Description

L'invention concerne des moyens d'ensachage de plusieurs compresses, pliees ainsi que le sachet obtenu.The invention relates to bagging means for several compresses, folded as well as the sachet obtained.

L'objet de l'invention se rattache aux secteurs techniques de la manipulation des matériaux en bandes ainsi que de leur conditionnement.The object of the invention relates to the technical sectors of the handling of materials in strips as well as their packaging.

On connait des machines exécutant en continu et de manière automatique des compresses pliées à partir de bobines. C'est le cas notamment de la machine ayant fait l'objet du brevet français n° 81.00687 dont le déposant est également le Titulaire.There are known machines which continuously and automatically fold compresses from coils. This is particularly the case for the machine which has been the subject of French patent n ° 81.00687, the applicant of which is also the Holder.

Ces compresses pliées doivent ensuite être conditionnées soit dans des boîtes, soit dans des sachets. l'ensachage s'opère généralement par scellage à chaud à l'aide d'outils appropriés (molettes, rouleaux...) ce qui implique une certaine lenteur (pression, température...). D'autre part, les compresses amenées depuis le poste de pliage, sont empilées les unes sur les autres, en vue de l'ensachage, avec donc une épaisseur relativement importante qui peut nuire à la fermeture du sachet obtenu par rapprochement et soudure de deux feuilles de papier entre lesquelles sont empilées les compresses.These folded compresses must then be packaged either in boxes or in sachets. bagging is generally carried out by heat sealing using appropriate tools (knobs, rollers, etc.), which implies a certain slowness (pressure, temperature, etc.). On the other hand, the compresses brought from the folding station are stacked on top of each other, for bagging, with a relatively large thickness which can hinder the closing of the bag obtained by bringing together and welding two sheets of paper between which the compresses are stacked.

C'est pour éviter ces inconvénients et assurer un conditionnement rapide et étanche des compresses pliées, avec un encombrement minimum, que l'on propose selon l'invention de réaliser un empilage , en "tuile" des compresses et un scellage à froid des feuilles de papier d'ensachage.It is to avoid these drawbacks and to ensure rapid and leaktight packaging of the folded compresses, with a minimum bulk, that it is proposed according to the invention to make a stack, in "tile" of the compresses and a cold sealing of the sheets. bagging paper.

On connait par le brevet US 4,085,560 un procedé d'ensachage de compresses dans lequel on utilise un papier présenté en bobine de largeur double du sachet a obtenir, on sépare en deux largeurs égales la bande déroulée, on fait cheminer indépendamment les deux longeurs jusqu'au niveau ou sont amenées les compresses pliées, on fait avancer les compresses empilées entre les deux largeurs de papier, puis on réalise le scellage a froid des deux largeurs superposées et la coupe transversale des sachets obtenus, tout cela en continu et de manière automatique.We know from US Pat. No. 4,085,560 a process for bagging compresses in which a paper presented in a reel of double width of the sachet to be obtained is used, the unwound strip is separated into two equal widths, the two lengths are made to run independently up to at the level where the folded compresses are brought, the compresses stacked between the two widths of paper are advanced, then the cold sealing of the two overlapping widths is carried out and the cross-section of the sachets obtained, all of this continuously and automatically.

Suivant l'invention la mise en oeuvre du procédé d'ensachage de compresses pliees s'effectue par un positionnement en décalage longitudinal pour realiser un empilage en tuiles des compresses, les moyens d ensachage etant tels que l'introduction en décalage longitudinal des compresses pliées entre les couples de demi-largeur de papier est obtenue par les cylindres presseurs et entraineurs des couples de demi-largeur de papier, qui sont montés à oscillation de telle sorte que par rapprochement du cylindre supérieur d'entrainement d'une demi-largeur de papier contre le cylindre inférieur, l'extrémité d'une compresse soit pincée et engagée entre les deux demi-largeurs superposées, puis par plaquage de la compresse sur le cylindre inférieur, abaissement de la compresse sur le cylindre inférieur, et écartement du cylindre supérieur, de façon que la compresse suivante puisse se présenter à son tour pour être pincée par rapprochement du cylindre supérieur avec un décalage par rapport à la précédente selon une presentation en tuiles du fait de l'avance continue des cylindres entrainant les deux demi-largeurs de papier et la compresse engagée.According to the invention, the implementation of the bagging process for folded compresses is carried out by positioning in longitudinal offset to make a stack of compresses in tiles, the bagging means being such as the introduction in longitudinal offset of the folded compresses. between the half-width pairs of paper is obtained by the pressing and driving cylinders of the half-width pairs of paper, which are mounted to oscillate so that by bringing the upper drive cylinder half-width apart paper against the lower cylinder, the end of a compress is pinched and engaged between the two superimposed half-widths, then by pressing the compress on the lower cylinder, lowering the compress on the lower cylinder, and spacing the upper cylinder , so that the next pad can be presented in turn to be pinched by bringing the upper cylinder together with an offset age compared to the previous one in a tiled presentation due to the continuous advance of the cylinders driving the two half-widths of paper and the compress engaged.

Ces caractéristiques et d'autres ressortiront de la suite de la description.These characteristics and others will emerge from the following description.

To fix the subject of the invention without however the limit, in the attached drawings:
  • Figure 1 is a very schematic perspective view illustrating the bagging process.
  • Figure 2 is a front view of a thematic character illustrating the introduction of compresses between the paper strips.
  • Figures 3 to 6 show by partial and very schematic views the main phases of bagging in "tile" compresses.
  • Figure 7 is a plan view showing the bagged compresses.

Afin de rendre plus concret l'objet de l'invention on le décrit maintenant sous une forme non limitative de réalisation illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting embodiment illustrated in the figures of the drawings.

L'installation d'ensachage selon l'invention est adaptée à la suite d'une machine de distribution de bandes enroulées et coupées à la longueur puis pliées pour constituer des compresses qui sont alors guidées entre deux grilles sur un tapis transporteur à courroies multiples (T). C'est à partir de la qu'intervient l'installation d'ensachage.The bagging installation according to the invention is adapted following a machine for distributing rolled up strips cut to length then folded to form compresses which are then guided between two grids on a conveyor belt with multiple belts ( T). This is where the bagging system comes in.

Pour cela, une bâti approprié (non représenté) porte les différents organes nécessaires à cette opération. En premier lieu, on trouve un axe (1) fixé transversaledment a l'extérieur du bâti. Sur cet axe est montée une bobine (B) de papier comprenant par exemple une demi-largeur (B1) vierge et une demi-largeur (B2) imprimée sur la face apparente.For this, an appropriate frame (not shown) carries the various organs necessary for this operation. First, there is an axis (1) fixed transversely to the outside of the frame. On this axis is mounted a reel (B) of paper comprising for example a half-width (B1) blank and a half-width (B2) printed on the visible face.

La bande de papier déroulée avec sa face apparente complètement vierge passe par des groupes de rouleaux de renvoi et de tension (2), (3), (4), et (5), (6), (7) associés au bâti. Entre ces deux groupes de rouleaux, la bande est coupée longitudinalement en deux demi-largeurs égales correspondant à la partie vierge et à la partie imprimée, par un dispositif de coupe par pression (L) par exemple à l'aide d'un disque à bord coupant sur un cylindre trempé. En même temps, on amorce une découpe (B3) pour faciliter l'ouverture ultérieure du sachet ; cette découpe étant achevée lors de la coupe transversale des sachets.The strip of paper unrolled with its completely blank visible face passes through groups of deflection and tension rollers (2), (3), (4), and (5), (6), (7) associated with the frame. Between these two groups of rollers, the strip is cut longitudinally into two equal half-widths corresponding to the blank part and the printed part, by a pressure cutting device (L) for example using a disc with cutting edge on a hardened cylinder. At the same time, a cutout (B3) is started to facilitate the subsequent opening of the sachet; this cutting being completed during the transverse cutting of the sachets.

A la sortie du rouleau (7), la demi-largeur (B1) vierge est dirigée en partie basse directement vers une barre (8) montée à articulation sur le bâti et s'étendant selon un angle de 45° par rapport au sens d'arrivée de ladite demi-largeur, afin de permettre son défilement selon une direction longitudinale au bâti. Après passage sur un autre groupe de rouleaux de renvoi (9), (10), (11), la demi-largeur (B1) s'enroule sur un cylindre inférieur (12) disposé transversalement en bout du tapis transporteur (T) et repart horizontalement en sens inverse en direction de l'extrémité libre du bâti.At the exit of the roller (7), the virgin half-width (B1) is directed in the lower part directly towards a bar (8) mounted at articulation on the frame and extending at an angle of 45 ° relative to the direction d arrival of said half-width, in order to allow it to travel in a longitudinal direction to the frame. After passing over another group of deflection rollers (9), (10), (11), the half-width (B1) is wound on a lower cylinder (12) arranged transversely at the end of the conveyor belt (T) and departs horizontally in the opposite direction towards the free end of the frame.

L'autre demi-largeur (B2) imprimée, à la sortie du rouleau (7) est dirigée verticalement à la partie supérieure du bâti, s'enroule sur un rouleau de renvoi (13) pour rejoindre horizontalement une deuxième barre (14) de changement de direction identique à la barre (8) mais inclinée a 45° de manière inverse, afin de diriger la demi-largeur (B2) vers l'extrémité libre du bâti où elle s'enroule sur un rouleau de renvoi (15) pour revenir vers l'arrière du bâti en passant par des rouleaux de renvoi et de changement d'orientation (16), (17) amenant la demi-largeur vers un cylindre supérieur (18) disposé en bout du tapis transporteur (T) et en avant du cylindre inférieur (12).The other half-width (B2) printed, at the outlet of the roller (7) is directed vertically to the upper part of the frame, is wound on a deflection roller (13) to join horizontally a second bar (14) of change of direction identical to the bar (8) but inclined at 45 ° in reverse, in order to direct the half-width (B2) towards the free end of the frame where it is wound on a deflection roller (15) to return towards the rear of the frame by passing through return and orientation change rollers (16), (17) bringing the half-width towards an upper cylinder (18) disposed at the end of the conveyor belt (T) and front of the lower cylinder (12).

La demi-largeur (B2) enroulée sur ledit cylindre (18) repart ensuite horizontalement vers l'extrémité libre du bâti en étant superposée à la demi-largeur (B1) et en laissant entre elles un espace (e) permettant l'introduction des compresses.The half-width (B2) wound on said cylinder (18) then departs horizontally towards the free end of the frame by being superimposed on the half-width (B1) and leaving between them a space (e) allowing the introduction of compresses.

A noter que la face imprimée de la demi-largeur (B2) est alors située sur le dessus compte tenu des différentes orientations.Note that the printed side of the half-width (B2) is then located on the top taking into account the different orientations.

L'entrainement en continu des demi-largeurs (B1), (B2) est assuré par les cylindres (12) (18) qui sont reliés de manière connue à des organes moteurs avec variation de vitesse, embrayage différentiel et autres dispositifs nécessaires dans le processus d'ensachage. De même, les demi-largeurs (B1) (B2) après leur enroulement sur les cylindres (12), (18) sont entrainées en continu par les outils de scellage à froid des deux demi-largeurs qui sont montés a rotation sur la bâti, a savoir : un cylindre moleté (19) pour le scellage transversal entre les paquets de compresses et des molettes latérales (20) (21) pour le scellage longitudinal des bords. Les sachets (S) ainsi formés sont séparés de manière classique par un outil de coupe transversal (22) terminant la découpe (B3) et acheminés vers un moyen de conditionnement quelconque.The continuous driving of the half-widths (B1), (B2) is ensured by the cylinders (12) (18) which are connected in known manner to the drive members with speed variation, differential clutch and other devices necessary in the bagging process. Similarly, the half-widths (B1) (B2) after their winding on the cylinders (12), (18) are driven in continuous by the cold sealing tools of the two half-widths which are rotatably mounted on the frame, namely: a knurled cylinder (19) for the transverse sealing between the packs of compresses and lateral knurls (20) (21) for longitudinal sealing of edges. The bags (S) thus formed are conventionally separated by a transverse cutting tool (22) terminating the cutting (B3) and conveyed to any packaging means.

A noter que le papier utilisé est du type préencollé et selon lequel lorsqu'on ouvre le sachet, la colle se retrouve d'un seul côté afin d'éviter une réutilisation du sachet. Ce type de sachet est communément appelé "sachet pelable".Note that the paper used is of the pre-glued type and according to which when the bag is opened, the glue is found on one side only to avoid re-use of the bag. This type of sachet is commonly called "peelable sachet".

L'entrainement des demi-largeurs (B1), (B2) doit être effectué en tension constante. Pour cela, les barres inclinées (8), (14) sont montés d'une manière particulière.The training of the half-widths (B1), (B2) must be carried out at constant voltage. For this, the inclined bars (8), (14) are mounted in a particular way.

Le cylindre supérieur (18) est monté sur des bras latéraux (23) articulés sur un axe (24) qui porte lui-même par des barrettes (25) le rouleau de tension (17) appliqué sur la demi-largeur (B2).The upper cylinder (18) is mounted on lateral arms (23) articulated on an axis (24) which itself carries by bars (25) the tension roller (17) applied over the half-width (B2).

Le cylindre inférieur (12) est également porté par des bras latéraux (26) articulés sur le rouleau (11) et dont l'autre extrémité porte le rouleau (10).The lower cylinder (12) is also carried by lateral arms (26) articulated on the roller (11) and the other end of which carries the roller (10).

Lorsque les compresses (C) pliées et guidées sur le tapis transporteur (T) butent contre le cylindre inférieur (12) en position haute, le cylindre supérieur (18) qui a précédement été écarté, est alors rapproché (flèche F1, figure 3) du cylindre inférieur pour pincer l'extrémité avant de la compresse ; les demi-largeurs continuant d'avancer, la compresse est engagée entre les deux cylindres. A ce moment, un volet mobile (27) situé au-dessus du cylindre supérieur (18) est basculé vers le bas (Flèche F2, figure 4) pour appliquer la compresse sur le cylindre inférieur (12) et ainsi dégager le passage pour la compresse suivante par rélevage de volet.When the compresses (C) folded and guided on the conveyor belt (T) abut against the lower cylinder (12) in the high position, the upper cylinder (18) which was previously discarded, is then brought together (arrow F1, Figure 3) the lower cylinder to pinch the front end of the compress; the half-widths continuing to advance, the compress is engaged between the two cylinders. At this time, a movable flap (27) located above the upper cylinder (18) is tilted down (Arrow F2, Figure 4) to apply the compress to the lower cylinder (12) and thus clear the passage for the next compress by raising the flap.

Le cylindre inférieur (12) est alors abaissé de la vaieur de l'épaisseur de la compresse, tandis que le cylindre supérieur (18) est ramené en position d'écartement (flèche F3, figure 5) en permettant l'arrivée en butée d'une autre compresse. Compte tenu de l'avancement en continu des demi-largeurs (B1), (B2) les compresses suivantes seront introduites entre lesdites demi-largeurs avec un décalage (d). Cette disposition dite "en tuiles" des compresses superposées permettent de réaliser un empilage de faible épaisseur, aidé en cela par l'écrasement de la compresse aux pliures effectué par le poste de pliage en amont. De ce fait, le scellage à froid est facilité et on évite les risques de points ou zones non scellés comme cela est le cas avec le dispositif selon l'art antérieur.The lower cylinder (12) is then lowered by the thickness of the compress, while the cylinder upper (18) is returned to the spacing position (arrow F3, Figure 5) allowing the abutment of another pad. Given the continuous advancement of the half-widths (B1), (B2) the following pads will be introduced between said half-widths with an offset (d). This so-called "tiled" arrangement of the superimposed pads makes it possible to produce a stacking of small thickness, aided by the crushing of the folded pad made by the upstream folding station. As a result, cold sealing is facilitated and the risks of unsealed spots or areas are avoided, as is the case with the device according to the prior art.

A noter que le nombre de compresses ensachées est librement déterminé et commandé par un compteur à préselection.Note that the number of bagged compresses is freely determined and controlled by a preset counter.

Entre chaque paquet de compresses empilées, les demi-largeurs de papier sont avancées plus rapidement (par le différentiele et l'embrayage).Between each pack of compresses stacked, the half-widths of paper are advanced more quickly (by the differential and the clutch).

D'autre part, le cadrage de l'impression et des zones encollées, ainsi que la superposition exacte des demi-largeurs sont assurés par des moyens détecteurs (symbolisés par le repère (D), disposés latéralement à la sortie des cylindres (12), (18) et agissant en fonction de repères sur le papier.
   les avantages ressortent bien de la description, on souligne encore la rapidité d'ensachage, l'épaisseur réduite des sachets, et la possibilité d'utiliser des papiers imprimés.On the other hand, the framing of the print and of the glued areas, as well as the exact superimposition of the half-widths are ensured by detector means (symbolized by the mark (D), arranged laterally at the outlet of the cylinders (12) , (18) and acting according to marks on the paper.
the advantages clearly emerge from the description, the speed of bagging, the reduced thickness of the sachets and the possibility of using printed papers are also emphasized.
