Abstract
Description
La présente invention a pour objet un dispositif permettant de séparer deux films ou feuilles ayant tendance à adhérer l!un à l'autre, notamment les deux côtés d'un sachet en matière plastique. The present invention relates to a device for separating two films or sheets tending to adhere to one another, in particular the two sides of a plastic bag.
Pour différentes raisons, soit de fabrication, notamment suite à une découpe, soit d'effet électrostatique, il n'est pas toujours aisé de séparer deux films en matière plastique, particulièrement quand ils sont de très faible épaisseur, comme les deux côtés d'un sachet
La présente invention a pour but de proposer un dispositif mécanique de conception simple, manoeuvrable à la main ou automatisable, permettant de séparer aisément deux films ou feuilles ayant tendance à adhérer l'un à l'autre. For different reasons, either manufacturing, especially after cutting, or electrostatic effect, it is not always easy to separate two plastic films, especially when they are very thin, like the two sides of A sachet
The object of the present invention is to propose a mechanical device of simple design, maneuverable by hand or automated, making it possible to easily separate two films or sheets which tend to adhere to one another.
Le dispositif objet de la présente invention comporte un socle, de préférence solidarisé à un support, portant deux bras dont l'un est fixe et l'autre est monté pivotant sur ledit socle et maintenu écarté de l'autre bras par un moyen élastique quand le dispositif est en position de repos. The device object of the present invention comprises a base, preferably secured to a support, carrying two arms, one of which is fixed and the other is pivotally mounted on said base and kept apart from the other arm by elastic means when the device is in the rest position.
Chacun des bras comporte à son extrémité et intérieurement une zone en une matière présentant des caractéristiques d'adhérence, lesdites zones d'adhérence étant en contact lorsque le bras mobile est positionné en regard du bras fixe. Each of the arms has at its end and internally a zone made of a material having adhesion characteristics, said adhesion zones being in contact when the mobile arm is positioned opposite the fixed arm.
Les zones d'adhérence peuvent consister par exemple en des ventouses ou des patins de matière caoutchouteuse ou autre matière à fort coefficient de frottement. The adhesion zones may consist, for example, of suction cups or pads of rubbery material or other material with a high coefficient of friction.
Pour séparer deux pièces ayant tendance à adhérer l'une à l'autre il suffit de les positionner dans un plan parallèle à celui du pivotement du bras mobile, l'une d'elles en appui contre le bras fixe, le pivotement dudit bras mobile ayant pour effet, lorsque les deux zones d'adhérence viennent en contact, d'amorcer un mouvement de cisaillement séparant lesdites pièces. To separate two parts which tend to adhere to one another, it suffices to position them in a plane parallel to that of the pivoting of the movable arm, one of them pressing against the fixed arm, the pivoting of said movable arm. having the effect, when the two adhesion zones come into contact, to initiate a shearing movement separating said parts.
I1 est à noter que le pivotement du bras mobile peut être réalisé manuellement ou de façon automatique au moyen d'un dispositif approprié. It should be noted that the pivoting of the mobile arm can be carried out manually or automatically by means of an appropriate device.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexe, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which relates to the attached drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé
- la figure 1 représente une vue en perspective d'un dispositif selon l'invention, en position de repos.In the attached drawing
- Figure 1 shows a perspective view of a device according to the invention, in the rest position.
- la figure 2 représente une vue en perspective du meme dispositif en cours de fonctionnement. - Figure 2 shows a perspective view of the same device during operation.
- les figures 3a, 3b et 3c représentent en vue schématique de face différentes étapes de la séparation des deux côtés d'un sachet en film plastique au moyen d'un dispositif selon l'invention. - Figures 3a, 3b and 3c show in schematic front view different stages of separation of the two sides of a plastic film bag using a device according to the invention.
Si on se réfère à la figure 1 on peut voir qu'un dispositif selon l'invention comporte un socle 1 supportant un corps 10 sensiblement vertical à l'extrémité supérieure duquel d'une part s'étend sensiblement perpendiculairement un bras 2 et d'autre part peut pivoter dans un plan vertical autour d'un axe 11, solidaire du corps 10, un bras 3 rappelé en position verticale par un ressort non visible sur la figure. If we refer to Figure 1 we can see that a device according to the invention comprises a base 1 supporting a body 10 substantially vertical at the upper end of which on the one hand extends substantially perpendicularly an arm 2 and on the other hand can pivot in a vertical plane around an axis 11, integral with the body 10, an arm 3 returned to the vertical position by a spring not visible in the figure.
I1 est à noter que le socle 1 est solidarisable par des moyens classiques, comme des vis 12, à un support, non représenté, tel un présentoir support de publicités. I1 it should be noted that the base 1 can be secured by conventional means, such as screws 12, to a support, not shown, such as an advertising display stand.
Si on se réfère également à la figure 2 on peut voir qu'en appliquant une pression P sur le bras 3, qui comporte à cet effet une poignée 32, on réalise un mouvement de cisaillement du bras 3 par rapport au bras 2, avec, entre les deux positions extrêmes du bras 3, une position où les bras 2 et 3 sont en regard. If we also refer to FIG. 2, we can see that by applying pressure P on the arm 3, which for this purpose has a handle 32, a shearing movement of the arm 3 is carried out relative to the arm 2, with, between the two extreme positions of the arm 3, a position where the arms 2 and 3 are opposite.
Les bras 2 et 3 comportent chacun à ieur extrémité, sur leur face interne, respectivement 20 et 30, une zone d'adhérence, respectivement 21 et 31, les zones d'adhérence 21 et 31 étant mises en contact lorsque, par pivotement du bras 3, les bras 2 et 3 sont en regard. The arms 2 and 3 each have at their end, on their internal face, respectively 20 and 30, an adhesion zone, respectively 21 and 31, the adhesion zones 21 and 31 being brought into contact when, by pivoting the arm 3, arms 2 and 3 are facing each other.
Si on se réfère maintenant aux figures 3, on peut voir que dans un premler temps (figure 3a) un sachet 4, dont les deux côtés 40 et 41 ont tendance à adhérer et que l'on désire ouvrir, est positionné dans un plan vertical entre les deux bras 2 et 3. If we now refer to Figures 3, we can see that in a first time (Figure 3a) a bag 4, whose two sides 40 and 41 tend to adhere and which one wishes to open, is positioned in a vertical plane between the two arms 2 and 3.
Puis (figure 3b) en exerçant une pression P sur la poignée 32 du bras 3, celui-ci amorce un mouvement de cisaillement par rapport au bras 2, le côté 40 du sachet 4 adhérant à la zone d'adhérence 21 et le côté 41 à la zone d'adhérence 31. Then (FIG. 3b) by exerting a pressure P on the handle 32 of the arm 3, the latter initiates a shearing movement relative to the arm 2, the side 40 of the bag 4 adhering to the adhesion zone 21 and the side 41 to the grip zone 31.
En maintenant la pression P (figure 3c) les côtés 40 et 41 du sachet 4 restent solidarisés aux zones d'adhérence 21 et 31, et se séparent en créant des renflements 42 permettant à l'utilisateur d'ouvrir aisément le sachet 4. By maintaining the pressure P (FIG. 3c) the sides 40 and 41 of the bag 4 remain secured to the adhesion zones 21 and 31, and separate, creating bulges 42 allowing the user to easily open the bag 4.
