Cross Reference to Related Applications

[0001 ] This application claims priority to and the benefit of US Provisional Patent Application Serial No. 63/307651, entitled "2- STAGE PADDLE ROTOR AND AUGER FEED WEIGHING SYSTEM", filed on February 08, 2022, the disclosure of which is incorporated herein by reference in its entirety.

Background

[0002] The embodiments described herein relate to bulk product dispensing, and in particular, to automated bulk food dispensing.

[0003] Bulk food purchasing is common in retail and grocery shops. Currently bulk food purchasing in stores is manual. A consumer scoops, weighs, tags, and identifies their bulk food products using plastic or paper tags and weigh scales in the stores to determine the price that is to be paid for the consumer's food selection. In some cases, the consumer may not weigh the bulk product until reaching the cash register, or they may not know how much product they need by weight since the recipe they want to make may express the amount of ingredients required in another format such as cups, fluid ounces or litres.

[0004] This process leads to inaccurate and inefficient weighing methods and to consumers purchasing too much or too little product for their needs. This can lead to wastage or requiring additional trips for more ingredients. The current purchasing system for bulk products can lead to errors caused by the user, and inventory control may be compromised for the retailer. The current process can be time consuming and inaccurate as each step of the process is manually performed by the user. The current process can also be wasteful and may lead to cross contamination of food due to bacteria, consumers misplacing the scoops, consumers attempting to return product to the bins and due to product spilling out of the bags while manually filling with the scoop. An opportunity for fraud, intentional or unintentional, is present if a consumer mislabels a similar looking product. In addition, the consumer does not have any instant information about cost or quantity of the bulk food product they are purchasing. The current purchasing systems for bulk products leave the consumer with unknown quantities of the product until they reach the cash register, which means they may over or under spend unknowingly.

[0005] The current open-bin system used in most bulk food stores exposes product to the air resulting in loss of product freshness, oxidization of food product, loss of flavour and absorption of flavours and smells from other store products. While airtight lids could be added to the bins, the size of the bin and the need for consumers to physically reach their hands inside the bin with a scoop, will still result in high levels of contamination and air exchange and provides opportunity for the consumer to fail to re-seal the lid when they are done. A significant additional hazard is present with open or lidded systems whereby germs, contaminants or pathogens from a consumer can be deposited on the product through breathing or sneezing.

[0006] If the consumer changes their mind about purchasing the product, they may leave the bag of product somewhere else in the store, this inventory cannot be tracked to the person, nor can the inventory be returned to the bin. Therefore, this product must be wasted, and the cost of the product written off by the retailer or manufacturer. Manual filling of the bins by retailers can lead to spillage and poor estimating of bulk volume which in turn results in inaccuracies in-purchase and store room levels which can be costly to the retailer. Over or understocking can be a problem without immediate information related to quantities purchased, time of purchase and the lack of information available to measure total quantity and cost of waste.

[0007] An initial design for a 1 stage system consisting of a cartridge / container with built in auger feed system is disclosed in US utility patent US 16/912989 filed on Dec 13, 2021, entitled "Automated Bulk Product Dispenser" which is incorporated by reference in its entirety. According to this disclosure, the full cartridge and auger weighs roughly 30kg and is mounted on loadcell to provide active weight feedback. It was determined since the system is used to sell product based on weight a certification from Measurements Canada must be acquired. The standards for Measurements Canada required an accuracy of lg for this classification of products with a maximum reading ratio 3000:1. This translates to a maximum allowable scale reading of 3 Kg, which is beyond the initial design constraints of the first system.

[0008] There is a desire to implement an improved bulk food dispensing system and method that provides for active product weight measurement and inventory information to adhere to appropriate standards. Specifically, there is a desire for maximum scale reading of 3 Kg.

Summary

[0009] A system and method for a feed weighing system used for automated bulk product dispensing.

The system comprises an airtight cartridge that utilizes a rotational motorized paddle valve to control the flow of product into a secondary paddle feed weighing stage. Using a digital interface or a dispense button, consumers select a specified amount of bulk product to be dispensed (by weight, mass, volume, or cost). The product is then dispensed into a receptacle container and the system calculates the quantity and corresponding cost that was dispensed into the receptacle container. In alternate embodiment, instead of pre-selecting a quantity of product, the user may hold the button down until the system indicates that the desired quantity of product has been dispensed. This quantity may be pre-set to a specific desired quantity, or the user may release the button once a visual display indicates that the desired quantity has been reached. Using a personal identification key system, consumers can activate the automatic dispensing system. The identification key may be used to track and store the user's dispensed bulk products during a shopping session. This information may be uploaded to a database that is later called upon at the time of checkout to tabulate the user's total cost of dispensed bulk products. The system can also update an inventory database of the bulk products.

[0077] FIG. 25 is a state diagram illustrating dispensing activity of the system. According to FIG. 25, the system 2500 initiates with a Power On event at step 2502 at the Run state at step 2504. The system then determines whether the pods (or modules) are configured at step 2506. If it is configured, then the system determines whether a ping timer has expired at step 2508. If the pods are not configured, then the system moves to a Configuration state at step 2510 which then loops back to the Run state at step 2504.

[0078] According to FIG. 25, If the ping timer has expired at step 2512, the system will move to the Ping state 2514 and then loops back to the Run state at step 2504. However, if the latter is true (i.e., ping timer not expired) at step 2516, the system then further checks whether the message queue contains a message at step 2518. If the answer is Yes here (i.e., message queue contains a message), the system moves to the Process Message state at step 2520 which will execute the events of AddToCart and PodConfigData Request.

[0079] According to FIG. 25, if the answer is No (i.e., message queue does not contain a message) at step 2518, the system will return to the Run state for further processing at step 2504. Thereafter, a further state of Process Communication is executed as a parallel thread 2522.

[0080] FIG. 26 is a state diagram illustrating dispensing Teensy micro-controller activity of the system. According to FIG. 26, the system 2600 initiates with a Power On event at step 2602 where it proceeds to a Run state at step 2604. The Runs state checks whether the system is configured at step 2606. If it is not configured, the system then moves to the Configuration state at step 2608 and then loops back to the Run state at step 2604.

[0081 ] If the system is configured at step 2606, the system checks whether the system is online at step 2610. If the system is online at step 2610, it then proceeds to the Online state at step 2612 and then to the Dispensing state at step 2614. If the system is offline, it moves to the Offline state at step 2616, then jumps to the Dispensing state at step 2614.

[0082] According to FIG. 26, the system checks whether there is a message to process at the Dispensing state at step 2618. If there is a message to proceed, the system moves to the Process Message state at step 2620. The Process Message state at step 2620 contains functions to check for "Go Offline Messages", "Go Online Messages", "AddToCart Success" and "PodConfigData".

[0083] According to FIG. 26, the system loops back to the Run state at step 2604. Furthermore, if the message to proceed is negative (e.g., No) at step 2618, the system also loops back to the Run state for further instructions at step 2604. [0084] According to FIG. 26, a further state of Process Communication is executed as a parallel thread at step 2622.

[0085] FIG. 27 is a flow chart illustrating communication steps of the system. According to FIG. 27, system 2700 initiates with Master Arduino at step 2702 where it moves onto the Pod List at step 2704 and then to For each Pod at step 2706. The system then checks to see if there any outgoing messages at step 2708. If Yes, the system proceeds to the step of I2C to Pod DataForPod at step 2710.

[0086] According to FIG. 27, the system then checks if it is successful at step 2712. If successful, then the system moves to the Next Pod at step 2714 and then to Restart Communication Loop at step 2716 where it returns to the PodList function at step 2704. If it is not successful (i.e., failed) at step 2712, the system then Requeues Message 2718, then moves to the Next Pod at step 2714.

[0087] According to FIG. 27, if the outgoing message is No at step 2708, the system then executes the command "I2C to Pod DatFromPod" at step 2720. The system then checks whether the "Response Length is greater than 0" at step T1 1. If Yes, it then accepts Pod response and add it to Message Queue at step 2724. Thereafter, it then proceeds to the Next Pod at step 2714, then the Restart Communication Loop at step 2716. Finally, all processes at the Restart Communication Loop step returns to the Pod List at step 2704 command for further processing.

[0088] FIG. 28 is a state diagram illustrating various motor configurations. According to FIG. 28, state diagram 2700 illustrates the different states of the motor configuration 2802 including speed 2804 (ranging from 0 - 255), oscillation mode 2806 (chosen from Boolean true or false), gyration mode 2808 (chosen from Boolean true or false) and portion control 2810 (chosen from Boolean true or false).

General Considerations

[00100] The functions described herein may be stored as one or more instructions on a processor- readable or computer-readable medium. The term "computer-readable medium" refers to any available medium that can be accessed by a computer or processor. By way of example, and not limitation, such a medium may comprise RAM, ROM, EEPROM, flash memory, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer. It should be noted that a computer-readable medium may be tangible and non-transitory. As used herein, the term "code" may refer to software, instructions, code or data that is/are executable by a computing device or processor. A "module" can be considered as a processor executing computer- readable code. [00101] A processor as described herein can be a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor can be a microprocessor, but in the alternative, the processor can be a controller, or microcontroller, combinations of the same, or the like. A processor can also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. Although described herein primarily with respect to digital technology, a processor may also include primarily analog components. For example, any of the signal processing algorithms described herein may be implemented in analog circuitry. In some embodiments, a processor can be a graphics processing unit (GPU). The parallel processing capabilities of GPUs can reduce the amount of time for training and using neural networks (and other machine learning models) compared to central processing units (CPUs). In some embodiments, a processor can be an ASIC including dedicated machine learning circuitry custom-build for one or both of model training and model inference.

[00102] The disclosed or illustrated tasks can be distributed across multiple processors or computing devices of a computer system, including computing devices that are geographically distributed. The methods disclosed herein comprise one or more steps or actions for achieving the described method. The method steps and/or actions may be interchanged with one another without departing from the scope of the claims. In other words, unless a specific order of steps or actions is required for proper operation of the method that is being described, the order and/or use of specific steps and/or actions may be modified without departing from the scope of the claims.

[00103] As used herein, the term "plurality" denotes two or more. For example, a plurality of components indicates two or more components. The term "determining" encompasses a wide variety of actions and, therefore, "determining" can include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like. Also, "determining" can include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like. Also, "determining" can include resolving, selecting, choosing, establishing and the like.

[00104] The phrase "based on" does not mean "based only on," unless expressly specified otherwise. In other words, the phrase "based on" describes both "based only on" and "based at least on." While the foregoing written description of the system enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The system should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the system. Thus, the present disclosure is not intended to be limited to the implementations shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
