Abstract
Description
La présente invention concerne le domaine du traitement des fibres textiles, notamment au moyen d'une carde dite "pour fibres animales, végétales et chimiques", en particulier la chargeuse destinée à l'alimenter par une nappe de fibres textiles la plus régulière possible.The present invention relates to the field of the treatment of textile fibers, in particular by means of a card known as "for animal, vegetable and chemical fibers", in particular the loader intended to supply it with a sheet of textile fibers as regular as possible.
Les chargeuses connues de ce genre reçoivent généralement leur réserve de fibres par voie pneumatique, par chargement manuel ou par puits de chargement. La réserve repose sur un tablier de hotte, est prise par le tablier à pointes, est détachée de ce dernier par le détacheur et tombe dans la trémie à écartement réglable et à paroi oscillante. Des cylindres délivreurs posent alors cette réserve sur le tablier alimentaire alimentant la carde.Known loaders of this kind generally receive their fiber reserve pneumatically, by manual loading or by loading well. The reserve rests on a hood apron, is taken up by the spiked apron, is detached from the latter by the detacher and falls into the hopper with adjustable spacing and oscillating wall. The delivery cylinders then place this reserve on the food apron supplying the card.
Actuellement, la commande de tous ces organes s'effectue de la manière suivante : une cellule photoélectrique contrôle le niveau des fibres dans la réserve et, dès qu'une hauteur de fibres prédéterminée est atteinte, la cellule est occultée entraînant une commande d'arrêt du ventilateur amenant les paquets de fibres. Lorsque le niveau des fibres dans la hotte baisse jusqu'en-dessous du niveau de la cellule, de sorte que cette dernière est à nouveau dégagée, le ventilateur amenant les fibres est remis en marche. L'épaisseur du matelas de fibres que le tablier à pointes emmène vers la trémie est contrôlée par une autre cellule placée à proximité dudit tablier à pointes.Currently, the control of all these organs is carried out as follows: a photoelectric cell controls the level of fibers in the reserve and, as soon as a predetermined fiber height is reached, the cell is obscured, leading to a stop command of the fan bringing the bundles of fibers. When the level of fibers in the hood drops below the level of the cell, so that the latter is again cleared, the fan bringing the fibers is restarted. The thickness of the fiber mat that the spiked apron takes to the hopper is controlled by another cell placed near said spiked apron.
Le chargement de ce dernier est effectué selon le même principe que celui de la hotte, c'est-à-dire que l'épaisseur du matelas de fibres est contrôlée par la cellule qui est occultée lorsque ladite épaisseur est trop grande, ce qui entraîne une commande d'arrêt de la chargeuse et, lorsque l'épaisseur du matelas est redevenue normale, la cellule est dégagée et commande une remise en marche de la chargeuse.The loading of the latter is carried out according to the same principle as that of the hood, that is to say that the thickness of the fiber mat is controlled by the cell which is obscured when said thickness is too large, which results in a stop command for the loader and, when the thickness of the mattress has returned to normal, the cell is released and commands a restart of the loader.
Une troisième cellule est placée à l'entrée de la trémie et est destinée à commander l'arrêt ou la marche de la chargeuse, selon le même principe que celui décrit plus haut, en fonction de la hauteur de la matière se trouvant dans la trémie.A third cell is placed at the entrance to the hopper and is intended to control the stop or the running of the loader, according to the same principle as that described above, depending on the height of the material in the hopper. .
Les différents points de contrôle de la chargeuse commandent cette dernière en tout ou rien, c'est-à-dire en l'arrêtant ou en la mettant en marche, ce qui entraîne divers inconvénients pour une chargeuse de carde.The different control points of the loader control the latter in all or nothing, that is to say by stopping or starting it, which causes various drawbacks for a card loader.
En effet, le réglage de l'épaisseur de la couche de matière que la chargeuse doit livrer à la carde est difficile à réaliser, de sorte que cette dernière est alimentée d'une manière irrégulière et que le produit sortant en résultant est également irrégulier, d'une qualité discutable et qui engendre des variations importantes du poids spécifique de la masse de fibres.Indeed, the adjustment of the thickness of the layer of material which the loader must deliver to the carding machine is difficult to achieve, so that the latter is fed in an irregular manner and that the resulting outgoing product is also irregular, of questionable quality and which generates significant variations in the specific weight of the mass of fibers.
En outre, l'acheminement de la matière vers la carde est forcément discontinu du fait du fonctionnement discontinu de la chargeuse consistant en de nombreux arrêts et remises en route de cette dernière, ce qui entraîne les mêmes inconvénients que décrits précédemment, c'est-à-dire un produit sortant irrégulier et de mauvaise qualité et qui engendre des variations importantes du poids spécifique de la masse de fibres.In addition, the routing of the material to the carding machine is necessarily discontinuous due to the discontinuous operation of the loader consisting of numerous stops and restarting of the latter, which entails the same drawbacks as described above, that is to say that is to say an outgoing product which is irregular and of poor quality and which generates significant variations in the specific weight of the mass of fibers.
Enfin, les différents organes constitutifs, tels que le tablier de hotte, le tablier à pointes, les cylindres délivreurs et le volant régulateur sont commandés par un moteur à vitesse unique, de sorte qu'il manque de souplesse, ce qui contribue également à l'irrégularité d'alimentation de la carde.Finally, the various constituent parts, such as the hood apron, the spiked apron, the delivery cylinders and the regulating flywheel are controlled by a single speed motor, so that it lacks flexibility, which also contributes to the irregularity in card feeding.
On connaît également, par DE-A-2 139 284, un dispositif d'alimentation de carde qui comporte deux magasins de fibres avec une cellule de surveillance du niveau de la matière et deux tôles déflectrices, dont l'une est conçue de manière à empêcher la formation de ponts de fibres, afin que lesdites fibres ne retombent en arrière, et à permettre le passage des fibres d'un magasin à l'autre, et dont l'autre est destinée à régler le débit des fibres en empêchant leur agglutination et en veillant à éviter un apport excessif de fibres.Also known from DE-A-2 139 284 is a card feeding device which comprises two fiber magazines with a cell for monitoring the level of the material and two deflecting sheets, one of which is designed so as to prevent the formation of fiber bridges, so that said fibers do not fall back, and allow the passage of fibers from one store to another, and the other of which is intended to regulate the flow of fibers by preventing their agglutination and taking care to avoid excessive fiber intake.
Dans ce mode de réalisation, l'ensemble cellule photoélectrique et tôles déflectrices coopère pour l'alimentation régulière d'une carde, aucun réglage des vitesses maximale et minimale des organes d'alimentation de la carde n'étant prévu.In this embodiment, the photoelectric cell and deflector plates assembly cooperates for the regular supply of a card, no adjustment of the maximum and minimum speeds of the card supply members being provided.
La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet une chargeuse pour l'alimentation d'une carde par une nappe de fibres textiles la plus régulière possible, qui est essentiellement constituée par une hotte alimentée en flocons de fibres par un ventilateur, et munie d'une cellule de contrôle du niveau des fibres commandant la marche et l'arrêt du ventilateur, par un tablier de hotte s'étendant sous cette dernière, par un tablier à pointes reprenant les fibres amenées par le tablier de hotte, par une cellule de contrôle de l'épaisseur du matelas de fibres sur le tablier à pointes, par une trémie a écartement réglable et à paroi oscillante chargée par le tablier à pointes et munie, à sa partie inférieure, de cylindres délivreurs coopérant avec un tablier alimentaire réalisant l'alimentation de la carde, caractérisée en ce que le tablier de hotte est entraîné en continu à vitesse variable commandée par la cellule de contrôle de l'épaisseur du matelas de fibres sur le tablier à pointes, la position de cette cellule de contrôle, par rapport au tablier à pointes et au tablier de hotte, étant réglable, en ce que la hotte est munie, en outre, à sa sortie, au-dessus du tablier de hotte, d'une haspel de régulation du flux de fibres, en ce qu'un volant régulateur à vitesse variable coopère avec le tablier à pointes pour la régulation du matelas de fibres pris par ce dernier, et en ce que la trémie est munie de deux cellules de contrôle de niveau, disposées à écartement vertical, et commandant un dispositif de régulation de la vitesse d'entraînement du tablier à pointes, des cylindres délivreurs et du volant régulateur, respectivement à vitesse maximale lorsque le niveau de fibres dans la trémie est en-dessous de la cellule inférieure, à vitesse normale lorsque la cellule inférieure est occultée et lorsque la cellule supérieure est dégagée et à vitesse minimale lorsque les deux cellules sont occultées.Its purpose is, in fact, to provide a loader for feeding a card with a sheet of textile fibers as regular as possible, which is essentially constituted by a hood supplied with flakes of fibers by a fan, and provided with a fiber level control cell controlling the start and stop of the fan, by a hood apron extending under the latter, by a spiked apron taking up the fibers brought by the hood apron, by a control cell the thickness of the fiber mat on the spiked apron, by a hopper with adjustable spacing and an oscillating wall loaded by the spiked apron and provided, at its lower part, with delivery cylinders cooperating with a food apron supplying the card, characterized in that the hood apron is continuously driven at variable speed controlled by the cell for controlling the thickness of the fiber mat on the apron to points, the position of this control cell, by relative to the spiked apron and to the hood apron, being adjustable, in that the hood is provided, in addition, at its outlet, above the hood apron, with a haspel for regulating the flow of fibers, in this that a variable speed flywheel cooperates with the spiked apron for the regulation of the fiber mat taken by the latter, and in that the hopper is provided with two level control cells, arranged at vertical spacing, and controlling a device for regulating the drive speed of the spiked apron, the delivery cylinders and the regulating flywheel, respectively at maximum speed when the fiber level in the hopper is below the lower cell, at normal speed when the lower cell is obscured and when the upper cell is cleared and at minimum speed when the two cells are obscured.
L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en coupe de la chargeuse conforme à l'invention.The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, the single figure of which is a view in section of the loader according to the invention.
La figure du dessin annexé représente une chargeuse pour l'alimentation d'une carde 14 par une nappe de fibres textiles la plus régulière possible, qui est essentiellement constituée par une hotte 2 alimentée en flocons 1 de fibres par un ventilateur, non représenté, et munie d'une cellule 3 de contrôle du niveau des fibres commandant la marche et l'arrêt du ventilateur. Un tablier de hotte 5 est disposé sous cette dernière et amène la matière fibreuse 4 à un tablier à pointes 6. L'épaisseur du matelas de fibres sur le tablier à pointes 6 est contrôlée par une cellule 7, puis ledit matelas est amené à une trémie 11 à écartement réglable et à paroi oscillante chargée par le tablier à pointes 6 et munie, à sa partie inférieure, de cylindres délivreurs 12 coopérant avec un tablier alimentaire 13 réalisant l'alimentation de la carde 14.The figure of the appended drawing represents a loader for feeding a
Conformément à l'invention, la chargeuse est pourvue d'un tablier de hotte 5, qui est entraîné en continu à vitesse variable commandée par la cellule 7 de contrôle de l'épaisseur du matelas de fibres sur le tablier à pointes 6.In accordance with the invention, the loader is provided with a
En outre, la hotte 2 est munie à sa sortie, au-dessus du tablier de hotte 5, d'une haspel 8 de régulation du flux de fibres sortant de ladite hotte 2 et un volant régulateur 9 à vitesse variable coopère avec le tablier à pointes 6 pour la régulation du matelas de fibres pris par ce dernier.In addition, the
Les flocons 1 de fibres sont amenés dans la hotte 2 par le ventilateur, non représenté, et leur niveau dans ladite hotte 2 est contrôlé par la cellule 3 qui, tant qu'elle est dégagée, maintient le fonctionnement du ventilateur et, dès qu'elle est occultée, commande l'arrêt de ce dernier.The fiber flakes 1 are brought into the
La matière fibreuse 4, qui repose sur le tablier de hotte 5, est amenée par ce dernier au tablier à pointes 6 et l'épaisseur du matelas de fibres 4 sur ledit tablier à pointes 6 est contrôlée par la cellule 7. Cette dernière réalise la commande de la vitesse de la chargeuse en permettant un fonctionnement à vitesse normale lorsqu'elle est dégagée et un fonctionnemant à vitesse minimale prédéterminée lorsqu'elle est occultée.The fibrous material 4, which rests on the
Un tel fonctionnement à vitesse minimale a pour effet de ralentir le chargement du tablier à pointes 6.Such operation at minimum speed has the effect of slowing down the loading of the
Conformément à une caractéristique de l'invention, la position de la cellule 7, par rapport au tablier à pointes 6 et au tablier de hotte 5, est réglable. Ainsi, l'épaisseur du matelas de fibres sur le tablier à pointes 6 peut être réglée.According to a characteristic of the invention, the position of the
Le matelas de fibres entraîné par le tablier à pointes 6 est régulé, en outre, par l'haspel 8 et par le volant régulateur 9. A son extrémité supérieure, le tablier à pointes 6 déverse les paquets 10 de fibres dans la trémie 11 à écartement réglable et à paroi oscillante, par coopération avec le cylindre détacheur 17, ladite trémie 11 alimentant la carde 14 par l'intermédiaire des cylindres délivreurs 12 coopérant avec le tablier alimentaire 13.The fiber mat driven by the
Selon une caractéristique de l'invention, la trémie 11 est munie de deux cellules 15 et 16 de contrôle de niveau, disposées à écartement vertical, et commandant un dispositif de régulation (non représenté) de la vitesse d'entraînement du tablier à pointes 6, des cylindres délivreurs 12 et du volant régulateur 9, respectivement à vitesse maximale lorsque le niveau de fibres dans la trémie 11 est en-dessous de la cellule inférieure 15, à vitesse normale lorsque la cellule 15 est occultée et lorsque la cellule 16 est dégagée et à vitesse minimale lorsque les deux cellules sont occultées. Ainsi, il est possible d'opérer un contrôle continu de niveau dans la trémie 11 et de maintenir ce niveau à peu près constant en réalisant, soit un rattrapage de hauteur de matière, soit un maintien de niveau, soit une perte de hauteur de matière.According to a characteristic of the invention, the
La chargeuse conforme à l'invention permet de réaliser, facilement et aisément, un réglage de l'épaisseur de la couche de fibres qu'elle doit livrer à la carde, de sorte que cette dernière est alimentée d'une manière régulière et que le produit sortant est également régulier et d'une bonne qualité.The loader according to the invention makes it possible to easily and easily adjust the thickness of the layer of fibers which it must deliver to the carding machine, so that the latter is fed in a regular manner and that the outgoing product is also regular and of good quality.
En outre, l'acheminement des fibres vers la carde s'effectue de manière continue, du fait que la chargeuse tourne constamment, c'est-à-dire sans arrêt de l'un de ses éléments constitutifs, ce qui contribue également à la régularité et à la bonne qualité du produit sortant.In addition, the routing of the fibers to the carding machine is carried out continuously, owing to the fact that the loader rotates constantly, that is to say without stopping one of its constituent elements, which also contributes to the consistency and good quality of the outgoing product.
Enfin, les organes mobiles tels que le tablier de hotte 5, le tablier à pointes 6, les cylindres délivreurs 12 et le volant régulateur 9 étant commandés à vitesse variable, ils présentent une certaine souplesse de fonctionnement contribuant à la régularité d'alimentation de la carde 14.Finally, the movable members such as the
Grâce à l'invention, il est possible de réaliser une chargeuse fonctionnant en continu à vitesse variable pour réguler au mieux la matière fibreuse alimentant la carde.Thanks to the invention, it is possible to produce a loader operating continuously at variable speed to best regulate the fibrous material supplying the card.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
