Description

  The present invention relates to a passenger transport device represented by a moving sidewalk.

  2. Description of the Related Art Conventionally, a sidewalk (passenger transport device) that moves as a means for moving people has been used particularly in public facilities such as airports and stations, and leisure facilities such as golf courses (see, for example, Patent Document 1).

  A known moving sidewalk 10 is shown in FIGS. 7 is a side view of the moving sidewalk 10, FIG. 8A is an enlarged sectional view of the vicinity of the exit of the moving sidewalk, and FIG. 7B is a partial top view of the protection plate 30 in FIG. FIG. 9 is a perspective view of the vicinity of the exit of the moving sidewalk, and FIG. 10 is a cross-sectional view taken along line XX in FIG.

  The moving sidewalk 10 includes a conveyor belt 20 that rotates while being engaged with a pulley 18, a handrail 12 that is installed on both sides of the conveyor belt 20, and that rotates with the movement of the conveyor belt 20, and the passenger conveys the conveyor belt 20. A landing plate 14 disposed at a position before boarding the vehicle, a protection plate 16 disposed at the boundary between the landing plate 14 and the conveyance belt 20 (on the entrance side), and a position where passengers get off the conveyance belt 20 And a protective plate 30 disposed at the boundary between the landing plate 40 and the conveyor belt 20 (on the exit side). In addition, the conveyance direction in the said moving sidewalk 10 is right to left in FIG.

  A plurality of grooves 22 are formed in the transport belt 20 along the transport direction. A plurality of comb teeth 32 are formed on the protection plate 30, and each comb tooth 32 is loosely fitted in the groove 22.

JP 2002-3132 A

  One of the purposes of providing a plurality of grooves 22 in the conveyor belt 20 and installing a protective plate 30 having comb teeth 32 that fit loosely in the grooves 22 is generated between the conveyor belt 20 and the landing plate 40. The purpose is to prevent any object (for example, a coin or the like) from entering the gap. Certainly, like the moving sidewalk 10 in the known example, if a plurality of grooves 22 are provided in the conveyor belt 20, and the protective plate 30 is installed so that the comb teeth 32 are loosely fitted in the grooves 22, a certain degree or more will be provided. This is effective in preventing the entry of large objects.

  However, even with such a configuration, the problem that passenger clothes (for example, trousers or skirt hems) are caught is not completely solved.

  This invention makes it the subject to eliminate the problem of this pinching and to provide the passenger conveyance apparatus which a passenger can utilize in comfort.

  The present invention is a passenger conveyance device represented by a moving sidewalk, which is disposed at a boundary between a conveyance belt having a plurality of grooves formed along the conveyance direction, and the conveyance belt and a landing plate, and A protective plate having comb teeth loosely fitted in the grooves, and among the comb teeth, first and second comb teeth that are part of the comb teeth are arranged in a width direction between the protective plate and the conveyor belt. The above-described problem is solved by configuring so as to restrict relative movement.

  The inventor has found that the above problem is caused by the structure of a moving sidewalk as described below.

  Since the conveyor belt 20 used for a moving sidewalk has an endless track, a bent portion is always required, and is made of a material having some flexibility such as rubber. On the other hand, the transport belt needs to have a certain thickness or more from the viewpoint of ensuring durability, strength, and the like, and an allowable bending radius must be a certain level or more. That is, as shown in FIG. 8A, the conveyor belt 20 is guided downwardly in a smooth curve from the front of the landing plate 40. Then, if the comb teeth 32 of the protection plate 30 are configured to loosely fit into the grooves 22 provided on the conveyor belt 20, as shown in FIG. 8B, the plate body 31 moves away from the conveyance direction side. On the other hand, the comb teeth 32 need to be formed to protrude beyond a certain length. This is to ensure a safe and reliable movement of passengers by preventing an unnecessary angle and a certain level of difference between the conveyor belt 20 and the landing plate 40, and at the time of the application, This is an indispensable configuration. The presence of the comb teeth 32 projecting in the direction opposite to the conveying direction has caused the passenger's trousers, skirt hems, and the like to be caught.

  Further, the conveying belt 20 does not always stay at a fixed position in the width direction, but rotates slightly while swinging left and right (belt width direction) to a slight extent (about 4 to 6 mm). This is believed to be due to manufacturing errors in the overall belt width dimensions of the conveyor belts commonly supplied on the market and passenger load movement on the belts.

  As shown in FIG. 10, the interval W1 between the comb teeth provided on the protection plate is usually about 10 to 25 mm. This is because if it is further increased, a gap through which coins and the like easily pass will be generated. In terms of design, the gap G1 between the comb teeth 32 and the right side surface (one side surface) 22R of the groove 22 and the gap G2 between the comb teeth 32 and the left side surface (the other side surface) 22L of the groove 22 are at least 1 mm. The degree is secured. This is because, by securing a gap to some extent, even when clothes are hooked on the protruding comb teeth 32, there is left a room to escape from the gap.

  However, as described above, since the conveyor belt rotates while swinging to the left and right by about 4 to 6 mm, the gap is practically cancelled, and there is no room for the caught clothes to come out. Furthermore, there was a problem in that pinching was promoted.

  On the other hand, since the formation accuracy of the plurality of grooves themselves formed in the conveyor belt is significantly higher than the accuracy of the entire belt width, the inventor solves the problem by using such grooves. I got an idea.

  Therefore, the inventor controls the relative movement in the width direction between the conveyor belt and the protective plate by using some of the plurality of comb teeth as in the configuration described above, thereby allowing many others. The comb teeth are always configured to have a certain gap or more between the side surfaces of the grooves, and the problem has been solved.

  Further, in addition to the above configuration, a gap between the first comb tooth and one side surface of the groove in which the first comb tooth is loosely fitted is loosely fitted to a comb tooth other than the first comb tooth. And a gap between the second comb tooth and the other side face of the groove in which the second comb tooth is loosely fitted is a comb tooth other than the second comb tooth. The gap may be smaller than the gap between the groove and the other side of the groove.

  As a result, even when the conveyor belt moves left and right, the first and second comb teeth first come into contact with the side surfaces of the grooves, whereby the gap between the other comb teeth and the groove side surfaces becomes smaller than a certain level. Can be prevented.

  In addition to the above configuration, the gap between the first comb teeth and one side surface of the groove in which the first comb teeth loosely fit, and the second comb teeth and the second comb teeth The gap with the other side surface of the loosely fitting groove may be set to zero.

  Thereby, the relative movement of the conveyance belt and the protection plate in the width direction can be prevented almost completely.

  Further, in addition to the above configuration, a plurality of grooves of the transport belt are formed at equal intervals, the first comb teeth are installed in an offset state on the one side surface, and the second comb teeth are It may be installed in a state offset to the other side surface.

  Thereby, the conveyance belt distribute | circulated to a market can be utilized as it is.

  In addition to the above configuration, the protection plate is composed of a plurality of plate pieces divided in the width direction, and at least one plate piece is formed with first comb teeth and second comb teeth. You may do it.

  Thereby, according to the characteristic of each passenger conveyance apparatus, it becomes easy to adjust the number of the 1st, 2nd comb teeth in the whole comb teeth.

  Of course, the first comb teeth and the second comb teeth may be formed on each plate piece.

  As a result, the first and second comb teeth are arranged uniformly in the width direction of the conveyor belt, and the regulation of the conveyor belt can be made uniform over the entire belt.

  Further, in addition to the above configuration, the protection plate is configured by a plurality of plate small pieces divided in the width direction, and all the comb teeth are formed as first comb teeth on the plurality of plate small pieces. One plate piece and a second plate piece in which all the comb teeth are formed as second comb teeth may be included.

  Thereby, it is possible to freely set a position in which a gap between the comb teeth and the groove is desired within a certain range.

  In addition to the above configuration, the first and second plate pieces may be arranged on both ends of the protective plate.

  Accordingly, the position of the belt can be regulated at both ends of the conveyance belt which is less likely to be boarded by passengers, and a gap between the comb teeth and the groove can be secured in the central portion of the width of the belt.

  In addition to the above configuration, a plurality of comb teeth of the protective plate are formed at equal intervals, and one side surface of the groove in which the first comb teeth are loosely fitted is offset to the first comb tooth side. And the other side surface of the groove in which the second comb teeth are loosely fitted may be formed offset to the second comb teeth side.

  Thereby, it is realizable, without changing the design by the side of a protection plate (comb tooth).

  In addition to the above configuration, the protective plate itself may be configured to be slidable in the width direction.

  As a result, even when the amount of movement in the width direction (left-right direction) of the conveyor belt is large, the necessary gap can be maintained, and further, the stress in the width direction applied to the conveyor belt can be reduced, thereby The belt can be prevented from being twisted or bent.

  The “one side surface” in the present specification and claims means either the right side surface or the left side surface with reference to the transport direction of the transport belt. Similarly, the “other side surface” means a side surface on either the left side or the right side, that is, a side surface that is not one side surface, based on the transport direction of the transport belt.

  By applying the present invention, pinching of clothes can be prevented and passengers can use it with peace of mind.

  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a top view of the vicinity of a landing plate 140 of a passenger transport device 110 that is an example of an embodiment of the present invention, FIG. 2 is a partial cross-sectional view taken along line II-II in FIG. FIG. 3 is a partially enlarged sectional view taken along line III-III in FIG.

  For convenience of explanation, only the vicinity of the landing plate 140 of the passenger transport device 110 will be described. However, the other structure is substantially the same as the moving sidewalk 10 shown as a known example. In contrast to the known moving sidewalk 10, the same or similar parts in structure or operation will be described with the same reference numerals in the last two digits.

  The passenger transport device 110 includes a transport belt 120 having a plurality of grooves 122 (not shown in FIG. 1) formed along the transport direction, and a landing plate disposed on the transport direction side of the transport belt 120. 140 and a protective plate 130 having comb teeth 132 that are disposed at the boundary between the conveyor belt 120 and the landing plate 140 and loosely fit into the grooves 122. Furthermore, the side structure 160 used as the frame | skeleton of the said passenger conveyance apparatus is arrange | positioned at the conveyance direction right and left.

  The protection plate 130 is composed of a plurality of small plate pieces 171 to 181 divided in the width direction. Comb teeth 132 are formed on each of the plate small pieces 171 to 181 (details will be described later). In addition, each of the plate small pieces 171 to 181 is installed and fixed to the landing plate 140 by bolts 134.

  At both ends in the longitudinal direction of the landing plate 140, a connecting member 142 and a support member 146 are respectively installed. A first roller 144 is rotatably fixed to the connecting member 142. The first roller 144 is placed on the side structure 160 and can move in the left-right direction (belt width direction) by a gap G (gap between the connecting member 142 and the side structure 160). Has been. In other words, the landing plate 140 (and the protective plate 130) can be slid in the left-right direction with respect to the side structure 160.

  On the other hand, the landing plate 140 (and also the protective plate 130) is pivotally supported by the support member 146 so as to be slidable in the left-right direction with respect to the side structure 160. It is set as the structure which can accept | permit the slide of the left-right direction. At the same time, the landing plate 140 is rotatably supported around the axis O1. With this configuration, even when clothes or the like are sandwiched between the comb teeth 132, the lifting plate 140 is lifted upward (toward the front side in FIG. 1) so that force can be released.

  Moreover, the 2nd roller support plate 148 which supports the 2nd roller 150 is installed and fixed to the lower surface side left-right end of the landing plate 140 (refer FIG. 2, FIG. 3). As shown in FIG. 3, the second roller 150 is rotatable while being in contact with both end surfaces of the conveyance belt 120 in the width direction. That is, the position of the conveyance belt 120 in the left-right direction (belt width direction) is restricted.

  In addition, the conveyance belt 120 is guided by the pulley 118 at a position in front of the landing plate 140 and falls downward, and is sequentially sent in the landing direction.

  Next, the protection plate 130 will be described. The protective plate 130 is shown in FIGS. FIG. 4A is a plan view of a small plate constituting the protective plate 130, FIG. 4B is a side view seen from the arrow B side, and FIG. 4C is a cross-sectional view taken along the line CC. ) Is a cross-sectional view taken along line DD. FIG. 5 is a perspective view of a small plate piece (bolt hole omitted).

  The protection plate 130 includes a plate body 131 and comb teeth 132, and the comb teeth 132 are projected from the plate body 131. In the present embodiment, the comb teeth 132 are formed at equal intervals, but the equal intervals are not essential components. Reference numeral 135 denotes a bolt hole for fixing the protective plate 130 to the landing plate 140.

  Next, a loosely fitted state between the groove 122 formed on the conveyor belt 120 and the comb teeth 132 formed on the protective plate 130 will be described with reference to FIG. FIG. 6 is an enlarged partial cross-sectional view taken along line VI-VI in FIG.

  Each of the small plate pieces 171 to 181 constituting the protective plate 130 is formed with comb teeth 132. The comb teeth 132 are formed in a size that can be loosely fitted in the grooves 122 with a gap. Yes. Of these comb teeth 132, the first comb teeth 132-1 formed on the first plate piece 171 disposed at the right end with respect to the transport direction are on one side surface of the groove 122 (in this embodiment). Are arranged near the right side surface in the traveling direction. On the other hand, the second comb tooth 132-2 formed on the second plate piece 181 disposed at the left end with respect to the transport direction is the other side surface side of the groove 122 (in this embodiment, the left side surface in the traveling direction). It is arranged and arranged. That is, the gap between the first comb tooth 132-1 and one side surface of the groove 122 in which the first comb tooth 132-1 is loosely fitted is a comb tooth other than the first comb tooth 132-1. 132 and a groove (groove) 122 in which each of the second comb teeth 132-2 and the second comb teeth 132-2 are loosely fitted. The gap with the other side surface is configured to be smaller than the gap between the comb teeth other than the second comb tooth 132-2 and the other side surface of the groove 122 in which each loosely fits. That is, the first comb teeth 132-1 restrict the movement of the conveyor belt 120 in the left direction and the second comb teeth 132-2 restrict the movement of the conveyor belt 120 in the right direction based on the conveyance direction. is doing. Accordingly, among the comb teeth 132 formed on the entire protection plate 130, the first and second comb teeth 132-1 and 132-2, which are some of the comb teeth 132, are formed between the protection plate 130 and the conveyor belt 120. The relative movement in the width direction is restricted.

  Next, the effect | action of the said passenger conveyance apparatus 110 is demonstrated.

  When the passenger transport device 110 is operated, the transport belt 120 starts to rotate. Although the conveyance belt 120 is restricted from moving in the left-right direction (belt width direction) by the second roller 150 described above, the manufacturing accuracy of the belt width dimension of the conveyance belt 120 is not so high. Millimeters will swing left and right. Then, since the belt moves more than the gap amount between the comb teeth 132 and the side surfaces of the grooves 122, the gap set in the design is effectively canceled out.

  However, in the passenger transport apparatus 110 to which the present invention is applied, even if the transport belt 120 moves left and right due to the presence of the first and second comb teeth 132-1 and 132-2 described above, first, The first and second comb teeth 132-1 and 132-2 are in contact with the side surface of the groove 122 on the small gap side, so that the gaps between the other comb teeth 132 and the side surface of the groove 122 become smaller than a certain level. It is preventing. That is, many of the comb teeth 132 are always located within the groove 122 with a certain gap or more, and even if a passenger's clothes are caught on the protruding comb teeth 132 by any chance. It is possible to get out of the gap.

  It is of course possible to configure so that the “one side surface” and the “other side surface” described in the above embodiments are reversed.

  Note that the gap between the first comb teeth 132-1 and one side surface of the groove 122 in which the first comb teeth 132-1 are loosely fitted, and the second comb teeth 132-2 and the second comb. You may comprise so that the clearance gap with the other side surface of the groove | channel 122 in which the tooth | gear 132-2 loosely fits may be "zero" by design. By doing so, relative movement in the width direction between the conveyor belt 120 and the protective plate 130 can be prevented almost completely.

  In this way, if the first and second comb teeth 132-1 and 132-2 are arranged at both ends of the belt, the portion where the passenger is less likely to board (that is, the portion where the clothes or the like is less likely to approach). Therefore, the gap between the comb teeth 132 and the groove 122 can be secured in the central portion of the width of the belt where passengers are likely to board.

  In this embodiment, the landing plate 140 to which the protection plate 130 is fixed is configured to be slidable in the left-right direction by the gap G. This means that even when the amount of movement (swing) in the left-right direction of the conveyance belt 120 is large, the protective plate 130 can follow the conveyance belt 120 as much as the gap G as a unit. That is, it is possible to prevent twisting and bending of the conveyor belt 120 by reducing the stress in the width direction applied to the conveyor belt 120 while maintaining a necessary gap between the comb teeth 132 and the groove 122. ing. Furthermore, the sliding can reduce the frictional force with the side surface of the groove 122 with which the first and second comb teeth 132-1 and 132-2 come into contact, and wear of the comb teeth 132 and the groove 122 is reduced.

  In the present embodiment, among the plate small pieces 171 to 181 constituting the protective plate 130, all the comb teeth of the first plate small piece 171 located at one end of the protective plate 130 are defined as the first comb teeth 132-1. All the comb teeth of the second plate piece 181 disposed at the other end of the protective plate 130 are arranged as second comb teeth 132-2 close to (offset with) the side surface of the groove 122. . However, the embodiment of the present invention is not limited to such a configuration. For example, it is also possible to employ a protective plate in which a first comb tooth and a second comb tooth are formed on each of the plurality of plate small pieces 171 to 181. With such a configuration, a protective plate can be configured by combining plate pieces of the same shape, and the manufacturing cost of the protective plate can be reduced. Moreover, even if it is consumed due to use, the same parts can always be substituted, and the stock amount of repair parts may be small. In addition, the first and second comb teeth are arranged uniformly in the width direction of the transport belt, and the regulation of the transport belt can be made uniform over the entire belt. In addition, although demonstrated as a structure by which the 1st comb tooth 132-1 and the 2nd comb tooth 132-2 are formed in all the several plate small pieces, it is 1st only to one part plate small piece. It is also possible to form the comb teeth 132-1 and the second comb teeth 132-2. By comprising in this way, according to the characteristic of each passenger conveyance apparatus, it becomes easy to adjust the number of the 1st, 2nd comb teeth in the whole comb teeth.

  In addition, it is not always restricted by offsetting the comb teeth themselves with respect to the plate body, but only the specific plate pieces are offset together with the plate pieces by inserting shims or spacers without changing the structure of the comb teeth. It is also possible to regulate it. Furthermore, it is possible to regulate by offsetting the “groove” itself formed in the belt. If comprised in this way, there exists an advantage which can be utilized as it is, without requiring the design change of the conventional comb-tooth (further, protection plate).

  The present invention can be applied not only to a case where a passenger is directly transported on a belt, but also to a transport device that transports, for example, a passenger on a cart together with the cart.
