Abstract

The process involves injection moulding the identification strip in a single piece as a strip with identification tags attached to a longitudinal edge of the strip by regions of reduced resistance (3). The next stage of fabrication has a machine that bends the tags through ninety degrees about the line of reduced resistance, then breaks them away from the edge of the strip. The separated tags are then inserted in corresponding mountings (8) formed in the moulding of the strip. In the third stage of fabrication the marking tags are printed using a rotating print roller. The strip is automatically advanced.

Description

La présente invention concerne un procédé de fabrication d'une barrette portant des bagues de marquage de câbles. Elle concerne également la barrette et les bagues de marquage obtenues par ce procédé.The present invention relates to a method of manufacturing a bar carrying cable marking rings. It also relates to the bar and the marking rings obtained by this process.

Dans le domaine du câblage électrique, il est connu d'utiliser des bagues de marquage pour identifier les câbles. Ces bagues sont généralement prévues sur une barrette de support, laquelle pouvant regrouper par exemple des bagues dont le marquage est identique. Pour faciliter le transport et le stockage de ces barrettes, il existe des coffrets ou des classeurs munis de rainures agencées pour recevoir lesdites barrettes et les positionner, de préférence, pour visualiser aisément les marquages prévus sur les bagues.In the field of electrical wiring, it is known to use marking rings to identify cables. These rings are generally provided on a support bar, which can group, for example, rings whose marking is identical. To facilitate the transport and storage of these bars, there are boxes or binders provided with grooves arranged to receive said bars and position them, preferably, to easily visualize the markings provided on the rings.

La publication européenne n° 479 668 décrit une réglette portant de manière détachable des repères, la réglette et les repères étant réalisés d'un seul tenant en matière synthétique injectée. Ces repères sont ensuite imprimés puis la réglette est rangée dans un classeur correspondant. Au moment de l'utilisation de ce type de repères, l'utilisateur doit, avec un outil approprié détaché le repère de la réglette en arrachant les points d'attache liant solidairement le repère à sa réglette. L'utilisateur doit donc appliquer sur le repère, à l'aide de son outil, une traction combinée à un mouvement de rotation pour réussir à rompre lesdits points d'attache. Il arrive cependant que l'outil tourne à l'intérieur du repère pendant le mouvement d'arrachage. Il est alors difficile de rompre les points d'attache. Par conséquent, il ressort clairement que ce type de repères ne peut pas être prélevé instantanément et que l'utilisateur perd un temps précieux à détacher chaque repère de sa réglette.European publication No. 479 668 describes a strip detachably bearing marks, the strip and marks being made in one piece from injected synthetic material. These marks are then printed and the strip is stored in a corresponding filing cabinet. When using this type of marker, the user must, with an appropriate tool, detach the marker from the strip by tearing off the attachment points connecting the marker solidly to his strip. The user must therefore apply to the mark, using his tool, traction combined with a rotational movement to succeed in breaking said attachment points. However, sometimes the tool turns inside the mark during the tear-off movement. It is therefore difficult to break the attachment points. Consequently, it is clear that this type of markers cannot be removed instantaneously and that the user spends precious time detaching each mark from his strip.

La présente invention se propose de pallier les inconvénients mentionnés ci-dessus en proposant une barrette portant de manière amovible des bagues de marquage de façon à faciliter le prélèvement desdites bagues tout en garantissant un bon maintien des bagues dans ladite barrette, cette barrette et ces bagues étant réalisées préalablement d'une seule pièce.The present invention proposes to overcome the drawbacks mentioned above by proposing a bar removably carrying marking rings so as to facilitate the removal of said rings while ensuring good retention of the rings in said bar, this bar and these rings being made beforehand in one piece.

Ce but est atteint par un procédé de fabrication d'une barrette portant des bagues de marquage caractérisé en ce qu'il comporte les deux phases de fabrication suivantes :

  • moulage par injection en une seule pièce d'une barrette et d'une pluralité de bagues de marquage, les bagues étant reliées à un bord longitudinal de ladite barrette par des lignes de liaison de moindre résistance,
  • mise en place des bagues dans la barrette par des moyens mécaniques continus prévoyant le basculement des bagues de 90° autour desdites lignes de liaison sur ladite barrette, la séparation des bagues en rompant lesdites lignes de liaison et l'insertion des bagues libres dans des logements de maintien correspondants ménagés sur ladite barrette.
This object is achieved by a method of manufacturing a bar carrying marking rings characterized in that it comprises the following two manufacturing phases:
  • injection molding in a single piece of a strip and a plurality of marking rings, the rings being connected to a longitudinal edge of said strip by connecting lines of less resistance,
  • positioning of the rings in the bar by continuous mechanical means providing for the tilting of the rings by 90 ° around the said connecting lines on the said bar, the separation of the rings by breaking the said connecting lines and the insertion of the free rings in housings corresponding holding formed on said strip.

Selon une forme de réalisation préférée, pour réaliser la deuxième phase de fabrication, on utilise une rampe hélicoïdale sur 90° agencée pour basculer les bagues sur la barrette et une rampe de positionnement agencée pour exercer une poussée sur lesdites bagues de manière à les séparer de la barrette et à les introduire dans leur logement correspondant.According to a preferred embodiment, to carry out the second manufacturing phase, a 90 ° helical ramp is used which is arranged to tilt the rings on the bar and a positioning ramp which is arranged to exert a thrust on said rings so as to separate them from the bar and insert them into their corresponding housing.

Le procédé de fabrication peut comporter une troisième phase de fabrication dans laquelle les bagues de marquage sont imprimées en continu, au moyen d'un rouleau d'impression rotatif.The manufacturing process may include a third manufacturing phase in which the marking rings are printed continuously, by means of a rotary printing roller.

De préférence, les deuxième et troisième phases de fabrication se succèdent sur une chaîne de fabrication continue et des moyens d'avance continue sont prévus en correspondance sur ladite chaîne et sur les barrettes portant lesdites bagues.Preferably, the second and third manufacturing phases follow one another on a continuous production line and continuous advance means are provided in correspondence on said chain and on the bars carrying said rings.

Le but mentionné ci-dessus est également atteint par une barrette telle que définie en préambule et caractérisée en ce qu'elle est réalisée dans une matière synthétique moulée par injection en une seule pièce avec une pluralité de bagues, ces dernières étant reliées à un bord longitudinal de la barrette par des lignes de liaison de moindre résistance et en ce que les bagues sont ensuite détachées de la barrette et insérées de manière amovible dans des logements de maintien prévus sur ladite barrette.The object mentioned above is also achieved by a bar as defined in the preamble and characterized in that it is made of a synthetic material injection molded in one piece with a plurality of rings, the latter being connected to a longitudinal edge of the bar by connecting lines of less resistance and in that the rings are then detached from the bar and inserted in a removable manner in holding housings provided on said bar.

Dans une forme de réalisation préférée, elle comporte une base plane sur laquelle sont ménagés les logements de maintien pour lesdites bagues.In a preferred embodiment, it comprises a flat base on which the holding housings for said rings are formed.

Les logements de maintien sont avantageusement définis par une pluralité de rainures en relief, parallèles, prévues sur ladite barrette, deux rainures consécutives délimitant un logement.The holding housings are advantageously defined by a plurality of grooves in relief, parallel, provided on said bar, two consecutive grooves delimiting a housing.

De préférence, chaque rainure comporte dans une partie avant au moins un chanfrein agencé pour faciliter le positionnement et l'introduction de la bague dans son logement correspondant pendant qu'elle est basculée sur ladite barrette.Preferably, each groove comprises in a front part at least one chamfer arranged to facilitate the positioning and the introduction of the ring into its corresponding housing while it is tilted on said bar.

Chaque logement peut comporter deux bords latéraux saillants opposés définissant deux rails de guidage pour les bords latéraux correspondants d'une bague et une butée d'alignement agencée pour aligner lesdites bagues.Each housing may comprise two opposite projecting lateral edges defining two guide rails for the corresponding lateral edges of a ring and an alignment stop arranged to align said rings.

Chaque butée d'alignement peut être définie par un rétrécissement d'une partie arrière du logement correspondant, ce rétrécissement pouvant être obtenu par le prolongement desdits bords saillants dans la partie arrière de chaque logement.Each alignment stop can be defined by a narrowing of a rear part of the corresponding housing, this narrowing being obtainable by the extension of said projecting edges in the rear part of each housing.

Dans la forme de réalisation préférée, la barrette comporte, au dos de sa base plane, des dents successives formant une crémaillère agencée pour coopérer avec des moyens de transport complémentaires associés à ladite chaîne de fabrication.In the preferred embodiment, the bar comprises, on the back of its flat base, successive teeth forming a rack arranged to cooperate with complementary means of transport associated with said production line.

Le but mentionné ci-dessus est également atteint par une bague de marquage, constituée d'un plot sensiblement cubique pourvu d'une face avant prévue pour recevoir un marquage, d'une face arrière, de deux parois latérales et d'un orifice central traversant et caractérisée en ce qu'elle est réalisée en matière synthétique moulée par injection en une seule pièce avec ladite barrette, la bague étant reliée à un bord longitudinal de la barrette par une ligne de liaison de moindre résistance et en ce qu'elle est ensuite basculée sur ladite barrette, détachée d'elle puis insérée de manière amovible dans un logement de maintien correspondant prévu sur cette barrette.The above-mentioned object is also achieved by a marking ring, consisting of a substantially cubic stud provided with a front face intended to receive a marking, on a rear face, of two walls lateral and a central through hole and characterized in that it is made of synthetic material injection molded in one piece with said strip, the ring being connected to a longitudinal edge of the strip by a connecting line of less resistance and in that it is then tilted on said bar, detached from it then inserted in a removable manner in a corresponding holding housing provided on this bar.

Selon une forme de réalisation préférée, elle comporte deux gorges latérales de forme complémentaire aux rails de guidage prévus dans un logement de maintien ménagé sur ladite barrette.According to a preferred embodiment, it comprises two lateral grooves of shape complementary to the guide rails provided in a retaining housing formed on said strip.

La présente invention et ses avantages apparaîtront mieux dans la description suivante d'un exemple de réalisation, en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une vue de dessus partielle d'une barrette et de plusieurs bagues de marquage en cours de fabrication selon le procédé de l'invention,
  • la figure 2 est une vue en coupe transversale de la figure 1 selon la ligne ll-ll,
  • la figure 3 est une vue de dessus partielle d'une barrette et de plusieurs bagues en fin de fabrication selon le procédé de l'invention, et
  • la figure 4 est une vue en coupe longitudinale de la figure 3 selon la ligne IV-IV.
The present invention and its advantages will appear more clearly in the following description of an exemplary embodiment, with reference to the appended drawings, in which:
  • FIG. 1 is a partial top view of a bar and of several marking rings during manufacture according to the method of the invention,
  • FIG. 2 is a cross-sectional view of FIG. 1 along the line II-II,
  • FIG. 3 is a partial top view of a bar and of several rings at the end of manufacture according to the method of the invention, and
  • Figure 4 is a longitudinal sectional view of Figure 3 along the line IV-IV.

Les figures 1 et 2 illustrent une barrette 1 et des bagues de marquage 2 telles que réalisées d'une seule pièce en matière synthétique par un procédé d'injection ou un autre procédé approprié. Comme illustré, les bagues 2 sont reliées perpendiculairement à la barrette 1, le long d'un de ses bords longitudinaux par des lignes de liaison 3 de moindre résistance.Figures 1 and 2 illustrate a bar 1 and marking rings 2 as made in one piece from synthetic material by an injection process or another suitable process. As illustrated, the rings 2 are connected perpendicularly to the bar 1, along one of its longitudinal edges by connecting lines 3 of less resistance.

La barrette 1 comporte une base plane 4 supportée par deux pieds longitudinaux 5 et prolongée, sur le bord longitudinal opposé à celui portant les bagues 2, par une patte inclinée 6 agencée pour coopérer avec une rainure correspondante prévue dans un coffret ou classeur de rangement approprié (non représenté). La barrette 1 comporte, sur sa base plane 4, des rainures saillantes 7 orientées perpendiculairement au sens longitudinal de la barrette 1, ces rainures 7 définissant entre elles des logements de maintien 8 pour lesdites bagues de marquage 2. Chaque rainure 7 est disposée sensiblement entre deux bagues 2 pour que le logement 8 soit en correspondance avec une de ces bagues 1. Ces rainures 7 comportent dans une partie avant un chanfrein 7', cassant les arêtes vives délimitant ces rainures et facilitant ainsi l'introduction et le positionnement de la bague 2 entre deux rainures consécutives au moment où elle est basculée sur la base plane 4 de la barrette 1. Sans la présence de ces chanfreins 7', les bagues 2 risqueraient de rester accrochées auxdites arêtes vives et ne pourraient alors être mises en place dans leur logement 8. Chaque rainure 7 comporte de part et d'autre deux bords saillants 9 parallèles à ladite base plane 4 de la barrette 1 et définissant des rails de guidage 10 pour les bords latéraux correspondants des bagues 2. De plus, les bords saillants 9 présentent dans une partie arrière un prolongement 11 qui rétrécit lesdits logements 8 pour former une butée d'alignement 12 desdites bagues 2 une fois montées. Pour faciliter l'insertion des bagues 2 dans les logements 8, une partie avant des bords saillants 7 est pourvue d'un biseau 13. La barrette 1 comporte encore sur un de ses pieds longitudinaux 5 des dents 14 successives formant une crémaillère 15. Cette crémaillère 15 est utilisée dans le cadre du procédé de fabrication notamment comme moyens d'avance automatique des barrettes 1 sur une chaîne de transport continu pourvue de moyens de transport complémentaires, tels que des pignons successifs, une chaîne munie d'ergots d'entraînement, une courroie crantée, etc.The bar 1 has a flat base 4 supported by two longitudinal feet 5 and extended, on the longitudinal edge opposite to that carrying the rings 2, by an inclined tab 6 arranged to cooperate with a corresponding groove provided in a suitable storage cabinet or filing cabinet (not shown). The bar 1 comprises, on its flat base 4, projecting grooves 7 oriented perpendicular to the longitudinal direction of the bar 1, these grooves 7 defining between them holding housings 8 for said marking rings 2. Each groove 7 is disposed substantially between two rings 2 so that the housing 8 is in correspondence with one of these rings 1. These grooves 7 have in a front part a chamfer 7 ', breaking the sharp edges delimiting these grooves and thus facilitating the introduction and positioning of the ring 2 between two consecutive grooves when it is tilted on the flat base 4 of the bar 1. Without the presence of these chamfers 7 ′, the rings 2 would risk remaining attached to said sharp edges and could then not be put in place in their housing 8. Each groove 7 has on either side two projecting edges 9 parallel to said flat base 4 of the bar 1 and defining gu rails idage 10 for the corresponding lateral edges of the rings 2. In addition, the projecting edges 9 have, in a rear part, an extension 11 which narrows said housings 8 to form an alignment stop 12 of said rings 2 once mounted. To facilitate the insertion of the rings 2 in the housings 8, a front part of the projecting edges 7 is provided with a bevel 13. The bar 1 also has on one of its longitudinal feet 5 successive teeth 14 forming a rack 15. This rack 15 is used in the context of the manufacturing process, in particular as means for automatically advancing bars 1 on a continuous transport chain provided with complementary transport means, such as successive sprockets, a chain provided with drive pins, a toothed belt, etc.

Les bagues 2 comportent un plot 16 de forme sensiblement cubique présentant une face avant 17 prévue pour recevoir un marquage 17', une face arrière 18, deux parois latérales 19 et un orifice central traversant 20. Les parois latérales 19 sont pourvues d'une gorge 21 de forme complémentaire à celle des rails 10 formés par les bords saillants 9 des rainures 7 prévues sur la barrette 1. Les bagues 2 comportent un chanfrein 22 sur une arête de leur face arrière 18 qui facilite le montage ultérieur de la bague dans un porte-repère approprié. L'orifice central traversant 20 prévu dans la bague 2 permet l'introduction d'un outil approprié (non représenté) permettant de prélever ladite bague de marquage 2 et de l'introduire dans ledit porte-repère (non représenté).The rings 2 comprise a stud 16 of substantially cubic shape having a front face 17 intended to receive a marking 17 ′, a rear face 18, two side walls 19 and a central through hole 20. The side walls 19 are provided with a groove 21 of shape complementary to that of the rails 10 formed by the projecting edges 9 of the grooves 7 provided on the bar 1. The rings 2 have a chamfer 22 on an edge of their rear face 18 which facilitates the subsequent mounting of the ring in an appropriate marker carrier . The central through hole 20 provided in the ring 2 allows the introduction of an appropriate tool (not shown) for removing said marking ring 2 and introducing it into said marker carrier (not shown).

Les figures 3 et 4 illustrent la barrette 1 et les bagues de marquage 2 correspondant aux figures précédentes, les bagues 2 étant séparées de la barrette 1 et montées de manière amovible dans les logements de maintien 8. Ces bagues 2 sont alignées grâce aux butées 12 prévues dans les logements 8. Pour passer de la configuration des figures 1 et 2 à celle des figures 3 et 4, le procédé de fabrication prévoit par exemple l'utilisation d'une rampe hélicoïdale fixe, qui décrit un angle de 90° et qui est agencée pour basculer les bagues 2 sur la base plane 4 de la barrette 1 autour de leur ligne de liaison 3. Une rampe de positionnement fixe, prévue à la suite de la rampe hélicoïdale, est agencée pour exercer une poussée sur les bagues 2 permettant de les détacher de la barrette 1 en rompant les lignes de liaison 3, de les déplacer transversalement pour les insérer dans leur logement 8 respectif. Cette phase de fabrication est réalisée d'une manière continue, la barrette 1 se déplaçant sur une chaîne de transport au moyen d'une crémaillère 15 prévue au dos de la barrette et coopérant avec des moyens de transport complémentaires prévus sur ladite chaîne.Figures 3 and 4 illustrate the bar 1 and the marking rings 2 corresponding to the previous figures, the rings 2 being separated from the bar 1 and removably mounted in the holding housings 8. These rings 2 are aligned by means of the stops 12 provided in the housings 8. To pass from the configuration of FIGS. 1 and 2 to that of FIGS. 3 and 4, the manufacturing process provides for example the use of a fixed helical ramp, which describes an angle of 90 ° and which is arranged to tilt the rings 2 on the flat base 4 of the bar 1 around their connecting line 3. A fixed positioning ramp, provided following the helical ramp, is arranged to exert a thrust on the rings 2 allowing to detach them from the bar 1 by breaking the connecting lines 3, to move them transversely to insert them in their respective housing 8. This manufacturing phase is carried out continuously, the bar 1 moving on a transport chain by means of a rack 15 provided on the back of the bar and cooperating with additional transport means provided on said chain.

Le procédé de fabrication est avantageusement complété par une unité d'impression en continu des bagues (non représenté), notamment au moyen d'un rouleau rotatif d'impression à chaud. La rotation du rouleau est alors réglée en synchronisme avec l'avance de la barrette 1. En fin d'impression, la barrette 1 portant lesdites bagues marquées 2 peut être rangée dans un coffret ou classeur approprié (non représenté).The manufacturing process is advantageously supplemented by a continuous printing unit for the rings (not shown), in particular by means of a rotary hot-printing roller. The rotation of the roller is then adjusted in synchronism with the advance of the bar 1. At the end of printing, the bar 1 carrying said rings marked 2 can be stored in an appropriate box or file (not shown).

Lors de l'utilisation, l'opérateur chargé du repérage d'un circuit électrique ou d'un câblage sélectionne les barrettes de bagues 1 dont il a besoin dans un coffret. A l'aide de son outil, il prélève simplement et rapidement les bagues de marquage 2 nécessaires et les introduit dans un porte-repère qui sera monté sur le câble électrique à identifier. Pour ce faire, il introduit l'outil dans l'orifice 20 de la bague 2 du côté opposé à la butée d'alignement 12 de manière à pouvoir dégager la bague 2 de son logement 8 en la faisant pivoter par un mouvement de rotation exercé avec l'outil. L'insertion de la bague 2 dans son porte-repère est facilitée par le chanfrein 22.During use, the operator responsible for locating an electrical circuit or a wiring selects the ring bars 1 which he needs in a box. Using his tool, he easily and quickly removes the rings marking 2 necessary and introduces them in a reference holder which will be mounted on the electric cable to be identified. To do this, he introduces the tool into the orifice 20 of the ring 2 on the side opposite to the alignment stop 12 so as to be able to disengage the ring 2 from its housing 8 by making it pivot by a rotational movement exerted with the tool. The insertion of the ring 2 into its reference carrier is facilitated by the chamfer 22.

La présente invention n'est pas limitée à l'exemple de réalisation décrit mais s'étend à toute modification et variante évidente pour un homme du métier, l'essentiel étant que les bagues 2 soient formées d'une seule pièce avec ladite barrette 1 et qu'elles soient ensuite séparées de la barrette 1 et maintenues de manière amovible dans un logement 8 approprié prévu sur ladite barrette 1. La forme des bagues 2 et des logements 1 illustrée dans l'exemple décrit n'est pas limitatif, l'essentiel étant que les bagues 2 puissent être maintenues dans des logements 8 de forme complémentaire.The present invention is not limited to the embodiment described but extends to any modification and variant obvious to a person skilled in the art, the main thing being that the rings 2 are formed in one piece with said bar 1 and that they are then separated from the bar 1 and detachably held in an appropriate housing 8 provided on said bar 1. The shape of the rings 2 and of the housings 1 illustrated in the example described is not limiting, the essential being that the rings 2 can be maintained in housings 8 of complementary shape.
