Description

La présente invention concerne un procédé et dispositifs pour la réaZisation d'une machine automatique fabricant des coussins d'air à partir d'une gaine thermoplastique destinés au calage et dans Zes dimensions choisies par Z'utiZisateur.The present invention relates to a method and devices for realizing an automatic machine manufacturing air cushions from a thermoplastic sheath intended for wedging and in the dimensions chosen by the user.

L'invention vise, notamment, Zes machines de ce type, utiZisant de la gaine thermoplastique ou à partir de film thermoplastique.The invention relates, in particular, to machines of this type, using thermoplastic sheath or from thermoplastic film.

Ces machines doivent entre en mesure de réaZiser une soudure continue ne présentant aucune faiblesse ZocaZisée du point de vue de la résistance mécanique, en effet ces types de coussins doivent conserver leur herméticité malgré Zes contraintes de déformations et de pressions auxquelles ils sont soumis.These machines must be able to perform a continuous weld showing no ZocaZized weakness from the point of view of mechanical strength, in fact these types of cushions must keep their airtightness despite the stresses of deformations and pressures to which they are subjected.

IZ est connu dans une technique antérieur une machine à fabriquer des coussins d'air ou Ze gonflage est effectué à Z'aide d' une chambre de dépression, Zes soudures ne sont pas fiables, et la taille des coussins est limitée, dans un autre type de réalistation, une machine ou le gonflage de ces coussins est effectué par une réserve d'air, Zes soudures de cette machine ne sont pas fiables à cause des pZis du à la réserve d7air.Dans une autre réalisation de machine mais à partir de fiZm cette fois ,Za taille des coussins est limitées à deux possibiZités, de plus le prix de cette machine limite sa diffusion. IZ is known in a prior art a machine for manufacturing air cushions or Ze inflation is carried out using a vacuum chamber, Zes welds are not reliable, and the size of the cushions is limited, in another type of realization, a machine or the inflation of these cushions is carried out by an air reserve, Zes welds of this machine are not reliable because of the pZis due to the air reserve. In another realization of machine but from fiZm this time, the size of the cushions is limited to two possibilities, moreover the price of this machine limits its diffusion.

La présente invention vise, justement, à remédier simultanément aux inconvénients de ces types de machines décrites çi-dessus en proposant une machine pour la fabrication de coussins d'air conçue pour que Z'utiZisateur choisisse ce dont iZ a besoin, en Zargeur, en Longueur, et en chapelets, tout en diminuant considérablement le coùt de la construction de la machine.The present invention aims, precisely, to remedy simultaneously the drawbacks of these types of machines described above by proposing a machine for the manufacture of air cushions designed so that the user can choose what iZ needs, in Zarger, in Length, and in strings, while considerably reducing the cost of machine construction.

L'invention vise, également un procédé permettant le gonflage à partir d'une gaine fermée aux deux extrémités, en utilisant la turbulence du fluide (air).The invention also relates to a method allowing inflation from a sheath closed at both ends, using the turbulence of the fluid (air).

L'invention vise, encore un dispositif permettant la coupe sur une partie de la gaine et la prédécoupe , Z' opération se faisant en même temps, et, permet le remplissage d'air de la gaine.The invention also relates to a device allowing the cutting on a part of the sheath and the precut, Z 'operation being done at the same time, and, allows the air filling of the sheath.

Pour atteindre Zes objectifs précités, la machine seZon Z'invention comprend : -Une arrivée d'air décalée par rapport à la fente permettant
Z'introduction de Z'air mais située dans l'axe centraZe.To achieve these objectives, the seZon Z'invention machine includes: -An air intake offset from the slot allowing
Z'introduction of Z'air but located in the central axis.

-Une Zame de scie dont Zes dents sur sa partie centrale (environ 6cm.) sont plus hautes que Ze restant des dents de la lame de scie.-A saw Zame whose Zes teeth on its central part (about 6cm.) Are higher than Ze remaining teeth of the saw blade.

-Une tête de soudure comportant deux dents sur Ze même pian(ces deux dents peuvent égaZement ne pas autre sur Ze méme plan ) permettant la soudure de part et d'autre de la fente effectuée dans la gaine par la lame de scie.-A welding head comprising two teeth on the same plane (these two teeth can also not be different on the same plane) allowing the welding on either side of the slot made in the sheath by the saw blade.

-Un bloc de contre-soudure homogène comportant un plancher supportant deux caoutchouc fixés parallèlement entre eux, une fenêtre permettant Ze passage de la Zame de scie, une barre de contre lame de scie supportant un caoutchouc, et deux dévètisseurs.-A homogeneous counter-weld block comprising a floor supporting two rubbers fixed parallel to each other, a window allowing the passage of the saw blade, a bar against the saw blade supporting a rubber, and two strippers.

Diverses autres caractéristiques ressortent de la description faite çidessous en références aux dessins annexés montrent à titre d'exemples non limitatifs,des formes de réaZisation de Z' objet de Z'invention.Various other characteristics will emerge from the description given below with reference to the appended drawings show, by way of nonlimiting examples, forms of realization of the object of the invention.

La FIG.1 illustre l'ensemble du procédé permettant Ze gonflage, le prédécoupage, et le soudage de la gaine thermoplastique.L'ensemble des dispositifs décrits çi-dessus permet de gonfler une gaine en rouleau soudés aux deux extremités.La lame de scie permet de pratiquer une fente au milieu de la gaine sur ses deux surfaces et de prédécouper Ze restant (en largeur ) ce faisant Z' arrivée d'air étant décalée, la pression et Ze dépit de la turbine autorise Ze gonflage de la gaine par turbulence du fluide qui glisse sous la surface de la gaine en décollant Zes deux surfaces de la gaine à la hauteur de la fente permettant ainsi Z' entrée de l'air dans la gaine.FIG. 1 illustrates the whole process allowing the inflation, the precut, and the welding of the thermoplastic sheath. The set of devices described above makes it possible to inflate a sheath in a roll welded at both ends. makes it possible to make a slit in the middle of the sheath on its two surfaces and to precut Ze remaining (in width) by doing Z 'air intake being offset, the pressure and Ze despite the turbine allows Ze swelling of the sheath by turbulence fluid which slides under the surface of the sheath by peeling off the two surfaces of the sheath at the height of the slit thus allowing the entry of air into the sheath.

Dans une autre réalisation de la machine, on peut obturer la fente sur la surface supérieure de la gaine à Z'aide d'étiquettes auto-collantes distribué par une étiqueteuse automatique, ce qui augmente la rapidité du gonflage.In another embodiment of the machine, the slot can be closed off on the upper surface of the sheath using self-adhesive labels distributed by an automatic labeling machine, which increases the speed of inflation.
