Method and device for controlling a thermal treatment process for glass sheets
The disclosure relates to a method for controlling a glass sheet heating furnace using information describing a glass load including a plurality of glass sheets. The method includes transporting the glass sheets toward a heating furnace, before thermal treatment, photographing the glass load by a camera to obtain a camera image, sending first information of the camera image to a computer, on the basis of which the computer determines a first value of a dimension of the glass load and selects a value of at least one adjustment parameter of the heating furnace on the basis of the first value before the glass load has been transferred into the heating furnace, and reading second information by a line scanner, which is sent to the computer, on the basis of which the computer determines a second value of the dimension of the glass load.
PLUNGER ASSEMBLY FOR A GLASS MOLDING MACHINE
A plunger assembly for a glass forming machine comprises an assembly housing (6), at which a drive (17) is in contact with a drive spindle, which is supported in an axially non-displaceable manner, via an angular gear, which drive spindle, in turn, engages with a spindle nut, the spindle nut housing (18) of which is set up via an assembly (19) by interpositioning pressing force limiters for transferring the pressing force required for a forming process to two plungers (1, 2). The assembly (19) can be displaced in a non-rotatable manner along two guide columns (7, 8), which are arranged parallel to one another in a housing-fixed manner, and the spindle nut housing (18) engages with two lateral linear guides, which are also arranged in a housing-fixed manner. The connection between the assembly (19) and the spindle nut housing (18) is designed in such a way that only forces in the direction of the pressing force are transferred, so that any other forces and moments originating from the forming process are transferred to the housing, so that in particular the drive spindle is only axially stressed.
System and method for cooling moulds for a machine used to form hollow glass items
The present invention relates to mold cooling method and system for a glass container forming machine that includes at least one mold holder including mold halves that are movable between a closed mold position for forming the glass article and an open mold position for releasing said article, each of the mold halves having axial passages for cooling each of the mold halves. A support structure having a fixed upper support section and a movable support section. Means for providing a cooling flow are coupled in coincidence with a series of openings in the movable support section. A cooling flow distributor located above the movable support section, the cooling flow distributor having a lower section in coincidence with each of the openings of the movable support section for the passage of the cooling flow and, a upper section in coincidence with each of the axial passages of each of the halves of each mold, the cooling flow distributor being movable between the closed mold position and the open mold position.
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.

Arrangement for realizing the vacuum operation in the moulding process of a glass moulding machine
For the monitoring of the application of a vacuum to the finished moulds (1, 2) of a glass moulding machine, in particular of an I. S. machine, an arrangement is proposed which is composed of a vacuum sensor (13, 14), which vacuum sensor is arranged in a vacuum line (5, 6) which charges the finished mould (1, 2) and which vacuum sensor is designed for pressure measurement and detects a pressure value, which pressure value is transmitted by way of a microcontroller (15, 16) of an I. S. machine controller (22) by way of which, in a manner dependent on the measured value, a hollow glass article can be identified as being defective and rejected. The arrangement permits automated monitoring of the vacuum operation and a lessening of the burden on operating personnel, and serves for the automated assurance of product quality.
