Description

La présente invention a pour objet une forme pour la fabrication de chaussures.The subject of the present invention is a form for manufacturing shoes.

Dans le cas de certaines chaussures qui comportent une tige en matière synthétique, ou destinées à être associées à des pièces en matière synthétique ou en caoutchouc, il est connu de mettre en oeuvre des formes équipées de moyens de chauffage. Ces formes sont réalisées en aluminium, contiennent une résistance de chauffage, et sont reliées à une source d'alimentation électrique. Il convient toutefois de préparer la tige sur une forme en matière synthétique, puis de réaliser son transfert sur la forme chauffante en aluminium, pour réaliser les opérations devant s'effectuer à une certaine température, avant de replacer la tige sur une forme en matière synthétique pour réaliser les opérations de finition, telles que les opérations d'ébavurage.In the case of certain shoes which have an upper synthetic material, or intended to be associated with pieces of material synthetic or rubber, it is known to use forms equipped with heating means. These shapes are made of aluminum, contain a heating resistor, and are connected to a source power supply. However, the stem should be prepared on a plastic form, then transfer it to the form aluminum heater, to carry out the operations to be carried out at a certain temperature, before replacing the rod on a synthetic material for performing finishing operations, such as Deburring operations.

Il faut également tenir compte du fait qu'il faut non seulement chauffer la forme pour réaliser la vulcanisation de caoutchouc, mais également pour réactiver certaines colles, ou pour permettre le galbage de forme thermoplastique. Il est tout à fait clair que le passage d'une forme à une autre est une opération délicate, qui prend du temps, et qui risque de détériorer la tige.You also have to take into account that not only heat the form to vulcanize rubber, but also to reactivate certain adhesives, or to allow curving of thermoplastic form. It is quite clear that the transition from one form to another is a delicate operation, which takes time, and which risks deteriorate the stem.

Le but de l'invention est de fournir une forme pour la fabrication de chaussures, qui permette la réalisation de toutes les opérations nécessaires, notamment dans le cadre d'une automatisation des tâches, en permettant le chauffage ou le maintien à une température déterminée de la forme et par suite de la tige, lors du transfert de celle-ci entre deux postes, ou à certains postes de travail.The object of the invention is to provide a form for the manufacture shoes, which allows all operations to be carried out necessary, especially in the context of task automation, allowing the heating or maintaining at a determined temperature of the shape and as a result of the rod, during the transfer of the latter between two stations, or at certain work stations.

A cet effet, la forme qu'elle concerne, du type comprenant une zone de préhension constituée par deux plots tubulaires et présentant des évidements annulaires, permettant d'une part leur engagement sur deux tiges verticales appartenant à une palette, en vue du déplacement de la forme d'un poste à un autre, et d'autre part la préhension de la forme à l'aide de la mâchoire d'un organe préhenseur, est caractérisée en ce que la forme, réalisée en matière synthétique, contient une partie métallique équipée d'une résistance de chauffage, dont l'alimentation est réalisée à partir de deux fils conducteurs reliés aux deux plots métalliques de préhension qui sont eux-mêmes électriquement conducteurs et sont susceptibles d'être reliés aux deux bornes d'une source d'alimentation électrique. To this end, the form which it relates to, of the type comprising a gripping area consisting of two tubular studs and having annular recesses, allowing on the one hand their engagement on two vertical rods belonging to a pallet, for the purpose of moving the form from one post to another, and on the other hand gripping the form using of the jaw of a gripping organ, is characterized in that the shape, made of synthetic material, contains a metal part fitted a heating resistor, which is supplied from two conductive wires connected to the two metal gripping pads which are themselves electrically conductive and are likely to be connected to the two terminals of an electrical power source.

Dans une telle forme, les plots de montage de la forme sur une palette, ou de préhension de la forme et de maintien de celle-ci aux différents postes de travail, sont mis à profit pour réaliser l'alimentation électrique d'une résistance de chauffage incorporée.In such a form, the mounting pads of the form on a palette, or gripping the shape and holding it to different workstations are used to supply food electric heating resistor incorporated.

Suivant un mode d'exécution de cette forme, la partie métallique de la forme constitue la semelle de celle-ci.According to an embodiment of this form, the part metallic shape forms the sole thereof.

Suivant une autre caractéristique de l'invention chaque plot tubulaire est prolongé à rintérieur de la forme par une tige métallique conductrice reliée à la résistance de chauffage, directement ou par des fils conducteurs.According to another characteristic of the invention, each stud tubular is extended inside the form by a metal rod conductive connected to the heating resistor, directly or by wires conductors.

Si les plots tubulaires ou les tiges métalliques qui les prolongent traversent une embase métallique pouvant, par exemple, servir de support à une puce électronique mémorisant les opérations effectuées sur la tige montée sur cette forme, ainsi que les opérations futures que doit subir la tige, la traversée de cette embase métallique est réalisée avec interposition d'éléments isolants.If the tubular studs or the metal rods which extend them pass through a metal base that can, for example, serve as a support to an electronic chip memorizing the operations carried out on the rod rise on this form, as well as the future operations that must undergo the rod, the crossing of this metal base is made with interposition insulating elements.

Avantageusement, cette forme contient un thermostat agissant sur l'alimentation électrique de la résistance de chauffage. Le thermostat peut contrôler la température de la forme, et adapter celle-ci au type de travail à effectuer sur une tige, au fur et à mesure de l'avancement de la réalisation de celle-ci.Advantageously, this form contains an acting thermostat on the power supply of the heating resistor. The thermostat can control the temperature of the shape, and adapt it to the type of work to be done on a rod, as the advancement of the realization of it.

Selon une caractéristique de l'invention, chaque palette de transport comprend deux tiges de support de la forme, réalisées en métal conducteur et reliées aux deux bornes d'une source d'alimentation électrique par des fils conducteurs, montés sur la palette et venant en contact par l'intermédiaire de trolleys ou de frotteurs avec des pistes conductrices, fixés sur un rail appartenant au bâti support de guidage des palettes. Il est ainsi possible de maintenir une tige en température lors de son transfert entr deux postes, ou de réaliser son préchauffage afin de raccourcir le temps d'exécution d'une opération à un poste suivant.According to a characteristic of the invention, each palette of transport includes two support rods of the form, made of metal conductor and connected to the two terminals of an electrical power source by conducting wires, mounted on the pallet and coming into contact by via trolleys or wipers with conductive tracks, fixed on a rail belonging to the pallet guide support frame. It is so possible to maintain a rod in temperature during its transfer between two stations, or to preheat it to shorten the time execution of an operation at a next station.

Selon une autre caractéristique de l'invention, à certains postes de travail, chaque pince de préhension d'une forme comprend deux mâchoires réalisées en métal conducteur reliées aux deux bornes d'une source d'alimentation électrique et destinées chacune à enserrer l'un des plots de la forme. According to another characteristic of the invention, at certain stations working, each gripper of a shape includes two jaws made of conductive metal connected to the two terminals of a electrical power source and each intended to enclose one of the studs of the form.

Un poste de travail nécessitant un chauffage de la forme est par exemple un poste où s'effectue une opération de moulage.A workstation requiring heating of the form is by example a station where a molding operation takes place.

De toute façon l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cette forme.In any case, the invention will be well understood using the description which follows, with reference to the attached schematic drawing representing, by way of nonlimiting example, an embodiment of this shape.

Figure 1 est une vue en perspective, partiellement arrachée et coupée de cette forme, disposée au-dessus d'une palette de transport.Figure 1 is a perspective view, partially broken away and cut of this shape, placed above a transport pallet.

Figure 2 est une vue en coupe de cette même forme, en position montée sur la palette de transport.Figure 2 is a sectional view of the same shape, in position mounted on the transport pallet.

Figure 3 est une vue en perspective de cette forme en position de blocage entre les mâchoires d'un poste de travail.Figure 3 is a perspective view of this shape in position between the jaws of a work station.

La forme selon l'invention comporte un corps 2 en matière synthétique, équipé d'une semelle métallique 3 incorporant une résistance électrique 4. Le corps de la forme est équipé d'une embase 5 contenant, par exemple, une puce 6 destinée, dans le cadre d'une production automatisée de chaussures, à commander les différentes opérations devant être effectuées, et à mémoriser les opérations déjà effectuées. Cette forme est équipée de deux plots tubulaires cylindriques 7 parallèles l'un à l'autre, comportant chacun, débouchant dans sa périphérie, deux évidements annulaires 8. Les plots cylindriques sont réalisés dans un métal conducteur, et sont prolongés du côté de la forme par deux tiges 9 également en métal conducteur, qui traversent l'embase 5 avec interposition d'un matériau isolant électrique 10. Les tiges 9 sont reliées à la résistance électrique 4 par des fils conducteurs 12, avec montage, à l'intérieur de la forme, d'un thermostat de contrôle de température, non représenté au dessin.The form according to the invention comprises a body 2 made of material synthetic, fitted with a metallic sole 3 incorporating resistance electric 4. The body of the form is equipped with a base 5 containing, for example, a chip 6 intended, within the framework of a production automated shoes, to control the different operations in front be performed, and to memorize the operations already performed. This shape is equipped with two cylindrical tubular studs 7 parallel to each other, each comprising two openings in its periphery annular 8. The cylindrical pads are made of a conductive metal, and are extended on the form side by two rods 9 also made of metal conductor, which cross the base 5 with the interposition of a material electrical insulator 10. The rods 9 are connected to the electrical resistance 4 by conducting wires 12, with mounting, inside the form, of a temperature control thermostat, not shown in the drawing.

Il est donc ainsi établi que si les plots cylindriques 7 sont reliés aux deux bornes d'une source d'alimentation électrique, la résistance 4 est alimentée et chauffe la semelle métallique 3.It is thus thus established that if the cylindrical pads 7 are connected at the two terminals of an electrical power source, the resistor 4 is powered and heats the metal soleplate 3.

Les figures 1 et 2 représentent une palette de transport 13 d'une forme, destinée à reposer sur un bâti 14 sur lequel elle est déplacée par des moyens connus, et guidée par des galets 15. La forme 2 est destinée à être positionnée sur cette palette par engagement des deux plots 7 sur deux tiges 16 faisant saillie de la face supérieure de la palette. Ces deux tiges 16 sont réalisées en un métal conducteur, et sont reliées chacune par un fil 17 à un trolley ou frotteur 18 prenant appui contre une piste conductrice 19 reliée à une source d'alimentation de courant, solidaire du bâti 14. Il doit être noté que les pistes conductrices 19 sont montées sur le bâti 14 avec interposition d'un matériau 20 isolant électrique.Figures 1 and 2 show a transport pallet 13 of a shape, intended to rest on a frame 14 on which it is moved by known means, and guided by rollers 15. The shape 2 is intended to be positioned on this pallet by engagement of the two studs 7 on two rods 16 projecting from the upper face of the pallet. These two rods 16 are made of a conductive metal, and are connected each by a wire 17 to a trolley or wiper 18 bearing against a conductive track 19 connected to a current supply source, integral of the frame 14. It should be noted that the conductive tracks 19 are mounted on the frame 14 with the interposition of an electrically insulating material 20.

La figure 3 représente un dispositif de préhension de la forme 2 à un poste de travail. Ce dispositif de préhension comporte deux mâchoires 22 destinées à venir enserrer les plots cylindriques 7 au niveau de l'un des évidements circulaires 8. Les mâchoires 22, montées déplaçables sur un support 23, et avec interposition d'un matériau isolant non représenté, sont reliées aux bornes d'alimentation d'une source de courant.Figure 3 shows a form 2 gripping device at a work station. This gripping device has two jaws 22 intended to grip the cylindrical studs 7 at one of the circular recesses 8. The jaws 22, mounted displaceable on a support 23, and with the interposition of an insulating material not shown, are connected to the power supply terminals of a current source.

Ainsi, il est possible de réaliser le chauffage de la forme à la température souhaitée, tant lors du transport de celle-ci entre deux postes, par l'intermédiaire de la palette de transport 13, qu'au niveau même d'un poste, par l'intermédiaire des mâchoires 22 assurant la tenue des plots cylindriques de la forme.Thus, it is possible to heat the form to the desired temperature, both when transporting it between two stations, by means of the transport pallet 13, only at the level of a post, via the jaws 22 ensuring the holding of the studs cylindrical in shape.

Comme il ressort de ce qui précède l'invention apporte une grande amélioration à la technique existante, en fournissant une forme sur laquelle toutes les opérations relatives à la fabrication d'une chaussure peuvent être réalisées, sans nécessiter comme tel était le cas auparavant le transfert de la tige d'une forme en matière synthétique non chauffante sur une forme chauffante, et inversement, lorsque la fabrication de la chaussure nécessite certaines opérations de chauffage.As is apparent from the above, the invention provides a great improvement to the existing technique, providing a form on which all operations relating to the manufacture of a shoe can be performed, without requiring as was previously the case transfer of the rod from a non-heating plastic form to a heating form, and vice versa, when the manufacture of the shoe requires certain heating operations.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cette forme pour la fabrication de chaussures, décrite ci-dessus à titre d'exemple, et en embrasse au contraire toutes les variantes. C'est ainsi notamment que les moyens d'alimentation des plots cylindriques de la forme pourraient être différents ou encore que la résistance chauffante pourrait être logée non pas dans une plaque formant semelle de la forme, mais dans un insert de celle-ci, sans que l'on sorte pour autant du cadre de l'invention.It goes without saying that the invention is not limited to the single form of execution of this form for the manufacture of shoes, described above by way of example, and on the contrary embraces all variants thereof. In particular, this is how the means for feeding the cylindrical studs of the shape could be different or that the resistance heater could be housed not in a plate forming the sole of the shape, but in an insert of it, without leaving the part of the invention.
