Machine to cut-off an end of a hollow glassware article

A machine to automatically cutoff one end of a hollow glassware article, said machine comprising:

• a support structure including a base and a vertical shaft having an upper end and a lower end centrally mounted on the base, and control means at the upper end of the vertical shaft to provide control and electrical energy to driving components of the machine;
• intermittent driving means, rotary mounted on the vertical shaft providing a plurality of intermittent positions corresponding to article charging, cutoff, finishing and discharging positions;
• a lower intermittent rotary table rotary mounted on the vertical shaft and coupled to the intermittent driving means to be driven thereby;
• a plurality of one-piece cutoff burners, each equidistantly mounted on the periphery of said lower intermittent rotary table, to cutoff an excess piece of a lower end of said hollow glassware article and to finish the cut-off end thereof within a cutoff cycle;
• an upper intermittent rotary table mounted on the vertical shaft and coupled to the lower intermittent rotary table to be driven thereby;
• continuously rotary driving means mounted on the lower intermittent rotary table, including a motor mounted on the lower intermittent rotary table for imparting a continuous rotary movement, a shaft retained by a bearing sleeve mounted on the upper intermittent rotary table and coupled to the motor, a driving sprocket coupled to an upper end of said shaft, and a chain coupled to the sprocket to be continuously rotated by the sprocket;
• a plurality of chuck driving means equidistantly mounted on the periphery of the upper intermittent rotary table, each chuck driving means comprising a bearing sleeve, a rotary sprocket mounted on the bearing sleeve which is coupled and continuously rotated by the chain, and a crown gear on the rotary sprocket;
• a plurality of chuck actuating and gripping means equidistantly mounted proximate the periphery of the upper intermittent rotary table and comprising a shaft gripping sleeve having an annular gear at a lower end for engaging the crown gear of the chuck driving means, a central hollow shaft slide passing through and gripped by the shaft gripping sleeve, said slide gripping sleeve having coupling means at a lower end, and vertical reciprocate means operatively coupled to the shaft gripping sleeve to downwardly move the gripping sleeve to engage the annular gear with the crown gear and thereby transmit the continuous rotary movement to the hollow shaft and its coupling means, and lift said gripping sleeve to interrupt the rotary movement to said shaft gripping sleeve;
• a plurality of chuck carrier and operating means, each comprising a central chuck operating bar slide passing through the hollow shaft of the chuck actuating and gripping means, a hollow spacer sleeve coupled to the coupling means of the hollow shaft, a chuck carrier coupled to the spacer sleeve, and a chuck operating means in the chuck carrier;
• a plurality of chuck an inner hollow cod to a chuck carrier and having an inner hollow compartment including a plurality of joint pins around the inner periphery thereof, an actuating plate slide in the hollow compartment and centrally coupled to the lower end of the chuck operating bar, and having a plurality of gripping pins and a corresponding number of gripping fingers each finger having an oblique portion having a free end coupled to a gripping pin, a middle portion coupled to a joint pin and a vertical portion including a gripping pad at its lower end, so that when the plate is at an upper position, the gripping fingers are normally closed around the upper end of a hollow glassware article and when said chuck operating bar is pushed down by a chuck actuator, pushing down the plate of the chuck retaining mechanism, the gripping fingers are consequently opened;
• and
• chuck actuator means operable at the charging position and at the discharging position, each including driving means and a vertical reciprocal member operably coupled to the driving means to momentarily open and close the gripping fingers to release a hollow glassware article while it is at a discharging position, or to grip a hollow glassware article at the charging position.
