Abstract

[Problem] To prevent a transport error and a decrease in work efficiency and perform accurate and efficient sorting work. [Solution] A transport control system 1 for controlling a transport vehicle 4 that transports a cargo loaded by a worker from a start position to a destination position sets a stop time in which the transport vehicle 4 is stopped at the start position and stops the transport vehicle 4 at the start position until the set stop time elapses after the worker starts work. The transport control system 1 also sets said stop time on the basis of, for example, an achievement value. The transport control system 1 also acquires work content information relating to a work content of the worker and starts clocking of the stop time according to said work content information. The transport control system 1 also acquires cargo information relating to the cargo to be loaded and changes the stop time according to said cargo information.

Description

Transport control system, transport control method, and program

The present invention relates to technology that is effective in controlling transport vehicles that transport luggage loaded by workers in warehouses, etc.

Conventionally, as a sorting system for transported goods in a warehouse, there is a control system for a transport vehicle that carries goods inserted through an goods input port to each chute. For example, Patent Document 1 discloses a sorting system that controls the number of goods transported to the goods receiving section, distributes the burden on workers fairly, and improves overall work efficiency.

JP 2013-245087 A

However, in the technology described in Patent Document 1, a worker must input articles into the article conveying device through an input port group. For this reason, the worker must smoothly input articles into the article conveying device so as not to cause a delay in the work.
However, even if the number of items being transported is controlled, the working speed of each worker differs, so if a worker works slowly, the transport vehicle may depart without loading any items. Conversely, if a worker works fast, there is a risk of a transport vehicle leaving the site and having to wait until the next transport vehicle arrives, resulting in transport errors and reduced work efficiency.
Therefore, there is a demand for technology that can prevent transport errors and reduced work efficiency and perform sorting work accurately and efficiently.
However, as described above, with the technology described in Patent Document 1, it is difficult to prevent conveyance errors and reduced work efficiency and to perform accurate and efficient sorting work.
Therefore, the present inventors have focused on a mechanism for setting a stop time for the transport vehicle during sorting work and stopping the transport vehicle until this stop time has elapsed.

The present invention aims to provide a transport control system, a transport control method, and a program that prevent transport errors and reduced work efficiency and enable accurate and efficient sorting work.

The present invention is a transport control system that controls a transport vehicle that transports luggage loaded by a worker from a starting position to a destination position,
a setting unit that sets a stop time for stopping the transport vehicle at the starting position;
a stop unit that stops the transport vehicle at the starting position until the set stop time has elapsed after the worker starts working;
The present invention provides a transport control system comprising:

According to the present invention, after the worker starts working, the transport vehicle stops at the starting position until the set stop time has elapsed. This makes it possible to prevent transport errors and reduced work efficiency by, for example, setting an appropriate stop time, and to perform accurate and efficient sorting work. Furthermore, by setting a stop time that matches, for example, the characteristics of the worker (e.g., work speed) and the characteristics of the luggage (e.g., category (e.g., textiles, clothing, small items, fragile items, food and beverages)), it is possible to prevent transport errors and reduced work efficiency, and to perform accurate and efficient sorting work.

This invention is in the category of a system, but the same effects and advantages can be achieved with methods and programs.

The present invention makes it possible to prevent transport errors and reduced work efficiency, and to perform sorting work accurately and efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of the present invention will be given with reference to the accompanying drawings. In the following drawings, the same elements are designated by the same numbers or symbols throughout the description of the embodiments.
In this specification, it is assumed that the transport control system 1 is a system for transporting luggage in a warehouse or the like using a transport vehicle.

[Overview of transport control system 1]
FIG. 1 is a schematic diagram for explaining an overview of a transport control system 1. As shown in FIG.
The components of the transport control system 1 will be described with reference to FIG.
The transport control system 1 is a system that includes at least a WCS (warehouse control system) 2 and a sorting facility 3 .
WCS2 is a system for controlling material handling equipment and IoT devices in a warehouse. Material handling equipment includes, for example, loading equipment such as forklifts and vanning/devanning systems, transport equipment such as automatic guided vehicles (AGVs), overhead traveling vehicles, and artificial intelligence (AI)-equipped automatic transport robots, sorting equipment such as conveyors and sorters, storage equipment such as automated warehouses, digital picking systems, and shipping equipment such as automatic box-making machines. In this specification, transport equipment and sorting equipment are collectively referred to as sorting equipment.
The WCS 2 includes a computer 10 having a server function, and this computer 10 may be realized, for example, as a single computer, or may be realized as a plurality of computers such as a cloud computer. This computer 10 executes each process executed by the WCS 2.
In this specification, a cloud computer may refer to either a scalable use of any computer to perform a specific function, or a computer that includes multiple functional modules to realize a system, the functions of which can be freely combined.
The sorting equipment 3 comprises a transport vehicle 4 and a transport path 5 .
The transport vehicle 4 transports the baggage loaded by the worker from a starting position (e.g., induction) to a destination position (e.g., each chute to which a destination is assigned). The transport vehicle 4 is, for example, a vehicle-type transport machine (e.g., AGV) that travels on a transport path 5 described later. The transport vehicle 4 transports the baggage loaded by the worker at the starting position to a destination position on the transport path 5.
The conveying route 5 is a route for conveying luggage in a warehouse. The conveying route 5 has a number of branch lines along which the conveying vehicles 4 run, and each of the branch lines has a destination position. This destination position corresponds to the exit of a sorting device for distributing products. In the figure, this destination position is indicated by a white circle. The conveying route 5 also has a departure position of the conveying vehicles 4 where workers load luggage onto the conveying vehicles 4.

This section describes an overview of the processing steps that the transport control system 1 performs when controlling a transport vehicle 4 that transports luggage loaded by a worker from a starting position to a destination position.

The computer 10 sets a stopping time for stopping the transportation vehicle 4 at the starting position (step S1).
The starting position is, for example, a location (e.g., induction) where a worker loads luggage onto the transport vehicle 4. The stopping time is a time required for a worker to load luggage onto the transport vehicle 4.
The computer 10 sets this stop time for each worker based on a predetermined condition, such as a predetermined time, a performance value of each worker's work (e.g., the time required for each worker to perform a task in the past), or a work efficiency of each worker's work (e.g., calculated from the time required for a task and the work speed).

The computer 10 stops the transport vehicle 4 at the starting position after the worker starts work until a set stop time has elapsed (step S2).
The computer 10 starts timing the set stop time according to the identifier of the worker, the image captured during the work, etc. That is, the computer 10 starts timing the stop time after the worker starts the work. The worker loads the baggage onto the transport vehicle 4 during this stop time.
When the computer 10 determines that the set stop time has elapsed, it instructs the transport vehicle 4 to transport the loaded baggage. That is, the computer 10 stops the transport vehicle 4 at the starting position after the worker starts work until the set stop time has elapsed. After the stop time is completed, the computer 10 instructs the transport vehicle 4 to transport the loaded baggage.

The above is an overview of the transport control system 1.
According to the present transport control system 1, transport errors and reduced work efficiency can be prevented, and sorting work can be performed accurately and efficiently.

[Device configuration]
2 is a block diagram showing the configuration of the transport control system 1. The transport control system 1 is a system that controls transport vehicles 4 that transport luggage loaded by workers from a starting position to a destination position, and is composed of at least a WCS 2 and a sorting facility 3 (the transport vehicles 4 and the transport route 5).
In the transport control system 1, the WCS 2 and the sorting equipment 3 are each connected to each other so as to be able to communicate data with each other via a network 7 such as a public line network or an intranet.
The components of the transport control system 1 are merely examples, and the number, types, and functions of terminals and devices not shown in the figures can be changed as appropriate.

As described above, the WCS 2 is a system for controlling material handling equipment and IoT devices in a warehouse. As described above, in the WCS 2, the computer 10 having a server function included in the system executes various processes.
The computer 10 includes, as a control unit, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., and, as a communication unit, includes a device for enabling communication with other terminals, devices, etc., and a stopping unit 11 that stops the transport vehicle 4 at the starting position after the worker starts work until a set stopping time has elapsed.
The computer 10 includes a recording unit, such as a hard disk, a semiconductor memory, a recording medium, a data storage unit such as a memory card, and the like.
The computer 10 includes, as processing units, various devices for executing various processes, a setting unit 12 for setting a stop time for stopping the transport vehicle 4 at the starting position, and the like.

In the computer 10, the control unit loads a predetermined program and cooperates with the communication unit to realize a transport instruction module, a stop module, a work content information acquisition module, and a package information acquisition module.
In addition, in the computer 10, the control unit reads a predetermined program, and thereby cooperates with the recording unit to realize a setting result recording module, a specific result recording module, and a change result recording module.
In addition, in the computer 10, the control unit reads a predetermined program and cooperates with the processing unit to realize a setting module, a work content identification module, a stop time identification module, a change module, a timing module, and a judgment module.

As described above, the transport vehicle 4 transports the baggage loaded by the worker from a starting position (e.g., induction) to a destination position (e.g., each chute to which a destination is assigned). The transport vehicle 4 is, for example, a transport facility such as a vehicle-type transport machine (e.g., AGV) that travels on the transport path 5. In this embodiment, the transport vehicle 4 will be described as a vehicle-type transport machine.
The transport vehicle 4 stops at the starting position, travels on the transport route 5, etc., based on instructions from the WCS 2, etc. The transport vehicle 4 travels to the starting position, and a worker loads the baggage onto the transport vehicle 4. The transport vehicle 4 stops at the starting position based on the stop time set by the WCS 2. After this stop time has elapsed, the transport vehicle 4 travels to a predetermined destination position with the baggage loaded, and drops the loaded baggage onto the destination position. After dropping the baggage, the transport vehicle 4 travels to a predetermined position (e.g., the starting position).
It should be noted that the transport vehicle 4 is merely an example, and the transport unit in the present invention is not limited to the transport vehicle 4 .

As described above, the conveying route 5 is a route for conveying luggage in a warehouse, and has a plurality of branch lines along which the conveying vehicles 4 run, each of which has a destination position. The conveying route 5 also has a starting position of the conveying vehicles 4 where workers load luggage onto the conveying vehicles 4. The conveying route 5 is, for example, a sorting device such as a conveyor. In this embodiment, the conveying route 5 will be described as a conveyor.
The conveying route 5 is composed of one trunk line and multiple branch lines connected to the trunk line (see FIG. 3). The conveying route 5 has one or multiple destination positions on each of the multiple branch lines. As described above, these destination positions correspond to the exit of a sorting device for distributing products. The conveying route 5 also has a starting position for the conveying vehicle 4 on one trunk line.

The sorting equipment 3 will be described with reference to Fig. 3. This figure is a schematic diagram of an example of the sorting equipment 3. In this figure, a transport vehicle 4 and a transport path 5 are shown as the sorting equipment 3.
The conveying route 5 is composed of a trunk line 20 and a first branch line 21 , a second branch line 22 and a third branch line 23 connected to the trunk line 20 .
An induction 25, which is a starting position of the transport vehicle 4, is set on the main line 20. The induction 25 is a place where workers perform work and where the transport vehicle 4 is loaded with luggage.
The first branch 21 has a rectangular structure, and five chutes 24, which are the destination positions of the transport vehicle 4, are set on one side of the long side, and five chutes 24, which are the destination positions of the transport vehicle 4, are set on the other side of the long side.
The second branch 22 and the third branch 23 also have a rectangular structure, with five chutes 24, which are the destination positions of the transport vehicle 4, set on one side of the long side, and five chutes 24, which are the destination positions of the transport vehicle 4, set on the other side of the long side.
The transport vehicle 4 travels along the transport path 5 from this induction 25 toward one of the chutes 24 to transport the luggage.
The above-mentioned conveying path 5 is merely an example, and the conveying path in the present invention is not limited to the conveying path 5 shown in Fig. 3. Similarly, the chutes 24 and inductions 25 set on the conveying path 5, as well as their positions, numbers, and other details, are not limited to those shown in Fig. 3.

Hereinafter, each process executed by the transport control system 1 will be described together with the processes executed by each of the modules described above.
In this specification, each module may execute its processing contents as its own function, or may execute its processing contents via a predetermined application.

[Setting process executed by computer 10]
The setting process executed by the computer 10 will be described with reference to Fig. 4. Fig. 4 is a flowchart showing the setting process executed by the computer 10. This setting process is a detailed description of the setting process (step S1) for setting the stop time for stopping the transport vehicle 4 at the starting position.

The setting module sets a stop time for stopping the transportation vehicle 4 at the starting position (step S10).
As described above, the starting position is the induction 25 where the worker loads the baggage onto the transport vehicle 4 (hereinafter, also simply referred to as the work). The stop time is the time required for the worker to perform the work.
The setting module sets this stop time for each worker. The setting module sets this stop time based on any one or a combination of a predetermined time, a performance value of the work for each worker, and the work efficiency of the work for each worker. The performance value is the time required for the work for each worker in the previous or any time before that. The work efficiency is calculated from the time required for the work by the worker and the work speed.
When the setting module sets the downtime based on a predetermined time, this time is set as the downtime for each worker.
When the setting module sets the stop time based on the performance value for each worker, the stop time for each worker is set to the time of the performance value itself for each worker, the time obtained by increasing or decreasing this performance value by a predetermined amount, the time of the average value of this performance value, the longest time of this performance value, the shortest time of this performance value, etc. The setting module may learn about the stop time for work by machine learning or the like using the performance value as training data for each worker, and set the stop time based on the results of this learning.
When the setting module sets the stop time based on the work efficiency of each worker, the setting module calculates the time at which the work efficiency of each worker is optimal, and sets this calculated time as the stop time for each worker.

The setting result recording module records the set stop time (step S11).
The setting result recording module records the stop time set for each worker in association with the identifier of the worker.

This completes the setting process.
The transport control system 1 uses the stop time set by the above-mentioned setting process in the process described below.

[Stopping process executed by computer 10]
The stop processing executed by the computer 10 will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the stop processing executed by the computer 10. This stop processing is a detailed description of the stop processing (step S2) performed before the start of work, in which the above-mentioned transport vehicle 4 is stopped at the starting position after the worker starts work until a set stop time has elapsed. This stop processing is a processing performed after the above-mentioned setting processing.

The transport instruction module instructs the transport vehicle 4 to travel to the starting position (step S20).
The transportation instruction module transmits an instruction to the transportation vehicle 4 to travel to the starting position.
The guided vehicle 4 receives this instruction. Based on this instruction, the guided vehicle 4 travels to the starting position.

The stop module instructs the transport vehicle 4 to stop at the starting position (step S21).
When the transport vehicle 4 arrives at the starting position, the stopping module transmits an instruction to the transport vehicle 4 to stop at the starting position.
The transportation vehicle 4 receives this instruction. Based on this instruction, the transportation vehicle 4 stops at the starting position.

This is the stop process.
The transport control system 1 performs the process described below on the transport vehicle 4 that is stopped by the above-mentioned stop process.

[Specific Processing Executed by Computer 10]
The specific processing executed by the computer 10 will be described with reference to Fig. 6. Fig. 6 is a flowchart showing the specific processing executed by the computer 10. This specific processing is processing carried out after the setting processing described above.

The work content information acquisition module acquires work content information relating to the work content of the worker (step S30).
The work content of the worker is the worker performing the work at the starting position and the work situation. The work content information is information necessary to identify the worker performing the work at the starting position and the work situation, for example, worker information about the worker (e.g., an identifier) and an image of the vicinity of the starting position.
The work content information acquisition module acquires worker information of workers working at the starting position from a computer or the like that manages shift data, etc. The work content information acquisition module also acquires images of workers working around the starting position and images of the situation around the starting position captured by an imaging device such as a camera installed near the starting position.
The computer, the imaging device, etc. transmit the above-mentioned information and images to the computer 10 as work content information.
The work content information acquisition module receives these to acquire work content information relating to the work content of the worker.

The work content identification module identifies the work content based on the acquired work content information (step S31).
The work content identification module analyzes the acquired work content information and identifies the work content currently being performed at the starting position.
The work content identification module identifies a worker based on an identifier of the worker in the work content information. Also, the work content identification module identifies the worker and the status of the package shown in an image based on an image in the work content information.
As a result, the work content identification module identifies the identifier of the worker performing the work and whether or not this worker has started the work.

The downtime identification module identifies the downtime based on the identified work content (step S32).
The downtime identification module identifies a downtime based on the worker in the identified work content. The downtime identification module identifies a downtime associated with the currently identified worker through the above-mentioned setting process.

The identification result recording module records the identified stop time (step S33).
The identification result recording module records the identified stop time and the currently identified work content in association with each other.

The above is the specific process.
The transport control system 1 executes the process described below using the stop time identified by the above-mentioned identification process.

[Change Processing Executed by Computer 10]
The change processing executed by the computer 10 will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the change processing executed by the computer 10. This change processing is processing carried out after the above-mentioned specification processing.

The baggage information acquisition module acquires baggage information related to the baggage to be loaded (step S40).
The cargo information is information about the cargo to be loaded onto the transport vehicle 4, such as the identifier, name, category, quantity, and shipping destination.
When loading an item onto the transport vehicle 4, the worker reads the item information of the item using a scanner. The scanner transmits the read item information of the item to the computer 10.
The baggage information acquisition module receives this baggage information and thereby acquires baggage information relating to the baggage to be loaded.

The change module changes the stop time in accordance with the acquired cargo information (step S41).
The change module changes the stop time according to the category in the acquired baggage information. The change module changes this stop time based on the result of a pre-evaluation of the ease of loading baggage for each category. The higher the evaluation, the easier it is to load baggage. The change module shortens the stop time of baggage in a category with a high evaluation (relatively easy to load), and lengthens the stop time of baggage in a category with a low evaluation (relatively difficult to load). Note that the change module is not only capable of shortening or lengthening the stop time by a predetermined time, but is also capable of not changing it at all. In other words, the change module selects an appropriate option from among three options: adding or subtracting a predetermined time from the stop time, or not adding or subtracting, and changes the stop time based on the selected result.
For example, the change module shortens the stop time by one second if the category is easy to load onto the transport vehicle 4 (e.g., small items), lengthens the stop time by one second if the category is difficult to load onto the transport vehicle 4 (e.g., fragile items), and leaves the stop time unchanged if the category is neither easy nor difficult to load onto the transport vehicle 4 (e.g., food and beverages).
The change module may change the stop time in accordance with baggage information other than the category. In this case, the change module may change the stop time in accordance with the ease of loading the baggage in the baggage information.
Furthermore, in the process of step S41, the change module changes the stop time using the result of a pre-evaluation of the ease of loading, but the stop time may be changed based on another method.

The change result recording module records the changed stop time (step S42).
The change result recording module records the changed downtime in association with the identifier of the worker associated with the downtime before the change.

This completes the change process.
The transport control system 1 executes the process described below using the stop time changed by the above-mentioned change process.
It is not necessary to execute the above-mentioned change process. If the transport control system 1 does not execute this change process, the transport instruction process described later may be executed using the stop time set by the above-mentioned setting process.

[Transport instruction process executed by computer 10]
The transport instruction process executed by the computer 10 will be described with reference to Fig. 8. This figure shows a flowchart of the transport instruction process executed by the computer 10. This transport instruction process is a detailed process performed after the start of the stop process (step S2) in which the transport vehicle 4 is stopped at the starting position after the worker starts work until a set stop time has elapsed. This transport instruction process is a process performed after the change process described above.

The timing module starts timing the stop time in accordance with the acquired work content information (step S50).
The timing module starts timing the stop time according to the work content of the worker identified based on the acquired work content information. The timing module starts timing the stop time when the work content of the worker indicates that the worker has started working.
During the stopped time, the worker loads the baggage onto the transport vehicle 4. Even when the timing is started, the transport vehicle 4 continues to be stopped due to the above-mentioned stopping process.

The determination module determines whether or not the stop time has elapsed (step S51).
The stop time determined by the determination module is the time changed by the above-mentioned change process. If the change process is not performed, the stop time is the time set by the above-mentioned setting process.
When the determination module determines that the stop time has not elapsed (step S51: NO), the computer 10 repeats this process. At this time, the transportation vehicle 4 continues to be stopped by the above-mentioned stop process and remains stopped at the starting position.

On the other hand, if the determination module determines that the stop time has elapsed (YES in step S51), the transport instruction module instructs the transport vehicle 4 to transport the package (step S52).
The transport instruction module transmits an instruction for transporting the package to the transport vehicle 4. The transport vehicle 4 receives this instruction.
Upon receiving this instruction, the transport vehicle 4 releases its stopped state and travels toward the destination location to which the cargo is assigned. After arriving at the destination location, the transport vehicle 4 drops the cargo it has loaded. After dropping the cargo, the transport vehicle 4 travels to the specified location.

The above is the transport instruction process.

Although each of the above processes is described as a separate process, the computer 10 can be configured to execute a combination of some or all of the above processes. Also, the computer 10 can be configured to execute each process at a timing other than that described.

The program may be provided, for example, from the computer via a network (Software as a Service: SaaS) or as a cloud service. The program may also be provided in a form recorded on a computer-readable recording medium. In this case, the computer reads the program from the recording medium, transfers it to an internal or external recording device, records it, and executes it.
