Ultra high speed bottle coating process

Claim 2

An ultra high speed coating process for spray coating about 90 to 100 suspended bottles per minute without wobble of the suspended bottles during the spray coating operation and without appreciable bottle breakage, each of which bottles has a dimple centrally located in the bottom of the bottle, which comprises sequentially and synchronously: (1) unpacking the bottles from cartons at a bottle unpacking station into upright multi-files and conveying and directing said multi-files of bottles into single file onto a first single file bottle belt conveyor, (2) conveying said single file of bottles in an upright position on said first single file bottle belt conveyor from said bottle unpacking station to a bottle loading station, (3) loading the upright bottles by their finish from said first single file bottle belt conveyor into bottle chucks carried by an aligned and synchronized overhead chuck conveyor at a bottle loading station, (4) engaging the bottle bottom dimples with engageable stabilizing pivot pins carried by a bottle bottom stabilizing conveyor, said pivot pins being in synchronized parallel alignment and registration with the bottle chucks, (5) rotating and spray coating the sides and bottoms of the upright bottles at least once while suspended vertically from said overhead chuck conveyor and stabilized by said bottle bottom stabilizing conveyor, both conveyors traveling through at least one bottle rotating and spray coat station, the bottles being spray coated at an ultra high speed of about 90 to 100 bottles per minute, (6) disengaging the stabilizing pivot pins from the bottle bottom dimples after the upright bottles exit from said at least one bottle rotating and spray coat station, (7) heat drying the bottoms of the coated bottles while suspended vertically from said overhead chuck conveyor traveling through a bottle bottom dryer, (8) unloading the coated bottles in single file upright position from said overhead chuck conveyor onto a second aligned and synchronized single file bottle belt conveyor at a bottle unloading station, (9) conveying the single file of upright coated bottles on said second single file bottle belt conveyor from said bottle unloading station to a multi-file bottle stacking station, (10) stacking said upright coated bottles at said multi-file bottle stacking station from said second single file bottle belt conveyor into multi-files onto a conveyor belt passing through a curing oven, (11) curing and cooling the multi-files of upright coated bottles while passing through a curing oven having heating and cooling sections, and (12) packing the cured and cooled coated bottles into cartons at a bottle packing station.

Claim 3

An ultra high speed coating process for spray coating about 90 to 100 suspended bottles per minute without wobble of the suspended bottles during the spray coating operation and without appreciable bottle breakage, each of which bottles has a dimple centrally located in the bottom of the bottle, which comprises sequentially and synchronously: (1) unpacking the bottles from cartons at a bottle unpacking station into upright multi-files and conveying and directing said multi-files of bottles into single file onto a first single file bottle belt conveyor, (2) conveying said single file of bottles in an upright position on said first single file bottle belt conveyor from said bottle unpacking station to a bottle loading station, (3) loading the upright bottles by their finish from said first single file bottle belt conveyor into bottle chucks carried by an aligned and synchronized overhead chuck conveyor at a bottle loading station, (4) engaging the bottle bottom dimples with engageable stabilizing pivot pins carried by a bottle bottom stabilizing conveyor, said pivot pins being in synchronized parallel alignment and registration with the bottle chucks, (5) rotating and spray prime coating the sides and bottoms of the upright bottles while suspended vertically from said overhead chuck conveyor and stabilized by said bottle bottom stabilizing conveyor, both conveyors traveling through a bottle rotating and prime coat spray booth, (6) drying the prime coated bottles suspended vertically from said overhead chuck conveyor and stabilized by said bottle bottom stabilizing conveyor, both conveyors traveling through a prime coat dryer, (7) rotating and spray top coating the sides and bottoms of the upright bottles while suspended vertically from said overhead chuck conveyor and stabilized by said bottle bottom stabilizing conveyor, both conveyors traveling through a first bottle rotating and top coat spray booth, (8) rotating and spray top coating the sides of the upright bottles while forwardly and reversely rotating the bottles suspended vertically from said overhead chuck conveyor and stabilized by said bottle bottom stabilizing conveyor, both conveyors traveling through a second bottle rotating and top coat spray booth, the bottles being spray coated at an ultra high speed of about 90 to 100 bottles per minute in spray coating steps (5), (7) and (8), (9) disengaging the stabilizing pivot pins from the the bottle bottom dimples after the upright bottles exit from said second bottle rotating and top coat spray booth, (10) heat drying the bottoms of the coated bottles while suspended vertically from said overhead chuck conveyor traveling through a bottle bottom dryer, (11) unloading the coated bottles in single file upright position from said overhead chuck conveyor onto a second aligned and synchronized single file bottle belt conveyor at a bottle unloading station, (12) conveying the single file of upright coated bottles on said second single file bottle belt conveyor from said bottle unloading station to a multi-file bottle stacking station, (13) stacking said upright coated bottles at said multi-file bottle stacking station from said second single file bottle belt conveyor into multi-files onto a conveyor belt passing through a curing oven, (14) curing and cooling the multi-files of upright coated bottles while passing through a curing oven having heating and cooling sections, and (15) packing the cured and cooled coated bottles into cartons at a bottle packing station.
