In order to permit more effective cooling in comparison to the prior art, in particular in its floor area, of a hollow glass article () standing upright on the base () of a setting plate () provided with transcurrent orifices (&#x2033;) forming a cavity () between a base () and the facing surface of the setting plate () of the standing surface (&#x2033;), it is proposed to utilize a part of the orifices () situated inside the standing surface (&#x2033;) for the supply of cooling air into the cavity (), and to utilize the remaining orifices (') inside the standing surface (&#x2033;) only for the extraction of cooling air from the cavity (). By configuring the orifices (&#x2032;) that are utilized in each case for the supply and extraction of cooling air into and out of the cavity () so that they are at least approximately cross-sectionally identical, a throughput of cooling air through the cavity () and thus the available cooling performance can be varied within broad limits, but in the absence of an adverse effect on the stability of the hollow glass article () or a resulting risk of uncontrolled positional displacements on the setting plate ().

Setting plate arrangement

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.

A device for transferring an object from a dead plate of an Individual Section glass-forming machine to a conveyor belt is disclosed. The device includes a first shaft rotatable about an axis. A housing is attached to the first shaft. A carrying arm is slidably mounted on the housing and has a finger at one end for engaging the object. A guide piece having a groove is attached to the other end of the carrying arm. A crank arm engages the groove. The crank arm is connected to a second shaft coaxial with the first shaft. The shafts rotate independently of one another. Each shaft has its own drive unit. Rotation of the first shaft rotates the carrying arm about the first axis and rotation of the second shaft causes sliding motion of the carrying arm along its longitudinal axis.

Method and apparatus for pressing a parison. A parison mold is composed of neck tool halves and parison mold halves. A gob of molten glass had first been introduced through an upper loading orifice into a cavity of the parison mold, while a pressing plunger was located in a lower loading position. An assembly consisting of a pressing element, a guide sleeve and a piston-cylinder unit was introduced into the loading orifice. Subsequently the pressing plunger was raised from its loading position into the illustrated upper end operating position until its annular end face had moved into position against a stop surface of the neck tool. Following the preliminary pressing process a neck chamber in the cavity is still free from molten glass. It is only at this point that the pressing element exerts pressure on a base of the parison which is being produced. The molten glass is also pressed into the hitherto still free neck chamber of the cavity. The finish-pressing process of the parison is thus completed and the parison mold can be opened for the purpose of transferring the parison into a finish-forming station.

An arrangement for adjusting the mass of gobs of thermoplastic material, especially molten glass, which are deformed in a positive manner in the mold of a molding machine by means of a pressing member which penetrates into the gobs. A distance transducer mechanically detects the maximum depth of penetration reached by the pressing member during each molding-machine operating cycle. The distance transducer is connected with a metallic actuating element for a differential transducer, at whose output is produced an electrical signal proportional to the maximum penetration depth reached, this signal being applied to an automatic regulating circuit which adjusts the setting of a dosing structure which controls the mass of the gobs. The regulating circuit includes, at the output of the differential transformer and connected one after the next, a measurement transducer, a maximum-value storage, a sample-and-hold circuit, a summing junction, a PI- or PID-regulator and an adjusting motor which drives an adjusting member for the dosing structure, as well as a feedback transducer. The feedback transducer is connected to the PI- or PID-regulator via a rotary-angle-to-voltage converter. A control and display panel is connected to a control logic circuit, the latter connected to the maximum-value storage and to the sample-and-hold circuit, the control logic circuit receiving a machine synchronization signal once per machine operating cycle. A desired-value potentiometer furnishes a desired-value voltage representing the optimum penetration depth for the pressing member, this voltage being applied to the summing junction. A weighting circuit can be provided to take into account the different maximum diameters of different pressing members which may from time to time be used. The feedback transducer is automatically returned to a middle angular setting thereof. The distance transducer can be constructed in several different ways, disclosed.

Each station has a push-off unit which transfers glass articles produced at such station onto a common outfeed conveyor. Each push-off unit comprises a cylinder-piston unit mounted for swinging movement on a vertical swing shaft, the piston thereof carrying a push-off arm. The push-off arm extends and engages the articles to be transferred, the cylinder swings towards the belt transferring the article, and the push-off arm retracts and the cylinder swings back. The push-off units of the plural stations are activated sequentially, in correspondence to the sequence in which glass gobs are fed into the respective machine stations. Plural electric motors are provided, one per station, and the swing motion of the push-off unit is generated by the respective electric motor. The rotation of each electric motor is controllable, by open- or closed-loop control, independently of the other electric motors. The operator selects the sequence in which the electric motors are to be activated. A common or shared desired-rpm voltage is applied to all electric motors, sequentially. The electric motors drive the push-off units through respective crank and rocker mechanisms.
