[0010] The present invention will be described below based on preferred embodiments with reference to the drawings. In the embodiments, comparative examples, and modified examples, the same or equivalent components and members are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. Some of the members that are not important for explaining the embodiments are omitted in each drawing.

[0011] In addition, terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another component, and the components are not limited by these terms.

[0012] [First embodiment] The configuration of an automated warehouse system according to an embodiment will be described with reference to the drawings. FIG. 1 is a plan view that shows an example of an automated warehouse system according to an embodiment. FIG. 2 is a plan view that shows the arrangement of storage shelves in the automated warehouse system. FIG. 3 is a front view that shows an example of the automated warehouse system. FIG. 4 is a front view that shows the arrangement of storage shelves in the automated warehouse system. In these figures, the illustration of pillars, beams, and the like that are not important for the explanation are omitted, and the same applies to the following figures.

[0013] For convenience of explanation, as shown in the figure, an XYZ orthogonal coordinate system is defined in which a certain horizontal direction is the X direction, a horizontal direction perpendicular to the X direction is the Y direction, and a direction perpendicular to both, i.e., a vertical direction, is the Z direction. Note that, in the following explanation, the XYZ orthogonal coordinate system is used for explanation, but the X direction, Y direction, and Z direction do not necessarily have to be perpendicular to each other, as long as they intersect at approximately 90 degrees. The positive directions of the X axis, Y axis, and Z axis are defined as the directions of the arrows in each figure, and the negative directions are defined as the directions opposite to the arrows. In addition, the positive direction side of the X axis is sometimes called the "right side", and the negative direction side of the X axis is sometimes called the "left side". In addition, the positive direction side of the Y axis is sometimes called the "front side", the negative direction side of the Y axis is sometimes called the "rear side", the positive direction side of the Z axis is sometimes called the "upper side", and the negative direction side of the Z axis is sometimes called the "lower side". Such directional notations do not limit the configuration of the automated warehouse system, and the automated warehouse system can be used in any configuration depending on the application.

[0014] First, the overall configuration of the automated warehouse system 1 will be described. The automated warehouse system 1 is a system including a storage shelf 4 capable of storing a large number of items 2. The automated warehouse system 1 includes the storage shelf 4, a first cart 6, a second cart 8, a first rail 10, a second rail 12, a power supply unit (not shown), and a control unit 14. The storage shelf 4 stores the items 2. In this embodiment, the X-axis direction is exemplified as the first direction. The first rail 10 and the second rail form a passage for transporting the items 2. The first rail 10 extends in the X-axis direction, and the second rail 12 extends in the Y-axis direction.

[0015] The first carriage 6 runs in the X-axis direction on the first rail 10. The second carriage 8 runs in the Y-axis direction on the second rail 12. The first carriage 6 and the second carriage 8 are sometimes collectively referred to simply as carriages. Also, the first carriage 6, the second carriage 8, the first rail 10, and the second rail 12 are sometimes collectively referred to simply as the "internal transport mechanism." The control unit 14 controls the operation of the first carriage 6 and the second carriage 8.

[0016] In the first embodiment, the load 2 is handled while placed on the pallet 16, but this is not limited thereto, and the load 2 may be handled independently without using the pallet 16. Transporting the load 2 while placed on the pallet 16 is simply referred to as transporting the load 2.

[0017] The loading and unloading operations of the automated warehouse system 1 will be described. The automated warehouse system 1 loads the goods 2 from outside the warehouse into the receiving section 18, for example, by a forklift (not shown). The automated warehouse system 1 transports the goods 2 loaded into the receiving section 18 to a specified storage section 20 by an internal transport mechanism including a first cart 6 and a second cart 8, and stores the goods. The automated warehouse system 1 also transports the goods 2 stored in the specified storage section 20 to an unloading section 22 by the internal transport mechanism. The automated warehouse system 1 unloads the goods 2 transported to the unloading section 22 outside the warehouse, for example, by a forklift.

[0018] (Storage shelf) The storage shelf 4 is a so-called high-density storage type storage space capable of storing a large number of goods 2. The configuration of the storage shelf 4 is not particularly limited as long as it is capable of accommodating and storing a plurality of goods 2. In this example, the storage shelf 4 includes a plurality of storage stages 24 (e.g., four stages) stacked in layers in the vertical direction. Each storage stage 24 includes a plurality of storage rows 26 (e.g., six) arranged in the Y-axis direction. Each of the six storage rows 26 includes a plurality of storage sections 20 (e.g., twelve) arranged in the X-axis direction. The number of storage rows 26, the number of storage sections 20 in each storage row 26, and the position of the second rail 12 can be appropriately changed according to the shape of the warehouse. The storage section 20 is a unit for storing goods 2.

[0019] Here, each of the multiple storage stages 24 is provided with an entrance section 18 and an exit section 22, and the goods 2 may be carried in and out of each storage stage 24 by a forklift. Alternatively, a lifting mechanism (not shown) for raising and lowering the goods 2 may be provided separately for each storage stage 24, and the entrance section 18 and the exit section 22 may be provided only for the lowest storage stage 24. In this case, the goods 2 received from the entrance section 18 are raised by the lifting mechanism and moved to each storage stage 24, and the goods 2 exited from each storage stage 24 are lowered by the lifting mechanism and exited to the exit section 22.

[0020] (rail) The first rail 10 extends in the X-axis direction in the storage row 26. The second rail 12 extends in the Y-axis direction near the end of the storage row 26. The first rail 10 and the second rail 12 are sometimes collectively referred to simply as rails. In this specification, a rail is a member or part having a rolling surface of a wheel configured to run a cart in its extension direction. Therefore, the rail may be a rail having a rolling surface formed on a rod-shaped or band-shaped member, or a rail having a rolling surface formed on a plane.

[0021] (First cart) Next, the first carriage 6 will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a plan view that shows a schematic diagram of an example of the first carriage. Fig. 6 is a side view of the first carriage. The first carriage 6 travels on the first rail 10 in the X-axis direction in the storage row 26 in order to transport the goods 2. The first carriage 6 takes the goods 2 in and out of the storage section 20. The first carriage 6 travels on the second carriage 8 in the X-axis direction in order to get on and off the second carriage 8.

[0022] The first cart 6 mainly includes a car body 28, a platform 30, a lift mechanism 32, a plurality of (for example, four) wheels 34, and a battery 36. The car body 28 has a contour of a substantially rectangular parallelepiped shape that is flat in the vertical direction. Inside the car body 28, a motor (not shown) that drives the plurality of wheels 34, a control circuit (not shown) that controls the motor, and a battery 36 are mounted. The first cart 6 is configured to drive the motor using power from the battery 36. The battery 36 may be a secondary battery such as a repeatedly rechargeable lithium ion battery.

[0023] The placement section 30 is a section that lifts and holds the load 2. The lift mechanism 32 is a mechanism that raises and lowers the placement section 30. In FIG. 6, the placement section 30 shown by the dashed line is in a raised state, and the placement section 30 shown by the solid line is in a lowered state. The lift mechanism 32 can raise the placement section 30 to lift the load 2 from the storage section 20. The lift mechanism 32 can lower the placement section 30 to unload the load 2 into the storage section 20. The multiple wheels 34 run on the first rail 10 and the second cart 8.

[0024] (Second bogie) Next, the second carriage 8 will be described with reference to Fig. 7 and Fig. 8. Fig. 7 is a plan view that shows a schematic diagram of an example of the second carriage. Fig. 8 is a side view of the second carriage. The second carriage 8 travels on the second rail 12 in the Y-axis direction. The second carriage 8 transports the first carriage 6 in an empty state or in a state in which the load 2 is loaded.

[0025] The second bogie 8 mainly includes a car body 38, a recess 40, a plurality of wheels 42, and a current collecting unit 44. The car body 38 has a contour of a substantially rectangular parallelepiped shape that is flat in the vertical direction. Inside the car body 38, a motor (not shown) that drives each wheel 42 and a control circuit (not shown) that controls the motor are mounted. The wheels 42 run on the second rail 12. The current collecting unit 44 is in contact with a power supply line 46 described later and receives a supply of power. The second bogie 8 receives power from the power supply line via the current collecting unit 44. The second bogie 8 is configured to drive the motor with the received power and to supply power to the first bogie 6.

[0026] The second bogie 8 has a concave recess 40 for mounting the first bogie 6. The recess 40 is formed by being recessed downward from the upper surface of the car body 38 in order to mount the first bogie 6. The size of the recess 40 is determined by adding a sufficient margin to the size of the first bogie 6 so that the first bogie 6 can run in the X-axis direction without interfering with the periphery of the recess 40. The first bogie 6 runs on the recess 40.

[0027] (Maintenance area) Each storage stage 24 is provided with a maintenance area 48 into which at least the second cart 8 can enter. The maintenance area 48 is disposed at the end of the second rail 12. The maintenance area 48 is provided with a door 50 so that the inside of the maintenance area 48 can be accessed from the outside. The maintenance area 48 has a worker protection structure that can ensure the safety of workers even if a load collapse occurs in the upper storage stage 24. The worker protection structure is a structure having a solid floor and ceiling with no gaps, and is a structure that protects workers from objects falling from above and prevents objects from falling downward. By moving the second cart 8 to the maintenance area 48, the worker can perform maintenance on the second cart 8. In addition, by moving the second cart 8 to the maintenance area 48 with the first cart 6 loaded thereon, maintenance on the first cart 6 can also be performed.

[0028] A control panel 52 is provided near a door 50 for accessing the maintenance area 48. The control panel 52 is provided with a switching means such as a key switch 54 for switching the operation mode of the automated warehouse system 1. By operating the key switch 54, the operation of the internal transport mechanism, which is in fully automatic operation, can be switched on / off. The key switch 54 is linked to the lock of the door 50, and the door 50 cannot be opened unless the transport mechanism is stopped by the key switch. Therefore, an operator can enter the maintenance area 48 only when the internal transport mechanism is stopped by operating the key switch and the safety of the storage stage 24 is ensured.

[0029] The maintenance area 48 is located on an extension of the frontmost storage row 26 along the Y axis when the storage stage 24 is viewed in plan, and the second rail 12 extends to a position close to the maintenance area 48. Within the maintenance area 48, a walking assistance cart is arranged as a moving body.

[0030] (Walking assistance trolley) Fig. 9 is a perspective view of the walking aid cart, and Fig. 10 is a front view of the walking aid cart. The XYZ Cartesian coordinates shown in Figs. 9 and 10 indicate the directions when the walking aid cart 60 is placed on the second rail 12 so that the front of the walking aid cart 60 faces the -Y direction shown in Fig. 1 and the like. As shown in Figs. 9 and 10, the walking aid cart 60 mainly includes a frame portion 62 that forms a working space for an operator, and a cart portion 64 that supports the frame portion 62 movably on the rail. The walking aid cart 60 has a size and shape that cannot pass through gaps in the floor of the storage stage 24.

[0031] The frame portion 62 of the walking aid cart 60 has a frame structure, for example, by combining a plurality of aluminum beams and columns, and an internal work space 66 for work is surrounded by the frame structure. By making the walking aid cart 60 a frame structure, the walking aid cart 60 can be made lighter, and the walking aid cart 60 can be easily carried by a worker. The height H of the frame portion 62 can be appropriately set between about 1 m and 1.5 m. More specifically, the height H of the frame portion 62 is set to the height of the worker's waist or to a certain degree higher. By setting the height H of the frame portion 62 in such a range, the worker will not fall even if he leans on the frame portion 62 during work, and the worker can work by leaning his upper body from above the frame portion 62 to the outside of the work space 66. The width W of the frame portion 62 can be set appropriately to match the width of the rail to be installed, but it is preferable to set it to approximately 0.8 m so that a single worker can grasp both ends of the frame portion 62 with his or her arms outstretched and lift the walking aid cart 60.

[0032] It is preferable that the frame portion 62 has multiple beams 68 on the front side of the walking aid cart 60 and one beam 70 on the rear side. By arranging multiple beams 68 on the front side, it is possible to prevent the worker from erroneously going out to the front side. On the other hand, by providing beams 70 only at the top of the walking aid cart in the height direction on the rear side, it becomes easier for the worker to enter the working space 66. In the illustrated example, the number of beams 70 on the rear side is reduced to improve access to the working space 66, but an openable door may be provided on the rear side. In this case, it is also preferable that the door has a frame structure.

[0033] The frame portion 62 also functions as a safety belt attachment portion. The frame portion as a safety belt attachment portion is formed so that the hook of the lanyard of the safety belt can be engaged. For example, when the beam 70 on the rear side of the walking assistance cart 60 is used as the safety belt attachment portion, only this beam 70 may be formed of steel or the like having high bending rigidity, or a reinforcing structure for increasing the bending rigidity of the beam may be provided. In the illustrated example, the safety belt attachment portion is the frame portion 62, but an engagement portion capable of engaging with a hook may be provided in the working space 66 or at a position higher than the working space, separate from the frame portion 62, and this engagement portion may be used as the safety belt attachment portion.

[0034] The cart portion 64 includes a plurality of wheels 72 that roll on the rails, a stopper 74 for fixing the walking aid cart 60 in a fixed position, and a guide roller 76 that contacts the side of the rail. It is preferable that the plurality of wheels 72 are provided in a total of four, one each in the front, rear, left and right directions of the walking aid cart 60.

[0035] The cart portion 64 is formed to be wider than the frame portion as a whole. Therefore, when the walking aid cart 60 is viewed from the front, the walking aid cart 60 has a shape in which the lower side is wider as a whole. This makes it difficult for the walking aid cart 60 to tip over in the width direction.

[0036] Fig. 11 is an enlarged perspective view of the walking aid cart, and in particular an enlarged perspective view showing the stopper 74. As shown in Fig. 11, the stopper 74 fixes the position of the walking aid cart 60 so that the walking aid cart 60 does not move in the extension direction of the rail when the walking aid cart 60 is stopped at a predetermined position. The stopper 74 is formed by, for example, a drop hinge provided at the lower part of the cart portion 64. The stopper 74 is housed so as not to protrude from below the cart portion 64 when released, and protrudes from below the cart portion 64 when activated and engages with an engagement hole provided in the floor surface.

[0037] FIG. 12 is an enlarged front view of the walking aid cart, and in particular, an enlarged front view showing the guide roller. As shown in FIG. 12, the guide roller 76 is provided with a pair of rollers 78 that rotate around the Z axis. The pair of rollers 78 are arranged with a small gap in the width direction. When the walking aid cart 60 is arranged on the rail, the pair of rollers 78 sandwich a guide rail 80 (shown by a broken line in FIG. 12) that extends together with the rail and has a substantially L-shaped cross section. In the illustrated example, the walking aid cart 60 is provided with two guide rollers 76 on one side in the width direction of the walking aid cart 60. The two guide rollers 76 are arranged separately in the front-rear direction, which makes it possible to prevent the wheels 72 from coming off. In addition, by providing the guide rollers 76, the moving direction of the walking aid cart 60 can be limited to the extension direction of the rail.

[0038] 9 and 10 again, the walking aid cart 60 is provided with four tip-prevention arms 82 extending in the front-rear direction. The tip-prevention arms 82 have a rod-like shape extending along the Y-axis from the lower part of the walking aid cart. Providing the tip-prevention arms 82 makes it difficult for the walking aid cart 60 to tip in the front-rear direction. The tip-prevention arms 82 are formed so as to be pivotable about the X-axis by means of lockable hinges 84, and can be folded so as to extend along the Z-axis when the walking aid cart 60 is not in use.

[0039] The walking aid cart 60 may also have an additional friction stopper 86. The friction stopper 86 is provided, for example, adjacent to the wheel 72, and moves so as to contact or move away from the upper surface of the rail by operating in the vertical direction. The friction stopper 86 is formed of a material with high friction force, such as rubber, and is screw-engaged to the bottom of the walking aid cart 60. When the walking aid cart 60 is stopped at a desired position and the friction stopper 86 is rotated, the friction stopper 86 moves downward and contacts the upper surface of the rail. Such a friction stopper 86 allows the walking aid cart 60 to be stopped more reliably at a desired position.

[0040] Next, the operation of the walking aid cart 60 will be described. When the walking aid cart 60 is not in use, the walking aid cart 60 is placed, for example, in the maintenance area 48 with the tip-over prevention arm 82 folded. When the walking aid cart 60 is to be used, the worker turns off the key switch 54, unlocks the door 50, and then enters the maintenance area 48. The worker lifts the walking aid cart 60, places the walking aid cart 60 on the second rail 12, and unfolds the tip-over prevention arm 82 in front and behind. At this time, the wheels 72 of the walking aid cart 60 are placed on the upper surface of the second rail, and the guide rail 80 is placed between the pair of rollers 78.

[0041] When the worker moves along the second rail 12, the worker passes through the beam 70 from the rear side of the walking aid cart 60 and enters the working space 66. Next, the worker attaches the hook of the lanyard to the safety belt attachment part of the frame structure (the beam 70 in this example). Next, when the worker pushes the walking aid cart 60, the wheels 72 roll on the second rail 12 and the walking aid cart 60 moves. At this time, the worker walks on the floor of the storage stage 24 within the working space 66 of the walking aid cart 60 and moves. When the walking aid cart 60 and the worker reach the desired position, the worker stops the movement of the walking aid cart 60 and activates the stopper 74 and, if provided, the friction stopper 86 to fix the walking aid cart 60 in a fixed position. The worker performs the desired work within the working space 66 of the fixed walking aid cart 60. When the work is completed, the worker releases the stopper 74 and the friction stopper 86, and returns to the maintenance area 48 while pushing the walking assistance cart 60.

[0042] Such a walking aid cart 60 is used when a worker enters the inside of the storage shelf 4 for maintenance or the like. When a lifeline for attaching a hook of a lanyard of a safety belt worn by a worker is to be permanently installed on the storage stage 24 in the storage shelf 4, the lifeline needs to be installed at a position higher than the space through which the load 2 passes in order to avoid interference between the lifeline and the load 2. However, when the lifeline is to be installed at a position higher than the space through which the load 2 passes, the height of each storage stage 24 needs to be increased. Therefore, when a lifeline for attaching a lanyard is permanently installed, the height of each storage stage 24 needs to be increased, which results in a decrease in the storage efficiency of the entire warehouse. In contrast, when a worker uses the walking aid cart 60 when entering the storage shelf 4 and attaches a lanyard to the walking aid cart 60, there is no need to permanently install the lifeline.

[0043] The walking aid cart 60 may also be used when performing work to temporarily install or retrieve the lifeline in the storage shelf 4. In this case, a plurality of lifeline posts are arranged at predetermined intervals along the second rail 12 of the storage shelf 4 in advance. The lifeline posts are installed in positions that do not interfere with the load 2 when the cart transports the load. The worker attaches the lifeline to the lifeline posts one by one while moving with the walking aid cart 60. After that, the worker returns the walking aid cart 60 to the maintenance area 48, replaces the lanyard with the lifeline, and performs work in the storage shelf 4. After completing the work, the worker uses the walking aid cart 60 again to remove and retrieve the lifeline. By being able to temporarily install the lifeline in this way, it is possible to prevent interference between the lifeline and the load. In particular, by being able to temporarily install the lifeline, it is possible to place the lifeline at a high position in the storage stage 24 without increasing the height of the storage stage 24, thereby further improving the safety of the worker. In particular, the height of the topmost storage stage 24 may be limited by the roof of the warehouse, but by making it possible to temporarily install the lifeline only during work and at a higher position where greater safety can be ensured, the safety of workers can be ensured regardless of the height of the warehouse roof.

[0044] The present invention has been described above based on the embodiments. These embodiments are merely examples, and it is understood by those skilled in the art that various modifications and changes are possible within the scope of the claims of the present invention, and that such modifications and changes are also within the scope of the claims of the present invention. Therefore, the descriptions and drawings in this specification should be treated as illustrative rather than restrictive.

[0045] (Modification) The following describes a modified example. It is not essential to provide the walking assistance cart 60 at each storage stage 24. The walking assistance cart 60 may be provided at only some of the storage stages 24, and the walking assistance cart 60 may be transported using an elevator as necessary.

[0046] The storage stage 24 may consist of one column of storage rows 26 .

[0047] It is not essential that the number of storage sections 20 in the storage row 26 is uniform. Depending on the irregularities of the walls of the building that houses the storage shelves 4, some storage rows 26 may have a larger number of storage sections 20 than others.

[0048] It is not essential that the number of stages of the vertically stacked storage rows 26 be uniform. The number of stages of the storage stage 24 may be such that some areas have more stages than others, depending on the ceiling height of the building that houses the storage shelves 4.

[0049] It is not essential that the load 2 includes a pallet 16. The present automated warehouse system may be adapted to handle loads 2 that do not include a pallet.

[0050] Instead of a forklift, the load 2 may be carried in and out by another type of transfer device, such as a transfer device equipped with a crane.

[0051] Each of these modified examples provides the same effects as the embodiment.

[0052] Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. A new embodiment resulting from the combination has the combined effects of the respective embodiments and modifications. [Explanation of symbols]
