[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6902308 Summary of the Invention [Problem to be solved by the invention]

[0004] If one considers attaching a hook to the end of a wire lowered from an unmanned aircraft and hanging luggage on the hook, Patent Document 1 does not describe automatically receiving luggage hung on the hook.

[0005] Therefore, an object of the present disclosure is to provide a luggage receiving box and luggage receiving system for an unmanned aircraft that can automatically receive luggage hung on a hook at the end of a wire that is lowered from the unmanned aircraft, and that can prevent the received luggage from being exposed to rain and wind. [Means for solving the problem]

[0006] The baggage receiving box for an unmanned aerial vehicle of the present disclosure includes: A load receiving unit that receives a load carried by the unmanned aerial vehicle and tilts to move the load in an oblique direction based on the gravity of the load; a main body that forms a space covered from above and that receives the luggage moving from the luggage receiving section and that forms an outlet for the luggage; A damping device for slowing down the speed of the tilting movement of the load receiver; Equipped with.

[0007] According to the baggage receiving box of the present disclosure, the baggage receiving section tilts as baggage is placed on the receiving section from the unmanned aerial vehicle. The damping device reduces the speed of the tilting movement of the baggage receiving section, so the descent speed of the hook accompanying the lowering of the wire is greater than the movement speed of the baggage receiving section. This allows the baggage to be removed from the hook when the baggage receiving section tilts. The baggage that has been removed from the hook moves from the baggage receiving section to the space within the main body, the upper part of which is covered, as the baggage receiving section tilts. This prevents the baggage from being exposed to the elements.

[0008] The space is defined as an outlet side space, the main body has an opening that opens upward, and forms an entrance space through the opening to receive the luggage held by a wire that is lowered from the unmanned aerial vehicle; The inlet side space and the outlet side space are electrically connected to each other, The cargo receiving section may be provided in the inlet side space.

[0009] According to this, the cargo receiving section is provided in the entrance side space (inside the opening) of the main body, so that the cargo can be easily placed on the cargo receiving section by placing the wire and the cargo held by it into the opening.

[0010] The package receiving box of the present disclosure may include a return force applying unit that returns the package receiving section to its pre-tilt state. With this, after the package receiving section is tilted and the package is moved from the package receiving section, the package receiving section can be automatically returned to its pre-tilt state. This makes it possible to receive another package.

[0011] The package receiving box of the present disclosure may include a stopper portion for stopping the package in front of the outlet. This can prevent the package from unintentionally coming out of the outlet and store the package inside the main body.

[0012] The package receiving box of the present disclosure may include a wire guide portion that is provided above the opening and receives the wire from a horizontal direction while guiding the wire to the opening, thereby making it easier to insert the wire and the package held by it into the opening.

[0013] The load receiving portion and the bottom surface of the main body may include a through-hole for passing rainwater to the rear side, thereby making it possible to prevent rainwater from accumulating in the load receiving portion and the main body.

[0014] The package receiving box of the present disclosure may include a rotating body provided on at least one of the package receiving portion and the bottom surface portion of the main body for moving the package toward the outlet. This allows the package to be moved toward the outlet, making it easier to take out the package from the outlet.

[0015] The baggage receiving system disclosed herein includes an unmanned aerial vehicle that carries baggage, A baggage receiving box is provided. The baggage receiving box is A luggage receiving section that receives the luggage from the unmanned aerial vehicle and tilts to move the luggage in an oblique direction based on the gravity of the luggage; a main body that forms a space covered from above and that receives the luggage moving from the luggage receiving section and that forms an outlet for the luggage; A damping device for slowing down the speed of the tilting movement of the load receiving portion, The unmanned airplane lowers a wire having a hook at its tip, on which the luggage is hung, above the luggage receiving section, The hook is configured to disengage from the load when the load is placed on the load receiving portion and the load receiving portion tilts under the damping action of the damping device.

[0016] This can provide the same effects as those of the above-mentioned parcel receiving box. [Brief description of the drawings]

[0018] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 shows the configuration of a delivery box 2 of a parcel receiving system 1 of this embodiment. The parcel receiving system 1 includes the delivery box 2 and an unmanned aerial vehicle 40 (also called a drone) (see Fig. 4).

[0019] (Configuration of delivery box) The delivery box 2 is a parcel receiving box for an unmanned aerial vehicle that receives and stores parcels 200 carried by the unmanned aerial vehicle 40. The delivery box 2 (main body 3 described below) is attached to, for example, the underside of the eaves portion 102 of the building 100 by a fixing portion 27 described below, and is arranged so as to hang down in the space below the eaves portion 102 (i.e., under the eaves). The building 100 is, for example, a detached house, but may also be an apartment building or a business office. The eaves portion 102 is formed above the windows 103 of the building 100 in a shape that protrudes outward beyond the exterior wall 104 on which the windows 103 are provided. The eaves portion 102 is an eaves that constitutes part of the roof 101 of the building 100.

[0020] Delivery box 2 may be attached to a part of building 100 other than eaves portion 102 (for example, exterior wall 104). If an eaves portion is attached above window 103 in addition to eaves 102, delivery box 2 may be attached to that eaves portion. In the case of an apartment building, the ceiling portion of the balcony (the floor portion of the balcony on the floor above) may serve as the eaves portion, and delivery box 2 may be attached to that ceiling portion.

[0021] The delivery box 2 includes a main body 3, a door unit 12, a package receiving unit 20, a damper 22 (see FIG. 2), a spring 23 (see FIG. 2), a weight member 24, conveying units 25 and 26, a fixing unit 27, and a wire guiding unit 30. Note that FIG. 1 illustrates a cross section of the main body 3 and shows how a package 200 is received by the delivery box 2 (main body 3).

[0022] (Main body configuration) The main body 3 is formed in a box shape with an opening 5 that opens upward and a luggage removal opening 11 that is horizontally shifted from the opening 5 and lower than the opening 5. The opening 5 is an entrance for receiving luggage 200. The opening 5 is located, for example, outside the eaves 102. The opening 5 is formed, for example, in a right-angled quadrangle in a plan view (see FIG. 3), but may be formed in another shape (for example, a circle).

[0023] The outlet 11 is provided in a position facing the window 103 in the space below the eaves portion 102 (under-the-eaves space). The distance between the outlet 11 (in other words, the door portion 12 described below) and the window 103 is set to a distance such that, for example, when the window 103 is closed and an attempt is made to take out the luggage 200 from the outlet 11, the luggage 200 interferes with the window 103 and the luggage 200 cannot be taken out. The distance may be, for example, greater than 0 cm and less than or equal to 30 cm. The window 103 may be a window on a high floor (a floor above the second floor) of the building 100 (for example, the top floor), or it may be a window on the first floor.

[0024] Within the main body 3, there are formed baggage receiving spaces 6, 10 that guide the baggage 200 from the opening 5 to the removal opening 11. In detail, the main body 3 has a baggage receiving section 4 and a baggage storage section 9. The baggage receiving section 4 forms an entrance side space 6 inside thereof that receives the baggage 200 suspended from a wire 44 of the unmanned airplane 40 via the opening 5. The entrance side space 6 is a space within the main body 3 that faces the opening 5. The entrance side space 6 is formed to a size that allows the entire baggage 200 placed on the baggage receiving section 20 to fit within the entrance side space 6.

[0025] The luggage receiving section 4 (entrance space 6) has a side section 7 that surrounds the entire lateral periphery of the entrance space 6, and a bottom section 8. Of the side section 7, a wall surface 7a located opposite the luggage storage section 9 is formed as an inclined surface that gradually displaces toward the luggage storage section 9 as it extends downward. As a result, the horizontal width of the entrance space 6 gradually decreases as it extends downward. The inclined surface 7a functions as a stopper that prevents a weight member 24, which will be described later, from falling in the opposite direction to the direction P (see FIG. 1) of the tilting operation of the luggage receiving section 20.

[0026] The bottom surface 8 of the luggage receiving section 4 is formed in an inclined shape that gradually displaces downward toward the space 10 in the luggage storage section 9. The inclination angle of the bottom surface 8 with respect to the horizontal plane may be set to the same angle as the inclination angle of the bottom surface 14 of the luggage storage section 9 with respect to the horizontal plane. The bottom surface 8 functions as a stopper that stops the tilting movement of the luggage receiving section 20. In addition, the bottom surface 8 functions as a guide surface that guides luggage 200 that moves from the luggage receiving section 20 as the luggage receiving section 20 tilts, into the space 10 in the luggage storage section 9.

[0027] The bottom surface portion 8 may be formed with through-holes 8a penetrating between the surface of the bottom surface portion 8 facing the space 6 (inner surface) and the surface on the opposite side (outer surface). The through-holes 8a may be formed in a plurality of locations. With this, even if rainwater seeps into the space 6 from the opening 5, the rainwater can be discharged to the outside through the through-holes 8a, and the rainwater can be prevented from flowing into the space 10 of the luggage storage section 9. The bottom surface portion 8 may be formed, for example, in a mesh shape with a large number of through-holes 8a arranged vertically and horizontally.

[0028] The luggage storage section 9 forms an exit side space 10 (luggage storage space) inside thereof for receiving and storing luggage 200 moving from the luggage receiving section 20, and also forms an outlet 11 which is an opening of the exit side space 10. The exit side space 10 is connected to the entrance side space 6. The entrance side space 6 and the exit side space 10 form a luggage guide space for guiding luggage 200 from the opening 5 to the outlet 11. The exit side space 10 changes direction from the entrance side space 6 and extends in a direction approaching the window 103. The exit side space 10 also extends from the entrance side space 6 in a direction at an angle to the horizontal and vertical directions (i.e., diagonally). The exit side space 10 is a space within the main body 3 that does not face the opening 5 (a space whose upper part is covered).

[0029] The exit side space 10 is covered with walls at the top, bottom and sides. That is, the luggage storage section 9 has an upper surface section 13 that covers the top of the space 10, a bottom surface section 14 that covers the bottom of the space 10, and a side surface section (not shown) that covers the side of the space 10. The bottom surface section 14 is formed in an inclined shape that gradually displaces downward as it approaches the take-out opening 11. The bottom surface section 14 functions as a conveying section that conveys the luggage 200 from the luggage receiving section 20 toward the take-out opening 11 together with a rotating body 26 described later. The inclination angle of the bottom surface sections 8, 14 of the main body 3 with respect to the horizontal plane is, for example, 5° or more and 45° or less. By making it 5° or more, it is possible to easily move the luggage 200 toward the take-out opening 11. By making it 45° or less, it is possible to suppress the luggage 200 from gaining too much momentum when the luggage 200 moves, and to suppress damage to the luggage 200.

[0030] In the example of Fig. 1, the entire area of ​​the bottom surface portions 8, 14 is formed to be inclined, but a part of it may be formed to be inclined and the remaining part (for example, the part immediately before the outlet 11) may be formed to be a horizontal surface. In the example of Fig. 1, the bottom surface portions 8, 14 are formed to be inclined flat surfaces, but they may be formed to be curved surfaces.

[0031] The bottom surface 14 of the luggage storage section 10 may be formed with through-holes 14a that allow rainwater to pass through to the back surface (outer surface) side, similar to the bottom surface 8 of the luggage receiving section 4. The through-holes 14a may be formed in multiple locations. The bottom surface 14 may be formed, for example, in a mesh shape with a large number of through-holes 14a arranged vertically and horizontally. Note that a groove is formed in the bottom surface 14 for providing the rotor 26 as a conveying section, and by forming the groove in a penetrating shape that penetrates through to the back surface side, the gap between the groove and the rotor 26 that fits therein may serve as the through-hole 14a for allowing rainwater to pass through.

[0032] The exit side space 10 may be formed to have a length that allows the simultaneous storage of a plurality of luggage 200. In this case, the width L of the exit side space 10 in the arrangement direction of the luggage 200 (the direction in which the luggage 200 moves) may be set to be equal to or greater than the width of two pieces of luggage 200, for example, 80 cm or greater.

[0033] (Door section configuration) The door unit 12 is an opening / closing unit that opens and closes the take-out opening 11. The door unit 12 is provided to face the window 103. The door unit 12 is, for example, a pivoting door, and is provided in a form that interferes with the window 103 and cannot be opened when an attempt is made to open the door unit 12 while the window 103 is closed. The door unit 12 functions as a luggage stopper unit that stops luggage 200 moving from the luggage receiving unit 20 from exiting the take-out opening 11. A lock may be provided on the door unit 12 to prevent theft of the luggage 200. When the distance between the take-out opening 11 and the door unit 12 and the window 103 is narrow (when the luggage 200 cannot be taken out while the window 103 is closed), a lock may not be provided on the door unit 12.

[0034] (Configuration of the cargo receiving section) The load receiving section 20 is provided in the entrance side space 6 at a position facing the opening 5 above. The load receiving section 20 is a portion on which the load 200 carried by the unmanned aerial vehicle 40 is placed, in other words, a portion that receives the underside of the load 200 suspended from the unmanned aerial vehicle 40. The load receiving section 20 is formed, for example, in a plate shape, and is provided so that the surface of the load receiving section 20 faces the opening 5. When no load 200 is placed on the load receiving section 20 (when the load receiving section 20 is in a horizontal state), the distance between the surface (load receiving surface) of the load receiving section 20 and the opening 5 is, for example, greater than the height of the load 200, specifically, for example, 30 cm or more.

[0035] The load receiving section 20 is provided so as to be rotatable around a rotation shaft 21 oriented horizontally. However, the load receiving section 20 cannot rotate without limit, and the rotation range is limited by the bottom surface 8 of the load receiving section 4, the inclined side surface 7a, and a weight member 24 described below. The rotation shaft 21 is oriented in a direction perpendicular to the plane of the paper in FIG. 1. The rotation shaft 21 is supported by the main body 3.

[0036] When no luggage 200 is placed on the luggage receiving section 20, the surface of the luggage receiving section 20 is held horizontal. When luggage 200 is placed on the luggage receiving section 20, the luggage receiving section 20 rotates around the rotation axis 21 based on the gravity of the luggage 200, and tilts so as to move the luggage 200 toward the exit side space 10 (take-out opening 11). The operation of the luggage receiving section 20 (tilting operation and return operation) is controlled by the gravity of the luggage 200, a damper 22 (see FIG. 2), a spring 23 (see FIG. 2), and a weight member 24, and no electric member such as a motor, an engine, pneumatic or hydraulic member, etc. are provided.

[0037] The load receiving section 20 may be formed with a through-hole 20a penetrating between its front and back surfaces. The through-holes 20a may be formed in a plurality of locations. This allows rainwater to pass through the through-holes 20a and exit to the back surface of the load receiving section 20, thereby preventing rainwater from accumulating on the front surface of the load receiving section 20. The load receiving section 20 may be formed, for example, in a mesh shape with a large number of through-holes 20a arranged vertically and horizontally. Note that the load receiving section 20 is formed with a groove for providing the rotor 25 as a conveying section, and by forming the groove in a penetrating shape penetrating the back surface, the gap between the groove and the rotor 25 fitted therein may be used as the through-hole 20a for passing rainwater.

[0038] (Damper configuration) The damper 22 (see FIG. 2) as a damping device is a member that slows down the speed of the tilting and returning movements of the load receiving section 20. The damper 22 is a resistance applying section that applies resistance in the direction opposite to the movement direction of the load receiving section 20. For example, the damper 22 applies viscous resistance to the load receiving section 20 by a viscous substance such as oil in conjunction with the movement of the load receiving section 20. The damper 22 may be, for example, a rotary damper that is provided on the rotating shaft 21 and applies resistance in the direction around the rotating shaft 21. In this case, the damper 22 constitutes a part of the rotating shaft 21.

[0039] In addition to or in place of the rotary damper 22, another type of damper, for example, a telescopic damper that moves in a linear direction, may be applied to the load receiving section 20. In this case, the telescopic damper may be provided between the rear surface of the load receiving section 20 and the bottom surface section 8, or on the front surface side of the load receiving section 20.

[0040] (Spring configuration) The spring 23 (see FIG. 2) is an elastic member that biases the load receiving portion 20 in the direction opposite to the tilting rotation direction P (see FIG. 1) of the load receiving portion 20. In other words, the spring 23 is a return force imparting portion that imparts to the load receiving portion 20 a force that returns the load receiving portion 20 to its original horizontal state after the load receiving portion 20 has been tilted. The spring 23, together with a weight member 24 described below, is also a holding force imparting portion that imparts to the load receiving portion 20 a force that keeps the load receiving portion 20 in a horizontal state.

[0041] The spring 23 is, for example, a torsion spring provided on the rotating shaft 21. The spring 23 may be provided on the side of the rotating shaft 21 opposite to the side on which the damper 22 is provided (example of FIG. 2), or may be provided on the same side as the damper 22. The spring 23 may also be integral with the damper 22.

[0042] The spring 23 may have a spring constant (spring force) that is weak enough that, for example, if the weight member 24 is removed, the load receiving portion 20 cannot be held horizontally when no load 200 is placed on the load receiving portion 20.

[0043] (Configuration of weight members) The weight member 24 has a common rotation axis 21 with the load receiving section 20, and is provided so as to rotate about the rotation axis 21 in conjunction with the operation of the load receiving section 20 while maintaining a positional relationship with the load receiving section 20. In other words, the angle between the weight member 24 and the load receiving section 20 is maintained constant before rotation, during rotation, and throughout the rotation. The angle is greater than 90° and less than 180°.

[0044] The weight member 24 is a holding force imparting part that imparts a force to the load receiving part 20 to keep the load receiving part 20 in a horizontal state. The weight member 24 is also a returning force imparting part that imparts, together with the spring 23, a force to the load receiving part 20 to return the load receiving part 20 to its original horizontal state after the load receiving part 20 has been tilted. In other words, the weight member 24 is a moment imparting part that imparts a moment to the rotating shaft 21 around the rotating shaft 21 in the opposite direction to the tilting movement direction P of the load receiving part 20.

[0045] The weight of the weight member 24, in other words, the moment acting on the rotating shaft 21 by the weight member 24, may be determined to a weight (moment) such that, for example, if the spring 23 were not present, the load receiving section 20 would not be able to be held in a horizontal state when no load 200 is placed on the load receiving section 20. In this way, the load receiving section 20 is held in a horizontal state by cooperation between the weight member 24 and the spring 23, and the weight of the weight member 24 and the spring force of the spring 23 may be determined so that, if either the weight member 24 or the spring 23 is missing, the load receiving section 20 cannot be held in a horizontal state.

[0046] The weight of the weight member 24 may be determined so as not to press the inclined side surface portion 7a of the main body 3 in the opposite direction to the inclination rotation direction P, except when the load receiving portion 20 returns to its original horizontal position after the tilting operation. In this case, the moment in the opposite direction to the inclination rotation direction P due to the weight member 24 and the spring 23 is balanced with the moment in the inclination rotation direction P due to the weight of the load receiving portion 20. In this case, even if the inclined side surface portion 7a is removed, the load receiving portion 20 is maintained in a horizontal state when no load 200 is placed on the load receiving portion 20. The weight of the weight member 24 may be determined so as to press the side surface portion 7a in the opposite direction to the inclination rotation direction P.

[0047] 1, when the load receiving section 20 is divided into two regions along a virtual line L0 extending in the up-down direction (vertical direction) and intersecting the rotation axis 21, the weight member 24 is provided in the region opposite to the region in which the load receiving section 20 is provided. More specifically, the weight member 24 is, for example, plate-shaped, and is provided in a state in which the load receiving section 20 is inclined in the opposite direction to the tilt rotation direction P of the load receiving section 20 when no load 200 is placed on the load receiving section 20. The weight member 24 comes into contact with the inclined side surface portion 7a when the load receiving section 20 is returned to the horizontal position, thereby preventing the weight member 24 from excessively inclining in the opposite direction to the tilt rotation direction P.

[0048] The weight member 24 may rotate in association with the tilting of the load receiving section 20, but may not exceed the imaginary line L0 in Fig. 1. That is, the weight member 24 may rotate in association with the tilting of the load receiving section 20 to a position overlapping with the imaginary line L0 (i.e., to stand up vertically), or may rotate within an area on the opposite side of the imaginary line L0 where the load receiving section 20 is provided. In this way, the weight member 24 does not assume a forward tilting position (a position tilted toward the load receiving section 20) even after rotation, which makes it easier to return the load receiving section 20 to its original horizontal position.

[0049] (Conveyor section configuration) The conveying units 25, 26 include a first conveying unit 25 provided in the load receiving unit 20 and a second conveying unit 26 provided in the bottom portions 8, 14 of the main body 3. These conveying units 25, 26 are rotating bodies (in other words, rollers) that are rotatable about an axis that is oriented in a direction perpendicular to the paper surface of FIG.

[0050] The first rotor 25 is provided to move the luggage 200 toward the exit-side space 10 as the luggage receiving section 20 tilts. A plurality of first rotors 25 may be provided along the movement direction of the luggage 200. The second rotor 26 is provided to move the luggage 200 from the luggage receiving section 20 toward the take-out opening 11. A plurality of second rotors 26 may be provided on the bottom surface 14 of the exit-side space 10 along the movement direction of the luggage 200. The rotors 25, 26 are non-electric members, and rotate based on frictional force with the luggage 200. In other words, no electric member (motor, etc.) is provided to rotate the rotors 25, 26.

[0051] When the load receiving portion 10 and the bottom portions 8 and 14 are made of materials with low friction (for example, static and dynamic friction coefficients of 0.2 or less), the rotors 25 and 26 do not need to be provided.

[0052] (Fixed part configuration) The fixing portion 27 is a member for fixing the delivery box 2 to the structure 100. A plurality of fixing portions 27 may be provided. The fixing portion 27 includes an attachment portion 28 that is attached to the structure 100, and a connection portion 29 that connects the attachment portion 28 and the main body 3. The attachment portion 28 is attached, for example, to the rear surface of the eaves portion 102 with a bolt or the like. The connection portion 29 is formed in a shape (for example, a rod shape) that extends downward from the attachment portion 28. One end of the connection portion 29 is fixed to the attachment portion 28, and the other end is fixed, for example, to the upper surface portion 13 of the main body 3.

[0053] (Configuration of wire guide section) The wire guide unit 30 is a part that is provided above the opening 5 and that guides the wire 44 and the luggage 200 held by it, which are lowered from the unmanned airplane 40, toward the center of the opening 5. In other words, the wire guide unit 30 is a wire swing suppression unit that suppresses the wire 44 and the luggage 200 from swinging horizontally due to the wind above the opening 5. The wire guide unit 30 has a guide main body unit 31 that guides the wire 44 toward the center of the opening 5 as the wire 44 moves horizontally above the opening 5, and a support unit 32 that supports the guide main body unit 31.

[0054] As shown in FIG. 3, the guide body 31 is a V-shaped portion (V-guide) formed in a V-shape in a plan view. The guide body 31 is formed in a line-symmetrical shape in the plan view of FIG. 3. More specifically, the V-shaped portion 31 as the guide body has a pair of linear portions 31a, 31b each extending in a straight line. These linear portions 31a, 31b are formed in a symmetrical shape with respect to a line symmetrical axis L1 extending horizontally in the plan view. One end 31c, 31d of the linear portions 31a, 31b is a free end, and the other end 31e constitutes a common end portion of the linear portions 31a, 31b. This common end 31e is connected to the support portion 32. The linear portions 31a, 31b are composed of a solid rod-shaped member or a hollow rod-shaped member (pipe member).

[0055] When a virtual line L2 (see FIG. 3) extending horizontally and passing through the center O of the opening 5 is defined as the opening center line, the axis of line symmetry L1 of the guide body 31 coincides with the opening center line L2 when viewed in the plan view of FIG. 3. When a direction from one end 31c, 31d of the linear portions 31a, 31b toward the other end 31e is defined as a wire guiding direction, the guide body 31 gradually approaches the opening center line L2 as it proceeds in the wire guiding direction.

[0056] Between the pair of linear portions 31a, 31b, a wire receiving area that horizontally receives the wire 44 is formed. The wire receiving area is an area in which a part of the outer periphery (between ends 31c, 31d of linear portions 31a, 31b) is open and the remaining part is closed by linear portions 31a, 31b.

[0057] The linear portions 31a and 31b (wire receiving area) overlap with the area inside the opening 5 in the plan view of FIG. 3. More specifically, the common end 31e of the linear portions 31a and 31b is located on the opening center line L2, and the free ends 31c and 31d are located outside the opening 5. The free ends 31c and 31d are located outside the opening 5 in the direction X along which the opening center line L2 or the axis of linear symmetry L1 extends, and are also located outside the opening 5 in the direction Y perpendicular to the direction X. The common end 31e is located near the edge of the opening 5 in the plan view, but may be located inside the opening 5. The width between the free ends 31c and 31d (the width of the entrance of the wire receiving area) is larger than the width of the opening 5 in the direction Y. The distance in direction Y between linear portions 31a, 31b (the width of the wire receiving area in direction Y) gradually decreases from the entrance of the wire receiving area toward the back side (the common end 31e side). In addition, the area of ​​the overlapping area between the wire receiving area and opening 5 is smaller than the area of ​​opening 5 in a plan view.

[0058] 1, the guide body 31 is slightly inclined with respect to the horizontal line so as to gradually displace downward from the free ends 31c, 31d toward the common end 31e (from the entrance of the wire receiving area toward the back side). In other words, the free ends 31c, 31d are located above the common end 31e. The inclination angle of one linear portion 31a and the inclination angle of the other linear portion 31b with respect to the horizontal line are the same.

[0059] 1, the guide body 31 may be located outside the eaves portion 102 in the horizontal direction (on the side away from the building 100). The guide body 31 may also be located above the tip 102a of the eaves portion 102. This can prevent the wire 44 and the baggage 200 from hitting the building 100.

[0060] Also, the horizontal receiving direction of the wire 44 into the wire receiving area (the direction from the entrance of the wire receiving area toward the back side) is, for example, a direction approaching the building 100, but may be another direction (a direction along the exterior wall 104, or a direction away from the building 100). In other words, the direction X (see FIG. 3) of the linear symmetry axis L1 of the guide main body 31 is a direction perpendicular to the exterior wall 104 or the window 103, but may be another direction (a direction along the exterior wall 104 or the window 103, or a direction obliquely intersecting the exterior wall 104 or the window 103).

[0061] The support portion 32 has one end connected to the guide main body portion 31 and the other end connected to the main body 3 (for example, the side surface portion 7 of the baggage receiving portion 4). The support portion 32 may be, for example, a linear member (a solid rod-shaped member or a hollow rod-shaped member) extending linearly.

[0062] (Unmanned aircraft configuration) The unmanned airplane 40 shown in Fig. 4 is an unmanned airplane for logistics (carrying luggage). The unmanned airplane 40 comprises an aircraft body 41, multiple arms 42 connected to the aircraft body 41, and propellers 43 as lift generating units connected to each arm 42. The unmanned airplane 40 further comprises a wire 44, a hook 45 provided at the tip of the wire 44, and a wire lifting unit 46 (winch) that lowers and raises the wire 44.

[0063] As shown in Figs. 5 and 6, the baggage 200 is hooked onto the hook 45. The baggage 200 has a packaging section 201 for packaging the contents, and a hooking section 202 for hooking onto the hook 45. The packaging section 201 is formed in a box shape. The packaging section 201 has an inclined section 204 at its upper portion. The inclined section 204 is gradually displaced outward in the width direction of the packaging section 201 as it extends downward. The inclined section 204 is formed on both sides of the hooking section 202 when viewed from the side in Fig. 6. The hooking section 202 is located at the upper end of the inclined section 204. The hooking section 202 has a hole 203 formed therein that penetrates in the horizontal direction for hooking the hook 45.

[0064] The hook 45 is configured to come off the luggage 200 when the luggage receiving section 20 and the luggage 200 placed thereon tilt while being damped by the damper 22. More specifically, the hook 45 is a weight that moves vertically at a speed faster than the tilting speed of the luggage receiving section 20 as the wire 44 descends when the luggage receiving section 20 tilts. The hook 45 is formed with a hook 47 for hanging the hook 202 of the luggage 200. The hook 47 is formed in a shape that protrudes upward from the lower part of the hook 45, and forms a recess 48 on the inside that is open at the top. The upper part 202a (the part above the hole 203) of the hook 202 of the luggage 200 is inserted into the recess 48.

[0065] Moreover, the hook 45 has an inclined surface 49 facing the recessed portion 48 and the hooking portion 47 above the recessed portion 48 and the hooking portion 47. The inclined surface 49 is gradually displaced upward from the recessed portion 48 toward the hooking portion 47 (to the left of the paper surface of FIG. 6). A gap is formed between the inclined surface 49 and the upper end of the hooking portion 47. The vertical width d1 of the gap is larger than the vertical width of the upper portion 202a of the hooking portion 202 of the baggage 200. That is, the upper portion 202a can be inserted into or removed from the recessed portion 48 through the gap of the vertical width d1. Moreover, when the upper portion 202a is inserted into the recessed portion 48, a first gap is formed between the upper end 202b of the hooking portion 202 (upper portion 202a) and the inclined surface 49.

[0066] As shown in FIG. 6, the lower surface of the hook 45 includes an inclined surface 50. The inclined surface 50 is inclined in the same inclination direction as the inclined surface 49 described above, and specifically, it is gradually displaced to the left of the paper surface of FIG. 6 as it goes upward. The width d2 from the upper end of the inclined surface 50 to the upper end of the hook portion 47 is smaller than the vertical width of the hole 203. That is, the hook portion 47 can be inserted into the hole 203 and removed from the hole 203. In addition, when the upper portion 202a is inserted into the recess 48, a second gap is formed between the inclined surface 50 and the lower edge 203a of the hole 203. The second gap and the first gap may be set to the same vertical width. That is, when the hook 45 is lowered relative to the luggage 200 and the lower edge 203a of the hole 203 comes into contact with the inclined surface 50, the upper end 202b of the hook portion 202 and the inclined surface 49 may also come into contact with each other.

[0067] The hook 45 is hooked to the hook portion 202 by the first gap and the second gap so as to be movable downward relatively to the hook portion 202 of the luggage 200. The inclined surfaces 49 and 50 are portions that allow the hook 45 to move obliquely downward.

[0068] Wire lifting unit 46 shown in FIG. 4 is provided in machine body 41, and includes a winding unit that winds up wire 44, and a drive unit (motor or the like) that rotationally drives the winding unit.

[0069] As shown in FIG. 7, the unmanned airplane 40 further includes a communication unit 51, a memory unit 52, various sensors 53, and a control unit 59. The communication unit 51 performs wireless communication with a control device provided at the facility of the delivery company of the package 200. If a communication device is provided on the delivery box 2 side (the delivery box 2 itself or in the vicinity of the delivery box 2 (for example, within the building 100)), the communication unit 51 may include a communication unit that communicates with that communication device. The memory unit 52 stores various data necessary for controlling the unmanned airplane 40.

[0070] The sensor 53 acquires various data necessary for controlling the unmanned airplane 40. Specifically, the sensor 53 may include, for example, a current position sensor 54 (such as a GPS sensor) that detects the current position of the unmanned airplane 40, a heading direction sensor 55 (such as a geomagnetic sensor) that detects the heading direction of the unmanned airplane 40, an altitude sensor 56 that detects the altitude of the unmanned airplane 40, an imaging unit (camera) 57 that captures the view below the unmanned airplane 40, a luggage sensor 58 that detects that the luggage 200 has been released from the hook 45, and the like. The luggage sensor 58 may be, for example, a load sensor that detects the load applied to the wire 44.

[0071] (Handling drones, functioning of delivery boxes) The control unit 59 controls the unmanned airplane 40. FIG. 8 illustrates an example of the process executed by the control unit 59. The process of FIG. 8 and the operation of the delivery box 2 will be described below. When the process of FIG. 8 is started, the control unit 59 drives and controls the propeller 43 so as to fly the unmanned airplane 40 to a location (the location of the building 100, the vicinity of the delivery box 2) where the delivery box 2 to which the package 200 is to be delivered is installed (S1). The control unit 59 may control the flight of the unmanned airplane 40 based on, for example, location data of the delivery box 2 or the building 100 stored in advance in the storage unit 52 and current position data of the unmanned airplane 40 detected by the current position sensor 54. Alternatively, the control unit 59 may receive a remote control signal transmitted from the delivery company side via the communication unit 51 and control the flight of the unmanned airplane 40 based on the received remote control signal. The unmanned airplane 40 flies with the package 200 hooked on the hook 45 suspended from the aircraft body 41 or stored in the aircraft body 41. In addition, when the unmanned aircraft 40 reaches the location of the building 100, the control unit 59 determines the position of the delivery box 2 based on, for example, an image captured by the photographing unit 57, and causes the unmanned aircraft 40 to hover in front of the delivery box 2.

[0072] Next, the control unit 59 drives the wire lifting unit 46 to slightly lower the wire 44 and the luggage 200 (S2). The amount of descent of the luggage 200 at this time is determined so that the luggage 200 is located between the guide main body 31 and the opening 5 in the up-down direction (hereinafter referred to as the intermediate position). The control unit 59 may determine the intermediate position based on an image captured by the photographing unit 57, for example. Then, the control unit 59 determines the amount of descent of the wire 44 and the luggage 200 based on the altitude of the unmanned airplane 40 detected by the altitude sensor 56 and the intermediate position.

[0073] Alternatively, data indicating a combination of the altitude of the unmanned airplane 40 and the amount of descent of the wire 44 (luggage 200) that positions the luggage 200 at the intermediate position is stored in advance in the memory unit 52. The control unit 59 may then control the unmanned airplane 40 to reach the altitude stored in the memory unit 52, and also control the descent of the wire 44 to reach the amount of descent stored in the memory unit 52.

[0074] Next, the control unit 59 controls the drive of the propeller 43 so as to move the unmanned airplane 40 to a position directly above the opening 5 (S3). At this time, the control unit 59 determines the shape of the guidance main body 31 based on, for example, an image captured by the image capture unit 57, and determines the horizontal direction in which the unmanned airplane 40 can enter the inner area (wire receiving area) of the guidance main body 31 based on the shape. The control unit 59 moves the unmanned airplane 40 to a position directly above the opening 5 while moving in the above-mentioned direction in which the unmanned airplane 40 can enter, and causes the unmanned airplane 40 to hover at the position directly above the opening 5. The control unit 59 may determine the position directly above the opening 5 based on, for example, an image captured by the image capture unit 57.

[0075] The travel direction of the unmanned airplane 40 when it is moved to a position directly above the opening 5 (the direction in which it can enter the wire receiving area) may be stored in advance in the memory unit 52. Alternatively, the control unit 59 may transmit an image captured by the imaging unit 57 to the delivery company, receive a remote control signal from the delivery company based on the image via the communication unit 51, and control the flight of the unmanned airplane 40 based on the received remote control signal. Alternatively, the control unit 59 may receive a guidance signal from the delivery box 2, and control the flight of the unmanned airplane 40 based on the received guidance signal.

[0076] Next, the control unit 59 drives the wire lifting unit 46 to lower the wire 44 and the luggage 200, and places the luggage 200 on the luggage receiving unit 20 (S4).

[0077] When the cargo 200 is placed on the cargo receiving section 20, the cargo receiving section 20 tilts based on the gravity of the cargo 200. At this time, the tilting speed of the cargo receiving section 20 is suppressed by the action of the damper 22, so that the descent speed of the hook 45 accompanying the descent of the wire 44 is greater than the movement speed of the cargo receiving section 20 and the cargo 200 placed thereon. As a result, the hook 45 moves downward relative to the hanging section 202 of the cargo 200. Then, the inclined surface 49 of the hook 45 comes into contact with the upper end 202b of the hanging section 202, and the inclined surface 50 of the hook 45 comes into contact with the lower edge 203a of the hole 203. Then, as the hook 45 descends, the hanging section 202 slides on the inclined surfaces 49 and 50, so that the hook 45 also moves horizontally. That is, the hook 45 moves diagonally downward. As a result, the hook 45 comes out of the hole 203 (see FIG. 9). In addition, the hook 45 that has been released from the hole 203 may slide on the inclined portion 204 of the luggage 200.

[0078] The luggage 200, from which the hook 45 has been released, moves from the luggage receiving section 20 to the exit side space 10 as the luggage receiving section 20 tilts and the rotating body 25 rotates. Then, the luggage 200 moves toward the outlet 11 as the rotating body 26 rotates. The luggage 200 then hits the door section 12 and stops.

[0079] After the cargo 200 has been moved, the load receiving section 20 returns to its original horizontal position under the action of the spring 23 and the weight member 24. At this time, the speed of the returning movement of the load receiving section 20 is suppressed by the action of the damper 22. In addition, the returning movement of the load receiving section 20 is stopped by the contact between the weight member 24 and the inclined side surface portion 7a of the main body 3.

[0080] On the other hand, when the control unit 59 of the unmanned airplane 40 determines based on the baggage sensor 58 that the hook 45 and the baggage 200 have been detached, it drives the wire lifting unit 46 to raise the wire 44 and the hook 45 (S5). Thereafter, the control unit 59 causes the unmanned airplane 40 to return.

[0081] (effect) The effects of this embodiment will be described below. According to this embodiment, the package 200 suspended from the wire 44 can be automatically received by the delivery box 2 without cutting the wire 44. Since the package 200 is detached from the hook 45 inside the main body 3 (inside the opening 5), it is possible to prevent the package 200 or the hook 45 from being blown away by the wind while the hook 45 is being detached. This makes it easier to detach the hook 45 from the package 200. In addition, it is possible to prevent the package 200 detached from the hook 45 from being blown away by the wind.

[0082] Since the luggage 200 is stored in the luggage storage section 9, which is covered from above and sides, the luggage 200 is prevented from being exposed to the elements. Furthermore, the luggage storage section 9 makes it possible for the delivered luggage 200 to be hidden from view from the outside, thereby preventing theft of the luggage 200. Furthermore, since the removal opening 11 is provided in a position facing the window 103, the window 103 can be opened and the luggage 200 can be removed from within the building 100. Furthermore, since the luggage 200 cannot be removed unless the window 103 is opened, theft of the luggage 200 can be prevented, and crime prevention can be improved.

[0083] The wire guide section 30 can prevent the wire 44 and the luggage 200 from being significantly swung by the wind above the opening 5. This makes it easier to put the luggage 200 into the opening 5. In a plan view, the axis of symmetry L1 of the guide body section 31 coincides with the opening center line L2, so the wire 44 and the luggage 200 can be guided toward the center of the opening 5. This can prevent the luggage 200 from hitting the edge of the opening 5.

[0084] Since the width of the entrance of the inner region of the guide main body 31 is larger than the width of the opening 5, the wire 44 can be easily inserted into the inner region. Since the guide main body 31 is inclined so as to be displaced downward as it proceeds toward the back of the inner region, the wire 44 can be guided (regulated) at a lower position as it proceeds toward the back. In other words, as the wire 44 and the luggage 200 are guided toward the center of the opening 5, the swing width of the wire 44 and the luggage 200 due to the wind can be reduced. Also, since the entrance of the inner region of the guide main body 31 is located above the back side of the inner region, the wire 44 can be easily inserted into the inner region even if the wire 44 and the luggage 200 are slightly swayed by the wind.

[0085] Since the wire guiding section 30 is composed of a linear member, the weight and cost of the delivery box 2 (wire guiding section 30) can be reduced.

[0086] The weight member 24 allows the selection of a spring 23 with a small spring constant. This allows the load receiving section 20 to be tilted even when the load 200 is light.

[0087] Since the delivery box 2 is fixed to the eaves portion 102, major modifications to the building 100 can be avoided, and the initial cost of installing the delivery box 2 can be reduced.

[0088] (Variation 1) The present disclosure is not limited to the above embodiment and various modifications are possible. For example, the wire guide unit may be configured as shown in Figs. 10 and 11. In Figs. 10 and 11, the same components as those in the above embodiment are denoted by the same reference numerals. The wire guide unit 70 in Figs. 10 and 11 is a portion that is provided above the opening 5 and guides the wire 44 and the luggage 200 to the center of the opening 5. The wire guide unit 70 has a guide body 71 that guides the wire 44 and the luggage 200 to the center of the opening 5, and a support 75 that supports the guide body 71. The guide body 71 and the support 75 are configured from linear members (solid rod-shaped members or hollow rod-shaped members).

[0089] The guide body 71 is formed in a symmetrical shape with respect to a horizontally extending axis of symmetry L3 in the plan view of FIG. 11. The axis of symmetry L3 coincides with the center line L2 of the opening. The guide body 71 forms a wire receiving area inside thereof that receives the wire 44 from the horizontal direction. The wire receiving area includes a gradually narrowing area that gradually narrows in width in the direction Y perpendicular to the axis of symmetry L3 from the entrance of the wire receiving area toward the back side, and a rectangular area that is located further back than the gradually narrowing area and has a constant width in the direction Y. The gradually narrowing area and the rectangular area are electrically connected. The guide body 71 has a gradually narrowing portion 72 that forms the gradually narrowing area, and rectangular portions 73 and 74 that form the rectangular area.

[0090] The gradually narrowing portion 72 is composed of a pair of linear members symmetrical about the axis of linear symmetry L3. The space between the ends 72a, 72a of the pair of linear members 72 is the entrance of the wire receiving area. The end 72a is located outside the opening 5 in the direction X and outside the opening 5 in the direction Y when viewed from above in FIG. 11. The width between the ends 72a, 72a (the entrance width of the wire receiving area) is larger than the width of the opening 5 in the direction Y. The other end 72b of the gradually narrowing portion 72 is connected to the square portions 73, 74. The other end 72b is located inside the opening 5 when viewed from above.

[0091] The square portions 73 and 74 have a parallel portion 73 composed of a pair of linear members parallel to each other, and a connecting portion 74 which is a linear member connecting the ends of the parallel portion 73. The connecting portion 74 is located on the side of the center O of the opening 5 in the direction X1 from the entrance of the wire receiving area toward the back side, as viewed in the plan view of FIG. 11. As viewed in the plan view of FIG. 11, the area of ​​the square region formed by the square portions 73 and 74 is smaller than the area of ​​the opening 5. That is, the width of the square portions 73 and 74 in the direction X is smaller than the width of the opening 5 in the direction X. The width of the square portions 73 and 74 in the direction Y is smaller than the width of the opening 5 in the direction Y. In this way, as viewed in the plan view, the entire square portions 73 and 74 are located inside the opening 5. Also, as viewed in the plan view, the center of the square region may coincide with the center O of the opening 5.

[0092] As shown in Fig. 10, the guide body portion 71 is slightly inclined with respect to the horizontal line so as to gradually displace downward from the entrance of the wire receiving area toward the back side. The inclination angle of the gradually narrowing portion 72 and the inclination angle of the parallel portion 73 may be the same. The inclination angles of the pair of linear members constituting the gradually narrowing portion 72 are the same. The inclination angles of the pair of linear members constituting the parallel portion 73 are the same.

[0093] The support portion 75 has a vertical extension portion 75a extending in the vertical direction, and a connection portion 75b that connects an upper end of the vertical extension portion 75a to an intermediate portion of the connection portion 74 of the guide main body portion 71. The lower end of the vertical extension portion 75a is connected to the main body 3. The connection portion 75b is formed so as to bend in the horizontal direction from the vertical extension portion 75a. When viewed from the top in FIG. 11, the connection portion 75b is located inside the opening 5 and overlaps with the axis of symmetry L3 and the opening center line L1.

[0094] In step S3 of Fig. 8, control unit 59 (see Fig. 7) of unmanned airplane 40 controls unmanned airplane 40 to move wire 44 from the horizontal direction into the gradually narrowing area formed by gradually narrowing portion 72, and then into the rectangular area formed by rectangular portions 73 and 74. That is, control unit 59 moves unmanned airplane 40 to a position directly above the rectangular area.

[0095] In this way, according to the first modification, it is possible to obtain the same effect as the above embodiment. In addition, the rectangular area of ​​the guide main body 71 makes it easy to determine the target position for hovering when the unmanned airplane 40 is moved to a position directly above the opening 5 and hovered there. Since the area of ​​the rectangular area is smaller than the area of ​​the opening 5, it is easy to insert the baggage 200 into the opening 5 by placing the wire 44 in the rectangular area.

[0096] (Other variations) The wire guide units 30, 70 do not have to be provided. In this case, step S2 in Fig. 8 may be omitted. That is, the control unit 59 of the unmanned airplane 40 does not lower the wire 44 and the cargo 200 until the unmanned airplane 40 reaches a position directly above the opening 5. The control unit 59 lowers the wire 44 and the cargo 200 when the unmanned airplane 40 reaches a position directly above the opening 5.

[0097] The delivery box 2 may be provided such that the main body 3 penetrates the outer wall 104 of the building 100, and the baggage outlet 11 is located inside the building 100. When the baggage outlet 11 is located inside the building 100, the door unit 12 does not need to be provided.

[0098] Delivery box 2 does not have to be attached to building 100, and may be provided, for example, within the site (garden) on which building 100 is located, on a gatepost, or the like.

[0099] Instead of the door portion 12, a stopper portion that stops the luggage 200 in front of the luggage outlet 11 in the main body 3 and does not block the entire outlet 11, or a stopper portion that does not open or close, may be provided.

[0100] The opening 5 of the main body 3 may not be provided, and the load receiving portion 20 may be provided so as to be exposed to the outside space.

[0101] In the above embodiment, the load receiving portion 20 is automatically returned to its original position, but it may be returned to its original position manually. In this case, the spring 23 for returning the load receiving portion 20 may not be provided.

[0102] In the above embodiment, an example is shown in which the load receiving portion 20 is returned to or maintained in a horizontal state by the cooperative action of the spring 23 and the weight member 24, but the load receiving portion 20 may be returned to or maintained in a horizontal state by only one of the spring 23 and the weight member 24.

[0103] In the above embodiment, the wire guide units 30, 70 made of linear members are exemplified, but wire guide units made of plate-shaped members may also be used. In this case, the plate-shaped member of the wire guide unit may be configured to form a wire receiving area in which a part of the periphery of the space above the opening 5 is open and the remaining part is closed. Furthermore, the plate-shaped member of the wire guide unit may be provided so as to have a planar shape similar to the planar shape of the wire guide units 30, 70 (planar shapes shown in Figs. 3 and 11). This can further suppress the swaying of the wire 44 and the luggage 200 due to wind.

[0104] The guide body of the wire guide may have a shape other than the above-mentioned guide body 31, 71. For example, the guide body may be U-shaped in plan view. The rectangular portions 73, 74 in FIG. 11 may have a U-shaped plan view. [Explanation of symbols]
