OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un dispositivo para suministro e inserción de hilo con chip en la costura de una prenda, aportando, a la función a que se destina, ventajas y características, que se describen en detalle más adelante, que suponen una destacable novedad en el estado actual de la técnica.The invention, as expressed in the wording of the present specification, refers to a device for supplying and inserting yarn with a chip in the seam of a garment, providing, to the function for which it is intended, advantages and characteristics, which are described in detail below, which represent a remarkable novelty in the current state of the art.

El objeto de la presente invención recae en un dispositivo eléctrico/electrónico cuya finalidad es configurarse como medio para proporcionar el suministro de hilos con chip, particularmente hilos con chip RFID (Radio Frequency Identification o identificación por radiofrecuencia) y antena NFC (Near Field Communication Comunicación de campo cercano) de los que se incorporan en las prendas de confección como medida de seguridad antirrobo, el cual dispositivo, además, al mismo tiempo permite la introducción de dicho hilo con chip en la costura de una prenda durante la confección de la misma a través de unos medios de impulsión de aire comprimido.The object of the present invention lies in an electrical / electronic device whose purpose is to be configured as a means to provide the supply of wires with a chip, particularly wires with an RFID ( Radio Frequency Identification or radio frequency identification) chip and an NFC (Near Field Communication Communication) antenna. near field) of those that are incorporated into garments as an anti-theft security measure, which device, in addition, at the same time allows the introduction of said thread with chip in the seam of a garment during the manufacture of the same to through compressed air drive means.

CAMPO DE APLICACIÓN DE LA INVENCIÓNFIELD OF APPLICATION OF THE INVENTION

El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de aparatos y dispositivos eléctrico-electrónicos, abarcando concretamente el campo de los concernientes a los hilos con chip, a la vez que el ámbito de la industria textil.The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of electrical-electronic appliances and devices, specifically encompassing the field of those concerning chip wires, as well as the field of industry. textile.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Son conocidos en el mercado los hilos que llevan embebido unos chips RFID con unas antenas a lo largo de los mismos. Una porción de dicho hilo con un chip y una antena se introduce en algún lugar de una prenda de ropa (dobladillo, cuello, manga...), en sustitución de las etiquetas RFID tradicionales, que están vistas y pueden ser fácilmente extraíbles. El hecho de que sea un hilo, supone una ventaja frente a las etiquetas, ya que dificulta que el usuario lo encuentre y lo pueda extraer. El chip RFID se puede utilizar para incorporar información aunque principalmente tiene una función de alarma para evitar hurtos en los comercios.Threads that have embedded RFID chips with antennas along them are known in the market. A portion of said thread with a chip and an antenna is inserted somewhere in a garment (hem, neck, sleeve ...), replacing traditional RFID tags, which are visible and can be easily removable. The fact that it is a thread is an advantage over labels, since it makes it difficult for the user to find and extract it. The RFID chip can be used to incorporate information, although it mainly has an alarm function to prevent shoplifting.

El hilo, además del chip, lleva unas marcas visuales que indican por donde se debe cortar para que la porción del hilo a incorporar en la prenda contenga un chip y la antena correspondiente.The thread, in addition to the chip, has visual markings that indicate where it should be cut so that the portion of the thread to be incorporated into the garment contains a chip and the corresponding antenna.

El hilo se puede suministrar de dos maneras. Una manera es ya cortado en tramos que contienen un chip y una antena. En este modo la confeccionista debe coger un hilo de uno en uno del recipiente y colocarlo correctamente en la pieza de ropa donde lo debe fijar.The thread can be supplied in two ways. One way is already cut into sections that contain a chip and an antenna. In this mode, the confectioner must take a thread one at a time from the container and place it correctly on the piece of clothing where it must be fixed.

El hilo también se puede entregar en forma de bobina. En este caso la costurera deberá cortar el hilo correctamente, para que contenga solo un chip y una antena, y colocarlo en la pieza de ropa.The thread can also be delivered in coil form. In this case, the seamstress will have to cut the thread correctly, so that it contains only a chip and an antenna, and place it on the piece of clothing.

El problema es que el hilo es difícil de colocar, puesto que necesita ser colocado de manera recta o prácticamente recta para que la antena cumpla con su función, ya que cuando el hilo se dobla el chip no funciona. Además, el suministro del hilo a la costurera es difícil, al ser un hilo que se dobla fácilmente y difícil de manipular.The problem is that the wire is difficult to place, since it needs to be placed in a straight or practically straight way for the antenna to fulfill its function, since when the wire is bent the chip does not work. In addition, the supply of the thread to the seamstress is difficult, as it is a thread that is easily bends and difficult to manipulate.

Para solventar esta problemática, el propio solicitante ha desarrollado un dispositivo, convenientemente protegido en solicitud de patente, diseñado para hacer que el suministro de dicho hilo sea el óptimo para facilitar su recogida a la costurera y poder colocarlo adecuadamente en la prenda, para lo cual, esencialmente, comprende una estructura de soporte; unos medios de desplazamiento del hilo proveniente de una bobina; unos medios de guiado que ponen el hilo recto; unos medios detectores que comprueban la posición del chip RFID en el hilo; unos medios de comprobación del funcionamiento del chip RFID; unos medios de corte que cortan el hilo en un segmento que incluye un chip; unos medios que expulsan parcialmente el segmento de hilo (4) con chip funcional para ser recogido; y unos medios de control informatizado de todos los componentes eléctricos y electrónicos que incluyen dichos medios.To solve this problem, the applicant himself has developed a device, conveniently protected in the patent application, designed to make the supply of said thread optimal to facilitate its collection by the seamstress and to be able to place it properly in the garment, for which It essentially comprises a support structure; means for moving the thread coming from a spool; a guide means that puts the wire straight; detector means that check the position of the RFID chip on the wire; means for checking the operation of the RFID chip; a cutting means that cuts the wire in a segment that includes a chip; means that partially eject the yarn segment (4) with a functional chip to be picked up; and means of computerized control of all the electrical and electronic components that include said means.

Dicho dispositivo, sin embargo, si bien cumple satisfactoriamente con la función a que se destina, presenta ciertos aspectos susceptibles de ser mejorados. En particular los referidos a la limitación de la funcionalidad del mismo, ya que únicamente está diseñado para suministrar los hilos, cortados y comprobados, para que la costurera los recoja en la posición idónea, pero debiendo, a partir de ahí, ser ella la que agarra e introduce el hilo en alguna de las costuras de la prenda durante la confección de la misma, operación que sería deseable poder efectuarse también de manera automática y controlada, ya que este tipo de hilo es muy delicado de manipular y su introducción en la costura sin que se arrugue o que de mal puesto supone una especial destreza para poder realizarla de manera rápida y correcta, lo cual por tanto puede llevar a una ralentización de la producción que repercute en los costes de fabricación. Said device, however, while satisfactorily fulfilling its intended function, has certain aspects that could be improved. In particular, those referring to the limitation of its functionality, since it is only designed to supply the threads, cut and checked, so that the seamstress picks them up in the ideal position, but from there, she must be the one who grabs and inserts the thread into any of the garment's seams during its making, an operation that would also be desirable to be able to be carried out in an automatic and controlled manner, since this type of thread is very delicate to handle and its introduction into the seam Without wrinkling or poorly placed, it is a special skill to be able to do it quickly and correctly, which can therefore lead to a slowdown in production that affects manufacturing costs.

El objetivo de la presente invención es, pues, el desarrollo de un dispositivo del tipo antedicho en una versión más avanzada que, además de proporcionar los medios para suministrar de manera idónea los hilos, es decir, cortados con un chip, comprobados y en la posición correcta, también proporcione los medios para insertar dichos hilos directamente en la costura de la prenda en el momento de efectuarla al confeccionar la prenda y pudiendo hacerlo solo cuando se precise, ya que lógicamente, solo se incluye en alguna de las costuras, no en todas.The objective of the present invention is, therefore, the development of a device of the aforementioned type in a more advanced version that, in addition to providing the means to supply the wires in an ideal way, that is, cut with a chip, tested and in the correct position, also provide the means to insert said threads directly into the seam of the garment at the time of making it when making the garment and being able to do so only when required, since logically, it is only included in some of the seams, not in all.

Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, si bien como se ha dicho se conoce un dispositivo de aplicación similar para el suministro de hilos con chip, al menos por parte del solicitante, se desconoce la existencia de ningún otro dispositivo para suministro e inserción de hilo con chip en la costura de una prenda ni ninguna otra invención que presente características técnicas, estructurales y constitutivas iguales o semejantes a las que presenta el que aquí se reivindica.On the other hand, and as a reference to the current state of the art, it should be noted that, although, as has been said, a similar application device for supplying wires with a chip is known, at least by the applicant, the existence of of any other device for supplying and inserting chip yarn into the seam of a garment or any other invention that presents technical, structural and constitutive characteristics equal or similar to those presented herein.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El dispositivo para suministro e inserción de hilo con chip en la costura de una prenda que la invención propone se configura pues como una destacable novedad dentro de su campo de aplicación, ya que a tenor de su implementación, se alcanzan satisfactoriamente los objetivos anteriormente señalados como idóneos, estando los detalles caracterizadores que lo hacen posible y que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción.The device for supplying and inserting yarn with a chip in the seam of a garment that the invention proposes is therefore configured as a remarkable novelty within its field of application, since according to its implementation, the objectives previously indicated as suitable, being the characterizing details that make it possible and that distinguish it conveniently collected in the final claims that accompany the present description.

Concretamente, lo que la invención propone, como se ha indicado anteriormente, es un dispositivo constituido para suministrar hilos con chip RFID embebido, de los que se incorporan en prendas de confección, normalmente como medio de alarma, y además para insertarlo directamente en la costura de la prenda durante la confección de la misma con una máquina de coser o incluso una vez efectuada, estando dicho hilo ya cortado para que contenga un chip, colocado en la posición adecuada y habiendo sido comprobado su correcto funcionamiento o descartado en caso de no ser apto, produciéndose dicha inserción del hilo en la costura gracias a unos medios de impulsión de aire comprimido.Specifically, what the invention proposes, as indicated above, is a device constituted to supply threads with embedded RFID chip, the kind that are incorporated into garments, usually as a means of alarm, and also to be inserted directly into the seam of the garment during the manufacture of the garment with a sewing machine or even once carried out, being said Thread already cut to contain a chip, placed in the proper position and having been checked for correct operation or discarded if it is not suitable, the thread being inserted into the seam by means of compressed air drive means.

Para todo ello, el dispositivo se incorpora convenientemente instalado junto a la máquina de coser y comprende integrados en su estructura un conjunto de medios eléctricos y electrónicos que, controlados mediante un sistema informático implementado en un PLC, hacen posible dicha entrega partiendo de una bobina donde el hilo esta en continuo así como su inserción sin tener que manipularlo gracias un grupo compresor que lo impulsa a través de un conjunto de tubos asociados a dichos medios.For all this, the device is incorporated conveniently installed next to the sewing machine and includes integrated into its structure a set of electrical and electronic means that, controlled by a computer system implemented in a PLC, make such delivery possible starting from a coil where the thread is continuous as well as its insertion without having to manipulate it thanks to a compressor group that drives it through a set of tubes associated with said means.

Así, en una primera fase, el hilo accede desde la bobina a una primera zona del dispositivo donde un primer tensor lo hace pasar por un rodete que ayuda a guiar el hilo frente a unos medios de detección visual, preferentemente un sensor de contraste, que comprueba la posición de las marcas del hilo y del chip.Thus, in a first phase, the thread accesses from the spool to a first area of the device where a first tensioner makes it pass through an impeller that helps to guide the thread in front of visual detection means, preferably a contrast sensor, which Check the position of the thread and chip marks.

Tras ello, un segundo tensor encara el hilo hacia un rodillo motorizado que queda protegido dentro de un receptáculo de aluminio, el cual actúa como medio para desplazar el hilo ya que lo empuja hacia los medios de corte situados a continuación, los cuales, constituidos por una cizalla, cortan el hilo en un segmento que contiene un chip.After that, a second tensioner faces the wire towards a motorized roller that is protected within an aluminum receptacle, which acts as a means to move the wire since it pushes it towards the cutting means located below, which, constituted by a shear, they cut the thread into a segment containing a chip.

A continuación, el dispositivo incorpora los medios de detección del correcto funcionamiento del chip, consistentes en la existencia de un sensor de detección y comprobación de chips RFid, frente al cual el hilo pasa insertado en un tubo, que llamaremos conductor. A dicho tubo conductor se le introduce aire comprimido que desplaza el hilo a través del tubo conductor hasta el selector. Durante el trayecto del hilo, el selector permite la salida del aire comprimido a través de otro conducto. Cuando el hilo llega al selector, el selector, si el chip del hilo funciona correctamente, permite pasar el hacia una guía tubular, preferentemente metálica. En caso contrario, el selector, si el chip es defectuoso, lo rechaza cerrando el paso del tubo de aire para que no pase a la guía, y permitiendo la salida de este del dispositivo a través de un conducto a tal efecto.Next, the device incorporates the means for detecting the correct operation of the chip, consisting of the existence of a RFid chip detection and verification sensor, in front of which the thread passes inserted in a tube, which we will call conductor. Compressed air is introduced to said conductive tube, which moves the wire through the conductive tube to the selector. During the path of the wire, the selector allows the compressed air to escape through another duct. When the wire reaches the selector, the selector, if the wire chip works correctly, allows it to pass towards a tubular guide, preferably metallic. Otherwise, the selector, if the chip is defective, rejects it by closing the passage of the air tube so that it does not pass into the guide, and allowing it to exit the device through a conduit for this purpose.

Conviene señalar que, preferentemente, el tubo (8) actúa como salida de aire comprimido del tubo conductor (7) para que este salga durante la primera fase de inyección de aire, ya que interesa que el aire que existe previo al hilo (3) salga del sistema, puesto que en caso contrario, el hilo se arrugaría dentro de dicho tubo y no avanzaría. Una vez dicho aire previo al hilo (3) ya ha salido y dicho tubo (8) se cierra.It should be noted that, preferably, the tube (8) acts as an outlet for compressed air from the conductive tube (7) so that it comes out during the first phase of air injection, since it is important that the air that exists prior to the thread (3) exit the system, since otherwise, the thread would wrinkle inside said tube and it would not advance. Once said air prior to the thread (3) has already come out and said tube (8) is closed.

Opcionalmente, el sensor de detección y comprobación del chip RFID sirve también como grabador, para configurarlo con información, por ejemplo de talla, modelo, u otra, pudiendo ser modificada por el usuario comerciante o distribuidor de la prenda mediante un dispositivo dotado de los medios de comunicación correspondientes.Optionally, the sensor for detecting and checking the RFID chip also serves as a recorder, to configure it with information, for example size, model, or other, which can be modified by the merchant user or distributor of the garment by means of a device equipped with the means corresponding communication channels.

Por su parte, dicha guía tubular consiste en un fino conducto, preferentemente metálico y preferentemente de aluminio, que presenta una configuración curva y de longitud suficiente para permitir la introducción de todo el largo de un hilo con chip en el interior de una costura en el momento de efectuarla en una prenda con la máquina a que se acopla el dispositivo. For its part, said tubular guide consists of a thin conduit, preferably metallic and preferably aluminum, which has a curved configuration and of sufficient length to allow the introduction of the entire length of a chip wire inside a seam in the moment of carrying it out on a garment with the machine to which the device is coupled.

Para ello, además, esta guía se encuentra anclada a la máquina acoplada en un adaptador universal, que permite su colocación junto a la aguja de la máquina sin interferir en el funcionamiento normal de la misma.For this, in addition, this guide is anchored to the machine attached to a universal adapter, which allows it to be placed next to the machine needle without interfering with its normal operation.

Y, ventajosamente, dicho adaptador está incorporado en una sujeción basculante que permite ser fácilmente apartado de la zona de manipulación de la prenda cuando no sea necesario introducir ningún hilo con chip.And, advantageously, said adapter is incorporated in a tilting holder that allows it to be easily removed from the garment's handling area when it is not necessary to introduce any chip yarn.

Asimismo, preferentemente, el extremo distal de la guía tubular metálica que proporciona la introducción del hilo en la costura impulsado por el aire comprimido, tiene una punta punzante que permite introducir dicho hilo dentro de costuras ya cerradas previamente.Likewise, preferably, the distal end of the metallic tubular guide that provides the introduction of the thread in the seam driven by the compressed air, has a pointed tip that allows the insertion of said thread into previously closed seams.

En todo caso, cabe mencionar que la descrita disposición de los diferentes medios de funcionamiento del dispositivo puede sufrir variaciones en cuanto al orden de posición de cada uno de ellos, siempre y cuando siga siendo efectiva su función.In any case, it should be mentioned that the described arrangement of the different operating means of the device may undergo variations in terms of the order of position of each one of them, as long as their function continues to be effective.

Por último, conviene señalar que la máquina en que se instala el dispositivo de la invención, preferentemente, es una máquina de las que efectúa costuras de tipo overlock o sobrehilado, que cómo es sabido es un tipo de costura que se realiza sobre el borde de una o dos piezas de tela para definir el borde pero también para encapsularlo, de manera que el hilo se introducirá en dicho encapsulado, si bien ello no supone una limitación.Finally, it should be noted that the machine on which the device of the invention is installed is preferably a machine that sews overlock or overcast type, which as is known is a type of seam that is performed on the edge of one or two pieces of fabric to define the edge but also to encapsulate it, so that the thread will be introduced into said encapsulation, although this is not a limitation.

El descrito dispositivo para suministro e inserción de hilo con chip en la costura de una prenda consiste, pues, en una estructura innovadora de características desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The described device for supplying and inserting yarn with a chip in the seam of a garment therefore consists of an innovative structure with characteristics unknown until now for the purpose for which it is intended, reasons that, together with its practical usefulness, provide it with a sufficient basis to obtain the privilege of exclusivity that is requested.
