Description

L'invention concerne un procédé et un appareil d'insertion d'un moyen de fixation dans une plaque ou bande de matériau souple destinée à former un emballage.The invention relates to a method and an apparatus for inserting a fixing means into a plate or strip of flexible material intended to form a package.

Dans le domaine de l'emballage, il est connu de cercler ledit emballage, sous forme par exemple d'un cartonnage, avec un feuillard ou similaire comme par exemple une bande en matériau synthétique afin de fermer ou de consolider ledit emballage.In the field of packaging, it is known to encircle said packaging, for example in the form of cardboard, with a strip or the like, for example a strip of synthetic material in order to close or consolidate said packaging.

La difficulté de ce type de fixation ou consolidation résulte du fait qu'il faut maintenir l'emballage au moment de son cerclage et qu'il faut bien entendu manipuler à la fois l'emballage et son moyen de cerclage.The difficulty of this type of fixing or consolidation results from the fact that the packaging must be maintained at the time of its strapping and that it is of course necessary to handle both the packaging and its strapping means.

C'est pourquoi l'inventeur a imaginé un procédé et un appareil pour insérer un tel moyen de fixation dans une plaque ou bande de matériau souple destinée à former un emballage et qui est munie d'une gorge pourvue de deux lèvres qui ferment en partie ladite gorge et entre lesquelles ledit moyen de fixation doit être introduit.This is why the inventor has devised a method and an apparatus for inserting such a fixing means into a plate or strip of flexible material intended to form a package and which is provided with a groove provided with two lips which close in part. said groove and between which said fixing means must be introduced.

Le procédé selon l'invention est notamment remarquable en ce qu'il consiste à cambrer la plaque ou bande dans le sens transversal à la direction de sa gorge de manière à écarter ses lèvres, à introduire le moyen de fixation, à remettre sensiblement à plat ladite plaque ou bande afin que lesdites lèvres reprennent leurs positions initiales et à deplacer la plaque ou bande dans le sens longitudinal à sa gorge pendant les opérations de cambrage transversal et de remise à plat.The method according to the invention is particularly remarkable in that it consists in arching the plate or strip in the direction transverse to the direction of its throat so as to separate its lips, to introduce the fixing means, to put it substantially flat said plate or strip so that said lips return to their initial positions and to move the plate or strip in the longitudinal direction to its throat during the transverse bending and reshaping operations.

Selon un mode de réalisation, on déplace en outre la plaque ou bande dans le sens longitudinal à sa gorge pendant les opérations de cambrage transversal et de remise à plat, tandis que, par exemple, on guide la plaque ou bande préalablement à son cambrage par au moins un moyen introduit dans sa gorge.According to one embodiment, the plate or strip is further displaced in the longitudinal direction at its groove during the transverse bending and flattening operations, while, for example, the plate or strip is guided prior to its bending by at least one means introduced into his throat.

Avantageusement, on peut aussi maintenir en position dans le fond de la gorge l'élément de fixation en appuyant sur celui-ci pendant la remise à plat.Advantageously, one can also maintain in position in the bottom of the groove the fixing element by pressing on it during the flattening.

De préférence, on écrase les lèvres de la gorge après remise à plat de la plaque ou bande.Preferably, the lips of the throat are crushed after flattening of the plate or strip.

Le moyen de fixation utilisé se présente, par exemple, sous la forme d'un feuillard ou similaire, bien que ce moyen de fixation peut évidemment se présenter sous d'autres formes (câbles, ...)The fixing means used is, for example, in the form of a strip or the like, although this fixing means can obviously be presented in other forms (cables, etc.)

Pour la mise en oeuvre d'un tel procédé, l'invention propose aussi un appareil qui est notamment remarquable en ce qu'il comporte un moyen de cambrage transversal de la plaque ou bande, un moyen d'introduction de l'élément de fixation et un moyen de remise à plat de la plaque ou bande ainsi que des moyens pour entraîner la plaque ou bande dans le sens longitudinal à sa gorge.For the implementation of such a method, the invention also provides an apparatus which is particularly remarkable in that it comprises a means for transversely bending the plate or strip, a means for introducing the fixing element. and a means for flattening the plate or strip as well as means for driving the plate or strip in the longitudinal direction to its groove.

Un appareil avec les caractéristiques dans le préambule de la revendication 6 est décrit dans le document US-A-3 133 637.An apparatus with the features in the preamble of claim 6 is described in US-A-3,133,637.

Selon un mode de réalisation, le moyen de cambrage est constitué par deux roues superposées dont les jantes présentent respectivement une face concave et une face sensiblement convexe, la plaque ou bande étant destinée à passer entre lesdites roues, sa gorge étant tournée vers la roue à jante concave.According to one embodiment, the cambering means consists of two superimposed wheels whose rims respectively have a concave face and a substantially convex face, the plate or strip being intended to pass between said wheels, its groove being turned towards the wheel to concave rim.

Avantageusement dans ce cas, le moyen d'introduction de l'élément de fixation est constitué par une rampe de guidage pour l'alimentation dudit élément, l'extrémité de ladite rampe parvenant au voisinage des roues de cambrage et entre celles-ci, et par une nervure circulaire ménagée sur la roue concave afin que ladite nervure puisse appuyer sur l'élément de fixation pendant le cambrage.Advantageously in this case, the means for introducing the fastening element consists of a guide ramp for feeding said element, the end of said ramp reaching in the vicinity of the bending wheels and between them, and by a circular rib formed on the concave wheel so that said rib can press on the fixing element during bending.

De préférence, le moyen de remise à plat de la plaque ou bande comporte des ailes de redressement qui passent progressivement d'une position oblique vers une position sensiblement plane, tandis que l'appareil comporte en outre un moyen de maintien en position de l'élément de fixation aménagé au-dessus des ailes de redressement et qui se présente sous la forme d'une barrette.Preferably, the means for flattening the plate or strip comprises straightening wings which progressively pass from an oblique position to a substantially flat position, while the apparatus further comprises means for holding the position of the fastening element arranged above the straightening wings and which is in the form of a bar.

L'appareil peut aussi comporter un moyen initial de maintien et de guidage de la plaque ou bande, aménagé en amont du moyen de cambrage par rapport au sens de déplacement de la plaque ou bande et qui se présente sous la forme d'un cylindre sur lequel passe ladite plaque ou bande, et d'un galet prévu pour venir s'appuyer dans le fond de la gorge de ladite plaque ou bande. Entre le moyen initial de maintien et de guidage et le moyen de cambrage, on peut prévoir aussi un guide d'alignement sous forme d'une barrette.The apparatus may also include an initial means for holding and guiding the plate or strip, arranged upstream of the bending means with respect to the direction of movement of the plate or strip and which is in the form of a cylinder on which passes said plate or strip, and a roller provided to come to bear in the bottom of the groove of said plate or strip. Between the initial holding and guiding means and the bending means, an alignment guide can also be provided in the form of a bar.

Avantageusement, un moyen d'écrasement des lèvres de la gorge sous forme de cylindres de pression, est aménagé en aval du moyen de remise à plat.Advantageously, a means for crushing the lips of the throat in the form of pressure cylinders is arranged downstream of the flattening means.

Les moyens pour entraîner la plaque ou bande dans le sens longitudinal à sa gorge sont par exemple constitués au moins en partie par la motorisation d'au moins l'une des roues du moyen de cambrage et/ou du cylindre initial de maintien et de guidage et/ou d'au moins l'un des cylindres d'écrasement des lèvres de la gorge.The means for driving the plate or strip in the longitudinal direction at its groove are for example constituted at least in part by the motorization of at least one of the wheels of the bending means and / or of the initial cylinder for holding and guiding and / or at least one of the crushing cylinders of the lips of the throat.

Pour une un plaque ou bande, muni en outre d'un retour sensiblement d'équerre afin de former une cornière, l'appareil peut en outre être remarquable en ce que le cylindre du moyen initial de maintien et de guidage et l'un des cylindres du moyen d'écrasement comportent une gorge circulaire périphérique pour le passage du retour sensiblement d'équerre de la plaque ou bande.For a plate or strip, further provided with a substantially square return in order to form an angle iron, the apparatus can also be remarkable in that the cylinder of the initial means for holding and guiding and one of the crushing means cylinders have a peripheral circular groove for the passage of the substantially square return of the plate or strip.

L'invention sera bien comprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels :

  • la figure 1 montre une plaque ou bande dans laquelle a été inséré un feuillard au moyen d'un appareil selon l'invention,
  • la figure 2 est une perspective schématique d'un appareil selon l'invention,
  • la figure 3 est une coupe longitudinale de la figure 2 selon la flèche III avec en plus la plaque ou bande à équiper,
  • les figures 4 à 8 sont des coupes respectivement selon IV-IV, V-V, VI-VI, VII-VII, VIII- VIII de la figure 3.
The invention will be clearly understood on reading the description which follows and which refers to the appended drawings in which:
  • FIG. 1 shows a plate or strip into which a strip has been inserted by means of an apparatus according to the invention,
  • FIG. 2 is a schematic perspective of an apparatus according to the invention,
  • FIG. 3 is a longitudinal section of FIG. 2 according to arrow III with in addition the plate or strip to be fitted,
  • Figures 4 to 8 are sections respectively on IV-IV, VV, VI-VI, VII-VII, VIII-VIII of Figure 3.

Sur la figure 1, on peut voir une plaque ou bande 1 en matériau souple munie d'une gorge 2 formée ou comportant deux lèvres 2a et 2b qui ferment en partie ladite gorge 2 et dans laquelle un feuillard 3 ou similaire est inséré. La gorge 2 est disposée longitudinalement et de manière rectiligne.In Figure 1, we can see a plate or strip 1 of flexible material provided with a groove 2 formed or having two lips 2a and 2b which partially close said groove 2 and in which a strip 3 or the like is inserted. The groove 2 is arranged longitudinally and in a straight line.

Pour insérer ou sertir un tel feuillard, l'invention préconise donc de cambrer la plaque ou bande 1 transversalement par rapport à la direction de sa gorge 2, à insérer le feuillard 3 et à remettre à plat ladite plaque ou bande.To insert or crimp such a strip, the invention therefore recommends arching the plate or strip 1 transversely with respect to the direction of its groove 2, inserting the strip 3 and placing said plate or strip flat.

A cet effet, l'invention propose l'appareil représenté plus spécialement sur les figures 2 et 3, destiné à insérer en continu ledit élément de fixation selon le procédé rappelé ci-avant dont d'autres particularités apparaîtront suite à la description de l'appareil qui va suivre.To this end, the invention proposes the apparatus shown more particularly in FIGS. 2 and 3, intended for continuously inserting said fastening element according to the process recalled above, of which other particularities will appear following the description of the device that will follow.

L'appareil selon l'invention comporte un moyen initial de maintien et de guidage comportant un cylindre 4 ici motorisé comme il sera expliqué ci-après et un galet 5 libre en rotation et par exemple soumis à un moyen élastique 6.The apparatus according to the invention comprises an initial means for holding and guiding comprising a cylinder 4 here motorized as will be explained below and a roller 5 free in rotation and for example subjected to an elastic means 6.

La bande 1 passe entre le cylindre 4 et le galet 5 qui roule dans la gorge de la bande (figure 4).The strip 1 passes between the cylinder 4 and the roller 5 which rolls in the groove of the strip (FIG. 4).

Sur les figures 3 à 8, les divers moyens ne sont pas représentés en contact avec la bande 1 pour des raisons de clarté.In FIGS. 3 to 8, the various means are not shown in contact with the strip 1 for reasons of clarity.

En aval du cylindre 4 par rapport au sens de déplacement de la bande selon la flèche F (figure 3), on a prévu un guide d'alignement sous la forme d'une barrette 7 qui vient se loger dans la gorge 2 comme le montre bien la figure 5.Downstream of the cylinder 4 relative to the direction of movement of the strip according to the arrow F (FIG. 3), an alignment guide is provided in the form of a bar 7 which is received in the groove 2 as shown Figure 5.

En aval de la barrette 7, l'appareil comporte le moyen de cambrage de la bande 1 sous la forme ici de deux roues 8 et 9 superposées entre lesquelles passe ladite bande 1.Downstream of the bar 7, the device comprises the means for bending the strip 1 in the form here of two superimposed wheels 8 and 9 between which the said strip 1 passes.

Les jantes des roues 8 et 9, comme le montre bien la figure 6, présentent respectivement une face concave (roue 8) et une face sensiblement convexe (roue 9), la gorge 2 de la bande 1 étant tournée vers la roue concave 8 de telle sorte que la bande 1 se cambre transversalement comme représenté sur ladite figure 6.The rims of the wheels 8 and 9, as shown in FIG. 6, respectively have a concave face (wheel 8) and a substantially convex face (wheel 9), the groove 2 of the strip 1 being turned towards the concave wheel 8 of so that the strip 1 arches transversely as shown in said FIG. 6.

Le feuillard 3 est alimenté à partir d'une réserve, sous forme par exemple d'une bobine 10 (figure 3), par une rampe de guidage 11 (figures 2 et 3), dont l'extrémité arrive au voisinage des roues 8 et 9 tandis que ladite roue concave 8 comporte une nervure centrale circulaire 12 (figure 6) afin que celle-ci puisse appuyer sur le feuillard 3 et le positionner dans la gorge 2.The strip 3 is supplied from a reserve, for example in the form of a coil 10 (FIG. 3), by a guide ramp 11 (FIGS. 2 and 3), the end of which arrives in the vicinity of the wheels 8 and 9 while said concave wheel 8 has a circular central rib 12 (FIG. 6) so that the latter can press on the strip 3 and position it in the groove 2.

En sortie des roues de cambrage 8 et 9, on a prévu un moyen de remise à plat de la bande 1 sous la forme ici d'ailes de redressement 13, comme représenté sur la figure 7, qui passent progressivement d'une position oblique par rapport à l'horizontal jusqu'à une position sensiblement plane (figure 2).At the output of the bending wheels 8 and 9, there is provided a means for flattening the strip 1 in the form here of straightening wings 13, as shown in FIG. 7, which progressively pass from an oblique position by relative to the horizontal to a substantially flat position (Figure 2).

En outre, au-dessus des ailes de redressement, un moyen de maintien en position du feuillard 3 est aménagé sous la forme d'une barrette 14.In addition, above the straightening wings, a means for holding the strip 3 in position is arranged in the form of a bar 14.

En sortie des ailes de redressement 13, la bande 1 est ainsi remise à plat et passe entre deux cylindres de pression 15, 16 (figure 2, 3 et 8) destinés à écraser l'ensemble pour refermer les lèvres 2a et 2b de la gorge sur le feuillard 3.At the outlet of the straightening wings 13, the strip 1 is thus flattened and passes between two pressure cylinders 15, 16 (FIGS. 2, 3 and 8) intended to crush the assembly in order to close the lips 2a and 2b of the groove on the strip 3.

Comme le montrent en outre les figures 2 et 3, la roue 8 du moyen de cambrage et le cylindre 15 des moyens d'écrasement sont sollicités (comme le galet 5 précédemment décrit) par des moyens élastiques, schématisés sur les figures 1 et 2 par des ressorts tels que respectivement 17 et 18.As further shown in FIGS. 2 and 3, the wheel 8 of the cambering means and the cylinder 15 of the crushing means are stressed (like the roller 5 previously described) by elastic means, shown diagrammatically in FIGS. 1 and 2 by springs such as 17 and 18 respectively.

Dans l'exemple représenté, comme on peut le voir sur les figures 4 à 8, la plaque ou bande 1 est munie d'un retour sensiblement d'équerre 1' afin de former une cornière.In the example shown, as can be seen in Figures 4 to 8, the plate or strip 1 is provided with a substantially square return 1 'in order to form an angle.

Dans ce cas, le cylindre initial de guidage 4 (figures 2 et 4) et le cylindre 16 du moyen d'écrasement (figures 2 et 8) comportent une rainure ou gorge circulaire périphérique respectivement 4' et 16' pour le passage du retour d'équerre 1' de la plaque ou bande 1.In this case, the initial guide cylinder 4 (Figures 2 and 4) and the cylinder 16 of the crushing means (Figures 2 and 8) have a peripheral circular groove or groove 4 'and 16' respectively for the passage of the return d 'square 1' of the plate or strip 1.

En outre bien sûr, on a prévu des moyens pour entraîner la plaque ou bande 1 sous la forme ici d'un moteur d'entraînement schématisé en 19 (figure 2), lequel est destiné à entraîner en rotation le cylindre 4 (le galet 5 étant libre en rotation) et/ou au moins l'une des roues 8 et 9 du moyen de cambrage et/ou au moins l'un des cylindres d'écrasement 15, 16.In addition, of course, means have been provided for driving the plate or strip 1 in the form here of a drive motor shown diagrammatically at 19 (FIG. 2), which is intended to drive the cylinder 4 in rotation (the roller 5 being free to rotate) and / or at least one of the wheels 8 and 9 of the bending means and / or at least one of the crushing cylinders 15, 16 .

Suite à la description de l'appareil, le fonctionnement dudit appareil et par conséquent le procédé selon l'invention sont faciles à comprendre.Following the description of the device, the operation of said device and therefore the method according to the invention are easy to understand.

La plaque ou bande représentée sur la figure 1, ici en outre munie d'un retour sensiblement d'équerre 1', est introduite entre le cylindre 4 et le galet 5 et elle est entraînée comme expliqué ci-avant par le moteur 19 (figure 2) dans le sens de la flèche F (figure 3), le retour 1' se logeant dans la gorge circulaire 4'.The plate or strip shown in Figure 1, here further provided with a substantially square return 1 ', is introduced between the cylinder 4 and the roller 5 and it is driven as explained above by the motor 19 (Figure 2) in the direction of arrow F (Figure 3), the return 1 'being housed in the circular groove 4'.

Après un guidage par le guide d'alignement 7, la plaque ou bande est cambrée transversalement (figures 2, 3 et 6) tandis que le feuillard 3 est déposé en continu dans la gorge 2 de la plaque ou bande par la rampe de guidage 11.After guidance by the alignment guide 7, the plate or strip is bent transversely (Figures 2, 3 and 6) while the strip 3 is continuously deposited in the groove 2 of the plate or strip by the guide ramp 11 .

L'ensemble est ensuite remis à plat par les ailes de redressement 13 et la barrette 14 de maintien (figures 2, 3 et 7) avant de passer entre les cylindres 15 et 16 d'écrasement des lèvres 2a, 2b de la gorge 2 (figures 1, 2, 3 et 8), le retour 1' se logeant dans la gorge 16' du cylindre 16.The assembly is then flattened by the straightening wings 13 and the retaining bar 14 (FIGS. 2, 3 and 7) before passing between the cylinders 15 and 16 for crushing the lips 2a, 2b of the groove 2 ( Figures 1, 2, 3 and 8), the return 1 'being housed in the groove 16' of the cylinder 16.

La plaque ou bande 1 ainsi équipée peut être utilisée pour constituer tout type d'emballage muni ainsi d'un moyen de fixation incorporé.The plate or strip 1 thus equipped can be used to constitute any type of packaging thus provided with an incorporated fixing means.

En particulier, à partir d'une bande, on peut réaliser un emballage de protection sous forme d'une bague pour cercler au moins en partie un objet cylindrique.In particular, from a strip, it is possible to produce a protective packaging in the form of a ring to at least partially encircle a cylindrical object.

Avec une bande munie d'un retour sensiblement d'équerre, comme représenté, on peut protéger par exemple l'extrémité d'un tube ou d'un tuyau.With a strip provided with a substantially square return, as shown, one can protect for example the end of a tube or a pipe.
