4 Claims.
This invention relates to a cooling device which is mainly'designed for cooling cartons. the present application being a division of that led by me on March 11, 1938, Serial No. 195,387.
The general object of the present invention is to provide a chamber into which the articles, such as cartons coated with waxare conveyed with means for treating the cartons with blasts of vair and, if desired, with a sterilizing fluid so that the articles are cooled and the coating solidified, after which the articles are conveyed from the device.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described. illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view through one half of the apparatus.
Figure la is a similar view through the other half. l
Figure 2 is a top plan view of the air delivery tubes and the nozzles connected therewith.
Figure 3 is a section on the line 3-3 of Figure 1a.
Figure 4 is a section on the line 4-4 of Figure 1.
Figure 5 is a fragmentary top plan view showing the manner in which the cold air spray is directed into a carton at the.- same time cold air' is delivered against exterior parts of a carton.
Figure 6 is a fragmentary top plan view showing how a turntable conveys the cartons from the incoming conveyor to the outgoing conveyor.
Figure 'l is a perspective view of a filter device used in the apparatus.
In these views the letter A indicates'an elongated housing which is provided with the windows a. and the walls of which are insulated as shown at-b and a horizontal partition l divides the housing into an upper chamber B and a lower chamber C. v v
One end of the housing is provided with a pair of openings which are in communication with the upper chamber B andiaconveyor 2 extends through one of the openings and passes through the upper chamber to a point adjacent the opposite end thereof, this conveyor bringing in the articles to be treated in the apparatus and a secfio ond conveyor 3 parallels the conveyor 2 and is adapted to lead the articles from the chamber `B. Each conveyor is formed of a plurality of `the articles or cartons .pass from one end vof the chamber to a point adjacent the opposite end and then the turntable conveys the cartons from said one conveyor to the opposite conveyor which carries the articles to the first-mentioned end of the housing where they pass through the opening.
Within the chamber B, the cartons are treated to a blast of cold air preferably a mixture of cold air and a chemical sterilizing agent;V To that end there are mounted in the chamber B upper and lower series of elongated longitudinally extending, spacedparallel pipes .or conduits l.
As shown in Figure 2, each pipe 1 is of three diameters in order to insure the pressure of the air discharge from the nozzles associated with these pipes to be the same at each point of discharge,
As best shown in Figures 3 and 4 the intermediate pipes 1 have extending from opposite sides thereof and arranged in longitudinal series downwardly curved discharge nozzles 8, the nozzles 8 of the uppermost pipes l being so arranged as to discharge the air blast against the cartons entering and leaving the chamber B at one side of theA cartons adjacent the upper ends thereof, while the nozzles 8 of the lowermost intermediate pipes 'l are so arranged as to direct the air blast against one side of the cartons adjacent the lower ends thereof.
The uppermost outer pipes 'I are each provided with one series of nozzles 9 that so extend therefrom and are so shaped as to terminate above the c rtons 40 and substantially in alignment with the filling openings 40a in theupper ends of the cartons and as best shown in Figures 3 and 5. The purpose of having the nozzles 9 terminating in alignment with the filling openings 40a is to insure a blast of cold air being directed into the cartons for removing the heat therefrom and insuring a proper congealing of the interior coatings of paramn.
Also eachof the upper and outermost pipes l is provided with a second series of nozzles I0 arranged to direct blasts of air against the cartons adjacent the upper ends of the latter, and at the sides thereof opposite to the nozzles 8.
Also the lower and outermost pipes 1 are provided with a series of nozzles II projecting from one side thereof and arranged to direct blasts of air against the cartons at the sides thereof opposite tothe nozzles 8 associated with the lowermost intermediate pipes 1 and at a point slightly above the bottoms or lower ends of the cartons. AlsoI each of the lower and outermost pipes 1 has extending from the bottom side thereof curved nozzles I2.A These nozzles as clearly shown in Figures 3 and 4, have their discharge ends directed upwardly and are located beneath the upper runs of the conveyors 2 and 3 for directing upwardly blasts of air against the bottoms of the cartons.
It has been found in practice that by such an arrangement of nozzles as just described the force of the air blasts at the several points on the carton will be uniform so that such blasts of air will not interfere with the maintaining of the cartons in true perpendicular position as is desired and essential.
To provide for the air blasts just referred to there is suitably arranged in the chamber C and beneath the partition I a blower I5 disposed at one side of a vertical partition I6. The blower I5 is driven from an electric motor I1 through the medium of a suitable belt and pulley drive connection I8.
Blower casing I5 has its discharge end I9 merging into a conduit formation of a known shape and size and which provides for a sinuous passage 20 for the air being discharged from the blower.
The outlet nozzle I9 of the blower has sleeved thereon a casing 2I that is provided at one end thereof with a single outlet opening 22 from which extends a ared discharge funnel-like nozzle 23.
The nozzle 23 terminates at one side of a refrigerant coil box 24 containing the refrigerant coil 24' so that the air discharging from the nozzle 23 passes through the coil box 24 so that the temperature of the air is materially reduced. As the cold air passes beyond the coil box 24 it strikes an inclined baiile 26, and baiile 26 together with vertical baffles 21 serve to direct the cold air towards the inlet ends 28 of both series of upper and lower pipes 1. It will thus be seen that with the blower I5 in operation the air within the chamber C is drawn into the blower and forced by the blower through the coll box 24 to set up a forced circulation of cold air beneath the partition I, this cold air passing from beneath the partition I into the inlets of the pipes 1 from which, through the medium of the aforementioned nozzles the airis directed in forms of jets against the cartons to complete the congealing of the interior.and exterior of the cartons.
In connection with the above and as best shown in Figure 2 it will be seen that nozzles 30 are provided on the ends of conduits 3| that are tapped into the inlets 28 of a lower intermediate pipe 1 and a lower outer pipe 1. These nozzles direct air on the cartons before they enter the houslng.
It might be mentioned here that the circuitous or sinuous passage arrangement for the air discharging from the blower I5 is of a type recommended as a muiller for internal combustion engines since it provides for a discharge of the air with little or no noise.
As shown in Figure 1 the partition I adjacent the extreme rear end of the housing is formed to accommodate a suitable lter 35 which forms the only means whereby the air in the chamber above the partition I may pass from above the partition to below the partition into chamber C, consequently pure flltered air will be drawn into the blower I5 to be subsequently used in the subjecting of the cartons to the jets of air hereinbefore fully described and referred to.
Means is also provided whereby, if desired, the air forced by the blower I5 to the conduits 1 may bear a chemical sterilizing agent; such means in the' present instance consisting of a tank 36 containing such sterilizing agency and provided with a discharge nozzle 31 arranged to discharge the contents of the tank 36 into the inlet I5 of the blower I5. Air pressure or the like may be employed for forcing the contents of the tank 36 therefrom.
The turntable T is arranged so that the upper runs of the conveyor elements of assembly 2 pass.
over the turntable while the upper runs of the conveyor elements of the assembly 3 pass beneath said turntable.
The turntable Tis mounted on a vertical shaft 4I and on the shaft 4I are upper and lower disks 42 that are of less diameter than the turntable T and cooperate with substantially U-shaped guard rails 44 to maintain the cartons one behind the other as they pass from the conveyor 2 onto the turntable T and from the turntable T onto the conveyor 3.
For driving the turntable T there is provided any suitable type of gearing assembly 46 that is in turn driven from reduction gearing housed within a gear case 41. The .drive from the reduction gearing in the case 41 to the gearing 46 is obtained in the present instance through the medium of a belt and pulley drive 48.
pipes 1.
