente schématiquement un dispositif inclu dans un poste de fermeture, servant à fixer une étiquette.In the accompanying drawing, given by way of example only
FIG. 1 represents an elementary packaging in the form of a bag;
Figure 2 shows schematically a device included in a closing station, for attaching a label.

Sur le dessin, la référence 1 désigne un emballage unitaire formé par un sac dont l'ouverture 2 a été fermée au moyen d'un ruban de fermeture tordu 3. La figure 1 montre nettement une étiquette 4 portant une information et qui est placée entre le ruban de fermeture 3 et la paroi du sac à l'orifice 2 de ce sac. In the drawing, the reference 1 designates a unitary package formed by a bag whose opening 2 has been closed by means of a twisted closure tape 3. FIG. 1 clearly shows a label 4 bearing information and which is placed between the closure tape 3 and the wall of the bag at the opening 2 of this bag.

Sur la figure 2, on a représenté un dispositif approprié pour ajuster et enfiler les étiquettes au poste de fermeture entre la paroi du sac, à proximité de l'ouverture de ce dernier. et le ruban de fermeture. Les étiquettes sont approvisionnées sous la forme d'un ruban continu 5 qui se dévide d'une bobine de réserve (non représentée), au moyen de rouleaux d'entraînement 6, 7 en passant dans un dispositif 8 à cellule photo-électrique ou, suivant une variante, dans un mécanisme d'impression, et un dispositif de découpage 9 pour atteindre l'ori fice 2 d'un sac situé dans un poste de fermeture. In Figure 2, there is shown a suitable device for adjusting and threading the labels at the closing station between the wall of the bag, near the opening of the latter. and the closure tape. The labels are supplied in the form of a continuous tape 5 which unwinds from a reserve spool (not shown), by means of drive rollers 6, 7 passing through a device 8 with a photocell or, according to a variant, in a printing mechanism, and a cutting device 9 to reach the opening 2 of a bag located in a closing station.

Le poste de fermeture comprend deux éléments de fermeture 10, 11 qui sont situés de part et d'autre du col du sac, chacun de ces éléments est muni d'un évidement en V dont l'ouverture est dirigée vers le col du sac; ces évidements dont les bords convergent dans le sens opposé au col du sac, se prolonge par une fente de guidage étroite, 12 ou 13 respectivement. L'élément 10 est de préférence fixe tandis que l'élément il situé de l'autre côté du col du sac peut se rapprocher de l'élément 10 pour resserrer le col du sac.The closing station comprises two closing elements 10, 11 which are located on either side of the neck of the bag, each of these elements is provided with a V-shaped recess, the opening of which is directed towards the neck of the bag; these recesses, the edges of which converge in the direction opposite to the neck of the bag, is extended by a narrow guide slot, 12 or 13 respectively. The element 10 is preferably fixed while the element 11 located on the other side of the neck of the bag can approach the element 10 to tighten the neck of the bag.

Pour exécuter une opération de fermeture, on introduit l'extrémité ouverte du sac dans l'ouverture formée par les deux éléments 10 et il en position de repos; le ruban 5 est en meme temps introduit dans le poste de fermeture et est ajusté ou orienté à peu près parallèlement à la direction longitudinale du sac, entre le col de celui-ci et l'élément 11. En même temps que ce mouvement s'ef fectue, l'élément 11 coulisse sur l'élément 10 et ceci a pour effet de resserrer le col du sac en même temps que l'étiquette 4, qui est maintenant séparée du ruban 5 et serrée entre les fonds des fentes de guidage 12, 13.
ce moment, un ruban de fermeture se place autour du col du sac qui est resserré de cette fason dans la fente de guidage 12, sous l'action de doigts de pliage 14, 15 qui peuvent se déplacer en direction de la fente de guidage 12 et qui sont montés dans l'élément 10. Le ruban de fermeture 3 est découpé par des couteaux 16, 17, dans une bande continue 18. au moment du déplacement des doigts de pliage 14, 15, puis il est serré sur le col du sac et sur l'étiquette qui est disposée contre le col du sac; les deux extrémités de ce ruban viennent se placer entre des griffes de serrage 19 et 20 qui sont montées rotatives dans l'élément 11. Les griffes de serrage 19 et 20 sont ensuite entraînées en rotation sur 2,5 tours au moyen d'un dispositif non représenté sur le dessin, de sorte mulon obtient ainsi la torsion désirée du ruban de fermeture.To perform a closing operation, the open end of the bag is introduced into the opening formed by the two elements 10 and it in the rest position; the tape 5 is at the same time introduced into the closing station and is adjusted or oriented approximately parallel to the longitudinal direction of the bag, between the neck of the latter and the element 11. At the same time as this movement takes place. If done, the element 11 slides on the element 10 and this has the effect of tightening the neck of the bag at the same time as the label 4, which is now separated from the tape 5 and clamped between the bottoms of the guide slots 12 , 13.
At this moment, a closure tape is placed around the neck of the bag which is tightened in this way in the guide slot 12, under the action of folding fingers 14, 15 which can move in the direction of the guide slot 12 and which are mounted in the element 10. The closure tape 3 is cut by knives 16, 17, in a continuous strip 18. when the folding fingers 14, 15 move, then it is clamped on the neck of the bag and on the label which is placed against the neck of the bag; the two ends of this tape are placed between the clamping claws 19 and 20 which are rotatably mounted in the element 11. The clamping claws 19 and 20 are then driven in rotation over 2.5 turns by means of a device not shown in the drawing, so mulon thus obtains the desired twist of the closure tape.

L'élément 11 est ensuite ramené å sa position initiale et le sac ainsi fermé, qui est maintenant muni d'une étiquette peut être évacué du poste de fermeture.The element 11 is then returned to its initial position and the bag thus closed, which is now provided with a label, can be removed from the closing station.

On utilise de préférence comme ruban de fermeture des rubans de matière plastique renforces par des fils métalliques. Plastic tapes reinforced with metallic threads are preferably used as the closure tape.

Les étiquettes de prix peuvent être munies à l'avance du texte désiré ou bien le texte, par exemple le prix réel de la marchandise emballée, peut être inscrit par la suite. The price tags can be provided in advance with the desired text or the text, for example the actual price of the packaged goods, can be entered afterwards.

Le procédé suivant l'invention peut également être mis en oeuvre avec profit dans les installations d'emballage automatiques, par exemple lorsqu'on utilise un tube de matière d'emballage qui porte dans le sens longitudinal. des emballages élémentaires et fixés de façon détachable, constitués par des sacs dont chacun présente une fermeture infé rieure, Ce tube est introduit, d'une façon connue en soi, sur un support et les emballages élémentaires sont ouverts successivement par gonflage à l'air. La marchandise est ensuite introduite dans le sac et les emballages élémentaires remplis qui sont encore reliés entre eux sont amenés au moyen d'une bande transporteuse à un poste de fermeture qui agit essentiellement de la même façon que le dispositif décrit en regard de la figure 2. The method according to the invention can also be carried out with advantage in automatic packaging installations, for example when a tube of packaging material which bears in the longitudinal direction is used. elementary packages and detachably fixed, consisting of bags each of which has a lower closure, This tube is introduced, in a manner known per se, on a support and the elementary packages are successively opened by inflation with air . The goods are then introduced into the bag and the filled elementary packages which are still interconnected are brought by means of a conveyor belt to a closing station which acts essentially in the same way as the device described with reference to figure 2. .

Toutefois, dans ces installations, et en raison de l'introduction continue du tube formant les sacs dans le poste de fermeture, il est nécessaire d'approvisionner les étiquettes de prix sur un côté de l'emballage élémentaire et il est donc avantageux que les étiquettes de prix soient enfilées et ajustées entre les emballages élémentaires et la fente de guidage 12. de l'élément 10. Par ailleurs. il est possible de munir en continu les étiquettes de prix des indications désirées, d'une façon connue en soi, au moyen d'un dispositif d'impression agencé dans le poste de remplissage. However, in these installations, and due to the continuous introduction of the tube forming the bags into the closing station, it is necessary to supply the price tags on one side of the elementary packaging and it is therefore advantageous that the price tags are threaded and adjusted between the elementary packaging and the guide slot 12. of the element 10. Furthermore. it is possible to continuously provide the price tags with the desired indications, in a manner known per se, by means of a printing device arranged in the filling station.

Bien entendu l'invention n'est nullement limitée au mode de réalisation représenté et décrit qui n'a été choisi qu'à titre d'exemple. Of course, the invention is in no way limited to the embodiment shown and described which was chosen only by way of example.

FIG. 1 represents an elementary packaging in the form of a bag; Figure 2 shows schematically a device included in a closing station, for attaching a label. In the drawing, the reference 1 designates a unitary package formed by a bag whose opening 2 has been closed by means of a twisted closure tape 3. FIG. 1 clearly shows a label 4 bearing information and which is placed between the closure tape 3 and the wall of the bag at the opening 2 of this bag. In Figure 2, there is shown a suitable device for adjusting and threading the labels at the closing station between the wall of the bag, near the opening of the latter. and the closure tape. The labels are supplied in the form of a continuous tape 5 which unwinds from a reserve spool (not shown), by means of drive rollers 6, 7 passing through a device 8 with a photocell or, according to a variant, in a printing mechanism, and a cutting device 9 to reach the opening 2 of a bag located in a closing station.
