Abstract
Description
Dispositivo para plegar partes de cajas de cartón.Device for folding parts of cardboard boxes.
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo para plegar partes de cajas de cartón que consiste en crear un movimiento descendente al mismo tiempo que gira un brazo para llevar a cabo el plegado de partes correspondientes de cajas de cartón.The present invention, as expressed in the statement of this Descriptive memory, refers to a device for folding parts of cardboard boxes consisting of creating a downward movement while turning an arm to carry out the folding of Corresponding parts of cardboard boxes.
De esta forma conseguimos que el punto de empuje al final del abatimiento de las partes o solapas a abatir esté centrado, con lo cual la presión sobre dichas solapas estará totalmente equilibrada.In this way we get the push point at the end of the dejection of the parts or flaps to be lowered is centered, so which pressure on these flaps will be totally balanced
En la actualidad existen dispositivos para plegar partes de cajas de cartón que incluyen básicamente un elemento giratorio que en su movimiento arrastran a la parte de cartón a abatir, tales como solapas que forman parte de columnas triangulares de refuerzo, de manera que al final de su abatimiento estas solapas hacen tope contra las caras internas de las paredes laterales para unirse a ellas mediante un adhesivo.Currently there are devices for folding parts of cardboard boxes that basically include a rotating element that in their movement they drag the cardboard part down as flaps that are part of triangular reinforcing columns, so that at the end of their despondency these flaps do butt against the inner faces of the side walls to join them by means of an adhesive.
No obstante, este elemento giratorio actúa sobre unos extremos de las solapas, ya que el mismo inicia el movimiento desde una parte exterior de la caja siendo preciso salvar el borde superior de las paredes laterales, con lo cual la presión ejercida al final del abatimiento sobre tales solapas para que se peguen está totalmente descompensada.However, this rotating element acts on ends of the flaps, since it starts the movement from a outer part of the box being necessary to save the upper edge of the side walls, with which the pressure exerted at the end of the dejection on such flaps so that they stick together totally decompensated
El dispositivo para plegar partes de cajas de cartón que constituye el objeto de la invención comprende un brazo basculante que se caracteriza porque posee la combinación simultánea de un movimiento giratorio y un movimiento axial para llevar a cabo el abatimiento de partes de cajas, tales como solapas de columnas triangulares de refuerzo, de manera que al inicio del abatimiento un rodillo terminal loco conectado al brazo basculante arrastra a las solapas contactando con ellas desde una posición superior justamente por encima del borde correspondiente de las paredes laterales de la caja, de manera que una vez salvado el borde de la pared lateral correspondiente, se produce un desplazamiento axial progresivo del brazo hacia el interior de la caja y por lo tanto del área de contacto del rodillo terminal sobre las solapas.The device for folding parts of cardboard boxes that constitutes the object of the invention comprises a swing arm which is characterized because it has the simultaneous combination of a rotating movement and axial movement to carry out the folding parts of boxes, such as column flaps triangular reinforcement, so that at the beginning of the abatement a crazy terminal roller connected to the swing arm drags at flaps contacting them from a higher position just above the corresponding edge of the walls sides of the box, so that once saved the edge of the corresponding side wall, axial displacement occurs progressive arm towards the inside of the box and therefore of the contact area of the terminal roller on the flaps.
Al final del abatimiento, cuando las solapas alcanzan su posición definitiva haciendo tope contra la cara interior de las paredes laterales para pegarse contra ellas, el rodillo estará contactando en una zona central de las solapas con respecto a su altura y con respecto a las líneas de doblez correspondientes, lográndose así un equilibrio y reparto de la fuerza ejercida por dicho rodillo.At the end of the gloom, when the flaps reach their final position butt against the inside of the side walls to stick against them, the roller will be contacting in a central area of the flaps with respect to their height and with respect to the corresponding bending lines, thus achieving a balance and distribution of the force exerted by said roller.
De esta forma existe una simetría en cuanto al punto de presión del rodillo con respecto a las solapas y evidentemente con respecto a la banda de adhesivo impregnada previamente.In this way there is a symmetry regarding the pressure point of the roller with respect to the flaps and obviously with respect to the previously impregnated adhesive band.
Después, el brazo basculante recupera su posición inicial llevando a cabo el mismo giro y desplazamiento axial, pero en sentidos contrarios salvando la pared lateral correspondiente de la caja.Then, the swing arm recovers its initial position performing the same rotation and axial displacement, but in opposite senses saving the corresponding side wall of the box.
El dispositivo comprende una estructura que se caracteriza porque incluye el brazo con una configuración angular dispuesta en un plano horizontal, de manera en uno de los extremos se conecta el rodillo loco dirigido hacia abajo, mientras que en el otro extremo se conecta perpendicular y solidariamente un eje cilíndrico dirigido hacia arriba ajustado en un hueco complementario de un soporte fijo solidario de la estructura de la máquina que arma las cajas.The device comprises a structure that is characterized because it includes the arm with an angular configuration arranged in a horizontal plane, so that one of the ends connects the crazy roller directed down while at the other end a cylindrical shaft is connected perpendicularly and in solidarity directed upwards adjusted in a complementary hollow of a fixed support of the structure of the machine that assembles the boxes
A su vez, el eje cilíndrico se fija por su extremo libre a una biela conectada a un vástago de un cilindro neumático conectado por su extremo posterior a la estructura de la máquina mediante una conexión articulada en dos direcciones perpendiculares para permitir un correcto funcionamiento del dispositivo.In turn, the cylindrical shaft is fixed at its free end to a connecting rod connected to a rod of a pneumatic cylinder connected by its rear end to the machine structure by means of a articulated connection in two perpendicular directions for allow proper operation of the device.
El desplazamiento del vástago del cilindro realizará el giro del eje cilíndrico, mientras que el desplazamiento axial se consigue indirectamente gracias a una ranura a modo de leva que incorpora tal eje y en la cual se encaja una porción terminal de una corta varilla encastrada en el soporte.The displacement of the cylinder rod will rotate the cylindrical shaft, while axial displacement is achieved indirectly thanks to a cam-like slot that incorporates such axis and in which an end portion of a cut is fitted rod embedded in the support.
Dicha ranura posee un corto tramo inicial perpendicular a la generatriz del eje cilíndrico y un tramo de ranura más alargado que sigue una trayectoria helicoidal.Said slot has a short initial section perpendicular to the generatrix of the cylindrical shaft and a longer stretch of groove than Follow a helical path.
Gracias al corto tramo inicial de ranura, en el principio del movimiento se produce un giro sin movimiento axial con el fin de salvar el borde de la pared de la caja, en proximidad al mismo, de manera que después de este movimiento inicial donde se ha salvado y sobrepasado el borde libre de la pared lateral correspondiente, se produce la combinación de los dos movimientos del brazo: giratorio y axial.Thanks to the short initial slot section, at the beginning of the movement a rotation occurs without axial movement in order to save the edge of the wall of the box, in proximity to it, of so that after this initial move where it has been saved and exceeded the free edge of the corresponding side wall, it produces the combination of the two arm movements: swivel and axial.
No obstante, el tramo inicial de la ranura podría tener también una ligera inclinación con respecto a un plano perpendicular a la generatriz del eje afectado de la ranura correspondiente.However, the initial section of the groove could also have a slight inclination with respect to a plane perpendicular to the generatrix of the affected axis of the corresponding slot.
El rodillo loco facilita el doblado de las solapas al no existir ningún tipo de rozamiento ni fricción. Por otro lado, el elemento motor que hace girar al eje cilíndrico podría estar determinado por cualquier otro sistema, tal como un pequeño motor conectado directamente al eje cilíndrico, o bien de forma indirecta mediante piñones.The crazy roller facilitates the folding of the flaps when it does not exist No friction or friction. On the other hand, the element motor that rotates the cylindrical shaft could be determined by any other system, such as a small connected motor directly to the cylindrical axis, or indirectly by pinions.
También cabe señalar que el eje cilíndrico podría incorporar un tetón saliente y la ranura a modo de leva situarla en la cara interior del hueco del soporte fijo donde juega y encaja el citado eje cilíndrico.It should also be noted that the cylindrical shaft could incorporate a protruding stud and cam groove place it on the face inside the hollow of the fixed support where the aforementioned plays and fits cylindrical shaft
A continuación para facilitar una mejor comprensión de esta memoria descriptiva y formando parte integrante de la misma se acompañan unas figuras en las que con carácter ilustrativo y no limitativo se ha representado el objeto de la invención.Below to facilitate a better understanding of this descriptive report and being an integral part of it accompany some figures in which with an illustrative nature and not limiting the object of the invention has been represented.

Considerando la numeración adoptada en las figuras, el dispositivo para plegar partes de cajas de cartón se determina a partir de un brazo angular basculante 1 dispuesto en un plano horizontal, de uno de cuyos extremos arranca perpendicularmente hacia arriba un eje cilíndrico 2 encajado en un hueco complementario 3 de un soporte fijo 4 solidario del conjunto de una máquina 5 de armado de cajas de cartón 6.Considering the numbering adopted in the figures, the device for folding parts of cardboard boxes is determined to from a tilting angular arm 1 arranged in a plane horizontal, one of whose ends starts perpendicularly upwards a cylindrical shaft 2 embedded in a hole complementary 3 of a fixed support 4 integral with the assembly of one machine 5 for assembling cardboard boxes 6.
El eje cilíndrico 2 asoma por encima del soporte fijo 4, a la vez que se une por su extremo libre a una biela 7 conectada a su vez articuladamente al vástago de un cilindro neumático 8 acoplado por su extremo posterior a la estructura de la máquina 5 mediante dos conexiones articuladas perpendiculares entre sí 9 que permiten una total movilidad del cilindro neumático 8 y del conjunto del dispositivo de la invención.The cylindrical shaft 2 appears above the fixed support 4, at the once it joins at its free end to a connecting rod 7 connected to its articulated to the rod of a pneumatic cylinder 8 coupled by its rear end to the structure of the machine 5 by two articulated connections perpendicular to each other 9 that allow total mobility of the pneumatic cylinder 8 and the whole of the device of the invention.
Por otro lado, el eje cilíndrico 2 cuenta con una ranura a modo de leva 10 que posee un corto tramo inicial perpendicular a la generatriz de dicho eje y un tramo más largo que sigue una trayectoria helicoidal, encajándose en dicha ranura complementariamente una porción terminal 11 de una varilla 12 encastrada en el soporte fijo 4, de manera que ese tramo terminal 11 asoma por el interior del hueco 3 del soporte fijo 4 donde se ajusta el eje cilíndrico 2.On the other hand, the cylindrical shaft 2 has a groove like of cam 10 which has a short initial section perpendicular to the generatrix of said axis and a longer section that follows a helical path, fitting into said slot in addition a terminal portion 11 of a rod 12 embedded in the fixed support 4, so that that terminal section 11 appears inside the hole 3 of the fixed support 4 where adjust the cylindrical shaft 2.
En el extremo libre del brazo angular 1 se conecta perpendicularmente hacia abajo un rodillo loco 13 que es el elemento que contacta en todo momento con las solapas 14 y 15 constitutivas de unas columnas triangulares de refuerzo para llevar a cabo su plegado hasta la posición definitiva, constituyendo dichas solapas las partes de caja a plegar.At the free end of the angular arm 1 it connects perpendicularly down a crazy roller 13 which is the element that contacts at all times with the flaps 14 and 15 constitutive of triangular reinforcement columns to carry carried out its folding to the final position, constituting said flaps the box parts to be folded.
Para ello, estando la caja 6 a medio armar y estando las citadas solapas 14 y 15 dispuestas contra las caras internas, por ejemplo de los costados y asomando las solapas por encima del borde libre de tales costados, al actuar el cilindro neumático 8 se inicia entonces el abatimiento de las solapas 14 y 15 sobre cuya parte superior contacta el rodillo loco 13 desde el exterior de la caja 6, de manera que en el inicio del movimiento sólo se produce un giro del brazo angular 1 debido al corto tramo inicial de la ranura 10 del eje cilíndrico 2.To do this, the box 6 being half-assembled and those mentioned flaps 14 and 15 arranged against the inner faces, for example from the sides and sticking the flaps over the free edge of such sides, when the pneumatic cylinder 8 acts, it starts then the dejection of the flaps 14 and 15 on whose part upper contact the idler roller 13 from the outside of the box 6, so that at the beginning of the movement only one rotation of angular arm 1 due to the short initial section of the groove 10 of the cylindrical shaft 2.
En una fase posterior, una vez salvado el borde del costado, el brazo 1 realiza un movimiento combinado de giro y descenso progresivo a medida que se abaten las solapas 14 y 15 hasta su plegado total donde la solapa más extrema 14 hace tope, se adosa y se pega contra el testero correspondiente de la caja 6 habiendo impregnado previamente una banda de adhesivo, de manera que al final del abatimiento, el rodillo loco 13 presiona sobre las solapas en unas áreas centrales en relación con su altura, con lo cual se consigue un mejor reparto de fuerzas a fin de que el plegado sea más equilibrado y la solapa extrema 14 se pegue mejor al estar la misma sometida en toda su superficie de pegado prácticamente con una presión homogénea.At a later stage, once the edge of the side is saved, the arm 1 performs a combined twist and descent movement progressive as flaps 14 and 15 are pulled down until total folding where the most extreme flap 14 stops, is attached and sticks against the corresponding box 6 box previously impregnated a band of adhesive, so that when end of despondency, the idler roller 13 presses on the flaps in central areas in relation to their height, with which one gets a better distribution of forces so that the folded be more balanced and the extreme flap 14 sticks better to be the same subject in all its surface of pasted practically with a homogeneous pressure.
El movimiento combinado se produce cuando la porción terminal 11 de la varilla 12 se encuentra en el tramo helicoidal de la ranura a modo de leva 10.The combined movement occurs when the terminal portion 11 of the rod 12 is in the helical section of the groove a cam mode 10.
