Description
DESCRIPCIÓNDESCRIPTION
Dispositivo de corte transversal para una máquina bobinadoraCross cutting device for a winding machine
La presente invención se refiere a un dispositivo de separación transversal o corte transversal para una máquina bobinadora para el enrollado de un material con forma de banda, preferentemente una banda de material de fibras o de material no tejido, con un agente de separación transversal o corte transversal para el corte o separación de la banda de material al finalizar la operación de enrollado según el preámbulo de la reivindicación 1.The present invention relates to a transverse separating or transverse cutting device for a winding machine for winding a web-shaped material, preferably a web of fiber material or non-woven material, with a transverse separating or cutting agent. cross section for cutting or separating the web of material at the end of the winding operation according to the preamble of claim 1.
En la fabricación de una banda de material de fibras textiles o no textiles, esta es enrollada al final de la instalación en un bobinador por medio de un eje de enrollamiento. Si el rollo de material alcanza un diámetro definido, la banda de material se corta por medio de una cuchilla o, alternativamente, por medio de un dispositivo de separación transversal o corte transversal y el rollo de material se transfiere a una posición de espera o de almacenamiento. El dispositivo de corte transversal comprende por regla general una cuchilla rotativa que puede desplazarse transversalmente a la banda de material y la corta. Para que, durante el corte, la banda de material no se pueda mover, un pisador coopera con la cuchilla. Con ello se garantiza que la banda de material se sumerja forzosamente en la cuchilla rotativa y, con ello, sea cortada.In the manufacture of a web of textile or non-textile fiber material, it is wound at the end of installation on a winder by means of a winding shaft. If the roll of material reaches a defined diameter, the web of material is cut by means of a knife or, alternatively, by means of a transverse separation or cross-cut device and the roll of material is transferred to a waiting or waiting position. storage. The transverse cutting device generally comprises a rotating blade that can be moved transversely to the web of material and cuts it. So that, during cutting, the material web cannot move, a hold-down cooperates with the blade. This ensures that the material web is forced into the rotating knife and is thereby cut off.
Si el filo de la cuchilla se desgasta, la banda de material se puede atascar entre la cuchilla rotativa y el pisador, de tal modo que, debido a las fuerzas que se generan, el pisador puede romperse, lo que puede provocar un daño adicional del dispositivo de corte transversal.If the cutting edge of the knife wears, the web of material can get jammed between the rotating knife and the platen, such that due to the forces that are generated, the platen can break, which can cause additional damage to the platen. cross cutting device.
El documento JP 63-182898 desvela un equipo de corte transversal pivotante con un pisador instalado de manera estacionaria en el dispositivo de corte transversal.JP 63-182898 discloses a pivoting crosscutting equipment with a plunger installed stationary in the crosscutting device.
La invención se basa, por tanto, en el objetivo de mejorar el dispositivo de corte transversal de tal modo que se impida un atasco de la banda de material y un daño del dispositivo.The invention is therefore based on the object of improving the transverse cutting device in such a way as to prevent a jamming of the web of material and damage to the device.
La solución para este objetivo se consigue por medio de las características de la reivindicación 1.The solution to this objective is achieved by means of the features of claim 1.
La invención incluye la enseñanza técnica de que el dispositivo de corte transversal para una máquina bobinadora se extiende transversalmente a la dirección de transporte de una banda de material y está configurado para pivotar para la operación de corte de la banda de material desde una posición de reposo al menos parcialmente hacia el interior del plano de la banda de material. A este respecto, el dispositivo de corte transversal comprende al menos una cuchilla que está dispuesta de manera desplazable a lo largo de una guía ortogonalmente a la dirección de transporte de la banda de material. La cuchilla coopera durante la operación de corte de manera continua con un pisador. Si se forma entre la cuchilla y el pisador un atasco de material, de acuerdo con la invención el pisador está configurado para desplazarse de una posición de funcionamiento a una posición de desviación. Así se evita una rotura del pisador, lo que puede provocar un daño adicional del dispositivo de corte transversal.The invention includes the technical teaching that the cross cutting device for a winding machine extends transversely to the conveying direction of a web of material and is configured to pivot for the operation of cutting the web of material from a rest position. at least partially into the plane of the web of material. In this regard, the transverse cutting device comprises at least one blade that is displaceably arranged along a guide orthogonal to the conveying direction of the web of material. The blade cooperates during the cutting operation continuously with a hold-down. If a material jam forms between the blade and the plunger, according to the invention the plunger is configured to move from an operating position to a deflection position. This prevents breakage of the clamp, which can cause additional damage to the cross-cutting device.
A este respecto, la cuchilla está configurada como cuchilla rotativa y el pisador está dispuesto de manera que puede pivotar en torno a un punto de rotación de la cuchilla. En caso de un atasco de material, el pisador desvía por medio de un movimiento pivotante las fuerzas generadas debido al movimiento de desplazamiento transversalmente a la banda de material.In this regard, the blade is configured as a rotary blade and the hold-down is arranged so that it can pivot about a point of rotation of the blade. In the event of a material jam, the clamp deflects the forces generated by the displacement movement transversely to the material web by means of a pivoting movement.
Preferentemente, el pisador está dispuesto en una brida que coopera con una sujeción dispuesta paralelamente a la cuchilla. El movimiento pivotante del pisador es, por tanto, independiente de la rotación de la cuchilla, de tal modo que esta puede cortar libremente el atasco de material sin el pisador, o la banda de material es guiada sobre la cuchilla sin cortar, si la cuchilla está desafilada. Así se evita una acumulación adicional del material.Preferably, the plunger is arranged on a flange that cooperates with a clamp arranged parallel to the blade. The pivoting movement of the platen is therefore independent of the rotation of the blade, so that the blade can freely cut the material jam without the platen, or the web of material is guided over the uncut blade, if the blade it is dull. This prevents additional accumulation of the material.
La sujeción presenta una ranura con forma de arco circular en la que penetra un elemento guía de la brida. Así se limita el movimiento pivotante de la brida y, por lo tanto, del pisador. Al presentar la brida un dispositivo de enclavamiento cargado por resorte que mantiene la brida con el pisador en posición de funcionamiento, en caso de fluctuaciones en el grosor de material y la resistencia del material, se puede evitar un pivotado demasiado temprano del pisador a la posición de desviación.The clamp has a circular arc-shaped groove into which a guide element of the flange penetrates. This limits the pivoting movement of the flange and, therefore, of the hold-down. By presenting the flange with a spring-loaded interlocking device that holds the flange with the platen in the operating position, in the event of fluctuations in material thickness and material strength, too early pivoting of the platen to the position can be avoided. deviation.
Preferentemente, la carga por resorte del dispositivo de enclavamiento se puede regular, de tal modo que es posible una adaptación del movimiento pivotante a diferentes bandas de material (grosor, material, etc.).Preferably, the spring load of the locking device can be adjusted, so that an adaptation of the pivoting movement to different material bands (thickness, material, etc.) is possible.
Solo en caso de superarse las fuerzas de resorte, se libera el dispositivo de enclavamiento y la brida con el pisador pivota a la posición de desviación.Only if the spring forces are exceeded, the interlocking device is released and the flange with the plunger pivots to the deflection position.
Preferentemente, la brida con el pisador puede estar configurada de manera pivotante manual o automáticamente desde la posición de desviación a la posición de funcionamiento. Tanto el pivotado automático como el pivotado manual desde la posición de desviación a la posición de funcionamiento por medio de una palanca impide una lesión del usuario por medio de la hoja de la cuchilla. Preferably, the flange with the plunger may be pivotally configured manually or automatically from the offset position to the operating position. Both automatic pivoting and manual pivoting from the offset position to the operating position by means of a lever prevents injury to the user by means of the knife blade.
Se puede conseguir otra automatización por medio de un sensor que determine la posición del pisador y/o de la brida sobre una extensión parcial de la sujeción. Esto puede ser usado para advertir al usuario y/o detener la máquina si es necesario.Further automation can be achieved by means of a sensor that determines the position of the plunger and / or the flange over a partial extension of the clamping. This can be used to warn the user and / or stop the machine if necessary.

La figura 1 muestra una máquina bobinadora 1 con el equipo de corte transversal 10 de acuerdo con la invención. La máquina bobinadora 1 se sitúa con la zona de entrada 2 al final de una instalación en la que se fabrican a partir de fibras telas no tejidas o productos no tejidos. Una banda de material no referenciada entra por medio de la zona de entrada 2 en la máquina bobinadora 1 y es enrollada en un eje de enrollamiento 4 hasta convertirse en un rollo, no representado. El eje de enrollamiento 4 se muestra en posición de reserva. Por encima de un rodillo de contacto 5, que refuerza la operación de enrollado, se representa un dispositivo de corte transversal 10 que se describe en detalle en las siguientes figuras. A través de la zona de descarga 3, el rollo terminado es transportado tras la separación de la restante banda de material a un depósito intermedio o final.Figure 1 shows a winding machine 1 with the cross cutting equipment 10 according to the invention. The winding machine 1 is located with the input zone 2 at the end of an installation in which non-woven fabrics or non-woven products are manufactured from fibers. A non-referenced material web enters the winding machine 1 through the input zone 2 and is wound on a winding shaft 4 until it becomes a roll, not shown. Winding shaft 4 is shown in reserve position. Above a contact roller 5, which reinforces the winding operation, a transverse cutting device 10 is represented which is described in detail in the following figures. Through the discharge zone 3, the finished roll is transported after the separation of the remaining material web to an intermediate or final deposit.
Las figuras 2 y 3 muestran en una vista ampliada el dispositivo de corte transversal 10, que se extiende transversalmente sobre el rodillo de contacto 5 y puede pivotar (flecha) por medio de la brida 11 montada de manera giratoria en torno al eje de rotación del rodillo de contacto 5 hacia el interior de la banda de material tensada. En esta representación el dispositivo de corte transversal 10 se encuentra en posición de espera hasta que el rollo está terminado de enrollar. Tras una longitud de enrollamiento predeterminada, el dispositivo de corte transversal 10 pivota al plano de la banda de material, encontrándose la cuchilla 13 lateralmente fuera de la banda de material y encontrándose por debajo del plano de la banda de material. Con el movimiento de corte, la cuchilla 13 se desplaza lateralmente a la banda de material y la corta. Un pisador 14 con forma de cuña se encuentra por encima del plano de la banda de material, de tal modo que esta se encuentra entre la cuchilla 13 y el pisador 14 y es cortada mediante la rotación y movimiento transversal de la cuchilla sobre la banda de material. Dentro del dispositivo de corte transversal 10 está dispuesta una guía lineal 12 a lo largo de la cual la cuchilla 13 es guiada de manera accionada transversalmente sobre la banda de material y corta la banda de material. La cuchilla 13 está dispuesta en un ángulo de 30° a 60° con respecto al eje longitudinal del rodillo de contacto 5, dependiendo el tamaño del ángulo, entre otras cosas, de la velocidad de enrollado, para lograr una corte lo más rectangular posible con respecto a la dirección de enrollado.Figures 2 and 3 show in an enlarged view the transverse cutting device 10, which extends transversely over the contact roller 5 and can be pivoted (arrow) by means of the flange 11 mounted in a rotatable manner about the axis of rotation of the contact roller 5 into the tensioned material web. In this representation, the cross-cutting device 10 is in the waiting position until the roll is finished winding. After a predetermined winding length, the transverse cutting device 10 pivots to the plane of the material web, the blade 13 being laterally outside the material web and lying below the plane of the material web. With the cutting movement, the blade 13 moves laterally to the web of material and cuts it. A wedge-shaped hold-down 14 is located above the plane of the material web, in such a way that it is located between the blade 13 and the hold-down 14 and is cut by the rotation and transverse movement of the blade on the web of material. material. Inside the cross cutting device 10 a linear guide 12 is arranged along which the blade 13 is guided transversely on the web of material and cuts the web of material. The blade 13 is arranged at an angle of 30 ° to 60 ° with respect to the longitudinal axis of the contact roller 5, the size of the angle depending, among other things, on the winding speed, to achieve a cut as rectangular as possible with with respect to the winding direction.
La figura 4 muestra una representación ampliada de una parte del dispositivo de corte transversal 10 en la que se ha retirado el revestimiento 15 del lado delantero y del lado trasero. La cuchilla 13 está configurada como cuchilla rotativa que es puesta en rotación por medio de un accionamiento 17 motor o neumático. La cuchilla 13 está instalada de manera giratoria en un bastidor 16 en el que también está dispuesto de manera resistente al giro el accionamiento 17. Entre la cuchilla 13 y el accionamiento 17 está dispuesta una sujeción 18 para el pisador 14, que puede pivotar al menos parcialmente en torno a esta sujeción 18. Para ello, el pisador 14 está fijado en una brida 20 que está guiada con un elemento guía 21, en este caso no reconocible, en una ranura 19 de la sujeción 18 en una trayectoria circular. En posición de funcionamiento, cuando la cuchilla 13 corta la banda de material, el pisador 14 se encuentra en esta posición superior, encontrándose la brida 20 con el elemento guía 21 en el tope superior de la ranura 19. El pisador 14 es sujetado en esta posición con la brida 20 por medio de elementos de resorte no representados. Los elementos de resorte están configurados de manera regulable para poder variar las fuerzas de enclavamiento para esta posición. Según el estado de la técnica, una cuchilla 13 desafilada provocaba un atasco de material, debido a lo cual a menudo se producía una rotura del pisador 14.Figure 4 shows an enlarged representation of a part of the cross-cutting device 10 in which the liner 15 has been removed from the front side and the rear side. The blade 13 is configured as a rotary blade which is set in rotation by means of a motor or pneumatic drive 17. The blade 13 is rotatably installed on a frame 16 in which the drive 17 is also arranged in a rotationally resistant manner. Between the blade 13 and the drive 17 there is arranged a holder 18 for the plunger 14, which can be pivoted at least partially around this clamp 18. For this, the plunger 14 is fixed on a flange 20 which is guided with a guide element 21, in this case not recognizable, in a groove 19 of the clamp 18 in a circular path. In the operating position, when the blade 13 cuts the web of material, the plunger 14 is in this upper position, the flange 20 with the guide element 21 meeting at the upper stop of the groove 19. The plunger 14 is held in this position. position with the flange 20 by means of spring elements not shown. The spring elements are adjustable in configuration so that the locking forces can be varied for this position. According to the state of the art, a dull blade 13 caused a material jam, as a result of which a breakage of the plunger 14 often occurred.
De acuerdo con la invención, en caso de un atasco de material, el pisador 14 puede pivotar con la brida 20 a una posición de desviación inferior (figura 5), de tal modo que el dispositivo de corte transversal 10 no sea dañado. A este respecto, la fuerza de los elementos de resorte es superada y la brida 20 con el pisador 14 se desplaza a lo largo de la ranura 19 dispuesta circularmente a la posición de desviación inferior.According to the invention, in the event of a material jam, the plunger 14 can pivot with the flange 20 to a lower deflection position (Figure 5), so that the cross-cutting device 10 is not damaged. In this regard, the force of the spring elements is overcome and the flange 20 with the plunger 14 moves along the circularly arranged groove 19 to the lower deflection position.
Después de retirarse el material atascado entre cuchilla rotativa 13 y pisador 14, la brida 20 con el pisador 14 puede pivotar por medio de mango 23 y palanca 22 manualmente a la posición de funcionamiento (figura 4). El mango 23 y la palanca 22 no están montados de manera fija, sino que pueden encajarse en la posición de desviación en un orificio de la brida. La ranura 19 está configurada de tal modo que el pisador 14 puede pivotar con la brida 20 aproximadamente 90° fuera del encaje con la cuchilla 13, lo cual se realiza en esta vista en el sentido de las agujas del reloj en dirección del material.After removal of the material jammed between the rotating blade 13 and the plunger 14, the flange 20 with the plunger 14 can be pivoted by means of the handle 23 and lever 22 manually to the operating position (figure 4). The handle 23 and the lever 22 is not fixedly mounted, but can be engaged in the offset position in a hole in the flange. The slot 19 is configured such that the plunger 14 can pivot with the flange 20 approximately 90 ° out of engagement with the blade 13, which is done in this view in a clockwise direction in the direction of the material.
Preferentemente, la posición del pisador 14 o de la brida 20 se puede supervisar por medio de un sensor, de tal modo que, si pivotan estos dos componentes, se transmita una señal al control máquina bobinadora 1. Esta puede activar una señal de aviso para el usuario o parar automáticamente el funcionamiento de la máquina bobinadora. En lugar de un retorno manual desde la posición de desviación a la posición de funcionamiento por medio de mango 23 y palanca 22, la brida 20 también puede ser retornada automáticamente con el pisador 14. Para ello, está previsto que la cuchilla 13 permanezca quieta y el bastidor 16 se desplace a lo largo de la guía 12 de nuevo a la posición de espera en la brida 11 fuera de la banda de material.Preferably, the position of the plunger 14 or of the flange 20 can be monitored by means of a sensor, such that, if these two components pivot, a signal is transmitted to the winding machine control 1. This can activate a warning signal to the user or automatically stop the operation of the winding machine. Instead of a manual return from the deflection position to the operating position by means of the handle 23 and lever 22, the flange 20 can also be automatically returned with the hold-down 14. For this, it is provided that the blade 13 remains stationary and the frame 16 moves along the guide 12 back to the waiting position on the flange 11 outside the web of material.
La figura 6 muestra una representación en sección del dispositivo de corte transversal, en el que cuchilla 13 está dispuesta paralelamente a la sujeción 18. En esta representación, puede observarse el elemento guía 21, que guía la brida 20 a lo largo de la ranura. Por encima de la brida 20, puede observarse el pisador 14, que forma con la cuchilla 13 un pequeño intersticio vertical en esta representación. En la brida 20 está configurado a modo de ejemplo un elemento de enclavamiento 24 que puede cooperar como clavija cargada por resorte con punta cónica o redondeada con un rebaje 25. El elemento de enclavamiento 24 puede ser presionado fuera del rebaje 25 según una fuerza de ruptura predefinida por la fuerza del resorte, de tal modo que la brida 20 con el pisador 14 puede pivotar a lo largo de la ranura 19 a la posición de desviación. Por supuesto, son posibles dispositivos de enclavamiento alternativos en el marco de la invención.Figure 6 shows a sectional representation of the transverse cutting device, in which the blade 13 is arranged parallel to the clamp 18. In this representation, the guide element 21 can be seen, which guides the flange 20 along the groove. Above the flange 20, the plunger 14 can be seen, which forms a small vertical gap with the blade 13 in this representation. An example of a locking element 24 is configured on the flange 20, which can cooperate as a spring-loaded pin with a conical or rounded tip with a recess 25. The locking element 24 can be pressed out of the recess 25 according to a breaking force predefined by spring force, such that flange 20 with plunger 14 can pivot along slot 19 to the deflection position. Of course, alternative locking devices are possible within the framework of the invention.
