Description
Dispositivo para cortar películas de material flexible.Device for cutting material films flexible.
La presente invención se refiere al campo técnico de los dispositivos para cortar películas de material flexible, especialmente para dispositivos empleados en las máquinas de embalaje automático incluidas en la clasificación internacional B65b.The present invention relates to the technical field of devices for cutting films of flexible material, especially for devices used in machines automatic packaging included in the international classification B65b
Es conocido que en las máquinas de embalaje automático se emplean actualmente dispositivos de corte unidos a dispositivos de termosellado de películas de material flexible. Los dispositivos de corte, de más frecuente uso, tienen una cuchilla rectilínea es decir, en primer lugar, empujada de forma elástica para presionar las películas contra un elemento rígido y a continuación se golpea rápidamente para producir el corte instantáneo por medio de contraste con dicho elemento rígido. El corte rectilíneo resultante es estéticamente preferido al corte desigual que se obtiene con las cuchillas dentadas tradicionales.It is known that in packaging machines automatic cutting devices are currently used attached to Heat sealing devices of flexible material films. The cutting devices, most often used, have a blade rectilinear, that is, first, pushed in an elastic way to press the films against a rigid element and to then it hits quickly to produce the cut instantaneous by means of contrast with said rigid element. He resulting straight cut is aesthetically preferred to cut uneven obtained with serrated blades Traditional
Sin embargo, los dispositivos que realizan un corte rectilíneo brusco adolecen de dos inconvenientes. El primero de ellos es el ruido causado por los frecuentes batidos de la cuchilla contra el elemento de contraste rígido, el segundo es la utilización del borde de corte de la hoja rectilínea, que también es causado por el frecuente golpe de la cuchilla contra elementos rígidos.However, the devices that perform a abrupt straight cut suffer from two drawbacks. First of them is the noise caused by the frequent shakes of the blade against the rigid contrast element, the second is the use of the cutting edge of the rectilinear blade, which also it is caused by the frequent blow of the blade against elements rigid.
En las máquinas embaladoras más recientes el aumento de la productividad ha hecho que estos problemas sean más urgentes y es la combinación de ambos problemas lo que limita el empleo de los dispositivos de cuchillas rectilíneas de corte rápido.In the most recent packaging machines the Increased productivity has made these problems more urgent and it is the combination of both problems that limits the use of rectilinear cutting blade devices Quick.
El documento de extractos de patentes de Japón, vol. 1997, nº 07, de 31 de julio de 1997 (1997-07-31) da a conocer un dispositivo para el corte de una pluralidad de materiales en láminas, que utiliza un elemento de cuchilla que se baja verticalmente para entrar en contacto con la pluralidad de elementos de láminas substancialmente verticales. Para impedir un movimiento de un elemento de cuchilla en una dirección transversal a un plano de corte, estando el movimiento del elemento de cuchilla restringido en ambos lados por un soporte y un tope. De este modo, se mantiene un borde de corte en una posición vertical con respecto al material en láminas.The Japanese patent excerpts document, vol. 1997, No. 07, of July 31, 1997 (1997-07-31) unveils a device for cutting a plurality of materials in blades, which uses a blade element that is lowered vertically to come into contact with the plurality of elements of substantially vertical sheets. To prevent a movement of a blade element in a direction transverse to a plane cutting, the movement of the knife element being restricted on both sides by a support and a stop. In this way, it remains a cutting edge in a vertical position with respect to the material in sheets.
El documento DE 180480 C, que se considera representa la técnica anterior más próxima, da a conocer un aparato para cortar una pila de hojas de papel. Una barra prensora pesada es guiada verticalmente en un bastidor. Una barra de corte está dispuesta en paralelo con la barra prensadora y comprende bloques deslizantes que se insertan en hendiduras oblicuas en la barra prensadora. Un extremo de un muelle está unido a la barra prensadora y el otro extremo del muelle está unido a la barra de corte. En una posición de reposo, la barra prensadora sobresale desde la barra de corte. Si la disposición se desplaza verticalmente, es la barra prensadora la que entra en contacto con la hoja de papel superior de la pila en primer lugar. De este modo, la barra prensadora se detiene y presiona la pila contra un soporte, debido al peso de la barra prensadora. Además, la barra de corte se desplaza hacia abajo. Debido al movimiento relativo entre la barra prensadora y la barra de corte en la dirección vertical, la barra de corte se desplaza también horizontalmente, debido a que los bloques deslizantes son guiados mediante las hendiduras oblicuas. El muelle es comprimido tan pronto como el bloque prensador entra en contacto con la pila de papel, de modo que la fuerza prensadora puede hacerse constante sea cual sea la altura de la pila de papel.Document DE 180480 C, which is considered represents the closest prior art, discloses an apparatus to cut a stack of sheets of paper. A heavy press bar It is guided vertically in a rack. A cutter bar is arranged in parallel with the pressing bar and comprises blocks sliders that are inserted into oblique slits in the bar presser One end of a spring is attached to the bar presser and the other end of the spring is attached to the bar cut. In a rest position, the press bar protrudes from the cutter bar. If the layout moves vertically, it is the pressing bar that comes into contact with The top paper sheet of the stack first. In this way, the pressing bar stops and presses the battery against a support, due to the weight of the pressing bar. In addition, the bar cut shifts down. Due to the relative movement between the pressing bar and the cutting bar in the vertical direction, the cutter bar also moves horizontally, because the sliding blocks are guided by the slits oblique. The spring is compressed as soon as the block presser comes into contact with the stack of paper, so that the pressing force can be made constant regardless of the height of The stack of paper.

La solución propuesta por la presente invención mantiene las características estéticas de corte rectilíneo, pero elimina los problemas del ruido y del desgaste.The solution proposed by the present invention maintains the aesthetic characteristics of rectilinear cut, but Eliminates noise and wear problems.
La ventaja por esta invención industrial es obtener una operación de corte no ruidosa de máquinas embaladoras de alto rendimiento, al mismo tiempo que se extiende la duración del borde de corte de la cuchilla rectilínea.The advantage of this industrial invention is obtain a noisy cutting operation of packing machines high performance, while extending the duration of the cutting edge of the straight blade.
La realización de esta invención resulta aún más relevante cuando dichas mejoras se aplican durante el funcionamiento continuo a alta velocidad. Durante los ensayos intensivos, la reducción del ruido de la operación de corte y la duración del borde de corte de la cuchilla han resultado ser muy satisfactorios y especialmente válidos a alta velocidad.The realization of this invention is even more relevant when such improvements are applied during the continuous operation at high speed. During rehearsals intensive, noise reduction of the cutting operation and the duration of the cutting edge of the blade have proved to be very satisfactory and especially valid at high speed.
La invención se describe a continuación haciendo referencia a las figuras de los dibujos adjuntos. La Figura 1 representa, bajo una vista en planta en sección parcial, la estructura de un dispositivo de corte que consiste esencialmente en dos partes intermitentes opuestas. Se puede observar que el elemento de contraste 3, fácilmente intercambiable, se coloca mediante los muelles 2 sobre el cuerpo 1. Además, debe hacerse constar que el elemento del bloque de corte 8 está provisto de una cuchilla rectilínea 5, fácilmente intercambiable, sujetada por los muelles inclinados 7 contra dos pivotes elásticos 9 y 10.The invention is described below by making reference to the figures of the attached drawings. Figure 1 represents, under a partial plan view, the structure of a cutting device consisting essentially of two opposite intermittent parts. It can be seen that the contrast element 3, easily interchangeable, is placed by means of springs 2 on the body 1. In addition, it must be done it must be noted that the element of the cutting block 8 is provided with a straight blade 5, easily interchangeable, held by the inclined springs 7 against two elastic pivots 9 and 10.
Resulta particularmente importante la presencia del pequeño cilindro 4 unido a la cuchilla 5, que se sujeta por los muelles inclinados 7 contra el plano oblicuo 6, especialmente provisto en el cuerpo del bloque de corte 8. Debe aclararse que en la Figura 1 se ilustra el dispositivo de corte en la fase de reposo, es decir, en su posición abierta. La Figura 2 representa el dispositivo de aproximación y se puede observar que la cuchilla 5 ya no está en contacto con el elemento de contraste 3. La acción de corte no ha sido iniciada y la cuchilla se mantiene por los muelles 7 con un pequeño cilindro 4 en contacto con el plano oblicuo 6.The presence is particularly important of the small cylinder 4 attached to the blade 5, which is held by the inclined springs 7 against oblique plane 6, especially provided in the body of the cutting block 8. It should be clarified that in Figure 1 illustrates the cutting device in the phase of rest, that is, in its open position. Figure 2 represents the approach device and it can be seen that the blade 5 is no longer in contact with the contrast element 3. The action of cutting has not been initiated and the blade is held by the springs 7 with a small cylinder 4 in contact with the oblique plane 6.
La Figura 3 ilustra la fase de corte activa y se puede observar que la cuchilla 5, que entra en contacto con el elemento de contacto rígido 3, retrocede bajo la guía de los pivotes elásticos 9 y 10. Debe señalarse que, durante este movimiento de retroceso, la cuchilla se desliza también por las guías laterales debido a la presencia del cilindro 4 que se desliza sobre el plano oblicuo 6. La acción de corte se obtiene por el deslizamiento en las guías laterales de la cuchilla rectilínea que sucede sin choques y por lo tanto sin ruido, incluso en condiciones de alta velocidad.Figure 3 illustrates the active cutting phase and is You can see that the blade 5, which comes into contact with the rigid contact element 3, recedes under the guidance of the elastic pivots 9 and 10. It should be noted that, during this recoil movement, the blade also slides through the lateral guides due to the presence of the sliding cylinder 4 on the oblique plane 6. The cutting action is obtained by the sliding on the lateral guides of the rectilinear blade that it happens without shocks and therefore without noise, even in conditions Of high speed.
Resulta evidente que, después de haber realizado silenciosamente el corte, y antes de iniciar el siguiente ciclo, el dispositivo alcanzará de nuevo la posición de reposo ilustrada en la Figura 1.It is clear that, after having done silently cutting, and before starting the next cycle, the device will again reach the resting position illustrated in Figure 1.
Las Figuras 1bis, 2bis y 3bis representan una variación tecnológica, en la que el funcionamiento es básicamente similar al ilustrado en las Figuras 1, 2 y 3. Se puede observar la presencia de dos cilindros 4 y 4' y de los dos planos oblicuos 6 y 6' que accionan, en su recorrido de ida y retorno, el deslizamiento en las guías laterales de la cuchilla 5'. Se puede observar también que los muelles 7' no están tan inclinados como los muelles 7 y solamente se utilizan para mantener la cuchilla 5' en contacto con unos pivotes elásticos 9 y 10, que están insertados en el cuerpo del bloque de corte 8'. En la Figura 3bis, en particular, se puede observar que, durante el movimiento de retroceso, la cuchilla 5' realiza también un deslizamiento en las guías laterales, debido a la presencia del cilindro 4 que se desliza sobre el plano oblicuo 6 y realiza un corte sin ruido y sin choques. En la siguiente fase de apertura, la cuchilla expulsada hacia afuera por los pivotes elásticos 9 y 10 se retira a través de las guías laterales y no por los muelles 7' que no están inclinados, sino por el cilindro 4' que está acoplado contra el plano oblicuo 6' presente en el cuerpo del bloque de corte 8'.Figures 1bis, 2bis and 3bis represent a technological variation, in which the operation is basically similar to that illustrated in Figures 1, 2 and 3. You can see the presence of two cylinders 4 and 4 'and of the two oblique planes 6 and 6 'that drive, on their round trip, the slide on the side guides of the blade 5 '. It can also be observed that the springs 7 'are not as inclined as the springs 7 and they are only used to keep the blade 5 'in contact with elastic pivots 9 and 10, which are inserted in the body of cutting block 8 '. In Figure 3bis, in particular, you can note that, during the recoil movement, the blade 5 ' it also performs a slide in the lateral guides, due to the presence of the cylinder 4 that slides on the oblique plane 6 and Make a cut without noise and without shocks. In the next phase of opening, the blade ejected out by the pivots elastic 9 and 10 is removed through the side guides and not by the springs 7 'which are not inclined, but by the cylinder 4' which is coupled against the oblique plane 6 'present in the body of the 8 'cutting block.
