Definitions
- the invention relates to a straight knitting machine with a thread dispenser.
- Another knitting machine is described in the patent EP0526406 . It includes two needle beds whose associated cam holders are independent and have their own drive means in the form of belts. These drive means are mutually slaved to obtain the synchronization of the displacements of the two cam carriers.
- This solution therefore eliminates the clutter that was present above the needle beds because of the hoops used and thus has the advantage of allowing a feed of the son to the yarn distributors from above, so-called "direct threading" solution.
- each wire feeder has its own small electric motor to move on its bar-stripper. This solution therefore also increases the number of bars and tracks and therefore the number of wire distributors.
- a general object of the present invention is to provide a knitting machine which has the advantages of the solutions of the prior art without the disadvantages.
- a first object of the present invention is to provide a knitting machine that avoids shocks between the yarns during movement of the wire distributors.
- a second object of the present invention is to provide a knitting machine which allows an advantageous distribution of son.
- a third object of the present invention is to provide a knitting machine which allows the use of a large number of yarn dispensers.
- a fourth object of the present invention is to provide a simple and inexpensive knitting machine.
- the invention is based on a straight knitting machine comprising at least one yarn dispenser according to claim 1.
- the figure 1 represents a first embodiment of the invention wherein a wire feeder 1 comprises a shoe 2 and a spout 3, connected to the shoe 2 by a movable connection about an axis 4 of rotation.
- the yarn dispenser 1 is moved in the track 6 of a bar-stripper placed above the needle beds 50 of a knitting machine by a motor 5, mounted laterally, via a string 7 fixed from and the other of the pad 2 at points 9.
- the string 7 is driven by a shaft set in motion by the motor 5 and makes a round-trip over the entire length of the needle beds 50 around pulleys 8.
- a second string 10 is fixed at the spout 3 at a point 11 offset from the axis 4, linking the spout 3 and the pad 2, and also makes a round trip over the entire length of the needle bed around two longitudinal pulleys 12.
- a actuator 13 can occupy two stable positions, a first position shown in FIG. figure 1a in which it does not interact with the string 10 and a second position shown in FIG. figure 1b in which it clamps the string 10.
- the two strings 7 and 10 are positioned within the track 6 and their size is very small and does not affect the distribution of the wire.
- the spout-thread 3 is vertical and able to distribute a thread needle needles for knitting operations.
- the wire feeder 1 is driven by the motor 5 via the string 7 connected to the pad 2 to follow the movement of the cam carriage and distribute the wire to the activated needles.
- This movement of the thread distributor 1 induces the simultaneous movement of the spout 3 and the string 10 which is linked to it.
- the spout 3 maintains this vertical position by means of a locking device, not shown so as not to weigh down the diagram, which can rest for example on a spring or a ball screw.
- the yarn dispenser 1 When the yarn dispenser 1 is no longer used for knitting operations, it is stopped and put in its resting or parking or non-knitting configuration shown in FIG. figure 1b , in which the spout 3 occupies a new position relative to the pad 2 following a rotation in the direction of the arrow A around its axis 4.
- the actuator 13 pinches the string 10 while the motor 5 drives the string 7 and thus the pad 2 in the direction of the arrow B.
- the point 11 of the spout 3 is thus held fixed by the string 10 while the point 4 of the same spout-thread is moves longitudinally to the right in the direction of the arrow B.
- a symmetrical configuration (not shown) is provided when the wire feeder moves longitudinally towards the left in the opposite direction to the arrow B, before being stopped and put in rest configuration.
- the thread distributor is provided with a spring, not shown, which recalls the spout in its vertical position as soon as the actuator 13 releases the pinch . Once this position is found, the motor 5 can again move the operating wire dispenser for knitting.
- the return of the spout in its first position is achieved by a displacement to the left of the pad 2 while simultaneously pinching the string 10 by the actuator 13.
- a motor 5 has been used to cause displacement of the wire feeder but any other equivalent mechanism could be used.
- the string 7 may be connected by a pulley device to a driver device disposed in another bar-scratch located near the cam carriage and which could be driven by an actuating finger of the carriage itself, thus inducing at a distance the movement of the wire feeder placed on a parallel and further spreader bar.
- the motor 5 would therefore no longer be necessary but replaced by the motor of the carriage and using a more complex intermediate mechanism but not bulky and less expensive to allow this setting in motion at a distance.
- the concept of the invention consists on the one hand in carrying out all the movements of the yarn dispenser by a motor-type drive means, the relatively bulky part of which is placed in an area of the knitting machine where it does not interfere with the operation of dispensing the wire above the beds, by a lateral positioning for example according to the embodiment shown.
- This drive means is thus remote from the knitting zone and a simple and space-saving intermediate connection means of wire, string, cable, belt or any equivalent type is used to bind it to the wire feeder.
- this connecting means is a wire disposed in the track of the bar-stripper.
- the drive means performs two functions to achieve on the one hand a longitudinal movement of the yarn dispenser for the knitting operations and on the other hand a relative movement of the spout. thread relative to the yarn dispenser pad to clear the spout tip 3a when the yarn dispenser no longer participates in the knitting.
- the driving means consists of a motor 5 and an actuator 13 arranged longitudinally in the knitting machine, at the end of a bar-scaler, and the connecting means consists of two strings 7 and 10
- the driving means may consist of one or more devices, such as two motors for example, and the connecting means may also consist of one or more devices, wire, cable ( s), belt (s), rod (s), implementing in combination or separately its two functions mentioned above.
- the Figures 2a to 2c represent an embodiment that is not according to the invention.
- the figure 2a represents a wire distributor 1 in its knitting configuration, wherein the spout-thread 3 occupies a lower vertical position so as to be able to distribute a thread to the needles of the knitting machine.
- the yarn dispenser 1 comprises a shoe 2 movable in a track 6, a spout 3 connected to the shoe 2 by an intermediate element, the cam 14, disposed within a frame 17 of the shoe 2 so as to be able to slide by relative to the shoe 2 in a longitudinal direction (represented by the arrow B or its opposite direction).
- the element 14 comprises a slot 15 in the form of a circular arc and the spout 3 is connected to this cam movably by a pin 16 placed in the slot 15.
- the spout 3 is positioned in a channel 25 of the pad 2, which allows vertical movement only.
- the yarn dispenser 1 is moved via a driving device and by a cable 7 fixed to the element 14. This wire feeder driving device is not shown and is the same as the one used in the first execution mode.
- the thread distributor 1 moves longitudinally to the right in the direction of the arrow B under the effect of the driving means which pulls the cable 7 fixed at the connection point 9 to the intermediate element 14.
- the latter is located disposed in its most extreme position on the right in the frame 17, in contact with the wall of the pad 2, and will thus cause the latter in its movement.
- the pin 16 of the spout 3 occupies an extreme position on the left in the light 15 and is in its lowest position.
- the yarn dispenser 1 When the yarn dispenser 1 is no longer used for knitting, it is placed in its second configuration, illustrated in FIG. Figures 2b and 2c in which the spout 3 occupies a raised position which deviates from the knitting zone above the needle beds 50.
- the thread distributor is first stopped and then the drive means causes a slight displacement in the opposite direction to the arrow B of the intermediate element 14 so that it slides within the pad 2 to occupy a central position, with a stroke equal to half the width of the frame 17.
- the pin 16 of the spout-wire 3 moves in the light 15 to its highest central position on the arc circle.
- This movement is made possible because it imposes a friction between the pad 2 of the wire distributor and the track 6 greater than the friction between the pad 2 and the intermediate element 14, for example by ensuring a clearance between the latter two elements.
- This movement of the pin 16 upwards thus raises the whole of the spout 3 in its channel 25 and moves its tip 3a away from the knitting zone.
- the return to the operating position of the first configuration is achieved by a drive to the right or the left of the element 14.
- the element 14 moves within the pad 2 by driving the spout-wire 3 downwards through through the movement of the pin 16 in the light 15, until it reaches an extreme position in the frame 17 of the pad 2 in which it is in contact with the edge of the pad 2.
- the pad 2 remains stationary under the effect of the friction forces explained above.
- the knitting configuration is then reached.
- the element 14 always driven in the same direction at the same time drives the shoe 2.
- the element 14, the shoe 2 and the spout-wire 3 then remain motionless relative to each other and the tip of the spout-wire 3 is in the knitting position.
- a longitudinal stroke of the element 14 in the shoe 2 equivalent to that of the pin 16 in the light 15 is provided by the appropriate dimensions of the light 15 and the width of the light. frame 17 of the pad 2.
- more dimensions large ones can be chosen for the light 15 to allow the element 14 to possibly adapt to distributors of yarn of different geometry.
- the connecting means consists of a single cable 7.
- the Figures 3a to 3c illustrate an embodiment that is not according to the invention.
- the yarn dispenser 1 likewise comprises a shoe 2, an intermediate element 14 and a spout 3.
- the thread spout comprises a first pin 16a which passes through a first lumen 18 of the shoe 2 and a second lumen 15 in an arc. of the intermediate element 14. It comprises a second pin 16b passing through the slot 18 of the pad 2.
- the two pins 16a and 16b only allow vertical movement of the spout 3 relative to the pad 2.
- the yarn dispenser is moved by via a drive means not shown, and by a string 7 fixed in this variant to the connection point 9 on the pad 2 and no longer on the intermediate element 14.
- the latter is mounted longitudinally movable within the track 6 of the strip-bar and moves relative to the pad 2 between two extreme positions defined by the two longitudinal stops 19 of the pad 2.
- the intermediate element 14 is positioned in its extreme position to the left with respect to the pad 2, which moves to the right under the effect of the drive means which pulls the string 7 to the right in the direction of the arrow B.
- the pin 16a of the spout 3 then occupies its lowest position in the two lumens 15 and 18 and likewise, the pin 16b occupies its lowest position within the lumen 18.
- the return to the knitting configuration is the same by a longitudinal drive of the pad 2, which leads in a first time the spout-yarn down and then the whole of the yarn dispenser to the needles selected for knitting.
- FIGS. 4a to 4c illustrate an embodiment of the invention. It differs in that the shoe 2 and the intermediate element 14 are both connected to the drive means by respectively two belts 7 and 10.
- the belt 7 is driven by a motor 5 and a drive shaft 8.
- the link between the drive means and the wire feeder comprises four connection points 9.
- the Figures 4a and 4b represent the knitting configuration of the yarn dispenser 1, in which the drive shaft 8 is integral with a pulley 12 of the same diameter, held in this stable position by the force of a spring 20, which drives the belt 10 so synchronized with the belt 7.
- the pad 2 and the intermediate element 14 are driven at the same speed and in the same direction and remain immobile with respect to each other, the spout-thread 3 thus remaining in its lowest operational position.
- the actuator 13 pushes the pulley 12 down against the force of the spring 20 and disengages it from the drive shaft 8, in the manner of a clutch.
- the belt 10 is stopped.
- the motor 5 continues slightly to drive the shoe 2 through the belt 7 until the intermediate element 14 has slid into the frame 17 of the shoe 2 to its extreme position against the wall of the shoe, causing at the same time the displacement of the pin 16 within the lumen 15 and the upward vertical movement of the spout 3 within the channel 25 of the pad 2.
- the repositioning of the dispenser in knitting configuration will therefore be done by a first light drive of the shoe 2 on a stroke equal to half the width of its frame 17, to refocus the intermediate element 14 and to lower at the same time the Next, the actuator 13 releases the pulley 12 which fits again in the motor shaft 8 and returns to the configuration illustrated by FIG. figure 4a .
- the wire feeder 1 comprises a pad 2, connected to a drive means 5 not shown by means of a cable 7, an intermediate element 14 and a spout-wire 3.
- the intermediate member 14 comprises an end 20 in contact with the track 6, an axis 21 passing through the pad 2 through an opening 22 which defines a axis of rotation of the intermediate element 14, then a circular portion 23 off-axis with respect to the axis 21 and placed in an oblong slot 24 of the spout-wire 3.
- the latter is also maintained in a channel 25 of the skid 2 allowing only its vertical movement.
- FIGS. 5a and 5b illustrate the yarn dispenser 1 in the knitting configuration.
- the shoe 2 is driven to the right, the intermediate element 14 occupies a position turned to the left of 45 degrees about its axis of rotation 21, its circular portion being in abutment against the left edge of the oblong slot 24 and the spout-thread occupies its lowest position.
- FIGS. 5c and 5d illustrate the second configuration of the wire feeder 1 in the rest position, the spout 3 being raised.
- the passage in this configuration is achieved by stopping the drive of the wire feeder and driving it in opposite directions on a small stroke to cause the movement of the pad to the left, causing simultaneously the rotation of the intermediate element 14 around its axis 21 until it reaches its vertical position.
- the spout is simultaneously raised.
- the operating principle is of the eccentric rotation type.
- the wire feeder 1 comprises a shoe 2, connected to a drive means not shown by means of a not shown belt, a spur 3 connected to the shoe by a connection 25. allowing it a relative vertical displacement.
- the spout 3 comprises a pin 16 positioned on a rod 27 connected to a bi-stable actuator 28 positioned longitudinally, which allows the rod to be able to occupy two stable positions, a low position shown in FIGS. Figures 6a and 6b wherein the spout 3 occupies its lowest position in the knitting mode and a high position shown in FIGS. Figures 6c and 6d in which it occupies a high position, remote from the knitting zone.
- a motor 28 may be used, allowing the rod to occupy more than two different positions.
- the drive means is composed of two separate devices to fulfill the two displacement functions independently.
- the connecting means consists of two distinct means.
- the motor 28 is dedicated to the vertical displacement of the spout 3 relative to the pad 2 by means of a clean connecting means which is a rod 27, connected to the spout-wire 3 in a single contact 9.
- the Longitudinal displacement of the wire feeder is achieved by a motor connected to the pad by a cable, these means not being represented.
- the Figures 7a, 7b and 8 illustrate an embodiment of the invention, wherein the strip-bar comprises two superimposed tracks 6a and 6b respectively receiving the pad 2 and the intermediate element 14, respectively connected by belts 7 and 10 to motors 5a and 5b .
- the two tracks 6a and 6b could be on either side of the same bar-strip, or even on two different bar-stripers.
- the spout 3 consists of a first rigid element 3b supporting the spike 3a, illustrated in FIG. figure 8 , and a superimposed blade 3c.
- This blade 3c is on the one hand connected to the intermediate element 14 by a pin 16a passing through a vertical slot 30 of the first element 3b and a cam path 31 of the intermediate element 14 and secondly connected to the pad 2 by two pins 16b and 16c passing through a vertical light 18 of the shoe 2 and a vertical light of the element 3b.
- the latter is thus bound by these pins 16a, 16b and 16c in a movable connection vertically relative to the pad 2.
- It is further connected to the intermediate element 14 via a pin 26 passing through a second cam path 32 of this element 14.
- the figure 7a illustrates the knitting configuration in which the intermediate element 14 and the shoe 2 are at the same level in their respective longitudinal position on the tracks 6b and 6a. This corresponds to the lowest position of the pin 26 of the element 3b in the cam path 32, and therefore induces the lowest position of the tip 3a of the knitting yarn 3 suitable for knitting. Note that the blade 3c occupies a raised position, its pin 16a being in the upper part of the cam path 31. This respective position of the element 3b and the blade 3c corresponds to the figure 8 and will be explained below.
- the figure 7b illustrates an intermediate configuration between that of knitting of the figure 7a and the rest configuration, not shown.
- the passage in this intermediate configuration is achieved by a shift of the intermediate member 14 relative to the pad 2 on their respective tracks 6b and 6a through the respective two motors 5b and 5a.
- the pin 26 of the element 3b occupies a higher position in the cam path 32 and begins to raise the tip 3a of the spout-yarn away from the knitting zone.
- the blade 3c occupies a low position relative to the element 3b.
- the figure 8 illustrates the lower part of the spout 3 in its knitting configuration.
- the first element 3b of the spout comprises a guide 35 for the thread 40, comprising two protuberances 36a and 36b.
- the blade 3c passes through this guide 35 and forms a loop 37 oriented towards the protuberances 36, thus forming a chicane-type circuit for the knitting yarn 40.
- the loop 37 approaches one of the protuberances 36, which causes an increase in friction on the wire 40 and the increase of its voltage.
- the loop 37 has moved closer to the protuberance 36a.
- This function of braking or variation of the tension of the thread is particularly useful in the field of orthopedics for which products are knitted using an eraser. In this type of application, it is necessary, especially when parking the rubber dispenser, to keep the rubber under tension. It is also suitable for knitting from an elastic yarn.
- the means used have a symmetry to allow to obtain an identical result irrespective of the direction of movement of the wire feeder, from left to right or vice versa.
- Such a result can be envisaged with a combination of non-symmetrical elements but with different relative motions.
- the spout 3 has been simplified into a single element for the sake of clarity but may alternatively consist of several elements.
- it may consist of a first rigid portion attached to the pad, serving as a support for a softer and lighter, movable part, which includes the tip of the spout-yarn.
- the movement of the spout may consist of a movement of a light element at the tip of the spout, this movement being transmitted by other elements of the spout-thread positioned towards the pad.
- the invention may also be applied to a yarn dispenser comprising a plurality of spouts, or a yarn spout comprising a plurality of spikes, able to move simultaneously or independently of each other to be clear of the knitting zone.

Description
L'invention concerne une machine à tricoter rectiligne avec un distributeur de fil.The invention relates to a straight knitting machine with a thread dispenser.
Les machines à tricoter traditionnelles, telles que décrites dans le brevet
- le cheminement d'un fil depuis une bobine jusqu'au distributeur de fil est complexe et chaque fil est soumis à des tensions, frottements et torsions importants qui provoquent des usures prématurées du fil, des déformations des mailles, voire des cassures du fil qui provoquent l'arrêt de la machine. Les fils délicats sont très difficiles à tricoter ;
- cette distribution horizontale du fil vers le distributeur de fil entraîne une dissymétrie du fonctionnement de la machine ;
- les contraintes précédentes limitent la vitesse de déplacement du chariot porte-cames et donc le rendement de la machine ;
- le nombre maximal de distributeurs de fil possibles est limité puisque leur positionnement s'effectue dans un volume réduit entre la fonture et les arceaux du chariot porte-cames. D'autre part, la complexité de l'alimentation des fils vers ces distributeurs de fil limite aussi leur nombre. Or, pour obtenir des possibilités de tricotage variées, il est nécessaire d'avoir un nombre important de fils et donc de distributeurs de fil à disposition ;
- les dispositifs de sélection et d'entraînement des distributeurs de fil subissent des déplacements rapides et permanents et de nombreux à-coups, ce qui augmente leur usure et réduit leur durée de vie. Ils nécessitent de plus une alimentation électrique, ce qui est complexe puisqu'ils se déplacent en permanence sur toute la longueur de la machine à tricoter.
- the path of a wire from a coil to the wire feeder is complex and each wire is subjected to high voltages, friction and twisting which cause premature wear of the wire, deformation of the meshes, or even breaks in the wire which cause stopping the machine. The delicate yarns are very difficult to knit;
- this horizontal distribution of the wire towards the distributor of wire causes a dissymmetry of the operation of the machine;
- the previous constraints limit the speed of displacement of the cam carriage and thus the efficiency of the machine;
- the maximum number of possible wire distributors is limited since their positioning takes place in a reduced volume between the needle bed and the arches of the cam carriage. On the other hand, the complexity of feeding the wires to these wire distributors also limits their number. However, to obtain various knitting possibilities, it is necessary to have a large number of son and therefore wire distributors available;
- wire feeder selection and drive devices experience rapid and permanent movement and many jolts, which increases wear and shortens their life. They also require a power supply, which is complex since they move permanently along the entire length of the knitting machine.
Dans ces machines à tricoter traditionnelles, un mécanisme est souvent prévu pour dégager un bec-fil de la zone à tricoter quand il n'est plus utilisé. Pour cela, certains dispositifs comme celui décrit dans le document
Une autre machine à tricoter est décrite dans le brevet

Dans les différents modes d'exécution, les mêmes références seront utilisées pour les mêmes moyens ou des moyens équivalents.In the different embodiments, the same references will be used for the same means or equivalent means.

Lorsque le distributeur de fil 1 n'est plus utilisé pour des opérations de tricotage, il est stoppé et mis dans sa configuration de repos ou de stationnement ou de non tricotage représentée à la
De manière évidente, une configuration symétrique non représentée est prévue quand le distributeur de fil se déplace longitudinalement vers la gauche dans le sens opposé à la flèche B, avant d'être stoppé et mis en configuration de repos.Obviously, a symmetrical configuration (not shown) is provided when the wire feeder moves longitudinally towards the left in the opposite direction to the arrow B, before being stopped and put in rest configuration.
Pour le passage de la seconde configuration de la
Dans le cas de la variante selon laquelle le bec-fil est maintenu dans cette seconde position par un mécanisme de verrouillage, à l'aide d'une vis à bille par exemple, le retour du bec-fil dans sa première position est réalisé par un déplacement vers la gauche du patin 2 tout en pinçant simultanément la ficelle 10 par l'actuateur 13.In the case of the variant in which the spout is held in this second position by a locking mechanism, using a ball screw for example, the return of the spout in its first position is achieved by a displacement to the left of the
Dans ce premier mode d'exécution de l'invention, un moteur 5 a été utilisé pour provoquer le déplacement du distributeur de fil mais tout autre mécanisme équivalent pourrait être utilisé. Par exemple, la ficelle 7 pourra être reliée par un dispositif de poulies à un dispositif entraîneur disposé dans une autre barre-rayeur située à proximité du chariot porte-cames et qui pourrait être entraîné par un doigt d'actionnement du chariot lui-même, induisant ainsi à distance le mouvement du distributeur de fil placé sur une barre-rayeur parallèle et plus éloignée. Le moteur 5 ne serait donc plus nécessaire mais remplacé par le moteur du chariot et utilisant un mécanisme intermédiaire plus complexe mais peu encombrant et moins coûteux pour permettre cette mise en mouvement à distance.In this first embodiment of the invention, a
Finalement, le concept de l'invention consiste d'une part à réaliser tous les mouvements du distributeur de fil par un moyen d'entraînement de type moteur, dont la partie relativement encombrante par nature est placée dans une zone de la machine à tricoter où elle ne gêne pas l'opération de distribution du fil au-dessus des fontures, par un positionnement latéral par exemple selon le mode d'exécution représenté. Ce moyen d'entraînement est donc éloigné de la zone de tricotage et un moyen de liaison intermédiaire simple et peu encombrant de type fil, ficelle, câble, courroie ou tout équivalent est utilisé pour le lier au distributeur de fil. Dans le mode d'exécution représenté, ce moyen de liaison est un fil disposé dans la piste de la barre-rayeur. D'autre part, selon le concept de l'invention, le moyen d'entraînement remplit deux fonctions pour réaliser d'une part un déplacement longitudinal du distributeur de fil pour les opérations de tricotage et d'autre part un déplacement relatif du bec-fil par rapport au patin du distributeur de fil afin de dégager la pointe 3a du bec-fil quand le distributeur de fil ne participe plus au tricotage.Finally, the concept of the invention consists on the one hand in carrying out all the movements of the yarn dispenser by a motor-type drive means, the relatively bulky part of which is placed in an area of the knitting machine where it does not interfere with the operation of dispensing the wire above the beds, by a lateral positioning for example according to the embodiment shown. This drive means is thus remote from the knitting zone and a simple and space-saving intermediate connection means of wire, string, cable, belt or any equivalent type is used to bind it to the wire feeder. In the embodiment shown, this connecting means is a wire disposed in the track of the bar-stripper. On the other hand, according to the concept of the invention, the drive means performs two functions to achieve on the one hand a longitudinal movement of the yarn dispenser for the knitting operations and on the other hand a relative movement of the spout. thread relative to the yarn dispenser pad to clear the

Dans la configuration de tricotage représentée à la
Lorsque le distributeur de fil 1 n'est plus utilisé pour le tricotage, il est placé dans sa deuxième configuration, illustrée en
Le retour en position de fonctionnement de la première configuration est réalisé par un entraînement vers la droite ou la gauche de l'élément 14. L'élément 14 se déplace au sein du patin 2 en entraînant le bec-fil 3 vers le bas, par le biais du déplacement de la goupille 16 dans la lumière 15, jusqu'à ce qu'il atteigne une position extrême dans le cadre 17 du patin 2 dans laquelle il est en contact avec le bord du patin 2. Pendant cette phase, le patin 2 reste immobile sous l'effet des forces de frottement explicitées ci-dessus. La configuration de tricotage est alors atteinte. Ensuite, l'élément 14 toujours entraîné dans la même direction entraîne en même temps le patin 2. L'élément 14, le patin 2 et le bec-fil 3 restent alors immobiles les uns par rapport aux autres et la pointe du bec-fil 3 est en position de tricotage.The return to the operating position of the first configuration is achieved by a drive to the right or the left of the
Pour obtenir l'effet décrit ci-dessus, il est prévu une course longitudinale de l'élément 14 au sein du patin 2 équivalente à celle de la goupille 16 dans la lumière 15 grâce aux dimensionnements adaptés de la lumière 15 et de la largeur du cadre 17 du patin 2. En variante, des dimensions plus grandes peuvent être choisies pour la lumière 15 pour permettre à l'élément 14 de s'adapter éventuellement à des distributeurs de fil de géométrie différente.To obtain the effect described above, a longitudinal stroke of the
Dans ce second mode d'exécution, le moyen de liaison se compose d'un seul câble 7.In this second embodiment, the connecting means consists of a

Lorsque ce distributeur de fil n'est plus utilisé, il est stoppé puis le moyen d'entraînement 5 déplace le patin 2 dans le sens opposé à la flèche B. Ce déplacement provoque le glissement du patin 2 par rapport à l'élément intermédiaire 14, qui est stoppé quand cet élément intermédiaire occupe sa position centrale. Dans le même temps, la goupille 16a se déplace jusqu'à sa position la plus haute dans les lumières 15 et 18, comme illustré sur les
Le retour en configuration de tricotage se fait de même par un entraînement longitudinal du patin 2, qui entraîne dans un premier temps le bec-fil vers le bas puis l'ensemble du distributeur de fil jusqu'aux aiguilles sélectionnées pour le tricotage.The return to the knitting configuration is the same by a longitudinal drive of the

Pour provoquer le passage du bec-fil 3 dans la configuration de repos de la
Le repositionnement du distributeur en configuration de tricotage se fera donc par un premier léger entraînement du patin 2 sur une course égale à la moitié de la largeur de son cadre 17, permettant de recentrer l'élément intermédiaire 14 et de redescendre dans le même temps le bec-fil 3. Ensuite, l'actionneur 13 libère la poulie 12 qui s'emboîte de nouveau dans l'arbre moteur 8 et permet de revenir à la configuration illustrée par la

Dans ce mode d'exécution, le moyen d'entraînement se compose de deux dispositifs distincts pour remplir les deux fonctions de déplacement de manière indépendante. De même, le moyen de liaison se compose de deux moyens distincts. En effet, le moteur 28 est dédié au déplacement vertical du bec-fil 3 relativement au patin 2 par l'intermédiaire d'un moyen de liaison propre qui est une tringle 27, reliée au bec-fil 3 en un simple contact 9. Le déplacement longitudinal du distributeur de fil est réalisé par un moteur relié au patin par un câble, ces moyens n'étant pas représentés. Un avantage de cette séparation et distinction totale des fonctions d'entraînement est de permettre une souplesse d'utilisation optimale, le bec-fil 3 pouvant être déplacé verticalement à tout moment pendant le déplacement longitudinal du distributeur de fil 1.In this embodiment, the drive means is composed of two separate devices to fulfill the two displacement functions independently. Likewise, the connecting means consists of two distinct means. Indeed, the

Le bec-fil décrit précédemment met donc en oeuvre cette fonction de freinage du fil par le biais d'une lame mobile verticalement par rapport au reste du bec-fil, ce mouvement vertical étant directement combiné à celui de mise en stationnement du bec-fil. Ce mouvement respectif des deux éléments 3b et 3c du bec-fil est défini par la forme des chemins de came 31 et 32. Comme cela est illustré à titre d'exemple sur les
- le freinage du fil lors du tricotage, pour une application particulière qui nécessiterait de tendre ce fil pendant le tricotage ;
- le freinage et pincement du fil uniquement lorsque le bec-fil se trouve en position de repos ou de non tricotage.
- the braking of the yarn during knitting, for a particular application that would require stretching the yarn during knitting;
- braking and pinching of the yarn only when the yarn nose is in the rest or non-knitting position.
Comme les mouvements de l'élément intermédiaire 14 et du patin 2 sont réalisés par un moyen d'entraînement comprenant deux moteurs 5a et 5b indépendants, leur positionnement respectif peut être modifié de manière dynamique lors du travail de la distribution du fil pendant l'opération de tricotage, afin de mettre en oeuvre les fonctions de tension du fil et/ou de mise en repos.As the movements of the
Cette fonction de freinage ou de variation de la tension du fil est particulièrement utile dans le domaine de l'orthopédie pour lequel des produits sont tricotés à l'aide d'une gomme. Dans ce type d'application, il est nécessaire, notamment lors d'une mise en stationnement du distributeur de gomme, de maintenir cette gomme sous tension. Elle convient aussi au tricotage à partir d'un fil élastique.This function of braking or variation of the tension of the thread is particularly useful in the field of orthopedics for which products are knitted using an eraser. In this type of application, it is necessary, especially when parking the rubber dispenser, to keep the rubber under tension. It is also suitable for knitting from an elastic yarn.
Dans les différents modes de réalisation précédents, les moyens mis en oeuvre possèdent une symétrie afin de permettre d'obtenir un résultat identique quel que soit le sens de déplacement du distributeur de fil, de gauche à droite ou inversement. Un tel résultat peut être envisagé avec une combinaison d'éléments non symétriques mais avec des mouvements relatifs différents.In the various previous embodiments, the means used have a symmetry to allow to obtain an identical result irrespective of the direction of movement of the wire feeder, from left to right or vice versa. Such a result can be envisaged with a combination of non-symmetrical elements but with different relative motions.
Dans des modes d'exécution, le bec-fil 3 a été simplifié en un seul élément pour des raisons de clarté mais il peut en variante se composer de plusieurs éléments. Par exemple, il peut se composer d'une première partie rigide, fixée au patin, servant de support à une partie plus souple et plus légère, mobile, qui comprend la pointe du bec-fil. Le mouvement de dégagement du bec-fil peut donc consister en un mouvement d'un élément léger à la pointe du bec-fil, ce mouvement étant transmis par d'autres éléments du bec-fil positionnés vers le patin.In embodiments, the
L'invention peut aussi être appliquée à un distributeur de fil comprenant plusieurs bec-fils, ou un bec-fil comprenant plusieurs pointes, pouvant bouger simultanément ou indépendamment les unes des autres pour être dégagées de la zone de tricotage.The invention may also be applied to a yarn dispenser comprising a plurality of spouts, or a yarn spout comprising a plurality of spikes, able to move simultaneously or independently of each other to be clear of the knitting zone.
Les variantes précédentes ont décrit des solutions pour dégager la pointe d'un bec-fil d'une zone de tricotage au-dessus des fontures par un mouvement de rotation ou de remontée verticale. Toutefois, le principe de l'invention pourrait être repris pour tout autre type de mouvement de la pointe du bec-fil par rapport aux fontures, provoquant son dégagement de la zone de tricotage, par exemple par des chemins de came de formes différentes pour les adapter à des situations particulières. De plus, les différents éléments des différents modes d'exécution décrits, comme le moyen d'entraînement, le moyen de liaison, la liaison mécanique entre le patin et le bec-fil, pourraient être combinés pour aboutir à d'autres modes d'exécution.The above variants have described solutions for clearing the tip of a spout-yarn of a knitting zone above the needle beds by a rotational movement or vertical lift. However, the principle of the invention could be taken over for any other type of movement of the tip of the spout with respect to the needle beds, causing its release from the knitting zone, for example by cam paths of different shapes for the adapt to particular situations. In addition, the various elements of the different embodiments described, such as the drive means, the connecting means, the mechanical connection between the pad and the spout, could be combined to lead to other modes of operation. execution.
Finalement, la solution selon l'invention atteint bien les objets recherchés et présente de nombreux avantages parmi lesquels :
- elle permet un dégagement de la pointe des bec-fils en repos afin d'éviter leur frottement, choc et gêne avec un autre bec-fil en opération de tricotage et/ou avec les aiguilles en ascension ;
- elle permet une distribution avantageuse des fils à tricoter par le haut, par un encombrement minimal du volume situé au-dessus des fontures. Le dernier mode d'exécution permet en outre une amélioration supplémentaire de la distribution du fil par la maîtrise de sa tension ;
- elle peut être implémentée avec un grand nombre de distributeurs de fil ;
- elle est simple et peu coûteuse.
- it allows a release of the tips of the spouts-son in rest in order to avoid their friction, shock and discomfort with another spout in knitting operation and / or with the needles in ascension;
- it allows an advantageous distribution of the knitting yarns from above, by a minimum space requirement of the volume located above the needle beds. The last execution mode also allows a further improvement of the yarn distribution by controlling its tension;
- it can be implemented with a large number of wire distributors;
- it is simple and inexpensive.
