Abstract

The isolating frame consists of a surround (17), a transparent sheet (3) and one or more strips (4, 5, 6) forming a zone (12) in which a depression is created through a suction hole (10) once the serigraphy screen has been set in place. One of the strips (4) is fixed and at least one other (5, 6) is movable to allow the low-pressure zone to be varied in dimensions according to requirements. The fixed strip is held below the level of the suction hole by a wire (9), and the moving strips are able to move in different directions, preferably perpendicular to one another, having their movable ends fastened by magnetic stops (8).

Description

La présente invention concerne un châssis destiné à recevoir un écran de sérigraphie pour l'exposer à un rayonnement ultra-violet.The present invention relates to a chassis intended to receive a screen printing screen to expose it to ultraviolet radiation.

Le procédé d'impression par la sérigraphie utilise nécessairement des écrans constitués par des cadres munis d'un tissu tendu. Ce tissu est ensuite enduit d'une solution photo-sensible. Un film du motif à reproduire est alors appliqué contre la solution photo-sensible séchée, et l'ensemble est exposé à un rayonnement ultra-violet. Pour obtenir un résultat satisfaisant, le film doit être bien plaqué contre le tissu de l'écran.The screen printing process necessarily uses screens made up of frames with stretched fabric. This fabric is then coated with a photo-sensitive solution. A film of the motif reproduce is then applied against the solution photo-sensitive dried, and the whole is exposed to a ultraviolet radiation. To get a result satisfactory, the film must be properly pressed against the screen fabric.

La technique actuelle, de loin la plus répandue, consiste à utiliser un châssis d'insolation constitué de deux armatures rectangulaires tubulaires plus grandes que le cadre maximum à insoler. L'un supporte une glace transparente, l'autre supporte un tapis étanche en caoutchouc souple. Un joint à lèvre assure l'étanchéité entre les deux armatures rectangulaires tubulaires. L'écran à insoler est placé entre la glace et le tapis. Une dépression est entretenue entre ces deux éléments par une pompe à vide. Le film est ainsi serré entre la glace et l'écran.The current technique, by far the most widespread, is to use an exposure frame made up of two rectangular tubular frames larger than the maximum frame to be exposed. Mon supports transparent glass, the other supports one waterproof soft rubber mat. A lip seal seals between the two frames rectangular tubular. The screen to be exposed is placed between the ice and the carpet. Depression is maintained between these two elements by a vacuum pump. The movie is thus clamped between the glass and the screen.

Après une exposition de quelques minutes dans un rayonnement UV, la pression est rétablie, l'écran peut être enlevé du châssis d'insolation, une révélation à l'eau permet de l'utiliser pour l'impression. L'ensemble de l'opération est appelée un report.After an exposure of a few minutes in UV radiation, the pressure is restored, the screen can be removed from the sunshine frame, a revelation to water allows it to be used for printing. All of the operation is called a postponement.

Ce type de châssis très utilisé actuellement a l'inconvénient d'être assez complexe, par conséquent d'être cher. Sa mise en oeuvre n'est pas très rapide.This type of chassis which is widely used today has the disadvantage of being quite complex, therefore to be expensive. Its implementation is not very fast.

Une autre technique dite « à la ficelle » peut être employée pour insoler des écrans de grand format. Elle est mise en oeuvre de la façon suivante : le film de l'image à reproduire est placé sur l'écran. On entoure le film avec une cordelette de lin ou autre matière molle. A la jonction des deux bouts de la cordelette on fait passer un tube pour aspirer dans la surface contenant le film. L'ensemble est recouvert largement en dehors de la cordelette par une feuille mince et transparente. L'aspiration est mise en oeuvre et le film est serré entre le tissu et la feuille transparente, et l'insolation peut commencer. La feuille mince transparente, généralement du polyester 100 microns en rouleau, prend la poussière, est très difficile à manipuler et doit être jetée à chaque opération. Un autre inconvénient, de ce procédé : il est très long à mettre en oeuvre et ne peut convenir que pour des insolations peu fréquentes.Another technique called "by the string" can be used to insulate large screens. It is implemented in the following way: the film of the image to be reproduced is placed on the screen. We surround the film with a cord of linen or other soft material. AT the junction of the two ends of the cord we make pass a tube to suck in the surface containing the movie. The whole is covered largely outside the cord by a thin and transparent sheet. The suction is implemented and the film is clamped between the fabric and the transparent sheet, and the insolation can to start. The thin transparent sheet, usually polyester 100 microns in roll, takes dust, is very difficult to handle and must be discarded each time surgery. Another drawback of this process: it is very long to implement and can only be suitable for infrequent sunstrokes.

La présente invention permet de remédier à ces inconvénients en proposant un châssis très simplifié d'un prix de revient très inférieur (de l'ordre de 3 fois moins cher) à celui d'un châssis classique. Sa mise en oeuvre est beaucoup plus rapide que celle d'un châssis classique et à plus forte raison que celle de la méthode « à la ficelle ».The present invention makes it possible to remedy these disadvantages by offering a very simplified chassis of a much lower cost price (around 3 times cheaper) than a conventional chassis. Its implementation work is much faster than that of a chassis classic and a fortiori that of the method "By the string".

L'invention concerne ainsi un châssis tel que défini dans la revendication 1, et dont des variantes sont spécifiées dans les revendications dépendantes.The invention thus relates to a chassis such as defined in claim 1, and variants thereof are specified in the dependent claims.

La présente invention consiste ainsi en un châssis d'insolation dans lequel subsiste seulement une armature, notamment rectangulaire en tôle pliée, porteuse d'une glace. La dépression est effectuée entre la glace et le tissu rendu étanche par la solution photo sensible. Un profil ou bourrelet de matière souple disposé sur la glace permet de délimiter la zone de dépression.The present invention thus consists of a exposure frame in which only one remains frame, in particular rectangular in folded sheet metal, load-bearing an ice cream. The depression is carried out between the ice and the fabric made waterproof by the photo-sensitive solution. A profile or bead of flexible material placed on the ice allows to delimit the depression area.

A cet effet le châssis d'insolation peut comporter une armature rectangulaire légèrement inclinée en arrière et reposant sur un socle. Sur cette armature est fixée une glace, dont le format, plus petit que l'écran à insoler, doit être de quelques centimètres plus grand que le motif maximum à insoler. Il peut comporter en outre :

  • un tube en élastomère en position horizontale fixe, situé plus bas que la glace, qui détermine la position basse de la zone de dépression et/ou
  • un tube en élastomère en position verticale fixe, situé le long à l'intérieur du bord de la glace, qui détermine la position extérieure droite ou gauche de la zone de dépression.
  • Au moins un tube élastomère, peut avoir chacune de ses extrémités attaché à un curseur ou un plot, et en particulier :
    • un tube en position horizontale, mobile sur la surface de la glace, détermine en fonction du format à insoler la position haute de la dépression et/ou
    • un tube en position verticale, mobile sur la surface de la glace, détermine en fonction du format à insoler l'autre position gauche ou droite de la zone de dépression.
To this end, the exposure frame may include a rectangular frame slightly inclined at the rear and resting on a base. On this frame is fixed a glass, the format of which, smaller than the screen to be exposed, must be a few centimeters larger than the maximum pattern to be exposed. It can also include:
  • an elastomer tube in a fixed horizontal position, located lower than the glass, which determines the low position of the vacuum zone and / or
  • an elastomeric tube in a fixed vertical position, located along the inside of the edge of the glass, which determines the right or left external position of the vacuum zone.
  • At least one elastomeric tube, can have each of its ends attached to a slider or a stud, and in particular:
    • a tube in a horizontal position, movable on the surface of the glass, determines according to the format to be exposed the high position of the depression and / or
    • a tube in vertical position, movable on the surface of the glass, determines according to the format to be exposed the other left or right position of the vacuum zone.

Une ouverture, située par exemple à l'intérieur de l'angle des deux tubes en position fixe, permet de faire communiquer l'intérieur du rectangle déterminé par les quatre tubes, avec une pompe à vide.An opening, located for example at inside the angle of the two tubes in a fixed position, allows to communicate inside the rectangle determined by the four tubes, with a vacuum pump.

Le fonctionnement est le suivant : le ou les deux tubes mobiles sont réglés en fonction du format à insoler. L'écran est placé en position devant la glace, en appui sur une traverse horizontale située en avant et sous le niveau de la glace. L'opérateur exerce une pression pour aplatir légèrement les tubes, et met en route la pompe à vide. La dépression commence, elle aplatit davantage les quatre tubes y compris à l'endroit des croisements. Les fuites dues aux croisements diminuent, la dépression augmente et plaque ensemble la glace, le film, et le tissu préalablement enduit.The operation is as follows: the two movable tubes are adjusted according to the format to insolate. The screen is placed in position in front of the glass, resting on a horizontal crossbar located in front and below ice level. The operator exercises pressure to slightly flatten the tubes, and brings run the vacuum pump. Depression begins, it further flattens all four tubes including crosses. Leaks due to crossings decrease, depression increases and together glass, film, and previously coated fabric.

L'insolation peut commencer. Sunstroke can begin.

Le châssis objet de l'invention sera mieux décrit en s'appuyant sur les dessins annexés dans lesquels :

  • la figure 1 représente une vue de côté du châssis.
  • La figure 2 représente une vue de face du châssis.
  • Les figures 3, 4, 5a, et 5b, représentent des variantes de l'invention.
The chassis which is the subject of the invention will be better described on the basis of the appended drawings in which:
  • Figure 1 shows a side view of the chassis.
  • Figure 2 shows a front view of the chassis.
  • Figures 3, 4, 5a, and 5b show variants of the invention.

Tel qu'il est représenté sur les figures 1 et 2, le châssis se compose d'un socle 2 réglable en assise par quatre pieds 13 et de deux montants 1 et la, reliés entre eux par des traverses horizontales 14 et 15, formant une armature rectangulaire 17 légèrement inclinée en arrière sur laquelle prend appui une glace 3.As shown in Figures 1 and 2, the chassis consists of a base 2 adjustable in seat by four legs 13 and two uprights 1 and la, connected between them by horizontal crosspieces 14 and 15, forming a slightly inclined rectangular frame 17 behind which is supported by a window 3.

A cet effet la glace 3 a des dimensions supérieures de l'ordre de 1 à 2 cm à celles de l'intérieur de l'armature 17. La glace 3 est retenue par un relief 16 de la traverse 14, d'une épaisseur égale à celle de la glace 3. Le relief 16 d'une largeur de l'ordre de quelques centimètres disposé sans interruption tout le long de la traverse 14 a pour fonction d'empêcher la glace 3 de glisser vers le bas.For this purpose the glass 3 has dimensions 1 to 2 cm higher than those of inside the frame 17. The glass 3 is retained by a relief 16 of the crosspiece 14, of a thickness equal to that of ice 3. The relief 16 with a width of the order of a few centimeters arranged without interruption all along the crossbar 14 has the function of preventing ice 3 to slide down.

Ce relief 16 comporte au moins un trou 10 recevant un tuyau d'aspiration par lequel la dépression sera communiquée à la zone de dépression 12. Le trou 10 est situé dans l'angle intérieur fixe du bourrelet 4. Une traverse 18 horizontale située plus bas et en avant du bord inférieur de la glace 3 sert à poser l'écran qui prend ensuite appui sur les bourrelets et qui se plaque sur la glace 3 inclinée en arrière, sous l'effet de la dépression.This relief 16 includes at least one hole 10 receiving a suction pipe through which the vacuum will be communicated to the depression zone 12. Hole 10 is located in the fixed interior corner of the bead 4. A horizontal cross member 18 located lower and in front of the lower edge of the glass 3 is used to place the screen which then takes support on the beads and which is pressed on the glass 3 tilted back, under the effect of the depression.

Un ensemble de bourrelets 4, 5, 6 détermine la surface 12. Les dimensions de la surface (ou zone de dépression) 12 sont réglables par le déplacement des bourrelets 5 et 6. A set of beads 4, 5, 6 determines the surface 12. The dimensions of the surface (or area of depression) 12 are adjustable by moving the beads 5 and 6.

Le bourrelet 5, horizontal, est tenu à ses extrémités par des plots magnétiques 8 pouvant être déplacés le long des montants 1 et 1a. La surface des plots magnétiques 8 en contact avec les montants est revêtue d'une matière glissante, par exemple une feuille de polyéthylène adhésivée qui évite de rayer les montants 1 et 1a et la traverse supérieure 15. Le bourrelet 6, vertical, est tenu en haut par un plot magnétique 8 et en bas par un cylindre 11 percé d'un trou, glissant dans un rail formé par la réunion des pièces 14 et 18, par l'intermédiaire de câles d'épaisseur 19 situées à chaque extrémité des pièces 14 et 18.The bead 5, horizontal, is held at its ends by magnetic pads 8 which can be moved along uprights 1 and 1a. The surface of magnetic studs 8 in contact with the uprights coated with a sliding material, for example a sheet polyethylene adhesive which prevents scratching the uprights 1 and 1a and the upper cross member 15. The bead 6, vertical, is held at the top by a magnetic stud 8 and bottom by a cylinder 11 pierced with a hole, sliding in a rail formed by the union of parts 14 and 18, by through 19 thickness shims located at each end of parts 14 and 18.

Les bourrelets 4, 5, et 6 sont faits d'une matière souple de forme tubulaire, (par exemple un tube d'élastomère de faible dureté Shore, par exemple entre 30 et 50, et de faible épaisseur.The beads 4, 5, and 6 are made of flexible material of tubular shape (for example a tube elastomer of low Shore hardness, for example between 30 and 50, and of small thickness.

Cette forme souple et creuse permet de réduire les fuites d'air au croisement des bourrelets 4, 5 et 6.This flexible and hollow shape helps reduce air leaks at the crossing of the beads 4, 5 and 6.

Le bourrelet 4 est représenté (d'une manière péférentielle) en une seule partie sur la figure 2, l'angle étant retenu par un tirant 9. Cette disposition évite un croisement. Il pourrait aussi tout aussi bien être réalisé en deux parties à la manière des bourrelets 5 et 6.The bead 4 is shown (in a way preferential) in a single part in FIG. 2, the angle being retained by a tie rod 9. This arrangement avoids crossing. He could also just as well be made in two parts in the manner of beads 5 and 6.

Les plots 7 retenant le bourrelet 4 sont fixes, par exemple de simples vis.The studs 7 retaining the bead 4 are fixed, for example simple screws.

Le châssis selon l'invention est particulièrement destiné à l'insolation d'écrans de sérigraphie.The chassis according to the invention is particularly intended for the insolation of screens of screen printing.

Les plots magnétiques 8 peuvent être remplacés par des cylindres 11 percés d'un trou et glissant dans trois rails situés respectivement sur la traverse supérieure 15 et les montants verticaux 1 et 1a, et dont un référencé 20 est représenté aux figures 3 et 4.Magnetic pads 8 can be replaced by cylinders 11 pierced with a hole and sliding in three rails respectively located on the sleeper upper 15 and the vertical uprights 1 and 1a, and of which referenced 20 is shown in FIGS. 3 and 4.

On diminuera sensiblement les fuites aux croisements des bourrelets 4, 5 et 6 en remplaçant le bourrelet 4 par un profil 21 de faible dureté Shore, par exemple 35, collé par un adhésif 23 au même endroit et dont la section est représentée aux figures 5a et 5b. Le profil 21 présente une lèvre 22. Au moins un des bourrelets mobile 5, 6 pourrait être remplacé par un tel profil 21 pourvu d'une lèvre 22, mais non collé. Ce profil 21 présente avantageusement une section allongée s'amincissant vers l'intérieur de la surface 12 jusqu'à une région de pointe 26 pour faciliter le placage de l'écran de sérigraphie.We will significantly reduce leaks to crosses of the beads 4, 5 and 6 by replacing the bead 4 by a profile 21 of low Shore hardness, by example 35, glued with adhesive 23 in the same place and whose section is shown in Figures 5a and 5b. The profile 21 has a lip 22. At least one of movable beads 5, 6 could be replaced by such a profile 21 provided with a lip 22, but not glued. This profile 21 advantageously has an elongated section tapering inward from surface 12 to a tip region 26 to facilitate the plating of the screen printing screen.

A la figure 5a, on a représenté un bourrelet fixe 5' qui occupe deux côtés de la surface 12 dont le contour est complémenté par le profil collé 21, ce qui correspond à des cadres de même dimension.In Figure 5a, there is shown a bead fixed 5 'which occupies two sides of the surface 12, the contour is complemented by the glued profile 21, which corresponds to frames of the same dimension.

Bien entendu, ce mode de réalisation peut mettre en oeuvre un ou deux bourrelets mobiles (5, 6).Of course, this embodiment can use one or two movable beads (5, 6).
