DESCRIPCIONDESCRIPTION
Maquina de pegado de cajas plegables para fabricar cajas plegables a partir de preformas cortadas.Folding boxes gluing machine to manufacture folding boxes from cut preforms.
La presente invencion se refiere a una maquina de pegado de cajas plegables segun el preambulo de la reivindicacion 1.The present invention relates to a machine for gluing folding boxes according to the preamble of claim 1.
Las maquinas de pegado de cajas plegables para fabricar cajas plegables a partir de preformas cortadas presentan de manera conocida por lo menos las siguientes estaciones de tratamiento:Folding box gluing machines for manufacturing folding boxes from cut preforms have known at least the following treatment stations:
- un alimentador que retira sucesivamente de una pila con alta velocidad las preformas cortadas a procesar y las suministra individualmente a la siguiente estacion de tratamiento,- a feeder that successively removes cut preforms to be processed from a stack with high speed and supplies them individually to the next treatment station,
- una estacion de plegado en la que las partes de preformas cortadas provistas de una tira adhesiva se pliegan 180°, es decir, se pliegan, para producir una union adhesiva,- a folding station in which the parts of cut preforms provided with an adhesive strip are folded 180 °, that is, folded, to produce an adhesive joint,
- una estacion de transferencia que suministra al siguiente dispositivo de recogida y prensado las preformas cortadas plegadas provistas de costuras adhesivas aun no fraguadas, con todas las partes de las preformas exactamente orientadas, y- a transfer station that supplies folded cut preforms provided with adhesive seams not yet set to the next collection and pressing device, with all parts of the preforms accurately oriented, and
- un dispositivo de recogida y prensado en el que se forma primeramente una corriente imbricada de preformas cortadas plegadas que se mantiene seguidamente a presion durante algun tiempo entre bandas de prensado para que fraguen las costuras adhesivas.- a collection and pressing device in which an imbricated stream of folded cut preforms is first formed, which is then held under pressure for some time between pressing bands so that the adhesive seams will set.
Las preformas cortadas se transportan a traves de las estaciones individuales por medios de transporte accionados. Como medios de transporte accionados se utilizan dos o tres pares de correas de transporte que estan dispuestas a cierta distancia transversal de modo que lleven las preformas cortadas sujetandolas desde arriba y desde abajo.The cut preforms are transported through the individual stations by driven transport means. As driven transport means two or three pairs of transport belts are used that are arranged at a certain transverse distance so that they carry the cut preforms holding them from above and below.
Es conocido disponer en la estacion de transferencia un dispositivo de descarga para expulsar cajas detectadas como defectuosas antes de que se produzca la corriente imbricada de cajas al principio del dispositivo de recogida y prensado. Por medio de la estacion de transferencia se transportan las cajas todavfa individualmente y a distancia una de otra, de modo que pueda retirarse de la maquina una caja individual. Las cajas defectuosas son, por ejemplo, cajas que no estan suficientemente encoladas, cajas que tienen defectos de plegado o cajas que, en un control de identidad, no se reconocen como pertenecientes al pedido. Como elementos de transporte, la estacion de transferencia presenta por lo menos dos paredes de correas de transporte que consisten en una correa superior y una correa inferior.It is known to have a discharge device in the transfer station to eject boxes detected as defective before the imbricated stream of boxes is produced at the beginning of the collection and pressing device. The boxes are still transported individually and remotely from each other via the transfer station, so that an individual box can be removed from the machine. Defective boxes are, for example, boxes that are not sufficiently glued, boxes that have folding defects or boxes that, in an identity check, are not recognized as belonging to the order. As transport elements, the transfer station has at least two walls of transport belts consisting of an upper belt and a lower belt.
Para retirar preformas cortadas de cajas plegables o cajas plegables defectuosas de la corriente de transporte, se conocen por el estado de la tecnica, aparte de dispositivos de descarga externos, como eyectores de plato y lineales, dispositivos de descarga externos.To remove cut preforms from folding boxes or defective folding boxes from the transport stream, they are known by the state of the art, apart from external discharge devices, such as plate and linear ejectors, external discharge devices.
Los eyectores de plato y lineales son dispositivos que estan dispuestos por fuera junto a un par de correas que sirven como elementos de transporte en la estacion de transferencia. Estos atacan en una parte de caja que sobresale por fuera de las correas para extraer hacia un lado la caja defectuosa de entre el par de correas de transporte. Tales eyectores de plato y lineales se describen como conocidos en el documento dE 10 2004 022 211 A1. Ademas, se propone un recorrido especialmente configurado de correas de transporte para retirar cajas defectuosas de la maquina de pegado de cajas plegables de una manera mas sencilla.The plate and linear ejectors are devices that are arranged on the outside next to a pair of belts that serve as transport elements in the transfer station. These attack in a box part that protrudes outside the belts to remove the defective box from the pair of transport belts. Such plate and linear ejectors are described as known in document 10 2004 022 211 A1. In addition, a specially configured route of transport belts is proposed to remove defective boxes from the folding box gluing machine in a simpler way.
En cambio, en los dispositivos de descarga internos la trayectoria de transporte es interrumpida por un dispositivo de aguja de desvfo. Gracias a unos medios de desviacion, la trayectoria de transporte puede desviarse hacia arriba o hacia abajo, de modo que se expulsen las preformas cortadas de caja desviadas. Tal dispositivo de descarga interno es conocido, por ejemplo, por el documento DE 698 16 717 T2. En estos dispositivos de descarga internos conocidos es desventajoso que la maxima velocidad de expulsion posible, debido a las condiciones ffsicas, este por debajo de la maxima cantidad de preformas cortadas a procesar por unidad de tiempo.On the other hand, in the internal discharge devices the transport path is interrupted by a deflection needle device. Thanks to deflection means, the transport path can be diverted upwards or downwards, so that the cut preforms of the deviated box are ejected. Such an internal discharge device is known, for example, from DE 698 16 717 T2. In these known internal discharge devices it is disadvantageous that the maximum possible expulsion speed, due to physical conditions, is below the maximum amount of cut preforms to be processed per unit of time.
Para los dispositivos de descarga externos se conocen, segun se ha mencionado, como dispositivos para extraer las cajas unos denominados eyectores de plato giratorio que contienen un plato giratorio, accionado con un elevado numero de revoluciones y que llega hasta debajo de las partes de caja sobresalientes, y unos elementos de apriete dispuestos sobre el mismo. En presencia de una caja defectuosa, esta se aprieta fuertemente con los elementos de apriete sobre el plato giratorio y se la extrae de la maquina por efecto del giro. Un dispositivo de este tipo se describe en el documento DE 102 24 814 A1. Los eyectores de plato giratorio son de funcionamiento seguro y requieren un pequeno coste de construccion, pero solo son adecuados para cajas de un tamano pequeno a medio.For external discharge devices, they are known, as mentioned, as devices for extracting the boxes called turntable ejectors containing a turntable, driven with a high number of revolutions and reaching below the protruding case parts , and some clamping elements arranged thereon. In the presence of a defective box, it is pressed tightly with the clamping elements on the turntable and is removed from the machine due to the rotation. Such a device is described in DE 102 24 814 A1. The turntable ejectors are safe to operate and require a small construction cost, but are only suitable for small to medium sized boxes.
Las cajas mas grandes se expulsan por los denominados eyectores lineales, como los que se describen en el documento EP 0 557 609 A1. Estos contienen transportadores de banda entre los cuales se aprisionan las cajas y se las retira de la maquina en lfnea recta. Los eyectores lineales requieren un elevado coste de construccion.Larger boxes are ejected by the so-called linear ejectors, such as those described in EP 0 557 609 A1. These contain belt conveyors between which the boxes are trapped and removed from the machine in a straight line. Linear ejectors require a high construction cost.

Tanto con eyectores de plato como tambien con eyectores lineales no es posible una expulsion fiable de cajas de fondo plegado, cajas de 4 puntos, cajas de 6 puntos o cajas con geometnas complicadas. Para estas clases de caja es conveniente utilizar dispositivos de descarga internos.Reliable ejection of folded bottom boxes, 4-point boxes, 6-point boxes or boxes with complicated geometries is not possible with both plate ejectors or linear ejectors. For these cash types it is convenient to use internal discharge devices.
El problema de la presente invencion es crear una maquina de pegado de cajas plegables con la que puedan expulsarse de manera segura preformas cortadas defectuosas aprovechando la velocidad optima de la maquina.The problem of the present invention is to create a machine for gluing folding boxes with which defective cut preforms can be safely ejected taking advantage of the optimum speed of the machine.
Este problema se resuelve por medio de una maquina de pegado de cajas plegables con las caractensticas de la parte caracterizante de la reivindicacion 1.This problem is solved by means of a machine for gluing folding boxes with the characteristics of the characterizing part of claim 1.
La maquina de pegado de cajas plegables, ademas de un dispositivo de descarga interno, por lo menos otro dispositivo de descarga externo. Los respectivos dispositivos de descarga se pueden controlar en funcion del tipo de caja y/o de la velocidad de funcionamiento deseada para expulsar preformas cortadas de caja defectuosas.The machine for gluing folding boxes, in addition to an internal unloading device, at least one other external unloading device. The respective unloading devices can be controlled according to the type of box and / or the desired operating speed to eject defective preforms cut out of the box.
Con este dispositivo es luego posible utilizar las ventajas ya expuestas de los dispositivos de descarga individuales y, ademas, combinar las ventajas.With this device it is then possible to use the advantages already mentioned of the individual download devices and, in addition, to combine the advantages.
En una forma de realizacion especialmente preferida, los dispositivos de descarga estan equipados con accionamientos individuales independientes. Esto hace posible configurar los diferentes dispositivos de descarga como modulos para construir asf de forma optima y flexible la maquina de pegado de cajas plegables.In a particularly preferred embodiment, the discharge devices are equipped with independent individual drives. This makes it possible to configure the different unloading devices as modules to optimally and flexibly build the folding box gluing machine.
A continuacion, se explica con detalle la invencion con ayuda de los ejemplos de formas de realizacion representados en los dibujos, en los que:Next, the invention is explained in detail with the help of the examples of embodiments represented in the drawings, in which:
La figura 1 es una vista lateral esquematica de estaciones individuales de una maquina de pegado de cajas plegables,Figure 1 is a schematic side view of individual stations of a folding box gluing machine,
Las figuras 2a, 2b es una representacion esquematica de un eyector lineal conocido; yFigures 2a, 2b is a schematic representation of a known linear ejector; Y
La figura 3 es una representacion esquematica de un eyector de plato conocido.Figure 3 is a schematic representation of a known plate ejector.
La figura 1 muestra a modo de ejemplo las estaciones de una maquina de pegado de cajas plegables. En la direccion de transporte (de izquierda a derecha), esta maquina comienza con un alimentador 1 que retira sucesivamente de una pila con alta velocidad las preformas cortadas a procesar y las suministra individualmente a las siguientes estaciones de tratamiento. Al alimentador 1 le sigue un premachacador 2 que, en el presente ejemplo de realizacion, esta configurado en dos etapas. El premachacador 2 contiene unos elementos de plegado para plegar hacia delante y hacia atras unas solapas plegables para que las correspondientes lmeas de estriado longitudinales se vuelvan blandas y ductiles.Figure 1 shows by way of example the stations of a folding box gluing machine. In the transport direction (from left to right), this machine starts with a feeder 1 that successively removes the preforms cut to be processed from a high-speed stack and supplies them individually to the following treatment stations. The feeder 1 is followed by a pre-puncher 2 which, in the present embodiment, is configured in two stages. The pre-crusher 2 contains folding elements to fold forward and backward folding flaps so that the corresponding longitudinal striated lines become soft and ductile.
Al premachacador 2 le sigue como estacion de tratamiento mas proxima una estacion de plegado 3 al principio de la cual esta dispuesto un mecanismo de aplicacion 4 para material adhesivo, usualmente cola. El mecanismo 4 de aplicacion de adhesivo contiene toberas de cola o discos de cola por los que se aplica el material adhesivo en forma de tiras sobre las preformas cortadas. Antes de que las solapas plegables provistas de tiras adhesivas se plieguen por los elementos de plegado de la estacion de plegado 3, se realiza un control de la tira adhesiva aplicada. Para ello, la tira adhesiva se explora sin contacto con un denominado aparato de control de costuras de cola. En caso de que la tira adhesiva no presente la calidad requerida, se notifica la caja como defectuosa a la unidad de control central. Al final de la estacion de plegado 3 se comprueban las cajas plegables en busca de defectos de plegado. Para ello, estan dispuestas en esta zona unas fotocelulas por las que se explora la longitud de la caja. Si la longitud no corresponde al formato prefijado, por ejemplo porque una solapa no se haya doblado correctamente, entonces se notifica tambien esta caja como defectuosa a la unidad de control central.The pre-puncher 2 is followed by a folding station 3 as the nearest treatment station at the beginning of which an application mechanism 4 for adhesive material, usually glue, is arranged. The adhesive application mechanism 4 contains glue nozzles or glue discs by which the adhesive material in the form of strips is applied over the cut preforms. Before the folding flaps provided with adhesive strips are folded by the folding elements of the folding station 3, a control of the applied adhesive strip is carried out. For this, the adhesive strip is scanned without contact with a so-called glue sewing control apparatus. If the adhesive strip does not have the required quality, the box is notified as defective to the central control unit. At the end of the folding station 3, the folding boxes are checked for folding defects. For this, photocells are arranged in this area through which the length of the box is explored. If the length does not correspond to the default format, for example because a flap has not been folded correctly, then this box is also notified as defective to the central control unit.
La estacion de plegado 3 va seguida por un dispositivo de descarga interno 7. Por medio de este, las preformas cortadas de caja defectuosas se expulsan de manera conocida a traves de una aguja de desvfo controlada, por ejemplo hacia abajo hasta un recipiente 8.The folding station 3 is followed by an internal discharge device 7. By means of this, the defective preforms cut out of the case are known to be ejected in a known manner through a controlled deflection needle, for example downwards to a container 8.
El dispositivo de descarga interno 7 va seguido por un dispositivo de transferencia 5. Este tiene la mision primaria de suministrar las cajas plegables plegadas, provistas de costuras adhesivas aun no fraguadas con todas sus partes orientadas, a un siguiente dispositivo de recogida y prensado 6. Durante el paso de la estacion de transferencia 5 al dispositivo de recogida y prensado 6 se produce una corriente imbricada constituida por las cajas plegadas. El dispositivo de recogida y prensado 6 presenta unas bandas de prensado por medio de las cuales se mantienen a presion las costuras adhesivas durante el transporte hasta que el material adhesivo haya fraguado de manera segura.The internal unloading device 7 is followed by a transfer device 5. This has the primary mission of supplying the folded folding boxes, provided with adhesive seams not yet set with all their parts oriented, to a following collection and pressing device 6. During the passage of the transfer station 5 to the collection and pressing device 6, an imbricated current consisting of the folded boxes is produced. The collecting and pressing device 6 has pressing bands by means of which the adhesive seams are held under pressure during transport until the adhesive material has set securely.
En la estacion de transferencia 5 esta dispuesto adicionalmente un dispositivo de descarga que contiene un dispositivo dispuesto por fuera junto al par de correas de transporte 9, 9' o 10, 10' (figura 2a) y destinado a realizarIn the transfer station 5, an unloading device is additionally provided that contains a device arranged on the outside next to the pair of transport belts 9, 9 'or 10, 10' (figure 2a) and intended to be

una extraccion lateral de cajas defectuosas 12'. El dispositivo para extraer las cajas 12' es preferentemente un eyector de plato giratorio o un eyector lineal, como estos se describen en la introduccion de la descripcion y en las citas bibliograficas allf presentadas. El eyector ataca las cajas 12 en una parte 22 sobresaliente hacia fuera de las correas de transporte 9, 9' o 10, 10' y las extrae de la maquina.a side extraction of defective boxes 12 '. The device for extracting the boxes 12 'is preferably a turntable ejector or a linear ejector, as these are described in the introduction of the description and in the references cited theref. The ejector attacks the boxes 12 in an protruding part 22 out of the transport belts 9, 9 'or 10, 10' and removes them from the machine.
En las figuras 2a y 2b esta representado a modo de ejemplo un eyector lineal conocido. Como se ve en la figura 2a, dos respectivas bandas transportadoras sin fin 9, 9' y 10, 10' estrechamente superpuestas una a otra (de las que solo esta representada la respectiva banda superior) aprisionan las preformas cortadas de caja 12 entre ellas y forman asf un trayecto de transporte 11. Las preformas cortadas de caja se mueven con una velocidad V1 en la direccion de la flecha. Lateralmente formando un angulo a con el trayecto de transporte 11 esta representado un dispositivo eyector 13 en forma de un eyector lineal. Como se puede ver en la figura 2b, el eyector lineal consta de una banda de transporte 18, que es guiada alrededor de dos rodillos 17 y 19, y una superficie 15 de poca friccion. El rodillo 17 se acciona por medio de un motor no representado. Entre la banda de transporte 18 y la superficie 15 se aprisionan y se expulsan las preformas cortadas de caja defectuosas. Para ello, puede servir como pinza, por ejemplo, una seccion pivotable 16 de la banda de transporte, para lo cual se gufa esta alrededor de un rodillo abatible 19.In figures 2a and 2b, a known linear ejector is shown by way of example. As seen in Figure 2a, two respective endless conveyor belts 9, 9 'and 10, 10' closely superimposed on each other (of which only the respective upper band is represented) imprison the cut-out preforms of box 12 between them and thus they form a transport path 11. The cut-out box preforms move with a velocity V1 in the direction of the arrow. Laterally forming an angle a with the transport path 11 is an ejector device 13 in the form of a linear ejector. As can be seen in Figure 2b, the linear ejector consists of a conveyor belt 18, which is guided around two rollers 17 and 19, and a low friction surface 15. The roller 17 is driven by a motor not shown. Between the conveyor belt 18 and the surface 15 they are trapped and the defective preforms cut out of the box are ejected. For this, it can serve as a clamp, for example, a pivotable section 16 of the conveyor belt, for which it is guided around a collapsible roller 19.
La velocidad de expulsion V2 es mas elevada que la velocidad de transporte V1. Esto se materializa por que se eligeThe ejection speed V2 is higher than the transport speed V1. This materializes because it is chosen

La figura 3 muestra a modo de ejemplo un eyector de plato conocido. El eyector de plato 30, al igual que el eyector lineal 13 representado en la figura 2a, esta dispuesto tambien lateralmente con respecto al trayecto de transporte 11, de modo que puede detectar las secciones sobresalientes 22 de las cajas 12 para expulsar asf las cajas defectuosas 12'.Figure 3 shows by way of example a known plate ejector. The plate ejector 30, like the linear ejector 13 shown in Figure 2a, is also arranged laterally with respect to the transport path 11, so that it can detect the protruding sections 22 of the boxes 12 so as to eject the defective boxes 12 '.
El eyector de plato 30 contiene un plato giratorio plano 31 que gira permanentemente con alta velocidad, que se acciona por un motor electrico 32 y que esta dispuesto inmediatamente por fuera junto a los pares de correas de transporte 9, 9' o 10, 10'. El plato giratorio 31 del eyector 30 esta fabricado en este caso de metal o plastico. No obstante, puede ser tambien de metal y llevar un recubrimiento de plastico. Asimismo, es imaginable aplicar un revestimiento sobre un disco metalico, tal como, por ejemplo, una aleacion que contenga molibdeno.The plate ejector 30 contains a flat turntable 31 which rotates permanently with high speed, which is driven by an electric motor 32 and which is arranged immediately outside with the pairs of transport belts 9, 9 'or 10, 10' . The turntable 31 of the ejector 30 is made in this case of metal or plastic. However, it can also be metal and have a plastic coating. It is also imaginable to apply a coating on a metal disk, such as, for example, an alloy containing molybdenum.
Asimismo, el eyector de plato 30 contiene por lo menos dos discos de presionado 33, 34 que estan dispuestos uno detras de otro, en la direccion de transporte 11, detras del centro y en el borde exterior del plato giratorio 31. El angulo entre los discos de presionado 33, 34 y los pares de correas de transporte 9, 9' o 10, 10' es ajustable por medio de una articulacion giratoria 35 en el dispositivo de retencion de los discos de presionado 33, 34. El primer disco de presionado 33 en la direccion de transporte esta orientado hacia fuera con una inclinacion en angulo agudo con respecto a la direccion de transporte de los pares de correas 9, 9' o 10, 10'. El segundo disco de presionado 34 en la direccion de transporte esta ajustado preferentemente segun un angulo de mas de 45 grados con respecto a la direccion de transporte de los pares de correas 9, 9' o 10, 10'. Los discos de presionado 33, 34 estan montados de manera libremente giratoria y movil. En este caso, la distancia entre el plato giratorio 31 y los discos de presionado 33, 34 puede ajustarse por medio de una palanca en angulo 36 y un tornillo de reglaje correspondiente 37, no descansando los discos de presionado 33, 34 sobre el plato giratorio 31. La palanca 39 de dos lados se mantiene paralela sobre el disco giratorio 31 por medio de un tope 38 para alojar los discos de presionado 33, 34 montados de manera libremente giratoria. La contrapresion necesaria para el tope 39 se generar por medio de un elemento de resorte 40.Also, the plate ejector 30 contains at least two pressing discs 33, 34 that are arranged one behind the other, in the transport direction 11, behind the center and on the outer edge of the turntable 31. The angle between the pressing discs 33, 34 and the pairs of transport belts 9, 9 'or 10, 10' is adjustable by means of a swivel joint 35 in the retaining device of the pressing discs 33, 34. The first pressing disc 33 in the direction of transport is oriented outward with an acute angle inclination with respect to the direction of transport of the pairs of belts 9, 9 'or 10, 10'. The second pressing disc 34 in the transport direction is preferably adjusted according to an angle of more than 45 degrees with respect to the transport direction of the pairs of belts 9, 9 'or 10, 10'. The pressing discs 33, 34 are mounted in a freely rotating and movable manner. In this case, the distance between the turntable 31 and the pressing discs 33, 34 can be adjusted by means of an angle lever 36 and a corresponding adjustment screw 37, the pressure discs 33, 34 not resting on the turntable 31. The two-sided lever 39 is held parallel on the rotating disk 31 by means of a stop 38 to accommodate the pressure discs 33, 34 mounted in a freely rotatable manner. The necessary back pressure for the stop 39 will be generated by means of a spring element 40.
El control de los correspondientes dispositivos de descarga se realiza por medio de un dispositivo de control 41 no representado con detalle.The control of the corresponding discharge devices is carried out by means of a control device 41 not shown in detail.
