Description

BLOUSE THERMOCOLLÉE ET DECOUPÉE SOUS PRESSION D’UN OUTIL CHAUFFANT, PROCÉDÉ ET DISPOSITIF POUR LA FABRIQUERBLOUSE HEAT-SEALED AND CUT UNDER PRESSURE WITH A HEATED TOOL, METHOD AND DEVICE FOR MANUFACTURING IT

Domaine technique de l’inventionTechnical field of the invention

La présente invention vise une blouse thermocollée et découpée sous pression d’un outil chauffant, un procédé et un dispositif pour la fabriquer. Elle s’applique, en particulier blouses pour visiteurs d’établissements hospitaliers et pour le personnel soignant quand il passe d’une chambre de soin à une autre.The present invention relates to a heat-sealed and pressure-cut gown of a heating tool, a method and a device for manufacturing it. It applies, in particular, to gowns for visitors to hospital establishments and for nursing staff when moving from one treatment room to another.

État de la techniqueState of the art

Les blouses pour visiteurs d’établissements hospitaliers sont actuellement réalisées par soudure par ultrasons, ce qui requiert une part de main d'œuvre significative qui empêche, d’une part de les fabriquer à proximité de leur lieu d’utilisation et, d’autre part, de les fabriquer à moindre coût. Or, en période de pandémie, il est nécessaire de disposer de ce type de bouses par millions d’unités.Gowns for visitors to hospital establishments are currently produced by ultrasonic welding, which requires a significant amount of labor which prevents them, on the one hand, from being manufactured close to their place of use and, on the other hand, to manufacture them at a lower cost. However, during a pandemic, it is necessary to have this type of dung in millions of units.

Présentation de l’inventionPresentation of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these drawbacks.

À cet effet, la présente invention vise, selon un premier aspect, une blouse comportant :
- une face dite avant,
- une face dite arrière,
au moins une des faces comportant un matériau fusible à moins de 300°C, les faces avant et arrière étant reliées entre elles sur une partie de leurs bords par thermocollage et découpe sous pression d’un outil chauffant, d’autres parties de leurs bords n’étant pas reliées entre elles pour former le passage de la tête et des membres de l’utilisateur.To this end, the present invention relates, according to a first aspect, to a gown comprising:
- a so-called front face,
- a so-called rear face,
at least one of the faces comprising a material that melts at less than 300°C, the front and rear faces being joined together on part of their edges by heat-sealing and cutting under pressure of a heating tool, other parts of their edges not being interconnected to form the passage of the user's head and limbs.

Grâce à ces dispositions, la blouse objet de l’invention est de fabrication facile et peu onéreuse.By virtue of these arrangements, the gown which is the subject of the invention is easy and inexpensive to manufacture.

Dans des modes de réalisation, la blouse comporte une ceinture thermocollée sous pression d’un outil chauffant sur un bord d’au moins une des faces de la blouse.In some embodiments, the blouse comprises a belt heat-sealed under pressure from a heating tool on an edge of at least one of the faces of the blouse.

Grâce à ces dispositions, la blouse peut être resserrée par l’utilisateur autour de son abdomen.Thanks to these provisions, the blouse can be tightened by the user around his abdomen.

Dans des modes de réalisation, les deux faces sont constituées du même matériau uniforme.In embodiments, both faces are made of the same uniform material.

Grâce à ces dispositions, la fusion des bords superposés des deux faces assure une soudure plus résistante.Thanks to these provisions, the fusion of the superimposed edges of the two faces ensures a more resistant weld.

Dans des modes de réalisation, le blouse comporte un pli reliant les faces avant et arrière, ce pli étant positionné à l’extrémité des faces de la blouse correspondant aux épaules de l’utilisateur.In some embodiments, the blouse comprises a pleat connecting the front and rear faces, this pleat being positioned at the end of the faces of the blouse corresponding to the shoulders of the user.

Grâce à ces dispositions, la fabrication de blouses en série ne requiert qu’un rouleau de matériau que l’on découpe et repli pour former les deux faces.Thanks to these provisions, the mass production of gowns only requires a roll of material that is cut and folded to form the two sides.

Selon un deuxième aspect, la présente invention vise un procédé de fabrication d’une blouse qui comporte :
- une étape de positionnement en superposition de deux surfaces, au moins une des surfaces comportant un matériau fusible à moins de 300°C, et
- une étape de thermocollage et de découpage, sous pression d’un outil chauffant, de bords superposés des deux surfaces à une température au moins égale à la température de fusion du matériau d’au moins une des surfaces.According to a second aspect, the present invention relates to a process for manufacturing a gown which comprises:
- a superimposed positioning step of two surfaces, at least one of the surfaces comprising a material that melts at less than 300°C, and
- a step of thermal bonding and cutting, under pressure of a heating tool, of superimposed edges of the two surfaces at a temperature at least equal to the melting temperature of the material of at least one of the surfaces.

Dans des modes de réalisation, le procédé comporte, de plus, avant l’étape de thermocollage et de découpage, une étape de positionnement d’une ceinture à cheval sur un bord d’au moins une des surfaces, l’étape de thermocollage et de découpage se faisant sur une partie de la ceinture.In some embodiments, the method further comprises, before the heat-sealing and cutting step, a step of positioning a belt astride an edge of at least one of the surfaces, the heat-sealing step and cutting being done on part of the belt.

Dans des modes de réalisation, le procédé comporte une étape de pliage d’un matériau en rouleau qui superpose les deux surfaces.In embodiments, the method includes a step of folding a roll material that overlaps the two surfaces.

Selon un troisième aspect, la présente invention vise un dispositif de fabrication d’une blouse qui comporte :
- une surface de support en position et en superposition de deux surfaces d’un matériau fusible, et
- un moyen de thermocollage et de découpage, sous pression d’un outil chauffant, de bords superposés des deux surfaces à une température au moins égale à la température de fusion du matériau d’au moins une des surfaces.According to a third aspect, the present invention relates to a device for manufacturing a gown which comprises:
- a support surface in position and in superposition of two surfaces of a fusible material, and
- Means for heat sealing and cutting, under pressure from a heating tool, superimposed edges of the two surfaces at a temperature at least equal to the melting temperature of the material of at least one of the surfaces.

Dans des modes de réalisation, le dispositif comporte un gabarit fixe pour accueillir au moins une partie amovible de la surface de support.In embodiments, the device comprises a fixed template to accommodate at least a removable part of the support surface.

Dans des modes de réalisation, le dispositif comporte un moyen de pliage d’un matériau en rouleau configuré pour superposer les deux surfaces reliées par un pli.In embodiments, the device comprises means for folding a roll material configured to overlap the two surfaces connected by a fold.

Les avantages, buts et caractéristiques de ce procédé et de ce dispositif étant similaires à ceux de la blouse objet de l’invention, ils ne sont pas rappelés ici.The advantages, aims and characteristics of this method and of this device being similar to those of the gown which is the subject of the invention, they are not repeated here.

La présente description est donnée à titre non limitatif, chaque caractéristique d’un mode de réalisation pouvant être combinée à toute autre caractéristique de tout autre mode de réalisation de manière avantageuse.This description is given on a non-limiting basis, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

On note, dès à présent, que les figures ne sont pas à l’échelle.Note that the figures are not to scale.

Dans toute la description, on appelle « supérieur » ou « haut » ce qui est en haut ou orienté vers le haut, sur les figures 1, 2, 5 à 8, figures qui correspondent à la configuration d’utilisation normale de la blouse (figures 1 et 2) et du dispositif de fabrication (figures 5 à 8) objets de l’invention. On appelle « inférieur » ou « bas », ce qui est en bas ou orienté vers le bas, dans ces figures. Les notions de verticale et horizontale découlent de ces définitions. On appelle « interne » ce qui proche de ou orienté vers un axe longitudinal vertical 30 de la blouse ou un axe vertical central 56 du dispositif de fabrication et, externe, ce qui est orienté à l’opposé de cet axe 30 ou 56. La hauteur de la blouse est définie selon l’axe 30. La hauteur du dispositif est définie selon l’axe 56.Throughout the description, "upper" or "top" is what is at the top or oriented upwards, in figures 1, 2, 5 to 8, figures which correspond to the normal configuration of use of the gown ( Figures 1 and 2) and the manufacturing device (Figures 5 to 8) objects of the invention. We call "lower" or "low", what is below or directed downwards, in these figures. The notions of vertical and horizontal derive from these definitions. “Internal” is what is close to or oriented towards a vertical longitudinal axis 30 of the gown or a central vertical axis 56 of the manufacturing device, and external is what is oriented opposite this axis 30 or 56. gown height is defined along axis 30. Device height is defined along axis 56.

On observe, en , une blouse 20 présentant une face avant 31 intégralement superposée à une face arrière 32. Dans d’autres modes de réalisation (non représentés) les faces avant et arrière ne se superposent pas intégralement.We observe, in , a gown 20 having a front face 31 fully superimposed on a rear face 32. In other embodiments (not shown) the front and rear faces do not overlap completely.

Chaque face comporte un col 33, un devant 39 et des manches 34 entourées par des bords 35 au niveau des épaules, 36 formant des ouvertures pour le passage des mains et des poignets et 37 du côté du devant 39. Le devant 39 est entouré d’un bord 38 au niveau du thorax et de l’abdomen et d’un bord 40 formant ouverture de passage des jambes.Each side has a collar 33, a front 39 and sleeves 34 surrounded by edges 35 at the shoulders, 36 forming openings for the passage of the hands and wrists and 37 on the side of the front 39. The front 39 is surrounded by an edge 38 at the level of the thorax and the abdomen and an edge 40 forming an opening for the passage of the legs.

Une ceinture optionnelle 48 complète cette blouse 20.An optional 48 belt completes this 20 blouse.

Les faces avant 31 et arrière 32 sont reliées entre elles sur une partie de leurs bords par thermocollage et découpage sous pression d’un outil chauffant. Préférentiellement, ces bords thermocollés et découpés sous pression d’un outil chauffant comportent le bord 38 et le bord 37. D’autres parties des bords des faces avant 31 et arrière 32 ne sont pas reliées entre elles pour former le passage de la tête et des membres de l’utilisateur. Il s’agit du col 33 et des bords 36 et 40. Le bord supérieur 35 peut être thermocollé ou formé par un pli d’une bande, par exemple déroulée depuis un rouleau, d’un matériau uniforme. Dans ce dernier cas, la blouse 20 comporte un pli 35 reliant les faces avant 31 et arrière 32, ce pli étant positionné à l’extrémité des faces de la blouse 20 correspondant aux épaules de l’utilisateur. La fabrication de blouses 20 en série ne requiert alors qu’un rouleau de matériau que l’on découpe et repli pour former les deux faces 31 et 32.The front 31 and rear 32 faces are joined together on part of their edges by thermal bonding and cutting under pressure from a heating tool. Preferably, these heat-bonded and pressure-cut edges of a heating tool comprise the edge 38 and the edge 37. Other parts of the edges of the front 31 and rear 32 faces are not interconnected to form the passage for the head and user members. These are the neck 33 and the edges 36 and 40. The upper edge 35 can be heat sealed or formed by a fold of a strip, for example unrolled from a roll, of a uniform material. In the latter case, the blouse 20 comprises a fold 35 connecting the front 31 and rear 32 faces, this fold being positioned at the end of the faces of the blouse 20 corresponding to the shoulders of the user. The manufacture of blouses 20 in series then requires only a roll of material which is cut and folded to form the two faces 31 and 32.

Grâce à l’utilisation du thermocollage et du découpage sous pression d’un outil chauffant et de découpes et, éventuellement de pliage, uniquement, la blouse 20 est de fabrication facile et peu onéreuse.Thanks to the use of heat sealing and cutting under pressure of a heating tool and cutouts and, possibly, folding, only, the gown 20 is easy and inexpensive to manufacture.

On observe que la ceinture optionnelle 48 atteint un bord 38. Elle est ainsi solidarisée à la blouse 20 par thermocollage sous pression d’un outil chauffant, et préférentiellement aussi découpage par cet outil. Ainsi, la blouse 20 comporte une ceinture 48 thermocollée sur un bord 38 d’au moins une des faces de la blouse 20, ici l’avant 39.It is observed that the optional belt 48 reaches an edge 38. It is thus secured to the gown 20 by heat sealing under pressure from a heating tool, and preferably also cutting by this tool. Thus, the blouse 20 comprises a belt 48 heat-sealed on an edge 38 of at least one of the faces of the blouse 20, here the front 39.

La blouse peut ainsi être resserrée par l’utilisateur autour de son abdomen.The gown can thus be tightened by the user around his abdomen.

Préférentiellement, les deux faces sont constituées du même matériau uniforme. Ainsi, lors du thermocollage et du découpage sous pression d’un outil chauffant, la fusion des bords superposés des deux faces 31 et 32 assure une soudure plus résistante. Les dimensions de la blouse sont, par exemple, les suivantes :
- dimension d’un bord 36 à l’autre : 170 cm ;
- hauteur des manches : 15 à 20 cm ;
- largeur de col : 15 à 25 cm ;
- largeur minimale au niveau du thorax : 60 à 70 cm ;
- dimension de partie oblique sous les épaules : 16 à 20 cm ; et
- hauteur maximale : 100 à 120 cm.Preferably, the two faces are made of the same uniform material. Thus, during heat sealing and cutting under pressure of a heating tool, the fusion of the superimposed edges of the two faces 31 and 32 ensures a stronger weld. The dimensions of the gown are, for example, the following:
- dimension from one edge 36 to the other: 170 cm;
- sleeve height: 15 to 20 cm;
- collar width: 15 to 25 cm;
- minimum width at chest level: 60 to 70 cm;
- dimension of oblique part under the shoulders: 16 to 20 cm; And
- maximum height: 100 to 120 cm.

On observe, en , une feuille 41 de matériau repliée sur elle-même dont la largeur, qui correspond à la dimension horizontale en , est égale à la distance entre les bords 36 de la blouse 20 finie. Le pli 35 est représenté en trait continu. Les lignes de découpe 33, pour le col, et 40 sont représentées en traits discontinus fin. Les lignes de thermocollage et découpage sous pression d’un outil chauffant correspondant aux bords 37 et 38 sont représentées en traits discontinus épais. La ceinture 48 est posée à cheval sur une ligne de thermocollage et découpage sous pression d’un outil chauffant.We observe, in , a sheet 41 of material folded on itself whose width, which corresponds to the horizontal dimension in , is equal to the distance between the edges 36 of the finished gown 20. The ply 35 is shown in continuous lines. The cutting lines 33, for the neck, and 40 are shown in thin dashed lines. The lines of thermal bonding and cutting under pressure of a heating tool corresponding to edges 37 and 38 are shown in thick broken lines. The belt 48 is placed astride a heat-sealing and cutting line under pressure from a heating tool.

On observe, en , la forme des outils 42 de thermocollage et découpage en correspondance avec la feuille 41 et la ceinture 48. Cette forme correspond à celle des bords 37 et 38 et les entoure. Les outils 42 appliquent une pression sur les deux faces de la blouse et une température supérieure à la température de fusion d’au moins un des matériaux constituant l’une des faces. Préférentiellement, la température à laquelle est portée la surface des outils 42 est inférieure à la température de rétractation des matériaux des deux faces de la blouse de telle manière que, de part et d’autre de la zone sous pression.We observe, in , the shape of the tools 42 for heat sealing and cutting in correspondence with the sheet 41 and the belt 48. This shape corresponds to that of the edges 37 and 38 and surrounds them. The tools 42 apply a pressure to the two faces of the gown and a temperature above the melting temperature of at least one of the materials constituting one of the faces. Preferably, the temperature to which the surface of the tools 42 is brought is lower than the temperature of retraction of the materials of the two faces of the gown in such a way that, on either side of the zone under pressure.

On observe, en , des outils de positionnement mécanique de la feuille 41 sous les outils de thermocollage et découpage 42. Les partie 43 et 44 correspondent à des gabarits fixes plans de guidage. La partie plane et rigide 45, munie de poignées 46 et 47 est amovible et porte, initialement, la feuille 41 puis, après thermocollage et découpage sous pression des outils chauffants 42, la blouse 20.We observe, in , tools for mechanical positioning of the sheet 41 under the heat-sealing and cutting tools 42. The parts 43 and 44 correspond to fixed templates guide planes. The flat and rigid part 45, provided with handles 46 and 47 is removable and carries, initially, the sheet 41 then, after heat sealing and cutting under pressure of the heating tools 42, the blouse 20.

Des barres 49, en dessous des gabarits 43 et 44 et de la partie mobile 45 retiennent celles-ci en position une fois la partie mobile 45 positionnée entre les gabarits 43 et 44.Bars 49, below the jigs 43 and 44 and the movable part 45 hold them in position once the movable part 45 is positioned between the jigs 43 and 44.

On observe, en à 7, un dispositif 50 de fabrication de blouses. On retrouve, dans ces figures, le gabarit de guidage 43 (la gabarit 44 étant caché par le gabarit 43) et la partie amovible 45 munie de la poignée 46 (la poigne 47 étant cachée par la poignée 46). En , la partie 45 n’a pas encore été positionnée entre les gabarits de guidage 43 et 44. En , la partie 45 a été positionnée entre les gabarits de guidage 43 et 44.We observe, in at 7, a device 50 for manufacturing gowns. We find, in these figures, the guide template 43 (the template 44 being hidden by the template 43) and the removable part 45 provided with the handle 46 (the handle 47 being hidden by the handle 46). In , the part 45 has not yet been positioned between the guide templates 43 and 44. In , part 45 has been positioned between guide templates 43 and 44.

Le dispositif 50 comporte un bâti fixe 52 muni de pieds 51. Le dispositif 50 comporte aussi une presse 55 mobile portant, sur leur face inférieure, les outils de thermocollage et découpage 42. La presse 55 est guidée dans sa descente par des guides 53. La motorisation électrique et/ou par vérin, de la presse 55 n’est pas représentée dans les figures.The device 50 comprises a fixed frame 52 provided with feet 51. The device 50 also comprises a mobile press 55 carrying, on their underside, the heat-sealing and cutting tools 42. The press 55 is guided in its descent by guides 53. The electric and/or jack motorization of the press 55 is not shown in the figures.

Comme illustré en , un outil de thermocollage et de découpage 42 qui comporte un fil résistif 59, alimenté en très basse tension, tendu sur un lit de silicone 58 (matériau qui résiste à 700°C), lui-même collé sur un isolant thermique et électrique 57, par exemple du bois, un matériau plastique ou du silicone rigide. Le fil résistif 59 est enveloppé et maintenu en place par un film 60, par exemple en Téflon (marque déposée) qui est maintenu sur l'isolant 57. Préférentiellement, une sonde thermique 61 positionnée sur le parcours du fil résistif 59 permet le suivi en température de l’outil et assure le contrôle, avec report sur un panneau de contrôle.As illustrated in , a thermobonding and cutting tool 42 which comprises a resistive wire 59, supplied with very low voltage, stretched over a bed of silicone 58 (material which resists 700° C.), itself bonded to a thermal and electrical insulator 57 , for example wood, a plastic material or rigid silicone. The resistive wire 59 is wrapped and held in place by a film 60, for example made of Teflon (registered trademark) which is held on the insulator 57. Preferably, a thermal probe 61 positioned on the path of the resistive wire 59 allows monitoring in tool temperature and provides control, with report on a control panel.

Dans des modes de réalisation, la blouse et la ceinture sont composées d’un matériau non-tissé, par exemple du polypropylène non tissé, non stérile, à usage unique, d’un grammage de 30 grammes par mètre carré.In embodiments, the gown and the belt are made of a non-woven material, for example non-woven, non-sterile, single-use polypropylene, with a weight of 30 grams per square meter.

A titre d’exemple, il a été réalisé des blouses avec du non-tissé constitué de filaments continus 100% polypropylène (PP) de type SMS (acronyme de « spunbond meltblown spunbond » que l’on peut traduire par « obtenu par filage-nappage/extrusion-soufflage/filage-nappage ») à 100 g/m². Ces tests ont mis en évidence que plus le grammage est élevé plus la soudure est satisfaisante, en termes de solidité et de continuité. Le SMS est un tissu non-tissé constitué de filaments continus 100% polypropylène (PP), disposés au hasard et soudés thermiquement grâce à un procédé de calandrage, ou méthode Spunlaid thermobonded (obtenu par voie fondue/extrusion soufflage), doublé d’une couche de meltblown (consolidation) et d’une autre de spunbonded polypropylène.For example, gowns have been made with nonwovens consisting of 100% polypropylene (PP) continuous filaments of the SMS type (acronym for “spunbond meltblown spunbond” which can be translated as “obtained by spinning- topping/extrusion-blowing/spun-topping”) at 100 g/m². These tests have shown that the higher the weight, the more satisfactory the weld, in terms of solidity and continuity. SMS is a non-woven fabric made up of 100% polypropylene (PP) continuous filaments, randomly arranged and thermally welded using a calendering process, or Spunlaid thermobonded method (obtained by melting/extrusion blow molding), lined with a layer of meltblown (consolidation) and another of spunbonded polypropylene.

Dans le cas où la blouse est en polypropylène SMS, la température cible mesurée sur le fil à chaud est de 160 °C pour que soient réalisés, simultanément, le thermocollage et le découpage. On note que le matériau commence à mollir à partir de 140°C, ce qui permettrait un thermocollage seul, mais que, à la température de 200°C, il y a découpe mais le collage est défectueux. Préférentiellement la température de surface de l’outil 42 est compris entre 150°C et 180°C et, plus préférentiellement, entre 155°C et 170°C.In the case where the gown is made of SMS polypropylene, the target temperature measured on the hot wire is 160°C so that heat sealing and cutting are carried out simultaneously. It is noted that the material begins to soften from 140° C., which would allow thermal bonding alone, but that, at a temperature of 200° C., there is cutting but the bonding is defective. Preferably, the surface temperature of tool 42 is between 150°C and 180°C and, more preferably, between 155°C and 170°C.

Dans des modes de réalisation (non représentés), le dispositif comporte, de plus, un moyen de pliage d’un matériau en rouleau configuré pour superposer les deux surfaces reliées par un pli.In embodiments (not shown), the device further comprises a means for folding a roll material configured to superimpose the two surfaces connected by a fold.

Dans des modes de réalisation (non représentés), le dispositif comporte, de plus :
- un moyen d’approvisionnement automatique en matériau constituant la blouse ;
- un moyen d’éjection automatique de la blouse après thermocollage et découpage ;
- un moyen de pliage automatique de la blouse thermocollée et découpée ;
- un moyen d’ensachage automatique de la blouse pliée et/ou
- une rotative de thermocollage et découpage pour fabriquer jusqu’à une blouse par seconde à partir de deux bandes de matériau superposées.In embodiments (not shown), the device further comprises:
- A means of automatic supply of material constituting the gown;
- A means of automatic ejection of the gown after heat sealing and cutting;
- a means of automatic folding of the heat-sealed and cut-out blouse;
- a means for automatically bagging the folded blouse and/or
- a heat-sealing and cutting machine to manufacture up to one blouse per second from two superimposed strips of material.

On observe, en , des étapes d’un mode de réalisation 70 du procédé de fabrication d’une blouse.We observe, in , of the steps of an embodiment 70 of the method of manufacturing a gown.

Au cours d’une étape 71, on découpe une bande de matériau formant la blouse, par exemple à partir d’un rouleau.During a step 71, a strip of material forming the blouse is cut, for example from a roll.

Au cours d’une étape 72, on replie sur elle-même la bande découpée de manière que ses deux surfaces repliées se superposent parfaitement.During a step 72, the cut strip is folded back on itself so that its two folded surfaces overlap perfectly.

Au cours d’une étape 73, on pose la bande découpée et pliée sur la partie mobile du support de la blouse.During a step 73, the cut and folded strip is placed on the mobile part of the support of the blouse.
