Description
Procédé de fixation d'un élément tel qu'un bouton sur un tissu, bouton et appareil de fixation pour la mise en oeuvre de ce procédé. Method of fixing an element such as a button on a fabric, button and fastening apparatus for carrying out this method
La présente invention concerne un procédé de fixation d'élé ment s tels que des boutons sur un matériau textile, le bouton comprenant une première tête destinée à être positionnée d'un c#té du tissu, et une tige devant traverser le tissu et être munie à son extrémité opposée d'une seconde tête destinée à être positionnée sur le second côté du tissu. L'invention concerne également un appareil pour la fixation de tels boutons sur les tissus. The present invention relates to a method of fixing elements such as buttons on a textile material, the button comprising a first head intended to be positioned on one side of the fabric, and a rod to pass through the fabric and to be provided at its opposite end with a second head to be positioned on the second side of the fabric. The invention also relates to an apparatus for fixing such buttons on the tissues.
On connaît des boutons dont la fixation sur des tissus, en particulier des vêtements, s'effectue rapidement, sans fil, par adjonction d'un pic traversant le tissu et se fixant au bouton. La fixation du pic et du bouton est généralement réalisée par collage au moyen d'un apport de colle ou de solvant sur les surfaces en contact.D'autres dispositifs prévoient le chauffage partiel du pic ou du bouton ou l'application d'ultrasons, provoquant le ramollissement des matières plastiques constituant ces éléments et le soudage de celles-ci l'une sur l'autre. De telles dispositions comportent des in convénients parmi lesquels on peut notamment citer la diffi culté de réalisation et de montage, la solidité aléatoire de la liaison du bouton au pic de fixation, et la déformation possible du bouton sous l'effet de la chaleur lors du montage.De plus il apparat que dans les dispositifs connus le soudage par ultrasons est utilisé de la même façon que les autres modes de chauffage ou de ramollissement de ma tièdes plastiques9 sans tenir compte des aspects spécifiques de la présente des ultrasons. Knobs are known whose attachment to fabrics, especially clothes, is carried out quickly, wireless, by adding a peak through the fabric and attaching to the button. The fixation of the peak and the button is generally carried out by gluing by means of a glue or solvent supply on the surfaces in contact. Other devices provide for the partial heating of the peak or the button or the application of ultrasound. causing the softening of the plastics constituting these elements and the welding thereof to one another. Such arrangements include disadvantages among which we can notably mention the difficulty of implementation and assembly, the random strength of the connection of the button to the peak of fixation, and the possible deformation of the button under the effect of heat during the Moreover, it appears that in known devices ultrasonic welding is used in the same way as the other modes of heating or softening my warm plastics9 without taking into account the specific aspects of the present ultrasound.
En outre, dans ces méthodes connues, le perçage du tissu par la tige ou le pic s'effectue par enfoncement de ce pic dans le tissu par application d'une force sur la tête du pic. In addition, in these known methods, the piercing of the tissue by the stem or the peak is effected by driving this peak into the tissue by applying a force to the head of the peak.
Pour Faciliter la pénétration, le pic comporte une extrémité pointue, cette pointe ayant pour objet d'écarter les fibres du tissu lors de la razpE5l6trationo Néanmoins, malgré cette ex trémité pointue, certaines fibres du tissu sont coupées lors de la pénétration de la pointe et éventuellement entraînées avec la tige. Le tissu est ainsi localement détérioré, ce qui, suivant la qualité de ce tissu, peut présenter des inconvénients graves. D'autre part, les fibres entraînées avec la tige risquent de se trouver collées ou soudées en même temps que la tige et le bouton, ce qui rend très difficile le changement ou le remplacement ultérieur du bouton.To facilitate penetration, the peak has a pointed end, this point having for object to remove the fibers of the fabric during the razpE5l6trationo Nevertheless, despite this pointed end, some fibers of the fabric are cut during the penetration of the tip and possibly driven with the rod. The fabric is thus locally deteriorated, which, depending on the quality of this fabric, can have serious disadvantages. On the other hand, the fibers entrained with the rod may be glued or welded together with the rod and the button, which makes it very difficult to change or replace the button later.
Un objet de la présente invention est de proposer des moyens particuliers pour le perçage du tissu et la formation de la tête au bout de la tige dans le cas où l'on emploie des ultrasons. An object of the present invention is to provide particular means for piercing the tissue and forming the head at the end of the stem in the case where ultrasound is used.
Un autre objet de la présente invention est d'obvier aux inconvénients des dispositifs antérieurs en proposant un procédé de perçage de tissu et de fixation de bouton qui évite la destruction et la coupure des fibres du tissu. Another object of the present invention is to overcome the disadvantages of the prior art devices by providing a method of fabric piercing and button fixation which avoids the destruction and cutting of the fibers of the fabric.
Un autre objet de la présente invention est de proposer un bouton et un dispositif pour la fixation de ce bouton qui permettent une fixation rapide et solide par ultrasons. Another object of the present invention is to provide a button and a device for fixing this button which allow a fast and solid fixation by ultrasound.
Pour ce faire et selon une caractéristique de la présente invention, le bouton comprend une préforme constituée d'une première tête destinée à être positionnée sur un premier cOté du tissu et solidaire d'une tige en matière plastique devant percer le tissu, devant s'étendre au moins en partie à travers ce tissu et être munie à son extrémité opposée par application d'un outil soumis à des vibrations ultrasoniques d'une seconde tête destinée à être positionnée sur le second cOté du tissu, le perçage et la pénétration de la tige à travers le tissu étant réalisés en appliquant sur la première tête une poussée dans l'axe de la tige au moyen du même outil soumis à une force de pression modulée par des oscillations ultrasoniques de sorte que la tige pénètre en vibrant dans le tissu par son extrémité opposée à la première tête. To do this and according to a feature of the present invention, the button comprises a preform consisting of a first head intended to be positioned on a first side of the fabric and secured to a plastic rod to pierce the fabric, before s' extend at least partially through this tissue and be provided at its opposite end by applying a tool subjected to ultrasonic vibrations of a second head to be positioned on the second side of the tissue, drilling and penetration of the rod through the fabric being made by applying to the first head a thrust in the axis of the rod by means of the same tool subjected to a pressure force modulated by ultrasonic oscillations so that the rod penetrates by vibrating into the tissue by its opposite end to the first head.
Selon une autre caractéristique de la présente invention, le formage de la seconde tête est réalisé par application sur la première tête de l'outil soumis à une force de pression modulée par des oscillations ultrasoniques, l'extrémité de la tige étant appuyée contre un support fixe de telle façon que la matière plastique de l'extrémité de la tige en fondant forme la seconde tête. According to another characteristic of the present invention, the forming of the second head is carried out by application to the first head of the tool subjected to a pressure force modulated by ultrasonic oscillations, the end of the rod being pressed against a support fixed so that the plastic material of the end of the stem melting forms the second head.
Selon une autre caractéristique de la présente invention, le formage de la seconde tête est réalisé par application sur la première tête de l'outil soumis à une force de pression modulée par des oscillations ultrasoniques, l'extrémité de la tige étant appuyée sur une tête préformée maintenue sur un support fixe et comportant en vis à vis de la tige une surface de contact en même matière plastique que la tige de sorte que la matière plastique de l'extrémité de la tige en fondant produise le soudage de la tige et de la seconde tête. According to another characteristic of the present invention, the forming of the second head is carried out by application to the first head of the tool subjected to a pressure force modulated by ultrasonic oscillations, the end of the rod being supported on a head preformed on a fixed support and having opposite the rod a contact surface of the same plastic material as the rod so that the plastic material of the end of the rod by melting produces the welding of the rod and the second head.
Selon une autre caractéristique de la présente invention, le bouton comprend une première tête so##lidaire d'une tige dont l'extrémité libre est pointue, la zone de la pointe comportant des nervures longitudinales. According to another characteristic of the present invention, the button comprises a first head so ## lidaire a rod whose free end is pointed, the tip area having longitudinal ribs.
Selon une autre caractéristique de la présente invention, la seconde tête préformée comporte un trou borgne à fond sensiblement plan et de diamètre légèrement supérieur à la section de la tige, le rebord du trou formant une protubérance dépassant de la tête. According to another characteristic of the present invention, the second preformed head comprises a blind hole with a substantially planar bottom and a diameter slightly greater than the section of the rod, the rim of the hole forming a protrusion protruding from the head.
Selon une autre caractéristique de la présente invention, le dispositif de fixation du bouton selon la présente invention comporte un support fixe destiné à maintenir la seconde tête, un outil vibrant mobile par translation et soumis à l'action d'un organe vibreur, l'outil étant appliqué sur la première tête du bouton, un dispositif d'amenée de la préforme, et un dispositif de maintien latéral de la préforme lors de sa translation et du perçage du tissu. According to another characteristic of the present invention, the button fixing device according to the present invention comprises a fixed support intended to hold the second head, a vibrating tool movable by translation and subjected to the action of a vibrating member, the tool being applied to the first head of the button, a feed device of the preform, and a lateral holding device of the preform during its translation and piercing of the fabric.

Comme le représentent en coupe longitudinale les figures 1, 2 et 3, la présente invention prévoit un bouton comportant une première tête 1 solidaire d'une tige en matière plastique 2 et une seconde tête préformée 3. La fixation du bouton est réalisée par perçage du tissu et assemblage de la tige 2 et de la seconde tête -3. La seconde tête 3 est maintenue-fixe sur un support fixe 4 et comporte au moins une portion en matière plastique destinée à entrer en contact avec l'extrémité de la tige 2 après le perçage du tissu. La tige 2 et la première tête 1 sont maintenues en position par une pince 5. Un outil 6 est appliqué contre la première tête 1 et exerce sur cette tête une poussée selon l'axe de la tige 2-dans la# direction de la seconde tête 3, cette direction étant schématisée par la flèche 7.L'outil 6 est en outre soumis à des oscillations ultrasoniques longitudinales, ce mouvement étant schématisé par la flèche 8, de sorte que la pression exercée par ltou- til sur la tête 1 est modulée par les oscillations# ultrasoniques. Le tissu 9 est engagé entre l'extrémité libre 10 de la tige 2 et la seconde tête 3. As shown in longitudinal section in Figures 1, 2 and 3, the present invention provides a button having a first head 1 secured to a plastic rod 2 and a second preformed head 3. The button is fastened by drilling the fabric and assembly of the rod 2 and the second head -3. The second head 3 is held-fixed on a fixed support 4 and comprises at least a plastic portion intended to come into contact with the end of the rod 2 after the piercing of the fabric. The rod 2 and the first head 1 are held in position by a gripper 5. A tool 6 is applied against the first head 1 and exerts on this head a thrust along the axis of the rod 2 in the direction of the second 3, this direction being shown schematically by the arrow 7.The tool 6 is also subjected to longitudinal ultrasonic oscillations, this movement being shown schematically by the arrow 8, so that the pressure exerted by the nozzle on the head 1 is modulated by ultrasonic oscillations. The fabric 9 is engaged between the free end 10 of the rod 2 and the second head 3.
Dans une première phase, l'ensemble constitué par la tige 2, la première tête 1, la pince 5 et l'outil 6 est animé d'un mouvement de translation dans le sens de la flèche 7. Sous l'action conjuguée de la pression dans le sens de la flèche 7 et des oscillations ultrasoniques 8, la tige pénètre & travers le tissu 9 et vient en contact avec la seconde tête 3 comme le représente la figure 2. Sous l'action des oscillations ultrasoniques, l'extrémité 10 de la tige-2 s'échauffe et fond, provoquant également I' échauffement de la partie correspondante de la seconde tête 3, de sorte que la soudure entre la tige 2 et la tête 3 est réalisée. L'outil 6 est ensuite retiré comme le représente la figure 3, la première tête 1 étant positionnée sur le premier côté du tissu, et la seconde tête 3 étant positionnée sur le second cOté du tissu. In a first phase, the assembly consisting of the rod 2, the first head 1, the clamp 5 and the tool 6 is driven in a translational movement in the direction of the arrow 7. Under the combined action of the pressure in the direction of the arrow 7 and ultrasonic oscillations 8, the rod penetrates through the fabric 9 and comes into contact with the second head 3 as shown in Figure 2. Under the action of ultrasonic oscillations, the end 10 the rod-2 heats up and melts, also causing the heating of the corresponding portion of the second head 3, so that the welding between the rod 2 and the head 3 is performed. The tool 6 is then removed as shown in FIG. 3, the first head 1 being positioned on the first side of the fabric, and the second head 3 being positioned on the second side of the fabric.
Une variante de ce procédé est décrite en relation avec les figures 4, 5 et 6 sur lesquelles la seconde tête 3 est formée par fusion et déformation de l'extrémité 10 de la tige 2. A variant of this method is described in relation to FIGS. 4, 5 and 6 on which the second head 3 is formed by melting and deformation of the end 10 of the rod 2.
Comme précédemment la première étape consiste à déplacer par translation l'ensemble de l'outil 6, de la première tête 1 et de la tige 2 et de la pince 5 dans le sens de la flèche 7 de sorte que l'extrémité 10 de la tige pénètre dans le tissu 9.As previously, the first step consists in translating the assembly of the tool 6, the first head 1 and the rod 2 and the clamp 5 in the direction of the arrow 7 so that the end 10 of the stem penetrates the tissue 9.
Les oscillations ultrasoniques appliquées par l'outil 6 et schématiquement représentées par la flèche 8 facilitent le perçage du tissu. Dans la seconde phase l'extrémité 10 de la tige 2 vient en contact avec le fond d'un logement 40 ménagé à la surface du support fixe 4. Sous l'action des oscillations 8, l'extrémité 10 de la tige fond et tend & occuper l'ensemble du logement 40, formant ainsi la seconde tête 3 comme représenté à la figure 6. L'outil 6 est ensuite retiré, l'opération de fixation du bouton étant terminée.The ultrasonic oscillations applied by the tool 6 and schematically represented by the arrow 8 facilitate the piercing of the tissue. In the second phase the end 10 of the rod 2 comes into contact with the bottom of a housing 40 formed on the surface of the fixed support 4. Under the action of the oscillations 8, the end 10 of the rod melts and tends & occupy the entire housing 40, thereby forming the second head 3 as shown in Figure 6. The tool 6 is then removed, the button fixing operation being completed.
L'opération de perçage du tissu telle que décrite précédem ment est facilitée lorsque la tige 2 est conformée de la façon suivante décrite en relation avec les figures 7 et 8. Dans ce mode de réalisation, la tige 2, solidaire de la tête 1, a une extrémité libre 10 pointue. Les opérations de soudage par ul trasons nécessitent d'avoir une pointe 10 suffisasment solide pour ne pas plier au début de l'échauffement ce qui peut être réalisé en prévoyant une pointe conique dont le cône est très ouverts Cependant, dans l'opération de perçage du tissu, l'o giration de perçage est facilitée par une pointe conique dont le c6ne est très fermé, la pointe étant alors profilée pour pi trier plus facilement. Ces exigences sont contradictoires et la présente invention prévoit une conformation de tige permettant à la fois une soliditF de la pointe et une bonne p6- nétration a travers le tissu. il est prévu pour cela de munir la tige 2 d'vue extrémité pointue 10 comportant des nervures longitudinales telles que 70. Sur les figures 7 et 8 on a représenté une telle tige munie de quatre rainures réparties sur le pourtour de la pointe, de sorte que la résistance au flambage de la pointe est améliorée tandis que sa section se trouve diminuée pour faciliter la pénétration dans le tissu. The operation of drilling the fabric as described above is facilitated when the rod 2 is shaped as described below in relation to FIGS. 7 and 8. In this embodiment, the rod 2, integral with the head 1, has a sharp free end. The ultrasonic welding operations require to have a tip 10 sufficiently solid not to bend at the beginning of the heating which can be achieved by providing a conical tip whose cone is very open However, in the drilling operation From the fabric, the drilling angle is facilitated by a conical tip whose cone is very closed, the tip being then profiled to p sort more easily. These requirements are contradictory and the present invention provides a rod conformation allowing both tip strength and good penetration through the tissue. it is intended for this purpose to provide the rod 2 pointed end view 10 having longitudinal ribs such as 70. In Figures 7 and 8 there is shown such a rod provided with four grooves distributed around the periphery of the tip, so that the buckling resistance of the tip is improved while its section is decreased to facilitate penetration into the tissue.
Dans le mode de réalisation utilisant une seconde tête 3 préformée, la présente invention prévoit que cette seconde tête comporte au moins une zone en matière plastique pour permettre le soudage avec la matière plastique de la tige 2. In the embodiment using a second preformed head 3, the present invention provides that this second head comprises at least one plastic zone to allow welding with the plastic material of the rod 2.
Comme le représente la figure 9, selon un premier mode de réalisation, cette seconde tête 3 est entièrement constituée en matière plastique et comporte sur sa face destinée au soudage un cOllet central cylindrique formant protubérance 90 percé d'un alésage axial borgne 91 ouvrant sur la base 92 de ce collet.
