Description

An embodiment of the present invention relates to a cleaning unit attachment device.

An escalator, which is an example of a passenger conveyor, moves while a plurality of connected steps (steps) transition between a stepless state and a stepped state. When using a passenger conveyor, it is desirable that users place their hands on or hold a handrail belt that moves in conjunction with the steps to support their posture and ensure safety during travel. However, since an unspecified number of users touch the handrail belt, it is desirable to frequently clean and disinfect the handrail belt for sanitary reasons. Therefore, various cleaning devices such as handrail sterilization devices have been proposed which are attached to handrail belts and enable cleaning and sterilization even during normal operation of the passenger conveyor. These cleaning devices, for example, generate electricity by pressing a roller against a running handrail belt and rotating the roller, drive the cleaning device, and irradiate the handrail belt with sterilizing light such as ultraviolet rays to disinfect and clean the handrail belt. running

However, when cleaning and sterilizing treatment is performed using a cleaning device of the type attached to a handrail belt as shown in the prior art, the sterilization device is placed within the reach of the user of the passenger conveyor, the person in charge of cleaning, etc. Since it is installed, there is a possibility that fingers may be caught between the sterilization device and the handrail belt. Therefore, sufficient safety measures must be taken for the cleaning device of the type attached to the handrail belt. Therefore, if it is possible to provide a cleaning unit mounting device that can reliably avoid the risk of fingers being caught in a simple structure, it is significant in terms of improving safety and reducing running costs.

An embodiment cleaning unit attachment includes a support arm and a roller. The support arm can be attached to a position above the center of the curve of the curved portion of the boarding/alighting section of the passenger conveyor, in the support body that supports the handrail belt that moves in conjunction with the moving body that moves along the movement path of the passenger conveyor. It is swingable in the direction of travel and in the reverse direction of travel of the handrail belt with projections projecting away from the surface of the belt. A roller is fixed to the side of the support arm remote from the pivot center and is capable of contacting the surface of the handrail belt. The roller rotates when it comes into contact with the moving handrail belt, and generates driving force for a cleaning unit supported by the support arm to clean the handrail belt. When a foreign object is inserted between the handrail belt and the roller, the roller swings in a first direction away from the handrail belt. oscillate in one direction.

FIG. 2 is an exemplary and schematic front view of a moving path viewed from a boarding/alighting position of an escalator as an example of a passenger conveyor, showing a state in which the cleaning unit mounting device of the embodiment is mounted. FIG. 3 is an exemplary and schematic side view showing the detailed structure of the cleaning unit mounting device of the embodiment. FIG. 4 is an exemplary and schematic top view showing the configuration of the cleaning unit mounting device of the embodiment.

Below, the cleaning unit mounting device according to the embodiment will be described in detail based on the drawings. Components in this embodiment include those that can be easily replaced by those skilled in the art, or those that are substantially the same, and the present invention is not limited by the following embodiments.

FIG. 1 is an exemplary and schematic side view of the vicinity of a boarding/alighting position 14 of an escalator 12 as an example of a passenger conveyor, showing a state in which a cleaning unit mounting device 10 of an embodiment is mounted. Also, FIG. 2 is an exemplary and schematic front view of the moving path when viewed from the boarding/alighting position 14 of the escalator 12 showing the state where the cleaning unit mounting device 10 is mounted.

The escalator 12 operates by circularly moving a plurality of steps 16 (moving bodies) that are connected in an endless manner, thereby conveying objects such as users and luggage between the upper and lower floors. A moving path 16a is constructed. The escalator 12 may move between the entrance side and the exit side on the same floor to carry users, luggage, and the like.

Under the floor of the boarding/alighting position 14 (boarding/alighting plate) of the escalator 12, a drive mechanism for rotating the steps 16 is accommodated. The drive mechanism of the escalator 12 mainly includes a motor as a drive source, a speed reducer, a drive chain, a drive sprocket, a driven sprocket, and a step chain. The motor and speed reducer constitute a driving device. The motor is provided, for example, on the upper floor side. A speed reducer is attached to the output shaft of the motor. The speed reducer reduces the rotation of the motor and amplifies the rotational torque of the motor. A reduction sprocket is provided on the output shaft of the reduction gear and has a plurality of teeth. The drive chain is formed in an endless shape and extends over the reduction sprocket and the drive sprocket. The drive chain rotates the drive sprocket by circulating around the drive sprocket and the reduction sprocket by the driving force of the motor transmitted through the speed reducer. That is, the drive chain transmits the driving force of the motor transmitted through the speed reducer to the drive sprocket. The drive sprocket has a plurality of teeth that mesh with the step chain and is rotated by drive power from a drive controlled by the control board. The escalator 12 drives a step chain stretched between a driving sprocket and a driven sprocket to circularly move a plurality of steps 16 connected in an endless manner and to run the plurality of steps 16.例文帳に追加

The escalator 12 has balustrades on both sides (both sides of the movement path 16a) of the plurality of steps 16 in the traveling direction. The balustrade includes a handrail belt 18 that can be used by a user or the like to hold while moving the steps 16 or place a hand on the step 16 to stabilize the posture. Specifically, the balustrade mainly consists of a skirt guard panel, an inner deck, a balustrade panel 20, and a handrail belt 18 running on a handrail rail provided on the balustrade deck provided at the outer edge of the balustrade panel 20. , consists of The skirt guard panels are adjacent on both sides in a direction (width direction) orthogonal to the running direction of the plurality of steps 16 (e.g., the descending direction and ascending direction in which the escalator 12 operates), and are adjacent to the entrance on the upper floor side. It is provided between the entrance on the lower floor side. An inner deck is attached to the upper side of the skirt guard panel. A balustrade panel 20 made of, for example, a transparent or translucent member such as a glass plate or a metal plate such as stainless steel is attached to the upper side of the inner deck. A handrail belt 18 is movably fitted to a handrail rail attached to the outer periphery of the balustrade panel 20.例文帳に追加The handrail belt 18 is circularly moved by a handrail belt driving chain that is circularly driven in synchronism with the step chain, for example, advances from the inlet 22 on the lower floor side and enters the inlet 22 on the upper floor side. The step 16 and the handrail belt 18 rotate in the same direction in synchronization (interlocking).

As described above, the escalator 12 configured in this manner is used by an unspecified number of users, and the users often touch the handrail belt 18 . Therefore, it is desirable to clean or disinfect the belt surface 18s of the handrail belt 18 regularly or frequently so that the escalator 12 can be used with peace of mind. Therefore, the cleaning unit mounting device 10 of this embodiment has a configuration that can be permanently mounted on the running handrail belt 18 and can be easily attached and detached. In addition, when the user holds the handrail belt 18 or puts his or her finger on the handrail belt 18, the cleaning unit mounting device 10 causes the finger to be caught inside the cleaning unit mounting device 10 together with the handrail belt 18. In order to prevent the handrail belt 18 from slipping or to reduce the risk of fingers being caught, the handrail belt 18 is provided with a structure that can swing in the moving direction and the reverse moving direction. That is, it has a safety mechanism.

3 and 4 in addition to FIGS. 1 and 2, the detailed structure of the cleaning unit mounting device 10 will be described. FIG. 3 is an exemplary and schematic side view showing the detailed structure of the cleaning unit mounting device 10. As shown in FIG. 4 is an exemplary and schematic top view showing the configuration of the cleaning unit mounting device 10. As shown in FIG.

The cleaning unit mounting device 10 includes a pair of support arms 24 that mount the cleaning unit mounting device 10 to a balustrade panel 20 that is an example of a support for the handrail belt 18 of the escalator 12 . As shown in FIGS. 1 and 2, the pair of support arms 24 are provided at the balustrade curved portion 20a (belt curved portion) of the balustrade panel 20 (support) that supports the handrail belt 18 at the boarding/alighting position 14 (mounting portion) of the escalator 12. It is mounted at a position above the center of curvature S of the portion 18a) (above the horizontal line r in FIG. 1). As shown in FIG. 3, the support arm 24 can be fixed to the balustrade panel 20 by a fixing member 26 such as a bolt, and can move in the moving direction and the reverse moving direction of the handrail belt 18 about the pivot center 28 as the central axis. It is possible to swing to For example, in FIG. 1, when the handrail belt 18 (step 16) moves in the direction of arrow A, the support arm 24 can swing in the direction of arrow B as the direction of movement, and in the direction of arrow C in FIG. 3 as the direction of reverse movement. It is possible to swing to For example, a bearing or the like is arranged at the swing center so that the support arm 24 can be easily swung (rotated). That is, since the support arm 24 is fixed to the balustrade panel 20, the moving handrail belt 18 continuously passes through the support arm 24 (the cleaning unit mounting device 10).

Further, the support arm 24 protrudes in a direction away from the belt surface 18s of the handrail belt 18 when the cleaning unit mounting device 10 is installed at a predetermined position (a position above the curved center S of the balustrade curved portion 20a). and a protruding portion 24a. A roller 30 capable of coming into contact with the belt surface 18s of the handrail belt 18 is arranged inside the projecting portion 24a (inside the cleaning unit mounting device 10), that is, on the side away from the swing center 28 of the support arm 24. there is The roller 30 can be driven to rotate by contact with the handrail belt 18 . The roller 30 functions as a rotor of a generator, and generates electricity by rotating. The generated electric power drives the cleaning unit 32 built in the cleaning unit mounting device 10 . The cleaning unit 32 can be, for example, an ultraviolet generator that emits ultraviolet light having a sterilizing effect. Ultraviolet light is emitted from, for example, an ultraviolet LED 32a arranged at a position facing the handrail belt 18, and disinfects the belt surface 18s passing through the irradiation area. The rollers 30 may be brought into contact with the handrail belt 18 to catch and remove dust and the like adhering to the handrail belt 18 . The removed dust may be collected by a collection section provided in the cleaning unit mounting device 10 .

As described above, the roller 30 serves as a drive source for the cleaning unit 32, so it is desirable that the roller 30 can efficiently generate power. Therefore, the surface of the roller 30 may be made of, for example, a flexible rubber material as an anti-slip member so that the surface of the roller 30 can rotate efficiently without slipping when it comes into contact with the handrail belt 18 .

In order to allow the roller 30 to generate power more efficiently, a weight 34 may be attached to a position shifted in the direction of the handrail belt 18 from the swing center 28 of the support arm 24, for example, at the tip of the projecting portion 24a. . The weight 34 generates an urging force that swings (rotates) the support arm 24 in a direction (the direction of arrow C in FIG. 3: a second direction described later) to approach the handrail belt 18 . The roller 30 supported by the support arm 24 is pressed by the handrail belt 18 due to the urging force of the weight 34, so that the roller 30 can rotate more efficiently to generate power. As will be described later, the weight of the weight 34 is such that when a foreign object such as a finger comes into contact with the roller 30, it resists the biasing force of the weight 34 and is supported without or with reduced damage to the finger or the like. A weight that allows the arm 24 to swing can be set in advance based on a test or the like.

The operation of the cleaning unit mounting device 10 configured in this manner will be described first with reference to FIG.

As shown in FIG. 1, when the escalator 12 (handrail belt 18) is running in the direction of arrow A, a foreign object Fma (for example, a user's finger) is removed from the downstream side (lower surface side) of the cleaning unit mounting device 10. is inserted between the cleaning unit mounting device 10 and the handrail belt 18 . As described above, since the support arm 24 can swing about the swing center 28 (see FIG. 3), the foreign matter Fma is easily pushed up by the support arm 24, and the cleaning unit mounting device 10 moves toward the arrow B. direction. As described above, the support arm 24 is mounted at a position above the bending center S of the balustrade curved portion 20a of the balustrade panel 20 (support body) (above the horizontal line r in FIG. 1), as shown in FIG. It is Therefore, when the support arm 24 rotates in the direction of arrow B, the roller 30 swings (moves) in a direction away from the handrail belt 18 (first direction) as indicated by the dashed line in FIG.

As a result, even if a foreign object Fma (for example, a finger) is in contact with the handrail belt 18 and enters the interior of the cleaning unit mounting device 10 (between the handrail belt 18 and the roller 30), the handrail belt 18 and Since the gap between the rollers 30 is enlarged, the risk of being pinched and strongly pressed can be reduced. In addition, it becomes easier for the user to recognize the danger during the operation time during which the cleaning unit mounting device 0 (the support arm 24) rotates, and it is easier for the user to take an evasive action (the action of releasing the fingers from the handrail belt 18). can do. In other words, it is possible to provide a cleaning unit mounting device that has a simple structure and is capable of reliably avoiding the risk of fingers being caught.

Next, as shown in FIG. 1, when the escalator 12 (handrail belt 18) is running in the direction of arrow A, foreign matter Fmb (for example, user's A finger, etc.) is inserted between the cleaning unit mounting device 10 and the handrail belt 18. FIG. In this case, since the handrail belt 18 moves away from the cleaning unit mounting device 10, the foreign matter Fmb (for example, the user's finger) is drawn between the handrail belt 18 and the cleaning unit mounting device 10. Not likely. Even in such a case, even if the foreign matter Fmb approaches and is inserted, as described above, the support arm 24 can swing around the swing center 28 (see FIG. 3), and the roller 30 is also rotatable. Therefore, even if the foreign matter Fmb contacts the roller 30, the roller 30 rotates (rotates) while contacting the surface of the foreign matter Fmb, and is pushed up by the intruding foreign matter Fmb. swing to. That is, the support arm 24 can be easily pushed up in the arrow B direction. Therefore, the roller 30 supported by the support arm 24 mounted at a position above the curved center S of the curved portion 20a of the balustrade panel 20 (support body) (above the horizontal line r in FIG. 1) is the handrail belt 18. It swings (moves) in a direction away from (first direction).

As a result, even if a foreign object Fmb (for example, a finger) enters the inside of the cleaning unit mounting device 10 (between the handrail belt 18 and the roller 30) from the upstream side of the handrail belt 18, Since the gap is enlarged, it is possible to reduce the risk of fingers being pinched and strongly pressed. In addition, it becomes easier for the user to recognize the danger during the operation time when the cleaning unit mounting device 10 (support arm 24) rotates, and it is easier for the user to take an evasive action (the action of releasing fingers from the handrail belt 18). can do. In other words, it is possible to provide a cleaning unit mounting device that has a simple structure and is capable of reliably avoiding the risk of fingers being caught.

Next, consider a case where the support arm 24 (cleaning unit mounting device 10) swings in the direction of arrow B due to the foreign matter Fma or the foreign matter Fmb, and then the foreign matter Fma or the foreign matter Fmb is removed. As described above, the cleaning unit mounting device 10 (supporting arm 24) is arranged so that the balustrade panel 20 (supporting body) that supports the handrail belt 18 is positioned at the boarding/alighting position 14 (boarding/alighting portion) of the escalator 12. It is installed at a position above S (above horizontal line r in FIG. 1). Therefore, when the foreign matter Fma and the foreign matter Fmb are removed, the support arm 24 is It swings in the direction of the arrow C in FIG. 3 and automatically returns to the state before the insertion of the foreign object. That is, the roller 30 is swung in the second direction to contact the belt surface 18s of the handrail belt 18 . Therefore, the cleaning unit mounting device 10 returns to a state in which cleaning and sterilization can be performed. Further, the rollers 30 are restored to a state capable of generating electricity, and the movement of the handrail belt 18 enables the cleaning unit 32 to resume operation.

As described above, the cleaning unit mounting device 10 of the present embodiment has a simple structure, and can reliably avoid the risk of fingers being caught. It is possible. Therefore, it is not necessary for the manager of the escalator 12 to restore the cleaning unit mounting device 10, and the permanent cleaning unit mounting device 10 can be operated smoothly. A sensor is provided at any position of the support arm 24 to detect that the support arm 24 has swung (rotated) by a predetermined angle or more, or that the support arm 24 has returned to a position (orientation) that allows cleaning and disinfection. , the detection result may be acquired. The acquired detection result may be recorded in the cleaning unit mounting device 10 or transmitted to the control panel of the escalator 12, the management system of the escalator 12, or the like. The detection result can be used for analysis of a time zone in which insertion of foreign matter Fma or Fmb is likely to occur, countermeasures for avoiding the insertion itself, and the like.

As shown in FIGS. 3 and 4, brushes, for example, brushes, which extend toward the handrail belt 18 and have flexibility to block the contact position between the roller 30 and the handrail belt 18, are placed in front of and behind the roller 30 as shown in FIGS. 36 may be provided. The brush 36 prevents the foreign matter Fma, the foreign matter Fmb, etc. from entering between the handrail belt 18 and the roller 30, and gives an appropriate stimulus and uncomfortable feeling when it comes into contact with a finger or the like like a brush or the like. With this configuration, the user of the escalator 12 can easily and quickly recognize that the cleaning unit mounting device 10 is mounted and be careful not to touch the cleaning unit mounting device 10.例文帳に追加Also, by arranging the flexible brush 36 so as to contact the belt surface 18s of the handrail belt 18, it is possible to easily prevent dust and the like from entering the inside of the cleaning unit mounting device 10. FIG. As a result, the cleaning unit mounting device 10 itself can also be prevented from being soiled.

In the case of the cleaning unit mounting device 10 of this embodiment, as shown in FIG. ing. As a result, it becomes easier to effectively avoid the foreign matter Fma, the foreign matter Fmb, and the like from reaching the roller 30 . Further, as shown in FIGS. 3 and 4, the brushes 36c may be arranged on both lateral sides of the handrail belt 18. FIG. By arranging the brush 36 c to the side of the handrail belt 18 , it is possible to prevent the foreign matter Fma, the foreign matter Fmb, etc. from entering between the support arm 24 and the handrail belt 18 . In this case, it is easy to avoid pinching of the user's fingers, etc., and foreign matter such as dust is caught between the support arm 24 and the handrail belt 18, preventing the support arm 24 from sliding smoothly. can be easily prevented. That is, it is possible to facilitate the guarantee of the swing operation of the cleaning unit mounting device 10 .

As described above, the passenger conveyor to which the cleaning unit mounting device 10 of the present embodiment is applied has, as an example, an inclined moving path 16a connected to the upper floor and the lower floor, and has a step. A typical escalator 12 is shown with steps 16 moving in a holding state. The cleaning unit mounting device 10 may be mounted on the balustrade panel 20 (support) at a position above the bending center S of the balustrade curved portion 20a (above the horizontal line r), and is suitable for other types of passenger conveyors. A similar effect can be obtained by applying it. For example, the cleaning unit mounting device 10 of the present embodiment may be applied to an escalator in which the step 16 transitions to a horizontal state in the middle of the moving path 16a and then transitions to a stepped state again. Also in this case, the same effects as in the above-described embodiment can be obtained. In addition, each step 16 moves in a flat state without forming a step on the moving path 16a connecting the floor on the upper floor and the floor on the lower floor and the moving path 16a connecting the entrance side and the exit side of the same floor. The cleaning unit mounting device 10 of this embodiment may be applied to a so-called "moving walkway". Also in this case, the same effects as in the above-described embodiment can be obtained.

Further, in the above-described embodiment, the cleaning unit 32 is of a type that uses ultraviolet light to sterilize, but the cleaning and sterilization method can be changed as appropriate. For example, it may be of a type that sprays a sterilizing liquid or alcohol that has a sterilizing effect, or it may be of a type that sterilizes by heat. In addition, the cleaning unit 32 includes a device for wiping off the sprayed liquid or the like and a cooling device for returning the heated handrail belt 18 to room temperature so as not to cause discomfort when the user touches the handrail belt 18 by sterilization treatment. may be provided.
