Definitions
- the present invention relates to an introductory gauge for a device for supplying folding box blanks, comprising a vertical gauge body, rounded at its bottom, against which the folding box blanks are pressed to be introduced into the working machine.
- the devices for introducing folding box blanks known to date, commonly called feeders by practitioners, generally include a lower transport member constituted by a series of endless belts placed side by side across the width of the device. These endless belts are driven by a drive roller placed at the front of the device and then pass around a driven roller placed at the rear of the aforementioned device. The upper strand of the endless belts is further supported by a series of rollers so as to constitute a transport plane having a relatively rigid surface.
- a vertical gauge is placed substantially in the axis of the driving roller and above it.
- the cutouts of folding boxes to be introduced are arranged in an inclined manner above the endless belts, their front edge coming to rest against an inclined surface of the gauge while their rear part rests on supports.
- two gauges are mounted side by side across the width of the feeder.
- a clearance corresponding substantially to the thickness of the cut to be introduced is left between the lower part of the gauge and the endless belt above which this gauge is mounted.
- the cutouts of folding boxes are generally printed and, for folding requirements, the cutout is placed in the feeder so that the print is facing the endless belts.
- the lower cutout of the stack located in the feeder will necessarily rub with its unprinted side on the printed side of the next cutout.
- the introduction devices known to date therefore have certain drawbacks when introducing cutouts having printed surfaces very sensitive to scratches and to their degradation by friction.
- the use of a conventional gauge means that there is always a certain pressure, due to the weight of the stack of cuts placed in the feeder, between the bottom cut of the stack and the next cut. This pressure produces a detrimental effect during the introduction of cutouts whose impression is very fragile, for example when working cutouts which have undergone printing with inks which are polymerizable with ultra-violet rays or in the case of a printing with inks with the same resistance characteristics.
- the printing of the blanks is deteriorated to such an extent that the result results in the scrapping of the blanks of folding boxes thus worked.
- the present invention aims to remedy the aforementioned drawbacks.
- the invention consists of an introduction gauge according to what is stated in claim 1.
- FIG. 1 schematically represents an introduction device 1 comprising a feeder 2 comprising a series of endless belts 3 arranged side by side over the width of said feeder 2.
- the endless belts 3 are driven by a motor roller 4 placed at the front of the feeder and pass around a driven roller 5 located at the rear of the device.
- the upper strand 6 of each of the endless belts 3 is supported by rollers 7 mounted in a beam 8 disposed under each of said endless belts 3.
- a gauge 9 having a lower part 10 of rounded shape is mounted above and in the axis of one of the rollers or rollers supporting the endless belts 3.
- a clearance 11, corresponding substantially to the thickness of a cutout 12 is left between the rounded bottom portion 10 of the gauge 9 so as to allow passage of the cutout 13.
- the cutouts 12, respectively 13 are arranged in an inclined stack in the feeder 2 above the endless belts 3. Their front edge bears against the rounded part of the gauge and their rear part rests on supports 14.
- the feeder 2 is placed upstream of the transport member 15 of the machine working the cuts for example a folder gluer.
- Figure 2 illustrates the state of the art known to date for introducing cutouts 16, 17 having an imprint 18 on their underside.
- the cutout 16 is shown here at the time when it will be introduced into the machine. It will pass, under the effect of the drive by the endless belt 3, under the gauge 9 and its upper face 19, not printed, will rub during the entire insertion operation on the printed face 18 of the blank next 17.
- FIG. 3 represents the conditions of introduction prevailing when using an introduction gauge according to the invention.
- the gauge 20 is arranged so as to be able to authorize a supply of fluid at the end of its lower part.
- Figures 4 and 5 describe in detail the construction of this gauge.
- the cutout 21 in Figure 3 is driven under the gauge 20 by the endless belt 3, this without there being friction of its printed face 22 on the belts.
- a fluid 23, for example compressed air from a source (not shown), is constantly blown through the lower end of the gauge 20 on the unprinted face 24 of the cutout 21 and thus creates a flow of fluid , or even a fluid cushion, at the bottom of the gauge, flow or cushion of fluid which has the effect, inter alia, of eliminating the thermal effects of friction between the unprinted face of the cutout 21 and the printed face 25 of the next cutout 26, thereby avoiding any abrasion effect between the two cuts 21 and 26.
- the flow or cushion of fluid may even cause a total absence of contact between the two cuts 21 and 26.
- FIG 4 is a side view, in partial section of the gauge 20 of Figure 3.
- This gauge 20 of rectangular section is fixed, so that it can be adjusted vertically, against a crosspiece 27 extending between the two side frames (not shown) of feeder 2 using a special screw 28.
- the lower end of the gauge 20 has a straight surface 29 as well as a rounded part 30 connecting said straight surface 29 and the contact face 31 of the gauge.
- This same lower end of the gauge 20 has a bore 32 pierced right through the width of the gauge 20.
- Channels 33 for supplying fluid three in number in the present embodiment connect the bore 32 to the atmosphere by opening into the right surface 29.
- these fluid supply channels 33 are drilled along a perpendicular to the plane defined by the straight surface 29.
- the bore 32 is closed at one of its ends by a screw 34 provided with a seal 35 while its other end is equipped with a threaded connection 36 connected to the fluid supply pipe 37.
- three channels 33 are arranged in the lower end of the gauge 20. It is understood that depending on the characteristics of the prints made on the blanks or according to their grammage, one could imagine using a lower or higher number of channels 33.

Abstract
Description
La présente invention concerne une jauge d'introduction pour dispositif d'alimentation de découpes de boîtes pliantes, comportant un corps de jauge vertical, arrondi à sa partie inférieure, contre laquelle prennent appui les découpes de boîtes pliantes à introduire dans la machine les travaillant.The present invention relates to an introductory gauge for a device for supplying folding box blanks, comprising a vertical gauge body, rounded at its bottom, against which the folding box blanks are pressed to be introduced into the working machine.
Les dispositifs d'introduction de découpes de boîtes pliantes connus à ce jour, appelés communément margeurs par les praticiens, comportent généralement un organe de transport inférieur constitué par une série de courroies sans fin placées côte à côte dans la largeur du dispositif. Ces courroies sans fin sont entraînées par un rouleau moteur placé à l'avant du dispositif et passent ensuite autour d'un rouleau entraîné placé à l'arrière du dispositif précité. Le brin supérieur des courroies sans fin est en outre supporté par une série de galets de façon à constituer un plan de transport présentant une surface relativement rigide. Une jauge verticale est placée sensiblement dans l'axe du rouleau moteur et au-dessus de celui-ci. Les découpes de boîtes pliantes à introduire sont disposées de façon inclinée au-dessus des courroies sans fin, leur tranche avant venant s'appuyer contre une surface inclinée de la jauge alors que leur partie arrière repose sur des supports.The devices for introducing folding box blanks known to date, commonly called feeders by practitioners, generally include a lower transport member constituted by a series of endless belts placed side by side across the width of the device. These endless belts are driven by a drive roller placed at the front of the device and then pass around a driven roller placed at the rear of the aforementioned device. The upper strand of the endless belts is further supported by a series of rollers so as to constitute a transport plane having a relatively rigid surface. A vertical gauge is placed substantially in the axis of the driving roller and above it. The cutouts of folding boxes to be introduced are arranged in an inclined manner above the endless belts, their front edge coming to rest against an inclined surface of the gauge while their rear part rests on supports.
De préférence, deux jauges sont montées côte à côte dans la largeur du margeur. Afin d'autoriser le départ des découpes, un jeu correspondant sensiblement à l'épaisseur de la découpe à introduire est laissé entre la partie inférieure de la jauge et la courroie sans fin au-dessus de laquelle cette jauge est montée. Les découpes de boîtes pliantes sont en général imprimées et, pour des impératifs de pliage, la découpe est placée dans le margeur de telle façon que l'impression se trouve en regard des courroies sans fin. Lors de l'opération d'introduction, la découpe inférieure de la pile se trouvant dans le margeur va nécessairement frotter avec sa face non imprimée sur la face imprimée de la découpe suivante. Un tel dispositif est décrit plus en détail dans le brevet US-A-3 664 660.Preferably, two gauges are mounted side by side across the width of the feeder. To allow the cuts to start, a clearance corresponding substantially to the thickness of the cut to be introduced is left between the lower part of the gauge and the endless belt above which this gauge is mounted. The cutouts of folding boxes are generally printed and, for folding requirements, the cutout is placed in the feeder so that the print is facing the endless belts. During the insertion operation, the lower cutout of the stack located in the feeder will necessarily rub with its unprinted side on the printed side of the next cutout. Such a device is described in more detail in US-A-3,664,660.
De par leur conception, les dispositifs d'introduction connus à ce jour présentent donc certains inconvénients lors de l'introduction de découpes présentant des surfaces imprimées très sensibles aux rayures et à leur dégradation par frottement. En effet, l'utilisation d'une jauge conventionnelle fait qu'il existe toujours une certaine pression, due au poids de la pile de découpes placée dans le margeur, entre la découpe inférieure de la pile et la découpe suivante. Cette pression produit un effet néfaste lors de l'introduction de découpes dont l'impression est très fragile, par exemple lorsque l'on travaille des découpes ayant subit une impression avec des encres polymérisables aux rayons ultra-violets ou dans le cas d'une impression avec des encres présentant les mêmes caractéristiques de résistance. Avec une jauge conventionnelle, l'impression des découpes est détériorée à tel point que le résultat débouche sur la mise au rebut des découpes de boîtes pliantes ainsi travaillées.By their design, the introduction devices known to date therefore have certain drawbacks when introducing cutouts having printed surfaces very sensitive to scratches and to their degradation by friction. Indeed, the use of a conventional gauge means that there is always a certain pressure, due to the weight of the stack of cuts placed in the feeder, between the bottom cut of the stack and the next cut. This pressure produces a detrimental effect during the introduction of cutouts whose impression is very fragile, for example when working cutouts which have undergone printing with inks which are polymerizable with ultra-violet rays or in the case of a printing with inks with the same resistance characteristics. With a conventional gauge, the printing of the blanks is deteriorated to such an extent that the result results in the scrapping of the blanks of folding boxes thus worked.
La présente invention à pour but de remédier aux inconvénients précités.The present invention aims to remedy the aforementioned drawbacks.
A cet effet, l'invention consiste en une jauge d'introduction conforme à ce qu'énonce la revendication 1.To this end, the invention consists of an introduction gauge according to what is stated in claim 1.
Les avantages obtenus grâce à cette invention consistent essentiellement en ce que la détérioration de l'impression des découpes étant supprimée, le taux de découpes à mettre au rebut devient pratiquement nul et augmente de ce fait les caractéristiques de productivité de la machine travaillant les découpes.The advantages obtained thanks to this invention consist essentially in that the deterioration of the printing of the blanks being eliminated, the rate of blanks to be scrapped becomes practically zero and thereby increases the productivity characteristics of the machine working the blanks.
Un exemple de réalisation de la jauge d'introduction selon l'invention sera décrit en détail ci-après à titre d'exemple à l'aide du dessin annexé dans lequel :

- La figure 2 est une vue schématique représentant l'état de la technique,
- La figure 3 est une vue schématique représentant les conditions d'introduction d'une découpe à l'aide d'une jauge selon l'invention,
- La figure 4 est une vue de profil, en coupe partielle de la jauge de la figure 3 et
- La figure 5 est une vue en coupe partielle, selon X de la figure 4.
- FIG. 1 is a schematic view of an introduction device,
- FIG. 2 is a schematic view representing the state of the art,
- FIG. 3 is a schematic view showing the conditions for introducing a blank using a gauge according to the invention,
- FIG. 4 is a side view, in partial section of the gauge of FIG. 3 and

La figure 1 représente schématiquement un dispositif d'introduction 1 comprenant un margeur 2 comportant une série de courroies sans fin 3 disposées côte à côte sur la largeur dudit margeur 2. Les courroies sans fin 3 sont entraînées par un rouleau moteur 4 placé à l'avant du margeur et passent autour d'un rouleau entraîné 5 situé à l'arrière du dispositif. Le brin supérieur 6 de chacune des courroies sans fin 3 est supporté par des galets 7 montés dans un longeron 8 disposé sous chacune desdites courroies sans fin 3. Une jauge 9 comportant une partie inférieure 10 de forme arrondie est montée au-dessus et dans l'axe de l'un des rouleaux ou galets supportant les courroies sans fin 3. Un jeu 11, correspondant sensiblement à l'épaisseur d'une découpe 12 est laissé entre la partie inférieure 10 arrondie de la jauge 9 de façon à autoriser le passage de la découpe 13. Les découpes 12, respectivement 13 sont disposées en pile inclinée dans le margeur 2 au-dessus des courroies sans fin 3. Leur bord avant s'appuie contre la partie arrondie de la jauge et leur partie arrière repose sur des supports 14. Le margeur 2 est placé à l'amont de l'organe de transport 15 de la machine travaillant les découpes par exemple une plieuse colleuse.FIG. 1 schematically represents an introduction device 1 comprising a
La figure 2 illustre l'état de la technique connu à ce jour pour introduire des découpes 16, 17 comportant une impression 18 sur leur face inférieure. La découpe 16 est représentée ici à l'instant où elle va être introduite en machine. Elle va passer, sous l'effet de l'entraînement par la courroie sans fin 3, sous la jauge 9 et sa face supérieure 19, non imprimée, va frotter pendant toute l'opération d'introduction sur la face imprimée 18 de la découpe suivante 17.Figure 2 illustrates the state of the art known to date for introducing
La figure 3 représente les conditions d'introduction régnant lorsque l'on utilise une jauge d'introduction selon l'invention. Dans cette figure, la jauge 20 est agencée de façon à pouvoir autoriser une amenée de fluide à l'extrémité de sa partie inférieure. Les figures 4 et 5 décrivent en détail la réalisation de cette jauge.FIG. 3 represents the conditions of introduction prevailing when using an introduction gauge according to the invention. In this figure, the
La découpe 21 de la figure 3 est entraînée sous la jauge 20 par la courroie sans fin 3, cela sans qu'il y ait frottement de sa face imprimée 22 sur les courroies. Un fluide 23, par exemple de l'air comprimé provenant d'une source (non représentée), est constamment insufflé par l'extrémité inférieure de la jauge 20 sur la face non imprimée 24 de la découpe 21 et crée ainsi un flux de fluide, voire un coussin de fluide, au niveau de la partie inférieure de la jauge, flux ou coussin de fluide qui a entre autres pour effet d'éliminer les effets thermiques du frottement entre la face non imprimée de la découpe 21 et la face imprimée 25 de la découpe suivante 26 , évitant de ce fait tout effet d'abrasion entre les deux découpes 21 et 26. Dans certains cas par exemple lorsque l'on travaille des découpes de petit format en piles peu importantes et avec une pression de fluide élevée, le flux ou coussin de fluide pourra même provoquer une absence totale de contact entre les deux découpes 21 et 26.The
La figure 4 est une vue de profil, en coupe partielle de la jauge 20 de la figure 3. Cette jauge 20 de section rectangulaire est fixée, de manière à pouvoir être réglée verticalement, contre une traverse 27 s'étendant entre les deux bâtis latéraux (non représentés) du margeur 2 à l'aide d'une vis spéciale 28.Figure 4 is a side view, in partial section of the
L'extrémité inférieure de la jauge 20 présente une surface droite 29 ainsi qu'une partie arrondie 30 raccordant ladite surface droite 29 et la face de contact 31 de la jauge. Cette même extrémité inférieure de la jauge 20 possède un alésage 32 percé de part en part de la largeur de la jauge 20. Des canaux 33 d'amenée de fluide, au nombre de trois dans la présente exécution relient l'alésage 32 à l'atmosphère en débouchant dans la surface droite 29.
De préférence, ces canaux 33 d'amenée de fluide sont percés suivant une perpendiculaire au plan défini par la surface droite 29.The lower end of the

Dans l'exécution représentée par la figure 5, l'alésage 32 est obturé à l'une de ses extrémités par une vis 34 munie d'un joint d'étanchéité 35 alors que son autre extrémité est équipée d'un raccord fileté 36 relié au tuyau 37 d'amenée de fluide. Dans l'exécution représentée trois canaux 33 sont aménagés dans l'extrémité inférieure de la jauge 20.
Il est bien entendu qu'en fonction des caractéristiques des impressions réalisées sur les découpes ou en fonction de leur grammage, on pourrait imaginer d'utiliser un nombre inférieur ou supérieur de canaux 33.In the embodiment shown in Figure 5, the
