  However, according to the handrail belt guide device described in Patent Document 1, the roller of the handrail belt guide device may come into strong contact with the handrail belt. , May cause knocking. Further, if the handrail belt guide device is removed in order to solve such a problem, there is a high possibility that the track of the handrail belt cannot be secured, and a situation in which the guide function is not performed occurs.

  The present invention has been made in order to solve such a conventional problem, and the object of the present invention is to suppress the frequency of occurrence of refraction and knocking of the handrail belt and to prevent the guide function from being performed. It is providing the handrail belt guide apparatus and passenger conveyor of a passenger conveyor which can suppress this.

  The handrail belt guide device for a passenger conveyor of the present invention guides the handrail belt while the handrail belt that circulates between the entrance and the exit moves from the exit side to the entrance side. It is. The handrail belt guide device for the passenger conveyor includes a restriction roller for restricting displacement in the width direction of the handrail belt, and the handrail belt is displaced in a direction substantially orthogonal to the width direction and the moving direction of the handrail belt.

As described above, since the regulating roller is displaced following the handrail belt, the regulation roller does not come into strong contact with the handrail belt when the handrail belt is displaced, and the frequency of occurrence of refraction and knocking of the handrail belt is suppressed. be able to. Furthermore, since the regulating roller is displaced in the same manner as the handrail belt, the frequency at which the regulating roller is detached from the handrail belt is reduced, and the situation where the guiding function is not performed can be suppressed.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings. In the following, an escalator is described as an example of a passenger conveyor. However, the passenger conveyor is not limited to an escalator, and may be any other conveyor device that transports a stationary passenger such as a moving sidewalk.

(First embodiment)
FIG. 1 is a schematic side view of an escalator according to a first embodiment of the present invention. In FIG. 1, for the sake of illustration, a part of the internal configuration of the passenger conveyor that is not visible from the outside of the passenger conveyor is illustrated in a state that is visible from the outside. The escalator shown in FIG. 1 will be described by taking as an example a case where the lower floor side is the entrance and the upper floor side is the exit.

  As shown in FIG. 1, the passenger conveyor 1 according to the first embodiment includes a truss structure 10, a number of steps 20, a pair of balustrades 30, a handrail belt 40, and a pair of skirt portions 50. The drive device 60, the step drive unit 70, the handrail belt drive unit 80, and a plurality of handrail belt guide devices 90 are included.

  The truss structure 10 is a framework having a structure in which a triangular unit is a basic unit, which is disposed between an upper floor and a lower floor. A number of steps 20 are connected by an endless step chain and circulate through the truss structure 10 to carry passengers in a stationary state. The pair of balustrades 30 are provided at both sides of the step 20 in the width direction, and have a role of preventing passengers from falling off the step 20 in the width direction. The handrail belt 40 is attached to each peripheral edge of the pair of balustrades 30 and circulates between the entrance and the exit. The handrail belt 40 moves in synchronization with the step 20, and has a substantially concave cross section (see FIG. 3). The pair of skirt portions 50 covers the lower positions of the pair of balustrades 30 and is provided between the lower floor entrance and the lower floor entrance.

  The driving device 60 generates power for circulating and moving the numerous steps 20 and the handrail belt 40. The drive device 60 includes a drive chain 61 and is configured to transmit the generated power to the step drive unit 70. The step drive unit 70 has step drive wheels 71 connected to the drive chain 61. The step drive wheel 71 is a gear that rotates about a central axis, and is configured to mesh with a step chain (not shown) that is endlessly connected to a number of steps 20. With this configuration, the power of the driving device 60 is transmitted to the step drive wheel 71 via the drive chain 61, and is transmitted from the step drive wheel 71 to a number of steps 20 via the step chain. Further, the step drive unit 70 has a first sprocket 72. The first sprocket 72 is a gear having the same central axis as the step drive wheel 71 and having an outer diameter smaller than that of the step drive wheel 71. The first sprocket 72 rotates in synchronization with the step drive wheel 71 when the power of the drive device 60 is transmitted to the step drive wheel 71 via the drive chain 61.

  The handrail belt drive unit 80 includes a second sprocket 81, a handrail chain 82, a handrail drive wheel 83, and a guide roller 84. The second sprocket 81 is a gear that rotates around a central axis. The handrail chain 82 meshes with both the gears of the first sprocket 72 and the second sprocket 81. With this configuration, when the step drive wheel 71 rotates, the first sprocket 72 rotates, and this rotational force is transmitted to the second sprocket 82 via the handrail chain 82, so that the second sprocket 82 rotates. The handrail drive wheel 83 is a rotating body having the same central axis as the second sprocket 82 and having an outer diameter larger than that of the second sprocket 82. The handrail drive wheel 83 rotates in synchronization with the rotation of the second sprocket 82. Further, the handrail drive wheel 83 is in contact with the handrail belt 40, and gives a force for the handrail belt 40 to move from the exit to the entrance through its own rotation. The guide roller 84 is a roller on which the handrail belt 40 is placed, and is configured to rotate according to the movement of the handrail belt 40 by the force of the handrail drive wheel 83.

  The handrail belt guide device 90 guides the handrail belt 40 while the handrail belt 40 that circulates between the entrance and the exit moves from the exit side to the entrance side. The handrail belt guide device 90 is installed at a location where the handrail belt 40 passes from the exit side to the entrance side, for example, at a plurality of locations in the truss structure 10.

  FIG. 2 is a side view showing details of the handrail belt guide device 90 shown in FIG. Since each handrail belt guide device 90 is configured or approximate, only one handrail belt guide device 90 will be described in FIG. As shown in FIG. 2, the handrail belt guide device 90 includes a support 91, a support arm (displacement member) 92, a shaft 93, a restriction roller 94, a limiter 95, and an initial position determination member 96. Yes.

  The support 91 is a plate-like member fixed in the truss structure body 10. The support arm 92 is a plate material having a substantially L-shaped cross section. The shaft 93 is a member serving as a rotation shaft for rotatably attaching the support arm 92 to the support 91. The restriction roller 94 is a roller attached to the tip end side of the support arm 93 (in the example shown in FIG. 2, the moving direction side of the handrail belt 40).

  3 is a cross-sectional view taken along line AA shown in FIG. As shown in FIG. 3, the regulating roller 94 has a long shaft 94 a extending in a substantially orthogonal direction orthogonal to the width direction and the moving direction of the handrail belt 40. One end of the long shaft 94a is fixed to the support arm 92 with a nut through packing or the like. The regulation roller 94 has a roller portion 94b. The roller portion 94b is attached to the other end of the long shaft 94a, and is configured to rotate in either the left or right rotation direction with the long shaft 94 as a central axis. The roller portion 94b is attached so as not to contact the jaw portions 40a and 40b of the handrail belt 40 when the handrail belt 40 is not vibrating. Due to such a configuration, when the vibration or the like occurs in the width direction of the handrail belt 40, the restriction roller 94 comes into contact with any one of the jaw portions 40a and 40b and restricts the displacement in the width direction. It becomes. Further, when the roller portion 94b comes into contact with the jaw portions 40a and 40b, the roller portion 94b rotates around the long shaft 94a. Furthermore, the regulation roller 94 is located above the handrail belt 40 (upper side in the state where the passenger conveyor 1 is installed), and does not contact the inner lower surface (the inner lower surface of the recess) 40c of the handrail belt 40. It has become.

  Although not shown in FIGS. 2 and 3, a guide roller 84 is provided below the handrail belt 40, and the handrail belt 40 travels on the guide roller 84.

  FIG. 4 is a cross-sectional view showing an example of another handrail belt guide device. For example, as shown in FIG. 4, when the restriction roller 100 whose position is fixed guides the handrail belt 101, if the handrail belt 101 is lifted by vibration or the like, the handrail belt 101 strongly presses against the restriction roller 100. Will be. For this reason, the handrail belt 101 is bent or knocked. However, in the handrail belt guiding apparatus 90 according to the first embodiment, since the support arm 92 displaces the restriction roller 94 in the same direction as the displacement of the handrail belt 40, the handrail belt 40 is strongly against the restriction roller 94. The frequency of occurrence of bending and knocking of the handrail belt 40 is reduced without being pressed.

  Refer to FIG. 2 again. The limiter 95 prevents the regulating roller 94 from being displaced beyond a specified amount in the direction from the handrail belt 40 toward the regulating roller 94. For example, when the handrail belt 40 is vigorously displaced toward the regulation roller 94 due to vibration or the like, the regulation roller 94 is greatly repelled. When the restriction roller 94 is rebounded in this way, the restriction roller 94 is temporarily removed from the concave portion of the handrail belt 40. During this period, the regulating roller 94 does not perform the guide function of the handrail belt 40. However, since the handrail belt guide device 90 includes the limiter 95, even if the restriction roller 94 is largely repelled, the restriction roller 94 is not displaced by the limiter 95, and it is relatively quickly positioned at an appropriate position as compared with the case without the limiter 95. It will be possible to return.

  The initial position determination member 96 determines the initial position of the restriction roller 94. That is, the initial position determining member 96 holds the restriction roller 94 at the initial position when the handrail belt 40 moves to the restriction roller 94 side and does not displace the restriction roller 94. Here, for example, as shown in FIG. 3, the initial position means that the lower surface of the regulating roller 94 is not in contact with the concave lower surface 40 c of the handrail belt 40, and the roller portion 94 b is the jaw portions 40 a and 40 b of the handrail belt 40. A position that is the same position in the orthogonal direction. By holding the restriction roller 94 at such an initial position, the restriction roller 94 can be prevented from always contacting the handrail belt 40.

  Next, the operation of the handrail belt guide device 90 according to the first embodiment will be described. First, referring to FIG. For example, it is assumed that vibration is applied to the handrail belt 40 and the handrail belt 40 is displaced in the width direction. In this case, the regulating roller 94 guides the handrail belt 40 in a state where the roller portion 94b restricts the displacement of the handrail belt 40 in the width direction and the friction of the roller portion 94b is small.

  FIG. 5 is a side view showing the operation of the handrail belt guiding device 90 according to the first embodiment. As shown in FIG. 5, it is assumed that vibration is applied to the handrail belt 40 and the handrail belt 40 is lifted. In this case, the handrail belt 40 contacts the support arm 92, and the support arm 92 rotates around the shaft 93. As a result, the regulation roller 94 is displaced following the handrail belt 40. For this reason, when the handrail belt 40 is displaced, the restriction roller 94 does not come into strong contact with the handrail belt 40, and the frequency of occurrence of refraction and knocking of the handrail belt 40 is suppressed.

  FIG. 6 is a second side view showing the operation of the handrail belt guiding device 90 according to the first embodiment. As shown in FIG. 6, it is assumed that vibration is applied to the handrail belt 40 and the handrail belt 40 is lifted vigorously. In this case, the handrail belt 40 strikes the support arm 92 vigorously, and the handrail belt 40 repels the regulating roller 94 greatly. However, when the regulating roller 94 is displaced upward by a specified amount, the rear end side (opposite the front end side) of the support arm 92 contacts the limiter 95. As a result, the restriction roller 94 is displaced by a predetermined amount at the maximum, and returns to an appropriate position relatively quickly.

  As described above, according to the passenger conveyor 1 and its handrail belt guiding device 90 according to the first embodiment, the support arm 92 that displaces the regulating roller 94 in the same direction as the displacement of the handrail belt 40 is provided. Therefore, when the handrail belt 40 is displaced in a substantially orthogonal direction due to vibration or the like, the regulating roller 94 is displaced so as to follow this displacement. In this way, since the regulating roller 94 is displaced following the handrail belt 40, the regulation roller 94 does not come into strong contact with the handrail belt 40 when the handrail belt 40 is displaced, and the handrail belt 40 is bent or knocked. The frequency of occurrence can be suppressed. Furthermore, since the restriction roller 94 is displaced in the same manner as the handrail belt 40, the frequency at which the restriction roller 94 is detached from the handrail belt 40 is reduced, and the situation where the guide function is not performed can be suppressed.

  In addition, a limiter 95 is provided to prevent the restriction roller 94 from being displaced beyond a specified amount in the direction from the handrail belt 40 toward the restriction roller 94. Here, when the handrail belt 40 is vigorously displaced toward the regulating roller 94, the regulating roller 94 is greatly repelled. However, since the handrail belt guide device 90 includes the limiter 95, even if the handrail belt guide device 90 is largely repelled, the regulating roller 94 is not displaced by the limiter 95 and is positioned relatively quickly at an appropriate position as compared with the case without the limiter 95. It will return. Therefore, it is possible to further suppress the situation where the guidance function is not fulfilled.

  Further, the initial position of the regulating roller 94 is determined, and when the handrail belt 40 moves toward the regulating roller 94 and does not displace the regulating roller 94, an initial position determining member 96 that holds the regulating roller 94 at the initial position is provided. Prepare. For this reason, when the handrail belt 40 circulates and moves in a suitable state without vibrations, the positional relationship between the regulating roller 94 and the handrail belt 40 can be maintained in a predetermined state. Accordingly, it is possible to avoid a state in which the handrail belt 40 is apt to be bent or knocked easily, such as the regulation roller 94 is always in contact with the handrail belt 40, and the handrail belt 40 is bent or knocked. The frequency can be further suppressed.

(Second Embodiment)
Next, the passenger conveyor 1 and its handrail belt guiding device 90 according to the second embodiment will be described. The handrail belt guiding device 90 according to the second embodiment is the same as that of the first embodiment, but a part of the configuration is different. Hereinafter, differences from the first embodiment will be described.

  FIG. 7 is a side view showing details of the handrail belt guiding device 90 according to the second embodiment. As shown in FIG. 7, the handrail belt guiding device 90 includes a moving direction defining roller 97 in addition to the one in the first embodiment. Similar to the guide roller 84, the movement direction defining roller 97 rotates in accordance with the movement of the handrail belt.

  8 is a cross-sectional view taken along line BB shown in FIG. As shown in FIG. 8, the moving direction defining roller 97 includes a shaft member 97a and a roller portion 97b. One end of the shaft member 97a is integrally attached to the support arm 92 by bonding or the like. The roller portion 97b is attached to the other end of the shaft member 97a and is configured to rotate about the shaft member 97a as a central axis. The roller portion 97b is in contact with the concave lower surface 40c of the handrail belt 40 at the initial position. Thereby, when the handrail belt 40 moves, the moving direction defining roller 97 rotates along with this. With this configuration, the direction of movement of the handrail belt 40 can be easily maintained in a normal state, and the handrail belt can be guided more suitably.

  Further, since the movement direction defining roller 97 is attached to the support arm 92, when the handrail belt 40 is displaced in a substantially orthogonal direction, the movement direction defining roller 97 is displaced in the same direction as the movement of the handrail belt 40. Thereby, similarly to the regulation roller 94, the movement direction defining roller 97 can suppress the frequency of refraction and knocking of the handrail belt 40, and can also suppress the situation where the guide function is not performed. It can be configured.

  As described above, according to the passenger conveyor 1 and its handrail belt guiding device 90 according to the second embodiment, the restriction roller 94 is moved when the handrail belt 40 is displaced, as in the first embodiment. The frequency of occurrence of refraction and knocking of the handrail belt 40 can be suppressed without strongly contacting the handrail belt 40. Furthermore, the frequency at which the regulating roller 94 is detached from the handrail belt 40 is reduced, and the situation where the guiding function is not performed can be suppressed. In addition, since the limiter 95 is provided, it is possible to return to an appropriate position relatively quickly as compared with the case where the limiter 95 is not provided, and it is possible to further suppress a situation where the guide function is not performed. Further, it is possible to avoid a state in which refraction or knocking of the handrail belt 40 easily occurs, such as the regulation roller 94 always contacting the handrail belt 40, and the frequency of occurrence of refraction or knocking of the handrail belt 40. Can be further suppressed.

  Furthermore, according to the second embodiment, since the handrail belt guide device 90 includes the movement direction defining roller 97, the movement direction of the handrail belt 40 can be easily maintained in a regular state, and the handrail belt is more preferably used. 40 can be guided.

  Further, since the support arm 92 displaces the movement direction defining roller 97 in the same direction as the movement of the handrail belt 40, when the handrail belt 40 is displaced in a substantially orthogonal direction due to vibration or the like, the movement direction defining roller 97 is moved by the handrail. The belt 40 is displaced so as to follow the displacement of the belt 40. In this way, since the movement direction defining roller 97 follows and displaces, the movement direction defining roller 97 does not come into strong contact with the handrail belt 40 according to the displacement of the handrail belt 40, and the handrail belt 40 is refracted or knocked. Can be suppressed. Furthermore, since the movement direction defining roller 97 is displaced in the same manner as the handrail belt 40, the frequency that the movement direction defining roller 97 is detached from the handrail belt 40 is reduced, and the situation where the guide function is not performed is further suppressed. can do.

(Third embodiment)
Next, a passenger conveyor 1 and its handrail belt guide device 90 according to a third embodiment will be described. The handrail belt guide device 90 according to the third embodiment is the same as that of the first embodiment, but a part of the configuration is different. Hereinafter, differences from the first embodiment will be described.

  FIG. 9 is a side view showing details of the handrail belt guiding device 90 according to the third embodiment. As shown in FIG. 9, the handrail belt guiding device 90 includes a spring member (first spring member) 98 in addition to that of the first embodiment. The spring member 98 is a spring having one end attached to the support 91 and the other end attached to the rear end side of the support arm 92. Further, the spring member 98 is in a slightly extended state from the free state, and a force is applied so that the rear end side of the support arm 92 is pulled toward the initial position determining member 96.

  With this configuration, when the handrail belt 40 moves to the regulation roller 94 side and the regulation roller 94 is displaced in the same direction as the handrail belt 40, the spring member 98 is moved relative to the regulation roller 94. A force for returning to the original position (initial position) is applied. For example, it is assumed that vibration is applied to the handrail belt 40 and the handrail belt 40 is lifted vigorously. In this case, the handrail belt 40 strikes the support arm 92 vigorously, and the handrail belt 40 repels the regulating roller 94 greatly. However, the spring member 98 extends at the same time that the regulating roller 94 is repelled greatly. As a result, a force to restore the spring member 98 is applied to the support arm 92 to shorten the distance at which the restriction roller 94 is repelled, and to return to the original position with respect to the repelled restriction roller 94 at an early stage. It will be.

  As described above, according to the passenger conveyor 1 and its handrail belt guide device 90 according to the third embodiment, the restriction roller 94 is provided when the handrail belt 40 is displaced, as in the first embodiment. The frequency of occurrence of refraction and knocking of the handrail belt 40 can be suppressed without strongly contacting the handrail belt 40. Furthermore, the frequency at which the regulating roller 94 is detached from the handrail belt 40 is reduced, and the situation where the guiding function is not performed can be suppressed. In addition, since the limiter 95 is provided, it is possible to return to an appropriate position relatively quickly as compared with the case where the limiter 95 is not provided, and it is possible to further suppress a situation where the guide function is not performed. Further, it is possible to avoid a state in which refraction or knocking of the handrail belt 40 easily occurs, such as the regulation roller 94 always contacting the handrail belt 40, and the frequency of occurrence of refraction or knocking of the handrail belt 40. Can be further suppressed.

  Furthermore, according to the third embodiment, when the handrail belt 40 moves to the regulation roller 94 side and the regulation roller 94 moves in the same direction as the handrail belt 40, the regulation roller 94 is also moved. The spring member 98 which provides the force which returns to the position is provided. For this reason, when the handrail belt 40 moves toward the regulating roller 94 and bounces the regulating roller 94, the regulating roller 94 can be returned to the original position at an early stage as compared with the case where the spring member 98 is not provided. it can. Thereby, it is possible to further suppress the frequency at which the regulating roller 94 does not perform the guiding function.

(Fourth embodiment)
Next, a passenger conveyor 1 and its handrail belt guide device 90 according to a fourth embodiment will be described. A handrail belt guiding device 90 according to the fourth embodiment is configured by combining the second embodiment and the third embodiment. Hereinafter, the handrail belt guiding device 90 according to the fourth embodiment will be described.

  FIG. 10 is a side view showing details of the handrail belt guiding device 90 according to the fourth embodiment. As shown in FIG. 10, the handrail belt guiding device 90 includes both the movement direction defining roller 97 and the spring member (first spring member, second spring member) 98 in addition to the one in the first embodiment. I have. For this reason, in the fourth embodiment, the spring member 98 is moved when the handrail belt 40 moves toward the moving direction defining roller 97 and the moving direction defining roller 97 is displaced in the same direction as the handrail belt 40. Thus, a force for restoring the original position to the moving direction defining roller 97 is applied.

  As described above, according to the passenger conveyor 1 and its handrail belt guiding device 90 according to the fourth embodiment, the handrail belt 40 is restricted when the handrail belt 40 is displaced, as in the second and third embodiments. The frequency of occurrence of refraction and knocking of the handrail belt 40 can be suppressed without the roller 94 coming into strong contact with the handrail belt 40. Furthermore, the frequency at which the regulating roller 94 is detached from the handrail belt 40 is reduced, and the situation where the guiding function is not performed can be suppressed. In addition, since the limiter 95 is provided, it is possible to return to an appropriate position relatively quickly as compared with the case where the limiter 95 is not provided, and it is possible to further suppress a situation where the guide function is not performed. Further, it is possible to avoid a state in which refraction or knocking of the handrail belt 40 easily occurs, such as the regulation roller 94 always contacting the handrail belt 40, and the frequency of occurrence of refraction or knocking of the handrail belt 40. Can be further suppressed.

  Further, since the handrail belt guide device 90 includes the movement direction defining roller 97, the handrail belt 40 can be guided more suitably. In addition, since the moving direction defining roller 97 is displaced in the same manner as the handrail belt 40, the moving direction defining roller 97 is less frequently detached from the handrail belt 40, and the situation where the guiding function is not performed is further suppressed. can do. Further, since the spring member 98 is provided, the restriction roller 94 can be returned to the original position at an early stage as compared with the case where the spring member 98 is not provided, and the frequency at which the restriction roller 94 does not perform the guiding function. Further suppression can be achieved.

  Further, according to the fourth embodiment, when the handrail belt 40 moves to the moving direction defining roller 97 side and the moving direction defining roller 97 moves in the same direction as the handrail belt, according to the fourth embodiment. The moving direction defining roller 97 is given a force for returning to the original position. For this reason, when the handrail belt 40 moves toward the moving direction defining roller 97 and repels the moving direction defining roller 97, the moving direction defining roller 97 is moved at an early stage as compared with the case where the spring member 98 is not provided. It can be returned to the position. Thereby, it is possible to suppress the frequency at which the movement direction defining roller 97 does not perform the guiding function.

  As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the above embodiments, and modifications may be made without departing from the spirit of the present invention. May be combined. For example, although the escalator has been described as an example of the passenger conveyor 1 in the above embodiment, the present invention is not limited thereto, and the passenger conveyor 1 may be a moving sidewalk.

However, the present invention is not limited to this, and the restriction roller 94 is handrailed by a very weak force. It may be in contact with the belt 40.

  In the fourth embodiment, a single spring member 98 is used, and when the regulating roller 94 and the moving direction defining roller 97 are repelled, a force is applied to return them to the initial position. The number of 98 is not limited to one and may be plural. Further, a spring member for returning the regulating roller 94 to the initial position and a spring member for returning the moving direction defining roller 97 to the initial position may be provided separately.
