Summary of the Invention

Problems to be Solved by the Invention

[0006] When introducing electronic storage units that can electronically manage parts reels, it is sometimes possible to replace all existing non-electronic storage units with electronic storage units at once, or to replace existing non-electronic storage units with electronic storage units in stages. In the latter case, there will be a period in which electronic and non-electronic storage units are used in combination. If workers use the two types of storage units in different ways during this period, there are concerns about work efficiency. Furthermore, the technology disclosed in Patent Document 1 assumes that all storage shelves used have IC tag readers. For this reason, it is difficult to apply the technology disclosed in Patent Document 1 during the period in which electronic and non-electronic storage units are used in combination.

[0007] Therefore, the present invention has been made in view of the above problems, and the object of the present invention is to provide a technology that can improve work efficiency in situations in which multiple types of storage units are used in combination. [Means for solving the problem]

[0013] The second storage unit has one or more code displays, the operator's operation is to read the code displays with a terminal, and the parts management device may further include a communication unit that receives the reading results of the code displays transmitted from the terminal.

[0014] The storage unit stores a plurality of storage rules, and the parts management device may further include a rule determination unit that determines which of the plurality of storage rules to use.

[0015] The plurality of storage rules may include a first storage rule indicating that the electronic component to be stored can be stored in any of the component storage sections of the plurality of storage units.

[Modes for carrying out the invention]

[0021] Embodiments of the present invention will be described in detail below with reference to the attached drawings. In this specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant descriptions will be omitted.

[0022] One embodiment of the present invention relates to a component management system for managing electronic components used in a product manufacturing line. Electronic components are mounted onto a substrate by a component mounting device also known as a chip mounter (surface mount machine). The component management system according to one embodiment of the present invention sets up multiple storage rules for electronic components and determines the storage rule to be used from among the multiple storage rules. First, an overview of the component management system according to one embodiment of the present invention will be described with reference to Figure 1.

[0023] <Overview of the parts management system> Figure 1 is an explanatory diagram showing a system according to one embodiment of the present invention. As shown in Figure 1, the system according to one embodiment of the present invention comprises a higher-level system 10, a parts management system 20, and a general storage unit 30. The parts management system 20 and the general storage unit 30 are located in a parts storage area (for example, a warehouse).

[0024] The higher-level system 10 and the parts management system 20 are connected to each other via a network 12. The network 12 is a wired or wireless transmission path for information transmitted from devices connected to the network 12. For example, the network 12 may include public networks such as the Internet, telephone networks, and satellite communication networks, as well as various LANs (Local Area Networks) and WANs (Wide Area Networks) including Ethernet®. The network 12 may also include dedicated network lines such as IP-VPN (Internet Protocol-Virtual Private Network).

[0025] (Higher-level system 10) The higher-level system 10 is a system that controls the operation of the component management system 20. The higher-level system 10 sends instructions to the component management system 20 and receives information from the component management system 20. A component mounting device for mounting electronic components onto a circuit board may be connected to either the higher-level system 10 or the component management system 20. The component mounting device has multiple feeders, each of which is fitted with a component reel containing different types of electronic components. The component mounting device mounts the electronic components contained on the component reels onto the circuit board via the feeders. Hereafter, electronic components may be simply referred to as components.

[0026] (Parts Management System 20) The parts management system 20 has the function of storing parts reels and the function of managing the stored parts reels. The external configuration example of the parts management system 20 will be described below with reference to Figure 2.

[0027] Figure 2 is an explanatory diagram showing an example of the external configuration of the parts management system 20. As shown in Figure 2, the parts management system 20 includes an electronic storage unit 210, also called a reel storage shelf, and a parts management device 220. The operator stores the parts reels in the electronic storage unit 210. Furthermore, if a parts shortage is likely to occur in the parts mounting device, or if a parts shortage has occurred, the operator replenishes the electronic parts by taking a parts reel from the electronic storage unit 210 and replacing the parts reel set in the parts mounting device with the reel in question.

[0028] The electronic storage unit 210 comprises a pair of side frames 211, a plurality of mounting shelves 212, a top panel 213, a plurality of casters 214, and a notification section 216.

[0029] A pair of side frames 211 extend perpendicularly to the mounting surface of the electronic storage unit 210. Multiple mounting shelves 212 are installed between the pair of side frames 211 at different height positions. A top panel 213 connects the upper ends of the pair of side frames 211. Casters 214 support the electronic storage unit 210 so that it can move.

[0030] Each mounting shelf 212 has multiple component storage compartments C. Each component storage compartment C houses a component reel P. The component reels P stored in each component storage compartment C can house different electronic components. Each component reel P is housed in a wound state, for example, with tape such as paper tape to which multiple electronic components are attached, or embossed tape formed by setting electronic components in multiple recesses.

[0031] Furthermore, each component storage section C is provided with a display element D. The display element D may be an LED (Light Emitting Diode) lamp that lights up or flashes in various colors. However, each component storage section C may be provided with a speaker that outputs sound or voice instead of, or in addition to, the display element D. Each component storage section C also has a sensor that detects whether or not a component reel has been stored in it. The electronic storage unit 210 is an example of a first storage unit that has the function of detecting the storage of component reels (electronic components) in each component storage section C.

[0032] The notification unit 216 is installed on top of the top panel 213. The notification unit 216 is the part that provides notifications to the worker through displays, lights, sounds, or voice.

[0033] The parts management device 220 stores information about the electronic components stored in the electronic storage unit 210. Furthermore, when an operator attempts to store a parts reel P in the electronic storage unit 210, the parts management device 220 controls the execution of guidance notifications that direct the operator to the parts storage section C where the parts reel P should be stored. The parts management device 220 will be described in detail later with reference to Figure 4.

[0034] (General storage unit 30) The general storage unit 30 is an example of a second storage unit having one or more component storage sections for storing component reels, and not having a function to detect the storage of component reels (electronic components) in the component storage sections. In Figure 1, multiple general storage units 30 are shown, but only one general storage unit 30 may be used.

[0035] Figure 3 is an explanatory diagram showing an example of the external configuration of a general storage unit 30. As shown in Figure 3, the general storage unit 30 has a plurality of mounting shelves 312. Each mounting shelf 312 has a plurality of parts storage sections F (F1, F2, etc.). Each parts storage section F can store one or more parts reels P. Each parts storage section F may be, for example, a box, or it may be a space separated by partitions on the mounting shelf 312.

[0036] Furthermore, the general storage unit 30 is assigned multiple two-dimensional codes 320. For example, the general storage unit 30 is assigned two-dimensional code 320A, and each mounting shelf 312 is assigned two-dimensional codes 320B to 320E. Two-dimensional code 320A indicates information that identifies the general storage unit 30, and two-dimensional codes 320B to 320E indicate information that identifies each mounting shelf 312. In addition, each parts storage section F is also assigned a two-dimensional code that indicates information that identifies each parts storage section F. Note that two-dimensional codes are just one example of code representation, and other code representations such as one-dimensional codes may be used as code representations.

[0037] In this specification, a general storage unit 30 having a plurality of mounting shelves 312 and a plurality of parts storage compartments F is shown as an example of a second storage unit, but a single parts storage compartment F (for example, a box-shaped parts storage compartment) may be used as the general storage unit 30.

[0038] <Configuration of parts management device 220> Figure 4 is an explanatory diagram mainly showing the configuration of a parts management device 220 according to one embodiment of the present invention. Figure 4 also shows each parts storage section Cj (j=1, 2, ...). Each parts storage section Cj is provided with a sensor Ej in addition to the display element Dj described above. The sensor Ej detects whether or not a parts reel P is stored in the parts storage section Cj, whether or not a parts reel P is stored in the parts storage section Cj, and whether or not a parts reel P has been removed from the parts storage section Cj. The sensor Ej may be, for example, a magnetic sensor.

[0039] As shown in Figure 4, the parts management device 220 includes an operation display unit 222, a storage unit 223, a communication unit 224, and a control unit 226.

[0040] (Operation display section 222) The operation display unit 222 has the function of an operation unit that accepts operations from the operator, and the function of a display unit that displays information. However, the operation unit function and the display unit function may be implemented separately. For example, the operation display unit 222 displays the application rule setting screen, the storage range specification screen for each picking list, the storage range adjustment screen, and the picking list selection screen. Details of each screen will be described later.

[0041] (Storage unit 223) The memory unit 223 stores various information and programs used for the operation of the parts management device 220. The memory unit 223 is composed of, for example, memory on the control unit 226's circuit board or an SSD (Solid State Drive). As shown in Figure 4, the memory unit 223 stores the OS (Operating System), storage reel information, operation panel application, storage rule settings, application rule settings, and managed unit information. The memory unit 223 also stores circuit board firmware, which is not shown.

[0042] The OS is software that implements input / output functions such as data input from the operation display unit 222 and screen output by the operation display unit 222, management of the storage unit 223, and a clock function that provides the date and time.

[0043] The storage reel information is information indicating the electronic components stored in each storage unit. For example, the storage reel information includes information indicating the electronic components stored in each component storage section C in the electronic storage unit 210. The storage reel information also includes information indicating the electronic components stored in the general storage unit 30, information indicating the electronic components stored in each mounting shelf 312 of the general storage unit 30, or information indicating the electronic components stored in each component storage section F.

[0044] For example, when storing a parts reel P in the electronic storage unit 210, after the barcode reader 230 reads the barcode attached to the parts reel P, the worker stores the parts reel P in the parts storage section C, and the sensor Ej detects which parts storage section Cj the parts reel P is stored in. Based on the detection result from the sensor Ej, the control unit 226 stores the parts information of the parts reel P that was previously read by the barcode reader 230 and the parts storage section Cj in which the parts reel P is stored as storage reel information in the storage unit 223. Note that the barcode reader 230 and the parts management device 220 may communicate via wired or wireless communication.

[0045] On the other hand, when storing a parts reel P in the general storage unit 30, the worker reads the two-dimensional code 320 attached to the general storage unit 30, the rack 312, or the parts storage section F in which they intend to store the parts reel using a terminal, and the terminal transmits information indicating the result of the reading to the parts management device 220. The control unit 226 stores the information received from the terminal and the parts information of the parts reel P previously read by the barcode reader 230 as storage reel information in the storage unit 223. The terminal may be the barcode reader 230 or another type of terminal. For example, if a worker places the parts reel P in a cart and moves it to store the parts reel P in the electronic storage unit 210 or the general storage unit 30, the terminal may be provided on the cart.

[0046] Figure 5 is an explanatory diagram illustrating a specific example of storage reel information. In the example shown in Figure 5, the storage reel information is associated with information indicating component storage section C or F, the item name of the component, and the quantity of the component. For example, the information indicating component storage section C1 is associated with the item name "Component N-1" and the quantity of the component "2000". This indicates that component reel P, which contains "2000" electronic components with the component management number "Component N-1", is stored in component storage section C1. Also, the information indicating component storage section C3 is associated with the item name and the quantity of the component "empty". This indicates that component reel P is not stored in component storage section C3, and component storage section C3 is empty. Furthermore, the information indicating component storage section F1 is associated with the item name "Component N-6" and the quantity of the component "1000". This indicates that a parts reel P containing 1,000 electronic components with part management number "part N-6" is stored in the parts storage section F1 of the general storage unit 30.

[0047] The control panel application is software that generates various operation screens to be displayed on the operation display unit 222. The control unit 226 generates various operation screens based on the functions of the control panel application and displays these various operation screens on the operation display unit 222.

[0048] The storage rule settings indicate how the parts reels P should be stored in the electronic storage unit 210 under each of the multiple storage rules. These storage rule settings can be configured based on the operator's actions on the operation screen displayed on the operation display unit 222. The multiple storage rules include, as an example of a first storage rule, free address; as an example of a second storage rule, per picking list, inventory mode, and semi-free address. Each storage rule will be described in detail later.

[0049] The application rule setting indicates which storage rule will be applied as the storage rule to be used. This application rule setting is configured by the operator through operations on the application rule setting screen displayed on the operation display unit 222 via the operation panel application.

[0050] Figure 6 is an explanatory diagram showing a specific example of the application rule setting screen 40. The worker selects the storage rule they want to apply by selecting the button 41-a corresponding to "free address", the button 41-b corresponding to "by picking list", the button 41-c corresponding to "inventory mode (ledger order)", or the button 41-d corresponding to "semi-free address". When the worker presses the OK button 49, the control unit 226 stores the storage rule set or changed by the worker as the application rule setting in the storage unit 223 and ends the display of the application rule setting screen 40. On the other hand, when the worker presses the cancel button 50, the control unit 226 does not change the application rule setting and ends the display of the application rule setting screen 40.

[0051] The managed unit information is information indicating the storage location of each parts reel in a semi-free address system. The managed unit information also includes information that general storage units 30, which do not have the function of electronically managing the inbound and outbound of parts reels P, are used as storage locations, and is stored in association with the storage reel information.

[0052] (Communications Department 224) The communication unit 224 communicates various information with the higher-level system 10. Furthermore, when a component mounting device is connected to the component management system 20, the communication unit 224 also communicates various information with the component mounting device.

[0053] (Control unit 226) The control unit 226 controls the overall operation of the parts management device 220. For example, the control unit 226 controls the display by the operation display unit 222, communication by the communication unit 224, and storage in the storage unit 223 based on the OS and operation panel application stored in the storage unit 223. In particular, in one embodiment of the present invention, the control unit 226 has the function of a rule determination unit that determines one of the multiple storage rules stored in the storage unit 223 as the storage rule to be used, and the function of a notification control unit that controls the execution of guidance notifications according to the storage rule to be used when storing electronic components to be stored. The control unit 226 also has the function of updating storage reel information related to the electronic storage unit 210 based on the storage of a parts reel P into the electronic storage unit 210 detected by the electronic storage unit 210, and updating storage reel information related to the general storage unit 30 based on the operator's operation (for example, reading a two-dimensional code) associated with the storage of a parts reel P into the general storage unit 30.

[0054] <Storage Rules> The configuration of the parts management device 220 according to one embodiment of the present invention has been described above. Next, the following will be explained for each of the multiple storage rules: "free address," "by picking list," "inventory mode (in ledger order)," and "semi-free address."

[0055] "Free address" is a rule in which a parts reel P may be stored in any of the parts storage sections of multiple storage units, including the electronic storage unit 210 and the general storage unit 30. "Per picking list" is a rule in which a range of storage locations is determined for each picking list, and parts reel P may be stored freely within the range associated with the picking list to which the parts reel P belongs. "Inventory mode (ledger order)" is a rule in which a range of storage locations is determined for each type of part listed in the ledger, and parts reel P may be stored freely within the range associated with the parts reel P. "Semi-free address" is a rule in which a range of storage locations among multiple storage units is associated and stored for each parts reel P, and parts reel P may be stored freely within the range associated with the parts reel P. Detailed explanations of "Per picking list," "Inventory mode (ledger order)," and "Semi-free address" follow below.

[0056] (Per picking list) Figure 7 is an explanatory diagram illustrating a specific example of a picking list. More specifically, Figure 7 shows two picking lists (Picking List A and Picking List B). Each picking list is a list of one or more types of electronic components used to create a certain circuit board. In a picking list, the required quantity may include the quantity of each electronic component needed to create a unit number (e.g., 100 pieces) of circuit boards.

[0057] If the picking list shown in Figure 7 has been created and the usage and storage rule is "per picking list", the storage state of the parts reel P in the electronic storage unit 210 will be, for example, the state shown in Figure 8.

[0058] Figure 8 is an explanatory diagram showing a specific example of the storage state of parts reels P in the electronic storage unit 210. In Figure 8, the item name and remaining quantity of the parts contained in each parts reel P are written above the respective parts reel P. As shown in Figure 8, the parts reels P for parts A-1 to A-5 included in picking list A are stored in the slot range 63 for picking list A. Within the slot range 63 for picking list A, parts reels P for parts A-1 to A-5 included in picking list A can be stored in any slot. Similarly, the parts reels P for parts B-1 to B-5 included in picking list B are stored in the slot range 64 for picking list B. Within the slot range 64 for picking list B, parts reels P for parts B-1 to B-5 included in picking list B can be stored in any slot.

[0059] Furthermore, parts reels P, such as parts C-1 and C-2, which are not included in any picking list, are placed in slot range 65 for parts not included in the picking list. In addition, there may be empty slot range 66 that is not assigned to any picking list or to parts not included in the picking list.

[0060] In addition, although the above describes a specific example of the storage state of the parts reel P in the electronic storage unit 210, the range of storage locations may be defined for each picking list in multiple storage units, including the electronic storage unit 210 and the general storage unit 30.

[0061] The control unit 226 may guide the worker by lighting up the display element D of an empty slot within the range that can accommodate the part reel P, if the storage location of the part reel P whose barcode has been read by the barcode reader 230 is the electronic storage unit 210, as a guidance notification. For example, if the barcode of the part reel P for part B-1 is read by the barcode reader 230, the control unit 226 may light up the display element Dx of an empty part storage section Cx within the slot range 64 for picking list B.

[0062] On the other hand, the control unit 226 may guide the operator by indicating that the parts reel P to be stored, whose barcode has been read by the barcode reader 230, should be stored in the general storage unit 30, or by displaying the storage location in the general storage unit 30 on the operation display unit 222.

[0063] (Inventory mode (in ledger order)) Figure 9 is an explanatory diagram showing a specific example of an account book. In the account book, as shown in Figure 9, the item names of multiple parts are listed in order.

[0064] If a ledger like the one shown in Figure 9 is created and the usage and storage rule is "inventory mode (ledger order)", the storage state of the parts reel P in the electronic storage unit 210 will be, for example, the state shown in Figure 10.

[0065] Figure 10 is an explanatory diagram showing a specific example of the storage state of component reels P in the electronic storage unit 210. As shown in Figure 10, each component reel P is housed within the range associated with that component reel P. For example, the component reel P for component A-1 is housed in the slot range 91 for component A-1, the component reel P for component A-2 is housed in the slot range 92 for component A-2, the component reel P for component A-3 is housed in the slot range 93 for component A-3, the component reel P for component A-4 is housed in the slot range 94 for component A-4, and the component reel P for component A-5 is housed in the slot range 95 for component A-5. Furthermore, the part reel P for part B-1 is housed in slot range 96 for part B-1, the part reel P for part B-2 is housed in slot range 97 for part B-2, the part reel P for part B-3 is housed in slot range 98 for part B-3, the part reel P for part B-4 is housed in slot range 99 for part B-4, and the part reel P for part B-5 is housed in slot range 100 for part B-5. In other words, adjacent slot ranges are associated with parts that are in a consecutive order in the ledger.

[0066] In addition, although a specific example of the storage state of the parts reel P in the electronic storage unit 210 was described above, in multiple storage units including the electronic storage unit 210 and the general storage unit 30, the range of adjacent storage locations may be associated with parts that are in a consecutive order in the ledger.

[0067] The control unit 226 may guide the worker by lighting up the display element D of an empty slot within the range in which the part reel P to be stored, when the electronic storage unit 210 is the storage location of the part reel P whose barcode has been read by the barcode reader 230, as a guidance notification. For example, when the barcode of the part reel P of part B-1 is read by the barcode reader 230, the control unit 226 may light up the display element Dy of an empty part storage section Cy within the slot range 96 for part B-1.

[0068] On the other hand, the control unit 226 may guide the operator by indicating that the parts reel P to be stored, whose barcode has been read by the barcode reader 230, should be stored in the general storage unit 30, or by displaying the storage location in the general storage unit 30 on the operation display unit 222.

[0069] (Semi-free address) Figure 11 is an explanatory diagram showing a specific example of managed unit information stored in the memory unit 223. Figure 12 is an explanatory diagram showing a specific example of component storage in a semi-free address system. As shown in Figure 11, in the managed unit information, each component is associated with a storage location. For example, components A-1 to A-3 and components B-1 to B-3 are associated with electronic storage unit A. That is, the storage location for components A-1 to A-3 and components B-1 to B-3 is electronic storage unit A, and as shown in Figure 12, the worker may store components A-1 to A-3 and components B-1 to B-3 in any location within electronic storage unit A.

[0070] Furthermore, in Figure 11, part Z-1 is associated with general storage unit B. In other words, the storage location for part Z-1 is general storage unit B, and the worker may store part Z-1 in any location within general storage unit B, as shown in Figure 12.

[0071] Furthermore, in Figure 11, parts Z-2 and Z-3 are associated with the general storage unit C. That is, the storage location for parts Z-2 and Z-3 is the general storage unit C, and the worker may store parts Z-2 and Z-3 in any location within the general storage unit C, as shown in Figure 12.

[0072] Furthermore, in Figure 11, part Z-4 is associated with the first tier of the general storage unit D. That is, the storage location for part Z-4 is the first tier of the general storage unit D, and the worker may store part Z-4 in any location on the first tier of the general storage unit D, as shown in Figure 12.

[0073] Furthermore, in Figure 11, part Z-5 is associated with general storage unit D_2nd tier_1. The number at the end indicates the number from the left when viewing the parts storage section F toward general storage unit 30. That is, the storage location for part Z-5 is the leftmost parts storage section F on the second tier of general storage unit D, and the worker stores part Z-5 in the leftmost parts storage section F on the second tier of general storage unit D, as shown in Figure 12. Similarly, parts Z-6 and Z-7 are stored in the second and third parts storage sections F from the left, respectively, on the second tier of general storage unit D.

[0074] In a "semi-free address" configuration, the control unit 226 may guide the worker by lighting up the display element D of an empty slot within the range where the parts reel P to be stored can be stored, as a guidance notification, if the storage location of the parts reel P to be stored, as read by the barcode reader 230, is the electronic storage unit 210. On the other hand, if the storage location of the parts reel P to be stored, as read by the barcode reader 230, is the general storage unit 30, the control unit 226 may guide the worker by indicating that the parts reel P should be stored in the general storage unit 30, or by displaying the storage location in the general storage unit 30 on the operation display unit 222.

[0075] (supplement) In "free address" mode, the control unit 226 does not need to provide any special guidance notification, or it may light up the display elements D of all available component storage units C as guidance notification, or it may light up one or more of the display elements D of the available component storage units C as guidance notification.

[0076] In "Picking List by List," "Inventory Mode (Ledger Order)," and "Semi-Free Address," it is possible that the picking list to which part reel P belongs, or the range associated with the parts contained in part reel P, is already filled, making it impossible to store part reel P in that range. In such cases, the control unit 226 may light up the display element D of an empty slot in a range not associated with any picking list or part as a guidance notification.

[0077] When the usage and storage rule is switched to "by picking list," "inventory mode (ledger order)," or "semi-free address," the worker may remove all parts reels P from each storage unit once and then re-store the parts reels P based on the guidance notification. Alternatively, the worker does not have to perform the above removal and re-storement. This is because, even without the above removal and re-storement, it is assumed that the storage state in each storage unit will gradually approach a state that conforms to the usage and storage rule as parts reels P are removed and new parts reels P are stored through normal use.

[0078] <Preparation> The storage rules have been explained above. Next, we will describe the preparatory steps for the operation of the parts management system 20 according to one embodiment of the present invention.

[0079] The operator sets multiple storage rules and other settings through various operation screens generated by the control unit 226 based on the functions of the operation panel application.

[0080] (Screen for specifying storage range for each picking list) First, we will explain an example screen for specifying the slot range associated with each picking list in the storage rule "per picking list".

[0081] Figure 13 is an explanatory diagram showing a specific example of the storage range specification screen for each picking list. On the storage range specification screen for each picking list, the worker selects the picking list for which they want to specify the storage range from the picking list selection list 71.

[0082] Furthermore, the operator specifies the orientation for the storage range in the orientation specification setting 72. The orientation specification setting 72 includes a schematic diagram of the electronic storage unit 210 and two arrows pointing towards the electronic storage unit 210. If the parts reel P can be stored on the right side (front) and the left side (back) of the electronic storage unit 210, the operator specifies either the front or back side in the orientation specification setting 72. Figure 13 shows an example where the front side is specified by selecting the arrow pointing to the front side.

[0083] Next, in section designation 73, the worker designates a section from the orientation specified in orientation designation setting 72 as the storage area for the picking list specified in picking list selection list 71. In the example shown in Figure 13, the upper, middle, and lower sections are each divided into three sections, and the worker can designate any of these sections. However, the number of sections and the number of sections per section are not limited to the example above.

[0084] When an operator specifies a rectangle to indicate a section, the control unit 226 indicates that a picking list with the same pattern has been applied by applying the middle fill pattern of the leftmost rectangle of the picking list specified in the picking list selection list 71 to the unit rectangle as well.

[0085] Furthermore, the operator can release or adjust each compartment. For example, if the operator selects any compartment and selects the release button 74 (release the selected range), the control unit 226 can return that compartment to the "(unset)" state. Also, if the operator selects any compartment and selects the adjust button 75, the control unit 226 generates a storage range adjustment screen 80 and displays the storage range adjustment screen 80 on the operation display unit 222.

[0086] Figure 14 is an explanatory diagram showing a specific example of the storage range adjustment screen 80. As shown in Figure 14, the storage range adjustment screen 80 includes an item specification field 87, a row specification field 81, a section specification field 82, a start slot specification field 83, an end slot specification field 88, an OK button 85, and a cancel button 86. The range of the picking list displayed in the item specification field 87 is specified as the section specified in the row specification field 81 and section specification field 82, from the slot specified in the start slot specification field 83 to the slot specified in the end slot specification field 88.

[0087] After the worker adjusts the input on the storage range adjustment screen 80, if they press the OK button 85, the adjustment results will be reflected on the storage range specification screen 70 for each picking list. If the worker presses the Cancel button 86, the adjustment results will not be reflected on the storage range specification screen 70 for each picking list.

[0088] Subsequently, when the operator presses the OK button 76 on the storage range specification screen 70 for each picking list, the control unit 226 stores the settings or adjustments made on the storage range specification screen 70 and the storage range adjustment screen 80 as storage rule settings for the storage rule "per picking list" in the storage unit 223, and terminates the display of the storage range specification screen 70. On the other hand, when the operator presses the Cancel button 77, the control unit 226 does not store the settings or adjustments made on the storage range specification screen 70 and the storage range adjustment screen 80 in the storage unit 223, and terminates the display of the storage range specification screen 70.

[0089] Although the above describes an example of specifying the storage range in the electronic storage unit 210, it is also possible to specify the storage range for each picking list in the general storage unit 30 in a similar manner. Furthermore, the storage range for the same picking list may span both the electronic storage unit 210 and the general storage unit 30.

[0090] (In inventory mode (in ledger order)) Similarly, in the "Inventory Mode (Ledger Order)" storage rule, it is possible to specify the storage location associated with each part using the storage range specification screen for each part type, which is generated by the control unit 226 based on the functions of the operation panel application. The storage range specification screen for each part type has almost the same screen configuration as the storage range specification screen 70 for each picking list, the only difference being that the list located in the upper left of the screen is a list of part types in the ledger. The other contents and operation methods are generally as explained in the storage range specification screen 70 for each picking list, so a detailed explanation is omitted here. In the storage range adjustment screen 80, the items listed in the item specification field 87 change from the type of picking list to the part type in the ledger. However, in the case of "Inventory Mode (Ledger Order)," adjustments that would cause the order of parts in the ledger and the order of the storage location ranges to not match are prohibited.

[0091] (In the case of a semi-free address system) Similarly, in the "semi-free address" storage rule, it is possible to specify the storage location associated with each part using the storage range specification screen for each part type, which is generated by the control unit 226 based on the functions of the operation panel application. The storage range specification screen for each part type has almost the same screen configuration as the storage range specification screen 70 for each picking list, the only difference being that the list located in the upper left of the screen is a list of part types. The other contents and operation methods are generally as described in the storage range specification screen 70 for each picking list, so a detailed explanation is omitted here.

[0092] <Operation> Next, the operation of the parts management system 20 according to one embodiment of the present invention will be described. The operation of the parts management system 20 described below will be performed after the above-mentioned preliminary preparations have been completed.

[0093] (Operation overview) First, with reference to Figure 15, an overview of the operation of the parts management system 20 according to one embodiment of the present invention will be described.

[0094] Figure 15 is a flowchart illustrating the operation overview of a parts management system 20 according to one embodiment of the present invention. As shown in Figure 15, first, the control unit 226 displays a storage screen on the operation display unit 222 based on the functions of the operation panel application (S1).

[0095] Next, the worker scans the barcode on the parts reel P with the barcode reader 230 (S2). Based on the functions of the operation panel application, the control unit 226 recognizes information about the item name and remaining quantity of parts on the parts reel P from the string read from the barcode.

[0096] Then, the control unit 226 reads the applicable rule settings from the storage unit 223 and sets the storage rule indicated by the applicable rule settings as the storage rule to be used (S3).

[0097] Subsequently, processing is performed according to the usage and storage rule (S4). For example, if the usage and storage rule is "free address" (S4 / free address), refer to Figure 16 and perform the processing described later (S5). Also, if the usage and storage rule is "per picking list" (S4 / per picking list), refer to Figures 17 and 18 and perform the processing described later (S6). Also, if the usage and storage rule is "inventory mode (ledger order)" (S4 / inventory mode (ledger order)), refer to Figure 20 and perform the processing described later (S7). Also, if the usage and storage rule is "semi-free address" (S4 / semi-free address), refer to Figure 21 and perform the processing described later (S8).

[0098] (Storage in a free-address system) Next, we will explain in more detail the storage arrangement in the free-address system shown in S5 of Figure 15.

[0099] Figure 16 is a flowchart showing storage in a free-address system. The worker selects whether or not to store the parts reel P in the electronic storage unit 210 (S200). If the worker selects to store the parts reel P in the electronic storage unit 210 (S200 / YES), they store the parts reel P in any available parts storage section C of the electronic storage unit 210 (S201). Then, the sensor E in the parts storage section C where the parts reel P is stored detects that the parts reel P has been stored (S202).

[0100] Next, the control unit 226 notifies the operator that the parts reel P has been successfully stored by lighting up the display element D of the parts storage section C where the parts reel P is stored in a success pattern, based on the functions of the operation panel application (S203). The notification to the operator may also be a buzzer sound or voice output indicating success.

[0101] Subsequently, the control unit 226 updates the storage reel information (S204) so ​​that the information regarding the item names and remaining quantities of parts of the parts reel P, which was acquired in S2 as shown in Figure 15, is associated with the parts storage unit C in which the parts reel P is stored.

[0102] On the other hand, if the worker chooses to store the parts reel P in the general storage unit 30 (S200 / NO), the worker reads the two-dimensional code 320 of any available storage location in one or more general storage units 30 (the two-dimensional code 320 attached to the general storage unit 30, the rack 312, or the parts storage section F) using a terminal (S205). The terminal transmits the result of reading the two-dimensional code 320 to the parts management device 220.

[0103] Subsequently, the worker stores the parts reel P in the storage location to which the scanned two-dimensional code 320 is attached (S206). Then, the control unit 226 of the parts management system 20 updates the storage reel information so that the information regarding the item name and remaining quantity of parts of the parts reel P, which was acquired in S2 as shown in Figure 15, is associated with the storage location indicated by the reading result of the two-dimensional code 320 (S207). After S204 or S207 described above, the storage operation for one parts reel P is completed.

[0104] In the above example, the two-dimensional code 320 is read before the worker stores the parts reel P in the general storage unit 30. However, the worker may also read the two-dimensional code 320 after storing the parts reel P in the general storage unit 30. Similarly, in the storage methods described below for each picking list, inventory mode, and semi-free address storage, the worker may also read the two-dimensional code 320 after storing the parts reel P in the general storage unit 30.

[0105] (Storage by picking list) Next, we will explain in more detail the storage for each picking list shown in S6 of Figure 15.

[0106] Figure 17 is a flowchart showing the storage process for each picking list. Figure 18 is a flowchart showing the process following Figure 17.

[0107] The control unit 226 checks all target picking lists to see whether the item of the part of the part reel P (the part reel P to be stored) acquired in S2 as shown in Figure 15 is included in the picking list (S301). If the item of the part of the part reel P to be stored is not included in any picking list (S301 / No), the control unit 226 applies the "not included in picking list" rule (S302).

[0108] On the other hand, if the item of the part of the part reel P to be stored is included in any picking list (S301 / Yes), the control unit 226 checks whether there is one picking list that includes the item of the part of the part reel P to be stored (S303). If there is one picking list that includes the item of the part of the part reel P to be stored (S303 / Yes), the control unit 226 applies the corresponding picking list (S304).

[0109] On the other hand, if there are two or more picking lists that include the items of parts on the parts reel P to be stored (S303 / No), the control unit 226 displays the picking list selection screen 51 on the operation display unit 222 (S305).

[0110] Figure 19 is an explanatory diagram showing a specific example of the picking list selection screen 51. As shown in Figure 19, the picking list selection screen 51 includes a selection list 52 that includes "Not included in picking list", "Picking list A", "Picking list B", etc. as selection items, and an OK button 53.

[0111] When an operator selects an item from the selection list 52 on the picking list selection screen 51 and presses the OK button 53 (S306), the control unit 226 applies the picking list corresponding to the selected item (S307). Subsequently, the control unit 226 obtains the range information of the applied picking list from the storage rule settings (S308).

[0112] Next, the control unit 226 determines whether the range indicated by the acquired range information is within the electronic storage unit 210, as shown in Figure 18 (S308-2). If the range indicated by the acquired range information is within the electronic storage unit 210 (S308-2 / YES), the control unit 226 identifies an empty component storage section C within the range indicated by the acquired range information by referring to the storage reel information, and lights up the display element D of the component storage section C as a guidance notification based on the function of the operation panel application (S309).

[0113] The operator places the parts reel P into the parts storage unit C in accordance with the illumination of the display element D (S310). When the sensor E detects that the parts reel P has been placed inside, information indicating the parts storage unit C where the sensor E is located is output to the control unit 226. Upon receiving this information, the control unit 226 turns off the display element D based on the function of the operation panel application.

[0114] Furthermore, the control unit 226 determines whether the parts storage unit C in which the parts reel P is stored is an available parts storage unit C within the range indicated by the picking list range information (S311). If the parts storage unit C in which the parts reel P is stored (target storage location) is an available parts storage unit C within the range indicated by the picking list range information (S311 / Yes), the control unit 226 notifies the worker that the parts reel P has been stored correctly by lighting up the display element D of the parts storage unit C in which the parts reel P is stored in a success pattern, based on the function of the operation panel application (S312). Subsequently, the control unit 226 updates the storage reel information so that the information regarding the item name and the remaining quantity of parts of the parts reel P, which was acquired in S2 as shown in Figure 15, is associated with the parts storage unit C in which the parts reel P is stored (S313).

[0115] On the other hand, if the parts storage unit C in which the parts reel P is stored is outside the range indicated by the range information (S311 / No), the control unit 226 notifies the operator of the error by lighting up the display element D of the parts storage unit C in which the parts reel P is stored in an error pattern, based on the function of the operation panel application (S314). The error notification may also be an output of a buzzer sound or voice indicating the error. Upon receiving notification of the occurrence of the error, the operator clears the error and restarts the process from the beginning (S315).

[0116] If the range information acquired in S308 indicates a range outside the electronic storage unit 210, that is, a range within the general storage unit 30 (S308-2 / NO), the control unit 226 performs an operation (S320) for storage in the general storage unit 30.

[0117] Specifically, the control unit 226 displays the range indicated by the range information acquired in S308 on the operation display unit 222 based on the functions of the operation panel application (S321). The worker reads the two-dimensional code 320 (the two-dimensional code 320 attached to the general storage unit 30, the mounting shelf 312, or the parts storage unit F) attached to the storage location where the parts reel P is to be stored (target storage location) using a terminal (S322). The terminal transmits the result of reading the two-dimensional code 320 to the parts management device 220.

[0118] The control unit 226 then determines whether the target storage location indicated by the reading result of the two-dimensional code 320 corresponds to the range indicated by the range information acquired in S308, that is, whether the target storage location conforms to the storage rules (S323). If the target storage location does not conform to the storage rules (S323 / NO), the control unit 226 performs control to notify that the target storage location is incorrect (S324). This notification may be, for example, a message displayed by the operation display unit 222, a message displayed by the notification unit 216, or the output of a buzzer sound or voice indicating an error. Then, the process from S322 is repeated.

[0119] If the target storage location conforms to the storage rules (S323 / YES), the control unit 226 performs control to notify that the target storage location is correct (S325). This notification may be, for example, a message displayed by the operation display unit 222, a message displayed by the notification unit 216, or the output of a buzzer sound or voice indicating that the target storage location is correct.

[0120] Subsequently, the worker places the parts reel P into the designated storage location to which the scanned two-dimensional code 320 is attached (S326). Then, the control unit 226 of the parts management system 20 updates the storage reel information so that the information regarding the item name and remaining quantity of parts of the parts reel P, which was acquired in S2 as shown in Figure 15, is associated with the designated storage location indicated by the scanning result of the two-dimensional code 320 (S327). After S313, S315, or S327 described above, the storage operation for one parts reel P is completed.

[0121] (Storage in inventory mode) Next, we will explain in more detail the storage method in inventory mode (in ledger order) shown in S7 of Figure 15.

[0122] Figure 20 is a flowchart showing the storage in inventory mode (in ledger order). First, the control unit 226 checks whether the item names of the parts on the parts reel P (parts reel P to be stored) acquired in S2 as shown in Figure 15 are included in the ledger (S401).

[0123] If the item name of the part to be stored on the parts reel P is not included in the ledger (S401 / No), the control unit 226 notifies the operator of the error by, for example, lighting up the notification unit 216 in an error pattern based on the function of the operation panel application (S408). The error notification may also be an output of a buzzer sound or voice indicating the error. Upon receiving notification of the occurrence of the error, the operator clears the error and restarts the process from the beginning (S409).

[0124] If the item names of the parts on the parts reel P to be stored are included in the ledger (S401 / YES), the control unit 226 obtains range information corresponding to the parts reel P to be stored from the storage rule settings (S402).

[0125] The control unit 226 determines whether the range indicated by the acquired range information is within the electronic storage unit 210 (S402-2). If the range indicated by the acquired range information is within the electronic storage unit 210 (S402-2 / YES), the control unit 226 identifies an empty component storage section C within the range indicated by the range information corresponding to the component reel P by referring to the storage reel information, and lights up the display element D of the component storage section C as a guidance notification based on the function of the operation panel application (S403).

[0126] The operator places the parts reel P into the parts storage unit C in accordance with the illumination of the display element D (S404). When the sensor E detects that the parts reel P has been placed inside, information indicating the parts storage unit C where the sensor E is located is output to the control unit 226. Upon receiving this information, the control unit 226 turns off the display element D based on the function of the operation panel application.

[0127] The control unit 226 then determines whether the parts storage unit C in which the parts reel P is stored is an available parts storage unit C within the range indicated by the range information corresponding to the parts reel P (S405). If the parts storage unit C in which the parts reel P is stored (target storage location) is an available parts storage unit C within the range indicated by the range information corresponding to the parts reel P (S405 / YES), the control unit 226 notifies the operator that the parts reel P has been stored correctly by lighting up the display element D of the parts storage unit C in which the parts reel P is stored in a success pattern, based on the function of the operation panel application (S406). Subsequently, the control unit 226 updates the storage reel information so that the information regarding the item name and the remaining number of parts of the parts reel P, which was acquired in S2 as shown in Figure 15, is associated with the parts storage unit C in which the parts reel P is stored (S407).

[0128] On the other hand, if the component storage unit C in which the component reel P is stored is outside the range indicated by the range information corresponding to the component reel P (S405 / NO), the process from S408 is performed.

[0129] If the range information acquired in S402 indicates a range outside the electronic storage unit 210, i.e., within the general storage unit 30 (S402-2 / NO), the control unit 226 performs an operation (S320) for storage in the general storage unit 30. The operation (S320) for storage in the general storage unit 30 is as described with reference to Figure 18.

[0130] (Storage in a semi-free-address system) Next, we will explain in more detail the storage arrangement in the semi-free address configuration shown in S8 of Figure 15.

[0131] Figure 21 is a flowchart showing storage in a semi-free address configuration. First, the control unit 226 checks whether the parts of the parts reel P (parts reel P to be stored) acquired in S2 as shown in Figure 15 are subject to management, that is, whether they are included in the managed unit information (S501). If the parts of the parts reel P to be stored are included in the managed unit information (S501 / YES), processing from S502 onwards is performed. If the parts of the parts reel P to be stored are not included in the managed unit information (S501 / NO), this operation ends.

[0132] If the components of the component reel P to be stored are included in the managed unit information (S501 / YES), the control unit 226 determines whether the storage location of the component reel P is the electronic storage unit 210 (502).

[0133] If the storage location for the component reel P is the electronic storage unit 210 (S502), the component reel P is stored in any available component storage section C of the electronic storage unit 210 (S201). Here, the control unit 226 may explicitly inform the operator that the storage location for the component reel P is the electronic storage unit 210 by displaying it on the operation display unit 222 or by notifying the operator from the notification unit 216. Alternatively, the control unit 226 does not need to control the notification indicating that the storage location for the component reel P is the electronic storage unit 210, in which case the operator can understand that the storage location for the component reel P is the electronic storage unit 210 simply because there was no special notification.

[0134] When the worker places the parts reel P into the parts storage unit C, the sensor E in the parts storage unit C where the parts reel P is stored detects that the parts reel P has been stored (S202).

[0135] Next, the control unit 226 notifies the operator that the parts reel P has been successfully stored by lighting up the display element D of the parts storage section C where the parts reel P is stored in a success pattern, based on the functions of the operation panel application (S203). The notification to the operator may also be a buzzer sound or voice output indicating success.

[0136] Subsequently, the control unit 226 updates the storage reel information (S204) so ​​that the information regarding the item names and remaining quantities of parts of the parts reel P, which was acquired in S2 as shown in Figure 15, is associated with the parts storage unit C in which the parts reel P is stored.

[0137] If the storage location for the component reel P to be stored is the general storage unit 30 (S502 / NO), the control unit 226 performs an operation (S320) for storage in the general storage unit 30. The operation (S320) for storage in the general storage unit 30 is as described with reference to Figure 18.

[0138] <Effects and Effects> According to the embodiment of the present invention described above, various effects and advantages can be obtained. For example, according to the embodiment of the present invention, when the electronic storage unit 210 and the general storage unit 30 are used in combination, parts management in the general storage unit 30 is also realized by the parts management system 20. Therefore, since workers can store parts reels P in the electronic storage unit 210 and parts reels P in the general storage unit 30 in a similar manner and with a similar feel, it is possible to improve work efficiency.

[0139] Furthermore, according to one embodiment of the present invention, the control unit 226 updates the storage reel information when the target storage location, which is the storage location of the parts reel P to be stored, conforms to the storage rules. In particular, when storing the parts reel P in the general storage unit 30, the target storage location is identified based on operations by an operator, such as reading the two-dimensional code 320. By such specific means, it is possible to realize parts management in the general storage unit 30.

[0140] Furthermore, the control unit 226 performs control to notify the worker of the storage location in accordance with the storage rules. With this configuration, the worker can understand where the parts reel P to be stored should be stored.

[0141] Furthermore, the control unit 226 performs control to notify the worker that the storage location is correct if it determines that the storage location conforms to the storage rules. On the other hand, the control unit 226 performs control to notify the worker that the storage location is incorrect if it determines that the storage location does not conform to the storage rules. With this configuration, the worker can understand whether their work is correct or incorrect and, if necessary, change the storage location of the parts reel P to a storage location that conforms to the storage rules.

[0142] Furthermore, according to one embodiment of the present invention, one of the multiple storage rules is determined as the storage rule to be used. With this configuration, it is possible to switch the storage rule to be used according to the purpose and needs.

[0143] Furthermore, the multiple storage rules include the "free address" storage rule. Under the "free address" storage rule, workers can store the parts reel P in any location among multiple storage units, including the electronic storage unit 210 and the general storage unit 30.

[0144] Furthermore, the multiple storage rules include the storage rules "by picking list," "inventory mode (book order)," and "semi-free address," in which the range of the parts storage section among multiple storage units is associated for each of one or more parts. In the storage rule "by picking list," parts reels P belonging to the same picking list are stored in a grouped area. Therefore, in the storage rule "by picking list," the amount of movement workers have to make when picking parts reels P is reduced, and as a result, picking efficiency may be improved. In the storage rule "inventory mode (book order)," each parts reel P is stored in the order recorded in the ledger. Therefore, in the storage rule "inventory mode (book order)," the amount of movement workers have to make when taking inventory is reduced, and as a result, inventory efficiency may be improved. The storage rule "semi-free address" has the effect of preventing a situation where parts reels P of the same part type are scattered throughout the warehouse while maintaining the flexibility of "free address."

[0145] For example, by setting the storage rule "Free Address" as the normal usage and storage rule, and the storage rule "Inventory Mode (Ledger Order)" as the usage and storage rule during inventory periods, it is possible to improve both the efficiency of normal storage and the efficiency of inventory work.

[0146] <Hardware Configuration> An embodiment of the present invention has been described above. The information processing, such as parts management and notification control described above, is realized through the cooperation of software and hardware. Below, an example of a hardware configuration that may be applied to the parts management device 220 will be described.

[0147] Figure 22 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 (HDD) 911, a drive 912, and a network interface 915.

[0148] The CPU 901 functions as both an arithmetic processing unit and a control unit, controlling the overall operation according to various programs. The CPU 901 may also be a microprocessor. The ROM 902 stores programs and arithmetic parameters used by the CPU 901. The RAM 903 temporarily stores programs used in the execution of the CPU 901 and parameters that change as needed during its execution. These are interconnected by a host bus 904, which consists of a CPU bus and other components. The functions of the control unit 226 can be realized through the cooperation of the CPU 901, ROM 902, RAM 903, and software.

[0149] The host bus 904 is connected to an external bus 906, such as a PCI (Peripheral Component Interconnect / Interface) bus, via a bridge 905. It is not always necessary to configure the host bus 904, bridge 905, and external bus 906 separately; these functions may be implemented on a single bus.

[0150] The input device 908 consists of input means for the user to input information, such as a mouse, keyboard, touch panel, buttons, microphone, sensor, switch, and lever, and an input control circuit that generates input signals based on the user's input and outputs them to the CPU 901. By operating the input device 908, the user can input various types of data and instruct processing operations.

[0151] The display device 909 includes, for example, a liquid crystal display (LCD) device, a projector device, an OLED (Organic Light Emitting Diode) device, and a lamp. The audio output device 910 includes an audio output device such as a speaker and headphones.

[0152] The storage device 911 is a data storage device configured as an example of a storage unit according to this embodiment. The storage device 911 may include a storage medium, a recording device for recording data on the storage medium, a reading device for reading data from the storage medium, and a deletion device for deleting data recorded on the storage medium. The storage device 911 is composed of, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive), or a memory having equivalent functionality. This storage device 911 drives the storage and stores programs executed by the CPU 901 and various data.

[0153] Drive 912 is a reader / writer for storage media and is either built into or external to the hardware configuration 90. Drive 912 reads information recorded on removable storage media 84, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, and outputs it to RAM 903 or storage device 911. Drive 912 can also write information to the removable storage media 84.

[0154] The network interface 915 is a communication interface composed of, for example, a communication device for connecting to the network 12. Furthermore, the network interface 915 may be a wireless LAN (Local Area Network) compatible communication device or a wired communication device for wired communication.

[0155] <Supplement> Although preferred embodiments of the present invention have been described in detail above with reference to the attached drawings, the present invention is not limited to these examples. It is clear to any person with ordinary skill in the art to which the present invention belongs that various modifications or alterations can be conceived within the scope of the technical idea described in the claims, and these are also understood to fall within the technical scope of the present invention.

[0156] For example, although four storage rules were explained above, more storage rules may be used, or three or fewer storage rules may be used.

[0157] Furthermore, although the above describes an example in which a two-dimensional code 320 is attached to the general storage unit 30, an IC tag may also be provided on the general storage unit 30, and the worker may read information identifying the general storage unit 30, information identifying each shelf 312, or information identifying each parts storage section F from the IC tag using contactless communication with a terminal. In addition, the general storage unit 30 displays information identifying the general storage unit 30, information identifying each shelf 312, or information identifying each parts storage section F, and the worker may select the information of the target storage location on the terminal, or manually enter the information of the target storage location into the terminal.

[0158] Furthermore, although the above describes an example in which one electronic storage unit 210 is used, multiple electronic storage units 210 may also be used. In this case, each electronic storage unit 210 communicates with the parts management device 220 to notify the parts management device 220 of the storage of parts lists in each parts storage unit C, etc.

[0159] Furthermore, the general storage unit 30 can also be used to store component reels P having a diameter or width that is not supported by the component storage section C of the electronic storage unit 210.

[0160] Furthermore, in cases where parts are supplied by business partners, it is possible to implement a usage model in which the scope of management, including the general storage unit 30, by the parts management device 220 is created for each business partner.

[0161] Furthermore, each step in the processing of the parts management system 20 described herein does not necessarily have to be processed chronologically in the order described in the flowchart. For example, each step in the processing of the parts management system 20 may be processed in an order different from the order described in the flowchart, or may be processed in parallel.

[0162] Furthermore, it is possible to create computer programs that enable the hardware, such as the CPU, ROM, and RAM, built into the parts management device 220 to perform functions equivalent to those of each component of the parts management device 220 described above. A non-temporary storage medium in which such computer programs are stored is also provided.

[0163] Furthermore, the functions of the operation display unit 222, storage unit 223, communication unit 224, and control unit 226 described above may be implemented within a single enclosure or distributed across multiple enclosures. If the above functions are implemented within a single enclosure, the device having that enclosure may correspond to the parts management device 220. If the above functions are distributed across multiple enclosures, one or more combinations of the multiple devices having each enclosure may correspond to the parts management device 220. In addition, if the above functions are distributed across multiple enclosures, an interface for inputting and outputting information between the devices having each enclosure is also implemented.

[0164] Furthermore, the concept encompassing the aforementioned embodiment of the present invention can be expressed, for example, as follows: A. A storage unit that stores storage reel information indicating the electronic components stored in each of a plurality of storage units, including a first storage unit having multiple component storage compartments and a function for detecting the storage of electronic components in each component storage compartment, and a second storage unit having one or more component storage compartments and not having a function for detecting the storage of electronic components in the component storage compartments. B. A control unit that updates the storage reel information for the first storage unit based on the storage of the electronic components into the first storage unit detected by the first storage unit, and updates the storage reel information for the second storage unit based on the operator's operation when the electronic components are stored into the second storage unit, Equipped with, Parts management device.

[0165] Regarding A above, the function for detecting the storage of electronic components may also be a function for detecting the storage of an object containing multiple electronic components (for example, a component reel). Alternatively, the function for detecting the storage of electronic components may also be a function for detecting that any object has been stored. This function may or may not include a function for detecting the type of electronic component or the number of electronic components. Furthermore, one component storage section may be capable of storing only one object, or it may be capable of storing multiple objects.

[0166] Regarding B above, the matters specified by "(expression indicating action 1) + based on + (verb indicating action 2)" include the fact that action 2 is performed after action 1 has been performed. The matters specified by "(expression indicating action 1) + based on + (verb indicating action 2)" are not limited to the fact that action 2 is performed automatically when the condition that action 1 has been performed is met, but may also include the fact that action 2 is performed when action 1 has been performed and other conditions have been met. Furthermore, such other conditions may include the fact that a predetermined human operation has been performed. For example, the matters specified by "update the storage reel information relating to the first storage unit based on the storage of the electronic component" in B above include both the fact that the storage reel information is updated automatically when the electronic component is stored, and the fact that the storage reel information is updated when the electronic component is stored and other conditions have been met. Similarly, the phrase "update the storage reel information relating to the second storage unit based on the operator's operation associated with the storage of the electronic components" in B above includes both cases: the storage reel information is automatically updated as a result of the operator's operation, and the storage reel information is updated as a result of the operator's operation and other conditions being met.

[0167] With respect to B above, "operations by the worker in connection with the storage of the electronic components" may be operations that the worker is required to perform before or after storing the electronic components, according to rules, manuals, or customs.

[0168] With respect to B above, the matters specified by "updating storage reel information" may include adding information to the storage reel information, rewriting some or all of the information in the storage reel information, and deleting some or all of the information from the storage reel information.
