REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las mencionadas figuras y de acuerdo con la numeración adoptada, se puede observar en ellas un ejemplo de realización preferente de la máquina para la mecanización parcial de sofás, sillones y similares perfeccionada que comprende las partes que se indican y describen a continuación. Así, tal como se aprecia en las figuras 1 y 2, la máquina en cuestión está constituida a partir de un utillaje (1) móvil, en el cual se sujeta el bastidor del sofá (S) permitiendo a éste realizar varios movimientos a demanda del operario, y una grapadora (2) automatizada que permite colocar una línea de grapas cuyos extremos son definidos por el operario, y que en otras variantes de realización de la máquina puede tratarse de cualquier otro tipo de robot mecanizado que realice una función automatizada distinta sobre el mencionado sofá (S) .In view of the aforementioned figures and in accordance with the numbering adopted, an example of a preferred embodiment of the machine for the partial machining of sofas, armchairs and similar perfected comprising the parts indicated and described below can be observed . Thus, as can be seen in figures 1 and 2, the machine in question is constituted from a mobile tooling (1), in which the sofa frame (S) is fastened, allowing the latter to make several movements at the request of the operator, and an automated stapler (2) that allows to place a line of staples whose ends are defined by the operator, and which in other variants of the machine can be any other type of mechanized robot that performs a different automated function on the mentioned sofa (S).
El utillaje, tal como se aprecia en las figuras 3 y 4, permite realizar tres movimientos al sofá (S) , que consisten en un movimiento vertical de elevación y descenso, para poder amarrarlo y/o soltarlo cuando esté descansando en el suelo así como situarlo a la altura de trabajo más conveniente, un movimiento de balanceo, es decir, alrededor de un eje horizontal, perpendicularmente al respaldo del sofá (S) de unos 30° en cada sentido, y un movimiento de cabeceo sobre un eje horizontal perpendicular al anterior, y por tanto paralelo al respaldo, de unos 210°, de forma que en una posición extrema, el sofá esté invertido respecto a su posición habitual y, en la contraria, se incline hacia delante unos 30°.The tooling, as seen in figures 3 and 4, allows three movements to the sofa (S), which consist of a vertical movement of elevation and descent, to be able to tie it and / or release it when it is resting on the ground as well as place it at the most convenient working height, a rocking motion, that is, around a horizontal axis, perpendicular to the back of the sofa (S) of about 30 ° in each direction, and a pitching movement on a horizontal axis perpendicular to the anterior, and therefore parallel to the backrest, of about 210 °, so that in an extreme position, the sofa is inverted from its usual position and, on the contrary, tilts forward about 30 °.
En la figura 5 se observa que el movimiento vertical se realiza a partir de un conjunto (10) , formado por un cilindro hidráulico (14) que presenta un soporte (11) , un carril (12) , un carro de recirculación de bolas (13), el cilindro hidráulico (14) propiamente dicho, una columna de elevación (15), ejes (16) de las palancas del mecanismo de cabeceo y una sujeción (17) posterior del cilindro de cabeceo. Es decir, este movimiento de desplazamiento lineal se logra con el cilindro hidráulico (14) con la colaboración de una columna telescópica, de forma tal que la columna de elevación (15) se desliza sobre el soporte (11) por medio de guias lineales comerciales, disponiendo de reglas de desplazamiento en el movimiento vertical de forma que el autómata que controla la máquina sepa en cada momento cual su la posición.In figure 5 it can be seen that the vertical movement is made from a set (10), formed by a hydraulic cylinder (14) that has a support (11), a rail (12), a ball recirculation carriage ( 13), the hydraulic cylinder (14) itself, a lifting column (15), axes (16) of the levers of the pitching mechanism and a rear clamp (17) of the pitching cylinder. That is, this linear displacement movement is achieved with the hydraulic cylinder (14) with the collaboration of a telescopic column, so that the lifting column (15) slides on the support (11) by means of commercial linear guides , having displacement rules in the vertical movement so that the automaton that controls the machine knows at all times what its position.
En la figura número 6, se observa el mecanismo de cabeceo, referenciado de forma general conIn figure 6, the pitching mechanism is observed, generally referenced with

Este movimiento de cabeceo se logra por medio de las mencionadas palancas (24), (25) y (26) o barras articuladas situadas en el extremo superior de la columna de elevación (21) y accionadas por medio del cilindro hidráulico (22) .This pitching movement is achieved by means of the mentioned levers (24), (25) and (26) or articulated bars located at the upper end of the lifting column (21) and actuated by means of the hydraulic cylinder (22).
El mecanismo de balanceo (30) , tal como se observa en las figuras 7A y 7B, está formado por sendas palancas (31), una mesa para balanceo (32), un cilindro (34) y un eje de balanceo (35) .The balancing mechanism (30), as seen in Figures 7A and 7B, is formed by two levers (31), a balancing table (32), a cylinder (34) and a balancing axis (35).
El movimiento de balanceo se realiza situando una base o mesa de balanceo (32) bajo la última palanca (26) del mecanismo constitutivo del movimiento de cabeceo (20), en la cual se dispone una articulación unida al extremo del cilindro (34) , estando su otro extremo unido a una palanca (31) , lográndose la inclinación de la mesa (32) al moverse el vastago del cilindro (34) .The balancing movement is carried out by placing a base or balancing table (32) under the last lever (26) of the mechanism constituting the pitching movement (20), in which an articulation is arranged attached to the end of the cylinder (34), its other end being attached to a lever (31), the inclination of the table (32) being achieved by moving the rod of the cylinder (34).
Tanto este mecanismo de cabeceo (20) como el de balanceo (30) , están provistos en sus correspondientes ejes (23) y (35) de encoders de giro como sistema de medida para control de su posición por parte del autómata.Both this pitching mechanism (20) and the balancing mechanism (30), are provided on their corresponding axes (23) and (35) of rotation encoders as a measuring system for controlling their position by the automaton.
Por su parte, el mecanismo de amarre (40) , tal como se observa en las figuras 8A y 8B, que consigue fijar el bastidor (41) de sofá (S) o mueble de asiento, está formado por cuatro pinzas de amarre (42) , accionadas mediante correspondientes cilindros neumáticos (43) y sujetas a guias (44) , que a su vez se acoplan una estructura o bastidor de amarre (45) provisto de bulones (46) , consiguiendo retener la estructura del sofá (S) , realizándose siempre entre los dos largueros centrales del bastidor (41) cuando se trate de un sofá de tamaño grande, entre el larguero central y uno de los laterales del bastidor (41) cuando se. trate de sofás pequeños, y entre los laterales en el caso de que se pretendan tapizar sillones.For its part, the mooring mechanism (40), as seen in Figures 8A and 8B, which manages to fix the sofa frame (41) or seat furniture, is formed by four clamp clamps (42 ), actuated by means of corresponding pneumatic cylinders (43) and subject to guides (44), which in turn are attached to a structure or mooring frame (45) provided with bolts (46), managing to retain the structure of the sofa (S), always being made between the two central stringers of the frame (41) when it is a large sofa, between the central stringer and one of the sides of the frame (41) when it is. try small sofas, and between the sides in the case that you intend to upholster armchairs.
En síntesis, el mecanismo de amarre se basa en el uso de unas pinzas (42) accionadas neumáticamente y, a su vez, estas pinzas (42) se deslizan sobre las guias (44) en orden a ajustarse a la posición que tengan los largueros o los laterales del sofá (S) .In summary, the mooring mechanism is based on the use of pneumatically operated clamps (42) and, in turn, these clamps (42) slide on the guides (44) in order to adjust to the position of the stringers or the sides of the sofa (S).
Opcionalmente el amarrado al bastidor (41) del sofá (S) , se puede realizar mediante atornillado de las pinzas (42) en lugar de mediante la acción de los cilindros neumáticos (43) , configurándose el conjunto del mecanismo de amarre (40) como un bastidor auxiliar metálico y ajustable que se puede unir al utillaje de tapizado a través de los bulones (6) asi como a cualquier otro tipo de máquina y que queda fijado al bastidor (41) del sofá (S) durante todo el proceso, permitiendo un movimiento automatizado entre puesto y puesto, en que en cada uno de dichos puestos exista por ejemplo un utillaje móvil (1) como el descrito u otro tipo de máquina, siendo para ello sujetado a una máquina antes de soltarse de la anterior por medio de los mencionados bulones (46) , facilitando asi el paso de un puesto a otro.Optionally, the fastening to the frame (41) of the sofa (S) can be done by screwing the clamps (42) instead of by means of the action of the pneumatic cylinders (43), configuring the assembly of the mooring mechanism (40) as a metal and adjustable auxiliary frame that can be attached to the upholstery tooling through the bolts (6) as well as to any other type of machine and that is fixed to the frame (41) of the sofa (S) during the whole process, allowing an automated movement between position and position, in which in each of these positions there is for example a mobile tooling (1) like the one described or another type of machine, being for this purpose attached to a machine before releasing from the previous one by means of the aforementioned bolts (46), thus facilitating the passage from one position to another.
Obviamente se constata que todos los movimientos (vertical, de cabeceo y de balanceo) del utillaje (1) se consiguen mediante elementos hidráulicos y el control de los mismos se realizará manualmente por medio de una botonera o automáticamente por medio de un autómata, que comandará a las electroválvulas que dan paso al fluido hidráulico a cada cilindro, disponiendo de sistemas de medida tales como encoders en los ejes de giro y reglas de desplazamiento en el movimiento vertical, de forma que el autómata que controla la máquina sepa en cada momento cual es la posición de cada uno de sus elementos .Obviously it is found that all movements (vertical, pitching and balancing) of the tooling (1) are achieved by hydraulic elements and their control will be carried out manually by means of a keypad or automatically by means of an automaton, which will command to the electrovalves that give way to the hydraulic fluid to each cylinder, having measurement systems such as encoders in the rotation axes and displacement rules in the vertical movement, so that the automaton that controls the machine knows at all times what it is the position of each of its elements.
Descrita suficientemente • la naturaleza de la presente invención, asi como la manera de ponerla en práctica, se hace constar que, dentro de su esencialidad, podrá ser llevada a la práctica en otras formas de realización que difieran en detalle de la indicada a titulo de ejemplo, y a las cuales alcanzará igualmente la protección que se recaba siempre que no se altere, cambie o modifique su principio fundamental. Described sufficiently • the nature of the present invention, as well as the way of putting it into practice, it is noted that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated by way of for example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify its fundamental principle.
