FIG 1 discloses an embodiment of a system for automated item delivery. The system includes a delivery counter 2, a controller 7, a processor module 15, a memory unit 16, a first input unit 11, and a second input unit 14, which cooperates together to carry out a disinfected automated delivery of items.
The delivery counter 2 have an access from two sides, a staff window 3 accessible by staff of a restaurant and a customer window 4 placed opposite to the staff window and is accessible by customer of the restaurant. The delivery counter 2 has a static mounting frame for providing a support structure to mount all the sensors, mechanical and electronic subsystems.
The delivery counter 2 is provided with a linear actuation mechanism for sliding windows 3, 4. It functions for precise and smooth sliding of the windows 3, 4.
In one embodiment, the customer is not required to access the disinfection chamber 5 through the customer window 4 by entering his hand inside the chamber 5, rather, a retractable tray can be provided, which extends when the customer window 4 opens up, so as to hand over the item to the customer. Once the customer has picked up the order, the tray shall retract back. In such scenario, a linear actuation mechanism for the tray shall be provided, which functions for precise and smooth linear motion of the tray in and out of the customer window 4. The delivery counter 2 includes a disinfection chamber 5 for keeping an item before delivery to the customer, and a disinfection unit 6 coupled to the disinfection chamber 5. The disinfection unit 6 is functional to disinfect the item kept in the disinfection chamber 5.
The controller 7 controls functioning of opening of the staff window 3 and the customer window 4 to keep the staff window 3 and the customer window 4 locked during a disinfection period when disinfection chamber 5 is functioning to disinfect the item. The controller is a typical computing microcontroller which receives feedback regarding disinfection operation or functioning of the disinfection unit 6, and accordingly send a signal to the actuator of the staff window 3 or the customer window 4 for allowing opening of them, if the disinfection unit 6 is non-functioning. The controller 7 is also enabled to control disinfection unit 6 for disallowing or stopping its operation until either or both of the staff window 3 and the customer window 4 are closed.
The system also includes a sanitizer dispensing means 8 which dispenses a sanitizer, and a proximity sensor 10 placed in proximity to the sanitizer dispenser 8 and senses presence of hands in proximity to the sanitizer dispenser 8 and generates a use information 9. The controller 7 receives and processes the use information 9 and opens the customer window 4, if the hands were detected to be in proximity of the sanitizer dispensing means 8. The proximity sensor 10 is not kept activated, rather it is activated only once it is confirmed that the order is to be picked up by the customer. The system 1 includes a first input unit 11 which receives an order identification 12 related to identification of an order. The controller 7 controls receive and processes the order identification 12 and if the order identification 12 is correct, it activates the proximity sensor 10.
The controller 7 continuously listens the feedback from all the sensors, limit switches and executes the entire process flow accurately and safely. Also, the controller continuously reads limit switch and proximity sensor status and executes actuation of the motors of window door and food tray. The synchronization and execution of the entire process flow is carried out accurately and safely.
As shown in FIG. 2, there are multiple windows 3, 4 for enabling multiple order item deliveries. In such scenario, it is important to identify which item is placed in which window. To enable such identification, there are additional elements added to the system 1. The system 1 further includes a second input unit 14 which receives a customer window number data 15 related to a customer window in which the order is kept. This entry is made by a staff while placing the item in the appropriate disinfection chamber 5 through the staff window 3. The system also includes a processor module 15 which receives the order identification 12 and a customer window data number 15, and processes them up by linking them and to store the linked data the lookup table 13, which is stored in a memory unit 16.
In furtherance, when a customer enters an order identification 12 through the first input unit 11, the control unit 7 receives the order identification 12 and accesses the lookup table 13 to identify the customer window 4 related to the order identification 12 and opens the customer window 4 linked to the order identification 12, once the use of the sanitizer is confirmed. In one embodiment, the sanitizer means 8 may not be provided and accordingly, no such use information is required to control opening of the customer window 4.
The first input unit 11 can be a code identification reader or a signal receiver. The first input unit 11 is adapted to read a computer readable code or receive a signal to determine the order identification 12. In one implementation, the first input unit 11 is a QR code reader, and the order data is a QR code.
The delivery counter 2 may also have a user interface. It communicates to the user the current status of order and prompts the user to take actions. Also, makes the user experience more pleasant and relevant. Even though, the FIG 2 shows 3 windows placed on below another, in some implementation of the delivery system 1, there can be a matrix of windows 3, 4 which can be various possible combinations of rows and columns. Each of such windows can be used for placement and receiving of orders. In another implementation, there can be only one staff window 3, and a matrix of customer window 4. In such scenario, only one disinfection unit 6 can be enough. However, such implementation may make the system slower, as the access to customers may be limited due to disinfection operations for each order, as only one disinfection unit 6 is provided. Multiple customer windows 4 is also helpful when a customer has made multiple orders, or if the order is too big to be kept in one of the chambers 5, the order/s may be placed in multiple chambers 5 to be accessed by one customer at a particular time. The present disclosure is further explained through a user journey who is using the system of current invention in one implementation of the system. The journey is explained through various steps of the flow illustrated in FIG. 3. The steps involved are as follows:
• Initially user scans a restaurant QR code at the storefront using a smartphone camera. This redirects the user to the webpage/app. In an alternate embodiment, the user can place the order remotely through the app. In yet another embodiment, instead of the restaurant QR code scanning, any other mechanism can be used for opening the webpage or mobile application on the user device. Even GPS data captured through a mobile phone or any other mobile communication device of the user can be enough to open the relevant mobile application or web application related to a particular store at a particular location.
• User chooses the desired items and completes the payment. This payment can be made in cash, or through the Mobile App or Web App itself.
• Once the order is paced, the user is assigned an Order CRN. Users are notified of the live updates of the order status either through the mobile device, or a display screen which placed near to the delivery counter.
• User is notified when the food is ready. User is also provided with a delivery QR code, which can be scanned for effectuating the delivery of the item. This delivery QR code can either be generated at the time of generating the CRN or while the user is notified regarding notification of readying of the food for delivery. Instead of the delivery QR code, any machine-readable code can be generated, or the user can manually enter a code issued to him through the status notification via an input device associated with the delivery counter.
• The delivery QR code provided to the customer holds the information about Customer Name, Order CRN and Customer ID. When the delivery QR code is scanned at the scanner provided functionally coupled to the delivery counter, all this data is read by the scanner and Customer name and Order CRN is displayed on the screen.
• In the background, customer CRN and a window number of the delivery counter are communicated by the scanner to the central server. Server records the window number and displays the same against the corresponding order CRN on a Kitchen Delivery Screen (KDS) for the takeaway assistant.
• The takeaway assistant transfers the food order from grid to the corresponding window (through the back door) of the delivery counter as dictated by the KDS.
• Once the food is kept in the window UV disinfection cycle starts. If the back door is opened for any reason, the UV disinfection cycle stops and resets the time. This ensures complete safety and efficient disinfection.
• After the UV disinfection cycle is over, a message appears on the screen which prompts the user to move their hands below a sanitizer nozzle. Only when the user takes their hands close to the nozzle, liquid sanitizer is dispensed enough to sanitize both the hands.
• The door then slides open followed by outward movement of the tray for better accessibility.
• The user then collects the food order and puts it in the bag provided along with it. • Once the user moves away, the tray moves back in the window and the door closes. The home screen is displayed on the screen.
There are several advantages of this system such as accurate and hygienic delivery with less human interaction. Also, it helps in replicating best practices across existing modules and helps to render an overall compact unit.
