Apparatus for spraying at a spraying station aligned with a continuously moving conveyor belt
| Details |
Inventors: Pietrowski, Michael L.; Norlin, Gordon D.; Mohr, Thomas J.; Williams, Charles R.; Haug, Thomas J.; Herrmann, John W.;
Assignee: Anchor Hocking Corporation (Freeport, IL)
Primary Examiner: Lacey; David L.
Assistant Examiner: Griffin; Steven P.
Attorney, Agent or Firm: Baker & McKenzie
A spraying apparatus having a continuously moving conveyor belt which brings a vessel rim down to a spraying station, arrests movement of the vessel and aligns it with a vacuum gripping head, grips the vessel bottom and lifts and presents the vessel to a sprayer, rotates the vacuum gripped vessel rapidly to apply a plurality of thin layers of coating, and returns the coated vessel to the conveyor and releases the grip on the vessel so that the continuously moving conveyor can discharge the coated vessel from the spraying station. |
|
DETAILED DESCRIPTION We claim: 1.
Apparatus for applying a coating to a vessel, said apparatus including a continuously operating conveyor which conveys a vessel to be coated to a spraying station vertically aligned with the conveyor, means for arresting the forward movement of the vessel at the spraying station while maintaining the vessel in sliding contact with the conveyor as the conveyor continues to operate, means for breaking physical contact between the vessel and the conveyor, means for presenting said vessel to the spraying station in an inverted position following separation of the vessel from the conveyor, means for spraying the vessel positioned and arranged in said spraying station, means for rotating the vessel at a high rate of speed at the spraying station whereby a coating applied by the spraying means consists of a plurality of layers, and means for re-contacting the coated vessel with the continuously operating conveyor whereby the coated vessel is discharged from the spraying station.
2.
The apparatus of claim 1 further including means for positioning the vessel after its movement is arrested so that the vessel is accurately presented for engagement with the means for presenting.
3.
The apparatus of claim 1 further including an exhaust system at the spraying station consisting of a localized exhaust system and a general exhaust system.
4.
The apparatus of claim 3 wherein the localized exhaust system has an exhaust path positioned and arranged to be adjacent the vessel.
5.
The apparatus of claim 4 wherein the localized exhaust system is positioned and arranged to entrap overspray.
6.
The apparatus of claim 5 wherein the localized exhaust system and the general exhaust system discharge through a common conduit.
7.
The apparatus of claim 1 wherein the means for presenting the vessel to the spraying station includes vacuum means arranged to hold said vessel while said vessel is out of contact with the continuously moving conveyor.
8.
The apparatus of claim 7 wherein the means for presenting the vessel to the spraying station further includes means for rotating the vacuum means as well as the vessel at the spraying station whereby said vessel and said vacuum means rotate as a unit at the spraying station
