Description

【０００１】
【発明が属する技術分野】
本発明は、樹脂管との接合面に電熱線を埋設した電気融着継手と樹脂管との電気融着方法及び装置に関する。
【０００２】
【従来技術】
電気融着装置として、特開平９−２４２９６９号には、電気融着継手に取付けた外部識別情報（バーコード）を読み取る外部識別情報読取手段（バーコードリーダ）と、過去に使用された電気融着継手の継手番号を記憶する記憶部と、外部情報読取手段で読み取った外部識別情報のなかの継手番号と記憶部に記憶された継手番号を照合し、同一番号のものがあるか否かによって融着の可不可を判定する演算制御部を有するコントローラが提案されている。
【０００３】
【発明が解決しようとする課題】
上記コントローラによると、記憶部に記憶される融着履歴のなかに同じ継手番号があると、融着が行えないため、事実上、同じ継手に対し、融着を二度行うことが不可能となり、同じ継手に融着を二回行う、といった施工ミスや不正行為を避けることができるが、例えば継手開発時や工務店が施工手順を習熟するために同じ継手に融着を複数回繰り返すことが必要となることがある。こうした場合には、継手番号を変えた外部識別情報を別に用意し、この情報を読み取って融着を行わねばならないが、使い勝手が悪いうえ、一度使用した継手番号は当該コントローラでは使えないため、外部識別情報に継手番号を設定する際には、記憶部に記憶された継手番号を読み出して、それ以外の継手番号を選択して設定せねばならず、面倒である。
【０００４】
本発明は、上記の問題を解消し、必要によっては融着を複数回、簡易に繰返し行うことができるようにした電気融着方法及び装置を提供することを目的とする。
【０００５】
【課題の解決手段】
請求項１に係わる発明は、外部入力手段を用いて電気融着継手の継手番号を入力するステップと、外部入力手段により入力された継手番号をコントローラの記憶部に記憶された、過去に使用された電気融着継手の継手番号と照合するステップと、外部入力手段により入力された継手番号が記憶部に記憶された継手番号と重複しないときに融着可とするステップとを有する電気融着方法において、電気融着継手の継手番号が記憶される上記記憶部又は該記憶部とは別の記憶部にパスワードを予め記憶しておき、外部入力手段からパスワードが入力されたとき、このパスワードを上記記憶部に記憶されたパスワードと照合するステップと、パスワードが一致すると、その都度、融着の前歴の如何にかかわらず融着可とするステップを有することを特徴とする。
【０００６】
本発明によると、外部入力手段からパスワードが入力されると、その都度融着が可能となり、パスワードを繰返し入力すると、同じ継手に対し、何度でも融着が可能となる。
【０００７】

【０００８】
本発明におけるパスワードとは、２回以上の電気融着を可とするためのいわば「合言葉」であって、少なくとも継手への通電作業を行う以前の段階で定められた固有の情報のことである。具体的には、文字、図形、記号等を用いることができ、また条件式を用いることもできる。この場合、コントローラは、外部入力手段から入力された条件が条件式を満たすと判断すると、パスワードと認識する。
【０００９】
請求項２に係わる発明は、電気融着継手に取付けた外部識別情報を読み取る外部識別情報読取手段と、過去に使用された電気融着継手の継手番号を記憶する記憶部と、外部識別情報読取手段で読み取った外部識別情報のなかの継手番号と、記憶部に記憶された継手番号を照合し、読み取った継手番号が記憶された継手番号のなかにあるか否かを検索する検索部と、検索部の検索結果に基づいて融着の可不可を判定する判定部とを有する、電気融着継手と樹脂管とを電気融着する際に用いる電気融着装置において、電気融着継手の継手番号を記憶する上記記憶部又は該記憶部とは別の記憶部にパスワードが記憶され、上記外部識別情報読取手段が外部識別情報に書き込まれたパスワードを読み取り、読み取ったパスワードが上記記憶部に記憶される上記パスワードと一致すると、その都度、上記判定部が上記検索部の検索結果の如何にかかわらず融着可と判定することを特徴とする。
【００１０】
本発明によると、外部識別情報読取手段が外部識別情報からパスワードを読み取ると、その都度融着が可能となり、同じ継手に対し何度でも融着が可能となる。
【００１１】
本発明における外部識別情報としては、例えばバーコード、磁気テープ、バンド、ディスク等の磁気記録体等を例示することができ、外部識別情報読取手段としては、例えばバーコードを読み取るバーコードリーダ、磁気記録体を読み取る磁気センサー等を例示することができる。

【発明の実施の形態】
図１は、電気融着ソケット継手１と樹脂管２とを電気融着装置としてのコントローラ３を用いて電気融着するときのシステムの概要を示すもので、電気融着ソケット継手１には内周面にターミナルピン１ａに繋がる電熱線１ｂがコイル状にして埋設され、表面には外部識別情報としてのバーコードを付したバーコードラベル４が取付けられている。このバーコードラベル４は、継手１が小さく継手１に取付けられない場合、継手１に連結したプレートに取付けられる。
バーコードラベル４のバーコードには、継手のメーカ名、継手の種類や口径、継手番号、通電時の標準電流、電圧、通電時間等が記録されている。
【００１５】
コントローラ３は、電源（図示しない）に差し込まれる差込プラグ５と、バーコードを読み取る外部識別情報読取手段としてのバーコードリーダ６を有し、かつ内部に電源から継手1の電熱線１ｂに電気エネルギーを供給する回路に設けられ、該回路を開閉するスイッチ手段を含む電源制御部７と、記憶部８と、検索部９と、電源制御部７を制御する制御部１１を有している。このうち、記憶部８は過去に融着した融着履歴を記憶するメモリー部を有し、このメモリー部のなかに融着履歴の一つである継手番号を記憶するメモリー域を備えている。
【００１６】
検索部９は、バーコードリーダ６で読み取った継手情報のなかの継手番号を記憶部８の上記メモリー域に記憶される継手番号と照合し、読み取った継手番号が融着履歴の継手番号のなかにあるか否かを検索する機能を有しており、制御部１１は検索部９の検索結果に基づいて融着の可否を決定する機能、すなわち読み取った継手番号が融着履歴の継手番号のなかにあるときは融着不可、ないときには融着可の決定を行う判定部としての機能と、電源制御部７を制御し、融着可のときは当該継手番号を記憶部８に記憶させると共に、電源制御部７のスイッチ手段をＯＮにする機能を有し、スイッチ手段をＯＮにすることにより通電が開始されるようになっている。
【００１７】
次に、本発明の電気融着装置における動作の一態様を図２により説明する。
まず、バーコードリーダ６により電気融着ソケット継手１に貼付されたバーコードラベルのバーコードから融着条件等を読み取る（ｓ１）。すると、このデータが制御部１１に送られ、制御部１１はこのデータより継手１の継手番号を抽出して検索部９に出力する。検索部９はこれにより記憶部８に記憶された、過去に融着した融着履歴のデータから当該継手番号を検索し（ｓ２）、照合する（ｓ３）。融着履歴中に当該継手番号が無い場合、該継手番号が記憶部８の融着履歴に加えて格納される（ｓ９）と共に、制御部１１が電源制御部７に制御信号を出力し、電気融着が行なわれる（ｓ１０）。融着履歴中に当該番号がある場合は、パスワードが入力されない限り（ｓ５）電気融着否とされ（ｓ１１）、電気融着は行われないが、パスワード、例えば〔９９９９〕という継手番号のパスワードがバーコードリーダ６やキーボード１４等その他の入力手段により入力されると（ｓ５）、検索部９が当該パスワードを記憶部８に記憶されたパスワード（ｓ７）から検索し（ｓ６）、照合する（ｓ７）。そして記憶部９に記憶されたデータのパスワード中に、当該パスワードが有れば、制御部７が電源制御部７のスイッチ手段に出力して電気融着が行なわれる（ｓ１０）。また、入力されたパスワードが誤っていて該当番号がないときには、電気融着否（ｓ１１）とされ、電気融着は行なわれない。
【００１８】
上記実施形態において、パスワードは記憶部８の継手番号を記憶するメモリー域に記憶されていてもよいし、継手番号を記憶するメモリー域とは別のメモリー域に記憶されていてもよい。また制御部のなかに記憶しておくこともできる。この場合、パスワードが入力されると、その照合は制御部で行われ、パスワードと認識すると、検索部による検索結果の如何にかかわらず、融着可と認定する。
パスワードはまた、記憶部に格納される条件式で、入力された条件が条件式をみたすと、制御部７がパスワードと判定し、融着が行われるようにしていてもよい。
【００１９】
図３に示す実施形態では、キーボード１４が設けられ、パスワードがキーボード１４から制御部１１に入力される。
本実施形態の場合、既存のバーコードを取付けた継手に対しても、キーボード１４からパスワードを入力することにより融着を複数回繰返し行うことが可能となる。
【００２０】
【発明の効果】
本発明によると、外部識別情報の中にパスワードを記録させておくことにより、同じ継手に対して何度でも繰返し融着を行うことができる。
またパスワードを入力手段から入力させるようにすることにより、外部識別情報の中にパスワードを記録させておかなくても融着を繰返し行うことができる。

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an outline of a system when an electric fusion socket joint 1 and a resin pipe 2 are electrically fused using a controller 3 as an electric fusion apparatus. A heating wire 1b connected to the terminal pin 1a is embedded in a coil shape on the peripheral surface, and a barcode label 4 with a barcode as external identification information is attached to the surface. The bar code label 4 is attached to a plate connected to the joint 1 when the joint 1 is small and cannot be attached to the joint 1.
On the barcode of the barcode label 4, the manufacturer name of the joint, the joint type and diameter, the joint number, the standard current during energization, the voltage, the energization time, and the like are recorded.
[0015]
The controller 3 has an insertion plug 5 to be plugged into a power source (not shown) and a bar code reader 6 as an external identification information reading means for reading the bar code, and is electrically connected from the power source to the heating wire 1b of the joint 1. A power supply control unit 7 including a switch unit that opens and closes the circuit, a storage unit 8, a search unit 9, and a control unit 11 that controls the power supply control unit 7 are provided in a circuit that supplies energy. Among these, the memory | storage part 8 has a memory part which memorize | stores the melt | fusion history fuse | melted in the past, and is provided with the memory area which memorize | stores the joint number which is one of the melt | fusion history in this memory part.
[0016]
The search unit 9 compares the joint number in the joint information read by the barcode reader 6 with the joint number stored in the memory area of the storage unit 8, and the read joint number is the joint number in the fusion history. The control unit 11 has a function of determining whether or not fusion is possible based on the search result of the search unit 9, that is, the read joint number is the joint number of the fusion history. When there is any, it is impossible to fuse, and when there is not, the function as a determination unit that determines whether or not fusion is possible, and the power supply control unit 7 are controlled, and when the fusion is possible, the joint number is stored in the storage unit 8 The power supply control unit 7 has a function of turning on the switch means, and energization is started by turning on the switch means.
[0017]
Next, one mode of operation in the electrofusion apparatus of the present invention will be described with reference to FIG.
First, the fusion conditions and the like are read from the barcode of the barcode label affixed to the electric fusion socket joint 1 by the barcode reader 6 (s1). Then, this data is sent to the control unit 11, and the control unit 11 extracts the joint number of the joint 1 from this data and outputs it to the search unit 9. Thus, the search unit 9 searches the joint number from the past fusion data stored in the storage unit 8 (s2) and collates (s3). If there is no joint number in the fusion history, the joint number is stored in addition to the fusion history in the storage unit 8 (s9), and the control unit 11 outputs a control signal to the power supply control unit 7 to Fusion is performed (s10). If the number is present in the fusion history, unless the password is input (s5), the electric fusion is rejected (s11), and the electric fusion is not performed, but the password, for example, the password of the joint number [9999]. Is input by other input means such as the barcode reader 6 or the keyboard 14 (s5), the search unit 9 searches the password (s7) stored in the storage unit 8 (s6) and collates ( s7). If the password of the data stored in the storage unit 9 is present, the control unit 7 outputs it to the switch means of the power supply control unit 7 to perform electrofusion (s10). If the input password is incorrect and there is no corresponding number, it is determined that the electric fusion is rejected (s11), and the electric fusion is not performed.

In the said embodiment, the password may be memorize | stored in the memory area which memorize | stores the joint number of the memory | storage part 8, and may be memorize | stored in the memory area different from the memory area which memorize | stores a joint number. It can also be stored in the control unit. In this case, when the password is input, the verification is performed by the control unit. When the password is recognized, it is determined that the fusion is possible regardless of the search result by the search unit.
The password may be a conditional expression stored in the storage unit. When the input condition satisfies the conditional expression, the control unit 7 may determine that the password is used, and fusion may be performed.
[0019]
In the embodiment shown in FIG. 3, a keyboard 14 is provided, and a password is input from the keyboard 14 to the control unit 11.
In the case of the present embodiment, it is possible to repeat the fusion several times by inputting a password from the keyboard 14 even for a joint to which an existing barcode is attached.
[0020]
【The invention's effect】
According to the present invention, the password can be recorded in the external identification information, so that the same joint can be repeatedly and repeatedly welded.
Further, by inputting the password from the input means, it is possible to repeatedly perform the fusion without recording the password in the external identification information.
