Description

Maquina para pegar cajas plegables con accesibilidad mejorada Machine for gluing folding boxes with improved accessibility

El invento se refiere a una maquina para pegar cajas plegables para el manejo de recortes de cajas plegables, compuesta como minimo de un introductor para equipar una siguiente estaci6n de mecanizado, una estaci6n de The invention relates to a machine for gluing folding boxes for the handling of cutouts of folding boxes, composed of at least one introducer to equip a next machining station, a station of

5 plegado, un equipo de aplicaci6n para un material adhesivo, una estaci6n de transferencia especialmente con un dispositivo de salida, un dispositivo de agrupaci6n y prensado con un dispositivo de seguridad para una parte de maquina peligrosa para un usuario. 5 folding, an application equipment for an adhesive material, a transfer station especially with an exit device, a grouping and pressing device with a safety device for a dangerous machine part for a user.

Las maquinas para pegar cajas plegables del tipo acorde con el genero para la fabricaci6n de cajas plegables a partir de recortes de cajas plegables presentan de manera conocida los siguientes m6dulos como estaciones de The machines for gluing folding boxes of the type according to the genre for the manufacture of folding boxes from cut-out of folding boxes present the following modules in known manner as stations of

10 manejo: 10 handling:

un introductor que extrae de una pila uno tras otro con alta velocidad los recortes que van a ser manejados y los guia individualmente a la siguiente primera estaci6n de manejo.   an introducer that removes the cuts that are to be handled from one pile after the other with high speed and guides them individually to the next first driving station.

un equipo de aplicaci6n de materiales adhesivos, habitualmente cola, que aplica una raya de adhesivo sobre los recortes que van a ser pegados y   an adhesive material application equipment, usually glue, which applies a strip of adhesive on the cutouts to be glued and

15 una estaci6n de plegado en la que los recortes provistos con una raya de adhesivo son girados 1800 y tambien plegados. 15 a folding station in which the cuts provided with a strip of adhesive are turned 1800 and also folded.

En conexi6n con la estaci6n de plegado esta situada habitualmente una asi llamada estaci6n de transferencia en la que las cajas pueden ser contadas, marcadas y sacadas. Despues sigue una estaci6n de agrupaci6n y prensado en cuyo comienzo se forma una corriente de escamas con recortes plegados que es mantenida durante algun tiempo In connection with the folding station a so-called transfer station is usually located in which the boxes can be counted, marked and taken out. Then follows a grouping and pressing station at the beginning of which a stream of flakes with folded cuts is formed that is maintained for some time.

20 bajo presi6n en la estaci6n de prensado, para que ambas partes del recorte se unan en el cord6n de adhesivo. 20 under pressure in the pressing station, so that both parts of the cutout are joined in the adhesive cord.

Para poder hacer pliegues transversalmente a la direcci6n de transporte de los recortes de cajas plegables, en la maquina de pegar cajas plegables se montan dispositivos adicionales. Tales dispositivos son conocidos por ejemplo, por el documento americano US 4.118.018. Se utilizan para la fabricaci6n de las cajas plegables con o sin anexos triangulares, como es habitual en las cajas de 4 puntos, cajas de 6 puntos, cajas de fondo plegables o cajas 25 especiales. En un dispositivo de este tipo conocido las herramientas de plegar a posteriori se componen de ganchos apoyados por debajo del plano de transporte que con sus extremos libres acodados agarran por debajo el nervio pr6ximo situado plano, y durante el siguiente transporte del recorte lo adelantan de manera que el nervio es plegado hacia abajo y llega a quedar plano sobre el recorte de la caja plegable. Una herramienta como esta es llamada tambien gancho de centrar el recorte. Con el fin de que la instalaci6n quede asegurada frente al usuario, una 30 herramienta de este tipo que durante el funcionamiento de la maquina de pegar cajas plegables se mueve muy rapido, puede ser cerrada esa zona con una protecci6n de acceso, por ejemplo en forma de una puerta de seguridad. Pero este tipo de medidas de seguridad limitan innecesariamente la accesibilidad de la maquina de pegar cajas plegables, especialmente durante el manejo de los recortes que deben ser manejados sin el empleo de ganchos de centrar el recorte. Otra maquina de pegar cajas plegables acorde con el genero es conocida por la In order to make folds transversely to the direction of transport of the folding box cutouts, additional devices are mounted on the folding machine. Such devices are known, for example, from US 4,118,018. They are used for the manufacture of folding boxes with or without triangular attachments, as usual in 4-point boxes, 6-point boxes, folding bottom boxes or special boxes. In a device of this type known the posterior folding tools are made up of hooks supported below the transport plane which with their angled free ends grasp the proximal rib located flat below, and during the next transport of the cut they advance it in a manner that the nerve is folded down and becomes flat on the cutout of the folding box. A tool like this is also called the centering clip. In order for the installation to be secured in front of the user, a tool of this type that during the operation of the machine for gluing folding boxes moves very fast, that area can be closed with an access protection, for example in shape of a security door. But this type of security measures unnecessarily limit the accessibility of the machine to glue folding boxes, especially during the handling of the cuts that must be handled without the use of hooks to center the cut. Another machine to glue folding boxes according to the genre is known by the

35 publicaci6n DE-A-199480117. 35 publication DE-A-199480117.

Es por tanto misi6n del invento el desarrollar una maquina de pegar cajas plegables para el manejo de recortes de cajas plegables que se corresponda con las directrices de seguridad, que ademas puede ser adaptada a los mas diferentes recortes de cajas plegables y a los riesgos resultantes de ello y que adicionalmente perjudique solo de manera minima a la accesibilidad de la maquina de pegar cajas plegables. It is therefore the mission of the invention to develop a machine for gluing folding boxes for handling folding box cutouts that corresponds to the safety guidelines, which can also be adapted to the most different folding box cuttings and the risks resulting therefrom. and that additionally only minimally damage the accessibility of the machine to glue folding boxes.

40 Esta misi6n sera resuelta de acuerdo con el invento por una maquina de pegar cajas plegables con las caracteristicas de la reivindicaci6n 1. 40 This mission will be solved in accordance with the invention by a machine for gluing folding boxes with the characteristics of claim 1.

Mediante la utilizaci6n acorde con el invento de una cortina de luz en combinaci6n con un servomotor y la integraci6n y/o el montaje de la cortina de luz en partes de maquina existentes se crea ahora la posibilidad de utilizar una maquina de pegar cajas plegables sin perjudicar la accesibilidad de la instalaci6n y ademas poder ajustar 45 individualmente la zonas de partes de la maquina que van a ser vigiladas. Mediante la utilizaci6n acorde con el invento de una cortina de luz en combinaci6n con accionamientos motorizados para los distintos puntos de peligro de la maquina se puede conseguir, incluso en el caso de las velocidades mas altas de fabricaci6n, un tiempo de frenado en las partes de maquina que ponen en riesgo al usuario que cumpla con las directivas de protecci6n de seguridad. Si por ejemplo, las partes de maquina que ponen en riesgo al usuario, por ejemplo los ganchos de centrar By using according to the invention of a light curtain in combination with a servo motor and the integration and / or assembly of the light curtain in existing machine parts, the possibility of using a folding glue machine without damaging boxes is now created. the accessibility of the installation and also to be able to individually adjust the areas of parts of the machine to be monitored. By using in accordance with the invention a light curtain in combination with motorized drives for the various danger points of the machine, a braking time can be achieved even in the case of higher manufacturing speeds. machine that puts at risk the user who complies with the safety protection directives. If for example, the machine parts that put the user at risk, for example the centering hooks

50 el recorte antes mencionados, no se utilizan entonces se puede desactivar la cortina de luz y el usuario puede disponer entonces de libre acceso a las correspondientes partes de maquina. Por ello una utilizaci6n del dispositivo de seguridad no esta unido a una modificaci6n mecanica de la maquina de pegar cajas plegables 50 the aforementioned trimming, they are not used then the light curtain can be deactivated and the user can then have free access to the corresponding machine parts. Therefore, a use of the safety device is not linked to a mechanical modification of the machine for gluing folding boxes.

A continuaci6n se explicara el invento sobre la base de un ejemplo constructivo y unas figuras. Se muestra: Next, the invention will be explained on the basis of a constructive example and figures. It shows:

Figura 1 la vista lateral y la vista en planta superior de la maquina de pegar cajas plegables, Figure 1 the side view and the top plan view of the machine for gluing folding boxes,

Figura 2 la vista isometrica sobre una parte de la instalaci6n de plegado de la maquina de pegar cajas plegables, acorde con la Figura 1 y Figure 2 isometric view on a part of the folding installation of the machine for gluing folding boxes, in accordance with Figure 1 and

Figura 3 la vista lateral de una maquina de pegar cajas plegables a escala ampliada. Figure 3 the side view of a machine for gluing folding boxes on an enlarged scale.

En la figura 1 estan representadas la vista lateral y la vista en planta superior de una maquina de pegar hojas. La maquina de pegar cajas plegables 1 comprende como estaci6n de manejo un introductor 2, una estaci6n de plegado 3, una estaci6n de transferencia 4 y un dispositivo 5 para agrupamiento. Estas estaciones de trabajo contienen medios de transporte para las cajitas que son accionados mediante accionamientos motorizados. Figure 1 shows the side view and the top plan view of a sheet glue machine. The folding box gluing machine 1 comprises as driving station an introducer 2, a folding station 3, a transfer station 4 and a device 5 for grouping. These workstations contain means of transport for the boxes that are driven by motorized drives.

En la estaci6n de plegado 3 puede ser utilizado un gancho de centrar el recorte mediante el que podria provocarse un riesgo para el usuario en el manejo de la maquina de pegar cajas plegables. En el caso de una parte de maquina de este tipo que cause riesgo al usuario de la instalaci6n esta parte de la maquina debe ser protegida contra un acceso. Un mecanismo de enclavamiento entre ambos estatores 6,7 de la estaci6n de plegado 3 actua de manera desventajosa por ejemplo sobre los tiempos de instalaci6n de la maquina. Pero una utilizaci6n de acorde con el invento de una cortina de luz, que esta integrada en la maquina, no tiene ninguna influencia en la accesibilidad de las diferentes partes de la maquina individualmente. Especialmente porque los estatores 6,7 sirven simultaneamente como soporte para por ejemplo el interruptor de emergencia 8. Como se aprecia en la vista en planta, los estatores 6,6' y 7,7' estan situados a ambos lados de la estaci6n de plegado 3. Asi, especialmente por ejemplo, un emisor de la cortina de luz puede estar situado en el estator 6 y el correspondiente receptor en el estator 7. Lo mismo sirve para los estatores 6',7'. In the folding station 3 a hook can be used to center the cut-out by means of which a risk could be caused for the user in the handling of the machine for gluing folding boxes. In the case of such a machine part that causes a risk to the user of the installation, this part of the machine must be protected against access. An interlocking mechanism between both stators 6.7 of the folding station 3 acts disadvantageously, for example, on the installation times of the machine. But a use according to the invention of a light curtain, which is integrated in the machine, has no influence on the accessibility of the different parts of the machine individually. Especially because the stators 6,7 simultaneously serve as a support for for example the emergency switch 8. As can be seen in the plan view, the stators 6,6 'and 7,7' are located on both sides of the folding station 3. Thus, especially for example, a light curtain emitter may be located in the stator 6 and the corresponding receiver in the stator 7. The same applies to the stators 6 ', 7'.

Lo demas se describe en la figura 3. Los estatores 6,6' y 7,7' que son parte componente de soporte de la maquina 1 de pegar cajas plegables estan construidas de tal manera que los elementos para la cortina de luz pueden estar sujetos a ellos y porque ellos pueden simultaneamente atravesar las cortinas de luz 9,10,11,12. Para ello en las envolvente de chapa que envuelven los estatores han sido practicadas ranuras alargadas 13,14 a traves de las que el emisor de la cortina de luz 9,10,11,12 pueden trabajar junto con su correspondiente emisor 9,10,11,12. En la figura 2 esta reproducida una vista tridimensional correspondiente de las cortinas de luz 9,10,11,12 en la estaci6n de plegado 3. En la figura 2 tambien estan dibujados los accionamientos 15,16 del gancho 17 de centrar el recorte, que estan disenados como accionamientos electromotorizado. Los accionamientos electromotorizados 15,16 estan conectados directamente al eje sobre el que estan sujetos los ganchos 17 de centrar el recorte. The rest is described in Figure 3. The 6,6 'and 7,7' stators that are component support part of the machine 1 for gluing folding boxes are constructed in such a way that the elements for the light curtain can be attached to them and because they can simultaneously pass through the light curtains 9,10,11,12. For this, in the sheet metal envelopes that surround the stators, elongated grooves 13,14 have been made through which the light curtain emitter 9,10,11,12 can work together with its corresponding emitter 9,10,11 , 12. In figure 2 a corresponding three-dimensional view of the light curtains 9,10,11,12 in the folding station 3 is reproduced. In figure 2 the drives 15,16 of the hook 17 of centering the cutout are also drawn, which They are designed as electromotorized drives. The electromotorized drives 15,16 are connected directly to the axis on which the hooks 17 of centering the cutout are attached.

En la figura 3 esta representada en la vista lateral una maquina de pegar cajas plegables 18 ampliada con otras estaciones de trabajo y construida de forma modular. La palabra construida de forma modular vale aqui por una posibilidad de ordenaci6n a voluntad de las estaciones de trabajo. La maquina de pegar cajas plegables 18 posee varias estaciones de trabajo con uno o varios estatores 19. Ahora, y segun el riesgo para el usuario, una zona individual de la maquina 18 que hay que aprovisionar puede ser asegurada mediante una cortina de luz. Asi, por ejemplo, se puede pensar en situar la cortina de luz entre los estatores 19 y 20 o entre los estatores 19 y 21 o entre los estatores 19 y 22 o en los estatores 20 y 22 o en cualquier combinaci6n deseada de los estatores 19,20,21,22. In figure 3 a machine for gluing folding boxes 18 enlarged with other workstations and constructed in a modular manner is shown in the side view. The word constructed in a modular way is valid here for a possibility of ordering at the will of the work stations. The folding box gluing machine 18 has several work stations with one or more stators 19. Now, and according to the risk to the user, an individual area of the machine 18 to be provisioned can be secured by a light curtain. Thus, for example, it is possible to consider placing the light curtain between the stators 19 and 20 or between the stators 19 and 21 or between the stators 19 and 22 or on the stators 20 and 22 or on any desired combination of the stators 19 , 20,21,22.

Se prefiere que la cortina de luz 9,10,11,12 pueda ser activada dependiendo de la activaci6n de las partes de maquina peligrosas, por ejemplo el gancho 17 de centrar el recorte. Si no se esta utilizando ninguna parte de maquina peligrosa se desactiva la cortina de luz 9,10,11,12 para que la maquina pueda ser mas accesible por parte de la persona de servicio. It is preferred that the light curtain 9,10,11,12 can be activated depending on the activation of the dangerous machine parts, for example the hook 17 to center the cutout. If no part of the dangerous machine is being used, the light curtain 9,10,11,12 is deactivated so that the machine can be more accessible by the service person.

Como se desprende igualmente de la figura 2 puede ocurrir que el gancho 17 de centrar el recorte este situado demasiado lejos de los bordes laterales de la estaci6n de plegado 3. Para poder detener la maquina de pegar cajas plegables y sus accionamientos 15,16 en el correspondiente corto tiempo despues de la entrada de la persona de servicio en la cortina de luz 9,10,11,12 puede ser necesario situar las cortinas de luz 11,12 sobresalientes lateralmente. En la figura 2 esta representado un correspondiente desplazamiento de las cortinas de luz 11,12. La zona inferior de la cortina de luz 11,12 vas mas alla lateralmente de la instalaci6n que la zona superior. Esto puede ser tambien necesario si por ejemplo como esta representado en la figura 2, los servomotores 15,16 impiden un trabajo sin impedimentos de la cortina de luz 11,12 As can also be seen from Figure 2, it can happen that the hook 17 for centering the cutout is located too far from the side edges of the folding station 3. In order to stop the machine from gluing folding boxes and their drives 15,16 on the corresponding short time after the entry of the service person in the light curtain 9,10,11,12 it may be necessary to place the light curtains 11,12 protruding laterally. A corresponding displacement of the light curtains 11,12 is shown in Figure 2. The lower zone of the light curtain 11,12 goes beyond the installation sideways than the upper zone. This may also be necessary if, for example, as shown in Figure 2, servo motors 15,16 prevent unhindered work of the light curtain 11,12

Asi la cortina de luz 11,12 puede estar tambien situada por fuera de las partes de maquina que forman la estaci6n de plegado. Thus the light curtain 11,12 can also be located outside the machine parts that form the folding station.

Si la maquina esta preparada para el servicio o en producci6n y un usuario se acerca a la cortina de luz 9,10,11,12 de manera que podria alcanzar la zona peligrosa, entonces en el caso de una interrupci6n de la cortina de luz 9,10,11,12 la maquina se detiene y frena en el tiempo mas corto. O ahora los propios ganchos de adelantamiento se detienen, preferiblemente en 0,10 segundos, o adicionalmente los accionamientos servomotorizados de transporte detienen la maquina de pegar cajas plegables 1, de manera que dentro de ese tiempo mas corto queda totalmente frenada, por ejemplo en el plazo de 0,25 segundos, desde una velocidad de transporte de cajas plegables desde 300 m/min. a 0 m/min. En ese tiempo al usuario no le es posible desde la zona de fuera de la cortina de luz 9,10,11,12 alcanzar la zona peligrosa, por ejemplo el gancho 17 de centrar el recorte. La maquina de pegar cajas plegables se corresponde con esto igualmente a las prescripciones de seguridad validas para las directrices. If the machine is ready for service or in production and a user approaches the light curtain 9,10,11,12 so that it could reach the danger zone, then in the case of a light curtain interruption 9 , 10,11,12 the machine stops and brakes in the shortest time. Or now the overtaking hooks themselves stop, preferably in 0.10 seconds, or additionally the servomotorized transport drives stop the machine from gluing folding boxes 1, so that within that shortest time it is fully braked, for example in the 0.25 seconds, from a transport speed of folding boxes from 300 m / min. at 0 m / min. At that time it is not possible for the user from the area outside the light curtain 9,10,11,12 to reach the dangerous zone, for example the hook 17 to center the cutout. The machine for gluing folding boxes also corresponds to the safety requirements valid for the guidelines.
