Abstract

At the welding station of a packaging machine, a gas is injected through the packaging film under a total or partial vacuum. A passage (H) at the frame (E) or other section of the welding station, is for the movement of the packaging film (G). It is totally sealed by an inflatable rubber tube (I), or other similar flexible seal. The gas is passed into the packages or pastry boats (M) by injection or inhalation, using jets, injectors or dosing units (J) within the frame (E), using fluids, liquid products, semi-liquids, pastes or viscous materials, designed to give a controlled atmosphere within the package within the welding station. The pastry boats can be refilled, in a swing to the edge or the whole of the heat molding, if necessary by an initial welding to be refilled by injection or inhalation. In a heat molding or package sealing system, the injection of the replacement inner atmosphere is up to \!10% film loss, directly at the welding station.

Description

DESCRIPTIF
Actuellement la plupart des produits, plus particulièrement les produits alimentaires, sont conditionnés dans des emballage ou des barquettes, operculées bénéficiant ou pas d'un traitement, sous atmosphère controlée, tel que vide ou réinjection de gaz, Cette opération se réalisant, d'ailleurs, aussitôt après le remplissage de la barquette, pour les produits nécéssitant un tel traitement.DESCRIPTION
Currently most products, more particularly food products, are packaged in packaging or trays, sealed benefiting or not from a treatment, under controlled atmosphere, such as vacuum or gas reinjection, This operation being carried out, moreover , immediately after filling the tray, for products requiring such treatment.

La présente invention concerne un dispositif destiné à osbstruér et rendre totalement étanche un passage pratiqué dans le cadre d'un poste de soudage d'une machine de conditionnement, mais plus particulièrement une thermoformeuse ou une operculeuse, dans et par lequel vient glisser le film qui doit venir operculer la barquette, permettant d'obtenir, ainsi, une étanchéité parfaite à l'intérieur du poste de soudage et de réaliser certaines opérations soit de réinjection de gaz ou de remplissage, grace à l'étanchéité et au vide parfaits ainsi obtenus
Selon l'une des caractéristiques du dispositif, la présente invention à pour but, après l'obstruction du passage du film pour réaliser l'étanchéité et la mise sous atmosphère controlée.dans le poste de soudage, la réinjection d'un gaz à l'intérieur de la barquette.The present invention relates to a device intended to seal and completely seal a passage made in the context of a welding station of a packaging machine, but more particularly a thermoforming machine or a sealer, into and through which the film which slides must seal the tray, thus obtaining a perfect seal inside the welding station and performing certain operations, either gas reinjection or filling, thanks to the perfect seal and vacuum thus obtained
According to one of the characteristics of the device, the present invention aims, after obstructing the passage of the film to achieve sealing and placing under a controlled atmosphere. In the welding station, the reinjection of a gas at l inside the tray.

Selon 1' une des autres caractéristiques du dispositif
la présente invention à pour objet de réaliser, par mesure d'hygiène le remplissage d' emballages ou de barquettes, aussitôt après et durant leur mise
sous tmosphère controlée, par certains produits pouvant être injectés
ou dosés tels que:
liquides, plus ou moins visqueux ou pâteux, leur évitant ainsi tous problèmes de pollution par l'air ambiant et les agents extérieurs, puisque n'ayant plus
aucun contact avec l'atmosphère extérieure, leur assurant ainsi une
meilleure conservation, protection et hygiène.According to one of the other characteristics of the device
the object of the present invention is to provide, for hygienic reasons, the filling of packages or trays, immediately after and during their placing.
under controlled atmosphere, by certain products that can be injected
or dosed such as:
liquids, more or less viscous or pasty, thus preventing them from any problems of pollution by ambient air and external agents, since they no longer have
no contact with the outside atmosphere, thus ensuring
better conservation, protection and hygiene.

Suivant une autre caractéristique de ce dispositif, il est désormais possible de remplir les emballages ou barquettes avec des produits liquides ou semi liquides ou visqueux de plus ou moins forte densité, sous ( ou pas) atmosphère controlée, jusqu'à ras le bord, si nécessaire, sans risque de débordement au remplissage, puisque la barquette peut être déja, si nécessaire, avant le remplissage, dans le poste de soudure, pratiquement operculée, laissant juste le passage, dans la barquette, de doseurs, injecteurs ou tout autre système pour son remplissage, adaptés dans le cadre ou toute autre partie du poste de soudure, et éventuellement des passages d'échappements, dans l'operculage, pour le cas ou le vide ne serait pas requis . According to another characteristic of this device, it is now possible to fill the packages or trays with liquid or semi-liquid or viscous products of varying density, under (or not) controlled atmosphere, to the brim, if necessary, without risk of overflow during filling, since the tray can be already, if necessary, before filling, in the welding station, practically sealed, leaving just the passage, in the tray, of dosers, injectors or any other system for its filling, adapted as part or any other part of the welding station, and possibly exhaust passages, in the sealing, in case the vacuum is not required.

Cette opération de remplissage, à ras le bord, avec des produits liquides, visqueux ou pâteux pouvant se faire, si nécessaire, en plusieurs temps ou opérations sur une operculeuse ou thermoformeuse, tout d'abord, une première soudure partielle du film sur la barquette, ne laissant de passage que pour les becs d'un appareil, injecteur ou doseur, alors que cette derniere est déja mise sous atmosphère controlée, grace, entre autres, à l' étanchéité obtenue par l'oburation du passage du film, dans le cadre du poste de soudure. This filling operation, to the brim, with liquid, viscous or pasty products which can be done, if necessary, in several stages or operations on a sealer or thermoformer, first of all, a first partial sealing of the film on the tray , leaving passage only for the spouts of a device, injector or doser, while the latter is already placed under a controlled atmosphere, thanks, among other things, to the seal obtained by sealing the passage of the film, in the part of the welding station.

Ensuite, le remplissage de la barquette par l'intermédiaire des becs des doseurs ou de tout autre système..  Then, the filling of the tray through the spouts of the dispensers or any other system.

Enfin, une fois cette dernière remplie, alors que les becs du ou des doseurs, ou de tout autre système, libérant totalement le plan de soudure, en se dégageant ou se retranctant ou part tout autre façon, moyen ou système, l'operculage ou la soudure définitive de tous les passages de la barquette s'effectue, réalisant ainsi un remplissage de la barquette complet, à ras le bord. Finally, once the latter is filled, while the spouts of the metering device (s), or of any other system, completely releasing the welding plane, by disengaging or cutting off or leaving in any other way, means or system, the sealing or the final sealing of all the passages of the tray is carried out, thus filling the tray completely, to the brim.

Par ailleurs, si l'on désire remplir la barquette, quasiment déja operculée, sans faire le vide, il est alors nécessaire, en plus des passages pratiqués pour les doseurs ou injecteurs etc.. dans une quelconque partie du poste
de soudure, de prévoir un ou plusieurs passages pour laisser s'échapper l'air
confiné dans la barquette lors de ce remplissage.Furthermore, if one wishes to fill the container, almost already sealed, without creating a vacuum, it is then necessary, in addition to the passages made for the metering or injectors, etc. in any part of the station.
welding, provide one or more passages to let air escape
confined in the tray during filling.

S'il n'est pas requis de remplir la barquette ou l'emballage à ras le bord, avec les doseurs, tout en bénéficiant ou pas d'une mise sous atmosphère controlée,
pour éviter toute pollution et si le produit le nécéssite, il est possible de lui injecter un gaz par des injecteurs, insérés également soit dans le cadre ou toute autre partie du poste de soudure. pour une meilleure conservation du produit conditionné.If it is not necessary to fill the tray or packaging to the brim, with the dosers, while benefiting or not from a controlled atmosphere setting,
to avoid any pollution and if the product requires it, it is possible to inject a gas through injectors, also inserted either in the frame or any other part of the welding station. for better conservation of the packaged product.

D'autres caractéristiques, explications et avantages de la présente invention apparaîtront au cours de la description suivante donnée en regard des dessins annexés à titre illustratif mais nullement limitatifs dans lesquels:
Les figures 1 et 2 représentent en coupe le Poste de soudage, sur une machine de conditionnement, plus particulièrement une thermoformeuse ou une operculeuse.Other characteristics, explanations and advantages of the present invention will appear during the following description given with reference to the drawings annexed by way of illustration but in no way limitative in which:
Figures 1 and 2 show in section the welding station, on a packaging machine, more particularly a thermoforming machine or a sealer.

Le film G d'operculage, introduit par un passage H dans le cadre E du poste de soudage D, recouvre la barquette M positionnée dans le moule L du poste de soudure, déja précédemment remplie de son produit P.avant que le Piston B du
verin A ne vienne plaquer et souder par l'intermédiaire de la plaque de soudure chauffante F le film G sur les bords de la barquette M reposant sur les joints K du moule L.The sealing film G, introduced through a passage H in the frame E of the welding station D, covers the tray M positioned in the mold L of the welding station, already previously filled with its product P. before the piston B of the
cylinder A does not come to press and weld through the hot soldering plate F the film G on the edges of the tray M resting on the joints K of the mold L.

S'il est nécessaire de réinjecter un fluide tel qu'un Gaz neutre, pour une meilleure conservation, cette opération se déroule tout simplement alors que, dans le cas présent, la membrane du tube caoutchouc I inseré dans le cadre E du poste
de soudage est gonflée bloquant le film G et obstruant totalement le passage H sur
toute sa largeur, I'on injecte par le circuit de Fluide J pratiqué dans le cadre E le gaz qui pénêtre dan la barquette M, cette opération se réalisant alors que tout l'ensemble est totalement étanche: En effet le moule L est venu se plaquer contre le bas du cadre E de l'outillage D, le passage du film H étant lui-même totalement
étanche car obstrué, dans le cas présent, par un tube I caoutchouc gonflable à l'air ou tout autre fluide., mais pouvant être obstrué par tout autre système et aussi bien dessus que dessous le film ainsi que présenté dans la figure N"2. If it is necessary to reinject a fluid such as a neutral gas, for better conservation, this operation takes place simply while, in the present case, the membrane of the rubber tube I inserted in the frame E of the station
welding tube is swollen blocking the film G and completely obstructing the passage H on
all its width, the gas which penetrates into the tray M is injected through the circuit of Fluid J practiced in the frame E, this operation being carried out while the whole is completely sealed: In fact the mold L has come press against the bottom of the frame E of the tooling D, the passage of the film H itself being completely
watertight because obstructed, in the present case, by a rubber tube I inflatable with air or any other fluid, but which can be obstructed by any other system and both above and below the film as shown in FIG. N "2 .

Ensuite toujours en gardant cette étanchéité parfaite, le piston B du verin A vient presser la plaque de chauffe F sur les joints K du moule L soudant ainsi le film G sur la barquette M pour l'operculer.  Then still keeping this perfect seal, the piston B of the cylinder A presses the heating plate F on the joints K of the mold L thus welding the film G on the tray M to seal it.

Ensuite, le moule L en s'abaissant libére la barquette M operculée. La membrane du tube pneumatique I se dégongfle alors laissant à nouveau glisser le film G sur la nouvelle barquette suivante à operculer.  Then, the mold L, by lowering, releases the sealed tray M. The membrane of the pneumatic tube I then deflates, again allowing the film G to slide over the next new tray to be sealed.

Le remplissage de barquette en produits liquides, pateux ou visqueux de plus ou moins forte densité peut s'effectuer par l'intermédiaire de buses J rétractables ou pas placées dans le cadre E, après que cette dernière soit mise sous
atmosphère controlée, procurant ainsi au produit une parfaite protection contre
toutes pollutions, ce dernier n'ayant plus aucun contact avec 1' atmosphère extéreure.The filling of trays with liquid, pasty or viscous products of greater or lesser density can be carried out by means of nozzles J retractable or not placed in frame E, after the latter is placed under
controlled atmosphere, thus providing the product with perfect protection against
all pollution, the latter no longer having any contact with one external atmosphere.

Selon une autre caractéristique et avantage de cette invention, l'on
obtient au moins 10 /0, voire 20 et plus de perte de film G en moins, par le fait
que la réinjection de gaz sur ces machines de conditionnement plus
particulièrement des thermoformeuses, ne s'effectue plus par les trous pratiqués
sur les cotés, le long des chaines d'entrainement, sur une bande de film perdue
pour cet usage, mais directement par des injecteurs J placés dans le cadre ou toute
autre partie du poste de soudure rendu totalement étanche.According to another characteristic and advantage of this invention, one
obtains at least 10/0, or even 20 and more loss of film G less, by the fact
that gas re-injection on these packaging machines more
particularly thermoformers, no longer takes place through the holes made
on the sides, along the drive chains, on a lost strip of film
for this purpose, but directly by J injectors placed in the frame or any
other part of the welding station made completely waterproof.

Selon une autre caractéristique et avantage de cette invention,
ce procédé supprime et remplace avantageusement, sur une thermoformeuse ou
operculeuse le système de blocage de film nécessaire pour l'impression du film. According to another characteristic and advantage of this invention,
this process advantageously eliminates and replaces, on a thermoforming machine or
the film blocking system necessary for printing the film.
