Summary of the Invention

Problems to be Solved by the Invention

[0006] When the reel storage shelf receives the above-mentioned parts shortage notice, the reel storage shelf can identify the parts storage section that stores the parts reel of the corresponding electronic component and light up the display element of that parts storage section. However, when parts shortage notices are received sequentially for a plurality of parts, if the display elements of the plurality of parts storage sections are similarly lit, it is difficult for the operator to determine the priority order in which the electronic components should be replenished.

Modes for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant descriptions are omitted.

[0021] <Overview of the Component Management System> One embodiment of the present invention relates to a component management system for managing electronic components. First, with reference to FIG. 1, an overview of the component management system according to one embodiment of the present invention will be described.

[0022] FIG. 1 is an explanatory diagram showing a component management system according to one embodiment of the present invention. As shown in FIG. 1, the component management system according to one embodiment of the present invention includes a component mounting device 10 and a reel storage shelf 20.

[0023] The component mounting device 10 and the reel storage shelf 20 are communicably connected via a network 12. The network 12 is a wired or wireless transmission path for information transmitted from a device connected to the network 12. For example, the network 12 may include a public line network such as the Internet, a telephone line network, a satellite communication network, various LANs (Local Area Networks) including Ethernet (registered trademark), WANs (Wide Area Networks), etc. Further, the network 12 may include a dedicated line network such as an IP-VPN (Internet Protocol-Virtual Private Network).

[0024] (Component Mounting Device 10) The component mounting device 10 is a device for mounting electronic components on a substrate. The component mounting device 10 includes a plurality of feeders, and component reels each containing different types of electronic components are set on each of the plurality of feeders. The component mounting device 10 mounts the electronic components contained in the component reels on the substrate via the feeders.

[0025] The component mounting device 10 transmits component shortage-related information that warns of the depletion of the electronic components stored in the component reel to the reel storage shelf 20 according to the remaining quantity of the electronic components. For example, the component mounting device 10 may transmit the component shortage-related information about the electronic components whose remaining quantity has fallen below a predetermined number to the reel storage shelf 20. The component shortage-related information may include, in addition to the information indicating the target electronic components, the predicted component shortage time, which is the time when the electronic components are expected to run out. The component mounting device 10 can calculate the predicted component shortage time in consideration of the number of each electronic component used in the process being executed or planned to be executed.

[0026] Note that the component mounting device 10 is an example of an external device connected to the reel storage shelf 20. Another type of external device where electronic components are used or consumed may constitute a component management system in place of the component mounting device 10.

[0027] (Reel storage shelf 20) The reel storage shelf 20 stores a plurality of component reels. When the reel storage shelf 20 receives the component shortage-related information from the component mounting device 10, the operator can take out the component reel that houses the electronic components indicated by the component shortage-related information from the reel storage shelf 20 and replace it with the component reel set in the component mounting device 10 to replenish the electronic components. Such a reel storage shelf 20 has a storage shelf body 210 and a component management device 220.

[0028] The storage shelf body 210 includes a pair of side frames 211, a plurality of mounting shelves 212, a top panel 213, and a plurality of casters 214.

[0029] The pair of side frames 211 extends along the vertical direction with respect to the mounting surface of the storage shelf body 210. The plurality of mounting shelves 212 are installed at different height positions between the pair of side frames 211. The top panel 213 connects between the upper ends of the pair of side frames 211. The casters 214 support the storage shelf body 210 so as to be movable.

[0030] A plurality of component storage parts C are arranged on each mounting shelf 212. A component reel P is stored in each component storage part C. The component reels P stored in each component storage part C can accommodate different electronic components. Each component reel P is accommodated in a state where a tape such as a paper tape with a plurality of electronic components attached thereto or an embossed tape formed by setting electronic components in a plurality of recesses is wound thereon.

[0031] In addition, a display element D is provided in each component storage part C. The display element D may be an LED (Light Emitting Diode) lamp that lights up or blinks in various colors. However, the display element D is an example of the first notification part, and a speaker that outputs sound or voice may be provided in each component storage part C instead of or in addition to the display element D.

[0032] The storage shelf body 210 described above can also be said to be a higher-level storage part for the component storage parts C in that it has a plurality of component storage parts C.

[0033] (Component management device 220) The component management device 220 stores information on the electronic components stored in the storage shelf body 210. Further, when the component management device 220 receives component shortage-related information from the component mounting device 10, it identifies the component storage part C that stores the electronic component targeted by the component shortage-related information, and controls the execution of a notification indicating the component storage part C. For example, the component management device 220 causes the display element D provided in the identified component storage part C to start displaying. In particular, the component management device 220 according to an embodiment of the present invention changes the mode of the above notification according to the passage of time. Hereinafter, the configuration and operation of such a component management device 220 will be sequentially described in detail.

[0034] <Configuration of component management device 220> FIG. 2 is an explanatory diagram showing the configuration of the component management device 220 according to an embodiment of the present invention and each component storage unit Cj (j = 1, 2,...). In addition to the above-described display element Dj, a sensor Ej is provided in each component storage unit Cj. The sensor Ej detects whether a component reel P is stored in the component storage unit Cj, whether a component reel P is stored in the component storage unit Cj, and whether the component reel P has been taken out from the component storage unit Cj. The sensor Ej may be, for example, a sensor that uses magnetic force.

[0035] As shown in FIG. 2, the component management device 220 includes an operation display unit 222, a component management unit 223, a communication unit 224, a time management unit 225, and a control unit 226.

[0036] (Operation display unit 222) The operation display unit 222 has a function as an operation unit that receives operations by an operator and a function as a display unit that displays information. However, the function as an operation unit and the function as a display unit may be realized separately. For example, the operation display unit 222 displays an input screen for the operator to input which component storage unit C stores the component reel P of which electronic component. When the operator stores the component reel P in the component storage unit C, the operator can operate the operation display unit 222 to input on the input screen which component storage unit C stores the component reel P of which electronic component. Alternatively, the operator may input the component information of the component reel P on the input screen by reading the barcode attached to the component reel P with a barcode reader (input device). After that, when the operator stores the component reel P in the component storage unit C, the sensor Ej detects which component storage unit Cj the component reel P is stored in, so the component management unit 223 can link and manage the component information of the component reel P read from the barcode first and the component storage unit Cj in which the component reel P is stored.

[0037] (Component management unit 223) The component management unit 223 is an example of a component information storage unit that stores information (component information) of electronic components stored in each of the plurality of component storage units C. The component management unit 223 stores the component information input by the operator into the operation display unit 222, and deletes the component information based on the detection by the sensor E that the component reel P has been taken out.

[0038] FIG. 3 is an explanatory diagram showing a specific example of the component information stored in the component management unit 223. As shown in FIG. 3, in the component information, information indicating the component storage unit C, the component management number, and the component quantity are associated. For example, information indicating the component storage unit C1 is associated with the component management number "PARTS-001" and the component quantity "2000". This indicates that a component reel P containing "2000" electronic components with the component management number "PARTS-001" is stored in the component storage unit C1. Also, information indicating the component storage unit C3 is associated with "empty" as the component management number and the component quantity. This indicates that no component reel P is stored in the component storage unit C3 and the component storage unit C3 is in an empty state.

[0039] (Communication unit 224) Returning to the description of the component management device 220 with reference to FIG. 2, the communication unit 224 has a function as a receiving unit that receives various information from the component mounting device 10. For example, the communication unit 224 receives component shortage-related information from the component mounting device 10.

[0040] (Time management unit 225) The time management unit 225 is an example of a predicted time storage unit that stores a predicted time (component shortage predicted time) at which it is predicted that the electronic component targeted by the component shortage-related information received by the communication unit 224 will experience component shortage in the component mounting device 10. Based on control from the control unit 226, the time management unit 225 stores the component shortage predicted time in association with information indicating the component storage unit C that stores the electronic component indicated by the component shortage-related information.

[0041] FIG. 4 is an explanatory diagram showing a specific example of the predicted time of component shortage. In the example shown in FIG. 4, the predicted time of component shortage "2023 / 9 / 19 12:00:00" is associated with the information indicating the component storage unit C1. This means that it is predicted that the electronic components of the component reel P stored in the component storage unit C1 will run out of components at "2023 / 9 / 19 12:00:00" in the component mounting apparatus 10. Also, no predicted time of component shortage is associated with the information indicating the component storage unit C2. This means that no component shortage-related information has been received for the electronic components of the component reel P stored in the component storage unit C2.

[0042] When the predicted time of component shortage is included in the component shortage-related information, the time management unit 225 stores the predicted time of component shortage. When the predicted time of component shortage is not included in the component shortage-related information, the time management unit 225 may store the time after a predetermined time from the reception of the component shortage-related information as the predicted time of component shortage.

[0043] (Control unit 226) Returning to the description of the component management apparatus 220 with reference to FIG. 2, the control unit 226 controls all operations in the component management apparatus 220. For example, the control unit 226 causes the component management unit 223 to store the component information input to the operation display unit 222. Also, based on the reception of the component shortage-related information by the communication unit 224, the control unit 226 identifies the component storage unit C that stores the electronic components targeted by the component shortage-related information, and associates the predicted time of component shortage with the information indicating the identified component storage unit C and stores it in the time management unit 225.

[0044] Further, the control unit 226 controls the execution of a notification indicating the component storage unit C that stores the electronic components targeted by the component shortage-related information. In particular, the control unit 226 changes the mode of the above notification as time elapses. For example, the control unit 226 causes the display element D provided in the component storage unit C in which the predicted time of component shortage is stored in association with the time management unit 225 to be displayed in a display pattern according to the remaining time until the predicted time of component shortage.

[0045] FIG. 5 is an explanatory diagram showing a specific example of the relationship between the remaining time and the display pattern. In the illustrated example, the remaining time "10 minutes or more" and the display pattern "red light on" are associated. Also, in the illustrated example, the remaining time "5 minutes or more and less than 10 minutes" and the display pattern "red flashing at long intervals" are associated. Further, in the illustrated example, the remaining time "2 minutes or more and less than 5 minutes" and the display pattern "red flashing at medium intervals" are associated. Additionally, in the illustrated example, the remaining time "0 minutes or more and less than 2 minutes" and the display pattern "red flashing at short intervals" are associated. Moreover, in the illustrated example, the remaining time "exceeding the predicted time" and the display pattern "red and green reversing at short intervals" are associated.

[0046] Based on such a relationship between the remaining time and the display pattern, the control unit 226 identifies the display pattern corresponding to the remaining time until the predicted time of out-of-stock of parts, and causes the display element D to perform display in the identified display pattern.

[0047] In the case where there are a plurality of component storage units C that store the electronic components targeted by the out-of-stock related information, the control unit 226 may associate the predicted time of out-of-stock of parts with the information indicating any one of the plurality of component storage units C and store it in the time management unit 225. For example, the control unit 226 may associate the predicted time of out-of-stock of parts with the information indicating the component storage unit C randomly selected from the plurality of component storage units C and store it in the time management unit 225. Or, when the component information stored in the component management unit 223 includes the information of the purchase date, the predicted time of out-of-stock of parts may be associated with the component storage unit C that houses the component reel P with the oldest purchase date and stored in the time management unit 225.

[0048] Further, when there are a plurality of component storage units C that store the electronic components targeted by the component shortage-related information, the control unit 226 may associate the component shortage prediction time with the information indicating each of the plurality of component storage units C and store it in the time management unit 225. In this case, the display elements D of the plurality of component storage units C start to be displayed, and when the component reel P is taken out from any one of the component storage units C, the display elements D of the plurality of component storage units C end the display. In this case, the operator can take out the component reel P from the component storage unit C that is easily accessible among the plurality of component storage units C.

[0049] <Operation> Above, the configuration of the component management device 220 according to an embodiment of the present invention has been described. Subsequently, with reference to FIGS. 6 and 7, the operation of the component management device 220 according to an embodiment of the present invention will be organized.

[0050] FIG. 6 is a flowchart showing the operation from the reception of the component shortage-related information to the start of the display by the display element D. FIG. 7 is a flowchart showing the operation after the start of the display by the display element D.

[0051] As shown in FIG. 6, first, when the communication unit 224 receives the component shortage-related information from the component mounting device 10 (S304), the control unit 226 refers to the component management unit 223 and determines whether the storage shelf main body 210 stores the component reel P of the target component (S308).

[0052] If it is determined in S308 that the storage shelf main body 210 does not store the component reel P of the target component (S308 / No), the control unit 226 causes the operation display unit 222 to display that the component reel P is not stored (S312), and the operation ends.

[0053] If it is determined in S308 that the storage shelf main body 210 stores the component reel P of the target component (S308 / Yes), the time management unit 225 associates the component shortage prediction time with the information indicating the component storage unit C that stores the component reel P and stores it (S316).

[0054] Subsequently, the time management unit 225 calculates the remaining time until the predicted part depletion time (S320). Thereafter, the time management unit 225 controls the display of the display element D in a display pattern corresponding to the calculated remaining time (S324).

[0055] Then, as shown in FIG. 7, the control unit 226 determines whether or not the removal of the component reel P from the component storage unit C whose predicted part depletion time is stored in the time management unit 225 is detected by the sensor E (S404).

[0056] When the control unit 226 determines that the removal of the component reel P from the component storage unit C is detected by the sensor E (S404 / Yes), it deletes the component information associated with the component storage unit C and the component management unit 223, turns off the display element D of the component storage unit C, and deletes the predicted part depletion time associated with the component storage unit C and the time management unit 225 (S408).

[0057] When the control unit 226 determines in S404 that the removal of the component reel P from the component storage unit C is not detected by the sensor E (S404 / No), it refers to the predicted part depletion time associated with the component storage unit C and the time management unit 225 and calculates the remaining time until the predicted part depletion time (S412).

[0058] Then, the control unit 226 determines whether or not the predicted part depletion time has already exceeded a certain time (S416). When the control unit 226 determines that the predicted part depletion time has already exceeded a certain time (S416 / Yes), it turns off the display element D of the component storage unit C and deletes the predicted part depletion time associated with the component storage unit C and the time management unit 225 (S420).

[0059] When the predicted time of component shortage has not exceeded a certain time period (S416 / No), the control unit 226 controls the display of the display element D in a display pattern corresponding to the remaining time calculated in S412 (S424). For example, when the remaining time is 4 minutes, the control unit 226 causes the display element D to blink red at a medium cycle, and when the remaining time is a negative value (that is, when the predicted time of component shortage has been exceeded), the control unit 226 causes the display element D to invert between red and green at a short cycle.

[0060] <Operational Effect> According to an embodiment of the present invention described above, various operational effects can be obtained. For example, according to an embodiment of the present invention, when component shortage-related information is received, the display element D starts to display (light up or blink), and the display pattern of the display element D changes over time. According to such a configuration, when a plurality of display elements D are lit up or blinking, an operator can determine the priority of in what order the component reels P should be replenished to the component mounting apparatus 10 based on the display patterns of the respective display elements D. As a result, it is possible to suppress the occurrence of a situation where the electronic components run out in the component mounting apparatus 10 and the operation of the component mounting apparatus 10 stops.

[0061] Also, when component shortage-related information is simply transmitted according to only the remaining number of electronic components, after the component shortage-related information is transmitted and before an actual component shortage occurs, it may be the case that the mounting of electronic components on all the previously prepared substrates is completed. In this case, it may not be necessary to replenish the component reel P to the component mounting apparatus 10. The operator can appropriately determine the necessity of such replenishment of the component reel P by checking the status of the substrates and the display patterns.

[0062] Also, the control unit 226 according to an embodiment of the present invention causes the display element D to display in a display pattern corresponding to the remaining time from the current time to the predicted time of component shortage. Therefore, the operator can grasp the remaining time until the predicted time of component shortage based on the display pattern of the display element D.

[0063] Further, when the component shortage-related information includes the predicted component shortage time, the control unit 226 can execute the above control based on the predicted component shortage time. When the component shortage-related information does not include the predicted component shortage time, the control unit 226 can execute the above control by calculating the time after a predetermined time from the reception of the component shortage-related information as the predicted component shortage time.

[0064] Further, based on detecting that the component reel P has been taken out from the component storage unit C having the display element D for which the display has been started, the control unit 226 ends the display of the display element D. With such a configuration, it becomes easier for the operator to proceed with the work without confusion.

[0065] <Modification Example> As described above, one embodiment of the present invention has been described. Hereinafter, some modification examples of the above-described embodiment will be described. Each of the modification examples described below may be applied to the above-described embodiment alone or in combination. Further, each modification example may be applied in place of the configuration of the above-described embodiment or may be additionally applied to the configuration of the above-described embodiment.

[0066] For example, although the case where the component storage unit C lights up or blinks in a display pattern according to the remaining time has been described above, when the component storage unit C has a function of displaying numbers, the control unit 226 may cause the component storage unit C to display a number indicating the remaining time. Further, when the component storage unit C has a function of displaying an indicator, the control unit 226 may cause the component storage unit C to display an indicator indicating a smaller amount as the remaining time decreases.

[0067] Also, in the above description, an example in which the display element D is arranged in each component storage section C has been described. However, a sound output device that outputs sound such as voice or buzzer sound may be arranged in each component storage section C. In this case, the control unit 226 causes the sound output device to output voice or buzzer sound or the like in a manner corresponding to the remaining time. Specifically, the control unit 226 may increase the volume of the buzzer sound output to the sound output device as the remaining time decreases. Further, the control unit 226 may cause the sound output device to output voice with content corresponding to the remaining time.

[0068] In addition to the display element D provided in each component storage section C, a second notification section not associated with an individual component storage section C may be provided in the storage shelf main body 210. In this case, the control unit 226 causes the second notification section to execute a notification based on the reception of component shortage-related information. The second notification section can execute a notification by means of display such as lighting or flashing, or output of sound. For example, the second notification section may be installed on the top panel 213. According to such a configuration, even when the operator is not near the storage shelf main body 210, it is easy for the operator to notice the reception of component shortage-related information based on the notification by the second notification section.

[0069] Furthermore, when identification information such as a number is attached to each component storage section C, the second notification section may display or output by voice the identification information of the component storage section C that stores the component reel P of the electronic component targeted by the component shortage-related information. In this case, the display element D may not be provided in each component storage section C.

[0070] Also, when the component storage sections C that store the component reels P of the same electronic component exist in a grouped range, the second notification section may display or output by voice information indicating the range in which the component storage section C that stores the component reel P of the electronic component targeted by the component shortage-related information exists. For example, when the component storage sections C that store the component reels P of the same electronic component exist on the same mounting shelf 212, the second notification section may display or output by voice information indicating the mounting shelf 212 on which the component storage section C that stores the component reel P of the electronic component targeted by the component shortage-related information exists.

[0071] In the above description, an example in which the reel storage shelf 20 has the component management device 220 has been described. However, the functions of the component management device 220 may be implemented in a management server on a network. In this case, the management server has functions such as a component management unit 223, a communication unit 224, a time management unit 225, and a control unit 226. The management server transmits an execution instruction and an end instruction of a notification to the storage shelf main body 210, and the storage shelf main body 210 executes the notification according to these instructions.

[0072] <Hardware Configuration> As described above, each embodiment of the present invention has been described. The information processing such as the calculation of the remaining time and the control of the notification described above is realized by the cooperation of software and hardware. Hereinafter, an example of a hardware configuration applicable to the reel storage shelf 20 will be described.

[0073] FIG. 8 is a block diagram showing an example of a hardware configuration 90. The hardware configuration 90 includes a CPU (Central Processing Unit) 901, a ROM (Read Only Memory) 902, a RAM (Random Access Memory) 903, and a host bus 904. The hardware configuration 90 also includes a bridge 905, an external bus 906, an interface 907, an input device 908, a display device 909, an audio output device 910, a storage device 911, a drive 912, and a network interface 915.

[0074] The CPU 901 functions as an arithmetic processing device and a control device, and controls the overall operation according to various programs. The CPU 901 may also be a microprocessor. The ROM 902 stores programs, arithmetic parameters, etc. used by the CPU 901. The RAM 903 temporarily stores programs used in the execution of the CPU 901 and parameters that change as appropriate during the execution. These are interconnected by a host bus 904 composed of a CPU bus or the like.
