　（本開示に至る経緯）
　本開示に至る経緯について、図１を参照しながら説明する。 (Background to this disclosure)
The process leading to this disclosure will be described with reference to FIG.
　図１は、比較例のＲＦタグ読取システム１０１を示すブロック構成図である。 FIG. 1 is a block configuration diagram showing an RF tag reading system 101 of a comparative example.
　比較例のＲＦタグ読取システム１０１は、ＲＦタグＴｇの情報を取得するためのリーダライターモジュール１５１と、リーダライターモジュール１５１に接続された複数のアンテナＡ１００を有する読取装置１０４と、を備えている。例えば、このＲＦタグ読取システム１０１を部品供給装置に組み込むことで、アンテナＡ１００を介してバルクケースなどの収容体１０に付されたＲＦタグＴｇを読み取り、収容体１０に収容された部品の情報を取得することができる。図１に示すＲＦタグ読取システム１０１では、リーダライターモジュール１５１に１６個のポートが設けられ、１６個のポートに一対一で対応して１６個のアンテナＡ１００が接続されている。このＲＦタグ読取システム１０１によれば、１６個のアンテナＡ１００を介して１６個の収容体１０に収容された部品に関する情報を取得することができる。 The RF tag reading system 101 of the comparative example includes a reader / writer module 151 for acquiring information on the RF tag Tg, and a reading device 104 having a plurality of antennas A100 connected to the reader / writer module 151. For example, by incorporating this RF tag reading system 101 into a component supply device, the RF tag Tg attached to the housing body 10 such as a bulk case is read via the antenna A100, and information on the parts housed in the housing body 10 is read. Can be obtained. In the RF tag reading system 101 shown in FIG. 1, 16 ports are provided in the reader / writer module 151, and 16 antennas A100 are connected to the 16 ports in a one-to-one correspondence. According to the RF tag reading system 101, it is possible to acquire information about the parts housed in the 16 containment bodies 10 via the 16 antennas A100.
　しかしながら、多種類の部品が実装される実装装置では、例えば、１００を超える種類の部品が取り扱われることがある。一般にリーダライターモジュールに設けられるポートの数は限られており、上記リーダライターモジュール１５１のポートの数を増やすことは困難である。そのため、比較例のＲＦタグ読取システム１０１を備えた部品供給装置では、実装装置に供給する部品を管理することが困難である。 However, in a mounting device on which many types of parts are mounted, for example, more than 100 types of parts may be handled. Generally, the number of ports provided in the reader / writer module is limited, and it is difficult to increase the number of ports in the reader / writer module 151. Therefore, it is difficult to manage the parts supplied to the mounting device in the parts supply device provided with the RF tag reading system 101 of the comparative example.
　それに対し、本実施の形態に係る部品供給システムは、実装装置に供給する部品を管理することができる構成を有している。 On the other hand, the parts supply system according to the present embodiment has a configuration capable of managing the parts to be supplied to the mounting device.
　以下、実施の形態等について、図面を参照しながら説明する。以下で説明する実施の形態等は、いずれも包括的または具体的な例を示すものである。以下の実施の形態等で示される数値、形状、材料、構成要素、構成要素の配置位置および接続形態、ステップ、ステップの順序などは、一例であり、本開示を限定する主旨ではない。また、以下の実施の形態等における構成要素のうち、独立請求項に記載されていない構成要素については、任意の構成要素として説明される。 Hereinafter, embodiments and the like will be described with reference to the drawings.

Numerical values, shapes, materials, components, arrangement positions and connection forms of components, steps, order of steps, etc. shown in the following embodiments are examples, and are not intended to limit the present disclosure.

　（実施の形態）
　[１．部品供給システムおよび読取装置の構成]
　まず、実施の形態に係る部品供給システム、および、部品供給システムに含まれる読取装置の構成について説明する。 (Embodiment)
[1. Configuration of parts supply system and reader]
First, the configuration of the parts supply system according to the embodiment and the reading device included in the parts supply system will be described.
　図２は、実施の形態に係る部品供給システム１および読取装置４を示すブロック構成図である。 FIG. 2 is a block configuration diagram showing a component supply system 1 and a reading device 4 according to an embodiment.
　実施の形態に係る部品供給システム１は、部品供給システム１の稼働を制御する制御装置５と、制御装置５に通信接続された複数の読取装置４と、を備えている。なお、図２には、部品供給システム１が備える部品供給装置２も示されている。また、図２には、フィーダ２０、収容体１０、ならびに、フィーダ２０および収容体１０に付されたＲＦタグＴｇも示されている。ＲＦタグＴｇには、部品供給システム１で供給する部品に関する情報が含まれている。 The parts supply system 1 according to the embodiment includes a control device 5 that controls the operation of the parts supply system 1 and a plurality of reading devices 4 that are communication-connected to the control device 5. Note that FIG. 2 also shows a component supply device 2 included in the component supply system 1. FIG. 2 also shows the feeder 20, the containment body 10, and the RF tag Tg attached to the feeder 20 and the containment body 10. The RF tag Tg contains information about the parts supplied by the parts supply system 1.
　各読取装置４は、基板４０と、基板４０に設けられたスイッチング回路４３と、基板４０に形成された複数のアンテナＡＴと、を備えている。読取装置４は、制御装置５に含まれるリーダライターモジュール５１に通信接続されている。以下において、リーダライターモジュール５１をＲＷモジュール５１と呼ぶ場合がある。 Each reading device 4 includes a substrate 40, a switching circuit 43 provided on the substrate 40, and a plurality of antenna ATs formed on the substrate 40. The reading device 4 is communicatively connected to the reader / writer module 51 included in the control device 5. In the following, the reader / writer module 51 may be referred to as a RW module 51.
　図２に示すように、ＲＷモジュール５１は、信号の出入口である複数のポートを有している。１つのポートには１つのスイッチング回路４３が接続されている。すなわち、複数のポートには、複数のスイッチング回路４３が一対一の関係で接続されている。各スイッチング回路４３には、複数のアンテナＡＴが接続されている。図２には、制御装置５が１つのＲＷモジュール５１を有し、ＲＷモジュール５１が１６個のポートを有している例が示されている。また、１６個のポートには、１６個のスイッチング回路４３が一対一の対応で接続されている。１６個のスイッチング回路４３のそれぞれには、８個のアンテナＡＴが接続されている。このように、部品供給システム１は、１つのＲＷモジュール５１から１６個のスイッチング回路４３を介して、１２８個のアンテナＡＴに接続可能となっている。１２８個のアンテナを用いることで、読取装置４の周辺に位置する１２８個のＲＦタグＴｇを読み取ることができる。 As shown in FIG. 2, the RW module 51 has a plurality of ports that are entrances and exits of signals. One switching circuit 43 is connected to one port. That is, a plurality of switching circuits 43 are connected to the plurality of ports in a one-to-one relationship. A plurality of antenna ATs are connected to each switching circuit 43. FIG. 2 shows an example in which the control device 5 has one RW module 51 and the RW module 51 has 16 ports. Further, 16 switching circuits 43 are connected to the 16 ports in a one-to-one correspondence. Eight antenna ATs are connected to each of the 16 switching circuits 43. In this way, the component supply system 1 can be connected to 128 antenna ATs from one RW module 51 via 16 switching circuits 43. By using 128 antennas, 128 RF tags Tg located around the reader 4 can be read.
　以下、部品供給システム１が備える各構成要素について説明する。 Hereinafter, each component included in the parts supply system 1 will be described.
　前述したように制御装置５は、ＲＷモジュール５１を備えている。ＲＷモジュール５１は、ＲＦタグＴｇに記憶されている情報を読み出し、また、ＲＦタグＴｇに書込むべき情報を書き込むモジュールである。 As described above, the control device 5 includes the RW module 51. The RW module 51 is a module that reads out the information stored in the RF tag Tg and writes the information to be written in the RF tag Tg.
　ＲＷモジュール５１は、電波制御部５２および電源部５３を有している。なお、電源部５３は、ＲＷモジュール５１の外部であって、制御装置５の内部に設けられていてもよい。 The RW module 51 has a radio wave control unit 52 and a power supply unit 53. The power supply unit 53 may be provided outside the RW module 51 and inside the control device 5.
　電波制御部５２は、アンテナＡＴから放射する電波を制御する制御信号を出力する。この電波を制御する制御信号は、例えば、９２０ＭＨｚのＲＦＩＤ変調波を有する信号である。また、電波制御部５２は、電波を放射するアンテナＡＴを切り替えるため、スイッチング回路４３のオンオフを制御する制御信号も出力する。 The radio wave control unit 52 outputs a control signal for controlling the radio wave radiated from the antenna AT. The control signal for controlling this radio wave is, for example, a signal having an RFID modulated wave of 920 MHz. Further, the radio wave control unit 52 also outputs a control signal for controlling the on / off of the switching circuit 43 in order to switch the antenna AT that radiates the radio wave.
　電源部５３は、複数のアンテナＡＴが形成された基板４０に直流電流を供給する。この直流電流は、能動素子であるスイッチング回路４３を駆動するために用いられる電流である。これらの制御信号および直流電流は、重畳された多重信号としてＲＷモジュール５１から出力される。 The power supply unit 53 supplies a direct current to the substrate 40 on which a plurality of antenna ATs are formed. This direct current is a current used to drive the switching circuit 43, which is an active element. These control signals and DC currents are output from the RW module 51 as superimposed multiplex signals.
　部品供給システム１は、さらに、制御装置５と複数の読取装置４とを接続する複数の伝送路Ｌ１を備えている。各伝送路Ｌ１は、上記の多重信号を読取装置４の基板４０に伝送する。具体的には、伝送路Ｌ１は、電波制御部５２から出力された制御信号の伝送、および、電源部５３から出力された直流電流の給送を行う。 The component supply system 1 further includes a plurality of transmission lines L1 for connecting the control device 5 and the plurality of reading devices 4. Each transmission line L1 transmits the above-mentioned multiplex signal to the substrate 40 of the reader 4. Specifically, the transmission line L1 transmits a control signal output from the radio wave control unit 52 and supplies a direct current output from the power supply unit 53.
　伝送路Ｌ１となる配線としては、同軸ケーブルが用いられる。ＲＷモジュール５１の各ポートと伝送路Ｌ１とは、例えば、ＳＭＡ（Ｓｕｂ　Ｍｉｎｉａｔｕｒｅ　Ｔｙｐｅ　Ａ）コネクタなどの同軸コネクタによって接続される。前述した多重信号は、同軸ケーブルの中心導体を通って伝送される。同軸ケーブルのグランドは、ＲＷモジュール５１のポートを介して制御装置５の共通グランドに接続されている。 A coaxial cable is used as the wiring that becomes the transmission line L1. Each port of the RW module 51 and the transmission line L1 are connected by a coaxial connector such as an SMA (Sub Miniature Type A) connector. The multiplex signal described above is transmitted through the central conductor of the coaxial cable. The ground of the coaxial cable is connected to the common ground of the control device 5 via the port of the RW module 51.
　制御装置５は、複数の伝送路Ｌ１の長さの合計が最も短くなる位置に配置される。複数の伝送路Ｌ１は、通過損失等の特性のばらつきを少なくするため、制御装置５と基板４０とを繋ぐ長さが同じであることが望ましい。この場合において、複数の伝送路Ｌ１の長さが同じとは、複数の伝送路Ｌ１の長さの違いが±１０％以内であることを意味する。 The control device 5 is arranged at a position where the total length of the plurality of transmission lines L1 is the shortest. It is desirable that the plurality of transmission lines L1 have the same length connecting the control device 5 and the substrate 40 in order to reduce variations in characteristics such as passage loss. In this case, the same length of the plurality of transmission lines L1 means that the difference in length of the plurality of transmission lines L1 is within ± 10%.
　各伝送路Ｌ１には、各読取装置４が接続されている。前述したように、読取装置４は、基板４０と、基板４０に設けられたスイッチング回路４３と、基板４０に形成された複数のアンテナＡＴと、を備えている。スイッチング回路４３および複数のアンテナＡＴは、基板４０に形成される。図２では、１つのスイッチング回路４３および８つのアンテナＡＴが、同じ１つの基板４０に設けられている。 Each reading device 4 is connected to each transmission line L1. As described above, the reading device 4 includes a substrate 40, a switching circuit 43 provided on the substrate 40, and a plurality of antenna ATs formed on the substrate 40. The switching circuit 43 and the plurality of antenna ATs are formed on the substrate 40. In FIG. 2, one switching circuit 43 and eight antenna ATs are provided on the same one substrate 40.
　スイッチング回路４３は、複数のアンテナＡＴを導通状態または非導通状態に切り替える回路である。例えば、導通状態は、アンテナＡＴが、ＲＦタグＴｇを読み取るための制御装置５（具体的にはＲＷモジュール５１の対応するポート）と導通している状態である。非導通状態は、アンテナＡＴが、ＲＦタグＴｇを読み取るための制御装置５（具体的にはＲＷモジュール５１の対応するポート）と導通していない状態である。 The switching circuit 43 is a circuit that switches a plurality of antenna ATs into a conductive state or a non-conducting state. For example, the conduction state is a state in which the antenna AT is conducting with the control device 5 (specifically, the corresponding port of the RW module 51) for reading the RF tag Tg. The non-conducting state is a state in which the antenna AT is not conducting with the control device 5 (specifically, the corresponding port of the RW module 51) for reading the RF tag Tg.
　図２に示すスイッチング回路４３は、ＳＰｍＴ（単極多投）スイッチであり、１つの共通端子および８つの選択端子を有している。スイッチング回路４３は、１つの伝送路Ｌ１すなわちＲＷモジュール５１の１つのポートに対し、８つのアンテナＡＴを択一的に接続する。スイッチング回路４３は、ＲＷモジュール５１から出力された制御信号に基づいて８つのアンテナＡＴの接続先を切り替え、かつ、接続されたアンテナＡＴにＲＦＩＤ変調波を出力する。なお、スイッチング回路４３は、ＲＷモジュール５１から出力された信号に対しシリアル－パラレル変換を行う機能を備えていてもよい。 The switching circuit 43 shown in FIG. 2 is an SPmT (single pole multi-throw) switch, and has one common terminal and eight selection terminals. The switching circuit 43 selectively connects eight antenna ATs to one transmission line L1, that is, one port of the RW module 51. The switching circuit 43 switches the connection destinations of the eight antenna ATs based on the control signal output from the RW module 51, and outputs the RFID modulated wave to the connected antenna ATs. The switching circuit 43 may have a function of performing serial-parallel conversion on the signal output from the RW module 51.
　複数のアンテナＡＴは、ＲＦタグＴｇからの信号を受信するアンテナである。例えば、ＲＦタグＴｇを読み取る場合、アンテナＡＴは制御信号に基づく電波を放射し、ＲＦタグＴｇを有するＲＦＩＤチップから返ってきた信号を受信する。受信した信号は、スイッチング回路４３および伝送路Ｌ１を介してＲＷモジュール５１に伝送される。これによりＲＷモジュール５１は、ＲＦタグＴｇを読み取り、ＲＦタグＴｇを有するＲＦＩＤチップのメモリに保持されているＥＰＣ（Ｅｌｅｃｔｒｏｎｉｃ　Ｐｒｏｄｕｃｔ　Ｃｏｄｅ）コードやユーザデータ、あるいはフィーダ２０にて供給される部品および収容体１０に収容された部品の情報を取得することができる。 The plurality of antenna ATs are antennas that receive signals from the RF tag Tg. For example, when reading the RF tag Tg, the antenna AT radiates a radio wave based on the control signal and receives the signal returned from the RFID chip having the RF tag Tg. The received signal is transmitted to the RW module 51 via the switching circuit 43 and the transmission line L1. As a result, the RW module 51 reads the RF tag Tg, and the EPC (Electronic Product Code) code and user data stored in the memory of the RFID chip having the RF tag Tg, or the parts and the housing supplied by the feeder 20. Information on the parts housed in 10 can be obtained.
　このように、部品供給システム１は、ＲＦタグＴｇを読み取るために、複数のフィーダ２０に対応して設けられた複数のアンテナＡＴと、複数のアンテナＡＴが形成された少なくとも１つの基板４０と、を備えている。この部品供給システム１によれば、複数のフィーダ２０および複数の収容体１０に付された複数のＲＦタグＴｇを読み取ることができる。これにより、実装装置に供給する部品を管理することができる。 As described above, the component supply system 1 includes a plurality of antenna ATs provided corresponding to the plurality of feeders 20 for reading the RF tag Tg, and at least one substrate 40 on which the plurality of antenna ATs are formed. It is equipped with. According to this component supply system 1, it is possible to read a plurality of RF tags Tg attached to a plurality of feeders 20 and a plurality of housings 10. This makes it possible to manage the parts supplied to the mounting device.
　また、基板４０には、複数のアンテナＡＴを導通状態または非導通状態に切り替えるスイッチング回路４３が設けられている。この部品供給システム１によれば、ＲＦタグＴｇを読み取るためのアンテナＡＴを切り替え、複数のＲＦタグＴｇを読み取ることができる。これにより、実装装置に供給する部品を管理することができる。 Further, the substrate 40 is provided with a switching circuit 43 for switching a plurality of antenna ATs into a conductive state or a non-conducting state. According to this component supply system 1, it is possible to switch the antenna AT for reading the RF tag Tg and read a plurality of RF tags Tg. This makes it possible to manage the parts supplied to the mounting device.
　［２．実装システムの全体構成］
　次に、部品供給システム１を含む実装システム９の全体構成について説明する。 [2. Overall configuration of mounting system]
Next, the overall configuration of the mounting system 9 including the component supply system 1 will be described.
　図３は、部品供給システム１を含む実装システム９を示す概略図である。 FIG. 3 is a schematic diagram showing a mounting system 9 including a component supply system 1.
　実装システム９は、制御装置５と、搬送ロボット６０と、複数の部品供給装置２と、複数の実装装置７からなる実装ライン９０と、を備える。また、実装システム９は、保管エリア９１、準備エリア９２および実装エリア９３の３つのエリアを含んでいる。部品供給システム１は、複数の部品供給装置２および制御装置５によって構成されている。 The mounting system 9 includes a control device 5, a transfer robot 60, a plurality of component supply devices 2, and a mounting line 90 including a plurality of mounting devices 7. Further, the mounting system 9 includes three areas, a storage area 91, a preparation area 92, and a mounting area 93. The component supply system 1 is composed of a plurality of component supply devices 2 and a control device 5.
　実装エリア９３は、実装ライン９０が配置されるエリアである。実装ライン９０は、上流側から搬入されたプリント基板に部品を実装することで実装基板を生産し、生産した実装基板を下流側に搬出する。実装ライン９０は、プリント基板の供給、はんだ印刷作業、部品装着作業およびリフロー作業などを行う各種装置によって実現される。部品装着作業は、実装装置７により行われる。 The mounting area 93 is an area where the mounting line 90 is arranged. The mounting line 90 produces a mounting board by mounting components on a printed circuit board carried in from the upstream side, and carries out the produced mounting board to the downstream side. The mounting line 90 is realized by various devices that supply a printed circuit board, perform solder printing work, component mounting work, reflow work, and the like. The component mounting work is performed by the mounting device 7.
　部品供給装置２は、実装装置７に部品を供給する装置である。部品供給装置２は、例えば、台車で移動可能なフィーダ配置部３０と、フィーダ配置部３０に保持されるフィーダ２０と、フィーダ２０に接続される収容体１０とを備える。フィーダ２０は、フィーダ本体部２１と、フィーダ本体部２１に取付けられるアタッチメント２２とによって構成される。部品供給装置２については、後で詳しく説明する。 The component supply device 2 is a device that supplies components to the mounting device 7. The parts supply device 2 includes, for example, a feeder arranging unit 30 that can be moved by a trolley, a feeder 20 held by the feeder arranging unit 30, and an accommodating body 10 connected to the feeder 20. The feeder 20 is composed of a feeder main body 21 and an attachment 22 attached to the feeder main body 21. The component supply device 2 will be described in detail later.
　保管エリア９１は、部品の収容体１０およびフィーダ２０のアタッチメント２２を保管するエリアである。準備エリア９２は、実装エリア９３の実装ライン９０で用いられるものを事前に準備するためのエリアである。 The storage area 91 is an area for storing the component accommodating body 10 and the attachment 22 of the feeder 20. The preparation area 92 is an area for preparing in advance what is used in the mounting line 90 of the mounting area 93.
　制御装置５は、例えば、生産計画に基づいて、実装ライン９０の生産を制御する。制御装置５は、部品供給装置２に取り付けられている収容体１０内の部品の残数が所定数以下となると、搬送ロボット６０を制御して、部品供給装置２の収容体１０を新しい収容体１０に交換させる。また、制御装置５は、部品供給装置２に取り付けられている収容体１０を他の種類の部品を収容した収容体１０に変更する場合、搬送ロボット６０を制御して、部品供給装置２の収容体１０およびアタッチメント２２を交換させる。このように制御装置５は、実装システム９における部品の補給および部品の種類の変更を管理する。 The control device 5 controls the production of the mounting line 90, for example, based on the production plan. When the remaining number of parts in the housing 10 attached to the parts supply device 2 becomes a predetermined number or less, the control device 5 controls the transfer robot 60 to replace the housing 10 of the parts supply device 2 with a new housing. Exchange for 10. Further, when the control device 5 changes the housing 10 attached to the parts supply device 2 to the housing 10 that houses other types of parts, the control device 5 controls the transfer robot 60 to accommodate the parts supply device 2. The body 10 and the attachment 22 are exchanged. In this way, the control device 5 manages the supply of parts and the change of the type of parts in the mounting system 9.
　［３．部品供給装置の構成］
　次に、部品供給システム１に含まれる部品供給装置２の構成について、図４～図７を参照しながら説明する。なおここでは、部品供給装置２の説明と同時に読取装置４の詳しい構成についても説明する。 [3. Configuration of parts supply equipment]
Next, the configuration of the component supply device 2 included in the component supply system 1 will be described with reference to FIGS. 4 to 7. Here, the detailed configuration of the reading device 4 will be described at the same time as the description of the component supply device 2.

　図４および図５に示すように、部品供給装置２は、複数のフィーダ２０と、複数のフィーダ２０が配置されるフィーダ配置部３０とを有している。前述した基板４０は、フィーダ配置部３０の内部に設けられている。 As shown in FIGS. 4 and 5, the component supply device 2 has a plurality of feeders 20 and a feeder arranging unit 30 in which the plurality of feeders 20 are arranged. The above-mentioned substrate 40 is provided inside the feeder arrangement portion 30.
　複数のフィーダ２０のそれぞれには、部品を収容した収容体１０が接続される。フィーダ２０は、収容体１０に収容された部品を取り出して、実装装置７に供給する。実装装置７は、フィーダ２０から供給された部品をハンドリングし、プリント基板に実装する。 An accommodating body 10 accommodating parts is connected to each of the plurality of feeders 20. The feeder 20 takes out the parts housed in the housing body 10 and supplies them to the mounting device 7. The mounting device 7 handles the components supplied from the feeder 20 and mounts them on the printed circuit board.
　部品は、プリント基板に実装するための実装用の部品である。部品は、例えば、抵抗器、コンデンサなどの電子部品であるが、それに限定されず、プリント基板に実装可能なものであればよい。 The parts are mounting parts for mounting on a printed circuit board. The component is, for example, an electronic component such as a resistor or a capacitor, but is not limited thereto, and may be any component that can be mounted on a printed circuit board.
　収容体１０は、部品を収容する容器であり、例えば、チップ部品をばら積み状態で収容するバルクケース、および、部品付きキャリアテープを巻いた状態で収容するテーピングケースである。収容体１０は、フィーダ２０に対して着脱可能である。各収容体１０には、ＲＦＩＤチップｃｐを搭載したＲＦタグＴｇが貼り付けられている。このＲＦタグＴｇには、収容体１０に収容されている部品に関する情報、例えば、ＲＦタグＴｇを有するＲＦＩＤチップのメモリに保持されているＥＰＣ（Ｅｌｅｃｔｒｏｎｉｃ　Ｐｒｏｄｕｃｔ　Ｃｏｄｅ）コードやユーザデータあるいは部品の種類を示す情報（識別情報）、数量（残数）を示す情報、使用期限を示す情報などが含まれている。 The accommodating body 10 is a container for accommodating parts, for example, a bulk case for accommodating chip parts in a bulk state and a taping case for accommodating a carrier tape with parts wrapped around them. The housing 10 is removable with respect to the feeder 20. An RF tag Tg on which an RFID chip cp is mounted is attached to each housing 10. The RF tag Tg contains information about the parts housed in the housing 10, for example, an EPC (Electronic Product Code) code, user data, or a type of part held in the memory of the RFID chip having the RF tag Tg. Information indicating information (identification information), information indicating quantity (remaining number), information indicating expiration date, etc. are included.
　フィーダ２０は、例えば、振動または間欠送り機構によって部品を搬送する装置である。なお、フィーダ２０は、例えば、エアー供給、磁力、コンベア等によって部品を搬送してもよい。フィーダ２０のアタッチメント２２またはフィーダ本体部２１には、ＲＦＩＤチップｃｐを搭載したＲＦタグＴｇが貼り付けられている。このＲＦタグＴｇには、フィーダ２０で供給可能な部品に関する情報が含まれている。また、このＲＦタグＴｇには、フィーダ２０の識別情報、使用履歴などの情報が含まれていてもよい。 The feeder 20 is a device that conveys parts by, for example, a vibration or an intermittent feed mechanism. The feeder 20 may convey parts by, for example, air supply, magnetic force, conveyor, or the like. An RF tag Tg on which an RFID chip cp is mounted is attached to the attachment 22 of the feeder 20 or the feeder main body 21. The RF tag Tg contains information about the parts that can be supplied by the feeder 20. Further, the RF tag Tg may include information such as identification information and usage history of the feeder 20.
　図５には、１台の実装装置７に、両側から２台の部品供給装置２が接続されている例が示されている。ここでは１台の部品供給装置２に着目して説明する。図５に示すように、フィーダ配置部３０に配置されている複数のフィーダ２０は、第１方向ｄ１に沿って並んで配列されている。各フィーダ２０は、例えば、フィーダ２０が配列されている第１方向ｄ１と直交する第２方向ｄ２に沿って、部品を搬送および供給する。なお、第２方向ｄ２は、基板４０の主面に沿う方向であってかつ第１方向ｄ１に直交する方向である。 FIG. 5 shows an example in which two component supply devices 2 are connected to one mounting device 7 from both sides. Here, the description will be focused on one component supply device 2. As shown in FIG. 5, the plurality of feeders 20 arranged in the feeder arrangement unit 30 are arranged side by side along the first direction d1. Each feeder 20 transports and supplies parts, for example, along a second direction d2 orthogonal to the first direction d1 in which the feeder 20 is arranged. The second direction d2 is a direction along the main surface of the substrate 40 and orthogonal to the first direction d1.
　図６に示すように、フィーダ配置部３０は、複数のスロット３１を有している。スロット３１は、フィーダ２０をフィーダ配置部３０に取り付けるための取り付け口であり、フィーダ配置部３０の上側領域に設けられている。スロット３１は、例えば、穴、溝または窪みなどの開口である。スロット３１には、フィーダ２０の外枠、フィーダ２０に設けられた丸ピン、角ピン等が嵌め込まれ、フィーダ２０が位置決めされる。フィーダ２０は、スロット３１に対して着脱可能である。複数のフィーダ２０は、複数のスロット３１に一対一の対応で取り付けられる。 As shown in FIG. 6, the feeder arrangement unit 30 has a plurality of slots 31. The slot 31 is an attachment port for attaching the feeder 20 to the feeder arrangement portion 30, and is provided in the upper region of the feeder arrangement portion 30. The slot 31 is, for example, an opening such as a hole, groove or depression. The outer frame of the feeder 20, a round pin provided on the feeder 20, a square pin, and the like are fitted into the slot 31, and the feeder 20 is positioned. The feeder 20 is removable from the slot 31. The plurality of feeders 20 are attached to the plurality of slots 31 in a one-to-one correspondence.
　図４および図５に示すように、フィーダ配置部３０の内部には、水平方向に沿った基板４０が設けられている。すなわち基板４０は、第１方向ｄ１および第２方向ｄ２の両方に沿い、鉛直方向である第３方向ｄ３に直交するように配置されている。なお、基板４０は、水平方向に限られず、フィーダ配置部３０の内部において、傾いてまたは垂直方向に沿って設けられていてよい。 As shown in FIGS. 4 and 5, a substrate 40 along the horizontal direction is provided inside the feeder arrangement portion 30. That is, the substrate 40 is arranged along both the first direction d1 and the second direction d2 so as to be orthogonal to the third direction d3 which is the vertical direction. The substrate 40 is not limited to the horizontal direction, and may be provided inside the feeder arrangement portion 30 at an angle or along a vertical direction.
　複数の基板４０のそれぞれには、複数のアンテナＡＴが形成されている。図５に示すように、複数の基板４０の間には、隣の基板４０のアンテナＡＴとの電波干渉を抑制するための遮蔽部材ｓ１（図５の太破線）が設けられている。遮蔽部材ｓ１は、例えば、金属板または金属メッシュであり、フィーダ配置部３０内に設けられる。なお、図５には、フィーダ配置部３０内に２つの基板４０が設けられている例が示されているが、それに限られず、フィーダ配置部３０に１つの基板４０が設けられ、その１つの基板４０に２つのスイッチング回路４３および１６基のアンテナＡＴが設けられていてもよい。 A plurality of antenna ATs are formed on each of the plurality of substrates 40. As shown in FIG. 5, a shielding member s1 (thick broken line in FIG. 5) for suppressing radio wave interference with the antenna AT of the adjacent substrate 40 is provided between the plurality of substrates 40. The shielding member s1 is, for example, a metal plate or a metal mesh, and is provided in the feeder arrangement portion 30.

The land 41, the lead wire 45, the ground plane 46, and the antenna AT are made of the same electrode material and have the same thickness.
　ランド４１は、信号の出入口であり、第２方向ｄ２における基板４０の一方の端部に設けられている。ランド４１は、１本の同軸ケーブルからなる伝送路Ｌ１に接続されている。ランド４１には、ＲＷモジュール５１から出力された多重信号が入力される。なお、伝送路Ｌ１とランド４１とは、同軸コネクタを介して接続されていてもよい。 The land 41 is a signal entrance / exit, and is provided at one end of the substrate 40 in the second direction d2.

The multiplex signal output from the land 41 is transmitted to the first relay line 42. The first relay line 42 is, for example, a wiring pattern formed on the substrate 40, but may be a coaxial cable.
　スイッチング回路４３およびアンテナＡＴは、第２中継線４４および引き出し配線４５によって接続されている。第２中継線４４は、スイッチング回路４３と引き出し配線４５とを繋ぐ配線である。第２中継線４４は、例えば基板４０に形成された配線パターンであるが、同軸ケーブルであってもよい。引き出し配線４５は、第２中継線４４とアンテナＡＴとを繋ぐ配線パターンである。引き出し配線４５は、基板４０に形成された配線パターンである。引き出し配線４５は、第２方向ｄ２に沿って設けられ、アンテナＡＴの一方の端部に接続されている。 The switching circuit 43 and the antenna AT are connected by a second relay line 44 and a lead-out wiring 45. The second relay line 44 is a wiring connecting the switching circuit 43 and the lead-out wiring 45. The second relay line 44 is, for example, a wiring pattern formed on the substrate 40, but may be a coaxial cable.

　本実施の形態では、スイッチング回路４３のスイッチング動作によって、複数のアンテナＡＴとランド４１間が非導通状態および導通状態に切り替えられる。具体的には、ＲＷモジュール５１から送信された多重信号に含まれる制御信号によって、スイッチング回路４３が作動し、接続先のアンテナＡＴが順次切り替えられる。例えば、１つのアンテナＡＴが導通状態になっているときは、他のアンテナＡＴは非導通状態となる。ＲＷモジュール５１は、導通状態にあるアンテナＡＴからＲＦＩＤ変調波を放射させることで、ＲＦＩＤチップｃｐと通信を行い、ＲＦＩＤチップｃｐに含まれる情報を取得する。 In the present embodiment, the switching operation of the switching circuit 43 switches between the plurality of antenna ATs and the land 41 into a non-conducting state and a conducting state. Specifically, the switching circuit 43 is operated by the control signal included in the multiplex signal transmitted from the RW module 51, and the antenna AT of the connection destination is sequentially switched. For example, when one antenna AT is in a conductive state, the other antenna AT is in a non-conducting state. The RW module 51 communicates with the RFID chip cp by radiating an RFID modulated wave from the antenna AT in the conductive state, and acquires the information contained in the RFID chip cp.

As described above, the two antennas adjacent to each other in the first direction d1 may be arranged so as to be offset from each other in the second direction d2 orthogonal to the first direction d1 and along the substrate 40.

　複数のグランド電極４７Ａのそれぞれは、アンテナＡＴに沿って第２方向ｄ２に直線状に延びている。グランド電極４７Ａの長さは、第２方向ｄ２において、アンテナＡＴの長さと同じである。グランド電極４７Ａは、アンテナＡＴに接触しておらず、アンテナＡＴに対して間隔を空けて配置されている。また、グランド電極４７Ａは、第１方向ｄ１において、複数のアンテナＡＴの間に設けられている。グランド電極４７ＡおよびアンテナＡＴは、同じ電極材料によって形成され、同じ厚みを有している。なお、グランド電極４７Ａは、アンテナＡＴよりも厚くてもよい。グランド電極４７Ａは、ジャンパー線、または、裏面配線およびスルーホール配線を介して同軸ケーブルのグランドに接続される。 Each of the plurality of ground electrodes 47A extends linearly in the second direction d2 along the antenna AT. The length of the ground electrode 47A is the same as the length of the antenna AT in the second direction d2. The ground electrode 47A is not in contact with the antenna AT and is arranged at a distance from the antenna AT. Further, the ground electrode 47A is provided between the plurality of antennas AT in the first direction d1.

　このように、読取装置４Ａが上記グランド電極４７Ａを備えることで、ＲＦタグＴｇの信号を受信するアンテナＡＴが、上記ＲＦタグＴｇの隣に位置するＲＦタグＴｇの信号まで受信することを抑制できる。これによれば、誤検出を抑制し、供給すべき部品のみの情報を取得することができる。これにより、実装装置７に供給する部品を管理することができる。また、隣接するＲＦタグＴｇの読み取りが抑制される分、ＲＷモジュール５１の送信出力を大きくすることができ、供給すべき部品の情報取得に有利となる。 As described above, by providing the reading device 4A with the ground electrode 47A, it is possible to suppress the antenna AT that receives the signal of the RF tag Tg from receiving the signal of the RF tag Tg located next to the RF tag Tg. .. According to this, it is possible to suppress erroneous detection and acquire information on only the parts to be supplied. This makes it possible to manage the parts supplied to the mounting device 7. Further, since the reading of the adjacent RF tag Tg is suppressed, the transmission output of the RW module 51 can be increased, which is advantageous for acquiring information on the parts to be supplied.
