Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a passenger belt conveyor for conveying people constituting, for example, a moving sidewalk.
[0002]
[Prior art]
A moving sidewalk for transporting a person to a predetermined position has a driving pulley and a driven pulley arranged at a predetermined interval in the transporting direction, and a passenger belt that spans between the driving pulley and the driven pulley. A user who is constituted by a belt conveyor and uses a moving sidewalk is transported to a predetermined position if he / she is on the conveyor belt, and can quickly reach a predetermined position by walking on the conveyor belt. Both end portions in the carrier side width direction of the conveyor belt are supported by support members such as support rollers, so that bending along the length direction of the conveyor belt is prevented.
[0003]
By the way, it is preferable that the moving sidewalk is configured so that the intermediate portion in the width direction does not bend when the user gets on the conveyor belt. If the conveyor belt bends when riding, the feeling of use will be significantly reduced. If the width of the conveyor belt is narrow enough to carry one person, even with a support structure in which only the carrier side width direction ends of the conveyor belt are supported by support members such as support rollers, the conveyor belt has sufficient width direction rigidity. Can be secured. However, recently, when a moving sidewalk is constructed, it is often required to have a sidewalk width that can carry two people side by side, that is, a width of a conveyor belt (for example, 1000 mm or more). When the conveyor belt is used, it is not possible to prevent the intermediate portion in the width direction of the conveyor belt from being bent when the user gets on the vehicle by simply supporting both ends in the carrier side width direction with the support members. In addition, if the conveyor belt is formed wide with a support structure in which only the carrier side width direction both ends of the conveyor belt are supported by the support member, the conveyor belt vibrates greatly when the user walks on the conveyor belt. When another user passes beside the user who is stopped above, an unpleasant vibration is transmitted to the stopped user.
[0004]
[Problems to be solved by the invention]
In order to prevent bending of the intermediate portion in the width direction of the wide conveyor belt and prevent the conveyor belt from vibrating greatly, it is conceivable to support the intermediate portion in the carrier side width direction of the conveyor belt with a support roller. However, in such a support structure of the conveyor belt, since a groove, a dent, or a gap is formed between the support rollers arranged in the transport direction, the support roller is interposed via the conveyor belt when the user gets on. This unevenness is transmitted to the user, giving the user unpleasant feeling.
[0005]
In order to prevent such discomfort to the user, it is conceivable to support the carrier side width direction intermediate portion of the conveyor belt with a plate-like support member entirely or substantially entirely in the transport direction. However, when such a support structure is adopted, there is no problem when the length of the conveyor belt is short and the width is narrow, but the conveyor belt to be bent is wide and has a large length of, for example, 50 m or more. Therefore, the sliding resistance when the conveyor belt slides on the plate-like support member becomes large, and a drive device for operating the passenger belt conveyor must be used with a high output.
[0006]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a passenger belt conveyor for transporting personnel that can be smoothly operated without using a high-power drive device and that does not cause discomfort to the user.
[0007]
To achieve this object, a passenger belt conveyor according to the present invention includes a pair of pulleys arranged at a predetermined interval in the transport direction or along the transport path, and an endless belt spanned between the pair of pulleys. A passenger belt conveyor for transporting personnel, comprising a conveyor belt, which is in contact with a carrier-side back surface of the conveyor belt and supports the carrier side of the conveyor belt, and extends in a conveying direction or a length direction. A low friction portion extending in the length direction is formed in the intermediate portion in the width direction on the back surface of the conveyor belt, and the receiving portion comes into contact with the low friction portion, thereby Supports the intermediate portion in the width direction on the carrier side, and the low friction portion is formed to have a width of 5% to 50% of the entire width of the conveyor belt. A. One receiving portion or a plurality of receiving portions are arranged at intervals in the width direction, for example. Since the intermediate portion in the width direction of the conveyor belt is supported by the receiving portion, the intermediate portion in the width direction of the conveyor belt is prevented from being greatly bent. Moreover, even if a user walks on a conveyor belt, a conveyor belt does not vibrate greatly.
[0008]
The receiving portion is in contact with or in contact with the low friction portion formed on the back surface of the conveyor belt, that is, the portion for reducing the frictional force between the receiving portion, or the carrier side of the conveyor belt with the low friction portion mounted thereon. Is supporting. Therefore, the sliding resistance between the conveyor belt and the receiving portion does not become excessive. By the way, the receiving portion has a sufficient support function for the conveyor belt, can receive the load from the user in a distributed manner, and gives the conveyor belt sufficient rigidity in the width direction expected. However, if the width of the low friction part (the sum of the widths of the low friction parts when multiple low friction parts are formed) is less than 5% of the total width of the conveyor belt, the receiving part It becomes impossible to secure an area enough to receive the whole with a margin. Further, if the width of the low friction part exceeds 50% of the entire width of the conveyor belt, the entire area of the back surface main body (the back surface other than the low friction part) of the conveyor belt may be insufficient, resulting in a loss of driving force from the driving pulley. There is. Therefore, in the present invention, the width of the low friction portion is set within a range of 5% to 50% of the entire width of the conveyor belt.
[0009]
Moreover, the low friction part should be formed indented from the back body of the Kobeya belt.
If the low friction part is not recessed from the back body, if the drive pulley has a simple cylindrical outer peripheral surface, sufficient frictional force between the drive pulley and the conveyor belt cannot be secured. The shape of the outer peripheral surface must be changed. However, if the low friction part is recessed, the simple cylindrical outer peripheral surface of the drive pulley will contact only the back body of the conveyor belt without contacting the low friction part. And since the back body of the conveyor belt is not made of a low friction material or in a low friction mode, that is, the back body of the conveyor belt generates sufficient frictional force with the pulley. Therefore, a large transmission loss of the driving force from the pulley to the conveyor belt does not occur. The low friction part can be formed annularly over the entire length of the conveyor belt, i.e. along the conveyor belt.
[0010]
If the conveyor belt is made of rubber and the low friction portion is formed by vulcanizing and bonding a low friction member to the back surface of the conveyor belt, the conveyor belt used in the present invention can be easily configured.
[0011]
In the present invention, it is possible to adopt a configuration in which both ends of the conveyor belt in the width direction are supported by support rollers and the intermediate portion in the width direction is supported by the receiving portion. However, in order to simplify the structure of the passenger belt conveyor, it is preferable that the support structure at both ends in the width direction of the conveyor belt is the same as the support structure at the intermediate portion in the width direction. Moreover, by comprising in this way, a user's usability | use_condition can be improved over the full width of a conveyor belt. Therefore, the following configuration can be adopted in the present invention.
A passenger belt conveyor for transporting personnel, comprising a pair of pulleys arranged at a predetermined interval in the transport direction, and an endless conveyor belt spanned between the pair of pulleys,
Further comprising a receiving portion extending in the conveying direction for supporting the carrier side of the conveyor belt in contact with the carrier side back surface of the conveyor belt;
A plurality of the receiving portions are arranged in the width direction, for example, with an interval so as to support the width direction both ends and the intermediate portion of the conveyor belt,
On the back surface of the conveyor belt, a plurality of low friction portions extending in the length direction are formed corresponding to the receiving portions,
Each of the receiving parts supports the carrier side of the conveyor belt by contacting the corresponding low friction part,
The passenger belt conveyor, wherein the low friction portion is formed to have a width of 5% to 50% of the entire width of the conveyor belt.

FIG. 1 is a perspective view schematically showing a passenger belt conveyor according to the present invention.
[0014]
A passenger belt conveyor 1 constituting a moving sidewalk is disposed at an end position (down position) and is rotatably disposed at a driving pulley 3 that is rotationally driven by a driving device (not shown) and a start position (riding position). The driven pulley 5, the drive pulley 3 and the rubber conveyor belt 7 stretched over the driven pulley 5, and a support structure 9 provided below the carrier side of the conveyor belt 7 and supporting the carrier side of the conveyor belt 7. The distance between the drive pulley 3 and the driven pulley 5 is set to about 100 m. The support structure 9 includes three steel frame-like receiving portions that extend in a straight line continuously from the position close to the driven pulley 5 to the position close to the drive pulley 3 in the conveying direction at equal intervals in the width direction. 11 and a steel support member 13 that supports the three frame-shaped receiving portions 11 by connecting them, and this frame-shaped receiving portion 11 is in contact with or in contact with the carrier side of the back surface 15 of the conveyor belt 7. Thus, the support structure 9 supports the carrier side of the conveyor belt 7. The frame-shaped receiving portions 11 on both sides support both ends in the width direction of the conveyor belt 7, and the center frame-shaped receiving portions 11 support the center portion in the width direction (intermediate portion in the width direction) of the conveyor belt 7.
[0015]
FIG. 2 is a cross-sectional view schematically showing the configuration of the passenger belt conveyor 1.
[0016]
The back surface 15 of the conveyor belt 7 is provided with recesses 17 formed in an annular shape extending in the entire length of the conveyor belt 7 at both ends and the center in the width direction corresponding to the frame-shaped receiving portions 11, respectively. A low friction member (for example, Teflon liner: Teflon is a registered trademark) is provided at the bottom (or the ceiling) of each of the recesses 17 provided at three intervals to form a low friction portion 19. The width of the conveyor belt 7 is approximately 1400 mm, the width of each low-friction portion (low-friction member) 19 is approximately 100 mm, and each low-friction portion 19 is 0.5 mm or more from the back surface body 21 of the conveyor belt 7. It is provided with a recess of 1.5 mm.

Here, the sum of the widths of the low friction portions 19 is set to be slightly more than 20% of the entire width of the conveyor belt 7. In general, the total width of the low friction portions is set to 5% to 50% of the entire width of the conveyor belt, but it is effective to set it to 10% to 30%. If the width of the low friction part is less than 10% of the entire width of the conveyor belt, the load reaction force per unit area applied from the receiving part of the narrow area to the low friction part becomes large. For example, the durability of the low friction member is reduced. May decrease. Further, if the width of the low friction part exceeds 30% of the entire width of the conveyor belt, a driving force transmission loss from the driving pulley may occur depending on the surrounding environment.
