Abstract

The device has six arms (3) disposed on a rotating table (2), where each arm comprises a mandrel (4) and two clips (5). A sheet loader moves a flexible sheet to the clips when the clips are opened. A sonotrode descends and is pressed against the mandrel around which the sheet is wound, to weld the sheet in order to form a tubular body of a package, when the clips are closed. A cam pushes a part of the body from the mandrel.

Description

2878231 12878231 1

La présente invention concerne un dispositif de fabrication d'un emballage tubulaire.  The present invention relates to a device for manufacturing a tubular packaging.

On connaît par le document FR 2 777 863 un emballage formé par une feuille refermée sur elle-même pour former un tube, le cylindre 5 recevant un fond et un couvercle.  FR 2 777 863 discloses a package formed by a sheet closed on itself to form a tube, the cylinder 5 receiving a bottom and a lid.

Ce type d'emballage s'avère notamment bien adapté au conditionnement de matière pulvérulente.  This type of packaging proves particularly well suited to the packaging of powdery material.

En revanche, les dispositifs de fabrication des emballages tubulaires de ce type s'avèrent insatisfaisants.  On the other hand, the devices for manufacturing tubular packaging of this type prove to be unsatisfactory.

En effet, le formage d'un tube à partir d'une feuille plane peut s'avérer délicat à gérer sur un plan industriel.  Indeed, the forming of a tube from a flat sheet may be difficult to manage on an industrial level.

L'invention a donc pour but de proposer un dispositif de fabrication d'un emballage tubulaire qui permet d'atteindre des cadences industrielles importantes.  The object of the invention is therefore to propose a device for manufacturing a tubular package which makes it possible to reach important industrial rates.

Un autre but de l'invention est de proposer un procédé et un dispositif de fabrication d'un emballage tubulaire qui soit facilement paramétrable.  Another object of the invention is to provide a method and a device for manufacturing a tubular package that is easily configurable.

Un autre but de l'invention est de proposer un procédé et un dispositif de fabrication d'un emballage tubulaire qui soit le plus 20 économique à l'usage.  Another object of the invention is to provide a method and a device for manufacturing a tubular package which is the most economical to use.

L'invention concerne un dispositif de fabrication d'un emballage tubulaire ayant un corps constitué d'une feuille souple, caractérisé en ce qu'il comprend un plateau rotatif sur lequel est disposé au moins un bras présentant un mandrin et deux pinces articulées entre une position d'ouverture dans laquelle les pinces forment entre elles un angle d'environ 180 et une position de fermeture dans laquelle les pinces sont refermées autour du mandrin, chaque bras pouvant être successivement en regard: - des moyens de stockage d'amenée d'une feuille sur les pinces, 30 les pinces étant en position d'ouverture, - des moyens de soudage, les pinces étant en position de fermeture, - des moyens d'éjection d'un corps formé par une feuille soudée sur elle-même.  The invention relates to a device for manufacturing a tubular package having a body consisting of a flexible sheet, characterized in that it comprises a rotary plate on which is disposed at least one arm having a mandrel and two clamps articulated between a opening position in which the clamps form between them an angle of about 180 and a closed position in which the clamps are closed around the mandrel, each arm can be successively opposite: - supply storage means of a sheet on the clamps, the clamps being in the open position, - welding means, the clamps being in the closed position, - ejection means of a body formed by a sheet welded on itself.

L'idée à la base de l'invention est de former un corps tubulaire a parti d'une feuille souple en pliant celle-ci autour d'un mandrin grâce à deux pinces. La formation du corps se fait de manière purement mécanique et notamment sans ventouse ou autre système d'aspiration. Cela se traduit par un dispositif simple à mettre en place et à maintenir qui peut de plus accepter des cadences importantes.  The idea underlying the invention is to form a tubular body from a flexible sheet by folding it around a mandrel with two clamps. The formation of the body is purely mechanical and in particular without suction cup or other suction system. This results in a simple device to set up and maintain that can also accept significant rates.

De plus le dispositif comprend des moyens de mise en place d'un fond sur le corps et des moyens de mise en place d'un couvercle sur le corps.  In addition, the device comprises means for placing a bottom on the body and means for placing a lid on the body.

De façon avantageuse, chaque bras présente un élément à came pouvant pousser un corps formé sur le bras ce qui permet de ménager une 10 zone de réception pour un fond.  Advantageously, each arm has a cam member that can push a body formed on the arm to provide a receiving area for a bottom.

Selon une forme de réalisation avantageuse, le mandrin présente au moins une nervure longitudinale.  According to an advantageous embodiment, the mandrel has at least one longitudinal rib.

Dans cette forme de réalisation, les moyens de soudage sont constitués par une sonotrode ayant une surface de soudage plane pouvant venir en appui contre le mandrin lors du soudage. Grâce à ces dispositions, les saillies présentes sur le corps consécutives au sondage sont d'une part sur la face intérieure du corps et d'autre part sont orientées selon une génératrice du corps; l'effet est donc double: la face extérieure du corps est lisse et les saillies ne s'opposent pas à une éjection du corps formé sur le mandrin.  In this embodiment, the welding means consist of a sonotrode having a flat welding surface that can bear against the mandrel during welding. Thanks to these provisions, the projections present on the body consecutive sounding are on the one hand on the inner side of the body and on the other hand are oriented along a generatrix of the body; the effect is therefore double: the outer face of the body is smooth and the projections do not oppose ejection of the body formed on the mandrel.

De préférence, le dispositif comprend six bras orientés à 60 , ce qui permet d'importante cadence de production.  Preferably, the device comprises six arms oriented at 60, which allows a high production rate.

Selon une possibilité, les moyens de mise en place d'un fond sur le corps comprennent un plateau rotatif à quatre têtes, chaque tête ayant 25 un support de fond.  According to one possibility, the means for placing a bottom on the body comprises a four-headed rotating plate, each head having a bottom support.

Similairement, les moyens de mise en place d'un couvercle comprennent un plateau rotatif à quatre têtes, chaque tête ayant un support de couvercle.  Similarly, the means for placing a lid comprises a four-headed rotary plate, each head having a lid support.

De plus, le dispositif comprend un convoyeur linéaire juxtaposé au plateau rotatif supportant un moyen de dosage pouvant introduire une dose de matériau dans le corps et les moyens de mise en place d'un couvercle sur le corps.  In addition, the device comprises a linear conveyor juxtaposed to the turntable supporting a dosing means that can introduce a dose of material into the body and the means for placing a lid on the body.

On note également que le dispositif comprend une cellule optique permettant de détecter la présence d'un fond sur le corps. Cette disposition permet de s'assurer qu'aucun corps sans fond n'est engagé sur le convogeur en ligne et n'est donc rempli de matériau à conditionner.  Note also that the device comprises an optical cell for detecting the presence of a bottom on the body. This arrangement ensures that no bottomless body is engaged on the in-line driver and is therefore filled with material to be packaged.

2878231 3 Pour sa bonne compréhension, l'invention est décrite en référence au dessin ci-annexé représentant, à titre d'exemple non limitatif, une forme de réalisation d'un dispositif selon l'invention.  For good understanding, the invention is described with reference to the accompanying drawing showing, by way of non-limiting example, an embodiment of a device according to the invention.

Figure 1 représente le dispositif dans sa totalité en vue de 5 dessus, Figure 2 représente en vue de côté un poste de désempilage de feuilles, Figure 3 représente en vue de côté un poste de formage d'un corps d'emballage, Figure 4 représente un poste de soudage d'un corps en vue de face, Figure 5 représente le poste de soudage en vue de côté, Figure 6 représente un poste de mise en place d'un fond sur le corps, Figure 7 représente un poste de mise en place d'un couvercle sur le corps On commencera la description du dispositif en se référant à la figure 1.  1 shows the entire device in plan view, FIG. 2 is a side view of a destacking station, FIG. 3 is a side view of a forming station of a packaging body, FIG. a welding station of a body in front view, Figure 5 shows the welding station in side view, Figure 6 shows a position of placement of a bottom on the body, Figure 7 shows a position of setting Place a cover on the body The description of the device will begin with reference to FIG.

Cette figure, qui montre l'ensemble du dispositif en vue de dessus, permet de bien comprendre la structure générale du dispositif.  This figure, which shows the entire device in plan view, allows to understand the general structure of the device.

Comme on peut le voir, le dispositif est construit autour d'un plateau rotatif 2 qui comprend six bras 3. Ce plateau rotatif 2 est animé d'un mouvement d'avance rotatif sur 360 . La commande de ce plateau rotatif est réalisée par un électronique dont le pupitre de commande est représenté.  As can be seen, the device is built around a turntable 2 which comprises six arms 3. This turntable 2 is driven by a rotary advance movement 360. The control of this turntable is performed by an electronic control console is shown.

Chacun des bras 3 présente, à son extrémité, un mandrin 4. Dans l'exemple représenté, ce mandrin 4 est de forme cylindrique. Comme cela apparaîtra plus loin dans la description, le mandrin confère sa section à un emballage fabriqué par le dispositif. Le mandrin 4 peut donc présenter les différentes formes de section, par exemple une section triangulaire, carré, elliptique, ... On note que la surface du mandrin 4 est pourvue de nervures orientées selon sa génératrice.  Each of the arms 3 has, at its end, a mandrel 4. In the example shown, this mandrel 4 is cylindrical in shape. As will become apparent later in the description, the mandrel gives its section to a package made by the device. The mandrel 4 may therefore have the different sectional shapes, for example a triangular, square, elliptical section, etc. It will be noted that the surface of the mandrel 4 is provided with ribs oriented along its generatrix.

En plus d'un mandrin 4, chaque bras 3 est équipé de deux pinces 5 disposées symétriquement par rapport à un plan vertical passant 35 par l'axe du mandrin 4.  In addition to a mandrel 4, each arm 3 is equipped with two clamps 5 arranged symmetrically with respect to a vertical plane passing through the axis of the mandrel 4.

2878231 4 Chacune des pinces 5 est articulée par rapport au bras. Deux vérins 6 pneumatiques permettent d'agir sur, respectivement, chacune des pinces 5. Les pinces 5 sont donc susceptibles de prendre deux positions, à savoir une position ouverte dans laquelle les deux pinces 5 forment, entre elles, un angle d'environ 180 et une position fermée dans laquelle les pinces 5 pivotent l'une vers l'autre grâce à l'action de leur vérin 6 respectif. Lorsqu'elles sont en position fermée, les pinces viennent entourer le mandrin.  2878231 4 Each of the clamps 5 is articulated relative to the arm. Two pneumatic cylinders 6 make it possible to act on each of the clamps 5, respectively. The clamps 5 are therefore capable of assuming two positions, namely an open position in which the two clamps 5 form, between them, an angle of approximately 180.degree. and a closed position in which the clamps 5 pivot towards each other by the action of their respective jack 6. When in the closed position, the clamps surround the mandrel.

Autour du plateau rotatif sont disposés quatre postes.  Around the turntable are four positions.

Il s'agit d'un poste 7 de stockage et d'amenée de feuilles comprenant un magasin 8 dans lequel est placée une pile de feuilles, de forme carrée ou rectangulaire. Les feuilles sont stockées à l'horizontale comme on peut le voir. Un vérin 1 1 permet de faire avance les feuilles.  This is a station 7 for storing and supplying sheets comprising a magazine 8 in which is placed a stack of sheets, of square or rectangular shape. The leaves are stored horizontally as can be seen. A jack 1 1 makes it possible to advance the sheets.

Adjacent au poste 7, le dispositif présente un poste de soudure 9 à ultra son. Le poste de soudure à ultra son présente une sonotrode 10 dont la surface de soudage est parallèle à l'axe du mandrin.  Adjacent station 7, the device has a welding station 9 ultra son. The ultrasonic welding station has a sonotrode 10 whose welding surface is parallel to the axis of the mandrel.

Le dispositif comprend également un poste de dépôt de fond 12. Ce poste 12 présente un plateau rotatif 13 orienté dans un plan vertical et dans l'axe du mandrin. Le plateau rotatif présente quatre têtes 14 pouvant recevoir des fonds encollés.  The device also comprises a bottom deposition station 12. This station 12 has a rotating plate 13 oriented in a vertical plane and in the axis of the mandrel. The turntable has four heads 14 that can receive glued bottoms.

Le dispositif présente, par ailleurs, un convoyeur en ligne 15 juxtaposée du plateau rotatif 2. La connexion du plateau rotatif 2 et du convoyeur en ligne 15 se fait au niveau d'un poste adjacent au poste 12 de mise en place d'un fond.  The device has, moreover, an in-line conveyor 15 juxtaposed with the turntable 2. The connection of the turntable 2 and the in-line conveyor 15 is at a station adjacent the station 12 for setting up a bottom .

Dans l'exemple représenté, le convoyeur 17 en ligne est bordé d'un poste de dosage d'un matériau de remplissage et d'un poste de mise en place d'un couvercle 17.  In the example shown, the in-line conveyor 17 is lined with a metering station for a filling material and a station for placing a cover 17.

Comme on peut le voir sur la figure 7, le convoyeur 13 présente des plateaux supports 18 circulaires bordés de doigts 19 verticaux.  As can be seen in FIG. 7, the conveyor 13 has circular support plates 18 flanked by vertical fingers 19.

Le dispositif est donc mis en oeuvre de la manière suivante.  The device is implemented in the following manner.

Tout d'abord, une feuille est amenée depuis le magasin 8 jusqu'à l'un des bras 3.  First, a sheet is fed from the magazine 8 to one of the arms 3.

Le déplacement d'une feuille se fait par un chargeur de feuilles entraîné par le vérin 11.  The movement of a sheet is done by a sheet feeder driven by the cylinder 11.

La feuille est alors réceptionnée sur les pinces 5 ouvertes du bras.  The sheet is then received on the open arms clamps.

2878231 5 Le plateau rotatif 2 est alors entraîné sur une course de 60 pour amener la feuille au niveau du poste 9 de soudure.  The turntable 2 is then driven over a course of 60 to bring the sheet to the welding station 9.

Les pinces 5 sont alors en position fermée, de sorte que la feuille s'enroule autour du mandrin 4. La dimension de la feuille est telle 5 que les deux bords de la feuille se chevauchent.  The clamps 5 are then in the closed position, so that the sheet wraps around the mandrel 4. The size of the sheet is such that both edges of the sheet overlap.

Les pinces 5 étant fermées et la feuille étant enroulée autour du mandrin 4, la sonotrode 10 descend et se presse contre le mandrin 4 pour effectuer le soudage de la feuille.  The clamps 5 being closed and the sheet being wound around the mandrel 4, the sonotrode 10 descends and is pressed against the mandrel 4 to effect the welding of the sheet.

Le corps tubulaire de l'emballage est alors formé.  The tubular body of the package is then formed.

A l'étape suivante correspondant à une avance angulaire de 60 , le corps est poussé du mandrin 4. Cette poussée est réalisée par une came qui permet de faire dépasser du mandrin 4 une partie du corps.  In the next step corresponding to an angular advance of 60, the body is pushed from the mandrel 4. This thrust is achieved by a cam which makes it possible to extend mandrel 4 a part of the body.

Le plateau rotatif effectue une nouvelle incrémentation angulaire de 60 pour se trouver en face du poste 12 d'encollage de fond. Là un fond, c'est-à-dire une coupelle en matière plastique présentant un épaulement, est engagé dans le corps. Le fond étant préalablement enduit d'un adhésif, il est alors collé au corps.  The turntable performs a new angular increment of 60 to be in front of the station 12 of background sizing. There a bottom, that is to say a plastic cup having a shoulder, is engaged in the body. The bottom being previously coated with an adhesive, it is then glued to the body.

Le plateau rotatif effectue une nouvelle incrémentation de 60 , le corps muni de son fond est alors aligné avec le convoyeur en ligne 15.  The turntable performs a new increment of 60, the body provided with its bottom is then aligned with the in-line conveyor 15.

Un contrôle optique est opéré pour vérifier qu'un fond est bien engagé sur le corps.  An optical check is made to verify that a bottom is well engaged on the body.

Si le contrôle optique ne détecte pas de fond, le plateau tourne de 60 et le corps sans fond est éjecté.  If the optical control does not detect a background, the turntable rotates by 60 and the bottomless body is ejected.

Dans le cas où le contrôle optique détecte le fond, le corps muni 25 à son fond est transféré sur le convoyeur linéaire 15.  In the case where the optical control detects the bottom, the body provided at its bottom is transferred to the linear conveyor 15.

Le corps est mis en place sur le plateau en étant guidé par les doigts et passe d'une orientation horizontale à une orientation verticale.  The body is placed on the tray by being guided by the fingers and moves from a horizontal orientation to a vertical orientation.

Le corps est rempli de la matière qu'il doit conditionner, puis un couvercle est déposé. Le couvercle est généralement constitué d'un anneau présentant un épaulement venant se mettre en place sur le corps et un capot articulé sur l'anneau par une charnière film.  The body is filled with the material that it has to pack, then a lid is put down. The cover is generally constituted by a ring having a shoulder coming to be placed on the body and a cover hinged to the ring by a film hinge.

L'invention fournit ainsi un dispositif extrêmement rapide et fiable de fabrication d'un emballage tubulaire formé par une feuille souple. L'un des facteurs importants de cette rapidité et fiabilité tient au fait que le corps est formé mécaniquement par deux pinces qui se ferment l'une sur l'autre.  The invention thus provides an extremely fast and reliable device for manufacturing a tubular package formed by a flexible sheet. One of the important factors of this speed and reliability is that the body is mechanically formed by two clamps that close on one another.

2878231 6 En outre, ce dispositif est très facilement paramétrable en changeant la forme ou les dimensions du mandrin.  In addition, this device is very easily configurable by changing the shape or dimensions of the mandrel.

Bien entendu, l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple non limitatif, mais elle 5 embrasse au contraire toutes les formes de réalisation.  Of course, the invention is not limited to the embodiment described above by way of non-limiting example, but on the contrary embraces all the embodiments.

Ainsi, le fond et le couvercle pourraient être retenus sur le corps par un système de liaison mécanique à la place. De même, d'autres opérations peuvent être intégrées sur le convoyeur en ligne comme le collage d'étiquette ou une impression par jet d'encre.  Thus, the bottom and the lid could be held on the body by a mechanical connection system instead. Similarly, other operations may be integrated on the in-line conveyor such as label sticking or ink jet printing.
