Abstract

The procedure, in which the articles (2) are carried along on two separate conveyors (B, C) and formed into groups by two adhesive strips (3) fed from reels on opposite sides, uses rollers (23) to apply the strips to the moving articles. The rollers are mounted on power cylinders (27) which bring the strips together between the groups of articles as one of the conveyors (B) is halted, while blades (24) cut through the strips to separate one group from the next. Brushes (35) on the same power cylinders (33) as the blades then apply the free ends of the cut strips to the rear end of the first group of articles.

Description

L'invention est relative à un procédé et à une installation pour réunir en lots des articles alignés, au moyen de tronçons de bandes adhésives avec rabats.The invention relates to a method and an installation for combine aligned items in batches using strip sections adhesive with flaps.

Actuellement pour réaliser des lots de plusieurs articles, tels que bouteilles ou boites, les articles sont disposés en une file continue sur un convoyeur amont les amenant à des moyens espaçant deux, trois ou quatre articles du reste de la file pour former un lot, puis ce lot est amené, par un convoyeur aval, à un poste de réunion des articles, où des moyens appliquent sur ceux-ci deux tronçons de bandes adhésives. Chaque tronçon s'étend entre une extrémité avant, rabattue contre la partie avant du premier article du lot, et une extrémité arrière, rabattue contre la partie arrière du dernier article de ce lot.Currently to carry out batches of several articles, such as bottles or boxes, the items are arranged in a continuous line on a upstream conveyor bringing them to means spacing two, three or four items from the rest of the queue to form a batch, then this batch is brought, by a downstream conveyor, to a post of assembly of the articles, where means apply two sections of adhesive tape to them. Each section extends between a front end, folded against the front part of the first article of the batch, and a rear end, folded against the part back of the last item in this batch.

La plupart des dispositifs actuels mettent en application les moyens décrits dans FR-A-1 474 009, et DE 4 120 480, c'est-à-dire comportant, en complément des convoyeurs précités :

  • des moyens qui, disposés de part et d'autre de la trajectoire de déplacement des articles, délivrent chacun une bande adhésive se dévidant d'une bobine, et comportent chacun, d'une part, un rouleau de renvoi et de placage de la bande correspondante contre l'une des faces longitudinales des lots, et, d'autre part, un couteau de sectionnement de la bande dans l'intervalle entre deux lots, ce couteau étant muni de moyens de rabattement des extrémités des bandes sur les lots,
  • un ensemble de contrôle et de commande de ces divers moyens,
  • et au moins un capteur détectant le passage des articles et réagissant sur l'ensemble de contrôle et de commande pour interrompre le mouvement du convoyeur aval et déclencher le mouvement des couteaux de sectionnement des bandes.
Most of the current devices apply the means described in FR-A-1 474 009, and DE 4 120 480, that is to say comprising, in addition to the aforementioned conveyors:
  • means which, arranged on either side of the trajectory of movement of the articles, each deliver an adhesive tape unwinding from a reel, and each comprise, on the one hand, a roller for returning and plating the strip corresponding against one of the longitudinal faces of the batches, and, on the other hand, a strip cutting knife in the interval between two batches, this knife being provided with means for folding the ends of the strips onto the batches,
  • a set of control and command of these various means,
  • and at least one sensor detecting the passage of the articles and reacting on the control and command assembly to interrupt the movement of the downstream conveyor and trigger the movement of the strip cutting knives.

Dans ces conditions, lorsque des articles verticaux recoivent des bandes de liaison et lors du sectionnement de ces bandes, ils sont simplement en appui par leur base sur le convoyeur aval. Il en résulte que sous les efforts qu'ils reçoivent, ils peuvent basculer d'un côté ou de l'autre, d'une valeur plus ou moins forte, mais toujours suffisante pour modifier le positionnement vertical de l'une ou des deux bandes adhésives et, en conséquence, l'aspect esthétique du lot. De plus, si l'un des articles d'un lot n'est pas parfaitement plaqué contre les autres articles du même lot, la mise en place des bandes adhésives n'enlève pas ce défaut, de sorte que le lot final garde ce défaut, manque de rigidité et doit être rebuté, puisque hors du format de suremballage et inesthétique.Under these conditions, when vertical articles receive connecting strips and when sectioning these strips they are simply supported by their base on the downstream conveyor. It follows that under the efforts they receive, they can tilt to one side or the other, of a greater or lesser value, but still sufficient to modify the vertical positioning of one or both adhesive tapes and, consequently, the aesthetic appearance of the lot. In addition, if one of the articles of a lot is not perfectly pressed against the other articles of the same lot, the installation of the adhesive tapes does not remove this defect, so that the final batch retains this defect, lacks rigidity and must be rejected, since out of the overpack format and unsightly.

La présente invention a pour objet de fournir un procédé et une installation permettant de remédier à ces inconvénients.The object of the present invention is to provide a method and a installation making it possible to remedy these drawbacks.

Ce procédé comprend, comme les procédés connus :

  • une phase de mise en lot,
  • une phase de dépôt de deux bandes adhésives sur deux côtés longitudinaux opposés des articles d'un lot en déplacement,
  • une phase de sectionnement, dans chaque bande, du tronçon reliant les articles d'un lot, alors à l'arrêt,
  • une phase de rabattement sur les articles des extrémités sectionnées des tronçons et des bandes,
  • et une phase d'évacuation du lot obtenu.
This method includes, like the known methods:
  • a batching phase,
  • a phase of depositing two adhesive strips on two opposite longitudinal sides of the articles of a moving batch,
  • a sectioning phase, in each strip, of the section connecting the articles of a batch, then stopped,
  • a drawdown phase on the articles of the severed ends of the sections and of the strips,
  • and an evacuation phase of the batch obtained.

Selon l'invention, il consiste :

  • à déposer les bandes adhésives (3) sur deux côtés opposés des articles (2a, 2b) en défilement composant un premier lot (A), mais alors qu'ils sont encore en déplacement en file continue, entre deux convoyeurs successifs, respectivement, amont (B) et aval (C),
  • avant que le premier article (2c) du lot suivant vienne en contact avec les bandes adhésives (3), à arrêter temporairement le convoyeur amont (B) en laissant fonctionner le convoyeur aval (C) pour espacer le premier lot (A) du premier article (2c) du lot suivant,
  • et, quand l'intervalle (E) obtenu entre les deux lots atteint une longueur déterminée, à arrêter temporairement le convoyeur aval (C) et à commander, successivement et dans l'ordre, le déplacement de rouleaux (23) plaquant les deux bandes adhésives sur l'extrémité avant du premier article (2c) du lot suivant, puis le fonctionnement des moyens (24, 35) assurant le sectionnement des bandes adhésives (3) et le rabattement de leurs extrémités (4 et 5) sur les articles extrêmes (2b, 2c) des deux lots contigus.
According to the invention, it consists:
  • depositing the adhesive strips (3) on two opposite sides of the articles (2a, 2b) by scrolling forming a first batch (A), but while they are still moving in continuous file, between two successive conveyors, respectively, upstream (B) and downstream (C),
  • before the first article (2c) of the next batch comes into contact with the adhesive strips (3), temporarily stop the upstream conveyor (B) by leaving the downstream conveyor (C) to operate to space the first batch (A) from the first article (2c) of the following batch,
  • and, when the interval (E) obtained between the two batches reaches a determined length, temporarily stopping the downstream conveyor (C) and controlling, successively and in order, the displacement of rollers (23) pressing the two strips adhesive on the front end of the first article (2c) of the next batch, then the operation of the means (24, 35) ensuring the cutting of the adhesive strips (3) and the folding of their ends (4 and 5) on the extreme articles (2b, 2c) of the two contiguous lots.

Grâce à cela, lors de la mise en place des bandes adhésives sur les articles, ceux-ci sont poussés mécaniquement par les articles qui les suivent, de sorte qu'il n'est pas possible que des articles d'un lot soient espacés. La liaison par les bandes adhésives des articles formant le premier lot avec le premier article du lot suivant, améliore la stabilité des articles, évite les variations de positionnement vertical des bandes adhésives et améliore le sectionnement, puisque celui-ci s'effectue alors que chaque bande est parfaitement tenue par son adhérence sur les articles délimitant l'intervalle entre le lot et la file d'articles. Cela garantit la régularité du positionnement longitudinal des tronçons de bande adhésive sur les articles du lot et permet d'utiliser des bandes pré-imprimées requérant un découpage et un positionnement précis.Thanks to this, when placing the adhesive strips on the articles, these are pushed mechanically by the articles which follow, so it is not possible that items in a batch are spaced. The bonding by adhesive strips of the articles forming the first batch with the first article of the following batch, improves the stability of the articles, avoids variations in the vertical positioning of the adhesive strips and improves sectioning, since this is done while each strip is perfectly held by its adhesion on the delimiting articles the interval between the batch and the line of articles. This guarantees the regularity of the longitudinal positioning of the strips of adhesive tape on the articles of the batch and allows the use of pre-printed tapes requiring a cutting and precise positioning.

Dans son application à la mise en lot d'articles cylindriques, ce procédé consiste également, après la phase de mise en lot, par arrêt du convoyeur amont, à déplacer chacun des rouleaux de renvoi des bandes adhésives, depuis une position de renvoi, dans laquelle il renvoie cette bande sur une trajectoire tangente aux articles, à une position de placage dans laquelle ce rouleau sécante la trajectoire normale de la bande adhésive et pince celle-ci sur la partie avant du premier article du lot suivant, en attente dans le convoyeur amont, puis, après sectionnement de la bande, à ramener le rouleau à sa position initiale de renvoi.In its application to the batching of cylindrical articles, this process also consists, after the batching phase, by stopping the upstream conveyor, to move each of the belt return rollers adhesive, from a return position, in which it returns this strip on a tangent path to the articles, at a plating position in which this roll intersects the normal trajectory of the adhesive strip and clamp it on the front part of the first article of the next batch, in waiting in the upstream conveyor, then, after cutting the strip, at return the roller to its original return position.

Ainsi les rouleaux de renvoi assurent non seulement le renvoi des bandes adhésives en leur communiquant une trajectoire parallèle à celle de déplacement des articles et en les plaquant contre ces articles, mais aussi, avant le sectionnement, le plaquage de ces bandes sur la partie amont du premier article suivant un lot et le pinçage de ces bandes sur l'article, pour améliorer leur maintien pendant le sectionnement.So the return rollers not only ensure the return adhesive strips by communicating a trajectory parallel to that moving the items and pressing them against those items but also, before sectioning, the plating of these strips on the part upstream of the first article following a batch and the pinching of these bands on the article, to improve their retention during sectioning.

Dans son application à la mise en lot d'articles rectangulaires, ce procédé consiste, simultanément à l'arrêt du convoyeur amont, à déplacer chacun des rouleaux de renvoi des bandes adhésives entre une position de renvoi, dans laquelle ce rouleau renvoie la bande adhésive sur une trajectoire parallèle à celle des articles, et une position en retrait, dans laquelle la bande adhésive décrit une trajectoire qui, inclinée par rapport à celle de déplacement du lot, va en se rapprochant de celle-ci depuis le rouleau de renvoi jusqu'au dernier article du lot en cours de formation, puis, après arrêt du lot et avant actionnement des couteaux, à ramener chaque rouleau à sa position initiale de renvoi de la bande adhésive et de placage de celle-ci sur le premier article du lot suivant. In its application to the batching of rectangular items, this process consists of moving the upstream conveyor simultaneously each of the return rolls of the adhesive strips between a position of return, in which this roller returns the adhesive tape on a trajectory parallel to that of the articles, and a recessed position, in which the adhesive strip describes a trajectory which, inclined with respect to that of displacement of the batch, is approaching it from the return roller to the last item in the batch being formed, then, after stopping the batch and before actuating the knives, bring each roller to its initial position for returning the adhesive tape and plating of it on the first article of the following batch.

Le déplacement des rouleaux les éloignent transversalement des flancs des articles en attente, afin que les bandes adhésives, qui vont être tirées par l'avancement du lot sur le convoyeur aval, ne puissent venir en contact avec les flancs du premier article du lot suivant, alors au repos sur le convoyeur, amont arrêté. Dès que l'espacement du lot par rapport à l'article suivant en attente a atteint la valeur requise, le convoyeur aval est arrêté et, simultanément, les rouleaux reviennent à leur position initiale de renvoi en plaquant les bandes adhésives sur le premier article. Ce plaquage favorise le sectionnement des bandes, et permet alors de lier ces bandes avec le premier article, en préparant ainsi le cycle suivant.The displacement of the rollers moves them transversely from the sides of pending items, so that the adhesive strips, which are going to be driven by the progress of the batch on the downstream conveyor, cannot come in contact with the sides of the first article of the following batch, then at rest on the conveyor, upstream stopped. As soon as the spacing of the lot in relation to the next pending item has reached the required value, the downstream conveyor is stopped and simultaneously the rollers return to their original position of return by plating the adhesive strips on the first article. This tackle promotes the sectioning of the bands, and then makes it possible to link these bands with the first article, thus preparing the next cycle.

L'invention concerne également l'installation permettant d'assurer cette réunion en lot.The invention also relates to the installation allowing to ensure this meeting in batch.

Dans cette installation, les rouleaux de renvoi et les couteaux sont disposés sensiblement dans la zone de transition entre le convoyeur amont et le convoyeur aval, tandis que, d'une part, l'alimentation des moyens moteur du convoyeur amont est sous la dépendance, à travers l'ensemble de contrôle et de commande, d'un capteur coupant cette alimentation au passage du premier article d'un lot en formation sur le convoyeur aval, et que, d'autre part, chacun des rouleaux est porté par des moyens déplacables transversalement et dans les deux sens, à partir d'une position de renvoi, dans laquelle ce rouleau renvoie la bande adhésive sur une trajectoire parallèle à celle des articles en déplacement.In this installation, the deflection rollers and the knives are arranged substantially in the transition zone between the conveyor upstream and downstream conveyor, while, on the one hand, the supply of motor means of the upstream conveyor is dependent, through the control and command assembly, of a sensor cutting this feed to the passage of the first article of a batch in training on the downstream conveyor, and that, on the other hand, each of the rollers is carried by means movable transversely and in both directions, from a return position, in which this roller returns the adhesive tape to a trajectory parallel to that of moving articles.

Lors de l'arrêt des deux convoyeurs amont et aval, c'est-à-dire après formation de l'espace entre le lot en cours de formation et le premier article suivant, et avant sectionnement des bandes adhésives, les rouleaux assurant le renvoi des bandes adhésives sont déplacés en direction du premier article du lot suivant pour venir plaquer sur lui les bandes adhésives et pincer ces bandes, de manière à en favoriser le sectionnement par les couteaux.When stopping the two upstream and downstream conveyors, i.e. after formation of the space between the batch being formed and the first next article, and before cutting the adhesive tapes, the rolls ensuring the return of the adhesive tapes are moved towards the first item of the next batch to come and stick the adhesive tapes on it and pinch these strips, so as to favor the cutting by the knives.

    • Comme montré à la figure 1, la mise en lot A de plusieurs éléments cylindriques 2, tels que deux boítes cylindriques 2a, 2b, est réalisée par deux tronçons 3a de bandes adhésives 3, dont les extrémités, respectivement, avant 4 et arrière 5, sont rabattues sur les éléments extrêmes composant le lot A.As shown in Figure 1, lot A of multiple cylindrical elements 2, such as two cylindrical boxes 2a, 2b, is produced by two sections 3a of adhesive strips 3, the ends of which, respectively, front 4 and rear 5, are folded down on the elements extremes composing lot A.

    L'installation assurant cette mise en lot comprend, comme montré à la figure 2, un convoyeur amont B, un convoyeur aval C et, dans la zone de transition entre ces deux convoyeurs et de part et d'autre de la trajectoire de déplacement des articles cylindriques 2, deux sous-ensembles D, débitant des bandes adhésives 3.The installation ensuring this batching includes, as shown in Figure 2, an upstream conveyor B, a downstream conveyor C and, in the transition zone between these two conveyors and on either side of the displacement trajectory of the cylindrical articles 2, two sub-assemblies D, cutting adhesive tapes 3.

    Dans la forme d'exécution représentée le convoyeur amont d'alimentation B est composé d'un convoyeur longitudinal et horizontal 6, portant des rouleaux horizontaux et transversaux 7, montés libres en rotation, et de deux convoyeurs à bandes B1, B2, latéraux et verticaux. Chacun de ces convoyeurs à bandes est composé d'un rouleau moteur 8, d'un rouleau de renvoi 9 et d'une ou plusieurs bandes sans fin 10, circulant autour de ces rouleaux en formant une bande dans le plan horizontal. Les brins en vis-à-vis des bandes 10 sont parallèles et espacés de la valeur du diamètre des articles cylindriques devant être entraínés, dans le sens de la flèche 11. Chacun des moteurs 8a des rouleaux moteurs 8 est alimenté par un circuit électrique 12, sous le contrôle d'un ensemble de commande et de contrôle 13.In the embodiment shown the upstream conveyor feed B is composed of a longitudinal and horizontal conveyor 6, carrying horizontal and transverse rollers 7, mounted free in rotation, and two belt conveyors B1, B2, lateral and vertical. Each of these belt conveyors is composed of a motor roller 8, a deflection roller 9 and one or more endless belts 10, circulating around these rollers, forming a band in the horizontal plane. The strands opposite the bands 10 are parallel and spaced by the value of the diameter of the cylindrical articles to be driven, in the direction of the arrow 11. Each of the motors 8a of the motor rollers 8 is supplied by an electrical circuit 12, under the control of a control and control 13.

    Le convoyeur aval C, qui peut être du même type que le convoyeur B, est représenté ici comme étant un convoyeur à bande 14 dont le brin supérieur est horizontal et est dans le prolongement du convoyeur 6 à rouleaux 7. Cette bande décrit une trajectoire sans fin autour d'un rouleau moteur 15 et d'un rouleau de renvoi, non représenté. Le rouleau moteur 15 est entraíné par un moteur 16 dont l'alimentation est assuré par un circuit 17 allant au boítier de commande 13.The downstream conveyor C, which can be of the same type as the conveyor B, is shown here as a belt conveyor 14 whose upper strand is horizontal and is an extension of the conveyor 6 with rollers 7. This belt describes an endless trajectory around a drive roller 15 and a deflection roller, not shown. The motor roller 15 is driven by a motor 16 whose power is provided by a circuit 17 going to the control unit 13.

    Chacun des sous-ensembles D comporte un dévidoir 20, motorisé ou non, pour une bobine 22 de bande adhésive 3, un rouleau vertical de renvoi et de placage 23 et un couteau 24.Each of the subsets D comprises a reel 20, motorized or not, for a reel 22 of adhesive tape 3, a roller vertical return and plating 23 and a knife 24.

    Les figures 2 et 3 montrent que les rouleaux 23 et les couteaux 24 sont disposés en aval du convoyeur amont B et dans la zone de transition entre ce convoyeur B et le convoyeur aval C.Figures 2 and 3 show that the rollers 23 and the knives 24 are arranged downstream of the upstream conveyor B and in the area of transition between this conveyor B and the downstream conveyor C.

    Chaque rouleau de renvoi 23 est supporté par des moyens aptes à les déplacer transversalement et dans les deux sens entre, une position de renvoi, montrée à la figure 2, dans laquelle il permet à la bande 3 de tangenter les articles 2 en défilement, et une position de placage, montrée figures 3, 5 et 6, et dans laquelle ce rouleau sécante partiellement la trajectoire des récipients et vient en appui sur l'article 2c dépassant des convoyeurs amont B.Each deflection roller 23 is supported by suitable means to move them transversely and in both directions between, a position return, shown in Figure 2, in which it allows the strip 3 to tangent the articles 2 in scrolling, and a position of plating, shown Figures 3, 5 and 6, and in which this roller partially intersects the trajectory of the containers and comes to bear on article 2c protruding from upstream conveyors B.

    Plus précisément et comme montré à la figure 3, chacun des rouleaux 23 est monté libre en rotation autour d'un axe vertical dans une chape 25 ménagée à l'extrémité libre de la tige 26 d'un vérin pneumatique 27. Ce vérin est fixé sur un élément 28 du bâti de l'installation et est alimenté par un circuit pneumatique à travers une électrovanne 29 pilotée par le boítier de commande 13. Un support 30, portant le couteau 24, est également calé à l'extrémité de la tige 32 d'un vérin pneumatique 33, fixé sur l'élément 28 du bâti.More precisely and as shown in Figure 3, each of the rollers 23 is mounted free to rotate about a vertical axis in a yoke 25 formed at the free end of the rod 26 of a pneumatic cylinder 27. This cylinder is fixed to an element 28 of the installation frame and is powered by a pneumatic circuit through a solenoid valve 29 piloted by the control unit 13. A support 30, carrying the knife 24, is also fixed at the end of the rod 32 of a pneumatic cylinder 33, fixed on element 28 of the frame.

    Ce vérin pneumatique 33 est alimenté par un circuit pneumatique au moyen d'une électrovanne 34 qui, indépendante de celle 29, est reliée par un circuit électrique à l'ensemble de commande 13.This pneumatic cylinder 33 is supplied by a circuit pneumatic by means of a solenoid valve 34 which, independent of that 29, is connected by an electrical circuit to the control assembly 13.

    Le support 30 porte latéralement deux brosses 35 dont l'utilité sera précisé plus loin.The support 30 laterally carries two brushes 35 whose utility will be explained later.

    Enfin, cette installation comporte deux capteurs, respectivement amont 37 et aval 38, reliés chacun par un circuit approprié au boítier de commande 13. Ces capteurs sont fixés de manière réglable sur un support, non représenté, et sont destinés à détecter le passage du premier élément 2a d'un lot en cours de formation pour déclencher des fonctions qui vont maintenant être décrites. Finally, this installation includes two sensors, respectively upstream 37 and downstream 38, each connected by a circuit suitable for the housing command 13. These sensors are fixed in an adjustable manner on a support, not shown, and are intended to detect the passage of the first element 2a of a batch being formed to trigger functions that will now be described.

    Lorsque l'installation est en début de cycle, comme montré à la figure 3, les convoyeurs amont B et aval C sont en mouvement à la même vitesse. Les rouleaux de renvoi 23 sont en position de renvoi et les couteaux 24 sont en position reculée.When the installation is at the start of the cycle, as shown in Figure 3, the upstream B and downstream C conveyors are moving at the same speed. The return rollers 23 are in the return position and the knives 24 are in the retracted position.

    Les convoyeurs à bandes B1 et B2 déplacent les articles 2 en file continue dans le sens de la flèche 11 et tendent donc à chasser le premier article 2a sur le convoyeur aval C. Cet article 2a étant lié par adhérence aux extrémités 4 des rubans adhésifs 3, rabattus sur lui lors de la réalisation du lot précédent, son déplacement dans le sens de la flèche 11, figure 2, entraíne avec lui les bandes adhésives 3. Les rouleaux 23 plaquent ces bandes sur les différents éléments composant le lot et, par exemple, sur les articles 2a et 2b.Belt conveyors B1 and B2 move items 2 by file continues in the direction of arrow 11 and therefore tend to chase the first article 2a on the downstream conveyor C. This article 2a being linked by adhesion to the ends 4 of the adhesive tapes 3, folded over it when carrying out the previous batch, moving it in the direction of the arrow 11, Figure 2, carries with it the adhesive strips 3. The rollers 23 these strips are affixed to the various elements making up the batch and, by example, on articles 2a and 2b.

    Lorsque, comme montré figure 2, l'article 2a est détecté par le capteur amont 37, le boítier de commande 13 interrompt l'alimentation des moteurs 8a des convoyeurs à bandes B1 et B2. Le convoyeur aval C continuant à entraíner les articles 2a 2b formant un lot A, il se forme, entre ce lot et l'article 2c du lot suivant, et comme montré figure 4, un intervalle E favorisant la découpe ultérieure des deux rubans 3.When, as shown in Figure 2, article 2a is detected by the upstream sensor 37, the control unit 13 interrupts the supply of motors 8a of the belt conveyors B1 and B2. The downstream conveyor C continuing to train articles 2a 2b forming a lot A, it forms, between this lot and item 2c of the next lot, and as shown in figure 4, an interval E favoring the subsequent cutting of the two ribbons 3.

    La longueur de cet intervalle E est réglable et déterminé par la position longitudinale du capteur aval 38, puisque ce dernier coupe l'alimentation du moteur 16 d'entraínement du convoyeur aval C, lorsque passe devant lui le premier article 2a du lot A, comme montré à la figure 4.The length of this interval E is adjustable and determined by the longitudinal position of the downstream sensor 38, since the latter cuts the supply of the motor 16 for driving the downstream conveyor C, when passes before him the first article 2a of lot A, as shown in Figure 4.

    Le capteur 38 déclenche également, par l'électrovanne 29, l'alimentation des vérins 27 dans le sens de leur extension pour déplacer transversalement les rouleaux de renvoi 23 de leur position de renvoi à leur position de placage.The sensor 38 also triggers, by the solenoid valve 29, the supply of the jacks 27 in the direction of their extension to move transversely the return rollers 23 from their return position to their plating position.

    Ainsi les rouleaux 23 viennent, comme montré à la figure 5, plaquer et pincer les bandes adhésives 3 sur la partie avant de l'article 2c saillant des convoyeurs B1 et B2.Thus the rollers 23 come, as shown in FIG. 5, press and pinch the adhesive strips 3 on the front part of article 2c protruding from conveyors B1 and B2.

    Immédiatement après, le boítier 13 commande les électrovannes 34, afin qu'elles alimentent les vérins 33 dans le sens du déplacement transversal des couteaux 24 l'un vers l'autre. Dans une première phase, chaque couteau sectionne la bande 3 dans sa partie 3b qui est parfaitement positionnée par adhérence sur les articles 2b et 2c. Dans un second temps, et donc après obtention des tronçons 3a de bande adhésive, les brosses 35, portées par le support 30 de chaque couteau, rabattent et plaquent vers l'arrière les extrémités découpées 4 des bandes 3, contre la face avant de l'article 2c, et, vers l'avant, les extrémités postérieures 5 des tronçons de bandes 3a, liant les éléments du lot A, contre la partie arrière de l'article arrière 2b de ce lot (figure 6). A la fin de cette opération, l'ensemble de contrôle et de commande 13 commande le retour des rouleaux 23 et des couteaux 24 à leurs positions initiales, respectivement, de renvoi et d'attente, et un nouveau cycle recommence.Immediately after, the housing 13 controls the solenoid valves 34, so that they feed the jacks 33 in the direction of movement transverse of the knives 24 towards each other. In a first phase, each knife cuts the strip 3 in its part 3b which is perfectly positioned by adhesion on articles 2b and 2c. In a second time, and therefore after obtaining the sections 3a of adhesive tape, the brushes 35, carried by the support 30 of each knife, fold and flatten backwards the cut ends 4 of the strips 3, against the front face of article 2c, and, towards the front, the posterior ends 5 of the sections of strips 3a, linking the elements of lot A, against the rear part of the article rear 2b of this lot (Figure 6). At the end of this operation, all of control and command 13 controls the return of rollers 23 and knives 24 at their initial positions, respectively, returning and wait, and a new cycle begins again.

    On notera que, à la différence des procédés et installations actuels séparant les éléments d'un lot avant de les réunir par des bandes adhésives, le procédé et l'installation selon l'invention assurent cette séparation seulement après que les éléments du lot soient déjà réunis entre eux par les bandes adhésives, ce qui procurent de nombreux avantages.It will be noted that, unlike the processes and installations separating the elements of a lot before joining them by bands adhesives, the method and the installation according to the invention ensure this separation only after the elements of the batch have already been brought together them by the adhesive tapes, which provide many advantages.

    Le premier résulte de la certitude d'obtenir, dans chaque lot, des éléments en contact, et cela grâce au convoyeur amont B poussant, les uns contre les autres et de façon continue, les éléments composant la file d'articles, puisque ceux-ci sont progressivement poussés dans l'espèce de boucle formée par les deux bandes adhésives. Cette absence d'espace entre articles améliore la rigidité des lots obtenus, garantit le positionnement longitudinal des bandes et, en conséquence, la répétitivité de l'encombrement et de l'aspect esthétique des lots. Quant à la découpe des bandes au moyen d'un couteau agissant sur un tronçon tenu par ces deux bouts, l'installation permet d'obtenir des découpes franches, nettes et parfaitement positionnées.The first results from the certainty of obtaining, in each batch, elements in contact, thanks to the pushing upstream conveyor B, some against others and continuously, the elements making up the queue of articles, since these are progressively pushed into the kind of loop formed by the two adhesive strips. This lack of space between articles improves the rigidity of the batches obtained, guarantees the longitudinal positioning of the bands and, consequently, the repeatability size and aesthetic appearance of the lots. As for cutting bands by means of a knife acting on a section held by these two ends, the installation makes it possible to obtain frank, clean and perfectly positioned.

    La même installation peut aussi assurer la mise en lot d'articles rectangulaires 102a, 102b, 102c, ..., moyennant quelques adaptations de son ensemble de commande 13 et des sous phases de son procédé de base.The same installation can also ensure the batching of articles rectangular 102a, 102b, 102c, ..., with some adaptations of its control assembly 13 and sub-phases of its method of based.

    Dans cette application et comme montré figure 7, la mise en lot des articles 102a, 102b s'effectue aussi par arrêt du seul convoyeur amont B, et déplacement des articles sous le contrôle des capteurs 37 et 38, mais les rouleaux 23 sont déplacés différemment. En effet, le capteur amont 37, en même temps qu'il commande l'arrêt du convoyeur amont B, à travers l'ensemble de contrôle et de commande 13, commande aussi l'actionnement des électrovannes 29, dans le sens de la rétraction des vérins 27, afin d'amener les rouleaux de renvoi 23 de leur position normale de renvoi à une position de retrait. Dans celle-ci, et comme montré figure 7, les bandes adhésives 3 qui sont tirées par les articles du lot A', et éventuellement aidées par les dévidoirs motorisés 20, décrivent une trajectoire inclinée 3d qui va en se rapprochant de la trajectoire normale, donc des flancs des articles, en allant du rouleau 23 vers le flanc du dernier article 102 b du lot A'. Il en résulte que les bandes sont éloignées transversalement des flancs de l'article suivant 102c et ne risquent pas de se coller sur ces flancs pendant l'écartement des articles formant le lot A'. Dès que le premier article 102a du lot est détecté par le capteur aval 38, celui-ci commande, en plus de l'arrêt du convoyeur aval C et des dévidoirs 20, d'abord, les électrovannes 29, puis les électrovannes 34, dans le sens de l'extension des vérins 27 et 33. De ce fait, les rouleaux 23 reviennent à leur position initiale de renvoi et plaquent les bandes adhésives 3 sur les flancs de l'article 102c en attente (Fig. 8), avant l'opération de sectionnement par les couteaux 24 et l'opération de rabattement par les brosses 25.In this application and as shown in Figure 7, batching articles 102a, 102b are also carried out by stopping the only upstream conveyor B, and movement of the articles under the control of sensors 37 and 38, but the rollers 23 are moved differently. Indeed, the upstream sensor 37, at the same time as it controls the stopping of the upstream conveyor B, through the control and command assembly 13, also controls actuation of the solenoid valves 29, in the direction of retraction of the cylinders 27, in order to bring the return rollers 23 from their normal position of return to a withdrawal position. In this one, and as shown in figure 7, the adhesive strips 3 which are pulled by the articles of lot A ', and possibly assisted by motorized reels 20, describe a 3d inclined trajectory which is approaching the normal trajectory, so from the sides of the articles, going from the roll 23 to the side of the last article 102 b of lot A '. As a result, the strips are far apart transversely of the sides of the following article 102c and are not likely to sticking to these sides during the spacing of the articles forming the lot A '. As soon as the first article 102a of the batch is detected by the downstream sensor 38, in addition to stopping the downstream conveyor C and the reels 20, first, the solenoid valves 29, then the solenoid valves 34, in the direction of the extension of the jacks 27 and 33. As a result, the rollers 23 return to their original return position and press the adhesive strips 3 onto the sides of article 102c pending (Fig. 8), before the operation of sectioning by the knives 24 and the folding operation by the brushes 25.

    Le procédé et l'installation qui viennent d'être décrits peuvent également être appliqués à la mise en lot au moyen de bandes adhésives respectivement, supérieure et inférieure, moyennant une modification de la position angulaires des sous-ensembles D débitant les bandes adhésives.The process and the installation which have just been described can also be applied to batching using adhesive tapes respectively, upper and lower, subject to a modification of the angular position of the sub-assemblies D delivering the adhesive tapes.
