GLASS FORMING METHOD WITH INDIVIDUALLY CONTROLLED PLUNGER END POSITIONS
A glass forming machine and a method for manufacturing formed glass parisons. A glass forming machine includes a blank side for forming parisons from gobs of molten glass. The blank side includes a plunger and a blank mould. The plunger can be moved into the blank mould up to an end position. The plunger can be moved out of the blank mould up to a start position. The glass forming machine includes a glass feeding device which is configured to bring a gob of molten glass into the blank mould. The glass forming machine includes a measuring device which is configured to measure the end position of the plunger. The glass feeding device is configured such that the size of a gob of molten glass depends on the end position previously reached during operation. Parisons of good quality can be produced with a bigger tolerance of mould volumina.
Gob distributor for a machine for forming glass articles
A gob distributor for a glassware forming machine includes: a housing; an arcuate or straight scoop located above the housing, having an upper end aligned at all times with an orifice of a feeder, and which radially moves so that its lower end coincides with the upper ends of straight fixed channels of a forming machine; an independent support structure connected by each scoop; at least one first shaft vertically placed within the housing to rotate on its own axis, including a first gear section; at least one second shaft horizontally or vertically placed within the housing to rotate on its own axis, including a second gear section, each first gear section and each second gear section are coupled together to form a housing gear; and at least one motor coupled at each end of each second shaft to simultaneously move the supporting structures and scoops, radially.
MOLTEN GLASS FEEDING AND MOLDING
A method of providing glass from a glass melting furnace to at least one mold, including providing an uninterrupted glass communication path from an outlet of the glass melting furnace to the at least one mold, and pressurizing the path at a location downstream of the outlet to move molten glass into the at least one mold. A related system, apparatus, and molding equipment are also disclosed.
METHOD AND A SYSTEM FOR OBTAINING INFORMATION ABOUT FRICTION BETWEEN A HEATED GLASS GOB AND AT LEAST ONE GUIDE TROUGH AS WELL AS A SYSTEM FOR MANUFACTURING A GLASS PRODUCT
Method for obtaining information about friction between a heated glass gob and at least one guiding trough through which the glass gob is transported to a mould for forming a glass product from the glass gob using the mould, wherein the glass product is manufactured by: a. forming the heated glass gob; b. transporting the glass gob through at least one guiding trough to the mould; c. forming the glass gob into the glass product using the mould, wherein the method furthermore comprises the following steps: d. making an infrared image of an outer part surface of the at least one guiding trough along which, in use, the gob (while making contact with the outer part surface) is transported; and e. analysing the image for obtaining the information about the friction between the heated glass gob and the outer part surface of the at least one guiding trough along which the glass gob while making contact with the outer part surface is transported.
GLASS MANUFACTURING APPARATUS AND METHODS
A method of controlling a flowrate of molten material at a downstream location in a glass manufacturing process can include mixing the molten material at an upstream location positioned upstream from the downstream location relative to a flow direction of the molten material with a shaft including a plurality of protrusions. The method can also include measuring a torque of the shaft, measuring a level of the molten material at the upstream location, and calculating a viscosity of the molten material at the upstream location based on the measured torque and the measured level. In addition, the method can include estimating the flowrate based on the calculated viscosity, and controlling the flowrate at the downstream location based on the estimated flowrate.
APPARATUS AND METHOD FOR CONTROLLING AN OXYGEN CONTAINING ATMOSPHERE IN A GLASS MANUFACTURING PROCESS
Methods for reducing the oxygen concentration in an enclosure including a platinum-containing vessel through which molten glass is flowing are disclosed. The methods include injecting hydrogen gas into an oxygen-containing atmosphere flowing between the enclosure and a reaction chamber. The atmosphere is heated with a heating element in the reaction chamber, whereupon oxygen in the oxygen-containing atmosphere reacts with the hydrogen. In other embodiments, the hydrogen gas and oxygen-containing atmosphere can be exposed to a catalyst comprising platinum positioned in the reaction chamber.
Glass manufacturing apparatuses and methods for operating the same
In embodiments, a method for operating a glass manufacturing apparatus may include heating a delivery conduit with resistive windings positioned around an exterior surface of the delivery conduit, the delivery conduit extending between a mixing vessel and a delivery vessel. The method may also include injecting electric current through the delivery conduit while heating the delivery conduit with resistive windings and prior to flowing molten glass through the delivery conduit thereby increasing a temperature of the of the delivery conduit, wherein an input heat flux into the delivery conduit is greater than an output heat flux away from the delivery conduit prior to flowing molten glass through the delivery conduit.
MULTIVARIABLE VERTICAL GLASS DISTRIBUTION CONTROL USING SOFT SENSOR AND METHODS
Methods and systems for controlling vertical glass distribution are provided. A traversing pyrometer periodically measures a parison actual temperature after the parisons exit a blank mold. The thermal camera takes a thermal image of each glass container after the glass container exits the blow mold. A vertical glass signature extraction module extracts a vertical glass distribution signature. A parison temperature estimator determines a parison estimated temperature for each vertical glass distribution signature obtained based on the vertical glass distribution signature, a most recently measured parison actual temperature and a parison stretch time. A parison temperature summer compares the parison estimated temperature to a parison set point temperature to determine a parison temperature error. A parison temperature control controls a blank mold contact time based on the parison temperature error.
Confirming compliance with a configuration
Confirming compliance with a configuration includes: receiving information about a fixture, where the information includes a specified configuration of items to be displayed on the fixture; generating a display using the information, where the display depicts the specified configuration; presenting the display using a graphics system of a computing device; receiving an image depicting an actual configuration of the fixture; associating metadata with the image, where the metadata includes searchable data that distinguishes the fixture from at least some other fixtures of like type; sending the image, along with the metadata, over a network to a server that is remote from the computing device; and in a case that the specified configuration substantially matches the actual configuration, sending, along with the image and the metadata, a message indicating that the fixture is in compliance with the specified configuration.
