Machine à façonner les soufflets de fond
des enveloppes, des sachets et sacs en papier
comportant en tout trois soufflets
La présente invention concerne une machine à façonner les soufflets de fond des enveloppes, sachets et sacs en papier comportant trois soufflets.Antoine CHANDELLIER

Bottom gusset forming machine
envelopes, sachets and paper bags
comprising a total of three bellows
The present invention relates to a machine for shaping the bottom bellows of envelopes, sachets and paper bags comprising three bellows.

Actuellement, les soufflets de fond sont réalisés souvent en partie manuellement et ces enveloppes ou sacs sont alors nettement plus onéreux que les articles à deux soufflets longitudinaux. Currently, the bottom bellows are often made partly manually and these envelopes or bags are then much more expensive than articles with two longitudinal bellows.

La présente invention pennet de remédier à cet inconvénient. Elle concerne une machine pouvant faire automatiquement les pliages et collages nécessaires pour façonner le soufflet de fond. Elle comprend deux rampes de ventouses qui permettent d'aspirer les extrémités des parties supérieures et inférieures de l'enveloppe ou du sac qui a été préalablement collé longitudinalement et muni de soufflets latéraux et longitudinaux selon les procédés actuellement connus. Cette machine comprend également des vérins alternatifs actionnant des lamelles provoquant le rabattement des volets latéraux, puis du volet inférieur, et enfin du volet supérieur lorsque les extrémités de l'enveloppe sont aspirées et bien maintenues par les rampes de ventouses précitées.Elle comprend un rouleau encolleur qui peut être animé d'un mouvement alternatif transversal et une lamelle jouant le rôle de pince Juste en avant de la rampe supérieure de ventouses. Les mouvements conJugués de cette pince et de la lamelle de rabattement du volet supérieur permettent de plier facilement et rapidement le soufflet de fond. The present invention makes it possible to remedy this drawback. It concerns a machine that can automatically make the folds and glues necessary to shape the bottom gusset. It comprises two ramps of suction cups which make it possible to suck the ends of the upper and lower parts of the envelope or of the bag which has been previously glued longitudinally and provided with lateral and longitudinal bellows according to the methods currently known. This machine also includes reciprocating cylinders actuating slats causing the folding of the side flaps, then of the lower flap, and finally of the upper flap when the ends of the envelope are sucked and well maintained by the aforementioned suction cup ramps. It includes a roller glue which can be animated with a transverse reciprocating movement and a lamella acting as a clamp Just in front of the upper ramp of suction cups. The combined movements of these pliers and the top flap folding plate allow the bottom gusset to be folded easily and quickly.

- Les dessins annexés illustrent l'invention. La figure 1 représente, en coupe longitudinale, la machine revendiquée lorsque les extrémités de l'enveloppe ou du sac sont aspirées par les ventouses.- The accompanying drawings illustrate the invention. Figure 1 shows, in longitudinal section, the claimed machine when the ends of the envelope or bag are sucked by the suction cups.

- La figure 2 représente, touJours en coupe longitudinale, la même machine, mais au moment du pliage du soufflet de fond.- Figure 2 shows, always in longitudinal section, the same machine, but at the time of folding of the bottom gusset.

- La figure 3 représente la machine vue de face, sur un côté seulement.- Figure 3 shows the machine front view, on one side only.

L'autre côté comporte les mêmes éléments symétriquement par rapport à l'axe longitudinal de la machine.The other side has the same elements symmetrically with respect to the longitudinal axis of the machine.

- La figure 4 représente, en perspective, l'enveloppe ou sac muni d'un collage longitudinal et de deux soufflets longitudinaux avant d'être mis dans la machine qui façonnera le troisième soufflet et qui est présentement revendiquée.- Figure 4 shows, in perspective, the envelope or bag provided with a longitudinal bonding and two longitudinal bellows before being put into the machine which will shape the third bellows and which is currently claimed.

La machine représentée sur la figure 1 comporte un support (1) sur lequel est disposé l'enveloppe ou le sac à façonner, deux rampes de ven touses fixes (3) et (4) placées face à face qui permettent d'aspirer les parties supérieures et inférieures et de les maintenir sans déformation pendant le rabattement des volets, au moyen des lamelles qui peuvent toutes être munies d'un mouvement rectiligne alternatif grâce à des vérins pneumatiques. L'espacement vertical des rampes de ventouses horizontales (3) et (4) est égal à la hauteur du soufflet de l'envelop- pe. La longueur des rampes (3) et (4) est égale à la largeur de ltenve- loppe à façonner. Les lamelles latérales (9) sont disposées Juste devant les éléments (3) et (4).Elles sont actionnées par des vérins al ternatifs. Ces lamelles (9) rabattent les volets latéraux de l'envelop- pe. La lamelle (5) verticale est disposée Juste devant (9). La lamelle (6) est disposée en aval de (5) et permet de rabattre le volet supérieur (7). Elle est horizontale et est disposée au-dessus de (7). Elle est mue obliquement par un vérin (11) incliné. Cette lamelle (6) permet de plier le volet supérieur (7) qui vient sur (8) préalablement rabattu verticalement. La machine comprend aussi une roulette (10) placée devant (5). Cette roulette peut être actionnée transversalement par un vérin et peut encoller la partie inférieure de (7). Une pince (2) peut s'abaisser sur (1) au moyen d'un vérin alternatif. Cette pince (2) est disposée Juste devant la rampe de ventouses (3).The machine shown in FIG. 1 comprises a support (1) on which the envelope or the shaping bag is placed, two fixed ramps (3) and (4) placed face to face which make it possible to vacuum the parts upper and lower and maintain them without deformation during the folding of the flaps, by means of the slats which can all be provided with an alternating rectilinear movement by means of pneumatic cylinders. The vertical spacing of the horizontal suction cup ramps (3) and (4) is equal to the height of the bellows of the enclosure. The length of the ramps (3) and (4) is equal to the width of the hood to be shaped. The side slats (9) are arranged Just in front of the elements (3) and (4). They are actuated by alternating cylinders. These strips (9) fold the side flaps of the envelope. The vertical strip (5) is arranged Just in front (9). The strip (6) is disposed downstream of (5) and allows the upper flap (7) to be folded down. It is horizontal and is arranged above (7). It is moved obliquely by an inclined jack (11). This strip (6) makes it possible to fold the upper flap (7) which comes on (8) previously folded vertically. The machine also includes a caster (10) placed in front (5). This roller can be actuated transversely by a jack and can glue the lower part of (7). A clamp (2) can be lowered onto (1) by means of an alternative cylinder. This clamp (2) is arranged Just in front of the suction cup ramp (3).

La figure 2 représente le mouvement conJugué de la pince (2) et de la lamelle (6) qui permet le pliement du soufflet de fond et le collage des rabats.FIG. 2 represents the combined movement of the clamp (2) and the strip (6) which allows the folding of the bottom bellows and the bonding of the flaps.

Sur la figure 3, les rampes de ventouses horizontales (3) et (4) sont prolongées verticalement en (13), ce qui permet de bien maintenir les côtés verticaux-des enveloppes ou sacs pendant le rabattement des volets latéraux par les lamelles (9).In FIG. 3, the ramps of horizontal suction cups (3) and (4) are extended vertically at (13), which allows the vertical sides-of the envelopes or bags to be properly maintained during the folding of the side flaps by the slats (9 ).

Sur la figure 4, la référence (15) désigne le collage longitudinal de l'enveloppe et (14) un rainage transversal réalisé par tout moyen connu. Ce rainage n' est pas indispensable mais facilite beaucoup les opérations de pliement des lamelles. Sa référence (16) désigne les soufflets latéraux déjà exécutés.In FIG. 4, the reference (15) designates the longitudinal bonding of the envelope and (14) a transverse creasing produced by any known means. This creasing is not essential but greatly facilitates the folding operations of the slats. Its reference (16) designates the side bellows already executed.

Le fonctionnement de la machine est décrit ci-après - L'enveloppe ou le sac est tout d'abord muni de deux soufflets latéraux (16) et longitudinaux par tout moyen connu. En outre, elle est collée suivant (15).The operation of the machine is described below - The envelope or the bag is first of all provided with two lateral (16) and longitudinal bellows by any known means. In addition, it is pasted according (15).

- Elle est alors mise sur le support (1) de façon à ce que sa partie située Juste devant le rainage (14) soit disposée sous les rampes (3) et (4). Le rainage (14) étant exécuté à une distance de l'extrémité de l'enveloppe égale à la hauteur du soufflet moins deux à quatre millimètres. La pompe à vide actionnant les ventouses (3), (lui) et (13) est alors mise en marche et les parties extrêmes (7) et (8) supérieures et inférieures sont aspirées. A ce moment, la pince (2) est en position haute. Les lamelles latérales (9) rabattent les volets latéraux, puis la lamelle (5) rabat verticalement le volet (8), le rouleau (10) encolle (7). Puis l'aspiration en (3) est coupée. La lamelle (6) vient obliquement rabattre (7) tandis que la pince (2) vient sur (1). Le mouvement conJugué de ces deux éléments permet, d'une part de plier le soufflet de fond et, d'autre part, le collage de (7) sur les autres rabats.- It is then placed on the support (1) so that its part located just in front of the creasing (14) is arranged under the ramps (3) and (4). The creasing (14) being carried out at a distance from the end of the envelope equal to the height of the bellows minus two to four millimeters. The vacuum pump actuating the suction cups (3), (him) and (13) is then started and the upper and lower end parts (7) and (8) are sucked. At this time, the clamp (2) is in the high position. The lateral strips (9) fold the side flaps, then the strip (5) folds the flap (8) vertically, the roller (10) glues (7). Then the suction in (3) is cut off. The strip (6) is obliquely folded (7) while the clamp (2) comes on (1). The combined movement of these two elements allows, on the one hand to fold the bottom gusset and, on the other hand, the bonding of (7) on the other flaps.

L'aspiration en (4) est alors coupée et l'aspiration est terminée.The suction in (4) is then cut off and the suction is finished.

Les mouvements des vérins pneumatiques actionnant les lamelles sont commandés automatiquement par un système programmé électrique de façon à ce que les mouvements des différents éléments se produisent selon le processus décrit ci-dessus.The movements of the pneumatic cylinders actuating the slats are controlled automatically by a programmed electrical system so that the movements of the various elements occur according to the process described above.

Selon une variante, les vérins pneumatiques peuvent être remplacés par des systèmes d'arbres à cames synchronisés entre eux.Alternatively, the pneumatic cylinders can be replaced by camshaft systems synchronized with each other.

La machine revendiquée peut être utilisée pour faire les soufflets de fond des enveloppes, des sachets et sacs en papier.The claimed machine can be used to make the bottom gussets of envelopes, sachets and paper bags.

Bien entendu, la présente invention s'applique à tout mode de réalisation qui ne serait qu'un équivalent technique. Of course, the present invention applies to any embodiment which would only be a technical equivalent.
