Abstract

The method according to the invention consists: - in taking a protective cap (3) with the aid of a suction pad (20) associated with a cap piece (13a); - in applying the latter against the open edge of the container (30); - and in heating the assembly so that the said protective cap (3) thus centred is heat-welded (-sealed) to the said edge in a single operation without transfer of the container (30).

Description

La présente invention a trait aux machines permettant la fixation automatique des opercules de fermeture sur Le bord ouvert des récipients. The present invention relates to machines allowing the automatic fixing of the closure caps on the open edge of the containers.

On sait que les machines de ce type comprennent généralement un bâti pourvu d'un organe mobile et d'un distributeur d'opercules. L'organe mobile permet en premier lieu de saisir un opercule dans le distributeur, puis de Le déposer sur le bord ouvert d'un récipient. Ce dernier, muni de l'opercule de fermeture, est alors transféré à une autre machine qui réalise, par l'intermédiaire d'un inducteur, le soudage dudit opercule sur le récipient. It is known that machines of this type generally comprise a frame provided with a movable member and with a dispenser for lids. The movable member first allows to grasp a cover in the dispenser, then to deposit it on the open edge of a container. The latter, provided with the closure cap, is then transferred to another machine which performs, by means of an inductor, the welding of said cap on the container.

On conçoit que le transfert des récipients d'une machine à une autre comporte certains inconvénients en ce qui concerne la retenue de l'opercule sur Le bord ouvert, ce qui implique une vérification constante et fastidieuse desdits récipients. It is understood that the transfer of containers from one machine to another has certain drawbacks with regard to retaining the lid on the open edge, which implies a constant and tedious verification of said containers.

C'est à cet inconvénient qu'entend plus particulièrement remédier la présente invention, laquelle vise plus spécifiquement un procédé pour la fixation des opercules de fermeture sur le bord ouvert des récipients, ainsi qu'une machine pour sa mise en oeuvre. It is to this drawback that the present invention more particularly intends to remedy, which relates more specifically to a method for fixing the closure lids on the open edge of the containers, as well as a machine for its implementation.

Le procédé suivant L'invention se caractérise en ce qu'il consiste
- à prélever un opercule à L'aide d'une ventouse associée à une coiffe ;
- à appliquer cette dernière contre le bord ouvert du récipient ;
- et à chauffer l'ensemble de façon à ce que ledit opercule ainsi centré se trouve thermo-soudé audit bord en une seule opération, sans transfert du récipient.The process according to the invention is characterized in that it consists
- to take a seal using a suction cup associated with a cap;
- to apply the latter against the open edge of the container;
- And to heat the assembly so that said lid thus centered is heat-sealed to said edge in a single operation, without transferring the container.

Fig. 7 et 8 illustrent les deux dernières phases du processus de thermo-soudage. Fig. 7 and 8 illustrate the last two phases of the thermo-welding process.

On a représenté en fig. 1 la machine suivant L'invention permettant de déposer un opercule de fermeture sur le bord ouvert d'un récipient et de le fixer en place par thermo-soudage. There is shown in fig. 1 the machine according to the invention making it possible to deposit a closure cap on the open edge of a container and to fix it in place by heat welding.

Elle comprend un bâti 1 constitué d'une plaque supérieure la et d'une plaque inférieure lb reliées entre elle par deux parois latérales 1c et Id. It comprises a frame 1 consisting of an upper plate 1a and a lower plate 1b connected together by two side walls 1c and Id.

Sur la plaque supérieure la sont disposés, de façon à la traverser, d'une part un distributeur ou magasin 2 renfermant des opercules de fermeture 3 superposés, et d'autre part un vérin hydraulique ou pneumatique 4 dont l'utilisation sera exposée plus loin. On the upper plate 1a are arranged, so as to pass therethrough, on the one hand a distributor or magazine 2 containing closure caps 3 superimposed, and on the other hand a hydraulic or pneumatic cylinder 4 whose use will be explained later .

Sous la plaque supérieure la sont fixées par vissage deux colonnes 5 sur chacune desquelles coulissent deux guides 6 et 7. Les deux paires de guides 6 et 7 sont fixées sur les faces externes 8a et 9a de deux flasques latéraux 8 et 9 qui sont reliés entre eux par des entretoises de renfort 10 et 11. Under the upper plate 1a are fixed by screwing two columns 5 on each of which slide two guides 6 and 7. The two pairs of guides 6 and 7 are fixed on the external faces 8a and 9a of two lateral flanges 8 and 9 which are connected between them by reinforcing struts 10 and 11.

Comme représenté en fig. 2 et 3, un moyeu 12 est logé entre les flasques 8 et 9 et est pourvu d'un axe de pivotement 12a coopérant avec des alésages 8b et 9b ménagés dans lesdits flasques 8 et 9. Ce moyeu 12 est solidaire d'un organe mobile 13 qui comprend à son extrémité libre une coiffe 13a creusée d'un évidement 13b. De plus, sur L'axe de pivotement 12a du moyeu 12 est monté fou un pignon 14 qui engrène avec un pignon 15 entraîné par un moteur électrique représenté en M en fig. 1. As shown in fig. 2 and 3, a hub 12 is housed between the flanges 8 and 9 and is provided with a pivot axis 12a cooperating with bores 8b and 9b formed in said flanges 8 and 9. This hub 12 is integral with a movable member 13 which comprises at its free end a cap 13a hollowed out of a recess 13b. In addition, on the pivot axis 12a of the hub 12 is mounted for a pinion 14 which meshes with a pinion 15 driven by an electric motor shown in M in FIG. 1.

Le pignon fou 14 se trouve également en prise avec un autre pignon 16 qui est solidaire, par l'intermédiaire d'un arbre 16a, d'un pignon 17, lequel engrène avec une crémaillère 18 guidée en translation axiaLe dans le moyeu 12, prévu tubulaire à cet effet.The idler gear 14 is also engaged with another gear 16 which is secured, by means of a shaft 16a, to a gear 17, which meshes with a rack 18 guided in axial translation in the hub 12, provided tubular for this purpose.

La crémaillère 18 est solidaire d'un axe creux 19 qui coulisse axialement dans l'organe mobile 13 et qui comprend à son extrémité extérieure 19a une ventouse de prélèvement 20 commandée par un dispositif à aspiration d'air, schématisé en A en fig. 2. De plus, il est prévu un ressort de rappel 21 compris entre la face inférieure 12 du moyeu 12 et une butée 18a appartenant à la crémaiLLère 18. The rack 18 is integral with a hollow axis 19 which slides axially in the movable member 13 and which comprises at its outer end 19a a suction cup 20 controlled by an air suction device, shown schematically at A in fig. 2. In addition, a return spring 21 is provided, comprised between the lower face 12 of the hub 12 and a stop 18a belonging to the rack 18.

Le dispositif sus-décrit est destiné à impartir à L'organe mobile 13 associé au moyeu 12 une succession de rotations autour de l'axe de pivotement 12a, celles-ci étant limitées dans leurs course par portée contre des butées réglables 22, 23 ménagées à travers le flasque 8. The above-described device is intended to impart to the movable member 13 associated with the hub 12 a succession of rotations around the pivot axis 12a, these being limited in their travel by bearing against adjustable stops 22, 23 formed through the flange 8.

Il est de même prévu entre les plaques supérieure la et inférieure lb et les parois Latérales lc, ld, un coffret d'alimentation électrique 24 solidaire d'un support 25 équipé de quatre manchons 25a, 25b, 25c, 25d qui coopèrent avec deux colonnes 26 fixées dans Les plaques la et lb. Cet ensemble est maintenu sur les colonnes 26 à une hauteur déterminée par l'intermédiaire de ressorts 27, 28 disposés entre Les manchons 25a et 25b et la plaque inférieure lb (fig. 1). It is likewise provided between the upper plates 1a and 1b and the side walls lc, ld, an electrical supply box 24 secured to a support 25 equipped with four sleeves 25a, 25b, 25c, 25d which cooperate with two columns 26 fixed in Plates 1a and 1b. This assembly is held on the columns 26 at a height determined by means of springs 27, 28 arranged between the sleeves 25a and 25b and the lower plate lb (fig. 1).

Le coffret d'alimentation électrique 24 comporte un inducteur 29 en forme de boucle, de sorte qu'il entoure au moment du thermo-soudage La coiffe 13a de L'organe mobile 13, comme on l'exposera plus loin. The electrical supply box 24 includes an inductor 29 in the form of a loop, so that it surrounds the cap 13a of the movable member 13 at the time of heat welding, as will be explained below.

En outre, l'organe mobile 13 porté par Les flasques latéraux 8 et 9 coulisse verticalement sur les colonnes 5 sous L'action du vérin 4 dont l'embout de la tige coopère avec l'entretoise de renfort 11, permettant ainsi, grâce à La conformation de L'un des guides 6, d'entraîner vers le bas le coffret d'alimentation électrique 24 le Long des colonnes 26. In addition, the movable member 13 carried by the lateral flanges 8 and 9 slides vertically on the columns 5 under the action of the jack 4 whose end piece of the rod cooperates with the reinforcing spacer 11, thus allowing, thanks to The conformation of one of the guides 6, to drive down the power supply cabinet 24 along the columns 26.

On a représenté en fig. 4 à 8 les phases successives qui permettent la fixation d'un opercule 3 sur le bord ouvert d'un récipient 30. Le processus est le suivant :
- Le moteur M fait tourner le pignon 15 dans le sens inverse des aiguilles d'une montre alors que L'organe mobile 13 est tourné vers le haut et que le moyeu 12 porte contre la butée 22 (fig. 4). Dans ces conditions, le pignon 17 entraîne la crémaillère 18 vers le haut, de sorte que d'une part le ressort de rappel 21 se comprime et que d'autre part L'axe 19 amène la ventouse de prélèvement 20 contre L'opercule inférieur 3 du distributeur 2.There is shown in fig. 4 to 8 the successive phases which allow the fixing of a cover 3 on the open edge of a container 30. The process is as follows:
- The motor M rotates the pinion 15 anticlockwise while the movable member 13 is turned upwards and the hub 12 bears against the stop 22 (fig. 4). Under these conditions, the pinion 17 drives the rack 18 upwards, so that on the one hand the return spring 21 is compressed and that on the other hand the axis 19 brings the suction cup 20 against the lower cover. 3 from dispenser 2.

- L'aspiration plaque la ventouse 20 contre l'opercule 3 à la suite de L'actionnement du dispositif A (fig. 4). - The suction presses the suction cup 20 against the cover 3 following the actuation of the device A (fig. 4).

- Le moteur M étant alors arrêté, la rotation du pignon 15 cesse, ce qui provoque la descente de la crémaillère 18 sous l'effet du ressort de rappel 21, si bien que l'opercule 3 vient en contact du fond de l'évidement 13b de la coiffe 13a de L'organe mobile 13 (fig. 5). - The motor M is then stopped, the rotation of the pinion 15 ceases, which causes the rack 18 to descend under the effect of the return spring 21, so that the cover 3 comes into contact with the bottom of the recess 13b of the cap 13a of the movable member 13 (fig. 5).

- Le moteur M entraîne alors le pignon 15 dans le sens des aiguilles d'une montre, afin que l'organe mobile 13 solidaire du moyeu 12 pivote autour de l'axe de rotation 12a, jusqu'à ce que ledit moyeu 12 rencontre la butée de fin de course 23, la coiffe 13a dudit organe mobile 13 se trouve alors au-dessus de l'inducteur 29 (fig. 6). - The motor M then drives the pinion 15 clockwise, so that the movable member 13 secured to the hub 12 pivots about the axis of rotation 12a, until said hub 12 meets the end of travel stop 23, the cover 13a of said movable member 13 is then located above the inductor 29 (FIG. 6).

- Le vérin hydraulique 4 est alimenté, ce qui provoque dans un premier temps la descente de l'organe mobile 13 jusqu'à ce que La coiffe 13a se trouve entourée par L'inducteur 29 et, dans un second temps, la descente synchronisée de L'organe 13 et du coffret d'alimentation électrique 24 par l'intermédiaire de l'un des guides 6 jusqu'à ce que le bord ouvert du récipient 30 soit centré dans l'évidement 13b de la coiffe 13a (fig. 7). - The hydraulic cylinder 4 is supplied, which initially causes the mobile member 13 to descend until the cap 13a is surrounded by the inductor 29 and, in a second step, the synchronized descent of The member 13 and the electrical supply box 24 via one of the guides 6 until the open edge of the container 30 is centered in the recess 13b of the cap 13a (fig. 7) .

- Le coffret 24 assure L'alimentation de L'inducteur 29, si bien que par induction, l'opercule 3 est chauffé en vue de son soudage sur le bord du récipient 30 (fig. 7). - The box 24 ensures the supply of the inductor 29, so that by induction, the cover 3 is heated for welding on the edge of the container 30 (fig. 7).

- La tige du vérin hydraulique 4 est remontée afin de dégager le récipient 30 de la coiffe 13a, ce qui libère verticalement le coffret d'alimentation électrique 24 qui reprend sa position initiale sous l'effet des ressorts 27 et 28 (fig. 8). - The rod of the hydraulic cylinder 4 is raised in order to free the container 30 from the cover 13a, which releases the electrical power supply box 24 vertically which returns to its initial position under the effect of the springs 27 and 28 (fig. 8) .

- Le pignon 15 est entraîné dans Le sens inverse des aiguilles d'une montre pour remonter L'organe mobile 13 à sa position initiale, de manière à ce que le moyeu 12 vienne en contact avec La butée de fin de course 22 (fig. 8). - The pinion 15 is driven anticlockwise to raise the movable member 13 to its initial position, so that the hub 12 comes into contact with the end stop 22 (fig. 8).

- Un nouveau récipient 30 est amené pour que le cycle de fixation d'un opercule 3 puisse recommencer. - A new container 30 is brought in so that the cycle for fixing a cover 3 can start again.

On peut vérifier que L'ensemble du processus de fixation de l'orpercule sur le récipient ne nécessite aucun déplacement de ce dernier. We can verify that the whole process of fixing the orpercule on the container does not require any displacement of the latter.

Il va de soi que le vérin 4 pour le déplacement vertical de l'organe mobile 13 et du coffret 24 est susceptible d'être remplacé par un système mécanique à came ou à crémaillère. IL en va de même pour le moteur M qui peut prendre la forme d'un vérin rotatif. En certain cas, une résistance électrique de chauffage peut être directement incorporée à La coiffe 13a en dispensant ainsi de la présense de L'inducteur 29 et du coffret 24. It goes without saying that the jack 4 for the vertical displacement of the movable member 13 and of the box 24 is capable of being replaced by a mechanical cam or rack system. The same goes for the motor M which can take the form of a rotary actuator. In some cases, an electrical heating resistor can be directly incorporated into the cap 13a, thereby dispensing with the presence of the inductor 29 and the box 24.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de L'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
