Description
Aparato para fabricar productos de papel multi-capa por moleteado Apparatus for manufacturing multi-layer paper products by knurling
[0001] La presente invención se refiere a un aparato para fabricar productos de papel multi-capa por moleteado. [0001] The present invention relates to an apparatus for manufacturing multi-layer paper products by knurling.
[0002] La invención se refiere, en particular, a los denominados productos de "papel tisú", tales como papel higiénico, pañuelos de papel, rollos de papel absorbente etc., constituidos por al menos dos capas. [0002] The invention relates, in particular, to the so-called "tissue paper" products, such as toilet paper, tissues, absorbent paper rolls etc., consisting of at least two layers.
[0003] Como se sabe, unir las capas de papel tisú mediante pasta produce una reducción de la suavidad del producto acabado. [0003] As is known, joining the layers of tissue paper with pulp produces a reduction in the smoothness of the finished product.
[0004] Para obviar este inconveniente, muchos productos de papel tisú en los que se requiere suavidad no se pegan con pasta sino que, en lugar de ello, se moletean. [0004] To avoid this inconvenience, many tissue paper products in which softness is required are not glued with pulp but instead are knurled.
[0005] Desafortunadamente, los sistemas de moleteado conocidos en la técnica tienen un inconveniente en que la parte de la capa que es deformada por las herramientas de moleteado tiene el aspecto de una línea que generalmente no está dispuesta simétricamente con respecto al producto. [0005] Unfortunately, knurling systems known in the art have a drawback in that the part of the layer that is deformed by the knurling tools has the appearance of a line that is generally not symmetrically disposed with respect to the product.
[0006] Esto siempre se ha considerado como un inconveniente estético, porque da al producto un aspecto "defectuoso". [0006] This has always been considered as an aesthetic inconvenience, because it gives the product a "defective" appearance.
[0007] El documento US-5622734 desvela un aparato para producir un laminado celulósico fibroso unido por corrugado que comprende una pluralidad de elementos de corrugado configurados en un patrón discontinuo, alineados en un eje que es paralelo al de la dirección transversal de mecanizado. Los elementos de corrugado están dispuestos en un lado de una barra de yunque, opuesta a un rodillo impulsor. [0007] US-5622734 discloses an apparatus for producing a corrugated bonded fibrous cellulosic laminate comprising a plurality of corrugated elements configured in a discontinuous pattern, aligned on an axis that is parallel to that of the transverse machining direction. The corrugated elements are arranged on one side of an anvil bar, opposite a drive roller.
[0008] El objetivo de la presente invención es proporcionar un aparato para fabricar productos de papel multi-capa por moleteado que superen los inconvenientes de la técnica anterior citada. [0008] The objective of the present invention is to provide an apparatus for manufacturing multi-layer paper products by knurling that overcome the drawbacks of the aforementioned prior art.
[0009] En un objeto particular de la invención es proporcionar un aparto que sea capaz de mantener características de alta suavidad del producto sin usar pasta y, al mismo tiempo, que pueda resolver las discontinuidades del moleteado convencional. [0009] In a particular object of the invention it is to provide an apparatus that is capable of maintaining high smoothness characteristics of the product without using paste and, at the same time, which can resolve the discontinuities of conventional knurling.
[0010] Un objeto adicional de la invención es proporcionar un aparato que permita producir las ruedas de moleteado por grabado y ataque por láser y, de esta manera, con costes reducidos. [0010] A further object of the invention is to provide an apparatus that allows to produce the knurling wheels by engraving and laser attack and, thus, with reduced costs.
[0011] Este objetivo y estos y otros objetos, que resultarán más evidentes en lo sucesivo en el presente documento, se consiguen mediante un aparato para fabricar productos de papel multi-capa de acuerdo con las reivindicaciones adjuntas. [0011] This objective and these and other objects, which will be more evident hereinafter, are achieved by means of an apparatus for manufacturing multi-layer paper products according to the appended claims.

[0013] Con referencia a las figuras citadas, un aparato de acuerdo con las técnica anterior, designando generalmente por el número de referencia 1, comprende un soporte 2 de rueda de moleteado que está constituido sustancialmente por un eje 3 que soporta una pluralidad de ruedas de moleteado 4, que actúan en contraste con un rodillo de contraste 5 para unir dos capas de papel en una sola cinta 6. [0013] With reference to the cited figures, an apparatus according to the prior art, generally designating by the reference number 1, comprises a knurling wheel support 2 that is substantially constituted by an axle 3 that supports a plurality of wheels knurling 4, which act in contrast to a contrast roller 5 to join two layers of paper on a single tape 6.
[0014] Las ruedas de moleteado 4 tienen dimensiones que son de seis a treinta y seis veces mayores que las de las ruedas de moleteado convencionales. A modo de ejemplo, aunque las ruedas de moleteado convencionales tienen un anchura comprendida entre 5 y 30 mm, la rueda de moleteado de acuerdo con la presente invención tiene una anchura de 181 mm. [0014] The knurling wheels 4 have dimensions that are six to thirty-six times larger than those of conventional knurling wheels. By way of example, although conventional knurling wheels have a width between 5 and 30 mm, the knurling wheel according to the present invention has a width of 181 mm.
[0015] La rueda de moleteado tiene un principio operativo que es similar al de una rueda de moleteado convencional pero, teniendo una superficie disponible mayor, permite crear decoraciones en relieve que después se transfieren al papel. [0015] The knurling wheel has an operating principle that is similar to that of a conventional knurling wheel but, having a larger available surface, allows to create embossed decorations that are then transferred to the paper.
[0016] Es evidente, a partir de los dibujos decorativos, que en el ejemplo ilustrado hay ondulaciones, que están dispuestas de manera que, a pesar de parecer separadas, permiten que la rueda de moleteado tenga un contacto continuo con el papel y el rodillo de contraste, evitando vibraciones que serían dañinas para el papel y para la rueda de moleteado. [0016] It is evident, from the decorative drawings, that in the illustrated example there are undulations, which are arranged so that, despite appearing separate, they allow the knurling wheel to have continuous contact with the paper and the roller. of contrast, avoiding vibrations that would be harmful to the paper and the knurling wheel.
[0017] La separación A entre cada dibujo permite decorar con continuidad en una dirección transversal a pesar de usar una pluralidad de rodillos de moleteado 4 en lugar de un solo rodillo. Todo esto es claramente beneficioso para las dimensiones de las ruedas de moleteado, que en el caso específico tienen un diámetro de 150 mm y, a pesar de las intensas presiones implicadas, no se flexionan, porque su dimensión transversal es 181 mm y, por lo tanto, es corta con respecto al diámetro. [0017] The separation A between each drawing allows to decorate continuously in a transverse direction despite using a plurality of knurling rollers 4 instead of a single roller. All this is clearly beneficial for the dimensions of the knurling wheels, which in the specific case have a diameter of 150 mm and, despite the intense pressures involved, do not flex, because their transverse dimension is 181 mm and, therefore, Therefore, it is short with respect to the diameter.
[0018] La distancia entre las ruedas de moleteado, designada por la letra de referencia B en la Figura 1, es tal que mantiene los dibujos 7 con una variación mínima de una rueda de moleteado a otra, lo que se refleja en el papel 6 como un diseño con efecto de continuidad. [0018] The distance between the knurling wheels, designated by the reference letter B in Figure 1, is such that it maintains the drawings 7 with a minimum variation from one knurling wheel to another, which is reflected in paper 6 as a design with continuity effect.
[0019] La rueda de moleteado se proporciona usando un material que es adecuado para experimentar grabado y ataque por láser y que, por lo tanto, tiene un bajo coste. [0019] The knurling wheel is provided using a material that is suitable for experiencing etching and laser attack and, therefore, has a low cost.
[0020] Con una disposición adecuada de los dibujos decorativos 7, siempre hay una decoración del rodillo que es capaz de ocultar las asimetrías. La continuidad del contacto entre el rodillo de contraste y la rueda de moleteado se mantiene también gracias a la anchura de la rueda de moleteado. [0020] With an adequate arrangement of decorative drawings 7, there is always a roller decoration that is able to hide the asymmetries. The continuity of the contact between the contrast roller and the knurling wheel is also maintained thanks to the width of the knurling wheel.
[0021] La Figura 9 ilustra una realización particular de los dibujos decorativos, designados por el número de referencia 17, que están caracterizados por la inserción, entre un diseño y el siguiente, de una serie de protuberancias 18 que permiten el contacto entre la rueda de moleteado y el rodillo de contraste, pero que no cambian el efecto final de la decoración, debido a que se combinan con el estampado del papel. [0021] Figure 9 illustrates a particular embodiment of the decorative drawings, designated by reference number 17, which are characterized by the insertion, between one design and the next, of a series of protuberances 18 that allow contact between the wheel of knurling and contrast roller, but they do not change the final effect of the decoration, because they are combined with the printing of the paper.
[0022] Usando un sistema con un cepillo cilíndrico contrarrotatorio, se asegura la limpieza eficaz de las ruedas de moleteado. [0022] Using a system with a counter-rotating cylindrical brush ensures effective cleaning of the knurling wheels.
[0023] Además, el aparato permite proporcionar una decoración sobre una base estampada existente usando una rueda de moleteado en la que las protuberancias son mayores que las protuberancias de la base. [0023] In addition, the apparatus allows to provide a decoration on an existing stamped base using a knurling wheel in which the protuberances are larger than the protuberances of the base.
[0024] Las Figuras 5 y 6 ilustran una realización del aparato, designado por el número de referencia 101, de acuerdo con la invención. [0024] Figures 5 and 6 illustrate an embodiment of the apparatus, designated by reference number 101, in accordance with the invention.
[0025] Debido a las intensas fuerzas generadas por el empuje de las ruedas de moleteado 4 contra el rodillo de contraste 5, el rodillo de contraste 5 puede flexionarse durante la rotación, reduciendo la cohesión de las capas de papel. [0025] Due to the intense forces generated by the thrust of the knurling wheels 4 against the contrast roller 5, the contrast roller 5 can flex during rotation, reducing cohesion of the paper layers.
[0026] Para obviar este inconveniente, es posible aumentar el diámetro del rodillo de contraste 5 para aumentar su resistencia a flexión, aunque esto conduce a altos costes. [0026] To avoid this inconvenience, it is possible to increase the diameter of the contrast roller 5 to increase its resistance to bending, although this leads to high costs.
[0027] Para evitar generar estos costes y evitar aumentos adicionales en la complejidad de la máquina, las ruedas de moleteado 4 pueden hacerse funcionar en direcciones mutuamente opuestas en el mismo rodillo de contraste 5, de manera que cancelan la torsión. Con tal disposición puede variarse libremente la distancia B según se desee. [0027] To avoid generating these costs and avoid further increases in machine complexity, the knurling wheels 4 can be operated in mutually opposite directions on the same contrast roller 5, so that they cancel the torsion. With such an arrangement, the distance B can be freely varied as desired.
5 [0028] En el ejemplo ilustrado, a modo de indicación, la distancia entre las ruedas de moleteado 4 en el mismo eje es de aproximadamente 210 mm. [0028] In the illustrated example, by way of indication, the distance between the knurling wheels 4 on the same axle is approximately 210 mm.
[0029] Las ruedas de moleteado 4 pueden estar soportadas por un solo eje de soporte, como se ha descrito anteriormente, o individualmente por un soporte para cada rueda de moleteado, como se muestra 10 esquemáticamente en la Figura 6, que ilustra ruedas de moleteado 4 individuales, una de las cuales está soportada por un soporte 44 aplicado a una viga de soporte 14. [0029] The knurling wheels 4 can be supported by a single support shaft, as described above, or individually by a support for each knurling wheel, as schematically shown in Figure 6, which illustrates knurling wheels. 4 individual, one of which is supported by a support 44 applied to a support beam 14.
[0030] Una almohadilla inflable 8 está interpuesta, preferentemente, entre las ruedas de moleteado 4 y la viga de soporte 14. [0030] An inflatable pad 8 is preferably interposed between the knurling wheels 4 and the support beam 14.
15 [0031] Las Figuras 7 y 8 ilustran una realización adicional del sistema de soporte de ruedas de moleteado de un solo eje, en el que las ruedas de moleteado 4 están asociadas con el eje 3, que es empujado en sus dos extremos por brazos eléctricos 10. [0031] Figures 7 and 8 illustrate a further embodiment of the single-axis knurling wheel support system, in which knurling wheels 4 are associated with axis 3, which is pushed at its two ends by arms electric 10.
20 [0032] Los brazos eléctricos 10 actúan sobre una viga 11, que incluye una serie de soportes intermedios 9 para el eje 3, que evitan la flexión del eje. [0032] The electric arms 10 act on a beam 11, which includes a series of intermediate supports 9 for the axis 3, which prevent the shaft from flexing.
[0033] En la práctica, se ha descubierto que la invención consigue los objetivos y objetos pretendidos, proporcionando un aparato que es capaz de mantener altas características de suavidad del producto sin usar un 25 adhesivo y, al mismo tiempo, resolviendo el problema estético del moleteado convencional. [0033] In practice, it has been found that the invention achieves the intended objectives and objects, providing an apparatus that is capable of maintaining high softness characteristics of the product without using an adhesive and, at the same time, solving the aesthetic problem of the conventional knurling.
[0034] El aparato de acuerdo con la invención une dos o más capas de papel tisú y simultáneamente las decora mediante la impresión dejada por la herramienta de moleteado. [0034] The apparatus according to the invention joins two or more layers of tissue paper and simultaneously decorates them by printing left by the knurling tool.
30 [0035] El aparato permite que las capas pasen entre el rodillo de contraste y una serie de ruedas de moleteado, que están decoradas apropiadamente en relieve y que son adecuadas, mediante la presión aplicada a un rodillo de contraste, para unir las capas que están interpuestas entre el rodillo de contraste y la unidad de rueda de moleteado. [0035] The apparatus allows the layers to pass between the contrast roller and a series of knurling wheels, which are appropriately decorated in relief and which are suitable, by the pressure applied to a contrast roller, to join the layers that they are interposed between the contrast roller and the knurling wheel unit.
[0036] El aparato de acuerdo con la invención permite unir las capas de papel y, al mismo tiempo, decorarlas 35 usando la técnica de deformación permanente del papel, que gracias a la deformación también asume una coloración e impresión diferentes y permite reconocer el dibujo decorativo. [0036] The apparatus according to the invention allows the paper layers to be joined and, at the same time, to decorate them using the permanent paper deformation technique, which, thanks to the deformation, also assumes a different coloring and printing and allows the drawing to be recognized decorative.
[0037] Otra característica de la invención consiste en la disposición particular del dibujo decorativo a lo largo de la circunferencia y en la dirección transversal de la rueda decorada.
