Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, in the technique described in Patent Document 1, there is an operation in which workers input articles into an article transport device at the input port group. Therefore, the workers need to smoothly input the articles into the article transport device so that the work does not get stuck. However, even if the quantity of articles to be transported is controlled, since the work speed varies depending on the workers, in the case of workers with a slow work speed, the transport vehicle may start moving without loading the articles, or conversely, in the case of workers with a fast work speed, there may be a risk of transport errors or a decrease in work efficiency, such as a waiting time for work until the transport vehicle starts moving and the next transport vehicle arrives. Therefore, there is a need for a technique to prevent transport errors and a decrease in work efficiency and perform accurate and efficient sorting work. However, as described above, in the technique described in Patent Document 1, it is difficult to prevent transport errors and a decrease in work efficiency and perform accurate and efficient sorting work. Therefore, the inventors focused on a mechanism that sets a stopping time for the transport vehicle during sorting operations and keeps the transport vehicle stopped until this stopping time has elapsed.
[0005] The present invention aims to provide a transport control system, transport control method, and program that prevent transport errors and decreases in work efficiency, and enable accurate and efficient sorting work. [Means for solving the problem]
[0006] This invention allows the worker The transport vehicle loads the cargo and transports it from the induction position, which is the starting position, to one of the multiple chutes, which is the destination position. A transport control system for controlling transport vehicles, wherein the transport vehicle The stopping time for the induction is determined based on the operator's past work performance. The setting unit to be set, and the operator The system starts loading the cargo into the induction mechanism and measures the stop time. The system stops the transport vehicle at the induction mechanism until the set stop time has elapsed. After the stop time has elapsed, the system releases the stop state of the transport vehicle. A transport control system is provided that includes a stopping unit.
[0007] According to the present invention, the transport vehicle stops at the starting position after the worker begins work until a set stopping time has elapsed. This makes it possible to prevent transport errors and a decrease in work efficiency by setting an appropriate stopping time, for example, and to perform accurate and efficient sorting work. Furthermore, by setting a stopping time that matches the characteristics of the worker (e.g., work speed) or the characteristics of the cargo (e.g., category (e.g., textiles, clothing, small items, fragile items, food and beverages)), it is also possible to prevent transport errors and a decrease in work efficiency and to perform accurate and efficient sorting work.
[0008] Although this invention falls under the category of a system, similar effects and benefits can be achieved with methods and programs. [Effects of the Invention]
[0009] According to the present invention, it is possible to prevent transport errors and decreases in work efficiency, and to perform accurate and efficient sorting work. [Brief explanation of the drawing]

[Figure 8] This diagram shows a flowchart of the transport instruction processing performed by computer 10. [Modes for carrying out the invention]
[0011] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the attached drawings. In the following drawings, the same elements are denoted by the same numbers or reference numerals throughout the description of the embodiments. This specification assumes that the transport control system 1 is a system that transports goods in a warehouse or the like using transport vehicles.
[0012] [Overview of Transport Control System 1] Figure 1 is a schematic diagram illustrating the overview of the transport control system 1. Based on Figure 1, the components of the transport control system 1 will be described. The transport control system 1 is a system consisting of at least a WCS (Warehouse Control System) 2 and sorting equipment 3. WCS2 is a system for controlling material handling equipment and IoT devices in a warehouse. The material handling equipment includes, for example, loading equipment such as forklifts, bunning / debunning systems, conveying equipment such as automatic guided vehicles (AGVs), overhead traveling vehicles, AI (Artificial Intelligence)-equipped automatic transfer robots, sorting equipment such as conveyors and sorters, storage equipment such as automated warehouses, shipping equipment such as digital picking systems and automatic case-making machines. In this specification, the conveying equipment and the sorting equipment are collectively referred to as sorting facilities. WCS2 includes a computer 10 having server functions, and this computer 10 may be implemented by, for example, one computer, or may be implemented by a plurality of computers like a cloud computer. This computer 10 executes each process that WCS2 executes. The cloud computer in this specification may be either one that uses any computer scalable when performing a specific function, or one that includes a plurality of functional modules to realize a certain system and freely combines and uses its functions. The sorting facility 3 consists of a transport vehicle 4 and a transport route 5. The transport vehicle 4 transports the goods loaded by the operator from the starting position (e.g., induction) to the destination position (e.g., each chute assigned as the transport destination). The transport vehicle 4 is, for example, a vehicle-type transporter (e.g., AGV) that travels on the transport route 5 described later. The transport vehicle 4 transports the goods loaded by the operator at the starting position to the destination position of the transport route 5. The transport route 5 is a route for transporting goods in the warehouse. The transport route 5 has a plurality of branch lines on which the transport vehicle 4 travels, and each of the plurality of branch lines has a destination position. This destination position corresponds to the exit of the sorting device for distributing the goods. In the figure, this destination position is indicated by a white circle. Further, the transport route 5 has a starting position of the transport vehicle 4 where the operator loads the goods onto the transport vehicle 4.
[0013] The outline of the processing steps when the conveyance control system 1 controls the conveyance vehicle 4 that conveys the luggage loaded by the operator from the departure position to the destination position will be described.
[0014] The computer 10 sets the stop time for stopping the conveyance vehicle 4 at the departure position (step S1). The departure position is, for example, a place (e.g., induction) where the operator loads the luggage onto the conveyance vehicle 4. The stop time is the time required for the operator to load the luggage onto the conveyance vehicle 4. The computer 10 sets this stop time for each operator based on predetermined conditions. The predetermined conditions are, for example, a predetermined time, the actual performance value of the work for each operator (e.g., the time required for the work of each past operator), and the work efficiency of the work for each operator (e.g., calculated from the time required for the work and the work speed).
[0015] The computer 10 stops the conveyance vehicle 4 at the departure position until the set stop time elapses after the start of the operator's work (step S2). The computer 10 starts counting the set stop time according to the identifier of the operator and the image taken of the working state, etc. That is, the computer 10 starts counting the stop time after the start of the operator's work. The operator loads the luggage onto the conveyance vehicle 4 during this stop time. When the computer 10 determines that the set stop time has elapsed, it instructs the conveyance vehicle 4 to convey the loaded luggage. That is, the computer 10 stops the conveyance vehicle 4 at the departure position until the set stop time elapses after the start of the operator's work. After the completion of this stop time, the computer 10 instructs the conveyance vehicle 4 to convey the loaded luggage.
[0016] The above is the outline of the conveyance control system 1. According to this conveyance control system 1, it is possible to prevent conveyance errors and a decrease in work efficiency, and to perform accurate and efficient sorting work.
[0017] [Device Configuration] Figure 2 is a block diagram showing the configuration of the transport control system 1. The transport control system 1 is a system that controls the transport vehicle 4 that transports the cargo loaded by the worker from the starting position to the destination position, and consists of at least a WCS 2 and sorting equipment 3 (transport vehicle 4 and transport route 5). The transport control system 1 is configured such that the WCS 2 and sorting equipment 3 are each connected to a network 7 such as a public telephone network or an intranet, enabling data communication. It should be noted that the components of the transport control system 1 are merely an example, and the number, type, and function of terminals, devices, etc. not shown in the diagram can be changed as appropriate.
[0018] As described above, WCS2 is a system for controlling material handling equipment and IoT devices in a warehouse. As described above, WCS2 is a system in which a computer 10 with server functionality is included and performs various processes. The computer 10 includes a control unit consisting of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc., and a communication unit consisting of a device for enabling communication with other terminals and devices, and a stop unit 11 that stops the transport vehicle 4 at the starting position after the worker starts work until a set stop time has elapsed. Computer 10 includes a recording unit, which includes a data storage unit using a hard disk, semiconductor memory, recording media, memory card, etc. The computer 10 includes, as a processing unit, various devices for executing various processes, a setting unit 12 for setting the stopping time for stopping the transport vehicle 4 at the starting position, and the like.
[0019] In computer 10, the control unit loads a predetermined program and, in cooperation with the communication unit, realizes a transport instruction module, a stop module, a work content information acquisition module, and a cargo information acquisition module. Furthermore, in the computer 10, the control unit loads a predetermined program and, in cooperation with the recording unit, realizes a setting result recording module, a specific result recording module, and a change result recording module. Furthermore, in the computer 10, the control unit loads a predetermined program and, in cooperation with the processing unit, realizes a setting module, a work content identification module, a stop time identification module, a change module, a timing module, and a decision module.
[0020] As described above, the transport vehicle 4 transports the loads loaded by the worker from the starting position (e.g., induction) to the destination position (e.g., each chute to which a destination is assigned). The transport vehicle 4 is, for example, a transport device such as a vehicle-type transporter (e.g., an AGV) that travels along the transport route 5. In this embodiment, the transport vehicle 4 will be described as a vehicle-type transporter. Based on instructions from WCS2, the transport vehicle 4 performs actions such as stopping at the starting position and traveling along the transport path 5. The transport vehicle 4 travels to the starting position, where the worker loads the cargo. The transport vehicle 4 stops at the starting position based on the stopping time set by WCS2. After this stopping time has elapsed, the transport vehicle 4 travels to a predetermined destination position with the cargo loaded, and drops the cargo at this destination position. After dropping the cargo, the transport vehicle 4 travels to a predetermined position (for example, the starting position). It should be noted that the transport vehicle 4 is merely an example, and the transport unit in this invention is not limited to the transport vehicle 4.
[0021] As described above, the transport route 5 is a route for transporting goods in a warehouse, and has multiple branch lines on which the transport vehicle 4 travels, with each of the branch lines having a target position. The transport route 5 also has a starting position for the transport vehicle 4 from which workers load goods. The transport route 5 is, for example, a sorting device such as a conveyor. In this embodiment, the transport route 5 will be described as a conveyor. The transport route 5 consists of one main line and several branch lines connected to this main line (see Figure 3). Each of these branch lines has one or more destination locations. As described above, these destination locations correspond to the exits of sorting devices for distributing goods. The transport route 5 also has a starting position for the transport vehicle 4 on the main line.
[0022] The sorting equipment 3 will be explained based on Figure 3. This figure schematically shows an example of sorting equipment 3. In this figure, the sorting equipment 3 consists of a transport vehicle 4 and a transport route 5. The transport route 5 consists of a main line 20 and a first branch line 21, a second branch line 22, and a third branch line 23 connected to the main line 20. The main line 20 has an induction point 25 set up, which is the starting position for the transport vehicle 4. The induction point 25 is where the workers perform their tasks and where the goods are loaded onto the transport vehicle 4. The first branch line 21 has a rectangular structure, with five chutes 24, which are the target positions for the transport vehicle 4, set on one long side, and five chutes 24, which are the target positions for the transport vehicle 4, set on the other long side. Similarly, the second branch line 22 and the third branch line 23 have a rectangular structure, with five chutes 24, which are the target positions for the transport vehicle 4, set on one long side, and five chutes 24, which are the target positions for the transport vehicle 4, set on the other long side. The transport vehicle 4 travels along the transport path 5 from the induction 25 towards one of the chutes 24, and transports the cargo. It should be noted that the transport route 5 described above is merely an example, and the transport route in this invention is not limited to the transport route 5 shown in Figure 3. Similarly, the position, number, and other details of the chute 24 and induction 25 etc. set in the transport route 5 are not limited to those shown in Figure 3.
[0023] The following describes each process performed by the transport control system 1, along with the processes performed by each module described above. In this specification, each module may perform its processing as a function of its own making, or it may perform it through a predetermined application.
[0024] [Configuration process performed by computer 10] Based on Figure 4, the setting process performed by the computer 10 will be explained. This figure is a flowchart of the setting process performed by the computer 10. This setting process is a detailed explanation of the setting process (step S1) that sets the stopping time for stopping the transport vehicle 4 at the starting position.
[0025] The setting module sets the stopping time for the transport vehicle 4 to stop at the starting position (step S10). As described above, the starting position is the induction 25 where the worker loads the cargo onto the transport vehicle 4 (hereinafter also simply referred to as "the work"). The stopping time is the time required for the worker to perform the work. The configuration module sets this downtime for each worker. The configuration module sets this downtime based on one or a combination of the following: a predetermined time, the actual time taken for each worker's work, and the work efficiency of each worker. The actual time taken is the time taken for each worker to complete the work in the previous or earlier period. Work efficiency is calculated from the time taken for the worker to complete the work and their work speed. If the configuration module sets the downtime based on a predetermined time, this time will be set as the downtime for each worker. When the setting module sets the downtime based on the actual values for each worker, it sets the downtime for each worker to the actual value itself, the time obtained by increasing or decreasing this actual value by a predetermined amount, the average time of this actual value, the longest time of this actual value, the shortest time of this actual value, etc. Alternatively, the setting module may perform machine learning or similar methods using the actual values as training data to learn about downtime for each worker, and set the downtime based on the results of this learning. When the configuration module sets downtime based on the work efficiency of each worker, it calculates the time that is optimal for each worker's work efficiency and sets this calculated time as the downtime for each worker.
[0026] 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, associating it with the worker's identifier.
[0027] The above completes the setup process. The transport control system 1 uses the stop time set by the setting process described above for the process described later.
[0028] [Stopping process performed by computer 10] The stopping process performed by the computer 10 will be explained based on Figure 5. This figure is a flowchart of the stopping process performed by the computer 10. This stopping process is a detailed description of the process before the start of work in the stopping process (step S2) that stops the transport vehicle 4, as described above, at the starting position until the set stopping time has elapsed after the worker has started work. This stopping process is performed after the setting process described above.
[0029] The transport instruction module instructs the transport vehicle 4 to move to the starting position (step S20). The transport instruction module transmits a command to the transport vehicle 4 to move to the starting position. Transport vehicle 4 receives this instruction. Based on this instruction, transport vehicle 4 moves to the starting position.
[0030] The stop module instructs the transport vehicle 4 to stop at the starting position (step S21). The stop module, upon detecting that the transport vehicle 4 has arrived at the starting position, transmits an instruction to the transport vehicle 4 to stop at this starting position. Transport vehicle 4 receives this instruction. Based on this instruction, transport vehicle 4 stops at the starting position.
[0031] The above is the termination process. The transport control system 1 performs the following processing on the transport vehicle 4, which is stopped due to the stop process described above.
[0032] [Specific processes to be performed by computer 10] Based on Figure 6, the specific process performed by computer 10 will be described. This figure is a flowchart of the specific process performed by computer 10. This specific process is performed after the setup process described above.
[0033] The work content information acquisition module acquires work content information related to the worker's work (step S30). The worker's work details refer to the worker performing the work at the starting position and the work situation. The work details information is the information necessary to identify the worker performing the work at the starting position and the work situation, and includes, for example, worker information (e.g., identifier) and images of the area around the starting position. The work content information acquisition module acquires worker information of workers performing tasks at the starting position from a computer that manages shift data, etc. The module also acquires images of workers performing tasks around the starting position and images of the surrounding area taken by cameras or other imaging devices installed near the starting position. The computer and imaging equipment transmit the above-mentioned information and images to the computer 10 as work content information. The work content information acquisition module acquires work content information related to the worker's work by receiving these.
[0034] 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 to identify the work currently being performed at the starting position. The work content identification module identifies workers based on their identifiers in the work content information. It also identifies the workers and the condition of the goods depicted in the images within 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 that worker has started the work.
[0035] The downtime determination module determines the downtime based on the identified work content (step S32). The downtime identification module identifies the downtime based on the worker performing the identified task. The downtime identification module identifies the downtime associated with the worker identified in this instance through the setting process described above.
[0036] The specific result recording module records the identified stop time (step S33). The specific result recording module records the identified downtime in association with the identified work content.
[0037] The above describes the specific processing steps. The transport control system 1 uses the stop time determined by the specific processing described above to execute the processing described later.
[0038] [Changes performed by computer 10] Based on Figure 7, the change process performed by computer 10 will be described. This figure is a flowchart of the change process performed by computer 10. This change process is performed after the specific process described above.
[0039] The cargo information acquisition module acquires cargo information about the cargo to be loaded (step S40). The cargo information is information about the cargo to be loaded onto the transport vehicle 4, and includes, for example, an identifier, name, category, quantity, and destination. When loading cargo onto transport vehicle 4, the worker reads the cargo information of the cargo using a scanner. The scanner transmits the scanned cargo information to computer 10. The cargo information acquisition module obtains cargo information about the cargo to be loaded by receiving this cargo information.
[0040] The modification module changes the stop time according to the acquired cargo information (step S41). The modification module changes the stop time according to the category in the acquired cargo information. The modification module changes this stop time for each category based on the result of a prior evaluation of the ease of loading the cargo. A higher evaluation indicates that the cargo is easier to load. The modification module shortens the stop time for cargo in categories with a high evaluation (relatively easy to load) and lengthens the stop time for cargo in categories with a low evaluation (relatively difficult to load). In addition to shortening or lengthening the stop time by a predetermined amount, the modification module can also leave it unchanged. That is, the modification module selects the appropriate option from three options: adding a predetermined amount of time, subtracting a predetermined amount of time, or neither adding nor subtracting, and changes the stop time based on the result of the selection. For example, the change module shortens the stop time by 1 second if the cargo category is easy to load onto the transport vehicle 4 (e.g., small items), lengthens the stop time by 1 second if the cargo category is difficult to load onto the transport vehicle 4 (e.g., fragile items), and leaves the stop time unchanged if the cargo category is neither easy nor difficult to load onto the transport vehicle 4 (e.g., food and beverages). Furthermore, the modification module may change the stop time depending on cargo information other than the category. In this case, the modification module should change the stop time according to the ease of loading the cargo as indicated in the cargo information. Furthermore, in the process of step S41, the modification module changes the stop time using the results of a prior evaluation of the ease of loading, but the stop time may also be changed based on other methods.
[0041] The change result recording module records the changed downtime (step S42). The change result recording module records the changed downtime and associates it with the worker identifier associated with the previous downtime.
[0042] The above describes the change process. The transport control system 1 uses the stop time changed by the modification process described above to execute the process described later. Note that the above-mentioned modification process is not necessarily required. If the transport control system 1 does not perform this modification process, it may simply execute the process in the transport instruction process described later, using the stop time set by the above-mentioned setting process.
[0043] [Transport instruction processing executed by computer 10] Based on Figure 8, the transport instruction processing performed by the computer 10 will be explained. The figure is a flowchart of the transport instruction processing performed by the computer 10. This transport instruction processing is a detailed description of the stop processing (step S2) that stops the transport vehicle 4, as described above, at the starting position until a set stop time has elapsed after the worker has started working. This transport instruction processing is performed after the change processing described above.
[0044] The timing module starts timing the downtime according to the acquired work content information (step S50). The timing module starts timing downtime according to the worker's work content, which is identified based on the acquired work content information. The timing module starts timing downtime when the worker's work content is determined to be the start of the worker's work. During the stop time, the worker loads the goods onto the transport vehicle 4. The transport vehicle 4 remains stopped due to the stop procedure described above even when the timing starts again.
[0045] The decision module determines whether or not the stop time has elapsed (step S51). The stop time determined by the decision module is the one changed by the modification process described above. If the modification process is not performed, the stop time is the one set by the configuration process described above. If the decision module determines that the stop time has not elapsed (step S51 NO), the computer 10 repeats this process. At this time, the transport vehicle 4 continues to stop due to the stop process described above and remains stopped at the starting position.
[0046] On the other hand, if the decision module determines that the stop time has elapsed (step S51 YES), the transport instruction module instructs the transport vehicle 4 to transport the cargo (step S52). The transport instruction module transmits instructions for transporting the cargo to the transport vehicle 4. The transport vehicle 4 receives these instructions. Upon receiving this instruction, transport vehicle 4 releases its stopped state and travels towards the designated destination location for the cargo. After arriving at this destination location, transport vehicle 4 drops the loaded cargo. After dropping the cargo, transport vehicle 4 travels to its designated position.
[0047] The above describes the process for processing transport instructions.
[0048] Although the processes described above are listed as separate processes, computer 10 can also be configured to execute some or all of the processes described above in combination. Furthermore, computer 10 can be configured to execute each process at times other than those described.
[0049] The means and functions described above are realized by a computer (including the CPU, information processing unit, and various terminals) reading and executing a predetermined program. The program may be provided, for example, via a network from the computer (SaaS: Software as a Service) or as a cloud service. Alternatively, the program may 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. Alternatively, the program may be pre-recorded on a recording device (recording medium) and provided to the computer from that recording device via a communication line.
