  • Patent number: 10494287
    Abstract: A device for manufacturing hollow glass articles, namely an IS machine, includes a plurality of adjacent stations (3), which form a row and respectively accommodate at least one blank mold that encloses a mold cavity, the inner walls of which have to be coated with a lubricant in accordance with a defined spray pattern by means of a spraying device (8) that can be moved along the row during the course of the glass forming operation. In order to ensure a reproducible spray pattern, a calibration station (10) is provided and equipped with a test mold (12), wherein the spraying device (8) can be displaced up to an inspection position, in which it is arranged opposite of the calibration station (10), in order to verify the correct function of a lubrication process based on a spray pattern in the test mold (12) and, if necessary, to correct the lubrication process.

  • Patent number: 10252929
    Abstract: A device for manufacturing hollow glass article consists of a plurality of modular stations that, among other things, comprise blank molds and finish molds, wherein a housing is provided and can be displaced along a blank mold side in order to carry out at least control and servicing functions, and wherein said housing is formed by a key-like structure that is open in the direction of the blank mold side and serves as a carrier for at least one manipulation element consisting of multiple sections. On its free end, this manipulation element carries a tool or a device that is ready for use after it has reached the respective station. The shielding effect of the housing reliably protects an operator side against accidents due to inadvertent interventions in machine motion sequences.

  • Patent number: 9898813
    Abstract: The invention relates to a method for detecting defects in the walls of hollow glass items that rotate about their longitudinal axis during inspection, which method, in one form, is characterized by the production of an image series (4) that is binarised using a grey-scale value threshold image (5), wherein the threshold values of the threshold image (5) are measured differently according to the fixed positions of radiation-receiving elements used to display images. The images of the image series (10) formed by binarising the original image series (4) are combined in a histogram (6) that locally adds up the frequency of an occurrence of, inter alia, defect pixels representing static reflections within the sensor regions of the image series (10).

  • Patent number: 9790118
    Abstract: A valve assembly (1) which is intended for differentiated individual control of the movement mechanisms of an IS machine and can therefore be used in a modular manner consists of a valve support (2?) and a head part (22) which supports two pilot control valves (3, 5), two safety valves (4, 6) and two switching valves as one assembly. By way of actuation of the safety valves (4, 6), the feed of control air to the switching valves can be interrupted, which switching valves are assigned, for example, to the opening movement and the closing movement, respectively, of a closing cylinder which is assigned to a preform. 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.

  • Patent number: 9458042
    Abstract: In order to achieve reproducible operating parameters of the shaping process of an I.S. glassware forming machine, a central control of all blowing and cooling air flows is proposed, in which in accordance with sections a volume flow of the cooling air including the inlet-side and outlet-side temperatures thereof are measured by means of a measuring device (51, 52) and a heat loss which is associated with the section is ascertained. The heat thus removed in sections is compared with standard values, wherein in the event that tolerance zones are exceeded a variation of the volume flow is initiated by the actuation of restrictors (53, 54). All of the sections of the glassware forming machine which are intended for passage of cooling air are monitored in this way, namely on the basis of a determinable heat loss, so that uniform cooling conditions, which are adapted to a mathematical model, and in this respect a reproducible product quality are achieved.

  • Patent number: 9403709
    Abstract: In a method for controlling the process parameters of a machine for producing hollow glass articles, the shape of the produced hollow glass article is measured online by means of at least one camera immediately after its shaping. Deviations from a reference shape are detected, and these deviations are used as the basis of the control. The control is a storage medium that contains a mechanical model describing the functional correlation between a certain pattern of a deformation of the hollow glass article and an adjustment of process parameters. An intervention in the adjustments of process parameters is carried out in accordance with the type of deformation detected.

  • Patent number: 9272939
    Abstract: A dead plate arrangement for a glass forming machine is characterized by a housing (33) which is bordered on the upper side by a dead plate (1) which is divided into fields (16, 16?, 16?) intended for putting hollow glass articles to be cooled thereon, wherein to each field, a dynamic pressure chamber (3) is allocated which is connected to a supply air chamber (4) via a valve (9), and wherein the supply air chamber (4) is connected to a cooling air supply via a valve (5). The valves (5, 9) are continuously controllable between an opening position and a closed position so that the pressure can be set for each of the dynamic pressure chambers (3), and therefore the cooling capacity of each of the fields (16, 16?, 16?) can be set individually depending on the properties of the hollow glass article to be cooled.

  • Patent number: 8869557
    Abstract: The invention relates to a method for supplying lubricating points of an I.S. glassware forming machine, wherein a used lubrication system comprises a plurality of lubricant metering devices (29) that are provided to output lubricant to a plurality of lubricating points, that are to be lubricated, of the glassware forming machine and are allocated in each case to one of several lubrication circuits (23-28). The lubricant metering devices of a respective lubrication circuit simultaneously output a predetermined amount of lubricant in each case cyclically with a time interval allocated to the lubrication circuit. The lubricant metering devices are allocated to lubrication circuits in dependence upon temperatures that have been measured in direct proximity to lubricating points, and are allocated such that the temperatures of the lubricating points of a lubrication circuit are within a predetermined temperature range.
