Description

  The present invention relates to a passenger transport device.

  In recent years, passenger transport apparatuses called “moving sidewalks” or “moving sidewalks” have started to be installed at airports, large stations, or connecting passages thereof.

  An example is shown in FIGS. This apparatus includes a transport belt (transport body) 2 that moves on an endless track while passengers are on board. A plurality of grooves 4 are formed on the outer surface of the transport belt 2 along the transport direction X.

  In addition, a comb-tooth plate 8 is disposed at the boundary between the conveyor belt 2 and the exit-side floor surface 6. The comb tooth plate 8 is composed of a plate body 10 and comb teeth 12. The comb teeth 12 protrude beyond the rear end 14 of the plate body 10 to the rear side in the conveying direction, and have a shape in which a part of the comb teeth 12 enters the plurality of grooves 4. This is a configuration for preventing foreign matter on the riding surface 16 from easily entering the apparatus when part of the comb teeth 12 enters the groove 4 (Patent Document 1, etc.).

JP 2002-3132 A

  However, although the conventional passenger transport device can cope well with relatively hard foreign objects, for example, people with long trousers or skirt hems, fraying, etc. have occurred and grounded on the boarding surface If a person who is in a state of boarding is on board, these fabrics and frayed thread tips are pinched between the groove and the comb tooth plate, and part of the clothing body is damaged. I sometimes did.

  The present invention has been made in view of such circumstances, and a more effective phenomenon is that a part of such clothes or a soft accessory that has been inadvertently dropped is sandwiched between the groove and the comb tooth plate. It is an object of the present invention to provide a passenger transport device that can be prevented.

  The present invention is a transport body in which a plurality of grooves are formed along the transport direction on a boarding surface on which a passenger is boarded, and is disposed at a boundary between the transport body and the exit side floor surface, and a plate body, A comb tooth plate having a comb tooth projecting from the surface of the plate body and having a part of the comb body entering a groove of the transport body; and a comb tooth of the comb tooth plate The above-mentioned problem is solved by adopting a configuration in which the rearmost end in the transport direction is positioned and installed at the same or lower height as the bottom surface of the groove in the transport section of the passenger of the transport body It is.

  Further, the present invention is the same passenger transport device, wherein the rear end of the comb body in the transport direction of the plate body is equal to or lower than the height of the bottom surface of the groove in the transport section of the passenger of the transport body. In addition, the above-described problem is solved by adopting a configuration that is positioned and installed.

  Further, the present invention is the same passenger transport device, wherein the uppermost portion of the comb teeth in the vertical direction at the rearmost end in the transport direction of the plate body of the comb tooth plate is the height of the rearmost end in the transport direction of the plate body. In addition, the above-mentioned object is achieved by adopting a configuration that is positioned and installed at a height higher than the depth of the groove of the carrier.

  As a result of repeating enormous entrainment tests under various conditions in the development stage of the present invention, as one mechanism when entrainment occurs, many foreign substances that have reached the vicinity of the comb tooth plate at the exit are It was confirmed again that it was proceeding as it was near the gap.

  The comb-teeth plate is disposed so as to stand up in the entire width direction with respect to the conveyor belt so as to prevent foreign matter existing on the conveyor belt from being taken into the apparatus. It can be said that the foreign matter on the surface advances toward the gap between the comb-tooth plate and the conveyor belt.

  However, soft items such as clothes tend to get caught in the gap, and once caught, they tend to be drawn further by the progress of the conveyor belt, so if you can guide foreign objects such as clothes away from the gap, There is a possibility that entry into the gap can also be reduced.

  The carrier is moving horizontally at a considerable speed. Accordingly, the foreign matter that moves together while being placed on the carrier also proceeds horizontally at a considerable speed. On the other hand, the transport body always has a downwardly inclined portion in order to sink under the comb tooth plate. From this point of view, in the present invention, the rear end of the comb teeth in the conveyance direction of the comb teeth is positioned at the same or lower height as the bottom surface of the groove in the passenger conveyance section of the conveyance body. Configured to be installed.

  As a result, many foreign substances tend to collide with the ridge line part slightly above the gap due to inertia or due to the shape of the foreign substance itself, and (through the ridge line part) without entering the gap. Then, it is led directly to the top of the comb-tooth plate.

  For the same purpose, in the present invention, the rear end of the comb body in the transport direction of the plate body is positioned at the same or lower height as the bottom surface of the groove in the transport section of the passenger of the transport body. Installed. As a result, when the foreign matter has reached the vicinity of the rearmost end of the plate main body, a large amount of foreign matter has already been guided to a position higher than the position at which the foreign matter comes into contact with the comb teeth along the ridge line of the comb teeth. In other words, it is possible to prevent foreign matter from entering from the gap between the plate body and the transport body with a very high probability.

  Furthermore, for the same purpose, in the present invention, the uppermost portion of the comb teeth in the vertical direction at the rearmost end of the plate body of the comb tooth plate is higher than the height of the rearmost end of the plate body in the transport direction itself. Positioned and installed at a height higher than the depth of the groove of the carrier. As a result, the top of the comb teeth can be maintained at a very high height with respect to the height of the plate body conveyance direction rearmost end. The probability of entering into the gap can be reduced, and foreign matter can be prevented from entering through the gap.

  Experiments have also revealed the optimal design range for the location of each part. This will be described in detail later.

  It is possible to guide clothes and the like so as not to go to the gap between the comb-tooth plate and the conveying body, and to prevent the clothes and the like from being caught in the gap.

  Hereinafter, an example of an embodiment of a passenger conveyance device according to the present invention will be described in detail based on the drawings.

  2 and 3 show an overall outline of a passenger conveyance device 20 to which the present invention is applied. The passenger conveyance device 20 includes a conveyance belt (conveyance body) 22 having a boarding surface 21 on which a passenger rides, and a comb-tooth plate 26 disposed at the boundary between the conveyance belt 22 and the exit-side floor surface 24. . The transport belt 22 includes a plurality of grooves 30 on the outer surface (portion other than the grooves) 28 along the transport direction X. The comb tooth plate 26 includes a plate main body 44 having a rectangular plane and a plurality of comb teeth 46 protruding from the surface thereof.

  In addition, in this specification, a boarding surface shall refer to outer surfaces other than the groove | channel of the conveyance belt in the area (horizontal area) R which conveys a passenger. Further, the bottom surface of the groove of the conveyor belt in the section (horizontal section) R for transporting passengers is referred to as a horizontal section bottom surface.

  In the present embodiment, the comb tooth plate 26 having such a configuration is attached to a position slightly offset from the end V <b> 1 of the riding surface 21 of the transport belt 22 to the front side in the transport direction X. Accordingly, the second surface PL2 including the outer surface 28 of the conveyor belt 22 exists on the front side in the conveyance direction of the boarding surface 21 (first surface PL1). That is, the second surface PL2 is a surface having a curved surface that is inclined downward toward the front side in the transport direction.

  On the other hand, as shown in FIG. 2, in this embodiment, the comb-teeth plate 26 is composed of eleven plate pieces 26 </ b> A to 26 </ b> K, and each plate piece 26 </ b> A to 26 </ b> K is integrated with the descender side floor surface 24. Has been. The integrated comb teeth plate 26 is assembled so that a part of the comb teeth 46 enters the groove 30 with a predetermined belt width direction gap S1 (not shown).

  The plate main body 44 of the comb tooth plate 26 is formed with an inclined portion 48 that gradually becomes thinner from the vicinity of the central portion C in the transport direction X toward the rear side in the transport direction X.

  The comb teeth 46 of the comb tooth plate 26 rise relative to the inclined portion 48 due to the presence of the inclined portion 48 toward the riding surface 21, and the rear end of the inclined portion 48 (the conveying direction of the plate body 44). Projecting toward the rear side in the transport direction X beyond the rear end (hereinafter simply referred to as the rear end of the main body) 50.

  As shown in FIG. 1, the comb teeth 46 have ridge portions 52. The ridge line portion 52 is inclined upward toward the front side in the transport direction X, and a surface including the ridge line portion 52 constitutes the third surface PL3.

  Eventually, in this embodiment, the surface including the riding surface 21 is the first surface PL1, the surface including the outer surface 28 of the conveyor belt 22 descending on the front side in the conveying direction from the riding surface 21 is the second surface PL2, and the comb tooth plate 26. When the surface including the ridge line portion 52 of the comb teeth 46 is the third surface PL3, the second surface PL2 and the third surface PL3 form a recess SP1 having a depth Dm with respect to the first surface PL1. Will be. Note that the surface including the uppermost portion 40 of the comb-tooth plate 26 constituting the fourth surface PL4 (= the descending entrance floor surface 24) is flush with the first surface PL1 including the riding surface 21.

  A gap S2 of 3 mm or less including zero is provided between the outer surface 28 of the conveyor belt 22 and the lower position of the main body end 50 of the comb-tooth plate 26. Further, a gap S3 of 0.1 mm to 2.0 mm is provided between the bottom surface 31 of the groove 30 of the conveyor belt 22 and the lower position of the rearmost end 62 of the comb teeth 46.

  The narrower these gaps S2, S3, the harder it is for clothes to enter, but when it is set to a value very close to 0 or zero, it has the property of being difficult to release once it is pinched for some reason. Therefore, the material of the conveyor belt 22, the curvature, the installation location, and the like are taken into consideration, and the selection is appropriately made within this range.

  The reason why the optimum range of the gap S3 is set to be narrower than the optimum range of the gap S2 is that foreign matters such as clothes are more likely to enter the gap S3 than the gap S2. The reason why the gap S2 may be a little wider is that foreign matter such as clothing that has reached the comb-tooth plate 26 is lifted upward along the ridgeline portion 52, and the probability of entering through the gap S2 is drastically reduced. .

  The height Z3 of the rear end of the comb teeth 46 (hereinafter simply referred to as the comb end) is the horizontal bottom surface (that is, the bottom surface of the bottom surface 31 of the groove 30 corresponding to the riding surface 21 of the conveyor belt 22). The lower width H2 is set lower than the height Z2 of 31A. The lowering width H2 is set to a height in the range of 0 to 1.3d, where d is the depth of the groove 30. Specifically, in this embodiment, the depth d of the groove 30 is about 6 mm, and therefore is preferably about 0 to 8 mm, more preferably about 4 ± 2 mm. The appropriate range exists because the effect of causing the foreign object to collide with the upper side of the gap S3 can be obtained as the lowering width H2 is increased, and if it is too large, it reaches the comb tooth plate 26 after the end V1 of the riding surface 21. This is because the distance La becomes large and the passenger feels uncomfortable about the downward slope.

  In this embodiment, specifically, the lowering width H2 is set to 4 mm.

  As a result, as a result, the height Z3 of the comb tooth rear end 62 is set lower by a dimension H5 (= H2 + d) when viewed from the height Z1 of the riding surface PL1.

  On the other hand, the height Z4 of the body rear end 50 of the comb tooth plate 26 is set to be lower than the height Z3 of the comb tooth rear end 62 by a lowering width H3. The lowering width H3 is set in a range of 0 to 1.5d. It is preferable that the height Z4 of the main body rear end 50 is lower than the height Z3 of the comb tooth last end 62 by a width H3. The probability that foreign matter that has escaped from entering the gap S3 enters the gap S2. This is to lower it. On the other hand, there is an upper limit on the appropriate value of the lowering width H3 because if the height Z4 of the main body rear end 50 is made too low, it becomes difficult to take out or discharge the foreign matter that has escaped from entering the gaps S2 and S3. It is.

  For this reason, the reduction width H3 is also important in relation to the reduction width H6 (= H2 + H3) from the horizontal bottom surface 31A. Specifically, the reduction width H6 is about 0 to 2.8d from the horizontal bottom surface 31A. It is preferable that the depth is up to. In terms of absolute value, a range of 0 to 16 mm, preferably a range of 8 ± 2 mm is optimal.

  In this embodiment, the lowering width H6 from the horizontal portion bottom surface 31A is set to about 7 mm, but within the above range, it is appropriately set according to the installation situation, the actual depth d of the groove 30, and the like. Good.

  On the other hand, the uppermost portion 40 of the comb teeth 46 in the vertical direction at the main body rear end 50 of the comb tooth plate 26 is positioned and installed at a height higher by the dimension H4 than the height Z4 of the main body rear end 50 itself. Yes. The dimension H4 is preferably set in a range of 2d ± 0.7d. Specifically, the dimension H4 is the same as the case where the fourth surface PL4 including the uppermost portion 40 of the comb tooth plate 26 is flush with the riding surface 21 (first surface PL1) as in the present embodiment. Is the same as the lowered width H1 from the boarding surface 21 to the rearmost end 50 of the main body. Since it is not preferable that the uppermost portion 40 of the comb teeth 46 is higher than the riding surface 21, the upper limit of the dimension H4 is the lowered width H1 from the riding surface 21 to the main body rear end 50. Securing the dimension H4 for the comb teeth 46 at the height Z4 of the main body rear end 50 means that the foreign objects move from the comb rear end 62 to the main body last end 50 while the foreign objects move to the ridge line of the comb teeth 46. It means that it is guided away from the gap S2 by the dimension H4 along the portion 52.

  In the present embodiment, the comb tooth 46 of the comb tooth plate 26 has a range of a portion 58 (a black-filled portion) 58 existing below the height Z4 of the main body rear end 50 within the range of the main body rear end 50. It exists only on the rear side X1 in the transport direction (does not exist on the front side X2). That is, in the present embodiment, the lower part of the main body rear end 50 is shifted from the “lower side in the transport direction front side X2” of the main body rear end 50 to the “lower side in the transport direction rear side X1”. From another point of view, a part of the comb teeth 46 (portion indicated by cross hunting in the drawing) 60 on the “conveying belt rear side X1 only” 60 of the conveying belt 22 from the rear end 50 of the main body is conveyed by the conveying belt. It means that it has entered into the groove 30 of 22. Further, the gap S4 between the lower portion 49 of the comb tooth 46 and the bottom surface 31 of the groove 30 is gradually enlarged toward the front side X2 in the transport direction. These configurations are for securing a large space 70 near the lower side of the rear end 50 of the main body.

  Next, the operation of the passenger transport device 20 according to this embodiment will be described.

  As an entrainment path for passenger clothes and the like, first, the intrusion of foreign matter into the gap S3 between the lower side of the comb tooth rear end 62 of the comb tooth plate 26 and the bottom surface 31 of the groove 30 of the conveyor belt 22 will be described.

  In this embodiment, the height Z3 of the comb tooth rear end 62 of the comb tooth plate 26 is lower by the dimension H5 than the height Z1 of the riding surface PL1, and further, the height H2 is lower than the height Z2 of the horizontal bottom surface 31A. It is set to a low height. Therefore, since the conveyor belt 22 is driven horizontally at a considerably high speed, not only foreign matters existing on the boarding surface PL1, but also foreign matters existing on the bottom surface 31 of the groove 30 are caused by inertia ( (Alternatively, depending on the shape of the foreign substance itself), it comes into contact with the ridge line portion 52 slightly above the comb tooth rear end 62 and is directly guided by the ridge line portion 52 and rides on the comb tooth plate 26. Therefore, the phenomenon itself that clothes or the like enter the gap S3 below the comb tooth end 62 is very difficult to occur.

  Further, even if clothes or the like enter through the narrow gap S3, as is apparent from FIG. 1, the gap S4 between the lower portion 49 of the comb teeth 46 and the bottom surface 31 of the groove 30 faces the front side X2 in the transport direction. Therefore, a state in which the clothing that has entered is further engulfed with the movement of the conveying belt 22 is not formed.

  Next, the gap S2 between the lower side of the plate body rearmost end 50 of the comb tooth plate 26 and the outer surface 28 of the conveyor belt 22 will be described.

  In the present embodiment, the main body rearmost end 50 is lower than the rearmost end 62 (Z3) of the comb teeth 46 by the lowering width H3, and the height Z4 is lower than the riding surface PL1 (Z1) by the lowering width H1. It is said that. Therefore, when clothes or the like that have been present on the boarding surface PL1 so far reach the vicinity of the main body rear end 50 in the transport direction X, the main body rear end 50 along the ridge line portion 52 of the comb tooth 46 Is also lifted to a position higher by the dimension H4, and the probability that clothes and the like enter from the gap S2 is drastically reduced.

  Even if clothing or the like enters the lower side of the plate main body 44 from the gap S2, the lower end of the main body 44 (the front side X2 in the transport direction of the main body rear end 50) is more than the rear end of the main body 50. Since there is no portion on the lower side, an extremely wide space 70 is secured, and further entrainment due to the narrow gap between the comb teeth and the conveying belt as in the conventional case does not occur. Therefore, by pulling it up with a light force, it is possible to easily take out clothes and the like that have once entered the lower side of the plate body 44 with little damage.

  FIG. 4 shows an example of still another embodiment of the present invention.

  In this embodiment, a transport pallet 222 is used as the transport body. Some passenger transport devices may require longer or wider types depending on the installation location. In the case of such a passenger transport device, if the main material of the transport body is composed of a steel pallet 223, better results can be obtained in terms of strength, durability, or stability when boarding. There are many cases. Each pallet 223 is connected in a manner attached to the chain 225. When a pallet structure is adopted as the carrier, each pallet 223 has a slight gap S5 immediately before reaching the comb-tooth plate 244, but this gap increases toward the comb-tooth plate 224. For this reason, clothes or the like that have entered the gap S5 are not strongly pinched again. The positional relationship between the parts is almost the same as in the previous embodiment. Therefore, even when such a pallet type transport body is used, it can be applied in the same manner as in the previous embodiment, and a corresponding effect can be obtained.

  In this embodiment as well, the other configurations are the same as those of the previous embodiment. Therefore, the same reference numerals are given to the corresponding parts in the figure, but the duplicated explanation is omitted. To do.

  The present invention can be widely applied to passenger conveyance devices that convey passengers such as moving walkways while on board.
