HOJA DE SUSTITUCIÓN (REGLA 26) En la campo industrial de la fabricación de calzado, especialmente en el caso de la fabricación de botas, se conoce como operación de "rayado" del calzado al hecho de aplicar una cinta protectora a la costura realizada a lo largo de la caña de la bota. De este modo se evita que dicha costura entre en contacto con la pierna del usuario y pueda provocar molestias a este último.SUBSTITUTE SHEET (RULE 26) In the industrial field of the manufacture of footwear, especially in the case of the manufacture of boots, it is known as the operation of "scratching" of the footwear when applying a protective tape to the seam made along the boot shaft . This prevents the seam from coming into contact with the user's leg and can cause discomfort to the latter.
En la actualidad, la operación de rayado se lleva a cabo con la ayuda de máquinas que presentan un brazo al que se acopla la pieza de la bota, siendo dicho braao susceptible de desplazarse según la dirección, longitudinal de éste una vez que el usuario acciona un pedal. El mantenimiento de la pieza de la bota sobre el brazo, se realiza en virtud de la acción ejercida por el propio operario, con sus manos, tensando la pieza y acompañando a esta última en su desplazamiento sobre el brazo. La operación exige una cierta pericia por parte del usuario, puesto que cualquier ligero movimiento de éste, provoca un descentrado de la pieza y una aplicación incorrecta de la cinta de rayar. Además, es una operación laboriosa que mantiene al operario en tensión y que provoca en éste una fatiga excesiva al final de la jornada.At present, the scratching operation is carried out with the help of machines that have an arm to which the boot part is attached, said braao being able to move according to the longitudinal direction of the boot once the user activates a pedal The maintenance of the piece of the boot on the arm, is done by virtue of the action exerted by the operator himself, with his hands, tightening the piece and accompanying the latter in its movement on the arm. The operation requires a certain skill on the part of the user, since any slight movement of the user, causes a decentration of the piece and an incorrect application of the scratch tape. In addition, it is a laborious operation that keeps the operator in tension and that causes excessive fatigue at the end of the day.

HOJA DE SUSTITUCIÓN (REGLA 26) La máquina de la Figura 1 consta de un bastidor 1 mediante el que se proporciona el soporte estructural a los diversos componentes, complementado inferiormente por una bancada que, por motivos de simplicidad de la representación, no aparece en los dibujos. Un brazo desplazable, perfectamente guiado en su movimiento de vaivén, señalado con la referencia 2, muestra una porción delantera 2a que se ha configurado superiormente de modo que presenta, en general, un perfil similar al de una bota, con el fin de proporcionar un buen soporte a la pieza de calzado a rayar, mientras que una porción 2b de dicho brazo desplazable, incorpora una cremallera en la que engranan medios adecuados asociados un grupo moto-reductor 3 situado en la parte trasera de la máquina.SUBSTITUTE SHEET (RULE 26) The machine of Figure 1 consists of a frame 1 whereby the structural support is provided to the various components, inferiorly complemented by a bench that, for reasons of simplicity of representation, does not appear in the drawings. A movable arm, perfectly guided in its reciprocating movement, indicated with reference 2, shows a front portion 2a that has been configured superiorly so that it generally presents a profile similar to that of a boot, in order to provide a good support for the piece of footwear to be scratched, while a portion 2b of said movable arm incorporates a zipper in which suitable means associated with a motor-reducer group 3 located at the rear of the machine.
Sujetos al bastidor 1, se encuentran medios de aplicación de la cinta de rayar, constituidos por sendos cilindros neumáticos 4, 5 que se encargar de mover, en dirección vertical descendente-ascendente , roldanas 6, 7 respectivas, presionadoras contra la superficie de la bota 8 (representada a puntos) a cuya costura se está aplicando la cinta de rayar. Un botón de emergencia 9 se encuentra situado en la parte frontal de la estructura del bastidor, en una posición fácilmente accesible para el operario, con el fin de que pueda ser accionado en caso de necesidad.Subject to the frame 1, there are means for applying the scratch tape, constituted by two pneumatic cylinders 4, 5 which are responsible for moving, in the downward-ascending vertical direction, respective rollers 6, 7, pressed against the boot surface 8 (represented by dots) to whose seam the scratch tape is being applied. An emergency button 9 is located in the front part of the frame structure, in a position easily accessible to the operator, so that it can be operated if necessary.
En relación con el brazo 2 desplazable y situado por la parte inferior de éste, se ha previsto la disposición de un elemento retenedor, señalado con la referencia numérica 10, obtenido en forma laminar con sección transversal en media caña, que por la parte delantera puede ser movido verticálmente en dirección descendente-ascendente con la ayuda de un pequeño cilindro 11 sujeto al extremo frontal del propio brazo 2 desplazable, mientras que en relación con la- narte trasera-puede ser desplazado y.ejrt.. calmente en-jatayorIn relation to the movable arm 2 and located on the lower part of the latter, the provision of a retaining element, indicated by the numerical reference 10, obtained in a laminar form with a cross-section in half-round, which can be provided by the front part can be provided be moved vertically in a downward-ascending direction with the help of a small cylinder 11 attached to the front end of the movable arm 2 itself, while in relation to the rear lane-it can be moved and eg ... warmly in-jatayor

Este elemento 10 retenedor, cuando es accionado por los cilindros 11, 12 citados, desciende y ejerce un empuje sobre el borde de la bota 8 opuesto al de rayado, inmovilizando la bota en esa posición y haciendo por tanto innecesaria la participación del operario mientras se realiza la operación de rayar.SUBSTITUTE SHEET (RULE 26) measured, by virtue of the action of one or two pneumatic cylinders 12 that move together with said arm 2. This retaining element 10, when actuated by the aforementioned cylinders 11, 12, descends and exerts a thrust on the edge of the boot 8 opposite to the scratch, immobilizing the boot in that position and thus making unnecessary the participation of the operator while performing the scratch operation.
Por último, desde la bancada de la máquina se eleva verticalmente un poste 13 hasta una altura determinada, el cual incorpora medios de emisión-recepción de luz (preferentemente luz infrarro a), en una posición tal que se enfrenta a una superficie lisa brillante de la porción 2a del brazo desplazable, y la cual no es apreciable en la Figura por estar situada en el lado opuesto de dicha porción 2a. En concreto, esta superficie brillante consiste en una banda longitudinal, de anchura predeterminada, que afecta a la casi totalidad de la longitud de la porción 2a del brazo deslizante, de tal manera que, al incidir la luz emitida por los medios emisores incorporadas en el poste 13, dicha luz se refleja en la banda brillante y es captada por los medios receptores, hasta que se alcanza el comienzo de la caña de una bota 8 colocada en dicha porción 2a de brazo deslizante, en cuyo momento deja de reflejarse la luz, o se refleja en una cantidad inferior a un umbral determinado, con lo cual, los medios electrónicos de control asociados a la máquina (no representados), entienden que existe una bota 8 colocada en la porción 2a del brazo 2 , y se inicia el ciclo de rayado .Finally, from the machine bed a pole 13 rises vertically to a certain height, which incorporates light emission-reception means (preferably infrared light), in a position such that it faces a bright smooth surface of the movable arm portion 2a, and which is not noticeable in the Figure because it is located on the opposite side of said portion 2a. Specifically, this glossy surface consists of a longitudinal band, of predetermined width, which affects almost the entire length of the portion 2a of the sliding arm, such that, when the light emitted by the emitting means incorporated in the post 13, said light is reflected in the bright band and is captured by the receiving means, until the beginning of the cane of a boot 8 placed in said sliding arm portion 2a is reached, at which time the light ceases to be reflected, or is reflected in an amount less than a certain threshold, whereby the electronic control means associated with the machine (not shown), understand that there is a boot 8 placed in the portion 2a of the arm 2, and the cycle begins of striped.

La Figura 3 ilustra una vista en alzado lateral de la máquina, tomada desde el lado opuesto al de la Figura 2. En esta Figura aparecen ya los elementos citados anteriormente y que no eran apreciables en Ja anterior Figura, tal como la banda brillante 15 prevista para la reflexión de la luz infrarroja, mientras que el elemento retenedor 10 aparece también en posición plegada, es decir, no operativa. Sin embargo, en esta Figura 3 se aprecia también otra característica importante de la invención, que consiste, en particular, en la provisión de los medios de corte automático de la cinta de rayar. En el caso de la realización preferida que se está describiendo, tales medios de corte están constituidos por una cuchilla 14 ya mencionada, asociada a un mecanismo de paralelogramo articulado, obtenido en torno a una biela 16 descendente, susceptible de oscilar con respecto a la roldana 7 delantera cuando es accionada al final del recorrido del brazo 2 desplazable, contra la acción de un resorte 18. Esta situación ha sido representada a mayor tamaño en las Figuras 4 y 5 de los dibujos, las cuales muestran, respectivamente, una situación en la que la cuchilla 14 está en posición retraída, enfrentada a la cinta 17, y una posición en la que dicha cuchilla 14 ha sido accionada y ha realizado el corte de la cinta 17 tras oscilar, junto con su soporte 19, en torno al eje de giro de la propia roldana 7 delantera. En la última Figura, la cinta 17 aparece ya partida, -y-_li-s4a- a^a—iniciar un nuevo ciclo.Figure 3 illustrates a side elevational view of the machine, taken from the side opposite to that of Figure 2. In this Figure the elements mentioned above appear and were not noticeable in the previous Figure, such as the intended bright band 15 for the reflection of the infrared light, while the retaining element 10 also appears in the folded position, that is, not operative. However, in this Figure 3 another important feature of the invention is also appreciated, which consists, in particular, in the provision of the automatic cutting means of the scratch tape. In the case of the preferred embodiment that is being described, such cutting means are constituted by an aforementioned blade 14, associated with an articulated parallelogram mechanism, obtained around a descending connecting rod 16, capable of oscillating with respect to the sheave 7 forward when it is actuated at the end of the travel of the movable arm 2, against the action of a spring 18. This situation has been shown in a larger size in Figures 4 and 5 of the drawings, which show, respectively, a situation in the that the blade 14 is in a retracted position, facing the tape 17, and a position in which said blade 14 has been actuated and has made the cutting of the tape 17 after oscillating, together with its support 19, around the axis of turn of the front roller itself 7. In the last Figure, the tape 17 appears already split, -and-_li-s4a- to ^ a — start a new cycle.
HOJA DE SUSTITUCIÓN (REGLA 26) Como se comprenderá, la incorporación de la banda 15 de naturaleza brillante proporciona a la máquina una importante característica añadida, puesto que la capacita para detectar, por si misma el tamaño de la bota 8 colocada en la porción 2a del brazo 2 desplazable. En efecto, dependiendo de la longitud de la bota 8, la reflexión de la luz dejará de producirse en un momento distinto del movimiento de desplazamiento, siendo este instante el determinante del inicio de la aplicación automática de la cinta 17 a la costura de la bota 8.SUBSTITUTE SHEET (RULE 26) As will be understood, the incorporation of the band 15 of a bright nature provides the machine with an important added feature, since it enables it to detect, by itself, the size of the boot 8 placed in the portion 2a of the movable arm 2. Indeed, depending on the length of the boot 8, the reflection of the light will cease to occur at a different time from the movement of movement, this instant being the determinant of the start of the automatic application of the tape 17 to the seam of the boot 8.
Se debe aclarar que la forma de realización del mecanismo de corte es únicamente ilustrativa, puesto que existen otras muchas alternativas para la realización del mismo. Así, de acuerdo con la invención, una segunda realización preferida de tal mecanismo de corte consiste simplemente en la sustitución del citado paralelogramo por un cilindro de accionamiento neumático (no representado), comandado apropiadamente para hacer girar, en el momento correspondiente, el soporte 19 en el que se ha montado la cuchilla 14, y hacer así que se produzca el corte de la cinta 17.It should be clarified that the embodiment of the cutting mechanism is only illustrative, since there are many other alternatives for its realization. Thus, according to the invention, a second preferred embodiment of such a cutting mechanism simply consists in replacing said parallelogram with a pneumatically operated cylinder (not shown), appropriately commanded to rotate, at the corresponding moment, the support 19 on which the blade 14 has been mounted, and so that the cutting of the tape 17 occurs.
Además, se debe tener presente que los movimientos de los distintos órganos estarán regulados por sensores, finales de carrera u otros medios que no han sido representados por ser convencionales y conocidos en el estado de la técnica. Las informaciones obtenidas a partir de tales medios, transformadas en señales eléctricas, son enviadas a un centro electrónico de control (no representado ni descrito por ser convencional), donde son analizadas y tratadas para la toraa de decisiones con relación a la función a desarrollar por el órgano que corresponda.In addition, it should be borne in mind that the movements of the different organs will be regulated by sensors, limit switches or other means that have not been represented as being conventional and known in the state of the art. The information obtained from such means, transformed into electrical signals, is sent to an electronic control center (not represented or described as being conventional), where they are analyzed and processed for decision-making regarding the function to be developed by the body that corresponds.
