Description
La présente invention a trait au domaine des appareils pour la fabrication de chaussures et concerne plus spécialement une adaption particulière, pour la réalisation de contreforts de grande longueur, de machines à double poste, c'est à dire travaillant par paire, destinées à réactiver les parties thermocollantes des éléments de chaussure à assembler puis à donner la forme définitive aux parties arrières de chaussures.The present invention relates to the field of apparatus for manufacturing shoes and more specifically relates to a particular adaptation, for the production of very long buttresses, of double-station machines, that is to say working in pairs, intended to reactivate the iron-on parts of the shoe elements to be assembled and then give the final shape to the rear parts of the shoes.
Dans les machines bien connues et préconisées jusqu'à présent pour la mise en forme de la partie arrière d'une chaussure, on effectue le galbage à l'aide d'un conformateur en introduisant l'arrière de la chaussure sur une forme (ou poinçon) métallique puis en mettant sous pression cette forme en contact avec l'élément incurvé, ou conformateur proprement dit. Bien souvent, la machine travaille par paire de chaussures et comprend généralement, sur le même bâti, en partie supérieure, deux postes de réactivation à chaud de la colle d'assemblage des éléments constitutifs de la chaussure et, en partie inférieure, le double poste conformateur/ poinçon destiné à effectuer la galbage et à le stabiliser à basse température.In machines which are well known and hitherto recommended for shaping the rear part of a shoe, the shaping is carried out using a shaping device by introducing the rear of the shoe onto a form (or punch) metallic then by pressurizing this shape in contact with the curved element, or actual shaper. Very often, the machine works by pair of shoes and generally comprises, on the same frame, in the upper part, two stations for hot reactivation of the adhesive for assembling the constituent elements of the shoe and, in the lower part, the double station conformator / punch intended for curving and stabilizing it at low temperature.
De telles machines conviennent bien pour la fabrication de chaussures courantes dans lesquelles les parties arrières ne présentent pas un galbe de grande longueur, comme par exemple les chaussures pour hommes. Toutefois, quand il s'agit de chaussures à contreforts longs, comme par exemple des chaussures à talons hauts pour femmes, les appareils précités ne peuvent travailler que sur la partie arrière du contrefort et n'assurent par le galbe qui se prolonge sur cette dernière. Afin d'obtenir ce galbe long, il faut soit recourir à des contreforts prégalbés obtenus par une fabrication préliminaire soit faire appel à des contreforts dits »chimiques« s'est à dire trempés dans un solvant pour les ramollir puis travaillés ensuite sur un poinçon en bois pour leur donner la forme nécessaire.Such machines are well suited for the manufacture of common shoes in which the rear parts do not have a long curve, such as for example men's shoes. However, when it comes to shoes with long buttresses, such as for example high-heeled shoes for women, the aforementioned devices can only work on the rear part of the buttress and do not provide by the curve which extends thereon. . In order to obtain this long curve, it is necessary either to use pre-curved buttresses obtained by a preliminary manufacture or to use so-called "chemical" buttresses, that is to say soaked in a solvent to soften them and then worked on a punch in wood to give them the necessary shape.
Ces opérations sont longues et fastidieuses et l'invention a précisément pour but de les supprimer en proposant une machine de principe général et fonctionnement connu en soi mais dans laquelle des adaption particulières ont été prévues pour pourvoir galber directement, en une seule opération sur la machine, les contreforts de grande longueur découpés à plat dans des plaques de matière synthétique thermocollante et insérés dans la tige de chaussure.These operations are long and tedious and the invention aims precisely to eliminate them by proposing a machine of general principle and operation known in itself but in which particular adaptations have been provided to provide for curving directly, in a single operation on the machine , the buttresses of great length cut flat in plates of thermobonding synthetic material and inserted in the shoe upper.
La nouvelle machine comporte conventionel- lement un poste double, à sa partie supérieure, pour la réactivation de la colle des éléments préassemblés de chaussure et, à sa partie inférieure, un second poste double conformateur/ poinçon destiné au galbage proprement dit. Selon les caractéristiques essentielles de l'invention, le poinçon métallique mis en oeuvre pour chacun des deux postes est galbé en grande longueur à la conformation du contrefort et, en outre, le conformateur du second poste est réalisé de façon telle que sa partie inférieure, que l'on dénommera selon l'usage »carre de forme«, ait une dureté nettement plus grande que celle de la partie supérieure.The new machine conventionally comprises a double station, at its upper part, for reactivating the glue of the preassembled shoe elements, and, at its lower part, a second double shaping station / punch intended for curving proper. According to the essential characteristics of the invention, the metal punch used for each of the two stations is curved in great length at the conformation of the buttress and, moreover, the conformator of the second station is produced in such a way that its lower part, which we will call according to use "square shape", has a hardness significantly greater than that of the upper part.
L'invention sera mieux comprise par une description plus détaillée d'un mode de réalisation non limitatif illustré par les dessins schématiques annexés qui représentent:The invention will be better understood from a more detailed description of a nonlimiting embodiment illustrated by the appended schematic drawings which represent:
- Figure 1: un type de machine conforme à l'invention,FIG. 1: a type of machine according to the invention,
- Figure 2: le détail d'un type de poinçon et d'un type de conformateur spécialement adapté à la machine de la figure 1.Figure 2: the detail of a type of punch and a type of shaper specially adapted to the machine of Figure 1.
Telle que représentée sur la figure 1, la machine de galbage des contreforts est de type et de fonctionnement automatique connus en soi et on notera essentiellement qu'elle est munie: sur la partie supérieure du bâti 1 d'un groupe de deux conformateurs (2, 3) avec leurs poinçons métalliques (4, 5) et, sur la table de travail proprement dite 6, d'un poste double de deux conformateurs (7, 8) avec leurs poinçons respectifs (9,10). Le poste double supérieur est destiné à la réactivation à chaud des contreforts en matière thermofusible et thermocollante, avec des conformateurs réalisés par exemple en deux couches dont l'une de base en résine silicone chargée à 30/40% en poids de poudre métallique (aluminium) et une couche superficielle en silicone pure. Le poste (7, 8) sur table de travail sert au galbage proprement dit, avec stabilisation du galbe pression pneumatique ou hydraulique température réfrigérée.As shown in FIG. 1, the buttress curving machine is of the type and of automatic operation known per se and it will essentially be noted that it is provided: on the upper part of the frame 1 with a group of two conformers (2 , 3) with their metal punches (4, 5) and, on the actual working table 6, of a double station of two conformers (7, 8) with their respective punches (9,10). The upper double station is intended for the hot reactivation of buttresses made of hot-melt and fusible material, with conformers made for example in two layers, one of which is made of silicone resin loaded with 30/40% by weight of metal powder (aluminum ) and a surface layer of pure silicone. The station (7, 8) on the work table is used for curving proper, with stabilization of the curve pneumatic or hydraulic pressure refrigerated temperature.
Selon les caractéristiques illustrées sur la figure 2, les poinçons utilisés (par exemple 4, 5 ou 9, 10) sont très allongés et revêtent la conformation exacte du contrefort. Par exemple, ils ont une longueur moyenne de 150 mm pour des contreforts de chaussures de dames à talons. Par alleurs, les conformateurs de galbage et stabilisation (7, 8) sont réalisés en une seule pièce de matière plastique (par exemple, résine silicone ou analogue) mais ils présentent la particularité de posséder deux indices de dureté nettement différents, par exemple de l'ordre de 50 à 70 shores pour la partie supérieure A et comprise dans la fouchette de 85 à 110 shores pour la base de jupe ou carre de forme B.According to the characteristics illustrated in FIG. 2, the punches used (for example 4, 5 or 9, 10) are very elongated and have the exact shape of the buttress. For example, they have an average length of 150 mm for the heels of ladies' heeled shoes. By goers, the shaping and stabilizing conformers (7, 8) are produced in a single piece of plastic material (for example, silicone resin or the like) but they have the particularity of having two distinctly different hardness indices, for example of the '' from 50 to 70 shores for the upper part A and included in the range of 85 to 110 shores for the base of the skirt or edge of form B.
En fonctionnement, on introduit dans la tige de la chaussure, avant mise en position de réactivation, directement les contreforts découpés à plat dans des plaques de matière synthétique thermocollante, sans effectuer d'opération préalable de prégalbage de ces contreforts longs. Dans la deuxième phase connue de serrage des contreforts dans les ensembles conformateurs (7, 8) poinçon (9, 10) à température réfrigérée, on obtient d'excellents résultats et nettement améliorés par rapport aux dispositifs de galbage connus jusqu'ici du fait que la carre très dure (B) des conformateurs assure une parfaite rigidité entre les éléments arrières de la chaussure alors que la partie supérieure plus souple (A) ne provoque aucun plissage lors de la pressurisation des éléments de la chaussure.In operation, the buttresses cut flat in sheets of thermo-adhesive synthetic material are introduced directly into the upper of the shoe, before being put into the reactivation position, without carrying out any prior operation for pre-cleaning these long buttresses. In the second known phase of tightening the buttresses in the shaping assemblies (7, 8) punch (9, 10) at refrigerated temperature, excellent results are obtained and markedly improved compared to the curving devices known up to now because the very hard edge (B) of the conformers ensures perfect rigidity between the rear elements of the shoe while the more flexible upper part (A) does not there is no wrinkling during the pressurization of the elements of the shoe.
