FIELD OF THE INVENTION
[0001] The present invention relates to a machine capable of washing, storing, and dispensing cups in a fully automated manner, enabling the practical, efficient, and safe use of reusable cups. Its application aims to eliminate the use of disposable cups, which have significant associated environmental impacts. To this end, the machine offers far superior practicality and hygiene compared to manual washing, making its application viable in commercial establishments.
[0002] The field of application of the invention includes locations where disposable cups are traditionally used, such as offices, factories, and others. Specifically, although it can also be used in residential environments, the machine is optimized for locations with a large number of people, as it can store both clean and dirty cups so that there is no need to wait for the washing process, in addition to performing washes quickly, safely, and economically.BACKGROUND OF THE INVENTION
[0003] The use of disposable utensils is one of the major current obstacles when considering sustainability. Mostly made of plastic, in addition to being derived from petroleum and causing large greenhouse gas emissions during their life cycle, they can take hundreds of years to decompose. Furthermore, since a large part of the waste is not disposed of in appropriate places, it ends up being carried by rivers to the oceans. Over years, exposed to the action of the sea and UV radiation, they degrade into microplastics, which are ingested by marine life and indirectly by humans, potentially resulting in various harmful health effects.
[0004] Given the scale of the plastic problem, several initiatives have been undertaken to reduce or eliminate its use. However, many areas lack viable solutions, offering only alternatives with even greater environmental impacts or prohibitive costs. Specifically, it has been found that there are no satisfactory options available on the market to replace the use of disposable plastic cups.
[0005] Alternatives such as cups made from biodegradable materials, while reducing some of the problems associated with plastic, generally have even greater environmental impacts due to factors such as greenhouse gas emissions during manufacturing and transportation. In contrast, reusable cups have environmental impacts dozens of times lower than disposable ones, but present several challenges for their implementation in companies.
[0006] The major challenge with reusable cups lies in making their washing, storage, and supply practical, economical, and safe, so that companies can use them without difficulty and with high scalability. In the current state of the art, although there is no formal definition, there are some categories of solutions, such as: 1. Manual washing: This is the classic washing method, performed with sponges, traditional brushes, or ergonomic brushes specifically designed for cups. A major disadvantage of this method is the lack of hygiene, due to the accumulation of microorganisms in the sponges and brushes, which contaminate subsequent washes. Microbiological tests have shown a 70% reduction in microorganisms with manual washing compared to 99.9% with automated washing at 50°C using dishwashing soap. Another disadvantage is the lack of practicality, requiring the user to wash their own cup or a dedicated employee to perform this task. 2. Industrial washing machines: These are appliances commonly used in restaurant and cafeteria kitchens, capable of washing various dishes or specifically cups. They are very similar to traditional dishwashers, requiring the placement and removal of cups from inside. They offer high-quality washing, but a medium degree of automation. Their main disadvantages are the high cost, the need for an operator to perform the washing and move the cups between the machine and the consumption area, the need for suitable locations for the machine and for storing the cups, and the lack of drying capacity. In offices and industries, these factors constitute major inconveniences. 3. "Instant" washing machines: These are small size machines specialized in washing a few cups at a time, with a medium degree of automation and applications geared towards corporate environments such as small offices. The washing process is carried out at high speed inside a chamber that holds around 1 to 5 cups, requiring the user to wait for the process and store the cup in an appropriate place. Within this category, two machines were found being marketed: the Israeli FreshCUP, with a 30-second wash using traditional supplies (water, soap, and rinse aid), and the French AUUM, which uses only a mixture of air and water vapor at 140°C for 5 seconds, with a total duration of 15 seconds including drying.
[0007] The main disadvantage of this category arises in environments with a larger number of people, as they are unable to process a high demand for cups quickly. In an office with 50 people, for example, if they are having lunch simultaneously, the waiting time can generate queues and become a major inconvenience. Furthermore, even 15 or 30 seconds for a single user can become a considerable inconvenience in terms of practicality, since it will occur approximately 3 times a day. Another drawback is the need for the user to store the cups and the required adequate space for this. Finally, for machines with steam washing, there are minimum exposure times to meet the recommendations of health organizations, which suggest durations of around 5 minutes for the sterilization of viruses and bacteria. This makes it difficult to perform quick washes (of a few seconds) that are effective in cleaning and preventing the spread of disease. Moreover, the use of steam requires a considerable complexity of components, making the product difficult to manufacture.
[0008] 4. Fully Automated Machines: These machines not only automatically wash cups but also manage their storage and supply. Featuring inlet and outlet reservoirs, there is no need to wait for the washing and drying process. Therefore, their use is analogous to traditional disposable cup dispensers, wherein the customer takes a clean cup and returns it dirty after use, maintaining the same convenience and zero waiting time. Thanks to the reservoirs, it's also possible to handle peak demand, such as during lunch hours. Furthermore, washing times of just a few minutes allow for complete sanitization. Therefore, they offer several advantages over other categories in enabling the use of reusable cups in commercial environments such as offices and industries.
[0009] However, the major challenge for machines in this category is to perform the washing, storage, and dispensing process systematically, in small volumes, minimizing cost and maximizing the speed and quality of washing and storage capacity. Thus, the present invention aims to provide means to overcome such difficulties, which are evidenced by other documents in this and other categories, cited below.
[0010] Document KR101987953 describes an automatic glass washer that stores dirty and clean cups using rails arranged in spiral structures. Washing is done in a tank with the aid of a rotating conveyor with holes for the cups, and a second conveyor belt lifts the clean cups from the bottom to the top of the machine.
[0011] Document KR200178338Y1 describes a device that automatically washes and dispenses reusable cups, including a guide for receiving and storing used cups, a washing compartment, a rotating transport system with a plurality of receiving holes connected to the washing compartment, a sterilization and washing system that injects steam or cleaning water into the used cups at a prescribed pressure, and a discharge guide for the clean cups that directs them to a discharge hole.
[0012] Document KR101990522B1 describes a cup washing unit of an automatic cup washing apparatus, wherein a cup held by a plurality of cup holders installed on a chain is moved to a cup washing unit, installed in a lower portion of the chain. The unit rises to wash the inner and outer surfaces of the cup, allowing the cup to be washed automatically in a stable manner. To this end, the automatic cup washing apparatus comprises: a washing apparatus unit; a through-hole unit; a cup washing unit; an inner brush shaft; an outer brush shaft; a rotating body; a housing; a toothed ring; an inner gear; a washing unit housing; a gear; and a hose.
[0013] Document KR20060022528A describes an automatic glass washer that cleans and transports cups using a single motor connected to multiple mechanisms via gear systems. The document further describes the washer as small in size, featuring a reservoir for dirty cups and a separate reservoir for some clean cups, and is provided with a sterilization lamp.
[0014] Document KR102443547B1 describes an automatic washer of water that stores cups that stores dirty cups in a ramp system and stores clean cups in a series of ramp systems with the aid of a selector. Additionally, the document provides an external ramp to move the dirty cups to the washing tank, which uses ultrasound in the cleaning process.
[0015] Document KR100837222B1 discloses an automatic glass washer that eliminates residual germs and water in the cup in a separate area after washing them, using a hot air fan to remove the water and an ultraviolet lamp for sterilization. Additionally, the document describes a storage system at the exit, with forced upward movement of the cups.
[0016] Document WO2002028264A1 describes an installation for washing vessels such as cups and mugs, which washes and dries them as they are moved through a sequence of rotating discs at decreasing heights.
[0017] Finally, document EP0600125 (A1) describes an apparatus for cleaning drinking utensils, such as glasses, cups, mugs, etc., comprising an inlet station for receiving the utensils to be cleaned, an outlet station for receiving the cleaned utensils, means for spraying fluid onto the utensil, at least one brush unit for mechanical cleaning of the utensil, a means for transporting the utensils from the inlet to the outlet.
[0018] As noted, these and other glass washing machines do not meet the needs of commercial environments such as offices and industries, which require fully automated washing, storage, and dispensing processes, with reservoirs capable of serving a large number of people, high volumetric storage density, practical and time-free cup receiving and retrieval, as well as fast and efficient washing methods in the use of consumables, capable of handling different types of waste (such as coffee, juices, and soft drinks) and effective in disinfecting microorganisms (such as viruses, fungi, and bacteria).
[0019] Specifically, due to the difficulties imposed by restrictions on the movement of cups, the fully automated machines already known in the state of the art are not designed to wash and store cups compactly, requiring large spaces or having small inlet and / or outlet reservoirs. In addition to storage capacity affecting manufacturing costs and the space occupied in pantries and kitchens, it determines the number of people the machine can serve, making it a crucial factor for machines of this nature. Thus, it is evident that optimized internal configurations are of enormous importance.
[0020] Therefore, the state of the art lacks simple, environmentally sustainable, and economical solutions for constantly providing clean cups and constantly collecting used cups without requiring user action.
[0021] Thus, it is clear that the state of the art would benefit from an automatic glass washer with a reduced environmental impact that sanitizes and dries cups in a practical, fast, efficient and economical way, and with an optimized internal configuration to serve a large number of people.DESCRIPTION OF THE INVENTION
[0022] The objective of the present invention is to provide an automatic glass washing machine that stores, washes, dries, and moves cups in order to maximize the number of dirty and clean cups stored and minimize the volume occupied by the machine.
[0023] Another objective of the invention is to provide greater ease of manufacture and lower cost compared to other solutions, especially in washing and storage systems, which are commonly more complex.
[0024] Additionally, another goal of the automatic machine is to minimize the average time taken to wash each cup, maximizing the number of cups washed per day to serve a larger number of users.
[0025] Furthermore, another objective of the invention is to reduce the consumption of inlets (such as water, electricity, detergent, and rinse aid) during washing, thereby reducing the cost and environmental impact per cup washed.
[0026] These and other objectives of the invention are achieved by means of an automatic glass washing machine characterized by comprising: an inlet system configured to receive and transport one or more cups at a time to an inlet reservoir; the inlet reservoir is configured to store a plurality of dirty cups in a stacked manner, nested one inside another, in two or more columns; a washing system configured to wash one or more cups at a time on a washing platform; a conveyor configured to move one or more cups at a time; an outlet reservoir configured to store a plurality of clean cups and dispense them through one or more outlets; wherein the outlet reservoir comprises at least one type of storage among: one or more tubes, a ramp for horizontally oriented cups, a ramp for vertically oriented cups and a guide for horizontally oriented cups.

[0034] The present invention relates generally to an automatic glass washing machine 7 characterized by comprising: An inlet system 1 configured to receive cups through user insertion and transport one or more cups at a time to an inlet reservoir 2.
[0035] The inlet reservoir 2 configured to store a plurality of dirty cups.
[0036] A washing system 3 configured to wash one or more cups at a time on a washing platform 31.
[0037] A conveyor 4 configured to move one or more cups at a time.
[0038] An outlet reservoir 5 configured to store a plurality of clean cups and dispense them through one or more outlets 50.
[0039] Through the subsystems described, the automatic glass washing machine 7 is able to receive, store, wash and dispense reusable cups.
[0040] The following subsections detail different preferred embodiments of the subsystems that compose the invention. The following sections detail preferred ways of combining the subsystems, brought together in embodiments of the invention.
[0041] In the section on the first embodiment of the invention, a first preferred embodiment and a second preferred embodiment are described. In the section on the second embodiment, a third preferred embodiment and a fourth preferred embodiment are described.(II) RESERVOIRS
[0042] The inlet reservoir 2 and the outlet reservoir 5 are the subsystems of the automatic cup washing machine 7 responsible for storing dirty and clean cups, respectively. The presence of reservoirs is essential to ensure the proper functioning of the machine, as they allow multiple users to place and remove cups without having to wait for the washing process. However, positioning and movement restrictions imposed by the geometry of the cups make it difficult to construct compact reservoirs.
[0043] The present invention features optimized storage and movement ways to maximize the number of cups present in the smallest possible volume. The storage ways for the inlet reservoir 2 and the outlet reservoir 5 are chosen from: one or more tubes 20, a ramp for horizontally oriented cups 21, a ramp for vertically oriented cups 22, a guide for horizontally oriented cups 23.
[0044] Storage in one or more tubes 20 consists of storing cups stacked in columns, one inside the other. The main advantage of this storage method is the high volumetric density of cups obtained. A second advantage is the greater tolerance to residue, with the possibility of large gaps between the cups and the walls of the tubes 20, making it difficult for any blockage due to accumulated dirt to occur.
[0045] The tubes 20 comprise any type of channel capable of guiding stacked cups in columns, whether they are tubes, tubes with holes in the walls, rails, channels, among others. Preferably, tubes 20 are positioned vertically or slightly inclined, so as to take advantage of gravity to move the cups.
[0046] Preferably, storage with 20 tubes is done with a plurality thereof, in order to maximize the reservoir capacity without increasing its height. This aspect is especially relevant considering the limited range of heights that the machine can have, since the user must have easy access to the dirty cup inlet 10 and the clean cup outlet 50.
[0047] Preferably, the tubes 20 are positioned so that their inlets and / or outlets, when viewed from above, present a linear alignment, as illustrated in Figure 20, or a circular alignment, as illustrated in Figure 29 and more easily visualized in Figure 5. This allows the subsystems connected to the reservoirs to be constructed in a compact and optimized way compared to zigzag or rectangular alignments.
[0048] Preferably, tubes 20 in the inlet reservoir 2 store cups with their opening facing downward, so that they can be received into the washing system 3 already in the washing orientation. Preferably, tubes 20 in the outlet reservoir 5 store cups with their opening facing upward, so that they can be received from the washing system 3 with minimal movement and made available to the user at the outlets of the tubes 20 themselves.
[0049] For the outlet reservoir 5 with three or more tubes 20, it is preferable that the outlets 50 be equally easily accessible, preventing the formation of stacks of less frequently used cups and the consequent accumulation of cups therein. For example, for three tubes 20 with their inlets positioned circularly, if they are completely vertical, their outlets will also be positioned circularly, resulting in one of the cup outlets further back with less access and visibility. A preferable embodiment consists of inclining one or more of the tubes 20 so that their outlets are aligned linearly or nearly so, ensuring easy access to all.
[0050] Preferably, storage in one or more tubes 20 uses trapezoidal section cups with anti-stuck steps 71 at the bottom of the cup, which prevent the inner and outer walls of the cups from fully touching. This prevents the cups getting stuck when stacked by avoiding the creation of a vacuum, preventing friction from forced adjustment, and reducing friction from accumulated residue between the cups. It is extremely important that the stacked cups do not get stuck, even with the weight of the upper cups and the presence of sticky residues, such as coffee with sugar, chocolate drinks, among others.
[0051] Preferably, storage in one or more tubes 20 is done inside the machine to protect them from dirt and to occupy only the space of the machine. However, since storage in tubes 20 consists of storing cups stacked in columns, one inside the other, the stacks can also be positioned outside the machine. In the outlet reservoir 5, wherein the cups are already clean and only require easy user access, the stacks can accumulate on a table under or next to the machine. For example, clean cups can be stacked to a certain height, such as 10 cups, and then this stack is pushed out of the machine by an actuator. Several stacks of clean cups can then be created and pushed out of the machine, making it possible to store as many clean cups as will fit stacks on the table.
[0052] Unlike storage in tubes 20, wherein the cups are nested inside each other, ramp for horizontally oriented cups storage 21, ramp for vertically oriented cups storage 22, and guide for horizontally oriented cups storage 23 store the cups side by side, resulting in a lower volumetric storage density. However, due to their greater versatility in the shape they occupy, they can result in even higher total volumetric densities when considering the entire machine.
[0053] The ramp storage for horizontally oriented cups 21 consists of storing cups through a sequence of zigzag ramps with the cups positioned side by side horizontally, as illustrated in Figure 30. The cups move primarily by gravity, although additional mechanisms may be used to actively assist movement and prevent cups from getting stuck. The main advantages of this storage method are its ease of construction and low susceptibility to jamming by residue, making it suitable for both inlet reservoir 2 and outlet reservoir 5.
[0054] Preferably, ramp storage for horizontally oriented cups 21 and ramp storage for vertically oriented cups 22 use rails at the points of contact with the cups, instead of ramps and solid walls. This reduces the contact area with the cups and the area for residue accumulation, facilitating sliding. For example, metal circular section rails provide good sliding with plastic cups. It should be noted that, to facilitate understanding of the drawings, the ramps for horizontally oriented cups 21 in the figures have been illustrated without rails.
[0055] Preferably, ramp storage for horizontally oriented cups 21 and ramp storage for vertically oriented cups 22 use cylindrical cups, as they facilitate handling. Cylindrical cups roll in a straight line, while trapezoidal cups tend to roll in a curved path, requiring some slippage when rolling in a straight line. Despite this, trapezoidal cups are also viable, but may require greater inclinations to compensate for the extra friction.
[0056] The ramp storage for vertically oriented cups 22 consists of storing cups via a continuous ramp with alternating straight sections and curved sections, with the cups positioned vertically side-by-side, as illustrated in Figure 22. Its main advantage is that it allows for lateral expansion of storage space, with straight sections at different levels passing side-by-side. Thanks to its more oval shape, it achieves superior space utilization compared to circular spiral ramps. However, this storage method is more complex to construct and requires a steeper ramp incline to function solely by gravity, due to sliding friction instead of rolling friction.
[0057] Preferably, the ramp storage for vertically oriented cups 22 comprises mechanisms to actively assist in moving the cups, so that it does not depend entirely on gravity and steep inclines. For example, the mechanisms could be rotating wheels positioned on the curves of each level, in places where movement is more difficult. The wheels can be configured to provide adequate friction with the cup walls to push them if they become stuck and to slide without causing damage if there are more cups in front of it.
[0058] The ramp storage for vertically oriented cups 22 is particularly well-suited for the outlet reservoir 50, where the cups are clean and slide under the opening or bottom of the cup more easily.
[0059] The ramp storage for vertically oriented cups 22 is a less practical option in the inlet reservoir 2 due to the presence of residue on the dirty cups. The inlet 10, it is preferable to receive the cup horizontally, at an angle, or upside down so that any liquid inside the cup is discarded. Therefore, the ramp for vertically oriented cups 22 would need to receive them in one of these orientations and then switch to a vertical cup position, preferably with their opening facing upward so that residue does not stick to the rails and create friction. Although feasible, it presents a more complex construction than other storage methods for inlet reservoir 2.
[0060] The guide storage for horizontally oriented cups 23 consists of storing cups side-by-side between two plates with the openings of the cups in contact with one of the plates and the bottoms in contact with the other, as illustrated in Figure 33. The cups fall by gravity, pushing those below until they reach the reservoir outlet.
[0061] Preferably, guide storage for horizontally oriented cups 23 uses cylindrical cups. Cups with a trapezoidal cross-section come into contact with each other only by the edge with the largest radius, creating a torque that tilts the cup and increases friction with the walls, leading to jamming pretty easily.
[0062] Preferably, guide storage for horizontally oriented cups 23 uses mechanisms to undo jamming by shaking the cups, such as paddles inside that rotate when desired.
[0063] Preferably, guide storage for horizontally oriented cups 23 features walls with low friction in relation to the cups. For plastic cups, plates with a rough paint finish generate less friction with the openings and bottoms of the cups than smooth finishes.
[0064] Preferably, guide storage for horizontally oriented cups 23 is applied to the outlet reservoir 5, where it receives clean cups. Application to the inlet reservoir 2 is more difficult because the residue present in the dirty cups accumulates on the walls, increasing friction and leading to jamming, requiring more frequent cleaning maintenance.
[0065] For the inlet reservoir 2 with storage chosen between ramp for horizontally oriented cups 21, ramp for vertically oriented cups 22 and guide for horizontally oriented cups 23, an advantage over using a plurality of tubes 20 is the need for a simplified inlet system 1, which may consist of only the inlet hole 10. On the other hand, it requires more cup dispensing movements in the washing system 3 so that it can wash batches of more than one cup at a time.
[0066] For the outlet reservoir 5 with storage chosen between ramp for horizontally oriented cups 21, ramp for vertically oriented cups 22 and guide for horizontally oriented cups 23, a considerable advantage over using a plurality of tubes 20 is the possibility of a single outlet 50. Thus, there is no risk of users taking fewer cups from a specific outlet 50, causing the respective tube 20 to become full and preventing further washing. To minimize this effect, lights are preferably used to indicate which cup the user should take.
[0067] In a preferred embodiment, the inlet reservoir 2 and the outlet reservoir 5 have a storage capacity of at least 10 cups each, so as to supply groups of people taking or returning cups at the same time without having to wait.
[0068] Preferably, the inlet reservoir 2 and the outlet reservoir 5 are positioned on opposite walls of the cup washing machine 7 and are chosen from the following storage forms: plurality of tubes 20, ramp for horizontally oriented cups 21, ramp for vertically oriented cups 22, and guide for horizontally oriented cups 23. These storage forms can be arranged to occupy a flat rectangular wall, unlike spiral rails, for example. By positioning them on opposite walls, it is possible to obtain better use of the machine's volume, as well as allowing the washing system 3 and conveyor 4 to be placed between the reservoirs and significantly facilitating batch washing and handling. The positioning on opposite walls is exemplified in the preferred embodiments shown in Figures 19, 23, and 26. In the preferred form shown in Figure 2, even with tubes 20 arranged in a circular manner, it is also possible to take advantage of this positioning form to some extent by bringing each plurality of tubes 20 closer to the walls. With the suggested positioning on opposite walls, it is possible to optimize the internal configuration of the machine for significantly better space utilization. This proves extremely relevant in practice, given that storage capacity is a determining factor in the number of people the machine can serve, and that the space it occupies is often limited by practicality (such as fitting in pantries and kitchens, or even on top of tables) and cost (both in terms of construction materials and transportation).(III) INLET SYSTEM
[0069] The inlet system 1 is configured to receive the dirty cups through one or more inlets 10 and transport one or more cups at a time to an inlet reservoir 2.
[0070] Preferably, the inlet system 1 comprises an inlet drain 11 positioned in the area where the dirty cups are received, which is configured to drain any remaining liquid in the cup directly into the sewer.
[0071] Additionally, the inlet system may comprise one or more of the following: luminous or mechanical indicators to indicate the correct location or time for inserting the cup, actuatable mechanical locks to ensure insertion into the correct inlet 10 or insertion of only one cup at a time, and a display configured to present information to the user In one embodiment, the inlet system 1 provides direct transport of cups, with one or more inlets 10 connected directly to the inlet reservoir 2. The direct connection can be applied to inlet reservoirs 2 of all the types mentioned: one or more tubes 20, ramp for horizontally oriented cups 21, ramp for vertically oriented cups 22, and guide for horizontally oriented cups 23. For example, for inlet reservoir 2 with storage in tubes 20, the inlet system 1 can be the tube inlets 20 themselves exposed outside the machine. In the case of the ramp for horizontally oriented cups 21, the direct connection is illustrated in Figures 22 and 25.
[0072] In another embodiment, the inlet system 1 provides cup transport with the aid of mechanisms. Preferably, the mechanism distributes the cups into one or more tubes 20, chosen from either: an inlet platform 12 or a dispensing ramp 13.
[0073] The inlet platform 12 is composed of a rotating plate with slots for positioning the cups. The cups are received through the inlet 10, moved to the tubes 20 of inlet reservoir 2, and finally released.
[0074] The inlet platform 12 comprises a plurality of inlet dispensers 120, configured to selectively hold and release cups by means of one or more actuators 121.
[0075] Preferably, the inlet dispensers 120 comprise actuators 121 and inlet locks 122. These are mechanisms composed of sliding plates configured to selectively support the weight of the cups or release them to fall by gravity, as illustrated in Figures 5 and 6.
[0076] Preferably, the actuators 121 are actuators such as solenoids or motors positioned outside the inlet platform 12, actuating the inlet locks 122 by means of mechanical contact. Thus, rotating electrical connections are not necessary and it is possible to minimize the number of actuators 121.
[0077] The dispensing ramp 13 comprises a channel with one inlet and a plurality of outlets controlled by one or more actuators 121. It is configured to receive cups horizontally, convey them to the desired outlets, where they are released and rotated 90°, exiting vertically.
[0078] The dispensing ramp 13 has the central function of converting horizontally oriented cups from an inlet into vertically oriented cups for a plurality of outlets. Thus, it can be used to receive horizontally oriented cups from the inlet 10 and distribute them into tubes 20 of the inlet reservoir 2, as shown in Figure 20, but it can also be used to receive cups from the ramps for horizontally oriented cups 21 to distribute them vertically into a plurality of slots on the washing platform 31, as shown in Figure 24, in which case it acts as a washing dispenser 30.
[0079] Preferably, the dispensing ramp 13 features a channel with inclined rails, so that the cup slides easily and moves independently by gravity. Additionally, it is preferable that the rotation of the cups also be carried out by gravity, which can be achieved by supporting the bottom of the cup on a rail and leaving the opposite side free, causing the cup to rotate from horizontal to vertical as it falls. One embodiment comprises a fixed rail and a rail with retractable sections, making it possible to retract the section of the exit where the cup is to be released. To facilitate understanding of the drawings, an alternative embodiment to the use of rails has been illustrated in the figures.
[0080] Alternatively, the dispensing ramp 13 may feature active mechanisms to move and rotate the cup to its outlets, such as by means of conveyor belts, wheels with rotating slots, among others. These can help with dispensing reliability by preventing jams, but they generate greater complexity in construction.
[0081] Preferably, the dispensing ramp 13 has one or more auxiliary locks 131, configured to prevent new cups from advancing over the outlets when the cups are released. The auxiliary lock 131 can be, for example: plates that rotate horizontally or vertically (illustrated in Figure 20), a movable piston, a rotating slotted wheel (similar to that illustrated on the washing platform 31 in Figure 28), among other mechanisms capable of selectively controlling the movement of cups.
[0082] Preferably, the dispensing ramp 13 is configured to accumulate cups in its slots until it has cups above all the outlets, allowing it to release a plurality of cups at once. Alternatively, one or more auxiliary locks 131 are used to release one cup at a time, allowing it to selectively release the desired outlet for each cup.
[0083] In one embodiment, the dispensing ramp 13 has tiltable selector plates 132 at its outlets to select and guide the cups to the desired location. This embodiment is illustrated in Figures 20 and 23, where it is possible to see one of the tiltable selector plates 132 lowered and the cup falling.
[0084] In Figures 20 and 23, there are two auxiliary locks 131 and individual tilting selector plates 132 for each outlet. In this scenario, it is possible to select one cup at a time, or to fill the dispensing ramp 13 and release them all at once (in which case the tilting selector plates 132 would not need to be individual). In the case of releasing one cup at a time, the operating sequence exemplified is: the first auxiliary lock 131 opens, a cup enters, the first auxiliary lock 131 closes (to prevent any more cups from passing), the second auxiliary lock 131 opens, the cup is released, the first auxiliary lock 131 closes, and the cycle is restarted.(IV) WASHING SYSTEM
[0085] The washing system 3 is the subsystem of the automatic glass washing machine 7 responsible for washing dirty cups, comprising three internal subsystems: a washing dispenser 30, a washing platform 31, and a hydraulic circuit 32. Preferably, it also includes a drying system 33, so that the cups come out dry. These internal subsystems will be detailed in the following paragraphs.
[0086] The washing dispenser 30 consists of a mechanism configured to selectively release one or more stored dirty cups and transfer them to the washing platform 31. It can be constructed in different ways depending on how the cups are stored in the inlet reservoir 2 and how they are washed on the washing platform 31. Here, some preferred ways of implementing it will be described, applicable to one or more specific cases.
[0087] Preferably, the washing dispenser 30 is configured to hold and release one or more cups at a time from the inlet reservoir 2, causing them to fall by gravity into the washing system 3.
[0088] Furthermore, the washing dispenser 30 is preferably configured to dispense cups from the inlet reservoir 2 following these steps: attach the cup to the base of the stack, attach the cup directly above it, release the cup from the base of the stack, release the cup directly above it so that it takes its place. It should be noted that when the cup at the base falls and the cup directly above it descends to take its place, the rest of the stack descends as well, since they are responsible for supporting it.
[0089] For the inlet reservoir 2 with storage in one or more tubes 20, the washing dispenser 30 is preferably positioned at the base of the tubes 20 and configured to support the stacks of dirty cups and to selectively release them to the washing system 3. Preferably, the washing dispenser 30 is chosen from: washing lock 300, rotary washing lock 303, among other mechanisms that perform the same function.
[0090] The washing lock 300 is a mechanism comprising a lower plate 301 and an upper plate 302, capable of supporting respectively the last and penultimate cups of each stack. The plates can move independently or, preferably, together, so that only one actuator is needed to operate them. Additionally, tabs 302' can be used to assist in fine-tuning the positioning of the cups in relation to the plates.
[0091] As illustrated in Figures 7 to 10, the lower plate 301 and upper plate 302 assembly is initially positioned with the lower plate 301 supporting the last cup (the cup at the base of the stack), which supports the rest of the stack above it. When the assembly is moved horizontally, the upper plate 302 begins to hold the second-to-last cup, and then the lower plate 301 ceases to support the last cup, causing it to fall due to gravity. When the assembly is returned, the stack falls one position, with the second-to-last cup taking the place of the last one, thus restarting the dispensing cycle. It should be noted that the act of "holding" the second-to-last cup consists of preventing it from falling to the next position, which can be done in two ways: by making contact with the second-to-last cup and supporting it, or by maintaining a small gap and supporting it only when the last cup is released, as shown in Figure 10.
[0092] The rotary washing lock 303 is a mechanism comprising rotating elements 304 in contact with the edge of the last cup in the stack, configured to selectively release it as they rotate. This approach is somewhat more complex to construct, but its main benefits include: less susceptibility to mechanism jamming due to dirt accumulation and the ability to pull the last cup if it is stuck with the penultimate cup due to dirt accumulation between them.
[0093] Preferably, the rotary washing lock 303 also comprises sensors below its outlets to detect whether the cups have actually fallen. In addition to fault detection, the sensors can be used to assist in dispensing. For example, circular rotating rubber elements 304 can be configured to rotate until the fall of the last cups is detected by the sensors. This way, even for the simplest, purely circular geometry, it is possible to reduce the chance of faults due to some cups not falling or more than one cup falling from the same stack.
[0094] The rotating elements 304 can be manufactured in a variety of shapes and materials. The geometry can range from simple, such as circular and eccentric shapes, to complex irregular shapes. The material can be elastic, such as rubber, or rigid, such as metals and plastics. The design is similar to that of a cam follower, where the profile shape is determined so that rotational motion is transformed into a specific desired linear motion.
[0095] In a preferred embodiment, instead of being completely circular, the rotating elements 304 have one or more support teeth and / or contact teeth, illustratively represented in Figures 15 and 16 respectively as pointed reliefs (sawtooth style) and rounded reliefs (ridge style). The support teeth allow the cup to be supported by resting its rim from below, and not by friction with its side, which is important considering the weight of the stack of cups above it. The contact tooth helps to force the last cup out more effectively, following the inclination of its rim and pressing and pushing it down as the rotating element 304 rotates.
[0096] Furthermore, the support and contact teeth help creating a well-defined transition between supporting the last cup and supporting the subsequent cup, mechanically preventing failures such as the cup not dropping or more than one cup dropping at a time.
[0097] Furthermore, it should be noted that the profile of the rotating elements 304 can be designed to take advantage of the flexibility present in plastic cups, which can deform elastically by a few millimeters, allowing for work with less tight tolerances and more effective friction against the cup wall if desired, as illustrated in Figure 15 in the interference contact of the contact tooth. One or more rotating elements 304 can be used per stack, as well as one or more teeth on the elements, depending on the number of dispensing per rotation desired.
[0098] In a preferred embodiment, the rotating elements 304 use a material with some elasticity, such as rubber. This provides greater friction with the rim of the cup and cushions the fall of new cups, thus reducing noise.
[0099] For the inlet reservoir 2, which stores cups side-by-side horizontally, as in the ramp for horizontally oriented cups 21, it is necessary to rotate the cups by 90° if it is desired that the washing platform 31 performs the washing with the cups vertically with the mouth facing down. For this, the washing dispenser 30 must release, rotate and transport one or more cups per wash to the washing platform 31, which can be done by means of a dispensing ramp 13, among other mechanisms that perform the same function.
[0100] Alternatively, for the inlet reservoir 2 with storage made with cups side-by-side horizontally and washing platforms 31 that also wash cups horizontally, the washing dispenser 30 does not need to rotate the cup. Therefore, the washing dispenser 30 can be chosen from: a horizontal wheel with slots to move the cups, a dispensing ramp 13 without cup rotation, or other mechanisms that perform the same function.
[0101] The washing platform 31 is a compartment where dirty cups are washed. Depending on the internal configuration of the cup washing machine 7, the washing platform 31 can be mobile or fixed, with open or closed walls, capable of washing one or more cups. Furthermore, the washing platform 31 can be designed to wash cups oriented vertically with the mouth facing down or horizontally. Positioning them vertically with the mouth facing up is not practical due to water accumulation.
[0102] Ideally, the washing platform 31 is capable of performing batch washing of more than one cup at a time. This consists in the washing platform 31 having a plurality of cup slots and can start and finish washing the set of cups simultaneously, as illustrated in Figures 11, 18, and 22. This allows for a low average washing time per cup, while still maintaining the benefits of "long washes". Long washes, lasting several seconds or minutes, allow for better disinfection and dirt removal due to the longer exposure time. However, they limit the number of cups the machine can wash per day, a determining factor in its capacity to serve a large number of people. With batch washing, on the other hand, the average washing time per cup is the wash duration divided by the number of cups washed at a time, resulting in a much higher daily washing capacity.
[0103] Additionally, the proposed batch washing allows for lower consumption of inputs, since the plurality of cups shares certain fixed losses, such as residual mixture and heat losses in the hydraulic circuit 32.
[0104] Preferably, the washing platform 31 is mobile, capable of moving and / or rotating, allowing the movement of one or more cups before or after washing. By assigning one or more degrees of freedom to the washing platform 31, it is possible to simplify the design of other parts, requiring fewer degrees of freedom from the washing dispenser 30 and the conveyor 4, and requiring smaller free volumes for the movement of cups between the subsystems of the machine. As a result, the main benefit obtained compared to fixed washing platforms 31 is the ability to allow for more compact and simplified internal configurations for the glass washing machine 7, especially for batch washing systems 3.
[0105] Preferably, the washing platform 31 exhibits rotational movement parallel to the plane of the bottom of the machine, as illustrated in Figure 4, or linear, as illustrated in Figures 18 and 22. Other forms of movement are also feasible, such as tilting the cups or movements with more degrees of freedom, but are generally somewhat more difficult to construct.
[0106] In a preferred embodiment, the washing platform 31 comprises one or more internal spray nozzles 310 and one or more external spray nozzles 311, responsible for directing the mixture to the inside and outside of the cups, respectively.
[0107] Preferably, the washing platform 31 uses only cleaning methods that do not accumulate microorganisms and dirt, such as spray nozzles, total or partial immersion of the cup, water heating, use of detergents, among others. Thus, it does not employ brushes, sponges or other mechanical utensils that easily accumulate residue and promote the proliferation of microorganisms.
[0108] In a preferred embodiment, the washing platform 31 washes one or more cups with their opening facing downward. This allows for easier uniform washing and the reception of cups by the washing dispenser 30 and their removal by the conveyor 4, especially for storage in one or more tubes 20.
[0109] For washing cups with their opening facing downward, the washing platform 31 preferably comprises side guides 310' and circular guides 310". The side guides 310 center and accommodate the cups to be washed, preventing excessive movement during washing. The circular guides 310" retain some of the washing liquid to keep the openings of the cups submerged, as this is the area of the cup most contaminated with microorganisms and possibly stained with lipstick. The circular guides 310" have a small opening so that the washing liquid does not remain permanently trapped. Figures 11 and 12 show examples of side guides 310' and circular guides 310".
[0110] In a preferred embodiment, the cups are positioned with their opening facing downward on the washing platform 31, the external spray nozzle 311 is located above them, and the internal spray nozzles 310 are tubes located inside them. As a result, the gravity itself helps generating a uniform distribution of the mixture across the entire surface of the cup, resulting in high-quality washes even with the water flowing without significant pressure.
[0111] In a preferred embodiment, the cups are positioned with their opening facing downward on the washing platform 31, and the external spray nozzle 311 positioned above them is movable, being moved circularly (as illustrated in Figure 11) or linearly by an actuator. Thus, even though it is necessary to keep the path of the cups unobstructed when they enter, it is still possible to bring the spray nozzle closer to them during washing, covering the entire exterior of the cups without needing to spray water over long distances. In addition, a complementary function of the movable external spray nozzle 311 is to detect and release any cup jams that may have become stuck along the transport path.
[0112] In another embodiment, the washing platform 31 washes one or more cups oriented horizontally, with their opening facing sideways. This form facilitates the reception of cups stored horizontally in the inlet reservoir 2, as in ramps for horizontally oriented cups 21.
[0113] For washing cups positioned horizontally, it is possible to use internal spray nozzles 310 and external spray nozzles 311 and / or fully immerse the cup in water (unlike cups with their opening facing downward, where complete immersion is hindered by the air inside the cup causing it to float). Washing with spray nozzles is quite similar to washing cups with their opening facing downward. Immersion washing, however, has the main disadvantage of requiring a large volume of water to immerse the cup and the energy consumption for heating that volume.
[0114] For washing with fully immersed cups, the ultrasonic cleaning process can be applied to help remove dirt from the cup surface. In this case, the washing platform 31 features ultrasonic transducers 313, configured to agitate the liquid.
[0115] For washing with fully submerged cups, a preferable way to reduce water and energy consumption is to rinse the cup in a position subsequent to its immersion. For example, after immersion in the washing platform 31, the cup is moved above it and rinsed using spray nozzles. One benefit is using less water for rinsing, which requires clean water but not immersion. Another is saving time, since one cup can be immersed while the other is rinsed.
[0116] Furthermore, since the rinsing is performed at a downstream position, it is possible to partially replace, at each washing cycle, the water used for immersion on the washing platform 31, which requires heated water but not necessarily completely clean water. Therefore, some of the water from the previous immersion and the rinsing water can be reused, saving a significant amount of water and electricity.
[0117] More broadly, the water reuse method can be applied to any multi-stage washing process, with and without full immersion. Instead of filling and emptying the washing platform 31 for each washing stage (such as soaping, rinsing, and possibly applying rinse aid), it is possible to strategically reuse water between stages to reduce input consumption. For example, in the final stage of a washing cycle, the water is expected to be almost clean, and can be used in the first stage of the next washing cycle without causing a significant difference.
[0118] It should be noted that, although the water reuse method can generate a significant reduction in inputs, it is clearly not the same as using completely clean water. Therefore, it must be employed strategically, so that the impact is minimal or offset by other techniques. For example, when reusing water from a step, it may be necessary to slightly increase the temperature to achieve the same cleaning and disinfection performance.
[0119] The hydraulic circuit 32 consists of the set of peripheral components of the washing system 3 that assist the washing platform 31 in the washing process. There are a large number of viable ways in which the hydraulic circuit 32 can be implemented. The following paragraphs will detail some of the components and implementation methods.
[0120] The hydraulic circuit 32 comprises at least one component among: UV sterilization system 312, ultrasonic transducers 313, water inlet 320, wastewater outlet 321, tank 322, pump 323, solenoid valves 324, consumables reservoir 325, dispenser 326, water heater 327, boiler 328 and UV filter 329.
[0121] In one embodiment, the hydraulic circuit 32 operates according to the following steps. When a solenoid valve 324 is activated, water from the facility enters through the water inlet 320 and is conducted to a tank 322. When a level sensor detects that it is full, the valve is closed and the heating process begins, turning on a water heater 327 coupled to the tank 322. Then, the dispenser 326 adds detergent stored in a consumables reservoir 325 and the temperature is monitored until it reaches the desired value, such as 50°C, for example. With the mixture ready, one or more pumps 323 pump it through the internal spray nozzle 310 and the external spray nozzle 311, preferably alternately at specific intervals to avoid emptying the tank 322. To finish this soaping stage, a pump 323 empties the tank 322, discarding the dirty mixture through the wastewater outlet 321. Then, further soaping steps (with detergent), rinsing (water only), and drying (with drying liquid) can be performed, with the drying stage requiring a second dispenser 326 and a consumables reservoir 325. Depending on the design of the machine, the number of washing steps and their parameters (such as temperature, quantity of supplies) can be adjusted to optimize washing.
[0122] The water heater 327 consists of a device in contact with water capable of transferring heat to warm it. The water heater 327 can be a resistive element, which converts electrical energy directly into heat, a gas heater, a heat pump, among others. Additionally, the water heater 327 requires a temperature sensor to control the water temperature. Temperature control can be centralized, with the controller 60 monitoring the temperature sensor, or independently, with the temperature sensor being part of a thermostat, for example. It is also possible to use both methods together to obtain both versatility, with the temperature selection via the central controller 60, and robustness, using the thermostat as a safety measure for maximum temperatures.
[0123] The tank 322 consists of a container at least a few centimeters deep, configured to store and allow the circulation of water used during the washing process. The tank 322 receives water draining from the washing platform 31 and sends it back to the internal spray nozzles 310 and external spray nozzles 311 via pumps 323, allowing its circulation. Additionally, the tank 322 can also be connected via pumps 323 and / or solenoid valves 324 to the water inlet 320, wastewater outlet 321, dosing outlet 326, boiler 328, and other components, allowing it to act as a common point for hydraulic connections. Regarding positioning, the tank (322) can be built fixed to the machine housing, connected by hoses to the washing platform 31, or it can be built as part of the washing platform 31, moving along with it if the platform is mobile.
[0124] Depending on the internal configuration of the automatic cup washing machine 7, it may be advantageous to comprise a tank 322, which practically solves a set of requirements. The tank 322 acts as a location with a defined volume to contain the amount of water used in each washing step, ensuring the desired volume by means of a level sensor. The tank 322 allows water to accumulate at a sufficient depth to operate the spray nozzle pumps for a few seconds using large flow rates without lowering the level to the point of allowing air into the piping. The tank 322 can act as a common connection point between different components, minimizing the number of connections needed for the washing platform 31. For example, for a mobile washing platform 31, only its water outlet and its internal spray nozzles 310 need hoses connected if a fixed tank 322 is used. Finally, the tank 322 can be used practically as a water heating location, taking advantage of its depth so that the water heater 327 is fully immersed in the water.
[0125] Preferably, water heating is carried out by means of a boiler 328, which consists of a container specifically dedicated to heating, storing and supplying heated water. Thus, instead of performing the heating in the tank 322, which is involved in the water circulation through the spray nozzles, the boiler 328 is an independent component, capable of heating water in parallel with the washing process, and not as part of its steps.
[0126] Although heating in a separate component results in a more complex and less intuitive design, the benefit obtained by using the boiler 328 is extremely substantial. With it, instead of waiting for heating as part of the washing process, it is possible to simply release the already heated water, generating a significant reduction in washing time, a determining factor in the number of cups washed per day.
[0127] Given the limitations imposed by traditional electrical installations, the relevance of the boiler 328 becomes even greater. If heating is desired in a shorter period, it is possible to use a water heater 327 with higher power. However, this value is limited by the electrical network available on site. For example, a 127 V outlet with a maximum of 10 A provides a maximum power of 1270 W, and it is not practical to modify such infrastructure. Thus, instead of requiring high power only when hot water is needed, the boiler 328 allows continuous use of the maximum power available on site, acting as a "thermal battery". As an example, for a washing process with heated soaping and rinsing at room temperature, instead of heating the water only during soaping, it is possible to use the time of both steps, since the heating is done separately.
[0128] The boiler 328 comprises at least one of each of the following components: cold water inlet, hot water outlet, water heater 327, and temperature sensor. Additionally, the boiler 328 may comprise: level sensor, pressure and / or temperature relief valve, drain for sediment removal, sacrificial anode, and check valve at the cold water inlet.
[0129] Preferably, the boiler 328 has a hot water outlet at the top and a cold water inlet directed to the bottom. Therefore, the hottest portion of water is always dispensed first, since hot water tends to rise and cold water tends to sink. Furthermore, this method allows for dispensing water at the desired temperature even if the bottom of the boiler 328 is not yet at that temperature.
[0130] Additionally, an optimized configuration for the boiler 328 consists of having two sets of temperature sensor and water heater 327, positioned one at the top and the other at the bottom of the boiler 328. As a result, it is possible to release water identified as hot by the upper temperature sensor while the water heater 327 heats the cold water that entered from the bottom. If the cold water reaches the upper temperature sensor, then only the upper water heater 327 is activated, allowing only the water at the top to be heated first, so that it can be used more quickly.
[0131] Preferably, the boiler 328 and other components where heated water circulates (such as tank 322 and washing platform 31) have thermal insulation to reduce energy losses. Preferably, the boiler 328 is kept on during periods of frequent use and kept on standby during periods of low demand, such as at night, which reduces energy losses, affecting daily washing capacity a little or not at all.
[0132] In one embodiment, the automatic glass washing machine 7 features a UV sterilization system 312, which consists of applying UV lamps pointed at the cups. Exposing the cups to ultraviolet (UV) electromagnetic radiation sterilizes microorganisms on their surface, reducing the potential for disease transmission among users. Implementing this system presents four main challenges: preventing human exposure to UV radiation at all costs, avoiding cup degradation, exposing the entire surface of the cup to UV radiation, and minimizing the impact on washing time.
[0133] Preferably, the UV sterilization system 312 presents safety measures to prevent any exposure to UV radiation for humans near the machine, both during manufacturing, use, and maintenance. A first option is to position the UV lamps in the most enclosed location possible, preventing reflection outwards. For example, the washing platform 31, inlet reservoir 2, and outlet reservoir 3 can be constructed in this way. A second option is to use sensors to ensure that the UV lamps are only activated if there is no risk to the user. For example, limit switches can be installed in series with the UV lamps, positioned to interrupt the electrical current if a maintenance door is open. As a result, it is possible to use the UV lamps even in visible areas during maintenance, such as conveyor 4. To achieve even greater safety, both options can also be used together.
[0134] Additionally, since the UV sterilization system 312 is critical to the operation of the machine and the functioning of its UV lamps cannot be directly evaluated, it is important that it has self-diagnostic capabilities. Preferably, it should have sensors to identify faults in the UV lamps, such as a UV sensor positioned close to them.
[0135] Preferably, the UV sterilization system 312 is used in conjunction with cups made of materials that exhibit a low rate of degradation under UV radiation. Many plastics degrade with prolonged exposure to UV radiation, which is a common concern for outdoor applications exposed to sunlight. Therefore, plastics with low degradation rates or with additives are preferred. Glass and metal cups are also viable, but have the following disadvantages, respectively: ease of breakage and splintering, and inability to be used in microwave ovens.
[0136] Preferably, the UV sterilization system 312 is implemented in locations where the cups are already stationary, such as: washing platform 31, conveyor 4, inlet reservoir 2 and outlet reservoir 3. Thus, in addition to slightly or not increasing the washing time, it is possible to achieve longer exposure times, one of the determining factors for the degree of sterilization obtained.
[0137] Preferably, the hydraulic circuit 32 includes a UV filter 329, which consists of a container with a UV lamp and fluid passage therein. The UV filter 329 is connected to the hydraulic circuit 32 to expose the water circulating during the washing process to UV radiation, sterilizing circulating microorganisms, preventing cross-contamination between cups, and facilitating water reuse between washes. Since only the circulating water is exposed, and not the cups, there is no risk of degradation in plastic cups. Furthermore, the UV filter 329 also offers the significant benefit of greater practicality by preventing human exposure to UV radiation.
[0138] In one embodiment, the UV filter 329 is implemented as a standalone component applied to one of the water circulation hoses. The advantages are easy installation and no risk of human exposure to UV radiation, with the disadvantage that a relatively small portion of water is exposed at any given time.
[0139] In a second embodiment, the UV filter 329 is implemented by including a UV lamp in the tank 322. The advantages are the use of an existing container in the water circulation path and the exposure of a larger volume of water at any given time. As a disadvantage, it requires safety measures to prevent human exposure to UV radiation, such as those mentioned in the UV sterilization system 312. For example, the tank 322 must be sealed to prevent UV radiation from escaping, a sensor must be installed to turn off the UV lamp when the tank 322 is opened, or even a mechanical requirement must be made to disconnect the UV lamp before the tank 322 can be opened.
[0140] It should be noted that both the UV sterilization system 312 and the UV filter 329 have the potential to perform sterilization if the UV radiation is applied with adequate intensity and exposure time. However, they can also be clearly configured to perform disinfection if such a high degree of sterilization is not desired.
[0141] In an alternative embodiment, the washing system 3 uses water vapor instead of liquid water during washing. As a result, it is possible to use water vapor at temperatures above 100°C to carry out sterilization of the cups and more effectively remove dirt. The water vapor can also be mixed with air to reduce water usage. However, the use of water vapor makes some aspects of the hydraulic circuit 32 more difficult due to temperature and pressure, and also requires cups made of compatible materials.
[0142] In one embodiment, the automatic glass washing machine 7 uses cups with silver ions, which have their own disinfection capabilities. Silver ions can be presented as additives or coatings on cups made of materials such as plastic, glass, and stainless steel.
[0143] The drying system 32 consists of the set of components responsible for removing the remaining water on the surface of the cups after washing. Although not strictly essential, it is of great interest to reduce the amount of remaining water to offer a better user experience. The drying system 32 comprises at least one component among: fan 332, air compressor 333, and air heater 334.
[0144] The drying system 32 can use two physical mechanisms for water removal: evaporation and mechanical removal. For evaporation, it is necessary to drain the moisture removed from the cups, which can be done by air circulation with the external environment or by using an air dehumidifier. Additionally, an air heater 334 can be used in the blowers as a means of accelerating evaporation.
[0145] The fans 332 are mechanical devices used to create an airflow that which allows dragging and assists in the evaporation of remaining water droplets. Traditionally, they are divided into axial and centrifugal types. They can be applied in different ways, depending largely on the internal configuration of the machine. For the outlet reservoir 5 with ramp storage for horizontally oriented cups 21, it is possible to easily include fans 332 in the path. For the outlet reservoir 5 with tube storage 20, it is possible to channel the air through tubes 20, although the air path inside the cups becomes more complicated.
[0146] In a preferred embodiment, the drying system 32 uses components such as fans 332 to blow air onto the cups while they are on the conveyor 4, being moved from the washing system 3 to the outlet reservoir 5, as illustrated in Figure 2. Instead of performing the transport immediately, the conveyor 4 can take advantage of the washing time of the subsequent cups to dry the current ones. As an advantage, this method allows air to be blown in a well-ventilated environment, with easy access and the possibility of moving the cups at different angles to cover their entire surface. This form is especially useful for an outlet reservoir 5 with difficult access for drying.
[0147] In a preferred embodiment, the conveyor 4 includes an extra cup tilting step during cup movement, wherein the cups are tilted until the water accumulated on the outside of the cup bottom drains off, falling into an appropriate location, such as the washing platform 31 itself. Water accumulation occurs for washes performed with the cup oriented vertically with their opening facing downward.
[0148] In one embodiment, the internal spray nozzles 310 and the external spray nozzles 311 of the washing platform 31 also act as air blowers. As a result, it is possible to blow air after washing to remove, primarily by dragging, remaining water droplets from the cup. Because the spray nozzles have an optimized shape for the water to sweep across the internal and external surfaces of the cup, this same path allows the air to push the droplets to the edges of the cup, achieving highly efficient removal. In this embodiment, to allow air to travel through tubes, higher pressure air sources are preferably used, such as an air compressor 333 and a centrifugal-type fan 332.
[0149] It should be noted that, although it is quite practical to use the existing internal spray nozzle 310 and external spray nozzle 311 for blowing air, other components dedicated exclusively to blowing air can be used. The reasons may include, for example: having channel thickness optimized for airflow, having a larger contact area than a mobile external spray nozzle 311, or allowing drying in a location different from the washing platform 31 so as not to increase the washing time.(V) CONVEYOR
[0150] The conveyor 4 is the subsystem of the automatic glass washing machine 7 responsible for moving one or more cups at a time from the washing system 3 to the outlet reservoir 5 and / or from the inlet reservoir 2 to the washing system 3. For the proposed types of cup reservoirs, with top-down storage, the conveyor 4 has as its main movement the lifting of the cups. Additionally, it can also perform other translational and / or rotational movements.
[0151] In a preferred embodiment, the conveyor 4 transfers the one or more clean cups from the washing system 3 to the outlet reservoir 5. As a result, it is possible that the washing system 3 to be located at the bottom, optimizing the internal configuration of the machine.
[0152] In a preferred embodiment, the conveyor 4 is a robotic manipulator 40, which consists of an articulated mechanism configured to perform translational and / or rotational movements of one or more cups at a time. The mechanism can be synthesized using articulations (also called articulated joints or kinematic pairs) of different types, such as: rotational, cylindrical, prismatic, spherical, universal and helical.
[0153] Figures 13 and 18 illustrate examples of robotic manipulators 40 optimized for the internal configurations of their embodiments. They have an elevator 400, which moves vertically, and a manipulator gripper 401, which rotates the cups. Therefore, they present the minimum number of degrees of freedom to perform the rotation and translation required in the example. Robotic manipulators 40 with greater mobility, such as robotic arms, can also be employed. This greater versatility of movement can be applied both to move cups from the washing system 3 to the outlet reservoir 5 and to move cups from the inlet reservoir 2 to the washing system 3, also acting as a washing dispenser 30.
[0154] In a preferred embodiment, the manipulator gripper 401 consists of a base on which movable plates 402 slide, controlled by an actuator. The movable plates 402 preferably have fins with foam to effectively grip the cups, as illustrated in Figures 13 and 14. Alternatively, suction cups 404 actuated by compressed air can be used to grip the cups.
[0155] In an alternative embodiment, the conveyor 4 is a conveyor belt 41, which consists of a belt with slots for cups. The conveyor belt 41 can either carry the cup or batch of cups immediately after washing or fill each slot one by one. Preferably, the machine can be configured to perform the first option if the outlet reservoir 5 is empty and the second option if it contains one or more cups. Thus, the proposed method allows the conveyor belt 41 to be used as a means of storing clean cups.(VI) CONTROL SYSTEM
[0156] The control system 6 is the subsystem responsible for controlling the automatic cup washing machine 7, so that it can operate in an automated manner. The control system 6 comprises sensors, actuators, and a controller 60. Additionally, it may comprise a user interface.
[0157] The controller 60 consists of an electronic device capable of controlling sensors and actuators. The controller 60 comprises a device with processing capabilities (such as a microcontroller, microprocessor, system-on-a-chip (SoC), and single-board computer (SBC)) and an associated electronic circuit to interface with the sensors and actuators. The controller 60 can be a programmable logic controller (PLC), typically used in industrial applications, or developed for a specific application, a preferable alternative due to its lower associated cost and greater versatility.
[0158] Preferably, the controller 60 is configured to communicate remotely via the internet (or alternatively, other communication networks such as LoRa), enabling a range of advantages in machine operation. Specifically, integrating the machine into the Internet of Things (IoT) context greatly simplifies the management and maintenance of machines on a large scale. Preferably, the controller 60 is configured to allow remote access to one or more of the following functionalities: Monitoring of inputs, allowing for optimized, predictive rather than preventive replenishment. Notifications and transmission of diagnostics regarding operational failures, allowing maintenance services to be scheduled without the user even needing to make contact. Real-time monitoring of operational data, such as the number of cups washed, allowing for attribution of cost and environmental impact reductions provided by each machine and providing this information to customers. Over-the-air (OTA) firmware updates, in order to provide continuous product improvements without the need for physical travel.
[0159] The actuators required by the automatic glass washing machine 7 consist mainly of means to obtain rotational and translational movements in mechanisms such as the conveyor 4, the washing dispenser 30, among others. Thus, for each case there is a wide range of viable options, such as electric motors, stepper motors, servomotors, solenoids, pneumatic pistons, pneumatic motors, among others. Additionally, the rotation of motors can be easily converted to translation by means of racks and lead screws.
[0160] The sensors required by the automatic cup washing machine 7 consist mainly of means for identifying the mechanical positioning of moving parts, both of the mechanisms and of the cups. For this purpose, infrared sensors, limit switches, among others, can be used. Additionally, a temperature sensor is also necessary to control the water heating and, preferably, a level or flow sensor to control the water inlet.
[0161] In a preferred embodiment, the controller 60 is configured to store the current state of the machine in a non-volatile memory so that it can remember where it left off in case of a power outage. Therefore, when the power is turned back on, it can resume operation without the need for sensors capable of identifying the positioning of all parts. For example, if the machine can remember whether it was washing cups, it is not necessary to include sensors on the washing platform 31 to identify if there are cups when restarting.
[0162] In a preferred embodiment, the automatic cup washing machine 7 features a user interface consisting of a display for showing information. As a result, it is possible to display user instructions, error warnings, and full-machine notifications, as well as to assist in maintenance operations.
[0163] Preferably, the control system 6 includes a water monitoring system 61, which consists of one or more water property sensors applied to the hydraulic circuit 32 to monitor the circulating water during washing. The water monitoring system 61 may include sensors for turbidity, conductivity, pH, COD, among others. Its purpose is to detect the degree of water cleanliness in order to optimize washing parameters.
[0164] In empirical tests, it was observed that most cups arrive with residues that are relatively easy to remove by conventional washing, such as leftover coffee, juice, and soda. However, occasionally cups may arrive with a large amount of sticky residue, such as undissolved chocolate and instant coffee. In this case, the water may remain cloudy even after washing processes with more than 3 water changes, resulting in cups with residues that may be perceptible by smell, taste, or visually. As a result, the options arise to extend the washing process and waste resources in most cases, or eventually offer cups with traces of dirt.
[0165] Alternatively, the proposed method consists of optimizing the washing parameters based on the level of dirt detected by the water monitoring system 61. The parameters altered can be the number of steps and water reuse, as well as the amount of detergent and the water temperature. In a simple example, at the start of the washing process, the level of dirt in the water is measured to determine whether a simple wash or one with extra steps will be performed. During the last rinse step, the level of dirt is measured again. If it is still above the desired level, more steps are performed until the cups are clean.
[0166] Applying the suggested method for optimizing washes based on the water monitoring system 61 brings substantial benefits by reducing the consumption of supplies, minimizing the standard washing time, and allowing the maintenance of cleaning quality even for cups with a large amount of residue.FIRST EMBODIMENT OF THE INVENTION
