Abstract

The invention relates to an improvement of a foil bag which comprises flattened and optionally side folded foil bag a portions, provided with a sealed bottom. Such foil bags, usually manufactured from polyethylene (PE) foil, are used in a packaging-machine, which is operated to open and subsequently position the bag into a box, crate or container. The foil bag is provided adjacent to its upper edge with one or more openings ( 6 ) having a diameter which is substantially equal or even greater than the external pin diameter of the support and whereas the foil bag is also provided with at least one foil bag portion provided with one or more incisions ( 10, 11 ) in the foil bag material at a certain distance from the opening in a circumferential direction, in such a way that during the opening process of the folded foil bag during a first step the front of the flat folded foil bag portion is pulled off the pin support and consequently during a second step the rearward flat foil bag portion is pulled off from the pin support in such a way that the incisions will remove the undesirable mutually adherence of the foil bag portions by introducing additional air between the opposite adhering foil bag portions while being pulled off the pin support so that the foil bag is completely and easily and problemless opened starting from the front flat foil bag portion whereafter the rearward flat foil bag portion is pulled off further from the pin support.

Description

Bolsa de material laminar provista de una abertura taladrada e incisiones.Bag of sheet material provided with a drilled opening and incisions.

La invención se refiere a la mejora de una bolsa de material laminar que comprende unas partes de la bolsa de material laminar aplanadas y opcionalmente plegadas en los lados, provistas de un fondo herméticamente cerrado (ver US-A-6 068 128). Este tipo de bolsas, habitualmente fabricadas a partir de lámina de polietileno (PE), se utilizan en una máquina de embalar que opera para abrir y subsecuentemente poner la bolsa en una caja, cajón o contenedor. La patente holandesa de no. 1012033 del solicitante describe una máquina de este tipo.The invention relates to the improvement of a bag of sheet material comprising parts of the bag of sheet material flattened and optionally folded on the sides, provided with a tightly closed bottom (see US-A-6 068 128). This type of bags, usually made from polyethylene sheet (PE), are used in a packaging machine that operates to open and Subsequently put the bag in a box, drawer or container. The Dutch patent no. 1012033 of the applicant describes a machine of this type.

Un legajo de bolsas de material laminar provisto de aberturas taladradas e incisiones se suspende de dos soportes de perno que están insertados a través de agujeros en una máquina conocida. Cuando se usa una bolsa de material laminar en forma de tubo plano plegado las aberturas se taladran a través de dos capas de lámina. Cuando se usa una bolsa de material laminar plegada en los lados las aberturas se taladran cada vez a través de cuatro capas de
lámina.
A bag of sheets of sheet material provided with drilled openings and incisions is suspended from two bolt supports that are inserted through holes in a known machine. When a bag of sheet material in the form of a folded flat tube is used, the openings are drilled through two layers of foil. When a bag of sheet material folded on the sides is used, the openings are drilled each time through four layers of
sheet.

Las aberturas en la bolsa de material laminar y los diámetros de los pernos soportes se ajustan las unas a los otros de tal forma que durante el primer paso, cuando el extremo superior va a ser desplegado de ambos lados de la cara frontal de la bolsa de material laminar, no se tira del mismo simultáneamente a lo largo de la cara trasera de la bolsa de material laminar. Como consecuencia el ciclo de la máquina: apertura - desplegado y sostenido de la bolsa de material laminar puede producir serias irregularidades en el proceso productivo.The openings in the sheet material bag and the diameters of the support bolts fit the ones to the others in such a way that during the first step, when the end upper will be deployed on both sides of the front face of The sheet material bag is not pulled from it simultaneously to along the back side of the sheet material bag. How consequence of the machine cycle: opening - unfolding and Sharp of the bag of laminar material can produce serious irregularities in the production process.

Hasta ahora una medida contra este tipo de irregularidades en la abertura de las bolsas comprende incisiones rectas que se extienden desde el extremo superior de la bolsa hasta una distancia de aproximadamente 2 mm del borde superior de la abertura. Este soporte puente de aproximadamente 2 mm entre la abertura y la incisión puede romperse fácilmente durante el desprendimiento de la parte frontal de la bolsa de material laminar durante su apertura, por ejemplo mediante vacío.So far a measure against this type of irregularities in the opening of the bags includes incisions straight that extend from the top end of the bag to a distance of approximately 2 mm from the upper edge of the opening. This bridge support of approximately 2 mm between the opening and incision can break easily during detachment of the front part of the sheet material bag during opening, for example by vacuum.

Todavía ocurre que en la práctica este tipo de máquina de abrir bolsas de material laminar causa demasiados problemas y de este modo retrasa el proceso de producción y también reduce la velocidad de procesado. Además las herramientas para realizar taladros de diferentes diámetros en la parte frontal y trasera son también diferentes. La circunstancia de que haya insuficiente flujo de aire dentro de la bolsa de material laminar durante su apertura mecánica lleva también a alteraciones no deseables de la producción.It still happens that in practice this type of Laminating bag opening machine causes too many problems and thus delays the production process and also reduces processing speed. In addition the tools for perform drills of different diameters on the front and Rear are also different. The circumstance that there is insufficient air flow inside the sheet material bag during its mechanical opening it also leads to alterations not desirable production.

La invención se basa en considerar la evitación de los problemas de producción mencionados más arriba de las bolsas de material laminar en sí mismas y la evitación de los problemas de apertura de bolsas de material laminar con una máquina del estado de la técnica. Por una parte introduciendo una medida pseudoperturbadora adicional, es decir taladrando aberturas del mismo diámetro en la parte frontal y trasera de la bolsa de material laminar. Por otra parte compensando completamente esta medida pseudoperturbadora con una medida adicional de incremento del flujo de aire dentro de la bolsa de material laminar durante su apertura eliminando el soporte puente entre el final de una incisión y la abertura, y aplicando tales incisiones en la bolsa de material laminar en una zona adyacente o alrededor de las aberturas, de modo que como resultado final la bolsa de material laminar pueda abrirse completamente sin ningún problema o irregularidad durante el proceso de producción.The invention is based on considering avoidance of the production problems mentioned above of the bags of sheet material in themselves and the avoidance of problems of opening of bags of laminar material with a state machine of technique On the one hand introducing a measure additional pseudoperturbadora, that is drilling holes in the same diameter on the front and back of the material bag  laminate. On the other hand completely compensating this measure pseudoperturbadora with an additional measure of flow increase of air inside the sheet material bag during opening removing the bridge support between the end of an incision and the opening, and applying such incisions in the material bag laminate in an adjacent area or around openings, so that as a final result the bag of sheet material can be opened completely without any problem or irregularity during the process of production.

La invención se caracteriza porque la bolsa de material laminar dispone, cerca de su extremo superior, de una o más aberturas que tienen un diámetro que es esencialmente igual o incluso mayor que el diámetro externo del perno soporte, mientras que la bolsa de material laminar también dispone de por lo menos una parte de la bolsa de material laminar con una o más incisiones en el material laminar de la bolsa a cierta distancia desde la abertura en dirección circunferencial, de tal modo que durante el proceso de apertura de la bolsa de material laminar cerrada, durante un primer paso, la parte frontal de la bolsa plana de material laminar es desprendida del perno soporte y consecuentemente durante un segundo paso la parte trasera plana de la bolsa de material laminar es desprendida del perno soporte, de tal modo que las incisiones eliminarán las indeseables mutuas adherencias de las partes de la bolsa de material laminar introduciendo aire adicional entre las partes opuestas de la bolsa de material laminar que se adhieran mientras que son desprendidas del soporte perno, con lo que la bolsa de material laminar es abierta completa y fácilmente y sin problemas empezando desde la parte frontal plana de la bolsa de material laminar, después de lo cual la parte trasera plana de la bolsa de material laminar es desprendida adicionalmente del perno soporte.The invention is characterized in that the bag of sheet material has, near its upper end, one or more openings that have a diameter that is essentially the same or even larger than the outer diameter of the support bolt, while that the bag of sheet material also has at least one part of the bag of sheet material with one or more incisions in the sheet material of the bag some distance from the opening in the circumferential direction, such that during opening process of the closed sheet material bag, during a first step, the front of the flat bag of sheet material is detached from the support bolt and consequently during a second step the flat back of the bag of sheet material is detached from the support bolt, of such that the incisions will eliminate undesirable mutuals adhesions of the parts of the sheet material bag introducing additional air between the opposite parts of the bag of sheet material that adhere while they are detached of the bolt support, so that the bag of laminar material is open completely and easily and without problems starting from the flat front of the sheet material bag, after which flat back of the sheet material bag is additionally detached from the support bolt.

En la realización más arriba descrita se utiliza una bolsa de material laminar, aplanada o plegada en los lados, con unas dimensiones exteriores de 60 x 55 cm y un diámetro de abertura de 10 mm, en la que han sido practicadas dos aberturas a una distancia de 20 mm desde el borde superior de la bolsa de material laminar.In the embodiment described above, it is used a bag of sheet material, flattened or folded on the sides, with external dimensions of 60 x 55 cm and an opening diameter 10 mm, in which two openings have been made to one 20 mm distance from the top edge of the material bag laminate.

En el caso de utilización de formas de bolsa de material laminar diferentes, por ejemplo de una bolsa cónica, puede disponerse una sola abertura.In the case of using bag forms of different sheet material, for example from a conical bag, can dispose a single opening.

Preferiblemente la parte trasera plana de la bolsa de material laminar no presenta incisiones que se extiendan desde el borde superior hasta la abertura. Cuando la parte trasera de la bolsa no presenta incisiones, particularmente cuando no tiene incisiones entre las aberturas y el borde superior de la bolsa de material laminar, la parte trasera de la bolsa puede ser que no permita ser fácilmente desprendida de los pernos soporte, por lo que como resultado se mejora la apertura y consecuentemente el desplegado de la bolsa, y de ahí también el posicionado de la bolsa desplegada y abierta en una caja, cajón o contenedor.Preferably the flat back of the Laminar material bag does not have incisions that extend from the upper edge to the opening. When the rear The bag has no incisions, particularly when it has no incisions between the openings and the top edge of the bag sheet material, the back of the bag may not allow to be easily detached from the support bolts, so  as a result the opening is improved and consequently the deployed from the bag, and hence also the positioning of the bag unfolded and open in a box, drawer or container.

Particularmente la parte plana frontal de la bolsa de material laminar está provista de unas incisiones que se extienden desde el borde superior hasta la abertura. De esta forma la máquina de abrir bolsas desprenderá fácilmente la parte frontal de la bolsa de material laminar desde los pernos soporte, con poca probabilidad de fallos.Particularly the flat front part of the bag of laminar material is provided with incisions that are They extend from the upper edge to the opening. Thus The bag opener will easily detach the front of the bag of sheet material from the support bolts, with little probability of failures.

Más particularmente la parte frontal de los pliegues laterales dispone de aberturas e incisiones similares a los de la parte plana frontal de las bolsas de material laminar y preferiblemente la parte trasera de los pliegues laterales dispone de aberturas e incisiones similares a los de la parte trasera plana de la lámina. Para una bolsa de material laminar provista de pliegues laterales durante su producción es técnicamente favorable producir el pliegue lateral frontal junto con, e idénticamente igual a, la parte delantera de la bolsa de material laminar y producir el pliegue lateral trasero junto con, e idénticamente igual a, la parte trasera de la bolsa de material laminar. También es ventajoso proveer el pliegue lateral frontal con una incisión, y así este pliegue también es fácilmente desprendido de los pernos soporte.More particularly the front of the lateral folds have openings and incisions similar to those of the flat front part of the bags of sheet material and preferably the back of the side folds has of openings and incisions similar to those of the flat back of the sheet. For a bag of sheet material provided with lateral folds during its production is technically favorable produce the front side fold along with, and identically the same a, the front of the sheet material bag and produce the rear side fold along with, and identically equal to, the part back of the bag of laminar material. It is also advantageous provide the frontal lateral fold with an incision, and so this Fold is also easily detached from the support bolts.

Con respecto a la invención es evidente que la posición de las incisiones y también su forma externa pueden variar mucho, como por ejemplo una perforación de tamaño menor, cuando se cumple la condición de que el aire adicional pueda introducirse en la bolsa de una forma rápida durante su apertura mediante la fijación suspendida en los pernos soporte. Todas las diferentes realizaciones se explican en detalle más adelante en las reivindicaciones.With respect to the invention it is evident that the position of the incisions and also their external shape may vary a lot, such as a smaller perforation, when meets the condition that additional air can be introduced into the bag quickly during opening by suspended fixing on the support bolts. All the different realizations are explained in detail later in the claims.

A continuación se explica adicionalmente la invención mediante dibujos, en los que:The following explains the invention by drawings, in which:

La Figura 1 es una realización de una bolsa de material laminar con pliegues laterales que tiene una abertura con incisiones y en una perspectiva esquemática desde arriba que no muestra el fondo herméticamente cerrado;Figure 1 is an embodiment of a bag of sheet material with side folds that has an opening with incisions and in a schematic perspective from above that does not shows the tightly closed bottom;

La Figura 2 muestra, en una vista frontal parcial, un tipo de abertura provisto de incisiones en, o cerca de, el extremo superior en el lado frontal de la bolsa de material laminar según la Figura 1;Figure 2 shows, in a front view partial, a type of opening provided with incisions in, or near, the upper end on the front side of the material bag laminate according to Figure 1;

La Figura 3 muestra, en una vista frontal parcial, un tipo de abertura de bolsa de material laminar provisto de incisiones en forma de perforaciones;Figure 3 shows, in a front view partial, a type of laminar material bag opening provided of incisions in the form of perforations;

La Figura 4 muestra una línea curvada como incisión en una abertura; yFigure 4 shows a curved line as incision in an opening; Y

La Figura 5 muestra una bolsa de material laminar provista solamente de incisiones en la parte frontal de la bolsa plegable.Figure 5 shows a bag of material laminar provided only with incisions in the front of the folding bag

La Figura 1 muestra una bolsa 1 de material laminar parcialmente desplegada y abierta que dispone de aberturas pasantes 6, 6.1, 6.2, 6.3 y 7, 7.1, 7.2, 7.3 en el lado frontal 2, el lado trasero 3 y los pliegues laterales 4 y 5. Como explicación, las líneas centrales 8 y 9 de dos pernos soporte están dibujadas donde un legajo de bolsas de material laminar plegadas en los lados está suspendido y montado en la máquina de abrir bolsas según la patente concedida del solicitante. En esta realización se muestran algunas incisiones 10, 11 y así se consigue el propósito de la introducción adicional de aire en la bolsa 1 de material laminar durante su apertura. Las incisiones 10 y 11 son líneas rectas y se extienden respectivamente desde el borde superior 12 de la bolsa 1 de material laminar a los extremos circunferenciales 13 y 14 de las respectivas aberturas 6 y 7. Además, tal como se muestra en la Figura 2, se dispone de algunas incisiones adicionales 15,16 alrededor de las aberturas 6 y 7 para evitar la indeseable mutua adherencia de las partes de la bolsa plegable introduciendo aire adicional en la bolsa mientras está siendo desprendida del perno soporte.Figure 1 shows a bag 1 of material partially unfolded and open sheet that has openings interns 6, 6.1, 6.2, 6.3 and 7, 7.1, 7.2, 7.3 on the front side 2, the back side 3 and the side folds 4 and 5. As an explanation, center lines 8 and 9 of two support bolts are drawn where a bundle of bags of laminated material folded on the sides It is suspended and mounted on the bag-opening machine according to the patent granted from the applicant. In this embodiment they are shown some incisions 10, 11 and so the purpose of the additional introduction of air into the bag 1 of sheet material during its opening Incisions 10 and 11 are straight lines and are extend respectively from the upper edge 12 of the bag 1 of sheet material at the circumferential ends 13 and 14 of the respective openings 6 and 7. In addition, as shown in the Figure 2, some additional incisions are available 15,16 around openings 6 and 7 to avoid mutual undesirable adhesion of the parts of the folding bag by introducing air additional in the bag while being removed from the bolt support.

La Figura 3 muestra el borde superior de una bolsa 17 plana de material laminar provista de aberturas 18, 19 y una incisión recta 20 y 21 respectivamente. En esta realización hay algunas perforaciones 22, 23 alrededor de las aberturas 18,19 que tienen el objetivo de aumentar el flujo de aire durante el desprendimiento de la bolsa de material laminar de su perno soporte. La posición y las dimensiones de las incisiones y/o de las perforaciones pueden determinarse mediante experimentación si se desea, y también dependen de, y están influenciadas por, el área de conexión y el tamaño de la unidad mecánica de vacío, mediante la cual se ejerce una fuerza de succión en el lado frontal de la bolsa de material laminar a abrir, con lo cual también está relacionado el desplazamiento total de la unidad mecánica de vacío mientras se retira la bolsa de material laminar.Figure 3 shows the upper edge of a flat bag 17 of sheet material provided with openings 18, 19 and a straight incision 20 and 21 respectively. In this embodiment there are some perforations 22, 23 around openings 18,19 that they aim to increase the air flow during the detachment of the sheet material bag from its bolt support. The position and dimensions of the incisions and / or the perforations can be determined by experimentation if you want, and also depend on, and are influenced by, the area of connection and size of the mechanical vacuum unit, by means of the which exerts a suction force on the front side of the bag of sheet material to open, which is also related the total displacement of the mechanical vacuum unit while Remove the bag of sheet material.

La Figura 4 muestra una incisión curva 24. Evidentemente la longitud de esta incisión curva 24 entre el punto A y el B es mayor que la longitud de una incisión recta 25 entre los mismos puntos A y B. Por consiguiente el paso del flujo de aire es mayor para una línea curvada 24 y como resultado es más ventajoso para el propósito previsto. Si se prefiere, una línea de incisión 10, 11, 20, 21 puede extenderse por ejemplo recta desde el borde superior de la bolsa de material laminar hasta el borde circunferencial superior de la abertura y entonces puede extenderse más, en una longitud de algunos mm a unos dos cm, más allá del borde circunferencial inferior de la abertura.Figure 4 shows a curved incision 24. Obviously the length of this incision curves 24 between the point A and B is greater than the length of a straight incision 25 between the same points A and B. Therefore the air flow passage is larger for a curved line 24 and as a result it is more advantageous For the intended purpose. If preferred, an incision line 10, 11, 20, 21 can extend for example straight from the edge upper bag of laminar material to the edge upper circumferential of the opening and then it can extend more, in a length of some mm to about two cm, beyond the edge lower circumferential of the opening.

La Figura 5 muestra una realización especial de la bolsa de material laminar con números de referencia correspondientes a la Figura 1, no estando provista la parte trasera de la bolsa de material laminar o el lado trasero 3 de una incisión recta, y así el lado trasero podrá desprenderse del perno soporte menos fácilmente y como resultado la bolsa de material laminar podrá abrirse y desplegarse más fácilmente y de una forma más fiable en la máquina de abrir bolsas. La parte frontal de la bolsa de material laminar o el lado frontal 2, como resultado, está provisto de unas incisiones rectas 10 y 11 que se extienden desde el borde superior de la bolsa de material laminar hasta las aberturas 6 y 7. Las aberturas 6.2 y 7.2 de los pliegues laterales traseros no están provistas de incisiones similares a las de los lados traseros 3 por razones técnicas de producción. Debido a que el desprendimiento de los pliegues del lado trasero de los pernos soporte es menos crítico durante la operación, también es posible proveer el pliegue de este lado con incisiones sin aumentar las posibilidades de tener problemas en la máquina.Figure 5 shows a special embodiment of laminar material bag with reference numbers corresponding to Figure 1, the part not being provided back of the bag of laminar material or the back side 3 of a straight incision, and so the back side can detach from the bolt support less easily and as a result the material bag laminate can be opened and deployed more easily and in a way more reliable in the bag opening machine. The front of the bag of laminar material or the front side 2, as a result, is provided with straight incisions 10 and 11 that extend from the upper edge of the sheet material bag to the openings 6 and 7. The openings 6.2 and 7.2 of the rear side folds are not they are provided with incisions similar to those on the back sides 3 for technical production reasons. Because the detachment of the folds on the back side of the bolts support is less critical during operation, it is also possible provide the crease on this side with incisions without increasing the chances of having machine problems.

A pesar de que en las realizaciones descritas anteriormente se asuma que las aberturas 6 y 7 son circulares también es posible disponer aberturas no circulares en la bolsa de material laminar de la Figura 1 y de la Figura 5. Por ejemplo son posibles aberturas elípticas, que pueden cooperar juntas con pernos soporte de sección circular o elíptica. También pueden utilizarse opcionalmente otras aberturas totalmente cerradas y poligonales mientras estén adaptadas a la forma de los pernos soporte, siempre y cuando el movimiento requerido de desprendimiento por cizalladura y tracción de la bolsa de material laminar no sea impedido durante su desplegado.Although in the described embodiments previously assume that openings 6 and 7 are circular it is also possible to arrange non-circular openings in the bag of sheet material of Figure 1 and Figure 5. For example they are possible elliptical openings, which can cooperate together with bolts support circular or elliptical section. Can also be used optionally other fully closed and polygonal openings as long as they are adapted to the shape of the support bolts, provided when the required shear movement required and traction of the sheet material bag is not impeded during unfolded.
