BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is the US national phase of PCT application PCT/EP96/00017 filed 4 Jan. 1996 with a claim to the priority of German application 195 01 762.5 itself filed 27 Jan. 1995.
FIELD OF THE INVENTION
The invention relates to a channel arrangement for conveying a glass gob from a gob distributor to a mold of a glass machine with a central trough whose inlet is connected to an inlet trough of the gob distributor and which is inclined downward from its inlet to its outlet and a deflecting trough whose inlet is connected to the outlet of the central trough and whose outlet end is generally straight and which is held so by means of an adjustable hanger on a frame part of the glass machine that the position of its outlet can be aligned with the central axis of the mold of the glass machine.
BACKGROUND OF THE INVENTION
With known such channel arrangements the smoothest possible conveying of the glass gob from the deflecting trough into the mold is sought in that the outlet of the deflecting trough is movable with the latter so that it can be brought into alignment with the central axis of the mold. As a result of the movability of the deflecting trough relative to the mold, deviations between the central axis of the outlet end of the deflecting trough and the central axis of the mold occur readily. They result in guality problems in the glass article made from the glass gob.
OBJECT OF THE INVENTION
It is an object of the invention to improve the described channel arrangement for conveying a glass gob from a gob distributor into a mold of a glass machine such that an exactly centered transfer of the glass gob from the deflecting trough of the channel arrangement is possible into the mold of the glass machine.
SUMMARY OF THE INVENTION
This object is solved according to the invention in that the outlet end of the deflecting trough is separate therefrom and is formed as a funnel. This funnel-shaped outlet end of the deflecting trough is held fixedly relative to the mold. The remaining part of the deflecting trough is made movable relative to the funnel which tapers toward the mold. As a result of its movability the central axis of the outlet region of the deflecting trough is always aligned with the central axis of the funnel or of the mold. Small deviations between the central axis of the outlet of the deflecting groove and the central axis of the funnel are eliminated by the funnel effect so that the glass gob leaves the end exactly aligned with the central axis of the funnel-shaped end fixed relative to the mold. Since this central axis is always aligned with the central axis of the mold as a result of being fixed spatially relative to the mold, the glass gob moves exactly in the desired direction into the mold. As a result there is an ideal distribution of the glass material present inside the glass gob inside the mold. In addition the end formed according to the invention insures that the glass gob is not deformed or is only slightly deformed.
An exact alignment of the central axis of the funnel-shaped separate outlet end of the deflecting trough with the central axis of the mold is achieved in a simple manner when the outlet end of the deflecting trough is held by a hanger and is adjustable on the hanger by means of two adjusters in two directions perpendicular to each other and to the central axis of the end.
To exchange the separate outlet ends it is preferable when the above-mentioned hanger is arranged on a slide that moves along a rail. In this manner for example changing of the funnel-shaped outlet end of the deflector trough is possible.
A transfer between the central trough of the channel arrangement and its deflecting trough with minimal problems and a transfer minimally impacting the quality of the glass gob is possible when the outlet of the central trough and of the inlet of the deflecting trough are interconnected by means of a connecting traverse between which and the outlet of the central trough is a ball-type swivel mount.
