Method and a machine for the production of hollow glassware articles

Abstract

A method and a machine for the production of hollow glassware articles, by the blow-and-blow, press-and-blow, press-and-blow paste mold and direct-press processes in a glassware forming machine including single or multiple machine sections each having single or multiple-cavity, comprising: forming a parison in an inverted orientation, into a blank mold and a first transferable and open-able neck ring mold held by an inverting apparatus having a first and a second diametrically opposed arms, each arm holding a transferable and open-able neck ring mold; inverting the parison held by the first transferable and open-able neck ring mold, by rotating the first arm 180° to an upright orientation at an intermediate station, while the second arm with a second transferable and open-able neck ring mold is simultaneously placed at the parison forming station; transferring the first transferable and open-able neck ring mold holding the parison in an upright orientation, from the intermediate station, to a blow mold station, by a transference apparatus; releasing the first parison into a blow mold, and turning back the first transferable and open-able neck ring mold empty to the first arm of the inverting apparatus, at the intermediate station to be placed again at the parison forming station by rotating the first arm additional 180°, completing a 360° turn, while the second arm reaches to the intermediate station; blowing the parison into a blow mold to form a finished article; and transferring the finished article in an upright orientation, once the blow mold is opened, by a take out apparatus, to place it at a dead plate or at a carrying conveyor.

       192 . An equalizing mechanism for a baffle apparatus having three baffle heads or a blow head apparatus including three blow heads, to place said baffle heads or blow heads over blank molds or over blow molds, respectively, with a balanced force, in a glassware forming machine, said equalizing mechanism comprising: holding means for housing and holding equalizing components; carrier means, mounted on the holding means, carrying the baffle heads or the blow heads; and rocker means in which the carrier means are mounted, to provide an up and down positive scotch yoke-like movement to said carrier means and said baffle heads or blow heads. 
   
   
       193 . The equalizing mechanism of  claim 192 , wherein the holding means comprising an equalizer carcass including a horizontal holding body having a central bore for distributing cooling and operating fluid or allow a vacuum to be applied; a horizontal conduit centrally integrated to the horizontal holding body, having a first end including a first housing, an intermediate portion having a central housing and a second end opposed to the first end, including a second housing, said first housing, central housing and second housing being positioned co-lineally to the center of each blank mold or blow mold, and each housing including a pair of opposed depending holding skirts, a central one of said depending holding skirts including a hemi-bore, cooperating with a pair of clamps, each having a hemi-bore, completing a holding bore for receiving a holding pin. 
   
   
       194 . The equalizing mechanism of  claim 192 , wherein the carrier means comprising a top opened central carrier, and a first and a second top closed lateral carriers, each carrier to be placed at each housing of the holding means, and comprising a vertical tubular conduit, each having a transversal bore coinciding with the horizontal conduit of the holding means, for fluid communication, the central vertical tubular conduit including a flow compensator to equalize the fluid regarding the other vertical tubular conduits, a sealing metallic piston ring for sealing the housings of the holding means, to avoid leakage of cooling and/or operation fluid, and two pairs of opposed horizontal retention flanges, for providing up and down positive scotch yoke-like movements for equalizing forces and controlling differences of height of blank molds or blow molds, and defining a flat retention portion between them, at each opposite side of the tubular conduit to be retained by the rocker means; and a perpendicular, horizontal holding ring each having a peripheral “C” shaped flange including cuttings for the introduction of a respective baffle head or blow head which remain locked when turning into the peripheral “C” shaped flange, and a housing for a retractable retaining piston, to avoid unlocking of the baffle heads or blow heads. 
   
   
       195 . The equalizing mechanism of  claim 192 , wherein the rocker means comprising: a first elongated rocker arm for holding a first carrier, comprised by a pair of similar opposed parallel elongated arms integrally retained, by a first rounded end, by a horizontal upper integral wall and, at a second rounded fork end, by a vertical integral wall defining a holding fork for retaining the first carrier providing the up and down positive scotch yoke-like movement; a first bore passing through both first elongated arm and second elongated arm at the first end, and a second bore passing also through both first elongated arm and second elongated arm, at an intermediate portion thereof, for mounting said first carrier; and a second short rocker arm retaining a central carrier and a second carrier, comprised by a pair of parallel arms, integrally joined at an intermediate portion by an intermediate integral wall, having a bore passing throughout the integral wall, defining a first rounded fork end and a second rounded fork end, for retaining a central carrier and second carrier and provide them an up and down positive scotch yoke-like movement.
