Description

La présente invention concerne une découpe pour la réalisation d'un récipient parallélépipédique ouvert à son extrémité supérieure tel qu'un plateau pour fruits et légumes et qui est du type constitué d'un flan de carton découpé et rainé et comportant aux arêtes verticales du récipient des renforts verticaux intérieurs.The present invention relates to a blank for making a rectangular container open at its upper end such as a fruit and vegetable tray and which is of the type consisting of a blank of cardboard cut and grooved and comprising the vertical edges of the container interior vertical reinforcements.

Dans les découpes connues de ce type, le flan de carton découpé et rainé forme le fond et deux parois verticales du récipient à former. Les renforts sont reliés par paires entre eux pour former les deux autres parois verticales opposées du récipient. Ils sont le plus souvent reliés entre eux par des bandes de bois déroulées pour augmenter la rigidité du récipient obtenu. Une telle structure est complexe car le récipient doit être assemblé à partir de trois pièces séparées et cet assemblage est long et coûteux et se prête difficilement à une mécanisation sur des machines travaillant à des vitesses élevées.In known cuts of this type, the cut and creased cardboard blank forms the bottom and two vertical walls of the container to be formed. The reinforcements are connected in pairs with each other to form the other two opposite vertical walls of the container. They are most often connected together by strips of unrolled wood to increase the rigidity of the container obtained. Such a structure is complex because the container must be assembled from three separate parts and this assembly is long and expensive and is difficult to mechanize on machines working at high speeds.

La présente invention a pour objet de concevoir une découpe dudit type dont l'assemblage est facile et rapide et peut être mis en oeuvre à l'aide de dispositifs automatiques travaillant à des cadences élevées.The object of the present invention is to design a cutout of said type, the assembly of which is easy and rapid and can be implemented using automatic devices working at high rates.

Suivant la présente invention, ledit flan de carton se présente sous forme d'une seule pièce comportant toutes les parties destinées à former le fond et les parois verticales ainsi que les pattes de scellage du récipient, lesdits renforts étant fixés sur ledit flan lorsque celui-ci s'étend à plat dans un plan horizontal avant la mise en forme du récipient à former.According to the present invention, said cardboard blank is in the form of a single piece comprising all the parts intended to form the bottom and the vertical walls as well as the sealing tabs of the container, said reinforcements being fixed to said blank when the latter ci extends flat in a horizontal plane before the forming of the container to be formed.

On obtient ainsi une découpe constituée d'une seule pièce et dont les renforts sont fixés à plat sur le flan de carton. Cette découpe peut être manipulée et transportée à plat et être mise en forme seulement au moment de son utilisation par simple pliage et scellage.A cut is thus obtained consisting of a single piece and the reinforcements are fixed flat on the cardboard blank. This cutout can be handled and transported flat and be shaped only at the time of use by simple folding and sealing.

De préférence, la partie du flan de carton comporte en regard des extrémités voisines des renforts, des parties ajourées dont la section correspond sensiblement à celle des renforts, ces derniers s'étendant au-delà des bords extérieurs ou supérieurs des parties du flan destinées à former les parois verticales du récipient.Preferably, the part of the cardboard blank comprises, opposite the neighboring ends of the reinforcements, perforated parts whose section corresponds substantially to that of the reinforcements, the latter extending beyond the outer or upper edges of the parts of the blank intended to form the vertical walls of the container.

Ceci facilité l'empilage des récipients les uns' sur les. autres.This ease of stacking containers one 'on. other.

La présente invention concerne également un procédé pour l'assemblage des découpes selon l'invention.The present invention also relates to a method for assembling the blanks according to the invention.

Le procédé selon la présente invention consiste à déposer les renforts dans des positions prédéterminées sur un transporteur horizontal en mouvement, à déposer sur la face supérieure de chaque renfort une couche d'une matière adhésive, à déposer sur l'ensemble des renforts encollés ladite découpe découpée et rainée et à soulever la partie destinée à former le fond du récipient à former en direction verticale de sorte que les parties de la découpe portant les renforts soient rabàttues vers le bas sous l'action de la gravité, à replier les deux autres parties de la découpe et à sceller les pattes sur les premièresdites parties en maintenant les parties en une position verticale perpendiculaire au plan de la partie formant le fond du récipient.The method according to the present invention consists in depositing the reinforcements in predetermined positions on a horizontal conveyor in motion, depositing on the upper face of each reinforcement a layer of adhesive material, depositing on all of the adhesive reinforcements said cut and grooved cutout and lifting the part intended to form the bottom of the container to be formed in a vertical direction so that the parts of the cutout carrying the reinforcements are folded down under the action of gravity, folding the other two parts of the cutout and sealing the tabs on the first said parts by keeping the parts in a vertical position perpendicular to the plane of the part forming the bottom of the container.

L'assemblage peut ainsi être effectué d'une manière continue sans manipulations complexes du flan de carton et des renforts. De même, la mise en forme de la découpe pour former le récipient est une opération simple et rapide.The assembly can thus be carried out continuously without complex manipulations of the cardboard blank and the reinforcements. Likewise, shaping the cutout to form the container is a simple and rapid operation.

D'autres réalisations et avantages de l'invention ressortiront de la description qui va suivre et en se référant aux dessins annexés sur lesquels :

  • la figure *1 est une vue en plan d'un mode de réalisation préféré de la découpe selon l'invention,
  • les figures 2 à 5 sont des vues en élévation latérale schématiques montrant les phases essentielles du procédé selon l'invention pour la mise en forme de la découpe selon l'invention.
Other embodiments and advantages of the invention will emerge from the description which follows and with reference to the appended drawings in which:
  • FIG. 1 is a plan view of a preferred embodiment of the blank according to the invention,
  • Figures 2 to 5 are schematic side elevational views showing the essential phases of the method according to the invention for shaping the blank according to the invention.

La découpe selon l'invention représentée à la figure 1 est constituée d'une découpe de carton, par exemple en carton ondulé, portant la référence générale (1) et qui est réalisée en une seule pièce par découpage à partir d'un plan de carton rectangulaire.The blank according to the invention represented in FIG. 1 consists of a board blank, for example of corrugated board, bearing the general reference (1) and which is produced in one piece by cutting from a plane of rectangular cardboard.

La découpe (1) comprend une partie centrale (2) destinée à former le fond du récipient à former, deux parties (3) formant les parois verticales longitudinales et deux parties (4) formant les parois verticales transversales du récipient à former. Chaque partie (3) comporte, de plus, deux pattes de scellage (5) permettant de lier les parties (3) aux parties (4) après la mise en forme du récipient lorsque les parties (3) et (4) s'étendent perpendiculairement par rapport au fond (2).The cutout (1) comprises a central part (2) intended to form the bottom of the container to be formed, two parts (3) forming the longitudinal vertical walls and two parts (4) forming the transverse vertical walls of the container to be formed. Each part (3) further comprises two sealing tabs (5) allowing the parts (3) to be linked to the parts (4) after the container has been shaped when the parts (3) and (4) extend perpendicular to the bottom (2).

Les deux parties (4) destinées à former les parois verticales transversales du récipient portent au voisinage de leurs extrémités latérales, des montants de renforcement (6) constitués d'éléments en bois de section triangulaire. Ces renforts ou montants (6) s'étendent au-delà de l'extrémité extérieure ou supérieure de la partie (4) correspondante et sont fixés sur celle-ci par collage avant la mise en forme de la découpe lorsque les différentes parties (2, 3 et 4) de la découpe (1) s'étendent à plat dans un même plan.The two parts (4) intended to form the transverse vertical walls of the container carry, in the vicinity of their lateral ends, reinforcing uprights (6) made of wooden elements of triangular section. These reinforcements or uprights (6) extend beyond the outer or upper end of the corresponding part (4) laying and are fixed on it by gluing before the shaping of the cut when the different parts (2, 3 and 4) of the cut (1) lie flat in the same plane.

En regard de l'extrémité intérieure ou inférieure de chaque renfort (6), la partie de fond (2) de la découpe présente une partie ajourée (7) dont la section correspond sensiblement à celle des renforts (6) et qui permet d'une manière connue un empilage vertical de plusieurs récipients réalisés à partir de découpes selon.la présente invention.Opposite the inner or lower end of each reinforcement (6), the bottom part (2) of the cutout has an openwork part (7) whose section corresponds substantially to that of the reinforcements (6) and which makes it possible to in a known manner a vertical stacking of several containers made from blanks according to the present invention.

Entre les différentes parties (2, 3, 4 et 5) de la découpe (1), sont prévues d'une manière connue des amorces de pliage (8) réalisées, par exemple,par rainurage et qui permettent le pliage des parties les unes par rapport aux autres pour la mise en forme de la découpe.Between the different parts (2, 3, 4 and 5) of the cutout (1), there are provided in a known manner folding starters (8) produced, for example, by grooving and which allow the folding of the parts together compared to the others for the shaping of the cutout.

Les figures 2 à 5 montrent les phases essentielles du procédé selon l'invention pour la mise en forme de la découpe représentée à la figure 1. A la figure 2, on voit un tapis transporteur (9) horizontal portant des taquets (10) pour le positionnement et l'entrainement des renforts (6) des des positions relatives prédéterminées correspondant à leur position sur le flan de carton découpé et rainé (1). Lors de l'avance des renforts sur le tapis (9), on dépose à l'aide d'un pistolet distributeur de colle (11), une couche d'une matière adhréslve (12) sur la face supérieure de chaque renfort (6), figure 2.Figures 2 to 5 show the essential phases of the method according to the invention for shaping the cutout shown in Figure 1. In Figure 2, we see a conveyor belt (9) horizontal carrying tabs (10) for positioning and driving the reinforcements (6) of the predetermined relative positions corresponding to their position on the blank of cardboard cut and grooved (1). During the advance of the reinforcements on the mat (9), using a glue distributor gun (11), a layer of an adhesive material (12) is deposited on the upper face of each reinforcement (6 ), Figure 2.

Ensuite, on dépose le flan découpé et rainé (1) sur les renforts (6) pour le sceller sur ceux-ci grâce à la couche d'adhésif. Cette opération peut être aisément effectuée sans arrêt du transporteur à l'aide d'un distributeur de découpes d'un type connu disposé au-dessus du transporteur.Then, the cut and grooved blank (1) is deposited on the reinforcements (6) to seal it on these thanks to the layer of adhesive. This operation can easily be carried out without stopping the conveyor using a cut-out dispenser of a known type placed above the conveyor.

Lorsque la matière adhésive (12) qui est de préférence une colle déposée à chaud en fusion sur les renforts (6) a durci et assure un scellage solide du flan de carton (1) sur les renforts, on soulève l'ensemble de la découpe (1, 6) à l'aide d'un vérin (13) vers le haut de sorte que les parties (4) portant les renforts (6) se rabattent sous l'action de la gravité, vers le bas, pour faciliter la mise en forme du récipient (figure 5). Cette opération peut être effectuée sur le transporteur (9), comme représenté schématiquement en (14) à la figure 4. Dans ce cas, le transporteur est constitué de deux bandes séparées longitudinales entre lesquelles est ménagé un passage pour le vérin (13). Elle peut également être effectuée hors du transporteur (9) comme représenté schématiquement à la figure 5.When the adhesive material (12) which is preferably a hot-melt glue melted on the reinforcements (6) has hardened and ensures a solid sealing of the cardboard blank (1) on the reinforcements, the entire cutout is lifted. (1, 6) using a jack (13) upwards so that the parts (4) carrying the reinforcements (6) fold down under the action of gravity, downwards, to facilitate the shaping of the container (Figure 5). This operation can be carried out on the conveyor (9), as shown diagrammatically in (14) in FIG. 4. In this case, the conveyor consists of two separate longitudinal strips between which a passage for the jack (13) is provided. It can also be carried out outside the conveyor (9) as shown diagrammatically in FIG. 5.

Ensuite, les deux autres parties (3) sont rabattues vers le bas et les pattes (5) sont repliées sur la face extérieure des parties (4) et y sont fixées par scellage et agrafage.Then, the other two parts (3) are folded down and the tabs (5) are folded over the outer face of the parts (4) and are fixed there by sealing and stapling.

Ces phases sont connues et à la portée de l'homme de l'art et ne sont, pour cette raison, pas illustrées ou décrites ici.These phases are known and within the reach of ordinary skill in the art and are therefore not illustrated or described here.

Bien entendu, l'invention n'est pas limitée aux:<modes de réalisation décrits et représentés ici mais on peut y apporter de nombreuses modifications sans pour cela sortir du cadre de l'invention.Of course, the invention is not limited to: <embodiments described and shown here, but many modifications can be made without departing from the scope of the invention.

Par exemple, on peut remplacer le collage de la découpe par une fixation de la découpe par agrafage connue en soi.For example, the bonding of the blank can be replaced by fixing the blank by stapling known per se.
