Description
Dispositivo y procedimiento extractor de recortes y máquina cortadora de material laminar flexible que incorpora el dispositivo.Device and cut-out procedure and flexible sheet cutting machine incorporating the device.
La presente invención se refiere a un dispositivo y a un procedimiento para la extracción de recortes en forma de tira o de cinta continua destinado a una máquina cortadora de material laminar flexible procedente de bobina, con detección de dichos recortes.The present invention relates to a device and to a procedure for the extraction of cuts in the form of continuous strip or strip intended for a cutting machine flexible sheet material from coil, with detection of said cuts.
La invención se refiere también a una máquina cortadora de material laminar flexible procedente de bobina que incorpora el mencionado dispositivo para la extracción de recortes en forma de cinta continua.The invention also relates to a machine flexible sheet material cutter from coil that incorporates the aforementioned device for the extraction of cuts in the form of continuous tape.
Son conocidas en el estado de la técnica unas máquinas cortadoras-bobinadas que disponen unos medios para efectuar uno o más cortes longitudinales en un material laminar flexible, desenrollado a partir de una única bobina, y unos medios para volver a enrollar las dos o más bandas resultantes en unas correspondientes bobinas de menor anchura. También son conocidas unas máquinas cortadoras para efectuar consecutivos cortes transversales en un material laminar flexible desenrollado a partir de una bobina para producir hojas sueltas. Generalmente, tanto las máquinas de corte longitudinal como transversal realizan un saneamiento de los bordes laterales del material procedente de la bobina, lo que genera un residuo o recorte en forma de cinta continua que debe ser extraído de la máquina, por ejemplo, hacia un contenedor recolector.Some are known in the state of the art winding-cutting machines that have some means for making one or more longitudinal cuts in a material flexible sheet, unwound from a single coil, and about means for rewinding the two or more bands resulting in corresponding coils of smaller width. They are also known cutting machines to make consecutive cross sections in a flexible sheet material unwound to from a coil to produce single sheets. Usually, both longitudinal and transverse cutting machines perform a sanitation of the lateral edges of the material coming from the coil, which generates a residue or cut in the form of tape continues to be removed from the machine, for example, towards a collecting container
Es también conocido utilizar, para la citada extracción del recorte en forma de cinta, un sistema de aspiración conectado a un conducto por el interior del cual es evacuado el recorte. Uno de tales sistemas de aspiración conocidos comprende un conducto de aspiración para cada recorte, que generalmente son dos, correspondientes a los márgenes laterales del material procedente de la bobina, con un extremo inferior abierto, por el que entra el correspondiente recorte, y un extremo superior comunicado con un conducto colector, el cual a su vez está conectado a un ventilador que produce una corriente de aspiración en el interior del colector y, por efecto Venturi, también en el interior de los conductos de aspiración, provocando con ello la circulación de los recortes a través de sus respectivos conductos de aspiración y del colector hacia el exterior, donde los recortes son depositados en el mencionado contenedor recolector, de donde son posteriormente eliminados o reciclados. Cada recorte circula por su correspondiente conducto de una manera holgada, es decir, sin que el material en forma de cinta vaya guiado de una manera precisa, sino efectuando movimientos aleatorios dentro del espacio confinado por las paredes del conducto.It is also known to use, for the aforementioned extraction of the tape-shaped cutout, a suction system connected to a conduit through which the cutout is evacuated. One such known aspiration system comprises an aspiration conduit for each cut, which are generally two, corresponding to the lateral margins of the material coming from the coil, with an open bottom end, through which the corresponding cut enters, and an end upper communicated with a collecting duct, which in turn is connected to a fan that produces a suction current inside the collector and, by Venturi effect, also inside the suction ducts, thereby causing the circulation of the cuts through their respective suction ducts and the collector to the outside, where the cuts are deposited in the said collection container, from where they are subsequently disposed of or recycled. Each cut circulates through its corresponding conduit in a loose manner, that is, without the tape-shaped material being guided in a precise manner, but by making random movements within the space confined by the walls of the conduit.
Los dispositivos de extracción de recortes del tipo descrito tienen el inconveniente de que cuando el recorte se rompe y deja de entrar en el tubo de aspiración, o cuando el recorte se atasca dentro del tubo de aspiración, el recorte generado y no extraído se puede enrollar en cualquiera de las bobinas adyacentes, produciendo un malfuncionamiento en la máquina. Esto supone generalmente cortes en la producción con unas consiguientes pérdidas económicas y de tiempo.The clip extraction devices of the type described have the disadvantage that when the clipping is breaks and stops entering the suction tube, or when the clipping gets stuck inside the suction tube, clipping generated and not extracted can be rolled in any of the adjacent coils, causing a malfunction in the machine. This generally involves cuts in production with some consequent economic and time losses.
Es un objetivo de la presente invención solucionar los inconvenientes citados anteriormente mediante la aportación de un dispositivo de extracción fiable que permita reducir la posibilidad de que en la máquina se produzcan fallos.It is an objective of the present invention solve the aforementioned problems by contribution of a reliable extraction device that allows reduce the possibility that the machine will occur failures.
Según un primer aspecto, la invención se refiere a un dispositivo extractor de recortes, para una máquina manipuladora de material laminar flexible continuo, del tipo que comprende un sistema de aspiración conectado a al menos un conducto para arrastrar por aspiración a través de dicho conducto un recorte en forma de cinta continua procedente de dicha máquina. El dispositivo está caracterizado porque comprende además unos medios de detección, asociados a dicho conducto, adaptados para detectar un movimiento aleatorio de dicho recorte en el interior del conducto y unos medios de procesamiento, conectados con dichos medios de detección, adaptados para emitir una orden de control para dicha máquina en caso de no detectarse dicho movimiento del recorte en el interior del conducto.According to a first aspect, the invention relates to to a clipper device, for a machine continuous flexible sheet material handler, of the type that comprises a suction system connected to at least one duct to suction drag through said conduit a cutout in the form of continuous tape from said machine. He device is characterized in that it also comprises means of detection, associated with said conduit, adapted to detect a random movement of said cut inside the duct and processing means, connected with said means of detection, adapted to issue a control order for said machine in case of not detecting said movement of the cut in the duct inside.
Los citados medios de detección comprenden al menos un conjunto detector adaptado para efectuar una captación de una emisión en al menos dos direcciones transversales a través de dicho conducto y emitir al menos una señal representativa de dicha captación o de una interrupción de dicha captación, mientras que dichos medios de procesamiento están adaptados para efectuar sucesivas lecturas de dicha señal, que es al menos una, comparar cada nueva lectura con una o más lecturas precedentes, y emitir dicha orden de control en función del resultado de dicha comparación.The said detection means comprise the less a detector set adapted to perform a capture of an emission in at least two transverse directions through said conduit and emit at least one representative signal from said uptake or interruption of said uptake while said processing means are adapted to effect successive readings of said signal, which is at least one, compare each new reading with one or more previous readings, and issue said control order based on the result of said comparison.
De este modo se consigue un dispositivo para la extracción de recortes que detecta tanto la rotura del recorte como el atasco del recorte en el interior del conducto a partir no sólo de la presencia sino también del movimiento aleatorio del recorte a su paso por los medios de detección. De hecho, los medios de detección del dispositivo de la invención no distinguen entre la no presencia del recorte y una presencia inmóvil del recorte, sin embargo, en cualquiera de los dos casos, el dispositivo puede considerar un funcionamiento anómalo del extractor y provocar el paro de la máquina antes de que el recorte se enrolle en alguna de las bobinas cercanas y provoque un malfuncionamiento de la misma, evitándose tiempos muertos en la producción.In this way a device for the clip extraction that detects both the breakage of the trim and the clipping jam inside the duct from not only of the presence but also of the random movement of the cutout as it passes through the detection means. In fact, the means of detection of the device of the invention do not distinguish between the no presence of the cutout and a still presence of the cutout, without However, in either case, the device can consider abnormal operation of the extractor and cause stop the machine before the clipping is rolled in any of the nearby coils and cause a malfunction of it, avoiding dead times in production.
Según una característica ventajosa de la
invención, los medios de detección de recortes son ópticos, y
comprenden al menos dos pares de emisor y receptor dirigidos en
distintas direcciones transversales a través del conducto. Aunque
los pares de emisor y receptor podían ser del tipo de reflexión,
preferiblemente el emisor de cada par de emisor y receptor está
enfrentado a su correspondiente receptor y el dispositivo y se
incluyen al menos cuatro de dichos pares de emisor y receptor
orientados en distintas direcciones transversales diametrales y
cruzadas a través del conducto de manera que en todo momento al
menos un par de emisor y receptor detecta la presencia del recorte.
Debido al movimiento aleatorio del recorte en el interior del
conducto, el número y situación de los pares de emisor y receptor
que detectan o no detectan la presencia del recorte cambian en cada
lectura, y por medio de la comparación de las sucesivas lecturas,
los medios de procesamiento determinan si existe movimiento, y en
caso contrario generan una señal de control para, por ejemplo,
provocar el paro de la máquina y evitar los problemas citados
anterior-
mente.According to an advantageous feature of the invention, the clip detection means are optical, and comprise at least two emitter and receiver pairs directed in different transverse directions through the conduit. Although the emitter and receiver pairs could be of the reflection type, preferably the emitter of each emitter and receiver pair is facing its corresponding receiver and the device and at least four of said emitter and receiver pairs oriented in different directions are included. diametral and cross-sectional through the duct so that at least one transmitter and receiver pair at all times detects the presence of the cutout. Due to the random movement of the cut inside the duct, the number and location of the emitter and receiver pairs that detect or do not detect the presence of the cut change at each reading, and by comparing the successive readings, the means of processing determine if there is movement, and otherwise generate a control signal to, for example, cause the machine to stop and avoid the problems mentioned above-
mind.
Cada par de emisor y receptor detecta la presencia del recorte cuando dicho recorte se interpone entre el haz generado por el emisor hacia el receptor. En el caso de que el receptor reciba el haz generado por el emisor, dicho receptor envía una señal de no presencia del recorte a los medios de procesamiento de la señal. Así, por ejemplo, el par de emisor y receptor puede comprender diodos emisores de luz (LEDs), generando el LED emisor un haz de luz infrarroja hacia el receptor que detecta el paso del recorte. Los medios de procesamiento reciben las señales de los diferentes receptores y las procesan para detectar el cambio de luz producido por la intersección del recorte en el haz de luz.Each transmitter and receiver pair detects the presence of the clipping when said clipping is interposed between the beam generated by the sender towards the receiver. In the event that the receiver receives the beam generated by the transmitter, said receiver sends a signal of no presence of the cut to the processing means Of the signal. Thus, for example, the sender and receiver pair can comprise light emitting diodes (LEDs), generating the emitting LED a infrared beam of light towards the receiver that detects the passage of cutout. The processing means receive the signals from the different receivers and process them to detect the change of light produced by the intersection of the clipping in the light beam.
En una realización, el conducto comprende al menos una parte transparente, alrededor de la cual se dispone el par de emisor y receptor. Gracias a esta transparencia del conducto, los medios de detección de recortes se pueden colocar cómodamente en un alojamiento anular fuera del conducto, protegidos de golpes o suciedad y fácilmente accesibles para operaciones de mantenimiento.In one embodiment, the conduit comprises the less a transparent part, around which the transmitter and receiver pair. Thanks to this transparency of duct, clip detection means can be placed comfortably in an annular housing outside the duct, protected from bumps or dirt and easily accessible for operations maintenance.
Según otro aspecto, la presente invención se refiere a un procedimiento para la extracción de recortes, para una máquina manipuladora de material laminar flexible continuo, del tipo que comprende los pasos de generar, mediante un sistema de aspiración, una corriente de aspiración en el interior de al menos un conducto, y arrastrar por aspiración a través de dicho conducto un recorte en forma de cinta continua procedente de dicha máquina. El procedimiento caracterizado porque comprende además los pasos de: detectar mediante unos medios de detección asociados a dicho conducto un movimiento aleatorio de dicho recorte en el interior del conducto; y emitir, mediante unos medios de procesamiento conectados con dichos medios de detección, una orden de control para la máquina en caso de no detectarse dicho movimiento del recorte en el interior del conducto.According to another aspect, the present invention is refers to a procedure for the extraction of clippings, for a continuous flexible sheet material handling machine, of the type which includes the steps of generating, through a system of suction, a suction current inside at least a conduit, and suction drag through said conduit a cut in the form of continuous tape from said machine. The procedure characterized in that it also includes the steps of: detecting by means of detection means associated with said conduit a random movement of said cutout inside of the duct; and issue, through processing means connected with said detection means, a control order for the machine in case of not detecting said movement of the cut inside the duct.
Aún según otro aspecto, la invención se refiere a una máquina manipuladora de material laminar flexible continuo, que comprende un dispositivo para la extracción de recortes de acuerdo con el primer aspecto de la invención.Still according to another aspect, the invention relates to a continuous flexible sheet material handling machine, which comprises a device for the extraction of cuts according with the first aspect of the invention.
En una realización, el procedimiento comprende también una etapa (D) de parada de la máquina, en el caso no detectarse el recorte en la etapa (C).In one embodiment, the method comprises also a step (D) of stopping the machine, in case no the clipping detected in step (C).
También se puede dar el caso de que sólo se genere un aviso a la persona encargada de la máquina, y no se provoque el paro de la misma.It can also be the case that only generate a notice to the person in charge of the machine, and do not know cause it to stop.
Una máquina para la manipulación de rollos de material flexible, que comprende medios de corte de dicho material y un dispositivo para la extracción de recortes como el descrito.A machine for handling rolls of flexible material, comprising cutting means of said material and a device for extracting cuts like the described
Para una mejor comprensión de cuanto se ha expuesto se acompañan unos dibujos en los que, esquemáticamente y sólo a título de ejemplo no limitativo, se representa un caso práctico de realización.For a better understanding of how much has been exposed are accompanied by drawings in which, schematically and only as a non-limiting example, a case is represented practical implementation.
En dichos dibujos:In these drawings:
la figura 1 muestra un diagrama esquemático del dispositivo para la extracción de recortes de acuerdo con la invención, montado en una máquina; yFigure 1 shows a schematic diagram of the device for extraction of cuts according to the invention, mounted on a machine; Y
la figura 2 muestra una vista en perspectiva seccionada de los medios de detección de recortes del dispositivo para la extracción de recortes de la figura 1, con indicación en línea de puntos de la parte de recorte a detectar, para mejor claridad del dibujo.Figure 2 shows a perspective view sectioning of the device clip detection means for the extraction of clippings of figure 1, with indication in dotted line of the clipping part to be detected, for better clarity of the drawing
En la figura 1 se representa una vista parcial de una máquina 1 destinada, por ejemplo, a la confección, manipulación y acabado de todo tipo de pequeños rollos de papel, plástico y complejos, que comprende un dispositivo para la extracción de recortes de acuerdo con la invención.Figure 1 shows a partial view of a machine 1 intended, for example, for clothing, handling and finishing all kinds of small rolls of paper, plastic and complexes, comprising a device for the extraction of clippings according to the invention.
Como se puede ver, dicha máquina 1 recibe un material laminar 2, por ejemplo papel o plástico, en forma de banda B, procedente de una bobina, no representada, que corta longitudinalmente mediante unos elementos de corte adecuados 4, obteniendo una pluralidad de bandas de papel B1, B2, B3, B4, B5, B6 que serán posteriormente rebobinadas, y realizando un saneamiento de los laterales del material laminar 2, a partir del que se obtienen en los márgenes unos residuos o recortes 5, 6. Como recorte se entiende cualquier tira o fragmento de material en forma de banda estrecha o cinta, en este caso papel o plástico, que ha sido cortado y que debe ser separado del resto.As you can see, said machine 1 receives a sheet material 2, for example paper or plastic, in the form of a web B, coming from a coil, not shown, that cuts longitudinally by means of suitable cutting elements 4, obtaining a plurality of paper bands B1, B2, B3, B4, B5, B6 which will be subsequently rewound, and performing a sanitation of the sides of the sheet material 2, from which they are obtained in the margins some residues or cuts 5, 6. As a cut is understand any strip or fragment of band-shaped material narrow or tape, in this case paper or plastic, which has been cut and that must be separated from the rest.
Posteriormente, los recortes 5, 6 se introducen
en unos correspondientes conductos 7, 7a donde son aspirados por
efecto Venturi generado por Ej. por un ventilador o turbina 8, y
dirigidos hacia un conducto 13 colector, de evacuación que
desemboca a través de una boca de vertido 10 en un depósito
recolector 15. Es importante destacar que los conductos 7, 7a
pueden ser considerados como cualquier tipo de medio por el que se
transportan los recortes 5, 6, tenga una configuración cerrada o
abierta. El tipo de conducto utilizado dependerá en cada caso del
material del recorte y del dispositivo de extracción
implementado.Subsequently, the cuts 5, 6 are introduced into corresponding ducts 7, 7a where they are aspirated by Venturi effect generated by, for example, a fan or turbine 8, and directed towards a collecting duct 13, evacuation that flows through a mouth of discharge 10 in a collection tank 15. It is important to note that the ducts 7, 7a can be considered as any type of means by which the cuts 5, 6 are transported, have a closed or open configuration. The type of conduit used will depend in each case on the material of the cutout and the extraction device
implemented
La aspiración de los recortes 5, 6 obtenida por medio del ventilador 8 provoca que dichos recortes circulen por el interior de los conductos 7, 7a hasta llegar a unos medios de detección de recortes 9, 9a, asociados a dichos conductos 7, 7a, que detectan un movimiento aleatorio de dichos recortes 5, 6 en el interior del correspondiente conducto 7, 7a.The aspiration of the cuts 5, 6 obtained by fan medium 8 causes said cuts to circulate through the inside the ducts 7, 7a until reaching some means of detection of cuts 9, 9a, associated with said ducts 7, 7a, that detect a random movement of said cuts 5, 6 in the inside the corresponding duct 7, 7a.
En el momento en que dichos medios de detección de recortes 9, 9a no detectan el movimiento de al menos uno de los recortes 5, 6, consideran la rotura o parada por atasco del/de los mismo/s y envían una señal a un ordenador central (no mostrado) de control de la máquina 1, para dar un aviso o provocar el paro de la misma. En el caso de que no se produzca la rotura o atasco de los recortes, éstos siguen circulando por los respectivos conductos 7, 7a hasta depositarse finalmente, a través del conducto 13 colector, de evacuación, en un recolector 10.At the moment said detection means of cuts 9, 9a do not detect the movement of at least one of the cuts 5, 6, consider the breakage or stoppage due to the traffic jam same / s and send a signal to a central computer (not shown) of machine control 1, to give a warning or cause the same. In the event that there is no breakage or jamming of the cuts, these continue to circulate through the respective ducts 7, 7a until finally deposited, through the conduit 13 collector, of evacuation, in a collector 10.
Como se puede ver en la figura 2, los medios o conjunto de detección de recortes comprenden una carcasa 11 asociada al conducto 7, y una pluralidad de pares de emisor y receptor E1-R1, E2-R2, E3-R3, E4-R4, E5-R5, montados en el Ejemplo representado, sobre una placa de circuito impreso 14, orientados en distintas direcciones transversales a través del conducto 7, 7a y dispuestos alrededor de un tubo transparente 12, en el interior de la carcasa 11.As you can see in Figure 2, the media or clip detection assembly comprise a housing 11 associated with conduit 7, and a plurality of emitter pairs and E1-R1, E2-R2 receiver, E3-R3, E4-R4, E5-R5, mounted in the example shown, on a circuit board printed 14, oriented in different transverse directions to through the duct 7, 7a and arranged around a tube transparent 12, inside the housing 11.
De acuerdo con un posible ejemplo de realización,
cada uno de dicha pluralidad de pares de emisor y receptor
E1-R1, E2-R2, E3-R3,
E4-R4, E5-R5, comprende unos LEDs
(diodos emisores de luz) que crean unos haces de luz infrarroja y
que dado su número y disposición espacial son capaces de detectar
el movimiento del recorte 5 ó 6 por el interior del correspondiente
conducto 7, 7a sea cual sea su orientación. Cuando circula el
recorte 5 ó 6 a través de los medios de detección de recortes 9,
9a, el movimiento de dicho recorte 5, 6 provoca que los haces de luz
infrarroja generados por los emisores no lleguen a los
receptores.According to a possible embodiment, each of said plurality of transmitter and receiver pairs E1-R1, E2-R2, E3-R3, E4-R4, E5-R5, comprises LEDs (light emitting diodes) that they create infrared light beams and that given their number and spatial arrangement they are able to detect the movement of the cutout 5 or 6 inside the corresponding conduit 7, 7a whatever their orientation. When the cutout 5 or 6 circulates through the cutout detection means 9, 9a, the movement of said cutout 5, 6 causes the infrared light beams generated by the emitters not to reach the
receivers
Unos medios de procesamiento (no mostrados) dispuestos también en el interior de los medios de detección de recortes 9, o en un punto remoto, asociado, reciben las señales de los receptores y las procesan para detectar los cambios de luz producidos por la intersección o no de los recortes 5, 6 en los haces de luz infrarroja.Processing means (not shown) also arranged inside the detection means of clippings 9, or at a remote, associated point, receive signals from the receivers and process them to detect the light changes produced by the intersection or not of the cuts 5, 6 in the infrared light beams
En el caso de que se produzca la rotura de un recorte 5, 6 dicho recorte deja de circular por el interior de los medios de detección de recortes 11, y, por lo tanto, no cortará los haces de luz infrarroja generados por los emisores, los cuales alcanzarán a los correspondientes receptores. Por su parte, en caso de inmovilización del recorte por Ej. por un atasco se producirán también a lo largo de un determinado tiempo unas lecturas sucesivas, iguales, del detector de cada uno de los pares de emisor-detector.In the event of the breakage of a cutout 5, 6 said cutout stops circulating inside the clip detection means 11, and therefore will not cut the infrared light beams generated by emitters, which they will reach the corresponding receivers. On the other hand, in case of immobilization of the cut for eg by a traffic jam will occur also over a certain time some readings successive, equal, of the detector of each of the pairs of emitter-detector
Así pues, en cualquiera de las situaciones de anomalía consideradas, cuando dos o más lecturas sucesivas de los pares de emisor y receptor E1-R1, E2-R2, E3-R3, E4-R4, E5-R5, resulten iguales, dichos medios de procesamiento envían una señal al ordenador central de control de la máquina 1 para dar un aviso o provocar el paro de la misma, evitando, por ejemplo, que el recorte 5, 6 roto o atascado se enrolle en cualquiera de las bobinas o rodillos y ejes próximos y provoque un malfuncionamiento en el paso del papel 2 y del consiguiente rebobinado, que derivan en cortes en la producción.So, in any of the situations of anomaly considered, when two or more successive readings of the E1-R1 transmitter and receiver pairs, E2-R2, E3-R3, E4-R4, E5-R5, equal, said means of processing send a signal to the central control computer of machine 1 to give a warning or cause it to stop, preventing, for example, that the cut 5, 6 broken or stuck is wind in any of the coils or rollers and nearby shafts and cause a malfunction in the passage of paper 2 and the consequently rewind, which result in cuts in production.
Conforme al procedimiento de esta invención, dichos medios de procesamiento están adaptados para efectuar sucesivas lecturas de dichas señales, comparando cada nueva lectura con una o más lecturas precedentes, y emitiendo dicha orden de control en función del resultado de dicha comparación.In accordance with the process of this invention, said processing means are adapted to effect successive readings of these signals, comparing each new reading with one or more previous readings, and issuing said order of control based on the result of said comparison.
A pesar de que se ha descrito y representado una realización concreta de la presente invención, es evidente que el experto en la materia podrá introducir variantes y modificaciones, o sustituir los detalles por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas.Although it has been described and represented a concrete embodiment of the present invention, it is evident that the subject matter expert may introduce variants and modifications, or replace the details with technically equivalent ones, without depart from the scope of protection defined by the attached claims.
Por ejemplo, el número de pares de emisor y receptor puede ser cualquiera, siempre que sea suficiente para detectar el movimiento del recorte al atravesar los medios de detección de recortes sea cual sea la orientación espacial de dicho recorte acintado; su número dependerá en buena medida del tipo de recorte y del tamaño del conducto.For example, the number of emitter pairs and receiver can be anyone, as long as it is enough to detect the movement of the cut by crossing the means of clip detection whatever the spatial orientation of said tapered cutout; their number will depend largely on the type of cut and duct size.
Además, los pares de emisor y receptor pueden comprender cualquier otro elemento diferente a los LEDs, siendo preferibles elementos ópticos.In addition, the sender and receiver pairs can understand any element other than LEDs, being Preferably optical elements.
Por otro lado, el tubo 12 citado podría ser totalmente transparente, o tener sólo un sector transparente ocupando una parte de la circunferencia del tubo; o podría tener únicamente dos ventanas enfrentadas, de tamaño suficiente para el paso de los haces de los emisores/receptores.On the other hand, the cited tube 12 could be totally transparent, or have only a transparent sector occupying a part of the circumference of the tube; or could have only two facing windows, of sufficient size for the passing of the beams of the emitters / receivers.
En una realización alternativa, se podrían disponer los emisores y receptores de modo que sobresalieran al menos parcialmente en el interior del conducto, de modo que no sería necesaria la parte transparente.In an alternative embodiment, they could arrange the transmitters and receivers so that they stand out when less partially inside the duct, so that it would not be The transparent part is necessary.
