Description

L'invention concerne une machine automatique servant à traiter un matériau en bande tel qu'un matériau stratifié, un tissu ou tout autre matériau pouvant être stocké sous la forme d'un rouleau.The invention relates to an automatic machine for processing strip material such as laminate, fabric or any other material which can be stored in the form of a roll.

L'invention s'applique en particulier au cas où le traitement effectué sur une telle machine consiste en une découpe du matériau selon une ligne quelconque, par exemple au moyen d'un jet fluide sous haute pression. Cette application n'est cependant pas limitative et l'invention peut aussi être utilisée sur toute autre machine telle qu'une machine à draper, une machine à broder, etc.The invention applies in particular to the case where the treatment carried out on such a machine consists in cutting the material along any line, for example by means of a fluid jet under high pressure. This application is not, however, limiting and the invention can also be used on any other machine such as a draping machine, an embroidery machine, etc.

Dans la demande de brevet européen EP-A 145 527 qui correspond ou préambule de la revendication 1, on a décrit et revendiqué une machine de découpe de matière en bande par jet fluide haute pression. Dans cette machine, le rouleau de matériau est placé sur un réceptacle lié au bâti de la machine et la découpe est réalisée grâce aux déplacements combinés du matériau et de la buse de découpe, cette dernière se déplaçant selon une direction perpendiculaire à la direction de déplacement du matériau.In European patent application EP-A 145 527 which corresponds or preamble to claim 1, a machine for cutting strip material by high pressure fluid jet has been described and claimed. In this machine, the roll of material is placed on a receptacle linked to the frame of the machine and cutting is carried out thanks to the combined movements of the material and the cutting nozzle, the latter moving in a direction perpendicular to the direction of movement of the material.

Une telle machine, entièrement automatisée, fonctionne généralement de façon satisfaisante tant que le rouleau de matériau n'est pas épuisé. Cependant, lorsqu'on arrive à la fin du rouleau ou lorsque l'on désire changer de nature de matériau, il se produit une perte de temps importante consécutive au remplacement du rouleau de matériau. Compte tenu de la cadence très élevée d'une telle machine, cette perte de temps n'est évidemment pas satisfaisante.Such a fully automated machine generally works satisfactorily as long as the roll of material is not used up. However, when you reach the end of the roll or when you want to change the nature of the material, there is a significant loss of time following the replacement of the roll of material. Given the very high rate of such a machine, this loss of time is obviously not satisfactory.

Un problème identique existe sur les machines effectuant des traitements d'un autre type sur un matériau en bande.An identical problem exists on machines performing treatments of another type on a strip material.

La présente invention a précisément pour objet une machine automatique pour le traitement d'un matériau en bande, dans laquelle la perte de temps consécutive au remplacement du rouleau de matériau est réduite dans des proportions considérables, de sorte que la cadence de travail n'est pas trop affectée par ces remplacements.The object of the present invention is precisely an automatic machine for processing strip material, in which the loss of time following the replacement of the roll of material is reduced in considerable proportions, so that the rate of work is not not too affected by these replacements.

Selon un autre aspect de l'invention, le rouleau de matériau est monté sur un mandrin présentant une extrémité tubulaire, la machine comprenant de plus un châssis annexe lié au bâti et disposé sur le côté du module d'alimentation lorsque les moyens de raccordement et de positionnement sont connectés, ce châssis annexe portant un ensemble moteur incluant un embrayage pneumatique apte à être introduit dans l'extrémité tubulaire du mandrin sous l'action de moyens de translation par lesquels cet ensemble moteur est monté sur le châssis annexe.According to another aspect of the invention, the material roll is mounted on a mandrel having a tubular end, the machine further comprising an annex frame linked to the frame and disposed on the side of the supply module when the connection means and positioning are connected, this annex chassis carrying an engine assembly including a pneumatic clutch capable of being introduced into the tubular end of the mandrel under the action of translation means by which this engine assembly is mounted on the annex chassis.

Le châssis du module d'alimentation porte de préférence un rouleau transversal de tension du matériau, apte à être reçu dans une boucle du matériau formé entre le rouleau de matériau reçu sur le réceptacle et les moyens de pinçage, ce rouleau se déplaçant par gravité dans des guides verticaux formés dans le châssis du module d'alimentation, des détecteurs de fin de course haute et basse étant montés sur le châssis annexe.The chassis of the supply module preferably carries a transverse roller for tensioning the material, capable of being received in a loop of the material formed between the roller of material received on the receptacle and the clamping means, this roller moving by gravity in vertical guides formed in the chassis of the power supply module, upper and lower limit switches being mounted on the auxiliary chassis.

Selon un autre aspect de l'invention, le bâti de la machine porte, à proximité de son extrémité d'entrée, au moins un rouleau presseur d'axe légèrement incliné par rapport à une direction transversale à la direction de déplacement de la courroie, de façon appliquer sur le matériau un effort transversal dirigé vers un guide latéral porté par le bâti.According to another aspect of the invention, the frame of the machine carries, near its inlet end, at least one pressure roller with an axis slightly inclined with respect to a direction transverse to the direction of movement of the belt, so as to apply a transverse force on the material directed towards a lateral guide carried by the frame.

Dans une application particulière d'une telle machine à la découpe d'un matériau en bande, cette machine comprend un outil de découpe porté par un chariot mobile selon une direction transversale par rapport à la direction de déplacement de la courroie; des moyens de marquage du matériau peuvent également être supportés par le chariot mobile.In a particular application of such a machine for cutting a strip material, this machine comprises a cutting tool carried by a movable carriage in a direction transverse to the direction of movement of the belt; material marking means can also be supported by the mobile carriage.

De préférence, ces moyens de marquage comprennent une pince de préhension montée sur le chariot mobile par l'intermédiaire de moyens pour déplacer la pince entre une position haute et une position basse, un marqueur, et un capuchon porté par le bâti et dans lequel peut être emboîtée une extrémité active du marqueur, celui-ci comprenant de plus une zone de préhension apte à être emboîtée dans ladite pince.Preferably, these marking means comprise a gripping clamp mounted on the mobile carriage by means of means for moving the clamp between a high position and a low position, a marker, and a cap carried by the frame and in which can be fitted an active end of the marker, the latter further comprising a gripping area capable of being fitted into said clamp.

Le capuchon peut notamment être monté dans le bâti par l'intermédiaire de moyens pour déplacer ce capuchon entre une position basse escamotée et une position haute dans laquelle la zone de préhension est au niveau de la pince, lorsque cette dernière est en position basse.The cap can in particular be mounted in the frame by means of means for moving this cap between a low retracted position and a high position in which the gripping zone is at the level of the clamp, when the latter is in the low position.

Enfin, la pince peut comprendre deux mors articulés, maintenus normalement en position fermée par des moyens élastiques.Finally, the clamp may include two articulated jaws, normally maintained in the closed position by elastic means.

Sur les figures 1 et 2, on a représenté une machine de découpe par jet fluide haute pression réalisée conformément à l'invention. Cette machine comprend un bâti 10 représentant en vue de dessus une forme rectangulaire allongée, dont les petits côtés forment respectivement une extrémité d'entrée 10a et une extrémité de sortie 10b du matériau M à découper.In Figures 1 and 2, there is shown a cutting machine by high pressure fluid jet produced in accordance with the invention. This machine comprises a frame 10 representing in top view an elongated rectangular shape, the short sides of which respectively form an inlet end 10a and an outlet end 10b of the material M to be cut.

Le bâti 10 repose sur le sol et est divisé dans le sens de sa longueur en deux parties approximativement égales, supportant chacune une série de courroies transporteuses crantées et juxtaposées 12 et 14. Les courroies 12 sont tendues longitudinalement entre deux rouleaux transversaux 16 dont l'un est placé à l'extrémité d'entrée du bâti 10 et les courroies 14 sont tendues longitudinalement entre deux rouleaux transversaux 17 dont l'un est placé à l'extrémité de sortie 10b du bâti, les deux autres rouleaux 16 et 17 étant disposés côte à côte au centre de la machine.The frame 10 rests on the ground and is divided lengthwise into two approximately equal parts, each supporting a series of notched and juxtaposed conveyor belts 12 and 14. The belts 12 are stretched longitudinally between two transverse rollers 16, the one is placed at the inlet end of the frame 10 and the belts 14 are stretched longitudinally between two transverse rollers 17 one of which is placed at the outlet end 10b of the frame, the other two rollers 16 and 17 being arranged side by side in the center of the machine.

Les axes horizontaux des rouleaux 16 et 17 sont tous parallèles entre eux et disposés au même niveau sur le bâti 10, de telle sorte que les faces supérieures des courroies forment une table horizontale mobile apte à recevoir le matériau M à découper.The horizontal axes of the rollers 16 and 17 are all mutually parallel and disposed at the same level on the frame 10, so that the upper faces of the belts form a movable horizontal table capable of receiving the material M to be cut.

L'un des rouleaux 16 et 17 sur lesquels passe chacune des séries de courroies 12 et 14 est relié à un moteur d'entraînement (non représenté) apte à déplacer ces courroies dans l'un ou l'autre sens selon une direction longitudinale, comme l'indique la flèche Fi sur la figure 2. La commande de l'avance des deux séries de courroies crantées 12 et 14 est réalisée de façon synchrone.One of the rollers 16 and 17 over which each of the series of belts 12 and 14 passes is connected to a drive motor (not shown) capable of moving these belts in either direction in a longitudinal direction, as indicated by the arrow Fi in FIG. 2. The control of the advance of the two sets of toothed belts 12 and 14 is carried out synchronously.

Les courroies 12 et 14 permettent ainsi de déplacer le matériau en bande M devant un poste de découpe 18 situé dans la partie centrale de la machine, entre les deux séries de courroies 12 et 14.The belts 12 and 14 thus make it possible to move the strip material M in front of a cutting station 18 located in the central part of the machine, between the two sets of belts 12 and 14.

Ce poste de découpe 18 comprend tout d'abord une table horizontale fixe 20, de faible largeur, assurant le supportage du matériau à découper entre les extrémités adjacentes de séries de courroies crantées 12 et 14.This cutting station 18 firstly comprises a fixed horizontal table 20, of small width, ensuring the support of the material to be cut between the adjacent ends of series of toothed belts 12 and 14.

Le poste de découpe 18 comprend de plus un chariot mobile 22 apte à se déplacer sur des colonnes horizontales telles que 24 disposées transversalement, sous l'action de moyens de commande.The cutting station 18 further comprises a movable carriage 22 able to move on horizontal columns such as 24 arranged transversely, under the action of control means.

Ces moyens de commande comprennent par exemple une chaîne ou une courroie crantée 26 dont les extrémités sont fixées sur le chariot 22. Cette courroie 26 est tendue transversalement entre deux roues dentées 28 montées sur le bâti 10 et dont l'une est reliée à un moteur (non représenté) assurant son entraînement. Grâce à cet agencement, on peut déplacer le chariot 22 dans l'un ou l'autre sens selon une direction transversale, comme l'indique la flèche F2 sur la figure 2.These control means comprise for example a chain or a toothed belt 26, the ends of which are fixed on the carriage 22. This belt 26 is stretched transversely between two toothed wheels 28 mounted on the frame 10 and one of which is connected to a motor. (not shown) ensuring its training. Thanks to this arrangement, the carriage 22 can be moved in either direction in a transverse direction, as indicated by the arrow F 2 in FIG. 2.

De façon connue, le chariot 22 supporte une buse de découpe 30 située verticalement au-dessus de la table fixe 20. Cette buse 30 est raccordée à une installation d'alimentation en fluide sous haute pression, d'une manière en elle-même connue et non représentée sur la figure.In known manner, the carriage 22 supports a cutting nozzle 30 located vertically above the fixed table 20. This nozzle 30 is connected to a high pressure fluid supply installation, in a manner known per se and not shown in the figure.

Pour permettre la récupération du jet fluide émis par la buse 30, la table fixe 20 est percée sur toute la largeur du matériau M d'une fente transversale 20a sous laquelle est disposé un dispositif récupérateur de jet d'un quelconque type connu. Ce dispositif peut notamment être celui qui est décrit dans la demande de brevet français no83 16466 au nom de la Société Nationale Industrielle AEROSPATIALE.To allow the recovery of the fluid jet emitted by the nozzle 30, the fixed table 20 is pierced over the entire width of the material M with a transverse slot 20a under which is disposed a jet recovery device of any known type. This device may particularly be the one described in the French patent application No. 83 16466 in the name of Societe Nationale Industrielle Aerospatiale.

De préférence, le chariot 22 supporte également - une pince de préhension 32 apte à se saisir d'un marqueur pour effectuer un marquage préalable sur le matériau à découper. Cette pince 32 est montée sur le chariot 22 du côté opposé à la buse de découpe 30.Preferably, the carriage 22 also supports - a gripper 32 capable of gripping a marker to make a preliminary marking on the material to be cut. This clamp 32 is mounted on the carriage 22 on the side opposite to the cutting nozzle 30.

Comme l'illustrent plus précisément les figures 3 à 5, la pince 32 comprend un support 34 dont une extrémité est articulée sur le chariot 22 par un axe 36 orienté parallèlement à la direction de déplacement longitudinale Fi de la machine. A son extrémité opposée, le support 34 porte deux mors 38 articulés sur le support par deux axes 40 orientés selon une direction orthogonale par rapport l'axe 36, et approximativement verticale.As illustrated more precisely in FIGS. 3 to 5, the clamp 32 comprises a support 34, one end of which is articulated on the carriage 22 by an axis 36 oriented parallel to the direction of longitudinal movement F i of the machine. At its opposite end, the support 34 carries two jaws 38 articulated on the support by two axes 40 oriented in a direction orthogonal to the axis 36, and approximately vertical.

Un ressort 42, placé entre les mors 38, maintient ces derniers dans une position de serrage ou de préhension. Dans cette position, comme l'illustre notamment la figure 5, les surfaces de préhension 38a en vis-à-vis des mors 38 restent écartées l'une de l'autre. A leurs extrémités, ces surfaces 38a se terminent par un chanfrein permettant l'emboîtement automatique du marqueur, comme on le verra ultérieurement, les surfaces de préhension se prolongeant derrière ces chanfreins par des parties concaves présentant en vue de dessus la forme d'arcs de cercle.A spring 42, placed between the jaws 38, maintains the latter in a clamping or gripping position. In this position, as illustrated in particular in Figure 5, the gripping surfaces 38a vis-à-vis the jaws 38 remain spaced from one another. At their ends, these surfaces 38a end in a chamfer allowing the automatic nesting of the marker, as will be seen later, the gripping surfaces extending behind these chamfers by concave parts having a view from above in the form of arcs of circle.

En se reportant à la figure 4, on voit que dans sa zone médiane comprise entre son axe d'articulation 36 et les axes 40 portant les mors 38, le support 34 est interposé entre une butée inférieure 44 solidaire du chariot 22 et la tige verticale 46a d'un électroaimant 46 également portée par le chariot. Un ressort à lame 48 fixé sur la butée inférieure 44 maintient le support 34 en permanence en appui contre la tige 46a de l'électroaimant.Referring to FIG. 4, it can be seen that in its median zone comprised between its articulation axis 36 and the axes 40 carrying the jaws 38, the support 34 is interposed between a lower stop 44 secured to the carriage 22 and the vertical rod 46a of an electromagnet 46 also carried by the carriage. A leaf spring 48 fixed on the lower stop 44 maintains the support 34 permanently in abutment against the rod 46a of the electromagnet.

Grâce à cette configuration, la pince 32 peut occuper deux positions selon que l'électroaimant 46 est excité ou non.With this configuration, the clamp 32 can occupy two positions depending on whether the electromagnet 46 is energized or not.

Comme on l'a représenté en trait plein sur la figure 4, lors de l'excitation de l'électroaimant 46, la tige 46a applique le support 34 de la pince contre la butée inférieure 44. La pince 32 occupe alors une position basse de préhension sensiblement horizontale, dans laquelle les axes des parties en arc de cercle des surfaces de préhension 38a sont verticaux.As shown in solid lines in FIG. 4, during the excitation of the electromagnet 46, the rod 46a applies the support 34 of the clamp against the lower stop 44. The clamp 32 then occupies a low position of substantially horizontal gripping, in which the axes of the parts in an arc of the gripping surfaces 38a are vertical.

Au contraire, lorsque l'excitation de l'électroaimant 46 est interrompue, le ressort 48 fait pivoter le support 34 de la pince vers le haut autour de son axe 36 (flèche F3). La pince 32 occupe alors une position haute inclinée représentée en traits mixtes sur la figure 4, position permettant le transport du marqueur comme on le verra ultérieurement.On the contrary, when the excitation of the electromagnet 46 is interrupted, the spring 48 pivots the support 34 of the clamp upward about its axis 36 (arrow F 3 ). The clamp 32 then occupies an inclined high position shown in broken lines in FIG. 4, a position allowing the transport of the marker as will be seen later.

Pour compléter la pince 32, les moyens de marquage comprennent de plus un marqueur 50 dont l'extrémité inférieure active 50a portant la pointe 50b est reçue dans un capuchon 52, d'axe vertical, lorsqu'il n'est pas utilisé.To complete the clamp 32, the marking means further comprise a marker 50 whose active lower end 50a carrying the tip 50b is received in a cap 52, of vertical axis, when it is not used.

Ce capuchon 52 est monté dans le bâti 10 de la machine, dans un évidement cylindrique d'axe vertical 54 débouchant sur le côté de la série de courroies 12 vers lequel est tournée la pince 32, l'axe de cet évidement 54 étant situé dans le plan vertical médian de la pince 32.This cap 52 is mounted in the frame 10 of the machine, in a cylindrical recess with a vertical axis 54 opening onto the side of the series of belts 12 towards which the clamp 32 is turned, the axis of this recess 54 being located in the vertical median plane of the clamp 32.

A l'intérieur du bâti 10, des moyens sont prévus pour déplacer le capuchon 52 entre une position basse dans laquelle le marqueur 50 est escamoté et une position haute permettant la préhension de ce marqueur par la pince 32 (flèche F4). Dans le mode de réalisation représenté sur la figure 3, le mouvement de translation F4 est obtenu par vérin pneumatique.Inside the frame 10, means are provided for moving the cap 52 between a low position in which the marker 50 is retracted and a high position allowing the gripper to be gripped by the clamp 32 (arrow F 4 ). In the embodiment shown in Figure 3, the translational movement F 4 is obtained by pneumatic cylinder.

Au-dessus de son extrémité 50a, le marqueur 50 présente une zone de préhension 50c qui se trouve au niveau des mors 38 de la pince 32 lorsque celle-ci est en position basse et lorsque le capuchon 52 est en position haute.Above its end 50a, the marker 50 has a gripping zone 50c which is at the level of the jaws 38 of the clamp 32 when the latter is in the low position and when the cap 52 is in the high position.

Dans ces conditions, un déplacement transversal du chariot 22 et, par conséquent, de la pince 32 vers le marqueur 50 permet d'assurer la préhension automatique de ce dernier. En effet, lorsque les extrémités biseautées des surfaces de préhension 38a viennent au contact de la zone de préhension 50c du marqueur, les mors 38 sont automatiquement écartés à l'encontre de l'action du ressort 42. La poursuite du mouvement du chariot 22 portant la pince a ensuite pour effet d'emprisonner la zone 50c du marqueur entre les parties en arc de cercle des surfaces de préhension 38a.Under these conditions, a transverse movement of the carriage 22 and, consequently, of the clamp 32 towards the marker 50 makes it possible to ensure the automatic gripping of the latter. In fact, when the bevelled ends of the gripping surfaces 38a come into contact with the gripping zone 50c of the marker, the jaws 38 are automatically spread against the action of the spring 42. The continued movement of the carriage 22 carrying the clamp then has the effect of trapping the area 50c of the marker between the parts in an arc of the gripping surfaces 38a.

Le capuchon 52 est alors escamoté vers le bas sous l'action du vérin, pour libérer l'extrémité inférieure 50a du marqueur. Dans ces conditions, la pointe 50b du marqueur se trouve au niveau de la face supérieure du matériau à découper. Pour permettre d'amener le marqueur 50 jusqu'à la zone de marquage, l'excitation de l'électroaimant 46 est donc interrompue afin d'amener la pointe 50b du marqueur à un niveau situé sensiblement au-dessus de la face supérieure du matériau.The cap 52 is then retracted downwards under the action of the jack, to release the lower end 50a of the marker. Under these conditions, the tip 50b of the marker is located at the upper face of the material to be cut. To allow the marker 50 to be brought to the marking area, the excitation of the electromagnet 46 is therefore interrupted in order to bring the tip 50b of the marker to a level situated substantially above the upper face of the material. .

Le marquage est alors effectué après excitation de l'électroaimant 46, en combinant les déplacements transversaux du chariot 22 selon la flèche F2 et les déplacements longitudinaux du matériau selon la flèche Fi. A la fin de chaque tracé, l'excitation de l'électroaimant 46 est interrompue.The marking is then carried out after excitation of the electromagnet 46, by combining the transverse displacements of the carriage 22 according to arrow F 2 and the longitudinal displacements of the material according to arrow F i . At the end of each trace, the excitation of the electromagnet 46 is interrupted.

Lorsque les tracés sont terminés, les opérations qui viennent d'être décrites sont effectuées dans l'ordre inverse afin de ramener le marqueur dans son capuchon.When the plots are finished, the operations which have just been described are carried out in reverse order in order to bring the marker back into its cap.

Afin d'améliorer le contact entre le matériau M à découper et les courroies 12 et 14, on utilise des rouleaux presseurs 60 situés au-dessus des courroies et dont l'un seulement est représenté pour simplifier sur la figure 1. Ces rouleaux presseurs, disposés transversalement et dont les axes sont horizontaux, permettent de supprimer un glissement relatif éventuel entre le matériau et les courroies.In order to improve the contact between the material M to be cut and the belts 12 and 14, pressure rollers 60 are used located above the belts and only one of which is shown to simplify in FIG. 1. These pressure rollers, arranged transversely and whose axes are horizontal, make it possible to eliminate any relative slippage between the material and the belts.

Les rouleaux 60 sont de préférence escamotables comme l'illustre notamment la figure 6. A cet effet, les rouleaux 60 sont fixés à leurs extrémités sur les extrémités de deux leviers 62 articulées autour d'un axe horizontal 64 et dont les extrémités opposées sont reliées à un vérin 66. L'axe 64 ainsi que le corps du vérin 66 sont fixés sur le bâti 10 de la machine.The rollers 60 are preferably retractable as illustrated in particular in FIG. 6. For this purpose, the rollers 60 are fixed at their ends to the ends of two levers 62 articulated around a horizontal axis 64 and whose opposite ends are connected to a jack 66. The shaft 64 and the body of the jack 66 are fixed to the frame 10 of the machine.

Le vérin 64 permet à la fois d'appliquer le rouleau 60 correspondant avec une certaine force sur le matériau, et d'escamoter ce rouleau lorsque cela est nécessaire.The jack 64 makes it possible both to apply the corresponding roller 60 with a certain force to the material, and to retract this roller when necessary.

Lorsque le matériau à découper possède un bord émargé, la machine est généralement équipée sur toute sa longueur d'une réglette de guidage 68 (figure 2) adjacente à l'une des courroies latérales 12 et 14.When the material to be cut has a notched edge, the machine is generally equipped over its entire length with a guide strip 68 (Figure 2) adjacent to one of the side belts 12 and 14.

Afin d'appliquer le bord émargé du matériau à découper contre cette réglette, le rouleau presseur 60 situé à proximité de l'extrémité d'entrée 10b du bâti de la machine a son axe horizontal légèrement incliné par rapport à la direction transversale correspondant à la flèche F2. Plus précisément, l'extrémité de ce rouleau 60 adjacente à la réglette 68 est plus proche de l'extrémité d'entrée 10b du bâti que l'extrémité opposée de ce rouleau 60. Lors de l'avance du matériau sur les courroies crantées 12 (flèche F'i), cette disposition particulière du rouleau 60 situé à l'entrée de la machine a pour effet d'appliquer sur le matériau un effort transversal t dirigé vers la réglette de guidage 68. Le contact du bord émargé du matériau avec cette réglette est ainsi assuré.In order to apply the edge of the material to be cut against this strip, the pressure roller 60 located near the inlet end 10b of the machine frame has its horizontal axis slightly inclined with respect to the transverse direction corresponding to the arrow F 2 . More precisely, the end of this roller 60 adjacent to the strip 68 is closer to the inlet end 10b of the frame than the opposite end of this roller 60. When the material advances on the toothed belts 12 (arrow F'i), this particular arrangement of the roller 60 located at the entrance to the machine has the effect of applying a transverse force t directed towards the guide strip 68 on the material. The contact of the edge of the material with this strip is thus ensured.

Conformément une caractéristique essentielle de l'invention, la machine comprend des modules d'alimentation interchangeables 70 sur lesquels peuvent être préparés à l'avance les rouleaux de matériau M à découper. Un module interchangeable 70 va maintenant être décrit en détail, notamment en se référant aux figures 7 à 10.According to an essential characteristic of the invention, the machine comprises interchangeable supply modules 70 on which the rolls of material M to be cut can be prepared in advance. An interchangeable module 70 will now be described in detail, in particular with reference to FIGS. 7 to 10.

Le module d'alimentation 70 comprend un châssis rigide 72 reposant sur le sol par exemple par des roulettes 74 permettant son déplacement. Ce châssis 72 présente une face avant 72a destinée à être placée en regard de l'extrémité d'entrée 10a du bâti de la machine.The power supply module 70 comprises a rigid chassis 72 resting on the ground for example by rollers 74 allowing its movement. This chassis 72 has a front face 72a intended to be placed opposite the inlet end 10a of the frame of the machine.

Pour permettre l'interchangeabilité du module 70, celui-ci est connecté au bâti 10 de la machine par des moyens de raccordement déconnectables assurant également le positionnement latéral du module par rapport au bâti.To allow the interchangeability of the module 70, it is connected to the frame 10 of the machine by disconnectable connection means also ensuring the lateral positioning of the module relative to the frame.

Dans le mode de réalisation représenté sur la figure 8, ces moyens de raccordement et de positionnement comprennent deux ventouses magnétiques 76 montées sur l'extrémité avant 10a du bâti de la machine, en regard de deux plaques métalliques 78 situées sur la face avant 72a du châssis du module d'alimentation 70. Un intrrupteur électrique 80 également placé sur l'extrémité avant du bâti de la machine commande automatiquement l'excitation des ventouses magnétiques 76 lorsque la face avant du châssis du module d'alimentation est amenée au contact de l'extrémité d'entrée du bâti de la machine.In the embodiment shown in FIG. 8, these connection and positioning means comprise two magnetic suction cups 76 mounted on the front end 10a of the machine frame, opposite two metal plates 78 located on the front face 72a of the machine. power module chassis 70. An electrical switch 80 also placed on the front end of the machine frame automatically controls the excitation of the magnetic suction cups 76 when the front face of the power module chassis is brought into contact with the entry end of the machine frame.

Comme l'illustre plus précisément la figure 8, ces moyens de raccordement et de positionnement déconnectables comprennent de plus un centreur 82 à extrémité cônique, faisant saillie sur l'extrémité d'entrée 10a du bâti de la machine. Lors du raccordement du module 70 sur le bâti 10, ce centreur 82 pénètre dans une rainure oblongue 84, orientée verticalement, formée dans la plaque 78 placée en vis-à-vis du centreur 82. Il est à noter que le positionnement latéral ainsi obtenu est suffisant pour assurer un positionnement satisfaisant de la cassette d'alimentation par rapport au bâti de la machine. En effet, le positionnement en hauteur est réalisé par construction.As illustrated more precisely in FIG. 8, these disconnectable connection and positioning means further comprise a centralizer 82 with conical end, projecting from the inlet end 10a of the frame of the machine. When the module 70 is connected to the frame 10, this centralizer 82 penetrates into an oblong groove 84, oriented vertically, formed in the plate 78 placed opposite the centralizer 82. It should be noted that the lateral positioning thus obtained is sufficient to ensure satisfactory positioning of the feed cassette relative to the machine frame. In fact, the positioning in height is achieved by construction.

Sur sa face supérieure, le bâti 72 de la cassette d'alimentation 70 forme un réceptacle pour le rouleau de matériau M à découper. De façon plus précise, le rouleau de matériau M est monté sur un mandrin de révolution 88 dont les extrémités reposent sur des entailles 86 en forme de V constituant le réceptacle.On its upper face, the frame 72 of the supply cassette 70 forms a receptacle for the roll of material M to be cut. More precisely, the roll of material M is mounted on a revolution mandrel 88, the ends of which rest on V-shaped notches 86 constituting the receptacle.

Ces entailles sont formées sur des plaques latérales 90 faisant saillie verticalement vers le haut sur les côtés du châssis 72, à proximité des extrémités des plaques les plus éloignées de la face avant 72a.These notches are formed on side plates 90 projecting vertically upwards on the sides of the frame 72, near the ends of the plates furthest from the front face 72a.

Lorsque le mandrin 88 est reçu dans son réceptacle, l'extrémité du matériau M est disposée comme l'illustrent notamment les figures 7 et 9, de façon à former une boucle. Ainsi, le matériau M passe d'abord au-dessus d'un rouleau fou 92, puis sous un rouleau de tension mobile 94, et enfin au-dessus d'un deuxième rouleau fou 96. Les axes des rouleaux 92, 94 et 96 sont disposés transversalement, parallèlement à l'axe du mandrin 88 lorsque celui-ci est reçu sur son réceptacle. Les axes des rouleaux 92 et 96 sont alors situés approximativement au même niveau que l'axe du mandrin 88, alors que l'axe du rouleau 94 est situé en permanence à un niveau inférieur.When the mandrel 88 is received in its receptacle, the end of the material M is arranged as illustrated in particular in FIGS. 7 and 9, so as to form a loop. Thus, the material M passes first over an idler roller 92, then under a movable tension roller 94, and finally over a second idler roller 96. The axes of the rollers 92, 94 and 96 are arranged transversely, parallel to the axis of the mandrel 88 when the latter is received on its receptacle. The axes of the rollers 92 and 96 are then located approximately at the same level as the axis of the mandrel 88, while the axis of the roller 94 is permanently located at a lower level.

Les extrémités du rouleau de tension 94 sont logées dans des rainures verticales 98 (figure 8) formées sur les faces latérales du châssis 72, de telle sorte qu'il repose par gravité sur le matériau M pour le maintenir sous tension en permanence.The ends of the tension roller 94 are housed in vertical grooves 98 (FIG. 8) formed on the lateral faces of the frame 72, so that it rests by gravity on the material M to keep it under tension at all times.

Au-delà du rouleau 96, l'extrémité de la bande de matériau M est placée sur la face supérieure plane et horizontale d'une réglette de supportage escamotable 100. Le niveau de cette face supérieure coïncide avec le niveau de la table mobile formée par les courroies 12 et 14.Beyond the roller 96, the end of the strip of material M is placed on the flat and horizontal upper face of a retractable support strip 100. The level of this upper face coincides with the level of the movable table formed by belts 12 and 14.

La réglette 100 est supportée par le châssis 72 du module 70 de façon à pouvoir se déplacer horizontalement en rapprochement et en éloignement de la face avant 72a sur des colonnes 102. Comme l'illustre notamment la figure 9, lorsque le module 70 est séparé du bâti de la machine, des ressorts 104 placés sur les colonnes 102 maintiennent la réglette 100 écartée de la face avant 72a du châssis. Dans ces conditions, le bord avant de la bande de matériau M est aligné avec le bord avant de la réglette 100.The strip 100 is supported by the frame 72 of the module 70 so as to be able to move horizontally in approach and away from the front face 72a on columns 102. As illustrated in particular in FIG. 9, when the module 70 is separated from the frame of the machine, springs 104 placed on the columns 102 keep the strip 100 spaced from the front face 72a of the chassis. Under these conditions, the front edge of the strip of material M is aligned with the front edge of the strip 100.

Comme on le voit sur la figure 10, l'accostage du module d'alimentation 70 sur le bâti de la machine a pour effet de repousser la réglette 100 vers la face avant 72a, à l'encontre des ressorts 104. L'extrémité de la bande de matériau M se trouve ainsi engagée progressivement sur l'extrémité de la série de courroies 12.As can be seen in FIG. 10, the docking of the supply module 70 on the frame of the machine has the effect of pushing the strip 100 towards the front face 72a, against the springs 104. The end of the strip of material M is thus progressively engaged on the end of the series of belts 12.

Lorsque l'opérateur met en place la bande de matériau M de la manière qui vient d'être décrite, il aligne le bord émargé du matériau sur des guides latéraux 106 (figure 7). Pour assurer le maintien du matériau dans cette position jusqu'au moment où la machine est mise en marche, après l'accostage du module d'alimentation, ce dernier est également équipé de moyens de pinçage du matériau.When the operator sets up the strip of material M in the manner which has just been described, he aligns the emarged edge of the material on lateral guides 106 (FIG. 7). To maintain the material in this position until the machine is started, after docking the feed module, the latter is also equipped with material clamping means.

Dans le mode de réalisation représenté sur les figures 7, 9 et 10, ces moyens de pinçage comprennent un bras transversal horizontal 108 dont les extrémités sont fixées sur des leviers 110 articulés en 112 sur des parties des plaques verticales 90 faisant saillie vers le haut entre les rouleaux 92 et 96. Sur sa face inférieure, le bras transversal 108 porte des patins 114, par l'intermédiaire de liaisons rotulantes.In the embodiment shown in FIGS. 7, 9 and 10, these pinching means comprise a horizontal transverse arm 108 whose ends are fixed on levers 110 articulated at 112 on parts of the vertical plates 90 projecting upwards between the rollers 92 and 96. On its underside, the transverse arm 108 carries pads 114, by means of swiveling connections.

Comme l'illustre notamment la figure 9, les patins 114 reposent normalement par gravité sur le matériau M, de sorte que celui-ci est pincé entre les patins 114 et une face d'appui horizontale du châssis 72 immédiatement adjacente à la face avant 72a de ce dernier.As illustrated in particular in FIG. 9, the pads 114 normally rest by gravity on the material M, so that the latter is pinched between the pads 114 and a horizontal bearing face of the frame 72 immediately adjacent to the front face 72a of the last.

Comme on le voit sur la figure 10, lorsque le module d'alimentation 70 est accosté sur le bâti de la machine, les patins 114 sont écartés du matériau en bande M sous l'action d'un vérin 116 monté dans le bâti 10 de la machine. De façon plus précise, le vérin 116 est équipé d'une tige poussoir 116a faisant saillie verticalement vers le haut de façon à soulever l'un des leviers 110 lorsque le vérin est actionné. L'extrémité du matériau M est alors libérée et ce matériau peut être amené jusqu'au poste de découpe 18 par les courroies transporteuses 12.As can be seen in FIG. 10, when the supply module 70 is docked on the frame of the machine, the pads 114 are moved away from the strip material M under the action of a jack 116 mounted in the frame 10 of the machine. More precisely, the jack 116 is equipped with a push rod 116a projecting vertically upwards so as to raise one of the levers 110 when the jack is actuated. The end of the material M is then released and this material can be brought to the cutting station 18 by the conveyor belts 12.

Simultanément, l'avance du matériau en bande M est assurée par un ensemble moteur 118 (figures 2 et 7) monté sur un châssis annexe 120 lié de façon rigide au bâti 10 de la machine. Ce châssis annexe 120 est disposé sur le côté du module d'alimentation 70 lorsque celui-ci est raccordé au bâti, de telle sorte que l'arbre de sortie de l'ensemble moteur 118 soit alors aligné avec l'axe du mandrin 88 portant le rouleau de matériau en bande M.Simultaneously, the advancement of the strip material M is ensured by an engine assembly 118 (FIGS. 2 and 7) mounted on an auxiliary frame 120 rigidly connected to the frame 10 of the machine. This additional chassis 120 is disposed on the side of the power supply module 70 when the latter is connected to the frame, so that the output shaft of the motor assembly 118 is then aligned with the axis of the mandrel 88 carrying the roll of strip material M.

L'ensemble moteur 118 comprend un moteur 122 commandant la rotation d'un embrayage pneumatique 124 apte à venir se loger dans une extrémité tubulaire 88a formée à cet effet dans le mandrin 88. L'ensemble moteur 118 est supporté par le châssis annexe 120 de façon à pouvoir se déplacer transversalement entre une position arrière représentée sur les figures 2 et 3, permettant la mise en place et l'enlèvement du module 70, et une position avant d'entraînement, dans laquelle l'embrayage pneumatique 124 est logé dans l'extrémité tubulaire 88a du mandrin. Le déplacement de l'ensemble moteur 118 est commandé par tout moyen approprié représenté schématiquement en 126 sur la figure 7.The motor assembly 118 comprises a motor 122 controlling the rotation of a pneumatic clutch 124 capable of being housed in a tubular end 88a formed for this purpose in the mandrel 88. The motor assembly 118 is supported by the auxiliary chassis 120 of so as to be able to move transversely between a rear position shown in FIGS. 2 and 3, allowing the insertion and removal of the module 70, and a front drive position, in which the pneumatic clutch 124 is housed in the tubular end 88a of the mandrel. The movement of the motor assembly 118 is controlled by any suitable means shown diagrammatically at 126 in FIG. 7.

Dans une commande automatisée, la translation de l'ensemble moteur 118 permettant d'amener l'embrayage 124 dans l'extrémité tubulaire 88a, de même que le gonflage de cet embrayage, se font automatiquement après accostage de la cassette 70 sur le bâti de la machine.In an automated control, the translation of the engine assembly 118 allowing the clutch 124 to be brought into the tubular end 88a, as well as the inflation of this clutch, takes place automatically after docking of the cassette 70 on the frame of the machine.

Dans le même esprit, les différents organes constituant la machine qui vient d'être décrite peuvent également être automatisés afin de permettre un fonctionnement particulièrement rapide et efficace.In the same spirit, the various organs constituting the machine which has just been described can also be automated in order to allow particularly fast and efficient operation.

De préférence, le rouleau 94 assurant sur la cassette d'alimentation la tension du matériau M peut également servir à contrôler la longueur de bande déroulée et, par conséquent, l'actionnement du moteur 122. A cet effet, l'extrémité du rouleau 94 adjacent au châssis annexe 120 peut venir en contact avec un contact bas 128 nécessitant l'arrêt du moteur 122 ou avec un contact haut 130 dont l'enclenchement nécessite au contraire la mise en oeuvre du moteur 122. Ces deux contacts permettent de compléter l'automatisation de la machine.Preferably, the roller 94 ensuring the tension of the material M on the supply cassette can also be used to control the length of the unwound strip and, consequently, the actuation of the motor 122. For this purpose, the end of the roller 94 adjacent to the auxiliary frame 120 can come into contact with a low contact 128 requiring the engine 122 to stop or with a high contact 130 whose engagement requires on the contrary the implementation of the engine 122. These two contacts make it possible to complete the machine automation.

Bien entendu, le déplacement de la cassette d'alimentation 70 entre le poste dans lequel un opérateur assure la mise en place du matériau M de la manière décrite précédemment en référence aux figures 3 et 5 et l'accostage de la cassette sur la machine peuvent se faire de manière automatique. Par exemple, la cassette peut prendre la forme d'un chariot filoguidé ou utiliser toute autre technique de déplacement robotisée analogue.Of course, the movement of the supply cassette 70 between the station in which an operator ensures the placement of the material M in the manner described above with reference to Figures 3 and 5 and the docking of the cassette on the machine can be done automatically. For example, the cassette can take the form of a wire-guided cart or use any other similar robotic movement technique.

Il est clair que l'utilisation de cassettes d'alimentation 70 conformes à l'invention permet de faciliter le changement du matériau lorsque le rouleau est terminé. En effet, la préparation d'une cassette peut être faite en toute tranquillité sans pénaliser pour autant le rendement de la machine. Au contraire, ce rendement se trouve sensiblement accru, de même que les coûts d'exploitation.It is clear that the use of feed cassettes 70 in accordance with the invention makes it possible to facilitate the change of the material when the roll is finished. Indeed, the preparation of a cassette can be done in peace without penalizing the performance of the machine. On the contrary, this yield is significantly increased, as are operating costs.

Bien entendu, la cassette d'alimentation 70 pourrait être utilisée dans toute autre machine automatique assurant le traitement et/ou le contrôle d'un matériau en rouleau de toute nature.Of course, the feed cassette 70 could be used in any other automatic machine ensuring the processing and / or control of a roll material of any kind.
