Description

APPAREIL POUR. LA REALISATION DU THERMOSCELLAGE D'EMBALLAGES, NOTAMMENTAPPARATUS FOR. THE PRODUCTION OF PACKAGING THERMOSCELLING, IN PARTICULAR

ALIMENTAIRES.FOOD.

L'invention concerne un appareil pour réaliser le thermoscellage d'emballages, plus particulièrement destinés à l'industrie alimentaire.  The invention relates to an apparatus for heat sealing packaging, more particularly for the food industry.

Depuis longtemps déjà, on utilise de tels appareils, permettant d'emballer de manière étanche ou sensiblement étanche, à tout le moins aux liquides, des produits alimentaires, afin de faciliter leur transport ainsi que leur stockage provisoire, par 10 exemple dans un réfrigérateur.  Such devices have been used for a long time now, making it possible to pack foodstuffs in a sealed or substantially watertight manner, at least for liquids, in order to facilitate their transport as well as their temporary storage, for example in a refrigerator.

Ces emballages sont constitués d'un papier thermoscellable, que l'on replie, et à l'intérieur duquel sont positionnés les aliments en question. Il convient donc, afin d'assurer la fermeture effective de l'emballage, d'obturer les trois bords ouverts du sac ainsi constitué. Cette obturation est réalisé au moyen d'un tel appareil.  These packages consist of a heat-sealable paper, which is folded, and inside which are positioned the food in question. It is therefore necessary, in order to ensure the effective closure of the package, to seal the three open edges of the bag thus formed. This closure is achieved by means of such a device.

L'emballage en question est constitué de matière synthétique ou de papier, dont. l'intérieur est enduit d'une couche de matériau thermoscellable, tel que par exemple du polypropylène.  The packaging in question consists of synthetic material or paper, of which. the interior is coated with a layer of heat-sealable material, such as for example polypropylene.

Dans les appareils de thermoscellage de l'art antérieur, ceux-ci sont munis d'un socle au niveau duquel est articulé un bras supérieur rabattable sur le socle. Ce bras supérieur est muni d'un mors de chauffage, en forme de U, venant coopérer avec un mors de forme correspondante ménagé au niveau du socle. L'emballage en question, et notamment les trois bords à obturer sont positionnés au niveau de ce mors inférieur.  In prior art heat sealing apparatus, these are provided with a base at which is articulated an upper arm foldable on the base. This upper arm is provided with a heating jaw, U-shaped, cooperating with a jaw of corresponding shape formed at the base. The packaging in question, and in particular the three edges to be closed are positioned at this lower jaw.

Sous l'effet de la chaleur dégagée par les résistances chauffantes intégrées dans le mors de scellage, on aboutit à la fusion locale de la matière plastique, assurant ainsi son collage ou scellage, et obturant ainsi l'emballage.  Under the effect of the heat released by the heating resistors integrated in the sealing jaw, it leads to the local melting of the plastic material, thus ensuring its bonding or sealing, and thus closing the packaging.

Si, sur le plan technique, les appareils de l'art antérieur donnent satisfaction, en revanche, l'expérience démontre que la pression exercée par l'utilisateur doit souvent être importante, afin d'assurer une fermeture effective et complète des bords de l'emballage ainsi réalisé. En effet, il n'est pas rare d'observer localement des zones au niveau desquelles le scellage n'est pas intervenu, constituant autant de points de faiblesse de l'étanchéité de l'emballage en résultant.  If, technically, the apparatus of the prior art are satisfactory, however, experience shows that the pressure exerted by the user must often be important, to ensure effective and complete closure of the edges of the packaging thus produced. Indeed, it is not uncommon to locally observe areas where the seal has not intervened, constituting so many points of weakness of the sealing of the resulting packaging.

L'objet de la présente invention est de s'affranchir de cet inconvénient.  The object of the present invention is to overcome this disadvantage.

Elle vise un appareil pour la réalisation du thermoscellage d'emballages, notamment alimentaires: comprenant un socle, au niveau de l'un des bords duquel est articulé un bras supérieur en forme de U, pourvu au niveau inférieur de ces trois branches d'un mors de scellage, intégrant une résistance chauffante, et positionné en vis à vis d'un mors de forme complémentaire ménagé sur le socle; ledit bras supérieur étant muni d'une poignée fixe, destinée à permettre son 10 ouverture et sa fermeture par rapport à son axe d'articulation sur le socle.  It aims an apparatus for the realization of heat sealing packaging, including food: comprising a base, at one of which is articulated an upper arm U-shaped, provided at the lower level of these three branches of a sealing jaws, incorporating a heating resistor, and positioned opposite a jaw of complementary shape formed on the base; said upper arm being provided with a fixed handle, intended to allow its opening and closing relative to its hinge axis on the base.

L'appareil selon l'invention se caractérise en ce que ledit bras supérieur est muni en outre d'une poignée montée pivotante par rapport à la poignée fixe, et dont les deux extrémités libres sont munies d'une came de serrage, destinées chacune à coopérer avec un galet de serrage positionné sur le socle, à l'aplomb desdites cames lorsque le bras supérieur est rabattu sur le socle.  The apparatus according to the invention is characterized in that said upper arm is further provided with a handle pivotally mounted relative to the fixed handle, and whose two free ends are provided with a clamping cam, each intended for cooperate with a clamping roller positioned on the base, in line with said cams when the upper arm is folded down on the base.

Ce faisant, lorsque l'emballage est positionné au sein du socle, et le bras supérieur rabattu sur celui-ci, un simple pivotement de la poignée mobile induit la coopération des cames avec les galets de serrage, assurant ainsi, par le choix d'un chemin de came approprié, une pression uniforme et efficace des deux mors respectivement du bras et du socle, et donc corollairement la fermeture effective et totale de l'emballage résultant de l'opération de scellage.  In doing so, when the package is positioned within the base, and the upper arm folded on it, a simple pivoting of the movable handle induces the cams to cooperate with the clamping rollers, thus ensuring, by the choice of a suitable cam path, a uniform and effective pressure of the two jaws respectively of the arm and the base, and therefore corollary effective and total closure of the package resulting from the sealing operation.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit donné à titre indicatif et non limitatif à l'appui des figures annexées.  The manner in which the invention can be realized and the advantages which result from it will emerge more clearly from the exemplary embodiment which follows given by way of indication and not limitation in support of the appended figures.

La figure 1 est une représentation schématique en perspective de l'appareil conforme à l'invention représenté en position fermée.  Figure 1 is a schematic perspective view of the apparatus according to the invention shown in the closed position.

La figure 2 est une vue analogue à la figure 1, l'appareil étant en position ouverte. La figure 3 est une vue latérale de l'appareil conforme à l'invention.  Figure 2 is a view similar to Figure 1, the apparatus being in the open position. Figure 3 is a side view of the apparatus according to the invention.

La figure 4 est une vue de détail d'une came de serrage et d'un galet de serrage.  Figure 4 is a detail view of a clamp cam and a clamping roller.

On a donc représenté sur la figure 1, l'appareil de thermoscellage conforme à l'invention. Fondamentalement, celui-ci se compose d'un socle (1), de forme-sensiblement carrée ou rectangulaire, destinée à reposer sur un comptoir ou une table ou tout support équivalent.  It is therefore shown in Figure 1, the heat sealing apparatus according to the invention. Basically, it consists of a base (1), shape-substantially square or rectangular, intended to rest on a counter or table or any equivalent support.

Ce socle (1) reçoit un plateau (3), par exemple réalisé en acier inoxydable, destiné à recevoir l'emballage à fermer par la technique de thermoscellage. Cet emballage étant typiquement constitué d'une feuille de papier repliée, enduite ou revêtue sur sa face interne d'un matériau. thermoscellable et à caractère alimentaire, tel que notamment du polypropylène. Le produit à emballer a été positionné à l'intérieur de la. feuille de papier ainsi pliée, le pli étant situé hors des zones de sceallage.  This base (1) receives a tray (3), for example made of stainless steel, for receiving the package to be closed by the heat sealing technique. This packaging is typically made of a folded paper sheet, coated or coated on its inner surface with a material. heat-sealable and food-grade, such as in particular polypropylene. The product to be packaged has been positioned inside the. folded paper sheet, the fold being located outside the sceallage areas.

Au niveau du socle (1) est articulé en (7) un bras supérieur (2), que l'on peut mieux observer au sein de la figure 2.  At the base (1) is articulated in (7) an upper arm (2), which can be better seen in Figure 2.

Ce bras supérieur (2) est en fonte de U, dont la face inférieure de chacune des trois branches reçoit un mors (12), continu, également en forme de U, et constituant dans l'exemple décrit le mors mâle. Ce mors reçoit une résistance chauffante (non représentée) alimentée électriquement par actionnement de l'interrupteur (15), positionné sur la face supérieure du bras (2), relié au secteur.  This upper arm (2) is U cast iron, the lower face of each of the three branches receives a jaw (12), continuous, also U-shaped, and constituting in the example described the male jaw. This jaw receives a heating resistor (not shown) powered electrically by actuation of the switch (15), positioned on the upper face of the arm (2), connected to the sector.

Ce mors mâle est destiné à coopérer avec un mors femelle (13), de forme complémentaire lorsque le bras (2) est rabattu intégralement sur le socle (1). Ce mors femelle (13) est positionné sur la surface supérieure du socle (1), à l'aplomb du mors mâle (12) lorsque le bras supérieur (2) est rabattu sur le socle (1).  This male jaw is intended to cooperate with a female jaw (13) of complementary shape when the arm (2) is folded integrally on the base (1). This female jaw (13) is positioned on the upper surface of the base (1), directly above the male jaw (12) when the upper arm (2) is folded down on the base (1).

Avantageusement, compte-tenu de la chaleur dégagée par le mors (12), celui-ci est protégé de tout contact par une glissière de protection latérale (8).  Advantageously, given the heat released by the jaw (12), it is protected from contact by a side guard (8).

Le bras supérieur (2) est manipulé par une poignée fixe (4), fermant la partie supérieure du U. Selon une caractéristique de l'invention, est ménagée au voisinage de cette poignée (4), une poignée (5), donc parallèle à la poignée (4), et montée pivotante par rapport à celle-ci, et notamment par rapport à un axe d'articulation (14), coaxial avec la poignée (4).  The upper arm (2) is manipulated by a fixed handle (4), closing the upper part of the U. According to a characteristic of the invention, is formed in the vicinity of this handle (4), a handle (5), so parallel to the handle (4), and pivotally mounted relative thereto, and in particular with respect to a hinge axis (14), coaxial with the handle (4).

Les deux extrémités libres de cette poignée pivotante (5) sont munies d'une came (6), destinée à coopérer avec un galet de serrage (9), solidarisé au socle (1) au moyen d'une patte (11) de fixation. Bien évidemment, les cames (6) ne peuvent coopérer avec les galets (11) de serrage (9) que lorsque le bras supérieur (2) est rabattu sur le socle (1) , tel que représenté sur la figure 1.  The two free ends of this pivoting handle (5) are provided with a cam (6), intended to cooperate with a clamping roller (9), secured to the base (1) by means of a bracket (11). . Of course, the cams (6) can cooperate with the rollers (11) clamping (9) only when the upper arm (2) is folded down on the base (1), as shown in Figure 1.

On a mieux représenté au sein de la figure 4, l'ensemble constitué par l'une des cames de serrage (6) et le galet de serrage (9) avec lequel elle est destinée à coopérer.  The assembly constituted by one of the clamping cams (6) and the clamping roller (9) with which it is intended to cooperate has been better represented in FIG.

Cette came (6) définit un chemin de came (10) sensiblement circulaire, permettant, lorsque la poignée (5) est pivotée par rapport à l'axe d'articulation (14), une coopération effective du galet de serrage (9) avec le chemin de came (10), et corollairement, le serrage accentué du bras supérieur (2) sur le socle (1) et donc, une pénétration effective et sensiblement uniforme du mors de scellement (12) au sein du mors femelle (13), constituée, ainsi qu'on peut l'observer sur la figure 4, d'une rainure 1 o de forme et dimensions complémentaires.  This cam (6) defines a cam path (10) substantially circular, allowing, when the handle (5) is pivoted relative to the hinge pin (14), effective cooperation of the clamping roller (9) with the cam path (10) and, consequently, the accentuated clamping of the upper arm (2) on the base (1) and therefore an effective and substantially uniform penetration of the sealing jaw (12) into the female jaw (13) , constituted, as can be seen in Figure 4, a groove 1 o shape and complementary dimensions.

Afin de favoriser la coopération du chemin de came (10) avec le galet de serrage, celui-ci est monté fou en rotation.  In order to promote cooperation of the cam path (10) with the clamping roller, it is rotatably mounted.

Ce faisant, lorsque l'utilisateur souhaite procéder au scellage effectif et donc à la fermeture d'un emballage, après positionnement de celui-ci sur le plateau (3) de telle sorte que les parties ouvertes de l'emballage dépassent au niveau des trois branches du mors (13), il appuie par le biais de la poignée (4) sur le bras supérieur (2), afin de rabattre celuici sur le socle (1), puis en bout de course, fait pivoter la poignée (5) par rapport à l'axe d'articulation (14), jusqu'à faire coopérer les cames (6) avec les galets de serrage (9).  In doing so, when the user wishes to proceed with the actual sealing and therefore the closing of a package, after positioning it on the tray (3) so that the open parts of the package exceed the level of the three branches of the jaw (13), it presses by means of the handle (4) on the upper arm (2), to fold it on the base (1), then at the end of stroke, rotates the handle (5) relative to the hinge pin (14), until the cams (6) cooperate with the clamping rollers (9).

Il assure ce faisant une pression effective, sensiblement uniforme, induisant une coopération efficace du mors chauffant (12) avec le mors (13) et corollairement, le thermoscellage continu des trois bords ouverts de l'emballage, jusqu'à aboutir à une fermeture effective et étanche de celui-ci.  It ensures an effective pressure, substantially uniform, inducing an effective cooperation of the heating jaw (12) with the jaw (13) and corollary, the continuous heat sealing of the three open edges of the package, until an effective closure and waterproof of it.

On conçoit dès lors tout l'intérêt de la présente invention, dans la mesure où il permet de simplifier de manière importante le travail du manipulateur, lui permettant de réduire l'effort nécessaire à la fermeture étanche de l'emballage, tout en assurant une qualité de fermeture et donc d'étanchéité, donc plus satisfaisante, notamment en relation avec des produits alimentaires.  It is therefore conceivable that the whole of the interest of the present invention, insofar as it makes it possible to greatly simplify the work of the manipulator, enabling him to reduce the effort required to seal the package, while at the same time ensuring quality of closure and therefore sealing, so more satisfactory, especially in relation to food products.
