Description

ＩＣタグの取付構造IC tag mounting structure
　本発明は、工具ホルダに取付けられるＩＣタグの取付構造に関する。 The present invention relates to an IC tag mounting structure that is mounted on a tool holder.
　ＩＣタグは、対象物の認識媒体として利用される。例えば、工作機械等に用いられる工具ホルダにおいても、工具ホルダを識別するためにＩＣタグが取り付けられる。工具ホルダに取付けられるＩＣタグは、内部にメモリを有するＩＣチップと、アンテナとなるコイルとで構成され、合成樹脂で一体的にモールド成形されている。 IC tag is used as an object recognition medium. For example, in a tool holder used for a machine tool or the like, an IC tag is attached to identify the tool holder. The IC tag attached to the tool holder includes an IC chip having a memory inside and a coil serving as an antenna, and is integrally molded with a synthetic resin.
　こうしたＩＣタグは、外部のライタ装置からの電波を受けて工具ホルダに関するデータをＩＣチップに格納するとともに、外部のリーダ装置を近接させることで格納されたデータを読み取るようにしたものである。これにより、工具ホルダの管理を正確に且つ容易に行うことができる。 Such an IC tag receives radio waves from an external writer device, stores data related to the tool holder in the IC chip, and reads the stored data by bringing an external reader device close to the IC tag. Thereby, management of a tool holder can be performed accurately and easily.
　ＩＣタグは、工具ホルダの所要個所に埋設した状態で取り付けられる。特許文献１に記載の技術では、ＩＣタグ（ツールＩＤ）を取付具の凹部に保持し、工具ホルダに形成された孔部に取付具をねじ止めすることで工具ホルダにＩＣタグを取付けている。また、特許文献２に記載の技術では、ＩＣタグ（データ識別チップ）の外周面に段部を形成し、この段部と工具ホルダに形成された孔部との間に止め輪を配置することで、工具ホルダにＩＣタグを取付けている。その他、ＩＣタグは、工具ホルダに形成された孔部に対して接着剤を用いて取付けることが考えられる。 The IC tag is attached in a state where it is embedded in the required part of the tool holder. In the technique described in Patent Document 1, the IC tag (tool ID) is held in the recess of the fixture, and the IC tag is attached to the tool holder by screwing the fixture into a hole formed in the tool holder. . In the technique described in Patent Document 2, a step is formed on the outer peripheral surface of the IC tag (data identification chip), and a retaining ring is disposed between the step and a hole formed in the tool holder. The IC tag is attached to the tool holder. In addition, it is conceivable that the IC tag is attached to the hole formed in the tool holder using an adhesive.

　特許文献１に記載の技術では、ＩＣタグの厚さが薄い場合には、工具ホルダの外面にねじ孔を設けることができず、ＩＣタグを工具ホルダに取付けることができない。また、ＩＣタグの取付具は、ＩＣタグを保持する凹部とねじ止め用の取付け部とを並列に設けて構成されるため、工具ホルダにおいてＩＣタグの取付け領域が大きくなる。 In the technique described in Patent Document 1, when the IC tag is thin, a screw hole cannot be provided on the outer surface of the tool holder, and the IC tag cannot be attached to the tool holder. Further, since the IC tag mounting tool is configured by providing the recess for holding the IC tag and the mounting portion for screwing in parallel, the mounting area of the IC tag in the tool holder becomes large.
　特許文献２に記載の技術では、ＩＣタグの外部形状を加工する必要があるため、例えば一般的な形状である円板状のＩＣタグは工具ホルダに取付けることはできない。接着剤を用いて工具ホルダにＩＣタグを取付ける場合には、円板状のＩＣタグを用いることができる。しかし、接着剤を用いて一旦取付けられたＩＣタグは、工具ホルダから取り外して再使用することは困難である。また、接着剤を用いるＩＣタグの取付方法においては、工具ホルダの使用の際に遠心力を受けてＩＣタグが工具ホルダから脱落するおそれや、接着効果が十分に発揮されるまで時間がかかる等の問題がある。このように、ＩＣタグを工具ホルダに取付ける上で改善の余地があった。 In the technique described in Patent Document 2, since the external shape of the IC tag needs to be processed, for example, a disk-shaped IC tag having a general shape cannot be attached to the tool holder. When the IC tag is attached to the tool holder using an adhesive, a disk-shaped IC tag can be used. However, an IC tag once attached using an adhesive is difficult to remove from the tool holder and reuse. In addition, in the method of attaching an IC tag using an adhesive, there is a risk that the IC tag may drop from the tool holder due to centrifugal force when the tool holder is used, and it takes time until the adhesive effect is sufficiently exhibited. There is a problem. Thus, there is room for improvement in attaching the IC tag to the tool holder.
　そこで、工具ホルダに対しＩＣタグを簡易且つ安定的に取付けることができるＩＣタグの取付構造が望まれている。 Therefore, there is a demand for an IC tag mounting structure capable of easily and stably mounting an IC tag to a tool holder.
　本発明に係るＩＣタグの取付構造の特徴構成は、工具ホルダの外面に設けられた凹部と、円板状のＩＣタグと、環状に形成されたＩＣタグ保持部と、を備え、前記凹部に前記ＩＣタグが前記ＩＣタグ保持部に外嵌された状態で配置されるとともに、前記ＩＣタグ保持部が弾性変形することにより前記ＩＣタグが前記凹部に保持される点にある。 The characteristic configuration of the IC tag mounting structure according to the present invention includes a recess provided on the outer surface of the tool holder, a disc-shaped IC tag, and an IC tag holding portion formed in an annular shape. The IC tag is arranged in a state of being externally fitted to the IC tag holding portion, and the IC tag is held in the recess when the IC tag holding portion is elastically deformed.
　本構成によれば、円板状のＩＣタグがＩＣタグ保持部に外嵌された状態で工具ホルダの凹部に配置される。このため、ＩＣタグの形状に合うＩＣタグ保持部を構成することで、ＩＣタグを、その外形を加工することなく工具ホルダに取付けることができる。また、ＩＣタグ保持部が弾性変形することでＩＣタグが工具ホルダの凹部に保持されるため、工具ホルダにＩＣタグを安定的に保持することができる。 According to this configuration, the disc-shaped IC tag is disposed in the recess of the tool holder in a state of being fitted on the IC tag holding portion. For this reason, the IC tag can be attached to the tool holder without processing its outer shape by configuring the IC tag holding portion that matches the shape of the IC tag. In addition, since the IC tag is held in the recess of the tool holder by the elastic deformation of the IC tag holding portion, the IC tag can be stably held in the tool holder.
　前記ＩＣタグ保持部は、前記凹部の開口側の端部に前記ＩＣタグの端面の一部に当接する当接部を有するとともに、前記ＩＣタグを前記凹部に保持する弾性部材を含んでもよい。 The IC tag holding portion may include an abutting portion that abuts a part of the end face of the IC tag at an opening side end portion of the concave portion, and may include an elastic member that holds the IC tag in the concave portion.
　ＩＣタグ保持部に外嵌されたＩＣタグは、工具ホルダの外面から端面が露出した状態で取付けられて、工具ホルダが回転する際に遠心力を受ける。このため、ＩＣタグ保持部に対するＩＣタグの嵌合力が弱い場合には、ＩＣタグがＩＣタグ保持部から抜け出るおそれがある。そこで、本構成では、ＩＣタグ保持部が凹部の開口側の端部にＩＣタグの端面の一部に当接する当接部を有する。これにより、ＩＣタグ保持部に外嵌されたＩＣタグの移動が当接部によって規制される。その結果、ＩＣタグ保持部からのＩＣタグの抜け出しが確実に防止でき、ＩＣタグを工具ホルダに安定的に保持することができる。また、ＩＣタグがＩＣタグ保持部に含まれる弾性部材によって保持されるため、工具ホルダにＩＣタグを簡易に取付けることができる。 The IC tag externally fitted to the IC tag holder is attached with the end face exposed from the outer surface of the tool holder, and receives a centrifugal force when the tool holder rotates. For this reason, when the fitting force of the IC tag to the IC tag holding part is weak, the IC tag may come out of the IC tag holding part. Therefore, in this configuration, the IC tag holding part has an abutting part that abuts a part of the end face of the IC tag at the end part on the opening side of the recess. Thereby, the movement of the IC tag fitted on the IC tag holding portion is restricted by the contact portion. As a result, it is possible to reliably prevent the IC tag from slipping out of the IC tag holding portion, and it is possible to stably hold the IC tag in the tool holder. Further, since the IC tag is held by the elastic member included in the IC tag holding portion, the IC tag can be easily attached to the tool holder.
　前記ＩＣタグ保持部は、前記凹部の開口側の端部に前記ＩＣタグの端面の一部に当接する当接部を有するとともに、弾性変形可能に構成されて前記凹部に係合する係合部を有してもよい。 The IC tag holding part has an abutting part that abuts a part of the end surface of the IC tag at an end part on the opening side of the concave part, and is configured to be elastically deformable and engage with the concave part You may have.
　本構成では、ＩＣタグ保持部が凹部の開口側の端部にＩＣタグの端面の一部に当接する当接部を有する。これにより、ＩＣタグ保持部に外嵌されたＩＣタグの移動が当接部によって規制されるため、ＩＣタグを工具ホルダに安定的に保持することができる。また、ＩＣタグ保持部が弾性変形する係合部を有するので、ＩＣタグを工具ホルダに簡易に取付けることができ、ＩＣタグを工具ホルダに取付けるための部品点数を少なくすることもできる。 In this configuration, the IC tag holding part has an abutting part that abuts a part of the end face of the IC tag at the end of the recess on the opening side. Thereby, since the movement of the IC tag fitted on the IC tag holding part is regulated by the contact part, the IC tag can be stably held in the tool holder. Further, since the IC tag holding portion has an engaging portion that is elastically deformed, the IC tag can be easily attached to the tool holder, and the number of parts for attaching the IC tag to the tool holder can be reduced.

Thereby, a rectangular notch 27 is formed between the plurality of legs 26. The inner peripheral surface 21 a of the cylindrical portion 21 corresponds to the outer diameter of the IC tag 1, and the inner peripheral surface 26 a of the leg portion 26 has a diameter larger than the outer diameter of the IC tag 1. In the IC tag holding portion 2, the leg portion 26 is configured to be elastically deformable, and a claw portion 26b (an example of an engaging portion) is formed to protrude radially outward. The leg part 26 is elastically deformed, and the claw part 26 b is engaged with the groove part 17 of the recessed part 15, whereby the IC tag 1 and the IC tag holding part 2 are held in the recessed part 15.
　本実施形態において、凹部１５の内周面１６には、溝部１７に連通する複数の縦溝１８がＩＣタグ保持部２の脚部２６に対応する位置に分散して形成されている。こうした縦溝１８に対してピン杆等を有する治具を挿入し、当該治具によって脚部２６を径方向内方に押圧する。これにより、凹部１５からＩＣタグ１及びＩＣタグ保持部２を容易に取り外すことができる。 In the present embodiment, a plurality of vertical grooves 18 communicating with the groove portion 17 are formed on the inner peripheral surface 16 of the concave portion 15 at positions corresponding to the leg portions 26 of the IC tag holding portion 2. A jig having a pin rod or the like is inserted into the vertical groove 18 and the leg portion 26 is pressed radially inward by the jig. Thereby, the IC tag 1 and the IC tag holding part 2 can be easily removed from the recess 15.
〔第３実施形態の変形例〕
　第１実施形態に示される、凹部１５に縦溝１８を設ける形態に代えて、図９に示すように、ＩＣタグ保持部２において、外周面４のうち脚部２６の部位に縦溝２４を設けてもよい。この場合は、縦溝２４にピン杆等を有する治具を挿入し脚部２６を径方向内方に押圧することで、凹部１５からＩＣタグ１及びＩＣタグ保持部２を取り外すことができる。 [Modification of Third Embodiment]
As shown in FIG. 9, in the IC tag holding unit 2, the vertical groove 24 is formed at the site of the leg portion 26 in the outer peripheral surface 4, instead of the configuration in which the vertical groove 18 is provided in the recess 15 shown in the first embodiment. It may be provided. In this case, the IC tag 1 and the IC tag holding part 2 can be removed from the recess 15 by inserting a jig having a pin rod or the like into the vertical groove 24 and pressing the leg part 26 inward in the radial direction.
〔第４実施形態〕
　図１０及び図１１に示すように、本実施形態のＩＣタグ保持部２は、軸芯Ｘの方向において凹部１５の開口側の筒部２１と、筒部２１から凹部１５の開口とは反対の側（奥側）に向けて延設される２つの脚部２６と、２本の脚部２６から周方向に延設される円弧部２８（係合部の一例）とを有してもよい。２つの脚部２６は周方向において対向する位置に設けられ、筒部２１と円弧部２８との間にはスリット２９が形成されている。円弧部２８はＩＣタグ保持部２の外周面４よりも径方向外側に突出しており、径方向に弾性変形可能に構成されている。このため、円弧部２８が凹部１５の溝部１７に係合することで、凹部１５にＩＣタグ１及びＩＣタグ保持部２が保持される。 [Fourth Embodiment]
As shown in FIGS. 10 and 11, the IC tag holding unit 2 according to the present embodiment is opposite to the cylindrical portion 21 on the opening side of the concave portion 15 in the direction of the axis X and the opening from the cylindrical portion 21 to the concave portion 15. Two leg portions 26 extending toward the side (back side) and an arc portion 28 (an example of an engaging portion) extending in the circumferential direction from the two leg portions 26 may be included. . The two leg portions 26 are provided at positions facing each other in the circumferential direction, and a slit 29 is formed between the tube portion 21 and the arc portion 28. The arc portion 28 protrudes radially outward from the outer peripheral surface 4 of the IC tag holding portion 2 and is configured to be elastically deformable in the radial direction. For this reason, the IC tag 1 and the IC tag holding part 2 are held in the concave part 15 by the arc part 28 engaging with the groove part 17 of the concave part 15.
　図１１に示すように、凹部１５の内周面１６には溝部１７に連通する縦溝１８が複数形成されている。縦溝１８は円弧部２８に対応する位置に設けられている。こうすると、縦溝１８にピン杆等を有する治具を挿入し円弧部２８を内周側に押圧することで、凹部１５からＩＣタグ１及びＩＣタグ保持部２を取り外すことができる。 As shown in FIG. 11, a plurality of vertical grooves 18 communicating with the groove portion 17 are formed on the inner peripheral surface 16 of the recess 15. The vertical groove 18 is provided at a position corresponding to the arc portion 28. In this way, the IC tag 1 and the IC tag holding portion 2 can be removed from the recess 15 by inserting a jig having a pin rod or the like into the vertical groove 18 and pressing the arc portion 28 toward the inner peripheral side.
〔第５実施形態〕
　上記の各実施形態では、ＩＣタグ保持部２において凹部１５の開口側の端部にＩＣタグ１の端面の外周縁１ａに当接するよう全周に当接部２２を設ける例を示した。図１２及び図１３に示すように、当接部２２ａはＩＣタグ１の端面の外周縁１ａの一部に当接する形状でもよい。ＩＣタグ１が取付けられる工具ホルダ１０の外面１４ａは、周状の曲面であることが多い。ＩＣタグ１は、非接触型のリーダ・ライタ装置によって良好にデータを読み書きできるよう、工具ホルダ１０の外面１４ａに近接した位置に配置されることが好ましい。しかし、端部が平面のＩＣタグ１を工具ホルダ１０の曲面である外面に配置する場合には、ＩＣタグ１の端面に当接部２２が存在することで、ＩＣタグ１は全体が凹部１５の奥側に後退した位置になる。 [Fifth Embodiment]
In each of the above-described embodiments, an example in which the contact portion 22 is provided on the entire periphery of the IC tag holding portion 2 so as to be in contact with the outer peripheral edge 1a of the end face of the IC tag 1 at the end portion on the opening side of the concave portion 15 has been described. As shown in FIG. 12 and FIG. 13, the contact portion 22 a may have a shape that contacts a part of the outer peripheral edge 1 a of the end face of the IC tag 1. The outer surface 14a of the tool holder 10 to which the IC tag 1 is attached is often a circumferential curved surface. The IC tag 1 is preferably arranged at a position close to the outer surface 14a of the tool holder 10 so that data can be satisfactorily read and written by a non-contact type reader / writer device. However, when the IC tag 1 having a flat end is disposed on the outer surface which is the curved surface of the tool holder 10, the contact portion 22 exists on the end surface of the IC tag 1, so that the IC tag 1 is entirely recessed 15. It will be in a position retracted to the back side.
　ここで、ＩＣタグ１を工具ホルダ１０の外面１４ａに最も近づけて配置した場合、軸芯周りの方向ではＩＣタグ１の端部が外面１４ａに近接するが、軸芯Ｘの方向ではＩＣタグ１の端部は外面１４ａから奥側に後退した位置となる。そこで、本実施形態では、ＩＣタグ保持部２において、当接部２２ａを軸芯Ｘの方向の両端側のみに設けるよう構成した。これにより、ＩＣタグ保持部２に当接部２２ａを設けた場合であっても、ＩＣタグ１を工具ホルダ１０の外面１４ａに近接する位置に配置することができる。 Here, when the IC tag 1 is arranged closest to the outer surface 14a of the tool holder 10, the end of the IC tag 1 is close to the outer surface 14a in the direction around the axis, but the IC tag 1 is in the direction of the axis X. The end of this is a position retracted from the outer surface 14a to the back side. Therefore, in the present embodiment, the IC tag holding unit 2 is configured to be provided with the contact portions 22a only on both ends in the direction of the axis X. Thereby, even when the contact portion 22 a is provided in the IC tag holding portion 2, the IC tag 1 can be disposed at a position close to the outer surface 14 a of the tool holder 10.

(1) In the above embodiment, the vertical groove 18 is formed on the inner peripheral surface 16 facing the IC tag holding portion 2 in the recess 15 and the vertical groove 24 is formed on the outer peripheral surface 4 of the IC tag holding portion 2. Although an example is shown, the vertical grooves 18 and 24 may be omitted.
（２）図１４及び図１５に示すように、ＩＣタグ１として外周面に段部１ｃを有するものを用いる場合には、ＩＣタグ保持部２として折り返されて形成された板ばね２ａを用いることができる。板ばね２ａは、例えば凹部１５に対して周方向の４カ所に分散して溶接等により固定される。凹部１５に板ばね２ａを固定した後、ＩＣタグ１を凹部１５に挿入することで段部１ｃに板ばね２ａの端部が係合する。これにより、凹部１５に対するＩＣタグ１の取付けが完了する。 (2) As shown in FIGS. 14 and 15, when an IC tag 1 having a stepped portion 1 c on the outer peripheral surface is used, a leaf spring 2 a formed by folding back as the IC tag holding portion 2 is used. Can do. For example, the leaf spring 2a is dispersed at four locations in the circumferential direction with respect to the recess 15 and fixed by welding or the like. After fixing the leaf spring 2 a to the recess 15, the end of the leaf spring 2 a is engaged with the step portion 1 c by inserting the IC tag 1 into the recess 15. Thereby, the attachment of the IC tag 1 to the recess 15 is completed.
