Description
La présente invention concerne un procédé de mise en place d'un tronçon de bande de thermoscellage au-dessus de récipients dans un carrousel de fermeture de récipients et un dispositif de mise en oeuvre de ce procédé.The present invention relates to a method of placing a section of heat-sealing strip over containers in a container closure carousel and a device for implementing this method.
On connait des installations de fermeture de récipients par thermoscellage d'un tronçon de bande, généralement un tronçon de bande composite comportant une couche de matière permettant de réaliser une soudure avec l'orifice d'un récipient et une couche formant une barrière contre les ultraviolets ou assurant une résistance mécanique du tronçon de bande mis en place sur l'orifice du récipient.There are known installations for closing containers by heat sealing a strip section, generally a composite strip section comprising a layer of material making it possible to weld with the orifice of a container and a layer forming a barrier against ultraviolet light. or ensuring mechanical strength of the strip section placed on the orifice of the container.
Dans ces installations le tronçon de bande thermoscellable est amené en porte à faux au-dessus de l'orifice d'un récipient puis une tête de thermoscellage est descendue pour effectuer la soudure du tronçon de bande. Un problème particulier se pose lorsque la bande thermoscellable n'a pas une rigidité suffisante pour que le tronçon de bande thermoscellable s'étende horizontalement au-dessus de l'orifice du récipient. Dans ce cas, le tronçon de bande tend à s'incurver vers le bas dès qu'il est mis en porte à faux et le simple frottement sur l'orifice supérieur du récipient provoque un plissement du tronçon de bande de sorte que le tronçon de bande ne recouvre pas totalement l'orifice du récipient au moment où la tête de thermoscellage est appliquée et la fermeture du récipient n'est donc pas assurée. Pour assurer un recouvrement convenable de l'orifice du récipient lorsque l'on utilise une bande de thermoscellage très fine présentant une faible rigidité, on a donc envisagé de mettre en place des dispositifs de préhension qui viennent saisir une extrémité de la bande et tirent celle-ci au-dessus de l'emplacement du récipient.In these installations, the section of heat-sealable strip is brought in a cantilever above the orifice of a container, then a heat-sealing head is lowered to effect the welding of the section of strip. A particular problem arises when the heat-sealable strip does not have sufficient rigidity so that the section of heat-sealable strip extends horizontally above the orifice of the container. In this case, the strip section tends to curve downwards as soon as it is cantilevered and the simple rubbing on the upper orifice of the container causes the strip section to crease so that the section of the strip does not completely cover the orifice of the container when the heat sealing head is applied and the closure of the container is therefore not ensured. To ensure adequate covering of the container orifice when using a very thin heat-sealing strip having a low rigidity, it has therefore been envisaged to put in place gripping devices which come to grip one end of the strip and pull that - above the location of the container.
De tels dispositifs sont complexes et entraînent une consommation plus importante de bande en raison de la partie de bande qu'il est nécessaire de prévoir pour assurer sa saisie par les moyens de préhension.Such devices are complex and lead to a higher consumption of tape due to the portion of tape that it is necessary to provide to ensure its gripping by the gripping means.
Selon l'invention, on propose un procédé de mise en place d'un tronçon de bande de thermoscellage au-dessus de récipients dans un carrousel de fermeture de récipients comportant une plate-forme rotative équipée d'organes de maintien de récipients disposés en-dessous de têtes de thermoscellage, cette plate-forme étant associée à un organe d'introduction de récipients et à un organe d'extraction de récipients, le procédé consistant à pousser un tronçon de bande de thermoscellage en porte à faux selon une direction d'introduction des récipients dans un secteur de la plate-forme disposé entre l'organe d'extraction de récipients et l'organe d'introduction de récipients par référence à un sens de rotation de la plate-forme.According to the invention, there is provided a method of placing a section of heat-sealing strip above containers in a container closing carousel comprising a rotary platform equipped with holding members for containers arranged in- below the heat-sealing heads, this platform being associated with a container introduction member and with a container extraction member, the method consisting in pushing a section of heat-seal strip cantilevered in a direction of introduction of the containers into a sector of the platform disposed between the container extraction member and the container introduction member with reference to a direction of rotation of the platform.
Ainsi, lorsqu'un récipient est introduit sur la plate-forme après l'avance du tronçon de bande, le récipient s'engage sous le tronçon de bande et tend à redresser celui-ci dans un sens ne risquant pas de provoquer un plissement du tronçon de bande de sorte que le tronçon de bande est disposé à plat sur l'orifice supérieur du récipient lorsque celui-ci est en place sur la plate-forme.Thus, when a container is introduced on the platform after the advance of the strip section, the container engages under the strip section and tends to straighten it in a direction not likely to cause wrinkling of the strip section so that the strip section is placed flat on the upper orifice of the container when the latter is in place on the platform.
Selon un autre aspect de l'invention, on prévoit un dispositif de mise en oeuvre du procédé comportant un organe d'avance de la bande de thermoscellage disposé pour pousser celle-ci selon une direction d'introduction des récipients et équipé d'un organe de sectionnement de bande, dans lequel l'organe d'avance de bande est monté pour pivoter autour d'un axe sensiblement horizontal et comporte un organe de relevage. Ainsi, au moment de l'introduction d'un récipient, l'organe d'avance de bande est légèrement relevé pour permettre le passage du récipient sans interférer avec l'organe de sectionnement de bande.According to another aspect of the invention, there is provided a device for implementing the method comprising a member for advancing the heat-sealing strip arranged to push the latter in a direction of introduction of the containers and equipped with a member strip cutting, in which the tape feed member is mounted to pivot about a substantially horizontal axis and comprises a lifting member. Thus, at the time of the introduction of a container, the tape advance member is slightly raised to allow the passage of the container without interfering with the tape sectioning member.

En référence à la figure 1, la bande de thermoscellage illustrée, généralement désignée en 1, comporte deux bords sensiblement rectilignes parallèles 2 entre lesquels sont réalisées des découpes 3 disposées dans la partie centrale de la bande.With reference to FIG. 1, the illustrated heat-sealing strip, generally designated at 1, comprises two substantially parallel
Chaque découpe comporte, par référence à un sens de déplacement de la bande, un bord avant ayant une partie centrale curviligne convexe 4 et deux parties extrêmes curvilignes concaves 5.Each cutout comprises, with reference to a direction of movement of the strip, a front edge having a convex curvilinear
En référence aux figures 3 à 5, le dispositif d'avance de bande comporte deux bras supports 6 reliés à des articulations 7 pour pivoter autour d'un axe sensiblement horizontal. Des organes de guidage 8 sont fixés aux bras supports 6 et s'étendent sous les bords latéraux de la bande. Un organe d'entraînement pas à pas, illustré par un rouleau 9 entraîné par un moteur pas à pas 10, est disposé en regard des organes de guidage 8 et comporte des plots d'entraînement cylindriques 11 s'étendant en saillie entre les organes de guidage et disposés pour s'engager dans les découpes 3 de la bande de thermoscellage.With reference to FIGS. 3 to 5, the tape advance device comprises two
Dans le mode de réalisation préféré illustré, les plots 11 ont un diamètre égal au rayon de courbure des parties de bord 5 des découpes 3 et ont une section droite inférieure à la partie des découpes dans lesquelles il s'engage. Le rouleau 9 est supporté par des goussets 12 fixés sur les côtés des bras supports 6. A son extrémité avant, le dispositif d'avance de bande comporte des ciseaux comprenant une lame inférieure 13 fixée à l'extrémité des bras supports 6 et une lame supérieure 14 portée par des bras 15 articulés autour d'axes 16 portés par les bras supports 6. Les ciseaux sont rappelés dans une position ouverte par un ressort 17, la course des bras 15 étant limitée par des butées 18 portées par les goussets 12.In the preferred embodiment illustrated, the
Le dispositif d'avance de bande est disposé à chaque poste d'un carrousel de fermeture de récipient illustré par la figure 2 comportant une plate-forme rotative 19 équipée d'encoches périphériques 20 formant des organes de maintien de récipient 21 qui sont introduits sur le carrousel par un organe d'introduction de récipient 22 et sont extraits de celui-ci par un organe d'extraction de récipient 23. Les dispositifs d'avance de bande sont solidaires de la plate-forme 19 et se déplacent donc en rotation avec celle-ci tout en restant constamment en regard d'une encoche 20.The tape advancement device is arranged at each station of a container closure carousel illustrated in FIG. 2 comprising a
Dans le mode de réalisation illustré, l'organe d'introduction de récipients 22 et l'organe d'extraction de récipients 23 sont constitués par des disques tangents à la plate-forme 19 de sorte que, compte tenu des mouvements relatifs de la plate-forme 19 et de l'organe d'introduction de récipients 22, les récipients 21 sont introduits sur la plate-forme 19 selon une courbe qui est tangente à un rayon de la plate-forme 19 comme illustré sur la figure 7 par une ligne en trait mixte et la flèche en trait épais qui lui est associée.In the illustrated embodiment, the
Selon l'invention, les dispositifs d'avance de bande sont disposés pour que le tronçon de bande 24 qui est poussé en porte à faux par le dispositif d'avance de bande soit également dirigé selon une direction radiale de la plate-forme 19. Selon le procédé de l'invention, le tronçon de bande 24 est avancé en porte à faux alors que le dispositif d'avance de bande se trouve dans le secteur compris entre l'organe d'extraction de récipients 23 et l'organe d'introduction de récipients 22 par référence à un sens de rotation de la plate-forme. Le tronçon de bande peut alors s'étendre librement en porte à faux puisqu'aucun récipient n'est disposé en-dessous du tronçon de bande. Ce procédé de mise en place de bande 24 est particulièrement utile lorsque la bande est très mince et n'a pas une rigidité suffisante pour s'étendre en porte à faux horizontalement mais a au contraire tendance à pendre au-delà de l'extrémité du dispositif d'avance de bande comme illustré sur la figure 3. Lorsqu'un récipient est introduit sur la plate-forme en suivant le mouvement illustré par la figure 6, ce récipient s'engage donc sous le tronçon de bande en porte à faux et selon une direction allant du dispositif d'avance de bande vers l'extrémité libre du tronçon de bande de sorte que le récipient tend à relever progressivement le tronçon de bande 24 comme illustré sur les figures 6 à 9 où le récipient a été illustré par un cercle symbolisant le bord supérieur de l'orifice. Au moment où le récipient est totalement engagé dans l'encoche de maintien 20, le tronçon de bande 24 est alors en appui sur le bord supérieur de l'orifice du récipient.According to the invention, the tape feeders are arranged so that the
Pour éviter que le récipient 21 ne vienne buter contre la lame inférieure 13 des ciseaux lors de l'introduction de ce récipient, le dispositif d'avance de bande est de préférence relevé au moment de l'introduction comme illustré par la figure 3, ce relevage étant par exemple réalisé au moyen d'une bielle 25 associée à un dispositif de commande non représenté qui est de préférence synchronisé avec les mouvements d'une tête de thermoscellage 26.To prevent the
Lorsque le récipient est totalement engagé dans l'encoche de maintien 20 avec le tronçon de bande 24 en appui sur le bord supérieur de l'orifice du récipient 21, le dispositif d'avance de bande est abaissé comme illustré sur la figure 4 pour que le bord supérieur de la lame inférieure 13 soit exactement dans le plan du bord supérieur du récipient 21, le tronçon de bande est ainsi en appui sur la totalité du pourtour de l'orifice du récipient. La tête de thermoscellage 26 est alors abaissée pour souder le tronçon de bande 24 sur l'orifice du récipient puis la lame supérieure 14 des ciseaux est abaissée pour sectionner le tronçon de bande.When the container is fully engaged in the
Comme illustré par la figure 4, l'abaissement de la lame supérieure 14 est de préférence provoquée par une came 27 fixée au bâti du carrousel de sorte que les ciseaux associés à un dispositif d'avance de bande sont actionnés chaque fois qu'ils passent en regard de la came 27.As illustrated in FIG. 4, the lowering of the
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and it is possible to make variant embodiments without departing from the scope of the invention as defined by the claims.
En particulier, bien que l'invention ait été décrite en liaison avec une bande de thermoscellage comportant des découpes dans la partie centrale de la bande et un dispositif d'avance de bande comportant des organes d'entraînement positif de la bande, le procédé selon l'invention peut également être mis en oeuvre avec une bande de thermoscellage ne comportant aucune découpe ou comportant des découpes latérales, et un dispositif d'avance de bande quelconque, par exemple un dispositif comportant des rouleaux d'entraînement lisses qui agissent sur la bande de thermoscellage par pincement.In particular, although the invention has been described in connection with a heat-sealing strip comprising cut-outs in the central part of the strip and a strip-advancing device comprising positive drive members for the strip, the method according to the invention can also be implemented with a heat-sealing strip having no cutout or comprising lateral cutouts, and any strip advance device, for example a device comprising smooth drive rollers which act on the strip pinch heat seal.
