This invention relates in general to can handling equipment, and is more particularly concerned with the provision of an improved form of can discharge mechanism for use in processing apparatus of the vertical reel and spiral type, such, for example, as the cooler illustrated and described in my prior U. S. Letters Patent No. 1,651,912 dated Dec. 6,1927.
Coolers of the type referred are utilized in the canning industry for cooling the canned goods following the sterilizing operation, and, generally described, are made up of a closed upright cylindrical shell forming a cooling chamber therewithin, through which the cans are advanced along an upwardly trending helical trackway by means of a rotating can propelling reel, while being simultaneously subjected to the action of a cooling medium.
In the cooler disclosed in the patent referred to, the cooled cans are ejected from the apparatus by means of a rotating star wheel which operates to push the cans endwise from the traclrway and through a discharge opening in the shell,
from which they drop into a discharge chute and roll away to a suitable point of delivery.
While the discharge mechanism referred to has been found to be eminently satisfactory, and numerous coolers employing such mechanism have been and are continuing to give satisfactory performance in commercial practice,.it has been found that the speed of operation is somewhat limited in order to allow time for the cans to turn sideways in the discharge chute so that they may roll away.
. It is one of the principal objects of the present discharge mechanism which permits higher speeds of operation than have heretofore been obtainable.
Another object is to provide a can discharge mechanism adapted to discharge the cans in upright position, in which they are easier to handle and control.
A further object is to provide a can discharge mechanism which is adapted for use with a driven receiving conveyer whereby the cans may be positively conveyed to a suitable point of delivery instead of rolling by gravity.
A still further object is to provide a can discharge mechanism of simplified form, which eliminates the moving parts-(heretofore found necessary in such mechanisms. I
With these and other objects and advantages in view, as will hereinafter become more apparent, the invention will best be understood by reference invention to provide an improved form of can to the following description of an illustrative embodiment taken in connection with the accompanying drawings thereof, wherein,
Fig. l is a plan view, with certain portions broken away to facilitate illustration, of a cooler embodying a can discharge mechanism constructed in accordance with the present invention.
Fig. 2 is a sectional elevation of the cooler as viewed along the line 2-4! of Fig. 1.
Fig. 3 is a side elevation of the upper portion of the cooler as viewed along the line 3--3 of Fig. i.
Fig. l is a fragmentary perspective development of the terminal twisted portion of the can track as utilized in accordance with my invention,-illustrating its conformation and how the cans are discharged therefrom.
Figs. 5 to 9 are successive sectional views of the twisted portion of the can track as viewed along the line'5=5,,6-t, etc. respectively of Fig. l.
The cooler illustrated is of similar construetion to that disclosed in my prior patent hereinbefore referred to, except for the substitution of the can discharge mechanism of the present invention, so that only so much of the cooler will be described asjis deemed necessary for a full understanding of this invention, reference being made to said patent for other details of construction and operation with which the present invention is not directly concerned.
Referring first to Figs. 1 and 2, the cooler illustrated comprises an annular chamber formed by concentric cylindrical walls 5 and l, positioned about a vertical axis, and secured to a suitable base ,2. A cover plate 3 extends over the entire shell. The inner shell cylinder i" has secured to it, near its upper end, a spider ll, spaced below the cover 3. A fixed central vertical shaft 5 extends between said cover and said spider, and serves as a bearingfor an upper ring gear 6- of diameter somewhat less than shell I. p
The annular cooling chamber formed by the cylindrical shell walls i and i is provided with a helical can path or track formed by spaced helically trending if-rails l and l secured to the shells l and l, respectively. 'Ifhe cans, as indicated at as in Fig. 2, are rolled along said track by a reel formed of spaced vertical bars 9 secured at their upper ends to the rim of gear 6 by bolts I ll. secured by bolts ii to a ring gear l2, which lies in the lower portion of the annular cooling'chamill The lower ends of said bars are 7 bar and is guided by idler rollers l3 bearing against its inner periphery.
The can propelling reel thus comprises the upper ring gear'6, the lower ring gear 12, and the series of spaced vertical pusher bars 9. Its weight is supported entirely by the bearing of the upper ring gear 6 upon the shaft 5, a suitable thrust bearing l4 being provided at this point. In order to prevent distortion of the reel, itis driven ironi both ends, the upper and, lower ring gears 6 and l2 being engaged by driven pinions I1 secured upon a vertical shaft IS. The lower pinion H is driven by a gear l9, in turn driven by any suitable power source, not shown.
The cans are fed into the annular cooling chamber through an inlet aperture 20 formed in shell I adjacent the bottom of the helical track, and are discharged through an outlet aperture 2| formed through shell l adjacent the top ofthe track.
The cans may be introduced into the cooler by any suitable mechanism, for example, that illustrated in my prior patent referred to above. Such a mechanism is illustrated diagrammatically in Fig. 1, wherein upright cans are delivered along a runway 25 in properly spaced relation to a star wheel 28, which is driven in timed relation to the pusher bars 9, and serves to introduce the cans therebetween. The runway 25 has an inclined portion 32 which tips the cans over onto their sides as they enter the space between the pusher bars. Thus the cans are 'made to lie on their sides on the horizontal flanges of the T-rails, in which position they are rolled upwardly along the trackway by the pusher bars 9.
During their helical progression upward, the cans are subjected to a descending spray of cold water introduced at the top of the annular champart of the present invention except as the latter may be associated therewith, the present invention being concerned with the construction of the can discharge mechanism, now to be described.
As best seen in Figs. 3 and 4, the upper terminal portions of the rails I and I adjacent the can outlet aperture 2| are twisted outwardly toward the outer shell I to form a. longitudinally twisted section of trackway which serves to gradually up-end the cans as they are advanced thereover under the propulsion of the pusher bars 9.-
, the cans over the trackway, now cooperates with the stem or web 31 of the rail to support the cans on end.
As the cans are tilted out of engagement with the inner rail they are preferably given added support to counteract any tendency for them to topple back toward their original positions and this may be accomplished by increasing the width of the stem 31 of the outer rail as indicated at 38, to give additional lateral support to the cans. The flange 36 is likewise widened as shown to give added support to the can bottoms as they are tilted into upright position and prevent them from toppling away from the rail. The lower flange 39 of the outer rail is preferably cut away along the twisted portion of the rail to permit the outer edge of the rail to be twisted inwardly toward the path of the pusher bars without interfering with the cans rolling over the trackway therebeneath, and the upper flange 40 and stem or web 4| of the inner rail 1' may also be partially cut away ortapered to permit the rail to be twisted in close to the path of the pusher bars without interference with the bars.
As may be seen, the twist in the outer rail 1 is such as to bring the cans finally into full upright position to the outside of the path of the pusher bars, and the cans are thereupon discharged, under the urge of the oncoming cans therebehincl onto a revolving conveyer disc 42, driven in the direction indicated by the arrow in Fig. 1 and extending into the outlet aperture 2| into can receiving relation with the outer rail. The disc 42 is 'mounted upon and driven by a vertical shaft43 journalled in a bearing bracket 44 secured to the outside of the shell I. The shaft 43 may be driven by means of intermeshing gears 45, 46 and 47, the gear 45 being secured to said shaft 43, and the gear 41 being secured to a shaft 48 journalled in bearing brackets 49 and 50 mounted on the shell I. The intermediate idler gear 46 iscarried by a stub shaft journalled in the bracket 49. A pinion 52 secured to the upper end of the shaft 48 projects through a suitable opening in the shell I into engagement with the upper ring gear 6 by which it is driven.
cooperatively associated with the disc 42 are inner and outer can guides 53 and 54, respectively, which serve to direct the cans from the disc to any suitable receiving device (not shown). The outer guide 54 may be conveniently formed, as shown, by an extension of the stem 31 of the rail 1, and the inner guide 53 may be supported by brackets 55 attached. to the guide 54.
