Description
L'invention concerne le domaine technique des installations ou machines de transformation de matières allongées continues mises en mouvement par l'effet de défilement le long de leur propre trajectoire. Parmi les matières allongées continues, on peut citer les fils textiles, les rubans, les bandes, ...The invention relates to the technical field of installations or machines for converting continuous elongated materials set in motion by the scrolling effect along their own trajectory. Among the continuous elongated materials, mention may be made of textile threads, ribbons, strips, etc.
Plus particulièrement, l'invention concerne le pilotage des moyens de mise en mouvement de la matière apte à la faire avancer le long de sa propre trajectoire. Parmi ces moyens, on peut citer à titre indicatif nullement limitatif des cylindres, poulies, bandes sans fin, galets, godets ou autres organes entraînant la matière allongée par friction, pincement, effet d'engrènement, ...More particularly, the invention relates to controlling the means for moving the material capable of moving it along its own trajectory. Among these means, mention may be made, by way of non-limiting example, of rolls, pulleys, endless belts, rollers, buckets or other members driving the elongated material by friction, pinching, meshing effect, etc.
Différentes solutions techniques ont été proposées pour le démarrage d'une installation de machine destinée à la transformation de matières allongées ou autres produits filiformes. Selon l'état antérieur de la technique, on distingue essentiellement deux solutions.Various technical solutions have been proposed for starting a machine installation intended for the processing of elongated materials or other filiform products. According to the prior art, there are essentially two solutions.
Selon une première solution (
A l'inverse de cette solution, une autre méthode consiste à démarrer préalablement les organes de mise en mouvement de la matière et de les porter à la vitesse nominale puis à engager ladite matière. C'est seulement lorsque la vitesse nominale est atteinte que la matière est introduite à l'entrée des organes de mise en mouvement, de sorte que la matière est happée et portée instantanément à la vitesse nominale. Généralement, la matière est présentée par un dispositif qui lui confère une vitesse initiale proche de la vitesse nominale du procédé de traitement. Par exemple, ce dispositif peut être constitué par des bras associés à des buses d'aspiration telles que celles couramment utilisées dans le domaine des machines textiles.
Cette solution est toutefois difficilement applicable dans le cas de procédés à haute vitesse de matières fragiles qui ne supportent pas des accélérations brutales, généralement au moment où la matière est happée.
Lorsque l'opération est réalisée manuellement, elle exige une grande habileté de la part de l'opérateur.
On note également des problèmes de sécurité étant donné que les opérations sont effectuées sur des organes en mouvement.In contrast to this solution, another method is to start the moving bodies of the material beforehand and to bring them to the nominal speed then to engage said material. It is only when the nominal speed is reached that the material is introduced at the entry of the moving members, so that the material is snapped up and brought instantly to the nominal speed. Generally, the material is presented by a device which gives it an initial speed close to the nominal speed of the treatment process. For example, this device may consist of arms associated with suction nozzles such as those commonly used in the field of textile machines.
This solution is, however, difficult to apply in the case of high speed processes of fragile materials that do not withstand sudden accelerations, usually when the material is snapped.
When the operation is performed manually, it requires great skill on the part of the operator.
There are also safety issues as operations are performed on moving bodies.
Enfin, on a proposé, dans certaines installations complexes, de combiner les deux solutions techniques préalablement exposées d'enfilage (
Là encore, la mise en oeuvre de cette solution est relativement délicate.Finally, it has been proposed, in some complex installations, to combine the two technical solutions previously exposed threading (
Here again, the implementation of this solution is relatively delicate.
L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
Le problème que se propose de résoudre l'invention est de piloter des organes de mise en mouvement des fils textiles pendant la phase de démarrage et le long de leur propre trajectoire.The problem to be solved by the invention is to control the organs for moving the textile threads during the start-up phase and along their own trajectory.
Selon l'invention, il a été conçu un procédé de pilotage des organes d'entraînement linéaire d'un fil textile pendant la phase de démarrage, chacun desdits organes étant assujetti à un moteur électrique, le moteur étant associé à au moins une unité de pilotage apte à recevoir des consignes de vitesse et/ou de rapport de vitesse et des ordres de démarrage/arrêt.According to the invention, it has been conceived a method for controlling the linear drive members of a textile thread during the start-up phase, each of said members being subjected to an electric motor, the motor being associated with at least one unit of control capable of receiving speed and / or speed reports and start / stop commands.
Selon l'invention, compte tenu du problème posé à résoudre :
- on assujettit l'unité de pilotage de l'organe à un moyen de mesure de vitesse dudit organe ;
- quand on reçoit un ordre de démarrage, on ne déclenche pas le démarrage du moteur si la vitesse mesurée est nulle ;
- on surveille l'information représentative de la vitesse mesurée de l'organe d'entraînement ;
- on enclenche une séquence de pilotage susceptible d'entraîner la mise en rotation du moteur, selon un profil de mise en vitesse préprogrammé lorsque l'on détecte une rotation provoquée par une intervention extérieure.
- the steering unit of the member is secured to a means for measuring the speed of said member;
- when we receive a start command, we do not start the engine if the measured speed is zero;
- information representative of the measured speed of the drive member is monitored;
- a piloting sequence is started which can cause the engine to be rotated, according to a pre-programmed speed-up profile when a rotation caused by an external intervention is detected.
Compte tenu des caractéristiques à la base de l'invention, il en résulte que le mode de démarrage ne peut être enclenché que lorsque le moteur est initialement à l'arrêt. Le basculement de ce mode de fonctionnement ne déclenche pas de séquence de pilotage du moteur de nature à occasionner sa mise en rotation immédiate selon un profil d'accélération. Tout au contraire, selon l'invention, le basculement dans ce mode de fonctionnement peut éventuellement, si la technologie du moteur le permet, provoquer la création d'un couple limité de maintien à l'arrêt. Ce couple peut être paramétrable et contrôlé par une limitation de la tension ou du courant par exemple.Given the basic characteristics of the invention, it follows that the start mode can be engaged only when the engine is initially stopped. Failover of this operating mode does not trigger an engine control sequence likely to cause its immediate rotation according to an acceleration profile. On the contrary, according to the invention, the switchover in this mode of operation can possibly, if the engine technology allows, cause the creation of a limited torque of holding at a standstill. This torque can be parameterized and controlled by a limitation of the voltage or the current for example.
Aussi longtemps qu'une rotation provoquée par une intervention extérieure n'est pas détectée, l'arrêt du moteur est maintenu.As long as a rotation caused by an outside intervention is not detected, the stopping of the engine is maintained.
Lorsqu'une rotation provoquée par une intervention extérieure est détectée, on enclenche la séquence de pilotage du moteur de nature à provoquer sa mise en rotation selon un profil de mise en vitesse programmée.When a rotation caused by an external intervention is detected, it activates the motor control sequence likely to cause it to rotate according to a programmed speed setting profile.
Selon un mode de réalisation préféré de l'invention, lorsqu'une rotation provoquée par l'intervention extérieure est détectée, on contrôle une information représentative du sens de rotation de l'organe d'entraînement, et l'on enclenche la séquence de pilotage du moteur de nature à provoquer sa mise en rotation seulement si le sens de rotation est conforme à un sens de rotation prédéterminé. En cas de détection d'un sens de rotation non-conforme, le système peut, si la technologie du moteur le permet, provoquer la création d'un couple résistant, ce couple pouvant être paramétrable et/ou contrôlé par une limitation de la tension ou du courant par exemple.
Suite à la réception d'un ordre de démarrage, le processus comprend :
- une période pendant laquelle le moteur est maintenu à l'arrêt ;
- une période pendant laquelle la rotation et provoquée par l'action extérieure ;
- une période pendant laquelle la mise en rotation suit le profil de mise en vitesse ; et
- une période de fonctionnement à vitesse nominale.
Following receipt of a start order, the process includes:
- a period during which the engine is kept at a standstill;
- a period during which rotation and caused by external action;
- a period during which the rotation follows the velocity profile; and
- a period of operation at nominal speed.
Selon l'invention, l'intervention extérieure est constituée par l'entraînement du fil et/ou de l'organe d'entraînement, ledit entraînement étant réalisé manuellement par un opérateur ou par des moyens auxiliaires.According to the invention, the external intervention is constituted by the drive of the wire and / or the drive member, said drive being performed manually by an operator or by auxiliary means.
Le profil de mise en vitesse préprogrammée est une rampe linéaire ou de forme quelconque.The preprogrammed speed profile is a linear ramp or of any shape.
Selon l'invention, le profil de mise en vitesse peut comporter un plateau à vitesse intermédiaire constante, différente de la consigne de vitesse nominale :
- La vitesse intermédiaire du plateau peut être préprogrammée.
- La vitesse intermédiaire du plateau peut être la vitesse de rotation créée par l'intervention extérieure et mesurée par l'unité de pilotage pendant quelques instants après sa détection.
- La durée de ce plateau peut être préprogrammée.
- Le plateau de vitesse peut être maintenu jusqu'à ce que l'unité de pilotage reçoive par une entrée/sortie ou par un réseau, un ordre de mise en vitesse.
- The intermediate speed of the tray can be preprogrammed.
- The intermediate speed of the plate can be the speed of rotation created by the external intervention and measured by the control unit for a few moments after its detection.
- The duration of this tray can be preprogrammed.
- The speed plateau can be maintained until the control unit receives an input / output or a network, an order of speeding.
Selon l'invention, cette séquence de pilotage détermine une limitation de couple (moteur ou frein), contrôlé par exemple par une limitation de la tension ou du courant :
- Cette limitation du couple peut être fixe.
- Cette limitation du couple peut dépendre de la vitesse de rotation.
- Cette limitation du couple peut être maintenue pendant un temps préprogrammé.
- Cette limitation du couple peut être maintenue jusqu'à ce que la vitesse atteigne la vitesse du plateau de vitesse intermédiaire.
- Cette limitation du couple peut être maintenue jusqu'à la fin du plateau de vitesse intermédiaire.
- Cette limitation du couple peut être maintenue jusqu'à ce que la vitesse atteigne la consigne de vitesse nominale.
- This limitation of the torque can be fixed.
- This limitation of the torque can depend on the speed of rotation.
- This torque limitation can be maintained for a preprogrammed time.
- This torque limitation can be maintained until the speed reaches the speed of the intermediate speed plateau.
- This torque limitation can be maintained until the end of the intermediate speed plateau.
- This torque limitation can be maintained until the speed reaches the nominal speed setpoint.
Pour la mise en oeuvre du procédé selon l'invention, le dispositif comprend des organes d'entraînement du fil textile chacun desdits organes étant assujetti à un moteur électrique, le moteur étant associé à au moins une unité de pilotage apte à recevoir des consignes de vitesse et/ou de rapport de vitesse et des ordres de démarrage/arrêt; le moteur étant à réluctance variable ou à aimants permanents et dont la séquence d'alimentation est une séquence de commutation des alimentations des bobinages synchronisées par des signaux représentatifs de la position du rotor par rapport au stator obtenus par des capteurs, lesdits signaux desdits capteurs étant envoyés dans un processeur pour mesurer et détecter la vitesse de rotation.For the implementation of the method according to the invention, the device comprises textile thread drive members each of said members being secured to an electric motor, the motor being associated with at least one control unit adapted to receive instructions from speed and / or speed ratio and start / stop commands; the motor being variable reluctance or permanent magnet and whose power supply sequence is a switching sequence of the windings power supplies synchronized by signals representative of the rotor position with respect to the stator obtained by sensors, said signals of said sensors being sent to a processor for measuring and detecting the speed of rotation.
Des moteurs à réluctance variable ou à aimants permanents pour le mouvement d'un fil sont connus du
Selon l'invention, chaque organe d'entraînement dispose d'un mode d'accompagnement au démarrage individuel, et de moyens d'attente de mise en rotation par une intervention extérieure pour accélérer selon son propre profil de mise en vitesse.According to the invention, each drive member has an individual start-up support mode, and rotation waiting means by an external intervention to accelerate according to its own speed setting profile.
La détection de la vitesse provoquée par une intervention extérieure, la gestion des profils de mise en vitesse, et plus généralement l'exécution de la séquence d'accompagnement est réalisée par un programme exécuté par une unité centrale et/ou par le processeur.The detection of the speed caused by an external intervention, the management of speeding profiles, and more generally the execution of the accompanying sequence is performed by a program executed by a central unit and / or by the processor.

On a illustré à la
Selon l'invention, le processeur (6) reçoit, de l'unité centrale (9) par le réseau, les consignes de vitesse ou rapport de vitesse, ainsi que les paramètres de fonctionnement des organes de mise en mouvement (1) pilotés par les moteurs (2). Eventuellement, le processeur (6) peut recevoir des ordres de démarrage, arrêt, ..., par le réseau ou par d'autres entrées/sorties.According to the invention, the processor (6) receives, from the central unit (9) by the network, the speed or speed ratio setpoints, as well as the operating parameters of the drive members (1) driven by the engines (2). Optionally, the processor (6) can receive start, stop, ... commands through the network or other inputs / outputs.
L'unité de pilotage (3) des moteurs électriques (2), reçoit une information représentative de la vitesse des organes de mise en mouvement (1) de l'élément filiforme.The driving unit (3) of the electric motors (2) receives information representative of the speed of the moving members (1) of the filiform element.
Selon une caractéristique à la base de l'invention, au moins un des organes de mise en mouvement est soumis à un mode de démarrage particulier caractérisé par les dispositions essentielles suivantes :
- ce mode de démarrage est enclenché lorsque le moteur est initialement à l'arrêt ;
- le basculement dans le mode de fonctionnement ne déclenche pas de séquence de pilotage du moteur susceptible de provoquer sa mise en rotation immédiate selon un profil d'accélération et peut éventuellement, si la technologie du moteur le permet, provoquer la création d'un couple limité de maintien à l'arrêt ;
- l'unité de pilotage surveille l'information représentative de la vitesse (phase (A)) des organes de mise en mouvement, de sorte que le maintien à l'arrêt (et éventuellement le couple limité de maintien à l'arrêt), est maintenu aussi longtemps que la rotation résultant d'une intervention extérieure n'est pas détectée.
- this start mode is activated when the engine is initially stopped;
- the switchover in the operating mode does not trigger an engine control sequence that can cause it to be immediately rotated according to an acceleration profile and may, if the engine technology allows it, cause the creation of a limited torque holding stationary;
- the control unit monitors the information representative of the speed (phase (A)) of the moving members, so that the holding at a standstill (and possibly the limited holding torque at standstill), is maintained as long as the rotation resulting from an outside intervention is not detected.
Cette intervention extérieure peut être constituée par l'entraînement du fil et/ou de l'organe (1) (phase B), lequel entraînement peut être réalisé manuellement par l'opérateur ou par tout moyen auxiliaire.This external intervention can be constituted by the drive of the wire and / or the member (1) (phase B), which drive can be performed manually by the operator or by any auxiliary means.
Lorsque l'intervention extérieure est détectée, l'unité de pilotage (3) enclenche une séquence de pilotage du moteur (2) (phase (C)), selon un profil de mise en vitesse préprogrammée.When the external intervention is detected, the control unit (3) engages an engine control sequence (2) (phase (C)), according to a preprogrammed speed-up profile.
Selon un perfectionnement de l'invention, une information représentative du sens de rotation de l'organe d'entraînement (1) est disponible, par exemple en association avec l'information représentative de la vitesse dudit organe d'entraînement. Lorsque la rotation provoquée par une intervention extérieure est détectée, l'unité de pilotage (3) vérifie le sens de cette rotation et n'enclenche la séquence de pilotage du moteur (2) de nature à provoquer sa mise en rotation seulement si le sens de rotation est conforme à un sens de rotation prédéterminé.According to an improvement of the invention, an information representative of the direction of rotation of the drive member (1) is available, for example in association with the information representative of the speed of said drive member. When the rotation caused by an external intervention is detected, the control unit (3) verifies the direction of this rotation and engages the motor control sequence (2) to cause its rotation only if the direction rotation is in accordance with a predetermined direction of rotation.
En cas de détection d'un sens de rotation non-conforme, l'unité de pilotage (3) peut, si la technologie du moteur le permet, provoquer la création d'un couple résistant, ce couple pouvant être paramétrable et/ou contrôlé par une limitation de la tension ou du courant par exemple.If a non-compliant direction of rotation is detected, the control unit (3) can, if the engine technology permits, cause the creation of a resistive torque, this torque can be parameterizable and / or controlled by a limitation of the voltage or the current for example.
On renvoie aux
Sur ces courbes, (11) représente une vitesse nominale de consigne et (12) la mise en vitesse sous forme d'une rampe linéaire (
A noter que, lorsque la séquence de pilotage détermine un couple contrôlé par exemple par une limitation de la tension ou du courant, le couple peut être fixe ou dépendre de la vitesse de rotation et être maintenu pendant un temps préprogrammé ou jusqu'à ce que la vitesse atteigne la vitesse du plateau et la vitesse intermédiaire, ou être maintenu jusqu'à la fin du plateau de vitesse intermédiaire, ou encore être maintenu jusqu'à ce que la vitesse atteigne la consigne de vitesse nominale.Note that when the control sequence determines a torque controlled for example by a limitation of the voltage or current, the torque can be fixed or depend on the speed of rotation and be maintained for a pre-programmed time or until the speed reaches the speed of the plate and the intermediate speed, or be maintained until the end of the intermediate speed plate, or be maintained until the speed reaches the nominal speed setpoint.
Dans le moteur à réluctance variable ou à aimants permanents, la séquence d'alimentation est une séquence de commutation des alimentations des bobinages synchronisés par des signaux représentatifs de la position du rotor par rapport au stator (capteurs à effet hall) ou des capteurs de mesure de courant dans les bobines représentatifs de la position du rotor par rapport au stator. Les signaux issus de ces capteurs sont utilisés par le processeur (6) pour détecter et mesurer la vitesse de rotation.In the variable reluctance or permanent magnet motor, the power supply sequence is a switching sequence of the synchronized winding power supplies by signals representative of the position of the rotor with respect to the stator (Hall effect sensors) or measurement sensors current in the coils representative of the position of the rotor relative to the stator. The signals from these sensors are used by the processor (6) to detect and measure the rotational speed.
Les signaux issus de ces capteurs peuvent être aussi exploités pour déterminer le sens de rotation du moteur.The signals from these sensors can also be used to determine the direction of rotation of the motor.
Chaque organe de mise en mouvement (1) dispose d'un mode d'accompagnement au démarrage individuel.Each moving member (1) has an individual start-up support mode.
Chacun des organes d'entraînement dispose de capteurs représentatifs de ces vitesses, et chaque organe attendra une mise en rotation par une intervention extérieure pour accélérer son propre profil de mise en vitesse.Each of the drive members has sensors representative of these speeds, and each member will wait for a rotation by an external intervention to accelerate its own speed profile.
A noter que le dispositif met en oeuvre un programme apte à assurer la détection de la vitesse provoquée par l'intervention extérieure, la gestion des profils de la mise en vitesse et généralement l'exécution de la séquence d'accompagnement telle que décrite. A noter que ces différentes fonctions peuvent être réalisées par un programme exécuté par le processeur (6) de la ou des unité(s) de pilotage (3), ou par une combinaison de l'unité centrale (9) et d'un processeur (6) (
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle :
- l'opérateur peut exercer la mise en mouvement d'un seul geste en toute sécurité, en provoquant lui même la mise en rotation quand il le souhaite,
- le démarrage peut être progressif et sans transition brutale au moment de l'application du fil sur l'organe d'entraînement.
- the operator can exercise the movement of a single gesture safely, causing itself to rotate when he wants,
- starting can be progressive and without abrupt transition at the time of application of the wire on the drive member.

characterized in that:- the control unit of the member is subject to means for measuring the speed of the said member;- when a start order is received, the motor is not started if the measured speed is zero;- the data representative of the speed of at least one of the drive members (1) is monitored;- a control sequence is only initiated that is capable of causing the rotation of the motor (2), according to a preprogrammed speed ramp when a rotation caused (B) by an external action is detected. - Method according to Claim 1, characterized in that, when a rotation of the drive member (1) caused by the external action is detected, the control sequence capable of causing the rotation of the motor (2) is only initiated if the direction of the said rotation conforms to the predefined rotation direction.
- Method according to Claim 2, characterized in that when the rotation caused by the external action which is detected is in the reverse direction to the preprogrammed direction, the creation of a resistive torque is caused, and this torque is parameterable and/or controllable by limiting the voltage or current for example.
- Method according to any one of Claims 1 to 4, characterized in that, upon receiving the start order, the creation of a limit torque is caused for maintaining the stop, the said torque being parameterable and controllable.
- Method according to any one of Claims 1 to 4, characterized in that the external action is the driving of the yarn and/or of the drive member (1), the said driving being carried out manually by an operator or by auxiliary means.
- Method according to any one of Claims 1 to 5, characterized in that the starting process comprises:- a period (A) during which the motor is kept stopped;- a period (B) during which the rotation is caused by the external action;- a period (C) during which the rotation follows the preprogrammed speed ramp; and- a period (D) of operation at nominal speed (O).
- Method according to any one of Claims 1 to 6, characterized in that the preprogrammed speed ramp is a linear ramp (12) or has any shape.
- Method according to any one of Claims 1 to 6, characterized in that:- the preprogrammed speed ramp comprises a plateau (13, 14) at constant intermediate speed, different from a nominal speed setpoint (11);- the said intermediate speed (13) is preprogrammed, or may be the speed of rotation (14) created by the external action and measured by the control unit during a few moments after its detection.
- Method according to Claim 8, characterized in that:- the duration (C2) of the plateau (13, 14) is preprogrammed;- the velocity plateau is maintained until the control unit (3) receives, via an input/output or via a network, an order to terminate the accompaniment mode or to pass into nominal operating mode.
- Method according to any one of claims 1 to 9, characterized in that a torque of a motor or a brake is limited during the execution of the speed ramp.
- Method according to Claim 10, characterized in that the limitation of the torque is fixed and depends on the speed of rotation.
- Method according to Claims 8 and 10, characterized in that the limitation of the torque is maintained for a preprogrammed period- either until the speed reaches the speed of the intermediate speed plateau (13, 14) ;- or until the end of the intermediate speed plateau (13, 14);- or until the speed reaches the nominal speed setpoint (11);- or until the control unit (3) receives, via an input/output or via a network, an order to terminate the accompaniment mode or to pass into nominal operating mode.
- Device for implementing the method according to any one of Claims 1 to 12, comprising linear drive members (1) of the textile yarn, each of said members being subject to an electric motor (2), the motor being associated to at least one control unit (3) suitable for receiving speed setpoints and/or the gear ratio and the start/stop orders, the motor (2) having a variable reluctance or permanent magnets, and of which the power supply sequence is a sequence of switching of the power supplies of windings synchronized by signals representative of the position of the rotor with regard to the stator obtained by sensors (8), the signals from the said sensors being sent to a processor (6) to measure and detect the speed of rotation, characterized in that each drive member (1) has a starting accompaniment mode, and means for awaiting the rotation by an external action to accelerate according to its own speed ramp.
- Device according to Claim 13, characterized in that the signals from the said sensors are used by the processor (6) to determine the direction of rotation of the motor.
- Device according to Claim 13, characterized in that the detection of the speed caused by an external action, the management of the speed ramps, and more generally the execution of the accompanying sequence, are carried out by a program executed by a central processing unit (9), and/or by the processor (6).
