The present invention relates in general to the field of ice vending machines. More particularly, the present invention relates to an ice vending machine that has a compact footprint. Additionally, the present invention relates to an ice vending machine that can quickly create bags of ice, allowing for less ice to be stored prior to bagging.
A variety of bulky ice vending machines are known in the art. Historically, ice vending machines consisted of large coolers where bags of ice that were manufactured at a different location are transported and delivered into the cooler. In addition to transportation costs, such a system oftentimes led to breaking of bags during delivery, melting of ice during the delivery process, and other undesired results.
More recently, ice vending machines had various components that allow ice to be manufactured and bagged within the machine, before being deposited into a storage section. These types of ice vending machines required a very large footprint to accommodate the bags of ice, as well as the components required to manufacture the ice, bag the ice, seal the ice in a bag, and deliver the sealed bag to a large storage compartment. Additionally, these machines typically had a large reservoir of ice held in a hopper after manufacture by an ice maker, but prior to bagging. In order to maintain that ice, additional components were oftentimes incorporated into the hopper to break up the ice, prevent it from thawing and refreezing, etc. Also, large storage compartments for bagged ice were filled with substantial quantities of ice that had to be manufactured and stored for extended periods of time to accommodate demand. For instance, these units were routinely larger than six feet in length and four feet in depth. These large storage compartments were necessary to meet demand because systems could only bag ice at relatively slow rates, such as four minutes per bag of ice or longer.
Apart from the large space required for installation and operation of these machines, which was problematic for many convenience and other stores that had limited amounts of space for such devices, the storage of large quantities of ice frequently resulted in stale bags of ice. Additionally, machines with large storage sections filled with bags of ice are often susceptible to theft.
A number of these deficiencies were addressed in U.S. patent application Ser. No. 16/432,531 titled “Ice Vending Machine and Related Methods”, which was filed on Jun. 5, 2019, which claimed priority to U.S. Application No. 62/681,328 titled “Ice Vending Machines and Related Methods”, which was filed on Jun. 6, 2018, the disclosure of both of which are hereby incorporated by reference. While these applications disclosed ice vending machines that were superior to the prior art described above, further improvements are desired.
For instance, there is a need for an ice vending machine having a significantly reduced footprint. Similarly, there is need for an ice vending machine that is capable of rapidly manufacturing ice and bagging the ice to meet demand. Flexibility in throughput is also desirable. Still further, ease in servicing an ice vending machine and ease in changing rolls of bags are sought after features. Overall, there is a need for an ice vending machine that is an improvement over the prior art.
In accordance with an aspect of the present invention, an ice vending machine is provided that includes a frame, a cabinet extending around the frame, at least one ice maker coupled to the frame, a first ice hopper, an auger, a second hopper, a bagging assembly, and a retrieval section. The first ice hopper is located beneath the ice maker and is configured to receive ice from the ice maker. The first ice hopper may be a drying hopping having a sloped bottom surface to drain water away from the second hopper. Thereafter, the auger moves ice from the first hopper through an opening into the second hopper. The bagging assembly receives ice from the second hopper, after which a bag of ice is deposited in the retrieval section. The retrieval section may include a refrigerated storage section that is located beneath the bagging assembly.
According to another aspect of the present invention, the cabinet is not more than 34 inches in depth.
According to yet another aspect of the present invention, the auger is rotated by an auger motor having a rotational speed of approximately 1500 rotations per minute, and a gear head that reduces the rotational speed to approximately 115 rotations per minute. Further still, the first hopper is configured to receive and hold between 300-400 pounds of ice.
According to another aspect of the invention, a sealing system is provided that includes a heating element, a pusher plate, and a biasing assembly coupled to the pusher plate. An opening is formed in the pusher plate, where the heating element may be exposed through the opening when the biasing assembly moves the pusher plate in order to seal a bag of ice. Furthermore, a pusher section includes a chute that extends from and is pivotable about the second hopper, as well as a motor that is coupled to the chute. The motor is configured to drive the chute towards the sealing system to facilitate the sealing of the bag of ice using the heating element.
According to another aspect of the invention, the machine includes a bag of rolls that are removably mounted to the frame, as well as a motor that is configured to advance a portion of the bag of rolls to the bagging system. Further, the machine includes a sensor that scans each bag from the bag of rolls. In the event that the sensor identifies an unverified bag design, the advancement of the bag of rolls to the bagging system by the motor can be terminated.
According to yet another aspect of the invention, a cradle is provided, where a bag from the bagging assembly is received. The bag may be opened by a blower, after which ice is deposited from the second hopper into the bag contained within the cradle, after which the cradle is rotated to deposit a plurality of bags of ice into the refrigerated storage section.
According to yet another aspect of the present invention, a method of using an ice vending machine is provided. The method includes dropping a plurality of ice from an ice maker into a first hopper, opening a bag using a bag assembly, rotating an auger contained within the first hopper to move ice towards an opening in the first hopper, dropping ice through the opening into a second hopper, dropping the ice through the second hopper into the bag, deactivating the auger, sealing the bag, and moving the bag to a retrieval section. The rotating step may include activating a motor having a rotational speed of approximately 1500 rotations per minute to rotate the auger. The auger may be rotated within the first hopper to move ice upwardly towards the opening in the first hopper between first and second sidewalls, after which the ice is dropped through the opening into a second hopper having a funnel. The ice is then guided towards the bag using a chute.
According to another aspect of the invention, the method also includes heating of a heating element, moving a pusher plate to expose the heating element, contacting the bag with the heating element to seal the bag, and moving the pusher plate to separate the heating element from the bag. Also, the method may include the steps of activating a motor associated with the chute extending from the second hopper, pivoting the chute and a support bag towards the heating element, pivoting the chute and supported bag away from the heating element, and disengaging the bag from a roll of bags.
According to another aspect of the invention, the method includes the steps of advancing the bag from a roll or bags using a roller, scanning a portion of the bag using a sensor, comparing the portion of the bag to a database of acceptable bag images, and deactivating rotation of the roller if the portion of the bag does not match the database of acceptable bag images.
According to yet another aspect of the invention, the method includes opening a bag in a cradle mounted within the retrieval section, filling the bag with ice from the first hopper through the second hopper, sealing the bag of ice, rotating the cradle about the retrieval section, and dropping the bag of ice into a refrigerated storage space.
These and other aspects, advantages, and features of the invention will become apparent to those skilled in the art from the detailed description and the accompanying drawings. It should be understood, however, that the detailed description and accompanying drawings, while indicating preferred embodiments of the present invention, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof. It is hereby disclosed that the invention include all such modifications.
Exemplary embodiments of the invention are illustrated in the accompanying drawings in which like reference numerals represent like parts throughout, and in which:
Illustrative embodiments of an ice vending machine in accordance with the present invention are shown in the figures. While many of the components associated with the ice vending machine and shown in the figures will be described herein, additional components, including those present in the prior art, could similarly be incorporated into the ice vending machine of the present invention.
Turning initially to
Additionally, the ice vending machine 50 has at least one ice maker 64 mounted to the frame 54. As shown, the ice maker 64 is mounted towards the top of the frame 54, although it could be mounted elsewhere. A variety of different ice makers 64 may be installed depending on the quantity of ice 51 that is needed on a routine basis. By way of example and not limitation, potential ice makers include a KM-1301 SAJ Hoshizaki ice maker, which makes up to 1,300 pounds of ice per 24 hours, Hoshizaki model KM-1601 SAJ, which makes up to 1,600 pounds of ice per 24 hours; Hoshizaki model KM-1900 SAJ, which makes up to 1,900 pounds of ice per 24 hours; Hoshizaki model KM-2200 SRJ3, which makes up to 2,200 pound of ice per 24 hours; or Hoshizaki model KM-2600 SRJ3, which makes up to 2,600 pounds of ice per 24 hours. In terms of selection of the appropriate ice maker, for ice vending machines 50 located at high-demand locations, a higher quality, and thus faster operating ice maker 64 is preferable. This ensures that the ice maker 64 is capable of manufacturing ice 51 quickly enough to fill the bags 62. Additionally, or alternatively, multiple ice makers 64 may be mounted to the frame 54 for high-demand locations. For instance, two KM-2600 ice makers on one system can produce up to 5200 pounds of ice per day, enough to bag 520 ten-pound bags a day despite the relatively small footprint of the ice vending machines described herein.
For locations having less demand, slower throughput ice makers 64 may be used. Additionally, the ice makers 64 need not be permanently mounted to the frame 54 to permit flexibility in replacing the ice maker(s) 64 in the field to meet the demand of a given location. This customizability allows the characteristics of the ice vending machine 50 to be changed based on analytics or other criteria used to determine the demand at a given location.
Still looking to
Once the ice 51 is made by the ice maker 64, it is dropped into a first hopper 66 of the ice storage and bagging section 65 that is located beneath the ice maker 64. As shown in
The first hopper 66 has a capacity of between 35-95 pounds of ice, more preferably between 50-80 pounds of ice, and most preferable approximately 65 pounds of ice. In contrast to ice vending machines of the prior art, the first hopper 66 has a reduced footprint, and is oriented in a particular manner relative to the cabinet 52 so that the cabinet 52 only needs to be 34 inches in depth. This allows the ice vending machine 50 to fit in a standard grocery store aisle, while still having sufficient capacity to manufacture and bag ice at a high speed.
Preferably sensors (not shown) are located within the first hopper 66. In one preferred embodiment, a first sensor is located near the top of the first hopper. When the first sensor is covered by ice, the ice maker is deactivated to avoid excessive manufacture of ice. Once the first sensor is uncovered, the ice maker is reactivated to ensure that sufficient amount of ice is present in the first hopper 66 for ice to be bagged and dispensed and/or stored.
The first hopper 66 includes an auger 80 that moves ice 51 from the lower section 74 to the opening 78 and into a second hopper 94 as best seen in
As shown in
While many of the components associated with the bagging system 98 are showed in U.S. application Ser. No. 16/432,531, which is incorporated herein by reference, some components are different and/or improved as will further be described below. The bagging system 98 includes a bagging motor 100 that rotates first and second bag rollers 101a, 102b to move a bag 62 into position prior to the filling of the bag 62 with ice, as well as a sensor 103. The bagging motor 100 is configured to move a bag or bags 62 quickly off of a roll 102 of bags to ensure high-speed filling of the bags 62 of ice. The sensor 103 is preferably configured to read a printed message, logo, bar code, etc. that is printed on the bag 62 while the bag 62 is moved into position about a viewing area 105 of the sensor 103. An encoder is preferably connected to the sensor 103 that ensures that the bags 64 are from an authorized provider. In a preferred embodiment, the roll of bags 102 is rotated a specified amount depending on whether the sensor is blocked or unblocked. For instance, the bag feed motor 100 may be a stepper type motor, where the roll 102 of bags is rotated a certain number of “clicks” depending on when the sensor is blocked or unblocked to position a new bag for filling In the event that the sensor 103 and encoder are unable to verify that the bags 64 are from an authorized provider because the message, logo, bar code, etc. are not correct, the machine 50 can be powered down and an error message can be displayed until a user is able to realign the roll of bags 102 such that the sensor 103 confirms they are from an authorized provider.
As best shown in
Once the bag has been filled by the bagging system 98, the bag 62 is sealed using a sealing system 120. The sealing system 120 may be similar to that shown and described in U.S. application Ser. No. 16/432,531, although some components are different and/or improved as described below. In the illustrated embodiment, the sealing system 120 includes a heating section 122 and a chute pusher section 124, as can best be seen in
In addition to the heating section 122, the chute pusher section 124 is also configured to help bias the bag 62 appropriately to ensure proper sealing of the bag. More specifically, the chute pusher section 124 includes components that enable movement of the chute 89 relative to the heating section. More specifically, the chute pusher section 124 includes a vertical portion 136 that is located directly adjacent to the chute 89. When the bag 62 is being sealed, a motor 138 connected to the vertical portion 136 by an arm 139 is activated to enable movement of the vertical portion 136. The vertical portion 136 presses against the chute 89 to move the chute 89, and the bag 62 resting upon the chute 89, towards the heating section 122. This further ensures the appropriate amount of contact between the bag 62 and the heating element 126 when the bag 62 is being sealed. The chute pusher section 124 may also include a horizontal element 140. The horizontal element 140 may include a perforated edge 142 that further assists in the separation of the bag 62 once the bag 62 is sealed. Additionally, to further assist with the separation of the bag 62 once the bag 62 is sealed, the bag rollers 101 may be rotated in the reverse direction once the bag 62 is sealed to break the seal between the formed bag 62 and the remaining roll of bags 102. Once the bag 62 has been sealed, the motor 138 is reactivated in the opposite direction to return the chute pusher section 124 to its original position as shown in
Next, the retrieval storage section 144 will be further described. More specifically, beneath the second hopper 94, the ice vending machine 50 has a storage section 144 for stacking and storing bags. More specifically, the frame 67 may be mounted to the storage section 144. Since the bags 62 may be stored for extended periods of time, the storage section 144 is insulated and cooled to an appropriate temperature to maintain the ice in solid form. As such, bags 62 of ice may be manufactured until the storage section 144 is partially or substantially filled depending on the settings of the machine 50. Preferably, the interior of the storage section 144 has a fill sensor 146. The ice vending machine 50 continues creating bags 62 of ice until the fill sensor 146 is triggered. In one preferred embodiment of the present invention, the fill sensor 146 is in the upper 25% of the storage section 144. Once the fill sensor 146 has been blocked, the manufacture of ice and filling of bags 62 can be stopped. Once enough bags 62 of ice have been removed from the storage section 144, the fill sensor 146 will no longer be triggered, in which case the production of bags 62 of ice will resume until the fill sensor 146 is again triggered, at which point manufacture is again suspended.
Additionally, the ice vending machine 50 has a cradle 148 which supports the bags 62 as they are filled with ice, and then deposits the filled bag into the storage section 144. Preferably, as shown in
Preferably a bag full sensor 158 is present that monitors the fill level of a bag 62 that is contained within the cradle 148. In one preferred embodiment, the sensor 158 senses when the bag 62 is partially, but not completely full once the sensor 158 is blocked. When the sensor is blocked, the auger 80 continues to rotate by a control panel a specific number of times to ensure the bag 62 is filled to the appropriate level. By way of example, when a 10-pound bag of ice is desired, the bag 62 can be filled until the sensor 158 detects that 8 pounds of ice are in the bag 62. Thereafter, the auger 80 is rotated a predetermined number of additional rotations to deposit two additional pounds of ice to result in the desired 10-pound bag of ice. Such a configuration results in more accurate bag weight regardless of how much ice is contained in the first hopper 66.
Regardless of when the bag 62 is determined to be full, it is sealed as described above and then prepared for deposit into the storage section 144. As shown, the cradle 148 is connected to a motor 159 with a drive chain 160. More specifically, the drive chain 160 rotates the cradle 148 in a first direction until the bag 62 slides out of the cradle 148 and into the storage section 144 as shown in
As shown in the figures and described above, the ice vending machine 50 has a compact size compared to traditional ice vending machines that required a large footprint. More specifically, the ice vending machine 50 has exterior dimensions of approximately 48 inches wide by 32 inches deep by 110 inches in height, with the interior dimensions being 44 inches wide by 28 inches deep. Having such a small footprint is beneficial in that the ice vending machine of the present invention can rest on a standard shelf or fit in the space of a standard shelf of a grocery or convenience store. Because the ice vending machine 50 is approximately 48 inches wide, it is as wide as a standard grocery store shelf The reduced footprint means that there is less space to store ice in a hopper 66. However, the combination of the speed with which the ice maker 64 makes ice and the power of the motors associated with the auger 80 and other components, the ice vending machine 50 is still capable of quickly filling, sealing, and delivering bags of ice as described above and minimal if any ice is stored in hopper 66.
The ice vending machine 50 has been optimized for quickly bagging the ice, while having a relatively small footprint. For instance, in a preferred embodiment, the ice vending machine is equipped to make a 10-pound bag of ice in approximately 15 seconds. In other embodiments, a 10-pound bag of ice is made in less than 15 seconds. In still other embodiments, a 10-pound bag of ice is made in less than 30 seconds.
In the illustrated embodiments, the machine 50 is operated using a user interface 162 mounted to the cabinet 52, such as a touch panel. In alternative embodiments, the machine is configured to communicate electronically with external communication devices such that bags 62 of ice can be ordered remotely, for instance by paying a cashier, ordering a bag on a phone or tablet application, ordering a bag online, or any other way known to those having ordinary skill in the art.
While the storage section 144 is shown to be insulated and refrigerated, other components of the machine could also be insulated and refrigerated if desired.
Additionally, in certain preferred embodiments, the ice vending machine is delivered in multiple sections and later assembled. For instance, the storage section 144, the ice storage/bagging section 65 and associated components including the hoppers 66, 94 and bagging system 98, and the ice makers 64 could be assembled on site. Additionally, as mentioned above, the ice makers 64 may be changed or the number of ice machines increased or decreased depending on the needs of a given location. Further still, various machines 50 and associated components may be in communication with one another. For instance, when one machine 50 is low on ice or out of ice, a notification may be transmitted so that individuals may physically move filled bags 62 of ice from a location having a surplus to the location that has an insufficient number of filled bags 62 of ice. The machines 50 and associated systems may be configured to allow for and track this borrowing of bags from one to another. Live, online data may be used to monitor such activities and ensure sufficient supply to all machines 50. Further still, live, online data may be used for other purposes, including to plan for preventative maintenance, track operation and breakdown of different components, identify machines that need to be replaced or exchanged with larger or smaller ice makers, and the like in order to optimize operation of machines 50 in general and at specific locations.
It should be understood that the above description, while indicating representative embodiments of the present invention, is given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof, and the invention includes all such modifications.
Various additions, modifications, and rearrangements are contemplated as being within the scope of the following claims, which particularly point out and distinctly claim the subject matter regarding as the invention, and it is intended that the following claims cover all such additions, modifications, and rearrangements.
The present application claims priority on U.S. Provisional Patent Application Ser. No. 63/217,002, filed on Jun. 30, 2021, and entitled Ice Vending Machine with Reduced Footprint, the entirety of which is hereby incorporated herein by reference.
