Description

[0001] MODULAR AND AUTOMATED DISPENSER FOR DISCRETE OBJECTS

[0002] This document claims priority from Australian provisional patent application no 2023903132 in the name of Mr Wally Robert Cloud the contents of which are hereby incorporated in their entirety.

[0003] Technical field

[0004] The present invention relates to a system for dispensing objects. The system comprises a container for dispensing objects, such as tablets, medications, vitamins and the like, from an internal reservoir.

[0005] Background

[0006] The consistent and regular intake of medications or tablets is an indispensable routine for a vast number of people. Ensuring the accurate quantity and adherence to stipulated frequencies often holds significance for the health and wellness of an individual. Conventional methodologies, such as pill organisers, are commonly employed to streamline and manage daily intakes. However, these manual strategies are susceptible to a myriad of drawbacks, including dosing inaccuracies, inadvertent omissions and the inconvenience of administration. Such pitfalls become accentuated for people with diminished motoric or cognitive capabilities, like the elderly, necessitating external intervention for dosage management.

[0007] Traditional pill organisers and semi-automated pill dispensers present short comings. Manual organisers demand frequent replenishments, a task that not only consumes time but also necessitates manual dexterity. The inflexibility of these methods is evident in their preset capacities that do not lend themselves to easy modifications. Moreover, the actual act of dispensing from such organisers can prove arduous, exacerbating the risk of missed intakes.

[0008] Transitioning to a fully automated system for tablet dispensation encompassing timed dosing, meticulous counting, and precise dispensation could help to eradicate the limitations of manual or semi-automated apparatuses and has the potential to markedly enhance the efficacy of medication and tablet intake. However, devices in the prior art, striving to achieve this level of automation, often resort to intricate mechanisms, elaborate components, and sophisticated control systems. The resultant devices are not only economically prohibitive but also command substantial spatial real estate, are prone to mechanical obstructions, and lack modularity, thus inhibiting the adaptation of reservoir sizes or variation in medication types. Consequently, these complexities act as deterrents, limiting their widespread adoption when compared against their manual or semi-manual counterparts.

[0009] It would be desirable to provide an object dispensing device for objects such as tablets that overcome or at least ameliorate some of the problems of the prior art, or which provides a useful alternative.

[0010] Summary of invention

[0011] In a first aspect there is provided an object dispensing container for dispensing small objects such as tablets, comprising; a body defining an internal volume for storing objects; an outlet for dispensing a plurality of the objects from the body; a chute for moving the plurality of the objects from the internal volume to the outlet; a frame for supporting the body during use; wherein the body is tippable while mounted in the frame from a stored position to a dispensing position; and wherein in the dispensing position, the chute of the body is inclined so that the plurality of objects slide from the internal volume of the body, down the chute and are dispensed at the outlet, and following dispensing, the body tips back to the stored position.

[0012] In an embodiment, vibration is applied to the chute during dispensing to separate the plurality of objects from one another as they slide down the chute so they exit through the outlet individually, one by one. In an embodiment, one or more sensors are positioned near the outlet for detecting and counting the number of objects dispensed.

[0013] There exists no inherent limitation on the size of objects with which the device can operate. The dispensing system is particularly applicable for small objects, such as medications or tablets. However, it can be scaled to accommodate larger items, including but not limited to tennis balls, basketballs, bottles, nuts and bolts, recyclables, and briquettes. The dimensions of the device should be proportioned based on the largest object intended for dispensing and counting. While the system is versatile, it is most effective when the size range of objects does not exceed a ratio where the smallest object is more than twenty times smaller than the largest, as exceeding this ratio may compromise counting accuracy. The system is optimally suited for discrete objects requiring individual counting. Although powders or granular materials like sand can be handled, modifications to the counting mechanism are necessary for accurate dispensing of such substances.

[0014] The objects compatible with the dispensing system can generally be of any shape, provided the aspect ratio does not significantly exceed 10; that is, the objects are not substantially longer than they are wide. Elongated, slender objects are typically unsuitable due to their propensity to interlock, which impedes smooth flow through the system. Ideal shapes include all forms of pills or tablets intended for human or animal consumption, as these are designed for ease of ingestion and naturally facilitate flow within the device. Other suitable objects encompass bolts, nuts, washers, balls, seeds, aggregates, rocks, pellets, small confectioneries, edible gummies, mints, and similar items.

[0015] A notable advantage of the device is its ability to accommodate varying sizes and shapes of objects without requiring physical adjustments or software modifications, provided the objects fall within the specified size parameters of the device. The system's capability to handle a handful of objects and accurately count them as they exit eliminates the necessity for manual recalibration or reconfiguration when switching between different object types. This feature allows the device to process multiple shapes and sizes simultaneously. For instance, if two different types of tablets are mixed together, the device can dispense and count them without differentiation or the need for separate settings. This flexibility is particularly beneficial in medication dispensing applications, where a variety of tablet types and sizes may be present, ranging from probiotic gummies to small, halved medication tablets.

[0016] The device is capable of dispensing any required number of objects. In a typical operation, the chute is filled with approximately three to ten objects during a single tipping action. These can be counted individually as they are dispensed. Upon reaching the desired quantity, the dispensing sequence can be halted, returning any remaining objects in the chute back to the container. If a greater quantity is needed, the device performs multiple refilling and tipping cycles to achieve the specified count. This functionality is especially effective in managing medication regimens where varying dosages are often necessary.

[0017] The material properties of the objects, such as friction coefficient, hardness, and colour, generally do not adversely affect the device's operation. The primary exception is the stickiness of the objects. Items that naturally adhere to each other and require significant force to separate are unsuitable for processing through the system, as they do not flow freely and cannot be reliably separated for individual dispensing. Examples of such objects include certain dried fruits and sticky candies, which tend to clump together and adhere to the device's internal surfaces, disrupting the flow mechanism. However, treating these objects with an anti-caking agent has been found effective in mitigating stickiness, allowing them to be used with the system. Additionally, environmental factors such as humidity can influence the stickiness of certain objects, such as gel capsules or fish oil tablets. These objects are not inherently sticky under normal conditions but may become so upon absorbing moisture. Therefore, it is crucial to control moisture levels within the device, employing measures such as desiccants or sealed containers to maintain optimal operating conditions for these types of objects.

[0018] The container serves as a storage means for the objects. The container can store the objects prior to them being dispensed.

[0019] In embodiments designed for smaller objects, such as medications or tablets, the container may be constructed from materials including, but not limited to, polyethylene (PE), polypropylene (PP), or other suitable materials known for costeffectiveness and lightweight properties. The container may incorporate the chute, motors and electronic components within its structure.

[0020] The container can assume various shapes, including cylindrical, rectangular, or any geometry that facilitates efficient storage and dispensing. A rectangular configuration may be particularly advantageous due to its space-efficient design. In the case of a rectangular container, it may include a guiding means to direct objects towards the internal chute entrance such as small lead-in curve or tapered section. This design feature prevents the formation of dead zones where objects might accumulate and remain undispensed.

[0021] The container's size can be scalable to accommodate the required quantity of objects. The minimum dimensions of the container are determined by the size and flow characteristics of the objects to be dispensed, ensuring that the objects can mix and move freely within the storage area. The maximum size is typically constrained by the capacity of the drive actuator; larger containers necessitate more powerful motors or actuators. Therefore, there is an optimal container size corresponding to each type of motor or actuator employed. This adaptability is particularly advantageous in applications such as tablet dispensing, where the quantity and size of objects may vary, for example, a container can be dimensioned smaller for dispensing tiny medications taken once per day versus larger capsules taken multiple times per day.

[0022] In an embodiment, the container is enclosed and the objects are preferably not taken from the container other than by dispensing. The container is not an open tray. In embodiments where the objects are medications or tablets, it is generally desirable for the container to be well-sealed against moisture ingress to preserve the integrity and shelf life of the contents. This sealing is facilitated by the minimal number of openings required in the container's design. Necessary openings may include an access point for loading additional objects, which may be equipped with a locking mechanism to prevent unauthorised access; the exit point / outlet of the chute for dispensing objects; an aperture for electrical connections, such as power cables entering the container; and / or an opening for the motor or actuator shaft to exit the container. These openings can be fitted with appropriate seals, gaskets, or other sealing mechanisms to minimise moisture ingress.

[0023] The outlet of the container is sized and shaped to allow for objects to be dispensed from the container body. The outlet is at the end of the chute in the container body.

[0024] Integrated within the device is a chute assembly designed with the aim of facilitating the controlled movement, separation, and dispensing of objects from the container to the outlet. A plurality of the objects can move along the chute with the intention that the objects are dispenses one by one at the outlet.

[0025] The chute can have any cross sectional shape. In an embodiment, the chute has a predominantly V-shaped cross-sectional profile, which has been found to be highly effective in aiding unobstructed flow and separation of items. While a concave design is favoured for the chute, alternative profiles such as ribbed, textured, or convex configurations may also be implemented without departing from the scope of the invention.

[0026] The chute aims to serve multiple functions: it allows a limited number of objects from the container to be processed, facilitates their separation as they progress towards the exit point, and helps to ensure accurate counting as the objects are dispensed from the system. The chute is characterised by a length, with an entrance point at the lower end for receiving objects from the container and an exit point at the outlet for dispensing the objects.

[0027] Although the chute and container typically tip as a single unit, alternative configurations allow them to operate independently. In cases where a substantial quantity of objects needs to be stored, it may be impractical for the container to tip along with the chute. In such embodiments, the container can remain stationary while the chute, mounted externally and tips independently. The functionality remains substantially similar, with the chute receiving objects through an aperture in the container rather than being enclosed within it. As the chute tips, it naturally seals against the exterior of the container, maintaining the integrity of the storage environment. In this embodiment, the body defining the internal volume for storing objects can be the chute storage area.

[0028] The container body may be separable from the chute or integrally formed as a single piece with the chute. This modularity allows for versatility in design, enabling one chute to be used with multiple containers or one container to interface with multiple chutes, depending on application requirements. It may be advantageous to have a detachable chute for maintenance or to accommodate different object types without necessitating a complete redesign of the container.

[0029] At the lowest part of the chute located at the bottom wall of the container, an opening (or internal chute entrance) is provided to allow objects to enter the chute from the container's internal volume. This opening may be open on multiple sides (e.g., top and side) or on a single side, depending on the arrangement of stored objects and the desired flow characteristics. For optimal compactness and efficiency, it has been found advantageous to locate the chute adjacent to one side of the container, allowing objects to enter the internal chute entrance through the side of the chute. This configuration can improve the flow dynamics within the storage area by preventing the chute from obstructing the central area, thereby enhancing the overall compactness of the design and simplifying the loading process, as objects need only be concentrated on one side of the container.

[0030] The dimensions of the internal chute entrance can be selected for proper operation. The opening must be sized to admit a sufficient number of objects for dispensing, based on the largest object intended to be processed by the system. For applications involving medication, it is desirable for the chute to accommodate approximately two to five of the largest objects simultaneously. This capacity allows multiple tablets to be dispensed in each tipping cycle, enhancing efficiency. If the chute were optimised to admit only a single object, multiple tipping cycles would be required to dispense several tablets, reducing operational efficiency. In cases involving smaller tablets, a greater number may enter the chute; however, due to their reduced size, they can still be effectively separated prior to reaching the outlet. The chute's area-based entrance naturally regulates the number of objects entering, maintaining a consistent volume that facilitates separation. It is thought to be important to avoid sharp edges and corners at the internal chute entrance, as these can impede the natural flow of objects into the chute.

[0031] Once inside the internal chute entrance, the area where the objects are located may be referred to as the chute storage area. This area serves as a temporary holding space for objects ready for dispensing. The chute storage area can be designed to be wider than the main chute by incorporating a funnel-shaped expansion that channels objects back into the narrower chute pathway. The walls of the chute storage area must be of sufficient height to prevent objects from escaping back into the main storage area of the container. The required wall height depends on factors such as the overall dimensions of the chute and the operational speed of the motor or actuator. Higher motor speeds can cause objects within the chute storage area to bounce, necessitating taller walls to contain them. Some bouncing of objects is acceptable provided the desired number remains within the chute storage area. It is noted that as the storage area becomes less full, the load on the motor decreases, potentially increasing its speed and exacerbating bouncing. Therefore, speed control mechanisms may be necessary to maintain consistent motor operation and prevent undue bouncing, especially when attempting to dispense all remaining objects from the device.

[0032] In the stored position, where the chute and container are oriented vertically with respect to their longitudinal axes, objects within the container may flow naturally through the internal chute entrance into the chute storage area. For larger objects, or when the chute requires additional filling, the container and chute may be tipped slightly backward and agitated to facilitate loading into the chute storage area. This agitation may assist in overcoming any static friction or interlocking tendencies of larger objects.

[0033] A feature of the design, in an embodiment, is an ability to prevent overaccumulation of objects within the chute storage area. This self-regulating property is inherent to the design as in the stored position, objects are directed towards the internal chute entrance effectively blocking additional objects from entering. This directing effect may be aided by incorporating a curve at the base of the chute pointing towards the entrance. The curve towards the internal chute entrance pushes the objects towards the entrance making sure they experience more resistance from entering. This design helps to ensure that the chute cannot become overfilled, which could compromise dispensing accuracy and increase the risk of jamming.

[0034] Once there are objects in the chute storage area, the container and chute assembly are tipped downward into the dispensing position. In this orientation, the objects in the main storage area of the container shift away from the chute entrance due to gravity, preventing additional objects from entering the chute during the dispensing cycle. This isolation ensures that only the objects already within the chute are processed during the separation and counting steps, enhancing accuracy and reliability. While there may be a maximum fill level for the container to ensure this functionality, the design allows for relatively high fill levels, particularly when the chute entrance is positioned in a corner (e.g., the back left corner) of the container.

[0035] As the container is tipped and gravity acts upon the objects within the chute storage area, the objects begin to move towards the outlet. The objects can slide down the chute to the outlet. A plurality of objects are moved along the chute for dispensing.

[0036] During dispensing there can be dispensing assistance. The dispensing assistance can be in the firm of agitation. The agitation can be vibration applied to the chute. Vibrational motion is typically initiated to aid in breaking up any clusters of objects and promoting individual movement. This vibrational assistance can commence when the chute reaches an angle of approximately 90 degrees from vertical. From this point, the container may continue to tip further, but at a slower rate, to allow the objects to receive increased gravitational force while maintaining controlled movement towards the outlet.

[0037] As the objects progress along the chute, they enter a "separation zone" of the chute. This zone can comprise a shaped cross-section such as a V-shaped crosssection, which can be effective in separating individual objects. Alternative profiles such as flat or concave shapes may also be employed; however, a V-shape has demonstrated superior performance. A 90-degree V shape with a radius from the base of the V larger than the maximum of the object has been found to be advantageous. The transition from the chute storage area, which may be relatively flat, to the separation zone is smooth and free of sharp changes to prevent obstruction. It may be advantageous for one side of the transition between chute storage area and separation zone to commence before the other, imparting a turning force on elongated objects and facilitating their alignment on the chute.

[0038] Occasionally, two objects may enter the separation zone in a stacked configuration. Typically, as they advance down the chute, they will separate and continue individually. In instances where the separation zone is not sufficiently long, larger objects may remain stacked throughout their progression. To address this, in embodiments, a small wall or obstruction can be incorporated at the end of the separation zone to dislodge the upper object, allowing both to continue separately. Care must be taken in designing such features to avoid creating wedge scenarios that could lead to blockages; thus, walls should not be staggered or decrease in height along the chute's length.

[0039] At the conclusion of the separation zone, prior to the outlet there is an exit zone. The exit zone is a steeper section of the chute that may accelerate the objects prior to their departure from the chute. This acceleration increases the spacing between successive objects. Having increased spacing may facilitate accurate counting and may enable the system to halt the dispensing process promptly once the desired number of objects has been released.

[0040] The outlet from which objects are dispensed from the chute is sized to be larger than the largest object intended for dispensing. In an embodiment, the outlet is at least two or three times the object's diameter (or longest dimension). This sizing ensures that objects do not collide with the outlet exit aperture, which could impede their movement and negatively impact counting accuracy. Any restrictions at the outlet should be avoided to maintain unobstructed flow.

[0041] In embodiments, the chute's design allows it to dispense multiple objects individually in a repeatable and accurate manner. This capability enables efficient dispensing without the need to reload the chute from the container's storage area after each object, enhancing overall efficiency. Furthermore, the chute's open and adaptable nature permits it to accommodate objects of various sizes and shapes (within the designed maximum), eliminating the need for physical adjustments or control system changes when switching between different object types. This feature is particularly advantageous in applications involving medications or tablets, where a wide range of sizes and shapes must be dispensed reliably.

[0042] The materials used for the chute should possess low friction properties to facilitate the smooth sliding of objects. The selection of material may depend on the type of objects being dispensed. Common plastics such as polypropylene (PP), polyethylene (PE), acrylonitrile butadiene styrene (ABS), and polylactic acid (PLA) have been found suitable for medication tablets. Over time, wear from the objects may increase friction; in such cases, harder materials like polished steel or ultra- high-molecular-weight polyethylene (LIHMWPE) may be employed. Protective coatings or tapes may also be applied to the chute surfaces to maintain low friction characteristics. Dry and wet lubricants may be utilized to improve flow and reduce friction within the device. However, in applications involving food contact or storage, any lubricants used should be food-grade and comply with relevant safety regulations to prevent contamination of the dispensed objects.

[0043] It is desirable to minimise the static friction coefficient of the chute material rather than the sliding friction coefficient. Materials such as polytetrafluoroethylene (PTFE), commonly known as Teflon®, may exhibit higher static friction compared to UHMWPE or PLA, which can be problematic, particularly with gel capsules that tend to adhere to certain surfaces. In some instances, ribbed or rough textures on the chute surface may slightly reduce static friction, although not always to a meaningful extent. When gel capsules absorb moisture, their stickiness increases significantly, potentially impairing the chute's functionality. Therefore, controlling moisture ingress into the container is essential. The use of anti-caking agents may also be effective in reducing friction when moisture cannot be entirely avoided. The chute's length is determined by the size of the objects being dispensed. Generally, longer chutes are more effective at separating items, with a length of approximately three, four or five times the length of the object being sufficient. Increased vibration during dispensing can compensate for shorter chute lengths if necessary. The width of the chute should also correspond to the object size, ideally being at least two, three or four times wider than the width of the object. Preferably, the chute does not taper inward toward the exit, as this could create points of constriction where blockages may occur.

[0044] The chute may be designed to be removable to facilitate cleaning or maintenance procedures. Depending on the specific application, the chute and / or container may be constructed to be disposable or to incorporate disposable liners, thereby reducing the risk of contamination and simplifying upkeep.

[0045] The device incorporates a frame designed to support the container or multiple containers, suspending it / them above the surroundings and allowing for controlled tipping motion relative to the frame. This configuration enables the container or containers to transition between various positions necessary for the dispensing operation. An actuator, which may be housed either inside or outside the container / containers, provides the requisite tipping motion.

[0046] In an embodiment, the range of motion required during tipping is about 180 degrees. The container's vertical orientation comprises the storage position. An inclination of about 10, 20 or 30 degrees backward from vertical can represent a chute loading position. During operation, the container or containers tip forward until the chute reaches an approximately horizontal (flat) position, initiating the dispensing sequence. Subsequently, the container continues to tip to the dispensing position in which the chute is at a steeper angle, approximately an additional 15, 20 or 25 degrees past horizontal. A vibrational motion can be applied during dispensing. Once objects have been dispensed, the dispensing cycle is complete.

[0047] The initial tipping angle required for objects to begin exiting the chute may vary based on the material properties and shapes of the objects. Objects with higher static friction, such as fish oil capsules, may require a larger initial tipping angle compared to harder, powder-based tablets. Generally, the higher the static friction of the object, the larger the initial tipping angle needed. To accommodate a range of object types, it is acceptable to start at a smaller absolute tipping angle and reduce it over time. However, this approach may increase the dispensing time by up to 60 seconds compared to immediately tipping to the optimal angle. If rapid dispensing is critical, specific tipping profiles or angles can be stored for different objects to optimise speed. These profiles can be determined automatically during normal dispensing operations, with the device resetting and recalibrating when different objects are introduced. Additional sensors or cameras within the chute may also be utilised to dynamically adjust the tipping angle without relying on preset values.

[0048] For the dispensing of tablets, a typical operation involves tipping the chute from a vertical position to a horizontal (flat) position through a 90-degree movement, initiating vibration, and then continuing to tip the container by approximately 20 degrees over 60 seconds. Tipping too rapidly during this phase can result in objects leaving the chute in close succession, making it difficult to halt the flow promptly and potentially leading to overdosing.

[0049] Upon completion of dispensing, the actuator can return the container (and chute) to the stored position. The return of the container is by retracing the path that the container took from the stored position to the dispensing position. The container tips backwards and forwards. The container can be returned to the stored position by active driving. The container can return to the stored position under the influence of gravity.

[0050] In applications involving smaller objects, a servo motor with significant gear reduction is suitable for providing the tipping motion necessary to tilt the container or containers relative to the frame. The container or containers may be supported on both sides by the frame or, alternatively, supported solely by the actuator shaft, depending on specific design requirements.

[0051] Alternative actuators may be employed based on the scale and operational needs of the dispensing system. These actuators include, but are not limited to, stepper motors, linear actuators, pneumatic actuators, and hydraulic actuators. Stepper motors offer precise control over angular position without the need for feedback systems, making them suitable for applications requiring high positional accuracy. Linear actuators may be advantageous in designs where linear movement is preferred over rotational motion, providing smooth and controlled tipping action. The selection of the actuator has an impact on the overall design, efficiency and reliability of the dispensing system. Factors such as torque capacity, speed, precision, power consumption, and response time must be considered. Actuators with higher torque capabilities can handle larger containers or heavier loads, enhancing the system's scalability. Energy-efficient actuators contribute to reduced power consumption, which is critical for battery-operated devices or systems aiming for sustainability. The precision and responsiveness of the actuator influence the accuracy of the dispensing process and the system's throughput, thereby affecting overall reliability.

[0052] To prevent overheating of the actuator, especially during continuous or high- frequency dispensing operations, thermal management solutions can be integrated into the system design. These solutions may include heat sinks attached to the actuator housing to dissipate heat effectively. Incorporating cooling fans or forced- air convection systems can enhance heat dissipation. Duty cycle limitations may be employed, wherein the actuator operates intermittently rather than continuously, allowing sufficient cooling periods between operations. Thermal sensors can monitor the actuator's temperature in real-time, enabling the control system to adjust operation parameters or initiate cooling measures proactively.

[0053] In small-scale embodiments, motors may be selected or configured to self-limit the generated forces, obviating the need for protective guarding. In larger-scale applications, the dispensing system may include safety guards to prevent personnel injury and may be equipped with emergency stop mechanisms, enabling immediate cessation of all operations in the event of an emergency.

[0054] The device can be powered through various means to accommodate different operational environments and user requirements. Battery operation enables portability and mains power operation provides a reliable power source for stationary installations. A combination of power sources may be advantageous; for example, using mains power to drive the control system and dispensing mechanisms while incorporating a battery backup for critical functions such as maintaining a real-time clock for timing control during power interruptions.

[0055] Advanced control algorithms may be implemented to optimise actuator performance, including the management of acceleration and deceleration profiles to reduce mechanical stress and enhance precision. In critical applications, redundant actuators or parallel systems may be incorporated to ensure continued operation in the event of a component failure, thereby enhancing system reliability. Actuators and associated components may be enclosed or sealed to protect against contamination or unintended contact with the objects within the container.

[0056] The tipping motion of the container alone may be sufficient to cause dispensing. In some embodiments the dispensing may be assisted. The assistance can be by vibration. The vibration can help to ensure that objects exit through the outlet of the chute individually. The vibratory or shaking mechanism may be implemented through the main actuator responsible for tipping or via a dedicated vibration motor, such as those commonly used in mobile devices.

[0057] For applications involving medications and tablets, using the main tipping actuator to generate the required vibratory motion is generally sufficient to achieve effective separation of the objects. However, employing the main actuator in this manner can significantly increase its current consumption, potentially leading to overheating during continuous or prolonged dispensing operations without adequate cooling mechanisms. As such, for applications requiring continuous or frequent dispensing, the inclusion of a separate vibration motor is advantageous to prevent overheating and ensure reliable operation. In household settings where dispensing events occur infrequently, such as a few times per day, the risk of overheating is minimal, and the main tipping actuator may suffice.

[0058] When the vibration or shaking is generated by the main tipping actuator, there will be a "low vibration zone" within the chute. As objects travel down the chute, they pass through a point closest to the axis of the tipping motion, where the vibrational force exerted on the objects is significantly reduced compared to areas further from the tipping axis. Since vibrational force is critical for breaking up clusters of objects and ensuring individual separation, it has been found beneficial to position the pivot point of the tipping motion slightly above the midpoint of the container. This adjustment shifts the low vibration zone toward the exit point / outlet of the chute, where the objects are already more separated, thus enhancing the overall effectiveness of the vibration mechanism.

[0059] To ensure the integrity of the dispenser against external elements, particularly to prevent moisture ingress and contamination, the container may comprise a selfsealing lid mechanism. This lid can be activated through various means, including electromechanical actuation, gravity, the inherent motion of the container or a combination thereof.

[0060] Actuators, responsible for sealing mechanisms, are typically of a smaller scale compared to those used for the primary tipping movement. Their compact size allows for integration without significantly increasing the device's overall dimensions or power consumption. Employing a powered sealing method can enhance sealing integrity by exerting additional force on the sealing surfaces, thereby improving the effectiveness of the seal. This method, although requiring further powered components, provides greater control over the sealing process and ensures consistent performance across varying operational conditions.

[0061] An embodiment of a gravity-based self-sealing lid involves the use of a rotating paddle equipped with a counterweight. This paddle is configured to move between the container lid and the chute when the container is tipped backward into the storage position, thereby blocking the outlet of the chute. In this configuration, the stored position of the device is slightly inclined backward from the vertical to utilise gravitational force acting on the counterweight, which maintains the paddle in the sealing position. When the container is returned to the vertical orientation, the weight of the counterbalance exerts force on the paddle, pressing it against the lid opening and enhancing the seal. This gravity-driven self-sealing lid is particularly advantageous in systems comprising a single chute and container, as it obviates the need for additional motors or actuators dedicated to sealing functions. Each unit operates independently, with the act of tipping back both stopping the flow of objects and actuating the seal.

[0062] An alternative embodiment employs an electromechanical seal, which may consist of a rotating paddle arrangement or a paddle connected to a solenoid or other actuator. Using a powered sealing method is especially beneficial in configurations where multiple chutes and containers are attached to a single tipping motor. In such cases, the powered sealing mechanism can selectively shut off the flow from individual chutes while allowing others to continue dispensing. This approach reduces the number of components required to dispense multiple different objects, as it eliminates the need for multiple tipping motors and allows for centralized control of the sealing function.

[0063] A further application of an electromechanical seal is in the verification of the dispensed objects prior to their release to the tray or conveyor. For instance, immediately downstream of the outlet, there may be a small continuation of the chute where the dispensed item resides temporarily. After an object is detected by the main sensor, the exit point can be sealed off, and a secondary verification system, such as an additional sensor, camera or weighing mechanism, can be used within this continuation section to confirm the dispensed count and ensure dosage accuracy. Once verification is complete and the dosage is confirmed to be correct, a subsequent seal or gate can be actuated to release the dose to the tray or conveyor for collection. Otherwise, if incorrect the dose can be returned to the container.

[0064] The sealing surfaces may incorporate airtight or moisture-resistant elements, such as silicone or rubber gaskets. The selection of materials for the seals should be compatible with the objects being dispensed to avoid contamination or adverse reactions. Design and testing procedures can be conducted to ensure compliance with relevant industry standards, such as Ingress Protection (IP) ratings, which certify the level of protection against dust and moisture ingress.

[0065] At the exit of the container, a detection system comprising one or more sensors, one or more cameras or a combination thereof, can be employed to accurately quantify the dispensed objects. As objects pass individually through the outlet, they enter a detection zone, where they are counted and, if necessary, examined for verification purposes. Given that the chute is capable of accepting and dispensing multiple objects of varying shapes and sizes, it is critical for the sensor arrangement to accurately count the objects, providing essential information to the control system. This data enables the control system to determine whether the target dispensing quantity has been achieved and whether to cease further dispensing. Additionally, the detection system may be used to verify attributes of the objects, such as colour or size, ensuring that the dispensed items meet expected criteria. A camera-based system may be incorporated to enhance verification capabilities.

[0066] The device may include an automatic shut-off mechanisms that activate when obstructions or issues are detected. The control system can continuously monitor the dispensing process, and upon detecting anomalies such as blockages or unexpected object flow, it can initiate corrective actions, including halting the dispensing operation and or providing alerts to the user or operator.

[0067] For applications involving the dispensing of medications and tablets, an ultraviolet (UV)-capable phototransistor paired with a UV light-emitting diode (LED) in a pass- through arrangement, mounted vertically above and below the chute exit, can be most effective. Ultraviolet light is particularly suitable due to its strong absorption by oils present in gel capsules, allowing for reliable detection of such objects. In contrast, infrared wavelengths are often transmitted through gel tablets and are less effective for detection purposes. Alternative sensor technologies, such as infrared reflectance sensors and time-of-flight distance sensors, have not demonstrated favourable results in this application due to the rapid transit of objects through the detection zone and the need for immediate feedback. Objects may pass through the detection window within timeframes as short as 20 to 100 milliseconds, necessitating sensor systems with fast response times to ensure accurate counting.

[0068] Calibration of the sensor system is typically not required but may be necessary at periodic intervals or in some cases when dispensing different types of objects. Typically, such calibration is performed by the manufacturer prior to shipping or during scheduled maintenance. Provisions may also be included for automatic calibration during operation, allowing the device to maintain accuracy without manual intervention.

[0069] The central control system maintains real-time tracking of the dispensed object count against a predefined target quantity. Upon reaching the requisite count, the control system can halt the dispensing protocol by promptly initiating the tipping back of the container to the stored position. The return tipping action can be rapid to prevent additional objects from being dispensed beyond the target count. In applications using servo motors, the required speed for tipping back can be readily achieved.

[0070] The detection zone is located close to the exit point / outlet of the chute. This ensures that objects, once detected, promptly exit the chute, minimising the likelihood of multiple objects passing through the detection zone before the system can react. Relying on delays or compensating for larger distances between the detection zone and the exit point may reduce counting accuracy, as additional objects could pass through during the delay period, potentially leading to overdispensing.

[0071] The device may further incorporate additional sensors and / or cameras to monitor the quantity of items remaining within the container. This information can be used to initiate restocking processes or alert the user when restocking is required. The alert relating to the contents of the container, and a requirement for restocking can be one or more of visual indicators, audible alerts, or notifications transmitted to connected devices. Alternatively, the container may include a transparent or translucent window, allowing the user to visually assess the remaining quantity of items.

[0072] Upon dispensing, the objects can be directed to a collection medium. The collection medium can be trays, chutes (which may be inclined), or conveyors. In embodiments with powered conveying, a separate motor or actuator powers the movement, facilitating the transport of the objects toward the end of the conveyor for easier collection, distribution to multiple users, or rejection of dispensed objects that are not collected within a predetermined time frame.

[0073] In configurations employing a tray, the tray can be positioned slightly below the outlet of the chute, at a distance sufficient to prevent interference with the tipping motion of the container. The tray serves as a receptacle for the dispensed objects. To prevent the objects from bouncing out upon impact, the receiving surface of the tray can include walls or barriers. The height of these walls can be reduced by using materials with high friction coefficients and impact absorption properties, such as silicone, on the tray surface.

[0074] The objects may be transferred to subsequent stages in the overall process either manually or through automated means. In applications involving medications, the tablets dispensed onto the tray can be made readily accessible for the user to retrieve and consume. In these cases, the user may collect the items by using a swiping motion. Alternatively, the tablets may be conveyed to a central collection point for further handling, such as being placed into a cup for immediate consumption or being packaged into a wrap or container for later use.

[0075] Visual indicators, such as lights, device notifications or auditory signals may be employed to alert the user when items are ready for collection. In the context of medication dispensing, it is advisable for the user to collect the tablets within a specified timeframe, typically within a few hours, to prevent moisture absorption that could compromise the integrity of the medication. In embodiments utilizing a conveyor system, it is possible to implement mechanisms that reject or redirect items that have remained uncollected beyond the designated time period, thereby maintaining the efficacy of the dispensed items.

[0076] The tray or conveyor may be equipped with protective enclosures or guards to restrict direct access to the dispensed objects. Such measures serve to prevent unintended access by unauthorised individuals, such as children, and to ensure that only authorised personnel can retrieve the objects. Sensors and / or cameras may be integrated to detect whether the objects have been removed from the tray or conveyor. This information can be relayed to the control system to update the dispensing status and, if necessary, to trigger subsequent actions or alerts. The device can be designed with the capability to interface with external systems, including inventory management systems, electronic medical records (EMR), and automated packaging equipment. This integration enables seamless communication and data exchange, facilitating functionalities such as automated inventory tracking, prescription verification, dispensing history logging, and compliance monitoring.

[0077] Once the objects are presented to the tray or conveyor, additional verification processes may be implemented to ensure the accuracy and integrity of the dispensing operation. Sensors such as cameras can perform visual inspections to confirm the count, identify object characteristics (e.g., shape, size, colour), and detect any anomalies or foreign objects. Weight sensing mechanisms can be employed to verify the total mass of the dispensed objects, providing an additional layer of confirmation for the object count and detecting discrepancies that may indicate dispensing errors.

[0078] Data from these verification processes can be communicated to the control system, which can take corrective actions if necessary, such as initiating an alert, rejecting the batch, or adjusting future dispensing operations.

[0079] The container is designed to be refillable through a manual procedure involving the opening of an access portal, such as a screw-top lid or flip top lid, allowing users to pour additional items into the internal storage volume. This compartment may be lockable to only allow access by an authorised person. In alternative commercial embodiments, automatic refilling may be facilitated via a bulk hopper system situated above the main container, providing continuous replenishment of objects without the need for manual intervention.

[0080] Refilling may involve the use of replaceable containers or cartridges that fit within the main container, or specialised packaging designed to reduce the risk of crosscontamination between different units or types of objects. The system may incorporate scanning technology, such as barcode or RFID readers, to facilitate the refilling process, potentially including electronic unlocking of compartments or verification of container contents.

[0081] During refilling or the dispensing sequence, the container may be momentarily open, potentially allowing moisture to enter. To mitigate this, the container and / or chute may include dedicated compartments or cavities for housing desiccant materials. In larger-scale devices, a powered dehumidifier could be employed to maintain low humidity levels within the container. Depending on the properties of the objects being dispensed and the prevailing environmental conditions, temperature control may be necessary to safeguard the integrity of the contents. Such temperature control can be implemented by placing the entire device within a controlled environment, such as a refrigeration unit, or by incorporating supplementary devices such as dedicated refrigeration circuits, electric heating elements, or thermoelectric cooling systems. With adequate moisture and temperature protection, sensitive objects like medications can be stored within the container while maintaining a shelf life comparable to their original packaging. It may also be desirable to add humidity / temperature sensors or indicators to monitor the environment.

[0082] During the dispensing process, the vibration of objects can result in the generation of noise. To mitigate this, dampening materials may be incorporated within the container to reduce acoustic emissions. Additionally, damping mechanisms may be applied to the frame to attenuate vibrations transmitted to the surrounding environment, thereby preventing unwanted movement or shaking of the device.

[0083] The dispensing system can includes an interactive control interface, which may comprise physical components such as buttons, displays and touchscreens as well as digital interfaces such as mobile applications or web portals. The device may be configured to receive and use additional data from the user's devices, such as location information indicating whether the user is at home or alarm times set on a smartphone. This data enables the dispensing system to adjust its operation based on the user's habits or presence, providing a more personalized and efficient dispensing experience. This interface empowers users to customize dispensing parameters, including timing, quantity, and frequency of dispensation. Embedded sensors or the aforementioned detection systems can relay data regarding the remaining count of objects within the container to the control system, enabling realtime monitoring and adjustments.

[0084] To restrict access to the dispensed objects or dispensing settings, user authentication mechanisms such as personal identification numbers (PIN codes), biometric verification (e.g., fingerprint or facial recognition), or secure login credentials may be implemented.

[0085] The system may alert users when the container is running low on items through visual indicators (e.g., LED lights or on-screen notifications), audible alarms, or alerts sent to connected devices like smartphones or computers. Additionally, the device can receive software or firmware updates, either via wired connections or wirelessly, to add new features, improve performance, or enhance security protocols. Potential integration with smart home systems or Internet of Things (loT) platforms allows for expanded functionality, such as voice control, remote monitoring, and automated reordering of items when supplies are low. The device may also connect to other apparatuses, such as water dispensers or complementary dispensing systems, to provide coordinated functionality and enhance user convenience.

[0086] The system may be modular, which permits the integration of multiple units to accommodate varied dispensing requirements. Electrical connectors can be employed to enable both power delivery and communication between stacked modules. Mechanical connections, such as dowels or clips, may be used to enhance the structural integrity of the assembled units.

[0087] It is advantageous for the connectors to incorporate small electrical components that enable the detection of each module's position within the modular assembly. For example, diodes with resistors driven from the main power supply have been effectively used for this purpose. This configuration eliminates the need to manually set up or program each device's location within the stack. Each device may be assigned a unique identification number or code, enabling individualised dosing, timing, and settings adjustments from the main control system or a centralized management platform. To further enhance modularity, it is beneficial to include all necessary electronics and processors within each individual unit. This design allows each device to function independently, negating the requirement to route all signals and power back to a central unit. In embodiments employing wireless communication protocols, such as Bluetooth, it is advantageous for the first device in the stack to assume the role of a master device. This master device manages communication with external devices, such as smartphones or network systems, and distributes control signals, timing information, and other necessary data to the subordinate devices. Communication between devices can be facilitated through the physical connectors or via wireless protocols.

[0088] Modularity affords users the flexibility to augment the base unit with additional modules, potentially of diverse scales, to meet multifaceted dispensing requirements. Connector systems are designed to seamlessly integrate these units, whether they are arrayed adjacently, oppositely, or in stacked configurations. This modularity enhances the commercial viability of the device, particularly in the dispensing of medications or tablets, as it allows for customisation based on the varying number of different tablets required by users, which may change from person to person and over time.

[0089] A wide range of configuration options are available to the user for arranging the stacking of modules, depending on available space and specific requirements. Users may mix devices of different capacities or functionalities within the system. The modular design and standardised connections enable integration with various other products, including technologies such as water dispensers or powdered supplement dispensing systems, thereby enhancing the system's versatility and adaptability to user needs.

[0090] The present invention, while primarily focused on medication dispensing, is not limited to this application. The fundamental design and operational principles are adaptable to a wide array of object dispensing scenarios across both domestic and industrial settings where precise unit quantities are required.

[0091] Examples of such applications include, but are not limited to; • Industrial Assembly Processes: Dispensing and counting of nuts, bolts, washers, and other fasteners in warehouse environments to streamline assembly operations;

[0092] • Chemical Industry: Dispensing specialized pellets or granules where accurate dosing is critical for chemical reactions or processes;

[0093] • Food and Beverage Production: Dispensing rennet tablets into vats for cheese manufacturing, ensuring precise quantities for consistent product quality; and

[0094] • Veterinary and Animal Care: Dispensing medication for pets or livestock, where accurate dosing is essential for animal health.

[0095] The present system, in embodiments, offers high counting accuracy, particularly in applications involving medications and tablets. This precision is achievable even with simple, low-cost components, enhancing the device's practicality and affordability. The system’s ability to be integrated into compact spaces may allow for the development of small-scale devices suitable for various environments.

[0096] In embodiments, the simplicity of the control system, which does not inherently require advanced techniques such as computer vision, contributes to the device's reliability and ease of use. This straightforward control architecture may reduce production and maintenance costs, making the system highly viable for commercial, consumer and industrial applications.

[0097] The present system is, in embodiments, highly scalable and adaptable. It can accommodate a wide range of object sizes, quantities of stored objects, and different types of objects without significant modifications. This adaptability ensures that the system can meet diverse operational requirements, enhancing its commercial appeal and versatility compared to traditional robotic counting techniques, which may be more complex and costly.

[0098] In embodiments, there may also be environmental benefits by reducing waste through precise dispensing, ensuring that only the required quantity of objects is used. The small size and low-cost enables the device to be deployed in edge cases, thereby eliminating required packaging such as compliance packaging for medication.

[0099] Also disclosed is a system for dispensing objects comprising an object dispensing container, the object dispensing container comprising a body defining an internal volume for storing objects; an outlet for dispensing objects from the body; a chute for moving the objects from the internal volume to the outlet; a frame for supporting the body during use; wherein when objects are required to be dispensed the operator causes the body to tip, while mounted in the frame from a stored position to a dispensing position, wherein in the dispensing position, the chute of the body is inclined so that one or more objects slide from the internal volume of the body, down the chute and are dispensed at the outlet, and following dispensing, the body tips back to the stored position.

[0117] Detailed Description of Embodiments of the Invention

[0118] Figure 1 depicts a container 10, constructed from materials such as PE or PP or other suitable materials. Secured to a structural frame 11 , the containers 10 primary function is to release objects (not shown) from a bulk stored within the container body 10.

[0119] The container 10 shown is cylindrical. The container 10 is enclosed by lid 17. The container 10 has an outlet 18 that is sized and shaped to allow for objects to be dispensed from the container body 10. The outlet 18 is at the end of a chute 20 in the container body.

[0120] The chute 20 is designed with the aim of facilitating the controlled movement, separation, and dispensing of the objects from the container 10 to the outlet 18. A plurality of the objects can move along the chute 20 with the intention that the objects are dispenses one by one at the outlet 18.

[0121] In the embodiment shown in e.g. Figure 6, the chute 20 has a predominantly V- shaped cross-sectional profile, which has been found to be highly effective in aiding unobstructed flow and separation of objects. The chute 20 aims to serve multiple functions: it allows a limited number of objects from the container 10 to be processed, facilitates their separation as they progress towards the exit point 18, and helps to ensure accurate counting as the objects are dispensed from the system. The chute 20 is characterised by a length having a longitudinal axis, with an entrance point 21 at the lower end for receiving objects from the container 10 and an exit point at the outlet 18 for dispensing the objects.

[0122] At the lowest part of the chute located at the bottom wall of the container, an opening 21 (or internal chute entrance 21 ) is provided to allow objects to enter the chute from the container's 10 internal volume. This opening 21 may be open on multiple sides as shown in Figure 8. Alternative, the opening 21 may be on a single side as shown in the embodiment of Figure 11 . For optimal compactness and efficiency, it has been found advantageous to locate the chute 20 adjacent to one side of the container 10 as shown in Figure 11 , allowing objects to enter the internal chute entrance 21 through the side of the chute 20.

[0123] The chute's 20 area-based entrance 21 naturally regulates the number of objects entering, maintaining a consistent volume that facilitates separation. It is thought to be important to avoid sharp edges and corners at the internal chute entrance as shown in Figure 12, as these can impede the natural flow of objects into the chute.

[0124] Once inside the internal chute entrance 21 , the area where the objects are located may be referred to as the chute storage area 40. This area serves as a temporary holding space for objects ready for dispensing. The chute storage area 40 can be designed to be wider than the main chute 20 by incorporating a funnel-shaped expansion that channels objects back into the narrower chute pathway (see cut away example in Figure 13A and Figure 13B). The walls 42 of the chute storage area 40 must be of sufficient height to prevent objects from escaping back into the main storage area of the container 10.

[0125] In the stored position (Figure 1), where the chute 20 and container 10 are oriented vertically with respect to their longitudinal axes, objects within the container 10 may flow naturally through the internal chute entrance 21 into the chute storage area 40. For larger objects, or when the chute requires additional filling, the container and chute may be tipped slightly backward and agitated to facilitate loading into the chute storage area 40. This agitation may assist in overcoming any static friction or interlocking tendencies of larger objects.

[0126] The chute storage area 40 incorporates a curved wall as seen in Figure 12 and 13A and 13B at the base of the chute 20 pointing towards the entrance 21. The curve towards the internal chute entrance 21 pushes the objects from the body of the container 10 towards the entrance 21 making sure they experience more resistance from entering. This design helps to ensure that the chute storage area 40 cannot become overfilled, which could compromise dispensing accuracy and increase the risk of jamming. Once there are objects in the chute storage area 40, the container 10 and chute assembly 20 are tipped downward into the dispensing position (Figure 2). In this orientation, the objects in the main storage area 40 of the container shift away from the chute entrance 21 due to gravity, preventing additional objects from entering the chute during the dispensing cycle. This isolation ensures that only the objects already within the chute assembly 20 are processed during the separation and counting steps, enhancing accuracy and reliability.

[0127] As the container is tipped and gravity acts upon the objects within the chute storage area 40, the objects begin to move towards the outlet 18. The objects can slide down the chute 20 to the outlet 18. A plurality of objects are moved along the chute 20 for dispensing.

[0128] Vibration can be applied by actuator 30 to the chute. Vibrational motion is typically initiated to aid in breaking up any clusters of objects and promoting individual movement.

[0129] This vibrational assistance can commence when the chute 20 reaches an angle of approximately 90 degrees from vertical. From this point, the container 10 may continue to tip further, but at a slower rate, to allow the objects to receive increased gravitational force while maintaining controlled movement towards the outlet 18.

[0130] When the vibration or shaking is generated by the main tipping actuator 12, there will be a "low vibration zone" within the chute 20. As objects travel down the chute, they pass through a point closest to the axis of the tipping motion, where the vibrational force exerted on the objects is significantly reduced compared to areas further from the tipping axis. Since vibrational force is critical for breaking up clusters of objects and ensuring individual separation, it has been found beneficial to position the pivot point of the tipping motion slightly above the midpoint of the container. This adjustment shifts the low vibration zone toward the exit point / outlet 18 of the chute 20, where the objects are already more separated, thus enhancing the overall effectiveness of the vibration mechanism.

[0131] As the objects progress along the chute 20, they enter a "separation zone" 44 of the chute 20. This zone 44 can comprise a shaped cross-section such as a V- shaped cross-section, which can be effective in separating individual objects.

[0132] At the conclusion of the separation zone, prior to the outlet there is an exit zone 46. The exit zone 46 is a steeper section of the chute 20 that may accelerate the objects prior to their departure from the chute.

[0133] The frame 11 is designed to support the container 10 or multiple containers 10 (Figure 9 and 10), suspending it / them above the surroundings and allowing for controlled tipping motion relative to the frame 10. This configuration enables the container or containers to transition between various positions necessary for the dispensing operation. An actuator 12, which may be housed either inside or outside the container / containers, provides the requisite tipping motion. The actuator can be an electric servo motor 12 that facilitates the motion of the container 10. The inclusion of the motor 12 within the container optimises the compactness. A shaft 13 from the motor protrudes externally, passing through a sealed aperture to connect to a servo horn 14 affixed externally. An auxiliary shaft 15 on the opposing side provides balance and additional support.

[0134] In an embodiment, the range of motion required during tipping is about 180 degrees. The container's vertical orientation comprises the storage position (Figure 1 ). An inclination of about 10, 20 or 30 degrees backward from vertical can represent a chute loading position.

[0135] During operation, the container or containers tip forward until the chute reaches an approximately horizontal (flat) position, initiating the dispensing sequence. Subsequently, the container continues to tip to the dispensing position in which the chute is at a steeper angle (Figure 2 and 3), approximately an additional 15, 20 or 25 degrees past horizontal. Once objects have been dispensed, the dispensing cycle is complete.

[0136] For object replenishment, the container 10 can have a removable screw-top lid 17 as shown in e.g. Figure 1 , though other mechanisms like a flap could be adopted. An exit point 18 atop the lid facilitates object egress. The inclusion of a gravity- actuated flap 19 prevents environmental contaminants, closing post-dispensing.

[0137] To ensure the integrity of the dispenser against external elements, particularly to prevent moisture ingress and contamination, the container may comprise a selfsealing lid mechanism 17 (Figure 14). This lid 17 can be activated through various means, including electromechanical actuation, gravity, the inherent motion of the container or a combination thereof.

[0138] Actuators, responsible for sealing mechanisms, are typically of a smaller scale compared to those used for the primary tipping movement. Their compact size allows for integration without significantly increasing the device's overall dimensions or power consumption. Employing a powered sealing method can enhance sealing integrity by exerting additional force on the sealing surfaces, thereby improving the effectiveness of the seal. This method, although requiring further powered components, provides greater control over the sealing process and ensures consistent performance across varying operational conditions.

[0139] An embodiment of a gravity-based self-sealing lid 17 involves the use of a rotating paddle 50 equipped with a counterweight 52 as shown in Figure 14. The paddle 50 is configured to move between the container lid 17 and the chute 20 when the container 10 is tipped backward into the storage position, thereby blocking the outlet of the chute 20. In this configuration, the stored position of the device is slightly inclined backward from the vertical to utilise gravitational force acting on the counterweight, which maintains the paddle 50 in the sealing position. When the container 10 is returned to the vertical orientation, the weight of the counterbalance 52 exerts force on the paddle 50, pressing it against the lid opening 17 and enhancing the seal. This gravity-driven self-sealing lid is particularly advantageous in systems comprising a single chute and container, as it obviates the need for additional motors or actuators dedicated to sealing functions.

[0140] An alternative embodiment employs an electromechanical seal, which may consist of a rotating paddle 50 arrangement or a paddle 50 connected to a solenoid or other actuator. Figure 15 shows actuated lids 17 with servo or solenoids which shut off the flow of the objects in a unit having four chute 20 / containers 10 in the same body. Using a powered sealing method is especially beneficial in configurations where multiple chutes 20 and containers 10 are attached to a single tipping motor. In such cases, the powered sealing mechanism can selectively shut off the flow from individual chutes 20 while allowing others to continue dispensing.

[0141] At the exit 18 of the container 10, a detection system comprising one or more sensors, one or more cameras or a combination thereof, can be employed to accurately quantify the dispensed objects. For precise dispensing, an LED 22 and phototransistor 23 are paired above and below the chute 20 respectively, establishing an object detection mechanism at the exit point 18. Dispense initiation causes the motor 12 to tilt the container 10, with the LED 22 and vibration motor 30 activating concurrently. This dual-action persists until reaching the set count or other operational constraints.

[0142] The device may further incorporate additional sensors and / or cameras to monitor the quantity of items remaining within the container. This information can be used to initiate restocking processes or alert the user when restocking is required.

[0143] Upon dispensing, the objects can be directed to a tray 27. Objects 26 flow systematically onto a designated receiving tray 27, designed for user collection. The tray 27 can be positioned slightly below the outlet 18 of the chute 20, at a distance sufficient to prevent interference with the tipping motion of the container 10. The tray 27 serves as a receptacle for the dispensed objects. To prevent the objects from bouncing out upon impact, the receiving surface of the tray 27 can include walls or barriers (refer to Figure 11 ).

[0144] Figure 16A, 16B and 16B show an alternative embodiment of the container. In this embodiment, a storage container S is associated with the container 10 and allows additional objects to be stored therein. In this embodiment, the larger storage container S remains stationary while the smaller associated container 10 and chute 20, mounted externally, tips independently. Figure 16A shows the stored position, and Figure 16C shows the dispensing position. Figure 16Bis a cut away showing the internals of the apparatus. The functionality remains substantially similar, with the chute 20 receiving objects through an aperture in the container S rather than being enclosed within it. As the chute 20 tips, it naturally seals against the exterior of the container S, maintaining the integrity of the storage environment.

[0145] Central to operation is a microprocessor. Users interact through a digital display screen 24 and input buttons 25, providing control over dispensing specifications. User scheduling and advanced options are available through a wireless digital interface.

[0146] The device can be designed with the capability to interface with external systems, including inventory management systems, electronic medical records (EMR), and automated packaging equipment. This integration enables seamless communication and data exchange, facilitating functionalities such as automated inventory tracking, prescription verification, dispensing history logging, and compliance monitoring. Data from these verification processes can be communicated to the control system, which can take corrective actions if necessary, such as initiating an alert, rejecting the batch, or adjusting future dispensing operations.

[0147] The central control system maintains real-time tracking of the dispensed object count against a predefined target quantity. Upon reaching the requisite count, the control system can halt the dispensing protocol by promptly initiating the tipping back of the container 10 to the stored position. The return tipping action can be rapid to prevent additional objects from being dispensed beyond the target count. In applications using servo motors 12, the required speed for tipping back can be readily achieved.

[0148] It will of course be realized that while the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is herein set forth.
