Description

この発明はエスカレータや動く歩道などの乗客コンベアの欄干に設けられて踏段と同期して回転駆動される乗客コンベア用移動手摺を補修するための加熱加圧装置及びその接続方法に関するものである。   The present invention relates to a heating and pressurizing apparatus for repairing a moving handrail for a passenger conveyor that is provided on a railing of a passenger conveyor such as an escalator or a moving sidewalk and is driven to rotate in synchronization with a step and a connection method thereof.

一般にエスカレータなどの乗客コンベアは、図４に示す如く、上下階側乗降口相互間において、無端状に配した踏段１と、その左右両サイドの欄干２の外周に配した無端状の移動手摺３とを、相互に同期させて同方向に回転移動させることで乗客を運搬するものである。そうしたエスカレータの移動手摺３は、一般に欄干２の下部内の移動手摺帰路途中に設けた複数の駆動ローラ４とその各駆動ローラ４の下側に転接すべく配設した加圧ローラ５との間に通されて、その両ローラ４、５間に図５（図４のＣ−Ｃ線に沿う断面図）に示す如く挟圧されて、その駆動ローラ４の回転による摩擦力で駆動されるようになっていると共に、その駆動される移動手摺３は欄干２の下部内帰路側では複数の案内ローラ（図示せず）により案内され、さらに欄干２の上部では欄干フレームに取付けた手摺ガイドレール１０により案内されて、エンドレス状に回転移動するようになっている。   In general, a passenger conveyor such as an escalator has an endless moving handrail 3 arranged on the outer periphery of a step 1 arranged endlessly between the upper and lower floor side entrances and a balustrade 2 on both right and left sides as shown in FIG. Are transported by rotating them in the same direction in synchronization with each other. Such a moving handrail 3 of the escalator is generally composed of a plurality of driving rollers 4 provided in the middle of the return path of the moving handrail in the lower part of the balustrade 2 and a pressure roller 5 disposed so as to be in rolling contact with the lower side of each driving roller 4. As shown in FIG. 5 (cross-sectional view taken along the line CC in FIG. 4), the two rollers 4 and 5 are sandwiched between the rollers 4 and 5 and are driven by the frictional force generated by the rotation of the drive roller 4. The handrail 3 to be driven is guided by a plurality of guide rollers (not shown) on the return path in the lower part of the balustrade 2, and the handrail guide rail attached to the balustrade frame on the upper part of the balustrade 2 10 is guided to rotate and move endlessly.

図６は移動手摺３と手摺ガイドレール１０を含む摺動機構の一部断面図であって、図４の移動手摺往路側の断面図である。
移動手摺３自体は図６に示す如く、全体としてＣ字型の横断面を有し、全体としてＴ字型の内側スロットを構成し、Ｔ字型スロットの周りに延びる芯体層３１と、この芯体層３１の外部の周りに延び、移動手摺３の外側輪郭を定める表面層３２と、芯体層３１の内側面に結合されたスライダー層３３と、芯体層３１内に延びる伸び防止手段（抗張体）３４とを備えている。芯体層３１、表面層３２は熱可塑性エラストマーが使用されている。 6 is a partial cross-sectional view of the sliding mechanism including the moving handrail 3 and the handrail guide rail 10, and is a cross-sectional view of the moving handrail forward path side in FIG.
As shown in FIG. 6, the movable handrail 3 itself has a C-shaped cross section as a whole, constitutes a T-shaped inner slot as a whole, and a core layer 31 extending around the T-shaped slot, A surface layer 32 that extends around the outside of the core body layer 31 to define the outer contour of the moving handrail 3, a slider layer 33 that is coupled to the inner surface of the core body layer 31, and an extension preventing means that extends into the core body layer 31. (Tensile body) 34. A thermoplastic elastomer is used for the core layer 31 and the surface layer 32.

乗客コンベアの欄干２上部の手摺ガイドレール１０は図６に示す如く、その両側凸状部に合成樹脂製ガイドクリップ１０ａが装着され、移動手摺３の内周面に摺接するようになっている。   As shown in FIG. 6, the handrail guide rail 10 at the upper part of the balustrade 2 of the passenger conveyor is provided with synthetic resin guide clips 10 a on the convex portions on both sides thereof so as to be in sliding contact with the inner peripheral surface of the movable handrail 3.

移動手摺３の最内側のスライダー層３３には帆布が用いられているが、このスライダー層３３の役目は手摺ガイドクリップ１０ａと摺動する時の摩擦係数を適切な値にするためと、移動手摺３の形状を所定の強度を持ってＣ字型に維持するためである。   The canvas is used for the innermost slider layer 33 of the moving handrail 3. The role of the slider layer 33 is to set the coefficient of friction when sliding with the handrail guide clip 10a to an appropriate value. This is because the shape 3 is maintained in a C shape with a predetermined strength.

この移動手摺の製造方法は、芯体層用の熱可塑性エラストマーと金属製又は合成繊維製の抗張体及びスライダーを成形機から同時に押出して該抗張体及びスライダーを抱合した断面略Ｃ字状の芯体層を成形する工程と、透明を含み客先指定色等の所望の色に着色された表面層用の熱可塑性エラストマーを成形機から押出して断面略Ｃ字状の表面層を成形する工程を少なくとも具備している。   This moving handrail manufacturing method has a substantially C-shaped cross section in which a thermoplastic elastomer for a core body layer, a metal or synthetic fiber tensile body and a slider are simultaneously extruded from a molding machine, and the tensile body and the slider are conjugated. And forming a surface layer having a substantially C-shaped cross section by extruding from a molding machine a thermoplastic elastomer for a surface layer that is transparent and is colored in a desired color such as a customer-specified color. At least a process.

乗客コンベアの移動手摺３は、エンドレス（環状）にして乗客コンベアに組込まれるので、直線状の移動手摺３を所定長さに切断しその両端部を接続してエンドレスに形成する。まず、所定の長さに切断された移動手摺３の両端部から、芯体層３１、スライダー層３３及び表面層３２の端部を除去し、抗張体３４を露出させる。次に、露出された抗張体３４の両端部を、接着剤を介して互いに重ね合わせる。この後、接続部を図７に示す金型１００内にセットする。金型１００は、上型２００と、下型３００と、三分割されて下型３００の凹部３００ａ内に嵌合する中型４００とからなる。さらに前記金型１００内のキャビティに芯材用熱可塑性エラストマーを充填し、加熱後冷却硬化させる。これにより接続部の成形が完了する（例えば、特許文献１参照）。   Since the moving handrail 3 of the passenger conveyor is incorporated into the passenger conveyor in an endless (annular) form, the linear moving handrail 3 is cut into a predetermined length, and both ends thereof are connected to form an endless shape. First, the ends of the core body layer 31, the slider layer 33, and the surface layer 32 are removed from both ends of the moving handrail 3 cut to a predetermined length, and the tensile body 34 is exposed. Next, both ends of the exposed tensile body 34 are overlapped with each other via an adhesive. Thereafter, the connecting portion is set in the mold 100 shown in FIG. The mold 100 includes an upper mold 200, a lower mold 300, and a middle mold 400 that is divided into three and fits into the recess 300 a of the lower mold 300. Further, the cavity in the mold 100 is filled with the thermoplastic elastomer for the core material, and is heated and cooled and cured. This completes the formation of the connecting portion (see, for example, Patent Document 1).

移動手摺の接続部の詳細は図８、図９（図８のＤ−Ｄ線に沿う断面図）に示すように、接続される移動手摺本体部３同士の中間に充填部３ａが存在する。この充填部３ａにはスライダー部分が無いので、図８、図９のア〜エ部は手摺の屈曲により亀裂が生じ、長期間使用すると、この部分から移動手摺が破断する。したがって、移動手摺の破断を防止するため、図１０、図１１（図１０のＥ−Ｅ線に沿う断面図）に示すように、充填部３ａに補強のための当て布３３ａを設けている。当て布３３ａは、上記環状接続時にスライダー３３との間に熱硬化性接着剤を塗布して金型１００内にセットされる。   As shown in detail in FIG. 8 and FIG. 9 (cross-sectional view taken along the line DD in FIG. 8), the filling portion 3a exists in the middle of the connected handrail main body portions 3 as shown in detail in FIG. Since the filling portion 3a does not have a slider portion, the portions a to d in FIGS. 8 and 9 are cracked by bending of the handrail, and when used for a long time, the moving handrail is broken from this portion. Therefore, in order to prevent the moving handrail from being broken, as shown in FIGS. 10 and 11 (cross-sectional views taken along the line EE in FIG. 10), a filling cloth 33a for reinforcement is provided in the filling portion 3a. The application cloth 33a is set in the mold 100 by applying a thermosetting adhesive to the slider 33 during the annular connection.

図７において、金型１００内の発熱体としての電熱ユニットは、上型２００に電熱ユニットＲ１、Ｒ２が設けられ、下型３００に電熱ユニットＲ３、Ｒ４が設けられている。金型１００は、更に上型２００及び下型３００を締結するための複数個の締め付けボルト６０と、上型２００内に設けられた冷却用流体が通る冷却穴７０、７０ａ、下型３００内に設けられた冷却用流体が通る冷却穴８０、８０ａを備えている。なお、図中、３は移動手摺である。
上記構成により、乗客コンベアの移動手摺３を接続する場合は、図７に示すように、移動手摺３を、上型２００、中型４００及び下型３００で挟み込み、締め付けボルト６０で上型２００と下型３００に加圧力を付与するようにすればよい。
上型２００と下型３００に加圧力を付与した状態で、電熱ユニットＲ１〜Ｒ４を発熱させれば、移動手摺３を熱融着によって接続することができる。
次に、接続が完了して、金型１００を冷却する方法について述べる。
まず電熱ユニットＲ１〜Ｒ４の発熱を停止させ、次に、上型２００内に設けられた冷却用流体が通る冷却穴７０、７０ａと、下型３００内に設けられた冷却用流体が通る冷却穴８０、８０ａに、冷却用流体を注入して金型１００を冷却するものである。 In FIG. 7, in the electric heating unit as a heating element in the mold 100, electric heating units R <b> 1 and R <b> 2 are provided on the upper mold 200, and electric heating units R <b> 3 and R <b> 4 are provided on the lower mold 300. The mold 100 further includes a plurality of fastening bolts 60 for fastening the upper mold 200 and the lower mold 300, cooling holes 70 and 70 a through which a cooling fluid provided in the upper mold 200 passes, and the lower mold 300. Cooling holes 80 and 80a through which the provided cooling fluid passes are provided. In the figure, reference numeral 3 denotes a moving handrail.
With the above configuration, when the moving handrail 3 of the passenger conveyor is connected, the moving handrail 3 is sandwiched between the upper mold 200, the middle mold 400 and the lower mold 300 as shown in FIG. A pressing force may be applied to the mold 300.
If the electrothermal units R1 to R4 generate heat in a state where pressure is applied to the upper mold 200 and the lower mold 300, the movable handrail 3 can be connected by thermal fusion.
Next, a method for cooling the mold 100 after the connection is completed will be described.
First, the heat generation of the electric heating units R1 to R4 is stopped, and then the cooling holes 70 and 70a through which the cooling fluid provided in the upper mold 200 passes and the cooling holes through which the cooling fluid provided in the lower mold 300 pass. The cooling fluid is injected into 80 and 80a to cool the mold 100.

しかし、従来の移動手摺の接続装置では、接続時に熱可塑性エラストマーである熱可塑性ウレタンが金型１００内で加熱され金型内の圧力が上昇すると、金型の両端は開放されているため、熱可塑性ウレタンが金型の両側に延びて行き、熱硬化性接着剤で接着した当て布３３ａと、スライダー３３の間に引っ張り力が発生し、相対運動が発生するため、接着した当て布３３ａとスライダー３３間の硬化しかかっている接着剤の接着力が低下し、所定の接着力が得られないという不具合が発生することがある。また、移動手摺をエスカレータ実機で実用運転した際に掛かる移動手摺の引っ張り力によって接着力が所定値以下となってこの接続部の当て布３３ａが剥がれるという問題点があった。   However, in a conventional moving handrail connecting device, when thermoplastic urethane, which is a thermoplastic elastomer, is heated in the mold 100 during connection and the pressure in the mold rises, both ends of the mold are opened. Since the plastic urethane extends to both sides of the mold, a tensile force is generated between the application cloth 33a bonded with the thermosetting adhesive and the slider 33, and a relative motion is generated. Therefore, the bonded application cloth 33a and the slider The adhesive force of the adhesive that is about to cure between the three adhesive members 33 is reduced, and a problem that a predetermined adhesive force cannot be obtained may occur. Further, there is a problem in that the adhesive force becomes less than a predetermined value due to the pulling force of the moving handrail when the moving handrail is put into practical use with the actual escalator, and the application cloth 33a of the connecting portion is peeled off.

この発明は、上述のような課題を解決するためになされたもので、移動手摺の接続部の当て布の接着力が所定値以下となった場合、移動手摺を補修するための乗客コンベア用移動手摺の加熱加圧装置及びその接続方法を提供するものである。なお、接着力の大きさは治具を用いて数値評価される。   This invention was made in order to solve the above-described problems. When the adhesive force of the application cloth of the connecting portion of the moving handrail becomes a predetermined value or less, the movement for the passenger conveyor for repairing the moving handrail. The present invention provides a handrail heating and pressing apparatus and a method for connecting the apparatus. The magnitude of the adhesive force is numerically evaluated using a jig.

この発明に係る乗客コンベア用移動手摺の加熱加圧装置においては、最内側にスライダー層を備えた乗客コンベア用熱可塑性エラストマー移動手摺の接続部に接着された当て布の接着力が所定値以下となった際に用いられるものにおいて、移動手摺化粧層表面の温度を化粧層表面が溶融する温度未満に維持しつつ、当て布の近傍を加熱加圧する金型を備えたものである。   In the heating and pressurizing device for the moving handrail for passenger conveyor according to the present invention, the adhesive force of the application cloth bonded to the connecting portion of the thermoplastic elastomer moving handrail for passenger conveyor having the slider layer on the innermost side is equal to or less than a predetermined value. In such a case, a mold for heating and pressurizing the vicinity of the patch is provided while maintaining the temperature of the surface of the moving handrail decorative layer below the temperature at which the surface of the decorative layer melts.

また、当て布を加熱加圧する金型は、上型、下型及び移動手摺の内側に挿入される中型とで構成され、この金型の中型のみを加熱可能にする手段を備えたものである。   The mold for heating and pressurizing the application cloth is composed of an upper mold, a lower mold, and a middle mold that is inserted inside the moving handrail, and includes means for heating only the middle mold of the mold. .

また、金型と移動手摺化粧層との間にクッション材を挿入したものである。   Further, a cushion material is inserted between the mold and the moving handrail decorative layer.

この発明に係る乗客コンベア用移動手摺の接続方法においては、最内側にスライダー層を備えた乗客コンベア用熱可塑性エラストマー移動手摺の接続部に接着された当て布の接着力が低下した際に用いられるものであって、接続部の当て布の接着力が所定値以下となった時、当て布をスライダーから鋭利な刃物等で引き剥がすステップと、引き剥がした当て布とスライダーとの間に再度熱硬化性の接着材を塗布してから金型に入れるステップと、金型内で移動手摺の化粧層表面の温度を、化粧層表面が溶融する温度未満に維持しつつ、当て布の近傍を加熱加圧するステップとを備えたものである。   In the connection method of the moving handrail for passenger conveyors according to the present invention, it is used when the adhesive force of the patch bonded to the connecting portion of the thermoplastic elastomer moving handrail for passenger conveyor having the slider layer on the innermost side is reduced. When the adhesive strength of the contact cloth of the connecting portion becomes less than a predetermined value, heat is again applied between the step of peeling the patch cloth from the slider with a sharp blade, and between the peeled patch cloth and the slider. Applying a curable adhesive before placing it in the mold, and heating the vicinity of the application cloth while maintaining the temperature of the decorative layer surface of the moving handrail below the temperature at which the decorative layer surface melts in the mold And a pressurizing step.

また、接続部の当て布の接着力が所定値以下となった時、当て布をスライダーから鋭利な刃物等で引き剥がすステップと、引き剥がした当て布とスライダーとの間に再度熱硬化性の接着材を塗布してから金型に入れるステップと、金型と接着剤が塗布された移動手摺表面との間にクッション材を入れるステップと、金型内で移動手摺の化粧層表面の温度を、化粧層表面が溶融する温度未満に維持しつつ、当て布の近傍を加熱加圧するステップとを備えたものである。   In addition, when the adhesive strength of the patch of the connecting portion becomes a predetermined value or less, the step of peeling the patch from the slider with a sharp blade or the like, and the thermosetting again between the stripped patch and the slider. Applying the adhesive and then placing it in the mold, placing the cushion material between the mold and the surface of the moving handrail to which the adhesive has been applied, and the temperature of the decorative layer surface of the moving handrail in the mold And heating and pressurizing the vicinity of the application cloth while maintaining the temperature below the melting temperature of the decorative layer surface.

この発明によれば、移動手摺の接続部の接着力が所定値以下となって、移動手摺の当て布が剥離しても、現地にても容易に補修することができるという効果がある。   According to this invention, the adhesive force of the connection part of a moving handrail becomes below a predetermined value, and even if the applicator of a moving handrail peels, there exists an effect that it can repair easily also in the field.

実施の形態１．
以下、この発明の実施の形態１における乗客コンベア用移動手摺の接続部補修装置を図１により説明する。
図１はこの発明の実施の形態１における乗客コンベア用移動手摺の接続部補修装置を示す金型の構造図、図２は乗客コンベア用移動手摺の接続部補修装置により補修される接続部を示す内面側から見た図、図３は図２のＡ−Ａ線に沿った断面図である。
図１において、接続部補修装置の金型１０１は、上型２０１と、下型３０１と、三分割されて下型３０１の凹部３０１ａ内に嵌合する中型４０１とからなる。金型１０１内の上型２０１、下型３０１には発熱体としての電熱ユニット及び冷却用流体が通る冷却穴は設けられていない。しかし、三分割された中型４０１のうちの中央に位置する型に電熱ユニットＲ５及び冷却用流体が通る冷却穴９０が設けられている。また金型１０１は、上型２０１及び下型３０１を締結するための複数個の締め付けボルト６０を備えている。なお、図中、３は移動手摺である。移動手摺３の接続部の当て布３３ａの接着力が所定値以下となったと認められる時には、当て布３３ａをスライダー層３３から鋭利な刃物等で引き剥がす。この時、図２、図３に示すように、当て布３３ａの両側耳部３３ｂ、３３ｃは、熱可塑性ウレタンが当て布３３ａに強力に含浸しているため、強度低下も無いし、刃物で引き剥がすことも出来ない。一方、図２、図３に示すように、当て布３３ａの両側耳部３３ｂ、３３ｃ間に存在するスライダー３３面との接着部３３ｄは、鋭利な刃物等で容易に引き剥がすことができるものである。そして、引き剥がした当て布３３ａとスライダー３３との間に再度熱硬化性接着剤を塗布して、上記接続部補修装置の金型１０１に入れる。 Embodiment 1 FIG.
Hereinafter, the connection part repair apparatus of the moving handrail for passenger conveyors in Embodiment 1 of this invention is demonstrated with reference to FIG.
FIG. 1 is a structural diagram of a mold showing a connecting part repairing device for a moving handrail for a passenger conveyor in Embodiment 1 of the present invention, and FIG. 2 shows a connecting part repaired by the connecting part repairing device for a moving handrail for a passenger conveyor. FIG. 3 is a cross-sectional view taken along line AA in FIG. 2 as viewed from the inner surface side.
In FIG. 1, the mold 101 of the connecting portion repairing apparatus includes an upper mold 201, a lower mold 301, and a middle mold 401 that is divided into three and fits into a recess 301 a of the lower mold 301. The upper mold 201 and the lower mold 301 in the mold 101 are not provided with an electric heating unit as a heating element and a cooling hole through which a cooling fluid passes. However, a cooling hole 90 through which the electric heating unit R5 and the cooling fluid pass is provided in a mold located at the center of the three-divided middle mold 401. The mold 101 includes a plurality of fastening bolts 60 for fastening the upper mold 201 and the lower mold 301. In the figure, reference numeral 3 denotes a moving handrail. When it is recognized that the adhesive force of the contact cloth 33a at the connection portion of the moving handrail 3 has become a predetermined value or less, the contact cloth 33a is peeled off from the slider layer 33 with a sharp blade or the like. At this time, as shown in FIG. 2 and FIG. 3, the both-side ears 33b and 33c of the application cloth 33a are strongly impregnated with thermoplastic urethane in the application cloth 33a. It cannot be peeled off. On the other hand, as shown in FIG. 2 and FIG. 3, the adhesive portion 33d with the slider 33 surface existing between the both side ears 33b and 33c of the batter 33a can be easily peeled off with a sharp blade or the like. is there. Then, a thermosetting adhesive is applied again between the peeled application cloth 33a and the slider 33, and is put into the mold 101 of the connection portion repair apparatus.

移動手摺３を金型１０１で加圧すると、上型２０１、下型３０１の両端部あるいは型の面に存在する僅かな凸凹が移動手摺３の表面に圧痕を生じることがある。そこで、このような圧痕を防止するために、図１に示すように、ゴム、プラスティックシート等のクッション材４０を金型１０１と移動手摺３間に入れて、移動手摺３を締め付けボルト６０で加圧する。   When the movable handrail 3 is pressed with the mold 101, a slight unevenness present on both ends of the upper mold 201 and the lower mold 301 or on the surface of the mold may cause an impression on the surface of the movable handrail 3. Therefore, in order to prevent such indentation, as shown in FIG. 1, a cushion material 40 such as rubber or a plastic sheet is inserted between the mold 101 and the moving handrail 3, and the moving handrail 3 is added with the tightening bolt 60. Press.

次に、三分割された中型４０１のうちの中央に位置する型に設けた電熱ユニットＲ５に通電し、中型４０１だけを加熱すると、当て布３３ａに塗布された熱硬化性接着剤が硬化する。この時、熱可塑性ウレタンは加熱されないか、もしくは加熱されても化粧層表面が溶融する温度未満に維持されるので、当て布３３ａとスライダー３３間には相対運動は発生しない。当て布３３ａの接着力が所定値以上に確保されたら、中型４０１のうちの中央に位置する型に設けた冷却穴９０に冷却用流体を通流して、金型１０１及び移動手摺３を冷却することで、補修が完了する。   Next, when the electric heating unit R5 provided in the mold located in the center of the three divided middle molds 401 is energized and only the middle mold 401 is heated, the thermosetting adhesive applied to the application cloth 33a is cured. At this time, the thermoplastic urethane is not heated, or even if it is heated, it is kept below the temperature at which the decorative layer surface melts, so that no relative movement occurs between the application cloth 33a and the slider 33. When the adhesive force of the application cloth 33a is secured to a predetermined value or more, the cooling fluid is passed through the cooling hole 90 provided in the mold located in the center of the middle mold 401 to cool the mold 101 and the moving handrail 3. This completes the repair.
