Description

La présente invention a pour objet un organe de renforcement d'un outil plan utilisé dans une machine destinée notamment à l'industrie de l'emballage, plus particulièrement dans une station d'éjection de déchets d'une presse à platine pour la fabrication d'ébauches de boîtes à partir de feuilles de carton, de papier ou de matières synthétiques par exemple.The present invention relates to a reinforcing member of a flat tool used in a machine intended in particular for the packaging industry, more particularly in a waste ejection station of a platen press for the manufacture of blanks of boxes from cardboard sheets, paper or synthetic materials for example.

Généralement, une presse à platine comprend plusieurs stations placées les unes à la suite des autres, dont notamment un margeur permettant d'alimenter la machine en feuilles de carton à partir d'une pile, une station de découpage découpant les feuilles une à une suivant une forme donnée pour produire des découpes de boîtes, une station d'éjection retirant les déchets indésirables résultant du découpage, et enfin une station de réception en piles des découpes ainsi façonnées.Generally, a platen press comprises several stations placed one after another, including a feeder for feeding the machine sheets of cardboard from a stack, a cutting station cutting the sheets one by one following a given form for producing box blanks, an ejection station removing unwanted waste resulting from cutting, and finally a stacks receiving station shaped blanks.

Les feuilles sont chacune appréhendées en leur bord frontal par une barre de pinces en déplacement sur un train de chaînes qui les emmène tour à tour dans les différentes stations. Les feuilles, appelées aussi éléments en plaque, travaillées par de telles machines comprennent généralement chacune une pluralité de poses ou découpes qui représentent les formes et les surfaces développées des emballages fabriqués.The leaves are each apprehended at their front edge by a clip bar moving on a train of chains which takes them in turn in different stations. The sheets, also called plate elements, worked by such machines generally each comprise a plurality of poses or cuts which represent the shapes and developed surfaces of the packages produced.

Les contours de ces poses sont découpés par des filets coupeurs dans la presse à platine, alors que les lignes de pliage de ces poses sont marquées par des filets refouleur au cours de la même opération. Pour éviter que la feuille ne se disloque une fois découpée, les filets coupeurs auront été préalablement entaillés au droit de chaque jointure de poses. De ce fait, toutes les poses restent fragilement maintenues entre elles par des ponts de matière, appelés points d'attache, épargnés du découpage par les entailles pratiquées dans les filets coupeurs.The contours of these poses are cut by cutting nets in the platen press, while the fold lines of these poses are marked by threads in the same operation. To prevent the sheet from being broken once cut, the cutting nets have been cut beforehand at the right of each joint of poses. As a result, all the poses remain fragilely held together by material bridges, called attachment points, spared from cutting by the cuts made in the cutting nets.

Bien que l'arrangement des poses sur la feuille soit effectué de la façon la plus judicieuse possible, il n'est généralement pas possible d'éviter de produire des déchets résultant du découpage. Ces déchets sont constitués par le pourtour de la feuille et par les parties interstitielles qui séparent les poses entre elles. Ce sont ces surfaces qui constituent les déchets indésirables qu'il convient de retirer de la feuille dans la station d'éjection des déchets.Although the arrangement of the poses on the sheet is done as judiciously as possible, it is generally not possible to avoid producing waste resulting from cutting. This waste is formed by the perimeter of the leaf and by the interstitial parts which separate the poses between them. It is these surfaces that constitute the undesirable waste that should be removed from the sheet in the waste ejection station.

Une telle station comprend généralement un outil supérieur mobile dans le plan vertical et doté d'éjecteurs, une planche d'éjection ajourée sur laquelle les feuilles viennent successivement s'arrêter pour être débarrassées de leurs déchets, et généralement un outil inférieur collaborant avec l'outil supérieur pour retirer les déchets de la feuille. D'un format semblable à celui de la feuille, l'outil supérieur se présente sous la forme d'une planche perforée ou d'un cadre muni de plusieurs barres sur lesquelles sont montées des aiguilles d'éjection qui détachent les déchets de la feuille en les poussant vers le bas au travers des ajours de la planche d'éjection. Parfois, l'outil supérieur comprend également des presseurs, constitués par exemple par de petits cubes de mousse, qui ont pour simple effet de maintenir les poses de la feuille contre la face supérieure de la planche d'éjection. L'outil inférieur comprend des aiguilles d'éjection télescopiques disposées en regard de celles de l'outil supérieur. Cette disposition permet précisément de pincer tous les déchets et de les retirer de la feuille en une seule opération au travers de la planche d'éjection. Une telle station d'éjection est illustrée et décrite plus en détail dans le brevet CH689974.Such a station generally comprises an upper tool movable in the vertical plane and provided with ejectors, a perforated ejection board on which the sheets are successively stop to be cleared of their waste, and generally a lower tool collaborating with the upper tool for removing waste from the sheet. In a format similar to that of the sheet, the upper tool is in the form of a perforated board or a frame provided with several bars on which are mounted ejection needles which detach the waste from the sheet pushing them down through the openings of the ejection board. Sometimes, the upper tool also includes pressers, constituted for example by small cubes of foam, which have the simple effect of maintaining the poses of the sheet against the upper face of the ejection board. The lower tool includes telescopic ejection needles arranged opposite those of the upper tool. This arrangement makes it possible to pinch all the waste and remove it from the sheet in a single operation through the ejection board. Such an ejection station is illustrated and described in more detail in patent CH689974.

Il se peut parfois que l'outil inférieur ne soit pas utilisé; les déchets sont alors éjectés de la feuille par la seule action des éjecteurs de l'outil supérieur qui les poussent vers le bas. Dans ce cas, l'éjection est dite "dynamique". A haute vitesse, la planche d'éjection est par contre soumise à de fortes pressions verticales du fait que les déchets, n'étant plus pincés pour être retirés, doivent reposer partiellement sur les bords de l'ouverture prévue pour leur éjection afin de les faire avant tout fléchir vers le bas pour en casser simultanément tous les points d'attache. Sans un tel positionnement de la feuille, certains points d'attache risquent de ne pas être brisés, laissant pendre alors les déchets au travers des ajours de la planche et provoquer un inévitable bourrage lors de l'évacuation de la feuille hors de la station d'éjection. La solution visant à pincer les déchets entre un outil supérieur et un outil inférieur permet donc de garantir, à très haute vitesse, une parfaite élimination de tous les déchets de la feuille sans aucun bourrage.Sometimes the lower tool may not be used; the waste is then ejected from the sheet by the action of the ejectors of the upper tool which push them down. In this case, the ejection is called "dynamic". At high speed, the ejection board is subjected to high vertical pressures because the waste, being no longer pinched to be removed, must rest partially on the edges of the opening provided for their ejection in order to Above all, bend downwards to break all the points of attachment at the same time. Without such positioning of the sheet, some attachment points may not be broken, leaving the waste then hanging through the openings of the board and cause an inevitable jamming during the evacuation of the sheet out of the station. 'ejection. The solution to pinch the waste between an upper tool and a lower tool thus ensures, at very high speed, a perfect elimination of all waste from the sheet without any jam.

C'est en particulier sur l'outil plan d'une telle station, outil appelé aussi planche d'éjection, que l'objet de la présente invention trouve principalement son utilisation. Les outils supérieur et inférieur, ainsi que la planche d'éjection, sont généralement chacun disposés et fixés sur un cadre porteur pouvant être facilement extrait de la station d'éjection dans le plan horizontal à la manière d'un tiroir. Destinée à ne supporter que les poses de la feuille tout en permettant le retrait des déchets, la planche d'éjection ne présente que rarement des bords rectilignes mais possède des bords irréguliers qui reproduisent les contours des poses situées en périphérie de la feuille. De ce fait, la planche d'éjection ne peut pas être directement fixée dans son cadre porteur par ses bords, mais nécessite d'être montée sur des barres longitudinales adaptées pour pouvoir être placées et maintenues dans le cadre porteur par leurs extrémités. Ces barres portantes ont généralement une section rectangulaire, dont les plus longs côtés sont orientés verticalement pour pouvoir bénéficier d'une plus grande rigidité à la flexion. Elles sont fixées contre la face inférieure de la planche d'éjection par des équerres vissées, d'une part contre les flancs de ces barres, et d'autre part dans la planche en question. Le brevet CH575294 illustre bien ce mode d'agencement dans ses figures 2 et 3.It is in particular on the plan tool of such a station, a tool also called ejection board, that the object of the present invention finds its use mainly. The upper and lower tools, as well as the ejection board, are generally each arranged and fixed on a support frame which can be easily extracted from the ejection station in the horizontal plane in the manner of a drawer. Intended to support only the poses of the sheet while allowing the removal of waste, the ejection board only rarely has straight edges but has irregular edges that reproduce the contours of the poses located on the periphery of the sheet. Therefore, the ejection board can not be directly fixed in its carrier frame by its edges, but needs to be mounted on longitudinal bars adapted to be placed and held in the carrier frame by their ends. These bearing bars generally have a rectangular section, the longer sides are oriented vertically to benefit from greater flexural rigidity. They are fixed against the underside of the ejection board by screwed brackets on the one hand against the flanks of these bars, and on the other hand in the board in question. Patent CH575294 illustrates this mode of arrangement in FIGS. 2 and 3.

Ce mode de réalisation présente plusieurs inconvénients à savoir que pour leur fixation, ces barres requièrent une multitude de petites pièces détachées (équerres et visserie) qui nécessitent des travaux de perçage, d'ajustage et d'assemblage relativement longs. De plus, ce mode de réalisation occupe à la surface de la planche d'éjection une certaine place non négligeable nécessaire aux équerres de fixation. Par ailleurs, compte tenu du nombre important de pièces de visserie nécessaires par planche d'éjection, ces pièces sont généralement récupérées tout comme les équerres de fixation. Or, du fait que chaque planche d'éjection est propre à un travail spécifique, la récupération de telles pièces nécessite un travail de démontage qui ne contribue qu'à renchérir le coût de réalisation d'une tâche donnée. Pour réduire les coûts de fabrication et de préparation d'une planche d'éjection, on a déjà pensé à remplacer les barres de renforcement généralement métalliques par des barres d'un autre matériau meilleur marché et pouvant être collé comme le bois. Or, étant moins solide que le métal, ce matériau nécessite en contre partie un dimensionnement plus important de l'épaisseur des barres de renforcement. Ce surdimensionnement a l'inconvénient d'occuper davantage de place à la surface de la planche d'éjection et par conséquent il devient aussi plus difficile de disposer de telles barres sur la planche d'éjection tout en évitant tous les ajours destinés à l'éjection des déchets pour ne pas les obstruer. Les extrémités des barres portantes ont généralement une forme plus effilée, usinée de façon à ce qu'elles puissent venir en prise avec le système de fixation prévu sur le cadre porteur de la station pour lequel il est destiné. Or, lorsque ces barres sont en bois, le profil effilé de leurs extrémités fragilise ces dernières qui deviennent délicates et nécessitent une attention toute particulière lors de leur manutention. Enfin, en raison de leur usure rapide, des tests en atelier ont également montrés que de telles planches d'éjection avaient assez vite tendance à être sujettes à des vibrations progressives en cours d'utilisation prolongée.This embodiment has several disadvantages that for their fixing, these bars require a multitude of small parts (brackets and screws) that require drilling, fitting and assembly relatively long. In addition, this embodiment occupies on the surface of the ejection board a certain non-negligible place necessary for fastening brackets. In addition, given the large number of hardware required by ejection board, these parts are generally recovered as the brackets. However, because each ejection board is specific to a specific job, the recovery of such parts requires disassembly work that only increases the cost of performing a given task. To reduce the costs of manufacturing and preparation of an ejection board, it has already been thought to replace the generally metallic reinforcement bars with bars of another cheaper material that can be glued like wood. However, being less solid than the metal, this material requires in part a larger dimensioning of the thickness of the reinforcement bars. This oversizing has the disadvantage of occupying more space on the surface of the ejection board and therefore it also becomes more difficult to have such bars on the ejection board while avoiding all openings for the ejection of waste so as not to obstruct it. The ends of the load-bearing bars generally have a tapered shape, machined so that they can come into engagement with the fastening system provided on the carrier frame of the station for which it is intended. Gold, when these bars are wood, the tapered profile of their ends weakens the latter which become delicate and require special attention when handling. Finally, because of their rapid wear, in-shop tests have also shown that such ejection boards quickly tend to be prone to progressive vibrations during prolonged use.

Pour pallier ces inconvénients, un autre organe connu est quant à lui divulgué dans le document EP 1'348'524 et a trait à une barre de renforcement qui comporte sur son chant supérieur une pluralité de têtes de fixation pouvant s'insérer dans des ouvertures ménagées dans la planche d'éjection. L'assemblage d'une telle barre sur la planche d'éjection s'effectue en exerçant une pression sur cette barre jusqu'à ce que les têtes de fixation s'insèrent correctement dans les ouvertures correspondantes. Les têtes de fixation étant chacune dotées d'une paire de griffes dont la forme rappelle celle d'un hameçon, ce mode d'assemblage permet de réaliser une fixation à demeure sans l'adjonction d'aucune pièce additionnelle rapportée contre les flancs de la barre.To overcome these disadvantages, another known member is in turn disclosed in EP 1'348'524 and relates to a reinforcing bar which has on its upper edge a plurality of fixing heads that can be inserted into openings arranged in the ejection board. The assembly of such a bar on the ejection board is effected by exerting pressure on the bar until the fixing heads fit correctly into the corresponding openings. The fixing heads being each provided with a pair of claws whose shape reminiscent of a hook, this method of assembly allows for permanent fixing without the addition of any additional piece attached to the flanks of the closed off.

Cependant, l'inconvénient de cet organe réside dans le fait qu'une fois insérée dans la planche d'éjection, la barre de renforcement ne peut plus est retirée; ce mode de fixation étant permanent, définitif et à usage unique. Chaque nouveau travail de façonnage d'une feuille dans une presse à platine nécessite, pour les différentes stations, des outils spécifiques qui sont directement fonction de la forme des poses à réaliser. Or, lors de petites séries, le coût de fabrication des emballages s'en trouve renchérit par la courte durée d'utilisation des outils plans spécifiques qui ne peuvent être échangés même pour des séries que légèrement différentes. A titre de comparaison, la valeur d'un jeu de barres de renforcement pour un outil plan représente environ les 25% du prix de vente de la planche d'éjection. Proportionnellement, on constate donc que le coût de telles barres de renforcement n'est pas négligeable par rapport au coût de l'outil plan. De ce fait, on comprend qu'il serait souhaitable de pouvoir récupérer ces barres afin de les réutiliser pour d'autres outils plans.However, the disadvantage of this member lies in the fact that once inserted into the ejection board, the reinforcement bar can no longer be removed; this method of fixing being permanent, definitive and disposable. Each new work of shaping a sheet in a platen press requires, for the different stations, specific tools that are directly related to the shape of the poses to be made. However, in small series, the cost of manufacturing packaging is increased by the short period of use of specific plan tools that can not be exchanged even for series that slightly different. For comparison, the value of a reinforcing busbar for a plane tool represents approximately 25% of the selling price of the ejection board. Proportionally, we therefore see that the cost of such reinforcing bars is not negligible compared to the cost of the plan tool. As a result, it is understood that it would be desirable to be able to recover these bars in order to reuse them for other flat tools.

Un autre inconvénient de cet organe provient du fait qu'il est issu d'une fabrication uniforme et standardisée ne permettant aucune adaptation possible en dehors du gabarit initial pour lequel il a été conçu. De ce fait, il devient impossible de vouloir employer un tel même organe pour des outils plans ayant des dimensions différentes de celles qui étaient prévues à l'origine. Or, il n'est pas rare de trouver des parcs de machines composés de plusieurs presses issues de fabricants distincts, utilisant des outils spécifique non normalisés.Another disadvantage of this body comes from the fact that it comes from a uniform and standardized manufacturing allowing no possible adaptation outside the original template for which it was designed. As a result, it becomes impossible to use such an organ for flat tools with dimensions different from those originally planned. But it is not uncommon to find machine parks composed of several presses from different manufacturers, using specific non-standardized tools.

Un autre inconvénient de cet organe réside dans le fait qu'il est nécessaire de recourir à un outil supplémentaire, tel qu'un marteau ou un maillet, pour pouvoir correctement enfoncer les barres de renforcement dans l'outil plan. En raison de la forme des griffes, qui comprennent des parties saillantes s'insérant dans les flancs des ouvertures de la planche d'éjection, il est en effet nécessaire d'appliquer une certaine force pour réussir à faire plaquer correctement le chant supérieur de la barre contre la surface de l'outil plan. Cette force est d'autant plus grande que le nombre de tête de fixation est élevé et dépend directement de la tolérance d'usinage entre la largeur hors tout des griffes et celle de l'ouverture dans laquelle elles doivent venir s'y insérer. De plus, en raison de l'effet tranchant que provoque la faible surface du chant de ces organes de renforcement, il est difficilement supportable pour un monteur de mettre en place à main nues toute une série de barres sur une même planche d'éjection. Or, le recours a un outil de frappe engendre des nuisances évidentes que l'on recherche plutôt à réduire dans un environnement déjà passablement bruyant au vu du fonctionnement constant des machines environnantes.Another disadvantage of this member lies in the fact that it is necessary to use an additional tool, such as a hammer or a mallet, to be able to properly push the reinforcing bars in the plane tool. Because of the shape of the claws, which include protruding parts fitting into the flanks of the openings of the ejection board, it is indeed necessary to apply a certain force to succeed in correctly plating the upper edge of the bar against the surface of the plane tool. This force is even greater than the number of fixing head is high and depends directly on the machining tolerance between the overall width of the claws and that of the opening in which they must be inserted. In addition, because of the sharp effect that causes the small surface of the edge of these reinforcing members, it is difficult for a fitter to set up with bare hands a series of bars on the same ejection board. However, the use of a striking tool generates obvious nuisances that are sought instead to reduce in an already fairly noisy environment given the constant operation of surrounding machines.

Le but de la présente invention est de fournir un organe qui puisse renforcer un outil plan dans une machine destinée à la fabrication d'emballages, plus particulièrement dans un station d'éjection d'une presse à platine, en s'affranchissant de tous les inconvénients précités. Cet organe doit également pouvoir constituer un moyen de support et de fixation de l'outil plan. Dans ce but, l'objet de la présente invention doit pouvoir être récupérable en vue d'une utilisation ultérieure sur d'autres outils plans, et à ces fins cet organe doit pouvoir être facilement et rapidement monté et démonté de chaque outil plan. La fixation sur de tels outils ne doit dépendre d'aucune pièce additionnelle et ne doit pas non plus recourir à une quelconque substance adhésive ni à tout autre élément susceptible de procurer le même effet. Un autre but visé par l'objet de la présente invention est de fournir un organe qui puisse avoir une longueur variable s'adaptant à tout outil de taille usuelle. Enfin, l'organe en question doit pouvoir bénéficier d'un coût de fabrication modeste par rapport au prix de revient de l'outil plan pour lequel il est utilisé et par rapport à sa durée de vie, à savoir une utilisation illimitée jusqu'à la rupture d'un élément qui le compose.The object of the present invention is to provide a member which can reinforce a flat tool in a machine intended for the manufacture of packaging, more particularly in an ejection station of a platen press, by dispensing with all aforementioned drawbacks. This body must also be able to constitute a means of support and fixation of the plan tool. For this purpose, the object of the present invention must be retrievable for later use on other flat tools, and for these purposes it must be easily and quickly mounted and removed from each planar tool. Attachment to such tools must not depend on any additional parts and must not use any adhesive substance or any other element capable of producing the same effect. Another aim of the object of the present invention is to provide a member that can have a variable length adapting to any tool of conventional size. Finally, the body in question must be able to benefit from a modest manufacturing cost compared to the cost price of the tool plane for which it is used and in relation to its life, namely unlimited use until the breaking of an element that composes it.

Ces buts sont atteints grâce à la présente invention qui a pour objet un organe de renforcement d'un outil plan, conforme à ce qu'énonce la revendication 1.These objects are achieved by the present invention which relates to a reinforcing member of a planar tool, according to the statement of claim 1.

L'invention sera mieux comprise à l'étude d'un mode de réalisation pris à titre nullement limitatif, illustré par les figures annexées dans lesquelles:

  • Les figure 1 a et 1b sont respectivement des vues en élévation de la partie avant et centrale, et de la partie arrière de l'objet de l'invention illustré dans une position dite ouverte sur un outil plan représenté en coupe.
  • La figure 2 est une vue en élévation de la partie avant de l'objet de l'invention illustré dans une position dite fermée.
  • La figure 3 est une vue de gauche de la figure 2.
  • La figure 4 est une vue de dessus de la figure 2.
The invention will be better understood from the study of an embodiment taken in no way limiting, illustrated by the appended figures in which:
  • Figures 1a and 1b are respectively elevational views of the front and central part, and the rear part of the object of the invention shown in a so-called open position on a flat tool shown in section.
  • Figure 2 is an elevational view of the front portion of the object of the invention shown in a so-called closed position.
  • Figure 3 is a left view of Figure 2.
  • FIG. 4 is a view from above of FIG. 2.

Les figures 1 a et 1b illustrent, dans des vues en élévation, l'organe 1 de la présente invention dans une position dite ouverte sur un outil plan 2 représenté en coupe. Etant de forme longiligne dont la géométrie rappelle celle d'une barre, la représentation de l'organe 1 est illustrée en deux portions, respectivement dans les figures 1 a et 1b. La figure 1a montre la partie avant 10 de l'organe 1 ainsi que sa partie centrale 30 en coupe partielle, alors que la figure 1b montre la partie arrière 40 destinée à venir s'emboîter dans la partie centrale 30. La forme générale de l'organe 1 est préférentiellement celle d'une barre rectiligne au profil étroit, disposée sur son chant supérieur 3 contre la surface inférieure 4 de l'outil plan 2. Ce dernier pouvant être typiquement une planche d'éjection d'une presse à platine non illustrée.Figures 1a and 1b illustrate, in elevational views, the member 1 of the present invention in a so-called open position on a flat tool 2 shown in section. Being of elongate shape whose geometry remembers that of a bar, the representation of the member 1 is illustrated in two portions, respectively in Figures 1a and 1b. Figure 1a shows the front portion 10 of the member 1 as well as its central portion 30 in partial section, while Figure 1b shows the rear portion 40 intended to fit into the central portion 30. The general shape of the 1 member is preferably that of a straight bar narrow profile, disposed on its upper edge 3 against the lower surface 4 of the plane tool 2. The latter can be typically an ejection plate of a non platinum press illustrated.

La partie avant 10 comprend notamment un corps 11 doté d'un mécanisme 20 qui permet de fixer l'organe 1 sur l'outil plan 2 en passant d'une position dite ouverte à une position dite fermée, et inversement permet de le retirer pour le séparer de l'outil plan 2.The front part 10 comprises in particular a body 11 provided with a mechanism 20 which makes it possible to fix the member 1 on the flat tool 2 by passing from a so-called open position to a so-called closed position, and conversely allows it to be removed for separate it from the plane tool 2.

La fixation de l'organe 1 se fait au moyen d'au moins un ergot fixe 12 et d'au moins un ergot mobile 13, tous solidaires de l'organe 1 et destinés chacun à venir en prise avec un flanc 5 d'une ouverture 6 ménagée à cet effet dans l'outil plan 2. Chacun de ces ergots est doté d'une extrémité tranchante ou pointue pouvant se planter facilement dans du bois par exemple. Dans le mode de réalisation préféré, l'ergot fixe 12 est tourné vers l'arrière et est constitué d'une excroissance du corps 11 située à l'extrémité arrière de ce dernier, contre le chant supérieur 3. L'ergot mobile 13 est quant à lui tourné vers l'avant de sorte qu'il pointe dans la direction opposée à celle de l'ergot fixe 12. Par ailleurs, l'ergot mobile 13 peut se mouvoir dans le sens longitudinal et constitue la partie supérieure d'un étrier 14 monté en basculement autour d'un axe 15 traversant le corps 11 de l'organe 1, tel qu'illustré notamment dans la figure 3.Fixing the member 1 is done by means of at least one fixed pin 12 and at least one movable pin 13, all integral with the member 1 and each intended to engage with a flank 5 of a opening 6 provided for this purpose in the plane tool 2. Each of these pins has a sharp or pointed end that can be plant easily in wood for example. In the preferred embodiment, the fixed pin 12 is turned towards the rear and consists of an outgrowth of the body 11 located at the rear end of the latter, against the upper edge 3. The movable pin 13 is as for him turned towards the front so that it points in the opposite direction to that of the fixed pin 12. Moreover, the movable pin 13 can move in the longitudinal direction and constitutes the upper part of a yoke 14 mounted to tilt about an axis 15 passing through the body 11 of the member 1, as illustrated in particular in Figure 3.

Le mouvement longitudinal de l'ergot mobile 13 est obtenu par l'action du mécanisme 20 qui, en position ouverte ramène l'étrier 14 dans une orientation préférentiellement verticale telle qu'illustrée dans la figure 1 a, et en position fermée, comme illustré dans la figure 2, le force à basculer vers l'avant autour de son axe de rotation 15 de sorte que l'ergot mobile 13 puisse venir s'agripper à l'outil plan 2, en s'insérant dans le flanc 5 de l'ouverture 6 correspondante. A cette fin, le mécanisme 20 de fermeture et d'ouverture comprend une poignée coudée 21, faisant office de levier, reliée en l'une de ses extrémités à une tige 23 par une première articulation 22 et relié en son talon à l'extrémité d'une barrette 24 par une seconde articulation 25. Comme mieux illustré dans la figure 1 a, cette barrette 24 fait également office de levier et prend appui en son extrémité opposée au fond d'une lumière 16 ménagée dans le corps 11 de l'organe 1. La tige 23 traverse l'étrier 14 et coulisse longitudinalement dans une embrasure 17 pratiquée à cet effet dans le corps 11 de l'organe 1. Cette tige 23 comprend, entre la première articulation 22 et l'étrier 14, une portée autour de laquelle prend place un moyen élastique 27, illustré dans les figures 1 a, 2 et 4 par un ressort de compression. Ce moyen élastique, ou ressort de compression, s'appuie à l'arrière contre un épaulement 28 de la tige 23, et à l'avant contre l'étrier 14 en poussant ce dernier jusqu'à venir en butée contre une goupille d'arrêt 29 fixée transversalement au travers de la tige 23. L'ergot mobile 13 est donc poussé à la fois par l'action de la poignée coudée 21, lorsque celle-ci est fermée, et par l'action du moyen élastique 27.The longitudinal movement of the movable pin 13 is obtained by the action of the mechanism 20 which, in the open position, returns the stirrup 14 in a preferentially vertical orientation as illustrated in FIG. 1a, and in the closed position, as illustrated. in FIG. 2, the force to be tilted forwards about its axis of rotation 15 so that the mobile pin 13 can come to grip the plane tool 2, by fitting into the sidewall 5 of the corresponding opening 6. To this end, the closing and opening mechanism 20 comprises a bent handle 21, acting as a lever, connected at one of its ends to a rod 23 by a first hinge 22 and connected at its end to the end. a bar 24 by a second articulation 25. As best illustrated in Figure 1a, this bar 24 also acts as a lever and bears at its opposite end at the bottom of a slot 16 formed in the body 11 of the member 1. The rod 23 passes through the stirrup 14 and slides longitudinally in an embrasure 17 formed for this purpose in the body 11 of the member 1. This rod 23 comprises, between the first articulation 22 and the stirrup 14, a scope around which takes place an elastic means 27, illustrated in Figures 1a, 2 and 4 by a compression spring. This elastic means, or compression spring, is supported at the rear against a shoulder 28 of the rod 23, and at the front against the stirrup 14 by pushing the latter until it abuts against a pin of stop 29 fixed transversely through the rod 23. The movable pin 13 is pushed both by the action of the bent handle 21, when it is closed, and by the action of the elastic means 27.

Tel qu'illustré notamment dans la figure 4, afin d'améliorer et de garantir une certaine stabilité de l'organe 1 placé en position debout sur son chant supérieur 3, de préférence au moins une ailette 18 s'y trouve rapportée dans le but de constituer une petite surface d'appui supplémentaire s'adossant contre la surface inférieure 4 de l'outil plan 2.As illustrated in particular in Figure 4, in order to improve and ensure a certain stability of the member 1 placed in a standing position on its upper edge 3, preferably at least one fin 18 is reported therein for the purpose to constitute a small additional support surface leaning against the lower surface 4 of the planar tool 2.

De façon à ce que l'organe 1 puisse être appréhendé par le dispositif de repérage et de serrage, non illustré mais prévu dans la presse à platine pour maintenir correctement l'outil plan 2 en machine, au moins une extrémité 19 de cet organe 1 est profilée en conséquence.So that the member 1 can be apprehended by the tracking and clamping device, not shown but provided in the platen press to properly maintain the plane tool 2 in the machine, at least one end 19 of this member 1 is profiled accordingly.

La figure 1b illustre la partie arrière 40 de l'organe 1 de la présente invention. Cette partie arrière, détachable du reste de l'organe 1 sans que cela en soit une nécessité, est déplaçable dans le sens longitudinal par rapport à la partie avant 10, préférentiellement par coulissement. A cette fin, elle se compose notamment d'une portion coulissante 41 et d'une queue 42. La portion coulissante 41 coulisse le long de la partie centrale 30 de l'organe 1. Pour ce faire, et selon le mode de réalisation préféré, la partie centrale 30 est une partie tubulaire dont les dimensions intérieures sont légèrement supérieures aux dimensions extérieures de la portion coulissante 41. Ainsi, par coulissement de ces deux parties l'une par rapport à l'autre, la longueur de l'organe 1 peut varier au gré des besoins de l'utilisateur dans une plage correspondant à la longueur de la course dudit coulissement.Figure 1b illustrates the rear portion 40 of the member 1 of the present invention. This rear portion, detachable from the rest of the member 1 without being a necessity, is movable in the longitudinal direction relative to the front portion 10, preferably by sliding. To this end, it consists in particular of a sliding portion 41 and a tail 42. The sliding portion 41 slides along the central portion 30 of the member 1. To do this, and according to the preferred embodiment , the central portion 30 is a tubular portion whose inner dimensions are slightly greater than the outer dimensions of the sliding portion 41. Thus, by sliding these two parts relative to each other, the length of the member 1 may vary according to the needs of the user in a range corresponding to the length of the race of said sliding.

La queue 42 est dotée d'un ergot 43 tourné vers l'avant et de forme semblable ou identique à celle de l'ergot fixe 12 décrit précédemment. L'ergot 43 est de préférence fixe et sa fonction est également identique à celle de l'ergot fixe 12. Avantageusement, la queue est aussi dotée d'une ailette 18 de stabilisation de l'organe 1. Dans le mode de réalisation préféré, tel qu'illustré dans la figure 1b, cette queue est également dotée d'un mécanisme de fixation 20 identique à celui décrit précédemment dans la partie avant 10.The tail 42 is provided with a lug 43 facing forward and of similar or identical shape to that of the fixed lug 12 described above. The lug 43 is preferably fixed and its function is also identical to that of the fixed lug 12. Advantageously, the tail is also provided with a fin 18 for stabilizing the member 1. In the preferred embodiment, as illustrated in Figure 1b, this tail is also provided with a fastening mechanism 20 identical to that previously described in the front portion 10.

La partie arrière 40 de l'organe de la présente invention comprend un butoir 45 contre lequel peut venir s'appuyer un organe de serrage, propre à la machine d'emballage, poussant la partie arrière 40 dans le sens longitudinal. Pour ce faire, une barre transversale de cette machine vient glisser sur un plat 44 agencé à l'extrémité de la queue 42, sur le chant inférieur 7 de l'organe 1. Cette barre, non illustrée car faisant partie d'un dispositif de fixation extérieur à la présente invention, constitue l'organe de serrage qui permet de maintenir l'outil plan 2 en machine. Venant en contact contre le butoir 45 agencé sur ce chant 7 à l'avant du plat 44, cette barre transversale permettra donc de pousser la queue 42 de l'organe 1 vers l'avant, de sorte que l'ergot 43 se plante dans le flanc 5 de l'ouverture 6 correspondante et entraîne ainsi tout l'outil plan 2 dans la même direction jusqu'à ce qu'il puisse être appréhendé en machine par l'extrémité 19.The rear portion 40 of the body of the present invention comprises a stopper 45 against which can abut a clamping member, specific to the packaging machine, pushing the rear portion 40 in the longitudinal direction. To do this, a transverse bar of this machine is slid on a plate 44 arranged at the end of the tail 42, on the lower edge 7 of the member 1. This bar, not shown because part of a device of external attachment to the present invention, constitutes the clamping member that keeps the plane tool 2 in the machine. Coming in contact against the stopper 45 arranged on this edge 7 at the front of the plate 44, this transverse bar will therefore push the tail 42 of the member 1 forward, so that the pin 43 is set in the flank 5 of the corresponding opening 6 and thus drives the entire plane tool 2 in the same direction until it can be grasped in the machine by the end 19.

L'usage de l'organe 1 de la présente invention a l'avantage d'être simple, rapide et fiable. Pour mettre en place et fixer cet organe, il suffit d'insérer les ergots 12, 13 de la partie avant 10 dans les ouvertures 6 correspondantes de l'outil plan 2, d'ajuster la longueur de l'organe 1 en faisant coulisser la partie arrière 40 le long de la partie centrale 30 jusqu'à ce que l'ergot 43 de la queue 42 se glisse également dans une ouverture 6, de plaquer le chant supérieur 3 de l'organe 1 contre la surface inférieure 4 de l'outil plan, et d'abaisser la poignée coudée 21 afin de fermer le mécanisme 20 de fixation. La suite inverse de ces opérations permet de retirer tout aussi facilement l'organe de son outil plan. A ce propos, on notera que la mise en place et le retrait de l'organe 1 ne nécessite aucun outil additionnel, ni aucune autre pièce mécanique.The use of the organ 1 of the present invention has the advantage of being simple, fast and reliable. To set up and fix this member, simply insert the lugs 12, 13 of the front portion 10 into the corresponding openings 6 of the flat tool 2, adjust the length of the member 1 by sliding the rear portion 40 along the central portion 30 until the lug 43 of the tail 42 also slides in an opening 6, to press the upper edge 3 of the member 1 against the lower surface 4 of the plane tool, and lower the bent handle 21 to close the fastening mechanism 20. The reverse sequence of these operations makes it possible to remove the organ as easily from its planar tool. In this regard, it will be noted that the introduction and removal of the member 1 does not require any additional tool, nor any other mechanical part.

En raison de la simplicité de son fonctionnement et de son usage, la construction de cet organe peut être grossière et ne nécessite pas d'esthétique particulière. Ainsi, les articulations 22, 25, l'axe 15 et la goupille d'arrêt 29 peuvent par exemple être réalisés au moyen de simples goupilles élastiques. Le découpage des formes des parties avant 10 et arrière 40 peut par exemple être avantageusement usiné au laser, tout comme la lumière 16 et l'embrasure 17 notamment. La forme tubulaire de la partie centrale 30 peut être obtenue par pliage et soudage d'une plaque prévue à cet effet. L'assemblage des parties avant et centrale, tout comme l'assemblage des ailettes 18, peut également être réalisé simplement par soudage. De ce fait, on remarquera que le coût de réalisation d'un tel organe de renforcement peut être réduit à son minimum sans porter préjudice à la solidité qu'il requiert.Because of the simplicity of its operation and its use, the construction of this organ can be rough and does not require any particular aesthetic. Thus, the joints 22, 25, the axis 15 and the locking pin 29 may for example be made by means of simple elastic pins. For example, the cutting of the shapes of the front and rear portions 40 may advantageously be laser-machined, as may the light 16 and the embrasure 17 in particular. The tubular shape of the central portion 30 can be obtained by folding and welding a plate provided for this purpose. The assembly of the front and central parts, as the assembly of the fins 18, can also be achieved simply by welding. Therefore, it will be noted that the cost of producing such a reinforcing member can be reduced to a minimum without detracting from the strength it requires.

On relèvera que les ouvertures 6 sont préférentiellement de forme carrée ou rectangulaire et que leurs flancs sont avantageusement verticaux mais pourraient être légèrement inclinés ou présenter un profil particulier. L'usinage des ouvertures 6 peut être effectué très facilement au moyen d'un laser, spécialement lorsque les outils plans sont réalisés en bois comme c'est généralement le cas. Ce mode d'usinage permet en effet d'obtenir une coupe nette et précise tout en respectant des tolérances amplement suffisantes pour une telle application. De plus, grâce à l'action du moyen élastique 27 du mécanisme de fixation, l'organe 1 est assurément fixé sans jeu dans l'outil plan 2. Avantageusement, les ouvertures 6 ne requièrent donc nullement des tolérances serrées, ce qui contribue avantageusement à réduire les coûts de fabrication.It will be noted that the openings 6 are preferably of square or rectangular shape and that their flanks are preferably vertical but could be slightly inclined or have a particular profile. The machining of the openings 6 can be performed very easily by means of a laser, especially when the flat tools are made of wood as is generally the case. This machining mode makes it possible to obtain a clean and precise cut while respecting tolerances sufficient for such an application. In addition, thanks to the action of the elastic means 27 of the fastening mechanism, the member 1 is certainly fixed without play in the plane tool 2. Advantageously, the openings 6 therefore do not require close tolerances, which advantageously contributes to reduce manufacturing costs.

On remarquera que le serrage de l'organe 1 est obtenu par pression des ergots arrière 12 et avant 13 dans les ouvertures 6 selon des forces opposées orientées vers l'extérieur de l'outil plan 2. Cependant, on relèvera que le même effet de serrage pourrait être obtenu par des forces opposées orientées vers l'intérieur de l'outil 2.It will be noted that the tightening of the member 1 is obtained by pressing the rear lugs 12 and before 13 into the openings 6 in opposite forces directed towards the outside of the plane tool 2. However, it will be noted that the same effect of tightening could be achieved by opposing forces directed towards the inside of the tool 2.

Comme illustré dans les figures 1 a et 1b, on notera également qu'une fois l'organe 1 correctement fixé à l'outil plan, les ergots 12, 13, 43 sont avantageusement tous noyés dans l'épaisseur e de l'outil plan 2 et ne ressortent donc pas à la surface supérieure 8 de l'outil plan 2. Cet agencement préféré évite toute présence de parties saillantes à la surface supérieure 8 de l'outil plan, et de ce fait écarte tout risque d'accrochage avec des organes de machine en mouvement dans la presse à platine comme les barres de pinces défilant précisément le long de cette surface supérieure. De plus, un tel agencement permet également d'écarter tout risque de blessure pour le machiniste qui doit manipuler de tels outils plans, notamment lors d'opération tels que les changements de ces outils durant la préparation de la machine.As illustrated in FIGS. 1a and 1b, it will also be noted that once the member 1 is correctly fixed to the plane tool, the lugs 12, 13, 43 are advantageously all embedded in the thickness e of the plane tool 2 and therefore do not emerge from the upper surface 8 of the planar tool 2. This preferred arrangement avoids the presence of protruding parts on the upper surface 8 of the planar tool, and thus eliminates any risk of snagging with moving machine members in the platen press as the clip bars scroll precisely along this upper surface. In addition, such an arrangement also avoids any risk of injury to the machinist who must handle such flat tools, especially during operations such as changes of these tools during the preparation of the machine.

Bien que le mécanisme 20 de la partie avant 10 soit préférentiellement reproduit dans la partie arrière 40 de l'organe 1, il n'est pas exclu de pouvoir disposer ce mécanisme seulement dans la partie avant ou dans la partie arrière de l'organe 1, voire à un autre endroit le long de l'organe 1.Although the mechanism 20 of the front portion 10 is preferably reproduced in the rear portion 40 of the member 1, it is not excluded to be able to have this mechanism only in the front part or in the rear part of the body 1 , or at another place along the organ 1.

Dans une autre variante, il pourrait être avantageux de prévoir un moyen de retenue bloquant le coulissement relatif des parties centrale et arrière afin de limiter la longueur de la course d'extension de l'organe 1, et par la même occasion d'empêcher toute séparation intempestive de ces deux parties lors de leur manipulation.In another variant, it could be advantageous to provide a retaining means blocking the relative sliding of the central and rear parts in order to limit the length of the extension stroke of the member 1, and at the same time to prevent any inadvertent separation of these two parts during handling.

On mentionnera finalement que les éléments constitutifs de l'organe 1 sont préférentiellement fabriqués en métal, comme l'acier ou l'aluminium, sans que cela en soit pour autant une nécessité. Aussi, bien qu'il pourrait être différent, le profil général de l'organe 1 est de section rectangulaire et son épaisseur dépend essentiellement de la rigidité du matériau employé, de la longueur maximale que peut avoir l'organe 1, ainsi que de l'effort qui doit être repris par l'outil plan 2 afin de pouvoir au moins résister à la plus forte contrainte pour laquelle il a été dimensionné. Enfin, tout en préservant une rigidité suffisante, il serait également possible d'alléger l'organe de la présente invention en prévoyant l'agencement d'une pluralité d'ouvertures dans les portions de parties 10, 30, 40 dépourvues de tout agencement particulier.Finally it will be mentioned that the constituent elements of the member 1 are preferably made of metal, such as steel or aluminum, without this being a necessity. Also, although it could be different, the general profile of the member 1 is of rectangular section and its thickness depends essentially on the rigidity of the material used, the maximum length that can have the member 1, as well as the effort that must be taken up by the tool plane 2 in order to be able to at least resist the strongest constraint for which it was dimensioned. Finally, while preserving sufficient rigidity, it would also be possible to lighten the body of the present invention by providing the arrangement a plurality of openings in the portion portions 10, 30, 40 devoid of any particular arrangement.

Claims (10)

  1. A means (1) for strengthening a flat tool (2) having a thickness (e) and formed with openings (6) each having a side (5), adapted for being used in a machine intended inter alia for the packing industry, characterised in that it comprises at least one fixed lug (12) and at least one movable lug (13) extending in the opposite direction to the fixed lug and driven by a mechanism (20) for fixing and withdrawing the means (1) from the flat tool (2) via the said lugs (12, 13), which are each adapted to engage the side (5) of one of the openings (6) formed for this purpose in the flat tool (2).
  2. A means (1) according to claim 1, characterised in that it has an elongate shape similar to that of a straight bar.
  3. A means (1) according to claim 2, characterised in that it has a narrow profile defining a top edge (3) which makes contact with a bottom surface (4) of the flat tool (2).
  4. A means (1) according to claim 1, characterised in that the fixed lug (12) and the movable lug (13) are embedded in the thickness (e) of the flat tool (2).
  5. A means (1) according to any of the preceding claims, characterised in that it is of variable length and comprises at least a front part (10) and a rear part (40) movable longitudinally relative to one another.
  6. A means (1) according to claim 5, characterised in that the rear part (40) slides along a central part (30) integral with the front part (10).
  7. A means (1) according to claim 5 or 6, characterised in that its rear part (40) comprises a stop (45) against which a clamping means belonging to the machine can bear and push the rear part (40) of the means (1) in the longitudinal direction so as to insert at least one lug (43) integral with the rear part (40) into the side (5) of the corresponding opening (6) in the flat tool (2).
  8. A means (1) according to claim 5, characterised in that the said mechanism (20) is disposed in the front part (10) and/or the rear part (40).
  9. A means (1) according to any of the preceding claims, characterised in that the movable lug (13) is driven in the longitudinal direction by the mechanism (20) which when closed pushes the movable lug (13) into the side (5) of the opening (6) and when open withdraws the movable lug (13) from the side (5), counteracting a resilient means (27).
  10. A means (1) according to any of claims 3 to 9, characterised in that it comprises at least one stabilising rib (18) mounted against the means (1) so that it can lean against the bottom surface (4) of the flat tool (2).
