DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Referring now to the drawings and the illustrative embodiments depicted therein, a contactless order dispensing system 10 for dispensing e-commerce orders to customers 12 without the need for interaction between the customer and a human associate (FIG. 1). The dispensing system 10 includes a customer order pick-up or access portal 14 at which an order is presented to the customer 12 for retrieval. The dispensing system 10 is particularly beneficial for e-commerce micro-fulfillment operations (i.e. localized or small scale order fulfilment facilities), such as may be provided in a receiving portion or other non-customer accessible portion of a grocery store 11, department store, or retail store, to allow customers to retrieve their order from the exterior of the store without having a face-to-face or in-person interaction with another human (FIGS. 1 and 4). The dispensing system 10 allows the customer 12 to enter instructions to indicate that they are present and ready to retrieve their order. In addition to other benefits, this arrangement is particularly beneficial in limiting the spread of germs and disease, such as in times of public health emergencies, increased efficiency of space usage within order fulfillment facilities, and decreased customer wait times when retrieving their orders. The dispensing system 10 includes a transportation system, such as a conveyor system 16, in communication with the access portal 14 to transport the customer order to the access portal 14 (FIGS. 2-3) A storage buffer 18 is provided to store prepared customer orders until the customer 12 requests the order at the access portal 14 (FIG. 4). The dispensing system 10 is controlled by an order management system having a computer. The dispensing system 10 may include a confirmation system in communication with the order management system to verify that the customer 12 has retrieved all of the order contents from the access portal 14.

[0024] Referring to the illustrative embodiment of FIGS. 1-4, the contactless order dispensing system 10 includes multiple customer order pick-up/access portals 14 that are spaced apart from one another and accessible from an exterior 20 of the store 11. Each access portal 14 includes an exterior access door, shown in the form of an overhead roll-up type access door 22, and a customer/user interface or system 24 (FIG. 1). Upon arrival at the store and access portal 14, the customer 12 inputs unique customer information and/or order identifying information or credentials, such as an access code or pin number, into the user interface 24. For example, the user interface 24 may include a customer input device, such as an analog keypad or a touchscreen. Upon verification of the customer and order identifying information, the access door 22 opens to provide the customer access to an order dispenser 26. The order dispenser 26 may include a safety door that remains closed until the order contents have arrived at the access portal 14 such that the order contents are safely positioned, which may reduce or eliminate the possibility of injury to the customer 12 from interaction with the access portal components. A shroud 27 is provided around the order dispenser 26 to impede or prohibit the customer from accidently (or intentionally) inserting body parts into the order dispenser. Preferably, the opening in the shroud 27 is smaller in dimension than the dimensions of a transport receptacle in which the order is presented to the customer. As such, the customer is prohibited from removing the transport receptacle from the order dispenser 26. While it may be preferable that customer orders are transported and presented to the customer in a receptacle or tote 40, it is contemplated that some items and/or portions of a customer's order may be transported directly on the conveyor system 16 and presented to the customer 12 without a receptacle. Optionally, a proximity or motion sensor may be provided to open the access door 22 automatically when a customer arrives at the access portal 14. The access door 22 and/or order dispenser safety door may include an automatic reversal system, optical sensor, light-curtain, pressure sensor, or similar safety device, which, in the event that an object or customer is beneath the respective door, will automatically reverse the door if it has begun to close.

[0025] The access portal 14 includes a customer confirmation system, in the form of mechanical buttons 28, to allow the customer to confirm that they have completed retrieving their order or to indicate an issue with their order, such as indicating that an order item is damaged or is no longer wanted. While the confirmation system is illustrated as mechanical buttons 28 in FIGS. 1 and 3, it will be appreciated that a touchless sensor (e.g. an optical sensor) may be utilized to transmit image data to the order management system. The order management system utilizes the image data to confirm whether the customer has completed the retrieval of their entire order. In this manner, the touchless sensor and order management system cooperate to reduce contact points the customer must touch. The user interface 24 may include a scanner system to provide touchless input of the unique customer and order info, which may further reduce contact points that the customer must physically interact with or touch. The scanner system may be configured to scan and identification card or may be a biometric scanner. Further, an order dispenser monitoring system may be provided to confirm whether the order contents have arrived at or have been retrieved from the order dispenser 26. An exemplary order dispenser monitoring system is discussed in more detail below.

[0026] Referring to FIGS. 2 and 3, the transportation system of the dispensing system 10 is formed by a conveyor system 16 that includes a sortation system or sorter 30, an input conveyor 32, a transfer conveyor 34, a discharge conveyor 36, and a return conveyor 38. The conveyor system 16 typically transports receptacles, bins, or totes 40, which contain customer orders or portions of customer orders, to and from the access portal 14, however, it will be appreciated that orders and individual items may be transported along the conveyor system 16 without totes. The sorter 30 includes multiple roller conveyor segments 42 and right-angle-transfers (RATs) 44 adjacent to each of the input conveyors 32 for each access portal 14. The RAT 44 diverts order totes 40 from the sorter 30 to the adjacent input conveyor 32 of a particular access portal 14 that requires the order. The sorter 30 may include motor driven rollers and/or a motorized belt conveyor to move totes along the sorter 30 toward the various access portals 14. As best shown in FIG. 2, the input conveyor 32 is a segmented conveyor that functions as an accumulator to accumulate multiple order totes 40 along the input conveyor 32 in sequence until they are moved to the access portal 14. The segments of the input conveyor 32 may be independently controlled segmented belt-on-roller (SBOR) conveyors 32a, or any other suitable accumulator conveyor system.

[0027] The transfer conveyor 34 is positioned between the input conveyor 32, the access portal 14, and the discharge conveyor 36 (FIG. 2). The transfer conveyor 34 includes a pair of right-angle-transfers (RATs) 46a and 46b, with the first RAT 46a positioned at the downstream end of the input conveyor 32 and adjacent to the second RAT 46b which is positioned between the order dispenser 26 and the discharge conveyor 36. The first RAT 46a functions to receive totes 40 from the input conveyor 32 and buffer that tote while it waits to move onto the second RAT 46b. The second RAT 46b performs multiple functions including receiving the next order tote 40 from the first RAT 46a, transferring that tote 40 into the order dispenser 26 (which later returns the tote 40 to the second RAT 46b after the customer has completed order retrieval), and transferring the completed tote 40 from the order dispenser 26 to the discharge conveyor 36. The discharge conveyor 36 transfers completed order totes 40 to the return conveyor 38 (FIGS. 2 and 3). The return conveyor 38 may include motor driven rollers and/or a motorized belt conveyor 45 (FIG. 2) to move completed totes along the return conveyor 38 to return the completed totes to the order fulfilment pick system 48 or the storage buffer 18 as directed by the order management system. The order dispenser 26 includes a single motorized roller or belt conveyor section and an indexing system that receives the tote 40 from the second RAT 46b. The indexing system positions the tote 40 in an ergonomic pick-up position (e.g. angled at 15° down) to allow the customer to retrieve their order without removing or manipulating the tote 40. The order dispenser 26 also includes a locking device to retain the tote inside the order dispenser 26 so that the customer 12 cannot remove the tote 40.

[0028] A confirmation system may be provided to inspect the tote 40 to confirm that it is empty, or if the customer has indicated that they are rejecting an item (such as by entering an input at the user interface 24), that the tote contains something. The confirmation sensor may utilize various sensors or scanners, such as ultrasound, optical sensors, label scanners, etc. to inspect the tote that is present in the order dispenser 26. Optical sensors may create a two-dimensional or three-dimensional point map of the tote 40 and/or items present in the tote 40 to confirm whether the tote is empty or not. If the customer indicates that they are rejecting an item and if the confirmation system senses that an item is present in the tote, the order management system may assume that the present item is the item that the customer has indicated that they are rejecting. Optionally, the confirmation system may include a scanner, such as a barcode scanner or the like, to identify the particular item that is present in the tote. The order management system may confirm that the item, which the customer rejected, matches the item that is present in the tote. The order management system confirms that the tote status matches the expected status before proceeding. For example, the tote status and expected status match if the customer has indicated that they have completed picking up their order without indicating a rejected item and the confirmation sensor confirms that the tote is empty. For another example, the tote status and expected status match if the customer has indicated that they have completed retrieving their order and have rejected an item and the confirmation sensor confirms that something is present in the tote. If the tote and expected statuses match, a light curtain or similar sensor will activate above or otherwise proximate the order dispenser 26 to determine if the safety door is clear. If the safety door is clear, it will close automatically. Subsequent order totes for the customer's order index into the pickup position at the order dispenser 26 and the cycle repeats until the customer has picked up the entirety of their order. The dispensing system 10 may include a customer alert device to notify the customer if they have left an item in the access portal 14 by mistake.

[0029] For example, totes 40 index forward through the accumulation positions on the input conveyor 32 until they reach the first RAT 46a. The first tote to arrive at the first RAT 46a is immediately diverted sideways onto the second RAT 46b which immediately diverts the tote onto the single motorized roller or belt section. The indexing system indexes the tote in the pick-up position and the locking device retains the tote in the order dispenser. Once the tote 40 is in position in the order dispenser 26, the order dispenser safety door opens automatically to allow the customer to retrieve their order items from the tote 40. Once the customer indicates that they have completed retrieval of their order (by pressing one of the buttons 28, see FIGS. 1 and 3). At this point, the confirmation system inspects the tote 40 to confirm that it is empty or that an item is present if the customer has indicated that they are rejecting an item. Once the tote status matches the expected status, the light curtain activates above the tote opening, and if clear, the safety door will close automatically. Then the locking device releases the tote 40 and the single motorized roller or belt section transfers the completed tote 40 out of the order dispenser 26 onto the second RAT 46b. The second RAT 46b then transfers the completed tote 40 onto the discharge conveyor 36 and then immediately receives the next order tote 40 from the first RAT 46a. Subsequent order totes for the customer's order index into the pickup position and the cycle repeats until the customer has picked up the entirety of their order.

[0030] The input conveyors 32 and discharge conveyors 36 may be inclined, declined or level such that the conveyor system 16 can be positioned at various heights to meet the access portal 14. Likewise, the access portal 14 may be configured at different heights as necessary to meet customer requirements and preferences, such as at wheelchair accessible heights as determined by the American with Disabilities Act (ADA) requirements, standing height, or vehicle trunk height, etc. While the transportation system of the illustrated embodiment of FIGS. 2-4 is shown as a conveyor system 16, it is contemplated that an autonomous robotic vehicle or automated mobile robot (AMR) may transport the orders from the storage buffer 18 to the access portal 14. It is also contemplated that a conveyor system and one or more AMRs may be utilized to transport orders and totes between the storage buffer 18 and the access portal 14.

[0031] The sorter 30 and return conveyor 38 are connected with and in transport communication with an automated storage buffer 18, in the form of an automated storage and retrieval system (ASRS), that stores picked or completed customer orders until the customer arrives to retrieve their order. In order to provide fast service to customers 12 as they arrive at the store, the pick system 48 in the store begins picking the order, typically, as soon as the customer submits their order. The pick system 48 includes one or more order picking workstations 49, such as goods-to-person (GTP) workstations or goods-to-robot (GTR) workstations, at which operators pick order items into totes 40. Once the pick system 48 has picked the full order, the order tote 40 (or multiple totes for large orders or for orders containing different types of items, which will be discussed in further detail below) is transported to the storage buffer 18. The order management system controls the storage buffer 18 to position the filled order totes 40 inside the storage buffer 18 and to release order totes 40 to the access portal 14 once the customer 12 has arrived and instructed the dispensing system 10 that they are ready to retrieve their order.

[0032] Due to the nature of goods that a customer typically orders from a grocery store, it may be necessary to provide multiple temperature zones within the storage buffer 18 to maintain freshness and quality of the order items during the time between the customer placing the order and the customer retrieving the order. As illustrated in FIG. 4, the storage buffer 18 includes multiple temperature zones, with ASRS storage racks 50 located in each of the temperature zones. The exemplary temperature zones illustrated in FIG. 4 include an ambient temperature zone 52 for room temperature or similar items, a chilled temperature zone 54 for cooled or chilled items (i.e. at a lower temperature than the ambient zone 52), and a frozen temperature zone 56 for frozen items (i.e. at or below freezing temperature and at a lower temperature than the chilled zone 54). Fewer or additional temperature zones may be provided as desired to provide adequate temperature control for customer orders. If a customer order contains items that require different temperature zones, the order management system divides the order into multiple totes 40, which are each transported to and stored in the appropriate temperature zone. When the customer arrives and instructs the dispensing system 10 to retrieve their order, the order management system releases each of the totes for that order from the storage buffer 18, including from the different temperature zones. Preferably, all of the totes 40 for that order arrive at the access portal 14 in sequence so that the customer 12 receives all of their order in one consecutive stream of totes 40.

[0033] While the ASRS racks 50 of storage buffer 18 are described above and illustrated in FIG. 4 as being dedicated to a single temperature zone, it is contemplated that single storage rack 50 may be include two or more temperature zones within the rack which are maintained at two of more different temperatures. For example, the storage buffer may include an ASRS having a single storage rack that includes a group of levels maintained at a chilled temperature and another group of levels at a frozen storage temperature, such as described and illustrated in commonly owned and assigned U.S. Pat. No. 11,067,329, issued Jul. 20, 2021. Alternatively, instead of an ASRS storage buffer as illustrated in FIG. 4, it will be appreciated that the buffer may be a manual storage and retrieval system that is manually operated by human operators such that the human operator manually places orders into storage and retrieves the orders when the customer has arrived and is ready to pick-up their order. The human operator may transport the order, in a tote 40 for example, to the access portal 14 where it is presented to the customer at the order dispenser 26.

[0034] Preferably, the time required to release the customer order from the storage buffer 18, transport the order to the access portal 14, and ultimately present the order to the customer at the order dispenser 26 is less than ten (10) minutes, and more preferably less than five (5) minutes, and most preferably less than two (2) minutes.

[0035] As illustrated in FIG. 4, the dispensing system 10 may be adapted to dispense larger orders, such as for large volume orders for caterers, restaurants, or the like. The dispensing system may include a large order retrieval bay or space 58 that contains large order containers 60 (e.g. gaylords, pallets, etc.) and an operator or an automated mobile robot (AMR) transfers order items from a sorter extension 62 that is connected to the sorter 30 and places them into a large or container. When the customer arrives for their large volume order, the large order containers 60 can then be loaded onto a vehicle. AMRs may be used to load the large order containers 60 onto the vehicle to reduce or eliminate close contact between a store associate and the customer or vehicle driver.

[0036] Referring to the illustrative embodiment of FIG. 5, a method 100 is provided for contactless dispensing of an order to a customer. Method 100 includes receiving 102 an order from a customer via the internet or other channel. The order data is stored in an order management system that includes a computer. The order 104 is prepared or filled in an order fulfilment pick system 48, which is onsite at a store location, such as a grocery store 11, department store, convenience store, or the like. After the order is filled, it is stored or buffered 106 in a storage buffer 18 until the customer 12 arrives to pick-up the order. When the customer arrives, the customer enters 108 identification information, such as an access code, into a user input device of a customer/user interface or system 24 to request their order. The order management system confirms 110 the customer identification info and instructs the storage buffer 18 to release 112 the customer's order. The method then includes transporting 114 the order from the storage buffer 18 with a transportation system, such as a conveyor system 16, to a customer order pick-up access portal 14. The access portal 14 receives and dispenses 116 the order to the customer in a manner such that the customer 12 does not have direct contact with a store associate or other human. The customer retrieves 118 the order and the order management system confirms 120, with a confirmation system including a confirmation sensor, that the customer has completed retrieval of their order.

[0037] Buffering 106 the order in a storage buffer 18 may include separating portions of the customer order and storing each portion in different temperature zones of the storage buffer as required for the different items in the order (e.g. ambient temperature zone 52, chilled temperature zone 54, and frozen temperature zone 56). The storage buffer 18 includes an automated storage and retrieval system store and buffer the order after it is filled in the pick system 48. Confirming 120 that the customer has retrieved their entire order is performed by an order management system that includes a computer and a confirmation system or sensor located proximate the access portal 14.

[0038] Dispensing 116 the order to the customer includes opening an order dispenser safety door between the customer 12 and the conveyor system 16 and presenting the order to the customer at the order dispenser 26 opening defined by the open safety door. The method 100 may notify the customer with an alert device, such as an audible signal or a light, that an order item is present at the access portal 14 and ready for retrieval. For example, the alert device may illuminate in the event that an item is left in a tote at the access portal 14 for an extended period of time without an indication from the customer that they are rejecting that item. The method 100 may also include receiving an instruction from the customer that they are rejecting at least one order item and the method 100 confirming that the rejected item is present at the access portal 14. The method 100 may utilize a scanner, camera, or ultrasound sensor to determine that the rejected item (or any item) is present at the access portal 14.

[0039] Preferably releasing 112 the order and transporting 114 the order from the storage buffer 18, receiving and dispensing 116 the order at the access portal 14 and dispensing the order to the customer are all performed in ten (10) minutes or less, and more preferably in five (5) minutes or less, and most preferably in two (2) minutes or less.

[0040] Thus, the present invention provides a contactless order dispensing system and method for dispensing an e-commerce order to a customer without the customer interacting with a human associate. The dispensing system includes a customer access portal, a storage buffer, and a transportation system to transport orders from the storage buffer to the access portal. The storage buffer receives filled orders from an order fulfillment facility that is on-site at the store location and releases the stored customer order when the customer has arrived at the store. The storage buffer includes multiple temperature zones to store portions of the customer order at different required temperatures. The customer access portal presents the order (or portions of the order) to the customer an exterior of the store location. The dispensing system includes a confirmation sensor system at the access portal to verify whether a customer has retrieved their entire order or whether the customer has rejected one or more of the order items and left the rejected item(s) in the tote. The dispensing system is capable of providing the order to the customer within about two minutes of the customer arriving at the access portal.

[0041] Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the present invention which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
