Description

乗客コンベヤのステップの製造方法Passenger conveyor step manufacturing method
　この発明は、ステップチェーンが接続されているステップ軸にステップ本体を取り付ける乗客コンベヤのステップの製造方法に関するものである。 This invention relates to a passenger conveyor step manufacturing method in which a step body is attached to a step shaft to which a step chain is connected.
　従来、ステップ軸に周方向の段部を形成し、段部にスリーブを押し当てることによりステップ軸に対するスリーブの位置を決め、ステップ軸に対して位置決めされたスリーブにステップ本体を嵌めることによりステップの位置を決める乗客コンベヤが知られている（例えば特許文献１参照）。 Conventionally, a stepped portion in the circumferential direction is formed on the step shaft, the position of the sleeve with respect to the step shaft is determined by pressing the sleeve against the stepped portion, and the step body is fitted into the sleeve positioned with respect to the step shaft. A passenger conveyor for determining the position is known (see, for example, Patent Document 1).
　また、従来、ステップ軸に周方向の溝を形成するとともに、スリーブの内周面に突起を形成し、スリーブの突起をステップ軸の溝に嵌めることによりステップ軸に対するスリーブの位置を決め、ステップ軸に対して位置決めされたスリーブにステップ本体を嵌めることによりステップの位置を決める乗客コンベヤも知られている（例えば特許文献２参照）。 Conventionally, a circumferential groove is formed on the step shaft, a protrusion is formed on the inner peripheral surface of the sleeve, and the sleeve is positioned relative to the step shaft by fitting the protrusion of the sleeve into the groove of the step shaft. There is also known a passenger conveyor that determines the position of a step by fitting a step body to a sleeve positioned with respect to (see, for example, Patent Document 2).
　さらに、従来、ステップ軸にスリーブをスライド可能に取り付け、スリーブの軸線方向両側に配置されたクランプをステップ軸に取り付けることにより、ステップ軸に対するスリーブの位置を決める乗客コンベヤも知られている（例えば特許文献３参照）。 Further, conventionally, a passenger conveyor is known in which a sleeve is slidably attached to a step shaft, and clamps arranged on both sides in the axial direction of the sleeve are attached to the step shaft to determine the position of the sleeve with respect to the step shaft (for example, patents). Reference 3).

　しかし、特許文献１に示されている従来の乗客コンベヤでは、段部の加工精度が悪いと、ステップ軸に対するステップの位置の精度が悪くなってしまう。また、特許文献２に示されている従来の乗客コンベヤでも、ステップ軸の溝又はスリーブの突起の加工精度が悪いと、ステップ軸に対するステップの位置の精度が悪くなってしまう。さらに、特許文献１及び２に示されている従来の乗客コンベヤでは、ステップ軸に段部又は溝の加工が必要になるので、ステップ軸の加工に手間がかかってしまう。 However, in the conventional passenger conveyor disclosed in Patent Document 1, if the processing accuracy of the stepped portion is poor, the accuracy of the step position with respect to the step axis is deteriorated. Further, even in the conventional passenger conveyor shown in Patent Document 2, if the processing accuracy of the groove of the step shaft or the projection of the sleeve is poor, the accuracy of the step position with respect to the step shaft is deteriorated. Furthermore, in the conventional passenger conveyors disclosed in Patent Documents 1 and 2, it is necessary to process a stepped portion or a groove on the step shaft, so that it takes time to process the step shaft.
　また、特許文献１～３に示されている従来の乗客コンベヤでは、ステップ本体の個々の寸法のばらつきによって、複数のステップを無端状に連結するステップチェーンからステップ本体の側面までの位置関係がステップ本体ごとに変わってしまう。これにより、ステップチェーンと、ステップチェーンが巻き掛けられているスプロケットとの噛み合い状態が悪化したり、互いに隣接する２つのステップの一方のライザの溝と他方のクリートとの位置関係が悪化したりしてしまう。 Further, in the conventional passenger conveyors disclosed in Patent Documents 1 to 3, the positional relationship from the step chain that connects a plurality of steps in an endless manner to the side surface of the step body is determined by the variation in individual dimensions of the step body. It will change from one body to another. As a result, the meshing state of the step chain and the sprocket around which the step chain is wound may deteriorate, or the positional relationship between the groove of one riser of two adjacent steps and the other cleat may deteriorate. End up.
　この発明は、上記のような課題を解決するためになされたものであり、ステップ軸に対するステップ本体の位置決めを容易に行うことができ、ステップ軸に対するステップ本体の位置決め精度を向上させることができる乗客コンベヤのステップの製造方法を得ることを目的とする。 The present invention has been made to solve the above-described problems, and can easily position the step body with respect to the step shaft, and can improve the positioning accuracy of the step body with respect to the step shaft. It aims at obtaining the manufacturing method of the step of a conveyor.
　この発明に係る乗客コンベヤのステップの製造方法は、ステップ軸の端部に接続されているステップチェーンのリンクプレートと、ステップ軸に設けられているステップ本体との間に位置決め具を配置し、位置決め具本体をリンクプレートに接触させる位置決め具配置工程、及びステップ本体を位置決め具に接触させるステップ本***置決め工程を備えている。 According to the passenger conveyor step manufacturing method according to the present invention, a positioning tool is disposed between a link plate of a step chain connected to an end of the step shaft and a step body provided on the step shaft, and positioning is performed. A positioning tool placement step for bringing the tool body into contact with the link plate; and a step body positioning step for bringing the step body into contact with the positioning tool.
　この発明に係る乗客コンベヤのステップの製造方法によれば、ステップ本体の位置決めのための加工をステップ軸に対して行う必要がなくなるとともに、ステップ本体及びステップ軸の加工精度を高める必要もなくなり、ステップ軸に対するステップ本体の位置決めを容易に行うことができる。また、リンクプレートからステップ本体までの距離を、位置決め具本体の寸法に応じた一定の距離にすることができるので、リンクプレートからステップ本体までの距離がステップごとにばらついてしまうことを防止することができ、ステップ軸に対するステップ本体の位置決め精度を向上させることができる。 According to the passenger conveyor step manufacturing method according to the present invention, it is not necessary to perform processing for positioning the step body on the step axis, and it is not necessary to increase the processing accuracy of the step body and the step axis. The step body can be easily positioned with respect to the shaft. In addition, since the distance from the link plate to the step body can be a constant distance according to the dimensions of the positioning tool body, it is possible to prevent the distance from the link plate to the step body from varying from step to step. Thus, the positioning accuracy of the step body with respect to the step axis can be improved.

　図２は、図１のステップ２のステップ本体の位置決めを行っているときの状態を示す模式的な一部断面図である。また、図３は、図２のＩＩＩ－ＩＩＩ線に沿った断面図である。ステップ２は、トラス１の幅方向に沿って配置されているステップ軸８と、ステップ軸８に設けられているスリーブ９と、スリーブ９をステップ軸８に固定するクランプ１０と、スリーブ９を介してステップ軸８に設けられているステップ本体１１とを有している。 FIG. 2 is a schematic partial cross-sectional view showing a state when the step main body is positioned in step 2 of FIG. FIG. 3 is a sectional view taken along line III-III in FIG. Step 2 includes a step shaft 8 disposed along the width direction of the truss 1, a sleeve 9 provided on the step shaft 8, a clamp 10 that fixes the sleeve 9 to the step shaft 8, and the sleeve 9. And a step body 11 provided on the step shaft 8.
　スリーブ９は、ステップ軸８に対してステップ軸８の軸線方向へスライド可能になっている。また、スリーブ９は、円筒状のスリーブ本体９１と、スリーブ本体９１の端部の外周面から径方向外側へ突出しているフランジ部９２とを有している。スリーブ９は、スリーブ本体９１にステップ軸８を通した状態でステップ軸８に設けられている。この例では、スリーブ９が樹脂で構成されている。 The sleeve 9 is slidable in the axial direction of the step shaft 8 with respect to the step shaft 8. The sleeve 9 includes a cylindrical sleeve main body 91 and a flange portion 92 that protrudes radially outward from the outer peripheral surface of the end portion of the sleeve main body 91. The sleeve 9 is provided on the step shaft 8 with the step shaft 8 passed through the sleeve body 91. In this example, the sleeve 9 is made of resin.
　クランプ１０は、ステップ軸８を囲むＣ字状のクランプ本体１０１と、クランプ本体１０１のＣ字状の両端部を連結するクランプ締結具であるクランプねじ１０２とを有している。クランプ１０は、クランプ本体１０１がクランプねじ１０２で締め付けられることによりステップ軸８に固定される。クランプねじ１０２の操作によってクランプ１０のステップ軸８に対する締め付けが緩むと、クランプ１０はステップ軸８に対してステップ軸８の軸線方向へスライド可能になる。 The clamp 10 has a C-shaped clamp body 101 surrounding the step shaft 8 and a clamp screw 102 which is a clamp fastener for connecting both C-shaped ends of the clamp body 101. The clamp 10 is fixed to the step shaft 8 by clamping the clamp body 101 with a clamp screw 102. When the clamp 10 is loosened by the operation of the clamp screw 102 with respect to the step shaft 8, the clamp 10 can slide in the axial direction of the step shaft 8 with respect to the step shaft 8.
　ステップ本体１１は、踏板１１１と、踏板１１１に固定され、踏板１１１を支持する支持体１１２とを有している。支持体１１２は、ステップ本体１１の幅方向について互いに離して配置された一対の取付部１１３を有している。スリーブ９には、取付部１１３が取り付けられている。 The step body 11 has a tread 111 and a support 112 fixed to the tread 111 and supporting the tread 111. The support body 112 has a pair of attachment portions 113 that are arranged apart from each other in the width direction of the step body 11. An attachment portion 113 is attached to the sleeve 9.
　各取付部１１３には、凹部１１４がそれぞれ形成されている。凹部１１４の内面には、スリーブ本体９１の外周面が嵌っている。取付部１１３は、凹部１１４の内面がスリーブ本体９１の外周面に嵌った状態でスリーブ９に取り付けられている。 A recess 114 is formed in each mounting portion 113. The outer peripheral surface of the sleeve body 91 is fitted to the inner surface of the recess 114. The attachment portion 113 is attached to the sleeve 9 with the inner surface of the recess 114 fitted to the outer peripheral surface of the sleeve body 91.
　凹部１１４の開放部は、スリーブ本体９１の外径よりも狭くなっている。これにより、取付部１１３は、凹部１１４の開放部を通してスリーブ９から外れないようになっている。また、凹部１１４の開放部は、ステップ軸８の外径よりも広くなっている。 The open part of the recess 114 is narrower than the outer diameter of the sleeve body 91. Thus, the attachment portion 113 is prevented from being detached from the sleeve 9 through the opening portion of the recess 114. Further, the open portion of the recess 114 is wider than the outer diameter of the step shaft 8.
　凹部１１４の内径は、フランジ部９２の外径よりも小さくなっている。フランジ部９２は、取付部１１３の側面に接触している。クランプ１０は、スリーブ９のフランジ部９２側の端面に接触した状態でステップ軸８に固定されている。これにより、スリーブ９及びステップ本体１１のそれぞれの位置がステップ軸８の軸線方向について固定されている。 The inner diameter of the recess 114 is smaller than the outer diameter of the flange portion 92. The flange portion 92 is in contact with the side surface of the attachment portion 113. The clamp 10 is fixed to the step shaft 8 in contact with the end surface of the sleeve 9 on the flange portion 92 side. Thereby, the respective positions of the sleeve 9 and the step body 11 are fixed in the axial direction of the step shaft 8.
　一対のステップチェーン３は、ステップ軸８の両端部にそれぞれ接続されている。また、ステップチェーン３は、ステップチェーン３の長さ方向へ並ぶ複数のリンクプレート３１と、ステップチェーン３の長さ方向で互いに隣り合うリンクプレート３１を回転自在に連結する複数のチェーンシャフト３２と、各チェーンシャフト３２に回転自在に設けられている複数のローラ３３とを有している。即ち、この例では、ステップチェーン３がローラチェーンになっている。 The pair of step chains 3 are connected to both ends of the step shaft 8 respectively. The step chain 3 includes a plurality of link plates 31 arranged in the length direction of the step chain 3, a plurality of chain shafts 32 that rotatably connect the link plates 31 adjacent to each other in the length direction of the step chain 3, Each chain shaft 32 has a plurality of rollers 33 rotatably provided. That is, in this example, the step chain 3 is a roller chain.
　チェーンシャフト３２は、図３に示すように、ステップ軸８の端面から突出している。また、チェーンシャフト３２は、ステップ軸８と同軸に配置されている。さらに、チェーンシャフト３２の外径は、ステップ軸８の外径よりも小さくなっている。これにより、ステップ軸８の端面とチェーンシャフト３２との境界には、ステップ軸８の周方向に沿った段差部がステップ軸８の全周に形成されている。また、リンクプレート３１とステップ軸８の端面との間には、隙間１２が存在している。 The chain shaft 32 protrudes from the end surface of the step shaft 8 as shown in FIG. The chain shaft 32 is arranged coaxially with the step shaft 8. Further, the outer diameter of the chain shaft 32 is smaller than the outer diameter of the step shaft 8. Thereby, a step portion along the circumferential direction of the step shaft 8 is formed on the entire circumference of the step shaft 8 at the boundary between the end surface of the step shaft 8 and the chain shaft 32. In addition, a gap 12 exists between the link plate 31 and the end surface of the step shaft 8.
　各ローラ３３は、トラス１に取り付けられている案内レール上を転動する。各ローラ３３が案内レール上を転動することにより、ステップ２が案内レールに案内される。 Each roller 33 rolls on a guide rail attached to the truss 1. As each roller 33 rolls on the guide rail, step 2 is guided to the guide rail.
　次に、ステップ２を組み立てるときの手順について説明する。ステップ２を組み立てるときには、一対のスリーブ９及び一対のクランプ１０をステップ軸８に予め取り付けておく。このとき、各スリーブ９及び各クランプ１０は、ステップ軸８に対してスライド可能にしておく。また、このとき、ステップ軸８に嵌めた各スリーブ９及び各クランプ１０は、ステップ軸８の軸線方向内側へスライドさせておく。 Next, the procedure for assembling Step 2 will be described. When the step 2 is assembled, the pair of sleeves 9 and the pair of clamps 10 are attached to the step shaft 8 in advance. At this time, each sleeve 9 and each clamp 10 are slidable with respect to the step shaft 8. At this time, the sleeves 9 and the clamps 10 fitted to the step shaft 8 are slid inward in the axial direction of the step shaft 8.
　この後、ステップ本体１１を持ちながら、スリーブ９の位置とは異なる位置で凹部１１４の開放部から凹部１１４内にステップ軸８を挿入し、凹部１１４内にステップ軸８を挿入した状態でスリーブ９をステップ軸８の軸線方向外側へスライドさせて、スリーブ本体９１を凹部１１４の内面に嵌める。これにより、ステップ本体１１がスリーブ９を介してステップ軸８に連結される。 Thereafter, while holding the step main body 11, the step shaft 8 is inserted into the recess 114 from the opening of the recess 114 at a position different from the position of the sleeve 9, and the sleeve 9 is inserted with the step shaft 8 inserted into the recess 114. Is slid outward in the axial direction of the step shaft 8 to fit the sleeve body 91 into the inner surface of the recess 114. As a result, the step body 11 is connected to the step shaft 8 via the sleeve 9.
　この後、位置決め具２１を用いて、ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行う。 Thereafter, using the positioning tool 21, the step body 11 is positioned with respect to the step shaft 8 in the axial direction of the step shaft 8.
　図４は、図１の位置決め具２１を示す斜視図である。位置決め具２１は、板状の位置決め具本体２２と、位置決め具本体２２に設けられている保持用ねじ２３とを有している。 FIG. 4 is a perspective view showing the positioning tool 21 of FIG. The positioning tool 21 includes a plate-shaped positioning tool body 22 and a holding screw 23 provided on the positioning tool body 22.
　位置決め具本体２２は、ベース部２２１と、ベース部２２１から突出して互いに対向する第１の対向部２２２及び第２の対向部２２３とを有している。ベース部２２１、第１の対向部２２２及び第２の対向部２２３のそれぞれの幅方向は、位置決め具本体２２の幅方向と一致している。 The positioning tool main body 22 includes a base portion 221, a first facing portion 222 and a second facing portion 223 that protrude from the base portion 221 and face each other. The width direction of each of the base portion 221, the first facing portion 222, and the second facing portion 223 coincides with the width direction of the positioning tool main body 22.
　位置決め具本体２２には、位置決め具本体２２の幅方向について対向する第１の基準面２２４及び第２の基準面２２５が形成されている。第１の基準面２２４及び第２の基準面２２５は、互いに平行になっている。また、第１の基準面２２４及び第２の基準面２２５は、ベース部２２１、第１の対向部２２２及び第２の対向部２２３のそれぞれに形成されている。 The positioning tool main body 22 is formed with a first reference surface 224 and a second reference surface 225 that face each other in the width direction of the positioning tool main body 22. The first reference surface 224 and the second reference surface 225 are parallel to each other. The first reference surface 224 and the second reference surface 225 are formed on the base portion 221, the first facing portion 222, and the second facing portion 223, respectively.
　第２の対向部２２３には、第１の基準面２２４に対して傾斜する傾斜面２２６が形成されている。傾斜面２２６は、ベース部２２１から第２の対向部２２３が突出する方向に沿った面である。これにより、第２の対向部２２３は、第１の対向部２２２と第２の対向部２２３との間の空間に向かって幅が連続的に狭くなるテーパ部になっている。 An inclined surface 226 that is inclined with respect to the first reference surface 224 is formed in the second facing portion 223. The inclined surface 226 is a surface along the direction in which the second facing portion 223 protrudes from the base portion 221. Accordingly, the second facing portion 223 is a tapered portion whose width is continuously narrowed toward the space between the first facing portion 222 and the second facing portion 223.
　第１の対向部２２２の幅は、第１の対向部２２２のどの位置でも一定になっている。また、第１の対向部２２２には、第１の対向部２２２を貫通するねじ穴が設けられている。保持用ねじ２３は、第１の対向部２２２のねじ穴に嵌った状態で第１の対向部２２２に設けられている。また、保持用ねじ２３は、第１の対向部２２２と第２の対向部２２３との間の空間に突出している。第１の対向部２２２からの保持用ねじ２３の突出量は、保持用ねじ２３を回す操作により調整可能になっている。保持用ねじ２３の先端部と第２の対向部２２３との間の距離は、保持用ねじ２３の突出量の変化に応じて変化する。 The width of the first facing portion 222 is constant at any position of the first facing portion 222. Further, the first facing portion 222 is provided with a screw hole penetrating the first facing portion 222. The holding screw 23 is provided in the first facing portion 222 in a state of being fitted in the screw hole of the first facing portion 222. The holding screw 23 protrudes into a space between the first facing portion 222 and the second facing portion 223. The amount of protrusion of the holding screw 23 from the first facing portion 222 can be adjusted by turning the holding screw 23. The distance between the front end portion of the holding screw 23 and the second facing portion 223 changes according to the change in the protruding amount of the holding screw 23.
　ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行うときには、まず、図２に示すように、リンクプレート３１とステップ本体１１との間に位置決め具本体２２を配置し、位置決め具本体２２をリンクプレート３１に接触させる（位置決め具配置工程）。 When positioning the step body 11 with respect to the step shaft 8 in the axial direction of the step shaft 8, first, as shown in FIG. 2, the positioning tool body 22 is arranged between the link plate 31 and the step body 11, and the positioning tool The main body 22 is brought into contact with the link plate 31 (positioning tool arranging step).
　このときの位置決め具配置工程では、図３に示すように、第１の基準面２２４をリンクプレート３１に向け、第２の基準面２２５をステップ本体１１に向けた状態で位置決め具本体２２を配置する。また、位置決め具配置工程では、第１の対向部２２２と第２の対向部２２３との間にステップ軸８を配置し、ステップ軸８の端面とリンクプレート３１との間の隙間１２にテーパ部である第２の対向部２２３を差し込む。これにより、第１の基準面２２４がリンクプレート３１に接触するとともに、傾斜面２２６がステップ軸８の端面の外周部に接触する。さらに、位置決め具配置工程では、保持用ねじ２３の先端部をステップ軸８の外周面に押し付けながら保持用ねじ２３を締め込む。これにより、第１の基準面２２４がリンクプレート３１に押し付けられる方向へ位置決め具本体２２が傾斜面２２６に案内され、位置決め具２１がステップ軸８とリンクプレート３１との間に保持される。 In the positioning tool arranging step at this time, as shown in FIG. 3, the positioning tool body 22 is placed with the first reference surface 224 facing the link plate 31 and the second reference surface 225 facing the step body 11. To do. In the positioning tool arranging step, the step shaft 8 is arranged between the first facing portion 222 and the second facing portion 223, and the tapered portion is formed in the gap 12 between the end surface of the step shaft 8 and the link plate 31. The 2nd opposing part 223 which is is inserted. As a result, the first reference surface 224 contacts the link plate 31 and the inclined surface 226 contacts the outer peripheral portion of the end surface of the step shaft 8. Further, in the positioning tool arranging step, the holding screw 23 is tightened while pressing the tip of the holding screw 23 against the outer peripheral surface of the step shaft 8. Thereby, the positioning tool main body 22 is guided to the inclined surface 226 in the direction in which the first reference surface 224 is pressed against the link plate 31, and the positioning tool 21 is held between the step shaft 8 and the link plate 31.
　位置決め具配置工程の後、スリーブ本体９１の外周面に取付部１１３を嵌めたまま、ステップ本体１１をステップ軸８の軸線方向へスライドさせ、ステップ軸８の軸線方向についてステップ本体１１の側面を位置決め具本体２２の第２の基準面２２５に接触させる。これにより、ステップ軸８に対するステップ本体１１の位置決めがステップ軸８の軸線方向について行われる（ステップ本***置決め工程）。 After the positioning tool arranging step, the step body 11 is slid in the axial direction of the step shaft 8 with the mounting portion 113 fitted on the outer peripheral surface of the sleeve body 91, and the side surface of the step body 11 is positioned in the axial direction of the step shaft 8. The tool main body 22 is brought into contact with the second reference surface 225. Thereby, the positioning of the step body 11 with respect to the step shaft 8 is performed in the axial direction of the step shaft 8 (step body positioning step).
　ステップ本***置決め工程の後、ステップ軸８に対してスリーブ９をスライドさせて、ステップ軸８の軸線方向についてスリーブ９のフランジ部９２を取付部１１３の側面に接触させる。これにより、ステップ軸８に対するスリーブ９の位置決めがステップ軸８の軸線方向について行われる（スリーブ位置決め工程）。 After the step body positioning step, the sleeve 9 is slid with respect to the step shaft 8, and the flange portion 92 of the sleeve 9 is brought into contact with the side surface of the mounting portion 113 in the axial direction of the step shaft 8. Thereby, the positioning of the sleeve 9 with respect to the step shaft 8 is performed in the axial direction of the step shaft 8 (sleeve positioning step).
　スリーブ位置決め工程の後、ステップ軸８に対してクランプ１０を移動させることによりスリーブ９のフランジ部９２側の端面にクランプ本体１０１を接触させ、クランプねじ１０２を締め込むことによりクランプ本体１０１をステップ軸８に固定する。これにより、ステップ軸８に対するスリーブ９の位置がステップ軸８の軸線方向について固定され、ステップ軸８に対するステップ本体１１の位置もステップ軸８の軸線方向について固定される（スリーブ固定工程）。 After the sleeve positioning step, the clamp 10 is moved with respect to the step shaft 8 to bring the clamp body 101 into contact with the end surface of the sleeve 9 on the flange portion 92 side, and the clamp screw 102 is tightened to move the clamp body 101 to the step shaft. Fix to 8. Thereby, the position of the sleeve 9 with respect to the step shaft 8 is fixed in the axial direction of the step shaft 8, and the position of the step body 11 with respect to the step shaft 8 is also fixed in the axial direction of the step shaft 8 (sleeve fixing step).
　スリーブ固定工程の後、位置決め具２１の保持用ねじ２３を緩めて、リンクプレート３１とステップ本体１１との間から位置決め具２１を外す（位置決め具取り外し工程）。このようにして、ステップ２が組み立てられる。 After the sleeve fixing step, the holding screw 23 of the positioning tool 21 is loosened, and the positioning tool 21 is removed from between the link plate 31 and the step body 11 (positioning tool removing process). In this way, step 2 is assembled.
　このようなステップ２の製造方法では、リンクプレート３１とステップ本体１１との間に位置決め具本体２２を配置して位置決め具本体２２をリンクプレート３１に接触させた後、ステップ本体１１を位置決め具本体２２に接触させるので、ステップ本体１１の位置決めのための加工をステップ軸８に対して行う必要がなくなるとともに、ステップ本体１１及びステップ軸８の加工精度を高める必要もなくなり、ステップ軸８に対するステップ本体１１の位置決めを容易に行うことができ、部品コストの削減も図ることができる。さらに、リンクプレート３１からステップ本体１１の側面までの距離を、位置決め具本体２２の寸法に応じた一定の距離にすることができるので、リンクプレート３１からステップ本体１１の側面までの距離がステップ２ごとにばらついてしまうことを防止することができ、ステップ軸８に対するステップ本体１１の位置決め精度を向上させることができる。 In such a manufacturing method of Step 2, the positioning tool main body 22 is arranged between the link plate 31 and the step main body 11, the positioning tool main body 22 is brought into contact with the link plate 31, and then the step main body 11 is moved to the positioning tool main body. 22, it is not necessary to perform processing for positioning the step body 11 on the step shaft 8, and it is not necessary to increase the processing accuracy of the step body 11 and the step shaft 8. 11 can be easily positioned, and the part cost can be reduced. Further, since the distance from the link plate 31 to the side surface of the step body 11 can be a constant distance according to the dimension of the positioning tool body 22, the distance from the link plate 31 to the side surface of the step body 11 is step 2. Therefore, it is possible to prevent the step body 11 from being varied, and the positioning accuracy of the step body 11 with respect to the step shaft 8 can be improved.
　ここで、図５は、図１の上部スプロケット４の周方向に沿って見たときの上部スプロケット４とステップチェーン３との噛み合い状態を示す要部構成図である。リンクプレート３１からステップ本体１１の側面までの距離のばらつきが各ステップ２間でなくなると、図５に示すように、各ステップ２のそれぞれにおけるステップチェーン３の位置をトラス１の幅方向について上部スプロケット４の位置に合わせることができ、ステップチェーン３と上部スプロケット４との噛み合い状態の悪化を防止することができる。また、同様に、ステップチェーン３と下部スプロケット５との噛み合い状態の悪化も防止することができる。 Here, FIG. 5 is a main part configuration diagram showing the meshing state of the upper sprocket 4 and the step chain 3 when viewed along the circumferential direction of the upper sprocket 4 of FIG. When the variation in the distance from the link plate 31 to the side surface of the step body 11 disappears between each step 2, as shown in FIG. 5, the position of the step chain 3 in each step 2 is changed to the upper sprocket in the width direction of the truss 1. 4, and the deterioration of the meshing state between the step chain 3 and the upper sprocket 4 can be prevented. Similarly, it is possible to prevent the meshing state between the step chain 3 and the lower sprocket 5 from being deteriorated.
　また、図６は、図１の互いに隣り合う２つのステップ２の一方のライザと他方の踏板との位置関係を示す要部構成図である。互いに隣り合う２つのステップ２のうち、一方のステップ本体１１の踏板１１１には複数の溝である踏板クリート１１ａが設けられ、他方のステップ本体１１のライザには複数の溝であるライザクリート１１ｂが設けられている。また、互いに隣り合う２つのステップ２は、一方のステップ本体１１の踏板クリート１１ａ間の複数の突起を他方のステップ本体１１の各ライザクリート１１ｂに挿入した状態で、配置されている。 FIG. 6 is a main part configuration diagram showing the positional relationship between one riser and the other tread of two adjacent steps 2 in FIG. Of the two steps 2 adjacent to each other, the tread 111 of one step body 11 is provided with a tread cleat 11a that is a plurality of grooves, and the riser cleat 11b that is a plurality of grooves is provided on the riser of the other step body 11. Is provided. Further, two adjacent steps 2 are arranged in a state where a plurality of protrusions between the tread plate cleats 11 a of one step body 11 are inserted into the riser cleats 11 b of the other step body 11.
　リンクプレート３１からステップ本体１１の側面までの距離のばらつきが各ステップ２間でなくなると、図６に示すように、互いに隣り合う２つのステップ本体１１の一方に対する他方の位置をトラス１の幅方向について合わせることができる。これにより、互いに隣り合う２つのステップ本体１１の位置関係の悪化を防止することができ、一方のステップ本体１１の踏板クリート１１ａ間の突起が他方のステップ本体１１のライザクリート１１ｂの内面に干渉することを防止することができる。 When the variation in the distance from the link plate 31 to the side surface of the step body 11 disappears between each step 2, the other position with respect to one of the two adjacent step bodies 11 as shown in FIG. Can be adapted. Thereby, it is possible to prevent the positional relationship between the two step bodies 11 adjacent to each other from deteriorating, and the projection between the tread cleats 11a of one step body 11 interferes with the inner surface of the riser cleat 11b of the other step body 11. This can be prevented.
　また、ステップ本体１１を位置決め具本体２２に接触させた後、ステップ本体１１の取付部１１３にスリーブ９を接触させ、スリーブ９を取付部１１３に接触させた状態で、クランプ１０によってステップ軸８に対するスリーブ９の位置をステップ軸８の軸線方向について固定するので、ステップ軸８に対するステップ本体１１の位置をずらすことなく、ステップ軸８に対するステップ本体１１の位置をステップ軸８の軸線方向について容易に固定することができる。 In addition, after the step body 11 is brought into contact with the positioning tool body 22, the sleeve 9 is brought into contact with the attachment portion 113 of the step body 11, and the sleeve 9 is brought into contact with the attachment portion 113. Since the position of the sleeve 9 is fixed in the axial direction of the step shaft 8, the position of the step main body 11 with respect to the step shaft 8 is easily fixed in the axial direction of the step shaft 8 without shifting the position of the step main body 11 with respect to the step shaft 8. can do.
　また、位置決め具配置工程では、ステップ軸８とリンクプレート３１との間の隙間１２にテーパ部である第２の対向部２２３を差し込んだ状態で保持用ねじ２３を締め付けることにより、位置決め具本体２２をリンクプレート３１に押し付けるので、リンクプレート３１に位置決め具本体２２をより確実に接触させることができ、ステップ軸８に対するステップ本体１１の位置決めをより正確に行うことができる。 In the positioning tool arranging step, the positioning tool body 22 is tightened by tightening the holding screw 23 in a state where the second facing portion 223 that is a tapered portion is inserted into the gap 12 between the step shaft 8 and the link plate 31. Is pressed against the link plate 31, the positioning tool main body 22 can be brought into contact with the link plate 31 more reliably, and the step main body 11 can be more accurately positioned with respect to the step shaft 8.
　なお、上記の例では、第２の対向部２２３がテーパ部になっているが、第１の基準面２２４がリンクプレート３１に接触した状態で位置決め具本体２２を保持することができるのであれば、第２の対向部２２３はテーパ部でなくてもよい。 In the above example, the second facing portion 223 is a tapered portion. However, as long as the positioning tool main body 22 can be held in a state where the first reference surface 224 is in contact with the link plate 31. The second facing portion 223 may not be a tapered portion.

The first reference surface 426 and the second reference surface 427 are parallel to each other. Further, the first reference surface 426 and the second reference surface 427 are formed on the first main body member 421 and the second main body member 422, respectively.
　第１の対向部４２３及び第２の対向部４２４のそれぞれには、第１の基準面４２６に対して傾斜する傾斜面４２８が形成されている。これにより、第１の対向部４２３及び第２の対向部４２４のそれぞれは、第１の対向部４２３と第２の対向部４２４との間の空間に向かって幅が連続的に狭くなるテーパ部になっている。 An inclined surface 428 that is inclined with respect to the first reference surface 426 is formed in each of the first facing portion 423 and the second facing portion 424. Accordingly, each of the first facing portion 423 and the second facing portion 424 has a tapered portion whose width continuously narrows toward the space between the first facing portion 423 and the second facing portion 424. It has become.
　ばね４３は、第１の本体部材４２１と第２の本体部材４２２との間に配置されている。また、ばね４３は、第１の対向部４２３と第２の対向部４２４とが互いに近づく方向へ第１の本体部材４２１及び第２の本体部材４２２を付勢する弾性復元力を発生している。他の構成は実施の形態１と同様である。 The spring 43 is disposed between the first main body member 421 and the second main body member 422. The spring 43 generates an elastic restoring force that urges the first main body member 421 and the second main body member 422 in a direction in which the first facing portion 423 and the second facing portion 424 approach each other. . Other configurations are the same as those in the first embodiment.
　次に、ステップ２を組み立てるときの手順について説明する。スリーブ９を介してステップ本体１１をステップ軸８に連結するまでの手順は、実施の形態１と同様である。スリーブ９を介してステップ本体１１をステップ軸８に連結した後、位置決め具４１を用いて、ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行う。 Next, the procedure for assembling Step 2 will be described. The procedure until the step body 11 is connected to the step shaft 8 via the sleeve 9 is the same as that of the first embodiment. After the step body 11 is connected to the step shaft 8 via the sleeve 9, the step body 11 is positioned with respect to the step shaft 8 in the axial direction of the step shaft 8 using the positioning tool 41.
　ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行うときには、まず、図７に示すように、リンクプレート３１とステップ本体１１との間に位置決め具本体４２を配置し、位置決め具本体４２をリンクプレート３１に接触させる（位置決め具配置工程）。 When positioning the step body 11 with respect to the step shaft 8 in the axial direction of the step shaft 8, first, as shown in FIG. 7, a positioning tool body 42 is disposed between the link plate 31 and the step body 11, and the positioning tool The main body 42 is brought into contact with the link plate 31 (positioning tool arranging step).
　位置決め具配置工程では、図８に示すように、第１の基準面４２６をリンクプレート３１に向け、第２の基準面４２７をステップ本体１１に向けた状態で位置決め具本体４２を配置する。また、位置決め具配置工程では、ばね４３の弾性復元力に逆らって位置決め具本体４２に力を加えることにより第１の本体部材４２１及び第２の本体部材４２２を互いに回動させて第１の対向部４２３と第２の対向部４２４との間の空間を広げた後、第１の対向部４２３と第２の対向部４２４との間にステップ軸８を配置し、位置決め具本体４２に加えている力を弱める。これにより、ばね４３の弾性復元力によって第１の対向部４２３及び第２の対向部４２４が互いに近づく方向へ第１の本体部材４２１及び第２の本体部材４２２が互いに回動し、ステップ軸８の端面とリンクプレート３１との間の隙間１２に第１の対向部４２３及び第２の対向部４２４が差し込まれる。このとき、第１の基準面４２６がリンクプレート３１に接触し、各傾斜面４２８がステップ軸８の端面の外周部に接触するとともに、ばね４３の弾性復元力によって第１の基準面４２６がリンクプレート３１に各傾斜面４２８に沿った方向へ押し付けられる。これにより、位置決め具４１がステップ軸８とリンクプレート３１との間に保持される。 In the positioning tool arranging step, as shown in FIG. 8, the positioning tool body 42 is placed with the first reference surface 426 facing the link plate 31 and the second reference surface 427 facing the step body 11. Further, in the positioning tool arranging step, the first body member 421 and the second body member 422 are rotated with respect to each other by applying a force to the positioning tool body 42 against the elastic restoring force of the spring 43, so that the first opposing members are opposed to each other. After expanding the space between the portion 423 and the second facing portion 424, the step shaft 8 is disposed between the first facing portion 423 and the second facing portion 424, and in addition to the positioning tool main body 42 We weaken power to be. Accordingly, the first main body member 421 and the second main body member 422 are rotated in the direction in which the first facing portion 423 and the second facing portion 424 approach each other by the elastic restoring force of the spring 43, and the step shaft 8 The first facing portion 423 and the second facing portion 424 are inserted into the gap 12 between the end surface of the first and the link plate 31. At this time, the first reference surface 426 contacts the link plate 31, each inclined surface 428 contacts the outer peripheral portion of the end surface of the step shaft 8, and the first reference surface 426 is linked by the elastic restoring force of the spring 43. The plate 31 is pressed in a direction along each inclined surface 428. Thereby, the positioning tool 41 is held between the step shaft 8 and the link plate 31.
　位置決め具配置工程の後のステップ本***置決め工程、スリーブ位置決め工程、スリーブ固定工程は、実施の形態１と同様である。 The step body positioning process, sleeve positioning process, and sleeve fixing process after the positioning tool arranging process are the same as those in the first embodiment.
　スリーブ固定工程の後、ばね４３の弾性復元力に逆らって位置決め具本体４２に力を加えることにより第１の対向部４２３と第２の対向部４２４との間の空間を広げて、ステップ軸８とリンクプレート３１との間から位置決め具４１を外す（位置決め具取り外し工程）。このようにして、ステップ２が組み立てられる。 After the sleeve fixing step, a force is applied to the positioning tool main body 42 against the elastic restoring force of the spring 43 to widen the space between the first facing portion 423 and the second facing portion 424, and the step shaft 8 And the link plate 31 are removed from the positioning tool 41 (positioning tool removing step). In this way, step 2 is assembled.
　このようなステップ２の製造方法では、位置決め具配置工程において、ステップ軸８とリンクプレート３１との間の隙間１２に第１の対向部４２３及び第２の対向部４２４のそれぞれを差し込んだ状態で、ばね４３の弾性復元力により位置決め具本体４２をリンクプレート３１に押し付けるので、実施の形態１と同様の効果が得られるとともに、第１の対向部４２３及び第２の対向部４２４のそれぞれを隙間１２に差し込むだけで、リンクプレート３１に位置決め具本体４２をばね４３の弾性復元力によって自動的に押し付けることができる。これにより、リンクプレート３１とステップ本体１１との間に位置決め具２１を配置するときの作業効率を向上させることができる。 In such a manufacturing method of Step 2, in the positioning tool arranging step, the first facing portion 423 and the second facing portion 424 are inserted into the gap 12 between the step shaft 8 and the link plate 31, respectively. Since the positioning tool main body 42 is pressed against the link plate 31 by the elastic restoring force of the spring 43, the same effect as in the first embodiment can be obtained, and each of the first facing portion 423 and the second facing portion 424 can be separated by a gap. 12, the positioning tool main body 42 can be automatically pressed against the link plate 31 by the elastic restoring force of the spring 43. Thereby, the working efficiency when the positioning tool 21 is disposed between the link plate 31 and the step body 11 can be improved.
　なお、上記の例では、第１の対向部４２３及び第２の対向部４２４のそれぞれがテーパ部になっているが、第１の対向部４２３のみがテーパ部になっていてもよいし、第２の対向部４２４のみがテーパ部になっていてもよい。即ち、第１の対向部４２３及び第２の対向部４２４の少なくともいずれかがテーパ部になっていればよい。 In the above example, each of the first facing portion 423 and the second facing portion 424 is a tapered portion, but only the first facing portion 423 may be a tapered portion. Only the two facing portions 424 may be tapered. That is, at least one of the first facing portion 423 and the second facing portion 424 only needs to be a tapered portion.

The amount of protrusion of the holding screw 54 from the facing piece 531 can be adjusted by turning the holding screw 54. The distance between the front end portion of the holding screw 54 and the first reference surface 521 changes according to the change in the protruding amount of the holding screw 54. Other configurations are the same as those in the first embodiment.

　次に、ステップ２を組み立てるときの手順について説明する。スリーブ９を介してステップ本体１１をステップ軸８に連結するまでの手順は、実施の形態１と同様である。スリーブ９を介してステップ本体１１をステップ軸８に連結した後、位置決め具６１を用いて、ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行う。 Next, the procedure for assembling Step 2 will be described. The procedure until the step body 11 is connected to the step shaft 8 via the sleeve 9 is the same as that of the first embodiment. After the step body 11 is connected to the step shaft 8 via the sleeve 9, the step body 11 is positioned with respect to the step shaft 8 in the axial direction of the step shaft 8 using the positioning tool 61.
　ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行うときには、まず、図１３に示すように、リンクプレート３１とステップ本体１１との間に位置決め具本体６２を配置し、位置決め具本体６２をリンクプレート３１に接触させる（位置決め具配置工程）。 When positioning the step body 11 with respect to the step shaft 8 in the axial direction of the step shaft 8, first, as shown in FIG. 13, a positioning tool body 62 is arranged between the link plate 31 and the step body 11, and the positioning tool The main body 62 is brought into contact with the link plate 31 (positioning tool arranging step).
　位置決め具配置工程では、図１４に示すように、第１の基準面６２１をリンクプレート３１に向け、第２の基準面６２２をステップ本体１１に向けた状態で位置決め具本体６２を配置する。また、位置決め具配置工程では、板ばね６３と第１の基準面６２１との間にリンクプレート３１を板ばね６３の他端部から差し込む。板ばね６３と第１の基準面６２１との間にリンクプレート３１を差し込むと、板ばね６３の弾性復元力によって板ばね６３と第１の基準面６２１との間でリンクプレート３１が把持され、第１の基準面６２１がリンクプレート３１に押し付けられる。これにより、位置決め具６１がリンクプレート３１に保持される。 In the positioning tool arranging step, as shown in FIG. 14, the positioning tool body 62 is placed with the first reference surface 621 facing the link plate 31 and the second reference surface 622 facing the step body 11. In the positioning tool arranging step, the link plate 31 is inserted from the other end of the plate spring 63 between the plate spring 63 and the first reference surface 621. When the link plate 31 is inserted between the leaf spring 63 and the first reference surface 621, the link plate 31 is gripped between the leaf spring 63 and the first reference surface 621 by the elastic restoring force of the leaf spring 63, The first reference surface 621 is pressed against the link plate 31. Thereby, the positioning tool 61 is held by the link plate 31.
　位置決め具配置工程の後のステップ本***置決め工程、スリーブ位置決め工程、スリーブ固定工程は、実施の形態１と同様である。 The step body positioning process, sleeve positioning process, and sleeve fixing process after the positioning tool arranging process are the same as those in the first embodiment.
　スリーブ固定工程の後、リンクプレート３１に対して位置決め具６１を第１の基準面６２１に沿ってスライドさせながら、第１の基準面６２１と板ばね６３との間からリンクプレート３１を抜いて、位置決め具６１をリンクプレート３１から外す（位置決め具取り外し工程）。このようにして、ステップ２が組み立てられる。 After the sleeve fixing step, the link plate 31 is removed from between the first reference surface 621 and the leaf spring 63 while sliding the positioning tool 61 along the first reference surface 621 with respect to the link plate 31. The positioning tool 61 is removed from the link plate 31 (positioning tool removing step). In this way, step 2 is assembled.
　このようなステップ２の製造方法では、位置決め具配置工程において、位置決め具本体６２と板ばね６３との間にリンクプレート３１を差し込んだ状態で、板ばね６３の弾性復元力により位置決め具本体６２をリンクプレート３１に押し付けるので、実施の形態３と同様の効果が得られるとともに、位置決め具本体６２と板ばね６３との間にリンクプレート３１を差し込むだけで、リンクプレート３１に位置決め具本体６２を自動的に押し付けることができる。これにより、リンクプレート３１とステップ本体１１との間に位置決め具２１を配置するときの作業効率を向上させることができる。 In such a manufacturing method of Step 2, in the positioning tool arranging step, the positioning tool body 62 is moved by the elastic restoring force of the leaf spring 63 with the link plate 31 inserted between the positioning tool body 62 and the leaf spring 63. Since it is pressed against the link plate 31, the same effects as those of the third embodiment can be obtained, and the positioning tool body 62 can be automatically inserted into the link plate 31 simply by inserting the link plate 31 between the positioning tool body 62 and the leaf spring 63. Can be pressed. Thereby, the working efficiency when the positioning tool 21 is disposed between the link plate 31 and the step body 11 can be improved.

　図２４は、この発明の実施の形態９によるエスカレータのステップ本体１１の位置決めを行っているときの状態を示す模式的な一部断面図である。本実施の形態では、ステップ軸８に対するステップ本体１１の位置決めを行うときに、位置決め具８１がガイドパッド用ボス部７２１に取り付けられる。位置決め具８１の構成は、実施の形態７と同様である。他の構成は実施の形態５と同様である。 Embodiment 9 FIG.
FIG. 24 is a schematic partial cross-sectional view showing a state when positioning of the step body 11 of the escalator according to the ninth embodiment of the present invention. In the present embodiment, the positioning tool 81 is attached to the guide pad boss 721 when positioning the step body 11 with respect to the step shaft 8. The configuration of the positioning tool 81 is the same as that of the seventh embodiment. Other configurations are the same as those of the fifth embodiment.
　次に、ステップ２を組み立てるときの手順について説明する。ステップ２を組み立てるときには、実施の形態１と同様にして、スリーブ９を介してステップ本体１１をステップ軸８に連結する。この後、実施の形態１と同様の位置決め具８１を用いて、ステップ軸８に対するステップ本体１１の位置決めをステップ軸８の軸線方向について行う。 Next, the procedure for assembling Step 2 will be described. When the step 2 is assembled, the step body 11 is connected to the step shaft 8 through the sleeve 9 in the same manner as in the first embodiment. Thereafter, the positioning of the step body 11 with respect to the step shaft 8 is performed in the axial direction of the step shaft 8 using the same positioning tool 81 as in the first embodiment.
　ステップ軸８に対するステップ本体１１の位置決めを行うときには、まず、ガイドパッド７２２をガイドパッド用ボス部７２１から外してガイドパッド用ボス部７２１の端面７２５を露出させておく。この後、リンクプレート３１とガイドパッド用ボス部７２１との間に位置決め具８１を配置するとともに、溝部８４の開放部から溝部８４内にステップ軸８を挿入する。また、位置決め具８１を取付具８３によってガイドパッド用ボス部７２１に取り付ける。このとき、位置決め具本体８２の第２の基準面２２５にガイドパッド用ボス部７２１の端面７２５を接触させる（位置決め具配置工程）。 When positioning the step body 11 with respect to the step shaft 8, first, the guide pad 722 is removed from the guide pad boss 721 to expose the end surface 725 of the guide pad boss 721. Thereafter, the positioning tool 81 is disposed between the link plate 31 and the guide pad boss 721, and the step shaft 8 is inserted into the groove 84 from the opening of the groove 84. Further, the positioning tool 81 is attached to the guide pad boss portion 721 by the attachment tool 83. At this time, the end surface 725 of the guide pad boss 721 is brought into contact with the second reference surface 225 of the positioning tool main body 82 (positioning tool arranging step).
　位置決め具配置工程の後、ステップ軸８に対して位置決め具８１をステップ本体１１及びガイドパッド装置７２とともにスライドさせて、リンクプレート３１に位置決め具８１の第１の基準面２２４を接触させる。これにより、ステップ軸８に対するステップ本体１１の位置決めがステップ軸８の軸線方向について行われる（ステップ本***置決め工程）。この後の手順は、実施の形態１と同様である。 After the positioning tool arranging step, the positioning tool 81 is slid along with the step body 11 and the guide pad device 72 with respect to the step shaft 8 to bring the first reference surface 224 of the positioning tool 81 into contact with the link plate 31. Thereby, the positioning of the step body 11 with respect to the step shaft 8 is performed in the axial direction of the step shaft 8 (step body positioning step). The subsequent procedure is the same as in the first embodiment.
　このようなステップ２の製造方法では、リンクプレート３１とステップ本体１１との間に配置した位置決め具本体８２をガイドパッド用ボス部７２１に取り付けるとともに、位置決め具本体８２をリンクプレート３１に接触させるので、実施の形態１と同様に、ステップ軸８に対するステップ本体１１の位置決めを容易にすることができ、部品コストの削減を図ることができる。また、リンクプレート３１からガイドパッド用ボス部７２１までの距離がステップ２ごとにばらついてしまうことを防止することができ、ステップ軸８に対するステップ本体１１の位置決め精度を向上させることができる。これにより、ステップ本体１１とスカートガード７１との間の隙間をより確実に確保することができる。 In such a manufacturing method of Step 2, the positioning tool main body 82 disposed between the link plate 31 and the step main body 11 is attached to the guide pad boss 721, and the positioning tool main body 82 is brought into contact with the link plate 31. As in the first embodiment, the positioning of the step body 11 with respect to the step shaft 8 can be facilitated, and the cost of parts can be reduced. Further, it is possible to prevent the distance from the link plate 31 to the guide pad boss 721 from being varied every step 2, and the positioning accuracy of the step body 11 with respect to the step shaft 8 can be improved. Thereby, the clearance gap between the step main body 11 and the skirt guard 71 can be ensured more reliably.
