Description
SISTEMA PARA PARADA DE PIEZAS IMPULSADAS POR UNA MANGUERA MEDIANTE AIRE A PRESIÓN SYSTEM FOR STOPPING PARTS PUSHED BY A HOSE BY PRESSURE AIR
La presente memoria descriptiva se refiere, como su título indica, a un sistema para parada de piezas impulsadas por una manguera mediante aire a presión, del tipo de los utilizados en dispositivos de mecanizado o remachado automáticos para el suministro automático de piezas con sección circular en su parte más ancha, caracterizado porque utiliza para la deceleración y frenado una pinza longitudinalmente ranurada, con exterior cónico e interior cilindrico, dispuesta entre la terminación de la manguera y el receptor, y accionada para su apertura y cierre mediante un cilindro que dispone de un mecanizado cónico interior. The present specification refers, as its title indicates, to a system for stopping parts driven by a hose by means of pressurized air, of the type used in automatic machining or riveting devices for the automatic supply of parts with circular section in its widest part, characterized in that it uses a longitudinally grooved caliper for deceleration and braking, with a conical exterior and cylindrical interior, arranged between the end of the hose and the receiver, and operated for opening and closing by means of a cylinder that has a internal conical machining.
En la actualidad son ampliamente utilizadas las máquinas de mecanizado automático, normalmente basadas en brazos robot con cabezales intercambiables o múltiples, y que permiten realizar con gran precisión y rapidez gran número de operaciones, por ejemplo taladrado, avellanado, remachado, atornillado, etc.. Algunas de estas operaciones necesitan de un dispositivo automático de suministro de piezas, por ejemplo remaches o tornillos, que los traiga desde un almacén hasta el cabezal que los va a emplear, siendo común utilizar un sistema de alimentación neumático, basado en una manguera que comunica el almacén de piezas con el cabezal de mecanizado, a través de la cual se envían las piezas propulsadas por aire a gran presión. Al extremo de la manguera la pieza llega a un elemento, denominado comúnmente "transfer", que detiene la pieza al llegar a un receptor, la retiene normalmente por medios magnéticos, y la lleva mediante un giro al cabezal que la va a utilizar (por ejemplo a un cabezal remachador o a uno atornillador...).
Este procedimiento de trabajo presenta el inconveniente de que, dada la longitud de la manguera y la presión de aire necesaria para la impulsión de las piezas, estas piezas adquieren una gran velocidad, del orden de unos lOm./seg., que, a pesar de su reducida masa, ocasiona que lleguen al receptor situado al final de la manguera con una elevada energía cinética que, al detenerse en seco, origina deformaciones en las piezas y un elevado desgaste en el receptor del transfer. Esto origina por un lado el problema de la deformación de las propias piezas, con el agravante de que se suele producir por la parte de la pieza que luego, al ser posicionada por el cabezal, queda oculta, dando lugar a problemas de fiabilidad, malos posicionamientos, y otras situaciones que únicamente se pueden descubrir mediante un exhaustivo control de calidad posterior. Por otro lado se produce también el problema del desgaste y deformaciones en el receptor, requiriendo una frecuente sustitución de este elemento, lo cual obliga a cortos plazos de mantenimiento del transfer, encareciendo el proceso productivo por los tiempos muertos de detención para su cambio. At present, automatic machining machines are widely used, usually based on robot arms with interchangeable or multiple heads, and that allow a large number of operations to be carried out with great precision and speed, for example drilling, countersinking, riveting, screwing, etc. Some of these operations require an automatic device for supplying parts, for example rivets or screws, that bring them from a warehouse to the head that will use them, being common to use a pneumatic feeding system, based on a hose that communicates the parts warehouse with the machining head, through which the parts propelled by high pressure air are sent. At the end of the hose the piece reaches an element, commonly called "transfer", which stops the piece when it reaches a receiver, normally retains it by magnetic means, and takes it by a turn to the head that is going to use it (by example to a riveting head or a screwdriver ...). This working procedure has the disadvantage that, given the length of the hose and the air pressure necessary for the delivery of the parts, these parts acquire a high speed, of the order of about 10m / sec, which, despite of its reduced mass, it causes them to reach the receiver located at the end of the hose with a high kinetic energy that, when stopped dry, causes deformations in the parts and high wear on the transfer receiver. This causes on the one hand the problem of deformation of the pieces themselves, with the aggravating factor that is usually produced by the part of the piece that then, when positioned by the head, is hidden, giving rise to problems of reliability, bad positioning, and other situations that can only be discovered through a thorough subsequent quality control. On the other hand, there is also the problem of wear and deformation in the receiver, requiring frequent replacement of this element, which requires short periods of maintenance of the transfer, making the production process more expensive due to the downtimes for its change.
Para solventar estos problemas existentes en el suministro de piezas por manguera por aire a presión, y la necesaria detención de las piezas, se ha ideado el sistema para parada de piezas impulsadas por una manguera mediante aire a presión objeto de la presente invención, el cual utiliza para la deceleración y frenado una pinza dispuesta entre la terminación de la manguera y el receptor, accionada para su apertura y cierre mediante un cilindro neumático que dispone de un mecanizado cónico interior. To solve these problems in the supply of parts by hose by pressurized air, and the necessary stopping of the parts, the system for stopping parts driven by a hose by means of pressurized air object of the present invention has been devised, which it uses a caliper arranged between the hose termination and the receiver for deceleration and braking, operated for opening and closing by means of a pneumatic cylinder that has an internal conical machining.
La pinza está longitudinalmente ranurada, con un exterior cónico y un interior cilindrico de medidas acordes para permitir el paso, en su estado abierto, de la pieza. The clamp is longitudinally grooved, with a conical exterior and a cylindrical interior of suitable measures to allow the passage, in its open state, of the piece.
Al lanzar la pieza desde el almacén se acciona el cilindro neumático, con lo que su mecanizado cónico interior presiona la parte exterior cónica de la pinza, la cual por efecto de su ranurado longitudinal
tiene una cierta elasticidad, produciéndose su cierre, quedando el diámetro interior del conducto cilindrico interno con una conicidad ya que por su extremo de entrada el conducto mantenga su diámetro original, pero por el extremo de salida, presionado por el cilindro, se ha reducido el diámetro ligeramente lo suficiente para impedir el paso de la pieza. La pieza que llega a gran velocidad, con gran energía cinética, se ve decelerada progresivamente por rozamiento, merced a la conicidad, hasta detenerse bloqueada por la pinza en la zona de mayor diámetro de la pieza, perdiendo toda su energía cinética. El aire a presión, mientras tanto, escapa por las ranuras de la pinza, evitando quedar almacenado en el tubo, detrás de la pieza, formando un calderín en el tubo de tal forma que no ocurra que cuando se libere la pieza nuevamente esta sea impulsada de nuevo a gran velocidad. When the piece is launched from the warehouse, the pneumatic cylinder is operated, so that its inner conical machining presses the conical outer part of the clamp, which, due to its longitudinal grooving effect It has a certain elasticity, producing its closure, leaving the inner diameter of the internal cylindrical duct with a conicity since at its inlet end the duct maintains its original diameter, but by the outlet end, pressed by the cylinder, the diameter slightly enough to prevent the passage of the piece. The piece that arrives at high speed, with great kinetic energy, is progressively decelerated by friction, thanks to the taper, until it stops blocked by the clamp in the area of greater diameter of the piece, losing all its kinetic energy. The pressurized air, meanwhile, escapes through the grooves of the clamp, avoiding being stored in the tube, behind the piece, forming a boiler in the tube so that it does not happen that when the piece is released again it is driven again at great speed.
A continuación se desplaza el cilindro, liberando la parte delantera de la pinza, lo cual provoca que la pieza quede libre y prosiga libremente, impulsada por el aire a presión proveniente de la manguera, hasta el receptor, donde se posiciona y detiene definitivamente. Dado que la distancia entre la pinza y el receptor es mínima la pieza no tiene tiempo de acelerar suficientemente con lo cual la energía cinética adquirida es mínima, evitándose los daños en la pieza. Then the cylinder moves, releasing the front part of the clamp, which causes the piece to be free and continue freely, driven by the pressurized air coming from the hose, to the receiver, where it is positioned and stops definitively. Since the distance between the clamp and the receiver is minimal, the part does not have time to accelerate sufficiently, so that the kinetic energy acquired is minimal, avoiding damage to the part.
Los principales elementos integrantes del sistema está previsto que estén alojados en un cartucho de estructura cuadrangular, apto tanto para su inserción dentro del transfer, durante su proceso de fabricación, como para su adaptación externa a transfer preexistentes. Este sistema para parada de piezas impulsadas por una manguera mediante aire a presión que se presenta aporta múltiples ventajas sobre los sistemas disponibles en la actualidad siendo la más importante que consigue una óptima deceleración y frenado de la pieza de sección circular, permitiéndole posicionarse suavemente en el receptor y evitando los daños y deformaciones en la parte útil de la pieza y en el receptor.
Otra importante ventaja es que, en el caso de que la pieza sea un remache, la sujeción en la pinza se produce en la parte sobrante de dicho remache debido a su mayor diámetro, que sirve únicamente para su montaje, desechándose posteriormente, con lo cual cualquier posible deformación producida por el frenado en la pinza se realizaría en la parte no útil y desechable, no sufriendo ningún esfuerzo el remache propiamente dicho. The main elements of the system are expected to be housed in a quadrangular structure cartridge, suitable both for insertion into the transfer, during its manufacturing process, and for its external adaptation to pre-existing transfers. This system for stopping parts driven by a hose by means of pressurized air that is presented provides multiple advantages over the systems currently available, the most important being that it achieves optimum deceleration and braking of the circular section piece, allowing it to position itself gently in the receiver and avoiding damage and deformation in the useful part of the piece and in the receiver. Another important advantage is that, in the case that the piece is a rivet, the clamping on the clamp is produced in the remaining part of said rivet due to its larger diameter, which is only used for assembly, later discarded, with which Any possible deformation caused by the braking on the caliper would be carried out on the non-useful and disposable part, the rivet itself not suffering any effort.
Otra ventaja de la presente invención es que alarga notablemente la duración del receptor del transfer, permitiendo alargar los tiempos de mantenimiento, lo cual redunda en un descenso de su coste económico. Another advantage of the present invention is that it significantly lengthens the duration of the transfer receiver, allowing the maintenance time to be lengthened, which results in a decrease in its economic cost.

El sistema para parada de piezas impulsadas por una manguera mediante aire a presión objeto de la presente invención, comprende básicamente, como puede apreciarse en el plano anexo, una pinza (1) para la deceleración y frenado dispuesta entre la terminación de la manguera (2) y el receptor (3), accionada para su apertura y cierre mediante un cilindro (4) neumático que dispone de un mecanizado cónico interior. The system for stopping parts driven by a hose by means of pressurized air object of the present invention basically comprises, as can be seen in the attached drawing, a caliper (1) for deceleration and braking arranged between the termination of the hose (2 ) and the receiver (3), operated for opening and closing by means of a pneumatic cylinder (4) that has an internal conical machining.
La pinza (1) está dotada de un ranurado longitudinal (15), con un exterior (5) cónico y un conducto (6) interior cilindrico de medidas acordes para permitir el paso, en su estado abierto, de la pieza (7). The clamp (1) is provided with a longitudinal groove (15), with a conical exterior (5) and a cylindrical inner duct (6) of suitable measures to allow the passage (in its open state) of the piece (7).
Tanto la pinza (1), como el cilindro (4), como los conductos de entrada (8) y salida (9) para la pieza, las tomas de aire de cierre (10) y apertura (11) y un sensor de posición (12) para el cilindro (4) se encuentran integrados en la forma de un cartucho (13) cuadrangular que ejerce la función de camisa y soporte. Este cartucho (13) puede integrarse dentro del transfer (17), o bien disponerse al lado de un transfer (17) convencional. Both the clamp (1), and the cylinder (4), as the inlet (8) and outlet (9) ducts for the part, the closing air intakes (10) and opening (11) and a position sensor (12) for the cylinder (4) are integrated in the form of a quadrangular cartridge (13) that acts as a sleeve and support. This cartridge (13) can be integrated into the transfer (17), or arranged next to a conventional transfer (17).
Su funcionamiento se compone de dos etapas, una de cierre y otra de apertura. Normalmente se encuentre en la etapa de cierre gracias al accionamiento del cilindro (4) neumático, mediante la inyección de aire por la toma de cierre (10), con lo que su mecanizado cónico interior presiona la
parte exterior cónica de la pinza (1), la cual por efecto de su ranurado longitudinal (15) tiene una cierta elasticidad, produciéndose su cierre, quedando el diámetro interior del conducto (6) cilindrico interno con una conicidad ya que por su extremo de entrada el conducto (6) mantiene su diámetro original, pero por el extremo de salida, presionado por el cilindro (4), se ha reducido el diámetro ligeramente lo suficiente para impedir el paso de la pieza (7). La pieza (7) que llega a gran velocidad, con gran energía cinética, se ve decelerada progresivamente por rozamiento con las paredes interiores del conducto (6), merced a la conicidad, hasta detenerse bloqueada por la pinza (7) en la zona de mayor diámetro de la pieza (7), perdiendo toda su energía cinética. El aire a presión (16), mientras tanto, escapa por el ranurado longitudinal (15) de la pinza (1), evitando quedar almacenado en la manguera (2), detrás de la pieza (7), formando un calderín en la manguera (2) de tal forma que no ocurra que cuando se libere la pieza (7) nuevamente esta sea impulsada de nuevo a gran velocidad. Its operation consists of two stages, one of closing and another of opening. Normally it is in the closing stage thanks to the actuation of the pneumatic cylinder (4), by means of the injection of air by the closing socket (10), with which its inner conical machining presses the conical outer part of the clamp (1), which due to its longitudinal grooving (15) has a certain elasticity, producing its closure, leaving the inner diameter of the internal cylindrical duct (6) with a taper since its end of Inlet the duct (6) maintains its original diameter, but at the outlet end, pressed by the cylinder (4), the diameter has been reduced slightly enough to prevent the passage of the piece (7). The piece (7) that arrives at high speed, with great kinetic energy, is progressively decelerated by friction with the inner walls of the duct (6), thanks to the taper, until it stops blocked by the clamp (7) in the area of larger diameter of the piece (7), losing all its kinetic energy. The pressurized air (16), meanwhile, escapes through the longitudinal grooving (15) of the clamp (1), avoiding being stored in the hose (2), behind the part (7), forming a boiler in the hose (2) in such a way that it does not happen that when the part (7) is released again it is driven again at high speed.
Al detectarse la llegada de la pieza (7) por la manguera (2), mediante un oportuno detector magnético (14) instalado en ella y con la oportuna temporización para dejar que se produzca el frenado, se procede a la etapa de apertura, a continuación de la anterior, en la que se desplaza el cilindro (4), mediante la inyección de aire por la toma de apertura (11), liberando la parte delantera de la pinza (1), lo cual provoca que la pieza (7) quede libre y prosiga libremente, impulsada por el aire a presión (16) proveniente de la manguera (2), hasta el receptor (3), donde se posiciona y detiene definitivamente. Dado que la distancia entre la pinza (1) y el receptor (3) es mínima la pieza (7) no tiene tiempo de acelerar suficientemente con lo cual la energía cinética adquirida es mínima, evitándose los daños en dicha pieza (7). When the arrival of the part (7) is detected by the hose (2), by means of a suitable magnetic detector (14) installed in it and with the appropriate timing to allow the braking to occur, the opening stage is carried out, a continuation of the previous one, in which the cylinder (4) moves, by means of the injection of air through the opening socket (11), releasing the front part of the clamp (1), which causes the piece (7) remain free and proceed freely, driven by the pressurized air (16) from the hose (2), to the receiver (3), where it is definitely positioned and stopped. Since the distance between the clamp (1) and the receiver (3) is minimal the part (7) does not have time to accelerate sufficiently with which the kinetic energy acquired is minimal, avoiding damages in said part (7).
Este sistema de aplicación es de especial uso para cualquier pieza (7) de sección circular en su parte más ancha susceptible de ser distribuida o transportada por una manguera (2) mediante aire a presión
(16), especialmente remaches, tortillería, bolas para cojinetes o rodamientos, etc...
This application system is of special use for any part (7) of circular section in its widest part that can be distributed or transported by a hose (2) by means of pressurized air (16), especially rivets, tortilleria, balls for bearings or bearings, etc ...
