Abstract
Description
この発明は、エスカレーター等乗客コンベアに用いられる組立て式踏段に関するものである。 The present invention relates to an assembly-type step used for a passenger conveyor such as an escalator.
従来の一般的なエスカレーターの踏段10は、図7に示すように、踏板部10aおよびライザー部10bと、踏板部10aおよびライザー部10bを支持する左右一対のブラケット部10cと、踏板部10aの裏面に取り付けられた軸11と、ブラケット部10cに取り付けられた追従ローラ12とから構成されている。このような踏段10は、軸11の左右両端にチェーンを介して駆動機に連結され、駆動機からの動力がチェーンを通して軸11に伝達され、踏段10が前後に駆動されることになる。なお、追従ローラ12は、踏段10が移動する際レール上を転がることにより踏段10の駆動を円滑にする役割がある。 As shown in FIG. 7, a conventional general escalator step 10 includes a tread plate portion 10a and a riser portion 10b, a pair of left and right bracket portions 10c that support the tread plate portion 10a and the riser portion 10b, and the back surface of the tread plate portion 10a. The shaft 11 is attached to the bracket portion 10 and the follower roller 12 is attached to the bracket portion 10c. Such a step 10 is connected to the drive machine through a chain at both the left and right ends of the shaft 11, power from the drive machine is transmitted to the shaft 11 through the chain, and the step 10 is driven back and forth. The follower roller 12 has a role of smoothly driving the step 10 by rolling on the rail when the step 10 moves.
この踏段10の材質は、通常ステンレス又はアルミ合金製であり、アルミ合金で構成される踏段の場合、一般的にはダイカスト法にて一体で鋳造され、仕上げ加工を行うことにより製造されている。 The material of the step 10 is usually made of stainless steel or an aluminum alloy, and in the case of a step made of an aluminum alloy, it is generally manufactured by casting integrally by a die casting method and performing a finishing process.
この踏板部10a、ライザー部10b、ブラケット部10cを一体で鋳造、仕上げ加工をする場合、踏段10は大きいもので幅が1000mmあるため、鋳造することが可能なダイカストマシンは限られ、幅1000mmの踏段の場合、一般的には型締め力3000ton以上の大
型ダイカストマシンが必要となり、そのマシン取得に過大な費用を必要とする。
When the step plate portion 10a, the riser portion 10b, and the bracket portion 10c are integrally cast and finished, since the step 10 is large and has a width of 1000 mm, die casting machines that can be cast are limited, and the width is 1000 mm. In the case of steps, a large die-casting machine with a clamping force of 3000 tons or more is generally required, and excessive costs are required to acquire the machine.
また、踏板部10a、ライザー部10b、ブラケット部10cを各々部品単位で鋳造して仕上げ加工を行い、締結する組み立て式のものがあるが、この場合、完成品としての精度を一体式と同程度にするため、各構成部品には一体式のものよりも高い精度が必要とされる。また、踏板部10a、ライザー部10bは平板形状をしているために、鋳造時の温度分布や収縮度合いが場所によって異なり、これが原因で歪み易く、この結果、組付け時のライザー部10bと踏板部10aとの間に隙間ができるといった外観上の問題や完成品の寸法不具合等の問題が発生することになる。 In addition, there is an assembly type in which the tread plate portion 10a, the riser portion 10b, and the bracket portion 10c are each casted into parts and finished and then fastened. In this case, the accuracy of the finished product is about the same as that of the integrated type. Therefore, each component is required to have higher accuracy than a single component. Further, since the tread plate portion 10a and the riser portion 10b have a flat plate shape, the temperature distribution and shrinkage degree at the time of casting differ depending on the location, and this is easily distorted. As a result, the riser portion 10b and the tread plate at the time of assembly Problems such as an appearance problem such as a gap between the part 10a and a dimensional defect of the finished product may occur.
このような問題点を解消するものとして、図8に示すように、踏段10を幅方向に3分割し、左側分割踏段1a、中央分割踏段1b、右側分割踏段1cを組み合わせて構成するものも提案されている。(特許文献1)
図8において、分割踏段1a、1b、1cは、それぞれ踏板部2a、2b、2cと、ライザー部3a、3b、3cと、踏板部2a、2b、2cおよびライザー部3a、3b、3cに設けられた連結部4a、4b、4c、5a、5b、5cとを有し、ライザー部3a、3b、3cの各連結部4a、4b、4c間をボルトにより締結するとともに、踏板部2a、2b、2cの各連結部5a、5b、5cを補強リブ6によってボルト締結し、踏段10を構成することになる。
In order to solve such a problem, as shown in FIG. 8, a configuration is also proposed in which the step 10 is divided into three in the width direction, and the left divided step 1a, the central divided step 1b, and the right divided step 1c are combined. Has been. (Patent Document 1)
In FIG. 8, the divided steps 1a, 1b, 1c are respectively provided in the step plates 2a, 2b, 2c, the risers 3a, 3b, 3c, the step plates 2a, 2b, 2c and the risers 3a, 3b, 3c. Connecting portions 4a, 4b, 4c, 5a, 5b, and 5c, and connecting the connecting portions 4a, 4b, and 4c of the risers 3a, 3b, and 3c with bolts and the tread plate portions 2a, 2b, and 2c. The connecting portions 5a, 5b, and 5c are bolted by the reinforcing rib 6 to constitute the step 10.
しかしながら、このような特許文献1の組立て式踏段10の場合、ダイカストマシンの小型化、製造の容易化が可能となるが、組立て式踏段10のライザー部3a、3b、3c側面に設けられた各連結部4a、4b、4cをボルトで締結するため、踏板部2a、2b、2cの反ライザー側に下方向に荷重がかかった場合、このライザー側の連結ボルトにせん断応力がかかり、連結ボス部にも引張り方向に大きな応力集中が生じることになり、結果としてボルトや連結部位の疲労破壊など、乗客コンベアの不具合に繋がる可能性がある。 However, in the case of such an assembly-type step 10 of Patent Document 1, it is possible to reduce the size and manufacture of the die casting machine. However, each of the steps provided on the side surfaces of the risers 3a, 3b, and 3c of the assembly-type step 10 is possible. Since the connecting portions 4a, 4b, and 4c are fastened with bolts, when a load is applied downward on the anti-riser side of the tread plate portions 2a, 2b, and 2c, a shearing stress is applied to the connecting bolt on the riser side, and the connecting boss portion In addition, a large stress concentration occurs in the pulling direction, and as a result, there is a possibility that it may lead to a failure of the passenger conveyor such as fatigue failure of bolts and connection parts.
この発明による乗客コンベアの踏段は、踏板部、ライザー部を一体とし、幅方向に分割された複数の分割踏段を連結して組み立てる乗客コンベアの踏段であって、分割踏段におけるそれぞれの対向する踏板部の裏面に、互いに連結するためのボス部と、裏面から側面側に突出したL字状のアングル部とを設け、複数の分割踏段を幅方向に寄せて、一方の分割階段のボス部上に他方の分割踏段のL字状アングル部を重ね合わせて連結固定することを特徴としたものである。 A step of a passenger conveyor according to the present invention is a step of a passenger conveyor in which a step plate portion and a riser portion are integrated, and a plurality of divided steps divided in the width direction are connected and assembled, each step plate portion facing each other in the divided steps A boss portion for connecting to each other and an L-shaped angle portion projecting from the back surface to the side surface are provided on the back surface of each of the two, and a plurality of divided steps are moved in the width direction on the boss portion of one divided step The L-shaped angle part of the other divided step is overlapped and connected and fixed.
この発明によれば、踏板部裏面に側面から突出したL字状のアングル部を設け、このアングル部を用いて隣接する踏板部と締結することによって、踏板部を締結するボルトにせん断方向の応力や連結部に引張り方向の応力集中を生じさせることがなく、分割踏段を組み立てて構成した乗客コンベアの不具合を回避させることが可能となる。 According to the present invention, an L-shaped angle portion projecting from the side surface is provided on the back surface of the tread portion, and by using this angle portion to fasten the adjacent tread portion, stress in the shear direction is applied to the bolt that fastens the tread portion. In addition, it is possible to avoid the trouble of the passenger conveyor constructed by assembling the divided steps without causing stress concentration in the pulling direction at the connecting portion.
実施の形態1.
以下、この発明の実施の形態1に係る乗客コンベアの組立て式踏段を図に基づいて説明する。
図1は、この発明の実施の形態1による乗客コンベアの組立て式踏段を踏段裏面から見た斜視図である。図において、踏段10は、それぞれ幅200mmに形成された左側の分割
踏段1a、中央の分割踏段1b、右側の分割踏段1cとから構成されており、例えば、1000mmの踏段10を製造する場合、左右分割踏段1a、1cの間に中央分割踏段1bを3枚並べて連結させ、同様に幅800mmの場合は、中央分割踏段1bを2枚、幅600mmの場合は、中央分割踏段1bを1枚、間に設置して連結することにより幅の異なる乗客コンベアの製造に対応することが可能となる。
Embodiment 1 FIG.
Hereinafter, the assembly type step of the passenger conveyor which concerns on Embodiment 1 of this invention is demonstrated based on figures.
FIG. 1 is a perspective view of an assembled step of a passenger conveyor according to Embodiment 1 of the present invention as seen from the back of the step. In the figure, the step 10 is composed of a left divided step 1a, a central divided step 1b, and a right divided step 1c each formed to have a width of 200 mm. For example, when manufacturing a 1000 mm step 10, Three central divided steps 1b are connected to each other between the divided steps 1a and 1c. Similarly, when the width is 800 mm, two central divided steps 1b are used. When the width is 600 mm, one central divided step 1b is provided between the divided steps 1a and 1c. It becomes possible to respond to the manufacture of passenger conveyors having different widths by installing and connecting them.
このような踏段10の組立ては、次のような構成により達成される。
すなわち、左側の分割踏段1aには、踏板部2aの裏面に形成されたねじ穴を有するボス2aaと、踏板部2aの前後において側面から突出する一対のL字状アングル2abと、一対のアングル2ab間に配置され、固定用のボルト穴を有するボス2acとが形成されている。なお、一対のL字状アングル2abの長さの和は、ボス2acの長さとほぼ等しく形成され、かつ、L字状アングル2abの一方と、ボス2acには、それぞれ位置決め用のキリ穴が設けられている。
Such assembly of the step 10 is achieved by the following configuration.
That is, the left divided step 1a includes a boss 2aa having a screw hole formed on the back surface of the tread portion 2a, a pair of L-shaped angles 2ab projecting from the side surfaces before and after the tread portion 2a, and a pair of angles 2ab. A boss 2ac having a bolt hole for fixing is formed therebetween. The sum of the lengths of the pair of L-shaped angles 2ab is formed substantially equal to the length of the boss 2ac, and one of the L-shaped angles 2ab and the boss 2ac are each provided with a positioning hole. It has been.
また、右側の分割踏段1cには、左側の分割踏段1aに対応する踏板部2aの位置に形成されたねじ穴を有するボス2caと、踏板部2aのL字状アングル2abに対応するボス2cbと、ボス2acに対応するL字状アングル2ccが形成され、それぞれアングル2abおよびボス2acに対応する位置にキリ穴が設けられている。
さらに、中央の分割踏段1bには、左右の分割踏段1a、1cに対応する位置に一対のボス2baと、分割踏段1a、1cのL字状アングル2ab、2ccを受けるボス2bbと、踏板部2bの両側面から突出し、分割踏段1a、1cのボス2ac、2cbに重ね合されるL字状アングル2bcとが形成されている。
Further, the right divided step 1c includes a boss 2ca having a screw hole formed at the position of the step plate portion 2a corresponding to the left divided step 1a, and a boss 2cb corresponding to the L-shaped angle 2ab of the step plate portion 2a. The L-shaped angle 2cc corresponding to the boss 2ac is formed, and a drill hole is provided at a position corresponding to the angle 2ab and the boss 2ac, respectively.
Further, the central divided step 1b includes a pair of bosses 2ba at positions corresponding to the left and right divided steps 1a and 1c, a boss 2bb that receives the L-shaped angles 2ab and 2cc of the divided steps 1a and 1c, and a step plate portion 2b. L-shaped angle 2bc which protrudes from the both side surfaces and overlaps with the bosses 2ac and 2cb of the divided steps 1a and 1c is formed.
このような構成のもとで、分割踏段1aのアングル2ab、ボス2acと分割踏段1bのアングル2bc、ボス2bbとを重ね合わせるとともに、分割踏段1bのボス2bb、アングル2bcと分割踏段1cのアングル2cc、ボス2cbとを重ね合わせ、それぞれのキリ穴にピン7を挿入して位置合せを行い、ボルト8により各分割踏段1a、1b、1cを仮固定する。最後にアングル材6を用いてボルト8をボス2aa、2ba、2caに締め付けることにより各分割踏段1a、1b、1cを固定補強し、踏段10を構成することになる。 Under such a configuration, the angle 2ab and the boss 2ac of the divided step 1a are overlapped with the angle 2bc and the boss 2bb of the divided step 1b, and the boss 2bb, the angle 2bc and the angle 2cc of the divided step 1c are overlapped. The bosses 2cb are overlapped with each other, the pins 7 are inserted into the respective drill holes for alignment, and the divided steps 1a, 1b, 1c are temporarily fixed by the bolts 8. Finally, the angle member 6 is used to fasten the bolt 8 to the bosses 2aa, 2ba, and 2ca, thereby fixing and reinforcing the divided steps 1a, 1b, and 1c, thereby forming the step 10.
ここで、ボス2acおよびアングル2bcのボルト穴およびピン穴の穴位置は、アングル2abやボス2bbのピン穴の位置に対してなるべく離す一方、これらの穴の加工時に加工機のスピンドルが分割踏段1a、1bのライザー部3a、3bに干渉しない位置に形成されている。このようにボルト穴およびピン穴を配置することによって、締結用のボルト穴や位置決めピン穴を加工する場合、ワークの姿勢を変える必要がなく、1チャックで加工できるため、回転する治具を備えた加工設備を必要とせず、2工程に分ける必要もないので、加工設備が比較的安価で済み、且つ高い穴位置精度も確保することができる。 Here, the hole positions of the bolt holes and pin holes of the boss 2ac and the angle 2bc are separated as much as possible from the positions of the pin holes of the angle 2ab and the boss 2bb, while the spindle of the processing machine is divided into the divided steps 1a when machining these holes. It is formed at a position where it does not interfere with the risers 3a and 3b of 1b. By arranging bolt holes and pin holes in this way, when machining fastening bolt holes and positioning pin holes, there is no need to change the posture of the workpiece, and it can be processed with one chuck, so a rotating jig is provided. Therefore, the processing equipment is relatively inexpensive and high hole position accuracy can be ensured.
なお、左右の分割踏段1a、1cには、踏板部2a、2cとライザー部3a、3cを三角形状に支持するブラケット9が設けられており、これにより組立て式踏段10全体の強度を補強することが可能となる。
また、ボス2aa、2ba、2caの座面は、アングル2ab、2bcよりもやや高く形成されており、アングル材6の取付に影響を及ぼすことがない。
The left and right divided steps 1a and 1c are provided with brackets 9 that support the step plates 2a and 2c and the risers 3a and 3c in a triangular shape, thereby reinforcing the strength of the entire assembly-type step 10. Is possible.
Further, the seating surfaces of the bosses 2aa, 2ba, and 2ca are formed slightly higher than the angles 2ab and 2bc, and the attachment of the angle member 6 is not affected.
このように各分割踏段1a、1b、1cに、端面の長手方向に向かってアングル形状とボス形状を交互に設け、対向する各分割踏段1a、1b、1cのアングル形状とボス形状とを重ね合わせて締結することにより、一つの分割踏段に荷重がかかったとき、相手側の分割踏段にはボス形状からアングル形状に力が加わるが、アングル形状からボス形状に力が伝わらないことになり、どの分割踏段に荷重がかかっても両側の分割踏段に力が伝わり、荷重がかかった分割踏段を両側の分割踏段で支えるようにすることが可能となる。 In this way, each divided step 1a, 1b, 1c is alternately provided with an angle shape and a boss shape in the longitudinal direction of the end face, and the angle shape and the boss shape of each of the opposed divided steps 1a, 1b, 1c are overlapped. When a load is applied to one split step, force is applied to the other split step from the boss shape to the angle shape, but no force is transmitted from the angle shape to the boss shape. Even when a load is applied to the divided steps, force is transmitted to the divided steps on both sides, and the divided steps on which the load is applied can be supported by the divided steps on both sides.
また、例えば、隣り合う分割踏段1aと分割踏段1bを幅方向に寄せ合うと、ボス2acの上にアングル2bcが重なることになり、2箇所の位置決めピン用の穴にピン7を挿入することによって踏段同士の位置が決まり、踏段10の組立ての効率化を図ることができる。この点は分割踏段1bと分割踏段1cの組立て、あるいは中央の分割踏段1bの枚数が増加しても同様に組立てを行なうことが可能である。 Further, for example, when the adjacent divided steps 1a and 1b are brought close to each other in the width direction, the angle 2bc overlaps the boss 2ac, and the pins 7 are inserted into the holes for positioning pins at two locations. The positions of the steps are determined, and the assembly efficiency of the steps 10 can be improved. In this regard, the divided steps 1b and 1c can be assembled, or can be similarly assembled even if the number of central divided steps 1b is increased.
ところで、ダイカスト法によって鋳造される分割踏段は、その表面を固定金型で、裏面を可動金型で形成されることになるが、一般に固定金型と可動金型の境界となる部位には
バリが発生することが知られており、連結する分割踏段の双方の側面あるいはボルト座にバリがあると、組付け時の効率悪化、組付け寸法精度への悪影響等があるため、バリ除去加工が必要となってくる。
By the way, the divided steps cast by the die casting method are formed with a fixed mold on the front surface and a movable mold on the back surface. Generally, however, there is a varistor at the boundary between the fixed mold and the movable mold. If there are burrs on both sides or bolt seats of the divided steps to be connected, the efficiency during assembly will be adversely affected and the dimensional accuracy will be adversely affected. It becomes necessary.
この発明においては、固定金型と可動金型の境界(以降「見切り」と称する)をアングル形状部位においては、図2の太線で示すようにL字状アングル2bcの座面の縁に沿って設け、また、座面の寸法を、組付け時に相手側となる分割踏段2acのボルト座面より大きく形成している。このように構成することによって、図3に黒丸で示すようにバリが締結部位に挟まれないようにすることが可能となり、バリ取り工程を省略することができる。 In the present invention, the boundary between the fixed mold and the movable mold (hereinafter referred to as “parting”) is formed along the edge of the seating surface of the L-shaped angle 2bc as shown by the thick line in FIG. In addition, the size of the seating surface is formed larger than the bolt seating surface of the split step 2ac that is the counterpart when assembled. By configuring in this way, it becomes possible to prevent the burrs from being sandwiched between the fastening parts as shown by the black circles in FIG. 3, and the deburring step can be omitted.
また、ライザー部においては、図4に示すように一方の分割踏段のクリート底面を形成する面より相手側にアングル形状3caを突出させ、相手側分割踏段におけるライザー側の見切り部をライザークリート付け根付近に設ける。これによって組付け時、ライザー端面に黒丸で示すようにバリが干渉せず、組付け寸法精度に影響を及ぼすことがない。
さらに、組付けた状態ではアングル形状3caが潜り込み、相手側分割踏段のライザー3b裏面と重なり合う形となるので、大きな荷重がかかる分割踏段と、他の分割踏段との間に変形量の差からライザー部位の境界に隙間が生じても隙間を目立たなくすることができる。
Further, in the riser portion, as shown in FIG. 4, the angle shape 3ca protrudes from the surface forming the cleat bottom surface of one divided step to the other side, and the parting portion on the riser side in the other divided step is near the root of the riser cleat. Provided. As a result, during assembly, as shown by black circles on the riser end face, burrs do not interfere and the assembly dimensional accuracy is not affected.
Further, in the assembled state, the angle shape 3ca sinks and overlaps with the rear surface of the riser 3b of the other divided step, so the riser rises from the difference in deformation amount between the divided step where a large load is applied and the other divided steps. Even if a gap occurs at the boundary between the parts, the gap can be made inconspicuous.
実施の形態2.
実施の形態1においては、ライザー部3a、3b、3cに締結する部位を持たないため、ライザークリート面に荷重がかかると変形しやすく、特に分割踏段の境界付近に負荷がかかった場合、変形して隙間が生じる可能性がある。
図5はこのような不具合を防止するもので、ライザー部3a、3bの裏面に側面から突き出た補強ブラケット3aa、3baを対向する他方と段違いとなるように構成したものである。
このように構成することによって、ブラケット3aa、3baが互いに相手側のライザー部3b、3aの裏面を支えるようになり、ブラケット形状を通じて負荷がかかったライザー部に対して隣接する分割踏段に負荷が分散され、ライザー部の剛性を確保することができる。
Embodiment 2. FIG.
In the first embodiment, since there is no portion to be fastened to the risers 3a, 3b, 3c, it is easily deformed when a load is applied to the riser cleat surface, particularly when a load is applied near the boundary of the divided steps. May cause gaps.
FIG. 5 is intended to prevent such a problem, and is configured such that the reinforcing brackets 3aa and 3ba protruding from the side surfaces on the back surfaces of the risers 3a and 3b are different from the other facing one another.
With this configuration, the brackets 3aa and 3ba support the back surfaces of the mating risers 3b and 3a, and the load is distributed to the divided steps adjacent to the loaded riser through the bracket shape. Thus, the rigidity of the riser portion can be ensured.
実施の形態3.
図6はこの発明の実施の形態3を示すもので、図において、踏板2bとライザー3bの裏面中央部にリブ2bdを設けるとともに、両端部にそれぞれリブ2beを設けたものである。
ダイカスト鋳造においては、一般的に凝固、冷却過程において鋳造素材が収縮することが知られており、ライザー部3bと踏板2bとの間の角度が縮まるような収縮をし、かつ、中央部と端面部の収縮量に差が生じて歪んだ形状となる可能性があり、さらに収縮量もワークによってばらつくために連結後にライザー間に段差が生じる恐れが生じることになるが、踏板2bとライザー部3bの境界部付近にリブ2bd、2beを設けることによって収縮時に互いに支えることが可能となり、踏段10における歪みの発生を防止することができる。
Embodiment 3 FIG.
FIG. 6 shows Embodiment 3 of the present invention. In the figure, ribs 2bd are provided at the center of the back surface of the tread 2b and the riser 3b, and ribs 2be are provided at both ends.
In die casting, it is generally known that the casting material shrinks during the solidification and cooling process, shrinks so that the angle between the riser part 3b and the tread 2b is reduced, and the center part and the end face There is a possibility that a difference occurs in the amount of contraction of the parts, resulting in a distorted shape. Further, since the amount of contraction also varies depending on the work, there is a possibility that a step will be generated between the risers after connection, but the step board 2b and the riser part 3b By providing the ribs 2bd and 2be in the vicinity of the boundary portion, it becomes possible to support each other at the time of contraction, and the occurrence of distortion in the step 10 can be prevented.
以上のように、この発明によれば、踏板部を締結するボルトにせん断方向の応力や連結部に引張り方向の応力集中を生じさせることがなく、乗客コンベアの踏段として分割踏段を組み立てて構成したものを実用化させることが可能となる。
なお、この発明は、その発明の範囲内において、実施の形態を適宜、変形、省略することが可能である。

Things can be put to practical use.
In the present invention, the embodiments can be appropriately modified and omitted within the scope of the invention.
