Description

L'invention concerne un dispositif distributeur de sacs individuels d'emballage.The invention relates to a device for dispensing individual packaging bags.

Un tel dispositif est destiné notamment mais non exclusivement à distribuer des sacs d'emballage au niveau des rayons ou des caisses de sortie d'un magasin, de façon à permettre aux clients d'emballer leurs achats.Such a device is intended in particular but not exclusively to distribute packaging bags at the shelves or checkout outlets of a store, so as to allow customers to pack their purchases.

Il distribue les sacs conditionnés selon une bande continue, qui est constituée par une succession d'ébauches de sacs séparés les uns des autres par une ligne de prédécoupe de la bande.It distributes the conditioned bags according to a continuous strip, which is constituted by a succession of blanks of bags separated from each other by a precut line of the strip.

On connait déjà des dispositifs distribuant des objets divers formés en continu (DE-A-2.906.301, CH-A-447.584, DE-A-2.937.312 et GB-A-2.028.771).There are already known devices for distributing various objects formed continuously (DE-A-2,906,301, CH-A-447,584, DE-A-2,937,312 and GB-A-2,028,771).

Ces dispositifs comprennent principalement deux trains de rouleaux, l'un dit d'entrée, l'autre dit de sortie, comprenant chacun deux rouleaux dont les axes respectifs de rotation sont parallèles entre eux et définissent deux plans parallèles et dont les génératrices en vis à vis sont, par l'intermédiaire de la bande qui passe entre les deux rouleaux de chaque train, en appui l'une contre l'autre.These devices mainly comprise two sets of rollers, one said to be input, the other said to output, each comprising two rollers whose respective axes of rotation are parallel to each other and define two parallel planes and whose generatrices face each other. screws are, by means of the strip which passes between the two rollers of each train, bearing one against the other.

La vitesse linéaire à la périphérie des rouleaux de sortie des sacs est supérieure à la vitesse linéaire à la périphérie des rouleaux d'entrée de la bande d'ébauches.The linear speed at the periphery of the bag exit rollers is greater than the linear speed at the periphery of the entry rolls of the blank strip.

De cette façon, lorsque la bande d'ébauches est engagée dans les deux trains de rouleaux, elle est étirée jusqu'à sa rupture le long d'une ligne de prédécoupé ce qui, au niveau du train de rouleaux de sortie, libère un des objets, ici un sac d'emballage.In this way, when the strip of blanks is engaged in the two roller trains, it is stretched until it breaks along a pre-cut line which, at the output roller train, releases one of the objects, here a packing bag.

De préférence, l'entrainement en rotation des deux trains de rouleaux se poursuit jusqu'à ce que, d'une part, au niveau du train de sortie, un sac soit libéré et, d'autre part, au niveau du train d'entrée, la bande d'ébauches est engagée pour la être prêté à la distribution d'un nouveau sac.Preferably, the rotational drive of the two roller trains continues until, on the one hand, at the output train, a bag is released and, on the other hand, at the train of entry, the band of blanks is engaged to be loaned to the distribution of a new bag.

Les deux trains de rouleaux peuvent être à l'aplomb l'un de l'autre, le train de rouleaux d'entrée de la bande d'ébauches étant situé au dessus du train de sortie des sacs de manière que l'extrémité de la bande d'ébauches soit guidée par gravité vers les rouleaux du train inférieur de sortie des sacs ainsi que éventuellement par des guides latéraux rigides.The two roller trains can be perpendicular to each other, the train of rolls of entry of the strip of blanks being located above the train of exit of the bags so that the end of the strip of blanks is guided by gravity to the rollers of the lower bag outlet train as well as possibly by rigid lateral guides.

Cette disposition ne supprime toutefois pas les risques de bourrage entre les deux trains de rouleaux.This arrangement does not however eliminate the risk of jamming between the two roller trains.

En outre, elle impose une distribution verticale des sacs, du haut vers le bas, ce qui ne permet pas une installation facile du dispositif par exemple au niveau des caisses de magasins.In addition, it requires a vertical distribution of the bags, from top to bottom, which does not allow easy installation of the device, for example at the level of store cases.

Un résultat visé par la présente invention est un tel dispositif distributeur de sacs qui est perfectionné de manière à éviter tout risque de bourrage de la bande d'ébauches entre les deux trains de rouleaux.A result targeted by the present invention is such a bag dispensing device which is improved so as to avoid any risk of jamming of the strip of blanks between the two roller trains.

Un autre résultat visé par la présente invention est un tel dispositif qui permet un approvisionnement en bande d'ébauches qui est facile.Another result aimed by the present invention is such a device which allows a supply of strip of blanks which is easy.

Encore un autre résultat visé par la présente invention est une mise en place aisée du dispositif au niveau des caisses d'un magasin.Yet another result targeted by the present invention is an easy installation of the device at the checkouts of a store.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre.Other objects and advantages of the present invention will become apparent from the following description.

A cet effet, l'invention a pour objet un dispositif de distribution de sacs individuels d'emballage qui comprend deux trains de rouleaux, respectivement d'entrée de la bande d'ébauches et de sortie d'un sac, avec pour chaque train, deux rouleaux dont les axes de rotation respectifs sont parallèles entre eux et dont les génératrices en vis à vis sont, par l'intermédiaire de la bande d'ébauches qui passe entre les dits rouleaux, en appui l'une contre l'autre, la vitesse linéaire à la périphérie des dits rouleaux du train d'entrée de la bande d'ébauches étant inférieure à celle à la périphérie des rouleaux du train de sortie des sacs, ce dispositif étant notamment caractérisé en ce qu'il comprend par ailleurs, entre les deux trains de rouleaux, dans l'alignement des zones d'appui des deux rouleaux de chaque train un couloir d'entrainement des ébauches qui est limité au moins d'un côté par des moyens d'entraînement consistant en au moins une courroie sans fin dont le brin en appui sur la bande d'ébauches défile dans la direction d'avancement de cette bande d'ébauches.To this end, the subject of the invention is a device for distributing individual packaging bags which comprises two trains of rollers, respectively for entering the strip of blanks and leaving a bag, with for each train, two rollers whose respective axes of rotation are mutually parallel and whose opposite generatrices are, by through the strip of blanks which passes between said rollers, pressing one against the other, the linear speed at the periphery of said rollers of the input train of the strip of blanks being lower than that at the periphery of the rollers of the bag outlet train, this device being in particular characterized in that it also comprises, between the two train trains, in the alignment of the bearing zones of the two rollers of each train, a corridor for driving blanks which is limited at least on one side by drive means consisting of at least one endless belt, the strand resting on the strip of blanks scrolls in the direction of advancement of this strip d 'sketches.

L'invention sera mieux comprise à l'aide de la description qui va suivre, faite à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement :

  • - figure 1 : une vue de côté illustrant une partie des perfectionnements du dispositif,
  • - figure 2 : deux demi-vues, une demi-vue gauche en coupe B-B et une demi-vue droite en coupe A-A du dispositif de la figure 1,
  • - figure 3 : une vue de côté illustrant une partie des perfectionnements du dispositif de distribution de sacs.
The invention will be better understood with the aid of the description which follows, given by way of nonlimiting example, with reference to the attached drawing which schematically represents:
  • - Figure 1: a side view illustrating part of the improvements of the device,
  • FIG. 2: two half-views, a left half-view in section BB and a right half-view in section AA of the device of FIG. 1,
  • - Figure 3: a side view illustrating part of the improvements of the bag distribution device.

En se référant à la figure 1, le dispositif selon l'invention distribue un sac 2, à partir d'une bande 3 d'ébauches 4.Referring to FIG. 1, the device according to the invention distributes a bag 2, from a strip 3 of blanks 4.

Les ébauches 4 de la bande 3 sont séparées les unes des autres par une ligne de prédécoupe 5, c'est à dire une zone de faiblesse de la bande 3 le long de laquelle celle-ci se déchire lorsqu'on la soumet à une tension longitudinale.The blanks 4 of the strip 3 are separated from each other by a precut line 5, that is to say a zone of weakness of the strip 3 along which the latter tears when subjected to a tension longitudinal.

Le dispositif 1 comprend en outre un train de rouleaux 6 d'entrée de la bande d'ébauches 3, et un train de rouleaux 7 de sortie des sacs 2 l'un à la suite des autres.The device 1 further comprises a train of rollers 6 for entering the strip of blanks 3, and a train of rollers 7 for leaving the bags 2 one after the other.

Le train de rouleaux 6 comprend deux rouleaux 8, 9,.dont les axes respectifs sont parallèles entre eux et dont les génératrices en vis à vis sont en appui l'une contre l'autre de part et d'autre de la bande d'ébauches 3.The train of rollers 6 comprises two rollers 8, 9, the respective axes of which are parallel to one another and whose generatrices facing each other bear against each other on either side of the strip of drafts 3.

Le train de rouleaux 7 de sortie des sacs 2 comprend également deux rouleaux 10, 11 dont les axes respectifs sont parallèles et dont leurs génératrices en vis à vis sont en appui l'une contre l'autre de part et d'autre de la bande d'ébauches 3 ou d'un sac 2.The train of rollers 7 for outputting the bags 2 also comprises two rollers 10, 11 whose respective axes are parallel and whose generatrices facing each other bear against each other on either side of the strip blanks 3 or a bag 2.

Les axes des rouleaux 8, 9 d'une part et 10, 11 d'autre part, définissent deux plans qui sont sensiblement parallèles et, de préférence, la distance entre ces plans et donc entre les deux trains de rouleaux 6, 7 est Inférieure à la longueur moyenne d'un sac 2 ou d'une ébauche 3.The axes of the rollers 8, 9 on the one hand and 10, 11 on the other hand, define two planes which are substantially parallel and, preferably, the distance between these planes and therefore between the two trains of rollers 6, 7 is less the average length of a bag 2 or a blank 3.

Les rouleaux des deux trains 6, 7 sont entrainés dans un mouvement de rotation tendant à faire défiler la bande 3 du train de rouleaux d'entrée 6 vers le train de rouleaux de sortie 7 et la vitesse à la périphérie des rouleaux 8, 9 du train de rouleaux d'entrée 6 est inférieure à la vitesse à la périphérie des rouleaux 10, 11 du train de sortie 7.The rollers of the two trains 6, 7 are driven in a rotational movement tending to move the strip 3 from the train of input rollers 6 to the train of output rollers 7 and the speed at the periphery of the rollers 8, 9 of the train of input rollers 6 is less than the speed at the periphery of the rollers 10, 11 of the output train 7.

De cette manière , lorsque la bande d'ébauches 3 est engagée à la fois entre les rouleaux des trains 6, 7, elle se tend et est étirée jusqu'à son déchirement le long de la ligne de prédécoupe 5 qui est située entre les deux trains de rouleaux 6, 7.In this way, when the strip of blanks 3 is engaged at the same time between the rollers of the trains 6, 7, it stretches and is stretched until it is torn along the pre-cut line 5 which is situated between the two roller trains 6, 7.

De préférence, après déchirement de la bande 3 le long de la ligne de prédécoupe 5, la rotation des rouleaux des trains 6, 7 continue jusqu'à ce que le sac 2 soit entièrement évacué du train de sortie 7, et durant ce temps, la nouvelle extrémité avant 12 de la bande d'ébauches 3 s'avance vers le train de rouleaux 7, en vue de la distribution d'un nouveau sac.Preferably, after tearing of the strip 3 along the pre-cut line 5, the rotation of the rollers of the trains 6, 7 continues until the bag 2 is completely evacuated from the output train 7, and during this time, the new front end 12 of the strip of blanks 3 advances towards the train of rollers 7, for the distribution of a new bag.

La déchirure de la bande 3 d'ébauches 4 est par exemple détectée par des moyens 22 de détection optique situés entre les deux trains de rouleaux 6 et 7 de préférence du côté du train de sortie 7.The tear in the strip 3 of blanks 4 is for example detected by optical detection means 22 located between the two roller trains 6 and 7 preferably on the side of the output train 7.

Selon les présents perfectionnements, le dispositif 1 présente entre les deux trains de rouleaux 6, 7 un couloir d'entrainement 13, situé dans l'alignement des zones d'appui des rouleaux de chaque train et orienté sensiblement perpendiculairement à chaque plan défini par les axes des rouleaux de chaque train 6, 7.According to the present improvements, the device 1 has between the two roller trains 6, 7 a drive passage 13, located in alignment with the bearing zones of the rollers of each train and oriented substantially perpendicular to each plane defined by the axes of the rollers of each train 6, 7.

Le couloir d'entrainement 13 est limité au moins sur l'un de ces côtés par au moins une courroie 14 sans fin dont le brin en appui sur les ébauches défile dans la direction d'entrainement de la bande 3, et, s'il n'y en a que d'un côté, de manière préférentielle, la ou les courroies 14 se trouvent du côté où l'extrémité 12 de la bande d'ébauches a tendance à se diriger après déchirure de la ligne de prédécoupe à ce niveau.The drive passage 13 is limited at least on one of these sides by at least one endless belt 14, the strand resting on the blanks scrolls in the drive direction of the strip 3, and, if there is only one side, preferably, the belt or belts 14 are on the side where the end 12 of the strip of blanks tends to move after tearing of the pre-cut line at this level .

Dans la figure, le couloir d'entrainement 13 est délimité sur ses deux côtés par une pluralité de courroies respectivement 14, 15 dont leur brin qui esten appui sur les ébauches entraîne en défilement dans la direction d'avance de la bande 3.In the figure, the drive corridor 13 is delimited on its two sides by a plurality of belts respectively 14, 15 whose strand which is in abutment on the blanks drives in movement in the direction of advance of the strip 3.

Les courroies 14, 15 sont des courroies sans fin et dans le cas du mode de réalisation représenté, elles sont renvoyées à chacune de leurs extrémités par les rouleaux des trains 6, 7 qui assurent par ailleurs leur entrainement en défilement.The belts 14, 15 are endless belts and in the case of the embodiment shown, they are returned to each of their ends by the rollers of the trains 6, 7 which moreover ensure their drive in running.

Ainsi, les courroies 14 sont renvoyées par les rouleaux 9, 11 et les courroies 15 par les rouleaux 8, 10.Thus, the belts 14 are returned by the rollers 9, 11 and the belts 15 by the rollers 8, 10.

Ainsi que le représente la figure 2, chaque rouleau 8, 9, 10, 11 présente une pluralité de gorges périphériques 16, une pour chaque courroie renvoyée, les gorges étant placées à des distances définies.As shown in Figure 2, each roller 8, 9, 10, 11 has a plurality of peripheral grooves 16, one for each belt returned, the grooves being placed at defined distances.

Les gorges des rouleaux des trains d'entrée et de sortie ont une profondeur déterminée de manière à avoir à fond de gorge une même vitesse circonférentielle compte tenu de ce que les rouleaux des trains d'entrée et de sortie ont à leur périphérie des vitesses circonférentielles différentes.The grooves of the rollers of the input and output trains have a determined depth so as to have the same circumferential speed at the bottom of the groove, taking into account that the rollers of the input and output trains have circumferential speeds at their periphery different.

De préférence, pour avoir à leur périphérie une vitesse circonférentielle différente, au lieu que les rouleaux 8 à 11 des trains 6 et 7 soient de même diamètre et entrainés à une vitesse angulaire supérieure, ils sont entraînés à la même vitesse angulaire et le diamètre des rouleaux 10 et 11 du train de sortie 8 est supérieur au diamètre des rouleaux 8 et 9 du train d'entrée 7.Preferably, to have a different circumferential speed at their periphery, instead of the rollers 8 to 11 of the trains 6 and 7 being of the same diameter and driven at a higher angular speed, they are driven at the same angular speed and the diameter of the rollers 10 and 11 of the output train 8 is greater than the diameter of the rollers 8 and 9 of the input train 7.

Dans ce cas, pour assurer à fond de gorge une vitesse circonférentielle identique, il suffit que les gorges 16 de l'ensemble des rouleaux 8 à 11 présentent en fond de gorge, un diamètre sensiblement égal.In this case, to ensure an identical circumferential speed at the bottom of the groove, it suffices that the grooves 16 of all of the rollers 8 to 11 have, at the bottom of the groove, a substantially equal diameter.

Les gorges y seront donc en fait plus profondes que sur les rouleaux d'entrée.The grooves will therefore in fact be deeper there than on the input rollers.

Ce diamètre est au plus égal au diamètre des rouleaux 8, 9 du train 6 d'entrée de la bande 3 et, de préférence, il est au plus égal à ce même diamètre diminué de deux fois l'épaisseur des courroies.This diameter is at most equal to the diameter of the rollers 8, 9 of the input train 6 of the strip 3 and, preferably, it is at most equal to this same diameter reduced by twice the thickness of the belts.

La figure 2 représente les courroies 14 renvoyées par les rouleaux 9, 11 disposés en regard des courroies 15 renvoyées par les rouleaux 8, 10.FIG. 2 represents the belts 14 returned by the rollers 9, 11 arranged opposite the belts 15 returned by the rollers 8, 10.

Cette disposition n'est pas limitative et les courroies pourraient aussi bien être décalées latéralement les unes par rapport aux autres.This provision is not limiting and the belts could as well be offset laterally with respect to each other.

La disposition relative des trains de rouleaux 6 et 7 est variable et elle peut être telle que le couloir 13 défini par les courroies 14, 15 soit orienté horizontalement en oblique ou verticalement.The relative arrangement of the roller trains 6 and 7 is variable and it can be such that the passage 13 defined by the belts 14, 15 is oriented horizontally obliquely or vertically.

De préférence, cependant, dans le cas d'un couloir 13 oblique ou vertical , les rouleaux du train d'entrée 6 sont situés au dessus des rouleaux du train de sortie 7 de façon à profiter de la gravité.Preferably, however, in the case of an oblique or vertical corridor 13, the rollers of the input train 6 are located above the rollers of the output train 7 so as to take advantage of gravity.

Les courroies 14, 15 qui définissent le couloir d'entrainement 13 assurent un guidage dynamique de l'extrémité 12 de la bande 3 après déchirure jusqu'à son engagement entre les rouleaux 10, 11 du train de sortie 7, pour la distribution d'un nouveau sac. Les rouleaux 8, 9, 10, 11 des deux trains 6, 7 sont entrainés en rotation par tout moyen approprié, et de préférence, les rouleaux situés d'un même coté du couloir d'entrainement 13 par exemple les rouleaux 9, 11 sont moteurs c'est à dire qu'ils sont entrainés en rotation, par exemple à partir d'un moteur électrique et d'une transmission et les rouleaux 8, 10 situés de l'autre côté sont libres en rotation autour de leur axe.The belts 14, 15 which define the drive corridor 13 ensure dynamic guidance of the end 12 of the strip 3 after tearing until it engages between the rollers 10, 11 of the output train 7, for the distribution of a new bag. The rollers 8, 9, 10, 11 of the two trains 6, 7 are rotated by any suitable means, and preferably, the rollers located on the same side of the drive corridor 13 for example the rollers 9, 11 are motors ie they are driven in rotation, for example from an electric motor and a transmission and the rollers 8, 10 located on the other side are free to rotate about their axis.

Ils sont respectivement en appui contre les rouleaux 9, 11 éventuellement avec une pression d'appui réglable.They are respectively in abutment against the rollers 9, 11 possibly with an adjustable bearing pressure.

La commande de mise en rotation des rouleaux et de défilement des courroies 14 et 15 est par ailleurs réalisée par tout moyen approprié, un bouton, une pédale et de préférence, le mouvement des rouleaux 8 à 11 et des courroires 14, 15 dure jusqu'à ce que le sac 2 soit complétement évacué du train de sortie 7.The control for rotating the rollers and for running the belts 14 and 15 is moreover carried out by any suitable means, a button, a pedal and preferably the movement of the rollers 8 to 11 and of the belts 14, 15 lasts up to the bag 2 is completely evacuated from the output train 7.

En outre, de préférence, des dents ou une lame de dégagement 17 sont disposés juste en aval du train de rouleaux 7, à proximité immédiate de la périphérie d'au moins l'un des rouleaux du train 7, le rouleau 11 dans la figure 1 de façon à assurer le décollement du sac 2 distribué et son dégagement du train de sortie 7.In addition, preferably, teeth or a release blade 17 are arranged just downstream of the train of rollers 7, in the immediate vicinity of the periphery of at least one of the rollers of train 7, the roller 11 in the figure. 1 so as to ensure detachment of the bag 2 distributed and its disengagement from the outlet train 7.

Dans le cas de dents, leur extrémité pourra s'engager dans les gorges du rouleau du train de sortie de manière à s'insérer sous le sac et à l'obliger à s'écarter du dit rouleau.In the case of teeth, their end can engage in the grooves of the roller of the output train so as to fit under the bag and force it to move away from said roller.

Les gorges pourront être creusées spécialement pour les dents où ces dents pourront se placer dans les gorges entre ces dernières et la périphérie des rouleaux d'autant plus qu'au train de sortie, elles n'occupent généralement que le fond des dits gorges.The grooves can be hollowed out specially for the teeth where these teeth can be placed in the grooves between the latter and the periphery of the rollers all the more since in the output train, they generally only occupy the bottom of said grooves.

En se référant à la figure 3, dans un mode préférentiel de réalisation, les rouleaux 9, 11 situés d'un même coté par rapport au couloir d'entraînement 13 sont reliés à un bâti 18 fixe.Referring to Figure 3, in a preferred embodiment, the rollers 9, 11 located on the same side with respect to the drive corridor 13 are connected to a fixed frame 18.

Les rouleaux 8, 10 qui sont situés de l'autre côté du couloir d'entrainement 13 sont reliés à un chassis mobile 19 articulé par rapport au bâti 18, par exemple autour d'un axe 21 parallèle à l'axe des différents rouleaux.The rollers 8, 10 which are located on the other side of the drive corridor 13 are connected to a movable frame 19 articulated relative to the frame 18, for example around an axis 21 parallel to the axis of the various rollers.

Ceci n'est pas limitatif de l'invention, et par exemple l'axe 21 d'articulation pourrait également être orienté perpendiculairement à l'axe des différents rouleaux et parallèlement à la direction définie par le couloir 13.This is not limitative of the invention, and for example the hinge pin 21 could also be oriented perpendicular to the axis of the different rollers and parallel to the direction defined by the passage 13.

Dans la figure 3, l'ensemble des rouleaux est situé du même coté par rapport à l'axe 21, de façon à pouvoir écarter l'une de l'autre les deux parois qui délimitent fictivement le couloir d'entrainement 13.In FIG. 3, the set of rollers is located on the same side with respect to the axis 21, so as to be able to separate the two walls from one another which fictitiously delimit the drive corridor 13.

A titre d'illustration, on a représenté en traits mixtes le chassis 19 des rouleaux 8, 10 en position relevée.By way of illustration, the chassis 19 of the rollers 8, 10 is shown in dashed lines in the raised position.

Dans cette position,un opérateur a un accès très facile à la zone de passage de la bande 13 entre les rouleaux des trains. Ceci permet donc l'intervention rapide et facile en cas d'incident, ainsi qu'une introduction très facile d'une nouvelle bande 3 dans le dispositif.In this position, an operator has very easy access to the zone of passage of the strip 13 between the rollers of the trains. This therefore allows rapid and easy intervention in the event of an incident, as well as a very easy introduction of a new strip 3 into the device.

Eventuellement, des moyens appropriés assurent la liaison entre les axes des rouleaux 8, 10 et le chassis articulé 20 et ces moyens permettent de régler le parallélisme des rouleaux 8, 10 par rapport aux rouleaux 9, 11.Optionally, suitable means ensure the connection between the axes of the rollers 8, 10 and the articulated frame 20 and these means make it possible to adjust the parallelism of the rollers 8, 10 relative to the rollers 9, 11.

Ces moyens sont par exemple des vis de réglage pour les extrémités des axes des rouleaux 8, 10, éventuellement des extrémités de l'axe d'articulation 21.These means are for example adjustment screws for the ends of the axes of the rollers 8, 10, possibly the ends of the articulation axis 21.

Le chassis 20 peut être manoeuvré par un opérateur par tout moyen approprié, par exemple par une poignée de manoeuvre.The chassis 20 can be maneuvered by an operator by any appropriate means, for example by an operating handle.

Il peut présenter par ailleurs tout moyen approprié de rappel élastique qui tend à exercer une pression d'appui mutuel des deux rouleaux 8, 9 du train 6 et 10, 11 du train 7, cette pression pouvant être par ailleurs ajustable.It may also have any suitable elastic return means which tends to exert a pressure of mutual support of the two rollers 8, 9 of the train 6 and 10, 11 of the train 7, this pressure can also be adjustable.

Le fonctionnement du dispositif reste semblable à celui des dispositifs connus.The operation of the device remains similar to that of known devices.

Par une commande appropriée, notamment un bouton, une pédale ou tout autre moyen à disposition du caissier ou du client, la rotation des rouleaux des trains 6, 7 est commandée de même que le défilement des courroies 14, 15 du couloir d'entraînement 13. Cette rotation provoque la mise sous tension de la bande 3 d'ébauches 4, et sa déchirure le long d'une ligne de prédécoupe 5.By an appropriate command, in particular a button, a pedal or any other means available to the cashier or the customer, the rotation of the rollers of the trains 6, 7 is controlled as well as the running of the belts 14, 15 of the drive corridor 13 This rotation causes the strip 3 of blanks 4 to be tensioned, and to tear along a pre-cut line 5.

Cette coupure est par exemple détectée par des moyens optiques 22 situés entre les deux trains de rouleaux 6, 7.This cut is for example detected by optical means 22 located between the two trains of rollers 6, 7.

La détection de la coupure de la bande par les moyens optiques de détection 22 déclenche par exemple une temporisation qui maintient la rotation des rouleaux jusqu'à ce que le sac 2 soit complétement évacué du train de rouleaux de sortie 7 et que la nouvelle extrémité 12 de la bande 3 d'ébauches, guidée par les parois fictives du couloir d'entraînement 13, se présente entre les rouleaux 10, 11 du train 7, en vue de la distribution d'un nouveau sac.The detection of the cutting of the strip by the optical detection means 22 triggers for example a time delay which keeps the rotation of the rollers until the bag 2 is completely evacuated from the train of output rollers 7 and the new end 12 of the strip 3 of blanks, guided by the fictitious walls of the drive corridor 13, is presented between the rollers 10, 11 of the train 7, with a view to the distribution of a new bag.

Sur le circuit de commande, une mémoire pourra enregistrer le nombre de sacs demandés par exemple égal au nombre de pression sur le bouton poussoir puis délivrer sans s'arrêter autant de sacs que demandés.On the control circuit, a memory can record the number of bags requested, for example equal to the number of presses on the push button, then deliver without stopping as many bags as requested.

Naturellement, la présente description n'est donnée qu'à titre indicatif et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Naturally, the present description is given for information only and other implementations of the invention could be adopted without departing from the scope thereof.

En particulier, les moyens ·de renvoi des courroies 14, 15 pourraient être différents.In particular, the means · for returning the belts 14, 15 could be different.

Ils pourraient par exemple consister en des rouleaux de renvoi distincts des rouleaux 8 à 11 des trains 6, 7.They could for example consist of return rollers separate from the rollers 8 to 11 of the trains 6, 7.

Ils pourraient également consister en des poulies libres en rotation sur les axes des rouleaux 8 à 11 qui remplacent les gorges.They could also consist of free pulleys rotating on the axes of the rollers 8 to 11 which replace the grooves.

Dans ce cas, les rouleaux seraient constitués par une alternance de poulies libres et de bagues solidaires de l'axe.In this case, the rollers would be constituted by an alternation of free pulleys and rings integral with the axis.

De telles dispositions permettent d'entrafner les courroies 14, 15 à une vitesse de défilement indépendante de la vitesse de rotation des rouleaux 8 à 11 et notamment une vitesse de défilement comprise entre la vitesse à la périphérie des rouleaux 8, 9 et celle des rouleaux 10, 11.Such arrangements make it possible to entrain the belts 14, 15 at a running speed independent of the speed of rotation of the rollers 8 to 11 and in particular a running speed between the speed at the periphery of the rollers 8, 9 and that of the rollers 10, 11.

Egalement, des rouleaux auxiliaires pourraient être placés d'un côté du couloir 13 ou des deux côtés, de manière à détourner sensiblement les courroies 14 et/ou 15 et resserrer l'espace entre les côtés du couloir 13, c'est à dire des courroires 14 et 15.Also, auxiliary rollers could be placed on one side of the corridor 13 or on both sides, so as to substantially divert the belts 14 and / or 15 and tighten the space between the sides of the corridor 13, that is to say Courroires 14 and 15.
