MECANISMO PARA LA TRANSFERENCIA DE ARTICULOS EN MAQUINAS FORMADORAS DE ARTICULOS DE VIDRIO. MECHANISM FOR THE TRANSFER OF ARTICLES IN GLASS ARTICLE FORMING MACHINES.
ANTECEDENTES DE LA INVENCIÓN. BACKGROUND OF THE INVENTION.
CAMPO DE LA INVENCIÓN. FIELD OF THE INVENTION.
La presente invención se relaciona con la producción de artículos de vidrio y, más específicamente, a un mecanismo para transferir artículos de vidrio de una estación de formado a una estación de soplo final en máquinas formadora de artículos de vidrio, del tipo que incluye múltiples secciones formadoras individuales, para la producción de botellas de vidrio, frascos de boca ancha, vasos y otros artículos de vidrio por los procesos soplo-soplo, prensa-soplo, prensa-soplo o prensa directa. The present invention relates to the production of glassware and, more specifically, to a mechanism for transferring glassware from a forming station to a final blowing station in glassware forming machines, of the type that includes multiple sections. individual forming machines, for the production of glass bottles, wide-mouth jars, glasses and other glass articles by the blow-blow, press-blow, press-blow or direct press processes.
ANTECEDENTES DE LA INVENCION. BACKGROUND OF THE INVENTION.
Los artículos de vidrio tales como las botellas de vidrio de cuello angosto, son normalmente producidos en máquinas formadoras de artículos de vidrio del tipo que pueden incluir múltiples secciones formadoras individuales similares, mediante el proceso soplo-soplo, mientras que tos frascos de boca ancha, los vasos y otros artículos de vidrio son producidos en las máquinas formadoras conocidas como Series "E" y "F" mediante el proceso prensa-soplo, en los así llamados“molde caliente". Glassware such as narrow neck glass bottles are normally produced on glassware forming machines of the type which may include multiple similar individual forming sections, by the blow-blow process, while coughing wide-mouth jars, the glasses and other glass articles are produced in the forming machines known as Series "E" and "F" by means of the press-blow process, in the so-called "hot mold".
En el proceso de fabricación de envases de vidrio mediante el proceso soplo-soplo o prensa soplo, el vidrio en forma de gotas, se introduce en un molde de parison o preformado, en donde, dependiendo del proceso, la gota se asienta, mediante un proceso de soplado o vacío, a la parte inferior del molde de parison, para formar la corona del envase. Después, una vez
formada la corona del envase, se efectúa un contrasoplo para formar un parison o preforma del envase. Posteriormente, la preforma del envase es transferida mediante un mecanismo de inversión con un movimiento de 180 grados de dicho molde de parison a un molde de soplado final en donde se da la forma final al envase. In the process of manufacturing glass containers using the blow-blow or press-blow process, the glass in the form of drops is introduced into a parison or preformed mold, where, depending on the process, the drop settles, by means of a blowing or vacuum process, to the bottom of the parison mold, to form the crown of the container. Then once Once the crown of the container is formed, a counter blow is made to form a parison or preform of the container. Subsequently, the preform of the container is transferred by means of an inversion mechanism with a 180 degree movement from said parison mold to a final blow mold where the final shape of the container is given.
El principal objetivo del mecanismo de invertir ha sido transferir el artículo del molde de parison al molde de soplo lo mejor posible, sin que el parison se deforme en la transferencia y regresar a su posición original para iniciar un nuevo ciclo de formado. The main objective of the reversing mechanism has been to transfer the article from the parison mold to the blow mold as best as possible, without the parison deforming in the transfer and returning to its original position to start a new forming cycle.
Sin embargo, debido al aumento en el número de cavidades (de dos a tres o cuatro) en las estaciones de formado y al aumento de las velocidades de producción de las máquinas formadoras, es muy importante controlar la velocidad de transferencia del mecanismo de invertir con una aceleración o desaceleración controlada. Esto es, debido a que existen más cavidades de molde, las preformas de envase se van alejando del centro de giro, provocando que la última preforma, sí se mantiene la misma velocidad de transferencia, llegue al molde de soplo final en forma combada, afectando la alineación con el molde de soplo y por consecuencia la calidad del producto final. Actualmente el perfil de movimiento de transferencia del mecanismo de invertir ha sido programado con una serie de velocidades con diversas aceleraciones y desaceleraciones, de tal forma que la transferencia de las diversas preformas puedan mantener su verticalidad durante su movimiento de transferencia (180 grados) hacia el molde de soplo.
Mecanismos de transferencia de artículos de vidrio se muestran, por ejemplo, en la patente Norteamericana No. 5843201, de Joseph A. Borbone et al, la cual se refiere a un mecanismo de portacoronas e inversión para transferir una preforma de una estación de preformado a una estación de soplado final. El mecanismo portacoronas e invertir tiene un par de soportes laterales opuestos, un alojamiento para un engranaje helicoidal para soportar un tomillo sinfín, y un alojamiento de motor/tornillo sinfín para soportar el alojamiento del engranaje helicoidal en una parte intermedia a los soportes laterales opuestos. El mecanismo portacoronas e invertir comprende un par de conjuntos de cilindro-pistón que se extienden entre las partes laterales de engranaje helicoidal y el par de soportes laterales. Los conjuntos de cilindro incluyen un cilindro que tiene un soporte. Cada cilindro se desplaza axialmente de una primera posición adyacente al engranaje helicoidal, a una segunda posición lugar adyacente a los soportes laterales asociados y rotacionalmente desplazables para desplazar el soporte sujetador de portacorona desde una primera posición en la estación de preformado a una segunda posición en estación de soplo. However, due to the increase in the number of cavities (from two to three or four) in the forming stations and the increase in the production speeds of the forming machines, it is very important to control the transfer speed of the inverting mechanism with a controlled acceleration or deceleration. That is, because there are more mold cavities, the container preforms move away from the center of rotation, causing the last preform, if the same transfer speed is maintained, to reach the final blow mold in a warped form, affecting the alignment with the blow mold and consequently the quality of the final product. Currently, the transfer movement profile of the inverting mechanism has been programmed with a series of speeds with different accelerations and decelerations, in such a way that the transfer of the various preforms can maintain their verticality during their transfer movement (180 degrees) towards the puff mold. Glassware transfer mechanisms are shown, for example, in U.S. Patent No. 5843201, to Joseph A. Borbone et al, which refers to a crown holder and reversing mechanism for transferring a preform from a preforming station to a final blowing station. The crown and reverse gear mechanism has a pair of opposite side supports, a housing for a worm gear to support a worm gear, and a motor / worm gear housing to support the worm gear housing in an intermediate part to the opposite side brackets. The crown and inverting mechanism comprises a pair of cylinder-piston assemblies extending between the helical gear side portions and the pair of side supports. Cylinder assemblies include a cylinder that has a bracket. Each cylinder is axially displaced from a first position adjacent to the worm gear, to a second position location adjacent to the associated, rotationally displaceable side supports to displace the crown holder fastening support from a first position in the preforming station to a second station position puff.
Un primer interruptor indica que un primer cilindro del conjunto de cilindro está próximo a su soporte lateral asociado, un segundo intermptor indica que el conjunto del primer cilindro-soporte de retención del portacoronas está en la primera posición, un tercer interruptor indica que el segundo cilindro del conjunto de cilindro está próximo a su soporte lateral asociado, y un cuarto interruptor indica que el conjunto del segundo cilindro y soporte de retención del portacoronas está en la segunda posición.

Finalmente, la Publicación Internacional No. W02017111570 (A1) de Finally, International Publication No. W02017111570 (A1) of
Víctor Tijerina se refiere a un mecanismo para la transferencia de artículos en máquinas formadoras de artículos de vidrio que comprende un par de columnas o alojamientos huecos que separados paralelamente y colocados verticalmente sobre una base de soporte. Un motor ubicado en la base de soporte tiene acoplado un primer engrane para girar con un movimiento hacia la izquierda o hacía la derecha. Una carcasa rotatoria, que contiene y soporta un mecanismo de retención y liberación de moldes corona y para abrir y cerrar paralelamente brazos de retención de corona y moldes de corona, esta acoplada mediante ejes de salida acoplados axialmente a la parte superior del par de columnas o alojamientos. Al menos un segundo engrane esta acoplado en uno de los ejes de salida de la carcasa rotatoria. Un engrane flotante acoplando el primer engrane y el segundo engrane, el engrane flotante siendo ajustable orbitalmente o linealmente, para reducir el juego o huelgo entre el primer engrane y segundo engrane, y reducir al mínimo el movimiento de impacto entre los mismos. Víctor Tijerina refers to a mechanism for the transfer of articles in glass article forming machines that comprises a pair of columns or hollow housings that are separated in parallel and placed vertically on a support base. A motor located in the support base has a first gear engaged to rotate with a movement to the left or to the right. A rotary housing, containing and supporting a crown mold retention and release mechanism and for parallel opening and closing of crown retention arms and crown molds, is coupled by output shafts axially coupled to the top of the pair of columns or accommodation. At least one second gear is coupled to one of the output shafts of the rotating housing. A floating gear coupling the first gear and the second gear, the floating gear being orbitally or linearly adjustable, to reduce clearance or play between the first gear and second gear, and minimize impact movement between them.
Sin embargo, uno de los principales problemas de los mecanismos de invertir conocidos es qué, para generar su movimiento requieren normalmente de un sistema de engranajes, sea del tipo cremallera y engranes o, de una serie de engranes conectados en serie. Dichos sistemas de engranaje pueden estar acoplados a un conjunto de cilindro-pistón para transmitir un movimiento rectilíneo hacía arriba y hacia abajo o hacía la
derecha e izquierda, para mover el mecanismo de invertir con un movimiento de rotación de 180 grados de una estación de formado de parison a una estación de soplo final y viceversa. However, one of the main problems with known reversing mechanisms is that, to generate their movement, they normally require a system of gears, be it rack and pinion type or a series of gears connected in series. Said gear systems can be coupled to a cylinder-piston assembly to transmit a rectilinear movement up and down or towards the right and left, to move the reverse mechanism with a 180 degree rotational motion from a parison forming station to a final blow station and vice versa.
Durante su funcionamiento, los engranajes del mecanismo de invertir están sometidos a desgaste tal como el deterioro que sufren los dientes y por el cual son removidos de sus superficies capas de metal de manera más o menos uniforme. Esta clase de desgaste reduce el espesor del diente y causa muchas veces grandes cambios en el perfil del mismo. Estos cambios, aunque se van presentando gradualmente, hacen que durante el inicio del movimiento del mecanismo de invertir, los dientes sean sometidos a contactos bruscos que pueden deberse a la desalineación o desequilibrado de los mismos produciendo vibraciones y ruidos. During operation, the gears of the inverting mechanism are subject to wear such as the deterioration suffered by the teeth and by which metal layers are removed more or less uniformly from their surfaces. This kind of wear reduces the thickness of the tooth and often causes large changes in the tooth profile. These changes, although they appear gradually, cause that during the beginning of the movement of the reverse mechanism, the teeth are subjected to sudden contacts that may be due to their misalignment or imbalance, producing vibrations and noise.
Aunado a lo anterior, una desalineación de los dientes puede producir un movimiento de vibración en el brazo de inversión en el lado de la preforma, es decir, una vez que se ha formado la preforma y las mitades del molde de bombillo se abren, el brazo del mecanismo de invertir recibe un movimiento de impulsión de un motor a través del sistema de engranajes y, si éstos están desgastados o desalineados, provocan una pequeña vibración antes de iniciar el movimiento de transferencia. In addition to the above, a misalignment of the teeth can produce a movement of vibration in the inversion arm on the side of the preform, that is, once the preform has been formed and the halves of the bulb mold are opened, the The reverse gear arm receives a drive motion from a motor through the gear system and, if worn or misaligned, causes a slight vibration before initiating the transfer motion.
Otra de las desventajas de los mecanismos conocidos es que algunos son bastante complejos, con bastante equipamiento, lo cual dificulta su mantenimiento o su intercambiabilidad en la estructura de la máquina. Another disadvantage of the known mechanisms is that some are quite complex, with enough equipment, which makes it difficult to maintain or interchange them in the structure of the machine.
Con el objeto de simplificar la construcción de los mecanismos que constituyen la máquina, buscando incrementar la velocidad de la máquina y
una reducción del tiempo del ciclo de formado, así como, reducir lo más posible el costo de equipamiento de una máquina y la simplicidad en el montaje de los instrumentos específicos de mecanismos y aparatos comunes, la presente invención se refiere a un mecanismo para la transferencia de artículos en máquinas formadoras de artículos de vidrio, el cual modular, de fácil construcción y que sea fácilmente intercambiable durante su mantenimiento. In order to simplify the construction of the mechanisms that make up the machine, seeking to increase the speed of the machine and a reduction of the time of the forming cycle, as well as, reducing as much as possible the cost of equipment of a machine and the simplicity in the assembly of the specific instruments of common mechanisms and apparatuses, the present invention refers to a mechanism for the transfer of articles in glass article forming machines, which are modular, easy to build and easily interchangeable during maintenance.
Otra desventaja de los mecanismos de transferencia conocidos es que, durante su ensamble, los brazos de inversión deben estar perfectamente alineados al tamaño y altura de los artículos de acuerdo a su radio de inversión. Para ello, los operarios ajustan los brazos individualmente, lo qué les lleva mucho tiempo, puesto que tienen que ajustar cada brazo con respecto al radio de giro y también con la alineación con ellos mismos. Another disadvantage of the known transfer mechanisms is that, during their assembly, the inversion arms must be perfectly aligned to the size and height of the articles according to their inversion radius. For this, the operators adjust the arms individually, which takes a long time, since they have to adjust each arm with respect to the turning radius and also with the alignment with themselves.
Para superar las desventajas anteriores, el inventor de la presente invención, que también es coinventor de la patente norteamericana No. To overcome the above disadvantages, the inventor of the present invention, who is also a co-inventor of US Patent No.
7779650, consideró que era posible simplificar el sistema de transmisión del mecanismo de invertir, facilitar la alineación de los brazos de inversión y, además, ajustar la altura de los brazos. 7779650, considered that it was possible to simplify the transmission system of the inverting mechanism, to facilitate the alignment of the inverting arms and, in addition, to adjust the height of the arms.
