Abstract
Description
本発明は、熱可塑性樹脂管を接続するのに用いられる電気融着継手に関する。 The present invention relates to an electrofusion joint used for connecting thermoplastic resin pipes.
電気融着継手と樹脂管との電気融着は、通常電気融着継手と樹脂管をクランプして固定したのち、コネクターを継手のターミナルに差込み、電源から継手に付与される電気エネルギーを設定してコントローラが設定の電気エネルギー量が付与されるように制御している。 For electric fusion between an electric fusion joint and a resin pipe, usually the electric fusion joint and the resin pipe are clamped and fixed, and then the connector is inserted into the joint terminal to set the electrical energy applied to the joint from the power source. The controller controls so that the set amount of electric energy is applied.
電気エネルギー量の設定のため以前は、ターミナル部分に埋め込んだ抵抗体の抵抗を読取ることにより継手の種類を識別し、継手の種類ごとに予めコントローラに登録しておいた、通電時間、継手の電熱線に印加される電圧値等の融着情報の中から、当該継手の融着情報を求めていたが、近年では継手の融着情報はバーコードに記録され、バーコードの記録情報を読み取ることにより継手への電気エネルギー量を求めている。特許文献１には、その一例が示されている。 In order to set the amount of electrical energy, the type of joint was previously identified by reading the resistance of the resistor embedded in the terminal part, and the energization time and joint power previously registered in the controller for each type of joint. The fusion information of the joint has been sought from the fusion information such as the voltage value applied to the heat ray. In recent years, the fusion information of the joint has been recorded on the barcode, and the recorded information on the barcode has been read. The amount of electrical energy to the joint is obtained by Patent Document 1 shows an example thereof.
バーコードからは、通電時間や電圧値等の融着情報を直接読取ることが可能であり、しかもバーコードには上述する融着情報のほか、継手の種類や口径、シリアル番号等の継手情報、製造年月日やメーカ名等の製造情報を記載することができ、前記抵抗体に比べ、数多くの情報を記載することが可能である。 From the bar code, it is possible to directly read the fusion information such as energization time and voltage value, and besides the above-mentioned fusion information, the bar code includes joint information such as the joint type, diameter and serial number, Manufacturing information such as a manufacturing date and a manufacturer name can be described, and more information can be described as compared with the resistor.
一方、コントローラには、バーコードから読取った前述の融着情報、継手情報、製造情報のほか、施工した作業者のＩＤ、施工番号、ＧＰＳによる施工位置の情報、施工日時等の入力情報が記録され、また融着時の融着時間や電圧などの融着結果情報が記録されるようになっており、事務所に帰ったとき、その日に完了した施工情報、或いは一定期間内の施工情報がパソコンに転送して格納され、履歴追跡が行えるようにしている。 On the other hand, in addition to the above-mentioned fusion information, joint information, and manufacturing information read from the barcode, the controller records the input information such as the construction worker ID, construction number, construction position information by GPS, construction date and time, etc. Also, the fusion result information such as the fusion time and voltage at the time of fusion is recorded, and when returning to the office, construction information completed on that day, or construction information within a certain period of time It is transferred to a personal computer and stored so that history tracking can be performed.
融着時において、コントローラは継手から得られた前記継手情報と、コントローラに記録される融着済みの継手情報を照合し、融着済みの継手に誤って通電が行われることがないようにしている（同じ継手に通電が繰返されると、樹脂の劣化を生じがちとなる）。 At the time of fusion, the controller collates the joint information obtained from the joint with the joint information that has already been fused recorded in the controller so that the fused joint is not accidentally energized. (If the same joint is repeatedly energized, the resin tends to deteriorate).
バーコードから融着情報を読み取って電気融着継手と樹脂管との電気融着を行う従来法においては、バーコード読取り用のスキャナーと、該スキャナーによる読取り作業が必要である。
またパソコンから融着履歴を追跡するには、施工番号や施工日などの施工情報をインデックスとして検索する必要があり、現場で施工した継手からは得ることができない。
In the conventional method in which the fusion information is read from the barcode and the electric fusion joint and the resin pipe are electrically fused, a barcode reading scanner and a reading operation by the scanner are required.
Further, in order to track the fusion history from a personal computer, it is necessary to search for construction information such as a construction number and a construction date as an index, which cannot be obtained from a joint constructed on site.
本発明の第１の目的は、融着作業がより作業性よく、簡易に行えるような電気融着継手を提供しようとするものであり、第２の目的は、第１の目的に加え、施工した電気融着継手から直接、当該継手の履歴追跡が行えるような電気融着継手を提供しようとするものである。 The first object of the present invention is to provide an electric fusion joint that can perform fusion work more easily and easily, and the second object is construction in addition to the first object. It is an object of the present invention to provide an electric fusion joint that allows the history of the joint to be tracked directly from the electric fusion joint.
請求項１に係わる発明は、第１の目的を達成する電気融着継手に関するもので、通電時間を含む融着情報と、継手の種類や口径の継手情報と、継手の製造年月日やメーカ名の製造情報等の各種情報のうち、少なくとも上記融着情報が記録されるＩＣタグを備えていることを特徴とし、
請求項２に係わる発明は、第２の目的を達成する電気融着継手に関するもので、請求項１に係わる発明の電気融着継手において、ＩＣタグが読み書き可能なＩＣタグであり、該ＩＣタグに施工した作業者のＩＤ、施工番号、ＧＰＳによる施工位置、施工日時等の施工情報、融着時の融着時間や電圧などの融着結果情報のうちの一部若しくは全部の情報が書き込まれることを特徴とする。
The invention according to claim 1 relates to an electric fusion joint that achieves the first object, and includes fusion information including energization time, joint type and joint information, joint manufacture date and manufacturer. Among various types of information such as manufacturing information of the name, it is provided with an IC tag in which at least the fusion information is recorded,
The invention according to claim 2 relates to an electric fusion joint that achieves the second object. In the electric fusion joint according to claim 1, the IC tag is an readable / writable IC tag, and the IC tag Information on part or all of the ID, the construction number, the construction position by GPS, construction information such as construction date and time, and the fusion result information such as the fusion time and voltage at the time of fusion are written. It is characterized by that.
請求項１に係わる発明によると、ＩＣタグはバーコード以上に多量の情報量を登載することができること、ＩＣタグはリーダーから６０ｃｍ程度離れていても記録情報を非接触で読み取ることができるため、大抵の継手においては、ＩＣタグが継手のどのような箇所に取付けられていてもリーダーをコントローラのコネクターに取付けておけば、コネクターを電気融着継手のターミナルに差込むだけでＩＣタグに記録される、電気融着に必要な融着情報を自動的に読取ることができ、従来法のようにコネクターのターミナルへの差込み作業とは別にバーコードの読み取り作業を必要としていたのに比べ、バーコードの読み取り作業を必要としない分、融着作業を能率よく簡易に行うことができること等の効果を有する。 According to the invention according to claim 1, the IC tag can carry a larger amount of information than the barcode, and the IC tag can read the recorded information in a non-contact manner even if it is separated from the reader by about 60 cm. For most joints, if the reader is attached to the connector of the controller no matter where the IC tag is attached, it is recorded on the IC tag simply by inserting the connector into the terminal of the electrofusion joint. Compared to the bar code reading work that is required separately from the insertion work of the connector into the terminal as in the conventional method, the bar code information can be read automatically. Since there is no need for the reading operation, it is possible to perform the fusion work efficiently and easily.
また請求項２に係わる発明のように、ＩＣタグに読み書きが可能なＩＣタグを用いると、更に、
（１）コントローラに記録される継手の種類やサイズ、シリアル番号等の継手情報、継手の製造年月日やメーカ名等の製造情報、作業者のＩＤ、施工番号、ＧＰＳによる施工位置、施工日時、電気融着時における通電時間、電圧等の融着結果情報等の各種情報のうちの一部又は全部をＩＣタグに自動的に転記できること、
（２）ＩＣタグには上述するように継手情報、製造情報、施工情報、融着結果情報等の各種情報のうちの一部又は全部が記録されるが、これらの情報は施工された継手のＩＣタグから読み取って履歴追跡ができること、
（３）配管が地中に埋設されていても、埋設箇所が浅かったり、壁の向かい側或いは天井裏に行われていると、地面を掘削したり、壁や天井を壊したりすることなく、ＩＣタグに記録される情報を読み取り、継手に関する前記情報を得ることができること、
（４）配管が地中奥深く或いはコンクリート中に埋設されていたり、スペースが狭く或いは安全上、配管に近付くことができなくて、ＩＣタグの読取りができないような箇所にあっても、管内にリーダーを通すことにより、或いは管内点検のため、管内に通されるカメラにリーダーを組み付けることにより継手に関する前述の情報を得ることができること、
（５）従来の融着方法では、融着済みの同じ継手に対する通電の繰返し防止は、コントローラが継手のターミナル部分に埋め込んだ抵抗やバーコードから継手情報を読込み、コントローラに記録される融着済みの継手情報と照合することによって行っていたが、一度目の通電時に使用したコントローラと同じコントローラを使用しないと、通電の繰返し防止を行うことができない。この点、ＩＣタグに融着結果情報を書き込んでおくと、コントローラを変えてもＩＣタグの融着結果情報を読取ることにより通電の繰返しを避けることができること、
（６）前記と逆に樹脂管との融着を確実に行うため、電気融着を繰り返したい場合、従来のバーコードによるシステムでは、コントローラを変えることで電気融着の繰り返しが可能であるが、ＩＣタグでは完了フラグを書き込んで、新たな融着記録情報を記録できるようにすることにより、或いは施工日をフラグとし、異なった日に施工することにより電気融着を繰返すことが可能であること、
（７）ＩＣタグの継手への取付けは、例えば埋設、接着、止着、嵌着、ファイバーによる連結等によって行われるが、継手に直接取付けるのではなく、継手に取付けられるバーコードラベルに取付けてもよい。またＩＣタグ自体にバーコードを印刷してもよい。バーコードを印刷する場合、ＩＣタグは全体が埋設されず、少なくとも一面が継手より露出される。ＩＣタグとバーコードを併用することにより、継手の融着情報をバーコートの読み取りでも、ＩＣタグの読み取りでも得ることができ、従来法や他社システムとの併用が可能になり、システム切換時の互換性を確保することもできること、
等の効果を有する。

In this regard, if the fusion result information is written in the IC tag, it is possible to avoid repeated energization by reading the fusion result information of the IC tag even if the controller is changed.
(6) Contrary to the above, in order to perform the fusion with the resin tube reliably, when it is desired to repeat the electric fusion, the conventional bar code system can repeat the electric fusion by changing the controller. In the IC tag, it is possible to repeat the electric fusion by writing a completion flag so that new fusion record information can be recorded, or by using the construction date as a flag and performing construction on different days. thing,
