Description

Technical Field

[0001] The present invention relates to a technology for efficiently controlling a transport vehicle that transports goods loaded by an operator in a transport warehouse or the like. Background Art

[0002] Conventionally, as a sorting device for articles to be transported in a warehouse, there has been a control system for a transport vehicle that transports articles input from an article input port to respective chutes. For example, Patent Document 1 discloses a sorting device that improves the overall operation efficiency by fairly distributing the burden on operators by controlling the number of articles to be transported to an article loading section. Prior Art Documents Patent Documents

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2013-245087 Summary of the Invention Technical Problem to be Solved by the Invention

[0004] However, in the technology described in Patent Document 1, there is an operation in which an operator places an article in an article transport device at an input port group. Therefore, in order to avoid operation backlog, the operator needs to smoothly place the article in the article transport device. However, even if the number of articles to be transported is controlled, since the operation speed varies depending on the operator, there is a risk of transport errors and a decrease in operation efficiency. For example, when the operation speed of the operator is slow, the transport vehicle departs without loading the article, and in contrast, when the operation speed of the operator is fast, the transport vehicle has departed but the next transport vehicle has not arrived yet, resulting in an operation waiting time. Therefore, a technology is needed that can prevent transport errors and a decrease in operation efficiency and perform sorting work accurately and efficiently. However, as described above, in the technology described in Patent Document 1, it is difficult to prevent transport errors and a decrease in operation efficiency, and it is difficult to perform sorting work accurately and efficiently. Therefore, the present inventors focused on a mechanism for setting a stop time for a transport vehicle during sorting operations and stopping the transport vehicle until the stop time has elapsed.

[0005] An object of the present invention is to provide a transport control system, a transport control method, and a program that can prevent transport errors and a decrease in operation efficiency and perform sorting work accurately and efficiently. Technical Means for Solving the Problem

[0006] The present invention provides a transport control system for controlling a transport vehicle to transport goods loaded by an operator from a departure position to a target position, the transport control system comprising: A setting unit that sets a stop time for stopping the transport vehicle at the departure position; and A stop unit that stops the transport vehicle at the departure position until the set stop time elapses after the operator starts working.

[0007] According to the present invention, the transport vehicle stops at the departure position until the set stop time elapses after the operator starts working. Thus, for example, by setting an appropriate stop time, it is possible to prevent transportation errors and a decrease in work efficiency, and perform sorting work accurately and efficiently. Further, for example, by setting a stop time adapted to the characteristics of the operator (e.g., work speed) or the characteristics of the goods (e.g., category (e.g., textiles, clothes, small items, fragile items, food and beverages)), it is possible to prevent transportation errors and a decrease in work efficiency, and perform sorting work accurately and efficiently.

[0008] Although the present invention belongs to the category of systems, the same effects can also be achieved by methods and programs. Advantages of the Invention

[0011] Hereinafter, a mode for implementing the present invention (hereinafter referred to as an embodiment) will be described in detail with reference to the drawings. In the following figures, the same elements are denoted by the same numerals or symbols in the overall description of the embodiment. It should be noted that the premise of this specification is that the transportation control system 1 is a system that transports goods in a warehouse or the like by a transport vehicle.

[0012] [Overview of the Transportation Control System 1] Figure 1 It is a schematic diagram for explaining the overview of the transportation control system 1. Based on Figure 1 , the structure of the transportation control system 1 will be described. The transportation control system 1 is a system that at least includes a WCS (Warehouse Control System) 2 and a sorting device 3. The WCS 2 is a system for controlling material transportation equipment and IoT devices in a warehouse. The material transportation equipment is, for example, a forklift, a loading device such as a case packing / unpacking system, an automatic guided vehicle (AGV), an overhead suspension conveyor, a transportation device equipped with an AI (Artificial Intelligence) type automatic transportation robot, a conveyor belt, a sorting device for a sorter, a storage device such as an automated warehouse, a digital picking system, a shipping device such as an automatic carton forming machine. In this specification, the transportation device and the sorting device are collectively referred to as the sorting device. The WCS 2 includes a computer 10 with server functions, and this computer 10 can be implemented by, for example, one computer, or like a cloud computer, by multiple computers. This computer 10 executes various processes performed by the WCS 2. The cloud computer in this specification can be a computer that can be expandably used with any computer when completing a specific function, or a computer that includes multiple functional modules and freely combines and uses its functions to implement a certain system. The sorting device 3 includes a transport vehicle 4 and a transport path 5. The transport vehicle 4 transports the goods loaded by the operator from the starting position (for example, an inductive conveyor) to the target position (for example, each chute assigned a transportation destination). The transport vehicle 4 is, for example, a vehicle-type conveyor (such as an AGV) that travels on the transport path 5 described later. The transport vehicle 4 transports the goods loaded by the operator at the starting position to the target position of the transport path 5. The transport path 5 is a path for transporting goods in a warehouse. The transport path 5 has multiple branches for the transport vehicle 4 to travel, and each of the multiple branches has a target position. This target position corresponds to the outlet of the sorting device for distributing goods. In the figure, this target position is represented by a white circle. In addition, the transport path 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 to transport the goods loaded by the operator from the starting position to the target position will be described.

[0014] The computer 10 sets the stop time for the conveyance vehicle 4 to stop at the starting position (step S1). The starting position is, for example, the position where the operator performs the operation of loading the goods onto the conveyance vehicle 4 (e.g., an inductive conveyor). The stop time is the time required for the operator to perform the operation of loading the goods onto the conveyance vehicle 4. The computer 10 sets the stop time for each operator based on specified conditions. The specified conditions are, for example, predefined times, actual values of the operations of each operator (e.g., the time required for each operator's past operations), and the operation efficiency of the operations of each operator (e.g., the efficiency calculated based on the time required for the operation and their working speed).

[0015] After the operator starts the operation, the computer 10 causes the conveyance vehicle 4 to stop at the starting position until the set stop time has elapsed (step S2). The computer 10 starts counting the set stop time based on the identification code of the operator, the image of the operation status taken, etc. That is, the computer 10 starts counting the stop time after the operator starts the operation. During this stop time, the operator loads the goods onto the conveyance vehicle 4. When the computer 10 determines that the set stop time has elapsed, it instructs the conveyance vehicle 4 to transport the loaded goods. That is, after the operator starts the operation, the computer 10 causes the conveyance vehicle 4 to stop at the starting position until the set stop time has elapsed. After this stop time ends, the computer 10 instructs the conveyance vehicle 4 to transport the loaded goods.

[0016] The above is the outline of the conveyance control system 1. According to this conveyance control system 1, conveyance errors and a decline in operation efficiency can be prevented, and sorting work can be performed accurately and efficiently.

[0017] [Device Structure] Figure 2 It is a block diagram showing the structure of the conveyance control system 1. The conveyance control system 1 is a system that controls the conveyance vehicle 4 to transport the goods loaded by the operator from the starting position to the target position, and is composed of at least the WCS 2 and the sorting device 3 (the conveyance vehicle 4 and the conveyance path 5). In the conveyance control system 1, each of the WCS 2 and the sorting device 3 is connected in a manner capable of data communication via a network 7 such as a common line network or an intranet. It should be noted that the structure of the transportation control system 1 is only an example, and for terminals and devices not shown, etc., the quantity, type, and function thereof can be appropriately changed.

[0018] As described above, the WCS 2 is a system for controlling material transportation equipment and IoT devices in a warehouse. As described above, the WCS 2 system includes a computer 10 having a server function for performing various processes. The computer 10 is equipped with a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc. as a control unit, and also has a device capable of communicating with other terminals and devices, etc. as a communication unit, and a stop unit 11 for stopping the transport vehicle 4 at the departure position until a set stop time after the operator starts the operation. The computer 10 is equipped with a data storage unit such as a hard disk, a semiconductor memory, a recording medium, a memory card, etc. as a recording unit. The computer 10 is equipped with various devices for performing various processes as a processing unit, a setting unit 12 for setting the stop time for stopping the transport vehicle 4 at the departure position, etc.

[0019] In the computer 10, the control unit realizes a transport instruction module, a stop module, an operation content information acquisition module, and a cargo information acquisition module by reading a predetermined program and cooperating with the communication unit. In addition, in the computer 10, the control unit realizes a setting result recording module, a determination result recording module, and a change result recording module by reading a predetermined program and cooperating with the recording unit. In addition, in the computer 10, the control unit realizes a setting module, an operation content determination module, a stop time determination module, a change module, a timing module, and a determination module by reading a predetermined program and cooperating with the processing unit.

[0020] As described above, the transport vehicle 4 transports the goods loaded by the operator from the departure position (for example, an inductive conveyor) to the target position (for example, each chute assigned as the transport destination). The transport vehicle 4 is, for example, a transport device such as a vehicle-type conveyor (such as an AGV) traveling on the transport path 5. In the present embodiment, the transport vehicle 4 is described as a vehicle-type conveyor. Based on instructions from the WCS2, etc., the transporter 4 performs actions such as stopping at the departure position and traveling on the transportation path 5. The transporter 4 travels to the departure position, and the operator loads the goods. The transporter 4 stops at the departure position based on the stop time set by the WCS2. After passing this stop time, the transporter 4 travels to the designated target position while loaded with the goods and drops the loaded goods at the target position. After dropping the goods, the transporter 4 travels to a designated position (e.g., the departure position). It should be noted that the transporter 4 is merely an example, and the transportation unit in the present invention is not limited to the transporter 4.

[0021] As described above, the transportation path 5 is a path for transporting goods in the warehouse, has multiple branch lines for the transporter 4 to travel, and each of the multiple branch lines has a target position. In addition, the transportation path 5 has a departure position for the transporter 4, where the operator loads the goods onto the transporter 4. The transportation path 5 is, for example, a sorting device such as a conveyor belt. In the present embodiment, the transportation path 5 is described as a conveyor belt. The transportation path 5 is composed of a main line and multiple branch lines connected to the main line (refer to Figure 3 ). Each of the multiple branch lines of the transportation path 5 has one or more target positions. As described above, the target position corresponds to the outlet of the sorting device for distributing commodities. In addition, the transportation path 5 has a departure position for the transporter 4 on one main line.

[0022] Based on Figure 3 , the sorting device 3 is described. This figure is a diagram schematically showing an example of the sorting device 3. In this figure, as the sorting device 3, the transporter 4 and the transportation path 5 are shown. The transportation path 5 is composed 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 is provided with an inductive conveyor 25, which is the departure position of the transporter 4, the position where the operator performs operations, and the position where the goods are loaded onto the transporter 4. The structure of the first branch line 21 is rectangular, and five chutes 24, which are the target positions of the transporter 4, are provided on one side of the long side, and five chutes 24, which are the target positions of the transporter 4, are provided on the other side of the long side. Similarly, the structures of the second branch line 22 and the third branch line 23 are also rectangular, and five chutes 24, which are the target positions of the transporter 4, are provided on one side of the long side, and five chutes 24, which are the target positions of the transporter 4, are provided on the other side of the long side. The transporter 4 departs from the inductive conveyor 25, travels along the transportation path 5 towards one of the chutes 24, and transports the goods. It should be noted that the above transportation path 5 is only an example, and the transportation path in the present invention is not limited to Figure 3 the shown transportation path 5. Additionally, similarly, regarding the positions, quantities, and other details of the chute 24 and the inductive conveyor 25 etc. provided in the transportation path 5, they are also not limited to Figure 3 the shown details.

[0023] Hereinafter, various processes executed by the transportation control system 1 will be described in conjunction with the processes executed by the above-mentioned respective modules. In this specification, each module can execute the content of its processing as a function it inherently has, or can execute it through a specified application.

[0024] [Setting Process Executed by Computer 10] Based on Figure 4 , the setting process executed by computer 10 will be described. This figure is a diagram showing the flowchart of the setting process executed by computer 10. This setting process is the detailed content of the setting process (step S1) for setting the stop time for the above-mentioned transportation vehicle 4 to stop at the departure position.

[0025] The setting module sets the stop time for the transportation vehicle 4 to stop at the starting position (step S10). As described above, the departure position is the inductive conveyor 25 where the operator performs the operation of loading goods onto the transportation vehicle 4 (hereinafter also simply referred to as the operation). The stop time is the time required for the operator to complete the work. The setting module sets the stop time for each operator. The setting module sets the stop time based on any one or more combinations of a predefined time, the actual value of each operator's operation, the operation efficiency of each operator's operation, etc. The actual value is the time required for each operator to perform the operation in the last or previous time. The operation efficiency is calculated based on the time required for the operator to perform the operation and their working speed. When the setting module sets the stop time based on a predefined time, that time is set as the stop time for each operator. When the setting module sets the stop time based on the actual value of each operator, the time of the actual value itself of each operator, the time obtained by increasing or decreasing the actual value by a specified time, the average value time of the actual value, the longest time of the actual value, the shortest time of the actual value, etc. are set as the stop time for each operator. It should be noted that the setting module can use the actual value as teacher data, perform relevant learning on the stop time required for each operator's operation through machine learning, etc., and set the stop time based on the learning result. When the setting module sets the stop time based on the work efficiency of each operator, the time that best matches the work efficiency of each operator is calculated, and the calculated time is set as the stop time for each operator.

[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 operator in association with the identification code of that operator.

[0027] The above is the setting process. The transportation control system 1 uses the stop time set through the above setting process for the subsequent processes described below.

[0028] [Stop process executed by computer 10] Based on Figure 5 , the stop process executed by computer 10 will be described. This figure is a diagram showing the flowchart of the stop process executed by computer 10. This stop process is the detailed content of the stop process (step S2) before the start of the operation. After the operator starts the operation, the above-mentioned transport vehicle 4 is stopped at the departure position until the set stop time has elapsed. This stop process is a process performed after the above setting process.

[0029] The transportation instruction module instructs the transport vehicle 4 to travel to the departure position (step S20). The transportation instruction module sends an instruction to the transport vehicle 4 to travel to the departure position. The transport vehicle 4 receives this instruction. Based on this instruction, the transport vehicle 4 travels to the departure position.

[0030] The stop module instructs the transport vehicle 4 to stop at the departure position (step S21). When the transport vehicle 4 reaches the departure position, the stop module sends an instruction to the transport vehicle 4 to stop at the departure position. The transport vehicle 4 receives this instruction. Based on this instruction, the transport vehicle 4 stops at the departure position.

[0031] The above is the stop process. The transportation control system 1 performs the subsequent processes described below on the transport vehicle 4 that is in a stopped state due to the above stop process.

[0032] [Determination process executed by computer 10] Based on Figure 6 , the determination process executed by computer 10 will be described. This figure is a diagram showing the flowchart of the determination process executed by computer 10. This determination process is a process performed after the above setting process.

[0033] The operation content information acquisition module acquires operation content information regarding the operation content of the operator (step S30). The operation content of the operator refers to the operator performing operations at the departure position and the operation status. The operation content information is the information required to determine the operator performing operations at the departure position and the operation status. For example, it is the operator information (such as an identification code) of the operator and the image around the departure position. The operation content information acquisition module acquires the operator information of the operator performing operations at the departure position from a computer or the like that manages shift data, etc. In addition, a photographing device such as a camera is provided near the departure position, and the operation content information acquisition module acquires the image of the operator performing operations around the departure position and the image of the situation around the departure position taken by it. The computer, the photographing device, etc. send the above information and images to the computer 10 as operation content information. The operation content information acquisition module acquires operation content information regarding the operation content of the operator by receiving this information.

[0034] The operation content determination module determines the operation content based on the acquired operation content information (step S31). The operation content determination module analyzes the acquired operation content information, etc., and determines the operation content performed at the current start position. The operation content determination module determines the operator based on the identification code of the operator in the operation content information. In addition, the operation content determination module determines the operator and the status of the goods, etc. shown in the image based on the image in the operation content information. As a result, the operation content determination module determines the identification code of the operator performing the operation and whether the operator has started the operation.

[0035] The stop time determination module determines the stop time based on the determined operation content (step S32). The stop time determination module determines the stop time based on the operator in the determined operation content. Through the above setting process, the stop time determination module determines the stop time suitable for the currently determined operator.

[0036] The determination result recording module records the determined stop time (step S33). The determination result recording module records the determined stop time in association with the currently determined operation content.

[0037] The above is the determination process. The transportation control system 1 uses the stop time determined through the above determination process to perform the subsequent processes.

[0038] [Change process executed by computer 10] Based on Figure 7 , the change process executed by the computer 10 will be described. This figure is a flowchart showing the change process executed by the computer 10. This change process is a process executed after the above-mentioned determination process.

[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 on the transport vehicle 4, such as an identification code, name, category, quantity, and destination of transportation. When the operator loads the cargo onto the transport vehicle 4, the operator uses a scanner to read the cargo information of the cargo. The scanner sends the read cargo information of the cargo to the computer 10. The cargo information acquisition module acquires the cargo information about the cargo to be loaded by receiving the cargo information.

[0040] The change module changes the stop time according to the acquired cargo information (step S41). The change module changes the stop time according to the category in the acquired cargo information. The change module changes the stop time based on the preliminary evaluation results of the loading difficulty of each category of cargo. The higher the evaluation, the easier it is to load the cargo. The change module changes the stop time of the cargo with a higher evaluation (relatively easy to load) to be shorter, and changes the stop time of the cargo with a lower evaluation (relatively difficult to load) to be longer. It should be noted that the change module can not only shorten or extend the stop time by a specified time, but also not change the stop time. That is, the change module selects an appropriate one from adding a specified time to the stop time, subtracting a specified time from the stop time, or neither adding nor subtracting, and changes the stop time based on the selected result. For example, when the cargo is a category that is easy to load onto the transport vehicle 4 (e.g., small items), the change module shortens the stop time by 1 second; when the cargo is a category that is not easy to load onto the transport vehicle 4 (e.g., fragile items), the stop time is extended by 1 second; when the cargo is a category that is neither difficult nor easy to load onto the transport vehicle 4 (e.g., food and beverages), the stop time is not changed. It should be noted that the change module can also change the stop time according to cargo information other than the category. In this case, the change module can change the stop time according to the loading difficulty of the cargo in the cargo information. In addition, although in the process of step S41, the change module uses the results of the pre-evaluated loading difficulty to change the stop time, it can also change the stop time based on other methods.

[0041] The change result recording module records the changed stop time (step S42). The change result recording module records the changed stop time in association with the identification code of the operator associated with the stop time before the change.

[0042] The above is the change processing. The transportation control system 1 executes the following processing using the stop time changed by the above change processing. It should be noted that it is not necessarily required to execute the above change processing. In the case where this change processing is not executed, the transportation control system 1 can execute this processing using the stop time set by the above setting processing in the following transportation instruction processing.

[0043] [Transportation Instruction Processing Executed by Computer 10] Based on Figure 8 , the transportation instruction processing executed by the computer 10 will be described. This figure is a flowchart showing the transportation instruction processing executed by the computer 10. This transportation instruction processing is the detailed content of the stop processing (step S2) that causes the above-mentioned transport vehicle 4 to stop at the departure position before the set stop time after the operator's operation starts. This transportation instruction processing is executed after the above change processing.

[0044] The timing module starts timing the stop time according to the acquired operation content information (step S50). The timing module starts timing the stop time according to the operation content of the operator specified based on the acquired operation content information. When the operation content of the operator matches the start of the operator's operation, the timing module starts timing this stop time. During the stop time, the operator loads the goods onto the transport vehicle 4. After starting the timing, due to the above stop processing, the transport vehicle 4 continues to stop.

[0045] The determination module determines whether the stop time has elapsed (step S51). The stop time used by the determination module for determination is the stop time changed by the above change processing. It should be noted that in the case where the change processing is not executed, it is the stop time set by the above setting processing. In the case where the determination module determines that the stop time has not elapsed (step S51 No), the computer 10 repeats this processing. At this time, due to the above stop processing, the transport vehicle 4 continues to stop and remains stopped at the departure position.

[0046] On the other hand, in the case where the determination module determines that the stop time has elapsed (step S51 Yes), the transportation instruction module instructs the transport vehicle 4 to transport the goods (step S52). The transportation instruction module sends an instruction to transport the goods to the transport vehicle 4. The transport vehicle 4 receives this instruction. When receiving the instruction, the transport vehicle 4 releases the stopped state and travels to the target position at the transport destination where the goods are assigned. After arriving at the target position, the transport vehicle 4 unloads the loaded goods. After unloading the goods, the transport vehicle 4 travels to the designated position.

[0047] The above is the transport instruction process.

[0048] Although each of the above processes is described as a separate process, the computer 10 may also be configured to be able to combine and execute part or all of the above processes. In addition, the computer 10 may also be configured to be able to execute the process even at times other than the above times in each process.

[0049] The above methods and functions are realized by a computer (including a CPU, an information processing device, and various terminals) reading and executing a predetermined program. For example, the program may be provided in a manner of being provided from a computer via a network (SaaS: Software as a Service) or a cloud service. In addition, the program may be provided in a manner of being recorded in a computer-readable recording medium. In this case, the computer reads the program from the recording medium, transfers the program to an internal recording device or an external recording device, records and executes the program. In addition, the program may also be pre-recorded in a recording device (recording medium) and provided to the computer from the recording device via a communication line.
