In the present embodiment, the machine tool M will be described as n units of machine tools 1 to n. Further, the type of each machine tool M is not limited and is arbitrary. For example, each machine tool M is a multi-tasking machine including a laser machining machine, a lathe, a machining center, a punch press, a press brake, a laser machining device, and a punch press. Each machine tool M is wirelessly or wiredly connected to the control unit 4 of the parts management system 1 so as to be able to communicate with each other. Each machine tool M can exchange various types of information with the control unit 4. When there are a plurality of machine tools M, the machine tools M may be of the same type or different types of each other. Further, the installation location of each machine tool M is arbitrary. For example, each machine tool M may not be arranged in the same building but may be arranged in a plurality of different buildings.

The replacement part T is, for example, a machining tool (tool) or a consumable item used in the machine tool M. The type of the replacement part T is not limited and is arbitrary. For example, a processing tool is a processing tool used for cutting, cutting, grinding, forming, and the like. For example, the machining tool is a cutting tool such as a laser or a saw, a cutting tool such as a drill or a cutting tool, a grinding tool such as a grinding wheel, a forming tool such as a mold, or the like. The consumables are, for example, various consumables used in the machine tool M. For example, consumables include bolts, nuts, pipes, screws, gears, O-rings, belts, chucks, various parts such as motors, filters, lubricating oils, and the like. The replacement part T may be other than a machining tool or a consumable, and may be, for example, a program (recording medium including the program) used for controlling and managing the machine tool M, or a workpiece used for machining by the machine tool M.

The machine tool M includes a mechanism for managing the replacement part T. The machine tool M includes a control device that controls and manages the machine tool M, and manages the replacement part T by the control device. The machine tool M manages the replacement timing (life) of the replacement part T based on, for example, historical information such as the usage period of the replacement part T, the number of times of use (the number of hits), and information indicating a failure of the replacement part T. do. For example, the machine tool M replaces the replacement part T when the usage period (number of times of use) of the replacement part T exceeds a preset threshold value or when it detects information indicating a failure of the replacement part T.

The lock control unit 23 may not be provided.

The storage list generation unit 24 updates the storage list D3. The storage list generation unit 24 stores, for example, information regarding storage of the replacement part T of the storage location P input from the input unit 12 or the like (eg, storage location, type of replacement part T, number of acquired replacement parts T, storage). The storage list D3 is updated based on the number of replacement parts T and the information indicating the completion of storage of the replacement parts T in the storage location. The storage list generation unit 24 may not be provided.

Next, the parts management method according to the present embodiment will be described based on the above-described parts management system 1 of the present embodiment. FIG. 5 is a flowchart showing the operation of the parts management system 1 of the present embodiment. In the following description, FIGS. 1 to 4 will be referred to as appropriate.

In step S1, the plurality of machine tools M each produce a product. In step S2, the replacement request information D1 (see FIG. 2A) is sent (transmitted) from the machine tool M to the parts management system 1. When the machine tool M determines that it is time to replace the replacement part T, the machine tool M generates replacement request information D1. The machine tool M notifies the outside by outputting information regarding a replacement request such as "Please replace the replacement part T1" to the display device 6 (see FIG. 1). As a result, the worker U knows that the replacement part T has a replacement request from the machine tool M. The machine tool M outputs the generated replacement request information D1 to the parts management system 1.

In step S3, the part selection unit 21 (see FIG. 1) selects the target replacement part T from the storage list D3 based on the replacement request information D1 sent from the machine tool M. The exchange request information D1 is stored in the storage unit 20 by the control unit 4 as an exchange request list D2. The component selection unit 21 selects information on the target replacement components T1 to Tn and its storage locations P1 to Pn from the storage list D3 based on the replacement request list D2.

In step S4, the notification instruction unit 22 (see FIG. 1) notifies the notification unit 3 of the storage location P of the target replacement component T selected by the component selection unit 21. For example, when the component selection unit 21 selects information on the target replacement component T1 and its storage location P1 from the storage list D3 (see FIG. 4), the notification instruction unit 22 will perform the notification unit 22 as described above. 3 is instructed to execute any of lighting, extinguishing, and blinking of the lighting device 15 arranged in the storage location P1.

In step S5, the notification unit 3 (see FIG. 1) notifies each storage location P of the plurality of replacement parts T under the control of the notification instruction unit 22. For example, as described above, the notification unit 3 turns on, turns off, and turns on / off the lighting device 15 indicating the storage location P of the target replacement part T among the lighting devices 15 under the control of the notification instruction unit 22. Alternatively, either blinking is executed (see FIG. 3). For example, as described above, the notification unit 3 lights or blinks the lighting device 15 indicating the storage location P of the target replacement part T among the lighting devices 15. As a result, the storage location P in which the target replacement part T is stored is notified. The worker U can know the storage location P in which the target replacement part T is stored by the notification by the notification unit 3. As described above, in the parts management system 1 of the present embodiment, the storage location P in which the target replacement part T is stored is automatically notified based on the replacement request information D1 sent from the machine tool M. When the worker U acquires the replacement part T, the labor and time for searching the storage location P of the worker U can be suppressed. Further, the notification unit 3 has a plurality of lighting devices 15 provided in the storage unit 2 so as to indicate the storage locations P of the plurality of replacement parts T, and the notification unit 22 is the target of the plurality of lighting devices 15. When the lighting device 15 indicating the storage location P of the replacement part T is turned on or blinks, the storage location P can be reliably notified with a simple configuration.

In step S6, the lock control unit 23 (see FIG. 1) unlocks the lock mechanism 9 of the storage location P of the target replacement component T selected by the component selection unit 21, and the storage location of the target replacement component T. Instruct (control) to lock the lock mechanism 9 of the storage location P other than P. In step S7, the lock mechanism 9 unlocks the door 8 of the storage location P of the target replacement part T under the control of the control unit 4. As a result, since the worker U can access only the target replacement part T, it is possible to prevent the worker U from acquiring the replacement part T by mistake, and it is possible to improve the security. For example, when the target replacement part T1 is stored in the storage location P1 as in the example of FIG. 1, the lock mechanism 9 unlocks the lock mechanism 9 in the storage location P1 under the control of the lock control unit 23. The lock mechanism 9 of the storage location P other than the storage location P1 is locked. As a result, the worker U can open the door 8 of the storage location P1 in which the target replacement part T1 is stored and acquire the target replacement part T1.

In step S8, the worker U opens the door 8 of the storage location P in which the replacement part T of the target notified by the notification unit 3 is stored, and acquires the replacement part T of the target.

In step S9, the storage unit 2 transmits information (acquisition completion information) indicating the completion of acquisition of the replacement part T from the storage location P by the worker U to the control unit 4. For example, the worker U inputs an operation command for transmitting acquisition completion information to the control unit 4 by the input unit 12 of the storage unit 2. The storage unit 2 transmits acquisition completion information to the control unit 4 based on the above operation command. Further, the worker U inputs information such as the type and number of the acquired replacement parts T by the input unit 12 of the storage unit 2. The storage unit 2 transmits the input information by the worker U to the control unit 4.
