Abstract
An apparatus for storing ice in a container and dispensing ice from the container is provided in the form of a storage bin, having ice agitating apparatus for engaging ice to loosen the same and to keep ice particles from adhering together in a common mass. An ice dispenser is provided for delivering ice from a lower to an upper end. The ice dispenser and the ice agitator are provided with separate drives.
Description




BACKGROUND OF THE INVENTION




Ice dispenser bins are used in many situations, wherein ice is periodically made or generated and delivered or dropped into a storage bin, where it resides until the need arises to use the ice. In order to keep the ice pieces or particles from all adhering together into one large structure, it is known to agitate the ice. Generally, the ice pieces are dispensed from a lower location in the bin, to an upper location, to be discharged to bags, a cart, or other suitable container.




Because ice is delivered from an upper location to a lower location, to be later moved from a lower location to an upper location, it is known that there sometimes forms a bridge of ice pieces, inhibiting the delivery of ice from the upper location to the lower location.




It has become commonplace to periodically break up the bridge by reaching into the bin, manually, with a paddle, to strike the ice bridge and release the pieces or articles, to fall to the bottom of the bin.




In some cases, there is provided a drive for lifting ice from the bottom of the bin to the discharge, and when ice is thus being discharged, ice in the bin is simultaneously agitated to break up any bridge then forming, and to loosen ice particles so that they can fall to the bottom of the bin.




One disadvantage of such prior art type of devices is that they lack durability and require manual bridge-breaking intervention in order to keep the ice loose so the ice will properly dispense. Such manual agitation can create adverse sanitation problems.




Additionally, prior art ice dispensing equipment is often lacking in versatility.




Some users of ice dispensing equipment, such as supermarkets, purveyors of meat and fish and vegetables, desire the ability to fill large containers, rather than simply to fill bags of ice. For example, the ability to optionally fill carts as well as bags is a feature that has been missing from the art.




SUMMARY OF INVENTION




The present invention is directed to providing an ice storage bin having a dispenser for dispensing ice therefrom and an agitator for engaging ice pieces and agitating them, wherein there are provided driving means for driving the ice dispenser and for driving the ice agitator, such that they can be driven separately from each other.




Additionally, there is an upper bin section that has tapered walls to prevent bridging of ice therein, which facilitates the gravity dropping of ice from the upper bin to the lower bin. The lower bin section is separate from its structural support or frame, the latter carrying the drive loads, which frees the lower bin from carrying the drive loads.




Accordingly, it is an object of this invention to separately drive an ice dispenser and an agitator for ice in a storage bin.




It is a further object of this invention to accomplish the above object, wherein ice is delivered from a lower location within the bin to an upper location for discharge of ice.




It is yet another object of this invention to accomplish the object immediately above, wherein different types of containers, such as bags, carts, etc. can be used to receive ice discharged from an upper end of the bin.




It is a further object of this invention to accomplish the above objects, wherein the agitator comprises right and left, preferably somewhat helically configured and oppositely directed agitators carried on the same rotating agitator bar, whereby thrust loads in each direction from the right and left agitators tend to offset each other.




It is another object of this invention to provide an upper bin section that has tapered walls, to prevent bridging of ice therein.




It is yet another object of this invention to have a lower bin section that is separate from the lower structural frame, such that the structural frame carries the drive loads; not the lower bin section.




Other objects and advantages of the present invention will be readily understood upon reading the following brief descriptions of the drawing figures, detailed descriptions of the preferred embodiments, and the appended claims.

DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS




Referring now to the drawings in detail, reference is first made to

FIG. 1

, wherein there is shown the apparatus


10


of this invention, including an upper ice bin


11


and a lower ice bin apparatus


12


.




The ice making apparatus (not shown) may be of any conventional type, in that the particular ice making apparatus does not form an essential part of the present invention. Generally, the ice making apparatus will, however, be a suitable type of apparatus for making ice in the form of ice cubes, pieces, particles, shavings, or nuggets, and will generally be disposed above the upper bin


11


, although, in the alternative, the same could be disposed at a location remote from the ice bin


11


, with a suitable delivery system for delivering ice into the ice storage area provided by the bin


11


. However, preferably, the ice making apparatus will be disposed generally above the bin


11


, such that ice may pass to the ice bin


11


, via gravity, and then enter the bin


12


, via gravity.




With reference to

FIG. 2

, it will be seen that the bin


9


has front, left and right side and back walls


13


-


16


, as shown, and an open upper end


17


, for receipt of ice therein.




Ice agitators


18


and


20


are provided in the bin


9


.




Agitator


18


comprises a pair of left and right wire augers


21


and


22


, preferably generally helically constructed, as shown, each carried by the same agitator bar


23


, such that, when the shaft


25


is rotated in the clockwise direction shown at


24


, the bar


23


which is connected to the shaft


25


will likewise rotate in the clockwise direction, such that the augers


21


,


22


will tend to drive ice toward the opposite auger, such that ice pieces or particles will tend to move toward the center of the bin


9


, between the walls,


14


,


15


.




The bar


23


may likewise carry radial rods


26


,


27


, generally configured as shown, to also facilitate ice breakup.




The agitator


20


likewise comprises a pair of oppositely arranged, preferably helically configured wire augers


31


,


32


, carried by the bar


33


, that is likewise driven by shaft


34


, for rotation in a clockwise direction


35


, for conveying ice toward a central zone


36


generally near the back wall


16


, at the lower end of the bin


9


. The augers,


31


,


32


, like the augers,


21


,


22


, being arranged in pairs carried by their respective bars


33


,


23


, are disposed such that the thrust loads resulting from conveying ice are caused to oppose each other.




It will also be noted that the sloped bottom wall


37


near the front wall


13


and the curved bottom wall portions


38


,


40


near the back wall


16


are configured to cooperate with the augers of the respective agitators


18


,


20


, to cooperate in moving ice pieces or particles toward the central back or rear zone


36


.




The agitator shafts


25


,


34


are mounted in appropriate bearings


29




b


,


29




f


and


29




e


,


29




g


carried on opposite frame members


44


,


39


, on each side of the frame, outside respective side walls


15


,


14


of bin


9


. In this regard, it will be noted that in

FIG. 1

a sheet metal cover


43


is shown as being open, for the sake of clarity.




With reference now to

FIGS. 5 and 6

, it will be seen that the upper bin


11


has internal opposite side walls


11




a


and


11




b


, and opposite rear and front walls


11




c


and


11




d


, that are at an angle “a” with the vertical, as shown. The angle or taper “a”, is selected such, that ice located in the upper bin


11


will be prone to fall from the bin


11


, via gravity. It has been found that an angle “a” of approximately 2° is appropriate to facilitate such discharge.




With reference now to

FIGS. 7-11

it will be seen that the lower bin


9


, inside the bin apparatus


12


, has a sloped inner front wall


37


, and rear wall portions


38


,


40


, that are likewise sloped, to facilitate discharge, via gravity, of ice into the center zone


36


shown in

FIG. 10

, for dispensing therefrom, as will be described hereinafter.




It will be seen, with reference to

FIGS. 7-11

, that the bin


9


is separate from the frame of the bin apparatus


12


.




In this regard, reference is made to the detail view shown in

FIG. 9

wherein the bar


23


will be seen to terminate in shafts


25


at opposite ends (only one end being shown), and that each shaft


25


passes through a clearance opening


29


in wall


14


of bin


9


, with its bearings


29




b


and


29




f


mounting the same for rotation, and with the bearings


29




b


and


29




f


being physically mounted in and carried by the frame strut portions


44


and


39


. Suitable non-supporting seals


29




a


are provided, for sealing the shaft


25


across clearance opening


29


.




Thus, it will be seen that thrust loads in axial directions, and radial loads as well, are not carried by the walls


14


,


15


of the bin


9


, but rather, are carried by the supporting frame for the bin apparatus


12


.




Similarly, with respect to

FIG. 11

, it will be seen that the bearing


42


is carried by frame member


44


, not the wall


14


of bin


9


and that a suitable seal


29




c


likewise seals clearance opening


29




d


in wall


14


and that thrust loads from bar


33


are transmitted to the frame member


44


via bearing


42


and to thrust bearing


29




e


which likewise is carried by the frame, and not the bin


9


.




A pair of sprockets


45


,


46


are shown, in

FIGS. 1 and 3

, mounted on the respective shafts


25


,


34


, commonly driven via a common drive chain


47


that, in turn, is driven via drive sprocket


48


carried on the shaft


50


of the agitator drive motor


51


. Motor


51


may be of any suitable type, such as an alternating current A.C. electric motor, and may be provided with a take-up idler sprocket


52


.




An ice dispenser, generally designated by the numeral


60


is provided, in the form of an acutely angled dispenser tube


62


, generally mounted and disposed at an acute angle, preferably of 45° with the vertical, or with the front wall


13


, as shown in

FIGS. 1

thru


4


. The dispenser


60


includes a tube


62


having an ice inlet


63


at the lower end, in the upper portion thereof, to receive ice pieces or particles from the bin zone


36


at the lower back or rear end of the bin


9


, and to deliver the ice upwardly to an ice outlet


64


at the upper end. The dispenser


60


includes a dispensing auger mounted in the tube


62


, and preferably in the form of a continuous helically configured, rotatably driven auger


65


disposed within the tube


62


, to enable carrying ice from the dispenser inlet


63


, to the outlet


64


. The auger


65


is rotatably driven by a preferably electric A.C. motor


66


, via suitable chain drive


67


, for driving the auger


65


.




The motor


66


is driven completely separately from the motor


51


, such that the operation of the agitators


18


and


20


via the motor


51


is not tied to the operation of the auger


65


via its motor


66


.




The motor


51


may be controlled by a suitable timer, schematically shown at


70


, if desired.




The operation of the dispenser motor may be controlled by a suitable proximity detector


71


or the like, in the form of a switch, infrared beam, or any other suitable switching or detecting mechanism, for activating the motor


66


to cause the auger


65


to rotate and deliver ice pieces or particles up the tube


62


, to discharge at


64


, via a discharge chute


72


. The chute


72


may have an inside chute component


73


and an outside chute component


74


, with the inside chute component


73


being adjustable via positioning of a suitable adjusting handle


75


, for delivering ice into a bag (not shown) removably carried on bag-holding pins


76


beneath the chute


73


.




Additionally, the bag (not shown) for receiving ice may be carried on a suitable lower support


77


, mounted at


78


on generally vertically disposed support


80


, which support


80


is also pivotally mounted at


81


, to be moved toward a more rearward direction from that shown in

FIG. 3

, upon activation of a suitable handle


82


for varying the position of the supports


77


and


80


, so that carts (not shown) can be filled.




To fill carts, the support


77


is removed, and the support


80


is pivoted inward. The handle


75


is actuated to position the chutes


73


and


74


outwardly, relative to the front of the apparatus


12


.




If desired, a blower (not shown) may be housed within the cover


90


shown in

FIG. 7

, to facilitate blowing open a bag, when ice is to be dispensed into a bag, as distinguished from a cart. This facilitates semi-automatic bag filling. The air is used in conjunction with the inner and outer chutes


73


,


74


to open the bag and when ice is delivered the outer chute


74


traps the bag in an open position.




It would thus be seen that the goals of the present invention as set forth in the objects and summary of the invention, as well as in the appended claims, are complied with. It would be understood that various changes may be made in the details of construction, as well as in the use and operation of the apparatus of the present invention, all within the spirit and scope of the invention as recited in the appended claims.
