Device for automatic marking of moulded articles, employing sliding rods fitted in a tool, which can, by virtue of their positions, generate on the article to be made a series of hollows, flats or reliefs used for transmitting a certain number of encoded data relating to the conditions of manufacture. Application as a code generator on moulded articles.

Description

DISPOSlllF DE MARQUAGE AUTOMATIOUE DE PIECES REALISEES PAR
MOULAGE
La présente invention se rapporte à un dispositif de marquage automatique de pièces réalisées par moulage, en particulier sur des installations fonctionnant en automatique.AUTOMATIC MARKING OF PARTS MADE BY
MOLDING
The present invention relates to an automatic marking device for parts produced by molding, in particular on installations operating automatically.

Ce marquage est réalisé au moyen d1 un codage.This marking is carried out by means of coding.

Le codage des pièces moulées peut être particulièrement intéressant afin d' assurer la mise au point d' une fabrication ou de permettre l'identification de pièces dites "de sécurité".The coding of the molded parts can be particularly interesting in order to ensure the development of a production or to allow the identification of so-called "safety" parts.

Ce codage peut Dorter sur l' identification en temps réel de la pièce réalisée - lour, heure, numéro d' ordre de 1' opération de moulage - ainsi que divers paramètres liés aux conditions de fabrication - caractéristiques du métal, du sable etc...This coding can depend on the real-time identification of the part produced - heavy, hour, serial number of the molding operation - as well as various parameters linked to the manufacturing conditions - characteristics of the metal, sand, etc. .

Les procédés de codage !labituellement utilisés tels que : mise en place d' index ou de chiffres sur le modèle, utilisation d' index rotatifs, impression directe dans 1' empreinte de divers signes, ne se prêtent pas facilement à une automatisation et ils ne peuvent transmettre qu un nombre réduit d'informations.The coding methods conventionally used such as: placing of indexes or figures on the model, use of rotary indexes, direct printing in the imprint of various signs, do not lend themselves easily to automation and they do not can transmit only a reduced amount of information.

De plus, ces informations ne peuvent être que difficilement décodées automatiquement.In addition, this information can only be difficult to decode automatically.

La présente invention a pour obiet un dispositif générateur d' éléments de codage particulièrement économique qui évite les inconvénients précités et qui est essentiellement caractérisé en ce qu'il comporte un certain nombre de tiges mobiles en translation, incorporées dans un outillage dont elles affleurent plus ou moins la surface et peuvent créer, en fonction de leurs positions, un certain nombre de creux, de plats ou de reliefs.The object of the present invention is a device for generating particularly economical coding elements which avoids the aforementioned drawbacks and which is essentially characterized in that it comprises a number of rods movable in translation, incorporated in a tool of which they are more or less flush. less the surface and can create, according to their positions, a certain number of hollows, dishes or reliefs.

Ces creux, ces plats ou ces reliefs ainsi créés, se retrouveront reproduits sur la pièce issue de cet outillage. These hollows, these dishes or these reliefs thus created will be reproduced on the part produced from this tool.

Un système logique de programmation associé à1' l'installation sera à même de commander à chaque opération de moulage la ou les tiges mobiles selon une combinaison représentative d' un code défini par 1' utilisateur. A logic programming system associated with the installation will be able to control at each molding operation the movable rod or rods according to a combination representative of a code defined by the user.

Selon la combinaison obtenue, ces tiges créeront à la surface de l'outillage une série de creux, de plats ou de reliefs plus ou moins accentués pouvant être assimilés à des éléments constitutifs d' un code.According to the combination obtained, these rods will create on the surface of the tool a series of hollows, dishes or more or less accentuated reliefs which can be assimilated to elements constituting a code.

Les informations pouvant être transmises par ce code sont d' autant plus riches que le nombre de tiges ainsi que le nombre de positions obtenues par ces tiges sont importants.The information that can be transmitted by this code is all the richer as the number of rods as well as the number of positions obtained by these rods are important.

Selon une variante préférée de réalisation, les tiges pourront occuper deux positions, créant de ce fait des combinaisons du type : creux/plats, plats/reliefs, creux/reliefs, pouvant être lus dans un système de numérotation de type binaire.According to a preferred embodiment, the rods can occupy two positions, thereby creating combinations of the type: hollow / flat, flat / raised, hollow / raised, which can be read in a binary type numbering system.

D' autres particularités de la présente invention apparaJtront dans la description suivante d' un mode de réalisation préféré d' un tel dispositif de marquage, donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels - la figure 1 représente une mise en oeuvre particulière de ce dispositif.Other features of the present invention will appear in the following description of a preferred embodiment of such a marking device, given by way of nonlimiting example, with reference to the accompanying drawings in which - Figure 1 shows a particular implementation of this device.

Les tiges 1, 1', 1" intégrée à un outillage 2, sont à même, à partir d' actionneurs 3, 3', 3" leur étant directement associés, de se positionner de façon indépendante à partir d'informations issues d' un système de commande logique 4.The rods 1, 1 ', 1 "integrated into a tool 2, are able, from actuators 3, 3', 3" being directly associated with them, to position themselves independently from information coming from a logic control system 4.

Selon leur positionnement, elles pourront créer à la surface de 1' outillage une série de creux 5, de plats 6, ou de reliefs 7.Depending on their positioning, they may create on the surface of the tool a series of hollows 5, dishes 6, or reliefs 7.

Une pièce 8 issue de cet outillage reproduira cette configuration représentative des informations à transmettre.A part 8 from this tool will reproduce this configuration representative of the information to be transmitted.

- la figure 2 représente une variante de ce système dans laquelle un outillage 10 comportant ces mêmes tiges 12, 12', 12" est utilisés pour réaliser une empreinte 13 dont sera issue la pièce 14 à fabriquer. - Figure 2 shows a variant of this system in which a tool 10 comprising these same rods 12, 12 ', 12 "is used to make an imprint 13 from which will come the part 14 to be manufactured.

Ces mêmes creux, plats ou reliefs se trouvent ainsi transférés de l'outillage à la pièce. These same hollows, flat or reliefs are thus transferred from the tool to the part.

- les figures 3, 4 et 5 représentent des variantes des divers mécanismes pouvant être utilisés pour une commande de tiges.- Figures 3, 4 and 5 show variants of the various mechanisms that can be used for rod control.

La figure 3 présente un système dans lequel la tige 21 est associée à un piston 22 soumis à une pression hydraulique ou pneumatique en 23 ou 23' et capable de positionner la tige selon deux états 24 ou 24'.FIG. 3 presents a system in which the rod 21 is associated with a piston 22 subjected to hydraulic or pneumatic pressure in 23 or 23 ′ and capable of positioning the rod in two states 24 or 24 ′.

La figure 4 présente une autre possibilité d'animation de la tige 31 au moyen d'un électro-aimant 32 selon au moins deux positions.Figure 4 shows another possibility of animation of the rod 31 by means of an electromagnet 32 in at least two positions.

La variante exprimée par la figure 5 consiste à animer les tiges 41, 41', 41" par l'intermédiaire d'un arbre à cames 42 entraîné en rotation par un moteur 43. The variant expressed by FIG. 5 consists in animating the rods 41, 41 ', 41 "by means of a camshaft 42 driven in rotation by a motor 43.
