Description

  The present invention relates to a belt-type passenger conveyor used as a “moving sidewalk” for carrying and transporting passengers, and more particularly to a drive mechanism thereof.

  A belt-type passenger conveyor used as a moving sidewalk has an endless annular belt. The endless annular belt is supported by a plurality of guide rollers installed between the entrance and the exit, and is circulated by the drive unit. A conventional passenger conveyor has a configuration in which a belt is driven by a pulley disposed at a folded portion of the belt. Many drive units are provided near the entrance or near the exit.

  The passenger conveyor has a handrail belt prepared for a passenger to hold as a support during boarding. The handrail belt is an endless ring and is wound around the balustrade. The handrail belt circulates so that it moves along the railing from the entrance to the exit and is returned through the conveyor device from the exit to the entrance. The handrail belt is driven at the same speed as the belt by a handrail drive mechanism provided in the conveyor device. As a general handrail drive mechanism, there is known a mechanism in which a handrail belt is sandwiched between a driving roller and a pressure roller, and the handrail belt is gripped and driven by a frictional force.

  In recent years, in order to improve passenger transportation efficiency, belt acceleration passenger belts of intermediate acceleration type where the belt speed in the vicinity of the entrance and exit is about the same as the conventional speed but the belt speed in the middle part is fast have been seen. The

  For example, the “transport device” described in Japanese Patent No. 3308298 has a low-speed transfer unit having a low moving speed and a high-speed transfer unit having a high moving speed. This transport device realizes an intermediate acceleration type by transferring passengers from a low-speed transfer unit to a high-speed transfer unit and from the high-speed transfer unit to the low-speed transfer unit.

  The “moving sidewalk” described in Japanese Patent Laid-Open No. 7-232828 has a plurality of belts having different transfer speeds arranged in series. A large number of stretchable pallets that can be stretched are wound around these belts. The telescopic pallet is circulated and driven by a belt. This “moving sidewalk” realizes an intermediate acceleration type by expanding and contracting the telescopic pallet according to the speed of each belt.

  However, as the passenger conveyor has a longer transport distance, the load on the belt increases. Therefore, there may be a case where a sufficient driving force cannot be transmitted only by the driving unit arranged in the belt folding portion. For example, the belt pulsates back and forth slowly. Such a problem is not limited to the belt-type moving sidewalk, but is common to all belt-type conveyor devices having a long moving distance.

  Even when the belt is long as described above, the belt can be driven by pinching the belt between the driving roller and the pressure roller to generate a frictional force. However, the belt may have excessive tension or surface pressure depending on the operating conditions. Will receive. For this reason, there exists a possibility that the lifetime of a belt may fall.

  Further, among the passenger conveyors classified as the intermediate acceleration type, in the “transportation device” described in Japanese Patent No. 3308298, the speed change in the transfer portion between the transfer portions having different transfer speeds is discontinuous. . For this reason, passengers may stagger or roll at the transfer section, which is not preferable for passenger safety.

  Further, in the “moving sidewalk” described in Japanese Patent Laid-Open No. 7-232828, when the telescopic pallet is extended, a mechanical gap is formed on the telescopic pallet. If foreign objects such as pebbles get caught in the gap, there is a possibility that the expansion / contraction pallet cannot be physically contracted. Not only is the transfer speed not decelerated, but the telescopic pallet cannot be reversed at the turn-back portion, which is undesirable for passenger safety.

  Therefore, in a belt-type passenger conveyor with a long conveying distance, an intermediate acceleration type belt that can be driven appropriately and smoothly with less burden on the belt portion and ensuring safety for passengers during operation. There is a need for a type passenger conveyor.

The belt-type passenger conveyor according to the present invention has a belt for carrying and transporting passengers, and a drive system for circulating at least the belt in the main frame. The belt is configured in a double structure having a boarding belt and a drive belt. The boarding belt circulates along a first circulation path provided in the main frame. Drive belt, circulates along the second circulation path provided inside the first circulation path. And a drive belt transmits the driving force for circulating a boarding belt to a boarding belt by contacting a part of inner peripheral surface of a boarding belt. The drive system includes a drive mechanism that generates a drive force for circulating the drive belt.

  It is preferable to provide a plurality of drive belts. In this case, the plurality of drive belts are in contact with the boarding belt at different portions of the first circulation path, and drive the boarding belt.

  Preferably, the drive belt contacts the boarding belt in at least a part of the first circulation path where at least a passenger rides on the boarding belt, and transmits the driving force to the boarding belt there.

By doing in this way, the intermediate acceleration type belt-type passenger conveyor which made the speed of the center part high with respect to the speed of a boarding gate and a exit can be comprised. For example, the second drive belt is circulated by the second drive mechanism at a speed V2 greater than the speed V1 of the first drive belt circulated by the first drive mechanism. In this case, a boarding belt having a structure that can expand and contract in the circulation direction is applied.
The driving belt transmits the driving force from the driving belt to the boarding belt by meshing with the surface of the boarding belt contacting the first and second driving belts and the surface of the first and second driving belts contacting the boarding belt. The tooth gap is formed, and the pitch P2 of the tooth groove formed on the second driving belt is set to V2 / V1 times the pitch P1 of the tooth groove formed on the first driving belt, so that the driving force is Improve transmission efficiency .

  In this case, in order to smoothly change the circulation speed of the boarding belt, the boarding belt is provided between a region where the first driving belt contacts the boarding belt and a region where the second driving belt contacts the boarding belt. There is further provided at least one roller that is in contact with each other to provide a driving force.

  The belt type passenger conveyor according to the embodiment of the present invention will be described below with reference to the drawings.

[First Embodiment]
It has a belt for carrying and transporting passengers and a drive system for circulating at least the belt in the main frame. The belt is configured in a double structure having a boarding belt and a drive belt. The boarding belt circulates along a first circulation path provided in the main frame. The drive belt circulates along a second circulation path circulation path provided inside the first circulation path. And a drive belt transmits the driving force for circulating a boarding belt to a boarding belt by contacting at least one part of the internal peripheral surface of a boarding belt. The drive system includes a drive mechanism that generates a drive force for circulating the drive belt.

  First, a first embodiment will be described with reference to FIGS. The overall configuration of the passenger conveyor is shown in FIG. The passenger conveyor 1 is a belt-type passenger conveyor provided with a belt for carrying and transporting passengers. The belt is circulated in the main frame 2 by a drive system. The belt is constituted by the boarding belt 3 and the drive belt 4 in a double manner.

  The boarding belt 3 circulates along a predetermined circulation path (first circulation path) provided in the main frame 2. The driving belt 4 circulates and moves along a second circulation path provided inside the first circulation path. The driving belt 4 (4 a, 4 b, 4 c) is in contact with the inner peripheral surface of the riding belt 3, thereby transmitting a driving force for circulating the riding belt 3 to the riding belt 3. Moreover, the passenger conveyor 1 is provided with the drive mechanism 5 (5a, 5b, 5c) which drives the drive belt 4 (4a, 4b, 4c).

  In the embodiment, the guide means 6 of the drive belt 4 shown in FIGS. 1 and 2 is constituted by a guide roller or the like. The guide means 6 is disposed inside the main frame 2. The guide means 6 includes a tensioner that applies an appropriate tension to the drive belt 4.

  Three drive belts 4 are provided so as to be arranged in series along the longitudinal direction of the main frame 2 serving as the transport direction. On the other hand, the boarding belt 3 is composed of one continuous belt that circulates over the entire length of the passenger conveyor. Each drive belt 4a, 4b, 4c is arranged so as to contact the boarding belt 3 in at least a part of each circulation path. The driving belts 4a, 4b, and 4c each transmit a driving force to the boarding belt 3 at a contact portion with the boarding belt.

  The first drive belt 4a is stretched between a folding roller 8 having a large diameter and a folding roller 4f having a small diameter. The second drive belt 4b is stretched between a pair of folding rollers 4g having a small diameter. As in the case of the first drive belt 4a, the third drive belt 4c is stretched between the folding roller 8 having a large diameter and the folding roller 4f having a small diameter. The third drive belt 4 c is configured symmetrically with the first drive belt 4 a from the center position in the longitudinal direction of the passenger conveyor 1.

  The second driving belt 4b is disposed between the first driving belt 4a and the third driving belt 4c, and a folding roller 4f around which the first driving belt 4a and the third driving belt 4c are wound. The folding rollers 4g around which the second drive belt 4b is wound are arranged so as to be adjacent to each other. The boarding belt 3 is stretched between one folding roller 8 arranged on one end side of the main frame 2 and the other folding roller 8 arranged on the other end side of the main frame 2. .

  In the embodiment shown in FIG. 1, the drive belt 4 is configured to come into contact with the boarding belt 3 within the range of the portion of the circulation path of the boarding belt 3 where passengers ride. The driving force may be transmitted from the driving belt 4 to the boarding belt 3 even in a section where the driving belt 4 is close to the boarding belt 3 in the return path portion of the boarding belt 3.

  Next, referring to FIG. 1 and FIG. 2, the first drive mechanism 5a for the first drive belt 4a provided at both ends 1A, 1C of the main frame 2 and the third drive belt 4c. The third drive mechanism 5c for this purpose will be described. Note that the structure of the third drive belt 4c is the same as the structure of the first drive belt 4a. Therefore, the third drive mechanism 5c is also the same as the first drive mechanism 5a. However, the circulation directions are opposite to each other.

  As shown in FIGS. 1 and 2, the first drive mechanism 5 a has a drive pulley 7. The drive pulley 7 is provided so as to mesh with the boarding belt 3 at the turn-up portion 3 a of the boarding belt 3. In order to secure the effective length of the meshing portion, the drive belt 4a is guided to the drive pulley 7 using the guide roller 8a. Specifically, as shown in FIG. 2, the drive belt 4 a is separated from the inner peripheral surface of the boarding belt 3 and detours along the outer peripheral surface of the drive pulley 7, and is overlapped with the boarding belt 3 again by the folding roller 8. The The rotation shaft of the guide roller 8a is rotatably attached to an appropriate part of the main frame 2.

  A timing pulley 9 is provided coaxially with the drive pulley 7. A timing pulley 10 b is attached to the drive shaft 10 a of the electric motor 10. A timing belt 11 is stretched between the timing pulley 10 b and the timing pulley 9. Sprockets may be used instead of the timing pulleys 9 and 10b, and a chain may be hung instead of the timing belt 11.

  When the electric motor 10 drives the timing pulley 10b, the driving pulley 7 rotates in synchronization therewith. As a result, the drive belt 4a is driven and the boarding belt 3 circulates. The folded portions of the boarding belt 3 and the driving belt 4a are wound around the folding roller 8 so as to overlap each other. Therefore, the boarding belt 3 is circulated at a speed equal to that of the driving belt 4a.

  Note that the third drive mechanism 5c also drives the third drive belt 4c to be equal to the moving speed of the boarding belt 3. The configuration of the portion that transmits the driving force from the driving belts 4a, 4b, and 4c to the boarding belt 3 will be described later.

  Next, the second drive belt 4b will be described. The second drive belt 4b is driven by a second drive mechanism 5b provided in the central portion 1B of the main frame 2. As shown in detail in FIG. 3, the second drive mechanism 5 b includes a plurality of drive rollers 12 and a pressure roller 13.

  The second drive belt 4b is sandwiched between the drive roller 12 and the pressure roller 13 in a part of the circulation track. The pressure roller 13 presses the drive belt 4 b against the opposite drive roller 12 by the elastic force of the attached spring 14. As a result, the driving force is reliably transmitted from the driving roller 12 to the second driving belt 4b.

  Each drive roller 12 is provided with a sprocket 15a coaxially therewith. The second drive mechanism 5b further includes sprockets 15b, 15c, and 15d. These sprockets 15b, 15c and 15d are spanned with an endless chain 16 together with the sprocket 15a.

  The sprocket 15b is supported by a spring 16a, and applies tension to the chain 16 by the elastic force of the spring 16a. A timing pulley 17 is attached coaxially with the sprocket 15d. The electric motor 18 shown in FIGS. 1 and 3 has a timing pulley 18b attached to a drive shaft 18a. A timing belt 19 is stretched between the timing pulley 18 b and the timing pulley 17.

  When the electric motor 18 is started and the timing pulley 18b rotates, the chain 16 is circulated in synchronization therewith. As a result, the driving belt 4 b is circulated and the driving force is transmitted to the boarding belt 3. The diameters of the driving roller 12 and the timing pulleys 17 and 18b included in the second driving mechanism 5b are determined so that the moving speed of the driving belt 4b is equal to the moving speed of the riding belt 3.

  In order to synchronize the drive belts 4a, 4b, 4c, they can also be mechanically connected. In this case, as shown by a two-dot chain line in FIG. 1, a timing belt 4e for connecting a driving belt for connecting the folding rollers 4f and 4g is provided. This also compensates for the lack of driving force. That is, the power of the electric motor 18 is further transmitted from the second drive belt 4b to the first drive belt 4a and the third drive belt 4c via the timing belt 4e. As a result, the boarding belt 3 in contact with the drive belts 4a, 4b, and 4c has the electric motor 10 provided in the first drive mechanism 5a and the third drive mechanism 5c and the electric motor provided in the second drive mechanism 5b. 18 is circulated by a stable driving force generated.

  The chain 16 may use other types of endless power transmission members such as timing belts and toothed belts. The timing belts 11 and 19 may use other types of endless power transmission members such as chains and toothed belts. In this case, the sprockets 15a, 15b, 15c, 15d and the timing pulleys 9, 10b, 17, 18b are replaced with timing pulleys, sprockets, and toothed pulleys suitable for the endless power transmission member.

  Next, with reference to FIG. 4, the structure of the mechanism for transmitting the driving force from the driving belt 4 (4a, 4b, 4c) to the boarding belt 3 will be described. FIG. 4 is a perspective view including a cross section taken along line IV-IV in FIG. In FIG. 1, “IV-IV” is indicated at a plurality of locations, and the structures at these locations are substantially the same.

  As shown in FIG. 4, the belt-type passenger conveyor 1 includes guide rails 20 on both sides of the boarding belt 3 along the circulation direction. The guide rail 20 has the same cross-sectional shape as the channel steel. The guide rail 20 is provided only in the section where the boarding belt 3 runs along with the drive belt 4, and is not provided in other sections.

  The boarding belt 3 is a so-called flat belt having a thin cross-section that is the same as that generally used for a conventional belt-type passenger conveyor. As shown in FIG. 4, the drive belt 4 is a so-called flat belt having a rectangular cross section. A support plate 21 is horizontally provided on the lower side of the driving belt 4 in contact with the lower surface of the boarding belt 3 on the passenger boarding side. The support plate 21 supports the drive belt 4.

  It is preferable that means for reducing the frictional force generated between the drive belt 4 and the drive belt 4 is provided on the support plate 21. As a means for reducing the frictional force, there is a method of providing a low-friction resin coating layer on the support plate 21 in addition to a method of providing the support roller 22 on the support plate 21 as shown in FIG. .

  The transmission efficiency of the driving force transmitted from the driving belt 4 to the boarding belt 3 is based on the meshing efficiency or friction coefficient between the driving belt 4 and the boarding belt 3 and the pressing force acting between the boarding belt 3 and the driving belt 4. Dependent.

  In order to improve the meshing efficiency, the soft layer 3d is provided on at least the surface of the boarding belt 3 in contact with the drive belt 4. In this embodiment, the boarding belt 3 is comprised by the core material 3c and the soft layer 3d which covers the circumference | surroundings of this core material 3c.

  On the other hand, the drive belt 4 has an inner peripheral surface 4d with a rough surface roughness, for example, by providing unevenness in order to increase the grip force. Since the rough inner peripheral surface 4d contacts and meshes with the soft layer 3d of the boarding belt 3, the driving force is reliably transmitted between them.

  The core material 3c is disposed along the width direction of the boarding belt 3 and maintains the flat belt cross-sectional shape. The core material 3c prevents the departure from the boarding belt 3 support plate 21. A plurality of core members 3c are provided in parallel with a certain interval in the circulation direction of the boarding belt 3 so as not to impair the flexibility of the boarding belt 3.

  A roller 3e is rotatably attached to a core material 3c protruding in the width direction from the edge portions 3b on both sides of the boarding belt 3. The roller 3e is fitted in the recess of the guide rail 20 to guide the circulating movement of the boarding belt 3. The guide rail 20 may be an L-shaped steel, an I-shaped steel, or an H-shaped steel in addition to the channel shaped steel. The boarding belt 3 and the drive belt 4 can also be configured as shown in FIG. 6 of the second embodiment in order to improve the meshing efficiency between them.

  The drive belt 4 incorporates a plurality of slings 4h as elongation limiting members. The sling 4h is a reinforcing wire and is embedded in the drive belt 4 along the circulation direction, and maintains the strength of the drive belt 4 in the longitudinal direction. For this reason, even when a load is applied to the drive belt 4 due to a passenger getting on the boarding belt 3, the drive belt 4 is not damaged or stretched.

  The meshing force generated between the drive belt 4 and the boarding belt 3 greatly depends on the force with which the boarding belt 3 is pressed against the drive belt 4 when the passenger gets on the boarding belt 3. As more passengers ride on the boarding belt 3, the driving force transmission efficiency from the boarding belt 3 to the driving belt 4 is improved, which is very convenient.

  The pressing force acting between the drive belt 4 and the boarding belt 3 depends on the weight of the boarding belt 3, in particular, the weight of the boarding belt 3 in the area where passengers ride and the tension acting on the boarding belt 3 itself. To do. In particular, the pressing force that acts between the drive belt and the boarding belt at the folded portion of the boarding belt 3 greatly depends on the tension that acts on the entire boarding belt 3.

  Therefore, it is preferable to provide means for applying tension to the boarding belt 3 so that the driving force from the driving belt 4 to the boarding belt 3 is reliably transmitted even when the passenger is not on the boarding belt 3. As the tension applying means, a mechanism provided in a handrail belt driving device in a conventional belt-type passenger conveyor can be used. However, the tension applied to the boarding belt 3 by the tension applying means may be significantly smaller than the boarding belt of a conventional belt type passenger conveyor. Therefore, the load applied to the boarding belt 3 is very small.

  As shown in FIG. 1, the belt-type passenger conveyor 1 has a support roller 23 that supports and guides the boarding belt 3 in a section where the guide rail 20 and the support plate 21 are interrupted. The support roller 23 can be replaced with a guide rail having an appropriate shape.

  Further, a guide roller or a pulley is provided as appropriate in a section where the boarding belt 3 is bent at least in the main frame in a range where passengers do not get on. When tension applying means such as that provided in a conventional belt driving device is provided on the boarding belt, a tensioner roller for applying tension is provided in the vicinity of the section where the boarding belt is bent.

  According to this embodiment, the following advantageous effects can be obtained.

  A belt used for a passenger conveyor is required to have a mechanical strength that can withstand high tension and a texture such as a feel and appearance when a passenger gets on the belt. As long as the conventional belt driving device is used, it has been difficult to satisfy these requirements simultaneously. On the other hand, according to the belt type passenger conveyor 1 of this embodiment, the drive belt 4 should just have high mechanical strength, and the mechanical strength of the boarding belt 3 regarding a circulation direction may be low.

  The power of the electric motors 10 and 18 is transmitted to the drive belt 4, and the drive belt 4 is circulated and moved by the power. The boarding belt 3 meshes with the drive belt 4 and simply circulates integrally with the drive belt 4. That is, since the boarding belt 3 receives almost no load in the circulation direction, the mechanical strength may be low.

  Therefore, it is possible to design the boarding belt 3 with an emphasis on texture in the belt type passenger conveyor 1. In addition, maintenance of the cross-sectional shape of the boarding belt 3 can be easily realized without sacrificing the texture by providing the core material 3c as shown in FIG.

  The drive belt 4 can be easily formed because a flat belt with a simple cross-sectional shape can be used. Since it is sufficient that the drive belt 4 has a substantially sufficient strength in the circulation direction, it is easy to ensure the strength. Further, the shape of the roller 8 around which the drive belt 4 is wound may be simple.

  Since the entire shape of the boarding belt 3 can be made the same as the conventional shape, the passenger can feel the same and the safety is assured as before. Furthermore, since the boarding belt 3 is configured not to slide relative to the drive belt 4, the boarding belt 3 does not move idly when the emergency stop is performed, and the same safety as the conventional one can be ensured.

  Further, since the driving force is transmitted from the driving belts 4a, 4b, 4c to the boarding belt 3 at a plurality of locations, it is possible to prevent an excessive load from being applied to any one of the driving belts 4a, 4b, 4c. Can do. In other words, no matter how long the entire length of the boarding belt 3 is, a sufficient driving force can be supplied by increasing the number of the driving belts 4.

  Note that the drive belt 4 and the drive mechanism 5 configured based on the present invention may be configured to be provided only on one passenger conveyor. In the embodiment, the first drive mechanism 5a and the second drive mechanism 5b have different configurations. However, the present invention is not limited to this. The plurality of drive mechanisms 5 may all have the same configuration.

[Second Embodiment]
A belt-type passenger conveyor 31 according to the second embodiment will be described with reference to FIGS. 5 and 6. The passenger conveyor 31 has an “intermediate acceleration type” configuration in which the speed of the boarding belt 33 in the intermediate portion 31B is higher than the speed of the end portions 31A and 31C serving as entrances and exits. In the second embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

  As shown in FIG. 5, the passenger conveyor 31 includes a boarding belt 33, a first drive belt 34a, a second drive belt 34b, and a third drive belt 34c. The boarding belt 33 is a belt on which passengers are directly placed, and circulates and moves along a circulation path provided in the main frame 32. The first drive belt 34a and the third drive belt 34c are disposed near the end portions 31A and 31C of the passenger conveyor on the entrance side or the exit side, and drive the boarding belt 33. The second drive belt 34 b is disposed in the intermediate portion 31 </ b> B of the passenger conveyor 1 and drives the boarding belt 33.

  The first drive belt 34a and the third drive belt 34c extend along the transport direction as relatively short sections of the end portions 31A and 31C. On the entrance side, the drive belt is folded back together with the boarding belt 33 and guided to the upper side of the roller 8. On the exit side, the drive belt is folded back together with the boarding belt 33 and guided to the lower side of the roller 8. The most part of the entire length of the passenger conveyor 31 is occupied by the second drive belt 34b. The second drive belt 34b may be divided into a plurality of parts and share the driving force for the boarding belt 33.

  Each drive belt 34a, 34b, 34c has a drive mechanism 35 (the first drive mechanism 35a, the second drive mechanism 35a having the same configuration as the first drive mechanism 5a described above with reference to FIGS. 1 and 2). Driven by the driving mechanism 35b and the third driving mechanism 35c). At this time, the first drive belt 34a is circulated at a speed V1, and the second drive belt 34b is circulated at a speed V2 larger than the speed V1.

  In order to provide a speed difference between the first drive belt 34a and the second drive belt 34b, the diameters of roller sprockets and timing pulleys provided in the drive mechanisms 35a and 35b are appropriately set. The second drive mechanism 35b shown in FIG. 5 is the same as the second drive mechanism 5b shown in FIG. 3, but the positional relationship between the pressure roller 13 and the drive roller 12 is upside down across the boarding belt 33. It has become. The drive roller 12 of the second drive mechanism 35b shown in FIG. 5 has a tooth groove on the outer periphery. As shown in FIG. 6, a tooth groove 34 d is formed on the outer peripheral surface of the drive belt 34 b and meshes with the tooth groove of the drive roller 12.

  The boarding belt 33 is a member that elastically extends at least ((V2 / V1) -1) × 100% in the circulation direction. In the passenger conveyor 31, the first drive belt 34a, the second drive belt 34b, and the third drive belt 34c are driven at speeds V1, V2, and V1, respectively. Accordingly, the boarding belt 33 is extended, so that the boarding belt 33 is moved at the speed V1 in the vicinity of the end portions 31A and 31C and at the speed V2 in the intermediate portion 31B.

  The reason why the stretchable member can be used for the boarding belt 33 as described above is that the boarding belt 33 does not require a high strength in the circulation direction as described in the section of the effect of the first embodiment. It is.

  As shown in FIG. 6, the boarding belt 33 used in the passenger conveyor 31 is also a flat belt having a thin cross-section that is the same as that used in a conventional belt-type passenger conveyor. Edge portions on both sides in the width direction of the boarding belt 33 are supported by guide rollers 36. The boarding belt 33 has a plurality of core members 33a arranged at equal intervals in the circulation direction of the boarding belt 33 as in the first embodiment.

  The plurality of core members 33a are connected to each other by an expansion / contraction sling 33b. The expansion / contraction sling 33b is an elongation limiting member that allows elastic stretching necessary in the circulation direction of the boarding belt 33 and prevents excessive stretching of the boarding belt 33. The core material 33 a and the elastic sling 33 b are embedded in a covering layer 33 c made of an elastic material that constitutes the boarding belt 33.

  In the second embodiment, there is a difference between the speed V1 of the first drive belt 34a and the speed V2 of the second drive belt 34b. For this reason, it is necessary to prevent slipping between the boarding belt 33 and the drive belts 34a, 34b, and 34c. A higher transmission efficiency of the driving force is required between the boarding belt 33 and the driving belts 34a, 34b, 34c, in other words, a reliable engagement between the boarding belt 33 and the driving belts 34a, 34b, 34c is required.

  Therefore, the tooth groove 33d is formed on the inner peripheral surface of the boarding belt 33, and the tooth groove 34d is formed on the outer peripheral surface of the drive belts 34a, 34b, 34c. At this time, the tooth groove 33d and the tooth groove 34d are formed in complementary shapes, respectively. The shape of these tooth grooves 33d and 34d is not only the uneven shape as shown in FIG. 6 is applied to the surface of the boarding belt 33 and the drive belts 34a, 34b and 34c, but also the shape of triangular waves such as peaks and valleys, It is also possible to have a shape like a gear tooth groove.

  As shown in FIG. 6, the core material 33 a has a core material protrusion 33 e that protrudes toward the inner peripheral surface of the boarding belt 33. The core protrusion 33e meshes with the tooth groove 34d of the drive belts 34a, 34b, 34c. Thereby, since the core material 33a meshes with the driving belt 34 firmly, the transmission efficiency of the driving force is improved.

  In addition to the case where the tip shape of the core material protruding portion 33e is formed to match the groove shape of the tooth groove 34d of the drive belts 34a, 34b, 34c, the tip shape of the core material protruding portion 33e is rectangular and the drive belt 34a. , 34b, 34c may be provided with a rectangular groove in which the core material protrusion 33e meshes. Further, the meshing structure of the boarding belt 33 and the drive belts 34a and 34b shown in FIG. 6 can naturally be applied to the first embodiment.

  A steel strip 34e is embedded in the drive belts 34a, 34b, 34c in order to increase the strength and rigidity in the circulation direction. The steel strip 34e may be the reinforcing sling 4h shown in the first embodiment. Compared with the drive belt 4 shown in FIG. 4, the drive belts 34a, 34b, and 34c have a surface shape provided with tooth grooves 34d and a steel strip 34e as a reinforcing material, as shown in FIG. Is different.

  The boarding belt 33 expands rapidly when moving from the driving belt 34a to the driving belt 34b, and contracts rapidly when moving from the driving belt 34b to the driving belt 34c. Therefore, in order to prevent deterioration of the boarding belt 33, it is preferable to prevent a local load from being applied to the boarding belt 33. As an example, the speed changing means 37 shown in FIG. 6 is provided between the first drive belt 34a and the second drive belt 34b. The speed changing means 37 is provided to gradually change the speed of the boarding belt 33 from V1 to V2.

  Hereinafter, the speed changing means 37 will be described in detail with reference to FIG. As shown in FIG. 6, the speed changing means 37 has a plurality of roller sets 38. The roller set 38 includes drive rollers 38a3 and 38a4 that are wide rollers having substantially the same width as the drive belt, and transmission rollers 38b1, 38b2, 38b3, 38b4, and 38b5 that are relatively narrow rollers. , 38b6, 38b7.

  Tooth grooves 38c3 and 38c4 that can mesh with the tooth grooves 33d formed on the inner peripheral surface of the boarding belt 33 are provided on the outer peripheral surfaces of the drive rollers 38a3 and 38a4. The transmission roller 38b1 is provided coaxially with the folding roller 4f. The transmission roller 38b2 is provided coaxially with the folding roller 4g. The transmission roller 38b3 is provided coaxially with the drive roller 38a3. The transmission roller 38b4 is provided coaxially with the drive roller 38a4. The transmission roller 38b5 is in contact with the transmission rollers 38b1 and 38b3, respectively. The transmission roller 38b6 is in contact with the transmission rollers 38b3 and 38b4, respectively. The transmission roller 38b7 is in contact with the transmission rollers 38b4 and 38b2.

  In order to ensure power transmission between the transmission rollers 38b1, 38b2, 38b3, 38b4, 38b5, 38b6, 38b7, the transmission rollers 38b5, 38b6, 38b7 are transmitted by the springs 38e5, 38e6, 38e7 by the transmission rollers 38b1, 38b2, 38b3, 38b4. It is pressed against.

  Here, the rotational peripheral speeds of the drive rollers 38a3 and 38a4 are set so as to increase gradually from the circulation speed of the first drive belt 34a to the circulation speed of the second drive belt 34b. Specifically, the diameter ratio of the transmission rollers 38a1, 38a2, 38a3, and 38a4 to the folding rollers 4f and 4g and the driving rollers 38a3 and 38a4 is stepwise from the first driving belt 34a side to the second driving belt 34b side. Is set to be smaller.

  Further, the moving speed is reduced from the second drive belt 34b to the third drive belt 34c. Therefore, the rotational peripheral speed of the driving roller of the roller set 38 provided as the speed changing means 37 between the second driving belt 34b and the third driving belt 34c is determined based on the circulation speed of the second driving belt 34b. The speed is set so as to be gradually reduced to the circulation speed of the drive belt 34c. That is, the diameter ratio of the transmission roller with reference to the folding roller and the driving roller is set to be larger.

  The outer peripheral surfaces of the transmission rollers 38b1, 38b2, 38b3, 38b4, 38b5, 38b6, and 38b7 may be smooth as long as frictional force is generated to the extent that the driving force is transmitted to each other. Specifically, the outer peripheral surface of each transmission roller is preferably formed of a soft material having a high degree of adhesion. Alternatively, a tooth groove may be provided on the outer peripheral surface of the transmission roller, and the driving force may be transmitted by meshing the tooth grooves between the transmission rollers 38b1, 38b2, 38b3, 38b4, 38b5, 38b6, 38b7.

  Since the speed changing unit 37 has the above-described configuration, the peripheral speed of the drive rollers 38a3 and 38a4 increases as the speed is closer to the second drive belt 34b. The peripheral speed of the drive roller 38a3 on the side close to the first drive belt 34a is slightly larger than the circulation speed of the first drive belt 34a, and the peripheral speed of the drive roller 38a4 on the side close to the second drive belt 34b is The diameter of each transmission roller is determined so as to be smaller than the circulation speed of the second drive belt 34b.

  The same applies when there are two or more drive rollers. If the peripheral speed of the driving roller changes stepwise between the first driving belt 34a and the second driving belt 34b, the configuration of the driving roller and the transmission roller between the folding rollers 4f and 4g is as described above. Other than that.

  The speed of the boarding belt 33 that moves away from the first drive belt 34a toward the second drive belt 34b increases stepwise from V1 to V2. As a result, the boarding belt 33 is extended stepwise between the first drive belt 34a and the second drive belt 34b. Therefore, it is possible to prevent a large load from being locally applied to the boarding belt 33.

  The boarding belt 33 reaching the second drive belt 34b extends by ((V2 / V1) -1) × 100% with respect to the case where the boarding belt 33 is on the first drive belt 34a. And it will move with the 2nd drive belt 34b, maintaining the state. Therefore, the tooth groove 33d formed in the boarding belt 33, the tooth groove 34d1 formed in the first drive belt 34a, and the tooth groove 34d2 formed in the second drive belt 34b are securely engaged. The pitch P2 of the tooth groove 34d2 is set to V2 / V1 times the pitch P1 of the tooth groove 34d1.

  Further, the pitch of the tooth grooves 38c1 and 38c2 formed in the drive rollers 38a3 and 38a4 is set larger than the pitch P1 of the tooth groove 34d1 and smaller than the pitch P2 of the tooth groove 34d2. The pitch of the tooth groove 38c4 of the drive roller 38a4 on the side close to the second drive belt 34b is set larger than the pitch of the tooth groove 38c3 of the drive roller 38a3 on the side close to the first drive belt 34a.

  When the speed of the boarding belt 33 changes as described above, it is preferable to inform the passenger of that fact. Therefore, the first drive belt 34a and the second drive belt 34b are colored in different colors or colors. In this case, at least a part of the boarding belt 33, particularly its covering layer 33c, is formed of a translucent material so that the passenger can visually recognize the colors of the driving belts 34a and 34b and the driving rollers 38a3 and 38a4. Is done. As the translucent material, a transparent or translucent member may be used, or a large number of holes may be provided on the net.

  As an example of coloring, the color of the second drive belt 34b may be colored to a color that images high speed, and the color of the first drive belt 34a may be colored to a color that images slower speed. For example, the second drive belt 34b is colored red, and the first drive belt 34a is colored yellow. Further, if the color of the driving rollers 38a3 and 38a4 having an intermediate speed is orange, which is an intermediate color between red and yellow, it is possible to visually indicate that the moving speed is gradually changing.

  At this time, it is preferable that the color of the drive rollers 38a3 and 38a4 is closer to yellow as the color is closer to the first drive belt 34a, and closer to red as the color is closer to the second drive belt 34b.

  The colors of the drive belts 34a, 34b, 34c and the drive rollers 38a3, 38a4 may be chromatic colors other than yellow, orange, and red, and are not limited to chromatic colors but are achromatic colors with different gradations. Also good. The color change from the drive belt 34a to the drive belt 34b via the drive rollers 38a3 and 38a4 may be a gradation due to a change in lightness or a change in saturation.

  FIG. 6 shows a portion where the first driving belt 34a is changed to the second driving belt 34b at one end 31A which becomes the entrance or exit of the belt type passenger conveyor 31. As shown in FIG. Also on the opposite end 31C of the belt type passenger conveyor 31, a third drive belt 34c having the same structure as the first drive belt 34a and a third drive mechanism 35c similar to the first drive mechanism 35a are arranged. ing. A speed changing means 37 having the same structure as the speed changing means 37 is disposed between the third drive mechanism 35c and the second drive mechanism 35b.
