Description

Máquina de corte personalizado superficial de piezas de masa de pan o similar  Custom surface cutting machine for bread dough pieces or similar
MEMORIA DESCRIPTIVA OBJETO DE LA INVENCIÓN  DESCRIPTIVE MEMORY OBJECT OF THE INVENTION
La presente solicitud tiene por objeto el registro de una máquina de corte personalizado superficial de piezas de masa de pan o similar. The purpose of the present application is the registration of a surface custom cutting machine for pieces of bread dough or the like.
Más concretamente, la invención propone el desarrollo de una máquina de corte personalizado superficial de piezas de masa de pan o similar que permite realizar un corte personalizado y repetitivo de un diseño de corte con formas complejas, sobre la pieza de masa de pan en un proceso productivo continuo, siendo el corte realizado por medio de agua presurizada. More specifically, the invention proposes the development of a customized surface cutting machine for pieces of bread dough or the like that allows a custom and repetitive cut of a cutting design with complex shapes, on the piece of bread dough in a process continuous production, being the cut made by means of pressurized water.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Es conocida la realización de cortes distribuidos de forma paralela entre sí sobre la superficie de una pieza (o barra) hecha a partir de una masa de pan, cuyos cortes se realizan previamente al horneado de la masa de pan. Los cortes tienen una finalidad decorativa que permite personalizar la pieza de pan así como también funcional al permitir que el pan no tenga defectos de forma por efecto de la cocción y mejore la cocción de la masa. It is known to make cuts distributed parallel to each other on the surface of a piece (or bar) made from a bread dough, whose cuts are made prior to baking the bread dough. The cuts have a decorative purpose that allows you to customize the piece of bread as well as functional by allowing the bread to have no defects in shape due to the effect of cooking and improve the baking of the dough.
Estos cortes se realizan de forma manual sobre la superficie de la masa de pan por un operario mediante la ayuda de una herramienta de corte de filo. Sin embargo, este proceso presenta una serie de inconvenientes, entre los cuales están el hecho de que no se puede garantizar una repetibilidad de la forma ni profundidad de los cortes realizados durante un proceso productivo. Además, dado que el corte se realiza de forma manual, existe un riesgo de que alguna pieza de masa de pan no tenga los cortes o incluso el mismo número de cortes por un descuido del operario encargado de realizar los cortes. These cuts are made manually on the surface of the bread dough by an operator using a cutting edge tool. However, this process has a series of drawbacks, among which are the fact that repeatability of the shape or depth of the cuts made during a production process cannot be guaranteed. In addition, since the cutting is done manually, there is a risk that some piece of bread dough does not have the cuts or even the same number of cuts due to an oversight of the operator in charge of making the cuts.
Es conocido en el estado de la técnica la patente española ES 465371 que describe una instalación para la fabricación de pan que comprende unos medios de escarificación automática de pan basados en el uso de una serie de cuchillas de corte soportadas en una estructura de soporte y situadas sobre una cinta transportadora. Si bien dicha instalación permite realizar cierta repetitividad en los cortes realizados, no permite en ningún caso personalizar el tipo de corte a realizar, por lo que se limita su versatibilidad. Además, en el caso de modificar el corte a realizar sobre el pan, implicaría el desmontaje de la estructura donde están las cuchillas para su sustitución, hecho que comportaría un tiempo considerable no operativo así como la disposición de un número diferente de estructuras o disposición de cuchillas de corte. Otro inconveniente, es el hecho de que las cuchillas de corte deben ser sustituidas debido a su desgaste. Además, el solicitante no tiene conocimiento en la actualidad de una invención que disponga de todas las características que se describen en esta memoria. It is known in the state of the art the Spanish patent ES 465371 which describes an installation for the manufacture of bread comprising means of automatic scarification of bread based on the use of a series of cutting blades supported on a support structure and located on a conveyor belt. Although this installation allows to perform some repetitiveness in the cuts made, it does not allow in any case to customize the type of cut to be made, so its versatility is limited. In addition, in the case of modifying the cut to be made on the bread, it would imply the disassembly of the structure where the blades are for replacement, a fact that would entail a considerable non-operational time as well as the provision of a different number of structures or arrangement of cutting blades Another drawback is the fact that the cutting blades must be replaced due to their wear. In addition, the applicant is not currently aware of an invention that has all the features described herein.
DESCRIPCIÓN DE LA INVENCIÓN La presente invención se ha desarrollado con el fin de proporcionar una máquina de corte que se configura como una novedad dentro del campo de aplicación y resuelve los inconvenientes anteriormente mencionados, aportando, además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación.

Mencionar que el ángulo de giro puede ser ilimitado, es decir, el cabezal puede realizar una o más vueltas completas respecto a su propio eje. DESCRIPTION OF THE INVENTION The present invention has been developed in order to provide a cutting machine that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from The description that follows. It is therefore an object of the present invention to provide a customized surface cutting machine for pieces of bread dough or the like to make cuts with complicated shapes, whose shapes have linear and / or curved strokes, comprising a worktable on the that the pieces of bread dough are movable, a cutting equipment that acts on the surface of the pieces of bread dough, and a control unit linked to the cutting equipment, which is characterized by the fact that the unit of control is programmable and can be connected to an interface for the entry of instructions related to a custom design of the cut to be made on the piece of bread dough, the cutting equipment comprising a motorized rotary head capable of moving in any direction of any the three coordinate axes (x, y, z) and perform a rotating movement with respect to a coordinate axis (z) orthogonal to the coordinate axis (x).

Now, when it comes to cutting equipment, it includes a robotic rotating head, indicated in general with reference (6), which is capable of turning unlimitedly on its own axis (a) (that is, it can rotate more in a turn), it is slidably supported on a gantry structure (7) arranged transversely to the direction of advance of the pieces of bread dough (2), as represented by the arrows (f) in the Figures 1 and 2. The fact that the rotating head (6) can rotate more than 360 degrees makes it possible to make a cut, for example, with a serpentine shape, as shown in Figure 7. With particular reference to the equipment of cutting comprises means for cutting by pressurized fluid, which include at least one pressurized fluid outlet nozzle (8) which is located at the bottom (9) of the rotary head (6), the outlet nozzle (8) being connected to a source of fluid supply through with exions, such as flexible ducts, which allow 360-degree rotation or more than one turn of the rotating head, and an input socket present at the bottom of the rotating head (6).
Preferentemente, el fluido utilizado es agua, si bien podría emplearse cualquier otro fluido adecuado bajo presión, como por ejemplo, aceite, agua mezclada con otros compuesto, etc. El fluido presurizado que sale por la boquilla (8) puede ser regulado mediante un regulador de presión convencional (no representado), por lo que el fluido puede estar bajo una presión comprendida entre 5 y 25 bares. De este modo, puede adaptarse la presión de corte al tipo de masa de pan a manipular con la máquina. El cabezal rotativo (6) está montado en una guía (10) constituida por un perfil metálico alargado, que está unida transversalmente de forma deslizable en la estructura de pórtico (7), por lo que el cabezal rotativo (6) puede girar sobre su propio eje central, desplazarse longitudinalmente y transversalmente con respecto a la dirección de avance de las piezas de masa de pan. La guía (10) está acoplada de forma deslizable a la estructura de pórtico (7) por medio de un carro deslizante (20). Preferably, the fluid used is water, although any other suitable fluid could be used under pressure, such as oil, water mixed with other compounds, etc. The pressurized fluid exiting the nozzle (8) can be regulated by a conventional pressure regulator (not shown), whereby the fluid can be under a pressure between 5 and 25 bar. In this way, the cutting pressure can be adapted to the type of bread dough to be handled with the machine. The rotary head (6) is mounted on a guide (10) constituted by an elongated metal profile, which is slidably connected transversely in the gantry structure (7), whereby the rotary head (6) can rotate on its own central axis, move longitudinally and transversely with respect to the direction of advance of the pieces of bread dough. The guide (10) is slidably coupled to the gantry structure (7) by means of a sliding carriage (20).
En lo que respecta al equipo de visión artificial comprende al menos una cámara de captación de imágenes (11) (por ejemplo, una cámara de imágenes en 3D) y un generador de haz de láser (12), representados de forma esquematizada en la figura 2, estando ambos conectados con la unidad de control mediante conexiones eléctricas. Tanto la cámara 3D como el generador de láser (12) son dispositivos comercialmente disponibles en el mercado por lo que no se va entrar en mayor detalle en su descripción. With regard to artificial vision equipment, it comprises at least one image capture camera (11) (for example, a 3D image camera) and a laser beam generator (12), schematically represented in the figure 2, both being connected to the control unit through electrical connections. Both the 3D camera and the laser generator (12) are commercially available devices on the market, so it is not going to go into more detail in its description.
En una realización alternativa representada en las figuras 5 y 6, los medios de corte incluyen una pluralidad de boquillas de salida (8') que están situadas en la parte inferior el cabezal giratorio. Esta pluralidad de boquillas de salida (8') está soportada en una disposición en serie sobre un perfil alargado (13) que está provisto de unos medios de acoplamiento (19) que sobresalen superiormente hacia arriba, los cuales permiten acoplarse al cabezal giratorio. Cada una de las boquillas de salida (8') está soportada en el perfil alargado (13) por medio de una pletina (14) fijada a la boquilla de salida (8') y vinculada al perfil alargado (13) por un par de elementos de tornillería (15). In an alternative embodiment represented in Figures 5 and 6, the cutting means include a plurality of outlet nozzles (8 ') that are located at the bottom of the rotating head. This plurality of outlet nozzles (8 ') is supported in a series arrangement on an elongated profile (13) which is provided with coupling means (19) that protrude upwardly, which allow it to be coupled to the rotating head. Each of the outlet nozzles (8 ') is supported on the elongated profile (13) by means of a plate (14) fixed to the outlet nozzle (8') and linked to the elongated profile (13) by a pair of hardware elements (15).
Para facilitar manualmente la manipulación del perfil alargado, se proporcionan unos medios de agarre que consisten en un asidero (16) unido a una pletina (17), que permiten a un usuario manipular con facilidad la zona donde se encuentran las boquillas de salida, por ejemplo, para su montaje o desmontaje en tareas de mantenimiento y/o sustitución. To manually facilitate the manipulation of the elongated profile, grip means are provided consisting of a handle (16) attached to a plate (17), which allow a user to easily manipulate the area where the outlet nozzles are located, by for example, for assembly or disassembly in maintenance and / or replacement tasks.
Como se ha representado en la figura 6, las boquillas de salida (8') están interconectadas y comunicadas de forma fluida entre sí, habiendo una sola toma de entrada (18) dispuesta de forma centrada. En la figura 8 se ha representado una masa de pan para panecillos que presenta en su parte superior un corte (21) en forma de "M", a diferencia del clásico corte lineal que suele realizarse previamente a la cocción de la masa de pan. En una realización no representada de la invención, la mesa de trabajo puede incluir unos medios de tope escamoteable que actúan durante el funcionamiento de la máquina para detener el desplazamiento de las bandejas con la masa de pan, estando estos medios de tope gestionados por la unidad de control, permitiendo así trabajar de forma sincronizada con el equipo de corte. En un ejemplo de realización, los medios de tope pueden comprender una pletina asociada a un sistema neumático o hidráulico que actúa para elevar y bajar la pletina, de modo que cuando la pletina está en una posición elevada hace tope con una bandeja de piezas de masa de pan mientras que en una posición bajada, permite el paso de la bandeja en la dirección de avance. Los detalles, las formas, las dimensiones y demás elementos accesorios, empleados en la fabricación de la máquina de la invención podrán ser convenientemente sustituidos por otros que no se aparten del ámbito definido por las reivindicaciones que se incluyen a continuación. As shown in Figure 6, the outlet nozzles (8 ') are interconnected and fluidly communicated with each other, with only one inlet socket (18) arranged centrally. Figure 8 shows a bread dough for rolls that has an "M" shaped cut (21) in its upper part, unlike the classic linear cut that is usually made prior to the baking of the bread dough. In an unrepresented embodiment of the invention, the worktable can include retractable stop means that act during the operation of the machine to stop the displacement of the trays with the bread dough, these stop means being managed by the unit control, thus allowing to work synchronously with the cutting equipment. In an exemplary embodiment, the stop means may comprise a plate associated with a pneumatic or hydraulic system that acts to raise and lower the plate, so that when the plate is in an elevated position it stops with a tray of dough pieces of bread while in a lowered position, allows the tray to pass in the forward direction. The details, shapes, dimensions and other accessory elements used in the manufacture of the machine of the invention may be conveniently substituted by others that do not depart from the scope defined by the claims included below.
