Abstract: A method for operating an IS machine for producing glass containers includes: introducing a glass gob into a blank mold, producing a parison from the glass gob in the blank mold, transferring the parison into a finishing mold, actuating a vacuum valve for producing a vacuum in the finishing mold from a first actuating point in time and simultaneously measuring the evolution of the vacuum pressure, actuating a finish-blowing valve for generating a finish-blowing pressure from a second actuating point in time that is later than the first actuating point in time by a predetermined duration, such that compressed air is blown into the finishing mold from the top, and simultaneously measuring the evolution of the finish-blowing pressure and checking whether the evolution of the measured vacuum pressure and/or the evolution of the measured finish-blowing pressure has fulfilled a predetermined condition.

Abstract: 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.

The valve assembly has interfaces for connection of control and operating air and for electric connection to a machine controller. If required, the assembly which is designed in this way makes it possible to interrupt the control air in a differentiated way which is related to an individual track, in addition to simple assembly and dismantling.

Abstract: A process and a device for pushing hollow glass objects off a glass forming machine onto a moving conveyor belt are disclosed. Each hollow glass object is pushed by a push-off unit from a dead plate along a curved path onto the conveyor belt in such a way that the curved path is brought tangentially to a contact point in a movement direction of the conveyor belt. Subsequent to the contact point each hollow glass object is pushed further by the push-off unit by a further linear path portion in the movement direction of the conveyor belt as far as a release point at which the push-off unit is released from the hollow glass object. The push-off unit is then moved back to dead plate.
