Description

【０００１】
【発明の属する技術分野】
本発明はエレクトロフュージョン継手用コントローラに関する。詳しくは、ガス管や水道管に用いられるプラスチック管の接続に用いられるエレクトロフュージョン継手（以下、ＥＦ継手という）に供給する電力を制御するＥＦ継手用コントローラに関する。
【０００２】
【従来の技術】
従来、上下水道やガス管などのプラスチック管による配管工事においては、プラスチック製のＴ継手、エルボ継手、ソケット継手、サドル継手等を用い、その内面及びプラスチック管外周面をヒータにより加熱溶融し、その状態で継手にプラスチック管を差し込んで接合していた。しかし最近では作業性及び接続品質を向上するためエレクトロフュージョン方式（以下、ＥＦ方式という）による接続方法が採用されている。
【０００３】
この、ＥＦ方式によるプラスチック管の接続方法は、図２に示すように接続すべき２本のプラスチック管１，１′を接続するのにＥＦ継手を用いる。このＥＦ継手２は予めコイル状に巻回された電熱線３が埋設されたプラスチック管であり、該電熱線の両端はターミナルピン４，５に接続されている。
【０００４】
そして、ＥＦ継手２の両端から接続すべきプラスチック管１，１′をストッパ２ａに突き当たるまで挿入しておき、ターミナルピン４，５にＥＦ継手用コントローラ６からのコード７，７′を接続し、電源コード８を電源に接続して電源を入れ、そのＥＦ継手２に決められた電流を決められた時間通電する。これにより電熱線３は発熱し、ＥＦ継手２の内面及びプラスチック管１，１′の外周面を溶融して両者を接合するのである。
【０００５】
【発明が解決しようとする課題】
上記従来のＥＦ継手用コントローラにおいては、ＥＦ継手の施工情報はコントローラ自身には何も入力されていなかった。このため後日継手部に故障が発生した場合の原因調査に必要な施工情報の収集管理が不十分であるという問題があった。
【０００６】
本発明は上記従来の問題点に鑑み、ＥＦ継手を用いたプラスチック管の接続工事において、その施工情報を確実に記録保存できるＥＦ継手用コントローラを実現することを目的とする。
【０００７】
【課題を解決するための手段】
本発明のＥＦ継手用コントローラに於いては、継手に挿入されたプラスチック製パイプを該継手内に組み込まれた電熱線により融着させて接続する工法に使用され、該電熱線に供給する電力を制御するエレクトロフュージョン継手用コントローラであって、給電出力値を設定する給電出力設定手段１１と、その設定値に従って給電出力する給電出力手段１２と、管接続の施工情報が入力される情報入力手段１３と、該情報入力手段１３に入力された情報を記憶するデータ収集用記憶装置１４とを具備し、さらに該データ収集用記憶装置１４の作動準備ができていないときは、継手への給電出力を許可しないようにしたインターロック手段１５を具備してなるエレクトロフュージョン継手用コントローラにおいて、前記インターロック手段は、データ収集用記憶装置に記憶媒体がセットされていないとき、又は記録媒体がセットされていても、その記憶容量が不足状態の時には、前記給電出力手段からの給電出力を遮断する手段を有することを特徴とする。
【０００９】
この構成を採ることにより、ＥＦ継手を用いたプラスチック管の接続工事において、その施工情報を確実に記録保存できるＥＦ継手用コントローラが得られる。
【００１０】
【発明の実施の形態】
図１は本発明の実施の形態のＥＦ継手用コントローラ１０を示すブロック図である。同図において、１１はＥＦ継手へ供給する電力の給電出力値を設定する給電出力設定手段であり、１２は該給電出力設定手段１１に接続され、且つ該給電出力設定手段１１の指示によりＥＦ継手に給電出力を出力する給電出力手段である。また、１３は施工情報が入力される情報入力手段であり、１４は該情報入力手段１３に接続され施工情報を記録するデータ収集用記録装置である。
【００１１】
また、前記給電出力手段１２の出力配線の途中には本発明の特徴であるインターロック手段１５が挿入されている。この、インターロック手段１５は、情報入力手段１３からの複数の情報に対応する信号およびデータ収集用記録装置１４の準備完了により送出される信号とのアンドをとるＡＮＤ回路１６と、該ＡＮＤ回路１６よりの信号により駆動され、前記給電出力手段１２から出力される給電出力をオン・オフするスイッチ１７とを具備している。
【００１２】
そして、情報入力手段１３に情報を入力する手段としては、バーコード、ＩＤカード、キー入力、通信手段を介した遠隔からの情報源等が用いられる。従って情報入力手段１３には情報を入力する手段に対応して、バーコードリーダー、磁気読取装置、キーボード、モデム等の少なくとも１つを具備する必要がある。
【００１３】
また、情報入力手段１３に入力する施工情報としては、▲１▼工事責任者情報、▲２▼工事を明示する情報（工事会社名、工事番号、工事日時、工事場所等）が用いられる。これらの情報は単独、もしくは組み合わせで入力してもよい。そして、これらの情報が入力されると、それぞれ信号をＡＮＤ回路１６に送出するようになっている。
【００１４】
また、データ収集用記録装置１４には記録媒体としてフロッピーディスク、メモリーカード等を用いる記録装置が用いられる。そして、これらの記録媒体がセットされていないとき、または記録媒体がセットされていてもその記録媒体の記録容量が不足状態にあるときは、ＡＮＤ回路１６には信号を送出しないようになっており、記録媒体がセットされ且つセットされた記録媒体の記憶容量が十分にあるときのみＡＮＤ回路１６に信号を送出するようになっている。
【００１５】
このように構成された本実施の形態の作用を次に説明する。先ず給電出力手段１２の出力ケーブルをＥＦ継手に接続しておく。次いで給電出力設定手段１１により給電出力を設定し、給電出力手段１２より出力させる。このときスイッチ１７はＡＮＤ回路１６よりの信号がないためオフとなっている。このため、給電出力手段１２よりの出力はスイッチ１７により遮断されＥＦ継手には給電されない。
【００１６】
次いで情報入力手段１３に所定数の施工情報が入力されると、該情報入力手段１３からは入力情報に対応した信号がＡＮＤ回路１６に送られる。また、データ収集用記憶装置１４に記憶媒体がセットされ、且つ記憶媒体の容量不足がないことが確認され、準備が完了されると該データ収集用記憶装置１４からＡＮＤ回路１６に信号が送られる。同時に、データ収集用記憶装置１４は情報入力手段１３に入力されている施工情報を記録する。
【００１７】
ＡＮＤ回路１６は、これら情報入力手段１３及びデータ収集用記憶装置１４からの信号が全て揃うとスイっチ１７に信号を送り該スイッチ１７をオンさせる。そして、スイッチ１７がオンすると給電出力手段１２からの給電出力を通過させＥＦ継手に出力する。これによりＥＦ継手の電熱線は発熱し継手の内面及び接続するプラスチック管の外周面を溶融して接続を行うのである。
【００１８】
【発明の効果】
本発明のＥＦ継手用コントローラによれば、所定の施工情報が全て入力され、且つデータ収集用記憶装置の準備が完了した場合のみＥＦ継手への給電出力が出力されようにしたことにより、データ収集用記憶装置により確実に施工情報が記録保存でき、ＥＦ継手によるプラスチック管の接続の品質管理に寄与することが可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a controller for an electrofusion joint. More specifically, the present invention relates to an EF joint controller that controls electric power supplied to an electrofusion joint (hereinafter, referred to as an EF joint) used to connect a plastic pipe used for a gas pipe or a water pipe.
[0002]
[Prior art]
Conventionally, in plumbing work with plastic pipes such as water and sewage and gas pipes, plastic T-joints, elbow joints, socket joints, saddle joints, and the like are used, and the inner surface and the outer peripheral surface of the plastic tube are heated and melted by a heater. In this state, a plastic tube was inserted into the joint and joined. However, recently, in order to improve workability and connection quality, a connection method using an electrofusion method (hereinafter, referred to as an EF method) has been adopted.
[0003]
In the method of connecting plastic pipes by the EF method, an EF joint is used to connect two plastic pipes 1 and 1 'to be connected as shown in FIG. The EF joint 2 is a plastic tube in which a heating wire 3 wound in a coil shape in advance is embedded, and both ends of the heating wire are connected to terminal pins 4 and 5.
[0004]
Then, the plastic pipes 1, 1 'to be connected from both ends of the EF joint 2 are inserted until they abut against the stopper 2a, and the cords 7, 7' from the EF joint controller 6 are connected to the terminal pins 4, 5, The power supply cord 8 is connected to a power supply and turned on, and a predetermined current is supplied to the EF joint 2 for a predetermined time. As a result, the heating wire 3 generates heat and melts the inner surface of the EF joint 2 and the outer peripheral surfaces of the plastic pipes 1 and 1 'to join them.
[0005]
[Problems to be solved by the invention]
In the above-mentioned conventional EF joint controller, no construction information of the EF joint is input to the controller itself. Therefore, there is a problem that collection and management of construction information necessary for investigating a cause when a failure occurs in the joint part at a later date is insufficient.
[0006]
The present invention has been made in view of the above-described conventional problems, and has as its object to realize an EF joint controller capable of reliably recording and saving construction information in a connection work of a plastic pipe using an EF joint.
[0007]
[Means for Solving the Problems]
In the controller for an EF joint according to the present invention, a plastic pipe inserted into the joint is used for a method of fusing and connecting the plastic pipe with a heating wire incorporated in the joint, and the electric power supplied to the heating wire is used. A controller for controlling an electrofusion joint, a power supply output setting means 11 for setting a power supply output value, a power supply output means 12 for supplying power according to the set value, and an information input means 13 for inputting pipe connection construction information And a data collection storage device 14 for storing the information input to the information input means 13. When the data collection storage device 14 is not ready for operation, the power supply output to the joint is reduced. in electro fusion fitting for controller ing comprises a interlock means 15 and not to allow the interlock means, When the storage medium over data collection storage device is not set, or the recording medium is set and when the storage capacity is insufficient state, having a means for interrupting the power supply output from the power supply output means It is characterized by that.
[0009]
By adopting this configuration, an EF joint controller capable of reliably recording and storing the construction information in the connection work of the plastic pipe using the EF joint is obtained.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a block diagram showing an EF joint controller 10 according to an embodiment of the present invention. In the figure, reference numeral 11 denotes power supply output setting means for setting a power supply output value of electric power to be supplied to the EF joint. Reference numeral 12 denotes an electric power supply output setting means connected to the power supply output setting means 11 and an EF joint according to an instruction of the power supply output setting means 11. Power supply output means for outputting a power supply output to the power supply. Reference numeral 13 denotes information input means for inputting construction information, and reference numeral 14 denotes a data collection recording device connected to the information input means 13 for recording construction information.
[0011]
Further, an interlock means 15 which is a feature of the present invention is inserted in the output wiring of the power supply output means 12. The interlock means 15 includes an AND circuit 16 for ANDing a signal corresponding to a plurality of pieces of information from the information input means 13 and a signal transmitted when the preparation of the data acquisition recording device 14 is completed. And a switch 17 for turning on / off the power supply output output from the power supply output means 12 by being driven by the power supply signal.
[0012]
As a means for inputting information to the information input means 13, a bar code, an ID card, a key input, a remote information source via a communication means, or the like is used. Therefore, the information input means 13 needs to include at least one of a bar code reader, a magnetic reader, a keyboard, a modem, etc., corresponding to the means for inputting information.
[0013]
Further, as the construction information to be input to the information input means 13, (1) construction manager information, and (2) information (construction company name, construction number, construction date and time, construction location, etc.) which clearly indicates the construction. These pieces of information may be input alone or in combination. Then, when these pieces of information are input, signals are respectively sent to the AND circuit 16.
[0014]
Further, a recording device using a floppy disk, a memory card, or the like as a recording medium is used as the recording device 14 for data collection. When these recording media are not set, or when the recording capacity of the recording medium is insufficient even if the recording medium is set, no signal is sent to the AND circuit 16. A signal is sent to the AND circuit 16 only when the recording medium is set and the storage capacity of the set recording medium is sufficient.
[0015]
The operation of the present embodiment thus configured will be described below. First, the output cable of the power supply output means 12 is connected to the EF joint. Next, the power supply output is set by the power supply output setting means 11 and output from the power supply output means 12. At this time, the switch 17 is off because there is no signal from the AND circuit 16. Therefore, the output from the power supply output means 12 is cut off by the switch 17 and power is not supplied to the EF joint.
[0016]
Next, when a predetermined number of construction information is input to the information input means 13, a signal corresponding to the input information is sent from the information input means 13 to the AND circuit 16. When a storage medium is set in the data collection storage device 14 and it is confirmed that the storage medium has sufficient capacity, a signal is sent from the data collection storage device 14 to the AND circuit 16 when the preparation is completed. . At the same time, the data collecting storage device 14 records the construction information input to the information input means 13.
[0017]
The AND circuit 16 sends a signal to the switch 17 to turn on the switch 17 when all of the signals from the information input means 13 and the data collection storage device 14 are collected. When the switch 17 is turned on, the power supply output from the power supply output means 12 is passed and output to the EF joint. As a result, the heating wire of the EF joint generates heat and melts the inner surface of the joint and the outer peripheral surface of the plastic pipe to be connected to perform connection.
