摘要:
Equipment for glass container manufacturing wherein a plunger used to form a parison in a glass container forming operation is provided with a cylindrical sleeve adapted to lock the plunger base end against a support member firmly fastened to a reciprocal piston. The sleeve is spring-loaded to hold it in operative position and permit lateral limited adjustment during operation, and may be manually elevated to facilitate quick rotative removal of installation of the plunger.
摘要:
A method and apparatus for forming a glass container in a blow-and-blow process. The apparatus includes an air flow controller having a housing defining a chamber, a piston disposed for reciprocal movement from a first position to a second position within the housing for moving a slide block therein, first and second passages extending through the slide block, a first port in the housing in flow communication with the second passage and a transducer when the piston is in its second position to create a negative air flow through the second passage and first port when a pressurized air flow is induced through the transducer to draw a vacuum beneath a gob in a blank mold to form a finish in the gob and sweep debris away from the gob and blank mold, and a second port in communication with the first passage and first port when the piston is in its first position to provide pressurized air to the gob.
摘要:
A forming plunger mechanism for glass container manufacturing of the type used in an I.S. machine and having at least one vertically-oriented cylinder containing a reciprocally-driven piston for repeatedly driving a plunger upwardly into parisons contained by a blank mould, wherein a saddle plate is provided for supporting one or more vertically-oriented cylinders. The saddle plate is adapted to accommodate on its upper surface a plurality of repositionable port blocks. Each port block has internal conduit channels with generally laterally-facing ports which operatively register with ports at the lower end of the cylinder. The conduit channels have substantially upwardly-facing openings for connection thereto with ends of hoses which serve to conduct a pressurized air stream through the port block and into the cylinder for driving the cylinder's piston in a reciprocal action and for conducting a cooling air flow through the mechanism. The port blocks may be selectively repositioned on the upper surface of the saddle plate to accommodate more than one cylinder size without disturbing the connection of the hose ends to the port blocks. Provision is made for electrical sensing within the cylinders and for completing electrical circuit connection at the cylinder's distal end as a function of installing the cylinder in its operative position. The saddle plate is provided with upper surface grooves for containing insulated conductor leads which extend from the point of connection on the underface of the distal end of the cylinder and outwardly from the lateral surface of the saddle plate.

A cartridge assembly for a blow-and-blow parison-forming machine comprises a cylindrical barrel, an annular lower stop having a central opening for accepting a piston rod and having an upwardly opening tapered recess adjacent the central opening, an annular cylinder cap having a central opening for accepting a thimble and plunger and having a downwardly opening tapered recess adjacent the central opening. The lower stop, cylinder cap, and barrel form a unit. An annular floating piston is arranged to reciprocate within the cylindrical barrel. The floating piston has a lower tapered end for at the lowermost position of the floating piston resting in the upwardly opening tapered recess in the lower stop and an upper tapered end for at the uppermost position of the floating piston resting in the downwardly opening tapered recess in the cylinder cap.
摘要:
In an individual section machine for producing glass containers from molten glass, a sliding tube-in-a-tube arrangement forms part of an internal cooling air passageway for directing a pressurized air flow to a pressing plunger. A linearly-movable piston comprising a ring-shaped base with an upwardly-projecting rod portion, is supported within a cylinder casing, and the plunger is supported on a projecting end of the rod portion. The piston has a central opening in the bore of the rod portion which merges with a longitudinal elongated thin-walled tubular member. The tubular member is disposed to define an annular space between its outer surface and the internal bore sidewall. A fixed second tubular member projects centrally upwardly from the cylinder casing's base end and into the annular space whereby linear movement of the piston causes the first tubular member to telescopically slide within the fixed second tubular member and maintain an extensible-retractable air tube structure.
