Description

BACKGROUND OF THE INVENTION Area of ​​the invention

[0001] The present invention relates to an article management system that manages articles automatically and easily and ensures the convenience of the delivery service by automating article delivery. Description of the related technique

[0002] Recently, mobility vehicles have been developed that can be used in various fields, such as freight containers and medical transport. Mobility vehicles with improved energy efficiency have been developed and have reached the stage of practical application.

[0003] Furthermore, the mobility vehicle was developed to perform autonomous driving flawlessly, and various types of services, including delivery services, are available through the mobility vehicles that can perform autonomous driving flawlessly.

[0004] To implement the delivery service, a room for sorting and managing items is required, as well as an automated system for this purpose. Specifically, items will be classified based on temperature: those that must be stored and handled at room temperature, those that must be refrigerated, and those that must be frozen. Furthermore, items will be categorized according to their fragility, size, and other similar criteria. Currently, items must be sorted according to their specific storage requirements before delivery.

[0005] Therefore, there is a need to automate item management in a facility for sorting and maintaining items.

[0006] Furthermore, from US 2019 / 0329691A1, an article management system is known, comprising: an electric cart configured to load an article onto it and designed to be movable; a cart storage facility configured to store the electric cart on it; and a controller configured to communicate with the electric cart and to control and move the electric cart to a preset destination.

[0007] US Patent 10241516B1 discloses autonomous ground vehicles (AGVs) that can be deployed from facilities (e.g., material handling facilities) to deliver items to specific locations (e.g., users' residences). In various implementations, AGVs can utilize different techniques for long-distance travel between material handling facilities and delivery locations (e.g., solar charging, strategically placed charging stations, energy-efficient driving). In various implementations, AGV facilities (e.g., smaller types of material handling facilities) can be sized to be more easily accommodated in densely populated urban areas (e.g., to be closer to various delivery locations) and can serve as home bases where AGVs are stationed and / or where items (e.g., from transport vehicles) are received for delivery to local delivery locations.

[0008] US Patent 10,315,674 B2 describes a portable storage device comprising a storage body with multiple sides enclosing a space suitable for storing items, and a wheel assembly attached to the storage body that enables the portable storage device to be moved across a surface. The wheel assembly includes one or more wheels pivoting on axle assemblies. During storage or use of the portable storage device, the wheels can be pivoted inward into a storage position. When the user is ready to move or transport the portable storage device on its wheels, the wheels can be pivoted outward.

[0009] The JP 4 418 381 B2 also shows a charging station for a battery in an autonomous mobile robot, which has a charging terminal for a battery provided in a housing and is configured to be movable by means of two independently driven drive wheels and at least one driven auxiliary wheel.

[0026] In the figures, the reference numbers throughout the various figures of the drawing refer to the same or equivalent parts of the present invention. DETAILED DESCRIPTION

[0027] Various embodiments of the present invention(s) will now be discussed in detail, examples of which are illustrated in the accompanying drawings and described below. While the present invention(s) will be described in conjunction with exemplary embodiments, it will be clear that this description is not intended to limit the present invention(s) to these exemplary embodiments. Rather, the present invention(s) is intended to cover not only the exemplary embodiments but also various alternatives, modifications, equivalents, and other embodiments that may be contained within the nature and scope of the present invention as defined by the accompanying claims.

[0028] Below, an article management system according to various exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0029] Fig. Figure 1 is a configuration view that exemplifies an article management system according to various exemplary embodiments of the present invention, which Fig. 2 and Fig. Three views are shown to explain a situation in which an electric car is loaded into a car storage facility, which Fig. 4 and Fig. 5 are views to illustrate a situation in which the electric car is being unloaded from the car storage facility, Fig. 6 is a view that illustrates the wagon storage facility by way of example, Fig. 7 is a view that illustrates an example of a lower end section of the wagon bearing device, Fig. Figure 8 is a cross-sectional view along a line AA to illustrate a fastening unit of a body section and a connecting unit of the carriage bearing device, and Fig. Figure 9 is a cross-sectional view along a line BB to illustrate a power source unit of the body section and a loading unit of the wagon storage facility.

[0030] As in Fig. Figure 1 illustrates an article management system according to various exemplary embodiments of the present invention comprising the following: electric trolleys 100 configured for loading articles onto them and designed to be movable; a trolley storage device 200 configured for storing the electric trolleys 100 and charging the stored electric trolleys 100 with electrical energy; and a controller 300 configured to communicate with the electric trolleys 100 and to control and move the electric trolleys 100 to a preset destination.

[0031] In this case, the electric cart 100 can move autonomously and has a loading space for the item. The electric cart 100 can have a specific storage function, which is defined according to a storage condition for the item. For example, the electric cart 100 can be configured to set a temperature for loading an item that requires a specific temperature. Furthermore, the electric cart 100 can be configured to dampen shocks, allowing an item to be loaded with a minimized impact. Alternatively, the electric cart 100 can be configured to divide the space according to the size of the item.

[0032] Meanwhile, the car storage facility 200 is configured to sort and store the electric cars 100 and to charge the charged electric cars 100 with electrical energy. That is, the electric cars 100 are sorted and stored in the car storage facility 200, which facilitates the management of the electric cars 100.

[0033] This means that multiple electric trolleys (100) are provided, and these trolleys are sorted according to their respective items and have different charging functions. The trolley storage system (200) divides the storage space into one area for storing electric trolleys (100) with the same charging function and another area for storing electric trolleys (100) that need to be moved to the same location.

[0034] Since the multitude of electric trolleys 100 have different charging functions, as described above, it is possible to provide a user with the electric trolley 100 that meets the condition for storing the item.

[0035] Furthermore, the trolley storage facility 200 is also provided in multiple configurations. The storage area includes space for storing electric trolleys 100 with the same charging function and space for storing electric trolleys 100 that need to be moved to the same location. Therefore, the electric trolleys 100 are easily managed. This means that the trolley storage facility 200 can subdivide the storage area according to the size of the electric trolley 100, its charge level or state, the storage environment, the delivery location, and the like. In addition, the trolley storage facility 200 can have special functions, such as cleaning or sterilization.

[0036] As described above, the multiple electric trolleys (100) are sorted according to their loading requirements. Therefore, it is possible to store items with differing storage conditions in the electric trolleys (100), and the items stored in the electric trolleys (100) also meet the storage requirements. Furthermore, the trolley storage system (200) is also provided in multiples, and the multiple trolley storage systems (200) store the sorted electric trolleys (100), thus facilitating the management of the electric trolleys (100).

[0037] The control unit 300 can communicate with the electric trolley 100 and control it, moving it to a preset destination. That is, the control unit 300 enables the electric trolley 100 to be moved to and stored in the trolley storage facility 200, or to move the electric trolley 100 to a delivery location.

[0038] Furthermore, the controller 300 can sort the electric trolleys 100 into those electric trolleys 100 that have the same charging function and those electric trolleys 100 that are to be moved to the same destination. The controller 300 can preferably move the electric trolleys 100 that are positioned close together, thereby improving the efficiency of the delivery of the electric trolleys 100.

[0039] The electric vehicle 100 according to various exemplary embodiments of the present invention will be described. As in the Fig. 1 to Fig. As illustrated in Figure 2, the electric cart 100 can include a body section 110 which has a cargo space for loading an item, and electric wheels 120 which are provided at the lower end section of the body section 110 and are configured to operate under control of the control system.

[0040] This means that the electric trolley 100 contains the body section 110 and the electric wheels 120. The body section 110 has the loading compartment into which the item is loaded. The body section 110 can have a specific loading function. In this case, the loading function could be a function for setting a temperature in the loading compartment, a function for damping a shock, a sterilization function, or the like. Different loading functions can be applied to the respective electric trolleys 100, and the electric trolley 100 suitable for storing the item can be assigned.

[0041] The electric carriage 100 has electric wheels 120, which are provided at the lower end of the body section 110. The electric carriage 100 is moved by actuating the electric wheels 120. The electric wheels 120 can be actuated by an internal motor and can be fitted with a steering function that moves the electric carriage 100 into a specific position. Furthermore, the electric carriage 100 communicates with the control unit 300, and the electric wheels 120 operate under the control of the control unit 300.

[0042] Therefore, the article can be loaded onto the body section 110 of the electric carriage 100 and moved, while the electric carriage 100 is moved into the specified position by actuating the electric wheels 120.

[0043] As in Fig. As illustrated in Figure 2, a receiving groove section 111, which is recessed to receive the electric wheel 120, is formed on the lower end section of the body section 110, and the electric wheel 120 is rotatably provided in the receiving groove section 111. Therefore, the electric wheel 120 is received in the receiving groove section 111 when the electric carriage 100 is loaded into the carriage storage facility 200. The electric wheel 120 rests on the floor surface when the electric carriage 100 is unloaded from the carriage storage facility 200.

[0044] As described above, the receiving groove section 111 can be formed at the lower end section of the body section 110, and the electric wheel 120 can be rotatably provided and received in the receiving groove section 111. Of course, the electric wheel 120 can be received in or removed from the receiving groove section 111 by a vertical movement instead of a rotational movement. Sufficient installation space must be ensured at the lower end section 220 of the body section if the electric wheel 120 is configured to perform the vertical movement. Furthermore, if the electric wheel 120 performs the vertical movement, its movement can be restricted while the electric wheel 120 is engaged by the carriage support device 200 when the electric carriage 100 is moved into the carriage support device 200 and loaded.Therefore, the electric wheel 120 is configured to perform the rotary motion, which allows the electric carriage 100 to easily enter the carriage storage facility 200.

[0045] Since the receiving groove section 111 is formed in the body section 110 and the electric wheel 120 is rotatably mounted in the receiving groove section 111, the electric wheel 120 can be mounted in or removed from the receiving groove section 111. Therefore, when the electric carriage 100 is loaded into the carriage storage device 200, the electric wheel 120 is mounted in the receiving groove section 111 while the latter is rotated. Thus, the electric carriage 100 can easily enter the storage space of the carriage storage device 200. Furthermore, when the electric carriage 100 is unloaded from the carriage storage device 200, the electric wheel 120 is rotated to be removed from the receiving groove section 111 and brought into contact with the base. Therefore, the body section 110 can be moved into the desired position by actuating the electric wheel 120.

[0046] In the present case, a locking device 112 can be provided for selectively fixing the rotational position of the electric wheel 120 in the body section 110. The locking device 112 can be provided on the body section 110 and connected to a rotating shaft of the electric wheel 120, thereby selectively fixing the position of the electric wheel 120.

[0047] The electric wheel 120 can, for example, be configured as a drive wheel that is rotated by the motor and the rotating shaft, which is rotatably mounted on the lower end section of the body section 110. In this case, the rotating shaft can be configured to receive a spring force from a spring and rotate in a direction toward the base. Furthermore, the locking device 112 can include a locking pin configured to extend or retract magnetically and fix the rotating shaft in a specific position. A structure for changing the rotational position of the electric wheel 120 and a structure for fixing a position of the electric wheel 120 using the locking device 112 can be implemented differently, as long as these structures serve the same purpose.

[0048] Meanwhile, a sensor unit 113 can be arranged on the body section 110 and detect whether the electric carriage 100 is being moved and loaded into or unloaded from the carriage storage device 200. The sensor unit 113 is provided at the lower end section of the body section 110 and detects whether the body section 110 is being loaded into or unloaded from the carriage storage device 200. Various sensors, such as a contact sensor or a laser sensor, can be used. In several exemplary embodiments of the present invention, the sensor unit 113 is provided on the side of the electric wheel 120 and configured to detect contact with the carriage storage device 200.

[0049] When the sensor unit 113 sends a signal to the locking device 112 indicating that the electric car 100 is being loaded into or unloaded from the car storage unit 200, the locking device 112 releases the electric wheel 120. That is, when the electric car 100 is moved and loaded into the car storage unit 200, the sensor unit 113 detects the loading of the electric car 100 and transmits a signal to the locking device 112. The locking device 112 then releases the electric wheel 120 so that it can be received in the receiving section 111. Furthermore, when the electric car 100 is moved and unloaded from the car storage unit 200, the sensor unit 113 detects the unloading and transmits a signal to the locking device 112.The locking device 112 releases the electric wheel 120, so that the electric wheel 120, which was received in the receiving groove section 111, is removed from the receiving groove section 111 and placed on the ground surface. In this case, the signal detected by the sensor unit 113 can be transmitted to the controller 300, and then the controller 300 can input an instruction into the locking device 112.

[0050] Meanwhile, a roller unit 250 is provided on the carriage support device 200. When the electric carriage 100 is loaded, the roller unit 250 supports the electric carriage 100 and assists in moving it as it rotates. The electric carriage 100 can be moved into the storage space by rotating the roller unit 250 in the position where the electric wheel 120 is received in the receiving groove section 111 of the body section 110. In this case, the roller unit 250 can be rotated by a separate motor, allowing the body section 110 of the electric carriage 100 to move into a storage position in the storage space.

[0051] If the electric car is 100, as in Fig. As illustrated in Figure 2, when the vehicle is loaded into the storage unit 200, the sensor unit 113 detects the storage unit 200, so that the locking device 112 releases the electric wheel 120. As shown in Figure 2, the sensor unit 113 detects the storage unit 200, so that the locking device 112 releases the electric wheel 120. Fig. As illustrated in Figure 3, the electric wheel 120 of the electric carriage 100 is therefore pressed through the carriage bearing assembly 200 and received in the receiving groove section 111 of the body section 110. Furthermore, the electric carriage 100 can be moved into the bearing position by rotating the roller unit 250, which is provided on the carriage bearing assembly 200.

[0052] If the electric car is 100, as in Fig. As illustrated in Figure 4, while unloading is taking place from the wagon storage unit 200, the sensor unit 113 can detect that the electric wagon 100 is moving and being unloaded from the wagon storage unit 200. Therefore, the locking device 112 releases the electric wheel 120 so that the electric wheel 120 can rotate. As shown in Figure 4, the sensor unit 113 can detect that the electric wagon 100 is moving and being unloaded from the wagon storage unit 200. Therefore, the locking device 112 releases the electric wheel 120 so that the electric wheel 120 can rotate. Fig. As illustrated in Figure 5, the electric wheel 120 is therefore moved in the direction in which the electric carriage 100 is unloaded from the carriage support device 200, so that the electric wheel 120 is rotated towards the ground surface and rests on the ground surface when the electric wheel 120 is separated from the carriage support device 200. Therefore, the electric carriage 100 can be moved while the electric wheel 120 is rolling.

[0053] As in Fig. As illustrated in Figure 6, the wagon storage facility 200 has the storage space for storing the electric wagon 100. A door 211 is provided on an upper end section 210 of the wagon storage facility 200 in a way that allows it to be opened and closed, and a lower end section 220 of the wagon storage facility 200 can be designed to engage the electric wheel 120 of the electric wagon 100.

[0054] Since the door 211 is designed to be opened and closed at the upper end section 210 of the wagon storage facility 200, it is prevented that the electric wagon 100, which is being loaded into the wagon storage facility 200, obstructs the open door 211. The door 211 can be opened or closed at the upper end section 210 of the wagon storage facility 200 by turning, sliding, or folding it down.

[0055] When the electric car 100 reaches the car storage facility 200, the electric car 100 and the car storage facility 200 identify each other. If the electric car 100 and the car storage facility 200 identify each other normally, the door 211 opens so that the electric car 100 can be stored in the storage space. Therefore, the car storage facility 200 only stores the identified electric car 100 in the storage space. This prevents the electric car 100 from being stored via an alternate route or from entering the storage space due to an error.

[0056] Meanwhile, the lower end section 220 of the wagon storage device 200 is designed to engage the electric wheel 120 of the electric wagon 100. That is, the lower end section 220 of the wagon storage device 200 can have a height that engages the electric wheel 120 when the electric wagon 100 is moved to be loaded into the wagon storage device 200. Since the electric wheel 120 of the electric wagon 100 is engaged and folded in by the lower end section 220 of the wagon storage device 200 when the electric wagon 100 is loaded into the wagon storage device 200, the electric wagon 100 can easily enter the wagon storage device 200.

[0057] As in the Fig. 7 to Fig. As illustrated in Figure 8, a fastening unit 114 is provided on the lower end section of the body section 110 and a connecting unit 230 is provided on the carriage bearing device 200 such that the connecting unit 230 is connected to the fastening unit 114 in order to fix the body section 110 when the electric carriage 100 is loaded and moved into the storage position.

[0058] Therefore, when the electric trolley 100 is loaded into the trolley storage device 200, the connecting unit 230 of the trolley storage device 200 is connected to the fastening unit 114, which is provided on the lower end section of the body section 110, so that the electric trolley 100 can be fixed in the storage position of the trolley storage device 200. The fastening unit 114 of the electric trolley 100 can be provided in the form of a groove, and the connecting unit 230 of the trolley storage device 200 can be provided in the form of a pin configured to extend in an upward / downward direction from the lower end section 220.

[0059] The trolley storage device 200 can include a sensor configured to detect whether the electric trolley 100 is positioned in a precise storage position. If the sensor detects that the electric trolley 100 is in the precise storage position, the connecting unit 230 can be connected to the fastening unit 114 in such a way that the position of the electric trolley 100 can be fixed in the storage space.

[0060] As in the Fig. 7 and Fig. As illustrated in Figure 9, a power source unit 115 is provided at the lower end section of the body section 110, and the carriage storage device 200 has a charging unit 240 which is configured to be connected to the power source unit 115 and to provide electrical energy when the electric carriage 100 is loaded and moved into the storage position.

[0061] When the electric car 100 is loaded into the car storage facility 200, the charging unit 240 of the car storage facility 200 can therefore be connected to the power source unit 115, which is provided at the lower end section of the body section 110, thereby charging the electric car 100 with electrical energy. The power source unit 115 of the electric car 100 and the charging unit 240 of the car storage facility 200 can be configured as power connections or configured to charge the electric car 100 wirelessly.

[0062] At the time of charging the electric carriage 100 in the carriage storage facility 200, the power source unit 115 and the charging unit 240 are used to charge the electric carriage 100 in the state in which the electric carriage 100 is loaded into the carriage storage facility 200 and the electric carriage 100 is then fixed by the connection between the connecting unit 230 and the fastening unit 114.

[0063] As in Fig.As illustrated in Figure 1, the article management system further includes a delivery mobility vehicle 400, configured for autonomous movement and featuring a receiving area. The delivery mobility vehicle 400 can be an air mobility vehicle that flies by operating a propeller or a mobility vehicle that travels on the ground by rotating wheels. Furthermore, the delivery mobility vehicle 400 can have a receiving area for the electric cart 100 and deliver the articles, along with the electric cart 100, to the remote destination while moving completely autonomously.

[0064] When the delivery of the articles to the destination is requested, the controller 300 therefore controls the electric trolley 100, which is loaded with the articles, to load the electric trolley 100 into the receiving space in the delivery mobility vehicle 400, and controls the delivery mobility vehicle 400 and moves it to the requested destination.

[0065] This means that when the item to be delivered and the delivery destination are determined, the control unit 300 enables the electric trolley 100, which is loaded with the requested item, to be unloaded from the trolley storage facility 200.

[0066] In the present case, the controller 300 can first sort the electric trolleys 100 that are loaded with the same item, secondarily sort the electric trolleys 100 that are to be moved to the same delivery destination, and manage the respective electric trolleys 100.

[0067] Furthermore, the controller 300 controls the electric cart 100 to load the electric cart 100 into the delivery mobility vehicle 400, which is to be moved to the delivery destination, and controls the delivery mobility vehicle 400 and moves it to the delivery destination, delivering the items.

[0068] In the present case, the controller 300 checks a movement route at the time the delivery mobility vehicle 400 moves to the delivery destination, so that the delivery mobility vehicle 400 can deliver the items sequentially from the local delivery destination to the long-distance delivery destination.

[0069] The article management system, which is structured as described above, uses the electric trolley 100, which can move autonomously, with the articles being managed automatically and easily, and the convenience of the delivery service being ensured through the automation of article delivery.

[0070] Furthermore, the term "control device," such as "controller," "control unit," "control device," or "control module," etc., refers to a hardware device containing a memory and a processor configured to execute one or more steps that are interpreted as an algorithmic structure. The memory stores algorithmic steps, and the processor executes the algorithmic steps to perform one or more processes of a method according to various exemplary embodiments of the present invention.The control device according to exemplary embodiments of the present invention can be implemented by a non-volatile memory configured to store algorithms for controlling an operation of various components of a vehicle or data about software instructions for executing the algorithms, and a processor configured to perform an operation as described above using the data stored in the memory. The memory and the processor can be separate chips. Alternatively, the memory and the processor can be integrated on a single chip. The processor can be implemented as one or more processors. The processor can include various logic circuits and operating circuits, process data according to a program provided by the memory, and generate a control signal according to the processing result.
