The disclosure includes a process and an apparatus for delivering a gob of molten glass into a blank mold. The apparatus includes a loading funnel holder that defines at least one opening, and a split loading funnel rotatably carried by the funnel holder. The split loading funnel includes two or more individual funnel segments that together provide an outlet of the funnel having an exit plane, each of the individual funnel segments having a lower portion that includes a concave interior guide surface. The two or more individual funnel segments are coupled together so that the interior guide surfaces of the individual funnel segments cooperate to define a guide passage extending along a longitudinal axis and terminating at the outlet.

A system and method for coating glass gobs with a liquid-based lubricating dispersion during their drop to blank glass container molds which provides sufficient lubrication to the glass container molds without requiring swabbing of the glass container molds. The lubricating dispersion is sprayed onto hot glass gobs as they fall from the gob supply system prior to their distribution by the gob distribution system into blank molds. The lubricating dispersion coats the falling glass gobs to lubricate the glass gobs as well as the molds.

A glass gob distributor for delivering gobs of molten glass to sections of a glassware forming machine, in accordance with exemplary embodiments of the present disclosure, includes at least one electric motor, a ball screw coupled to the electric motor and a carriage slidable on a carriage shaft and coupled to the ball screw. At least one gear rack is coupled to the carriage and at least one scoop is coupled to the gear rack for rotation around a scoop axis as a function of linear motion of the gear rack and the carriage. A pair of slides are slidably disposed on opposite sides of the carriage and are disconnected from the carriage. A pair of fluid cylinders are disposed adjacent to the slides. The fluid cylinders are responsive to an absence of power at the electric motor for pushing the centering slides toward each other to abut and slidably position the carriage on the carriage shaft, the gear rack and the at least one scoop at a home position. In exemplary embodiments of the disclosure, a plurality of scoops are coupled either to individual associated electric motors through associated gear racks, carriages and ball screws, or are coupled to a single electric motor through one or more gear racks, a single carriage and a single ball screw.

An inclined trough assembly (10) for conveying, by gravity, formable gobs of glass at an elevated temperature to a section of a glass container forming machine of the I.S. type, the trough assembly having a trough member (12) configured, in cross-section, generally corresponding to that of an upwardly facing V and a manifold (14) at least partly underlying the trough member and having a configuration, in cross-section, generally corresponding to that of an upwardly facing U. The trough member 12 is inserted into the manifold partly to the bottom thereof, and the manifold has a compressed air inlet (14a) for receiving compressed or fan air to flow along the manifold in cooling contact with the trough member to cool the trough member and thereby reduce the coefficient of friction between the gobs of glass flowing through the trough assembly and the trough member thereof. The trough member has an opposed pair of legs (12a, 12b) joined at the bottoms thereof in a bight (12c), the upper free ends of the legs being spaced apart a greater distance than the width of gobs of the largest size in a wide range of sizes of gobs to be passed through the trough assembly, the bight having a radius greater than the width of gobs of the smallest size in the range of sizes. The trough member has a plurality of apertures (12e) extending therethrough, to permit compressed or fan air flowing in the manifold to flow into the trough member, to thereby further cool the trough member and at least partly levitate the gobs in the trough member to further reduce frictional forces acting on the gobs as they flow through the trough assembly.
摘要:
A glassware forming machine system includes an individual section glassware forming machine having a plurality of sections, each with at least one blank mold, and a gob distributor for distributing molten glass gobs to the blank molds of each machine section in sequence. The molten glass gobs are delivered to the blank molds of each section through deflectors on which the glass gobs slide to each blank mold. At least one liquid coolant passage is integral with each deflector, and the several coolant passages for the entire machine are connected in parallel between source and return liquid coolant manifolds. Variable flow control valves are individually connected between each liquid coolant passage and the return manifold for controlling flow of liquid coolant through the passages and thereby balance temperatures among the parallel gob deflectors. In this way, all of the gob deflectors are maintained at the same temperature, which improves uniformity of temperature and timing of gob delivery to the blank molds of the several machine sections.

An I.S. machine is disclosed wherein the blow molds are held open during a preheat blank mold mode of operation and the neck ring arms of an invert and neck ring assembly are rotated to an acute angle and opened to release held parisons. A cullet chute is defined in the section frame from a location below the invert of the assembly towards the blow molds to collect the parisons which are delivered by a parison deflector.
