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 have been proposed that enable cleaning and sterilization of the handrail belt. These cleaning devices perform disinfection by, for example, contacting a running handrail belt with a roller coated with a disinfectant solution, spraying the disinfectant solution, or irradiating light with a sterilizing effect. These cleaning devices are placed at a position where the fingers of the user cannot reach, for example, in order to prevent the fingers of the user who are holding or placing the hand on the handrail belt of the passenger conveyor from being caught in the cleaning device. , was installed inside the truss, etc. In addition, such a cleaning device has a safety device or the like electrically connected to the control panel of the passenger conveyor.

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.

<First embodiment>
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 the cleaning unit mounting device 10 of the first embodiment is mounted. FIG. 2 is an exemplary and schematic top view of the handrail belt 18 of the escalator 12 with the cleaning unit mounting device 10 of the first embodiment mounted, as viewed from above.

The escalator 12 operates by circulating (circulating) a plurality of steps 16 (moving bodies) that are connected in an endless manner, thereby moving objects such as users and luggage between upper floors and lower floors. A moving path 16a for conveying 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 fingers on the handrail belt 18, the cleaning unit mounting device 10 prevents the user's fingers from being caught inside the cleaning unit mounting device 10 together with the handrail belt 18. Equipped with a risk reduction structure that can reduce the risk of being strongly pressed in the event of being caught. That is, it has a safety mechanism.

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 . The support arms 24 are a pair of arms that can hold the handrail belt 18 in the width W direction, and have protrusions 24a that protrude in a direction away from the belt surface 18s of the handrail belt 18 . Further, a cleaning unit 26 is provided at the tip of the pair of support arms 24 (on the far side from the belt surface 18s of the handrail belt 18). In the case of the cleaning unit mounting device 10 shown in FIG. 2 , the cleaning unit 26 can take the first posture in which the cleaning unit 26 faces the belt surface 18 s of the handrail belt 18 . Further, the cleaning unit 26 rotates around the tip of one of the pair of support arms 24, that is, one end of the handrail belt 18 in the width direction, and separates from the belt surface 18s of the handrail belt 18. You can take two positions. That is, the cleaning unit 26 can pivot and move between the first posture and the second posture. Then, the cleaning unit 26 can clean (mainly disinfect) at least the belt surface 18s of the handrail belt 18 in the first posture.

The pair of support arms 24 are attached, for example, to a part of the balustrade curved portion 20a (belt curved portion 18a) at the boarding/alighting position 14 (boarding/alighting portion) of the escalator 12 of the balustrade panel 20 (support) that supports the handrail belt 18. can do. As described above, the cleaning unit 26 is pivotally moved from the first posture to the second posture, so that the support arm 24 (cleaning unit mounting device 10) is attached to the balustrade panel 20 (supporting arm) supporting the handrail belt 18. of the escalator 12 (below the horizontal line r in FIG. 1) below the curved center s of the balustrade curved portion 20a (belt curved portion 18a) or at a substantially horizontal position. be done.

As shown in FIG. 2, the cleaning unit 26 is rotatably supported by the projecting portion 24a of one of the pair of support arms 24. As shown in FIG. The protruding portion 24a of the other support arm 24 of the pair of support arms 24 can be attracted by an attraction member 28 (for example, a magnet) provided in the cleaning unit 26. As shown in FIG. In other words, when the cleaning unit 26 approaches (faces) the belt surface 18s of the handrail belt 18, the adsorption member 28 sticks to the projecting portion 24a. As a result, the cleaning unit 26 is fixed to the pair of support arms 24 (a state in which cleaning and sterilization can be performed). Also, when a foreign object (for example, a user's finger or the like) is inserted between the belt surface 18s and the cleaning unit 26, the attraction member 28 moves away from the support arm 24, thereby preventing the belt surface 18s and the cleaning unit 26 from being separated from each other. The space between them expands. As a result, it becomes easier to avoid pressure on the fingers or the like by the belt surface 18s and the cleaning unit 26 . A detailed structure of the cleaning unit mounting device 10 that can realize safe operation by rotating the cleaning unit 26 will be described.

FIG. 3 is an exemplary and schematic top view showing the detailed structure of the safety mechanism of the cleaning unit mounting device 10 of the first embodiment.

As described above, the cleaning unit mounting device 10 of the first embodiment is movable between the first position facing the belt surface 18s of the handrail belt 18 and the second position away from the belt surface 18s. be. In order to achieve the first and second postures, the cleaning unit 26 has a cleaning unit main body 26M, a first adsorption member 28A, a first sliding member 30, a second A sliding member 36 and the like are provided. One support arm 24B (second support arm) of the pair of support arms 24 includes a rotation shaft 40 formed at the tip of the projecting portion 24a and a third rotation shaft 40 connected to the rotation shaft 40. A sliding member 42 is provided.

The base member 26A is a base made of, for example, resin or metal, and has a flat surface. A member 36 and the like are provided. Also, the third sliding member 42 is slidable on the plane portion of the base member 26A.

The cleaning unit main body 26M can be, for example, a well-known ultraviolet generator that emits ultraviolet light having a sterilizing effect. Ultraviolet light is emitted from, for example, an ultraviolet LED arranged at a position facing the handrail belt 18, and disinfects the belt surface 18s passing through the irradiation area. The cleaning unit main body 26M may be driven by a built-in battery or may be driven by power supply from the escalator 12 side. Alternatively, a roller that contacts the handrail belt 18 and is driven to rotate may be provided, and the cleaning unit main body 26M may be driven by electric power generated by the rotation of the roller. The cleaning unit main body 26M is arranged at a position other than the flat surface of the base member 26A, for example, inside the base member 26A (a position shifted in the depth direction of the paper surface of FIG. 3, etc.) as long as the belt surface 18s can be irradiated with ultraviolet light. may be

The first attraction member 28A is, for example, a magnet, and is fixed at a position facing the support arm 24A (first support arm) of the pair of support arms 24 (part of the side surface of the base member 26A in FIG. 3). It is The first adsorption member 28A has an insertion hole 28h through which a release pin 32 (protrusion) provided at the tip of the first sliding member 30 can be inserted. The adsorption force of the first adsorption member 28A, which will be described later, facilitates support when, for example, a foreign object (for example, a finger of the user of the escalator 12) is inserted between the belt surface 18s and the cleaning unit 26. It is set to such an extent that it can be separated from the projecting portion 24a of the arm 24A. The attraction force (magnetic force) of the first attraction member 28A can be determined in advance by testing or the like.

The first sliding member 30 has a release pin 32 at one end thereof which can advance and retreat through the insertion hole 28h of the first adsorption member 28A, and a flange portion 30a at the base of the release pin 32. As shown in FIG. Further, the other end side of the first sliding member 30 is provided with an engaging groove 30b into which an engaging pin 38 provided at one end of the second sliding member 36 can enter. The first sliding member 30 is, for example, a rod-shaped member such as a cylinder or prism, and is slidably supported in the directions of arrows A1 and A2 by a supporting member 26t fixed on the flat surface of the base member 26A. . A compression spring, for example, is arranged as the biasing member 34 between the flange portion 30a and the support member 26t. Therefore, the first sliding member 30 is biased in the direction of arrow A2 by the biasing member 34, the release pin 32 passes through the insertion hole 28h of the first attracting member 28A, and is released from the first attracting member 28A. It is configured to be able to protrude. In other words, the first adsorption member 28A is urged to protrude in a direction separating from the support arm 24A (protruding portion 24a) to which the first adsorption member 28A is adsorbed. As a result, the cleaning unit 26 can be moved to the second posture away from the belt surface 18s. It should be noted that during the cleaning and disinfecting process by the cleaning unit mounting device 10, the first sliding member 30 is pushed in the direction of the arrow A1 against the biasing force of the biasing member 34, and the engagement pin 38 is inserted into the engagement groove 30b. is engaged. That is, the release pin 32 is in a non-protruding state from the surface of the first adsorption member 28A, the first adsorption member 28A is adsorbed to the projecting portion 24a of the support arm 24A, and the cleaning unit 26 faces the belt surface 18s. It is configured to maintain the posture of

The second sliding member 36 is, for example, a rod-shaped member such as a cylinder or prism, and is substantially orthogonal to the first sliding member 30 by a supporting member 26t fixed on the flat surface of the base member 26A. It is slidable in the direction (directions of arrows B1 and B2). The second sliding member 36 has an engaging pin 38 on one end side that can be engaged with the engaging groove 30b formed on the other end side of the first sliding member 30 as described above. Further, the other end of the second sliding member 36 is provided with a guiding pin 36a that can be inserted into, for example, a groove-shaped guiding portion 42b formed on the third sliding member 42 . The guide pin 36a is, for example, a cylindrical pin, and the guide portion 42b is, for example, an elongated hole-shaped groove having a width slightly wider than the diameter of the guide pin 36a. The second sliding member 36 slides in the directions of arrows B1 and B2 while being supported (guided) by the supporting member 26t by moving the guiding pin 36a while being guided by the guiding portion 42b. As a result, the second sliding member 36 is at the first position where the tip 32a of the release pin 32 at the tip of the first sliding member 30 protrudes from the insertion hole 28h of the first attracting member 28A. It is possible to move between an engagement position for engagement and a non-engagement position for allowing the release pin 32 to slide from the insertion hole 28h to a second position in which it is in a non-protruding posture.

One support arm 24B of the pair of support arms 24 is provided with the pivot shaft 40 formed at the tip of the projecting portion 24a, as described above. A supporting portion 44 fixed to one end of a third sliding member 42 is pivotally supported on the rotating shaft 40 . The support portion 44 may include a ball bearing, a dry bearing, or the like surrounding the rotating shaft 40 . The support portion 44 and the third sliding member 42 may be integrally formed, or may be joined using joining means such as welding. The support portion 44 pivotally supported by the rotating shaft 40 and the third sliding member 42 joined to the support portion 44 are slidable on the flat portion of the base member 26A in the directions of arrows A1 and A2. As described above, since the support arm 24 is fixed to the balustrade panel 20, the cleaning unit 26 (base member 26A) is configured to be relatively movable in the directions of arrows A1 and A2 with respect to the support arm 24B. there is As will be described later, the cleaning unit 26 (the base member 26A) moves relative to the support arm 24B when foreign matter is inserted between the belt surface 18s and the cleaning unit 26, for example.

The third sliding member 42 is, for example, a rod-shaped member such as a cylinder or prism, and is slidably guided in the directions of arrows A1 and A2 by a support member 26t fixed on the flat surface of the base member 26A. . In addition, a flange portion 42a is formed in a substantially intermediate region in the axial direction of the third sliding member 42, and a second end portion (end portion on the side opposite to the support portion 44) is formed at the tip of the flange portion 42a. A groove-shaped guiding portion 42b into which the guiding pin 36a of the sliding member 36 is inserted is formed. The guide portion 42b is formed in an oblique posture so as to move away from the engagement pin 38 as it moves away from the support portion 44 in the direction of the arrow A1. A compression spring, for example, is arranged as the biasing member 46 between the flange portion 42a and the support member 26t. Therefore, the third sliding member 42 is urged in the direction of arrow A1 during normal operation. When the third sliding member 42 is urged (moved) in the arrow A1 direction, the guiding pin 36a of the second sliding member 36 in the guiding portion 42b is positioned closer to the supporting portion 44 (see FIG. 3). position). As a result, the second sliding member 36 is guided in the direction of the arrow B1, and the engaging pin 38 becomes engageable with the engaging groove 30b of the first sliding member 30. As shown in FIG.

On the other hand, when the cleaning unit 26 (base member 26A) moves in the arrow A1 direction relative to the support arm 24B, the third sliding member 42 moves in the arrow A2 direction relative to the base member 26A. Become. As a result, the guide pin 36a of the second slide member 36 supported on the flat surface of the base member 26A moves within the guide portion 42b, and the end of the third slide member 42 farther from the support portion 44 moves. move to the department. That is, the second sliding member 36 moves in the arrow B2 direction. As a result, the engaging pin 38 of the second sliding member 36 is pulled out from the engaging groove 30b of the first sliding member 30. As shown in FIG. In this case, the first sliding member 30, which is biased in the direction of arrow A2 by the biasing member 34, moves in the direction of arrow A2 due to the disengagement between the engagement pin 38 and the engagement groove 30b. Slide (move). Then, the release pin 32 is protruded from the first adsorption member 28A, and the connection with the support arm 24A by the adsorption force of the first adsorption member 28A is released. As a result, the cleaning unit 26 becomes rotatable around the rotation shaft 40 . That is, the handrail belt 18 is allowed to shift to the second position away from the belt surface 18s. That is, the safety mechanism of the cleaning unit mounting device 10 operates.

Details of the operation of the safety mechanism of the cleaning unit mounting device 10 of the first embodiment configured as described above will be described with reference to FIGS. 4A to 4D. 4B to 4D show operations when the foreign object Fm is inserted at a position close to the rotation shaft 40. FIG. FIG. 4A is an exemplary and schematic top view showing the state before the safety operation of the safety mechanism of the cleaning unit mounting device 10 is started. FIG. 4B is an exemplary and schematic top view showing a first state (a state in which the engagement pin 38 is removed) during safety operation. FIG. 4C is an exemplary and schematic top view showing the second state (the sliding state of the first sliding member 30) during safety operation. FIG. 4D is an exemplary and schematic top view showing the state of completion of safety operation (completion of opening operation).

The state of the safety mechanism in FIG. 4A before the start of the safety operation is the same as the state shown in FIG. 42 exists at a position relatively moved in the direction of arrow A1 with respect to base member 26A. That is, the guiding portion 42b of the third sliding member 42 guides the guiding pin 36a of the second sliding member 36 toward the supporting portion 44 (the side closer to the engaging pin 38). As a result, the engaging pin 38 of the second sliding member 36 moves to a position where it can be engaged with the engaging groove 30b of the first sliding member 30, and resists the biasing force of the biasing member 34, thereby moving the first sliding member 36 toward the engaging groove 30b. prevents the sliding member 30 from moving in the direction of the arrow A2. That is, the release pin 32 of the first sliding member 30 does not protrude from the first adsorption member 28A. As a result, the first attracting member 28A can be attracted to the protruding portion 24a of the support arm 24A, and the cleaning unit 26 (cleaning unit main body 26M) is placed in the first posture facing the belt surface 18s of the handrail belt 18. maintain. In this state, the belt surface 18s can be cleaned and disinfected by the cleaning unit main body 26M.

Next, as shown in FIG. 4B, consider a case where a foreign object Fm (for example, a user's finger or the like) is inserted between the cleaning unit 26 (cleaning unit main body 26M) and the belt surface 18s. In this case, the cleaning unit 26 (base member 26A) moves in the direction of the arrow A0 against the biasing force of the biasing member 46 due to the foreign matter Fm. As a result, the support portion 44 and the third sliding member 42 pivotally supported by the rotation shaft 40 provided on the support arm 24B fixed to the balustrade panel 20 move relative to the base member 26A as indicated by the arrow A2. will move in the direction That is, the guiding portion 42b of the third sliding member 42 guides the guiding pin 36a of the second sliding member 36 to the far side from the support portion 44 (the far side from the engaging pin 38). As a result, the second sliding member 36 moves in the direction of arrow B<b>2 and the engaging pin 38 is extracted from the engaging groove 30 b of the first sliding member 30 .

In this case, as shown in FIGS. 4C and 4D, the first sliding member 30 moves in the direction of arrow A2 due to the biasing force of the biasing member 34 and is released from the insertion hole 28h of the first attracting member 28A. A tip portion 32a of the pin 32 protrudes. As a result, the cleaning unit 26 (base member 26A) is forced to detach from the projecting portion 24a of the support arm 24A against the adsorption force of the first adsorption member 28A, and rotates in the direction of arrow C in FIG. 4D. It becomes possible. That is, the gap between the belt surface 18s of the handrail belt 18 and the cleaning unit 26 (cleaning unit main body 26M) is enlarged, and the pressure on the inserted foreign matter Fm is eliminated.

As described above, according to the cleaning unit mounting device 10 of the first embodiment, even if the foreign matter Fm is inserted at a position close to the rotation shaft 40, the attraction force of the first attraction member 28A composed of a magnet or the like is reduced. The foreign matter Fm can be forcibly released by the release pin 32 that operates when the foreign matter Fm is inserted. Therefore, the cleaning unit mounting device 10 has a simple structure and can easily avoid the risk of fingers being caught.

FIG. 5A is an exemplary and schematic side view showing the structure for fixing the cleaning unit mounting device 10 of the first embodiment to the balustrade panel 20. FIG. 5B is an exemplary and schematic top view showing the structure for fixing the cleaning unit mounting device 10 to the balustrade panel 20. FIG.

As described above, the support arms 24A and 24B are configured to bend the balustrade curved portion 20a (belt curved portion 18a) of the balustrade panel 20 (support) that supports the handrail belt 18 at the boarding/alighting position 14 (boarding/alighting portion) of the escalator 12. It is mounted at a position below the center S (below the horizontal line r in FIG. 1) or at a substantially horizontal position. By arranging the support arm 24 (cleaning unit mounting device 10) at a position lower than the position substantially parallel to the boarding/alighting position 14, the weight of the cleaning unit 26 allows the cleaning unit 26 to move smoothly to the second posture. can be done. Further, by arranging the cleaning unit 26 in a substantially horizontal position, the cleaning unit 26 can be moved to the second posture without any extra load.

The support arms 24A and 24B can be fixed to the balustrade panel 20 by using, for example, bolts 24b and nuts 24c as fixing members. In this case, it is necessary to make a hole in the balustrade panel 20 for inserting the bolt 24b. Also, as shown in FIG. 5B, the thickness of the balustrade panel 20 is often thinner than the width of the handrail belt 18 . Therefore, the support arms 24A and 24B are provided with recesses 24d for fixing. The concave portion 24d has a bottomed cylindrical shape, for example, and the cylindrical bottom portion serving as a fixing portion for the support arms 24A and 24B is brought close to the surface of the balustrade panel 20, and is firmly fixed using a bolt 24b and a nut 24c. By firmly fixing the support arms 24A and 24B to the balustrade panel 20, even if a foreign object Fm is inserted between the belt surface 18s and the cleaning unit 26, the cleaning unit mounting device 10 will not come off the balustrade panel 20. problems can be avoided. Even when the support arms 24A and 24B are firmly fixed to the balustrade panel 20, when the foreign matter Fm is inserted, the first adsorption member 28A is separated from the support arm 24A side as described above. Excessive pressure can be avoided.

The support arms 24A and 24B can be fixed to the balustrade panel 20 by using bolts 24b and nuts 24c, as well as adhesives, suction cups, magnets, etc., and the same effect can be obtained. When fixing the support arms 24A and 24B to the balustrade panel 20, if suction cups, magnets, or the like are used, a lock mechanism may be provided to maintain the attached state. In this way, by using an easily attachable/detachable structure, the cleaning unit attachment device 10 can be easily attached/detached, and the attachment position can be easily moved. Also, the cleaning unit mounting device 10 can be easily installed on the existing escalator 12, and the introduction of the cleaning unit mounting device 10 is facilitated.

FIG. 6A is an exemplary and schematic top view showing a first state (a state in which the release pin 32 remains protruding) of the cleaning unit mounting device 10 of the first embodiment during the return operation after the completion of the safety operation. . FIG. 6B is an exemplary and schematic top view showing a second state (a state in which the release pin 32 has shifted to the non-protruding state) during the return operation after the completion of the complete operation of the cleaning unit mounting device 10. As shown in FIG.

In FIG. 6A, the cleaning unit 26 is rotated in the direction of the reverse arrow C in order to resume the cleaning and disinfection treatment by the cleaning unit mounting device 10 from the state of FIG. This is a state in which one adsorption member 28A is brought close to the support arm 24A. In this case, the first sliding member 30 remains slid (biased) in the arrow A2 direction. Therefore, the engaging pin 38 of the second sliding member 36 abuts against the outside of the engaging groove 30b of the first sliding member 30 and remains in a state of being unable to engage. That is, the second sliding member 36 remains moving (sliding) in the arrow B2 direction, and the third sliding member 42 also remains relatively moved in the arrow A2 direction. That is, even after the foreign matter Fm has been removed, the tip 32a of the release pin 32 still protrudes from the first adsorption member 28A, preventing the first adsorption member 28A from being adsorbed to the support arm 24A. . Therefore, the cleaning unit main body 26M also remains in a state of being inclined with respect to the belt surface 18s, and is in a state in which normal sterilization cleaning processing cannot be performed.

Therefore, the administrator of the cleaning unit mounting device 10 or the escalator 12 confirms that the foreign matter (for example, the finger of the user of the escalator 12) inserted between the belt surface 18s and the cleaning unit 26 has been removed. After that, the cleaning unit mounting device 10 is restored. In this case, the administrator pushes the release pin 32 protruding from the insertion hole 28h of the first adsorption member 28A in the direction of the arrow A1 against the biasing force of the biasing member 34, as shown in FIG. 6B. In this case, in order to push the release pin 32 into the insertion hole 28h, a restoration tool having a convex portion narrower than the size of the insertion hole 28h may be used. In this case, it is possible to prevent a third party from returning the cleaning unit mounting device 10 without permission.

By pushing the release pin 32 into the insertion hole 28h, the first sliding member 30 moves in the arrow A1 direction. At this time, since the foreign matter Fm has been removed, the third sliding member 42 tries to move in the arrow A1 direction due to the biasing force of the biasing member 46 . As a result, the guide pin 36a of the second slide member 36, which is engaged with the guide portion 42b of the third slide member 42, moves toward the support member. That is, the second sliding member 36 moves in the direction of the arrow B1, the engagement pin 38 engages with the engagement groove 30b as shown in FIG. 6B, and returns to the state shown in FIG. 4A. As a result, the first adsorption member 28A can be adsorbed to the support arm 24A, the cleaning unit main body 26M returns to the state facing (directly facing) the belt surface 18s, and the sterilization cleaning process can be performed normally. return.

In this way, the safety mechanism of the cleaning unit mounting device 10 can be easily restored after the safety operation is finished, and can contribute to improving usability of the cleaning unit mounting device 10 .

FIG. 6C shows the behavior of the cleaning unit mounting device 10 when the foreign matter Fm is inserted at a position far from the rotation shaft 40, and the third state (release pin 32 remains non-protruding) is an exemplary schematic top view.

In the cleaning unit mounting device 10, when the foreign matter Fm is inserted at a position far from the rotation shaft 40 (when the foreign matter is inserted near the first adsorption member 28A), as will be described later, the foreign matter Fm The first adsorption member 28A can be easily separated from the support arm 24A with a smaller force than when it is inserted at a position close to 40. At this time, relative movement (movement in the arrow A2 direction) of the support portion 44 and the third sliding member 42 with respect to the base member 26A is less likely to occur. That is, the second sliding member 36 is less likely to slide in the arrow B2 direction. As a result, as shown in FIG. 6C, the first adsorption member 28A is detached from the support arm 24A while the engagement pin 38 is not detached from the engagement groove 30b, and the cleaning unit 26 (cleaning unit main body 26M) is , are separated from the belt surface 18s and can be shifted to the second posture. That is, the gap between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M) is enlarged, and the pressure on the inserted foreign matter Fm is eliminated. Therefore, the cleaning unit attachment device 10 can be operated safely (to the second posture) without forcibly separating the first adsorption member 28A from the support arm 24A by the release pin 32 as described with reference to FIGS. 4A to 4D. migration) can be realized.

As described above, the cleaning unit 26 shifts to the second posture while the release pin 32 does not protrude from the insertion hole 28h of the first adsorption member 28A. Therefore, after the foreign matter Fm is removed, the first adsorption member 28A can be adsorbed to the support arm 24A by rotating the first adsorption member 28A so as to approach the support arm 24A. As a result, the cleaning unit main body 26M returns to a state in which it faces (directly faces) the belt surface 18s, and returns to a state in which the sterilization cleaning process can be performed normally.

If the foreign matter Fm is the finger of the user of the escalator 12, it is caught between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M), and the cleaning unit 26 shifts to the second posture. It is easy to perceive danger by its conspicuous movements. As a result, the finger or the like is removed from between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M). In such a case, once the cleaning unit 26 has moved to the second posture, even if it automatically returns to the first posture, no problem will occur. Therefore, an urging member such as a return spring may be provided at the rotary shaft 40 to urge the cleaning unit 26 toward the first posture. In this case, the biasing force of the return spring may be smaller than the attracting force of the first attracting member 28A, and may be sufficient to cause the cleaning unit 26 to start rotating in the direction of the first posture.

As described above, the cleaning unit mounting device 10 moves relative to the cleaning unit 26 with respect to the rotation shaft 40 (support arm 24B) by means of a sliding mechanism such as the third sliding member 42 or the like. As a result, the release pin 32 is used to forcibly separate the first adsorption member 28A from the support arm 24A. Another simplified structure is a structure in which the rotating shaft 40 and the cleaning unit 26 do not move relative to each other. good. In this case, although the pressing force applied to the foreign object Fm changes depending on the position where the foreign object Fm is inserted, it is possible to easily avoid the risk of fingers being caught.

For example, FIG. 7 shows a structure in which the cleaning unit 26 does not move relative to the rotating shaft 40 fixed to one of the support arms 24, and the first adsorption member 28A is attracted to the other support arm 24. FIG. 10 is a model showing a state in which the vehicle is in a state where the vehicle is in a state, and is a comparison diagram for explaining a safe operation function.

For example, when the separation distance between the rotation shaft 40 and the first adsorption member 28A is L, and the adsorption force of the first adsorption member 28A to the support arm 24A is F, the foreign matter Fma When the foreign object Fma is inserted at a distance of, for example, 1/5L from 40, the following relationship is established between the force Fa applied to the foreign object Fma.
Fa×1L/5=F×L
Fa = 5F
Therefore, by the time the first adsorption member 28A separates from the support arm 24A, a force five times the adsorption force of the first adsorption member 28A is applied to the foreign matter Fma.

On the other hand, for example, when the foreign object Fmb is inserted at a distance of, for example, 4/5L from the rotation shaft 40, the following relationship is established between the foreign object Fmb and the force Fb applied to the foreign object Fmb.
Fa×4L/5=F×L
Fa=5F/4=1.25F
Therefore, a force 1.25 times the adsorption force of the first adsorption member 28A is applied to the foreign matter Fmb before the first adsorption member 28A separates from the support arm 24A.
In this way, the insertion of the foreign matter Fma, Fmb can realize a safety mechanism that allows the first adsorption member 28A to be easily separated from the support arm 24A. Variation occurs in the force required to detach 28A.

On the other hand, as in the cleaning unit mounting device 10, the rotary shaft 40 and the cleaning unit 26 move relative to each other due to the insertion of the foreign matter Fm, and the release pin 32 forcibly separates from the first adsorption member 28A due to the relative movement. 8, the model comparison diagram is shown in FIG.

For example, when the separation distance between the rotating shaft 40 and the first attracting member 28A is the distance L, and the sliding force when the rotating shaft 40 and the cleaning unit 26 move relative to each other is Fx, the foreign matter Fma rotates. Consider the case where it is inserted at a distance of, for example, 1/5L from the axis 40 . The sliding force Fx is assumed to be equal to F, which is the attraction force of the first attraction member 28A to the support arm 24A. In this case, since the rotating shaft 40 and the cleaning unit 26 move relative to each other, the following relationship is established between the force Fa applied to the foreign matter Fma until the first attracting member 28A separates from the support arm 24A. It holds.
Fa×4L/5=Fx×L
Fa=5Fx/4=1.25Fx=1.25F
Therefore, a force 1.25 times the adsorption force of the first adsorption member 28A is applied to the foreign matter Fma by the time the first adsorption member 28A separates from the support arm 24A.

On the other hand, for example, when the foreign object Fmb is inserted at a distance of, for example, 4/5L from the rotation shaft 40, the following relationship is established between the foreign object Fmb and the force Fb applied to the foreign object Fmb.
Fa×4L/5=F×L
Fa=5F/4=1.25F
Therefore, a force 1.25 times the adsorption force of the first adsorption member 28A is applied to the foreign matter Fmb before the first adsorption member 28A separates from the support arm 24A.

Further, for example, when the foreign object Fmc is inserted at a distance of, for example, 1/2L from the rotation shaft 40, the following relationship is established between the foreign object Fmc and the force Fc applied to the foreign object Fmc.
Fc×1L/2=F×L
Fc = 2F
Therefore, by the time the first adsorption member 28A separates from the support arm 24A, a force twice the adsorption force of the first adsorption member 28A is applied to the foreign matter Fmc.

As described above, when the release pin 32 is used to forcibly separate the first adsorption member 28A from the support arm 24A using the slide mechanism, the first adsorption member 28A is more likely to move than when the configuration is not provided. Variation can be further reduced while avoiding an increase in the force required for detachment. In other words, the structure that separates the first adsorption member 28A from the support arm 24A by inserting the foreign object Fm makes it possible to easily avoid the risk of a finger or the like getting caught. It is possible to realize a safety mechanism that easily avoids pinching of fingers or the like at risk.

<Second embodiment>
9A to 9C are exemplary and schematic top views explaining the configuration of the cleaning unit mounting device 10A of the second embodiment. FIG. 9A is an exemplary and schematic top view showing the state of the cleaning unit mounting device 10A before the safety operation is started. FIG. 9B is an exemplary and schematic top view showing a state in which the safety operation of the cleaning unit mounting device 10A has functioned. FIG. 9C is an exemplary and schematic top view showing another state in which the safety operation of the cleaning unit mounting device 10A has functioned.

The cleaning unit 26 of the cleaning unit mounting device 10A includes a first adsorption member 28A and a second adsorption member 28B. That is, the first adsorption member 28A that can be adsorbed to one support arm 24A of the pair of support arms 24 and the second adsorption member 28B that can be adsorbed to the other support arm 24B are provided. Also, the cleaning unit 26 has a first rotation shaft 40A that shifts the cleaning unit 26 to the second posture when the second adsorption member 28B is not adsorbed to the support arm 24B. Similarly, the cleaning unit 26 has a second pivot shaft 40B that shifts the cleaning unit 26 to the second posture when the first adsorption member 28A is no longer adsorbed to the support arm 24A.

That is, as shown in FIG. 9A, the cleaning unit mounting device 10A is in a state in which the first suction member 28A is suctioned to the support arm 24A and the second suction member 28B is suctioned to the support arm 24B. Second, the cleaning unit 26 faces the belt surface 18s of the handrail belt 18 to achieve the first posture for cleaning and disinfecting.

Here, as shown in FIG. 9B, when a foreign object Fma is inserted at a position close to the second adsorption member 28B, the second adsorption member 28B is separated from the support arm 24B by the insertion of the foreign object Fma, and cleaning is performed. The unit 26 rotates about the first rotation shaft 40A while the first adsorption member 28A is adsorbed to the support arm 24A, and separates the cleaning unit 26 from the belt surface 18s of the handrail belt 18. Realize two postures. That is, the gap between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M) is enlarged, the pressure on the inserted foreign matter Fma is eliminated, and the risk of fingers being caught can be easily avoided.

Similarly, as shown in FIG. 9C, in the cleaning unit mounting device 10A, when a foreign object Fmb is inserted at a position close to the first adsorption member 28A, the insertion of the foreign object Fmb causes the first adsorption member 28A to be supported. After being separated from the arm 24A, the cleaning unit 26 rotates around the second rotation shaft 40B while the second adsorption member 28B is adsorbed to the support arm 24B. A second position away from the belt surface 18s is achieved. That is, also in this case, the gap between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M) is enlarged, the pressure on the inserted foreign matter Fmb is eliminated, and the risk of fingers being caught can be easily avoided. can be done.

In the case of the cleaning unit mounting device 10A, the first adsorption member 28A may detach from the support arm 24A and the second adsorption member 28B may detach from the support arm 24B. In that case, in order to prevent the cleaning unit 26 from falling, it is desirable to connect the cleaning unit 26 to a portion of the support arm 24 or a portion of the balustrade panel 20 using a connecting member such as a wire. .

As described above, according to the cleaning unit mounting device 10A of the second embodiment, even if the foreign matter Fm is inserted at any position between the belt surface 18s and the cleaning unit 26, the first first magnet made of a magnet or the like is inserted. The adsorption member 28A or the second adsorption member 28B can be detached from the support arm 24. As shown in FIG. Therefore, the cleaning unit mounting device 10A has a simple structure and can easily avoid the risk of fingers being caught.

<Third Embodiment>
FIG. 10 is an exemplary and schematic top view showing the detailed structure of the cleaning unit mounting device 10B of the third embodiment. 11A is a cross-sectional view along the line KK of FIG. 10, which is an exemplary and schematic cross-sectional view showing the link structure of the cleaning unit mounting device 10B, and FIG. 11B is a cross-sectional view along the line KK of FIG. and is an exemplary and schematic cross-sectional view showing the operating state of the link structure of the cleaning unit mounting device 10B.

The cleaning unit mounting device 10B of the third embodiment has a structure that includes a link mechanism 48 and slides the first sliding member 30 of the cleaning unit mounting device 10 of the first embodiment. That is, using the link mechanism 48, the wire 50a that slides while being guided by the wire case 50 operates the engagement pin 52 that allows the first sliding member 30 to slide. The configuration of the first sliding member 30 having the flange portion 30a and the engaging groove 30b, the release pin 32 connected to the first sliding member 30, and the projecting action of the release pin 32 allow the first attracting member to move. The structure for forcibly separating 28A from support arm 24A is the same as that of the above-described first embodiment, and detailed description thereof will be omitted.

In the case of the cleaning unit mounting device 10B of the third embodiment, the rotation shaft 40 (first rotation shaft) is provided on the support arm 24B of the pair of support arms 24 that is not attracted by the first adsorption member 28A. pivotally supports the support member 44a of the cleaning unit 26. As shown in FIG. In other words, unlike the cleaning unit mounting device 10 of the first embodiment, the cleaning unit 26 can be moved between the first posture and the second posture without allowing relative movement between the rotating shaft 40 and the cleaning unit 26 . swirl.

A detailed structure of the cleaning unit mounting device 10B will be described with reference to FIGS. 10, 11A, and 11B.

The cleaning unit 26 includes a first adsorption member 28A that can be adsorbed to one support arm 24A of the pair of support arms 24. As shown in FIG. The cleaning unit 26 also includes a first sliding member 30 having a release pin 32 (protruding portion) biased to protrude in a direction in which the first attracting member 28A is moved away from the supporting arm 24A sucking the first attracting member 28A. Prepare. This configuration is the same as the cleaning unit mounting device 10 of the first embodiment.

The cleaning unit 26 also includes an engagement pin 52 (engagement member) and a link mechanism 48 . The engagement pin 52 is slidable in a direction substantially orthogonal to the first sliding member 30, and has an engagement position where the release pin 32 engages at a first position in which the release pin 32 is in a non-protruding posture, and a release pin. 32 is a member that can move between a disengaged position and a disengaged position that allows it to slide to a second position in which it is in a protruded posture, and is operated by a link mechanism 48 . The engagement pin 52 is a rod-shaped member such as a cylinder or prism, and is slidably supported in the directions of arrows B1 and B2 by a support member 26t fixed on the plane portion of the base member 26A. A flange portion 52a is formed in an intermediate region of the engaging pin 52. As shown in FIG. A compression spring, for example, is arranged as the biasing member 54 between the support member 26t and the flange portion 52a. Therefore, the engaging pin 52 is biased in the direction of the arrow B1 by the biasing member 54 so that the engaging pin 52 engages with the engaging groove 30b of the first sliding member 30. As shown in FIG. In this state, the release pin 32 of the first sliding member 30 is maintained in a non-projecting state. Further, when the engagement pin 52 moves in the direction of arrow B2 against the biasing force of the biasing member 54 due to the operation of the link mechanism 48, the first sliding member 30 moves in the direction of arrow A2 due to the biasing force of the biasing member 34. It slides and the release pin 32 shifts to a projecting state. That is, the first adsorption member 28A is forcibly separated from the support arm 24A.

The cleaning unit 26 includes a rotation shaft 40 (first rotation shaft) that shifts the cleaning unit 26 to the second posture when the first adsorption member 28A is not adsorbed to the support arm 24A.

The link mechanism 48 extends in the width direction of the handrail belt 18 in the gap M formed between the belt surface 18s of the handrail belt 18 and the cleaning unit 26, and is operated by a foreign object that enters the gap M, causing the engagement pin 52 to move. Move to the disengaged position. As shown in FIG. 11A, the link mechanism 48 is composed of multiple links. The link mechanism 48 includes a first operating lever 48 a , a second operating lever 48 b , a first link bar 56 , a second link bar 58 and a third link bar 60 .

As shown in FIG. 10, the first operating lever 48a is a member having a wide portion 48t extending in the width direction of the handrail belt 18 in the gap M formed between the belt surface 18s and the cleaning unit 26. It is rotatable around a fixed shaft 48pa supported by the support member 26t of the base member 26A of the cleaning unit 26 or the like. The first operating lever 48a is rotatably connected to one end of the first link bar 56 at the end opposite to the wide portion 48t exposed in the gap M. As shown in FIG. The other end of the first link bar 56 is rotatably connected to one end of a third link bar 60 which is rotatable around a fixed shaft 60p supported by the support member 26t of the base member 26A. It is

On the other hand, the second operating lever 48b also has a wide portion 48t extending in the width direction of the handrail belt 18 in the gap M formed between the belt surface 18s and the cleaning unit 26, as shown in FIG. It is rotatable around a fixed shaft 48pb supported by the support member 26t of the base member 26A of the cleaning unit 26 or the like. The second operating lever 48b is rotatably connected to one end of the second link bar 58 at the end opposite to the wide portion 48t exposed in the gap M. As shown in FIG. The other end side of the second link bar 58 is rotatably connected to the other end side of the third link bar 60 .

A wire 50a connected to the engagement pin 52 is fixed to the end of the third link bar 60 to which the second link bar 58 is connected, for example. The wire 50a is slidably housed inside a wire case 50 supported by the support member 26t and the like.

The linking operation of the cleaning unit mounting device 10B having the link mechanism 48 configured in this way will be described with reference to FIG. 11B.

For example, consider a case where a foreign object Fm (for example, a user's finger) is inserted into the gap M between the handrail belt 18 and the cleaning unit 26 from below the cleaning unit mounting device 10B (cleaning unit 26). In this case, when the foreign matter Fm is inserted into the gap M between the handrail belt 18 and the cleaning unit 26, the foreign matter Fm contacts the wide portion 48t of the second operating lever 48b, and the second operating lever 48b is fixed. It rotates in the arrow N2 direction with the shaft 48pb as the center of rotation. As a result, the second link bar 58 is pulled down. A third link bar 60 is connected to the other end of the second link bar 58 . As the second link bar 58 is pulled down, the third link bar 60 rotates about the fixed shaft 60p in the arrow N2 direction.

As described above, since the wire 50a is fixed to the end of the third link bar 60, the wire 50a is pulled in the arrow J direction by the rotation of the third link bar 60 in the arrow N2 direction. As shown in FIG. 10, an engaging pin 52 is fixed to the other end of the wire 50a while being biased in the direction of arrow B1 by a biasing member 54. As shown in FIG. Therefore, when the wire 50a is pulled in the direction of the arrow J, the engaging pin 52 is disengaged from the engaging groove 30b of the first sliding member 30 against the biasing force of the biasing member 54, and biased by the biasing member 34. The first sliding member 30 in the closed state slides in the arrow A2 direction. Then, the release pin 32 protrudes from the insertion hole 28h of the first adsorption member 28A to separate the first adsorption member 28A, that is, the cleaning unit 26, from the support arm 24A. As a result, the gap between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M) is enlarged, the pressure on the inserted foreign matter Fm is eliminated, and the risk of fingers being caught can be easily avoided.

Similarly, for example, a foreign object Fm (for example, a user's finger or the like) is inserted into the gap M between the handrail belt 18 and the cleaning unit 26 from above the cleaning unit mounting device 10B (cleaning unit 26). think. In this case, when a foreign object Fm is inserted into the gap M between the handrail belt 18 and the cleaning unit 26, the foreign object Fm contacts the wide portion 48t of the first operating lever 48a, and the first operating lever 48a moves toward the fixed shaft. It rotates in the direction of arrow N1 with 48pa as the center of rotation. As a result, the first link bar 56 is pulled up. A third link bar 60 is connected to the other end of the first link bar 56 . By pulling up the second link bar 58, the third link bar 60 rotates about the fixed shaft 60p in the arrow N2 direction.

Since the wire 50a is fixed to the end of the third link bar 60, the wire 50a is pulled in the arrow J direction by the rotation of the third link bar 60 in the arrow N2 direction. As a result, the wire 50a is pulled in the direction of arrow J in the same way as when the second operating lever 48b is rotated, causing the engaging pin 52 to resist the biasing force of the biasing member 54 and the first sliding member. The first sliding member 30 disengaged from the engagement groove 30b of 30 and urged by the urging member 34 slides in the arrow A2 direction. Then, the release pin 32 protrudes from the insertion hole 28h of the first adsorption member 28A to separate the first adsorption member 28A, that is, the cleaning unit 26, from the support arm 24A. As a result, the gap M between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M) is enlarged, the pressure on the inserted foreign matter Fm is eliminated, and the risk of fingers being caught can be easily avoided. .

As described above, according to the cleaning unit mounting device 10B of the third embodiment, even if the foreign matter Fm is inserted in any position of the gap M between the belt surface 18s and the cleaning unit 26 (cleaning unit main body 26M), The first operating lever 48a or the second operating lever 48b operates, and the release pin 32 forcibly releases the attractive force of the first attractive member 28A composed of a magnet or the like. Therefore, with a simple structure, it is possible to easily avoid the risk of fingers being caught.

When the cleaning unit mounting device 10B is returned to the first posture from the second posture, if the foreign matter Fm is removed, the link mechanism 48 automatically returns. For example, the first sliding member 30 is returned to the initial state by pushing the release pin 32 projecting from the first adsorption member 28A in the direction of the arrow A1 against the biasing force of the biasing member 34 . In this state, the first adsorption member 28A can be adsorbed to the support arm 24A, the cleaning unit 26 returns to the first posture, and cleaning and sterilization processing becomes possible. Further, by moving the first sliding member 30 in the direction of the arrow A1, the engaging pin 52 can be engaged with the engaging groove 30b. Since the engaging pin 52 is biased by the biasing member 54, the wire 50a moves in the direction of the reverse arrow J in FIG. 11B, and the third link bar 60 rotates in the direction of the reverse arrow N2. As a result, the first operating lever 48a rotates in the direction of the reverse arrow N1, the second operating lever 48b rotates in the direction of the reverse arrow N2, and each wide portion 48t returns to the initial position. That is, the link mechanism 48 returns to its initial state.

<Modification>
As described above, the passenger conveyor to which the cleaning unit mounting devices 10, 10A, and 10B of each embodiment are applied is, for example, an inclined moving path 16a connecting the upper floor and the lower floor. , and the steps 16 move in a stepped state. The cleaning unit mounting devices 10, 10A, 10B can be applied to other types of passenger conveyors to obtain similar effects. For example, the cleaning unit mounting devices 10, 10A, and 10B may be applied to an escalator in which the step 16 transitions once to a horizontal state on the way of the moving path 16a and then transitions to a stepped state again. Also in this case, the same effects as those of the above-described embodiments 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 devices 10, 10A and 10B may be applied to a so-called "moving walkway". Also in this case, the same effects as those of the above-described embodiments can be obtained.

Further, in the above-described embodiment, the cleaning unit main body 26M 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 main body 26M includes a device for wiping sprayed liquid or the like and a cooling device for returning the heated handrail belt 18 to room temperature so that the user does not feel uncomfortable when touching the handrail belt 18 by sterilization treatment. etc. may be provided.

Although several embodiments of the invention have been described above, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, as well as the scope of the invention described in the claims and equivalents thereof.
