Description

[Technical field]

[0001] The present invention relates to a logistics system. [Background technology]

[0002] Conventionally, in cargo storage facilities such as logistics warehouses, cargo pick-up operations could not be performed outside the warehouse's business hours, such as at night, and trucks that arrived during those hours had to wait until the opening time of business. This situation resulted in long working hours for truck drivers and was inefficient. In recent years, therefore, efforts have been made to improve the efficiency of work by automatically removing and loading cargo from the truck bed using unmanned cargo pick-up and transport devices such as unmanned forklifts. In order to perform this unmanned operation, it is necessary to position the truck at the desired cargo pick-up stop position.

[0003] As a method for positioning the truck, a method is adopted in which position information such as images of the truck stopped at the loading stop position detected by a sensor or camera installed on the building side is obtained, and for example, the truck driver fine-tunes the position of the truck while looking at the detected images. Alternatively, a method is also known in which the position and attitude of the truck is detected, and the detection data is received by the unmanned loading and transporting device, so that the unmanned loading and transporting device recognizes the position of the truck and moves accordingly.

[0004] An example of an apparatus for detecting a stopping position of a vehicle using a sensor or the like and controlling the position of the vehicle is shown in Patent Document 1. Patent document 1 describes a device that, when the front and rear wheels of a vehicle are placed on a first front and rear wheel conveyor installed in the storage berth, drives the front and rear wheel conveyor and a second front and rear wheel conveyor installed in the storage lift to move the vehicle laterally from the storage berth to the storage lift.The device sends a distance detection signal from a lateral movement distance measuring device to a control device, and when the vehicle reaches the center of the storage lift, the control device sends a stop signal to the drive motors of each conveyor, stopping each of these conveyors and positioning the vehicle in the center of the storage lift.

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 7-10289 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the conventional vehicle position adjustment method as shown in Patent Document 1, it is necessary to install multiple sensors and cameras on the building side to acquire the vehicle's position information. Therefore, the installation and maintenance of the sensors and cameras requires a lot of time and effort, and furthermore, the cost of the parts for the sensors and cameras, the control system for the detected position information, etc. is high, which causes a problem of increasing the cost of the entire logistics system.

[0007] In addition, even if the vehicle position information is acquired by a sensor or a camera, the truck driver needs to use the position information to adjust the stopping position so that the vehicle is at the desired stopping position. Therefore, the time required to adjust the stopping position varies depending on the driver's driving skill, and in some cases, it may be necessary to repeatedly acquire the position information and adjust the stopping position, so there is a problem that the stopping position cannot be adjusted easily in a short time and without being affected by the driver's skill. Therefore, there is a demand for efficiency improvement of the entire logistics system, including automatic unloading and loading of luggage from and to vehicles, and there is room for improvement in this regard.

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a logistics system that can position a vehicle at a cargo unloading stop position easily and quickly, and can improve the efficiency of the entire system, including automatically unloading and loading cargo onto the vehicle. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the logistics system of the present invention is a logistics system equipped in a luggage storage facility with a vehicle loading stop position adjustment device for positioning the loading stop position of a vehicle at which luggage can be automatically removed and loaded by an unmanned luggage transport device, the luggage storage facility comprising a luggage storage space for storing the luggage, and a loading stop space having the loading stop position, the loading stop position adjustment device comprising a rear wheel positioning unit formed at a position lower than the floor surface of the body of the loading stop space and guiding the vehicle in the backward direction to position the rear wheels of the vehicle at the loading stop position, and a front wheel positioning unit provided on the body, on which the front wheels of the vehicle with their rear wheels positioned in the rear wheel positioning unit are placed and which can move in the left-right direction perpendicular to the direction of travel of the vehicle, and the unmanned luggage transport device automatically transports the luggage between the luggage storage space and the loading stop position of the vehicle of the unmanned luggage transport device positioned at the loading stop position of the loading stop space.

[0010] In the logistics system according to the present invention, when unloading and loading onto the vehicle bed, the vehicle is moved backwards and the rear wheels are guided to a rear wheel positioning section formed at a position lower than the floor surface of the vehicle body, thereby positioning the rear wheels in the front-rear and left-right directions. In the rear wheel positioning section, the part on which the front wheels are placed can be moved left-right, so the left-right position of the front wheels can be adjusted. This makes it possible to easily and quickly position the vehicle at the loading stop position with the left-right positions of the rear and front wheels of the vehicle aligned by the loading stop position adjustment device with a simple configuration.

[0011] In this way, the present invention allows a vehicle to be accurately positioned at the loading stop position, and therefore allows the unmanned loading and transporting device to efficiently transport luggage between the luggage storage space and the loading platform of a vehicle positioned at the loading stop position of the loading stop space in an unmanned manner. This reduces the burden of manual loading work, and allows loading work to be performed at any time, such as at night, in luggage storage facilities such as logistics warehouses.

[0012] In addition, with the present invention, the cargo unloading stop position adjustment device can be installed in advance on the structure side of the building, eliminating the need to install expensive sensors or cameras, and also eliminating the need for maintenance of these and positioning control, thereby enabling a reduction in equipment costs for adjusting the vehicle stop position.

[0013] In the logistics system according to the present invention, it is preferable that the unmanned article pick-up and transport device is capable of automatically picking up and loading articles from both the left and right sides of a loading platform of the vehicle.

[0014] In this case, the unmanned cargo-handling and transporting device can be placed close to both the left and right sides of the vehicle's loading platform, allowing cargo to be unloaded and loaded from both sides of the vehicle, thereby improving work efficiency.

[0015] In addition, it is preferable that the logistics system of the present invention is characterized in that the unmanned luggage pick-up and transport device comprises a first transport device that moves within the luggage storage space and a second transport device that moves within the luggage pick-up stop space, and that the luggage is handed over between the first transport device and the second transport device.

[0016] In this case, even if there is a step in the floor between the luggage storage space and the luggage unloading stop space, a first conveying device and a second conveying device dedicated to each space are provided, and luggage can be efficiently handed over between the first conveying device and the second conveying device in an unmanned manner.

[0017] In addition, it is preferable that the logistics system of the present invention has a stopping position detection unit that detects that the vehicle has been positioned at the cargo unloading stopping position, and when the detection information is detected by the stopping position detection unit, the unmanned cargo unloading and transport device automatically starts the operation of removing and loading cargo onto the loading platform of the vehicle.

[0018] With this configuration, when the stopping position detection unit detects detection information when unloading luggage from the luggage bed of the vehicle, control can be performed to start the operation of automatically unloading luggage from the luggage bed of the vehicle in the luggage unloading stop space by the unmanned luggage unloading and transporting device.On the other hand, when the stopping position detection unit detects detection information when loading luggage from the luggage storage space onto the luggage bed of the vehicle, control can be performed to start the operation of loading luggage onto the luggage bed of the vehicle. Effect of the Invention

[0019] According to the logistics system of the present invention, a vehicle can be positioned at a cargo unloading stop position easily and quickly, and the efficiency of the entire system can be improved, including automatic unloading and loading of cargo onto the vehicle.

[Figure 7] FIG. 7 is a cross-sectional view taken along the line III-III shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, a logistics system according to an embodiment of the present invention will be described with reference to the drawings.

[0022] Fig. 1 shows the overall configuration of a logistics system 100 according to the present embodiment, and is a plan view of a logistics warehouse 2 equipped with a goods pick-up stop position adjustment device 1. Fig. 2 is a cross-sectional view taken along line II shown in Fig. 1, and is a cross-sectional view of the logistics system. 1 and 2, an article pick-up stop position adjustment device 1 provided in a logistics system 100 of this embodiment is applied to a logistics warehouse 2, which is a baggage storage facility. The article pick-up stop position adjustment device 1 is a device for positioning a loading platform 31 of a truck 3 (vehicle) at an article pick-up stop position T where an unmanned article pick-up conveying device 4 can automatically pick up and load an article M onto the loading platform 31 of the truck 3 (vehicle).

[0023] The logistics warehouse 2 includes a luggage storage space 21 for storing luggage M, and a luggage pick-up stop space 20 having a luggage pick-up stop position adjustment device 1. The logistics warehouse 2 includes a floor structure 22. Reference numeral 23 shown in Figs. 1 and 2 denotes a column provided integrally with the floor structure 22.

[0024] The baggage storage space 21 is arranged on the left side of the paper in Figures 1 and 2 in the logistics warehouse 2. Multiple baggage pick-up stop spaces 20 (three in this case) are provided. The baggage pick-up stop spaces 20 are arranged adjacent to the right side of the baggage storage space 21 in Figures 1 and 2 in the logistics warehouse 2. The multiple baggage pick-up stop spaces 20 (20A, 20B, 20C) are arranged in the vertical direction of the paper in Figure 1.

[0025] 1 is the front-rear direction of the truck 3 when it is parked at the loading stop position T in the logistics warehouse 2, and is defined as the front-rear direction X, and the up-down direction of the paper (the direction perpendicular to the front-rear direction X when viewed from the direction perpendicular to the paper) is defined as the left-right direction Y. In the front-rear direction X, the right side of the paper is defined as the front side X1, and the left side of the paper is defined as the rear side X2. The truck 3 arranged in the loading stop space 20 is parked with the loading platform 31 on the rear side X2 and the driver's seat side on the front side X1.

[0026] In the logistics warehouse 2, the front of the loading stop space 20 is the entrance 20a of the truck 3. The truck 3 is stopped at the loading stop position T of the loading stop space 20 while retreating from the entrance 20a. Each loading stop space 20A, 20B, 20C is an area in which a space for the loading stop position adjustment device 1 and a space for the passage of the unmanned loading transport device 4 are secured on both the left and right sides of one truck 3 stopped at the loading stop position T. The baggage storage space 21 is located near the rear end of the truck 3 stopped at the loading stop position T. The floor surface 20a of the loading stop space 20 is formed at a position lower than the floor surface 21a of the baggage storage space 21. In other words, it is possible to adjust the height of the loading platform 31 of the truck 3 stopped at the loading stop position T to the floor surface 21a of the baggage storage space 21.

[0027] The luggage storage space 21 has a plurality of luggage receiving sections 21A where luggage M received from a truck 3 is transported by an unmanned luggage pick-up and transport device 4 and stored in a stacked manner. The luggage M in the luggage receiving sections 21A is further loaded onto a truck 3 to be transported out by the unmanned luggage pick-up and transport device 4.

[0028] The unmanned article pick-up and transporting device 4 automatically transports the article M between the baggage storage space 21 and the loading platform 31 of the truck 3 positioned at the loading stop position T of the loading stop space 20. As described above, the unmanned article pick-up and transporting device 4 can automatically pick up and load the article M from both the left and right sides of the loading platform 31 of the truck 3. The unmanned article pick-up and transporting device 4 includes a first transporting device 4A that moves within the baggage storage space 21, and a second transporting device 4B that moves within the loading stop space 20. The article M is then handed over between the first transporting device 4A and the second transporting device 4B.

[0029] The unmanned article picking and transporting device 4 is, for example, a forklift, and is controlled to travel unmanned and to receive and load the article M. The unmanned article picking and transporting device 4 is equipped with a camera (not shown) for checking the position of the loading platform 31 of the truck 3 and the article M on the loading platform 31. The unmanned article picking and transporting device 4 is controlled to receive and load the target article M based on image information captured by the camera. In other words, in this embodiment, the truck 3 parked at the article picking stop position T is positioned at the desired position, so that the unmanned article picking and transporting device 4 is position-controlled only for the article M on the loading platform 31 of the positioned truck 3.

[0030] In this embodiment, the truck 3 has a stopping position detection unit (not shown) that detects that the truck 3 has been positioned at the loading stopping position T. This stopping position detection unit may be mounted on each unmanned goods picking and transporting device 4, or may be mounted on a centralized control unit (not shown) and transmit control information to a predetermined unmanned goods picking and transporting device 4. When the detection information is detected by the stopping position detection unit, the unmanned goods picking and transporting device 4 starts automatically removing and loading the goods M onto the loading platform 31 of the truck 3.

[0031] Next, a specific configuration of the goods pick-up stop position adjustment device 1 will be described with reference to Fig. 3 to Fig. 7. Fig. 3 is a plan view of the goods pick-up stop position adjustment device 1. Fig. 4 is a plan view of a state in which the truck 3 is positioned at the goods pick-up stop position T by the goods pick-up stop position adjustment device 1 shown in Fig. 3. Fig. 5 is a cross-sectional view taken along line II-II shown in Fig. 3, and is a cross-sectional view at the center of the goods pick-up stop position adjustment device 1 in the left-right direction.

[0032] 3 to 5, the cargo pick-up stopping position adjustment device 1 includes a rear wheel positioning unit 10 and a front wheel positioning unit 50. The cargo pick-up stopping position adjustment device 1 stops the truck 3 with its axle direction facing the front-rear direction X.

[0033] The rear wheel positioning section 10 is formed at a position lower than the floor surface of the floor structure 22 (floor surface 20a of the cargo unloading parking space 20) and guides the truck 3 in the reverse direction to position the rear wheels 32 of the truck 3 at the cargo unloading parking position T. The rear wheel positioning section 10 has a rear wheel guideway 11 formed on the floor surface 22a, guide side walls 12 provided on both the left and right sides of the rear wheel guideway 11, and a car stop wall 13 located at the rear end of the rear wheel guideway 11. The road surface center line O of the rear wheel guideway 11 coincides with the front-to-rear direction X. In addition, the rear wheel guideway 11 is inclined so as to become lower from the front to the rear.

[0034] The guide side wall 12 guides the rear wheels 32 of the truck 3 in the front-rear direction X. The guide side wall 12 has a first guide wall 121 located on the rear side and a second guide wall 122 located forward of the first guide wall 121. A width dimension D1 in the left-right direction Y of the first guide wall 121 is set to be approximately the same dimension as the distance between the outer surfaces of the left and right rear wheels 32 of the truck 3. The second guide walls 122 are provided such that the distance between the left and right second guide walls 122 gradually increases as they move forward from the first guide wall 121. The width of the second guide walls 122 is set to, for example, 150 mm on each side.

[0035] As shown in FIG. 4, the front wheel positioning unit 50 is provided on the floor structure 22, and is provided movable in the left-right direction Y to place the front wheels 33 of the truck 3 whose rear wheels 32 are positioned on the rear wheel positioning unit 10 thereon.

[0036] Fig. 6 is a plan view of the front wheel positioning unit 50 from above, with the projection of the mount omitted. Fig. 7 is a cross-sectional view taken along line III-III shown in Fig. 6. As shown in Figures 6 and 7, the front wheel positioning unit 50 is accommodated in the recess 24 of the floor structure 22 and includes a platform 51 on which the front wheels 33 of the truck 3 (see Figures 2 and 4) are placed, and an extendable cylinder 52 (movement drive device) that moves the platform 51 in the left-right direction.

[0037] The recess 24 formed in the floor structure 22 has a rectangular shape in a plan view, and is disposed on the rear side X2 of the rear wheel positioning portion 10. One of the two opposing sides of the recess 24 faces the left-right direction Y, and the other of the two opposing sides faces the front-rear direction X. A pair of guide rails 53 extending along the left-right direction Y are provided at an interval from each other on a bottom surface 24a of the recess 24.

[0038] The platform 51 has a rectangular plate shape in a plan view, and is formed in a shape smaller than the recess 24. The platform 51 is disposed at a position where the front wheels 33 (see Figs. 2 and 4) of the truck 3 parked at the cargo unloading stop position T rest on an upper surface 51c of the platform 51. A sliding wheel 54 guided by each of a pair of guide rails 53 is provided on a lower surface 51a of the platform 51. Two sliding wheels 54 are provided for each guide rail 53. The sliding wheels 54 slide on the guide rails 53, allowing the platform 51 to move in the left-right direction Y.

[0039] The upper edge of the stand 51 has a protruding portion 55 that covers the floor surface 22a around the recess 24 from above. A sliding plate 56 (sliding member) is provided between the protruding portion 55 and the floor surface 22a to reduce frictional resistance between the protruding portion 55 and the floor surface 22a.

[0040] The sliding plate 56 is fixed to the floor surface 22a, and a material with a low coefficient of friction (friction reducing material) that reduces frictional resistance between the upper surface 56a and the lower surface 55a of the overhanging portion 55 is applied or attached to the upper surface 56a. As the sliding plate 56 having this friction reducing material, for example, a plate with the upper surface 56a processed with polytetrafluoroethylene or the like can be used. In this manner, the overhanging portion 55 of the stand 51 is placed on the sliding plate 56 so that it can move.

[0041] A telescopic cylinder 52 is provided between the pair of guide rails 53, with the telescopic cylinder 52 extending in the left-right direction Y. The telescopic cylinder 52 has a main body 52a at one end fixed to the bottom surface 24a of the recess 24 of the floor structure 22, and a telescopic tip 52b at the other end fixed to the base 51. The driving method of the telescopic cylinder 52 may be electric or hydraulic.

[0042] Here, the state in which the center of the frame 51 in the left-right direction Y coincides with the road surface center line O is defined as the initial position. The telescopic cylinder 52 is installed so that it can be extended in both the left-right direction Y at the initial position of the frame 51. The adjustment range of the frame 51 in the left-right direction Y is set to ±150 mm, for example. By extending the telescopic cylinder 52, the frame 51 moves in the left-right direction Y. The front wheels 33 of the truck 3 mounted on the frame 51 can be moved in the left-right direction Y together with the frame 51 to adjust their positions in the left-right direction Y. In other words, the positions of the front wheels 33 of the truck 3 in the left-right direction Y can be adjusted to coincide with the rear wheels 32.

[0043] Next, a specific description will be given of an operational procedure for unloading and loading the cargo M onto the loading platform 31 of the truck 3 that has entered the logistics warehouse 2 in the logistics system 100 and parked at the cargo unloading stop position T. 1, 2 and 4, when the driver backs up the truck 3 from the entrance 20a of the logistics warehouse 2 and moves it toward the cargo pick-up stop position adjustment device 1 of the cargo pick-up stop space 20, the rear wheels 32 of the truck 3 are guided by the second guide wall 122 and the first guide wall 121 of the guide side wall 12 of the rear wheel positioning unit 10, in that order, and stop at the vehicle stop wall 13. This determines the position of the rear wheels 32 in the left-right direction Y and the front-rear direction X. At this time, the front wheels 33 are placed on the stands 51 of the front wheel positioning unit 50.

[0044] Here, the rear wheel guideway 11 is inclined so as to become lower toward the rear, so that the rear wheel 32 can move along the inclination toward the car stop wall 13. Also, in the rear wheel positioning section 10, the road surface width on the entrance side (front side X1) of the rear wheel guideway 11 is widened, so that the rear wheel 32 can easily enter the rear wheel guideway 11.

[0045] When the front wheels 33 are misaligned in the left-right direction Y with respect to the position of the rear wheels 32, the telescopic cylinder 52 is extended to move the platform 51 together with the front wheels 33 in either the left-right direction Y, as shown in Figs. 4 and 5. Then, the positions of the rear wheels 32 and the front wheels 33 of the truck 3 in the left-right direction Y can be aligned. This allows the truck 3 to be stopped at the loading stop position T. The amount of deviation between the front wheels 33 and the rear wheels 32 in the left-right direction Y can be detected, for example, using a sensor to control the amount of extension and contraction of the telescopic cylinder 52 (the amount of movement of the base 51).

[0046] 1 and 2, a stop position detection unit (not shown) detects that the truck 3 has been positioned at the loading stop position T. When the positioning of the truck 3 at the loading stop position T is completed, the driver of the truck 3 may transmit a completion signal.

[0047] Then, when the stopping position detection unit detects the detection information, the second conveying device 4B of the unmanned goods picking and conveying device 4 starts an operation of automatically removing the luggage M from the loading platform 31 of the truck 3 in the luggage picking stopping space 20. The second conveying device 4B temporarily stores the removed luggage M in the temporary storage area 21b on the floor surface 21a of the luggage storage space 21. After that, the first conveying device 4A of the unmanned goods picking and conveying device 4 automatically holds the luggage M in the temporary storage area 21b in the luggage storage space 21. The first conveying device 4A stores the held luggage M in a stacked manner in the luggage receiving section 21A of the luggage storage space 21.

[0048] Next, when the truck 3 for unloading luggage stops at the luggage pick-up stop position T and the stop position detection unit detects the detection information, the operation of loading luggage M onto the loading platform 31 of the truck 3 is started. In the luggage receiving unit 21A of the luggage storage space 21, the first transport device 4A of the unmanned luggage pick-up transport device 4 automatically holds the desired luggage M and temporarily stores it in the temporary storage area 21b. After that, in the luggage pick-up stop space 20, the second transport device 4B automatically holds the luggage M in the temporary storage area 21b and transports it toward the loading platform 31 of the truck 3, and the luggage M is automatically loaded into a predetermined position on the loading platform 31 of the truck 3.

[0049] Next, the operation of the above-mentioned logistics system 100 will be described in detail with reference to the drawings. In the logistics system 100 according to this embodiment, a luggage storage facility is provided with a luggage pick-up stop position adjustment device 1 for a truck 3 for positioning the truck 3 at a luggage pick-up stop position T where luggage M can be automatically removed and loaded by an unmanned luggage pick-up transport device 4 with respect to the loading platform 31 of the truck 3. The logistics warehouse 2 is provided with a luggage storage space 21 for storing luggage M, and a luggage pick-up stop space 20 having a luggage pick-up stop position T. The luggage pick-up stop position adjustment device 1 is provided with a rear wheel positioning unit 10 formed at a position lower than the floor surface 22a of the floor structure 22 of the luggage pick-up stop space 20 and for guiding the truck 3 in the backward direction to position the rear wheels 32 of the truck 3 at the luggage pick-up stop position T, and a front wheel positioning unit 50 provided on the floor structure 22, on which the front wheels 33 of the truck 3 whose rear wheels 32 are positioned in the rear wheel positioning unit 10 are placed, and which is movable in the left-right direction Y perpendicular to the traveling direction of the truck 3. The unmanned load-handling transport device 1 automatically transports loads M between a load storage space 21 and a loading platform 31 of a truck 3 positioned at a load-handling stop position T in a load-handling stop space 20.

[0050] In this manner, in this embodiment, when unloading and loading onto the bed 31 of the truck 3, the truck 3 is moved backward to guide the rear wheels 32 into the rear wheel positioning portion 10 formed at a position lower than the floor surface 22a of the floor structure 22, thereby positioning the rear wheels 32 in the front-rear direction X and the left-right direction Y. In the rear wheel positioning portion 10, the portion on which the front wheels 33 are placed can be moved in the left-right direction Y, so that the position of the front wheels 33 in the left-right direction Y can be adjusted. As a result, the cargo unloading stop position adjustment device 1 having a simple configuration can easily and quickly position the truck 3 at the cargo unloading stop position T with the positions of the rear wheels 32 and the front wheels 33 of the truck 3 aligned in the left-right direction Y.

[0051] In this manner, in this embodiment, the truck 3 can be accurately positioned at the loading stop position T, so that the unmanned loading and transporting device 4 can efficiently transport the luggage M between the luggage storage space 21 and the loading platform of the truck 3 positioned at the loading stop position T in the loading stop space 20 in an unmanned manner. This reduces the burden of manual loading work, and enables loading work to be performed at a luggage storage facility such as the logistics warehouse 2 regardless of the time of day, such as at night.

[0052] Furthermore, in this embodiment, the cargo unloading stop position adjustment device 1 can be installed in advance on the building structure, eliminating the need to install expensive sensors or cameras, and also eliminating the need for maintenance of these and positioning control, thereby enabling a reduction in equipment costs for adjusting the stop position of the truck 3.

[0053] In this embodiment, the unmanned article pick-up and transport device 4 can automatically pick up and load articles from both the left and right sides of the bed of the truck 3. With this configuration, the unmanned cargo pick-up and transport device 4 can be placed close to both the left and right sides of the loading platform 31 of the truck 3, and cargo M can be unloaded and loaded from both sides of the truck 3, thereby improving work efficiency.

[0054] In addition, in this embodiment, the unmanned luggage pick-up and transport device 4 is equipped with a first transport device 4A that moves within the luggage storage space 21 and a second transport device 4B that moves within the luggage pick-up stop space 20, and luggage M is handed over between the first transport device 4A and the second transport device 4B. With this configuration, even if there is a step in the floor between the luggage storage space 21 and the luggage unloading stop space 20, a first conveying device 4A and a second conveying device 4b dedicated to each space 20, 21 are provided, and the transfer of luggage M between the first conveying device 4A and the second conveying device 4B can be carried out efficiently in an unmanned manner.

[0055] In addition, in this embodiment, the truck 3 has a stopping position detection unit that detects when it is positioned at the cargo pick-up stopping position T, and when the detection information is detected by the stopping position detection unit, the unmanned cargo pick-up and transport device 4 automatically starts the operation of removing and loading the cargo M onto the bed of the truck 3. In this embodiment, when the stopping position detection unit detects detection information when unloading luggage from the bed of the truck 3, control can be performed to start the operation of automatically unloading luggage M from the bed 31 of the truck 3 by the unmanned luggage unloading and transporting device 4 in the luggage unloading stop space 20. On the other hand, when the stopping position detection unit detects detection information when loading luggage M from the luggage storage space 21 onto the bed of the truck 3, control can be performed to start the operation of loading luggage M onto the bed 31 of the truck 3.

[0056] As described above, in the logistics system 100 according to this embodiment, the truck 3 can be positioned at the cargo unloading stop position easily and in a short time, and the efficiency of the entire system can be improved, including automatic unloading and loading of cargo onto the truck 3.

[0057] Although an embodiment of the logistics system according to the present invention has been described above, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the present invention.

[0058] For example, the configurations of the rear wheel guideway 11, the guide side wall 12, and the wheel stop wall 13 in the rear wheel positioning portion 10 of this embodiment, or the configuration of the front wheel positioning portion 50 are not limited to this embodiment and can be changed as appropriate.

[0059] In addition, in this embodiment, the unmanned cargo pick-up and transport device 4 is configured to automatically remove and load cargo M from both the left and right sides of the cargo bed 31 of the truck 3, but the method is not limited to access from both the left and right sides of the cargo bed 31, and access from only one side is also possible.

[0060] Furthermore, in this embodiment, the unmanned cargo pick-up and transport device 4 is configured to include a first transport device 4A that moves within the baggage storage space 21, and a second transport device 4B that moves within the baggage pick-up stop space 20. However, for example, in the case of a floor structure 22 in which the baggage storage space 21 and the baggage pick-up stop space 20 are connected by a flat floor surface with no steps between them as in this embodiment, it is not necessary to have dedicated transport devices 4A, 4B for the baggage storage space 21 and the baggage pick-up stop space 20, respectively, and an unmanned cargo pick-up and transport device 4 may be used that can be shared by each space 20, 21.

[0061] In addition, in this embodiment, the configuration is such that a stop position detection unit is provided that detects that the truck 3 has been positioned at the loading stop position T, but the stop position detection unit may be omitted. For example, as described above, after the positioning of the truck 3 at the loading stop position T is completed, the driver of the truck 3 may transmit a completion signal.

[0062] In the above embodiment, the truck 3 is used as the vehicle of the cargo unloading stop position adjustment device 1, but the shape and size of the vehicle are not particularly limited and may be any shape and size.

[0063] In addition, the components in the above-described embodiments can be replaced with well-known components as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
