Description

La présente invention concerne une machine nappeuse de voiles de carde, qui comprend une pluralité de bandes continues associées à une pluralité de chariots déplaçables selon des mouvements alternatifs de va-et-vient, le mouvement du chariot déplaçable situé dans la partie inférieure déterminant le positionnement du voile de carde sur le convoyeur.The present invention relates to a machine for covering carding sails, which comprises a plurality of continuous bands associated with a plurality of carriages movable in reciprocating reciprocating movements, the movement of the movable carriage located in the lower part determining the positioning. card web on the conveyor.

ANTÉCÉDENTS DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaît des machines nappeuses qui comprennent plusieurs bandes continues associées à plusieurs chariots déplaçables selon des mouvements alternatifs de va-et-vient.Layer machines are known which comprise several continuous strips associated with several trolleys which can be moved in reciprocating back and forth movements.

Le voile de carde qui formera la nappe est disposé sur la bande située dans la partie supérieure de la machine, le mouvement du chariot associé à cette bande étant celui qui fera que les autres bandes se déplacent successivement. C'est le chariot situé dans la partie inférieure de la machine qui détermine le positionnement du voile de carde sur un convoyeur qui est sous la bande située dans la partie inférieure.The card web which will form the ply is placed on the strip located in the upper part of the machine, the movement of the carriage associated with this strip being that which will cause the other strips to move successively. It is the carriage located in the lower part of the machine which determines the positioning of the card web on a conveyor which is under the band located in the lower part.

Le mouvement alternatif de va-et-vient et l'avancement du convoyeur font que l'ensemble du convoyeur soit couvert par le voile de carde, formant la nappe.The reciprocating back and forth movement and the advancement of the conveyor means that the entire conveyor is covered by the card web, forming the sheet.

Pour contrôler la largeur et le grammage de la nappe dans ce type de machine nappeuse, le titulaire de la présente demande de brevet d'invention a conçu l'appareil décrit dans le brevet n° 8700989.To control the width and the grammage of the web in this type of coating machine, the holder of the present patent application designed the device described in patent n ° 8700989.

Cependant, ce type de machine nappeuse présente l'inconvénient qui consiste en ce que le voile de carde est découvert dans certaines parties de la machine, où l'air peut le lever du fait que le voile de carde est très léger.However, this type of lapping machine has the disadvantage that the card veil is uncovered in certain parts of the machine, where the air can lift it because the card veil is very light.

Si le voile de carde est levé dans certaines parties, lorsqu'il est placé sur le convoyeur, il risque d'être mal positionné et la nappe risque d'être irrégulière.If the card veil is lifted in some parts, when placed on the conveyor, it may be improperly positioned and the web may be irregular.

Pour éviter, dans la mesure du possible, que le voile de carde se lève, il faut que la vitesse des chariots déplaçables et du convoyeur soit très faible.To avoid, as far as possible, the carding veil lifting, the speed of the movable carriages and of the conveyor must be very low.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

La machine objet de l'invention réussi à résoudre les inconvénients mentionnés, et présente d'autres avantages qui seront décrits.The machine object of the invention succeeded in solving the drawbacks mentioned, and has other advantages which will be described.

La machine objet de l'invention se caractérise en ce qu'elle comprend une première et une seconde bandes continues situées sensiblement symétriques par rapport au plan longitudinal vertical de symétrie de la machine, les première et seconde bandes étant associées à un premier et un second chariots déplaçabales, le mouvement du premier chariot ou chariot inférieur déterminant le positionnement du voile de carde sur le convoyeur, le second chariot se déplaçant du fait de la tension des première et seconde bandes lorsque le premier chariot se déplace et dans le sens inverse à ce dernier, comprenant également une troisième bande continue associée à un troisième chariot situé entre les premier et second chariots, ce troisième chariot se déplaçant dans le même sens que le premier chariot, lesdites bandes étant situées très rapprochées entre elles pour conduire le voile de carde de la rainure supérieure définie entre les première et deuxième bandes à la rainure inférieure qui traverse le premier chariot, définie elle aussi par les première et seconde bandes.The machine object of the invention is characterized in that it comprises first and second continuous bands located substantially symmetrical with respect to the vertical longitudinal plane of symmetry of the machine, the first and second bands being associated with a first and a second movable trolleys, the movement of the first trolley or lower trolley determining the positioning of the card web on the conveyor, the second trolley moving due to the tension of the first and second belts when the first trolley moves and in the opposite direction to it last, also comprising a third continuous strip associated with a third carriage located between the first and second carriages, this third carriage moving in the same direction as the first carriage, said bands being located very close together to drive the card web the upper groove defined between the first and second strips at the ra lower edge which crosses the first carriage, also defined by the first and second bands.

Grâce à cette caractéristique, tout le parcours du voile de carde jusqu'à son positionnement sur le convoyeur se fait sous couvert, ce qui permet que celui-ci ne se lève pas et, de cette manière, la nappe reste uniforme. Cette caractéristique permet également que la vitesse des chariots et du convoyeur soit plus grande, ce qui permet d'obtenir un plus grand rendement dans la production de nappe.Thanks to this feature, the entire course of the card web to its positioning on the conveyor is done under cover, which allows it not to rise and, in this way, the web remains uniform. This feature also allows the speed of the carriages and the conveyor is larger, which allows a higher yield to be obtained in the production of groundwater.

Avantageusement, la machine nappeuse objet de l'invention comprend des moyens pour synchroniser le mouvement des premier et troisième chariots.Advantageously, the coating machine object of the invention comprises means for synchronizing the movement of the first and third carriages.

De préférence, les moyens pour synchroniser le mouvement des premier et troisième chariots sont deux courroies, chacune desquelles est raccordée sur un flanc de la machine et sur le premier chariot, et qui engrènent avec une troisième roue solidaire du troisième chariot, de sorte que le mouvement du premier chariot comporte le mouvement du troisième chariot dans le même sens.Preferably, the means for synchronizing the movement of the first and third carriages are two belts, each of which is connected to a side of the machine and to the first carriage, and which mesh with a third wheel secured to the third carriage, so that the movement of the first carriage involves movement of the third carriage in the same direction.

Avantageusement, le mouvement du premier chariot est actionné par un moteur.Advantageously, the movement of the first carriage is actuated by a motor.

Avantageusement, les première et seconde bandes passent autour d'un rouleau, ces deux rouleaux étant solidaires du troisième chariot, l'un de ces rouleaux étant raccordé au troisième chariot par une transmission qui fait tourner la troisième bande.Advantageously, the first and second strips pass around a roller, these two rollers being integral with the third carriage, one of these rollers being connected to the third carriage by a transmission which rotates the third strip.

Grâce à ces caractéristiques, c'est le moteur qui actionne le premier chariot qui déplace également le second et le troisième chariot. Comme on l'a dit, le second chariot est déplacé par l'action de la tension des première et seconde bandes, et le troisième chariot est déplacé par l'action des moyens de synchronisation cités.Thanks to these characteristics, it is the motor which actuates the first carriage which also moves the second and the third carriage. As said, the second carriage is moved by the action of the tension of the first and second bands, and the third carriage is moved by the action of the synchronization means mentioned.

Avantageusement, la machine nappeuse de l'invention comprend des moyens pour régler la tension de la première et deuxième bandes.Advantageously, the lapping machine of the invention comprises means for adjusting the tension of the first and second strips.

De préférence les moyens pour régler la tension des première et seconde bandes comprennent pour chacune d'elles une première plaque solidaire du bâti de la machine et une seconde plaque solidaire du support déplaçable sur lequel sont montés les rouleaux latéraux par lesquels la bande passe, et un mécanisme à vis et écrou agencé entre ces plaques.Preferably, the means for adjusting the tension of the first and second strips comprise, for each of them, a first plate secured to the frame of the machine and a second plate secured to the movable support on which the lateral rollers through which the strip passes are mounted, and a screw and nut mechanism arranged between these plates.

DESCRIPTION D'UNE RÉALISATION DE PRÉFÉRÉEDESCRIPTION OF A PREFERRED EMBODIMENT

Tel qu'on peut voir sur la figure 1, la machine nappeuse de l'invention comprend trois bandes continues 1, 2, 3, lesquelles sont symétriques par rapport à l'axe 4 lorsqu'elles se trouvent en position moyenne.As can be seen in Figure 1, the coating machine of the invention comprises three continuous strips 1, 2, 3, which are symmetrical with respect to the axis 4 when they are in the middle position.

Les première 1 et deuxième 2 bandes sont associées à un premier chariot 5 dans sa partie inférieure et à un second chariot 6 dans sa partie supérieure, tandis que la troisième bande 3 est associée à un troisième chariot 7.The first 1 and second 2 bands are associated with a first carriage 5 in its lower part and with a second carriage 6 in its upper part, while the third band 3 is associated with a third carriage 7.

Les première 1 et seconde 2 bandes passent autour d'une pluralité de rouleaux 8, 9, 10. Deux de ces rouleaux 8, ceux qui sont situés dans la partie central et supérieure de la machine, sont ceux qui actionnent le déplacement des bandes première 1 et seconde 2 sur les rouleaux 8, 9, 10 cités. Deux autres rouleaux 10, situés dans la partie supérieure de la machine mais à un niveau inférieur aux rouleaux actionneurs 8, sont associés au second chariot 6.The first 1 and second 2 bands pass around a plurality of rollers 8, 9, 10. Two of these rollers 8, those which are located in the central and upper part of the machine, are those which actuate the movement of the bands first 1 and second 2 on the rollers 8, 9, 10 mentioned. Two other rollers 10, located in the upper part of the machine but at a level below the actuator rollers 8, are associated with the second carriage 6.

Les première 1 et seconde 2 bandes passent également autour d'un rouleau 11, ces rouleaux 11 étant solidaires du troisième chariot 7. La troisième bande 3 passe elle aussi autour d'une paire de rouleaux 12, le pivotement de ces rouleaux 12 étant actionné à travers de l'un des rouleaux 11 par une courroie de transmission 13.The first 1 and second 2 bands also pass around a roller 11, these rollers 11 being integral with the third carriage 7. The third band 3 also passes around a pair of rollers 12, the pivoting of these rollers 12 being actuated through one of the rollers 11 by a transmission belt 13.

Les chariots 5, 6, 7 sont déplaçables en mouvements alternatifs de va-et-vient, le mouvement du premier chariot 5 déterminant le positionnement du voile de carde sur un convoyeur 14.The carriages 5, 6, 7 can be moved in reciprocating back-and-forth movements, the movement of the first carriage 5 determining the positioning of the card web on a conveyor 14.

Sur la figure 1 est représentée une position extrême des rouleaux 9, 10, 11, 12 en ligne continue, et en ligne discontinue est représentée l'autre position extrême.In Figure 1 is shown an end position of the rollers 9, 10, 11, 12 in a continuous line, and in a broken line is shown the other end position.

Le premier chariot 5 est actionné par un moteur (non représenté). Le mouvement du premier chariot 5 fait que le second chariot 6 soit également déplacé par la tension des première 1 et deuxième 2 bandes. Le mouvement du troisième chariot 7 est également produit par le mouvement du premier chariot 5, tel que décrit ci-dessous.The first carriage 5 is actuated by a motor (not shown). The movement of the first carriage 5 causes the second carriage 6 to also be displaced by the tension of the first 1 and second 2 bands. The movement of the third carriage 7 is also produced by the movement of the first carriage 5, as described below.

Sur la figure 2 on peut voir les moyens servant à synchroniser le mouvement des premier 5 et troisième 7 chariots. Il s'agit d'une paire de courroies 15 dont les extrémités sont raccordées respectivement au flanc du bâti de la machine 17 et au premier chariot 5. Sur la figure 2 on représente la même position extrême du premier chariot 5 que sur la figure 1.In Figure 2 we can see the means for synchronizing the movement of the first 5 and third 7 carriages. It is a pair of belts 15, the ends of which are respectively connected to the side of the frame of the machine 17 and to the first carriage 5. In FIG. 2 the same extreme position of the first carriage 5 is shown as in FIG. 1 .

La courroie 15 passe autour d'une roue 16 solidaire du premier chariot 5 et autour d'un rouleau 18. En même temps, la roue 16 est elle aussi solidaire du troisième chariot 7, ce qui fait que lorsque le premier chariot 5 de déplace, le troisième chariot 7 se déplace aussi dans le même sens de manière synchronisée.The belt 15 passes around a wheel 16 secured to the first carriage 5 and around a roller 18. At the same time, the wheel 16 is also secured to the third carriage 7, which means that when the first carriage 5 moves , the third carriage 7 also moves in the same direction in a synchronized manner.

Sur la figure 3 est représentée la machine nappeuse objet de l'invention, laquelle comprend sur ses deux flancs des moyens 18 servant à régler la tension des première 1 et seconde 2 bandes. Ce sont les moyens 18 représentés sur la figure qui règlent la tension de la première bande 1, tandis que sur le flanc opposé de la machine se trouvent les moyens 18 qui règlent la tension de la seconde bande 2.In Figure 3 is shown the coating machine object of the invention, which comprises on its two sides means 18 used to adjust the tension of the first 1 and second 2 bands. These are the means 18 shown in the figure which regulate the tension of the first band 1, while on the opposite side of the machine are the means 18 which regulate the tension of the second band 2.

Comme on peut voir sur la figure 4, les moyens 18 servant à régler la tension des première 1 et seconde 2 bandes comprennent pour chacune d'elles une première plaque 20 solidaire du bâti de la machine et une seconde plaque 21 solidaire d'un support déplaçable sur lequel sont montés les rouleaux latéraux 9 par lesquels la bande passe, et un mécanisme à vis 19 et écrou agencé entre ces plaques 20, 21.As can be seen in FIG. 4, the means 18 serving to adjust the tension of the first 1 and second 2 bands comprise for each of them a first plate 20 secured to the frame of the machine and a second plate 21 secured to a support movable on which are mounted the side rollers 9 through which the strip passes, and a screw mechanism 19 and nut arranged between these plates 20, 21.
