SYSTEM AND METHOD FOR PICKING AND DELIVERING ITEMS FOR AN ONLINE SUPERMARKET

Description

[0001] The present invention relates to a system and a method for picking and delivering items according to a multitude of customer orders. These orders comprise pocketable items from an online grocery retailer or online supermarket, such as fruits and vegetables, dairy products, meat and sausages, (frozen) refrigerated products, beverages, drugstore items, electronic products, and / or household goods, and are placed by various (end) customers, preferably online. These customer orders will hereinafter also be referred to as customer orders (or simply orders). The invention further relates to a delivery vehicle.

[0002] The invention relates in particular to both intralogistics and general logistics aspects. The intralogistics aspect lies in the assembly of items according to customer orders in a warehouse and order picking system. The general logistics aspect lies in the delivery of the already picked items from the warehouse and order picking system to the end customer ("home delivery") or to transfer stations (i.e., automated goods transfer stations for self-collection by the end customer, such as "Tower24") by means of a delivery vehicle. The invention is particularly applicable in the field of so-called "e-grocery".

[0003] It is already possible today to order items from a supermarket online and have the ordered items delivered to your home at a desired time or alternatively to a transfer station.

[0004] The order picking process (removal from storage location and delivery to destination, such as an order container assigned to the ordering customer) takes place in conventional storage and order picking systems, 100 of which are located in the Fig. 6 This is illustrated schematically. Order picking and (subsequent) delivery, excluding beverages and bulky goods, is carried out entirely in transport crates.

[0005] The Fig. 6 The following section describes in more detail the context in which the present invention operates. Fig. 6 In addition to structural components of the conventional System 100, functional aspects are also illustrated.

[0006] The items in the online supermarket's assortment are delivered to a receiving area 102 and distributed to various storage and picking areas 104 depending on the item type, as indicated by light (vertical) arrows in the Fig. 6 This is indicated. Within the storage and picking areas, examples include shelves 106, order pickers 108, and picking vehicles 110. The areas 104 are separated from each other (spatially and functionally) depending on the type of item.

[0007] Typical categories of an online supermarket generally include: valuables ("Value" such as cigarettes); dry goods ("Dry Goods" such as flour and sugar); cosmetics; household goods; bread; dairy products ("Dairy Products" such as milk, cheese and similar); fruit and vegetables ("Fruit & Vegetables"), sausage products ("Desk"); frozen products ("Frozen"); and beverages.

[0008] Dairy products, fruits and vegetables, and deli counter items are typically picked and transported in refrigerated crates or cooler boxes (112). Frozen products are picked and transported in freezer boxes (114).

[0009] Beverages do not need to be picked separately, as they are usually transported directly in their load carrier (e.g. beverage crate).

[0010] If a customer order includes items from different departments (104), the order is split into sub-orders (boxes) for picking in the respective departments. Sub-orders from the dry goods, cosmetics, issue, bread, dairy products, and fruit and vegetables departments are later consolidated (i.e., combined) in department 116 and sorted by customer. These items are then consolidated with the sub-orders from the remaining departments (104) in a shipping department (118) and sorted by delivery route.

[0011] Afterwards, the mostly pre-picked items (depending on the delivery route) are delivered in the boxes, as described in Fig. 6 This is indicated by block 120. Delivery 120 involves delivering the items to the end customer, which may require re-picking or consolidation with items from section 104 for frozen and chilled products. This means that the driver of the delivery vehicle (not shown) combines all items that do not require refrigeration with the items of an order that do. This is done when the items are unloaded from the vehicle, by transferring them from the crates into, for example, one or more bags.

[0012] Block 120 can also include the return or collection of empty containers by the driver.

[0013] Afterwards, empty containers, such as beverage crates and empty picking and transport crates, are returned. The transport crates then need to be cleaned. Cooling units must be removed for recooling. Empty beverage crates are sorted and then returned to the beverage manufacturer.

[0014] System 100 has the following disadvantages.

[0015] Synchronizing the various pre-picked sub-orders from different areas (104) is difficult to impossible. Multiple consolidations are frequently required at various points, meaning different sub-orders must be repeatedly merged. There is no consolidation of the picked items. This means that the items are often delivered in transport containers that are not completely full.

[0016] The consolidation and compression of picked items is also addressed in EP 2 872 424 B1. This document discloses a system and procedure for operators of an online supermarket where customers collect their orders directly from the warehouse and order picking facility.

[0017] Common changes to customer orders and delivery routes in e-commerce are difficult to implement. Changing a route, for example, might mean transferring a customer who was originally scheduled for delivery on one route to a second. This customer might be located precisely on the border between two delivery areas. Subsequent route optimization might reveal that it would be more efficient to deliver the customer on the second route.

[0018] It is already common practice to move (not shown) transport containers through areas 104 on the order picking vehicle 110. These transport containers can be decorated with (customer) bags, which are handed directly to the customer at the end of the delivery. A disadvantage is that a lot of space is wasted in the transport containers because each container only holds bags for a single customer.

[0019] Another disadvantage of this type of order picking is that different transport containers are used, resulting in transshipment processes that cost time.

[0020] To ensure error-free order picking, both the items and the picking elements used, such as the picking vehicles 110, are scanned multiple times very frequently.

[0021] The picking routes (walking routes) can be very long.

[0022] All of these factors contribute to the relatively inefficient order picking process. The fact that transport containers must be labeled multiple times (route, customer, etc.) also plays a role. Sorting by customer and route is labor-intensive.

[0023] The reloading of items at the delivery endpoint by the driver of the delivery vehicle is time-consuming, but unavoidable, because frozen and non-refrigerated items have to be brought together.

[0034] DE 10 2016 009563 A1 concerns a system and a mobile freight station for distributing, delivering and collecting freight.

[0035] Therefore, it is an object of the present invention to provide an improved system and method for picking and delivering items from an online supermarket.

[0036] This task is solved by a method for picking and delivering items according to a large number of customer orders, wherein the orders consist of baggable items from an online supermarket that the customers have ordered, comprising the steps of: providing a storage and picking facility in which the online supermarket's items are stored in, preferably different, storage and picking areas; filling bags with the ordered items in the storage and picking areas according to the orders; coupling the bags to an overhead conveyor; transferring the filled bags to a delivery vehicle equipped to transport the bags suspended; transporting the suspended bags to the customers with the delivery vehicle;Establishing a delivery route using a control device, wherein the delivery route defines a sequence in which customers are visited by the delivery vehicle in order to hand over the bags containing the items ordered by the customers; and sorting the filled bags according to the delivery route using the overhead conveyor.

[0037] The process described above is characterized by minimal contact with the ordered items (one-touch strategy). Specifically, this means that the items are only handled when the bags are being filled. Afterward, no further handling takes place. This means, in particular, that no reloading occurs either within the facility or by the delivery driver. The items are already in the bags that will later be handed to the customer. Picking into boxes and then transferring the items into bags or pouches is eliminated.

[0038] The use of bags simplifies sorting processes. One of these sorting processes is based on the delivery route. At the latest when the driver removes the bags from the delivery vehicle, the bags assigned to the current customer should be ready as a group. This means the driver doesn't have to search through all the bags in the vehicle. The bags needed are immediately available, for example, at a designated retrieval opening. The necessary sorting process is carried out during the journey from the facility to the customer. Alternatively, this sorting process can, of course, also be performed at the facility itself.

[0039] Another sorting process carried out within the facility allows for the allocation of bags (and thus orders) to specific delivery vehicles. Each delivery vehicle is assigned a delivery area or route, in which a specific group of customers resides. In other words, each delivery vehicle is assigned a fixed group of customers, which necessitates the distribution of bags within the facility to the vehicles in order to load them accordingly.

[0040] Another advantage lies in the consolidation. The bags can be automatically gathered from the various storage and picking areas into a central collection area using the overhead conveyor, where they are then sorted according to the sorting processes described above. For example, refrigerated goods remain in a refrigerated picking area until shortly before delivery.

[0041] Sorting and / or compaction processes can be carried out both within the facility and within the delivery vehicle. The ordered items are preferably handled exclusively in the hanging bags. Hanging bags can be compacted to their maximum extent by pushing the bags together until they are in contact. Such compaction is not possible with conventional containers, for example. With the traditional approach, if the container is not completely filled, space is wasted.

[0042] Furthermore, it is preferred if the overhead conveyor has a driven overhead conveyor system within the delivery vehicle, with which the step of sorting the filled bags according to the delivery route is carried out.

[0043] In this case, the bags belonging to a delivery route can be handled chaotically within the facility. Specifically, the bags can be transferred to the delivery vehicle in a random order. The delivery vehicle then arranges the bags according to the order in which the customers are visited. This results in a time saving because no sorting is required within the facility.

[0044] Furthermore, it is advantageous if the bags are transported hanging through the system while being filled with the items according to customer orders and / or while the bags are being handed over to the delivery vehicle.

[0045] In other words, this means that the bags within the system are always used in a suspended position. The bags are filled while suspended. They are also transferred to the delivery vehicle while suspended. As a result, the bags are continuously transported by the overhead conveyor. The order picker (packer) within the system does not need to carry the bags. Nor do the bags need to be transferred between different transport containers. The bags can be transported automatically during all process steps.

[0046] In another special design, the step of coupling the bags to the overhead conveyor only takes place when the filled bags are handed over to the delivery vehicle.

[0047] This design makes it possible to operate existing storage and order picking systems that do not have an overhead conveyor according to the invention. In this case, the bags can be moved through the system, for example, standing upright in transport containers, particularly to fill the bags with items. The filled bags can then be transported in the transport container to the delivery van, where they are loaded into the vehicle, either automatically or manually, while suspended.

[0048] As mentioned above, it is also advantageous if the bags within the facility are further sorted for different delivery vehicles, which are assigned different delivery routes.

[0049] In a further preferred embodiment, only a single type of bag is used for all steps, wherein the type of bag can preferably be coupled to the overhead conveyor via an adapter, in particular a bracket, a loop or the like.

[0050] This design allows (disposable or reusable) bags to be used as reusable shopping bags, which are later handed to the customer and remain with the customer. Therefore, no conveyor-specific bags are used, but rather conventional bags that are inexpensive and can be given to the customer.

[0051] The aforementioned task is further solved by a system for picking and delivering items according to a multitude of customer orders, wherein the orders comprise baggable items from an online supermarket that the customers have ordered, and wherein the system comprises: a storage and picking facility comprising at least one storage and picking area where bags are filled with the ordered items according to the orders; an overhead conveyor for sorting the filled bags according to a delivery route; at least one delivery vehicle equipped to transport the bags suspended from the vehicle; and a control device equipped to determine the delivery route, wherein the delivery route defines a sequence in which the customers are visited by the delivery vehicle in order to hand over the bags containing the items that the customers have ordered.

[0052] The advantages mentioned above in connection with the procedure apply analogously to the system.

[0053] Preferably, the overhead conveyor has a driven, in particular self-contained, overhead conveyor technology within the delivery vehicle.

[0054] Furthermore, it is advantageous if the overhead conveyor is provided in the system, especially in the at least one storage and picking area.

[0055] In this case, the order picker doesn't have to carry the bags. During filling, the bags are already attached to the overhead conveyor. This improves ergonomics for the order picker. Sorting and / or consolidation processes can be automated.

[0056] Furthermore, standard picking strategies, such as the man-to-goods principle, can be optimally applied. Batch-oriented picking is also possible.

[0057] Even the subsequent merging of bags belonging to the same order and originating from different storage and picking areas is simple and automated. Reloading processes are avoided. Sorting processes can be integrated.

[0058] In another special configuration, the overhead conveyor in the system features a driverless transport system with driverless transport vehicles, wherein the driverless transport vehicles are equipped to transport the bags suspended from the ground.

[0059] Existing systems that do not have a conventional (e.g., ceiling-mounted) overhead conveyor can be easily retrofitted in this way. The paths and / or space of existing conveyor systems can be used for the driverless transport system, thus realizing the advantages described above.

[0060] In particular, the overhead conveyor is designed to couple the bags via adapters, the bags being preferably sacks, and especially disposable sacks.

[0061] Preferably, the bags are alternatively reusable bags, which preferably have an integrated cooling system.

[0062] Furthermore, a delivery vehicle is proposed that has a powered overhead conveyor system and is set up to be operated in the system described above.

[0063] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0064] Exemplary embodiments of the invention are shown in the drawings and are explained in more detail in the following description. They show: Fig. 1 is a schematic configuration and flow diagram for a system and procedure for picking and delivering supermarket items ordered online; Fig. 2 is a schematic illustration of a picking operation in which an overhead conveyor is used to transport the picked items within a storage and picking area; Fig. 3 is a schematic illustration of a delivery vehicle loading operation; Fig. 4 shows a flow diagram of a picking and delivery procedure; Fig. 5 is a cutaway side view of a delivery vehicle; and Fig. 6 is a configuration and flow diagram for a conventional system and procedure for picking and delivering supermarket items.

[0065] The present invention relates to a system 10 and a method for picking and delivering articles 14 according to a plurality of customer orders. These customer orders comprise "pocket-sized" articles 14 from an online grocery retailer or online supermarket, such as fruits and vegetables, dairy products, meat and sausages, (frozen) refrigerated products, beverages, drugstore items, and / or household goods, and are placed by various (end) customers, preferably online via the Internet. These customer orders will hereinafter also be referred to as customer orders (or simply as orders).

[0066] Fig. 1 Figure 1 shows a schematic configuration and flow diagram to illustrate the present invention.

[0067] Shown is a system 10 with a storage and order picking system 11, which will subsequently be referred to simply as system 11. System 11 has at least one storage and order picking area 12. The storage and order picking areas 12, which belong to the areas 104 of system 100 of the Fig. 6 The areas that can be formed are usually arranged separately from each other. However, areas 12 can be directly adjacent to each other.

[0068] In the Fig. 1 System 10 exemplarily features n storage and picking areas 12, where n is an integer greater than 1. However, it is understood that only a single area 12-1 can be provided.

[0069] Generally, all "pocket-sized" items 14 are picked and packed into bags 16 (see also Fig. 2 ), whereas non-pocketable items, if they are even present in the product range, can be picked conventionally.

[0070] The term "baggable" expresses the fact that the items 14 are dimensioned so that they can be packed and transported in a bag or pouch 16 (not shown). The bags or pouches 16 are preferably handed directly to a customer 24 at the end of a delivery process, i.e., without (re)packing into a delivery container. In particular, the bag 16 is the delivery container itself, which is handed to the customer 24, as will be explained in more detail below. An example of a delivery container is a bag, preferably made of bioplastic, which, for example, has a maximum load-bearing capacity of 2 to 10 kg and a size of 35 x 35 x 4 cm to 50 x 40 x 5 cm. Alternatively, paper or fabric bags can be used.

[0071] A bag or pouch 16 is characterized by having a sack-like opening, open at the top, and at least one carrying handle. Other shapes, dimensions, and maximum load capacities are possible. The bags and pouches 16 can be equipped with an identification marker (e.g., RFID tag) to enable identification and eliminate the need for labeling. In this case, the bags 16 can be continuously read and tracked in the system 11, on the AGVs 42, and within the delivery vehicles 20.

[0072] Furthermore, the pocketable items 14 have a weight that does not exceed the maximum load capacity of the delivery container.

[0073] All items that are not pocketable, such as beverage crates, can also be handled in System 10, as will be explained in more detail below.

[0074] System 10 can also include an optional sorting area 18 to sort the bags 16 according to customer 24 (delivery route) and / or delivery zones or areas. The following example will focus exclusively on customer-based sorting. For this purpose, the orders are evaluated by a control unit 28 according to the customer addresses in order to determine the most optimal delivery route, i.e., the sequence of deliveries. The sequence determines which customer from a group of orders is served first and which customer is served last. Accordingly, the delivery vehicle 20 then serves the customers 24.

[0075] When determining a delivery route, preferred delivery times and similar factors can also be taken into account. Route and time optimizations are given priority.

[0076] Customer sorting can take place within Annex 11 and / or within the delivery vehicles 20, as will be explained in more detail below. Zone or area sorting, however, takes place in Annex 10, i.e., before the items 14 are loaded into one of the delivery vehicles 20, because the delivery vehicles 20 always deliver the items 14 to a specific area.

[0077] Similar to the conventional System 100, the items 14 within Annex 11 are preferably picked using a "zone-oriented" approach. This means, for example, that fruit and vegetables are picked in a first zone 12-1, whereas cigarettes (value) are picked in a second zone 12-2. During picking, the items 14 are taken from storage locations and placed in the bags 16. In this way, the bags 16 are filled.

[0078] It is understood that, depending on the quantity, dimensions, and weight of the ordered items 14 belonging to a (single) order, one or more bags 16 must be filled. This is determined in advance by an order management and processing system and communicated to the order picker 108 (order picking guidance).

[0079] Subsequently, all filled bags 16 belonging to the same customer 24 are sorted, i.e., merged. Merging is necessary if the order requires filling multiple bags 14 or if several orders are processed simultaneously (in parallel) within the system.

[0080] Typically, a large number of different orders are processed in parallel, necessitating order-oriented consolidation. It is understood that sorting would be unnecessary if all customer orders in system 11 were processed sequentially. Nevertheless, even in this case, bags 16 originating from different areas 12 but belonging to the same customer 24 would need to be consolidated.

[0081] Furthermore, it may be necessary for the bags 14 belonging to the same customer 24 to be delivered in a specific (absolute) order (e.g., heavier items first). This also necessitated sorting.

[0082] Once the bags 16 belonging to the same customer 24 have been brought together, these bags 16 can be handed over to a delivery vehicle 20, so that the bags 16 are stored in the delivery vehicle 20, preferably hanging.

[0083] The delivery vehicle 20 has either (passive) buffer rails (not shown) and / or an (actively driven, self-contained) overhead conveyor 22 for suspended storage of the pockets 14 (see figure). Fig. 2 , bottom right).

[0084] Returning to Fig. 1 Once the bags 16 are loaded onto the delivery vehicle 20, they will be transported to the customers 24. This transport is preferably carried out directly by the delivery vehicles 20, i.e., without a stop at another (not shown) distribution center where final route sorting could take place. Alternatively, the delivery vehicle 20 can also go to one of the aforementioned transfer stations (not shown here), where the customers 24 can pick up their orders themselves.

[0085] In Fig. 1 The transport of the bags 16 is carried out, for example, directly to a front door 26 of the customer 24. The driver 58 (see Fig. 3 The driver of delivery vehicle 20 removes the bags 16 from the delivery vehicle 20 and hands them over to the customer 24 at their front door 26 ("Home Delivery"). This therefore concerns, in particular, online commerce between a food retailer and private individuals.

[0086] As mentioned above, the delivery route is determined by control unit 28, which is located in Fig. 1 This is illustrated by a cloud and is part of system 10 (and / or plant 11). The control unit 28 can be implemented by a centrally or decentrally arranged data processing unit. The control unit 28 evaluates, for example, the residences of customers 24 in order to determine the delivery route.

[0087] The control unit 28 is further configured for at least one of the following functions: warehouse management; order management and processing; and material flow control within plant 11. The control unit 28 is implemented using hardware and / or software. The control unit typically includes at least one data processing system.

[0088] Parts of the control unit 28 or control software required for sorting can also be provided in the delivery vehicle(s) 20. Alternatively, the delivery vehicles 20 can be equipped with their own control units.

[0089] Returning to Fig. 1 The bags 16 filled with the articles 14 are sorted according to the delivery route, preferably using an internal vehicle overhead conveyor 22. This means that the driver 58 of the delivery vehicle 20, as soon as he arrives at the customer 24, places the bags 16 in a desired sequence at a dispensing opening 60 (see figure). Fig. 3 The driver 58 receives the bags 16 from the delivery vehicle 20. The driver 58 then only needs to unhook these bags 16 and hand them over to the customer 24. The driver 58 no longer needs to get into the vehicle 58 and search for the bags 16 assigned to the current customer 24. The driver 58 also no longer needs to reload the items 14. This means, for example, that the items 14 no longer need to be removed from boxes and repacked into the delivery bag that is then actually handed to the customer 24. This also applies to (frozen) refrigerated goods, as will be explained in more detail below.

[0090] Once the driver of delivery vehicle 20 has delivered to all customers 24 on his delivery route, he returns to facility 11. In facility 11, bags 16 that customer 24 may have returned can be cleaned in a cleaning station 30 of facility 11 and / or cooled in a cooling unit 32 (e.g., in a cold storage facility).

[0091] For cooling, the bags 16 preferably have either an integrated cooling system 34, which can be filled with a (not shown) cooling liquid, or replaceable cooling units 36. If a cooling liquid is used, the bags 16 can also be refilled with new cooling liquid as needed, preferably only immediately before being filled with the articles 14. In the Fig. 1 Meandering cooling lines are indicated, which may be integrated into pockets 16.

[0092] It is understood that both the cleaning station 30 and the cooling unit 32 are optional components of the system 11.

[0093] The Fig. 1 This illustrates System 10 and the processes for a single operator of an online supermarket. However, the system shown can also be applied to a large number of online supermarket operators, each serving a large number of customers. At least some customers of one operator can simultaneously be customers of another operator.

[0094] The various operators each run their own warehouse and order picking facility 11 and their own fleet of delivery vehicles 20. The picking of the articles 14 is carried out as described generally above and specifically below. The method of delivery differs.

[0095] The operator-specific delivery vehicles 20 do not drive directly to the customer 24, but deliver the bags 16 to a distribution center (not shown). The distribution center is also equipped with an overhead conveyor 22 (FTF 42 and / or overhead conveyor technology 44) to automatically load and unload the bags 16.

[0096] At the distribution center, the bags (16) from different operators can be sorted for a shared (operator-independent) delivery route. This sorting (or delivery route) is preferably based on route optimization. The goal is to deliver to as many customers (24) as possible via the shortest possible route, regardless of where a customer (24) placed their order.

[0097] In this case, tour optimizations occur (e.g., fewer stops for many customers) and bundling effects are achieved. Delivery times can be further reduced. Operators can share transport costs. Operators can mark their bags (16) with their own branding and have them delivered by a "neutral" transport company.

[0098] Fig. 2 illustrates, by way of example, one (single) of the storage and order picking areas 12 of the Fig. 1 The one in Fig. 2 The area shown, 12, is operated manually. This means that one or more order pickers 108 manually remove the items 14, for example, from a shelf compartment 38 of a shelf 40 and place the removed item(s) 14 into one or more of the bags 16.

[0099] The dispensing of the articles 14 preferably takes place directly into the bags 16, which are already suspended from an overhead conveyor 22 located in the Fig. 2 upper right by a driverless transport vehicle 42 and in the Fig. 2 The lower right is implemented in the form of an (actively driven) overhead conveyor system 44. Alternatively, the articles 14 can also be placed in pockets 16, which are, for example, in a (not shown) transport container mounted on a picking vehicle 110 (see below). Fig. 6 ) can be positioned, standing or sitting.

[0100] The order picking takes place in Fig. 2 Manually. Order picking is carried out according to the man-to-goods principle when items 14 are handed over to the AGV 42, whereby the AGV 42 autonomously follows a path 46, which may, for example, be marked on the floor along the shelf 40. In this case, the AGV 42 moves along the shelf 40 together with the order picker 108. It goes without saying that there are also variants of the AGV 42 that can navigate without a (visually recognizable) path.

[0101] The FTF 42 is equipped, for example, with a rack 48 where the bags 16 can be hung. The rack 48 is designed to transport several bags 16 simultaneously. Preferably, empty bags 16 are pre-hung in the rack 48, with each of the hung bags 16 later being assigned (data-wise) to one of the customer orders, at the latest when the first item 14 is placed into the empty bag 16. It is understood that the bags 16 can generally be equipped with individually distinguishable identification features (barcode, RFID tag, etc.).

[0102] The FTF 42 can also be configured to transport non-pocketable items, e.g., in a lower section of the FTF 42, on a transport platform 50 of the FTF 42. In the upper right area of ​​the Fig. 2 For example, two beverage crates are shown on transport platform 50 of the FTF 42. The beverage crates can be transported simultaneously with the bags 16 by the FTF 42 through area(s) 12.

[0103] Furthermore, it is understood that the FTF 42, preferably autonomously, should be able to move through the entire plant 11, and in particular through all areas 12.

[0104] The order picker 108 can carry empty bags 16 instead of an AGV 42, into which he places the items 14 according to the order. As soon as one bag 16 is full, the next bag 16 is filled. Later, or immediately after filling, the order picker 108 can deliver the full bag to an overhead conveyor 22.

[0105] It goes without saying that order picker 108 is involved in man-to-goods order picking (top right in Fig. 2 The order picker 108 is guided through area 12 by the control unit 28 in an order-oriented manner (and, if necessary, with optimized routes). For this purpose, the order picker 108 can be equipped, for example, with a (not shown) mobile data terminal or a headset (headphones and smart glasses). Alternatively, the order picker 108 can walk along the shelves 40 through area 12 with a printed picking list (customer's shopping list 24), which he carries with him in paper form.

[0106] In the lower right area of ​​the Fig. 2 A picking operation based on the "goods-to-person" principle is schematically indicated. In particular, a bag loading station 52 is shown. At the bag loading station 52, empty bags 16 can be transported to the picker 108 by means of a powered overhead conveyor 44 to be filled. In this case, the picker 108 does not pass through the areas 12. Simultaneously, storage containers 54 can be transported (synchronously) to the picker 108 via a conventional conveyor system (roller conveyor, belt conveyor, overhead conveyor, etc.) or via the AGV 42. In this case, the picker 108 is shown, for example, on a screen 56, which item 14 he is to take from the provided storage container 54. Furthermore, the picker 108 can be shown the number of items 14 to be taken. Preferably, only one item 14 is taken at a time and placed into a single bag 16.This approach, however, requires a subsequent sorting process where the (individual) items picked – in this case item-oriented – are then sorted according to the order. This is referred to as two-stage picking or batch picking.

[0107] Instead of feeding the storage containers 54, the loading station can also be used to couple full bags 16, which have been filled as described above, to the overhead conveyor 22 or the driven conveyor 44, i.e., preferably to hang them there. For this purpose, the (collecting) bags can be suspended, as will be explained in more detail below.

[0108] Alternatively, the one in the lower right area of ​​the Fig. 2 The (stationary) loading station 52 shown can also be omitted. This applies generally to all areas 12. The overhead conveyor system 44 can run through areas 12, in particular along and parallel to the shelves 40, so that the order picker 108, who in this case again picks according to the man-to-goods principle, can place the items 14 taken from the shelf compartments 38 directly into an already suspended bag 16. It is understood that in this configuration order-oriented (i.e., single-stage) picking is preferably carried out.

[0109] Furthermore, it is generally understood that order picking does not necessarily have to be done manually. Instead of a picking robot 108, robots (not shown) can also be used, which are either positioned at a stationary location (analogous to the bag loading station 52) for picking and transferring items, or which – similar to the AGVs 42 – can move autonomously through the areas 12 to reach the storage locations. The robots are configured to deliver picked items 14 directly to the bags 14.

[0110] Finally, it goes without saying that order picking can be carried out in one or two stages. Hybrid forms are also possible.

[0111] As mentioned above, the bags 16 can generally be implemented using, for example, bags that are clamped into overhead conveyor-compatible (not shown) brackets or loops (i.e., adapters). These adapters can be so-called roll adapters, as shown in examples in documents DE 297 09 545 U1 or DE 297 09 547 U1, which are referenced here. These roll adapters have an opening into which the bracket can be inserted. This bracket is designed, for example, to clamp or hook the bag 16's holders so that the bag 16 can be filled. The bags can later be handed directly to the customer 24, even though they can be transported automatically using the overhead conveyor 22 (e.g., the AGV 42 or the overhead conveyor system 44).

[0112] Alternatively, (disposable) bags can be positioned in overhead conveyor-specific pockets 16 (see, for example, DE 10 2011 101 987 A1, DE 10 2011 015 138 A1 or DE 10 2012 018 925 A1), with the bags then being removed from the pockets 16 and handed over by the driver 58 only at the customer 24. The overhead conveyor-specific pockets 16 are not handed over to the customer 24.

[0113] As already mentioned, the (disposable) bags can also be transported through area 12 inside the (not shown) transport containers. In this case, the transport containers are transported, for example, by the AGVs 42 through system 11 and, in particular, through area 12. These bags can be coupled to the overhead conveyor 22 at a later time by, for example, clamping them into appropriately designed brackets. Coupling the bags to the overhead conveyor 22 is particularly necessary when the bags still need to be sorted.

[0114] Fig. 3 Figure 1 schematically shows the transfer of bags 16 from system 11 into one of the delivery vehicles 20. The driven overhead conveyor system 44 is shown as an example, which fills the delivery vehicle 20 with hanging (full) bags 16 (order-oriented, but possibly still unsequenced). Empty bags 16 can also be unloaded from the delivery vehicle 20 using the driven overhead conveyor system 44.

[0115] It goes without saying that the FTF 42 with the racks 48 can be used as an alternative or supplement to the loading. In the example of the Fig. 3 The FTF 42, for example, only delivers non-pocketable items, such as beverage crates, to delivery vehicle 20 and takes empty items back with them on their return journey.

[0116] The delivery vehicle 20 is equipped with (passive, not shown) rails as an alternative or supplement to the driven conveyor 44. The bags 16 can be pushed onto the rails from the overhead conveyor 22 of the system 11. In this case, the loading of the rails is preferably already route-oriented. This means that the bags 16 are loaded into the delivery vehicle 20 in the delivery sequence (FIFO, first in, first out) as they will later be unloaded by a driver 58 at the customer's location 24.

[0117] If the delivery vehicle 20 is also equipped with a driven overhead conveyor system 44, which is separate from the overhead conveyor system 44 of system 11 but can be coupled to the overhead conveyor system 44 of the delivery vehicle 20, then the route sorting can also take place while the delivery vehicle 20 is traveling to customer 24. Sorting can even take place while traveling between two different customers 24. The sorting is then carried out in such a way that the bags 16 (order-oriented) of the next customer 24 being approached can be removed from the retrieval opening 60 of the delivery vehicle 20.

[0118] It is understood that the loading of the delivery vehicle 20 with the bags 16 can alternatively also be done manually. The bags 16 do not necessarily have to be supplied to the delivery vehicle 20 via an overhead conveyor 22. The bags 16 can, for example, also be transported to the delivery vehicle 20 in the transport container mentioned above, where the driver 58 attaches the bags 16 to the rails mentioned above and / or to the powered circulating overhead conveyor system 44 of the delivery vehicle 20.

[0119] In addition to the removal opening 60 for the hanging bags 16, one or more loading / unloading openings 62 can be provided for the non-baggageable items. In the example of the Fig. 3 These openings 62 are, for example, arranged in a lower lateral area of ​​a cargo space of the delivery vehicle 20, so that the AGV 42 can preferably (partially) automatically load and unload the delivery vehicle 20 with the non-pocketable items.

[0120] As mentioned above, the bags 16 used within the plant 11, and possibly also in the delivery vehicles 20, are identical to delivery bags provided to the customer 24 for their unrestricted use. This means that preferably only a single type of bag 16 is used within the entire system 10, and the bags 16 are not necessarily returned by the customer 24 to the operator of the system 10. These delivery bags are specifically designed to be compatible with conveyor systems. This means that the delivery bags can be connected to existing overhead conveyors 22. Whether the connection is direct or indirect via an adapter is of secondary importance.

[0121] It is particularly advantageous if the bags 16 are transported exclusively suspended throughout the entire process. This reduces the number of handling operations associated with transferring the bags 16 between different transport and conveying systems. The items 14 are preferably only actively handled during order picking. All other steps are preferably automated.

[0122] The use of a powered overhead conveyor system 44 within plant 11, particularly within areas 12 and / or 18, as well as within the delivery vehicles 20, is especially advantageous. The order pickers 108 and / or drivers 58 do not have to carry or push the items 14. The order pickers 108 can pick the items 14 directly into the pockets 16.

[0123] Drivers 58 do not need to sort or reload the bags 16. They can remove the bags 16 from the dispensing opening 60 in the correct order, at the latest when they arrive at customer 24's home. If a universally usable bag 16 is not used, drivers 58 can, of course, reload the items picked into the bags 16 at the dispensing opening 60.

[0124] Another advantage can be seen in a cooling-capable bag 16. As mentioned at the beginning, the bags 16 can be equipped with an integrated cooling system 34. The integrated cooling system 34 can comprise a variety of pipes within the wall of the bag 16. The coolant can be routed through these pipes, cooled at a remote location, and exchanged for coolant that is (warm) contained within the bag 16.

[0125] Another advantage of using bags 16 is that the bags 16, or rather the picked items 14, can be compacted. A higher storage and transport density can be achieved compared to ordinary containers. For example, bags 16 of varying lengths can be used, so that the items 14 are at different heights within the filled bags 16. This allows for the utilization of space for compaction that would not be available when using ordinary transport containers (or bags 16 of a single length). It also prevents refrigerated and non-refrigerated items 14 from coming into contact with each other.

[0126] The same advantage naturally applies to the delivery vehicles 20. The delivery vehicles 20 are in particular equipped with an overhead conveyor system 44, which is arranged on several levels above and below each other.

[0127] Preferably, the items 14 themselves can already be configured to be suspended. This means that the items 14 can be directly coupled to the overhead conveyor 22 – without a bag 16. A six-pack of beverage cans, for example, could be additionally equipped with a transport eyelet to couple the beverage carrier directly to the overhead conveyor 22. The beverage carrier is then treated like a bag 16.

[0128] The delivery vehicles 20 can be loaded and unloaded extremely quickly when overhead conveyors 22 are used. Loading and unloading is largely automated.

[0129] Fig. 4 Figure 1 shows a flowchart of a process for picking and delivering items 14 according to a multitude of orders from customers 24, where the orders consist of pocketable items 14 from an online supermarket ordered by customers 24. The sequence of steps shown is not fixed. The sequence can be changed and depends in particular on whether and which material handling equipment is used in a system 11 and how picking is carried out in the system 11 (man-to-goods, goods-to-man, single-stage, two-stage, batch picking, pick-by-light, etc.).

[0130] In a first step S10, the storage and picking system 11 is provided, in which the articles 14 of the online supermarket are stored in, preferably different, storage and picking areas 12.

[0131] System 11 is configured as described above. Areas 12 differ primarily in the types of items stored and picked there. For example, refrigerated products must be stored at lower temperatures than dry goods. Refrigeration is technically complex and more expensive. Other products, such as cigarettes, must be protected against theft. Still other products must be protected against unauthorized access.

[0132] In a further step S12, the bags 16 are filled with the ordered items 14 in the storage and picking areas 12 according to the orders. Preferably, the bags 16 are already suspended from the overhead conveyor 22 at this point, which runs through all areas 12, so that the bags 16 can be filled successively in all areas 12. However, the bags 16 can also be filled in a different state, e.g., while sitting in a container.

[0133] In step S14, the bag 16 is coupled to an overhead conveyor 22. This can happen before or after filling.

[0134] This can also happen only upon handover to a delivery vehicle 20.

[0135] In step S16, the filled bags 16 are handed over to the delivery vehicle 20, which is set up to transport the bags 16 hanging.

[0136] In step S18, the hanging bags 16 are transported to the customers 24 using the delivery vehicle 20.

[0137] In step S20, a delivery tour is determined by means of a control device 28, whereby the delivery tour defines a sequence in which the customers 24 are visited with the delivery vehicle 20 in order to hand over the bags 16 including the items 14 that the customers 24 have ordered.

[0138] This step can be the very first step. The control system can analyze all incoming customer orders in advance according to delivery locations (i.e., the residences of customers 24) in order to determine, for example, a route-optimized delivery tour (navigation route). In this context, delivery times requested by customers 24 and similar factors can also be taken into account, although in most cases the tour is then no longer optimized for route but for time. The delivery tour, in particular, defines all subsequent processes (order picking, delivery vehicle, etc.).

[0139] In step S22, the filled bags 16 are sorted according to the delivery route using the overhead conveyor 22.

[0140] This sorting can take place in plant 11 and / or in the delivery vehicle.

[0141] In a step not shown, the filled bags are then handed over to the customer by a driver 58 of vehicle 20.

[0142] The process then ends.

[0143] Fig. 5 Figure 1 shows a cutaway side view of an exemplary delivery vehicle 20, which has a driven overhead conveyor system 44 that is independent of the overhead conveyor system 44 of Annex 11. The delivery vehicle 20 itself constitutes an independent invention.

[0144] Within a cargo space 64 of the delivery vehicle, means are provided for suspending the (filled) bags 16. These means can be implemented by passive rails (not shown) and / or at least one powered overhead conveyor system 44.

[0145] The overhead conveyor system 44 for the delivery vehicles 20 can be installed modularly in one piece into each of the vehicles 20 and mechanically and electrically connected there. This can be a one-time installation process and / or a recurring (quick) process to allow for the use of different subcontractors. If desired, these overhead conveyor modules can also be pre-equipped with pockets 16 for delivery.

[0146] In the Fig. 5Two overhead conveyor systems 44 are provided on different levels E1 and E2 to fully utilize the capacity of the cargo space 64. Each of the overhead conveyor systems 44 is preferably self-contained and may have one or more (not shown) auxiliary sections to enable sorting processes. It is understood that only a single conveyor system 44 could also be provided. Alternatively, more than two overhead conveyor systems 44 can be provided, in particular to allow for spatially separated, cooled and uncooled areas within the cargo space 64. Preferably, the overhead conveyor systems 44 are (vertically) connected to each other to allow for the exchange of pockets 16.

[0147] Below level E2, there is sufficient space to store and transport non-portable items, such as crates of beverages, on the floor of cargo space 64. Generally, any space within cargo space 64 can be used to store and transport non-portable items. Non-portable items can also include (postal) parcels from other delivery services.

[0148] Furthermore, the delivery vehicle 20 is equipped with an interface (not shown) to couple the overhead conveyor system 44 of the system 11 for the automatic filling of the vehicle 20 with the bags 16 to the overhead conveyor system 44 of the vehicle 20.

[0149] The delivery vehicle 20 is also equipped with a (not shown) control system to automatically sort the bags 16, especially during a journey to the customers 24.

[0150] The cargo space 64 of vehicle 20 could also be configured as a separable container that can be used as a mobile (i.e., non-stationary) temporary transfer station. The container could be set up, for example, in residential areas, at airports, in parking garages, public transport stops, and other locations, allowing customers 24 to personally collect their orders at the collection point 62 (e.g., using a code). The collection point 62 would need to be equipped accordingly (interaction terminal, power supply, etc.). In this case, the integrated overhead conveyor system 44 would need to be equipped with a sorting function because the order in which customers 24 collect their orders is unpredictable.

[0151] The advantages of the system 10 and / or procedure described above are summarized below. One-touch strategy:

[0152] Direct order picking into delivery bags (in all areas 12); elimination of order picking vehicles 110; elimination of transport boxes and thus of transshipment processes; elimination of pre-filling of transport boxes with bags 16; elimination of handling of empty transport containers, in particular their return; and reduced labeling. Optimized order picking:

[0153] Use of FTF 42 in large-scale areas 12 (long walking distances for order pickers 108 eliminated by zone picking, whereby area 12 is divided into zones that are operated flexibly or according to the requirements of order pickers 108); increased access rate for order pickers 108 and reduction of throughput time; optimized and dynamic order prioritization; direct buffering, storage and sequencing in the respective (cooled) areas 12; and gentle item handling and reduction of reloading processes. Refill / replenishment processes:

[0154] (Partially) automated replenishment (transport, provision, allocation) using the AGV 42; guidance of the order picker 108 via portable data terminal (e.g., Pick-by-Watch); and efficient placement of items in storage devices within areas 12 including waste disposal (using the FTF42). Technology and logistics:

[0155] Overhead conveyor 22 for consolidation, buffering, storage and / or sequencing or sorting (delivery vehicle 20 and / or route); buffering of already picked chilled items 14 takes place directly in the chilled areas 12; identification, tracking, re-sorting and / or documentation by means of identification markers in or on the bags 16; automated sorting according to delivery vehicles 20 and delivery routes immediately before loading the vehicles 20; very fast loading and unloading of the vehicles 20; use of special bags 16 (e.g. including cooling system 34, padding, inserts, etc.) possible; elimination of ice pack handling; and significant improvement in volume utilization. Delivery:

[0156] Delivery vehicles 20 are equipped for suspended transport of bags 16, thus simplifying sorting; optimal space allocation (bags 16, cartons, beverage crates, bulky goods, etc.) is possible in the loading area 64; sorting is possible while driving; ergonomic provision of the items 14 to the customer 24 for the driver 58, thus particularly reducing stopping time; and very short, automated unloading of the vehicles 20.
