Abstract

<P>PROBLEM TO BE SOLVED: To easily and surely discriminate only a target cable among multiple cables, with less external bad effect applied to the cable. <P>SOLUTION: A string length body 15 comprises a long tape 25, a plurality of RFIDs23 spaced on one side of the tape 25 in the length direction, and a spacer 29 which is pasted near the RFID23 to protect the RFID23 from an external force, being thicker than the RFID23. Since the RFID23 is protected with the spacer 29 being thicker than the RFID23 neat it, the mechanical strength of the string length body 15 is improved. Even if an external force is applied on the string length body 15, the spacer 29 absorbs the external force to prevent damage on the RFID23. A cable attached with the string length body 15 vertically is easily discriminated by the RFID23. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

以上の表１から分かるように、比較例１の連長体６７は、６００回の衝撃を加えた後に，ＲＦＩＤ２３の情報を読みとれなくなった。すなわち耐衝撃回数は５００回であった。第１〜第４の実施の形態の連長体２１、５３、５７、６１は上限の２０００回を行っても情報が読みとれた。
【０１０９】
したがって、第１〜第４の実施の形態の連長体２１、５３、５７、６１のいずれにおいても、ＲＦＩＤ２３がスペーサ６５によって外力が吸収されて保護されていることが明らかである。
【０１１０】
〔比較試験２〕
さらに、上記の第１〜第４の実施の形態の連長体２１、５３、５７、６１をケーブルの内部又は表面に縦添えした光ファイバケーブル１の効果性を確認するために、第１の実施の形態の連長体２１を縦添えした図５の形態の光ファイバケーブル１を代表して製造し、上記の比較例１の連長体６７を図５の形態と同様にしてケーブルの内部に縦添えした光ファイバケーブルを比較例２として製造し、それぞれに対して比較試験を行った。
【０１１１】
ちなみに、試験方法は圧壊試験（ＪＩＳＣ６８２１準拠）に基づいたものであり、試験条件は、圧壊試験用鋼板１００ｍｍで、ＲＦＩＤ２３のあるケーブル面を上にして、ＲＦＩＤ２３の部分を狙って荷重を印可した。このときの印可時間１分である。なお、印可荷重は５Ｎ／ｍｍ刻みに増やすものである。そして、一回の試験ごとにＲＦＩＤ２３からの情報が読みとれるかを確認し、表２に示されているように情報が読みとれたときの最大の印可荷重が得られる試験値として確認された。
【０１１２】
【表２】

以上の表２から分かるように、比較例２の光ファイバケーブルでは、印可荷重が１０Ｎ／ｍｍのときに情報が読みとれなくなった。また、この実施の形態の光ファイバケーブルでは２０Ｎ／ｍｍのときに情報が読みとれなくなった。したがって、ケーブル状態においても、この発明のスペーサを使用した連長体の方が機械的特性に優れることは明らかである。
【０１１３】
次に、この発明の第５の実施の形態の連長体６９について詳しく説明する。なお、前述した第１の実施の形態の連長体２１と同様の部分の詳細な説明は省略する。
【０１１４】
図１１ないしは図１３を参照するに、連長体６９は、ＲＦＩＤ２３が長尺のテープ状の第１面状緩衝体７１の片面にその長手方向に適宜間隔を介して配列され、接着固定されている。この第５の実施の形態では一定間隔のピッチＰ、つまり１ｍピッチで配列されている。
【０１１５】
上記の第１面状緩衝体７１としては、材質が不織布で、厚さ１ｍｍで、幅３０ｍｍであり、第１面状緩衝体７１の片面には予め接着材層７３が設けられており、防水効果を持つ吸水性高分子としてポリアクリル酸塩が混ぜられている。
【０１１６】
さらに、上記のＲＦＩＤ２３を外力から保護するために、第２面状緩衝体７５がＲＦＩＤ２３を外側から覆うようにして第１面状緩衝体７１に貼り合わされている。上記の第２面状緩衝体７５は前述した第１面状緩衝体７１と同様の材質、厚さ、幅を有し且つ吸水性高分子としてポリアクリル酸塩が混ぜられている。また、第２面状緩衝体７５の片面には予め接着材層７７が付けられている。
【０１１７】
なお、上記の第１，第２面状緩衝体７１，７５は、縦添えされる光ファイバケーブル１の外皮１９より柔らかい材質であれば外力を吸収するという点で効果を得ることができる。したがって、十分に外皮１９より柔らかい材質にするために、紙、不織布、綿、布等を好んで用いることができる。また、柔らかいプラスチックも使用可能である。また、緩衝材としては、固体に限らず、ゲル状のものでＲＦＩＤ２３付近に封入させる形態であっても構わない。また、上記の第１，第２面状緩衝体７１，７５は、厚みがあるほど、得られる効果が大きい。
【０１１８】
また、第１，第２面状緩衝体７１，７５にデンプン、セルロース、ポリビニルアルコール、ポリアクリル酸塩などの吸水性高分子を包んだり、接着塗布したり、練り込んだりして、吸水性を高めたものも好んで使用される。
【０１１９】
この第５の実施の形態の連長体６９の作用は、ＲＦＩＤ２３の少なくとも片面に、ケーブル１の外皮１９と比べて硬度の小さい第１，第２面状緩衝体７１，７５が少なくともＲＦＩＤ２３を覆うようにして構成しているので、連長体６９に外力が加わることがあっても、上記の面第１，第２状緩衝体７１，７５が緩衝材となり、外力及び衝撃がＲＦＩＤ２３へ伝達するのを減少させ、ＲＦＩＤ２３の破損を防ぐことができる。また、第１，第２面状緩衝体７１，７５に防水効果を持つ吸水性高分子を混ぜることにより、ＲＦＩＤ２３中に浸水することを防ぐ効果もある。
【０１２０】
図１４を参照するに、この第５の実施の形態の連長体６９の製造方法としては、長尺の第１面状緩衝体７１の片面に付けた接着材層７３に、ＲＦＩＤ供給装置４９から直径２０ｍｍで、厚さ０．３５ｍｍのディスク状のＲＦＩＤ２３が上記の第１面状緩衝体７１の長手方向に一定間隔の１ｍピッチで供給され、第１面状緩衝体７１の片面の接着材層７３に貼着される。次いで、第２面状緩衝体７５がＲＦＩＤ２３を覆うようにして上記の第１面状緩衝体７１の片面に接着材層７３及び７７を介して貼り合わされ、加圧ローラ７９にて貼着され、連長体６９が製造される。
【０１２１】

【０１２４】
この第６の実施の形態の連長体８１の作用は、ＲＦＩＤ２３の少なくとも片面に、ケーブルの外皮１９と比べて硬度の小さい第２面状緩衝体７５が少なくともＲＦＩＤ２３を覆うようにして構成しているので、連長体８１に外力が加わることがあっても、上記の第２面状緩衝体７５が緩衝材となり、外力及び衝撃がＲＦＩＤ２３へ伝達するのを減少させ、ＲＦＩＤ２３の破損を防ぐことができる。また、第２面状緩衝体７５に吸水性高分子を混ぜているのでＲＦＩＤ２３中への浸水を防ぐ効果もある。
【０１２５】
この第６の実施の形態の連長体８１の製造方法としては、前述した第５の実施の形態の連長体６９の製造方法を示す図１４において、長尺の第１面状緩衝体７１が第１テープ体２５に替えただけで同様であるので、詳細な説明を省略する。
【０１２６】

【０１３８】
図２０を参照するに、連長体９１は、ＲＦＩＤ２３が長尺の第１テープ体２５の片面に、この第９の実施の形態では長手方向に一定間隔の１ｍピッチで配列され、接着固定されている。上記の第１テープ体２５は材質がＰＥＴで、厚さ３０μｍで、幅３０ｍｍであり、第１テープ体２５の片面には予め接着材層２７が設けられている。
【０１３９】

【０１５４】
また、長尺の第２テープ体３３が上記のゲル状物１０１の外側から覆うようにして裏面の接着材層７７を介して第１テープ体２５に貼り合わされている。なお、第２テープ体３３は材質、厚さ、幅が第１テープ体２５とほぼ同様である。
【０１５５】
この第１１の実施の形態の連長体９９の作用は、基本的には第５の実施の形態の連長体６９と同様であり、ゲル状物１０１または吸水性高分子の粉末がＲＦＩＤ２３に加わる外力及び衝撃を減少させ、ＲＦＩＤ２３の破損を防ぎ、ＲＦＩＤ２３中への浸水も防ぐ作用をする。
【０１５６】
図２５を参照するに、この第１１の実施の形態の連長体９９の製造方法としては、長尺の第１テープ体２５の片面に付けた接着材層２７に、ＲＦＩＤ供給装置４９からＲＦＩＤ２３が上記の第１テープ体２５の長手方向に一定間隔の１ｍピッチで供給され、第１テープ体２５の片面の接着材層２７に貼着される。次いで、ゲル状物供給装置１０３からゲル状物１０１が供給されＲＦＩＤ２３を封入する。その後、第２テープ体３３が上記のゲル状物１０１の外側から覆うようにして裏面の接着材層７７を介して第１テープ体２５に貼り合わされ、加圧ローラ７９にて貼着され、連長体９９が製造される。
【０１５７】
次に、上記の第５〜第１１の実施の形態の連長体６９，８１，８３，８９，９１，９７，９９が図５に示されている光ファイバケーブル１に使用されたときの効果性を確認するために、以下の比較試験を行った。
【０１５８】
〔比較試験３〕
まず、上記の第５〜第１１の実施の形態で使用された緩衝体と光ファイバケーブル１の外皮１９の硬度とを比較すると、表３のようになる。
【０１５９】
【表３】

表３に示されているように、各材料の硬度は、硬い方から、ＰＥＴ（１００）＞低密度ポリエチレン（９０）＞不織布（１０）＞ゲル状物（Ｏ）の順であった。硬度試験は、ＪＩＳ Ｋ６３０１に基づいて行った。ゲル状物は、ＪＩＳ Ｋ６３０１試験と同体積分の試料を用いて測定した。
【０１６０】
〔比較試験４〕
図５の光ファイバケーブルに基づいて、上記の第５〜第１１の実施の形態の連長体６９，８１，８３，８９，９１，９７，９９を使用したケーブルと、前述した比較例１の連長体６７を使用したケーブル（前述した比較例２のケーブル）と、ＲＦＩＤ２３の単体をケーブル長手方向に１ｍピッチの間隔で外皮１９の中に埋め込んだケーブル（比較例３）と、を比較する試験を行った。
【０１６１】
ちなみに、試験方法は圧壊試験（ＪＩＳ Ｃ６８２１準拠）に基づくものであり、試験条件は前述した比較試験２と同様である。その結果、表４に示されているように情報が読みとれたときの最大の印可荷重が得られる試験値として確認された。
【０１６２】
【表４】

以上の表４から分かるように、ＲＦＩＤ２３の単体をケーブル中に埋め込んだケーブルや、比較例１を使用したケーブルよりも、第５〜第１１の実施の形態の連長体（緩衝体を含むもの）を使用したケーブルの方が、ＲＦＩＤ２３が壊れて情報が読みとれなくなるまでの荷重が大きく、機械的特性に優れている。したがって、連長体の中に埋め込まれた面状緩衝体７５，８５やゲル状物１０１などの緩衝体が、ケーブル１の外皮１９よりも柔らかいために、ＲＦＩＤ２３にかかる外力の伝達を減少させている。
【０１６３】
〔比較試験５〕
上記の第１１の実施の形態の連長体９９と、第１１の実施の形態でゲル状物１０１の代わりに吸水性高分子（ポリアクリル酸塩）を用いた連長体と、前述した比較例１の連長体６７と、ＲＦＩＤ２３の単体との防水性を比較する防水性試験を行った。なお、試験方法はＩＥＣ５２９準拠したものであり、試験特性としてはＩＰの等級である。
【０１６４】
ちなみに、ＩＰ（Ｉｎｔｅｒｎａｔｉｏｎａｌ Ｐｒｏｔｅｃｔｉｏｎ）の各等級としては、次に示す通りである。ＩＰ６５級は、噴流水に対する構造であり、内径６．３ｍｍのノズルを用い、２９．４ｋＰａの水を３ｍの距離からあらゆる方向に１５分注水しても水が進入しない構造である。ＩＰ６６級は、波浪に対する構造であり、内径１２．５ｍｍのノズルを用い、９８ｋＰａの水を３ｍの距離からあらゆる方向に１分間注水しても水が進入しない構造である。ＩＰ６７級は、水中への浸漬に対する保護構造であり、水深１ｍに３０分間没しても水が進入しない構造である。
【０１６５】
【表５】

以上の表５から分かるように、ＲＦＩＤ２３の単体や、比較例１の連長体よりも、第１１の実施の形態の連長体９９の方が、防水グレードが高く、防水性に優れている。特に、ＲＦＩＤ２３を封入する封入緩衝物としては吸水性高分子の粉末よりもゲル状物１０１の方が防水性に優れている。したがって、封入緩衝物により連長体自体の防水性が向上するので、封入緩衝物を備えた連長体を縦添えしたケーブルが高湿環境下に置かれても、浸水によるＲＦＩＤの破壊が起こりにくくなるため、ＲＦＩＤの惰報が読みとれるケーブルとなる。
【０１６６】
なお、この発明は前述した実施の形態に限定されることなく、適宜な変更を行うことによりその他の態様で実施し得るものである。
【０１６７】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a continuous body provided with an RFID capable of easily identifying only a target cable from a large number of cables laid, a manufacturing method thereof, and an optical fiber cable using the continuous body About.
[0002]
[Prior art]
For example, a number of optical fiber cables are laid in the trough, and equipment rooms are provided at intervals of 2.5 to 5 km, and the above-mentioned many cables are connected to connection terminals of each equipment room. The management of each cable of the connection terminal and the removal of the cable are required to reliably identify each cable.
[0003]
As a conventional cable identification method, a method of performing identification printing on the outer surface of a cable, or attaching an identification tag to the end of each cable has been adopted. In the above-described identification print, cable information such as a manufacturer name / manufacturing date / cable product name / length is displayed on the cable surface by ink, thermal transfer, laser, or the like. In the case of the identification tag, for example, the cable information of the above-described items is engraved on a thin metal plate and attached to each cable, or is suspended by a metal wire or the like (for example, see Patent Document 1).
[0004]
As another cable identification method, a QR code printing paper in which the installation related information of the optical cable is converted into a two-dimensional QR code and printed is attached to the outer cover of the optical cable. At the time of maintenance or the like, the recorded information is read out at the installation site by scanning the QR code printed paper with a code reader. The information of the optical cable is similarly read from the above-described QR code printing paper in place of the bar code, the magnetic card, and the IC card (for example, see Patent Document 2).

[0007]
[Problems to be solved by the invention]
By the way, in the conventional cable identification method, when the identification printing is performed on the cable surface, the printing is performed in the longitudinal direction of the cable. There was a problem that it could not be confirmed unless it was exposed. Removal of long sections of trough lids and soil will increase construction costs. For this reason, the entire length of the identification print is desirably 1 m or less, but the number of characters that can be printed to about 1 m is limited, so that it is impossible to describe all necessary information. .
[0008]
In addition, in the identification printing, characters may disappear when a long period of time elapses or is rubbed.
[0009]
In addition, in the case of the method of attaching the identification tag, since it is necessary to attach the tag to a long cable at a constant interval, there is a problem that the number of the tag becomes enormous and the construction cost is increased.
[0010]
Further, the number of characters that can be written in the identification tag is limited, and it is impossible to describe all necessary information. In addition, characters are written on the identification tag by engraving or the like, but there is a problem that the characters may be blurred after a long period of time, as in the case of the identification printing, and may not be distinguished.
[0011]
In addition, when a QR code printing paper, a bar code, a magnetic card, an IC card, or the like is stuck on the outer cover of the optical cable, the writing information is small, and it becomes indistinguishable after a long period of time or rubbing. There is a problem that this occurs.
[0012]
The identification of cables is necessary to determine the target cable from a large number of cables at the time of re-laying or spreading work. However, the identification printing, identification tag, QR code printing paper, and barcode are unclear. Or when there are a plurality of cables having the same display, there is a problem that it takes much time to determine the information.
[0013]
Furthermore, if the wrong cable is disconnected, the device controlled by the signal flowing through the cable may malfunction or stop the information, resulting in a serious accident. .

[0105]
Next, a comparison was made to confirm the effectiveness when the continuous bodies 21, 53, 57, and 61 of the first to fourth embodiments were used for the optical fiber cable 1 shown in FIG. The continuous body 67 of Example 1 was manufactured, and the following comparative test was performed.
[0106]
Referring to FIG. 10, as the continuous body 67 of Comparative Example 1, the first tape body 25, the second tape body 33, the RFID 23, and the arrangement state of the RFID 23 are the same as those of the first to fourth embodiments. This is the same as the continuous bodies 21, 53, 57, and 61, except that the first tape body 25 and the second tape body 33 are bonded together without spacers.
[0107]
[Comparative test 1]
Impact resistance tests were performed on the elongated bodies 21, 53, 57, and 61 of the first to fourth embodiments and the elongated body 67 of Comparative Example 1, respectively. Incidentally, the impact test method was performed based on an impact test ("IEC68-2-27 (1987): Basic environmental testing procedures Part 2.1: Tests Test Ea: Shock"). The test conditions are such that a load of 40 g is applied to the RFID 23 in one direction from directly above the RFID 23 at a speed of 18 msec. As for the number of tests, the test is performed 100 times, and the operation is confirmed every 100 times. If the information can be read, the test is continued. As a result, as shown in Table 1, the maximum number of times the information was read was confirmed. The upper limit of the test was 2000 times.
[0108]
[Table 1]

As can be seen from Table 1 above, the run 67 in Comparative Example 1 could not read the information of the RFID 23 after the application of 600 shocks. That is, the number of times of impact resistance was 500 times. In the runners 21, 53, 57, and 61 of the first to fourth embodiments, information was read even after the upper limit of 2,000 times was performed.
[0109]
Therefore, in any of the elongated members 21, 53, 57, and 61 of the first to fourth embodiments, it is clear that the RFID 23 is protected by the external force absorbed by the spacer 65.
[0110]
[Comparative test 2]
Further, in order to confirm the effectiveness of the optical fiber cable 1 in which the elongated bodies 21, 53, 57, and 61 of the above-described first to fourth embodiments are vertically attached to the inside or the surface of the cable, the first The optical fiber cable 1 of the embodiment of FIG. 5 to which the elongated body 21 of the embodiment is longitudinally attached is manufactured as a representative, and the elongated body 67 of the comparative example 1 is formed inside the cable in the same manner as in the embodiment of FIG. Were manufactured as Comparative Example 2 and a comparative test was performed on each of them.
[0111]
Incidentally, the test method was based on a crush test (based on JIS C6821). The test condition was a steel plate for crush test 100 mm, a load was applied to the RFID 23 portion with the cable surface with the RFID 23 facing upward. The application time at this time is one minute. Note that the applied load is increased in steps of 5 N / mm. Then, it was confirmed whether or not the information from the RFID 23 could be read for each test, and as shown in Table 2, it was confirmed as a test value at which the maximum applicable load when the information was read was obtained.
[0112]
[Table 2]

As can be seen from Table 2 above, with the optical fiber cable of Comparative Example 2, information could not be read when the applied load was 10 N / mm. In the optical fiber cable of this embodiment, information could not be read at 20 N / mm. Therefore, it is clear that the continuous body using the spacer of the present invention has better mechanical properties even in the cable state.
[0113]
Next, a continuous body 69 according to a fifth embodiment of the present invention will be described in detail. The detailed description of the same parts as those of the elongated body 21 of the first embodiment is omitted.

The second planar buffer 75 has the same material, thickness and width as the first planar buffer 71 described above, and is mixed with polyacrylate as a water-absorbing polymer. An adhesive layer 77 is previously attached to one surface of the second planar buffer 75.
[0117]
The first and second planar buffers 71 and 75 can be made of a material that is softer than the outer sheath 19 of the vertically attached optical fiber cable 1 to obtain an effect of absorbing external force. Therefore, in order to make the material sufficiently softer than the outer cover 19, paper, nonwoven fabric, cotton, cloth, or the like can be preferably used. Also, soft plastics can be used. The cushioning material is not limited to a solid, but may be a gel-like material that is sealed in the vicinity of the RFID 23. The greater the thickness of the first and second planar buffers 71 and 75, the greater the effect obtained.
[0118]
In addition, the first and second planar buffers 71 and 75 are wrapped with a water-absorbing polymer such as starch, cellulose, polyvinyl alcohol, and polyacrylate, or are coated with adhesive or kneaded to reduce water absorption. Enhanced ones are also preferred.
[0119]

With such a configuration, even if an external force is applied to the elongated body 69, the surface first and second cushions 71 and 75 serve as cushioning materials, and the external force and impact are transmitted to the RFID 23. And the damage of the RFID 23 can be prevented. Further, by mixing the first and second planar buffers 71 and 75 with a water-absorbing polymer having a waterproof effect, there is also an effect of preventing the RFID 23 from being immersed in water.
[0120]
Referring to FIG. 14, as a method of manufacturing the continuous body 69 of the fifth embodiment, an RFID supply device 49 is attached to an adhesive layer 73 attached to one surface of a long first planar buffer 71.

[0158]
[Comparative test 3]
First, Table 3 shows a comparison between the hardness of the outer cover 19 of the optical fiber cable 1 and the buffer used in the fifth to eleventh embodiments.
[0159]
[Table 3]

As shown in Table 3, the hardness of each material was in the order of PET (100)> low-density polyethylene (90)> nonwoven fabric (10)> gel (O) from the harder one. The hardness test was performed based on JIS K6301. The gel was measured using a sample of the same volume as in the JIS K6301 test.
[0160]
[Comparative test 4]
Based on the optical fiber cable of FIG. 5, a cable using the elongated bodies 69, 81, 83, 89, 91, 97, and 99 of the fifth to eleventh embodiments described above and the cable of Comparative Example 1 described above. A cable using the elongated body 67 (the cable of the comparative example 2 described above) is compared with a cable (Comparative Example 3) in which the RFID 23 alone is embedded in the outer cover 19 at a pitch of 1 m in the longitudinal direction of the cable. The test was performed.
[0161]
Incidentally, the test method is based on a crush test (based on JIS C6821), and the test conditions are the same as those in Comparative Test 2 described above. As a result, as shown in Table 4, it was confirmed as a test value at which a maximum applied load when information was read was obtained.
[0162]
[Table 4]

As can be seen from Table 4 above, the continuous body (including the buffer) according to the fifth to eleventh embodiments is better than the cable in which the RFID 23 alone is embedded in the cable or the cable using Comparative Example 1. The cable using ()) has a larger load until the RFID 23 is broken and information cannot be read, and is superior in mechanical properties. Accordingly, since the buffer members such as the planar buffer members 75 and 85 and the gel material 101 embedded in the continuous body are softer than the outer cover 19 of the cable 1, the transmission of the external force applied to the RFID 23 is reduced. I have.

[Comparative test 5]
The comparison between the elongated body 99 according to the eleventh embodiment and the elongated body using a water-absorbing polymer (polyacrylate) instead of the gel-like material 101 according to the eleventh embodiment described above. A waterproofness test was performed to compare the waterproofness of the continuous body 67 of Example 1 with the RFID 23 alone. The test method is based on IEC529, and the test characteristics are IP grade.
[0164]
Incidentally, each grade of the IP (International Protection) is as follows. The IP65 class is a structure for jet water, and has a structure in which water of 29.4 kPa does not enter even when water of 29.4 kPa is injected from a distance of 3 m in all directions for 15 minutes using a nozzle having an inner diameter of 6.3 mm. The IP66 class is a structure against waves, and uses a nozzle having an inner diameter of 12.5 mm, and has a structure in which water does not enter even if 98 kPa of water is injected for 1 minute in all directions from a distance of 3 m from a distance of 3 m. The IP67 class is a protection structure against immersion in water, and is a structure in which water does not enter even if immersed at a depth of 1 m for 30 minutes.
[0165]
[Table 5]

As can be seen from Table 5 described above, the continuous body 99 of the eleventh embodiment has a higher waterproof grade and is more excellent in waterproofness than the simple substance of the RFID 23 or the continuous body of Comparative Example 1. . In particular, as an encapsulating buffer for enclosing the RFID 23, the gel-like material 101 is more waterproof than the water-absorbing polymer powder. Accordingly, the sealing buffer enhances the waterproofness of the runner itself, so that even if the cable with the runner equipped with the sealant buffer is placed in a high-humidity environment, the destruction of the RFID due to inundation may occur Since it becomes difficult, it becomes a cable from which RFID coast information can be read.
