SISTEMA DE FABRICACIÓN Y MONTAJE DE ASAS PARA SACOS DE MANUFACTURING AND ASSEMBLY SYSTEM FOR HANDLES

PAPEL- OBJETO DE LA INVENCIÓN. La siguiente invención, según se expresa en el enunciado de la presente memoria descriptiva, se refiere a un sistema de fabricación y montaje de asas para sacos de papel, de forma que en la fabricación de las asas, se obtienen conjuntos individuales definidos por un soporte constituido por dos láminas de papel de distinta anchura, unidas entre sí por pegado, entre las que se posiciona y fija el cordón de asido en sí, constituido por una tira de papel de una sola capa rizado y plano, de manera que las asas son susceptibles de montarse en un lateral del fondo del correspondiente saco, el cual preferentemente será del tipo de sacos de fondo plano.PAPER- OBJECT OF THE INVENTION. The following invention, as expressed in the statement of this specification, refers to a manufacturing and assembly system for handles for paper bags, so that in the manufacture of the handles, individual sets defined by a support are obtained. consisting of two sheets of paper of different widths, joined together by gluing, between which the grip cord itself is positioned and fixed, consisting of a single-layer curled and flat paper strip, so that the handles are capable of mounting on one side of the bottom of the corresponding bag, which will preferably be of the flat-bottom bag type.

Mediante el sistema que se presenta, se trata de fabricar asas en un proceso independiente al de fabricación de los sacos de papel, de forma que en un proceso posterior las asas puedan ser montadas en aquellos sacos que se desee, obteniendo la posibilidad de tener sacos convencionales sin asa o sacos provistos de un asa en un lateral de su fondo. La incorporación de un asa en un lateral de su fondo de sacos de cierto peso tiene por objeto permitir una mejor manipulación de los sacos en su transporte y almacenaje, y principalmente en el vaciado dosificado de los mismos, al facilitar un adecuado asido de ios sacos que permitirá el vertido dosificado de la cantidad deseada. Las asas fabricadas según conjuntos individuales, igualmente, son susceptibles de montarse e incorporarse en todo tipo de bolsas de papel, quedando montadas en un proceso posterior al de su fabricación en relación a su boca.By means of the system presented, it is a matter of manufacturing handles in a process independent from that of manufacturing paper bags, so that in a subsequent process the handles can be mounted in those bags that are desired, obtaining the possibility of having bags Conventional without handles or bags with a handle on one side of the bottom. The incorporation of a handle on the side of its bottom of bags of a certain weight is intended to allow better handling of the bags in their transport and storage, and especially in the dosed emptying of the same, by facilitating proper gripping of the bags that will allow the dosed discharge of the desired quantity. The handles manufactured according to individual sets, likewise, are capable of being mounted and incorporated in all types of paper bags, being mounted in a process subsequent to that of their manufacture in relation to their mouth.

CAMPO DE APLICACIÓN. El montaje de asas en el fondo lateral de sacos, es de aplicación preferente para su incorporación en sacos de papel de fondo plano, que pueden contener muy diversos productos, facilitando la manipulación en su transporte y almacenaje, así como, principalmente, en el vaciado dosificado de los mismos. Asimismo, las asas obtenidas individualmente son de aplicación para su montaje en todo tipo de bolsas de papel, pudiendo ser incorporadas en un proceso posterior al de fabricación de las bolsas, quedando en este caso montadas en las caras laterales de la bolsa en relación a su boca. ANTECEDENTES DE LA INVENCIÓN.SCOPE. The mounting of handles on the side bottom of bags is of preferred application for incorporation into flat-bottomed paper bags, which can contain a wide variety of products, facilitating handling during transport and storage, as well as, mainly, when emptying. dosed of the same. Also, the handles obtained individually are applicable for mounting on all types of paper bags, being able to be incorporated in a process subsequent to the manufacture of the bags, being in this case mounted on the side faces of the bag in relation to its mouth. BACKGROUND OF THE INVENTION.

En el mercado existen una gran diversidad de sacos, pudiendo ser los sacos de distintos materiales y capacidad para contener muy diversos productos, de forma que uno de los inconvenientes que se presenta es su dificultad en el manejo para su transporte y almacenaje, así como para su vaciado y más aún cuando este debe ser dosificado.In the market there is a great diversity of bags, being able to be bags of different materials and capacity to contain very diverse products, so that one of the drawbacks that occurs is their difficulty in handling for transport and storage, as well as for its emptying and even more so when it must be dosed.

Todo ello, es como consecuencia de que normalmente los sacos no tienen elementos apropiados para su asido, acentuándose dicho inconveniente en aquellos sacos de llenado por válvula, dado que el saco, una vez ha quedado totalmente lleno, queda definiendo un cuerpo compacto carente de salientes y elementos de asido, por lo que su manipulación es dificultosa.All this is as a consequence of the fact that the bags do not normally have appropriate elements for their grip, accentuating said drawback in those valve filling bags, since the bag, once it has been fully filled, defines a compact body without protrusions and grip elements, so its handling is difficult.

De esta forma, suele suceder que al coger un saco para su transporte o vaciado se resbale, siendo dificultosa su manipulación y sujeción, agravándose dicha situación cuando se trata de realizar un vaciado dosificado, ya que en numerosas ocasiones se acaba vertiendo una cantidad excesiva, no deseada, finalizando parte del producto derramado por el suelo, con el inconveniente que ello representa, tanto económicamente por la perdida de producto como por el problema higiénico que ello puede representar. Por otra parte, podemos citar la Patente alemana DE-A-3614442 en la que se reivindica un saco de fondo cruzado con asidero para llevar, dispuesto en la zona del fondo del saco, comprendiendo una lámina que por un extremo se fija al fondo cruzado del saco, y por su otro extremo presenta unas ranuras y sobresale libremente del canto del contorno lateral del saco, de forma que la lámina, de un material flexible de alta resistencia a la rotura, sirve de asidero al cogerla por la zona de las ranuras.In this way, it usually happens that when taking a bag for transport or emptying it slips, making it difficult to handle and hold it, aggravating this situation when it comes to performing a dosed emptying, since on numerous occasions it ends up pouring an excessive amount, unwanted, ending part of the product spilled on the floor, with the drawback that this represents, both economically due to the loss of product and the hygienic problem that this may represent. On the other hand, we can cite the German patent DE-A-3614442 in which a cross-bottom bag with a carrying handle is claimed, arranged in the area of the bottom of the bag, comprising a sheet that at one end is fixed to the crossed bottom of the bag, and at its other end it has grooves and freely protrudes from the edge of the lateral contour of the bag, so that the sheet, made of a flexible material with high resistance to breakage, serves as a handle when grasping it in the area of the grooves .

De esta forma, la lámina es incorporada y montada en el fondo cruzado de los sacos durante el propio proceso de fabricación de los sacos, quedando dispuesta entre las solapas de ambos lados del fondo del saco cruzado y fijándose por pegado.In this way, the sheet is incorporated and mounted on the crossed bottom of the bags during the bag manufacturing process itself, being placed between the flaps on both sides of the bottom of the crossed bag and fixing by gluing.

Así, la lámina que actúa de asidero del saco es incorporada durante el propio proceso automático de fabricación de los sacos, y la zona extrema ranurada de dicha lámina de asido queda sobresaliendo del contorno lateral del saco.Thus, the sheet that acts as a handle for the bag is incorporated during the automatic manufacturing process of the bags, and the grooved end area of said grip sheet is protruding from the lateral contour of the bag.

DESCRIPCIÓN DE LA INVENCIÓN. En la presente memoria se describe un sistema de fabricación y montaje de asas para sacos de papel, siendo de especial utilidad para la incorporación y montaje de las asas en sacos de papel de fondo plano, de manera que el sistema de fabricación de las asas comprende medios para el corte a la medida deseada del cordón de asido, el cual está definido por una tira de papel de una sola capa rizado y plano, conformado en bobinas, medios para el conformado del soporte del cordón de asido, constituido por dos láminas de papel de diferente anchura, fijándose el citado cordón por pegado entre ambas láminas, definiendo el asa en sí, y medios para el montaje de las asas en el correspondiente lateral de los respectivos sacos posterior e independientemente al proceso de fabricación de los sacos.DESCRIPTION OF THE INVENTION. This document describes a system for manufacturing and mounting handles for paper bags, being especially useful for incorporating and mounting the handles in flat-bottomed paper bags, so that the system for manufacturing the handles comprises means for cutting to the desired length of the grasping cord, which is defined by a curled and flat single-layer paper strip, formed into coils, means for forming the support of the grasping cord, consisting of two sheets of paper of different widths, the aforementioned cord being fixed by gluing between both sheets, defining the handle itself, and means for mounting the handles on the corresponding side of the respective back bags and independently of the bag manufacturing process.

Los medios para el corte a la medida deseada del cordón de asido, a partir de la correspondiente bobina, se definen por un cilindro provisto en el extremo libre de su émbolo de una pinza para el amarre y estirado del cordón la longitud deseada estando tensado dicho cordón al ser pasante por unos rodillos de presión y siendo cortado por medio de una cizalla actuable por un cilindro. Lógicamente, la cizalla puede estar actuada por cualquier otro medio que le transmita el movimiento para el corte del cordón y su retorno a la posición original.The means for cutting the gripping cord to the desired size, starting from the corresponding coil, are defined by a cylinder provided at the free end of its piston with a clamp for tying and stretching the cord the desired length, said tension being tightened cord being passed through pressure rollers and being cut by means of a shear that can be actuated by a cylinder. Logically, the shear can be operated by any other means that transmits the movement to cut the cord and return it to its original position.

Los medios para el conformado del soporte de fijación del cordón de asido se definen por dos bobinas de papel de distinta anchura, siendo las tiras de papel de dichas bobinas conducidas y adecuadamente tensadas entre una serie de rodillos, confluyendo a un soporte, enfrentadas por sus caras de adosamiento para su unión por pegado con la interposición del cordón de asido debidamente doblado, respecto de sus extremos, de forma que en relación a la superficie de adosamiento de ambas tiras de papel se produce una aplicación, según un proceso continuo, de unos cordones de cola desfasados entre sí los de cara tira de papel y conduciéndose las tiras adosadas y pegadas a su paso por una prensa, para ser finalmente cortadas individualmente por una cizalla. Las tiras de papel de distinta anchura procedentes de las bobinas, se adosan respecto de uno de sus laterales, disponiendo el cordón de asido doblado 180° respecto de sus extremos, transversalmente al avance de las tiras en relación a la tira de mayor anchura.The means for forming the support for fixing the grip cord are defined by two paper reels of different width, the paper strips of said reels being driven and suitably tensioned between a series of rollers, converging on a support, facing each other. Attachment faces for their bonding by gluing with the interposition of the appropriately folded grasping cord, with respect to their ends, so that in relation to the attachment surface of both strips of paper, an application occurs, according to a continuous process, of tail cords out of phase with the face strip of paper and leading the strips attached and glued as it passes through a press, to be finally cut individually by a shear. The paper strips of different widths coming from the reels are attached to one of their sides, arranging the grip cord folded 180 ° with respect to its ends, transversely to the advance of the strips in relation to the widest strip.

Los medios para el montaje de las asas en el correspondiente lateral de los respectivos sacos se definen por una cinta transportadora, con un alimentador de sacos y un alimentador de asas, de forma que los sacos son alimentadas por un extremo de la cinta transportadora, y en su avance por ella se les aplica ,en un lateral de su fondo, unos cordones de cola, siendo posteriormente dispuestas las asas por medio de un brazo doble giratorio, que en relación a la lámina de mayor anchura las dispone sobre el lateral del fondo del saco en el que se han aplicado los cordones de cola, siendo conducidos en su avance para su prensado al paso por unos rodillos transversales y final almacenaje.The means for mounting the handles on the corresponding side of the respective bags are defined by a conveyor belt, with a bag feeder and a handle feeder, so that the bags are fed by one end of the conveyor belt, and in its advance through it, glue cords are applied to one side of its bottom, the handles being subsequently arranged by means of a double rotating arm, which in relation to the sheet of greater width has them on the side of the bottom of the bag in which the glue cords have been applied, being led in their advance for pressing to the passage by transversal rollers and final storage.

El alimentador de los sacos a la cinta transportadora se define por un soporte provisto de unas ventosas para el amarre de los sacos y su traslado a la cinta transportadora al estar accionado por un cilindro. El alimentador de las asas para su montaje en los respectivos sacos se define por una plataforma montada en un tornillo sinfín accionado por un motor para su elevación progresiva, permitiendo que las asas apiladas en la plataforma sean transportadas por el brazo doble giratorio hacia el lateral correspondiente del saco. El brazo doble giratorio de transporte de las asas desde el alimentador de las mismas al lateral correspondiente del fondo del saco es desplazable verticalmente en el amarre y liberación de las asas y en su giro de 180° permite en un movimiento simultáneo amarrar un asa del aiimentador y liberar el asa correspondiente en el lateral del saco en el que se va montar la otra asa transportada por el brazo doble.The feeder of the bags to the conveyor belt is defined by a support provided with suction cups to tie the bags and transfer them to the conveyor belt when powered by a cylinder. The feeder of the handles for mounting in the respective bags is defined by a platform mounted on a worm screw powered by a motor for its progressive elevation, allowing the handles stacked on the platform to be transported by the double rotating arm to the corresponding side from the sack. The double rotating handle transport arm from the feeder to the corresponding side of the bottom of the bag is vertically movable in the mooring and release of the handles and in its 180 ° rotation it allows in a simultaneous movement to tie a handle of the feeder and release the corresponding handle on the side of the bag on which the other handle carried by the double arm is to be mounted.

Figure 8. Shows a view of the bottom of a bag which in a A handle has been mounted on the side, observing how the handle remains without protruding from the contour of the bag and when it is grasped, the traction occurs with respect to the outer side of the smaller width paper strip. DESCRIPTION OF A PREFERRED EMBODIMENT. In view of the aforementioned figures and according to the numbering adopted, we can see how the grasping cord is cut to size from coil 1, cord 2 being defined by a flat and curled single-layer paper strip , so that the cord 2 will be cut to the desired measure, the means for obtaining it being defined by a cylinder 4 at the end of whose piston 5 has a clamp 6 that ties the free end of the cord 2 coming from the coil 1 , stretching it in the retraction of the plunger to be cut by the shear 7. The cylinder can be replaced by a similar means. The cord 2 is duly tensioned as it is passed through tensioning rollers 3 and the cut will be made to the desired measure according to the stroke of the piston 5 of the cylinder 4.

Así, el corte del cordón 2 se realizará de acuerdo a la longitud deseada, que es programada automáticamente mediante le pulsador 9 relativo al sistema de control, disponiendo, igualmente, de los correspondientes pulsadores de puesta en marcha-paro, pulsador de inicio de las operaciones de corte, y otras funciones más.Thus, the cutting of the cord 2 will be carried out according to the desired length, which is automatically programmed by means of the button 9 related to the control system, also having the corresponding start-stop buttons, start button of the cutting operations, and other functions.

Al definir el cordón 2 según una única tira de papel rizado se permite que el esfuerzo de tracción se reparta perfectamente y el mismo aguante el peso de aquellos sacos convencionales de mayor volumen y peso.By defining cord 2 according to a single strip of curled paper, the traction effort is allowed to be distributed perfectly and it can withstand the weight of those conventional bags of greater volume and weight.

Las asas 10 fabricadas se conforman por un conjunto definido por un soporte constituido por dos láminas obtenidas a partir de respectivas tiras 11 y 12 de papel en bobina, de distinta anchura, unidas entre sí por pegado, con la interposición del cordón 2 de asido debidamente doblado.The handles 10 manufactured are made up of a set defined by a support consisting of two sheets obtained from respective strips 11 and 12 of reel paper, of different widths, joined together by gluing, with the interposition of the gripping cord 2 properly bent.

Así, los medios para la obtención de las asas 10 obtenidas individualmente, se constituyen por dos bobinas 13 y 14 de papel, según las tiras 11 y 12 de distinta anchura, tensando adecuadamente las tiras en su paso y conducción por una serie de rodillos, hasta ser conducidas para enfrentarse entre sí enrasadas por uno de sus lados para fijarse entre sí por pegado con la interposición del correspondiente cordón 2 de asido.Thus, the means for obtaining the handles 10 obtained individually are made up of two reels 13 and 14 of paper, according to the strips 11 and 12 of different widths, suitably tensioning the strips in their passage and driving by a series of rollers, until they are led to face each other flush on one side to fix to each other by gluing with the interposition of the corresponding grip cord 2.

De esta forma, a las tiras 11 y 12 se les incorporan unos cordones 15 y 16 de cola, por medio de correspondientes aplicadores 17 y 18 respecto de sus caras de adosamiento, quedando los citados cordones 15 y 16 desfasados entre sí.In this way, strips 11 and 12 are fitted with glue cords 15 and 16, by means of corresponding applicators 17 and 18 with respect to their attachment faces, said cords 15 and 16 being out of phase with each other.

La aplicación de los cordones 15 y 16 de cola en las tiras 11 y 12, de las bobinas 13 y 14, se realiza en un proceso continuo, de manera que, manual o automáticamente, se dispone entre las tiras 11 y 12, los cordones 2 de asido adecuadamente cortados, haciendo pasar las dos tiras 11 y 12 con la previa interposición de los cordones 2 incorporados en la adecuada posición 19 del avance de las tiras 11 y 12, por una prensa 20 y ser cortada respecto de la posición 21 deseada por la cizalla 22 quedando así conformados los conjuntos 10 individuales de las asas. Las asas 10 definidas por el conjunto de las tiras 11 y 12 con interposición del cordón 2 de asido, constituidas individualmente, están preparadas para su incorporación y montaje en el correspondiente lateral del fondo 23 de los sacos 24 disponiendo y fijando los conjuntos 10 de las asas respecto de la cara libre de la tira 12 de mayor anchura. Para el proceso de montaje de las asas 10 en los sacos 24, se dispone de unos medios constituidos por una cinta transportadora 25 por uno de cuyos extremos se produce la alimentación de los sacos, debidamente posicionados, en los que se va a montar la correspondiente asa, y en un punto de su avance por la cinta transportadora se produce la alimentación de las asas 10.The application of the glue cords 15 and 16 on strips 11 and 12, on coils 13 and 14, is carried out in a continuous process, so that, manually or automatically, the cords are arranged between strips 11 and 12. 2 gripping suitably cut, passing the two strips 11 and 12 with the prior interposition of the cords 2 incorporated in the appropriate position 19 of the advance of the strips 11 and 12, by a press 20 and being cut with respect to the desired position 21 by the shear 22 thus forming the individual sets 10 of the handles. The handles 10 defined by the set of the strips 11 and 12 with interposition of the grip cord 2, individually constituted, are prepared for their incorporation and mounting on the corresponding side of the bottom 23 of the bags 24 by arranging and fixing the sets 10 of the handles with respect to the free face of the widest strip 12. For the assembly process of the handles 10 in the bags 24, there are means consisting of a conveyor belt 25 at one end of which the feeding of the bags, properly positioned, in which the corresponding one is to be mounted, is produced. handle, and at a point of its advance on the conveyor belt the feeding of the handles 10 takes place.

Así, los sacos 24, vacíos y doblados convencionalmente, están dispuestos en el soporte 26 y el alimentador 27 los traslada a la cinta transportadora 25, constituyéndose el alimentador 27 por un soporte provisto de unas ventosas para el amarre de los sacos, estando el citado soporte 26 accionado por un cilindro 28, de forma que en el avance de los sacos por medio de un aplicador 29 de cola se incorpora la cola de pegado de las asas 10 en el correspondiente lateral del fondo 23 de los sacos 24, accediendo los sacos 24 al módulo 30 de pegado de las asas 10 donde se encuentra el alimentador 31 de las asas 10. El alimentador 31 de las asas 10 se define por un soporte 32 con un tornillo sinfín 34 en el que monta la plataforma 33 de ubicación de las tasas 10, actuando sobre el tornillo sinfín 34 un motor que producirá la progresiva elevación de la plataforma 33 para la alimentación de las asas 10. Las asas 10 son amarradas por un brazo doble 35 al disponer de respectiva ventosas 36 de manera que el brazo doble 35 en un proceso simultáneo a la vez que amarra un asa del alimentador 31 deja un asa 10 en el lateral correspondiente del saco en el que se monta el asa en un movimiento de descenso y ascenso del brazo doble 35 giratorio. A la salida del módulo 30 de montaje de las asas 10 por pegado, los sacos pasan por unos rodillos 37 transversales que aseguran la unión del asa, y finalmente los sacos con el asa correspondiente son desalojados de la cinta transportadora 25 hacia el soporte 38 para su paletizado. Thus, the sacks 24, empty and conventionally folded, are arranged on the support 26 and the feeder 27 transfers them to the conveyor belt 25, the feeder 27 being constituted by a support provided with suction cups for tying the sacks, the aforementioned being support 26 actuated by a cylinder 28, so that when the bags advance by means of a glue applicator 29, the glue for the handles 10 is incorporated in the corresponding side of the bottom 23 of the bags 24, accessing the bags 24 to the module 30 for gluing the handles 10 where the feeder 31 of the handles 10 is located. The feeder 31 of the handles 10 is defined by a support 32 with a worm screw 34 on which the platform 33 locates the fees 10, acting on the worm screw 34 a motor that will produce the progressive elevation of the platform 33 to feed the handles 10. The handles 10 are tied by a double arm 35 by having respective suction cups 36 so that the double arm 35 in a simultaneous process while tying a handle of the feeder 31 leaves a handle 10 on the corresponding side of the bag in which the handle is mounted in one movement lowering and ascending double swivel arm 35. At the outlet of the module 30 for mounting the handles 10 by gluing, the bags pass through transversal rollers 37 that ensure the union of the handle, and finally the bags with the corresponding handle are dislodged from the conveyor belt 25 towards the support 38 to your palletizing.
