例えば、工場にて通信装置を取付けて出荷する場合、出荷前に通信装置の配線を行い、商用試験にて通信装置の導通状態を確認する。導通状態を保証するために、導通試験後は通信装置の配線を外さずに出荷することが望ましい。ここで、油漏れ等の異常箇所の目視や、モータの銘版等の確認、試験結果が不合格となった場合の修正工数の低減といった理由から、商用試験は、流体機械の筐体上面を含む底面以外の筐体面が組付いていない状態で行われることが望ましい。すなわち、商用試験後に筐体上面を流体機械に取付けた後に、配線を外さずに配線済みの通信装置を筐体上面に取付け可能であり、なおかつ配線が外部に出さないような取付機構、取付方法が必要となる。このような構成について、特許文献1は考慮されていない。 For example, when a communication device is installed at a factory and shipped, the wiring of the communication device is performed before shipment, and the conduction state of the communication device is confirmed by a commercial test. In order to guarantee continuity, it is desirable to ship the communication device without disconnecting the wiring after the continuity test. Here, for reasons such as visual inspection of abnormal points such as oil leaks, confirmation of motor nameplates, etc., and reduction of man-hours for correction when the test result fails, the upper surface of the housing of the fluid machinery is used in the commercial test. It is desirable to perform the assembly in a state in which the housing surfaces other than the bottom surface including the housing are not assembled. That is, after the upper surface of the housing is attached to the fluid machine after the commercial test, it is possible to install the wired communication device on the upper surface of the housing without removing the wiring, and furthermore, the mounting mechanism and the mounting method that prevent the wiring from coming out. Is required. Patent Document 1 does not consider such a configuration.

本発明の目的の一つは、流体機械の商用試験時の作業性を損なわず、通信装置の配線を流体機械の外部に出さず、流体機械の通信装置の導通状態を保証した状態で流体装置を出荷することが可能となる流体機械及びその組立方法を提供することである。 One of the objects of the present invention is to provide a fluid device in a state in which the continuity of the communication device of the fluid machine is guaranteed without impairing workability during commercial testing of the fluid machine, without exposing the wiring of the communication device to the outside of the fluid machine. To provide a fluid machine and a method for assembling the same, which can be shipped.

本発明は、上記背景技術及び課題に鑑み、その一例を挙げるならば、筐体を備え通信装置を有した流体機械の組立方法であって、筐体は開口部を有し、筐体を取付ける前に制御部と通信装置を配線して接続し、筐体を取付け、通信装置を、配線を取り外すことなく開口部をくぐらせ筐体の外部に取り出し、通信装置を、開口部を覆うように筐体に取り付ける。 The present invention has been made in view of the above-described background art and problems. Connect the control unit and the communication device by wiring, attach the housing, take the communication device out of the housing through the opening without removing the wiring, and cover the opening with the communication device. Install in the housing.

以下に、本発明の実施例について図面を用いて詳細に説明する。なお、以下の実施例においては本発明の実施の一例として圧縮気体を生成する圧縮機を用いた例を示す。また、圧縮機としては、空気等の気体を吸い込み圧縮空気を吐き出す容積式や回転式(遠心式)といった種々の圧縮機構を有するものを適用することができる。また、本発明は圧縮機に限定するものではなく、ポンプや膨張機、油圧モータ、送風機、真空ポンプ、冷凍機など流体機械一般に適用可能である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following examples, an example using a compressor for generating compressed gas is shown as an example of implementation of the present invention. Further, as the compressor, a compressor having various compression mechanisms such as a positive displacement type and a rotary type (centrifugal type) that sucks gas such as air and discharges compressed air can be applied. Moreover, the present invention is not limited to compressors, but can be applied to general fluid machinery such as pumps, expanders, hydraulic motors, blowers, vacuum pumps, and refrigerators.

図1に、本実施例における圧縮機の全体外観図を示す。図1において、圧縮機1は、通信装置である、通信電波を送受するアンテナを備えたアンテナホルダ20と、これを取付ける圧縮機筐体上面30を主に備える。 FIG. 1 shows an overall external view of the compressor in this embodiment. In FIG. 1, the compressor 1 mainly includes an antenna holder 20 having an antenna for transmitting and receiving communication radio waves, which is a communication device, and a compressor housing upper surface 30 to which the antenna holder 20 is attached.

すなわち、例えば、クラウド監視システムに圧縮機を対応させるにあたり、圧縮機に通信のためのアンテナを搭載させる必要がある。アンテナの設置位置について、電波が遮蔽されず、できるだけ全方位の電波を取得するために、圧縮機の上面に設置する必要がある。また、工場にてアンテナを取付けて出荷するにあたり、輸送時の破損を防ぐために、できるだけアンテナ自体の高さを抑えることが望ましい。加えて、安全性と外観との観点からアンテナの配線は圧縮機の外部には出さないようにすることが望ましい。以上から、アンテナは薄い平面の基板アンテナを使用し、基板アンテナを保持する樹脂製のアンテナホルダ20を圧縮機筐体上面30に設置する。これにより、圧縮機1はアンテナを介して圧縮機の稼働データを送信することができる。 That is, for example, in making a compressor compatible with a cloud monitoring system, it is necessary to mount an antenna for communication on the compressor. Regarding the installation position of the antenna, it is necessary to install it on the top surface of the compressor so that radio waves are not shielded and radio waves are acquired in all directions as much as possible. Also, when the antenna is installed at the factory and shipped, it is desirable to keep the height of the antenna as low as possible in order to prevent damage during transportation. In addition, from the viewpoint of safety and appearance, it is desirable not to expose the antenna wiring to the outside of the compressor. As described above, a thin planar board antenna is used as the antenna, and the antenna holder 20 made of resin for holding the board antenna is installed on the upper surface 30 of the compressor housing. Thereby, the compressor 1 can transmit the operation data of the compressor via the antenna.

ここで、アンテナ搭載の圧縮機を出荷するには、出荷前の商用試験時においてアンテナと圧縮機制御部とを配線接続し、アンテナの導通状態を確認する必要がある。導通状態を保証するためにも、商用試験後には圧縮機制御部とアンテナは接続されたままにすることが望ましい。また商用試験時には、油漏れ等の異常箇所の目視、モータの銘版等の確認、試験結果がNGとなった場合の修正工数の低減といった理由から、圧縮機筐体の上面を含む全面を外した状態とする。すなわち、商用試験後に圧縮機に筐体上面を取付けた後に、配線された状態のアンテナをアンテナホルダを介して筐体上面に取付けが可能であり、なおかつ配線が外に出ないような取付機構、取付方法が求められる。 Here, in order to ship a compressor equipped with an antenna, it is necessary to wire-connect the antenna and the compressor controller and check the conduction state of the antenna during a commercial test before shipping. It is desirable to leave the compressor control and antenna connected after commercial testing to ensure continuity. In addition, during commercial tests, the entire surface of the compressor housing, including the top surface, was removed from the outside for reasons such as visual inspection of abnormalities such as oil leaks, confirmation of motor nameplates, and reduction of man-hours for corrections when test results are NG. state. That is, after the top surface of the housing is attached to the compressor after the commercial test, the antenna in a wired state can be attached to the top surface of the housing via the antenna holder, and the wiring does not protrude. A mounting method is required.

図2は、本実施例における圧縮機のアンテナホルダの組付手順を示す模式図であり、アンテナ取り付け部分を拡大した図を示している。 FIG. 2 is a schematic diagram showing the assembly procedure of the antenna holder of the compressor in this embodiment, showing an enlarged view of the antenna mounting portion.

前述の通り、商用試験でアンテナの導通試験を行うため、アンテナが配線されている状態でアンテナを装着したアンテナホルダを圧縮機筐体上面に取付ける必要がある。そこで、筐体上面にアンテナホルダ取付穴31を設け、アンテナホルダ取付穴31の内側からアンテナホルダを通すようにすることで、配線済みのアンテナを、外に配線が出ることなく取付可能とした。以下、図2を用いて取付手順を説明する。 As described above, in order to conduct a continuity test of the antenna in the commercial test, it is necessary to attach the antenna holder with the antenna to the upper surface of the compressor housing while the antenna is wired. Therefore, by providing an antenna holder mounting hole 31 on the upper surface of the housing and allowing the antenna holder to pass from the inside of the antenna holder mounting hole 31, the wired antenna can be mounted without the wiring coming out. The mounting procedure will be described below with reference to FIG.

まず、(a)は、アンテナを備えたアンテナホルダ20が商用試験を終えて圧縮機制御部40と配線されている状態であり、商用試験の後工程で筐体上面30が圧縮機筐体として組み付けられている状態である。なお、筐体上面30にはアンテナホルダ取付穴31が設けられている。 First, (a) shows a state in which the antenna holder 20 equipped with an antenna is wired to the compressor control unit 40 after completing the commercial test, and the housing upper surface 30 is used as the compressor housing in the post-commercial test process. It is in an assembled state. An antenna holder mounting hole 31 is provided in the upper surface 30 of the housing.

その後、(b)で、アンテナホルダ20を、配線されたまま、筐体上面30のアンテナホルダ取付穴31に通す。すなわち、アンテナホルダ20を、配線を取り外すことなくアンテナホルダ取付穴31をくぐらせ筐体の外部に取り出す。このとき、アンテナホルダ20は、傷つき防止のために保護フィルム(ビニール袋)で覆われている。そして、(c)で、アンテナホルダ20が、アンテナホルダ取付穴31を通過した後、保護フィルム(ビニール袋)が外され、圧縮機1の筐体内部から筐体外部に出される。そして、(d)で、アンテナホルダ20は、アンテナホルダ取付穴31を覆うように取付けられ、筐体上面30に設置される。このように、圧縮機1の組立工程において、アンテナホルダ取付穴31を有する筐体上面30に配線済みアンテナを装着したアンテナホルダ20が取付けられる。 After that, in (b), the antenna holder 20 is passed through the antenna holder mounting hole 31 of the upper surface 30 of the housing while the wiring is maintained. That is, the antenna holder 20 is passed through the antenna holder mounting hole 31 and taken out of the housing without removing the wiring. At this time, the antenna holder 20 is covered with a protective film (plastic bag) to prevent damage. Then, in (c), after the antenna holder 20 passes through the antenna holder mounting hole 31, the protective film (plastic bag) is removed and the antenna holder 20 is taken out from the inside of the housing of the compressor 1 to the outside of the housing. Then, in (d), the antenna holder 20 is attached so as to cover the antenna holder attachment hole 31 and is installed on the upper surface 30 of the housing. As described above, in the assembly process of the compressor 1, the antenna holder 20 with the wired antenna mounted thereon is attached to the top surface 30 of the housing having the antenna holder attachment hole 31. As shown in FIG.

図3は、本実施例におけるアンテナホルダ20の模式図である。また、図4は、本実施例におけるアンテナホルダ20の分解図である。図4に示すように、アンテナホルダ20は、カバー21と基板アンテナ22とアンテナ固定部23から構成される。そして、基板アンテナ22は配線24で接続端子25に接続されている。また、図3に示すように、接続端子25はアンテナ固定部23に固定されている。圧縮機制御部と配線する場合は、圧縮機制御部の配線26の接続端子を基板アンテナ22の接続端子25と接続させる。 FIG. 3 is a schematic diagram of the antenna holder 20 in this embodiment. Moreover, FIG. 4 is an exploded view of the antenna holder 20 in this embodiment. As shown in FIG. 4, the antenna holder 20 is composed of a cover 21, a substrate antenna 22, and an antenna fixing portion . The board antenna 22 is connected to the connection terminal 25 by the wiring 24 . Also, as shown in FIG. 3, the connection terminal 25 is fixed to the antenna fixing portion 23 . When wiring with the compressor control section, the connection terminal of the wiring 26 of the compressor control section is connected to the connection terminal 25 of the board antenna 22 .

アンテナホルダ20の形状は、図3、図4に示すように、横幅をW1、縦幅をL1、高さをH1とすると、それぞれの長さの関係は、H1<L1<W1である。アンテナホルダ20をアンテナホルダ取付穴31に通すときは、アンテナホルダ20の最長の辺であるW1が含まれないL1-H1平面が筐体上面3と水平となるようにする。 As shown in FIGS. 3 and 4, the shape of the antenna holder 20 has a width of W1, a length of L1, and a height of H1, where H1<L1<W1. When the antenna holder 20 is passed through the antenna holder mounting hole 31, the L1-H1 plane that does not include W1, which is the longest side of the antenna holder 20, is made horizontal to the upper surface 3 of the housing.

図5は、本実施例における圧縮機の筐体上面30のアンテナホルダ取付穴部分の上面図である。筐体上面30は、アンテナホルダ20を取付けるためのアンテナホルダ取付穴31を有する。アンテナホルダ取付穴31の横幅をW2、縦幅をL2とする。アンテナホルダ20の横幅W1と縦幅L1との関係は、W2<W1、L2<L1である。これは、アンテナホルダ20をアンテナホルダ取付穴31に取付けた時、アンテナホルダ取付穴31がアンテナホルダ20で完全に覆われるようにするためである。すなわち、アンテナホルダ取付穴31は、アンテナホルダ20を取付け後の面積よりも小さい取付け穴とする。また、アンテナホルダ20をアンテナホルダ取付穴31に通すために、アンテナホルダ20のL1-H1平面の寸法が通過するようなW2、L2とする必要がある。 FIG. 5 is a top view of the antenna holder mounting hole portion of the housing top surface 30 of the compressor in this embodiment. The housing upper surface 30 has an antenna holder mounting hole 31 for mounting the antenna holder 20 . Let W2 be the width of the antenna holder mounting hole 31, and L2 be the length thereof. The relationship between the width W1 and the length L1 of the antenna holder 20 is W2<W1 and L2<L1. This is to ensure that the antenna holder mounting hole 31 is completely covered with the antenna holder 20 when the antenna holder 20 is mounted in the antenna holder mounting hole 31 . That is, the antenna holder mounting hole 31 has a smaller area than the area after mounting the antenna holder 20 . Also, in order to pass the antenna holder 20 through the antenna holder mounting hole 31, it is necessary to set W2 and L2 so that the dimension of the L1-H1 plane of the antenna holder 20 passes through.

このように、本実施例によれば、配線済みアンテナを装着したアンテナホルダを、圧縮機の筐体上面が取付けられた後に筐体上面に取付けが可能であり、なおかつアンテナの配線を圧縮機の外部に出さず、圧縮機のアンテナの導通状態を保証した状態で圧縮機を出荷することが可能となる。 As described above, according to the present embodiment, the antenna holder with the pre-wired antenna attached can be attached to the top surface of the casing after the top surface of the casing of the compressor has been attached, and the wiring of the antenna can be connected to the top surface of the compressor. It is possible to ship the compressor in a state in which the conduction state of the antenna of the compressor is guaranteed without exposing it to the outside.

実施例1では、基板アンテナをアンテナホルダ20に装着した状態で、アンテナホルダ取付穴31に通すことで対応した。これに対して、本実施例では、基板アンテナは、アンテナホルダ20に装着せずにアンテナホルダ取付穴31を通す例について説明する。 In the first embodiment, the substrate antenna is mounted on the antenna holder 20 and is passed through the antenna holder mounting hole 31 . On the other hand, in this embodiment, an example in which the substrate antenna is passed through the antenna holder mounting hole 31 without being attached to the antenna holder 20 will be described.

本実施例では、実施例1における図2の(a)において、アンテナと圧縮機制御部40が配線されている状態ではあるが、アンテナホルダ20にアンテナは装着されていない状態とする。 In this embodiment, the antenna and the compressor control unit 40 are wired in FIG. 2A in the first embodiment, but the antenna is not attached to the antenna holder 20 .

そして、図4に示すアンテナである基板アンテナ22のみを、配線されたまま筐体上面30のアンテナホルダ取付穴31に通す。そして、その後、アンテナホルダ取付穴31を通過した基板アンテナ22をアンテナホルダ20に装着し、アンテナホルダ20をアンテナホルダ取付穴31に取付ける。 Then, only the board antenna 22, which is the antenna shown in FIG. After that, the board antenna 22 passed through the antenna holder mounting hole 31 is mounted on the antenna holder 20 , and the antenna holder 20 is mounted on the antenna holder mounting hole 31 .

このように、本実施例ではアンテナホルダ20に装着しない基板アンテナ22のみをアンテナホルダ取付穴31に通すので、アンテナホルダ取付穴31を基板アンテナ22が通過するような寸法とすればよい。よって、アンテナホルダ取付穴31を通過した後に基板アンテナ22をアンテナホルダ20に装着するので、実施例1に比べて作業性は劣るものの、アンテナホルダ取付穴31を小さくできるという利点がある。 As described above, in this embodiment, only the board antenna 22 that is not attached to the antenna holder 20 is passed through the antenna holder mounting hole 31, so the antenna holder mounting hole 31 may be dimensioned so that the board antenna 22 can pass therethrough. Therefore, since the substrate antenna 22 is attached to the antenna holder 20 after passing through the antenna holder mounting hole 31, workability is inferior to that of the first embodiment, but there is an advantage that the antenna holder mounting hole 31 can be made smaller.

以上、実施例について説明したが、本発明は上記した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施例は本発明をわかりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施例の構成に他の実施例の構成を加える事も可能である。 Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations. Moreover, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment.
