Summary of the Invention

Problems to be Solved by the Invention

[0004] Incidentally, with the recent expansion of the mail-order business, large-scale logistics warehouses need to move a large number of packages in a short time, and the transportation of packages by automatic conveyors has become indispensable. For example, in a certain logistics warehouse, hundreds of automatic conveyors are running almost non-stop throughout the year. In places with high running frequencies, the slab surface is partially damaged over time, and there are cases where damaged areas such as ruts occur. Such damaged areas will lead to damage to the automatic conveyors, malfunctions of the mounted equipment, and misoperations because the vibration and impact during the running of the automatic conveyors become large.

[0005] Such damaged areas on the slab surface are generally repaired with materials such as resin or mortar to eliminate the step with the surroundings. However, the work of visually detecting the damaged areas scattered on a large-area concrete slab is extremely laborious. In addition, since it is difficult to efficiently repair all the damaged areas spreading over a wide range within a limited time, it is necessary to prioritize the repair locations, but there is currently no effective means.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a repair location extraction device and a repair location extraction method capable of efficiently extracting damaged locations.

[0008] In the present invention, as a second solution means related to the repair location extraction device, in the above first solution means, the member extraction unit adopts a means of extracting the failure-related floor members for each of a plurality of operation periods.

[0009] In the present invention, as a third solution means related to the repair location extraction device, in the above first or second solution means, the repair location setting unit adopts a means of evaluating whether or not the cause of the failure is in the failure-related floor members by referring to an evaluation table in which the relationship between the failure content and the cause of the failure is registered.

[0010] In the present invention, as a fourth solution means related to the repair location extraction device, in any one of the above first to third solution means, the notification unit adopts a means of transmitting the floor member to be repaired to the repair work terminal.

[0011] In the present invention, as a fifth solution means related to the repair location extraction device, in any one of the above first to fourth solution means, the floor member is a concrete slab, and this means is adopted.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The repair location extraction device A according to this embodiment is a general-purpose computer equipped with a repair location extraction program (application program), and includes a communication unit 1, a storage unit 2, an operation unit 3, an arithmetic unit 4, and a display unit 5 as shown in FIG. 1.

[0016] This repair location extraction device A exhibits desired functions by communicating with a conveyance management device B and a repair work terminal C as shown in the figure. Although details will be described later, among these functional components, the arithmetic unit 4 constitutes a member extraction unit, a failure content acquisition unit, and a repair location setting unit in the present invention.

[0017] This repair location extraction device A is installed in a logistics facility such as a large-scale logistics warehouse. The logistics facility transports and stores goods by having an automatic guided vehicle (AGV) run on a transport path composed of a plurality of floor members. The above floor members are, for example, concrete slabs. Note that the automatic guided vehicle in this embodiment corresponds to the transporter of the present invention.

[0018] That is, in the logistics facility, a plurality of automatic guided vehicles run on a transport path paved with a plurality of concrete slabs as floor members. Although the concrete slab is a floor member excellent in terms of strength, it may be partially damaged due to the frequent running of the automatic guided vehicle, and damaged locations such as ruts may occur.

[0019] To explain the transport management device B first, the transport management device B is installed in the above-described logistics facility and is a device that manages the transport of goods in the logistics facility. This transport management device B, for example, manages the operations of a plurality of automatic guided vehicles that transport goods in the logistics facility, and stores the operation history of each automatic guided vehicle as operation history data b1.

[0020] The operation history data b1 includes the failure history of each automatic guided vehicle (AGV). As shown in FIG. 2, this failure history is a table in which the AGV identification number, failure content, and position number (failure position) are registered for the failed automatic guided vehicle (AGV), and the position numbers are arranged in descending order of the number of failures.

[0021] The above position No. is a management number for specifying the positions of a plurality of concrete slabs (floor members) that make up the transport path. That is, the laying positions of the plurality of concrete slabs (floor members) are specified by the position No. Such a failure history (operation history data b1) registers the position number (failure position) and the failure content for the automatic guided vehicle (AGV) that has failed during a predetermined period.

[0022] Regarding the repair location extraction device A, the communication unit 1 is communicably connected to an external transport management device B, and receives operation history data b1 from the transport management device B based on a reception instruction input from the arithmetic unit 4. The communication unit 1 outputs the operation history data b1 received from the transport management device B to the arithmetic unit 4.

[0023] Also, this communication unit 1 functions as the notification unit of the present invention. That is, the communication unit 1 transmits the repair target slab to the repair work terminal C based on a transmission instruction input from the arithmetic unit 4. This repair target slab is a concrete slab determined by the arithmetic unit 4 to require repair due to the travel of an automated guided vehicle (AGV), and is the repair target floor member of the present invention.

[0024] The storage unit 2 consists of a plurality of storage devices such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk, stores the above-described repair location extraction program, and temporarily stores the operation history data b1 (failure history) input from the arithmetic unit 4. Also, the storage unit 2 temporarily stores various data generated during the execution process of the repair location extraction program by the arithmetic unit 4. Furthermore, the storage unit 2 outputs these stored data to the arithmetic unit 4 in response to a read request from the arithmetic unit 4.

[0025] The operation unit 3 is configured by a keyboard, a mouse, etc., receives an instruction (operation instruction) from an operator, and outputs it to the arithmetic unit 4. This operation instruction is, for example, an execution start instruction for the repair location extraction program or an output instruction for the execution result of the repair location extraction program. The operator inputs his / her instruction to the repair location extraction device A by manually operating the operation unit 3.

[0026] The arithmetic unit 4 evaluates a plurality of concrete slabs (floor members) based on the operation history data b1 (failure history) by executing a repair location extraction program (application program) on a predetermined OS (Operating System: basic software). This arithmetic unit 4 outputs various data generated during the execution process of the repair location extraction program to the storage unit 2 for temporary storage. Details of the operation of the arithmetic unit 4 based on the repair location extraction program will be described later as the operation of the repair location extraction device A.

[0027] Also, this arithmetic unit 4 outputs the repair target slab (repair target floor member), which is the execution result of the repair location extraction program, to the display unit 5. Further, when an instruction to transmit the repair target slab (repair target floor member) from the operation unit 3 to the repair work terminal C is input, this arithmetic unit 4 outputs the repair target slab (repair target floor member) to the communication unit 1 to transmit it to the repair work terminal C.

[0028] The display unit 5 is, for example, a liquid crystal display device and functions as the notification unit of the present invention. This display unit 5 displays the repair target slab (repair target floor member) input from the arithmetic unit 4 as an image. The repair person in charge and the management person in charge of the concrete slab (floor member), who are related to the logistics facility, perform repair work or repair management of the repair target slab (repair target floor member) based on the repair target slab (repair target floor member) displayed as an image on the display unit 5.

[0029] The repair work terminal C is a communication terminal carried by the repair person in charge of a plurality of concrete slabs (floor members) and the management person in charge of the logistics facility. The repair person in charge and the management person in charge perform repair work or repair management of the repair target slab (repair target floor member) based on the repair target slab (repair target floor member) received by the repair work terminal C from the repair location extraction device A.

[0030] Next, the operation of the repair location extraction device A according to the present embodiment, that is, the repair location extraction method using the repair location extraction device A, will be described with reference to FIGS. 3 to 7.

[0031] In this repair location extraction device A, the arithmetic unit 4 executes a series of processes shown in FIG. 3 based on a repair location extraction program, thereby identifying a repair target slab (repair target floor member) corresponding to the operation history data b1. Below, the processing procedure of the arithmetic unit 4 based on the repair location extraction program will be described as the operation of the repair location extraction device A.

[0032] First, the arithmetic unit 4 acquires the operation history data b1 from the transport management device B (step S1). That is, when starting the execution of the repair location extraction program, the arithmetic unit 4 first outputs a request for acquiring the operation history data b1 to the communication unit 1. The communication unit 1 communicates with the transport management device B based on this acquisition request, and receives the operation history data b1 (failure history) from the transport management device B. Then, the communication unit 1 outputs the operation history data b1 received from the transport management device B to the arithmetic unit 4.

[0033] When the arithmetic unit 4 acquires the operation history data b1 in this way, it temporarily stores the operation history data b1 in the storage unit 2. That is, the arithmetic unit 4 outputs a write request for the operation history data b1 to the storage unit 2, thereby storing the operation history data b1 in the storage unit 2.

[0034] Then, the arithmetic unit 4 extracts failure-related slabs (failure-related floor members) from the failure history of the operation history data b1 (step S2). That is, the arithmetic unit 4 searches the operation history data b1 based on the extraction conditions (number of failures) input by the operator to the operation unit 3, and extracts concrete slabs (floor members) that satisfy the extraction conditions in the failure history, that is, failure-related slabs. Such step S2 corresponds to the member extraction process in the present invention.

[0035] FIG. 4 shows, for example, the result of setting the number of failures to be equal to or greater than a predetermined threshold value (for example, 2 or more) and extracting the failure-related slabs, that is, the position numbers in FIG. 2. As shown in FIG. 4, the extraction result of the failure-related slabs in step S2 satisfies the extraction conditions (number of failures) and shows the position numbers of the failure-related slabs in descending order of the number of failures.

[0036] In addition, in the extraction process of the failure-related slab in step S2, the operation period of the automated guided vehicle (AGV) can be set as the extraction condition instead of the number of failures. That is, the operator designates the operation period of the automated guided vehicle (AGV) as the second extraction condition instead of the number of failures which is the first extraction condition.

[0037] FIG. 5 shows the extraction result of the failure-related slab when the operation period of the automated guided vehicle (AGV) is set as the second extraction condition. That is, this extraction result shows the number of failures of the automated guided vehicle (AGV) in the failure-related slabs indicated by the position numbers for the first week, second week, third week, and fourth week within a month for each of the four operation periods.

[0038] Subsequently, the arithmetic unit 4 performs an extraction process of the failure content for the extraction result of step S2 (step S3). That is, when the operator operates the operation unit 2 to instruct the extraction of the failure content for the extraction result of step S2, the arithmetic unit 4 extracts the failure content for the extraction result of step S2 from the failure history of the operation history data b1. Such step S3 corresponds to the failure content acquisition step in the present invention.

[0039] FIG. 6 is an example of the processing result of step S3. This processing result shows the failure content of the automated guided vehicle (AGV) for the failure-related slabs (position numbers) where the number of failures of the automated guided vehicle (AGV) is two or more. Also, this processing result shows the AGV identification number of the automated guided vehicle (AGV) as information attached to the failure content of the automated guided vehicle (AGV).

[0040] Subsequently, the arithmetic unit 4 sets the repair target slab (repair target floor member) based on the extraction result (failure content) of step S3 (step S4). That is, the arithmetic unit 4 evaluates the relationship between the extraction result (failure content) of step S3 and the failure-related slab (position number), that is, whether each failure content is caused by a defect in the failure-related slab.

[0041] Then, the arithmetic unit 4 sets the slab to be repaired (the floor member to be repaired) based on this evaluation result. In the evaluation process in step S4, the arithmetic unit 4 refers to, for example, an evaluation table in which the relationship between the failure content and the cause of failure is registered. FIG. 7 schematically shows an example of the data structure of the evaluation table.

[0042] That is, by referring to such an evaluation table, the arithmetic unit 4 evaluates whether the failure content, which is the extraction result in step S3, exists in the failure-related slab (failure-related floor member). Instead of referring to the evaluation table, an operator may manually evaluate the relevance between the failure content and the failure-related slab and input the evaluation result into the operation unit 3.

[0043] When the arithmetic unit 4 sets the slab to be repaired in this way, it outputs the slab to be repaired to the display unit 5 and the communication unit 1 (step S5). That is, the arithmetic unit 4 causes the display unit 5 to output the slab to be repaired and display it on the screen. In addition, the arithmetic unit 4 causes the communication unit 1 to output a notification request for the slab to be repaired, thereby transmitting (notifying) the slab to be repaired to the repair work terminal C.

[0044] As described above, the repair location extraction device A according to the present embodiment is based on the operation history data b1 in which the failure position and the failure content of the automatic transport vehicle (transport machine) traveling on the transport path composed of a plurality of concrete slabs (floor members) are registered, and the arithmetic unit 4 (member extraction unit) that extracts the failure-related slab (failure-related floor member) in which the number of failures of the automatic transport vehicle is equal to or more than a predetermined threshold value (two times), the arithmetic unit 4 (failure content acquisition unit) that extracts the failure content in the failure-related slab, and the arithmetic unit 4 (repair location setting unit) that sets the slab to be repaired by evaluating whether the cause of failure of the automatic transport vehicle exists in the failure-related slab based on the failure content of the failure-related slab, and the communication unit 1 and the display unit 5 (notification unit) that notify the floor member to be repaired.

[0045] In addition, the repair location extraction method according to the present embodiment includes a member extraction step of extracting a failure-related slab (failure-related floor member) in which the number of failures of an automatic transport vehicle (transport machine) traveling on a transport path composed of a plurality of concrete slabs (floor members) is equal to or greater than a predetermined threshold value (two times) based on operation history data b1 in which the failure position and failure content of the automatic transport vehicle are registered, a failure content acquisition step of extracting the failure content in the failure-related slab, a repair location setting step of setting a repair target slab by evaluating whether the cause of the failure of the automatic transport vehicle is in the failure-related slab based on the failure content of the failure-related slab, and a notification step of notifying the repair target floor member.

[0046] According to such a present embodiment, it is possible to provide a repair location extraction device A and a repair location extraction method capable of efficiently extracting a repair target slab, which is a damaged location, for a transport path of a logistics facility composed of a plurality of concrete slabs (floor members).

[0047] Note that the present invention is not limited to the above-described embodiment, and for example, the following modification examples can be considered. (1) In the above-described embodiment, the floor member is a concrete slab constituting the transport path of the logistics facility, but the present invention is not limited thereto. That is, the present invention is applicable to various floor members other than concrete slabs.

The block diagram of FIG. 1 is an example of the functional configuration of the repair location extraction device A, and some functional components may be deleted as necessary.

[0049] (3) In the above-described embodiment, the notification unit is the communication unit 1 and the display unit 5, but the present invention is not limited thereto. A notification unit other than the communication unit 1 and the display unit 5 may be adopted.
