Description

  The present invention relates to a passenger conveyor such as an escalator or an electric road, and relates to a step cleaning device that removes dirt in a groove on an upper surface of the step.

  Usually, regarding the cleaning of the groove provided on the step upper surface of the escalator, it is customary to perform the cleaning manually while the operation of the escalator is stopped. However, such manual cleaning requires a cleaning operation while sequentially moving over a number of steps, so that the work efficiency is low, and it takes a long time for cleaning maintenance, which impairs the convenience of the user. It was. In view of this, a step cleaning device has been proposed that cleans with a brush member while circulating the above steps (see, for example, Patent Document 1).

  Here, Patent Document 1 discloses a cleaning device configured to bring a rotating brush into contact with an upper surface of a step of an escalator, sweep out dust on the upper surface of the step with the rotating brush, and suck and remove the dust that has been swept out. Has been.

JP-A-8-133656

  However, the above prior art has the following problems. That is, in the cleaning device according to the above prior art document, the rotating brush is placed on the upper surface of the step, and dust on the contact surface is removed along with the movement of the step. Therefore, the step and the rotating brush move relatively. (The rotating brush is displaced with respect to the step groove), the contact pressure of the rotating brush tends to be unstable, and it is difficult to stably maintain the cleaning performance. In particular, the dirt that has adhered to the groove on the upper surface of the step is oil that is constantly dripping onto the step drive chain of the escalator to dirt, dust, etc. that adheres to the shoe sole of the escalator user, and dust that adheres to clothing. Etc. are often mixed and firmly adhered in the groove, and it is difficult in the first place to remove the adhered dirt in this way by suction as in the cleaning device according to the prior art. The above rotating brush, which is liable to be displaced with respect to the upper surface and the contact pressure is likely to be unstable, has a problem that dirt in the groove cannot be sufficiently removed.

  Further, along with the movement of the rotating brush, there has been a problem that the cleaning device and the peripheral member of the step come into contact with each other and damage the peripheral member such as scratches. In particular, the side guards (hereinafter also referred to as skirt guards) erected at both ends in the width direction of the step are provided with anti-slip processing on the surface from the viewpoint of improving safety for users, and are cleaned. If the anti-slip finish on the surface is peeled off due to contact with the device, for example, shoes for infants, etc. trying to grab the handrail will be sandwiched between the step and the skirt guard. There is a concern that safety may be impaired. Thus, the groove portions on both sides of the step still require separate cleaning work such as manual work.

  In view of the above-described problems of the prior art, the present invention provides a step cleaning device that can surely scrape and remove dirt adhered in the step groove at a low cost with a simple configuration. It is the purpose.

  In order to achieve the above object, a passenger conveyor step cleaning device according to the present invention is a step cleaning device for cleaning a step groove formed on a step upper surface of a passenger conveyor, and is movably attached around a rotation axis. A movable lever, a brush member provided on the distal end side of the movable lever, having a width substantially equal to the step, and disposed so that the distal end of the movable lever contacts the step groove, and the passenger conveyor On the other hand, while fixing the relative position of the rotating shaft of the movable lever, positioning fixing means for positioning the relative position of the brush member with respect to the step groove, and pressing for applying a pressing force for pressing the brush member into the step groove Means.

  In such a configuration, a pressing force can be applied to the brush member in a state in which the relative position with respect to the step groove is positioned, so that dirt fixed in the step groove can be stably removed with a simple configuration. It becomes possible.

  The pressing means may include a posture adjusting mechanism that adjusts the posture so that the pressing direction is always perpendicular to the installation surface.

  When configured in this way, the cleaning device can be installed so that the pressing force by the pressing means is always perpendicular to the arbitrary ground plane, so stable installation on any ground plane is possible. In addition, a predetermined pressing force can always be applied to the tip brush member regardless of the inclination of the ground contact surface.

  Furthermore, the brush member may include an excessive force preventing mechanism that secures a certain separation distance from the upper surface of the step and prevents an excessive pressure contact force from being applied to the step.

  When comprised in this way, the damage accompanying the excessive press-contact force with respect to a step or a brush member can be prevented beforehand.

  Further, the brush member is attached to a support member movable with respect to the movable lever, and the excessive force preventing mechanism maintains a predetermined posture of the brush member in cooperation with the support member. May be.

  When configured in this way, the excessive force prevention mechanism can also be used as a posture maintaining mechanism, thereby contributing to the reduction in the number of parts and the downsizing associated with the functional combination.

  Furthermore, the pressing means may be disposed on the opposite side of the brush member with the positioning fixing means interposed therebetween.

  In such a configuration, the pressing force applied to the brush member can be expanded by this principle, so that it is possible to omit a power source such as suction and rotation, and to reduce the size and cost of the apparatus and reduce noise. It can contribute to reduction.

  Further, the positioning and fixing means can be configured by fastening a support member that rotatably supports the rotating shaft to a comb plate in which a step groove enters and exits.

  When configured in this way, positioning and fixing of the step cleaning device that enables stable cleaning of the step groove can be easily realized by diverting the existing constituent members.

  According to the present invention, a step cleaning device that can prevent the positional deviation with respect to the step while maintaining the contact pressure of the brush member constant and reliably scrape and remove the dirt fixed in the step groove can be realized. And can be realized at low cost.

It is a schematic diagram. FIG. 4 is a schematic side view and a schematic plan view for explaining a schematic configuration of the step cleaning device according to the present embodiment.

  As schematically shown in FIGS. 2 to 4, the step cleaning device 1 according to the present embodiment includes a pair of movable levers 10, 10 formed movably around the rotation shaft 10 </ b> S, and the movable lever 10, 10 is provided with a brush member 20 provided at the tip of 10 and a pressing means 30 provided at the rear ends of the movable levers 10 and 10. In the present embodiment, a plurality of reinforcing ribs 10 r are disposed between the movable levers 10 and 10 in order to reinforce the mechanical strength of the movable levers 10 and 10. The step cleaning device 1 is fastened and fixed to the comb plate 110 of the escalator 100 with bolts.

  The pair of movable levers 10, 10 according to the present embodiment has a rotation shaft 10 </ b> S inserted through substantially the center thereof, and a pair of substantially L-shaped as positioning fixing means attached to the comb plate 110. The mounting brackets 10F and 10F are supported so as to be movable around the rotation shaft 10S.

Specifically, instead of the fixing screw provided at a predetermined position of the comb plate 110, a long device fixing screw 10B having the same diameter is penetrated through the bottom surface of the L-shaped mounting bracket 10F. inserted into hole 10F _0, so that the through mounting bracket 10F is fixed by screwing to the existing screw holes of the comb plate 110. Note that the through hole 10F ₀ of the mounting bracket 10F according to the present embodiment can correspond to an arbitrary mounting hole position of the comb plate 110 of the existing escalator 100 (step groove). It is formed as a long hole extending along a direction perpendicular to 100Sa.

  Then, by utilizing the existing comb plate 110 in this manner, the pair of movable levers 10 and 10 are movably supported via the pair of mounting brackets 10F and 10F that can be easily fixed to the comb plate 110, thereby the escalator. The relative position of the rotary shaft 10S (fulcrum) of the step cleaning device 1 is fixed with respect to 100, and positioning and fixing of the brush member 20 at the tip in the width direction can be easily performed. Thereby, it is possible to reliably prevent contact with peripheral members (for example, the skirt guard 109 standing at the end in the width direction) in step 100S during the cleaning operation.

  The brush member 20 according to the present embodiment is provided on the distal end side (the side facing the step 100S) of the pair of movable levers 10 and 10 and is attached to the movable levers 10 and 10 so as to be rotatable. Between the movable levers 10 and 10 via the support brackets 20F and 20F. Specifically, a substantially rectangular pedestal portion 21 having a width substantially the same as that of step 100S, and brush hairs arranged in a plurality of rows on the pedestal portion 21 at an interval equivalent to the interval of the step groove 100Sa facing the step 100S. 23, and the pedestal 21 and the movable levers 10 and 10 are connected via support brackets 20F and 20F.

  Further, a plurality (a pair) of roll stoppers 21R as an excessive force prevention mechanism are disposed behind the pair of support brackets 20F, 20F (pedestal portion 21), and the roll stoppers 21R are arranged on the upper surface of step 100S. By abutting, a certain separation distance is secured between the upper surface of the step 100S and the brush member 20, and the amount of biting into the step groove 100Sa of the brush bristles 23 at the tip is always maintained at a predetermined value. Even when an excessive pressure contact force (pressing force) is applied to the brush member 20, it is possible to prevent unexpected damage to the step groove 100Sa and the brush hair 23 at the tip.

  Further, the roll stopper 21R, together with the support bracket 20F configured to be movable, always keeps the posture of the brush member 20 relative to the step 100S in a predetermined posture (the bristles 23 are perpendicular to the upper surface of the step 100S). It is possible to maintain the posture. That is, the roll stopper 21R as an excessive force prevention mechanism according to the present embodiment also functions as a posture maintaining mechanism that maintains the posture of the brush member 20 constant.

  From the viewpoint of maintaining the posture of the brush member 20 stably by the cooperation of the support bracket 20F and the roll stopper 21R, the mounting position of the pair of support brackets 20F, 20F (the mounting position with respect to the movable lever 10), The support bracket 20F and the roll stopper 21R are arranged so as to be positioned substantially on the same straight line (on the straight line along the traveling direction of the step 100S) with the arrangement center of the corresponding pair of roll stoppers 21R, 21R. It is preferable.

  Further, in the present embodiment, the thickness and length of the brush bristles 23 can be arbitrarily set as appropriate from the viewpoint of surely scraping off dirt adhering in the step grooves 100Sa (for example, step grooves). Depth: 11 mm, step groove width: 6.0-8.5 mm, brush hair thickness: about φ0.5 mm, brush hair length: 20-30 mm).

Furthermore, since the brush member 20 according to the present embodiment is configured to be easily detachable via the support brackets 20F, 20F, the length and arrangement interval of the brush bristles 23 can be set to the step groove of the existing escalator 100. By preparing a plurality of types of brush members 20 set in advance according to the depth, arrangement interval, etc. of 100Sa, it can be easily applied to the cleaning of step 100S of existing types of escalators 100. For example, as schematically shown in FIG. 5, the brush member 20 having a short length of the brush bristles 231 at both ends is used for Step 100 </ b> S where both ends are high from the viewpoint of improving safety and the like. it makes it possible to clean the steps groove 100SA ₀ at both ends of the step 100S the risk of contact with the peripheral members caused more effectively.

  The pressing means 30 according to the present embodiment includes a posture adjustment angle 31 having a substantially L-shaped cross section as a posture adjustment mechanism disposed over the rear ends of the pair of movable levers 10 and 10, and the posture adjustment angle. 31 includes an adjustment bolt 35 screwed so as to penetrate the upper surface 31a of the 31 (perpendicular to the upper surface 31a), a compression spring 30S interposed at the tip of the adjustment bolt 35 via a plate 33, and the like. ing.

  More specifically, the posture adjusting angle 31 has end faces 31c formed at both ends in the width direction (a direction crossing between the movable levers 10 and 10) (both ends are closed by the end faces 31c). Then, the fastening bolt 32 is inserted into the end surface 31c and the movable lever 10 and fixed with a nut from the inside of the end surface 31c, so that the posture adjusting angle 31 is attached to be movable with respect to the movable lever 10. . The upper and lower ends of the compression spring 30S are sandwiched between a pair of a bottom plate 33d and an upper plate 33u, and the upper plate 33u is moved relative to the bottom plate 33d by rotating the adjustment bolt 35. By moving up and down, the compression force of the compression spring 30S can be adjusted.

  As described above, the compression spring 30S constituting the pressing means 30 is configured so as to be rotatable relative to the movable lever 10 together with the attitude adjustment angle 31, whereby the bottom plate 33d in which the compression spring 30S is interposed is formed. The escalator 100 can be brought into contact with an arbitrary installation surface in parallel (the compression spring 30S can be in a posture perpendicular to the arbitrary installation surface). Thereby, it can be installed on an arbitrary inclined surface, and a predetermined pressing force adjusted in advance by the adjustment bolt 35 is stabilized on the brush member 20 at the tip via the movable lever 10 regardless of the inclination of the installation surface. Can be granted.

  Further, since the brush member 20 and the pressing means 30 are disposed with the rotating shaft 10S interposed therebetween, the compression force (pressing force) by the compression spring 30S can be expanded and utilized by this principle, and the step A special drive source (for example, a power source such as brush rotation or suction) for removing dirt stuck in the groove 100Sa can be omitted, and the apparatus can be reduced in size, cost, and noise can be reduced with a very simple configuration. Can contribute.

  When attaching the step cleaning device 1 according to the present embodiment, the tip brush member 20 and the roll stopper 21R are brought into contact with the upper surface of the step 100S, and the bottom plate 33d of the pressing means 30 is placed on the installation surface (inclined surface). ) And then screwed to the comb plate 110 via the mounting brackets 10F and 10F, it can be easily mounted and fixed to the existing escalator 100. Further, the step cleaning device 1 according to the present embodiment may be installed on either the comb plate 110u on the upper entrance / exit 100U side or the comb plate 110d on the lower entrance 100D side.

  Further, at the time of cleaning, the escalator 100 is circulated in a predetermined direction (for example, a direction from the upper entrance / exit 100U toward the lower entrance / exit 100D). Thereby, the dirt scraped out by the brush member 20 is carried in a state of floating from the inside of the step groove 100Sa with the movement of the step 100S, and falls by its own weight at the place where the step 100S is reversed. Since this dirt is heavy, it is difficult to be scattered around the periphery. For example, by installing a collection container below the reversal part of Step 100S, it is possible to easily remove and collect the dirt in the step groove 100Sa.

  According to the step cleaning device 1 according to the present invention configured as described above, the brush member 20 at the tip can be pressed against the surface of the step 100S with a constant contact pressure in a state of being positioned and fixed with respect to the escalator. During the cleaning operation, the step cleaning device 1 stuck to the groove 100Sa formed on the surface of the step 100S while reliably preventing the peripheral member near the step 100S from coming into contact with the peripheral member and damaging the peripheral member. It becomes possible to remove dirt stably. At the same time, there is no need for a drive source (power supply, etc.) for rotating or suctioning the brush to clean and remove dirt stuck on the step 100S, contributing to energy savings and noise reduction. In addition, the cost can be greatly reduced with a simple configuration.

  The technical scope of the present invention is not limited to the above-described embodiments, and various changes or improvements can be added without departing from the scope of the present invention described in the claims. . For example, in the above-described embodiment, as an example of the passenger conveyor, the step cleaning device applied to the escalator 100 in which the step 100S moves in the vertical direction (inclination direction) is illustrated, but the step cleaning device according to the present invention is Of course, the present invention is not limited to such a form. For example, step 100S such as an electric road (moving sidewalk) can be naturally applied to a passenger conveyor that moves in the horizontal direction.
