Description

Parts supply system, storage device and parts supply device

[0001] The technology disclosed in this specification relates to a technology for storing component supply devices that supply components to component mounters.

[0002] Patent Document 1 discloses a component mounting line including a component mounter, a feeder that supplies components to the component mounter, and a storage facility that temporarily stores the feeder. The storage facility has a connector for connecting to the feeder. When the feeder is connected to the storage facility's connector, the storage facility supplies power to the feeder. This enables communication between the storage facility and the feeder, and the storage facility obtains identification information from the feeder.

[0003] International Publication No. 2020 / 165972

[0004] The storage cabinet of Patent Document 1 continuously supplies power to the feeder while the connector of the storage cabinet and the feeder are connected. Therefore, power may continue to be supplied to the feeder even after the storage cabinet acquires identification information from the feeder. This specification provides a technology that can reduce the power supplied from the storage cabinet to the component supply device compared to conventional technology.

[0005] The component supply system disclosed in this specification includes a component supply device that supplies components to a component mounting machine that mounts the components on a board; a storage device that is configured to be able to store the component supply device; a storage detection unit that detects that the component supply device has been stored in the storage device; a power supply unit that supplies power to the component supply device in response to the storage detection unit detecting that the component supply device has been stored in the storage device; and a stopping unit that stops the power supply unit from supplying power to the component supply device when a predetermined condition is met after the power supply unit has supplied power to the component supply device.

[0006] In the component supply system described above, when a predetermined condition is met after the power supply unit starts supplying power to the component supply device, the power supply unit stops supplying power to the component supply device. Therefore, even if the component supply device is stored in the storage device, power is not continuously supplied to the component supply device after the predetermined condition is met. This allows the power supplied to the component supply device to be reduced.

[0007] This specification also discloses a storage device for a component supplying device that supplies components to a component mounter that mounts the components on a board. The storage device includes a storage unit configured to store the component supplying device, a storage detection unit that detects that the component supplying device has been stored in the storage unit, a power supply unit that supplies power to the component supplying device in response to the storage detection unit detecting that the component supplying device has been stored in the storage unit, and a stop unit that stops the power supply from the power supply unit to the component supplying device when a predetermined condition is met after the power supply unit has supplied power to the component supplying device.

[0008] Furthermore, this specification also discloses a component supplying device that supplies components to a component mounter that mounts the components on a board, the component supplying device including: a storage detection unit that detects that the component supplying device has been stored in a storage device; and a stop request unit that requests the storage device to stop supplying power when a predetermined condition is satisfied after the storage detection unit detects the storage in the storage device and power is supplied from the storage device to the component supplying device.

[0010] The main features of the embodiments described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0011] (Feature 1) In the above-described component supply system, the storage device may include a connection unit for connecting to the component supply device. In this case, the storage detection unit may detect that the component supply device is stored in the storage device by detecting connection of the component supply device to the connection unit, and the power supply unit may supply power to the component supply device via the connection unit.

[0012] According to this configuration, both the detection of the storage of the component supply device in the storage device and the supply of power from the storage device to the component supply device are performed via the connection part of the storage device. Therefore, compared to a configuration that includes a separate sensor for detecting the storage of the component supply device in the storage device, the storage of the component supply device in the storage device can be detected with a simpler configuration.

[0013] (Feature 2) The storage device may further include an acquisition unit configured to acquire information about the component supply device from the component supply device via the connection by the connection unit. In this case, acquisition of information by the acquisition unit may be executable when power is being supplied from the power supply unit to the component supply device, and the predetermined condition may be satisfied when the acquisition unit completes acquisition of the information.

[0014] According to this configuration, the storage device can acquire information about the component supply device by supplying power to the component supply device, and after the information is acquired, the supply of power to the component supply device is stopped. Therefore, it is possible to prevent power from being continuously supplied to the component supply device after the information is acquired, and it is possible to reduce the power supplied to the component supply device.

[0015] (Feature 3) The above-mentioned storage device may further include a memory that stores the information acquired by the acquisition unit, a removal detection unit that detects that the component supply device stored in the storage unit has been removed, and a deletion unit that deletes the information in the memory when the removal detection unit detects that the component supply device has been disconnected.

[0016] According to this configuration, after the component supply device is removed from the storage device, the information about the removed component supply device is deleted from the memory, which reduces the memory capacity compared to a configuration in which the information about the removed component supply device is continuously stored in the memory after removal.

[0017] (Feature 4) In the storage device described above, the storage unit may be configured to include a plurality of storage locations, and to be able to store the component supply device in each of the plurality of storage locations. In this case, the storage detection unit may detect that the component supply device has been stored in each of the plurality of storage locations, the power supply unit may supply power to the component supply device stored in each of the plurality of storage locations, the acquisition unit may acquire information about the component supply device stored in each of the plurality of storage locations, and the memory may store the information about the component supply device acquired by the acquisition unit in association with identification information that identifies the storage location where the component supply device is stored.

[0018] With this configuration, even if multiple component supply devices are stored in the storage unit, information about each of the multiple component supply devices can be stored in association with identification information that specifies the storage location where the component supply device is stored. This allows for more appropriate management of information about the component supply devices than a configuration in which information about the component supply devices is stored without being associated with identification information about the storage location.

[0019] In the storage device described above, the removal detection unit may detect, for each storage location, that the component supply device stored in the storage device has been removed. In this case, when the removal detection unit detects that the component supply device has been removed, the deletion unit may delete information about the removed component supply device.

[0020] With this configuration, for example, when one of the multiple component supply devices is removed, only the information about the removed component supply device is deleted, thereby making it possible to appropriately manage the information about the component supply devices currently stored in the storage device.

[0021] (Feature 6) The storage device may further include a transmission unit that transmits information about the component supply device in the memory and the identification information associated with the component supply device to an external management device.

[0022] According to this configuration, by transmitting information about the component supply device and identification information that specifies its storage location to the management device, the management device can appropriately manage this information.

[0023] (Feature 7) In the storage device described above, the information about the component supply device may include device identification information for identifying the component supply device.

[0024] According to this configuration, the storage device can identify the component supply device stored therein by acquiring the device identification information.

[0025] (Feature 8) In the storage device described above, the predetermined condition may be satisfied when a predetermined time has elapsed since the storage detection unit detected that the component supply device has been stored in the storage unit.

[0026] According to this configuration, the supply of power to the component supply device is stopped after the predetermined time has elapsed, so that the power supplied to the component supply device can be reliably reduced.

[0027] 1 shows a front view of a component supply system 100 according to a first embodiment. The component supply system 100 includes component mounters 10F and 10S, a storage device 20, a loader 40, and a management device 80. The component mounters 10F and 10S are connected to each other to form a component mounting line. In this embodiment, the component supply system 100 includes a component mounting line made up of two component mounters 10F and 10S. However, in a modified example, the component supply system 100 may include only one component mounter, or may include a component mounting line made up of three or more component mounters.

[0028] Each of the mounters 10F and 10S mounts components 4 on a board 2 and is also referred to as an electronic component mounting device or a chip mounter. The mounter 10F includes a feeder holder 12F and a touch screen 14F. The feeder holder 12F is equipped with feeders F1, F2, and F3. The feeders F1, F2, and F3 are component supply devices that supply components 4 to the mounter 10F, and in this embodiment, are tape feeders. Although not shown, the mounter 10F moves the components 4 supplied from the feeders F1, F2, and F3 onto the board 2 using a mounting head and a head moving device, and mounts the components on the board 2. The touch screen 14F is a display device that provides various information about the mounter 10F to the operator and an input device that accepts instructions and information from the operator. The mounter 10F then transports the board 2, on which the components 4 have been mounted, to the mounter 10S.

[0029] The component mounter 10S has a similar configuration to the component mounter 10F and includes a feeder holder 12S and a touch screen 14S. The feeder holder 12S of the component mounter 10S holds feeders F4, F5, and F6. The component mounter 10S receives the board 2 carried out by the component mounter 10F and mounts the components 4 supplied from the feeders F4, F5, and F6 onto the board 2. In this manner, in the component supply system 100 of this embodiment, when the component mounters 10F and 10S are viewed from the front, the component mounter 10F located on the left transports the board 2 toward the component mounter 10S located on the right. Hereinafter, the +X direction (i.e., the right direction in FIG. 1 ) may be simply referred to as "right," and the -X direction may be simply referred to as "left." In addition, the +Z direction (i.e., the upward direction on the paper in FIG. 1) may be simply referred to as "up," the -Z direction may be simply referred to as "down," the +Y direction (i.e., the direction into the paper in FIG. 1) may be simply referred to as "rear," and the -Y direction (i.e., the direction towards the paper in FIG. 1) may be simply referred to as "front."

[0030] The loader 40 is a device that automatically attaches and detaches feeders to and from the feeder holding units 12F, 12S of the mounters 10F, 10S. As shown by the arrow in FIG. 1 , the loader 40 can move left and right between the storage device 20 and the mounters 10F, 10S while holding multiple feeders F7, F8. Based on instructions from the management device 80, for example, the loader 40 removes feeders F7, F8 stored in the storage device 20 from the storage device 20 and moves, for example, to the front of the mounter 10F while holding the feeders F7, F8. The loader 40 supplies feeder F7 to the feeder holding unit 12F of the mounter 10F, then moves to the front of the mounter 10S and detaches feeder F8 to the feeder holding unit 12S of the mounter 10S. Furthermore, the loader 40, for example, removes the feeder F1 placed in the feeder holding section 12F of the component mounting machine 10F from the feeder holding section 12F, moves to the front of the storage device 20 while holding the feeder F1, and stores the feeder F1 in the storage device 20.

[0031] Storage device 20 is located at the leftmost position of component supply system 100. Storage device 20 stores feeders before they supply components 4 to board 2 and feeders after they have supplied components 4 to board 2. In a modified example, storage device 20 may store only one of the feeders before or after they have supplied components 4. Storage device 20 may also store only one feeder.

[0032] The storage device 20 includes four lower slots 21A-21D, four upper slots 22A-22D, a control unit 30, a bottom plate 24, a pair of side plates 26, and a power cable 28. Each slot 21A-21D, 22A-22D stores a feeder. The lower slots 21A-21D are arranged in a row from left to right, and the upper slots 22A-22D are arranged in a row from left to right. In this embodiment, for example, as shown in FIG. 1 , the lower slot 21B stores feeder F10, and the lower slot 21C stores feeder F11. Similarly, the upper slots 22A-22D store feeders F12-F15, respectively. The lower slots 21A and 21D do not store feeders. The control unit 30 is disposed on the bottom plate 24. The bottom plate 24 is a flat plate member extending in the left-right direction and connects the lower ends of the pair of side plates 26. The pair of side plates 26 are flat plate members extending in the up-down direction and hold the left-right ends of each of the slots 21A to 21D, 22A to 22D. Casters 26C are arranged on the lower ends of the pair of side plates 26. The control unit 30 is connected to the management device 80 so as to be able to communicate with them. The power cable 28 is connected to an external power source (not shown). The power cable 28 is capable of supplying power from the external power source to the storage device 20.

[0033] The management device 80 is located at a location away from the component mounters 10F, 10S and the storage device 20, and is a computer that manages the operation of each of the devices 10F, 10S, 20, and 40 of the component supply system 100. The management device 80 may be connected to each of the devices 10F, 10S, 20, and 40 of the component supply system 100 by wire or wirelessly. In a modified example, the management device 80 may be located adjacent to the storage device 20, for example.

[0034] The detailed structure of the storage device 20 will be described with reference to Figure 2. Figure 2 is a cross-sectional view taken along line II-II in Figure 1, and mainly shows the structure of the lower slot 21A and the upper slot 22A. The lower slot 21A and the upper slot 22A have the same configuration. The other lower slots 21B to 21D and the upper slots 22B to 22D also have the same configuration as the lower slot 21A and the upper slot 22A.

[0035] The lower slot 21A includes a slot body 23A and a connecting portion 50A. The slot body 23A is a plate-like member with an L-shaped cross section, extending in the left-right direction (i.e., toward the front and rear of the paper in FIG. 2). The slot body 23A includes a bottom plate extending in the front-rear direction and a back plate extending from the rear end of the bottom plate perpendicular to the bottom plate. The bottom plate is inclined so that it is displaced downward toward the rear. The connecting portion 50A is located on the back plate.

[0036] The connection portion 50A includes a current-carrying portion 52A, a movable portion 54A, and a hinge portion 56A. The current-carrying portion 52A and the movable portion 54A are made of a conductive material (e.g., iron). The current-carrying portion 52A is electrically connected to an external power source via a power cable 28 (see FIG. 1). A coil spring (not shown) provided in the hinge portion 56A biases the movable portion 54A so that the lower end of the movable portion 54A moves away from the back plate. As shown in FIG. 1, no feeder is stored in the lower slot 21A. Therefore, the movable portion 54A in the lower slot 21A does not abut against the current-carrying portion 52A.

[0037] Like the lower slot 21A, the upper slot 22A also includes a slot body 25A and a connecting portion 60A. As shown in FIG. 2 , a feeder F12 is stored in the upper slot 22A. Because the bottom plate of the slot body 25A is tilted downward toward the rear, the feeder F12 pushes the movable portion 64A of the connecting portion 60A rearward. As a result, the coil spring provided in the hinge portion 66A elastically deforms, causing the lower end of the movable portion 64A to pivot rearward and abut against the current-carrying portion 62A. If the feeder F12 were to be removed from the upper slot 22A, the restoring force of the coil spring provided in the hinge portion 66A would cause the lower end of the movable portion 64A to separate from the current-carrying portion 62A.

[0038] The feeder F12 includes a reel 70 and a connection terminal 76. The reel 70 includes a reel body 72 and a tape 74 wound around the outer periphery of the reel body 72. The tape 74 accommodates a plurality of components 4. The connection terminal 76 is exposed on the rear end surface of the feeder F12. The connection terminal 76 is made of a conductive material (e.g., iron) and electrically connects the internal equipment of the feeder F12 to the outside. When the feeder F12 is stored in the storage device 20, the connection terminal 76 abuts against the movable part 64A. As a result, the connection terminal 76 is connected to an external power source via the movable part 64A and the conductive part 62A. This allows the storage device 20 to supply power to the feeder F12 via the connection part 60A.

[0039] The control configuration of the component supply system 100 will be described with reference to Figure 3. The storage device 20 includes a control unit 30, connection units 50A-50D and 60A-60D for the multiple slots 21A-21D and 22A-22D, and a communication I / F (abbreviation for interface) 29. The communication I / F 29 is, for example, an I / F for communicating with the management device 80. The connection units 50A-50D and 60A-60D also include voltage sensors 58A-58D and 68A-68D, respectively. Each voltage sensor 58A-58D and 68A-68D is a sensor that detects a loopback voltage, which will be described later, and is, for example, a photocoupler.

[0040] The control unit 30 of the storage device 20 includes a CPU 32 and a memory 34. The memory 34 is configured from volatile memory, non-volatile memory, etc. The memory 34 stores a program 36 and a storage ID table T1. The CPU 32 executes various processes in accordance with the program 36 stored in the memory 34. The control unit 30 is communicatively connected to the communication I / F 29 and each of the connection units 50A to 50D and 60A to 60D.

[0041] As shown in FIG. 3, storage ID table T1 is a table for managing information about feeders stored in storage device 20. Storage ID table T1 stores connection IDs that identify each of connection sections 50A-50D and 60A-60D and feeder IDs that identify the feeders, in association with each other. For example, connection section 50A of lower slot 21A is assigned connection ID 5A, and connection section 60A of upper slot 22A is assigned connection ID 6A. Similarly, connection sections 50B-50D are assigned connection IDs 5B-5D, respectively, and connection sections 60B-60D are assigned connection IDs 6B-6D, respectively.

[0042] As described with reference to FIG. 2 , for example, connection 60A of upper slot 22A is connected to feeder F12. Therefore, in storage ID table T1, connection ID 6A of connection 60A is stored in association with feeder ID 112 of feeder F12. Similarly, connection IDs 5B and 5C are stored in association with feeder ID 110 of feeder F10 and feeder ID 111 of feeder F11, respectively. Connection IDs 6B to 6D are stored in association with feeder IDs 113 to 115, respectively. In this way, by storing storage ID table T1 in memory 34, storage device 20 can appropriately manage the feeder IDs of the feeders stored therein.

[0043] The management device 80 includes a display unit 81, an operation unit 82, a communication I / F 83, and a control unit 84. The display unit 81 is a display that displays various information related to the component supply system 100. The operation unit 82 is an interface that accepts various inputs from the administrator. The control unit 84 is communicatively connected to the display unit 81, the operation unit 82, and the communication I / F 83. The control unit 84 includes a CPU 85 and a memory 86. The memory 86 is configured with volatile memory, non-volatile memory, etc. The memory 86 stores a program 87 and an ID table. The CPU 85 executes various processes in accordance with the program 87 stored in the memory 86. The details will be described with reference to FIG. 4 , but the ID table is a table for storing feeder IDs received from the storage device 20. The CPU 85, for example, displays the ID table in the memory 86 on the display unit 81 in accordance with the program 87. This allows the administrator to know the feeders stored in the storage device 20. Furthermore, the CPU 85 controls the operation of the loader 40 and the component mounters 10F, 10S based on a production program including the types and order of components 4 to be mounted on the board 2 by the component mounters 10F, 10S, for example, in accordance with the program 87. For example, the CPU 85 controls the loader 40 based on the feeder ID shown in the ID table, and moves the feeders stored in the storage device 20 to the component mounters 10F, 10S.

[0044] Each of the feeders F1 to F15 has the same configuration. Therefore, the following mainly describes the control configuration of the feeder F12 shown in FIG. 2. In addition to the connection terminal 76, the feeder F12 also includes a control unit 90 and a loopback wiring 78. The control unit 90 is communicatively connected to the connection terminal 76. The loopback wiring 78 electrically connects one terminal located on the rear end surface of the feeder F12 to the other terminal located on the rear end surface of the feeder F12. The loopback wiring 78 electrically connects both terminals located on the rear end surface of the feeder F12 without being connected to internal devices of the feeder F12, such as the control unit 90. The control unit 90 includes a CPU 92 and a memory 94. The memory 94 is configured from a volatile memory, a non-volatile memory, etc. The memory 94 stores a program 96 and a feeder ID. For example, in the feeder ID management process shown in FIG. 4, the CPU 92 transmits the feeder ID in the memory 94 to the storage device 20 in accordance with the program 96 .

[0045] Here, a method by which the control unit 30 (i.e., the CPU 32) of the storage device 20 detects the storage of a feeder in the storage device 20 and the removal of a feeder from the storage device 20 will be described. For example, as shown in FIG. 2 , when feeder F12 is stored in the upper slot 22A of the storage device 20, two terminals of the loopback wiring 78 of feeder F12 are connected to the connection part 60A via the movable part 64A and the conductive part 62A. As a result, a loopback voltage is generated in the connection part 60A via the loopback wiring 78 of feeder F12. The generation of the loopback voltage is detected by a voltage sensor 68A of the connection part 60A. When the voltage sensor 68A detects the generation of the loopback voltage, the CPU 32 can detect that feeder F12 has been stored in the upper slot 22A. In this way, the CPU 32 detects that a feeder has been stored in each slot by detecting the generation of a loopback voltage from the voltage sensors 58A to 58D, 68A to 68D of the respective connection sections 50A to 50D, 60A to 60D.

[0046] As described above, the loopback wiring 78 electrically connects both terminals without connecting to the internal devices of the feeder F12. Therefore, a loopback voltage is generated even if the feeder F12 is not activated. This makes it possible to detect that the feeder F12 is stored in the storage device 20 without supplying power to the feeder F12.

[0047] The CPU 32 of the storage device 20 detects the storage of feeders in slots 21A to 21D and 22A to 22D by detecting the occurrence of loopback voltages in the connections 50A to 50D and 60A to 60D. As described above, the storage device 20 supplies power to the feeders via the connections 50A to 50D and 60A to 60D. Therefore, it is possible to detect the storage of feeders in slots 21A to 21D and 22A to 22D with a simpler configuration than a configuration in which the storage of feeders in slots 21A to 21D and 22A to 22D is detected using a sensor (e.g., an infrared sensor) separate from the connections 50A to 50D and 60A to 60D that supply power to the feeders.

[0048] Furthermore, for example, when the voltage sensor 68A of the connection unit 60A detects the disappearance of the loopback voltage, the CPU 32 detects that the feeder F12 has been removed from the upper slot 22A. That is, when the connection between the connection units 50A-50D, 60A-60D and each of the feeders F1-F15 is released, the CPU 32 of the storage device 20 detects the removal of the feeder from the feeder slots 21A-21D, 22A-22D. In this way, the CPU 32 detects the removal of a feeder for each slot by the voltage sensors 58A-58D, 68A-68D of each of the connection units 50A-50D, 60A-60D detecting the disappearance of the loopback voltage. In a modified example, the connection units 50A to 50D and 60A to 60D may detect the storage and removal of feeders using proximity sensors instead of the voltage sensors 58A to 58D and 68A to 68D detecting the generation and disappearance of loopback voltage.

[0049] 4, a description will be given of the feeder ID management process executed by the CPU 32 of the control unit 30 of the storage device 20. The process in FIG. 4 is executed in response to the power switch (not shown) of the storage device 20 being turned on after the power cable 28 of the storage device 20 is connected to an external power source.

[0050] The CPU 32 monitors whether any of the voltage sensors in the connection sections 50A to 50D, 60A to 60D detects the occurrence of a loopback voltage (S10). That is, in S10, the CPU 32 monitors whether a feeder is stored in a slot of the storage device 20. If no loopback voltage is generated in any of the connection sections (NO in S10), the CPU 32 determines that no feeder is stored in the slot of the storage device 20, and proceeds to S30.

[0051] If the voltage sensor detects the occurrence of loopback voltage (YES in S10), that is, if the storage of the feeder electrically connects the loopback wiring to the connection part, the CPU 32 identifies the connection part that has the voltage sensor that detected the occurrence of loopback voltage (S12). Hereinafter, the feeder stored in the storage device 20 will be referred to as the "target feeder," and the connection part identified in S12 will be referred to as the "storage connection part."

[0052] The CPU 32 supplies power to the target feeder via the storage connection by turning on a supply switch (not shown) electrically connected between the storage connection and the power source (S14), which starts up the control unit 90 of the target feeder.

[0053] The CPU 32 transmits an ID request to the target feeder via the storage connection unit (S16). The ID request is information for requesting the target feeder to transmit a feeder ID.

[0054] The CPU 32 monitors whether a feeder ID is received from the target feeder (S20). If the CPU 32 does not receive a feeder ID from the target feeder (NO in S20), the process returns to S16. The CPU 32 repeats sending an ID request until it receives a feeder ID from the target feeder.

[0055] When the CPU 32 receives the feeder ID from the target feeder (YES in S20), it associates the received feeder ID with the connection part ID of the storage connection part identified in S12 and stores them in the storage ID table T1 (S22). By storing the feeder ID that identifies the target feeder in the storage ID table T1, it is possible to identify the target feeder stored in the storage device 20 and its storage location.

[0056] Furthermore, the CPU 32 transmits the feeder ID of the target feeder stored in S22 and the connection part ID of the storage connection part to the management device 80 (S24). As a result, the management device 80 stores the received feeder ID and connection part ID in an ID table in association with each other, and can appropriately manage each ID.

[0057] Next, the CPU 32 stops the supply of power to the target feeder by turning off the supply switch (S26), which stops the activation of the control unit 90 of the target feeder.

[0058] Next, the CPU 32 monitors whether any of the voltage sensors of the connection units 50A to 50D, 60A to 60D detects the disappearance of the loopback voltage (S30). That is, the CPU 32 monitors whether the target feeder is transported out of the slot of the storage device 20 (S30). If none of the voltage sensors detects the disappearance of the loopback voltage (NO in S30), the process returns to S10 again.

[0059] When the voltage sensor detects the disappearance of the loopback voltage (YES in S30), that is, when the electrical connection between the loopback wiring of the feeder and the connection is released, the CPU 32 identifies the connection having the voltage sensor that detected the disappearance of the loopback voltage (S32). Hereinafter, the connection identified in S32 will be referred to as the "export connection."

[0060] When any feeder stored in the storage device 20 is transported out of the storage device 20, the CPU 32 deletes the feeder ID stored in association with the connection ID of the output connection from the storage ID table T1 (S34). This allows the capacity of the memory 34 to be reduced compared to a configuration in which the feeder ID of the transported feeder is continuously stored. Also, the feeder IDs of feeders that are stored without being transported out can be appropriately managed. In a modified example, in S34, the CPU 32 may delete the connection ID of the output connection from the storage ID table T1 in addition to the feeder ID stored in association with the connection ID of the output connection.

[0061] Furthermore, the CPU 32 sends a deletion request including the feeder ID deleted in S34 to the management device 80 (S36). As a result, the management device 80 deletes the feeder ID included in the deletion request from the feeder IDs stored in the ID table. This allows the management device 80 to update the storage status in the storage device 20.

[0062] (Effects of this embodiment) In the component supply system 100 of this embodiment, after the CPU 32 of the storage device 20 supplies power to the target feeder (S14), when it receives a feeder ID from the target feeder (YES in S20), it stops the supply of power to the target feeder (S26). Therefore, after receiving the feeder ID from the target feeder, power is not supplied to the target feeder. This makes it possible to reduce the power supplied to the target feeder compared to conventional technology in which power is continuously supplied to the target feeder while the target feeder is connected to the storage connection unit. Furthermore, because power is continuously supplied to the target feeder until the feeder ID is received from the target feeder, it is possible to reliably receive the feeder ID from the target feeder.

[0063] The correspondence in this embodiment is as follows: Feeder F1 to F15 are an example of a "component supply device." Lower slots 21A to 21D and upper slots 22A to 22D are an example of a "storage location." The feeder ID is an example of "device identification information," and the connection part ID is an example of "identification information that specifies a storage location."

[0064] The process of S10 is an example of a process executed by a "storage detection unit". The process of S14 is an example of a process executed by a "power supply unit". The process of S26 is an example of a process executed by a "stop unit". The process of S20 is an example of a process executed by an "acquisition unit". The process of S30 is an example of a process executed by a "removal detection unit". The process of S34 is an example of a process executed by a "deletion unit". The process of S24 is an example of a process executed by a "sending unit".

[0065] Second Embodiment A component supply system 100 according to a second embodiment will be described with reference to Fig. 5. The component supply system 100 according to this embodiment executes a feeder ID management process different from that of the first embodiment, but otherwise has the same configuration as that of the first embodiment.

[0066] In the feeder ID management process of this embodiment, after sending an ID request to the target feeder (S16), if the CPU 32 of the storage device 20 does not receive a feeder ID (NO in S20), it monitors whether a predetermined time has elapsed since detecting the connection between the target feeder and the storage connection unit in S10 (S120). The predetermined time is the time during which it is determined that the feeder ID will be received reliably if no abnormalities have occurred in the target feeder or the storage connection unit, and is pre-stored in the memory 34. Note that the predetermined time can be changed later by an operator or administrator. If the predetermined time has not elapsed (NO in S120), the CPU 32 returns to S16, sends an ID request to the target feeder, and monitors for the reception of the feeder ID (S20). The ID request is sent to the target feeder until the predetermined time has elapsed. Furthermore, if the predetermined time has elapsed (YES in S120), the CPU 32 stops the supply of power to the target feeder regardless of whether the feeder ID is received (S26). If the feeder ID is not received after a predetermined time has elapsed, it is possible that some error has occurred in the feeder. Therefore, the CPU 32 outputs a message to that effect to the management device 80. This allows the worker to take action such as repairing the feeder.

[0067] According to the component supply system 100 of this embodiment, when a predetermined time has elapsed (YES in S120), the supply of power to the target feeder is stopped (S26). Therefore, it is possible to more reliably reduce the power supplied to the target feeder than, for example, a configuration in which the supply of power continues until a feeder ID is received from the target feeder even after the predetermined time has elapsed.

[0068] (Third Example) A component supply system 100 of a third example will be described with reference to Figure 6. In the component supply system 100 of this example, instead of the feeder ID management process executed by the CPU 32 of the storage device 20, the feeder ID transmission process shown in Figure 6 is executed by the CPU 92 of the target feeder. The CPU 92 of the target feeder starts the process of Figure 6 when the target feeder is connected to the storage connection unit and power is supplied to the target feeder. In other words, the process of Figure 6 is started when the target feeder is stored in the storage device 20.

[0069] The CPU 92 monitors whether an ID request is received from the storage device 20 (S210). This ID request is the same as the ID request sent to the target feeder in S16 of Fig. 4. The CPU 92 repeats the process of S210 until an ID request is received.

[0070] When the CPU 92 receives an ID request (YES in S210), it transmits the feeder ID of the target feeder stored in the memory 94 to the storage device 20 (S212). This allows the storage device 20 to obtain the feeder ID of the target feeder.

[0071] The CPU 92 monitors whether an ID reception signal is received from the storage device 20 (S220). The ID reception signal indicates that the feeder ID has been received by the storage device 20. If the CPU 92 does not receive an ID reception signal (NO in S220), the process returns to S212 and the CPU 92 again transmits the feeder ID to the storage device 20.

[0072] When the CPU 92 receives an ID reception signal from the storage device 20 (YES in S220), it transmits a supply stop request to the storage device 20 (S222). The supply stop request is information requesting the storage device 20 to stop supplying power. Upon receiving the supply stop request, the storage device 20 turns off the supply switch described above. This stops the supply of power to the target feeder. When the processing of S222 ends, the CPU 92 ends the processing of FIG. 6.

[0073] In the component supply system 100 of this embodiment, after power is supplied to the target feeder (triggering the process of FIG. 6 ), the CPU 92 transmits the feeder ID to the storage device 20 (S212), and then transmits a supply stop request to the storage device 20 (S222). This stops the supply of power to the target feeder. Therefore, after the target feeder transmits its feeder ID to the storage device 20, power is not supplied to the target feeder. This makes it possible to reduce the power supplied to the target feeder compared to conventional technology in which power is continuously supplied to the target feeder while the target feeder is connected to the storage connection unit. In this embodiment, connecting the connection terminal 76 of the target feeder to the storage connection unit is an example of a process executed by a "storage detection unit." Furthermore, the process of S222 is an example of a process executed by a "stop request unit."

[0074] A few points to note regarding the component supply system 100 described in the embodiment are described below. Feeder F1 to F15 may be compatible with wireless charging. In that case, for example, storage device 20 may not be equipped with connection units 50A to 50D, 60A to 60D. In this modification, the CPU 32 of storage device 20 may determine YES in S10, for example, when wireless communication (e.g., Bluetooth (registered trademark) communication or NFC (Near Field Communication) communication) with the target feeder is established. In that case, storage device 20 may supply power to the target feeder wirelessly in S14.

[0075] The storage device 20 does not have to be located at the leftmost position of the component supply system 100. For example, the storage device 20 may be located at the rightmost position of the component supply system 100. In another modification, the storage device 20 may be located between the component mounter 10F and the component mounter 10S.

[0076] The storage device 20 does not have to be located in the component supply system 100. For example, the storage device 20 may be located outside the component mounting line to temporarily store feeders. In another modified example, the storage device 20 may be located in a warehouse that stores multiple feeders for a long period of time.

[0077] The storage device 20 may, for example, only have the upper slots 22A to 22D and not have the lower slots 21A to 21D. In other words, the storage device 20 may have only one slot.

[0078] The CPU 32 of the storage device 20 may detect the storage of the target feeder in the storage device 20 by, for example, an infrared sensor instead of detecting the generation of loopback voltage by a voltage sensor in S10 of Fig. 4. In a further variation, the CPU 32 may detect the storage of the target feeder in the storage device 20 by a mass sensor that detects the mass of the target feeder in S10.

[0079] The CPU 32 may not execute the processes of S16 to S24 in Fig. 5. In this modification, after power is supplied to the target feeder in S14, the supply of power may be stopped when a predetermined time has elapsed, regardless of whether the feeder ID has been received or not.

[0080] The CPU 32 may send a pitch information request to the target feeder instead of sending an ID request to the target feeder in S16 of FIG. 4 . In this case, the target feeder may send, for example, pitch information indicating the pitch of the components 4 stored on the tape 74 to the storage device 20. In this modified example, the pitch information is an example of "information about the component supply device." Furthermore, in another modified example, instead of the ID request, a maintenance information request may be sent to the target feeder requesting information about maintenance of the target feeder, or a motor information request may be sent requesting information about the rotation speed of the motor that rotates the reel 70 of the target feeder. In these modified examples, the maintenance information and the information about the rotation speed of the motor are examples of "information about the component supply device."

[0081] The CPU 32 may not execute the process of S30 in Fig. 4. In that case, the CPU 32 may store the feeder ID of the target feeder in the storage ID table T1 along with the feeder ID history of feeders that were previously connected to the storage connection unit. In this modified example, the "discharge detection unit" and the "deletion unit" can be omitted.

[0082] The CPU 32 does not have to execute the process of S24 in FIG. 4. In this modification, the "transmission unit" can be omitted. In that case, for example, the CPU 32 may display the feeder ID and the connection unit ID stored in the storage ID table T1 on the display unit of the storage device 20. This allows the worker to identify the feeder currently stored in the storage device 20 by checking the display unit of the storage device 20.

[0083] The technical elements described in this specification or drawings exhibit technical utility either alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technologies illustrated in this specification or drawings simultaneously achieve multiple objectives, and achieving one of those objectives is itself technically useful.

Similarly, the technical idea of ​​changing "the storage device according to claim 4" to "the storage device according to any one of claims 4 to 9" in claim 10, and the technical idea of ​​changing "the storage device according to claim 3" to "the storage device according to any one of claims 3 to 10" in claim 11 are also disclosed.
