Description

[Technical Field]

[0001] The present invention relates to delivery systems. [Background technology]

[0002] For example, products purchased through online shopping are picked up at a logistics center and then transported as deliveries to the delivery center in the area they are responsible for. The deliveries that arrive at the delivery center are loaded onto a cart called a basket cart. The cart with the delivered items is then placed in the cargo compartment of a delivery vehicle, and the deliverer delivers them to individual destinations.

[0003] Efforts have been made to improve the efficiency of collection and delivery for some time. For example, Patent Document 1 discloses a collection and delivery operation management device that includes a progress management unit that displays the progress of collection and delivery work, based on a collection and delivery plan for collection and delivery work formulated for each collection and delivery worker and location information indicating the current location of the collection and delivery worker, on a map showing at least the collection and delivery route determined in the collection and delivery plan and the current location of the collection and delivery worker.

[0004] [Patent Document 1] Patent Publication No. 2021-26445 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, the shortage of delivery personnel has become more pronounced, and it has become necessary to reduce the burden on delivery personnel. For example, the preparation work for delivery, such as loading delivery items onto carts at delivery centers, is a significant burden on delivery personnel, and there is a demand for reducing this burden.

[0006] The present invention has been made in view of the above points, and an object of the present invention is to provide a delivery system that can reduce the burden on the deliverer. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention is a delivery system comprising a sorting unit that sorts deliveries according to the delivery area of ​​a deliverer, a route setting unit that sets a delivery route for each delivery area based on the delivery destination of the deliveries sorted for each delivery area, and a loading unit that loads the deliveries sorted for each delivery area onto a trolley based on the delivery order of the delivery route set for each delivery area.

[0008] According to the present invention configured in this way, deliveries are loaded onto a cart in the order of delivery along the delivery route, so that, for example, a deliverer can depart from a delivery center simply by loading the cart onto a delivery vehicle. Also, when the deliveries arrive at the delivery destination, because the deliveries are loaded onto the cart in the order of delivery along the delivery route, it becomes possible to find the deliveries corresponding to the delivery destination in a shorter time than before. Therefore, the burden on the deliverer can be reduced.

[0009] In the present invention, it is preferable that the delivery items can be loaded onto the cart in multiple layers stacked vertically, and the loading section is configured to load the delivery items that are earlier in the delivery order on the delivery route on the cart in a higher layer than the delivery items that are later in the delivery order.

[0010] According to the present invention configured in this manner, deliveries that are earlier in the delivery order are loaded on the upper level of the cart than deliveries that are later in the delivery order, making it easier for the deliverer to take out the deliveries loaded on the cart when the delivery arrives at the delivery destination.

[0011] In the present invention, preferably, the system further comprises a first storage section and a second storage section capable of storing the deliveries, the sorting section being configured to sort the deliveries for each delivery area and store them in the first storage section provided for each delivery area, the deliveries stored in the first storage section being moved to the second storage section for each delivery area and stored in the second storage section, and the loading section being equipped with a robot arm capable of loading the deliveries stored in the second storage section onto the cart.

[0012] According to the present invention configured in this way, since the robot arm loads the deliveries accumulated in the second storage area onto the cart, it is not necessary to provide a robot arm for each first storage area, for example, which reduces the cost of the delivery system.

[0013] In the present invention, preferably, the second reservoir is disk-shaped and has a slit extending radially from its central portion, the robot arm is located at the inner peripheral end of the slit, and the carriage is located on the outer peripheral side of the robot arm in the slit.

[0014] According to the present invention configured in this manner, the robot arm is positioned at the inner peripheral end of the slit section, and the cart is positioned on the outer peripheral side of the robot arm in the slit section, so it is possible to use the robot arm to load delivery items near the outer peripheral end of the disk-shaped second reservoir section onto the cart while preventing the robot arm from becoming too large.

[0015] In the present invention, the carts are preferably arranged in the slit section in the order of delivery along the delivery route.

[0016] According to the present invention configured in this manner, the trolleys can be loaded onto the delivery vehicle in the same order as they are arranged in the slit section, making it possible for a delivery person, for example, to load the trolleys onto the delivery vehicle easily and in a relatively short time.

[0017] In the present invention, the route setting unit is preferably configured to set a delivery route based on the delivery destination of the delivery item stored in the second storage unit.

[0018] According to the present invention configured in this way, the delivery route is set based on the delivery destination of each delivery item actually stored in the second storage area, which prevents the delivery route from being set in a way that includes delivery items that are not actually loaded onto the cart, thereby improving the accuracy of the delivery route.

[0019] In the present invention, preferably, the delivery system further comprises a limiting unit that limits the total weight of the deliveries stored in the second storage unit to a maximum load capacity of the delivery vehicle.

[0020] According to the present invention configured in this way, the limiting unit limits the total weight of deliveries stored in the second storage unit to a value equal to or less than the maximum load capacity of the delivery vehicle, which prevents a delivery route from being set based on an amount of deliveries that cannot be loaded onto the delivery vehicle, thereby further improving the accuracy of the delivery route.

[0021] In the present invention, preferably, the device further comprises a car navigation device including a display, and the car navigation device is configured to display the delivery route on the display when the delivery person is making a delivery using the delivery vehicle.

[0022] According to the present invention configured in this way, the deliverer can make deliveries while visually checking the delivery route displayed on the display. This eliminates the need for the deliverer to create the delivery route himself, which can eliminate the time required for the deliverer to consider the delivery route before setting out for delivery at the delivery center, for example.

[0023] In the present invention, it is preferable that the car navigation device further includes an exterior image acquisition unit that acquires an exterior image of each delivery item, and that the car navigation device is configured to display the exterior image of the delivery item corresponding to the delivery destination on the display when the delivery vehicle arrives at the delivery destination.

[0024] According to the present invention configured as described above, when the delivery person arrives at the delivery destination, the delivery person can visually grasp the external characteristics of the delivery item corresponding to the delivery destination from the external image displayed on the display, which makes it possible to find the corresponding delivery item from the deliveries loaded on the cart in a shorter time than before. [Effects of the Invention]

[0025] It is possible to provide a delivery system that can reduce the burden on deliverers. [Brief explanation of the drawings]

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the following description of the preferred embodiments is merely exemplary in nature.

[0028] First Embodiment 1 shows a delivery system 1 according to a first embodiment of the present invention. The delivery system 1 includes a delivery center C and a delivery vehicle V (e.g., a truck). The delivery center C and the delivery vehicle V are communicatively connected via a communication network N. The communication network N includes, for example, the Internet, Wi-Fi, a Wi-SUN (Wireless Smart Utility Network), a WAN (Wide Area Network), a LAN (Local Area Network), and the like.

[0029] A distribution center C is set up for each area it covers, and each distribution center C carries out collection and delivery. For convenience, only one distribution center C is shown in FIG. 1.

[0030] For example, products purchased through internet shopping or the like are picked up at a logistics center and then transported as delivery items d to a delivery center C in the delivery area. The delivery items d that arrive at the delivery center C are sorted according to the delivery areas of multiple deliverers. Each deliverer then uses a delivery vehicle (e.g., a truck) to deliver the delivery items d in the delivery area that each deliverer is responsible for to individual delivery destinations (e.g., companies, individual homes, etc.). In other words, the delivery center C serves as a delivery base for the delivery area. In this embodiment, for example, the delivery items d are cardboard boxes containing the products to be delivered.

[0031] As shown in Figure 2, the delivery center C is equipped with a conveyor 2 that transports delivery items d. The conveyor 2 includes a first conveyor section 2a, a second conveyor section 2b, a third conveyor section 2c, a fourth conveyor section 2d, a fifth conveyor section 2e, and a sixth conveyor section 2f. In this embodiment, the direction in which the delivery items d are transported by the conveyor 2 etc. is referred to as the transport direction.

[0032] The deliveries d delivered to the delivery center C are transported by the first conveyor unit 2a, and the first acquisition unit 10 acquires the actual weight and delivery destination of each of the deliveries d.

[0033] The first acquisition unit 10 includes a weight sensor (not shown) capable of measuring the actual weight of the delivery item d, and a scanner (not shown) capable of reading a barcode containing delivery destination information of the delivery item d.

[0034] A first sorting roller 11 is provided downstream of the first conveyor unit 2a in the conveying direction. Therefore, the delivery d that has passed through the first acquisition unit 10 is conveyed to the first sorting roller 11 by the first conveyor unit 2a.

[0035] The first sorting roller 11 sorts the deliveries d into the second conveyor section 2b and the third conveyor section 2c. In this embodiment, deliveries d that are equal to or greater than a first predetermined weight are sorted into the second conveyor section 2b, while deliveries d that are less than the first predetermined weight are sorted into the third conveyor section 2c.

[0036] The deliveries sorted on the second conveyor section 2b are loaded onto another relatively large delivery vehicle (not shown) and delivered to the destination.

[0037] A second sorting roller 12 is provided downstream of the third conveyor section 2c in the conveying direction. Therefore, the delivery d sorted by the third conveyor section 2c is transported to the second sorting roller 12 by the third conveyor section 2c.

[0038] A plurality of pool sections 15 are provided downstream of the second sorting rollers 12 in the conveying direction. The pool sections 15 are provided independently for each delivery area in which the delivery person is responsible for delivery.

[0039] In this embodiment, the pool unit 15 includes a first pool unit 15A, a second pool unit 15B, a third pool unit 15C, and a fourth pool unit 15D. The pool unit 15 is arranged in the order of the first pool unit 15A, the second pool unit 15B, the third pool unit 15C, and the fourth pool unit 15D.

[0040] The first pool unit 15A is configured to store delivery items d whose destinations are in delivery area A, for which deliverer A is responsible for delivery. The second pool unit 15B is configured to store delivery items d whose destinations are in delivery area B, for which deliverer B is responsible for delivery. The third pool unit 15C is configured to store delivery items d whose destinations are in delivery area C, for which deliverer C is responsible for delivery. The fourth pool unit 15D is configured to store delivery items d whose destinations are in delivery area D, for which deliverer D is responsible for delivery. Note that delivery areas A and B, delivery areas B and C, and delivery areas C and D are geographically adjacent areas.

[0041] The second sorting roller 12 has four sorting rollers and is configured to sort the delivery items d into one of the first pool section 15A, the second pool section 15B, the third pool section 15C, and the fourth pool section 15D by controlling the four sorting rollers based on the delivery destination of each delivery item d and the delivery areas A to D. In this embodiment, the second sorting roller 12 is configured to sort the delivery items d whose delivery destination is within delivery area A into the first pool section 15A, sort the delivery items d whose delivery destination is within delivery area B into the second pool section 15B, sort the delivery items d whose delivery destination is within delivery area C into the third pool section 15C, and sort the delivery items d whose delivery destination is within delivery area D into the fourth pool section 15D.

[0042] The first pool section 15A, the second pool section 15B, the third pool section 15C, and the fourth pool section 15D are inclined downward in the conveying direction toward the downstream side (see FIG. 3). As a result, deliveries d sorted by the second sorting roller 12 slide down each pool section 15 toward the downstream side in the conveying direction and are accumulated in the downstream area of ​​each pool section 15 in the conveying direction.

[0043] A fourth conveyor section 2d is provided downstream in the conveying direction of the pool sections 15 (first pool section 15A, second pool section 15B, third pool section 15C, and fourth pool section 15D). An openable and closable gate section 16 is provided between the fourth conveyor section 2d and each pool section 15. As a result, when the gate section 16 is closed, deliveries d are accumulated in the pool sections 15, while when the gate section 16 is open, the deliveries d accumulated in the pool sections 15 slide down onto the fourth conveyor section 2d and are transported by the fourth conveyor section 2d.

[0044] In this embodiment, only one of the four gate sections 16 is in the open state. In other words, one gate section 16 is in the open state, and the remaining three gate sections 16 are in the closed state. As a result, only delivery items d in one of the multiple pool sections 15 (first pool section 15A, second pool section 15B, third pool section 15C, and fourth pool section 15D) are transported by the fourth conveyor section 2d. As an example, FIG. 2 shows that the gate section 16 of the first pool section 15A is in the open state, and the gate sections 16 of the second pool section 15B, third pool section 15C, and fourth pool section 15D are in the closed state, so that delivery items in delivery area A stored in the first pool section 15A are transported by the fourth conveyor section 2d.

[0045] For each delivery d on the fourth conveyor section 2d, the second acquisition section 20 acquires the actual weight, delivery destination, and external appearance image of the delivery d.

[0046] The second acquisition unit 20 is equipped with a weight sensor (not shown) capable of measuring the actual weight of the delivery item d, a scanner (not shown) capable of reading a barcode containing delivery destination information of the delivery item d, and a camera (not shown) capable of acquiring an external image of the delivery item d.

[0047] A third sorting roller 13 is provided downstream of the fourth conveyor unit 2d in the conveying direction. Therefore, the delivery d that has passed through the second acquisition unit 20 is conveyed to the third sorting roller 13 by the fourth conveyor unit 2d.

[0048] The third sorting rollers 13 are configured to sort the delivery item d into the fifth conveyor section 2e and the sixth conveyor section 2f. In this embodiment, the third sorting rollers 13 are configured to sort the delivery item d into the fifth conveyor section 2e if an acquisition error (reading error) of the barcode of the delivery item d occurs in the second acquisition section 20 or if the delivery item d is in a different delivery area. On the other hand, if a detection error (reading error) of the barcode of the delivery item d does not occur in the second acquisition section 20 or if the delivery item d is not in a different delivery area, the delivery item d is sorted into the sixth conveyor section 2f.

[0049] The deliveries d sorted onto the fifth conveyor unit 2e are returned to the first conveyor unit 2a, and the first acquisition unit 10 acquires the actual weight and delivery destination of each deliveries d again.

[0050] The deliveries d sorted on the sixth conveyor section 2f are transported to the roller device 14. A loading plate 30 is provided downstream of the roller device 14 in the transport direction.

[0051] The loading plate 30 has a substantially circular disk shape in a plan view, and is provided with a slit portion 30a extending radially from the center portion thereof.

[0052] Additionally, a plurality of imaging units 31 capable of capturing images of the deliveries d accumulated on the loading plate 30 are provided around the loading plate 30. The plurality of imaging units 31 are arranged so that the entire area of ​​the upper surface of the loading plate 30 is included in the imaging range of the imaging units 31. In this embodiment, four imaging units 31 are installed above the loading plate 30 and are configured to capture images of the entire area of ​​the upper surface of the loading plate 30 from above.

[0053] The loading plate 30 is inclined so that it is positioned lower toward the downstream side in the conveying direction (see FIG. 3). A loading plate robot 32 is provided below the loading plate 30, which can vibrate the loading plate 30 or change the angle of the loading plate 30. The delivery items d conveyed to the loading plate 30 slide down the loading plate 30 due to the vibrations generated by the loading plate robot 32, and are accumulated in the downstream area of ​​the loading plate 30 in the conveying direction. In this embodiment, the roller device 14 changes the angle of the rollers to allow the delivery items d to be accumulated thoroughly on the loading plate 30. Here, the delivery items d on the loading plate 30 may have a portion of a first delivery d overlapping a portion of a second delivery d, as long as the imaging unit 31 can recognize the delivery items d individually. Furthermore, the outer edge of the loading plate 30 is provided with a side wall 30b for preventing the delivery d from falling off the loading plate 30.

[0054] A robot arm 35 is positioned at the inner peripheral end of the slit portion 30a. The tip of the robot arm 35 is provided with a robot hand 36 that can suck and lift up the delivery item d.

[0055] Additionally, a plurality of carts 40 are positioned on the outer periphery of the robot arm 35 in the slit section 30a. The carts 40 are arranged in the order of delivery, and the delivery items d accumulated on the loading plate 30 are loaded onto the carts 40 by the robot arm 35.

[0056] For ease of explanation, numbers are assigned to the carts 40 in Figure 2. The numbers indicate the delivery order based on the delivery route, which will be described later. In this embodiment, the delivery order is from highest to lowest number (8 → 7 → 6 → 5 → 4 → 3 → 2 → 1).

[0057] The cart 40 is, for example, a basket cart (roll box pallet) as shown in FIG. 4. The cart 40 is equipped with casters 41 at the four corners of its lower part. In addition, three double doors 42 are arranged vertically on the front of the cart 40. Each door 42 can be opened and closed independently. Although not shown in FIG. 4, the cart 40 is equipped with a detachable rubber belt (not shown) or rubber band (not shown) for preventing delivery item d from falling off.

[0058] As shown in Fig. 5, an opening 43 is provided at the top of the dolly 40. The robot arm 35 loads the delivery item d onto the dolly 40 through the opening 43. The dolly 40 can be stacked in multiple layers (for example, three layers vertically) to load the delivery item d. In other words, the dolly 40 does not have shelves or the like, and the delivery item d can be loaded by stacking it from the bottom up.

[0059] FIG. 5 shows a state in which delivery item d is loaded onto the dolly 40. For ease of explanation, delivery item d is numbered in FIG. 5. The numbers indicate the delivery order based on the delivery route, which will be described later. In this embodiment, the delivery order is from highest to lowest number (6 → 5 → 4 → 3 → 2 → 1). In this embodiment, delivery item d that is earlier in the delivery order is loaded on the dolly 40 above delivery items d that are later in the delivery order.

[0060] The dollies 40 loaded with the delivery items d are temporarily placed in a space S provided adjacent to the loading plate 30. In the space S, the dollies 40 are lined up in the order of delivery (see FIG. 2).

[0061] In this embodiment, for example, the dolly 40 is moved from the slit portion 30a to the space S by human power. After that, the dolly 40 in the space S is loaded into the luggage compartment L of the delivery vehicle V by, for example, a delivery person (see FIGS. 2 and 3).

[0062] As shown in FIG. 1, the delivery vehicle V is equipped with a vehicle-side communication unit 50 and a car navigation device 51.

[0063] The vehicle-side communication unit 50 is a communication device capable of communicating with the delivery center C via the communication network N, and is connected to the car navigation device 51 so as to be able to send and receive information.

[0064] The car navigation device 51 is mounted on, for example, a delivery vehicle V, and includes a display 52 visible to a delivery person seated in the driver's seat of the delivery vehicle V, a GPS sensor 53 capable of acquiring the current position of the delivery vehicle V, and a navigation control unit 54 connected to the display 52 and the GPS sensor 53. The navigation control unit 54 has a processor (not shown) and a memory unit (not shown). The processor (not shown) is configured to control the display 52 and the like based on a control program stored in the memory unit (not shown).

[0065] 6, the delivery center C includes a center control unit 60. The center control unit 60 is connected to the first acquisition unit 10, the second acquisition unit 20, the imaging unit 31, the map information storage unit 55, and the center-side communication unit 56.

[0066] The first acquisition unit 10 is configured to transmit the acquired actual weight and delivery destination of the delivery item d to the center control unit 60.

[0067] The second acquisition unit 20 is configured to transmit the acquired actual weight, delivery destination, and external appearance image of the delivery item d to the center control unit 60. In addition, the second acquisition unit 20 is configured to transmit error information to the center control unit 60 if an error occurs in acquiring the actual weight, delivery destination, and external appearance image of the delivery item d.

[0068] The imaging unit 31 is configured to transmit an image of the loading plate 30 taken from above to the center control unit 60.

[0069] The map information storage unit 55 stores map information such as road information and building information of the area covered by the delivery center C.

[0070] The center-side communication unit 56 is a communication device capable of communicating with the delivery vehicle V via the communication network N, and is connected to the center control unit 60 so as to be able to send and receive information.

[0071] The center control unit 60 includes a sorting control unit 61 , a route setting unit 62 , a loading control unit 63 , and a restriction unit 64 .

[0072] The sorting control unit 61 is configured to sort the deliveries d that have arrived at the delivery center C according to the delivery areas of the deliverers.

[0073] The route setting unit 62 is configured to set a delivery route for each delivery area based on the delivery destination of the delivery items d sorted for each delivery area.

[0074] The loading control unit 63 is configured to use the robot arm 35 to load onto the trolley 40 delivery items d (delivery items d accumulated on the loading plate 30) sorted for each delivery area based on the delivery order of the delivery route set for each delivery area.

[0075] The limiting unit 64 is configured to limit the amount of delivery items d that can be accumulated on the loading plate 30 to the loadable amount of the delivery vehicle V or less.

[0076] The center control unit 60 also has a processor (not shown) and a memory unit (not shown). The processor (not shown) is configured to control the conveyor 2, the first sorting rollers 11, the second sorting rollers 12, the third sorting rollers 13, the roller device 14, the gate unit 16, the loading plate robot 32, the robot arm 35, the center side communication unit 56, and the like based on a control program stored in the memory unit (not shown).

[0077] Next, the control processing of the delivery system 1 will be described with reference to Figures 7 to 9. The control processing of Figures 7 and 8 is executed by the center control unit 60. The control processing of Figure 9 is executed by the navigation control unit .

[0078] In step S1 of FIG. 7, the center control unit 60 receives from the first acquisition unit 10 the actual weight and delivery destination of the delivery item d on the first conveyor unit 2a.

[0079] In step S2, the center control unit 60 determines whether the actual weight of the delivery d is less than a first predetermined weight (for example, 30 kg). If the determination in step S2 is Yes, the process proceeds to step S3. On the other hand, if the determination in step S2 is No, the process proceeds to step S5.

[0080] In step S3, since the actual weight of the delivery item d to be sorted by the first sorting roller 11 is less than the first predetermined weight (the judgment in step S2 is Yes), the center control unit 60 instructs the first sorting roller 11 to sort it onto the third conveyor unit 2c.

[0081] In step S4, the center control unit 60 (sorting control unit 61) commands the second sorting rollers 12 to sort the delivery item d by delivery area. More specifically, the center control unit 60 commands the four second sorting rollers 12 to sort the delivery item d to the first pool unit 15A when the delivery destination of the delivery item d to be sorted by the first sorting rollers 11 is within delivery area A, to the second pool unit 15B when the delivery destination of the delivery item d is within delivery area B, to the third pool unit 15C when the delivery destination of the delivery item d is within delivery area C, and to the fourth pool unit 15D when the delivery destination of the delivery item d is within delivery area D, and then proceeds to END.

[0082] In step S5, which is executed if the judgment in step S2 is No, since the actual weight of the delivery item d to be sorted by the first sorting roller 11 is equal to or greater than the first predetermined weight, the center control unit 60 instructs the first sorting roller 11 to sort it onto the second conveyor unit 2b and proceeds to the end.

[0083] In this embodiment, the gate unit 16 is closed. As a result, the control process shown in Fig. 7 is repeatedly executed, and deliveries d are accumulated in the pool unit 15 (first pool unit 15A, second pool unit 15B, third pool unit 15C, fourth pool unit 15D) according to the delivery area of ​​the deliverer.

[0084] Next, a description will be given of the control process shown in Fig. 8. The control process shown in Fig. 8 is started when the pool unit 15 has accumulated a predetermined amount or more of deliveries d.

[0085] In step S10, the center control unit 60 issues a command to switch the gate 16 of the pool unit 15 in which a predetermined number of deliveries have accumulated from a closed state to an open state. When the gate changes from a closed state to an open state, the deliveries d accumulated in the pool unit 15 are transported to the fourth conveyor unit 2d. In the example shown in FIG. 2, only the gate 16 of the first pool unit 15A is in an open state, and the gates 16 of the second pool unit 15B, the third pool unit 15C, and the fourth pool unit 15D are in a closed state.

[0086] In step S11, the center control unit 60 receives the actual weight, delivery destination, and external image of the delivery item d on the fourth conveyor unit 2d from the second acquisition unit 20. Also, in step S11, if an error occurs in the second acquisition unit 20 acquiring the actual weight, delivery destination, and external image of the delivery item d, the center control unit 60 receives error information from the second acquisition unit 20.

[0087] In step S12, the center control unit 60 determines whether or not error information has not yet been received from the second acquisition unit 20. If the determination in step S12 is Yes, the process proceeds to step S13. On the other hand, if the determination in step S12 is No, the process proceeds to step S20.

[0088] In step S13, it is determined whether the delivery destination of delivery item d matches the delivery area. If the determination in step S13 is Yes, the process proceeds to step S14. On the other hand, if the determination in step S13 is No, the process proceeds to step S20. In the example shown in Figure 2, step S13 determines whether the delivery destination of delivery item d is within delivery area A.

[0089] In step S14, since the delivery destination and delivery area of ​​the delivery item d to be sorted by the third sorting roller 13 match (the determination in step S12 is Yes), the center control unit 60 commands the third sorting roller 13 to sort the delivery item d to the sixth conveyor unit 2f. The delivery item d sorted to the sixth conveyor unit 2f is accumulated on the loading plate 30.

[0090] In step S15, the center control unit 60 (limiting unit 64) determines whether the actual weight of the delivery item d accumulated on the loading plate 30 is equal to or greater than the second predetermined weight. If the determination in step S15 is Yes, the process proceeds to step S16. On the other hand, if the determination in step S15 is No, the process returns to step S11 and continues. In this embodiment, the second predetermined weight is set to a weight that is a predetermined weight (for example, 30 kg) lighter than the maximum load capacity of the delivery vehicle V.

[0091] In step S16, the center control unit 60 (limiting unit 64) commands the gate unit 16 to switch from the open state to the closed state. This stops the movement (transport) of the delivery items d from the pool unit 15 (for example, the first pool unit 15A) to the loading plate 30, making it possible to limit the total weight of the delivery items d stored on the loading plate 30 to the maximum load capacity of the delivery vehicle V or less.

[0092] In step S17, the center control unit 60 (route setting unit 62) sets a delivery route based on the delivery destinations of all deliveries d stored on the loading plate 30. The delivery route is set using map information stored in the map information storage unit 55. The map information includes road information, including restriction information such as one-way streets, address information, and the like. For example, the delivery route is set by first registering the delivery destinations of each delivery item d on a map. Then, the delivery center C is set as the departure point, and the delivery destination farthest from the delivery center C is set as the destination. The delivery route is then set by connecting nearby points between the delivery center C and each delivery destination so that they pass through roads that the delivery vehicle V can travel. In this embodiment, the delivery route is set so as to minimize the driving distance of the delivery vehicle V.

[0093] In step S18, the center control unit 60 (loading control unit 63) commands the robot arm 35 to load the delivery item d onto the dolly 40 based on the delivery order of the delivery route set in step S17. Note that in step S18, the center control unit 60 (loading control unit 63) commands the robot arm 35 using the image of the delivery item d on the loading plate 30 received from the imaging unit 31.

[0094] In this embodiment, the robot arm 35 loads the delivery items d onto the cart 40 in order of delivery, starting with the latest delivery item d in the delivery order of the delivery route (in the order of 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 shown in FIG. 2). When loading the deliveries d onto the cart 40, the robot arm 35 loads the deliveries d onto the cart 40 in order of delivery, starting with the latest delivery item d to be loaded onto the same cart 40 (in the order of 1 → 2 → 3 → 4 → 5 → 6 shown in FIG. 5). As a result, the delivery items d that are later in the delivery order are loaded lower on the cart 40 than the delivery items d that are earlier in the delivery order; in other words, the delivery items d that are earlier in the delivery order are loaded higher on the cart 40 than the delivery items d that are later in the delivery order.

[0095] In step S19, the center control unit 60 instructs the center-side communication unit 56 to transmit the delivery route set in step S17 and the exterior image of the delivery item d received in step S11 to the delivery vehicle V, and then proceeds to End. Then, the delivery route and the exterior image of the delivery item d are sent from the center-side communication unit 56 to the delivery vehicle V via the communication network N.

[0096] In step S20, which is executed if the judgment in step S12 or step S13 is No, an error has occurred in the second acquisition unit 20 in acquiring the actual weight, delivery destination, and external image of the delivery item d, or the delivery destination and delivery area of ​​the delivery item d to be sorted by the third sorting roller 13 do not match, so the center control unit 60 instructs the third sorting roller 13 to sort it onto the fifth conveyor unit 2e and proceeds to the end.

[0097] In this embodiment, when loading of the delivery items d onto the cart 40 is completed by the control process shown in Fig. 8, the cart 40 loaded with the delivery items d is moved to the space S, for example, manually. The cart 40 is then temporarily placed in the space S. It is preferable that the delivery person completes preparations for placing the cart 40 loaded with the delivery items d in the space S in the delivery order before reporting to the delivery center C.

[0098] When the deliverer arrives at delivery center C early in the morning, he loads the cart 40 in his delivery area, which is placed in space S, into the cargo compartment L of his delivery vehicle V, and then departs from delivery center C. At this time, since the carts 40 are lined up in space S in the order of delivery, the deliverer only needs to load the carts 40 into the cargo compartment L of the delivery vehicle V in the order they were placed in space S. This makes it possible to complete loading of the carts 40 (delivery items d) into the delivery vehicle V in a relatively short time.

[0099] Next, the control process in the navigation control unit 54 of the car navigation device 51 will be described with reference to FIG.

[0100] In step S31, the navigation control unit 54 receives the delivery route and an exterior image of the delivery item d from the delivery center C using the vehicle-side communication unit 50.

[0101] In step S32, the navigation control unit 54 receives the current position of the delivery vehicle V from the GPS sensor 53.

[0102] In step S33, the navigation control unit 54 commands the display 52 to display the delivery route and the current position of the delivery vehicle V. This allows the delivery person to head to the next delivery destination while checking the delivery route by looking at the display 52.

[0103] In step S34, the navigation control unit 54 determines whether the delivery vehicle V has arrived at the delivery destination. If the determination in step S34 is Yes, the process proceeds to step S35. On the other hand, if the determination in step S34 is No, the process returns to step S32.

[0104] In step S35, the navigation control unit 54 commands the display 52 to display an external image of the delivery item d. This allows the deliverer who has arrived at the delivery destination to understand the external characteristics of the delivery item d corresponding to the delivery destination (such as the color and size of the box, any attached stickers, and any printed designs or characters) from the external image of the delivery item d displayed on the display 52. ​​This makes it possible to find the corresponding delivery item d from the cart 40 in the luggage compartment L in a relatively short time.

[0105] In step S36, the navigation control unit 54 receives the current position of the delivery vehicle V from the GPS sensor 53.

[0106] In step S37, the navigation control unit 54 determines whether the delivery vehicle V has departed. If the determination in step S37 is Yes, it is determined that delivery to the delivery destination has been completed, and the process proceeds to step S38. On the other hand, if the determination in step S37 is No, it is determined that delivery to the delivery destination has not been completed, and the process returns to step S35.

[0107] In step S38, the navigation control unit 54 instructs the display 52 to end the display of the exterior image of the delivery item d, since delivery to the delivery destination has been completed.

[0108] In step S39, the navigation control unit 54 determines whether the last arrived delivery destination is the last delivery destination on the delivery route. If the determination in step S39 is Yes, it is determined that delivery of all deliveries d has been completed, and the process proceeds to End. On the other hand, if the determination in step S39 is No, the process returns to step S32.

[0109] As described above, according to this embodiment, the deliveries d are loaded onto the cart 40 in the delivery order of the delivery route, so that, for example, the deliverer can depart from the delivery center C simply by loading the cart 40 onto the delivery vehicle V. Furthermore, even when the deliveries arrive at the delivery destination, the deliveries d are loaded onto the cart 40 in the delivery order of the delivery route, so that the deliveries d corresponding to the delivery destination can be found in a shorter time than before. This reduces the burden on the deliverer.

[0110] In addition, since the delivery item d that is earlier in the delivery order is loaded on the upper level of the cart 40 than the delivery item d that is later in the delivery order, it becomes easier for the deliverer to take out the delivery item d loaded on the cart 40 when it arrives at the delivery destination.

[0111] Furthermore, since the robot arm 35 loads the delivery items d accumulated on the loading plate 30 onto the dolly 40, it is not necessary to provide a robot arm 35 for each pool section 15. This allows the cost of the delivery system 1 to be reduced.

[0112] Furthermore, since the robot arm 35 is positioned at the inner peripheral end of the slit section 30a and the trolley 40 is positioned on the outer peripheral side of the robot arm 35 in the slit section 30a, it is possible to load the delivery item d near the outer peripheral end of the disk-shaped loading plate 30 onto the trolley 40 using the robot arm 35 while preventing the robot arm 35 from becoming larger.

[0113] Furthermore, since the trolleys 40 can be loaded onto the delivery vehicle V in the same order as they are arranged in the slit section 30a, for example, a delivery person can easily load the trolleys 40 onto the delivery vehicle V in a relatively short time.

[0114] Furthermore, since the delivery route is set based on the delivery destination of each delivery item d actually stored on the loading plate 30, it is possible to prevent the delivery route from being set in a manner that includes delivery items d that are not actually loaded onto the dolly 40. This makes it possible to improve the accuracy of the delivery route.

[0115] Furthermore, the limiting unit 64 limits the total weight of the deliveries d stored on the loading plate 30 to the maximum load capacity of the delivery vehicle V, which prevents a delivery route from being set based on an amount of deliveries that cannot be loaded onto the delivery vehicle V. This makes it possible to further improve the accuracy of the delivery route.

[0116] Furthermore, the deliverer can make deliveries while visually checking the delivery route displayed on the display 52. ​​This eliminates the need for the deliverer to create a delivery route by himself, which can eliminate the time required for the deliverer to consider the delivery route before setting out for delivery at the delivery center C, for example.

[0117] Furthermore, when the deliverer arrives at the delivery destination, the deliverer can visually grasp the external characteristics of the delivery item d corresponding to the delivery destination from the external image displayed on the display 52. ​​This allows the work of finding the corresponding delivery item d from among the deliveries d loaded on the dolly 40 to be completed in a shorter time than before.

[0118] Second Embodiment Next, a delivery system 1 according to a second embodiment of the present invention will be described with reference to Fig. 10. In the second embodiment, differences from the first embodiment will be mainly described. The delivery system 1 according to the second embodiment is provided in a delivery center C that is larger in scale than the first embodiment (for example, with a wider coverage area or a larger delivery volume). Also, although the first acquisition unit 10, the second acquisition unit 20, etc. are not shown in Fig. 10, the center control unit 60 can receive each piece of acquired information from the first acquisition unit 10, the second acquisition unit 20, etc., also in the second embodiment.

[0119] As shown in Fig. 10, in the delivery center C, a plurality of pool sections 15 are arranged in two rows. A pool section 15 is provided for each delivery area of ​​a deliverer. Unlike the first embodiment, this embodiment does not include a loading plate 30.

[0120] Between one row of pool sections 15 and the other row of pool sections 15, conveyors 2 and sorting rollers 17 are alternately arranged in a line.

[0121] Furthermore, between the conveyor 2 and the sorting rollers 17 and the pool section 15, a gate section 16 that can be freely opened and closed is provided for each pool section 15.

[0122] Furthermore, on the opposite side of the plurality of pool sections 15 to the conveyor 2, a rail section R is provided that extends along the direction in which the plurality of pool sections 15 are arranged side by side.

[0123] A robot arm 35 is set on the rail portion R. The robot arm 35 is movable on the rail portion R along the direction in which the plurality of pool portions 15 are arranged side by side.

[0124] The imaging section 31 is set so that its imaging range can capture images of at least the entire area of ​​the plurality of pool sections 15 .

[0125] In this embodiment, the delivery system 1 is configured to transport deliveries d that have arrived at the delivery center C using a conveyor 2, and to sort the deliveries d according to the delivery areas of the deliverers using sorting rollers 17, and store them in the corresponding pools 15. At this time, all gates 16 are in the open state.

[0126] When a predetermined number of deliveries d accumulate in a predetermined pool section 15, the gate section 16 of the predetermined pool section 15 is switched from an open state to a closed state. In this embodiment, when the gate section 16 is closed, deliveries d whose destinations are within the delivery area of ​​the predetermined pool section 15 are circulated by the conveyor 2. When all deliveries d in the predetermined pool section 15 are loaded onto the cart 40 and the gate section 16 is switched from a closed state to an open state, the deliveries d are sorted into the predetermined pool section 15 by the sorting rollers 17.

[0127] After the gate 16 of a predetermined pool 15 is switched from an open state to a closed state, a delivery route is set based on the delivery destinations of the deliveries d stored in the predetermined pool 15. In other words, a delivery route is set for each delivery area based on the delivery destinations of the deliveries d sorted for each delivery area. The robot arm 35 is then configured to load the deliveries d stored in the predetermined pool 15 onto the carts 40 placed in the space S based on the delivery order of the set delivery route. Here, the carts 40 are arranged in the delivery order of the delivery route, so the deliverer only needs to load the carts 40 into the cargo compartment L of the delivery vehicle V in the order in which they are arranged in the space S, allowing the carts 40 to be loaded onto the delivery vehicle V in a relatively short time.

[0128] In this embodiment, rails R are provided along the direction in which the multiple pool sections 15 are arranged side by side, and the robot arm 35 is configured to be able to move freely along the direction in which the multiple pool sections 15 are arranged on the rails R. This eliminates the need to provide a robot arm 35 for each pool section 15, thereby achieving cost reduction.

[0129] <<Variation>> In the first and second embodiments, an example is described in which the product or the like to be delivered as delivery item d is contained in a cardboard box, but it may also be placed in a packing material or wrapping material other than a cardboard box.

[0130] In addition, in embodiments 1 and 2, the first acquisition unit 10 and the second acquisition unit 20 have been described as examples of reading a barcode containing delivery destination information of the delivery item d, but they may also be configured to read a two-dimensional barcode, an IC tag, etc.

[0131] In addition, in the first and second embodiments, the first sorting roller 11 sorts deliveries d having a first predetermined weight or more to the second conveyor section 2b, while sorting deliveries d having a weight less than the first predetermined weight to the third conveyor section 2c. However, sorting may be performed according to the size of the deliveries d acquired by the first acquisition section 10. For example, deliveries d may be classified into three categories, "large," "medium," and "small," according to their size, and the first sorting roller 11 may sort "large" deliveries d and "small" deliveries d to the second conveyor section 2b, and "medium" deliveries d to the third conveyor section 2c.

[0132] Furthermore, in the first and second embodiments, an example of sorting delivery item d using the first sorting roller 11, the second sorting roller 12, the third sorting roller 13 and the sorting roller 17 has been described, but delivery item d may also be sorted using, for example, a slide shoe type, cross belt type, pop-up type, turntable type, pusher type, diverter type or tilt tray type sorter (sorting means), or a robot type sorter (sorting means).

[0133] Furthermore, in the first and second embodiments, a plurality of pool sections 15 are arranged side by side, but the pool sections 15 may be arranged at positions spaced apart from one another.

[0134] In addition, in the first embodiment, the loading plate 30 has a substantially circular shape in a plan view and includes the slit portion 30a extending radially from the center portion thereof, but may have a shape other than a substantially circular shape in a plan view (for example, a rectangular shape in a plan view), or may not include the slit portion 30a. When the loading plate 30 does not include the slit portion 30a, the robot arm 35 and the dolly 40 are arranged around the loading plate 30.

[0135] In addition, in embodiment 1, only delivery items d from one delivery area (e.g., delivery area A) were allowed to accumulate on the loading plate 30, but if the delivery items d from one delivery area (e.g., delivery area A) accumulated in one pool section 15 (e.g., first pool section 15A) alone are significantly less than the maximum loading capacity of the delivery vehicle V, the delivery area may be changed (e.g., two or more delivery areas may be combined into one, or the delivery area may be expanded) so that some of the delivery items d accumulated in another pool section 15 (e.g., second pool section 15B) can be accumulated on the loading plate 30 and delivered by the delivery vehicle V. On the other hand, if the amount of deliveries d in one delivery area (e.g., delivery area A) stored in one pool section 15 (e.g., first pool section 15A) greatly exceeds the maximum load capacity of the delivery vehicle V, the delivery area may be changed (e.g., reduced to the delivery area) so that the amount of deliveries d exceeding the maximum load capacity of the delivery vehicle V can be stored on the loading plate 30 together with deliveries d stored in other pool sections 15 (e.g., second pool section 15B), and delivered by the delivery vehicle V. In this way, it is possible to reduce the variation in the amount of deliveries d for each delivery vehicle V and prevent the burden from being concentrated on certain deliverers.

[0136] Furthermore, in the first embodiment, an example has been described in which the control process shown in FIG. 8 is started when a predetermined amount or more of deliveries d have accumulated in the pool section 15. However, if a predetermined amount or more of deliveries d have not accumulated in one pool section 15 (e.g., the first pool section 15A) even after a predetermined time (e.g., 6 hours, 12 hours, 24 hours, etc.) has elapsed, the delivery area may be changed (e.g., four delivery areas may be combined into one), so that the deliveries d accumulated in multiple pool sections 15 (e.g., the first pool section 15A, the second pool section 15B, the third pool section 15C, and the fourth pool section 15D) are accumulated on the loading plate 30 and delivered by the delivery vehicle V. By doing so, even if the amount of deliveries d accumulated in each pool section 15 is significantly below the maximum loading capacity of the delivery vehicle V due to traffic conditions or the like, the deliveries d in multiple pool sections 15 are loaded onto the delivery vehicle V and delivered, so it is possible to prevent deliveries d from accumulating in the pool section 15 for a relatively long period of time. Therefore, it is possible to prevent delays in delivering the delivery item d to the delivery destination.

[0137] Furthermore, in the first and second embodiments, the robot arm 35 has been described as loading the trolley 40 in order of delivery along the delivery route, starting with the latest item. However, the robot arm 35 may be configured to load the trolley 40 in order of delivery along the delivery route, starting with the earliest item.

[0138] Furthermore, in the first and second embodiments, the robot arm 35 has been described as loading the deliveries d onto the same cart 40 in order of delivery order, starting with the latest one. However, the deliveries d may be loaded onto the cart 40 in order of delivery order, starting with the earliest one along the delivery route.

[0139] In addition, in the first and second embodiments, an example has been described in which the delivery route is set so as to minimize the travel distance of the delivery vehicle V, but the delivery route may be set taking into consideration factors other than travel distance. For example, for a delivery item d for which a delivery time slot has been specified, the delivery route may be set so that the delivery vehicle V arrives at the delivery destination of the delivery item d during the specified delivery time slot.

[0140] In addition, in the first and second embodiments, an example has been described in which the delivery center C is set as the starting point of the delivery route and the delivery destination farthest from the delivery center C is set as the destination, but the starting point and destination may be set at any location. For example, by setting the delivery center C as the starting point and destination of the delivery route, the delivery route may be set in a loop shape, starting from the delivery center C, passing through each delivery destination, and then ending at the delivery center C.

[0141] Furthermore, in the first and second embodiments, the delivery route does not take into consideration redelivery of the delivery item d, but redelivery may be taken into consideration. For example, if the delivery destination (e.g., a private residence) is not home when the deliverer arrives, and there is a request for redelivery from the delivery destination, the delivery route may be modified based on the content of the request (e.g., a specified redelivery time slot, etc.).

[0142] Furthermore, in the second embodiment, when the gate 16 of a predetermined pool section 15 is closed, the delivery item d whose destination is within the delivery area of ​​the predetermined pool section 15 is circulated by the conveyor 2. However, by providing multiple pool sections 15 for each delivery area, at least one pool section 15 whose gate 16 is open may be provided for each delivery area. For example, when one pool section 15 and another pool section 15 corresponding to a predetermined delivery area are provided, even if the gate 16 of one pool section 15 is closed, the gate 16 of the other pool section 15 may be opened, so that the sorting roller 17 sorts the delivery item d whose destination is within the predetermined delivery area into the other pool section 15.

[0143] In addition, in embodiments 1 and 2, an example has been described in which a delivery route is displayed on the display 52 of the car navigation device 51, but the delivery route may be output as audio from a speaker (not shown), or both the display 52 and a speaker (not shown) may be used.

[0144] Furthermore, in embodiments 1 and 2, an example was described in which the car navigation device 51 is installed in the delivery vehicle V, but it may also be a portable car navigation device (not shown) or a portable terminal (e.g., a smartphone, an electronic device that can be attached to and detached from the cart 40).

[0145] Furthermore, in the first and second embodiments, the delivery system 1 is described as being equipped with a car navigation device 51. However, the delivery system 1 does not necessarily have to be equipped with a car navigation device 51. In other words, the car navigation device 51 is not an essential component of the delivery system 1. If the delivery system 1 is not equipped with a car navigation device 51, a paper with a delivery route printed on it using an output device (e.g., a printer) not shown may be handed to the deliverer. This makes it possible to provide a delivery system 1 that uses not only a delivery vehicle V equipped with a car navigation device 51, but also a delivery vehicle (not shown) that does not have a car navigation device 51. Furthermore, if the deliverer is familiar with the delivery area for which he or she is responsible and can deliver the delivery item d by checking the delivery destination of the delivery item d loaded in delivery order on the dolly 40 before departing for the next delivery destination, the paper with the delivery route printed on it is not necessary, and therefore the output device (not shown) described above is not an essential component of the delivery system 1.

[0146] Furthermore, in the first and second embodiments, the example of the delivery center C has been described, but it may be a sales office (not shown) or the like as long as it is a delivery base in the area in charge.

[0147] Furthermore, in embodiment 1, an example was described in which the movement of the trolley 40 from the slit section 30a to the space S and the loading of the trolley 40 from the space S into the delivery vehicle V were performed manually, and in embodiment 2, an example was described in which the loading of the trolley 40 from the space S into the delivery vehicle V was performed manually (by the delivery person), but the movement of the trolley 40 into the space S and the loading of the trolley 40 into the delivery vehicle V may also be performed by means other than manual power (for example, a loading machine, a transport robot, etc.).
