Description
本発明は、乗りかごまたは釣り合い重りから成る昇降体を上下方向に案内するガイドレールに、潤滑油を供給するエレベータの給油装置及びエレベータの給油方法に関する。 The present invention relates to an elevator oil supply apparatus and an elevator oil supply method for supplying lubricating oil to a guide rail that vertically guides a lifting body composed of a car or a counterweight.
エレベータの乗りかごまたは釣り合い重りから成る昇降体には、昇降路内に立設されたガイドレールの軌道に沿って当該昇降体を走行させる案内装置としてガイドシューが設けられている。このガイドシューは、ガイドレール上を摺動することから摺動時に発生する振動等がエレベータの乗り心地に影響する。そのために、従来のエレベータにあっては潤滑油供給装置を常設し、ガイドレールに常に潤滑油を供給することでガイドレールに対する昇降体の摺動を円滑にしていた。また、それと同時にガイドレールに対する防錆効果も得ていた。 An elevator body composed of an elevator car or a counterweight is provided with a guide shoe as a guide device for causing the elevator body to travel along a track of a guide rail standing in the hoistway. Since this guide shoe slides on the guide rail, vibrations and the like generated during sliding affect the riding comfort of the elevator. For this reason, in conventional elevators, a lubricating oil supply device is always installed, and the lubricating oil is always supplied to the guide rail, so that the lifting body slides smoothly with respect to the guide rail. At the same time, the antirust effect on the guide rail was also obtained.
ところが、上述した構成の従来技術では、潤滑油を補充する手間や、潤滑油が飛散して昇降路及び乗りかご等の昇降体を潤滑油で汚損させてしまう等の問題があった。このようなことから従来、特許文献１に、ガイドシューを含油樹脂等で構成し、ガイドシュー自体の潤滑性を向上させて、潤滑油の常時供給を不要とすることができるオイルシューが提案されている。 However, in the conventional technology having the above-described configuration, there are problems such as the trouble of replenishing the lubricating oil, and the lubricating oil scatters and the hoistway such as the hoistway and the car is contaminated with the lubricating oil. For this reason, conventionally, Patent Document 1 proposes an oil shoe in which the guide shoe is made of oil-impregnated resin and the like, which improves the lubricity of the guide shoe itself and eliminates the need for constant supply of lubricating oil. ing.
特許文献１に示されるオイルレスシューをガイドシューとした場合には、ガイドシューとガイドレールの摺動面との接触部分に対しては微量の油分が付着してオイルレスシューの摺動を円滑にしつつ防錆効果も得られる。しかし、オイルレスシューとガイドレールの摺動面との接触部分以外の部分には油分が付着しないため、それらの部分に錆が発生し、昇降路内の美観を損ねてしまう問題がある。また、ガイドレールから錆が剥がれ落ちてオイルレスシューとガイドレールの摺動面との間に入り込み、オイルレスシュー及びガイドレールの摩耗を促進させる虞があり、また、剥がれ落ちた錆が昇降路内の各機器に入り込み、該当する機器の劣化や故障を引き起こす虞があった。 When the oilless shoe disclosed in Patent Document 1 is used as a guide shoe, a small amount of oil adheres to the contact portion between the guide shoe and the sliding surface of the guide rail, so that the oilless shoe slides smoothly. In addition, a rust prevention effect can be obtained. However, since oil does not adhere to portions other than the contact portion between the oilless shoe and the sliding surface of the guide rail, there is a problem that rust is generated in those portions and the aesthetic appearance in the hoistway is impaired. In addition, rust may fall off from the guide rail and may enter between the oilless shoe and the sliding surface of the guide rail, which may promote wear of the oilless shoe and guide rail. There is a risk that it will enter each device and cause deterioration or failure of the corresponding device.
このようなことから、ガイドシューとしてオイルレスシューを設けるようにしたエレベータにあっては、所定期間毎に、例えば数年毎に防錆効果のある潤滑油を塗布することが必要になる。この塗布作業は、潤滑油を染み込ませたウェスを人手でガイドレールに擦りつけるようにして行っている。したがって、作業効率の向上を見込めないものであった。なお、オイルレスシューを備えたエレベータにあって、前述のような人手による塗布作業に代えて、従来から用いられている前述の潤滑油供給装置を昇降体に取り付け、昇降体を昇降させて潤滑油供給装置の油をガイドレールに自動的に供給してガイドレールの摺動面以外の部分も含めて塗布することが考えられる。しかし、このように潤滑油供給装置を設けることは設備コスト、設置コストが増加し、実用性の点で問題がある。 For this reason, in an elevator in which an oilless shoe is provided as a guide shoe, it is necessary to apply lubricating oil having a rust-preventing effect every predetermined period, for example, every few years. This coating operation is performed by manually rubbing the cloth soaked with lubricating oil against the guide rail. Therefore, improvement in work efficiency cannot be expected. In addition, in an elevator equipped with an oilless shoe, instead of the above-described manual application work, the above-described conventional lubricating oil supply device is attached to the lifting body, and the lifting body is lifted and lowered for lubrication. It is conceivable that the oil of the oil supply device is automatically supplied to the guide rail and applied to the guide rail including portions other than the sliding surface. However, providing the lubricating oil supply device in this way increases equipment costs and installation costs, and has a problem in practicality.
本発明は、前述した従来技術における実情からなされたもので、その目的は、作業効率良く、また低コストでガイドレールに潤滑油を塗布することができるエレベータの給油装置及びエレベータの給油方法を提供することにある。 The present invention has been made based on the above-described situation in the prior art, and an object of the present invention is to provide an elevator oil supply apparatus and an elevator oil supply method capable of applying lubricating oil to a guide rail with good work efficiency and at low cost. There is to do.
前記目的を達成するために、本発明に係るエレベータの給油装置は、昇降路内を昇降する昇降体と、この昇降体を上下方向に案内するガイドレールと、前記昇降体に取り付けられ、前記ガイドレールの摺動面に摺接するガイドシューとを有するエレベータに備えられ、前記ガイドレールに潤滑油を供給するエレベータの給油装置において、それぞれ前記昇降体の前記ガイドレールに対向する側に設けられ、所定間隔で上下に配置された下側部材及び上側部材と、前記下側部材と前記上側部材との間に設置されて前記ガイドレールに接触し、前記潤滑油が含油された塗布パッドとを備え、前記下側部材及び前記上側部材の少なくとも一方は、前記ガイドシューを前記昇降体に取り付ける既設部材から成ることを特徴としている。 In order to achieve the above object, an elevator oil supply apparatus according to the present invention includes an elevating body that elevates and lowers in a hoistway, a guide rail that guides the elevating body in a vertical direction, and is attached to the elevating body. In an elevator oiling device that is provided in an elevator having a guide shoe that is in sliding contact with the sliding surface of the rail, and that supplies lubricating oil to the guide rail, each of the elevators is provided on a side facing the guide rail, and a lower member and an upper member disposed vertically at intervals, are installed between the upper member and the lower member in contact with the guide rail, e Bei the application pad wherein the lubricant is oil-containing At least one of the lower member and the upper member is an existing member that attaches the guide shoe to the lifting body .
また、前記目的を達成するために、本発明に係るエレベータの給油方法は、前述のエレベータの給油装置を用いて、昇降体を上下方向に案内するガイドレールに潤滑油を供給するエレベータの給油方法において、前記昇降体の前記ガイドレールに対向する側にそれぞれ設けられ、所定間隔で上下に配置された下側部材と上側部材との間に、前記潤滑油が含油され前記ガイドレールに接触する塗布パッドを設置し、前記塗布パッドを前記ガイドレールに接触させた状態で、前記昇降体を最上階と最下階との間で往復運転させて前記塗布パッドの潤滑油を前記ガイドレールに塗布し、塗布後に前記塗布パッドを前記下側部材と前記上側部材との間から取り外すようにしたことを特徴としている。 In order to achieve the above object, an elevator oil supply method according to the present invention is an elevator oil supply method that supplies lubricating oil to a guide rail that guides an elevating body in a vertical direction using the elevator oil supply device described above. In this case, the lubricant is impregnated between the lower member and the upper member, which are respectively provided on the side of the lifting body facing the guide rail and arranged vertically at a predetermined interval, and is applied so as to contact the guide rail With the pad installed and with the coating pad in contact with the guide rail, the lifting body is reciprocated between the uppermost floor and the lowermost floor to apply the lubricating oil of the coating pad to the guide rail. The coating pad is removed from between the lower member and the upper member after coating.
本発明に係るエレベータの給油装置及びエレベータの給油方法は、下側部材と上側部材との間に設置され、潤滑油が含油された塗布パッドによって作業効率良く、また低コストでガイドレールに潤滑油を塗布することができ、実用性に富む。 An elevator oil supply apparatus and an elevator oil supply method according to the present invention are provided between a lower member and an upper member, and work oil is applied to the guide rail at a low cost by a coating pad containing the lubricant. Can be applied and is highly practical.
以下、本発明に係るエレベータの給油装置及びエレベータの給油方法の実施の形態を図面に基づいて説明する。 Embodiments of an elevator oiling apparatus and an elevator oiling method according to the present invention will be described below with reference to the drawings.
図１に示すように、エレベータは、昇降路７に配置される昇降体すなわち乗りかご１及び釣り合い重り２と、これらの乗りかご１及び釣り合い重り２を上下方向に案内するガイドレール８と、乗りかご１と釣り合い重り２とを連結するロープ３と、例えば機械室２０に配置され、ロープ３が巻き掛けられる巻上機４及びそらせ車５とを備えている。巻上機４を回転駆動させることによりロープ３が移動し、乗りかご１及び釣り合い重り２がガイドレール８に沿って安定した状態で昇降するようになっている。 As shown in FIG. 1, the elevator includes a lifting body arranged in a hoistway 7, that is, a car 1 and a counterweight 2, a guide rail 8 that guides the car 1 and the counterweight 2 in the vertical direction, A rope 3 that connects the car 1 and the counterweight 2, and a hoisting machine 4 and a baffle 5 that are disposed in the machine room 20 and on which the rope 3 is wound are provided. The rope 3 is moved by rotationally driving the hoist 4, and the car 1 and the counterweight 2 are moved up and down along the guide rail 8 in a stable state.
前述したように従来にあっては、例えば潤滑油供給装置９が乗りかご１及び釣り合い重り２に設けられ、潤滑油供給装置９から常時供給される潤滑油がガイドレール８に塗布されるようになっている。また、乗りかご１及び釣り合い重り２にはそれぞれガイドレール８の摺動面に摺接するガイドシュー６が備えられている。なお、潤滑油供給装置９はガイドシュー６を鉛直上方から見たときに、その正射影が重なる状態で昇降体に備えられるのが一般的であった。 As described above, in the prior art, for example, the lubricating oil supply device 9 is provided in the car 1 and the counterweight 2 so that the lubricating oil that is constantly supplied from the lubricating oil supply device 9 is applied to the guide rail 8. It has become. Each of the car 1 and the counterweight 2 is provided with a guide shoe 6 that is in sliding contact with the sliding surface of the guide rail 8. Note that the lubricating oil supply device 9 is generally provided in the lifting body in a state where the orthogonal projections overlap when the guide shoe 6 is viewed from vertically above.
本実施形態に係る給油装置が備えられるエレベータは、例えばガイドシュー６としてオイルレスシューを備えている。そのため本実施形態では、常時潤滑油をガイドレール８に供給する潤滑油供給装置９は備えていない。本実施形態について述べる前に、本発明者らが先に考案した参考例について、図２〜図５に基づいて説明する。 The elevator provided with the oil supply apparatus according to the present embodiment includes an oilless shoe as the guide shoe 6, for example. Therefore, in this embodiment, the lubricating oil supply apparatus 9 which always supplies lubricating oil to the guide rail 8 is not provided. Before describing this embodiment, a reference example devised by the present inventors will be described with reference to FIGS.
図２に示すように、本発明者等が先に考案したエレベータの給油装置の参考例は、乗りかご１及び釣り合い重り２のそれぞれのガイドレール８に対向する側に設けられ、所定間隔で上下に配置された下側部材及び上側部材を備えている。また、この参考例は、下側部材と上側部材との間に配置されてガイドレール８に接触し、潤滑油が含油された塗布パッド１０を備えている。 As shown in FIG. 2, the reference example of the elevator oiling device previously devised by the present inventors is provided on the side facing the guide rails 8 of the car 1 and the counterweight 2, and is vertically moved at predetermined intervals. A lower member and an upper member disposed on the surface. Further, this reference example includes an application pad 10 that is disposed between the lower member and the upper member, contacts the guide rail 8, and contains lubricating oil.
塗布パッド１０は、ガイドレール８を挟み込む開口部１１を有する例えば不織布から成っている。下側部材は、ガイドレール８に向かって延設され、塗布パッド１０が載置される平板部を有する下架台１２から成っている。上側部材は、ガイドレール８に向かって延設され、下架台１２の平板部に対向する平板部を有する上架台１３から成っている。例えば下架台１２及び上架台１３は、乗りかご１及び釣り合い重り２の該当するものに対して着脱が可能に設けられている。これらの下架台１２と上架台１３との間に、開口部１１によってガイドレール８を挟み込むようにして塗布パッド１０を設置してある。 The application pad 10 is made of, for example, a nonwoven fabric having an opening 11 that sandwiches the guide rail 8. The lower member includes a lower base 12 that extends toward the guide rail 8 and has a flat plate portion on which the coating pad 10 is placed. The upper member includes an upper frame 13 that extends toward the guide rail 8 and has a flat plate portion that faces the flat plate portion of the lower frame 12. For example, the lower pedestal 12 and the upper pedestal 13 are provided so as to be attachable to and detachable from corresponding ones of the car 1 and the counterweight 2. A coating pad 10 is installed between the lower base 12 and the upper base 13 so that the guide rail 8 is sandwiched by the opening 11.
図３（ａ）図に示すように、第１例として塗布パッド１０は、開口部１１の幅寸法１１ａをガイドレール８の摺動面を含む部分の幅寸法８ａよりもわずかに小さくなるように設定し、開口部１１の奥行寸法１１ｂをガイドレール８の摺動面の奥行寸法８ｂよりもわずかに大きくなるように設定してある。本発明者らの試験結果から、塗布パッド１０の開口部１１の幅寸法１１ａをガイドレール８の幅寸法８ａの９５%〜９８％とすると、ガイドレール８に対する塗布パッド１０の密着性を確保でき、しかも均一で漏れの無い潤滑油の塗布を実現できることが確認されている。なお試験結果から、塗布パッド１０の開口部１１の幅寸法１１ａをガイドレール８の幅寸法８の９５％未満とすると、塗布パッド１０とガイドレール８との間の摩擦力が不要に大きくなってしまうことが確認されている。一方、開口部１１の幅寸法１１ａを、幅寸法８ａの９８％を超えるようにすると、塗布パッド１０とガイドレール８との間に十分な密着性を確保し難くなることが確認されている。 As shown in FIG. 3A, as a first example, the coating pad 10 has a width dimension 11a of the opening 11 slightly smaller than a width dimension 8a of the portion including the sliding surface of the guide rail 8. The depth dimension 11b of the opening 11 is set to be slightly larger than the depth dimension 8b of the sliding surface of the guide rail 8. From the test results of the present inventors, when the width 11a of the opening 11 of the application pad 10 is 95% to 98% of the width 8a of the guide rail 8, the adhesion of the application pad 10 to the guide rail 8 can be secured. Moreover, it has been confirmed that a uniform and leak-free lubricating oil can be applied. From the test results, if the width 11a of the opening 11 of the coating pad 10 is less than 95% of the width 8 of the guide rail 8, the frictional force between the coating pad 10 and the guide rail 8 becomes unnecessarily large. It has been confirmed that. On the other hand, it has been confirmed that if the width 11a of the opening 11 exceeds 98% of the width 8a, it is difficult to ensure sufficient adhesion between the coating pad 10 and the guide rail 8.
下架台１２と上架台１３を設けることについては、例えば図４（ａ）（ｂ）に示すように、下架台１２だけを設け、下架台１２に塗布パッド１０を載置した場合には、図４（ａ）に示すように、上昇時には下架台１２に支えられながら上昇し、ガイドレール８に潤滑油を良好に塗布できる。しかし図４（ｂ）図に示すように乗りかご１あるいは釣り合い重り２の下降時では、塗布パッド１０が潤滑油を介して下架台１２の一部に張り付いたりすると共に、塗布パッド１０の開口部１１ａとガイドレール８の摺動面との摩擦力のために、下架台１２の下降に引きずられるかたちで開口部１１の先端側は上方に残り、開口部１１の末端側は下方に下がった状態となるような位置ずれを生じる。この位置ずれが大きくなると塗布パッド１０が脱落する虞がある。図４（ｃ）図に示すように、下架台１２に対向させて上架台１３を設けた本実施形態では、前述の位置ずれを少なく抑え、位置ずれによる塗布パッド１０の脱落を防ぐことができる。 For example, as shown in FIGS. 4A and 4B, when the lower base 12 and the upper base 13 are provided, only the lower base 12 is provided, and the coating pad 10 is placed on the lower base 12, as shown in FIG. As shown to 4 (a), it raises, being supported by the undercarriage 12 at the time of a raise, and can apply | coat lubricating oil to the guide rail 8 satisfactorily. However, as shown in FIG. 4B, when the car 1 or the counterweight 2 is lowered, the application pad 10 sticks to a part of the gantry 12 via the lubricating oil, and the application pad 10 has an opening. Due to the frictional force between the portion 11a and the sliding surface of the guide rail 8, the tip end side of the opening portion 11 remains upward and the end side of the opening portion 11 descends downwardly by being dragged by the lowering of the lower base 12. A position shift that causes a state occurs. If this positional deviation becomes large, the coating pad 10 may fall off. As shown in FIG. 4C, in the present embodiment in which the upper mount 13 is provided so as to face the lower mount 12, the above-described positional shift can be suppressed and the application pad 10 can be prevented from falling off due to the positional shift. .
なお、塗布パッド１０の形状を、図３（ｂ）図に示す第２例のように設定してもよい。この図３（ｂ）図に示す塗布パッド１０は、開口部１１の幅寸法を、ガイドレール８の摺動面に接触する部分の開口部寸法に比べて、ガイドレール８側に位置する先端部の開口部寸法が小さくなるように設定したものである。このように設定した塗布パッド１０では、位置ずれをさらに抑え、脱落を確実に防ぐことができる。 Note that the shape of the coating pad 10 may be set as in the second example shown in FIG. The coating pad 10 shown in FIG. 3B has a tip end portion located on the guide rail 8 side in comparison with the opening size of the portion of the opening 11 in contact with the sliding surface of the guide rail 8. The size of the opening is set to be small. With the coating pad 10 set in this way, it is possible to further suppress the positional deviation and prevent the dropping off reliably.
なお、前述した塗布パッド１０の奥行寸法１１ｂを、ガイドレール８の摺動面の奥行寸法８ｂよりも５ｍｍ長くした状態から小さくしていくと、次第に大きな傾きの位置ずれに対応できなくなってしまうことを本発明者らは確認している。この場合に、位置ずれに対応するためには、下架台１２と上架台１３との間隔を狭くしなければならないが、そのように狭くすると塗布パッド１０を下架台１２と上架台１３との間に設置し難くなる。逆に、奥行寸法１１ｂが奥行寸法８ｂよりも１０ｍｍを超える程になると大きな傾きの位置ずれに対応できるようになっていくものの、塗布パッド１０の形状維持が難しくなったり、奥行寸法１１ｂと奥行寸法８ｂとの差である余裕代が過度に大きくなって不要に他の機器に接触して問題を起こすことも考えられる。さらに奥行寸法１１ｂを奥行寸法８ｂよりも１５ｍｍを超える程長くすると、余裕代を長めにすることの意義が略失われてしまう。したがって、塗布パッド１０の開口部１１の奥行寸法１１ｂを、ガイドレール８の摺動面の奥行寸法８ｂよりも１〜１５ｍｍ程長く、好ましくは５〜１０ｍｍ程度長く設定するとよい。このように塗布パッド１０の開口部１１の奥行寸法１１ｂを設定することにより、塗布パッド１０がガイドレール８の摺動面に対して脱落する方向に位置ずれしても、塗布パッド１０を極力脱落させずにガイドレール８の摺動面に接触した状態を維持できる。 In addition, if the depth dimension 11b of the coating pad 10 described above is reduced from a state in which it is 5 mm longer than the depth dimension 8b of the sliding surface of the guide rail 8, it becomes impossible to cope with a positional deviation with a large inclination gradually. The present inventors have confirmed. In this case, in order to cope with the positional deviation, the interval between the lower pedestal 12 and the upper pedestal 13 must be narrowed, but if it is so narrow, the coating pad 10 is placed between the lower pedestal 12 and the upper pedestal 13. It becomes difficult to install in. On the contrary, when the depth dimension 11b exceeds 10 mm from the depth dimension 8b, it becomes possible to cope with a large inclination displacement, but it becomes difficult to maintain the shape of the coating pad 10, or the depth dimension 11b and the depth dimension. It is also conceivable that the margin, which is the difference from 8b, becomes excessively large, causing problems by contacting other devices unnecessarily. Furthermore, if the depth dimension 11b is made longer than the depth dimension 8b by more than 15 mm, the significance of increasing the margin is substantially lost. Accordingly, the depth dimension 11b of the opening 11 of the coating pad 10 is set to be longer by about 1 to 15 mm, preferably about 5 to 10 mm, than the depth dimension 8b of the sliding surface of the guide rail 8. By setting the depth dimension 11b of the opening 11 of the coating pad 10 in this manner, the coating pad 10 is removed as much as possible even if the coating pad 10 is displaced in the direction of dropping with respect to the sliding surface of the guide rail 8. The state which contacted the sliding surface of the guide rail 8 can be maintained without doing.
なお、塗布パッド１０を図３（ｂ）図に示すように設定する場合は、前述した開口部１１の奥行寸法１１ｂとガイドレール８の摺動面の奥行寸法８ｂとの関係を考慮した上で、開口部１１の先端部を狭める形状に設定するとよい。 When the coating pad 10 is set as shown in FIG. 3B, the relationship between the depth 11b of the opening 11 and the depth 8b of the sliding surface of the guide rail 8 is taken into consideration. The shape of the opening 11 may be narrowed.
また、下架台１２と上架台１３との間隔は、小さいほど塗布パッド１０の位置ずれを抑制できるものである。しかし、小さすぎると塗布パッド１０を下架台１２と上架台１３との間に設置し難くなり、また、取り外し難くなる。一方、下架台１２と上架台１３との間隔が大きすぎると、塗布パッド１０の位置ずれを抑制する効果が得られなくなり、さらには大きく傾いた塗布パッド１０が下架台１２上で立ち上がった状態に近づき、ガイドレール８との摩擦と上架台１３による押し下げでぐしゃぐしゃに変形したりすることも考えられる。これについて本発明者らは、試験結果によって例えば図５（ａ）図の第１例に示すように、下架台１２の平板部と上架台１３の平板部との間隔Ｌを、塗布パッド１０の全体奥行寸法ｌの１／２以下に設定することが有効であることを確認している。さらに本発明者らは、下架台１２と上架台１３との間隔Ｌを塗布パッド１０の全体奥行寸法ｌの１／３〜１／２とすると、塗布パッド１０の脱落を確実に防止しつつ、塗布パッド１０の設置及び取り外しの良好な作業性を確保できることを確認している。 Moreover, the position gap of the coating pad 10 can be suppressed, so that the space | interval of the lower mount 12 and the upper mount 13 is small. However, if it is too small, it will be difficult to install the coating pad 10 between the lower mount 12 and the upper mount 13, and it will be difficult to remove. On the other hand, if the distance between the lower pedestal 12 and the upper pedestal 13 is too large, the effect of suppressing the displacement of the application pad 10 cannot be obtained, and the greatly inclined application pad 10 stands on the lower pedestal 12. It is conceivable that the outer wall 13 approaches and is crumpled by friction with the guide rail 8 and being pushed down by the upper base 13. In this regard, the present inventors set the distance L between the flat plate portion of the lower pedestal 12 and the flat plate portion of the upper pedestal 13 according to the test results, as shown in the first example of FIG. It has been confirmed that setting it to ½ or less of the overall depth dimension l is effective. Furthermore, the present inventors reliably prevent the coating pad 10 from falling off when the distance L between the lower platform 12 and the upper platform 13 is 1/3 to 1/2 of the entire depth l of the coating pad 10. It has been confirmed that good workability of installation and removal of the coating pad 10 can be secured.
なお、図５（ａ）図に示す第１の例では、下架台１２の平板部と上架台１３の平板部とが平行となるように構成してある。これとは異なって、同図５（ｂ）図の第２例で示すように、下架台１２を下方に向かうように例えば５〜１０°傾け、また上架台１３を上方に向けて５〜１０°傾けるように構成してもよい。このように構成したものでは、乗りかご１及び釣り合い重り２が下方に向かって動く時には上架台１３の傾きとガイドレール８との摺動面での摩擦により、同様に、上方に向かって動く時は下架台１２の傾きとガイドレール８との摺動面での摩擦によって、塗布パッド１０がよりガイドレール８に密着しようとする方向に力が働くので、塗布パッド１０の位置ずれを矯正でき、より好ましい。このように構成する場合には、下架台１２の平板部の先端と上架台１３の平板部の先端との間隔Ｌが、塗布パッド１０の全体奥行寸法ｌの１／２以下に、好ましくは１／３〜１／２の範囲内になるようにすると都合が良い。 In addition, in the 1st example shown to Fig.5 (a) figure, it comprises so that the flat plate part of the lower mount 12 and the flat plate part of the upper mount 13 may become parallel. In contrast to this, as shown in the second example of FIG. 5 (b), the lower pedestal 12 is tilted, for example, by 5 to 10 degrees downward, and the upper pedestal 13 is directed upward to 5-10. It may be configured to tilt. With the above structure, when the car 1 and the counterweight 2 move downward, similarly, when the car 1 and the counterweight 2 move upward due to the inclination of the upper base 13 and the friction on the sliding surface with the guide rail 8. Since the force acts in the direction in which the application pad 10 is more closely attached to the guide rail 8 due to the inclination of the undercarriage 12 and the friction on the sliding surface with the guide rail 8, the positional deviation of the application pad 10 can be corrected. More preferred. In the case of such a configuration, the distance L between the tip of the flat plate portion of the lower pedestal 12 and the tip of the flat plate portion of the upper pedestal 13 is ½ or less of the overall depth dimension l of the coating pad 10, preferably 1 It is convenient to make it within the range of / 3 to 1/2.
