Description

Cilindro para impresión.Cylinder for printing.

Object of the invention

La presente invención, tal y como se expresa en el enunciado de esta memoria descriptiva, se refiere a un cilindro para impresión cuya finalidad es proporcionar un cilindro que pueda imprimir fácilmente y de manera correcta sobre soportes de superficies irregulares, tales como azulejos o madera, y que además facilite la correspondiente colocación y retirada de la camisa que incluye el motivo a imprimir y que se dispone sobre el correspondiente cilindro. Para ello, el cilindro de la invención dispone de una superficie acolchada o mullida sobre un núcleo rígido que facilita la impresión y que cuenta con unas salidas de aire que permiten efectuar las operaciones de encamisado y desencamisado con gran facilidad.The present invention, as expressed in the statement of this specification refers to a cylinder for printing whose purpose is to provide a cylinder that can print easily and correctly on media irregular surfaces, such as tiles or wood, and that in addition facilitate the corresponding placement and removal of the shirt that It includes the reason to be printed and that is available on the corresponding cylinder. For this, the cylinder of the invention It has a padded or fluffy surface on a core rigid that facilitates printing and that has outputs of air that allow you to perform jacketing operations and unchained with great ease.

Background of the invention

Son conocidos los cilindros de impresión que se emplean para imprimir en flexografía o huecograbado, presentando estos cilindros o rodillos una estructura rígida en los que se incorpora una camisa también rígida. Estos cilindros conocidos presentan inconvenientes de que son poco adaptables a superficies irregulares tales como los azulejos o la madera, de manera que la impresión en estas superficies resulta muy dificultosa con los referidos cilindros convencionales rígidos.The printing cylinders that are known are used to print in flexography or gravure, presenting these cylinders or rollers a rigid structure in which incorporates a shirt also rigid. These known cylinders they have disadvantages that they are not very adaptable to surfaces irregular such as tiles or wood, so that the printing on these surfaces is very difficult with referred to conventional rigid cylinders.

Description of the invention

Para lograr los objetivos y evitar los inconvenientes indicados en anteriores apartados, la invención consiste en un cilindro para impresión en cuya superficie se acopla una camisa que incorpora el motivo a imprimir.To achieve the objectives and avoid drawbacks indicated in previous sections, the invention It consists of a cylinder for printing whose surface is coupled a shirt that incorporates the reason to print.

Novedosamente, según la invención, el cilindro de la misma cuenta con un núcleo rígido sobre cuya superficie se dispone un colchón de espuma de poro cerrado que está atravesado por unos orificios de salida de aire que permiten la generación de un cojín de aire entre el cilindro y la camisa al objeto de facilitar las operaciones de encamisado y desencamisado.Novelly, according to the invention, the cylinder of it has a rigid core on whose surface it It has a closed pore foam mattress that is crossed through some air outlet holes that allow the generation of an air cushion between the cylinder and the sleeve in order to facilitate the operations of jacketed and shirtless.

Con la configuración descrita se proporciona una superficie de impresión relativamente mullida que facilita la impresión sobre superficies tales como madera o azulejos. Además, con las salidas de aire descritas se facilita en gran medida la colocación y la retirada de la correspondiente camisa flexible. Así, al introducir la camisa en el cilindro se aplica aire comprimido que saldrá por los orificios correspondientes determinando un cojín de aire entre el cilindro y la camisa que facilita la colocación de dicha camisa, tras lo cual se suprime el referido aire comprimido y la camisa queda dispuesta para realizar la correspondiente impresión. Una vez finalizada la impresión, y en caso de tener que cambiar la camisa, se vuelve a aplicar el aire comprimido de manera que se genera un cojín de aire que facilita la retirada de la camisa.With the described configuration, a relatively soft printing surface that facilitates printing on surfaces such as wood or tiles. Further, with the air outlets described, the placement and removal of the corresponding flexible shirt. Thus, when the jacket is introduced into the cylinder, air is applied tablet that will exit through the corresponding holes determining an air cushion between the cylinder and the jacket that facilitates the placement of said shirt, after which the referred compressed air and the jacket is arranged to perform The corresponding impression. Once the printing is finished, and in if you have to change the shirt, the air is reapplied compressed so that an air cushion is generated that facilitates the shirt removal

A continuación, para facilitar una mejor comprensión de esta memoria descriptiva y formando parte integrante de la misma se acompañan unas figuras en las que con carácter ilustrativo y no limitativo se ha representado el objeto de la invención.Then, to facilitate a better understanding of this specification and being part members of it are accompanied by some figures in which with illustrative and non-limiting nature the object has been represented of the invention.

Brief description of the figures

Figura 2.- Representa una vista análoga a la de la anterior figura 1 pero estando incorporándose en el referido cilindro una camisa dotada del correspondiente motivo de impresión.Figure 2.- Represents a view similar to that of the previous figure 1 but being incorporated in the referred cylinder a shirt with the corresponding motive of Print.

Description of an embodiment of the invention

Seguidamente se realiza una descripción de un ejemplo de la invención haciendo referencia a la numeración adoptada en las figuras.Following is a description of a example of the invention with reference to numbering Adopted in the figures.

Así, el cilindro para impresión de este ejemplo de realización cuenta con un núcleo rígido 1 esencialmente cilíndrico y cuya superficie dispone de un rehundido o bajorrelieve en el que se acopla un colchón de espuma de poro cerrado 2 tal y como se representa en la figura 1.Thus, the printing cylinder of this example of embodiment has a rigid core 1 essentially cylindrical and whose surface has a recess or bas-relief in which a closed pore foam mattress 2 is attached and such as depicted in figure 1.

Este colchón 2 queda atravesado por unas salidas de aire 3 que permiten la generación de un cojín de aire entre el cilindro y una camisa 4 que se incorporará sobre el mismo y que dispondrá del correspondiente motivo a imprimir.This mattress 2 is crossed by exits of air 3 that allow the generation of an air cushion between the cylinder and a jacket 4 that will be incorporated thereon and that You will have the corresponding reason to print.

Así, al incorporar o retirar la camisa 4 del cilindro, tal y como muestra la figura 2, se aplicará al cilindro aire comprimido para que por las salidas 3 salga aire a presión y determine un cojín de aire entre el cilindro y la camisa 4 que facilitará la retirada o la colocación de dicha camisa 4.Thus, by incorporating or removing shirt 4 from cylinder, as shown in figure 2, will be applied to the cylinder compressed air so that pressurized air exits 3 and determine an air cushion between the cylinder and the jacket 4 that facilitate the removal or placement of said shirt 4.

Es importante destacar que la espuma del colchón 2 sea de poro cerrado, puesto que si fuese de poro abierto no podría establecerse eficientemente el referido cojín de aire entre la camisa y el cilindro.It is important to note that the foam of the mattress 2 is closed pore, since if it were open pore no the aforementioned air cushion could be efficiently established between The shirt and the cylinder.

Claims

1. Cylinder for printing, on the surface of which a shirt (4) that incorporates the motif to be printed is attached; characterized in that it has a rigid core (1) on whose surface there is a closed pore foam mattress (2) that is crossed by air outlet holes (3) that allow the generation of an air cushion between the cylinder and the shirt in order to facilitate the operations of jacketed and shirtless.
