Description

[Technical field]

[0001] The present invention relates to a transport device and a method for connecting a transport device. [Background technology]

[0002] 2. Description of the Related Art A transport device for transporting materials and equipment at a construction site or the like is known.

[0003] For example, a method of transporting materials and equipment using so-called containers is known. Specifically, first, the containers are stored in a folded state. Then, when the materials and equipment are to be transported, the containers are assembled. Once the containers are assembled in this way, the materials and equipment can be stored in the containers. Therefore, a method of transporting materials and equipment is known in which the containers are assembled, the materials and equipment are stored in the containers, and then the containers storing the materials and equipment are moved to transport the materials and equipment (for example, Non-Patent Document 1, etc.).

[0004] Also, a method of transporting materials and equipment by using an AGV (Automated Guided Vehicle) is known. Specifically, a method of improving labor productivity by automatically transporting materials and equipment in a horizontal direction by an AGV having a horizontal transport means for loading and unloading materials and equipment is known (for example, Patent Document 1, etc.).

[0005] In addition, a forklift or a lifting lift may be used to transport materials and equipment to a work area or a stockyard at a construction site. By using a forklift or a lifting lift, materials and equipment can be transported to multiple floors. Therefore, a method is known in which materials and equipment are automatically transported to a position where a predetermined task is to be performed using a forklift or a lifting lift (for example, Patent Document 2, etc.).

[0007] [Non-Patent Document 1] Asahi Kizai Co., Ltd., "E-Container", [online], September 2011, [Retrieved November 19, 2019], Internet <URL: http: / / www.asahikizai.com / wp-content / uploads / 2018 / 10 / e_container_okyaku.pdf> Summary of the Invention [Problem to be solved by the invention]

[0008] However, in many cases, conventional conveying devices cannot be used as a so-called scaffold, i.e., workers cannot stand on the conveying device to perform work on high places such as ceilings.

[0009] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a transport device on which a worker can ride. [Means for solving the problem]

[0010] The transport device and the transport device connecting method according to each embodiment of the present invention have, for example, the following configuration.

[0011] A transport device for transporting materials and equipment (for example, the transport device 100 shown in FIG. 1) A side portion (e.g., a side plate PT shown in FIG. 18) that forms a space (e.g., a space SP shown in FIG. 1) for storing the materials and equipment; A ceiling portion (e.g., a ceiling CE shown in FIG. 18 ) that is perpendicular to the side portion and forms a ceiling of the space, The side surface portion is movable in a height direction, When the side portion moves upward in the height direction, it becomes a handrail (for example, the handrail HR shown in FIG. 21) when a worker climbs onto the ceiling and works thereon. Or, When the side portion moves upward in the height direction, rotates, and connects to another transport device, it becomes a scaffold (for example, the side panel PT shown in Figure 20) for the worker to board and work on.

[0012] With such a configuration, for example, a transport device on which a worker can ride can be made as shown in FIG.

[0013] In addition, the side surface portion is The portion in contact with another transport device has a shape that is partly or entirely thin (such as the connecting portion CN shown in FIG. 22 or a connecting portion using the tip portion shaped as shown in FIG. 29).

[0014] In particular, the side portion is It has an L-shape that is partly or entirely tapered toward the other transport device (such as the tip portion PTL shown in FIG. 22).

[0015] In addition, the tip of the side surface portion and the ceiling portion of the other conveying device are connected to each other at a contact point, The tip portion has a shape in which a part or the whole of the tip portion is thinned (for example, a tip portion having a shape as shown in FIG. 29 is used and connected as shown in FIG. 30, etc.).

[0016] In this way, if the thickness is reduced, the step can be reduced.

[0017] In addition, a conveying device for conveying materials and equipment (for example, the conveying device 100 shown in FIG. 1) A side portion (e.g., a side plate PT shown in FIG. 23) that forms a space (e.g., a space SP shown in FIG. 1) for storing the materials and equipment; A ceiling portion (e.g., a ceiling CE shown in FIG. 18 ) that is perpendicular to the side portion and forms a ceiling of the space, The side surface portion is It is connected to other conveying devices at either a first height (for example, the first height H1 shown in FIG. 23) or a second height lower than the first height (for example, the second height H2 shown in FIG. 23), and serves as a scaffold for workers to board and work on (for example, either FIG. 21 or FIG. 25).

[0018] With such a configuration, for example, a transport device on which a worker can ride can be made as shown in FIG. 21 or FIG.

[0019] Moreover, the side portion is slid to switch between the first height and the second height (for example, from the first height H1 to the second height H2 shown in FIG. 23).

[0020] With such a configuration, for example, a transport device on which a worker can ride can be made as shown in FIG. 21 or FIG.

[0021] In addition, at least one side in the horizontal direction or the depth direction (for example, the side in the X-axis direction or the Y-axis direction shown in FIG. 28) has a dimension of 1060 mm or less. In this way, if the conveying device 100 is small, multiple conveying devices 100 can be mounted on a truck or the like.

[0022] In addition, the side surface portion is The side portion is movable in the height direction, and when the side portion moves upward in the height direction, it becomes a handrail when a worker boards the ceiling portion to work (for example, the handrail HR shown in Figure 2 (A)).

[0023] With the above configuration, the transport device 100 has a ceiling portion so that workers can ride on it. In this way, the transport device 100 is configured to transport materials and equipment to a work site and to be used as a scaffold at the work site.

[0024] Also, it is desirable to have a configuration in which, when the side surface portion moves upward in the height direction, an opening portion (such as an opening portion OP shown in FIG. 2(A)) is formed in the space.

[0025] With the above-mentioned configuration, it is possible to remove materials and equipment that have been installed in advance from the opening OP, or to store materials and equipment in the space SP.

[0026] In addition, when the side surface portion moves upward in the height direction, A configuration in which the handrail is at a height of 900 mm or more from the ceiling (for example, as shown in FIG. 2(A)) is desirable.

[0027] With the above-mentioned configuration, the conveying device 100 satisfies the requirements stipulated in the Industrial Safety and Health Regulations and can prevent the worker MN or the like from falling.

[0028] In addition, the ceiling portion is A configuration in which the height from the floor surface is less than 2000 mm and is equal to or greater than 1500 mm (for example, the height of the conveying device 100 in the Z-axis direction shown in FIG. 1(A)) is desirable.

[0029] With the above-mentioned configuration, the transport device 100 can be used as a foothold for work at height, and can be easily installed.

[0030] Moreover, it is preferable that the transport device 100 further includes an auxiliary plate for closing a gap occurring at the boundary between the side surface portion and another side surface portion.

[0031] With the above-mentioned configuration, the conveying device 100 can prevent accidents such as tripping.

[0032] The method of connecting the transport device is as follows: A side portion that forms a space for storing materials and equipment; a ceiling portion that is perpendicular to the side portion and forms a ceiling of the space, A procedure for installing a handrail when a worker works on the ceiling by moving the side portion upward in a height direction. Or, The side surface portion is This includes any of the procedures of connecting the device to another transport device and forming a scaffold when the worker boards the device to work (for example, a connecting method as shown in FIG. 17).

[0033] By using the above-mentioned connection method, the transport device can be turned into a scaffold on which workers can stand.

[0034] The method of connecting the transport device is as follows: A side portion that forms a space for storing materials and equipment; a ceiling portion that is perpendicular to the side portion and forms a ceiling of the space, a determination step of determining a height at which the conveying device is connected to another conveying device, either a first height or a second height lower than the first height; a step of connecting the side portion of the scaffolding to another transport device at either the first height or the second height selected in the determination step, and forming a scaffolding for a worker to board and work on the scaffolding; (For example, the connection method shown in FIG. 27).

[0035] By using the above-mentioned connection method, the transport device can be turned into a scaffold on which workers can stand. Effect of the Invention

[0036] According to each embodiment of the present invention, a transport device on which a worker can ride can be provided. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] The following description will be given with reference to the drawings, focusing on the optimal and minimum mode for carrying out the invention. Note that in the drawings, when the same reference numerals are used, it indicates that the configuration is the same, and duplicated explanations will be omitted. Also, the specific examples shown in the drawings are merely examples, and the configuration may further include configurations other than those shown in the drawings.

[0039] First Embodiment <Example of transport device configuration> FIG. 1 is a diagram showing an example of a conveying device. Hereinafter, the conveying direction in which materials and equipment are conveyed by the conveying device 100 is referred to as the "Y-axis direction." The direction perpendicular to the Y-axis is referred to as the "X-axis direction." Therefore, the XY plane is a plane parallel to the floor surface GD. Furthermore, the height direction is referred to as the "Z-axis direction."

[0040] Fig. 1(A) is a side view, Fig. 1(B) is a front view, and Fig. 1(C) is a plan view.

[0041] As shown in the figure, the conveying device 100 has a length of 4200 millimeters in the Y-axis direction. The conveying device 100 has a height of 1950 millimeters in the Z-axis direction. The conveying device 100 has a width of 900 millimeters in the X-axis direction.

[0042] The materials and equipment are tools used in work at a construction site, components and materials installed in a building, or accessories associated with these, etc. For example, components installed in a building are pipes, ducts, air conditioners, fans, or hanging jigs for installing these on the ceiling of the building.

[0043] As shown in FIG. 1(A), the conveying device 100 is configured to include a mesh ME, which is an example of a side portion. Specifically, the mesh ME is a plate material or the like installed in the Y-axis direction. The illustrated example is an example in which four mesh MEs are installed in the Y-axis direction. Furthermore, the illustrated example is an example in which a mesh ME is also installed in the X-axis direction, i.e., at a position that is the front side. In this manner, multiple mesh MEs are installed on the side surfaces.

[0044] 1C, the transport device 100 includes a ceiling plate PL, which is an example of a ceiling portion, in a direction perpendicular to the side surface (on the XY plane in the figure). That is, the ceiling plate PL is a plate that forms the ceiling of the transport device 100.

[0045] As shown in the figure, materials and equipment are stored in an inner space SP surrounded by a ceiling board PL and a mesh ME. Therefore, after the materials and equipment are stored in the space SP, the materials and equipment can be transported by moving the transport device 100.

[0046] After storing the materials and equipment, the transport device 100 is transported in the manner shown in the drawing. After being transported, the transport device 100 is set, for example, as follows.

[0047] Fig. 2 is a diagram showing an example in which the side portion is moved upward in the height direction. Compared to Fig. 1, Fig. 2 differs in that one of the four meshes ME is moved upward in the Z-axis direction.

[0048] In this way, the mesh ME is a mechanism that can move up and down in the Z-axis direction. Specifically, the mesh ME is a mechanism that slides in the Z-axis direction. In addition, the mesh ME is a mechanism that can be moved upward and then fixed in the position after the movement.

[0049] In the state shown in Fig. 2, the mesh ME has moved upward to form an opening OP, which allows materials and equipment to be removed from the opening OP or to be stored in the space SP.

[0050] Moreover, by moving the mesh ME upward, the mesh ME becomes a handrail HR. Specifically, as shown in Fig. 2(A), when a worker MN uses the conveying device 100 as a scaffold (which is an "erecting passage," "scaffold," "work floor," or "steel pipe scaffold" in the Industrial Safety and Health Regulations. Hereinafter, simply referred to as "scaffold") at a position where work is performed on a high place such as a ceiling (a so-called work location. The work location is assumed to be determined in advance by a plan, etc.), the mesh ME moves upward.

[0051] In this way, materials and equipment can be transported to the work site.

[0052] Furthermore, at the work site, the transport device 100 can be used as a foothold. Since the mesh ME serves as a handrail HR (in FIG. 2(A), if other mesh MEs are also moved upward, they can surround the ceiling), it is possible to prevent the worker MN from falling.

[0053] In this way, the transport device 100 has a ceiling portion so that workers can ride on it, and is configured to be able to transport materials and equipment to a work site and also to be used as a scaffold at the work site.

[0054] Therefore, when the transport device 100 is used, the work area and the storage area for storing materials and equipment (hereinafter simply referred to as "storage area") can be arranged without being separated.

[0055] Conventionally, materials and equipment are stored in storage areas, so scaffolding cannot be installed at storage areas. Therefore, when a storage area is used, it is often necessary to transport the materials and equipment to another location before scaffolding can be installed and the work area can be completed. This often results in poor work efficiency.

[0056] On the other hand, since the transport device 100 can store materials and equipment, the location where the transport device 100 is located can be used as a storage area. Furthermore, since the transport device 100 can also serve as a scaffold, the location where the transport device 100 is located can also be used as a work location. Therefore, the location of the transport device 100 can serve as both a storage area and a work location. This reduces the amount of work required to transport materials and equipment to another location in order to set up scaffolding, improving work efficiency.

[0057] <Modification> The conveying device 100 may have the following configuration.

[0058] The mesh ME may have any shape that can prevent the stored materials and equipment from falling during transportation, and may be, for example, a net-like material.

[0059] The mesh ME may be movable in a manner other than sliding. For example, the mesh ME may rotate around the upper end of the mesh ME as an axis of rotation (rotation around the Y axis, which is a so-called pitch rotation) from a state in which the mesh ME is located downward in the Z axis (for example, the state shown in FIG. 1).

[0060] Alternatively, the mesh ME may have a mechanism that allows it to be removed from and attached to the transport device 100. Specifically, the mesh ME may have a mechanism that allows it to be attached in a lifted state so that the mesh ME is in the state shown in FIG. 2 after being removed from the state shown in FIG.

[0061] The side portion is not limited to the mesh ME. In other words, the side portion may be any member that can form a space for storing materials and equipment and that can serve as a handrail when moved upward in the height direction. Therefore, the side portion may be a plate material, a rod material, or a combination of these.

[0062] Also, the number of mesh MEs does not have to be four. That is, the side portion may be composed of four or more mesh MEs, or less than four mesh MEs. Furthermore, the side portion may be an object made up of two or more mesh MEs combined into one. That is, two or more mesh MEs may be connected so that multiple mesh MEs can be opened and closed with one opening and closing.

[0063] The mesh ME may or may not be installed on what are known as the front and rear surfaces.

[0064] In the above example, the longitudinal direction is the transport direction, but the longitudinal direction does not always have to be the transport direction. That is, the transport device 100 may transport in a direction other than the longitudinal direction.

[0065] Moreover, the ceiling board PL may be a single board material, or a combination of multiple board materials.

[0066] It is desirable that the transport device 100 is configured to satisfy the Temporary Equipment Certification Standards (hereinafter simply referred to as "Temporary Equipment Certification Standards") established by the Temporary Construction Industry Association. Specifically, to be used as scaffolding at construction sites, etc., a mobile indoor scaffold, an elevated work platform, or an aluminum alloy portable work platform, etc., must satisfy the requirements, etc., established in the Temporary Equipment Certification Standards in order to ensure safety.

[0067] That is, conventional containers etc. often cannot be used as scaffolding at construction sites etc. On the other hand, the transport device 100 that meets the temporary equipment certification standards can transport materials and equipment at construction sites etc. and can also be used as scaffolding.

[0068] Similarly, it is desirable that the ceiling be constructed in a manner that satisfies the standards for metal scaffolding boards or beams, etc., as specified in the temporary equipment certification standards.

[0069] Furthermore, it is desirable for the handrail HR to be configured to meet the standards of the temporary equipment certification standards, such as a leading handrail for wedge-fastened scaffolding, a handrail frame for framed scaffolding, a handrail and middle rail for wedge-type scaffolding, or a handrail frame for staircase openings.

[0070] If the composition satisfies the above-mentioned temporary equipment certification standards, it will be compatible with the materials and accessories for steel pipe scaffolding stipulated in Article 42 of the Industrial Safety and Health Act, Article 13 of the Enforcement Order of the Industrial Safety and Health Act, and Appendix 8 of the Enforcement Order of the Industrial Safety and Health Act, and therefore can be installed at construction sites, etc.

[0071] Therefore, it is desirable that the materials and structure of the ceiling meet the requirements for materials, standards, quality, wall thickness, structure, dimensions, etc. stipulated in Part 2, Chapter 10, Section 2, Articles 559 to 563 and Articles 570 to 573 of the Industrial Safety and Health Regulations.

[0072] In addition, it is desirable for the handrail HR to be at least 850 mm high from the ceiling, such as 900 mm in the example of Figure 2 (A). If the handrail HR is at such a high level, it will be a handrail that satisfies Part 2, Chapter 10, Section 2, Article 552, Paragraph 1, Item 4 (a) of the Industrial Safety and Health Regulations.

[0073] In this manner, the conveying device 100 can prevent the worker MN from falling by using the handrail HR.

[0074] The height of the conveying device 100 from the floor surface GD is preferably "less than 2000 millimeters." In order to assemble a scaffolding structure with a height of "2 meters or more," there may be an obligation to take measures under, for example, Article 564, Chapter 10, Section 2, Part 2 of the Industrial Safety and Health Regulations. Therefore, if the height of the conveying device 100 from the floor surface GD is "less than 2000 millimeters," it is easy to install it. On the other hand, it is preferable that the conveying device 100 has a certain height as a scaffolding to work on high places such as ceilings. Therefore, it is preferable that the height of the conveying device 100 from the floor surface GD is "1500 millimeters or more."

[0075] Thus, with a height of 1500 mm or more and less than 2000 mm, the transport device 100 can serve as a foothold when working at high places, and can be easily installed.

[0076] In addition, it is desirable for the conveying device 100 to have a length of "4000 millimeters or more" in the conveying direction, such as "4200 millimeters" shown in FIG. 1(A). For example, at a construction site, fixed-length materials such as beams or girders are "4 meters," "5 meters," "6 meters," etc. Therefore, it is desirable for the conveying device 100 to have a length of "4000 millimeters or more" so that fixed-length materials can be stored. It is also desirable for the space SP of the conveying device 100 to have a certain amount of leeway in length in order to store fixed-length materials. Therefore, if the conveying device 100 has a length such as "4200 millimeters," it will be able to store fixed-length materials.

[0077] Moreover, it is preferable that the conveying device 100 has a width in the orthogonal direction of 900 mm to 1000 mm, such as 900 mm shown in FIG. 1(B).

[0078] The conveying device 100 is often transported to a construction site or the like by a truck or the like. The width of the truck bed is often about 2 meters. If the width of the conveying device 100 is 900 mm to 1000 mm, it is easy to load multiple units onto the bed of a truck or the like.

[0079] Moreover, it is preferable that the transport device 100 further includes a ladder LA for assisting boarding onto the ceiling. For example, the transport device 100 has the following configuration.

[0080] 3 is a diagram showing an example of a transport device equipped with a ladder, which will be described below with reference to a side view of the transport device 100 (similar to FIG. 1(A) and the like).

[0081] As shown in the figure, the transport device 100 is provided with a ladder LA, for example, on the side. With the ladder LA, it becomes easy for the worker MN to get on top of the ceiling.

[0082] The conveying device 100 is often about 2000 mm high to perform work on high places such as ceilings. Therefore, it is difficult for the worker MN to get on the ceiling unless there is equipment such as a ladder LA to assist in getting on.

[0083] Therefore, as shown in the figure, if a ladder LA is provided, the worker MN can easily get on the ceiling. In particular, if the ladder LA is integrated, the work of setting up the ladder LA can be reduced, making the work more efficient. However, the ladder LA may be configured to be attached later.

[0084] The shape, installation position, and number of the ladders LA are not limited to those shown in the figure. That is, the ladders LA may be installed on the front or back surface, which is not a side surface. Also, multiple ladders LA may be installed.

[0085] For example, if the ladder LA is installed at a position such as the front surface (the surface shown in FIG. 1(B)) or the rear surface, the transport device 100 is unlikely to tip over even if a moment is generated near the ladder LA based on the weight of the worker MN when the worker MN uses the ladder LA to get on or off the ceiling. Therefore, it is preferable to install the ladder LA on the short side, such as the front surface or the rear surface.

[0086] The transport apparatus 100 is preferably used in combination with an operating apparatus, for example as follows.

[0087] FIG. 4 is a diagram showing an example of using an operating device. For example, it is desirable that the conveying device 100 is moved to a predetermined position by an AGV (Automated Guided Vehicle, hereinafter referred to as "AGV 101"), which is an example of an operating device. In this manner, a conveying system having the AGV 101, which is an example of an operating device, and the conveying device 100 may be configured. The conveying system may further have one or more information processing devices. For example, in the conveying system, the AGV 101 and the information processing device are connected via a network. Specifically, the conveying system may use an information processing system 10, a server 11, an information processing terminal, or a combination thereof, as shown in FIG. 8, which will be described later.

[0088] With this configuration, it is possible to provide a transport device on which a worker MN can ride, and the transport device 100 can automatically transport the worker MN after work is completed, for example, at night.

[0089] The AGV 101 is a hardware configuration that includes an actuator for moving the conveying device 100, a sensor for measuring the current position of the AGV 101, a communication device for communicating with other external devices, an interface for inputting a destination, a power source, and a control device for controlling each piece of hardware.

[0090] The AGV 101 is not limited to the hardware configuration described above. That is, the AGV 101 may be any device that can move the conveyance device 100. The AGV 101 does not have to be a single device. That is, the AGV 101 may be a device that moves one conveyance device 100 using multiple devices, or the AGV 101 may be configured to connect an information processing device or the like internally or externally.

[0091] For example, the AGV 101 moves the transport device 100 as follows.

[0092] 5 is a diagram showing an example in which the operating device moves the transport device. Hereinafter, it is assumed that the transport device 100 is placed at an initial position P1. An installation position P2 is input in advance to the AGV 101. Below, an example will be described in which the initial position P1 is the "first floor" and the installation position P2 is the "second floor", that is, the initial position P1 and the installation position P2 are on different floors.

[0093] In this example, the AGV 101 first moves the conveyance device 100 from an initial position P1 to the elevator EV. Then, the conveyance device 100 is lifted from the "1st floor" to the "2nd floor" by the elevator EV. Then, after being lifted to the "2nd floor" by the elevator EV, the AGV 101 moves the conveyance device 100 to an installation position P2.

[0094] In this way, when the conveying device 100 is installed at a predetermined position by the AGV 101, the conveying device 100 can be installed at a work site or the like, for example, during nighttime when no work is being performed. Therefore, the workload of installing the conveying device 100 can be reduced.

[0095] In addition, it is preferable that the AGV 101 can use an elevator EV or the like. If the conveyance device 100 can be moved using an elevator EV or the like in this way, the AGV 101 can be shared among a plurality of floors without installing an AGV 101 on each floor. In other words, the number of AGVs 101 can be reduced.

[0096] In addition, it is desirable that the transport device 100 and the AGV 101 can be separated as follows.

[0097] 6 is a diagram showing an example of separation of a conveying device and an operating device. For example, after the conveying device 100 is installed at the installation position P2, it is preferable that the AGV 101 is separated from the conveying device 100 as shown in the figure. In this way, when the conveying device 100 and the AGV 101 can be separated, the AGV 101 can also move other conveying devices 100.

[0098] On the other hand, the conveying device 100 may be a hardware configuration including a sensor, a communication device, an interface, and a control device. That is, the conveying device 100 may have a function of an AGV. The conveying device 100 may be configured to move on its own under the control of a control device by driving the wheels of the conveying device 100 with an actuator using the function of an AGV.

[0099] By using such an AGV 101, for example, the transport device 100 can be set up as follows.

[0100] FIG. 7 is a diagram showing an example of automatic transportation. In this example, first, the transport device 100 is transported to a construction site by a truck 21. After that, the transport device 100 is unloaded from the truck 21 by a forklift 20. Next, the transport device 100 is placed near the elevator EV by the forklift 20. This position becomes the initial position P1 in FIG. 5. That is, when the AGV 101 is prepared in advance at the initial position P1, the transport device 100 is lifted from the initial position P1 to another floor by the AGV 101 and the elevator EV as shown in FIG. 5. Then, after the transport device 100 and the AGV 101 are lifted by the elevator EV to the floor of the installation position P2, the transport device 100 is moved to the position of the installation position P2.

[0101] In this way, it is desirable for the conveying device 100 to automatically convey the work. However, instead of conveying the work entirely automatically, as in this example, some of the work may be conveyed by the forklift 20 or a worker MN.

[0102] In carrying out the above-described automatic transport, for example, an information processing system as described below may be used.

[0103] FIG. 8 is a diagram illustrating an example of management by the information processing system.

[0104] By using BIM (Building Information Modeling) data to match 3D CAD data with design information or attribute information for each model, the information processing system 10 can determine which floor a model is on from several models. In addition, the name of the area, etc. can be read from the attribute information, etc. and displayed.

[0105] Therefore, when the drawing data input procedure is performed, the information processing system 10 displays the drawing. Specifically, the information processing system 10 can display the building by the drawing and display the fixed beacons, the mobile beacons, and the like in correspondence with the drawing.

[0106] The information processing system 10 manages the transport device 100 and the like. That is, the information processing system 10 maps the transport device 100 and controls the movement of the transport device 100 to the installation position P2.

[0107] For example, the information processing system 10 has information processing devices such as a server 11, a first information processing terminal 102, and a second information processing terminal 103. The server 11, the first information processing terminal 102, and the second information processing terminal 103 are connected by wire or wirelessly, and can transmit and receive data to and from each other. Therefore, in the information processing system 10, the processing results by the server 11 are output to the first information processing terminal 102, the second information processing terminal 103, etc., and the processing results can be viewed at each base or field office, etc. Furthermore, the server 11 can accept operations by inputting operations to the first information processing terminal 102, the second information processing terminal 103, etc.

[0108] The information processing system 10 is not limited to the configuration shown in the figure. That is, the information processing system 10 may have one information processing device, or may have two or more information processing devices. The following description will be given taking the configuration shown in the figure as an example.

[0109] First, at the construction site, a transmitter that transmits a beacon signal is installed on the transport device 100. Furthermore, transmitters are also installed on pillars and the like at the construction site. Hereinafter, the transmitter installed on the transport device 100 may be referred to as a "mobile beacon 121." When the transport device 100 moves, the mobile beacon 121 moves together with the transport device 100, and so its position changes. In other words, the mobile beacon 121 is a sensor and communication device that notifies the current position of the transport device 100. Hereinafter, the position of the mobile beacon 121 is assumed to be the same as the position of the transport device 100.

[0110] On the other hand, a transmitter is installed on a pillar or the like at a construction site, and in principle, its position is fixed. Hereinafter, a transmitter installed on a pillar or the like at a construction site may be referred to as a "fixed beacon 122." Therefore, the position of the fixed beacon 122 is fixed at a position that is installed in advance.

[0111] Also, in this example, at the construction site, it is assumed that the field worker 201 and the field worker 202 have a mobile terminal 104 such as a smartphone, a tablet, or a notebook PC (Personal Computer). Hereinafter, it is assumed that the mobile terminal 104 is a receiver that receives signals from each transmitter. Then, the receiver transmits the contents indicated by the signals from each transmitter, that is, data that can identify the respective positions of each transmitter (hereinafter referred to as "positioning data"), to the information processing system 10. Note that the timing at which the various data are transmitted may be at preset cycles or may be irregular.

[0112] With such positioning data, the AGV 101 can grasp the current position, etc. Therefore, by using map data of the construction site, the AGV 101 can grasp how to move the conveyance device 100 from the difference between the current position and the installation position P2.

[0113] The information processing system 10 may have an information processing device and a sensor other than those shown in the figure.

[0114] Furthermore, the transport device 100 may be used, for example, by being connected as follows.

[0115] 9 is a diagram showing a first example of connecting a plurality of conveyance devices. First, as shown in FIG. 9(A), it is assumed that two or more conveyance devices 100 are installed at an installation position P2 by an AGV 101 or the like.

[0116] As shown in FIG. 9(B), for example, a plurality of conveying devices 100 may be used by being connected together by a connecting plate 300 or the like, which is an example of a connecting portion.

[0117] The connecting plate 300 is preferably configured to be movable so that it can be stored in the transport device 100, as shown in Fig. 9(B). The connecting plate 300 is preferably configured so that a worker MN can ride on the connecting plate 300 when the transport device 100 is connected, as shown in Fig. 9(B). In this way, if the transport devices 100 can be connected and used, high places such as ceilings can be widely used as work targets.

[0118] It should be noted that the conveying apparatus 100 may be used by connecting three or more conveying apparatuses 100 together using the connecting plate 300, for example, as follows.

[0119] Fig. 10 is a diagram showing a second example of connecting a plurality of transport devices. The illustrated example shows a case where two transport devices 100 connected as shown in Fig. 9(B) are combined into one set, and three sets are connected in the Y-axis direction (the longitudinal direction of the transport devices 100 in the drawing).

[0120] It should be noted that two or three or more sets of conveying devices 100 may be connected together. Furthermore, the direction of connection is not limited to the Y-axis direction, and may be the X-axis direction.

[0121] Alternatively, the transport device 100 may be coupled as follows.

[0122] Fig. 11 is a diagram showing a third example of connecting multiple transport devices. For example, as shown in Fig. 11(A), three transport devices 100 may be connected in the Y-axis direction by an AGV 101 or the like. In this example, the connecting parts are connecting members or the like that connect the respective transport devices 100. When connected by connecting members in this way, it is possible to prevent the transport devices 100 from being separated from each other when used as a scaffold.

[0123] As shown in Fig. 11(B), at the installation position P2, the mesh ME is moved upward in the height direction to form a handrail HR. In this way, even when used in a linked configuration, if a handrail HR is provided, it can be used as a scaffold for working at high altitudes.

[0124] Note that the conveying apparatus 100 may be used by connecting a plurality of conveying apparatuses 100 together as follows, for example.

[0125] 12 is a diagram showing a fourth example of connecting multiple conveyance devices. As shown in the figure, four conveyance devices 100 may be connected in the X-axis direction (the short side direction of the conveyance devices 100 in the figure). In the case of such a connection, only the outermost mesh may be the handrail HR.

[0126] 13 is a diagram showing a fifth example of connecting multiple conveying devices. As shown in the figure, four conveying devices 100 may be connected in pairs in the X-axis direction and the Y-axis direction (the short-side direction and long-side direction of the conveying devices 100 in the figure). In the case of such a connection, only the outermost mesh may be the handrail HR.

[0127] It should be noted that more than the number of conveying devices 100 used in the above example may be connected together for use.

[0128] The transport device 100 may also be fixed at the installation position P2.

[0129] As described above, when the conveying device 100 is used in conjunction with other devices, work can be carried out efficiently over a wide area.

[0130] For example, after work is finished at night, the transport device 100 may be automatically transported by the AGV 101. Specifically, the transport system performs, for example, the following transport method.

[0131] FIG. 14 is a diagram showing an example of a transport method.

[0132] In step S1, the transport system inputs the storage of the equipment and the predetermined position. That is, in step S1, preparation for transport is performed. That is, the transport device 100 stores the equipment. Furthermore, the AGV 101 inputs the predetermined position.

[0133] In step S2, the transport system performs a transport process to transport the transport device 100 to a predetermined position. For example, the transport process is performed after the work is completed, i.e., at night. The predetermined position is a position inputted in step S1 using a map or the like, and is a position that will be the work site for the next work. Therefore, when the transport process is performed, the materials and equipment stored in step S1 are transported to the predetermined position.

[0134] In addition, it is preferable that the conveying process conveys the conveying device 100 to a predetermined position corresponding to the equipment. In such a case, in step S1 or the like, the equipment is associated in advance with which work location it is used. Then, the AGV 101 determines, by a sensor or the like, what type of equipment is stored. In this way, the AGV 101 can determine the position to which the conveying device 100 is conveyed depending on the type of equipment.

[0135] For example, a combination of a blower and a duct connected to the blower is installed in the same place. That is, various types of equipment and materials are used in the same work area. In this way, when the combination of equipment and materials to be used in the same work area is determined, the transport position for the combination may be input.

[0136] Further, a work location where equipment or a combination of equipment is used is input in advance in the form of position information, etc. In this manner, a correspondence step of corresponding a predetermined position to equipment or materials may be performed.

[0137] Therefore, when a predetermined position is determined in accordance with the equipment or materials, for example, the task of repeatedly inputting the same information to a plurality of transport devices 100 can be omitted.

[0138] Alternatively, an RFID (radio frequency identifier) ​​or the like may be used. First, an IC tag is attached to each equipment in advance. Then, the position where each equipment is to be placed is stored in the IC tag. By storing the position in advance in the IC tag in this way, the position where the equipment with the IC tag attached is to be placed can be known by reading the IC tag. In this way, the IC tag may be attached and read to determine the position to which the transport device 100 is to be transported.

[0139] Alternatively, RFID may be used as follows:

[0140] First, information such as the location to which the transport device 100 is transported, the type of equipment and materials to be stored in the transport device 100 (i.e., equipment and materials to be used for work performed at the location to which the transport device 100 is transported), and the number of equipment and materials is registered in an IC tag in advance for each transport device 100 or each AGV 101. Then, the IC tag with the registered information may be installed on the transport device 100 or the AGV 101.

[0141] With this configuration, when storing materials and equipment, by reading the IC tag, information on the materials and equipment to be stored in each transport device 100 can be obtained. Also, an IC tag on which information such as the type of material and equipment is registered may be attached to each material and equipment, and a sensor provided on the AGV 101 or the transport device 100 may read the IC tag to check whether the necessary materials and equipment are stored.

[0142] When the transport system uses a plurality of transport devices 100, the plurality of transport devices 100 may be connected as shown in Fig. 9 to Fig. 13. In this manner, when a plurality of transport devices 100 are used, it is preferable to perform steps S3 and S4.

[0143] In step S3, the transport system judges whether or not to couple. If to couple (YES in step S3), the transport system proceeds to step S4. On the other hand, if not to couple (NO in step S3), the transport system proceeds to step S5. Note that the transport method may omit step S3 and the like, assuming that coupling is performed or not performed.

[0144] In step S4, the transport system performs a connecting process to connect the ceiling parts. For example, the connecting process is performed as shown in Fig. 9. Therefore, when the connecting process is performed, the multiple transport devices 100 are connected and reach the state shown in Figs. 9 to 13. In this way, when the connecting process is performed, the transport devices 100 are connected, and the worker MN can secure a wide foothold.

[0145] In step S5, the conveying system performs a moving process to move the side portion. That is, the conveying system moves the mesh ME upward. Therefore, when the moving process is performed, the conveying device 100 changes from the state shown in FIG. 1 to the state shown in FIG. 2.

[0146] In step S6, the transport system performs an unloading process for unloading the materials and equipment. For example, in the unloading process, the stored materials and equipment are made ready for use. Therefore, in the unloading process, a state in which the opening OP is secured is maintained by a moving process or the like. Note that in the unloading process, the materials and equipment may be moved out of the transport device 100 by an actuator or the like.

[0147] In step S7, the transportation system performs a boarding process to have a worker board the ceiling. Work by the worker MN is performed at a work location that is set in advance. Therefore, when the transportation device 100 is fixed at the work location, i.e., the predetermined position input in step S1, the worker MN can board the ceiling and perform work at a high place, as shown in FIG. 2. Therefore, the boarding process includes fixing the transportation device 100 to the work location, etc.

[0148] Then, during the day, the worker MN performs construction work using the materials and equipment transported by the automatic transport process and the transport device 100, etc. Then, for the next construction work, the next installation position, etc. are input to the AGV 101, etc. Then, after the work is completed, step S8 is performed.

[0149] In step S8, the transport system performs an unloading process to unload the equipment and materials. For example, the equipment and materials to be unloaded are stored in the transport device 100 by the worker MN. Then, when the worker MN performs a predetermined operation (e.g., pressing a button), the transport device 100 starts unloading.

[0150] The conveying device 100 may start to unload the workpiece 100 based on time, an operation, or a combination thereof.

[0151] For example, after finishing the work, the worker MN performs an operation indicating the end of the work (for example, pressing a button, etc.). Next, after a predetermined time during which the worker MN can leave (for example, one hour or more, the time is set in advance, for example), the worker MN may be automatically taken out.

[0152] Alternatively, first, a predetermined time, which is any time after the end of work (a time after a predetermined time has elapsed when the worker MN can leave after the end of work. For example, if the work is performed during the day, the time refers to nighttime) is set in advance in the work plan. Then, the conveying device 100 may be automatically discharged at the predetermined time.

[0153] When the above-mentioned transport method is performed, a transport device that a worker can ride on can be provided to the work site. Also, when each process in the transport method is performed by the transport system, a transport device that a worker can ride on can be provided to the work site without operation by the worker MN or the like.

[0154] The transport process, etc. may be performed not only at night but also during the time when the workers MN, etc. are working. In particular, when the transport process, etc. is performed after the work is completed, the materials and equipment can be transported to the work site without the workers MN having to operate it, thereby reducing the burden on the workers MN.

[0155] The transport method is not limited to a method in which the processes are performed at the timings shown above, and in the order of the processes shown in the figure. For example, step S1, etc. may be performed after the work is completed. Furthermore, step S4 and step S5 may be performed in parallel. In this way, some or all of the processes may be performed in parallel or redundantly. The transport method may also include a process performed by a worker MN, etc.

[0156] <Second embodiment> 15 is a diagram showing an example of the appearance of the transport device of the second embodiment. In the following diagrams, the short side direction of one side of the transport device 100 is the X-axis (also called the "horizontal direction"), and the long side direction of the transport device 100 is the Y-axis (also called the "depth direction").

[0157] For example, two or more transport devices 100 as shown in the figure are connected together to form a scaffold. Specifically, the transport device 100 has the following dimensions and shape.

[0158] Fig. 16 is a diagram showing an example of the dimensions and shape of a conveying device. Specifically, Fig. 16(A) is a so-called side view (shown on the YZ axis plane), mainly showing the side portion. As shown in the figure, the side portion is composed of, for example, multiple side plate PT. And, the state shown in Fig. 16(A) is a state in which some of the side plate PT have moved upward in the height direction.

[0159] FIG. 16(B) is a so-called top view (shown on the XY-axis plane), showing a state in which mainly the ceiling and side surfaces are used as scaffolding materials.

[0160] Fig. 16(C) is a so-called front view (shown on the XZ-axis plane), and shows the state in which mainly the ceiling and side parts are used as scaffolding. If the side shown in Fig. 16(A) is the flat side, the side shown in Fig. 16(C) is the gable side.

[0161] 16(D) and 16(E) are examples of structures for fixing the side plate PT. For example, if a structure using a latch stopper as shown in the figures is used, the side plate PT can be fixed at a predetermined height.

[0162] With a configuration including the side panel PT as shown in the figure, for example, as in the first embodiment, while the transport device 100 is transporting materials and equipment, the side panel PT can contain the materials and equipment within the transport device 100. When a worker MN boards on the ceiling, for example, as in the first embodiment, the side panel PT can be moved upward in the height direction to serve as a handrail, and the temporary equipment certification standards can be met.

[0163] Furthermore, when a plurality of transport devices 100 are connected to each other, the side panels PT are used to realize the connections and the scaffolding. Specifically, the connections and the scaffolding are realized by the following connection method.

[0164] <Example of how to connect the transport device> FIG. 17 is a diagram showing an example of a method for connecting the transport device.

[0165] In step S21, the conveyance system or the like conveys the conveyance device 100. That is, the conveyance device 100 is conveyed to a work location in step S21. Hereinafter, it is assumed that a plurality of conveyance devices 100 are conveyed in step S21.

[0166] In step S22, it is determined whether the side surface portion is to be a scaffolding material or a handrail. That is, it is determined for each side surface portion whether it is to be a scaffolding material or a handrail, and it is possible to select which for each side surface portion.

[0167] If the side surface is to be used as a scaffolding material (step S22: "scaffolding material"), the process proceeds to step S24. On the other hand, if the side surface is to be used as a handrail (step S22: "handrail"), the process proceeds to step S23.

[0168] In step S23, the side surface portion is moved upward in the height direction and, after the movement, is fixed.

[0169] In step S24, the side plate PT is used to connect with another transport device and become a scaffolding material. Specifically, the side plate PT is operated as follows.

[0170] Figure 18 is a diagram (part 1) showing an example of connecting transport devices using the side sections to create scaffolding. First, as shown in the figure, the side panel PT is slid to the height at which the scaffolding material is to be constructed. The example shown is one in which the scaffolding material is installed at the same height as the ceiling. After this, the side panel PT is tilted around the Y axis (in the figure, it is rotated towards the front), resulting in the following state.

[0171] Fig. 19 is a diagram (part 2) showing an example of connecting transport devices using the side parts to create scaffolding. As shown in the figure, the side panel PT is rotated about 90° around the Y axis from the state shown in Fig. 18. In this way, the transport devices can be connected using the side panel PT, and the scaffolding can be constructed. Specifically, the transport devices can be connected and the scaffolding can be constructed as follows.

[0172] Fig. 20 is a diagram (part 3) showing an example of connecting transport devices using side parts to create a scaffold. The illustrated example is an example after connecting two transport devices using the connecting method shown in Fig. 17. When multiple transport devices 100 are connected as shown in the figure, a worker MN can use them, for example, as follows.

[0173] Fig. 21 is a diagram (part 4) showing an example of connecting transport devices using the side parts to create a scaffold. Specifically, the illustrated example shows a case where four transport devices 100 are connected. When the transport devices 100 are connected in this way, a scaffold for working at high places can be constructed by the ceiling parts and the connecting parts.

[0174] On the other hand, the side panels PT that do not form a connecting portion and are located on the outer periphery, etc., can be used as handrails HR.

[0175] <Details of the connection part> The connecting portion CN is formed, for example, by combining a side panel PT and a ceiling CE having the following shape.

[0176] Fig. 22 is a diagram showing the details of the connection part. The figure is an enlarged view of the part (hereinafter referred to as the "tip part PTL") where the side panel PT and the ceiling CE come into contact when they are connected in the scene where they are connected as in Fig. 20. The example shown in the figure is an example of a configuration in which the tip part PTL overlaps the end of the ceiling CE, and the side panel PT sits on top of the ceiling CE.

[0177] It is desirable that the tip PTL of the side panel PT, i.e., the portion where it contacts the ceiling CE of another transport device, is "L" shaped or the like. In this way, when one of the portions constituting the connecting portion is "L" shaped, the step in forming the connecting portion can be made smaller. In this example, the step is a protrusion (in the figure, it is the difference in height in the upward direction on the Z axis based on the height of the ceiling CE) that occurs at the portion where the side panel PT and the ceiling CE overlap. If such a step is large, the worker MN is likely to trip over the step, which may cause an accident. Therefore, if the tip PTL is "L" shaped as shown in the figure, the step can be made smaller, and the number of situations in which the worker MN or the like trips over the step can be reduced.

[0178] In addition, the side panel PT is configured to be supported at a location other than the tip portion PTL. Specifically, it is supported by a support material SU. For example, it is desirable for the support material SU to be composed of furring strips and an elastic body such as rubber. Using an elastic body can soften the impact that occurs when connecting the pieces.

[0179] The support material SU is shaped to protrude outward.

[0180] The support material SU supports the parts of the side plate PT other than the tip part PTL, i.e., the parts of the side plate PT that have thickness, in the X-axis direction of the connection (left and right direction in FIG. 22). Specifically, the support material SU is installed at a position that supports the side plate PT between the center of the side plate PT and the tip part PTL in the X-axis direction of the connection.

[0181] In addition, the support material SU is installed at a height such that the side plate PT and the ceiling part of the other transport device are flat when connected. That is, the support material SU is installed at a height adjusted so that there is no step when the side plate PT and the ceiling part of the other transport device are connected. On the other hand, it is preferable that the support material SU is adjusted to a height such that the side plate PT is supported and the side plate PT is not supported by only the tip part PTL and the ceiling part.

[0182] Since the tip part PTL may be processed to be thin, it is often not as strong as other parts of the structure. Therefore, it is preferable that the support material SU mainly supports the side panel PT, not the tip part PTL and the ceiling part.

[0183] In this way, the side panel PT is also supported by the supporting material SU, that is, when the side panel PT is supported at multiple points, it becomes a scaffolding material and can support the weight of the worker MN in a distributed manner.

[0184] The side panels PT (including the tip portions PTL) and the ceiling CE are made of a practical metal such as aluminum.

[0185] <Third embodiment> In the third embodiment, when multiple transport devices 100 are connected, the transport devices 100 are connected at different heights and are configured to serve as a scaffolding material on which workers stand. Specifically, by connecting multiple transport devices 100, a scaffolding material can be formed at the following height (hereinafter referred to as a "second height H2") in addition to the height shown in the second embodiment (hereinafter referred to as a "first height H1").

[0186] FIG. 23 is a diagram showing an example of connection at the second height.

[0187] The first height H1 is, for example, 1950 mm, and the second height H2 is, for example, 900 mm.

[0188] The first height H1 is, for example, a height used for facility construction work. Meanwhile, the second height H2 is a height used for building construction work. In this way, if multiple heights can be set according to the construction work, the work of replacing the conveying device for each construction work can be reduced.

[0189] The switching between the first height H1 and the second height H2 is realized by a mechanism for sliding the side panel PT in the Z-axis direction, etc. Such a sliding mechanism can prevent the side panel PT from being removed and lost.

[0190] Further, the scaffolding other than the side panel PT is formed, for example, as follows.

[0191] Fig. 24 is a diagram showing an example of the formation of a scaffolding. Note that the portion shown in the figure (hereinafter referred to as "enlarged portion 200") is an enlarged portion of the angle bar PT2 etc. in Fig. 28(A).

[0192] For example, a scaffold is formed by fitting a scaffolding board PT1 into an angle bar PT2. Specifically, a pin of the scaffolding board PT1 is fitted into a hole formed in the angle bar PT2 to form the scaffold.

[0193] With the above configuration, for example, a scaffolding as shown below can be constructed at the second height H2.

[0194] Fig. 25 is a diagram showing an example of connecting the transport devices using the side parts to create a scaffold in the third embodiment. Specifically, the example shown in Fig. 25(A) and Fig. 25(B) is an example of connecting four transport devices 100, similar to Fig. 21. When the transport devices 100 are connected in this way, a scaffold for work can be constructed by the scaffold boards and the connecting parts.

[0195] Fig. 26 is a diagram showing an example of a movement line. For example, in the configuration shown in Fig. 25, the movement line of the worker MN is possible as shown in Fig. 26 (in the figure, the places where the worker MN can move are shown by arrows). In this way, a scaffold for the worker MN can be constructed at the second height H2.

[0196] <Example of how to connect> FIG. 27 is a diagram showing an example of a connection method.

[0197] In step S31, the conveying system conveys the conveying device 100 in the same manner as in step S21, for example. That is, the conveying device 100 is conveyed to a work location in step S31. Hereinafter, it is assumed that a plurality of conveying devices 100 are conveyed in step S31.

[0198] In step S32, it is determined whether the height at which the side portion is to be constructed as the scaffolding is the first height or the second height. That is, in this example, the height can be selected from two types, the first height and the second height.

[0199] If the first height is to be selected ("first height" in step S32), the process proceeds to step S33. On the other hand, if the second height is to be selected ("second height" in step S32), the process proceeds to step S34.

[0200] In step S33, the side portion is set to a first height and is then moved and used for connection.

[0201] In step S34, the side portion is set to a second height and is used for connection after movement.

[0202] In this manner, the scaffolding material is formed by connecting the transport device to the side at the height selected in the judgment procedure such as step S32.

[0203] <Modification> Fig. 28 is a diagram showing a modified example of the conveying device. For example, the conveying device 100 may be used in a configuration as shown in Fig. 28(A), a configuration as shown in Fig. 28(B), or a combination of the conveying devices shown in Fig. 28(A) and Fig. 28(B).

[0204] The conveying device 100 shown in FIG. 28(A) and FIG. 28(B) differs in the configuration of the outer frame (hereinafter referred to as "outer frame 111") that supports the storage space, the ceiling, etc. Specifically, in the example shown in FIG. 28(A), the outer frame 111 is composed of two pillars. In this configuration, the support pillar and the slide rail (used for sliding the side panel and has a U-shaped cross section) are separate. On the other hand, in the example shown in FIG. 28(B), the outer frame 111 is composed of one pillar. In this configuration, the pillar serves as both the support pillar and the slide rail. And, with the configuration shown in FIG. 28(B), the dimension in the X-axis direction can be reduced. For example, the dimension in the X-axis direction can be reduced to about 1060 mm.

[0205] In this way, since the conveying device 100 is small with a side dimension of 1060 mm or less, multiple conveying devices 100 can be mounted on a truck or the like, so that four units can be mounted on a 10-ton truck or two units can be mounted on a 4-ton truck.

[0206] As shown in FIG. 28(B), the support material may have a shape obtained by partially removing the shape shown in FIG. 28(A).

[0207] Furthermore, by positioning the support and the knee brace at different positions in the Y-axis direction, the dimension in the X-axis direction can be reduced.

[0208] In Fig. 28(B), in order to reduce the dimension in the width direction, the support posts (which also serve as slide rails) are positioned closer to the inside than in Fig. 28(A). This configuration, i.e., a configuration in which scaffolding boards of the same dimensions can be used between Fig. 28(A) and Fig. 28(B), is desirable. For example, as shown in Fig. 28(B), the ceiling CE may be placed on a frame (i.e., the 21st horizontal bar 100EH21, the 41st horizontal bar 100EH41, the 22nd horizontal bar 100EH22, and the 42nd horizontal bar 100EH42 in the example shown in Fig. 28(B)), with the angle bar PT eliminated from the configuration shown in Fig. 28(A).

[0209] The tip portion PTL may have the following shape.

[0210] Fig. 29 is a diagram showing an example of the shape of the tip part. For example, the tip part PTL may have a shape as shown in Fig. 29(A) to Fig. 29(I). Fig. 29(A) to Fig. 29(F) are enlarged views of the tip part PTL. Meanwhile, Fig. 29(G) to Fig. 29(I) are diagrams showing the entire side part including the tip part PTL.

[0211] For example, even in the shapes shown in Figures 29(A) to 29(F), the tip portion PTL (the part shown by the solid line in the figures, which is the right side) has a thinner shape and is thinner (the vertical dimension in the figures) than parts other than the tip portion PTL (the part shown by the dotted line in the figures, which is the left side). In this way, it is sufficient that all or part of the tip portion PTL has a shape that is thinner. A shape that is thinner in thickness like this can reduce the step.

[0212] Also, in order to reduce the thickness of the portion in contact with other transport devices, the side portion may be constructed by combining a plurality of parts as shown in FIGS. 29(G) to 29(I).

[0213] The step is small if the tip part PTL of the side part and the ceiling part of the other transport device with which the tip part PTL comes into contact during the connection are flat. Therefore, it is preferable to process the tip part PTL so that the connection part is as flat as possible by processing the shape of the tip part PTL, for example, by making it thin.

[0214] In particular, if the shape is "L", the step can be made smaller and the manufacturing process can be easily performed by bending or the like.

[0215] Furthermore, the tip portion PTL and the ceiling CE may be combined in a shape opposite to that shown above. That is, the ceiling CE may be in an "L" shape, or the like. Similarly, the support material SU may be provided by the side panel PT or by the ceiling CE. That is, in the example shown in FIG. 22, the support material SU is configured such that an elastic body is placed on top of the furring strips provided by the conveying device on the ceiling CE side, but the support material SU may be, for example, a structure in which the furring strips and the elastic body are integrated. Furthermore, the support material SU may be configured in a way other than a furring strip and an elastic body.

[0216] The position, shape and material of the support material SU are not limited as long as it can support the side plate PT. For example, the support material SU may be metal, wood, an elastic body, or a combination of these.

[0217] The side plate PT may be supported by the tip portion PTL and the support material SU. In other words, the side plate PT may be supported not only by the support material SU but also by the tip portion PTL and the like.

[0218] The connecting portion may also be configured as follows.

[0219] Fig. 30 is a diagram showing a first modified example of the connecting portion. For example, as shown in the figure, it is desirable to provide an angle portion C1 on the side panel PT, and a receiving portion C2 for hooking the angle portion C1 on the other ceiling CE (which will be another transport device). The receiving portion C2 may be made of a support material SU or the like. In other words, it may be configured to serve both the role of supporting the side panel and fitting with the angle portion C1. Also, the receiving portion C2 may have a shape as shown in Fig. 28(B) instead of the shape shown in the figure.

[0220] In this way, when the angle portion C1 and the receiving portion C2 are configured to fit together, the connection is unlikely to come off even if the transport device to which they are connected moves. Therefore, when the angle portion C1 and the receiving portion C2 are configured to fit together using a protruding shape, the connection can be easily maintained.

[0221] Moreover, it is preferable that the side plate PT has the following configuration.

[0222] Figure 31 is a diagram showing a second modified example of the connecting portion. As shown in Figure 31(A), it is preferable that the side plate PT is configured to include an auxiliary plate PTA. For example, the auxiliary plate PTA has a structure that slides in the Y-axis direction. If the auxiliary plate PTA can slide in this way, it can be moved to a position such as that shown in Figure 31(B), for example.

[0223] If the auxiliary plate PTA is located in the position shown in Figure 31(B), it can close the gap between the side plates PT and PT. Such a gap can cause workers MN, etc. to trip and lead to accidents. Therefore, if the auxiliary plate PTA can close the gap, it can reduce the number of situations where workers MN, etc. trip.

[0224] For example, as shown in Fig. 19, the side panel PT includes a portion that can be rotated to become a foothold, i.e., horizontal (hereinafter referred to as "horizontal portion PT10"), and a portion that remains vertical even after rotation (hereinafter referred to as "vertical portion PT11"). As shown in the figure, when comparing the length of the horizontal portion PT10 in the Y-axis direction (hereinafter referred to as "horizontal portion dimension L10") with the length of the vertical portion PT11 in the Y-axis direction (hereinafter referred to as "vertical portion dimension L11"), the vertical portion dimension L11 may be wider than the horizontal portion dimension L10. For example, when a mechanism for sliding or the like is provided, the mechanism is provided on both ends of the horizontal portion PT10, resulting in a narrower width.

[0225] In such a dimensional relationship, when the horizontal part PT10 is connected to the horizontal part PT10 of the other transport device, a gap is likely to occur at the boundary between the horizontal part PT10 and the horizontal part PT10 of the other transport device to be connected. Therefore, it is preferable to use a configuration in which the auxiliary plate PTA closes the gap that occurs at the boundary.

[0226] Gaps can cause workers to trip or fall, etc. Therefore, by sealing the gaps with the auxiliary plate PTA, accidents such as tripping can be prevented.

[0227] The other side surface may be a side surface of another transport device (that is, a transport device adjacent to the transport device via connection) or may be another side surface of the own device.

[0228] 32 is a diagram showing a modified example in which knee braces are used. As shown in the figure, it is preferable that the side plate PT has a knee brace PTB. The knee brace PTB has a built-in locking mechanism.

[0229] When connecting, the knee brace PTB is unlocked before use. When the lock is released, the side panel PT can be rotated about 90° around the Y axis, with the hinge as the fulcrum, as shown in FIG. 19. With a configuration including such a knee brace PTB, the side panel PT can be maintained in a stable state. Therefore, when used as a handrail, for example, it is unlikely to fall over even if a horizontal force is applied, ensuring safety.

[0230] Also, it is desirable that the support material SU is installed so as to avoid the knee brace PTB. With such a configuration, the width of the conveying device can be reduced. In this way, when the support material SU is installed so as to avoid the knee brace PTB, the support material SU does not have a continuous shape as shown in FIG. 30, but is configured to support the side portion at both ends of the side portion, as shown in FIG. 28(B). In such a case, it is desirable that the side portion is supported not only by the support material SU but also by the tip portion PTL so that the side portion can be supported at many points.

[0231] It is also desirable to have a handrail on the so-called gable side, as described below.

[0232] Fig. 33 is a diagram showing a modified example in which a handrail is formed on the end side. For example, the transport device desirably has a handrail member HRP as shown in Fig. 33(A).

[0233] For example, as shown in Fig. 33(B), the handrail member HRP is connected to a handrail member HRP of another transport device to form a handrail. Also, the handrail member HRP is stored on the end side of the transport device 100 (the position shown by the handrail storage section 110 in the figure) during transport, for example. The handrail member HRP may be stored in a location other than the handrail storage section 110.

[0234] When connecting, as shown in Fig. 33(C), the handrail member HRP can be spread out and connected to the handrail member HRP of another transport device to form a handrail, as shown in Fig. 33(B). In this way, a configuration in which a handrail can be formed on the gable side is desirable. If there is a handrail on the gable side, it can be used as a safer scaffolding material.

[0235] It should be noted that the height may be set to three or more different levels. The height may be changed by a mechanism other than sliding the side portion. For example, the side plate PT may be detachable from and attachable to the conveying device. Alternatively, the side plate PT may be installed separately for each height.

[0236] The connection may be achieved by a manual operation, or may be achieved by a conveying system or the like by driving a mechanism using an actuator and a control device or the like.

[0237] In addition, in the illustrated example, in order to make it easier to see, the illustration of parts and the like may be omitted. Therefore, the conveying device 100 may have a configuration including parts other than those illustrated.

[0238] It is preferable that the side parts that are not used as scaffolding can be fixed in an upright position without being removed, for example, as shown in Fig. 26. If the side parts are removed, they may be lost. Therefore, if the side parts are not used as scaffolding, for example, if they can be fixed to the transport device 100 as shown in Fig. 26, they can be prevented from being lost.

[0239] For example, the transport device 100 is realized by attaching wheels to a rectangular parallelepiped framework as shown in Figs. 15 and 28. Specifically, the framework is composed of a rod-shaped member positioned vertically along the Z-axis direction (hereinafter referred to as the "first vertical rod"; hereinafter, an example will be described based on the "first vertical rod 100EV1" in the drawings), three rod-shaped members (hereinafter referred to as the "second vertical rod", "third vertical rod" and "fourth vertical rod") that are installed parallel to the first vertical rod, i.e., positioned vertically along the Z-axis direction, and rod-shaped members that are perpendicular to the first to fourth vertical rods. For example, the first vertical rod 100EV1, the second vertical rod 100EV2, the third vertical rod 100EV3 and the fourth vertical rod 100EV4 are all vertical and are positioned at the four corners of the transport device 100.

[0240] Hereinafter, a rod-shaped member perpendicular to the first vertical rod 100EV1 to the fourth vertical rod 100EV4, i.e., a rod-shaped member positioned horizontally with respect to the XY plane, is referred to as a "horizontal rod". For example, two horizontal rods are installed between each of the first vertical rod 100EV1 to the fourth vertical rod 100EV4. Specifically, two horizontal rods (hereinafter referred to as "eleventh horizontal rod 100EH11" and "twelfth horizontal rod 100EH12") are installed between the first vertical rod 100EV1 and the second vertical rod 100EV2. That is, the eleventh horizontal rod 100EH11 and the twelfth horizontal rod 100EH12 are parallel to the X-axis and perpendicular to the first vertical rod 100EV1 and the second vertical rod 100EV2. The eleventh horizontal bar 100EH11 and the twelfth horizontal bar 100EH12 are fixed to the first vertical bar 100EV1 and the second vertical bar 100EV2 by welding, screwing, or the like. The vertical and horizontal bars are not limited to being in the shape of a bar, and may be multiple parts or plates, etc. The horizontal bars, etc. are not limited to being in a parallel relationship as shown in the figure, and may be in an intersecting relationship, etc.

[0241] Between the second vertical rod 100EV2 and the third vertical rod 100EV3, horizontal rods (hereinafter referred to as the "21st horizontal rod 100EH21" and the "22nd horizontal rod 100EH22") are installed. That is, the 21st horizontal rod 100EH21 and the 22nd horizontal rod 100EH22 are parallel to the Y-axis and perpendicular to the second vertical rod 100EV2 and the third vertical rod 100EV3. The 21st horizontal rod 100EH21 and the 22nd horizontal rod 100EH22 are fixed to the second vertical rod 100EV2 and the third vertical rod 100EV3 by welding, screwing, or the like.

[0242] Two horizontal bars (hereinafter referred to as the "thirty-first horizontal bar 100EH31" and the "thirty-second horizontal bar 100EH32") are installed between the third vertical bar 100EV3 and the fourth vertical bar 100EV4. That is, the thirty-first horizontal bar 100EH31 and the thirty-second horizontal bar 100EH32 are parallel to the X-axis and perpendicular to the third vertical bar 100EV3 and the fourth vertical bar 100EV4. The thirty-first horizontal bar 100EH31 and the thirty-second horizontal bar 100EH32 are fixed to the third vertical bar 100EV3 and the fourth vertical bar 100EV4 by welding, screws, or the like.

[0243] Two horizontal bars (hereinafter referred to as the "41st horizontal bar 100EH41" and the "42nd horizontal bar 100EH42") are installed between the fourth vertical bar 100EV4 and the first vertical bar 100EV1. That is, the 41st horizontal bar 100EH41 and the 42nd horizontal bar 100EH42 are parallel to the Y-axis and perpendicular to the fourth vertical bar 100EV4 and the first vertical bar 100EV1. The 41st horizontal bar 100EH41 and the 42nd horizontal bar 100EH42 are fixed to the fourth vertical bar 100EV4 and the first vertical bar 100EV1 by welding, screws, or the like.

[0244] In this manner, the framework is a structure including the first vertical rod 100EV1 to the fourth vertical rod 100EV4, the eleventh horizontal rod 100EH11 to the forty-second horizontal rod 100EH42, and so on.

[0245] Moreover, the side plate PT is installed, for example, between the first vertical rod 100EV1 and the fourth vertical rod 100EV4. The side plate PT has a mechanism that slides up and down along the first vertical rod 100EV1 and the fourth vertical rod 100EV4. Similarly, the side plate PT is installed, for example, between the second vertical rod 100EV2 and the third vertical rod 100EV3. In this case, the side plate PT has a mechanism that slides up and down along the second vertical rod 100EV2 and the third vertical rod 100EV3.

[0246] The number of vertical and horizontal rods and their installation positions are not limited to those shown in Figures 15 and 28. In other words, as long as the framework formed by the vertical and horizontal rods functions as storage and scaffolding, the shape and components are not limited to those shown in the drawings.

[0247] Furthermore, the numerical values ​​of the dimensions explained above are merely examples, and a person skilled in the art can appropriately adopt the dimensions depending on the use of the conveying device, etc.
