Description

Domaine de l'inventionField of invention

Le domaine de la présente invention concerne celui des procédés de fixation et plus notament celui des procédés de sertissage. Elle concerne particulièrement, mais pas exclusivement, le domaine des riveteuses.The field of the present invention concerns that of fastening methods and more particularly that of crimping methods. It concerns particularly, but not exclusively, the field of riveters.

Art antérieurPrior art

De nos jours, les rivets sont fixés sur des supports comme par exemple le cuir par des procédés manuels ou à énergie pneumatique. Ces procédés sont d'une précision limitée, peu ergonomiques et longs.Par ailleurs, ils ne présentent pas de contrôle faisant apparaître les éventuels défauts de sertissage. Les machines mettant en oeuvre ces procédés ne permettent pas de garantir une homogénéité de la mise en oeuvre de celui-ci car tous les opérateurs pouvent en modifier les paramètres.Nowadays, rivets are fixed on supports such as leather by manual or pneumatic energy processes. These processes are of limited precision, not very ergonomic and long. Furthermore, they do not have any control to reveal possible crimping defects. The machines implementing these processes do not guarantee homogeneity of the implementation of the latter because all the operators can modify the parameters.

Par ailleurs, dans un processus de personalisation d'article en cuir, par exemple, il n'est pas possible de sertir différents rivets sur un même article en cuir tout en appliquant la bonne pression de sertissage et/ou la bonne course de sertissage. En effet,si ces paramètres ou au moins un de ces paramètres de sertissage n'est pas correctement appliqué au rivet, ce dernier finira par se détacher de l'article. Or l'un des critères qui permettent de juger de la qualité d'un finition est la tenue dans le temps.Furthermore, in a leather item customization process, for example, it is not possible to set different rivets on the same leather item while applying the correct crimping pressure and/or the correct crimping stroke. Indeed, if these parameters or at least one of these crimping parameters is not correctly applied to the rivet, the latter will eventually detach from the item. However, one of the criteria used to judge the quality of a finish is its durability.

Le document US2014/025196A1 divulgue une méthode de soudage à l'arc comprenant un dispositif de lectrude d'une étiquette associée à une position du support de soudage. Une telle méthode n'est pas appropriée pour effectuer un bon sertissage de rivets sur des articles en cuir.The document US2014/025196A1 discloses an arc welding method comprising a device for emitting a label associated with a position of the welding support. Such a method is not suitable for performing a good setting of rivets on leather articles.

Le document US2011/113613A1 divulgue un procédé d'assemblage d'un boulon comprenant une étape de reconnaissance de la vis et de l'écrou par un système de lecture. Un tel procédé n'est pas adapté pour le sertissage fin de rivets sur un article en cuir.The document US2011/113613A1 discloses a method of assembling a bolt comprising a step of recognizing the screw and the nut by a reading system. Such a method is not suitable for the fine crimping of rivets on a leather article.

Dans la description détaillée qui va suivre des figures définies ci-dessus, les mêmes éléments ou les éléments remplissant des fonctions identiques pourront conserver les mêmes références de manière à simplifier la compréhension de l'invention.In the detailed description which follows of the figures defined above, the same elements or elements fulfilling identical functions may retain the same references so as to simplify the understanding of the invention.

La figure 1 représente un schéma du procédé de sertissage 100 selon l'invention. Ce procédé de sertissage, mise en oeuvre par un dispositif de sertissage 400, est destiné à sertir un accessoire de sertissage 200, représenté sur la figure 2, sur au moins un support 990 en cuir.There figure 1 represents a diagram of the crimping method 100 according to the invention. This crimping method, implemented by a crimping device 400, is intended to crimp a crimping accessory 200, represented in the figure 2 , on at least one 990 leather support.

Le dispositif de sertissage 400, mentionné précédemment et représenté sur la figure 3, comprend une unité de contrôle 410, configuré pour mettre en oeuvre le procédé de sertissage 100, et un organe de sélection.The crimping device 400, previously mentioned and shown in the figure 3 , comprises a control unit 410, configured to implement the crimping method 100, and a selection member.

Cet organe de sélection peut, de par sa configuration, proposer une sélection ou sélectionner l'accessoire de sertissage 200 et/ou un outil de sertissage 300. This selection member can, by its configuration, propose a selection or select the crimping accessory 200 and/or a crimping tool 300.

Cette étape de sélection 110 peut comprendre une étape d'identification 115 de l'accessoire de sertissage 200 et/ou de l'outil de sertissage 300 de sorte que l'accessoire de sertissage et/ou de l'outil de sertissage soient identifiés.This selection step 110 may comprise a step 115 of identifying the crimping accessory 200 and/or the crimping tool 300 so that the crimping accessory and/or the crimping tool are identified.

En effet, l'organe de sélection 420 peut se présenter sous la forme d'un organe d'assemblage 421 configuré pour recevoir un organe d'identification 315 de l'outil de sertissage 300 à la manière d'une clé et d'une serrure ou de deux objets complémentaires de sorte que l'outil de sertissage 300 soit identifié lors de son assemblage au dispositif de sertissage. En effet, l'organe d'identification 315 permet l'identification 115 de l'outil de sertissage 300 avant ou pendant son assemblage à l'organe de sélection 420. Indeed, the selection member 420 may be in the form of an assembly member 421 configured to receive an identification member 315 of the crimping tool 300 in the manner of a key and a lock or of two complementary objects so that the crimping tool 300 is identified during its assembly to the crimping device. Indeed, the identification member 315 allows the identification 115 of the crimping tool 300 before or during its assembly to the selection member 420.

Cette identification 115 de l'accessoire de sertissage 200 et/ou de l'outil de sertissage 300 peut également être réalisée par identification optique 116, identification électrique 117, identification radio 118 et/ou identification magnétique 119. This identification 115 of the crimping accessory 200 and/or the crimping tool 300 can also be carried out by optical identification 116, electrical identification 117, radio identification 118 and/or magnetic identification 119.

Effectivement, l'organe de sélection 420 peut également comprendre :

  • un dispositif optique 416 tel un lecteur de code barre, QR-Code et/ou une caméra par exemple,
  • un dispositif électrique 417 tel un lecteur de puce, et/ou un lecteur d'impédance par exemple,
  • un dispositif radio 418 tel qu'un lecteur d'étiquette RFID par exemple, et/ou
  • un dispositif magnétique 419 tel qu'un lecteur de bande magnétique par exemple.
Indeed, the selection organ 420 can also comprise:
  • an optical device 416 such as a barcode reader, QR-Code and/or a camera for example,
  • an electrical device 417 such as a chip reader, and/or an impedance reader for example,
  • a 418 radio device such as an RFID tag reader for example, and/or
  • a magnetic device 419 such as a magnetic stripe reader for example.

Ces différentes options permettent à l'organe de sélection 420 de sélectionner en identifiant ou d'identifier l'accessoire de sertissage 200 et/ou de l'outil de sertissage 300. En contre partie, l'accessoire de sertissage 200 peut comprendre un élément d'identification 215 configuré pour être identifié tel un code barre, un QR-Code, des caractéristiques visuels reconnaissable par une caméra, une puce, une impédance particulière, une étiquette RFID et/ou une bande magnétique.These different options allow the selection member 420 to select by identifying or to identify the crimping accessory 200 and/or the crimping tool 300. In return, the crimping accessory 200 can comprise an identification element 215 configured to be identified such as a bar code, a QR code, visual characteristics recognizable by a camera, a chip, a particular impedance, an RFID tag and/or a magnetic strip.

Parallèlement ou indépendamment à l'élément d'identification 215, l'organe d'identification 315 peut comprendre un code barre, un QR-Code, des caractéristiques visuelles reconnaissable par une caméra, un puce, une impédance particulière, une étiquette RFID et/ou une bande magnétique pour pouvoir être identifié.In parallel or independently of the identification element 215, the identification member 315 can comprise a bar code, a QR code, visual characteristics recognizable by a camera, a chip, a particular impedance, an RFID tag and/or a magnetic strip to be able to be identified.

En plus de l'identification de l'accessoire de sertissage 200 et/ou de l'outil de sertissage 300, l'élément d'identification 215 et/ou l'organe d'identification 315 comprennent un ensemble de paramètres 190 de sertissage de sorte que l'accessoire de sertissage 200 soit convenablement serti.In addition to identifying the crimping accessory 200 and/or the crimping tool 300, the identification element 215 and/or the identification member 315 include a set of crimping parameters 190 so that the crimping accessory 200 is properly crimped.

Cet ensemble paramètre de sertissage 190 comprend un paramètre de pression de sertissage 193 et un paramètre de course de sertissage 194 de sorte que la pression et la course de sertissage soient réalisées en fonction de l'accessoire de sertissage 200 sélectionné et/ou de l'outil de sertissage 300 sélectionné lorsque le procédé de sertissage 100 est mis en oeuvre.This crimping parameter set 190 includes a crimping pressure parameter 193 and a crimping stroke parameter 194 such that the crimping pressure and stroke are performed depending on the selected crimping accessory 200 and/or the selected crimping tool 300 when the crimping method 100 is implemented.

Ce procédé de sertissage 100 comprend plusieurs étapes, comme par exemple une étape de sélection de l'accessoire de sertissage 200 et/ou de l'un outil de sertissage 300, comme décrit précédemment, une étape d'établissement, d'application et de maintien de l'ensemble de paramètres vu précédemment.This crimping method 100 comprises several steps, such as for example a step of selecting the crimping accessory 200 and/or a crimping tool 300, as described previously, a step of establishing, applying and maintaining the set of parameters seen previously.

En effet, lorsque l'accessoire de sertissage 200 est sélectionné pour être serti sur au moins un support 990 en cuir, ou sur un complexe, c'est-à-dire sur un empilement de support en cuir comprenant au moins un premier support en cuir 991 et un deuxième support en cuir 992 comme représenté sur la figure 1, ou lorsque un outil de sertissage 300 pour sertir l'accessoire de sertissage 200 est sélectionné ou lorsque les deux sont sélectionnés une étape d'établissement 120 suit l'étape de sélection 110. Indeed, when the crimping accessory 200 is selected to be crimped on at least one leather support 990 , or on a complex, that is to say on a stack of leather supports comprising at least a first leather support 991 and a second leather support 992 as shown in the figure 1 , or when a crimping tool 300 for crimping the crimping accessory 200 is selected or when both are selected an establishment step 120 follows the selection step 110.

Lors de cette étape d'établissement 120, l'ensemble de paramètres de sertissage 190 est établi en fonction de l'accessoire de sertissage 200 sélectionné et/ou de l'outil de sertissage 300 sélectionné et plus particulièrement en fonction de l'élément d'identification 215 et/ou de l'organe d'identification 315. En effet, cette étape d'établissement utilise l'élément d'identification 215 et/ou de l'organe d'identification 315 pour connaître les paramètres de sertissage 190 ou pour faire appel à des paramètres de sertissage 190 localisés dans une mémoire interne ou dans une base de données.During this establishment step 120, the set of crimping parameters 190 is established as a function of the selected crimping accessory 200 and/or the selected crimping tool 300 and more particularly as a function of the identification element 215 and/or the identification member 315. Indeed, this establishment step uses the identification element 215 and/or the identification member 315 to know the crimping parameters 190 or to call upon crimping parameters 190 located in an internal memory or in a database.

Une fois établi, le dispositif de sertissage applique à l'accessoire de sertissage 200, par l'intermédiaire de l'outil de sertissage 300 éventuellement sélectionné, l'ensemble de paramètres de sertissage 190 établi de sorte à sertir l'accessoire de sertissage 200 au support 990. L'application 130 de cet ensemble de paramètres de sertissage 190 peut être effectuée en fonction du temps 192 ou selon une courbe fonction du temps comme cela est représenté sur la figure 4.Once established, the crimping device applies to the crimping accessory 200, via the crimping tool 300 possibly selected, the set of crimping parameters 190 established so as to crimp the crimping accessory 200 to the support 990. The application 130 of this set of crimping parameters 190 can be carried out as a function of time 192 or according to a time-dependent curve as shown in FIG. figure 4 .

L'application de ce paramètre de pression de sertissage 193 est contrôlée par un asservissement en boucle ouverte, représenté sur la figure 5, de sorte à contrôler le sertissage de l'accessoire de sertissage tout au long de cette étape d'application 130. The application of this crimping pressure parameter 193 is controlled by an open loop servo, shown in the figure 5 , so as to control the crimping of the crimping accessory throughout this application step 130.

En effet, lorsque le paramètre de pression de sertissage 193 est contrôlé par un asservissement en boucle ouverte, le maintien de l'ensemble de paramètres de sertissage 190 est déclenché lorsque la course de sertissage rencontre un organe de butée déplaçable 493 ce qui a pour conséquence de maintenir, ou de stabiliser, l'ensemble de paramètres de sertissage pendant une période de maintien 191. Indeed, when the crimping pressure parameter 193 is controlled by an open-loop servocontrol, the maintenance of the set of crimping parameters 190 is triggered when the crimping stroke encounters a movable stop member 493, which has the consequence of maintaining, or stabilizing, the set of crimping parameters during a maintenance period 191.

Le paramètre de course de sertissage 194, quant à lui, est contrôlé par un asservissement en boucle ouverte, et de préférence par le déplacement de l'organe de butée déplaçable 493 qui permet d'arrêter la course de sertissage et éviter de marquer le support, c'est-à-dire le cuir, si l'asservissement de la pression de sertissage serait trop long ou si l'accessoire de sertissage venait soudainement à céder.The crimping stroke parameter 194, for its part, is controlled by an open-loop servocontrol, and preferably by the movement of the movable stop member 493 which makes it possible to stop the crimping stroke and avoid marking the support, i.e. the leather, if the servocontrol of the crimping pressure would be too long or if the crimping accessory were to suddenly give way.

L'application 130 de cet ensemble de paramètres de sertissage 190 à l'accessoire de sertissage 200 et suivit d'une étape de maintien cet ensemble de paramètres de sertissage 190 pendant une période de maintien 191 de sorte que la déformation de l'accessoire de sertissage 200 se réalise uniformément.The application 130 of this set of crimping parameters 190 to the crimping accessory 200 and followed by a step of maintaining this set of crimping parameters 190 for a holding period 191 so that the deformation of the crimping accessory 200 is carried out uniformly.
