Description
La présente invention est relative à un procédé et une machine pour le calage des objets préalablement déposés à l'intérieur d'une caisse en carton, carton ondulé ou en matière en feuilles analogue, présentant une section carrée ou rectangulaire.The present invention relates to a method and a machine for wedging objects previously deposited within a box of cardboard, corrugated cardboard or the like sheet material having a square or rectangular section.
Le domaine technique de invention est celui des machines de conditionnement, de fabrication ou de fermeture d'emballages ou de fabrication et mise en oeuvre de matériaux de calage pour de tels emballages.The technical field of invention is that of packaging machines, manufacture or closure of packaging or manufacturing and implementation of cushioning materials for such packaging.
La présente invention est plus particulièrement relative à la mise en place d'un matériau de calage à l'intérieur de caisses utilisées pour la préparation de commandes multi-articles et plus généralement de caisses dont le contenu a un volume variable d'une caisse à l'autre, lequel matériau de calage a pour fonction d'immobiliser ce contenu lors des manipulations ultérieures de la caisse, par exemple jusqu'à sa réception par le destinataire.The present invention is more particularly related to the introduction of a cushioning material inside crates used for the preparation of multi-item orders and more generally of crates whose contents have a variable volume of a cash register. the other, which blocking material has the function of immobilizing this content during subsequent manipulations of the box, for example until it is received by the recipient.
On sait que les caisses de ce type sont formées par des machines à partir d'un flan de matière en feuille comportant différents volets ou rabats assemblés par collage ou par ruban adhésif.It is known that crates of this type are formed by machines from a blank of sheet material having different flaps or flaps assembled by gluing or adhesive tape.
On connaît des caisses qui, après formage, sont composées de cinq faces, soit un fond de forme carrée ou rectangulaire et une ceinture composée de quatre faces latérales. Les caisses connues de ce type sont dites "demi-caisses américaines", "barquettes" ou "caisses cloche". Ces caisses sont, après remplissage, fermées par un couvercle. On connaît des couvercles qui possèdent quatre volets qui sont rabattus et collés sur les côtés de la caisse. On connaît également des couvercles dont les différents volets sont préalablement mis en forme; ces couvercles sont insérés sur le dessus de la caisse et solidarisés à la caisse par collage ou par un lien métallique ou plastique.Boxes are known which, after forming, are composed of five faces, a square or rectangular bottom and a belt composed of four lateral faces. Known cases of this type are called "American half-boxes", "trays" or "bell cases". These boxes are, after filling, closed by a lid. Lids are known that have four flaps that are folded and glued to the sides of the box. Lids are also known whose different shutters are previously shaped; these lids are inserted on the top of the body and secured to the body by gluing or by a metal or plastic link.
On connaît des caisses qui, après formage, sont composées de cinq faces, comme les caisses précédemment décrites, et de quatre volets supérieurs. Chacun de ces volets est relié à l'une des faces latérales de la caisse par une ligne de pliage. Les caisses connues de ce type sont dites "caisses américaines". Ces caisses sont, après remplissage, fermées par repli des quatre volets supérieurs qui sont maintenus en position par collage ou par un lien métallique ou plastique.Boxes are known which, after forming, are composed of five faces, like the boxes previously described, and four upper panels. Each of these flaps is connected to one of the lateral faces of the box by a fold line. Known cases of this type are called "American boxes". These boxes are, after filling, closed by folding the four upper flaps which are held in position by gluing or by a metal link or plastic.
Les caisses décrites ci-dessus ont pour caractéristique d'offrir un volume constant après fabrication et fermeture.The boxes described above have the characteristic of offering a constant volume after manufacture and closure.
Plusieurs moyens sont employés par les utilisateurs ou intégrés aux machines de formage et de fermeture des caisses, pour caler les différents objets dont le nombre et le volume unitaire varient d'une caisse à l'autre.Several means are used by the users or integrated in the machines forming and closing crates, to wedge different objects whose number and unit volume vary from one fund to another.
On connaît les films en plastique thermorétractable dont une ou plusieurs feuilles sont solidarisées avec le fond ou les faces latérales de la caisse pendant son formage. Après remplissage de la caisse, ces films sont rabattus sur la pile d'objets puis rétractés par passage dans un tunnel chauffant.Heat-shrinkable plastic films are known, one or more sheets of which are secured to the bottom or the lateral faces of the box during its forming. After filling the box, these films are folded on the pile of objects and then retracted by passing through a heating tunnel.
On connaît les particules en polystyrène qui sont répandues à l'intérieur de la caisse après remplissage, pour combler le volume inutilisé.Polystyrene particles are known which are spread inside the box after filling, to fill the unused volume.
On connaît les poches en plastique gonflables qui sont disposées à l'intérieur des caisses pour combler ce volume inutilisé.There are known inflatable plastic bags which are arranged inside the crates to fill this unused volume.
De tels processus de fabrication présentent de nombreux inconvénients. En effet :
- ces matériaux de calage doivent être nécessairement désolidarisés de l'emballage carton avant collecte et recyclage éventuel des déchets correspondants; cette collecte est donc une opération complexe et très onéreuse;
- les matériaux employés pour le calage sont eux-mêmes onéreux;
- leur mise en oeuvre est difficile et nécessite, soit des machines automatisées complexes, soit un grand nombre d'heures de main d'oeuvre; le coût de ces opérations est donc élevé.
- these cushioning materials must necessarily be disconnected from the cardboard packaging before collection and possible recycling of the corresponding waste; this collection is therefore a complex and very expensive operation;
- the materials used for wedging are themselves expensive;
- their implementation is difficult and requires either complex automated machines or a large number of manpower hours; the cost of these operations is therefore high.
On connaît également les copeaux, particules, boules agglomérées,... de papier, de carton ou de bois qui sont, sous diverses formes, disposés à l'intérieur des caisses pour combler le volume inutilisé.Also known chips, particles, balls agglomerated, paper, cardboard or wood which are, in various forms, arranged inside the boxes to fill the unused volume.
De tels processus de fabrication présentent également plusieurs inconvénients. En effet :
- le dosage de la distribution de ces matériaux de calage, de façon à occuper exactement le volume inutilisé, est une opération difficilement automatisable qui nécessite, soit des machines automatisées complexes, soit un grand nombre d'heures de main d'oeuvre; le coût de ces opérations est donc élevé;
- la collecte de ces matériaux après ouverture de l'emballage, nécessite de rassembler une multitude d'éléments épars et est donc une opération peu aisée à réaliser pour l'utilisateur final.
- the dosage of the distribution of these setting materials, so as to occupy exactly the unused volume, is an operation that is difficult to automate and which requires either complex automated machines or a large number of hours of labor; the cost of these operations is therefore high;
- the collection of these materials after opening the packaging, requires gather a multitude of scattered elements and is therefore a little easy operation to achieve for the end user.
Le problème posé consiste donc à procurer un moyen de calage des objets à l'intérieur de caisses utilisées pour l'expédition de colis dont le volume utile est variable, et à faire en sorte que ce moyen de calage et sa mise en oeuvre soient peu onéreux et génèrent un minimum de contraintes pour celui qui réalise l'emballage avant expédition et pour celui qui ouvre l'emballage à la réception du colis.The problem posed therefore consists in providing a means of setting objects inside crates used for the shipping of parcels whose useful volume is variable, and in ensuring that this means of setting and its implementation are not very easy. expensive and generate a minimum of constraints for the one who makes the packaging before shipping and for the one who opens the package upon receipt of the package.
Le document EP-0.251.945 décrit un procédé et un système suivant lesquels une caisse destinée à recevoir des produits expansibles après compression est pourvue en son pourtour et en partie haute d'un repli disposé en sens inverse du rebord d'un couvercle qui, après avoir été enfoncé dans la caisse, remonte sous l'effet d'expansion des produits comprimés, jusqu'à ce que son rebord replié viennent s'engager et s'immobiliser dans les replis supérieurs de la caisse. Ce procédé et ce système nécessitent pour fonctionner un complet remplissage de la caisse, de sorte qu'ils ne sont pas applicables à la fermeture de caisses incomplètement remplies et dont les contenus peuvent présenter des hauteurs et conformations variées.The document EP-0,251,945 describes a method and a system according to which a box intended to receive expandable products after compression is provided at its periphery and in the upper part of a fold disposed in the opposite direction of the rim of a lid which, after being pressed into the box, rises under the effect of expansion of compressed products, until its folded edge come to engage and stop in the upper folds of the box. This method and this system require a complete filling of the box, so that they are not applicable to the closing of incompletely filled boxes whose contents may have various heights and conformations.
Le document FR-919.469 concerne un emballage pour expédition de fleurs coupées selon lequel les fleurs sont couchées dans une caisse et recouvertes d'une feuille de papier cristal ; elles sont ensuite immobilisées dans cette caisse au moyen d'une feuille de carton disposée transversalement dans la partie médiane de celle-ci et fixée par agrafage, par l'intermédiaire de ses extrémités repliées, sur les côtés longitudinaux de la caisse. La boîte est ensuite fermée au moyen d'un couvercle classique. Il s'agit, en fait, d'un emballage spécifique aux fleurs coupées, constitué d'une boîte de carton classique, nécessitant la mise en oeuvre de moyens particulier pour l'immobilisation des fleurs à l'intérieur de la boîte.The document FR-919,469 relates to a package for shipping cut flowers according to which the flowers are lying in a box and covered with a sheet of crystal paper; they are then immobilized in this box by means of a sheet of cardboard arranged transversely in the median part thereof and fixed by stapling, by means of its folded ends, on the longitudinal sides of the box.
