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 coating machine of card webs, which includes a plurality of bands continuous associated with a plurality of movable carriages in reciprocating back and forth movements, the movement of the movable carriage located in the part lower determining the positioning of the card web on the conveyor.

ANTÉCÉDENTS DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaít des machines nappeuses qui comprennent plusieurs bandes continues associées à plusieurs chariots déplaçables selon des mouvements alternatifs de va-et-vient.We know tablecloth machines which include several continuous bands associated with several trolleys displaceable 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 that will form the web is arranged on the strip located in the upper part of the machine, the movement of the carriage associated with this band being that which will cause the other bands to move successively. It is the carriage located in the lower part of the machine that determines the positioning of the card web on a conveyor which is under the band located in the part lower.

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 either covered by the card veil, forming the web.

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 grammage of the tablecloth 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 coating machine has the downside is that the card web is discovered in certain parts of the machine where the air can lift it due to the fact that 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 risks to be badly positioned and the tablecloth is likely to 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, that the carding veil lifts, the speed of the carriages and the conveyor is very small.

La demande de brevet EP-A-0 609 907 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, qui comprend une première et une seconde bandes continues, 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, 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.Patent application EP-A-0 609 907 relates to a carding machine, which includes a plurality of continuous bands associated with a plurality of trolleys movable in reciprocating movements of back and forth, the movement of the movable carriage located in the lower part determining the positioning of the veil carding on the conveyor, which includes a first and a second continuous bands, the first and second bands being associated with first and second carriages displacabales, the movement of the first cart or cart lower determining the positioning of the card web on the conveyor, the second carriage moving due to the tension of the first and second bands when the first carriage moves and in reverse to this last, also including a third continuous strip associated with a third carriage located between the first and second carriages, said bands being located very close together to drive the carded veil of the upper groove defined between the first and second bands at the bottom groove 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 route of the card web until it is positioned on the conveyor is done under cover, which allows it to not rise not and, in this way, the sheet remains uniform. This characteristic also allows that the speed of trolleys and conveyor is larger, allowing to obtain a higher yield in the production of tablecloth.

Néanmoins cette machine présente quelques inconvénients.However, this machine has some disadvantages.

Premièrement, les bandes ne sont pas symétriques et la rainure supérieure d'introduction du matériel n'a pas une position fixe, ce qui permet seulement l'alimentation par un seul côté.First, the bands are not symmetrical and the upper material insertion groove has not a fixed position, which only allows feeding by one side only.

Deuxièmement, dans le parcours du voile de carde à travers de la machine ils y a des points de coincement, ce qui provoque des étirages du voile de carde qui doivent se compenser par la régulation de vitesse des chariots.Second, in the course of the carding veil across the machine there are sticking points, this which causes stretching of the carding veil which must be compensate by the speed regulation of the carriages.

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 successfully solved the disadvantages mentioned, and presents other advantages which will be described.

La machine objet de l'invention se caractérise en ce que la première et la seconde bandes continues sont symétriques par rapport au plan longitudinal vertical de la machine lorsqu'elles se trouvent en position moyenne, et en ce que la position de la rainure supérieure est fixe.The machine object of the invention is characterized by what the first and second continuous bands are symmetrical with respect to the vertical longitudinal plane of the machine when they are in the middle position, and that the position of the upper groove is fixed.

Dans la demande, la symétrie des bandes et la position fixe de la rainure supérieure A permet l'alimentation de la machine par les deux côtés, ce qui comporte de doubler la production en obtenant une voile de carde de gramage uniforme.In the application, the symmetry of the bands and the fixed position of the upper groove A allows feeding the machine from both sides, which involves doubling production by obtaining a sail of uniform weight card.

Avantageusement, la machine nappeuse objet de l'invention comprend deux rouleaux solidaires du troisième chariot avec un diamètre supérieur au diamètre des rouleaux de la troisième bande et elle comprend en plus deux paires de rouleaux dans la rainure supérieure et deux paires de rouleaux dans la rainure inférieure. Advantageously, the coating machine object of the invention comprises two rollers integral with the third carriage with a diameter greater than the diameter of the rollers of the third band and it also includes two pairs rolls in the upper groove and two pairs of rollers in the lower groove.

De cette façon on obtient un voile de carde sans coincements, et par conséquent, sans étirages et de gramage uniforme. In this way we obtain a card veil without jams, and therefore without stretching and uniform grammage.

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 carts are two belts, each of which is connected to a side of machine and on the first carriage, and which mesh with a third wheel secured to the third carriage, so that the movement of the first carriage includes the 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 powered 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 bands pass around a roll, these two rolls being integral with the third carriage, one of these rollers being connected to the third carriage by a transmission which makes turn 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 engine that operates the first cart which also moves the second and the third cart. As we said, the second cart is moved by the action of the tension of the first and second strip, and the third carriage is moved by the action of the cited synchronization means.

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

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 bands include for each of them a first plate secured to the machine frame and a second plate secured to the movable support on which side rollers are mounted by which the strip pass, and a screw and nut mechanism arranged between these plates.

    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 machine tablecloth of the invention comprises three continuous strips 1, 2, 3, which are symmetrical about 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 to a first carriage 5 in its lower part and to a second carriage 6 in its upper part, while the third strip 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 of a plurality of rollers 8, 9, 10. Two of these rollers 8, those located in the central and upper part of the machine, are those which actuate the displacement of bands first 1 and second 2 on rollers 8, 9, 10 cited. Two other rollers 10, located in the part upper part of the machine but at a level lower than 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.
