Abstract

The mounting of a cylindrical cleaning brush at the circular comb of a comber is in an assembly which has a fixed comb (1), a cylinder (2), a cylindrical cleaning brush (3), a doffer (4) and a doffer comb (5) to work an incoming fiber web (6). A system (7) gives a rapid assembly and dismantling action on the brush cylinder (3) on a drive shaft (3'), together with an automatic compensation system (8) for the wear on the brush (3). The drive shaft (3') for the brush cylinder (3) is longer than the brush (3). One end of the shaft has a fitting for the assembly/dismantling system (7), and the shaft has an inner limit stop and centering unit for the fitted brush cylinder (3). The shaft fitting has a structured profile to be gripped by the assembly-dismantling system and give it an axial block at the shaft such as a tapping to take a locking bolt. The inner centering unit is a cone, fitted to the drive shaft (3'), working with a positioning cuff at the assembly/dismantling system (7) for the brush cylinder (3). The assembly/dismantling system (7) has a handwheel for movement with the positioning cuff. The far end of the handwheel is structured to fit the splined shaft and a female cone to work with the centering cone. An elastic stop acts on the positioning cuff, against a return spring without rotation. It also has snap connections to engage fittings at the end of the center tube of the brush cylinder (3). The snap connections are friction grips with at least one elastic, metal or synthetic rush in a circular groove which grips by friction within the brush cylinder tube with the elastic stop. The system (8) to give an automatic compensation for brush (3) wear has at least one actuator (19) working with the swing support (16) for the brush drive shaft (3'), to swing it on its axis in at least one perpendicular direction, through a control unit (20). The actuator (19) has a conventional or step electromotor (21), which is reversible and is fitted with a reduction gearing (22). The motor rotation is converted (23) mechanically into a setting movement for the brush cylinder (3). The motor drive output is engaged and disengaged by a clutch between the motor (21) and the mechanical movement converter (23) through a manual control (24). The mechanical movement converter (23) has an initial transmissions section such as a pinion, drive wheel or pulley (25) on the motor drive shaft. It acts with a second transmission pinion, drive wheel or pulley unit (26) and through a thrust bearing (28), to operate a screw bolt (27) through a screw block (29) at the support arm (16), to act as a spindle to move it in one of two directions. The spindle screw (27) can be operated by the electromotor (21) through a toothed segment which pivots on the frame (18) acting on a push rod, eccentric or cam to move the support arm (16). The set position of the swing support arm (16) for the brush cylinder drive shaft (3') is held in place by a variety of systems such as springs, elastic washers, pneumatic or hydraulic units, and the like. The control unit (20) has a programmable follow-up system, to set the phased shifts of the brush support arm (16), and operate the motor to ensure that the diameter of the brush cylinder is effectively placed as the bristles wear. The brush assembly/dismantling system (7) has a bearing for the movement of the positioning cuff, with bearing rollers at its guide. The guide has a curvature matching the swing movements of the brush support arm (16), and a guide plate to hold the roller bearing at the frame (18) in front of a passage opening at an upper covering surface. The automatic compensation system has a moving stop against the roller bearing of the assembly/dismantling system (7). It is mounted to a swing lever at one end of the frame (18) with an operating unit at the other end of the lever. The operating unit has a swing lever fitted to the frame (18) at one end with a rod of variable length at the other end. It is worked by a pedal or lever, with a limit stop to define the movement range. It is also fitted with a shock absorber. The rod with a variable length is telescopic, where an inner section slides within an outer sheath. It has a spring and a retaining ring. The operating unit can also be a piston acting on the lever, set by a control button.

Description

La présente invention concerne le domaine de l'industrie textile, notamment des peigneuses rectilignes, et a plus particulièrement pour objet un dispositif de montage d'une brosse cylindrique de nettoyage du peigne cylindrique d'une peigneuse rectiligne à compensation automatique de l'usure de ladite brosse.The present invention relates to the field of the textile industry, in particular rectilinear combing machines, and more particularly has for object a device for mounting a cylindrical brush for cleaning the cylindrical comb a straight combing machine with automatic compensation for the wear of said brush.

Actuellement, sur une peigneuse rectiligne, lors de la phase de peignage des têtes de fibres, la pince est fermée et abaissée vers le peigne cylindrique afin de présenter les têtes de fibres dépassant de la pince à des segments de garniture dentée ou à des barrettes garnies d'aiguilles du peigne cylindrique. Ce dernier est chargé de peigner ces têtes de fibres afin de les débarrasser des impuretés, par exemple végétales, telles que pailles et chardons, ainsi que d'une quantité prédéterminée de fibres très courtes qui peuvent être néfastes au processus ultérieur de la filature.Currently, on a straight combing machine, during the combing the fiber heads, the clamp is closed and lowered towards the comb cylindrical in order to present the fiber heads protruding from the gripper at segments of toothed trim or barrettes with comb needles cylindrical. The latter is responsible for combing these fiber heads in order to rid of impurities, for example vegetable impurities, such as straws and thistles, as well as a predetermined amount of very short fibers that can be harmful to the subsequent spinning process.

La blousse, qui est l'ensemble constitué par les fibres très courtes et par les impuretés entraínées par le peigne cylindrique, est retirée du peigne cylindrique par la brosse cylindrique, qui tourne plus vite que le peigne cylindrique, mais dans le sens opposé. Cette blousse collectée par la brosse est ensuite prélevée par un cylindre garni de pointes appelé le doffer, qui est ensuite déchargé par un peigne battant. La blousse tombe alors dans un bac à partir duquel elle est souvent aspirée pour être convoyée à l'extérieur de la machine.The blouse, which is the set made up of very short fibers and by impurities entrained by the cylindrical comb, is removed from the comb cylindrical by the cylindrical brush, which rotates faster than the comb cylindrical, but in the opposite direction. This blouse collected by the brush is then removed by a cylinder with spikes called the doffer, which is then discharged by a beating comb. The blister then falls into a bin from which it is often vacuumed up to be conveyed outside the machine.

Le rôle principal de la brosse cylindrique est d'assurer un nettoyage efficace du peigne cylindrique et d'entraíner la blousse. Il est, en effet, primordial que le peigne cylindrique soit nettoyé efficacement pour la prochaine phase de peignage des têtes de fibres. A cet effet, les poils de la brosse cylindrique pénètrent entre les dents ou les aiguilles du peigne cylindrique . Il résulte de cette action mécanique que les poils de la brosse cylindrique 3 sont repoussés en arrière et s'usent progressivement.The main role of the cylindrical brush is to ensure cleaning effective of the cylindrical comb and train the bush. It is, in fact, essential that the cylindrical comb is effectively cleaned for the next phase of combing the fiber heads. For this purpose, the bristles of the cylindrical brush penetrate between the teeth or the needles of the cylindrical comb. It follows from this mechanical action that the bristles of the cylindrical brush 3 are pushed back and wear out gradually.

Pour garantir une bonne qualité textile du produit sortant, il est donc nécessaire de compenser l'usure des poils de la brosse cylindrique en la rapprochant périodiquement du peigne cylindrique et de procéder périodiquement à un retournement de ladite brosse cylindrique, afin d'en redresser les poils.To guarantee good textile quality of the outgoing product, it is therefore necessary to compensate for the wear of the bristles of the cylindrical brush by periodically approaching the cylindrical comb and proceeding periodically inverting said cylindrical brush in order to straighten the bristles.

Ces manipulations nécessaires au démontage et au remontage de la brosse cylindrique sont, cependant, perfectibles notamment en ce qui concerne l'ergonomie et l'accessibilité. En effet, ces opérations exigent un arrêt prolongé de marche de la machine entraínant une perte de productivité et une augmentation de la charge ouvrière correspondante. En outre, les manipulations sont également peu agréables car l'accès à la brosse est étroit.These manipulations necessary for disassembly and reassembly of the cylindrical brush are, however, perfectible in particular with regard to ergonomics and accessibility. Indeed, these operations require an extended shutdown of machine operation resulting in lost productivity and increased the corresponding workload. In addition, the manipulations are also little pleasant because the access to the brush is narrow.

Par GB-A-250 031, on connaít un dispositif de nettoyage du peigne circulaire d'une peigneuse circulaire au moyen d'une brosse rotative montée en porte-à-faux sur un support orientable, et dont on peut corriger la position par rapport au peigne circulaire, de façon à compenser l'usure des poils de la brosse. Le support de la brosse est pivotant de sa position de travail à celle de repos, de manière à permettre le démontage et l'échange de la brosse sans avoir à démonter le support. La brosse, qui peut être de toutes formes usuelles, est montée de façon amovible sur l'arbre du support par un moyen de connexion rapide. Cependant, le montage de cette brosse par rapport au peigne circulaire est encombrant et incompatible avec une utilisation sur des machines de peignages modernes. En outre, les différentes manoeuvres de la brosse sont effectuées manuellement, sans prévision de moyens pouvant permettre de compenser automatiquement l'usure des poils de la brosse.By GB-A-250 031, there is known a comb cleaning device circular of a circular combing machine by means of a rotary brush mounted in overhang on an adjustable support, and whose position can be corrected by relative to the circular comb, so as to compensate for the wear of the bristles of the brush. The brush support is pivotable from its working position to that of rest, so as to allow disassembly and exchange of the brush without having to disassemble the support. The brush, which can be of any usual shape, is mounted so removable on the support shaft by a quick connection means. However, the mounting this brush relative to the circular comb is bulky and incompatible with use on modern combing machines. In in addition, the various operations of the brush are carried out manually, without provision of means that can automatically compensate for wear brush bristles.

Par ailleurs, EP-A-0 493 336 décrit une tête de peignage pourvue de brosses de nettoyage des peignes d'un groupe de peignage, dans laquelle lesdites brosses de nettoyage sont montées de manière démontable axialement, c'est-à-dire par le côté de la machine. Un tel montage des brosses permet de faciliter leur remplacement à l'arrêt de la machine. Toutefois, ces brosses ne présentent aucun moyen de compensation de la position des brosses par rapport aux peignes des groupes de peignage pendant le fonctionnement de la machine.Furthermore, EP-A-0 493 336 describes a combing head provided with comb cleaning brushes of a combing group, wherein said combs cleaning brushes are axially demountable, i.e. from the side of the machine. Such mounting of the brushes facilitates their replacement when the machine is stopped. However, these brushes have no means for compensating the position of the brushes relative to the combs of the combing groups during machine operation.

La présente invention a pour but de pallier les inconvénients des dispositifs de montage de la brosse cylindrique de nettoyage du peigne cylindrique connus en proposant un tel dispositif de montage permettant un démontage et un remontage rapides de la brosse cylindrique de nettoyage du peigne cylindrique d'une peigneuse rectiligne, ainsi qu'une prise en compte de l'usure de ladite brosse avec compensation automatique de cette dernière.The object of the present invention is to overcome the drawbacks of the mounting devices for the cylindrical comb cleaning brush known by proposing such a mounting device allowing disassembly and quick reassembly of the cylindrical comb cleaning brush a straight combing machine, as well as taking into account the wear of said brush with automatic compensation of the latter.

A cet effet, le dispositif de montage d'une brosse cylindrique de nettoyage du peigne cylindrique d'une peigneuse rectiligne, conforme à l'invention est caractérisé en ce qu'il est pourvu, d'une part, d'un moyen de démontage, de remontage et de fixation rapides de la brosse cylindrique sur son arbre d'entraínement et, d'autre part, d'un moyen de compensation automatique de l'usure de la brosse cylindrique.To this end, the device for mounting a cylindrical brush of cleaning the cylindrical comb of a rectilinear comber, according to the invention is characterized in that it is provided, on the one hand, with a disassembly means, quick reassembly and fixing of the cylindrical brush on its shaft drive and, on the other hand, an automatic compensation means of wear of the cylindrical brush.

    • La figure 1 des dessins annexés représente, à titre d'exemple une peigneuse rectiligne essentiellement constituée par un peigne fixe 1, par un peigne cylindrique 2, par une brosse cylindrique de nettoyage 3, par un doffer 4 et par un peigne détacheur 5, traitant une nappe de fibres entrantes 6.Figure 1 of the accompanying drawings shows, by way of example a rectilinear combing machine essentially constituted by a fixed comb 1, by a comb cylindrical 2, by a cylindrical cleaning brush 3, by a doffer 4 and by a detacher comb 5, treating a sheet of incoming fibers 6.

    Conformément à l'invention, le dispositif de montage de la brosse cylindrique 3 de nettoyage du peigne cylindrique 2 est pourvu, d'une part, d'un moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 sur son arbre d'entraínement 3' et, d'autre part, d'un moyen 8 de compensation automatique de l'usure de la brosse cylindrique 3.According to the invention, the brush mounting device cylindrical 3 for cleaning the cylindrical comb 2 is provided, on the one hand, with a means 7 for rapid disassembly, reassembly and fixing of the brush cylindrical 3 on its drive shaft 3 'and, on the other hand, a means 8 of automatic compensation for the wear of the cylindrical brush 3.

    De manière connue, la brosse cylindrique de nettoyage 3 est constituée par un corps tubulaire, sur lequel sont fixés les poils, et est montée en butée sur son arbre d'entraínement 3' de manière centrée et avec possibilité d'entraínement en rotation dudit arbre d'entraínement 3' par l'intermédiaire d'ergots 3'' coopérant avec des encoches 3''' du corps tubulaire (figures 3 à 8). En vue de permettre le retournement de la brosse et son entraínement sur l'arbre 3', le corps tubulaire de cette dernière est avantageusement pourvu à ses deux extrémités d'encoches 3'''. Par ailleurs, l'arbre d'entraínement 3' est monté à une extrémité sur des roulements 9 dans un palier 10 et est entraíné en rotation par des moyens connus, non représentés aux dessins annexés. Près de ce palier 10, l'arbre 3' est muni d'une butée axiale concentrique 11 pourvue des ergots 3'' d'entraínement de la brosse 3.In known manner, the cylindrical cleaning brush 3 is constituted by a tubular body, on which the bristles are fixed, and is mounted in stop on its drive shaft 3 'centered and with possibility for driving in rotation of said drive shaft 3 'by means of pins 3 '' cooperating with notches 3 '' 'of the tubular body (Figures 3 to 8). With a view to allow the brush to turn over and drive it onto the 3 'shaft, the body tubular of the latter is advantageously provided at its two ends 3 '' notches. Furthermore, the drive shaft 3 'is mounted at one end on bearings 9 in a bearing 10 and is rotated by means known, not shown in the accompanying drawings. Near this bearing 10, the shaft 3 'is provided with a concentric axial stop 11 provided with pins 3 '' for driving the brush 3.

    Selon une caractéristique de l'invention, l'arbre 3' d'entraínement de la brosse 3 présente une longueur supérieure à celle de ladite brosse 3 et est muni, d'une part, à son extrémité libre, d'un moyen 12 destiné à coopérer avec le moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 et, d'autre part, sur sa partie s'étendant à l'intérieur de la brosse cylindrique 3, d'un moyen 13 de butée et de centrage dudit moyen 7 de démontage, de remontage et de fixation rapides de ladite brosse cylindrique 3 (figures 3, 5 et 7).According to a characteristic of the invention, the shaft 3 'for driving the brush 3 has a length greater than that of said brush 3 and is provided, on the one hand, at its free end, a means 12 intended to cooperate with the means 7 for rapid disassembly, reassembly and fixing of the cylindrical brush 3 and, on the other hand, on its part extending inside the cylindrical brush 3, of a means 13 for stopping and centering said means 7 for disassembly, reassembly and fast fixing of said cylindrical brush 3 (Figures 3, 5 and 7).

    Le moyen 12, destiné à coopérer avec le moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 réalise le blocage en rotation et le centrage du moyen 7 sur l'arbre d'entraínement 3' et se présente avantageusement sous forme d'une partie d'extrémité cannelée, clavetée ou autre de l'arbre d'entraínement 3', ladite extrémité étant pourvue, en outre, d'un moyen de blocage axial du moyen 7 sur l'arbre d'entraínement 3', tel qu'un taraudage destiné à coopérer avec une vis 14 de serrage du moyen 7 sur l'arbre d'entraínement 3'.The means 12, intended to cooperate with the means 7 for dismantling, rapid reassembly and fixing of the cylindrical brush 3 achieves the locking in rotation and centering of the means 7 on the drive shaft 3 'and is presented advantageously in the form of a grooved, keyed or other end portion of the drive shaft 3 ', said end being further provided with a means axial locking of the means 7 on the drive shaft 3 ', such as a thread intended to cooperate with a screw 14 for clamping the means 7 on the shaft 3 'drive.

    Le moyen 13 de butée et de centrage du moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 est constitué par un centreur conique solidaire de l'arbre d'entraínement 3' coopérant, en position de service de la brosse cylindrique 3, avec un manchon de positionnement 7' du moyen 7. Ainsi, le moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 peut être parfaitement centré et serré sur l'arbre d'entraínement 3' de la brosse 3.The means 13 for stopping and centering the means 7 for disassembly, rapid reassembly and fixing of the cylindrical brush 3 consists of a conical centering device secured to the cooperating drive shaft 3 ', in the position of cylindrical brush service 3, with a positioning sleeve 7 'of the means 7. Thus, the means 7 for rapid disassembly, reassembly and fixing of the cylindrical brush 3 can be perfectly centered and tightened on the shaft drive 3 'of the brush 3.

    Ce moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 est constitué, d'une part, par un élément de manoeuvre sous forme d'un volant muni d'un manchon de positionnement 7' s'étendant concentriquement sur un côté dudit volant et dont l'extrémité solidaire du volant est pourvue d'un dispositif de blocage en rotation et de centrage tel que des cannelures coopérant avec celles de la partie d'extrémité cannelée de l'arbre d'entraínement 3', l'extrémité distale présentant un cône femelle destiné à coopérer avec le centreur conique formant le moyen 13 de butée et de centrage du moyen 7 et, d'autre part, par une butée élastique 15 montée à coulissement contre l'action d'un ressort de rappel 15' sur le manchon de positionnement 7', sans possibilité de rotation par rapport à ce dernier, et pourvue de moyens 15'' de connexion rapide destinés à coopérer avec le corps tubulaire de la brosse 3. Ainsi, les moyens de connexion rapide 15'' peuvent être amenés dans le corps tubulaire de la brosse 3, afin de réaliser la solidarisation de la brosse 3 avec le moyen 7, pour permettre la mise en place et le retrait de ladite brosse 3.This means 7 for rapid disassembly, reassembly and fixing of the cylindrical brush 3 is constituted, on the one hand, by an operating element under shape of a steering wheel fitted with a positioning sleeve 7 'extending concentrically on one side of said flywheel and whose end secured to the flywheel is provided with a rotation locking and centering device such as splines cooperating with those of the splined end portion of the shaft 3 'drive, the distal end having a female cone intended to cooperate with the conical centering device forming the stop 13 and centering means of the means 7 and, on the other hand, by an elastic stop 15 mounted to slide against the action a return spring 15 'on the positioning sleeve 7', without the possibility of rotation relative to the latter, and provided with 15 '' quick connection means intended to cooperate with the tubular body of the brush 3. Thus, the means of quick connection 15 '' can be brought into the tubular body of the brush 3, in order to secure the brush 3 with the means 7, to allow the placing and removing said brush 3.

    Le montage de la brosse est effectué par enfilage de ladite brosse 3 et du moyen 7 sur l'arbre d'entraínement 3'. Dans cette position, la rotation du moyen 7 autour de l'arbre d'entraínement 3' est possible car le dispositif de blocage en rotation et de centrage constitué par les cannelures du moyen 7 ne coopère pas avec l'extrémité cannelée de l'arbre d'entraínement 3'. La rotation du volant autour de l'arbre d'entraínement 3' permet, de ce fait, respectivement aux moyens de connexion rapide 15'' et aux ergots 3'' d'entraínement de coopérer avec le corps tubulaire de la brosse 3 et avec les encoches 3''' correspondantes du corps de la brosse 3.The brush is assembled by threading said brush 3 and means 7 on the drive shaft 3 '. In this position, the rotation of the means 7 around the drive shaft 3 'is possible because the locking device in rotation and centering formed by the grooves of the means 7 does not cooperate with the grooved end of the drive shaft 3 '. The rotation of the steering wheel around of the drive shaft 3 'therefore allows, respectively, the means of 15 '' quick connection and 3 '' drive pins to cooperate with the body tubular of the brush 3 and with the corresponding notches 3 '' 'of the body of the brush 3.

    Un déplacement axial consécutif du volant muni du manchon de positionnement 7' permet de provoquer l'enclenchement du dispositif de blocage en rotation et de centrage formé par les cannelures du moyen 7 avec celles de la partie d'extrémité cannelée de l'arbre d'entraínement 3'. Cet enclenchement est maintenu par le dispositif' de blocage axial formé par la vis de serrage 14. Il résulte de ce montage qu'en fonctionnement la butée élastique 15 est en butée axiale sur l'arbre d'entraínement 3' et permet de mettre en pression le corps de la brosse cylindrique 3 contre la butée axiale concentrique 11.A consecutive axial movement of the steering wheel fitted with the sleeve positioning 7 'allows the locking device to be engaged in rotation and centering formed by the grooves of the means 7 with those of the grooved end part of the drive shaft 3 '. This engagement is held by the axial locking device formed by the clamping screw 14. It results of this assembly that in operation the elastic stop 15 is in axial stop on the drive shaft 3 'and allows to pressurize the body of the brush cylindrical 3 against the concentric axial stop 11.

    Dans cette configuration, la brosse cylindrique 3 est parfaitement positionnée par rapport à son arbre d'entraínement 3' et par rapport au peigne cylindrique 2 et est entraínée en rotation uniquement par la butée axiale concentrique 11, du côté de son extrémité latérale proche du palier 10.In this configuration, the cylindrical brush 3 is perfectly positioned relative to its drive shaft 3 'and relative to the comb cylindrical 2 and is rotated only by the axial stop concentric 11, on the side of its lateral end close to the bearing 10.

    Le démontage de la brosse 3 s'effectue par dévissage de la vis de serrage 14 formant le dispositif de blocage axial du moyen 7, puis par retrait axial dudit moyen 7, préalablement rendu solidaire du corps de la brosse 3 grâce aux moyens de connexion rapide 15'' coopérant avec la partie perpendiculaire des encoches 3''' du corps de la brosse 3. Lorsque la brosse 3 est suffisamment dégagée du bâti 18 de la machine, c'est-à-dire lorsque la brosse est facilement accessible manuellement, le moyen 7 est séparé du corps de la brosse 3 et l'extraction axiale dudit corps de la brosse 3 est poursuivie.The brush 3 is disassembled by unscrewing the screw tightening 14 forming the axial locking device of the means 7, then by axial withdrawal said means 7, previously made integral with the body of the brush 3 thanks to quick connection means 15 '' cooperating with the perpendicular part of the notches 3 '' 'on brush body 3. When brush 3 is sufficient clear of the frame 18 of the machine, that is to say when the brush is easily manually accessible, the means 7 is separated from the body of the brush 3 and the axial extraction of said body of the brush 3 is continued.

    Conformément à une variante de réalisation de l'invention, et comme le montrent les figures 7 et 8 des dessins annexés, les moyens de connexion rapide 15'' du moyen 7 coopèrent par friction avec le corps tubulaire de la brosse cylindrique 3. Ainsi, la butée élastique 15 peut, par exemple, être munie d'au moins une rainure circulaire à l'intérieur de laquelle est monté un jonc élastique, métallique ou en matière synthétique, de dimension supérieure à celle de la rainure, immobilisé en rotation par rapport à la butée élastique 15 et destiné à solidariser par friction la partie intérieure du corps tubulaire de la brosse cylindrique 3 avec la butée élastique 15 du moyen 7. Du fait de la solidarisation du corps de la brosse 3 avec le moyen 7 de démontage, remontage et fixation rapides, il est possible, d'une part, de faire coopérer les encoches 3''' du corps de la brosse 3 avec les ergots d'entraínement 3'', lors du montage de ladite brosse 3, en actionnant le volant du moyen 7 et, d'autre part, d'extraire simultanément le corps de la brosse 3, lors du démontage de ladite brosse 3, en retirant axialement le volant du moyen 7.In accordance with an alternative embodiment of the invention, and as shown in Figures 7 and 8 of the accompanying drawings, the quick connection means 15 '' of the means 7 cooperate by friction with the tubular body of the brush cylindrical 3. Thus, the elastic stop 15 may, for example, be provided with minus a circular groove inside which an elastic ring is mounted, metallic or synthetic material, larger than that of the groove, immobilized in rotation relative to the elastic stop 15 and intended to securing by friction the inner part of the tubular body of the brush cylindrical 3 with the elastic stop 15 of the means 7. Due to the connection of the brush body 3 with fast disassembly, reassembly and fixing means 7, on the one hand, it is possible to make the notches 3 '' 'of the brush body 3 cooperate with the drive pins 3 '', when mounting said brush 3, actuating the handwheel of the means 7 and, on the other hand, simultaneously extracting the body of the brush 3, during the disassembly of said brush 3, by axially removing the steering wheel 7.

    Le moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 permet ainsi un montage et un démontage rapides et aisés de la brosse cylindrique par des manipulations parfaitement ergonomiques, l'accès à la brosse 3 étant amélioré. En outre, du fait de la symétrie par retournement des extrémités du corps de la brosse cylindrique 3, à savoir de la disposition des encoches 3''', ladite brosse 3 est parfaitement positionnée longitudinalement sur son arbre d'entraínement 3' par rapport au peigne cylindrique 2.The means 7 for rapid disassembly, reassembly and fixing of the cylindrical brush 3 thus allows quick and easy assembly and disassembly of the cylindrical brush by perfectly ergonomic manipulations, access to the brush 3 being improved. In addition, due to the inversion symmetry of the ends of the body of the cylindrical brush 3, namely of the arrangement of the notches 3 '' ', said brush 3 is perfectly positioned longitudinally on its drive shaft 3 'relative to the cylindrical comb 2.

    De manière connue, l'arbre d'entraínement 3' avec son palier 10 est monté sur un support 16 pouvant pivoter autour d'un axe d'articulation 17 fixé au bâti 18 de la machine. La position de cet axe d'articulation 17 est avantageusement telle que l'arc décrit par l'arbre d'entraínement 3', lors de son mouvement de pivotement, peut être assimilé à un segment rectiligne.In known manner, the drive shaft 3 'with its bearing 10 is mounted on a support 16 which can pivot around a hinge pin 17 fixed to the frame 18 of the machine. The position of this hinge pin 17 is advantageously such as the arc described by the drive shaft 3 ', during its movement of pivot, can be likened to a straight segment.

    Le moyen 8 de compensation automatique de l'usure de la brosse cylindrique 3 est essentiellement constitué par au moins un actionneur 19 coopérant avec le support pivotant 16 de l'arbre d'entraínement 3' de la brosse cylindrique 3 pour déplacer cette dernière dans au moins une direction perpendiculaire à son axe et par un dispositif 20 de commande et de contrôle automatique de la position de la brosse cylindrique 3 (figures 1 et 2). Ainsi, la brosse cylindrique 3 peut être rapprochée plus ou moins du peigne cylindrique 2 et du doffer 4, en fonction de sa direction et de son sens de déplacement. Si la brosse cylindrique 3 se rapproche du peigne cylindrique 2, les poils ou touffes, dont elle est garnie, pénètrent entre les dents ou les aiguilles du peigne cylindrique 2, même si les poils ou touffes sont courbés ou repliés, et les débarrassent complètement des fibres courtes et des impuretés végétales qui les encombrent.The means 8 of automatic compensation for the wear of the brush cylindrical 3 is essentially constituted by at least one actuator 19 cooperating with the pivoting support 16 of the drive shaft 3 'of the brush cylindrical 3 to move the latter in at least one direction perpendicular to its axis and by a command and control device 20 automatic position of the cylindrical brush 3 (Figures 1 and 2). So the cylindrical brush 3 can be brought closer or closer to the cylindrical comb 2 and doffer 4, depending on its direction and direction of movement. If the brush cylindrical 3 approaches the cylindrical comb 2, the bristles or tufts, of which it is trimmed, penetrate between the teeth or the needles of the cylindrical comb 2, even if the hairs or tufts are bent or folded, and rid them completely short fibers and vegetable impurities that clog them.

    Par contre, les aiguilles du doffer 4 ne pénètrent pas dans les poils ou touffes de la brosse cylindrique 3, mais restent tangentes à ces dernières et peuvent même présenter un petit jeu avec ceux-ci. La position de la brosse cylindrique 3 doit donc être telle qu'elle assure, d'une part, une interpénétration optimale entre la brosse cylindrique 3 et le peigne cylindrique de 2 et, d'autre part, la tangence entre la brosse cylindrique 3 et le doffer 4.On the other hand, the needles of doffer 4 do not penetrate the hairs or tufts of the cylindrical brush 3, but remain tangent thereto and may even present a little game with these. The position of the cylindrical brush 3 must therefore be such that it ensures, on the one hand, an optimal interpenetration between the cylindrical brush 3 and the cylindrical comb of 2 and, on the other hand, the tangency between the cylindrical brush 3 and the doffer 4.

    Conformément à une caractéristique de l'invention et comme le montrent plus particulièrement les figures 1 et 2 des dessins annexés, l'actionneur 19, coopérant avec le support pivotant 16 de l'arbre d'entraínement 3' de la brosse cylindrique 3, est constitué par un moteur électrique 21, conventionnel ou pas-à-pas, réversible et/ou muni d'un réducteur 22 commandé par le dispositif 20 de commande et de contrôle automatique de la position de la brosse cylindrique 3, et par un dispositif mécanique 23 de transformation du mouvement de rotation dudit moteur électrique 21 en mouvement de déplacement de la brosse cylindrique 3.In accordance with a feature of the invention and as the more particularly show Figures 1 and 2 of the accompanying drawings, the actuator 19, cooperating with the pivoting support 16 of the drive shaft 3 'of the brush cylindrical 3, is constituted by an electric motor 21, conventional or step-by-step, reversible and / or provided with a reduction gear 22 controlled by the device 20 of automatic command and control of the position of the cylindrical brush 3, and by a mechanical device 23 for transforming the rotational movement of said electric motor 21 in movement movement of the cylindrical brush 3.

    Selon une autre caractéristique de l'invention, l'actionneur 19 peut être pourvu, en outre, d'une part, d'un dispositif de débrayage ou de désaccouplement (non représenté) entre le moteur électrique 21 et le dispositif mécanique 23 de transformation du mouvement de rotation du moteur électrique 21 en mouvement de déplacement de la brosse cylindrique 3, et, d'autre part, d'une commande manuelle 24 du déplacement de la brosse cylindrique 3 agissant sur le dispositif mécanique 23 de transformation du mouvement de rotation. Ainsi, le dispositif de désaccouplement peut être constitué par un moyen de déplacement de l'ensemble formé par le moteur électrique réversible 21, muni d'un réducteur 22 et du pignon ou de la roue 25, par rapport au pignon ou à la roue 26, de manière à les désolidariser. Bien entendu, il est également possible de réaliser ce dispositif de débrayage ou de désaccouplement sous forme d'un embrayage de type connu.According to another characteristic of the invention, the actuator 19 can be provided, on the one hand, with a declutching device or uncoupling (not shown) between the electric motor 21 and the device mechanical 23 for transforming the rotational movement of the electric motor 21 in movement of displacement of the cylindrical brush 3, and, on the other hand, of a manual control 24 of the displacement of the cylindrical brush 3 acting on the mechanical device 23 for transforming the rotational movement. So the uncoupling device can be constituted by a displacement means of the assembly formed by the reversible electric motor 21, provided with a reduction gear 22 and pinion or wheel 25, relative to pinion or wheel 26, so as to dissociate. Of course, it is also possible to make this device declutching or uncoupling in the form of a known type of clutch.

    Le dispositif mécanique 23 est constitué par un premier élément de transmission tel qu'un pignon, une roue ou une poulie 25, monté sur l'arbre de sortie du moteur électrique 21 et coopérant avec un deuxième élément de transmission tel qu'un pignon, une roue ou une poulie 26, et par une vis 27 d'actionnement en pivotement du support pivotant 16 de l'arbre d'entraínement 3' de la brosse cylindrique 3, assujettie en translation par rapport au bâti 18 par l'intermédiaire d'une butée 28 et coopérant avec un écrou 29 monté à articulation sur ledit support pivotant 16. Ainsi, par vissage ou dévissage de la vis 27 dans l'écrou 29, le support pivotant 16 est déplacé en pivotement suivant l'un ou l'autre sens de la double flèche F selon une trajectoire en arc de cercle rapprochant la brosse 3 du peigne cylindrique 2 ou l'écartant de ce dernier.The mechanical device 23 is constituted by a first element of transmission such as a pinion, a wheel or a pulley 25, mounted on the shaft of outlet of the electric motor 21 and cooperating with a second element of transmission such as a pinion, a wheel or a pulley 26, and by a screw 27 pivoting actuation of the pivoting support 16 of the drive shaft 3 ' of the cylindrical brush 3, subject in translation relative to the frame 18 by through a stop 28 and cooperating with a nut 29 mounted at articulation on said pivoting support 16. Thus, by screwing or unscrewing the screw 27 in the nut 29, the pivoting support 16 is pivotally displaced according to one or the other direction of the double arrow F according to a circular arc path bringing the brush 3 of the cylindrical comb 2 or moving it away from the latter.

    Bien entendu, le mode de réalisation du dispositif mécanique 23, tel que décrit ci-dessus, n'est donné qu'à titre d'exemple préférentiel, d'autres modes de réalisation de ce dispositif mécanique 23 peuvent être envisagés dans le cadre de la présente invention. Of course, the embodiment of the mechanical device 23, such as described above, is given only as a preferred example, other modes of this mechanical device 23 can be envisaged in the context of the present invention.

    Ainsi, conformément à une variante de réalisation de l'invention, représentée à la figure 2 des dessins annexés, le dispositif mécanique 23 peut également être constitué par une vis sans fin 27 entraínée par un moteur électrique 21 ou un moteur pas-à-pas réversible et engrenant avec un secteur denté 41 articulé sur un axe 42 solidaire du bâti 18, ledit secteur denté 41 entraínant le support pivotant 16 par l'intermédiaire d'un dispositif bielle 43-manivelle 44, d'un dispositif à excentrique ou d'une came.Thus, in accordance with an alternative embodiment of the invention, shown in Figure 2 of the accompanying drawings, the mechanical device 23 can also be constituted by a worm 27 driven by an electric motor 21 or a reversible stepping motor meshing with a toothed sector 41 articulated on an axis 42 integral with the frame 18, said toothed sector 41 driving the pivoting support 16 by means of a connecting rod 43-crank device 44, a eccentric or cam device.

    Du fait, d'une part, de la disposition géométrique de la brosse cylindrique 3 par rapport au peigne cylindrique 2 et au doffer 4 et, d'autre part, du fait de l'usure progressive de ladite brosse 3, le diamètre extérieur apparent de la brosse cylindrique 3 diminue progressivement et la valeur du déplacement angulaire du support pivotant 16 doit être progressivement augmentée de façon à maintenir une interpénétration constante ou quasi-constante des poils ou touffes de la brosse cylindrique 3.On the one hand, due to the geometric arrangement of the brush cylindrical 3 with respect to the cylindrical comb 2 and the doffer 4 and, on the other hand, due to the gradual wear of said brush 3, the apparent outside diameter of the cylindrical brush 3 gradually decreases and the displacement value angle of the pivoting support 16 must be gradually increased so as to maintain a constant or almost constant interpenetration of the hairs or tufts of the cylindrical brush 3.

    Un dispositif mécanique 23 ainsi constitué permet de transformer un mouvement uniformément circulaire du moteur électrique 21 ou du moteur pas-à-pas en un mouvement circulaire non uniforme de la position de l'arbre d'entraínement 3' par rapport à l'axe d'articulation 17. Ainsi, en fonction de la position angulaire de la bielle 43 et de son sens de rotation autour de l'axe 42, il est possible, pour chaque déplacement angulaire successif du moteur électrique 21 ou du moteur pas-à-pas d'augmenter ou de réduire chaque déplacement angulaire successif de l'arbre d'entraínement 3' autour de l'axe d'articulation 17.A mechanical device 23 thus formed makes it possible to transform a uniformly circular movement of the electric motor 21 or of the stepping motor in a non-uniform circular motion of the shaft position drive 3 'relative to the hinge axis 17. Thus, depending on the angular position of the connecting rod 43 and its direction of rotation about the axis 42, it is possible, for each successive angular displacement of the electric motor 21 or the stepper motor to increase or reduce each angular displacement of the drive shaft 3 'around the axis of articulation 17.

    Par ailleurs, afin d'assurer le positionnement du support pivotant 16 après son réglage par le moyen 8 de compensation automatique de l'usure de la brosse cylindrique 3, le dispositif selon la présente invention comporte, en outre. un ou plusieurs moyens 30 de maintien en position constitués par des moyens élastiques de blocage, tels qu'un empilement de rondelles élastiques ou un ressort, et par des moyens de déblocage, tels que des vérins pneumatiques ou hydrauliques agissant sur des surfaces de pression correspondantes du bâti 18 de la machine et du support pivotant 16. De tels moyens permettant le maintien de la brosse cylindrique 3 dans sa position d'arrêt de travail (figures 3 à 8).Furthermore, in order to ensure the positioning of the pivoting support 16 after its adjustment by means 8 of automatic compensation for wear of the cylindrical brush 3, the device according to the present invention further comprises. one or more means 30 for holding in position constituted by means blocking elastics, such as a stack of elastic washers or a spring, and by release means, such as pneumatic or hydraulic cylinders acting on corresponding pressure surfaces of the frame 18 of the machine and of the pivoting support 16. Such means allowing the maintenance of the brush cylindrical 3 in its work stop position (Figures 3 to 8).

    Selon une autre caractéristique de l'invention, et comme le montre la figure 11 des dessins annexés, le dispositif 20 de commande et de contrôle automatique de la position de la brosse cylindrique 3 du moyen 8 de compensation automatique de l'usure de la brosse cylindrique 3 comporte un asservissement programmable 32 réglant la périodicité et la valeur du déplacement de ladite brosse cylindrique 3, commandant le blocage en position du support pivotant 16 par l'intermédiaire des moyens 30 de maintien en position et fixant la vitesse de rotation de ladite brosse cylindrique 3, en fonction ou indépendamment de sa position, en commandant son entraínement par un moteur électrique 33 à vitesse variable. La liaison entre le moteur électrique 33 à vitesse variable et l'arbre d'entraínement 3' de la brosse cylindrique 3 peut être réalisé, de manière connue, au moyen de courroies, de pignons, ou de chaínes.According to another characteristic of the invention, and as shown in the Figure 11 of the accompanying drawings, the command and control device 20 automatic position of the cylindrical brush 3 of the compensation means 8 automatic wear of the cylindrical brush 3 includes a servo programmable 32 regulating the periodicity and the value of movement of said cylindrical brush 3, controlling the locking in position of the pivoting support 16 by means of means 30 for holding in position and fixing the speed of rotation of said cylindrical brush 3, as a function or independently of its position, by controlling its drive by an electric motor 33 at speed variable. The link between the variable speed electric motor 33 and the shaft drive 3 ′ of the cylindrical brush 3 can be produced, in known manner, using belts, sprockets, or chains.

    Conformément à une autre caractéristique de l'invention, le moyen 8 de compensation automatique de l'usure de la brosse cylindrique 3 peut être complété par des capteurs de position 34 contrôlant la position de l'arbre d'entraínement 3' de la brosse cylindrique 3 et/ou le diamètre efficace des poils ou touffes de la brosse cylindrique 3 et reliés à l'asservissement programmable 32, qui délivre en conséquence des ordres de réglage du support pivotant 16 et du moteur électrique 33 d'entraínement de l'arbre 3' d'entraínement de la brosse cylindrique 3.In accordance with another characteristic of the invention, the means 8 automatic compensation for the wear of the cylindrical brush 3 can be supplemented by position sensors 34 monitoring the position of the shaft drive 3 'of the cylindrical brush 3 and / or the effective diameter of the bristles or tufts of the cylindrical brush 3 and connected to the programmable servo 32, which consequently issues adjustment orders for the pivoting support 16 and the electric motor 33 for shaft drive 3 'brush drive cylindrical 3.

    Selon une variante de réalisation de l'invention, et comme le montrent les figures 5 et 6 des dessins annexés, le moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 peut être muni, en outre, sur le manchon de positionnement 7' du volant formant l'élément de manoeuvre, d'un palier 35 de montage coopérant avec un logement de guidage 36 d'une butée 38 solidaire du bâti 18 de la machine, ce palier 35 étant relié au manchon 7' par l'intermédiaire d'un roulement 37. Ainsi, le battement du moyen 7 peut être éliminé et le positionnement de la brosse 3 peut être parfaitement réalisé par rapport au peigne cylindrique 2.According to an alternative embodiment of the invention, and as the show Figures 5 and 6 of the accompanying drawings, the means 7 for disassembly, rapid reassembly and fixing of the cylindrical brush 3 can be provided, in in addition, on the positioning sleeve 7 ′ of the steering wheel forming the element of operation, of a mounting bearing 35 cooperating with a guide housing 36 a stop 38 integral with the frame 18 of the machine, this bearing 35 being connected to the sleeve 7 'by means of a bearing 37. Thus, the flapping of the means 7 can be eliminated and the positioning of the brush 3 can be perfectly achieved relative to the cylindrical comb 2.

    Dans un tel mode de réalisation, le logement de guidage 36 se présente, soit sous forme d'un logement curviligne correspondant à l'amplitude de déplacement de l'arbre d'entraínement 3', soit sous forme d'une plaque de guidage munie d'un évidement curviligne de réception du palier 35 et rapportée sur le bâti 18 de la machine, devant un trou de passage d'une ouverture de surface supérieure à celle du logement curviligne. Un moyen 7 ainsi équipé d'un palier 35 solidaire du volant de manoeuvre est démonté et monté de manière identique à un moyen 7 tel que décrit précédemment, le palier 35 accompagnant l'ensemble dans le mouvement d'extraction axiale et d'engagement axial de la brosse cylindrique 3.In such an embodiment, the guide housing 36 is present, either in the form of a curvilinear housing corresponding to the amplitude of displacement of the drive shaft 3 ', either in the form of a guide plate provided with a curvilinear recess for receiving the bearing 35 and attached to the frame 18 of the machine, in front of a through hole of an upper surface opening to that of the curvilinear housing. A means 7 thus equipped with an integral bearing 35 of the handwheel is disassembled and mounted identically to a means 7 as described above, the bearing 35 accompanying the assembly in the axial extraction and axial engagement movement of the cylindrical brush 3.

    Selon une autre caractéristique de l'invention, afin de garantir un positionnement correct continu de la brosse cylindrique 3, le moyen 8 de compensation automatique de l'usure de la brosse cylindrique 3 peut être pourvu, en outre, d'un dispositif de compensation du réglage et de maintien de l'extrémité de l'arbre porte-brosse, qui consiste, comme le montrent les figures 9 et 10 des dessins annexés, en une butée mobile 38 s'appuyant contre le palier 35 du moyen 7 de démontage, de remontage et de fixation rapides de la brosse cylindrique 3 et monté sur un levier 39 articulé à une extrémité sur le bâti 18 de machine et en un moyen 40 d'actionnement et de mise sous charge dudit levier 39, relié à l'autre extrémité de ce levier 39 et s'appuyant sur le bâti 18.According to another characteristic of the invention, in order to guarantee a continuous correct positioning of the cylindrical brush 3, the means 8 of automatic compensation for the wear of the cylindrical brush 3 can be provided, in addition, a device for compensating the adjustment and maintaining the end of the brush holder shaft, which consists, as shown in Figures 9 and 10 of attached drawings, in a movable stop 38 pressing against the bearing 35 of the means 7 quick disassembly, reassembly and fixing of the cylindrical brush 3 and mounted on a lever 39 articulated at one end on the machine frame 18 and in a means 40 for actuating and loading said lever 39, connected to the other end of this lever 39 and pressing on the frame 18.

    De préférence, le moyen 40 d'actionnement et de mise sous charge du levier 39 fonctionne par arc-boutement et est constitué par un levier 40' articulé à une extrémité sur le bâti 18 de la machine et coopérant à son autre extrémité avec une tringle 40'' de longueur variable sous charge reliée à l'extrémité libre du levier 39, le levier 40' du moyen 40 étant pourvu, par ailleurs, d'un moyen d'actionnement 40''', tel qu'une pédale, un levier ou autre, une butée 41 solidaire du bâti 18 limitant la course de basculement du levier 40'.Preferably, the means 40 for actuation and loading lever 39 operates by bracing and is constituted by an articulated lever 40 ' at one end on the frame 18 of the machine and cooperating at its other end with a 40 '' rod of variable length under load connected to the free end of the lever 39, the lever 40 'of the means 40 being provided, moreover, with a means actuator 40 '' ', such as a pedal, lever or other, a stop 41 secured of the frame 18 limiting the tilting stroke of the lever 40 '.

    Selon une autre caractéristique de l'invention, non représentée aux dessins annexés, le moyen 40 d'actionnement et de mise sous charge du levier 39 peut être pourvu, en outre, d'un élément amortisseur. Un tel élément amortisseur permet d'améliorer l'absorption du battement de l'arbre porte-brosse.According to another characteristic of the invention, not shown in attached drawings, the means 40 for actuating and loading the lever 39 may also be provided with a damping element. Such a damping element improves the absorption of the beat of the brush holder shaft.

    La tringle 40'' de longueur variable sous charge peut se présenter, comme le montrent les figures 9 et 10, sous forme d'un élément télescopique, dont l'une des parties constitutives est un fourreau de guidage de l'extrémité de l'autre partie, qui s'appuie sur l'extrémité correspondante de la première partie par l'intermédiaire d'un ressort de compression en butée contre une bague de retenue ou analogue de ladite deuxième partie.The rod 40 '' of variable length under load can be presented, as shown in FIGS. 9 and 10, in the form of a telescopic element, of which one of the constituent parts is a sleeve for guiding the end of the other part, which builds on the corresponding end of the first part by via a compression spring in abutment against a retaining ring or the like of said second part.

    Pour la mise en oeuvre du dispositif de compensation du réglage et de maintien de l'extrémité de l'arbre porte-brosse, il suffit, en partant de la position représentée à la figure 9, après mise en place du moyen 7 avec son palier 35, d'appuyer sur la pédale 40''' d'actionnement du levier 40' agissant sur la tringle 40'' de longueur variable sous charge. Cette dernière pousse alors sur le levier 39 portant la butée mobile 38 et applique celle-ci contre le palier 35. Pour assurer le maintien en position d'application de la butée mobile 38, le levier 40' est pivotée dans une position d'arc-boutement du moyen 40, dans laquelle l'axe d'articulation entre le levier 40' et le tringle 40'' a dépassé la position d'équilibre du moyen 40, constituée par la ligne passant par les axes d'articulation du levier 40' sur le bâti 18 et entre la tringle 40'' et le levier 39. Le levier 40' est en appui, dans cette position, contre la butée 41 solidaire du bâti 18.For the implementation of the adjustment compensation device and holding the end of the brush holder shaft, just from the position represented in FIG. 9, after the means 7 have been put in place with its bearing 35, to press the pedal 40 '' 'actuating the lever 40' acting on the rod 40 '' of variable length under load. The latter then pushes on the lever 39 carrying the movable stop 38 and applies it against the bearing 35. To ensure the holding the movable stop 38 in the application position, the lever 40 'is pivoted in a bracing position of the means 40, in which the axis of articulation between the lever 40 'and the rod 40' 'has exceeded the equilibrium position of the means 40, constituted by the line passing through the axes of articulation of the lever 40 'on the frame 18 and between the rod 40 '' and the lever 39. The lever 40 'is in support, in this position, against the stop 41 secured to the frame 18.

    Selon une variante de réalisation de l'invention, le moyen 40''' d'actionnement du levier 40' du moyen 40 d'actionnement et de mise sous charge du levier 39 peut également être constitué par un vérin agissant sur ledit levier 39 et dont l'enclenchement est assuré, soit automatiquement lors de la mise en marche de la machine, soit par l'intermédiaire d'un bouton de commande non représenté.According to an alternative embodiment of the invention, the means 40 '' ' actuation of the lever 40 'of the actuation and loading means 40 lever 39 can also be constituted by a jack acting on said lever 39 and whose engagement is ensured, either automatically upon activation machine running, either via a control button not represented.

    Une peigneuse rectiligne équipée d'un dispositif conforme à l'invention fonctionne de la manière suivante :A straight combing machine equipped with a device conforming to the invention operates as follows:

    La nappe de fibres entrantes 6 est peignée, d'une part, par le peigne cylindrique 2 et, d'autre part, par le peigne fixe 1. Les fibres courtes et les impuretés ainsi extraites de la nappe de fibres entrantes 6 forment la blousse, qui s'agglomère sur le peigne cylindrique 2. Ce dernier est déchargé de sa blousse et nettoyé par la brosse cylindrique de nettoyage 3. Cette opération de nettoyage du peigne cylindrique 2 est réalisée du fait que ledit peigne cylindrique 2 et la brosse cylindrique 3 tournent respectivement dans les sens de rotation indiqués à la figure 1. La brosse cylindrique 3 tourne plus rapidement que le peigne cylindrique 2. Le doffer 4 tournant également dans le sens de rotation indiqué à la figure 1, plus lentement que la brosse cylindrique 3, reprend la blousse et en est déchargé à son tour par le peigne détacheur 5 qui, par son mouvement oscillant, fait tomber ladite blousse dans un bac de récupération faisant partie de la peigneuse rectiligne. Le voile 6' obtenu, uniquement composé de fibres peignées longues, est alors reformé sur un manchon d'arrachage, condensé en ruban par un entonnoir et placé dans un pot. Le ruban peigné, réalisé à partir du voile 6', constitue le produit sortant de la peigneuse rectiligne.The sheet of incoming fibers 6 is combed, on the one hand, by the comb cylindrical 2 and, on the other hand, by the fixed comb 1. The short fibers and the impurities thus extracted from the sheet of incoming fibers 6 form the capsule, which agglomerates on the cylindrical comb 2. The latter is discharged from its cover and cleaned by the cylindrical cleaning brush 3. This cleaning operation of the cylindrical comb 2 is produced by the fact that said cylindrical comb 2 and the brush cylindrical 3 rotate respectively in the directions of rotation indicated in the figure 1. The cylindrical brush 3 rotates faster than the cylindrical comb 2. The doffer 4 also rotating in the direction of rotation indicated in figure 1, more slowly as the cylindrical brush 3, picks up the blister and is discharged from it turn by the detaching comb 5 which, by its oscillating movement, causes the said drop blousse in a drip tray that is part of the straight combing machine. The veil 6 'obtained, composed only of long combed fibers, is then reformed on a tear-off sleeve, condensed into ribbon by a funnel and placed in a pot. The combed tape, produced from the veil 6 ', constitutes the product leaving the straight combing machine.

    Pour réaliser une compensation de l'usure de la brosse cylindrique 3, le dispositif 20 de commande et de contrôle automatique de la position de la brosse cylindrique 3 délivre un signal de commande de lactionneur 19. Ce dernier déplace alors la brosse cylindrique 3 au moyen du support pivotant 16 de l'arbre d'entraínement 3' en direction du peigne cylindrique 2, afin que les poils ou touffes, dont elle est garnie, pénètrent entre les dents ou les aiguilles du peigne cylindrique 2, même s'ils sont courbés ou repliés, et les débarrassent complètement des fibres courtes et des impureté végétales qui les encombrent.To compensate for the wear of the cylindrical brush 3, the device 20 for automatic command and control of the position of the cylindrical brush 3 delivers an actuator control signal 19. The latter then moves the cylindrical brush 3 by means of the pivoting support 16 of the shaft drive 3 'towards the cylindrical comb 2, so that the bristles or tufts, with which it is garnished, penetrate between the teeth or the comb needles cylindrical 2, even if bent or folded, and clear them completely short fibers and vegetable impurities that clutter them.

    Grâce à l'invention, il est possible de compenser l'usure de la brosse cylindrique 3 en continu et automatiquement et d'améliorer l'ergonomie de ses manipulations. En effet, la brosse cylindrique 3 est constamment maintenue dans une position optimale par rapport au peigne cylindrique 2, qui est toujours bien débarrassé et nettoyé de la blousse. Le peigne cylindrique 2 étant propre en permanence, la maintenance de la peigneuse rectiligne est largement facilitée.Thanks to the invention, it is possible to compensate for the wear of the brush. cylindrical 3 continuously and automatically and improve the ergonomics of its manipulations. Indeed, the cylindrical brush 3 is constantly maintained in an optimal position in relation to the cylindrical comb 2, which is always good cleared and cleaned of the blister. The cylindrical comb 2 being clean in permanently, the maintenance of the straight combing machine is greatly facilitated.

    En outre, la propreté constante du peigne cylindrique 2 assure une meilleure qualité du travail de la peigneuse rectiligne, cette propreté constante étant également due au nettoyage très régulier du peigne cylindrique 2. En effet, ce dernier étant nettoyé d'une manière plus efficace, le produit sortant est automatiquement de meilleure qualité. Par ailleurs, le dispositif de maintien de l'extrémité de l'arbre porte-brosse permet d'éliminer le battement et de positionner parfaitement la brosse cylindrique par rapport au peigne cylindrique.In addition, the constant cleanliness of the cylindrical comb 2 ensures a better work quality of the straight combing machine, this constant cleanliness being also due to the very regular cleaning of the cylindrical comb 2. Indeed, this the latter being cleaned more efficiently, the outgoing product is automatically better. Furthermore, the device for maintaining the end of the brush holder shaft eliminates the flapping and positions perfectly the cylindrical brush compared to the cylindrical comb.

    De plus, par la compensation automatique de l'usure de la brosse cylindrique 3, cette dernière a une durée de vie prolongée et est, d'une manière générale, mieux exploitée. Par ailleurs, de nombreux arrêts de la machine sont évités, ce qui entraíne une contribution sensible à l'élévation du rendement de la peigne use rectiligne.In addition, by automatic brush wear compensation cylindrical 3, the latter has an extended service life and is, in a way general, better exploited. In addition, many machine stops are avoided, which leads to a significant contribution to raising the yield of the straight use comb.

    Enfin, le démontage et le remontage de la brosse cylindrique 3 étant facilités et accélérés, la durée d'arrêt de la machine pour retournement ou remplacement de la brosse cylindrique 3 est réduite, ce qui permet une augmentation du rendement de la machine et une réduction de la charge ouvrière supplémentaires.Finally, the disassembly and reassembly of the cylindrical brush 3 being facilities and accelerated, the downtime of the machine for overturning or replacement of the cylindrical brush 3 is reduced, which allows a increased machine efficiency and reduced workload additional.

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. 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 embodiments described and shown in the accompanying drawings. Modifications are still possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
