Claims
- 1. A delivery apparatus for transporting gobs of molten glass from a gob feeder into molds of at least one glassware forming machine, comprising:
- a curved scoop for catching a gob coming from the gob feeder and directing the gob downward at an angle;
- a trough which is approximately linear and downward sloping, said trough having an upper end for receiving the gob and a lower end, and said trough being articulately mountable relative to the glassware forming machine at the trough upper end;
- an setting device for raising and lowering the lower end of said trough;
- a curved deflector for receiving the gob coming from the trough and deflecting the gob in a downwards path coaxial with a longitudinal axis of a mold;
- a setting device for adjusting said deflector in infinite direction in a plane perpendicular to the longitudinal axis of the mold for aligning said deflector with said mold;
- wherein the setting device comprises at least one coupling member carrying the deflector;
- wherein each said coupling member is rotatable to allow rotational movement of each said coupling member and said deflector about an axis parallel to the longitudinal axis of the mold; and
- wherein each said coupling member is adjustable in a plane perpendicular to the longitudinal axis of the mold.
- 2. A delivery apparatus according to claim 1 including a strut for each said coupling member and wherein each said coupling member is displaceable lengthwise on said strut in a plane perpendicular to the longitudinal axis of the mold, and each said strut is rotatable about a first axis which is fixed relative to the glassware forming machine and which is parallel to the longitudinal axis of the mold.
- 3. A delivery apparatus according to claim 2 wherein each said coupling member is fixed to a threaded sleeve which is displaceably mounted for lengthwise movement on the strut, and an axially fixed first threaded spindle engages a thread of the threaded sleeve.
- 4. A delivery apparatus according to claim 3 having two coupling members for the deflector, said coupling members being spaced from one another and aligned, and wherein each strut is fixed on a common column rotatable about the first axis, and wherein each said first threaded spindle of the coupling members is connected to one another by a gear means.
- 5. A delivery apparatus according to claim 2 wherein a nut is mounted on the strut spaced from the first axis, said nut being rotatable about a second axis which is parallel to the first axis, and wherein an axially fixed second threaded spindle extends transversely to a connecting line between the first and second axes and perpendicular to the second axis and engages in a threaded bore in the nut.
- 6. A delivery apparatus according to claim 1 wherein the curvature of the deflector defines a surface of the deflector that is part of a quarter ellipse, and wherein, at a lower end of the deflector, a minor half axis of the quarter ellipse lies horizontal.
- 7. A delivery apparatus according to claim 1 wherein the curvature of the deflector defines a surface of the deflector that is a part of a quarter circle, and wherein, at a lower end of the deflector, a tangent to the quarter circle is coaxial with respect to the longitudinal axis of the mold.
- 8. A delivery apparatus according to claim 1 wherein the curvature of the deflector defines a surface of the deflector which is first part of a quarter circle and thereafter part of a quarter ellipse, and wherein, at a lower end of the deflector, a minor half axis of the quarter ellipse lies horizontal.
- 9. A delivery apparatus according to claim 8 wherein the quarter circle merges with the quarter ellipse defined by said deflector from outside the quarter ellipse.
- 10. A delivery apparatus according to claim 1 wherein a path of movement of the gob in the trough merges tangentially into a path of movement of the gob in the deflector.
- 11. A delivery apparatus according to claim 1 comprising more than one said scoop, more than one said trough, and more than one said deflector for use with multiple gob operation wherein more than one said gob is fed approximately simultaneously in said glassware forming machine, wherein the number of said scoops, troughs, and deflectors correspond to the number of gobs fed approximately simultaneously.
- 12. A delivery apparatus according to claim 1 further comprising a slide member arranged between a lower end of said scoop and said upper end of said trough for conducting the gob from said scoop to said trough, said slide member being fixedly supported and remaining stationary relative to the glassware forming machine and having a downwardly inclined upper slide surface for the gob.
- 13. A deliver apparatus according to claim 12 further comprising a slide unit having a plurality of said slide members connected to one another and wherein all said slide members are disposed to receive gobs from said scoop.
- 14. A delivery apparatus according to claim 13 wherein said slide unit is connected to a holding device, and said holding device is fixedly mounted relative to said glassware forming machine.
- 15. A delivery apparatus according to claim 14 further comprising:
- a setting gauge capable of being connected to said holding device; and
- a gob distributor having said scoop and which is adjustable relative to said setting gauge when said gauge is connected to said holding device, and which is fixedly mountable relative to said glassware forming machine.
- 16. A delivery apparatus according to claim 12 wherein a slide channel guiding the gob is provided in the upper sliding surface of said slide member to guide the gob, and wherein said slide channel lies in a common vertical plane with said scoop when said scoop is positioned to deliver the gob and also in a common vertical plane with said trough.
- 17. A delivery apparatus according to claim 12 further comprising a first gap between the lower end of said scoop and an upper end of said slide member, and a second gap between a lower end of said slide member and said upper end of the trough.
- 18. A delivery apparatus according to claim 12 further comprising first and second steps perpendicular to a path of movement of the gob, said first step being at said lower end of said scoop relative to an upper end of said slide member, and said second step being at a lower end of said slide member relative to said upper end of said trough.
- 19. A delivery apparatus according to claim 1 wherein an internal surface of the scoop has, at an upper end of said scoop, a downwardly narrowing, tapered funnel region which is contacted first by the gob, and wherein the funnel region includes a bottom having a tangential transition to a part-circular region of the internal surface of the scoop.
- 20. A delivery apparatus according to claim 1 wherein said trough is mountable to the glassware forming machine at the upper end of said trough by means of a universal joint and wherein said deflector includes a chute at its upper end, the lower end of said trough extends into said chute with freedom for movement in a vertical plane and secured against rotation about its longitudinal axis.
