Abstract

The continuous puller for a straight row knitting machine with one or more sections (1, 2) consists of two elastic belts (5, 6) rotated in opposite directions by two horizontal shafts (7, 8) driven by two-way motors and passing over return members (10, 11) located close to the stitchforming zone. The belts are fitted with an internal mechanism (21, 22) which allows the shape of their outer surfaces to be modified, varying the pulling effort applied to the knitted material. The belt shape modification mechanism consists of pressure elements inside the belts which vary the area of the contact surface between at least one belt and the knitting. The pressure elements are in the shape of elongated bodies such as rollers moved by a system of endless screws, and the belts have outer surface grooves lying parallel to the axes of the drive shafts or in helical lines.

Description

La présente invention a pour objet un dispositif de tirage en continu pour machine à tricoter rectiligne à une ou plusieurs fontures comprenant deux courroies élastiques entraínées en continu en sens opposé par deux arbres horizontaux et passant sur au moins deux renvois situés à proximité de la zone de formation des mailles, dans lequel les renvois sont montés sur des bâtis supportés par les arbres d'entraínement de telle manière que les courroies sont appliquées l'une contre l'autre sous l'effet des forces de frottement exercées sur le bâti par les arbres d'entraínement.The present invention relates to a device for continuous drawing for straight knitting machine one or more needle beds including two straps elastic continuously driven in opposite directions by two horizontal trees and passing on at least two references located near the mesh formation area, in which the references are mounted on racks supported by the drive shafts in such a way that the belts are applied against each other under the effect of the friction forces exerted on the built by the drive trees.

Un tel dispositif est décrit dans le brevet CH 633 334 (US 4,359,881). Ce dispositif développé par le demandeur est utilisé par ce dernier avec succès depuis près de vingt ans. Le tricot est tiré en douceur, par frottement-glissement, entre les courroies, de façon continue, ou au fur et à mesure de la formation des mailles et tout près de la zone de formation de ces mailles.Such a device is described in patent CH 633 334 (US 4,359,881). This device developed by the applicant has been used by the latter successfully for almost twenty years. The knit is pulled gently, by friction-sliding, between the belts, so continuous, or as the training of meshes and very close to the formation zone of these sts.

Les courroies s'étendent sur toute la longueur de la machine et le dispositif de tirage exerce une traction uniforme sur toute la longueur et sur les deux faces du tricot. Or, les structures de tricots qu'il est possible de réaliser sur les machines rectilignes modernes sont de plus en plus complexes, par exemple la production d'articles tridimensionnels. Ces machines permettent de réaliser des tricotages en forme, des tricotages d'articles complets, tricotés et entièrement finis sur les machines, tels que des pull-overs. Lors de tels tricotages, des nappes de tricot ne sont pas produites en même temps sur la fonture avant sur la fonture arrière et qui peuvent souvent rester en attente l'une par rapport à l'autre pendant de nombreux passages du chariot porte-cames commandant les aiguilles à tricoter, le tricotage s'effectuant alors sur toute la fonture opposée ou seulement sur une zone de cette fonture.The belts extend over the entire length of the machine and the pulling device pulls uniform over the entire length and on both sides of the knitting. Now the knitting structures that it is possible to realize on modern straight machines are increasingly complex, for example production three-dimensional items. These machines allow make shaped knits, knits of complete, knitted and fully finished articles on machines, such as sweaters. During such knitting, knitting tablecloths are not produced at the same time on the needle bed before on the needle bed back and who can often stand by one compared to each other for many passages of the cam holder carriage controlling knitting needles, knitting then takes place on the whole needle bed opposite or only on an area of this needle bed.

Il serait donc utile de pouvoir tirer différemment les nappes de tricot qui ne sont pas produites en même temps et, au besoin, de pouvoir moduler automatiquement la force de traction sur la largeur de tricotage, par zone, les structures de mailles produites pouvant être de forme et de densité différentes sur la largeur, la pression exercée sur le tricot devant à cet effet pouvoir varier localement selon la nécessité, notamment pour produire des articles tridimensionnels.It would therefore be useful to be able to draw the knitted tablecloths that are not produced at the same time and, if necessary, to be able to automatically modulate the tensile force over the knitting width, by area, the mesh structures produced being able to be of different shape and density across the width, the pressure exerted on the knit in front for this purpose be able to vary locally as required, including to produce three-dimensional items.

L'invention a pour but de satisfaire à ces exigences. A cet effet, le dispositif de tirage selon l'invention est caractérisé en ce qu'il comprend des moyens de modification de la forme de l'enveloppe des courroies de manière à différencier la force de tirage exercée sur la ou les nappes de tricot.The invention aims to meet these requirements. AT For this purpose, the drawing device according to the invention is characterized in that it includes means for modification of the shape of the belt envelope so as to differentiate the pulling force exerted on the or knitted tablecloths.

Ces moyens de modification de la forme de l'enveloppe des courroies peuvent être de diverses sortes, utilisés individuellement ou en combinaison.These means of modifying the shape of the envelope belts can be of various kinds, used individually or in combination.

Selon un mode d'exécution, les moyens de modification de la forme de l'enveloppe des courroies de tirage sont constitués de moyens de pression montés sur les bâtis, ces moyens de pression exerçant une pression sur les courroies de manière à augmenter leur tension.According to one embodiment, the means for modifying the envelope shape of the pulling belts are consisting of pressure means mounted on the frames, these means of pressure exerting pressure on the belts so as to increase their tension.

L'augmentation de la tension de la courroie a pour effet d'augmenter la pression de l'arbre d'entraínement sur le bâti et par conséquent la force de frottement et partant le couple exercé sur le bâti et la force de pincement exercée par la courroie sur le tricot.Increasing the belt tension has the effect increase the pressure of the drive shaft on the frame and therefore the frictional force and therefore the torque exerted on the frame and the gripping force exerted by the belt on the knitted fabric.

Selon un autre mode d'exécution, les moyens de modification de la forme de l'enveloppe des courroies de tirage augmentent la surface de contact d'au moins l'une des courroies avec le tricot.According to another embodiment, the means of modification of the shape of the belt envelope draw increases the contact surface by at least one belts with knitting.

Selon un mode d'exécution, les moyens de modification de la forme de l'enveloppe des courroies sont constitués sur chaque bâti, de préférence segmentés, d'au moins un corps allongé et d'axe parallèle à l'axe de l'arbre d'entraínement, monté sur le bâti entre le bâti et la courroie, de longueur égale à une fraction de celle de la fonture, avantageusement inférieure à la longueur d'un segment de bâti et déplaçable axialement sur les bâtis. Des moyens d'entraínement sont prévus pour l'entraínement axial de ces corps. Ces corps écartent les courroies des bâtis et par là modifient la forme de l'enveloppe des courroies.According to one embodiment, the means for modifying the envelope shape of the belts are made up on each frame, preferably segmented, of at least one elongated body and axis parallel to the axis of the shaft drive, mounted on the frame between the frame and the belt, length equal to a fraction of that of the needle bed, advantageously less than the length of a frame segment and axially movable on the built. Training means are provided for the axial drive of these bodies. These bodies spread frame belts and thereby change the shape of the envelope of the belts.

Ces corps allongés sont avantageusement constitués de rouleaux montés librement, selon leur axe de déplacement, sur des vis sans fin, entre deux écrous baladeurs. These elongated bodies advantageously consist of rollers mounted freely, along their axis of displacement, on worms, between two nuts players.

La présence des corps allongés, respectivement des rouleaux, a pour effet d'écarter la courroie du bâti et par là d'augmenter la tension de la courroie.The presence of the elongated bodies, respectively rollers, has the effect of spreading the belt of the frame and thereby increasing the tension of the belt.

De manière à augmenter localement la force de tirage, les bâtis sont avantageusement segmentés en plusieurs bâtis autonomes, c'est-à-dire indépendants les uns des autres en ce qui concerne leur entraínement par l'arbre d'entraínement.In order to locally increase the pulling force, the frames are advantageously segmented into several autonomous frames, that is to say independent of each other others regarding their tree training drive.

Chaque bâti sera équipé de préférence d'au moins un rouleau monté sur le côté intérieur et/ou extérieur du bâti.Each frame will preferably be equipped with at least one roller mounted on the inside and / or outside of the frame.

Le dispositif est équipé de préférence de deux moteurs à vitesse variable, à deux sens de rotation, entraínant respectivement chacun des arbres.The device is preferably equipped with two motors with variable speed, with two directions of rotation, driving respectively each of the trees.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention, ainsi qu'une variante de celui-ci.The accompanying drawing shows, by way of example, a mode of the invention, as well as a variant of this one.

La figure 2 est une vue en perspective du dispositif de tirage seul, sans les fontures de la machine.Figure 2 is a perspective view of the device print only, without the needle beds of the machine.

La figure 4 est une vue en coupe transversale selon IV-IV de la figure 3, le second système du dispositif de tirage étant également représenté symétrique au premier.Figure 4 is a cross-sectional view along IV-IV in Figure 3, the second system of the print is also shown symmetrical to the first.

La figure 5 est une vue en coupe selon V-V de la figure 3 avec les deux systèmes du dispositif de tirage.Figure 5 is a sectional view along V-V of the figure 3 with the two systems of the drawing device.

La figure 6 représente une modification du dispositif de tirage.Figure 6 shows a modification of the draw.

La machine à tricoter rectiligne représentée à la figure 1 comprend, de manière connue, deux fontures opposées 1 et 2 fixées sur un bâti 3. On distingue deux rainures 4 de chacune des fontures, rainures dans lesquelles viennent se loger les aiguilles et leurs clavettes (non représentées).The straight knitting machine shown in figure 1 comprises, in known manner, two opposite needle beds 1 and 2 fixed on a frame 3. There are two grooves 4 of each of the needle beds, grooves in which come to house the needles and their keys (not shown).

Sous les fontures se trouve un dispositif de tirage en continu dont les éléments essentiels sont les mêmes que ceux décrits dans le brevet CH 633 334 (US 4,359,881). Ce dispositif est constitué de deux systèmes A et B comprenant essentiellement deux courroies sans fin 5 et 6, en caoutchouc lisse ou en matériau analogue, entraínées respectivement par deux arbres 7 et 8 s'étendant parallèlement à l'axe de la machine et symétriquement au plan de symétrie 9 de celle-ci, les deux courroies 5 et 6 passant en outre sur deux renvois 10 et 11 constitués de simples barres cylindriques en métal de faible diamètre supportées respectivement par deux bâtis 12 et 13 eux-mêmes supportés par les arbres d'entraínement 7 et 8. Les bâtis 12 et 13 sont constitués de blocs essentiellement prismatiques s'étendant sur toute la longueur des arbres 7 et 8 et présentant une gorge de surface cylindrique par laquelle il s'appuie en glissant sur les arbres 7 et 8, une gorge opposée servant de pallier aux renvois 10 et 11. Les bâtis 12 et 13 sont réalisés de préférence en une matière synthétique à faible coefficient de frottement. Les courroies élastiques 5 et 6 sont légèrement sous tension et cette tension applique les bâtis 10 et 13 respectivement contre chacun des arbres 7 et 8 entraínés en sens opposé comme indiqué par les flèches. Les bâtis 12 et 13 ont tendance à être entraínés par frottement par les arbres d'entraínement 7 et 8, cet entraínement ayant pour effet d'appliquer les courroies 5 et 6 l'une contre l'autre idéalement selon le plan de symétrie 9 de la machine, comme décrit dans le brevet précité.Under the needle beds is a pulling device in continuous whose essential elements are the same as those described in patent CH 633 334 (US 4,359,881). This device consists of two systems A and B essentially comprising two endless belts 5 and 6, made of smooth rubber or similar material, driven respectively by two shafts 7 and 8 extending parallel to the axis of the machine and symmetrically to the plane of symmetry 9 thereof, the two belts 5 and 6 also passing over two references 10 and 11 consisting of simple cylindrical bars in small diameter metal supported respectively by two frames 12 and 13 themselves supported by the trees 7 and 8. The frames 12 and 13 are made up of essentially prismatic blocks extending over the entire length of shafts 7 and 8 and having a cylindrical surface groove through which it is supported by sliding on the trees 7 and 8, a groove opposite serving to overcome references 10 and 11. The frames 12 and 13 are preferably made in one synthetic material with low coefficient of friction. The elastic belts 5 and 6 are slightly under tension and this tension applies the frames 10 and 13 respectively against each of the shafts 7 and 8 entrained in the opposite direction as indicated by the arrows. The frames 12 and 13 tend to be dragged by the drive shafts 7 and 8, this drive having the effect of applying belts 5 and 6 to one against the other ideally according to the plane of symmetry 9 of the machine, as described in the aforementioned patent.

La figure 1 montre en outre un autre moyen de différenciation de la force de tirage dont il sera question plus loin et on pourra donc revenir à cette figure 1.Figure 1 also shows another way to differentiation of the pulling force which it will be question further on so we can come back to this figure 1.

La figure 2 illustre l'un des moyens de modification de la forme de l'enveloppe des courroies de tirage. Ces moyens sont constitués de deux moteurs 14 et 15 à vitesse variable entraínant respectivement chacun des arbres d'entraínement 7 et 8. Ces moteurs sont commandés de manière indépendante et leur sens de rotation peut être inversé comme indiqué par les doubles flèches. Ces moteurs 14 et 15 permettent de faire varier la vitesse des moteurs, ce qui a pour effet d'appliquer plus ou moins fort les courroies l'une contre l'autre, c'est-à-dire de faire varier la surface de contact d'au moins l'une des courroies avec le tricot, cette variation s'accompagnant d'une modification de la forme de l'enveloppe de la courroie et d'une variation de la force de tirage. Les moteurs permettent également de faire varier la force de tirage sur des nappes tricotées sur chacune des deux fontures. Ainsi, une des nappes de tricot, avant ou arrière, peut progresser plus rapidement que la nappe opposée. L'une des deux courroies peut être totalement arrêtée, le tirage ne se faisant alors que par la courroie opposée. Le sens de rotation de l'un des moteurs peut être inversé de telle sorte que la nappe de tricot correspondante peut être plus facilement retirée vers le haut si nécessaire.Figure 2 illustrates one of the means of modifying the shape of the envelope of the pulling belts. These means consist of two motors 14 and 15 to variable speed respectively driving each of drive shafts 7 and 8. These motors are controlled independently and their direction of rotation can be reversed as indicated by the double arrows. These motors 14 and 15 allow the speed to be varied motors, which has the effect of applying more or weaker the belts against each other, that is to say to vary the contact surface by at least one of the belts with knitting, this variation accompanied by a change in the form of the belt wrap and a variation in the pulling force. The motors also allow vary the pulling force on knitted tablecloths on each of the two needle beds. So, one of the tablecloths of knitting, front or back, can progress more quickly than the opposite tablecloth. One of the two belts can be completely stopped, pulling is not doing so only by the opposite belt. The meaning of rotation of one of the motors can be reversed so so the corresponding knitting tablecloth can be more easily pulled up if necessary.

On aperçoit également à la figure 2 un autre perfectionnement qui sera décrit ci-après en se référant aux figures 3 à 5 qui représentent un autre exemple de moyen permettant de faire varier la force de tirage par la variation de la tension sur les courroies 5 et 6.We also see in Figure 2 another improvement which will be described below with reference in Figures 3 to 5 which represent another example of means for varying the pulling force by the variation of the tension on belts 5 and 6.

Les bâtis 12 et 13 (figure 3) présentent, sur leurs flancs, des rainures longitudinales de profil en V, telles que la rainure 16, s'étendant parallèlement aux axes des arbres d'entraínement 7 et 8. Dans chacune de ces rainures sont montées deux vis sans fin telles que les vis 17 et 18. Sur ces vis sont montées des écrous 19 et 20, retenu en rotation par le profil des gorges 16. Entre ces écrous 19 et 20 sont montés, dans chaque rainure 16, deux rouleaux tubulaires, à savoir un premier rouleau 21 et un second rouleau 22 pouvant tourner librement sur les vis 17 et 18, mais retenus axialement par les écrous baladeurs 19 et 20. Les vis sans fin 17 sont entraínables individuellement par des moteurs électriques tels que les moteurs 23 et 25 et les vis sans fin 18 sont entraínables par des moteurs électriques 24 et 26. La commande automatique de ces moteurs permet de déplacer les rouleaux 21 et 22 dans les rainures 16 le long du bâti 12. Les moteurs 23 et 24 entraínent directement les vis sans fin 17 et 18 alors que les moteurs 25 et 26 entraínent les vis sans fin correspondantes par l'intermédiaire de courroies 27 et 28.The frames 12 and 13 (Figure 3) have, on their sides, longitudinal V-shaped grooves, such as groove 16, extending parallel to the axes of drive shafts 7 and 8. In each of these grooves are mounted two worms such as the screws 17 and 18. On these screws are mounted nuts 19 and 20, held in rotation by the profile of the grooves 16. Between these nuts 19 and 20 are mounted, in each groove 16, two tubular rolls, namely one first roller 21 and a second roller 22 which can turn freely on screws 17 and 18, but retained axially by the sliding nuts 19 and 20. The screws endless 17 are individually trainable by electric motors such as motors 23 and 25 and worms 18 can be driven by motors 24 and 26. The automatic control of these motors move the rollers 21 and 22 in the grooves 16 along the frame 12. The motors 23 and 24 drive the worms 17 and 18 directly that the motors 25 and 26 drive the worms corresponding via belts 27 and 28.

La présence d'un rouleau sous la courroie 5 a pour effet de modifier la forme de l'enveloppe des courroies, en allongeant le chemin de la courroie 5, c'est-à-dire d'augmenter localement la tension de cette courroie. L'augmentation de la tension sur la courroie a pour effet d'augmenter la force avec laquelle la courroie est appliquée contre la courbe opposée, c'est-à-dire d'augmenter la force de traction sur le tricot. Ceci s'explique tout simplement par l'augmentation de la pression de l'arbre d'entraínement sur le bâti, c'est-à-dire l'augmentation de la force de frottement entre l'arbre d'entraínement et le bâti.The presence of a roller under the belt 5 has the effect to modify the shape of the belt envelope, by lengthening the path of the belt 5, i.e. locally increase the tension of this belt. The increase in tension on the belt effect of increasing the force with which the belt is applied against the opposite curve, i.e. increase the pulling force on the knitted fabric. This is simply explained by the increase in pressure of the drive shaft on the frame, that is to say increasing the frictional force between the drive shaft and the frame.

Comme on peut le voir aux figures 3 à 5, les rouleaux peuvent être disposés aussi bien sur les faces intérieures des bâtis 12 et 13, c'est-à-dire les faces en regard l'une de l'autre, que sur les faces extérieures. On voit en outre à la figure 4 que les rouleaux montés sur les faces intérieures des bâtis ont pour effet d'augmenter la longueur du tricot pincé entre les courroies, ce qui a pour effet d'augmenter localement la traction sur le tricot.As can be seen in Figures 3 to 5, the rollers can be arranged on both sides interior of frames 12 and 13, i.e. the faces facing each other, only on the faces exterior. We also see in Figure 4 that the rollers mounted on the inside faces of the frames have increases the length of the pinched knit between the belts, which has the effect of increasing locally pulling on the knit.

La figure 5 montre une zone des courroies 5 et 6 exemptes de rouleaux. Dans ce cas, la force de tirage est minimale.Figure 5 shows an area of belts 5 and 6 free of rollers. In this case, the pulling force is minimal.

Le mode d'exécution représenté comprend quatre paires de rouleaux par bâti. Il serait bien entendu possible de limiter ces rouleaux à une paire par bâti, voire un rouleau par bâti. Les rouleaux pourraient être en outre montés sur un seul des bâtis.The embodiment shown comprises four pairs of rolls per frame. It would of course be possible to limit these rollers to one pair per frame, or even one roll per frame. The rollers could also be mounted on only one of the frames.

Les rouleaux ne doivent pas nécessairement pouvoir tourner sur les vis 17 et 18. Les rouleaux pourraient donc être remplacés par des tubes de section non circulaire, particulièrement polygonale.The rollers need not be able to turn on screws 17 and 18. The rollers could therefore be replaced by tubes of section not circular, particularly polygonal.

Les rouleaux pourraient être remplacés par tout corps allongé, monté rotativement ou non.Rollers could be replaced by any body elongated, rotatably mounted or not.

Une autre amélioration consiste à rainurer les courroies, comme représenté à la figure 3 pour la courroie 5. Ces rainures 30 ont ici la forme de cannelures parallèles s'étendant parallèlement à l'axe du système, c'est-à-dire parallèlement à l'axe de l'arbre d'entraínement 7. Ces rainures 30 ont pour effet d'augmenter l'adhérence de la courroie 5 sur le tricot, ainsi que l'adhérence des nappes de tricot avant et arrière entre elles, tout en permettant malgré tout le glissement du tricot, afin d'éviter sa détérioration par une friction excessive. En principe les deux courroies 5 et 6 sont rainurées de la même manière.Another improvement is to groove the belts, as shown in figure 3 for the belt 5. These grooves 30 have here the form of parallel grooves extending parallel to the axis of the system, i.e. parallel to the axis of the drive shaft 7. These grooves 30 have the effect increase the adhesion of the belt 5 on the knitted fabric, as well as the adhesion of the knitted tablecloths before and back between them, while still allowing the slip of the knitted fabric, in order to avoid its deterioration by excessive friction. In principle the two belts 5 and 6 are grooved in the same way.

En variante, les rainures pourraient être obliques relativement à l'axe du système, c'est-à-dire pratiquement hélicoïdales. Il serait également possible d'avoir des rainures croisées selon deux hélices de sens opposés.Alternatively, the grooves could be oblique relative to the axis of the system, i.e. practically helical. It would also be possible to have grooves crossed according to two sense helices opposed.

On a vus, figure 4, que l'utilisation de deux rouleaux superposés permet d'augmenter localement la traction sur le tricot. La figure 6 montre comment il est possible d'augmenter localement la traction au moyen d'un seul rouleau. Ceci est possible en segmentant les bâtis, par exemple le bâti 12 représenté à la figure 6. Ce bâti est ici segmenté en plusieurs bâtis indépendants 12a à 12g. Au moyen d'un ou deux rouleaux, tels que les rouleaux 21 et 22, il est possible d'augmenter localement la tension de la courroie 5 sur un ou plusieurs des segments de bâti 12a à 12g. Le segment de bâti sur lequel agit cette surtension appliquera plus fortement la courroie contre la courroie opposée, augmentant ainsi la force de tirage. Un seul bâti ou les deux bâtis peuvent être segmentés.We saw, figure 4, that the use of two rollers superimposed locally increases traction on knitting. Figure 6 shows how it is possible locally increase traction with a single roller. This is possible by segmenting the frames, by example the frame 12 shown in Figure 6. This frame is here segmented into several independent frames 12a to 12g. By means of one or two rollers, such as rollers 21 and 22, it is possible to locally increase the voltage of the belt 5 on one or more of the segments of frame 12a to 12g. The frame segment on which this overvoltage will apply the belt more strongly against the opposite belt, thereby increasing the force of draw. A single frame or both frames can be segmented.

Le renvoi 10 est bien entendu également segmenté en plusieurs renvois 10a à 10g.The reference 10 is of course also segmented into several references 10a to 10g.

L'augmentation localisée de la pression, c'est-à-dire de la tension sur les courroies pourrait être obtenue par d'autres moyens que les rouleaux décrits.The localized increase in pressure, i.e. the tension on the belts could be obtained by other means than the rollers described.
