Description
The present invention relates to movable passageway handrail, especially about can prevent because of with guide the movable passageway handrail that rail friction electrifies into.
As shown in Figure 4, past, the handrail (hand guiding) that uses in the movable passageway as escalator and travelator etc. is made of core body 2 and the ornamental rubber layer 3 that is arranged on its outside face, described core body 2 is established the reinforcement 1 of metal filament flexible cord one class in being, with cohesiveness rubber etc. many sheet of canvas is changed into the part that section is roughly the C font.
Yet, the handrail of such formation in use, with the fixing guide rail periphery tabling of guiding into, along this guide rail tape transport Cyclic Rings around, recently as guide into guide rail its with metalworks such as the contact surface replacement iron of handrail, corrosion-resistant steel, aluminium be synthetic resin such as polyethylene, polyester, polyamide, polyacetal.
And, so far as the handrail canvas, though used cotton canvas, but in recent years with improve handrail intensity, when improving outdoor application fastness to water, reduce and guide into guide rail the friction impedance, to improve antifriction consumption etc. be purpose, will place the most inboard only with guide the surperficial canvas that guide rail joins into, or the full canvas that comprises this surface canvas makes syntheticfibres doublings such as using polyvinyl alcohol, polyester, polyolefin, polyamide, isoallyl silk or rubs that canvas that stubborn silk (vinylon, polyester, polyethylene, polypropylene, nylon, isoallyl silk) is made into is more to be seen with the hands.
But, in the handrail that uses such canvas, when operation according to described synthetic resin making to guide rail triboelectrification mutually, often make whole handrail charged, Here it is problem place.
Promptly, cotton fiber resistance is lower, since because of fricative electric charge at inner dissipation in short-term, so in the handrail that uses cotton canvas, almost do not have whole charged danger, yet the electrical insulating property of syntheticfibres is extremely strong, so syntheticfibres canvas and guide that fricative electric charge may dissipate hardly between guide rail into, make handrail integral body especially decorate the rubber layer surface charging, its voltage often reaches thousands of volts.
In case passenger's hand touches on charged handrail surface like this, because of moment is flow through electric current in vivo and produces electric picotement and feel, even out of reach human electric shock sense also can diminish attractive in appearance decorating rubber layer surface attachment dust etc.
For addressing the above problem, make canvas repeatedly become single-piece cohesiveness rubber layer with the conducting rubber formation in the past, prevent handrail charged (spy opens clear 63-173174 communique record) with this.
Yet in this handrail,,, be designed to the conducting rubber layer not between the most inboard surperficial twine hole, oozing out for preventing that slickness (sliding) takes place thus to descend if strengthen with the friction of guiding guide rail into, thereby, conductive layer do not exposed.Therefore, be difficult to ground connection, also just can not prevent charged fully.
The present invention is for addressing these problems, provide a kind of movable passageway with pick out hand, have prevent because of with guide rail friction into and cause charged good result, and the walking slickness is good.
Movable passageway handrail of the present invention, dress intensity retaining member in vertically, become substantially in the cross section on the core body of the laminated polylith canvas in C font ground, the decoration rubber layer is set, it is characterized in that in described canvas, being positioned at least the most inboard canvas and have as the electric conductivity line of knitting line.
The movable passageway handrail of the present invention's the 2nd scheme, in vertically, the intensity retaining member is housed, change on the core body of polylith canvas in the cross section with becoming the C font substantially, the decoration rubber layer is set, it is characterized in that in described canvas, being positioned at least and inweave electric conductivity shoestring on the most inboard canvas.
In the present invention, as the intensity retaining member, use has as twisting the metal flexible cord closes steel wire and twist the strand that closes polyamide fibre, the contour stretching resistance syntheticfibres of aromatic polyamide fibre, or the high tensile power of steel band, stainless steel band, synthetic resin band etc. can crooked ribbon.
In the present invention, overlapping is both sides about this intensity retaining member, by one-tenth lamination single-piece canvas such as cohesiveness rubber, constitute by being positioned at the most inboard internal layer canvas that exposes 2～5 layers of outside faces in its outside with surperficial canvas of guiding the moving contact of guide rail outer peripheral face into and lamination of handrail.And, in the 1st scheme, surperficial at least being made in this polylith canvas with the electric conductivity line, in the 2nd scheme, in surperficial canvas, inweave electric conductivity shoestring at least, so in arbitrary scheme, not only have good walking slickness, and have and prevent and guide into the effect that rail friction electrifies.
In the present invention's the 1st scheme, as the electric conductivity line, be not only the line that conducting fibre doubling or stranding are twisted, for example in the periphery that makes the syntheticfibres doubling or rub the synthetic thread of twisting with the hands, helical coil is around line of conducting fibre etc., and can use conducting fibre and the compound line of syntheticfibres.Wherein, as conducting fibre, except that carbon fiber, also can use at the thin metallo-fiber (commodity of for example high Lai Rangongshe system be called Metax) of syntheticfibres outer peripheral face plating, make conductive metal cmpd and syntheticfibres make chemically combined fiber (the commodity Sanderon by name of for example Japanese silkworm wool dyeing society system), wrap in fiber (for example the commodity of カ ネ ボ ウ society system are called Beftron) around the carbon particle etc. with syntheticfibres.
In such electric conductivity line, especially in the periphery helical coil in the line of conducting fibre, owing to vertically disposing conducting fibre at regular intervals with exposing, so at its exposed division if make ground connection (for example contact) with the connected to chassis conductor, can be directly total length by line make the charged particles dissipation.Thereby, using under the canvas situation that is made into such electric conductivity line, can limit to greatest extent because of the use conducting fibre makes material cost and rise, and improve anti-charged effect.
In the 1st scheme, through total length electric charge is dissipated with 1 place's ground connection in order to resemble as previously mentioned soon, preferably using specific insulation as the electric conductivity line is 1 * 10
5Below the Ω cm.
Also have in canvas with this electric conductivity line, may not make that institute is wired an electric conductivity, for example with the institute of vertical (working direction) arrangement in parallel of handrail wired in, make the electric conductivity line every 2～20mm, make and guide into the electric charge that rail friction produces, promptly vertically disperse to move, can eliminate through ground connection at handrail.
In the 2nd scheme, can use as electric conductivity shoestring metallic paper is cut into the body of faciola shape or the electroconductive resin that the conductive material that resembles metal-powder and toner body is cooperated, be configured as the body in garden shape or flat cross section.In addition, eliminate rapidly for 1 place's ground connection makes the electric charge on elongated, preferably using specific insulation is 1 * 10
6The material that Ω cm is following.
In the canvas that inweaves such electric conductivity shoestring, either direction and inweave electric conductivity shoestring with appropriate intervals can fully improve effect in length and breadth.Especially as with the vertical ordinate of (working direction) arrangement in parallel of handrail, when inweaving every 2～20mm under the electric conductivity ribbon situation, make because of vertically moving dispersion to handrail with the electric charge of guiding the rail friction generation into is very fast, eliminate through ground connection.
In the 1st and the 2nd scheme, as the laminated cohesiveness rubber layer that comprises the canvas of described electric conductivity line or electric conductivity shoestring, in poly-chloroprene rubber, government rubber, butyl rubber, second-third rubber (エ チ レ Application-プ ロ ピ レ Application go system) isopolarity or non-polar rubber, setting makes the anti-charged effect of handrail total length can keep the longer time to be semipermanent by adding the layer that mixing is formed as the conducting rubber of the electric conductivity extending agent of metal powders such as carbon black, aluminium, nickel, silver, carbon chopped fiber, stainless steel short fiber with this.
Promptly along with the walking of handrail, when electric conductivity line or electric conductivity shoestring by being cut off under the situation with guiding rail friction into, conducting (movement of electric charges) is interrupted, though lose the electric-charge-dissipating effect, but because of on the canvas back side of containing electric conductivity line or belt shape body, the conducting rubber layer being set, even if, also can keep conducting by the conducting rubber layer, the lasting effect of performance electric-charge-dissipating in total length so be breaking at electric conductivity line that the handrail inner surface exposes etc.Make under the canvas situation of electric conductivity line or electric conductivity shoestring in the part of certain intervals when using ordinate, by resembling this conducting rubber layer, owing to can become separated in flight instantaneous, so very easy to the elimination of electric conductivity line or belt shape body connected to chassis electric charge in the charged particles of the whole direction of handrail width.
Preferably using intrinsic volume resistance is 1 * 10
3～1 * 10
7The conducting rubber that the conduct of Ω cm is had that effect.Intrinsic volume resistance at conducting rubber surpasses 1 * 10
7During Ω cm, insufficient because of conducting electricity, replenish the electric charge removing that utilizes electric conductivity line or belt shape body so can not give full play to.When intrinsic volume resistance less than 10
3Under the Ω cm situation, then because intrinsic resistance descends, need do the interpolation of a large amount of electric conductivity extending agents, the mechanical characteristics of viscosity and stretch ratio etc. is descended, this is very undesirable.

Use in the handrail at the movable passageway of the embodiment that resembles this structure, horizontal line as surperficial canvas, because of inweaving conductive strips 12 every a determining deviation, so suppressing surperficial canvas and synthetic resin making rubs between guide rail electric charge takes place, simultaneously, the conductive strips 12 of the electric charge that makes generation by inweaving surperficial canvas disappear to guiding the rail-sides ground lug into promptly to the handrail side travel.Therefore electric charge is not put aside on handrail, so promptly be eliminated before human body sensory.
And, movable passageway at this embodiment is used in the handrail, compares with the manufacturing of the electric conductivity line 10 of coiling carbon fiber 9 on polyester line 8 peripheries, owing to can save the spinning of conducting fibre or the technology of twisting thread, so the shaping of conductive strips 12 is easy, can reduce the handrail manufacturing cost.In addition, conductive strips 12 compare with electric conductivity line 10, and durability is good, even if also do not cut off because of long-time the use, prevent charged effect so keep handrail sustainably.
Also the handrail of this embodiment is added on the circulating handrail experimental engine experimentally, implements continuous drive test in 1000 hours, decorate rubber layer surface charging magnitude of voltage and be everlasting below the 1000V, also do not have the electric shock sensation even contact hand.
In addition, in the above-mentioned the 1st and the 2nd embodiment, only surperficial canvas 5 is made at the vertical or laterally mixed at certain intervals canvas of knitting electric conductivity line 10 or conductive strips 12, but also can make such structure to whole canvas.As making the laminated single-piece rubber of the polylith canvas that comprises surperficial canvas 5, can use the conducting rubber that in polarity or nonpolar cohesiveness rubber, adds the electric conductivity extending agent.Like this, increased the anti-charged effect that is produced by electric conductivity line 10 or electric conductivity band 12, but and semipermanent keep anti-charging property by the handrail total length.
As mentioned above, at movable passageway of the present invention with in the handrail, at least at the most inboard surperficial canvas because of inweaving electric conductivity line or electric conductivity shoestring, so it is charged to prevent and guide into rail friction, the passenger who touches handrail does not have the electric shock unplessantness displeasure, can not make that to decorate rubber layer contaminated because of dust etc. adheres to.And the operation slickness is good, and tape transport is stable.
