Definitions
- the present invention relates to a method for stacking several sheets of material having repeating patterns, while respecting the superimposition of the patterns from one sheet to another and device for its implementation.
- the cuts are repetitive and the same operations must be repeated with each new fold. If they are perfectly suited to the "tailor-made" cut for which the dimensions are never the same from one garment to another, they are, on the other hand, not very productive for small or medium series. It is therefore advantageous, in this case there, to cut several folds at the same time.
- the needles can be placed, in relation to a parent layout, or in relation to a standard "grid" close to that of the pattern. These needles are always placed before the first fold of fabric is deposited. The operator then deposits the folds, one by one, taking care, with each fold, to plant the needles, one by one, in the right places. The needles being fixed, it is necessary to stretch or contract the fabric to bring it to the desired position. The patterns, although repetitive, never have a perfectly constant pitch, which explains this permanent readjustment. Once the stacking is complete, the mattress thus formed is cut out, directly on the table, after the operator has taken care to remove the needles. This is the only procedure for obtaining a correct result. However, it is completely manual, long and tedious, impractical and is also incompatible with automatic cutting machines.
- the present invention overcomes these drawbacks for the first time and satisfactorily by proposing a method for stacking sheets of material having repeating patterns while respecting the superposition of said patterns from one sheet fold to the next, successively comprising: - depositing a relatively rigid sheet on a cutting table, - bringing and depositing from a supply member a first sheet fold with repetitive patterns on said relatively rigid sheet, - recording of an optimized arrangement of all the parts to be cut, - the installation of perforating vertical elements at predetermined points of said first ply to identify the patterns, - supplying, removing and fixing one by one of the following folds while respecting the superposition of the patterns by pressing said folds on the perforating elements already in place, characterized in that the feeding and removal of each fold takes place automatically - by engaging the free end of the fold in a clamp device mounted transversely on a main carriage movable longitudinally and on which is hung in its rear part a light conveyor belt, - then moving said carriage to the front of the cutting table, which has the effect
- the vertical perforating elements consist of needles which are intended to be removed after stacking the plies and before cutting the pieces and after each fold removal.
- self-adhesive pads are threaded onto the needles intended to fix the folds between them.
- the positioning of the perforating elements is carried out after each ply removal, said perforating elements being intended to fit into one another to fix the pleats between them and the perforating elements preferably being pushpins with a self-adhesive head made of a material which is sufficiently fragile not to hinder cutting.
- Another object of the invention is a device for stacking sheets of material having repeating patterns while respecting the superposition of said patterns from one sheet fold to the next, comprising a main carriage movable longitudinally relative to the cutting table and a light conveyor belt whose width is at least equal to that of the folds, characterized in that said carriage consists of two separable movable members, one of which is motorized and carries a shooting device used for recording the optimized arrangement of all the parts to be cut, and the other is towed and comprises a transverse clamp device intended to engage the free end of the folds, said towed member being hooked in its rear part to said light conveyor belt intended for support and protect the patterned sheet fold when fed.
- the light conveyor belt is kept under tension by two belts moving longitudinally on either side of the table passing over idler rollers located at the ends of said table and the belts are attached to the towed member of the main carriage and move with it, driving the free end of the light conveyor belt which supports the fold to be deposited.
- the towed member of the main carriage further comprises a cutting means intended to separate the successive folds from the supply member after their removal, said cutting means moving transversely relative to the towed member and the separable members of the main carriage being assembled by means of a device '' electromechanical attachment.
- the present invention therefore provides a method and a device for making stacks of sheets of material with repeating patterns, while respecting the superposition of patterns from one sheet to another, to prepare the cutting plane as a function of the distribution exact patterns and save material.
- the general chassis of the device is constituted by a table, resting on the ground by means of feet and whose tray (1) is covered by a thick carpet (2 ) made of rubber or similar.
- a mobile main carriage moves longitudinally relative to the table.
- This carriage consists of two separable movable members, one of which (3) is motorized and the other (6) of which is towed.
- the motorized member (3) carries a shooting device such as a camera (4). This camera is used for recording the arrangement of the patterns on the first fold. tissue.
- Servomotors provide controlled movements in speed and position of the motorized member (3) along the longitudinal axis and of the camera along the transverse axis.
- the camera (4) can therefore be moved at any point above the table.
- One of the additional advantages of having a camera is to be able to take into account possible faults. Indeed, when operators spread out the folds, if they notice the presence of a defect, they can move the camera above this defect and, by superimposing on the screen with the actual displacement, they can appreciate the importance of this defect: either it is outside the pieces and can be left, or it is on a piece and it is absolutely necessary to eliminate it, hence the exclusion of the part of fabric concerned according to traditional methods.
- the towed member (6) comprises a transverse clamp device (12) intended to engage the free end of the folds of tissue and on which is hung in its rear part a light conveyor belt (7), for example of the Mylar type, intended to support and protect the underside of the fold during its feeding.
- This light conveyor belt (7) is kept under tension by two belts (10) moving longitudinally on either side of the table passing over idler rollers (5) located at the ends of the table.
- the strip (7) is fixed at its free ends to the belts (10).
- the belts (10) are attached to the towed member (6) and move with it, driving the free end of the strip (7) which thus remains always taut and which supports the fold to be deposited.
- the towed member (6) also includes cutting means for separating the successive plies from the fabric supply member after they have been placed on the table.
- the supply member preferably consists of a roller (8), placed behind the table and which is capable of delivering tissue almost tension free.
- the axis of the roller (8) is motorized and receives start or stop orders via an optoelectronic cell (9).
- the fabric loop deliberately created between the fabric roll and the table allows automatic regulation of the fabric supply on the table. The tension of the fabric is at most equal to the weight of the loop.
- the fabric fold is therefore cut transversely by the cutting means which preferably consists of a rotary electric knife.
- This knife is carried by a secondary carriage which moves transversely on the towed member (6) and which is moved by an electric motor or a pneumatic cylinder.
- An automatic attachment device (15) makes it possible to assemble the motorized member (3) with the towed member (6).
- the towed member (6) is placed behind the motorized member (3) at a sufficient distance so that the operators can intervene on the fabric without being hampered.
- the towed member can be moved from one end of the table to the other to spread out a controlled length of fabric.
- a relatively rigid sheet such as a sheet of paper of the Kraft paper type or similar
- the different folds of fabric will be placed on this sheet. Its role is to serve as a rigid support for the future mattress in order to facilitate handling.
- the movable members (3, 6) are assembled by means of the hooking device to constitute the main movable carriage. The latter is brought into the rear position. The operators take the free end of the fabric (14), engage it in the clamp device (12) of the member (6) of the main carriage and lock the clamp to firmly hold the tissue.
- the main carriage is sent towards the front of the table, which has the effect of unrolling and stretching a certain length of fabric above the table by resting it on the light conveyor belt (7).
- the clamp (12) while maintaining manually or by mechanical means the free end of the fabric on the table then the main carriage is brought back, which results in depositing the fabric on the table.
- the main carriage is stopped at a certain predetermined distance and the fabric is cut across by means of the knife (13) of the member (6).
- the operator searches for the registered standard placement. This placement then appears on the screen. Superimposed and thanks to the camera, he sees the fabric and its patterns. It then has computer functions that allow you to readjust the placement piece precisely in relation to the pattern. Whenever necessary, the camera will be moved so as to reach the places outside the screen field.
- this interactive placement operation consists in superimposing several plies of fabric while ensuring the exact superimposition of the patterns relative to the first ply of fabric placed.
- vertical perforating elements (11) are used such as fine needles sharpened at their two ends which are stitched on the fabric at the places which are considered significant and which are predetermined.
- the operator performs this work according to his experience and the quantity of needles depends on the quality of superposition which he wishes to obtain.
- the upper face of the table is covered with a rubber-like mat (2) into which they can be inserted easily.
- the next fold is deposited.
- This removal will be carried out fold by fold from the start of the table to the rear.
- the operators placed on either side of the table, manipulate the fabric so as to stitch it on the vertical perforating elements in the same places as on the first fold.
- This operation will be repeated up to a length of fabric corresponding to the length of the placement that we want to perform.
- the depositing surface is no longer “smooth" and it is no longer possible to pull the fabric directly on this table, which will not fail to catch on the perforating elements (11) and thus deteriorate. It is to avoid this drawback that the strip of material of Mylar type or similar (7) is used, which one will choose for its lightness and its resistance to tearing.
- the belts (10) move at the same time as the main carriage on which they are hooked and drive the free end of the strip (7), which thus remains always taut.
- the position of the strip (7) is such that it passes above the ends of the perforating elements 11 when the latter are planted in the rubber mat (2).
- the strip (7) will slide over the ends of the perforating elements without deteriorating (hence the wise choice to make for the material of this sheet).
- the fabric, when it has been hooked by the clamp (12), thus rests on the continuous smooth surface which constitutes the strip (7).
- the mattress does not handle handling well, several solutions can be implemented in order to make the different folds inseparable from each other, with, however, the disadvantage of slightly lengthening the work cycle.
- the first solution is to use simple circular self-adhesive paper pads on both sides. Each time the fabric has been stitched on the needles, we add just at the point where the needle is a self-adhesive patch, which is threaded on the needle and glued by pressure on the fabric. When we come to put the next fold, there will be gluing of the two folds in this place. When the needles are removed, the different folds will be glued together. These pellets are made of a flexible material and if they happened to be on the passage of the blade during cutting, they would be cut without problem.
- the other solution is to use thumbtacks with a self-adhesive head and which have the ability to be able to fit into each other. As soon as the first fold of fabric has been applied, these pins are placed in the same way as the needles. They stay in place thanks to their self-adhesive head. When laying the following folds of fabric, we just fit a new pushpin on the one already in place and so on. This solution saves time since there is no need to remove the needles once all the folds of fabric have been placed. On the other hand, it is no longer necessary to use a rubber mat on the table. These pins are also made of a material that can be easily cut by the cutting blade in case they are in the passage of the latter.

Description
La présente invention concerne un procédé pour empiler plusieurs feuilles de matière ayant des motifs répétitifs, tout en respectant la superposition des motifs d'une feuille à l'autre et dispositif pour sa mise en oeuvre.The present invention relates to a method for stacking several sheets of material having repeating patterns, while respecting the superimposition of the patterns from one sheet to another and device for its implementation.
La fabrication d'articles constitués par la juxtaposition de plusieurs pièces découpées dans des feuilles de matériau comportant des motifs présente généralement quelques difficultés dès que l'on veut faire correspondre les motifs entre eux le long des lignes d'assemblage : c'est le cas, par exemple, en confection textile pour la fabrication de vêtements à partir de tissus à motifs répétitifs. D'autres domaines peuvent rencontrer les mêmes problèmes : industrie automobile (habillage des sièges de voiture), industrie de l'ameublement et de façon générale toutes les industries où l'on doit assembler des pièces de matières souples, telles que du tissu, tout en respectant le raccord correct des motifs).The manufacture of articles constituted by the juxtaposition of several pieces cut from sheets of material comprising patterns generally presents some difficulties as soon as one wants to match the patterns together along the assembly lines: this is the case , for example, in textile manufacturing for the manufacture of clothing from fabrics with repeating patterns. Other areas may encounter the same problems: automobile industry (car seat upholstery), furniture industry and generally all industries where parts of flexible materials, such as fabric, must be assembled respecting the correct connection of the patterns).
Ainsi par exemple dans la réalisation d'un vêtement taillé dans un tissu à motifs, en considérant que tous les patrons des différentes pièces ont été déterminés auparavant et que l'opérateur dispose des différents gabarits correspondants, la connaissance précise du modèle à obtenir, d'après les travaux des stylistes et modélistes, permet de déterminer les endroits précis où doivent se raccorder les motifs : c'est le cas d'une façon générale à tout endroit où l'on souhaite obtenir une continuité du motif tout en respectant la notion de volume. Ces endroits particuliers sont repérés sur les gabarits. L'opérateur étend alors un pli de tissu sur une table et commence à disposer ses gabarits directement sur ce pli en respectant la coïncidence des repères des gabarits et des motifs du tissu. Au bout du compte, il obtient un placement et peut découper les différentes pièces. Il assemblera par la suite les pièces entre elles jusqu'à obtenir le vêtement sous sa forme définitive. La procédure décrite ci-dessus, totalement manuelle, peut bien évidemment être avantageusement améliorée par des appareils connus et couramment utilisés permettant d'assurer la gradation automatique des patrons, la découpe automatique de ces patrons et la découpe automatique du tissu après enregistrement de la position des gabarits sur le tissu.Thus for example in the production of a garment cut from a patterned fabric, considering that all the patterns of the different pieces have been determined beforehand and that the operator has the different corresponding templates, precise knowledge of the model to be obtained, d '' after the work of stylists and model makers, allows to determine the precise places where the patterns must be connected: this is generally the case in any place where one wishes to obtain a continuity of the pattern while respecting the concept volume. These particular places are marked on the templates. The operator then spreads a fold of fabric on a table and begins to arrange his templates directly on this fold while respecting the coincidence of the marks of the templates and the patterns of the fabric. In the end, he gets a placement and can cut out the different pieces. He will then assemble the pieces together until he obtains the garment in its final form. The procedure described above, completely manual, can obviously be advantageously improved by devices known and commonly used to ensure the automatic gradation of the patterns, the automatic cutting of these patterns and the automatic cutting of the fabric after recording the position of the templates on the fabric.
Dans ce type de fabrication, les découpes sont répétitives et l'on doit refaire à chaque nouveau pli les mêmes opérations. Si elles sont parfaitement adaptées à la coupe "sur mesure" pour laquelle les dimensions ne sont jamais les mêmes d'un vêtement à un autre, elles sont, par contre, peu productives pour les petites ou moyennes séries. On a donc intérêt, dans ce cas là, à découper plusieurs plis en même temps. Il existe pour cela plusieurs techniques, toutes manuelles, utilisant des tables à aiguilles traditionnelles.L'opérateur doit superposer plusieurs plis de tissus tout en superposant précisément les motifs d'un pli à l'autre. Pour cela, on utilise des aiguilles matérialisant les points de raccord des motifs. Ces aiguilles sont disposées verticalement et directement sur la table de coupe. Suivant les méthodes de travail, les aiguilles peuvent être placées , par rapport à un tracé mère, ou par rapport à une "grille" standard proche de celle du motif. Ces aiguilles sont toujours placées avant que le premier pli de tissu ne soit déposé. L'opérateur dépose alors les plis, un à un, en prenant soin, à chaque pli, de planter les aiguilles, une à une, aux bons endroits. Les aiguilles étant fixes, il est nécessaire d'étirer ou de contracter le tissu pour l'amener à la position voulue. Les motifs, bien que répétitifs, n'ont jamais un pas de disposition parfaitement constant, ce qui explique ce réajustement permanent. Une fois l'empilage terminé, le matelas ainsi constitué est découpé, directement sur la table, après que l'opérateur a pris soin d'enlever les aiguilles. Cette procédure est la seule permettant d'obtenir un résultat correct. Elle est cependant totalement manuelle, longue et fastidieuse, peu pratique et est en outre incompatible avec les machines de coupe automatiques.In this type of manufacturing, the cuts are repetitive and the same operations must be repeated with each new fold. If they are perfectly suited to the "tailor-made" cut for which the dimensions are never the same from one garment to another, they are, on the other hand, not very productive for small or medium series. It is therefore advantageous, in this case there, to cut several folds at the same time. There are several techniques for this, all manual, using traditional needle tables. The operator must superimpose several folds of fabric while precisely superimposing the patterns from one fold to another. For this, needles are used materializing the points of connection of the patterns. These needles are arranged vertically and directly on the cutting table. Depending on the working methods, the needles can be placed, in relation to a parent layout, or in relation to a standard "grid" close to that of the pattern. These needles are always placed before the first fold of fabric is deposited. The operator then deposits the folds, one by one, taking care, with each fold, to plant the needles, one by one, in the right places. The needles being fixed, it is necessary to stretch or contract the fabric to bring it to the desired position. The patterns, although repetitive, never have a perfectly constant pitch, which explains this permanent readjustment. Once the stacking is complete, the mattress thus formed is cut out, directly on the table, after the operator has taken care to remove the needles. This is the only procedure for obtaining a correct result. However, it is completely manual, long and tedious, impractical and is also incompatible with automatic cutting machines.
La présente invention permet de remédier à ces inconvénients pour la première fois et de manière satisfaisante en proposant un procédé pour empiler avant leur découpe des feuilles de matière présentant des motifs répétitifs tout en respectant la superposition desdits motifs d'un pli de feuille au suivant, comprenant successivement :
- la dépose d'une feuille relativement rigide sur une table de découpe,
- l'amenée et la dépose à partir d'un organe d'approvisionnement d'un premier pli de feuille à motifs répétitifs sur ladite feuille relativement rigide,
- l'enregistrement d'un arrangement optimisé de toutes les pièces à découper,
- la mise en place d'éléments verticaux perforants à des points prédéterminés dudit premier pli pour repérer les motifs,
- l'amenée, la dépose et la fixation un par un des plis suivants en respectant la superposition des motifs par enfoncement desdits plis sur les éléments perforants déjà en place,
caractérisé en ce que l' amenée et la dépose de chaque pli s' effectuent de manière automatique
- en engageant l'extrémité libre du pli dans un dispositif de pince monté transversalement sur un chariot principal mobile longitudinalement et sur lequel est accrochée dans sa partie arrière une bande transporteuse légère,
- en déplaçant ensuite ledit chariot jusqu'à l'avant de la table de découpe, ce qui a pour effet d'étirer une certaine longueur de pli au-dessus de la table en le faisant reposer sur ladite bande transporteuse légère pour le protéger des éléments perforants,
- puis en libérant l'extrémité libre du pli du dispositif de pince tout en la maintenant sur la table,
- en ramenant, vers l'arrière de la table, le chariot avec la bande transporteuse légère,
et enfin en coupant transversalement le pli pour le séparer de l'organe d'approvisionnement.The present invention overcomes these drawbacks for the first time and satisfactorily by proposing a method for stacking sheets of material having repeating patterns while respecting the superposition of said patterns from one sheet fold to the next, successively comprising:
- depositing a relatively rigid sheet on a cutting table,
- bringing and depositing from a supply member a first sheet fold with repetitive patterns on said relatively rigid sheet,
- recording of an optimized arrangement of all the parts to be cut,
- the installation of perforating vertical elements at predetermined points of said first ply to identify the patterns,
- supplying, removing and fixing one by one of the following folds while respecting the superposition of the patterns by pressing said folds on the perforating elements already in place,
characterized in that the feeding and removal of each fold takes place automatically
- by engaging the free end of the fold in a clamp device mounted transversely on a main carriage movable longitudinally and on which is hung in its rear part a light conveyor belt,
- then moving said carriage to the front of the cutting table, which has the effect of stretching a certain length of fold above the table by making it rest on said light conveyor belt to protect it from perforating elements,
- then releasing the free end of the fold from the clamp device while keeping it on the table,
- by bringing the carriage with the light conveyor belt towards the rear of the table,
and finally by transversely cutting the fold to separate it from the supply member.
Selon un mode de mise en oeuvre du procédé de l'invention, les éléments perforants verticaux sont constitués d'aiguilles qui sont destinées à être enlevées après l'empilage des plis et avant la découpe des pièces et après chaque dépose de pli.According to an embodiment of the method of the invention, the vertical perforating elements consist of needles which are intended to be removed after stacking the plies and before cutting the pieces and after each fold removal.
Selon une variante de réalisation, on enfile sur les aiguilles des pastilles autocollantes destinées à fixer les plis entre eux.According to an alternative embodiment, self-adhesive pads are threaded onto the needles intended to fix the folds between them.
Selon une autre variante de mise en oeuvre du procédé de l'invention, la mise en place des éléments perforants s'effectue après chaque dépose de pli, lesdits éléments perforants étant destinés à s'emboîter les uns dans les autres pour fixer les plis entre eux et les éléments perforants étant de préférence des punaises à tête autocollante réalisées dans une matière suffisamment fragile pour ne pas gêner la découpe.According to another variant implementation of the method of the invention, the positioning of the perforating elements is carried out after each ply removal, said perforating elements being intended to fit into one another to fix the pleats between them and the perforating elements preferably being pushpins with a self-adhesive head made of a material which is sufficiently fragile not to hinder cutting.
Un autre objet de l'invention est un dispositif pour empiler des feuilles de matière présentant des motifs répétitifs tout en respectant la superposition desdits motifs d'un pli de feuille au suivant, comprenant un chariot principal mobile longitudinalement par rapport à la table de découpe et une bande transporteuse légère dont la largeur est au moins égale à celle des plis, caractérisé en ce que ledit chariot est constitué de deux organes mobiles séparables, dont l'un est motorisé et porte un dispositif de prise de vue utilisé pour l'enregistrement de l'arrangement optimisé de toutes les pièces à découper, et l'autre est tracté et comporte un dispositif de pince transversale destiné à engager l'extrémité libre des plis, ledit organe tracté étant accroché dans sa partie arrière à ladite bande transporteuse légère destinée à supporter et à protéger le pli de feuille à motifs lors de son amenée.Another object of the invention is a device for stacking sheets of material having repeating patterns while respecting the superposition of said patterns from one sheet fold to the next, comprising a main carriage movable longitudinally relative to the cutting table and a light conveyor belt whose width is at least equal to that of the folds, characterized in that said carriage consists of two separable movable members, one of which is motorized and carries a shooting device used for recording the optimized arrangement of all the parts to be cut, and the other is towed and comprises a transverse clamp device intended to engage the free end of the folds, said towed member being hooked in its rear part to said light conveyor belt intended for support and protect the patterned sheet fold when fed.
Selon un mode de réalisation de l'invention, la bande transporteuse légère est maintenue sous tension par deux courroies se déplaçant longitudinalement de part et d'autre de la table en passant sur des galets de renvoi situés aux extrémités de ladite table et les courroies sont accrochées à l'organe tracté du chariot principal et se déplacent avec lui en entraînant l'extrémité libre de la bande transporteuse légère qui supporte le pli à déposer.According to one embodiment of the invention, the light conveyor belt is kept under tension by two belts moving longitudinally on either side of the table passing over idler rollers located at the ends of said table and the belts are attached to the towed member of the main carriage and move with it, driving the free end of the light conveyor belt which supports the fold to be deposited.
Selon une autre caractéristique du dispositif de l'invenion, l'organe tracté du chariot principal comporte en outre un moyen de coupe destiné à séparer les plis successifs de l'organe d'approvisionnement après leur dépose, ledit moyen de coupe se déplaçant transversalement par rapport à l'organe tracté et les organes séparables du chariot principal étant assemblés au moyen d'un dispositif d'accrochage électromécanique.According to another characteristic of the device of the invention, the towed member of the main carriage further comprises a cutting means intended to separate the successive folds from the supply member after their removal, said cutting means moving transversely relative to the towed member and the separable members of the main carriage being assembled by means of a device '' electromechanical attachment.
La présente invention propose donc un procédé et un dispositif permettant de réaliser des empilages de feuilles de matière à motifs répétitifs, tout en respectant la superposition des motifs d'une feuille à l'autre, de préparer le plan de coupe en fonction de la répartition exacte des motifs et de faire des économies de matière.The present invention therefore provides a method and a device for making stacks of sheets of material with repeating patterns, while respecting the superposition of patterns from one sheet to another, to prepare the cutting plane as a function of the distribution exact patterns and save material.
De plus, l'automatisation des fonctions élémentaires améliore considérablement l'ergonomie du poste de travail. Bien que l'invention puisse être utilisée isolément, le maximum de ses capacités et de ses performances sera obtenu en association avec un système de découpe automatique.In addition, the automation of basic functions considerably improves the ergonomics of the workstation. Although the invention can be used in isolation, the maximum of its capacities and its performances will be obtained in association with an automatic cutting system.
L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins annexés, sur lesquels :
- - Les figures 1 et 2 représentent respectivement des vues générales latérale et supérieure du dispositif de l'invention.
- - la figure 3 représente le dispositif dans la phase initiale de l'amenée d'un pli de tissu à motifs ;
- - la figure 4 représente le dispositif dans la phase de dépose du même pli.
- - Figures 1 and 2 respectively show general side and top views of the device of the invention.
- - Figure 3 shows the device in the initial phase of supplying a fold of patterned fabric;
- - Figure 4 shows the device in the removal phase of the same fold.
Le châssis général du dispositif, tel qu'il est représenté sur les figures 1 et 2 , est constitué par une table, reposant sur le sol par l'intermédiaire de pieds et dont le plateau (1) est recouvert par un tapis épais (2) en caoutchouc ou similaire. Un chariot principal mobile se déplace longitudinalement par rapport à la table.The general chassis of the device, as shown in Figures 1 and 2, is constituted by a table, resting on the ground by means of feet and whose tray (1) is covered by a thick carpet (2 ) made of rubber or similar. A mobile main carriage moves longitudinally relative to the table.
Ce chariot est constitué de deux organes mobiles séparables dont l'un (3) est motorisé et dont l'autre (6) est tracté.This carriage consists of two separable movable members, one of which (3) is motorized and the other (6) of which is towed.
L'organe motorisé (3) porte un dispositif de prise de vue tel qu'une caméra (4) .Cette caméra est utilisée pour l'enregistrement de la disposition des motifs sur le premier pli de tissu.The motorized member (3) carries a shooting device such as a camera (4). This camera is used for recording the arrangement of the patterns on the first fold. tissue.
Des servomoteurs assurent les déplacements asservis en vitesse et en position de l'organe motorisé (3) selon l'axe longitudinal et de la caméra selon l'axe transversal.Servomotors provide controlled movements in speed and position of the motorized member (3) along the longitudinal axis and of the camera along the transverse axis.
Grâce à une commande numérique et un programme approprié, on peut donc déplacer la caméra (4) en tout point au-dessus de la table. Un des avantages supplémentaires de la présence d'une caméra est de pouvoir tenir compte d'éventuels défauts. En effet, lorsque les opérateurs étalent les plis, s'ils constatent la présence d'un défaut, ils peuvent déplacer la caméra au-dessus de ce défaut et, par surimpression à l'écran avec le déplacement réel, ils peuvent apprécier l'importance de ce défaut : soit il est en dehors des pièces et on peut le laisser, soit il est sur une pièce et il faut absolument l'éliminer d'où l'exclusion de la partie de tissu concerné suivant les méthodes traditionnelles.Thanks to a digital control and an appropriate program, the camera (4) can therefore be moved at any point above the table. One of the additional advantages of having a camera is to be able to take into account possible faults. Indeed, when operators spread out the folds, if they notice the presence of a defect, they can move the camera above this defect and, by superimposing on the screen with the actual displacement, they can appreciate the importance of this defect: either it is outside the pieces and can be left, or it is on a piece and it is absolutely necessary to eliminate it, hence the exclusion of the part of fabric concerned according to traditional methods.
L' organe tracté (6) comporte un dispositif de pince transversale (12) destiné à engager l'extrémité libre des plis de tissus et sur lequel est accroché dans sa partie arrière une bande transporteuse légère (7) , par exemple du type Mylar, destinée à supporter et à protéger la face inférieure du pli lors de son amenée.The towed member (6) comprises a transverse clamp device (12) intended to engage the free end of the folds of tissue and on which is hung in its rear part a light conveyor belt (7), for example of the Mylar type, intended to support and protect the underside of the fold during its feeding.
Cette bande transporteuse légère (7) est maintenue sous tension par deux courroies (10) se déplaçant longitudinalement de part et d'autre de la table en passant sur des galets de renvoi (5) situés aux extrémités de la table.This light conveyor belt (7) is kept under tension by two belts (10) moving longitudinally on either side of the table passing over idler rollers (5) located at the ends of the table.
La bande (7) est fixée au niveau de ses extrémités libres sur les courroies (10).The strip (7) is fixed at its free ends to the belts (10).
Les courroies (10) sont accrochées à l'organe tracté (6) et se déplacent avec lui en entraînant l'extrémité libre de la bande (7) qui reste ainsi toujours tendue et qui supporte le pli à déposer.The belts (10) are attached to the towed member (6) and move with it, driving the free end of the strip (7) which thus remains always taut and which supports the fold to be deposited.
L'organe tracté (6) comporte également un moyen de coupe destiné à séparer les plis successifs de l'organe d'approvisionnement en tissu après leur dépose sur la table. L'organe d'approvisionnement est constitué de préférence d'un rouleau (8), placé derrière la table et qui est capable de délivrer du tissu quasiment sans tension. L'axe du rouleau (8) est motorisé et reçoit des ordres de marche ou d'arrêt par l'intermédiaire d'une cellule optoélectronique (9). La boucle de tissu volontairement créée entre le rouleau de tissu et la table permet d'avoir une régulation automatique de l'approvisionnement en tissu sur la table. La tension du tissu est au plus égale au poids de la boucle.The towed member (6) also includes cutting means for separating the successive plies from the fabric supply member after they have been placed on the table. The supply member preferably consists of a roller (8), placed behind the table and which is capable of delivering tissue almost tension free. The axis of the roller (8) is motorized and receives start or stop orders via an optoelectronic cell (9). The fabric loop deliberately created between the fabric roll and the table allows automatic regulation of the fabric supply on the table. The tension of the fabric is at most equal to the weight of the loop.
Après la dépose, le pli de tissu est donc coupé transversalement par le moyen de coupe qui est de préférence constitué d'un couteau électrique rotatif. Ce couteau est porté par un chariot secondaire qui se déplace transversalement sur l'organe tracté (6) et qui est mû par un moteur électrique ou un vérin pneumatique.After removal, the fabric fold is therefore cut transversely by the cutting means which preferably consists of a rotary electric knife. This knife is carried by a secondary carriage which moves transversely on the towed member (6) and which is moved by an electric motor or a pneumatic cylinder.
Un dispositif d'accrochage automatique (15) permet d'assembler l'organe motorisé (3) avec l'organe tracté (6).An automatic attachment device (15) makes it possible to assemble the motorized member (3) with the towed member (6).
L'organe tracté (6) est placé derrière l'organe motorisé (3) à une distance suffisante pour que les opérateurs puissent intervenir sur le tissu sans être gênés.The towed member (6) is placed behind the motorized member (3) at a sufficient distance so that the operators can intervene on the fabric without being hampered.
Plusieurs solutions connues sont utilisables pour réaliser le dispositif (15), par des moyens électromécaniques, par électroaimant ou par vérin pneumatique.Several known solutions can be used to make the device (15), by electromechanical means, by electromagnet or by pneumatic cylinder.
Grâce à cet assemblage, l'organe tracté peut être déplacé d'un bout à l'autre de la table pour étaler une longueur contrôlée de tissu.Thanks to this assembly, the towed member can be moved from one end of the table to the other to spread out a controlled length of fabric.
Les figures 2 et 3 permettent de mieux comprendre le déroulement du procédé de l'invention.Figures 2 and 3 provide a better understanding of the process of the invention.
On commence par étaler, manuellement, une feuille relativement rigide, comme par exemple une feuille de papier du type papier Kraft ou similaire, sur la table. Les différents plis de tissu seront posés sur cette feuille. Son rôle est de servir de support rigide au futur matelas afin de faciliter les manutentions. On procède ensuite à l'étalement d'un premier pli de tissu. Les organes mobiles (3, 6) sont assemblés au moyen du dispositif d'accrochage pour constituer le chariot mobile principal. Ce dernier est amené en position arrière. Les opérateurs prennent l'extrémité libre du tissu (14), l'engagent dans le dispositif de pince (12) de l'organe (6) du chariot principal et verrouillent la pince pour maintenir fermement le tissu. Le chariot principal est envoyé vers l'avant de la table, ce qui a pour effet de dérouler et d'étirer une certaine longueur de tissu au-dessus de la table en le faisant reposer sur la bande transporteuse légère (7).0n libère la pince (12) tout en maintenant manuellement ou par des moyens mécaniques l'extrémité libre du tissu sur la table puis on ramène le chariot principal vers l'arrière, ce qui a pour résultat de déposer le tissu sur la table. On arrête le chariot principal à une certaine distance prédéterminée et on effectue la coupe transversale du tissu au moyen du couteau (13) de l'organe (6).We start by spreading, manually, a relatively rigid sheet, such as a sheet of paper of the Kraft paper type or similar, on the table. The different folds of fabric will be placed on this sheet. Its role is to serve as a rigid support for the future mattress in order to facilitate handling. We then proceed to the spreading of a first ply of fabric. The movable members (3, 6) are assembled by means of the hooking device to constitute the main movable carriage. The latter is brought into the rear position. The operators take the free end of the fabric (14), engage it in the clamp device (12) of the member (6) of the main carriage and lock the clamp to firmly hold the tissue. The main carriage is sent towards the front of the table, which has the effect of unrolling and stretching a certain length of fabric above the table by resting it on the light conveyor belt (7). the clamp (12) while maintaining manually or by mechanical means the free end of the fabric on the table then the main carriage is brought back, which results in depositing the fabric on the table. The main carriage is stopped at a certain predetermined distance and the fabric is cut across by means of the knife (13) of the member (6).
Une fois ce premier pli de tissu étalé, et, dans la mesure où l'on dispose en aval d'une machine de coupe automatique, on procède à l'opération dite de placement interactif. On appelle communément placement l'arrangement optimisé de toutes les pièces constituant le vêtement dans le but d'économiser de la matière. Ce placement est interactif quand l'opérateur choisit la disposition des pièces. Il peut aussi être totalement automatique, le calculateur se chargeant alors de trouver le meilleur arrangement possible. Pour cela, on utilise des moyens informatiques, à base de calculateurs et d'écrans de visualisation. Avant de procéder à cette opération, un travail de préparation est nécessaire. Un placement, dit de base, aura été préparé. Ce placement, optimisé, est caractérisé par un espacement minimum entre pièces correspondant à la moitié de la valeur théorique du pas du motif présent sur le tissu. On est ainsi sûr de pouvoir découper toutes les pièces, avec leurs points de raccord, dans le coupon de tissu ainsi déterminé.Once this first ply of fabric has been spread out, and, insofar as an automatic cutting machine is available downstream, the operation known as interactive placement is carried out. The optimized arrangement of all the pieces making up the garment is commonly called placement in order to save material. This placement is interactive when the operator chooses the layout of the rooms. It can also be fully automatic, the computer then taking care of finding the best possible arrangement. For this, computer means are used, based on computers and display screens. Before proceeding with this operation, preparatory work is necessary. A so-called basic placement will have been prepared. This optimized placement is characterized by a minimum spacing between pieces corresponding to half the theoretical value of the pitch of the pattern present on the fabric. We are thus sure to be able to cut all the pieces, with their connection points, in the fabric coupon thus determined.
L'opérateur recherche le placement type enregistré. Ce placement apparaît alors sur l'écran. En surimpression et grâce à la caméra, il voit le tissu et ses motifs. Il dispose alors de fonctions informatiques permettant de recaler la pièce du placement précisément par rapport au motif. Chaque fois que ce sera nécessaire, la caméra sera déplacée de façon à atteindre les endroits sortant du champ de l'écran.The operator searches for the registered standard placement. This placement then appears on the screen. Superimposed and thanks to the camera, he sees the fabric and its patterns. It then has computer functions that allow you to readjust the placement piece precisely in relation to the pattern. Whenever necessary, the camera will be moved so as to reach the places outside the screen field.
On procède ainsi pièce par pièce de façon à réajuster toutes les pièces du placement d'origine. On crée alors un nouveau placement correspondant précisément au pli de tissu déposé, lequel est mis en mémoire pour l'opération de coupe. Cette procédure, semi-automatique, peut être totalement automatisée. A ce moment là, c'est le calculateur qui se charge de calculer les déplacements des pièces du placement origine de façon à les faire correspondre avec les motifs.This is done piece by piece so as to readjust all the pieces of the original placement. We then create a new placement corresponding precisely to the fold of fabric deposited, which is stored in memory for the cutting operation. This semi-automatic procedure can be fully automated. At that time, it is the computer which is responsible for calculating the displacements of the pieces of the original placement so as to match them with the patterns.
Que l'on procède ou non à cette opération de placement interactif, l'opération suivante consiste à superposer plusieurs plis de tissu en assurant la superposition exacte des motifs relativement au premier pli de tissu posé. Pour cela, on utilise des éléments verticaux perforants (11) tels que de fines aiguilles affûtées à leurs deux extrémités que l'on vient piquer sur le tissu aux endroits que l'on estime significatifs et qui sont prédéterminés. L'opérateur effectue ce travail selon son expérience et la quantité d'aiguilles dépend de la qualité de superposition qu'il souhaite obtenir. Afin de rendre possible la mise en place des aiguilles, la face supérieure de la table est recouverte d'un tapis (2) de type caoutchouteux dans lequel on pourra les enfoncer facilement.Whether or not this interactive placement operation is carried out, the following operation consists in superimposing several plies of fabric while ensuring the exact superimposition of the patterns relative to the first ply of fabric placed. For this, vertical perforating elements (11) are used such as fine needles sharpened at their two ends which are stitched on the fabric at the places which are considered significant and which are predetermined. The operator performs this work according to his experience and the quantity of needles depends on the quality of superposition which he wishes to obtain. In order to make it possible to place the needles, the upper face of the table is covered with a rubber-like mat (2) into which they can be inserted easily.
Une fois tous les éléments perforants(11) positionnés, on dépose le pli suivant. Cette dépose sera effectuée pli par pli depuis le début de la table jusque vers la partie arrière. A chaque dépose, les opérateurs, disposés de part et d'autre de la table, manipulent le tissu de façon à le piquer sur les éléments perforants verticaux aux mêmes endroits que sur le premier pli. Cette opération sera répétée jusqu'à une longueur de tissu correspondant à la longueur du placement que l'on veut effectuer. Mais, la surface de dépose n'est plus "lisse" et on ne peut plus tirer du tissu directement sur cette table, lequel ne manquerait pas de s'accrocher sur les éléments perforants (11) et ainsi se détériorerait. C'est pour éviter cet inconvénient que l'on utilise la bande de matière de type Mylar ou similaire (7), que l'on choisira pour sa légèreté et sa résistance au déchirement. Les courroies (10) se déplacent en même temps que le chariot principal sur lequel elles sont accrochées et entraînent l'extrémité libre de la bande (7), laquelle reste ainsi toujours tendue. La position de la bande (7) est telle qu'elle passe au-dessus des extrémités des éléments perforants 11 lorsque ces derniers sont plantés dans le tapis en caoutchouc (2) . Lors des déplacements du chariot principal, la bande (7) glissera sur les extrémités des éléments perforants sans se détériorer (d'où le choix judicieux à faire pour la matière de cette feuille). Le tissu, lorsqu'il a été accroché par la pince (12), repose ainsi sur la surface lisse continue que constitue la bande (7). Dans le cas où un placement interactif aura été créé à partir des motifs réels, la connaissance précise de la longueur du matelas, déterminée par le calculateur, permettra de couper les différents plis à une longueur optimale d'où un gain de matière par rapport à la méthode conventionnelle. Lorsque le matelas est terminé, les opérateurs enlèvent les éléments perforants et transfèrent manuellement le matelas vers la table de coupe en le faisant glisser en prenant soin de tirer uniquement sur la feuille inférieure en papier ou similaire. Ceci est important afin d'éviter de déplacer les plis entre eux, ce qui détruirait la superposition des motifs.Once all the perforating elements (11) positioned, the next fold is deposited. This removal will be carried out fold by fold from the start of the table to the rear. At each removal, the operators, placed on either side of the table, manipulate the fabric so as to stitch it on the vertical perforating elements in the same places as on the first fold. This operation will be repeated up to a length of fabric corresponding to the length of the placement that we want to perform. However, the depositing surface is no longer "smooth" and it is no longer possible to pull the fabric directly on this table, which will not fail to catch on the perforating elements (11) and thus deteriorate. It is to avoid this drawback that the strip of material of Mylar type or similar (7) is used, which one will choose for its lightness and its resistance to tearing. The belts (10) move at the same time as the main carriage on which they are hooked and drive the free end of the strip (7), which thus remains always taut. The position of the strip (7) is such that it passes above the ends of the perforating
Si le matelas supporte mal les manutentions, plusieurs solutions peuvent être mises en oeuvre afin de rendre indissociables les différents plis entre eux, avec malgré tout le désavantage d'allonger légèrement le cycle de travail. La première solution consiste à utiliser de simples pastilles circulaires en papier autocollant sur les deux faces. Chaque fois que le tissu aura été piqué sur les aiguilles, on vient rajouter juste à l'endroit où se trouve l'aiguille une pastille autocollante, laquelle est enfilée sur l'aiguille et collée par pression sur le tissu. Lorsqu'on viendra mettre le pli suivant, il y aura collage des deux plis à cet endroit. Lorsque l'on ôtera les aiguilles, les différents plis seront collés entre eux. Ces pastilles sont réalisées en un matériau souple et si elles se trouvaient par hasard sur le passage de la lame lors de la coupe, elles seraient coupées sans problème.If the mattress does not handle handling well, several solutions can be implemented in order to make the different folds inseparable from each other, with, however, the disadvantage of slightly lengthening the work cycle. The first solution is to use simple circular self-adhesive paper pads on both sides. Each time the fabric has been stitched on the needles, we add just at the point where the needle is a self-adhesive patch, which is threaded on the needle and glued by pressure on the fabric. When we come to put the next fold, there will be gluing of the two folds in this place. When the needles are removed, the different folds will be glued together. These pellets are made of a flexible material and if they happened to be on the passage of the blade during cutting, they would be cut without problem.
L'autre solution consiste à utiliser des punaises avec une tête autocollante et qui ont la faculté de pouvoir s'emboîter les unes dans les autres. Dès que le premier pli de tissu a été posé, on dispose ces punaises de la même façon que les aiguilles. Elles restent en place grâce à leur tête autocollante. Lors de la pose des plis de tissu suivants, on vient emboîter une nouvelle punaise sur celle déjà en place et ainsi de suite. Cette solution permet un gain de temps puisqu'il n'y a plus à ôter les aiguilles une fois tous les plis de tissu posés. D'autre part, il n'est plus nécessaire d'utiliser un tapis caoutchouteux sur la table. Ces punaises sont également réalisées dans une matière pouvant être coupée facilement par la lame de coupe au cas où elles se trouveraient sur le passage de cette dernière.The other solution is to use thumbtacks with a self-adhesive head and which have the ability to be able to fit into each other. As soon as the first fold of fabric has been applied, these pins are placed in the same way as the needles. They stay in place thanks to their self-adhesive head. When laying the following folds of fabric, we just fit a new pushpin on the one already in place and so on. This solution saves time since there is no need to remove the needles once all the folds of fabric have been placed. On the other hand, it is no longer necessary to use a rubber mat on the table. These pins are also made of a material that can be easily cut by the cutting blade in case they are in the passage of the latter.
